Newtons Law Of Motion Computer Science Essay

In this assignment, I will larn about the result two that is Newton ‘s jurisprudence and harmonic oscillation. Newton ‘s jurisprudence can be divide by three types that is 1st jurisprudence, 2nd jurisprudence and 3rd jurisprudence. It is teach about the gesture in our existent life. Thus, harmonic oscillation can be divided by three types that are pendulum oscillation, damped oscillation and mechanic oscillation. All of these oscillation are utile in our life especial is use in different type of mechanics.Question OneResearch on the Newton ‘s Laws of gesture, and do a study that provide item account and illustrations on Newton ‘s 3 Torahs of gesture. You report should include relevant and utile expression.AnswerNewton ‘s jurisprudence of gesture can be divided by three types that is 1st jurisprudence, 2nd jurisprudence and 3rd jurisprudence and it is jurisprudence of gravitation. The three Torahs are simple and reasonable. The first jurisprudence provinces that a force must be applied to an object in order to alter its speed. When the object ‘s speed is altering that average it is speed uping, which implies a relationship between force and acceleration. The 2nd jurisprudence, the acceration of an object is straight relative to the net force moving on it and is reciprocally relative to its mass. The way of the acceleration is in the way of the acceleration is in the way of the net force moving on the object. Finally, the 3rd Torahs, whenever we push on something, it pushes back with equal force in the opposite way.ForcesA force is normally imagined as a push or a pull on some object, possibly quickly, as when we hit a tennis ball with a racket. ( see figure 1.0 ) . We can hit the ball at different velocities and direct it ionto different parts of the oppositions ; s tribunal. This mean that we can command the magnitude of the applied force and alos its way, so force is a vector measure, merely like speed and acceleration. Figure 1.0: Tennis title-holder Rafael Nadal strikes the ball with his racket, using a force and directing the ball into the unfastened portion of the tribunal. Figure 1.1: Examples of forces applied to assorted objects. In each instance, a force acts on the object surrounded by the dotted lines. Something in the environment external to the boxed country exerts the force.Newton ‘s 1st jurisprudenceNewton ‘s 1st jurisprudence of gesture provinces that if a organic structure is at remainder it will stay at the remainder and if a organic structure is traveling in a consecutive line with unvarying speed will maintain traveling unless an external force is acted upon. For illustration, see a book lying on a tabular array. Obviously, the book remains at remainder if left entirely. Now imagine forcing the book with a horizontal force great plenty to get the better of the force of clash between the book and the tabular array, puting the book in gesture. Because the magnitude of the applied force exceeds the magnitude of the clash force, the book to a halt. Now imagine the book across a smooth floor. The book once more comes to rest one time the force is no longer applied, but non every bit rapidly as earlier. Finally, if the book is traveling on a horizontal frictionless surface, it continues to travel in a consecutive line with changeless speed until it hits a wall or some other obstructor. However, an object moving on a frictionless surface, it ‘s non the nature of an object to halt, one time set in gesture, but instead to continues in its original province of gesture. This attack was subsequently formalized as Newton ‘s first jurisprudence of gesture: An object moves with a speed that is changeless in magnitude and way, unless acted on by a nonzero net force. For illustration: In the figure 1.2, the twine is supplying centripetal force to travel the ball in a circle around 3600. If sudden the twine was break, the ball will travel off in a consecutive line and the gesture in the absence of the restraining force. This illustration is non hold other net forces are moving, such as horizontal gesture on a frictionless surface. Figure 1.2InactivenessInertia is the reluctance of an object to alter its province of gesture. This means if an object is at remainder it will stay at remainder or if it ‘s traveling it will maintain traveling in a consecutive line with unvarying speed. Force is needed to get the better of inactiveness.For illustrationIn figure 1.3, it is an experiment to turn out the construct of inactiveness. In experiments utilizing a brace of inclined planes confronting each other, Galileo observed that a ball would up the opposite plane to the same tallness and turn over down one plane. If smooth surface are used, the ball is roll up to the opposite plane and return to the original tallness. When it is get downing to turn over down the ball on the degree topographic point, it is will return the ball at the same tallness from original point. Figure 1.3 If the opposite slope were elevated at about a 0 grade angle, so the ball will be roll in an attempt to make the original tallness that is show in the figure 1.4. Figure 1.4: If a ball stops when it attains its original tallness, so this ball would ne'er halt. It would turn over everlastingly if clash were absent.Other illustrationFigure 1.5: Harmonizing to Newton ‘s 1st jurisprudence, a bikes gesture was n't alteration until same force, such as braking makes it alteration.Newton 2nd jurisprudenceNewton ‘s first jurisprudence explains what happens to an object that has no net force moving on it. The object either remains at remainder or continues traveling in a consecutive line with changeless velocity. Newton ‘s 2nd jurisprudence is the acceleration of an object is straight relative to the net force moving on it and is reciprocally relative to its mass. The way of the acceleration is in the way of the acceleration is in the way of the acceleration is in the way of the net force moving on the object. Imagine forcing a block of ice across a frictionless horizontal surface. When you exert some horizontal force on the block, it moves with an acceleration of the 2m/s2. If you apply a force twice every bit big, the acceleration doubles to 4m/s2. Pushing three times as difficult triples the acceleration, and so on. From such observations, we conclude that the acceleration of an object is straight relative to the net force moving on it. Mass besides affects acceleration. Suppose you stack indistinguishable block of ice on top of each other while forcing the stack with changeless force. If the force applied to one block produces an acceleration of 2m/s2, so the acceleration drops to half that value, 1 m/s2, When 2 blocks are pushed, to one-third the initial value. When three block is pushed, and so on. We conclude that the acceleration of an object is reciprocally relative to its mass. These observations are summarized in Newton ‘s 2nd jurisprudence: The acceleration of an object is straight relative to the net force moving on it and reciprocally relative to its mass.Unit of measurements of Force and MassThe SI unit of force is the Newton. When 1 Newton of force Acts of the Apostless on an object that has a mass of 1 kilograms, it produces an acceleration of 1 m/s2 in the object. From this definition and Newton ‘s 2nd jurisprudence, we can see that the Newton can be expressed in footings of the cardinal units of mass, length and clip. 1 N = 1 kg.m/s2 A force is a push or a pull. Hence a force can alter the size, form, and province of remainder or gesture, way of gesture and velocity / speed. The symbol for force is F and the S.I. unit is Newton ( N ) . An object of mass m is subjected to a force F, its speed alterations from U to V in clip t. The above status can be stated as: F = Where a = is acceleration, therefore F = mom.For illustrationFigure 1.6: An airboat. An airboat with mass 3.50x102Kg, including riders, has an engine that produces a net horizontal force of 7.70x102N, after accounting for forces of opposition ( see figure 1.6 ) . ( a ) Find the acceleration of the airboat. ( B ) Get downing from remainder, how long does it take the airboat to make a velocity of 12.0m/s2? ( degree Celsius ) After making this velocity, the pilot turns off the engine and impetuss to a Michigan over distance of 50.0m. Find the opposition force, presuming it ‘s changeless.Solution( a ) Find the acceleration of the airboat. Apply Newton ‘s 2nd jurisprudence and work out for the acceleration: Fnet = mom a = = = 2.20m/s2 ( B ) Find the clip necessary to make a velocity of 12.0m/s. Use the kinematics velocity equation: If t = 5.45s V = at + V0 = ( 2.20m/s2 ) ( 5.45 ) = 12.0m/s ( degree Celsius ) Find the opposition force after the engine is turned off. Using kinematics, find the net acceleration due to resistance forces V2 – = 2a I†x 0 – ( 12.0m/s ) 2 = 2a ( 50.0m ) = -12 / 100 = -0.12m/s2 Substitute the acceleration into Newton ‘s 2nd jurisprudence, happening the opposition force: Fresistance= mom = ( 3.50 X 102kg ) ( -144m/s2 ) = -504NImpulse and Impulsive ForceThe force, which acts during a short minute during a hit, is called Impulsive Force. Impulse is defined as the alteration of impulse, so Impulse = MV – Mu, since F = , therefore impulse can be written as: Impulsive force is Force = Impulse/Time. Unit is Newton ( N ) .The applications of unprompted forceIn existent life we tend to diminish the consequence of the unprompted force by cut downing the clip taken during hit.Gravitational force or gravitationGravity exists due to the Earth ‘s mass and it is Acts of the Apostless towards the centre of Earth. Object falling under the influence of gravitation will see free autumn. Assuming no other force acts upon it. Object sing free autumn will fall with acceleration ; gravitation has an approximative value of 10m/s2. The gravitative force moving on any object on Earth can be expressed as F=mg. This is besides every bit weight.For illustrationFind the gravitative force exerted by the Sun on a 79.0kg adult male located on Earth. The distance from the Sun to the Earth is about 1.50 Ten 1011 m, and the Sun ‘s mass is 1.99 Ten 1030kg.SolutionFsun = G = ( 6.67 X 10-11 Kg-1m3s2 ) = 0.413NNewton ‘s 3rd jurisprudenceThe action of one organic structure moving upon another organic structure tends to alter the gesture of the organic structure acted upon. This action is called a force. Because a force has both magnitude and way, it is a vector measure, and the old treatment on vector notation applies. Newton ‘s 3rd jurisprudence is the sum of force which you inflict upon on others will hold the same repelling force that act on you every bit good. Force is exerted on an object when it comes into contact with some other object. See the undertaking of driving a nail into a block of wood, for illustration, as illustrated in the figure 1.7 ( a ) . To speed up the nail and drive it into the block, the cock must exercise a net force on the nail. Newton is a individual stray force ( such as the force exerted by the cock on the nail ) could n't be. Alternatively, forces in nature ever exist in braces. Harmonizing to Newton, as the nail is driven into the block by the force exerted by the cock, the cock is slowed down and stopped by the force exerted by the nail. Newton described such mated forces with his 3rd jurisprudence: Whenever one object exerts a force on a 2nd object, the 2nd exerts an equal and opposite force on the first. This jurisprudence, which is illustrated in figure 1.7 ( B ) , province that a individual stray force ca n't be. The force F12 exerted by object 1 on object 2 is sometimes called the action force, and the force F12 exerted by object 2 on object 1 is called the reaction force. In world, either, either force can be labeled the action or reaction force. The action force is equal in magnitude to the reaction force and antonym in way. In all instances, the action and reaction forces act on different objects. For illustration, the force moving on a freely falling missile is the force exerted by Earth on the missile, Fg, and the magnitude of this force is its weight milligram. The reaction to coerce Fg is the force exerted by the missile on Earth, Fg = -Fg. The reaction force Fg must speed up the Earth towards the missile, merely as the action force Fg accelerates the missile towards the Earth. Because the Earth has such a big mass and its acceleration due to this reaction forces is negligibly little. Figure 1.7: Newton ‘s 3rd jurisprudence. ( a ) The force exerted by the cock on the nail is equal in magnitude and antonym in way to the force exerted by the nail on the cock. ( B ) The force F12 exerted by object 1 on object 2 is equal in magnitude and antonym in way to the force F21 exerted by object 2 on object 1. Newton ‘s 3rd jurisprudence invariably affects our activities in mundane life. Without it, no motive power of any sort would be possible, whether on pes, on a bike, or in a motorised vehicle. When walking, we exert a frictional force against the land. The reaction force of the land against our pes propels us frontward. In the same manner, the tired on a bike exert a frictional force against the land, and the reaction of the land pushes the bike frontward. This is called clash plays a big function in such reaction forces. Figure 1.8: In the figure 1.8, when a force pushes on an object, the object pushes back in the opposite way. The force of the forcing back is called the reaction force. This jurisprudence explains why we can travel a dinghy in H2O. The H2O pushes back on the oar every bit much as the oar pushes on the H2O, which moves the boat. The jurisprudence besides explains why the pull of gravitation does n't do a chair clang through the floor ; the floor pushes back plenty to countervail gravitation. When you hit a baseball, the chiropteran pushes on the ball, but the ball besides on the chiropteran. Figure 1.9Question TwoResearch and exemplify the assorted features of â€Å" Damped Oscillations † , your reply should besides include graphical show of these characteristic.AnswerIn the existent life, the vibrating gesture can be taken topographic point in ideal systems that are hovering indefinitely under the action of a additive restoring force. In many realistic system, resistive forces, such as clash, are present and retard the gesture of the system. Consequently, the mechanical energy of the system diminishes in clip, and the gesture is described as a damped oscillation. Therefore, in all existent mechanical systems, forces of clash retard the gesture, so the systems do n't hover indefinitely. The clash reduces the mechanical energy of the system as clip base on ballss, and the gesture is said to be damped. In the figure 2.0, daze absorbers in cars are one practical application of damped gesture. A daze absorber consists of a Piston traveling through a liquid such as oil. The upper portion of the daze absorber is steadfastly attached to the organic structure of the auto. When the auto travels over a bump in the route, holes in the Piston let it to travel up and down in the fluid in a damped manner. ( B ) Figure 2.0: ( a ) Angstrom daze absorber consists of a Piston hovering in a chamber filled with oil. As the Piston oscillates, the oil is squeezed through holes between the Piston and the chamber, doing a damping of the Piston ‘s oscillations. ( B ) One type of automotive suspension system, in which a daze absorber is placed inside a spiral spring at each wheel. Damped gesture varies with the fluid used. For illustration, if the fluid has a comparatively low viscousness, the vibrating gesture is preserved but the amplitude of quiver lessenings in clip and the gesture finally ceases. This procedure is known as under damped oscillation. The place vs. clip curve for an object undergoing such as oscillation appears in active figure 2.1. In the figure 2.2 compares three types of damped gesture, with curve ( a ) stand foring underdamped oscillation. If the fluid viscousness is increased, the object return quickly to equilibrium after it is released and does n't hover. In this instance the system is said to be critically damped, and is shown as curve ( B ) in the figure 2.2. The Piston return to the equilibrium place in the shortest clip possible without one time overshooting the equilibrium place. If the viscousness is greater still, the system is said to be overdamped. In this instance the Piston returns to equilibrium without of all time go thro ughing through the equilibrium point, but the clip required to make equilibrium is greater than in critical damping. As illustrated by curve ( degree Celsius ) in figure 2.2. Active figure 2.1: A graph of displacement versus clip for an under damped oscillator. Note the lessening in amplitude with clip. Figure 2.2: Plots of displacement versus clip for ( a ) an under damped oscillator, ( B ) a critically damped oscillator, and ( degree Celsius ) an overdamped oscillator. Damped oscillation is relative to the speed of the object and Acts of the Apostless in the way opposite that of the object ‘s speed relation to the medium. This type of force is frequently observed when an object is hovering easy in air, for case, because the resistive force can be expressed as R = -bv, where B is a changeless related to the strength of the resistive force, and the reconstructing force exerted on the system is -kx, Newton ‘s 2nd jurisprudence gives us = -kx – bv = soap -kx – B = m ~ ( I ) The solution of this differential equation requires mathematics that may non yet be familiar to you, so it will merely be started without cogent evidence. When the parametric quantities of the system are such that B & lt ; so that the resistive force is little, the solution to equation is Ten = ( Ae- ( b/2m ) T ) cos ( wt + ) ~ ( two ) Where the angular frequence of the gesture is = ~ ( three ) The object suspended from the spring experience both a force from the spring and a resistive force from the environing liquid. Active figure 2.1 shows the place as a map of clip for such a damped oscillator. We see that when the resistive force is comparatively little, the oscillating character of the gesture is preserved but the amplitude of quiver lessenings in clip and the gesture finally creases, this system is known as an underdamped oscillator. The dotted blue lines in active figure 2.1, which form the envelope of the oscillatory curve, represent the exponential factor that appears in equation ( two ) . The exponential factor shows that the amplitude decays exponentially with clip. It is convenient to show the angular frequence of quiver of a damped system ( three ) in the signifier=Where = a?sk/m represents the angular frequence of oscillation in the absence of a resistive force ( the undamped oscillator ) . In other words, when b=o, the resistive force is zero and the system oscillates with angular frequence, called the natural frequence. As the magnitude of the resistive force additions, the oscillations dampen more quickly. When B reaches a critical value bc, so that bc/2m = , the system does non hover and is said to be critically damped. In this instance, it returns to equilibrium in an exponential mode with clip, as in figure 2.2. Question Three: Simple Harmonic Motion ( SHM ) is a dynamical system typified by the gesture of a mass on a spring when it is capable to the additive elastic reconstructing force given by Hooke ‘s Law. The gesture is sinusoidal in clip and demonstrates a individual resonant frequence. What is the relationship between the tenseness and weight in the system? What is Hooke ‘s jurisprudence when applied to the system?AnswerOscillation of gesture is has one set of equations can be used to depict and foretell the motion of any object whose gesture is simple harmonic. The gesture of a vibrating object is simple harmonic if its acceleration is relative to its supplanting and its acceleration and supplanting are in opposite way. The 2nd slug point mean that are acceleration, and hence the end point force, ever acts towards the equilibrium place, where the supplanting is zero. Common illustrations of simple harmonic gesture include the oscillations of a simple pendulum and those of a mass suspended vertically on a spring. The diagram shows the size of the acceleration of a simple pendulum and a mass on a spring when they are given a little supplanting, x, from the equilibrium place. Figure 3.0 In the figure 3.0, the numerical value of the acceleration is equal to a changeless multiplied by the supplanting, demoing that acceleration is relative to displacement. Then, the negative value of the acceleration shows that it is in the opposite way to the supplanting, since acceleration and supplanting are both vector measures.Simple harmonic in a springIf you hang a mass from a spring, the mass will stretch the spring a certain sum and so come to rest. It is established when the pull of the spring upward on the mass is equal to the pull of the force of gravitation downward on the mass. The system, spring and mass, is said to be in equilibrium when that status is met. If the mass is up or down from the equilibrium place and release it, the spring will undergo simple harmonic gesture caused by a force moving to reconstruct the vibrating mass back to the equilibrium place. That force is called the restoring force and it is straight relative to magnitude of the supplanting and is directed opposite the supplanting. The necessary status for simple harmonic gesture is that a reconstructing force exists that meets the conditions stated symbolically as Fr = -kx, where K is the invariable of proportionality and ten is the supplanting from the equilibrium place. The subtraction mark, as usual, indicates that Fr has a way opposite that of ten.For illustrationFigure 3.1 The grouch rotates with angular speed w. Then, the slide will skid between P1 and P. V2 = W2 ( P2-X2 ) P = Amplitude or maximal point. V= Velocity of the skidder. Ten = Distance from centre point due to speed, V. W = Angular speed of grouch. = 2Iˆf degree Fahrenheit = = 1/T a = -w2xSimple pendulumA simple pendulum is merely a heavy atom suspended from one terminal of an nonextensile, weightless twine whose other terminal in fixed in a stiff support, this point being referred to as the point of suspension of the pendulum. Obviously, it is merely impossible to obtain such an idealised simple pendulum. In existent pattern, we take a little and heavy spherical British shilling tied to a long and all right silk yarn, the other terminal of which passes through a split cork firmly clamped in a suited base, the length ( a„â€Å" ) of the pendulum being measured from the point of suspension to the Centre of mass of the British shilling. In the figure 3.2, allow S be the point of suspension of the pendulum and 0, the mean or equilibrium place of the British shilling. On taking the British shilling a small to one side and so gently let go ofing it, the pendulum starts hovering about its average place, as indicated by the flecked lines. At any given blink of an eye, allow the supplanting of the pendulum from its average place SO into the place SA is I? . Then, the weight milligram of the British shilling, moving vertically downwards, exerts a torsion or minute – mg/sin I? about the point of suspension, be givening to convey it back to its average place, the negative mark of the torsion bespeaking that it is oppositely straight to the supplanting ( I? ) . Figure 3.2 If d2I?/dt2 be the acceleration of the British shilling, towards 0, and I its M.I about the point of suspension ( S ) , the minute of the force or the torsion moving on the bobn is besides equal to I.d2I?/dt2. I = -mga„â€Å"sinI? If I? is little, the amplitude of oscillation be little, we may pretermit all other footings except the first and take wickedness I? = I? . I = -mga„â€Å"I? , Whence, = Since M.I of the British shilling about the point of suspension ( S ) is ma„â€Å"2. We have = = = A µI? , Where = A µ The acceleration of the British shilling is therefore relative to its angular supplanting I? and is directed towards its average place 0. The pendulum therefore executes a simple harmonic gesture and its clip period is given by T = 2Iˆ = 2Iˆ = 2Iˆ It being clearly understood that the amplitude of the pendulum is little. The supplanting here being angular, alternatively of additive, it is evidently an illustration of an angular simple harmonic gesture.Hooke ‘s jurisprudenceVibration gesture is an object attached to a spring. We assume the object moves on a frictionless horizontal surface. If the spring is stretched or compressed a little distance ten from its equilibrium place and so released, it exerts a force on the object as shown in figure 3.3. From experiment the spring force is found to obey the equation F = -kx ~ ( four ) Where ten is the supplanting of the object from its equilibrium place ( x=0 ) and K is a positive invariable called the spring invariable. This force jurisprudence for springs is known as Hooke ‘s jurisprudence. The value of K is a step of the stiffness of the spring. Stiff springs have big K value, and soft springs have little K value. In the equation ( four ) , the negative mark mean that the force exerted by the spring is ever directed opposite the supplanting of the object. When the object is to the right of the equilibrium place, as in figure 3.3 ( a ) , x is positive and F is negative. This means that force is the negative way, to the left. When the object is to the left of equilibrium place, as in figure 3.3 ( degree Celsius ) , x is negative and F is positive, bespeaking that the way the force is to the right. Of class, when ten = 0, as in figure 3.3 ( B ) , the spring is unstretched and F =0. Because the spring force ever acts toward the equilibrium place, it is some clip called a restoring force. A reconstructing force ever pushes or pulls the object toward the equilibrium place. The procedure is so repeated, and the object continues to hover back and Forth over the same way. This type of gesture is called simple harmonic gesture. Simple harmonic gesture occurs when the net force along the way of gesture obeys Hooke ‘s jurisprudence – When the net force is relative to the supplanting from the equilibrium point and is ever directed toward the equilibrium point. Figure 3.3: The force exerted by a spring on an object varies with the supplanting of the object from the equilibrium place, x=0. ( a ) When ten is positive ( the spring is stretched ) . ( B ) When ten is zero ( the spring is unstretched ) , the spring force is zero, ( degree Celsius ) When ten is negative ( the spring is compressed ) , the spring force is to the right.DecisionAs my decision, Newton ‘s jurisprudence was a really utile in presents because it is can utilize the 3 type of jurisprudence to forestall any accidents in now coevals. First ‘s jurisprudence is provinces that a force must be applied to an object in order to alter its speed. Second ‘s jurisprudence is acceration of an object is straight relative to the net force moving on it and is reciprocally relative to its mass. Third ‘s jurisprudence is whenever we push on something, it pushes back with equal force in the opposite way. Second, harmonic oscillation is a type of forced and damped oscillation that is amplitude of a existent vacillation pendulum or hovering spring lessening easy with clip until the oscillation stop wholly. This decay of amplitude as a map of clip is called damping.

Communications Essay

1. What is an implication, in general, and what are specific implications of the presence of the U.S. flag, Constitution, and Bill Of Rights in all the classrooms at the University of Arizona? a. A general definition of an implication is an assumption that can be inferred from a given scenario that is not obviously specified. The US flag, Constitution, and Bill of Rights are all important symbols of freedom in the United States. The Bill of Rights contains the first ten amendments to the Constitution that preserve the liberties and freedoms prevalent in the United States. The Constitution sets forth the structure of the government we created after rebelling against the British monarchy. The US flag contains a representation of the original 13 colonies that rebelled against the British monarchy as the stripes and the current 50 states as the stars, this representation holds a strong symbol of Americanism. A specific implication of having the U.S. flag, Constitution and Bill of Rights in all University of Arizona classrooms is to help remind students of the freedoms that are available to them in the United States. These symbols of personal freedom promote one’s ability to be an outspoken individual, go against the grain in everything they do, and maintain an individual spirit. 2. Problems in business, government, and relationships are frequently blamed on a lack of communication or a failure to communicate properly. Use the Tubbs communication model on page 9 of your Human Communication textbook to diagnose a communication problem and suggest a recommendation for fixing the problem. a. Tubbs’ communication model involves two communicators and contains three main components of communication: the messages, interference, and the channel. Communication problems can exist across all three components of Tubbs’ communication model. Messages can be intentional and unintentional, when we send an unintentional message we give a message that we didn’t intend to and will usually not find out about the error until we receive feedback from the receiver. Communication problems in channels can occur when sending a message through the wrong channel, each channel serves a primary purpose and sending the wrong message through a channel can lead to a breakdown in communication. Interference is what causes a sent message to become misunderstood or missed completely, usually due to a distortion in the message or the receiver becoming distracted. A fairly common problem that has become more prominent in communication since the rise in popularity of electronic messaging is the inability to relate sarcasm, irony, or other emotions effectively. Usually when someone says something sarcastic it can be taken as a serious statement and the receiver can view the sender as ignorant or senseless. To fix this the person either has to relate the message through a more emotionally efficient channel, such as a telephone call, or include a signifier that allows the person to realize the text should be taken as sarcasm, such as including the tag /sarcasm afterwards. 3. What subject matter is at the heart of the field of communication? To answer this question, imagine that a friend or family member asked you what ‘communication’ as an academic subject was about. How would you respond to that person so that they had a clear understanding? a. Communication has changed a great deal over the last 2400 years but has always maintained a primary center to its study while adding more and more elements. In ancient Greece, Socrates and Plato used communication (then called Rhetoric) as a means to discover the truth and draw it out of their students. Aristotle took Plato’s view and expanded onto it that truth is not always absolute and humans must therefore ascertain the â€Å"probable† truth. These early understandings still hold relevant today and create a framework for the contemporary study of human communication. At the heart of communication is the need for understanding, the need for people to be able to help others understand what they’re saying and understand what others are saying. With this need for understanding Plato stated that rhetoric would be used to promote falsehood over truth while Aristotle saw that either falsehood or truth could be promoted and it is the duty of the citizen to use rhetoric to defend the truth. Communication covers the central topic of providing information to other people through multiple channels in an efficient and effective manner. As communication progresses it will continue to hold its central subject matter while adding more and more relevant areas of interpretation. 4. How was the ancient Greek city-state of Athens involved in the history of communication? What connections exist between communication in ancient Athens and communication in the world today? a. Athens was home to the three scholars who created the two primary views to what we currently know as communication. Socrates, Aristotle and Plato provided a strong foundation for the study of communication while coming from two different views of rhetoric. Socrates and Plato were credited to creating the view of â€Å"Divine Truth† which sought to use reasoning and dialogue to â€Å"draw out† knowledge and understanding. Where as, Aristotle viewed that truth is all around in the environment and must be taken in through the senses. Much of what Socrates, Aristotle and Plato put into communication (rhetoric) is still valid today; Aristotle stated communication is â€Å"purposive† and can be evaluated on whether they accomplish their purpose. Socrates demonstrated a strong relationship between communication that would result in the discovery and appreciation of truth and beauty; this gave a precedent to the value of ethics in communication. Each view puts value into a different way of viewing the truth that surrounds us every day; one sees that there is truth in everything and it’s up to the individual to find that truth while the other views that truth is dependent on the person and can change depending on a persons view. These two views from ancient Athens will continue to lead the study of communication and help shape the continued understanding of the field.

HEALTH LAW AND ETHICS - Essay Example h traditional organization in the system leaves a question mark to many people since a lot has changed as far as labor systems, technology and introduction of new scientific inventions. Most Americans are well alert of the many hardship with the current national health care system compared to a decade ago. Lack of access to inexpensive health insurance and the rising of health care is of prodigious concern to many American citizens (Kronenfeld 70). Unlike before, any working families fear getting sick or injured since they cannot afford basic health care or health insurance (Kronenfeld 59). Many individuals get turned away from insurance firms because of pre - existing medical conditions or illnesses. Others lose their health insurance after they change their jobs or get laid off from work. The cost of health care and health insurance is rising at a rate faster than inflation and wages. According to a study by Kaiser Family Foundation, carried out from 2000 to 2006, wages increased 3.8%, the general inflation rate increased 3.5%, while health care premiums increased 86% (Kronenfeld 46). Most of the uninsured comprise of working Americans who cannot manage to afford the health insurance cost. It is evident that these health hardships faced today did not exist in the earlier

The law discourage activities that would likely cause accidents. These includes, over speeding and careless driving, misuse of warning lights to indicate a form of danger especially when a dignitary is on a special trip of high importance that requires punctuality; the police officers transporting Jimmy Barner and the band pretended to be an important group of government officials late for an urgent meeting. Despite having come from the airport, the legendary Cold Chisel Rock band was not supposed to use government vehicles; any government property is subject to questions when used outside the required obligations. The taxes that are involved in the management and maintenance of the government owned properties including vehicles are sourced from taxes remitted by the common man. The police officers breached the laws governing government properties (Gans 2012). While not on an official duty, the police officers were not supposed to drive with emergency hazards lights on. The speed limits were to be observed, like any other passenger or private vehicle on the specified road (Church 2009). Law that governs property is based on the ownership of such properties. Government property is different from personal property hence should be handled with due respect. Any state property should be handled within the state laws of property management; hence the officers should have faced more charges for allegedly mishandling government vehicles. The police assisted unauthorized users to not only travel in the government vehicles, but also to gain security from public properties (Gans 2012). Since there is no link or contract between the Australian legendary Cold Chisel Rock band that would enable them to ride in state owned vehicles, the legendary Cold Chisel Rock group also committed an offence as they did not use

Financial Modeling Essay Example | Topics and Well Written Essays - 750 words

Financial Modeling - Essay Example It has been argued that this economic turmoil has rendered portfolio management theories irrelevant. This paper explores this assertion. Recent Upheavals in World Financial Markets The global financial crisis of the 21st century has been described as the greatest economic and financial crisis the world has seen since the Great Depression of the 1930s (Ciro 2012). This economic turmoil, unlike the 1930s depression, caught many by surprise. Governments, investors, and the knowledgeable and sophisticated market participants were caught unawares by the speed and intensity of the economic decline. The international credit and financial markets were disrupted and dislocated by this financial crisis especially in 2008 and 2009. Governments in response to this economic crisis came up with policy and fallout responses from 2009 and 2011. These responses to some extent have rendered portfolio management theories irrelevant. Why Portfolio Management Theories Have Become Irrelevant Portfolio man agement theories are two; portfolio theory and capital market theory. ... Brentani (2004) on the other hand defines capital market theory as dealing with the effects of investor decisions on security prices. This theory shows the relationship that should exist between risk and security returns if investors constructed portfolios as specified by portfolio theory. Markowitz (1952) asserts that the process of selecting portfolios is divided into two stages; observation and experience, and beliefs about the future performance of available securities. The impact of the financial crisis disrupted the forecasts on future performance of available securities as asserted by the portfolio theory. According to Ciro (2012), the financial crisis forced most of the banks and lenders to shut their doors as investments in the stocks markets declined drastically. This aspect made the application of forecast facet of portfolio theory difficult. King (1966) basing his argument on the 1930’s financial meltdown and the random-walk theory, claims that this upheaval has se en stock prices move together. Portfolio theory assumes that investors will choose investments that have the lowest amount of risks whenever they are presented with the same level of expected returns. Fama and French (2002) argue that investors will seek to maximize their utility basing the decision to invest on investment’s risk and return. Apparently, the financial slowdown increased the risk levels and as such it was expected that investment rates may fall. This did not happen as expected. According to Amenc and Martellini (2011), this market turbulence has also impacted the wealth levels around the globe negatively and led to doubts about the value added by professional managers by the institutional investors. According to Statman (1987),

The importance of peer relationships for children social development Essay

The importance of peer relationships for children social development - Essay Example Social development entails continued enhancement of skills relevant to help ones interact with the immediate social environment consisting of people and prevailing conditions and situations. The peer relationships development in children is aided by the combined role played by parents, practitioners as well as the attitudes of the children being taught. Moreover, peer relationships create a sense of responsibility in children, eradication of loneliness caused by family troubles, as well as the enhancement of social competence. These are rationales to the development of social development in an individual. Many problems in children are as a result of poor social upbringing, which ultimately leads to the withdrawal of some children from their peers. However, the recent years have seen researchers, scholars, as well as academicians getting actively involved in the study of the effects of peer relationships in human life (Ford and Harris, 1999). The discussion in this paper aims at inves tigating into the importance of peer relationships in social development. The role of practitioners is crucial to establish at this juncture, as well as the key elements of peer relationships to enhance a better understanding. The reasons as to why children withdraw from their peers as well as the rationale of peer relationships in the future life of children will also be established. Key elements of peer relationships Peer relationships are attributed to a number of significant elements, which include self/irritability, family, school and peers as well as work. Self/ irritability element determines the response of distinct individuals to occurrences/ phenomenon. Some children who are faced with difficulties resulting from physical, family troubles, abandonment, resiliency, and exceptionality respond slowly to peer-relationships. In contrast, those in the relevant contexts often demonstrate a quick response to the peer relationships. Secondly, family context plays a pivotal role in the performance of a child in the social realms. Bronfenbrenner’s systems refer this as the main micro-system influence (Siegel, 2008). Mesosystems explain the influence that occurs as a result of how children respond to the immediate environments, which are composed of a connection between any of the two micro-systems. For instance, a connection between family and school, a child who has difficulties in family life will definitely have difficulties interacting with teachers as well as other children. Recent research has indicated teachers as contributors of poor peer relationships due to their utilization of favoritism on some children. The same is impacted in the societal set up since the child has already developed a negative attitude. Peers are also long-term rationales for the extents of peer relationships and finally social development. These are the friends that one has to interact with in all contexts. Harsh treatment by some peers is also a major cause of withdrawal. Some peers also result in poor

Film Music Essay Example | Topics and Well Written Essays - 2500 words

Film Music - Essay Example The difficulty of studying the nature of the music for motion pictures derives from the complexity of the medium. Films usually operate through "a conjunction of visual and auditory signals, research into film music requires an understanding of not one but two non-verbal systems of communication, as well as the problematical jargons with which we attempt to describe each of them in speech (Marks, 1997, p. 3)". Currently, few scholars have mastered the field of such specialized studies as music in silent movies. Thus, I have to address that this paper has limitation based on the narrow specialization of the topic. The subject of film music is neglected by researchers, because it spans between two disciplines and its material presents many problems (Marks, 1997). Unlike concert music, film music exists only as an accompaniment to the film and is not included into a repertoire. Especially in music for silent movies, the primary material that has to be researched is not the music, but th e film itself. Consequently, the film music in silent movies has to be studies together with a profound observation of the movie. Music in this sense is in the core of the research and the movie plot stays in the periphery (Marks, 1997). "As we view a film, our minds must contend with the ever-changing content of the moving image and the soundtrack. The individual elements (not just music, but also lighting, camera work, editing, and so forth) are submerged into the flow of images on the screen. Hence the engrossed audience rarely perceives these elements consciously; it is simply carried along by the stream of sights and sounds (Marks, 1997, p.4)." Marks (1997) points out that most of our "information about music and silent cinema dates from after 1910; earlier than that, documents are lacking and extant scores are few (p. 26)." Altman (1998) observes that in the early periods of silent film musical accompaniment was not standard practice. He explains that the US film industry began to introduce normative musical score as accompaniment between 1908 and 1912. Altman (1998) also notes that developing the musical accompaniment was a significant part of the cinematic transformation that was taking part at that time. Efforts were made to stimulate the use of film music and to supervise its quality. Much more attention should be paid on the impact of geography into music. The urbanized east coast versus the less populated western states, the neighborhood trends versus the downtown surroundings have influenced the sound in the silent movies (Altman, 1998). Ethnicity and race and the emergence of African folklore traditions, ragtime an d jazz on the musical accompaniment also placed a cornerstone in silent movies music. After the World War I and the disastrous flu epidemic in the 1918, the 1920s can be characterized as one of the most prosperous years in America. The 1920s are also called "The Roaring Twenties" or "The Jazz Age" (Blundell, n.d). After the World War I, a lot of African Americans who were living in the South, started to move North. Northern America was more industrialized and provided more employment opportunities. Thus, African Americans hoped they could make a better living. 1920s was the time when

The Main Target Market of the Innovative Foamed Doom Case Study

The Main Target Market of the Innovative Foamed Doom - Case Study Example In the year 2008, there were around 7,73,600 construction companies in the United States (AGC of America, 2011). All of these stats indicate that there potential and growth opportunity in the industry. The new concept of the foamed dome and other structures can be marketed to a considerably large target market. The target market for the new product of foamed dome is large, however, the company will have to clearly identify the need and requirements of the market. The constructors and architects are in search of more environmentally friendly and inexpensive construction material. Different companies and firms are coming up with several innovative products and construction material in order to make the construction industry more sustainable (Miller, 2011). Apart from this, due to the recent economic crunch architects and constructors are looking for cost-saving solutions. The new and innovative product being introduced by the company will be able to cater to all these changing needs of the target market. It is important to establish Point of Parity (POP) for any brand in order to make sure that the product or brand can be related to other products and competitors in the industry. This, in turn, allows the customers to establish the basic understanding and a point of reference. The Point of Parity (POP) in this case is that the foam dome is also used in the construction of different buildings and structures like other constructing material. Once the Point of Parity (POP) has been created, the next step for the brand is the creation of the Point of Difference (POD). It is important to create a Point of Difference (POD) for a brand so that the customers are able to differentiate it from other products in the market.

Can Alkaline Diets Prevent Cancer Research Paper

Can Alkaline Diets Prevent Cancer - Research Paper Example Amid the rising cases of cancer, the main question is; what actually went wrong after the widespread industrial revolution that cancer and other degenerative diseases have become close components of human life? The answer could be very simple; our eating habits. Before the advent of industrial revolution, human beings survived on natural food substances with balanced amount of minerals that boosted the body immune system as well as performing detoxification. Today, because of industrialization we embrace consumption of processed foods rather than the natural diets. Going by the evident trend in the manner in which cancer spreads today or simply comparing and contrasting the lifestyles of agrarian periods and the current industrial periods, it is determinate that consumption of natural food is the surest way of preventing cancer (Earl 292). In this case, natural foods are considered as food substances rich in alkaline or high pH values. The main alkaline food substances are citrus fruits, fresh vegetables, nuts, legumes and seeds. Alkaline food substances do not encompass substances like grains, excess salt, excess dairy products or meat. Earl states that alkaline food substances play a significant role in ensuring preventing an individual from developing cancerous cells (292). It is however not stated that an individual should not consume acidic food substances, but at regulated low amount. This is because acid is usually required for digestion purposes in the stomach but should always be at the pH of 1.3-1.75. In order to fight cancerous cells, blood and not the stomach requires a high alkalinity level, pH of 7.34-7.46. The reason why a high proportion of acid is never essential for the body is because it results to the development of toxins that suppress the body immune system thereby inhibiting cells from absorbing oxygen. Further accumulation of acid and inhibited supply of oxygen lays ground for

Existentialism in Literature Essay Example for Free

Existentialism in Literature Essay Existentialism in literature is a movement or tendency that emphasizes individual existence, freedom, and choice. While Existentialism was never an organized literary movement, the tenets of this philosophy have influenced many diverse writers around the world and readers can detect existential elements in their fiction. Americans writers like William Faulkner, Ernest Hemingway and John Steinbeck reveal existential elements in their writing. Perhaps the most prominent theme in existentialist writing is that of choice. Humanitys primary distinction, in the view of most existentialists, is the freedom to choose. Because we are free to choose our own paths, existentialists have argued, we must accept the risk and responsibility of following our commitments wherever they lead. American writers Henry David Thoreau and Ralph Waldo Emerson often wrote about these concepts. Existentialism is not dark. It is not depressing. Existentialism is about life. Existentialists believe in living—and in fighting for life. The politics of existentialist writers around the world varies widely, but each seeks the most individual freedom for people within a society. Despite encompassing this wide range of philosophical, religious, and political ideologies, the underlying concepts of existentialism are constant: ? Mankind has free will ? Life is a series of choices ? Few decisions are without any negative consequences ? Some events and occurrences are irrational or absurd, without explanation. ? If one makes a decision, he or she must follow through. So existentialism, broadly defined, is a set of philosophical systems concerned with free will, choice, and personal responsibility. Because we make choices based on our experiences, beliefs, and biases, those choices are unique to us—and made without an objective form of truth. There are no â€Å"universal† guidelines for most decisions, existentialists believe. Even trusting science is often a â€Å"leap of faith. † The existentialists conclude that human choice is subjective, because individuals finally must make their own choices without help from such external standards as laws, ethical rules, or traditions. Because individuals make their own choices, they are free; but because they freely choose, they are completely responsible for their choices. The existentialists emphasize that freedom is necessarily accompanied by responsibility. Furthermore, since individuals are forced to choose for themselves, they have their freedom—and therefore their responsibility—thrust upon them. They are â€Å"condemned to be free. † Many existentialist writers stress the importance of passionate individual action in deciding questions of both personal morality and truth. Personal experience and acting on ones own convictions are essential in arriving at the truth. 17th-century French philosopher and existentialist Blaise Pascal saw human existence in terms of paradoxes. He believed that â€Å"We know truth, not only by reason, but also by the heart. † And as many existentialists, he acknowledges that â€Å"It is the fight alone that pleases us, not the victory. † The modern adage that the journey is more important than the final destination applies to this idea. Danish philosopher Soren Kierkegaard, who was the first writer to call himself existential, reacted against traditional thoughts by insisting that the highest good for the individual is to find his or her own unique vocation. As he wrote in his journal, â€Å"I must find a truth that is true for me . . . the idea for which I can live or die. † Existentialists have argued that no objective, rational basis can be found for moral decisions. The 19th-century German philosopher, Friedrich Nietzsche contended that the individual using free will must decide which situations are to count as moral situations. He believed that â€Å"There are no facts, only interpretations. † . . . and he is famous for this well known adage:â€Å"That which does not kill me, makes me stronger. † The 19th-century Russian novelist Fyodor Dostoyevsky is probably the most well-known existentialist literary figure. In his book Notes from the Underground the alienated anti-hero questions experiences in life that are unpredictable and sometimes self-destructive. French writer, Jean Paul Sartre wrote that man can will nothing unless he has first understood that he must count on no one but himself; that he is alone, abandoned on earth in the midst of his infinite responsibilities, without help, with no other aim than the one he sets himself, with no other destiny than the one he forges for himself on this earth. There is no ultimate meaning or purpose inherent in human life; in this sense life is absurd. We are forlorn, abandoned in the world to look after ourselves completely. The only foundation for values is human freedom, and that there can be no external or objective justification for the values anyone chooses to adopt. † When the Swedish Academy granted the Nobel Prize in Literature to Sartre for his work which, they recognized as â€Å"rich in ideas and filled with the spirit of freedom and the quest for truth, [that] has exerted a far-reaching influence on our age,† Sartre made it known that he did not wish to accept the prize. In a public announcement, in1964, Sartre expressed his regret that his refusal of the prize had given rise to a scandal, and he wished it to be known that his refusal was not meant to slight the Swedish Academy but was rather based on personal and objective reasons. Sartre pointed out that due to his conception of the writers task he had always declined official honors so this act was not unprecedented. He had similarly refused other awards offered to him. He stated that a writers acceptance of such an honor would be to associate his personal commitments with the awarding institution, and that, above all, a writer should not allow himself to be turned into an institution.

Tell Tale Heart and the Lotter Essay Example for Free

Tell Tale Heart and the Lotter Essay American writer Henry James believed characters are only as interesting as their responses to particular situations. The statement he made can be supported by many pieces of literature that we have encountered. The way a character reacts to the situation they are placed in can tell a lot about their true character. Two characters were placed in different situations in â€Å"The Tell-Tale Heart† written Edgar Allan Poe and The Lottery written by Shirley Jackson reactions will be discussed in this essay. In â€Å"The Tell-Tale Heart† the tenant thought he would get away with the murder he had, but committed cracked under the pressure. Initially when the police offers entered the home he was he was able to keep his composure, but he slowly started to break. My head ached, and I fancied a ringing in my ears: but still they sat and still chatted. The ringing became more distinct:—it continued and became more distinct: I talked more freely to get rid of the feeling: but it continued and gained definitiveness—until, at length, I found that the noise was not within my ears. (Poe 390) At this point the man started to hear things in his mind. He was imagining the beating of the old man’s heart. Prior to his delusion the reader probably believed he would get away with the murder. Finally the man can no longer take the sound of the old man’s heart beating beneath the floor boards. â€Å"Villains!† I shrieked, â€Å"dissemble no more! I admit the deed!—tear up the planks!—here, here!—it is the beating of his hideous heart!† (Poe 391) I believe he told the officers about the old man’s body because his conscience got to him. If he was like most cold, blooded killers his conscience would not have told him he had done something wrong. In â€Å"The Lottery† when the Hutchinson family initially draws the piece of paper from the old black box, Tessie continually pleads to do the redo the drawing of the names. She says, You didnt give him time enough to take any paper he wanted. I saw you. It wasnt fair!(Jackson 267). Even though the drawing of her family’s name was done completely fair she tries to come up with some excuse. Even though her whole family, including her children, initially had the potential to be stoned she was the only one who wanted a redrawing done. When Tessie’s realized she had the paper she did not even try to say goodbye to her family. Most people, even criminals today, would rather spend their last moments saying goodbye to their loved ones. Tessie on the other hand continually said, It isnt fair, it isnt right(Jackson 269). With her continually saying this isn’t fair or right this shows she does not believe in the system her town used. When she first got to the lottery she made a joke about leaving the dishes, as if she was okay with what was about to take place. When her family’s name was drawn her true feeling were shown. She obviously did not agree with having a human sacrifice in order to better her town’s chances of having a good harvest. Both the man from and Tessie were placed in some an extremely tense situation, and both reacted in a similar manner. The man cracked under the pressure of killing the old man and Tessie Hutchinson lost her composure when she found out she was the one who would be stoned. Henry James quote of â€Å"characters are only as interesting as their responses to particular situations† was confirmed from the above reading because both of the characters show a different, more interesting, side of themselves when they faced with a predicament.

Prostate Cancer Causes And Treatment Health And Social Care Essay

Prostate Cancer Causes And Treatment Health And Social Care Essay This paper will investigate several different academic journal articles and some popular media articles that are about prostate cancer. These articles discuss prostate cancer causes, (hypothetical and known), detection methods, and treatment options. A couple of the articles also focus on the cost of treatment for patients, as well as the risks involved with the differing methods of treatment. Several treatment options for prostate cancer are still being studied. This essay will critically analyze and compare prostate cancer detection methods, (such as Prostate-specific antigen or (PSA) tests) treatment options, and the differing success or failure of each method, as well as focusing on the increasing cost of treatment that patients are forced to pay. Some of the articles also suggest that more resources and more education are needed to help lower the mortality rate from prostate cancer. This paper will explore what is being done to help lower the mortality rate as well as what is be ing done to help increase the rate of early detection of prostate cancer. Keywords: Prostate-specific antigen Prostate Cancer: Causes and Treatment Options Available in Todays Scientifically Advanced Society According to the Prostate Cancer Foundation, prostate cancer occurs when cells within the prostate grow uncontrollably, creating small tumors. The term cancer refers to a condition in which the regulation of cell growth is lost and cells grow uncontrollably. Prostate cancer is a disease of epidemic proportions. 1 in 6 American men will be diagnosed with prostate cancer and new cases are diagnosed every 2.7 minutes (Charles 2009). As prostate cancer poses such a threat to men worldwide, more time and money should be spent to improve upon the existing methods and technology as well as invested towards education and awareness programs. The fact that these statistics are real is why prostate cancer awareness and education is so essential because many deaths could have been prevented if the cases had been detected at earlier stages of the cancer. Prostate cancers specific cause is still unknown, however scientists hypothesize that genes play a role, because the risk factor for getting pro state cancer is substantially higher if you have a family history of it. The two main methods used for prostate cancer screening are rectal examinations and prostate-specific antigen (PSA) blood testing. Rathus, Nevid, and Rathus (2008) remind men 50 years and older that the American Cancer Society recommends that men receive annual rectal examinations and PSA blood tests. Treatment methods for prostate cancer are limited, but new technology has allowed for a higher survival rate because of early detection. The first point of interest is that the costs of prostate cancer treatment have gone up substantially in the last 20 years according to USA Today reporter Lisa Szabo. In her article entitled Patients bear brunt as cancer spending hits $90 billion she discusses how these rising costs have been driven by forces such as new drugs, robotic surgeries, and radiation techniques (2010). In her findings she discovered that from 1991 to 2002 the cost of treatment for cancer doubled. These increases are unsustainable claims John Seffrin, CEO of the American Cancer Society. Because of the increasing costs of treatment the American Cancer society can only help 1 out of 6 patients as opposed to in the past when they were able to help 1 in 5. When one takes into account how many cancer patients are in the United States, then they can realize how many people are forgoing treatment because they are uninsured and cannot afford treatment. It is tragic that the rising costs are resulting in preventable deaths. In another article reviewed, Krahn, Zagorski, Laporte, Alibhai, Bremner, Tomlinson, Warde, and Naglie, (2009) set out to discover healthcare costs in relation to prostate cancer. They researched direct medical costs for around 42,000 men over the progression of the disease. The costs they found were between $2,000 to around $16,000 dependent on where the individual patient was in the treatment process and how advanced their cancer was. The resulting conclusion was that prostate cancer costs are highest around two events, cancer diagnosis and cancer death (Krahn et als. 2009). The second point of interest is that drug company Roches Avastin a prostate cancer drug recently hit headlines and not in a good way. According to the Wall Street Journal, Roche Holdings released a statement that said that Avastin had failed in late stage prostate cancer trials. This news was not good for stockholders who are estimated to have lost projected sales of 7.48 billion dollars. The other bad news is that people who have been using Avastin an antibody for treatment of cancer, are also paying for something that is not as effective as they have been lead to believe. The third point of interest is that although scientists know what causes cancer, new steps are being made to discovering what specifically causes prostate cancer, and other types of cancer. In an exciting article in Science News, author L. Sanders reviews a new study that suggests probable links between self-renewing stem cells and prostate cancer (2010). The study suggests that genes are the culprit. Think about cancer as a disease of stem cells, Mutations in these cells can cause normal stem cells to lose their regularized behavior and instead turn into an incipient cancer (Sanders 2010). The researchers also found that prostate tissue cells called Basal stem cells are the most likely culprit in laboratory tests done on mice. In all the research they have done, Basal stem cells are what drives the cancer, regardless of the type of mutation says Owen Witte, a researcher at the University of California. A specific gene called Bmi-1 plays a significant role in Basal stem cells renewal process, when Bmi-1 activity was reduced, the cells were no longer able to self renew, nor did they form tumors (Sanders 2010). The fourth point of interest is that studies show family history of prostate cancer as one of the leading risk factors associated with prostate cancer. As Damber and Aus (2008) discovered while researching prostate cancer, family history is a large factor when assessing ones individual risk factors. They hypothesize that one apparent reason for this is that genes are passed down biologically from father to son. They also believe that the cancer causing genes mutate, but the reason(s) why are still unknown. According to the textbook authors, Rathus, Nevid, and Rathus (2008) consuming high amounts of animal fats has been shown to increase ones risk of getting prostate cancer. They also discuss how the chances are higher in black males than in white males. One thing Damber and Aus (2008) did note in their study was that the number of cases of prostate cancer was higher in men in urbanized nations as opposed to Asian men. The resulting studies showed that lifestyle differences as well as exposure to radiation were the reasons for the different statistics between Asian men and those in more urbanized nations. They also discuss how PSA and other screening methods are still being studied too analyze just how effective they actually are. Once men are suspected of having prostate cancer, the most common method of diagnosis is a biopsy which is surgically removing a small portion of the suspected tumor for testing. Most patients once they are diagnosed with the disease, are concerned with how concentrated the cancer is, because it is this factor more than any other that determines how long they have to live. In other words, the disease establishes the prognosis more than the choice of treatment. (Damber and Aus 2008) Treatment methods are varied and all have risks involved, but as the authors pointed out, most treatment plans are based on factors such as the PSA number, (how high or low) the level is, the size and placement of the tumor, as well as the patients individua l life expectancy. Treatment plans also vary depending on if the cancer is localized to just the prostate, or if it has advanced (grown) within the prostate, or if the cancerous cells have spread to other parts of the body more serious treatment options will be considered. Damber and Aus (2008) theorize that treatment methods for both localized and advanced prostate cancer will remain the same for the time being. The fifth point of interest is the actual treatment procedures that are currently used. According to K. Charles in her article about prostate cancer in the Daily News, NY, she discusses the three major ways to treat prostate cancer. Surgery, external beam radiation, and radioactive seed implant therapy. A fourth new and radical treatment option is known as active survellaince, which is basically doing nothing but constantly monitoring the cancer. She discusses in her article that doctors have not yet been able to decide which treatment option is more effective than another, as they say that the results of each treatment option vary case to case. These variants also depend on how progressed the cancer is and how healthy the patient was before they got cancer. The sixth point of interest is a possible prostate cancer treatment that is still being researched called Cryotherapy. In an article by A. Gardner, she discusses how several prostate cancer patients had successful cryoblation and their tumors were successfully thwarted. The method is still in research however, and as Dr Debra Monticciolo said, The concept is good, but we need a bigger study with longer follow up. It takes a while for a couple of tumor cells left behind to gather enough steam to be noticed (Gardner 2010). One of the most controversial methods of treatment is to do nothing and just check in on the cancer frequently, to ensure that it has not grown or spread. In an article by Johnsun and Treurnicht, they claim that, The majority of men with low-risk prostate cancer will die of unrelated causes (2009). They also discuss how this newer method of treatment, officially known as active surveillance challenges the old method of radiation, and instead theorizes that attentive non-action, with only minimal treatments is possibly more effective. Johnsun and Treurnicht researched a group of 549 cancer patients who were offered active surveillance or surgery. The patients chose the surgery. Over an 8 year time span, it was discovered that the only way to ensure if active surveillance is an effective method of treatment is by repeated studies of men who have had biopsies. In another article I reviewed, author R. Lane and C. Metcalfe looked into a study that is being conducted in the UK. The study is a randomized controlled trial evaluating different prostate cancer treatments (2008). In the article, they claim that repeat PSA testing is one of the most effective methods for deciding if one needs surgery. According to the article, men whose PSA levels are between 3.0 and 19.99 ng/mL are all candidates for treatment and most likely, a biopsy. Also according to Lane and Metcalfe, in the trial referred to in the article, the participants were between 50 and 70 years old. The conclusions of the authors was that repeat PSA blood testing, particularly in men aged The seventh point of interest in regards to Prostate Cancer detection methods is the conflict over PSA testing and its accurate results, or is it as accurate as one would hope? Nogueira, Corradi, and Eastham (2009) explore other biomarkers besides PSA tests. They believe that although PSA is the best cancer biomarker available, it is not perfect. It lacks both the sensitivity and specificity to accurately detect the presence of prostate cancer (Nogueira et al., 2009). In their article, they evaluate the progress that is being made towards being able to use newly discovered biomarkers to help screen for prostate cancer. The studies that they review show that Human Kallikrein 2 or (hK2) is a serine protease that is closely related to PSA in sequence. The studies have revealed however, that (hK2) is not ready to be used yet as it can indicate that there are cancer cells active in the blood, but not accurately enough. This is similar to the problem that researchers run into with PSA test ing. Several other membrane antigens and antibodies are also being studied, but none of them are yet ready to be used as further research and testing is still needed. In the textbook, Rathus, Nevid, and Rathus (2008) agree with this article that PSA testing is the best method available. This should not be seen as though no progress has been made however, because as Dr. Richard Stock said, The past 40 years have seen a revolution in prostate cancer treatment. Not only are 90% of cases caught before they metastasize, but doctors have vastly improved technology for fighting cancer in the other 10% of patients (Charles 2009). The eighth point of interest is the recent news that the American Cancer Society has released new guidelines on prostate cancer screenings. In the article by A. Gardner, it discusses how the American Cancer Society is now putting less emphasis on routine PSA testing and more emphasis on doctor-patient conversations and decisions. These new guidelines are issued as a result of research and the ongoing conflict over how accurate PSA testing really is. According to a statement issued by the American Cancer Society, men with no symptoms of prostate cancer who are in relatively good health and can expect to live another 10 years should make an informed decision with their doctor about prostate cancer screening after learning the uncertainties, risks, and potential benefits associated with such screening (Gardner 2010). These new statements disagree with with what Rathus, Nevid, and Rathus (2008), state in the textbook, The American Cancer Society recommends that men receive annual digital rectal examinations beginning at the same age as PSA tests (Rathus et al. 2008). They are now suggesting that PSA testing should not be a requirement for all men over 50. The ninth point of interest, however, is that many agree that PSA testing is still not a very reliable or effective method of detection. In an article in Practical Nurse, urologist Professor Roger Kirby, director of the Prostate Centre in London, states that, PSA testing is hugely controversial because the number of false positives and missed diagnoses of prostate cancer generated by the test raises questions about its usefulness (2009). In the article Kirby also points out that although PSA testing is so sketchy, that unfortunately men do not have many other options for detection. He calls for more research into alternative testing methods for the presence of cancerous cells in ones blood. He also calls for more education among men, to make them aware of their risk of contracting prostate cancer. Personal education and personal awareness are key elements in fighting the mortality rate of prostate cancer. The tenth point of interest is the progress being made towards educating the public on prostate cancer. In the European Journal of Cancer Care, contributing author S. Bowen, discusses a public health program in Ireland called the National Cancer Information Service. It was developed because of the National Cancer Forums, concern that high quality, accurate information and resources should be available to the public (Bowen 2010). The majority of people who called in to the service concerned about prostate cancer were men in their 50s to mid 60s. The service also found that most men were calling to find out how and where to get screened for prostate cancer. Bowen thinks this is due to not enough public awareness of prostate cancer, he believes that, as the public becomes increasingly aware of cancer, it is important that they have access to clear unbiased information from a responsible quality service informed by ongoing evaluation (2010). Overall, the popular media articles that I reviewed did seem to agree with the academic journal articles. In regards to the cost of prostate cancer treatment, the textbook did not really go into depth on the topic, but the two articles that I reviewed did seem to agree with the consensus that prostate cancer treatment is expensive, and that the cost of treatment is rising. Another issue that I reviewed was also not really covered by the textbook, but the article that I reviewed was convincing in that it shows that more research is needed for prostate cancer drugs. Another issue that I reviewed was also not covered by the textbook, but I found it fascinating that scientists are coming so close to finding a way to cure cancer. Another issue I reviewed was agreed upon in my textbook, the academic article and the popular media that risk factors for prostate cancer are pretty consistent. Another issue that I reviewed was the actual procedures which did agree with my textbook. Another issu e I reviewed was Cryotherapy, which is an experimental method, not covered in the textbook. Another issue was conflict over PSA testing, and I found that the academic and popular media did agree mainly when it came to this issue. I do not feel that anything was left out in these articles or the textbook. I did feel that the academic studies were and are legitimate. I believe that future studies should focus on prostate cancer detection and treatment. The articles that I reviewed were very promising as they show that a lot of progress has already been made in reference to prostate cancer treatment and detection. I think that scientists and researchers should continue what they are doing, especially with the research on stem cells and their direct connections to cancer. I think that finding the cause of prostate cancer should be the number one priority of researchers. I also feel that finding the future cure to cancer can only be done if much more extensive stem cell and gene research is conducted. Until that cure is found howver, I believe it is important to focus todays research on finding more accurate methods of testing, as PSA blood testing has been shown time and time again to not be as reliable as medical professionals would like it to be. The new findings that I discussed are quite exciting though, and the possibility of finding a 100% ac curate test for cancerous cells in the bloodstream is most likely soon to be a reality. The discovery of a new and more accurate testing method for prostate cancer would help increase the number of survivors as well as decrease the number of false readings and wrong diagnoses. I feel that the important message throughout the articles and research that I conducted is that men need to be more educated and more aware of prostate cancer and its symptoms and that doctors need to spend more time with their patients who are diagnosed with prostate cancer. I think that families with a history of prostate cancer need to have father-to-son discussions about prostate cancer and that they might want to cut down on their intake of animal fats and their exposure to radiation as that raises their risk. Black men who consume a lot of red meat with a family history of prostate cancer should be especially concerned. The other important thing is that men who are diagnosed with prostate cancer need to be informed of all their options, not just the options that benefit and are profitable to the medical institution providing the treatment, or the drug company providing the drugs for treatment. The new active surveillance prostate cancer treatment method is still under scrutiny as to whether it is as effective as medical professionals are hoping it will be. I also think that reform is needed in regards to the outrageous cost of treatment, which for the average person, is very hard to afford. The general public needs to be more aware and educated; more societies such as the American Cancer Society are needed to help raise awareness and to provide valuable information, resources, and support to those who are affected. The financial burden on those with prostate cancer is also something that needs to be addressed. The future of prostate cancer is one that is hard to predict however, because cancerous cells and genes are constantly mutating and changing generation from generation. The sheer amount of time, money, and resources that have been put into cancer research and treatments is incredible. I think that the future of prostate cancer will hopefully be cut short by the discovery of a way to prevent the cancerous cells from mutating, whether it is from radiation, antibodies, or removal of the cancerous cells. I also feel that the important message to anyone reading this is personal responsibility and personal awareness and education. It is not groups such as the American Cancer Societys responsibility to educate and help those who are fighting prostate and other forms of cancer, it is the individuals responsibility to do all that they can, within reason, to prevent and detect cancer early, before it is too late. Fear, procrastination, ignorance, and lack of health care and coverage are big issues when it comes down to the truth. The fact of the matter is that many people who are dying and have died from prostate cancer could have been saved if they had detected it earlier. The importance of getting routine screenings for men over 50 years old is crucial. The testing methods may not be 100% accurate, but it is better to be informed than to just take a chance with your life.

Symbolism in The Glass Menagerie :: Glass Menagerie essays

Symbolism in The Glass Menagerie      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The Glass Menagerie uses an extensive pattern of symbolism that describes the characters of Tom,Amanda,Laura and Jim. Glass,light,color and music constitute the substance of the dominant symbols and motifs,serving to reveal deeper aspects of characters and underlying themes of the play.Tennessee Williams wrote the play so that each character had a special symbol which resembled their personality.But he didn't only give the characters of the play a a resembling symbol;he also mentions the apartment blocks to be hivelike conglomerations of cellular living-units resembling a beenstock.The way he describes their location also has a lot of symbolism in its roots because he describes them to be flowering   as warty growths in overcrowded urban centers.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Tennessee Williams used many symbolic aspects to describe Laura and the world she lives in.In the play,Laura represents the very fragile,shy and emotionally crippled girl.In her mind she lives in a world of glass animals and doesn't have a connection to the real world.The managerie of glass also represents the fragile relationships among all the characters.The glass unicorn is most obviously a symbol of Laura-- delicate,sadly different,an anomaly in the modern world.The glass motif recurs throughout the whole play in many other forms.When Laura dropped out of college she constantly visited the zoo,a glass house of tropical flowers that are as vulnerable as she is.During Laura's and Jim's brief romantic encounter,Laura is gaining more confidence about herself.It seems as if she is starting to escape her world of illusions.When they started dancing together,Jim accidently knocked the little glass horse over. Laura,who usually worships her glass collection more than anything else,replied to his excuse;"He's lost his horn.It doesn't matter.Maybe it's a blessing in disguise." and   "I'll just imagine he had an operation.The horn was removed to make him feel less--freakish!Now he will feel more at home with the other horses,the ones who don't have horns....".These two quotes give an impression that Laura is finally escaping her illusive world.She thinks that she might have a chance to survive the real world.What she doesn't know is that she is about to be wounded by the news of Jim's engagement.After Jim tells her the news,she gives him the unicorn as a souvenir and retreats into her land of the glass menagerie never to come out again.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚   In the play,Tom is the adventure seeking man trying to escape the prison Amanda is keeping him trapped in.To escape the real world,Tom constantly goes to the movies.The movies make him think about all the adventures he missing.It his little land of dreams.He is jealous of his father who left his family and achieved what Tom always wanted,

Playstation2 Arrives! :: essays research papers

Playstation2   Ã‚  Ã‚  Ã‚  Ã‚  Late this summer, Sony will release its brainchild product dubbed PlayStation2. This is a follow up to its predecessor PlayStation1. If you are familiar with the video game entertainment market, its usual that a company releases a new console every 4 to 5 years.   Ã‚  Ã‚  Ã‚  Ã‚  The Playstation2 is expected to revolutionize the video gaming industry in ways never imagined before. Who would have thought we would be able to watch DVD's on our video game player? Soon this summer we will be able to. How about connecting to the net and going online to play a buddy or just any competitor in California? Feel like downloading some mp3's? The new PlayStation2 will let you do all these things and more.   Ã‚  Ã‚  Ã‚  Ã‚  PlayStation2 will offer a variety of different ways of using their machine. Not only can you play revolutionizing games, but you can shop through your computer. Sony will offer in 2001 a connection to the Internet in which you can just surf the web. As I have mentioned, Sony has formatted the PlayStation2 to able to play DVD videos along with its games. One of the greatest things about the PlayStation2 is that you can play all your old Playstation1 games on it! Finally! After years and years of this backwards compatibility being in the dark, it is now possible with the PlayStation2. Not only your old games, but even your old controllers, memory cards and wires are going to be fully compatible with the system.   Ã‚  Ã‚  Ã‚  Ã‚  The PlayStation2 is expected to beat out its predecessor in every way including the books. Playstation1 accounted for 40% of all of Sony's profits in 1998. As of the first weekend of sales in Japan, Playstation2 had sold 980,000 units. All in one weekend! The lone fairly new competition that will be on the market before Playstation2 is the Sega Dreamcast. This was released in 1999 and has sold 4 million units since its release. Figure 4 million units in 52-weeks and then look at PlayStation2's numbers in Japan on one weekend.   Ã‚  Ã‚  Ã‚  Ã‚  Playstation2 will be extremely succesful because of it almost cult like following. In a recent study, a conclusion was made that 1 in four homes have a Playstation. That is close to 25 million units sold in the US alone. This all adds up to the 70 million units total sold in the world. And now the product is just more sellable with the DVD, Internet, and backwards compatibility available.

Absolute Monarchism Essay -- essays research papers

The prevailing government of Europe from 1900-century back was absolute monarchism, this form of government worked very well considering the belief of all people in god and the teaching. Monarchist use this belief to justify this rule in. if they could make the people believe that they were ordained position by god then they had no worries because the people belief in god was so prevailing that it was not mentionable in private to go against it. Napoleon and Louis XIV were the ideal rules to use this type of ruling. Napoleon and Louis XIV were the same type of rulers by using the divine right monarchy to control the people of their country, which was France. Napoleon and Louis way of ruling and other similarity were so alike that they could have traded their period when they sat at the throne and the people would have not noticed â€Å"I am the state† Louis famous statement which stated that he was the divine right ruler(R 6). . â€Å"Louis XIV justified his absolutism through the belief that God will it such as a divine right monarch ruled with the authority of god and was beholden to no power except that of god†(R 11). The people of France believe in the faith of god church and their religion that no one dared to defy the divine ruler. Louis was determined to control a nation that was unified politically under his rule and religiously under his faith; Catholicism was to be the only accepted religion for the French people. Louis believe that god had sufficiently appointed him to be...

Overcoming Barriers to Change

The external environment in which businesses operate is continually changing. Businesses must respond to these changes to remain competitive and continue to meet the needs of their customers. They need the commitment and support of key stakeholder groups, such as employees, in order to ensure changes are embedded to shape the organization for the long term. Corus was formed in 1999 when the former British Steel plc merged with the Dutch company, Hoogovens. Corus is now a subsidiary of the Indian-owned Tata Group. Corus has three operating divisions and employs 40,000 people worldwide:Corus Strip Products UK (CSP UK) is based at Port Talbot and Llanwern, Newport in South Wales. CSP UK makes steel in strip form. This is used in markets such as vehicle manufacture, construction, electrical appliances, tubes and packaging. Corus aims to be a leader in the steel industry by providing better products, higher quality customer service and better value for money than its rivals. In 2005 CSP U K introduced a cultural plan for change called ‘The Journey’. The company wanted to address a wide range of business challenges, but the common theme was the fundamental way that people at all levels went about their work.The Journey focused on the values and beliefs of its people. Vitally, this was not limited to employees, but it included contractors, suppliers and other partners. This community of people together re-defined eight core values. These provided the guiding principles by which Corus people would work. By early 2007, all employees had been provided with a booklet outlining the CSP Journey values and the behaviors the company expected them to follow. The new values encourage individuals to be accountable for their actions.For example, previously, there had been tragic accidents on site and other health and safety issues, such as poor driving behaviour. This needed to change. The Journey program has taken a positive approach so that it now steers everything CSP UK does and underpins the culture of the organization. This case study focuses on how Corus Strip Products UK has overcome barriers to change in order to secure a more prosperous future for the business. Reasons for change Organizational change is a planned and ongoing process and follows clearly structured elements:Identify the key drivers for change. These are forces outside and within the organization, for example, the growing strength of competitors (external) or health and safety issues within the organization (internal). Corus employees were encouraged to understand what was happening in the business (the ‘As Is’) and identify any flaws in the existing way of working. Identify the barriers to change. This often involves people’s attitudes. They may want to continue to work as before or cannot see the need for change. Create and implement a plan for change.This focuses on winning the commitment of all employees, identifying specific solutions to problems areas (for example, cutting staff or investing in new systems) and setting out ways of measuring improvement. Employees were encouraged to envision what the ‘To Be’ position for CSP UK looked like and make plans to bring it about. Measure the effectiveness of the change. CSP UK is prepared to make further changes based on the outcomes of the actions. Examples of internal drivers for change (inefficiencies within the business) at CSP UK included: Poor delivery – rather than delivering steel to customers on time there were delays, leading to loss of business. †¢ Competitiveness – steel produced in the UK could be more expensive than from some other countries. †¢ High wastage – failing to make products right first time meant that they had to be reworked or scrapped. †¢ Low staff morale – employees were committed but were not motivated by the environment in which they were carrying out their jobs. External drivers (pressures for c hange outside the business) came from: New competitors – low cost producers in Eastern Europe and the Far East were taking business. This could lead to reduced demand with higher costs. †¢ Changing customer requirements – for example, the fall in demand for steel for the automotive industry meant that Corus needed to find different types of customers or develop different products. †¢ New technology meant customers expected higher specifications. †¢ Perceptions of the steelmaking industry within the community tended to be negative – for example, the industry was seen as having a poor record on environmental issues.Total Quality Management (TQM) initiatives had previously been implemented to great effect at CSP UK to improve productivity and improve competitiveness. CSP UK had also previously reduced manpower for the same purpose. However, Corus Strip Products is a business with deeply committed people and a relatively low staff turnover. Total payr oll costs are low compared with its other costs such as energy and raw materials. Labor costs at CSP UK account for around only 13% of total costs. This is considerably less than, for example, an assembly line process where they might be around 40-50% of total costs.It therefore made better sense to enable employees to work more efficiently rather than cut the number of staff. Barriers to change Change may challenge peoples’ abilities, experience, customs and practice. It may even be seen as a threat. This can create resistance or barriers to change. For example, if job roles are changed, employees and managers may feel that they lose status or power. If jobs are cut, remaining employees may feel insecure. This can cause low morale and lead to poor productivity.Although Corus Strip Products as a company supported the principles of change and innovation, not all previous programs had delivered the required results. GLOSSARY Corus is an established business in a traditional ind ustry. This meant that it had set patterns of doing things in some areas of the business. This attitude of ‘this is the way we do things around here’ made it more difficult to make necessary changes. Some Corus employees had a fear of the unknown and saw new initiatives as a possible threat to their existing teams and positions.Job reductions had been a major theme in the steel industry since the 1970s and some of Corus’ previous change initiatives had led to job cuts. Other people did not see a threat to their job because the business had previously survived difficult times. This complacency made change difficult for Corus. Another issue facing Corus was its ageing workforce. There is a considerable degree of expertise in the company and long-term high rewards kept people within the industry. Older employees with high technical skills stayed because these skills were not easily transferable.Fewer young people were attracted to the industry because of reduced job opportunities and reductions in apprenticeship schemes across the UK. The company also had a history of rewarding ‘long service’ rather than ‘distinguished service’. This means that employees who had been with the company a long time (but who had lower productivity) could be gaining greater rewards than newer employees who were producing more. Corus felt that this was an area that needed major change so that those employees with higher output were suitably rewarded. Overcoming barriers We cannot solve our problems by spending; we cannot solve our problems by cutting back. The only way to meet our challenges is to change how we go about things†¦Ã¢â‚¬â„¢ (quote from the Managing Director of CSP UK). One of the key techniques Corus has used to overcome resistance to change has been to work closely with employees and get them involved as much as possible in the program. From the start it was important for the company to share with employees what might hap pen to the business if it didn’t change. Corus put emphasis on getting everyone to take ownership of the new values by physically signing up to the program.This helped them ‘buy-into’ the new ways of working. Workers are now more involved in decision making and their contributions and experience are recognized. Through a range of direct and indirect communications, for example, weekly newsletters and workshops, Corus ensures that all employees understand what behaviors it expects of them. As part of implementation, Corus needed to highlight how people were behaving (the ‘As Is’). It created a program with ‘shock tactics’ to show managers and employees the condition of the plant, to identify weaknesses and encourage employees to make changes.For example, 150 senior managers were invited to the Millennium Stadium in Cardiff. This impressive venue raised expectations. However, they were served cold tea and given a presentation on a ripped p rojector screen. The fact that attendees did not comment on this demonstrated that people did not see they had a ‘right to challenge’. It also highlighted that employees had become accustomed to working with limited resources and were willing to accept low standards. This would be an important aspect to work on during the culture change.Managers were also shown videos of poor working conditions and interviews with local schoolchildren in which they said they would not work at the plant because of their perception of a poor outlook and a poor working environment. Around 150 workshops were held to spread the messages. Fortnightly newspapers clarified these values and repeated the key messages through articles on various activities, such as employees taking part in the redesigning of a control room to improve layout and safety. Billboards, intranet, video programs and most of all, direct one-to-one conversations all reinforced the messages.The Journey also raised important questions about how the company managed key issues, such as alcohol or drug misuse. The new values Due to the high standards of safety associated with Corus processes, all working sites are alcohol-free. Understandably, before the change program, anyone offending in this way was likely to face disciplinary action and this is still the case in most working environments. The new CSP UK values focus on helping employees who are willing to accept assistance to improve their performance, rather than taking disciplinary action against them for poor behaviour.This approach, with support and guidance from the company and counseling services, has resulted in over 50 employees that previously would have lost their jobs being retained in work. Measuring the outcomes of change The Journey change program at Corus Strip Products contributes to sustainability for the business. By facing up to its internal weaknesses, Corus Strip Products has improved efficiency, increased output, lowered costs an d reduced waste in an increasingly competitive steel market.This has enabled the business not just to survive but also to grow – even during the economic recession of 2008 and 2009. Thanks to the Journey program, CSP UK expects to reduce costs for the 2009/10 financial year by around ?250 million. To make sure that actions delivered results, Corus established clear targets and standards. Milestones (intermediate steps) were set so everyone would know how far CSP UK had gone to achieving the targets. This made it easier to review and measure progress and achievements or to set new deadlines.There have been a huge number of ‘quick wins’ which add up to a great gain overall. Key performance indicators have shown significant progress and include: †¢ production capacity has increased by 4. 5% to a run rate of 5 million tones †¢ the plant is on track to achieve a 20% reduction in the cost of producing steel †¢ 5,000 employees have signed up to the values and beliefs of the business †¢ a reduction in absenteeism †¢ measurable improvements in levels of quality and service for customers †¢ tighter targets for Health and Safety – new safety teams contribute towards accident-free production carbon dioxide emissions have reduced by 10%. CSP UK now exceeds government standards †¢ measurable improvements in the company’s impact on the local community. Individuals, teams and departments all support the improvement culture and are more engaged and committed to achieving company values and targets. This culture shift is of critical value as it will enable further improvement. For example, Corus has implemented top-level security with controlled access for the 5000+ vehicles which enter the Corus site each day.This provides a new enhanced ‘entry experience’ for employees, contractors and suppliers and demonstrates that Corus Strip Products is now seen as an organization that is proud of itself. Co nclusion All organisations need to manage change. If they fail to do so they may be left behind by the competition. Change management at Corus Strip Products UK involved bringing the issues out into the open, confronting barriers to change, winning the commitment and support of all employees and delivering an effective plan for change.The Journey has helped CSP UK to ‘weather the storm’. The company is now exploiting the benefits the program has given. The results of the change management program show that Corus Strip Products is a company that is sustainable and can continue to make profits in spite of the recession. Demonstrating ongoing improvement has the additional benefit of winning government grants to support the important economic sector of steel production. Overcoming Barriers to Change The research aims to identify barriers that exist in education on the way to changing students’ learning environments in a positive way. The literature review has revealed that current practices often demonstrate new opportunities willingly embraced by teachers.However, in many cases, teachers are not as susceptible to practices that threaten to have negative effect on their customary routines, in particular exemplified by collaborative teaching. Using teacher survey, the study will determine to what degree such reluctance can stand in the way of the teaching innovation.IntroductionTeaching collaboration is an idea that has gained prominence in contemporary educational establishments. Although at first a really unusual practice, collaboration in teaching has been shown to deliver great benefits.For educators themselves, â€Å"collegiality breaks the isolation of the classroom and brings career rewards and daily satisfactions† (Inger, 1993). It also helps beginners and e xperienced professional learn from each other for improved results and relieves young teachers of the trial-and-error process they are usually immersed in. bringing teachers closer together in a coherent effort, collaborative teaching helps foster cooperation and friendliness between teachers. Collaboration can also go beyond the level of a single school, helping extend new methods to other areas.At the same time, collaboration is not always compatible with school culture and practices and character of an individual teacher; hence come barriers to collaborative teaching. A teacher can be resistant to collaboration in general, being averse to any form of joint efforts in the same classroom. On the other hand, the teacher’s attitude can embrace collaboration between vocational and academic teachers or those coming from other schools. Therefore, the research problem is as follows:What obstacles do teachers most often face on the path of innovation in their school curriculum that involves collaborative teaching?The study will be focused on teacher perceptions and aim to find material so as to substantiate improvements in collaborative practices.Literature ReviewCollaboration can occur at any stage of the educational process. Teaching can engage in joint preparation of materials for the classroom sessions or engage in team teaching, or â€Å"organizational and instructional arrangement in which two or more teachers work in the same classroom† (Price et al, 2000-2001). Thus, in special education teachers can use a variety of models including the resource room, itinerant, and consultation models (Price et al, 2000-2001).In the process of realizing collaboration models, teachers face barriers that have been categorized by Welch and Sheridan (1995) into four main groups: conceptual barriers, pragmatic barriers, attitudinal barriers, and professional barriers. Conceptual barriers are caused by differences in the definition of roles by different educators, their difference in the processing of material, approaches etc.When teachers face challenges in working out the exact schedule or joining resources for joint effort, this is described as a pragmatic barrier. Attitudinal barriers are the result of fear to try a new approach. Professional barriers arise when teachers cannot cooperate on effective methods of problem solving, lacking adequate skills of working together as a team.Teachers can benefit from the administration’s effort to introduce additional measures so as to reduce the possibility of conflict among teachers.For this purpose, it is necessary to introduce concrete rules and procedures that will define the boundaries between their roles and help them establish working relationships. In case of team teaching, â€Å"the problem is getting a balance between enough specificity in prescribing roles so that a bureaucratic rule book is not created† (Price et al, 2000-2001). Most researchers believe that conflict is un avoidable, and therefore strategies for coping with it should be worked out by the administration in advance.A lot depends on the organizational culture as school culture can either stimulate or defy the efforts of teachers to work together. Peterson (2002) identifies two types of culture: cooperative and toxic. Within toxic cultures, individuals are striving to work together for common goals. As a result, teachers can reach effective collaboration more easily than in other organizations. In toxic cultures, on the contrary, individual effort is frustrated because of the lack of common framework.In addition, organizational resources can also be a barrier to innovation that should be represented in teaching communities. Many schools lack adequate programs that can accommodate the participation of two or more teachers. There are even fewer resources available for attracting outside professionals that can participate in collaborative projects. This can serve as a motivator for teachers to desire the continuation of the routines currently present in education.Cooperation between academic and vocational teachers can be prevented by the organizational design of the academic environment in which â€Å"the social and organizational isolation of most vocational teachers is exacerbated by the physical separation and programmatic fragmentation in secondary schools† (Inger, 1993).The difference in their social status further contributes to the rising walls between these two groups of professionals. Since academic teachers generally have a higher status, they tend to marginalize their vocational colleagues, a situation that discourages cooperation.
