British Postwar Cinema 1960-1990 - Essay Example of the time envisaging these movies to be heralding a ‘renaissance in British cinema.’ [Aldgate, 2006] While British New Wave and the social realism of the post-war years effectively disappeared from the big screen by the mid 60s, realism of the New Wave continues to influence filmmakers as Mark Herman, Ken Loach and Mike Leigh, evident in their respective movies Brassed Off (1996) All Or Nothing (2002), Sweet Sixteen (2002). The New Wave was essentially the British response to French contemporary equivalent—the auteur cinema of Nouvelle Vogue by Truffaut, Godard and others, which focussed on innovative narrative and cinematic techniques, vitally making cinema a personal expression of the director. Even as the British New Wave drew significantly from auteurism of the Nouvelle Vogue, adapting literary and theatrical source material and focusing on realism, the ‘tell-it-like-it-is New Wave movies distinctly differed from its French counterpart in form and style. Perceivably influenced by documentary-style realism, New Wave artistically combined the vision of the novelists or the playwright, and cinematic creativity of the director. The paper attempts to analyse the creative aspirations and the artistic influences of the New Wave filmmakers with a view to understanding and categorising the essential genre of British New Wave, as a cinema of the auteur or as a cinema of the writer. Yet, central to the analysis is the idea that while essentially following the historic tradition of British Cinema of adapting successful dramas and novels and persevering the spirit of documentary-style realism of Free Cinema, the British New Wave adapted and altered the auteur theory of contemporary French cinema, combining the art and craft of the writer and director in distinctly remarkable ways. Crucial to the analysis may be an understanding of the historical development of the movement, and the motives and motivations of the New Wave filmmakers. The mid-1950s, a period of

Study on Brady Udall Essay Example | Topics and Well Written Essays - 1000 words

Study on Brady Udall - Essay Example The thesis statement of this paper is that in his book, Letting Loose the Hounds, Brady Udall provides his characters an opportunity at hope to support his claim that dealing with the themes of sadness, despair and darkness alone cannot make a book candid and real.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Jerry, the protagonist and the narrator of Midnight Raid, is a representative of those people who are dealing with the pain of lost love. "Midnight Raid", perhaps the widely acclaimed story of Udall which is also the first story in this book, reflects the themes of darkness and confusion in the beginning itself. Through the simple, crispy and witty narration by Jerry we come to know that Jerry, drunk, is at the backyard of his â€Å"ex-wife Amy and her new husband Howard† (Udall) at Scottsdale, Arizona, to see his â€Å"seven-year-old son, Tate† and to gift him a goat â€Å"without Amy or Howard finding out about it† (Udall). Here, Jerry, who lost his son in the legal battle to his ex-wife Amy, has come to meet him. Though Jerry is aware about the negative consequences of his action, he deliberately puts in an effort to see his son and communicate his love. Though he had a troubled relation with Amy he was a loving father to Tate.  Ã‚   Hence, Jerry though convinces himself that his relation with Amy ended due to the indiscretions and betrayals  Ã‚   from both sides and that Howard is Amy’s new Husband, he fails to convince the father in him. Jerry, at the moment, is fragmented and is heartbroken.     Ã‚  Ã‚  Ã‚  Ã‚   Midnight Raid is essentially a tragic story which has been tamed well to make it candid and real.   Jerry as well as other characters portrayed in Udall’s stories is found to be constantly dealing with the confusion whether to accept or to fight their sad circumstances. They are stuck in the battle of wills and are constantly being torn apart between ‘letting go’ and ‘wanting to let go’. In t he case of Jerry, we can see that he is confused and worried about his wife who "left [him] to marry this liver-spotted senior citizen with dentures and an artificial leg". He consoles himself at the thought that Howard is rich enough to provide financial security to Amy. His mind is "completely scraped out from the inside" when he finally left his loved ones with Howard.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Udall by making Jerry the protagonist of Midnight Raid is purposefully interweaving humor in to the dark rather unpleasant story. Jerry, the narrator and the protagonist of Midnight Raid, was introduced by Udall as a six-foot-three Apache Indian carrying a goat into his ex-wife's back yard in the middle of the night. Udall bestows Jerry with comic sense that does not get stained even at the face of his desperation, which is evident from many of the passages of the story.   An instance for this is when Jerry, while narrating the â€Å"end of relationship story" states that his â€Å"divor ce was an honest, smash-mouth affair† (Udall).   Udall, in an interview by Robert Birnbaum, regarding the presence of comic in his stories, commented that "a book can't just be all darkness, all dark notes...I owe my characters some opportunity at hope or redemption. It's not going to be the redemption that the reader expects...I respect my characters...I can't just hurt them and kill them just for my purposes...It would be too much for me to do

Resistors in series and parallel Essay Example for Free

Resistors in series and parallel Essay Resistors are used in various real life applications to perform tasks that involve: limiting the current that goes through a section of a circuit, introducing a voltage drop in a circuit, generating heat and the protection of components of a circuit. It is important to calculate the resistance of resistors so that the electrical circuits produced using them will perform in the manner that their manufacturer wanted them to. If the wrong resistance/resistor is used then delicate components that need only a relatively small amount of current may be destroyed. All resistors have a level of tolerance. This is to allow for imperfections in the manufactured object. It was determined through experimentation that all of the resistors that were used in this experiment were within their tolerance range with the exception of R4 (See Table 1). This resistor had a nominal value of 1600 ohms and a tolerance of +/-5%. This means that this resistor should have had a value within the range of 1520-1680 ohms, however  the actual resistance was found to be 1798 ohms. It is possible that this may have been due to a manufacturing fault or a labelling error. The total predicted resistance was determined by using the series and parallel resistor laws and the resistance values of the various components of the circuit. The tolerance range for the circuit was predicted to be between 1847.3-2319.2 ohms. Through experimentation the actual total resistance for the circuit was 2216.62 ohms, this value was within the predicted range. The actual resistance value of component 1 was 263.26 ohms; this was within the predicted range (271.36-245.51 ohms). The actual resistance value of component 2 was 1764.26 ohms; this was within the predicted range (1664.24-1846.36 ohms). The actual resistance value of component 3 was 2216.62 ohms; this was within the predicted range (2319.20 and 1847.3 ohms). The actual resistance of the resistors was found by using a multimeter. Some systematic error may have occurred in this experiment if the multimeter was not calibrated correctly during testing. Temperature fluctuations may have caused inconsistencies in this experiment. The reason why resistance occurs is that a metal consists of lattice of atoms that each has a shell of electrons. The metal is a conductor because the electrons are free to dissociate from their parent atoms and travel through the lattice. When a voltage is applied the electrons drift from one side of the metal to the other. In real material imperfections scatter the electrons resulting in resistance. Temperature is able to affect resistance because temperature causes the atoms to vibrate more strongly creating even more collisions and further increasing the resistance. Conclusion: The aim of the experiment was to compare the predicted and actual resistance in the circuit of resistor combinations in series and parallel. The results of this experiment found that the series and parallel resistor laws were reasonably good indicators of the real world values of resistance for circuits that contained resistors in series and parallel. One example of this was that the total resistance of the circuit made was found to be 2216.62 ohms which was within the predicted range (this predicted range was calculated by using the upper and lower tolerance values for the resistors used in the circuit. From the data obtained it can therefore be seen that all three resistor laws stated in the Background section of this report are quite useful in calculating theoretical values for the resistance of circuits in series and parallel that are close to the real world values.

Analysing Different Ethical Theories Philosophy Essay

Analysing Different Ethical Theories Philosophy Essay Ethics may be viewed as the study of human conduct with an emphasis on determination of right and wrong (Fraedrich and Ferrell, 1992). Together with this, it is the assumption that management must adhere to a narrow version of positivism that excludes any reference to intention (Ghoshal, 2005). According to (Mallor et al., 2010), for centuries, religious and secular scholars have explored the meaning of human existence and attempted to define a good life. Ethical theories and principles are the foundations of ethical analysis because they are the viewpoints from which guidance can be obtained along the pathway to a decision. The four ethical theories according to the text are rights theory, justice theory, utilitarianism, and profit maximization. The rights theory covers a range of ethical philosophies that holds that certain human rights are important and must be respected by other society and her rights. Rights are also considered to be ethically correct and legitimate given that a large or ruling population endorses them. Few rights theorists are stringent deontologists, and one of the few is the 18th century philosopher by name Immanuel Kant and his theory is known as the Kantianism. Kant viewed humans as moral actors that are free to make choices and he also believed that humans are able to judge the morality of any action by applying his famous categorical imperative. One of his formulations of the categorical imperative is Act only on that maxim whereby at the same time you can will that it shall become a universal law. The meaning of it is that we judge an action by applying it universally. The most important strength of rights theory is that it protects fundamental rights, unless some greater right takes precedence. A major criticism of the rights theory deal with the near absolute yet relative value of the rights protected, making it difficult to articulate and administer a comprehensive rights theory. The Justice theory which came into limelight by John Rawls in 1971 when he published his book entitled: A theory of Justice, the philosophical underpinning for the bureaucratic welfare state. He reasoned that it was right for governments to redistribute wealth in order to assist the poor and the destitute. Furthermore, Rawls expressed this philosophy in his Greatest Equal Liberty Principle: each person has an equal right to basic rights and liberties. He further limited the principle with the Difference Principle: social inequalities are acceptable only if they cannot be eliminated without making the worst-off class even worse off. Rawlss justice theory has application in the business context which requires decision makers to be guided by fairness and impartiality. The strength of Rawlss justice theory lies in its basic premise, the protection of those who are least advantaged in society. The ethical dilemma for managers is to determine the fair rules and procedures for distributing outcomes to stakeholders. Managers must not give people they like bigger raises than they give to people they do not like, for example, or bend the rules to help their favorites. On the other hand, if employees want managers to act fairly toward them, then employees need to act fairly toward their companies and work hard and be loyal. Similarly, customers need to act fairly toward a company if they expect it to be fair to them-something people who illegally copy digital media should consider. The criticism that justice theory with the rights theory is that it treats equality as an absolute, without examining the costs of producing equality, including reduced incentives for innovation, entrepreneurship and production. Utilitarianism entails a decision maker to maximize utility for society as a whole. Maximizing utility means achieving the highest level of satisfactions over dissatisfactions which means that a person must consider the benefits and costs of her actions to everyone in society. A utilitarian will take action only if the benefits of the action to society outweigh the societal costs of the action. There are two types of utilitarianism, act utilitarianism and rule utilitarianism. Act utilitarianism judges each act separately, assessing a single acts benefit and its cost to societys members. Rule utilitarianism judges actions by a rule that over the long run maximizes benefits over cost. The strength of utilitarianism as a guide for ethical conduct is that it is easy to articulate the standard of conduct; which coincides with values of most modern countries like the USA who is capitalist in nature by focusing on total social satisfactions, benefits, wealth and welfare. In general under ca pitalism, the interests of shareholders are put above those of employees, so production will move abroad. This is generally regarded as being an ethical choice because in the long run, the alternative, domestic production might cause the business to collapse and go bankrupt. If this happens, all of the companys stakeholders will suffer-not just its employees. According to the utilitarian view, the decision that produces the greatest good for the greatest number of people is best. In this case, that means outsourcing the jobs. The criticism of utilitarianism is that it is difficult to measure ones own pleasures, pains, satisfaction and dissatisfaction, let alone those of all of societys members. Profit maximization as an ethical theory requires a decision maker to maximize a businesss long-run profits within the limits of the law. This has been based on the laissez faire theory of capitalism first expressed by Adam Smith in the 18th century and more recently promoted by economists such as Milton Friedman and Thomas Sowell. Profit maximization is closely related to utilitarianism, but it varies essentially in how ethical decisions are made. Profit maximization optimizes total social utility by narrowing the actors focus, requiring the decision maker to make a decision that merely maximizes profits for himself or his organization. The strengths of profit maximization results in ethical conduct because it requires societys members to act within the constraints of the law and a profit maximizer, therefore, acts ethically by complying with societys mores as expressed in its laws. The criticism of profit maximizer is that if profit maximization results in an efficient allocation o f societys resources and maximization of total social welfare, it does not concern itself with how wealth is allocated within Society. An ethical theory that was not found in the text is that of rationalism, which this ethical theory focuses mainly on norms. The moral rationalism is that in which the decisive factor of the truth is not sensory but intellectual and deductive, and it has its major proponent in Emmanuel Kant (Llano, 2002). Mr. Kant attempted to change our everyday, clear, rational knowledge of morality into philosophical knowledge. He went after a technique of using practical reason to reach conclusions which are able to be useful to the world of experience. Kant is also known for his theory that there is a single moral obligation which he called the Categorical Imperative, and derived from the perception of duty. He further stated that these moral norms must be obeyed in all situations and circumstances if our behavior is to observe the moral law. In a way to improve corporate governance and corporate social responsibilities, according to Mallor et al., 2010, one can modify the corporate governance model to educate, motivate, and supervise executives and thereby improve corporate social responsibility. Corporate governance is the structure used to direct and manage business and affairs of the company towards enhancing prosperity and corporate accountability. Corporate critics however did propose a wide rang of cures, all of which have been implemented to some degree and with varying degrees of success. Ethical codes: Ethic codes in a way have been adopted by many large corporations and several industries to guide executives and other employees. The Sarbanes-Oxley Act required that a public company discloses whether it has adopted a code of ethics for senior financial officers, and to disclose any changes in the code or waiver of the codes application. The codes can be viewed in two ways; one sees the codes as genuine efforts to foster ethical behavior within a firm or an industry while others view regards them as thinly disguised attempts to make the firm function better, to mislead the public into believing the firm behaves ethically, to prevent the passage of legislation that would impose stricter constraints on business, or to limit competition under the veil of ethical standards. Better ethical codes make clear that the corporation expects employees not to violate the law in a mistaken belief that loyalty to the corporation requires it. These kinds of codes work best, however, when a corporation also gives its employees an outlet for dealing with a superiors request to do an unethical act. Ethical instruction: Some corporate organizations require their employees to enroll in classes that teach ethical decision-making. The idea is that a manager trained in ethical conduct will recognize unethical actions before they are taken and deter herself and the corporation from the unethical acts. Majority of corporations in this present day express their dedication to ethical decision-making by an ethics officer who is not only responsible for ethical instruction, but also in charge of ethical supervision. The ethics officer tends to be a mentor or sounding board for all employees who face ethical issues. Greater Shareholder Role in Corporations: As shareholders are the vital stakeholders in a corporation in a capitalist economy, several corporate critics argue that businesses should be more attuned to shareholders ethical values and that shareholder control of the board of directors and executives should be increased. Evidence suggests that sources of ethical dilemmas will continue to increase. To understand this assessment, it will be useful to look at four categories of conditions influencing ethical behavior: global, social, organizational and individual. Global: A variety of global conditions affect our lives and our society; many are well-known to all of us. They include the increasing influence of cultural values substantially different from those of our Anglo-Saxon heritage; impacts of a complex global economy on local economic structures; and our rapidly increasing technological capacity to communicate and interact with the global community. Within the past few years we have watched the beginning of the development of a new world order that will be substantially different from our sense of world order developed over the last half century. Among the implications resulting from this picture, two are especially important: (1) we as a people no longer have a secure sense of our role in the world or our control over it; and (2) it has become increasingly acceptable, and even logical, to admit that we simply dont know what the appropriate response is. This era of rapid change has an indirect but important influence on our sense of ethi cal appropriateness. Social: A more direct source of ethical conflicts is social change. Change has been so rapid that some have argued that we have lost our sense of values or that we must seek better mechanisms to resolve value conflicts. This line of reasoning is incorrect for several reasons. First, value conflicts (and, therefore, ethical dilemmas) reflect our social and cultural fabric. Second, stakeholders have a relatively easy time gaining access to our policy making system; therefore, value conflicts are very visible and, frequently, cause our problem-solving process to forge slow, painful compromises. These processes continue to represent one of the great comparative advantages of our society and should not be changed without sober reflection. Organizational: Thirdly, we are witnessing rapid change in the nature and role of the public organization and concepts about administrative behavior. Organizational values are vital influence on the majority of us; thus far our organizational lives are becoming increasingly participatory, open, communicative and interactive. While I believe that the decline of organization hierarchy is among the more positive aspects of our society, it also signals a decline in another source of behavioral guidelines. Individual judgment, group dynamics and social interactions are replacing traditional rules of behavior dictated by the organization. We are also facing increasing conflicts between the bureaucratic ethos and the democratic ethos (Hejka-Ekins, 1998). The bureaucratic ethos includes such traditional organizational standards as efficiency, competence, loyalty and accountability. Individual: lastly, ethical anxieties are caused by changes at the individual level. In particular, individualism and materialism are at the present celebrated within major social institutions and have become a dominate ethos of the baby bust generation. Self-indulgence, greed, self-interest, and privatism are accepted components of the ethos of this generation (Frederickson, 1982). In order to improve the ethical climate of an organization, management must effectively communicate proper ethical behavior throughout the organization. Wimbush and Shephard (1984: 637-647) reported that businesses annually spend an estimated $40 billion on the ethical behavior problems. Thus, pointing to the fact that ethical dimension of employees behavior has a clear impact on the profitability of the company. It is generally accepted that customer satisfaction is one of the most important factors in successful business strategy. Although a company must continue to develop, alter and adapt products to keep pace with customers changing desires and preferences. It must also seek to develop long-term relationships with customers and its stakeholders. By focusing on customer satisfaction, a company continually deepens the customers dependence on the company, and as the customers confidence grows, the firm gains a better understanding of how to serve the customer so the relationship ma y endure. Successful businesses provide an opportunity for customer feedback, which can engage the customer in a cooperative problem solving. As is often pointed out, a happy customer will come back, but a disgruntled customer will tell others about his or her dissatisfaction with a company and discourage friends from dealing with it. When an organization has a strong ethical environment, it usually focuses on the core value of placing customers interest first. An ethical culture that focuses on customers incorporates the interests of all employees, suppliers, and other interested parties in decisions and actions. Employees working in an ethical environment support and contribute to the process of understanding customers demands and concerns. Ethical conduct towards customers builds a strong competitive position that has been shown to affect business performance and product innovation positively.

Hamlet Essay -- essays research papers

During Shakespeare’s play Hamlet, the main character Hamlet has to deal with the responsibility of revenging his father’s murder. He learns of his tragic death when the ghost of King Hamlet comes to him and tells him the truth of his murder: he was killed by his brother Claudius, for his crown and his wife. Hamlet decides that the best plan of action is to fake madness to attain his father’s vengeance by murdering Claudius. As the play develops, Hamlets act of being a madman becomes more and more believable, and his friends and family react as you’d expect someone who is discovering that their loved one is slowly turning insane would. As we read the play and begin to understand Hamlet’s mentality, his inner thoughts, and the reasons for his actions, it becomes clear to the reader that Hamlet is, in fact, totally and healthily sane. It becomes evident that he is simply simulating insanity so that it is easier to fulfill his duties to his father, and that Claudius’s murder doesn’t rest so guiltily on his conscience. Hamlet only feigns madness because it allows him to do and say things that he otherwise could not say without severe repercussions and suspicion being held against him. It also prevents people from blaming him for his ridiculous antics, and from taking him seriously. We first see Hamlet’s initial plan of faking insanity falling into place when he is talking to Horatio and Marcellus, telling them not to comment to anyone about his â€Å"antic disposition (Shakespeare, 75).† Hamlet’s supposed madness allows him to talk to his friends, family, and especially to Ophelia in a manner that is totally unsuitable for a human being to act, especially a prince. He is completely disrespectful and insulting in his remarks, and although his antic disposition backfires while he is talking to his mother, it allows him to severely reprimand her actions and criticize her for her disloyalty to her deceased husband because Gertrude thinks he is insane. She therefore is very passive in her response to Hamlet, being very dismissive of his actions and harsh words because of his supposed insanity. Throughout the play, Hamlet also makes some very sexually inappropriate remarks to Ophelia such as â€Å"That’s a fair thought to lie between a maids` legs (Shakespeare, 157).† He can inappropriately vent his anger toward Ophelia for her abandonment in any way he pleases, being emotion... ...the play sane, normal, healthy, loving, but with the discovery of his father’s murder and his mother’s remarriage, he dies selfish, distraught, and cold-hearted. His feigned madness is maintained throughout the entire play because it allows him to follow through with his plans, which makes Hamlet not only completely sane, but truly genius. Maybe Hamlet thought too much, but he thought (and acted) as only a sane man could. He commits no actions whatsoever without much thought and reason, and he is far too organized, particular, and articulate to be proclaimed insane. His one downfall is also responsible of his many successes: his intelligence. Hamlet thinks far too much and has too much of a conscience to behave as a madman would, and going on a murdering rampage to kill Claudius. His hesitation in doing so is the main key that allows the reader to realize that Hamlet’s insanity is a complete farce, used to help Hamlet to maximize his father’s revenge a gainst Claudius in the most efficient and effective way possible, leaving few repercussions for Hamlet. Hamlet’s portrayal of a mad man is also very complicated because it not only gets his point made, but in a believably insane way.

Martin Luther Essay -- essays research papers fc

Martin Luther lived from 1483-1546. Luther was born on November 10, 1483 in Eisleben in the province of Saxony. His protestant view of Christianity started what was called the Protestant Reformation in Germany. Luther's intentions were to reform the medieval Roman Catholic Church. But firm resistance from the church towards Luther's challenge made way to a permanent division in the structure of Western Christianity.Luther lived in Mansfield and was the son of a miner. He later went on to study at Eisenbach and Magdeburg. After studying at these institutions he moved on to study at the University of Erfurt. Luther started out studying law, but then went on to enter the religious life. He went into the religious life due to the fact that he felt that he would never earn his eternal salvation. He didn't feel that all of the prayer, studying and sacraments were enough. Therefore, Luther felt that he would never be able to satisfy such a judging God. Not being able to satisfy this God meant eternal damnation. After entering the religious life he later became an Augustinian monk and entered the Augustinian monastery at Erfurt in July of 1505. While in this monastery Luther became a well known theologian and Biblical scholar. In 1512 Luther earned his doctorate in theology and became a professor of Biblical literature at Wittenberg University.Luther took his religious vocation very serious. This led him into a severe crisis in dealing with his religion. He wondered, "is it possible to reconcile the demands of God's law with human inability to live up to the law." Luther then turned to the New Testament book of Romans for answers. He had found, "God had, in the obedience of Jesus Christ, reconciled humanity to himself." "What was required of mankind, therefore, was not strict adherence to law or the fulfillment of religious obligations, but a response of faith that accepted what God had done." In other words he realized that religion is based on love and not fear. Basically, he realized that everyone is burdened by sin because it happens as a result of our weaknesses. He concluded that man could never earn his salvation by leading a blameless life or by performing holy acts. Instead, man's salvation was a divine gift from God resulting from faith in Jesus, especially the saving power of his death and resurrection. This was known ... ...accuracy and true meaning of the Word. He felt that the Roman Catholic Church preferred the Papal authority of the Church above God's Word. How did Luther define faith? Luther defines faith as the absence of all good works. What were Luther's objections to the Pope and other church officials? He felt that the Pope and other officials of the Catholic Church had no knowledge or comprehension of the Bible or had ever even read it. They were wicked people who were preoccupied with wealth and power, but who never considered accomplishing God's will. What political and social implications came as a result of Luther's teachings? His teachings caused a revolt among the German peasants. They also caused separation within the Catholic Church. How did Protestantism encourage people to view religion on an individual basis? Protestantism encouraged people individually to decide what they needed to do to be saved. This caused people to stray away from traditional beliefs. Bibliography.(Martin Luther).

Alligator Cracking

ALLIGATOR CRACKING AN INTRODUCTION :- Crocodile cracking, also called fatigue cracking or alligator cracking, is a common type of distress in asphalt pavement. Crocodile cracking is characterized by interconnecting or interlaced cracking in the asphalt layer resembling the hide of a crocodile. Cell sizes can vary in size up to 300 millimetres (12  in) across, but are typically less than 150 millimetres (5. 9  in) across. Crocodile cracking is generally a loading failure, but numerous factors can contribute to it. It is often a sign of sub-base failure, poor drainage, or repeated over-loadings.It is important to prevent crocodile cracking, and repair as soon as possible, as advanced cases can be very costly to repair and can lead to formation of potholes or premature pavement failure. CAUSES OF ALLIGATOR CRACKING :- * Crocodile cracking is an asphalt pavement distress most often instigated by failure of the surface due to traffic loading. * Crocodile cracking can be greatly influe nced by environmental and other effects while traffic loading remains the direct cause. Frequently, overloading happens because the base or subbase inadequately support the surface layer and subsequently cannot handle loads that it would normally endure. Poor drainage in the road bed is a frequent cause of this degradation of the base or subgrade. A heavy spring thaw, similarly to poor drainage, can weaken the base course, leading to crocodile cracking. * Stripping or raveling is another possible cause of crocodile cracking. Stripping occurs when poor adhesion between asphalt and aggregate allows the aggregate at the surface to dislodge. If left uncorrected, this reduces the thickness of the pavement, reducing the affected portion's ability to carry its designed loading.This can cause crocodile cracking to develop rapidly, as overloading will happen with loads of less magnitude or frequency. CAUSES OF ALLIGATOR CRACKING :- Failure of surface due to loading Stripping of bitumen due t o poor adhesion of bitumen ; asphalt Environmental conditions :- (a) Due to excessive rain b) hot weather (c) frost action CHARACTERISTICS or IDENTIFICATION :- * Crocodile cracking manifests itself initially as longitudinal cracking (cracks along the direction of the flow of traffic) in the top layer of the asphalt. * These cracks are initially thin and sparsely distributed. If further deterioration is allowed, these longitudinal cracks are connected by transverse cracks to form sharp sided, prismatic pieces. * This interlaced cracking pattern resembles the scales on the back of a crocodile or alligator, hence the name, alligator cracking. * More severe cases involve pumping of fines, spalling, and loose pieces of pavement. * The most severe cases of crocodile cracking often occur with other pavement distresses, but are exemplified by: potholes, large cracks(3/8†³ or larger), and severely spalled edges. MEASUREMENT & QUANTIFICATION :-There are many different ways to measure cro codile cracking, but in general a pavement distress manual or index will be used. For example, the Pavement Condition Index is widely used to quantify the overall level of distress and condition of a section of road. Measurement of crocodile cracking specifically(and pavement distress in general) is necessary to determine the overall condition of a road, and for determination of a time-line for rehabilitation and/or repair. There are many other rating systems, and many rating systems currently in use are based on the AASHO Road Test.There are two important criteria to take into effect when measuring crocodile cracking. The first is the extent of the cracking. This is the amount of road surface area which is affected by this pavement distress. The second criterion is the severity of the cracking. Severity, which has been discussed above, refers to how far the cracking has progressed, and is often directly a function of crack width. Severity may be rated numerically, or given a rating from â€Å"low† to â€Å"severe†. The rating may be entered into a pavement management system, which will suggest a priority and method for the repair.Systems have been developed that detect crocodile and other types of pavement distress automatically. They measure the severity and frequency of alligator cracking on the road-path. One such machine is the road surface profilometer, which is mounted on a vehicle and measures the profile of the road surface while it is moving down the roadway. PREVENTION & REPAIR :- Preventing crocodile cracking can be as simple as preventing the common causes. Reducing overloading on an asphalt pavement or improving drainage can prevent crocodile cracking in many cases.However, often the specific cause is fairly difficult to determine, and prevention becomes difficult correspondingly. A good strategy to prevent overloading, which is a main cause of crocodile cracking, is to increase the depth of the asphalt layer. According to certain r esearchers, pavements of a minimum strength or thickness can hypothetically handle infinitely many loads without showing structural defects, including crocodile (fatigue) cracking. These pavements are called perpetual pavements. When repairing pavement affected by crocodile cracking, the main cause of the distress should be determined.Any investigation should involve digging a pit or coring the pavement and subbase to determine the pavement's structural makeup as well as determining whether or not subsurface moisture is a contributing factor. The repair needed also differs based on the severity and extent of the cracking. In the early stages, sealing cracks with crack sealant limits further deterioration of the subgrade due to moisture penetration. Small areas may be repaired by removal of the affected area, and replacement with new base and asphalt surface.Once the damage has progressed, a structural asphalt overlay or complete reconstruction may be necessary. CONCLUSION When repai ring pavement affected by crocodile cracking, the main cause of the distress should be determined. However, often the specific cause is fairly difficult to determine, and prevention is therefore correspondingly difficult. Any investigation should involve digging a pit or coring the pavement and sub base to determine the pavement's structural makeup as well as determining whether the moisture is a contributing factor.Small areas may be repaired by removal of the affected area, and replacement with new base and asphalt surface. Once the damage has progressed or the affected area is large and extensive, a structural asphalt overlay or complete reconstruction is necessary to ensure structural integrity. If the government also takes necessary action by giving an yardstick of the maximum ESWL that can be allowed, then cracking can be prevented. However in practical it is not possible always. Our conciousness also plays a great role. If we can understand what can cause cracking and take ne cessary action, then it can be prevented.
