How to Name a Dinosaur

Most working paleontologists dont get the opportunity to name their own dinosaur. In fact, for the most part, paleontology is a somewhat anonymous and tedious occupation--the typical Ph.D. candidate spends most of her days laboriously removing encrusted dirt from newly discovered fossils. But the one chance a field worker really gets to shine is when he or she discovers--and gets to name--a brand-new dinosaur. (See The 10 Best Dinosaur Names, The 10 Worst Dinosaur Names, and the Greek Roots Used to Name Dinosaurs.) There are all sorts of ways to name dinosaurs. Some of the most famous genera are named after prominent anatomical features (e.g., Triceratops, Greek for three-horned face, or Spinosaurus, the spiny lizard), while others are named according to their presumed behavior (one of the most famous examples is Oviraptor, which means egg thief, even though the charges later turned out to be overblown). A bit less imaginatively, many dinosaurs are named after the regions where their fossils were discovered--witness the Canadian Edmontosaurus and the South American Argentinosaurus. Genus Names, Species Names, and the Rules of Paleontology In scientific publications, dinosaurs are usually referred to by their genus and species names. For example, Ceratosaurus comes in four different flavors: C. nasicornus, C. dentisulcatus, C. ingens, and C. roechlingi. Most ordinary people can get by with just saying Ceratosaurus, but paleontologists prefer to use both the genus and species names, especially when describing individual fossils. More often than you might think, a species of a particular dinosaur is promoted to its own genus--this has happened numerous times, for instance, with Iguanodon, some former species of which are now referred to as Mantellisaurus, Gideonmantellia, and Dollodon. According to the arcane rules of paleontology, a dinosaurs first official name is the one that sticks. For example, the paleontologist who discovered (and named) Apatosaurus later discovered (and named) what he thought was an entirely different dinosaur, Brontosaurus. When it was determined that Brontosaurus was the same dinosaur as Apatosaurus, official rights reverted back to the original name, leaving Brontosaurus as a deprecated genus. (This sort of thing doesnt only happen with dinosaurs; for example, the prehistoric horse, formerly known as Eohippus, now goes by the less user-friendly Hyracotherium.) Yes, Dinosaurs Can Be Named After People Surprisingly few dinosaurs are named after people, perhaps because paleontology tends to be a group effort and many practitioners dont like to call attention to themselves. Some legendary scientists, though, have been honored in dinosaur form: for example, Othnielia is named after Othniel C. Marsh (the same paleontologist who caused the whole Apatosaurus/Brontosaurus brouhaha), while Drinker wasnt a prehistoric alcoholic, but a dinosaur named after the 19th-century fossil hunter (and Marsh rival) Edward Drinker Cope. Other people-saurs include the amusingly named Piatnitzkysaurus and Becklespinax. Perhaps the most widely recognized people-saur of modern times is Leaellynasaura, which was discovered by a married pair of paleontologists in Australia in 1989. They decided to name this small, gentle ornithopod after their young daughter, the first time a child had ever been honored in dinosaur form--and they repeated the trick a few years later with Timimus, an ornithomimid dinosaur named after the husband of this famous duo. (In the past few years, there have been many more dinosaurs named after women, correcting a long-time historical imbalance.) The Silliest, and Most Impressive, Dinosaur Names Every working paleontologist, it seems, harbors the secret desire to come up with a dinosaur name so impressive, so profound, and so just-plain-cool that it results in reams of media coverage. Recent years have witnessed such unforgettable examples as Tyrannotitan, Raptorex and Gigantoraptor, even if the dinosaurs involved were less impressive than you might think (Raptorex, for example, was only about the size of a full-grown human, and Gigantoraptor wasnt even a true raptor, but a plus-sized relative of Oviraptor). Silly dinosaur names--if theyre within the bounds of good taste, of course--also have their place in the hallowed halls of paleontology. Probably the most famous example is Irritator, which received its name because the paleontologist restoring its fossil was feeling, well, particularly irritated that day. Recently, one paleontologist named a new horned, frilled dinosaur Mojoceratops (after the mojo in the expression Ive got my mojo working), and lets not forget the famous Dracorex hogwartsia, after the Harry Potter series, which was named by pre-teen visitors to the Childrens Museum of Indianapolis.

Women s Rights Of Female Athletes - 2133 Words

In 1972, Title IX has banned sexual unfairness not only in education programs, but also in the athletic programs. This federal law applies to all organizations that receive federal funds and must function in an equal manner. Gender equity has been a major problem in our society for quite some time, and now it has migrated to athletics. According to the Office of Civil Rights some keys issues which recipients have Title IX obligations are: â€Å"recruitment, admissions, financial assistance; athletics; sex-based harassment; treatment of pregnant and parenting students; discipline; single-sex education; and employment† (OCR, 2015). Fair treatment for female athletes has been a huge matter in athletics. The Office of Civil Rights issued guidelines offering equal opportunity rights to all athletes including the temporary disability of pregnant female athletes. Prior to OCR putting this policy to effect there were many reasons universities neglect pregnant female athletes. Accord ing to Pitt Law there are a few reasons: â€Å"first, too many individuals in society believe sport is â€Å"pervasively masculine organization that is constructed around men. Secondly, women’s ability to reproduce is used against them to exclude them from sports.

Female managers at Nagel Free Essays

One of the most important issues concerning the workforce at Nagel Partners is its gender demographic. The proportion of male to female employees is approximately even at the lower levels. However, the number of female role models available to these women employees is disproportionately low, amounting to only about 10% at the executive levels. We will write a custom essay sample on Female managers at Nagel or any similar topic only for you Order Now Nagel Partners’ executives have expressed concern about the profitability of training more female employees to fill managerial and executive positions, and this concern is justified. However, it would prove very beneficial to this firm to embark on such a training scheme, since many women do tend to give out their best performance under situations that are generally different from those that male leaders and managers are able create. One of the major divisions in leadership type is between task-oriented (production-oriented) and relationship-oriented (employee-oriented) leaders. While a task-oriented leader tends to focus on the accomplishment of production goals, relationship-oriented leaders are foremost concerned with the well-being of their subordinates (Lewitz Bem, 1983). However, once the task has been accomplished, the task-oriented leader is usually better able to focus on relationships. The opposite is true for relationship-oriented leaders, who are able to facilitate the optimal completion of tasks once it has been established that needs of subordinates (or of the group) have been met (1983). In a firm like Nagel Partners, which focuses on a predominantly task oriented job (accounting), task orientation is a necessity. However, considering that employees are human beings, a holistic look at management would warrant the inclusion of a more relationship-based orientation. The type of leader that a woman will prove to be (whether task- or relationship-oriented) may have an impact on her performance as a manager. Though this cannot be considered true in all instances, women have generally been perceived as being more relationship-oriented than men (â€Å"Masculine and Feminine,† 2005). This has also been seen by many as having the ability to affect productivity as a manager in a task-oriented firm. However, in a firm with such a large population of valuable women workers as Nagel Partners, it can be seen that women do have the capability to perform tasks well. Furthermore, it has been stated by several leadership researchers that leaders who are relationship oriented lead divisions that perform as well as those of leaders who are task-oriented (2005). One of the keys behind this is the fact that relationship-oriented leaders are capable of creating an atmosphere in which tasks can be performed at optimal levels (2005). Since women generally have a natural proclivity toward being relationship oriented (â€Å"Masculine and Feminine,† 2005), then the need for such a leader might be considered to be very large at Nagel Partners. Females workers trained to occupy leadership positions are likely to have a positive effect on the productivity of their female subordinates, as they have a natural inclination toward creating the atmosphere in which these persons can produce their best work. Training would, however, likely be necessary in an effort to increase these female managers’ tendency toward the more task-oriented goals of giving directions to and setting standards for employees. The ability for employees to identify with those in leadership positions is also an important component in a manager’s power or influence with employees. The large proportion of women on the payroll at Nagel Partners would allow for increased identification, were more women to be trained and placed in managerial and executive positions. Despite this fact, it has also been shown that many females have trouble subordinating men (Lewitz Bem, 1983). Some women may have an innate problem with this, while others might come across male employees who are reluctant to behave subordinately toward a female manager. Since as many men as women work at Nagel Partners, training is necessary to improve prospective female managers’ ability to relate well to both sexes. This is an especially good idea since it has been shown that training has the ability to transform less assertive women by increasing their assertiveness in given situations. Women were able to increase the efficacy of their performance in mixed-sex groups as a result of such intervention (1983). Therefore, training women to become managers in this firm would prove beneficial. One possible challenge to be faced by increasing the number of female managers is that in the workforce culture of the United States, masculinity as a leadership type seems to be generally given a higher value. First of all, this operates under the assumption that achievement and assertiveness are masculine traits. While this is not always the case, when training female leaders, considerations should be made regarding methods of enhancing (or, if need be, instilling) those attributes. The fact that these women will be leading other women makes any inherent femininity traits an invaluable leadership tool. However, the fact that these women would also be leading men makes it necessary that those who do not already possess masculinity traits be trained in that area. All these factors would make the training of female managers very beneficial to Nagel Partners.

Issue 7 Should Abstinence Be the Goal for Treating People with Alcohol Problems free essay sample

University of Phoenix Material Critical Issue Analysis (Tamara Hayes) Week 4†¦Ã¢â‚¬ ¦ Issue 7: Should Abstinence Be the Goal for Treating People with Alcohol Problems? After reading the selected critical issue, use the following questions to analyze the issue. 1. What are at least two facts presented by each side of the critical issue? YES FACT 1: Studies show that about half of people wanting to stop drinking are successful (Halgen, 2009). Fact 2: Abstinence is the goal for treatment on alcohol not just the twelve step program. NO FACT 1: Alcoholic experts state that most drunk driving offenders are not alcoholics. Yet they are presently the largest group of people in a court order program. FACT 2: A study in 1990 found that more three quarters of two hundred randomly selected treatment programs saw controlled drinking as an unaccepted goal† (Halgen, 2009, p. 184). 2. What are at least two opinions presented by each side of the critical issue? †¢ YES Opinion 1: Abstinence does not mean the recovery alcoholic will have a life of sadness due to feeling deprived. Opinion 2: Because of how hard abstinence is, it might take more than one attempt to stop (Halgen, 2009). NO Opinion 1: Not all people who abuse alcohol are alcoholics. Opinion 2: There can be abusers of alcohol, who are people drinking irresponsible and who are not alcoholics (Halgen, 2009).. 3. What are some of the strengths associated with the Pro side of the issue? What are some of the weaknesses? Strength: A strong argument for abstinence is that if one has trouble controlling their drinking then how would one modify it. Weakness: Yet AA will also say that if you are a moderate alcoholic then you should be able to modify your drinking. I just get this statement. I do not see people as little alcoholics. This I would consider to be the weaker side of defending abstinence. 4. What are some of the strengths associated with the Con side of the issue? What are some of the weaknesses? Strength: I read the section and I really am having a hard time coming up with the strengths of this side. I guess I could say that there are a few people who CLAIM to be alcoholics, who can drink moderately. I personally believe they were never alcoholics to begin with. Weakness: Just because a few people can drink reasonably, doesn’t mean it should be taught to alcoholics. 5. How credible were the authors of each argument? Explain your answer. Owen holds her doctoral and masters degrees in adult clinical psychology and a M. H. A. degree in health care administration from the University of Minnesota. She has also published numerous articles on chemical dependency and has given presentations at many national conferences. She was the director of Butler Center for research and Education at the Hazelden Institute in Center City, Minnesota (Moyers, n. d. ). Her passion for helping people with addictions started well over 20 years ago. Owen thought she would train for three months; learn a little about addiction in a psychiatric hospital, and then move on to a private practice (Moyers, n. d. ). The three months would change her life forever. Owen learned that people with addiction could really change, unlike other mental illnesses. People could live a normal life free from medication, with the help of other addicts and a higher spiritual power. This fascinated Owen (Moyers, n. d. ). So after reading Owens back ground I believe she is the most creditable in the area of abstinence. It is the area of study that Owen has dedicated her life to. 6. Based on the statements presented in this critical issue, which author do you agree with? Why? Dr. Owens side makes more sense to me. I also personal believe in abstinence. I have been married to two different alcoholics. Both men tried many programs to stay sober. The only program that worked the longest for both men was abstinence. Once they had a beer they could not stop. One husband would start by drinking one beer and could not stop until he passed out. The other man would start by drinking a beer or two a night and over a few weeks it would worsen until someone got hurt, always me! I have known to many friends and family members who abstinence from alcohol was the only way. I told my ex husband that I truly believed it was harder for me to lose weight than for him to stop drinking. He could try to stop drinking, but if I stopped eating I would literally die. Living with just eating a little is extremely hard! 1. Which side of this critical issue does contemporary research support? Please provide specific examples in your response. | | Currently abstinence is the side that contemporary researcher’s support. | | |The 12 step program has been in the past and still continues to be the most | | |successful and popular program for an alcoholic.

Cuban Missile Crisis Essays (2640 words) - International Relations

Cuban Missile Crisis John F. Kennedy's greatest triumph as President of the United States came in 1962, as the world's two largest superpowers, the Soviet Union and the United States, edged closer and closer to nuclear war. The Soviet premier of Russia was caught arming Fidel Castro with nuclear weapons. The confrontation left the world in fear for thirteen long days, with the life of the world on the line. In 1962, Nikita Khrushchev, Premier of the Soviet Union, employed a daring gambit. He secretly ordered the placement of Soviet nuclear weapons in Cuba. Earlier the Soviet premier had promised Soviet protection to Cuba (Cuban 774). This was the first time any such weapons had been placed outside of Eurasia (Hersh 345). Several explanations for his actions have been offered by historians. One factor in Khrushchev's decision was a strategic one (Hersh 346). A year earlier, the United States had placed several medium-range nuclear missiles in Turkey (Cuban 774). The missiles were just across the Black Sea from the Soviet Union, within sight of Khrushchev's summer home (Hersh 346). President Kennedy had earlier ignored his advisors and placed nuclear missiles in Turkey. Another factor was a threat by the US to one of the Soviet Union's satellite countries, Cuba (Hersh 346). The United States had, in the past, attempted to kill Fidel Castro, dictator of Cuba (Brinkley 1047). In July of 1962, the United States found out that nuclear missile shipments were being made to Cuba. United States U-2 spy planes flew over the island, bringing back reports of construction and ballistic missiles (Cuban 744). The CIA found that five thousand Russian military technicians were in Cuba, and various military weapons were being unloaded onto the island. When U-2 activity was increased, reports showed the presence of SAMs (surface-to-air missiles) and torpedo boats with ship-to-ship rockets (Mills 233). On September 4, Soviet ambassador Anatoly Dobrynin met with Robert Kennedy to discuss a message from Khrushchev. According to the message, the military buildup was defensive in nature and not militarily threatening. Robert F. Kennedy informed the ambassador that the United States would closely watch all military activity in Cuba and warned of severe consequences should the Soviets place offensive weapons (Mills 233). President Kennedy apparently did not believe the message. He asked Congress for the authority to mobilize over 100,000 reservists into active duty. The Soviets response was that they could fire rockets from Russia just as easily as from Cuba. Offensive missiles in Cuba, they argued, were therefore unnecessary for an offensive base(Mills 234). Furthermore, the United States had over 3,000 nuclear warheads and nearly 300 missile launchers, opposed to the Soviet Union's 250 warheads and 24 to 44 missile launchers (Hersh 343). Still, John Kennedy thought that Cuba could become a base for military operations at any given moment. The United States had to be prepared to face it (Mills 234). At this point in the crisis, John McCone, the CIA director, was regularly sending President Kennedy reports of missiles capable of launching a nuclear warhead being sent to Cuba. According to McCone, medium-range ballistic missiles(MRBMs) would be next (Hersh 348). U-2's were sent to scout the west end of Cuba. On October 14, the CIA reported that construction had begun for MRBMs (Mills 235). Despite the increased state of readiness in the US, many people did not realize that the Soviet Union had done nothing on its home territory during the crisis. Its fleet of ICBM launchers were not mobilized and neither were Soviet reserves. There were not even any threats against Berlin (Hersh 343). Regardless of what the Soviets said, the United States was still far ahead in the nuclear arms race. ICBM's were expensive to build and the Soviet Union did not have an abundance of money. Installing the smaller missiles in Cuba was much cheaper than building more ICBMs. Khrushchev believed that Kennedy would not oppose the building of the missile bases in Cuba because the United States President had not opposed Khrushchev in the past (Mills 236). Not only did he secretly place the missiles in Cuba, but Khrushchev used Georgi Bolshakov and others to tell President Kennedy that missiles were not being shipped to Cuba. The Soviet premier was cautious to avoid a

System Implementation Essay Example | Topics and Well Written Essays - 750 words

System Implementation - Essay Example All the different types of users have limited privileges for their data as well as other users’ data. For example, the customer can only view but cannot insert, delete, or update their information. Consequently, that makes our system more secure. The principle involved designing very simple web pages for all the users. These simple pages view served the security features that were used. For example, the page shows three choices for them that are accessing their data, or customer data or transaction data. That occurs if the user is an employee. If the user selects their information, the page displays a table with the user’s information only. However, the pages that are designed to look for the customer contains two input fields to search for the client based on their id or first name. For instance, if the Employee wants to look for their customer’s information. In this situation, we applied the feature of a prepared statement and variable binding in Java JDBC component in order to avoid any vulnerability in our project. The system also applied this principle. There were no standard mechanisms for our users that will cause extreme effects. Every user has his mechanism, privilege, and flow. The Manager works differently from the employee or the customer. Moreover, we created users in the database for each category. Thus, the user who uses the database as manager1 is different from manager2. The concept is taken care in the attack phase. We exposed the system designs and security mechanisms to other teams. That helped us a lot because it is better to know about the System’s weaknesses and vulnerabilities from friends before the attackers. In this situation, we can fix and update the missing points and errors quickly. Further, we don’t need to batch after the attacker misusing.

Impact of World War II on the United States Essay

Impact of World War II on the United States - Essay Example Prior to the war, the New Deal was not able to overcome the stagnant state of the US economy despite the concerted efforts of the Roosevelt government. The unemployment rate remained steadily above 14 percent despite having considerably fallen since the darkest years of the depression. A consideration of a more penetrative government fiscal intervention gave way to speculations about real economic recovery in which it was posited that the recovery would become elusive if given to the care of the private sector (Vatter 1985, p. 7). Such recovery required much more Keynesian doses for the New Deal to finally affect full employment (Vatter 1985, p.11). Political impacts include several pursuits that aimed to repair a damaged economy during the New Deal era and the war itself. A political, psychological, and economic shift was a product of the New Deal and World War II in the United States. These concerns troubled the American government during the war years and immediately afterward: big government, the economy, and communism at home and abroad. It was inferred that the bourgeoning bureaucracy that ensued in the United States during the WWII was one characterized by the mounting of commissions, agencies, and administrations, aiming to serve the legal and political necessities of the period. Examples of these are the Foreign Economic Administration, Maritime Commissions and the War Shipping Administration, Selective Service System, US Employment Service, War Manpower Commission, War Labor Board, and War Food Administration (Vatter 1985, p. 87). Each of these had their on designated purposes in which central is the organizing and carrying out of American war-time economic production and output. All of these bureaucratic organizations formed a government front aiming to push through all forms of opposition in the interest of allied victory. The War Production Board (WPB) was established in order to distribute strategic materials as well as suspend the production of consumer products. The WMC attempted to balance the appropriat e distribution of men and women in military, industry, and agriculture during the war (Maddox 1992, p. 193). There was no questioning that the United States placed itself in a hegemonic position as a world power after the war, which may be referred to as one of its political impacts. Likewise, America's preoccupation with the promotion of democracy is essentially an idealist stance that emerged from the moralism and exceptionalism of the America political tradition (Ikenberry 2000, p. 103). This tradition is manifested through actual foreign policy, often carried out at the expense of more sober American international interests (Ikenberry 2000, p. 103). It is for the pursuit of making foreign policy commitments more acceptable to American public that the American democratic stance becomes a minor distraction. The American promotion of democracy after World War II reflects a pragmatic and evolving understanding of creating a stable political order in the international arena, which was later called "an American liberal grand strategy"

Forklift Accident Article Example | Topics and Well Written Essays - 500 words

Forklift Accident - Article Example An accident occurred at the construction site of a light industrial building. A worker was driving a 3 ton forklift down a circular vehicle ramp from the fourth level towards the third level. There was no load on the forklift. The vehicle suddenly swerved and overturned on the third level and the worker who was driving the forklift was crushed beneath the vehicle and died on the spot. The driver had not undergone the mandatory forklift driver’s training course. Findings revealed that the forklift involved in the accident belonged to the main contractor and was poorly maintained. The driver was an employee of the plastering and bricklaying works contractor. The numbers of trained forklift operators were inadequate with respect to the number of forklifts. Also there was no risk assessment conducted on forklift operations.Another such accident occurred at a warehouse in a distribution park. A worker tallying stock stored on metal racks squeezed himself into the gap between two ra cks. A forklift driver was pushing racks closer together to make space for more racks. He did not see the employee, and the employee was crushed to death between the metal racks. If risk assessment had been carried out, forklifts and other workers would not have been allowed to operate in the area concurrently. It also seemed that there was inadequate safety training awareness among the employees.The key to preventing such accidents is training and enforcement of safety measures at places where forklifts are used.

Constructivist and Liberalist Argument on State Shared Value

Constructivist and Liberalist Argument on State Shared Value According to realism, relations between states in the anarchical world is doomed to the state of constant conflict in which states can only count on themselves. Whatever cooperation exists in the world they prescribe it to the hegemonic order. This means that hegemon, creates institutions which facilitate cooperation but that these institutions are carriers of hegemonic interests and their existence is related to the existence of a hegemon. Representatives of liberal school deny the abovementioned argument and point at contemporary networks of cooperation in many fields which they see as a positive current in the world politic. Realists and liberals agree that the status of international system is anarchy and sovereign states make up the international order. As Alexander Wendt stated in 1992 in his article[1]: neorealists and neoliberals share generally similar assumptions about agents: states are the dominant actors in the system and they define security in self-interested terms[2]. As for the Liberals, they underline the importance of international institutions and cooperation between states thus placing a principle of the shared values in the center of state-behavior. Constructivist Argument According to Alexander Wendt, concept of power politics is socially constructed: If self-help is not a constitutive feature of anarchy, it must emerge casually from processes in which anarchy plays only a permissive role. This reflects a second principle of constructivism: that the meanings in terms of which action is organized arise out of interaction[3] Wendt views self-help as something not given by nature but instead, socially constructed. Having in mind the fact that power politics is socially constructed means that it can be transformed by human practice. Furthermore, constructivists look at international arena as a constructed structure which is built by socio-cultural practices, ideas, domestic and international interactions. According to Wendt, the basic tenets of constructivism are the structures of human association that are determined primarily by shared ideas rather than material forces, and that the identities and interests of purposive actors are constructed by these s hared ideas rather than given by nature[4]. According to the theory of constructivism the effect of anarchy on the state is proportionate to the states perception of anarchy, identity and interest. If in the state of Anarchy state A perceives the rise of power of state B as threat to its security, then a security dilemma is created and states apply to the self-help principle. But, if state A and state B view their security in the form of cooperation and collaboration, then a security dilemma is not formed, thus not establishing logical grounds for self-help principle to develop. Alexander Wendt in his article anarchy is what state make of it: The social construction of power politics states that: the nature of international anarchy appears to be conflictual if states show a conflictual behaviour towards each other, and cooperative if they behave cooperatively towards one another. Therefore, it is states themselves that determine anarchys nature.[5] Liberal argument Representatives of liberal theory agree with realists on a notion that international system is anarchical. But unlike realist, liberalism mitigates the risks coming from the nature of anarchy with cooperation and collaboration between states.[6]. While liberalism agrees on an anarchical condition of international politics, it provides three main mechanisms that can explain a state behavior in order to avoid the risks coming from the anarchy: consolidation of democracy, economic interdependence, and transtational institutions.[7] In order to mitigate the threats and risks coming from the anarchy representatives of the liberal theory believe that states should become more interdependent with each other. Shared democratic values and economical interdependence significantly reduces the risk of military confrontation between states. Free trade relations between states, which result in a close economic ties between its citizens, excludes the chance of military confrontation with each other. According to Michael W. Doyle: Wars occur outside the liberal zone because conflicts of interest are deeper there.[8] Liberalism also allows a probability of the world peace despite the anarchical feature of international politics. If the state behavior is prone to establishment of international organizations and institutions then this behavior may lead to the long term cooperation between the member nations which share the same values. According to the liberalism military conflicts are not inevitable but can be prevented through collaboration. The development of an international organization such as United of Nation, NATO and European Union are the examples of cooperation between states that could promote stability. A central claim of this theory is that once created, institutions tend to persist, because it is cheaper to maintain institutions than to create new ones. Therefore, when confronted with new sets of problems, states seek to modify an already existing institution to meet new challenges. Thus, institutional liberal theories have easier time explaining why NATO persisted after the end of the Cold War even when the enemy that it was supposed to counter disappeared. Liberalism underlines the significace of the shared values between states. The principle of shared values can explain state behavior as they create alliances and develop joint capabilities, rather than focusing only on the development of their own.

Emancipation :: essays research papers

Emancipation has been defined as the pursuit, expansion, and security of freedom. I believe that most people including myself would say successful emancipation has taken place when freedom has been pursued, expanded upon, and secured. What makes peoples views of emancipation different is not its definition, but what is freedom? Freedom shows a lot of faces throughout the times and environments studied in both the Haitian and Jamaican Revolutions. Freedom for myself is a peace of mind. I feel that a person who wakes up with a peace of mind has experienced successful emancipation. Successful emancipation does not mean that everything is perfect and the way it should be. Perfection does not exist in this world; everything has its flaws and downfalls including emancipation, justice, and freedom. I think we all work towards the day we have established who we are and find comfort with our role in society. I also feel it is hard for us to be as thoughtful and passionate about emancipation as the slaves of these times were. Our minds can’t conceive the true feeling of what is like to be treated like something other than a human being. I feel our lifestyles are far beyond a slave’s view of what emancipation is. Slaves in both Haiti and Jamaica did not rebel in order to live a lifestyle we live today. They were willing to settle for far less than we have today. Slaves were willing to die in order to experience what they felt was successful emancipation. Successful emancipation for slaves was not be confounded to land or owned by whites. Slaves simply wanted the opportunity to work their own land, start families, and enjoy life. Although most people in Haiti and Jamaica of African descent were slaves, there was a small minority of free people, which consisted of mulattos and free blacks. Even though these free people witnessed first hand the experienced of slavery the compassion and empathy for it was definitely disappointing. Their understanding of emancipation was totally different than that of slaves. The free people already experienced and had what slaves desired and viewed as emancipation. Free people had their own land to farm, build houses on, and start families. Thus giving them a totally different perspective on emancipation and freedom. Despite free people had their own land, they still were not close to sharing the same rights as the whites.

Reservoir Dogs

Reservoir Dogs Postmodernism theory when related to films can be described when the audience’s delay of skepticism is shattered, in order to free the audience’s grasp of the director’s work. Small changes are made to create a significant meaning in the audience’s mind. The director has created a piece of art that removes the audience from the conventional and emotional bond to the subject, creating a new perspective.Postmodern films apply the usage of four concepts: simulation, reusing styles, typically drawing irony to the new style; pre-fabrication, drawing a closer attention to already existing scenes and using them in the films narrative or dialogue; intertextuality, using text that has already been used and finally bricolage, creating a film based on a collage of various other film styles and genres. Quentin Tarantino, the famous film director, screenwriter, producer, cinematographer and actor followed his passion from an early age. He did not watch m ovies as a child and adolescent, but he made the films a large part of his life.Tarantino, though he may deny his films to fall in the category of postmodernism, portrays various genres and styles from other movies, typically of his childhood very well. Tarantino draws upon the genres of martial arts, kung fu, grind-house, and spaghetti western films. Typically starting his films, Tarantino opens with â€Å"Our Feature Presentation† drawing immediate attention to the audience, transporting them in time to their days of childhood and adolescents. A director is an artist, Tarantino, though he recreated previous works of other artists, is one too.He adds his own twist to his films, in order to create a new, distinctive and pioneering film. Tarantino uses the concept of bricolage to fuse genres together in an original fantasy-like story with exaggerated confrontation scenes and violence. Reservoir Dogs, directed and written by Quentin Tarantino first premiered in October 1992. It is about a group of criminals who where hired for a job to retrieve diamonds from a jewelry store. Things do not go as planned during the heist and the gang thinks that there may be a police mole among the group. But who could it be? Mr. Pink, Mr. Orange, Mr.White, Mr. Brown, Mr. Blue, Mr. Blonde, Nice Guy Eddie, or even head gang leader, Joe Cabot? Strangers to one another, Joe (Lawrence Tierney) assigns each member a color code alias. The opening scene is in a diner with all gang members sitting around a table, eating breakfast, while Mr. Brown (Quentin Tarantino) explains his interpretation of Madonna’s song ‘Like a Virgin’. The men continue to discuss the importance and the meanings of popular songs, especially bringing up songs of the 1970s. Though this dialogue is rather unimportant, it shows Tarantino’s intricate eye to detail.It is ironic to see Tarantino the one explaining Madonna’s song, for it is his intention to set the stage for the au dience’s interpretation of the film. Mr. Brown explains Madonna’s sexual encounters, as she continues to remember the first time she lost her virginity and the pain she had to encounter. Tarantino intends for Reservoir Dogs to have many interpretations, and one may consider that the gang members have to be redeemed through pain and suffering. The styles that we can see throughout the film use exaggerated confrontations and violence.After the diner scene, the film continues with a â€Å"Men in Black† take of the gangsters walking towards the camera. Mr. White (Harvey Keitel) and Mr. Orange (Tim Roth) are now on pursuit away from the heist, as things did not go as planned as the cops showed up unexpectedly. Running on foot, they stop a car and the owner and driver shoots Mr. Orange in the abdomen. For the remainder of the film, Mr. Orange laid on the floor of the warehouse bleeding profusely in excruciating pain. The pain that Mr. Orange faced throughout the film is the interpretation that Tarantino had intended to compare to the suffering of Madonna.Mr. Orange (Roth) was the undercover mole that was ordered to bust the head of operation, Joe Cabot (Tierney). Aside for Tarantino’s significance of popular songs, he also used images inter-dispersed throughout the film; Silver Surfer comic and the Get Christie Love! TV show. These are a few examples of how Reservoir Dogs falls into the category of being a postmodern film through the usage of image and text, posing as in intricate part to media and society. Reservoir Dogs, a postmodern film, includes the usage of criminals falling; indicating a crime and gangster movie.It also uses the formula of a western movie. Though, usually in a traditional western there is one individual who upholds law and order, Tarantino put a spin on western genres when including the style throughout his films. Reservoir Dogs use of western is slightly different, instead of one individual; there is a group of me n who try to restore order that has spun out of control to arrange a logical explanation and conclusion of who the possible informant might be. Tarantino is specific about his films, he does not intend for them to represent real life, but rather mimic other movies.In Reservoir Dogs initial scene, the men are sitting in the diner, a very similar scene to Woody Allen’s film Hannah and Her Sisters (1986) when they are sitting in a restaurant. Woody’s film is considered to be a romantic comedy drama, where Tarantino, though not considering Woody when creating the scene, did not create a romantic comedy drama film, but rather a film that fell into the category of crime, mystery and thriller. Quentin Tarantino pulls from previous artists, not only text and images, but also styles, such as cinematography. In Reservoir Dogs, Tarantino uses extreme conflict and intense violent scenes.Aside from the acting, Tarantino creates a character, Mr. Pink (Steve Buscemi), who is constant ly reminding the team that he is acting professional, while everyone else is fighting and not thinking of the future affects of their actions. Mr. Pink aside from being a â€Å"better† criminal, draws upon the belief that if you are not wearing a uniform you therefore fall into the â€Å"real person† category. Tarantino, throughout all his films, Reservoir Dogs, Pulp Fiction (1996) and Kill Bill (2003; 2004) the assassins, criminals, and law enforcements are all distinguished by their uniforms.Those who are â€Å"real people† wear real, daily, regular clothing, nothing that is out of the ordinary. The gang members who work for Joe Cabot are all dressed in the classic black suits with white button down dress shirts and thin black ties. The cops are wearing the typical blue uniform. It is interesting to notice that Joe and his son, though apart of the gang operation do not wear the â€Å"uniform†. The majority of Reservoir Dogs takes place in the dingy ware house, where no gangster becomes a â€Å"real person†; they do not undress from their uniforms, therefore staying as a gangster.Though they do not succeed in becoming real people, they are redeemed of being a gangster through death, unlike Mr. Pink who runs out after they go on a â€Å"trigger happy frenzy† shooting one another. The idea of the members, including the cop that was taken hostage is a similar idea to William Shakespeare, who was considered an outstanding poet and playwright during the 16th century. Typically, at the end of the plays, Shakespeare would conclude that the characters all be killed. Tarantino, a rather outstanding director and writer, pulls from these great artists to create an even greater piece of work.Quentin Tarantino, considered a postmodern filmmaker, uses references to earlier films. He blends genres from A-Z. In Reservoir Dogs, he uses many references from the French new wave directors, who were highly influential to his Production Com pany as well as his work. Francois Truffaut and Jean-Luc Godard were influential; he named his production company â€Å"A Band Apart†. In Reservoir Dogs, Tarantino named the jewelry store â€Å"Karina’s† after Anna Karina, star from Bande apart (Band of Outsiders, 1964).Postmodernism is a concept that pulls from many genres, and it is Reservoir Dogs that Quentin Tarantino first begins his voyage as an up and coming director to use this style of creativity and expression. Today, we entertain ourselves with concerts, movie theater, broadways, radio, and television. It is these social medias that people like Quentin Tarantino create for our enjoyment. Pulling on our childhood memories, familiarity, comfort, and most importantly clues to other important images of our past, bring a deeper appreciation to the work and creativity that has been produced.

High School vs College 15 Key Differences

High School vs College 15 Key Differences SAT / ACT Prep Online Guides and Tips Are you about to start college soon? Are you wondering what changes to expect? How is college different from high school?When you compare high school vs college, you’ll find many differences, some of which are obvious, others less so. It’s important to understand how high school and college are different from each other so you know what to expect and can have a smoother transition when you begin college.In this guide, we explain the 15 most important differences between high school and college and give you tips to help make this major life change a bit less intimidating. How Is College Different From High School? There’s a reason so many movies, shows, and books focus on new college students: many people see the transition from high school to college as one of the most important turning points in their life.You’re no longer a kid living under your parents’ roof; instead you’re an adult living on your own and expected to make real, important decisions about your future. You’ll have a lot more freedom, but a lot will also be expected from you, both in class and out. Read on to learn specific high school vs college differences. High School vs College: 15 Key Differences Below are 15 high school vs college differences you’ll likely encounter once you begin college. There are pros and cons to both high school and college, but knowing what to expect will make you better prepared for this big change. #1: You’ll Have More Independence The biggest change for high school vs. college is that, in college, you’ll have much more independence than you had in high school. Many people focus on the fact that you’ll be living away from your parents, and this is a part of it, but you’ll have independence in many other areas as well. You’ll have the freedom to decide what you want to major in, which classes you want to take, when you want to schedule those classes, if you want to go out with your friends, how late you want to stay out, even what you want to eat in the dining hall. (I ate Reese’s Puffs cereal every day for four years because my parents never allowed it and I was thrilled to finally be able to have it for breakfast.) #2: You’ll Be Treated Like an Adult Along with your increased independence, you’ll also be treated like an adult in college as opposed to a child under your parents’ care. In college, you’ll no longer need to bring your parents permission slips to sign, you’ll be trusted to make your own choices for what you want to study, and you can arrange meetings yourself, without Mom and Dad helping you. For many students, it’s exciting to finally be viewed as an adult, but it also means an increase in responsibilities. If you have a problem with or question about homework, classes, a grade you got, etc.,you are the one who will need to solve it. You can’t expect your parents to call the school and fix the problem for you like they may have done in high school. #3: There Will Be a Wider Variety of Classes to Choose From In high school, you didn’t have a lot of choice in regards to which classes you took. You could probably choose a few electives, but your schedule was mostly filled with the standard math, science, English, and social studies requirements that all students had to take. In college, even if you attend a smaller school, you’ll have many more options. They’ll be a wider variety of classes to choose from, and many of them will focus on more specific topics like astronomy, ancient Roman history, French literature, the geography of the United States, and more.Many college students like this increase in class options since it makes it easier for them to choose classes on topics they’re really interested in. #4: Classes Will Have Different Formats and Sizes Each class you took in high school probably had about the same number of students and consisted mostly of lecturing, maybe along with some individual or group work. This isn’t true in college.Classes can range from two to 500 students, and their format can vary widely as well. Classes may be completely lecture-based, require hands-on lab work, or be discussion-based where you spend most of class time engaged in conversations or debates with your classmates and professor. #5: Your Schedule Will Be More Complicated In high school, school started and ended the same time every day, and your class schedule was probably the same for every day of the week.In college, things get a little trickier. Some classes meet three times a week for an hour and a half, some meet five times a week for an hour, some meet once a week for three hours, etc.This means you’ll likely be starting and ending class at different times during the week, and you may end up with a different class schedule for every day of the week. Some people like the variety this gives them, but it’s important to stay on top of your schedule so you don’t wind up forgetting to attend class. #6: You’ll Have a New Set of Classmates One of the most jarring things for many new college students is they’re no longer surrounded by classmates and friends they’ve known for years. Instead, you’ll be in a sea of strangers (at least at first), many of whom come from different areas and backgrounds than you. Additionally, you'll likely have a different set of classmates for each of your classes. That's a lot of new faces! This means you have lots of opportunity for making all kinds of friends, but expect there to be some awkwardness and loneliness at first as everyone gets to know each other and figures out their friend groups.Additionally, since in college everyone wants to be there (at least on some level), you may find your college classmates more motivated and dedicated to doing well in school compared to some of your high school peers. #7: Classes Will Require More Critical Thinking Is college hard compared to high school? Going to college isn’t just like attending four more years of high school. This is a big step up in your education, and your classes will be more challenging and expect you to keep up.You’ll be tested less on memorization and basic regurgitation of facts and more on critical thinking skills and being able to apply what you learned in class to other situations. You may learn a specific math equation and then be asked to apply that knowledge to more challenging types of equations, learn about different historical events and be asked to analyze how they affected future events, learn a scientific process and be asked to describe how it affects the environment, etc. #8: College Costs More There’s no way around it; college definitely costs more than high school. Tuition is thousands of dollars, and you’ll likely be paying for room and board as well. And those are just the main costs. College requires all sorts of smaller purchases too, like special goggles for your chemistry lab or official test taking booklets for final exams. Buying just one college textbook (often over $100) is enough to never let you take for granted all free materials you got in high school. #9: You’ll Spend Less Time in Class Most full-time college students spend about 15-20 hours in class a week, which comes out to about three or four hours a day. This is probably much less time than you spent in high school classes every day which means you’ll have a lot more unscheduled time to spend how you think is best. #10: You’ll Have More Schoolwork Don’t get too excited about spending less time in class; college definitely knows how to keep you busy. The general rule of thumb is that you’ll spend about three hours a week on schoolwork for every one hour of class you’re in. With a standard schedule of 15 credits, that means you can expect to spend 45 hours a week on schoolwork, about as much as a full-time job!This is often much more work than students had in high school, so you should be prepared for an adjustment. #: Attendance Will Be Up to You In high school, you had to go to class every day because if you didn’t, you could get in trouble for truancy or (sometimes even more frightening) your parents could find out.In college, there are no requirements for attending class, and no one is going to call your parents if you don’t show up.However, don’t make the mistake some college students do and think this means you don’t need to go to class. Many professors include attendance as part of your grade, and some will even fail you if you miss a certain number of classes without a valid excuse. Plus, it’s often very difficult to do well in a class if you never show up, and you’re paying a lot of money for these classes! Make sure you get the most out of them that you can. #12: You’ll Have More Social Opportunities Even if you were a social butterfly in high school, you’ll have tons more opportunities to be social and make friends in college. There will be sports teams to join, parties to go to, clubs you can be part of, and more.Most colleges are large enough to have something for everyone, so you’re bound to find an activity you’re interested in, whether that’s a recreational hockey team, the student government group, a club focused on promoting renewable energy, and more. There are also likely many more students at your college than there were at your high school, so your opportunities for making friends will multiply as well. However, you do need to make an effort to get the most out of these opportunities. Push yourself to try new things and strike up conversations with new people, and if you're feeling nervous, just remember that they're likely feeling the same way. Standard questions to ask new people you meet in college include: Where are you from? What dorm do you live in? What are you majoring in? Get ready to ask and be asked these questions a lot! #13: It’ll Be Harder to Stand Out Once you start college, you won’t be a big fish in a small pond anymore, and it’ll be harder to stand out from the crowd.While in high school you may have been the star student/athlete/singer, in college you’ll be surrounded by many talented classmates, many of whom were also the best at something in high school.Some students struggle with no longer automatically standing out, but there are plenty of benefits to this. First, you’ll be able to bond with other students who are also skilled at your talent. If you were, say, the star drama student at your high school, you may not hold the same position in college, but you can befriend all the other high school drama stars and create some awesome shows together. Additionally, some students like the anonymity being a new college student brings. If you’ve been labelled as a jock or theater nerd for all of high school, going to collegewhere people don’t know youallows you to shed or alter that identity if you wish and try new things (or try the same things with less pressure). #14: You’ll Get Fewer Grades in Class In high school, you probably had daily homework assignments you had to complete and got a grade for. These, along with some larger projects, quizzes, and tests made up your final class grade. If you got a low score in one, it was usually fine since there were plenty of other chances to make up for the low grade. Once you start college, you may find that many classes have far fewer assignments, meaning you’ll receive fewer grades and each of those grades are worth more.Instead of regular homework assignments and quizzes, many college classes are based only on a midterm grade and a final grade. This means you need to take those exams/papers/projects very seriously because if you mess up on one of them it’ll be very hard to raise your class grade back to where you want it to be. #15: You’ll Be Doing Lots of Reading You know those pictures of exhausted-looking students sitting next to a pile of textbooks they need to get through? That’s how many college students feel.Expect to do lots of reading in college, including textbooks, journal articles, and literature.If you’re majoring in a field like computer science or math you can expect less reading (and more homework), but you’re still guaranteed to have at least a few classes where you’re assigned to read a couple dozen textbook pages before the next class. You’ll get to know your school’s library very well. Tips for Making the Transition From High School to College Going from high school to college can be tough no matter how excited you are to start at your new school. Below are three tips to help make the transition easier. Know There Will Be Changes You’ve already taken one of the most important steps to prepare for transitioning from high school to college: you’re expecting and preparing for the differences.When you know that the high school to college transition will bring major changes, you'll be more prepared for anything that comes your way. Be Prepared for Some Bumps Many movies about college make it seem like new college students immediately find a group of close friends, know exactly what they want to study, and have an awesome social life. In reality, it rarely works like this.Many new college students have moments where they feel awkward, lonely, and homesick. This is completely normal; after all you’re making a major life change. By managing your expectations of college and not expecting to love it right away, you can better manage the transition from high school to college and not end up disappointed when it takes a little while to feel comfortable. Put Yourself Out There When you first start college, there will be a lot of changes, and it’ll be easy to hang out in your dorm room and text with your high school friends. However, you should resist this urge. College is probably the best time you’ll ever have to meet new people and try new things, so you should take full advantage. Keep your dorm room door open to meet your neighbors. Strike up a conversation with your chemistry lab partner. Join a club or sport you’ve never tried before.Not only will this make the transition from high school to college easier since you’ll be meeting more people, you may discover a new friend or hobby.

Joseph Conrads Heart of Darkness essays

Joseph Conrads Heart of Darkness essays In Joseph Conrad's novel, "Heart of Darkness," we can easily see how the environment can have a negative impact on an individual's mental health. By examining the character of Kurtz, we can see how easily this occurs. We are told by Marlow that Kurtz is "gifted" (Conrad 1902 p. 294) and when Kurtz arrived in the jungle, his "sympathies were in the right place" (p. 295). However, after years of living in an elevated state above the natives, he began to lose his respect for life as well as his sanity. The natives worshipped him and he had the "power to charm and frighten rudimentary souls into an aggravated witch-dance in his honor" (p. 296). This illustrates how he began to actually believe he was as great as the natives thought he was. This inflated self opinion was the beginning of In addition, Kurtz was only interested in obtaining more ivory. We read that after years of living alone, he "wandered alone far in the depths of the forest" (p. 301). In addition, he would "disappear for weeks; forget himself amongst the people" (p. 302) to hunt for more ivory. This illustrates how he became more isolated from people, which also attributed Eventually, Kurtz lost his ability to reason because he was obsessed with ivory and because he was alone more and more. In fact, Kurtz threatened to shoot his dearest friend if he did not give Kurtz his ivory. We are told that Kurtz "declared he would shoot me unless I gave him the ivory and then cleared out of the country, because he could do so . . . and there was nothing on earth to prevent him from killing whom he jolly well pleased" (p. 301). Additionally, Kurtz kept a collection of shrunken heads on stakes near his house. (p. 303) We are told that these heads "only showed that Mr. Kurtz lacked restraint in the gratification of his various lusts" (p. 303). This demonstrates Kurtz's complete lack of respect for ...

Managing People 2 Essay Example | Topics and Well Written Essays - 750 words

Managing People 2 - Essay Example In addition, flexible working reduces stress level, which increases the productivity of an employee. Many companies big and small are also increasingly adopting flexible working schedules. This is because research has showed that flexible working increases workers productivity thus revenue. Therefore, since the main aim of a company is to increase productivity of workers so as to generate high profits, none would want to be left behind. In this regard, Regus (2012, p.3) reveals that about 80% of small companies report working more flexibly than before. At the same time, Regus (2012, p.3) found out that 68% of large businesses today provide flexible working to their employees. It was also found out that about 72% of international businesses reported having realized increased productivity as a result of flexible working. However, in all cases, Ragus (2012, p.3) reveals that about 68% of businesses reported that flexible working has increased staff productivity. About 63% of companies s urveyed indicated that flexible working increased their workers energy and motivation level pointing that flexible working is principal talent-retention technique. Research also indicates that about 51% of companies intend to employee more freelancers in the future (Ragus 2012, p.3). At the same time, about 80% of companies interviewed believe that there is a likelihood of an increase in the number of employees willing to work part-time, which points at an increasing demand for an environment that allows for flexible working. There are a number of companies in the U.K. that have embraced flexible working practices. BT (formerly British Telecommunications) is one such company in London that provides flexible working environment. BT is one of the largest Information technology and telecommunication companies in the U.K. Since the U.K. government legislated a law to improve flexible working, BT has embraced the practice in totality. The flexible working of BT is based on a number of pr inciples regarding service delivery, recruitment, and motivation. BT acknowledges the fact that many workers have the responsibility of taking care of others such as the elderly, children, the disabled, and the sick. The company also recognizes the fact that, with UK’s aging population, such demand is likely to increase, which will also increase competition for workers throughout the U.K. As a result, many candidates will likely be looking at what employers offering terms of flexible working in deciding on the company to work for (Eurofound 2009). As a result, BT has introduced a number of flexible working practices, which includes compressed time, job-sharing, accrual hours, annualized hours, flexitime, limited working, time out, teleworking and freedom to work. BT reports having reaped a lot of benefits from such a working practice. In this regard, BT reports that flexibility has increased the motivation level of its employees, which has in turn increased their productivity . As a result, the company has been able to register increased profits than ever before (Eurofound 2009).

Module 5 SLP - Assignment Example The merger of the two companies will lead to the growth of this small company by increasing the economic demand. Hershey Company will benefit from diversification. The risks of investments spread by adding other sectors. Secondly, KONZA Company has a high liquidity. As the liquidity hypothesis stipulates, an increase in liquidity leads to an increase in in merger this is because it makes it possible for Hershey Company to acquire and finance the acquisition by use of resources (McDonald et al., 2006). KONZA Company faces a major threat of mismanagement of firm’s resources by managers to maximize the shareholders wealth. Therefore, if the two companies merge, the resources would effectively managed to maximize on the shareholders wealth as well as profit maximization of the company. I would finance the takeover by selling the company shares. This is by public invitation to buy the shares at premium from the shareholders of the company. This will enable the company to raise enough funds for growth and investments. My second choice would have been Texas Company because the company has a high debt that is attractive and not used. This will is an avenue to merge as low leverage reduces the default risk and increases the debt volume for the joint company (Vachon, 2007). The company investments have a positive net present value (NPV) meaning that it can invest in and gain profits. The two companies therefore can merge and invest in projects that yield profits, as it is a major goal of the company. This company could not be the first choice because it is a bit stable and does not suffer from liquidity and mismanagement of firms resources. My third company would be INOVA Company that is a stable company, operating under ongoing concern and is of large size. The company would merge with Hershey to benefit from synergies. The financial mathematics shows that the

Un Chien Andalou by Salvador Dali and Luis Bunuel Essay

Un Chien Andalou by Salvador Dali and Luis Bunuel - Essay Example The purpose of paper "Un Chien Andalou by Salvador Dali and Luis Bunuel" is to investigate how the corresponding philosophical position of postmodernism influences the aesthetic values of the work of art, the film Un Chien Andalou. Surrealism, which is a part of the philosophy of postmodernism is defined as psychic automatism in its pure state, by which one expresses verbally by means of the written word, or in another manner, the actual functioning of thought. Surrealism is dictated by the thought, in the absence of any control exercised by reason, and devoid of aesthetic or moral concern. Surrealism is based on the belief in the superior reality â€Å"of certain forms of previously neglected associations, in the omnipotence of dream, in the disinterested play of thought†. It ruins completely all other psychic mechanisms and substitutes itself for them, while solving all the main problems of life. The postmodern philosophy challenges any clear and concise process of identific ation and definition as a part of rationality. Postmodernism rejects common sense and accessibility, scientific reason, philosophical logic, clarity or precision. On the other hand, postmodernism seeks to grasp those elements that escape these processes of definition, and â€Å"celebrates what resists or disrupts them†. A plurality of definitions has now come to describe postmodernism’s multifaceted nature. Examples of postmodern art relate to fracturing, fragmenting, indeterminacy and plurality. Postmodernism is the style of our age.

Example a Level Psychology Experiment Essay Example for Free

Example a Level Psychology Experiment Essay Hypothesis – there will be a significant positive relationship between the scores on a memory test and scored on a test to predict your chance of being a millionaire Null Hypothesis – there will be no significant relationship between scores on a memory test and scores on a test measuring the chances of becoming a millionaire and any relationship is due to chance Method: Design – the method of the experiment was a correlational study; this was used in order to see whether there was a relationship between the scores on a memory test and scores on a millionaire test. The experiment used co variables, which were the score on the memory test and score on the millionaire test. Controls – in order ensure the test was reliable the extraneous variables needed to be controlled. Standardised instructions were used as a control to give all participants the same instructions during the experiment, which meant that the experimenter did not affect the communication of the instructions by changing them for each participant which reduces the amount on experimenter bias. A further control that was used was using anonymous data by assigning each participant a number to record that data on a table, rather than using individual’s names. Participants – the target population for the experiment were young people in the Gosport area of each gender. The sampling method was an opportunity sample of 10 students aged 17-18 both males and females (2 males and 8 females) at Bay House Sixth Form from an A Level Psychology class and the researcher was a Psychology teacher at Bay House Sixth Form. Apparatus and Materials – the materials used for the experiment were a list of 34 words created by the researcher that were projected onto the board, paper and pens provided for the participants to record the number of words they remembered, a watch to time the one minute period of remembering and writing down the words, an online questionnaire to measure likelihood of becoming a millionaire at bbc.co.uk/science/humanbody/surveys/millionaire1/index.shtml Procedure – the participants were firstly given an explanation of the research and what the study would entail for them. They were them given the equipment they required to complete the memory test whilst remaining anonymous and were given standardise instructions by the researcher of how to complete the test and the rules of the research. The participants were then shown the list of 34 words to memorise by projecting the list on the board and where given one minute to memorise as many words as possible. The words were then hidden and the researcher projected instructions to the participants to write down all the words they remembered and they were given one minute to do so. The number of words memorised were recorded by the researcher by assigning each participant with a number and they stated out loud their score. The participants were then asked to move to a computer room to complete an online survey to test their likelihood of becoming a millionaire, after they completed the questionnaire the participants had to record their score next to their memory score on a board. The participants were then debriefed by the researcher. Ethics – there were few ethical issues in the experiment as informed consent was gained by the researcher to ensure the participants were given instructions and the aim of the research. Therefore, there was no deception in the research and so the integrity of the study was intact during the memory and millionaire tests. Furthermore, all the participants were over 16 and so there was no need for the researcher to obtain parental consent for the study. Participants were also given the right to withdraw before and during the research, therefore the participants were not pressured to take part or complete the study if they were not comfortable with the terms of the research or what the data was being used for. However, there may be ethical issues regarding the wellbeing of the participants during the research as the study may have caused stress or anxiety in the participants when completing the memory or millionaire tests because they may feel the pressure to do well in each test, although the research was anonymous and so this may have reduced the amount of stress caused by the study. Scatter Graph for Data: The scatter graph shows that there is a weak negative correlation between memory test scores and millionaire test scores, which means that it does not necessrily prove our hypothesis that there will be a significant postive relationship between the two co variables. Therefore, the hypothesis needs to be rejected and the null hypothesis can be accepted as the null hypotehsis reflects what our results show on the scatter graph. The graph can also help identify outliers, as the partipant that scored significantly higher on the memory test and lower on this millionaire test could be regarded as an outlier as it does not follow the pattern of the other data found from the research. Evaluation: Design – the design that was used in this research was correlational, which is good as allows us to identify if there is a relationship between two co variables as well as allowing research to be conducted that cannot be done in a lab experiment as is would not be viable. However, correlational studies do not show cause and effect between the two co variables and so it cannot be stated that having a good memory will cause a person to become a millionaire in the future as it could just as easily be that being a millionaire causes a person to have a good memory. Sample – the sample that as used in this study was very small, as only 10 people took part in the research; also the participants were psychology students. Therefore due to the small sample and the specific type of participant the results may not be able to be generalised to the wider population. Furthermore, gender may have been an issue with the sample as there were only 2 males, whereas there were 8 females, therefore there was not an equal mix of each gender and so the results cannot be generalised. Tests – the tests that were used in the study were a memory test created by the researcher and an online questionnaire to predict that chance that the participants would have of becoming a millionaire. The memory test was good as it used standardised instructions, meaning that the test was more reliable as the same instructions were shown to all participants at the same time, which reduces the amount on researcher bias and means that participants can query any confusion they have. Moreover, the standardise instructions mean that there is high control in the research and so the results are reliable. The millionaire test may have had some issues as the closed questions that were used may have not provided an applicable answer, resulting in participants answering questions incorrectly which may have an effect on the results.

Numerical Differential Equation Analysis Package

Numerical Differential Equation Analysis Package The Numerical Differential Equation Analysis package combines functionality for analyzing differential equations using Butcher trees, Gaussian quadrature, and Newton-Cotes quadrature. Butcher Runge-Kutta methods are useful for numerically solving certain types of ordinary differential equations. Deriving high-order Runge-Kutta methods is no easy task, however. There are several reasons for this. The first difficulty is in finding the so-called order conditions. These are nonlinear equations in the coefficients for the method that must be satisfied to make the error in the method of order O (hn) for some integer n where h is the step size. The second difficulty is in solving these equations. Besides being nonlinear, there is generally no unique solution, and many heuristics and simplifying assumptions are usually made. Finally, there is the problem of combinatorial explosion. For a twelfth-order method there are 7813 order conditions! This package performs the first task: finding the order conditions that must be satisfied. The result is expressed in terms of unknown coefficients aij, bj, and ci. The s-stage Runge-Kutta method to advance from x to x+h is then where Sums of the elements in the rows of the matrix [aij] occur repeatedly in the conditions imposed on aij and bj. In recognition of this and as a notational convenience it is usual to introduce the coefficients ci and the definition This definition is referred to as the row-sum condition and is the first in a sequence of row-simplifying conditions. If aij=0 for all i≠¤j the method is explicit; that is, each of the Yi (x+h) is defined in terms of previously computed values. If the matrix [aij] is not strictly lower triangular, the method is implicit and requires the solution of a (generally nonlinear) system of equations for each timestep. A diagonally implicit method has aij=0 for all i There are several ways to express the order conditions. If the number of stages s is specified as a positive integer, the order conditions are expressed in terms of sums of explicit terms. If the number of stages is specified as a symbol, the order conditions will involve symbolic sums. If the number of stages is not specified at all, the order conditions will be expressed in stage-independent tensor notation. In addition to the matrix a and the vectors b and c, this notation involves the vector e, which is composed of all ones. This notation has two distinct advantages: it is independent of the number of stages s and it is independent of the particular Runge-Kutta method. For further details of the theory see the references. ai,j the coefficient of f(Yj(x)) in the formula for Yi(x) of the method bj the coefficient of f(Yj(x)) in the formula for Y(x) of the method ci a notational convenience for aij e a notational convenience for the vector (1, 1, 1, ) Notation used by functions for Butcher. RungeKuttaOrderConditions[p,s] give a list of the order conditions that any s-stage Runge-Kutta method of order p must satisfy ButcherPrincipalError[p,s] give a list of the order p+1 terms appearing in the Taylor series expansion of the error for an order-p, s-stage Runge-Kutta method RungeKuttaOrderConditions[p], ButcherPrincipalError[p] give the result in stage-independent tensor notation Functions associated with the order conditions of Runge-Kutta methods. ButcherRowSum specify whether the row-sum conditions for the ci should be explicitly included in the list of order conditions ButcherSimplify specify whether to apply Butchers row and column simplifying assumptions Some options for RungeKuttaOrderConditions. This gives the number of order conditions for each order up through order 10. Notice the combinatorial explosion. In[2]:= Out[2]= This gives the order conditions that must be satisfied by any first-order, 3-stage Runge-Kutta method, explicitly including the row-sum conditions. In[3]:= Out[3]= These are the order conditions that must be satisfied by any second-order, 3-stage Runge-Kutta method. Here the row-sum conditions are not included. In[4]:= Out[4]= It should be noted that the sums involved on the left-hand sides of the order conditions will be left in symbolic form and not expanded if the number of stages is left as a symbolic argument. This will greatly simplify the results for high-order, many-stage methods. An even more compact form results if you do not specify the number of stages at all and the answer is given in tensor form. These are the order conditions that must be satisfied by any second-order, s-stage method. In[5]:= Out[5]= Replacing s by 3 gives the same result asRungeKuttaOrderConditions. In[6]:= Out[6]= These are the order conditions that must be satisfied by any second-order method. This uses tensor notation. The vector e is a vector of ones whose length is the number of stages. In[7]:= Out[7]= The tensor notation can likewise be expanded to give the conditions in full. In[8]:= Out[8]= These are the principal error coefficients for any third-order method. In[9]:= Out[9]= This is a bound on the local error of any third-order method in the limit as h approaches 0, normalized to eliminate the effects of the ODE. In[10]:= Out[10]= Here are the order conditions that must be satisfied by any fourth-order, 1-stage Runge-Kutta method. Note that there is no possible way for these order conditions to be satisfied; there need to be more stages (the second argument must be larger) for there to be sufficiently many unknowns to satisfy all of the conditions. In[11]:= Out[11]= RungeKuttaMethod specify the type of Runge-Kutta method for which order conditions are being sought Explicit a setting for the option RungeKuttaMethod specifying that the order conditions are to be for an explicit Runge-Kutta method DiagonallyImplicit a setting for the option RungeKuttaMethod specifying that the order conditions are to be for a diagonally implicit Runge-Kutta method Implicit a setting for the option RungeKuttaMethod specifying that the order conditions are to be for an implicit Runge-Kutta method $RungeKuttaMethod a global variable whose value can be set to Explicit, DiagonallyImplicit, or Implicit Controlling the type of Runge-Kutta method in RungeKuttaOrderConditions and related functions. RungeKuttaOrderConditions and certain related functions have the option RungeKuttaMethod with default setting $RungeKuttaMethod. Normally you will want to determine the Runge-Kutta method being considered by setting $RungeKuttaMethod to one of Implicit, DiagonallyImplicit, and Explicit, but you can specify an option setting or even change the default for an individual function. These are the order conditions that must be satisfied by any second-order, 3-stage diagonally implicit Runge-Kutta method. In[12]:= Out[12]= An alternative (but less efficient) way to get a diagonally implicit method is to force a to be lower triangular by replacing upper-triangular elements with 0. In[13]:= Out[13]= These are the order conditions that must be satisfied by any third-order, 2-stage explicit Runge-Kutta method. The contradiction in the order conditions indicates that no such method is possible, a result which holds for any explicit Runge-Kutta method when the number of stages is less than the order. In[14]:= Out[14]= ButcherColumnConditions[p,s] give the column simplifying conditions up to and including order p for s stages ButcherRowConditions[p,s] give the row simplifying conditions up to and including order p for s stages ButcherQuadratureConditions[p,s] give the quadrature conditions up to and including order p for s stages ButcherColumnConditions[p], ButcherRowConditions[p], etc. give the result in stage-independent tensor notation More functions associated with the order conditions of Runge-Kutta methods. Butcher showed that the number and complexity of the order conditions can be reduced considerably at high orders by the adoption of so-called simplifying assumptions. For example, this reduction can be accomplished by adopting sufficient row and column simplifying assumptions and quadrature-type order conditions. The option ButcherSimplify in RungeKuttaOrderConditions can be used to determine these automatically. These are the column simplifying conditions up to order 4. In[15]:= Out[15]= These are the row simplifying conditions up to order 4. In[16]:= Out[16]= These are the quadrature conditions up to order 4. In[17]:= Out[17]= Trees are fundamental objects in Butchers formalism. They yield both the derivative in a power series expansion of a Runge-Kutta method and the related order constraint on the coefficients. This package provides a number of functions related to Butcher trees. f the elementary symbol used in the representation of Butcher trees ButcherTrees[p] give a list, partitioned by order, of the trees for any Runge-Kutta method of order p ButcherTreeSimplify[p,,] give the set of trees through order p that are not reduced by Butchers simplifying assumptions, assuming that the quadrature conditions through order p, the row simplifying conditions through order , and the column simplifying conditions through order all hold. The result is grouped by order, starting with the first nonvanishing trees ButcherTreeCount[p] give a list of the number of trees through order p ButcherTreeQ[tree] give True if the tree or list of trees tree is valid functional syntax, and False otherwise Constructing and enumerating Butcher trees. This gives the trees that are needed for any third-order method. The trees are represented in a functional form in terms of the elementary symbol f. In[18]:= Out[18]= This tests the validity of the syntax of two trees. Butcher trees must be constructed using multiplication, exponentiation or application of the function f. In[19]:= Out[19]= This evaluates the number of trees at each order through order 10. The result is equivalent to Out[2] but the calculation is much more efficient since it does not actually involve constructing order conditions or trees. In[20]:= Out[20]= The previous result can be used to calculate the total number of trees required at each order through order10. In[21]:= Out[21]= The number of constraints for a method using row and column simplifying assumptions depends upon the number of stages. ButcherTreeSimplify gives the Butcher trees that are not reduced assuming that these assumptions hold. This gives the additional trees that are necessary for a fourth-order method assuming that the quadrature conditions through order 4 and the row and column simplifying assumptions of order 1 hold. The result is a single tree of order 4 (which corresponds to a single fourth-order condition). In[22]:= Out[22]= It is often useful to be able to visualize a tree or forest of trees graphically. For example, depicting trees yields insight, which can in turn be used to aid in the construction of Runge-Kutta methods. ButcherPlot[tree] give a plot of the tree tree ButcherPlot[{tree1,tree2,}] give an array of plots of the trees in the forest {tree1, tree2,} Drawing Butcher trees. ButcherPlotColumns specify the number of columns in the GraphicsGrid plot of a list of trees ButcherPlotLabel specify a list of plot labels to be used to label the nodes of the plot ButcherPlotNodeSize specify a scaling factor for the nodes of the trees in the plot ButcherPlotRootSize specify a scaling factor for the highlighting of the root of each tree in the plot; a zero value does not highlight roots Options to ButcherPlot. This plots and labels the trees through order 4. In[23]:= Out[23]= In addition to generating and drawing Butcher trees, many functions are provided for measuring and manipulating them. For a complete description of the importance of these functions, see Butcher. ButcherHeight[tree] give the height of the tree tree ButcherWidth[tree] give the width of the tree tree ButcherOrder[tree] give the order, or number of vertices, of the tree tree ButcherAlpha[tree] give the number of ways of labeling the vertices of the tree tree with a totally ordered set of labels such that if (m, n) is an edge, then m ButcherBeta[tree] give the number of ways of labeling the tree tree with ButcherOrder[tree]-1 distinct labels such that the root is not labeled, but every other vertex is labeled ButcherBeta[n,tree] give the number of ways of labeling n of the vertices of the tree with n distinct labels such that every leaf is labeled and the root is not labeled ButcherBetaBar[tree] give the number of ways of labeling the tree tree with ButcherOrder[tree] distinct labels such that every node, including the root, is labeled ButcherBetaBar[n,tree] give the number of ways of labeling n of the vertices of the tree with n distinct labels such that every leaf is labeled ButcherGamma[tree] give the density of the tree tree; the reciprocal of the density is the right-hand side of the order condition imposed by tree ButcherPhi[tree,s] give the weight of the tree tree; the weight (tree) is the left-hand side of the order condition imposed by tree ButcherPhi[tree] give (tree) using tensor notation ButcherSigma[tree] give the order of the symmetry group of isomorphisms of the tree tree with itself Other functions associated with Butcher trees. This gives the order of the tree f[f[f[f] f^2]]. In[24]:= Out[24]= This gives the density of the tree f[f[f[f] f^2]]. In[25]:= Out[25]= This gives the elementary weight function imposed by f[f[f[f] f^2]] for an s-stage method. In[26]:= Out[26]= The subscript notation is a formatting device and the subscripts are really just the indexed variable NumericalDifferentialEquationAnalysis`Private`$i. In[27]:= Out[27]//FullForm= It is also possible to obtain solutions to the order conditions using Solve and related functions. Many issues related to the construction Runge-Kutta methods using this package can be found in Sofroniou. The article also contains details concerning algorithms used in Butcher.m and discusses applications. Gaussian Quadrature As one of its methods, the Mathematica function NIntegrate uses a fairly sophisticated Gauss-Kronrod-based algorithm. The Gaussian quadrature functionality provided in Numerical Differential Equation Analysis allows you to easily study some of the theory behind ordinary Gaussian quadrature which is a little less sophisticated. The basic idea behind Gaussian quadrature is to approximate the value if an integral as a linear combination of values of the integrand evaluated at specific points: Since there are 2n free parameters to be chosen (both the abscissas xi and the weights wi) and since both integration and the sum are linear operations, you can expect to be able to make the formula correct for all polynomials of degree less than about 2n. In addition to knowing what the optimal abscissas and weights are, it is often desirable to know how large the error in the approximation will be. This package allows you to answer both of these questions. GaussianQuadratureWeights[n,a,b] give a list of the pairs (xi, wi) to machine precision for quadrature on the interval a to b GaussianQuadratureError[n,f,a,b] give the error to machine precision GaussianQuadratureWeights[n,a,b,prec] give a list of the pairs (xi, wi) to precision prec GaussianQuadratureError[n,f,a,b,prec] give the error to precision prec Finding formulas for Gaussian quadrature. This gives the abscissas and weights for the five-point Gaussian quadrature formula on the interval (-3, 7). In[2]:= Out[2]= Here is the error in that formula. Unfortunately it involves the tenth derivative of f at an unknown point so you dont really know what the error itself is. In[3]:= Out[3]= You can see that the error decreases rapidly with the length of the interval. In[4]:= Out[4]= Newton-Cotes As one of its methods, the Mathematica function NIntegrate uses a fairly sophisticated Gauss-Kronrod based algorithm. Other types of quadrature formulas exist, each with their own advantages. For example, Gaussian quadrature uses values of the integrand at oddly spaced abscissas. If you want to integrate a function presented in tabular form at equally spaced abscissas, it wont work very well. An alternative is to use Newton-Cotes quadrature. The basic idea behind Newton-Cotes quadrature is to approximate the value of an integral as a linear combination of values of the integrand evaluated at equally spaced points: In addition, there is the question of whether or not to include the end points in the sum. If they are included, the quadrature formula is referred to as a closed formula. If not, it is an open formula. If the formula is open there is some ambiguity as to where the first abscissa is to be placed. The open formulas given in this package have the first abscissa one half step from the lower end point. Since there are n free parameters to be chosen (the weights) and since both integration and the sum are linear operations, you can expect to be able to make the formula correct for all polynomials of degree less than about n. In addition to knowing what the weights are, it is often desi
