Amos and Hosea Essay

Amos was a Judean who believed he was commissioned by Yahweh to address his words to Israel, However Hosea was a native Israelite. With these two men was the custom of recording oracles which appear to have begun, for if the words of their prophetic predecessors were preserved in a written form, then they would have long since been lost to us all. Within a few years, prophets sharing similar concerns with Amos and Hosea began to be active in Judah and their words too, were preserved. II Kings 15 and Amos 1-9 Amos stood in judgment of moral and ethical evil but, unlike them, he did not limit himself to single issues or to individual situations, but dealt with the decline of Yahwism and human behavior in all levels of society. Cities he mentions), patterns of cause and effect (3:3 ff.), and Israelite cult practices. His vivid imagery, drawn from nature, suggests an intelligent observer capable of relating his insights and experiences in powerful terminology. Perhaps the very simplicity of his life caused him to be shocked at the extravagances of the rich and the terrible poverty and helplessness of those who were the prey of the powerful. The luxury of summer and winter palaces as opposed to the hovels of the poor, the greedy demand of the very rich contrasted with the cry for justice and equity of the underprivileged drove him to harsh pronouncements against powerful, smug, content men and women, priests and king. The thrust of Amos’ condemnation is against the division of life into compartments. He argues for unity. What a man does in the market place, in the Court of law or, in his dealings with others cannot be walled off from worship. Yahweh is a God of all people; therefore the dealings of man with man are directly related to the dealings of God with man. His is a cry for the recognition of man’s moral responsibility before God. â€Å"But let justice roll down like waters and righteousness like an Overflowing stream.† Amos 5:24 AMOS’ RELIGIOUS CONCEPTS Amos’ beliefs concerning Yahweh and divine-human relationships were similar. Yahweh the creator, the â€Å"God of hosts† Amos never speaks of Yahweh as â€Å"God of Israel†), or possessed power over nature and nations. Despite the unrealistic emphasis, Yahweh’s particular concern was Israel, the chosen or  elected people, Amos emphasized Yahweh’s action in history in bringing the Hebrews to nationhood and greatness, and pointed out that the continuance of power and security rested in Yahweh.

Comparing and Contrast curriculum models

Comparing and Contrast curriculum models In early childhood education, we model our programs after highly respected models such as, Montessori, High Scope, and Reggie Emilia, Creative Curriculum, etc. We all have our own approaches to education. In the following paragraphs I will summarize two curriculum models, compare and contrast two of the curriculum models and compare the one that best matches my own educational philosophy.High/Scope curriculum is based on Piaget's concept that children are asctive learners who construct their knowledge base through playing and experimenting ith hands-on materials (Segal, Bardige, Wolka, ; Leinfelder, 2006). This curriculum framework describes educational ideas and strategies but does not rely on a specific set of materials.The five basic principles that form the framework of the Hlgh/Scope Curriculum are active learning, supportive adult-child interactions, a materials-rich learning environment, a consistent daily routine, and ongoing child ass essment. The Hlgh/Scope educational programming Includes the following elements: a core curriculum that includes specific elements but encourages following children's nterests, a three-phase â€Å"plan-do-review† learning cycle, and assessment tools and strategies (Follarl, 2007).

The American Journalist Robert Kaplan stated that anyone who Essay

The American Journalist Robert Kaplan stated that anyone who disbelieves Hobbes' state of nature argument has never visited Co - Essay Example One of the most famous journalists from America, Robert Kaplan has attributed such a term to the society of Cote da’Ivoire, also called in English has the Ivory Coast. To make a statement of such magnitude, there must be some sense going behind it. And indeed, when one sees the current crisis in the Ivory Coast on both the social and political fronts, one is ought to come to the conclusion that Hobbes description of ‘state of nature’ is still prevalent. (Volkov 2011) The troubled lands of West Africa saw an unusual development in political and societal fronts through the land of Ivory Coast. After its independence from the French in 1960, there was a line of hope within the minds of people of this country to stand tall amongst other nations. But, it all came down when the first political crisis rose in Abidjan in 2002. Irrespective of the presence of the French troupes in the country, deployed primarily to seize any such rebellions against the government, the poli tical scenario was split into two with the rebels occupying the entire northern half of the country. When the United Nations came into picture, a deal was struck wherein the rebels, the Ivorians and the ruling government would combine together to form a united governance.

Take one contemporary film of your choice and critically analyze how Essay

Take one contemporary film of your choice and critically analyze how it might be considered postmodern - Essay Example Post-modernist films are characterized by self-referentiality, pastiche, intertextuality, and parody (Hill 2000, p.93). The features of post-modernist films may be identified in a film’s plot, casting/characterization, form, or visual theme. Post-modernist films may also play like a collage of stereotypes and tropes and may mix different types of media. A closer analysis of the film Kick Ass helps to identify its integrated postmodernist traits. The film Kick Ass provides a fine parody of superhero films and the genre. The film comments ironically on the superhero genre and the conventions it encompasses. It has spoof written all over it. Frederic Jameson (1988, p.15), identifies both the use of Pastiche and parody as a significant characteristic in post-modernist art. He notes that â€Å"one of the most significant features or practices in postmodernism today is pastiche† (Jameson 1988, p15). He notes that both pastiche and parody involve the mimicry of other styles and particularly the stylistic twitches of other styles. In her article, Linda Hutcheon argues that post-modernism main interest is parody. She references the use of parody in postmodern architecture to stress her point by stating â€Å"parodic references to the history of architecture textually reinstate a dialogue with the past and inescapably with the social and ideological context in which architecture is and has been both produced and lived† (Hutcheon 1986, p.181). Kick-Ass pokes fun at the entire superhero genre. The film encompasses its parody through the humor it employs within key stages that demystify the invincibility of a superhero. For example, the film parodies from the superhero film Spider-Man. While Spider-Man is able to take giant leaps across buildings, Kick-Ass almost attempts to do the same but inescapably gets terrified and retaliates. Unlike in other superhero films where the

Further Education in UK - Essay Example Some FECs are funded directly; others receive money indirectly through a franchise agreement with a higher education institution, or as part of a consortium. Contact details and links to further information on FECs providing HE courses are available through the HERO web-site. The following list gives the 135 FECs that we are funding directly I am proud that my first White Paper as Secretary of State should be on the issue of education for our 14 to 19 year old.(http://195.194.167.100/unicoll/FE/). The reforms set out for further education are very much important. They are vital to UK economy equipping young people with the skills employers' need and the ability to go on learning throughout their lives. Reforms are vital for social justice giving us the chance to give break through the historic link between social back ground, educational achievement and life chances that have determined UK citizens as a nation. And most of all these are vital to each and every individual young person, whatever the needs of the young people or whatever they want to be. Young teenagers are tomorrow's leaders, entrepreneurs, parent and community servants, so we should take a special care for the children in the age group of 14 to 19; it is the age period when one needs guidance and help for selecting one's career. Build a system of 14 to 19 education that will do just that. A system that we can be proud of. And one that gives every young person the opportunities they need and deserve. Every child and every teenager has equal worth. We owe it to them to give them the chance to show what they can do, to make the most of their talents, to reach their potential. And the key to doing that is to design a system around them based on high standards, on choice and on meeting individuals' needs and aspirations. To deliver that system will take determination. It will take commitment. It will take the hard work of teachers, lecturers, other education professionals, employers, parents and all who work in or with our schools and colleges. It will require breaking down the artificial barriers between academic and vocational education. It will mean building on all that is good in our system and reforming what is not working. Building from the excellent work of Sir Mike Tomlinson and his Working Group on 14-19 Reform and from the work of the successful school and college partnerships we are already seeing in local communities. It charts a 10-year reform programme and the milestone s needed to achieve it. But more than those details and those milestones, it sets out a vision of what we want for children and teenagers what we want them to learn, the skills we want them to acquire, but above all the values we want them to have. The purpose of the education system is to help each and every individual reach their potential.

Consider the mediatisation of warfare. Does the rise of social media Essay

Consider the mediatisation of warfare. Does the rise of social media change the ability of western military to control perceptio - Essay Example The government resources and power was no match for the hordes of people which were notified through the social media about where and when to meet for rallies and demonstrations. The Egyptian civil war was known as the Facebook Revolution, largely in recognition for the huge role of Facebook and the social media on the turnout of the war in the favor of the majority of Facebook users. This is a phenomenon which would likely be repeated in the future. There have already been incidents when the media and the social media has had an impact on warfare, so much so that it has also affected the western ability to control the perceptions of contemporary conflicts. This essay shall discuss this point further, seeking to answer how the rise of social media change the ability of western military to control perceptions of contemporary conflicts. This essay shall argue that the rise of the social media has decreased the ability of the western military to control perceptions of contemporary confl icts, especially in relation to how these wars are fought, how necessary or unnecessary they may be, how long they are fought, and in what favor the wars should end. Initially, a general overview of the impact of the social media on warfare will be discussed. This shall include a discussion on key theories related to the subject matter. This shall be followed by a discussion of various incidents where the social media has impacted on warfare in different parts of the world. The latter part shall then relate the impact of the social media on how the western military has been able to control (or not control) the perceptions of contemporary conflicts. B. Body In considering the theories discussed during this course, the media determinism theory is likely the closest theory which would help explain the impact of the social media on warfare and the outcomes of warfare (Chandler, 1995). The theory discusses how the media seems to imply a direction in opinions and actions which is not with in the cultural or political influence. There is a belief in this case that the media has a strong governing impact on society. It impacts on how individuals think and how they relate with each other. It drives social progress and innovation. This theory declares that media impacts significantly on society and it can have a significant cause and effect relationship with society (Chandler, 1995). Media technologies, including the social media can bring about change in society. This theory is a simplistic assessment of complicated situations, with cause and effect relations decreased to their lowest premise, sometimes managed in those conditions. Innis and McLuhan have applied this theory as they declare how the media can shape a person’s and society’s self-perception as well as realization (Chandler, 1995). In general, this theory highlights the fact that the media can impact significantly on how society and technology can impact on the general population. In this case, the social media is an innovation of the media. It is a new aspect of media relations which is also having a similar impact on society and how they understand, perceive, and conceptualize information. In other words, the theory supports the notion that the social

Economic Impacts of Tourism Essay Example | Topics and Well Written Essays - 1250 words

Economic Impacts of Tourism - Essay Example The economic impacts in the tourism sector immediately ask for grants, loans and stipends to be given to the people who have an indirect or for that matter direct role in the building up of structures, buildings, and pathways – all of which come under the tourist attraction cycle. (Jafari, 2000) The economy gets a facelift and there are changes in the lines of commerce and industry since the country realizes its true potential elsewhere. Consequently, people come to terms with the advancements and technological changes that start to happen within such lands and thus hail the efforts undertaken by the related ministries. It builds a bridge between the different publics which are playing an active role in this impacting cause – tourism development and management within a country. The publics comprise of the locals who would be more than willing to offer hotel/motel services, transport facilities and the like; as well as the foreigners which come towards this region in ord er to enjoy and learn a bit more about the scenery. Tourism is a vast field that has immense economic advantages. The need is to understand the right kinds of interactivity regimes and reject the negative image and propaganda, however, it is wise and in the best interest of building public relations that the government and the authorities always speak unanimously the truth that exists. Shortcomings related to the region and the problems that could happen for the tourists must be educated in advance so that the tourists are given a choice as per their respective undertakings and journeys. The effects of tourism on the region are apparent but what it brings to the country’s foreign reserves is important. It opens up the path that leads towards success since the government finds out the cash cow – the tourism industry.

Human resources Essay Example | Topics and Well Written Essays - 500 words - 3

Human resources - Essay Example Current competitive environment has made employees more devoted towards their work and they end up having issues with their personal life (Friedman 2008). Various relationships have experienced breakups due to increased devotion towards work by either one or both members of the couples. Due to problems in personal life, organizations end up paying higher costs (Beard 2011). Researchers have proven that increase in work-life imbalance has resulted in high employee turnover rate, increase in number of days when employees are absent from work, health issues, dissatisfaction from job and life, and increased pressure on managers (Imam 8644). All of these problems are directly linked with decrease in productivity of an organization. When the rate of employee turnover increases, work is halted until empty positions are filled (Beard 2011). When employees do not attend work, the amount of production that they would have been able to conduct is compromised. Dissatisfaction from working condit ions results in de-motivating the workers to work efficiently and effectively, which decreases the quality and the quantity of goods produced. The organizations do not only face loss of productivity due to work life imbalance, they even end up paying higher cost incurred for employee’s psychological health, which is disturbed by this imbalance. Various ways have been continuously pointed out to solve the problem of work-life imbalance; managers need to assess these ways and create programs constituting these methods to increase productivity and increase work-life balance. Managers can offer flexible work timings to employees, for example, managers have to allot a specific number of hours for an employee to work and the employee can decide what bracket of hours he choose to work (Kanter 2010). Managers can assign a work day of 5 hours to an employee and the employee can choose whether to work from 9am to 2pm or 2pm to 7pm etc.

WHAT IS MEANT BY STIGMA,AND DOES IT LINK WITH THE CONCEPT OF SOCIAL Essay

WHAT IS MEANT BY STIGMA,AND DOES IT LINK WITH THE CONCEPT OF SOCIAL EXCLUSIONS AND WHAT ARE THE IMPLICATIONS FOR POLICY AND PRACTICE - Essay Example In this regard, social labelling that discredits individuals’ virtual identities (Crocker et al 1998, p.505), inevitably leads to stigmatization that often times leads to distortion of individual identities. Social exclusion, on the other hand, refers to the state of being locked out from participation in the central social activities in one’s own society (Burchardt et al 2002, p.30); this means that if an individual fails to take part in social activities then they are ‘socially excluded’. The purpose of this paper is to explain what is meant by the term ‘stigma’, and to explore the possible linkage there is between this term and the concept of social exclusion; consequently, the conclusion of this paper will draw upon this knowledge to give implications for policy and practice. Simply put, stigma denotes ‘a mark of shame’ (Oxford Dictionaries, 2012), concomitant particularly with certain individuals in the society, thus, people who are stigmatized actually view themselves inferior due to social labels that describe them so, distorting their real identities. According to Chamberlin, stigma often leads to discrimination implying that the individual being stigmatized has a problem (Sayce 1998, pp.331-332); in this case, language is a powerful tool that functions in the creation of certain perceptions and stereotypes about individuals. When people make biased judgments concerning others, this negative labelling coupled with the resultant social labels and subsequent stigmatization that arises can be attributable to mental health issues. Language is very effective in helping people with mental illnesses to manage and eventually overcome their problem especially because the words used in reference to people influence their perceptions and expectatio ns respectively (Lynn 2010 p.1). For instance, existing knowledge shows that relapse rates of patients with mental

Reaction paper for international studies lectures Essay

Reaction paper for international studies lectures - Essay Example The relationship between the economy and globalization is only based on positive impacts and change. While defining globalization, Norberg (2003) points out that globalization is a way in which nations can share the same platform of trade with minimized legal and corporate requirements. He regards this definition as the main reason behind the development of many nations from underdeveloped countries to developed and developing countries. Apart from economic growth, globalization has led to many other positive changes in the modern society. Norberg (2003) cites gender equality, improved education and a more efficient way of fighting global crimes such as terrorism as other significant changes impacted by globalization. In his arguments and theories, Held & McGraw (2007) argue that globalization creates a united globe that greatly depends on each other for excellence. Norberg (2003) creates well formulated defensive arguments in support of globalization. In his arguments, he acknowledges the most important positive changes globalization has impacted in the global front (Norberg, 2003). He cites significant reduction of poverty and hunger across the globe as one major importance of globalization (Norberg, 2003). With globalization, poverty and hunger are effectively addressed as global bodies and nations have steeped up the efforts to eradicate the two problems. Additionally, Norberg (2003) argues that globalization has increased the level and spread of democracy. Across the globe people have the freedom of speech and decision making regardless of the cultural or social affiliations. Kalder (2000) also points out that the increased gender equality can be attributed to the rising levels of globalization. Kalder (2003) also depicts globalization with positive perception. The most important argument in her literary piece is that globalization is the answer to wars experienced across the globe. She points out that

Effects of gambling Essay Example for Free

Effects of gambling Essay Most people with gambling problems say they lost control over how much time and money they spend gambling. Meanwhile, they ignored other responsibilities. For them, gambling is an activity that are important to them. Those who gamble excessively often bring problems for the one they love. The effects of gambling can be classified into individuals, family and the society. Each of them had different aspect. With the problems that been brought by those gamblers, they brought many troubles to many peoples. They considered as an ignoble person. The effects that affected an individual are normally harm themselves. Once a gambler lose in a gamble, they will become anxious and unhappy, and often hate themselves very much. Therefore, they will do something stupid like borrow money from those loan sharks, commit suicide and even involved in some criminal cases such as robbery, murder, etc. The urge of gamble is hard to resists because of the reason they win continuosly. Once they won one time, they will continue to gamble to win more to satisfy their satisfaction. If once they lose, they will not give up easily due to they cannot accept the fact they had lose and scared to be a loser. Therefore, they will never give up any chance to gamble if there are just an uncertain chance to win. Some people still believe their system will pay off, their luck will change or they are due to win. Some people promised to quit gamble, but they cannot, but they afraid their love one will find them out. This drives them into fear and further into debt. In addition to, a gambler will also harm themselves because of gambling. All the gamblers face different problems, mainly like divorce, debt collection by those loan sharks, suffer from illness, many hassles in different aspects. Other than individuals, there are effects that affected family. Gambling problems hurt families in many ways, such as money problems. Money problems defined as family members that knew that savings, property or belongings have been lost, it can make them feel angry, betrayed and anxious. Through this problem, it caused family breakdown and caused the children to be in a single parent family. By the way, gamble will cause emotional problems and isolation. Gambling problems cause strong feelings among family members, which make it harder to solve problems. The partners of those gambler that is with problems do not want to get close with them because they the gambler hurt them. Due to this problem, it caused divorce and break up. In other hand, family members will avoid from other people because they felt ashamed of their family member that gamble excessively and they had been backstabbed by many people. Physical and mental health is another effect. The stress of gambling problems sometimes causes health problems. A person that gamble excessively will had health problems, same to their family members. This included anxiety, depression and stress-related problems like insomnia, ulcer, headaches and many illness that will strongly impact their health. Burnout also is one of the effect that affected a personal. Many families under stress have trouble coping. They often cope cause of money and the family member dislike the gambler. The gambler keep on taking more tasks will lead to burnout too. Once the plan that the gambler planned had fail, this will lead to causing problems. Family members often forget to take care themselves or to have fun. Gambling will bring great impacts on children. A family that with a gambler parent that with gamble problem will always let the children feel forgotten, depressed and anxious. The parent gamble all the time, therefore they will not put more attention on their children but on gamble. Some children may stop trusting their parents due to the unfaithfulness, but some children may draw attention away from the parent with gambling problem by misbehaving. Nowadays, the society also been affected by the problems of gambling. The unsteady of economic is one of the reason. Due to the bankruptcy of a personal will affected the economic growth. In addition, during the time of economic success, casinos tend to take labour supply away from neighbouring business. Casinos offer higher wages, hence many employees from other business such as restaurant, saloon will leave the neighbouring business and work for casinos. Customers that are normally went to the restaurant now instead go to the casino for foods. This demonstrates how not all growth by a casino can be attributed as economic growth, sometimes casinos merely transfer growth from other businesses into their own. It would never dawn on them that the casino itself would never pay out more than it brings in. There would not be many people are lucky enough to win big, maybe just one in a million. The others are just donating money to their cause. On the extreme side, people have committed suicide because their lives have totally been turned upside down due to the addiction. Due to commit suicide, the society might lose some genius, talents to develop the country. In addition, gambling will cause our country to be in a extinct situation because of gambling, therefore will affected family problems. Due to bankruptcy, it caused many people to face unemployment and because of this, it will affect the growth of economic. Once the gamblers put all their efforts into gambling, it will affect their working efficiency. When they had addicted to gambling, they will not have the effort to work. It will greatly affect the firm businesses, therefore the head of the firm will remove the post of the gambler and asked the worker to resign by themselves. Because of this, it caused many unemployment in the country. There are few ways that building a casino could result in no increased benefits for the region. Examples like, local residents who used to go to restaurants now spend their money in the casino. Then the casino has no net economic benefit. Other than this, tourists who used to spend money on other activities within the region now go to a gambling facility within the region. In addition, to have many casinos in our country, it will greatly affected neighbouring business. Locally-owned businesses go bankrupt because consumers have changed their expenditures to casinos that happen to be owned by out-of-state interests. A casino buy more products from out of state than the businesses they replace, therefore it had brought great impact to the local business. Besides that, Casinos result in increased social costs including police and other public services as well as the costs of pathological and problem gamblers. These issues will be addressed shortly. This will affect the tourism in a same time.

Prediction Of Cutting Forces In Broaching Operation Commerce Essay

Prediction Of Cutting Forces In Broaching Operation Commerce Essay According to variety of workpiece profiles in broaching, the geometry of cutting edge varies from simple line to very complicated curves. Wide range of cutting edge geometry in broaching imposes complexity to the distribution of the chip load along the cutting edge. Hence, prediction of cutting forces in broaching is not as simple as other machining processes. Due to this complexity, introducing an applicable force model for all of the orthogonal and oblique broaching cutters can be problematic. In this paper, an attempt is made to present a new force model for broaching. The newly proposed force model expresses the cutting edge as a B-spline parametric curve and uses their flexibility to calculate the chip load as well as cutting forces for orthogonal and oblique broaching. Verified by experimental results, the presented model has a great capability to simulate broaching cutter geometry along with cutting forces and it can be applied for the entire broaching cutters. 1. Introduction Broaching is a powerful process for the production of complex internal and external profiles. As a machining process, it is commonly used for the machining of a broad range of profiles such as keyways, guide ways, holes and fir-tree slots on turbine discs. Broaching has considerable advantages in comparison to other machining processes. Roughing, semi finishing and finishing of a complex profiles can be done in one stroke of the machine which would require many passes in other conventional processes such as turning, milling, slot milling, etc. It can also produce parts with high surface quality and high geometrical and dimensional tolerances in one stroke. Since the number of simultaneously engaged cutting edges with the workpiece is higher than the other cutting tools, the chip load on each of them will be smaller and tool life is distinctively longer in comparison to other machining processes such as milling and turning [1]. It can be also mentioned that broaching machines are not as complicated as CNC milling or CNC turning machines and thus considered as a simple operation that requires not a highly skilled operator. In other commonly used machining processes such as milling and turning, final geometry of workpiece is generated by combination of tool and workpiece motion and there is no similarity between final geometry of workpiece and cutting tool geometry. In broaching, the geometry of machined part is derived directly by the inversion of broaching cutter geometry. Therefore unlike other machining processes, broaching cutters have a wide range of geometries as well as parts. Consequently, chip load has a complicated non-uniform 2D or 3D geometry depending on the profile complexity of workpiece. A unique feature of broaching operation is that it is not possible to change any of the cutting parameters during process but the cutting speed. That is because all other cutting parameters such as feed, depth of cut and width of cut are built in features of broac hing tool geometry which makes the tool design the most important aspect of broaching. Although broaching is well defined in industry, just a limited number of researches have reported work in the open literatures. In 1960 Monday [2] presents the most comprehensive source on broaching. A detailed description of broaching technology can be found in his book. Kokmeyer [3] edited collection of works on broaching representing the usefulness of the process. Gilormini et al. [4] analyzed the cutting forces on a single broaching and compared them to the forces in slotting and tapping process. Terry et al. [1] presented a system for optimal design of broaching tools. They presented the factors that affect productivity in broaching and explained the design constraints, their importance and how they are selected. Finite element was used to predict the tooth deflection and experimental data in order to create the general rules for designing. Sutherland et al. [5] presented a force model for broaching based on the oblique analysis to determine the forces in the gear broaching proc ess. Their model showed the relationship between contact area, chip load and cutting force. Sajeev et al. [6, 7] investigated the effects of broaching parameters on the tool and workpiece deflections and the final shape of the broached geometry. Budak [8] examined the performance of broaching tools used for broaching of waspaloy turbine discs with fir-tree profile based on the monitoring of force and power. It has been demonstrated that for most of the investigated tools, the load distribution among the broaching sections were non-uniform resulting in uneven wear. Recently Ozturk and Budak [9, 10] performed Finite Element Analysis to calculate the stresses in the broaching tool during the cutting process. The developed model is used to simulate the broaching process and predict the generated stresses in the tool to improve the tool design. He studied fir-tree profiles, simulated the broaching process forces and the tool stresses to improve the tool design. Later Kokturk and Budak [1 1, 12] performed an optimization on the geometry of the broaching tool cutting edges. In their study the cutting conditions are changed until they can satisfy the preset constraint. They also used the optimized conditions to improve the broaching process. Yussefian et al. [13] applied B-Spline parametric curves in modeling of boring process. Recently Hosseini and Kishawy [14] presented a general force model for orthogonal broaching using B-spline interpolation of cutting edge. By taking geometric flexibility of B-spline curves, their model was capable of modeling any arbitrary orthogonal broaching cutting edge geometry as well as computing the chip load for various cutting conditions. This paper proposes a 3D general force model for the broaching process. The proposed force model is capable of modelling of three force components using B-Spline interpolation of the cutting edge. Each cutting edge is first modeled by B-Spline parametric curves then the chip load is calculated by integ ration of area between two successive edges. The proposed force model for orthogonal and oblique broaching can calculate the chip load for any arbitrary geometry of cutting edge from the simplest to the most complicated. The proposed method is used to calculate the generated forces and the results are compared to the measured data. 2. Broaching tool geometry Broaching tool is a straight multi tooth cutter in which several cutting edges engage with the workpiece simultaneously and each tooth removes a portion of material from workpiece surface. Broaching cutter has a tapered flat or round profile with a series of teeth on its surface [4]. Each successive tooth in a broaching tool is higher than the preceding one to perform the cutting action and remove material from workpiece surface. Broaching cutters in their general form can be geometrically divided into three categories of teeth, namely, roughing, semi-finishing and finishing teeth. Roughing teeth remove the bulk of material from workpiece, semi finishing teeth produce the basic surface finish (surface quality), and finishing teeth provide the final surface finish and set geometrical and dimensional tolerances [4]. Figure (1) shows a typical broaching cutting tool. Figure 1: Schematic view of broaching tool Normally the maximum rise per tooth in broaching tool belongs to the roughing teeth which perform the major part of metal removal. The rate of rising per tooth slightly decreases in semi finishing teeth as they only remove a small portion of material from workpiece surface to improve the dimensional accuracy and surface quality. In the finishing part, all of the teeth have the same height. These teeth are not cutting teeth and they provide the desired surface quality and adjust the geometrical and dimensional tolerances in the predefined range. Figure (2) illustrates the general mechanism of cutting in broaching. Figure 2: Mechanism of cutting in broaching When broaching cutter is accurately designed, broaching process can be faster and more accurate than many other machining processes. Although the initial cost of establishing for a broaching process is comparatively higher than that of other cutting processes, the production cost is commonly low because of the high production rates and the long tool life. Figure (3) presents some of the important geometrical parameters of broaching cutting tool. Figure 3: Broaching tool geometry In figure (3), and are rake angle, clearance (relief) angle, tooth height and land length respectively. The rake angle and clearance angle can be selected based on workpiece material. The rake angle is usually selected between to and clearance angle is usually selected between to [12]. The total length of the tool and number of simultaneously engaged cutting edges can be determined by the pitch length which is a linear distance between two successive cutting edges. Based on some previously conducted research [10, 12, 15], it is concluded that it is preferable to have at least two cutting edges in cut to have a dynamically stable cutting. Another geometric feature of broaching tool is gullet space which is the empty space between two following teeth. The main advantage of gullet space is to retain the chip during cutting until the tooth leaves the workpiece. Once the broaching tool engages with the workpiece, chip is captured between tool and workpiece and it is maintained there until each tooth finishes the cut and leaves the workpiece. Small gullet space may cause tool breakage because of no space to keep the removed chip. It can also lead to poor surface finish due to rubbing of removed chip to the machined surface. If the gullet space is chosen too large it makes the tool very slender and decreases the tool strength and stability. According to the above mentioned reasons, it is very important to design the gullet space accurately to achieve acceptable space and dynamic stability simultaneously. In order to perform a reasonable design it is necessary to have a good understanding of cutting forces during machining p rocess. If the force model can predict the cutting force truthfully the result of force simulation can be used as an input for design and optimization process. 3. Mechanics of metal cutting in broaching Similar to almost all of the cutting processes, the cutting force in broaching can be expressed generally by three differential components which are directly related to chip load area and the contact length between cutting edge and workpiece such that [16]: (1) Figure (4) depicts the main features of oblique broaching and shows the force components generated during the chip removal process. Figure 4: Mechanics of oblique broaching In equations (1), is the differential component of tangential force, is the differential component of feed force and is the differential component of radial force. and are chip thickness and length of the cut for infinitesimal element along the cutting edge respectively. and are cutting and edge constants while the subscript refer to the tangential, feed and radial directions. Similar to the other cutting mechanics, the radial component of force appears only during oblique broaching when cutting edge has an inclination angle with the cutting direction. The total tangential, feed and radial component of cutting force for each edge can be calculated by integrating of those components along the cutting edge. Equation (2) shows the force integration along the cutting edge from the start to the end of engagement. (2) In equation (2), represents a differential element of chip area which is removed by the cutting edge. Equation (2) can be written in this format: (3) In the above equation, is chip load along the cutting edge and is length of engagement between cutting edge and workpiece. Figure (5) demonstrates the infinitesimal element of cutting edge, chip load and contact length for an arbitrary fir tree broaching tool. Figure 5: Infinitesimal element of cutting edge Since the chip load may vary along the broaching edge, it must be segmented into elements for which local thickness can be assumed constant. The geometry of chip along the broaching cutting edge is complicated however, since there is no relative motion between successive edges the chip load remains constant. The common approach for simulation of cutting forces is dividing the cutting edge to infinitesimal elements and calculating the area for each element separately. If total chip area can be calculated, cutting forces are obtained without the need for dividing the edge to elements. However, due to the variety and the complexity of cutting edge profiles in broaching, it is difficult to express the edge by an explicit function. Hence, calculation of the above integration in equation (3) is not a straight forward procedure. Representing the broaching cutting edge by B-Spline curves is a powerful way to express the geometry with parametric relations which makes integration and derivatio n along the edge much easier process. 4. Cutting edge interpolation by B-spline parametric curves A series of data point can be obtained by collecting the coordinates for each point along the cutting edge using inspection method such as CMM, digitizing or laser scanning. The desired B-Spline of degree p defined by control points passes through all those data points and expresses the cutting edge by a parametric curve. This parametric representation of the cutting edge can be easily appllied to perform derivation and integration along the edge to find the chip load area and the total engagement length. The interpolated B-spline cutting edge of degree p can be expressed as below [17-19]: (4) Where is interpolating B-Spline curve of degree p, is control points which control the geometry of curve and is B-spline Basis functions which can be computed by: (5) In equation (5), is a B-spline knot which belongs to the knot vector of . The equation (4) has unknown control points. For this reason, it is necessary to have a parameter like to relate the control points to the data points. Since parameter corresponds to data point , plugging into the above equation yields the following [19]: (6) There are n+1 B-spline basis functions and parameters in equation (6). Substituting t in to , these values can be organized in a matrix N as shown as below: (7) Data points and control points can be expressed in similar way: (8) And (9) In equation (9) matrix D is input data points which are represents the points along the cutting edge and matrix N can be obtained by evaluating B-spline basis functions at the given parameters [19]. D and N both are known and the only unknown parameter is matrix P. Equation (9) is a system of linear equations with unknown P, solving for P yields the control points and the desired B-spline interpolation curve becomes available. Figure (6) shows control points and desired interpolated broaching cutting edge using B-spline curves. Figure 6: B-spline interpolation of cutting edge 5. Calculation of chip load and contact length In orthogonal broaching, all of the cutting edges are parallel together and perpendicular to the cutter axis therefore the third column of matrixes and in equation (8) are zero and only two parameters of and in equation (4) is needed to represent the cutting edge. Figures (7a) and (7b) depicts a typical Cartesian coordinates in orthogonal and oblique broaching. (a) Orthogonal broaching (b) Oblique broaching Figure 7: Cartesian coordinates In contrast with orthogonal broaching in which all teeth are perpendicular to the cutter axis, in oblique broaching cutting edges have an oblique angle with cutter axis but they are still parallel to each other. In this case , , and all of the coordinates in the third column of matrixes and are non zero. B-spline interpolation of 3D curves is possible but little bit time consuming so it is preferable to transform the 3D to 2D and use the same method for 3D after transformation. Coordinates of point in Cartesian coordinates can be expressed by in plane as follows: (10) The above transformation can be done for all of cutting edge data points and in the new coordinate system matrixes is as follows: (11) Once matrix presented in new coordinate system the interpolation process can be done the same as previous method for 2D curves. As soon as the cutting edge is presented by B-Spline curves, chip area and cutting length for each cutting edge can be calculated directly from B-Spline equations as follows [13]: (12) Where indicate start of the cut, end of the cut, current cutting edge and previous cutting edge respectively. Equation (12) has two coordinate parameters and it is applicable for calculation of chip load and contact length for orthogonal and oblique broaching. 6. Cutting forces simulation In order to compare the presented geometric model with a real case, a broach cutter was selected and its cutting edges were modeled using B-Spline curves. The geometry of cutter was chosen based on previously presented research by Kokturk [12] to validate the newly proposed model capability. Figure (8) demonstrates the cutter geometry. Figure 8: Cutter geometry The geometrical features of cutting edge can be found in table (1) [12]. Table 1: Geometry of broaching cutter [12] In the next step, selected cutting edges were interpolated using proposed approach. Similar to other interpolation methods, B-Spline interpolation is sensitive to the number of data points. Increasing the number of data points yields a better accuracy but it makes the running time of the algorithm longer. Decreasing the number of data points, accelerate the algorithm but it has a negative effect on the accuracy. It has been shown that smooth parts of the curve are not very sensitive to the number of data points because inaccuracy occurs in the sharp corners where the curve direction changes suddenly. As a result, it would be better to use more data points at the sharp corners and less data point at the other parts to increase the accuracy and time efficiency of the algorithm simultaneously. Figures (9a) and (9b) show the B-Spline presentation of two successive cutting edges. (a) B-spline representation of the first cutting edge (b) B-spline representation of the second cutting edge Figure 9: B-spline representation of two successive cutting edges It can be seen from the above figures that B-Spline curve follows the data point at the sharp corner with high accuracy. 7. Results and discussion Figure (10) shows the final geometry of workpiece. Cutting conditions and force coefficients which are used in simulation can be found in table (2). Figure 10: Final workpiece geometry Table 2: Cutting conditions [12] 5 Since the cutting edge without oblique angle doesnà ¢Ã¢â€š ¬Ã¢â€ž ¢t have radial component of cutting force it was assumed that for this special case. The edge coefficients of cutting force are always very small in comparison to cutting coefficients so it has been assumed that , and are negligible. Figure 11: Simulated and experimental cutting forces for orthogonal broaching Figure 12: Simulated and experimental resultant force for orthogonal broaching Figure 13: Simulated and experimental cutting forces for oblique broaching Figure 14: Simulated and experimental resultant force for oblique broaching It can be seen from figures (11) to (14) that the results of newly proposed model are in good agreement with the previously published results [12]. Since there is no oblique angle in orthogonal broaching the cutting edge engaged with workpiece suddenly with full length so there is a jump in force diagram when each tooth engaged with workpiece. Due to presence of oblique angle in oblique broaching the tooth engaged with workpiece smoothly so the cutting forces rise gradually from zero to its final value. Also, in oblique broaching, fluctuation of cutting forces in the steady state part of the cutting is less than orthogonal one because when one of the teeth leaving the workpiece another one engages smoothly but the average force is higher because of longer contact length. 8. Conclusion In this paper, a force model is developed to simulate the cutting forces in orthogonal and oblique broaching using B-spline representation of the cutting edge. The new model can interpolate broaching tool cutting edge without any limitations which offer the simulation of cutting forces for any desired input geometry. In order to validate the new force model, the predicted cutting forces are compared to previously measured data [12]. The comparison showed a good agreement in both measured and predicted data for orthogonal and oblique broaching. The simulated cutting forces can be used to have a better understanding of process and optimize the geometric features of broaching cutter to achieve more efficient cutting which is under investigation of authors.

Adam Smith Wealth Nations Wealt Of Nations Summary Economics Essay

Adam Smith Wealth Nations Wealt Of Nations Summary Economics Essay In the first sentence of Wealth of Nations, Smith explained his conception of the nature of the wealth of nations. In so doing, he separated his views from those of the mercantilists and physiocrats. The annual labour of every nation is the fund which originally supplies it with all the necessaries and conveniences of life which it annually consumes, and which consists always either in the immediate produce of that labour, or in what is purchased with that produce from other nations. In a number of places throughout Wealth of Nations, Smith berated the mercantilists for their concern with the accumulation of bullion and identification of bullion with the wealth of a nation. Smith believed, in fact, that most mercantilists were confused on this issue. For him, wealth was an annual flow of goods and services, not an accumulated fund of precious metals. He also revealed an understanding of a link between exports and imports, perceiving that a fundamental role of exports is to pay for imports. Furthermore, in his opening sentence he implied that the end purpose of economic activity is consumption, a position he developed more fully later in the book. This further distinguishes his economics from that of the mercantilists, who regarded production as an end in itself. Finally, in emphasizing labor as the source of the wealth of a nation, he differed from the physiocrats, who stressed land. Smith went on to suggest that the wealth of nations be measured in per capita terms. Today when it is said, for example, that England is wealthier than China, it is understood that the comparison is based not on the total output or income of the two countries but on the per capita income of the population. In essence, Smiths view has been carried forward to the present. In the same paragraph in which Smith stated that consumption is the sole end and purpose of all production, he rebuked the.mercantilists because in their system the interest of the consumer is almost constantly sacrificed to that of the producer and because they made production, and not consumption . .. the ultimate end and object of all industry and commerce. So much for the nature of the wealth of nations. The rest of Smiths book is concerned with the causes of the wealth of nations, directly or indirectlyà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬sometimes very indirectly. Book I deals with value theory, the division of labor, and the distribution of income; Book II with capital as a cause of the wealth of nations. Book III studies the economic history of several nations in order to illustrate the theories presented earlier. Book IV is a history of economic thought and practice that examines mercantilism and physiocracy. Book V covers what today would be called public finance. Causes of the Wealth of Nations Smith held that the wealth of a nation, what we today call the income of a nation, depends upon (1) the productivity of labor and (2) the proportion of laborers who are usefully or productively employed. Because he assumed that the economy will automatically achieve full employment of its resources, he examined only those forces that determine the capacity of the nation to produce goods and services. Productivity of labor. What determines the productivity of the labor force? In Book I, Smith stated that the productivity of labor depends upon the division of labor. It is an observed fact that specialization and division of labor increase the productivity of labor. This had been recognized long before the publication of Wealth of Nations, but no writer emphasized the principle as Smith did. In our modern economyà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬even in the academic worldà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬division of labor is widely practiced, with notable influence on productivity. Smith illustrated the advantages of specialization and division of labor by borrowing from past literature an example that measured output per worker in a factory producing straight pins. When each worker performs every operation required to produce a pin, output per worker is very low; but if the production process is divided into a number of separate operations, with each worker specializing in one of these operations, a large incre ase in output per worker occurs. In Smiths example, when the process is divided into eighteen distinct operations, output per worker increases from twenty pins per day to forty-eight hundred. It is interesting that although Smith recognized the economic benefits of specialization and division of labor, he also perceived some serious social costs. One social disadvantage of the division of labor is that workers are given repetitious tasks that soon become monotonous. Human beings become machines tied to a production process and are dehumanized by the simple, repetitive, boring tasks they perform. But Smith had no doubt that human welfare is, on balance, increased by the division of labor. The division of labor, in turn, depends upon what Smith called the extent of the market and the accumulation of capital. The larger the market, the greater the volume that can be sold and the greater the opportunity for division of labor. A limited market, on the other hand, permits only limited division of labor. The division of labor is limited by the accumulation of capital because the production process is time-consuming: there is a time lag between the beginning of production and the final sale of the finished product. In a simple economy in which each household produces all of its own consumption needs and the division of labor is slight, very little capital is required to maintain (feed, clothe, house) the laborers during the production process. As the division of labor is increased, laborers no longer produce goods for their own consumption, and a stock of consumer goods must exist to maintain the laborers during the time-consuming production process. This stock of goods comes from saving and is, in this context, what Smith called capital. A major function of the capitalist is to provide the means for bridging the gap between the time when production begins and the time when the final product is sold. Thus, the extent to which production processes requiring division of labor may be used is limited by the amount of capital accumulation available. Smith therefore concluded: As the accumulation of stock must, in the nature of things, be previous to the division of labour, so labour can be more and more subdivided in proportion only as stock is previously more and more accumulated. Productive and unproductive labor. The accumulation of capital, according to Smith, also determines the ratio between the number of laborers who are productively employed and those who are not so employed. Smiths attempt to distinguish between productive and unproductive labor became confused and reflected normative or value judgments on his part. However, it manifests an awareness of the problem of economic growth. Labor employed in producing a vendible commodity is productive labor, Smith held, whereas labor employed in producing a service is unproductive. As an advocate of the changing social and economic order, he postulated that the activities of the capitalists, which resulted in an increased output of real goods, were beneficial to economic growth and development, whereas the expenditures of the landowners for servants and other intangible goods were wasteful. A man grows rich by employing a multitude of manufacturers: he grows poor by maintaining a multitude of menial servant s.10 According to Smith, what is true of the individual is true for the nation; thus, for the economy as a whole, the larger the share of the labor force involved in producing tangible real goods, the greater the wealth of the nation. Capital is required to support the productive labor force; therefore, the greater the capital accumulation, the larger the proportion of the total labor force involved in productive labor. Capitals are increased by parsimony, and diminished by prodigality and misconduct. This distinction between productive and unproductive labor also affected Smiths view of the role of the government in the economy. Just as the expenditures of the landowning class for servants and other forms of unproductive labor are detrimental to economic development, so is some part of government expenditures. The sovereign, for example, with all the officers both of justice and war who serve under him, the whole army and navy, are unproductive labourers.12 Smith insisted that the highest rates of economic growth would be achieved by distributing large incomes to the capitalists, who save and invest, and low incomes to the landlords, who spend for menial servants and who leave nothing behind them in return for their consumption.13 Furthermore, because economic growth is inhibited by government spending for unproductive labor, it is better to have less government and, consequently, lower taxes on the capitalists so that they may accumulate more capital.

Antipredator Defense as a Limited Resource : Unequal Predation Risk and

INSECTS WITH PARENTAL INSTINCTS More than two centuries ago, a Swedish scientist named Modeer described what appeared to be maternal behavior in the acanthosomatid shield bug Elasmucha grisea. He noted that the female did not fly away when an intruding object threatened her compact egg mass; instead, she remained steadfast and tilted her body towards the object (Tallamy). Unfortunately, this evidence, no matter how well documented, was not enough to convince countless people of the possibility of insects having parental instincts. The acknowledgement of parental behavior in insects was not a widely accepted idea for a number of years. Many people believed insects were too primitive to care for their young and that only when physical conditions became extremely severe were insects capable of expressing paternal abilities. The traditional view of maternal care is that it is an exceptional and relatively recent evolutionary leap forward (Tallamy). Fortunately, the assumptions made about maternal care in insects do not have to be accepted or rejected based only on faith or an educated guess; today it is possible for these predictions to be empirically tested so that the data may be recorded and analyzed. The following experiment is just one example of the various ways in which ideas regarding insects and maternal care may be effectively evaluated. Reginald B. Cocroft, of the Neurobiology and Behavior Department at Cornell University in Ithaca, New York, researched insects known as Umbonia crassicornis, or the thornbug treehopper. U. crassicornis offspring thrive in large aggregations on the often exposed stems of host-plants. These offspring are incredibly vulnerable, making them easy targets and subject to intense predatio... ...ymphs unequally. The mother distributed her protection equally throughout the entire aggregation along the length of the branch. Main Points: Location in relation to the mother is possibly competitive Location independent of the mother is possibly competitive, but only exploitation competition Signaling is not competitive for maternal care, it is cooperative and the mother distributes protection along the aggregation equally.

The magazine's editors chose the nameless soldier to represent the 1.4 million men and women who make up the U.S. military, which led the invasion of Iraq nine months ago and a week ago captured deposed leader Saddam Hussein. About 130,000 U.S. soldiers remain in Iraq, with others deployed in Afghanistan, South Korea and elsewhere. Soldiers were singled out as the top newsmakers of the year because "the very messy aftermath of the war made it clear that the mission had changed, that the mission had not been completed and that this would be a story that would be with us for months, if not years, to come," Time Managing Editor Jim Kelly said. The selection echoes 1950, the year the Korean War began, when editors picked the American GI for the cover, writing that "it was not a role the American had sought, either as an individual or as a nation. The U.S. fighting-man was not civilization's crusader, but destiny's draftee." The 2003 Person of the Year package, which hits newsstands Monday, focuses on a 12-person artillery survey unit stationed in Iraq to tell the story of the American soldier. Two Time journalists embedded with the platoon were injured in a grenade attack this month. Three soldiers with the unit -- Marquette Whiteside, Billie Grimes and Ronald Buxton -- are shown on the cover. The magazine glorifies soldiers but not the Bush administration for putting them in Iraq, calling troops "the bright sharp instrument of a blunt policy," and leaving it to scholars to debate "whether the Bush doctrine is the most muscular expression of national interest in a half-century." The justification for a U.S. military presence in Iraq has been widely questioned, as coalition forces have found no weapons of mass destruction, which President Bush had argued Saddam was stockpiling. Guerrilla attacks against U.S. and allied forces stationed there have escalated over the months since May 1 when the president declared an end to major combat. More coalition troops died in November than in any other month: 104, including 79 Americans. "A force intensively trained for its mission finds itself improvising at every turn, required to exercise exquisite judgment in extreme circumstances," the magazine said. "They complain less about the danger than the uncertainty -- they are told they're going home in two weeks, and then two months later they have not moved." The Pentagon has said it expects to reduce the number of American troops in Iraq to just over 100,000 by May.

Emma and Clueless Speech

Through close analysis of the novel Emma, by Jane Austen and the film Clueless by Amy Heckerling, we discover that both texts are influenced by, and reflect the values of their respective contexts. Emma is set in the isolated, rural town of Highbury, England in the early 1800’s, at a time where society had placed value on social hierarchy. This distinction between classes was largely determined by family lines and inheritance. It is in the upper class of society that Jane Austen places her protagonist, Emma, â€Å"handsome, clever and rich†¦with very little to distress or vex her†. Emma’s desirable situation had led her to possess a self indulgent attitude towards life, as Austen intends her audience to identify with the cynical remark that she has â€Å"the power of having rather too much her own way†. However, Austen contradicts this third voice by the dialogue which establishes Emma to be a character of good intentions â€Å"No papa, nobody thought of you walking†. This contrast between third person and dialogue creates a discrepancy between Emma’s thoughts and Austen’s intrusive moralistic views. From the irony present here, satire is created, encouraging the reader to reflect on Emma’s behaviour as a reflection of the context of her society and the value put on social hierarchy and status. The opening scene of Amy Heckerling's film, Clueless, made in the 1990’s, immediately adopts Austen's ironic tone. The energetic montage and quick succession of camera angles of Cher and her fellow teenagers indulging in luxurious activities in Beverly Hills USA, establishes the materialistic world in which the movie is set. Heckerling appeals to her audience by creating such strong imagery, however she contradicts these perceptions by juxtaposing everything her audience views. The blaring song â€Å"We’re the kids in America† provides ironic commentary in that it is strikingly evident that these wealthy teenagers are the complete opposite from the average ‘kids in America’ as they have the ability to embrace all aspects of consumer ideals. Through this Heckerling establishes Cher as being an imitation of Emma â€Å"having too much her own way†. The contrast between Cher’s first voiceover â€Å"I actually have a way normal life for a teenage girl† whilst she picks out her designer outfit on a computer allows Heckerling to provide an authorial voice, much like Austen, where she critiques teenage self absorption and the society that cultivates this trait. Both texts primarily focus on the social values of marriage, romance and sex. During Austen’s time, marriage was concerned as a way of preserving your social rank and financial status and often these values took primacy over romance. This is evident when Emma speaks that Mr Elton would give Harriet â€Å"everything she wanted- consideration, independence, a proper home†. Austen challenges societies values by making Emma oppose these views and have â€Å"very little intention of marrying at all†. However, Austen allows Emma to succumb to society’s expectations with her marriage to Mr. Knightely. This reaffirms the reality of Austen’s society, she allows her audience to see her view but highlights that she cannot change this value. Heckerling chooses to replace the importance of marriage, with the importance of sex to suite the context of contemporary society. Sex before marriage is a prevalent issue in the film and is highlighted as common amongst most social classes. Tai’s comment to Cher â€Å"Why am I even listening to you- you’re a virgin who can’t drive† reflects societies consideration as to what is important. Like Emma, Cher rejects her social expectations and admits to remaining a virgin. However, Heckerling sets up a paradox around Cher, exaggerating a materialistic and sexual blonde who ironically remains a virgin despite this image. Although the importance of sex takes focus in the film, Heckerling chooses to end Clueless with a marriage, highlighting that it is still a value in modern society. Both Austen and Heckerling challenge their audience to confront their own presumptions concerning their society’s values. Moral education is a value personified through significant figures in both protagonist’s lives. In Emma, Mr Knightely is the catalyst for Emma’s moral education and growth. One of the significant turning points for Emma’s transformation is the Box Hill incident where Emma cruelly insults Miss Bates. Jane Austen use’s Mr Knightely to enter her novel to criticise Emma’s behaviour â€Å"Better be without sense, than misapply it as you do. † In Clueless, it is Josh who sparks Cher to â€Å"make-over her soul†. It is the incident when Cher insults Lucy saying she is a Mexican and Josh insults her saying â€Å"your such a brat† that is the vehicle for Cher’s moral education and ultimately making her a better person. Through these men, both Austen and Heckerling are able to criticise not only Emma and Cher, but the moral values society shape as acceptable. Through exploring both texts, it becomes increasingly evident that both authors have attempted to reflect their societies. Through their protagonists, they challenge societies standards and expectations and appeal to their audience to overcome these barriers. Therefore we come to the point that while human nature does not change, the context and values do.

Existentialism vs. Phenomenology Essay

Existentialism vs. Phenomenology and the response to Hegelian Idealism Absolute idealism was a huge part of Western culture but through the nineteenth and twentieth centuries the greatest political movement took place. Marxism was this great political movement. The movement had an affect on theology and art. Jean-Paul Sartre, a continental philosopher who lived in the nineteenth century was an existentialist. Some of the main themes of extentialism are: †¢ Traditional and academic philosophy is sterile and remote from the concerns of real life. †¢ Philosophy must focus on the individual in her or his confrontation with the world. †¢ The world is irrational (or, in any event, beyond total comprehending or accurate conceptualizing through philosophy). †¢ The world is absurd, in the sense that no ultimate explanation can be given for why it is the way it is. †¢ Senselessness, emptiness, triviality, separation, and inability to communicate pervade human existence, giving birth to anxiety, dread, self-doubt, and despair. †¢ The individual confronts, as the most important fact of human existence, the necessity to choose how he or she is to live within this absurd and irrational world. (Moore-Bruder, 2005) The extentialist believed that there was no answer to the existential predicament. They say life can only deteriorate and without struggling through life a person can find no meaning or value to the life they lead. Some of these themes had already been introduce before Jean-Paul Sartre came up the additions. The philosophers, Arthur Schopenhauer, Soren Kierkegaard, and Friedrich Nietzsche were the contributors to these themes. All three had a strong distaste for the optimistic idealism of Georg Wilhelm Friedrich Hegel and for metaphysical systems in general. Such philosophy, they thought, ignored the human predicament. For all three the universe, including its human inhabitants, is seldom rational, and philosophical systems that seek to make everything seem rational are just futile attempts to overcome pessimism and despair. Soren Keirkegaard’s fundamental question in life was is there anything in this world or outside it to which the individual can cling to keep from being swept away by the dark tides of despair? He was as almost entirely concerned with how and what the individual actually chooses in the face of doubt and uncertainty. He thought the only way to be grated relief from despair was to have a total commitment to God. Friedrich Nietzsche was convinced that the world was run by a cosmic force and that it is driven by will to power or will power. This way of thinking was quite different from Keirkegarrd. Nietsche believed you had to control your own destiny and seize what was yours. He led a more exciting life, a more passionate one. Keirkegaard was very depressed and spent most of his life battling despair but found comfort in God. Nietzsche used to say â€Å"Which is it, is man one of God’s blunders or is God one of man’s? † While both of these men had different views from each other they agreed to disagree with extentialism. Existentialism as a philosophical movement was something of a direct reaction to perceived social ills and was embraced by artists and writers as much as by philosophers So it is not surprising that two of the greatest existentialist philosophers, Albert Camus and Jean-Paul Sartre, wrote drama, novels, and political tracts as well as philosophical works. Phenomenology interests itself in the essential structures found within the stream of conscious experience—the stream of phenomena—as these structures manifest themselves independently of the assumptions and presuppositions of science. (Moore-Bruder, 2005) Phenomenology, much more than existentialism, has been a product of philosophers rather than of artists and writers. But like existentialism, phenomenology has had enormous impact outside philosophical circles. It has been especially influential in theology, the social and political sciences, and psychology and psychoanalysis. Phenomena is the distinction between the way something is immediately experienced and the way it â€Å"is. † Both Hegel and Kant were philosophers of Phenomenology. Also, Edmund Husserl and Martin Heidegger were phenomenologists. Husserl introduced transcendental phenomenology, whose purpose it was to investigate phenomena To investigate phenomena in this way is to â€Å"bracket† or â€Å"exclude† one’s presupposition about the existence or nature of an â€Å"external† or â€Å"physical† or â€Å"objective† world. Husserl called this process phenomenological reduction without making any assumptions about the world. Heidegger, too, was convinced that it was necessary to look at things with fresh eyes, unshrouded by the presuppositions of the present and past. According to Heidegger, we are basically ignorant about the thing that matters most: the true nature of Being. It is usually with reference to his earlier work that Heidegger is sometimes called an existentialist. Heidegger himself resisted this appellation. Yet he was very much influenced by Kierkegaard and Nietzsche, and the concern expressed in his early works with such existentialist themes as fear, dread, meaninglessness, and death is quite evident. Sartre studied in Germany for a brief time in the 1930s and was influenced by Heidegger. Sartre attributed the concept of abandonment to Heidegger, and Sartre and Heidegger both were concerned with the concepts of bad faith, authenticity, a life’s project, and others. In philosophy it is true that each view even if they are opposing influence one another. In the last third of the twentieth century, diverse Continental voices were raised against what they saw as suspicious assumptions about the meaning of right and wrong, the nature of language, and the very possibility of human self-understanding. Some Continental philosophers have been suspicious about Western metaphysical systems that they claim lead to the manipulation of nature or that set up a certain ethnic or cultural perspective as absolute truth. As the years go by new philosophers try to prove the others wrong and so is the development of philosophy always on going. Reference Moore-Bruder. 2005.

Paranormal Existences

Paranormal Existence Is someone or something else among us at this moment, in this room, something we can’t even see? Have you ever wondered what else is really out there? Unexplained happenings occur every day. Spirits or ghosts are thought of just being people that have passed away but there has to be more to it. Paranormal activity is defined as experiences that lie outside the range of normal experience or scientific explanation.At some point in everyone’s life they will experience some kind of unexplained activity. Many people ask the question if it actually exists or if it’s all in their head. Scientists often say that these so called â€Å"spirits† do not exist. Only personal experiences can interpret your own feelings about paranormal existences. My story is about a spirit that lived on past their death. One night a couple months ago me and my friends were playing on her wigi board. Her dad had died 5 years earlier due to a horrific car crash.Her f amily had always seen balls roll across the room and other strange things happen without explanation; they always assumed it was him. When we started playing around with the board the first letter of the girl’s dads name showed up and her eyes instantly filled up with tears, like a helpless child left all alone, the second letter was the second letter to his name, the same with the third. By this time my friend was balling, she of course knew it was her father. We continued playing until the last letter of his name showed up.At this moment we heard a vase upstairs shatter into a million pieces, just like the car windshield had done when his helpless body had gone through it, instantly killed. We ran upstairs to find the vase and its contents of flowers spread all over the floor. Then we replaced it with a new vase and reassembled the flowers to how they were. The next morning her mother walked downstairs with a flower in her hand and asked, â€Å"Why did you put a flower nex t to my bed? † That night changed the way I thought about spirits forever.I never thought anything like that could ever happen to me. Anyone who experienced that kind of activity and the intensity in that room could easily say they felt a presence surrounding them. In the moment of that glass shattering was the one of the scariest moments of my life. I will always remember the terror racing through me, my heart pounding, sounding of horse’s strong hooves beating against the track, like thunder rolling in and the suspense leading up to the storm.Saying spirits like this don’t exist is outrageous considering how many people actually experience real activity. Some people don’t want to believe this is real simply because they are scared of it. Many others find it very interesting to study about and explore the possibilities of what else could potentially be out there with us in our everyday lives and something you aren’t even able to see. Everyone has d ifferent views on if paranormal existences are actually real. Mysterious things could happen at any time, and when they do, be prepared.

Explore the impact of social, cultural and historical on your play

The historical, social and cultural influenced our play immensely because in order to create an understanding of our stimulus gender we needed to explore different sides to gender. We decided that in order for the audience to work out the meaning behind our play they needed to fully understand the idea of gender both past and present. During the creation of our play we thought it was important to bring up certain topical issues, we decided the main issues would be how women were treated in the past and present, domestic violence, love and relationships, stereotypes and social roles. We chose the idea of ‘lion tamers' because it was based on a circus however we twisted it so the scene was ‘lady tamers' to show how women were treated in the past. We started off with the ladies as wild animals with the men in the middle shouting out the orders such as ‘wash the floor'. Then we went onto more advanced techniques were we stood in a ‘Stepford wife pose' and spoke lines such as ‘have dinner ready, plan even the night before so he can have a warm meal on time. In order to create a realistic impression of what women's roles were in the past we looked at The Good housewife's guide this was a booklet of instruction from the 50s telling young women how to be a good housewife and because some of the instruction were incredibly †¦Ã¢â‚¬ ¦ and unrealistic which we thought the audience would find humorous. We then decided to do go the other extreme with the scene where the ladies take over, we wanted the women to be powerful both mentally and physical this was to show how times have changed and in particular how women in society have changed. A very important issue we wanted to concentrate on was domestic violence because this was a hard hitting issue involving gender. We researched different aspects of domestic violence and found that it is equally common nowadays as it was in the past and although it isn't necessarily true for every case men seem to be the†¦Ã¢â‚¬ ¦ of the problem. We had a real problem incorporating this issue into the initial idea of the circus because we didn't know how to make a serious topic humorous. Eventually we came up with a Punch and Judy sketch and this was Perfect because it showed the issue of domestic violence and stuck to the idea of the circus. As a group we decided that it would be nice to look at the positive side of gender because up till then it had all been negative. We used the idea of a tight rope act to show the ups n downs of relationships and love, we had a boy at one end of the tight rope and a girl at the other and they would walk along and take turns saying what they didn't like about each other and the other person would begin to wobble on the tight rope however after each little speech they would end it with ‘but I love him/her. ‘ We wanted to embrace the opposite sexes differences and make the audience view gender in a positive light.

Summary the artical Essay Example | Topics and Well Written Essays - 500 words

Summary the artical - Essay Example Blue oceans consist of all those industries that create new demand and market or expand the boundaries of the existing demand and market. By doing so, they generate new opportunities for profit and growth. Blue oceans have been a source of growth in the past and will remain so in the future. Emergence of new industries and wide products differentiation in the existing ones in the past demonstrate this phenomenon. As globalization spreads and barriers fall further, red oceans will increasingly become competitive with more products standardized resulting in price wars and reduced profitability. Only blue oceans will ensure growth and profit in the future. However, paradoxically, there is a bias in favor of red oceans. A study found that, out of 108 new ventures, 86 percent pursued red oceans strategy contributing to 62 percent of revenue and 39 percent of profit. Only the remaining 14 percent new ventures followed blue ocean strategy but they contributed 38 percent of revenue and 61 percent of total profit. Blue oceans have four defining features, as identified based on the data of 100 years in auto, computer, and movie and theater sectors. First, firms might create blue oceans through technological innovation in some cases but they tweak the existing technology to new uses in most cases. Second, existing firms often create blue oceans within their core competency areas rather than stepping out to new frontiers. Third, the most appropriate unit of analysis is not a firm or industry but the strategic move involving managerial actions and decisions to tap the blue oceans of demand and market. Fourth, creation of blue oceans builds new brands. Strategic orientation is more important than large R & D budget to create new market space. Red ocean strategy and blue ocean strategy have their own characteristics. In red ocean strategy, firms compete in the existing market space, beat the competition, exploit the existing demand, make a trade-off

K-129 Submarine explosion Essay Example | Topics and Well Written Essays - 750 words

K-129 Submarine explosion - Essay Example The intelligence and the senior executives of each country do not have trust on the military to settle the issue. For that reason, the issue of the Nuclear Missile Submarine is still shrouded in mystery and uncertainty on what transpired. Different theories to explain why the submarine sank no American or Russian fail to state that the explosion result from an attempted nuclear missile launch as the primary source of the submarine demise. For many years, there is a speculation that an exploding warhead leads to the catastrophe. In the 1960s, small groups of American and Russian military specialists secretly cooperate to prevent a likely nuclear war. Wagner believes that Americans drowned their submarine in 1968. The Soviets had a direct line into the United States Navy Atlantic Fleet submarine headquarters. In the early 50s, American navy began installing hydrophone cables on the ocean floor. The underwater microphones could pick up sounds transmitted back to shore and converted to visual display. The author finds that the low frequency sounds travel in great distances to pick up noise from underwater explosions. Military specialists identified the sounds and determined if the sub was a diesel or nuclear powered and where it likely belonged. The development of the technology helped the specialists to establish the territory of the K-129 as well as other subs. Sewell finds that an expert witness testifying on the occurrence cited that it was an explosion. United States knows the whereabouts of the submarine since they recorded the wreck and buried the military officers at sea. . United States classifies all the information concerning the wreck as secret. The court investigating the sinking proves that sounds picked from hydrophones compare to those of the sinking submarine. Several SOSUS arrays recorded sufficient triangulation to provide a locus on the possible wreck site. Soviets naval lack an equivalent of

Essay Example The risks and benefits, the rights and wrongs, or the pros and cons of genetically modified food and science are global concerns in both public and private arenas (Adolphs, Hamilton and Nerlich, 58). In today’s technological world however, GM crops and products play an important role in driving modernization and as such they are here to stay; as long as focus is not placed on future technological advancement instead of today’s risks and disadvantages, and if research, assessment, controls and policies are adequately and stringently evidenced then the benefits, will eventually negate the risks. Martin Teitel, in his article entitled ‘Unsafe at any Seed?’ argues against GM food claiming the argument that GM foods are better for the environment, farmers and consumers â€Å"should be taken with a grain of salt† (1). He further purports that this new technology has grown too quickly with insufficient testing, has entered supermarket shelves too soon, and necessitates further research and an objective commission to verify and validate the safety of such foods prior to entering the market. This paper will argue in agreement of Teitel’s paper in some respects but will not concur with others. Although Teitel has put forward some pertinent points that are significant if biotechnology is to continue and develop, his argument falls short in that he fails to consider the debate from two perspectives – that of the opponent and that of the advocate of GM foods – and has remained steadfast on the side of opponents at the risk of sounding dogmatic and ill informed. The situation is not as black and white as Teitel paints it; within the developed world scientists are at odds in their convictions on measurement of risk, both for health and the environment. Many are convinced that assessments are not necessary or are too harsh, while

Center for Medicare & Medicaid Services Term Paper

Center for Medicare & Medicaid Services - Term Paper Example Center for Medicare & Medicaid Services The people that need these services are directly affected when the health sector is not up to their task (Thorpe and Cascio, 2013). Therefore, it is in the best interests of the health care sector to guarantee it has contained all its challenges and setbacks in ensuring the public is getting the much needed services without delay. The stagnating problem in the health care sector is provision of high quality services that are affordable by all the people in the region. According to the recent statistics, many people find it hard to afford the health care services and in most cases, they have to struggle in acquiring such services (Elliott, 2012). They have constrained budgets and have to minimize these budgets to continue living. As such, some people find it a prudent idea to forego healthcare services as they find these resources useful in other needy situations. This is a repulsive problem in many populations that find health care services expensive (Shortell, Casalino and Fisher, 2010). Similarly, there is a stagnating problem when governing bodies try to improve the quality of health care and delivery of these services. The health care is marred with costs that are increasing with every move they take to improve the delivery of health care services (Rogers, 2006). As such, the healthcare sector is in a biza rre situation where it is trying to reduce costs in delivering affordable health care, but on the other hand, the costs keep bulging due to the need to improve the service delivery. (CMS Innovation Center, 2012). How Addressed by ACA The ACA created the centre for Medicare and Medicaid innovation to deal with the issue. The institution is crafted for the ostensible reason of perfecting health care delivery and focusing on the payment systems (The Center for Medicare and Medicaid, 2012). Similarly, the institution is mandated to support care coordination in the health care sector and enhancing professional practice in healthcare. This institution was instated to deal with the menace of high spending in the health care sector while dealing with provision of high quality services. There are various approaches that are used by the CMS (Sharamotaro, 2011). First, it was to test the delivery and payment models in the institutions which would be used to measure the improvement in service d elivery. Secondly, the institutions considered relaxing some laws that were governing relationships in the financial sector especially directed towards the providers (Cosgrove, 2012). Thirdly, there was waiving of some acts in order to enhance testing. Some of the acts that were affected include the social security act. Pros and Cons There is both positivity and negativity in the approach taken by the institution. To begin with, there is positivity in that many people will have access to affordable medical care. The people that need these services will only spend part of their income in acquiring high quality healthcare services (Centers for Medicare & Medicaid Services, 2012). Secondly, there is positivity in that people will have access to high quality services that are provided in the institution (Baron, 2012). Many institutions will step up
