Max Weber Essay

Maximilian Carl Emil Weber or better known as Max Weber is a German political economist and sociologist who is considered as one of the great founders of the contemporary discipline of sociology and public administration (â€Å"Weber, Max,† n. d. ). In a brief background, Max Weber started his career in a learning institution named University of Berlin (â€Å"Weber, Max,† n. d. ). Afterwards, he also worked in several Universities such as Heidelberg, Munich, and Freiburg as an academician in education (â€Å"Weber, Max,† n. d. ). Moreover, Max Weber is also famous in his thoughts about politics and religious faith as most of his literary works deal with rendering profound explanation in sociology of religion and government (â€Å"Weber, Max,† n. d. ). His essay called The Protestant Ethic and the Spirit of Capitalism is considered to be the main manifestation of Max Weber’s standpoint about religion, which is later commended as the start of his excellence in the said topic (â€Å"Weber, Max,† n. d. ). Politics As A Vocation, on the other hand, is a lecture of Max Weber about government that has been well essential in the study of contemporary Western political science (â€Å"Politics as a Vocation,† n. d. ). Likewise, Max Weber also provides his own profound definition of Power, Authority and Coercion, just like any other sociologists. Thus, Max Weber defines power as the possibility that an individual or a person within a social relationship would be in a position to implement his or her own will despite the opposition, regardless of which grounds such probability rests (â€Å"Max Weber’s definition of the modern state 1918,† n. d. ). In addition to this, Max Weber states that power could either be legitimate and illegitimate. Authority, on the other hand, is characterized by Max Weber as the actual exercise of power that is directly set under the legal grounds. As such, he said that authority is the practice of legitimate power. In the end, Max Weber rationalization about coercion is the utilization of force under the grounds of illegitimate power (Kirby et al. , 2000). Nonetheless, Max Weber as a reputable sociologist had done a clear distinction on power, authority and coercion that has been significant in the sociology of religion and government.

“What is right and wrong?” and “What is Truth?”

Life is characterized by many situations that require decision making, especially on moral grounds. The issue of what makes an action right and wrong has been studied for a lengthy period of time and several theories developed to address this issue. Socrates and Aristotle are some of the early philosophers who came up with theories about the rightness or wrongness of actions. As noted by Warnek (2005), Socrates considered self-knowledge as necessity of life and also, an important ingredient to success. Socrates stated that every individual needs to attain self-knowledge which is acquired by studying every fact necessary for existence. Socrates believed that by possessing knowledge about what is right, individuals are most likely to perform good deeds and that the bad deeds in the society come from those who are ignorant of what is right and wrong. Socrates proposed that, by being aware of the spiritual and mental consequences of wrong actions, no individual would even consider engaging in such actions. According to Socrates, any individual who is aware of a truly right action will automatically choose it over the wrong one. Aristotle on the other hand stated that all humans have physical, emotional and rational natures. Of the three, Aristotle considered the rational nature as not only being the most important of the three but also uniquely human and fundamental to philosophical self-awareness. Aristotle encouraged moderation and regarded extreme actions as being immoral and degrading. For instance, recklessness and cowardice are extreme virtues of courage. Therefore, According to Aristotle, humans should strive to live well by letting their actions be governed by moderate virtues. He further stated that this way of life can be achieved by choosing the right things in life at the right time and place. The ethical theories associated with the modern era include consequentialism and deontology. Consequentialism is made up of moral theories that propose that the rightness or wrongness of an action is determined by the outcome or the consequences of the act (Darwall, 2003). Thus, from the perspective of a consequentialist, a morally right act is one that results in a positive or good outcome. Consequentialist theories put a lot of weight on outcomes when assessing the rightness or wrongness of actions. Generally, according to consequentialists, consequences always outweigh all other considerations when determining right and wrong. Most of the consequentialist theories generally address issues like consequences considered as good, the main beneficiaries of moral actions, the mode or judging consequences, and who is to judge them. Consequentialism can be categorized according to the consequences that matter most. For example, hedonistic utilitarianists propose that good or the right actions are those that result in increments of pleasure, and the best actions are those that result in the most pleasure. The other category is that of eudaimonic consequentialism, who believe that the right action is one that ultimately aims at making an individual achieve a flourishing and full life (Darwall, 2003). Similarly, the consequence that matters most to aesthetic consequentialists is beauty and there are numerous other consequentialist theories that regard different things to be of uttermost importance. Deontologists differ from consequentialists in that, unlike consequentialists who examine the consequences when seeking to determine the rights and wrongs, deontologists examine the virtue of the act. Thus, according to deontologists, an act can be right even if it results in negative or bad consequences. Immanuel Kant is among the individuals who adopted the deontology when coming up with theories addressing righteousness and wrongness (Brooks & Dunn, 2009). Kant argues that individuals must act according to their duties if their actions are to be considered right and also that it is the motives of the individual carrying out the act that are the primary determinants of the rightness or wrongness of their actions. Postmodern ethics however approaches this issue from a different perspective. According to postmodernists, the world is full of rationality and if one is to determine the rightness or wrongness of an action, the individual would first have to study the complex situations surrounding the action. Thus, according to postmodernism, an idea cannot be simply regarded as right or wrong and there are no moral absolutes. For instance, if one were to find oneself in the Second World War, hiding a Jew in his or her house and a Nazi solder knocks on the individual’s door and asks the individual if he or she has any Jews in his or her house, would it be right or wrong to tell the truth knowing that his or her answer will determine if the Jew lives or not? Such an issue presents a complex moral dilemma given that it is wrong to tell a lie about the Jew being in the house but at the ame time, it is still wrong to let an innocent individual be killed when it can be prevented. For a long time now, individuals have utilized dilemmas like the one stated above to argue that there are no moral absolutes. The above situation is an example that one can use to argue that lying is not always wrong and that in such complex dilemmas, the right thing to do is determined by the act that results in a greater good. Most individuals in the world today embrace reality and argue that ethics is relative to individuals, time and the culture of the individuals. It is with such arguments that the world today is presented with numerous disagreements about issues like abortion, the death sentence, pre-marital sex and gay rights, to mention but a few. Most individuals have different views when it comes to interpreting the rightness or wrongness of some controversial issues such as the above mentioned. What is truth? The definition of truth may be simple but its interpretation is complex and just like the question of what is right and wrong, varies from individual to individual. A basic definition of truth is that it is that which is agrees with reality, actuality or simply, a fact (Rappaport, 1999). One way to approach the definition of truth is by considering that all the perspectives of approaching truth are equally valid and that truth is relative to an individual. This perspective that bases truth on realism is however faulty given the contradictions surrounding relativity. For instance, what is true to one person is not always true to another as shown by the contradiction between religious truths. Christians believe that Jesus is the son of God and the Messiah; a view Muslims do not agree with. This is not to imply that there are no absolute truths. An example of a sentence of absolutely truth is that, ‘something cannot create itself. ’ Logically, the thing would first have to be present if it is to possess the ability to create and if it already exists, then how would it create itself? The above example is truth based on logic but there are truths that cannot be logically explained for instance, stating that an individual truly loves another. It can be very difficult to use the theories of logic to explain the individual’s feelings. From the above examples, it can be concluded that truth is that which obeys the rules of logic and reality, or any of the two. Realism, to a certain degree agrees with logic and truth and therefore presents the best approach towards the determination of truth. To adopt a relative perspective however, individuals must be ready to acknowledge that a statement regarded as being true by one individual may not be acceptable by another.

Communication with Families Essay Example | Topics and Well Written Essays - 750 words

Communication with Families - Essay Example Teachers should treat everyone equally. A very good thing that is visible from the address that the teacher has made a generous consideration when she is making the speech. She even had a translator at the speech; this would have reduced the barrier between the parents and the teachers. It is very important that the barriers are reduced so that the communication takes place in a perfect way. Another consideration that she has made is that she has kept the meeting after 8 pm. This makes the parents feel that the teacher is actually looking forward to the improvement of the children and they are genuinely concerned. The parents would feel honored and respected and would actually take interest in the child’s growth and development. For a proper communication it is very important that all kinds of barriers are crossed and gotten rid of so that the message goes without any impurity to the receiver. That is why the explanation of the jargons and the terms is important and it has bee n done by the teacher who is giving the introductory session. Also, she is doing it subtly and, therefore, the parents would not feel degraded or troubled when they feel that the teacher is explaining each and everything (Mendoza, 2003). ... The teacher has also made it easier for the parents to become involved as she has used simpler terms and jargons so that the parents can feel that they are not very laid back or not educated at all (Mendoza, 2003). This quote is from the part when the teacher actually makes the effort to disclose all the information to the parents and plans on making this easier for them. According to Welch and Tisdale, â€Å"To make sure you understand how my classroom will be run, I have written a disclosure document and made a copy for all of you. A disclosure document is just a written explanation about how I will grade your children, what my class rules are, and other general information to help you understand my classroom† (Welch &Tisdale,1986). Another quote that can be given here is the one that is related to the extra time that teacher is willing to put in and has kept it at the time when the parents of the children are available (Epstein, 2001). The quotes clearly show that the teach er is making efforts to actually help the parents in continuing the education of their children and providing them guidance at each and every step so that the parents can actually participate equally in the education of the children. It is very important that despite being sensitive about the feeling of the parents the teacher should have also provided some kind of help and guidance so that the parents who are disabled or have disabled children should also be provided due guidance. The documents should also be written in easier and the normally used language so that the parents do not have any kind of issues in actually understanding the matter in it. Failure to understand the document can lead to non compliance (Epstein,

Dialect and Venacular Term Paper Example | Topics and Well Written Essays - 1000 words

Dialect and Venacular - Term Paper Example It cannot be denied that dialect influences phonological awareness. Divergent speakers end up bypassing certain phonemes. In a study conducted by Rebecca Treiman (2004) it was established that due to this bypass, divergent speakers were more likely to spell words wrong. The study tries to find the truth in the statement whereby some phonological experts opine that spelling and reading development is affected mostly by phonology. It is how people speak that they read and/or write. The result of Treiman’s study (2004), which involved African Americans, who spoke African American Vernacular English (AAVE) as well as SAE speakers, both as participants and experimenters, showed that AAVE speakers were more likely to spell words based on how they spoke them, whereas SAE speakers made spelling errors when the experimenter calling out the words to be spelled was an AAVE speaker. Treiman (2004) attributes this as one of the contributing factors to the lag seen in the literacy skills of African Americans. Interestingly enough, there is a positive influence of dialect on phonological awareness as well. People used to, or growing up with, vernacular differing from SAE are actually more phonologically aware than those who only use SAE. Those speaking dialects are often in minority and have to learn the â€Å"standard† way of speech as well, or at least be able to understand it orally. For this reason, divergent speakers often have fine-tuned phonological awareness, as they are much more conscious of the differences of phonetics between their own vernacular and the standard speech. This hypothesis was also put forward by Sligh and Conners’ 2003 study, in which they stated that it could be possible that divergent speakers developed â€Å"good phonological processing skills, due to their experience with two dialects in which there are phonological differences† (p. 222). There needs to be more research done with this regard, however. It is often take n to be a fact that vernacular and speech have a direct relationship with reading skills. Children who come from a background where Standard American English (or SAE, as Sligh and Conners term it in their 2003 study) is not used, instead being replaced by a dialect, are often expected to give low results with regard to their reading skills. It is thought that as their vernacular does not allow them to use SAE, they will not be able to learn to read it either. Perhaps this has got more to do with prejudice than reality. As Goodman and Buck opine (1997), often teachers confuse language difference with language deficiency, thus undermining the divergent speakers’ ability to learn to read normally, like those other than him, as well as hampering their self-confidence. There is a â€Å"linguistic discrimination† (Goodman & Buck, 1997, p. 455), which can be, and often is, the cause of low reading skills and reading impairment in divergent speakers. This attitude often is res ponsible for a vicious cycle in which the teacher, unintentionally, lowers the linguistic self-confidence of the divergent reader, causing him or her to be hesitant in learning, and because of this hesitancy the basic false assumption of the teacher seems to be validated in the teacher’s eyes, i.e. the divergent speaker has reading difficulties. Though vernacular does have an impact on reading skills (as well as writing

The Ability to Perceive a Minor Change in Luminosity Lab Report

The Ability to Perceive a Minor Change in Luminosity - Lab Report Example To perform the CS test (CST), the basic requirements for all four tests were: 1) to have an adequate luminance level required for each test; 2) to have precise test distance; and 3) to perform each test approximately at the same eye sight level as that of test charts. The CST luminance requirement for Pelli-Robson charts was 60–120 cd/m2, while for Vistech6000 and Cambridge plates the adequate luminance levels were 103–240 cd/m2 and 100 cd/m2 respectively. The Lux value required for Cardiff cards CST was equal to that of the gray background cards. For each test the required Lux level was verified by using a Lux meter. The value of precise test distance varies from test to test. For Pelli-Robson CST the required separation was 1 m. For Vistech and Cambridge plates CSTs, the required separation was 3.048 m and 6 m respectively, and within the acuity limit for Cardiff cards CST (Wood and Wood 1995). After having all basic requirements for each test, the test charts/cards w ere hung vertically on a wall one after the other. To determine CS values, corresponding observations were made: first with the right eye (without any correction), starting horizontally on each line of charts/cards and moving from the left hand side to the right hand side, and then from top to bottom for each letter/symbol on the chart /card. The tests were repeated for a plastic in front of an eye pretended to be a cataract. The tests were concluded when two or three letters/symbols were named incorrectly. The corresponding observations for CS were recorded. The CS function (CSF) value obtained for monocular right eye (RE) testing without cataract through Pelli-Robson CST is 1.95 while with cataract it is 1.65 – a quite lower value (fig. 4 and 5) . From Cardiff CST the evaluated contrast (%) values for monocular.

Defining my identity Personal Statement Example | Topics and Well Written Essays - 500 words

Defining my identity - Personal Statement Example At 19 years of age, I believe the greater part of my life still lies ahead. I know that one day I will no longer be living under my mother’s rules, and that is my motivation as to why I strive to be a better person and avoid struggling in future life. I have built my identity mainly by being determined not to be like many people I know. Some are not in school, doing drugs or serving jail terms. Others messed their lives by getting pregnant while still young. But for me, I am a responsible young adult already doing two part time jobs. Most importantly, I am a future-oriented person. My age, gender and ethnicity often cross over each other in the determination of my identity. At 19, I have seen my age mates succumb to peer pressure, but I am not that kind of a person. The culture shock that I suffered when I joined college could easily have led me into self-destructive habits, like the drug abuse that many teenagers indulge in. Instead, I chose not to go out much, opting to stay at home when not working or in school, as well as limiting the number of friends. Despite living with my mother, I pay my own bills, feed myself buy my own clothes and take care of my own doctor’s visits. Apart from that, I also ensure that I provide food for my sister when there is no food at home. My gender means that I must be responsible since, traditionally, women are home keepers. However, as a result of my uniqueness, I want to enjoy the power of providing for myself, rather than taking up stereotyped gender roles. I want to look at gender and ethnicity differently, and mor e positively when I am more mature, hence the aspect of age defines me in a dynamic manner. Inadvertently, I belong to a specific gender, race and ethnicity. It is not my wish to associate myself with any socioeconomic class because such divides only serve to magnify stereotyped differences. So long as one can be responsible enough, get an education and provide

Modern mosque Essay Example | Topics and Well Written Essays - 2500 words

Modern mosque - Essay Example From the Muslim point of view, a divine Mosques must have various specific pertinent features, they include; features that indicates direction directions of the Qible, which in most cases may also be referred as the Mecca. This indication is usually referred as the Mihrab and should have a specific type of roof according to the requirements of the Islam religion (Wood, 7). The first Mosque that was constructed in Turkey was the Mecca; this was a term used to describe the area that surrounded the Ka’ba. In the Muslim Religion, Ka’ba was considered the holiest shrine in the land. The model by which the early Mosques were developed, took the dimensions of Muhammad’s house, which was located in Madina. The direction with which the Qibla at this time was believed be oriented towards Jerusalem. Moreover, on the left side of the early Qiblas, there were three houses for Muhammad’s wives with three different entries that led to the courtyard, an area where most prayers were held during this time. In approximately 1500 years, the direction of the Qibla was changed so that it could face the orientation of the Mecca. The Madina Mosques had various important functions in the early Muslim society; it accommodated social functions, religious as well as political functions. Judicial roles were also undertaken in the early Mosques; the Muhammad and their families members were also accommodated in the early Mosques. In the early period, rules guiding prayers were not shaped to a specific standard owing to the fact that the prescriptions that are in the Koran developed on a gradual basis from time to time. Evidence has also shown that apart from the Mosques of Madina and Mecca, there existed some other dimensions of Mosques in other parts of the World. Owing to rapid technological advancement in the early period, Mosques began growing rapidly in their complexities as well as their appearances. They assumed

SONY VAIO - Essay Example Moreover, marketing serves as a contact between the firms and customers for the fulfillment of needs of both the parties. Therefore, it needs to be customer-focused in order for the business to be profitable and productive. This paper will be concentrating on assessing the changing needs and wants of customers, the brand-building efforts of the companies and how different companies use the marketing mix to create value for their customers. The term 'Marketing' is a very wide concept including several different sub-concepts in it. It is defined as the process whereby companies identify, analyze and fulfill the needs and wants of customers, involve in value-creation process and focus on building profitable relations with customers in order to get value from them in return (Kotler, Armstrong 2006). In short, marketing is your strategy for allocating resources (time and money) in order to achieve your objectives (a fair profit for supplying a good product or service). (Ed Zimmer 1992) The two important basic concepts in marketing are named as needs and wants, which are the elements of human psychology. It is extremely important to meet the needs and wants of customers to drive sales, which is the basis of most businesses. Needs are necessary for the human survival and one cannot go further in life if deprived from what one needs. While, wants are the extended form of human needs which are backed up by one's culture, personality and social status. In present marketing environment, the needs and wants of customers are constantly changing and shifting. The consciousness about raising living standards, increase in disposable income, changing trends and fashions have moved the consumers' preferences from being traditional towards being modern and advanced. Also, though some customers know what they want, some simply don't know. And some may have an idea of what they want without that necessarily corresponding with what they need. It, therefore, depends on the marketing team to draw the needs and wants out of them in order to devise a plan and accomplish goals. (Tim Millett) Product from consumer's perspective In today's era of increasing marketing management efforts and spread of advanced media, consumers have attached great expectations to the products they consume. The basic objective of a product for the consumers is to satisfy their needs and to be of value for them i.e. a product should be able to deliver the benefits to the customers equal to the costs they have paid for it. The product benefits the customers at three levels: Core Product refers to the basic product and its benefits that consumers are seeking. Actual Product includes the product's outward features like brand name, design,

Cherokee Indians Essay Example for Free

Cherokee Indians Essay The word Cherokee is believed to have evolved from a Choctaw word meaning â€Å"Cave People†. It was picked up and used by Europeans and eventually accepted the adopted by Cherokees in the form of Tsalagi or Jalagi. Traditionally, the people now known as Cherokee refer to themselves as aniyun-wiya, a name usually translated as â€Å"the Real People† sometimes â€Å"the Original People. † Cherokees’ have had a democratic government (Conley, Robert J. 2000). The Cherokees’ first experience with the invading white man was almost certainly a brief encounter with the deadly expeditionary force of Spanish explorer Hernando DeSoto in 1540. English colonial traders began to appear among the Cherokees around 1673. Such interactions produced some mixed marriages, usually between a white trader and a Cherokee woman. There were three main events during the 18th and 19th centuries: war with the colonist in 1711; epidemics of European disease (primarily smallpox); and the continual cession of land in 1775. The Cherokees were forced to sign one treaty after another with the new United States government, each one giving away more land to the new nation. In 1803, President Thomas Jefferson planned to move all eastern Indians to a location west of the Mississippi River, and signed an agreement with the state of Georgia promising to accomplish that deed as soon as possible. Andrew Jackson actually set the so-called â€Å"Removal Process† in motion. Meantime the government had been oing everything in its power to convince Cherokees to move west voluntarily, and the first to do so were the faction known as Chickamaugans (Conley, Robert J. 2000). The history and traditions of the Cherokee Indians of the 17th, 18th, and 19th centuries are inextricably linked to the history and traditions of the white southerners. Many facets of Cherokee lifestyle and other Indian tribes in the Southern United States were modified and adapted from white methodology. Aspects of those cultural features were rooted in Pre-Columbian traditions. The Celtic culture of people who colonized the Southern United States and the culture’s charcterictics were the catalyst of what was arguably the most pivotal event in American History, the War Between the States. Many respected scholars have argued that the Ante-bellum south was different than the north, in its lifestyles, philosophies, and more. The southern states and their populations were undeniably different in nearly every socioeconomic and political aspect from the northern states and their respective populations. The destinies of the white southerners and Indian were connected in many ways. They had a number of common interests, traditions, ideals and goals. Some of these similarities were chance; others were due to an intimate relationship developed over centuries of close contact, a relationship created by the dynamic elements in the Cherokee’s new familiarity with their white neighbors and their culture (Bullard, F. B. 1989). The Cherokee adopted some practices willingly, others were forced upon them and some were already in place in some form in their traditional culture. Charles Hudson speculates in his work that the Cherokee and other tribes adopted the measures of civilization in acquiescence to the inability of the Cherokee to compete militarily with the white populous. The Cherokee and other tribes had adopted the techniques and social concepts of white â€Å"civilization† long before they were encouraged to do so by whites and their military intimidation. For the Indian, all white men were a threat to their traditions and cultural tenets. Use of a caste system was a part of the Cherokees ‘social structures before contacts with whites. The white south created its own social caste system with white planters as the aristocracy and the African slave at the peon (Bullard, F. B. 1989). The colonists who settled in the south were different than their counterparts in the North. The main heritage of the southern colonists was the Celtic in contrast to the English heritage of the colonists who settled in the north. The Celtic heritage these southerner colonists brought to North America from Europe had a profound effect on their folkways as well as influencing their Indian neighbors. Traditional Cherokee lands had incorporated ass of Kentucky, much of Tennessee, Georgia, South Carolina, Alabama, North Carolina and a small part of Virginia and what is now West Virginia. The spatial proximity was one reason for the development of an identity with the Southern colonist and their institutions and traditions (Bullard, F. B. 1989). Indian agent for the United States, George Butler, commented that he felt the majority of the material progress in the Indian Territory was a result of slavery. The age of masters measured in the distribution in slaves provides evidence for the upward mobility of slavery for the Cherokee. The principal difference from the white south was the treatment of slaves in the Cherokee Nation. The Cherokee avoided mistreatment of the slaves and Major Ridge’s wife Susanna would not even use the word â€Å"slave†. There are many indications that the Cherokee treated their slaves comparatively well, one former slave of Martin Vann, commented that â€Å"they the slaves had to be feed well, clothed well, and housed well to get the best labor attainable from them† (Bullard, F. B. 1989). The most common agents of change among the Cherokee lifestyle were resident traders, missionaries and government agents. The Cherokee Indians modified their traditions for many reasons, among these reasons were: to placate white politicians and land grabbers and reinforce the federal government policies, philanthropists who wanted to â€Å"civilize† them and most important of all voluntary adaptation in an effort to preserve at least some government policies (Bullard, F. B. 1989). Cherokee Indians religion: It would be a mistake to see these two Cherokee spirit worlds as heaven and hell. They are not defined as good and evil, although the one below is seen as tremendously chaotic. They are thought of simply as being opposed to one another. We live our lives between them in a constant state of precarious balance. This dangerous situation, although the most important aspect of life in this traditional Cherokee view is to maintain balance and harmony. If the Cherokees are Christian, they might be Methodist, Presbyterian, Unitarian, or other Christian denomination. Although the more traditional Cherokees is a large group of Cherokee Baptists. Cherokee Baptists attend what are called Indian churches, where they make use of the Cherokee language (Conley, Robert, J. 2000). Cherokee Indian tribes were one of the largest of five Native American tribes who settled in American Southeast portion of the country. The tribe came from the Iroquoian descent. The Cherokees’ actually lived in cabins made of logs instead of the stereotypical tee pee. Very strong tribe with several smaller sections, all lead by chiefs. This tribe was highly religious and spiritual. Around the 1800’s the Cherokee Indians began to adopt the culture that the white man brought to them. At this time they began to dress more European, and adopted many of their farming and building methods. In 1828 gold was discovered on the Cherokee’s land. This prompted the overtaking of their homes, and was forced out. They had been settled in Georgia for many years, but now they were being made to leave and find a new place to settle/live. This was the historically popular Trail of Tears, where men, women, and children had to pack up their belongings and find new homes, and marching a span of thousands of miles. Today’s Cherokees’ have a strong sense of pride in their heritage (Indians. org 2011). A Historical person during this time Was John Ross in which became principal chief of the Cherokee nation. In 1827, following the establishment of a government modeled on that of the United States. He presided over the nation during the apex of its development in the Southeast, the tragic Trail of Tears, and the subsequent rebuilding of the nation in Indian Territory, in present day. Accompanying his people on the â€Å"trail where they cried,† Ross experienced personal tragedy. His wife, Quatie, died of exposure after giving her only blanket to a sick child. Once in Indian Territory, Ross led the effort to establish farms, businesses, schools, and even colleges. Even though the Cherokee Nation was torn apart politically after the fight over the removal treaty, Ross clung to reins of power (Moulton, Gary E. 004). In conclusion, Although Cherokee Indians were a very diverse tribe and had very many different talents. They were very spitural and worshiped only one spirit and that was good spirit, and eventually followed christanity. Trail of Tears was a very emotional time for all Cherokee Indians the time when they were forced out and were here before anyone ever settled America. This time for Men, Women, and Children was a shame. My grand dad always take for granted what you have cause someone can take it away in an instant; as they did to the Indians.

Economy Of South Africa Economics Essay

Economy Of South Africa Economics Essay South Africas economy is the largest in Africa and is 24 of its GDP in terms of PPP.A quarter of the population is unemployed and real unemployment rate is 40. South Africa has a comparative advantage in agriculture, mining and various manufacturing products. It has shifted from a primary and secondary economy to an economy driven primarily by the tertiary sector which accounts for an estimated 65% of GDP. Its economy is reasonably diversified with key economic sectors including mining, agriculture and fishery, vehicle manufacturing and assembly, food-processing, clothing and textiles, telecommunication, energy, financial and business services, real estate, tourism, transportation, and wholesale and retail trade. The unemployment rate is over 25%, and the poor have limited access to economic opportunities. Including this many issues such as crime, have in turn hurt investment and growth, having a negative effect on employment. Crime is considered a major constraint on investment. South Africa has struggled through the late 2000s recession, and the recovery has been largely led by private and public consumption growth, while export volumes and private investment have yet to fully recover. The long-term potential growth rate of South Africa under the current policy environment has been estimated at 3.5%.Per capita GDP growth has proved mediocre, though improving, growing by 2.2% over the 2000-09 decade. This is a table of the trend of South Africas gross domestic product at market prices estimated by the  International Monetary Fund: Year GDP, USD bln US Dollar Exchange in early January Unemployment rate Per Capita Income,  % of USA 1980 80.547 0.8267 Rand 9.2 22.6 1985 57.273 2.0052 Rand 15.5 9.8 1990 111.998 2.5419 Rand 18.8 13.1 1995 151.117 3.5486 Rand 16.7 13.2 2000 132.964 6.1188 Rand 25.6 8.5 2005 246.956 5.6497 Rand 26.7 12.4 2010 363.655 7.462 Rand 24.9 15.5 2015 (fcast) 510.937 22.8 18.0 Economic overview of South Africa (Sector wise) Natural resources Mining has been the main driving force behind the history and development of Africas most advanced and richest economy. Large scale mining started with the discovery of a diamond on the banks of the Orange River in 1867 by Erasmus Jacobs and the subsequent discovery and exploitation of the Kimberley pipes. The Witwatersrand Gold Rush and the subsequent rapid development of the gold field are the biggest of all. Though minings contribution to the national GDP has fallen from 21% in 1970 to 6% in 2011, it represents 60% of exports. The mining sector accounts for up to 9% of value added. In 2008, the countrys estimated share of world platinum production amounted to 77%; kyanite and other materials, 55%; chromium, 45%; palladium, 39%; vermiculite, 39%; vanadium, 38%; zirconium, 30%; manganese, 21%; rutile, 20%; ilmenite, 19%; gold etc. It also accounted for nearly 5% of the worlds polished diamond production. The countrys share of world reserves of platinum metals amounted to 89%; hafnium, 46%; zirconium, 27%; vanadium, 23%; manganese, 19%; rutile, 18%; fluorspar, 18%. It is worlds third largest exporter of coal. Agriculture and food processing The agricultural industry contributes 10% of formal employment, relatively low compared to other parts, as well as providing work for laborers and contributing 2.6% of GDP. Due to the aridity of the land, only 13.5% can be used for crop production. Agriculture sector face problems of increased foreign competition and crime. Maize production, which contributes to a 36% has also experienced negative effects due to climate change. South Africas critical exports include edible fruit and nuts, beverages, preserved food, tobacco, cereals, wool , miscellaneous food, sugar, meat, milling products and starch. Important imports include: cereals, meat, soya-bean oil cake, soya-bean oil and its fractions, tobacco, palm oil and its fractions, spices, coffee, tea, and preserved food. The competitive pressures from China and India resulted in decline of exports for the food, textiles and paper sub-sectors. Manufacturing The manufacturing industry contributes just 13.3% of jobs and 15% of GDP. Labor costs are low, and the cost of the transport, communications and general living is higher. The automotive industry is about 10% of South Africas manufacturing exports, contributes 7.5% to the countrys GDP. BMW, Ford, Volkswagen, Daimler-Chrysler, General Motors and Toyota all have production plants in South Africa and the large component manufacturers are Arvin Exhaust, Bloxwitch, Corning and Senior Flexonics. Companies producing in South Africa can take advantage of low production costs and access to new markets due to trade agreements with the European Union and the Southern African Development Community. Service industry Telecommunications infrastructure provides efficient service to urban areas as to cellular and internet services. In 1997, Telkom, was partly privatised and entered into a strategic equity partnership with SBC, a U.S. telecommunications company. In exchange of providing certain services for 5 years, Telkom assumed an obligation to facilitate network modernisation and expansion into the unserved areas. Five companies provides service to 20 million subscribers and South Africa considered to have the 4th most advanced mobile telecommunications network worldwide. Business process outsourcing South Africa and particularly the Cape Town region established itself as a successful Call center and business process outsourcing destination with a highly talented pool of productive labor. The Carphone warehouse, Delta airlines and others have established inbound call centers within Cape Town as a means of utilizing Cape Towns low labor costs and talented labor. Tourism South Africa is a popular tourist destination, with around 860,000 arrivals per month. Revenue equaling between 1% and 3% of GDP is generated by the tourism industry. Among the main attractions are the picturesque culture, the game reserves and local wines. Financial services The country has a sophisticated financial structure with the JSE Securities Exchange, a large and active stock exchange in terms of total market capitalization as of March 2009. The banking industry regulated by the South African Reserve Bank is dominated by four local players: Nedbank, ABSA, Standard Bank and First Rand. Banks operating in South Africa, when left with short of liquidity, need to borrow from the SARB at a fluctuating repo rate. Income Distribution South Africa is affected by vast differences in incomes and wealth. The high level of overall income inequality has accentuated: the countrys Gini coefficient increased by four percentage points, and income has concentrated in the top decile. Rural poverty rates remain higher than those in urban areas, urban poverty rates are rising and rural rates seem to be falling. Between-race inequality also remains a central issue and many blacks in the country still live in poverty. National Income Dynamics Study (NIDS) data suggests that 47% of South Africans live below the poverty line: 56% of blacks live in poverty compared to 2% of whites. Human Poverty Index ranked South Africa 85 out of 135 countries. A 2011 study published by the University of Cape Town found that nearly 40% are black, where this group had once been almost exclusively white. While only 29% of the absolute wealthiest South Africans are black, this jumps to 50% among the entry-level. Current Economic scenario Trends: Monetary Policy   The primary objective of monetary policy in the country is to achieve and maintain price stability and balanced economic development. Price stability reduces uncertainty and therefore, provides a favourable environment for growth and employment. Moreover low inflation contributes to the protection of the purchasing power of all South Africans specially poor. The Bank has full operational autonomy. Monetary policy is set by the Banks Monetary Policy Committee,  which conducts monetary policy within a flexible  inflation-targeting framework and  it allows for inflation to be out of the target range as a result of first-round effects of a supply shock. This flexibility does not relieve the Bank of its responsibility with respect to returning inflation to within the target range but allows for interest rate smoothing over the cycle.

The report said FDI inflows to South Africa fell to $1.7-billion in the first six months of 2012 , reflecting sluggish domestic economic growth as well as a slowdown in developed economies. The IMF forecasts South African GDP growth of 2.6% this year, and recently cut its 2013 growth forecast to 3% from a July projection of 3.3%, due to its close links to struggling Europe.

Horrifying Effects of a Senseless War :: essays papers

Horrifying Effects of a Senseless War Dirty Work is an irresistible debut novel from one of the greatest novelist in American literature today. Throughout each chapter, Larry Brown creatively changes the narrator between the two main characters, which works magnificently. He is bold and decisive in his telling of two disabled individuals being tormented by the physical and emotional hell they withstand in the everlasting Vietnam. Braiden Chainey has no arms or legs due to a machine gun (73). Walter James, thanks to a rocket grenade, no longer has his face (66). As they lay side by side in their separate beds in a V.A. hospital 22 years later, their wounds still ache. These two Mississippians, one white and one black, tell each other their horrendous stories. One by one, they take turns describing the details of their lives and the outcome wanted for their future. Many old themes of literature are invoked in this astonishing tale of hatred, emotion, vengeance, and even passion. Their vivid memories portray the true reality of how that horrifying war gave the veterans the unforgettable long-term effects. Dirty Work is an extraordinary novel, which continuously shows the harsh realities of a powerful war. The two main characters in this novel are compelling. Every feature and emotion mentioned about each individual are so realistic that they are unforgettable. From their family background to their scars of war, each and every aspect is told with such detail and brilliance that the story almost comes to life. Brown utilizes southern slang to the greatest. When Braiden and Walter speak to each other, they perfectly mimic the mistakes and shortenings of everyday southern speech. Most of the dialect indicates brilliantly the way that people whom the author might have encountered at times in his life may have spoken. In one passage, Walter speaks with a nurse, showing their strong southern culture coming out through speech: â€Å"Where’d you learn that song?† â€Å"Known that all my life, So you one of them Missippi boys, huh?† â€Å"Nothing but.† (114) Dirty Work is strongly in the tradition of a classic war book with some southern heritage.

British Settlement in American Continent and Regionalism :: Geography History Historic Essays

British Settlement in American Continent and Regionalism Describe how settlement patterns set-up the regionalisms of the United States. Throughout history, people from cultures around the world have come to America seeking a new life or a change from their current conditions. They may have come to avoid persecution, to avoid overpopulation, or to attempt to be successful in an entirely new world from the life they formerly knew. As the immigrants arrived, some found that their dreams had been attained. Conversely, some found that the New World was not as fantastic as they were led to believe. In the seventeenth and eighteenth centuries, an influx of British citizens arrived on the shores of America. The arriving British population came from a particular area of Europe, but there was distinct individuality within the group. The diverse British immigrant population would be the first of many groups to add cultural variety to the United States population, for which America continues to be known today. After reading Albion's Seed by David Hackett Fischer, it is apparent that the four major British groups arriving from 1620 to 1776 and their patterns of settlement would shape the development of American regionalisms known throughout the country. Four major British groups immigrated to America within a span of less than two hundred years. Although they all migrated from the British Isles, each had a distinct set of standards and a very set culture carried from the other side of the Atlantic. Not only were the people of early America diverse, so were the motives for which they migrated to the New World. The Puritans arrived from 1629 to 1641. This group was a culture devoted to the Bible and following its every word. Because of their extreme beliefs, they had been persecuted in England. Their goal in America was to create a Promised Land based on their beliefs. They moved from the eastern sections of Britain known as East Anglia and settled in New England, primarily in Massachusetts. The Puritans' influence shaped the New England image to how it is known today. For example, the pattern of settlement of small towns in the New England region was carried over from those of eastern England. These towns were centralized along a main road, with a few farms or homes outside of the village. Even today, this type of town is well known throughout Massachusetts and the other New England states. Another example of well-known New England characteristics concerns their food preference.

Creating Tension and Drama in the Courtroom in The Crucible Essay

Creating Tension and Drama in the Courtroom in The Crucible The crucible is about a mass hysteria which led to the 1692 Salem witchcraft trials. A group of young girls are caught dancing in the woods and are suspected to of been calling out to the devil. Strange things begin to happen around the local village which are then suspected to be the work of the devil. Everyone in the village is to appear in court and faced with a death sentence. This fantastic and extremely tense play is written by Arthur Miller. Throughout Act Three Danforth; the deputy governor, who is in his sixties and plays an important part, is introduced. He is very sophisticated and respectful. Danforth plays the part of a very loyal man in which he makes antagonising decisions. However he is a very strong character and has his own opinions without being easily persuaded. Danforth has high expectations of both himself and his people. ’ I judge nothing of no one’ This tells the audience what Danforth’s character is like; a strong and noble man, and he will be looked upon as loyal man who has pride in which he can make his mind up for himself without listening to what others have to say. During Act Three Mary Warren plays a main part of a quiet girl who is made to confess by John Proctor that they girls are faking it and being over powered by the devil. Mary Warren who works for the Proctors has a good reputation. She has never done wrong, and is a hard working quiet girl. Mary is forced into court by Proctor to confess the truth. She speaks short words which shows fear. ‘ it were pretence sir’ ‘ aye, sir.’ Mary’s weakness causes tension as she is a weak character being forced to speak out by Proctor. Proctor mainly speaks... ...tly leaving the reader in suspense. My favourite scene was when Elizabeth was called into the court to justify Proctors accusation of lechery against Abigail. It gave the reader an unsure feeling of what the turn out would be like and what was going to happen next, this created more tension in this particular scene. I thought the ending was good and Act 3 was a fantastic build up for this dramatic ending. I think Miller’s intention of scene 3 being so dramatic was to build of for the ending which was not what I would have expected to of been like. This is good because it makes the reader want to read on. Miller was definatly successful in writing this play, he gave me the message, of what it was like back then, very strict and strong about there beliefs and witch craft. I think people would have definatly learnt from this story which is very strong.

Stefan’s Diaries: Bloodlust Preface

And the TV series developed by Kevin Williamson & Julie Plec Tis now the very witching time of night, When churchyards yawn and hell itself breathes out Contagion to this world. Now could I drink hot blood And do such bitter business as the day Would quake to look on. –Hamlet, William Shakespeare Preface The poets and philosophers I once loved had it wrong. Death does not come to us all, nor does the passage of time dim our memories and reduce our bodies to dust. Because while I was considered dead, and a headstone had been engraved with my name, in truth my life was just beginning. It was as if I'd been asleep these many years, slumbering in the darkest night, only to awake to a world that was brighter, wilder, more thrilling than I'd ever imagined. The humans I used to know continued their lives, just as I once had, spending their finite days going to the market, tending the fields, stealing secret kisses when the sun went down. They were merely shadows to me now, no more significant than the frightened squirrels and rabbits that scampered in the forest, barely conscious of the world around them. But I was no shadow. I was whole–and impervious to their worst fear. I had conquered death. I was no fleeting visitor to the world. I was its master, and I had all of eternity to bend it to my will.

Insomnia and Dreaming

For the occurrence of dreams, an uninterrupted period of sleep is needed. So if the quality of sleep declines, the dream recall frequency will decline as well. As experiments shown us, people of mood disorder and depression have a reduced dream recall frequency. Also people having Apnea and increased daytime sleepiness, CNS and PLM will have the same results which are a decline of sleep quality and a reduced dream recall frequency. Insomnia is the most frequent, it is considered as a symptom and it is a subjective dissatisfaction with sleep, also difficulty with sleep initiation and sleep maintenance. The stages may look like this, increased sleep latency, increased awakenings and arousals, decreased sleep efficiency, increased time of wake after sleep onset, decreased total sleep time, decreased rapid eye movement sleep (REMS) and decreased deep sleep in stages 3 and 4. A study on 289 people have showed over a 6 year period in the life of the experiment, that there is a comparison between individuals reporting insomnia to those reporting no insomnia. Those reporting were 141 and those none reporting were 148 individual. The only difference was in the nightmare recall frequency that was found higher in the insomnia group. Also this finding took into consideration people taking medications and those who were not taking any sort of medication inside the reporting insomnia group. A decrease in dream recall was shown; a decline in dream recall is recorded with disordered sleep. Those with sleep latency more than 30 minutes reported a decline in dream recall. As for sleep effiency the groups with a higher percentage (85%) had more dream recall frequency than others. Individuals with a WASO (wake after sleep onset), of higher than 60 minutes had a lower dream recall than others. Also stages 3 and 4 showed a significant decline for the group reporting insomnia. As a result, people with 360 minutes of continuous sleep have an increased nightmare and dream recall. As a conclusion, dreaming requires a minimum quality of continuous sleep. People reporting insomnia has lower levels of dream and nightmare recalls. I can not say that I had a personal experience in insomnia. But surely I saw close people in my family having this problem. When I used to live in my grandparents house, I used to notice how my uncle would wake up in the middle of the night after slept for a maximum of an hour. He used to walk around the house for a while, than take out his collection games that he used to build and try to reshape them. He would do this for a couple of hours before returning to bed. I might say that I noticed how he would wake up in a bad mood. Also when he was asked to remember certain events and details it would take him a while. I think his changeable mood as a result of sleeping for a very limited number of hours may have affected his way of thinking. Also I noticed how he would sleep for several hours during the day to compensate the lost sleepless nights. As a direct effect, my uncle started taking bad decisions in his field of work and was finally advised to see a physician. These days after seeing the difference I realized that I was right in describing his insomnia at the time. Reference: Pagel, J.

Community Living Covenant Essay

Upon beginning a new chapter in my life and entering my first year of college, I have a strong desire to attend a school in which my Christian values will be respected, and also where I can learn and grow in my faith. Because my life already parallels the expectations set forth in the covenant, I do not feel living up to these standards will be difficult. In fact, I embrace the idea that I will be surrounded by others who hold the same morals and values that I do. In that sense, it will make the transition into college life a much easier one. I look forward to learning academically, as well as spiritually through the chapel services and Bible studies. Attending religious classes and mission trips is also an exciting prospect for me. Perhaps the only challenge that I can anticipate at this time is that of leaving the covenant upon graduation and entering into a secular world that does not always support my Christian way of life. However, I feel that the knowledge I gain from attending Point Loma will equip me with the skills necessary to contribute to society as well as maintain my relationship with Christ.

The definition and difference between PQ Bus and PV Bus are described as follows ; [ 2 ] PV Bus ( Generator Bus or Voltage Controlled Bus ) : It is a coach at which the magnitude of the coach electromotive force is kept changeless by the generator. Even though the coach has several generators and burden, if any generators connected to the coach modulate the coach electromotive force with AVR, so this coach is referred to PV Bus. For PV coach, the magnitude of the coach electromotive force and existent power supplied to the system are specified, and reactive power and angle of the coach electromotive force are consequently determined. If a preset upper limit and minimal reactive power bound is reached, the reactive end product of the generator remains at the limited values, so the coach can be considered as PQ Bus alternatively of PV Bus. [ 2 ] PQ Bus ( Load Bus ) : It is a coach at which the electromotive force is changed depending on entire net existent power and reactive power of tonss and generators without electromotive force regulator. Therefore, in the power simulation and computation, the existent power and reactive power of the tonss are specified as input informations and consequently the electromotive force ( magnitude and angle ) is calculated based on the above input. The following table specifies input and end product of each coach type in the power system simulation and computation. Bus Type Phosphorus Q ( Magnitude ) I?

In add-on, the entire power system is wholly balanced, because entire coevals power ( existent & A ; fanciful ) are equal to summing up of entire load demand and existent power loss & A ; stored fanciful power over the transmittal ( i.e. Pgen – Pdemand = Plosses, Qgen – Qstored in burden = Q stored in system ) as shown above.Voltage Angle and Angle DifferenceAs a consequence of the Powerworld, the electromotive force angle and angle difference are shown in the tabular array below.BusVoltage AngleVoltage Angle DifferenceBUS1 I?1 = 0.00A ° BUS1- BUS2 I?1 – I?2 = 0.00A ° – ( -2.5662A ° ) = 2.5662A ° BUS2 I?2 = -2.5662A ° BUS2- BUS3 I?2 – I?3 = -2.5662A ° – ( -0.043A ° ) = -2.5232A ° BUS3 I?3 = -0.043A ° BUS3- BUS1 I?3 – I?1 = -0.043A ° – 0.00A ° = -0.043A °Power System Analysis -1The tabular array below summarizes coevals and electromotive force angle fluctuation at each coach as coevals at Bus 3 varies from 0 MW to 450 MW by 50MW.Simulation Consequences and ObservationP3 = 0 MW P3 = 50 MW P3 = 100 MW P3 = 150 MW P3 = 250 MW P3 = 300 MW P3 = 350 MW P3 = 400 MW P3 = 450 MW Reactive Power Generation at Bus 3: It is found that reactive power coevals Q3 ( gen ) lessening while existent power coevals P3 ( gen ) addition because Bus 3 as a PV Bus regulates the changeless coach electromotive force magnitude by commanding excitement of the coevals through the AVR. Power Generation at Bus 1: It is found that P1 ( gen ) decreases and Q1 ( gen ) increases at the same time, while P3 ( gen ) additions and Q3 ( gen ) lessening. As the entire load demand in the system keeps changeless ( i.e. Ptotal ( burden ) = 400 MW, Qtotal ( burden ) = 150Mvar ) , any necessary existent power and reactive power for the system balance demand to be supplied by generator ( loose generator ) at Bus 1. Therefore, power coevals P1 ( gen ) and Q1 ( gen ) at Bus 1 alteration reversely compared to power coevals alteration at Bus 3. Voltage Angle Difference: In general, existent power flow is influenced by electromotive force angle difference between directing coach and having coach harmonizing to PR = . Therefore, it is observed that every bit existent power coevals P3 ( gen ) increases existent power flow from Bus 3 to Bus2 addition, consequently voltage angle difference ( I?3 – I?2 ) between Bus 3 and Bus 2 additions. However, lessening in existent power from Bus 1 to Bus 2 due to increase of P3 ( gen ) consequence in lessening of electromotive force angle difference ( I?1 – I?2 ) . In add-on, Real power between Bus 1 and Bus 3 flows from Bus 1 to Bus 3 until P3 ( gen ) range to 200 MW and as P3 ( gen ) addition more than 200 MW the existent power flows from Bus 3 to Bus 1. So, it is besides observed that electromotive force angle difference ( I?3 – I?1 ) is negative angle when P3 ( gen ) is less than 200MW and the difference addition while P3 ( gen ) addition.Power System Analysis -2The tabular array below summarizes the fluctuation of power coevals and electromotive force angle difference at each coach when the burden demand at Bus 3 varies by 50MW and 25Mvar.Simulation Consequences and ObservationP2 = 0 MW Q2 = 0 MW P2 = 50 MW Q2 = 25 MW P2 = 100 MW Q2 = 50 MW P2 = 150 MW Q2 = 75 MW P2 = 250 MW Q2 = 125 MW P2 = 300 MW Q2 = 150 MW P2 = 350 MW Q2 = 175 MW P2 = 400 MW Q2 = 200 MW P2 = 450 MW Q2 = 225 MW Power Generation at Bus 1 and Bus 3: It is observed that as the entire load demand in the system increases due to increase of load demand P2 ( burden ) & A ; Q2 ( burden ) at Bus 2, any necessary existent power for the system balance is supplied by generator ( loose generator ) at Bus 1 sing changeless P3 ( gen ) , so P1 ( gen ) increases. In add-on, any necessary reactive power for the system balance is supplied from Bus 1 every bit good as Bus 3, so both Q1 ( gen ) and Q3 ( gen ) addition. Voltage Angle Difference: It is found that existent power flow addition both from Bus 1 to Bus 2 and from Bus 3 to Bus 2 due to increase of load demand at Bus2. Consequently, both electromotive force angle difference I?1 – I?2 and I?3 – I?2 addition when the power flow P12 and P32 addition. In add-on, when P2 ( burden ) is less than 200 MW, P1gen is comparatively low. Therefore existent power between Bus 3 and Bus 1 flows from Bus 3 to Bus 1 at lower P2 ( burden ) ( less than 200MW ) . On the other manus, while P2 ( burden ) addition more than 200 MW, the existent power flow way alterations ( Bus 1 to Bus 3 ) and the existent power flow additions. Consequently, the electromotive force angle difference I?1 – I?3 alteration from negative to positive and addition. Voltage Magnitude at Bus 2: It is observed that magnitude of coach electromotive force at Bus2 beads due to increase of the load demand at Bus 2.Question 2System Model & A ; Admittance MatrixIn order to build the entree matrix of Powerworld B3 instance, individual stage tantamount circuit can be drawn as below ;omega = R + jx ( r = 0, x = 0.05 )z12 = z21= j0.05 plutonium, y12 = 1/ z12 = 1/j0.05 = -j20 plutonium = y12 z13 = z31= j0.05 plutonium, y13 = 1/ z13 = 1/j0.05 = -j20 plutonium = y31 z23 = z32= j0.05 plutonium, y23 = 1/ z23 = 1/j0.05 = -j20 plutonium = y32 Admittance matrix can be defined as follows ; BUS = Diagonal elements Y ( I, I ) of the entree matrix, called as the self-admittance [ talk slide ] [ 6 ] , are the summing up of all entree connected with BUS I. = y12 + y13 = -j20 – j20 = -j40 plutonium = y21 + y23 = -j20 – j20 = -j40 plutonium = y31 + y32 = -j20 – j20 = -j40 plutonium Off diagonal elements Y ( I, J ) of the entree matrix, called as the common entree [ talk slide ] [ 6 ] , are negative entree between BUS I and BUS J. = – y12 = – ( -j20 ) = j20 plutonium = – y13 = – ( -j20 ) = j20 plutonium = – y21 = – ( -j20 ) = j20 plutonium = – y23 = – ( -j20 ) = j20 plutonium = – y31 = – ( -j20 ) = j20 plutonium = – y32 = – ( -j20 ) = j20 plutonium Therefore, the concluding entree matrix BUS is ; BUS = = The undermentioned figure shows the BUS of the Powerworld B3 instance and it is verified that the deliberate entree matrix is consistent with the consequence of the Powerworld.Power Flow CalculationNodal equation with the entree matrix can be used to cipher electromotive force at each coach if we know all the current ( i.e. entire coevals power and load demand at each BUS ) and eventually the power flow can be calculated consequently. , hence, In this inquiry, nevertheless, simulation consequences of the electromotive force at each coach from the Powerworld are used for the power flow computation as follows ; [ Simulation consequence ]Voltage at each Bus and Voltage DifferenceV1 = 1 a? 0.00A ° plutonium ( BUS1 ) V2 = 1 a? -0.48A ° plutonium ( BUS2 ) V3 = 1 a? 0.48A ° plutonium ( BUS 3 )Voltage difference between BUS 1 and BUS 2V12 = V1 – V2 = 1 a? 0.00A ° – 1 a? -0.48A ° = 3.5 x 10-5 + J 8.38 ten 10-3 = 8.38 ten 10-3 a? 89.76A ° plutonium V21 = V2 – V1 = – V12 = – 3.5 ten 10-5 – J 8.38 ten 10-3 = 8.38 ten 10-3 a? -90.24A ° plutoniumVoltage difference between BUS 3 and BUS 2V32 = V3 – V2 = 1 a? 0.48A ° – 1 a? -0.48A ° = J 16.76 ten 10-3 = 16.76 ten 10-3 a? 90A ° plutonium V23 = V2 – V3 = – V32 = – J 16.76 ten 10-3 = -16,76 x 10-3 a? -90A ° plutoniumVoltage difference between BUS 3 and BUS 1V31 = V3 – V1 = 1 a? 0.48A ° – 1 a? 0.00A ° = – 3.5 ten 10-5 + J 8.38 ten 10-3 = 8.38 ten 10-3 a? 90.24A ° plutonium V13 = V1 – V3 = – V31 = 3.5 ten 10-5 – J 8.38 ten 10-3 = 8.38 ten 10-3 a? -89.76A ° plutoniumLine CurrentCurrent flow from BUS I and BUS J can be calculated by utilizing electromotive force difference and interrelated entree of the line between coachs.

HomeLand Security Strategies - Research Paper Example This reaffirms that America is committed to pursue its interests by the use of an international system where all countries have specific rights and responsibilities. The paper will discuss the homeland security strategies focused on the safety and security of the citizens of America. This is attributed to the fact that there have been enormous threats to American citizens than weapons of mass destruction, especially the danger posed by the pursuit of nuclear weapons by violent extremists and their proliferation to neighboring states. As noted by Reddick (2010) the National Security Strategy which was released in May, 27 2010 rolled out a strategic approach for the advancing American interests including the security of the American citizens, improving American economy, and supports their values, as well as an international order that tackles the challenges of the 21st century. The strategies include: Defeating terrorism globally After the September 9/11, terrorism attacks the United S tates has made significant steps in ensuring the safety of the nation. It formed the foundation of Department of Homeland Security (DHS), whose functions took a new organization and urgency. Their approaches now included: restricting hostile actors the capability to operate within the American borders; shared efforts to determine and interdict threats; maintaining effective control of our physical borders; ensuring national resilience in the face of the hazards and threats; safeguarding lawful trade and travel into and out of United States of America. The DHS and many of its partners locally, regionally, and internationally as well as the communities have strengthened the homeland security enterprise to mitigate and defend against dynamic threats. Their core strategic objectives include: comprehending the threat, deterring and disrupting operations, protecting against terrorist capabilities, stopping the spread of violent extremism, and increasing community participation in order to deter terrorists and alleviate radicalization towards violence. According to DHS (2012) it reported that its efforts to prevent terrorism are centered on a layered risk-based approach to the security in the cargo and passenger systems of transportation, borders, and ports of entry.   It consists of new technologies to: help detect explosives and other dangerous weapons; aid in the protection of critical infrastructure and cyber networks from attack; build partnerships in information sharing. According to Guiora (2011) found out that DHS works in corporation with many partners in countering violent extremists. These extremists cause a great threat to national security. The DHS has initiated the following programs to counter violent extremists: international partnerships with other countries like Canada, Spain, Belgium, and Germany; conducting joint workshops and conferences of law enforcement agents; and provision of grants to the support of law enforcement efforts. Terrorist acti vities that may occur due to explosives are cut out by DHS’s work through enhancing the counter-IED capabilities of the nation and reduce the threat of explosive attack. Moreover, terrorist activities are prevented through: building of the homeland security enterprise which has fusion centers, nationwide suspicion activity reporting initiative, presence of homeland security

Video Evaluation Essay Example | Topics and Well Written Essays - 1500 words

Video Evaluation - Essay Example This is a very discouraging concept to believe (Molyneux 2013). Prior to watching this video, it was to my understanding that social programs helped the poor people. I thought that the job forecast was actually increasing. I knew that our government was in over its head with debt but I presumed it was due to our country’s intervention in the Middle East. I believed that the middle class actually were living paycheck to paycheck and I did believe many lived off of credit cards and loans. However, I did not really realize that what they had spent was money they did not have in the first place. At the rate that this economy is moving, there is little to no hope of changing. I had no idea that we were so much worse off economically than we were in the 1950s and while it is easy to blame the President, the majority of the issues are also to be blamed on Congress. I discovered by watching this video, I was quite wrong about many of my theories about our economy. There is much to be learned from this video. The statistics are extremely eye-opening. When looking at the graphs and charts that Molyneux had created, it is evident that many thing that the government are doing to try to help increase the recovery process are actually failing. Programs that were established over 40 years ago are haunting the country today as people who do not work and live off the government are making more than those who do work. The debt is increasing per household, per corporation and also federally. People are spending imaginary money that they simply do not have. The wages people are making are spent on their debts. Items are increasing in price while what they make per hour cannot cover the prices of goods that people need. Many people are living well below poverty level. Actually, it appears that the people who are on welfare are sitting better economically than the people who are actually working to

Theory, Research, and Managerial Applications Essay - 2

Theory, Research, and Managerial Applications - Essay Example For instance, the food and drug administration made an approval of a drug into the market yet it knew that the drug had serious negative effects on consumers (Jamshid, 2005). The article shows that the drug had a significant number of warning signs, which could have been avoided early enough. Merck and FDA failed to meet their responsibilities to the public; there was also a failure to submit the data to a peer-reviewed periodical and the cardiovascular information provided in the article were half-finished. As a skilled leader, such issues would not have occurred because of the knowledge the leader had regarding the drug. FDA did not take any skill to ensure that the drug underwent various trials before being approved, despite the fact that it had the command to do so. Systemic is the process that leads to almost all of a system is affected instead of a small section of the system. In terms of medicine, systemic implies influencing the whole body instead of one organ or body part (Matteson, 2007). On the other hand, systemic implies that occurring from the structure of the system and influencing the entire behavior of the whole system in systems thinking (Russell, 2010). Therefore, a problem is systemic if the conduct of most or all of its significant sections is affected. The systemic issues from the case study include the consumption of Rofecoxib drug, which resulted in affecting a large number of people who used the drug. Another issue includes the failure of the leadership at the FDA to acknowledge that they are responsible for the health of the public (Topol, 2004). In addition, Merck was only concerned in the sale of Rofecoxib despite its possible cardiovascular toxicity and the robust signs that there was an issue and that a large number of people were being exposed. The most appropriate strategy for system improvement utilizing systems thinking includes altering the essential method a system works, through transforming the framework of its main response loops. Just like from the case study, there was the withdrawal of the drug from the market after realizing it was harmful for public consumption.

Slip & Fall - Assignment Example Hence the defense is correctly drawn as far as the grocery store rules are concerned. The bag boy had done his duty which is important to consider in defense of the grocery store. Ann is being emotional in her response because it was her mistake in the first place and the grocery store should not pay for her lapse in concentration. Also the fact that she did not read the wet floor sign and disregarded it was her own mistake, which needs to be understood on the part of the court. Hence suing the grocery store for damages is unwarranted and does not merit a case at all. Ann should have known better where she is in the wrong and what kind of error she has committed in bringing her downfall (Biggermann, 2010). The grocery store did everything to make sure that she did not cross the barrier but putting up the wet floor sign but if she did not read it, then it is solely her own mistake and the store must not be blamed for it. Also the fact that many customers visit this grocery store on a daily basis is enough for the court to understand that a grocery store can just do so much. The customers need to be wary of the signs that are put up at such places and find out where they are going wrong or committing mistakes. This will put them at ease as far as slipping and falling down dynamics are concerned. It is important that the court considers the defense of the grocery store management as well before reaching on to a decision. The facts are there for the court to see and analyze, and now it is the responsibility of the honorable court to reach a decision which is based on impartiality and fairness. Ann must have known she is not following the proper rules and procedures within the grocery store and this is one aspect that should not have lingered on to such proportions. However, this unfortunate event took place much to the agony
