buy custom World Religion Class Research Paper essay The world as we know or tend to know it is a haven of beliefs. Everyone would like to believe that he/she worships or believes on a more powerful being than the other. However, there is a problem going by that angle of belief. This is not the period when God or gods used to speak to people through prophets and other divine characters. The problem of these beliefs is brought by the fact that the faithfuls of the different religions cannot prove that they are actually worshipping the right being or that their god is more powerful than that of another group. To distinguish the purpose of one religion from that of another would be a tiresome commitment. However, by investigating the Christian religions and the secular religions, a number of similarities in their beliefs would help determine the likelihood that they worship the same being but in variety of ways. This is a research paper whose aim is to determine a number of similarities within the secular and the Christian religions. To Christians Jesus Christ is their savior and to get to God, they believe that they must honor Jesus first. The holy trinity is another of the Christians beliefs that tend to bring a sense of equity but to only a section of the Christian race. Islam on the other hand can be taken as one religion with multiple of teachings. The same way that Catholics and Protestants dont agree on their interpretations of the Holy Bible, Islam has its partitions which read the same Quran but interpret it differently hence drawing in a situation similar to that of Catholics and Protestants. What connects the Christians and the Islam religions is not what they teach but the belief that between them and God there is a link, incarnation and prophesying are methods that God uses to speak to them, and the human existence is made possible by the will of a supreme being. The Link between God and Humans From time immemorial, objectification of God has been a practice for many religions. It is understood that God uses an army of angels and uses prophets to communicate with the world. To draw the objectification point from that, we look at the holy rosary that is used by Catholics and a number of other religions. The holy rosary has been taken by several churches to represent God. The presence of the cross and/or a curving of what is assumed to be Mary mother of Jesus show that objectification is a way of finding a link between human beings and God. When praying, most of the Christian faithfuls who use the rosary tend to think that it is in the best interest of them to incorporate the rosary. This creates a link assumed to get Gods attention and somewhat drawing in a sense of assurance that their prayers would be answered (Brodd, 2003). Who is Mohammed? Who is Jesus? What is their importance to the lives of the faithfuls who believe in the religions they represent? According to the Islam religion, Mohammed was a prophet who created a link a between the Muslim community and God. This context does not play the same role as that of Jesus for Christians. Jesus is the son of God according to the bible and the beliefs of Christians. To the Muslims who follow theteaching of the Quran with a clear mind, Jesus was also a prophet just like Mohammed. The reason why Muslims believe Jesus was a prophet is because they object the claim by Christians that Jesus was Gods son sent to deliver Jews from sin. The argument by Muslims that Jesus was a prophet is logical due to the fact that in both the Quran and the Bible all people are equal before God. So if God saw it important to make a link between Him and Muslims, then he must have seen it important to create a link for every race. Jesus for the Jews and Mohammed for the Muslims ma kes an impression which stand to be questioned logically; if Jesus represents Jews and Mohammed represented Muslims and they are son and prophet respectively before the eyes of God, why is the imbalance between the two races so pronounced (Shrotri, et al. 1999). There is no point in trying to question why God or the supreme being of whichever religion chose to do things in a certain way or another. Imagining like a god is way off the league of humans, but humans themselves tend to make their own symbols which they believe act as channels of connection between God and themselves. The Cow for Hindus, the Rosary for Catholics, the beads and beards for the Muslim, and shrines for the Buddhists all give the impression that no matter the religion, faithfuls believe on the act of using a person, an animal, an object or assuming a way of life to be close to God. Incarnation and Prophesying The human race is believed to be bound by sin and this is the reason why according to teachings of many religions, there seems to exist a divine power sent to deliver them from sin. In many cultural and social settings, several people and objects are referred to as Gods incarnations to them. The Christian Holy Trinity comprises of the Father, the Son and the Holy Spirit. With sin drawn to the picture, it can be understood that the son is the Gods incarnation to Christians. Developing in the womb of a human to be born as a human in order to save the world (Jews) from sin; the presence of God was brought closer only in a manner made to make the Christian race believe. Arguing from a personal perspective of how it would have been if God chose to represent himself to deliver man from sin; how would it feel like if he introduced himself to Pilate as, Hey, I am God. Different races especially the African traditional settings tend to believe that they have felt the presence of God through a certain elder of their community. Besides what people may assume to be experiencing or believing, hallucination is part of being human. The Hindus do not worship the cow but they assume that the cow is a holy creature responsible for their ways of life. It is believed that Jainism and Buddhism are some of the Indian religions that honor the cow as a holy animal. Is there any aspect of incarnation or prophesy in this belief? We cannot be sure for certain but how about reflecting the teachings and believes of other religions? Christians believe Jesus was the son of God send to earth to deliver Jews from sin. Going with that belief we deduce that the cow in the Indian relligion is Gods incarnation not send to them to deliver them from sin but to help them deal with the day-to-day challenges. The cow in India in used by the Hindus, the Janis, and the Buddhists as a holy animal whose milk nourishes children to a healthy growth, whose dung is a source of energy and an ingredient for the ritual mark on the forehead (tilak). While Christians honor the birth of Jesus Christ by celebrating Christmas, Hindus, Janis, and Buddhist honor the cow with Gopastami (the cow holiday). Brahmans are considered to be high-cast priests whom to their respective duties they are considered prophets in the Hindu religion. Several prophets are used in the Bible to symbolize the use of people by God in connecting with others. Mohammed is considered a prophet in the Islam religion. The faithfuls of all these religions attach special importance to the presence of prophets. They all believe that God work through people to get through to others. The Mormon Church is an example of a secular religion whose doctrines and teachings tend to oppose the teachings of the Quran and the Bible. But conceptually this religion believes that God, prophets and divine elements make up the spiritual world. They believe that God is perfect and they strive to emulate the same. Human Existence and Presence of God Civilization has brought understanding to man in terms of his roots and has laid a foundation for the destination. If we exist now, it means that a much powerful being must have existed before us. Before civilization that took the bible to the Africans, who did the Africans worship? Just like animals, humans have instincts. These instincts work together with the conscious brain to draw reasons as to why things are like they way they are. Both religious and freelancer groups believe or tend to owe their existence to some supreme being. Long before civilization, worshipping was part and parcel of communities all across the world. Even after theories that tend to detach man from Gods creation, it is still believed that a supreme being is responsible for creation or the existence of man. Devil worshippers tend to oppose the teachings of the holy books and tend to honor Lucifer; funny enough they attach the existence of Lucifer to a rather much powerful being. Conclusion People of different denominations owe their existence to some ultimately powerful being. It has been known for ages that the supreme beings responsible for our existence are too powerful that they may cause death if they were seen by us. But in order to make the human race feel close to them and protected, they incarnate themselves to humans and other objects. Neither do we believe in the same teachings nor does our social settings and cultural differences allow for it. This is the reason why there are so many religions in the world. Their teachings are different but all are similar to one another in one way or another. Christians and Muslims believe in the presence of Gods representatives amongst them. Buddhist, Janis and Hindus honor the cow because they believe it is holy and send to them to help them with their day-to-day lives. Buy custom World Religion Class Research Paper essay

Barack Obama, Donald Trump and the Birther Movement
Barack Obama, Donald Trump and the Birther Movement Barack Obamaââ¬â¢s legacy as the 44th U.S. president includes the killing of Osama bin Laden, helping the economy bounce back from the Great Recession and his controversial health care plan, but his time in office will forever be linked to the birther movement as well. Birthers not only framed Obama as an illegitimate president but also paved Donald Trumpââ¬â¢s path to the White House. With this overview, learn the origins of the movement, how it spread, and its effect on Obama. Birtherism in Context Barack Obama was born Aug. 4, 1961, in Honolulu, Hawaii, to a native Kansan mother, Ann Dunham, and a native Kenyan father, Barack Obama Sr. But birthers contend that the president was born in Kenya, like his father. They argue that this made him ineligible to be president. Since Ann Dunham was a U.S. citizen, the birther rumors, even if true, would still be wrong about Obamaââ¬â¢s eligibility to be president. As the Harvard Law Review explained in 2015: ââ¬Å"All the sources routinely used to interpret the Constitution confirm that the phrase ââ¬Ënatural born citizenââ¬â¢ has a specific meaning: namely, someone who was a U.S. citizen at birth with no need to go through a naturalization proceeding at some later time. And Congress has made equally clear from the time of the framing of the Constitution to the current day that, subject to certain residency requirements on the parents, someone born to a U.S. citizen parent generally becomes a U.S. citizen without regard to whether the birth takes place in Canada, the Canal Zone, or the continental United States.â⬠The U.S. State Department also notes that a child born abroad to an American citizen and ââ¬Å"one alien parentâ⬠acquires U.S. citizenship at birth. The birthers have never disputed that Ann Dunham was a U.S. citizen. Their failure to do so seriously weakens their argument, not to mention the fact that Obama has provided documentation about his birthplace, a Honolulu newspaper announced his birth just days afterward and family friends said they met him as a newborn in Hawaii. These friends include former Hawaii Gov. Neil Abercrombie. Abercrombie knew both of Barack Obamas parents well. ââ¬Å"Of course, we had no idea at the time that the future president of the United States was that little boy, that little baby,â⬠Abercrombie told CNN in 2015. The former governor became emotional discussing the birther accusations. ââ¬Å"I would just like to ask people who have this political orientation towards the president, respect us here in Hawaii, respect his mother and father. Respect the people that I loved and the people that I knew and the little boy who grew up here in paradise and became president.â⬠à How the Birther Movement Began Although the birther rumors became extremely widespread, a lot of confusion exists about the origins of the movement. In fact, it has been linked to both Hillary Clinton and Donald Trump. But did either of these two, who became rivals during the 2016 presidential race, actually begin the birther movement? Donald Trumpââ¬â¢s remarks about birtherism have only added to the confusion. ââ¬Å"Hillary Clinton and her campaign in 2008 started the birther controversy,â⬠Trump saidà while campaigning for president in 2016. ââ¬Å"I finished it.â⬠In 2015, U.S. Sen. Ted Cruz (R-Texas) also blamed Hillary Clinton for the birther rumors. But both Politifact and Fact-check.org, reportedly the first website to acquire Obamaââ¬â¢s birth certificate, have found no connection between the 2008 Clinton campaign and the birther rumors, even if some of her supporters latched on to the unfounded claims. Birtherism simply canââ¬â¢t be traced to a single source, but Politico has linked it to an anonymous chain email from 2008. The email reportedly stated: ââ¬Å"Barack Obamaââ¬â¢s mother was living in Kenya with his Arab-African father late in her pregnancy. She was not allowed to travel by plane then, so Barack Obama was born there and his mother then took him to Hawaii to register his birth.â⬠Daily Beast editor John Avlon has blamed Clinton volunteer Linda Starr of Texas for spreading the email. For her part,à Clinton has adamantly denied involvement in the smear campaign. She told CNNââ¬â¢s Don Lemon that to blame her ââ¬Å"is so ludicrous, Don. You know, honestly, I just believe that, first of all, itââ¬â¢s totally untrue, and secondly, you know, the president and I have never had any kind of confrontation like that. You know, I have been blamed for nearly everything, that was a new one to me.â⬠While the name of the birther responsible for the viral email remains unknown, some birthers have proudly identified themselves with the movement. They include Jerome Corsi, whose 2008 book, ââ¬Å"Obama Nation,â⬠accused the president of maintaining dual American and Kenyan citizenship. Thereââ¬â¢s also former Pennsylvania deputy attorney general Phil Berg. ââ¬Å"Obama carries multiple citizenships and is ineligible to run for President of the United States. United States Constitution, Article II, Section 1,â⬠Berg said in a federal District court complaint filed on Aug. 21, 2008. Berg had spent the previous years suggesting that George W. Bush was somehow involved in the Sept. 11, 2001, terrorist attacks. After his lawsuit about Obamaââ¬â¢s birthplace came others. Alan Keyes, who ran against Obama in the 2004 Senate race and later for president, filed a suit in California concerning Obamaââ¬â¢s eligibility to be president. California resident Orly Taitz would file more suits. New Jersey resident Leo Donofrio filed such a suit as well. The courts have ultimatelyà dismissed all suits involving the birther claims. How Birthers Have Affected Obama In response to the birther claims, Obama has released his birth certificate, which in Hawaii is a certificate of birth. But birthers, including Donald Trump, insisted that the certificate was invalid. Hawaii state officials have even vouched for Obama, including Dr. Chiyome Fukino, then director of the Hawaiââ¬â¢i State Department of Health. The doctor swore in 2008 and 2009, ââ¬Å"I... have seen the original vital records maintained on file by the Hawaiââ¬â¢i State Department of Health verifying Barrack (sic) Hussein Obama was born in Hawaiââ¬â¢i and is a natural-born American citizen.â⬠Still, Donald Trump appeared on a number of television programs questioning the authenticity of Obamaââ¬â¢s birth certificate and suggesting that no hospital records of his birth in Hawaii could be found. His wife,à Melania Trump, made suchà claims on television as well. Spreading the birther claims earned Trump a following among Americans aggrieved that Obama was president. According to polls, more than a quarter of Americans believed Obama was not born in the United States because of the controversy. After years of declaring otherwise, Trump finally admitted that Obama was a U.S. citizen. While stumping for Hillary Clinton in September 2016, First Lady Michelle Obama called the birther claims ââ¬Å"hurtful, deceitful questions, deliberately designed to undermine [Obamaââ¬â¢s] presidency.ââ¬

2 - Assignment Example The resultant of this would be the loss of threads and finally loosening of the components. The mechanism behind this corrosion is in the difference that occurs in levels of oxygen between internal crevice and the external surface. The depletion of oxygen on the crevice causes it to be he anode creating an extremely corrosive environment inside the crevice. The corrosion occurs on the low-oxygen area acting as the anode with protection on the high oxygen area as the cathodes. Pitting is another form of localized corrosion that penetrates into metals as quickly as possible mostly at an angle of ninety degrees. As a result of it, we can have leaking tanks. This kind of corrosion is often hard to identify. The moment it is visible to humans, the damage will have been extensive the passivation layer of stainless steel makes it vulnerable pitting corrosion rather than uniform corrosion.The figure below show pits on stainless steel rings after it was subjected to the marine environment Surface corrosion occurs on the surfaces of the materials in question.it has different types that include: stainless steels involves a flat-gray uniform surface attack mostly leading to significant damages in form of deposits of corrosion. Non-stainless products do suffer an extreme corrosion under a pale-black surface. Color-anodized surfaces involves crater formation in places of heavy attacks. In normal conditions only a partial or complete loss of color intensity occurs. This kind of corrosion occurs as a result of chemical and electrochemical influences. This only happens when there is connection with excessive acid contents in relation to stainless steel, soldered connections and sintered carbide metal are concerned. In the case of stainless steel, corrosion is aided by the impact of water/humidity. On anodized surfaces, the impact of acids or

History Of Copper Essay Example | Topics and Well Written Essays - 250 words
History Of Copper - Essay Example The alloys were harder, making alloys to be extra useful and by 2500 BC, bronze was used by a large group of people, this brought up what historians called bronze era (Leskinen 2009). By 1500 A.D, copper in art started in western countries and it was inform of bronze sculptures. Some places in the East a place called Nara Buddha, a monumental sculpture in bronze dates back to 751 A.D.The next discovery was about copper plating that started in the mid-1600s.tis technique was use used in ship building, to protect the ship from storms. In the modern world there has been improvement in the modern world due to technologies that have emerged. The improvement started to change and to grow to meet the need of the society. This includes flash smelting which began in 1949 and in 1990 copper oxide was first used as a superconductor. The Bronze Age abruptly ended at around 12000 BC, this was due the interference of the international trade routes and the breakdown of the ancient world. Areas where tin was supplied dried up. Is led to the introduction of iron not because it was better than copper but because of its availability (Leskinen 2009). Antecedently, Rome started to be served with copper by copper mines in Spain and Asia and as the empire became big a lot of copper increased in the system. And Spain could produce about 15000 tons of refined copper per anum.It is known that brass an alloy of copper was first dived at this time (Leskinen 2009). This gives a report on history of

Demand vs Supply Essay Example for Free
Demand vs Supply Essay The two main driving forces of the economy are supply and demand. Understanding the basic concepts of supply and demand can help an organization focus on the bottom line. According to Gretzen (2007), demand is the relationship between price and quantity. Supply refers to the amount of a good or service available at any particular price. The principle of supply and demand describes a balance that develops between the supply of an item or service and the demand for it (Kleinman, 2009). Economics plays a major role in the health care industry. As a resource, the health care workforce is a determinant of the balance between supply and demand. The health care workforce consists of nurses, physicians, and other ancillary health care workers such as certified nursesââ¬â¢ aides (CNAââ¬â¢s) and patient care associates (PCAââ¬â¢s). The supply of health care workers directly impacts the demand of quality care rendered to patients. SERVICE OR PRODUCT Health care organizations have specific stated missions and visions to map out their fundamental way of operation. In health care, the workforce is instrumental in assisting with the organizational delivery of services to consumers (patients). The primary issue for all health care workforce personnel is that of inadequate staffing. This paper focuses on the staffing effectiveness of supplemental staffing of health care personnel within the inpatient setting. IMPACT Nursing managers formulate staffing patterns on a daily basis. The staffing of inpatient units requires a knowledge of unit census (total bed capacity),à consideration of patient acuity (level of care required for the patient), and skill mix (nursing hours per patient per day and nurse patient ratio) (U. S. Department of Health and Human Services, 2002). Often times, inadequate staffing is due to a high rate of call outs of sickness or other emergencies. Inadequate staffing directly impacts patient safety and quality of care. All health care titles render supplemental staffing coverage in one of two ways, overtime and through per-diem agencies. Overtime employment provides regular full time employees with monies set at a rate of time and half for any extra work completed over the prescribed 40 hours a week. Per-diem agencies are outside contractors capable of providing their own qualified titled personnel to fill vacancies with monies defined at a set rate. Patients are admitted to inpatient setting with varied co-morbidities may or may not indirectly increase the necessity of staff. Patients are often admitted for diagnoses of altered mental status, agitation / combativeness, risk for falls, suicidal ideation, and alcohol or drug intoxication. Many patients require a higher level of skilled care, such as turning and repositioning, and assistance with activities of daily living such as toileting and eating. It requires a higher staff to patient ratio to provide safe, effective quality care. PERSPECTIVE AND RATIONALE According to published reports there are key factors affecting the adequacy of the health care workforce. Some key factors include an aging workforce of where 40 percent of practicing physicians are older than 55, and one-third of the nursing workforce is over 50 with a majority of both professionals seeking to retire within the next 10 years (Alliance for Health Reform, 2011). The largest groups of health professionals in the United States are composed of Registered Nurses. Statistically, there is a huge decline in the numbers of nurses within all regions of the U.S. An estimated 118,000 FTE RNs will exit the workforce within the next five years (Staiger, Auerbac, Buerhaus, 2012). This potentially leaves a major void in terms of numbers of bodies needed to fill vacated positions. Low staffing levels are associated with higher rates of adverse outcomes that are directly sensitive to nursing attention, such as urinary tract infections, pneumonia, pressure ulcers, and falls (American Federation of Teachers, 2012). Unintended additional costsà associated with the development of complications in patients are greater than labor savings when units are understaffed. Acquiring pressure ulcers are estimated to cost the health care industry $8.5 billion per year (Kleinman, 2009) Overtime costs and per-diem agency costs canââ¬â¢t stand alone to solve the issues of staffing shortage. Their combined usage enables institutions to deliver optimal health care services to consumers/ patients. The supply of overtime and per-diem staff meets the increased demands of patients. It also assists in the delivery of quality care through services rendered. In terms of patient safety, the potentiality of the risk of injury to patients via falls, medication errors, and or sentinel events decreases. CONCLUSION The United States is a great consumer demand for health care services. The supply of such services is affected by varied factors. These factors directly influence the financial stability of health care organizations. Recessional times cause delays in career and retirement plans for health care professionals. In recessional times, there are noted changes in the supply and demand of the health care workforce. The shortage of registered nurses and providers in the workforce may inadvertently lead to a reduction in health care access for consumers. Inadequate staffing levels place heavy burdens on the nursing staff. Adverse events such as falls, hospital acquired infections and medication errors are potentially painful and life threatening events. Adverse events can result in considerable costs to be paid by the understaffed institution. For this reason alone, supplemental staffing via agency and overtime personnel provides a measure of increased patient safety. The future is trending towards the assistance in the recovery of the health care workforce shortage. It will rely heavily on the provisions made by the Affordable Care Act of 2010 (Alliance for health reform, 2011). Recruitment and reinvestment in health care professions especially nurses and physicians will assure sufficient supply of workforce personnel to meet the increased demands of health care economy and itsââ¬â¢ consumers( Kaiser Foundation (2012). The Joint Commission bolsters workforce infrastructure through in-service and continuing education, supporting nursing education, and the adoption of set staffing levels based onà competency and skill mix relative to patient mix and acuity (Stanton, 2012). It also supports the establishment of financial incentives for health care organizations investing in nursing and workforce services. REFERENCES Alliance for Health Reform. (April, 2011).

EUROPEAN DISEASES Essay -- essays research papers fc
The greatest adversary to the natives in the Americas was not the swords or guns of the invaders. It was the devastation brought by deadly diseases infecting an unsuspecting population that had no immunity to such diseases. The Europeans were said to be thoroughly diseased by the time Columbus set sail on his first voyage (Cowley, 1991). Through the domestication of such animals as pigs, horses, sheep, and cattle, the Europeans exposed themselves to a vast array of pathogens which continued to be spread through wars, explorations, and city-building. Thus any European who crossed the Atlantic was immune to such diseases as measles and smallpox because of battling them as a child. The original inhabitants traveled to the New World in groups of a couple hundred each. Because microbes such as the ones that cause measles and smallpox need populations of several million to survive, the original populations were unaffected by the deadly diseases. However, by the time Columbus arrived, the major Indian groups of Aztecs, Incas, and Mayas had built their populations up enough to sustain mass epidemics. Evidence shows that these populations suffered from such diseases as syphilis, tuberculosis, a few intestinal parasites, and some types of flu, but not the diseases that had been infecting the Old World for centuries. Thus when the Europeans arrived bringing diseases such as smallpox, measles, whooping cough, etc. the natives were immunologically defenseless (Cowley, 1991). It is believed that 40 million to 50 million people inhabited the New World before the arrival of Columbus and the Europeans, and that most of them died within a few decades. For example, Mexico's population fell from about 30 million in 1519 to 3 million in 1588. The other South and Central American countries as well as the Caribbean islands suffered the same devastation (Cowley, 1991). Mass epidemics were virtually unknown in the New World prior to the invasion of the Europeans. Aside from their lack of immunity to the pathogens, another factor in the rapid spread of the diseases could have been the weariness of the Indian populations. Due to their recent conquest and oppression by the Spaniards, the Indians were probably too tired to fight the infections. One thing that must be noted is that contrary to popular belief, infectious agents such as viruses, bacteria, parasites, etc. are not desig... ...o be like syphilis in that it was haunting isolated populations before becoming global. And just as syphilis was carried globally by ships; jet planes and world-wide social changes have brought AIDS out of isolation. Like smallpox and other infectious diseases in the 16th century and AIDS in the 20th century, what new disease will hit and destroy unsuspecting populations? BIBLIOGRAPHY Cowley, Geoffrey.

In addition, overwhelming historical evidence suggests that the greatest rates of morbidity and death from infection are associated with the introduction of new diseases from one region of the world to another by processes associated with civilized transport of goods at speeds and over distances outside the range of movements common to hunting and gathering groups.

Industrial Revolution facts, information Essay
Industrialisation is a period in which machines take place instead of men. It is the period in which machines do work once done by humans. This is basically time period from which the agrarian society transform into an industrial society. Background: Industrialisation took place in the mid of 18th century to early 19th century in mainly Europe and North America; starting in Great Britain followed by Germany, Belgium, and France. During this time period industries played a vital role in the urbanization of Europe. It was a shift from rural work to industrial labor. Mostly labor before industrialization used to work on their own, things were mostly handmade which took many time and labor. Industrialisation helped the poor community in different aspects of saving time as well as energy. The transformation from an agricultural economy to industrial economy is known as Industrial Revolution. Industrialisation had played the vital role in the construction of new society in Europe. As industrialization changed scenario of society but also bring devastation to the society because Capitalism emerged during industrialization which made rich community more richer and poor community poorer. Howard Zinn once said ââ¬Å"Capitalism has been always the failure for the lower classes. It is now beginning to fail for the middle classâ⬠. Such various observers as Karl Marx and Ãâ°mile Durkheim cited the ââ¬Å"alienationâ⬠and ââ¬Å"anomieâ⬠of individual workers faced by seemingly meaningless tasks and rapidly altering goals. The fragmentation of the extended family and community tended to isolate individuals and to countervail traditional values. By the very mechanism of growth, industrialism appears to create a new strain of poverty, whose victims for a variety of reasons are unable to compete according to the rules of the industrial order. In the major industrial ized nations of the late 20th century, such developments as automated technology, an expanding service sector, and increasing suburbanization signaled what some observers called the emergence of a postindustrial society. Industrialisation in Thomas Hardyââ¬â¢s novel ââ¬Å"Tess Of The Dââ¬â¢Ubbervillesâ⬠: When Thomas Hardy was born in 1840, agriculture was the most important industry in England, employing roughly 20% of the labor force. By 1900, however, agricultural workers comprised less than 10% of the total workforce. Hardy witnessed much of this hardship as a child growing up in Dorsetââ¬âwhich would later become his model for Wessex. Hardyââ¬â¢s Dorset was, in fact, the poorest and least industrialized county in Britain, and the farm laborers led difficult, often unrewarding lives. Laborers toiled from six oââ¬â¢clock in the morning until six oââ¬â¢clock at night in the summer and from the first light until dusk in the winter. It was not uncommon to find women and children in the fields; their labor was frequently used as the cheap substitute for menââ¬â¢s. Their diet was monotonous and meagerââ¬âbread, bacon and cheese, and only occasionally milk. They drank beer and tea, and those who could not afford tea would soak burnt toast in water. In addition, the li ving conditions of many of these laborers were horrendous. Many lived in squalor and did not have the money to improve their condition. In 1851, there were half a million such laborers in England. Thomas Hardyââ¬â¢s Tess of the dââ¬â¢Urbervilles (1891) contains complex and detailed interrogations of many Victorian values and of the capitalist culture of his time. This novel is a fierce condemnation of the social, ethical, moral, religious, and political values held by the majority of Hardyââ¬â¢s cultural elite contemporaries in England. The most obvious example of Hardyââ¬â¢s cultural criticism is his assertion in the novelââ¬â¢s subtitle that Tess is ââ¬Å"A Pure Woman.â⬠By traditional Victorian standards, Tess is a fallen woman and as such is considered damaged goods suitable for the lowest bidder. Hardy is radically departing from these values by proclaiming Tessââ¬â¢s purity and virtue even though she has had sexual relations outside of marriage. It is, therefore, not surprising that initial reaction to the novel was highly negative. This cultural criticism is one of Hardyââ¬â¢s many challenges to the social conventions and values of his time found within this text. Tessââ¬â¢s struggle with Alec is both a gender and a class conflict. The text uses Tessââ¬â¢s relationship with Alec to expose the similarities and interconnections between a manââ¬â¢s physical and emotional oppression of a woman, on the one hand, and a more powerful social classââ¬â¢s economic oppression and destruction of a weaker class, on the other. Hardyââ¬â¢s Tess laments the destruction of the independent rural artisan class and blames nouveaux rich capitalist society for this degradation. Hardy goes on to condemn the industrialization of agricultural work because of what he views as the extremely destructive impact of technology and mechanization upon the quality of the rural workersââ¬â¢ lives. Hardy is also extremely critical of organized Christianity in several places throughout the novel, including the scene in which S orrow is actually denied a Christian burial. Hardy also raises questions about the injustice and inequality of a legal system, which finds Alec innocent of any wrongdoing but sentences Tess to death. Hardy clearly defines Tess as a member of the independent rural artisan class, a group whose way of life as a whole he asserts is at risk of extinction and whose quality of life is in decline due to capitalist economic forces and the industrialization of agricultural labor . He writes: ââ¬Å"The village had formerly contained, side by side with the agricultural labourers, an interesting and better-informed class, ranking distinctly above the former ââ¬â the class to which Tessââ¬â¢s father and mother had belonged ââ¬â and including the carpenter, the smith, the shoemaker, the huckster, together with nondescript workers other than farm-labourers; a set of people who owed a certain stability of aim and conduct to the fact of their being life-holders like Tessââ¬â¢s father, or copyholders, or, occasionally, small free-holders. But as the long holdings fell in they were seldom again let to similar tenants, and were mostly pulled downâ⬠. (435) Hardyââ¬â¢s description of Alecââ¬â¢s family embodies all that Hardy maintains is wrong with capitalist nouveau riche society: there, money and status are more valuable and significant than people. Industrialisation in Charles Dicken novel ââ¬Å"David Copper Fieldâ⬠: Charles John Huffam Dickens was born on 7 February 1812 in Portsmouth, the second of eight children. When he was nine years old his father was imprisoned for debt and all of the family except for young Charles were sent to Marshalsea, the debtorsââ¬â¢ prison. Charles instead went to work in a blacking factory and suffered first hand the appalling conditions, loneliness, and despair. During his lifetime ââ¬â he died in June 1870 ââ¬â industrialization dramatically reshaped Britain, the population of London tripled and he saw the birth of the railways, the telegraph, and the steamship. He used his novels to bring to attention the social ills and abuses of Victorian England in such a way that the general public could relate and react to. For example, Oliver Twist attacked the workhouse system and portrayed a criminal underclass that captured the publicââ¬â¢s imagination. In David Copperfield and Great Expectations, he drew on his early experiences of the debtorsââ¬â¢ prison and the blacking factory. He exposed the brutal Yorkshire schools in Nicholas Nickleby and the inadequacies of the law in Pickwick Papers and Bleak House. The main reasons, therefore, were the mostly bad living conditions of the lower classes in factory cities, the automation of industry and the huge birth surplus in the country all throughout Great Britain. Furthermore, there were waves of migration into the huge cities and more and more capitalists that could be found in parliament, widely supporting political industrialization, completely neglecting the working conditions of their employees. In the Early Victorian Social Novel (1830 ââ¬â 1850), the industrial system was to blame for the bad living conditions of the workers. However, it was not considered an abstract but rather manifested itself in individuals, like good and bad factory owners, responsible and irresponsible ones. And there was an unshakeable belief in morality and that those who were bad could be converted to good ones, those who were irresponsible could be made responsible. The authors at that time drew less attention to the details of the world of work and its machines, but rather preferred the depiction of physically and mentally injured people, because of their work. Therefore many metaphors were used to describe the prevailing social conditions, such as ââ¬Å"Jungle of Workâ⬠, ââ¬Å"Prison of Workâ⬠or ââ¬Å"Subjugation of the worker through the machineâ⬠. Thinking of ââ¬Å"Social Criticismâ⬠, huge institutions in society, like workhouses, industrialized cities or even certain governmental systems might occur to oneââ¬â¢s mind in the first place. But many people forget that the smallest ââ¬Å"institutionâ⬠in society is the family. And the first socio-critical element in ââ¬Å"David Copperfieldâ⬠to begin with shall be the family itself. Therefore one has to know that families in the 19th century, especially in higher social classes, were organized completely differently than families are today. Usually, the husband was the ââ¬Å"big bossâ⬠in the house, whereas the woman had to be the ââ¬Å"good housewife and motherâ⬠who had to obey her husband. And the children, above all boys, normally were educated very strictly, and once out of the age in which they had to be cared for by their mother, they were completely under their fatherââ¬â¢s control and influence. Dickensââ¬â¢ now wants to criticize th is more or less ââ¬Å"old-fashioned positionâ⬠in his novel, but therefore he has to set up the right situation. The orphanage was an important topic at the time of industrialism because many parents had to work very hard and there were bad working conditions in the factories or workhouses. Subsequently, the parents were often physically worn out, many mothers not rarely died during or shortly after the birth of their children, and many fathers often died during their difficult, inhuman and most dangerous work. And the children they left were orphans, many of them still too young to care for themselves and facing a world they were not ready for, yet. And this topic of the orphanage is also raised in David Copperfield. As already Davidââ¬â¢s father is dead yet and his mother dies shortly after the birth of her second child, presumably suffering from the tortures of her cruel husband. Dickens was not the first novelist to draw the attention of the reading public to the deprivation of the lower classes in England, but he was much more successful than his predecessors in exposing the ills of the industrial society including class division, poverty, bad sanitation, privilege and meritocracy and the experience of the metropolis. In common with many nineteenth-century authors, Dickens used the novel as a repository of social conscience. The novel directs this ironical attack at the Victorian public opinion, which was either unaware or condoned such treatment of poor children. Dickens was critical about the Victorian education system, which is reflected not only in Nicholas Nickleby, Hard Times and Our Mutual Friend but also in his journalism and public speeches. As a boy, he was shocked to read reports about the cheap boarding schools in the North. In Nicholas Nickleby Dickens describes abusive practices in Yorkshire boarding schools. However, Dickens does not only criticise the malicious education system, but he is primarily concerned with the fates of these unfortunate children who are representatives of the most vulnerable portion of the society.

Communication Process Paper Essay Example
Communication Process Paper Essay Example Communication Process Paper Essay Communication Process Paper Essay Communication is important within all organizations, therefore an organizations communication process may be unique to that organization. Discussion includes the communication climate of Upshaw Processing as a whole. In addition, discussion includes the strengths and weaknesses of Upshawââ¬â¢s communication. Discussion includes the contributions of management, supervisors, and employees that include an effective communication process. In addition, discussion includes an example that supports the communication process. Communication Climate The communication climate in Upshaw Processing may be formal or informal, depending on the employees working. Upshaw Processing is a small family business; therefore, most of the employees are family members except during deer season when non-family employees work. The use of informal channels of communication occurs during off-season when workers include family members, whereas during deer season, formal channels of communication occur when workers include non-family members. Formal channels are established by the organization and transmit messages that are related to the professional activities of the membersâ⬠(Robbins Judge, 2009, p. 353). ââ¬Å"Informal channels are spontaneous and emerge as a response to individual choicesâ⬠(Robbins Judge, 2009, p. 353). Strengths of Communication The communication at Upshaw Processing may reach a high level of success before and during deer season. During deer season many customers visit the processing business, therefore communication is important for the success of the business. Lack of communication during deer season may cause confusion with the customers, employees, and owners. Communication is important because during deer season the activity increases to a high level. Employees are helping customers who are dropping off a deer for processing, employees are helping customers who are picking up a deer, and employees are helping to process other deer. The use of formal channel communication is important during deer season because of the high level of activity, otherwise a customer may pick up the wrong deer. Weaknesses of Communication Although communication levels are strong at Upshaw Processing, at times a weakness in communication may appear. Noise may cause a weakness in communication, whereas the employee may not understand the instructions from the supervisor. The weakness in communication may cause the loss of customers and money for the business. By using the Wheel of formal communication, Upshaw Processing weeds out the weaknesses in communication, otherwise the success of the business would be at risk. By weeding out the weakness in communication, the owners of Upshaw Processing are guaranteeing the success of the business. Effective Communication Of the Three Common Small-Group Networks, the use of the Wheel works for the processing business, therefore the owner relays messages to all employees. The use of the Wheel Network insures that all employees receive and understand the message from the start. Communication during the off-season is successful because employees are family members and know the job details for success. Long time employees learn to read the nonverbal actions of the owners and other employees, therefore spoken words may not occur for the communication to be successful. Example of Support An example of support for the communication climate within the processing business; employees are working and a customer comes in to pick up a deer, a certain employee will wash and wait on the customer. The employee returns to the owner to see what tub number holds the customers deer, and then retrieves the deer from the freezer. The employee collects the money for the processing fee and hands the money to the owner. The owner instructs a certain employee on the conduction of the collection process, therefore the action of communication of collection is successful. In addition to the above example, the owners instruct skinning room employees on the deer skinning process. Clear communication is important in the deer skinning process for the safety of the employees. Deer skinning involves the use of sharp knives, therefore an employee must understand the deer skinning process to work that area of the business. Conclusion The success of an organization requires communication, whereas each organization may practice a different type of communication process. Discussion includes information concerning the communication climate at Upshaw Processing. In addition, discussion includes the strengths and weaknesses of communication within Upshaw Processing. Discussion includes the effective communication process of the supervisor, manager, and employees. In conclusion, discussion includes an example that supports the communication process.

Battle of Blore Heath - War of the Roses
Battle of Blore Heath - War of the Roses Battle of Blore Heath - Conflict Date: The Battle of Blore Heath was fought September 23, 1459, during the Wars of the Roses (1455-1485). Armies Commanders: Lancastrian James Touchet, Baron AudleyJohn Sutton, Baron Dudley8,000-14,000 men Yorkists Richard Neville, Earl of Salisbury3,000-5,000 men Battle of Blore Heath - Background: Open fighting between the Lancastrian forces of King Henry VI and the Richard, Duke of York began in 1455 at the First Battle of St. Albans. A Yorkist victory, the battle was a relatively minor engagement and Richard did not attempt to usurp the throne. In the four years that followed, an uneasy peace settled over the two sides and no fighting occurred. By 1459, tensions had again risen and both sides actively began recruiting forces. Establishing himself at Ludlow Castle in Shropshire, Richard began summoning troops for action against the king. These efforts were countered by the Queen, Margaret of Anjou who was raising men in support of her husband. Learning that Richard Neville, Earl of Salisbury was moving south from Middleham Castle in Yorkshire to join Richard, she dispatched a newly raised force under James Touchet, Baron Audley to intercept the Yorkists. Marching out, Audley intended to set an ambush for Salisbury at Blore Heath near Market Drayton. Moving onto the barren heathland on September 23, he formed his 8,000-14,000 men behind a great hedge facing northeast towards Newcastle-under-Lyme. Battle of Blore Heath - Deployments: As the Yorkists approached later that day, their scouts spotted the Lancastrian banners which protruded over the top of the hedge. Alerted to the enemys presence, Salisbury formed his 3,000-5,000 men for battle with his left anchored on a wood and his right on his wagon train which had been circled. Outnumbered, he intended to fight a defensive battle. The two forces were separated by Hempmill Brook which ran across the battlefield. Wide with steep sides and a strong current, the stream was a significant obstruction for both forces. Battle of Blore Heath - Fighting Begins: The fighting opened with fire from the opposing armies archers. Due to the distance separating the forces, this proved largely ineffectual. Realizing that any attack on Audleys larger army was doomed to fail, Salisbury sought to lure the Lancastrians out of their position. To accomplish this, he began a feigned retreat of his center. Seeing this, a force of Lancastrian cavalry charged forward, possibly without orders. Having accomplished his goal, Salisbury returned his men to their lines and met the enemy assault. Battle of Blore Heath - Yorkist Victory: Striking the Lancastrians as they crossed the stream, they repelled the attack and inflicted heavy losses. Withdrawing to their lines, the Lancastrians reformed. Now committed to the offensive, Audley led a second assault forward. This achieved greater success and the bulk of his men crossed the stream and engaged the Yorkists. In a period of brutal fighting, Audley was struck down. With his death, John Sutton, Baron Dudley, took command and led forward an additional 4,000 infantry. Like the others, this attack proved unsuccessful. As the fighting swung in the favor of the Yorkists, around 500 Lancastrians deserted to the enemy. With Audley dead and their lines wavering, the Lancastrian army broke from the field in a rout. Fleeing the heath, they were pursued by Salisburys men as far as the River Tern (two miles away) where additional casualties were inflicted. Battle of Blore Heath - Aftermath: The Battle of Blore Heath cost the Lancastrians around 2,000 killed, while the Yorkists incurred around 1,000. Having defeated Audley, Salisbury camped at Market Drayton before pressing on to Ludlow Castle. Concerned about Lancastrian forces in the area, he paid a local friar to fire a on cannon the battlefield through the night to convince them that the battle was ongoing. Though a decisive battlefield victory for the Yorkists, the triumph at Blore Heath was soon undercut by Richards defeat at Ludford Bridge on October 12. Bested by the king, Richard and his sons were forced to flee the country. Selected Sources UK Battlefields Resource Centre: Battle of Blore HeathWars of the Roses: Blore Heath

Archaeology - Neanderthals and Modern Humans Essay
Archaeology - Neanderthals and Modern Humans - Essay Example Human kind is very clever in this regard as well as in the regard of preserving life in severe environments, for a period of time. Yet, he states that human kind has often driven species to extinction and I have to personally agree with his position on this topic. Human kind is known to abuse the environment around it and this is no different from then as now. This is the main reason why so many living biological organisms are either extinct now or on the verge of extinction. Human kind over does it in practically every aspect of living so therefore my opinion is not very different from Wright's. Wright's belief is that it is this mentality of human kind that has ultimately lead to the downfall of many ancient civilizations. His point is that human kind falls into progress traps. We develop things that create a negative impact in our environments and that negatively affect our very own existence, thereby driving our own species into extinction. Wright also claims that cultural phenomena have absolutely nothing to do with human evolution and again I tend to agree with this. One of the examples that he gives in his book, in regards to the problem solving skills of mankind, is indicative in the summary he does of the Samarian

X-ray crystallography Research Paper Example | Topics and Well Written Essays - 1000 words
X-ray crystallography - Research Paper Example With this diffraction, it I easy to derive the three-dimensional outline or image projection of the density of electrons as profiled in the crystal. The crystal creates a platform for developing a pattern for mean positions of the atoms in the crystal. One can also manage to determine the chemical bonds of the structure, say carbon in diamond crystals and the varying disorders of some of the crystalline structures. Carbon is common in crystal formation. X-ray crystallography has been applied in many scientific fields due to the presence of crystals of many chemical compounds and elements. A pure crystalline structure is that of table salt, scientifically known as sodium chloride and represented by the chemical formula NaCl. Crystalline structures that have been studied by X-ray crystallography are many. Some of them are calcium fluoride (CaF2), calcite (CaCO3) and pyrite (FeS2). Others are spinel (MgAl2O4) and brucite (MgO4) among others. The inclusion of X-rays in studying crystalline structures enabled further understanding of these compounds in a manner that had never been used before and allowed for formation of more complex compounds through chemical reactions caused by interaction of crystalline structures. X-ray crystallography can be used to identify and locate unusual electronic properties of a material by studying their electron positions and mobility. It is also a tool for noting elastic properties of a material considering the chemical interactions that occur within the crystal and the associated processes. With these properties, X-ray crystallography is used in the design and manufacture of pharmaceuticals. Their application involves combining elements and modifying their crystalline structures to ensure that they bond as required (Clegg, 1988). Other than X-ray crystallography, there are other methods associated with determining atomic structures (Rhodes, 2006). However, they all rely on the principle of diffraction. These
