Biology Virus Essay

Biology Virus Essay A virus is a microorganism that cannot reproduce without a host. As a result of this, there has been a lot of controversy on whether or not a virus is a living or non-living organism. The dictionary. com definition for life is, â€Å"the condition that distinguishes organisms from inorganic objects and dead organisms, being manifested by growth through metabolism, reproduction, and the power of adaptation to environment through changes originating internally. Viruses have characteristics of both living and non-living organisms, for example, a living characteristic includes reproduction. A non-living characteristic of a virus is that they cannot have both DNA and RNA. The living characteristics of viruses state that viruses can reproduce, but viruses can only reproduce with the help of a host. As a result of viruses not being able to replicate on their own, viruses are not living organisms. Viruses are small infectious particles that have nucleic acid. They can come in many different shapes and sizes. Although viruses vary in shape the common virus has four main parts, the head, DNA or RNA, tail sheath, and tail fiber. The head of a virus is a protein shell that protects the DNA inside it also known as the genome. In comparison, viruses and living organisms both are made up of smaller units that form up to make something larger. The physical appearance of a virus and living organisms are different and what a virus is made up of is different in comparison to a living organism. Viruses are made up of proteins and nucleic acid. The protein comes together to form an encasing shell for the nucleic acid. The protein shell is called a capsid. The nucleic acid inside a capsid can either be DNA or RNA, but never both. Viruses can be classified depending on the features they have, for example the various shapes of a capsid can determine the type of virus. A capsid can be a simple or complex structure. The most complex capsid is found in bacteria called bacteriophages. A virus can also have a viral envelope which contains protein and lipids. Based on shape and structure viruses can infect bacteria, animals and plants. The way in which viruses can infect theses organisms is different. The viruses that infect bacteria are the most common. The life cycle of viruses that infect bacteria are put into two categories known as the lysogenic and lytic cycles. In the lytic cycle, the virus injects its DNA or RNA into the bacteria and makes the bacteria create all the different components that form an entire virus. These parts come together to create individual viruses and as a result of this mass production of individual viruses, the cell bursts. Viruses that go through the lytic cycle are called virulent phages. Phages that go through the lysogenic cycle are known as temperate phages. In the lysogenic cycle the virus injects its DNA or RNA into the host in the same way as the lytic cycle does except the injected DNA or RNA sits and stays inside the host. As a result the virus doesn’t create more individual viruses and the host’s cell doesn’t burst. Although the nucleic acid sits and stays inside the genome, a reaction could occur and the virus could go from the lysogenic to the lytic cycle. In conclusion, viruses have characteristics of both living and non-living organisms. Like non-living organisms, viruses can’t have both DNA and RNA. They can reproduce like living organisms but that is with the help of a host. Without the help of a host viruses can’t perform the characteristics of a living organism. Due to the lack of living characteristics, this shows that viruses are not living organisms.

The Vikings Capture and Use of Slaves

The Vikings have always been discussed throughout history as vicious people. The Viking Age lasted from the late eighth to eleventh centuries. The ancestors of the Vikings, called the Scandinavian people, traded with the Romans. Scandinavia was made up of five modern day European countries: Denmark, Norway, Finland, Iceland, and Sweden. 1 Some items that they traded included ivory, amber, skins, and furs. After the Roman Empire fell, the Scandinavian people living in Scandinavia became closer and stronger. Around the mid seventh century, the Scandinavian people used ships with sails and built large towns.At the end of the eighth century, the Scandinavian people began raiding parts of pre-modern Europe. During this time, the Scandinavian people began to be known as the Vikings. Most people in pre-modern Europe were afraid of the Viking’s raiding of their society, but the Vikings were really just seeking goods that they could trade for money. The Vikings were known as a range of different people including warriors, pirates, explorers, and merchants. The Vikings started in Scandinavia, but because of increase in population and limited land, they traveled all through Europe looking for new land to expand.But the question is, with these vicious people just raiding to look for goods to trade with and with limited land space, why did they capture slaves and how did they use and treat these slaves in their society? As you may know, the Vikings went from society to society in pre-modern Europe looking for goods including gold, jewelry, and livestock. However, the Vikings also captured children men and women from these societies and used them as slaves. Because of their limited land space, they traded most of these slaves for money. The Vikings got a majority of their slaves from Ireland.They began to get involved with a slave trade in Ireland. Slavery existed way before the Vikings came. Slaves made up a large population of trade for the Vikings. Once captured, m ost of the slaves were sold on the slave trade while others were sent to Scandinavia to become slaves of the Vikings. It has also been recorded that some laves captured from Ireland were sacrificed to heathen gods. The first attack in Ireland was in 795, and attacked approximately once a year for the next thirty to forty years. The Vikings heard of the riches that the Irish held and thought that this region would be the perfect place for the Viking people.During this attack, the Vikings mainly just raided the societies and only took some slaves, but continued to capture more slaves as time went on. For those whose fate it was to be in the trade were either sent to Iceland, Viking colonies in Britain, Islamic empires, or Byzantine empires. The Islamic and Byzantine empires contained luxury items that the Vikings wanted for the trade of slaves. These items included Byzantine silk and Arabic coins. The Vikings then used the silk and coins in trade for items from North Europe including more slaves and furs.Once these slaves were traded, they were usually required to do laborious work of the household. The treatment of these sold slaves varied from owner to owner. Some were treaded kindly while others were treated worse than livestock. Even though a majority of the captured slaves were sent to the slave trade, some of the slaves were sent back to Scandinavia to become slaves of the Vikings. The reason that all of these slaves did not go straight to Scandinavia was because of the over population in that area. If all of the slaves were used in this area, than more strain would be on the land and on the resources that it produces.The Viking society had a social class system. This caste system was separated into three classes. The highest class was called the jarls. This class was known as the noble class, the rich people of the Vikings. They were measured by their mass wealth in terms of followers, treasures, ships, and estates. They lived in fine halls and led refine d lives with countless activities. The power of each jarl depends on how many followers he has. The jarl, however, must take care of his followers. The first born of a jarl was also to become a jarl. The middle class in this system was called the karls.These people were free and owned land. They were considered the plain folks in the Viking society. They could include farmers and blacksmiths. The families of the karls usually lived in cluster homes that had their barns or workshops in the cluster. A karl could become a jarl if he gained enough fame and wealth. The lowest class in this system was called the praell. This class included slaves and bondsmen. If a man owed another man money and could not pay his debt back, he was to work for another man until his debt was paid. This would make him a bondsman, or basically a temporary slave.Also, the system’s laws stated that if a man was convicted as a theft, he could be handed over as a slave of whom he stole from. A slave could be freed, but would still be considered in the lowest caste system. The slaves at the bottom of this caste system were chattel. They hardly had any rights. They could not inherit anything or leave nothing after their death. They could not participate in any business transaction. The only relation a slave had with society was through his master. There were some branches of the culture that slaves were not allowed to take part in. These privileges of citizenship include military and jury services.Basically, a slave could not participate in these two services because they are institutions of free men in the Viking society. When a slave was no longer capable of work, due to old age disease or injury, they were put to death. The slaves of the Vikings did however have limited rights. They could accumulate property and save enough money to buy their freedom. Slaves could also marry. Even with these few rights, slaves were still considered to the Vikings as unreliable cowards who were stupi d and foul. The Vikings were polytheists. This means that they followed many gods. The father of the gods was Odin, the god of wisdom.Because of their religion and how the Vikings followed the gods, their slaves were expected to follow the same life and tasks deemed by the gods. Challenging this could mean death of the slave. A master could kill a slave and not be held accountable for it. The slaves of the Vikings had a variety of jobs that they did in the Viking society. Some of their daily work included things such as carrying loads of firewood, tending to the fields, feeding pigs and other farm animals, cutting peat, building fences, fertilizing crops, and making ropes. All of their tasks were mainly the tasks that their masters didn’t want to do.It was necessary for running a farm to have slaves working it. Slaves were used on both small and large farms. The plantation farm was not practiced with the Vikings. Slaves worked on family farms with hired help, but the slaves d id the harder work than the hired help. The women slaves that the Vikings captured who were young and beautiful were kept as servants, sexual trophies, or wives. Others were used, upon the death of their master, as a sacrifice. Female slaves were forced to have sexual advances their masters would place upon them. Slaves were allowed to form family unites, meaning having a wife and children.However, there was no religious ceremony or wedding that slaves could take part in. they were forced to content themselves with unions that did not have the approval of the church. Children born to female slaves became property of her master and a slave, but are born with some rights. However, there was not allowed to be any sexual relations or legal marriage between a free person and a slave. There was no penalty of a freeman having sexual relations with a slave. Also, a free man was allowed to marry a former slave, meaning that a free Viking could make a women slave his legal wife by giving her freedom.Illegitimate children were abundant in the slave population of the Vikings. A child born to a slave women and a free man can claim his freedom at birth only if the free father will adopt him. Once adopted, that child could be the heir of the father’s estate. When thinking of the Vikings and how they are discussed in history, people would not think that they were mainly traders. The Vikings have always been thought of as mean and vicious people that destroyed everything in their path. All that the Vikings wanted were riches. They traded many different kinds of goods including slaves. 4 The Vikings captured their slaves form Europe, mostly from Ireland. The slaves they traded were mainly sent to the Islamic and Byzantine empires. No one would think that the Vikings would be trading slaves for luxury items like gold, jewelry, and livestock. Not all of the slaves captured were sold, however. Due to the limited living space, only small portions of these captured slaves wer e sent back to Scandinavia. There is a caste system in the Viking society with three different classes, with slaves in the lowest class. The slaves that were sent to work for the Vikings were treated better than other slaves around the world.Yes, they had long hard jobs that their masters did not want to do, but they did have a few rights and opportunities of freedom. Male slaves were meant to tend to the fields and livestock while female slaves were used as sex trophies or wives. 17 Slaves were expected to listen to their masters and follow the lifestyle of their master’s religion. 19 The slaves of the Vikings were even allowed to form family units and have children, but could not have a formal marriage ceremony. 17 Slavery impacted the Viking society not only by aiding their masters in Scandinavia, but also by aiding the Vikings in trade with other societies.

Equality Essay Example | Topics and Well Written Essays - 750 words - 1

Equality - Essay Example While there are notions that connect equality with the similarity and sameness of identity, they identify equality with similarity, rather than sameness. However, probing further, the concept of equality is distinguished from the definition of identity, as two identical things may not be equal......(Gospath, 2007) In addition, the Marxist definitions have simplified the concept of equality as being a system of relations where every one has equal rights, privileges, and status. As per this theory, the concept of equality has been the result of development of concepts related to freedom and universality. It has cited the equality definition being not true in many societies of the world, like Afghanistan where the gender equality is still not present, as females are not treated at par with the male members of these tribal societies. The Marxist theory further propounds that due to the amassing of wealth by a miniscule percentage of the society, inequality was more evident than equality. Similarly, as per this theory, the religious equality was seen more in the form of inequality as the priests and other Godmen had more privileges and rights than the general masses....(Eq) Both of these cannot co-exist. It is often seen that with different levels of power and wealth accumulation, the real justice is not possible, as more powerful will always try to exploit the weaker section of the society. As per Friedrich Nietzsche, (Human, All Too Human, #92), justice is a trade, which has originated among those who are equally powerful. While he maintains that justice is just the payment and exchange within the characteristic of trade, everyone gives what the other person wants and each gets what he wants in return. It has been emphasized several times that fairness, being a form of justice, is possible, maybe rarely only, among equally powerful people only. Hence, justice cannot be treated at par with equality, as the basic character of justice is to trade on reasonably

Is Taiwan a Country Research Paper Example | Topics and Well Written Essays - 4000 words

Is Taiwan a Country - Research Paper Example Taiwan Island is separated from mainland China by the Taiwan Strait and borders the South China Sea and the Philippine Sea to the south, the East China Sea in the north, and the Pacific Ocean in the west (Wikipedia, 2006a). The perennial debate over â€Å"independence† versus â€Å"unification† in Taiwan is a case in point. This paper discusses some facts with respect to the question of whether Taiwan is an independent country or not. Though Taiwan has a distinct boundary of its own, the United States and most other significant nations recognize one China and thus include the boundaries of Taiwan as being part of the boundaries of China (Rosenberg, 2006b) Taiwan is home to almost 23 million people, making it the 48th largest "county" in the world, with a population slightly smaller than North Korea but larger than Romania (Rosenberg, 2006b). Over the past few decades, the average age of Taiwan’s population has increased by 1.8 percent. The population is one of the criteria for an independent country and since people live in Taiwan on an ongoing basis satisfies this criterion. Education is compulsory and Taiwan has more than 150 institutions of higher learning. Taiwan is home to the Palace Museum, which houses over 650,000 pieces of Chinese bronze, jade, calligraphy, painting, and porcelain. In the past few decades, Taiwan is recognized as a growing economy. It has become one of the newly industrialized countries (NICs). In 1983 the GNP of the country approached US$50 billion and its per capita income reached US$2,444. Taiwan is one of the top 15 trading nations. Taiwan has gained in terms of its economy but has substantially waned in terms of its international status (Weng, 1984). Besides, Taiwan is an economic powerhouse - its one of the four economic tigers of Southeast Asia (They have included South Korea, Taiwan, Singapore, and Hong Kong.). Its GDP per capita is among the top 30 of the world.

Environmental Geology Assignment Example | Topics and Well Written Essays - 500 words

Environmental Geology - Assignment Example The Disaster yielded both to economic and life loss where fifty-seven people died besides obliteration of 250 homes and the region’s infrastructure. Additionally, the mountain also comprises of crater glacier that has an ice thickness raging amid 1 to 2 meters, thus making it young geologically. The mountain besides having glaciated valleys during eruption incidences, it comprises of three rivers namely Toutle, Kalama and Lewis where their purposes entail recreational and power generation (Samson 17). For illustration, lewis, which feeds three dams mainly for hydropower production, is helpful to the park itself and society. The park has its contribution regarding environmental degradation setbacks that have affected the area besides humanity and wildlife. The frequent eruption incidences witnessed on the mountain comprises production of obnoxious gases like Chlorine and HFCs that contribute to the destruction of ozone (GVP). However, this feature to numerous populaces may not be clear, but scientifically it is evident that volcano eruptions normally comprise of harmful gases that enhance global warming. This is due to the obliteration of the ozone layer that is liable for filtration of harmful solar rays to human. The eruptions besides destroying the surrounding forest cover, it also yields to wildlife destruction that adorns the mountain. The destruction inevitable because no known human efforts or any known remedy can salvage both the forest and wildlife. According to some concerns emanating from environmentalists, they stated that, the augmenting volcanic ash might yield to prolonged negative impacts like freezing, crop destruction or horrific hazards (GVP). This is an indication that, in the future these occurrences may render the region unfruitful because the economic factors that mark the place mighty become extinct. Its eruption yields to burning of numerous insects hence destroying ecosystem that

Apologetics Essay Example | Topics and Well Written Essays - 500 words - 1

Apologetics - Essay Example On the other hand there have been apologetics that believe in religious pluralism and attempt to spread the message that all religions lead to the same god. This paper examines the statement of the apologetics and discusses what such statements mean. Hutchison (2003) asserts that religious pluralism is a type of interfaith dialogue that is conducted between people with from different religions to bring down tensions and conflicts in their religions. The concept gives rise to statements such as All Religions lead to the same God or that many paths lead to the one God and so on. Religions such as Hinduism, Sikhism, Buddhism and others practice ‘universalism’ with a ‘Inclusivism’ mindset where gods from other religions are tolerated, accepted and members of other religions can be allowed to stay in peace. On the other hand, religions such as Islam, Christianity and other practice ‘Particularism’ with a ‘exclusivist’ mindset. These religions are not ready to accept other religions and call followers of other religions as pagans, heathens, infidels, unbelievers and so on and may take up crusades like Christians and Jihads like Muslims. Hutchison (2003) argues that religious pluralism is a much better way of resolving religious and sometime political conflicts and he endorses the belief that all religions lead to the same god. If the arguments for or against a particular god were limited to only theological discussions and arguments, then no harm would be done. However, religions hold much greater control over politics and passions of people an religious intolerance and issues are used as the flash point and reasons to settle other scores. The moot question is why does one believe in a particular religion and god and what does a person ask for when he is fervently offering prayers. Does the person pray to god to find a solution to his own financial and personal problems or does he pray that the neighbor also face the same problems? In a

Commerce paper essay Example | Topics and Well Written Essays - 2000 words

Commerce paper - Essay Example In addition, the CEO needs to encourage employees to openly express their views and suggestions regarding the ethical culture of the organization so as to ensure a comprehensive ethical framework. The essential elements needed for the establishment of an effective ethical framework may vary from culture to culture as ethics is related to perceptions of people. Therefore, the CEO must acquire thorough knowledge regarding different cultural aspects of the region in which his company operates. For this, the CEO has to directly or indirectly analyze the traditional beliefs and practices and living standards of people who reside in the company’s target business territory. Before setting the ethical standards of an organization, the CEO should evaluate what his competitors do and to what extent they are effective. It is clear that finance is an essential component in the design and implementation of proposed ethical standards. Here, the CEO has the responsibility to find potential s ources of finance and distribute them among different divisions of the organization. Hence, the CEO needs to choose appropriate means of market survey to understand what people expect from the company. Similarly, the CEO has to convince personnel about the significance of ethical culture since effective employee participation is inevitable for the successful implementation of the designed ethical standards. Therefore, the CEO must also ensure that the proposed ethical framework does not hurt the employees’ worksite interests. In order for setting up ethical standards effectively, upward and downward flow of communication is necessary at various management levels. Ethical standards and practices would not benefit an organization if bad behavior of managerial persons or other employees goes unreported. Hence, the CEO must design a well structured reporting system by focusing on various departmental divisions. Furthermore, the CEO has to remember the fact that generational diffe rences can raise ethical changes and hence he should not focus too much on traditional ethical practices of the organization. Gable highlights the point that people with different work styles can demonstrate same commitment and work efficacy. Hence, individuality of people has to be admired while framing ethical standards of an organization. In other words, the ethical standards must make the employees feel that the company is loyal to them. In sum, the CEO must ensure that the proposed ethical standards are authentic and not too liberal. 2. In macroeconomics and management, vertical integration is a process through which several phases in production and/or distribution of a product/service are owned and operated by a single company in order to increase business territory and market power. A vertical integration strategy has the following advantages and disadvantages; Advantages Improved supply chain coordination is the most notable benefit of a vertical integration strategy as this feature assists an organization to increase its operational efficiency and thereby profitability. In most times, it seems that a vertical integration results in closer geographic proximity and it is beneficial for the integrated firm to take advantages of reduced transportation costs. Economists opine that vertical amalgamation is useful for

Wright Brothers patent cases and influence on aviation Term Paper

Wright Brothers patent cases and influence on aviation - Term Paper Example This was way back in 1903 and two years later they created the aircraft which was the first empirically done-wing aircraft. Even though they might not be considered the first to develop a flying experimental airplane, they are credited for being the pioneers in inventing an aircraft that could be controlled with a fixed wing energized aircraft (John, 2004). Their essential success was in the construction of the three-axis control that helped the pilot to maneuver the airplane successfully and to sustain the balance it needed. This mechanism came to be the norm and is still the benchmark on fixed wing airplane of all types (John, 2004). From the start of their aviation creativity, the two brothers put their efforts into solving the puzzle of flying. Besides, they made attempts to patent their invention to prevent imitators who would outdo them in the long-run. From their invention, there was a great influence on the aviation industry that brought about the current modern airplanes. .. . However, some authors argue that the Wright Patent cases had a very retrogressive impact on the American aviation during the early nineteenth century (Parish, 2004). However, the precedents set in these cases perceived in the context of the disparity in the opinions of the military amongst the different aircrafts producer; it seems valuable to the current time period. The connection between the training pilots and the producing firms was to a large extent solidified by the social relations. The Wright Brothers’ patent case was complicated by the various technological details which involved use of diagrams that necessitated the readers and users to see the finer details under its description. The main details were well understood by the users. Fundamentally, the patent cases placed the American aviation industry on a slow growth. The American aviation had all the rights to be first ones to invent a flying machine. This was not possible under the Wright Brothers’ patent t actic. This eventually impeded the growth of the aviation industry in America. Turning the attention to the United States military aviation, the Wright brothers’ patent case had significant influence on aspects such as politics, technology, culture and the entire organization where their evolution was stunted immensely. Lack of funding by the federal government was another drawback to the military aviation owing to the patent cases which disrupted the civilian opinion on the aeronautic constituency. The various ligation cases by the Wright Brothers disrupted the development of technology in the American aviation industry and reduced the pace of the manufacturing capacity of the American aviation industry. Even though the experience of war assisted in

The mechanisms that underlay the repairs of DNA damages Thesis

The mechanisms that underlay the repairs of DNA damages - Thesis Example Cytarabine is used in the treatment of acute cases of lymphomas and leukemia. The key mutants to be acted upon are deoxyribonucleoside kinase and deoxycytidine kinase. Using S. pombe provides a greater advantage as it can be easily manipulated both physically and genetically. It also helps to understand the DNA repair mechanism in higher eukaryotes. In its natural form, yeasts do not contain a particular transporter and the particular kinase used to phosphorylate nucleoside analogues. Therefore, in this project, the S. pombe in use is adapted in that it contains deoxynucleotide kinase (dmdHK) which is found in Drosophila melanogaster (fruit fly) and is important for their phosphorylation (the addition of a phosphate molecule on to a protein molecule or any other organic molecule). It also contains the human membrane transporter (hENTI) which allows the nucleoside analogue to directly interfere with the processes taking place within the cell. 2.1.0 Material used in the practical 2.1.1 S. pombe strains The S.pombe strains used in this practical are listed below: WT: h+ ura4-D18::adhdmdNK-NAT-adhhENT1 URA4aim Swi10: (h+ ura4-D18::adhdmdNK-NAT-adhhENT1 swi10::KanMX URA4aim) Removal of damage in nucleotide excision repair. exo1: (h+ ura4-D18::adhdmdNK-NAT-adhhENT1 exo1::URA) Removal of damage in mismatch repair. rhp14: (h+ ura4-D18::adhdmdNK-NAT-adhhENT1 rhp14:: KanMX URA4aim). Recognition of damage in the process of nucleotide excision repair. rad50: (h+ ura4-D18::adhdmdNK-NAT-adhhENT1 rad50:: KanMX URA4aim) of the MRN(Mre11,Rad50,Nbs1) complex, for repair of double strand breaks. rad32D65N: (h+ ura4-D18::adhdmdNK-NAT-adhhENT1 rad32D65N URA4aim). Mre11 nuclease dead, lacks the activity of Mre11 in double strand breaks repair. 2.1.2 Medias Liquid 2.1.2.1 EMM+Glut {(EMM broth without nitrogen 109.2 g + Glutamic acid 15g) liquid + Granulated agar 10g} solid . 2.1.3: Preparing Agarose gel: first PCR Procedure: 1. With the use tape, seal all the borders of a dry and cle an glass plate. This is important for forming mold. 2. Prepare 50ml 10X TBE (Tris-boric acid-EDTA) buffer for the preparation of the gel. 3. Add 0.8% of powdered Agarose to the TBE (Tris-boric acid-EDTA) buffer in an Erlenmeyer flask. The buffer should occupy less than 50% of the total flask volume. 4. Heat the solution in a water bath or a microwave oven to facilitate the dissolving of all the Agarose grains. During the heating process, part of the buffer will evaporate. As such it is important to add more buffer solution in order to return the solution to the original volume. 5. After heating, cool the solution to 60Â °C and immerse the solution in an ethidium bromide solution once the gel solidifies. Ethidium bromide helps to intercalate DNA thus making it visible under ultra violet light. 6. Place the comb 1.0 mm above the place consequently allowing for the formation of a complete well once the Agarose solidifies. It is important to avoid air bubbles that may form between or u nder the teeth of the comb. Seal the plate with small quantities of the Agarose solution through a Pasteur pipette. Once the plate is sealed, transfer the gel in to the glass plate. It is important to swirl the gel in the flask to ensure uniformity in the temperature before pouring it out into the plate to prevent the gel for hardening unevenly. 7. The gel is expected to have

Reproductive Rights as a Historical and Feminist Issue Essay Example for Free

Reproductive Rights as a Historical and Feminist Issue Essay One of the biggest issues facing women in American society today has been an issue bouncing around in politics for decades: reproductive rights. Women can never have equal opportunity to men without equal opportunity to make their own decisions about their bodies. Reproductive rights for women not only include the right to abort a pregnancy, but it also involves any choice a woman may make concerning her body. She must have the right to choose when she wants to get pregnant, choose when she wants to have sex, have easy access to information about her body and reproductive system, as well as access to contraceptives and non-stigmatized medical care. Today’s women in American society still have to battle the right to information, the right to contraceptives, and the right to abortion. Sex Education in public schools has always been a widely debated topic in American History. Determining what information to give out and how old the children need to be is constantly being argued. However, many programs are only preaching abstinence, especially to young women. Young men on the other hand get the â€Å"condom talk. † Very little information about female contraceptives, physical or medicinal, is ever discussed in these sex education sessions. Rebecca Walker, in 1995, wrote that young women must be treated as growing, learning, individuals, and need information concerning â€Å"sex and access to birth control and abortion† in order to nurture their self-esteem and protect them from violence. With limited access to information, women are being denied the ability to make a fully cognitive decision about their bodies. Even women who have heard about female contraceptives tend to still only know very little about their options. Most women have only ever heard or relied on â€Å"the pill,† which during long-term use can sometimes have negative side effects on women. In its early stages of development and use, many women suffered severe side effects from the drug. The stigma against female contraceptives is very interesting. Could this be a resurgence of the idea that women should not have sexual inclinations? Female condoms, diaphragms, and other barrier methods besides the male condom can be confusing and intimidating for a woman to seek out, and many resort to the pill or â€Å"being careful. † In this instance both information and availability go hand-in-hand to allow women the knowledge to make an informed decision about their body. In 1891, Harriot Stanton Blatch (daughter of famous Elizabeth Cady Stanton) spoke out about a new term â€Å"Voluntary Motherhood. † She claimed that the upheld idea of motherhood as the highest moral position woman should strive to achieve was a lie, and that women who mothered unwelcome children were scorned. This creates another example of a double standard placed against women in society. The most notable of reproductive rights issues debated throughout history and into the present is the constitutionality of abortion. In 1973, the famous Roe vs. Wade Supreme Court case made all state laws against abortion deemed unconstitutional. However, lawmakers sought to impose regulations that still kept women from being able to control their bodies, defining who, when, and under what condition a woman could have the procedure. Many â€Å"pro-life† activists began criminal attacks on abortion clinics, 167 were reported between 1982 and 1997. [3] Feminists, especially in the second-wave movement, insisted that the choice of having an abortion was not a medical or criminal debate, but a â€Å"highly personal decision that belonged only to the woman who was pregnant. †[4] Women of color in American society during the 1970s also faced reproductive rights issues of their own. Many women of color in low economic standing were pressured into having sterilization procedures. These women were forced to make the life-altering decision usually while they were on the table just after delivering their child. Female sterilization of colored women at this time was equated to racial genocide, as it drastically cut down the predicted birthrate. Repugnant as this was, many states were chastised because they would fund these sterilizations but they would not support welfare programs to support these same families. Women should be able to make their own decisions about their bodies, especially when it comes to their sexual identity. Women should be able to decide whether or not they want to carry a child, and those who argue that women who deny motherhood are not listening to the women who argue for reproductive rights. Women need the power to control their bodies because that is the epitome of owning the power to be considered an equal in society. Women would not end up in abusive situations concerning their bodies if information and prevention were more readily available. With knowledge comes power, and that is proven in every argument through history. Argument for reproductive rights becomes a national topic every time the presidential race rolls around.

Functions of Enzymes in Metabolic Reaction

Functions of Enzymes in Metabolic Reaction Enzymes have a fundamental role in all metabolic reaction that occurs in all living organisms. Enzymes are proteins which has the ability to bind to substrates and break substrate into products. In most cases, enzymes act as catalyst as they aid the reactants to come closer by using their active sites. In this essay I will be reviewing the structure and function of a serine protease known as subtilisin and I will analyze the different techniques used by different researchers to define the structure or functions of Subtilisin. Subtilisin is found in various forms such as Carlsberg and BNP. All three enzymes are from different origins, however they have similar primary structure although, their tertiary structures are completely different. Subtilisin BPN is an extracellular protease enzyme of a spore forming organism Bacullus Amyloliquelaniens. This enzyme contains a single peptide chain of amino acid containing 275 residues with no disulphide bridges or SH group. The subtilisin BNP contains 8 right handed ÃŽ ± helical segment these regions are (Alden et al, 1970). Many distortion has been observed due to the standard helix. The longest helix contains a number of residues such as Ala 223 to Histidine 238 which runs all the way from the top of the molecule thought the molecules and to the other end. The other 6 helical segments lie approximately parallel to the longest helix (Alden et al, 1970). Subtilisins are example of serine protease these are found in every organism that exists. There are several examples of serine protease enzyme and one of them is alpha-Chymotrypsin which is one of the known enzymes in the Trypsin family. The Trypsin and the subtilisin are believed to have evolved as they have similar mechanism of action even though they are not detectably related. Subtilisin is a bacterial protease, however Trypsin including ÃŽ ±-Chymotrypsin, Trypsin and Elastase re from mammalian origin. These are the known enzymes to have evolved convergent because they have similar active sites and catalytic mechanisms but has no similarities in terms of sequence or conformational homology. The two known types of subtilisin are BNP and Carlsberg; both have similar polypeptide chain, but there are segments on the chain where a number of residues has either been replaced or deleted. According to Emil (1966), BPN consist of peptide chain of 275 amino acids residues, however Carlsber g enzyme contains only 274 amino acid residues. As mentioned in this paper, the chain is only different by 83 residues which may lead to the question why they are different . Furthermore, the similarities and differences between BNP and Carlsberg suggest there have been deletions which have caused both of these enzymes to evolve in different ways. These enzymes are believed to be serine protease enzymes which means they all originate from the same source and due to evolution these enzyme has been converging away from each others path and both enzyme adapted in its environment in order to survive. This resulted subtilisin to be present in bacteria and ÃŽ ±-Chymotrypsin is found in the mammalian pancreas. This now brings us to the point that ÃŽ ±-Chymotrypsin and Subtilisins having the same catalytic mechanisms. This suggest that both Trypsin family and subtilisin family originates from source. Serine proteases are highly specific enzymes as they use His, Ser and Asp part of their active site. The main characteristic of a serine protease is that they have a unique Ser residue of exceptional reactivity that forms a covalent bond with some of the substrates or inhibitors (Creighton J). In both Trypsin and subtilisin shows many similarity and both contains the particularly highly reaction serine residue which can be specifically phosphorylated by other substrate such as isoprophylfluorophosphate (Alden and Wright, 1970), sulphonated and acylated using different enzymes. Further, research was carried out to find out the protonotic equilibria exhibited by both of these enzymes. The enzymatic similarity between the two different serine protease could be the involvement of a Histidine residue as it has been mentioned in most literature. Previous studies suggested that tertiary structure of ÃŽ ±-Chymotrypsin and subtilisin contains hydrogen bonding involvement in the Enzyme-substrate complex (Polgar and Bender, 1969). The Kcat for hydrolysis of p-nitrophenyl acetate by BPN depends on a group with a pK of 7.2, which presumably was Histidine (Alden and Wright, 1970). Studies were carried out to determine the structure of the enzymes by Neidhart et al (1988) and they successfully refined the structure of Carlsberg. The structure was refines at 2.5 Ã… resolution using X-ray crystallography. Wright et all (1969) found out that subtilisin BNP possesses the catalytic triad, arrangement of active site including Aspartate, Histidine, and serine residues characteristic of the Trypsin family. Further study carried out by Robertus et al (1972), demonstrated that the arrangement and characteristics of the active site is identical for both BPN and other member of the Trypsin family, which means the peptide around the active site were highly conserved. In contrast, the overall peptide chain folding of subtilisin BPN reassembles those in the Trypsin family. Thus the relationship between BPN and mammalian Trypsin family of enzymes have been classified as a case of convergent evolution (Robertus et all, 1972). The catalytic triad consist of the residue Asp 32 , His 64 and Ser 221. This supports the charge relay hypothesis and the catalytic triad is the most important part of the serine protease as it helps the enzymes to work effectively. Subtilisin also contains calcium binding loops which contains abut 75-81 residues which is identical in both type of subtilisin (Neidhart et al, 1988). Subtilisin and ÃŽ ± Chymotrypsin both are highly specific as they only bind to specific substrates. For example, proflovin is a good competitive inhibitor for ÃŽ ± Chymotrypsin is inefficient against subtilisin. And oppositely subtilisin has a good competitive inhibitor 4-(4aminophenylaze)-phenylarsonic acid, where as it doesnt interact with Chymotrypsin at all (Alden et al, 1970). Despite the Histidine residue in the active site, some specific inhibitors still bind to the active site by acylation of the Histidine of the Chymotrypsin; however they do not react with subtilisin. There are differences between subtilisin and Trypsin; subtilisin does not contain any disulphide bridges, but Chymotrypsin has five and Trypsin has 6 which suggest that trypsins are more cystine rich. So apart from the surrounding area of the serine 221 in subtilisin, these two classes have no resemblance from each other as far as the primary sequence is concern (Alden et al, 1970).

Producerscareer Paper Introduction I believe by researching this career, I will learn more about what it’s like to be a producer. I also believe that my research will help me choose what occupation I’d like to have when I finish school. I chose this profession as the topic of my career paper because I want to learn more about it because I may be interested in going into this career. Job Description Producers have financial and administrative control over the making of movies, plays, and TV shows. Producers hire directors, principal members of the cast, and negotiate contracts with artistic personnel, often in accordance with collective bargaining agreement (â€Å"Actors, Directors, and Producers† 180). Together with the director, the producer also hires other members of the staff. A large staff includes several production assistants, associate producers, or assistant producers who are in charge of various parts of the production. These assistants help producers perform their task. During production, the producer is in charge of all the people involved in the movie, television, or theater project, including actors, directors, and production workers (CIC 154). Kaci Wall Anyone with enough money can produce a play or movie. A person successful in business who has contacts in the theater may raise the money to produce a play. Someone experienced in films, such as a director, may raise enough money to produce a film. Producers are entrepreneurs. The...

The Health Insurance Crisis in America Essay -- Public Policiy Issues

Health insurance comes as second nature to many of us. We grab that blue and white card and put it in our wallet and forget about it until we are sick or injured. When this happens, there it is, cushioning our fall like the extra padding it provided to cushion our wallets. This is not the case with everyone, however. Many Americans have no cushion to fall back on, no blue and white card to show the emergency room when they have an unexpected health concern. No HMO with a convenient co-pay amount when their son or daughter develops an ear infection. Medicine and other health services are expensive without these important conveniences that many people lack. These people have been â€Å"falling through the cracks† in U.S. health care system for years, leaving many citizens wondering: why would our country do this to us? Our great and powerful nation, the United States, a country that much of the world views as the most highly developed nation in the world, is the only industrialized country that does not provide its citizens with universal health care, according to a report by the National Rural Health Association (NRHA 1). Being that we are a capitalist economy, perhaps the government feels it is the duty of the people to make sure they are taken care of. This makes sense, doesn’t it? We are all smart individuals; we can make decisions and take action for ourselves. But what can the individuals do when the cost of insurance and health care is too high for them to handle? In the United States, the answer is nothing. A 2002 census published by the Public Information office showed that there are 41.2 million Americans who do not have health insurance (Bergman). That amounts to a startling 14.6 percent of the population, up from... ...ently, without expensive health insurance, Americans are in a bind. If they cannot afford health insurance, they surely cannot afford the medical bills that will fall upon them should they need to be hospitalized. Every other country in the world that is on the same level as America industrially and developmentally offers universal health care to its citizens. Some Americans are worried about the rise in taxes if the government offers guaranteed care to everyone. The insurance companies will suffer, as well. But the sacrifice is more than worth it. America was founded on the basis of freedom for all. Shouldn’t we all, regardless of income, be free to enjoy as many years of health as we deserve?

Pros and Cons of Outsourcing Essay -- Research Papers, Globalization

Pros and Cons of Outsourcing. 1. Introduction Globalization has lead to increase in international trade and a greater role for multinational corporations. With the rise of globalization many companies are turning to either off shoring or offshore outsourcing. In India and China, companies like IBM, Microsoft, Hewlett Packard, and Novell choose to get services from sub-contractors in these countries or move their development and support jobs there. Outsourcing is to contract out some of company’s activities to a third party company. The company who outsourced and the third party who is going to handle the activities for the company are joined by means of an outsourcing arrangement. This practice became even more popular after the dot-com crash of the early 21st century. As many businesses struggled with cash-flow problems, many investors were leary in investing money in high-tech companies, which many felt were still vulnerable to the dot-com effect. Struggling to do more with less, companies looked for less expensive avenues of development and support. For the United States, Indiaseemed like a perfect resource for these needs since most nationals speak english. A company can hire an engineer in India, for example, for US$10,000 a year where an equally qualified engineer in the U.S. could cost $60,000-$90,000 a year. Outsourcing has been big political issue as highly educated and highly paid IT workers lose their jobs. In this competitive environment, companies have to concentrate on competency and they want to outsource everything to reduce cost so the trend toward offshore outsourcing is increasing. Outsourcing threatens that in future US will not have many technology people.

The Placement Of Fibre Post Health And Social Care Essay

The arrangement of fiber station is a good pick for root treated teeth non merely because it strengthens the tooth but because it helps us to construct a probationary or unequivocal Restoration. The fibre stations can be a stuff of pick where aesthetic is the demand. They have high tensile strength and a modulus of snap similar to that of dentine. The fiber station is a inactive station which does non actively prosecute with dentine, hence adhesives and rosin cements are required to repair fibre stations in topographic point. However, adhesion of fibre stations depends on assorted factors including the features of root dentine, type of rosin cement, type of visible radiation, strength of visible radiation and the continuance of visible radiation. In an effort to get the better of these jobs, dual-cure rosin cements and adhesives are the stuffs of pick for adhering fibre stations with root dentine. However, few of the double remedy rosin cements still depend on visible radiation for t heir activation. To let the visible radiation to perforate in the internal facet of the root, glass fiber stations and quartz fiber stations are used as they allow the transmittal of visible radiation to the deepness of the root canal therefore leting the rosin cements to polymerise deep in the canal. Several surveies have been performed to measure the grade of polymerisation or transition values of rosin cements but most of these surveies used the microhardness trial instead than the more dependable Fourier transform infrared trial ( FTIR ) . Furthermore, most of these surveies were non performed in the root canals. The success of endodontic intervention non merely depends on the quality of intervention but besides on the quality of prosthetic device being placed to reconstruct the losing tooth construction. The structural loss of the tooth due to trauma, carries or both makes the tooth more prone to break. Therefore, station is placed in a prepared root canal infinite of a tooth with heavy structural loss to counterbalance for the loss of tooth construction. Some writers and clinicians suggest that the station provides strength to the tooth, while others suggest that the station makes the tooth weak due to the readying of the station infinite. However, many surveies support that the station should be placed in a tooth with heavy loss so that it can supply keeping for meantime or concluding coronal Restoration. Ideally, the station should hold the undermentioned belongingss: By and large, a station is placed into a tooth to retain a nucleus. A tooth which is to a great extent broken down frequently requires a station as the bing tooth construction is deficient and weak to retain the coronal Restoration. However, the readying of station infinite causes unneeded tooth devastation which may take to tooth break. Therefore, the arrangement of station should be considered where other options are non convenient.The determination to utilize a station depends on the staying tooth construction, place of the tooth in the dental arch and the functional demand of the tooth. A categorization described by Peroz in 2005 was formulated to measure the sum of staying tooth construction. Tooth with 1 axial wall missing is referred as category II normally known as Mesio-Occlusal or Disto-Occlusal pit, while tooth with 2 losing axial walls is described as category III normally known as Mesio-Ocluso-Distal ( MOD ) . If the staying axial walls in category II and III are greater than 1 millimeters so a station is non normally indicated as there is sufficient coronal construction nowadays to back up the Restoration. A survey performed by Steele and Johnson in 1999 showed addition in fracture opposition of category II and category III when they were restored with composite and amalgam merely. Class IV is described as a tooth holding merely 1 axial wall left. There is no addition in break opposition when a Restoration is placed. Therefore, arrangement of station is normally suggested in such scenarios. However, esthetically, non-metallic stations are preferred for anterior dentitions while for posterior dentitions either metallic or non-metallic station can be inserted. A tooth which has no staying axial wall or a tooth which is wholly decoronated is described as Class V. The interpolation of station becomes necessary in such instances as there is non adequate tooth construction which can back up the coronal Restoration. Furthermore, the collet plays an of import function in defying break in such type of instances. Ferrule is defined as a set of metal that wholly encircles 1-2 millimeter of sound tooth construction which resist longitudinal break. In 2001, Bolhuis stated that the crown collet is more of import than the station and nucleus. Metallic stations are stong and stiff, normally made of unstained steel, nickel Cr metals, Ti, Ti metals or gold plated brass.Stainless steel has a long history of use but it can do nickel sensitiveness in females due to the presence of Ni. Furthermore, Stainless steel can eat over clip. Therefore, Ti stations were introduced to get the better of corrosion. However, Ti and Ti metals have hapless compressive and flexural strength as compared to stainless steel, therefore they can non be used in thin roots. In add-on, Ti station may be hard to observe on radiogram due to similar denseness as that of gutta-percha and sealant.6.1.2. Non-Metallic PostsHistorically, during the old ages 1603 – 1867, Nipponese restored dentitions with wooden station and nucleus. However, due to hapless strength and break of wooden station, cast metal stations were introduce. In 1988, Duret came with the thought of non-metallic station and was deployed in Europe in the 1990s. Fibre stations can be smoo th or serrated depending on their surface features.6.1.2.1. Carbon fibre stationCarbon fiber stations are besides called C fiber-reinforced epoxy rosin stations. They consist of epoxy rosin which is reinforced with unidirectional C fibers parallel to the perpendicular axis of the station. The C fibers are made by the remotion of H, N and O from polyacrylonitrile by heating at 250C in air, followed by heating at 1200C in inert ambiance. The diameter of each fiber is 7-10Â µm, while harmonizing to weight, the fibers constitute upto 64 % of the entire weight of the station. Originally, C fiber stations were black in colour, but due to esthetic consciousness they are available in white colour besides. Furthermore, these stations were originally radiolucent but now they are available as radiopaque besides. Main advantage of C fiber station is the ability to successfully bond to dentine and modulus of snap similar to dentine i.e between 1- 4-106 pounds per square inch. Many Studies have shown increased strength of C fiber stations, while other surveies suggest their strength is less when compared with metal stations. Furthermore, few surveies have shown that C fiber station increase the fracture opposition of tooth, while other surveies report the opposite. In 2007, Ferrari reported 7.2 % of clinical failure rate of C fiber stations after 7-11 old ages. Failures were largely due to root break, crown debonding, periapical infection and periodontal disease. However, different surveies show different failure rates.6.1.2.2. Glass Fibre PostDue to dark colour of C fiber station, glass fiber stations were introduced. These stations are besides called fiber-reinforced epoxy rosin stations and are made up of glass or silicon oxide. Different types of glass can be use to do glass fiber station including vitreous silica fiber, electrical glass or high strength glass. However, the strength of the station depends on higher content of glass fibers. In a clinical survey, Ferrari ( 2000 ) placed 249 glass fiber station and observed 4.4 % failure rate over a period of 6 old ages. Another survey performed by Cagidiaco in 2007 showed 7.4 % failure after 2 old ages. Furthermore, Naumann ( 2007 ) placed 41 glass fiber station and found no failure during 3 old ages. Most common failure were relaxation of the stations, periapical infection, tooth break, debonding of Crown and break of stations.6.1.2.3. Zirconia stationIn 1995, mayenberg introduced zirconia station with a flexural strength of 900-1200 MPa. Zirconia stations have high break stamina, high strength and corrosion opposition and are made up of tetragonal polycrystalline zirconium oxide with 3 % mol Y oxide ( Y2O3 ) called Yttrium-stabilized tetragonal polycrystalline zirconium oxide ( Y-TPZ ) . Y-TPZ is 0.5Â µm in diameter, supplying smoothness and stamina to the joggle. However, due to smooth surface, the station does non organize a good bond with composite rosin and all ceramic Crowns. Furthermore, t here was no addition in bond strength even after the station was acid etched or salanized. Matinlinna ( 2004 ) stated that bond strength between station and composite rosin can be increased by tribochemical silicon oxide coating. The chief drawback of zirconium oxide station is that it can non be retrieved as it can non be grinded and supersonic remotion consequences in temperature rise. In 2004, Paul evaluated 145 zirconium oxide stations over a period of 9 old ages and reported no clinical failure when a direct composite Restoration with zirconium oxide station was placed, while there was 9 % failure in joggles with glass-ceramic nucleus Restorations. All failures were due to post debonding.6.2. Custom Cast PostThe most normally used stuff for usage station is cast gilded metal holding a comparable thermic enlargement and modulus of snap ( 14.5-106 ) to enamel. Furthermore, it is strong plenty to bear occlusal forces. However, arrangement of usage dramatis personae station require multiple visits and due to metal demoing from ceramic Restoration, the esthetics are compromised. Silver-palladium metals and high Pd content metals are besides used for usage dramatis personae station but they have inferior mechanical belongingss when compared with gold metals. Custom cast stations may be indicated when misaligned teeth require stations, inability to present antirotational characteristics in dentitions with less coronal construction or multiple dentitions necessitating stations.In 1989, Bergman reported 91 % success rate of usage dramatis personae station after 6 old ages.

Mass Media and National Identity

Gone are the days when the media used to exercise its power mainly through the radio and the newspapers. During that period, there was always time for free reflection on what it means to be an American. Today, the media merely thrusts its views on the viewer in a very powerful way. People are being exposed to a hugely expanded power of the media through the incessant television programs, movies and the internet.Like an invader who captures the minds of the weak, the American media is now in a position from where it can brainwash people into developing a media customized American identity. One of the more dominant images being circulated right now by American media is that to be American is to agree with the American President. All those who disagree are anti-American.Ever since the war on terrorism was launched during the aftermath of September 11, 2001, political leaders have used the media to seed the hearts and minds of Americans towards a new kind of patriotism. The Bush administ ration has, with the help of the media, widely propagated that this is the time when America needs to come together and support the President. The message is that unity and support for the President is more vital than having a healthy debate. This communication strategy has garnered a great deal of success in the United States as anti-war and anti-Bush policies have become equated with anti-Americanism.National identity of America was earlier derived from powerful figures of colonial America who imparted their daring visions, power, and energetic optimism to the American tradition. Among them are the explorer and colonial founder John Smith; the religious liberty advocate, Quaker, and colonial founder William Penn; the great Puritan intellectual Cotton Mather; and the astonishing 18th-century polymath Benjamin Franklin. Americans of the early 19th century were involved in the great controversy of whether slavery should be abolished or not.They were not afraid to fight wars for their causes and they also ensured that the republic achieved astonishing economic growth. Writers such as Ralph Waldo Emerson and Louisa May Alcott helped in the development of a mature distinctive American literary and philosophical culture. There were great leaders like Franklin Roosevelt and Abraham Lincoln who turned America into a great prosperous nation of sustained economic growth and they enabled the republic to stretch from ocean to ocean. America flowered as a land of great diversity with the advent of immigration in the mid-20th century. This was the time America grew to be a global leader and American character was exemplified through distinct American traits found in its great citizens.Some such distinct American traits that became part of American identity were lack of fatalism, energetic approach to problem-solving, faith in economic growth, dedication to education, devotion to religious liberty and belief in equality. There were many individuals who embodied these Americ an traits. Louisa May Alcott was a volunteer nurse in a Civil War hospital, where she contracted typhoid fever and was crippled for life from the mercury used to treat her. But that did not deter her from writing Little Women, a book that was hugely successful. Benjamin Franklin was the epitome of self confidence as he invented the Franklin stove to meet the firewood shortage in Philadelphia.Andrew Carnegie was a great industrialist who finally thought it best to focus on a single industry: the steel industry. Horace Mann was responsible for the creation of the universal compulsory school model. The Virginia Statute for Religious Freedom, which Thomas Jefferson drafted in 1786 was the foundation stone for the rise of America as a nation that valued freedom in all aspects of life.   Every American shares a national identity with his fellow citizens and he is proud to known that values such as optimism, self reliance and belief in equality and justice are all part of this great Amer ican identity which has been shaped by a long history of political openness and change, tolerance of conflict, entrepreneurial energy, and cultural mix.The nobility that is enshrined in American national identity is slowing being eroded in the aftermath of the September 11 attacks, the Clinton-Lewinsky scandal, race relations, crime, immigration, health care, euthanasia, gun control, and education and the erosion is more intense due to the focus of the media on such issues. Media expert David Domke feels has studied the government’s post-September 11 communication strategies in the war on terrorism as well as the media response and the impact on U.S. public opinion.After studying media reports and public responses from the period from September 11, 2001, to Bush's address to the nation about Iraq on March 17, 2003, he concluded that â€Å"government officials have consistently emphasized American core values and themes of U.S. strength and unity while simultaneously demonizi ng the enemy† (Whitworth Communications, 2003). His conclusion is supported by a study of media coverage and public-opinion polls. Words such as freedom, individualism, mobility, and pragmatism â€Å"speak to the American spirit.† It is through the use of such words that mass media is shaping the national identity on political issues.There are people such as think-tank researchers, interest-group leaders and academic experts who can offer analysis from a neutral platform. They are not people who are likely to sing chorus to the government’s song. But Domke and his colleagues have found that such intellectual people tend to get less media attention – for the simple reason they are not guaranteed supporters of the government.This finding shows that the media coverage under the blanket of patriotic press coverage, has served to shift the American national identity from one that allows every individual the liberty to have his or her own opinion on political is sues to one that supports the standing of a unified nation behind the President of the United States, no matter what decisions he takes.Apart from this negative shift, there are many positive ways in which mass media is helping to shape the national identity of Americans. Hollywood is one of the most influential media in America and has always played a huge role in creating a sense of national identity and pride. American values such as equality, liberty, love for the nation, freedom of expression, human right are emphasized in many movies.Popular movies such as Pearl Harbor; We Were Soldiers; The Quiet American; Behind Enemy Lines; Black Hawk Down; Kandahar; Collateral Damage; In the Bedroom; Minority Report and Fahrenheit 9/11 explore and help in shaping American identity with respect to morality, family, nation and globalisation.Television programs such as Apprentice and American Idol showcase the potential America offers to people with values, talent, skill and willingness to wo rk. They add a sense of pride and positive attitude to the national identity. Sports such as baseball and basketball as shown in the movies and television programs have become American symbols of competitiveness and professionalism.However, television advertisements seem to focus more on hawking a happier home and love-life, improved eating and drinking and appearance, better health, taste and smell, a more comfortable car, etc., etc. thereby polluting the national identity with a craving for materialism and self centeredness.Through the mass media, Mickey Mouse, Babe Ruth, screwball comedy, G.I. Joe, the blues, â€Å"The Simpsons,† Michael Jackson, the Dallas Cowboys, Gone With the Wind, the Dream Team, Indiana Jones, Catch-22 – these names, genres, and phrases from American sports and entertainment have become a powerful tools in sculpting the American identity. Through mass media, music has also played a huge role in shaping American identity. The first major compos er of popular music with a uniquely American style was Stephen Foster (1826-1864). Soon the music that was representative of America combined elements of European musical tradition with African-American rhythms and themes.Some of Foster's best songs are: â€Å"Oh! Susanna,† â€Å"Camptown Races,† â€Å"Ring the Banjo,† â€Å"Old Folks at Home†. Today, the inclusion of African music such as Reggai and rap, Latino rhythms, and the domination of global artists has made American music much more representative of its expanding scope of national identity. However, rock music remains the prevalent pop music of America because it is one genre that can assimilate almost any other kind of music, along with new varieties of outlandish showmanship, into its strong rhythmical framework – much as America assimilates different cultures and different races into its constitutional framework and national identity.Rangers in the Sequoia National Park report that the huge sequoia monarch trees in the forests, however huge and seemingly strong, one day simply tilt over and crash to the ground because of their weak roots (Sites, 2007). So also the American national identity built through mass media can crash if care is not taken to nourish the roots of that identity. Mass media should focus on the unique American history and resplendent traditions instead of favoring an almost total obsession with the clamorous present and the dubious lures of the unpredictable future.Bibliography:Whitworth Communications (2003).

Eco Plastic Solution Essay

This case focuses on determination of the cost of capital for a firm. The student determines the cost of individual sources of financing, including long-term debt, preferred stock, and common stock. The cost of debt is adjusted for Eco Plastics’ 40% tax bracket. The company is considering a new financial structure, with the replacement of preferred stock financing with debt financing. Additional use of debt increases the common stockholders’ required rate of return. The student is asked to compare the two weighted average costs of capital and identify the better financial structure for Eco Plastics Company. a. Cost of debt: Proceeds from sale of $1,000 par value bond: $1,000 − (average discount & floatation costs) $1,000 − ($45 + $32) = $923 Subsequent payments: Interest payments ($1,000 Ãâ€" 0.105) + Par value Before-tax cost of debt N = 20, PV = $923, PMT = −105, FV = −1,000 Solve for I = 11.50% After-tax cost of debt: ri = rd (1-T) = 11.5% (1−0.4) = 6.9% b. Cost of preferred stock: rp = Dp à · Np = (0.095 Ãâ€" $95) à · ($95 – $7) = $9.02 à · $88 = 10.25% c. Cost of common stock: rj = RF + [bj Ãâ€" (rm − RF)] = 0.04 + [1.3 Ãâ€" (0.13 − 0.04)] = 0.04 + [1.3 Ãâ€" 0.09] = 0.04 + 0.1170 = 15.7% d. Weighted average cost of capital: ra = (wi Ãâ€" ri) + (wp Ãâ€" rp) + (ws Ãâ€" rn) = (0.30 Ãâ€" 0.069) + (0.20 Ãâ€" 0.1025) + (0.50 Ãâ€" 0.157) = 0.0207 + 0.0205 + 0.785 = 0.1197, or about 12% e. 1. Change in risk Premium: Change in beta Ãâ€" market risk premium = (1.5 − 1.3) Ãâ€" (0.13 − 0.04) = 0.2 Ãâ€" 0.09 = 0.018 Shareholders require 1.8% more per year New cost of common equity: rj = RF + [bj Ãâ€" (rm − RF)] = 0.04 + [1.5 Ãâ€" (0.13 − 0.04)] = 0.04 + [1.5 Ãâ€" 0.09] = 0.04 + 0.1350 = 17.5% Note: 17.5% − 15.7% = 1.8% 2. Revised weighted average cost of capital: ra= (wi x ri) + (ws x rn) = (0.50 Ãâ€" 0.069) + (0.50 Ãâ€" 0.175) = 0.0345 + 0.0875 = 0.1220 3. Eco Plastics’ CFO should retain the cheaper current financial structure. Replacing preferred stock financing with debt financing results in more risk to the stockholders. The increase in stockholders’ required rate of return is more than offsets the advantage of using the low cost debt. If Eco Plastics’ CFO were to revise the capital structure, share price would fall and shareholder wealth would not be maximized.

The Moral Problem Of The Death Penalty Essay Example | Topics and Well Written Essays - 750 words

The Moral Problem Of The Death Penalty - Essay Example America has done x amount of damage and must pay Canada for that. There are several problems with this, however. For one thing, the environmental damage will affect people who will never get money from the restitution. Furthermore, environmental degradation can be long term in a way that neither Canada nor the US could predict, so it is possible that any payment that the United States makes would be insufficient. There are several other options, however. Canada has an abundance of hydropower, which is how it can operate more greenly than America. Canada could agree to sell hydroelectricity to American municipalities close to the border, reducing their need for coal. But probably the best solution would be for America to agree to a plan to move away from coal power, avoiding the environmental degradation entirely, while possibly making economic restitution for damage already done.3. The line of thinking that â€Å"If you’re not doing anything wrong, you don’t have anyth ing to worry about† in terms of surveillance is patently ludicrous. There are a wide variety of things that may not be morally or ethically wrong but should not be public knowledge. If, for instance, a high school teacher happens to be a gigantic fan of Justin Bieber, have many of his decorations and listen to his music all the time, this is far from morally wrong. But it is also possible that his high-school teacher’s life would be more difficult if his students found out about his love for Bieber.... But it is also possible that his high-school teacher’s life would be more difficult if his students found out about his love for Bieber. Furthermore, it is not wrong or right to practice any particular religion or align one’s self with any particular political party, but one could face challenges in their personal or professional life because of widespread knowledge of this. 4. The boss is fundamentally assuming that his or her employees are doing things they shouldn’t be at work, and refusing to trust them. This monitoring should usually not be justified and is usually not a good management tool. For one thing, as long as an employee is meeting their job expectations then what else they do at work should not be at issue – if, as an employer, you have a problem with someone’s performance than you address it, as a performance problem, and if there is no problem with their performance you have no reason to have to monitor confidential information. Thi s could even lead to decreased productivity – for some people surfing the internet to give their brain a break might be an important part of what they do, and interfering in that could make them less productive. 5. This is a very interesting question. Seat belt laws from adults are very different than seatbelt laws for infants, because infants are not able to make these decisions for themselves, and society has decided that there are a lot of ways that they need to be protected, even from their parents (for instance you can’t give an infant poison they might eat either). In the case of an adult though, you could say that the adult taking those kinds of risks provides problems for the rest of society (for instance tying up

Qualitative Social Research Essay Example | Topics and Well Written Essays - 500 words

Qualitative Social Research - Essay Example used to define the control and social control mechanisms of the state in terms of gender, stating that males are in a position of power and women in one of sublimation. As one source shows, using a qualitative method of case study analysis, patriarchy can be applied to the role of the state in women’s issues to explain inequities in the system. â€Å"The social roles men and women occupy may account for gender differences... Women are thought to have poorer experiences within any given role (role strain theory), have more conflicts among their different roles (role-configuration theory), or have fewer role opportunities available to them (role accumulation hypothesis) compared to men† (Ericsson and Ciarlo, 2000). These researchers realize that there are also other various gender role theories which use the patriarchy as a target of oppression and as a way of explaining why women in state institutions have sometimes been overrepresented historically in terms of certain perceived illnesses that were often socially based. Other sources take a more cultural view, rather than a social and historical view, when it comes to the problem of gender and how it has developed to the modern day. â€Å"Television’s first and strongest impact is on the perception that women have of the public male world and the place they have in it. Television is an especially potent force for integrating women because television brings the public domain to women† (Spigel, 2001). This is one common argument using popular culture, and represents the search for a more personal vision. â€Å"Postwar media often suggested that television would increased women’s social isolation from public life by reinforcing spatial hierarchies that had already defined their everyday experiences in patriarchal cultures† (Spigel. 2001). There are many perspectives with which to define these issues. Although feminist perspectives on gender may focus on historical change within their portrayals, they are

Business ideology Essay Example | Topics and Well Written Essays - 500 words

Business ideology - Essay Example The centralized, authoritarian technology is portrayed as bad technology that squeezes the human spirit and manipulates people’s minds. Apple personified the Mac as the good technology – independent, individualized -- that can liberate the individual from the bad technology. Microsoft presented a similar ideology with the message by CEO Steve Ballmer (1986) that depicted Microsoft providing people-ready computing. Microsoft claimed that their innovations facilitated the supremacy of people. A comparison with IBM in the form of a direct assault, Microsoft declared that the pitch of IBM is to help companies with its innovations, at Microsoft the tone is to give power to the people to innovate. Microsoft, like Apple, emphasized the ideology of empowerment by making a striking contrast to IBM as the veiled power behind the centralized, spirit-subduing hegemony. In effect, Microsoft was duplicating Apple’s ideology and strategy. But Apple’s approach went deeper than its marketing implication. Apple advanced the integration of its technology as the nucleus of its strength. By keeping up a closed system, uniting proprietary software and hardware, Apple could provide, it asserted, a more enhanced user experience. The message was: You did not have to be bothered about the technology – it simply worked – so that you could focus and be creative on doing your work. Microsoft, which built up its market dominance in PCs on an open structural system, is now embracing the Apple strategy as well. Microsoft claimed that its integrated platform of corporate software provided a better enhanced user experience, from the operating system to the desktop application. Microsoft argued through Jeff Raikes (Business Week, Mar.2006) that Microsoft offered more capabilities by product integration, a blend of technologies having more impact. Again the message was: Liberating people to innovate. Would this integrated ideology work for Microsoft? It may be recalled

Biology science of duty Essay Example | Topics and Well Written Essays - 1250 words

Biology science of duty - Essay Example The most important feature of this system is the basic rule of adherence to the duty no matter what the consequences are following the duty. The system stays irrelevant from the end result of following the principles for the justification that the duty has to be performed by any means. When any theory is presented criticism comes along and has a few important features also. The basic feature of this system is following the duty in any circumstances but the harmful fact of the duty has to be over looked. The consequences have to be chosen over the least possible one and the duty which is less harmful after the duty is enacted. The use of utilitarian system simply distinct form the above mentioned one in a simple manner where the consequences are known and cannot be chosen and a series of data should be available. The rules of this system make it available for short term use where no importance is given to length examinations. It poses environmental problems and causes an impact to human life due to different way of approach towards life. The draw back of this system is that it fails to define prohibitions and find the importance of species. Both the species of humans are put into account and considered similar in any context but when put under large consideration animals are compared to humans and their well being also. Considering everyone the same and all given the same importance the species which need more attention come under scrutiny where they are similar to other species which do not need much of importance which makes this rule another draw back of this system 2. Explain three major differences between mitosis and meiosis. How does each difference contribute to the outcome of the process 2. Every living cell is composed of genetic material called DNA which carries chromosomal structure of an individual. The changes that take place in an individual and growth of the tissues are attributed to the changes that DNA undergoes during mitosis and meiosis. The main differentiating features among the two are as follows: Mitosis can be generally defined as formation of two daughter cells from one; it can be simply explained as differentiation of the genetic material into two cells. The example that can be given to explain mitosis is the growth of tissues in skin, multiplication of blood cells. Meiosis on the other hand can be differentiated from its meaning; reduction in the number of chromosomes into half and also involves the changes in DNA structure. The example that can be given here is the formation of foetus that is the end result of the above mentioned process. The other main differentiating feature that can be mentioned here is after the process of mitosis the number of cells that are formed are two in number and have genetically same features and chromosomes as that of the mother cell whereas after Meiosis the number of cells that are formed are four in number and have different set of chromosomes and their genetic structure varies. Mitosis is the process which generally occurs in somatic cells whereas Meiosis is the process

Article on a Person I Admire Essay Example for Free

Article on a Person I Admire Essay Depressed bulimic is a role model However inadequate to being a role model a depressed person struggling with bulimia might seem, our history holds an unquestionably notable one. Married to The Prince of Wales, Diana Frances became the first high-profile celebrity to be photographed touching an HIV-infected child and at once the most loved Princess of all times. Her life and activities had a significant impact on changing people’s attitudes and making the world a better place, for which I admire her greatly. The first Englishwomen married into the Royal Family had it not downhill, but no sooner had she been allowed to speak for herself irrespective of the Palace opinions than she became immersed in numerous charitable causes including getting involved in the AIDS research, which was strongly disapproved of by the Royals. Despite all criticism Lady Di continued throughout her marriage to patronise over one hundred nonprofit organisations. Increasing public awareness of the land mines issue and its dreadful consequences is also an achievement we should ascribe to The Princess of Wales. Doing all the charity stuff is, one may say, one thing and changing people’s lives is another, but still we have to give credit where credit is due, and the „Queen of Hearts† sure deserves one. Having problems as serious and discomforting to talk about as the rest of the nation (loveless marriage, bulimia, depression) and openly talking about them brought her closer to people than any other prominent figure has ever been. Her strength and confidence while overcoming seemingly insurmountable obstacles inspired others and encouraged them to make the best of a bad job. Although it has been over a decade since her death, Princess Diana is still looked up to and thought of as a women who was at once a royal personage and a compassionate friend. She would use all the media attention she was being given due to her position, status and fame to help those in need, especially the victims of diseases, poverty and social intolerance. (337)
