Bioterrorism - The dangers, effects on society, and the actions of the government. You wake up early for work and kill your family goodbye. On your daily transit you see a man drop a glass vial in the subway, but you think nothing of it. Moments later you become a statistic. A statistic of Bioterrorism. The threat of Bioterrorism, long ignored and denied, has heightened over the past years and needs to be publicly addressed. Today's biggest hazards are anthrax and smallpox, yet people are left uncertain at what should be done while the government goes undercover to solve the problem as the media is left to give its own over exaggerated version of everything opinions on things.Although terrorists could use many disease-causing agents, experts on biological warfare regard anthrax and smallpox as the two biggest hazards. Other infectious diseases that pose a threat include plague, tularemia, botulism and tuberculosis. However, experts believe these organisms and diseases are unlikely to cause widespread illness because they're difficult to manufacture and distribute.E nglish: A transmission electron micrograph of sma...These organisms are also less hardy than anthrax is.Anthrax is caused by Bacillus anthracis and its spores. Anthrax can infect people in three different ways. Cutaneous anthrax develops when the bacteria enter your body through superficial cuts or wounds on your skin. The vast majority of anthrax infections are cutaneous. Intestinal anthrax results from eating food contaminated with the anthrax bacteria. Inhalational anthrax occurs when you breathe the anthrax bacterial spores into your lungs. This form of anthrax is usually fatal.The death rate for anthrax from inhaled sources is very high, approaching 100 percent. Death rates are lower for anthrax that enters your body through food or a wound. Anthrax is not transmitted from person to person, the way a cold or influenza is passed, therefore, it cannot spread in large populations. However, microbiologists consider anthrax a serious...

But primary sources are not enough. Few essay topics require a round up of only one kind of source. In order to provide depth of research, a writer will need to combine primary and secondary sources.

It is important here to turn off the filter and let the ideas come out. Connections between various ideas are important and these can be established by brainstorming.

There are a lot of problems with the cost and delivery of healthcare in today's world. We need to find solutions for these problems. My thesis is that Obamacare is not the solution for state healthcare reform. Obamacare will not reduce costs. It will not make insurance cheaper or better. And it is infringement of states' rights. ESSAY One of the most important things for businesses to consider when starting up is whether to how much of their employees healthcare costs they should pay. This is part of a great debate about healthcare and whether the state or employers should pay it or whether people should be responsible for it themselves. It comes down to the basic question: is healthcare a private or a public good? This is a question that states in the United States are currently struggling with. The cost of delivering healthcare is rapidly increasing and becoming a very large portion of the budget of many states. It is unsustainable. At the same time there are many people who remain uninsured either because they have fallen through the cracks or do not have a job that provides them benefits. These are serious problems that many states are facing. Some believe that President Obama's healthcare reforms—Obamacare—are the solution to these problems. However, they do not do much to reduce costs, they force people to buy insurance which is probably unconstitutional, and they will not work. They are not the answer to reforming healthcare in the states. Those who believe healthcare is a public good believe everyone has a right to it and that it is an abuse of human rights to not be granted publicly-funded health insurance at birth. They think that people are effectively tied to their jobs because they are afraid to lose their hea lth insurance. They also argue that it seriously reduces labour flexibility and affects productivity as people stay in jobs they might not want just so they maintain their insurance. There are others who believe the opposite. They would like to see a smaller state that is not responsible for everything in everyone’s life. What could be more personal than health? Why should the government or a business be responsible for paying for an individual’s health? It’s your own choice, for example, whether you smoke or don’t exercise, and yet the business or government must pick up the tab. These is part of the unconstitutional nature of these reforms. The constitution's commerce clause does not permit the government to force people to buy a particular product such as insurance. The costs of enforcing this will be very high. People would probably also lose access to their own doctor if their employer found a cheaper option due to the bulk-buying of insurance plans. That would be good or fair. There area better solutions to reform healthcare. One

Rickshaw by Chinese literary great Lao She Essay Example for Free

Rickshaw by Chinese literary great Lao She Essay Through telling the story of Xiangzi, Lao Shes Rickshaw moulds a woman in Hu Niu that is the antithesis of everything that a woman should be in the traditional society of that period. In the time-honoured Chinese culture, there has long been a strong prejudice against women of power. Every unfavourable image has been linked with particularly those who have proved especially formidable. Throughout the histories that have been written by mostly men where views as traditional as Xiangzis have been prevalent, dominant women have been presented in the most unsympathetic light. In similar fashion, our look at the character Hu Niu is relentlessly coloured by Xiangzis harsh narrative. It is impossible to do a light reading of Rickshaw and hope to be presented a face for Hu Niu that is to true to her actual person. Therefore, in order to ensure that our understanding of this distinctive woman is holistic, we must consider two issues: what sort of social influences have manipulated Xiangzis point of view; and what is Xiangzis innate character that so overwhelming pre-ordains the way he thinks. Only after peeling back such layers do we see a depiction of Hu Niu that is not peppered by biases. Only by doing our own commentary on the story do we hear the point of view of who is not talking and what is not being told, and that is the narrative of Hu Niu herself. What we subsequently come to realize is that, due to his wild prejudices, Xiangzi has rejected his best chance of escaping the rickshaw-pullers misfortunes when he rejects Hu Niu. In the broader sense of the Chinese history, women who have held power have often been blamed as the cause for ruin of an entire dynasty period. Historians have, for example, always blamed the downfall of the Qing dynasty on solely Empress Cixi and her refusal to recognize the changing times around her. In a more specific sense within the context of this novel, Xiangzi presents Hu Niu as the woman who is fully to blame for causing the downfall of a man. Women who strayed away from the traits that society norms dictate are seen as abnormal. In the same way, Xiangzis descriptions are most discriminating when revealing thoughts about any strong woman in his life, and he especially vilifies Hu Niu. This is not unlike the negative ways that dominant women like Empress Cixi and Empress Wu Zetian have been  represented throughout history. Under Confucian beliefs, it has been highly regarded the notion that the best types of women were the virtuous ones who may show maternal instincts before they even marry towards their younger siblings and widower fathers. There have always been deep-seated attitudes that have limited womens access to power. Patriarchy being the norm of the culture, a womans position within her family and the social hierarchy was as a dependent, not leader, of men. The tendency has been to assign women and men different roles, and womens special reproductive functions, of course, encourage this division. Often, the sharply restricted participation of women as competitors raises questions about a females ability to command. In actuality, women are by nature no weaker than men. As a generalization, certainly, they may be physically slighter and their characters gentler, but this does not equate to them being fundamentally powerless, useless, hesitant, cowardly, or able to survive only by obeying men. Scientists and historians have devised systems to analyse the workings of the world that, coincidentally, protect their own interests while oppressing and dominating women: the theory of Yin and Yang, for example, was established to demonstrate that, inherently, the female sex (yin) is linked with softer elements of the world such as stillness, inwardness, or earth, etc., while the male (yang) is linked with much stronger elements such as motion, outwardness, sky. Commanding and opinionated women were seen to be transgressing this boundary of yin and yang. Women who yielded power and used their skills in mind games to manipulate situations to their favour are seen as masculine and unnatural. Women who used their sexuality were seen as even more improper. Regardless of their individual personalities and abilities, females have been perceived as too weak, irrational and emotional to rule. This sentiment is shown in a Chinese saying that stated: A woman ruler is like a hen crowing . As we see from the beginning of his tale, due to Xiangzis traditional views,  his dream is to someday marry a robust and honest country girl after making enough money . As a result, it is apparent to us that the foundation of Hu Nius very nature had doomed her from the onset to be the recipient of all of Xiangzi prejudices. The precise manner in which she came to catch Xiangzi in marriage ignited every one of his prejudgments against women, especially against those who yielded sexual power. Xiangzi is incredibly scared of sexual women, but he mostly piously masquerades this fear as loathing or distaste. The morning following Hu Nius seduction of him, Xiangzi is thoroughly disgusted by the thought of Hu Niu, whom he deems as ugly, old, nagging, and shameless (54). So despite the fact that the warlord soldiers has so heartlessly robbed from him the first rickshaw he had loved so passionately, in Xiangzis mind they are still nowhere near as despicable as Hu Niu is (54). The fact that all the wrongs in the world that have been done onto him did not compare to the hurt done onto him by sex-hungry women attests to his outright prejudice. After Hu Niu gains some knowledge from Xiao Fuzi about the variety of physical acts, she proceeds to use Xiangzis body to find her lost springtime (172). This enrages Xiangzi, who subsequently believes that Hu Nius cooking for him and caring for him is merely attempts to fatten him up to make him her plaything (152). Xiangzis disdain for sexual women also manifests itself in the way he sees Madam Xia, as merely a woman who could give him a little extra cash (204). Xiangzi always tries to find safety in reverting to look down on the women whom he secretly finds intimidating. He does not like Madam Xia because he finds her to be a little terrifying, the way Hu Niu had been terrifying (204). He feels that Madam Xia brought with her all the harmfulness and destructiveness of the female sex that he had already tasted before and hated. His scorn for sexually predatory women is confirmed by the fact that he feels Hu Niu and Madam Xia were the same line of goods (204), meaning both women were strong, calculating and impure. Xiangzis view had been shaped by the fact that society as a whole only accepted women who exhibited bashfulness and mildness. History tends to vilify Empress Wu Zetian, for example, and tell stories of her sexual appetites . She harboured imperial ambitions of becoming emperor and was indeed perhaps one of the most able of the Chinese emperors. In attempts to regain her youth as she aged, she kept  a number of young men as her companions , no different from the way both Emperors and ordinary men alike all kept concubines. But history has been quick to condemn the gender reversals and sexual excesses of women as abnormal and uncivilized. Xiangzis little regard for women also encompasses his prejudice against financially minded females. We as readers notice immediately how much more intelligent Hu Niu is than Xiangzi, but he only sees her as manipulative. Hu Niu recognizes that brute strength is hardly the only way to make a living. Her business sense shows clearly in her immediate idea to rent out a room to Xiao Fuzi to aid the latter in the entertainment of men, or her quick thought to rent out the rickshaw to Ting as opposed to letting it sit idle when Xiangzi caught pneumonia from the summer storm (184). She has it meticulously planned out of how much money to spend on what items. Hu Niu is astute about what actions can be taken when money begins to decrease. She suggests that they go back to Old Liu, act submissive, and make up with him for the fight she had with him; she knows that she needs to given her father face, that he needs to be flattered and cajoled. She calculates, albeit too late, that by submitting to Old Liu, she and Xiangzi would be able to get the mans money legally in the proper line of inheritance (147). We see Xiangzi subsequently admitting to himself that none of this had ever occurred to him (148). Yet, even though he admits that he had never thought Hu Niu would have a plan like that in mind, and now he had an idea of her smarts, he still refuses to agree with Hu Niu. His stubborn reasoning is that he does not want to be the wifes toy nor the father-in-laws lackey (149). But he himself has no other ideas. The absurdity is clear in the fact that his only argument is, he just does not want to loaf, and pulling a rickshaw is all he knows. Xiangzis prejudice against economically minded females is also seen in his disregard for Kao Mas advice regarding savings and investments. Kao Ma tries to teach Xiangzi how money breeds money and is herself very adept in modern financial strategies (70). Although Xiangzi thinks Kao Ma is perfectly nice and is one of the very few women whom he respects, her advice to him is very quickly dismissed by Xiangzi simply because she was merely a  woman. He trusts only himself, and when he adds up his money on his own, he promptly decides that it is much safer kept in his own hands (72). His entire mind is centred only on safekeeping the money that he has. Besides laboriously pulling a rickshaw for a seemingly infinite period of time, his mind is nothing like Kao Mas or Hu Nius regarding how to use the money one already has to earn more. Xiangzi in fact feels that his deathlike grip on his money is worthy of respect, and even though Kao Ma was a nice enough woman, he sees no advantage in following her advice (73). Even when Madam Fang, an old employer, had urged him to open a savings account, he promptly rejected the notion because, through his warped logic, he felt that the cash in his hands was much better than the numbers in a passbook (71). One can not help but think that if it were not the Madam Fangs and Kao Mas of the world giving Xiangzi these advice, if in fact a man Mr. Cao, perhaps had done so, Xiangzi would certainly have listened much more seriously. Xiangzis loathing for being under Hu Nius control is a reflection of the fact that, throughout history, there have been blatant biases against female rulers. That a female could gain power over men and an entire country thereby abandoning the path set up for her by society was not accepted to a huge degree. Cixi, likely the shrewdest woman of all of Asia during her period, has been credited with the some of the worst things to befall her era. Much has been said about her rule as being the significant contributing factor to the ruin of a nation. Be that as it may, her control stems from power she fought for and won for herself. She rose from the lowest positions of a fifth rank concubine to what was eventually considered by many at the time as the only man in China, and likely exercised more power than any woman in that time . Another illustration of the bias can also be found against Empress Wu Zetian. Likely one of the most influential and oftentimes misunderstood rulers of Tang Dynasty China, she controlled the empire during one of its more peaceful and culturally diverse periods . Some may say that she was ruthless in her desire to gain and keep power, but others may say that she merely did what she had to and acted no differently than any male emperors of the same period. The kinds of behaviour criticized in men are dramatically different than those criticized in women, especially one dominant and deviant enough to rule an empire. It should be no surprise to us, then, that Xiangzi, someone who is determined to be dependent on only his own size and strength, should find is so unbearable to be controlled by a woman like Hu Niu. Xiangzi is dogged about relying on nothing more than his own muscles, and he mistrusts a woman who uses shrewdness and mind game to get what she wants. To him, Hu Nius calculating proposals are shameful, and he hates having to be at the mercy of her dominance (149). The fact that a woman ordered him about was insufferable for someone as headstrong as Xiangzi. This loathing comes to such a height he eventually declares that he is glad that she is dead because she had always oppressed him (218). He believes anyone who is powerful or calculating to be evil and deserves to die. Despite the fact that Xiangzis hatred has been building since his meeting of Hu Niu, the severity and mercilessness of his venom here is still surprisingly startling. Xiangzi states that the only people he thought deserves to live was himself and Xiao Fuzi, who is loyal and honest (218). Such a statement reveals to the reader that if Xiangzi is ever at all capable of empathizing with anyone, it is only with the passive and the meek. Xiangzis discrimination against Hu Niu cannot be fully understood until we get a feel of his ode to Xiao Fuzi. The earliest we observe of his intolerance for women as a whole is when he purchases his first rickshaw and the only class of persons to whom he simply refuses to grant a ride are women, who are, in his opinion, an indication of bad omen (10). More appropriately, we could say Xiangzis bias is most concentrated against specifically those women who know what they want and stops at nothing to achieve it. We see that the only woman in this entire novel of whom he sings high and unfettered praises is the one woman who is different from Hu Niu in every possible way: simpleminded, thoughtless, compliant and sweet Xiao Fuzi. As we know, tradition calls for women to have no opinion, listen to the husband, be tolerant, be useful and not be afraid of hard work. Xiao Fuzi is the epitome of the perfect woman of Xiangzis dreams. Even when Hu Niu is making Xiao Fuzis life miserable and her business difficult, the latter is still capable of swallowing her tears, and humbling herself by throwing herself at Hu Nius mercy. The bearing of disgrace by kneeling  before Hu Niu is the most admirable of sacrifices (188). Xiangzi loves Xiao Fuzis mildness and it shows in his fondness for her companionship and conservations (186). With Hu Niu, he never got the last word. Xiangzi can only tolerate a traditional woman who listens to men. Therefore, in Hu Nuis devotion to Xiangzi, we see that her love could never find reciprocation or fulfilment. Furthermore, we can deduce for ourselves that if Xiao Fuzi was not someone who handed her whole life over to himsomeone who needed a man like himsomeone whom he could rescue (224), nothing about her either would have been any allure for Xiangzi. If Xiangzis opinion were the only narrative in the novel, then simply after considering his side could be the end of our story. After all, this novel is centred on Xiangzi the repetition in his buying the rickshaw, losing the rickshaw and is about how life has killed his idealistic dreams. However, merely Xiangzis account can not be depended upon. The story of Xiangzis loss of hope is told through two competing narratives. There is another narrator besides Xiangzi that every now and then gives us glimpses of the fact that the Hu Niu at the centre of all of Xiangzis lamentations is not completely real. Throughout Xiangzis struggles, the one character that we cannot get away from is Hu Niu, even though a pure account of her inner thoughts hardly ever surfaces. The importance of her role in this novel may seem somewhat belittled by the fact that every image we get of her character is through Xiangzis eyes. To work against Xiangzis bias, the reader must delve deeper under the surface n arratives through which to form ones own version of the original Hu Niu. We see very little of a non-Xiangzi-influenced, neutral narrators Hu Niu. And if we did rely on Xiangzis mind to tell us the whole story and all its underlying events, we would be cheating ourselves. For a thorough view of Hu Niu, Xiangzis version must be rounded out by our own analysis. The reason for this is that there is always a story unfolding that Xiangzi simply does not understand; there is a woman in this story that Xiangzi does not recognise. How reliable is Xiangzis explanation of the story? We should consider how reliable Xiangzis explanation is of the world at large. Xiangzis views of himself and the environment surrounding him occasionally seem ridiculously upside down. Having arrived in Beijing from the countryside at age 18, he has no education and is merely somewhat street smart. Being physically strong, and possessing characteristics like passion, honesty, righteousness , he is extremely self-righteous and self-confident. Through the narrators descriptions of Xiangzis arrogance, it helps us see that his views of himself are horribly distorted by his ego. Once he had grown into his body by his 20s, he became tall, strong, broad-shouldered and big-footed (5). He thought of himself as the best at what he did. We further see Xiangzis vanity in the fact that he goes as far as to smile at himself whenever he looks in the mirror; he is that satisfied with himself. He is so confident in his strength to be able to conquer everything that he never likes or bothers to talk with others or discuss anything with fellow rickshaw pullers. Even when he encounters something unlucky, he still believes that he would find a way out of it and would not be easily cheated or defeated because of his strength. All this narcissism we see in Xiangzi is a completely contradictory view to what we as bystanders think of him when we regard Xiangzi. We see on his face a particularly lurid scar, courtesy of a mule (5). This scar is long and large and a quite noticeable flaw on his face. Quickly, we begin to see that this scar is representative of more inherent character flaws, something more innate in Xiangzi that contributes to his eventual downfall. One of these flaws is his ego. Even though we see this gaping imperfection on his face, Xiangzis love for it remains the same as his love for his body, blind and excessive. He sees his face as also possessing tough strength just like his face (5). He essentially regards his face as another extension of one of his limbs; as long as his four limbs are strong, his face is also strong and noble. In actuality, Xiangzis scar attests to his short-sightedness. We sense that there is a feeling of mockery in the narrators detached statement that Xiangzi believes relying on only his []intelligence[] and exertions were enough to realize his ambitions (4). Another flaw is Xiangzis weakness for compliments, also a testament to his  vanity. He feels particularly important, for instance, when his impressive height requires him to duck his head when he passes through a doorway (11). Also, when no rickshaw puller is willing to risk going to Qing Hua University for fear of the warlord soldiers, all someone has to do is call Xiangzi a Big Boy and he promptly decides he would go, as though his strength could certainly prevent any danger from befalling him. This flattery of Big Boy, and the fact that the payer of the compliment was a short-of-bodybaldhead to whom Xiangzi felt significantly superior, led to the demise of Xiangzis first rickshaw. He had felt invincible. Xiangzis character flaw is also seen in his stubbornness. He is stubborn about not letting go of his money for medicine when he falls ill (9). He is stubborn about never needing a helping hand from anyone or anything. He deems himself to be so great that, depending only on his strength, he believes he would be able to escape from the evil cycle that is the life of a rickshaw-puller. This said cycle comprises the rickshaw man being forever doomed to pull a rickshaw his entire life, be frequently susceptible to injury, ultimately grow old, become chronically ill, and, unable to run any longer, one day fall down in the middle of the streets and die. Xiangzi is mulish about the fact that he could beat the system without anyones assistance if only he just stays away from distractions. This brings us to his ultimate stubbornness, which is about the disastrous distraction that is Hu Niu. As a result of seeing Xiangzis impressions of himself, we are wary of the validity of the image of Hu Niu Xiangzi projects through his narration. In knowing how traditional his views are and how biased he is against women of power, it is immediately evident how distorted his vision is of Hu Niu. As readers, we can see that his life takes a favourable turn when he meets Hu Niu. Even if we did contemplate her through Xiangzis prejudiced eyes, we can still see how useful and capable a person she is. This woman knows about life. We value her authority, and Old Master Liu values her authority and did not want to see her married and gone , but Xiangzi seems fundamentally incapable of seeing anything positive in her capabilities. In his mind, her intelligence translates into shrewdness, and her ability to manage and  organize translates into manipulation. What is more, he refuses to see that Hu Niu really cares for him. He rejects the possibility that, if only he would listen to Hu Nius advice, he could escape the rickshaw pullers horrible lifecycle. His stupidity is so blinding that he attributes his decline to the existence of Hu Niu, when in actuality his own stupidity is the very trait that causes his demise. Xiangzis closed-mindedness makes him unable to understand others motives, locking him in, and causing him to see everything from only his own point of view. Xiangzi does not have the intelligence or foresight to see the Hu Niu that readers see, or the fact that Hu Niu is his finest chance at a better life. Worse, he actually thinks Hu Niu will be the death of him. Every time she takes something into her own hands or solves a problem a problem from which Xiangzi would always run away, besides he would believe that he has suffered another wrong because he cannot stand being under her control (140-144). We consider Hu Nius economic sense to be sensible and her logic to be a good way to extract Xiangzi from his dreary existence. She has sensed that his personality could doom him to toil all his life (149). But she tells him outright that even though he may have his plans to sweat away his entire life, she has her plans to change that (149). And her plans for him consist of the hope that he will not need to pull a rickshaw anymore, not have to stink with sweat, and can get out of a dead-end occupation. Xiangzi, however, does not see that using keen business practices instead could lead quicker to a better life. All he wants is to painstakingly make money cent by cent through blood and sweat and buy his rickshaw; he does not know there could be any other ways to live. Hu Niu knows what must be done to help Xiangzi escape misfortune. She tells Xiangzi explicitly that she will take care of [him]; but all he wants to do is escape (83). To be sure, Hu Nius effort to end Xiangzis life as a rickshaw puller is partly due to the act that she does not want to be the wife of a poor rickshaw man (158). She regards herself as someone significantly more elegant than those living in the mixed courtyard. The thought that she could lose everything on Xiangzis account makes her momentarily almost regretful of marrying him (158). Nevertheless, these thoughts were only temporary  lapses in her mind, for she truly is in love with Xiangzi. She likens the happiness she feels being married to Xiangzi as feeling like her entire body was a big red flower blossoming warmly, fragrantly, beneath the rays of the sun (158). Inside, she knows that even if Xiangzi spends his whole life pulling a rickshaw, or if even he were reduced to begging, she would still never leave him; she would stay with him forever (158). Hu Niu tells Xiangzi of her love for him over and over: I think about you all the time. I love you. Ill take care of you (83), I know youre ambitious but you ought to realise that I really love you, too (156). But Xiangzi ignores it all. He is contemptuous of her behaviour and begrudges Hu Nius money (152). He does not want to think about how unmanly it is to be using his wifes money to buy a rickshaw (148). Hu Niu is scrupulous in her care for Xiangzi. She is not gentle by nature like Xiao Fuzi, so she does not know how to sweetly cajole him when speaking, especially if she is already anxious over him. When she tells Xiangzi that she still has four hundred dollars left after they marry and prods him to relax a little and enjoy life because he pull[s] a rickshaw and stink[s] of sweat all year long, it comes out sounding near to an order (148). But it is clear that her heart is not unkind and her intentions are good. Stubbornly, Xiangzi only sees the attention and concern that Hu Niu showers him as her attempts to fatten him up like a cow so as to better squeeze the milk out of him (152). We witness the fact that Hu Niu would very much like to have a quality family life with Xiangzi and hopes for Xiangzi to have a better life than that of a rickshaw pullers. She is undeniably calculating in deciding to approach her father, despite their fight, in order to get a firmer grip on Old Lius money. But this is so she would then be able to find Xiangzi a better job (157). She believes that Xiangzi has ideal traits of strength, diligence and frugality and sees in him potential for greater success if only he would let go of his death grip on the desire to only pull a rickshaw. But because Xiangzi has been a child of misfortune and knew what deep poverty was (152), he is unshakable in his belief that only hard physical labour is the solution to anything. Without much life experience (other than that of pulling a rickshaw), Xiangzi does not know any better. By ignoring the potential of Hu Nius abilities, he is  doomed to stay in the disastrous cycle. By looking beyond Xiangzis prejudiced criticisms of Hu Niu, we get a much most realistic view of this woman. Indeed, we even feel sorry for her. When she thinks of the joy of being married to Xiangzi, it is a fascination for her that she could not even speak of (158). We as readers, however, read almost in the same breath of Xiangzis hatred for her. While she wants to promenade with Xiangzi and show off the happiness of her marriage, Xiangzi, meanwhile, finds walking about with any woman in tow to be a disgraceful business, much less someone he abhorred as much as Hu Niu (146). This sort of ingrained thinking Xiangzi cannot change. Our sympathy for Hu Niu stems from the fact that her attempts to loosen his attitude and alter his mindset were ill-fated from the beginning. Xiangzis palpable narrow-mindedness permeates the entire novel. When he comes to the realization that his body wasnt as strong as it had been, he attributes it to the fact that Hu Niu, the bloodsucking monster, has sucked away his virility (205). It is never even a consideration that his age and the major bouts of illness could be the reasons for his inability to run as fast as before. Societal traditions have also embedded in him preconceptions about women like Hu Niu, whose every movewas like that of a woman who had been married for a long time (145) and chauvinism that a woman who is quick, experienced, and had an air of self-confidence is conversely not worthy of respect. Ironically, the more obsessively Xiangzi portrays to us the evil Hu Niu that he wants us to see, the more clearly we see the Hu Niu that is not shown through Xiangzis narrative. A thought that perfectly captures the irrationality and absurdity of Xiangzis mind is when Hu Niu poses to him the question, Between the two of us, who should listen to who? (149). This is a loaded question that triggers much thought. Despite the tenacity of Xiangzis incessant commentary, we do not come to side with him in formulating our answer to that question. On the contrary, we have gathered every evidence in each situation to believe that Hu Niu was the key to Xiangzis chance at breaking the cycle. Xiangzi is the only one who does not  see this and it is to his own immense detriment. His many character flaws are revealed in his enormous ego, stubbornness, shortsightedness, and staunch mistrust of others advice, especially advice from women. His prejudice against Hu Niu has been particularly hardened by societal beliefs and the traditional stigma that follows sharp and able women. Xiangzi is trapped in the blindness of his prejudice and remains perpetually unable to see and hear the Hu Niu that we ultimately comprehend. Ignoring Hu Nius help, support and advice, we watch with disappearing sympathy as Xiangzis hurtled towards the expected end of a rickshaw-pullers life cycle.

A Small, Good Thing, by Raymond Carver Essay -- Raymond Carver

The short story, "A Small, Good Thing" by Raymond Carver tells of two American parents dealing with their son's hospitalization and death as the result of a hit-and-run car accident. The insensitive actions of their local baker add to their anger and confusion, yet by the end of the story, leave them with a sense of optimism and strength. With such content, Carver runs the risk of coming across as sentimental; however, this is not the case, and the anguish of the parents and their shock at the situation is expressed with dignity and understatement. It is a story with a broad appeal: the simple prose makes it accessible to a wide audience, while the complex themes and issues make it appealing to the educated reader. Written in Carver's characteristically minimalist style, the story poignantly evokes not only the trauma of the death of a child, but also the breakdown of communication and empathy in society. The plain and direct narrative style suits the content, conveying the lack of c ommunication that is central to the narrative - between the parents, between the hospital staff, and with the baker. Critically, it is generally considered one of Carver's strongest short stories. It is a tale of isolation and of grief, but also of hope, and, with its fluid, pared-down style, clearly demonstrates why Carver is widely regarded as one of the greatest writers of the late 20th century. On the surface, the story of A Small, Good Thing is simple and universal. Thirty-three-year-old Ann Weiss orders a cake for her son's Scotty's eighth birthday and is a little put off by the baker's cold attitude - "(he) was not jolly. There were no pleasantries between them, just the minimum exchange of words, the necessary information." However, she soo... ...- emotional yet not melodramatic; sparsely written yet still complex; a human story which explores the arbitrary nature of fate. The writing style is fresh and invigorating; the characters well-drawn, the narrative driving, the themes thought-provoking. While some readers are likely to be frustrated by the limited exposition and the abruptness of the actions, most could be expected to find it well worth their attention. A Small, Good Thing has become a minimalist classic, and a close reading should clearly demonstrate why Carver is regarded as one of the strongest short-story writers in recent times.

A Time of Change in the Market Revolution Essay

1815 to 1860 was a crucial time for American commerce and urbanization that not only had strong economic influences, but also altered social and political perspectives. This time period, known as the Market Revolution, stemmed largely from the advancement in technology which led to transportation improvements and the building of railroads. Banks also contributed to the growing economy by increasing economic input and providing loans to merchants, manufacturers, and farmers. The rapid expansion of commerce and transportation had profound effects on American individuals socio-economic goals; a sense of self-confidence and domestic ideology surfaced, perpetuating westward expansion. Along with the spread of urbanization came the circulation of literary publications that fostered the spread of popular opinions; this eventually became an essential component to the many reform movements ultimately caused by the Market Revolution. All of these factors contributed to the republican ideal of individual freedom. Although the Market Revolution promoted economic and social growth through the development of technology and industry, it also led to actions threatening to republican liberties like equality and the inherent rights of man. Concerns of tyranny and disregard to the American Constitution caused many to focus on preserving the American republic through reform movements. The main driving factor of the reform movements that took place following the Market Revolution was the obscurity of republican values. Despite the positive influences the Market Revolution had on quality of life and transportation, many Americans feared the corruption of their individual liberties. They had proper reason to believe that this would be an occurrence caused by the unbalanced power that was established during the Market Revolution. One example of this unbalance was the increasing power of banks, more specifically addressed by Andrew Jackson when he vetoed the Second Bank of the United States. He asserts that the monopolized bank system undermines the rights of ordinary people because it establishes significant distinctions between classes where the upper class holds the power and dominates over the lower class. In a way, he attempts to reform the government-established powers instilled by the Second Bank of the United States by voicing how it is an abuse of power and limits economic opportunity for ordinary people. In addition to the unbalanced power created by the banks, a prominent deterrent from republican autonomy was the inequality that this instability of power caused for individual Americans. The rapid expansion of agriculture and population corresponded to the growth of slavery, which is the most pronounced example of the inequality America experienced during and after the Market Revolution. Slavery was seen by many as a direct violation of the Constitution and the inherent rights of man, which defy republican values. In the Republican National Platform, Abraham Lincoln brings to light that the inequality of slavery threatens national sovereignty, â€Å"That the maintenance of the principles promulgated in the Declaration of Independence and embodied in the Federal Constitution, †¦ is essential to the preservation of our Republican institutions; and that the Federal Constitution, the Rights of States, and the Union of the States, must and shall be preserved.† A nationalistic togetherness, while still maintaining individual freedom, is eminent in establishing and fulfilling republic ideology. Slavery was a direct violation of man’s inalienable rights, and therefore many abolitionist movements took place in order to reform the corrupt nation. Acts of slavery and other injustices initiated by the Market Revolution that defied republican values were identified as needing reform, in William H. Seward’s speech in 1855 he said, â€Å"We must restore the demoralized virtue of the nation. We must restore the principle of equality among the members of the State –the principle of the sacredness of the absolute and inherent rights of man.† The emerging Democratic party was host to many of the promoters of personal reform and social problems, while the Whig party advocated the reform of moralism and state-sponsored entrepreneurship. One of the initial influences of the reform movements was the moral mending that was deemed necessary by Protestants in order to overcome the sins occurring in society, and enact a sense of righteousness. These ideas of self-virtue and societal justice were reflected in the Second Great Awakening and the Temperance movement in the early 1800’s. The Second Great Awakening was a religious revival that had a strong influence on women, giving them a voice in society and the ability to make an impact for the salvation of American values. The Temperance movement had a similar purpose, to promote self-perfection and eliminate the many sins that became prominent in society during the Market Revolution. The movement focused on alcohol abuse and sexual sin, and although it bolstered self improvement for many individuals, a main impact of both the Temperance movement and the Second Great Awakening was the eminent duty of women to speak out against controversial happenings. Both of these movements had strong positive effects on the preservation of the republic because they fostered public regard to individual goodness, which in turn led to other reform movements and the ability for both women and men to speak out against injustices. Both women’s rights and slaves rights were distinguished issues that violated the equality of the republic, and therefore certain groups sought reform these corrupt aspects of American society. In the 1830’s, the abolitionist movement was initiated in an attempt to dissolve the sin of slavery. Although abolition became the source of immense controversy and even violence, the movement against slavery allowed slaves like Robert Glenn and Frederick Douglass to share their stories in an attempt to bring to light the corruption taking place in America. These movements did in fact help persuade many groups of people, mostly Democrats, of the Constitutional and moral violations that slavery inhibits. However, westward expansion and distinct divisions between the nation made it difficult to prevent the spread of slavery. Despite the fact that abolitionist movements did not have immediate effects on the eradication of slavery, it did open doors for public opinion and womens righ ts. In 1848, Elizabeth Cady Stanton and Lucretia Mott spoke out at the Seneca Falls Convention against the unequal status of women and how it reflects tyranny rather than the individual liberties of a republic. They emphasize the main point of both slavery and women’s rights reformations, â€Å"The world has never yet seen a truly great and virtuous nation, because in the degradation of woman the very fountains of life are poisoned at their source.† These movements did impact the protection of republicanism through the expression of activists who exposed the exploitation and inequality occurring due to slavery and unbalanced privileges of women. The Market Revolution had a domino effect on the fabric of the republic. It propelled economic growth and industrial expansion which then perpetuated unbalanced power within the government. This obscured the political values of individuals and brought about such a dramatic shift in thinking regarding opportunity and personal liberties that many people were concerned about the loss of republicanism. Members of the public like the Grimke sisters, as well as members of the government like Andrew Jackson, identified the injustices of inequality that were caused by the Market Revolution and felt as though reform was necessary to preserve the republic. The reform movements that took place, such as the Second Great Awakening and the abolitionist movement, exposed the pollution of republican ideals like individual freedom and egalitarianism. Although these messages were controversial between the sectional division of the North and South, reform movements still established a voice for the republic and eventually managed to preserve the prominent aspects of the republic. ——————————————– [ 1 ].

The Computer Technology

Computers are capable of doing more things every year. There are many advantages to knowing how to use a computer, and it is important that everyone know how to use them properly. Using the information I have gathered, and my own knowledge from my 12 years of computer experience, I will explain the many advantages of owning a computer and knowing how to use a PC and I will attempt to explain why you should purchase a computer and learn how to use one properly. Webster's New World Compact Dictionary defines a computer as â€Å"an electronic machine that performs rapid, complex calculations or compiles and correlates data† (â€Å"Computer. ). While this definition gives one a very narrow view of what a computer is capable of doing, it does describe the basic ideas of what I will expand upon. We have been living through an age of computers for a short while now and there are already many people world wide that are computer literate. According to Using Computers: A Gateway to Information World Wide Web Edition, over 250 million Personal Computers (PC's) were in use by 1995, and one out of every three homes had a PC (Shelly, Cashman,& Waggoner, 138). Computers are easy to use when you know how they work and what the parts are. All computers perform the four basic operations of the information processing cycle: input, process, output, and storage. Data, any kind of raw facts, is required for the processing cycle to occur. Data is processed into useful information by the computer hardware. Most computer systems consist of a monitor, a system unit which contains the Central Processing Unit (CPU), a floppy-disk drive, a CD-ROM drive, speakers, a keyboard, a mouse, and a printer. Each component takes a part in one of the four operations. The keyboard and mouse are input devices that a person uses to enter data into the computer. From there the data goes to the system unit where it is processed into useful information the computer can understand and work with. Next the processed data can be sent to storage devices or to output devices. Normally output is sent to the monitor and stored on the hard-disk or to a floppy-disk located internal of the system unit. Output can also be printed out through the printer, or can be played through the speakers as sound depending on the form it takes after it is processed. Once you have grasped a basic understanding of the basic parts and operations of a computer, you can soon discover what you can do with computers to make life easier and more enjoyable. Being computer literate allows you to use many powerful software applications and utilities to do work for school, business, or pleasure. Microsoft is the current leading producer of many of these applications and utilities. Microsoft produces software called operating systems that manage and regulate the information processing cycle. The oldest of these is MS-DOS, a single user system that uses typed commands to initiate tasks. Currently Microsoft has available operating systems that use visual cues such as icons to help enter data and run programs. These operating systems are ran under an environment called a Graphical User Interface (GUI's). Such operating systems include Windows 3. xx, Windows 95, and Windows NT Workstation. Windows 95 is geared more for use in the home for productivity and game playing whereas Windows NT is more business orientated. The article entitled â€Å"Mine, All Mine† in the June 5, 1995 issue of Time stated that 8 out of 10 PC's worldwide would not be able to start or run if it were not for Microsoft's operating systems like MS-DOS, Windows 95, and Windows NT (Elmer-Dewitt, 1995, p. 50). By no means has Microsoft limited itself to operating systems alone. Microsoft has also produced a software package called Microsoft Office that is very useful in creating reports, databases, spreadsheets, presentations, and other documents for school and work. Microsoft Office: Introductory Concepts and Techniques provides a detailed, step-by-step approach to the four programs included in Microsoft Office. Included in this package are Microsoft Word, Microsoft Excel, Microsoft Access, and Microsoft PowerPoint. Microsoft Word is a word processing program that makes creating professional looking documents such as announcements, resumes, letters, address books, and reports easy to do. Microsoft Excel, a spreadsheet program, has features for data organization, calculations, decision making, and graphing. It is very useful in making professional looking reports. Microsoft Access, a powerful database management system, is useful in creating and processing data in a database. Microsoft PowerPoint is â€Å". . a complete presentation graphics program that allows you to produce professional looking presentations† (Shelly, Cashman, & Vermaat, 2). PowerPoint is flexible enough so that you can create electronic presentations, overhead transparencies, or even 35mm slides. Microsoft also produces entertainment and reference programs. â€Å"Microsoft's Flight Simulator is one of the best selling PC games of all time† (Elmer-Dewitt, 50). Microsoft's Encarta is an electronic CD-ROM encyclopedia that makes for a fantastic alternative to 20 plus volume book encyclopedias. In fact, it is so popular, it outsells the Encyclopedia Britannica. These powerful business, productivity, and entertainment applications are just the beginning of what you can do with a PC. Knowing how to use the Internet will allow you access to a vast resource of facts, knowledge, information, and entertainment that can help you do work and have fun. According to Netscape Navigator 2 running under Windows 3. , â€Å"the Internet is a collection of networks, each of which is composed of a collection of smaller networks† (Shelly, Cashman, & Jordan, N2). Information can be sent over the Internet through communication lines in the form of graphics, sound, video, animation, and text. These forms of computer media are known as hypermedia. Hypermedia is accessed through hypertext links, which are pointers to the computer where the hypermedia is stored. The World Wide Web (WWW) is the collection of these hypertext links throughout the Internet. Each computer that contains hypermedia on the WWW is known as a Web site and has Web pages set up for users to access the hypermedia. Browsers such as Netscape allow people to â€Å"surf the net† and search for the hypermedia of their choice. There are millions of examples of hypermedia on the Internet. You can find art, photos, information on business, the government, and colleges, television schedules, movie reviews, music lyrics, online news and magazines, sport sights of all kinds, games, books, and thousands of other hypermedia on the WWW. You can send electronic mail (E-Mail), chat with other users around the world, buy airline, sports, and music tickets, and shop for a house or a car. All of this, and more, provides one with a limitless supply of information for research, business, entertainment, or other personal use. Online services such as America Online, Prodigy, or CompuServe make it even easier to access the power of the Internet. The Internet alone is almost reason enough to become computer literate, but there is still much more that computers can do. Knowing how to use a computer allows you to do a variety of things in several different ways. One of the most popular use for computers today is for playing video games. With a PC you can play card games, simulation games, sport games, strategy games, fighting games, and adventure games. Today's technology provides the ultimate experiences in color, graphics, sound, music, full motion video, animation, and 3D effects. Computers have also become increasingly useful in the music, film, and television industry. Computers can be used to compose music, create sound effects, create special effects, create 3D life-like animation, and add previous existing movie and TV footage into new programs, as seen in the movie Forrest Gump. All this and more can be done with computers. There is truly no time like the present to become computer literate. Computers will be doing even more things in the future and will become unavoidable. Purchasing and learning about a new PC now will help put PC's into the other two-thirds of the homes worldwide and make the transition into a computer age easier.

Butter Today essays

Butter Today essays Changing lifestyles have always influenced the approach to nutrition. Values and/or intimacy associated with the foods we as a society eat, have largely been washed away by a desire for easier and less time consuming preparations. We have traded in our larder for refrigerators and keep foods for lengths of time unimaginable 75 years ago. What we eat these days is unfortunately based on convenience. Inherently, ready-to-eat foods are what well reach for when we feel the need to fill the gap. Aspartame, monosodium glutamate, synthesized vitamins, and a host of preservatives are present in these foods to extend shelf life, increase flavour, suggest healthfulness, and increase the saleability to the demographics. With the trend of local, organic, and natural foods, now is the time to get back to basics by incorporating a fundamental nutritional building block a staple in every professional cooks kitchen at home and at work butter. Compared to margarine, butter serves more as an icon of a nation that sustains the family farm and the related values of this lifestyle. Certainly not as lucrative as margarine, butter is a simple natural product made from cream to which salt is often added for its preservative qualities. The cream is pasteurized and churned or shaken until it becomes semi-solid, at which point the buttermilk is separated. Fifteen to twenty percent of butter is milk solids and salt, held in an emulsion by naturally present lecithin, which also assists in the absorption of fat-soluble vitamins. Because of the presence of milk solids, butter has a refrigerated shelf life of up to one month, or at room temperature for a few hours. Slightly warmed butter is unmatched as a spread for flavour, but also for its naturally present unprocessed vitamins and other qualities. The most easily absorbed ...

Centromere Location and Chromosome Separation

Centromere Location and Chromosome Separation A centromere is a region on a chromosome that joins sister chromatids. Sister chromatids are double-stranded, replicated chromosomes that form during cell division. The primary function of the centromere is to serve as a place of attachment for spindle fibers  during cell division. The spindle apparatus elongates cells and separates chromosomes  to ensure that each new daughter cell has the correct number of chromosomes at the completion of mitosis and meiosis. The DNA in the centromere region of a chromosome is composed of tightly packed chromatin known as heterochromatin. Heterochromatin is very condensed and is therefore not transcribed. Due to its heterochromatin composition, the centromere region stains more darkly with dyes than the other regions of a chromosome. Key Takeaways Centromeres are regions on a chromosome that join sister chromatids whose primary function is for the attachment of spindle fibers in cell division.While centromeres are typically located in the central area of a chromosome, they can also be located near the mid-region or at a number of different positions on the chromosome.Specialized zones on centromeres called kinetochores attach the chromosomes to spindle fibers in prophase in mitosis.Kinetochores have protein complexes that generate kinetochore fibers. These fibers help to orient and separate chromosomes during cell division.In meiosis, in metaphase I, the centromeres of homologous chromosomes are oriented toward opposite cell poles while in meiosis II, spindle fibers extending from both cell poles attach to sister chromatids at their centromeres. Centromere Location A centromere is not always located in the central area of a chromosome. A chromosome is comprised of a short arm region (p arm) and a long arm region (q arm) that are connected by a centromere region. Centromeres may be located near the mid-region of a chromosome or at a number of positions along the chromosome. ​ Metacentric centromeres are located near the chromosome center.Submetacentric centromeres are non-centrally located so that one arm is longer than the other.Acrocentric centromeres are located near the end of a chromosome.Telocentric centromeres are found at the end or telomere region of a chromosome. The position of the centromere is readily observable in a human karyotype of homologous chromosomes. Chromosome 1 is an example of a metacentric centromere, chromosome 5 is an example of a submetacentric centromere, and chromosome 13 is an example of an acrocentric centromere. Chromosome Segregation in Mitosis Prior to the start of mitosis, the cell enters a stage known as interphase where it replicates its DNA in preparation for cell division. Sister chromatids are formed that are joined at their centromeres.In prophase of mitosis, specialized regions on centromeres called kinetochores attach chromosomes to spindle polar fibers. Kinetochores are composed of a number of protein complexes that generate kinetochore fibers, which attach to spindle fibers. These fibers help to manipulate and separate chromosomes during cell division.During metaphase, chromosomes are held at the metaphase plate by the equal forces of the polar fibers pushing on the centromeres.During anaphase, paired centromeres in each distinct chromosome begin to move apart as daughter chromosomes are pulled centromere first toward opposite ends of the cell.During telophase, newly formed nuclei enclose separated daughter chromosomes. After cytokinesis (division of the cytoplasm), two distinct daughter cells are formed. Chromosome Segregation in Meiosis In meiosis, a cell goes through two stages of the dividing process. These stages are meiosis I and meiosis II. During metaphase I, the centromeres of homologous chromosomes are oriented toward opposite cell poles. This means that homologous chromosomes will attach at their centromere regions to spindle fibers extending from only one of the two cell poles.When spindle fibers shorten during anaphase I, homologous chromosomes are pulled toward opposite cell poles but sister chromatids remain together.In meiosis II, spindle fibers extending from both cell poles attach to sister chromatids at their centromeres. Sister chromatids are separated in anaphase II when spindle fibers pull them toward opposite poles. Meiosis results in the division, separation, and distribution of chromosomes among four new daughter cells. Each cell is haploid, containing only half the number of chromosomes as the original cell. Centromere Anomalies Centromeres play an important role by participating in the separation process for chromosomes. Their structure however, can make them possible sites for chromosome rearrangements. Keeping the integrity of centromeres intact is thus an important job for the cell. Centromere anomalies have been linked to various diseases like cancer.

The Registration Statement (form s-1) Essay Example | Topics and Well Written Essays - 250 words

The Registration Statement (form s-1) - Essay Example From this perspective, the registration statement form successfully takes an enterprise â€Å"off the shelf† and into a certain market officially (Miller 506). When the Security Act of 1933 takes a business off the shelf, it normally offers them a base prospectus and supplement for a deeper understanding of public trading. Even though the goal of the 1933 Security Act was to allow a prospective procurement, it is not realized all the time. I believe this unsuccessful aspect of the law is brought about by the complicated nature of the registration statement. A business needs to be able to make a logical deduction bent on reliable data, which registration requirements included in the registration statement form often constraint. For instance, an issuer might be unwilling to engage true weaknesses in an activity. As a result, he or she uses the complicated registration statement form to delay the process while adhering to the law theoretically (Miller

ICT AND LITERACY Essay Example | Topics and Well Written Essays - 2750 words

ICT AND LITERACY - Essay Example rofound impact on our education, society and economy .But, teachers are not being well informed on ICT field as in contrast happens with the young pupils, considered as â€Å"digital natives†. Both teachers and pupils have to be taught to use the above devices and retrieve the appropriate information from the suitable web sites. The impact of technology on human lives will surely increase in times to come. The dependence of human race on technology is increasing at a terrific pace. Technology is no more meant for the ones who hold a degree of it like the software engineers and technicians, etc. The arena of technology use has penetrated to the common people segment also. Whether it is about withdrawal of money from an ATM, net banking, or reading voice messages on the telephone, technology has its presence everywhere. Thus, it becomes rather necessary to make the world population technologically literate. This will provide ease to the people to work and understanding the working in this rather technological world of today. Thus, the importance of ICT in literacy not is denied (Alan Rodgers, 2002). ICT has proved to be a huge success in value addition to students in every phase of learning and for every age group, be it children or adults, ICT offers learning advantages to all of them and can be used to provide learning in any discipline. Though, it is important to note that the ICT technologies have to be customized in order to suit the requirements of learners. Accepting the fact that being educated and adapting to today’s school and social needs, in my perspective, constitutes the major challenge of any time and the characteristic feature of the literate citizen in order to be considered productive and useful and not marginalized. And the current challenge regards information and communication technologies (ICT) that play an essential role in supporting daily life in todays digital society. They are used at school, at work, in day-to-day relationships, in
