Natural gas - Essay Example ) published a World Energy Outlook report in the year 2011 in which, the production of natural gas was estimated to increase by 50 per cent over the next two and a half decades. The report said, â€Å"Natural gas displaces coal and to a lesser extent oil, driving down emissions, but it also displaces some nuclear power, pushing up emissions. This puts emissions on a long-term trajectory consistent with stabilizing the concentration of greenhouse gases in the atmosphere at around 650 parts per million CO2 equivalent, suggesting a long-term temperature rise of over 3.5 [degrees Celsius]† (â€Å"Gas is not†). While a range of opinions exist for and against natural gas, it is overall a good source of energy. Natural gas is a good source of energy not only because it is in abundance in the US, but also because it can be transported affordably. Natural gas is a clean energy alternative because the process of its burning is cleaner compared to other fossil fuels. While burning, natural gas does not emit high amount of such harmful emissions as carbon dioxide, nitrous oxide, or carbon monoxide. Burning of natural gas also does not produce any particulates or ash. Although natural gas is not as clean as solar energy or wind energy, yet it can be considered as a stop-gap energy alternative because of its cost-effectiveness, abundance, and simplicity of use while the society transits to other sources of energy. The amount of carbon released into the atmosphere by natural gas is half as much as the amount that is released as a result of burning of coal. The US provides evidence of a success story as emissions declined to a 20-year low in the start of the year 2012. Although the decline in emiss ions can also be attributed to certain other factors like a shift to renewables and energy efficiency, the decline was at least, in part, because of a transition from the burning of coal to the use of shale gas. Similarly, â€Å"In countries like  Poland  and  China  where there is heavy

Home-Style Cookies Essay Example for Free

Home-Style Cookies Essay In this case study, the focus revolves around the Lew Mark Baking Company. The Lew-Mark Baking Company according to the case study is from a small town in western New York. Lew-mark Baking company operates in New York and New Jersey. It employs around 200 workers in a mainly blue collar, informal atmosphere. In my paper, I will answer several questions about operations for this company The Cookie Production Process When describing the cookie production process for Lew-mark baking, it is best described as using the batch processing system. The batch processing system can best be described as the execution of a series of programs (jobs) on a computer without human interaction. â€Å"Batch Processing is used when a moderate value of goods or services is desired, and it can handle a moderate variety of products and services† (Stevenson 2009, P 239). This method helps with quantity management because Lew mark only makes cookies according to demand. What are two ways that the company has increased productivity? Why did increasing the length of the ovens result in a faster output? One obvious way the company is increasing productivity is that it only makes cookies according to the demand. What ever order it receives from its distributor is what is made in the factory. This ensures that productivity is centered on the demand and time is not wasted baking products that might or might not sell. This is return, makes productivity quicker and more efficient. As mentioned above, the Batch processing system is a huge contributor to increasing productivity. Having two ovens also helps in speeding up productivity. Lengthen the ovens by 25 feet, increased the rate of production by allowing more cookies to be baked at the same time. Automating the Packing Although automating the packing of the cookies in normally a quicker and more efficient way of doing business, it is my opinion the Lew-mark baking Company is doing the right thing by employing local workers to do this job. It is vitally important to create good relationship within the community. This allows a company to have a stake in the community and thus foster good relationships with the local government, political officials and members of the community. Fostering these types of relationships can also be beneficial when it comes to future plans or expansions. Plus, the company has an obligation to the workers once they are employed with the company. As longs as profits and the bottom line are healthy, it should keep its commitment to the community. This would hold true in a small or large community. It is the obligation of industry to keep workforce engagement in tact. As long as industry is alive, some sort of human engagement is needed. What factors cause Lew-mark to carry minimal amounts of certain inventories? What benefits results from this policy? Obviously, the shelf life of perishables (cookies) keeps companies like Lew-Mark from storing big quantities of cookies in the warehouse. The longer these cookies stay in the warehouse, the lower the possibility of being sold. In reading the text, Stevenson’s goes into great detail about the Single Period Model of Inventory Management. This Model is used for ordering perishables and other items with limited useful life. It is interesting how Lew mark keeps a smaller inventory of labels. Their rationale is that the FDA label requirements change frequently and they do not wan to get stuck with labels they cannot use. Most of their inventory is ordered in small silos two or three times a week to save on ordering cost. This type of inventory control favors smaller businesses as long as they can forecast their production with accuracy. This allows Lew-mark to only buy what they use and use what they buy. If production decreases, they buy less. If production increases, they buy more. In the case of Lew-Mark Baking Company, this type of inventory control makes sense. Quality There are advantageous and disadvantages in using a non additive and non preservative approach to selling products. The advantage is that you can target a more health conscious audience to your product. With all the health disparities facing the country, you can carve out a specific audience for these types of products. On the flip side, you have to race against the clock because these non additives and non preservative shorten the life of these perishable items. In other words, your selling approach needs to be more progressive in its nature Conclusion In conclusion, the Lew-Mark Baking Company has an excellent product available to its consumers. Its pitch to sell non additive non preservative cookies targets and audience that is looking for this type of product. Because of its size, Lew-mark capitalizes in efficiency by using very tight inventory controls and production processes that keeps the company financially conscious and fiscally responsible. Its sensitivity to the community also brings morale responsibility that is noted by many members of the community and abroad. The Companies Strategy is to create a product that is desirable to the consumer and delivering that product in a way that makes the best business sense to its owners. As a consumer, I prefer quality in the form of a soft cookie. Understanding that the cookie has non and non preservatives is a plus.

Effectiveness of the Artificial Heart

Effectiveness of the Artificial Heart   Zeeshan Bhalwani   Artificial Heart The human heart is a wondrous structure of engineering. In the body of the average adult, the heart is the tenacious muscle that beats approximately 100,000 times each day, pumping blood through veins and arteries that extend upwards toward the brain and downwards towards the toes. It is no big surprise biomedical engineers have had a difficult time assembling a mechanical replica which is to function similarly as the heart and to keep patients with heart failure alive. Although comparative developments date back to the late 1940s, the first artificial heart was effectively implanted in a human was the Jarvik-7 in 1982, constructed by Willem Johan Kolff and Robert Jarvik (Strickland). The artificial heart is a prosthetic device that surgically replaces both ventricles and all valves of a heart used by adults with heart failure, and is becoming more prominent as innovation is advancing. Artificial hearts are normally used to delay the time to heart transplantation, or to indefinitely replace the heart in case heart transplantation is not possible. The most affluent impact of the artificial heart is that it saves over 5,000 lives every year (SynCardia). Additionally, this invention has had a beneficial impact on society because a fully functional artificial heart lowers the excessive need for heart transplants, since the demand for donor hearts surpasses supply. An example of someone who has been greatly assisted by the artificial heart is Pietro Zorzetto. He had an artificial heart in him for nearly four years, prior to his successful heart transplant on September 11, 2011 (Drumwright). Overall this device was of assistance to many people, but unfortunately there are also consequences that are turning up as progress is being made on the artificial heart. The consequences associated with the artificial heart are primarily unforeseen and bad, although little good can be seen. According to CardioWest, a certain artificial heart is designed to be attached to a power source outside the body through holes in the abdomen. These holes allow harmful bacteria getting inside the body which could potentially cause an infection. Additionally, since the mechanisms are so complex, they can malfunction in different ways. An artificial hearts pumping rate may not be exactly right, power may fail or parts altogether may stop working, which consequently would lead to sudden death. Another disadvantage of the artificial heart is that not all patients have a body size that allows the device to be implanted into the chest, making small people incapable of   receiving the device. As innovation is advancing and technology is progressing, these issues are beginning to diminish and new ways of developing the artificial heart are being introduced. According to MIT, the artificial heart is being enhanced to combine synthetic and biological materials as well as sensors and software to detect a patients level of exertion and adjust output accordingly. According to Carmat, a company concentrated on developing the latest bioprosthetic heart, it will comprise of two chambers each divided by a membrane which will hold hydraulic fluid. A motorized pump will move the fluid in and out of the chambers allowing the blood to flow through the chambers. The blood-facing side of the membrane is made of tissue procured from tissue that surrounds a cows heart, to make the device more biocompatible. The benefit of bioprosthetic hearts is they are not rejected by the bodys immune system. This is because they are made from metals and plastics, so the body does not recognize them as foreign and attack them in the same way it does with a manifold of living tissue. Furthermore, Pennsylvania State University researchers are developing a prosthetic hea rt powered by radio-frequency energy that is absorbed by the skin. Overall, these particular advancements are what will make the artificial heart sought-after. To conclude, heart failure is the leading cause of death all over the world. Most people die from the chambers of the heart failing to push enough blood through the body. A solution to heart failure was initially surfaced in the late 1960s. It had also required the advent of immunosuppressants. Around a decade later, the first successful artificial heart was developed and, the average survival rate of heart transplant patients increased to more than 5 years. The incessant furtherance of technology today will eventually lead to the creation of the perfect artificial heart and will be able to help every common man in need.

Deontologial Theory Essay -- essays research papers

ETHICS Deontological Theory Historically ethics was studied from a philosophical aspect and viewed as the science of morals. Ethics had been defined as the principles of moral conduct that govern our behavior. Our ethical behavior is developed from various factors, to include our environment, family and beliefs. The origins of ethics can be traced back to the fifth century, BC ( Banner, 1968, pg.67). Plato, Socrates and Aristotle are among the early teachers of ethics.   Ã‚  Ã‚  Ã‚  Ã‚  These teachers along with many other philosophers developed and taught numerous ethical theories based on their beliefs. Ethical theories that have evolved through the years include, but are not limited to:  §Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The Greek ethics of Plato, Socrates and Aristotle focused on moral virtues.  §Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The Christian ethics of St. Augustine focused on divine revelation.  §Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The consequential ethical theory of Bentham theorized that the consequences of one’s behavior are crucial when making moral decisions.  §Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The non-consequential ethics of Kant which viewed an individual’s duty and moral obligation as paramount when faced with an ethical challenge. Contemporary philosophers define ethics as a philosophical examination of the principles of right versus wrong, and view morality as the practice of these principles (Souryal, 1998, pg.17). The study of modern ethics and human behavior is a continuum of the examination of many of the same theories studied by earlier philosophers. One such theory is the deontological theory. This ethical theory is based an individual’s actions and not the consequences of the actions. Deontological is derived from the word deontos, the Greek word meaning duty or obligation. There are two sub-categories of the deontological theory. The â€Å"monistic† sub-category bases morality solely on one virtue. Examples of the monistic category of ethical theories are hedonism and Kant’s duty theory. In the theory of hedonism, pleasure is the only good, and in Kant’s theory on ethics, one’s duty or moral obligation is the sole virtue or value of goodness. The â€Å"multiple† sub-category of ethical theories has a minimum of two values of goodness, such as a woman marrying an intelligent and handsome man. The multiple values of goodness ... ...he human relations aspect of our jobs. Finally, as rational and intelligent individuals we must focus on the beneficial aspects of all-ethical theories and attempt to minimize the non-beneficial components of each theory. We must analyze the ethical dilemma and demonstrate the courage and moral virtue to apply the correct ethical theory that would result in the morally correct resolution to any given ethical dilemma. It is imperative that as rational and thinking human beings we consider the ramification of our actions and conclusively make the morally correct decision when faced with an ethical dilemma in law enforcement.

How far, and in what ways, do you agree that the story Essay

‘Hamlet’ is a revenge tragedy; a genre originally developed by plays such as ‘The Spanish Tragedy’ by Thomas Kyd from 1585-1590. The genre is characterized by the inclusion of death, murder, betrayal, madness, poison, surveillance and the supernatural in the narrative – themes that all frequently occur in ‘Hamlet’. However to what extent does the story of Polonius, Ophelia and Laertes conform to this idea of a revenge tragedy; and more broadly, how does the story of the family conform to the genre of tragedy as a whole? One issue is how to define a tragedy; Thomas Heywood wrote: â€Å"Comedies begin in trouble and end in peace; tragedies begin in calm and end in tempest†, ‘Apology for Actors’, 1612. By this definition, tragedy generally can be summarised as a sequence of events that lead to the destruction of the majority of its characters. In this sense, the story of Polonius and his family conforms to the basic skeleton of a tragedy – by the end of the play Polonius, Laertes and Ophelia are dead. However the family’s story does not conform as simply to other definitions of tragedy. ‘[Tragedy] would look with a sceptical eye at what was happening in the world around’, M. Mangan (1991). ‘Tragedy would look with a sceptical eye’ implies that tragedy has the role of both viewing and criticising society. This concept can be applied to Polonius, a character remarkably similar to Queen Elizabeth I’s spymaster, Sir Francis Walsingham. Shakespeare spent the majority of his life under Elizabeth’s rule; hence the Elizabeth’s gentry may have aided Shakespeare in creating his constructs. Polonius is characterized by his long, rambling speeches, for example in Act 2 Scene 2; ‘Either for tragedy, comedy, history, pastoral, pastorical-comical, historical-pastoral, tragic-historical, tragical-comical-historical-pastoral unlimited’ The absurd repetition of the words ‘tragedy’, ‘comedy’, ‘history’ and ‘pastoral’ emphasize the loquaciousness of Polonius, but is perhaps also mocking Sir Francis Walsingham. Shakespeare is crafting a stereotype that spymasters are loquacious, obsequious characters. Perhaps Shakespeare is criticising society; society does not require spymasters spawning insincerity and deceit. If so, Shakespeare is using satire as a tool to portray this viewpoint. Polonius may be used by Shakespeare as a means to act as such a ‘sceptical eye’ on society, conforming to Mangan’s concept of the relevance of tragedy in real life. Aristotle was a key figure in defining tragedy, and stated in his ‘Poetics’ that a typical tragedy consisted of a noble protagonist, with a hamartia (tragic flaw), whose peripeteia (reversal of fortune) is brought about by an anagnorisis (moment of recognition). However it would be unwise to assume that Aristotle’s ‘Poetics’, written in c. 335 BC would still be completely relevant to Shakespearean tragedy, written some two thousand years later. However several aspects of Aristotle’s tragedy can be applied to Polonius and his family. Polonius has his tragic flaw: his obsession with spying. He tells Reynaldo before departing to France to spy on Laertes: ‘By indirections find directions out’ (Act 2 Scene 1) Not only does this indicate his unnatural interest in his son’s affairs, so much that he is willing to send a spy to observe his sons possible hedonism in Paris; but it also shows that he is experienced as a spymaster. Such advice is most likely to be learned from several years of manipulating people to his advantage. Essentially what he is saying is the most direct method of finding the truth is through being indirect, which holds to be true as we see later in the play with Hamlet’s ‘The Mousetrap’; a play within a play which exposes Claudius’ villainy through indirect and subtle methods. Furthermore on the topic of hamartia – Laertes has his tragic flaw of overreaction; a stark contrast to Hamlet whose tragic flaw is procrastination. When asked by Claudius what he will do when Hamlet returns to Denmark to avenge his father in Act 4 Scene VII, he replies ‘To cut his throat i’ the church. ‘ This directly mirrors the church scene, where Claudius is vulnerable yet Hamlet refrains from acting out his revenge. This displays Laertes’ as a traditional revenger, willing to act, unlike Hamlet who considers the legitimacy of the ghost’s claims before even considering revenge. Laertes does not take much persuading from Claudius. However it is this over-willingness to act that is the cause of his death. In his rage at the death of both his father and sister, he plots with Claudius to kill Hamlet; a move which kills him as he himself is poisoned by the sword intended for Hamlet. Over-willingness to act is Laerte’s hamartia; and so Laertes also conforms to this tragic skeleton laid out by Aristotle. However perhaps more tragic, although not conforming to Aristotle’s works, is the question; why is Laertes so willing to act? His father was voyeuristic, deceitful and loquacious – he used Ophelia as a tool to gain favour with the king, and spied on Laertes to ensure his name was not tarnished. He was a far from noble man, his life summarised accurately by his death; behind an arras spying on someone. In this regard, it is questionable whether Laertes’ brashness in relation to revenge is justified. From the aspects of Polonius’ character seen in the play, it does not appear that he was a ‘good’ father; in fact he seems villainous at times – for example when he disallows Ophelia to express her love for Hamlet, then makes her feel to blame when Hamlet puts on his antic disposition. It is questionable whether Polonius ‘deserves’ to be avenged. Hamlet seems to simply shrug off the murder of Polonius, noting of what the little worth he was when referring him simply as ‘guts’. This could be seen as tragic, as the worthlessness of Polonius’ character implies that Laertes died for nothing. One explanation is that Laertes may have been inclined to act out revenge with such little persuasion due to the fact Polonius was all he and his sister had. Since Hamlet put on his antic disposition, Ophelia lacked a love interest, as did Laertes assuming he did not have a lover in Paris; moreover they were not allowed to have a love interest due to Polonius caring too much about his image than the wishes of his children. With no love interests, and apparently no motherly figure, they were left with no figure of authority but Polonius, which may be the cause for Laertes’ brash attitudes towards revenge. Also likely is the concept of family honour driving Laertes’ revenge, a concept which an Elizabethan audience may have empathised with. The death of Ophelia in a modern day sense is considered tragic, like any suspected suicide. However during Elizabethan times her death would be considered on a more religious basis; the priest comments on the ‘questionable’ nature of her death, and whether it would warrant a Christian burial. This is an example of how the definition of tragedy shifts over time; even Laertes does not seem as shaken by the announcement of his sister’s death compared to his fathers, perhaps due to the nature of her death. Ophelia’s death is considered a tragedy in a modern day sense, but at the time her death not so much tragic, but rather symbolised the death of innocence in the play, as part of the build up to the climatic deaths in the final act. However, Ophelia’s death is an example of how ‘Hamlet’ is able to transcend traditional ideas on tragedy, and can hold relevance to modern day interpretations of what is considered tragic. In the 21st century, a tragic event is where an individual or group suffers to a greater extent than they are perceived to deserve. It could be argued that however you spin the story of Polonius and his family, they will always conform to this modern interpretation of tragedy, as well as the traditional tragedy theorised by Aristotle. Ophelia is being perpetually commanded and ordered throughout the play by the significant characters in her life; first Laertes, when he displays his disapproval of her intimacy with Hamlet, and Polonius when he conducts his own ‘play within a play’, ordering her to talk to Hamlet while he observes behind an arras. She has little to no freedom, despite the fact she has ‘done nothing wrong’; unlike her brother who had enjoyed the ‘primrose path of dalliance’ while in Paris, and the voyeuristic indulgence of Polonius. The death of Ophelia to a modern audience is tragic, so in this sense the story of Polonius and his family is a tragedy. I agree that the story of Polonius and his family should be considered ‘a tragedy within a tragedy’. Their story contains many of the frequently occurring aspects of a tragedy; death, love, murder, revenge and surveillance. As well as this, the family conforms to the concept of a tragedy as laid out by Aristotle. Finally, the story of Polonius and his family conforms to what is considered tragic in the present, as the tragedy has transcended the period in which the play was written.

Binary oppositions of Male/Female in Wide Sargasso Sea Essay

The novel Wide Sargasso Sea is basically a contrast as well as shows similarities between main male and female characters of the novel. The Male of England vs. the Female of Caribbean is the focus of this essay. Both the characters play an important role in enhancing the themes, symbols and metaphors of the novel. No doubt, the writer of the novel Rhys has done a great job in explaining different psychological states of both the characters while putting them in different social situations. The first similarity between them is the search for security. In their entire lives they keep on searching for physical and mental securities. Antoinette wants it in the form of a man who can support him in many different ways and Rochester wants security in terms of finance and of the fulfillment of his lust. With security, they are in search of happiness also but the operational definition of happiness to both of them is completely different and which is the main crises of the novel. According to Rochester, happiness is in physical love and wealth while to Antoinette happiness is in being a protected woman. The main desire of Antoinette in the novel is being loved and respected but unfortunately her man is unable to satisfy her in that manner. He never tries to understand his wife and always wants her to follow what he says, regardless of the fact that she is a human being and trusts him to extent. Rochester is in a superiority complex because of his complexion and is under the impression that he’s superior to others because he belongs to England. Not only he himself is in superior complex, he wants to have an upper hand on Antoinette and associates her with inferiority because of her dirty childhood. This is a human nature that everyone likes his/her mother land and so in the case of the novel. The guy of England doesn’t like to live in Caribbean and the girl of Caribbean can’t adopt the culture of England. They not only love their places but also hate to live at each other’s†¦ Rochester feels insecure with the people of Caribbean and not feels comfortable living there. He is the man who has spent his early years in a developed country and can’t adjust to a landscape now. On the other side, Antoinette is under the impression that her man’s dry behavior is due to the fact that he has to live in a totally different environment and she is, to some extent, true as well. One of the very important similarities between both the characters is dependence. She is dependent on him for social and financial management. Being a lady, she has to have a man to secure her in every possible way while he’s dependent on her for sexually satisfying himself. He’s dependent in the context of wealth as well. Antoinette wants to dominant her fear (of childhood) through getting a life partner where Rochester wants a companion to satisfy his sexual desires. She goes through a miserable childhood and this is the cause of her psychological state that comes in the later part of the novel. In the novel, both of the main characters go through some type of mental disorder. Antoinette, being insecure to an extent that locks her in the room while Rochester experiences paranoia and thinks that his lady will leave him in that fearful and insecure place. The novel is tragic, not because it has a sad ending but because both of the characters are unsuccessful in achieving their targets. Not only they lead their lives miserably but they meet an unhappy and tragic end as well. Instead of becoming a lady of her man’s heart, she is supposed to become a slave and on the other hand Rochester is under the impression that his lady doesn’t love him at all and has no interest in living with him. Throughout the novel, both of them keep on expecting from each other but running after their own happiness and desires of lives. We see that they want to lead their lives according to their wishes. She doesn’t want to live in England while he hates Caribbean. We hardly see any element of compromise between them. They are less human in the sense that they give importance to their desires over people. But we have sympathy to both the characters also because this behavior of being selfish is due to the society. Her nature of being loved is due to her dark and unloved childhood while his obsession of money has excuses too. In a sense, both of them want happiness throughout the novel but meet a woeful end!
