Shah Jahan - Mughal Emperor of India
Shah Jahan - Mughal Emperor of India From the often chaotic and fratricidal court of Indias Mughal Empire sprang perhaps the worlds most beautiful and serene monument to love - the Taj Mahal.à Its designer was the Mughal emperor Shah Jahan himself, a complex man whose life ended in tragic circumstances. Early Life The child who would become Shah Jahan was born on March 4, 1592, in Lahore, now in Pakistan. His parents were Prince Jahangir and his wife Manmati, a Rajput princess who was called Bilquis Makani in the Mughal court. The baby was Jahangirs third son. He was named Ala Azad Abul Muzaffar Shahab ud-Din Muhammad Khurram, or Khurram for short. As a child, Khurram was a particular favorite of his grandfather, Emperor Akbar the Great, who personally oversaw the little princes education. Khurram studied warfare, the Koran, poetry, music, and other subjects suitable for a Mughal prince. In 1605, the 13-year-old prince refused to leave his grandfathers side as Akbar lay dying, despite the potential threat from his fathers rivals for the throne. Jahangir succeeded to the throne, after crushing an uprising led by one of his other sons, Khurrams half-brother. The incident brought Jahangir and Khurram closer; in 1607, the emperor awarded his third son the fiefdom of Hissar-Feroza, which court observers took to mean that 15-year-old Khurram was now the heir apparent. Also in 1607, Prince Khurram was engaged to marry Arjumand Banu Begum, the 14-year-old daughter of a Persian nobleman. Their wedding did not take place until five years later, and Khurram would marry two other women in the meantime, but Arjumand was his true love. She later became known as Mumtaz Mahal - The Chosen One of the Palace. Khurram dutifully sired a son by each of his other wives, and then neglected them almost entirely. He and Mumtaz Mahal had 14 children, seven of whom survived to adulthood. When descendants of the Lodi Empire rose up on the Deccan Plateau in 1617, Emperor Jahangir sent Prince Khurram to deal with the problem. The prince soon put down the rebellion, so his father granted him the name Shah Jahan, meaning Glory of the World. Their close relationship broke down, however, over court intrigues by Jahangirs Afghan wife, Nur Jahan, who wanted Shah Jahans youngest brother to be Jahangirs heir.à In 1622, with relations at their zenith, Shah Jahan went to war against his father. Jahangirs army defeated Shah Jahans after a four-year fight; the prince surrendered unconditionally. When Jahangir died just one year later, in 1627, Shah Jahan became the Emperor of Mughal India. Emperor Shah Jahan As soon as he took the throne, Shah Jahan ordered his stepmother Nur Jahan imprisoned and his half-brothers executed, in order to secure his seat. Shah Jahan faced challenges and uprisings all around the edges of his empire, as well. He proved equal to the challenges from Sikhs and Rajputs in the north and west, and from the Portuguese in Bengal. However, the death of his beloved Mumtaz Mahal in 1631 nearly shattered the emperor. Mumtaz died at the age of thirty-eight after giving birth to her 14th child, a girl named Gauhara Begum. At the time of her death, Mumtaz was in the Deccan with Shah Jahan on a military campaign, despite her condition. The distraught emperor reportedly went into seclusion for an entire yearà and was only coaxed out of mourning by his and Mumtazs eldest daughter, Jahanara Begum. Legend says that when he emerged, the forty-year-old emperors hair had turned white. He was determined to build his empress the most magnificent tomb the world had ever known. It took the next twenty years of his reign, but Shah Jahan planned, designed, and oversaw the construction of the Taj Mahal, the worlds most famous and beautiful mausoleum. Made of white marble inlaid with Jasper and agates, the Taj is decorated with Koranic verses in lovely calligraphy. The building occupied 20,000 workers over the course of two decades, including craftsmen from far-off Baghdad and Bukhara, and cost 32 million rupees. In the meantime, Shah Jahan began to rely increasingly on his son Aurangzeb, who proved an effective military leader and an Islamic fundamentalist from a young age. In 1636, Shah Jahan appointed him viceroy of the troublesome Deccan; Aurangzeb was just 18. Two years later, Shah Jahan and his sons took the city of Kandahar, now in Afghanistan, from the Safavid Empire. This sparked on-going strife with the Persians, who recaptured the city in 1649. Shah Jahan fell ill in 1658à and appointed his and Mumtaz Mahals eldest son Dara Shikoh as his regent. Daras three younger brothers immediately rose up against him and marched on the capital at Agra.à Aurangzeb defeated Dara and his other brothersà and took the throne. Shah Jahan then recovered from his illness, but Aurangzeb declared him unfit to rule and had him locked up in the Agra Fort for the rest of his life. Shah Jahan spent his last eight years gazing out the window at the Taj Mahal, attended by his daughter Jahanara Begum. On January 22, 1666, Shah Jahan died at the age of 74. He was interred in the Taj Mahal, beside his beloved Mumtaz Mahal.

The influence of music Essay Example | Topics and Well Written Essays - 500 words
The influence of music - Essay Example Specific attention shall be paid to some of the common genres as well. This paper shall seek to look at the different ways in which music influences the listenerââ¬â¢s behavior. Different genres shall be mentioned and the behaviour associated with each shall be studied. On the flipside, the extent to which the choice of music complements listener behavior shall also be explored. A) Message contained in the lyrics influences a listeners behavior. Rock and hip hop contain messages of a violent kind. The use of drugs in general and alcohol to be specific is a common theme. This is in turn carried on by the listeners especially the young impressionable type. Soul and blues are more sedate and advocate love not conflict. C) Generally, the mental disposition of listener influences behavior. Despite the dangerous level of sway that the factors in A and B above hold, the amount of control the listener has over their faculties is the principal determiner of general conduct. Responsible listeners are able to see through the messages and carry themselves out in ways that are good to the general

To what extent do David Hockney and Chuck Close adopt traditional and Dissertation
To what extent do David Hockney and Chuck Close adopt traditional and digital processes in their Fine Arts practice - Dissertation Example Therefore, it is important to understand how a piece of work becomes a piece of art, and to what purpose that label provides to society. One of the first tools that provided this narrowing of the gap between the artist and the crafter is the camera. Photographic art is defined by parameters that society has set in order to assign value to one photograph over another. However, people from all walks of life and with a variety of intentions have cameras and take photographs, some sharing aspects of artistic quality of those taken by people whose work is considered art. Therefore, it is sometimes difficult to create definitive separations between those who use the same types of equipment and create the same kinds of work. Two artists that can be used to discuss the development of digital art are Chuck Close and David Hockney. Chuck Close imitates the digital form, his paintings recreating the digital world through painstaking techniques that create startling realism. One of the finest ex amples of digital art that can be seen through the manipulation of photographic images is in the work of David Hockney. The narrative that is created through his form of collage he called ââ¬Ëjoinersââ¬â¢ creates a reflection of cubism, the individual pieces of the work creating a sense of communication. Defining Art The digital world is a place where the amateur has been given the opportunity to create work that is as expressive as the professional, artistic creations being made with the need for technical skills, at least in the way of tangible elements being put into the works, eliminated and replaced with user friendly tools. Most people have embraced the use of computer technologies, meaning that now almost anyone has the capacity to create art without having to brush paint, form clay, or construct true form. The virtual world is a malleable place which recreates the imagery of three dimension or allows for the manipulation of elements and forms. This means that not only the concept of a true artist is in contrast to a crafter has been permanently blurred, but it means that much of the physical needs of the artist can possibly be replaced with a medium that strips away the need for physical skill, replacing it with intellectually learned skills, the medium diminishing the need to know how to manipulate the real. A digital environment abstracts the fallibility of the human stroke against the canvas and replaces it with an opportunity for perfection. Creating art in a digital world can allow the artist to bypass some of the frustrations that can occur when the creation isnââ¬â¢t reflecting the vision so that the intent of the work can more easily and readily come through to the viewer. Digital art can also allow the artist to take what could not be rendered to perfect expression and refine it to reflect the intended vision. When the human mechanics can not create something that has the nuance that a digital work has, then the artist must consider t o the use of digital enhancement to create what is envisioned. The artist is given a broader number of tools in which to manipulate his expressions, those tools requiring a different type of technical knowledge that was not in previous history available. The artists skills are relevant in a different way, not through his or her expertise with simple tools, but with his or her ability to use common tools of the technical age. What will define the artist

Social And Natural Sciences - Essay Example A great contribution of positivism into philosophical and methodological explorative methods is considered further on the example of social and natural sciences. In sociology, positivism is the core paradigmatic methodology. Science and inquiry are two basic pillars of positivism. Still, it is very important to solve the major problem of social sciences, which concerns results finding on the basis of complex species research and study. The roots of Positivism can be traced in the French Enlightenment. The philosopher suggested combining natural sciences principles with social sciences. Comte claimed that religion was conquered by science. It was much important those times to refer to facts and laws, than to suppositions and considerations. Scientific knowledge is outlined by Comte in the following way: the stage of fictitious, metaphysical and scientific knowledge. The last stage of knowledge, scientific knowledge, is preferential for Comte. The development of all other stages, if su ccessfully implemented, would result in scientific knowledge emergence. These stages of knowledge can be also sought in Empiricism. This science is based on observable facts, claiming that logical and mathematical roots are in the background of the facts. The main principle of positivism should be also found in ââ¬Å"positiveâ⬠information, which can be obtained from a positive experience. A methodological paradigm of positivism consists of science and inquiry. An empirical exploration is of crucial importance for any science.à ... These stages of knowledge can be also sought in Empiricism. This science is based on observable facts, claiming that logical and mathematical roots are on the background of the facts. The main principle of positivism should be also found in ââ¬Å"positiveâ⬠information, which can be obtained from a positive experience. Therefore, a methodological paradigm of positivism consists of science and inquiry. An empirical exploration is of crucial importance for any science. Thus, from positivist perspective it can be claimed that social phenomena are not distributed in accordance with certain or specific types, where the members of these types are homogenous (Cassell, 2002). In other words, positivist vision or methodology implemented in social sciences is not relevant to the fullest extent. Sociological phenomena are of inhomogeneous nature. For example, a structure of any sociological object or phenomena cannot be considered in accordance with specific features or characteristics, w hich are relevant at all times. Moreover, social processes and generalizations cannot be characterized simultaneously in accordance with homogenous characteristics. For sociological sciences it is of crucial importance to formulate specific hypotheses focused on special sociological events or imagination. A development of sociological theory is one possible way to develop explanations concerning sociological events or objects. Therefore, positivism is often criticized as irrelevant methodology applied for social inquiry. Social science requires development of special approaches focused on ââ¬Å"contingency, heterogeneity, path-dependence, and particularity corresponding to the plasticity of

Tissue engineering for skin
Tissue engineering for skin TISSUE ENGINEERING OF THE SKIN (MECH 5510M) LITERATURE REVIEW SID: 200507638 ABSTRACT: This essay is a literature review on the tissue engineering for skin replacement, with regard to the clinical need, approaches various commercially-available products. Skin is undoubtedly crucial in the maintenance of the bodys internal balance also protecting externally. It gets severely compromised in burns, non-healing ulcers, reconstructive surgeries etc. bringing down the patients quality of life drastically. Tissue engineering is a more efficient approach than traditional skin grafting. It is a research area that is forever evolving, where researchers are always working towards one united goal, i.e. to develop in bulk quantities, a skin substitute that can be handled with less care, integrates faster with the bodys natural matrix and costs reasonable. INTRODUCTION: A lot of research has been undertaken in the past to realize that it is possible to generate skin by applying engineering techniques. This is done by growing skin at a faster rate than normal and in an artificial manner4. Skin is the largest most widely spread organ in the human body. Its role is to protect the bodys internal environment from harshness of the external conditions and restrict entry of microbes, by acting as a barrier4. Several situations diseases arise, due to which the skin gets irreparably damaged, thus requiring interventional help in restoring it back to health. Tissue engineering is the application of engineering techniques to develop biological substitutes1. Burns (acute) ulcers (chronic) are the most common conditions which require the replacement of skin. In developing countries (Fig 1)2,3, due to lack of knowledge on safety, a very high number of burns accidents occur every year, and mostly of fatal nature. The fatality is mainly due to pain, infection, loss of body fluids incapability of the body to self-regenerate large amounts of lost skin5. Thus, experimentation in this field was triggered. Many skin diseases, which lead to necrosis, pigmentation problems, also require engineered skin4. CLINICAL NEED FOR SKIN TISSUE ENGINEERING: In most incidents, both the epidermal and dermal layers require replacement. Conventionally, the treatment method involved skin grafting i.e. autologous (self) split-thickness and full-thickness grafting, where healthy skin was taken from other areas of the body and replaced at the injury site. Split-thickness (comprising of the epidermis a part of the dermis) grafting is not a logical method to use, when a large area of the body (>50%) is affected less healthy skin is available. But, it is todays gold standard approach6. Further trauma, due to grafting, can be painful to a patient who is already in a critical state. Also, scar formation post-operatively is another reason for its reduced usage. Full-thickness grafts are suitable to use when the burned area is less than 2% of the total area. These problems could be avoided if skin (of full or partial thickness) were grown artificially and substituted in the place of real skin6. LITERATURE REVIEW: The skin can be broadly divided into two layers i.e. the epidermis dermis. The epidermis is made up of several layers and may/may not consist of extra-cellular matrix (ECM). The layers from surface to deep are: cornified, granular, spinosal and basalar layers. The most commonly found cells here are the keratinocytes melanocytes. The dermis is constituted by GAGs proteins. Within the dermis, fibroblasts are most commonly found8. Several skin substitutes exist for wound coverage in tissue engineering4. It can be broadly divided into temporary and permanent skin substitutes. The table below (Table 1) is a list of all the material options available for skin replacement: Table 1: Temporary and Permanent Skin Substitutes8 Permanent tissue engineering of the skin can be broadly divided into three categories6, 8: Epidermal replacements Generally, using autologous keratinocyte sheets. Replaces only the epidermis, but ââ¬Å"take ratesâ⬠are very poor, suitable for superficial burn treatment only. Dermal replacements Replaces only the dermal layer. In most cases, it is applied along with an epidermal graft to improve ââ¬Å"take ratesâ⬠. Dermo-epidermal (bilayer skin) replacements Replaces both the epidermis and dermis. Suitable for full-thickness burns. Skin replacements have two main components i.e. cells and the scaffold. In wound coverage, three types of cells can be used autologous, allogenic or stem cells. Autologous (self) cell usage is the most preferred as it is easily accepted by the patients body does not need incite and anti-immune responses. Allogenic (donor) cells, if used directly can lead to the eventual rejection of the transplant. However, it is used in an acellular fashion, where the donor keratinocytes are removed prior to culturing9. Stem cells have trans-germal pluripotential properties are currently being researched for their poteintial application in skin engineering. Less information is obtained on keratinocyte stem cells. The suggested reason for their longevity is that KSC cycles very slowly and is resistant to mutations8. The type of biodegradable scaffold, either natural or synthetic permits cells to attach onto them and facilitate handling during transplantation6, 9. Rheinwald Green Experiment8: The experiment carried out in 1975 by Rheinwald and Green where human (autologous) keratinocytes were produced in-vitro, proved to be a breakthrough in this field and modified versions of this method are used nowadays. Extracted keratinocytes were allowed to form colonies on a plastic substrate. These colonies expanded to form a sheet. Stratifications arose as the daughter cells, usually at the centre, started multiplying vertically and a 12-cell layer was achieved. To increase the multiplicative capacity of keratinocytes, a feeder layer (comprising murine Swiss 3T3 lethally irradiated fibroblasts) mitogens were introduced to the culture. Epidermal Replacements: A small skin biopsy of the patient is harvested, which is cultured to produce a patch. The full-thickness biopsy of the patients skin is cut finely and enzymes are added to cause disaggregation of the skin into cells. A feeder layer, as mentioned previously, is used to culture these cells in culture flasks. To promote proliferation, epidermal growth factors, enzymes such as insulin, hydrocortisone, cholera-toxin and bovine serum are used. After colonies have been formed, trypsin is added. The KCs are cultured to confluence and later, the sheets are removed from the flasks (using dispase) for use8. The result of this method compared to the split-thickness gold standard is quite poor, as the dermal layer is missing and it depends upon the health of the dermis existing. Also, it is prone to scarring, takes too long, expensive, extremely fragile and has varying ââ¬Å"takeâ⬠rates6. Dermal Replacements: It was claimed, in 1952, that using only pure epidermal sheets, success would be lesser than compared to those with a dermis10. To accentuate the success of the epidermal transplantation, dermal replacements were constructed. A dermal replacement that covered the affected area with cryoprserved allogenic skin was used minus the epidermal layer was used11, 12. Also, an observation that allogenic keratinocytes elicited more anti-immune response than allogenic fibroblasts, was reported. To reconstruct the dermis, the two-stage Integra application is most widely used now13. This dermis functions as a scaffold for the attachment of keratinocytes and improves vascularization9. Burke et al (1981) developed a dermal replacement, where a collagen sponge was covered with a silastic layer (synthetic). The sponge behaves as a scaffold for the fibroblast cells. This technique was commercialized into a product (Integra Dermal Regeneration Template) 9, 14. A modification to this employed GAGs along with collagen, in the scaffold. Here, a precipitated mixture of bovine collagen fibres and a chondrotin-6-sulfate (GAG from shark cartilage) was freeze dried. This generated a collagen-GAG sponge scaffold, which had a mean pore size. Cross-linkage to strengthen the matrix was done using gluteraldehyde. Finally, the silastic layer was applied. This is available as a product; Integra Artificial Skin (Chamberlain and Yannas, 1999)9, 15. According to Heimbach et al (1988), this is most suitable for burns patients. The concept of using absorbable polymer scaffolds (synthetic) such as polyglactin 910 or polyglycolic acid was the next improvement in dermal replacements. Here, allogenic fibroblasts are enzymatically cultured and this culture is mounted on the polymer scaffold for integration). Due to this, an ECM consisting of collagen, growth factors, GAGs etc. is formed, which stays active even after it is frozen17. This was commercialized as Dermagraft 8, 16. Two-stage dermis application has shown proven results, and now clinical trials are being conducted to examine the applicability of one-stage dermis, such as Matriderm 6. The dermal replacements essentially require an epidermal covering. Dermo-Epidermal Replacements: These are available both as autologous or off-the-shelf products. In autologous DED replacements, both keratinocytes and fibroblasts are harvested from the patient and are added to the collagen-GAG scaffold. Cultivation of this in culture medium is for around four weeks. This is a more permanent solution 6, 18, 19. The first model of todays Apligraf was done by Bell et al (1979)20. DEDs use human keratinocytes fibroblast cells (allogenic) within a scaffold. Morphological studies after using Apligraf reported the presence of a well-defined epidermis, with all four layers, as in the natural skin, and seeded allogenic fibroblasts aligned in a normal manner within the collagen matrix 8, 21. COMMERCIALLY AVAILABLE PRODUCTS: CONCLUSION FUTURE AIMS: Tissue engineering of the skin was the first to be approved by the FDA has evolved a great deal, from the first application of only cultured keratinocytes to the use of biological skin substitutes. Research is still in-progress to develop skin in bulk quantities, mainly for burns patients, and to mimic all the mechanical and properties and functions of the natural skin. The state of the art results can be achieved now by using cultured keratinocyte cells with the dermal replacement, Integra, in full-thickness, small and clean wounds. This has shown optimal results in cosmesis and wound closure8. However, this branch of tissue engineering is still very much in a developing level. Studies to analyse how to reduce various risks in patients, who receive donor cells should be done. Also, a main difficulty is in getting the cells to attach to the dermis, post-transplantation. Burns patients are highly susceptible to various problems, thus there is a need for materials that present lower risk than animal/human materials. Mainly, it is ideal if the graft starts to behave like natural skin soon after grafting, which is possible only with rapid vascularization and cell implantation. Also, low expense of these products is extremely desirable. REFERENCES: Nerem R M. 1992. Tissue engineering in the USA. Medical Biological Engineering Computing, Vol 30, pp. CE8-CE 12.

Janies Wardrobe in Their Eyes Were Watching God :: essays research papers
In Their Eyes Were Watching God Janie goes through several marriages in her journey to seek love. As Janie's husbands change so does her wardrobe. Janie's different marriages are symbolized by her very different wardrobes. Janie's first marriage was to Logan Killicks when she was just a young girl at the age of seventeen. Janie?s wardrobe mainly consisted of aprons and work clothes. Logan was very demanding and controlling over Janie, he made her work in the field and cook all day. Most of her time was spent cooking and she almost always wore her apron. ?That made her feel the apron tied around her waist. She untied it and flung it on a low bush beside the road an walked on(page 32). Janie threw off her apron while she was leaving Logan, symbolizing how she was no longer under his control and she was now back on her journey for love. Jody Starks was Janie?s second husband and was even more controlling over Janie than Logan. Janie usually wore very nice designer dresses because Joe was the mayor of Eatonville and felt that the mayor?s wife had to wear the best. The dresses symbolize the control and arrogance of Joe, because he forced Janie to wear things she was not comfortable in just to show off their money. Joe also made Janie wear head rags to cover her hair after an incident in the store. ?This business of the head-rag irked her endlessly. But Jody was set on it. Her hair was NOT going to show in the store.? (page 55). The head rags symbolize not only the control of Janie like in her first marriage but it also shows the jealousy Jody has towards his wife and other men. Once Janie was an older woman in her forties she finally found the love of her life Tea Cakes. Tea Cakes soon became her third husband and has no comparison with the other two marriages. While married to Tea cakes Janie wore whatever she wanted because he was not controlling over her like in either of her other two marriages. Janie usually would wear overalls like Tea Cakes symbolizing how free and not under control she was. ?They don?t need to worry about me and my overhalls long as Ah still got nine hundred dollars in de bank. Tea Cake got me into wearing?

George Orwell ââ¬Å1984ââ¬Â Essay
In George Orwellââ¬â¢s ââ¬Å"1984â⬠, Winston Smith and Julia live in Oceania, where their actions become a subversive force that the ââ¬Å"Partyâ⬠must control. Oceania, located in Europe, represents a totalitarian society in its purest form during the 1940s. Many aspects of Wilsonââ¬â¢s and Juliaââ¬â¢s daily life in Oceania are monitored and controlled by the ââ¬Å"Party.â⬠From the telescreen to the thought police, every action is under constant surveillance. In order to rebel against Big Brother, Winston and Julia commit a series of crimes without knowing that Oââ¬â¢Brian, a member of the Inner Party, is watching them intently. Oââ¬â¢Brian then deceives Winston and Julia into believing that he is part of the revolutionary group called the Brotherhood. Winston and Juliaââ¬â¢s betrayal becomes inevitable after their capture because of the psychological supremacy of Oââ¬â¢Brian and the Party. Winstonââ¬â¢s physical and mental torture and brai nwashing by Oââ¬â¢Brian and the Ministry of Truth in the name of the Party is what ultimately leads to his psychological break down. Winstonââ¬â¢s rebellious character portrays him as a radical, who has the strength to defy the party and its principles. Winston and Julia secretly meet and it becomes apparent that she shares his rebellious ways. Learning that she has engaged in sexual acts with numerous Inner Party members, Winston finds hope. Winston and Julia, however, rebel against the Party for different reasons. Winston wants to end the harsh oppression of the party while Juliaââ¬â¢s rebellious acts are more self-centered. Winston first demonstrates his hatred of the Party and Big Brother when he writes in his diary ââ¬Å"DOWN WITH BIG BROTHERâ⬠. He knows at that very moment a camera might see the written words on the page. Winston continues to flirts with possible arrest by the ââ¬Å"Thought Policeâ⬠for a thought crime, which is any written or though of rebellion against the Party. Juliaââ¬â¢s rebellious behavior is more to gratify herself, rather then the destruction of the party. Julia defies the party in search of personal pleasure. She is content with her life in Oceana because she does not consider a better life not under the oppression of the Party. Julia is interested in the present time with Winston, rather than in exposing the Inner Party secrets. Julia is more rational then Winston because she sets up secret gatherings in places where she knows they will be safe. At Winstonââ¬â¢sà and Juliaââ¬â¢s first private meeting, Juliaââ¬â¢s true colors begin to shine. Cautiously, Winston asks, ââ¬Å"Have you done this before?â⬠and Julia replies, ââ¬Å"Of course. Hundreds of times-well, scores of times, anyway replied Julia.â⬠Here Julia enlightens Winston about the corruption within the Party, which is music to his ears. Winston is pleased to hear that corruption exists within the Inner Party because the Party is supposed to have very strict rules and regulation that do not allow corruption within. Winston knows that any anarchy that exists within the Party is a sign that corruption can take over and lead to the Partyââ¬â¢s defeat. Winston believes the Proles are the only group who can organize and revolt against the party. Winston considers the Proles, who are outside of the Outer Party and who live in the worst conditions as the main laborers in Oceania, as ââ¬Å"â⬠¦human beings,â⬠while he mentions, ââ¬Å"we are not human.â⬠At this point Winston has complete disregard for the Party even though any thought against the Partyââ¬â¢s ways means death. Winston reckons that hope for freedom lay only in the hands of the Proles and in turn, the Proles are the only source of revolt for Winston. Even though Winston and Julia start helping each other, they eventually commit crimes that lead to each otherââ¬â¢s betrayal. Their subversive behavior comes to the attention of the Party and eventually leads to their capture. Winston and Julia arrange secret times to meet in the forest and in the upstairs bedroom of Mr. Charringtonââ¬â¢s shop. They do this even though they are well aware of the fact that the Party would vaporize citizens of Oceania who are considered threats and have their entire existence erased. After the capture of Winston and Julia, Oââ¬â¢Brian tortures Winston physically and psychologically to the point where there is no emotion left inside him, besides the love for Big Brother. ââ¬Å"But it was all right, everything was all right, the struggle was finished. He had won the victory over himself. He loved Big Brother.â⬠There is no will to fight left within Winston. The only things that he held with importance were Julia and the idea that one day, the Brotherhood would thrive. Oââ¬â¢Brian breaks him down and takes away the one person he cherished. When he loses his feelings towards Julia, all of his will is lost and the only love he has is for Big Brother. Oââ¬â¢Brian does not want to simply torture Winston, but to psychologically force him to forget his past ways and accept Big Brother. Even though Oââ¬â¢Brian is able to successfully brainwash Winston and Julia into contradicting their prior beliefs, at first Julia still thinks that the Party ââ¬Å"can make you say anything-anything- but they canââ¬â¢t make you believe it. They canââ¬â¢t get inside you.â⬠Soon, however, she figures out that this is utterly wrong. Julia is ignorant as to how much power the Party holds. She believes that they could force you to say anything, but could never force you to feel or think a certain way. In reality, Oââ¬â¢Brian does indeed have the psycholog ical power to not only make one believe something, but to wish it as well. ââ¬Å"They canââ¬â¢t get inside you,â⬠she had said. But they could get inside you. ââ¬Å"What happens to you here is forever,â⬠Oââ¬â¢Brian had said. Here Julia and Winston realize how wrong they are. Oââ¬â¢Brian uses the only thing in the world that can make Winston betray Julia. Oââ¬â¢Brian breaks Winston down with the torture and at this point he realizes he no longer feels the same way for Julia because he has betrayed her. ââ¬Å"At the time when it happens,â⬠she had said, ââ¬Å"you do mean it.â⬠He had meant it. He had not merely said it, he had wished it. Winston was no longer mentally capable to withstand Oââ¬â¢Brianââ¬â¢s force to change him. By means of torture Oââ¬â¢Brian physically and mentally forces the love of Big Brother upon Winston. Oââ¬â¢Brian accomplishes this goal by the torture in room 101. The room plays a significant role when Winston is locked up in the Ministry of Truth because a fellow prisoner tells him that he would do anything not to return to room 101. The room instills a sense of fear into Winston. Oââ¬â¢Brian cleverly sets Winston up so that the only way out of room 101 is to place someone else in his shoes. Oââ¬â¢Brian wants Wilson to betray Julia, and when faced with his greatest fears he breaks down and says, ââ¬Å"Do it to Julia! Do it to Julia! Not me! Julia! I donââ¬â¢t care what you do to her. Tear her face off, strip her to the bones. Not me! Julia! Not me!â⬠Winston is put against the one thing in the world that he loves. Oââ¬â¢Brian believes that in time of fear one will do anything to get himself out of the situation. He wants Winston to give up Julia because he k nows that she isà the one person that could raise Winstonââ¬â¢s spirits. Once Winston betrays Julia, he can no longer confine in her and therefore ultimately forced to be alone. Winston has no choice but to confine in and seek the love of Big Brother. The subversive force the Party had to control was Juliaââ¬â¢s sexuality and Winstonââ¬â¢s pursuit for the truth. They had to contain it before Winstonââ¬â¢s beliefs spread to the people of Oceana. The Thought police would observe the people and cameras on the streets, so that no one would consider opposing the Party. ââ¬Å"Thought crimesâ⬠and ââ¬Å"face crimesâ⬠were thoughts and facial jesters that showed the Inner Party that rebellion was within. The thought police would arrest residents of Oceana for even the thought of deviance towards the Party. Winston and Julia believed they were stronger then the Party and that they could outsmart it. Their love for each other turned to a love for Big Brother after the psychological breakdown by Oââ¬â¢Brian and the Party. Oââ¬â¢Brian took them to the point where nothing was tolerable, and the only option was to give up the person you love and put them in your shoes, so that you would not have to endure it. At this point, there was no longer a will to stay together and deceive the Party. Once Wilson had been brainwashed and betrayed Julia, he was no longer the same person. ââ¬Å"Under the spreading chestnut tree I sold you and you sold meâ⬠emphasizes just how betrayal became the downfall of Winstonââ¬â¢s and Juliaââ¬â¢s subversive force.

The Bad Effects to Health of Excessive Computer Use
THE BAD EFFECTS TO HEALTH OF EXCESSIVE COMPUTER USE A Research Paper Submitted In Partial Fulfillment of the Requirement In English 102A ââ¬â Writing in Discipline By: Go, Alyssa Y. Vergara, Bellie Anne S. BACHELOR OF SCIENCE IN COMPUTER SCIENCE OCTOBER 8, 2010 CHAPTER 1 THE PROBLEM AND ITS BACKGROUND Introduction Today, computers play a very large part in our daily lives. We use computer for a lot of things like business, education, communication and entertainment. We can find computers almost everywhere nowadays, at offices, at school and even at almost every home. Because of the computerââ¬â¢s speed and efficiency, we always turn to it to get our work done. As a result, many people tend to spend long hours using it. And using the computer for an extended period of time results to several health problems. As computer science students, this means that when we graduate, we will eventually get a job that will require us to use computer for long periods of time. It is important that we should know the risk of our profession such as the health problems that we would most likely have to face. This research could also aid the general public who uses computers in their daily lives. It could help us to know the health problems caused by the extensive use of computers and the possible solutions to prevent or overcome it. Stamatellos(2007) stated in his work that the extensive use of computers can result two possible health problems: the ââ¬Å"Computer Vision Syndromeâ⬠(CVS) and the ââ¬Å"Repetitive Strain Injuryâ⬠(RSI). CVS is a series of eye problems due to staring at the monitor of a computer for a long period of time. RSI is an intense pain felt on a particular muscle, joint or ligament that is used to repeat the exact same movements. If these problems are not treated it could lead to permanent damage to your health and consequently to your life. The health of users are key component in information system. However, people donââ¬â¢t bother to take care of themselves, and when the time comes they discover they have so many illnesses. The widespread use of computers is now casing health concerns. This research discusses the preventions and cures the user can do to keep them healthy at office and at home. There are some ergonomic concepts that we can follow to take precautions to prevent this injuries. Take a break after using computer, do some simple exercise during that time. Stretching and doing some simple wrist in your hands and arms. To prevent injury to typing, place a wrist rest between the key board and at the edge of your desk. To prevent injury using a mouse, place the mouse at least six inches from the edge of the desk. The eye strain is not a serious or long term illnesses. You should get regular eye examination, through this you can take care of yourself. Another one is the back pain, muscle fatigue, it caused by poor posture; get an ergonomic chair it allows you to sit and to use arms and hands in healthier way. Sit properly in the chair, your feet should be flat on the floor. You can just go and take a break and be sure that your workplace is well more designed. Statement of the problem This research focuses on defining the bad effects to health of using the computer for an extended period of time. This research will answer the following questions: * What are the specific health problems we may acquire by using the computer excessively? * What are the causes of the said health problems? * What are the possible solutions we can do to cure or prevent these problems? * What is an ergonomic workplace? * How can we make our workstations ergonomic? Significance of the study This research gives information regarding health problems due to the extensive use of computer among users, computer professionals and its association with working environment conditions. A significant portion of computer users were found to be having health problems and this denotes that the occupational health of the people working in the computer field needs to indicate occupational health problems such as Repetitive Strain Injury (RSI) and Computer Vision Syndrome (CVS). This research further explains that long periods of working at a computer can cause eyestrain and overuse injuries of the hands and wrists. Using this research, employers and managers can help transform working stations to be more ergonomic. The working place will be more suitable and comfortable for the workers. Furthermore, it will lessen the chances of the workers getting computer health related problems. Scope and delimitation This study limits its coverage on the people who are working in the computers for long period of time, particularly company employers identify the health problems that they encounter and to propose possible solution regarding this problem. This study considers every aspect of the employeeââ¬â¢s health information that has an impact on their performance such as their condition regarding office work. The wide of using computers has led some important health concerns, which is associated with occupational safety and health concerns. Many people use computers as part of their job. If you use one and suffer illnesses it may be because of the way you are using the computer. Problems such as suffering from strain in the back of the hand due to excessive ââ¬Ëmouse' clicking, eye strain, shoulder and back pains or stress or neck ache if you use a computer without a break for a long time. The employees suffered this condition because of their heavy work loads and regular night work. Furthermore they face number of health issues particularly (RSI) Repetitive Strain Injuries and (CVS) Computer Vision Syndrome. Methodology The goal of this research is to ascertain the different bad effects of using the computer for an extended period of time. To reach this goal, we conduct surveys and interview of individuals who are working with computers long periods of time. Surveys are done for all the employees of a particular computer company to determine whether there really is an overall increase chance for people who are working with computers to get computer related health problems and to ascertain which health related problems theyââ¬â¢ve got. The data collected from this test are recorded and later tested for relevance. Interviews are done with employees who already have computer related health problem. This is to determine which health problems are more prevalent and which health problems are rare. Using these interviews, we get the possible causes of the said health problems. An inspection of the workplace conducted. This is to test if the working environment is indeed another factor affecting or causing health problems. All of the data collected from the said methods and complied, tested and further analyzed to reach concrete results.
