A Doll s House By Henrik Ibsen - 773 Words

As we are humans we love the repeated events of life. As evidenced in our most loved literature and shows. The great everlasting mask of what is really behind everything or what really is there. Continuously asking why again, again, and again, never satisfied. Nora from A Doll’s House by Henrik Ibsen provides one of the favorite themes linking her to the Showgirls of Las Vegas, the stuffed animals that roamed the land in the past, and Edna from The Awakening by Kate Chopin. Illusion is what seems to binds people but, is the illusion reality or fantasy or both? A Doll’s House covers themes that reoccur in everyday life. Illusion sets the pace in the play as well in our everyday lives. A Doll’s House is a story of Nora, a mother who like a doll or puppet, has been controlled by a master, her father and husband. As the play moves along, it becomes clear that Nora went disobeyed the law and the ideals of her current master her husband to save his life. Once he knows, he is utterly terrified. He never sees it as an act of love until the fear is waivered. That is the last hope of Nora, his second reaction should have been his first, to be a man and support her and their family. Having her final hope diminished, Nora rises to be the one to change her life, leaving her husband and children. This occurrence during it’s time is also somewhat frowned upon in today’s society. Nora in her own way was a showgirl, from the Tarantella, to her own life.

The Evolution of the Computer Virus - 1800 Words

The Evolution of the Computer Virus Introduction In simple terms a virus can be defined as software, which is unwanted and executes arbitrary code on systems. It acts as a small software program, which has the capability of exploiting other software programs in order to piggyback[1]. The terms viruses and malwares are used interchangeably, however, in technical terms, the viruses are a subset of malware and so are trojans, worms and rootkits. The name for the â€Å"Computer Virus† has actually derived from its biological counterpart because of their proximity in properties. Similar to the functioning of biological viruses, a computer virus must use another program to exploit some other program in order to start functioning. Hence, this†¦show more content†¦Ã¢â‚¬ËœThe root of virus evolution can be drawn back to 1949 when the scientist John von Neumann introduced the concept of self-replicating programs. The design suggested by Von Neumann for the self-producing programs is said to be the first computer virus. The predecessors of the current form of viruses date back to the 60s.It was then that a game called â€Å"Core Wars† was developed which had the capability of regenerating every time it was run. This game could also the exhaust the memory of the computer of other players. Similarly, another application named Reeper was developed by the founders of â€Å"Core wars†, which could delete the copies made as a result of running of â€Å"Core Wars†. This turned out to be one of the first antivirus applications. During the same time, another malicious code named â€Å"Brain† was created in 1966, which made the contents of the disks inaccessible by infecting the boot sectors of disks. The main target of this malicious program was MS-DOS which itself was relatively new at that time. The same year, another application named â€Å"PC-Write† was developed which served as the first Trojan. During the development phase of viruses it was soon realized that infecting the files could increase the damages caused to the computer systems. Hence, 1987 saw the appearance of â€Å"Suriv02†, a virus infecting COM files and leading to development of other viruses, like Viernes 13Show MoreRelatedComputer Attacks And Its Impact On The Security1466 Words   |  6 PagesIntroduction With the rising evolution of businesses, the evolution of business and institution data security has also evolved exceptionally.

A Right to Bear Arms Living the Second Amendment Free Essays

Linda Hasselstrom vehemently defends her choice of means to protect herself in her essay, â€Å"A Peaceful Woman Explains Why She Carries a Gun†. The topic of gun control provides for a heated debate between those that believe guns are dangerous and unnecessary and those who rely both on the protection of the gun and the right to its possession. Rather than waxing philosophic on her rights under the Second Amendment, she describes years of feeling powerless and finding that the conventional and more passive methods of self-defense are simply ineffective. We will write a custom essay sample on A Right to Bear Arms: Living the Second Amendment or any similar topic only for you Order Now Hasselstrom makes a convincing case for her choice to carry a gun. The most persuasive aspect of the essay is the way that Hasselstrom leads the reader to the obvious conclusion that gun possession was her only option. She describes, on page 371, the advice given to women to avoid certain situations. While she complies, she is irritated at the idea that the precautions only apply to females, and that females must fear men. Next, she describes incidents in which she felt helpless because more physically powerful men were immune to polite requests and common decency. Instead of going directly to the gun, she spent time learning martial arts and self-defense, only to realize that the sheer size difference was too great a disadvantage. Her most convincing argument is the story of the woman who called for help for a flat tire only to be raped and beaten. Hasselstrom’s implication is that if the woman had a gun in her possession, it never would have happened. In conclusion, Hasselstrom does not suggest that every woman carry a gun, nor does she recommend using that gun to threaten anyone unnecessarily. Rather, she keeps the gun for protection and only reveals it in order to protect herself. Not only is â€Å"A Peaceful Woman†¦Ã¢â‚¬  a convincing argument for gun possession, but it is also a tribute to the lasting nature of the Second Amendment.

The Stories Barn Burning Written By William Faulkner And Pauls Case W

The stories "Barn Burning" written by William Faulkner and "Paul's Case" written by Willa Cather both have two separate characters with very similar troubles. Each has a uniquely sad narrative. "Barn Burning" is a sad story because it not only shows the classical struggle between the underprivileged and the privileged classes, but also the struggle between a father and his son, Sarty. Together, these two boys share comparable lifestyles. Each has conflicts with his father, fantasize of a wealthier existence, and flee from the tribulations in his life. Sarty's main dilemma is his loyalty to his family, which collides with his disappointment and suppressed dislike for his own father. He tends to hide his feelings by denying the facts, "our enemy he thought in that despair: ourn! mine and his both! He's my father!" (Faulkner 171). Sarty appears to be fearful of his father: "If I would have said they wanted only truth, justice, he would have hit me again. But now he said nothing. He was not crying. He jut stood there." (Faulkner 173) In comparison, Paul and his father also have conflicts and Paul too seems to be afraid of his own father. He decides that he would much rather spend the night in the cellar of his house than go inside and face his father. Paul does not feel as much at home when he is at his father's house as he does at Carnegie Hall where he works as an usher and spends most of his time. Paul's teachers and his father believe his working at the theater affects his schooling. As a result, Paul's father takes him out of school and forces him to work for a company referred to only as the firm of Denny and Carson as an office boy. Paul's dream to live like the stars is taken away when his father forbids him to work, visit, or go anywhere near the theater. It is at Carnegie Hall that Paul became struck by the glitter and the starlight of the stage. He is not star struck in the sense that he wanted to perform in any way; he is simply content to observe others' performances. He is struck in the sense that he wants to live the way the characters in the plays do. He imagines them living to all the extent of their money, glutting on beautiful music, art, and life. Sarty, like Paul, is somewhat materialistic. He dreams of a large house and the comfort of money. He desires to be in a higher-class distinction despite his father's bitterness regarding the upper class. Sarty views the de Spain mansion as a citadel protected against momentary stings from his father, "the buzzing wasp." (Faulkner 174) His father sees the house as "pretty and white," built on "sweat, nigger sweat. Maybe it ain't white enough yet to suit him. Maybe he (de Spain) wants to mix some white sweat with it." (Faulkner 175) Paul pocketed nearly one thousand dollars from the cash in the deposit belonging to the company his father made him work for. His dream is shorted by his crime when the story of his theft and his father's search is published in quite a few large newspapers. Instead of facing his crimes and his father, he jumps in front of a train, thereby, of course, committing suicide. Paul's last thoughts are on the things that he will never get to do, because he ended it all before his time. Like Paul, Sarty runs away from the only life he has ever known and all of his family. Sarty wants to live out his dream, which consists of a moral life according to his own values.

Fashion Trend Forecasting Research Paper Example

Fashion Trend Forecasting Research Paper Example Fashion Trend Forecasting Paper Fashion Trend Forecasting Paper The environmental protection is one of the main concerns world-wide and the textile and fashion industries also started to respond for the cause of earth through eco-friendly clothing. Eco friendly textiles include fabrics which are non-toxic, carbon-reducing, recyclable, energy saving and biodegradable. The consumers are also more concerned about the environment and there is an increase in consumption of green products but at the same time fashion and style plays a vital role in setting the trend. Eco-friendly fashion is all about making clothes that take environment into account and at the same time producing fashion goods for consumers. The reason for forecasting the eco friendly clothing trend is that there is a rising demand in eco-safe textiles and garments. Though there is continuous development in almost all the products our focus is more on the kids wear, eco green T-Shirts and denim wears. Many big brands like Levis, Kuyichi and Nudie had already started their campaign on producing eco friendly denims and there is a continuous development in doing the same more fashionable and stylish (www.wgsn-edu.com). Fashion Trend: The eco friendly clothing is still in the developing stage which is a Fringe in terms of fashion trend forecasting. As eco fashion is gaining more and more awareness among the society and people. My focus will be on Denim and Kids wear trends. : In general Organic cotton is used for most of the eco friendly clothing production. Based on Manmeet (2009) article about Organic clothing, there is an increase in demand for organic cotton market, which was about 3.5 billion USD in 2008, and estimated to increase to 4.5 billion USD by this year 2009 and reach 6.8 billion USD in 2010. These figures shows us the increasing importance in the use of organic cotton in the field of eco friendly clothing production. Denim: The eco-denim products are the point of focus for many denim brands and their designers and consumers who are looking for sustainable clothing and also with the blend of style and fashion (Helen, WGSN, 2008). As there are many brands going through the process it looks like a positive growth and this trend is not looking like a short term passing trend. President and designer at Earnest Sewn, Scott Morrison said: It is my sincere hope that eco-conscience fashion is much more than a trend, but that remains to be seen for a long time (www.wsgn-edu.com). The main reason behind this is that people understand the importance of organic, environment friendly products and their place in consumer market. For autumn/winter 2008/09 most denim wears goes back to 70s styles. Levis Red Tab look at 70s urban tribes also Wrangler returns to 1970s bootcuts, high waists and flares are black. The flare becomes main collection for the men and women. The main factors here is that, the Denims in this range of collection are 100% organic certified eco-jeans dyed using natural indigo dyes (Amy, WSGN, 2008). In Denim Dyeing process there are many eco-friendly dyed product tried in winter 2008 by Levi Strauss Europe. They have tried small range of organic cotton T-shirts with plant derived tones. Natural indigo blues obtained from several plant sources were used by European brands. This increased the demand of Blue Blood, Evisu, Kuyichi and Howies denim pants (H ROs, WGSN, 2008). There is clear evidence of the growing importance of natural dyes in the context of contemporary environmental concerns, which include biodiversity and renewable resources. Based on the swatch report by WGSN Denim team (2008) the main trend is forecasted for coming spring/summer 2009. This is based on European trade shows and it clearly says there is a strong focus on coloured weft with natural indigo shades in denims and in the case of styles the 70s style is going to influence the denim shades continuing from the last session. The new look for this session for denim is blends like cotton linen blends which give slubby rustic look and it is also experimented with alternative natural fibres. Then, the lighter weight denims trend up and there is a return of bonded denim jackets. Kids Wear: Environmentalism is the high priority and biggest concern for the parents of coming generation kids. As there is continuous change in environmental factors and hazards followed by the same, parents nowadays takes extra care over their kids in everything they do and what they wear and play with. The kids wear companies are taking extra care and effort to give the parents what they expect. Apart from apparels simply made from organic cotton, the companies use many a more substitute products and use alternative materials for supporting environment. Danish brand Katvig has introduced sustainable bamboo and soya into the kids range: for autumn/winter 2007/08, its a knitwear blend of soya/cashmere and for summer 2008, its organic socks and printed essentials which are made of super soft bamboo/cotton/lycra mix. It is pretty clear that, bamboo is an important trend setter during the year 2008 being a newly introduced product in these kids wears range (Tess, WSGN, 2007). During Spring/Summer 2008, Bubsquash was introduced. Bubsquash exhibited its range of organic baby wear at premier kids as a brand new thing which contains vegetable and fruit photo prints with humorous statements appearing on it. In this session there are some new additions in childrens loungewear, to include sophisticated, beautiful, and functional pieces that can be worn with ease and comfort. This will include hand-printed T-shirts, wide-leg drawstring pants, tunics and pullovers (H Tess, WSGN, 2007). Latest trends: BBCs Thread features some of this seasons hottest looks from colourful skinny jeans to eco cargo shorts, boho chic to urban and tribal prints to stripes. Proving that you dont have to be non-environmentally friendly to be chic and glamorous, the online magazine claims to bring its readers the latest in eco-fabulous style. For fashion-conscious females, wearing environmentally-friendly fashion no longer means looking hippy and it is possible to look stylish (www.bbc.co.uk). Future demands: Buyers are becoming increasingly aware of negative effects of pollution and textile related allergies. An extreme rise in acceptance of ecological products in textiles is registered at the buyers end. Mounting demand of eco-friendly products has led manufacturers to adopt eco-friendly products and this led to increase in importance of eco-labels. Oeko Tex standard 100 is one of the main institution bodies which test the textile harmful substance standards all over the world. It approves and gives eco-labels. Eco-labels which depicts the eco-friendliness of the textiles and garments are widely amicable by the buyers, certifying that this products dont include chemicals, which may be harmful to the wearer (Gautham, 2006). There are many researches undertaken and observations were made on trade fairs by Oeko Tex standards to know in detail, the awareness for the consumers about the sustainability and product quality while purchasing and the demand for those products in the global market. In the Heimtextil trade fair (2009), there is an instinct view on increase in sustainability and quality demands. The research on retail market and the important issues when buying clothing and textiles (Jorg, 2008) shows us, product quality and skin-friendliness for the wearer are closely placed with fashion and social consideration. Based on this we could say that, In future the buyer will consider eco friendly materials as well as fashion and style. So there would be increasing demand for these garments in future. Conclusion: The emerging trends in eco friendly clothing and garments are analysed and it is found there is an increase in environmental awareness and the buying behaviour according to the global change. The trend showed us that eco fashion is not only about hippie skirts and shorts but also with more number of fashion and styles. The denim wears and kids wear trends are taken into consideration for my research on trend. Based on, Media scan on trade and fashion shows and observing the experts research in eco friendly clothing I came up with short term trend changes in denim jeans, as we know through trend forecasters website WGSN, the 70s trends are returning to denim fashion but with the organic cotton as a material and dyed using natural indigo dyes. This trend continuous for the Spring/Summer 2009 and new look is coming in form of denim blends in this session. In case of kids wear, the usage of new fibres soya and bamboo is the recent emerging trend and at the same time it gives stylish look . Finally, this eco friendly garment is considered as more than a trend as there is continuous environmental awareness building in the consumers mind; this eco fashion would stay longer as a classic.

Learn About Sunspots, the Suns Cool, Dark Regions

Learn About Sunspots, the Sun's Cool, Dark Regions When you look at the Sun  you see a bright object in the sky. Because its not safe to look directly at the Sun without good eye protection, its difficult to study our star.  However, astronomers use special telescopes and spacecraft to learn more about the Sun and its continual activity. We know today that the Sun is a multi-layered object with a nuclear fusion furnace at its core. Its surface,  called the photosphere, appears smooth and perfect to most observers. However, a closer look at the surface reveals an active place unlike anything we experience on Earth. One of the key, defining features of the surface is the occasional presence of sunspots. What are Sunspots? Beneath the Suns photosphere lies a complex mess of plasma currents, magnetic fields and thermal channels. Over time, the rotation of the Sun causes the magnetic fields to become twisted, which interrupts the flow of thermal energy to and from the surface.  The twisted magnetic field can sometimes pierce through the surface, creating an arc of plasma, called a prominence, or a solar flare. Any place on the Sun where the magnetic fields emerge has less heat flowing to the surface. That creates a  relatively cool spot (roughly 4,500 kelvin instead of the hotter 6,000 kelvin) on the photosphere.  This cool spot appears dark compared to the surrounding inferno that is the Suns surface. Such black dots of cooler regions are what we call sunspots. How Often Do Sunspots Occur? The appearance of sunspots is entirely due to the war between the twisting magnetic fields and plasma currents beneath the photosphere. So,  the regularity of sunspots depends on how twisted the magnetic field has become (which is also tied to how quickly or slowly the plasma currents are moving). While the exact specifics are still being investigated, it seems that these subsurface interactions have a historical trend.The Sun appears to go through a solar cycle about every 11 years or so. (Its actually more like 22 years, as each 11-year cycle causes the magnetic poles of the Sun to flip, so it takes two cycles to get things back to the way they  were.) As part of this cycle,  the field becomes more twisted, leading to more sunspots. Eventually these twisted magnetic fields get so tied up and generate so much heat that the field eventually snaps, like a twisted rubber band. That unleashes a huge amount of energy in a solar flare. Sometimes, theres an outburst of plasma from the Sun, which is called a coronal mass ejection. These dont happen all the time on the Sun, although they are frequent. They increase in frequency every 11 years, and the peak activity is called solar maximum. Nanoflares and Sunspots Recently solar physicists (the scientists who study the Sun), found that there are many very tiny flares erupting as part of solar activity. They dubbed these nanoflares, and they happen all the time. Their heat is what is essentially responsible for the very high temperatures in the solar corona (the outer atmosphere of the Sun).   Once the magnetic field is unraveled, the activity drops again, leading to solar minimum. There have also been periods in history where solar activity has dropped for an extended period of time, effectively staying to solar minimum for years or decades at a time. A 70-year span from 1645 to 1715, known as the Maunder minimum, is one such example. It is thought to be correlated with a drop in average temperature experienced across Europe. This has come to be known as the little ice age. Solar observers have noticed another slowdown of activity during the most recent solar cycle, which raises questions about these variations in the Suns long-term behavior.   Sunspots and Space Weather Solar activity such as flares and coronal mass ejections send huge clouds of ionized plasma (superheated gases) out to space. When these magnetized clouds reach the magnetic field of a planet, they slam into that worlds upper atmosphere and cause disturbances. This is called space weather. On Earth, we see the effects of space weather in the auroral borealis and aurora australis (northern and southern lights). This activity has other effects: on our weather, our power grids, communication grids,and other technology we rely on in our daily lives. Space weather and sunspots are all part of living near a star.   Edited by Carolyn Collins Petersen

Current events report and analysis Essay Example | Topics and Well Written Essays - 500 words

Current events report and analysis - Essay Example As result of the increase in the supply of the oil, the price of the oil has gone down in the country. The demand for oil in the other oil consuming major countries like Spain and Italy had been due to the crisis that these countries have been experiencing. Thus among the other developed countries the both the consumption and the production of oil in the United States has been the highest (Norris 1). In respect to the above article, the demand and supply model has been fit and the analysis has been done from the perspective of the oil prices of the United States. The diagram below depicts the demand and supply of oil in the economy of US. The downward sloping curve is the demand curve and the upward rising curves are the supply curves. In the figure it can be seen that the initial supply curve of oil in the economy of US is given by S2 which was the supply of oil in the previous period. The demand and supply curve in the initial phase intersected at the equilibrium price of P2 and quantity Q2. In the present period the supply of oil in the economy increases and the new supply curve shifts to S1. Therefore at the same level of demand for oil in the economy the demand and supply curves intersect to form a new equilibrium the new equilibrium point is formed at the price P1 and at the quantity Q1. If the macroeconomic policy of aggregate demand and supply is applied to the article above it can be found that the rise in the consumption has resulted in a push in the demand for oil. This in turn has increased the level of supply of oil in the economy. In the above figure the aggregate supply and demand curve has been drawn. The initial aggregate supply curve is AS. Due to the rise in the production of oil the new aggregate supply curve would be at AS1. The rise in the production of the oil has led to the fall in the prices. As a result the price level of the economy decreases. The spending of the people increases the aggregate demand in the economy. This results in
