Simon Character in Lord of the Flies Essay Example for Free
Simon Character in Lord of the Flies Essay In this extract all of the boys take part in the murder of Simon. Simon is described as ‘the beast’ during his killing. Lord of the Flies is an allegorical novel, the death of Simon also symbolises the death of spirituality. After his brutal death Golding describes ‘his check silvered and the turn of his shoulder became sculptured marble’ this almost romantic description is an emblem of Simon’s purity. The setting is a frightening one. It is night time, but not completely dark as there are ‘flashes of lightning’ this gives a hint to the reader that this chapter will not have a happy ending. Golding uses pathetic fallacy throughout the extract to build suspense and add to the atmosphere, ‘sulphurous explosion’ this is a contrasting quote compared to the beginning peaceful setting of the novel, ‘the brilliant fish flicked away’ this is evidence of the shift within the novel from good to evil. The sounds Golding describes are the sounds of fear. The extract starts with just a few drops of rain but even when these drop they make ‘Individual sounds’ this shows that even a small thing can have a big effect. Golding starts with just small sounds to help build the tension. The rain also reminds the reader rightly of world war two as Ralph says ‘you’ll have rain like when we dropped here’ which links to the atom bomb and the irony that Piggy keeps on saying ‘what would the grown-ups think?’ when they themselves are in a war. Twice the thunder is said to ‘blow’ as if it is whipping the boys like a master would whip an animal, as a means of controlling them, Golding uses the weather to alter the mood and to help build the boys up into a frenzy. The use of monosyllabic chanting, ‘kill the beast! Cut his throat! Spill his blood!’ shows a very concentrated power source which drives the boys to do what they would never image on any ordinary day. The use of exclamati on marks means the extract becomes very loud.

Comparing Ruth Prawer Jhabvalas Heat and Dust and Forsters A Passage
Comparing Ruth Prawer Jhabvala's Heat and Dust and Forster's A Passage to India Literature throughout time has contained many similarities. These similarities become even more prevalent when authors share a similar style and inspirations. Two authors that have similar experiences are Ruth Prawer Jhabvala and E.M. Forster. Both these authors have written books that are in the modernism style. Jhabvala and Forster also were fascinated by India and choose the relationships between native Indians and English colonizers as one of their themes. These similarities helped produce books that have similar characters. The women, not native to India, in both Jhabvala' Heat and Dust and Forster's A Passage to India, share many of the same attributes.      The most obvious similarities are those shared by Jhabvala's character Olivia and Forster's character Adela. Throughout the books, these two characters share many characteristics and experiences. The first experience they shared while in India is that both women are social with the native Indians. This was unacceptable to all Anglo-Indians. Olivia frequently visited the Nawab at his palace. She also entertained him and his companion, Harry at her home. For the majority of the book, Olivia's husband, Douglas is unaware of how frequently she visited the Nawab. If Douglas had been fully aware of Olivia's actions, he would have been enraged. Proper Englishwomen were not to associate with natives while unchaperoned. Adela, Forster's character, had a similar experience. She desired to see the 'real'; India. To allow her to do this, a native offered to take her to the Marabar Caves, a local landmark. Again, Englishwomen were not to associate with the natives. Her potenti al fiancà © and host, allowed her to go under the condition that his mother and an Englishman were also included in the group. Socializing with Indians is only one common experience Olivia and Adela had.      Another similar experience occurs near the end of both books. Both Olivia and Adela had relationships irreparably changed through the influence of India. If neither women was in India, their relationships probably would have remained intact. Olivia's marriage to Douglas was ruined because of her relationship with the Nawab. Olivia became very close with the Nawab. She eventually came to carry his child. Because Olivia did not believe the child ... ... this advice happened at the Bridge Party. Again, they told Adela that she was superior to the natives and should act accordingly. Despite all their attempts Adela did not adopt their opinions about the natives. She attempted to form her own. The Anglo-Indian women in both novels attempted to supply advice to the younger women.      Despite being written by different authors, the female characters in Jhabvala's Heat and Dust and Forster's A Passage to India are very similar. In spite of the similarities among characters the novels themselves are different. Not only do the novels have different themes, they were also written through different points of view. While A Passage to India is mainly written through the view of a narrator, the point of view in Heat and Dust changes from the narrator to a third person view developed through Olivia's letters. These are a few of the many differences between the novels that occur regardless of the fact that the novels have similar characters. Works Cited Forster, E.M. (1992). A Passage to India.

Aphasia: A Language Disorder :: Biology Essays Research Papers
Aphasia: A Language Disorder "My most valuable tool is words, the words I can now use only with difficulty. My voice is debilitated - mute, a prisoner of a communication system damaged by a stroke that has robbed me of language," stated A. H. Raskins, one of approximately one million people in the United States who suffer from aphasia (1), a disorder which limits the comprehension and expression of language. It is an acquired impairment due to brain injury in the left cerebral hemisphere. The most common cause of aphasia is a stroke, but other causes are brain tumors, head injury, or other neuralgic illnesses. Of the estimated 400,000 strokes which occur a year, approximately 80,000 of those patients develop some form of aphasia (2). Another important observation is that within the United States, there are twice as many people with aphasia as there are individuals with Parkinson's disease (2). Yet, what is so astounding is the lack of public awareness about aphasia. Aphasia attacks an intricate part of a person' s daily life - the simple act of communication and sharing. The disbursement of such a tool deprives an individual of education learned through their life, often leaving the ill fated feeling hopeless and alone. In considering the effects of aphasia, a deeper analysis of the two most common forms of aphasia will be examined: Broca's aphasia and Wernicke's aphasia. While both forms occur usually as a result of a stroke in the left hemisphere of the brain, their particular site of impairment produces different side effects in an individual's comprehension and speech. These regions have been further studied through experimental researches such as positron emission tomography (PET). Moreover, although there is currently no cure for the disorder, there are treatments and certain guidelines to follow when encountering an aphasic. In physiological terms, Broca's aphasia and Wernicke's aphasia occur in the left hemisphere of the brain, which is responsible for controlling the right side of the body along with speech and language abilities. Broca's aphasia affects the frontal lobe adjacent to the primary motor cortex, and Wernicke's aphasia affects the posterior portion of the first frontal lobe (3). A general distinction made between the two disorders are that Broca's aphasia limits speech, while Wernicke's aphasia limits comprehension. Broca's aphasia characterizes patients as people who has loss the production of complete sentence structures in speech and writing. Although the individual may retain the usage of nouns and verbs, the aphasic may have lost all forms of pronouns, articles, and conjunctions (3).

I Feel Great
DBQ 15: The Debate Over American Imperialism Catriona Whalley Imperialism was not a proper and legitimate policy for the United States to follow at the turn of the 19th century. Americans defended their country’s attentions with ethnocentric, hypocritical, and overall un-American rationalizations. They imperialized for their own profit and benefit, and had no true justification behind their reasoning. While Americans did not usually claim that they anted to maintain rule of other territories for American Profit, it was a factor.Some saw the Pacific Ocean as the key to thriving trade in the future; by holding claim to that ocean though ruling the Philippines they would hold â€Å"the power that rules the world. †(Doc 5) The country was also needed to meet the US’ growing production demands (Doc 2) For the States to turn the land they acquired over to France or Germany – who were commercial rivals to the US- would harm their own trade. (Doc 3) If you were t o strictly interpret the Declaration of Independence, you would find that the U.S’ reasons for imperializing go against the beliefs set by their founding fathers. The declaration clearly states that you cannot govern any country but your own against their will, even if it is believed that it is for their own good. (Doc 4) The loved President Abraham Lincoln once said, â€Å"no man is good enough to govern another man without that other’s consent,†as advocates of self-government, they should have listened to these words of wisdom.Americans also claimed that as a superior, more civilized nation, they held the duty to â€Å"led in the regeneration of the world†, to spread their beliefs, customs and religion. (Doc 1) The declaration cites that â€Å"All men are created equally,†therefore all men outside of the U. S should be treated as equals to Americans. (O. I) In the past the United States made foreign countries sign a document called the Monroe D octrine; this contract banned any country from imperializing the States.The United States was also born in a revolt against colonialism. Both of these events in the past cause the country to be considered a hypocrite; how can they claim that no country can imperialize and rule them, but they can do the same to others? (O. I) The United States only began to imperialize as its thirst for more power grew after completing manifest destiny. As a country that boasted democracy, will of the people, and self-government, they should not have imperialized during the turn of the 19th century.

Coastal erosion essays
Coastal erosion essays For many decades the approach to rapid coastal erosion was to build up sea defences, to try and slow down or even stop the erosion. Initially the attempts were thought a success, however after some years it was realised that the power of the sea and waves could overcome human attempts. Only could protection be a success if huge costs were going to be involved. Many methods around the British Isles have taken place in he last 50 years with many failures occurring. It is very rare to find a coastline that shows a decrease in the rate of erosion over many years after defences are in place. In fact in places the defences seem to have speeded up the erosion process. Coastal erosion is a natural process of erosion, transportation and deposition, interfering with this balance could be to blame for the rise in erosion on the coasts of some areas. Groynes have been built out to sea in many areas of the British coastline. Their aim is to trap material and thus slow down the rate of longshore drift. However, these groynes in some areas are been blamed for the rise in erosion rates further down the coast. On the Holderness coastline in Humberside, erosion is taking place at a rate of about 2 metres per year. Along this coast there is a strong action of longshore drift taking place, which over centuries has produced a spit to form on the southern tip of Holderness, called Spurn Head spit. The spit is over 4km long and 100 metres wide. The majority of this coastline is glacial till, a soft fragile material, which is easily eroded. This however is not thought of as the only reason for the rapid rates of erosion. Human interference is thought to be another cause, as a result of the sea defences put in place. A rock groyne was built at Mappleton, to create a wider beach. This in turn would help protect the coastline, by absorbing the wave energy. Then at Withernsea a concrete sea wall with a splashback and boulder rip-rap in front of it was creat...

French Adverbs ~ Les Adverbes
French Adverbs ~ Les Adverbes An adverb, one of the eight parts of speech, is an invariable word that modifies a verb, an adjective, or another adverb. Adverbs provide information about the words they modify, such as when, where, how, how often, or to what degree something is done. See the list of some common French adverbs at the end of this lesson. Word Order with Adverbs In English, adverb placement can be arbitrary: some adverbs may be found in front of or after the verb, or even at the beginning or end of the sentence. This is not often the case in French, which has much stricter rules about placement. The following rules apply to the majority of situations, but there are exceptions. For detailed information, see my lesson on the placement of French adverbs.1. When a French adverb modifies a verb, it is placed after the conjugated verb. Nous avons bien mang. We ate well. Je regarde souvent la tl le soir. I often watch TV in the evening. Often, I watch TV in the evening. I watch TV in the evening often.   2. When an adverb modifies an adjective or another adverb, it is placed in front of the word it is modifying. Je suis profondment mu. I am deeply moved. Nous avons trs bien mang. We ate very well. Common French Adverbs Nearly every French word that ends in -ment is an adverb, and its English equivalent almost always ends in -ly: gà ©nà ©ralement - generally. For more information, please see adverbs of manner. Here are some of the most common French adverbs: French English Type of adverb actuellement currently adverb of time assez quite, fairly adverb of quantity aujourdhui today adverb of time aussi as comparative adverb beaucoup a lot adverb of quantity bien well adverb of manner bientt soon adverb of time dj already adverb of time demain tomorrow adverb of time enfin finally adverb of time ensuite next, then adverb of time heureusement fortunately adverb of manner hier yesterday adverb of time ici here adverb of place l there adverb of place l-bas over there adverb of place longtemps for a long time adverb of time maintenant now adverb of time mal poorly adverb of manner moins less comparative adverb parfois sometimes adverb of frequency partout everywhere adverb of place peu few, little adverb of quantity plus more, ___-er comparative adverb quelque part somewhere adverb of place rarement rarely adverb of frequency souvent often adverb of frequency tard late adverb of time tt early adverb of time toujours always adverb of frequency trs very adverb of quantity trop too much adverb of quantity vite quickly adverb of manner

Political Theory Essay Example | Topics and Well Written Essays - 1250 words - 1
Political Theory - Essay Example His Second Treatise on Government, in particular is a comprehensive collection of essays on various aspects of social organization. But theories do not always translate into practice and so governments always do not fulfill the purpose for which they were conceived and formed. We should also remember that electoral processes and democratic institutions that constitute modern governments are also beset by serious flaws. In the present global political scenario, as was the case during the period of European Imperialism, governments concerned themselves with matters way beyond the maintenance of civil liberties to its population. That is, governments have never been strictly political formations, but have always served vested commercial and class interests. A history of European Imperialism is full of such examples, where exploitation of commercial opportunities led to expansion of territories and colonies. It should also be noted that while governments are needed to maintain peace and order in civil societies, there have been plenty of instances in which they have abused their power in suppressing dissident voices and threats to power. Writing his Treatises on Government toward the end of seventeenth century, John Locke could not have foreseen the scale and scope of abuse of power that governments have since exhibited. While this is not mean that Locke’s Treatises are impractical, they do point to the gap between what is real and what is ideal. Also, Locke’s Treatises focus on the interactions between government and the individual as well as the interaction between fellow citizens. There is a lacuna in Locke’s Second Treatise about the nature and dynamics of power relations between governments and how this could undermine the civil liberties domestically. The nature and complexion on demographics has altered considerably in the period since Locke’s analyses. In an

Math Finance Problem Example | Topics and Well Written Essays - 250 words
Finance - Math Problem Example This normally involves hedging a position in one asset by taking a balancing position in different asset that highly correlates with the first asset (Mishken et al. 2009). Complete markets are those markets where every conditional claim is attainable. In this market, there exists a stable price for every asset in all possible positions. As a result, investors can buy insurance contracts to protect against uncertainty in future states and time (Mishken et al. 2009). Arbitrage involves taking concurrent positions in diverse assets such that a riskless profit which is more than the yield on the riskless asset is guaranteed. First arbitrage occurs when an investor makes an investment with no existing net assurance that there would be a positive profit. Second arbitrage occurs when an investor has the opportunity to make an investment with a negative net commitment at that time. Prices are said to be fair if and only if there exists no
Population policy Article Example | Topics and Well Written Essays - 500 words
Population policy - Article Example Further, the article shows (Table 2) the effects of the policy change. With the prior 1979 priority on increasing birth defects, the resulting 2011 population census shows 71 percent of the 2011 Iraq population belongs to 15 years to 64 years age group. In the 2006 census, 70 percent of the population similarly belonging to the same 15 years to 64 years age group. When the 1980s change to the birth control population program was implemented, the birth rate consequently decreased. The population reduction effects can be seen in the 2011 and 2006 population. The resulting 2011 population census shows a smaller 23percent of the 2011 Iraq population belongs to 0 years to 14 years age group. In the 2006 census, a similarly smaller 25 percent of the population similarly belonging to the same 0 years to 14 years age group. Further, societal factors triggered the Iranian population policy change. In 1986, Iran unfavorably became overpopulated, 74 million people. More women shifted from child bearing to work and school priorities. The shift triggered the lower birth rates (Groth, 2012). With lesser population, food supply increases. There are lesser hungry individuals. Prices of food decline. Government can allocate lesser amounts to feeding a smaller population. Hunger being resolved, the people are better contributors to the society’s betterment. More well-fed people produce more quality outputs. Food supply affects Iraq’s population growth. Famine crops up when the food supplies are not enough to feed the population. With famine, some people die of hunger. Lack of food discourages many reasonable families from procreating. Consequently, the scarce food supply normally triggers a reduction in Iraq’s population growth rate (Murray, 2013). I can improve the current policy. I require a portion of the Iraq government’s funds detoured to the production of more agricultural food products. Government hires more

Should Britain adopt the Euro Essay Example | Topics and Well Written Essays - 1000 words
Should Britain adopt the Euro - Essay Example This transformation has been successful in meeting its goal. Greece has since adopted the Euro while Sweden, Denmark and Britain, the latter of which is not considered a European country, have not. Many legislators and economists have suggested that it is simply a matter of when, not if, the UK will adopt the Euro. This discussion examines the benefits the UK will retain when this eventually happens and answers the legitimate concerns of those opposed to the transformation. Certain indisputable results have occurred following the conversion to the Euro. It has eliminated the costs and risks involved when exchanging foreign currency with other counties of the EU and made more transparent the cost of products. By adopting the Euro, Britain would be allowed a place on the European Central Bank (ECB) board thus being able to participate in the economic policy of the EU. This would enhance the political influence of the UK which in turn would produce beneficial long-term opportunities for its economy. According to many published studies conducted regarding the effect of the Euro, using a common currency has already proven to augment trade and competitiveness within the countries that use it. One study that measured the influence of the Euro on trade discovered â€Å"countries that share a common currency trade about three times as much as countries without a common currency†(Micco et al, 2003). It is clear that trade between Britain and EU countries would escalate if the same currency was used. Differences in types of money present barriers to trade because of the cost factors involved in converting it. Large corporations would save significant amounts and open up previously unfeasible opportunities of trade to smaller companies. Reducing the cost of trade will make Britain more competitive as companies will be able to charge less for products yet yield
Comparison of two Non-sense Children Texts Essay
Comparison of two Non-sense Children Texts - Essay Example Comparison of two Non-sense Children Texts Mind is the space where all the garbage of the logical thinking is stored. Suppressed emotions, feelings, expressions, thoughts, opinions and desires are all stored in your mind. It is chattering most of the times without you having any control over it (osho p.51). To enter the deepest core of the soul, one has to take a route which the mind is not trained to understand. And that is what the nonsense poems and the nonsense works do; they show us the sensible things in life through nonsense language. And hence, goes deep into our heart. Lewis Carroll’s â€Å" Alice in wonderland†and Edward Lear’s â€Å"A book of Nonsense†are the product of a very an intelligent mind. They have used all the elements of the imaginations, which might seem nonsense to the adult mind, to create poems and stories that make immense sense. Lewis Carroll has created a girl called ‘Alice’ who, one day, slips onto the world of wonder while chasing a rabbit (Lewis, Carroll, 1865 p13). Edward Lear’s â€Å" Book of nonsense†consists of small poems full of different people experiencing weird things. These two works have used nonsense language to drive ideas and thoughts that have a very deep meanings of life. The nonsense work always play with ideas that seem logical by using the words in topsy-turvy way and the nonsense often comes with a message of strong meaning with it rather than a lack of it ( Lear p.vii)

Nicodemus and samaritan woman Essay Example for Free
Nicodemus and samaritan woman Essay Nicodemus and samaritan woman BY wtxY16 Summarize, explain and compare the meeting of Jesus with Nicodemus in John chapter 3 with his meeting with the woman at the well in John chapter 4. Introduction In the fourth gospel John we are told about when Jesus has two encounters with two completely different people and he talks to them about God and himself. He teaches them about spiritual water and how he is the messiah. Im going to talk about these two meetings and compare them with one another to see the differences and the imilarities between the two. Jesus and Nicodemus, The meeting with Jesus and Nicodemus is a very interesting one to say the least because Nicodemus is seen to be a very high up Jewish leader, Nicodemus was a member of a very important Jewish group known as the Sanhedrin which is like a council but for Jews Oewish council). The Sanhedrin was in fact in the end of Jesuss life was actually responsible for Jesuss death, which makes it kind of ironic because Jesus is a Jew. Nicodemus wanted to speak to Jesus in private so they rranged a visit in the dark which instantly shows us that Nicodemus doesnt want to be seen with Jesus because he is a member of the Sanhedrin, its as if he is hiding something or frightened about what people will thin if they see him talking to Jesus. The fact Nicodemus goes to Jesus at night makes him a very interesting person as it makes us question why he sees Jesus at night and not in the day its as if he doesnt have faith in Jesus or believes he is better than everyone else and has a higher knowledge of faith because Nicodemus was a teacher of the Jewish law so is an cademic therefore he can not be seen by others talking to Jesus as he has a higher authority. Jesus said to Nicodemus that he was born again which Nicodemus misunderstood because he is thinking with the mind because he is an academic he isnt thinking with the spirit or the heart, which is what Jesus is implying and trying to get across. The talk ends with Nicodemus leaving in the darkness of the night not understanding who Jesus really is because his academic view cant grasp the hidden meaning that Jesus is portraying. Jesus and the Samaritan woman at the well. Jesus was sat by a well on a hot day this Samaritan woman came to get some water out of the well, which is weird because no one gets water at the hottest point of the day it suggests that she is lonely or an outcast a sinner. Jesus asked the woman for a drink but she wouldnt give him a drink because Jesus was a Jew and she was a Samaritan. They hate each other. Jesus offered another kind of water to the woman this time it was spiritual water and she said give me that water so I wont go thirsty. Jesus reveals what the woman nas done wrong she has had five husbands and for this the other Samaritans do not accept her and she has become isolated because of this. This sows us that she is not a very religious person as she has sinned many times and she know what her sins are which makes her interesting as she becomes a changed woman as Jesus changes her by providing her with spiritual water which makes her realize actually who Jesus really is. Jesus said I am he the messiah. The woman runs off to get other people to see the messiah. The woman is important as it shows us how even though she has committed many sins and has done wrong she is looking for forgiveness and she finds it threw Jesus who shows her the way. Jesuss meeting with Nicodemus and the Samaritan woman are quite different but shows us how the people who know they are good dont always find the answer its the people who lack the faith and believe and dont believe they are good who find the answer. This is shown clearly between the two Nicodemus and the woman because Nicodemus who is part of the Sanhedrin is a very intelligent guy and knows hat he is, doesnt get his life changed by Jesus because he is thinking with the mind not spiritually because he is intelligent, whereas as the woman has committed many sins in her life and is seeking forgiveness and doesnt know she is good. Even though she hasnt done what god asked and has sinned she is the one that understands out of the two who Jesus really is. You wouldnt expect that from a sinner which make it interesting. The Samaritan woman speaks to Jesus in the light at the hottest time of day its as if she knows what she has done and is a wear other people know and herefore she has got nothing to hide whereas Nicodemus talks to Jesus in the Night in the Darkness which suggests there is something we dont know about him, like he is hiding something a truth he doesnt want us to know. Even though he is more religious than the Samaritan woman. The Samaritan womans life is instantly changed but Nicodemuss isnt in fact we dont know if he ever did change. The woman is open in life and is a waiting the messiah to cleanse her whereas Nicodemus is more reserved and thinks he knows it all he comes across as arrogant.

Historical Analysis Of Almayers Folly English Literature Essay
Historical Analysis Of Almayers Folly English Literature Essay The novel Almayers folly is a story of an eastern river that many readers find as an intriguing text. It was Joseph Conrads first novel that opened the door for many more novels to come. Within the novel Almayer, his wife and his daughter all seek out different paths. Almayer wishes to return to Europe, which he perceives as his origin, his wife Mrs. Almayer wishes to return to a pre-colonial Sambir and then his daughter Nina wishes to return to her Malay roots. In the novel we learn about the two dominant cultures of Sambir which are White and Malay but what we dont understand is that by separating the two dominant cultures and returning Sambir to its original state would right an imperialist wrong. There are many controversies against joseph Conrad and his works of writing. It starts off with the question of Is joseph Conrad against or for imperialism? After reading Almayers folly and the other works on reserve I believe it is safe to say that Joseph Conrad was against imperialism. A good author writes what they know, and joseph Conrad used his books and other pieces of work to subliminally talk about his views of imperialism without becoming an outcast is his society. In the introduction of the Historical Guide to Joseph Conrad I read about how authors are shaped by their environment and their historical and cultural surroundings. This point supports how Conrad act as if he is an insider and an imperialist but secretly he feel like an outsider in his society and does not share the same views as everybody else . Almayer`s Folly takes on a special meaning in its characters lives. It is a story about quest and how each character must take on different challenges that make it exciting and interesting. In the novel, Almayer`s Folly, is the quest of the main character Kaspar Almayer but after researching Conrad we see pieces of himself in his main character. The story first takes place on an island called Borneo in the nineteenth century. He is a Dutch colonial who opened up a trading post on the island of Borneo. However, Almayer finds himself wanting to go back to his European routes, he its tired of his unfulfilling island life and rather be back in Amsterdam. Conrad also immigrated from Ukraine to England and was a sailor just how Almayer immigrated from Amsterdam to Borneo and was a sailor. Almayer had two major dilemmas which happened to be from his failed business and his mental suffering due to his failed marriage. In 1878 Conrad attempted suicide; in the story, Almayer was starting to be driven crazy by the long days and the surroundings of the island. He started to feel isolated and depressed and if it was not for his beautiful daughter Nina, Almayer would have taken his life as well. Conrad does not write about suicide because it is not accepted in his social class and since the men who will read his novels are most likely rich and imperialists he must abide by their rules. Almayer wished to have his freedom back just how Conrad wished to have freedom of speech. He absorbs himself in his dream of wealth and power away from this coast where he had dwelt for so many years, forgetting the bitterness of toil and strife in the vision of a great and splendid reward. This quote gives us a look at how Almayer was taken into a dream state wanted to go to a better place. At the beginning of the story, Conrad said Almayer had left his home with a light heart and a lighter pocket, speaking English well and strong in arithmetic; ready to conquer the world, never doubting that he would. This shows how Almayer connects to Conrad in the real world because Conrad did a similar thing but he traveled to England instead of Borneo. Almayer suffered through overwhelming odds in his twenty-five year long struggle. Almayers wife was jealous of how much Nina loved her father. His wife had soon commenced to treat him with a savage contempt expressed by sulky silence, only occasionally varied by a flood of savage invective. Conrad uses the word savage, but he is not referring to a Native American in this text, he is referring the Almayers actions. In the nineteenth century it was not uncommon to call natives savages, because we as humans are scared of what we dont know and dont understand. Conrad, being the anti-imperialist decided to use the word savage without offe nding natives and their culture but while doing so he gives off the impression of still being a part of the social norm. Further in the story we see a character awakening on a very personal level. Nina realizes she is not of pure European blood, she realizes that she will never be accepted as an equal within the Europeans or the whites since she is a half-breed. It is for this reason that Nina chooses to live with the natives. Almayer is an example of someone who is stuck for he stays where he is and he realizes that he is going nowhere which turns out to be his real Folly. Conrad pushes the limits of the social norm when he writes about Nina joining the natives. Being a half-breed in the nineteenth century, you would not be accepted for who you are. Conrad uses this to subtly hint that the way of living is wrong and everyone should be accepted for who they are no matter their breeding background or the colour of their skin. In the summary of Almayer`s Folly we have seen that Conrad has not written in an imperialistic way. It is important to note that Forster, along with Conrad and Lawrence, is one of the few writers of this time period who treats the members of a backward country with the seriousness and sympathy considered necessary for an anthropological understanding by modern standards. This quote from savage and literature explains why we do not see the imperialistic views in Conrad`s novel Almayer`s Folly. Work Cited Conrad, Joseph. Almayers Folly.

The Ghost’s Appeal: Man’s Interest in the Superficial in Toulouse-Lautr
The Ghost’s Appeal: Man’s Interest in the Superficial in Toulouse-Lautrec’s At the Moulin-Rouge Henri de Toulouse-Lautrec’s famous painting, At the Moulin-Rouge, combines striking coloring with abnormal lighting to create a work that addresses men’s superficial interest in women. The dark scene depicted in the painting includes ten people scattered about a restaurant. In the center, two women and three men sit casually around a table while the background portrays two men and a woman peering into mirrors; a second woman (in the foreground) observes the situation. The most arresting aspect of the picture is the dominating, pale face of a woman in the right foreground of the picture. A careful analysis of the painting begins with the study of the portrayal of the brightly-lit women and how the men’s gazes focus that representation and concludes with the viewer’s natural confirmation of that portrayal. This textual look at the picture leads the viewer to the conclusion that it is a woman’s external pomp that attracts a male. Because of Toulouse-Lautrec’s use of lighting, it is clear that the women are central to the painting. Despite the intermixing of men and women, the light falls only on the women, and the men are left in the shadows. Because of this, the eye wanders, not to the men, but to the women; thus, they become the subject of the painting. While this lighting does not appear unnatural, it is far from the customary distribution of light. Hence, the lighting of the women is an intentional attempt to focus the observer on them. Clearly, the objective of At the Moulin-Rouge centers on women. Having established that the females are integral to the work, it is interesting to see how the illumination reveals more about th... ...illed with interesting scenes, people, and ideas, has a distinct theme that emerges by looking at both the women and their male counterparts. From their similarities to actresses to their depiction as ghosts, Toulouse-Lautrec’s women are superficial. It is the men’s obsession with this, however, that reveals the work’s complete theme. Namely, that it is the outward grandeur of a woman that charms men. This point is brought close to home as the viewer realizes that he joins the men in the painting with the same curious interest in the superficial. Toulouse-Lautrec’s masterpiece brings the theme of superficiality’s appeal full-circle by engulfing both the subjects and the audience. NOTES *At the time, "fl†°neur" described the rich, male population that had time to observe and appreciate art. Artists of the day knew that their audience consisted largely of fl†°neurs.

The Film, A Respectable Trade :: Slavery Movies
The Film, A Respectable Trade In the film, A Respectable Trade, the account of slavery is different than usually seen. With an English backdrop, the cruelty of the trade was concealed. The slaves were not laboring in fields, but were being trained in house maintenance. On the streets there are no slaves, they are rerouted to the United States where they are traded. Although the slaves in the film are generally absent from the physical atmosphere, they are vital to the economic growth of Bristol, England. Josiah Cole exemplifies the plight of the struggling businessman. His dream of a better life is echoed in today’s capitalist society. His constant drive is to move out of his father’s small home and into a bigger house in a better section of town. He is a shroud businessman who works hard to be innovative and find a new demand for his product. The economy of Bristol seems to revolve around one product, which is traded and sold. This description of Bristol doesn’t seem very different from many of today’s capitalist societies. The one difference is the product that is being sold and traded. The humans that are being treated as cargo change the whole system from a thriving capitalist society to one of slavery. The town of Bristol becomes the economic center for slave trading. The slaves are seldom seen, but th e money gained from their trading is essential to the town. Cole is taking a business risk by bringing the slaves to Bristol; most of the slaves are traded for other goods by the time they reach the port. He is refining the product he trades in hope that it will fetch him a higher price. The more refined the slave is, the higher price he can charge. This simple business venture is made complicated by social standards because he is trading human beings. Watching this class process of slavery now, from a different societal standpoint, seems foreign. But to the slave traders, such a Josiah Cole, they ignored the fact that they were buying and selling human beings and avowed that they were involved in, A Respectable Trade. A Respectable Trade, portrays slaves in a unique light. Most scenes of slavery in film show slaves working in the fields of southern states in the 19th century.
Example of an Compare and Contrast Essay
My grandmother and I are like dust and dawn, complete opposites. We have different points of views; we come from total different generations; we have different interest. My grandmother was born in Atlanta, GA and married at a young age. She and my grandfather later move up to Jersey City, New Jersey when she was pregnant with my eldest aunt. Life was a lot different in the 1940s than it is now. After sitting down with my grandmother, talking to her about different stuff made me see her in a new light. I spoke with her about how the music was then and now was different. She grew up in a Christian home, so all they listened to was Gospel. I asked her â€Å"what do you think of the Gospel music today?†She answered â€Å"I’m not a big fan of it but I only listen to Mary Mary before I would listen to anything else. They add too much into it and think that because you say God or Jesus it’s a Gospel song. Mary Mary are true Gospel singers.†So, I asked her about the Gospel music that she grew up with, and she had a twinkle in her eye as she explained it to me. She truly loved Gospel from the 1950s to the 1980s. she explained how they had a true meaning and how they had a true message. Technology from then and now is really different. My grandmother declared that their television’s looked like big boxes with a screen on them and cameras were huge. Now, in the 21th century, we have flat screen TV’s and small cameras that can fit in your pockets and can print wirelessly from the printer. Phones were all wired and you couldn’t really move around the house with it; presently, we have wireless cellular phone that you can contact someone from half way around the world without an issue. The environment was a lot safer than it is today; also, that prices were more affordable than they are, that’s why more people are depending on public assistants. My grandmother indicated that you could walk in the grocery store with $20 and leave out with about 35-40 items. As of now, you walk in the grocery store with $20 walk out with 3-5 items. During the 1960s the environments setting weren’t as bad as they are now. The crime rate isn’t as high as they are now. That’s why she chooses to leave out early in the morning to run arranges because she feels safer. The generations has changed and progressed in different ways. Things were easier than they are today. Before you don’t really worry about much, now some people fear to leave the comfort or their home. Maybe if I was alive during that time, I maybe would have gone through as much as I am today. If you had a chance to live in that time zone, would you?

Analyze compare and contrast two books Research Paper
Analyze compare and contrast two books - Research Paper Example John who is Ann’s mother and the Red Girl. Anne is the main character who dominates the whole novel and the story is told in her own subjective voice. The author depicts Anne as an arrogant and complex being who struggles to survive and define her own separate world from that of her mother. Anne is seen to develop as a character as she struggles with the fear of separation from her mother, becomes an expert in marbles and eventually develops hatred and anger as she rebels against her mother’s attempts to define her world (Kincaid 32). Mrs. John’s character is developed and defined by Ann through her subjective narration. She is initially portrayed as a person who is strong, wonderful, kind and full of knowledge about the societal norms and values. Anne develops bitterness and hatred towards Mrs. John when she repeatedly tells her that they are two separate beings. In addition to this, Anne points to her mother’s sexual relationship with her husband as the reasons for her alienation and neglect. The Red Girl on the other hand is developed as a character that represents the outside world and does not have to adhere to the societal norms and values. The Red Girl represents the new world which Anne dreams of creating and she becomes a key figure in Anne’s development as a character by offering her a sense of self. The major characters in The portrait of a young artist as a young man by James Joyce includes: Stephen Dedalus, Simon Dedalus, Emma Clery, Cranly and Charles Stewart Parnell. Stephen Dedalus, the main character in the novel, is developed as a highly sensitive individual. He has the advantage of a quality education but is portrayed to be living in isolation and deprivation amidst the oppressive colonial nationality, highly developed social immorality and extremist family and religious values. Just like Anne in Annie John by Jamaica Kincaid, Stephen feels trapped and seeks escape by abandoning the restrictive societal norm s and living freely as an artist. As a character, Stephen undergoes growth, development and transformation as the story progresses. His transformations occurs in various stages starting in his first year in college where he demonstrates that he is an intellectual person with his understanding of societal systems and begins to create a different perception of his environment (Joyce 32). Another transformation occurs when Stephen engages in sexual intercourse with the prostitute in Dublin which transforms his from innocence to promiscuity according to the societal values. The third transformation was motivated by Father Arnall’s speech regarding the concept of death and hell which led to his conversion from a sinner to a Catholic. His final transformation indicates his maturity as a conscious individual when he changes his obsession from religion and focuses on the appreciation of art and beauty. Thematic analysis Themes refer to the major topic or subject in a piece of literat ure. The themes in Annie John by Jamaica Kincaid include the relationships between mother and daughter, colonization and the impact of colonial education and the various gender relations in the society. The main theme is the relationship between mother and child where Kincaid develops the complex relationship between Anne and her mother in her childhood and adolescence. As a result of the closeness of their relationship, Anne encounters several challenges and tension as she

Stress in Law Enforcement Results in a High Degree of Divorce and Research Paper
Stress in Law Enforcement Results in a High Degree of Divorce and Suicide - Research Paper Example Indications suggest what can be done to alleviate the problems both individually as officers, within their families, and within the organization as a whole. Finally, the information covers law enforcement officers’ duties regarding service to the community and how the community can avoid a disservice to the officers. Key words: double bind, stresses, high risk lifestyle Stress in Law Enforcement Results in a High Degree of Divorce and Suicide. How does this Problem Develop and How is it Mitigated? Introduction â€Å"If you ever find me like that (shot), you better start looking for the one who did it, because I would never do that to myself (Boyce, 2006).†This was a statement previously quoted by a State Trooper who did not come home as usual after his shift. The officer was found with a gunshot wound to the head and sitting in his own car after a long and diligent search. The State Crime Lab determined that he had taken his own life. What would cause an officer to do such a thing to himself? Sergeant Boyce can remember seeing warning signs, after the fact, that the officer was under much physical and emotional stress (Boyce, 2006). The dead officer had become withdrawn and did not work with the rest of the officers as he had in the past. Sergeant James Boyce recalls himself when dozing in a chair at his home on the couch, and his wife or one of the kids touched him, he would sit straight up and make a fist as if ready to fight. Is an incident such as this caused by the everyday stress of law enforcement? (Boyce, 2006). According to Hans Selye, a respected researcher in stress, â€Å"police work is the most stressful occupation in America (Boyce, 2006).†Law enforcement stress leads to one of the highest, suicide rates in the nation in comparison to other occupations. The divorce rate for other occupations is 50 percent while law enforcement divorce rates are as high as 75 percent. This makes the divorce rate among police officers second i n the nation. These facts alone are a warning sign targeted at law enforcement management. Extreme Negative Effects Dan Goldfarb covers the impact of stress on police officers at a union delegates meeting. He defines stress in a very unconventional way, but it relates very well to the job of police work. Stress is â€Å"that feeling and desire along with the ensuing bodily effects, experienced by a person who has a strong and true longing to choke the living shit out of someone who desperately deserves it, but you can’t (Goldfarb, 2011).†It is Goldfarbs’ contention that although this might be a very funny way to convey the information, however, there is a real truth to it. Law enforcement work calls for an incredible amount of discipline and restraint. This restraint is a continuing thing and it causes insurmountable stress. Goldfarb points out that between 1934 and 1960 police suicide rates were half that of the general population and between 1980 and the pres ent have almost doubled (Goldfarb, 2011). So the difference in the present vs. the past is, â€Å"You can’t choke em anymore,†as he puts it. He contends that street justice no longer exists, the media is continually showing the negative side of police work, and politicians cater to the public and new laws, therefore, your hands are tied. So, law enforcement officers start to feel like they are being choked. According to research the biggest stresses for police work are, 1. Taking a life in the line

Anth2 Final Exam - Assignment Example Intimate relations of close family members or incest are usually regarded as a taboo which may be disastrous. 5. Family status influences gender role in that the conduct of single and married people is different. Ethnic culture is another factor that affects gender roles whereby certain ethnic backgrounds may be passive than others and vice versa. 7. Leadership in tribes is uncentralized due to lack or very little forms of stratification. In case stratification is present, the leadership in place determines its level. On the other hand, chiefdoms are centralized with highly regarded and exalted leaders. Therefore, the leader has more control over subjects in his domain more than at the tribe level. 8. Formal means of social regulation or control refers to the external undertakings by civil authority to deter development or establishment of anomie within the society. On the contrary, the informal means alludes to socialization which causes internalization of values that impart morally accepted behaviors within the society. 9. Both these rites have great importance attached to them because they usually bring the community closer when they are being undertaken. In this regards, they serve a means of improving relationships among people and creating harmony within a community. 10. One way in which religion and magic are similar is use of rituals. Rituals are actions or undertakings which are accompanied by vague chanting. Secondly, these two also have unique symbols that are both mystical and spiritual. These symbols are routinely used during the time of rituals. Besides, these two also believe in the contagion principle where there is continued connection and communication between two objects that had been in contact and are separated. 11. One of the functions of revitalization cults is to deliver the followers from deprivation which is political in nature. This is important for amelioration

Multiple Intelligence Theory Essay Example for Free
Multiple Intelligence Theory Essay Many students choose to attend APUS because the University fosters differing educational styles and empowers the students through education. The Student Handbook states, â€Å"The University System fosters an environment that promotes a life of learning for its constituents and uses feedback from its participants and supporters to improve the quality of its teaching, learning, and support†¦ The University System anticipates and adapts to its changing environment and responds to the needs of the organization and its constituencies in manners both appropriate and timely. †In the beginning of College 100, students are introduced to the different learning styles and the theory of multiple intelligences. By becoming familiar with other students learning styles and exploring the multiple intelligences students became more tolerant towards others and were able to strengthen their learning power. Being familiar with multiple intelligence theory, knowing the different learning styles, utilizing appropriate classroom methods, and exploring the interdisciplinary classroom will empower students towards a lifetime of learning. Recognizing the multiple intelligence theory is the first step in capturing the different learning styles. â€Å"Howard Gardners multiple intelligence theory (Gardner, 1993) proposes the idea that we all have various levels of intelligence across a range of intellectual areas†(Pritchard, 2008). The concept that people learn in different ways, and perceive and learn by different methods is what makes up the theory of multiple intelligences. There are at least nine different intelligences in which people display in varying ways (Pritchard, 2008). The styles are as follows: linguistic, logical/mathematical, musical, spatial/visual, kinesthetic, interpersonal, intrapersonal, naturalistic, and existential (Pritchard, 2008). Student’s particular academic strengths have a direct impact on how effective their learning will be for their overall education. When applying multiple intelligences to the classroom, it is very important to cater to all the types of learning styles. When discussing learning styles in the forums of College 100, every student had a different way of learning that especially worked for them. If every single assignment or activity in a classroom is slanted towards visual learning, then the students who are auditory or kinesthetic learners will be at a serious disadvantage. These students will not be able to express themselves or be able to conform to the teaching style if their learning needs are not met. â€Å"In planning for multiple intelligences, teachers consider the range of activities related to the content of the lesson and the intended learning outcomes will give a range of opportunities to the children’s different intelligence strengths†(Pritchard, 2008). It is very important for a teacher to introduce a range of activities and presentations in order to make the most out of multiple intelligences. A learning style is reflected by a students preferred method of learning, which is a direct result of their type of intelligence. It is irresponsible for a teacher to assume that all of their students will learn in the same manner. The four main styles of learning are visual, auditory, kinesthetic, and extrovert. Every style has strengths and weaknesses. It is crucial in the educational environment to exploit the student’s strengths and protect the weaknesses. A student’s self-worth and esteem can be very much tied up with their learning capability. Teachers must exhibit a range of teaching styles, so that their students learning styles will be compatible. â€Å"Diverse personalities impact relationships, motivation, and ease of learning in classroom and work environments. Where there are diverse personalities within groups, people generally prefer and choose to be with others who are similar to themselves; individuals may even dislike those who have different attitudes and behaviors from their own†(Richardson Arker, 2010). What Richardson and Arker are implying is that people of different personalities and learning styles tend to stick in the same groups. It would be to the benefit of everyone if individuals of different personalities and persuasions were put together in one group, that way the group will be more powerful and will benefit greatly from the input of everybody. A truly good teacher will ensure that they have designed their curriculum in such a way so that students learning needs are met. Classroom arrangements can be made so that individuals of similar temperaments are brought together in what is called compatibility scheduling. This arrangement will enhance the overall productivity of students as well as teachers†(Richard son Arker, 2010). As multiple intelligence theory has developed, advances in classroom methods have also been made. There are at least three different methods that combine multiple intelligence theory with learning styles in order to better the classroom environment. â€Å"Brain-based education supports the need to differentiate instruction†(Richardson Arker, 2010). Some studies in brain research have shown that there is such a thing as a left-brain and a right-brain. People can be left or right brain dominate, which largely determines the individuals learning style. â€Å"Collaborative learning is a method of teaching and learning in which student’s team together to explore a significant question or create a meaningful project†(Educational Broadcasting Corporation, 2004). This type of classroom learning will serve to help the entire group. The students and teachers will be able to pick out the roles that suit them best, thus serving the group to the best of their ability. Another method that is similar to collaborative learning is cooperative learning. In cooperative learning, â€Å"Students work together in small groups on a structured activity. They are individually accountable for their work, and the work of the group as a whole is also assessed. Cooperative groups work face-to-face and learn to work as a team†(Educational Broadcasting Corporation, 2004). Cooperative learning is becoming a very popular method. It uses individuals best qualities for the betterment of the group. By using these methods in the classroom learning becomes an active process and engages all types of learning styles. The Western world has divided education into blocks, and then further divided the blocks into disciplines. While convenient on paper, it is clear that education and disciplines overlap, the world is a fluid place. Interdisciplinary education is an approach that blends different disciplines and utilizes multiple intelligence theory and varying learning styles. â€Å"The exponential growth of knowledge in the twentieth century revealed how disciplinary cultures and perspectives could discourage inquiries and explanations that spanned disciplinary boundaries. Disciplines, it now seems clear, are powerful but constraining ways of knowing†(Lattuca, 2001). By breaking down the walls of the disciplines, students are empowered to use their differing learning styles. This will result in students having positive experiences with education. Students will then seek out a lifetime of learning, and encourage other to seek knowledge. Recognizing the theory of multiple intelligences and defining each student’s learning style will lead to success in education. By utilizing methods such as brain-based learning, cooperative learning, and collaborative learning teachers can empower students by giving them the educational method that works best for each individual. Combining all of these aspects yields the concept of interdisciplinary learning, leading to a lifetime of successful education, teaching, and learning. References Concept to Classroom: Course Menu.

Strategies for Breaking Wireless Protocols
Strategies for Breaking Wireless Protocols CHAPTER 1 INTRODUCTION 1.1 Background Starting of wireless Network is a result of a research Project carried out by University of Hawaii. Initially its called as Aloha net, but later it used to call as Wireless Local Area Network or WLAN. At the beginning of aloha net, is capable of transferring 1 to 2 mbps data. But over the last few years aloha net changed to WLAN and it came with so many enhancements to the initial technology. Newer days, wireless networks become more popular than the wired networks. The main reason for this is, wireless networks are high in portability and the flexibility, increased productivity, and lower installation cost. Wireless Network Devices let Users to move their laptops from one place to another without warring about their network connectivity. Minimizing the wiring gives the maximum flexibility over the network and it reduces the wiring cost for the whole network infrastructure. However, when we comparing the security factor, wireless networks are more vulnerable to attack by outsider than the wired network. Main reason for this is, anyone can see and make the initial connection through the wireless network. But establishing the initial connection in a wired network is bit difficult than the wireless network. Loss of confidentiality like password cracking and man in the middle attacks are typically associated with wireless networks. Some other way, this kind of attack can easily practise in wireless Networks rather than the wired network. Even though a wireless network has this kind of problems, its not a failed concept. The main reason for that is we can protect a wireless network in maximum and make invincible from unauthorised users or attackers. Configuring the wireless devices correctly and accurately can minimize the attacks. We are going to discuss about this topic in future. 1.2 Objectives Breaking wireless protocols is the main objective in this project. Mostly the WEP, WPA and WPA2 will be my major preference. So the goal of this research is break the wireless protocol and get data from the wireless devices and the network. 1.2.1 Comparison of Hacking Tools Available. There are lots of tools that can use to hack a wireless protocol. Some of the tools are very user friendly. We can install it on our Windows Based Systems and it does our work very easily. Those tools are 100% Graphical User Interface and very easy to use. AirCrack-ng Windows version is the common example. But Some Other tools are available; we need to have some technical knowledge to use those tools. Mainly those tools run on command base mode and running platform is Linux. These tools do not provide any graphical user Interface, and bit difficult to learn without any proper guidance. But the final result is very accurate than the windows version. The major difference between these two types of tools are the software which runs on linux is more accurate than the Windows version. So I have decided to use Linux version hacking software to carry out my testing. But to hack a wireless network we need few of software to download from the internet. And then we can install those on a Linux machine and we can start the research. But, I think its very easy to use a one operating System rather than struggling with lots of softwares. So I decided to download latest version of worlds famous Hacking Operating System â€Å"Back Track†. It has built in hacking tools that need to hack a wireless network. 1.2.2 Downloading related software. Back Track is free to download, and its open source. Anyone can download Back Track from its developers web site www.backtrack-linux.org for free. So I have downloaded the latest version of Back Track v4 to carry out my research. We will discuss about BackTrack in further chapters. 1.2.3 Cracking WEP Using AirCrack-ng In order to crack a WEP Password, I have chosen few amazing tool. That is BackTrack 4 Hacking Operating System. It has all the hacking tools to crack a WEP Network. Airodump-ng can use to get the information about the wireless network and then I can use the Aircrack-ng to crack the password. 1.2.4 Cracking WPA Using AirCrack-ng We Can Use the same Process to Crack the WPA using AirCrack-ng. Same as in WEP I am going to use the Airodump-ng and Airoreply-ng to collect all the informations about the wireless Network and AirCrack-ng to decrypt the Password. 1.2.5 Cracking WPA2 Using Cowpatty In here, I am going to use a special cracking Software to crack WPA2. The software is Cowpatty. Cowpatty bit different than Aircrack-ng. And cowpatty specially designed to crack WPA and WPA2 Passwords. All these tools are built-in tools which we can find in the BackTrack4 Linux based operating system. So I dont need to download these softwares from the internet. 1.3 Dissertation Structure This Documentation mainly divided in to 4 Main Chapters. Including entire Practical and theoretical concepts. Chapter 1: Introduction In this section, I am going to give a introduction about what is wireless Network, Start of the Wireless Network and Basic Problems that wireless Networks faced. In the Second Section explain about the whole Research objectives and aims. Chapter 02: Literature Review This Chapter Consist all the theoretical informations relating to my research. In here I am discussing about wireless Networks and its Types, Wireless Network Devices, Security Methods that WLAN Uses, WLAN Security Protocols, Deep discussion about WEP, WPA and WPA2, Protocol Hacking tools like Air Crack-ng, Cowpatty, and Hacking Methods that use by the Hacking tools. Eg: Dictionary Attacks, Brute Force Attacks etc. Chapter 03: Methodology In here, I am going to show my Practical Work that I have done all over my research. Installing the Hacking OS, Use of Hacking tools, Problems Faced all over the project and the final results will be my main concerns. Chapter 04: Result and Discussions In this section I am comparing all the results I have gain all over my project. Chapter 05: Conclusions This Chapter will be my conclusions of the Research. In here i am planning to compare my final result and the objectives in my initial project proposal. CHAPTER 02 Literature Survey 2.1 Wireless Networks Wireless Networks enables to communicate devices without any physical media. These Networks are divided to three main categories according to their communication level. Those are, Wireless Local Area Network, Wireless Wide Area Network, Wireless Personnel Area Network. Wireless Wide Area Network has larger coverage than the WLAN and WPAN. WWAN uses 2G or 3G Cell Phone Networks to connect each and every device in the network. WLAN represents local area network that connected using wireless access point or a wireless router includes 802.11. WPAN is a small network topology. This includes Bluetooth and Infrared technologies. 2.1.1 Wireless Local Area Networks As I Mentioned earlier, Wireless LANs has more portability and flexibility over traditional Wires Local Area Networks. In WLAN, All the Computers and other devices connect to each other using Wireless Access Points also called as APs. And Access points communicated with the Wireless Network Adaptors that fixed in to computers. Access Points normally has coverage are up to 75-100 meters. In that area users can move their laptops and other wireless devices while maintaining their network connections. We can connect access points together and expand the wireless LANs coverage. In my thesis, I am going to discuss more about wireless LAN in further chapters. 2.1.2 Wireless Wide Area Networks This is the most familiar wireless Network type for everyone. This networks are Combinations of few WLANs. In these networks, Antennas acts as the access point for all WLANs. There are connections between Antennas to Antennas, to expand the Service of the network. Mobile Phone Networks also a good example for WWAN Networks. 2.1.3 Wireless Personnel Area Networks These Networks are so smaller when comparing to the other networks. It does not give much coverage as other 2 network type we discuss earlier. And this network does not require Main Access Point to make the connection with other WPAN Devices. Source WPAN device directly connect to the other WPAN device when its needs to transfer data. 2.2 Wireless Local Area Networks This is the most important topic of my thesis. We are going to discuss about this topic all over the project. As I mentioned in my objectives I am going to analyse the security of WLAN and Break few of WLAN Protocols. Before that we need to get a clear Idea about â€Å"What is WLAN?†and â€Å"How it operates?†WLAN is same as the wired Local Area Network. But the only difference is, its using wireless method to connect all devices. WLAN combined with the Client Station and the Wireless Access point. The Client Station connects to the AP (Access point) using the wireless Network Adaptor. We can connect the wireless adaptor to the computer using Personal Computer Memory Card International (PCMCIA) slot or using the USB Port. IEEE 802.11 is the Standard of WLAN technology. The coverage of the Wireless network totally relay on the Strength of the Wireless Access Point. Normally its can covers up to 75-100 meters circular area. 2.2.1 Architecture of 802.11 Standards This architecture allows initiating a peer to peer connection between Client Station and the wireless Network based on access point in an infrastructure network (WLAN). The coverage area of an access point called as a â€Å"Cell†. A Cell also called as â€Å"Basic Service Set†(BSS). The collection other cells of the infrastructure network called as Extended Service Set (ESS).Any access point that work with 802.11 standards has this 2 data sets for their functionality. BSS is the most important data set in the Access point. BSS contain all the information about wireless Network. This is the security key negotiation protocol of the Access point. BSS consist of APs Hardware name, Communication protocol informations, Signal strength etc. The Access Point identify in the WLAN using a specific identifier. This is called as â€Å"Basic Service Set Identifier†(BSSID). When Laptop or any other wireless device needs to connect to wireless network via access point, the guest station (Eg: Laptop) searches for the available access points in the area by releasing discovery packets. If there any access points available, APs respond to the guest station by sending the BSSID. Normally BSSID is in a Human Readable format. BSSID also called as â€Å"AP Name or Router Name†by Technical personals. This identifier always represents a Specific Access point. Likewise each and every access point of the network has its own BSSID. NOTE: BSSID is very important to accomplish my main objective of the project. We need to retrieve the routers BSSID before we crack the routers password. We can discuss about the retrieving methods in future chapters. 2.2.2 Advantages of WLANs Following are the advantages. Increased Mobility- Users can be mobile while accessing to all the network resources. Fast Installation Installation of the network is very quick since there no adding wires like wired network. Flexibility anyone can easily install and uninstall a small wireless Network. 2.2.3 Wireless Protocols Use in Wireless Networks There are 3 main wireless protocols use by the 802.11x wireless networks. Those are, Wired Equivalent Privacy This Protocol primarily protect the WLAN uses being a victim from eavesdropping. WEP uses 64 bit RC4 key to generate encrypted data and then those encrypted data transferred over the network. Wi-Fi Protected Access This is introduced by the Wi-Fi Alliance to overcome certain restrictions in WEP. This uses Temporal Key Integrity Protocol (TKIP) to encrypt the wireless data packets. Wi-Fi Protected Access Version 2 This is the latest movement in wireless LAN Protocols. Only the Difference is WPA 2 introduces new AES algorithm to be much more secure than the WPA. These 3 protocols widely using in wireless Networks. Every protocol has significant advantages and disadvantages. In the next chapter I am going to illustrate features, advantages and disadvantages of each and every protocol. 2.2.4 Wired Equivalent Privacy (WEP) WEP is an authentication protocol that use in 802.11 wireless networks to secure all the transmitting data. This protocol introduced in 1997 and main intention was increasing the confidentiality of the data than wired network. Any wireless network that uses WEP encrypt the data packets using RC4 cipher stream generated by a 64 bit RC4 key. IEEE 802.11 has few basic features when it comes to Security. These concerns provide a better security for the wireless environment. This all security elements embedded in to the wireless network protocols. Following are the basic security concerns in a wireless Network. Authentication This is the main goal of the wireless protocols. This means identifying the Client Station by using a password. If any client station failed to comply with this requirement the AP will deny giving the access to the Client Station. Integrity In here, the data should not be changed while it transmitting from the AP and/or to the AP. That mean those data should not be a victim of active attack. Confidentiality in this goal, the Protocol should protect the security of all data elements that transmit. In other word, the data should not be a victim of passive attacks. 2.2.4.1 Authentication 802.11 Networks have 2 kinds of authentication methods. â€Å"Open System Authentication†and â€Å"Shared Key Authentication†. 802.11 Authentication Open System Authentication Shared Key Authentication Any Client Station can join The Station should Provide the To the network without authentication Network password in order to join Network In Open system authentication does not use any cryptographic password to gain access to the network. Any client station can connect to the network and use the network resources. As an example, Internet facilitys in a public locations like Air Port or a Bus Station. In these places anyone can connect their Laptop or PDAs to the Wireless Access Point and start browse the internet. No Password required at all to login to the network. In open system method, the client station sends its MAC address just as a reference to the Access point. Then the AP makes that client as a member of that APs network. The major problem with this authentication mode is its vulnerable to attack. Shared key authentication is password based authentication model. The client must have the password to make the connection with AP. when client made a request to the AP that asking the connection, the AP generate a challenge and send it to the client station. If the client station responds to that challenge correctly AP gives the permission to be a member of wireless network. Figure 2.7 give the clear idea about the Shared Key authentication. Authentication Request Challenge Response Confirm the Result 2.2.4.2 Integrity 802.11 Standards also concerns about the integrity of the data transmitted. This always checks the data content whether it got changed while happening the transmitting process. It uses Cyclic Redundancy Check (CRC) approach to check the content of data. Once the CRC completed those data encrypted by using the RC4 key Stream. On the receiving end, data will be decrypted and again check for CRC to check the integrity of the data. If the receiving end CRC value does not match with the initial CRC value the data will be rejected and retransmitting will be required. WEP Uses an algorithm called Stream Cipher to encrypt all the data. It expand short version of key in to a random key stream. The sender encrypts the Plain text along with the Short key and creates the cipher text. In the receiver end has the same short key to decrypt the data. Once the data stream received by the recipient, it uses the short key to generates cipher text back to plain text. If one data bit lost on its way to the destination, the decryption process will mislead the data in to incorrect information. To prevent this problem WEP has â€Å"Cyclic Redundancy Check†to keep up the Message Integrity correctly. 2.2.4.3 Privacy 802.11 standards use cryptographic techniques to support Privacy. It uses RC4 Symmetric Keys to protect the data. Normally 802.11 standards support different cryptographic key lengths to protect the data from a attack. Generally, WEP supports 40 bit cryptographic key size for the shared key. But numerous vendors support different key sizes like 104 bits and 128 bits. Increasing the key size increases the security of the cryptographic technique. 2.2.4.4 Problems with WEP Even though WEP has so many security measurements to protect the transmitting data, it has few failures. These failures make the way, an attacker to break the security of WEP and lost the Integrity and privacy of the transmitting data using WEP. 2.2.4.4.1 Shared WEP Key WEP Uses single security key to Access the network. So this key should be distributed to all the users who access the network. So this security key might go to an attacker very easily who trying to get the access to the network. 2.2.4.4.2 WEP Key Size As I mentioned earlier, WEP uses 40 bit Cryptographic Key Size. This key can be crack very easily regardless of the time. So the encryption key is not sufficient to provide a better security for data. 2.2.5 Wi-Fi Protected Access This is a WLAN protocol created by the Wi-Fi alliance. This is created because of several weakness of the WEP Protocol. WPA has some advanced features when comparing with WEP. To get the optimum performance from the WPA, The WPA protocol implements the majority of the IEEE 802.11i standard, and was intended as an intermediate measure to take the place of WEP while 802.11i was prepared. Specifically, the Temporal Key Integrity Protocol (TKIP), was brought into WPA. TKIP could be implemented on pre-WPA wireless network interface cards that began shipping as far back as 1999 through firmware upgrades. Because the changes required fewer modifications on the client than on the wireless access point, most pre-2003 APs could not be upgraded to support WPA with TKIP. Researchers have since discovered a flaw in TKIP that relied on older weaknesses to retrieve the key stream from short packets to use for re-injection and spoofing. [wiki/WPA] 2.2.5.1 Features of WPA WPA uses Temporal Key Management (TKIP) as its Key encryption system. WPA does, Data Encryption and Discretion based on TKIP technology. It uses 128 bits for encryption using RC4 cipher. 2.2.5.2 Temporal Key Management TKIP along with the WPA has introduced three security features to overcome some security issues that come with WEP networks. TKIP mixing the security key with the initialization vector before it pass it to the cipher routine. In our case TKIP uses RC4 as the cipher. This method avoids certain kind of key attacks that came along with WEP. And then, WPA protects the data packets against reply attacks by implementing a sequence counter to the data stream. Finally its implements a message integrity check called â€Å"MIC†to check the consistency of the data stream. As i mentioned earlier, TKIP uses Rivest Cipher 4 (RC 4) as its cipher. Rekeying, also an important feature of TKIP. And the most important feature is TKIP always ensure to send data with a Unique Encryption key. But in certain situations it uses same mechanism like WEP. So TKIP also vulnerable to some kind of attacks which WEP faces. Any how the advance development of Message Integrity Check, Isolated Key Hashing on every packet, Sequence Counter prevents those attacks successfully. The Best thing is TKIP resolving most of the problems came along with the WEP. The next section discuss about that. 2.2.5.3 Michael Message Integrity Code Unlike WEP, WPA uses special feature to check the integrity of the transmitted message. This is called as Message Integrity Code (MIC). This is also called as Michel. This is a short cryptographic checksum that use to authenticate a message. This is also known as Message Authentication Code (MAC). This is a 64 bit algorithm that controls several types of attacks like, Splicing Attacks, Payload Truncation, and Fragmentation Attacks. 2.2.5.3 Extensible Authentication Protocol (EAP) EAP is an Authentication Method that widely use in wireless networks. This is not specifically designed for wireless networks. This can be use to authentication in wired network as well. EAP use to transmit the packets containing Authentication informations. WPA and WPA2 Networks supports 5 EAP Authentication Mechanisms as it Authentication Standards. Those are, EAP-TLS, EAP-SIM, EAP-AKA, PEAP, LEAP. 2.2.5.3.1 EAP-TLS EAP-Transport Layer Security is well known among Protocol for wireless communication. TLS provide very strong confidentiality for the User Credentials. This uses PKI to secure the communication between the AP and the RADIUS Server. EAP-TLS is the original, standard wireless LAN EAP authentication protocol. Although it is rarely deployed, it is still considered one of the most secure EAP standards available and is universally supported by all manufacturers of wireless LAN hardware and software. [Wiki/EAP] A compromised password is not enough to break into EAP-TLS enabled systems because the hacker still needs to have the client-side private key. The highest security available is when client-side keys are housed in smart cards. This is because there is no way to steal a certificates corresponding private key from a smart card without stealing the card itself. [Wiki/EAP] 2.2.5.3.2 EAP-SIM EAP for Subscriber Identity Module used for authentication and Session key distribution using the Global System for Mobile Communication (GSM) SIM. [Wiki/EAP] 2.2.5.3.3 EAP-AKA EAP for Authentication and Key Management Agreement is used for Authentication and session key distributing using the Universal Mobile Telecommunication System (UMTS). [wiki / EAP] 2.2.5.3.4 PEAP PEAP is a joint proposal by Cisco Systems, Microsoft and RSA Security as an open standard. It is already widely available in products, and provides very good security. It is similar in design to EAP-TTLS, requiring only a server-side PKI certificate to create a secure TLS tunnel to protect user authentication. [Wiki/EAP] There were two PEAP sub-types certified for the updated WPA and WPA2 standard. They are: PEAPv0/EAP-MSCHAPv2 PEAPv1/EAP-GTC The terms PEAPv0 and PEAPv1 refer to the outer authentication method, the mechanism that creates the secure TLS tunnel to protect subsequent authentication transactions. EAP-MSCHAPv2, EAP-GTC, and EAP-SIM refer to the inner authentication method which facilitates user or device authentication. [Wiki/EAP] 2.2.5.3.5 LEAP The Lightweight Extensible Authentication Protocol (LEAP) A proprietary EAP method developed by Cisco Systems prior to the IEEE ratification of the 802.11i security standard. [Wiki/EAP] LEAP uses a modified version of MS-CHAP, an authentication protocol in which user credentials are not strongly protected and are thus easily compromised. Along these lines, an exploit tool called ASLEAP. [wiki/EAP] 2.2.6 Wi-Fi Protected Access 2 WPA 2 implements IEEE 802.11i standards same as the WPA. WPA 2 supports Advanced Encryption Standards as the encryption cipher. This is an encryption standard that implement by US Government. 3 block of ciphers available in the AES. Those are AES 128, AES 192, and AES 256. In WPA2, Advanced Encryption Standards using counter Mode-Cipher Block Channing to provide the high confidentiality to the data. [Microsoft] WPA2 architecture must contain following network components to provide better security to the network. An Authentication Server to authenticate the users, Robust Security Network to maintain the pathways of associations, and AES based methodology to provide the privacy, integrity and authentication. The authentication server holds all the user name and passwords of the users of wireless network. When a user wants to connect to a network that uses WPA, The User must provide His / her identical user name and password when the network asks for it. Then the AP sends that informations to the Authentication server to verify the validity of the user to access network resources. Once the authentication server gave a positive feedback, the user allows connecting to the network otherwise the request will be discarded. 2.2.6.1 The Four way Hand Shake The Authentication Process has 2 Parts, the access point (AP) still needs to authenticate itself to the client station (STA), and keys to encrypt the traffic need to be derived. The earlier EAP exchange has provided the shared secret key PMK (Pair wise Master Key). This key is, however, designed to last the entire session and should be exposed as little as possible. [1] Therefore the four-way handshake is used to establish another key called the PTK (Pairwise Transient Key). The PTK is generated by concatenating the following attributes: PMK, AP nonce (ANonce), STA nonce (SNonce), AP MAC address, and STA MAC address. The product is then put through a cryptographic hash function. [1] The handshake also yields the GTK (Group Temporal Key), used to decrypt multicast and broadcast traffic. The actual messages exchanged during the handshake are depicted in the figure and explained below: [1] 2.2.6.2 Group Key Hand Shake The GTK used in the network may need to be updated due to the expiry of a preset timer. When a device leaves the network, the GTK also needs to be updated. This is to prevent the device from receiving any more multicast or broadcast messages from the AP. [2] To handle the updating, 802.11i defines a Group Key Handshake that consists of a two-way handshake: [2] The AP sends the new GTK to each STA in the network. The GTK is encrypted using the KEK assigned to that STA and protects the data from being tampered using a MIC. The STA acknowledges the new GTK and replies to the AP. [2] 2.3 Differences between WEP, WPA and WPA2 2.3.1 Encryption Methods WEP uses only one encryption method for the whole network, but in WPA, encryptions are dedicated for every user. One user has its own encryption method. 2.3.2 Authentication In WEP Authentication, it uses Open or Shared key authentication method. In WPA operates on Pre-Shared Key Method. As well as WPA uses an authentication server to validate the user and it using EAP to send all the informations to the Server. But WEP does not use any authentication server. 2.3.3 Security Protocols and Key Streams WEP uses WEP as their Security protocol. This is a primary wireless protocol that has few loop hols for attackers, in WPA use Temporal Key Integrity Management as the security protocol. WPA 2 uses bit advanced security protocol than both of the WEP and WPA. It uses Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP). WPA and WEP both use Rivest Cipher 4 as their cipher, but WPA 2 uses Advanced Encryption Standards. WEP uses 40 and 104 bits key length for the encryption key. WPA use 128 bit for the encryption and 64 bit for the Authentication. WPA2 uses 128 bit key streams for the both Encryption and the authentication. 2.3.4 Data Integrity and Key Generation WEP use Cyclic Redundancy Check 32 bit Method to check the Integrity of the data. WPA use Michael Message Integrity Code to check the integrity of data. WPA2 has CBC-MAC for that operation. WEP does the key generation by using Concatenation. In WPA used â€Å"Two phase mixing function (both TKIP and RC4)†. WPA2 doesnt require any key generation. 2.4 Security Threats Associated with Wireless Networks As Discussed above, nowadays wireless networks become more popular than the wired networks. Many organisations including Commercial Companies, Hospitals, government offices and most of the houses use wireless networks to facilitate different services. But the problem is WLAN are not 100 percent protective from attacks. 802.11x networks are vulnerable to certain attacks. There are thousands of papers and reports available in the internet that describes those kinds of attacks and security threats to WLANs. These security threats mainly target on Confidentiality, Integrity and Network availability. WLAN attacks normally divide in to 2 types. Those are â€Å"Active Attacks†andâ€Å"Passive Attacks†. Then those 2 main classes sub divided into types of attacks. 2.4.1 Active Attacks Active attacks are the most dangerous attack type. In here, hacker or the unauthorised party gain access to the system and do the modifications to the system or the message transmitting. This outcome a receiving an incorrect message stream or a file to the recipient. Active attacks result a loss of integrity of the network. Active attacks are possible to detect by using special software like packet monitors. But the problem associated with this kind of attacks are, its difficult to prevent these kinds of attacks. Active attacks can be sub categorised in to 4 Methods of attacking. Following explain those, 2.4.1.1 Masquerade In here, Attacker imitates as an authorised user in the network and gains the access to the network. This kind of attacks can be happened in few ways. The first consideration is authorised user give away the password to an unknown person or a group of people. So automatically they are possible to get access to the system. The other consideration is hacker can use some software pieces to collect the passwords or access keys of authorised users. There are many methods to perform this kind of attack. Installing Key Board Activities Recording software is a very successful method to collect these kinds of informations. 2.4.1.2 Reply The Attacker can monitor the transmissions of the source and destination machines and re transmit the informations as a legitimate user. So the attackers computer acts as the Source and destination accordingly, to get the actual source and Destinations informations. Reply attacks are offline attacks. The attacker first gathers all the data and then later decrypts that information. This informations could be users authentication session informations that carries WLAN password. 2.4.1.3 Message Modification In here, attacker tries to modify a particular message or informations. This could results a transmitting wrong informations to the legitimate user. 2.4.1.3 Denial of Service This is a very popular attack type and very easily does in a WLAN environment. The main goal of this attack is make the network unavailable to the users. it generally consists of the concerted efforts of a person or people to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely [wiki]. This attacks cause Loss of Network a
