The Falling Apart of Okonkwos Personal Life and the...

Things Fall Apart. Such an intriguing title, because everything will eventually fall apart. Chinua Achebes choice of a title may lead some to confusion, because throughout his book many things fall apart, from Okonkwos personal life achievements and emotions to the town of Umuofia as its people split, and perhaps the biggest thing to fall apart, the very culture of the Igbo people. One could focus on any one of these topics and trace the complexity of its fall from previous glory to the eventual ruin at the end of Achebes novel. Studying the overall book provides a much more interesting conclusion, however, than simply tracking the different ways people or the town change, as instead it is possible to gain insight into Achebes goals†¦show more content†¦Okonkwo started with what his father, Unoka, had left him. Unoka left the legacy of his son [...] was ashamed of him (Achebe 8.) He left Okonkwo [having] taken no title and [being] heavily in debt (8.) However, Okonkwo was ab le to rise above his being ashamed of his father, because despite being left heavily in debt he had become a wealthy farmer (8) and despite his father not having any titles, he had won fame [...] and he had taken two titles [...] he was already one of the greatest men of his time (8.) Okonkwo was able to become successful, despite the disgrace his father had left as his legacy, and because of this Okonkwo received a boy to take care of, Ikemefuna. However, when Okonkwo must allow the boy to be killed, he sabotages his own emotional health by going with the execution party. This moment shows how Igbo culture was not perfect, as this is not a problem within the culture caused by Europeans, but is just an unfortunate part of what their traditional culture is. Okonkwo was warned by Ogbuefi Ezeudu, a man considered wise and given high respect, to not kill that boy because he calls [Okonkwo] father (57.) Oknonkwos own insecurities are highlighted just as Ikemefuna is about to be killed, w hen Ikemefuna cries, My father, they have killed me! as he ran towards [Okonkwo]. Dazed with fear, Okonkwo drew his machete and cut him down. He was afraid of being thought weak (61.) Okonkwo

From the Inside Out To Kill a Mockingbird Essay - 585 Words

Twenty-seven years in prison could not shake his resolve to transform laws in South Africa. Innocent people shot down in front of him did not scare him away. After his death, NBC News reports that â€Å"†¦Mandela was a figure of enormous moral influence—a symbol of revolution, resistance, and triumph over racial segregation† (Connor). Similarly, Harper Lee shows us in To Kill a Mockingbird that one person standing alone has the power to influence the minds of people and challenge them to make sensible decisions. There will be many obstacles to overcome but one person can change society’s actions by taking courage to stand up for what’s right and urge other people to view situations differently. Society will not change itself unless someone†¦show more content†¦With the new information, they are able to look deeper into the situation, but also open up to see other opportunities. When a mob of grown men arrive, Scout starts talking to Walter Cu nningham about his son and entailments. Atticus reflects afterwards that â€Å"†¦you children last night made Walter Cunningham stand in my shoes for a minute. That was enough† (Lee 157). A young girl standing in the middle of a hostile mob talks to everyone without a clue of what is happening and made them realize how things looked from her father’s point of view. When the men further understood their actions, they changed their mindset. After explaining why he pretends to be drunk all the time, Mr. Raymond tells Scout and Dill that in the future they will â€Å"cry about the hell white people give colored folks, without even stopping to think that they’re people, too† (Lee 201). The children are too young to realize the trouble white people create for colored people because they are so focused on skin color and outward appearances. He wants white people not to look at colored people as colored, but rather as a human just like everyone else. If othe rs are exposed to unfamiliar ideas, they will view the world at a different angle and their actions will change with their thoughts.

Track Presumption Reproduction Of Desire -Myassignmenthelp.Com

Question: Discuss About The Track Presumption Reproduction Of Desire? Answer: Introduction: In the last few years there has been one industry which has been responsible for the centre stage of business which is that of e-commerce. Online marketplaces are responsible for a major amount of shopping which is being done. Several small, medium and large companies have succeeded from the growth of e-commerce. The sellers are also experiencing a significant accounting of growth in the business. It is considered that e-commerce is one of the biggest business opportunities in the present times. Out of several e-commerce transactions, the B2C is responsible for directly connecting the business to the customer. It is a sort of transaction where a company sells its products or services directly to the customers, that is, the consumers (Haucap and Heimeshoff 2014). In the present report the selected application is the eBay application. The launch of the eBay application for both the android and the I-phone platforms has been a significant step in the success of the company all over the world. The report aims to show the decision of the eBay company and its decision to launch the application. The success as well as the existent drawbacks of the application as a mobile application is to be discussed in the report. The application can be considered a business to customer, that is, a B2C mobile application (Denegri-Knott and Zwick 2012). Background: The eBay company was launched in the year 1995. At the time of its launch it was an online platform which allowed the proficient peer-to-peer trading in the form of a public sale. The online auction site helped the people with a space on the internet for buying selling and trading any possible items imaginable. The business of the company is innovative in the sense that there is no amount of inventory, transportation and cost of production concerned with the products. There is a simple user environment of the product on both the application as well as the web page. The selling price for each of the items is posted and is provided as a total to the individuals and the company gets only a small portion of the selling price (Denegri-Knott and Zwick 2012). In the beginning the company planned to match up to the buyers and sellers. This would be matched up to the buyers and sellers by the collection of a nominal amount as a fees and this would help the business grow in a swift manner. The market of eBay provided an option for the transaction related to the products which did not have conventional stores. The company aimed to create the largest trading community of the world. Thus people could expand in the global market by a decentralised value chain implementation (Denegri-Knott and Zwick 2012). In order to maintain the supremacy of the company, it needed to have an impact on the minds of the people. The company understood that in the present world of technology it was necessary to maintain a connection with the people by all the social media as well as mobile application platforms (Patel and Menon 2013). The company is a cutting edge in commerce by the selling of almost everything dependent on its presence in any part of the world. Despite the fact that the company does not have any physical store it has a presence in every corner of the world. The growth of social media has impacted the way in which the organisations communicate, the internet also provides several ideas which enables a person to develop social and business platforms, share knowledge as well as collaborate (Lau and Bruno 2012). The constant connection and remaining updated about all sorts of happenings, on the social networking sites has proved to be beneficial for the company as they can remind and update their followers constantly about the uses, importance and capabilities. As the cell phones are connected to the social networking sites the organisations are able to ensure that their advertisements are always in sight (Liu, Cao and Wong 2013). The eBay company has utilized the internet known as digital marketing, web marketing as well as online marketing. The mobile phones which are nowadays used by people of all age groups, assist in the marketing of eBay. The users of the eBay services are notified in case of new notifications. The social media sites are also linked to the company services for notifying the customers (Lau and Bruno 2012). The application of eBay: The mobile applications of eBay are free and downloading the applications takes only a few minutes. The downloading of the application is often faster over Wi-Fi than on a cellular connection. So in order to ensure that the installation of the application is fast, the device needs to be connected to a wireless network. For i-phone or i-pad the application is to be downloaded from the app store and the search icon needed to be tapped and then the eBay for mobile or i-pad needs to be searched for (Lau and Bruno 2012). For android phones the items can be bought from the Android market by searching for the official eBay for android app and it needs to be installed. The items can be bought on eBay from the mobile device by simply downloading one of the mobile applications. In case a person has a different phone, eBay can still be accessed by utilization of the web browser, on the phone or Laptop. In the eBay applications, a person can perform a plethora of things (Einav et al. 2014). People can research sales trends and complete listings, for items which are of a same nature. This is to be done so that the products listed on the website of the company are competitive in terms of pricing. There might be pictures that can be taken from the device, and they can be added to the listing. It is fast and easy as well (Liu, Cao and Wong 2013). The items barcode can be scanned and the product available in the catalogue can be added automatically. The application is simple and easy to use. The menu on the mobile phones as well as other browsers clearly helps the customers to buy and choose products of their choice. The visitors on the application can clearly navigate through the application and the products to be purchased can either be selected directly or can be searched by using a special feature (Sondhi et al 2017). Sufficient description of each and every kind of product is provided in the application. The product is extremely beneficial for all kinds of consumers. In case of the application, the consumers can finish a listing they have started before and it can be either done on the mobile device or on the computer or laptop. The eBay application is synchronised to the eBay website. This makes it easy to allow proper synchronization and creating of listing. (Dalmasso et al. 2013). The preferences can be saved as also be predefined and these include the handling time and also return policy. The PayPal can be accepted as a method of payment. The active listings of the individual users can be tracked and the items can also be relisted. The tracking information can be provided to the buyers and questions can also be responded to at once (Garratt, Walker and Wooders 2012). With enhanced data driven marketing capabilities, eBay primarily focuses on making the email marketing of the company super-individualised and relevant. The daily deals which are set up for individual users are based on new deals each day (Lau and Bruno 2012). At first the customer deals were not personalised or relevant but at present the reminders of relevant items are sent to users thereby providing them with an update of items that they are viewing and which are best suited and available to them. However the application is not perfect and the drawbacks of the customers need to be listened to and worked on (Haucap and Heimeshoff 2014). Conclusion: From the given study it is clear that the decision of the company to have introduced the application for eBay was a reasonably good decision and the approach has been profitable. The development of the application for the iOS and android has assisted the operations in having a strong hold on the market. The application of the company provides several facilities which are otherwise not available in the conventional websites of the company. The company can also branch out to other business opportunities. The customers who have been loyal to the company for long time need to be retained. It can be ensured that the company has a personal buying and selling business. The company needs to look out for its competitors in the field and therefore it is desirable that application needs to improve the application and its features for being appealing to even more customers. The application needs to be even more user friendly and the company needs to improve its strategy to make significant improvements. The company therefore needs to focus on its negatives so as to emerge as an invincible player in the online market. References: Dalmasso, I., Datta, S.K., Bonnet, C. and Nikaein, N., 2013, July.

World War I Essays (1661 words) - World War I, French Third Republic

World War I Europe avoided major wars in the 100 years before World War 1 began. In the 1800's, the force of nationalism swept across the continent that helped bring about the Great War. Nationalism was the belief that loyalty to a person's nation and its political and economic goals comes before any other public loyalty. . Nationalism led to the creation of two new powers, Italy and Germany. War had a major role in achieving nation unification in Italy and Germany. Nationalism weakened the eastern European empires of Austria-Hungary, Russia, and Ottoman Turkey. Rivalry for control of the Balkans added to the tensions that erupted into World War I. Another thing was the assassination of Archduke Francis Ferdinand by a Serbian terrorist named Gavrilo Princip. On June 28, 1914 Archduke Francis Ferdinand was assassinated The Archduke's assassination triggered the outbreak of World War 1. A month later, Austria-Hungary declared war on Serbia. Because of Austria-Hungary's alliance with Germany, Serbia seeked help from Russia. Russia vowed to stand behind Serbia, but first Russia gained support from France. Germany declared war on Russia on Aug. 1, 1914. Two days later Germany declared war on France. The German Army swept into Belgium on its way to France. The invasion of Belgium caused Britain to declare war on Germany on Aug. 4. Germanys plan for a quick defeat of France while Russia slowly mobilized was called the Schlieffen Plan. This plan called for two parts of the German army to crush the French army in a pincers movement. A small left wing would defend Germany along its frontier with France. A much larger right wing would inv ade France through Belgium. They would then encircle and capture Paris, and them move east. On August 2 the German government informed the government of Belgium of its intention to march on France through Belgium in order, as it claimed, to forestall an attack on Germany by French troops marching through Belgium. The Belgian government refused to permit the passage of German troops and called on the signatories of the Treaty of 1839, which guaranteed the neutrality of Belgium in case of a conflict in which Britain, France, and Germany were involved, to observe their guarantee. Britain sent an ultimatum to Germany demanding that Belgian neutrality be respected. When Germany refused, Britain declared war on it the same day. Belgium's army fought bravely but held up the Germans for only a short time. By Aug 16, 1914, the right wing of Germany could begin its pincers motion. It drove back French and British forces in southern Belgium and swept info France. But instead of swinging west a round Paris, one part of the right wing pursued retreating French troops toward the Marne River. This move left the Germans exposed to attacks form the rear. Nationalism encouraged public support for military build-ups and for a country's use of force to achieve its goals. By the late 1800's, Germany had the best-trained army in the world. In 1898 Germany began developing a naval force that was big enough to challenge the British navy. Advances in technology helped aid in making military forces stronger. Machine guns and other new arms fired more accurately and more rapidly than earlier weapons. By the end of the 1800's, technology enabled countries to fight longer and bear greater losses that ever before. A system of military alliances gave European powers a sense of security before World War 1. They formed these alliances with each other for protection and guarantee that other members of the alliance would come to the country's aid if attacked. Although alliances provided protection, the system also created certain dangers. If war came, the alliance system meant that a number of nations would fight, not only the two involved in a dispute. Alliances could force a country to go to war against a nation it had no quarrel with. The terms of many alliances were kept secret. The Triple Alliance was made up of 3 countries: Germany, Italy, and Austria-Hungary. They all agreed to go to war if attacked by Russia. . Bismarck also brought Austria-Hungary and Germany into alliance with Russia. The agreement was known as the Three Emperor's League. They all agreed to

Were the British Empire’s Influences and Actions in Africa Good or Bad Essay Example

Were the British Empire’s Influences and Actions in Africa Good or Bad Essay Example Were the British Empire’s Influences and Actions in Africa Good or Bad Essay Were the British Empire’s Influences and Actions in Africa Good or Bad Essay Were the British Empire’s influences and actions in Africa good or bad? The British Empire controlled the Southern Africa for a long time until all the colonies of British started to rebel and get independence. Africa got their independence from British too. After the British left, the Africans started to organize and develop. The British left both good and bad impacts to the Africans. In earlier times, British had already invaded the coasts of Africa and started to â€Å"traded† with the Africans.Actually, they traded useless things to Africans, such as plastic, glass. And they took things which were much more valuable from them, such as gold, wood and other resources. Later, when the British was running through the industrial revolution, the technology, medical, army, navy were more advanced and organized comparing with the old times. They had over come the illness in the deeper places of Africa and started to send armies, navies to conquer more areas in the southern Africa.Then the British ruled the blacks and didn’t trade with them. They just took everything they wanted back to British. They caught slaves to sell or trade with the other countries. They thought the blacks were children and they can’t rule themselves. So the British thought it was okay to control and rule the natives with giving no rights to them. The natives had no right to vote in the British and they can just serve the invaders under their advanced weapons.Until the 18 centuries, the British stopped the slave trades and started to give a little bit of right to the Africans. They built railways and developed in Africa. They made connections between the rural areas and the urban areas. Communications were made between the outside world and Africa. Although developments appeared in Africa, all benefits owned by the British Empire and only very few were given to the natives. After the Second World War, lots of colonies’ controls were given back to the natives .Africans ruled their own lands, however, because of the natives didn’t have a chance to learn about the whole system of ruling a piece of land. That made a huge gap between the physical developments and the inside mind developments. Until now, most of the African countries still can’t get a well development on politics and economy. The British Empire did left developments on a very little amount of African countries. In general, the British left extreme negative impacts on Africa and also took away a lots from them.

Drug Behavior and Blood Brain Barrier Permeability Essay

Drug Behavior and Blood Brain Barrier Permeability - Essay Example Adolescent's innovation and curiosity can be transformed in dependence and addiction. Substance abuse is a maladaptive pattern leading to clinically significant impairment or distress. Several illicit substances produce dependence, defined as substance abuse that leads to loss of control, monopolization of time by substance use, and adverse medical, social, or emotional consequences that include tolerance and withdrawal (Gonzalez-Mayo, et al., 2005). There is a continued use in spite of knowing the problems that it causes. The mesolimbic dopamine system, particularly the nucleus accumbens, is a critical reinforcing site for drug addiction; this same pathway is believed to control drug craving and seeking behavior. It was recently proposed that addiction is a disease of learning and memory; classical conditioning describes learning in which a natural response is elicited by a conditioned, or learned, stimulus that previously was presented in conjunction with an unconditioned stimulus. Some evidence suggests that the mechanisms involved in the acute stimulant effects of cocaine and other illicit psychostimulants may be similar to the underlying features that explain chronic effects and addiction. The studies conducted in mice have allowed researchers to disclose important data regarding addiction pathways and neurotransmitter input. In humans, cocaine acute intoxication ca... On the other hand, ethanol intoxication causes disinhibition, emotional lability, slurred speech, ataxia, coma, and blackouts. Nicotine is one of the most addictive substances, and causes restlessness, insomnia, anxiety, and arrhythmias. Boudreau & Wolf (2005) define sensitization as "the augmentation of behavioral responses to drugs of abuse that occurs during their repeated administration and persists long after drug exposure is discontinued". The study conducted by Bainton, et al. is based on behavioral sensitization and the similarities between the addiction pathways of mammals and flies. By analyzing genetic features of Drosophila, the authors show that the behavioral defects observed in the mutant strains are not caused by accessibility changes of the administered drugs, but from alterations in the blood brain barrier, by means of changes in nervous system function. The Experimental Fly Since 1900, Drosophila flies have been used for genetic experiments. The fruit fly Drosophila melanogaster is highly accessible to genetic analyses, and has been introduced as a novel model organism to help interpret the complex foundation of drug-induced behaviors (Heberlein, 2008). In this study, flies were maintained on special agars and mutants where screened for drug sensitivity. First, researchers evaluated several fly strains that carried a mutation named EP1529, and found an increased sensitivity to both cocaine and nicotine exposures; excision of the mutation restored drug sensitivity in these flies. Additionally, the altered gene was identified as moody, which encode for a G protein-coupled receptor. In both larvae and adult flies,
