The Effects Of Sleep Deprivation On Memory - 1055 Words

Sleep is essential for optimal human function. In fact, a lack of sleep can actually affect important cognitive functions, like memory. A 2007 study added to the already substantial evidence that even acute total sleep deprivation impairs attentiveness, working memory, and reaction time in various tasks (Alhola, Polo-Kantola). One such way to further this investigation of the effects of sleep deprivation on memory is through the Memory Interference Test, or MIT. MIT is a program designed by Gaston Pfluegl, Ph.D., and Enrique Lopez, Psy. D., at UCLA to test the memory of students. Along with a memory test, the MIT also anonymously collected the physical states, mental states, and demographics of each student test subject, providing a substantial database through which students can test hypotheses, such as the connection between sleep deprivation and memory. Since the MIT requires short-term memory recall, the hours of sleep a student had before taking the test could have a noticeable effect on his or her performance. An unprecedented study this year found that sleep deprivation may actually even induce false memories, which would certainly impact a student taking the MIT because the test requires the subject to recognize images that have been previously presented to them (Frenda, et al). The hypothesis is that students who slept 8 hours before the test will perform better on the MIT than students who only slept 4 hours. The null hypothesis is that students who had adequateShow MoreRelatedThe Effects Of Sleep Deprivation On Memory1605 Words   |  7 Pagesstudy investigated the effects of sleep deprivation on memory.

Cause And Impact Of The Cold War Essay - 1556 Words

What was the Cold War and what impact did it have globally during the 20th century? To understand the Cold War and the many sides that there were to it, you must understand how the world got to that point. Many contributing factors led to this conflict and existed during this time. The purpose of this paper is to examine the cause and effect that this â€Å"war† had on the planet and its effect is holds on history, even to this day. The Cold War is defined as â€Å"a conflict over ideological differences carried on by methods short of sustained overt military action and usually without breaking off diplomatic relations† (Merriam-Webster, 2017). During World War II, the United States and the Soviet Union had a united goal; to defeat the Axis powers†¦show more content†¦(Staff, 2009) This â€Å"Cold War†, which was first termed by George Orwell in an article published in 1945, then later used in a speech at the State House by presidential advisor Bernard Baruch in South Carolina in 1947 had begun to solidify in 1947-1948. Caused by aid provided under the Marshall Plan, which was designed to help Europe rebuild after the war, the Soviets began to see American influence in all of Europe. (Editors, 2017). Also, in 1947, President Truman delivered a speech known as the â€Å"Truman Doctrine†. This speech embraced the containment of Soviet communism as the foundation of American foreign policies. In his speech, he gave an example of how Greece had requested assistance from the United States, as their army was small and ill-equipped to handle with the larger Soviet occupied northern borders. The encroaching Soviet territories of Albania, Bulgaria and Yugoslavia were violating border agreements which the Greeks were unable to compete with. President Truma n used this to drive home his point of the dangers that were immediate with the Soviet Union. (Foner, 2014, p. 214) In 1948, the Soviet Union tried to blockade the Western-held sectors of West Berlin.

Besides of our normal eeting in college, the discussions also were held through the MSN chat and email.

In order to get more facts about the company, we held an interview with one of their sales representatives on 2nd November 2009. From the 1 hour interview, we managed to gather the information needed for this project, which for example are, their current marketing strategies and the companys internal issues. One important lesson I learnt from the interview is that, even though small firms is not properly structured, it does not mean that SMEs do not engage in marketing. It is only that, they are doing marketing according to their own terms and not according to a theoretical framework. Other than interviewing the sales representatives, my group and I also did a research based from their websites and also by reading books. It is important so that e will have a broader view on the business environment and help us to write the task more accurately. In order to complete the task, I read Marketing and Entrepreneurship in SMEs, Principles of Marketing by Philip Kotler and Fundamentals of Management to have a better understanding about SME and its management as well as several websites related to the topic which for example SME Info Portal. This whole process, I believe has improved both my knowledge and skills. I learnt how to work with others as a team, it taught me how to compromise as I need to be open in accepting other people ideas or opinion and also in handling conflicts. In addition to that, basically, I am more knowledgeable on this topic. From the research, I discovered various type of SME in Malaysia which can classified under 3 category that are Primary Agriculture, Manufacturing (including Agro-Based) MRS, Services Sector (including CT) . Furthermore, I am also more aware on characteristics needed to be an entrepreneur, and one essential trait they must have is to be a risk taker. This is important as SME business environment is very uncertain and whenever they make a wrong decision, it may affect their business as a whole. Reflective Statement free essay sample He was of medium height. His shapely, slim figure and broad shoulders gave evidence of a strong constitution, capable of enduring all the hardships of a nomad life and changes of climates, and of resisting with success both the demoralizing effects of life in the Capital and tempests of the soul† (Lermontov pg. 50). A true man is a man who takes responsibility. He is a man who takes responsibility for himself, his family, his influence, his actions, and his accountability. What do you think defines a true man? If a man takes responsibility for what he does, what he is, and who he is he would not have to blame the society, his surroundings, and other people he has met or known. But I cannot define a man in only my perspective because there are many definitions to what a man is, and what he symbolizes. Of course there isn’t only one type of man in this world, but I will explain my understanding of a man I’ve learned about. We will write a custom essay sample on Reflective Statement or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In the novel, A Hero of Our Time, Mikhail Lermontov uses the Byronic influence to create the characterization of Pechorin, who is also known as Grigori Alexandrovich. To give you a little knowledge of what the Byronic influence is, I will tell you some information about it. The Byronic influence happened in the 1700s, and it happened due to Lord Byron’s works, such as his poems. Lord Byron’s influence was known throughout the whole world by many people, including Russian Romantic writer, poet, and painter, Mikahil Lermontov. Through our interactive orals (IOs), the topic Byronic Influence stood out the most because I felt that it would play a big part within the novel, A Hero of Our Time. As I thought, it did play a big part in the novel. Lermontov’s character, Pechorin is characterized as the â€Å"Byronic hero†. A Byronic hero is defined as a melancholy and rebellious young man, distressed by a terrible wrong he committed in the past. In the novel, Pechorin is a very intriguing person. He makes it confusing for us to understand his situation, but yet he makes us pity him at the same time. Pechorin is known for his embodiment of the Byronic hero. Byron’s works were international, meaning they were known worldwide to everyone. Lermontov mentions his name several times throughout the novel. According to the Byronic hero and influence, Pechorin is a character of contradiction. He is both sensitive and cynical. He is possessed of extreme arrogance, yet has a deep insight into his own character and resembles the melancholy of the romantic hero who broods on the futility of existence and the certainty of death. Pechorin’s whole philosophy concerning existence is oriented towards the nihilistic, creating in him somewhat of a distanced, alienated personality. Lermontov’s characterization of Pechorin is the reason to why we as the audience pity him in many ways. But, Pechorins behavior as a character soon changes after Bela, the young lady who he kidnapped at first gets kidnapped by his enemy, Kazbich, and becomes mortally wounded. After 2 days of suffering, Bela spoke of her inner fears and her feelings for Pechorin, who listened without once leaving her side. After her death, Pechorin became physically ill, lost some weight and became very unsociable. After meeting with Maxim, who is similar to a close friend, again, he acts coldly and antisocial, showing deep depression and disinterest in interaction. He soon dies on his way back from Persia, admitting to Maxim before that he is sure he will never return. Pechorin described his own personality as self-destructive, admitting he himself doesnt understand his purpose in the world of men. His boredom with life, feeling of emptiness, forces him to indulge in all possible pleasures and experiences, which soon, cause the downfall of those closest to him. He starts to realize this with Vera and Grushnitsky, while the tragedy with Bela soon leads to his complete emotional collapse. Pechorin treats women as a reason for endless conquests and does not consider them worthy of any particular respect. He considers women such as Princess Mary to be little more than pawns in his games of romantic issues, which in effect hold no meaning in his pleasure. This is shown in his comment on Princess Mary: â€Å"I often wonder why I’m trying so hard to win the love of a girl I have no desire to seduce and whom I’d never marry. † I believe that Pechorin thinks this way due to the fact that he’s been hurt by his first love, Vera. Vera and Pechorin were deeply in love until she left him because of money issues. From then on, he lost his trust in women. He still had interest in women, but he would not trust them to the point where he would marry them. Lermontov brings to life and is able to define the Byronic hero by describing him from different angles and framing him with other characters. The reader comes to understand that the hero is a complex entity: his morality is misguided, his motives are inconsistent, he is isolated and he suffers deeply while struggling to understand himself. Though the entire novel is devoted to developing Pechorin as a complex character A Hero of Our Time is critical of the Byronic hero and reveals the heros hypocrisy, indulgence in melodrama, and self-pity. Grushnitsky is maneuvered to expose these qualities in Pechorin as well as define some other aspects of the Byronic hero. Because Byronic tendencies had become fashionable to imitate, Lermontov was able to define the hero by defining the impostor. In this way, Lermontov created a background on which the heros qualities would become readily detectable. Whether he is being criticized or defined, it is clear that the Byronic hero is under scrutiny in A Hero of our Time. Through Pechorins journal and accounts by other characters, the reader becomes aware of Pechorins flaws, his hypocrisy, and his pretension. Simultaneously though, the reader is educated to the real qualities of the Hero; his superiority and his suffering. Grushnitsky is used to outline some of the more tangible requirements of heroic status while in some cases serving as a backdrop for irony. With these devices Lermontov exposes the hero from all angles and Pechorin takes on the complexities of the Byronic hero.
