The Workings Of The Endocrine System - 1183 Words

Introduction: Within field studies, the best way to understand the workings of the endocrine system usually involves injecting a specimen with a hormone or removing the gonads of the specimen to observe changes in hormone concentrations (Mazur, Booth, Dabbs, 1992). However with human subjects this kind of procedure proves to be rather unethical, and therefore researchers have found that the best way to observe a particular hormone, such as testosterone, is to observe what occurs when an individual is subjected to competition (Mazur et al., 1992). It has been observed that as an individual, male or female, participates in a competitive event, their testosterone levels are subject to rise (Booth, Shelley, Mazur, Tharp, Kittok, 1989). This notion is further supported through the observation of rising testosterone levels in those individuals who win their event. In fact it has been suggested that an individual’s testosterone level increases in order to maintain an aura of domina nce, and thus the act of winning a competition increases the level of testosterone in order to maintain that dominance and level of competitiveness over the game (Booth et al., 1989). While testosterone levels increase with victory, defeat often inspires the decrease of testosterone levels as well as feelings of competitiveness (Booth et al., 1989). This phenomenon is not limited to just those individuals competing in an event; in fact it has also been observed that even those watching a particularShow MoreRelatedThe Endocrine System Is Made Up Of Cells And Glands That1137 Words   |  5 Pages The endocrine system is made up of cells and glands that make hormones and release them into the blood.

Comparing Virginia Woolfs Mrs. Dalloway and Emily...

Comparing Virginia Woolfs Mrs. Dalloway and Emily Brontes Wuthering Heights Virginia Woolf’s Mrs. Dalloway and Emily Bronte’s Wuthering Heights share similarities in many aspects, perhaps most plainly seen in the plots: just as Clarissa marries Richard rather than Peter Walsh in order to secure a comfortable life for herself, Catherine chooses Edgar Linton over Heathcliff in an attempt to wrest both herself and Heathcliff from the squalid lifestyle of Wuthering Heights. However, these two novels also overlap in thematic elements in that both are concerned with the opposing forces of civilization or order and chaos or madness. The recurring image of the house is an important symbol used to illustrate both authors’ order versus chaos†¦show more content†¦The first instance of window imagery is deceivingly small and easy to pass over, but upon reflection it creates a certain symmetry by subtly foreshadowing the final window scene. In the very opening section of the book, Clarissa’s departure from the house dredges up memorie s of her time at Bourton, of scenes with Peter Walsh that took place in front of an open window. This memory, brought about by the impact of the early morning air, also reminds her of the â€Å"solemn† feeling this incident gave her â€Å"standing there at the open window, that something awful was about to happen.† Though fleeting and lightly discussed, this emotion placed so close to the beginning of the novel seems to indicate the dangerous nature of an open window, which anticipates both Septimus’ death and Clarissa’s later musings in front of a window. Another small but important window scene takes place after Clarissa returns home to discover that her husband has been invited to Millicent Bruton’s lunch party but she has not. After reading the message about the party on a notepad, she begins to retreat upstairs to her private room, â€Å"a single figure against the appalling night.† As she lingers before the â€Å"open staircase window,† she feels her own aging, â€Å"suddenly shriveled, aged, breastless†¦ out of doors, out of the window, out of her body and brain which now failed†¦Ã¢â‚¬  Again, there is a hint of danger as death is portrayed as a somewhat alluring transcendental experience,

Comparing Branagh and Olivier Free Essays

The two movie versions of Shakespeare’s Hamlet that are directed by Laurence Olivier and Kenneth Branagh have similarities and differences. The similarities include how Hamlet feels betrayed by his mother because of her sudden marriage after the death of his father. The differences include how Hamlet is portrayed as a character. We will write a custom essay sample on Comparing Branagh and Olivier or any similar topic only for you Order Now Olivier uses the Hamlet’s relationship with Gertrude and his soliloquy to portray Hamlet as confused, whereas Branagh uses the same dynamics to portray Hamlet as furious. Olivier presents Hamlet’s relationship with Gertrude as more physical in order to ndicate Hamlet’s confusion, while Branagh presents the relationship between Hamlet and his mother as less physical to reinforce his feelings of frustration. During the scene where Claudius and Gertrude are encouraging Hamlet to stay in Denmark, Gertrude freely touches Hamlet and kisses him on the mouth to console her grieving son (Olivier, 1948). During this scene, Hamlet is sitting at the edge of the table wearing all black and is turned away from everyone. He is upset that his mother has remarried such a short time after his father’s death. His tone of voice suggests that e is full of grief, devastated about the death of his father, and feeling betrayed by his mother. Even though he feels betrayed, Hamlet passively allows his mother to embrace and kiss him. Hamlet is confused, and has no sense of how to deal with his conflicting feelings. Branagh, however, presents the relationship between Hamlet and his mother without any physical contact between the two. During the same scene in Branagh’s version, the queen smiles and encourages Hamlet to stay instead of returning to Wittenberg (Branagh, 1996). In comparison to Olivier’s Hamlet, Branagh’s Hamlet has a different tone of voice. His tone of voice is on the edge of tears. When Gertrude consoles Hamlet and urges him to stay in Denmark, he agrees to stay, but does not engage in any physical contact with his mother. He remains distant from his mother, both emotionally and physically. Unlike Olivier’s Hamlet, Branagh’s Hamlet shows that he is more bitter than Olivier’s Hamlet about Gertrude’s quick marriage. Thus, the directors’ depictions of Hamlet’s interaction with Gertrude in the two films reveal differing interpretations of Hamlet’s response to feeling betrayed. The two film versions also use Hamlet’s first soliloquy to depict their different interpretations of Hamlet’s character. Olivier’s Hamlet delivers his soliloquy in his thoughts to indicate his confusion, whereas Branagh’s Hamlet delivers his soliloquy in spoken words to show his frustration after he learns that his mother has married Claudius. In the Olivier version of the play, Hamlet’s first soliloquy is spoken in his head (Olivier, 1948). In this speech, he emphasizes that only a little amount of time has passed after his father’s death and that Gertrude has remarried too quickly. He also emphasizes his confusion about Gertrude’s marriage to Claudius, when Gertrude used to follow his father like Niobe. In Olivier’s version of the soliloquy, Hamlet is grieving over his father’s death, but he is more upset about his mother’s quick marriage to Claudius, his tamer’s brother. During his soliloquy, Hamlet says â€Å"trail thy name is woman† (Olivier, 1948) calling his mother weak-hearted for remarrying too quickly. In contrast to Olivier’s Hamlet, Branagh’s Hamlet speaks and yells to emphasize points in his soliloquy. He speaks of the same issues, but the tone of voice s different. He sounds exhausted, annoyed, and speaks as if he is about to start crying. However, when he mentions the point that frustrates him the most, his voice becomes significantly louder; when he yells â€Å"yet within a month! † (Branagh, 1996), emphasizing the short amount of time between the death and marriage, he reveals his bitterness. He feels betrayed and angry at the way Gertrude has moved on so quickly, rather than confused and sad, as he does in Olivier’s film. Thus, although both Olivier’s and Branagh’s versions of Hamlet stress the same conflict about his other, Hamlet is characterized differently in each film. In both film versions of Hamlet, the protagonist faces the same conflict, but Olivier and Branagh take different approaches to portraying Hamlet. In Olivier’s version, Hamlet’s relationship with Gertrude is portrayed in a physical manner to stress Hamlet’s passivity and feeling of confusion, whereas in Branagh’s depiction, Hamlet’s relationship with Gertrude reveals a less physical and more distant relationship in order to indicate his anger and frustration. Their soliloquies also distinguish the directors’ two different ersions of Hamlet; Olivier’s Hamlet delivers his speech in his thoughts, adopting a passive style to suggest Hamlet’s confusion, while Branagh’s Hamlet delivers his speech out loud to indicate his anger and frustration. These two different depictions of the main character reveal how critical the director’s input is in creating a distinct interpretation of Shakespeare’s plays.

The Slave Trade free essay sample

Why was the slave trade abolished? The slave trade had high social costs. It was a process of transporting and selling Africans to the other countries to become slaves. Usually, the Africans would be transported by the Europeans and they would be sent to North America where most plantation owners who needed slaves were. They would get sold and become slaves and work for long hours on the plantations. However, in 1808, the slave trade came to an end and it tidinesss end without help.There were 3 main factors that supported the end of slave trade, the abolitionists, the slaves themselves and the economic factors. Among the 3 factors, one of them was the abolitionists. The abolitionists contributed a lot and in fact would say that it was probably the most important factor. Out of all the abolitionists, there were 2 that were particularly passionate about helping to end the slave trade. One Of them was called Thomas Clarion, who was a British man and worked for 71 years trying to stop slavery. As source D shows, Thomas Clarion always carried around a box of objects such as chains and thumb screws that he used to demonstrate to people what slavery was like so that people would get a better picture of slavery. Source A shows the type of speech that Thomas Clarion would have made, this line has been taken from source A to show that Thomas Clarion was very determined to put an end to the slave trade: There are some of the evils which you are called upon this night to an end to. Another abolitionist that contributed a lot was William Wildflower.Wildflower was highly responsible for the slave trade and he was actually influenced by an ex slave, John Newton. After a number of attempts of trying to bring the private Bills before parliament, he did not succeed but he never gave up. Eventually, he succeeded on the 25th March 1807 but he still didnt completely abolish the slave trade. Whilst he was laying on his deathbed on the 26th July 1833, he was told that slavery abolition bill was passed by Parliament and freedom was then granted to all the slaves within the British Empire.This is an example of an extract taken from a speech that Wildflower would make: When consider the magnitude of the subject which am to bring before the House-?a subject, in which the interests, not of this country, nor of Europe alone, but of the whole world, and of posterity, are involved: ND when I think, at the same time, on the weakness of the advocate who has undertaken this great cause-?when these reflections press upon my mind, it is impossible for me not to feel both terrified and concerned at my own inadequacy to such a task. Source E shows William Wildflower introducing the law to ban slave trade in the British Empire. Lots of other abolitionists also helped to ban the slave t rade such as Hannah More who was a writer and in 1 788, she wrote Slavery, a poem to coincide with Wildernesss parliamentary campaign. In addition, not only did the abolitionists do the work but the slaves also had o fight back for themselves. Evidence shows that many slaves have fought back and have succeeded just like what source B shows. Source B shows the rebellion that the slaves made during the Haitian revolution in 1 791. By 1 803, they succeeded and not only did they end slavery but also the French control over the colony. Furthermore, source G suggests that black people can be as powerful as white people. Throughout history Toasting Liverwurst has been the greatest slave revolt and he has successfully defeated both the British and French armies. Source H is an extract that has been used to describeToasting Liverwurst by The London gazette: According to all accounts he is a negro born to vindicate the claims of this species and to show that character of men is independent of the color of their skin. This reveals that the white people are starting to see what the black people can do. Moreover, Aloud Equation who was previously a slave published his book The Interesting Narrative of the Life of Aloud Equation which sold over 2 million copies and the book was what really made the publics eyes open. They saw things from the point Of view of a person who was a slave before.The final reason why the slave trade came to end was because of the economic factors. Source I could be the evidence to suggest why the slave trade came to an end: In 1771, 2728 slaves were imported, but in 1 772, no slaves were imported anymore. This was because Cuba and Brazil started to produce cheaper sugar, and at the end this person quoted if Britain could buy sugar somewhere else for less money it would. Without the profits of sugar, plantation owners would have to shut the plantations down as the profits helped them to afford a huge plantation house, as source F shows.Source C, a book review by David Richardson on the book The Sugar Industry and the Abolition of The Slave Trade also reveals that the costs of sugar were rising: British West Indian Slavery.. . Had run its course by the end of the eighteenth century, squeezed between rising costs of producing and marketing sugar. In conclusion, think that the most important reason why the slave trade came to an end is the abolitionist because the power is in the parliaments hands and if the abolitionists didnt make speeches to try and convince the public, slave trade probably wouldnt have been banned so early.I also consider the slaves power to be quite an important aspect because if they hadnt of fought back and was really determined to go home then no one would of knew that they didnt like it and so no one would think of their feelings. Chose economic factors to be the least important reason because if Cuba and Brazil never produced any sugar that was cheaper than Britain then would the slave trade of ended? No one can really control the economy! Overall, I think that the slave trade came to an end because both the white and black people took action.
