Analysis of a Corpus of Poetry :: Poems Writing Essays

Analysis of a Corpus of Poetry A corpus of 1000 lines of poetry (ten 100 line samples from ten different authors) is analyzed by a computerized connectionist model of poetic meter. The analysis finds that poets utilize measurably distinct patterns of stress and suggests that these patterns might "fingerprint" individual writers. In addition, the analysis shows that the variations of metrical patterns are in accord with the prevailing verse aesthetics of the period in which poets are writing. Introduction In English poetry, the single most compelling discriminator of that genre--that which defines a poem as a poem--has traditionally been its meter. Meter defines the length of the line, and thus the distinctive look of a poem on the page, and it sets, for the hearer of a poem, the telling regularity of a rhythm. Whether this rhythm also carries the burden of some of a poem's meaning or whether it is used only for a conventional aesthetic effect that invites the reader to take pleasure in its regularity or variations, meter is one of the central attributes of the genre of poetry. While the meter of a poem may or may not be strongly attended to by the poem's audience, or its critics, metrics has always been a matter of substantial concern for poets (see Addison [1994]). At each point in a line of poetry one factor in the decision favoring one word or syntactic pattern over another has been the metrical impact of that choice. Moreover, the limits of choice are not merely defined by a correctness rule such as the following: All stressed positions must have stressed syllables and no unstressed positions may have a stressed syllable. Metrical variations, resulting in what Halle and Keyser (1971), and others, have termed "metrical complexity" or "tension," are allowable and, in fact, produce much of the interest in a poem's rhythm. Traugott (1989), for example, speaking of Auden's poetry, notes that "a complex metrical design can . . . be identified that complements and enriches the multifarious verbal icons functioning at other levels of the langua ge" (294). In fact, poetic rhythm may only work when it destroys that very sense of design that it invokes; the extreme position is taken by Shklovsky (1917), who says, "the problem is not one of complicating the rhythm, but of disordering of the rhythm" (p.

Be My Brother

Belonging and alienation is the process of being either excluded or accepted by the society in which you live. Belong is a human conception,mostly considered a fundamental human need and a source of survival, safety, protection and happiness. To belong is usually considered positive and essential for a successful existence:however a negative sense of belonging:found among the displaced, marginalised and uncared for can lead to many social, filial and personal problems that can be almost insurmountable for the individual.The short trop fest film â€Å"Be My Brother† by Genevieve Clay 2009, represents these ideas through the films central characters. The film deals with society and people with disabilities feeling displaced within society due to prejudices. It also displays the notions of disconnection and isolation within the family home of the main character and his brother. The viewer here develops a strong connection to the idea of alienation and not belonging. The short fil m â€Å"Be My Brother† explores the concept of isolation through disabilities.Richard the protagonist is born with a disability and is isolated from society. Richard feels as though he doesn’t exist around his brother Damien. As the film progresses, Richard the protagonist meets a girl names Amanda and she neglects him at first, though she discovers another side to him, and so form a relationship with him. Social acceptance is the process of affiliation with society, but within the film â€Å"Be My Brother† it begins with the exclusion of the main character that has a disability. This is evident when Richard meets Amanda for the first time.As she see’s Richard approaching, she immediately moves towards the edge of the seat. The wide shot used in this scene indicates Amanda’s discomfort, where it demonstrates her fear towards people who are physically different. Furthermore, as Richard offers his hand to Amanda for a handshake, she quickly touches h is hand, and faces the other way. The close up shot within this scene reveals Amanda’s disgust towards Richard through hand gestures, where it emphasies her cruelty and superiority towards him.Clothing in this segment plays a crucial role. Amanda is wearing black clothing, which portrays her social standing, which represents class, elegance, and wealth, whereas Richard is wearing brown clothing, expressing dull, inferior and being less important. The full shot used demonstrates the relationships between characters, and where they stand in society. In addition, social acceptance can be displayed within the family. Richard feels displaced around his brother Damien.This is exemplified in the scene where Damien wearing a black hoodie with his hood up, incorporated with the wide shot depicts resentment and exclusion, where Damien feels embarrassed about his brother because he has a disability. The black hoodie symbolises something evil and depressed which contributes to the isolat ion Richard is experiencing. As Richard passes his hand with the audio recorder to Damien, Damien promptly tries to avoid Richard by moving his head. The close up shot allows the audience to see Damien’s facial expression conveying Damiens arrogance towards Richard.Social acceptance is the key concept within the film â€Å"Be My Brother†, where cameral angles and clothing play a crucial role in revealing the idea of feeling accepted and to belong within society. Disconnection and isolation is portrayed throughout the film between Richard and his brother. The negative sense of belonging, where someone feels isolated; found among the marginalised and uncared for can lead to anger and disappointment. The ideas of isolation can be seen at the beginning of the film. The extreme long shot at the beginning of the film reflects the setting, as Richard is disconnected from society.The blur of the background enhances Richards loneliness and societies prejudice against people wit h disabilities. Furthermore, the aspect of displacement can be manifested in the segment where Damien is sitting by himself at the bus stop and Richard is standing up, expressing his point. The major quote Richard plays in his audio recording â€Å"I am what I am, I can’t change that, my brother doesn’t seem to understand, he seems like he doesn’t want to be near me, I seem to always embarrass him and I don’t like to be ignored! shows evidence of self-expression where Richard seeks to be accepted by his brother and society. Anger and disappointment emerges within the audio recording which shows Richards frustration towards his brother, creating tension and indicating family breakdown.However, Damien experiences a change of heart when he is unable to pay his bus fare. Richard steps in and pays the driver. The long shot used in this scene culminates Damien’s feelings towards his brother, creating a journey as he walks down the narrow bus path toward s his brother and he is thinking and taking into account what his brother did for im and how he has treated his brother. The notions of anger, resentment and embarrassment slowly fade away as he takes off his hoodie and Richard hugs him. This important factor leads to acceptance with his brother and the formation of a positive family relationship. Disconnection and isolation is portrayed throughout the film between Richard and his brother, although it diminishes when Damien comes to the realisation that he is taking his brother for granted and thus the film shapes our understanding of belong and alienation.Ultimately the short film â€Å"Be My Brother† has further developed the understanding of belonging and alienation. Details of the social acceptance, disconnection and isolation portrayed throughout the film between Richard and his Brother, all expose â€Å"belonging and alienation† as a human conception whereby to belong is usually considered positive and to not bel ong leads to marginalisation. The feeling of belonging means acceptance however if someone is under the threat of not belonging the feelings of isolation, anger and disappointment emerge.

Comparison Of Depression In The Catcher In The Rye And The...

Compare and Contrast Depression; (n.) feelings of severe despondency and dejection; A mental health disorder characterized by persistently depressed mood or loss of interest in activities, causing significant impairment in daily life. Around 350 million individuals worldwide suffer from depression today; However, in the 1950s, depression was considered a rare condition. Today, doctors offer a wide variety of therapies and coping techniques for individuals but in the 1950s, electroshock therapy was the main procedure used on individuals. Among the â€Å"rare† cases were Sylvia Plath and J.D Salinger. Sylvia Plaths The Bell Jar and J.D. Salingers The Catcher in the Rye express two teenagers attempts to escape from repressive situations as†¦show more content†¦She is fascinated with the idea of death and different ways to die. Holden, however attempts to portray himself as an older man. He goes to bars and tries to get away with ordering alcohol, â€Å"I ordered a scotch and soda and told h im not to mix it- they lose their jobs if they get caught selling to a minor. I’m a goddamn minor.† (Chapter 10). Holden’s depression is subtle, but it affects him greatly. He hates being â€Å"young†, and abuses his privileges much too often, such as going to bars and ordering drinks. He even orders a prostitute later in the novel. Holden’s coping mechanism is different yes, but it works for him. While both Salinger and Plath portray themselves through Esther and Holden, their levels of expression differs greatly. Sylvia Plath expresses her own thoughts and wonders of death through Esther and while she is obviously depressed, Holden is more subtle, and reacts to situations differently. Although Holden and Esther are introverted, their outtake on life as well as their depression helps them go on to make astonishing discoveries about humanity. Both The Bell Jar and The Catcher in the Rye are set in New York City at some point throughout the novel. Ba sed on the knowledge of the location and the decade being the 1950s, we can assume that people are not the friendliest. Esther, having poor experience with men, once again comes to the harsh realization of men’s true desires, â€Å"I started to walk off.

This could perhaps be why Holden has such negative associations with growing older: all he sees ahead is death. Therefore, loss endured by both Holden and Esther leads to their eventual depression and isolation from society. Furthermore, depression and isolation of characters also stems from failure in the academic sector. Initially, Esther was making huge progress in terms of her talented writing skills and was offered a range of literary opportunities growing up
