A study of the songs and sonnets of John Donne as they show his reaction to the Elizabethan tradition

This study proposes to treat John Donne as a heretic of approach and idiom. It will show that his reaction against the Elizabethan traditions was sharp and complete. His approach to the theme of love in his Songs and Sonnets, circulated among his private friends, was radically different from the set, traditional treatment of love in the poetry of the late sixteenth and early seventeenth centuries. This latter type of poetry had lost all traces of originality and freshness; idiom, mood, and often form corresponded to a constant pattern which had become insipid. Set phrases, invocations, and approach had been used too frequently. The Elizabethans preferred the sonnet as a form of expression; and many of the poets composed a series of sonnets in which the theme was most often that of undying, unrequited love

The novels of Roddy Doyle

This dissertation is a critical examination of the five published novels of Roddy Doyle, The Commitments, The Snapper, The Van, Paddy Clarke Ha Ha Ha, and The Woman Who Walked into Doors. Since this dissertation will be the first of its kind about Doyle, its basic purpose will be to introduce the novels to the reading public and to convince the reading public that Doyle, although a very popular artist, is also a gifted writer who should be taken seriously. There are six chapters: an introduction and a chapter devoted to each novel. The introduction offers an overview of Doyle's works and a discussion of the qualities of his novels each subsequent chapter will examine. Each chapter discusses one of Doyle's novels by examining the following: his innovative use of language; his manipulation of his audience's reaction via humor and comedy; the role, however slight, of religion and politics; his overall social vision as projected in the novels both individually and as part of the complete body of work. The analysis also examines other prominent aspects of the individual novels, namely, the function of music in The Commitments; Sharon's character development in The Snapper, the grimness and despair of The Van; the use of double-writing in Paddy Clarke; and the way Paula's life may be seen as a metaphor for the abuses women suffer in a patriarchal society in The Woman. An extensive interview with Doyle, which he was gracious enough to grant me several months ago, is included as an appendix

A spectral analysis of the tones of five flutes constructed of different materials

The purpose of this investigation was to systematically analyze the tonal spectra of five modern Boehm-system flutes constructed of different materials, i.e., white gold, 14 karat gold, palladium, and sterling silver (2), and produced with the same specifications by a single manufacturer. The questions of concern in the study involved the influence of wall material, intensity level, frequency level, and the performer on the harmonic structure of tones produced on each flute used in the investigation. Two professional flutists played a sustained tone using no vibrato on three frequencies representing three registers of the flute range, i.e., 392 Hz, 784 Hz, and 1568 Hz. Each frequency investigated was played on each flute at two intensity levels corresponding to the forte and piano dynamic levels. Three trials were conducted for each frequency at a single intensity by each performer

Trajectories of Intimate Partner Violence Victimization

Introduction: The purposes of this study were to assess the extent to which latent trajectories of female intimate partner violence (IPV) victimization exist; and, if so, use negative childhood experiences to predict trajectory membership. Methods: We collected data from 1,575 women at 5 time-points regarding experiences during adolescence and their 4 years of college. We used latent class growth analysis to fit a series of person-centered, longitudinal models ranging from 1 to 5 trajectories. Once the best-fitting model was selected, we used negative childhood experience variables—sexual abuse, physical abuse, and witnessing domestic violence—to predict most-likely trajectory membership via multinomial logistic regression. Results: A 5-trajectory model best fit the data both statistically and in terms of interpretability. The trajectories across time were interpreted as low or no IPV, low to moderate IPV, moderate to low IPV, high to moderate IPV, and high and increasing IPV, respectively. Negative childhood experiences differentiated trajectory membership, somewhat, with childhood sexual abuse as a consistent predictor of membership in elevated IPV trajectories. Conclusion: Our analyses show how IPV risk changes over time and in different ways. These differential patterns of IPV suggest the need for prevention strategies tailored for women that consider victimization experiences in childhood and early adulthood

Predictors of premilitary courtship violence in a Navy recruit sample

Research on intimate partner (IP) aggression was extended to premilitary experiences of IP violence among U.S. Navy recruits. Riggs and O'Leary's (1989) model of courtship aggression was examined separately for men (N = 1,307) and women (N = 1,477). A test was conducted of the model using participant gender along with the significant variables from the initial analyses and the interaction of gender with each of these variables. Situational components explained more variance that did the background components. For women and men, the amount of variance accounted for was almost tripled after the addition of the situational factors. Partner aggression contributed to a substantial increase in the amount of variance. Partner's verbal aggression was the single best predictor of aggression, and partner's physical aggression was the second-best predictor. The situational component substantially increased the predictive power of the model. The results support the validity of the Riggs and O'Leary model

Rates of DSM-IV-TR trauma exposure and posttraumatic stress disorder among newly matriculated college students

The negotiation of the freedoms and responsibilities introduced as adolescents begin college may be particularly challenging for those with a trauma history and traumatic stress sequelae (posttraumatic stress disorder; PTSD). The present study examined the prevalence of and risk for trauma and PTSD in a large sample of college students. Matriculating students (N _ 3,014; 1,763 female, 1,251 male) at two U.S. universities completed online and paper assessments. Sixty-six percent reported exposure to a Criterion A trauma. Nine percent met criteria for PTSD. Female gender was a risk factor for trauma exposure. Gender and socioeconomic status (SES) were associated with trauma severity. Although in bivariate models, gender and SES were associated with PTSD, multivariate analyses suggested this risk was a function of trauma severity. Thus, students enter college with significant trauma histories and PTSD symptoms. Findings highlight the potential for outreach to incoming students with trauma and point to research directions to enhance understanding of the psychological needs of entering college students

Trajectories of Male Sexual Aggression from Adolescence through College: A Latent Class Growth Analysis

Approximately 25% of male college students report engaging in some form of sexual coercion by the end of their fourth year of college. White and Smith (2004) found that negative childhood experiences—childhood sexual abuse, childhood physical abuse, and witnessing domestic violence—predicted sexual aggression perpetrated before college, but not during the subsequent college years, a puzzling finding in view of the reasonably consistent rates of sexual aggression from adolescence to the first 2 years of college. The current study takes a person-centered approach to sexual aggression in an attempt to resolve this discrepancy. We examined the possibility of cohesive subgroups of men in terms of their frequency of sexual aggression across the pre-college and college years. A series of latent class growth models were fit to an existing longitudinal dataset of sexual experiences collected across four time points—pre-college through year 3 of college. A four-trajectory model fit the data well, exhibiting significantly better fit than a three-trajectory model. The four trajectories are interpreted as men who perpetrate sexual aggression at (1) low (71.5% of the sample), (2) moderate (21.2%), (3) decreasing (4.2%), and (4) increasing (3.1%) frequencies across time. Negative childhood experiences predicted membership of the decreasing trajectory, relative to the low trajectory, but did not predict membership of the increasing trajectory, explaining the discrepancy uncovered by White and Smith. Implications for primary prevention of sexual aggression are discussed

Victim Voice in Re-Envisioning Responses to Sexual and Physical Violence Nationally and Internationally

Internationally and in the United States many victims of sexual assault and domestic violence are unserved, underserved, or ill-served, especially those from the most vulnerable populations. Programs developed in the United States are routinely exported to developing countries but often without success. Notably, the failures seen internationally resemble those in the United States and are related to structural and attitudinal–cultural factors. Many victims do not disclose, and if they do seek services, they often report that available options mismatch their objectives, present accessibility challenges, disempower their pursuit of justice, and fail to augment needed resources. A deeper understanding of obstacles to effective service provision is needed if the United States is to continue to be an international partner in victim response and violence prevention. This article builds on what is known about service delivery challenges in U.S. programs to envision a path forward that concomitantly accommodates anticipation of shrinking resources, by (a) reviewing illustrative services and feedback from victims about utilizing them; (b) examining structural inequalities and the intersections of personal and contextual features that both increase vulnerability to victimization and decrease accessibility and acceptability of services; (c) advocating for reintroduction of direct victim voice into response planning to enhance reach and relevance; and (d) reorienting delivery systems, community partnerships, and Coordinated Community Response teams. The authors suggest as the way forward pairing direct victim voice with open-minded listening to expressed priorities, especially in vulnerable populations, and designing services accordingly. Through a process that prioritizes adaptation to diverse needs and cultures, U.S models can increase desirability, equity, and thrift at home as well as enhance international relevance

Earth landscapes

In mountains I see a soft beauty and sensuality. These things I see especially in old mountains, gentled by the ravages of nature, smoothed over and worn down. From far away, the trees and other vegetation seem like a soft blanket covering them. There are similarities in the basic forms, repeated over and over again. Yet each mountain or hill is, by virtue of its own details and the way it joins the next one, unique. Junctions of swells with valleys result in a rythmic sensuality of form. This rythmic sensuality is complemented by the Individual characteristics in each segment of the landscape. Colors are harmonious, earthy, and warm in nature. Even the brightness of Fall leaf color is subdued from a distance, by its commingling with other colors rear it. To choose to represent the landscape completely and perfectly would be natural. However, a personal interpretation is necessary. I feel the need to intensify the particular aspects of the mountains as I see them: to accentuate the soft undulating forms and the warm sensual colors. My mountains suggest actual representations of real mountains but are also meant to portray my psychological feelings about them
