    Abstract:

    This dissertation explored the relationship of ethnic matching between abusive and/or neglectful ethnic minority parents and minority counselors. Specifically, it examined these clients' satisfaction with and engagement in counseling as well as type of termination (unilateral or continuing) and outcome (client adjustment, meeting of agency goals, and re-abuse). This study also looked at the relationships of ethnic identity and acculturation discrepancies of clients who abused their children and their counselors, who were either ethnically matched or not matched, to client satisfaction, client engagement, client termination type, and client outcome. This dissertation sought to answer the following questions: (a) Are child-abusing clients who are ethnically matched with their counselors more satisfied with the intake counseling session than those who are not ethnically matched? (b) Are child-abusing clients who are ethnically matched with counselors more likely to become engaged in counseling than their non-matched counterparts? (c) Are child-abusing clients who are ethnically matched with their counselors less likely to terminate early than those who are not ethnically matched? ( d) Do child-abusing clients who are ethnically matched with their counselors have better outcomes than those who are not ethnically matched? (e) How do client-counselor differences in ethnic identity and acculturation relate to client satisfaction, engagement, termination, and outcome? I confirmed that abusive/neglectful clients who were ethnically matched with their counselors were significantly less likely to terminate prematurely after engagement than ethnically unmatched clients. Ethnic matching was not related to engagement, client satisfaction, or counseling outcome. Overall, results of this study suggested that ethnic matching per se may have little to do with client satisfaction, engagement, and outcome. Results also suggested that in contrast to ethnic matching, client-counselor ethnic identity discrepancy is important in client engagement, early-termination, and counseling outcome regardless of whether or not clients are ethnically matched. Although acculturation discrepancy was related to re-abuse, it had little relationship with the other variables in this study.

    Abstract:

    We examined whether valence or arousal levels affect decision and movement times in Parkinson's disease (PD) and in healthy aging. For both decision and movement time, we were interested in differences in the speed and variability in responding. We also studied whether emotional experience is altered as a result of the aging process and PD pathology. Participants included 16 young healthy adults, 15 older healthy adults, and 15 non-demented individuals with mild PD. The PD participants were tested on medication. Participants viewed pictures from the International Affective Picture System (IAPS; Lang, Bradley, & Cuthbert, 2001) differing in emotional content and performed self-report valence and arousal ratings during picture presentation. Components of reaction time (i.e., decision time [DT] and movement time [MT]) were assessed during a forced-choice reaction time task. Results demonstrated that DT and MT were differentially affected by emotional stimuli. The PD group demonstrated significantly longer and more variable DTs than did the healthy controls for negative, positive, and neutral pictures; however, only the MTs for negative and neutral images were significantly different or more variable between groups. Although DTs were longer for the older control group relative to the younger control group, MTs were equivalent between the two control groups. Evidence of altered emotional experience in PD was found, as the PD participants rated negative pictures as less negative than did healthy older adults; however, this significant difference was reduced to a trend when individuals with more severe depressive symptomatology were excluded from the analysis. In addition, high arousal images were rated as more highly arousing among the PD group when depressed individuals were not included in the analyses. There was no evidence of impaired emotional experience as a function of aging, as valence and arousal ratings were not significantly different between younger and older adults. Better understanding of emotional processing deficits, which have been associated with poorer quality of life, in healthy aging and PD may lead to a better understanding of the neural bases of emotional processing, as well as offer treatment approaches.

  • PRICING COLLATERALIZED DEBT OBLIGATIONS WITH PURE JUMP LÉVY PROCESSES: A DYNAMIC BOTTOM-UP APPROACH

    Abstract:

    The Gaussian copula model is the industry standard in pricing CDO tranches because of its easy implementation and speedy calibration. However, it has several well-known shortcomings: It leads to the so-called correlation smile", generates symmetric and light-tailed asset return distributions and it is static. This dissertation proposes a dynamic bottom-up model based on a pure jump Lévy process, a path rarely taken in the credit pricing literature, and makes a comprehensive empirical analysis of bottom-up CDO pricing models. Owing to its ability to capture asymmetric heavy-tailed return distributions and to accommodate different degrees of dampening for positive and negative jumps, empirical evidence shows that the proposed model significantly outperforms the models commonly employed in the industry and frequently referenced in the literature in fitting CDX and iTraxx tranche spreads. As such, it constitutes an important addition to the credit pricing literature.

    Abstract:

    The Powerful Voice of Women Dramatists in the Arab American Theatre Movement by Dalia Basiouny Advisor: Marvin Carlson This dissertation traces the recent emergance of the Arab American Theatre movement, focusing on plays by women dramatists. It presents an overview of contemporary theatre and performances by Arab American women, and explores their focus on political theatre and identity politics, through an examination of works by fifteen contemporary women playwrights and performers. The emergance of this relatively large group of women theatre writers of Arab descent is a significant cultural phenomenon because their productions not only help to create and solidify an Arab American identity for themselves, they also offer this constructed identity to their audiences. The political expression of this young theatre movement takes on different articulations, according to the different genres the dramatists use. The introduction presents Rania Khalil's silent performance piece and Suheir Hammad's collage performance . Chapter one examines three autobiographical solo performances. Leila Buck's ISite and Nora Armani's are theatrical presentations of the self through writing the story of lineage. Soha Al Jurf's documents her visits to the land of origin in the Arab world, connecting her search for identity to the killing of her Palestinian aunt. Chapter two explores the expansion from the individual search to the community. Heather Raffo's is based on interviews conducted over a period of ten years with Iraqi women inside Iraq and in exile, while Nibras Group's presents verbatim responses to the question "What is Arab?" based on fifty interviews with Arab Americans and other Americans. Chapter three discusses how plays by Arab American women dramatists deal with the negotiation of identity by second-generation Arabs in America, looking at two plays by Betty Shamieh, and , and Laura Shamas' . Chapter four examines the comedy of Arab Americans, looking at the work of Maysoon Zayid and discussing the short plays presented at the Arab American Comedy Festival. The conclusion looks at the dominance of women's voice in this emerging theatre movement, and explores the aesthetic of this Arab American theatre.

    Abstract:

    In this dissertation, we consider some non-classical methods in epistemic logic and games. We first consider, dynamic epistemic logics in topological and geometric semantics, and then extend such ideas to the cases where inconsistencies are allowed. Then, as a case example, we discuss a well known paradox in game theory which is essentially a two-person Russell's paradox. Finally, we conclude with considering an alternative approach to games where strategies are considered as the primitives of the theory, and advancing some results.

    Abstract:

    According to the forecast of the US Census Bureau, Latinos are the largest, fastest-growing ethnic group within the United States today and will comprise the majority of the US labor force sometime during the mid-21st century. Yet today, the youth of this diverse segment of the population are plagued by alarmingly high high school dropout rates, about double that of African-Americans youth and triple that of white youth. This yawning disparity prompts the examination of the social conditions contributing to this social crisis. How do demographic, aspirational, school-level, and socioeconomic variables affect the decision that so many Latino youth make to drop out of high school? Employing three waves from the Educational Longitudinal Study (2002, 2004 & 2006), this study seeks to add to the discussion of the causes of dropping out among Latinos by examining factors that influence high school persistence rates for a nationally representative sample of Latino youth. This dissertation's theoretical framework combines Bourdieu and Passeron's theory of societal reproduction, labeling theory, and social motivation theory. Variables from all three levels exerted some influence on dropout patterns among Latino youth. Attending a high school located in an urban center was especially significant in predicting the likelihood that a Latino in our sample would drop out of high school, despite the well-known personal costs.

    Abstract:

    One variable frequently found positively associated with relationship satisfaction is sexual satisfaction. In turn, relationship satisfaction is positively associated with both reduced individual stress of each partner and with subjective quality of life. However, little research has examined the relationship among all of these variables. This study examined the possible gender differences in the associations among relationship satisfaction, sexual satisfaction, individual stress, and quality of life. Additionally, this study explored whether the frequency of sex impacts the association among relationship satisfaction and well-being (individual stress and quality of life) for men, but not for women. There were some gender differences in the findings. Specifically, results showed that for men, sexual satisfaction and sexual conflicts were associated with their relationship satisfaction, stress, and quality of life. However, for women, sexual satisfaction and sexual conflicts were not associated with their relationship satisfaction, stress, and quality of life. The results also demonstrated that for both men and women, sexual frequency was not associated with their relationship satisfaction, quality of life, and stress.

  • Neverending Stories: Unauthorized Continuations, Fictional Realities, and the Long-Form Narrative from 1590 - 2011

    Abstract:

    In reader-response theory, the open text demands that its readers collaborate in its construction. Such participation requires that these readers invest in the text's narrative universe, an investment made more possible when a fiction exhibits the properties of selvage: a firm, detailed, and consistent framework shot through with unfinished edges (termed fractures) that invite and support the reader's response in the form of continuation. These unauthorized extensions literally transform active reading into writing, while their presence recursively solidifies the fictional universe's imaginary space, further buttressing its autonomous existence. Such narrative reinforcement troubles many critics because an independent fictional reality not owned solely by a primary creator has disruptive implications for textual properties and copyrights. Nevertheless, these unauthorized continuations are the tangible artifacts of invested, pleasurable, and embodied reading, a type of reading and pleasure that is itself a revelatory form of literary criticism. Classifying texts in terms of their readers' desire to enter into and extend the narrative world encourages an understanding of these texts as evolving objects that must be categorized and described not just statically, but also dynamically, in terms of their capacity to generate. Three distinct (though occasionally intersecting) kinds of source-texts are identified here; the first locates the source's imaginary space as a narrative of place, the second as a narrative of society, character, and people, and the third as a narrative of interstices. Narratives of place such as Sir Philip Sidney's Arcadia evoke fantasies of exploration and colonization; narratives of society like Jane Austen's Pride and Prejudice call forth fantasies of unveiling; and narratives of interstices such as J.K. Rowling's Harry Potter series, as well as various long-running television programs, endorse fantasies of dimensionality and dialogue. An examination of these fantasies of continuation from 1590 to 2011 reveals a cyclical pattern in the reception of derivations and continuations. After the Romantic privileging of originality in the eighteenth and nineteenth centuries, the postmodern conception of creativity once more begins to resemble the more collaborative vision of the early modern period, a perspective which produces a queer, non-normative, multiplicitous, and post-canonical understanding of literature and fiction.

    Abstract:

    Lexical organization in individuals with Autism Spectrum Disorders (ASD) is not fully understood. This study investigated the nature of word association in individuals with ASD using two experimental paradigms: a word association task (Experiment 1), followed by an individualized semantic priming task (Experiment 2). In Experiment 1, participants were asked to name as many semantically related words as possible when auditorily presented with a target (e.g., participants heard the word cat and were asked to name semantically related words, within 60 seconds). In Experiment 2, participants were asked to name a target picture, preceded in time by 50 ms. Four types of auditory primes were used: Associated (e.g., bird-nest), Individual Semantic (e.g., bird-(tree)), Identity (e.g., bird-bird), and Unrelated (e.g., bird-car). The primes in the Individual Semantic condition were semantic associates obtained from responses in Experiment 1. Participants were 15 individuals with ASD (aged 14;0 to 19;2), 16 with typical language development matched for chronological age (CAM) (aged 15;0 to 19;7), and 14 with typical language development matched for raw score (VM) on the Peabody Picture Vocabulary Test 4th ed (aged 8;1 to 13;4) (Dunn & Dunn, 2007). In Experiment 1, while individuals with ASD produced many appropriate word associations, they also produced more unrelated word associations than both control groups. In Experiment 2, participants' reaction times revealed that individuals with ASD performed similarly to both control groups in all conditions: they exhibited priming in the Identity condition, but not in the Associated and Individual Semantic conditions. Absence of group x condition interaction in the Associated condition calls method into question. Results from Experiment 1 suggest that individuals with ASD have a similarly organized lexicon (i.e., more associated than unrelated responses to a given target), but the breadth and depth of their lexicons may be immature (i.e., higher proportion of unrelated responses, relative to both control groups). Findings have clinical and educational implications for vocabulary instruction in individuals with ASD. Word associations may first appear to be typical. However, in-depth analyses (i.e., monitoring associated, perseveration, proper noun, phrase, or unrelated responses), provides robust information regarding lexical organization.

  • A Behavioral and Biopsychological Investigation of the Role of the Illusion of Control and Perseverative Chasing Between Problem and Non-problem Gamblers

    Abstract:

    The illusion of control is associated with problem gambling. The perception that one is in control of a random event, when in reality there is no control, can facilitate problem gambling behaviors. The degree or extent of control may activate physiological mechanism of increased excitation and reward that reinforce gambling. In the studies presented here, performance on simulated gambling tasks that provided varying levels gambling participation were compared to physiological measures of behavioral activation in problem gambler and nongamblers. Participants watched video clips of three horseraces scenarios that permitted different degrees of participation and control over wagering. Concurrently saliva samples were collected throughout the experiment. Salivary cortisol levels, a glucocorticoid produced in response to hypothalamic-pituitary-adrenal (HPA) axis activation, were increased in problem gamblers in comparison to nongamblers when they were permitted unrestricted wagering. This study provides evidence that that gamblers produce higher levels of salivary cortisol than nongamblers, only when the illusion of control is present within the gambling session. There was no difference between problem gamblers and nongamblers in cortisol production with wins or losses. No correlation was found between participants' ratings of excitability, desirability of control, and production of salivary cortisol and gambling status. In addition, levels of risk-taking and perseverative chasing (chasing after one's losses) were measured using the Balloon Analogue Risk Task using a population of gamblers and nongamblers. Gamblers were found to be both riskier and more likely to chase their losses than nongamblers. The research reported in this dissertation provides support for the hypothesis that the illusion of control and perseverative chasing are two important factors that facilitate problem gambling behavior. Given these findings, treatment strategies for problem gambling may include methods for addressing these important determinants of the behavior.
