Cell Biology Of Foxp3+ Regulatory T Cells, Mariko Takami

Dissertations

T cells play a central role in the immune response to fight against pathogens and orchestrate other immune cells. An overreactive immune response can lead to autoimmune diseases, therefore the immune system must possess negative regulation mechanisms. In the periphery, naturally arising regulatory T cells (nTregs) negatively regulate immune responses and play an important role in maintaining immune homeostasis. When antigens are present, conventional CD4+ T cells recognize their cognate antigen and proliferate. After pathogen clearance, expanded effector T cells eventually decline in number due to activation induced cell death (AICD) to terminate immune response. However, it is not understood …

One Sex, One School, Who Wins: How Single-Sex Learning Environments Impact Educational Attainment, Socio-Emotional Health, And Ambitions, Bradley Kirshenbaum

Master's Theses

Research on single-sex schools has covered a variety of matters regarding the effectiveness of their programs. This paper examines research on single-sex schools over the past 30 years in an effort to harmonize the past discourse with present trends. Journal articles and government research were used to synthesize the variety of methods used to ascertain whether single-sex schools have a positive influence on boys, girls, or both parties. Research trends have overwhelmingly supported all-girls schools, while remaining skeptical of any positive influence on boys. Much of the research supporting all-girls schools also suggests that single-sex schools' benefits are applicable to …

Perceived Partner Commitment And Implicit Self-Esteem Predicts Connectedness Accessibility In Response To Relationship Threat, Norma L. Reyes

Master's Theses

The current research examined the impact of perceived partner commitment, implicit self-esteem, and relationship threat on connectedness. The present study predicted that individuals with high (versus low) implicit self-esteem are more likely to access connectedness goals (on an unconscious level) after experiencing a relationship threat, when they perceive their significant others are highly committed to the relationship. This relation between implicit self-esteem and connectedness goal accessibility will not be evident in the control condition. The findings reveal perceived partner commitment moderated the relation between implicit self-esteem and relationship threat on accessing connectedness goals. However, people with high implicit self-esteem were …

Illinois Mental Health Courts: Intra-Group Dynamics In The Courtroom Work Group, Shanti J. Raman

Master's Theses

This study was intended to gain insight into key social psychological constructs in an unexplored work-group context: one premised on true team structure. Exploratory information on intra-group dynamics in Illinois mental health courts addressed levels of trust, communication, coordination, efficacy, and conflict resolution within mental health court teams.

A survey assessed how court group members associate these central variables with their teams. All reported relatively high levels of trust and team efficacy, and solid capacities for communication, coordination, and conflict resolution. No notable differences emerged in these variables relative to length of courts' operation. Team members from multiple disciplines held …

Effects Of Binge Alcohol Exposure On Canonical Wnt Signaling During Fracture Repair, Kristen Leigh Lauing

Dissertations

Excessive alcohol consumption is associated with increased fracture risk, delayed bone healing and fracture non-union. Binge alcohol consumption has occurred in 25-40% of all orthopaedic trauma cases. The canonical Wnt pathway, through tight regulation of stabilized beta-catenin, plays an essential and pivotal role in the formation of new bone and cartilage to initiate bone repair. We sought to determine the molecular mechanisms behind alcohol-related fracture complications by testing the hypothesis that binge alcohol exposure deregulates canonical Wnt signaling in the fracture callus, leading to impaired healing.

To test this, C57BL/6 or beta-catenin/TCF-reporter male mice were exposed to intraperitoneal alcohol or …

Gender Differences In Depressive Symptoms: The Interaction Of Cognitive Avoidance Coping And Specific Stressor Domains During Freshmen Adaptation To College, Daniel Dickson

Master's Theses

The first year of college can be a stressful experience that can lead to depressive symptoms in emerging adults. Due to the significant impairments that are associated with depressive symptoms across the lifespan, it is important to understand the elements of the first-year college experience that contribute to depressive affect. The goals of the current prospective study are to examine sex differences in the relationship between life stressors (i.e., social and achievement stressors) and cognitive avoidance coping in the development of depressive symptoms in first-year college students. The findings suggest that although cognitive avoidance is predictive of more depression, there …

Team Performance On A Computerized Intellective Task, Joseph Bihary

Master's Theses

This study examined the effects of a reflexivity manipulation on the performance of dyads and triads working on an intellective task known as letters-to-numbers. Past research has shown triads consistently outperforming dyads on this task. The current study sought to determine whether giving dyads an opportunity to reflect on strategy would close this gap in performance. Participants performed a computerized version of two letters-to-numbers problems in dyads or triads. Between problems, half of the groups performed a reflexivity task designed to facilitate strategy improvements. Experimental sessions were videotaped. It was predicted that triads would outperform dyads, reflexivity groups would outperform …

Exposure To Community Violence And Social Maladjustment Among Urban African American Youth: The Role Of Emotion Dysregulation, Devin Colleen Carey

Master's Theses

The goal of the present study was to further previous research that has focused on the detrimental outcomes of violence exposure by identifying the mechanisms that influence children's psychosocial vulnerabilities. Specifically, it examined emotion regulation as a possible mediator of community violence exposure to social adjustment. Moreover, because of the evidence that children living in inner city communities are chronically exposed to violence, this study longitudinally explored the reciprocal and perpetuating relationship between exposure to violence and child social maladjustment. Participants were 268 African American students (M age = 11.65 years, 40% males and 60% females) from six inner city …

The Development Of Trust In The Nurse-Patient Relationship With Hospitalized Mexican American Patients, Sharon M. Jones

Dissertations

The Hispanic population in the United States is growing and this population experiences health care disparities compared to non-Hispanic Whites. Mexican Americans are the largest sub-group of Hispanics and providing nursing care that is patient-centered and culturally competent is important when caring for this population. Trust is an important component of patient-centered care and culturally competent care as well as a major element , (confianza) in the Hispanic culture. Although nursing researchers have identified the need for trust in culturally competent care with Mexican American patients, none have explored how trust develops between the nurse and the Mexican American patient. …

Balkan Minds: Transnational Nationalism And The Transformation Of South Slavic Immigrant Identity In Chicago, 1890-1941, Dejan Kralj

Dissertations (1 year embargo)

At the start of the twentieth century, America was inundated with unskilled workers eager to fuel the engines of the new economy. The South Slavs of the Balkans joined countless others from the furthest corners of the European continent during the final years of the nineteenth century and first two decades of the twentieth. Millions of foreign and unfamiliar faces, outlandishly clad, replaced the previous fair-haired and fair-skinned Western Europeans that originally populated the nation. These innumerably diverse peoples of eastern and southern European origin redefined the character of twentieth-century America.

The vast majority of South Slavic immigrants arrived in …

To examine elementary school teachers' reasons for staying in their current schools a quantitative …

Building A Climate That Supports And Protects Mandated Reporters: School Principals And Their Perceived Roles And Policies And Procedures In K-8 Schools, Gina Bartucci

Dissertations

Schools are designed to be safe and healthy places for children to grow and learn, and principals are the instructional leader charged with creating this climate. The role of the mandated reporter, which is the role assigned to all individuals who work in schools, is intended to protect children. The mandated reporter is supposed to be the voice for children-not just for the child who actually speaks out against the individual who is perpetrating against them, but also for the child who does not have the words to report the abuse. A suspicion is all a mandated reporter needs to …

Cultural Competence--Does It Matter?: Lessons From A Mixed-Methods Study Of Wraparound Practice, Jennifer James Rose

Dissertations

This mixed methods study investigated whether caregivers' ratings of wraparound fidelity and satisfaction with the wraparound process differed based upon their facilitators' self-assessed cultural competence and caregivers' reported stress. An explanatory sequential design was used. The quantitative phase was completed first. Survey methodology was used to measure reported cultural competence, wraparound fidelity, satisfaction with the wraparound process, and parental stress. Facilitators (n=58) completed a self-assessment instrument, the Multicultural Counseling Knowledge and Awareness Scale (MCKAS; Ponterotto, 1997). The MCKAS survey yielded a 43% response rate. The MCKAS descriptive data found levels of reported cultural competence comparable to previously published studies. Telephone …

Positive Emotions And Immune Respose To Influenza In Medically Stable Older Adults, Maryann J. Gierloff

Dissertations

Influenza results in substantial human suffering and health care costs. Evidence from psychoneuroimmunology suggests that emotions influence the immune system and may alter susceptibility to infectious diseases, like influenza. The purpose of this investigation was to evaluate the influence of psychological factors, health behaviors, circulating levels of proinflammatory cytokines and the development of influenza-like illness in older adults. Medically stable participants, 55 years of age and over, were enrolled from the general community and an elderly community. Psychological factors (emotions and perceived stress), health behaviors (sleep and physical activity) and plasma cytokine levels (IL-6 and IL-1B) were evaluated with respect …

Social Cognitive Functioning And Social Competence In Children And Adolescents With Spina Bifida And Hydrocephalus: Social Cognitive Neuroscience As A Model, Caitlin Reid Roache

Dissertations

The purpose of the current study was to examine social cognition in children with spina bifida and congenital hydrocephalus (SBH) and to determine whether deficits in these domains are associated with poor social competence, utilizing concepts from social cognitive neuroscience. To build upon extant literature, multi-method assessments, multi-informant data, and a developmental, biopsychosocial perspective were utilized. Distinct aspects of social competence, as defined by social performance, social skills, and social adjustment, were considered.

The current study was designed to investigate: (1) differences in social cognition between children and adolescents with SBH and the general population, (2) potential neuroanatomical predictors of …

Nietzsche's Theory Of Cognition: An Interpretation And Defense Of Perspectivism, Justin R. Marquis

Dissertations

Friedrich Nietzsche has long been recognized as a pivotal thinker in the history of moral philosophy, but until the last quarter century his importance for our understanding of the concepts of truth and knowledge had been largely ignored in English-language scholarship. In my dissertation, I add to the growing discussion on Nietzsche's theory of human cognition. While more attention has recently been given to this dimension of Nietzsche's thought, several key aspects have been largely ignored or insufficiently treated including the effects that the ethical or evaluative domain have on the way we cognize the world, the role that radical …

Are We Having Fun Yet? Savoring, Type A Behavior, And Vacation Enjoyment, Jennifer L. Smith, Fred B. Bryant

Psychology: Faculty Publications and Other Works

Although studies of Type A behavior ceased in the early 1990s because of failures to replicate its connections with heart disease, the Type A behavior pattern of speed, impatience, perfectionism, drivenness, and hostility may nevertheless be important in understanding individual differences in the subjective quality of life. The present study tested the hypothesis that Type A behavior undermines the enjoyment of leisure time and that this detrimental effect is mediated by savoring responses that hamper enjoyment. Confirming hypotheses, analysis of self-report survey data (N = 764) revealed that: (a) higher levels of Type A impatience in social situations predicted …

Empirically Supported Treatment Interventions For Persons With Posttraumatic Stress Disorder And Comorbid Borderline Personality Disorder, Megan Seliga

Dissertations

The overall stigma- and gender-related controversies that surround the diagnosis of Borderline Personality Disorder (BPD) present a unique ethical mandate to the practitioner. The relationship between trauma and the BPD diagnosis strengthens the need for carefully designed treatment interventions in order to secure the benefits of trauma-focused work, while minimizing the risk of undue regression. The complexity and risk of harm introduced by a diagnosis of comorbid BPD and PTSD urges the need for clarification of optimal treatment interventions to guide practitioners. Trauma-focused therapies, particularly EMDR, tend to be the treatment of choice for PTSD; however, comorbid borderline pathology has …

A Qualitative Exploration Of African American Men's Attitudes Toward Marriage, Rabiatu Barrie

Dissertations

The decline in the rate of marriage in the African American community has been documented in both the empirical literature and pop culture. Initially researchers postulated that the upward mobility of African American women had diminished their to marry, but studies found opposing evidence to that theory and so the focus switched to African American men. Early studies about African American men and marriage indicated that the sex-ratio imbalance, the educational disparity between African American men and women that leads to economic frailty was the major cause of the disparity in marriage (James et al 1999, Davis, Emerson, & Williams, …

A Structuralist Controversy: Althusser And Lacan On Ideology, Won Choi

Dissertations

Slavoj Zizek argues that, if Althusser was an adamant structuralist who reduced subject to a mere function of ideology, Lacan was a genuine critic of such a position, who showed how the subject can separate itself from the symbolic structure of ideology. Zizek's portrayal of the debate, however, is not only based on a misapprehension of Lacan's own theory but also fails to notice that, when the two theorists collided on the question of structuralism in the late 1960s, the issue was not the separation, but how ideology as a social practice is to be situated in relation to other …

Protective Factors Against Intergenerational Conflict In Chinese Immigrant Families: A Pilot Study, Xiaoyan Fan

Dissertations

This pilot study examined some potential protective factors which may mitigate the effects of the acculturation gap on intergenerational conflict in 23 Chinese immigrant families. Adolescents and one of their immigrant parents completed questionnaires assessing their acculturation. Adolescents also completed family conflict and parent attachment measures. Parents provided information on the use of social support and the communication on the cultural differences between American culture and Chinese culture in the family by completing related measures. It was expected that acculturation gap would predict parent-child conflicts in immigrant families, and the relationships between acculturation gap and parent-child conflict would be moderated …

The Relationship Between Infant Crying And Father Well-Being, Leslie Katch

Dissertations

Infant excessive crying and fussing has been linked to adverse maternal outcomes such as increased depression and stress, and decreased feelings of parenting self-efficacy. Infant crying has also been identified as the number one trigger caregivers report prior to an abusive action, placing infants who cry excessively at risk. Fathers and male caregivers have been identified as the primary offenders in the majority of infant abuse cases, suggesting a particular risk between fathers and infants who cry excessively. However, the relationship between excessive crying and fathers has not been explored to the same extent as mothers. In an effort to …

Acute-To-Home Care Nursing Handoffs: Distributed Cognition Across Patterns Of Knowledge, Rosemary Kennedy

Dissertations

Timely, explicit, and effective communication of patient information during care transitions is fundamental to safe care. Studies show that handoffs or transfers of patient care from one provider to another are susceptible to communication failures (Riesenberg et al., 2009a). Most studies on communication failures focus on communication between providers within the same setting of care. Few studies, if any, focus on communication between care settings in different locations. However, research has identified gaps in care during critical transitions and identified poor communication and incomplete transfer of information as the root cause (Naylor et al., 2004). This qualitative dissertation consists of …

Shades Of Grey: An Exploration Of The Student Learning Experience In Diagnostic Radiology Education, Kathleen Linda Linaker

Dissertations

Diagnostic radiology education is a specialty within healthcare education and encompasses education at both the undergraduate and resident level.
