The Effects Of Rumination On Problem-Solving Self-Efficacy And Self-Efficacy For Controlling Upsetting Thoughts In The Context Of Depressive Symptoms, Christina Marcia Gilliam

Dissertations

Two cognitive variables that are of interest in their role in depression are self-efficacy and rumination. Self-efficacy refers to individuals¿ own appraisal of their ability to successfully accomplish a domain of tasks (Bandura, 1977). Rumination, as defined by Response Styles Theory (Nolen-Hoeksema, 1991), refers to the process of repetitively and passively thinking about negative emotions, consequences, and symptoms of distress. Although the relationship between these two constructs and depression has been examined in both experimental and correlational studies, there has been minimal research on the relationship between self-efficacy and rumination among depressed individuals. The present study was intended to replicate …

Constructing Meaning Through Religious Coping: Rebuilding The Shattered Assumptive World Of Mothers Bereaved By Homicide, Accident, And Illness, Laura Thea Matthews

Dissertations

Researchers have begun to examine the theory that religion may help bereaved individuals to provide meaning to an otherwise inconceivable event. In addition, work by Janoff-Bulman (1989; 1992) and others (see Kauffman, 2002) has spawned a growing understanding that bereavement forces individuals to restructure and rebuild previously held assumptions about the self and the world. This study examined mediator-moderator effects of positive and negative religious coping on relationships between grief intensity and world assumptions in 117 mothers bereaved by the death of a child (homicide, illness, or accident). Mothers with higher grief intensity rated the world as less meaningful and …

The Impact Of Sexual Abuse And How Children Cope: Different Perspectives From Caretakers And Children, Megan M. Schacht

Dissertations

Child sexual abuse is a complicated stressor with a broad range of associated symptoms. It has been suggested that the coping techniques children utilize may act as a mediating variable in the relationship between child sexual abuse and subsequent difficulties. Until recently, child sexual abuse sequelae were assessed in a piecemeal fashion, with individual tests for each symptom domain and reporter. However, recent developments in the area of trauma assessment have provided researchers with complementary caretaker- and self-report measures to assess a broad range of trauma-related symptoms (i.e., the Trauma Symptom Checklist for Young Children [TSCYC] and the Trauma Symptom …

Is Rumination General Or Specific To Negative Mood States? The Relationship Between Rumination And Distraction And Depressed, Anxious, And Angry Moods In Women, Jessica Lauren

Dissertations

Rumination has been found to play a role in negative affect by either maintaining or increasing depressive, anxious, and angry moods, whereas distraction has been found to decrease these negative moods. This experiment tested the hypothesis that the effect of rumination occurs across mood states and is not specific to one type of negative mood, using both Nolen-Hoeksema¿s Response Styles Theory (RST; 1991), and Bower¿s Associative Network Theory (1981; ANT). The impact of rumination and distraction on depressed, anxious, and angry mood states were examined in 90 women at the University of Missouri ¿ St. Louis. Participants were randomly placed …

Exposure Of Nervous System Cells To Polychlorinated Biphenyls (Pcbs), Results In Alterations Of Neurotrophic Factor Expression, Gordon H. Gurley

Dissertations

Toxic insult by PCBs results in learning and memory deficits in humans. Alterations in expression of neurotrophic factors (NF) and/or their receptors have been linked to changes in learning and memory. How PCBs affect cognition is not known. We suggest that PCBs affect cognition by altering NF expression.

We exposed cultured C6 rat glioblastoma cells (an astrocyte cell-line) to medium containing PCB (Aroclor 1254 (10ppm)). Control cells were treated with dimethyl sulfoxide (DMSO) or regular medium. Enzyme-linked immunosorbent assays (ELISA) were used to determine glial cell-line derived neurotrophic factor(GDNF) and nerve growth factor (NGF) concentrations in all samples. We also …

This study showed no significant difference in body weight, length and metamorphic rate.

Second, I used DNA microarrays to examine mRNA expression levels of genes in atrazine treated and control Xenopus laevis tadpoles. I found significant changes in gene expression levels of 18 genes. These …

Providing Uninsured Adults With Free Or Low-Cost Primary Care: Does It Influence Their Use Of Hospital Emergency Departments?, Anne G. Zahradnik

Dissertations

This study analyzes one component of the health care safety net to determine whether or not being enrolled in a free or low-cost primary care physician access program subsequently affects emergency room utilization by uninsured adults ages 18 through 64. Those individual decisions are analyzed from both public goods and rational choice schemas. Additionally, physician access programs of different formats (a low-cost physician referral program and a freewalk-in clinic) are analyzed and compared for relative effectiveness. The study is a quantitative analysis of more than 40,000 individual patient records rather than relying on qualitative patient recall or on analyzing broad …

The Representation Of Race And Ethnic Relations In Japanese Junior High School English Language Textbooks From 1987 To 2002, Mieko Yamada

Dissertations

This dissertation explores how cultural attitudes about race/ethnicity are taught and how international power relations are expressed in Japanese junior high school textbooks. In a content analysis of Japanese junior high school textbooks in English as a foreign language, I examine how race and ethnic relationswere expressed and what types of interracial communication took place in the textbooks. Applying the racial formation theory developed by Omi and Winant (1994) and the concept of color-blind racism by Bonilla-Silva (2001, 2003), I explain how cultural ideology towards racial and ethnic relations were guided in the Japanese English language textbooks.

Fifteen English language …

Nurse Practitioner Adoption Of Clinical Innovations, Rhoberta Jones Haley Phd

Structural Auditing Methodologies For Controlled Terminologies, Hua Min

Dissertations

Several auditing methodologies for large controlled terminologies are developed. These are applied to the Unified Medical Language System XXXX and the National Cancer Institute Thesaurus (NCIT). Structural auditing methodologies are based on the structural aspects such as IS-A hierarchy relationships groups of concepts assigned to semantic types and groups of relationships defined for concepts. Structurally uniform groups of concepts tend to be semantically uniform. Structural auditing methodologies focus on concepts with unlikely or rare configuration. These concepts have a high likelihood for errors.

One of the methodologies is based on comparing hierarchical relationships between the META and SN, two major …

Female Hormonal Influences On Stress- And Drug-Induced Reinstatement Of Extinguished Amphetamine-Induced Conditioned Place Preference, Melissa Elaine Bleile

Dissertations

One Animal paradigm used to study addiction is conditioned place preference. CPP is achieved when an animal develops a preference for environmental stimuli previously paired with subjective effects of a rewarding drug. Women may experience greater drug sensitivity than men, most likely due to estrogen levels. The purpose of this experiment was to assess the effects of female sex hormones on drug sensitivity and their interaction with the primary factors causing relapse, stress or drug re-exposure. Female rats were ovariectomized and received replacement hormones to control circulating hormone levels. These groups of animals were tested for amphetamine (AMPH)-induced CPP and …

Evolutionary Epidemiology Of Endemic Gal¿Pagos Birds And Their Parasites, Noah Kerness Whiteman

Dissertations

In order to better understand parasite diversification, I went to the Gal¿pagos Islands to study the ecology and evolution of a model bird-parasite system, which included four phylogenetically independent ectoparasite lineages infecting the Gal¿pagos Hawk (Aves: Buteo galapagoensis). The parasites comprised two lice (Insecta: Phthiraptera: Amblycera, Ischnocera), a lousefly (Diptera: Hippoboscidae) and an avian skin mite (Acari: Epidermoptidae). Ultimately, my goal was to examine ectoparasite evolutionary epidemiology and disease susceptibility in relation to the host¿s ecological and colonization history. At the outset, I hypothesized that parasite natural history was key in influencing the coalescent process. Accordingly, I found differences …
