Effects Of Subchronic Dietary Lead Exposure On Dmtp And Dnmtp Performance In Fisher 344 Rats, Joshua D. Vardigan

Masters Theses

Recent attention has focused on the possibility that even low-level Pb exposure can produce subtle neurological impairments in the absence of overt signs of toxicity. Previous behavioral assessments of learning and memory using DMTS procedures have documented learning impairments in monkeys exposed to Pb during early postnatal development, and although a variety of operant behavioral assays have documented detrimental effects of dietary Pb treatment in rats, the DMTS procedure has not been examined in rats following short-term low levels of Pb through dietary exposure. Thus, the objective of this study was to measure the degree of cognitive impairment produced by …

Modulatory Efferent Morphology And Target Allocation With Co-Innervating Leech Motor Neurons, James Melchior

Masters Theses

The leech, Hirudo, has two efferents that converge upon the heart tube (HT) muscle; the segmentally iterated heart excitor motor neurons (HE), and the modulatory heart accessory neurons (HA). Using intracellular dye injections and antibody labeling, we were able to visualize and distinguish the morphologies of these two efferents. We found that HA(5) provides dense coverage of the anterior segments of heart tube muscle and extends along the HT into the posterior segments 6 and 7, while HA(6) projects centrally for several segments before extending into the periphery. HA(5) and HA(6) homologs show little or no overlap on HT …

Phenomenological methodology was used to explore immigrants' lived experiences and hear their voices both individually and …

An Unequal Consumption? Sex And Gender Differences In Tuberculosis, Sarah K. W. Avink

Masters Theses

In the developing world today, tuberculosis (TB) accounts for 26% of avoidable deaths (Holmes et al 1998). Poverty is considered to be a main risk factor for TB, and since some estimates show that women make up 70% of the world's poor (Thorson and Diwan 1998:11), one might conclude that the incidence of TB worldwide would be much higher for women than men. However, reports reviewed in this thesis show the reverse to be true, with an adult annual male notification ratio for TB at 1.5 to 2.1 times higher than that of females. Both biological reasons and social factors …

Functional Assessment Of Problem Behavior In Children With Autism Spectrum Disorders: A Review Of 32 Cases, Jessa R. Love

Masters Theses

The prevalence of autism spectrum disorders among children aged 4 to 17 years is approximately 5.5 to 5.7 out of 1000 children (Centers for Disease Control, 2006). It is not uncommon for children with these disorders to display a wide range of problem behavior (e.g., Farrar-Schneider, 1992; Oswald et al., 1992). While a number of studies have reported aggregated data on the reinforcement functions of such problem behavior, none have reported the distribution of functions with a sample comprised solely of individuals on the autism spectrum. Thus, the purpose of this study was to examine individual client data from an …

Perceptions Of Adolescents: Preferences Of Adolescents For Parental Presence And The Effect On Information Disclosure, Bethany Barrus

Masters Theses

Adolescents born with a cleft lip or palate are in a unique position because they have received a lifetime of interdisciplinary team care where decisions are frequently made by parents, yet they are transitioning into a stage of life in which they will make their own health related decisions. Because of the complexity of their health needs, the preferred method of care is interdisciplinary team care (Nackashi, Dedlow, Dixon-Wood, 1997; Kummer, 2001). Little research has been conducted regarding the perceptions of adolescents with oral cleft about their care and issues of confidentiality in the context of team care. This study …

The Use Of Verbal And Written Emotional Expression For Empowerment And Healing In Clinical Social Work Practice, Laurie Lynn Dix Schmit

Masters Theses

Social work practice often demonstrates ambivalence about emotions and emotional expression. Forced by managed care to keep clinical work short-term, and having removed the depth of psychoanalytic and other psychodynamic approaches, social workers have retreated from attending to the emotional life of clients, and now focus mainly in the realm of thoughts and behaviors. By integrating literature from other disciplines with social work, and incorporating contemporary thought on the topic, this paper addresses the importance, challenges and rewards of utilizing emotional expression in clinical social work practice. We find that, by addressing the emotions of our clients, we begin to …
