The Effect Of Early Life Photoperiod Manipulation On Cocaine-Induced Behavioral Sensitization In Male And Female Japanese Quail, Shannon Elizabeth Eaton

Theses and Dissertations--Psychology

Estrogens seem to play a role in the locomotor activating effects of cocaine. Japanese quail provide a good model for hormonal manipulation as alterations of their photoperiod controls hormone levels. The current study aims to examine the role of early life photoperiod manipulation in cocaine-induced behavioral sensitization in quail. It was expected that if quail were raised on a short photoperiod, they would have a reduction in gonadal hormones and this reduction in hormones would affect the acquisition of cocaine-induced behavioral sensitization. Quail were raised on an 8L:16D or a 16L:8D light cycle. Following 2 days of habituation, quail were …

Cocaine Choice: A Novel Procedure For Investigating Neuronal Activation Mediating Cocaine Preference, Jonathan Jenn-Sheng Chow

Theses and Dissertations--Psychology

Cocaine use disorder is a significant health problem, negatively impacting individuals afflicted. While preclinical self-administration research has provided invaluable insight into the neurobehavioral mechanisms that underlie cocaine abuse, cocaine use outside of the laboratory occurs within an environment where other goods are also available ubiquitously. Although there is an ever-increasing literature investigating drug vs. non-drug choice in rodent models and how alternative goods can compete with the subjective value of cocaine, the neurobiological mechanisms that are associated with cocaine preference remains largely unknown. Additionally, current drug vs. non-drug choice studies use procedures that confound preference with intake, such that preference …

A Mixed Methods Sequential Explanatory Study Of Male Farmers' Health Beliefs, Attitudes And Practices In Rural Kerry, Chrystal O'Brien

Theses

Aim/Background: Beliefs and attitudes about health directly and indirectly influence concomitant behaviours, practices and health outcomes. In Ireland, male farmers are experiencing a disproportionate burden of ill health in preventable lifestyle diseases, yet there is a lack of behavioural research in relation to male farmers and their health. Therefore, the purpose of this study was to examine the health beliefs, attitudes and practices of male farmers in rural Kerry, and to explore healthcare professionals' insights of male farmers' health beliefs, attitudes and practices.

Methodology: The study adopted a mixed methods design. Phase one of the study involved structured interviews with …

The Hold Me Tight Program For Couples Becoming Parents: A Mixed Methods Study, Debbie Wang

Theses and Dissertations (Comprehensive)

ABSTRACT

Attachment theory has made substantial contributions to the understanding of close relationships. The purpose of this study was to inquire whether an attachment-informed psychoeducational program is a feasible and effective intervention for couples expecting their first child. The overarching question was: Is an attachment-informed relationship enhancement program, such as Hold Me Tight^® (HMT), helpful to couples in strengthening their relationship and increasing their confidence in becoming first-time parents? The research question was addressed using a mixed-methods approach.

In the first phase, the Hold Me Tight^® program developed by Dr. Sue Johnson was modified for use with couples …

Spatial Modelling And Wildlife Health Surveillance: A Case Study Of White Nose Syndrome In Ontario, Lauren Yee

Theses and Dissertations (Comprehensive)

Wildlife data is often limited by survey effort, small sample sizes, and spatial biases associated with collection and missing data. These factors can create unique challenges from a surveillance perspective when trying to extract spatial patterns of habitat suitability and disease distributions for conservation and management purposes. This thesis examined data quality from a wildlife health database in the context of spatial analysis of wildlife disease. Spatial analysis of the data to predict habitat suitability of bats and white nose syndrome afflicted bats was examined by using the MaxEnt modelling method. Methods to reduce spatial bias were examined and specific …

Hepatitis C Testing And Treatment Access Among People Who Inject Drugs, Monika Roerig

Theses and Dissertations (Comprehensive)

Hepatitis C (HCV) remains a global issue as it affects 2-3% of the world’s population. Despite Canada’s universal access to healthcare, barriers to accessing testing and treatment for HCV has contributed to approximately 250,000 Canadians living with chronic HCV. People who inject drugs (PWID) account for about 60% of all HCV cases in Canada, making them the primary target for public health interventions, namely prevention and harm reduction. Harm reduction efforts have proven effective to reduce the incidence of infectious diseases and to prevent overdoses, but there remains a large proportion of individuals living with the virus who are unaware …

The Effects Of Two Different Sports Drinks On Rpe And Finishing Speed Of An Endurance Run In Highly Trained Distance Runners, Matthew J. Feldhake

Masters Theses

The purpose of this study was to compare the effects of a protein-containing sport drink with a traditional non-protein sport drink has on ratings of perceived exertion (RPE) and finishing speed of an half marathon. Of the possible factors that would support including protein in a sport drink the primary one was its inhibitory effect on serotonin release in the brain. This could help attenuate perceived exertion, thus allowing individuals to compete at a higher level for longer durations (Davis, Alderson, & Welsh, 2000).

This study was conducted using nine members of the Eastern Illinois University Men's Cross Country team. …

Readiness For Assisted Decision-Making: An Exploratory Qualitative Study, Kay Cronin

Theses

Background: Ireland has recently enacted the Assisted Decision-Making (Capacity) Act 2015. The enactment of the legislation has allowed Ireland to ratify the United Nations Convention on the Rights of People with Disabilities (2008). The convention obliges all member states to assist people with disabilities to make their own decisions, with their will and preference taking precedence over what others deem to be in their best interests. Implementation of this legislation requires a change in working practice among health and social care providers to promote autonomy and decision-making among service users. To date, this topic has not been researched in Ireland. …
