Migratory behaviour and survival of wild and hatchery coho salmon using acoustic telemetry

Chittenden, Cedar Marget 05 1900 (has links)
Climate is emerging as a primary determinant of marine survival and migratory behaviour for Pacific salmon. For example, a regime shift in the mid-1990s was correlated to a major change in the migratory behaviour of coho salmon (Oncorhynchus kisutch) in the Strait of Georgia, BC. The details of this new behaviour pattern remain relatively unknown. Furthermore, many coho stocks have been declining during the past three decades. Mitigative strategies –such as hatchery programs— have done little to reverse the trend, and little is known about how hatchery fish are affecting wild populations. The objective of this dissertation was to identify key mortality areas and provide the first look at the migratory behaviour of juvenile wild and hatchery coho in southwestern British Columbia using new telemetry technologies. As coho pre-smolts are relatively small compared with other salmonid species that are typically studied using acoustic telemetry, the identification of the appropriate sizes of fish and tags to use was critical. The first study tested the effects of surgically implanting the three smallest sizes of acoustic tags available on the growth, survival, performance and condition of coho pre-smolts. The first of three field studies to follow investigated the early migratory behaviour and survival of an endangered coho population. The second field study examined differences in physiology, survival and migratory behaviour between wild and hatchery-reared coho smolts. Finally, the third study analysed the altered marine migratory behaviour of juvenile coho in the Strait of Georgia. This dissertation provides the first evidence of high freshwater mortality rates in the endangered coho population, which has implications for the management and conservation of this and other at-risk stocks. I found differences in migratory behaviour and physiology between wild and hatchery-reared coho, suggesting that mitigative strategies need further evaluation. Finally, the timing of the anomalous coho migration out of the Strait of Georgia confirmed that population changes in the strait are a consequence of ecosystem-related impacts. These findings demonstrate how new technologies could be used to fill major information gaps and improve the management and conservation of Pacific salmon.

Socioeconomic and Cultural Aspects of Overweight and Obesity in Georgia's African American Community

Simpson, Alicia C 25 April 2011 (has links)
According to the U.S. Department of Health and Human Services, Office of Minority Health and the Center for Disease Control (CDC), individuals who identified themselves as African-American or Black have the highest rate of obesity in the United States. The higher prevalence of overweight and obesity among the African-American population correlates to an increased risk for a number of diseases (including heart disease, diabetes, and several cancers) and an increased mortality rate for the African American population. Through focus groups and interviews, the research I will present focuses on perceptions of overweight and obesity among African-Americans, including any cultural beliefs associated with overweight, obesity and African-Americans. I examined cultural norms of body image, food preference (including "soul food" and other foods traditionally associated with African-American culture), and access to healthy foods and how the familial unit deals with issues of overweight and obesity. I also explored popular explanatory models surrounding the cultural acceptance of overweight and obesity in the African-American culture. Finally, I attempted to uncover the role that socioeconomic status plays in the acceptance, belief and/or knowledge of these models. A total of 80 participants who identify as African-American or Black were chosen using non-probability sampling techniques to participate in this research. I conducted 3 focus groups and 60 one on one interviews. Each participant in the focus group and one on one interview filled out a brief questionnaire about their perceptions of their own body image in conjunction with their interview. Varying socioeconomic status was sought amongst interview participants while similar socioeconomic status and education level were sought among focus group participants so that each person within the group felt as comfortable as possible sharing their experiences with weight and food. In my paper, I will discuss common themes that emerged in focus groups and interviews regarding perceptions of obesity among my participants.

Financial Exploitation of the Elderly: A Policy Review and Recommendations for Georgia

Haberlen, Melissa C. 20 December 2012 (has links)
Eleven percent of Georgians and 13.3% of all Americans are currently over the age of 65. The segment of elderly adults in the United States is the fastest growing subpopulation, attributed to both average lifespan increases and a significant aging of "the baby boomer generation". Thus it is increasingly important that health and policy professionals give attention to issues of health and well-being faced by the aging population. One such issue, financial exploitation of the elderly, has received a large amount of media attention and public concern over the last several years, due to a large increase in the recorded prevalence of the problem. It has been estimated by some studies that financial exploitation of the elderly occurs in 4-5% of the aged population. A variety of legislation, both state and federal, has attempted to address and curb the problem. Like many states, Georgia has successfully passed and implemented such legislation; however as numbers of exploitation continue to increase, it is clear that all states still require a number of policy changes in order to truly eliminate the problem. The purpose of this capstone project is to synthesize scientific research dedicated to financial exploitation of the elderly and, describe current policies in place to address this problem. Finally, policy recommendations for the State of Georgia will be offered so that response and prevention systems effectively reduce the occurrence of this crime.

An Analysis of Postpartum Depression and Care Seeking Behaviors in Georgia

Tennyson, Sarah Elizabeth 19 November 2009 (has links)
Postpartum depression is recognized as an important maternal and child health issue. Postpartum depression is the most common perinatal psychiatric disorder and one of the most common complications of childbirth. Studies show prevalence rates in women ranging from 10% to 25%. Postpartum depression affects the emotional wellbeing of mothers, infant behavior, mother-infant bonding, and marital relationships. However, the majority of women who experience postpartum depression do not seek care. The purpose of this analysis is to examine the demographic differences between women in Georgia who report symptoms of postpartum depression but do not seek care, versus women who report postpartum depression symptoms and seek care. Approximately 15% of respondents in this study reported postpartum depression. Of these women, approximately 80% did not seek care for their symptoms. This analysis found that women with the following characteristics were more likely to not seek care for depression: non-White and Hispanic women; women that were uninsured before their pregnancy; women that had their prenatal care paid for by Medicaid or the Military; and women who did not seek care for depression during their pregnancy. The results of this study may help to guide the implementation of public health interventions among postpartum women in Georgia.

Demographic Associations of Tobacco Use Among Georgia Secondary Students

Cowart, Michael G 05 December 2011 (has links)
As in years past, use of tobacco remains the leading cause of preventable death in this country. Smoking has been associated with elevated risks of 15 other forms of and has also been identified as a major cause of such chronic conditions as cardiovascular disease, cerebrovascular disease, bronchitis and emphysema. In 2008, an estimated 8.6 million Americans suffered from smoking-related chronic conditions (American Cancer Society, 2010). As 80% of tobacco use begins in adolescence (Villanti, Boulay & Juon, 2010), this age group has long been the focus of intervention efforts. Furthermore, animal studies suggest that the adolescent brain is at increased risk for developing an addiction to nicotine compared to an adult brain (Morrell, Song & Halpern-Felsher, 2011). Additional studies have demonstrated that the younger an adolescent begins smoking, the more likely he is to become a regular smoker and less likely to quit smoking (Brown et al., 2010). The public health opportunity for primary and secondary prevention intervention is clear. To track adolescent risk-taking in the state, The Georgia Department of Education administers the Georgia Student Health Survey II [GSHS II] throughout all school districts. The purpose of this thesis study was to examine known smoking risk factors using the GSHS data in order to assess associations using an adolescent sample. Findings demonstrated that age, gender, and urbanicity were associated with smoking. Findings from this study provide insights for programming that can be tailored to meet the needs of adolescent subgroups that may be vulnerable to smoking initiation.

Mineralogy and Geochemistry of the Bauxite Deposits (Cretaceous), Wilkinson County, Georgia.

Ayorinde, Adebayo O 07 May 2011 (has links)
Cretaceous bauxite deposits from Hall and Veneer mines, Wilkinson County, Georgia are composed of kaolinite, gibbsite, goethite, anatase, nordstrandite and bohemite. Quartz and micas are absent in the samples. The presence of boehmite and goethite are evidence of intense weathering forming the bauxite deposits. The extremely high values of the Chemical Index of Alteration (CIA) which is over 99, and the low values of the alkali metals and alkali earth metals, support an intense weathering origin for the bauxite deposit. There is evidence of deposition in the mines based on the presence of pisoids in the bauxite samples and the composition of the parent materials, which vary markedly by the non-uniform TiO2/Al2O3 values which represent the accumulation of transported materials from contrasting source areas. Kaolin minerals were first produced by the hydrolytic weathering of aluminous sediments and then gibbsite was formed as early kaolin was desilicated.
