Aging Is a Determinant in Anoxia Stress Tolerance in Caenorhabditis Elegans

Description: Oxygen availability is critical for survival for most organisms. The nematode, C. elegans, has been useful for studying genetic regulation of anoxia tolerance due to the oxygen deprivation response mechanisms shared with other metazoans. Studies examining long-term anoxia (72h, LTA) tolerance have only been conducted at adult day 1. To investigate the effect of aging on anoxia tolerance wild-type and mutant strains were exposed to LTA between adult day 1 and day 9. Wild-type isolates and daf-16… more

The Willingness of Older Adults to Evacuate in the Event of a Disaster

Description: The issue of rising number of disasters, the overwhelming increase in number of older adults, and historically flawed evacuations presents real challenges. Disasters can strike anywhere, any time, and have devastating consequences. Since 1900, the number of Americans 65 and older has increased 12 times (from 3.1 million to 36.3 million). During the next two decades, the number of American baby boomers, now aged 45-64, who turn 65, will increase by 40%. As evidenced by recent disasters, the impe… more

Thermomechanical Processing, Additive Manufacturing and Alloy Design of High Strength Mg Alloys

Description: The recent emphasis on magnesium alloys can be appreciated by following the research push from several agencies, universities and editorial efforts. With a density equal to two-thirds of Al and one-thirds of steel, Mg provides the best opportunity for lightweighting of metallic components. However, one key bottleneck restricting its insertion into industrial applications is low strength values. In this respect, Mg-Y-Nd alloys have been promising due to their ability to form strengthening precip… more

Caregiving in Later Life: A Contextual Approach to the Provision of Care

Description: Guided by the life course perspective, this study examined the frequency of caregiving provided by older adults to kin and non-kin. A telephone survey produced a random sample of adults 60 years of age and older, which was predominantly White, with higher income and education levels (n = 278). Bivariate and multivariate analyses tested the impact of demographic characteristics and other variables, conceptualized as physical, human, and social capital, on the frequency of caregiving.

Non-Poissonian statistics, aging and "blinking'" quantum dots.

Description: This dissertation addresses the delicate problem of aging in complex systems characterized by non-Poissonian statistics. With reference to a generic two-states system interacting with a bath it is shown that to properly describe the evolution of such a system within the formalism of the continuous time random walk (CTRW), it has to be taken into account that, if the system is prepared at time t=0 and the observation of the system starts at a later time ta>0, the distribution of the first s… more

Access to Health Care and Rates of Mortality and Utilization for the Elderly in Rural America

Description: The aging experience of men and women in rural America is different than that of their urban counterparts. In this study, I identified key disparities in access to health care, mortality, and utilization of health care that result from geographic location. Foundational theories are discussed to illustrate that disparities can originate from historical societal behaviors. Secondary data and literary reviews create a combined qualitative and quantitative approach to explore the rural/urban divide… more

Depression and Helplessness-Induced Cognitive Deficits Among the Aged

Description: To investigate the impact of helplessness-induction on cognitive performance in the aged, 66 community-residing elderly persons (X=72.5 years) were administered a word association task, disguised as a test of onterpersonal empathy, under a) response independent (RI), b) response dependent (RD) reinforcement, o c) control conditions. The subjects were categorized as either depressed or non-depressed. Three (treatments) by two (levels of depression) by two measurements (pre- vs. post-treatment) A… more

Extroversion and openness to experience were also tested as moderators of the relationship between engagement and cognition. Results showed that the relationship between engagement at Wave 1 and cognition at Wave 2 did not differ from the relationship between cognition at Wave 1 and engagement at Wave 2. Testing f… more

The Metabolic Physiology of Planarian Flatworms

Description: Using a high throughput closed respirometry method to measure oxygen consumption, I determined metabolic rates in asexual and sexual Schmidtea mediterranea and Girardia dorotocephala, as a function of temperature, taxon, stressors, reproductive mode, age, regeneration, and specific dynamic action. This study has shown that oxygen consumption can reliably be measured in planaria using optode closed respirometry, and also provided a reliable method for measuring wet mass in planaria, which has be… more
