Assessing the Global Threat of Coastal Flooding: A Mortality Risk Model
… growing threat. Previous studies have documented mortality associated with historical coastal flooding and developed predictions of mortality risk based on SLR and human development. This study updates those estimates and provides a new model by including new mortality data from events between …

Development of a mortality risk prediction score for patients with AML requiring critical care
… with acute myeloid leukemia (AML) have high mortality after intensive care unit (ICU) admission, long-term survival is possible. There is no accepted model for predicting longer-term mortality after ICU admission. We examined the role of five AML and ICU related risk factors in mortality …

Retirement income, bequests, and insurance : implications of mortality risk in a stochastic life cycle model
… model of consumption, extended to account for mortality uncertainty. Chapter 1 empirically examines household decisions about whether or not to annuitize balances 111 defined contribution pension plans upon retirement. This study calculates a utility based measure of annuity valuation for …

Mortality Risk Among Patients Who Present to Hospitals with Out-Of-Hospital Cardiac Arrest and ST-Elevation Myocardial Infarction
… tool that can identify patients with a very high mortality risk upon hospital presentation may inform decision-making regarding emergent procedures. Within the Cardiac Arrest Registry to Enhance Survival (CARES), I included adult patients with OHCA and STEMI who presented from January 2013 to …

Resource Selection, Survival, and Departure of Adult Female Mallards From The Lake St. Clair Region During Autumn And Winter
… their spatiotemporal distribution to avoid mortality risks while balancing trade-offs to access foods to undergo migration and maintain homeostasis. Thousands of mallards use Lake St. Clair as it is an important, but threatened, migratory staging area in the Great Lakes. My goal was to …

Racial/Ethnic and Rural Differences in Alcohol Use, Care, and Related Outcomes among VA Patients Living with HIV
Alcohol use is common and particularly risky for people living with HIV (PLWH). Certain subpopulations of PLWH, such as racial/ethnic minorities and rural PLWH, may be at particularly increased risk of adverse alcohol-related outcomes. This dissertation describes differences in alcohol-related …

Cardiorespiratory Fitness as a Clinically Relevant Risk Factor
… whether there is a difference in all-cause mortality risk between CRF achieved through physical activity (PA) (active; CRF-A) compared to the same CRF achieved without (inactive; CRF-I). The main finding of this study was that while both CRF-A and CRF-I were associated with lower all-cause …

Modelling mortality heterogeneity using health trajectories and multimorbidity
Mortality heterogeneity is a generally well understood area of longevity risk that remains relatively unexplored in the actuarial pricing of longevity linked products. However, with increasing amounts of longitudinal individual level data, there exists an extraordinary opportunity to derive more …

How Do Immigrant Older Adults in the United States Fare in Later Life? Examining Differences in Immigrant Status and Life-course Timing of Migration on Late-life Disablement and Mortality
… 1) To determine if the immigrant health and mortality advantage extends to late-life disablement, 2) To examine how life-course timing of migration affects late-life disablement for immigrants. Results from Markov transition models show that compared to non-immigrant older adults, immigrants …

Sex-Based Differences in Mortality and Metabolic Disease in Subadult Skeletal Assemblages of Tell Hisban
Heterogeneity in morbidity and mortality risk results from various underlying host-level and societal factors. Identifying these risk factors in ancient communities is often hindered by the invisibility of some variables in the archaeological record and the methodological limitations of skeletal …

A cohort perspective of U.S. adult mortality
… racial and educational disparities in U.S. adult mortality. The project is organized around three themes. First, I emphasize that recent temporal changes in U.S. adult mortality risk are rooted in cohort forces. Unfortunately, much of the mortality literature has failed to account for the fact …

Factors Affecting Natal Dispersal by Song Wrens (Cyphorhinus Phaeocephalus): Ecological Constraints and Demography
… hypothesis, however. I then estimated dispersal mortality risk for male and female Song Wrens. My estimates revealed that males and females may suffer very different costs of dispersal. While such risks have often been proposed as important in the evolution of dispersal patterns, dispersal …

Body Weight and Mortality Among Adults Who Never Smoked
<p>Most prospective studies identify an increased mortality risk for adults of high body mass index (> 27 kg/m<sup>2</sup>) that is commonly attributed to the effects of excess body fat, and also identify an increased mortality risk for adults of low body mass index (< 21 kg/m<sup>2</sup>), an …

Predicting pulmonary hypertension and outcomes in patients with left heart disease
… is almost invariably associated with increased mortality risk, but the effects on hospitalization are yet to be fully characterized. All groups of PH are found in SSA with LHD being the major cause. PH-LHD affects young people and is predominantly due to HF and rheumatic valvular heart disease. …

Birth spacing and child mortality in Mozambique : evidence from two demographic and health surveys
This research examines child mortality risk associated with short preceding birth intervals in Mozambique in quinquennial periods between 1978 to 1998 using data from the 1997 and 2003 DHS. A log rate model for piecewise constant rates is applied. The piecewise hazard function assumes a constant …

Forest Mortality in Lake Tahoe Basin from 1985-2010: Influences of Forest Type, Stand Density, Topography and Climate
Widespread and synchronous outbreaks of forest mortality during the 1990s and continuing to present day have drastically altered millions of hectares of forestlands from Mexico to Alaska (Bentz 2009). Tree mortality is a complex process with a variety of both exogenous and endogenous factors …
