Multi-parametric numerical simulation of age-specific cancer rates in human populations
… to analyze epidemiologic data describing the age-specific risk of cancer in terms of hypotheses about historical environmental risks, the heritability of cancer, the role of gender and the processes embedded in cancer formation. The program was based on the theories of Professor W. Thilly …

Age-specific mortality, pre- to post-fledging carryover effects, and the timing of fledging in altricial songbirds
… accumulated over recent decades has implicated age-specific mortality as a critical factor shaping life histories, particularly with respect to the mortality of dependent offspring. Altricial songbirds provide a practical system to examine associations among variation in life histories and …

Towards an understanding of the developmental zebrafish (Danio rerio) proteome and impacts of age-specific sensitivities with a model toxicant.
… among future studies. Early life stage zebrafish have gained popularity as an animal alternative with incorporation into standardized methods (such as Organisation for Economic Cooperation and Development test guideline no. 236) to become arguably the most important alternative …

A Multidimensional Investigation of Sexuality in Older Adults Within a Successful Aging Model
… has traditionally been evaluated in relation to age-related physical limitations and sexual dysfunction. This study developed a multidimensional model of sexual well-being by investigating sexual interest, sexual attitudes (general and age-specific), and age-specific sexual knowledge in relation …

Simulation and sensitivity analysis of the choice of open interval, the methods of open interval, the methods of estimating life expectancy, completeness and 6 in the SEG method of estimating mortality
… of the SEG method corrects for differential coverage of censuses directly by adding a constant (6) to the age-specific growth rates such that the correction leads to a horizontal series of age specific estimates of completeness. This research attempts to obtain the best variation of this version …

Essays On Aging-Related Disease In The U.s. Population
… In the first essay, I investigate changes in age-specific diabetes prevalence across cohorts born in the 20th century and use the cross-cohort comparisons to generate model age patterns of diabetes prevalence and incidence. I show that most of the increase in diabetes prevalence over time is …

Nervous system cancer : analysis of historical mortality rates in the United States and Japan indicate sudden increases in environmental risk
Nervous System cancer age-specific mortality rates began being recorded for European and Non-European Americans in 1930 and for Japanese in 1952. All ethnic groups show significant historical increases in mortality rates. For the two American data sets, the age- specific pattern for mortality seems …

ESTIMATING GIRAFFE (GIRAFFA CAMELOPARDALIS) POPULATION SIZE AND SURVIVAL RATES IN SOUTH LUANGWA VALLEY, ZAMBIA
… of demographic parameters such as sex- and age-specific survival rates. I addressed those research needs for a geographically-isolated population of giraffes (<em>Giraffa camelopardalis</em>) in South Luangwa Valley, Zambia. During 2016 to 2018, collaborators opportunistically photographed …

Contraception and HIV-1 prevention among women in Africa: informing choices amid expanding options
… and HIV-1 prevention with the following specific aims: (1) evaluate the association between the increasingly-available copper intrauterine device (Cu-IUD) and a potential side effect, bacterial vaginosis (BV), and assess whether the association varies over time; (2.1) determine the …

Demography of the spotted turtle (clemmys guttata) in Illinois
… and reproductive data spanning 1988–2016 and Package RMark to analyze deterministic measures of change for both populations. Both populations exhibited an even sex ratio, a strong bias towards adults, and positive growth over the length of the study. I used a POPAN model to estimate the population …

Gender-specific epidemiology of tuberculosis in a population with high HIV prevalence
… Town is primarily due to HIV infection in this age group. During 2009, City of Cape Town TB clinics prospectively collected routine notification data on 29,478 new TB cases. The objectives of this analysis were to describe the 2009 Cape Town TB case population by gender, age, and HIV; explore …

Age-related Differences in Patient Outcomes and Factors Associated with Psychiatric Stays at the Dube Centre, Royal University Hospital, Saskatoon
… exponential increase in life expectancy, the average 65-year-old Canadian can expect to live for an additional 21 years. This increase in the population of seniors will significantly impact the healthcare system and though mental health conditions occur throughout life course, seniors with mental …

A matter of evolutionary life and death: an ecological model of growth and development in Homo erectus
… approach, it examines the related factors of age-specific mortality, encephalisation, and the rate and energetic burden of growth, in order to identify the mechanism by which H. erectus adapted to a diverse range of climates and environments, and how thoroughly that adaptation was achieved. An …

Detection probabilities and local population demographics of fishes in urbanized and forested streams of the New River basin, Virginia
… of stream fishes, and used estimates of size/age-specific detection probabilities to reduce bias in estimates of the reproductive success of various fish species in urban and forested stream habitats. In Chapter 1, I examined differences in detection probabilities of stream fishes among …

Non-proteolytic roles of the ubiquitin-proteasome system in memory formation across the lifespan
… by complex molecular mechanisms and region-specific changes in the brain. Epigenetic modifications, such as histone monoubiquitination and ubiquitin signaling, have emerged as key players in these processes. While monoubiquitination of histone H2B is a well-established regulator of increased …

Coastal zone utilization by juvenile fish in the Eastern Cape, South Africa
Many coastal fish exhibit age-specific differential distribution and shallow inshore regiong provide nursery habitats for juveniles of some species. In this study the occurrence of juvenile fish along the Eastern Cape coast was examined with the objective of assessing the importance of coastal …
