Inequities in access to mental health care at intersections of race/ethnicity, gender identity, and gender modality: An application of Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA)
… with the novel Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) method to assess the prevalence of unmet mental healthcare needs at critical intersections of gender modality, gender identity, and race/ethnicity. Participants were 699,843 U.S. adults …

An Economic Analysis of Secure Messaging between Patients and Providers
… misspecifications and accounts for individual unobserved heterogeneity. Controlling for individual characteristics such as age, gender, insurance source, health status, and individual unobserved heterogeneity (fixed effects), we found that an increase by $1 in the price of office …

Quantile Regression for Panel Data
… Gaussian random effects model to account for individual heterogeneity, but this approach precludes estimating effects other than the mean. To get around the problem, we employ the quantile regression panel methods. The analysis shows that the program impact is largest in the lower tail of the …

Do job-seekers benefit from contacts? : a direct test
… test proposed by Mouw (2003). By using a within-individual fixed-effects methodology, the direct test rules out most sources of between-individual heterogeneity (Yakubovich 2005). Therefore, its results are not influenced by the quality of the measures used to assess a job-seeker's social …

Identification and estimation in panel models with overspecified number of groups
… groups into further subgroups, but cannot mix individuals from different groups. When the true number of groups is used in estimation, all the individuals can be categorized correctly with probability approaching one, and we establish the limiting distribution for the estimates of the group …

Agricultural change and farmworker living standards in post-apartheid South Africa
… in the post-apartheid period. Using a panel of individuals and in so doing, controlling for unobserved individual heterogeneity and initial household fixed effects, a difference in differences approach is used to estimate the impacts of migration on various measures of individual living …

Estimating population density and survival of ocelots in six study sites over multiple years in Belize, Central America
… estimated densities ranging from 6.4 - 22.5 individuals/100km2 in the broadleaf forested sites. Robust design models estimated densities from 8.8 - 22.8 individuals/100 km2 and ocelots had high annual survival (71-79%) in 2 broadleaf sites. Contrary to predictions, robust design models had …

Population ecology of wood ducks in Nevada under experimental manipulation of harvest
… Additionally, I assessed how variation among individuals affects the mortality and recruitment processes. Harvest regulations are used to minimize detrimental effects of hunting on wild populations. In the second chapter I used capture-mark-reencounter data, from wood ducks that live along the …

A Study of Actuarial Models for Insurance Based Applications
… on personal characteristics of working age individuals such as disability, educational attainment and the current employment state. Applied to UK longitudinal Labour Force Survey data, it quantifies the disadvantages that plaintiffs with post-injury earnings capacity face in the labour …

Human Cellular Genetics of Innate Immunity
… variability in this signalling pathway between individuals, alongside cell-to-cell heterogeneity in a genetically identical cell population, the basis of this variation is not fully understood. In this PhD, I established large-scale single-cell RNA sequencing experiments to study cellular …

Causes and consequences of pair-bond disruption in socially monogamous species
… investigates the effect of global changes and individual heterogeneity on pair-bond disruption (divorce or widowhood) and their consequences for vital rates and life-history outcomes for socially monogamous species. In Chapter 2 and Chapter 4, analyses of long-term demographicdatasets reveal …

Bridging the gap between populations and individuals in the philosophy of medicine
… the relationship between populations and individuals in the philosophy of medicine. There is a long-standing tension in the fact that randomised, controlled trials in clinical populations count among the best evidence in medicine, while the goal of medical practice is to help individual …

Influence of network structure on disease spread and persistence
… a central role in the spread of disease between individuals, and networks offer a convenient representation of contact patterns. This thesis explores the effects of network structure on transmission dynamics using two diseases as case studies: African swine fever (ASF), a fast-spreading viral …

Natural Killer Cell Responses to Human Cytomegalovirus

Essays on Behavioral Economics and Sophisticated Procrastination
… by strategic trade-offs, self-awareness, and individual heterogeneity. The first essay develops a theoretical model of Perfectionistic Procrastination, proposing that individuals with high internal standards may delay tasks not as a simple lapse in self-control, but as a strategic response to …

Housing price dynamics and household mobility decisions

Essays on the dynamics of qualitative aspects of firms' behavior
… show that observable characteristics of the individual firms are important in understanding the dynamics of firm's attrition. Cyclical effects and macroeconomic variables have also a strong impact on bankruptcies, liquidations and reorganizations. Unobserved firm heterogeneity, modeled by …

Studying coupled human and natural systems from a decentralized perspective: the case of agent-based and decentralized modeling
… interactions, we studied the role of individuals in a coupled agricultural and hydrologic system. The model was designed to simulate the interactions between farmers pumping groundwater to irrigate their corn fields and the water levels within a portion of the aquifer below the …

Three essays in labor economics
… We then use the model's characterization of individual heterogeneity to identify the effects of youth idleness on employment and earnings when young men are in their early thirties. We find that idleness reduces employment and earnings for such men in their early 30's. We estimate that an …
