Socioeconomic Status, Physical Inactivity, And Bmi In Transitional Urban China: Contextualizing The Theory Of Fundamental Causes, Jun Xu, Fang Gong, Wei Zhao

International Journal of Physical Activity and Health

Drawing insights from the theory of fundamental causes of disease, this study examined the relationships between socioeconomic status (SES) and selected risk factors in transitional urban China. Specifically, under China’s distinct institutional and sociocultural environment, we examined how contextualized SES (i.e., party membership, hukou status, housing ownership, and subjective social status) and conventional SES indicators (i.e., education, income, and occupation) were associated with physical inactivity and body mass index (BMI). Utilizing the urban subsample of the 2017 Chinese General Social Survey (CGSS), we found that individuals with higher education, income, Communist Party membership, and urban hukou status had lower risks …

Evolution Of Functional Diversity In Defensive Bacterial Toxins And Parasite Infection Strategy, Logan D. Moore

Theses and Dissertations

Insects and their natural enemies are engaged in a never-ending battle called the ‘co-evolutionary arms race.’ As a part of these contentious interactions, vulnerable insects evolve natural barriers that prevent successful attacks by their natural enemies. In response, natural enemies evolve strategies that overcome these barriers. Occasionally, microbial symbionts will also participate in these relationships by assisting their insect host in defense against natural enemies or by assisting the natural enemy in subduing its prey. Alternatively, microbial symbionts may become contenders themselves in the co-evolutionary arms race by becoming reproductive parasites of their hosts. To mediate successful outcomes in these …

The Impact Of Obesity On Reproductive Health And Metabolism In Reproductive-Age Females, Samantha B. Schon, Hannah E. Cabre, Leanne M. Redman

Clinical Research Faculty Publications

Obesity is a highly prevalent chronic disease that impacts >40% of reproductive-aged females. The pathophysiology of obesity is complex and can be understood simply as a chronic energy imbalance whereby caloric intake exceeds caloric expenditure with an energy surplus stored in adipose tissue. Obesity may be categorized into degrees of severity as well as different phenotypes on the basis of metabolic health and underlying pathophysiology. Obesity and excess adiposity have a significant impact on fertility and reproductive health, with direct effects on the hypothalamic-pituitary-ovarian axis, the ovary and oocyte, and the endometrium. There are significant adverse pregnancy outcomes related to …

Phylogenetic And Biogeographic Patterns Of Devonian Proetid Trilobites, Katherine Jane Jordan

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Ecological disruption events such as mass extinctions can result in the permanent alteration in clades and ecosystems. A pivotal time of change during the history of life on Earth can be seen in the Devonian Period. During this time, major transitions in marine and terrestrial system resulted in a different world at the end of the period in comparison to the beginning. One such group most heavily impacted were trilobites. Trilobites were reduced to one order by the end of the Devonian: Proetida. My dissertation focuses on phylogenetic, biogeographic, and paleocommunity patterns of this group, known as the last of …
