Background

In industrialized populations, low male testosterone is associated with higher rates of cardiovascular mortality. However, coronary risk factors like obesity impact both testosterone and cardiovascular outcomes. Here, we assess the role of endogenous testosterone on coronary artery calcium in an active subsistence population with relatively low testosterone levels, low cardiovascular risk and low coronary artery calcium scores.

Methodology

In this cross-sectional community-based study, 719 Tsimane forager-horticulturalists in the Bolivian Amazon aged 40+ years underwent computed tomography (49.8% male, mean age 57.6 years).

Results

Coronary artery calcium levels were low; 84.5% had no coronary artery calcium. Zero-inflated negative binomial models …

Biopsychosocial Resilience Through A Complex Adaptive Systems Lens: A Narrative Review Of Nonlinear Modeling Approaches, Adam W. Kiefer, David Pincus

Psychology Faculty Articles and Research

Human resilience is often considered as static traits using a reductionist approach. More recent work has demonstrated it to be a dynamic and emergent property of complex systems. This narrative review explores human resilience through a self-organizing framework with a specific emphasis on the application of nonlinear modeling approaches. Four classes of approaches are examined: univariate dynamics, bivariate coupling, topological modeling, and network modeling. Univariate dynamics capture the temporal structure and flexibility within a single time series, while bivariate coupling approaches quantify the interaction dynamics and coordination between two time series. Topological modeling identifies bifurcations and attractor dynamics as signals …

Across multiancestry groups, we analyzed Human Leukocyte Antigen (HLA) associations in over 176,000 individuals with Parkinson’s disease (PD) and Alzheimer’s disease (AD) versus controls. We demonstrate that the two diseases share the same protective association at the HLA locus. HLA-specific fine-mapping showed that hierarchical protective effects of HLA-DRB1*04 subtypes best accounted for the association, strongest with HLA-DRB1*04:04 and HLA-DRB1*04:07, and intermediary with HLA-DRB1*04:01 and HLA-DRB1*04:03. The same signal was associated with decreased neurofibrillary tangles in postmortem brains and was associated with reduced tau levels in cerebrospinal fluid and to a lower extent with increased Aβ42. …

Ten Questions Concerning Smart And Healthy Built Environments For Older Adults, Sanjay Kumar, Samuel H. Underwood, Julie L. Masters, Natalie A. Manley, Iason Konstantzos, Josephine Lau, Ryan Haller, Lily M. Wang

Durham School of Architectural Engineering and Construction: Faculty Publications

In the past decade, the term ‘global aging’ has gained much attention among researchers, policymakers, civil societies, and governments worldwide. The continuous decline in fertility rates and increased life expectancy have resulted in an ongoing demographic transition where the share of adults aged 65 or older is increasing and outnumbering children younger than five years. In the United States and other developed countries, this rapid demographic transition is expected to continue to strain the existing health infrastructure as it becomes increasingly challenging to ensure healthy living environments for older adults. The ten questions and answers in this paper have been …

Utilizing New Technologies To Measure Therapy Effectiveness For Mental And Physical Health, Jonathan Ossie

Dissertations

Mental health is quickly becoming a major policy concern, with recent data reporting increasing and disproportionately worse mental health outcomes, including anxiety, depression, increased substance abuse, and elevated suicidal ideation. One specific population that is especially high risk for these issues is the military community because military conflict, deployment stressors, and combat exposure contribute to the risk of mental health problems.

Although several pharmacological approaches have been employed to combat this epidemic, their efficacy is mixed at best, which has led to novel nonpharmacological approaches. One such approach is Operation Surf, a nonprofit that provides nature-based programs advocating the restorative …

The Development Of A Dance/Movement Therapy Method For Social Engagement With Adolescents In A Partial Hospital Program, Kayleah Pensalfini

Expressive Therapies Capstone Theses

Mental health can significantly impede navigating the social domain during adolescence. Research has indicated social development of adolescents may be impacted by psychopathology and emotional development, further hindering one’s formation of self. There is also limited research showing the effectiveness of Dance/Movement Therapy (DMT) with the adolescent population. This writer designed and adapted one DMT session for adolescents to understand this topic better. This capstone will present an adaptable method utilizing a DMT intervention with participants between the ages of 13-17 in a Partial Hospital Program (PHP). This project aimed to examine how DMT can support self-identity and the acquisition …

Dance/ Movement Therapy As A Primary Therapeutic Intervention To Improve Social And Communication Skills Of Children With Autism Spectrum Disorder: A Literature Review, Allyssa Millar

Expressive Therapies Capstone Theses

This literature review examines dance movement therapy as an intervention to help children with autism spectrum disorder strengthen social and communication skills. Social barriers due to autism include taking turns, making decisions, participating in joint attention, recognizing emotions in others, and recognizing social cues. Communication skills in children with autism can vary from being unable to verbally express wants and needs to only utilizing gestures to communicate. Dance movement therapy uses the strengths of the children to help develop a communication system that can be understood by those around them. Research studies help to show that use of dance movement …

Human Diversity In Molecular Sexual Dimorphism And Gender Disparities In Health, Adam Z. Reynolds

Anthropology ETDs

Although males and females exhibit an extraordinary range of diversity in sexual dimorphism across populations, prior work on the evolution of sexual dimorphism in human physiology and health has focused on ostensibly universal differences that owe to sex chromosomes and steroid hormones. This dissertation argues that sexual dimorphism in humans is not adequately captured by species-wide sex differences in mean trait values, but instead varies greatly as a result of: (i) our ability to adapt physiologically to a broad range of social and physical environments, and (ii) molecular diversity acquired by different populations over the course of their unique evolutionary …

Fatty Females And Muscular Males: Investigating Human Sexual Dimorphism Across The Upper And Lower Skeleton, Brooklin Edwards

Anthropology Undergraduate Honors Theses

The sexual dimorphism profile of human body composition produces a unique pattern. Compared to other primates, humans have a mild size dimorphism; however, human males have a particularly muscular upper body and human females have a permanent fatty composition. These findings have resulted in varying interpretations related to sexual selection, mating systems, and male competition. Using humerus and femur measurements collected from 9 primate species, we investigated how the pronounced sexually dimorphic tissue composition of humans influences skeletal elements compared to the other primates. We hypothesized that over the course of human evolution, human females developed a body composition that …

Small Unmanned Aircraft Systems: Operator Workload And Situation Awareness Utilizing First Person View Techniques, Ross Lucas Stephenson Jr

Doctoral Dissertations and Master's Theses

The small, unmanned aircraft systems (sUAS) sector within the aviation industry is experiencing unprecedented growth. However, the regulatory guidance for the safe integration of sUAS into the National Airspace System (NAS) has not kept pace with this technological growth within the market. Current regulatory limitations of line-of-sight operations may have an impact on the establishment of an equivalent level of safety for sUAS operations as maintained by manned aircraft. The focal point of the discussion of line-of-sight operations has been the ability of the sUAS pilot to see and avoid all obstacles and other aircraft in a safe and timely …

Highway To The Comfort Zone: History Of The Psychrometric Chart, Eric Teitelbaum, Clayton Miller, Forrest Meggers

Research Collection College of Integrative Studies

The psychrometric chart is the most common data visualization technique for the designers of thermal comfort systems worldwide. From its humble roots as means of expressing the characteristics of air in building systems design, the use of the chart has grown to include the representation of the zones of human thermal comfort according to both conventional and adaptive models. In this paper, we present an extensive history of this development and the fallacies with representing comfort simply as a box that sometimes moves on the chart. The origins of the link between refrigeration control and comfort control are examined through …

Immune System Dysfunction To Toxicant Exposure: An Examination Of Mismatch Theory With Polychlorinated Biphenyls (Pcbs) And Dichlorodiphenyltrichloroethane (P,P'-Ddt), Florence Lee

Legacy Theses & Dissertations (2009 - 2024)

Exposure to environmental contaminants, including persistent organic pollutants (POPs) can disrupt normal immune function. As POPs, polychlorinated biphenyls (PCBs), dichlorodiphenyldichloroethane (p,p’-DDE, a metabolite of p,p’-DDT), and hexachlorobenzene (HCB) are synthetic chemicals with long half-lives and can bioaccumulate and biomagnify within organisms throughout the food chain. This dissertation proposes that pollutant exposure can affect the immune system based on a sample of Native American women, thereby influencing human biological variation, and the development of an autoimmune phenotype. Data was collected from a sample of Native American women utilizing anthropometric measurements, medical diagnoses of autoimmune disease, autoimmune dysfunction symptoms, and serum samples. …

Reflections On A Career Unplanned, Robert A. Glazer

Gulf and Caribbean Research

Sometimes life takes unexpected turns. I never planned to be a marine biologist; yet, after a long and unpredictable journey, that’s exactly where I found myself. After obtaining my B.S. in Fishery Biology from Colorado State University, I found myself meandering from job to job like a golden retriever following some vague scent. At first, I was hired by the Wyoming Game and Fish Department to work seasonally in Grand Teton National Park on the freshwater trout fisheries. Soon thereafter, I found myself cultivating oysters, clams, and other shellfish in California. The skills I developed there as an algologist led …

Salivary cortisol levels served as indicators of stress, while social skills were evaluated using the parent-report Social Skills …

Reduced Serum Concentrations Of Reactive Oxygen And Nitrogen Species Following Strenuous Exercise In The Heat Are Not Associ-Ated With An Upregulation In Serum Antioxidative Capacity, Sebastian Keller, Hannah Lisa Notbohm, Wilhelm Bloch, Moritz Schumann

Baltic Journal of Health and Physical Activity

Introduction: Reactive oxygen and nitrogen species (RONS) are produced as a response to exercise and play a part in guiding the adaptive response to physical training. Exercise in the heat has been shown to further increase accumulation of RONS in systemic circulation; however, a high antioxidative response or heat acclimatization mechanisms could attenuate this response. In a previous study, we found reduced RONS concentrations in trained athletes following strenuous cycling in the heat. Therefore, this secondary analysis assessed whether these reduced RONS serum concentrations are induced by an increased serum antioxidant capacity. Methods: Twelve male cyclists (V̇O_2peak: 60 …

Color, Culture, And The Implications For Emotional, Cognitive, And Behavioral Reactions, Renee Lucas

LSU Master's Theses

Color plays a significant role in life, influencing how we perceive things, how symbols change in meaning, how brands, logos, and pictograms are communicated, as well as how our emotions are perceived and how our moods are affected. For designers, advertisers, and visual communicators, color is crucial because it has a big impact on how people perceive, relate to, and value an image or advertisement. There are many factors that play a role when people develop their personal color interpretations – one being culture. The purpose of this study is to investigate the links between culture, color, and individuals’ cognitive, …

Role Of Dim Artificial Light At Night (Dalan) On Body Weight Percentage Increase Of Mus Musculus, Stephanie A. Babinec

Journal of the South Carolina Academy of Science

Light pollution at night is a growing issue in many suburban and urban settings, commonly referred to as artificial light at night (ALAN). Many studies have been conducted as to how the intensity or wavelength of this lighting can disrupt the circadian rhythm but none have evaluated how the timing of this light could affect it. It is hypothesized that those that chronically experience dim artificial light at night (dALAN) after biological day will lead to a more pronounced disruption in the metabolic system and therefore will cause an increased level of weight gain. Mice were used as test subjects …

In Chapter 1, I aim to introduce msTBI and two known sequelae of neurovascular damage in msTBI: reduced cerebral blood flow (Ware et al., 2020; Julliene et al., 2016) and altered low frequency fluctuations in blood oxygen level-dependent signal (Zhou et al., 2021; Palacios et al., 2013). Chapter 2 aims to identify the regional pattern of altered resting cerebral blood flow from a cohort of 29 patients with msTBI assessed at 3, …

Building Nature: A Nature-Based Drama Therapy Method In An Urban Program, Courtney Bennett Mcduffee

Expressive Therapies Capstone Theses

Finding a mental health center that fits the needs of an individual can take time. Some individuals must travel to different states and enter large metropolises to find the specific type of support they need for their mental health journey. This can mean that for extended periods of time, as individuals go through residential treatment, partial hospitalization programs (PHP), and/or intensive outpatient programs (IOP), they can not only find themselves in a completely new community, but also entirely removed from nature. For this reason, my thesis focused on creating a method to reconnect humans ‘trapped’ in an urban setting with …
