The Limits Of Healthy Habits: Exploring The Relationship Between Disordered Eating, Body Image, Mindfulness, Social Media, And Dysfunctional Exercise, Taylor A. Dinkel

Master's Theses

In recent decades, there has been an increase not only in full syndrome eating disorders, but also in subclinical presentations of disordered eating, many of which include dysfunctional relationships with exercise. Although not full diagnosable syndromes, disordered relationships with food and exercise, as well as a preoccupation with body image, can cause severe physical and psychological stress for individuals who present with these dysfunctional patterns. With the growth of fitness-related social media accounts, the increase in social media usage during the pandemic, and the increase in subclinical disordered eating presentations and dysfunctional relationships with exercise, it is important be aware …

Age, Growth, And Simulation Modeling To Characterize Fish Populations At Two Reservoirs In South-Central Kansas, Brian Serpan

Master's Theses

Several fish populations in Kansas are heavily exploited. To obtain insight into the response of fish populations to management actions, fisheries biologists must obtain as much information as possible with limited resources. To address these challenges, biologists often use age and growth information to understand the age structure of the populations, estimate recruitment and mortality, and gain insight into environmental and genetic factors influencing growth. In addition, age and growth data are used to generate yield-per-recruit models, which allow biologists to extrapolate population trends and make broad predictions about population responses to different management actions.

The Effectiveness Of Glare-Obscuring Glasses On Nighttime Driving Performance, Heath Theodore Friedland

Master's Theses

Currently no driver-aid system effectively addresses glare-reduction for oncoming headlights. Glare at night has the ability to decrease our visual acuity and cause discomfort or pain. This decreased visual ability constitutes an increased risk for driver error and a potential roadway safety hazard. The severity of these detrimental effects has previously been shown to increase with driver age and is thought to be further exacerbated by the increased brightness of High Intensity Discharge (HID) headlights.

In the current study, the effects of headlight glare from HID and halogen lights on driver performance was examined in a custom driving simulator. A …

In Vivo Measurement Of Color Relationships Between The Maxillary Central Incisor And Canine As A Function Of Age, Marie E. Falcone

Master's Theses

Abstract

Introduction

It has long been taught that the basic shade (hue) of the patient can be taken from the canine (i.e. that tooth thought to have the highest chroma of a particular hue) and then that hue can be applied to other anterior teeth but at a lower chroma. However, this concept does not appear to derive from published measurements or observations. This study documented the color relationship between in vivo maxillary central incisors and canines to examine: (1) whether they share the same hue, but have different chromas (as commonly taught); and, (2) whether color differences (∆E values) …

Ischemia Impairs Vasodilation In Skeletal Muscle Resistance Artery, Kyle Remington Struthers

Master's Theses

Functional vasodilation in arterioles is impaired with chronic ischemia. We sought to examine the impact of chronic ischemia and age on skeletal muscle resistance artery function. To examine the impact of chronic ischemia, the femoral artery was resected from young (2-3mo) and adult (6-7mo) mice and the profunda femoris artery diameter was measured at rest and following gracilis muscle contraction 14 days later using intravital microscopy. Functional vasodilation was significantly impaired in ischemic mice (14.4±4.6% vs. 137.8±14.3%, p<0.0001 n=8) and non-ischemic adult mice (103.0±9.4% vs. 137.8±14.3%, p=0.05 n=10). In order to analyze the cellular mechanisms of the impairment, a protocol was developed to apply pharmacological agents to the experimental preparation while maintaining tissue homeostasis. Endothelial and smooth muscle dependent vasodilation were impaired with ischemia, 39.6 ± 13.6% vs. 80.5 ± 11.4% and 43.0 ± 11.7% vs. 85.1 ± 10.5%, respectively. From this data, it can be supported that smooth muscle dysfunction is the reason for the observed impairment in arterial vasodilation.

Life History Characteristics Of The Starry Skate, Raja Stellulata, From California Waters, Kelsey James

Master's Theses

The order Rajiformes, or skates, is a morphologically conservative group that exhibits a wide range of life history characteristics. This inter-species variability warrants species-specific research. This study investigates the age, growth, reproduction, and habitat of the Starry Skate, Raja stellulata, which is endemic to the U.S. West Coast. Age and growth parameters were determined using two preparation techniques: gross sectioning and histological sectioning. The assumption that gross sections deposit one band pair a year was indirectly validated with centrum edge analysis and marginal increment ratio. It was not indirectly validated with histological sections. Age estimates from gross sections ranged from …

Do We Know What We Know? Self- Assessment Across The Lifespan, Courtney Clare Lee

Master's Theses

Self-knowledge can play a critical role in navigating physical, cognitive, and social changes in late life. To protect and preserve one's sense of self against these changes, individuals may engage in self-enhancing and self-serving biases in areas important to self-esteem. The importance attached to these areas may change with age, and self-knowledge of these psychological processes may vary with age. We investigated self-enhancing biases and metacognitive awareness of abilities in adulthood. Participants ranging in age from 20 to 80 completed a series of tests assessing the better than average effect across a variety of age-relevant domains as well as objective …

Age And Sex Differences, Meaningfulness And Formal Similarity In A Verbal Discrimination Task, Aleen Burke Dempster

Master's Theses

The present investigation is concerned with learning in the aged. The task is a verbal discrimination one, in which the dimensions of meaningfulness and formal intrapair similarity are examined. The study is ontogenetic in the limited sense that the older sample, over 60 years of age, is compared to a sample of college age youth.
