The Relationship Between Neuroticism, Self-Esteem, And Disordered Eating Attitudes: Examining The Health At Every Size Theory, Liana Cho

Masters Theses

Background. In the modern day treatment of overweight/obesity, conflicting recommendations regarding treatment have been released by the Academy of Nutrition and Dietetics (AND) and advocates of the Health at Every Size (HAES) movement. While the AND have indicated their support for self-monitoring practices, such as keeping a food diary or tracking calories, HAES advocates have claimed that these restrictive practices may result in increased disordered eating tendencies and poor self-esteem.

Subjects. The participants for this study included 410 students at Grand Valley State University. Almost 80% of participants were female, and just over 85% of participants identified as white. …

Fat Bias And Culture Shock: Psychosocial Adjustments In Post-Obesity Life, Scott Thomas Macpherson

Masters Theses

Obesity in the United States is unprecedented levels, affecting adults and children as well. As our society has become for sedentary since industrialization, the nation has become fatter. The escalating rate of obesity has had a negative effect on the health of millions of Americans. Health problems such as metabolic disorders and other comorbidities, for instance, hypertension, Type II diabetes, heart disease, weight related cancers etc., (Mozaffarian and Benjamin 2013). The collective cost of obesity is to the nation is staggering, weighing in at $270 billion a year, childhood obesity costs nearly $15 billion alone (Hammond and Levine 2010). This …

The Passive Effects Of Full-Gateway, In-Street Signs On Vehicular Speed, De'lon Dixon

Masters Theses

Reducing motorist’s speed when approaching crosswalks is an important goal in reducing the number of collision between motorist and pedestrian in crosswalks. The current study addresses this goal. The effect of gateway installation of in-street signs (one in-street sign installed between the two travel lanes in each direction and one on both edges of the roadway in each direction) on vehicle speed was evaluated on nine roads. The results demonstrated that the Gateway in-street sign treatment produced large speed reductions as vehicles approached the crosswalk and at the crosswalk. The average speed reduction was 3.8 mph at the crosswalk and …

The Effects Of Reward And Risk Level Associated With Speeded Actions: Evidence From Behavior And Electroencephalography, Xingjie Chen

Masters Theses

Choosing a course of action in our daily lives requires an accurate assessment of the associated risks as well as the potential rewards. The present two studies investigated the mechanism of how reward and risk level influence the motor decisions of speeded actions (Chapter 2) and its neural dynamics (Chapter 3) by focusing on the beta band (15-30 Hz) oscillation patterns reflected in the EEG signals. Participants performed a modified version of the Go-NoGo task, in which they earned reward points based on the speed and accuracy of response. On each trial, the reward points at stake (120 vs. 6) …

Life Course Effects Of Polyvictimization: Associations With Depression And Crime, Richard Carbonaro

Masters Theses

Exposure to multiple forms of victimization has been shown to have increasingly negative outcomes, but their unique trajectory-setting effects have been largely unexplored. Using a life course approach, this paper examines the trajectory-setting effects of childhood polyvictimization into early adulthood. I use a nationwide sample including 3,652 respondents after cleaning and preparation. Seemingly unrelated regressions were used to predict depression and criminal behavior in childhood and adulthood. Results suggest childhood polyvictimization sets children on a negative trajectory which grows increasingly worse through the life course. Researchers and interventions should take these trajectory-setting effects into account when attempting to aid polyvictims.

Influence Of Household Chaos On Associations Between Physiology And Behavior, Sarah Mccormick

Masters Theses

Internalizing behaviors, or behaviors related to behavioral inhibition and the tendency to withdraw from novelty or uncertainty, are stable over time. There is substantial evidence indicating the association between greater resting right lateralized frontal EEG alpha asymmetry and negative affect as well as internalizing behaviors (Coan & Allen, 2003; Henderson, Fox, & Rubin, 2001; Fox, 1991). Further, right frontal asymmetry has been shown to be a stable marker of the presence of psychosocial risk (e.g. child maltreatment; see Peltola, Bakermans-Kranenburg, Alink, Huffmeijer, Biro, & van IJzendoorn, 2014 for meta-analyses). However, little is known about the influences of the home and …

The Environmental Kuznets Curve Hypothesis As A Problematic: Beyond "Falsificationism", Paul Erb

Masters Theses

Halfway into its third decade, the debate surrounding the environmental Kuznets curve (EKC) hypothesis has stalled with political economists and socio-ecologists ascendant and modernization theorists scrambling to give their apparently moribund perspective new life. But beyond the rise and fall of the EKC, there remains a second-order question and decades of data: how do the theoretical perspectives of these contenders shape what their protagonists do and don't see? How have they mistaken episodes of "talking past each other" for genuine dialogue? Which perspective has had the biggest impact on the other’s way of thinking? A qualitative and quantitative analysis compares …

Impact Of Perceptual Speed Calming Curve Countermeasures On Drivers’ Anticipation & Mitigation Ability – A Driving Simulator Study, Krishna Valluru

Masters Theses

A potential factor for curve accidents are anticipatory skills. Horizontal curves have been recognized as a significant safety issue for many years. This study investigates the impact and effectiveness of three curve based perceptual speed calming countermeasures (advanced curve warning signs, chevron sign, and heads-up display(HUD) sign) on drivers’ hazard anticipation and mitigation behavior across both left and right-winding curves, and sharp (radius 200m) and flat (radius 500m) curves. Experimental results show that the speed and lateral control in the horizontal curves differed with respect to curve radii, direction, and the type of countermeasure presented. These differences in behavior are …

Searching For The Fulcrum: Can Accountable Care Organizations Lower Spending By Balancing Specialists-To-Primary Care Providers?, Vishal Shetty

Masters Theses

Background:

While value-based payment models emphasizing care coordination have been widely implemented to improve quality and lower expenditures, supporting empirical evidence is sparse. Our objective was to quantify the impact of specialist-to-primary care physician involvement within accountable care organization (ACO) and its association with lower spending.

Methods:

We conducted a retrospective cohort study of Medicare Shared Savings Program ACOs from 2012-2016 using publicly available data provided by the Centers for Medicare and Medicaid Services at the ACO level. We examined the association between the proportion of primary care services delivered by specialists versus other types of care providers and ACO …

Facebook Intensity Use Related To Gender Identity And Self-Esteem Among Female College Students, Li Zhang

Masters Theses

As a popular social media platform, Facebook has already become a vital part of college students’ social lives. The purpose of this study is to explore the relationships among Facebook use, gender identity and the level of self-esteem among young female college students (from age 18 to 23). Previous studies have argued that Facebook has the ability to enhance or reshape gender identity by providing control over online self-presentation. In addition, by using Facebook intensively and frequently, users gain popularity (a larger network of Facebook friends), which also increases users’ self-esteem and the feeling of being connected with others. In …

Evaluating The Efficacy Of Convolution Neural Networks In Age At Deat Estimation Using 3d Scans Of The Pubic Symphyseal Face, Melissa A. Brown

Masters Theses

The research presented assesses the utility of machine learning approaches, specifically convolutional neural networks (CNNs), to the estimation of age at death in adult decedents by analysis of the pubic symphyseal face of the os coxa rendered as a 3D image. Age at death estimation is an important duty of forensic anthropologists working in medico-legal contexts, as well as bioarcheological researchers. The purpose of this study is to evaluate the accuracy of a CNN relative to the performance of human observers using traditional methods of age estimation. To accomplish this, a CNN created for this project and expert anthropologists were …

A Parametric Analysis Of Choice Under Risk, David W. Sottile

Masters Theses

Accurate assessment of risk propensity is important because risky choices underlie a broad range of behavioral problems. The Balloon Analogue Risk Task (BART) is an assessment that measures propensity to engage in risky choice. While this is a useful assessment, the BART changes two variables that affect risky choice simultaneously, probability of an undesirable outcome and stake size, which cannot be separated within the context of the BART. The goal of this study was to evaluate the separate and combined effects of key factors that are likely to risky choice (Magnitude of payoff, probability of an undesirable outcome, and stake …

College Self-Funding Predicting Deviant Behaviors, Blake A. Darling

Masters Theses

This study examines the effects of the source of college funding on student participation in four deviant behaviors: monthly binge drinking, monthly marijuana use, illicit drug use, and academic cheating. Using secondary data from a self-reported online survey conducted at a midwestern University, competing hypotheses based in general strain theory and social bond theory, were tested. Logistic regression analyses of the four deviant behaviors suggest that the source of college funding has a very limited effect. Only in the cases of marijuana use and illicit drug use were significant relationships observed; where students whose funding came from their parents were …

Evaluation Of Generalized And Specific Token Reinforcement Using A Paired Stimulus Preference Assessment And Progressive Ratio Schedules, Haily K. Traxler

Masters Theses

Skinner (1953) stated that the effects of generalized conditioned reinforcers should maintain longer than specific conditioned reinforcers because their effects are not dependent on a particular motivating operation. Tokens easily model different levels of generality because tokens can be paired with one or more back-up reinforcers. In the current study, three types of tokens were assessed that could be exchanged for either salty snacks, food and drinks offered in a small marketplace, or money on a gift card. Token preferences were assessed using a Paired Stimulus preference assessment and a progressive ratio (PR) task. The results of the preference assessment …

Meet The Duggars: The Reproduction Of Gender Privilege In The Popular Construction Of Sibling Sexual Abuse, Jessica Reené West

Masters Theses

Sibling sexual abuse a nefarious harm that researchers suspect occurs for often than any other form of child sexual abuse, and is very rarely reported to authorities. On May 19th 2015, allegations of sexual abuse by Joshua Duggar against four of his younger sisters and a female babysitter during 2002 and 2003, were made public knowledge by the tabloid InTouch. In response to the public outcry, parents Jim Bob and Michelle Duggar sat for an interview on June 3rd 2015, in their family home with Fox News moderator Megyn Kelly. Statements made by The Duggars about sibling sexual abuse …

Application Of A Three-Lever Drug Discrimination Method To Differentiate The Interoceptive Stimulus Effects Of 3, 4-Methylenedioxypyrovalerone And 4-Methylmethcathinone In Male Sprague-Dawley Rats, Trent Bullock

Masters Theses

Psychoactive “bath salts” represent a continuing drug abuse problem. The synthetic cathinones, 3, 4-methylenedioxypyrovalerone (MDPV) and 4-methylmethcathinone (4-MMC) are popular constituents of “bath salts” in the United States and the United Kingdom, respectively. Addiction to these substances has proven difficult to treat, possibly requiring targeted therapeutics. Drug discrimination is a preclinical assay that may aid in treatment development. Thus far, two-lever (drug vs no drug) discrimination studies have exhibited asymmetrical substitution patterns between 4-MMC and MDPV. Therefore, a three-lever discrimination method was employed in which 12 male Sprague-Dawley rats were trained to discriminate 0.5 mg/kg MDPV, 2.0 mg/kg 4-MMC, and …

Contribution Of Monoaminergic Mechanisms To The Discriminative Stimulus Effects Of 3,4-Methylenedioxypyrovalerone (Mdpv) In Sprague-Dawley Rats, Harmony I. Risca

Masters Theses

3,4-Methylenedioxypyrovalerone (MDPV) is a popular synthetic cathinone reported to have a high abuse potential and comparable pharmacological actions to those of cocaine. The aim of this study was to evaluate a variety of monoaminergic agents for substitution, potentiation, or antagonism in rats trained to discriminate MDPV. Male Sprague-Dawley rats were trained to discriminate 0.5 mg/kg MDPV and a variety of monoaminergic drugs were tested for substitution and/or potentiation of the MDPV cue. In separate experiments, stimulus antagonism tests were conducted with selected dopamine antagonists or serotonin antagonists in rats trained to discriminate 1 mg/kg MDPV. Full substitution for MDPV was …

What Provides For Me As I Provide For Others? A Study Of Homeless Shelters Employees Within Kalamazoo, Michigan, Melanie Jezior

Masters Theses

Homeless shelters run on one thing: workers. Without workers there is no supportive aid for the homeless. A daunting and emotional job that is taken on by thousands, but why? Is the goal in entering this line of work to make an impact on homeless populations, a lasting difference? Everyone has their own personal reasons, however what are the main reasons for people going into a job like shelter work? What is it that motivates these workers to continue this line of work or motivates them to leave? It is a job that offers low pay, and emotional settings. A …

The Effects Of Gateway Width On Driver Yielding To Pedestrians: A Systematic And Parametric Analysis, Jonathan M. Hochmuth

Masters Theses

The gateway in-street sign treatment has been demonstrated to be a cost-effective method for increasing driver yielding behavior at crosswalks. In the present study, wide and narrow gateway widths were compared at two sites to determine if there was a differential effect on driver yielding behavior. Then, the relationship between width and yielding was refined with a parametric analysis at one of these sites. Gateway width was varied in two-foot intervals from 12ft to 18ft. The results indicated an inverse relationship between gateway width and driver yielding behavior. There are likely two variables related to this effect. First, because drivers …

A Study On Modelling Spatial-Temporal Human Mobility Patterns For Improving Personalized Weather Warning, Yue Xu

Masters Theses

Understanding human mobility patterns is important for severe weather warning since these patterns can help identify where people are in time and in space when flash floods, tornados, high winds and hurricanes are occurring or are predicted to occur. A GIS (Geographic Information Science) data model was proposed to describe the spatial-temporal human activity. Based on this model, a metric was designed to represent the spatial-temporal activity intensity of human mobility, and an index was generated to quantitatively describe the change in human activities. By analyzing high-resolution human mobility data, the paper verified that human daily mobility patterns could be …

Asian American Heritage Seeking: Personal Narrative Performances Of Ancestral Return, Porntip Israsena Twishime

Masters Theses

Asian American belongings, migration patterns, and transnational identities are largely constructed in the United States as static, unidirectional, and invisible. Asian Americans complicate these constructions through the practice of ancestral return. In this thesis, “ancestral return” is constituted through one’s participation in a university study abroad program to a specific place to where one traces her heritage. I use “return” not necessarily to account for a form of reverse migration; rather “return” here names the multiple, sometimes contradictory kinds of return, including “return” to a place that one has not yet been. This project examines how Asian American identities are …

"First Nations First": Understanding The Status Of Aboriginal Involvement In British Columbia's Community Forests, Sean O'Donnell

Masters Theses

In 2014, the legal landscape shifted in British Columbia with the unanimous Supreme Court decision, Tsilhqot’in Nation v. British Columbia. The case resulted in a recognition of Aboriginal title, and real and substantial Aboriginal authority over large tracts of land in the province. According to legal analysts, the most significant element is the requirement for stronger consultation with First Nations and – in many cases – consent that needs to be pursued by the province’s resource extraction industries prior to development. British Columbia’s community forest sector is unlikely to be immune to this shift. A baseline for First Nations involvement …

Alien Nation, Adam Hoole

Masters Theses

Can we (re)write our own subjectivity? What is lost in translation when we attempt to remake ourselves through speech acts? These questions are perhaps the most unsolvable and fundamental to inquiries into the operations of subjectivity. Nevertheless, they are questions I am to encounter and explore in this paper through a singular case study of the Manus Island Regional Processing Center. Founded in 2001, the Manus Island Processing Center served as a place for Australia to indefinitely detain refugees off-shore. The Processing Center was also a contentious site of violence and protest, of stillness and chaos, of love and despair. …

Strangers In A Strange Land: Foreign-Born Mangaka And The Future Of The ‘Japanese’ Comic Industry, Michele Fujii

Masters Theses

This thesis addresses the phenomenon of the recent success of foreign-born mangaka in the Japanese comic industry. One in a long line of foreigners who have written about Japan, Swedish mangaka Åsa Ekström is a representative example whose success has been facilitated by a set of circumstances brought on by the influence of the international manga market, socio-economic policies stemming from the unique challenges presented by Japan’s declining birthrate and rapidly aging population, and changes in the landscape of the Japanese publishing industry. Drawing upon themes and excerpts from Ekström’s popular comic essay series, Nordic Girl Åsa discovers the Mysteries …

Children's Self-Regulation During Reward Delay, Abigail Fontaine

Masters Theses

Individuals who display high levels of reward sensitivity are motivated by and respond to reward related cues, thus exhibiting more approach-motivated behaviors. A majority of the research on physiological indices of reward sensitivity in relation to self-regulatory abilities has focused on adults or adolescents, with relatively little work examining these associations in children. Thus, the current study sought to examine whether a common neural measure of reward sensitivity, left frontal electroencephalogram (EEG) asymmetry, assessed in early childhood was predictive of children’s later self-regulation abilities in the context of reward delay. Emerging inhibitory control skills were also examined as a potential …

Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, Brendan Abbott

Masters Theses

Depression and related disorders are characterized by motivational dysfunctions, including deficits in behavioral activation and exertion of effort. Animal models of relevance to depression represent a critical starting point in elucidating the neurobiological mechanisms underlying motivational dysfunctions. The present study explored the use of the Wistar-Kyoto (WKY) animal model of depression to examine effort-related functions as measured by voluntary wheel running and performance on a mixed fixed ratio 5/progressive ratio (FR5/PR) operant task. Given the known link between activational aspects of motivation and the mesocorticolimbic dopamine (DA) system, the behavioral effects of d-amphetamine (0.5 and 1.0 mg/kg, IP), a psychostimulant …

Peer Attention Modeling With Head Pose Trajectory Tracking Using Temporal Thermal Maps, Corey Michael Johnson

Masters Theses

Human head pose trajectories can represent a wealth of implicit information such as areas of attention, body language, potential future actions, and more. This signal is of high value for use in Human-Robot teams due to the implicit information encoded within it. Although team-based tasks require both explicit and implicit communication among peers, large team sizes, noisy environments, distance, and mission urgency can inhibit the frequency and quality of explicit communication. The goal for this thesis is to improve the capabilities of Human-Robot teams by making use of implicit communication. In support of this goal, the following hypotheses are investigated: …

"Only The Intervenor Cared": A Critical Juncture In The Rise Of Dairy Cafos And Neoliberal Environmental Policy In Wisconsin, Sarah Emily D'Onofrio

Masters Theses

Building on scholarship regarding the rise of neoliberalism since the late 1970s and using a comparative-historical methodology, this thesis examines a case study regarding how state governments in the United States have succumbed to neoliberal pressures over time. Specifically, this thesis examines the rapid expansion of concentrated animal feeding operations (CAFOs) in Wisconsin since 1995. As these large CAFOs have grown in size, so have the social and environmental problems related to their use, including pollution of drinking water sources for rural communities. Based on analysis of hundreds of newspaper articles, this thesis finds that that a critical juncture occurred …

Student Perceptions Of Vocabualry Gain During Study Abroad, Yuan Sui

Masters Theses

It is well acknowledged that study abroad is an ideal context to achieve high language proficiency. Previous studies show a relatively complex picture of the relationship of social interactions and language gains. On the one hand, students who study abroad experience language gains such as oral proficiency but on the other hand, researchers argue that study abroad does not guarantee language gains. Vocabulary as foundational knowledge of language learning has not received much attention in the context of study abroad, especially vocabulary learning strategies. The present study investigates the change of students’ perceived vocabulary gain via routine social activities with …

Spatial Effects Of Foreign Direct Investment (Fdi) On Poverty Reduction In Colombia: A Mixed Methods Approach, Mayra Alejandra Yat Aguilar

Masters Theses

Foreign direct investment (FDI) has been identified as an important factor in stimulating economic growth and decreasing poverty. In particular, the relationship between FDI and economic growth has been extensively debated in the academic literature but with mixed results. Meanwhile, considerably less work has been done towards investigating the effects of FDI on poverty reduction. Evidence from the limited research linking on FDI and poverty levels is also mixed. Through a more comprehensive survey-based multi-scale method of assessing poverty, this empirical study investigates the contribution of FDI with respect to concurrent quantitative and qualitative assessment of changes in living standards …
