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 …

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 …

A Tale Of Force: Examining Factors That Influence Police Officer Use Of Force, Kayla Preito-Hodge

Masters Theses

Police officer use of force in the United States is a growing concern to the American people. Although not based on solid empirical evidence, President Obama’s Task Force on 21^st Century Policing proposed several policies that address violent policing and the use of excessive force. In this study, I examine the relationship between policy recommendations and variations across police departments in their reported use of force.

This study draws on measures of use of force, community policing, education, and officer demographics from the 2013 Law Enforcement Management and Administrative Statistics (LEMAS) survey, combined with county-level demographic information from the …

Age Group Differences In Affect Responses To A Stressor, Molly Mather

Masters Theses

Older adults may be better able to modulate their emotional experiences than younger adults, and thus may recover more quickly from negative stressors. Additionally, older adults may be more likely to experience co-occurrence of negative and positive emotions in the setting of negative stressors, which may facilitate emotion recovery. To date, few studies have investigated the nature of age group differences in spontaneous emotional responses to a standardized stressor. The current study utilizes a laboratory mood manipulation to determine age group differences in emotion recovery in negative and positive affects, as well as age group differences in the co-occurrence of …

Borderline Personality And Risk-Taking: Examining The Role Of Impulsivity Across Domains, Colten Karnedy

Masters Theses

Individuals with borderline personality disorder (BPD) and high levels of BPD traits have demonstrated greater rates of engagement in risky, self-destructive behaviors compared to healthy controls. Specifically, impulsivity has been theorized to underlie many of these risky behaviors. Although existing self-report literature suggests that individuals with BPD are more impulsive than controls, evidence from behavioral measures remains inconclusive. Likewise, there is scant research examining specific domains of impulsivity associated with risky behaviors in BPD, which is problematic given that impulsivity is a diagnostic criterion for BPD. Thus, the proposed research aims to bridge this gap in the literature by examining …

Understanding Relational Competence In Emerging Adult Adoptees: A New Way To Conceptualize Competence In Close Relationships, Krystal K. Cashen

Masters Theses

Relatively little research has focused on the positive adjustment of emerging adult adoptees (Palacios & Brodzinsky, 2010). Given the developmental context of emerging adulthood (Arnett, 2000), it is important to select a measure of adjustment that reflects the increased ambiguity seen in this time period. The present study aims to develop and validate a measure of relational competence, or competence in one’s closest relationship regardless of relationship type (i.e., romantic vs. nonromantic). This measure will be created by adapting the Romantic Competence Interview, a measure of romantic competence previously used with emerging adults (Shulman, Davila, & Shachar-Shapira, 2011). Participants …

Assessing Adaptive Capacity Of Pioneer Valley Farmers, Angelica Carey

Masters Theses

This thesis explores Pioneer Valley farmers and their agricultural practices, knowledge and resources as they relate to climate change. Adaptive capacity is used throughout scientific literature, and often includes numerous components; for this thesis the measurement of farmers’ adaptive capacity would be assessed according to only three components: knowledge, past experiences and use of resources. Climate change and its impacts on agriculture have been studied but what is unclear is how prepared farmers are to deal with these impacts. Through literature review, survey development and recorded interviews, data was then analyzed both for quantitative and qualitative results to understand farmer’s …
