Weighted Networks: Applications From Power Grid Construction To Crowd Control, Thomas Charles Mcandrew

Graduate College Dissertations and Theses

Since their discovery in the 1950's by Erdos and Renyi, network theory (the study of objects and their associations) has blossomed into a full-fledged branch of mathematics.

Due to the network's flexibility, diverse scientific problems can be reformulated as networks and studied using a common set of tools.

I define a network G = (V,E) composed of two parts: (i) the set of objects V, called nodes, and (ii) set of relationships (associations) E, called links, that connect objects in V.

We can extend the classic network of nodes and links by describing the intensity of these associations with weights. …

Examining Disparities In Long-Distance Travel Access, Hannah Catherine Ullman

Graduate College Dissertations and Theses

This thesis examines several nuanced issues, including equitable access, regarding long-distance intercity travel. In the United States, studies of transportation equity focus on affordable access to local destinations and basic services. The limited studies of long-distance intercity travel focus on observed demand, ignoring latent or unmet demand. Both quantitative and qualitative data are used to explore the differences between those who participate in long-distance travel and those with unmet need for it. This thesis found that the ability to participate in long-distance travel plays a role in one’s overall well-being. Undertaking long-distance trips facilitates access to opportunity for cultural and …

Hike Your Own Hike: Cosmopolitanism And Applied Behavior Analysis Explored Through Spn, Caitlin Brianna Walsh

Graduate College Dissertations and Theses

Ever since I started working with animals, I felt an intrinsic motivation to develop relationships based on trust and mutual admiration. Working in the horse world, I became dismayed at the coercive methods used to assure progress and achieve competition goals. I moved to Burlington to pursue a career helping children. Working as a behavior interventionist I felt peace and satisfaction as I utilized my previous skills and knowledge learned from my work with animals and my undergraduate education. After about a year of work, I started to become frustrated and dismayed at the treatment of some of our children. …

Protein Kinase Mzeta (Pkm-Ζ) Regulates Kv1.2 Dependent Cerebellar Eyeblink Classical Conditioning, Kutibh Chihabi

Graduate College Dissertations and Theses

Learning and memory has been a topic that has captured the attention of the scientific and public communities since the dawn of scientific discovery. Without the faculty of memory, mammals cannot experience nor function in the world; among homosapiens specifically, language, relationships, and personal identity cannot be developed (Eysenck, 2012). After all, some philosophers such as John Locke argued we are nothing but a collection of past memories in which we have developed and improved upon (Nimbalkar, 2011).

Understanding the cellular mechanisms behind learning, and the subsequent formation of memory, has been a topic that has garnered scientific interest for …

Making I-Contact: Fostering Shared, In-The-Moment Subjective Experiences, Mark Huneke

Graduate College Dissertations and Theses

Numerous research studies have offered evidence that I-sharing (perceived subjective similarity) facilitates interpersonal connection (e.g. Huneke & Pinel, 2016; Pinel, Long, Landau, Alexander, & Pyszczynski, 2006; Pinel & Long, 2012). Despite this research, no interventions currently exist to foster I-sharing between individuals, thereby leaving interventionists and others unable to utilize I-sharing to nurture authentic connections. The current dissertation takes an important step in the direction of developing usable interventions based on I-sharing research. Specifically, I examine the effectiveness of a technique designed to foster I-sharing genuinely between individuals. Building on I-sharing theory, which specifies that people most confidently believe that …

Designing For Economic Success: A 50-State Analysis Of The Genuine Progress Indicator, Mairi-Jane Venesky Fox

Graduate College Dissertations and Theses

The use of Gross Domestic Product (GDP) as the primary measure of economic progress has arguably led to unintended consequences of environmental degradation and socially skewed outcomes. The Genuine Progress Indicator (GPI) was designed to reveal the trade offs associated with conventional economic growth and to assess the broader impact of economic benefits and costs on sustainable human welfare. Although originally designed for use at the national scale, an interest has developed in the United States in a state-level uptake of the GPI to inform and guide policy. However, questions exist about the quality and legitimacy of the GPI as …

Exploration Of New Methods In Long Distance Transportation Data Collection And Tourism Travel In Vermont, Benjamin Kaufman

Graduate College Dissertations and Theses

ABSTRACT

Human transportation patterns have continued to shift and increase in rate as technology has made travel between spatially disparate locations more feasible. These movements are responsible for approximately one third of global carbon emissions, and account for one half of Vermont’s greenhouse gas output. Modeling transportation behaviors is difficult due to changing travel patterns and issues of surveying human participants. Long distance travel patterns are especially difficult and have not received the attention that urban mobility has within the literature.

In this Masters thesis, I describe current methods of transportation data collection and propose new methods, as well as …

The Psychopathic Personality: Measurement, Variants, And Utility Of The Construct, Melissa L. Paiva-Salisbury

Graduate College Dissertations and Theses

Antisocial behaviors (AB), which place an enormous burden on society, are committed by a heterogeneous population, including psychopaths (Poythress et al., 2010). Psychopathy denotes a more serious and entrenched pattern of AB (Hare, 1996) and appears to be a heterogeneous construct as well. In fact, Primary and Secondary psychopathic variants are consistently identified in a variety of samples using person-centered analysis (Drislane et al., 2014; Gill & Stickle, 2016). Both Reinforcement Sensitivity Theory (Gray & McNaughton, 2000) and the Triarchic Model of Psychopathy (Patrick, Fowles, & Krueger, 2009) provide useful frameworks to understand the etiology of the psychopathic variants. The …

Conceptualizing And Measuring Food Security Among Resettled Refugees Living In The United States, Hannah Stokes

Graduate College Dissertations and Theses

Food security research with resettled refugees in the United States and other Global North countries has found alarmingly high rates of food insecurity, up to 85% of surveyed households. This is well above the current US average of 12.7%. However, the most common survey tool used to measure food security status in the US, the US Household Food Security Survey Module (HFSSM), has not been sufficiently validated for resettled refugee populations, leading to the risk that the HFSSM may actually be underestimating the prevalence of food insecurity among resettled refugees in the US. Though research has attempted to establish validity …

College Students' Development Of Civic Commitment: Experiences Of Service Learning Across The College Years, Kailee Ann Brickner-Mcdonald

Graduate College Dissertations and Theses

Functional democracy in a just society requires citizens who are complex thinkers and skilled, caring leaders. This study examines how undergraduate college students become committed citizens, the kind demanded by our changing world. In particular, it addresses the developmental and experiential factors that influence students' journeys of commitment to the public good, and how students understand their lived experiences integrating these diverse influences. Framed by my constructivist epistemology, I used the qualitative tradition of narrative inquiry to address these questions. I interviewed twelve highly engaged students about their experiences in diverse community-based work and learning over four years of college. …

Shaping Policy In The Anthropocene: Gender Justice As A Social, Economic And Ecological Challenge, Phoebe Spencer

Graduate College Dissertations and Theses

Environmental pressures such as natural disasters, resource scarcity, and conflict related to climate change have emphasized the importance of considering social justice within its ecological context. Gender inequality is one type of injustice that has traditionally been addressed as a social matter, yet gendered divisions in bargaining power, mobility, and access to resources are exacerbated by environmental instability. One barrier to gender equity in the face of a changing climate is the mainstream economic paradigm, which promotes growth and individualism, often at the cost of environmental and social wellbeing. The issue of gender inequality in the Anthropocene, the proposed geological …

Predictive Modeling Of Adolescent Cannabis Use From Multimodal Data, Philip Spechler

Graduate College Dissertations and Theses

Predicting teenage drug use is key to understanding the etiology of substance abuse. However, classic predictive modeling procedures are prone to overfitting and fail to generalize to independent observations. To mitigate these concerns, cross-validated logistic regression with elastic-net regularization was used to predict cannabis use by age 16 from a large sample of fourteen year olds (N=1,319). High-dimensional data (p = 2,413) including parent and child psychometric data, child structural and functional MRI data, and genetic data (candidate single-nucleotide polymorphisms, "SNPs") collected at age 14 were used to predict the initiation of cannabis use (minimum six occasions) by age 16. …

Sugar-Sweetened Beverage Taxes In Vermont: Media Framing And Public Perception, Benjamin Lloyd Crosby

Graduate College Dissertations and Theses

This thesis explores the conversation surrounding the recent attempts by the Vermont Legislature to pass a Sugar-Sweetened Beverage tax in the years 2014-2016. We explore the common perceptions expressed by a sample of Vermont residents and also look at how Vermont media outlets portrayed the tax through frames of reference. Framing is a method of emphasizing certain points of an issue. This thesis reports the common opinions of Vermonters, the media framing of the issue, and if there is any relationship between them in two academic journal articles.

The first article looks at the common frames used in Vermont media …

"Don't Tell Them I Eat Weeds," A Study Of Gatherers Of Wild Edibles In Vermont Through Intersectional Identities, Elissa J. Johnson

Graduate College Dissertations and Theses

As wild edibles gain in popularity both on restaurant menus and as a form of recreation through their collection, research on contemporary foragers/wildcrafters/gatherers of wild edibles has so increased from varied disciplinary perspectives. Through an exploration of gatherers in Vermont, I examine the relationships between practice and identity. By employing intersectionality through feminist ethnographic methods, this research recognizes the complex intersections of individuals' identities that challenge a more simplified, additive approach to definitions of race, class, gender and the myriad identities that inform one's experience of privilege and oppression. As prior scholarship has established, people from diverse ethnicities, genders, religions, …

The Moderating Role Of Rsa Baseline, Reactivity, And Recovery In The Link Between Parental Socialization Of Emotion Regulation And Children's Internalizing Symptoms, Wesley Sanders

Graduate College Dissertations and Theses

In this study I examined the moderating effect of three profiles of respiratory sinus arrhythmia (RSA at baseline, in response to a stressor, and in recovery from a stressor) on the relationship between parental emotion socialization during an emotion-related discussion and parental report of child internalizing symptoms 6 months later. Parents were observed during an emotion discussion task and coded for their use of emotion encouragement and general positive involvement. A total of 65 families with children between the ages of eight and ten years old completed this task while RSA scores were obtained from children during baseline, task, and …

Transitions In Subtypes Of Withdrawn Behavior From Childhood To Adolescence: The Role Of Sports Participation, Meghan Conboy Schreck

Graduate College Dissertations and Theses

Withdrawn behavior broadly describes individuals who are isolated from their peer group. Though not a clinical disorder, withdrawn behavior is a construct involved in many psychological problems, and it is likely the behavioral manifestation of distinct motivations and developmental processes. Additionally, withdrawn behavior is often used interchangeably with other psychological constructs, including shyness, social disinterest, and peer exclusion, making accurate classification difficult. In an effort to better understand the classification and developmental course of withdrawn behavior in youth, the current study used latent class analysis (LCA) and latent transition analysis (LTA) to identify distinct subclasses of withdrawn youth and to …

Social And Emotional Dimensions Of Succession Planning For Family Forest Owners In The Northeastern United States, Hallie E. Schwab

Graduate College Dissertations and Theses

Keeping forestland intact has emerged as a critical policy objective at state and federal levels. This target has been supported by substantial public investment. The collective impact from the bequest decisions of millions of landowning individuals and families has the potential to affect the extent and functionality of future forests in the United States. Despite a growing body of research devoted to studying these transitions in forest ownership, much remains unknown about how family forest owners make decisions in this arena. The social and emotional dimensions of woodland succession planning have been particularly under-examined. This thesis explores the process of …

The Influence Of Adverse Childhood Experiences, Families, Neighborhoods, And School Environments On Cognitive Outcomes Among Schoolchildren, Mark William Olofson

Graduate College Dissertations and Theses

Schools, families, and neighborhoods can support the development of happy, healthy children and adolescents. However, a majority of children in the United States also experience adversity in their early lives that can have deleterious effects on their cognitive and socioemotional development. Measuring and modeling early adversity is fundamental to understanding development as it occurs through interactions with schools, families and neighborhoods. As outlined by Bronfenbrenner's bioecological model of human development, proximal and distal forces shape development, and cannot be isolated when relating measures of the developmental context to outcomes for individuals. For schools and other social programs to support students …

Comparing The Effects Of Menthol Status On The Behavioral Pharmacology Of Smoking Reduced Nicotine Content Cigarettes, Danielle Davis

Graduate College Dissertations and Theses

Introduction: An active area of tobacco regulatory science research focuses on examining the effects of varying the nicotine content of cigarettes as part of a potential national policy to lower their nicotine content levels to reduce addiction potential. The present study examines differences in the behavioral effects of reduced nicotine content cigarettes related to their menthol status. Menthol is the only cigarette flavoring that is still legally permissible according to Food and Drug administration regulations.

Methods: Participants were 26 current adult smokers from three populations especially vulnerable to tobacco use and addiction (economically disadvantaged women, opioid-dependent individuals, individuals with affective …

Renewal In The Context Of Stress: A Potential Mechanism Of Stress-Induced Reinstatement, Scott Timothy Schepers

Graduate College Dissertations and Theses

In the animal laboratory, stressors can produce the relapse of drug-seeking behaviors after the behavior has been inhibited by extinction. This type of relapse has been called stress-induced reinstatement, and it models the relapse that is commonly reported in human populations. Interestingly, in the laboratory, stress does not typically reinstate extinguished behaviors that have been reinforced by food. One account of the discrepancy is that drugs of abuse may induce stress; therefore, when organisms learn to respond for drugs, they might learn to make the response in the “context” of stress. If so, then stress-induced reinstatement may be better described …

The Impact Of Stigma On The Mental Health Of Resettled African And Asian Refugees, Victoria M. Baptiste

Graduate College Dissertations and Theses

The global refugee crisis worsens day-by-day, with millions of refugees forced to seek safe haven abroad. Pre-migration trauma exposure contributes to disproportionately higher rates of psychopathology, especially among torture survivors and women. The extant literature has largely focused on the effects of pre-migration factors; however, increasingly, researchers recognize the critical impact of post-migration living difficulties (PMLD) in exacerbating refugee mental health. One example of a PMLD is stigma, defined as a socially devalued attribute (e.g., minority race, ethnicity, sex). A robust literature documents the deleterious effects of stigma on psychological functioning, but few studies of refugees have explored stigma, which …

Multidimenional Assessment Of Parenting Across Three Developmental Stages, Justin Parent

Graduate College Dissertations and Theses

BACKGROUND: The primary aim of the current study was to create a new measure of parenting practices, constituted by items from already established measures in order to advance the measurement of parenting practices in clinical and research settings. The current study utilized five stages designed to select only the best parenting items, establish a factor structure consisting of positive and negative dimensions of parenting, meaningfully consider child developmental stage, ensure strong psychometric properties, and provide initial evidence for the validity of the final measure.

METHODS: A total of 1,790 parents (44% fathers) were recruited online through Amazon's Mechanical Turk for …

Comparing The Smoking Topography Of Usual Brand Cigarettes In Pregnant And Non-Pregnant Smokers, Cecilia Louise Bergeria

Graduate College Dissertations and Theses

Introduction: Most pregnant smokers report abruptly reducing their cigarettes per day (CPD) by ~50% shortly after learning of pregnancy and of making further smaller reductions over the remainder of their pregnancy. Laboratory and naturalistic studies with non-pregnant smokers have found that these types of reductions often lead to changes in smoking topography (i.e., changes in smoking intensity to maintain a desired blood-nicotine level). 19, 20 If pregnant women engage in compensatory smoking, they may expose themselves and their offspring to the same level of toxicants despite reporting reductions in CPD.

Methods: Pregnant and non-pregnant female smokers (n = 17 and …

Examining The Socialization Of Physical Education Teachers: A Case Study, Thomas Matthew Geisler

Graduate College Dissertations and Theses

In the last thirty years childhood obesity and inactivity rates in the United States have increased at alarming rates (Ogden, Carroll, Kit, & Flegal, 2014). In response to this, physical education curriculum is shifting to focus more on health promotion rather than competitive team sports and game play. This focus is reflected in the recently revised K-12 physical education national content standards and learning outcomes and is impacting how colleges are preparing future teachers (SHAPE America (Organization), Couturier, Chepko, & Holt/Hale, 2014). Changing how physical education is taught can be challenging for teacher educators, in part due to the fact …

What’S In Your Body Of Water? Reducing The Psychological Distance Of Pharmaceutical Pollution Through Metaphor In Risk Communication, Alexandra Z. Millarhouse

Graduate College Dissertations and Theses

Aquatic pharmaceutical pollution poses ecotoxicological risks to the environment and human health. Consumer attitudes and behavior represent a significant source of pharmaceutical compounds found in water. Thus, understanding public perceptions of aquatic pharmaceutical pollution and developing effective risk communication techniques are critical to engaging society in the type of widespread change necessary for addressing the presence of pharmaceuticals in water. This mixed-methods study applies conceptual metaphor theory in conjunction with construal level theory of psychological distance to assess how metaphoric framing affects perceptions of aquatic pharmaceutical contamination across four principal dimensions of psychological distance (geographic, social and temporal distance and …

Cues Associated With Alternative Reinforcement Can Attenuate Resurgence Of An Extinguished Instrumental Response, Sydney Trask

Graduate College Dissertations and Theses

In resurgence, a target behavior (R1) is acquired in an initial phase and extinguished in a second phase while an alternative behavior (R2) is reinforced. When reinforcement for the second response is removed, however, R1 behavior returns or “resurges.” The resurgence paradigm may have implications for understanding relapse after behavioral interventions in humans such as contingency management, or CM, in which (for example) drug users can earn vouchers contingent upon drug abstinence. The present experiments examined the effectiveness of a putative retrieval cue for treatment in attenuating the resurgence effects and determined the likely mechanism by which this cue functions. …

The Impact Of Depression On Treatment Adherence And Cardiorespiratory Fitness In Cardiac Rehabilitation, Sheau-Yan Ho

Graduate College Dissertations and Theses

Major depression and coronary heart disease are two strongly linked, major causes of death and disability. After an acute coronary event, many patients are referred to cardiac rehabilitation (CR), a medically supervised exercise intervention and lifestyle training program. Depression may partially account for poor CR adherence and resulting cardiovascular problems in patients with a history of heart disease; however, underlying mechanisms through which depression impacts cardiac functioning are not well understood. The current project tests a theoretical model in which CR adherence (i.e., number of CR sessions attended) mediates the relation between baseline depression and cardiorespiratory fitness after CR. A …

Role Of Community Social Capital For Acute Food Security Following An Extreme Weather Event, Alana N. Chriest

Graduate College Dissertations and Theses

Worsening climate changes effects are predicted to increase the severity and frequency of extreme weather events (EWE), which can disrupt food systems, from the local to global level, and compromise community food security. In the rural U.S., food insecurity, poverty, low economic growth, and population loss are prevalent, and rural communities often lack the physical capital to bolster community resiliency to climate change adaptation. In 2011, Tropical Storm Irene (TS Irene) in Vermont was the most damaging EWE the state’s history. Severely damaged roads, infrastructure, homes, and land, rendered many rural towns isolated for up to several days. The levels …

Poutine, Mezcal And Hard Cider: The Making Of Culinary Identities In North America, Nicolas Fabien-Ouellet

Graduate College Dissertations and Theses

Foodways, which in short refers to eating and drinking practices, are constitutive of personal and group identity. In this thesis, I explore the symbolic values of food and drink in group identification processes evolving across North America. Through the cases of poutine, mezcal, and hard cider, I investigate cultural identity formation, negotiation, and transformation; from everyday practices to global interactions. What I develop in this thesis is a rationale that can be actively used by members of a group, as well as by community development practitioners, governments, and industry stakeholders to bolster community capitals and agency through making, supporting or …

Emission Permits As A Monetary Policy Tool: Is It Feasible? Is It Ethical?, Tracey Mccowen

Graduate College Dissertations and Theses

The price of emission permits is deemed too low to mitigate climate change. In three studies, policy approaches to pricing carbon in a market setting are examined. First, the emission permit market is analyzed comparatively to how the ethanol mandate impacted prices in the corn market. This leads to the realization that the marketization of carbon is more like a currency than a physical commodity. The next study examines emission permits as a monetary policy tool. Emissions correlate GDP output, thus central banks can use emission permits as forward guidance, as a means to optimize the price for climate change …
