The Origins Of Manufactured Dissent And The Efficacy Of Climate Change Narratives, Emma Elisabeth Giering

Graduate College Dissertations and Theses

The year of 2020 revealed many things about the fragility of socially constructed institutions and the public trust which grants such entities legitimacy, which is perhaps what reinvigorated social discourse surrounding the existential threat posed by climate change. Amid a pandemic, Americans watched wildfires engulf much of the west coast, environmental regulations unravel in the hands of the Trump administration, and Wall Street begin trading futures contracts on the U.S.’s water supply. Given the ever-expanding record of environmental travesties, how are citizens to respond, and from where should they derive their inspiration for response?

This thesis answers the above question …

The Role Of Infralimbic Cortex In Switching Between An Instrumental Behavior’S Status As A Goal-Directed Action Or Habit, Matthew Broomer

Graduate College Dissertations and Theses

In instrumental learning, extensive training of a response typically generates a habit. The transition from goal-directed to habitual behavioral control is often considered unidirectional; however, recent evidence suggests this is not the case. Under certain conditions, goal-directed control may be restored to a behavior that was previously habitual. We identify the infralimbic cortex (IL) as a participant in this process and draw on both instrumental learning and fear extinction literatures to further our understanding of IL function.

Four experiments explored the role of IL in flexible behavior. Experiments 1a and 1b were instrumental learning experiments. Experiment 1a used a previously …

Examining Sex Differences In Habit Formation: Effects Of Methamphetamine Sensitization And Contributions Of Ovarian Hormones, Hannah Schoenberg Book

Graduate College Dissertations and Theses

In the early stages of instrumental learning, behavior is goal-directed and sensitive to changes in the value of the instrumental outcome. As learning progresses, an association forms between the response and stimuli within the learning environment, such that after sufficient repetition, responding is evoked automatically in the presence of these stimuli and is insensitive to changes in outcome value. The reflexive nature of these types of behaviors has led to their classification as instrumental habits. The emergence of habitual behavior is thought to involve parallel processes that are mediated by distinct neural substrates. Regions of the prefrontal cortex, amygdala, and …

Vermont Special Educators’ Perceptions On The Inclusion Of Students With Disabilities In Universal Positive Behavioral Interventions And Supports (Pbis), Cassandra L. Townshend

Graduate College Dissertations and Theses

AbstractOver the last 25 years, there has been an increased body of research on best practices to address the social, emotional, and behavioral well-being of all students in schools. Positive Behavior Interventions and Supports (PBIS) has consistently demonstrated effectiveness in attending to all students’ social, emotional, and behavioral wellbeing – including students with disabilities (Simonsen et al., Feb., 2020). Despite PBIS being implemented in over 27,000 schools in the United States (Horner & Sugai, 2015) and in over 50% of schools Vermont, minimal research has been conducted on the experiences of special educators and their perceptions of PBIS practices on …

How And Why Do People Value Nature? An Examination Of Nonmaterial Aspects Of Human-Nature Interactions., Tatiana Marquina

Graduate College Dissertations and Theses

Nonmaterial benefits from nature, often labeled as cultural ecosystem services, represent a core dimension of human well-being. Yet despite their importance, these benefits and associated values remain overlooked in environmental assessments and decisions.

This dissertation applies insights from multiple disciplines to document nonmaterial dimensions of human-nature interactions across geographic contexts and user groups. As nonmaterial benefits can be hard to elicit and measure, this work uses multiple existing data collection methods and tests a novel data collection tool. First, I use a qualitative study design to explore values and stewardship practices associated with urban foraging in New York City, NY. …

Exploring Weight Control Expectancies As A Mediator Of The Relationship Between Fear Of Fat And Nicotine Dependence In Smokers And Vapers, Emily Pomichter

Graduate College Dissertations and Theses

Specific drug-use expectancies are shaped by reports from others about the effects of the drug, by an individual’s own experience with the drug, or by both. The present study hypothesized that, among smokers and e-cigarette users (vapers), an individual’s fear of weight gain would be associated with higher endorsement of appetite and weight control expectancies from nicotine use, which in turn would be associated with self-reported levels of nicotine dependence. The participants were smokers (n = 514) and vapers (n = 412) who responded to a Qualtrics survey advertised via Amazon’s Mechanical Turk platform. As predicted, nicotine’s appetite and weight …
