Battle Over Black Bears: Investigating Perceptions Of The Black Bear Hunting Referendums In Maine, Francesca A. Gundrum

Electronic Theses and Dissertations

Human dimensions of wildlife is an emerging discipline that seeks to understand the complex relationships between people, wildlife, and their conflicts and/or interactions (Decker, Riley, & Siemer, 2012). Human dimensions utilizes several tested theoretical frameworks to investigate these complexities, such as cognitive hierarchy theory and wildlife value orientations (WVOs). Both of these theoretical frameworks were examined in this study, which investigated the content of news media during controversial American black bear (Ursus americanus) hunting referenda in Maine, and key stakeholder perceptions of black bear management. Maine is the only state that allows hunters to take a black bear over bait, …

Cognitive, Mood, And Cardiovascular Reactivity And Recovery In Response To Sadness In Remitted Major Depressive Disorder, Olivia Bogucki

Electronic Theses and Dissertations

Major depressive disorder is marked by high rates of relapse and recurrence. Research has suggested that formerly depressed individuals exhibit dysphoric mood or dysfunctional beliefs that are similar to currently depressed individuals while in a dysphoric, but not euthymic, mood and these changes prospectively predict relapse and recurrence over time.While there is still disagreement as to whether dysfunctional thinking or dysphoric mood characterizes remitted depression, these changes appear to be mood state dependent, or undetectable until activated by sadness. These findings have led to the hypothesis that cardiovascular functioning may also be mood state dependent in remitted depression; however, this …

New Methodologies For Examining And Supporting Student Reasoning In Physics, John C. Speirs

Electronic Theses and Dissertations

Learning how to reason productively is an essential goal of an undergraduate education in any STEM-related discipline. Many non-physics STEM majors are required to take introductory physics as part of their undergraduate programs. While certain physics concepts and principles may be of use to these students in their future academic careers and beyond, many will not. Rather, it is often expected that the most valuable and longlasting learning outcomes from a physics course will be a repertoire of problem-solving strategies, a familiarity with mathematizing real-world situations, and the development of a strong set of qualitative inferential reasoning skills.

Characterization Of Ethanol-Related Phenotypic Differences Between C57bl/6j And C57bl/6nj Substrains: Role Of Cyfip2?, Matthew C. Hartmann

Electronic Theses and Dissertations

The C57BL/6 (B6) mouse is the most commonly used inbred strain in biomedical research, and has served as the basis for various large-scale genetic and genomic projects. Although the parental substrain, C57BL/6J (B6J), originated at The Jackson Laboratory, isolated breeding colonies are now maintained at numerous sites. This separation has resulted in genetic drift that has led to the emergence of phenotypic differences among these colonies. For instance, B6J mice display higher levels of voluntary ethanol consumption and increased locomotor responses to psychostimulants, relative to C57BL/6N mice (B6N). Initial progress has been made in elucidating the genetic bases of these …

Local Food Policy & Consumer Food Cooperatives: Evolutionary Case Studies, Afton Hupper

Electronic Theses and Dissertations

Darwin’s theory of natural selection has played a central role in the development of the biological sciences, but evolution can also explain change in human culture. Institutions, mechanisms that govern behavior and social order, are important subjects of cultural evolution. Institutions can help stabilize cooperation, defined as behavior that benefits others, often at a personal cost. Cooperation is important for solving social dilemmas, scenarios in which the interests of the individual conflict with those of the group. A number of mechanisms by which institutions evolve to support cooperation have been identified, yet theoretical models of institutional change have rarely been …

Mechanisms Of Humility's Influence On Prosociality, Matthew A. Humphreys

Electronic Theses and Dissertations

Prosocial behavior is valuable for the people it is meant to help, the people engaging in the behavior, and society in general. However, we do not always behave prosocially. Through three studies (N = 535) this work examined the possibility that resource scarcity might reduce prosocial behavior and that humility might promote prosocial behavior by both reducing the negative effect of scarcity on prosocial behavior, and by its own positive relationship with prosociality. This work further examined facets of humility that might promote prosocial behavior, such as other-orientation, and the roles of state and trait humility. Humility was associated with …
