Digital Footprints: Freedom On The Move At The University Of Kentucky, Vanessa Holden, Reinette F. Jones, Jennifer A. Bartlett, Kopana Terry

Library Presentations

During the late 18th through the mid-19th centuries, the Commonwealth of Kentucky saw significant movement of self-emancipated people seeking freedom from bondage. Often referred to as “runaways” or “fugitive slaves,” in historical texts, self-emancipated people defined freedom in many ways. These migrations were widely documented in newspaper advertisements known as fugitive slave advertisements and runaway ads in local newspapers published throughout the state. Access to these materials (often buried in databases or on microform) has been problematic at best. Enter the Self Emancipated and Enslaved People in Kentucky (SEEK) Project, a partnership between faculty in the University of Kentucky Libraries …

"Spreading Inoculation": The Effects Of Direct And Indirect Inoculation And Postinoculation Talk (Pit) On Graduate Students' Sense Of Belonging And Social Network Development During Socialization, Amanda Ruth Slone

Theses and Dissertations--Communication

During their first semester in graduate school, graduate students, many of whom are also employees of the university (BLS, 2019), encounter multiple challenges to successful socialization (Council of Graduate Schools, 2010; Weidman et al., 2001) —several of which are related to their sense of belonging (O’Meara et al., 2017; Pascale, 2018) — and if left unaddressed, these challenges can contribute to high attrition rates (Cassuto, 2013; Gardner & Barker, 2020), with one in four graduate students typically failing to graduate within ten years, even under favorable circumstances (Baum & Steele, 2017). Since the best time to influence an individual’s sense …

The Effects Of Controlling Language And Source Social Group Membership On Resistance To Persuasion, Zane A. Dayton

Theses and Dissertations--Communication

Persuasive attempts often fail. One theory that attempts to explain when and why people resist persuasion is psychological reactance theory (PRT; J. W. Brehm, 1966; S. S. Brehm & J. W. Brehm, 1981). According to the theory, people have an inherent desire to maintain their autonomy, or freedom. When they perceive that a persuasive message threatens their freedom, they experience psychological reactance, an aversive motivational state, which motivates them to restore their freedom by resisting the persuasive message. Whereas past studies have demonstrated that various message features (e.g., controlling language) and source characteristics (e.g., social group membership) can, individually, influence …

Forestry and Natural Resources Faculty Publications

Raptors exert top-down influences on ecosystems via their effects on prey population dynamics and community composition. Most raptors are sympatric with other predators, thus complicating our understanding of their relative influence in these systems. Estimates of kill rates and prey biomass recycling have been used as predation metrics that allow quantitative comparison among species and assessment of the relative role of single species within complex food webs. Few studies have produced findings of kill rates or prey biomass recycling for raptors. We used a supervised machine learning algorithm to behaviourally classify high resolution accelerometer informed GPS locations of tagged adult …
