Ocean Heat Wave Induces Breeding Failure At The Southern Breeding Limit Of The Northern Gannet Morus Bassanus, William A. Montevecchi, Paul M. Regular, Jean-François Rail, Kyran Power, Chris Mooney, Kyle J.N. D’Entremont, Stefan Garthe, Leanne Guzzwell, Sabina I. Wilhelm

Marine Ornithology

We document unprecedented abandonments and breeding failures by Northern Gannets in eastern Canada at Cape St. Mary’s, Bonaventure Island, and the Magdalen Islands. These events were associated with a marine heat wave during chick rearing in the late summer of 2012. The rapid onset of abandonment at Cape St. Mary’s also coincided with intense lightning and thunder during an overnight storm. Parental desertions at all colonies were transient, resolving over a period of weeks, and appeared to be food-related, resulting in the poorest breeding success on record for each of these colonies. The Northern Gannet’s primary prey during the breeding …

Twenty consecutive experimental sessions were performed, involving presentation of a plexiglass box containing food; the box could be opened and reached by pushing or pulling different lids, each leading to a food reward. Gulls were able to decrease their neophobic response throughout the course of the experiments. Fifty-three percent of individuals who entered the …

A Multidimensional Perspective Of Patterns Of Functioning And Well-Being, Lendi Nicole Joy

USF Tampa Graduate Theses and Dissertations

The Center for Behavioral Health Statistics and Quality estimates that 79.4% of U.S. adults will remain free from mental illness each year, but this does not necessarily mean they will enjoy positive psychological health and well-being. Well-being has been associated with positive outcomes such as greater health, longevity, work productivity, and increased social engagement. Thus, it is important for researchers to understand factors contributing to the development of well-being and optimal functioning. The current study used latent profile analysis to classify individuals based on their levels of well-being at ages 23 to 26 years and explored functioning indexes assessed when …

Comparison Of Offspring Growth Models In Atlantic Puffins Fratercula Arctica , Katja H. Kochvar, Raul Zabala Belenguer, Pierre-Paul Bitton

Marine Ornithology

Growth of morphological traits in the offspring of many seabirds, including Atlantic Puffins Fratercula arctica, has typically been characterized by linear models despite displaying nonlinear patterns. We assessed the fit of six typical avian growth models to measurements of puffling mass, wing length, and tenth primary length. Across all three biometrics, the first- and second-best performing models were nonlinear (i.e., quadratic, logistic, extreme value function); these models were then used to generate separate growth curves for individual pufflings and extract easily interpretable and comparable parameter estimates. We recommend the reported models in future studies incorporating metrics of puffling growth and …

Conflicting Social Information And Its Impact On Sentence Comprehension In Young Adults With Dld: An Eye Tracking Study, Ansley Davis

USF Tampa Graduate Theses and Dissertations

Individuals must recognize linguistic and non-linguistic social cues to resolve contextual ambiguities in their conversations. When the linguistic and social cues match, sentence processing is facilitated. However, conflicts between linguistic and social stimuli (i.e., incongruency) can lead to prediction errors which slow sentence processing. Limited research has explored the social cognition conflict resolution skills in individuals with Developmental Language Disorder (DLD) despite their documented emotion processing deficits. This study considers the role of social prediction processing in adults with DLD as they engage in a social cognition conflict resolution task.

Young adults with DLD (n=29) and typically developing (TD) peers …

An Exploratory Analysis Of Automated Deception Detection For Mental Health Applications, Sayde Leya King

USF Tampa Graduate Theses and Dissertations

Deception in mental health settings can undermine therapeutic relationships, compromise treatment efficacy, and impact patient outcomes. Yet, research shows that mental health clinicians often perform no better than chance at detecting deceptive behavior in therapy. Automated deception detection, leveraging artificial intelligence (AI) and multimodal behavioral cues—such as eye gaze, body gestures, and facial expressions—offers a promising alternative. However, most existing research focuses on high-stakes legal contexts, limiting its applicability to mental health settings.

This dissertation addresses this gap by pursuing three key research objectives using a mixed-methods approach. First, we investigate mental health clinicians’ perspectives on AI-assisted deception detection through …

Founded in 1884 to provide country holidays for poor London schoolchildren, the CCHF evolved from a philanthropic response to Victorian slum life into an informal arm of welfare governance by the end of the interwar period. Through its country holidays, the Fund became an active participant in shaping ideals of health, morality, and civic responsibility in a period marked by heightened concern over national vitality …

Physical Activity And Functional Mobility In Adults With Hearing Loss: A Series Of Embedded Studies Within A 6-Month Clinical Trial With Hearing Aids, Sarah L. Bochat

USF Tampa Graduate Theses and Dissertations

Adults with hearing loss engage in low levels of physical activity and demonstrate poor performance on measures of functional mobility. The impact of hearing rehabilitation on these outcomes is not fully understood. Previous investigations were largely quantitative and focused on older adults ≥ 65 years of age who may respond differently to hearing intervention than relatively younger adults. They also tended to focus on exercise rather than global engagement in physical activities and did not report hours of hearing aid use, an important indicator of intervention success. One purpose of this dissertation was to determine the feasibility of collecting accelerometry-assessed …
