Adjunct Faculty Perceptions Of Leadership And Cultures Of Engagement, Inclusion, Collaboration, And Value Through A Social Capital Theory Framework, Mary Athena Geron-Newton

Electronic Theses and Dissertations

At the time of this study, there were more adjunct or part-time teaching positions at colleges and universities than full-time or tenure track positions. It is predicted this trend will persist because it is fiscally beneficial to educational institutions; adjuncts will work for a quarter of the salary and with fewer benefits, no real job security, unpredictable teaching schedules, and no commensurate voice in faculty decisions. This case study expanded the understanding of the reasons behind contingent faculty's perceptions of satisfaction and their decisions to remain in instructional positions even with the positions' blatant inequities. According to Bourdieu's social capital …

Psychological Science Faculty Publications and Presentations

Increased stress among parents of youth with ASD has been well-documented. However, research on aspects of the parent-child relationship and subsequent links to parenting stress is limited. We assessed parents (N = 511) of youth with ASD to examine relations between parenting stress and parent-child quality time (amount of quality time, shared enjoyment, synchronicity). Elevated parenting stress was associated with less time spent engaging with youth in shared activities and decreased parent and child enjoyment during shared interactions. Parents with elevated stress reported engaging in shared activities and experiencing synchronicity with their child less often than parents below the …

The Pug Flap: Conjoined Profunda Artery Perforator And Upper Gracilis Flap For Breast Reconstruction, Isra Abdulwadood, Lacey R Pflibsen, Nicholas R Jarvis, Sebastian Winocour, Alanna M Rebecca, William J Casey, Edward M Reece

Faculty, Staff and Students Publications

Abdominal-based free flaps are the mainstay of autologous breast reconstruction; however, the region may not be ideal for patients with inadequate soft tissue or history of abdominal surgery. This case describes the use of a novel conjoined flap based on the profunda artery perforator and upper gracilis pedicles, named the perforator and upper gracilis (PUG) flap. This flap design aims to maximize medial thigh flap volume while ensuring robust tissue perforation. Here, we present our experience with the PUG flap in a breast cancer patient undergoing autologous reconstruction. The patient was a 41-year-old woman seeking nipple-sparing mastectomy and immediate autologous …

Staphylococcus Aureus Oleate Hydratase Produces Ligands That Activate Host Ppara, Christopher D. Radka, Matthew W. Frank, Tyler S. Simmons, Cydney N. Johnson, Jason W. Rosch, Charles O. Rock

Markey Cancer Center Faculty Publications

Commensal gut bacteria use oleate hydratase to release a spectrum of hydroxylated fatty acids using host-derived unsaturated fatty acids. These compounds are thought to attenuate the immune response, but the underlying signaling mechanism(s) remain to be established. The pathogen Staphylococcus aureus also expresses an oleate hydratase and 10- hydroxyoctadecanoic acid (h18:0) is the most abundant oleate hydratase metabolite found at Staphylococcal skin infection sites. Here, we show h18:0 stimulates the transcription of a set of lipid metabolism genes associated with the activation of peroxisome proliferator activated receptor (PPAR) in the RAW 264.7 macrophage cell line and mouse primary bone marrow-derived …

Objectives: To determine the prevalence of leukemia in the Aseer region of Saudi Arabia and the importance of hematological, biochemical and coagulation profiles for leukemic patients in the context of disease management. Methods: This retrospective study comprised 210 patients between 2012 and 2022 who had been diagnosed with leukemia at different ages. The multiple unpaired t-test was used to compare leukemic patients with control samples, which consisted of healthy individuals, and p <0.05 was taken as significant. The data was compiled from Aseer Central Hospital in the Aseer region and collected through peripheral blood smear and bone marrow biopsy (2012-2017) or by flow cytometry (2018-2022), according to the hospital information system and registry data. Results: Of the total 210 leukemic patients (61.4% males and 38.6% females), 104 cases (2012-2017) were diagnosed based on peripheral blood smear and bone marrow biopsy, and 106 cases (2018-2022) based on flow cytometry. Fifteen subtypes of leukemia were identified, with chronic myeloid leukemia being the most common (34.2%), followed by acute myeloid leukemia (17.6%), chronic lymphoblastic leukemia (11.9%), and B-cell acute lymphoid leukemia (9.5%). Other rare cases were also found. Conclusion: Of the 210 leukemia cases diagnosed in the Aseer region between 2012-2022, the most common subtype was chronic myeloid leukemia, followed by acute myeloid leukemia. In all leukemia subtypes, distinctive significant changes were observed in hematological parameters, biochemical parameters, and coagulation profiles.

Essays On Empirical Asset Pricing, Luying Wang

Dissertations and Theses Collection (Open Access)

The dissertation consists of three chapters on empirical asset pricing. The first chapter examines
the market return predictability of media coverage on climate change. Specifically, we introduce a
comprehensive media climate change concern (ΔCMCCC) index, derived from unexpected climate
change coverage across diverse media channels, including print (newspapers), voice (radio), and
video (television). We show that this index negatively predicts aggregate stock market returns, both
in-sample and out-of-sample, offering potential gains for investors. Our findings emphasize the
media’s influence on market returns through climate change discussions, mainly via the cash-flow
channel. This reveals possible shifts in product demand, while demand …

Nonlinear Interactions Of Sea‐Level Rise And Storm Tide Alter Extreme Coastal Water Levels: How And Why?, H. Moftakhari, D. F. Muñoz, A. Akbari Asanjan, A. Aghakouchak, Hamid Moradkhani, David A. Jay

Civil and Environmental Engineering Faculty Publications and Presentations

Sea-level rise (SLR) increasingly threatens coastal communities around the world. However, not all coastal communities are equally threatened, and realistic estimation of hazard is difficult. Understanding SLR impacts on extreme sea level is challenging due to interactions between multiple tidal and non-tidal flood drivers. We here use global hourly tidal data to show how and why tides and surges interact with mean sea level (MSL) fluctuations. At most locations around the world, the amplitude of at least one tidal constituent and/or amplitude of non-tidal residual have changed in response to MSL variation over the past few decades. In 37% of …
