High-Impact Learning Experiences And Post-Graduate Outcomes: Exploring The Influence On Employment, Continuing Education And Salary, Alison Handy Twang

The SUNY Journal of the Scholarship of Engagement: JoSE

With the cost of college on the rise, and students increasingly viewing college as a pathway to a successful career, colleges and universities are under increasing pressure to demonstrate evidence of their effectiveness. High-impact learning experiences, such as internships, study abroad, service-learning, capstones and undergraduate research, have emerged as a promising practice to enhance student development during college; however, few studies have examined the impact of such practices on post-graduate indicators of success. This paper adds to our understanding of the benefits of high-impact learning by examining their influence on student post-graduate employment, continuing education and starting salary. The data …

Injection Of Electron Beams Into Two Laser Wakefields And Generation Of Electron Rings, Q. Chen, Dominika Maslarova, J. Wang, S. Li, Donald Umstadter

Department of Physics and Astronomy: Faculty Publications

Mutual injection of electron beams into two laser plasma wakefields was observed experimentally when driving laser pulses interfered in plasma at a small crossing angle and were slightly relatively delayed, approximately by one pulse duration. Particle-in-cell simulations revealed that the mutual injection was sensitive to the spatial overlap of the laser pulses, which therefore could be used to control the mutual injection. The dual synchronized, femtosecond electron beams are potentially useful for pump-probe experiments in ultrafast science. In addition, out-of-axis ring-shaped electron beams were detected in both experiments and simulations.

Adding Gene Transcripts Into Genomic Prediction Improves Accuracy And Reveals Sampling Time Dependence., Bruno C Perez, Marco C A M Bink, Karen L. Svenson, Gary Churchill, Mario P L Calus

Faculty Research 2022

Recent developments allowed generating multiple high-quality 'omics' data that could increase the predictive performance of genomic prediction for phenotypes and genetic merit in animals and plants. Here, we have assessed the performance of parametric and nonparametric models that leverage transcriptomics in genomic prediction for 13 complex traits recorded in 478 animals from an outbred mouse population. Parametric models were implemented using the best linear unbiased prediction, while nonparametric models were implemented using the gradient boosting machine algorithm. We also propose a new model named GTCBLUP that aims to remove between-omics-layer covariance from predictors, whereas its counterpart GTBLUP does not do …

Integrating Psychopathy Into Prominent Developmental/Life-Course Theories, Eva M. Fontaine

USF Tampa Graduate Theses and Dissertations

Despite empirical research identifying psychopathy as one of the most robust predictors of criminal behavior, calls to integrate psychopathy into criminological theory have largely been unrequited. Within criminological theory, the construct of psychopathy has been proposed to best fit in the developmental/life-course (DLC) paradigm. As such, the purpose of this dissertation was to explore the theoretical integration of into psychopathy into three DLC theories: (1) Moffitt’s (1993) Dual Taxonomy, (2) Gottfredson & Hirschi’s (1990) General Theory of Crime, and (3) DeLisi’s (2009) Unified Theory of Crime. In doing so, the three studies in this dissertation employed the Pathways to Desistance …

Visual Ecology: Sensing The Social World, Elliott P. Steele

Dartmouth College Ph.D Dissertations

Social animals, and even solitary animals, must at different points in their life actively search for and locate conspecifics within their environment, using one or multiple senses. One sense in particular, vision, can provide some of the most spatially detailed and temporally rapid information about the environment. Yet, the surrounding environment can also severely challenge animals’ abilities to find fellow conspecifics. Furthermore, once an animal successfully locates conspecifics, it must then make key decisions about when and where to enter group formations, decisions which may strongly impact their access to socially-acquired resources. Even after an animal has positioned itself within …

Blockade Of Fgf2/Fgfr2 Partially Overcomes Bone Marrow Mesenchymal Stromal Cells Mediated Progression Of T-Cell Acute Lymphoblastic Leukaemia, Chen Tian, Yueyang Li, Lina Wang, Junqi Si, Yaxin Zheng, Junnan Kang, Yafei Wang, M James You, Guoguang Zheng

Faculty, Staff and Student Publications

The development of acute lymphoblastic leuakemia (ALL) is partly attributed to the effects of bone marrow (BM) microenvironment, especially mesenchymal stromal cells (MSCs), which interact bilaterally with leukaemia cells, leading to ALL progression. In order to find MSCs-based microenvironment targeted therapeutic strategies, Notch1-induced T-cell ALL (T-ALL) mice models were used and dynamic alterations of BM-MSCs with increased cell viability during T-ALL development was observed. In T-ALL mice derived stroma-based condition, leukaemia cells showed significantly elevated growth capacity indicating that MSCs participated in leukaemic niche formation. RNA sequence results revealed that T-ALL derived MSCs secreted fibroblast growth factor 2 (FGF2), which …

Uses And Benefits Of Algae As A Nutritional Supplement For Honey Bees, Benjamin J. Nichols, Vincent A. Ricigliano

Department of Entomology: Faculty Publications

Honey bees are essential agricultural pollinators that are threatened by various interacting stressors, posing risks to beekeeping industries and human food security. Malnutrition is a major factor underlying managed bee colony losses that can be countered by feeding artificial diets, which aim to deliver essential macro- and micronutrients. Current bee nutritional supplements show room for improvement and require resources that compete with human food production. Algae and microalgae in particular have been gaining traction in the literature as alternative feed sources and nutritional supplements for livestock, including honey bees. Herein, we review the current literature and categorize the effects of …

Do Pharmaceuticals In The Environment Pose A Risk To Wildlife?, Thomas G. Bean, Elizabeth A. Chadwick, Marta Herrero‐Villar, Rafael Mateo, Vinny Naidoo, Barnett A. Rattner

United States Geological Survey: Staff Publications

The vast majority of knowledge related to the question “To what extent do pharmaceuticals in the environment pose a risk to wildlife?” stems from the Asian vulture crisis (>99% decline of some species of Old World vultures on the Indian subcontinent related to the veterinary use of the nonsteroidal anti‐inflammatory drug [NSAID] diclofenac). The hazard of diclofenac and other NSAIDs (carprofen, flunixin, ketoprofen, nimesulide, phenylbutazone) to vultures and other avian species has since been demonstrated; indeed, only meloxicam and tolfenamic acid have been found to be vulture‐safe. Since diclofenac was approved for veterinary use in Spain and Italy in …

Exploring Membrane Binding Targets Of Disordered Human Tau Aggregates On Lipid Rafts Using Multiscale Molecular Dynamics Simulations, Kwan H. Cheng, Angela Graf, Amber Lewis, Thuong Pham, Aakriti Acharya

Physics and Astronomy Faculty Research

The self-aggregation of tau, a microtubule-binding protein, has been linked to the onset of Alzheimer’s Disease. Recent studies indicate that the disordered tau aggregates, or oligomers, are more toxic than the ordered fibrils found in the intracellular neurofibrillary tangles of tau. At present, details of tau oligomer interactions with lipid rafts, a model of neuronal membranes, are not known. Using molecular dynamics simulations, the lipid-binding events, membrane-damage, and protein folding of tau oligomers on various lipid raft surfaces were investigated. Tau oligomers preferred to bind to the boundary domains (Lod) created by the coexisting liquid-ordered (Lo) and liquid-disordered (Ld) domains …

Beyond Health And Animal Rights: A Study In Black Veganism, Wendy J. Rib

USF Tampa Graduate Theses and Dissertations

Veganism, or the avoidance of animal products, has been recognized by nutritionists and food scientists as a lifestyle choice associated with good health and lower prevalence of diabetes, obesity, hypertension, and heart disease. However, the choice to eschew all animal products is frequently more than just a diet. Many people practice veganism as part of a larger reformative social movement, seeking permanent change in food structures, advancing policies in animal welfare and transforming their everyday lives in the quest for cultural acceptance. Although the number of people who identify as vegans appears to be growing, it is often assumed that …

Reprogramming Of Pancreatic Adenocarcinoma Immunosurveillance By A Microbial Probiotic Siderophore, Mehdi Chaib, Bilal B. Hafeez, Hassan Mandil, Deidre Daria, Ajeeth K. Pingili, Sonam Kumari, Mohammed Sikander, Vivek K. Kashyap, Emmanuel Anning, Manish Tripathi, Sheema Khan, Stephen Behrman, Murali M. Yallapu, Meena Jaggi, Subhash C. Chauhan

School of Medicine Publications

There is increasing evidence suggesting the role of microbiome alterations in relation to pancreatic adenocarcinoma and tumor immune functionality. However, molecular mechanisms of the interplay between microbiome signatures and/or their metabolites in pancreatic tumor immunosurveillance are not well understood. We have identified that a probiotic strain (Lactobacillus casei) derived siderophore (ferrichrome) efficiently reprograms tumor-associated macrophages (TAMs) and increases CD8 + T cell infiltration into tumors that paralleled a marked reduction in tumor burden in a syngeneic mouse model of pancreatic cancer. Interestingly, this altered immune response improved anti-PD-L1 therapy that suggests promise of a novel combination (ferrichrome and …

The Mid‑Pleistocene Transition: A Delayed Response To An Increasing Positive Feedback?, Anne Willem Omta, Peter Thomas

Faculty Scholarship

Glacial–interglacial cycles constitute large natural variations in Earth’s climate. The Mid-Pleistocene Transition (MPT) marks a shift of the dominant periodicity of these climate cycles from ∼40 to ∼100 kyr. Recently, it has been suggested that this shift resulted from a gradual increase in the internal period (or equivalently, a decrease in the natural frequency) of the system. As a result, the system would then have locked to ever higher multiples of the external forcing period. We find that the internal period is sensitive to the strength of positive feedbacks in the climate system. Using a carbon cycle model in which …
