A Comparison Of Drone Imagery And Groundbased Methods For Estimating The Extent Of Habitat Destruction By Lesser Snow Geese (Anser Caerulescens Caerulescens) In La Pérouse Bay, Andrew F. Barnas, Brian J. Darby, Gregory S. Vandeberg, Robert F. Rockwell, Susan N. Ellis-Felege

Biology Faculty Publications

Lesser snow goose (Anser caerulescens caerulescens) populations have dramatically altered vegetation communities through increased foraging pressure. In remote regions, regular habitat assessments are logistically challenging and time consuming. Drones are increasingly being used by ecologists to conduct habitat assessments, but reliance on georeferenced data as ground truth may not always be feasible. We estimated goose habitat degradation using photointerpretation of drone imagery and compared estimates to those made with ground-based linear transects. In July 2016, we surveyed five study plots in La Pérouse Bay, Manitoba, to evaluate the effectiveness of a fixed-wing drone with simple Red Green Blue …

Improving Student Attitudes Toward Discussion Boards Using A Brief Motivational Intervention, Virginia Clinton, Alison E. Kelly

Education, Health & Behavior Studies Faculty Publications

Discussion boards are tools to afford student interaction and engagement in online courses, but students often have negative attitudes toward discussion boards. The purpose of this study was to determine whether an intervention informing students of the usefulness of online discussion boards affected their attitudes toward discussion boards. The instructor randomly assigned students (N = 65) to view a video and answer an essay question on either the benefits of discussion boards (treatment) or how discussion boards were graded (control). Students in the treatment condition indicated discussion boards as being more useful than did students in the control condition, p …

The Prey Drive Model Of Sexual Violence, Tiffany Dawn Russell

Theses and Dissertations

The current project introduced prey drive theory, a new conceptualization of human violence perpetration adapted from canine training and breeding literature. As with canines, prey drive theory conceptualizes human aggression as a manifestation of genetically predisposed dominance and competitiveness. To evaluate the concept of human prey drive, the current study developed a prey drive model of sexual violence that was tested within a community sample of men (N = 662). Four latent trait clusters formed the foundation of the model: sexualized prey dominance, sexualized prey pursuit, antagonistic preparedness, and malevolent personality. A new scale, the Masculine Dominance Index, was …

Molecular Phylogeny Provides New Insights On The Taxonomy And Composition Of Lyperosomum Looss, 1899 (Digenea, Dicrocoeliidae) And Related Genera, Joanna Hildebrand, Ewa Pyrka, Jiljí Sitko, Witold Jeżewski, Grzegorz Zaleśny, Vasyl V. Tkach, Zdzisław Laskowski

Biology Faculty Publications

Lyperosomum Looss, 1899 is one of the largest genera of the Dicrocoeliidae and is one of the best examples of the systematic complexity and taxonomic instability within this family. We present the molecular analyses based on novel sequences of nuclear and mitochondrial genes obtained from 56 isolates of adult flukes and larval stages of dicrocoeliids belonging to Lyperosomum, Skrjabinus, Zonorchis as well as previously available sequence data. According to obtained results we propose to return Zonorchis clathratus and Z. petiolatus into Lyperosomum, and to recognize L. alagesi as a synonym of L. petiolatum. Our study shows that L. petiolatum commonly …

Understanding The Molecular And Cellular Functions Of Odd-Skipped Related 1 In Outflow Tract Development, Menglan Xiang

Theses and Dissertations

The cardiac outflow tract (OFT) is a transient conduit that connects the embryonic heart chambers to the vascular network. Transcription factor Osr1 promotes the proliferation and cell cycle progression of second heart field (SHF), an essential cell population that contribute to the developing OFT. In this study, we investigated the role of Osr1 in OFT development on cellular and molecular levels using a systems biology approach. We observed OFT rotation and elongation defects, as well as double-outlet right ventricle and overriding aorta as a result of SHF-specific deletion of Osr1. Using genetic inducible fate mapping, we showed that Osr1-expressing SHF …

Students summarize key components of an empirical study in a one-page figure. An assessment rubric is also included that can be easily modified by instructors to meet their specific needs. Assessment data from two institutions reveal that students …

Schlafen 3 Knockout Mice Display Gender-Specific Differences In Weight Gain, Food Efficiency, And Expression Of Markers Of Intestinal Epithelial Differentiation, Metabolism, And Immune Cell Function, Emilie E. Vomhof-Dekrey, Jun Lee, Jack Lansing, Chris Brown, Diane Darland, Marc D. Basson

Biology Faculty Publications

Self-renewal and differentiation are essential for intestinal epithelium absorptive functioning and adaptation to pathological states such as short gut syndrome, ulcers, and inflammatory bowel disease. The rodent Slfn3 and its human analog Slfn12 are critical in regulating intestinal epithelial differentiation. We sought to characterize intestinal function in Slfn3 knockout (KO) mice. Male and female pair-fed Slfn3KO mice gained less weight with decreased food efficiency than wild type (WT) mice, with more pronounced effects in females. RNA sequencing performed on intestinal mucosa of Slfn3KO and WT mice showed gene ontology decreases in cell adhesion molecule signaling, tumor necrosis factor receptor binding, …

Embodied Truths: How Dynamic Gestures And Speech Contribute To Mathematical Proof Practices, Elizabeth L. Pier, Candace Walkington, Virginia Clinton, Rebecca Boncoddo, Caroline Williams-Pierce, Martha W. Alibali, Mitchell J. Nathan

Education, Health & Behavior Studies Faculty Publications

Grounded and embodied theories of cognition suggest that both language and the body play crucial roles in grounding higher-order thought. This paper investigates how particular forms of speech and gesture function together to support abstract thought in mathematical proof construction. We use computerized text analysis software to evaluate how speech patterns support valid proof construction for two different tasks, and we use gesture analysis to investigate how dynamic gestures—those gestures that depict and transform mathematical objects—further support proof practices above and beyond speech patterns. We also evaluate the degree to which speech and gesture convey distinct information about mathematical reasoning …

Modeling Atmosphere-Ocean Radiative Transfer: A Pace Mission Perspective, Xiaodong Zhang, Jacek Chowdhary, Peng-Wang Zhai, Emmanuel Boss, Heidi Dierssen, Robert Frouin, Amir Ibrahim, Zhongping Lee, Lorraine A. Remer, Michael Twardowski, Feng Xu, Matteo Ottaviani, William Reed Espinosa, Didier Ramon

Earth System Science and Policy Faculty Publications

The research frontiers of radiative transfer (RT) in coupled atmosphere-ocean systems are explored to enable new science and specifically to support the upcoming Plankton, Aerosol, Cloud ocean Ecosystem (PACE) satellite mission. Given (i) the multitude of atmospheric and oceanic constituents at any given moment that each exhibits a large variety of physical and chemical properties and (ii) the diversity of light-matter interactions (scattering, absorption, and emission), tackling all outstanding RT aspects related to interpreting and/or simulating light reflected by atmosphere-ocean systems becomes impossible. Instead, we focus on both theoretical and experimental studies of RT topics important to the science threshold …

The Regulatory Control Of Cebpa Enhancers And Silencers In The Myeloid And Red-Blood Cell Lineages, Andrea Repele, Shawn Krueger, Tapas Bhattacharyya, Michelle Y. Tuineau, Manu

Biology Faculty Publications

Cebpa encodes a transcription factor (TF) that plays an instructive role in the development of multiple myeloid lineages. The expression of Cebpa itself is finely modulated, as Cebpa is expressed at high and intermediate levels in neutrophils and macrophages respectively and downregulated in non-myeloid lineages. The cis-regulatory logic underlying the lineage-specific modulation of Cebpa’s expression level is yet to be fully characterized. Previously, we had identified 6 new cis-regulatory modules (CRMs) in a 78kb region surrounding Cebpa. We had also inferred the TFs that regulate each CRM by fitting a sequence-based thermodynamic model to a comprehensive …

Bird Species And Abundances In Fruit Crops And Implications For Bird Management, Melissa B. Hanney, Jason R. Boulanger, Paul D. Curtis, Rachael A. Eaton, Benjamin C. Hawes, Deanna K. Leigh, Cody A. Rossetti, Karen M. M. Sttensma, Catherine A. Lindell

Biology Faculty Publications

Fruit consumption by birds is a costly problem in North America, yet basic information about the species and abundance of fruit-eating birds in fruit crops, and factors that influence abundance, are lacking. We conducted a study of fruit-eating birds in 'Honeycrisp' apples, blueberries, grapes, and sweet cherries in Michigan, New York, and the Pacific Northwest in 2012 and 2013. We documented the most frequently observed fruit-eating birds in each crop across our study regions, and used fruit-consumption data to identify bird species for each crop and region that have a great impact via fruit consumption. We found that American Robins …

Outcomes In Treatment Of Major Depressive Disorder: Pharmacogenomic Testing Vs. Treatment As Usual, Zachary Horoshak

Physician Assistant Scholarly Project Papers

The goal of this systematic literature review is to evaluate the efficacy and cost effectiveness of pharmacogenomic testing (PGx) versus treatment as usual (TAU) in the treatment of major depressive disorder (MDD). According to Huang & Lin (2015), MDD is characterized by multiple signs and symptoms consisting of mood, vegetative, cognitive, and even psychotic behaviors that may cause substantial impairment in the functioning and quality of life in an affected individual. This literature review consisted of articles found in PubMed, Cochrane, and PsychINFO which were extensively reviewed. Articles prior to 2008 were excluded due to the ever-changing landscape of PGx …

Comparison Of Rivaroxaban And Warfarin In The Prevention Of Recurrent Venous Thromboembolism, Philip Joel Heiden

Physician Assistant Scholarly Project Papers

The purpose of this systematic literature review is to determine the efficacy and safety of rivaroxaban (Xarelto) compared to warfarin (Coumadin), for the long term prophylaxis of recurrent venous thromboembolism (VTE). Rivaroxaban was chosen as the primary representative of factor Xa inhibitors because of its simplistic once a day dosing regimen. The PubMed database was extensively searched, using a variety of key terms, from September 10 to November 30, 2018. Works chosen include propensity-matched cohorts, retrospective studies, systematic reviews, and meta-analyses. All of which were published within the last 10 years; sources dated prior to 10 years were excluded. Studies …

The Impact Of Shift Work On Health And Wellbeing, Stephanie Gagelin

Physician Assistant Scholarly Project Papers

Many of today’s industries require workers to perform shift work (typically during 1600-0700). If workers are awake during this time period, circadian misalignment occurs. This scholarly project uses research studies and meta-analyses to provide information about increased health risks associated with circadian misalignment, focusing particularly on the categories of glucose metabolism, cardiovascular system, carcinogenesis, and mental health and acuity. Shift work has been found to increase BMI and waist circumference of employees, as well as increase blood glucose levels to “prediabetic” levels in previously euglycemic individuals. Shift work has been proven to increase high-sensitivity C-reactive protein (hs-CRP), an acute phase …
