Non-Linear Responses Of Glaciated Prairie Wetlands To Climate Warming, W. Carter Johnson, Brett Werner, Glenn R. Guntenspergen

United States Geological Survey: Staff Publications

The response of ecosystems to climate warming is likely to include threshold events when small changes in key environmental drivers produce large changes in an ecosystem. Wetlands of the Prairie Pothole Region (PPR) are especially sensitive to climate variability, yet the possibility that functional changes may occur more rapidly with warming than expected has not been examined or modeled. The productivity and biodiversity of these wetlands are strongly controlled by the speed and completeness of a vegetation cover cycle driven by the wet and dry extremes of climate. Two thresholds involving duration and depth of standing water must be exceeded …

Fibronectin Deposition Participates In Extracellular Matrix Assembly And Vascular Morphogenesis, Abigail Hielscher, Kim Ellis, Connie Qiu, Josh Porterfield, Sharon Gerecht

PCOM Scholarly Works

The extracellular matrix (ECM) has been demonstrated to facilitate angiogenesis. In particular, fibronectin has been documented to activate endothelial cells, resulting in their transition from a quiescent state to an active state in which the cells exhibit enhanced migration and proliferation. The goal of this study is to examine the role of polymerized fibronectin during vascular tubulogenesis using a 3 dimensional (3D) cell-derived de-cellularized matrix. A fibronectin-rich 3D de-cellularized ECM was used as a scaffold to study vascular morphogenesis of endothelial cells (ECs). Confocal analyses of several matrix proteins reveal high intra- and extra-cellular deposition of fibronectin in formed vascular …

When Enough Is Enough: The Impact Of Parental Involvement In Children's Participation In Organized Sports, Dorothy K. Hollins

University Honors Theses

In the United States, organized sports for children and youth play a key role in our country’s culture. Child participation in organized youth sports begins as young as the age of 5 and continues on to 18 years of age. Youth participation in athletics is premised upon the socially accepted notion that participation in competitive sports builds character, which in turn helps children learn valuable life lessons. However, recent studies have shown that youth athletics provides an environment for adults to become overly emotionally invested in their children’s athletic endeavors. This thesis examines varying levels of parental involvement in their …

#Blacklivesmatter: This Generation's Civil Rights Movement, Tanika Siscoe

University Honors Theses

Do Black Lives Matter or do All Lives Matter? That question has been the cause of many debates and conversations across America recently. The All Lives Matter response was created to criticize the Black Lives Matter Movement and operates under the assumption that the movement isn’t needed in America because it is a post racial society. This thesis reviews race theories, racial formation in the United States and racist ideology in the pre- and post-Civil Rights era in order to show why the Black Lives Matter Movement is needed. It looks at the influence colorblindness has on the United States …

Libguides Two Ways: Teaching Information Literacy In And Out Of The Classroom, Lucinda Rush

Libraries Faculty & Staff Publications

Librarians at Old Dominion University (ODU) Libraries use the LibGuides platform in a creative way to meet immediate, practical needs. Traditionally, we have offered two types of information literacy tutorials. The first is a lengthy, module-based tutorial and is used in our information literacy-designated courses to cover skills in-depth and which students must complete over the course of a semester. The second is a short tutorial designed to give students an introduction or a refresher covering basic research skills, information literacy concepts, and library services.

Prior to migrating to a new web platform, ODU Libraries hosted short click-through tutorials on …

Bordering The Constitution, Constituting The Border, Efrat Arbel

Osgoode Hall Law Journal

It is an established principle in Canadian law that refugees present at or within Canada’s borders are entitled to basic constitutional protection. Where precisely these borders lie, however, is far from clear. In this article, I examine the Canadian border as a site at which to study the constitutional entitlements of refugees. Through an analysis of the Multiple Borders Strategy (MBS)--a broad strategy that re-charts Canada’s borders for the purposes of enhanced migration regulation--I point to a basic tension at play in the border as site. I argue that the MBS imagines and enacts the border in two fundamentally different …

Reconsidering Copyright’S Constitutionality, Graham J. Reynolds

Osgoode Hall Law Journal

In 1996, in Compagnie Générale des Établissements Michelin – Michelin & Cie v National Automobile, Aerospace, Transportation and General Workers Union of Canada (CAW-Canada) [Michelin], Justice Teitelbaum of the Federal Court (Trial Division) held both that specific provisions of the Copyright Act did not infringe the right to freedom of expression as protected under the Canadian Charter of Rights and Freedoms and that, even if they did, these provisions could be justified under s 1 of the Charter. Since Michelin, these conclusions have been treated by Canadian courts as settled. The purpose of this paper is to challenge these conclusions …

Spatial Distribution And Air-Water Exchange Of Organic Flame Retardents In The Lower Great Lakes, Carrie A. Mcdonough, Gavino Puggioni, Paul A. Helm, Derek Muir, Rainer Lohmann

Graduate School of Oceanography Faculty Publications

Organic flame retardants (OFRs) such as polybrominated diphenyl ethers (PBDEs) and novel halogenated flame retardants (NHFRs) are ubiquitous, persistent, and bioaccumulative contaminants that have been used in consumer goods to slow combustion. In this study, polyethylene passive samplers (PEs) were deployed throughout the lower Great Lakes (Lake Erie and Lake Ontario) to measure OFRs in air and water, calculate air–water exchange fluxes, and investigate spatial trends. Dissolved Σ₁₂BDE was greatest in Lake Ontario near Toronto (18 pg/L), whereas gaseous Σ₁₂BDE was greatest on the southern shoreline of Lake Erie (11 pg/m³). NHFRs were generally …

Anaplasma Marginale Actively Modulates Vacuolar Maturation During Intracellular Infection Of Its Tick Vector, Dermacentor Andersoni, Foregivemore Magunda, Chelsea Wright Thompson, David A. Schneider, Susan M. Noh

Biological Sciences Faculty Publications

ABSTRACT Tick-borne transmission of bacterial pathogens in the order Rickettsiales is responsible for diverse infectious diseases, many of them severe, in humans and animals. Transmission dynamics differ among these pathogens and are reflected in the pathogen-vector interaction. Anaplasma marginale has been shown to establish and maintain infectivity within Dermacentor spp. for weeks to months while escaping the complex network of vacuolar peptidases that are responsible for digestion ofthe tick blood meal. How this prolonged maintenance of infectivity in a potentially hostile environment is achieved has been unknown. Using the natural vector Dermacentor andersoni, we demonstrated that A. marginale …

Biogas From Cattle Slaughterhouse Waste: Energy Recovery Towards An Energy Self-Sufficient Industry In Ireland, Niamh Power, Aidan Ware

Publications

This study was carried out to assess the energy recovery potential from organic industrial by-products of a cattle slaughtering facility. There are several processes to convert organic material to energy; the technology of interest in this study was anaerobic digestion, the biological conversion of degradable organic material into methane. The scenario was initially confined to a full scale cattle slaughtering facility processing 3.28% of heads slaughtered in Ireland. The methane potential of dissolved air flotation sludge, paunch, soft offal as well as a mixed waste stream (combination of individual waste streams) was determined through a series of biochemical methane …

What Is The Effect Of Mandatory Pasteurisation On The Biogas Transformation Of Solid Slaughterhouse Wastes?, Niamh Power, Aidan Ware

Publications

The effect of mandatory pasteurisation on Category 3 offals, according to the Animal By-Products Regulation (ABPR 1069/2009/EC), was determined using Biochemical Methane Potential (BMP) assays as well as kinetic and statistical analysis. Pasteurised and unpasteurised offals sampled from cattle, pig and chicken slaughterhouses were characterised and their specific methane yields (SMYs) and their bioavailability was assessed. The resultant SMYs were high (465–650 mLCH₄ gVS⁻¹) with no statistically significant increase in methane production identified due to pasteurisation. However, the kinetics of the biogas transformation processes highlighted increased bioavailability of the organics due to pasteurisation. This was brought to …

Characterization Of Piezoelectric Device For Implanted Pacemaker Energy Harvesting, Sunny Jay, Manuel Caballero, William Quinn, John Barrett, Martin Hill

Conference Papers

Novel implanted cardiac pacemakers that are powered by energy harvesters driven by the cardiac motion and have a 40 year lifetime are currently under development. To satisfy space constraints and energy requirements of the device, silicon-based MEMS energy harvesters are being developed in the EU project (MANpower). Such MEMS harvesters for vibration frequencies below 50 Hz have not been widely reported. In this paper, an analytical model and a 3D finite element model (FEM) to predict displacement and open circuit voltage, validated through experimental analysis using an off-the-shelf low frequency energy harvester, are presented. The harvester was excited through constant …

This case study analyzes the activities of two major technology firms, Microsoft and Apple, to liberate enormous holdings of trapped cash. The case prompts a discussion of the topic of trapped cash, stakeholder considerations and tools available to manage cash balances held outside the United States. The focus is to examine the strategies available and those selected by Microsoft and Apple to meet or at least appease stakeholder demands …

The Glass Cage: The Gender Pay Gap And Self-Employment In The United States, Leanna Lawter, Tuvana Rua, Jeanine K. Andreassi Ph.D.

New England Journal of Entrepreneurship

Self-employment is often viewed as a more desirable work arrangement than working as an employee for a firm. Women are pushed into self-employment due to organizational factors, such as a shrinking workforce or limited job opportunities, while being attracted to self-employment by the many psychological and social benefits (e.g., independence, flexibility, work-life balance, job satisfaction). Despite more women moving into self-employment, this type of employment still has different financial consequences for men and women. This article investigates whether a pay gap exists for self-employed women after controlling for industry, occupation, and hours worked and seeks to quantify the gender wage …

Then And Now: Across Ten Years Of Arkansas Women In Agriculture, Paige Acklie, Jennie Popp, Donald Johnson, Tamara Walkingstick

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The United States Agricultural Census show that between 2002 and 2012, the number of women farm operators in Arkansas grew 14% (from 19,856 to 22,637). These women operators have made up an increasingly larger percentage of all farm operators in the state (from almost 29% to nearly 33%). There is little published information regarding changes over time in the role of women in agriculture, their challenges, and factors important to their success. While some surveys of farm women have been conducted, these surveys are generally insufficient because data exist only for one point in time. This research uses the first, …

The Effects Of Shade On Primocane Fruiting Blackberries In The Field, Olivia C. Caillouet, Curt C. Rom, Jason Mcafee, Luke Freeman, Heather Friedrich

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Primocane fruiting blackberry production in Arkansas is limited by heat during the flowering and early fruiting season. Shade could be used to delay flowering and fruiting to more favorable growth period. This study was designed to test three levels of shade (0% [control], 30% and 50% shading) applied at three times during the growing season that examined the growth, development, physiology of flowering, and fruiting of ‘Prime-Ark® 45’ blackberries. The seven treatments were as follows: 1) an untreated control (CK), 2) early shade 30% (ES30), mid shade 30% (MS30), 4) late shade 30% (LS30), 5) early shade 50% (ES50), 6) …

Evaluation Of Protein Source At Breakfast On Energy Metabolism, Metabolic Health, And Food Intake: A Pilot Study, Lauren A. Cambias, Brianna L. Neumann, Charlayne Mitchell, Jamie I. Baum

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Over 30% of adults in the U.S. are obese. A primary contributor to obesity is an unhealthy diet related to imbalanced macronutrients. Diets higher in protein (PRO) rather than carbohydrate (CHO) are associated with increased energy expenditure (EE) and reduced food intake. The objective of this pilot study was to determine if protein source at breakfast influences EE in young men (n = 4; ages 18-35). Participants consumed three isocaloric (whey (WP), pea (PP), beef (BP); 275 kcal, 62% PRO, 23% CHO, 15% Fat) drinks in a randomized, crossover design study with a one-week washout period (time between the administration …

Efficiency Of The Nuclease I-Scei In Excising Selectable Marker Genes From The Plant Genome, Elliot E. Pruett, Soumen Nandy, Vibha Srivastava

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Gene stacking is a method used in biotechnology by which multiple genes can be placed at a single genomic site, thereby simplifying plant breeding. In this approach, DNA nucleases are used for excising selectable marker genes (SMG), which are the unneeded components of transgenic plants. The goal of this project is to evaluate the effectiveness of the nuclease I-SceI in excising DNA in plants. Specifically, this study tests heat-inducible I-SceI through the use of a heat-shock promoter (HS) in order to control SMG excision by heat application. The DNA plasmid containing a visual marker gene flanked by I-SceI target sites …
