Background: Numerous studies have demonstrated the efficacy of creatine supplementation for improvements in exercise performance. Few studies, however, have examined the effects of phosphocreatine supplementation on exercise performance. Furthermore, while polyphenols have antioxidant and anti-inflammatory properties, little is known regarding the influence of polyphenol supplementation on muscular strength, power, and endurance. Thus, the purpose of the present study was to compare the effects of 28 days of supplementation with phosphocreatine disodium salts plus blueberry extract (PCDSB), creatine monohydrate (CM), and placebo on measures of muscular strength, power, and endurance.

Methods: Thirty-three men were randomly assigned to consume either PCDSB, CM, …

Terrestrial Ecological Risk Analysis Via Dietary Exposure At Uranium Mine Sites In The Grand Canyon Watershed (Arizona, Usa), Jo Ellen Hinck, Danielle Cleveland, Bradley E. Sample

United States Geological Survey: Staff Publications

The U.S. Department of the Interior recently included uranium (U) on a list of mineral commodities that are considered critical to economic and national security. The uses of U for commercial and residential energy production, defense applications, medical device technologies, and energy generation for space vehicles and satellites are known, but the environmental impacts of uranium extraction are not always well quantified. We conducted a screening-level ecological risk analysis based on exposure to miningrelated elements via diets and incidental soil ingestion for terrestrial biota to provide context to chemical characterization and exposures at breccia pipe U mines in northern Arizona. …

Metabarcoding Assays For The Detection Of Freshwater Mussels (Unionida) With Environmental Dna, Katy E. Klymus, Catherine A. Richter, Nathan Thompson, Jo Ellen Hinck, Jess W. Jones

United States Geological Survey: Staff Publications

Freshwater mussels of the order Unionida are a widely distributed taxon that are important in maintaining freshwater ecosystems and are also highly imperiled throughout the world. Monitoring of mussel populations with environmental DNA (eDNA) is an attractive alternative to traditional methods because it is noninvasive and requires less labor and taxonomic knowledge from field personnel. We developed eDNA metabarcoding assays specific to freshwater mussels and tested them at six sites in the Clinch River, located in the southeastern United States. Our objective was to determine the utility of eDNA metabarcoding for future monitoring of mussel populations and restoration efforts in …

Detection Of Two Dissimilar Chronic Wasting Disease Isolates In Two Captive Rocky Mountain Elk (Cervus Canadensis) Herds: Two Distinctive Chronic Wasting Disease Isolates Identified In Captive Elk, Tracy A. Nichols, Eric M. Nicholson, Yihui Liu, Wanyin Tao, Terry R. Spraker, Michael Lavelle, Justin W. Fischer, Qingzhong Kong, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Chronic wasting disease (CWD) continues to spread in both wild and captive cervid herds in North America and has now been identified in wild reindeer and moose in Norway, Finland and Sweden. There is limited knowledge about the variety and characteristics of isolates or strains of CWD that exist in the landscape and their implications on wild and captive cervid herds. In this study, we evaluated brain samples from two captive elk herds that had differing prevalence, history and timelines of CWD incidence. Site 1 had a 16-year history of CWD with a consistently low prevalence between 5% and 10%. …

Environmental Dna For Conservation, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Biodiversity must be documented before it can be conserved. However, it may be difficult to document species with few individuals (Thompson, 2013; Goldberg et al., 2016), thus it requires a multitude of tools to detect species that occur in low numbers or are elusive (see the various chapters in this volume). One tool that has become useful for conservation efforts utilizes environmental DNA, which is DNA shed into the environment by organisms (eDNA; Taberlet et al., 2018). Typically this involves taking environmental samples such as soil, water, air, or using biological surrogates for sampling biodiversity (e.g. leeches, sponges, carrion flies, …

Allometric Regression Of Snake Body Length From Head Image Measurements, Shane R. Siers

United States Department of Agriculture Wildlife Services: Staff Publications

As in many fields of wildlife research and management, camera devices and photogrammetry have become an integral part of the toolkit for exploring otherwise‐unseen aspects of the biology, behavior, and control of the invasive brown treesnake (Boiga irregularis) on Guam. Because brown treesnakes are cryptic and nocturnal, and nearly all aspects of their ecology are influenced by snake size, methods are needed to estimate snake size from images captured by infrared wildlife cameras. Unfortunately, it is difficult to capture images of an entire snake’s length at a controlled distance from a simple camera setup. Here, I describe the …

Increased Abundance Of The Common Raven Within The Ranges Of Greater And Gunnison Sage-Grouse: Influence Of Anthropogenic Subsidies And Fire, Jonathan B. Dinkins, Lindsey R. Perry, Jeffrey L. Beck, Jimmy D. Taylor

United States Department of Agriculture Wildlife Services: Staff Publications

The common raven (Corvus corax; raven) is native to North America and has increased in abundance, especially throughout western North America, during the last century. Human subsidies have facilitated raven dispersal into less suitable habitats and enabled these populations to maintain higher annual survival and reproduction. Concomitantly, overabundant raven populations are impacting other native at-risk species such as the greater sage-grouse (Centrocercus urophasianus) and potentially the Gunnison sage-grouse (C. minimus). Using Breeding Bird Survey data from 1995–2014, we evaluated raven count data to quantitatively describe changes in abundance and expansion into sagebrush ( …

A Novel Technique To Improve Capture Success Of Common Ravens, Lindsey R. Perry, Terrah M. Owens, Zachary T. Slick, Jimmy Taylor, Jonathan B. Dinkins

United States Department of Agriculture Wildlife Services: Staff Publications

Traditional trapping techniques for common ravens (Corvus corax; raven) require significant effort, often produce low capture rates, and cannot be used in some situations. We designed a 3-m noose pole to secure ravens from nocturnal roost locations while using a strobe spotlight to temporarily disorient them. We collected measures of trapping efficiency and contrasted them with padded leghold traps also used in the study. We effectively implemented our noose pole method in July and August of 2018, 2019, and 2020 in the Baker and Cow Lakes sage-grouse (Centrocercus urophasianus) Priority Areas of Conservation in eastern Oregon, USA, which yielded trapping …

Beyond Plea Bargaining: A Theory Of Criminal Settlement, Richard Lorren Jolly, J.J. Prescott

Articles

Settlement is a term rarely used in criminal law. Instead, people speak almost exclusively of plea bargaining—i.e., enforceable agreements in which a defendant promises to plead guilty in exchange for a prosecutor’s promise to seek leniency in charging or at sentencing. But a traditional plea agreement is just the most visible instance of a much broader class of possible criminal settlement agreements. In terms of their fundamentals, criminal settlements are indistinguishable from their civil counterparts: through either an atomized or comprehensive bargain, parties exchange what they have for what they want, advancing their respective interests in cost minimization, risk mitigation, …

The Effect Of Physical Activity On The Mental Health Of Pre-Nursing Students And Undergraduate Student Nurses, Larinda J. Fandrich

DNP Research Projects

Abstract

Mental health concerns are on the rise among the college-aged student. College students face a great deal of stress, which can lead to depression and anxiety. Nursing students, as a sub-group of college students, are under even greater stress related to rigorous course work and the responsibility of caring for other people, which can lead to greater depression and anxiety. This study aimed to determine what effect, if any, physical activity has on depression and anxiety scores using the PHQ-9 and GAD-7 instruments in pre-nursing and nursing students. In this study, physical activity is defined as is “any bodily …

Ethical Price For Essential Pharmaceuticals?, Sang T. Truong

Student Research

Azidothymidine or AZT is an antiretroviral medication used to prevent and treat HIV/AIDS. Nowadays, AZT remains to be the primary active drug that can elongate the life of infected patients. Without treatment, patients can live for 5 to 10 years after infected. With the treatment, their life expectancy approaches the norm.

However, it is important to note that AZT is a life-saver for HIV patients only if they can afford it. An HIV patient needs to spend about $17,000 for AZT every year until the end of his life. Therefore, the estimated lifetime cost of HIV will be $600,000. This …

Deep Tracks: Album Cuts That Help Define The Essential Scalia, Gary S. Lawson

Faculty Scholarship

Jeff Sutton and Ed Whelan have collected some of Justice Scalia’s “greatest hits” in a volume entitled The Essential Scalia: On the Constitution, the Courts, and the Rule of Law. The book is an excellent introduction to the jurisprudential thought and literary style of one of the most influential legal thinkers—and legal writers—in modern times. As with any “greatest hits” compilation, however, there are inevitably going to be key “album cuts” for which there will not be space. This essay seeks to supplement Sutton and Whelan’s invaluable efforts by surveying three of those “deep tracks” that shed particular light on …

If Not Otitis Externa...Then What?, Elizabeth A. Flasch, Sadia Ansari, Timothy Martin

College of Nursing Faculty Research and Publications

Ear pain is one of the most common presentations in urgent care, especially among pediatric patients. Further, acute otitis media (AOM) is the most common condition for which antibacterial agents are prescribed for children in the United States. Clinician visits make up 634 per 100 children during 2005-2006. It is imperative that clinicians differentiate AOM from new onset of otorrhea not due to acute otitis externa (AOE), the most common diagnoses made by clinicians with regional variations based on age and geography.1

The majority of AOE-related visits occur during the summer months (June through August); visits occur most commonly in …

Physiological Impacts Of Lampricides On Invasive Sea Lamprey (Petromyzon Marinus) And Non-Target Fishes, Razvan, Adrian Ionescu

Theses and Dissertations (Comprehensive)

Parasitic sea lamprey (Petromyzon marinus) ingest large quantities of blood from fishes using their oral disc and rasping tongue, most often killing the host. In the early 1900s, sea lamprey invaded the Laurentian Great Lakes, decimating sport, commercial and culturally significant fisheries. Since the early 1960s, chemical control using the lampricides 3- trifluoromethyl-4-nitrophenol (TFM) and niclosamide have helped to reduce sea lamprey populations by 90%. Lampricides are applied to larval lamprey nursery streams targeting many generations of lamprey at once. However, there is concern about the potential adverse effects of lampricides on other fishes, particularly vulnerable lake sturgeon (Acipenser fulvescens) …

Neighbouring Horizons: Migration, Squatting, And Citizenship In São Paulo, Diana Zacca Thomaz

Theses and Dissertations (Comprehensive)

This dissertation examines the shared struggles and political horizons of citizens and non-citizens living together in squatted buildings in central São Paulo, Brazil. Building on six months of ethnographic fieldwork, it focuses on the coalition forged between the MSTC (Movimento Sem Teto do Centro, i.e. Central São Paulo Roofless Movement) and international migrants and asylum-seekers who have taken up residence in the movement’s squats. This dissertation argues that the problem of political subjectivity and belonging at the urban margins is deeply shaped by the struggles for adequate housing. Further, that looking at the divergent aspirations and claims-making of …

Enhancing Harvester Safety And Traditional Food Access Through Participatory Mapping With The Ka’A’Gee Tu First Nation Of Kakisa, Northwest Territories, Neomi Jayaratne

Theses and Dissertations (Comprehensive)

Northern Canada has struggled with various systemic challenges based on Eurocentric ideologies, policies, and practices. A major challenge Indigenous communities face North of the 60^th parallel is their food security and sovereignty. Inuit, First Nation and Métis populations across the North experience 5 to 6 times higher levels of food insecurity compared to the National average (Food Secure Canada, 2020). These communities face concentrated levels of food system issues, which connect to other factors, such as, health and wellness, the supply chain of market foods, governance, a shift away from traditional foods, and the impacts of climate change. Climate …

Sucrose Solution Access Influences Intake Value In Rats, Adam Celejewski

Theses and Dissertations (Comprehensive)

Previous work has shown that non-deprived rats’ intake of a 4% sucrose solution increases over 24 h access periods if it is provided every 3 or 4 days (E3D or E4D) relative to every day (ED; (Eikelboom & Hewitt, 2016)⁠. Once these access-intake differences are established, they can be enduring, even if all rats are shifted to a common access schedule. Do changes in value accompany these access-induced solution intake changes? Three approaches were applied to test for access-induced value changes. First, following extended 24 h E3D (12 exposures) or ED (36 days) access to a flavoured 4% (Experiment 1) …

Breaking The Chain – The Role Of Intersexual Genetic Correlations In Sexual Dimorphism And The Consequences And Limits Of Their Evolution, Matthew Ma Maoloni, Tara Newman, Tristan Af Long Dr.

Theses and Dissertations (Comprehensive)

In many sexually reproducing species, males and females often differ in countless ways beyond their primary sexual organs. This phenomenon is known as sexual dimorphism, and it is generally considered to be an adaptive response to differences in the selection pressures experienced by males and females. Despite the advantages associated with sexual dimorphism, it does not evolve completely unhindered – there are plenty of biological effects that can limit the extent and rate of divergence between the sexes. This research project focusses on the potential role of the intersexual genetic correlation (r_mf­) – which describes the …

Copper Binding To Fish Gill Cell Lines: Towards Determination Of Biotic Ligand Model Parameters, Samantha Kliewer

Theses and Dissertations (Comprehensive)

In aquatic environments, copper is a potentially toxic element that is also an essential nutrient, aiding in the growth and development of all aerobic organisms. In small quantities, copper acts as a micronutrient, playing a large role in many enzymatic reactions, however, at increased concentrations, copper is a potential aquatic pollutant that can cause metal toxicity. The biotic ligand model (BLM) is a useful tool that is often used for metals risk assessment and helps to establish protective water criteria guidelines. Previously, the BLM has been used to model metal complexation directly at the biotic ligand (e.g., gill) for …

Abstract

DEVELOPING POPULATION CONTROL STRATEGIES FOR WILD BOAR MANAGEMENT IN CANADA

Amanda Wong Advisor: Scott Slocombe

Wilfrid Laurier University 2020

Canada’s landscape faces major threats from the growing wild boar (Sus scrofa) population, whose current presence predominantly threatens the Prairie provinces. Globally it has become apparent that wild boars are robust animals with high reproductive rates and destructive behaviours in both their native and non-native ranges. This paper analyzes wild boar management strategies that have been conducted around the world to identify the most effective tools, and those that were unsuccessful. The wild boars in Canada are hybridized …

Advertainers And Their Audience: Power Relations And Promotionalism In Hobbykidstv, Sherry Morley

Theses and Dissertations (Comprehensive)

YouTube presents itself as an egalitarian platform that promotes creativity and free expression among its creators, and that breaks with legacy media models. Among the mass of YouTube creators are top-earning “family influencers” who produce videos in which parents and their children are portrayed as leisurely playing and merely having fun. Behind the scenes, however, family influencer channels are capitalist, structured, and highly profitable. This thesis offers a case study of one family influencer channel, HobbyKidsTV. Exploring concepts of labour, leisure, agency, and consumer subjectivity, I de-naturalize HobbyKidsTV through a multimodal critical discourse analysis. Surfacing the power relations within HobbyKidsTV, …

Dsrna Conjugated Phytoglycogen Nanoparticles As An Innate Immune Stimulant To Prevent Viral Infections In Rainbow Trout And Atlantic Salmon, Kayla Samms

Theses and Dissertations (Comprehensive)

Salmonids are one of the world’s most farmed fish species. These aquatic vertebrate species rely heavily on their innate immune responses to defend themselves against invading pathogens. Although commercial vaccines are available against some viral and bacterial pathogens affecting salmonids, their protective efficacy is variable. Using a prophylactic inducer of local and systemic innate immune responses could have significant implications in salmonid aquaculture. A potent inducer of the innate immune response in fish is double-stranded RNA (dsRNA), a molecule that all viruses make during their replicative cycle. Polyinosinic:polycytidylic acid (polyI:C) is a synthetic dsRNA commonly used to induce type I …

Binary Black Widow Optimization Algorithm For Feature Selection Problems, Ahmed Al-Saedi

Theses and Dissertations (Comprehensive)

This thesis addresses feature selection (FS) problems, which is a primary stage in data mining. FS is a significant pre-processing stage to enhance the performance of the process with regards to computation cost and accuracy to offer a better comprehension of stored data by removing the unnecessary and irrelevant features from the basic dataset. However, because of the size of the problem, FS is known to be very challenging and has been classified as an NP-hard problem. Traditional methods can only be used to solve small problems. Therefore, metaheuristic algorithms (MAs) are becoming powerful methods for addressing the FS problems. …

Characterization Of Micronutrient Dependent Growth By Several Temperate Freshwater Phytoplankton, Purnank Shah

Theses and Dissertations (Comprehensive)

Harmful algal blooms (HABs) are a growing problem in many freshwater waterbodies in Canada and around the world. HABs have wide-ranging impacts to ecosystems and economies. Since the 1970s, the primary focus of policies with respect to curbing HABs has been to lowering the inputs of P into waters. However, reports of HABs continue to increase even with all these P-removing policies in place. Some jurisdictions have chosen to focus on N-removal instead or in conjunction with P-removal to help with HABs. However, because some cyanobacteria have the ability to fix atmospheric N₂,N-removal might only lead to the …

Composition And Homology In The Taxonomic Classification Of Escherichia Coli, Tanya Irani

Theses and Dissertations (Comprehensive)

As new techniques have been introduced, specifically the possibility of complete genome sequencing, better methods of defining bacterial species have also been proposed. One of the most recently proposed methods, using bioinformatic techniques, is to calculate the average nucleotide identity (ANI) between the homologous genome segments of different isolates. Another method for species discrimination that has been tested successfully is the similarity of DNA compositional signatures. However, in a recent update, DNA signatures split the available Escherichia coli complete genomes into three groups. To check if this result was consistent with such genomes belonging to different species, we tested methods …

To Like Or To Want? Exploring The Psychobiological Processes Of Human Food Reward, Angela Mastroianni

Theses and Dissertations (Comprehensive)

The Incentive Salience Theory (IST; Berridge and Robinson, 1998; 2016) has shown that wanting (craving) and liking (affective) processes can affect eating behaviour differently in animals. These processes often correlate but can dissociate (change differently) under certain circumstances as they rely on separate neural mechanisms (Berridge, 1996). More recently, work has been testing the IST in people by comparing broad food categories (Finlayson et al. 2007a; 2008). The results have been inconsistent, sparking debate about the theory's value for studying human feeding (Havermans, 2011; 2012).

This dissertation's aim was to explore if IST wanting and liking are independent processes controlling …
