Turkey Vulture Survival Is Reduced In Areas Of Greater Road Density, Adrián Naveda-Rodríguez, Keith L. Bildstein, David R. Barber, Jean-François Therrien, Michael L. Avery, Bryan M. Kluever, Scott A. Rush, Francisco J. Vilella

United States Department of Agriculture Wildlife Services: Staff Publications

The demography of, and factors that influence these metrics, are largely unknown for most vultures in the Americas. Survivorship of turkey vultures (Cathartes aura) may be influenced by landscape heterogeneity and human disturbance. We quantified the effects of landscape composition (Shannon’s diversity index) and configuration (contagion, edge density, and largest patch index), and human disturbance (road density) on the annual and seasonal survival probabilities of the three North American breeding populations (western, central, and eastern) of turkey vultures that spend the nonbreeding season in the southeastern portion of the Nearctic and the northern Neotropics during a 17-year period. …

United States Department of Agriculture Wildlife Services: Staff Publications

Background Hepatozoon spp. are apicomplexan parasites known to cause musculoskeletal disease in a variety of animals. Two species are known to infect wild and domestic canids in the United States: Hepatozoon canis and H. americanum.

Methods In this study, blood, heart, and/or spleen samples were collected from 278 wild canids (180 coyotes, 93 red foxes, and 5 gray foxes) in the eastern US and tested via PCR for Hepatozoon. Histology slides of heart and skeletal muscle were assessed for Hepatozoon cysts and associated inflammation when fresh tissue was available (n = 96).

Results Hepatozoon spp. were …

A Next-Generation Sequencing Study Of Arthropods In The Diet Of Laysan Teal Anas Laysanensis, Wieteke A. Hothuijzen, Carmen C. Antaky, Elizabeth N. Flint, Jonathan H. Plissner, Coral A. Wolf, Holly P. Jones

United States Department of Agriculture Wildlife Services: Staff Publications

The critically endangered Laysan teal Anas laysanensis (known as koloa po¯haka in the Hawaiian language), in the northwestern Hawaiian Islands has wild populations on Kamole (Laysan Island), Kuaihelani (Midway Atoll NWR) and Ho¯laniku¯ (Kure Atoll). The Laysan teal face a new risk on Sand Island in Kuaihelani: non-target poisoning via a pending House Mouse Mus musculus eradication program. After mice were observed attacking and depredating Laysan albatross Phoebastria immutabilis (mo¯lı¯) in 2015, plans to eradicate the mice were developed to protect this seabird species. This approach, however, risks poisoning the Laysan teal. To reduce exposure, teal will be translocated during …

Raccoon Densities Across Four Land Cover Types In The Southeastern United States, Jocab E. Hill, James L. Helton, David A. Bernasconi, Wesley C. Dixon, Matt T. Hamilton, Richard B. Chipman, Amy T. Gilbert, James C. Beasley, Guha Dharmarajan, Olin E. Rhodes Jr.

United States Department of Agriculture Wildlife Services: Staff Publications

Raccoons (Procyon lotor) are the primary reservoir for rabies virus in eastern North America. Management of rabies in raccoons is achieved primarily with the use of oral rabies vaccination (ORV) and effective ORV bait densities are determined in part by the densities of raccoons. Decisions regarding ORV bait densities, however, are limited by an incomplete understanding of raccoon densities across the spectrum of landscapes they occupy. We carried out a markrecapture study of raccoons on the Savannah River Site in South Carolina, USA, from 2017–2019, to develop sex‐ and landscape‐specific raccoon density estimates across 4 rural land cover …

Dissertations and Theses Collection (Open Access)

Charismatic leadership oratory is critical in aligning the organisational vision and goals for business sustainability. This research focuses on charismatic leadership, particularly on oratory leading to charismatic perception by the audience. This research seeks to provide future leaders with a better perspective of the multigenerational workforce in an effort to customise the rhetorical process for this diverse workforce to enhance charismatic perception, thereby promoting organisational communication.

The audience in prior studies has been treated as a homogeneous unit (Clark & Greatbatch, 2011; Groß et al., 2015), without distinguishing between different generational groups and their respective receptiveness to a leadership oratory. …

Terrible Freedom, Ambiguous Authenticity, And The Pragmatism Of The Endangered: Why Free Speech In Law School Gets Complicated, Leonard M. Niehoff

Articles

We idealize colleges and universities as places of unfettered inquiry, where freedom of expression flourishes. The Supreme Court has described the university classroom as “peculiarly the ‘marketplace of ideas.’” It declared: “The Nation’s future depends upon leaders trained through wide exposure to that robust exchange of ideas which discovers truth out of a multitude of tongues, [rather] than through any kind of authoritative selection.” The exchange of competing ideas takes place not only in classrooms, but also in public spaces, dormitories, student organizations, and in countless other campus contexts.

Nutritional Medicine: Education For Advanced Practice Providers, Natalie Organ

Limited tailored FCR interventions and age-appropriate support exist. This Doctor of Nursing (DNP) project, based upon best practice guidelines, aimed to evaluate how a Lifestyle Management Coaching Intervention (LMCI) could help young female BC survivors learn how to decrease and manage their FCR more effectively and experience improved health outcomes.

Method: Eligible participants were female BC survivors aged 18-59 with Stage I-III BC demonstrating elevated baseline FCR screening scores during the extended survival period recruited from the …

Local Observations Of Climate Change And Impacts On Livelihoods In Kamchatka, Russia, Victoria N. Sharakhmatova, Drew Gerkey

Faculty Publications

Indigenous communities throughout the Arctic are confronting unprecedented challenges arising from anthropogenic climate change. The inextricable connections between their livelihoods and social and environmental systems, combined with a rich foundation of individual and inter-generational collective experience and knowledge, make Indigenous communities particularly adept at observing changes in climate and understanding their impacts. In this chapter, we apply the protocol from the Local Indicators of Climate Change Impacts project to document observations and impacts of climate change in Khailino, an Indigenous community on the northern part of the Kamchatka Peninsula in Northeast Siberia, Russia. We use individual interviews to identify what …

The Ghosts Of Chevron Present And Future, Gary S. Lawson

Faculty Scholarship

In the October 2021 term, the Supreme Court decided six cases involving federal agency interpretations of statutes, at least five of which seemingly implicated the Chevron doctrine and several of which explicitly turned on applications of Chevron in the lower courts. But while the Chevron doctrine has dominated federal administrative law for nearly four decades, not a single majority opinion during the term even cited Chevron. Three of those cases formalized the so-called “major questions” doctrine, which functions essentially as an anti-Chevron doctrine by requiring clear congressional statements of authority to justify agency action on matters of great legal and …

Law And Culture, Tamar Frankel, Tomasz Braun

Faculty Scholarship

We often speak of law and culture in one breath. That may be so because both systems impose on each person and organization required rules of behavior. Yet, law and culture are quite different, though they relate to and affect each other. Therefore, it is desirable to examine their similarities and differences and their relationship. While the structures of law and culture are more similar than we might expect, their differences greatly affect the enforcement of the rules issued under each.

To be sure, both systems consist of rules and their enforcement. Most of our thoughts and knowledge, and many …

Increasing Transplant Medication Knowledge Through Implementation Of A Medication Education Intervention Algorithm, Colleen Chime Karkhang

Yale School of Nursing Digital Theses

Limited health literacy (LHL) has profound implications on measured transplant outcomes as it is associated with higher incidence of graft loss, organ rejection, decreased immunosuppression medication adherence, and increased hospital re-admissions. Identification of patients with limited health literacy allows for opportunities to provide targeted medication education that allows patients to become more active participants in their care while increasing their transplant medication education knowledge and self-efficacy. The aims of this DNP projects were to develop and implement a medication education intervention algorithm that incorporates health literacy scores and evidenced based educational interventions amongst kidney transplant recipients (initial transplants and re-admissions) …

Pmp: Privacy-Aware Matrix Profile Against Sensitive Pattern Inference, Li Zhang, Jiahao Ding, Yifeng Gao, Jessica Lin

Computer Science Faculty Publications

Recent rapid development of sensor technology has allowed massive fine-grained time series (TS) data to be collected and set the foundation for the development of data-driven services and applications. During the process, data sharing is often involved to allow the third-party modelers to perform specific time series data mining (TSDM) tasks based on the need of data owner. The high resolution of TS brings new challenges in protecting privacy. While meaningful information in high-resolution TS shifts from concrete point values to local shape-based segments, numerous research have found that long shape-based patterns could contain more sensitive information and may potentially …

Pollution by chemicals and waste impacts human and ecosystem health on regional, national, and global scales, resulting, together with climate change and biodiversity loss, in a triple planetary crisis. Consequently, in 2022, countries agreed to establish an intergovernmental science–policy panel (SPP) on chemicals, waste, and pollution prevention, complementary to the existing intergovernmental science–policy bodies on climate change and biodiversity. To ensure the SPP’s success, it is imperative to protect it from conflicts of interest (COI). Here, we (i) define and review the implications of COI, and its relevance for the management of chemicals, waste, and pollution; (ii) summarize established tactics …

Race-Ing Antitrust, I. Bennett Capers, Gregory Day

Faculty Scholarship

Antitrust law has a race problem. To spot an antitrust violation, courts inquire into whether an act has degraded consumer welfare. Since anticompetitive practices are often assumed to enhance consumer welfare, antitrust offenses are rarely found. Key to this framework is that antitrust treats all consumers monolithically; that consumers are differently situated, especially along lines of race, simply is ignored.

We argue that antitrust law must disaggregate the term “consumer” to include those who disproportionately suffer from anticompetitive practices via a community welfare standard. As a starting point, we demonstrate that anticompetitive conduct has specifically been used as a tool …

Wildlife Value Orientations And Recreation Conflict: A Focus On Hunters And Non-Hunters In Alberta, Canada, Yuvana Sequeira

Theses and Dissertations (Comprehensive)

Parks and other forms of protected areas are considered a vital tool in the effective conservation of biodiversity. These areas also provide important spaces for nature-based tourism and recreation (NBTR), where activities such as hiking, swimming, canoeing, and socializing with friends and family often occur. In some cases, hunting may also occur within a protected area, but there is little understanding of how such activities affect the experience and overall satisfaction of other recreationists (and vise-versa). While NBTR is a popular and growing industry, there is limited research in Canada about the values of tourists and recreationists and the …

The Influence Of Decorin, A Potential Pro-Inflammatory Stimulant, On The Mechanical Properties Of The Annulus Fibrosus, Sabrina Sinopoli

Theses and Dissertations (Comprehensive)

Previous literature has investigated the biomechanical properties of various animal models, but few have studied an isolated and intact rat tail annulus fibrosus. Decorin, a class 1 small leucine-rich protein (SLRP) has the potential to trigger an inflammatory environment as previous research has shown that it may stimulate inflammation via the toll-like receptor (TLR) pathway. An increased inflammatory environment can have biomechanical implications for the disc, and so the ability of decorin to stimulate an environment that alters the mechanical properties of the disc was investigated.

The purpose of this study was to investigate the potential of decorin, a proteoglycan …

Spatial And Temporal Characteristics Of Historical Surface Climate Over The Northwest Territories, Canada, Bhaleka D. Persaud

Theses and Dissertations (Comprehensive)

Climate change is putting many of the Northwest Territories (NWT) ecosystems, its people and animal populations at risk due to accelerated warming, permafrost thaw, and changing precipitation regimes. As the NWT continues to warm, at disproportionately higher rates when compared to the rest of Canada, threats to the stability of NWT’s ecosystems are expected to increase. Consequently, understanding how climate warming has changed historically and its implications on natural ecosystems requires point-to-region-specific, long-term climatic data to elucidate important drivers of observed changes relevant to decision makers at community, Indigenous, Territorial and Federal government levels. However, in situ climate data are …

The Vital Role Of Dehcho Dene Knowledges In Climate Change & Permafrost Thaw Adaptation In Jean Marie River First Nation Nwt, Mackenzie Bell

Theses and Dissertations (Comprehensive)

Across the globe climate change has become an issue of growing concern for both Indigenous and non – Indigenous peoples alike. In Northern Canada this narrative is no different. For Indigenous groups such as the Jean Marie River First Nation (JMRFN) anthropogenic climate change is not only a reality but is visible through their daily interactions with the environment around them. Additional insight pertaining to these climatic changes and their impacts can be found through analyzing the traditional knowledge systems of the JMRFN and how these before mentioned interactions have changed over time. This two-year participatory research project has investigated …

Assessing The Biocatalytic Promiscuity Of Pep- Transformations For Geminal-Difluorination, Eloy Jose Torres Garcia

Theses and Dissertations (Comprehensive)

Fluorine is the most electronegative chemical element and can drastically change molecular properties, such as drug pharmacokinetics and agrochemical half-life. Although a great deal of progress is occurring in synthetic methods to access various organofluorines, these methods struggle with harsh conditions and limited substrate scope. Biocatalytic approaches offer the potential to access organofluorines that are difficult or impossible with the current methodology. Phosphoenolpyruvate (PEP) is a central metabolite and biosynthetic precursor for diverse molecules. Phosphoenol pyruvate mutase (Ppm) catalyses the interconversion of Phosphonopyruvate (PnPy) to Phosphoenolpyruvate (PEP). This research successfully expressed and …

Differences In Drifting Invertebrate Communities Across Arctic Ecozones And The Influence On Potential Growth Of Grayling (Thymallus Arcticus), Charles Chanyi

Theses and Dissertations (Comprehensive)

Invertebrate drift is a key process that potentially affects multiple levels of food web organization within stream environments. However, our understanding of the mechanistic drivers of drift in high latitude streams and subsequent bottom-up control that drift may have on fish predators in these environments remains understudied. This project aimed to gain the baseline knowledge of how drift functions across two major high latitude ecozones, the boreal forest and tundra, and how those possible differences in drifting community characteristics may impact drift-feeding Arctic grayling (Thymallus arcticus). These objectives were accomplished by characterizing stream environments across both ecozones, sampling …

Intermittent Sucrose Access: Sweetness Versus Calories, Jarret Folmer, Rudy Eikelboom

Theses and Dissertations (Comprehensive)

Nondeprived rats receiving every 3^rd day access (E3DA) to 4% sucrose solution consume more sucrose on access days compared to rats with everyday access (EDA). Rats receiving EDA or E3DA to 16% sucrose do not consume different amounts, but if placed on every 2^nd day access (E2DA) to 4% sucrose E3DA-group rats consume more than EDA rats (Eikelboom, Hewitt, & Adams, 2022). E3DA affects rats’ value of sucrose but effects appear hidden with high sucrose concentrations. Valyear and Eikelboom (2021) suggested that calorie ceilings limit E3DA-induced consumption with high sucrose, but this ceiling could also be caused by …

Exploring The Effectiveness Of Ecological Momentary Assessment And Video At Eliciting The Impact Of Park Features On Human Health And Well-Being In A Protected Area Context, Katelyn O'Bright

Theses and Dissertations (Comprehensive)

It is increasingly recognized that contact with nature in parks and other forms of protected areas provides benefits to visitors’ physical, mental, social, spiritual, and intellectual health and well-being. However, the methods used to assess these outcomes, including the influence of different environmental features that lead to these benefits, is under-researched. To address this gap, this study used a mixed methods design to explore the effectiveness of using Ecological Momentary Assessment (EMA) and video to assess the impact of various park features on the self-perceived (subjective) health and well-being of visitors. Participants were prompted by a mobile application on their …

Characterizing The Rhizosphere Microbial Community Of Food Crops In A Changing Climate, Samuel Snider

Theses and Dissertations (Comprehensive)

In recent years, there have been increased occurrences of food-borne illness in Canada, which is not directly associated with animal-related products but is caused by the increasing prevalence of pathogenic outbreaks in fresh produce. This can have health and economic impacts on the agriculture industry in Canada. As such, it is essential to better understand the plant-microbe interactions of crops grown in Canada and determine how climate change may alter the relationship. Plants can promote the growth of beneficial bacteria in the rhizosphere, which can create protective competition between beneficial and pathogenic bacteria. Changes in the environment of the rhizosphere …

“It Felt Like A Sense Of Rape:” Women’S Experiences Of Strip Searching In Prison As Gendered, Misogynoir, And Colonial Genocidal Sexual Violence, Jessica Hutchison

Theses and Dissertations (Comprehensive)

Previously imprisoned women have long been sounding the alarm about the harms of strip searching and calling for it to be banned. However, it remains a routine prison practice and research into it is scant. Furthermore, Canada is incarcerating Indigenous women at genocidal levels and disproportionately imprisoning Black women. Therefore, my research explored the use of strip searching in federal prisons through anti-colonial and anti-racist feminist frameworks, specifically, abolition feminism.

My research was grounded in the ethic of relational accountability and centred reciprocity, respect, and responsibility in each phase. I gathered stories from 23 formerly incarcerated women from across Canada …

An Exploration Of The Link Between Vertebral Endplate Fracture, Velocity, And Health Of The Intervertebral Disc., John Mcmorran

Theses and Dissertations (Comprehensive)

The capacity for fractures to manifest in the growth cartilage of the adolescent human spine is well documented, but much of the knowledge available regarding such fractures remains retrospective and is largely composed of small case series made up of relatively few participants. In-vitro tissue testing has demonstrated that pressurization of the intervertebral disc’s nucleus pulposus significantly contributes to the generation of growth plate fractures. However, a comprehensive biomechanical investigation of the mechanical consequences for the intervertebral disc when exposed to ring apophyseal (growth plate) fractures at different velocities remains to be demonstrated.

The first two experiments of the present …

Action Strategies Of Young Adults During An Attentionally Demanding Collision Avoidance Task In Virtual Reality, Brooke J. Thompson

Theses and Dissertations (Comprehensive)

Walking and navigating through cluttered environments is a task that people do almost automatically while completing multiple cognitive and motor tasks simultaneously. Vision plays an essential role in adaptive locomotion as it allows individuals to make anticipatory actions (i.e., alter trajectory and/or gait speed) to successfully avoid oncoming collisions (Cinelli et al., 2008; Patla, 1997). To initiate a behaviour change at the appropriate time, humans rely on optical variables such as time-to-contact (TTC) (Cinelli & Patla, 2007). After determining when to initiate an avoidance behaviour, it is thought that humans maintain a protective zone (i.e., safety margin) by controlling the …

Nitrogen: Both A Potential Stimulator And Suppressor Of Cyanobacterial Blooms In Temperate Lakes, Catherine Goltz

Theses and Dissertations (Comprehensive)

Cyanobacterial blooms are complex phenomenon that are impacted and controlled by various factors such as lake depth, air temperature, wind, and nutrient loading. Nutrients such as phosphorus, nitrogen and iron all have very differing effects on cyanobacterial blooms. While phosphorus and iron are known to drive cyanobacterial biomass, nitrogen has been observed to have a direct impact on toxin synthesis. Nitrogen exists in the environment in many different forms such as atmospheric N₂, in inorganic forms such as nitrate and ammonium as well as in organic forms such as urea which can all affect cyanobacterial bloom development differently. …

A Close Look At The Connections Between Mental-State Talk, Theory Of Mind, And Source Monitoring During Parent-Child Reminiscing Of Emotional Events, Mallory Earnshaw

Theses and Dissertations (Comprehensive)

Autobiographical memories play a critical role in shaping personal identity, regulating emotions, and guiding future behaviour. Reminiscing about these memories can be particularly beneficial for coping with negative experiences. This study investigated the connections between mental-state talk, theory of mind, and source monitoring in parent-child reminiscing, and how it can be influenced by remembering enjoyable versus frustrating events. This study involved children ages 3-8 (N = 50) and consisted of two sessions. In the first session, the child reminisced with their parent about an enjoyable and frustrating event and completed two source-monitoring tasks. In the second session, the child …

Phosphorus Release And Recovery From Simulated Ferric Wastewater Sludge, Aseel Alnimer

Theses and Dissertations (Comprehensive)

Phosphorus (P) is a fundamental element necessary for all life forms and a key component in the fertilizer industry. Meanwhile, the excessive load of P to water bodies due to human activities has the potential to promote eutrophication. Wastewater treatment plants remove P either biologically or chemically and produce P rich sludge which could be a potential renewable source for P. At present, commercial technologies exist for P recovery from biological wastewater sludge. However, P recovery from chemical sludge particularly iron(III)-phosphate (Fe-P) sludge generated in chemical P removal plants that use iron(III) salts remains a challenge.

This study explored, in …
