Black Vulture Conflict And Management In The United States: Damage Trends, Management Overview, And Research Needs, Bryan M. Kluever, Morgan Pfeiffer, Scott C. Barras, Brett Dunlap, Lee A. Humberg

United States Department of Agriculture Wildlife Services: Staff Publications

Contrary to rapid declines of many vulture (Accipitridae, Cathartidea) species worldwide, black vulture (Coragyps atratus) populations are increasing and expanding their range in North America. Vultures exhibit complex behaviors and can adapt to any human-dominated landscape or land use. These traits, combined with population growth and range expansion, have contributed to increased human–vulture conflicts. Our goal was to summarize the current status and trends in human–black vulture conflicts (hereafter human– vulture conflicts), review available management strategies, identify knowledge gaps, and provide recommendations to enhance management and understanding of this species and the associated conflicts. We found human–vulture conflicts …

Review Of Ospreys: The Revival Of A Global Raptor, By Alan F. Poole. 2019., Lisa Fields, Brian E. Washburn

United States Department of Agriculture Wildlife Services: Staff Publications

For the past three decades, Alan Poole’s (1989) Ospreys: A Natural and Unnatural History has provided a solid foundation for those seeking a primer on the basic biology and ecology of Ospreys (Pandion haliaetus). Poole’s summary of knowledge about Ospreys was written at a time when these amazing birds were recovering from their DDTinduced population crash, but this important book has long been out of print. In the intervening decades, much has been learned regarding Ospreys. In his new book, Ospreys: The Revival of a Global Raptor, Poole guides the reader through a tour of Ospreys’ worldwide distribution and population …

Population Increases Of Large Birds In North America Pose Challenges For Aviation Safety, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

There is a strong correlation between bird mass and the likelihood of aircraft damage during a bird–aircraft collision. Thus, the U.S. Federal Aviation Administration (FAA) has established airworthiness standards related to bird mass for engines, airframes, and windshields. Most standards use large (1.8 kg) and medium (1.1 kg) birds as benchmarks (the empennage and certain large turbofan engines use a 3.6-kg bird). There are 20 large (≥1.8 kg) and 16 medium (1.1–1.7 kg) bird species in North America with ≥20 strikes reported for civil aircraft (FAA National Wildlife Strike Database), 1990 to 2018. I analyzed the population changes of these …

One Step Closer To A Better Starling Trap, James R. Thiele

United States Department of Agriculture Wildlife Services: Staff Publications

European starlings (Sturnus vulgaris) are an invasive species in the United States that damage agriculture, personal property, and threaten human health and safety. The U.S. Department of Agriculture Wildlife Services provides technical support to mitigate damage by controlling starling populations at concentrated animal feeding operations, landfills, utilities, and urban areas. Wildlife Services uses DRC-1339, a registered toxicant, to reduce starling populations. Trapping can also be an effective tool but requires more time at a higher cost than DRC-1339. Trapping starlings, however, may be needed to provide a viable alternative to mitigate damage in areas where toxicant use may …

Relationships Between Education Track, Adverse Childhood Experience, And Recidivism Among Juveniles, Catherine Gammage

Electronic Theses and Dissertations

A high recidivism level, despite attempts by regulatory agencies and various institutions to decrease it, is currently a disturbing problem of the juvenile justice system. Adjudicated youth released from residential treatment centers are often reincarcerated within 3 years after their release. Residential treatment centers provide mandated educational and treatment services for all incarcerated youth. The educational programs offered by residential treatment centers should include academic and career technology programs which support community reintegration. The opportunity for students to receive a high school diploma and industry certifications for career readiness is an important way to decrease recidivism for juveniles. This study …

Effects Of Phosphorus On Mycorrhizal Colonization Of Wetland Plants Under Natural And Controlled Conditions, Miriah Tucker

Theses and Dissertations (Comprehensive)

An important symbiotic relationship that forms in wetland environments occurs between plants and arbuscular mycorrhizal fungi (AMF). In terrestrial communities AMF colonization is limited by phosphorus; excessive phosphorus can lead to an uncoupling of the relationship. Few studies have examined the relationship between AMF and phosphorus concentration in wetland plants. The studies that have, found a decrease in AMF colonization at phosphorus concentrations as low as 0.03 mg/L P, however, methodological issues limit the interpretation of these results. To address this, a field and greenhouse study were completed using more realistic exposure conditions, field deployable assays (FDA), and natural intact …

An Evaluation Of The Timeline As A Memory Retrieval Aid For Children’S Recall Of Specific Details From A Repeated Event, Huan Huan Zhang

Theses and Dissertations (Comprehensive)

Investigators and prosecutors are heavily dependent on children’s testimony in abuse cases where physical evidence is often lacking, making children the sole source of information. Decades of research have shown that young children are indeed capable of accurately recalling events from the past. Findings from research on interview techniques suggest that interview aids such as dolls and human diagrams are often not helpful and pose risks of eliciting inaccurate reports unless they are used cautiously and non-suggestively at the end of the interview.

The timeline, which is a visual depiction of time, is another type of interview aid that is …

Fanm Pa Chita: Mobilities, Intimate Labour, And Political Subjectivities Among Haitian Women On The Move, Masaya Llavaneras Blanco

Theses and Dissertations (Comprehensive)

This dissertation asks: how does intimate labour interact with the mobility and political subjectivities of Haitian migrant women and women of Haitian descent in the Dominican Republic (DR)? It answers this question in three specific ways. First, it explains the relationship between intimate labour and the spatial trajectories of women of Haitian ancestry who work as domestic workers. Second, it examines how the interaction between intimate labour and human mobility plays out in the Dominican border regime. Third, it explains how these subaltern women act politically in the midst of the intersections between borders, mobilities, and intimacy.

The dissertation proposes …

Lgtbq+ Community Perceptions Of Police And Police Involvement In Pride Celebrations In A Small Ontario City: An Exploratory Study, Priscilla Ramjit

Theses and Dissertations (Comprehensive)

As literature and media findings suggest, the relationship between the LGTBQ+ community and the police is complex. This qualitative research study seeks to better understand the relationship between the Ruralcity LGTBQ+ community and the Ruralcity Police Service in a small city in southwestern Ontario—“Ruralcity”. Through the epistemological lens of symbolic interactionism and the critical approach of queer theory, I gathered the perspectives of five Ruralcity LGTBQ+ participants on the local police, including the kinds of interactions the participants have had with the police and how the police presence and absence at Ruralcity PRIDE events impact the participants’ sense of well-being. …

A Housing First Model For Youth And Its Relation To Social Integration, Alexandra Amiri

Theses and Dissertations (Comprehensive)

The present study explored how a Housing First for Youth intervention, working from an empowerment theory approach, influences the social integration of youth experiencing homelessness. This was done by contrasting between groups of individuals who either did or did not receive the intervention. The sample consisted of 86 youth in the city of Ottawa between the ages of 17-24 who were randomized into the intervention (n=44) or treatment as usual group (n=42). Quantitative data from baseline and 6-month follow-up were analyzed using the Community Integration Scale (CIS) and Multidimensional Scale of Perceived Social Support (MSPSS). Repeated measures ANOVA revealed an …

Holy Estrangement: The Poetics Of Estrangement In John Donne's Divine Poems And Sermons, Anton Bergstrom

Theses and Dissertations (Comprehensive)

This dissertation examines literary estrangement, that is the act and effect of making the familiar strange in a literary work, in the religious poems and sermons of the poet-preacher John Donne (1572–1631). My study uncovers and explores what Donne "estranges," how he achieves this, and for what purpose, as well as the practices and modes of thinking that shaped his poetics. In Donne's religious verse and prose, making the familiar and traditional tropes, images, doctrines, and events of Christianity strange forms active readers and revitalizes those elements, imbuing them with newfound interest, significance, and affective power.

My study offers a …

“There’S No Manual For This”
: A Multi-Case Study Exploring Familial Experiences Of Maternal Incarceration, Lauren Hawthorne

Theses and Dissertations (Comprehensive)

Women are the fastest growing prison population in the world (ICPR, 2017). This holds true in the Canadian context, where 70% of federally incarcerated women are mothers to children under 18 (Sapers, 2015). Inevitably, the carceral experience is inherently familial: the experiences of criminalized women cannot be extricated from that of their families, and the experiences of children and caregivers cannot be extricated from that of the criminalized mother and other family members. Yet, there is a great deal that we do not know about incarceration and family life—particularly from the perspectives of caregivers, mothers, and children themselves. This multi-case …

Determination Of Samarium And Dysprosium Solubility, Seana Brennan

Theses and Dissertations (Comprehensive)

In recent years, the use of Rare Earth Elements (REE) has rapidly increased, resulting in numerous potential anthropogenic inputs to the environment. As a result, these metals are emerging as microcontaminants and pose a potential threat to aquatic life. However, the toxicity of REE are largely unknown due, in part, to the limited information on their chemical speciation. The purpose of this project was to gain an understanding of REE precipitate formation and solubility as the foundation for the development of the chemical equilibrium component of toxicity prediction models. Solubility experiments were conducted with Samarium, (Sm), a light REE, and …

A Qualitative Investigation Into The Influence Of A Mental Health Physical Activity Intervention On University Students, Heather M. Tunks

Theses and Dissertations (Comprehensive)

Objective

Among the university student population, mental illnesses are highly prevalent. Adults aged 20-30 years have the highest rates of mood and anxiety disorders than any other age group, with approximately 12.0% diagnosed with an anxiety disorder and 7.0 to 9.0% experiencing clinical depression (Nunes et al., 2014; Pedrelli, Nyer, Yeung, Zulauf, & Wilens, 2015). Reducing or preventing the effects of mental illness among this population may have lifelong implications including improvements in coping and management of mental illness throughout the lifespan(Jaworska, DeSomma, Fonseka, Heck, & MacQueen, 2016). This research examines the lived experiences of volunteers and participants in a …

Theses and Dissertations (Comprehensive)

This qualitative research explored the lived experience of respect for second-generation Korean Canadian pastors within the Korean Church context. In order to gain a deep understanding of the lived experience of respect, the hermeneutic phenomenological approach was used to collect the data and document the findings. All the twelve participants participated in an in-depth semi-structured interview which lasted 50-75 minutes. The transcribed participant interviews were analyzed for themes and sub-themes.

The following three themes emerged: why is respect expected within the Korean Church, when is respect expressed within the Korean Church, and how is respect experienced within the Korean Church. …

Structural And Functional Characterization Of Cazyme And Cazyme-Related Proteins From: Bacteroides Thetaiotaomicron And Porphyromonas Gingivalis: Two Abundant Colonizers Of The Human Microbiome, James Stevenson

Theses and Dissertations (Comprehensive)

The human body consists of approximately 30 trillion cells, while non-human microbes that reside on and within the body outnumber human somatic cells by a factor of 1.3 – 2.3. The interplay between our cells and those of the colonizing microorganisms affect physiology in a multitude of ways, both beneficial and detrimental. Microbes found in the oral cavity, such as the Red Complex member Porphyromonas gingivalis, are associated with pathology, namely periodontal diseases including gum deterioration, tooth decay, and loss of underlying alveolar bone. At the other end of the gastrointestinal tract, microbes such as Bacteroides thetaiotaomicron are found …

Characterizing The Hydrological Function Of Treed Bogs In The Zone Of Discontinuous Permafrost, Brenden Disher

Theses and Dissertations (Comprehensive)

The loss of permafrost has produced a wholesale conversion from forest to wetland, and many studies have analyzed the effects of permafrost thaw-induced land cover change on the hydrology and ecology of landscapes within the Taiga Plains. The permafrost thaw driven areal shrinkage of forested plateaux and their replacement by treeless wetlands is well documented, and the co-occurrence of permafrost and black spruce forest cover is the basis for areal estimates of the former. However, field studies conducted at a peatland dominated landscape near Fort Simpson, NWT indicate that tree canopy may persist following the loss of permafrost and the …

What Makes An Image Memorable? Effects Of Encoding On The Mechanism Of Recognition, Asiya Gul

Theses and Dissertations (Comprehensive)

Memory is undoubtedly one of the most important processes of human cognition. A long line of research suggests that recognition relies on the assessment of two explicit memory phenomena: familiarity and recollection. Researchers who support the Dual Process Signal Detection (DPSD) model of recognition memory link the FN400 component (a negative ERP deflection peaking around 400 ms at frontal electrodes) with familiarity; however, it is currently unclear whether the FN400 reflects familiarity or implicit memory. Three event-related potentials (ERP) studies were conducted to determine whether implicit memory plays a role in setting up encoding strategies, and how these encoding strategies …

Impacts Of Transportation Infrastructure On Water Quality, Sediment Loads, And Fishing Opportunities In The Gwich’In Settlement Area, Northwest Territories, Matthew Teillet

Theses and Dissertations (Comprehensive)

The addition of gravel sediment to build ferry landings on the Peel and Mackenzie Rivers has been an ongoing concern for the Gwich’in communities of Fort McPherson and Tsiigehtchic that depend on the rivers for their livelihoods. Specifically, there are concerns that gravel from ferry landings is degrading water quality, harming fishing opportunities, and altering river morphology downstream. Previous reports concluded that ferry operations were not impacting downstream ecology. However, past studies had methodological shortcomings and community concerns about the ferry landings remain. To study the impact of the gravel landings on water quality, I utilized a multidisciplinary study design …

Theses and Dissertations (Comprehensive)

This research project explores the experiences of school social workers partnering with trained, accredited facility dogs in an Ontario school board. A qualitative research methodology using an interpretative phenomenological analysis has been employed. Results reveal that organizational support is key to the successful integration of facility dogs in clinical social work practice within a school board. Environmental considerations allow for the establishment of therapeutic conditions that support positive interactions and interventions with a canine. Findings clarify three dimensions of canine-assisted therapy: connection, attunement and the handler-canine relationship. Connection is the ‘magic’ of canine-assisted therapy, the essence of an interaction between …

“This Is My Little World…”: Navigating The Group Exercise Experience Of Stay-Fit Members, Olivia Jones

Theses and Dissertations (Comprehensive)

Objective

Cancer is the leading cause of death in Canada, with one in two Canadians expected to develop cancer over their lifetime (Canadian Cancer Society, 2019). Exercise is reportedly a safe therapy to help ease the common side effects of cancer and its treatments (Schmitz et al., 2010). Past research has shown the benefits of group exercise while in treatment for cancer, but there is a dearth of research regarding the impact of long-term group exercise programming for cancer survivors. This phenomenological study explored the lived experiences of group exercise participation for individuals who previously had cancer and were enrolled …

A Threat Assessment Of Radicalized Extremist Right-Wing White Nationalist Subcultures In Canada: A Social Media Analysis, Dylon Groom

Theses and Dissertations (Comprehensive)

As literature and media findings suggest, right-wing extremism has been a growing threat to the security of Canada. This qualitative research study seeks to develop a better understanding of the way Canadian right-wing white nationalists develop online in order to aid future radicalization research. After the tragic attacks on September 11^th, 2001, radicalization research has largely been focused on Islamist extremism. By utilizing a conventional content analysis approach to the open-sourced white nationalist discussion forum, stormfront.org, this thesis bridges the gap between the understanding of Islamist extremism and right-wing white nationalists. Ten Canadian white nationalists active on the …

Theses and Dissertations (Comprehensive)

Childhood and adolescence can be difficult for young people as they navigate a variety of significant transitions. Thus, it is imperative that researchers focus on programs that support children and adolescents during this time. Mindfulness and self-compassion are two such programs that may promote positive youth development. Mindfulness and self-compassion have been explored in the adolescent context, and mindfulness has been explored with young children, however research on self-compassion for children is currently lacking. The present studies were designed to examine the feasibility, acceptability and potential benefits of a combined mindfulness + self-compassion program for children and adolescents in the …

Constructions Of Sympathy: A Media Discourse Analysis Of Detained Children And Youth In Canada, Lauren Ashby

Theses and Dissertations (Comprehensive)

Over the last few years, there has been an abundance of media articles published on irregular migrants (Msefer, 2017). While there is much research attention on media discourse on individual adult asylum seekers and refugee claimants, there is little research attention on how media portrays detained children and youth affected by immigration detention. A deductive content analysis of 35 Canadian newspaper articles published between January 1, 2013 and December 31, 2019 was conducted to explore the media discourse of youth held in immigration detention. Social construction of social problems (SCSP, Best, 2017) theory focuses on the way people create an …

Through The Lurking Glass: A Qualitative Media Analysis Of Traditional Gender Norms And Stalking Depictions In Film, Alexandra Baril

Theses and Dissertations (Comprehensive)

This thesis examines to what extent traditional gender norms are adhered to by the depiction of stalkers within films. Stalking has only recently been recognized as a social problem. Due to the relatively new attention, there has been a lack of research surrounding the way in which stalkers and stalking behaviours are being portrayed within popular media, particularly film media. This paper uses a qualitative ethnographic content analysis approach to examine these stalking depictions. Twenty films that had a high level of stalking portrayed behaviours, and thriller genres rather than horror genres, were collected and analyzed. It was found that …

Narrating A Conscientization Journey On Crime Prevention Through Social Development, Carlos Luis Zatarain

Theses and Dissertations (Comprehensive)

There is an increasing interest among municipalities to address crime through prevention as social development (CPSD) that acknowledges the underlying social conditions that influence the occurrence of crime. This requires a critical consciousness among community members and decision-makers of the root causes of crime and critical action that reflect that understanding. This, in turn, implies both a significant mental and cultural shift requiring personal transformation. Only then can the appropriate actions towards a preventative approach to crime be effectively fostered. For this purpose, the Waterloo Region Crime Prevention Council developed a community course titled Reframing Crime, Justice, and Prevention that …

Cultural Diversity In Interdependent Sport Teams, Michael J. Godfrey

Theses and Dissertations (Comprehensive)

Group member characteristics are key factors that underpin a team’s structure (e.g., roles), emergent states (e.g., cohesion), processes (e.g., goals), and subsequently both individual (e.g., retention) and group (e.g., performance) outcomes (Carron & Eys 2012). Furthermore, the importance of considering individuals’ cultural backgrounds (as specific member characteristics) contributing to individual and group outcomes has recently been expressed within sport psychology (Schinke et al., 2014). Although sporadic attempts have examined cultural diversity in professional sport contexts in relation to performance and revenue (e.g., Maderer et al., 2014), the majority of empirical research examining the effects of cultural diversity on small groups …

Plasmonic Slab Waveguides: Theory & Application For Sensors, Anum Khattak

Theses and Dissertations (Comprehensive)

Through surface plasmon polaritons (SPPs) that propagate along the interface between a metal and a dielectric material, plasmonic waveguides have the ability to confine light at subwavelength scale beyond the diffraction limit, which opens a promising platform to further downsize the active and passive photonic devices. The fields of the SPPs have maximum amplitude at the metal/dielectric interface and decay exponentially toward both media, where the penetration of the fields in the dielectric is very susceptible to the change in the refractive index of the dielectric. This makes surface plasmon resonance (SPR) a remarkable technique in sensor applications to investigate …

Tough But Not Enough: Female University Athletes Self-Reported Mental Toughness, Kerrie Trottier

Theses and Dissertations (Comprehensive)

Background: Mental health and sport related mental toughness have become prominent in the media in recent years. Successful athletes cope with stressful situations by building their mental toughness in response to challenging conditions. In university, athletes are required to maintain performance standards, school standards of excellence, and continue to develop their mental toughness. This study was motivated by the limited knowledge associated with female athletes, at a unique point in their life where they are challenged both academically, socially, and in their chosen sport.

Methods: This study proposed the following two questions; “What are the factors associated with mental toughness …
