Exploring Psychological Readiness To Return To Sport After Injury, Scott Donald

Theses and Dissertations (Comprehensive)

Athletes are often cleared to return to sport with little emphasis on psychological readiness in relation to physical readiness. This is important because athletes who are not psychologically ready to return to sport (RTS), despite being physically cleared, may lack motivation to compete and lack confidence in their abilities (Podlog, Banham, Wadey, & Hannon, 2015), drop out of sport, fear re-injury (Ardern et al., 2014), worry about future performance (Podlog & Eklund, 2006), experience anxiety and feel depressed (Tracey, 2003) or incur further injury (McCullough et al., 2012). Remarkably, there is no definition of psychological readiness consistently used in the …

From Inclusive Governance To Peace: Exploring African Governance Systems, Karolina Werner

Theses and Dissertations (Comprehensive)

This dissertation defines and explores the concept of inclusive governance, highlighting linkages between inclusion in governance, legitimacy, and peace. Focusing specifically on the inclusion of traditional, local systems of governance in state government, I explore the unique role traditional institutions have as a bridge between the communities they serve and the government. I examine the relationship between governance, quality of inclusion, legitimacy, and sustainable peace through case studies, challenging prevailing narratives and conceptualizing inclusive governance through a reflexive analysis of existing literature, theory, and empirical evidence.

I offer a case study analysis of Uganda highlighting the relationship between state government …

Free, Prior, And Informed Decision-Making About Proposed Development On Indigenous Territories In Northern Ontario, Courtney Arseneau

Theses and Dissertations (Comprehensive)

This case study examined the experiences of consultation and consent-seeking processes among nine Indigenous communities in northern Ontario that, individually and collectively, are faced with complex decisions to be made since the discovery of several significant mineral deposits on their traditional territories. In examining the processes involved in making informed development decisions, this dissertation addressed four key research questions: 1) What are the roles, processes, laws and rights frameworks that influence resource governance in the Matawa First Nations region? 2) How is free, prior, and informed decision-making described by people living and working in the Matawa First Nations region? 3) …

Using Social Media To Engage Toronto Communities For Resiliency And Stress Planning, Martha Ta

Theses and Dissertations (Comprehensive)

As Toronto’s low-income areas grow, the city’s neighbourhoods experience a segregation by low- and high-income, contributing to chronic stress as environmental determinants and leading to negative health outcomes and chronic diseases. This study identified Crescent Town as one of the Toronto neighbourhoods with potentially high levels of chronic emotional stress through an analysis of emotions indicated by Tweets, as well as triangulation with administrative data describing relevant neighbourhood indicators. Crescent Town community members (n=23) were engaged using concept mapping to identify existing neighbourhood stressors and assets and empowered to strategize solutions. The ten-cluster solution created with six clusters describing neighbourhood …

The Use Of Public Consultation To Construct Sex Work Related Policies, Ryan Horan

Theses and Dissertations (Comprehensive)

The present study is a qualitative analysis of the Online Public Consultation of Prostitution -Related Offences (OPCPRO), conducted by the Canadian Department of Justice in 2014. This research describes themes that arose within the discourses of respondents to the OPCPRO, and offers a critical examination of the use of online consultations in the production of public policy. I argue that respondents to the OPCPRO, regardless of their support or opposition for criminalization of sex work, strategically draw on values echoed within the Charter of Rights and Freedoms to frame their policy propositions as consistent with sex workers individual rights. I …

Examining The Potential Involvement Of Sex Hormones On Appetite Regulation In Females Across The Menstrual Cycle, Sara Cabral Moniz

Theses and Dissertations (Comprehensive)

Appetite regulation has exclusively been examined during the follicular phase (FP) of the menstrual cycle, and it remains unclear whether the greater levels of estradiol (E₂) and progesterone (P₄) in the luteal phase (LP) affect this process. Thus, the purpose of this study was to utilize vigorous-intensity continuous training (VICT) as a method to modulate plasma concentrations of E₂ and P₄ and examine their associations with post-exercise alterations in acylated ghrelin, peptide tyrosine-tyrosine_3-36 (PYY_3-36), active glucagon like peptide-1 (GLP-1), subjective appetite perceptions, and energy intake across the menstrual cycle. Eleven women …

Investigating The Antiviral Effects Of Vig-3 From Rainbow Trout, Shanee Herrington-Krause

Theses and Dissertations (Comprehensive)

Rainbow trout is the most farmed fish in Ontario, and thus is economically important to the province. Despite this, there is a lack of understanding regarding fish innate immunity, specifically with regards to interferon-stimulated genes (ISGs) and their antiviral effector functions. ISGs are the workhorses of the innate antiviral response, operating together to limit each step of virus replication. The Viral Hemorrhagic Septicemia Virus (VHSV) induced gene (Vig)-3 is a newly identified ISG within many fish species and is homologous to ISG-15 in mammals. It is a small ubiquitin-like protein inducible by type I interferon (IFN-I), and is suggested to …

Expression, Purification, Functional Characterization And Crystallization Of Three Porphyromonas Gingivalis Gene Products, Katarina Mandic

Theses and Dissertations (Comprehensive)

Dental biofilms are coupled polymicrobial aggregates that have attached to solid surfaces in the oral cavity. These collections of microorganisms are known to cause periodontal diseases that commence as localized inflammation of the gingiva and if untreated, eventually lead to irreversible alveolar bone resorption and tooth loss. Porphyromonas gingivalis is one of three periodontal pathogens that make up the “Red Complex”; a bacterial consortium responsible for the production of polysaccharide-rich biofilms that are essential to the inception and progression of periodontal disease. The dysbiosis and destructive inflammation caused by these organisms propel a self-sustained feed-forward loop that perpetuates periodontal disease. …

Older Adults’ Social Networks And The Role Of A Telephone Helpline Program, Harmanpreet (Preet) Chauhan

Theses and Dissertations (Comprehensive)

Over the past century, advances in health care, higher levels of education, and improved living conditions have resulted in increased human life expectancy. However, with longer life expectancy comes potential challenges to quality of life, as individuals may face numerous transitions in older age: children leaving home, employment to retirement, or physical declines possibly leading to lack of mobility. As a result, older adults may experience social isolation and difficulty in building new relationships. This is problematic, as lack of social connection is a strong predictor of lower physical and mental health (Fiori & Jager, 2012; Fiori, Smith, & Antonucci, …

Exploring The Personhood And Citizenship Of Persons With Disabilities Among Konkombas In Rural Ghana, Festus Moasun

Theses and Dissertations (Comprehensive)

Persons with disabilities (PWDs) are susceptible to various forms of mistreatments, particularly in the developing world, such that their personhoods are called to question. It was for this purpose that I set out to explore the personhood and citizenship of PWDs in rural Ghana. I used the constructivist paradigm in addition to the personhood and critical disability theories to guide the study which was conducted using an interpretive phenomenological research approach. To make the findings of the study participant driven, semi-structured interviews were held with PWDs. The findings revealed personhood to be perceived in a rank order of three semi-fluid …

Exploring K-12 Superintendent Turnover: Career Advancement Or Dissatisfaction Realized?, Francis Arthur Schill

Theses and Dissertations

Leading educational reform is one of a superintendent’s many roles, which involves working with elected school board members with varying beliefs of what constitutes educational reform. Superintendents accept this responsibility despite the considerable challenge that meaningful educational reform efforts take at least five years (Fullan & Stiegelbauer, 1991). The average stay of a superintendent in a school district is six and a half years, further complicating reform efforts (Glass & Franceschini, 2007). The purpose of the study was to better understand the factors that lead to the turnover of superintendents of K-12 schools in North Dakota.

Reproducible K-Means Clustering In Galaxy Feature Data From The Gama Survey, Sebastian Turner, Lee S. Kelvin, Ivan K. Baldry, Paulo J. Lisboa, Steven N. Longmore, Chris A. Collins, Benne W. Holwerda, Andrew M. Hopkins, Jochen Liske

Faculty and Staff Scholarship

A fundamental bimodality of galaxies in the local Universe is apparent in many of the features used to describe them. Multiple sub-populations exist within this framework, each representing galaxies following distinct evolutionary pathways. Accurately identifying and characterizing these sub-populations requires that a large number of galaxy features be analysed simultaneously. Future galaxy surveys such as LSST and Euclid will yield data volumes for which traditional approaches to galaxy classification will become unfeasible. To address this, we apply a robust k-means unsupervized clustering method to feature data derived from a sample of 7338 local-Universe galaxies selected from the Galaxy And Mass …

The Frequency Of Dust Lanes In Edge-On Spiral Galaxies Identified By Galaxy Zoo In Kids Imaging Of Gama Targets, Benne W. Holwerda, Lee Kelvin, Ivan Baldry, Chris Lintott, Mehmet Alpaslan, Kevin A. Pimbblet, Jochen Liske, Thomas Kitching, Steven Bamford, Jelte De Jong, Maciej Bilicki, Andrew Hopkins, Joanna Bridge, R. Steele, A. Jacques, S. Goswami, S. Kusmic, W. Roemer, S. Kruk, C. C. Popescu, K. Kuijken, L. Wang, A. Wright

Faculty and Staff Scholarship

Dust lanes bisect the plane of a typical edge-on spiral galaxy as a dark optical absorption feature. Their appearance is linked to the gravitational stability of spiral disks; the fraction of edge-on galaxies that displays a dust lane is a direct indicator of the typical vertical balance between gravity and turbulence: a balance struck between the energy input from star formation and the gravitational pull into the plane of the disk. Based on morphological classifications by the Galaxy Zoo project on the Kilo Degree Survey (KiDS) imaging data in the Galaxy and Mass Assembly (GAMA) fields, we explore the relation …

We have observed the G23 field of the Galaxy AnMass Assembly (GAMA) survey using the Australian Square Kilometre Array Pathfinder (ASKAP) in its commissioning phase to validate the performance of the telescope and to characterise the detected galaxy populations. This observation covers ∼48 deg2 with synthesised beam of 32.7 arcsec by 17.8 arcsec at 936MHz, and ∼39 deg2 with synthesised beam of 15.8 arcsec by 12.0 arcsec at 1320MHz. At both frequencies, the root-mean-square (r.m.s.) noise is ∼0.1 mJy/beam. We combine these radio observations with the GAMA galaxy data, which includes spectroscopy of galaxies that are i-band selected with a …

Teacher Candidate Immersion Into Bilingual/ Dual Language Classrooms In Largest Urban District In Texas, Bobbette M. Morgan, Criselda Garcia, John Jauregui

Teaching and Learning Faculty Publications

Prevailing teacher education reform initiatives call for preservice preparation to be "clinically rich" shifting the primary locus, and therefore location, of learning from within university walls to schools (National Council for Accreditation of Teacher Education, 2010; New York State Department of Education, 2011; U. S. Department of Education, 2009, 2011). In an effort of the largest school district in Texas to recruit our bilingual preservice teachers and for us to expose our students from the Rio Grande Valley to a highly populated urban setting, our students are invited to spend one week with host families and shadow an experienced teacher …

The Immediacy Of Genome Editing And Mitochondrial Replacement, Raymond C. O'Brien

Scholarly Articles

After human DNA was first defined in 1953, the parallel science of assisted reproductive technology achieved a successful human birth through in vitro fertilization in 1978. Science then went on to facilitate gestational surrogacy, banking human reproductive materials, such as embryos, and greater opportunities for couples and individuals to become parents. Fertility clinics were established throughout the world to help persons and couples achieve parenthood, contributing to a steady increase in babies born through assisted reproductive means. Gradually, both federal and state laws in the United States were enacted to collect data from the fertility clinics, mandate insurance coverage of …

Against The Tiers Of Constitutional Scrutiny, J. Joel Alicea, John D. Ohlendorf

Scholarly Articles

This year, for the first time in nearly a decade, the Supreme Court will return to the subject of the Second Amendment. New York State Rifle & Pistol Association, Inc. (NYSRPA) v. City of New York concerns a New York City licensing regime that, at the time the Court granted review, prohibited the transportation of any firearm outside city limits. (The City subsequently changed its licensing regime, perhaps in an effort to make the case go away before the Court could rule on the merits. It is unclear, at the time we write, whether that tactic will succeed.) Although most …

The Radiocarbon Record Of The Western Stemmed Tradition On The Southern Columbia Plateau Of Western North America, Thomas Brown, Daniel Mcgowan Gilmour, Paul S. Solimano, Kenneth Ames

Anthropology Faculty Publications and Presentations

The late Pleistocene–early Holocene archaeological record of the interior Pacific Northwest is dominated by what has been regionally referred to as the Western Stemmed Tradition (WST). While various efforts have attempted to clarify the chronology of this tradition, these have largely focused on data from the Great Basin and have been disproportionately preoccupied with establishing the beginning of the tradition due to its temporal overlap with Clovis materials. Specifically focusing on the Columbia Plateau, we apply a series of Bayesian chronological models to create concise estimates of the most likely beginning, end, and span of the WST. We then further …

Use Of Magnetic Resonance Image Registration To Estimate Displacement In The Human Earcanal Due To The Insertion Of In-Ear Devices, Simon Benacchio, Olivier Doutres, Arthur Varoquaux, Éric Wagnac, Arnaud Le Troter, Virginie Callot, Franck Sgard

Études primaires

In-ear devices are used in a wide range of applications for which the device's usability and/or efficiency is strongly related to comfort aspects that are influenced by the mechanical interaction between the device and the walls of the earcanal. Although the displacement of the earcanal walls due to the insertion of the device is an important characteristic of this interaction, existing studies on this subject are very limited. This paper proposes a method to estimate this displacement in vivo using a registration technique on magnetic resonance images. The amplitude, the location and the direction of the earcanal wall displacement are …

Chemical Synthesis Of Galacto-Oligosaccharides And Evaluation Of Their Prebiotic Properties, Pranpariya Ponpakdee

Chulalongkorn University Theses and Dissertations (Chula ETD)

Galacto-oligosaccharides (GOS) are composed of galactose and glucose between 2–8 units or disaccharide comprising 2 units of galactose linked by glycosidic bonds. GOS exhibits prebiotic activity and widely used in infant formula. Commercial GOS was achieved as mixture by enzymatic synthesis of lactose with β-galactosidase. Due to the nature of the enzymatic derived-GOS, the structure-activity relationship of GOS and prebiotic activity is mainly ambiguous. In this work, we presented the development towards a production of GOS by chemical synthesis starting from lactose. First, lactose was isolated from liquid whey with 3.90% w/v recovery. Lactose was then hydrolyzed to produce galactose …

Deep Patient Representation Of Clinical Notes Via Multi-Task Learning For Mortality Prediction, Yuqi Si, Kirk Roberts

Faculty, Staff and Student Publications

We propose a deep learning-based multi-task learning (MTL) architecture focusing on patient mortality predictions from clinical notes. The MTL framework enables the model to learn a patient representation that generalizes to a variety of clinical prediction tasks. Moreover, we demonstrate how MTL enables small but consistent gains on a single classification task (e.g., in-hospital mortality prediction) simply by incorporating related tasks (e.g., 30-day and 1-year mortality prediction) into the MTL framework. To accomplish this, we utilize a multi-level Convolutional Neural Network (CNN) associated with a MTL loss component. The model is evaluated with 3, 5, and 20 tasks and is …

Prairie Imperialists: The Indian Country Origins Of American Empire, Kate Bjork

Hamline Faculty and Staff Books and Publications

Traces the arc of American expansion by showing how the Army's conquests of what its soldiers called "Indian Country" generated a repertoire of actions and understandings that structured encounters with the racial others of America's new island territories following the War of 1898. Bjork follows the colonial careers of three Army officers from the domestic frontier to overseas posts in Cuba and the Philippines. The men profiled - Hugh Lenox Scott, Robert Lee Bullard, and John J. Pershing - internalized ways of behaving in Indian Country that shaped their approach to later colonial appointments abroad. Scott's ethnographic knowledge and experience …

Professionalism Kills The Trading Star: Explaining Member Participation In Trading Communities, Sabine Benoit, Jens Hogreve, Christina Sichtmann, Nicola Bilstein

Research Collection Lee Kong Chian School Of Business

Trading communities provide non-commercial members with an online platform on which to exchange goods. Its success depends on member participation; however, little is known about its drivers. Based on literature we identify five drivers. To capture their impact over time,we test a latent growth curve model with longitudinal data, comparing the effects at an initial point of time with their impact on the growth of member participation over three subsequent periods. The results show that providers’ responsiveness and community identification have a positive effect on the initial level, but not on growth. Members’ enjoyment has no level effect, but a …
