Barack Obama, Margarita Lopez Torres, And The Path To Nomination, Ellen D. Katz

Articles

Operating within these regimes, Obama was able to mount a credible--and ultimately successful--challenge to the leadership's choice for the nomination while Lopez Torres could not. This article offers an explanation why. It argues that Obama succeeded where Lopez Torres failed because the nomination process Obama traversed was more penetrable and more contestable than the one Lopez Torres faced.

Microfinance Managers Consider Online Funding: Is It Finance, Marketing, Or Something Else?, Deborah Burand

Articles

Online platforms are changing the way we engage with the world. Facebook links, eBay auctions, ePal chats, even Second Life avatars—these are all online platforms that connect people, ideas, products, and markets. These platforms shape who we connect with as well as how we connect. This concept extends to philanthropy: Online philanthropy is changing the nature of how and where people give.1 An outgrowth of online philanthropy is online social investing. Kiva.org is one of the best known online lending and investment platforms. Since its launch in 2005, Kiva has grabbed the attention (and wallets) of over 350,000 online lenders, …

The Future Of American Labor And Employment Law: Hopes, Dreams, And Realities, Theodore J. St. Antoine

Articles

In many respects the US is a deeply conservative country. Unique among the major industrial democracies of the world, it imposes the death penalty, provides no national health insurance, fixes a high legal drinking age, and subscribes to the doctrine of employment at will. Perhaps not surprisingly, its labor movement is also one of the most conservative on earth, eschewing class warfare and aiming largely at the bread-and-butter goal of improved wages, benefits, and working conditions. Yet American employers have generally never been as accepting of unionization as their counterparts in other countries (Bok 1971; Freeman and Medoff 1984). Over …

Prosecuting Worker Endangerment: The Need For Stronger Criminal Penalties For Violations Of The Occupational Safety And Health Act, David M. Uhlmann

Articles

A recent spate of construction deaths in New York City, similar incidents in Las Vegas, and scores of fatalities in recent years at mines and industrial facilities across the country have highlighted the need for greater commitment to worker safety in the United States and stronger penalties for violators of the worker safety laws. Approximately 6,000 workers are killed on the job each year1—and thousands more suffer grievous injuries—yet penalties for worker safety violations remain appallingly small, and criminal prosecutions are almost non-existent. In recent years, most of the criminal prosecutions for worker safety violations have been brought by the …

Can Bundled Discounting Increase Consumer Prices Without Excluding Rivals?, Daniel A. Crane, Joshua D. Wright

Articles

Since we abhor suspense, we will quickly answer the question our title poses: No. As a general matter, bundled discounting schemes lower prices to consumers unless they are predatory—that is to say, unless they exclude rivals and thereby permit the bundled discounter to price free of competitive restraint. The corollary of this observation is that bundled discounting is generally pro-competitive and pro-consumer and should only be condemned when it is capable of excluding rivals. We pose and answer this question because it is at the heart of Section VI of Professor Elhauge’s provocative draft article which is the subject of …

Automatic Video Classification, Don Jayakody

Master's Projects

Within the past few years video usage has grown in a multi-fold fashion. One of the major reasons for this explosive video growth is the rising Internet bandwidth speeds. As of today, a significant human effort is needed to categorize these video data files. A successful automatic video classification method can substantially help to reduce the growing amount of cluttered video data on the Internet. This research project is based on finding a successful model for video classification. We have utilized various schemes of visual and audio data analysis methods to build a successful classification model. As far as the …

Globalization Mitigated: Human Rights, Corporations, And The New World Economy, M. Raymond Izarali

Theses and Dissertations (Comprehensive)

In this thesis, I argue for a set of basic human rights to constrain the practices of corporate entities in the context of economic globalization. These basic rights are derived through a concrete interpretation of specific articles in the Universal Declaration of Human Rights. My focus is on constructing a middle-ground approach to economic globalization by building on the work of Peter Singer, Onara O’Neill, John Bishop, and Leo Groarke, but with particular emphasis on Groarke’s notion of a mitigated capitalism. The underlying objective of the middle ground is to secure globalization’s benefits and circumvent its harms. As I am …

Computer Integration In Elementary And Secondary Schools: Variables Influencing Educators, Julie Mueller

Theses and Dissertations (Comprehensive)

Given the prevalence of computers in education today, it is critical to understand teachers’ perspectives regarding computer integration in their classrooms. Research identifying stages of implementation, and literature identifying barriers and supports, fall short of explaining what variables impact an educator’s ultimate decision to integrate technology in their instruction. The current research surveyed a heterogeneous sample of 185 elementary and 204 secondary teachers in order to provide a comprehensive summary of teacher characteristics and variables that discriminate teachers who integrate technology from those who do not. Discriminant Function Analysis (DFA) identified the following variables as making unique contributions to discriminating …

Neural And Behavioural Effects Of The Ginkgo Biloba Leaf Extract Egb 761, Elham Satvat

Theses and Dissertations (Comprehensive)

Numerous studies have documented the cognitive-enhancing effects of standardized Ginkgo biloba leaf extracts (Ginkgo) both in humans and in rodents. In addition to its antioxidant and platelet-activating factor inhibiting properties, Gingko has been shown to protect cellular membrane fluidity, to enhance cerebral blood flow and microcirculation, and to modulate cholinergic system functioning, properties that have been suggested to underlie its cognitive-enhancing effects. However, the possible neurogenic-enhancing effects of Ginkgo on adult hippocampal neurogenesis as a possible mechanism underlying its nootropic effects have not been evaluated. The experiments discussed in the present thesis assessed such a possibility.

The Rules Of Engagement: German Women And British Occupiers, 1945–1949, Barbara Smith

Theses and Dissertations (Comprehensive)

This dissertation is a document based administrative study of the British occupation of Germany, 1945–49, and its impact on specific areas of the lives of German women who were living in the British zone. The study examines the effect of British occupation policy on the regulation of marriage, prostitution and venereal disease, and German women’s organizations. British occupation strategies were unique; although the British worked with the Americans on many levels they maintained separate policy approaches. The British brought their own social perspectives and systems to Germany and attempted to impose them on German social and civil procedures. German women …

Saltwater Sacraments And Backwoods Sins: Contemporary Atlantic Canadian Literature And The Rise Of Literary Catholicism, Andrew Peter Atkinson

Theses and Dissertations (Comprehensive)

In the 1990s, Canadian readers were offered a new literary trend: the Atlantic Canadian Catholic novel. In this dissertation, I examine works from six authors whose writing reflects the scope of this trend and I argue for a consideration of their collective impact on our social imaginary. The bulk of my argument is devoted to an examination of the Catholic religious content in the five novels and one memoir: David Adams Richards’ Bay of Love and Sorrows (1998); Ann-Marie MacDonald’s Fall on Your Knees (1996); Lynn Coady’s Strange Heaven (1996); Wayne Johnston’s Baltimore’s Mansion: A Memoir (1999); Patrick Kavanagh’s Gaff …

Keeping Kids Safe In Custody: Youths’ Perception Of Safety While Incarcerated In Canada, Judy Finlay

Theses and Dissertations (Comprehensive)

Keeping Kids Safe (KKS) is a study that presents an integrated model to demonstrate that the interaction between the predisposition of the youth and the institutional environment acts to promote or deter safety among incarcerated youth. The study illustrates that the peer subculture that produces a spectrum of violence within the institution is dependent on both the extra-custody attributes of the youth that affect his attitudes, beliefs and behaviours and on the critical influence of institutional attributes like program resources, staff/youth interactions and practices of social control. A predisposition that includes child maltreatment and exposure to domestic violence was used …

Commanding The Green Centre Line In Normandy: A Case Study Of Division Command In The Second World War, Angelo N. Caravaggio

Theses and Dissertations (Comprehensive)

This thesis examines the experiences of the 4th Canadian Armoured Division as it prepared for and carried out its role in the battle of Normandy and the libeation of France in 1944. The factors that limmited opportunities to practice the formation in large-scale exercises are noted as are the methods used by the General Officer Commanding, Major-General George Kitching, to compensate for the limitations. This thesis argues that through the development of an effective commander-staff dynamic Kitching, his staff and his subordinates commanders, were able to meet the challenges and chaos of combat in the final stages of the Normandy …

Illusion Of Coexistence: The Waldorf Schools In The Third Reich, 1933–1941, Karen Priestman

Theses and Dissertations (Comprehensive)

From 1933 to 1941, the eight existing Waldorf schools in Germany were forced to close. As an alternative system of education, they were considered a threat to National Socialism. Yet, they were not systematically nor uniformly brought into line with the Nazi state through the process of Gleichschaltung. Very few studies address the history of the Waldorf schools under National Socialism, and those that do are invariably written by members of the Waldorf school community. By examining correspondence between the Waldorf school administrators and Nazi officials, this study helps to fill the void. This investigation reveals that the personalities …

Moving Beyond The Surface: Ethics Education In Canadian Social Work Bachelor Programs, Susan Lynn Hardie

Theses and Dissertations (Comprehensive)

This thesis is an exploratory analysis of: “How Canadian schools offering bachelor programs attend to social work ethics education in the 21st century?” A concurrent triangulation mixed method research design was chosen to draw upon the strengths of quantitative and qualitative analysis, and minimize the limitations of each method. Deans and Directors at the thirty-two Faculties, Schools and Departments of Social Work with bachelor social work programs in Canada were contacted and requested to identify an expert in social work ethics education to partake in this research. Fifty-three (53%) of the schools had educators either complete the survey and/or engage …

Methodological Note: On Using Personal Digital Assistants (Pdas) For Survey Administration In The Study Of Youth Development, Mona M. Abo-Zena, Amy Eva Alberts Warren, Sonia S. Isaac, Dan Du, Erin Phelps, Richard M. Lerner, Robert W. Roeser

Psychology Faculty Publications and Presentations

Applied developmental scientists face the challenge of identifying research methods that enable the efficient collection of data from youth of diverse social backgrounds (e.g., ethnic. racial, religious, economic) and varying levels cognitive-linguistic and attentional skills. In addition, because access to youth during school time is often limited by educators’ desire to preserve instructional time, finding methodologies to collect data from youth that are highly efficient, and also those that are feasible in less structured settings, are needed. This article outlines some of the benefits and limitations of using a voice enhanced survey delivered on a personal digital assistants (PDA) as …

Phylogeny, Adaptive Radiation, And Historical Biogeography In Bromeliaceae: Insights From An Eight-Locus Plastid Phylogeny, Thomas J. Givnish, Michael H. J. Barfuss, Benjamin Van Ee, Ricarda Riina, Katharina Schulte, Ralf Horres, Philip A. Gonsiska, Rachel S. Jabaily, Darren M. Crayn, J. Andrew Smith

Biological Sciences Faculty Publications

Premise: Bromeliaceae form a large, ecologically diverse family of angiosperms native to the New World. We use a bromeliad phylogeny based on eight plastid regions to analyze relationships within the family, test a new, eight-subfamily classification, infer the chronology of bromeliad evolution and invasion of different regions, and provide the basis for future analyses of trait evolution and rates of diversification.

Methods: We employed maximum-parsimony, maximum-likelihood, and Bayesian approaches to analyze 9341 aligned bases for four outgroups and 90 bromeliad species representing 46 of 58 described genera. We calibrate the resulting phylogeny against time using penalized likelihood applied …

Secondary Traumatic Stress: The Hidden Trauma In Child And Youth Counsellors, Michelle Linda Bloom

Theses and Dissertations (Comprehensive)

The current research study was conducted to establish evidence based research identifying Secondary Traumatic Stress (STS) in Child and Youth Counsellors (CYCs). 161 CYCs participated in an online survey responding to both demographic questions and Bride’s (1999) Secondary Traumatic Stress Scale (STSS). Data analysis included both descriptive and inferential testing. Scoring of the STSS revealed that 66.1% of the CYCs sampled experienced some level of STS. The overall mean score is 33.65 suggesting that CYCs experienced a mild level of STS. An independent group t-test indicated that CYC’s who were exposed to children and youth’s traumatic experience 1 to 3 …

The Influence Of Concurrent Visual Feedback During Treadmill Training In Parkinson’S Disease, Rose Ellen Johnston

Theses and Dissertations (Comprehensive)

Walking is an exercise that has been thought to benefit Parkinson’s disease (PD). In a laboratory setting treadmills have been employed to successfully improve certain aspects of gait in PD (Cakit et al., 2007, Fisher et al., 2008, Herman et al., 2007, Miyai et al., 2000, Miyai et al., 2002, Pohl et al., 2003). Research has also indicated that walking with visual cues can improve aspects of gait that are impaired in PD (Azulay et al., 1999, Bagely et al., 1997, Nieuwboer et al., 2007), however, the integration of visual cues and treadmill training has yet to be studied. Thus, …

Internal And External Triggers For Action, Shannon Matkovich

Theses and Dissertations (Comprehensive)

When the self paced preparation of an action is interrupted by a stimulus prompting the same motor response there is an increase in the reaction time to the stimulus as compared to an external or simple reaction time (SRT) condition (Obhi & Haggard, 2004). Previous studies have suggested that this cost is not attributable to perceptual or attentional factors. Therefore, to investigate the source of this RT cost we varied the motor demands of movements in Experiments one and two. Results indicated that the level of motor programming demands did not influence the RT cost in these experiments. While RTs …

Non-Biological Caregivers’ Experiences Of Fetal Alcohol Spectrum Disorder (Fasd) Support Groups, Sharon Porty

Theses and Dissertations (Comprehensive)

Caregivers of children with Fetal Alcohol Spectrum Disorder (FASD) are an extremely valuable resource, and supporting a stable and nurturing home environment may be the most achievable intervention to improve the child’s prognosis. Very little research has been done to explore effective interventions that focus on the FASD caregiver, rather than the child, for the purposes of preventing caregiver burnout and placement breakdown. The central purpose of this study is to explore non-biological parent caregivers’ experiences of FASD caregiver support groups in order to capture a better understanding of the value of this resource as one part of a continuum …

Exploring Newcomer Settlement And Integration Supports In Brantford, And Brant-Haldimand-Norfolk Counties: Community-Based Participatory Research, Bharati Sethi

Theses and Dissertations (Comprehensive)

Much of the literature on recent immigrants focuses on a needs analysis from a deficit model where primarily formal services and programs related to employment issues are analyzed from a post-positivist or interpretivist framework. Using a strength-based approach this study examined other settlement issues including employment that are vital to the long-term viability of newcomers and the host society such as access to education, training (language and/or vocational), health care, and social network. Using Community Based Participatory Research (CBPR) philosophical framework and methodology, data were generated from various sources—quantitative and qualitative text in the survey questionnaire (service providers and newcomers), …

Voices Of Anorexia Uncovered: The Healing Journey Unveiled, Elisha Van Harte

Theses and Dissertations (Comprehensive)

Eating disorders have the highest mortality rate of any psychiatric illness. The current rate of anorexia nervosa is 1% in North America, representing approximately three million cases. Consequently, this illness has attracted a growing body of research and treatment. Current research in the field has focused primarily on the etiology of the illness. Furthermore, outcome studies are primarily quantitative in nature and have indicated that there is no treatment modality that consistently results in longitudinal recovery. What appears to be absent from the literature is the exploration of the recovery process from the perspective of those who have recovered. The …

The Sexual Health Education Experiences And Needs Of Immigrant Women In Kitchener-Waterloo, Stefani Burosch

Theses and Dissertations (Comprehensive)

In Canada, the sexual health education needs of individuals beyond their adolescent years are often overlooked. For immigrant women, silences around issues of adult sexual health are compounded by the perception of mystery and taboos surrounding minority women and sexuality. In exploring the experiences and needs of adult immigrant women related to sexuality and sexual health education in Kitchener-Waterloo—two mid-size cities located within the Waterloo Region in southern Ontario—this study sought to create space for dialogue and to bridge the perceived cultural divide on issues of sexual health that often arises between individuals from different cultural backgrounds.

Using a qualitative …

Assessing Tangible Support Efforts In English Canadian Christian Church Communities, Dana M. Friesen

Theses and Dissertations (Comprehensive)

This thesis was inspired by one family’s need for support and how it came to be expressed and negotiated within their faith community. The purpose of this study was to survey English-speaking, Christian congregations across Canada in order to discover the range of tangible social supports available to congregants. Tangible supports were defined as practical (i.e. acts of service), material, and social/emotional support. An important component in this study was to identify strengths and gaps in the development and mobilization of congregational supports, as expressed by church leaders. Another important aspect included the exploration of church leaders’ and their congregations’ …

Piecing Together The Puzzle Of Autism: Aspects Of Its Effects On Children With The Condition And Their Caregivers, Roula Markoulakis

Theses and Dissertations (Comprehensive)

As one of the most prevalent developmental disorders, extensive research exists concerning Autism Spectrum Disorders (ASD). However, gaps are still evident in a number of areas. Information pertaining to any costs and benefits associated with the experience of caring for a child with autism is inadequate. In Study 1, the lived experiences of married female primary caregivers of children with autism were explored, specifically by examining the costs and benefits of caregiving and its influence on the women’s situations. Furthermore, motor control deficits are apparent in many children with high functioning autism (HFA) and Asperger syndrome (AS), but need to …

Understanding Best Practices For Community Engagement In Municipal Contexts, Sherry Mcgee

Theses and Dissertations (Comprehensive)

Engaging citizens in decision making has long been understood as part of the democratic process, most commonly recognized as electoral votership. In recent decades, the benefits of providing citizens a variety of opportunities for community engagement (CE) have been documented. Currently, few studies have explored the role of municipal government in engagement processes, and how engagement should be contextualized within municipal policy structures and practices. The City of Kitchener, located in Ontario, Canada is in the process of formalizing engagement practices through policy. In partnering with the City of Kitchener, five interviews were conducted with four Canadian municipalities and one …

Metabolic And Molecular Approaches To The Study Of Bacterial Communities In Wetlands Of The Alberta Athabasca Oil Sands Region, Jessica Dawn Morrison

Theses and Dissertations (Comprehensive)

Bacterial communities in wetlands from the Athabasca region (Alberta, Canada) were surveyed and their utility as bio-indicators for wetland reclamation was assessed. Sediment samples were collected from wetlands categorized as: (1) natural (off mining leases), (2) reference (on mining sites but not directly impacted by oil sands processed material (OSPM)), and (3) OSPM (directly affected by OSPM). Wetlands of the latter two groups ranged in age from 11 to 24 years. Analysis involved community level physiological profiling (CLPP) with BIOLOG™ EcoPlates, and denaturing gradient gel electrophoresis (DGGE). Multivariate analysis applied to data from both techniques revealed differences in the bacterial …

An Examination Of Intercollegiate Athletic Injury Tracking Systems Within Canadian Universities, Andrew D. Ross

Theses and Dissertations (Comprehensive)

Information regarding the practice of athletic injury tracking within Canadian intercollegiate institutions has been relatively deficient. The study aimed to assess the current status of athletic injury tracking systems (AITS) in Canadian universities within the Canadian Interuniversity Sport Association (CIS). A secondary purpose was to obtain data from therapists within Canadian Universities, to identify and analyze issues, benefits, barriers and obtain information regarding how athletic injury tracking methods are conducted. This was achieved by obtaining data regarding the current state of AITS in CIS institutions, clinical demographics, athletic therapists and/or physiotherapists’ opinions regarding the pro’s and con’s of athletic injury …

The Effect On Response Complexity On Task-Switching Behaviour, Christina Shepherd

Theses and Dissertations (Comprehensive)

Research on task-switching has shown that when participants are asked to switch between two different tasks, they are slower than when they repeat the same task. These costs have also been shown to increase when the previous response is repeated; however, very little has been done to investigate the role of response complexity in this relationship. We manipulated response complexity by increasing both the number of stimulus-response pairs and the number of individual response components. We hypothesized that increased response complexity would increase both the switch costs and the response repetition effect. Results indicated that increasing the number of S-R …
