Implementing Technology In The Classroom: Assessing Teachers’ Needs Through The Use Of A Just-In-Time Support System, Alissa N. Anderson

Theses and Dissertations (Comprehensive)

Given the importance of computer technology in classrooms today, it is crucial to identify the types of supports that will facilitate teachers’ effective implementation of technology. Ten teachers (four kindergarten, four grade one, and two grade one/two) received just-in-time support while introducing a reading software program in their class. An additional 12 teachers (four kindergarten, seven grade one, and one grade two) were exposed to the software, but did not receive just-in-time support. Both quantitative and qualitative analyses of instructional sessions were conducted in order to determine the kinds of support that teachers required throughout the intervention. Results provided an …

Leaders In Conflict: Diefenbaker, Kennedy, And Canada’S Response To The Cuban Missile Crisis, Matthew Gurney

Theses and Dissertations (Comprehensive)

While the Cuban Missile Crisis has received a tremendous amount of attention from American scholars, in Canada the historiography concerning the Crisis is quite limited, with few monographs devoted to it. Typically the Crisis might receive a few pages of attention, perhaps a chapter in a book concerned with other topics. This historiographical “blind spot” has allowed misconceptions concerning Canada’s diplomatic and military participation in the Crisis to persist in this country’s collective memory of the Crisis, which is a disservice not only to Canada’s national heritage, but to the thousands of men and women who strove to prepare Canada …

Understanding Tourist-Host Interactions And Their Influence On Quality Tourism Experiences, Tiffanie L. Skipper

Theses and Dissertations (Comprehensive)

In response to the rise in visitor harassment in tourist destinations, there is a need to further our understanding of its impacts on the tourist experience. The purpose of this study was to understand tourist-host interactions in the context of harassment and its influence on overall quality of the tourism experience. Tourist attitudes towards hosts is an under researched topic in the academic literature. Thus, this thesis makes use of the social exchange theory, tourism development cycles, and the concept of segmentation (traditionally used to explain residents’ attitudes towards tourism/tourists), to help understand tourists’ attitudes towards hosts. Similarly, there are …

Transnational Chowtal: Bhojpuri Folksong From North India To The Caribbean, Fiji, And Beyond, Peter L. Manuel

Publications and Research

In mid-February of 2007, I attended some lively sessions of chowtal (Hindi, cautāl), a boisterous Bhojpuri folk song genre, in a Hindu temple in a small town a few hours from Banaras (Varanasi), North India. The following weekend I was singing chowtal, in an identical style, with an Indo-Guyanese ensemble in Queens, New York City. In the subsequent season of the vernal Holi (Hindi, holī) festival, in March 2008, I found myself singing along with a group of Indo-Fijians in Sacramento, California, as they performed a similar version of one of the same chowtal songs. Despite the nearly identical styles …

Nafta Chapter 11 As Supraconstitution, Stepan Wood, Stephen Clarkson

All Faculty Publications

More and more legal scholars are turning to constitutional law to make sense of the growth of transnational and international legal orders. They often employ constitutional terminology loosely, in a bewildering variety of ways, with little effort to clarify their analytical frameworks or acknowledge the normative presuppositions embedded in their analysis. The potential of constitutional analysis as an instrument of critique of transnational legal orders is frequently lost in methodological confusion and normative controversy. An effort at clarification is necessary. We propose a functional approach to supraconstitutional analysis that applies across issue areas, accommodates variation in kinds and degrees of …

Tax Expenditures To Limit The Growth Of Carbon Emissions In Canada: Identification And Evaluation, David G. Duff, E. Ian Wiebe

All Faculty Publications

Unlike the U.S., which relies heavily on tax expenditures as instruments of energy and climate change policy, Canada has introduced very few such tax expenditures, relying instead on voluntary initiatives, direct subsidies, and limited regulatory measures to limit carbon emissions. This paper identifies and evaluates the most prominent tax expenditures in Canada to limit the growth of carbon emissions. As background to this inquiry, Part II reviews Canadian experience with carbon emissions over the last two decades and the limited government response to this growing problem. Part III identifies the most prominent tax expenditures that Canadian governments have introduced in …

The Relationship Between Rights And Responsibilities, Liora Lazarus, Benjamin J. Goold, Rajendra Desai, Qudsi Rasheed

All Faculty Publications

This report considers the relationship between rights and responsibilities within the context of the ongoing debate on a Bill of Rights and Responsibilities. In keeping with the commitment of the Green Paper 2009 to ensure that any increased emphasis on responsibilities in such a Bill will not erode the protection of rights, this report highlights the potential risks associated with incorporating responsibilities into Britain’s constitutional framework.

Shaping Attitudes About Homosexuality: The Role Of Religion And Cultural Context, Amy Adamczyk, Pitt Cassidy

Publications and Research

Across the globe, the debate over homosexuality continues, with great variation in public opinion about the acceptability of homosexuality, laws regulating same-sex unions and penalties for homosexual sex behaviors. Religion is often seen as an important predictor of attitudes about homosexuality. However, cross-national differences in cultural orientations suggest that the role religion has in explaining homosexual attitudes may depend on a nation’s cultural context. In this study, we merge ideas from cultural sociology and religious contextual effects to explain cross-national variation in public opinion about homosexuality. Using data from the fourth wave of the World Values Survey and Hierarchical Modeling …

Remedies, Antitrust Law, And Microsoft: Comment On Shapiro, Keith N. Hylton

Faculty Scholarship

The subject of remedies is a relatively under-theorized area of antitrust law, and Professor Shapiro has done the antitrust community a great favor by offering some innovative and useful theoretical insights on the design of antitrust remedies. He applies his theoretical insights to the Microsoft III case to reach the conclusion that the remedies adopted were inadequate to restore competition in the market for software platforms. In this review, I will offer additional theoretical insights on remedies and explain my reasons for rejecting his conclusions on Microsoft III.

Relating Fractal Dimension To Branching Behaviour In Filamentous Microorganisms, David Barry, Onwuarolu Ifeyinwa, Shauna Mcgee, Raymond Ryan, Gwilym Williams, Jonathan Blackledge

Articles

The productivity of an industrial fermentation process involving a filamentous microbe is heavily dependent on the morphological form adopted by the organism. The development of systems capable of rapidly and accurately characterising morphology within a given process represents a significant challenge to biotechnologists, as the complex phenotypes that are manifested are often not easily quantified. Conventional parameters employed in these analyses are of limited value, as they reveal little about the specific branching behaviour of the organism, which is an important consideration given the demonstrated link between branching frequency and metabolite production. More recently, fractal geometry has been employed in …

Scattering From A Tenuous Random Medium With Applications In Optics, Jonathan Blackledge

Articles

Mathematical models for the scattering of light (and other radiation) tend to fall into two categories based on a weak field condition (single scattering processes) or a strong field condition (multiple scattering processes). In the latter case, the complexity of deterministic models coupled with available solutions often fail to provide results that are of value to engineering systems (e.g. imaging systems). For this reason, multiple scattering problems are often approached using stochastic modelling methods whose foundations lie in random walk theory where the amplitude and phase of the scattered field are taken to conform to an appropriate statistical process and …

When The Lawyer Knows The Client Is Guilty: Client Confessions In Legal Ethics, Popular Culture, And Literature, Michael Asimow, Richard H. Weisberg

Articles

The article explores the ethical dilemma faced by criminal defense lawyers when they know their client is factually guilty but the client insists on a vigorous defense. It examines the tension between the lawyer’s duty of zealous representation and the duty of candor toward the court, proposing a compromise that allows lawyers discretion to choose between strong or weak adversarial approaches based on the context. The analysis draws on historical cases, such as the Courvoisier case of 1840 and the modern case of Steven Feldman, as well as insights from popular culture and literary sources, to argue that the discretionary …

Therapeutic Ultrasound Angioplasty: The Risk Of Arterial Perforation. An In Vitro Study, Mark Wylie, Garrett Mcguinness, Graham Gavin

Conference Papers

The use of therapeutic ultrasound delivered via small diameter wire waveguides may represent an emerging minimally invasive approach in the treatment of chronic total occlusions (CTOs), calcified and fibrous plaques. The distal-tip mechanical vibrations (typically 0-210 μm peak-to-peak) have been reported to debulk rigid calcified and fibrous tissues while healthy elastic arterial tissue remains largely unaffected. The risk of arterial (healthy tissue) perforation with energized waveguides is not fully understood. An ultrasonic apparatus capable of delivering a range of wire waveguide distal-tip displacements, up to 80 μm peak-to-peak (p-p), at an operational frequency of 22.5 KHz (+/- 6%) has been …

Ultrasonic Angioplasty: Assessing The Risk Of Arterial Perforation, Mark Wylie, Garrett Mcguinness, Graham Gavin

Conference Papers

Atherosclerosis is a cardiovascular disease that effects large and medium muscular arteries (such as coronary and iliac) and also large elastic arteries (such as aorta) [1]. It causes thickening of the arterial wall and over time can result in a completely blocked artery or chronic total occlusion (CTO). While the majority of atherosclerotic lesions can be attempted by typical Percutaneous Transluminal Coronary Angioplasty (PTCA) such as balloon and stent implantation, calcified CTOs are often problematic as they do not lend themselves to be accessed by the guidewire which is required to implant the balloon and stent. Excessive guidewire pushing force …

Acceptance Of Evolution Increases With Student Academic Level: A Comparison Between A Secular And A Religious College, Guillermo Paz-Y-Mino C., Avelina Espinosa

Arts & Sciences Faculty Publications

Acceptance of evolution among the general public, high schools, teachers, and scientists has been documented in the USA; little is known about college students’ views on evolution; this population is relevant since it transits from a high-school/parent-protective environment to an independent role in societal decisions. Here we compare perspectives about evolution, creationism, and intelligent design (ID) between a secular (S) and a religious (R) college in the Northeastern USA. Interinstitutional comparisons showed that 64% (mean S + R) biology majors vs. 42/62% (S/R) nonmajors supported the exclusive teaching of evolution in science classes; 24/29% (S/R) biology majors vs. 26/38% (S/R) …

The Paradox Of Exclusion Within Equity: Interrogating Discourse At The Canadian Human Rights Tribunal, Delores V. Mullings

Theses and Dissertations (Comprehensive)

Employment discrimination has been a challenge in Canada for many groups and for government agencies who propose to adhere to a human rights agenda. To address this concern, the federal government initiated various anti-discriminatory policies and programs to counteract employment discrimination for four designated groups: Aboriginal people, “visible minorities,” women, and people with disabilities. The Employment Equity Act and the Canadian Human Rights Act were the legislation, and the Canadian Human Rights Commission and the Canadian Human Rights Tribunal the institutions designed to deal with employment discrimination for federal employees. When employees file a claim, it is initially processed at …

Responding To Change In A Northern Aboriginal Community (Fort Resolution, Nwt, Canada): Linking Social And Ecological Perspectives, Sonia Darienne Wesche

Theses and Dissertations (Comprehensive)

Human and environmental systems in the circumpolar north are particularly affected by the Earth’s changing climate, thus acting as a bellwether for other parts of the globe. Rural indigenous communities are most visibly impacted due to their close relationship with the land. These challenges are compounded by socio-economic transformations typical of peripheral communities within a larger, centrally governed system.

This dissertation links a community-based study of environmental change in Fort Resolution, Northwest Territories, Canada to evolving adaptation science. The study was prompted by local concern about changing environmental conditions caused by climatic, hydrological and resource development drivers. Its collaborative research …

BACKGROUND: Glioblastoma multiforme (GBM) is the most aggressive primary brain tumor that carries a 5-y survival rate of 5%. Attempts at eliciting a clinically relevant anti-GBM immune response in brain tumor patients have met with limited success, which is due to brain immune privilege, tumor immune evasion, and a paucity of dendritic cells (DCs) within the central nervous system. Herein we uncovered a novel pathway for the activation of an effective anti-GBM immune response mediated by high-mobility-group box 1 (HMGB1), an alarmin protein released from dying tumor cells, which acts as an endogenous ligand for Toll-like receptor 2 (TLR2) signaling …

Fatigue Of Friction Stir Welded Lap Joints With Sealants, Kenneth Doering

Masters Theses

"A lack of understanding of corrosion fatigue in friction stir welded aluminum joints prevents friction stir welding from being implemented in aerospace applications. Fatigue testing reveals a 60-75% reduction in the fatigue life of friction stir welded aluminum lap joints immersed in 3.5% NaCl solution (corrosion fatigue) compared with that of lap joints tested in ambient air. The loss in fatigue life is attributed to accelerated fatigue cracking due to hydrogen environment embrittlement. Two polymer sealant candidates are investigated: silicone rubber and nylon-11. Both sealant candidates can be applied prior to welding and seal the faying surface gaps in lap …

Media Subpoenas: Impact, Perception, And Legal Protection In The Changing World Of American Journalism, Ronnell Andersen Jones

Faculty Scholarship

Forty years ago, at a time when the media were experiencing enormous professional change and a surge of subpoena activity, First Amendment scholar Vincent Blasi investigated the perceptions of members of the press and the impact of subpoenas within American newsrooms in a study that quickly came to be regarded as a watershed in media law. That empirical information is now a full generation old, and American journalism faces a new critical moment. The traditional press once again finds itself facing a surge of subpoenas and once again finds itself at a time of intense change—albeit on a different trajectory—as …

Articles

All new technologies have an inherent risk, which is typically assessed alongside the development of applications of the technology. This is also the case for nanotechnology: a key concern in the case of engineered nanomaterials (ENMs) is that due to their very small size, NMs can reach areas such as the cell that are inaccessible to other materials, such as implants and drugs. As a result of their large surface area, NMs may be more reactive than other larger materials. The large physical and chemical variability of NMs, and the fact that small changes can have large consequences, mean that …

Optical Properties Of Silica-Mfi Doped Acrylamide-Based Photopolymer, Tzvetanka Babeva, Rosen Todorov, Svetlana Mintova, Temenujka Yovcheva, Izabela Naydenova, Vincent Toal

Articles

The optical properties of acrylamide-based photopolymer doped with pure silica MFI-type zeolites are studied by refractometric and spectrophotometric means. Dynamic Light Scattering and Transmission Electron Microscopy are used for zeolite characterization and laser refractometry and White Light Interferometric profilometry are used for surface characterization of the composites. Refractive indices and absorption coefficients of composites are determined from their transmittance and reflectance spectra. The calculated dispersion curves are further used for deriving the zeolites refractive index and porosity and the latter compared to the values of total pore volume obtained from N2-sorption measurements. The impact of the doping level on the …

Second-Hand Smoke Exposure In Cars And Respiratory Health Effects In Children, Patrick J. Goodman, Z. Kabir, Luke Clancy, P.J. Manning, J. Holohan, S. Keogan

Articles

We examined potential associations of ever asthma, and symptoms of wheeze (past 12 months), hay fever, eczema and bronchitis (cough with phlegm) among school children exposed to second-hand smoke (SHS) in cars, using a modified Irish International Study of Asthma and Allergies in Childhood (ISAAC) protocol. 2,809 children of 13–14 yrs old and who selected randomly from post-primary schools throughout Ireland completed the 2007 ISAAC self-administered questionnaire. Adjusted OR (adjusted for sex, active smoking status of children interviewed and their SHS exposure at home) were estimated for the associations studied, using multivariable logistic regression techniques. Overall, 14.8% (13.9% in young …

Silicone Rubber Passive Samplers For Water Quality Monitoring Of Persistent Organic Pollutants In The Marine Environment, Susan O'Hara

Masters

Polychlorinated Biphenyls (PCBs) and Polyaromatic Hydrocarbons (PAHs) are internationally considered as persistent organic pollutants (POPs) which can be mutagenic, carcinogenic and may accumulate in aquatic organisms and potentially in the human chain. PCBs and PAHs are thus listed as priority pollutants in the Water Framework Directive (WFD) and under the Convention for the protection of the Marine Environment of the North-East Atlantic (Oslo Paris Convention: OSPAR). Currently most marine monitoring programmes involving such compounds rely on the collection and analysis of discrete water/sediment grab samples or on the analysis of filter feeding indicator organisms e.g. mussels. Such measurements can provide …

Transcriptional Regulation Of Soluble Guanylyl Cyclase, Ashling Hampson

Masters

Each year cardiovascular disease causes over 4.3 million deaths in Europe and is the cause of nearly one in three deaths in the US. Nitric oxide (NO) is a toxic atmospheric gas which exists in tissues as a biological product of mammalian cells. It has been used to manage cardiovascular disease for over a century and to this day remains an important treatment option in cardiovascular medicine. NO is produced by many cells in the body including vascular endothelial cells. Because of its importance in vascular function, abnormal production of NO, which occurs in different disease states, can adversely affect …

Symposium: Reflections On Tinker, Tinker Turns 40: Freedom Of Expression At School And Its Meaning For American Democracy - April 16, 2009 - Symposium: Foreword , Mary Beth Tinker

American University Law Review

Mary Beth Tinker recounts her upbringing and her family’s involvement in important issues of their day. Tinker discusses how her family’s commitment to social justice was shaped by her parents religious values, and how this shaped their commitments to civil rights, ultimately leading to their protesting ongoing injustices. In particular, Tinker discusses how she, her siblings, and friends wore black armbands calling for a Christmas Truce in the Vietnam War and how the case that went before the Supreme Court was one of a series of events in her family’s journey for equality.
