Cryptography Export Controls - Canada's Dichotomous Cryptography Policy, Paul Bates

Canadian Journal of Law and Technology

The effort to erect strong legal barriers to trans-national distribution of cryptography has significant gaps because strong cryptography can be obtained and used within Canada without legal restrictions. This paper advocates that Canada should exercise its discretion under the WA to diminish, not fortify, the restrictions of the export control regime.

In-Group/Out-Group Dynamics Of Native American Mascot Endorsement, John Gonzalez

Theses and Dissertations

The use of Native American names and mascots by professional and college sports teams has become a controversial issue. However, very litde research has investigated attitudes towards Native Americans, regarding relationships between team names and mascots on prejudice and discrimination. This study proposed that the multiple social categories created by manipulating the endorsement/opposition of Native mascots by Native and White college students at a university with a Native mascot, would allow for the identification of possible prejudice and discrimination based on race and the mascot issue. It was hypothesized that the manipulation of Native American Mascot Endorsement (NAME) in Native …

Incidence And Clinical Predictors Of Risk Factors For Inappropriate Shock In Patients With Implantable Cardioverter-Defibrillators, Shu-Ling Lo Phd

Dissertations

Sudden cardiac death (SCD) is a major unresolved medical problem worldwide. Although Implantable Cardioverter-Defibrillators (ICD) are highly effective in diagnosing and treating life threatening arrhythmias, inappropriate shock therapy (IST) occurs in approximately 5-20% of ICD recipients. IST results in pain, anxiety, induction of ventricular arrhythmias, decreased battery longevity, and even death. Researchers studying clinical predictors of IST have drawn findings based on single case studies with small samples or with outdated data. This study filled this gap by describing the incidence and co-existing clinical predictors of IST. Methodology This descriptive, retrospective study analyzed the incidence and clinical predictors of IST …

Approaches To Improve The Ovulatory Response And Reproductive Performance Of Ewes Introduced To Rams During Seasonal Anestrus, Katherine Mead Jordan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Three experiments were conducted to test hypotheses relative to the ability of gonadotropin releasing hormone (GnRH) and melatonin to improve responses of anestrous ewes to rams. Treatment with GnRH two days after treatment with progesterone at introduction of rams did not increase ovulation, pregnancy or lambing rates. Treatment with GnRH on days two, seven, or both after introduction of rams, resulted in ovulation, pregnancy, and lambing rates that did not differ. In another trial, GnRH four days before, or four days before and one day after introduction of rams did not improve a consistently high ovulatory response to introduction of …

Immune-Endocrine Interactions In The Lizard Sceloporus Undulatus Hyacinthinus: Testing An Assumption Of The Immunocompetence Handicap Hypothesis, Mukta Chakraborty

All-Inclusive List of Electronic Theses and Dissertations

The immunocompetence handicap hypothesis (IHH) was proposed by Folstad and Karter ( 1992) to describe the role of the endocrine system in ensuring honesty of sexual signaling. Numerous studies have investigated the assumptions of the IHH, but currently there is mixed evidential support in favor of the IHH. The first chapter of this thesis is a review examinining these studies, their limitations, and proposed alternative models and future directions. The second chapter of this thesis presents a study in which we experimentally assesss the testosterone immunosuppression assumption in adult male Sceloporus undulatus lizards. We manipulated circulating androgen levels (Day 0) …

Re-Presenting The Religious: Nation, Community And Identity In Museums, Lily Kong

Research Collection School of Social Sciences

This paper examines the roles that museums play as 'unofficially sacred' places, underscoring or challenging the religious life of a people and 'nation'. It focuses on three key questions: (1) Do sub-national and transnational religious formations pose a challenge to or present opportunities for nation-building strategies, and what part do museums play in this struggle? (2) In what ways do re-presentations of religion in museums contest or reinforce religious community and identity? and (3) What challenges do museum displays pose to the understanding of religious meanings? This paper explores these three key questions about the intersection of religion with politics …

Why The Federal Marriage Amendment Is Necessary, Christopher Wolfe

San Diego Law Review

The Federal Marriage Amendment seeks to confine marriage to one man and one woman. This article supports the Federal Marriage Amendment because the Amendment reinforces the original design of the Constitution in the face of unchecked judicial review power and the expansion of sexual autonomy. The Federal Marriage Amendment reinforces the idea that the people of the states, not the judiciary, resolve social policy. Also, the Amendment supports a presumption in favor of state legislation on marriage. Although conservatives, such as Yoo and Vulchev, state that the Federal Marriage Amendment opposes federalism, this author contends that the Amendment would preserve …

Why The Federal Marriage Amendment Is Not Only Not Necessary, But A Bad Idea: A Response To Christopher Wolfe, Michael Perry

San Diego Law Review

The Federal Marriage Amendment does more than prevent same-sex couples from having marital status. In response to Professor Wolfe, this article contends that the Federal Marriage Amendment prevents state courts and state legislatures from choosing to grant marital status to same-sex couples. Gender complimentarity, the heart of Professor Wolfe's argument and the Federal Marriage Amendment's basis, is too controversial and problematic to bind future generations from allowing same-sex marriage. Even if society is currently opposed to same-sex marriage, this author concludes that the U.S. Constitution should not be amended in a way that prevents future generations from deciding whether to …

Liberals And Libertines: The Marriage Question In The Liberal Political Imagination, Nomi Maya Stolzenberg

San Diego Law Review

Liberalism and marriage are not easily separated from anti-libertine and libertine ideas. This article frames the meaning of marriage question by comparing Tolstoy’s anti-libertine novella, The Kreutzer Sonata with Roth?s libertine novella, The Dying Animal. Both novellas impale marriage and liberalism to reveal the strains of ambivalence toward freedom of love, sex, and personal attachments. In Tolstoy’s novella, Pozdnyshev reviles marriage because it is nothing more than licensed prostitution. In Roth’s novella, Kepesh despises marriage because it dampens sex and subjects the individual to constraints. The author offers two readings of these novellas, one that emphasizes the boundaries between liberal, …

Organizational Evolution: Applying Genetic Principles To The Management Of Extension Systems, John A. Winder

Journal of Extension

Insight into organizational management can be gained by looking at natural systems. Ideas in Extension organizations are analogous to the genetic makeup of populations of organisms. Genetic makeup determines the chemistry, size and behavior of these populations. Similarly, ideas in organizations determine the future size, activities and effectiveness. This article first examines the principles of population genetics and how these principles drive genetic change. This concept is then extended to Extension to demonstrate how ideas appear to follow similar laws. Finally, this concept is used to derive suggestions for improving effectiveness of organizations.

Barriers To Change: Farmers' Willingness To Adopt Sustainable Manure Management Practices, Robert D. Battel, David E. Krueger

Journal of Extension

Manure management is important in Michigan. There is need for better understanding of why farmers do not sustainably utilize manure nutrients. Some livestock farms could benefit if neighboring farmers used their manure. A study explored the potential for manure transfer from livestock farms to fields of neighboring farms. A mailed survey was used to collect data. Surveys were analyzed to determine frequencies of responses among respondents. Comparisons were also made between livestock and nonlivestock farmers. Results suggest neighbor complaints and odor represent significant barriers to manure exchange. Concerns about spreading weed seeds and economic issues are also significant barriers.

Use Of A Cattle Feeding Profitability Prediction Contest In Beef Extension Programming, Jane A. Parish, W Blair Mckinley

Journal of Extension

A beef cattle feeding profitability predication contest was established in conjunction with the Mississippi Farm to Feedlot Project, an 11-year-old program similar to many cattle feeding Extension programs offered across the nation. This contest was initiated to demonstrate the value of knowing the genetic and profit potential of calves prior to deciding to feed these animals or market them at weaning or after stocker grazing. It also stimulated renewed interest in the Mississippi Farm to Feedlot Project and expanded the audience reached by this educational effort. Results of this contest indicate that it was successful in achieving its objectives.

Wonderwise 4-H: Following In The Footsteps Of Women Scientists, Amy N. Spiegel, S Kay Rockwell, Deanna Acklie, Saundra Wever Frerichs

Journal of Extension

Wonderwise 4-H: Women in Science Learning Kits, recently included in the National 4-H Curriculum Collection and widely tested by 4-H leaders, have positively affected youths' perspectives on science, scientists, and scientific work. Adult leaders who used the multi-media, inquiry-based Wonderwise 4-H kits completed a Web survey describing the impact of the kits on youth. It indicated that the kits increased youth's interest and understanding of science, broadened their view of scientists, and opened their eyes to the possibility of science in their own futures. More information about Wonderwise 4-H and downloadable activities are available at .

Manure Use Planning: An Evaluation Of A Producer Training Program, Charles S. Wortmann, Richard K. Koelsch, Charles A. Shapiro, Richard L. Deloughery

Journal of Extension

A training program for producers in manure use planning was evaluated. The potential for runoff nutrient loss to surface water can reduced and the value of manure increased through better planning of manure use. Training was conducted throughout Nebraska in 2002 and 2003. Livestock producers who attended evaluated the event at the end of the last class. The need for and impact of the training was greater for continuing operational and maintenance skills of manure utilization that are regularly needed for strategic planning skills. We recommend that training focus primarily on operational and maintenance skills.

Demonstrating Manure Spreader Calibration At Field Days, Karen M. Mancl, J Dean Slates

Journal of Extension

Calibration of a manure spreader was demonstrated at field days. Data collected showed limited capability of farmers to estimate manure application rates just based on their experience and the importance of calibration. Only 13% estimated at or near the actual application rate (±1 ton). Some (22%) estimated high rates, with two estimating four times the actual application rate. Most (65%) underestimated the rate, with 50% estimating less than one-half the actual application rate. The tendency to underestimate manure application and therefore over-apply manure reinforces the need to calibrate spreading equipment as a part of a manure management plan.

Regulatable Gene Expression Systems For Gene Therapy Applications: Progress And Future Challenges, Shyam Goverdhana, Mariana Puntel, Weidong Xiong, Jeffrey Zirger, Carlos Barcia, James Curtin, Eric Soffer, Sonali Mondkar, Gwendalyn King, Jinwei Hu, Marianela Candolfi, Diane Greengold, Pedro Lowenstein, Maria Castro

Articles

Gene therapy aims to revert diseased phenotypes by the use of both viral and nonviral gene delivery systems. Substantial progress has been made in making gene transfer vehicles more efficient, less toxic, and nonimmunogenic and in allowing long-term transgene expression. One of the key issues in successfully implementing gene therapies in the clinical setting is to be able to regulate gene expression very tightly and consistently as and when it is needed. The regulation ought to be achievable using a compound that should be nontoxic, be able to penetrate into the desired target tissue or organ, and have a half-life …

Second Graders' Favorite Weather Drawings, Ashley L. Sherman

EVMS School of Health Professions Theses & Dissertations

The Favorite Weather Drawing has been used extensively as an art therapy assessment tool. It has been theorized to contain certain variables that relate to a child’s underlying mood or perception of his or her environment. Since neither the Favorite Weather Drawing nor the similar Favorite Kind of Day Drawing have been researched extensively or standardized with normative populations, there has been a lack of research that could provide a much-needed foundation for such a popular assessment technique. This study explored regional and gender differences in the Favorite Weather Drawing of 2nd grade students as a way to provide groundwork …

Characteristics Of Bipolar Disorder In Adult Favorite Weather Drawings, Carrie L. Elder

EVMS School of Health Professions Theses & Dissertations

The purpose of this study was to identify graphic indicators of Bipolar Disorder in Favorite Weather Drawings. The subjects in this study consisted of 9 individuals diagnosed with a Bipolar Disorder and 16 individuals without a Bipolar Disorder diagnosis. The age range was 22 to 64 years. It was hypothesized that Favorite Weather Drawings rendered by individuals diagnosed with Bipolar Disorder would differ in color, expansiveness, line quality, and weather themes from Favorite Weather Drawings rendered by individuals without a diagnosis of Bipolar Disorder. These differences were measured using a Favorite Weather Drawing Checklist and analyzed for resulting patterns.

Archaeology, Relics, And Book Of Mormon Belief, John E. Clark

Journal of Book of Mormon Studies

Archaeology has much to offer as a scientific means of gathering independent evidence of the Book of Mormon’s authenticity. But one must look in the right place. A cautionary tale is the failed Cluff expedition of 1900, which, assuming a “hemispheric model” of Book of Mormon geography, traveled from Provo as far as Colombia looking for the city Zarahemla. Yet in 1842 the Times and Seasons (under Joseph Smith’s editorship) had printed excerpts from a popular book on Mesoamerican archaeology that demonstrated a surprisingly high level of civilization, implying that Nephite lands did not extend into South America, thus supporting …

A Role For Mitogen-Activated Protein Kinase (Erk1/2) Activation And Non-Selective Pore Formation In P2x7 Receptor-Mediated Thymocyte Death, Rodolphe Auger, Iris Motta, Karim Benihoud, David M. Ojcius, Jean M. Kanellopoulos

All Dugoni School of Dentistry Faculty Articles

Extracellular ATP (ATPe) binds to P2X7 receptors (P2X7R) expressed on the surface of cells of hematopoietic lineage, including murine thymocytes. Activation of P2X7R by ATPe results in the opening of cation-specific channels, and prolonged ATPe exposure leads to the formation of non-selective pores enabling transmembrane passage of solutes up to 900 Da. In the presence of ATPe, P2X7R-mediated thymocyte death is due primarily to necrosis/lysis and not apoptosis, as measured by the release of lactate dehydrogenase indicative of a loss of plasma membrane integrity. The present study is focused on the identification of P2X7R signaling mediators in ATP-induced thymocyte necrosis/lysis. …

A Comprehensive Ecological Land Classification For Utah's West Desert, Neil E. West, Frank L. Dougher, Gerald S. Manis, R. Douglas Ramsey

Wildland Resources Faculty Publications

Land managers and scientists need context in which to interpolate between or extrapolate beyond discrete field points in space and time. Ecological classification of land (ECL) is one way by which these relationships can be made. Until regional issues emerged and calls were made for ecosystem management (EM), each land management institution chose its own ECLs. The need for economic efficiency and the increasing availability of geographic information systems (GIS) compel the creation of a national ECL so that communication across ownership boundaries can occur. ECOMAP, an 8-level, top-down, nested, hierarchical, multivariable approach designed to solve this problem has been …

Combined Interviews

Mr. Del Real describes how he initially heard of the Bracero Program through word of mouth; in 1952, when he began the enrollment process, he was already married and had children; he went through contracting centers in Chihuahua, Chihuahua, México, and Empalme, Sonora; there were huge crowds of people at these centers, which proved to be problematic due to the long waiting periods; he explains the procedures he underwent, including the medical exams and the delousing process; furthermore, he describes the delousing procedures as discriminatory; as a bracero, he was able to obtain eight working contracts, which took him to …

Evaluating Lek Occupancy Of Greater Sage-Grouse In Relation To Landscape Cultivation In The Dakotas, Joe T. Smith, Lester D. Flake, Kenneth F. Higgins, Gerald D. Kobriger, Collin G. Homer

Western North American Naturalist

Greater Sage-Grouse (Centrocercus urophasianus) have been declining in many states and provinces of North America, and North and South Dakota hold no exception to these declines. We studied effects of cultivated land on Greater Sage-Grouse lek abandonment in North and South Dakota. Landscape-level data were assessed using satellite imagery within a geographic information system. Comparisons were made of 1972–1976 and 1999–2000 percent cultivated and noncultivated land. These comparisons were made between land uses surrounding active leks versus inactive leks, active leks versus random locations, and abandoned regions versus active regions. The 1999–2000 imagery illustrated that percent cultivated land …
