The materials were tested for mechanical properties including tensile and flexure strengths. The highest tensile …

What Hath Faith Wrought? (Book Review), Michael S. Ariens

Faculty Articles

A number of academic lawyers have explored the relationship of religion (and religious belief) and law. Ostensibly starting with the late Harold Berman’s The Interaction of Law and Religion, the “religious lawyering” movement evaluates the role religious faith has in how lawyers practice law. Extended by subsequent works such as Christian Perspectives on Legal Thought, the discussion has expanded beyond the question whether a religious lawyer is a contradiction.

This essay serves as a commentary on Robert F. Cochran’s Faith and Law: How Religious Traditions from Calvinism to Islam View American Law, a compilation of sixteen essays from legal academics …

Data Security And Tort Liability, Vincent R. Johnson

Faculty Articles

Established tort principles carefully applied to the contemporary problems of cybersecurity and identity theft can perform a key role in protecting the economic foundations of modern life. Tort law offers an appropriate legal regime for allocating the risks and spreading the costs of database intrusion-related losses. It can also create incentives, on the part of both database possessors and data subjects, to minimize the harm associated with breaches of database security.

In considering this field of tort law, it is useful to differentiate three questions. The first issue is whether database possessors have a legal duty to safeguard data subjects’ …

Loose Lips Sink Attorney-Client Ships: Unintended Technological Disclosure Of Confidential Communications, Bill Piatt, Paula Dewitte

Faculty Articles

Attorneys have an ethical obligation to protect their clients' confidences. Attorneys are required to consider what possibilities exist for unintended disclosure through technology, how they can adapt to these new realities to fulfill obligations of effective representation and maintenance of client trust and confidences, and how attorneys can employ a tripartite approach to information security to better protect client information. Under the general obligation to maintain confidentiality as set out in Rule 1.6 of the Model Rules of Professional Conduct, attorneys are precluded from revealing “information relating to the representation of a client.”

The legal profession has started to educate …

Locavore Exploring The Sustainable Table: A Restaurant In Tobacco Row, Kathryn Mia Oliver

Theses and Dissertations

Locavore is a restaurant centered around the principles of sustainable agriculture: foodthat is organically, humanely, and sustainably raised from farms and cooperatives nofurther than 150 miles from Richmond - thus the "local" in Locavore. Like all restaurants,certain programmatic requirements were standard such as providing places to store,prepare, and eat the food, and restrooms. Yet the design of the space also helps answerthe following questions: How does sustainable differ from organic? Is local necessarily better than foreign? How does a restaurant embody community?

Grace Street Senior Center, Virginia Brockett

Theses and Dissertations

Societal structure has changed through the decades to reflect a contemporary interest in youth culture. The nuclear family, where generations lived under one roof no longer exists, leaving the elderly on the periphery of the family structure. Where once grandparents, parents and children all cohabitated, now the oldest family members are relegated to solitary retirement and aging alone. Studies have shown that "depression in the elderly is more likely to lead to suicide. Elderlywhite men are at greatest risk, with suicide rates in people ages 80 to 84 more than twice that of the general population. The National Institute of …

Examination Of Preferred Coaching Behaviors As Predicted By Athlete Gender, Race, And Playing Time, Glenn Parrish Burdette

College of Graduate Studies: Theses & Dissertations

The Multidimensional Model for Sport Leadership (MML) (Chelladurai, 1980) states that athlete performance and satisfaction are functions of the congruency between the preferred leadership of student-athletes, the required behavior of the coach as dictated by the situation, and the actual behavior of the coach. The model was developed nearly 30 years ago and while research outside of sport has indicated that leadership preferences have changed with generations, the MML is still the most widely accepted model for sport leadership. As such, research in sport should examine how appropriate the model is to todays athletic culture. Gender, one member characteristic, has …

Assessment Of Costs Associated With Deer–Vehicle Collisions: Human Death And Injury, Vehicle Damage, And Deer Loss, John A. Bissonette, Christine A. Kassar, Lawrence J. Cook

Human–Wildlife Interactions

Collisions between large vertebrates and vehicles along roadways are an increasing concern, not only because of ecological consequences, but also because of associated economic and social costs. We used a large-scale, long-term data set comprising several databases from Utah to summarize and analyze these costs. The overall cost for 13,020 collisions from 1996 to 2001 in Utah was approximately $45,175,454, resulting in an estimated average per year cost of about $7,529,242 and a mean collision cost of $3,470. These figures include human fatality costs of $24 million (53% of total costs); vehicle damage costs of $18 million (39%); loss of …

Landscape And Traffic Factors Influencing Deer–Vehicle Collisions In An Urban Enviroment, Janet W. Ng, Charlene Nielsen, Colleen Cassady St. Clair

Human–Wildlife Interactions

Deer–vehicle collisions (DVCs) are steadily increasing across North America. The increase is particularly pronounced in urban green spaces where deer (Odocoileus spp.) populations and road densities are high. In the greater city of Edmonton, Alberta, Canada, 333 DVCs occurred from 2002 to 2004. To identify landscape and traffic correlates of these collisions, we built 3 statistical models. The first model assessed the importance of local variables and was based on a spatial precision of the nearest intersection to which collisions were referenced. The second model was based on landscape characteristics and used the nearest township intersection to aggregate collisions. …

Sharpshooting Suburban White-Tailed Deer Reduces Deer–Vehicle Collisions, Anthony J. Denicola, Scott C. Williams

Human–Wildlife Interactions

Too many deer–vehicle collisions (DVCs) are one of the primary reasons local governments implement lethal deer management programs. However, there are limited data to demonstrate that a reduction in deer (Odocoileus spp.) densities will result in a decline in DVCs. We conducted sharpshooting programs in 3 suburban communities to reduce deer numbers and to address rising DVCs. Annual or periodic population estimates were conducted using both helicopter snow counts and aerial infrared counts to assess population trends. Management efforts were conducted from 3 to 7 years. Local deer herds were reduced by 54%, 72%, and 76%, with resulting reductions …

Human–Wildlife Interactions

White-tailed deer (Odocoileus virginianus) mortalities (n = 4,433) caused by collisions with automobiles during 2003 were modeled in 35 counties in eastern South Dakota. Seventeen independent variables and 5 independent variable interactions were evaluated to explain deer mortalities. A negative binomial regression model (Ln Y = 1.25 – 0.12 [percentage tree coverage] + 0.0002 [county area] + 5.39 [county hunter success rate] + 0.0023 [vehicle proxy 96–104 km/hr roads], model deviance = 33.43, χ2 = 27.53, df = 27) was chosen using a combination of a priori model selection and AICc. Management options include use of the model …

Physiological Effects Of Gonadotropin-Releasing Hormone Immunocontraception On White-Tailed Deer, Paul D. Curtis, Milo E. Richmond, Lowell A. Miller, Fred W. Quimby

Human–Wildlife Interactions

Before immunocontraceptives can be considered safe to use on wildlife species, potential health risks should be assessed. Gonadotropin-releasing hormone (GnRH) immunocontraceptive has successfully reduced fertility of white-tailed deer (Odocoileus virginianus); however, associated deer physiology has rarely been examined. We conducted gross necropsy examinations, histology, and blood chemistry comparisons on euthanized deer previously vaccinated with immunogenic GnRH (n = 18 females and n = 4 males), or left as untreated controls (n = 7 females and n = 6 males). Granulomas were found at injection sites of most deer, even 3 years post-treatment. There were no significant …

Gnrh Immunocontraception Of Male And Female White-Tailed Deer Fawns, Lowell A. Miller, James P. Gionfriddo, Jack C. Rhyan, Kathleen A. Fagerstone, Donald C. Wagner, Gary J. Killian

Human–Wildlife Interactions

Immunocontraceptive vaccines based on gonadotropin-releasing hormone (GnRH) have been tested in adult white-tailed deer (Odocoileus virginianus), but their effects on fawns are unknown. The purpose of this study was to determine if early immunization against GnRH would induce a long-lasting immune response in fawns, and if it would delay or prevent sexual development. We gave primary and subsequent booster injections of a KLH-GnRH/Freund’s vaccine to 6 male and 6 female fawns. This vaccine contained the same active ingredients as GonaCon™ vaccine, but it contained Freund’s adjuvant instead of AdjuVac™ adjuvant. Two 450-μg injections were given 1 month apart …
