Who's Afraid Of The Precautionary Principle?, Robert V. Percival

Faculty Scholarship

The precautionary principle – the notion that lack of scientific certainty should not foreclose precautionary regulation – has become enormously popular in recent years, as reflected by its endorsement in many important international declarations and agreements. Despite its growing influence, the precautionary principle recently has come under fire by critics who argue that it is incoherent, potentially paralyzing, and that it will lead regulators to make bad choices. They maintain that society faces greater peril from overly costly regulations than from exposure to sources of environmental risks whose effect on human health and the environment is not fully understood at …

Virtual Worlds As Comparative Law, James Grimmelmann

Faculty Scholarship

What would happen if we took seriously the claims of virtual worlds to be genuinely new places? Societies have laws, so why should virtual societies be any different? My topic, then, will not be the law of virtual worlds, but rather law in virtual worlds. If lawyers can learn from studying the legal systems of common law and civil law countries, perhaps we can also learn from studying the legal systems of virtual worlds.

In some cases, these legal systems track our own surprisingly well. In other cases, the contrasts are striking. Both the similarities and differences between real-life law …

Ethical Leadership In The U.S.: How Can Business Schools Help To Build And Maintain An Atmosphere Of Trust In Business Leadership?, Christine M. Barber

Seminar Research Paper Series

Corporate scandals have rocked the foundations of many corporations in America. Those affected directly and indirectly, as well as those who do not want to be the next front page headline. This paper looks at the fact that there is a problem. How did it get this way and what can be done to turn the situation around? Congress reacted with the Sarbanes-Oxley Act and additions to the Federal Sentencing Guidelines for Organizations. Corporations are developing codes of ethics and ethical training programs like never before to try to head off potential liabilities. Business schools that once felt ethics training …

The Transcriptome Of The Salivary Glands Of The Female Western Black-Legged Tick Ixodes Pacificus (Acari: Ixodidae), Ivo M.B. Francischetti, Van My Pham, Ben J. Mans, John F. Andersen, Thomas N. Mather, Robert S. Lane, José M.C. Ribeiro

Plant Sciences and Entomology Faculty Publications

Sequencing of an Ixodes pacificus salivary gland cDNA library yielded 1068 sequences with an average undetermined nucleotide of 1.9% and an average length of 487 base pairs. Assembly of the expressed sequence tags yielded 557 contigs, 138 of which appear to code for secreted peptides or proteins based on translation of a putative signal peptide. Based on the BLASTX similarity of these contigs to 66 matches of Ixodes scapularis peptide sequences, only 58% sequence identity was found, indicating a rapid divergence of salivary proteins as observed previously for mosquito and triatomine bug salivary proteins. Here we report 106 mostly full-length …

Prenatal Stress And Stress Physiology Influences Human Fetal And Infant Development, Elyssia Poggi Davis, Calvin J. Hobel, Curt A. Sandman, Laura M. Glynn, Pathik D. Wadhwa

Psychology Faculty Books and Book Chapters

"Prenatal stress has been proposed as a risk factor that may have developmental consequences persisting throughout the lifespan. Exposing rodents to stress during pregnancy has consequences for brain development, stress regulation, learning, emotionality (increased anxiety), and social behavior (increased withdrawal) of the offspring (Weinstock, 2001; Chapillon et al., 2002). Additionally, non-human primates who experience stress during pregnancy have offspring with enhanced behavioral reactivity to stressors later in life (Clarke et al., 1994), lowered levels of motor behavior (Schneider, 1992), compromised neuromotor responses (Schneider and Coe, 1993), irritable temperament (Schneider et al., 1992), and attentional problems (Schneider et …

Gamers’ Sensations Of Spatial, Social, And Co-Presence While Playing Online Video Games, Cheryl Campanella Bracken, R. L. Lange, James Denny

Communication Faculty Publications

There is an increasing number of video gamers who are playing games online. Previous research has demonstrated that off line gamers experience sensations of presence “the illusion of non-mediation” (Lombard & Ditton, 1997). The current study, explores through focus groups, the type of presence online gamers report experiencing. The results demonstrate that online gamers report having sensations that can be classified into all three main presence types: spatial (physical), social, and co-presence.

Diversity Of The Unionidae In The Rocky River, Ohio, Robert A. Krebs, Louie J. Rundo

Biological, Geological, and Environmental Faculty Publications

We surveyed the freshwater mussels (Mollusca: Bivalvia: Unionidae) of the Rocky River, Ohio, USA, a river surrounded by suburban development. The survey produced 253 live unionid specimens and 572 empty shells. Most occurred in the west branch. Species living in the West Branch Rocky River included Anodontoides ferussacianus, Elliptio dilatata, Lampsilis cardium, Lampsilis radiata luteola, Lasmigona compressa, Lasmigona costata, Pyganodon grandis grandis, Strophitus undulatus undulatus, and Toxolasma parvus. Two additional species (Utterbackia imbecillis and Villosa iris iris) were represented as dead shells. Three species (Potamilis alatus, Quadrula quadrula and Leptodea fragilis) were found only near the …

Co-Operative Marketing Structures In Rural Tourism: The Irish Case, Catherine Gorman

Books / Book chapters

It is recognised that co-operative practises amongst tourism providers creates competitive advantage through utilising and sharing resources. This leads to efficiencies and more effective provision of a valued experience for the visitor. This chapter explores the co-operative practises being utilised by three groups operating within the rural tourism sector in Ireland. It identifies barriers to co-operation and summates that frequent communication and evident benefits are key considerations in implementing an effective co-operative approach.

Risking It All, Lisa Heinzerling

Georgetown Law Faculty Lectures and Appearances

Thank you for inviting me here today. I feel privileged to deliver this lecture honoring Daniel Meador, a beloved alumnus, former Dean, and colleague.

I congratulate the organizers of this year's three-part lecture series for choosing the topic "Risk and the Law." The topic is timely, full of rich possibilities for analysis, and as contentious as any matter in legal academics today. If you attend all of the lectures - mine, plus those by Professors Simon and Sunstein - I believe you will begin to see why issues of risk are so important and so hard, and I am certain …

Inducible Ablation Of Mouse Langerhans Cells Diminishes But Fails To Abrogate Contact Hypersensitivity, Clare L. Bennett, Erwin Van Rijn, Steffen Jung

Publications

Langerhans cells (LC) form a unique subset of dendritic cells (DC) in the epidermis but so far their in vivo functions in skin immunity and tolerance could not be determined, in particular in relation to dermal DC (dDC). Here, we exploit a novel diphtheria toxin (DT) receptor (DTR)/DT-based system to achieve inducible ablation of LC without affecting the skin environment. Within 24 h after intra-peritoneal injection of DT into Langerin-DTR mice LC are completely depleted from the epidermis and only begin to return 4 wk later. LC deletion occurs by apoptosis in the absence of inflammation and, in particular, the …

Network Of Dendritic Cells Within The Muscular Layer Of The Mouse Intestine, Adriana Flores-Langarica, Selene Meza-Pérez, Juana Calderón-Amador

Publications

Dendritic cells (DCs) are located at body surfaces such as the skin, respiratory and genital tracts, and intestine. To further analyze intestinal DCs, we adapted an epidermal sheet separation technique and obtained two intestinal layers, facing the lumen and serosa. Unexpectedly, immunolabeling of the layer toward the serosa revealed a regular, dense, planar network of cells with prominent dendritic morphology within the external muscular layer and with increasing frequency along the length of the intestine. Direct examination of the serosal-disposed layers showed a significant fraction of the DCs to express DEC-205/CD205, CD11c, Langerin/CD207, Fcγ receptor/CD16/32, CD14, and low levels of …

Innate Nkt Lymphocytes Confer Superior Adaptive Immunity Via Tumor-Capturing Dendritic Cells, Kang Z. Liu, Juliana Idoyaga, Anna Charalambous

Publications

If irradiated tumor cells could be rendered immunogenic, they would provide a safe, broad, and patient-specific array of antigens for immunotherapies. Prior approaches have emphasized genetic transduction of live tumor cells to express cytokines, costimulators, and surrogate foreign antigens. We asked if immunity could be achieved by delivering irradiated, major histocompatibility complex-negative plasmacytoma cells to maturing mouse dendritic cells (DCs) within lymphoid organs. Tumor cells injected intravenously (i.v.) were captured by splenic DCs, whereas subcutaneous (s.c.) injection led only to weak uptake in lymph node or spleen. The natural killer T (NKT) cells mobilizing glycolipid α-galactosyl ceramide, used to mature …

Density And Cover Preferences Of Black-And-Rufous Elephant-Shrews (Rhynchocyon Petersi) In Chome Forest Reserve, Tanzania, Stephanie Coster, David O. Ribble

Biology Faculty Research

The objective of this study was to determine the density and habitat preference of the Black-andrufous elephant-shrew (Rhynchocyon petersi) in Chome Forest Reserve, Tanzania. Chome Forest (143km²) is located in the South Pare Mountains and provides critical habitat for endangered R. petersi. Twelve 300m transects were cut through the centre of the forest in an east-west direction and the number of elephant-shrew nests within 2.5 meters on each side of the transects was recorded. The mean number of nests per 100m transect (0.39 ± 0.47 [1SE]) translated to a density estimate of 19 elephant-shrews per …

A Two-Year Seasonal Analysis Of Wetland Vegetation At The Mcclintic Wildlife Management Area In Mason County, West Virginia, Anne Carrington Blankenship

Theses, Dissertations and Capstones

Disturbances play a key role in the structure of ecosystems. Most ecosystems are subject to several different disturbance regimes that occur at different temporal and spatial scales. Studying the effects of disturbances can lead to a better understanding of a vegetative community’s future productivity. However, in order to understand the effects of disturbance, a vegetative community should first be studied before the disturbance occurs. This study analyzes the composition and seasonal variations of vegetative communities in and around four ponds at the McClintic Wildlife Management Area in Mason County, West Virginia during two growing seasons prior to remediation activities in …

Home Range And Behavior Of The Timber Rattlesnake (Crotalus Horridus), Jennifer P. Adams

Theses, Dissertations and Capstones

Seventeen timber rattlesnakes were surgically implanted with radio transmitters and subsequently radio-tracked to determine the home range and behavior, as well as cause-specific mortality, of timber rattlesnakes on production forests in Randolph County, West Virginia. Mean home range sizes were 94.3 ha, males; 31.2 ha, nongravid females; 8.5 ha, gravid females; and 44.7 ha, among sex classes. Among sex classes, the mean daily movement rate was 20.2 mper day; the mean maximum known distances from den sites was 1110.2 m; the mean distance from den sites was 514.2 m; and the mean total distance moved was 2852.9 m. Mean active …

Warriors Of The Skyline : A Gendered Study Of Mohawk Warrior Culture, Anthony Patrick Curtis

Theses, Dissertations and Capstones

This analysis provides a better understanding of how members of the Mohawk tribe strived to maintain their cultural and gender identity within a white male-dominated high steel industry. This thesis examines traditional Mohawk warrior culture, meaning traditional Mohawk rites of passage and Mohawk male gender roles, through analyzing the role of Mohawk skywalkers in the late 19th and early 20th century. In tribal Mohawk society, the passage from adolescence to manhood was representative of a boy becoming a warrior. By exhibiting bravery, he earned the title of warrior and, consistent with his new tribal stature, increased his chances at marriage …

Effects Of Aging On Pressure-Induced Mapk Activation In The Rat Aorta, Kevin M. Rice

Theses, Dissertations and Capstones

With age, the cardiovascular system experiences substantial alterations in cellular morphology and function. The factors regulating these changes are unknown; however, the mitogen activated protein kinase (MAPK) pathways have emerged as critical components for mediating numerous cellular responses including control of cell growth, differentiation and adaptation. Here we compare the expression, basal activation and the ability of increased pressure to activate the MAPK pathways in adult (6 month old), aged (30 month old) and very aged (36 month old) Fischer 344 x Brown Norway F1 Hybrid rats. Histochemical analysis demonstrated an age-related increase in tunica media thickness of approximately 11% …

Habitat Analysis By Hierarchical Scheme And Stream Geomorphology, James B. Spence

Theses, Dissertations and Capstones

A study was undertaken to classify eight stream reaches in the North Branch of the Potomac River watershed and determine if geomorphologic differences influenced the availability of fish habitat structure and fish density. Stream reaches were classified using Rosgen Level II (1996) methods, and fish habitat was determined using Hydraulic Channel Unit (HCU) classification based on a method modified from Bisson et al. (1982). Other habitat variables were also studied such as stream shading and physical habitat based on the Rapid Bioassessment Protocol (Barbour et al. 1999). Despite the differences in HCU density between sites, HCU density did not influence …

Comparisons Of Morphology And Reproductive Status Of Plethodon Glutinosus At High, Middle, And Low Elevations In West Virginia, Cynthia F. Lucas

Theses, Dissertations and Capstones

Plethodon glutinosus populations in West Virginia were looked at in three different elevations. Objectives were to determine if there is enough difference in elevation to cause different populations to vary in morphology and reproduction. Nine morphological measurements were taken to represent both size and proportional shape. Sexual dimorphism was found in all measurements only in low elevations, males being larger (p<0.001-p=0.041). Mean measurements between the three elevations showed significant differences (p<0.005) in all measurements excluding head width, tail length, and 3rd digit length. Salamanders were dissected; testes and vasa deferentia were removed from males and ovaries with follicles were removed from females. Results showed males in lower and middle elevations deposit spermatophores May-July. Low sample sizes in higher elevations provided inconclusive results. Females of lower elevations lay eggs early-mid summer. Middle and higher elevations results revealed a likely spring oviposition, or possibly a fall oviposition.
