Heteronormativity In Employment Discrimination Law, Naomi Schoenbaum

GW Law Faculty Publications & Other Works

This symposium Essay responds to the EEOC’s new decision to interpret federal employment discrimination law’s ban on discrimination on the basis of sex to include a ban on discrimination on the basis of sexual orientation. It argues that although the EEOC’s decision does provide cause to celebrate, ongoing heteronormativity in federal employment discrimination law will continue to stand as a barrier to equal employment opportunity for gay workers. First, Title VII provides an exception to the sex discrimination ban in the context of intimate spaces, allowing, for example, only women to be hired to serve as labor and delivery nurses. …

What’S Right About Knowing?, Naomi R. Cahn

GW Law Faculty Publications & Other Works

In Sperm donor anonymity and compensation: an experiment with American sperm donors, the authors contribute to our knowledge about the impact of moving toward a system of known sperm donation in the USA by surveying a population of active and inactive actual sperm donors. Their conclusions—slightly more than a quarter would refuse to contribute, while the remaining donors would require an additional $60 per donation—are interesting and useful in modeling the implications of moving towards a new regime that allows for limited disclosure.

Yet this study must be placed in a larger context that considers not just the market for …

How Adverse Outcome Pathways Can Aid The Development And Use Of Computational Prediction Models For Regulatory Toxicology, Clemens Wittwehr, Hristo Aladjov, Gerald Ankley, Hugh Byrne, Joop Deknecht

Articles

Efforts are underway to transform regulatory toxicology and chemical safety assessment from a largely empirical science based on direct observation of apical toxicity outcomes in whole organism toxicity tests to a predictive one in which outcomes and risk are inferred from accumulated mechanistic understanding. The adverse outcome pathway (AOP) framework provides a systematic approach for organizing knowledge that may support such inference. Likewise, computational models of biological systems at various scales provide another means and platform to integrate current biological understanding to facilitate inference and extrapolation. We argue that the systematic organization of knowledge into AOP frameworks can inform and …

Contaminant levels in fish were generally low with PCBs in fish liver below OSPAR environmental assessment criteria (EAC). There were …

An Enhanced Spring-Particle Model For Red Blood Cell Structural Mechanics: Application To The Stomatocyte–Discocyte– Echinocyte Transformation, Mingzhu Chen, Fergal Boyle

Articles

Red blood cells (RBCs) are the most abundant cellular element suspended in blood. Together with the usual biconcave-shaped RBCs, i.e., discocytes, unusual-shaped RBCs are also observed under physiological and experimental conditions, e.g., stomatocytes and echinocytes. Stomatocytes and echinocytes are formed from discocytes and in addition can revert back to being discocytes; this shape change is known as the stomatocyte–discocyte–echinocyte (SDE) transformation. To-date, limited research has been conducted on the numerical prediction of the full SDE transformation. Spring- particle RBC (SP-RBC) models are commonly used to numerically predict RBC mechanics and rheology. However, these models are incapable of predicting the full …

Construction Of Bacterial Strains Containing A Plasmid Producing An Opossum-Based Anti-Venom Peptide For Low Cost Production Of The Peptide, Angela Cifelli

Master's Theses

A cost-effective therapy for snake bites and other biological toxins could save thousands of lives each year. A low-cost therapy can be achieved using a bacterial host that expresses a peptide that prevents death when administered after exposure to these toxins. A protein expressed in opossums, lethal toxin neutralizing factor (LTNF), provides the animal’s resistance to venom and a variety of other toxins. A small peptide fragment of this protein provides the same lifesaving properties as the full protein sequence. A synthetic copy of this peptide was tested in mice exposed to rattlesnake venom and showed lifesaving potential. The peptide …

A Complete Study Of N,N’ Bis(1 Phenylpropyl) 2,6 Pyridinedicarboxamide, Victoria Y. Chang

Master's Theses

Biological systems are often chiral or involve chiral compounds, e.g. L amino acids, the neurotransmitter L epinephrine. In some cases, two enantiomers of a chiral drug will have different activities, and in extreme cases, one form is therapeutic while the other form is toxic. Therefore, the development of reliable molecular probes for biological applications and chiral sensing is an important area of study. The unique spectroscopic and coordination properties of some lanthanide ions (Ln3+) and their complexes make them suitable for use as molecular probes. Chiral ligand systems have been developed that can coordinate with lanthanide ions to form complexes …

Green Vs. White: An Examination Of Of Media Portrayals Of Radical Environmentalists And White Supremacists, Laurence Pedroni

Master's Theses

The rise of the Trump presidency has highlighted not only the white supremacist history of the U.S., but also reflects danger to the survival of the species in the form of wholesale climate change denial. These ideologies are not unique to Trump or his cabinet, instead reflecting long standing U.S. policy. This research seeks to examine how the U.S. media supports and propagates propaganda to support these hegemonic goals. Relevant literature and research seem to suggest that because radical environmental movements often challenge the hegemony of capital accumulation, they might be portrayed as more violent and a greater terrorist threat …

Evaluation Of Oyster Shell Enhancement On Western Snowy Plover Breeding Success, Karine Tokatlian

Master's Theses

The Pacific Coast population of the western snowy plover (Charadrius nivosus nivosus; plover) is listed as a federally threatened species under the U.S. Endangered Species Act due to poor reproductive success from anthropogenic habitat loss, and high predation pressure. Plovers in the South San Francisco Bay use dry salt evaporation ponds, and wildlife-managed ponds, to breed and winter. However, the South Bay Salt Pond Restoration Project aims to restore up to 6,110 hectares of this habitat back to native tidal marsh, which will force plovers to breed in smaller areas and in higher densities. In order to recover plovers in …

Comparing The Effects Of Mindfulness Meditation And Relaxation In A Brief Laboratory Induction, Carolina A. Caldera

Theses and Dissertations--Psychology

Mindfulness is the practice of being nonjudgmentally aware of the present moment. Researchers often study the effects of mindfulness using brief laboratory-based mindfulness inductions in which participants are guided through mindfulness exercises, after which outcome measures are examined. However, most studies have not assessed whether participants achieved a mindful state during the induction, or whether the effects of mindfulness inductions differ from the effects of similar procedures such as relaxation. The present study compared a mindfulness exercise to a relaxation exercise and a control condition. After the induction, participants completed measures of the extent to which they attained a mindful …

Personality And Learning Predictors Of Adolescent Alcohol Consumption Trajectories, Sarah J. Peterson

Theses and Dissertations--Psychology

In a sample of 1897 youth studied across the last year of elementary school to the second year of high school, we (a) characterized different developmental trajectories of drinking frequency and drinking-related problems and (b) tested an a priori risk model that predicted variation in trajectory group membership. Analyses revealed five separate trajectories for both drinking frequency and drinking problems. Wave 1 scores on impulsigenic traits, expectancies for the reinforcing and stimulating effects of alcohol, and early pubertal onset differentiated among the trajectory groups, in some cases before the groups differed in drinking behavior. We also found substantial covariation between …

Behavioral Deficits Across Development In A Novel Mouse Model Of Fetal Ethanol Effects, Andrew B. Hawkey

Theses and Dissertations--Psychology

Fetal Alcohol Spectrum Disorders (FASD) are a spectrum of anatomical, developmental and neurobehavioral impairments resulting from ethanol (ETOH) exposure during fetal development. Efforts to develop and screen novel pharmacotherapies against fetal ETOH effects depend heavily upon rodent models to provide indicators of the safety and efficacy of such compounds, in addition to helping better understand the underlying mechanisms to develop and test these pharmacotherapies. The following experiments describe the development of a novel mouse model of FASD using behavioral batteries to assess behavioral or cognitive deficits in juvenile and adolescent offspring (Experiment 1, Experiment 2) and whether deficits with this …

Too Pretty For Homework: The Academic Correlates Of Sexualized Gender Stereotypes Among Adolescent Girls, Andrew A. Nelson

Theses and Dissertations--Psychology

Girls grow up in a culture of ubiquitous female sexualization, and this culture propagates stereotypes that could interfere with their academic outcomes. The current study examined the academic correlates of these sexualized gender stereotypes (SGS) among early adolescent girls. Girls (N = 99) aged 11 to 14 (M_age = 12.4 years, SD = .57 years) completed a survey assessing their academic performance, attitudes, and beliefs. The survey also assessed the degree to which girls believed that boys and girls should act in accordance with these sexualized gender stereotypes. Results indicated that higher endorsement of sexualized gender stereotypes …

Internalizing And Externalizing Dysfunction: An Integrative Model Of Adolescent Drinking, Leila Guller

Theses and Dissertations--Psychology

Separate externalizing and internalizing pathways to problem drinking have been described. However, internalizing and externalizing are substantially correlated, thus, there is good reason to believe that these two forms of dysfunction behaviors do not operate independently.

We tested an integrative developmental model of transactions among internalizing symptomatology, externalizing personality, and psychosocial learning in the prediction of both drinking problems and future internalizing symptoms. To do so, we studied a large sample (n = 1910, 49.9% female) of children over a critical developmental period, from the spring of 5th (last year elementary school) grade through the spring of 9th grade (first …
