Examining the Impact of Parental Socialization on the Coping Styles of Black Graduate Students Faced with Microaggressions

This article explores case examples of two graduate students who endure microaggressions from their math professor at a predominantly White university. The role that parental socialization plays in how these students developed their racial identities and the coping strategies they employed, is analyzed through the lens of Triple Quandary theory (Boykin and Toms 1 985). Findings from this investigation suggest that parental socialization is critical in preparing these students to cope with and respond to microaggressions in protective and adaptive ways. This paper illuminates coping styles, although divergent, that served these graduate students\u27 needs and protected their individual racial identities. Further, the support these students received from their faculty advisor who is also Black, exemplifies the importance of mentorship and advocacy from faculty of color to Black college students\u27 success. Direction for continuity in parental teachings for K-12 and university level educators are discussed

HABITAT UTILIZATION BY THE TEXAS HORNED LIZARD (PHRYNOSOMA CORNUTUM) FROM TWO SITES IN CENTRAL TEXAS

The Texas Horned Lizard (Phrynosoma cornutum) is found in a variety of habitats. Although several studies have been conducted on habitat use by this species, none have been performed in central Texas, a more mesic habitat than most of those previously studied. This area is of special interest because horned lizard populations have been experiencing sharp declines in central Texas over the last approximately 50 years. We collected habitat data at two sites in central Texas, Camp Bowie and Blue Mountain Peak Ranch. Microhabitat data included canopy cover and ground cover from digitized photographs of Daubenmire quadrats; macrohabitat variables included vegetation height and length, cactus height, soil penetrability, woody plant species richness, tree density, tree diameter at breast height (DBH), and density of ant mounds collected along 100-m by 2-m transects. Similar patterns of habitat use were observed between the two sites. At Blue Mountain Peak Ranch, lizards appeared to be located in areas with a diversity of ground cover types, as observed in previous studies. At Camp Bowie, vegetation encroachment limited lizards in some areas to the use of roads and road margins. Implementation of prescribed burns or other vegetation management could create the preferred ground cover mosaic at such sites

Operator Evolution via the Similarity Renormalization Group I: The Deuteron

Similarity Renormalization Group (SRG) flow equations can be used to unitarily soften nuclear Hamiltonians by decoupling high-energy intermediate state contributions to low-energy observables while maintaining the natural hierarchy of many-body forces. Analogous flow equations can be used to consistently evolve operators so that observables are unchanged if no approximations are made. The question in practice is whether the advantages of a softer Hamiltonian and less correlated wave functions might be offset by complications in approximating and applying other operators. Here we examine the properties of SRG-evolved operators, focusing in this paper on applications to the deuteron but leading toward methods for few-body systems. We find the advantageous features generally carry over to other operators with additional simplifications in some cases from factorization of the unitary transformation operator.Comment: 33 pages, 19 figures. Improved figures 17 and 18. Expanded comments on OPE in tex

Intersex wildlife as sentinels for human health and endocrine disruption near Superfund sites: A Systematic Review

Fish and wildlife are often used as sentinels for human health. This systematic review examines one aspect of wildlife health, intersex (both ovarian and testicular tissue) animals and their prevalence or severity near Superfund sites (EPA designated toxic waste sites). The body of evidence demonstrates some evidence of this indicator and more research is needed, specifically a meta-analysis that is outside the scope of this study

Synthesis and evaluation of halogenated nitrophenoxazinones as nitroreductase substrates for the detection of pathogenic bacteria

The synthesis and microbiological evaluation of 7-, 8- and 9-nitro-1,2,4-trihalogenophenoxazin-3-one substrates with potential in the detection of nitroreductase-expressing pathogenic microorganisms are described. The 7- and 9-nitrotrihalogenophenoxazinone substrates were reduced by most Gram negative microorganisms and were inhibitory to the growth of certain Gram positive bacteria; however, the majority of Gram positive strains that were not inhibited by these agents, along with the two yeast strains evaluated, did not reduce the substrates. These observations suggest there are differences in the active site structures and substrate requirements of the nitroreductase enzymes from different strains; such differences may be exploited in the future for differentiation between pathogenic microorganisms. The absence of reduction of the 8-nitrotrihalogenophenoxazinone substrates is rationalized according to their electronic properties and correlates well with previous findings

Access to Environmental Justice in Bangalore: Legal Gateways in Context

This paper forms part of a larger comparative study on Access to Environmental Justice in Asia and Africa. The project involves a comparison of seven cities (Accra, Bangalore, Cape Town, Karachi, Kuala Lumpur, Tokyo, and Xiamen), with a focus upon the extent to which citizens are able to use law and legal institutions to shape the physical environment in which they live. In the research project generally, and in this paper in particular, there is no normative statement of what 'justice' should entail. Rather, our preferred approach is to identify what types of environmental claims are made by citizens, and evaluate the extent to which those claims may be pursued, and are pursued, in a legal context. Nor do we adopt a restrictive definition of 'environment'. Since we are concerned mainly with the perceptions of activists and citizens's groups, the applicable definition of environment must have a subjective element – the environment is what people say it is. For the purposes of comparison, there is a commitment to examine at least four areas of concern: 1) land use and functional or public space, 2) quantity and quality of the water supply, 3) the quality of air, and 4) waste and waste disposal. The purpose of this paper is to examine the context in which the citizens of Bangalore can, and do, seek to use legal gateways to get environmental justice, in order to provide a springboard for further research under the Access to Environmental Justice project. It also offers thoughts on possible avenues for further enhancing access to environmental remedies. This account is based upon relevant legislation, newspaper accounts, and a series of personal interviews conducted by Amanda Perry in April-June 1995 and Michael Anderson in March 1996. Finally, it should be added that this paper represents a snapshot of work in progress, and that a more detailed set of findings will be published at a later date

Development of a Higher Fidelity Model for the Cascade Distillation Subsystem (CDS)

Significant improvements have been made to the ACM model of the CDS, enabling accurate predictions of dynamic operations with fewer assumptions. The model has been utilized to predict how CDS performance would be impacted by changing operating parameters, revealing performance trade-offs and possibilities for improvement. CDS efficiency is driven by the THP coefficient of performance, which in turn is dependent on heat transfer within the system. Based on the remaining limitations of the simulation, priorities for further model development include: center dot Relaxing the assumption of total condensation center dot Incorporating dynamic simulation capability for the buildup of dissolved inert gasses in condensers center dot Examining CDS operation with more complex feeds center dot Extending heat transfer analysis to all surface
