Song Of Wekiva: Florida’S Wild River And Its Democratic Vista, Steve Phelan Jan 2010

Song Of Wekiva: Florida’S Wild River And Its Democratic Vista, Steve Phelan

Faculty Publications

Today hundreds of thousands enjoy the river every year. We are a different breed. When I take our children or my students to the river or walk along its sandy uplands to show them undiscovered and unmapped springs popping out of the ground, they and I are still abiding in a domesticated world that erects a substantial, almost impervious barrier to the wilderness of the river. Nevertheless, that wildness is built unconsciously into our bodies. We are not like the Timucuans, the first humans to come down the St. Johns River and eventually up the Wekiva to the two main …

On The Accuracy Of Explicit Finite-Volume Schemes For Fluctuating Hydrodynamics, Aleksandar Donev, Eric Vanden-Eijnden, Alejandro Garcia, John B. Bell Jan 2010

On The Accuracy Of Explicit Finite-Volume Schemes For Fluctuating Hydrodynamics, Aleksandar Donev, Eric Vanden-Eijnden, Alejandro Garcia, John B. Bell

Faculty Publications

This paper describes the development and analysis of finite-volume methods for the Landau–Lifshitz Navier–Stokes (LLNS) equations and related stochastic partial differential equations in fluid dynamics. The LLNS equations incorporate thermal fluctuations into macroscopic hydrodynamics by the addition of white noise fluxes whose magnitudes are set by a fluctuation-dissipation relation. Originally derived for equilibrium fluctuations, the LLNS equations have also been shown to be accurate for nonequilibrium systems. Previous studies of numerical methods for the LLNS equations focused primarily on measuring variances and correlations computed at equilibrium and for selected nonequilibrium flows. In this paper, we introduce a more systematic approach …


The House In The Market: How Q’Eqchi’ Market Women Convert Money And Commodities Into Persons And Personhood, Sarah Ashley Kistler Jan 2010

The House In The Market: How Q’Eqchi’ Market Women Convert Money And Commodities Into Persons And Personhood, Sarah Ashley Kistler

Faculty Publications

Recent research argues that globalization in Latin America sometimes results in the homogenization of culture and loss of indigenous identity. This paper, however, explores how Q’eqchi’-Maya market women in San Juan Chamelco, Guatemala, generate Q’eqchi’ personhood by embracing the conflicts of value introduced by the confrontation of globalization with longstanding Q’eqchi’ values. I argue that in Chamelco, market women are mediators of value who participate in global capitalism to reinforce the categories that structure indigenous life. Q’eqchi’ women engage in marketing activities not only to accrue capital resources, but also to maintain local values, centered on the junkab’al or “house,” …


Batrachochytrium Dendrobatidis Detected In Amphibians From National Forests In Eastern Texas, Usa, Daniel Saenz, Brendan T. Kavanagh, Matthew Kwiatkowski Jan 2010

Batrachochytrium Dendrobatidis Detected In Amphibians From National Forests In Eastern Texas, Usa, Daniel Saenz, Brendan T. Kavanagh, Matthew Kwiatkowski

Faculty Publications

The amphibian disease chytridiomycosis, caused by the pathogenic fungus Batrachochytrium dendrobatidis (Bd, Longcore et al. 1999), is well known as a major threat to amphibians resulting in mass die-offs and population declines throughout the world (Berger et al. 1998; Blaustein and Keisecker 2002; Daszak et al. 2003; McCallum 2005; Rachowicz et al. 2006). Batrachochytrium dendrobatidis has been detected on amphibians from sites across North America (Ouellet et al. 2005; Woodhams et al. 2008) and appears to be most prevalent in the western and the northeastern United States (Longcore et al. 2007; Schlaepfer et al. 2007). Whereas infected anurans also have …

Development And Characterization Of 16 Microsatellite Markers For The Louisiana Pine Snake, Pituophis Ruthveni, And Two Congeners Of Conservation Concern, Matthew Kwiatkowski, Christopher M. Somers, Ray G. Poulin, D. Craig Rudolph, Jessica Martino, Tracey D. Tuberville, Cris Hagen, Stacey L. Lance

Faculty Publications

We isolated and characterized 16 microsatellite loci from the Louisiana pine snake, Pituophis ruthveni. Loci were screened in 24 individuals from locations throughout its distribution in Louisiana and Texas. The number of alleles per locus ranged from 4 to 12, observed heterozygosity ranged from 0.200 to 0.875, and the probability of identity ranged from 0.043 to 0.298. We examined cross-species amplification at these loci in P. catenifer (bullsnakes and gopher snakes) and P. melanoleucus (pine snakes). These new markers provide tools for examining the conservation genetics of this species complex. Louisiana pine snakes face numerous threats: population densities are extremely …


Mechanistic And Computational Studies Of Oxidatively-Induced Aryl-Cf3 Bond Formation At Palladium, J. Brannon Gary Jan 2010

Mechanistic And Computational Studies Of Oxidatively-Induced Aryl-Cf3 Bond Formation At Palladium, J. Brannon Gary

Faculty Publications

This article describes the rational design of 1st generation systems for oxidatively-induced Aryl– CF3 bond-forming reductive elimination from PdII. Treatment of (dtbpy)PdII(Aryl)(CF3) (dtbpy = di-tert-butylbipyridine) with NFTPT (N-fluoro-1,3,5-trimethylpyridium triflate) afforded the isolable PdIV intermediate (dtbpy)PdIV(Aryl)(CF3)(F)(OTf). Thermolysis of this complex at 80 °C resulted in Aryl–CF3 bond-formation. Detailed experimental and computational mechanistic studies have been conducted to gain insights into the key reductive elimination step. Reductive elimination from this PdIV species proceeds via pre-equilibrium dissociation of TfO− followed by Aryl–CF3 coupling. DFT calculations reveal that the transition state for Aryl–CF3 bond formation involves the CF3 acting as an electrophile with the …

Pharmaceutical Crops: An Overview, Shiyou Li, Wei Yuan, Peiying Yang, Mikhail Antoun, Michael Balick, Gordon Cragg Jan 2010

Pharmaceutical Crops: An Overview, Shiyou Li, Wei Yuan, Peiying Yang, Mikhail Antoun, Michael Balick, Gordon Cragg

Faculty Publications

Pharmaceutical crops is an ambiguous term used by biologists and chemists for different categories of plants. We define pharmaceutical crops as those cultivated species that are used for extraction or preparation of therapeutic substances such as active pharmaceutical ingredients (APIs), excipients used in pharmaceutical formulations, vaccines and antibodies, as well as other therapeutic proteins. Based on the type of pharmaceutical product, these crops can be classified into three distinct yet sometimes overlapping categories: crops for the production of small therapeutic molecules (STMs), large therapeutic molecules (LMTs), or standard therapeutic extracts (STEs). This review briefly discusses the relationships of pharmaceutical crops …

Two new sesquiterpenes, sarcandralactones A (1) and B (2), and five new dimeric sesquiterpenoids, sarcandrolides A-E (3-7), along with 10 known compounds were isolated from the whole plants of Sarcandra glabra. Their structures were elucidated on the basis of spectroscopic analysis. Some of the new isolates exhibit significant cytotoxicities when tested against a small panel of tumor cell lines.


Split-Season Herbaceous Weed Control For Full-Season Seedling Performance, Jimmie L. Yeiser, Andrew W. Ezell Jan 2010

Split-Season Herbaceous Weed Control For Full-Season Seedling Performance, Jimmie L. Yeiser, Andrew W. Ezell

Faculty Publications

Results from four loblolly pine (Pinus taeda L.) sites, one in each of MS and TX in 2001 and again in 2002, are presented. Twelve herbicide treatments and an untreated check were tested. Herbicide treatments were applied early (mid- March), late (mid-May), both timings, or not at all to achieve, early- late-, full-season, or no weed control. When averaged across all four sites and compared to the early treatment, bare ground was less from April through July and April through November on late treated and untreated plots, respectively. Full-season weed control provided numerically more bare ground than other treatments. When …


White-Tailed Deer Antler Research: A Response To Demarais And Strickland, Ben Koerth, James Kroll Jan 2010

White-Tailed Deer Antler Research: A Response To Demarais And Strickland, Ben Koerth, James Kroll

Faculty Publications

Demarais and Strickland presented several questions about the scope and validity of conclusions regarding predictability of mature antler size based on yearling antler size and produced a simulation model reported to demonstrate measurement bias in our 2008 study. We believe our conclusions were appropriate with our research hypothesis and demonstrated the assumed differential selection bias by hunters used in Demarais and Strickland was unwarranted. Demarais and Strickland provided no metadata to document the provenance of data used in their model and did not account for location, year, cohort, nutrition of research animals, or loss of individuals from their sample population …

Understory Vegetative Diversity Of Post-Thinned Pine Plantations Treated With Fertilizer, Fire And Herbicide In East Texas, Brian P. Oswald, Dean W. Coble, R R. Botting, Ken W. Farrish, James E. Van Kley

Faculty Publications

This study assessed biodiversity in the understory of two pine plantations where different management tools (fertilizer, prescribed burning, and herbicide application) were utilized. During three growing seasons, species, percent cover, and number of individuals, and physical characteristics were recorded. Responses to treatment were examined based on comparison of species richness, evenness, diversity, and importance. Two years after treatment, fertilized plots showed a decline in species richness, evenness, and diversity. Prescribed burning and herbicide treatments increased species richness but decreased species evenness, resulting in no change in diversity index. Herbicide treatment reduced the importance of dominant shrubs and increased the importance …


Homophobia, Heterosexism, And Ambivalence In The Premier Issue Of Sports Illustrated Woman/Sport, Lisa M. Weidman Jan 2010

Homophobia, Heterosexism, And Ambivalence In The Premier Issue Of Sports Illustrated Woman/Sport, Lisa M. Weidman

Faculty Publications

The arrival of a magazine dedicated solely to the world of women's sports was an exciting prospect for fans and proponents of women's sports. But the first issue of Sports Illustrated Women/Sport disappointed many who considered it did not put women's sports in the best possible light, who were worried and disappointed that its editors did not print the best stories or even focus on the most deserving athletes. Lisa Weidman decided to investigate further, using feminist theory and prior research findings to better understand the magazine's messages. Through a critical analysis of the magazine's editorial content - at the …


Alum Application To Improve Water Quality In A Municipal Wastewater Treatment Wetland: Effects On Macrophyte Growth And Nutrient Uptake, Lynette M. Malecki-Brown, John R. White, Hans Brix Jan 2010

Alum Application To Improve Water Quality In A Municipal Wastewater Treatment Wetland: Effects On Macrophyte Growth And Nutrient Uptake, Lynette M. Malecki-Brown, John R. White, Hans Brix

Faculty Publications

Application of low doses of alum to treatment wetlands to reduce elevated outflow winter phosphorus concentrations were tested in mesocosms vegetated with either Typha domingensis, Schoenoplectus californicus, or submerged aquatic vegetation (SAV) (Najas guadalupensis-dominated). Alum was pumped to experimental units at a rate of 0.91 g Al m-2 d-1 and water quality monitored for 3 months. The alum application significantly improved the outflow water quality and overall the growth of the plants was unaffected by the alum application. Biomass and growth varied between species and through time, but no significant effects of alum application were detected. The concentrations …


Dynamics And Distribution Of Natural And Human-Caused Hypoxia, N N. Rabalais, R J. Diaz, L A. Levin, R. Eugene Turner, N N. Rabalais, J Zhang Jan 2010

Dynamics And Distribution Of Natural And Human-Caused Hypoxia, N N. Rabalais, R J. Diaz, L A. Levin, R. Eugene Turner, N N. Rabalais, J Zhang

Faculty Publications

Water masses can become undersaturated with oxygen when natural processes alone or in combination with anthropogenic processes produce enough organic carbon that is aerobically decomposed faster than the rate of oxygen re-aeration. The dominant natural processes usually involved are photosynthetic carbon production and microbial respiration. The re-supply rate is indirectly related to its isolation from the surface layer. Hypoxic water masses (< 2 mg L-1, or approximately 30% saturation) can form, therefore, under 'natural' conditions, and are more likely to occur in marine systems when the water residence time is extended, water exchange and ventilation are minimal, stratification occurs, and where carbon production and export to the bottom layer are relatively high. Hypoxia has occurred through geological time and naturally occurs in oxygen minimum zones, deep basins, eastern boundary upwelling systems, and fjords. Hypoxia development and continuation in many areas of the world's coastal ocean is accelerated by human activities, especially where nutrient loading increased in the Anthropocene. This higher loading set in motion a cascading set of events related to eutrophication. The formation of hypoxic areas has been exacerbated by any combination of interactions that increase primary production and accumulation of organic carbon leading to increased respiratory demand for oxygen below a seasonal or permanent pycnocline. Nutrient loading is likely to increase further as population growth and resource intensification rises, especially with increased dependency on crops using fertilizers, burning of fossil fuels, urbanization, and waste water generation. It is likely that the occurrence and persistence of hypoxia will be even more widespread and have more impacts than presently observed. Global climate change will further complicate the causative factors in both natural and human-caused hypoxia. The likelihood of strengthened stratification alone, from increased surface water temperature as the global climate warms, is sufficient to worsen hypoxia where it currently exists and facilitate its formation in additional waters. Increased precipitation that increases freshwater discharge and flux of nutrients will result in increased primary production in the receiving waters up to a point. The interplay of increased nutrients and stratification where they occur will aggravate and accelerate hypoxia. Changes in wind fields may expand oxygen minimum zones onto more continental shelf areas. On the other hand, not all regions will experience increased precipitation, some oceanic water temperatures may decrease as currents shift, and frequency and severity of tropical storms may increase and temporarily disrupt hypoxia more often. The consequences of global warming and climate change are effectively uncontrollable at least in the near term. On the other hand, the consequences of eutrophication-induced hypoxia can be reversed if long-term, broad-scale, and persistent efforts to reduce substantial nutrient loads are developed and implemented. In the face of globally expanding hypoxia, there is a need for water and resource managers to act now to reduce nutrient loads to maintain, at least, the current status.

Targeted Reform Of Commercialized Intercollegiate Athletics, Matthew J. Mitten, James L. Musselman, Bruce W. Burton Jan 2010

Targeted Reform Of Commercialized Intercollegiate Athletics, Matthew J. Mitten, James L. Musselman, Bruce W. Burton

Faculty Publications

This Article observes that American society’s passion for intercollegiate sports competition is an extremely powerful, naturally evolved cultural force. The marketplace responds to cultural forces, and the commercialization of college sports directly reflects the marketplace realities of our society. For example, colleges and universities rationally utilize their intercollegiate athletic programs, particularly NCAA Division 1 FBS football and basketball, as a means to achieve a wide range of legitimate objectives of higher education. Thus, the authors advocate that university athletic department revenues should continue to be exempt from federal taxation, specifically the unrelated business income tax (UBIT), despite the increasingly commercialized …


Thoughts On Preemption In The Wake Of The Levine Decision, Erika Lietzan, Sarah E. Pitlyk Jan 2010

Thoughts On Preemption In The Wake Of The Levine Decision, Erika Lietzan, Sarah E. Pitlyk

Faculty Publications

This article discusses the prospects for preemption doctrine in the wake of the Supreme Court’s decision in Wyeth v. Levine. Part I describes the Levine decision. Part II examines the majority’s holding as it relates to impossibility preemption and considers the future of the doctrine in failure-to-warn suits after Levine. We argue that the announced standard for impossibility preemption — the clear evidence standard — should be interpreted reasonably and not in a manner that effectively eviscerates the doctrine. We also describe other instances of impossibility in the food and drug regulatory context that were not presented to the Court. …

The purpose of this study was to begin the development of a broad model that could examine the structural relationships between family leisure involvement, family functioning, family communication, family leisure satisfaction, and satisfaction with family life among a large sample of families (n = 898) from the United States. Findings from both parent and youth perspectives were consistent with previous studies that examined the same variables individually and provided a possible picture of how these family variables might relate to one another in the broader context of family leisure. Slight differences between the parent and youth models added further insight …


Litigation, Integration, And Transformation: Using Medicaid To Address Racial Inequities In Health Care, Ruqaiijah Yearby Jan 2010

Litigation, Integration, And Transformation: Using Medicaid To Address Racial Inequities In Health Care, Ruqaiijah Yearby

Faculty Publications

Using a public health policy perspective, this article examines the persistence of racial inequities in nursing homes and prescribes a solution to address these inequities. I use empirical data to prove the persistence of racial inequities in health care, analyze the government policies that allow racial inequities to continue, and provide a solution of regulatory integration. Specifically, I propose that civil rights enforcement be integrated with the nursing home enforcement system, which has been aggressively enforced and monitored. There are many strategies that may lead to the adoption of this system. One such strategy is using the Medicaid Act to …


Scientific Fraud, Paul C. Giannelli Jan 2010

Scientific Fraud, Paul C. Giannelli

Faculty Publications

Although scientific fraud is rare, when it occurs, it needs to be identified and documented. This article discusses two of the most notorious cases in forensic science. Part I focuses on the misconduct of Fred Zain, a serologist with the West Virginia State Police crime laboratory and later with the County Medical Examiner’s laboratory in San Antonio, Texas. Part II examines the misconduct of Joyce Gilchrist, a forensic examiner with the Oklahoma City Police Department.
