Perceptions Of The Voluntarily Childless: The Negative Stigma Of An Unconventional Ideal, Alyssa N. Hook

Psychology and Child Development

This study examined the potential implications of religious affiliation on perceptions of voluntarily childless couples. Undergraduate students were given a vignette about an adult couple that either had children or that was childless, and were subsequently asked to complete questionnaires that rated the couple on a variety of personality dimensions. It was predicted that individuals who identify with pronatalist religious sects have more negative perceptions of those who are childless. There was a significant contrast in the views that Christian individuals held toward couples that were voluntarily childless versus those that had two children, suggesting that this religious affiliation is …

Spatial Ecology Of White-Tailed Deer Fawns In The Northern Great Plains: Implications Of Loss Of Conservation Reserve Program Grasslands, Troy W. Grovenburg, Robert W. Klaver, Jonathan A. Jenks

Natural Resource Management Faculty Publications

Few studies have evaluated how wildlife, and white-tailed deer (Odocoileus virginianus) in particular, respond to Conservation Reserve Program (CRP) grasslands. We conducted a 3-year study (2007– 2009) to determine the influence of CRP on fawn ecology during a time of declining CRP enrollment. We captured and radiocollared 81 fawn white-tailed deer during 15 May to 15 June 2007–2009 in north-central South Dakota, collected 6,505 locations, and documented 70 summer home ranges. Mean summer home ranges increased temporally during 2007–2009 (P < 0.001) and corresponded to a 41% loss of CRP grasslands in the area (2.3% loss in land cover and approx. 21% loss in cover habitat in the study area) over the duration of the study. Additionally, mean movement between daily locations increased (P < 0.001) from 2007 to 2009. Analysis of covariance models indicated that change in CRP influenced home-range size, and change in CRP and wheat influenced daily movement. Smaller home ranges and reduced movements were associated with greater quantity of CRP available to fawns, and increased movements were associated with more acreage of wheat available to fawns. Fawns shifted resource selection during the summer at a mean age ranging from 48.8 days to 58.6 days, and this shift was associated with height of corn (83–87 cm). During early summer, fawns consistently selected for CRP; selection of wheat progressed temporally from avoidance in 2007 to selection in 2009. During late summer, fawns consistently selected for corn habitat and used CRP at least in proportion to its availability. Reduction in CRP-grasslands seemed to increase fawn home-range size and daily movements and, influenced change in resource selection to wheat. Current legislation mandates continued decrease in CRP enrollment and concomitant increase in the planting of corn for ethanol production. Management of habitat throughout the grasslands of the Northern Great Plains that maximizes cover habitats would provide neonates with adequate cover for protection from predators.

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

This study aimed to determine the antibiotic and bacteriocin sensitivity of Listeria monocytogenes strains isolated from animal derived foods. With disc diffusion assay, all fourteen L. monocytogenes strains were suscepti-ble to the antibiotics, including penicillin G, vancomycin, tetracycline, chloramphenicol, rifampicin, erythromycin, gentamicin and trime- thoprim. However, the percentages of fosfomycin and streptomycin resistances were 92.9% and 7.1%, respectively. Multiple resistances were not observed among the tested strains. The results of well diffusion assays showed that all strains were inhibited by the cell-free supernatant of a bacteriocin-producing strain, Pediococcus acidilactici 13, with the inhibition zones ranging from 16.00 to 24.50 mm. …

The Structural Role Of Private Enforcement Mechanisms In Public Law, J. Maria Glover

William & Mary Law Review

The American regulatory system is unique in that it expressly relies on a diffuse set of regulators, including private parties, rather than on a centralized bureaucracy for the effectuation of its substantive aims. In contrast with more traditional conceptions of private enforcement as an ad hoc supplement to public law, this Article argues that private regulation through litigation is integral to the structure of the modern administrative state. Private litigation and the mechanisms that enable it are not merely add-ons to our regulatory regime, much less are they fundamentally at odds with it. Yet, mechanisms of enforcement attendant to private …

Soil Bacterial Communities Of A Calcium-Supplemented And A Reference Watershed At The Hubbard Brook Experimental Forest (Hbef), New Hampshire, Usa, Ganapathi Sridevi, Rakesh Minocha, Swathi A. Turlapati, Katherine C. Goldfarb, Eoin L. Brodie, Louis S. Tisa, Subhash C. Minocha

New Hampshire Agricultural Experiment Station Publications

Soil Ca depletion because of acidic deposition-related soil chemistry changes has led to the decline of forest productivity and carbon sequestration in the northeastern USA. In 1999, acidic watershed (WS) 1 at the Hubbard Brook Experimental Forest (HBEF), NH, USA was amended with Ca silicate to restore soil Ca pools. In 2006, soil samples were collected from the Ca-amended (WS1) and reference watershed (WS3) for comparison of bacterial community composition between the two watersheds. The sites were about 125 m apart and were known to have similar stream chemistry and tree populations before Ca amendment. Ca-amended soil had higher Ca …

First Language Use By Adequate Formal Schooling Adult English Language Learners In A University English Language Institute, Joel S. Garza

Theses and Dissertations - UTB/UTPA

In their pursuit of a better way of life, immigrants who arrive in this country are faced with many challenges. One important challenge is their need to adapt to a new society that requires them to learn English as a second language (ESL). As adult learners enter ESL programs, they are confronted with a common sense belief that the exclusion of their native language (L1) and the exclusive use of the target language (TL) in their instruction is the best approach to learn English. Whether immigrant students are educated or not in their home countries, they face the double task …

Moving Beyond Dichotomies: How The Intersection Of Race, Class And Place Impacts High School Graduation Rates For African American Students, Heather L. Storer, Joseph A. Mienko, Yu-Ling Chang, Ji Young Kang, Christina Miyawaki, Katie Schultz

The Journal of Sociology & Social Welfare

Over thirty years ago, William Julius Wilson declared that class trumped race as the more significant determinant of social mobility and economic opportunity. Despite the acclaim and scrutiny for Wilson's work, the United States has grown increasingly divided by intersecting factors of race, class and other demographic factors such as place (Massey, 2007). These divisions are especially evident in the public education system. We analyze how race, class and place interact to predict high school graduation rates in a national sample of schools and students. Results confirm that a singular focus on race, class, or locale is insufficient to explain …

Department of Entomology: Faculty Publications

Spatial genetic variability of the fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), was studied by collecting samples from 31 locations in the United States, Argentina, Panama, and Puerto Rico, and then using amplified fragment length polymorphism to detect genetic variation. Analysis of molecular variance showed significant genetic variation in fall armyworm among all (28%) sample locations and individuals within (71%) sample locations; genetic variation of fall armyworm was minimal between sample locations grouped into regions. The pairwise fixation index (F_ST) comparisons showed significant genetic differentiation (0.288) among the 31 locations. However, dendrograms of results from cluster …

Genetic Differentiation Of Western Corn Rootworm Populations (Coleoptera: Chrysomelidae) Relative To Insecticide Resistance, Hong Chen, Haichuan Wang, Blair D. Siegfried

Department of Entomology: Faculty Publications

Abstract

As the single most important pest of field corn, Zea mays L., throughout most of the Corn Belt, the western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), has undergone repeated selection for resistance to a variety of insecticides that persist widely among Nebraska populations. In this study, we used 11 microsatellite markers to genotype two populations with high levels of resistance to methyl-parathion and aldrin (Polk and Stromsburg), two populations with low and intermediate levels of resistance (Mead and Clay Center) from Nebraska, and one population from outside the Corn Belt (Safford, Arizona). The genetic diversity measured by …

Bean Leaf Beetle (Coleoptera: Chrysomelidae) And Bean Pod Mottle Virus In Soybean: Biology, Ecology, And Management, Buyung A. R. Hadi, Jeffrey D. Bradshaw, Marlin E. Rice, John J. Hill

Department of Entomology: Faculty Publications

Bean leaf beetle, Cerotoma trifurcata (Förster), is a pest of soybean found in many production areas in the United States. The bean leaf beetle larvae feed on soybean root nodules, whereas the adults feed on the above ground parts of soybean such as cotyledon, leaves, and pods. Bean leaf beetle is also a very efficient vector of Bean pod mottle virus, a widespread virus of soybean in the south and southeastern United States with recent expansion into the north central region of the country. This article summarizes bean leaf beetle biology, ecology, and its impact on soybean production in the …

Plant Wounding And Ophiostoma Mitovirus 3a (Omv3a) Influence Infection Of Creeping Bentgrass By Sclerotinia Homoeocarpa, Angela M. Orshinsky, Michael J. Boehm, Greg J. Boland

Department of Plant Pathology: Faculty Publications

Colonization and lesion development by virulent, asymptomatic and hypovirulent isolates of Sclerotinia homoeocarpa on nonwounded (NW) and wounded (W) leaves of creeping bentgrass were characterized. Hypovirulent and asymptomatic isolates contain the fungal virus, Ophiostoma mitovirus 3a, and virulent isolates are virus-free. On NW leaves, all isolates infected leaves with appressoria along cell walls and through stomata by 48 hours post-inoculation (hpi). Inter- and intracellular hyphae formed on heavily colonized, NW leaves at 96 hpi. Wound-inoculated grass had a colonization front characterized by inter- and intracellular hyphal colonization within nonsymptomatic tissues at 8 hpi by direct infection of the wound …

Weak Polygyny In California Sea Lions And The Potential For Alternative Mating Tactics, Ramona Flatz, Manuela González-Suárez, Julie K. Young, Claudia J. Hernández-Camacho, Aaron J. Immel, Leah R. Gerber

United States Department of Agriculture Wildlife Services: Staff Publications

Female aggregation and male territoriality are considered to be hallmarks of polygynous mating systems. The development of genetic parentage assignment has called into question the accuracy of behavioral traits in predicting true mating systems. In this study we use 14 microsatellite markers to explore the mating system of one of the most behaviorally polygynous species, the California sea lion (Zalophus californianus). We sampled a total of 158 female-pup pairs and 99 territorial males across two breeding rookeries (San Jorge and Los Islotes) in the Gulf of California, Mexico. Fathers could be identified for 30% of pups sampled at …

Vegetative filters have been found to significantly reduce nutrient loads in runoff. This study was conducted to: (1) evaluate the effects of a narrow wheat strip, varying manure application rates, and different overland flow rates on runoff nutrient loads following application of beef cattle manure; (2) determine the upper capacity of a narrow wheat strip to reduce nutrient loads by applying excessive amounts of manure; and (3) compare the effectiveness of narrow wheat strips and grass hedges in reducing runoff nutrient loads. A 1.4 m wide strip of actively growing winter wheat was located at the bottom of selected 0.75 …

Sexual Behavior Of Hiv-Positive Adults Not Accessing Hiv Treatment In Mombasa, Kenya: Defining Their Prevention Needs, Avina Sarna, Stanley Luchters, Melissa Pickett, Matthew Chersich, Jerry Okal, Scott Geibel, Nzioki Kingola, Marleen Temmerman

Population Health, East Africa

Background: HIV spread continues at high rates from infected persons to their sexual partners. In 2009, an estimated 2.6 million new infections occurred globally. People living with HIV (PLHIV) receiving treatment are in contact with health workers and therefore exposed to prevention messages. By contrast, PLHIV not receiving ART often fall outside the ambit of prevention programs. There is little information on their sexual risk behaviors. This study in Mombasa Kenya therefore explored sexual behaviors of PLHIV not receiving any HIV treatment.

Results: Using modified targeted snowball sampling, 698 PLHIV were recruited through community health workers and HIV-positive …

Regulation Of The Vapbc-1 Toxin-Antitoxin Locus In Nontypeable Haemophilus Influenzae, Susan D. Cline, Sehresh Saleem, Dayle A. Daines

Biological Sciences Faculty Publications

Nontypeable Haemophilus influenzae (NTHi) are human-adapted commensal bacteria that can cause a number of chronic mucosal infections, including otitis media and bronchitis. One way for these organisms to survive antibiotic therapy and cause recurrent disease is to stop replicating, as most antimicrobials target essential biosynthetic pathways. Toxin-antitoxin (TA) gene pairs have been shown to facilitate entry into a reversible bacteriostatic state. Characteristically, these operons encode a protein toxin and an antitoxin that associate following translation to form a nontoxic complex, which then binds to and regulates the cognate TA promoter. Under stressful conditions, the labile antitoxin is degraded and the …

Dc Dielectrophoretic Assisted Anti-Fouling Filtration System, Nathan M. Cohen

Master's Theses

Filtration processes, whether on the microfluidic, clinical treatment systems, or industrial scale (e.g., point-of-care diagnostics, dialysis, and biopharmaceutical manufacturing, respectively), are often inseparable from membrane clogging (fouling). As a consequence, most, if not all, filtration systems require frequent maintenance to maintain functionality and efficiency. The thesis of this project hypothesizes that Dielectrophoresis can be combined with standard filtration to reduce filter fouling, extending membrane life, and enabling continuous operation. This project investigates a method to reduce fouling, add specificity and efficiency, and decrease the cost and challenge of filtration based biofluid separations.

To substantiate this thesis, we designed, fabricated, and …

Landbird Response To Fine-Scale Habitat Characteristics Within Riparian Forests Of The Central California Coast, Ronald E. Melcer Jr.

Master's Theses

Riparian corridors in California are known to be an important but reduced and degraded resource for landbirds. In spite of previous research, the habitat characteristics that correlate with high landbird abundance remain poorly understood. In particular, the scale at which predictive models are useful (fine scale, watershed, sub-region or region) is ill defined. Herein, point count-based abundance indices for 8 riparian associated/obligate species with uniform and high detection probabilities are correlated with biotic and abiotic habitat variables: a sums of squares procedure is used to select the top 5 predictive variables for each species, best fit linear models are selected …
