Population And Diet Assessment Of White Bass In Lake Sharpe, South Dakota, Andrew E. Ahrens, Travis W. Schaeffer, Melissa R. Wuellner, David W. Willis

The Prairie Naturalist

White bass (Morone chrysops) have been introduced into all 4 South Dakota Missouri River reservoirs and compose a substantial proportion of the annual recreational harvest. To date, limited studies have examined white bass population dynamics and food habits in South Dakota Missouri River reservoirs. Our objective was to examine population dynamics and food habits of white bass in Lake Sharpe, a South Dakota mainstem Missouri River reservoir. White bass consistently consumed invertebrates during May but switched to a more piscivorous diet later in the growing season; most of the fish consumed were gizzard shad (Dorosoma cepedianum). …

Correlation Of Mature Walleye Relative Abundance To Egg Density, Jordan D. Katt, Casey W. Schoenebeck, Keith D. Koupal, Brian C. Peterson, W. Wyatt Hoback

The Prairie Naturalist

Knowledge of spawning areas can benefit fisheries management (Marsden et al. 1991). Identification of spawning areas allows managers to protect, enhance, and/or restore critical habitat (Gunn et al. 1996, Thompson 2009), examine important biotic and abiotic conditions necessary for reproduction (Quist et al. 2003), and to efficiently collect broodstock for production (Satterfield and Flickinger 1996). The most effective method to directly identify spawning areas of fish with demersal eggs is to sample the substrate for eggs (Marsden et al. 1991). This method has been used to locate spawning areas of several species (Michaletz 1984, Zorn et al. 1998, Martin 2008). …

The Preservation Of Archaeological Records And Photographs, Kelli Bacon

Department of Anthropology: Theses and Student Research

Substantive and organized research about archaeological records and photograph preservation, especially those written by and for archaeologists, are few. Although the Society for American Archaeology has a code of ethics regarding archaeological records preservation, and the federal government has regulations regarding the care and preservation of federally owned archaeological collections, there is a lack of resources. This is detrimental to archaeology because not all archaeologists, given the maturity of the discipline, understand how important it is to preserve archaeological records and photographs. Without documents and photographs from projects, irreplaceable information is lost. This thesis adds to the existing body of …

Recent Legislation To Promote Wind Energy In Nebraska, Ryan Lemke

Department of Environmental Studies: Undergraduate Student Theses

Nebraska is currently ranked 4th in the nation for wind energy potential, but ranks low in actual wind power production. The lack of wind energy production could be the result of Nebraska’s unique public power districts that have eminent domain of distribution and retail sales of electricity in the State. Public Power districts are prohibited from receiving benefits of state and federal tax incentives for the development of wind farms, however some Nebraska power districts still pursue wind energy as a renewable source of energy.

Recent legislation changes, including the passing of laws LB629 and LB1048, have provided the State …

The traditional hunting of dugongs and sea turtles provides not only a food source, but brings prestige to the men who catch them and serves as an educational platform to teach the younger generations about their culture. There are many environmental threats that impact the populations of sea turtles and dugongs though the …

The Post-Nuclear Family And The Depoliticization Of Unplanned Pregnancy In Knocked Up, Juno, And Waitress, Kristen Hoerl, Casey Ryan Kelly

Department of Communication Studies: Faculty Publications

This essay explores three films from 2007, Knocked Up, Juno, and Waitress, which foreground young women’s unplanned pregnancies. These movies depoliticize women’s reproduction and motherhood through narratives that rearticulate the meaning of choice. Bypassing the subject of abortion, the women’s decisions revolve around their choice of heterosexual partners and investment in romantic relationships. Although they question the viability of the nuclear family for single pregnant women, these films represent new iterations of post-feminism that ultimately restore conservative ideas that valorize pregnancy and motherhood as women’s imperatives. We conclude by addressing how these movies present a distorted and …

"For Such Is A Friend Now": Reflection And Revision In Shakespeare's Comic Friendships, Leah Rainell Boudreaux

Master's Theses

In early modem England, "friendship" was a term both flexible and deeply fraught. It could apply to a wide range of relationships, including, for example, those between family members, lords and tenants, or male members of the aristocracy. The ideals associated with friendship at that time had a profound impact on the way that the relationship was represented both in a historical and literary sense. During that time, William Shakespeare crafted remarkable and resonating depictions of friendship which have endured the through the ages. The distinction between Shakespeare's work and the work of other early modem writers lies in the …

Design Charts For Retaining Walls In Seismic Areas, Yingwei Wu, Shamsher Prakash

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Retaining walls have failed either by sliding away from the backfill or due to combined action of sliding and rocking displacements, during earthquakes. Performance based design of the retaining walls in seismic areas must account for the likely displacements, in addition to calculating the usual factors of safety against failure in bearing, sliding and overturning. a realistic model for estimating dynamic displacement has been developed, which accounts for the combined action of sliding and rocking and takes into consideration, non-linear soil stiffness in sliding, and rocking, geometrical and material damping in sliding, and rocking, and coupling effects. This model was …

Cigarette Smoke, Dna Damage And Repair In Human Cervical And Vaginal Cells In Vitro And Ex Vivo., Afsoon Moktar

Electronic Theses and Dissertations

Among gynecological malignancies, carcinoma of the cervix is the leading cancer type worldwide. Conversely, vaginal tumors account for an incidence of approximately 1-2% of lower genital tract malignancies. Interestingly, the major shared risk factor among women with cervical and vaginal tumors is infection with cancer-associated human papillomaviruses (HPVs). In fact, HPV infection is the necessary causative factor in the development and progression of cervical and vaginal neoplasia in the majority of cases. Epidemiological studies support that cervical and vaginal pre-cancerous lesions that are initiated by HPV infection generally regress in the absence of known risk factors such as cigarette smoking. …

Inflammatory Cell Tumor Necrosis Factor Signaling Modulates Post-Infarction Left Ventricular Remodeling., Robert K. Lewis 1977-

Electronic Theses and Dissertations

The fundamental question of the exact nature of the role played by TNF in the failing myocardium remains one of contention. Many preclinical studies have demonstrated beneficial effects with TNF antagonism and recently the dichotomous role played by the two TNF receptors in chronic ischemic injury has come to light. The failing heart has also been determined to have low levels of inflammatory cell infiltration. As these cells are known to be potent producers of inflammatory cytokines, we hypothesized that inflammatory cell localized TNF receptors play an important role in the progression of LV remodeling following ischemic injury. To isolate …
