Testing Cross-Sectional And Prospective Mediators Of Internalized Heterosexism On Heavy Drinking, Alcohol Problems, And Psychological Distress Among Heavy Drinking Men Who Have Sex With Men, Alexis Kuerbis, Ethan Mereish, Marie Hayes, Christine Davis, Sijing Shao, Jon Morgenstern

Publications and Research

Objective: Minority stress theory is often used as a causal explanation for substance use among lesbian, gay, and bisexual populations. This study tested whether drinking to cope with stress (DTC), loneliness, and gay community participation (GCP) mediated the relationship between one type of minority stress (i.e., internalized heterosexism, IH) and behavioral health outcomes. Method: Utilizing secondary data analysis and the PROCESS procedure, relationships between IH, the mediators (DTC, loneliness, and GCP), and outcomes (heavy drinking, alcohol problems, and psychological distress) were explored, both cross-sectionally and in a lagged manner, among both treatment seeking and non-treatment seeking problem drinking men who …

Gene Editing And The Rise Of Designer Babies, Tara R. Melillo

Vanderbilt Journal of Transnational Law

Nearly as long as human beings have existed on this earth, many people have sought out the ideal of perfecting their population: infanticide in Sparta during the Hellenistic era; compulsory sterilization in the 1920s in the United States; and the unimaginable atrocities of the Holocaust in the 1940s in Europe. The goal of alleged perfection leaves many hesitant to repeat the mistakes of our past. Today, a new frontier of science has emerged, gene editing using CRISPR-Cas9, reigniting ethical debate as to how far humans should go in manipulating the population. While many proponents herald this technology as a potential …

The Case For Gmos: Dealing With Clashes Between Property Rights And Health And Safety Concerns, Kline C. Moore

Vanderbilt Journal of Transnational Law

A comparative analysis of international decisions concerning genetically modified organism (GMO) controversies reveals the judicial inconsistency that is often applied to the property rights of GMO producers and researchers. Courts often find that there are strong property right interests in GMOs, but when these rights clash with health and safety concerns, they are often minimized or completely forgotten; therefore, future growth in biotechnology is inhibited. This Note proposes a solution to this issue that better takes into account all stakeholders and allows for future investment and research into GMOs. The solution draws upon the lessons learned from current regulatory and …

Indiscriminate Attacks And The Past, Present, And Future Of The Rules/Standards And Objective/Subjective Debates In International Humanitarian Law, Stephen Townley

Vanderbilt Journal of Transnational Law

Civil society, the United Nations, and others are subjecting the conduct of hostilities to increasing scrutiny. But they often lack access to internal targeting data and therefore frequently render legal judgments based on the effects of attacks or assertions that particular weapons or methods of combat are inherently unlawful. This Article analyzes the historical development of key provisions of international humanitarian law (IHL) within the framework of two perennial legal debates--that between rules and standards and that between objective and subjective tests. It argues that while targeting provisions have generally reflected a balance between those two dyads, the jurisprudence of …

Training Midwives To Perform Basic Obstetric Point-Of-Care Ultrasound In Rural Areas Using A Tablet Platform And Mobile Phone Transmission Technology—A Wfumb Coe Project, Sudhir Vinayak, Joyce Sande, Harvey Nisenbaum, Christian Pállson Nolsøe

Imaging & Diagnostic Radiology, East Africa

Point-of-care ultrasound (POCUS) has become a topical subject and can be applied in a variety of ways with differing outcomes. The cost of all diagnostic procedures including obstetric ultrasound examinations is a major factor in the developing world and POCUS is only useful if it can be equated to good outcomes at a lower cost than a routine obstetric examination. The aim of this study was to assess a number of processes including accuracy of images and reports generated by midwives, performance of a tablet-sized ultrasound scanner, training of midwives to complete ultrasounds, teleradiology solution transmissions of images via internet, …

The widespread influence of miRNAs in many biological processes and characteristic changes in expression profiles make them potential biomarkers for a range of diseases. With recent discoveries highlighting the enrichment of particular circulating miRNAs in plasma under pathological conditions, there has been a push for technological advances in miRNA profiling studies as a diagnostic tool. A standardized, automated, high-throughput method for miRNA isolation from human plasma samples was developed in this study. Samples were subject to full miRNome profiling utilizing RT-qPCR. These unique findings demonstrate that developing a distinct miRNA biomarker profile for heart failure patients is feasible and holds …

Elucidation Of Protein Interactions And The Re-Tuning Of Porphyrin Electronics For Hydroxylases, Steven Charles Ratigan

Theses and Dissertations

Non-Ribosomal Peptide Synthetases (NRPSs) and their exogenous tailoring partners have been heavily studied but not in the context of non-cognate systems. Orf78, a dinuclear iron β-hydroxylase from the lysobacter pathway and homologous to CmlA from the chloramphenicol pathway, is used to test affinities for one native and two non-native T-domains. Results indicate that there is enough difference between Type I and Type II NRPS systems to disfavor common recognition motifs. Additionally, the β-hydroxylase P450sky, from the skyllamycin biosynthetic pathway, is used in conjunction with the NRPS ATdomain NikP1AT from the nikkomycin biosynthetic pathway, in lieu of the homolog P450nikQ. The …

Creating Equitable Access Pathways For All Students In South Carolina? A Study Of Sc International Baccalaureate Diploma Programs, Diane D. Padula

Theses and Dissertations

This case study adds insight to the idea of equitable access as it relates to advanced coursework available to students in public high schools in South Carolina. The International Baccalaureate Diploma Program (IBDP) has become a viable choice since secondary-level magnet programs in SC have taken root for over thirty years. The IBDP originally developed in SC to attract the global elite, however in the recent decade, the IBDP has morphed into a program meant for all students. The concept of IB for All is marketed as a college readiness program within South Carolina IBDP schools. Access is multidimensional; it …

Drivers Of Sediment Accumulation And Nutrient Burial In Coastal South Carolina Residential Stormwater Detention Ponds, William Schroer

Theses and Dissertations

Stormwater detention ponds are widely utilized as control structures to manage runoff waters during storm events. These sediments also represent significant sites of organic carbon and nutrient burial. Here, carbon (C) and nutrient sources and burial rates were determined in 14 residential stormwater detention ponds throughout coastal counties of South Carolina. Bulk sediment accumulation was directly correlated with catchment impervious surface coverage (R2 = 0.90) with sediment accumulation rates ranging from 0.06 to 0.50 cm y-1. These rates of sediment accumulation and subsequent pond volume loss are lower than expected indicating that required maintenance dredging schedules be reassessed. Strong, positive …

Silylation-Based Kinetic Resolution Of 2-Arylcyclohexanols And Understanding Internal Chirality Transmission Via Circular Dichroism, Li Wang

Theses and Dissertations

This work described herein focuses on the silylation-based kinetic resolution methodology developed by the Wiskur group in 2011. It is a powerful method for the separation of a single enantiomer from a mixture of racemic secondary alcohols. Chapter one is a summary of the background and related works of this methodology.

In chapter two, the silylation-based kinetic resolution of various trans 2-arylcyclohexanols will be discussed by employing a p-isopropyl triphenylsilyl chloride as the derivatizing reagent with (-)-benzotetramisole as the catalyst. The diastereoselective and enantioselective of trans alcohols over the cis will be investigated and a facial one-pot reaction sequence will …

Climate Change (Mal)Adaptation As Governmentality: The Case Of The Ada Sea Defense System In The Volta River Delta Of Ghana, Kwame Ntiri Owusu-Daaku

Theses and Dissertations

River deltas are complex natural environments that represent a confluence of many physical, biological and human processes vulnerable to the impacts of climate change. The likely biophysical impacts of climate change on deltas have received substantial attention. However, relatively little attention has been paid to the ways in which the different stakeholders of deltaic environments frame the vulnerability of residents of deltas to climate change. The Volta River Delta (VRD) of Ghana is a compelling site in which to conduct such an examination because of the clear climaterelated changes taking place in the Delta, and the fact that like many …

Archival Resistance: A Comparative Reading Of Ulysses And One Hundred Years Of Solitude, Maria-Josee Mendez

Theses and Dissertations

Much of the comparative scholarship on the works of Gabriel García Márquez assumes the position that he was most significantly influenced by the works of William Faulkner and Ernest Hemingway. However, beyond the citation of techniques shared extensively by other Modernists and dependence upon superficial comparisons between texts, the connections between García Márquez and these writers frequently remain tenuous. I suggest that to privilege Faulknerian or Hemingwayan readings of García Márquez is to overlook his position as a postcolonial Latin American novelist; I therefore consider in relationship with García Márquez the Irish writer James Joyce. Both writers participate in what …

Social Support, Parent Stress, And Child Aggression: A Longitudinal Model Of Family Ecology, Jill B. Lubansky

Theses and Dissertations

In the last few decades, treatment of problem behaviors in children and adolescents has targeted the entire family rather than more traditional methods that targeted the individual child. This approach is rooted in family systems and other ecological research and theory. The social sciences have maintained a long history of inquiry into the relations among social support, stress, and psychopathology. However, few of these inquiries include child outcomes, such as behavior problems, as the psychopathological outcome. Even fewer studies have utilized longitudinal models that have the capacity to accurately reflect the developmental process of stress and psychopathology. In the current …

Challenging Standard Grading Practices: A Qualitative Action Research Study, Brian Andrew Timmons

Theses and Dissertations

The present qualitative Action Research study was conducted to determine students’ perceptions of current teacher grading practices and how a standards-based grading (SBG) report card affected secondary students’ perceptions and understanding of grade fairness and accuracy compared to a standard report card, which reports a single grade that often combines academic achievement with behaviors, attendance, homework completion, deadlines and the like. At the end of the first four-and-a-half week grading period of the fall 2016 semester, a group of tenth-grade English II Honors students were presented with two different report cards, one that utilized a single numerical average and one …

The Influence Of Phytoplankton Size And Community Composition On Carbon Cycling And Planktonic Food Webs In The Sargasso Sea, Bridget Elise Cotti-Rausch

Theses and Dissertations

The Sargasso Sea is a dynamic physical environment located in the western North Atlantic where strong seasonal variability combines with forcing by mesoscale (~100 km) eddies. These drivers determine nutrient, light, and temperature regimes, and ultimate the size, composition and productivity of the phytoplankton community. My general objective was to determine how the structure and function of planktonic communities affected carbon export from the surface ocean in the Sargasso Sea. On four cruises (2011 and 2012; one eddy per cruise), I investigated links between water column structure, plankton community composition, size, and primary production (PP). I then combined PP data …

The Decision-Making Process For Individuals At Risk For Hereditary Diffuse Gastric Cancer, Alexa Prose

Theses and Dissertations

Hereditary diffuse gastric cancer (HDGC) is caused by mutations in the CDH1 gene. Individuals who carry mutations in the CDH1 gene have as high as an 80% lifetime risk for gastric cancer. To reduce the high lifetime risk of gastric cancer, CDH1 mutation carriers are recommended to undergo a prophylactic total gastrectomy (TG). Individuals within this at-risk population face a difficult task of deciding whether to have genetic testing for the CDH1 mutation and to have a prophylactic TG. Currently, there is little research that examines the factors influencing decision-making for this population and their specific informational and support needs. …

Sociocultural Context And Determinants Of Treatments For Hemorrhoids Among The Nigerian Police, Oyo State Command, Abolaji Azeez, Uche C. Isiugo-Abanihe

Journal of Social, Behavioral, and Health Sciences

Hemorrhoids or piles, culturally known as Jedijedi among the people of southwestern Nigeria, are an anorectal disease surrounded by misconceptions. The consequences of these misconceptions are enormous. Therefore, the main objective of the present study is to understand the sociocultural explanation of piles among selected personnel of the Nigeria Police Force. We recruited 302 police officers for the exploratory survey through a multistage sampling technique. Five key informants were interviewed at the study area based upon their professions and proximity. Data interpretation was done through chi-square and content analysis. Results indicated a high prevalence (73%) of and misconceptions about hemorrhoids …

The Relationship Between Physical Fitness And School Performance, Jamie A. Donnelly

Journal of Social, Behavioral, and Health Sciences

Past research has indicated a significant relationship between physical fitness and standardized test scores; however, the relationship between physical fitness and other aspects of school performance has yet to be empirically examined in a population specifically composed of middle school girls. Because girls have a harder time transitioning through the middle school years, they are an important group to study in this context. This study examined several factors that contribute to school success, such as classroom behavior, attendance, and grades, in relation to physical fitness among a group of adolescent girls. It was specifically designed to examine the statistical relationship …

Short-Term Electricity Load Forecasting For The Integrated Single Electricity Market (I-Sem), Katie Kavanagh, Martin Barrett, Michael Conlon

Conference papers

The electricity market structure in Ireland is being reconstructed in order to meet with the requirements of the EU Third Energy Package. The forthcoming Integrated-Single Electricity Market (I-SEM) differs from the current market structure in many ways. However this research addresses the issue of balance responsibility under the I-SEM. Given the volatility of prices in the Balancing market, observed in similarly-structured markets around the world, Irish supply companies need to be able to accurately forecast their customers' load in the Day-Ahead market in order to manage risk in the Balancing market. This paper presents a means for suppliers to implement …

Quantifying Current Sediment Deposition, Legacy Sediments, And Pre-Impoundment Vertical Accretion And Carbon Dynamics Following Dam Removal In A Recently Restored Tidal Freshwater Wetland, Melissa J. Davis

Theses and Dissertations

Damming disrupts natural sediment flow to downstream resulting in legacy sediment accumulation. Legacy sediments have been well investigated in streams throughout the Piedmont region; however, there is no research of legacy sediments following dam removal in low-gradient Coastal Plain streams. Research objectives were to: characterize legacy sediments in a low-gradient stream restoration, quantify pre-impoundment accretion and carbon dynamics, and assess current sediment deposition rates via ¹⁴C analyses within sediment cores and sediment collection tiles. Carbon accumulation and accretion rates of modern tidal sediment have reached that of the tidal relic benchmark and current sediment deposition rates are similar between …

Behavioral Responses Of Sub-Adult Atlantic Sturgeon (Acipenser Oxyrinchus Oxyrinchus) To Electromagnetic And Magnetic Fields Under Laboratory Conditions, Andrew Mcintyre Iii

Theses and Dissertations

Electromagnetic fields (EMF) produced by high voltage (HV), submarine transmission cables leading from offshore wind energy generation facilities could affect foraging or migratory behaviors of electro-receptive fishes, including endangered Atlantic Sturgeon. However, no published studies have quantitatively evaluated the possible behavioral effects of EMF exposure on sturgeon during residence in coastal waters. This study evaluated behavioral responses by sub-adult Atlantic Sturgeon to electromagnetic and magnetic fields under controlled laboratory conditions. Fabricated EMF generators were used to emulate a range of field EMF conditions that migratory fishes could encounter in proximity to submarine HV sources. Sensor arrays and digital video recorders …

Altered Gut Microbiome In A Mouse Model Of Gulf War Illness Causes Neuroinflammation And Intestinal Injury Via Leaky Gut And Tlr4 Activation, Firas Alhasson, Suvarthi Das, Ratanesh K. Seth, Diptadip Dattaroy, Varun Chandrashekaran, Caitlin N. Ryan, Luisa S. Chan, Traci Testerman, James Burch, Lorne J. Hofseth, Ronnie Horner, Mitzi Nagarkatti, Prakash Nagarkatti, Stephen M. Lasley, Saurabh Chatterjee

Faculty Publications

Many of the symptoms of Gulf War Illness (GWI) that include neurological abnormalities, neuroinflammation, chronic fatigue and gastrointestinal disturbances have been traced to Gulf War chemical exposure. Though the association and subsequent evidences are strong, the mechanisms that connect exposure to intestinal and neurological abnormalities remain unclear. Using an established rodent model of Gulf War Illness, we show that chemical exposure caused significant dysbiosis in the gut that included increased abundance of phylum Firmicutes and Tenericutes, and decreased abundance of Bacteroidetes. Several gram negative bacterial genera were enriched in the GWI-model that included Allobaculum sp. Altered microbiome caused significant decrease …

Faculty Perceptions Of Teaching Information Literacy To First-Year Students: A Phenomenographic Study, Lorna M. Dawes

University of Nebraska-Lincoln Libraries: Faculty Publications

This study examines faculty perceptions of teaching information literacy and explores the influence of these perceptions on pedagogy. The study adopted an inductive phenomenographic approach, using 24 semi-structured interviews with faculty teaching first-year courses at an American public research university. The results of the study reveal four qualitative ways in which faculty experience teaching information use to first year students that vary within three themes of expanding awareness. The resulting outcome space revealed that faculty had two distinct conceptions of teaching information literacy: (1) Teaching to produce experienced consumers of information, and (2) Teaching to cultivate intelligent participants in discourse …

Where Science Intersects Pop Culture: An Informal Science Education Outreach Program, Raychelle Burks, Kiyomi D. Deards, Erica Defrain

University of Nebraska-Lincoln Libraries: Faculty Publications

Attracting a general audience to STEM topics can be a challenge, and developing engaging and interactive instruction is important for educators in all fields. While many chemical educators have successfully used pop-culture themes to introduce their students to scientific concepts, these encounters are largely limited to formal classroom environments. Inspired by the successes of community science programs such as Science Café and Nerd Nite, science educators from two Nebraska campuses sought to broaden the exposure of their pop-culture themed class lectures, and created the SciPop Talks! program. Now entering its fifth year, this informal educational outreach program has become a …

Persistence Statements: Describing Digital Stickiness, John Kunze, Scout Calvert, Jeremy D. Debarry, Matthew Hanlon, Greg Janée, Sandra Sweat

University of Nebraska-Lincoln Libraries: Faculty Publications

In this paper we present a draft vocabulary for making “persistence statements.” These are simple tools for pragmatically addressing the concern that anyone feels upon experiencing a broken web link. Scholars increasingly use scientific and cultural assets in digital form, but choosing which among many objects to cite for the long term can be difficult. There are few well-defined terms to describe the various kinds and qualities of persistence that object repositories and identifier resolvers do or don’t provide. Given an object’s identifier, one should be able to query a provider to retrieve human- and machine-readable information to help judge …

Microbial Communities Associated With Stable Fly (Diptera: Muscidae) Larvae And Their Developmental Substrates, Erin Scully, Kristina Friesen, Brian Wienhold, Lisa M. Durso

Department of Entomology: Faculty Publications

Bacteria are essential for stable fly (Stomoxys calcitrans (L.)) larval survival and development, but little is known about the innate microbial communities of stable flies, and it is not known if their varied dietary substrates influence their gut microbial communities. This investigation utilized 454 sequencing of 16S and 18S amplicons to characterize and compare the bacterial and eukaryotic microbial communities in stable fly larvae and their developmental substrates. The microbial community of the third-instar stable fly larvae is unambiguously distinct from the microbial community of the supporting substrate, with bacterial communities from larvae reared on different substrates more similar …

Parameters For Successful Parental Rnai As An Insect Pest Management Tool In Western Corn Rootworm, Diabrotica Virgifera Virgifera, Ana Maria Vélez, Elane Fishilevich, Natalie Matz, Nicholas P. Storer, Kenneth E. Narva, Blair D. Siegfried

Department of Entomology: Faculty Publications

Parental RNAi (pRNAi) is an RNA interference response where the gene knockdown phenotype is observed in the progeny of the treated organism. pRNAi has been demonstrated in female western corn rootworms (WCR) via diet applications and has been described as a potential approach for rootworm pest management. However, it is not clear if plant-expressed pRNAi can provide effective control of next generation WCR larvae in the field. In this study, we evaluated parameters required to generate a successful pRNAi response in WCR for the genes brahma and hunchback. The parameters tested included a concentration response, duration of the dsRNA …

Insect And Plant-Derived Mirnas In Greenbug (Schizaphis Graminum) And Yellow Sugarcane Aphid (Sipha Flava) Revealed By Deep Sequencing, Haichuan Wang, Chi Zhang, Yongchao Dou, Bin Yu, Yunfeng Liu, Tiffany Heng-Moss, Guoqing Lu, Michael Wachholtz, Jeffery D. Bradshaw, Paul Twigg, Erin Scully, Nathan Palmer, Gautam Sarath

Department of Entomology: Faculty Publications

Schizaphis graminum (green bug; GB) and Sipha flava (yellowsugarcane aphid; YSA) are two cereal aphid species with broad host ranges capable of establishing on sorghum (Sorghum bicolor) and several switchgrass (Panicum virgatum) cultivars. Switchgrass and sorghum are staple renewable bioenergy crops that are vulnerable to damage by aphids, therefore, identifying novel targets to control aphids has the potential to drastically improve yields and reduce losses in these bioenergy crops. Despite thewealth of genomic and transcriptomic information available from a closely related model aphid species, the pea aphid (Acyrthosiphon pisum), similar genomic information, including the …
