Evaluation Of A Real-Time Polymerase Chain Reaction Assay For Pseudorabies Virus Surveillance Purposes, Eraldo L. Zanella, Laura C. Miller, Kelly M. Lager, Troy T. Bigelow

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Pseudorabies virus (PRV) is the cause of Aujeszky’s disease, a disease that is significant economically for the swine industry worldwide. A real-time polymerase chain reaction (PCR) assay based on the gB and gE genes was used to identify PRV nucleic acid in diagnostic samples. Using virus isolation (VI) as the gold standard, the PCR assay performed well in a variety of diagnostic matrices. Testing was conducted on 1,027 nasal swabs with the following findings: gB sensitivity: 94.6% (95% confidence interval [CI]: 92.3–96.4%), specificity: 71.0% (95% CI: 64.0–77.3%); gE sensitivity: 94.6% (95% CI: 92.3–96.4%), specificity: 79.3% (95% CI: 72.9–84.7%).

Fum And Bik Gene Expression Contribute To Describe Fumonisin And Bikaverin Synthesis In Fusarium Verticillioides, I. Lazzaro, M. Busman, P. Battilani, R. A. E. Butchko

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Fusarium verticillioides is a maize pathogen that produces toxic secondary metabolites, including fumonisins and bikaverin. The regulation of biosynthetic gene expression and the production of these metabolites are not fully understood and in this study we investigated the influence of water activity (0.955 and 0.990) on the expression of 5 genes (FUM3–FUM8–FUM13–FUM14 and BIK1) in F. verticillioides strains after 14 and 21 days incubation. Fumonisin production and biosynthetic gene expression were greatest at a_w=0.990, and the same trend was observed for bikaverin production, and BIK1 expression. FUM3 and FUM14 were the most highly expressed genes and …

Identification Of Gene Clusters Associated With Fusaric Acid, Fusarin, And Perithecial Pigment Production In Fusarium Verticillioides, Daren W. Brown, Robert A. E. Butchko, Mark Busman, Robert H. Proctor

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The genus Fusarium is of concern to agricultural production and food/feed safety because of its ability to cause crop disease and to produce mycotoxins. Understanding the genetic basis for production of mycotoxins and other secondary metabolites (SMs) has the potential to limit crop disease and mycotoxin contamination. In fungi, SM biosynthetic genes are typically located adjacent to one another in clusters of coexpressed genes. Such clusters typically include a core gene, responsible for synthesis of an initial chemical, and several genes responsible for chemical modifications, transport, and/or regulation. Fusarium verticillioides is one of the most common pathogens of maize and …

How (Not) To Talk About Abortion, Meredith J. Harbach

Law Faculty Publications

In this essay, I aim to have a conversation about how we converse- how we talk-about abortion and related issues. In the process, I want to consider how we might come together to discover issues of shared commitment and values and transform the existing abortion debate. I begin with a review of some of the more notable abortion-related rhetoric during the 2012 Virginia General Assembly, and contrast that rhetoric with the discourse in my classroom. I then consider whether and how we might move forward together toward a more meaningful and productive dialogue on these issues.

Undo Undue Hardship: An Objective Approach To Discharging Federal Students Loans In Bankruptcy, Aaron N. Taylor

All Faculty Scholarship

A debtor seeking to discharge student loans in bankruptcy must prove that paying the debt would cause an undue hardship upon him and his dependents. Undue hardship, however, is an undefined concept, flummoxing debtors, creditors and judges alike. The result of this ambiguity is rampant inconsistency in the manners in which similarly-situated debtors (and creditors) are treated by the courts. This article argues that the undue hardship standard should be replaced by a framework that uses debt service thresholds to determine the propriety of federal student loan bankruptcy discharges. Eligibility for discharge would depend on outstanding loan amounts, debtor income …

Mitigating Agrichemicals From An Artificial Runoff Event Using A Managed Riverine Wetland, Richard E. Lizotte Jr., F. Douglas Shields Jr, Justin N. Murdock, Robert Kröger, Scott S. Knight

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

We examined the mitigation efficiency of a managed riverine wetland amended with a mixture of suspended sediment, two nutrients (nitrogen and phosphorus), and three pesticides (atrazine, metolachlor, and permethrin) during a simulated agricultural runoff event. Hydrologic management of the 500 m-long, 25 mwide riverine wetland was done by adding weirs at both ends. The agrichemical mixture was amended to the wetland at the upstream weir simulating a four-hour, ~1 cm rainfall event from a 16 ha agricultural field. Water samples (1 L) were collected every 30 min within the first 4 h, then every 4 h until 48 h, and …

Law Faculty Publications

On May 31, 2010, in the early hours of the morning, Israeli Defense Forces boarded and occupied a flotilla of six vessels seventy-two nautical miles from the coast of Gaza. The flotilla carried food and other supplies to Gaza, which was under a naval blockade. During the incident, nine passengers were killed and several others wounded. In the aftermath, a key question that emerged was what body of law applied to the incident? Was it subject to human rights law, international humanitarian law, or some mix of the two?

This same question has been at the heart of ongoing debates …

Growing Health: Community Gardens And Their Effects On Diet, Physical And Mental Health And Community, Brittany Minnick Hanson

Electronic Theses and Dissertations

Recently, research on community gardens and their benefits to health and community has become very popular. However, this influx of research has failed to investigate challenges to successful community gardening. Some articles examine issues between community gardeners and the land owners, but other than these conflicts community garden challenges, like lack of participation and quality leadership, have not been discussed in the literature (Draper and Freedman, 2010). To allow future gardens to be as successful as possible it is important to identify potential obstacles. Additionally, it is just as important to continue to examine possible benefits, for example, physical activity …

Cross-Sectoral Coordination Of Disaster Relief, Isabella M. Nolte, Eric C. Martin, Silke Boenigk

Faculty Journal Articles

Coordinating organizational activity across different sectors is crucial in disaster management. We analysed the response of 291 aid workers to the Haiti earthquake in 2010 and found that common incentives and a high degree of equality among aid organizations positively affected perceived network coordination. Large and public organizations were more likely to take leadership roles and high numbers of public organizations involved in the disaster response network led to improved network coordination. These results indicate the need for mechanisms that enable smaller and non-profit organizations to participate in network coordination and leadership.

Age As A Factor In Inter-Tissue Spacing Of Stable Carbon Isotope Values In Juvenile Human Remains From The Dakhleh Oasis, Egypt, Annie Laurie Norris

Electronic Theses and Dissertations

Although stable isotope analysis is routinely utilized in bioarchaeology and relies on principles that are well-understood, there are still fundamental issues that have not been thoroughly investigated. This thesis examines the relationship between inter-tissue spacing of carbon stable isotope values (δ13C) and age in juvenile human remains. Analyses of tissues within the same individual reveal disparate isotopic values for a variety of physiological and biological reasons discussed herein. This project examines the distance between the δ13C values in bone collagen, skin, hair, and nail, and examines how these distances vary between different age groups, utilizing data collected from 52 well-preserved …

The Political Ontology Of Race, Michael James

Faculty Journal Articles

Race theory is dominated by two camps. Eliminativists rely on a biological ontology, which contends that the concept of race must be biologically grounded, in order to repudiate the very term, on grounds that it is epistemologically vacuous and normatively pernicious. Conservationists use a social ontology, in which race is based on social practices, in order to retain racial categories in remedial social policies, such as affirmative action and race-based political representation. This article attempts to reorient this debate in two ways. First, it challenges the idea that racial identity is entirely unchosen by defending a political ontology of race …

Subsurface Phosphorus Transport And Scale Dependent Phosphorus Leaching In Alluvial Floodplains, Derek Michael Heeren

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Increased nutrient loads have resulted in several adverse impacts on surface water quality, including excessive algal growth, fish kills, and drinking water taste and odor issues across the United States and especially in the Ozark ecoregion of northeastern Oklahoma and northwestern Arkansas. Nitrogen is a concern, but phosphorus (P) is generally considered the limiting nutrient in most surface water systems. Scientists and engineers need to identify critical nutrient source areas and transport mechanisms within a catchment in order to cost effectively protect and enhance drinking water systems, recreation activities, and aquatic ecosystems. While surface runoff is considered to be the …

Prescription Drug Misuse Among College Students: An Examination Of Sociological Risk Factors, William C. Watkins

Electronic Theses and Dissertations

Prescription drug misuse (PDM), defined as use without a prescription or solely for the feeling or experience caused by the drug, has become a popular topic among substance use researchers. While the vast majority of studies on the topic tackle epidemiological questions surrounding PDM, there is a notable lack of studies that look specifically at risk factors rooted in sociological/criminological theories. The current research seeks to bridge this gap in the literature by examining theoretically based explanations for PDM among college students utilizing three criminological theories commonly applied to other forms of substance use: Social Learning Theory, Social Bonding/Control theory, …

Predictors Of Adolescents Attitudes Towards Hepatitis C, Magdalena Sotiroski

School of Psychology and Social Science Presentations

Hepatitis C is referred to as a blood borne virus and transmission is possible when there is blood to bloodcontact. In Australia one person is exposed to hepatitis C every hour of every day. Attempts to increase knowledge and change attitudes towards hepatitis C in the community have been limited, particularly among target groups such as young people. It seems the majority of hepatitis C education and prevention efforts have focused on the provision of information (cognitions) to increase awareness and reduce engagement in risk behaviours (Brown, Perlmutter & McDermott, 2000; Munoz-Plaza, Strauss, Astone, Jarlais & Hagan, 2004). In contrast, …

Adolescent girls construct a developing sense of identity amongst a vast array of contextual influences, including family, school, peer relationships, and set within a broader societal context (Choate, 2007). Negotiating the many nuances, demands and dynamics of all these factors present young girls with developmental stressors. Secondary schools worldwide have an established tradition of providing pastoral care in an attempt to foster individual well being and guide students’ through the challenges of adolescence and beyond, with varying degrees of success (Calvert, 2009). The current study is a qualitative exploration of the experiences of a group of 36 adolescent girls as …

Social Capital In Metropolitan Playgroups : A Qualitative Analysis Of Early Parental Interactions [Presentation], Hebba Gibson

School of Psychology and Social Science Presentations

Parents’ ability to rely on their social contacts to access different types of support is said to reflect their levels of Social Capital (SC). Playgroups are considered a hub for fostering SC that will benefit parents (Powell, 2005). However, empirical evaluations of playgroups that measure their effectiveness using measures of SC are scarce. The present study investigated early parental interactions in playgroups and the ways in which such interactions reflect parents’ levels of SC. Additionally, the study evaluated SC inequalities between parents relative to the strength of their social ties. A qualitative design, using phenomenology was used to understand the …

Conceptualising Female Perpetrated Violence Towards Intimate Male Partners: A Delphi Study Of Expert’S Views, Sarah Moate

School of Psychology and Social Science Presentations

Despite increased acknowledgement that males as well as females can be victims of intimate partner violence, compared to the extensive literature on male perpetrators of intimate partner abuse, the literature on female perpetrated violence towards male partners is exceptionally scarce (Dutton, Nicholls & Spidel, 2005). What is evident from the research that does exist, is that there is a lack of discussion and consensus in regards to the causal explanations specific to this type of female violence. The present study aimed to address this by exploring the ways in which local experts in the field of family and domestic violence …

Working The Companion Animal In The Context Of New Interpersonal Relationships, Steven Remic

School of Psychology and Social Science Presentations

Companion animals are found in the majority of western households. In surveys it has been found that companion animals are often viewed as family members. There is debate in psychological literature on what people mean when they describe companion animals in familial terms, with three theoretical frameworks posited to help explain the pets-as-family phenomena. Attachment theorists suggest that pets meet all four criteria for psychological attachment. Other researchers have suggested that companion animals are positioned within family systems, and are part of the dynamic interplay between human family members. Evolutionary psychologists have suggested that companion animals take advantage of in-built …

Maternal Humanitarian Entrants “Me Time”: The Ways Social Support Works In A Facilitated Playgroup, Annmarie La Rosa

School of Psychology and Social Science Presentations

This study explored how maternal humanitarian entrants (MHE) ascribe meanings to the ways social support works in a facilitated playgroup context. The secondary research question addressed the extent to which accounts of playgroup support could be explained by Bronfenbrenner’s Ecological Systems Theory (BEST). A focus group followed by case study and follow-up interviews provided the women, staff and stakeholders the opportunity to share their narratives. Rich descriptions of their "lived" experience were central to the research purpose. Interpretative phenomenological analysis was employed to validate the ascribed meanings of ways social support manifested in the playgroup. The role of BEST contributed …

An Examination Of The Nonresidential Stepmother Role, Jenine Rocca

School of Psychology and Social Science Presentations

Stepmothers are consistently underrepresented in stepfamily research (Orchard & Solberg, 1999), particularly nonresidential stepmothers (Johnson et al., 2008). The present research investigated how nonresidential stepmothers conceptualise, construct, and evaluate their roles, and to identify factors leading to their role adoption. In-depth interviews were conducted with eight nonresidential stepmothers residing in Perth, Western Australia, who had contact with their stepchildren for fifteen days or less per month. Thematic analysis was used to analyse the data, and results indicated that in terms of their role conceptualisation, the participants perceived their role to have changed, compared their roles to existing roles, and also …

Cognitive And Affective Correlates Of Theory Of Mind As Influenced By Task Modality, April Kane
