Textual Appropriation In Engineering Master's Theses: A Preliminary Study, Edward J. Eckel

University Libraries Faculty & Staff Publications

In the thesis literature review, an engineering graduate student is expected to place original research in the context of previous work by other researchers. However, for some students, particularly those for whom English is a second language, the literature review may be a mixture of original writing and verbatim source text appropriated without quotations. Such problematic use of source material leaves students vulnerable to an accusation of plagiarism, which carries severe consequences. Is such textual appropriation common in engineering master’s writing? Furthermore, what, if anything, can be concluded when two texts have been found to have textual material in common? …

Influence Of Type 2 Bovine Viral Diarrhea Virus NPro On Enhancement Of Bovine Respiratory Syncytial Virus Replication Mediated By Antagonism Of Host Cell Interferon Type I Responses, Abdulrahman Abdulaziz A. Alkheraif

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Bovine viral diarrhea virus (BVDV) is a member of the genus Pestivirus, Family Flaviviridae. The virus can infect many species of animals of the order Artiodactyla. The BVDV genome encodes an auto protease, N^pro, that degrades interferon regulatory factor-3 (IRF-3) reducing type I interferon (IFN-I) production from host cells. Bovine respiratory syncytial virus (BRSV) is a member of the genus Pneumovirus, Family Paramyxoviridae. Concurrent infection with BVDV and BRSV causes more severe respiratory and enteric disease than infection with either virus alone. Our hypothesis was that N^pro modulates the innate immune responses to BVDV infection …

Gender And Health: A Social Movement’S Agenda For Big Pharma, Margaret Grieco

Wagadu: A Journal of Transnational Women's & Gender Studies

Social movements have an important new campaigning and organizing competence in new information communication technologies. These technologies also enable the members of social movements to readily research the accuracy of information: knowledge becomes globalized and readily accessible. In relation to Big Pharma, women’s social movements and social movements of the medicated intersect, and there is now a substantial challenge to Big Pharma both within developed and developing countries from the terrain of gender and health. This paper documents those challenges and looks towards their consequences in the future both in respect of Big Pharma but also in terms of 'academic' …

Are Biotechnology And Sustainable Agriculture Compatible?, David E. Ervin, Leland L. Glenna, Raymond Adelard Jussaume

Economics Faculty Publications and Presentations

Agricultural biotechnology has been largely opposed by advocates in the sustainable agriculture movement, despite claims by the technology’s proponents that it holds the promise to deliver both production (economic) and environmental benefits, two legs of the sustainability stool. We argue in this paper that participants in this polarized debate are talking past each other because assumptions about biotechnology and sustainability remain simplistic and poorly defined. Genetically engineered (GE) herbicide-resistant and insect-resistant crop varieties are the most visible current forms of agricultural biotechnology, and thus the form of biotechnology that many in the sustainability movement react to. However, these crops represent …

Nordestina Modernity In The Novels Of Freitas, Queiroz, And Lispector, Fernanda Patricia Fuentes Muñoz

CLCWeb: Comparative Literature and Culture

In her article "Nordestina Modernity in the Novels of Freitas, Queiroz, and Lispector" Fernanda Patricia Fuentes Muñoz discusses aspects of the Nordeste — the northeastern region of Brazil — in Emília de Freitas's A Rainha do Ignoto (1899), Rachel de Queiroz's O Quinze (1930), and Clarice Lispector's A Hora da Estrela (1977; The Hour of the Star, 1992, Trans. Giovanni Pontiero). The region has traditionally been seen as located on the margins of modernity and as a site of underdevelopment in the Brazilian imaginary in opposition to the affluent Southeastern region. The construction of this binary opposition suggests a model …

Danticat's The Dew Breaker, Haiti, And Symbolic Migration, Jennifer E. Henton

CLCWeb: Comparative Literature and Culture

In her article "Danticat's The Dew Breaker, Haiti, and Symbolic Migration" Jennifer E. Henton analyzes Edwidge Danticat's novel with Lacanian thought. It is assumed frequently that literatures of the non-West "arrive" when they move from political and didactic traditions to the "aesthetic" and experimental models that delve into the terrain of the psyche. In The Dew Breaker, the Haitian family's move to the U.S., executed self consciously, indicates loss in a different sense than lack. In the case of Denticat's novel, loss or lack represent not a source of anxiety that evokes matters read in a psychoanalytical framework; instead, Henton …

Haitian Zombie, Myth, And Modern Identity, Kette Thomas

CLCWeb: Comparative Literature and Culture

In her article "Haitian Zombie, Myth, and Modern Identity" Kette Thomas analyzes texts by Zora Neale Hurston, Alfred Metraux, and Wade Davis. In these narratives we are re-introduced to the zombie not as a metaphor for lost consciousness, but, rather, as a common system that replaces personal subjectivity with an influence alien to our natural development. The discourse on subjectivity has become a central focus in the modern era but attention to fiction in "third world" cultures is neglected because they are studied almost exclusively through historical, political, sociological, or anthropological lenses or because their collective identities leads scholars to …

Architecture Theses and Projects

The goal of the project is to create a building that can be as active as possible throughout the day and evening. This can be done by finding a variety of users to occupy the building for different times of the day. In addition, creating multipurpose spaces will allow the building to stay smaller in size; a space in the building can take on multiple functions. Bringing in the entire community to this building is what will make the building successful. The building will be designed with the entire community in mind; young, middle-age, and elderly, not just a specific …

Research Of Glycosylated Granulocyte Colony-Stimulating Factor On Mobilizing Cell Regeneration Of Bone Marrow Stem Cells And Repairing Injured Myocardium, Yuan Ma, Ming Luo

Saudi Medical Journal

OBJECTIVE: To compare the differences between glycosylated and non-glycosylated granulocyte colony-stimulating factor (G-CSF) on mobilizing cell regeneration of bone marrow stem cells and repairing injured myocardium. METHODS: In the acute myocardial ischemia model, 40 Sprague-Dawley rats (8 weeks old, weight 200-250 g) were successfully established with isoproteronol (ISO) and randomly and evenly divided into 4 groups: Group G (injected with glycosylated G-CSF), Group N (non-glycosylated G-CSF), Group C ([control] normal saline for 7 days), and Group M (model). At day 5, all rats were labeled with bromodeoxyuridine (BrdU). At day 28, the proportion of CD34+ cells, myocardial BrdU immunohistochemical stain, …

Protected Areas Reduced Poverty In Costa Rica And Thailand, Kwaw S. Andam, Paul J. Ferraro, Katharine R. E. Sims, Andrew Healy, Margaret B. Holland

Economics Faculty Works

As global efforts to protect ecosystems expand, the socioeconomic impact of protected areas on neighboring human communities continues to be a source of intense debate. The debate persists because previous studies do not directly measure socioeconomic outcomes and do not use appropriate comparison groups to account for potential confounders. We illustrate an approach using comprehensive national datasets and quasi-experimental matching methods. We estimate impacts of protected area systems on poverty in Costa Rica and Thailand and find that although communities near protected areas are indeed substantially poorer than national averages, an analysis based on comparison with appropriate controls does not …

Comparison Of Two Potential Streamgage Locations On Scott Creek At Swanton Pacific Ranch, California, Matthew C. Scrudato

Master's Theses

Two locations on Scott Creek, located 12 miles north of Santa Cruz California, are being considered for the installation of a streamgage to measure discharge. Each location offers unique considerations and challenges in gage construction and discharge measurement capabilities. A detailed flood frequency analysis was completed using a direct watershed comparison, direct equations developed by Waananen and Crippen, a Log Pearson Type III Frequency Distribution, a regional analysis, and two-station comparisons. Final results indicate a 100-year recurrence interval of 6,310 ft3/s at the Upper Scott Creek location and 6,520 ft3/s at the lower location. A detailed indirect measurement revealed that …

Thrombin And Exercise Similarly Influence Expression Of Cell Cycle Genes In Cultured Putative Endothelial Progenitor Cells, Michael M. Lockard, Sarah Witkowski, Nathan T. Jenkins, Espen E. Spangenburg, Thomas O. Obisesan, James M. Hagberg

Exercise and Sport Studies: Faculty Publications

Acute exercise and exercise training may influence putative endothelial progenitor cell (EPC) number and colony forming units (CFU-ECs), although the mechanisms remain unclear. This study examined the effects of in vitro thrombin supplementation and acute exercise on CFU-EC gene expression, associated with cellular proliferation and differentiation. The effect of habitual physical activity was evaluated through analysis of EPCs from chronically high- and low-active men. Participants were healthy high- and low-active men (n = 23), aged 55-80 yr. Circulating CD34+/VEGFR2+ number, CFU-ECs, plasma prothrombin fragment (F1+2), and thrombin-antithrombin III were measured at rest and after 30 min of exercise. Gene expression …

Real-Time Visualizations Of Ocean Data Collected By The Norus Glider, Daniel M. Medina

Master's Theses

Scientific visualization computer applications generate visual representations of large and complex sets of science data. These types of applications allow scientists to gain greater knowledge and insight into their data. For example, the visualization of environmental data is of particular interest to biologists when trying to understand how complex variables interact. Modern robotics and sensors have expanded the ability to collect environmental data, thus, the size and variety of these data-sets have likewise grown. Oftentimes, the collected data are deposited into files and databases where they sit in their separate and unique formats. Without easy to use visualization tools, it …

A Comprehensive Index For Assessing Environmental Stress In Animals, Terry L. Mader, Leslie J. Johnson, John B. Gaghan Dr

Nebraska Cooperative Extension: Faculty and Staff Publications

Numerous models and indices exist that attempt to characterize the effect of environmental factors on the comfort of animals and humans. Heat and cold indices have been utilized to adjust ambient temperature (Ta) for the effects of relative humidity (RH) or wind speed (WS) or both for the purposes of obtaining a “feels-like” or apparent temperature. However, no model has been found that incorporates adjustments for RH, WS, and radiation (RAD) over conditions that encompass hot and cold environmental conditions. The objective of this study was to develop a comprehensive climate index (CCI) that has application under a wide range …

The Human Oral Microbiome Database: A Web-Accessible Resource For Investigating Oral Microbe Taxonomic And Genomic Information, Tsute Chen, Wen-Han Yu, Jacques Izard, Oxana V. Baranova, Abirami Lakshmanan, Floyd E. Dewhirst

Department of Food Science and Technology: Faculty Publications

The human oral microbiome is the most studied human microflora, but 53% of the species have not yet been validly named and 35% remain uncultivated. The uncultivated taxa are known primarily from 16S rRNA sequence information. Sequence information tied solely to obscure isolate or clone numbers, and usually lacking accurate phylogenetic placement, is a major impediment to working with human oral microbiome data. The goal of creating the Human Oral Microbiome Database (HOMD) is to provide the scientific community with a body site-specific comprehensive database for the more than 600 prokaryote species that are present in the human oral cavity …

Good Agricultural Practices For Food Safety Of Fresh Produce, Laurie Hodges

Department of Agronomy and Horticulture: Faculty Publications

What are the guiding principles of food safety for fresh produce?

• Once contaminated, removing or killing pathogens on produce is very difficult.

• Preventing microbial contamination at all steps, from production to distribution, is strongly favored over treatments to eliminate contamination that may have occurred.

• Document the implementation of prevention programs, and educate workers at all levels of the agricultural and packing environments on food safety.

Key Signatures of a Credible Food Safety Program

The following is a condensed checklist of practices and conditions that reduce the potential for fresh produce to be exposed to pathogenic microbes. Review …

Multi-Robot System Control Architecture (Mrsca) For Agricultural Production, Santosh Pitla, Joe D. Luck, Scott A. Shearer

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Coordinating multiple autonomous robots for achieving an assigned collective task presents a complex engineering challenge. In this paper multi robot system control architecture (MRSCA) for the coordination of multiple agricultural robots is developed. The two important aspects of MRSCA; coordination strategy and inter-robot communication were discussed with typical agricultural tasks as examples. Classification of MRS into homogeneous and heterogeneous robots was done to identify appropriate form of cooperative behavior and inter-robot communication. The framework developed, proposes that inter-robot communication is not always required for a MRS. Three types of cooperative behaviors; No-cooperation, modest cooperation and absolute cooperation for a MRS …

Pneumatic Control Of A Variable Orifice Nozzle, Joe D. Luck, Michael P. Sama, Santosh Pitla, Scott A. Shearer

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

A variable-orifice nozzle with droplet optimization was recently developed and introduced for use on agricultural sprayers. The VariTarget (VT) nozzle reacts to changes in the system flow rate via a metering assembly that is controlled by a diaphragm and spring. As the liquid pressure changes, the VT metering assembly attempts to control the flow rate and spray pattern exiting the nozzle. The goal of this study was to replace the spring controlled “reactive” system with a pneumatically controlled metering assembly. The proposed system would allow for the metering assembly to adjust the flow rate and spray pattern exiting the nozzle …

Geophysical Mapping Of Preferential Flow Paths Across Multiple Floodplains, Ronald B. Miller, Derek M. Heeren, Garey A. Fox, Daniel E. Storm, Todd Halihan, Aaron R. Mittelstet

Department of Agricultural and Biological Systems Engineering: Faculty Publications

In the Ozark ecoregion of Oklahoma, Arkansas and Missouri, the erosion of carbonate bedrock (primarily limestone) by slightly acidic water has left a residuum of chert gravel, producing gravel-bed streams and floodplains generally consisting of coarse chert gravel overlain by a mantle (1 to 300 cm) of gravelly loam or silt loam. Previous research has documented the occurrence of preferential flow paths (PFP) in an alluvial floodplain hypothesized to be a buried gravel bar. Field experiments have shown that the PFP affected alluvial groundwater flow in the floodplain and that water flow in the PFP was transmitted at rates that …
