Community Correlates Of Rural Youth Violence, D. Wayne Osgood, Jeff M. Chambers
Community Correlates Of Rural Youth Violence, D. Wayne Osgood, Jeff M. Chambers
Center on Children, Families, and the Law: Faculty Publications
Rates of crime and delinquency vary widely across communities, and research going back many decades provides a good understanding of the nature, correlates, and probable causes of these community differences. Unfortunately, previous studies have been limited in an important way. Virtually all studies of communities and crime are based on large urban areas, almost totally excluding nonmetropolitan areas—that is, rural areas and smaller cities and towns. The findings in this Bulletin help to fill some gaps in the research by examining variations in rates of juvenile violence across nonmetropolitan communities in Florida, Georgia, Nebraska, and South Carolina.

Fire, Soil, Native Species And Control Of Phalaris Arundinacea In A Wetland Recovery Project., Richard Douglas Foster
Fire, Soil, Native Species And Control Of Phalaris Arundinacea In A Wetland Recovery Project., Richard Douglas Foster
Electronic Theses and Dissertations
Southern Appalachian Phalaris arundinacea control was investigated by: 1) correlating cover and species richness with soil characteristics across transects; 2) burning and herbicide use to determine conditions facilitating native plant establishment; and 3) hemi-parasitic Pedicularis lanceolata tested as a biological control.
Phalaris cover was correlated with subsoil consolidation; areas without Phalaris had consolidated subsoil while Phalaris at >50% cover established on loose soil. Phalaris cover inhibited species richness (r2=0.78). No soil characteristic predicted species richness.
Herbicide reduced Phalaris cover and aerial biomass by 23% and 63% respectively, compared to controls. Burning was ineffective. Two summers after herbicide Phalaris …
Protection Of Pifithrin-Α And Melatonin Against Doxorubicin-Induced Cardiotoxicity., Xuwan Liu
Protection Of Pifithrin-Α And Melatonin Against Doxorubicin-Induced Cardiotoxicity., Xuwan Liu
Electronic Theses and Dissertations
The current studies were designed to explore the protective effects of pifithrin-α and melatonin against doxorubicin-induced cardiotoxicity. Doxorubicin was injected at a dose of 22.5 mg/kg (i.p.) in mice to induce cardiotoxic effects. Meanwhile, doxorubicin caused a significant increase of cardiac cell apoptosis following injection (14.2 ± 1.1% for doxorubicin-5 d vs. 1.8 ± 0.12% for control, P < 0.01). Ribonuclease protection assays and Western blot analyses revealed that doxorubicin upregulated the p53-dependent genes Bax, BclxL, and MDM2 at least 2-fold. p53 was phosphorylated at Ser 15 in mouse hearts 1 h following doxorubicin injection, and p38 and ERK1/2 MAPKs mediated the phosphorylation of p53. In addition, caspases-3 and -9 were activated 24 h after doxorubicin injection. A p53 inhibitor, pifithrin-α, inhibited doxorubicin-induced apoptosis when administered at a dose of 2.2 mg/kg. Pifithrin-α abolished p53 transactivation activity, but did not influence doxorubicin-induced phosphorylation at Ser 15. By effectively inhibiting the expression of p53-dependent genes, pifithrin-α blocked doxorubicin-induced activation of caspases-3 and -9, thereby preventing cardiac apoptosis. In addition, pifithrin-α attenuated doxorubicin-induced structural and functional damages, without diminishing its anti-tumor efficacy on p53-null PC-3 cancer cells. The protective effects of melatonin and its metabolite 6-hydroxymelatonin on doxorubicin-induced cardiac dysfunction were evaluated in an isolated perfused mouse hearts and in vivo doxorubicin-treated mice. While perfusion of mouse hearts with 5 μM doxorubicin for 60 min resulted in a 50% suppression of HRxLVDP and a 50% reduction of coronary flow, pre-exposure of hearts to 1 μM melatonin or 6-hydroxymelatonin eased the cardiac …

Single Nucleotide Polymorphism (Snp) Analysis Of Tumor Necrosis Factor (Tnf)-Α In Pediatric Autoimmune Neuropsychiatric Disorders Associated With Streptococcal Infections (Pandas) Subjects, Corinna Wilhelmina Vonniederhausern
Undergraduate Honors Capstone Projects
In an ongoing research project, the Center for Persons with Disabilities at Utah State University, in collaboration with Dr. Susan E. Swedo at the National Institute of Mental Health, is evaluating genetic factors affecting the development of PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections). PANDAS is manifested in a group of prepubertal children who develop obsessive-compulsive disorder (OCD) following infection with Group A beta-hemolytic Streptococcal (GABHS) bacteria. We are assessing single nucleotide polymorphisms (SNPs) in the promoter region of tumor necrosis factor (TNF)-α and other cytokines known to be important in autoimmune diseases.
Status Of Migratory Shorebirds At An Inland Stopover Site In The Northern Plains Prairie Pothole Region, Corinne A. Carey
Status Of Migratory Shorebirds At An Inland Stopover Site In The Northern Plains Prairie Pothole Region, Corinne A. Carey
Theses and Dissertations
Teeming with macroinvertebrates, hundreds of tiny wetlands dotting the prairie region of North Dakota provide nutrient rich foraging sites for large numbers of migratory shorebirds. Because these wetlands are typically small, dispersed and ephemeral, documentation of shorebird numbers in the region has been a difficult task. Large variation in survey data has resulted in an overall underestimate in the value of this shorebird habitat.
To assess the status of local migratory shorebirds, I conducted weekly shorebird surveys at eight sites within Kelly's Slough National Wildlife Refuge. These surveys included a bi-weekly inventory of resident invertebrates, a well established prey base …

Ifeminism, Ashlie Warnick
Ifeminism, Ashlie Warnick
Michigan Law Review
Laws should be judged not by their words or intentions, but by their effects and consequences. When government enacts laws designed to benefit one group, society should judge those laws first by examining whether they have, in practice, provided a net benefit to the law's intended beneficiaries. Next, any such benefit must be weighed against the costs imposed on the rest of society. If the benefits outweigh the costs, this is a socially efficient law. Government should repeal a law when the costs it imposes outweigh its benefits. When laws do not provide a net benefit to the group they …
The New Leviathan, Dennis Patterson
The New Leviathan, Dennis Patterson
Michigan Law Review
Reputation in any field is an elusive phenomenon: part notoriety, part honor, part fame, part critical assessment. Even in legal scholarship it has an uneven, unpredictable quality. It is hard to imagine a book by a law professor that has had more immediate impact on world leaders than Philip Bobbitt's The Shield of Achilles. Much of the national-security strategy devised by the U.S. administration after the September 11 attacks expresses ideas Bobbitt conceived long before; and from a different point on the political spectrum is the Archbishop of Canterbury, whose televised nationwide address in January explicitly took the book as …
Consuming Government, Richard Schragger
Consuming Government, Richard Schragger
Michigan Law Review
In his ambitious new book, William Fischel, a Professor of Economics at Dartmouth College, gives us a new political animal: "The Homevoter." The homevoter is simply a homeowner who votes (p. ix). According to Fischel, she is the key to understanding the political economy of American local government. By implication, she is the key to understanding state and national government as well. Homeowners warrant special attention because "residents who own their own homes have a stake in the outcome of local politics that make them especially attentive to the public policies of local government" (p. ix). That is because local …
Toward A More Communitarian Future? Fukuyama As The Fundamentalist Secular Humanist, June Carbone
Toward A More Communitarian Future? Fukuyama As The Fundamentalist Secular Humanist, June Carbone
Michigan Law Review
With The End of History and the Last Man, Francis Fukuyama established himself as the prophet of liberal democracy and free markets, heralding their triumph as the only form of governance capable of commanding legitimacy. Asked to reflect on his predictions a decade later, Fukuyama concluded that the greatest threat to liberalism comes from biotechnology because it alone has the potential to remake the human nature that liberal democracy was designed to serve. Fukuyama makes a compelling case that biotechnology may produce developments that should concern us; he is ironically less persuasive in articulating a liberal-democratic framework for governing the …
The Past, Present, And Future Of Bankruptcy Law In America, Todd J. Zywicki
The Past, Present, And Future Of Bankruptcy Law In America, Todd J. Zywicki
Michigan Law Review
As this Review was being written, Congress once again failed to pass the bipartisan bankruptcy-reform bill, although many expect it to be enacted at some point in the near future. At the same time, WorldCom, Enron, Global Crossing, and their ignominous peers continue to set records for the size, expense, and public attention drawn to business bankruptcy. For the first time, consumer bankruptcies surpassed the 1.5 million per year mark, continuing an irresistible upward trend. Meanwhile, law firms announce layoffs and salary freezes in most departments, and bankruptcy professionals prosper amidst the despair, billing $1 million per day on the …
The Unruliness Of Rules, Peter A. Alces
The Unruliness Of Rules, Peter A. Alces
Michigan Law Review
Analytical jurisprudence depends on a posited relation between rules and morality. Before we may answer persistent and important questions of legal theory - indeed, before we can even know what those questions are - we must understand not just the operation of rules but their operation in relation to morality. Once that relationship is formulated, we may then come to terms with the likes of inductive reasoning in Law, the role of precedent, and the fit, such as it is, between Natural Law and Positivism as well as even the coincidence (or lack thereof) between inclusive and exclusive positivism. That …
Meaning's Edge, Love's Priority, Patrick Mckinley Brennan
Meaning's Edge, Love's Priority, Patrick Mckinley Brennan
Michigan Law Review
The story is told of an American wending his way through the British Museum. Reaching the Rosetta Stone, he reached right over the railing, touched the scarred slab, and lamented: "It doesn't feel meaningful." Whereupon an old Briton was heard to mumble: "The poor American's got this old thing confused with the Blarney Stone." A bully presses his case, but meaning is much more modest. Powerless to insist upon itself, meaning lies in wait of discovery. What distinguishes the Rosetta Stone from other rocks of the same kind and size is that it was someone's - or rather a group's …

Biomedical Engineering Faculty Research and Publications
Hyperglycemia is associated with generation of reactive oxygen species (ROS), and this action may contribute to accelerated atherogenesis. We tested the hypothesis that hyperglycemia produces alterations in left anterior descending coronary artery (LAD) wall shear stress concomitant with endothelial dysfunction and ROS production in dogs (n = 12) instrumented for measurement of LAD blood flow, velocity, and diameter. Dogs were randomly assigned to receive vehicle (0.9% saline) or the superoxide dismutase mimetic 4- hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl (tempol) and were administered intravenous infusions of d-glucose to achieve target blood glucose concentrations of 350 and 600 mg/dl (moderate and severe hyperglycemia, respectively). Endothelial …
Adolescent Peer Perceptions Reflected In The Yearbooks Of Mormon Homosexual And Heterosexual Men, David C. Pruden
Adolescent Peer Perceptions Reflected In The Yearbooks Of Mormon Homosexual And Heterosexual Men, David C. Pruden
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study explored the peer perceptions of adolescent heterosexual males and their homosexual counterparts who had not disclosed their feelings of erotic same-sex attraction to their classmates. The study focused on members of The Church of Jesus Christ of Latter-day Saints, a conservative Christian denomination with clear doctrinal prohibitions against homosexual behavior. The handwritten messages from peers found in the senior high school yearbooks of 30 heterosexual and 30 same-sex attracted adolescent men were content analyzed to examine similarities and differences in the themes that emerged from the data.
The results indicated that there is a difference in the kind …

Social Stratification And Health In Dynastic Egypt: The Differential Effect Of Disease Among The Elite And Working Classes, Jerilyn Hansen
Social Stratification And Health In Dynastic Egypt: The Differential Effect Of Disease Among The Elite And Working Classes, Jerilyn Hansen
Undergraduate Honors Capstone Projects
Social stratification in Dynastic Egypt between the elite and working class is suspected to have created differential health conditions for these two social classes. It is hypothesized that due to differing living conditions, resulting in varying levels of exposure to infectious pathogens, workloads, and quality of diet, the elite and working class will have dissimilar health conditions. Specifically, it is expected that the working class of Dynastic Egypt suffered ill health more often, and more severely, than the elite. The health conditions of the elite and working class were measured by the prevalence of the density-dependent disease tuberculosis, the workload-related …
Vitamin K As A Prophylaxis In The Infant, Michelle Whipple
Vitamin K As A Prophylaxis In The Infant, Michelle Whipple
Undergraduate Honors Capstone Projects
Since the mid-1960's, all infants in the US have received intramuscular vitamin K (IMVK) as a prophylactic measure against hemorrhagic disease of the newborn (HDN). Because the human race has obviously survived for so many years without this medical intervention, there is some question concerning the universal necessity of this practice.
Infants are born with comparatively low levels of vitamin K, a compound vital for the carboxylation of serum clotting factors. In the absence of adequately carboxylated clotting proteins, infants are at risk for developing HDN. This condition can cause severe complications, including mental retardation and death. IMVK significantly reduces …

The Garr Family Saga The Connecting Power Of Oral Narrative, Margaret Garr Jaggi
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
When I was a child, my mother often told me a "true" story about a beautiful Shoshone maiden who married a handsome American cowboy. The setting was the 1850s in the fertile valley of Cache County, Utah. The man's name was John Turner Garr and the woman was called Susie. This young couple was my paternal great-great grandparents. Together they lived a life that defied their disparate cultures. I envisioned them, young, wild, and free; he, dressed in buckskin leggings, riding among the Shoshone men; she, in soft doeskin supporting a papoose on her back. The idyllic life of my …
Rapid Detection Of Listeria Monocytogenes, Wim Lippens
Rapid Detection Of Listeria Monocytogenes, Wim Lippens
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Listeria monocytogenes is a foodbome pathogen that can cause severe illness and even death. It is found in dairy and meat products. The focus is on rapid detection since conventional methods are time consuming (4-5 days). Pre-enrichment steps, as part of those methods, are time consuming. Our objective was to develop a detection system without a pre-enrichment step, giving a final result within 2 to 4 h.
In the concept of "the need for speed," a detection system with an antibody-based capture technique, followed by polymerase chain reaction (PCR), was developed. Glass beads coated with a Listeria polyclonal antibody were …
An Ecological/Life History Comparison Of Two Whitefish Species In Bear Lake, Utah/Idaho, Brett W. Thompson
An Ecological/Life History Comparison Of Two Whitefish Species In Bear Lake, Utah/Idaho, Brett W. Thompson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Ecological traits of the endemic Bear Lake whitefish Prosoopium abyssicola and the Bonneville whitefish prosopium silonotus were investigated. Spatial distributions indicated distinctive differences in depth contour preference. Catch per unit effort data indicated that Bonneville whitefish prefer shallow depths and warmer water temperatures, whereas Bear Lake whitefish prefer deep, cold water.
Diet differences between the two species were large. Differences in both age distribution and growth rate patterns were also observed. The Bonneville whitefish population was predominantly composed of juvenile age classes. Very large adults reached ages of 12-14 years. Bear Lake whitefish exhibited a different population structure with few …

Assessing The Effects Of Myxobolus Cerebralis And Other Environmental Factors On The Dynamics, Abundance, And Distribution Of Trout Populations In The Logan River, Utah, Ernesto A. De La Hoz Franco
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The presence of nonnative trout and the recent introduction of Myxobolus cerebralis in the Logan River drainage pose a threat to the native Bonneville cutthroat trout population (Oncorhynchus clarki Utah). The variability in the response of susceptible trout populations to M. cerebralis, causing agent of whirling disease, suggests that environmental factors may influence the effects of the parasite in infected environments. I investigated the relationship between temperature, discharge, substrate size, nutrient concentration (nitrogen and phosphorus), periphyton (chlorophyll a), and the relative abundance of Tubifex tubifex to the distribution, and prevalence of M. cerebralis in wild salmonid populations and …

Foraging Behavior And Habitat Use Patterns Of Brown Bears (Ursus Arctos) In Relation To Human Activity And Salmon Abundance On A Coastal Alaskan Salmon Stream, Anthony P. Crupi Jr.
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Over the past decade, demand for recreation has increased as part of Alaska's doubling growth in tourism. Along the Chilkoot River, near Haines, fishing and bear viewing have become increasingly popular. I investigated the ecological and behavioral interactions there between brown bears, salmon, and humans between 2000 and 2002. My objectives were to: (1) determine if specific human activities differentially influenced bear activity and foraging behavior, (2) identify temporal and spatial habitat use patterns, (3) evaluate brown bear response to natural and human disturbances and quantify related flight distances, (4) investigate changes in bear foraging behaviors in response to prey …
Modeling Habitat Quality For American Martens In Western Newfoundland, Canada, William A. Adair
Modeling Habitat Quality For American Martens In Western Newfoundland, Canada, William A. Adair
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The "Den Mother" marten habitat quality models were created to provide insight into American marten habitat selection behavior and to promote the recovery of the Newfoundland marten (Martes americana atrata) population. Although these objectives are typical of most wildlife habitat modeling projects, the marten's idiosyncratic habitat ecology and apparently intractable conflicts associated with timber harvesting motivated a unique, process-oriented approach to appraising landscapes. The Den Mother models used optimal decision-making principles to synthesize critical resources (den sites and foraging opportunities) and constraints (adverse thermal situations and exposure to predations) into a single hierarchical framework. The resulting spatially explicit, …
Determining The Factors That Control Respiration And Carbon Use Efficiency In Crop Plants, Jonathan M. Frantz
Determining The Factors That Control Respiration And Carbon Use Efficiency In Crop Plants, Jonathan M. Frantz
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In the literature on plant respiration, there are two viewpoints concerning the source of respiratory control: supply (photosynthate availability) or demand (temperature dependent) limitations. While different studies indicate the primary dependency for respiration is either the supply or demand side, the two paradigms cannot both be true. The relative importance of each paradigm may depend on a number of factors including period of time during which respiration is measured, phase of plant development, environmental conditions, and species.
Studies were performed using continuous CO2 gas-exchange instrumentation to monitor short- and long-term changes in whole canopies of lettuce, tomato, soybean, and …
