River Otter (Lontra Canadensis) Use Of Phragmites Australis And Density Estimation Using Genetic Techniques, Amy R. Williams Jan 2011

River Otter (Lontra Canadensis) Use Of Phragmites Australis And Density Estimation Using Genetic Techniques, Amy R. Williams

School of Natural Resources: Dissertations, Theses, and Student Research

River otters were extirpated in Nebraska in the early 1900’s. In 1986 Nebraska Game and Parks Commission began reintroducing otters. In support of developing an otter management plan, I conducted research on two aspects of otter ecology in Nebraska. First, I examined otter use of habitats dominated by the non–native aquatic plant, Phragmites australis, in the Big Bend reach of the Platte River. Sixteen otters were trapped, radio–tagged, and tracked between 2006 and 2009. I identified 517 den/resting locations, 127 of which were unique locations. I compared den/resting site habitat use to availability to determine if otters were using …

The Recovery Of Cognitive And Social Cognitive Functioning In Response To Social Cognition Interaction Training Administered In Community Settings: A Longitudinal Study, Lena Reddy Jan 2011

The Recovery Of Cognitive And Social Cognitive Functioning In Response To Social Cognition Interaction Training Administered In Community Settings: A Longitudinal Study, Lena Reddy

Department of Psychology: Dissertations, Theses, and Student Research

Psychosocial rehabilitation for persons with Serious Mental Illness (SMI) encompasses recovery of functioning in a broad array of domains, including neurocognitive, social cognitive, interpersonal, occupational, and self-care abilities. There is extensive evidence that improvements in these domains are possible as a result of targeted interventions, and that these improvements may generalize to other areas of daily functioning. The current study explored rehabilitative change over time among adults with SMI that were attending outpatient day centers. Social Cognition and Interaction Training (SCIT), a cognitive-behavioral skills-training modality, was implemented during the time period in which the data was collected. Forty adults participated …

Journal Impact Factor, Scott H. Church Jan 2011

Journal Impact Factor, Scott H. Church

Department of Communication Studies: Dissertations, Theses, and Student Research

In a recent issue of Human Communication Research, Thomas Hugh Feeley notes, “journal impact rankings provide objective data for tenure, promotion, and, possibly, grant review committees on the quality of scholars’ work.” Though the metric is widely regarded as the conventional measure to assess the influence of a journal in both the social and physical sciences, many doubts regarding its effectiveness have been raised. This essay assesses the effectiveness of the Journal Impact Factor (JIF) as a scholarly metric. After first considering the metric's history and developing a working definition of JIF (part one), next I delineate its strengths and …

Mechanisms Of Decreased Cholesterol Absorption Mediated By Phytosterols In The Intestinal Lumen, Andrew W. Brown Jan 2011

Mechanisms Of Decreased Cholesterol Absorption Mediated By Phytosterols In The Intestinal Lumen, Andrew W. Brown

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Phytosterols and their fatty acyl esters have been known for decades to lower LDL cholesterol, making them powerful nutraceuticals in lowering cardiovascular disease risk. The mechanisms by which phytosterols lower cholesterol, though, have been incompletely characterized. Three studies were executed to examine three aspects of cholesterol and phytosterol interactions in the intestinal lumen. In the first study, the ability of pancreatic cholesterol esterase to hydrolyze phytosterol esters was examined. Pancreatic cholesterol esterase hydrolyzed phytosterol esters, but the rate of hydrolysis proved sensitive to the structures of both the sterol and ester components. In the second study, cholesterol micellarization was challenged …

I, An Improved Procedure For Alkene Ozonolysis. Ii, Exploring A New Structural Paradigm For Peroxide Antimalarials., Charles Edward Schiaffo Jan 2011

I, An Improved Procedure For Alkene Ozonolysis. Ii, Exploring A New Structural Paradigm For Peroxide Antimalarials., Charles Edward Schiaffo

Department of Chemistry: Dissertations, Theses, and Student Research

The use of ozone for the transformation of alkenes to carbonyls has been well established. The reaction of ozone with alkenes in this fashion generates either a 1,2,4-trioxolane (ozonide) or a hydroperoxyacetal, either of which must undergo a separate reduction step to provide the desired carbonyl compound. There is considerable interest in being able to perform a reductive ozonolysis to directly provide the carbonyl. Previous reports from the Dussault lab have shown that amine N-oxides are able to perform a reductive ozonolysis. In the course of efforts to expand this reaction to other oxyanions it was realized that water was …

Fabrication And Catalytic Property Of Cerium Oxide Nanomaterials, Keren Jiang Jan 2011

Fabrication And Catalytic Property Of Cerium Oxide Nanomaterials, Keren Jiang

Department of Chemistry: Dissertations, Theses, and Student Research

Cerium oxide, or ceria (CeOx: x = 1.5 to 2), has been widely used as a heterogeneous catalyst. Ceria has several properties make it high catalytic active: the fluctuating valence of cerium, the high oxygen storage capacity and high oxygen mobility in the nonstoichiometric ceria. With the high abundance of cerium on earth crust, ceria is a highly effective alternative of the noble metal catalysts. Research has been focused on designing nanostructured ceria and ceria related materials in recent years. The catalytic activity of ceria can be enhanced by the nanoscale effect which can be applied for various …

Higher Education Professional Pilot Faculty Qualifications: Are The Stakes Rising?, David C. Ison Jan 2011

Higher Education Professional Pilot Faculty Qualifications: Are The Stakes Rising?, David C. Ison

Applied Aerospace Science

"Within the aviation research literature there have been numerous studies that have either included or focused upon the attributes of associated faculty. Although such studies provide compelling data about these individuals, trends or changes in requirements for faculty are not easily identified within the findings. Of particular concern is the fact that credentialization, the escalation of required educational attainment and certification, has been permeating throughout higher education in the United States. It is of interest to see if such pressures are also infiltrating the collegiate aviation environment. Further, data about trends can help future faculty prepare for possible employment, it …

Variation In Tree Mortality And Regeneration Affect Forest Carbon Recovery Following Fuel Treatments And Wildfire, Christopher Hale Carlson Jan 2011

Variation In Tree Mortality And Regeneration Affect Forest Carbon Recovery Following Fuel Treatments And Wildfire, Christopher Hale Carlson

Graduate Student Theses, Dissertations, & Professional Papers

Forest fuel treatments such as thinning and burning have been proposed as tools to stabilize carbon stocks in fire-prone forests in the Western U.S. Although treatments immediately reduce forest carbon storage, losses may be paid back over the long-term if treatment sufficiently reduces future wildfire severity. Less severe wildfire produces fewer direct and indirect carbon emissions, and severely burned stands may be more susceptible to deforestation. Although fire severity and post-fire tree regeneration have been indicated as important influences on long-term carbon dynamics, it remains unclear how natural variability in these processes might affect the ability of fuel treatments to …

Winter Habitat Use By Mule Deer In Idaho And Montana, Sonja M. Smith Jan 2011

Winter Habitat Use By Mule Deer In Idaho And Montana, Sonja M. Smith

Graduate Student Theses, Dissertations, & Professional Papers

Winter survival for species such as Rocky Mountain mule deer (Odocoileus hemionus hemionus) depends on an energy conservation strategy where they use habitats at lower elevations and on south facing slopes with adequate thermal or canopy cover. However, not all mule deer habitats are equivalent in components or weather conditions, which contribute to differences in habitat use patterns and behavior among wintering populations. We examined winter habitat use by mule deer on the East Front of the Rocky Mountains, Montana and Warm Springs and Sink Creek, east-central Idaho to determine how weather and vegetation affect habitat use in different winter …

Waging War On "Unemployables"? Race, Low-Wage Work, And Minimum Wages: The New Evidence, Harry G. Hutchison Jan 2011

Waging War On "Unemployables"? Race, Low-Wage Work, And Minimum Wages: The New Evidence, Harry G. Hutchison

Hofstra Labor & Employment Law Journal

Capturing both popular and academic imaginations, recent literature contributions contest the standard treatment of minimum wage statutes as vehicles that enlarge the economic and social dislocation of vulnerable workers. A persistent strain of the current scholarship dedicated to progressive labor ideology implies that minimum wages or, alternatively, living wage statutes are necessary to preclude the degradation of low-wage workers. The publication of Simon Deakin and Frank Wilkinson’s recent article, Minimum Wage Legislation, constitutes yet another effort to destabilize the neoclassical consensus that emphasizes the adverse employment effects of wage regulation. Prescinding from orthodox economic analysis, Deakin and Wilkinson insist that …

Brain Drain Out Of Hungary And Its Inhibitors, Eliza Plous Jan 2011

Brain Drain Out Of Hungary And Its Inhibitors, Eliza Plous

Capstone Collection

In many Central and Eastern European countries, a poor economic climate at home forces young people to make their careers in the West. Hungary is no exception. After spending time both studying and working in Hungary, the author chose to investigate the phenomenon known as “brain drain”: the large-scale emigration of young, educated individuals from Hungary as they seek higher salaries and more promising career prospects in neighboring Western European countries. This paper offers a comprehensive report on the economics of the brain drain problem, and on the opinions of young Hungarians who are currently seeking employment abroad; it also …

The Role Of Youth In Post-Conflict Reconstruction (The Case Of Liberia), Marit Woods Jan 2011

The Role Of Youth In Post-Conflict Reconstruction (The Case Of Liberia), Marit Woods

Capstone Collection

African youth today no longer want to view themselves as future leaders; instead they want to be viewed as leaders of today who have the ability to shape their own future. Despite the limited opportunities available to youth in the developing world, they strive to become contributors to their communities. Once the world realizes the importance of empowering youth, young Africans will have more opportunities to excel. The purpose of this inquiry is to answer “What opportunities are available for Liberian youth (15-35 years old), and how can these opportunities enhance youth participation in the National Reconstruction Process?” Utilizing qualitative …

Public Policy, Human Instincts, And Economic Growth, Jonathan B. Wight Jan 2011

Public Policy, Human Instincts, And Economic Growth, Jonathan B. Wight

Economics Faculty Publications

Alfred Marshall famously insisted that economics is more like biology than physics. Societies are organic ecologies that evolve and produce organized but unplanned complexity (Hayek 1979). Although no public policy reliably produces economic growth across all ecosystems, a key element unites diverse institutions and policies that do seem to work: they all are reasonably compatible with human instinct. Institutions that build on the basic instinct for self-betterment (as in markets) have a much easier time in achieving success than institutions that oppose it (as in communism). Instincts, like gravity, are a force of nature. Adam Smith theorized, for example, …

Polycystic Diseases In Visceral Organs, Shakila Abdul-Majeed, Surya M. Nauli Jan 2011

Polycystic Diseases In Visceral Organs, Shakila Abdul-Majeed, Surya M. Nauli

Pharmacy Faculty Articles and Research

Primary cilia are nonmotile, microtubule-based, antenna-like organelles projecting from the apical surface of most mammalian cells. Elegant studies have established the importance of ciliary structure and function in signal transduction and the sensory roles of cilia in maintaining healthy cellular state. In particular, dysfunctional cilia have been implicated in a large number of diseases mainly characterized by the presence of fluid-filled cysts in various organs. Aside from polycystic kidney disease (PKD), however, the roles of cilia in polycystic liver disease (PLD), polycystic pancreas disease (PPD), and polycystic ovarian syndrome (PCOS) are still very vague. In addition, although gender and sex …

Pharmacy Faculty Articles and Research

Six classes of coumarin derivatives (i.e. 3-alkyl-4-methylcoumarins, pyranocoumarins, coumarin carboxamides, quaternary ammonium coumarins, 7-aminocoumarins, and 4-aminocoumarins) were synthesized and evaluated for inhibition of cell proliferation of colon adenocarcinoma (HT-29), breast carcinoma (MDA-MB-468 or MCF-7), and human ovarian adenocarcinoma (SK-OV-3) cells. C-3-Alkyl substituted analogs of 4-methylcoumarins and pyranocoumarins, 5 and 6, inhibited the cell proliferation of MDA-MB-468 and SK-OV-3 cells by 53-74%, while 3-decyl substituted pyranocoumarin 10 and triethyl substituted quaternary ammonium coumarin derivative 29 inhibited the cell proliferation of HT-29 and SK-OV-3 cells by 63-72% at a concentration of 50 μM. Among all the compounds studied, C-3 decyl substituted quaternary …

Pharmacy Faculty Articles and Research

In the following respects, tooth enamel is a unique tissue in the mammalian body: (a) it is the most mineralized and hardest tissue in it comprising up to 95 wt% of apatite; (b) its microstructure is dominated by parallel rods composed of bundles of 40 – 60 nm wide apatite crystals with aspect ratios reaching up to 1:10,000 and (c) not only does the protein matrix that gives rise to enamel guides the crystal growth, but it also conducts its own degradation and removal in parallel. Hence, when mimicking the process of amelogenesis in vitro, crystal growth has to …

Pretend Land, Detrachia M. Neely Jan 2011

Pretend Land, Detrachia M. Neely

HIM 1990-2015

The bond between a mother and child is thought to be sacred. It is a phenomenon that society seems to expect as axiomatic based on the single biological fact that a woman carries her child, creating an inseparable bond; even for non-biological mothers, the bond is perceived as one of supreme importance. What happens to the mother and to the child, if this sacred bond is broken? The intent of this thesis was to focus on the perceived bond between mother and child and turn it on its head. As a work of fiction, Pretend Land is a series of …

The Effects Of Attention Deficit/Hyperactivity Disorder On Fixations And Saccades During A Simulated Driving Task, Jessica R. Michaelis

HIM 1990-2015

Individuals who have Attention Deficit/Hyperactivity Disorder (ADHD) experience adverse effects relating to driving; in addition, they experience deficits in scanning ability (Barkely et.al, 1996; Fischer et al., 2007; Munoz et al., 2003; Naja-Raja et al., 2007). The present study examined the effects of ADHD on eye tracking while driving. Ten participants consisting of both ADHD and individuals who do not have ADHD were included in this study. It was hypothesized that individuals who have ADHD will make more saccadic eye movements and thus shorter fixations than individuals who do not have ADHD. Furthermore, it was hypothesized that despite the fact …
