Putting A Face On Hunger: A Community-Academic Research Project, Nancy Coffey, Mary K. Canales, Emily Moore, Melissa Gullickson, Brenda Kaczmarski

Journal of Extension

Food insecurity is a growing concern for Eau Claire County residents in Western Wisconsin. A community-academic partnership studied food insecurity through the voices of families struggling to access food and institutions that assist with hunger related problems. Data were collected through focus groups held in urban and rural parts of the county. Participants reported that food insecurity affected all aspects of daily life, increasing stress and reducing coping abilities. Results indicate that when Extension and campus-based staff partner with community groups, they can increase community awareness of and find innovative solutions to pressing community needs, such as food insecurity.

Caepidr: A Computational Approach To Efficient Peptide Influenced Drug Repurposing, Thomas Francis Long

Boise State University Theses and Dissertations

Since the discovery of the molecular basis of disease, numerous studies have reported a correlation between the activity of specific protein receptors the progression of disease. As a result, drug development has become dependent on the study of protein receptor activities. The relative inexpense of computing hardware has made computational methods an important supplementary tool for receptor modeling. This work details an open source software tool that is capable of both efficiently screening large peptide mutant libraries and enabling 3D conformer-based searches over local molecular databases.

A Computational Approach to Efficient Peptide Influenced Drug Repurposing (CAEPIDR) has been developed to …

Potential For Timing High-Energy Marine Inundation Events In The Recent Geological Past Through Age-Dating Of Reef Boulders In Fiji, James P. Terry, Samuel Etienne

All Works

© 2014, Terry and Etienne; licensee Springer. Transported coastal boulders have increasingly come to represent a valuable element of investigations within the broader framework of multi-proxy approaches applied to coastal hazard studies. Through a case study on Taveuni Island in Fiji, this paper outlines some approaches and hindrances to effective timing of prehistorical high-energy marine inundation events (storms and tsunamis) on tropical coastlines from the evidence of reef-platform carbonate boulders. Various sources of errors are outlined that investigators must consider when attempting to use carbonate boulder ages as a surrogate for timing past events. On Taveuni, uranium : thorium dates …

Gender Differences In Response To Contingent Rewards: Evidence From A Natural Experiment Of Junior Tennis, Nejat Anbarci, K. Peren Arin, Jungmin Lee

All Works

© 2014 Elsevier Inc. We investigate gender differences in responding to contingent rewards by exploiting a natural experiment in junior tennis tournaments in Florida where the ranking point system was revised to induce more players to play doubles. The new point system increased the points earned from wins in singles matches significantly if the two thirds or more of players in their sex/age group chose to play doubles. We examine three types of potential responses to the new system: (1) a 'positive' response of playing doubles more by singles winners, (2) a 'subversive' response of playing doubles less by singles …

Blogs, Books, & Breadcrumbs: A Case Study Of Transmedial Fairy Tales, Kristy Gilbert Stewart

Theses and Dissertations

Understanding transmedial storytelling is particularly important to fairy-tale studies. Monomedial views have long been unable to account for all of fairy tale tradition. Although the form originated in oral culture, it has long been a liminal, hybrid form that retains aspects of orality even while its principal mode of transference for some time has been something other than face-to-face communication. Transformations and adaptations across different media and contexts has resulted in a system of fairy-tale tradition that is massively intertextual and transmedial. No one medium can claim primary control over the fairy-tale tradition. Throughout time, oral tellings have inspired literary …

Microvascular Function In Metabolically Healthy Groups Differing In Bmi And Waist Circumference, Nathan R. Earl

Theses and Dissertations

BACKGROUND: Microvascular dysfunction (MD: impaired performance of blood flow, tissue perfusion, blood pressure, etc.) is one of the earliest stages in the progression of various chronic diseases. OBJECTIVE: The aim of this study was to determine if a difference in microvascular function existed between two metabolically healthy groups that differed in BMI and waist circumference. DESIGN: This study employed a causal comparative design, with two groups: I) normal weight (n =14, BMI 28 kg/m2). METHODS: Microvascular function was assessed by measuring skin blood flow (SkBF) using laser Doppler flowmetry during postocclusive reactive hyperemia (PORH). The area under the SkBF time …

A Variable-Stiffness Compliant Mechanism For Stiffness-Controlled Haptic Interfaces, Jeffrey C. Hawks

Theses and Dissertations

In this research a variable-stiffness compliant mechanism was developed to generate variable force-displacement profiles at the mechanisms coupler point. The mechanism is based on a compliant Roberts straight-line mechanism, and the stiffness is varied by changing the effective length of the compliant links with an actuated slider. The variable-stiffness mechanism was used in a one-degree-of-freedom haptic interface to demonstrate the effectiveness of varying the stiffness of a compliant mechanism. Unlike traditional haptic interfaces, in which the force is controlled using motors and rigid links, the haptic interface developed in this work displays haptic stiffness via the variable-stiffness compliant mechanism. The …

Studies Of Phou In Escherichia Coli: Metal Binding, Dimerization,Protein/Protein Interactions, And A Signaling Complex Model, Stewart G. Gardner

Theses and Dissertations

Phosphate is an essential nutrient for all forms of life. Escherichia coli has a PhoR/PhoB two component regulatory system that controls the expression of various genes whose products allow the cell to thrive in low phosphate environments. The signaling mechanism of the PhoR/PhoB system has been studied and the phosphorylation cascade that controls gene expression is well understood. What is still unknown is how PhoR senses the phosphate level of the environment. The PstS, PstC, PstA, PstB, and PhoU proteins play a role in this signal sensing. This work confirms the hypothesis that the PstSCAB complex senses the environmental phosphate …

A Randomized Controlled Trial To Study The Effects Of Breakfast On Energy Intake, Physical Activity, And Body Fat In Women, Gabrielle Marie Lecheminant

Theses and Dissertations

PURPOSE: The purpose of this study was to determine the effects of eating breakfast on energy intake, physical activity, body weight, and body fat in women who were nonhabitual breakfast eaters over a one-month period. METHODS: We tested 49 premenopausal, nonhabitual breakfast-eating women to compare the effects of eating breakfast versus not eating breakfast. Each participant was randomized to one of two conditions: breakfast or no breakfast. Breakfast eaters were required to eat within an hour and a half of awakening and had to be finished eating their breakfast meal by 8:30 A.M. Non-breakfast eaters were defined as not consuming …

Cost Effectiveness Of Treating Generalized Anxiety Disorder In Adolescence: A Comparison By Provider Type And Therapy Modality, Kathryn Evelyn Reynolds

Theses and Dissertations

Generalized anxiety disorder (GAD) is frequently found in primary care settings and is highly prevalent among adolescents. The purpose of this study was to examine the cost effectiveness by provider type and therapy modality in treating adolescents (ages 13-17) with a GAD diagnosis (DSM-IV 300.02). A national insurance company in the United States provided outpatient and unidentifiable data for adolescent GAD cases (n = 2,932). These cases were used to analyze the cost effectiveness, total cost, treatment length, dropout, and readmission rates for the treatment of adolescents with GAD. Descriptive statistics signify that the mean cost of treatment for GAD …

Alcohol Modulation Of Dopamine Release, Nathan Dan Schilaty

Theses and Dissertations

The mesolimbic dopamine (DA) system projects from the ventral tegmental area (VTA) to structures associated with the limbic system, primarily the nucleus accumbens (NAc). This system has been implicated in the rewarding effects of drugs of abuse. Many drugs of abuse act in the VTA, the NAc, or both. Dopamine neurons in the VTA that project to the NAc, and the GABA neurons that inhibit DA neurons locally in the VTA or project to the NAc, play an important role in mediating addiction to various drugs of abuse, in particular alcohol. There is a growing body of evidence of co-dependence …

A Competency Model For Catering And Event Professionals Using A Modified Delphi Technique, Donnell G. Bayot

UNLV Theses, Dissertations, Professional Papers, and Capstones

As the market for face-to-face meetings and events has grown to one of the largest private sector industries, so has the market for catering, which is the largest budget line item for a meeting or event. Clients have become more demanding and at the same time more price-conscious. This has caused catering professionals and meeting and event planners' job responsibilities to change. Caterers and planners now have more crossover responsibilities and over more varied functional areas than ever before. In response, the National Association for Catering and Events (NACE), as the oldest and largest catering association in the world, formally …

Listening To The Ranks: Perceptions Of The U.S. Air Force Occupational Health And Safety Training, Melissa Jo Breunig

Occupational health and safety hazards are abundant in military environments. Due to the hazardous occupational settings, injuries remain a public health concern in the United States military. Public health plays a critical role in injury reduction by addressing the need for comprehensive safety education training, and more specifically, exposure related injuries. A secondary data analysis was completed using Communication Theory as the overarching framework to analyze 13 qualitative interviews conducted with Airmen to gain their perceptions of the occupational health and safety training at Nellis and Creech Air Force Base (AFB). Pedagogy and training content were the two main themes …

Simultaneous Determination Of Multiple Actinide Elements In A Variety Of Soils Utilizing A Standardized Sequential Extraction Protocol, Sherry Alina Faye

UNLV Theses, Dissertations, Professional Papers, and Capstones

To obtain a better understanding of the mobility of actinide element contaminants in the environment, the association of the contaminants with specific host phases of soils and sediments must be investigated. This investigation is most commonly conducted using sequential extraction techniques that employ the selective dissolution of soil phases with increasingly aggressive chemical treatment. Though several sequential extraction studies exist in literature, conclusions cannot be made by direct comparison of data due to the lack of uniformity in the protocols used. This work aims to continue development of a standard sequential extraction protocol and expanding its capabilities to include the …

Designing A Process To Reliably Split Extracted Teeth To Access The Dental Root Canal, Happy Singh Ghag

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction

Mesenchymal stem cell (MSC) research is a contemporary topic in modern healthcare. These cells have the ability to divide and generate progeny, which then become committed to specific and distinctive end-stage phenotypes, such as cartilage or bone (Caplan 1991). MSCs have been isolated from a variety of tissues such as the umbilical cord, bone marrow, adipose tissue (Ding, Shyu & Lin 2011) and dental pulp (Takeda et al 2008). Although dental pulp is a viable source for MSCs, peer reviewed research has given limited attention to its retrieval process through intentional tooth splitting of extracted teeth. The purpose of …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The study examines the relationship between socio-economic and cultural determinants of health care service utilization in Ghana using Ghana Demographic and Health Survey (GDHS) 2008 data collected by Ghana Statistical Service (GSS) in which a two-stage sample design was used. The first stage involved a systematic sampling, with probability proportional to size, of 412 clusters using the 2000 Ghana Population and Housing Census as the sampling frame. At the second stage, systematic samples of 30 households from each cluster were selected, making a total of 12,360 sampled households. According to the GSS, data were not collected in some of the …

Digital Behavior Intervention Plans: Effects On General Education Teacher Fidelity Of Implementation, Christopher G. Holcomb

UNLV Theses, Dissertations, Professional Papers, and Capstones

Students with disabilities often have behavior that interferes with classroom learning. Serious problem behaviors are identified as the most significant factor interfering with learning in the classroom. Unfortunately, chronic behaviors often lead to a student dropping out of school. Current research typically focuses on areas of intervention for these students with little attention towards teacher fidelity of implementation of these interventions. Because of this, student's behavior intervention plans may not show effectiveness (e.g., progress monitoring, data driven decisions). It is important that researchers begin to explore systematic improvements in fidelity of implementation of behavior intervention plan components for general education …

Who Or What Should I Be Like? The Self-Assessment Of Sexual Desire, Caroline Maykut

UNLV Theses, Dissertations, Professional Papers, and Capstones

The construct of sexual desire has been notoriously difficult to capture and measure, in part as a function of questionable methods of sexual desire assessment. Due to problems finding an accurate, objective marker of sexual desire, research has relied on self-report. One notable difficulty with self-reported desire assessment is the lack of information on the context in which these assessments are made. The only available data focuses on relative assessment of sexual desire within couples, and ignores broader social and cultural contexts. The present study investigated men and women's perception of sexual desire discrepancies between themselves and other people and …

Factors Associated With Rapid Readmission Among Nevada State Pyschiatric Hospital Patients, Christopher Owen Moore

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rapid readmission (RR) of psychiatric patients within 30 days of discharge places a costly burden on state psychiatric facilities and may be an indicator of suboptimal service provision. Several studies have previously considered RR to inpatient facilities, but there is a lack of information available about the variables associated with RR of psychiatric patients to state-operated inpatient facilities in Nevada. This study attempts to identify factors associated with RR at a southern Nevada state psychiatric hospital. Participants included 7,177 patients admitted between May 1, 2012 and April 30, 2014. All 12,068 admissions, including 2,220 RR, were reviewed, and rapid readmits …

The Presentation Of Childhood Parental Divorce In Adulthood: A Retrospective Phenomenological Study, Sheala Catherine Morrison

UNLV Theses, Dissertations, Professional Papers, and Capstones

There has been a wealth of research aimed at developing an understanding of the way in which the experience of divorce impacts children. However, adult children of divorce have been widely underrepresented in this literature, much of which is outdated being at least ten years old. With shifting societal attitudes and the transformation of the family system since the 1990's it is crucial that the research is updated in order to stay up on the way children and families are impacted in today's society. The purpose of this study was to hear directly from adults who experienced their parents' divorce …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lung cancer is the leading cause of cancer death in both men and women in the United States. Nevada shows moderate incidence rates of lung cancer for men but high rates for women. Little is known about the lung cancer experience and survival characteristics of the nearly 2000 new cases occurring every year in the State. The purpose of this study was to measure the extent to which geographic area of residency, gender, race, health insurance, social economic status (SES) and stage at diagnosis were associated with survival in patients diagnosed with lung cancer in Nevada. This was a retrospective …

A Combined Therapeutic Regimen Of Buspirone And Environmental Enrichment Is More Efficacrious Than Either Alone In Enhancing Spatial Learning In Brain-Injured Rats, Christina M. Monaco, Kory M. Gebhardt, Sarah M. Chlebowski, Kaitlyn E. Shaw, Jeffrey P. Cheng

PCOM Scholarly Works

Abstract Buspirone, a 5-HT1A receptor agonist, and environmental enrichment (EE) enhance cognition and reduce histopathology after traumatic brain injury (TBI) in adult rats, but have not been fully evaluated after pediatric TBI, which is the leading cause of death in children. Hence, the aims of this study were to assess the efficacy of buspirone alone (Experiment 1) and in combination with EE (Experiment 2) in TBI postnatal day-17 male rats. The hypothesis was that both therapies would confer cognitive and histological benefits when provided singly, but their combination would be more efficacious. Anesthetized rats received a cortical impact or sham …

Proliferative Index And Microvessel Density As Potential Prognostic Markers Of Canine Oral Malignant Melanomas, Nan Choisunirachon, Yuiko Tanaka, Kohei Saeki, Nobuo Sasaki, Ryohei Nishimura, Takayuki Nakagawa

The Thai Journal of Veterinary Medicine

Several reports have indicated the prognostic significance of the proliferative index (PI) and microvessel density (MVD) in canine oral malignant melanomas (MM). However, a correlation between the PI and MVD of oral MM in dogs has never been elucidated. Here, we evaluated the expression of Ki-67 and CD31 using double immunofluorescence staining to investigate the correlation of PI with MVD in 37 spontaneous canine oral MMs. No correlation was found between the MVD and PI values or between those and any clinicopathologic findings. However, a correlation was found between the PI value and both clinical stage (p = 0.0453) and …

Characterization Of Femur, Mandible And Bone Marrow-Derived Mesenchymal Stromal Cells From Streptozotocin-Injected Mice, Philaiporn Vivatbutsiri, Nunthawan Nowwarote, Chenphop Sawangmake, Suconta Chareonvit, Prasit Pavasant, Thanaphum Osathanon

The Thai Journal of Veterinary Medicine

Streptozotocin injection is simply shown to promote hyperglycemic condition in several species. In the present study, we aimed to characterize the femoral and mandibular bone features of streptozotocin-induced diabetic mice. In addition, the characteristics of bone marrow-derived mesenchymal stromal cells were evaluated. Results showed that streptozotocin injection resulted in significant weight loss and increase in fasting blood glucose levels in the animals. Compared to the control mice, significantly greater bone surface/bone volume value was noted in the mandible and the femur. On the contrary, trabecular thickness was significantly decreased in the metaphysis area of the femur. Further, the bone volume/total …

Hemoglobin A1c And The Diagnosis Of Diabetes And Prediabetes In Children And Adolescents, Jennifer Mcguire Hitt

Theses and Dissertations (ETD)

Although the American Diabetes Association (ADA) adopted the use of the glycated hemoglobin (A1C) test as a method of diabetes and prediabetes diagnosis, the ADA has not developed firm guidelines concerning the use of the A1C test in children and adolescents, as research has not validated thresholds in this group. Diabetes and prediabetes are diseases influenced by multiple factors, including race and ethnicity, age, vitamin D deficiency, and body mass index (BMI). The purpose of this study was to determine the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the A1C test compared to the gold …

Effect Of Nedd4 Haploinsufficiency On Insulin Sensitivity, Adiposity And Neuronal Behaviors, Jingjing Li

Theses and Dissertations (ETD)

The neural precursor cell expressed developmentally down-regulated gene 4 (NEDD4) is a HECT-type E3 ubiquitin ligase that has received broad attention in recent years. Many of its reported substrates are active players in metabolism, implying a potential role of NEDD4 itself in metabolic regulation. Since homozygous Nedd4 deletion leads to embryonic or perinatal lethality, we investigated the function of NEDD4 in metabolic regulation in vivo, using Nedd4- haploinsufficient mice in a high fat diet-induced obesity (HFDIO) model.

Our studies show that Nedd4-haploinsufficient mice fed a normal diet (ND) exhibited decreased body weight in both genders and proportionally reduced tissue mass …
