Population Dynamics Of Black Bears In Northwestern South Carolina, Shefali Azad

All Theses

Black bears (Ursus americanus) are managed as a game species in the northwestern region of South Carolina. However, no formal research study has examined their long-term population trends. I used the Downing harvest population reconstruction technique to establish abundance trends. The total population in 2013 was estimated at about 412 bears, increasing from about 97 bears in 1998. I also derived abundance, density, average age, and sex ratios at a county-level to investigate differential stages of recovery. Overall my results suggest that in 1998-2013 Oconee county had a rapidly expanding population, Pickens county requires further investigation into potential bear overharvest, …

Repetitive, Pre-Anesthetic Fasting And Malnutrition In A Pediatric Oncology Population Undergoing Radiation Therapy, Laura P. Santibáñez

Dissertations and Theses (Open Access)

Background: Pediatric oncology patients often experience nutritional status changes, particularly malnutrition, which may adversely affect their outcomes. Although the consequences of malnutrition are elucidated, its causes remain unclear. A possible cause of malnutrition in pediatric oncology patients is repetitive, pre-anesthetic fasting prior to non-invasive procedures and treatments, such as anesthesia-assisted radiation therapy (AART). This exploratory study investigated the association between repetitive, pre-anesthetic fasting and non-fasting days and malnutrition in pediatric oncology patients receiving AART.

Procedure: A retrospective cohort of 138 pediatric oncology patients (£ 10 years of age) who received any type of radiation therapy (RT) with or without anesthesia …

Role Of Stress And Social Resources On Biomarkers And Fatigue In Staff Nurses: A Biobehavioral Approach, Mona Cockerham

Dissertations and Theses (Open Access)

Purpose

Consecutive 12-hr workdays can contribute to increased stress and fatigue and negative biological responses in nurses, potentially compromising quality of patient care and safety. The primary purpose of this study was to assess changes in stress, fatigue, and biological responses (salivary cortisol and alpha-amylase) over three consecutive 12-hr workdays in acute care nurses and how stress and social resources function in predicting fatigue and biological responses.

Methods

In a prospective study, 81 acute care nurses completed questionnaires and provided saliva samples four times: pre-shifts and post-shifts of day 1 and day 3.

Results

Although stress and biological responses did …

Animal Water Balance Drives Top-Down Effects In A Riparian Forest-Implications For Terrestrial Trophic Cascades, Kevin E. Mccluney, John L. Sabo

Biological Sciences Faculty Publications

Despite the clear importance of water balance to the evolution of terrestrial life, much remains unknown about the effects of animal water balance on food webs. Based on recent research suggesting animal water imbalance can increase trophic interaction strengths in cages, we hypothesized that water availability could drive top-down effects in open environments, influencing the occurrence of trophic cascades. We manipulated large spider abundance and water availability in 20 × 20 m open-air plots in a streamside forest in Arizona, USA, and measured changes in cricket and small spider abundance and leaf damage. As expected, large spiders reduced both cricket …

End-Of-Life Heart Failure Education With Staff Nurses; A Quality Improvement Project, Carisa Battah

Student Projects for Graduate Degrees

Heart failure (HF) is a serious diagnosis and a major public health concern. The symptoms can be exhausting and can vary from person to person with periods of acute exacerbations requiring hospital admission. It is important for hospital staff nurses to be able to speak with knowledge and comfort about end‐of‐life planning. The purpose of this quality improvement project was to increase nurses’ awareness of the functional classification systems of HF, options and timing for palliative care, and describe nurses’ intent to use the information in practice. Nurses reported planning on using the information to “Be more Sensitive and Listen.” …

Amur honeysuckle (Lonicera maackii (Rupr.) Herder) is a highly successful invasive shrub in forests of eastern North America. The scientific literature surrounding this species has grown in the past several decades as researchers have investigated L. maackii impacts across multiple ecological scales. In this review we …

Discriminative Stimulus Effects Of 3,4-Methylenedioxypyrovalerone And 4-Methylmethcathinone, Michael D. Berquist

Dissertations

Recent escalation in the popularity of recreational synthetic cathinone (“bath salts”) use has prompted numerous scientific investigations of the neurochemical and behavioral effects of 3,4-methylenedioxypyrovalerone (MDPV) and 4-methylmethcathinone (4-MMC), two of the more common chemical constituents of these illicit “bath salts”. Previous neurochemical and electrophysiological studies have revealed that MDPV functions as a blocker, and 4-MMC as a substrate, at monoamine transporters, and both produce transient increases in extracellular monoamines. In addition, previous research has demonstrated that MDPV and 4-MMC support self-administration in nonhuman experimental subjects, and their rewarding effects are observed when paired with contextual cues in nonhuman models …

Acceptance And Commitment Therapy For Adolescent Difficulties With Emotion Regulation: An Open Trial, Julissa A. Duenas

Dissertations

Research suggests that youth rates of mental health problems are high and that evidence-based treatments for these populations exist; however, there is a significant problem in accessibility of mental health services. Recent movements in the mental health field have shifted focus to transdiagnostic dimensions of behavior in attempt to target a broader range of psychological difficulties across larger populations. One such construct, emotion regulation, has been defined as an ability to have awareness and acceptance of emotions and control urges and impulses in order to behave towards a goal. Emotion regulation has been linked to numerous internalizing and externalizing behavioral …

Assessing Change In Attachment Security Of Adolescents At Residential Therapeutic Programs, Laura Santa Thum

Dissertations

Adolescents with significant, persistent behavioral and mental health problems are increasingly being treated in private residential treatment programs (RTPs). Recent research at such programs shows that adolescents’ symptoms improve over the course of treatment and that such positive results persist up to a year post discharge. This study attempts to address what is occurring below the symptom level by exploring if attachment security increases as symptoms improve over the course of treatment in private RTPs. The level of attachment security was assessed along the dimensions of attachment avoidance and anxiety as a general construct and according to specific relationships (with …

Establishing And Testing Conditioned Reinforcers: Evaluating The Effects Of The Discriminative Stimulus Procedure Using Intermittency With Individuals With Developmental Disabilities, Yannick A. Schenk

Dissertations

A common characteristic of individuals with developmental disabilities is a restricted range of interest. Developing procedures to establish new reinforcers for such individuals can promote the acquisition of new skills and ameliorate decreases in motivation related to satiation. Several procedures for conditioning reinforcers have shown to be effective in the research literature for establishing neutral stimuli as conditioned reinforcers. Most of this literature is basic research with animal subjects (e.g., rats, pigeons). Few applied studies have directly evaluated the use of these procedures. Additional research is necessary to determine their effectiveness. The purposes of this study were to: (a) evaluate …

Amplified Fragment Length Polymorphism (Aflp) Analysis Of Taeniatherum Caput-Medusae, An Invader Of Western U.S. Rangelands, Elizabeth Catherine Kent

Boise State University Theses and Dissertations

Biological invasions are one of the main drivers of global change, and thus one of the main factors contributing to a loss of biodiversity world-wide. Introduced species can destroy habitat through predation, grazing, and competition for resources; spread disease; alter disturbance regimes; and disrupt ecosystem services. Taeniatherum caput-medusae subsp. asperum (medusahead) is a winter-annual grass native to Eurasia and invasive in the westernUnited States. Medusahead dominates one million hectares of its invasive range and detrimentally affects the areas it inhabits through degradation of foraging value for livestock, increasing fire frequencies, and decreasing biodiversity. Previously, allozyme analyses have suggested this …

Nindanishinaabewimin: Ojibwe Peoplehood In The North American West, 1854-1954, Margaret Huettl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Anishinaabeg Peoples maintained sovereignty via peoplehood in the context of Settler colonial programs intended to confine and ultimately eliminate Indigenous sovereignty and identity. Although scholars have usually considered the late nineteenth and early twentieth centuries—defined by confinement, dispossession, and marginalization—as the nadir of Indian history, I explore the persistence of Anishinaabe sovereignty. Eschewing race and nationhood, ways of thinking embedded in Western European epistemologies, I rely on “peoplehood,” a theory developed by American Indian Studies scholars, to articulate Ojibwe sovereignty. Anishinaabeg, like many of the names Native Americans use to identify themselves, means “the people.” Inherent in peoplehood is sovereignty, …

Incomplete Denitrification In Thermus Species, Chrisabelle Mefferd

UNLV Theses, Dissertations, Professional Papers, and Capstones

Members the bacterial genus Thermus have been shown to be incomplete denitrifiers, terminating with nitrite or nitrous oxide (N2O). However, the ability to carry out denitrification and the evolution of nitrogen oxide reductase genes in Thermus remains poorly understood. This study tests the hypothesis that incomplete denitrification is common in Thermus and seeks to uncover patterns in the evolution of denitrification pathways in Thermus. Denitrification capacity was determined in a collection of 25 strains representing ten species of Thermus and phylogenetic analysis was performed to determine whether denitrification genes evolved horizontally in Thermus. No strains in this study reduced nitrate …

The Role Of Mfd In Stationary-Phase Oxidative Damage Repair In Bacillus Subtilis, Katelyn E. Porter

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since the 1950’s it has been shown that bacterial cells accumulate mutations even in non- dividing conditions, but how this type of mutation occurs is still highly debated. In Bacillus subtilis, Mfd, a precursor of the nucleotide excision repair (NER) system, mediates the formation of mutations in stationary-phase or non-replicating cells. In growing cells, Mfd recruits repair when RNA polymerase is stalled during transcription; it then recruits proteins from NER to repair damage. Here, we examine the hypothesis that Mfd mediates the formation of mutations by interacting with cellular components that repair reactive oxygen species (ROS), a natural byproduct of …

Development And Testing Of An Assessment To Measure Spatial Thinking About Enhanced Greenhouse Effect, Heather Jean Skaza

UNLV Theses, Dissertations, Professional Papers, and Capstones

Americans, in general, do not behave in environmentally sustainable ways. We drive cars and fly in planes that emit planet-warming carbon. We purchase food in nearly indestructible packaging that is not recycled or repurposed. We do not consider the environmental impact of the “stuff” stuffed into our grocery and department stores, most of which is made of materials that had to be dug out of the ground, leaving rivers and skies full of pollution in its place. Citizens have a responsibility to understand complex global and local environmental problems. A person’s ability to think about the way that an environmental …

Biogeochemistry Of A Saline, Alkaline, Terminal Lake Ecosystem In Transition; Walker Lake, Nevada, Katherine Lynn Willever

UNLV Theses, Dissertations, Professional Papers, and Capstones

Walker Lake is a saline, alkaline, terminal lake ecosystem located in west-central Nevada. For over one hundred years, anthropogenic streamflow diversions within the Walker River Basin have ultimately led to little or no water reaching Walker Lake, the basin’s terminus for water flow. These diversions have resulted in a >46 meter decrease in the lake surface altitude and increases in salinity and dissolved salt constituents that have caused the elimination of native fish species. This study examines how the lack of freshwater inflow has altered the physical, chemical, and microbiological structure of Walker Lake during the lake’s ongoing desiccation.

A​ Program Evaluation Of Outside Las Vegas’ Ymca Education Program, Robin Mendoza, Kevin Schmidt, Arcelia Barajas, Branson Chun

UNLV Theses, Dissertations, Professional Papers, and Capstones

Today, more than ever, society needs high-quality environmental education programs that succeed in moving values and changing behaviors in the direction of sustainability and conservation. The most common definition of outdoor education comes from "education in, about, and for the outdoors" (Donaldson and Donaldson, 1958, p. 63). They described outdoor learning as taking place “in” the outdoors and the subject matter being “about” nature or the outdoors. There are a variety of studies about “outdoor learning” with a large variation of topics, activities, settings and channels of delivery. The research discussed in this paper will vary slightly to demonstrate the …

The Social Structure Of Golfo Dulce Bottlenose Dolphins (Tursiops Truncatus) And The Influence Of Behavioural State, Kelsey Moreno, Alejandro Acevedo-Gutierrez

Faculty Publications

Ecological factors such as habitat and food availability affect the social structure of bottlenose dolphins (Tursiops spp.). Here, we describe the social structure of bottlenose dolphins (T. truncatus) in Golfo Dulce, Costa Rica, a semi-enclosed, fjord-like tropical embayment resembling a pelagic system. We also examine behaviour-linked social strategies by comparing social structure relative to behavioural state: feeding versus non-feeding. We analysed 333 sightings over 210 days from boat-based surveys. Despite the uniqueness of the area, the 47 analysed adults had a social structure similar to other populations: a well-differentiated fission-fusion society with sex-specific patterns of associations and aggression. These results …

Culturally Relevant Education For Rural Schools: Creating Relevancy In Rural America, Joshua J. Anderson

Dissertations

In this dissertation, I investigate the ways in which culturally relevant pedagogy is conceptualized and implemented by two secondary English Language Arts educators in one school district with a strong sense of rural identity. Culturally relevant pedagogy is considered by many professionals in the field of education to be an effective philosophy to inform instructional practices for narrowing the achievement gap of historically marginalized groups (Cummins, 1990; Gay, 2000; Ladson-Billings, 1994, 2000). A careful review of the literature on culturally relevant pedagogy reveals the discourse surrounding culturally relevant pedagogy has largely been dominated by urban voices (Cochran-Smith, 2003; Esposito & …

A System For Monitoring And Managing Indoor Air Quality And Environmental Conditions, Ali Ibrahim

Boise State University Theses and Dissertations

The quality of indoor air depends on different types of pollutant sources existing in a semi-enclosed environment. The sources can be biological, chemical, or toxic pollutants. These sources can cause health issues and discomfort for occupants. One of the indicators of poor indoor air quality is Carbon Dioxide (CO₂). CO₂ can be used to indicate the indoor air exchange rate. The lack of air exchange means higher levels of CO₂. High levels of indoor particulates can also be an indication of poor air quality. Due to the lack of fresh air, air circulation, and air …

Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, Deanna M. Boensch

Electronic Theses and Dissertations

At the western edge of the longleaf pine (Pinus palustris) range, federal land managers have burned the forests of Big Thicket National Preserve to bring back the structure and diversity of the longleaf pine forest. In the early 1990’s, a four year study was conducted by Rice University, and the National Park Service continued monitoring the study’s fire ecology research plots. After two decades of data collection, ordination was applied to species abundance data to examine changes in vegetation communities from a variety of prescribed fire treatments and controls. The vegetation data was separated by size class to include overstory, …

Double-Crested Cormorants, Brian S. Dorr, Kristi L. Sullivan, Paul D. Curtis, Richard Chipman, Russell D. Mccullough

Wildlife Damage Management Technical Series

The history of conflict between double-crested cormorants (Figure 1) and human interest in fisheries is long and convoluted. Following a low point in the 1970s, populations of cormorants expanded in North America, as did concerns about impacts on fisheries. By the late 1990s, natural resource agencies in 27 states reported losses of free-ranging fish stocks to cormorants. Agencies in 10 states, ranging from the Southwest to the Northeast, considered cormorant predation to be of moderate to major concern to fishery management.

Overall, double-crested cormorants are not major consumers of commercial and sportfish species. However, exceptions have been recorded at specific …

Bird Dispersal Techniques, Thomas W. Seamans, Allen L. Gosser

Wildlife Damage Management Technical Series

Conflicts between humans and birds likely have existed since agricultural practices began. Paintings from ancient Greek, Egyptian, and Roman civilizations depict birds attacking crops. In Great Britain, recording of efforts at reducing bird damage began in the 1400s, with books on bird control written in the 1600s. Even so, the problem persists. Avian damage to crops remains an issue today, but we also are concerned with damage to homes, businesses, and aircraft, and the possibility of disease transmission from birds to humans or livestock. Successful dispersal techniques should capitalize on bird sensory capabilities. If birds cannot perceive the dispersal technique, …

Geese, Ducks And Coots, John L. Cummings

Wildlife Damage Management Technical Series

Canada geese, snow geese, ducks, and American coots all have been implicated in agricultural crop and turf damage. Canada geese and snow geese that graze on winter wheat and rye crops can reduce subsequent grain and vegetative yields. Canada geese also cause serious damage to sprouting soybeans in spring and to standing cornfields in the autumn. The most common damage to agricultural resources associated with geese results from consumption of crops. Other impacts involve unacceptable accumulations of feces in pastures, trampling of emerging crops, and increased erosion and runoff from fields where the cover crop has been grazed. Canada geese …

Identifying And Addressing Soil Property Issues Affecting Roadside Vegetation Establishment, Xu Li, Martha Mamo, Walter H. Schacht, Tala Awada, Humberto Blanco-Canqui

Nebraska Department of Transportation: Research Reports

Attaining adequate vegetation cover along highways is important for NDOR to comply with EPA’s stormwater regulations. However, low plant cover is a common problem on shoulders (first 16 feet off the pavement) of many highways in Nebraska. The ultimate goal of this study is to identify cost-effective engineering solutions that assure adequate seed beds (i.e., soil conditions) for establishment of selected seeding mixtures. The objectives of this study are to (1) characterize the soil properties along roadsides where vegetation stands have not developed well, and (2) verify the effects of select soil property parameters on plant germination and establishment.
