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 …

A Review On The Invasion Ecology Of Amur Honeysuckle (Lonicera Maackii, Caprifoliaceae), A Case Study Of Ecological Impacts At Multiple Scales, Rachel E. Mcneish, Ryan W. Mcewan

Invasive species are of global importance because of their impacts on ecological communities, habitat structure, native community dynamics, and ecosystem processes and function. Scientists and conservation managers are increasingly focusing on the biological impacts of invasive species and on devising management practices that emphasize the health of ecosystems based on measured biological processes. 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 …

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 …

Rising Against The “Enemies Of The Church”: The Dynamics Of Russian Desecularization And The Making Of Its Punitive Regime, Rachel Lynn Schroeder

Dissertations

This study makes an original contribution to theorizing desecularization, which Karpov (2010) defines as “a process of counter-secularization, through which religion reasserts its societal influence in reaction to previous and/or co-occurring, secularizing processes.” Existing theory states that desecularization is agency driven, involves social actors and activists with specific interests, ideologies and strategies. However, the theory does not explain the dynamics whereby desecularization takes place and a particular desecularizing regime—in structural and normative form and symbolic and discursive content—develops through social action and achieves hegemonic status. This dissertation fills this important gap by asking: How and why, in the anomic post-Soviet …

An Evaluation Of The Acceptability And Effects Of A Computer-Delivered Values-Based Behavioral Activation Treatment For Depression Among Older Adults, Kellie Reynolds

Dissertations

Depression is a common psychological disorder among older adults and is associated with serious secondary effects to health and social well-being. Behavioral activation has been found to be an efficacious treatment for depression. However, there is limited research on the treatment effects of behavioral activation with older adults. In general, older adults under-utilize mental health treatments. Computer-delivered treatments have been developed to address access and under-utilization. The purpose of this dissertation was to evaluate the acceptability and effects of a computer-delivered values-based behavioral activation treatment for depression in older adults. This study consisted of two phases. Phase I consisted of …

Friedrich List And The Imperial Origins Of The National Economy, Onur Ulas Ince

Research Collection School of Social Sciences

This essay offers a critical reexamination of the works of Friedrich List by placing them in the context of nineteenth-century imperial economies. I argue that List's theory of the national economy is characterised by a major ambivalence, as it incorporates both imperial and anti-imperial elements. On the one hand, List pitted his national principle against the British imperialism of free trade and the relations of dependency it heralded for late developers like Germany. On the other hand, his economic nationalism aimed less at dismantling imperial core-periphery relations as a whole than at reproducing these relations domestically and expanding them globally. …

A Functional Analysis Of Leader Behavior In A Behavioral Health Setting, Jason White

All Theses And Dissertations

A requirement for Maine behavioral health organizations to provide all employees with evaluations lacks guidelines on how to evaluate leader behavior; best practices are to provide a multifaceted evaluation process that includes direct observation. A single-case research design and continuous partial interval recording procedures were conducted on a male behavioral health clinician leading clinical supervision in which the dependent variable was the clinician’s delivery of positive reinforcement and the independent variable was the provider’s increased discussion of case shares. The basic findings showed that leader behavior changed as follower behavior changed to manage the group and meet group goals. The …

Traditional Vs. Project-Based Learning: The Effects On Student Performance And Motivation In Honors Level Mathematics Courses, Sunletha Carter

Doctoral Dissertations and Projects

Since the charge by the National Council for Teachers of Mathematics (NCTM) to move away from the traditional learning (TL) method of instruction to more learner-controlled techniques, project-based learning (PBL) has been on the rise. This quasi-experimental nonequivalent control group design study compared the academic achievement of 122 eleventh and twelfth grade students who were instructed using PBL techniques, with a control group of their counterparts who were instructed using TL techniques, in honors level mathematics courses. Pretest and Posttest data collected from both groups of students were statistically analyzed using independent t-tests, and Analysis of Covariance (ANCOVA), respectively, since …

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 …

Heparin-Peptide Interactions, Jacqueline Anastasia Morris

Graduate Theses and Dissertations

Heparin is a polydispersed sulfated molecule that is part of the family called glycosaminoglycans found in the extracellular matrix and cell surfaces. This molecule is extremely important for the activation of proteins and protein-receptor interactions that are responsible for downstream cell signaling pathways. Heparin has been isolated from porcine intestine and used as an anticoagulant for the prevention of embolisms, heart thrombosis, and clotting during heart surgeries. This so-called miracle drug was in use until 2008, when isolated batches were found to be contaminated with other glycosaminoglycans similar to heparin. From 2008, there has been a dire need for a …

Dental Applications Of Natural-Origin Polymers In Hard And Soft Tissue Engineering, Hossein E. Jazayeri, Mina D. Fahmy, Mehdi Razavi, Brett E. Stein, Aatif Nowman, Radi Masri, Lobat Tayebi

School of Dentistry Faculty Research and Publications

Clinical advances in the treatment of dentoalveolar defects continue to evolve with the introduction of new innovations in regenerative medicine and tissue bioengineering. Recent developments in tissue engineering are aimed at safely and effectively regenerating a damaged or necrotic area by replenishing its cells and increasing surrounding gene expression. Various techniques have successfully given rise to porous scaffolds being used by clinicians to treat the defect and initiate the repair process. Tissue reconstruction using bioengineered scaffolds is advantageous over traditional autografting, since it prevents the instigation of pain and donor site morbidity while ultimately creating both the environment and machinery …

Behavioral Differences Between Native And Exotic Invertebrate Prey Affect Susceptibility To Predation By A Native Amphibian Predator, Zachary Cava

Biology Theses

Invasive species threaten global biodiversity via mechanisms that include altering the dynamics and structure of native food webs. Whereas much research has focused on how exotic species respond to native predators, less is known about how native predators are affected by invasive prey. Here I investigate the response of a rare and threatened native predator—the Eastern Hellbender (Cryptobranchus alleganiensis) to a high-profile invasive crayfish species, Orconectes rusticus. Hellbenders have declined throughout much of their range, and although the potential for exotic predators (i.e. sport fish) to negatively impact C. alleganiensis has been addressed, effects of exotic prey …

A Qualitative Descriptive Study Examining The Current State Of The New York 4-H Program From A Leader’S Perspective, Megan E. Tifft

Education Doctoral

Nonprofit organizations (NPOs) represent a fast-growing industry with significant value in today’s society. NPOs are filling gaps in providing services the government can no longer deliver and are considered an economic industry worth billions of dollars. As evidenced in research, NPOs are facing a multitude of challenges. Still, most of these challenges are addressed as standalone issues. Research has provided tools and suggestions for how leadership can address singular challenges; however, few researchers have examined challenges broadly. It has been confirmed that organizational leadership needs to understand, from a leader’s perspective, the challenges of the organization so that efforts can …

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 …

Tsunami Warning System, Amay Vijay Desai

Doctoral Dissertations and Master's Theses

The effects of a tsunami on a coastline can be devastating. In an attempt to mitigate the damages caused by tsunamis, and to provide coastal communities with evacuation alerts, it is essential to have early warning systems installed offshore. Tsunami early warning systems can detect the formation of tsunami waves long before they reach shore, providing coastal communities with information about the strength of an incoming tsunami.

Since providing accurate information about oceanic wave patterns is absolutely necessary to forecast the magnitude of a tsunami as it forms, the focus of this research is to develop a novel approach which …

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 …

Increasing Caregiver Supervision Of Young Children: Teaching Scanning, Predicting Behavior, And Modifying For Safety, Natalie Truba

Dissertations

Unintentional injuries account for a significant number of child deaths and visits to the emergency department. Although increased supervision is routinely shown to be an effective method of preventing unintentional childhood injuries, few interventions systemically teach caregivers behavioral skills to supervise their children appropriately. The present study utilized a multiple baseline design to pilot test an intervention designed to increase caregiver supervision and decrease unintentional childhood injuries by training caregivers how to provide appropriate levels of supervision for their young children (ages 6 to 36 months). Specifically, caregivers were taught in the present study include: (1) scanning the environment (for …

The Lived Experience Of Individuals With Chronic Back And Neck Pain, Depression, And/Or Anxiety, Tara L. Palmeri

Dissertations

More than 1.5 billion people worldwide suffer from chronic pain (CP). People who experience chronic pain are 20 to 40% more likely to meet criteria for an anxiety disorder, and three to four times more likely to be clinically depressed than their pain-free counterparts. The relationship between CP and mental health has been studied quantitatively; however, few researchers have investigated co-morbid CP and mental health through a phenomenological lens. The subjective nature of the relationship is not comprehensively addressed within the literature.

This qualitative phenomenological study explored (a) how individuals with chronic back and/or neck pain (CBNP) experience, understand, and …

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 & …

Role Of Nanotechnology And Gene Delivery Systems In Trail-Based Therapies, George E. Naoum, Fady Tawadros, Ammad Ahmad Farooqi, Muhammad Zahid Qureshi, Sobia Tabassum, Donald J. Buchsbaum, Waleed Arafat

ETSU Faculty Works

Since its identification as a member of the tumour necrosis factor (TNF) family, TRAIL (TNF-related apoptosis-inducing ligand) has emerged as a new avenue in apoptosis-inducing cancer therapies. Its ability to circumvent the chemoresistance of conventional therapeutics and to interact with cancer stem cells (CSCs) self-renewal pathways, amplified its potential as a cancer apoptotic agent. Many recombinant preparations of this death ligand and monoclonal antibodies targeting its death receptors have been tested in monotherapy and combinational clinical trials. Gene therapy is a new approach for cancer treatment which implies viral or non-viral functional transgene induction of apoptosis in cancer cells or …

Frontier Security: The Case Of Brazil, John A. Cope, Andrew Parks

INSS Strategic Perspectives

Over the past three decades Brazil has greatly improved its ability to monitor and control its long border. Achieving better management of the complex frontier security problem required a great deal of patience, trial and error, organizational adaptation, and good leadership. The Brazilian experience yields a number of important lessons for Brazil and for its neighbors in the Western Hemisphere. Improving performance required subordination of military priorities to civilian authorities; the repositioning of forces; better military-police cooperation; interagency and international cooperation; investment in technologies to give Brazil an advantage in the contest for best situational awareness; a long-term commitment; and …

The Influence Of The Electric Supply Industry On Economic Growth In Less Developed Countries, Edward Richard Bee

Dissertations

This study measures the impact that electrical outages have on manufacturing production in 135 less developed countries using stochastic frontier analysis and data from World Bank’s Investment Climate surveys. Outages of electricity, for firms with and without backup power sources, are the most frequently cited constraint on manufacturing growth in these surveys.

Outages are shown to reduce output below the production frontier by almost five percent in Africa and by a lower percentage in South Asia, Southeast Asia and the Middle East and North Africa. Production response to outages is quadratic in form. Outages also increase labor cost, reduce exports …

A Visual Return-To-Home System For Gps-Denied Flight, Benjamin Paul Lewis

Theses and Dissertations

Unmanned aerial vehicle technology is rapidly maturing. In recent years, the sight of hobbyist aircraft has become more common. Corporations and governments are also interested in using drone aircraft for applications such as package delivery, surveillance and communications. These autonomous UAV technologies demand robust systems that perform under any circumstances. Many UAV applications rely on GPS to obtain information about their location and velocity. However, the GPS system has known vulnerabilities, including environmental signal degradation, terrestrial or solar weather, or malicious attacks such as GPS spoofing. These conditions occur with enough frequency to cause concern. Without a GPS signal, the …

The Relationship Between Fructose And The Metabolic Syndrome Risk Factors, Lauren C. Kania

Research Papers

Up until the last few decades, fructose was pretty much nonexistent in the human diet. Today it can be found in various processed foods and beverages including soft drinks, juice, and baked goods. These products comprise a large proportion of the human diet these days and consumption is high in children, adolescents, and young adults. Naturally, fructose is found in plant sources such as fruits and sugar cane. Today, high fructose corn syrup is used as a sweetener in many processed foods and drinks such as soda and fruit juices. High fructose corn syrups’ low production cost has increased its’ …

Pituitary Adenylate-Cyclase Activating Polypeptide Regulates Hunger- And Palatability-Induced Binge Eating, Matthew M. Hurley, Brian Maunze, Megan E. Block, Michael J. Reilly, Eugene Kim, Yao Chen, Yan Li, David A. Baker, Qing-Song Liu, Sujean Choi

Biomedical Sciences Faculty Research and Publications

While pituitary adenylate cyclase activating polypeptide (PACAP) signaling in the hypothalamic ventromedial nuclei (VMN) has been shown to regulate feeding, a challenge in unmasking a role for this peptide in obesity is that excess feeding can involve numerous mechanisms including homeostatic (hunger) and hedonic-related (palatability) drives. In these studies, we first isolated distinct feeding drives by developing a novel model of binge behavior in which homeostatic-driven feeding was temporally separated from feeding driven by food palatability. We found that stimulation of the VMN, achieved by local microinjections of AMPA, decreased standard chow consumption in food-restricted rats (e.g., homeostatic feeding); surprisingly, …
