Time-Dependent Deformation And Associated Failure Of Roof In Underground Mines, Yuting Xue

Graduate Theses, Dissertations, and Problem Reports (ETD)

In underground coal mines, roof falls are a major contributor to injuries and fatalities. Studies have related the occurrence of roof fall to weak immediate roof, high horizontal stress, entry orientation, etc. An often-neglected factor in studies on this topic has been the influence of time-dependent behavior of the roof rock on roof falls. The time-dependent roof failure activity involves both intact and failed rocks. Numerical simulation techniques are available that include time-dependent behavior; however, they lack constitutive models that consider both the intact and the failed behavior of rock. In addition, input properties for the creep models only include …

Findings illustrate the predictive value of credibility to trust within the context of political news coverage. Additionally, this study shows that individuals exhibit higher perceptions of trust and credibility towards fact-based political coverage as opposed to interpretive …

Copper-Catalyzed Regioselective Boracarboxylation Of Vinyl Arenes: Catalytic Efficiency And Synthetic Utility, Trina M. Perrone

Graduate Theses, Dissertations, and Problem Reports (ETD)

Hetero(element) carboxylation is an appealing transformation that involves the installation of CO2 and another hetero(element) in one step. This transition metal-catalyzed one-pot synthesis provides a route to achieve highly functionalized carboxylic acid products with an abundant and cheap C1 feedstock. This difunctionalization also avoids the use of reactive metal hydride species, which is a prominent limitation of hydrocarboxylation chemistry. A copper-catalyzed regioselective boracarboxylation of vinyl arenes has been developed to access pharmaceutically relevant β-boryl-α-aryl propionic acid products. One drawback of this reaction is the necessity for high catalyst loading to achieve catalytic turnover. To circumvent this issue, the reduction of …

Evaluating Post-Fire Plantation Restoration In A Mixed Conifer Forest In The Sierra Nevada, Iris C. Allen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Forests in the western United States have experienced a shift from historical disturbance regimes in the past century. Many of these changes were induced by European settlers logging the forests and suppressing fires. In the past, the dry mixed conifer forests of California’s Sierra Nevada mountains experience frequent, low to mixed severity fires. This fire regime helped maintain a heterogeneous landscape comprised of groups of trees and openings. However, due to fire suppression and high grading logging, forest structure has changed; there are less openings and more small, fire-intolerant trees that can carry a fire into the forests crown. The …

An Investigation Of The Relation Between Mindfulness And Self-Esteem Stability, Cameron Grant Ford

Graduate Theses, Dissertations, and Problem Reports (ETD)

Self-esteem stability is the magnitude of the short-term fluctuations in one’s immediate feelings of self-worth (Kernis, 2005). Stable self-esteem is associated with several psychological benefits, such as lower depression (Kernis et al., 1998). However, it is unknown what factors lead to self-esteem stability. Because mindfulness promotes a nonjudgmental orientation whereby thoughts, feelings, and reactions are viewed as transient events that do not necessarily represent objective reality, mindfulness might be associated with more stable self-esteem. Thus, the present research examined the relation between mindfulness and self-esteem stability. Undergraduates (N = 190) were randomly assigned to one of three conditions: mindfulness …

Untangling The Reciprocal Relation Of The Behavioral And Physiological Immune Systems, Baris Sevi

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the past decade, there has been an exponential increase in the study of the Behavioral Immune System (BIS), a suite of psychological processes that serves an infectious disease avoidance function. The BIS is proposed to be inherently intertwined with the physiological immune system. However, very few studies have actually demonstrated this fundamental, theoretical assumption. The purpose of this thesis was to test the possible relation between the physiological and behavioral immune systems in two studies. In Study 1 (N = 388), the relation between implied activation of the physiological immune system and BIS sensitivity was examined. Participants who reported …

Behavioral And Anti-Inflammatory Effects Of Magl Inhibition In A Mouse Model Of Inflammatory Arthritis, Floyd Franklin Steele Iii

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cannabinoids have analgesic and anti-inflammatory properties. For example, in preclinical models of acute inflammatory pain, cannabinoid receptor subtype 2 (i.e., CB_2, Table 1) agonists decrease paw inflammation and resulting pain. Yet, the anti-inflammatory properties of cannabinoid receptor manipulation in chronic inflammatory pain states are unknown. Monoacylglycerol lipase (MAGL) is the primary catabolic enzyme of the endocannabinoid (i.e., endogenous cannabinoid ligand) 2-arachidonoyl glycerol (i.e., 2-AG). Compounds that inhibit MAGL indirectly increase tissue levels of 2-AG by preventing its catabolism. MAGL inhibitors demonstrate efficacy in acute models of inflammatory/rheumatic disease. Thus, in this study, the MAGL inhibitor JZL184 was tested …

Choose Your Own Lecture: Students’ Motivational Resources As A Consequence Of Autonomy-Supportive Instruction, James P. Baker

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this dissertation was to extend the self-determination theory literature by investigating the utility of the choose your own lecture method of instruction. This method of instruction allows students to control the direction of a lesson. In line with the theoretical propositions of SDT, the researcher hypothesized that this style of teaching would support students’ inner motivational resources (i.e., autonomy-need satisfaction and intrinsic motivation) and in turn, foster students’ interest in the topic of the lesson, free-choice persistence, cognitive learning, affect for the course, and expressive dissent. A 50-minute live-lecture experiment on environmental communication (climate change, risk communication, …

Genetic And Pharmacologic Studies Towards Prevention Of Opioid Use Disorder, Shane W. Kaski

Graduate Theses, Dissertations, and Problem Reports (ETD)

Endogenous opioids mediate both analgesic and affective responses to stress. While the mu opioid receptor (MOR) produces the reinforcing euphoric effects responsible for the high abuse potential of traditional opioid analgesics, the kappa opioid receptor (KOR) is hypothesized to mediate the dysphoric component of stress. With increasing rates of opioid addiction, extensive research efforts are focused on better understanding each of these systems and how they interact, with the goal of developing less addictive pain management strategies and better approaches to addiction treatment. With this in mind, we conducted both clinical and pre-clinical studies aimed at developing better treatment strategies …

Acute stress to mitochondrial regulation (inhalation toxicology) as well as chronic (type 2 diabetes mellitus) was examined. Using a FVB transgenic microRNA-378a mouse knockout model, the cardiovascular impact derived from altering the …

A Randomized Controlled Trial Of Parent-Child Interaction Therapy With And Without Incentives In A Community Mental Health Setting, Lauren Borduin Quetsch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Disruptive behavior disorders (e.g., oppositional defiant disorder, conduct disorder) are the leading cause of referrals for children in mental health settings. Significant advancements in the implementation and dissemination of evidence-based family therapies have yielded successful reductions in these problem behaviors while also promoting long-term outcomes. Unfortunately, effective interventions such as Parent-Child Interaction Therapy (PCIT) are plagued with high rates of attrition and low rates of homework completion in community clinics. The current research study focused on evaluating the use of low cost incentives to increase retention and homework adherence in PCIT for a sample of low income, largely Hispanic families. …

Low-Power Reconfigurable Sensing Circuitry For The Internet-Of-Things Paradigm, Alexander Dilello

Graduate Theses, Dissertations, and Problem Reports (ETD)

With ubiquitous wireless communication via Wi-Fi and nascent 5th Generation mobile communications, more devices -- both smart and traditionally "dumb" -- will be interconnected than ever before. This burgeoning trend is referred to as the Internet-of-Things. These new sensing opportunities place a larger burden on the underlying circuitry that must operate on finite battery power and/or within energy-constrained environments. New developments of low-power reconfigurable analog sensing platforms like field-programmable analog arrays (FPAAs) present an attractive sensing solution by processing data in the analog domain while staying flexible in design. This work addresses some of the contemporary challenges of low-power wireless …

Minimizing Trihalomethane Formation Through Source Water Monitoring And Optimizing Treatment Practices, Nashid Mirza

Graduate Theses, Dissertations, and Problem Reports (ETD)

Trihalomethanes, a family of halogenated disinfection byproducts, are prevalent in finished drinking water. According to USEPA’s Disinfectants and Disinfection Byproducts Rules (DBPRs), the regulatory standard of the total trihalomethanes (TTHMs) is 80 μg/L, and water treatment plant operators are required to closely monitor TTHMs in the finished water on a quarterly basis. Although total organic carbon (TOC) has been identified as a precursor for the TTHMs, knowledge gaps still exist in how specific water and treatment related factors (e.g., intake water quality, seasonal variation, contact time, and treatment train) affect TTHMs formation. Focusing on water treatment plants in southwestern Pennsylvania, …

Psychological Trauma And Resilience Of Police Officers Involved In An Ambush: An Exploratory Study, Erin A. Teaff

Graduate Theses, Dissertations, and Problem Reports (ETD)

Law enforcement officers are widely recognized as having one of the most dangerous and stressful occupations, which can lead to lasting physical and psychological impacts. While research has examined the psychological trauma and resilience experienced by police officers, there have been very few research studies involving ambushes. Due to the continued risk of ambushes on police officers, gaining insight into the trauma and resilience of officers during these types of situations would be beneficial in providing psychologists with information to aid in their treatment officers involved in an ambush and similar unprovoked attacks. The primary aim of this study was …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Raman spectroscopy, recognized as a powerful analytical technique, has been widely employed in many fields especially in the detection of hazard material containing in food or water. However, multiplexed analyte quantification based on Raman spectra remains a challenge due to the difficulties in accurate and precise modeling of the relationship between multiple analyte concentrations and dense spectral data with noise.

In this work, a statistical procedure was developed to efficiently generate high-quality calibration models quantifying the analyte concentrations versus spectra relationship. The resulting calibration models are able to provide estimated concentration ranges (which reflect both point and uncertainty estimates) for …

Comparing The Effects Of Swimming Exercise And Dissolved Oxygen On Important Performance Parameters Of Early-Rearing Atlantic Salmon Salmo Salar And Rainbow Trout Oncorhynchus Mykiss., Thomas B. Waldrop

Graduate Theses, Dissertations, and Problem Reports (ETD)

Swimming exercise (bodylenghts/sec), and dissolved oxygen (DO), are important environmental variables in aquaculture. While there is an obvious physiological association between these two parameters, their interaction has not been adequately studied in Atlantic salmon, Salmo salar and Rainbow trout, Oncorhynchus mykiss. Since both variables can be easily manipulated in modern aquaculture systems, we sought to assess the impact of these parameters, alone and in combination, on the performance, health, and welfare parameters of the two species. Atlantic salmon and Rainbow trout were stocked into twelve circular 0.5 m³ tanks and exposed to either high (1.5-2 BL/s) or low …

Utilizing screen-printed carbon electrodes (SPCEs), a fast, simple, and sensitive approach toward the detection, identification, and quasi-quantitation of fentanyl was achieved both in an electrochemical cell and as a drop on the electrode surface. Electro-oxidation of fentanyl at the electrode was demonstrated using adsorptive stripping square-wave voltammetry between -0.5 V and +1.6 V with 100 mM Tris-HCl buffer at pH 8.5 as supporting electrolyte. Parameter optimization was conducted during method development to include supporting electrolyte and pH, electrochemical technique, pre-treatment and equilibration time, and various surface modifications. The simplest method utilizing an unmodified SPCE was determined to be appropriate for …

Factors Related To Collaborative Willingness In Surrogate Decision-Making Situations From The West Virginia Post., Rachael Spalding

Graduate Theses, Dissertations, and Problem Reports (ETD)

If a patient becomes unable to adequately express preferences for medical care, another individual called a “surrogate” may be consulted to make treatment decisions. Surrogates may be asked to indicate patient preferences on the Physician Order for Scope of Treatment (POST), a new type of advance directive completed with patients who are estimated to have less than one year left to live. Research from the shared decision-making literature indicates that collaboration can be a valuable means of enhancing patient satisfaction with their decisions. The current study examined how certain psychological and demographic variables predicted the extent to which participants desired …

Crown-Level Mapping Of Tree Species And Health From Remote Sensing Of Rural And Urban Forests, Fang Fang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tree species composition and health are key attributes for rural and urban forest biodiversity, and ecosystem services preservation. Remote sensing has facilitated extraordinary advances in estimating and mapping tree species composition and health. Yet previous sensors and algorithms were largely unable to resolve individual tree crowns and discriminate tree species or health classes at this essential spatial scale due to the low image spectral and spatial resolution. However, current available very high spatial resolution (VHR) remote sensing data can begin to resolve individual tree crowns and measure their spectral and structural qualities with unprecedented precision. Moreover, various machine learning algorithms …

Description Of Motor Control Using Inverse Models, Anton Sobinov

Graduate Theses, Dissertations, and Problem Reports (ETD)

Humans can perform complicated movements like writing or running without giving them much thought. The scientific understanding of principles guiding the generation of these movements is incomplete. How the nervous system ensures stability or compensates for injury and constraints – are among the unanswered questions today. Furthermore, only through movement can a human impose their will and interact with the world around them. Damage to a part of the motor control system can lower a person’s quality of life. Understanding how the central nervous system (CNS) forms control signals and executes them helps with the construction of devices and rehabilitation …

Leveraging Writing And Photography Styles For Drug Trafficker Identification In Darknet Markets, Wei Song

Graduate Theses, Dissertations, and Problem Reports (ETD)

Due to its anonymity, there has been a dramatic growth of underground drug markets hosted in the darknet (e.g., Dream Market and Valhalla). To combat drug trafficking (a.k.a. illicit drug trading) in the cyberspace, there is an urgent need for automatic analysis of participants in darknet markets. However, one of the key challenges is that drug traffickers (i.e., vendors) may maintain multiple accounts across different markets or within the same market.

To address this issue, in this thesis, we propose and develop an intelligent system named uStyle-uID leveraging both writing and photography styles for drug trafficker identification at the first …

Occupational Fraud: Executive Compensation And Enforcements Against Auditors And Perpetrators., Erlina Papakroni

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation is comprised of three studies that examine the association of executive compensation with financial statement fraud and enforcements pursued against the independent auditor and the principal perpetrators when occupational fraud is detected.

The first study examines competing, though non-mutually exclusive, hypotheses for the path that equity compensation follows on its way to financial misreporting. We find that firms that experience financial statement fraud pay their executives higher levels and a higher proportion of equity compensation across the entire executive’s tenure. This starts in the first year of an executive’s tenure and continues up until the fraud period. These …

Shame And Guilt: The Good, The Bad, And The Ugly, Raika Sadeghein

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the past few decades, we have witnessed a growing body of literature on emotions in the consumer behavior domain. Emotions are defined as “mental states of readiness that arise from appraisals of events or one’s own thoughts” (Bagozzi, Gopinath, & Nyer, 1999, p. 184). Marketers have examined the role of emotions as stimuli, mediators, moderators, and responses to the environment. The broad topic of emotions includes subtopics such as impact of emotions on consumption, attitudes, and behavioral intentions, emotional responses to market stimuli, and the impact of emotions on cognition. However, although the study of emotions is pivotal to …

Elucidating A Common Mechanism Of Proteasome Impairment In Neurodegenerative Disease And Its Pharmacological Intervention, Tiffany Ann Thibaudeau

Graduate Theses, Dissertations, and Problem Reports (ETD)

Proteostasis is maintained by several systems in the cell including the ubiquitin-proteasome system (UPS), chaperones, chaperone-mediated autophagy, and macroautophagy. The UPS is the principle route for the degradation of intracellular misfolded, damaged, or unneeded cellular proteins and has a critical role essential every cell process, including: cell cycle progression, transcriptional regulation, genome integrity, apoptosis, immune responses, and neuronal plasticity. When the efficiency of protein degradation is perturbed, misfolded and damaged protein aggregates can accumulate to toxic levels and cause neuronal dysfunction, which may underlie many neurodegenerative diseases. It is widely appreciated that soluble oligomers of misfolded proteins (e.g. Aβ, Alzheimer’s; …
