Sediment Provenance Study Of The Lower Hamilton Group: An Analysis Of The Organic-Rich Facies And Its Depositional History, Luke Patrick Fritz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Currently, insufficient geological models exist to explain the variability and distribution of TOC in the Marcellus Shale, within the Hamilton Group. TOC is one of the several limiting factors for natural gas production within the Marcellus Shale basin. One possible explanation for the low TOC regions is that detrital dilution was variable across the basin, with different sediment sources contributing detritus to low TOC areas, compared to surrounding regions with higher TOC. This hypothesis is tested by analyzing the source composition of inorganic detritus, using elemental and mineralogical proxies, with two cores in the Hamilton Group. The Armstrong #1 core …

The Food Bank Fix: Hunger, Capitalism And Humanitarian Reason, Joshua David Lohnes

Graduate Theses, Dissertations, and Problem Reports (ETD)

Drawing on a five-year institutional ethnography of Humanitarian Food Networks (HFNs) in West Virginia, this dissertation explores the moral, political and economic place of the food bank in the corporate environmental food regime. I develop the concept of the food bank fix to theorize the paradoxical relationships between the state, the shadow state, food corporations, local charities and food banks that tie HFNs across the United States together through humanitarian reason. I argue that food banks damp the grinding contradictions of a society awash in food surpluses even as a significant proportion of the population remains at risk of hunger. …

Probability Discounting Of Lewis And Fischer 344 Rats: Strain Comparisons At Baseline And Following Acute Administration Of D-Amphetamine, Jenny E. Ozga

Graduate Theses, Dissertations, and Problem Reports (ETD)

Risky choice can be defined as choice for a larger, uncertain reinforcer over a smaller, certain reinforcer when choosing the smaller alternative maximizes reinforcement. Risky choice is studied using various procedures in the animal laboratory; one such procedure is called probability discounting. There are many variables that contribute to risky decision-making, including biological and pharmacological determinants. The present study assessed both of these variables by evaluating dose-response effects of d-amphetamine on risky choice of Lewis (LEW) and Fischer 344 (F344) rats. The probability-discounting procedure included discrete-trials choices between one food pellet delivered 100% of the time and three food …

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 …

Does Emotional Distress Tolerance Predict Fear Responding In A Heights-Fearful Sample?, Amber Lynn Billingsley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Emotional distress tolerance—or the ability to withstand negative emotional states—is considered a transdiagnostic risk factor for psychopathology. Although it is theorized to play an important role in anxiety, research aiming to delineate the relationship between anxiety and emotional distress tolerance is lacking. The current study tested whether an individual’s self-reported emotional distress tolerance predicted avoidance in the presence of feared stimuli using a heights-fearful sample. Moreover, the study tested whether emotional distress tolerance predicted other relevant in-the-moment fear responses, such as peak anxiety, anxious cognitions, and bodily sensations while in a heights scenario. Participants (N = 85) completed a …

As a result, rotary instrument manufacturers have developed files that have a minimal effect on original root canal anatomy. This study used Finite Element Analysis to investigate the dental biomechanical effect of rotary instrumentation during root canal therapy. The aim of this study is to …

Multidimensional Analysis Of Vulnerability: Methodological Advances And A Case Study From Malawi., Park Mcmillan Muhonda

Graduate Theses, Dissertations, and Problem Reports (ETD)

Since 1990s rural households in Malawi, constituting 85% of the population, have experienced deepening livelihood vulnerability, often manifested as persistent food insecurity. Livelihood crises have since been blamed on or attributed directly to weather perturbations/climatic shocks i.e. El-Nino induced climate variability/drought conditions. This study revealed that persistent livelihood crisis in rural Malawi cannot be attributed to or squarely blamed on weather shocks alone, rather it is at the intersection of various livelihoods shocks that rural livelihood vulnerability in Malawi is exacerbated i.e. worsening and deepening.

Thus, rural livelihood vulnerability to climate shocks in Malawi is manifest not in isolation but …

The Potential Promises And Pitfalls Of Using Local Norms For Gifted Identification, Marla S. Hartman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Who are the gifted? This question has plagued the field since its inception. Historically, gifted education has been predicated on the values of the Caucasian, upper- to middle-class majority. As a result, underrepresentation of students from economically disadvantaged and culturally diverse families have been well documented in the literature and continues to this day. Some scholars have suggested the use of expanded definitions of giftedness to increase participation of students from underrepresented segments of the population. This study used regression and hierarchical linear models to predict the proportion of students identified across various thresholds focusing on how definitions impacted differential …

Student-Instructor Out-Of-Class Communication: A Media Multiplexity Approach, Cathlin V. Clark-Gordon

Graduate Theses, Dissertations, and Problem Reports (ETD)

The present set of studies examined media multiplexity theory (MMT; Haythornthwaite, 2005) in the context of student-instructor out-of-class communication (OCC) in two samples: undergraduate and graduate students. It was predicted that student-instructor tie strength (closeness) would lead to a greater number of modes used for OCC, and subsequently, the number of modes used for OCC would predict positive classroom outcomes, including communication satisfaction, cognitive and affective learning, and motivation. It was also predicted that the effect of closeness on the number of modes used for OCC would be moderated by student’s enjoyment of online communication, insofar as it would suppress …
