Clarifying Resource Dependence: A Multi-Dimensional Approach To Dependence And Autonomy In Entrepreneurial Firms, Curtis R. Sproul Jan 2017

Clarifying Resource Dependence: A Multi-Dimensional Approach To Dependence And Autonomy In Entrepreneurial Firms, Curtis R. Sproul

Graduate Theses, Dissertations, and Problem Reports (ETD)

Entrepreneurial firms face dependence on other firms in the external environment to access resources critical for the development and survival of the firm. While substantial research has examined resource dependence and how firms may remedy such dependencies, the literature often fails to acknowledge key factors that can predict and explain firm behavior and outcomes in such situations. Firms are shown to enter into inter-organizational relationships in order to remedy resource dependencies, but studies typically evaluate such relationships according to their structure, rather than the resource being sought. Research also frequently ignores the role of autonomy in resource dependence. As gaining …

The Effect Of A Missing At Random Missing Data Mechanism On A Single Layer Artificial Neural Network With A Sigmoidal Activation Function And The Use Of Multiple Imputation As A Correction, Taron Dick Jan 2017

The Effect Of A Missing At Random Missing Data Mechanism On A Single Layer Artificial Neural Network With A Sigmoidal Activation Function And The Use Of Multiple Imputation As A Correction, Taron Dick

Graduate Theses, Dissertations, and Problem Reports (ETD)

Missing data is a common problem encountered in statistical analysis. However, little is known about how bias inducing missing at random missing data mechanisms affect predictive model performance measures such as sensitivity, specificity, error rate, ROC curves, and AUC. I investigate the effect of missing at random missing data mechanisms on a single layer artificial neural network with a sigmoidal activation function, equivalent to a binary logistic regression. Binary logistic regression is frequently used in health research and so it is a logical starting point to understand the effects of missing data on statistical learning models that could be used …

Effects Of Differential Drl Exposure On Interval Timing: Information Vs. Inhibition, Matthew L. Eckard Jan 2017

Effects Of Differential Drl Exposure On Interval Timing: Information Vs. Inhibition, Matthew L. Eckard

Graduate Theses, Dissertations, and Problem Reports (ETD)

Recent investigations focusing on interventions to improve self-controlled choice have centered upon timing processes. However, speculation still remains regarding the mechanism of these interventions. To investigate how these interventions have their effects, timing in mice was assessed using an 18-s peak procedure (18-s FI trials; 54-s peak trials). During an intervention phase, mice in three treatment groups experienced differential reinforcement of low rate (DRL) schedules of reinforcement. A control group received continued exposure to the peak procedure. After 36 DRL sessions, timing was reassessed in the peak procedure. In contrast to previous reports, the DRL intervention resulted in less precise …

Correlating Metastable-Atom Density, Reduced Electric Field, And Electron Energy Distribution In The Initiation, Transient, And Post-Transient Stages Of A Pulsed Argon Discharge, James B. Franek Jan 2017

Correlating Metastable-Atom Density, Reduced Electric Field, And Electron Energy Distribution In The Initiation, Transient, And Post-Transient Stages Of A Pulsed Argon Discharge, James B. Franek

Graduate Theses, Dissertations, and Problem Reports (ETD)

Argon emission lines, particularly those in the near-infrared region (700-900nm), are used to determine plasma properties in low-temperature, partially ionized plasmas to determine effective electron temperature [Boffard et al., 2012], and argon excited state density [Boffard et al., 2009] using appropriately assumed electron energy distributions. While the effect of radiation trapping influences the interpretation of plasma properties from emission-line ratio analysis, eliminating the need to account for these effects by directly observing the 3px-to-1sy transitions [ Boffard et al., 2012] is preferable in most cases as this simplifies the analysis. In this dissertation, a 1-Torr argon, pulsed positive column in …

Robust Specularity Removal From Hand-Held Videos, Priyaankadevi Guggilapu Jan 2017

Robust Specularity Removal From Hand-Held Videos, Priyaankadevi Guggilapu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Specular reflection exists when one tries to record a photo or video through a transparent glass medium or opaque surfaces such as plastics, ceramics, polyester and human skin, which can be well described as the superposition of a transmitted layer and a reflection layer. These specular reflections often confound the algorithms developed for image analysis, computer vision and pattern recognition. To obtain a pure diffuse reflection component, specularity (highlights) needs to be removed. To handle this problem, a novel and robust algorithm is formulated. The contributions of this work are three-fold.;First, the smoothness of the video along with the temporal …

An Examination Of The Consultation Component Of A Training Protocol For Parent-Child Interaction Therapy, Carrie B. Jackson

Graduate Theses, Dissertations, and Problem Reports (ETD)

There is a growing need to train clinicians in evidence-based treatments (EBTs) to increase the accessibility of research-informed treatments in community settings (Herschell, Kolko, Baumann, & Davis, 2010). Multi-component trainings, which commonly include ongoing support, are more effective than one-day workshops, reading treatment manuals, and other brief training methods. The present study examines the effectiveness of one form of ongoing support, consultation, as part of a multi-component training protocol. Thirty-two community-based clinicians were trained in Parent-Child Interaction Therapy (PCIT) as part of a statewide implementation effort, and data were collected on several training (e.g., knowledge) and implementation (e.g., acceptability) outcomes …

Bobcat Population Ecology In West Virginia, Stephanie Michelle Landry Jan 2017

Bobcat Population Ecology In West Virginia, Stephanie Michelle Landry

Graduate Theses, Dissertations, and Problem Reports (ETD)

Bobcats (Lynx rufus) are a popular furbearer and game species throughout their range in North America, where they serve as a top predator in many of their ecosystems. However, bobcat populations across their range declined during the 1800s and early 1900s due to overharvest. Overharvest and habitat loss in Europe also affected the Iberian lynx ( L. pardinus), resulting in the listing of all Lynx spp. under the Convention on International Trade in Endangered Species in 1977. Bobcats were listed under Appendix II, which required that state management agencies monitor their bobcat populations for stability. Since their listing, bobcat populations …

Microbial Quality And Pathogen Decontamination Strategies For Locally-Grown, Fresh Produce From West Virginia And Kentucky, Ka Wang Li Jan 2017

Microbial Quality And Pathogen Decontamination Strategies For Locally-Grown, Fresh Produce From West Virginia And Kentucky, Ka Wang Li

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study aimed to evaluate the microbiological quality/safety of fresh produce from farmers' markets (FM) and assess the post-harvest washing practice with antimicrobials to inactivate Salmonella and Listeria monocytogenes on fresh produce. In study I, 212 produce samples were tested for the presence of Salmonella and Listeria spp. using modified FDA-BAM methods. Aerobic plate counts (APCs), total coliforms (TCCs), and yeast/molds were analyzed on petri-films. Among the 212 samples, the APCs, TCCs, and yeast/molds were 3.72-5.63, 3.67-5.47, and 3.07-4.13 log CFU/g, respectively, with spinach containing the highest (P<0.05) populations. Among all tested samples, Salmonella enterica spp. enterica was detected on 18.6% of spinach, 10.9% of tomatoes, 18.5% of peppers, and 56.3% of cantaloupes, which is much higher than previous reported. Only 3.78% of the samples were confirmed for Listeria spp., and 50% of them were identified as L. monocytogenes, based on multiplex PCR results. Due to the high percentage of pathogens detected on the farmers' marker produce, an evaluation of post-harvest produce washing with various antimicrobials was conducted in study II. Specifically, spinach, tomatoes, green peppers and cucumbers were inoculated with S. Typhimurium and Tennessee or L. monocytogenes and washed in tap water, vinegar water (10%), lactic acid (5%), a lactic and citric acid blend (2.5%), and sodium hypochlorite (200 ppm) for 30 sec or unwashed. Vinegar water (10%) showed better (P<0.05) reduction of S. Typhimurium and Tennessee on tomatoes and cucumbers, and L. monocytogenes on tomatoes and peppers than tap water. The three antimicrobials reached an additional reduction level of 0.9 to 2.7 (S. Typhimurium and Tennessee) and 0.2 to 1.4 log CFU/g ( L. monocytogenes) compared to tap water. Lactic acid caused the greatest (P<0.05) reduction of S. Typhimurium and Tennessee on spinach and green peppers, and sodium hypochlorite showed the great (P<0.05) reduction of L. monocytogenes on cucumbers. The results supplied important information for FM vendors to develop post-harvest protocols to control foodborne pathogens.

Operability-Based Design Of Energy Systems: Application To Natural Gas Utilization Processes, Juan C. Carrasco-Moraga Jan 2017

Operability-Based Design Of Energy Systems: Application To Natural Gas Utilization Processes, Juan C. Carrasco-Moraga

Graduate Theses, Dissertations, and Problem Reports (ETD)

Process operability emerged in the last decades as a powerful tool for the design and control of complex chemical processes. The design of such processes is a challenging task as they are represented by nonlinear models with large numbers of differential and algebraic equations that demand high computational effort for their solution. In particular, process operability was proposed as a method for verifying the ability of a process design, defined by the available input set, to reach an achievable output set that considers production targets. However, existing operability methods for nonlinear systems are limited by the problem size that they …

Nonword Repetition Task To Evaluate Syllable Stress As A Motor Class, Emily R. Cobun Jan 2017

Nonword Repetition Task To Evaluate Syllable Stress As A Motor Class, Emily R. Cobun

Graduate Theses, Dissertations, and Problem Reports (ETD)

Current speech therapy methods and theories are based on generalized motor program (GMP) theory (Schmidt, 1975). GMP theory states a single GMP, or motor program, directs multiple movements of speech (Maas et al., 2008). Additionally, GMP theory asserts these similar muscle movements are part of the same motor class, which allows a GMP to direct performance on novel, untrained patterns of movements (i.e., what is termed "transfer performance"; Chamberlin & Magill, 1992; Schmidt, 1975). Alternatively, movements outside of a learned motor class will be more difficult to perform because a different GMP is controlling these movements. Currently, syllable stress patterns …

The Economic Benefits Of Portable Instrumentation On The Criminal Justice System: A Comprehensive Return-On-Investment Analysis, Korina Menking-Hoggatt

Graduate Theses, Dissertations, and Problem Reports (ETD)

Prosecuting crime is an expensive endeavor. This thesis compiles data from a variety of sources to show that, in 2015, the average cost of prosecuting a seized-drug case in the United States was about {dollar}26,000. Of that amount, crime laboratories only cost about {dollar}275 per seized-drug case, or less than ~1% of the total cost of prosecuting a drug case. We show that the criminal justice system could save millions of dollars per year by strategically investing in portable chemical instrumentation and conducting seized-drug confirmatory analyses at the scene of the crime, or at booking, instead of in the laboratory. …

Differential Response Policy And Child Maltreatment Re-Report, Amy A. Hunter Jan 2017

Differential Response Policy And Child Maltreatment Re-Report, Amy A. Hunter

Graduate Theses, Dissertations, and Problem Reports (ETD)

Child maltreatment is a serious public health issue. The decisions made by Child Protective Services (CPS) in response to reports of maltreatment may influence a child's risk of subsequent maltreatment. Studies have found a direct relationship between adverse childhood events (ACEs), (e.g., experiencing maltreatment, exposure to violence) and negative health outcomes across the lifespan (e.g., disease, developmental delays, suicidality, injury and death). Traditional CPS investigations focus on determining details of abuse events, and use that information to assess child safety and risk of future harm. The introduction of differential response policy provides supportive and preventive services to mitigate the risk …
