Management control research has often focused on finding the right fit between management control systems and the unique situational context of organizations, but few studies have examined the role of individual personality traits. Therefore, the purpose of this study was to provide a better understanding about the relationship between the Big Five personality traits, management control systems and organizational commitment. We addressed the research gap regarding how the interaction between the Big Five personality traits and management control systems may affect organizational commitment. To answer the research questions, data was collected using a web survey, which was analyzed in statistical software. In total, 103 responses from managers across 30 Swedish companies, were obtained. Our findings indicate that the interaction of the personality trait conscientiousness and results control, and the interaction of the personality trait agreeableness, and cultural control may affect organizational commitment. Based on these findings, theoretical and practical implications are discussed.

The purpose of this study was to investigate the perceived impact of spiritual consciousness on leadership performance. The assumptions of several leadership theories were discussed in relation to spirituality and performance. The leadership qualities associated with performance were highlighted and evaluated. The present study was conducted with ten high performing leaders of private-sector organisations in Johannesburg, South Africa. Qualitative analysis of quantitative and qualitative data was performed. Psychometric assessment results were interpreted and evaluated, semi-structured interviews were conducted and 360 degree questionnaires were administered with the intent to evaluate leadership behaviours impacting on performance. The first part of the interview consisted of a section allowing the participant to tell a story of how their career developed over time. The second part of the interview contained questions pertaining to leadership, the qualities, characteristics and behaviours of successful leaders and those qualities and characteristics that have resulted in their own success followed by questions pertaining to the participant’s perception of spirituality, their experience of spirituality and the perceived link to performance, and lastly their view on spiritual leadership and the impact thereof on performance. The findings suggest that leaders who demonstrate spiritually conscious behavioural traits will likely be regarded as high performing leaders. The relationship between spiritual consciousness and leadership performance was described in detail and recommendations were made for the the implementation of a spiritual consciousness model in the selection of leaders. Confirmative empirical studies with a larger sample are needed to support the findings and to further explore this interesting phenomenon. / Psychology / Ph. D. (Consulting Psychology)

To evaluate the effectiveness of the West Virginia Prescription Drug Abuse Quitline (WVPDAQ). Descriptive data and inferential analyses are provided for the period of operations from 9/11/2008 to 3/1/2010. Chi-square tests for Independence compared differences between callers completing at least one follow-up survey against callers completing only the baseline intake survey were observed. A Wilcoxon signed rank sum test tested differences between the scores of intake callers and follow-up callers at the one-week (n = 177) and one-month (n = 89) intervals. A total of 1,056 calls were received, including 670 intakes, 177 1st follow-ups, 89 2nd follow-ups, and 36 3rd follow ups, and 84 caller satisfaction surveys. Chi-square analyses determined that callers who only completed the intake survey tended to have initiated drug use at a younger age (< or = 39 years of age, chi2 = 7.63, p = .02). Longitudinal findings indicated significant self-reported declines in daily drug use (p < .0001), increased intentions to quit in the next 30 days (p < .0001), and declines in requesting a referral for treatment (p < .0001) at the one-month follow-up. Finally, approximately 19% (n = 17) of callers reported obtaining a counseling/ treatment appointment as a result of calling the WVPDAQ at the one-month follow up. Preliminary results suggest the WVPDAQ has established itself as a meaningful resource to combat prescription drug abuse in West Virginia. Sustainable funding and greater integration of the WVPDAQ into existing and developing treatment infrastructure could provide more affordable options for the state of West Virginia and its citizens.

<div>Mixing of stratified fluids due to motion of bubble swarms can happen through two major mechanisms. The first is the capture and transport of heavier liquid into the lighter layers by the bubble wake. The second is the mixing due to turbulent dispersion. Stratification also affects bubble dynamics in various ways, namely by reducing the horizontal and vertical bubble fluctuations and extent, altering the drag experienced by rising bubbles, and changing the wake dynamics. The objective of this study is to understand these explained phenomena by decoupling their effects from each other and studying them individually. CFD offers powerful capabilities to achieve the decoupling and perform in-depth analysis of the fluid flow. </div><div><br></div><div>Firstly, the study of mixing induced in stratified fluids by bubbly flow in a Hele-Shaw Cell will be performed. Simulations are run for a range of void fractions and Froude numbers. The confinement prevents turbulence production, and mixing occurs primarily due to transport of colder liquid into the hotter layers by the bubble wake. Bubbles move in a zigzag motion attributed to the periodic vortex shedding in their wake. We report the formation of horizontal clusters and establish a direct correlation between the size of clusters and the rise velocity of the bubbles. We report an increase in the buoyancy flux across the isopycnals as the void fraction increases. The fraction of energy production due to the buoyancy flux increases with the strength of stratification, giving rise to a higher mixing efficiency. At the same time, cross isopycnal diffusion is higher at weaker stratification strengths.</div><div><br></div><div>Subsequently, direct numerical simulations of up to 146 bubbles rising in unbounded stratified fluids are performed. Both the bubble dynamics and destratification effects caused by the bubble motion are analyzed. The importance of bubble deformability and bubble Reynolds numbers on the induced background mixing are studied by varying the $E\ddot{o}tv\ddot{o}s$ number in the range 1.55 to 4.95 and Reynolds number in the range 25 to 200. Highly deformable, high Reynolds number bubbles undergo path instabilities and give rise to higher levels of mixing. Liquid and bubble velocity fluctuations and pseudo-turbulence caused by the bubble motion in the unconfined setting are examined and are seen to play an important role in mixing statistics. An increase in turbulent kinetic energy (TKE) levels with void fraction is noted. TKE levels are seen to decrease slightly as the stratification strength is increased, indicating increasing stability and resistance to destratification. Regardless of the stratification strength, a kinetic energy spectrum slope value between $-3 \sim -3.25$ is reported depending on Reynolds number. The dependence of mixing parameters on the void-fraction of bubbles and stratification strength of the liquid is also presented. </div><div><br></div><div>Next, the study of buoyancy driven motion of a single air bubble in stratified liquid is undertaken. A range of parameters including Froude number, Reynolds number and Bond number are explored. The Reynolds and Bond numbers will be maintained at values where the bubble motion and wake can be assumed to be axisymmetric. Wake dynamics and drift-volumes associated with the bubble rising in the stratified fluid are analyzed. The presence of secondary and tertiary vortices, which are alternating in direction, in the wake of the bubble due to the negative buoyant force experienced by the isopycnals is reported. The isopycnals oscillate before coming back to their stable state and the frequency of oscillations increases with stratification strength. The dependence of drag coefficient, determined by an unsteady force balance, and steady state bubble velocities, on the above mentioned parameters are studied. Analysis of bubble rise in partial stratification reveals the differences between homogeneous and stratified mediums.</div><div><br></div><div>Since most stratified bubbly flows occur near the free surface, an attempt is made at modeling the bubble rise up-to the free surface and subsequent bubble bursting. A brief study of in-line bubble coalescence is also attempted and potential future work for bubbly flows with topological changes is discussed.</div>

Introduction: Lymphoepithelial carcinoma (LEC) in the oropharynx is rare. Current understanding of the disease is derived mainly from case reports and small case series, prompting further elucidation of its epidemiology and prognostic factors that affect outcome. The aim of this retrospective cohort study was to examine demographic characteristics, clinicopathologic features, and prognostic factors in patients with oropharyngeal LEC. Methods: The U.S. National Cancer Institute’s SEER registry was queried to obtain data on patients with primary oropharyngeal LEC from 1975 to 2016. Variables examined include age at diagnosis, sex, race, year of diagnosis, primary site of tumor origin, tumor size, extent, nodal status, overall stage, tumor grade, surgical treatment, and county socioeconomic status (SES). Kaplan-Meier univariable and Cox regression model multivariable analyses were conducted to identify independent predictors of survival. Results: In total, 199 cases of primary LEC in the oropharynx were found. Overall survival rates at 2-, 5-, and 10-years were 81.0%, 74.0%, and 56.0%, respectively. Disease-specific survival rates at 2-, 5-, and 10-years were 85.0%, 80.0%, and 77.0%, respectively. Multivariable analysis identified older age at diagnosis, Black race, and tonsil primary site to be independent predictors of worse survival. Contrarily, a more recent year of diagnosis, surgical resection, and higher county SES were identified to be associated with an improved prognosis. Conclusion: Oropharyngeal LEC is a rare malignancy that is diagnosed mostly in White males in the fifth decade of life. Patient age, race, year of diagnosis, primary site of tumor origin, surgical treatment, and county SES were found to significantly affect survival. Although oropharyngeal LEC is associated with a relatively favorable prognosis, detecting disease early and including surgical resection in treatment may aid in further improving survival.

The revised Stanford-Binet Intelligence Scale probably is the best instrument we now have for measuring the general intelligence of young people. Using this scale we can foretell to a large degree a child's future mental growth; and with this knowledge as an important part of the total knowledge needed for prediction, we can more scientifically plan his further education and his vocational choice.

We introduce the Partition Principle PP, an axiom introduced by Russell in the context of its similarities and differences with the Axiom of Choice AC. We start by proving some properties of PP, and AC, and show that AC, entails PP. To address the problem of whether the converse holds, we develop the Zermelo-Fraenkel ZF set theory and examine its consistency and build a model in which AC, fails. We follow this with a discussion of forcing, a technique introduced by Paul Cohen to build new models of set theory from existing ones, which have differing properties from the starting model. We conclude by examining candidate models called permutation models where AC, fails, which may be useful as candidate models for forcing a model in which PP, holds but AC, does not. We conjecture that such a model exists, and that PP, does not entail AC. / Thesis / Master of Science (MSc)

In recent years, questions have risen regarding the language used to describe those who are supervised by the criminal justice system, participating in mental health services, and examined in research. This has resulted in recommendations to reduce labelling bias, as is evident from the recent editions of the APA Publication Manual (2009, 2019), editorials (Willis & Letourneau, 2018), and ethics discussions (Willis, 2018). In 2016, the United States Department of Justice adopted a policy of referring to their detainees and supervisees using person-first language, such as “individual who has offended,” rather than referring to individuals based on the nature of their offenses. With these developments, recent research has increased our focus on the way professionals identify those involved in the criminal justice system, how our labels impact these individuals, and the sociocultural implications of our language use (e.g., Denver, Pickett, & Bushway, 2017). The poster presents preliminary results of the sexual abuse terminology project, which examines professionals’ use of language to identify and describe individuals who have engaged in sexually abusive behaviors, the sexually abusive behaviors themselves, and sexual interests associated with abusive behavior, between 1981 and 2020. This poster will specifically highlight person identifiers across five-year intervals from 1981 through 2015 (as data collection from publications in 2020 will still be ongoing at the time of presentation), demonstrating trends is language use over time. For this analysis, 1,223 peer-reviewed studies were evaluated for language use. Eighty-three label categories (e.g., abusers, individuals, offenders, etc.) were identified, with 410 specific labels (e.g. intrafamilial child sexual abusers, men with sexual behavior problems, deviant patients, etc.) identified in total. While “offender” labels are the most consistently used terms across all years, trends in term use over time will be presented across five-year intervals. Trends in terminology usage will be graphically depicted, and hypotheses for changes in terminology used will be discussed.
