Trading Volume And Overconfidence With Differential Information And Heterogeneous Investors, Kenneth Yung, Qian Sun, Hamid Rahman

Finance Faculty Publications

This paper adds to the overconfidence literature by specifically considering the differential nature of information and its use by different classes of investors. The literature suggests that overconfidence is a major determinant of stock trading volume. We postulate that private investors are more prone to overconfidence bias as compared to institutional investors. This implies that turnover in firms with low institutional ownership will be driven more by private information while turnover in firms with high institutional ownership will be driven more by public information. This is the essence of the two hypotheses we explore. We find strong evidence in support …

STEMPS Theses & Dissertations

The purpose of this study was to determine if a unique set of Knowledge, Skills, and Abilities (KSAs) were required of Human Resource Practitioners (HRPs) in federal-level Government Contracting Companies (GCC) in the United States. Study results identified additional sets of HR-related KSAs to perform with minimum competency within a government-contracting environment. The results of this study can assist in creation and development of training or education curriculum for HRPs interested in or currently working in GCCs. Study results provided parameters for job descriptions for HRP recruitment within GCCs and HRP promotional opportunities.

Transition From High School To Associate Degree Nursing Education: A Qualitative Study, Kathy Jessee Mitchell

Educational Leadership & Workforce Development Theses & Dissertations

Nursing is facing a critical shortage and retention of nursing students is of paramount importance. Much research has been completed related to retention in nursing education and student success, but there is very little in current literature related to issues associated with the transition from high school to associate degree nursing (ADN) education. The purpose of this study was to explore this phenomenon through qualitative research involving ADN students who entered the nursing programs immediately after graduation from high school. This qualitative study involved students from a rural associate degree program. The intent was to provide a better understanding of …

Two Essays On Behavioral Finance, Quang Viet Vu

Theses and Dissertations in Business Administration

The first essay is entitled: "CEO Overconfidence, Corporate Governance Practices and Firm Innovation". In this study, I examine if overconfident CEOs overinvest or underinvest in innovative projects. I also investigate if overconfident CEOs pursue innovative projects to benefit personal interests or the interest of shareholders. By focusing on the effect of corporate governance in monitoring the behavior of overconfident CEOs, my results show that there is a negative relation between CEO overconfidence and firm innovation among firms with poor governance. In these cases, the finding is consistent with the implication that overconfident CEO are entrenched and invest inadequately …

A Phenomenological Study Of The Experiences Of Women In Leadership And Community At Old Dominion University From 1970 To 1990, Ann E. Wendle Barnes

Educational Leadership & Workforce Development Theses & Dissertations

During the 1970s college campuses in the United States were often the venue through which change occurred. Female faculty and students were assertive in their efforts to influence equality between men and women across the country (Morris, 1984). This historical phenomenological study examined the oral history of several women who advocated for women's rights at Old Dominion University (ODU) by establishing the Women's Caucus, Women's Studies Program, and Women's Center during the late 1970s through the 1990s.

Participants selected for this study took part in semi-structured interviews, and the results of the interviews were triangulated with archived documents available at …

Optimizing Chronic Slow Breathing Training To Cause A Therapeutic Effect On Heart Rate Variability, Jennifer Joy Brown

Human Movement Studies & Special Education Theses & Dissertations

Heart rate variability (HRV) is a valid and reliable tool that can be used to determine the basic state of an individual's autonomic health. The current study attempted to establish the minimum frequency of breathing practice necessary to produce a therapeutic effect on HRV over the course of a four-week period with four different treatment groups, specifically, groups that practiced a slow breathing protocol for either 2, 3 or 5 times per week, and a control group. Forty-three subjects (14 males, 29 females), ages 18–50 years, were screened, pre-tested, matched for sex, age and HRV, assigned to a specific group …

The Expected Adjustment And Academic Outcomes Of Honors College Students, Christina R. Washington

Counseling & Human Services Theses & Dissertations

The transition to an institution of higher education can present challenges and difficulties, but it is a student's expectations that can ultimately predict adjustment (Jackson, Pancer, Pratt, & Hunsberger, 2000). A larger number of students who experience difficulties in their adjustment end up withdrawing from the institution (Baker & Siryk, 1986). There is evidence that for some students there is a vast disconnect between their expectations regarding the institution of higher education, and the reality of their experiences. Students may not realize that what was expected of them in high school will differ greatly in college. It is this lack …

The Impact Of Teacher Licensure Programs On Minority Student Achievement, Rose S. Duke

Educational Leadership & Workforce Development Theses & Dissertations

This research examined the impact of teacher licensure routes, particularly those identified as either traditional or alternative on student achievement by comparing Virginia Standards of Learning (SOL) end of year scores in math and reading for minority students in grades six through eight during the period from 2005 through 2009. To compare the achievement of students taught by either traditionally or alternatively prepared teachers, the Standards of Learning (SOL) scores were calculated for students and then aggregated for types of teacher preparation. The mean values were compared for statistically significant differences as a function of subject, teacher ethnicity, teacher gender, …

A Framework For Delivering Contextually Appropriate Opportunities For Warfighter Practice, Michael Allan White

Computational Modeling & Simulation Engineering Theses & Dissertations

Computer-based modeling and simulation has been a training staple in the military domain since the first aircraft simulators were adopted. More recently, virtual environments based on modeling, simulation and serious games, have introduced relatively low-cost, yet high value additions to the learning environment. As these virtual environments have proliferated, many researchers have investigated the relationship between theoretical foundations of learning, learner development and content delivery, and applied their findings in an attempt to bolster learning, yet performance deficiencies continue to exist. This study asserts that performance deficiencies exist in part because of insufficient contextually appropriate opportunities to practice.

STEMPS Theses & Dissertations

The purpose of this study was to determine factors female higher education faculty in select science, technology, engineering, and mathematics (STEM) fields perceived as influential to their success and persistence in their chosen professions. Females are underrepresented in STEM professions including academia, despite the fact that female educational attainment in all fields have increased significantly.

Four research questions were used to guide this study and they are: 1) What personal factors affect females' ability to successfully persist in STEM faculty positions? 2) What social factors affect females' ability to successfully persist in STEM faculty positions? 3) What academic/institutional factors affect …

Using The Counseling Center Assessment Of Psychological Symptoms - 34 (Ccaps-34) To Predict Premature Termination In A College Counseling Sample, Sean B. Hall

Counseling & Human Services Theses & Dissertations

Swift and Greenberg (2012) observed that variables influencing the decision to drop out fluctuate according to the primary presenting problem, the amount of structure in therapy, the length of treatment, and the clinical setting. Due to these reports, researchers may focus on predictors of premature termination (PT) in treatment settings where the unique situational characteristics may have an idiosyncratic influence on the decision to withdraw from services (Phillips, 1985; Swift & Greenberg, 2012). The purpose of this exploratory study was to examine client characteristics that impact dropout in University Based Clinics (UBC). Results from the logistic regression analysis indicated higher …

Dispositions In The Twenty First Century School Library Profession, Sue C. Kimmel, Gail K. Dickinson, Carol A. Doll

STEMPS Faculty Publications

Within the school library profession there is an emerging focus on dispositions, defined as "a tendency to exhibit frequently, consciously, and voluntarily a pattern of behavior that is directed to a broad goal" (Katz, 1993). Directed focus groups of practicing school librarians were asked to articulate their vision for school libraries of the future. Data from these groups informed development of six dispositional continua to guide both school library education and school librarianship in the 21st century. This study clarifies the dispositions needed by school librarians in the future.

Self-Injury And Eating Disorders In Minors: When Should The Human Service Professional Break Confidentiality?, Laurie Craigen, Rebekah Cole

Counseling & Human Services Faculty Publications

The decision to protect or breach confidentiality is a common ethical dilemma for human service professionals. This decision is further complicated when the client is a child or adolescent. This manuscript examines the issue of confidentiality and minors with two common harmful behaviors in adolescents: self-injury and eating disorders. A continuum of physical and psychological factors are included to help the human service profession in ethical decision making. Two case studies followed by a list of questions to use in the decision making process are also provided.

Training Evaluation In Virtual Worlds: Development Of A Model, Richard N. Landers, Rachel C. Callan

Psychology Faculty Publications

Many organizations have adopted virtual worlds (VWs) as a setting for training programs; however, research on appropriate evaluation of training in this new setting is incomplete. In this article, we address this gap by first exploring the unique issues relevant to evaluation faced by training designers working in VWs. At the macro-organizational level, the primary issue faced is an organizational culture unreceptive to or otherwise skeptical of VWs. At the micro-organizational level, two major issues are identified: individual trainees unreceptive to VWs and general lack of experience navigating VWs. All three of these challenges and their interrelationships may lead to …

Drinking Buddies And Their Prospective Influence On Alcohol Outcomes: Alcohol Expectancies As A Mediator, Cathy Lau-Barraco, Abbly L. Braitman, Kenneth E. Leonard, Miguel Padilla

Psychology Faculty Publications

The process by which peers or the social network influence individual alcohol use, particularly among adults, remains a necessary area of research. The purpose of the present study was to examine the longitudinal influence of "drinking buddies" on alcohol outcomes (i.e., alcohol use, heavy drinking, and alcohol-related problems) as mediated by alcohol expectancies of social facilitation. Participants were 1347 (men = 660, women = 687) newly married individuals recruited from the community. They were assessed at the time of marriage and through the fourth wedding anniversary. Longitudinal mediation across time was evaluated using latent growth modeling. Overall, the prospective association …

Investigating Insight As Sudden Learning, Ivan K. Ash, Benjamin D. Jee, Jennifer Wiley

Psychology Faculty Publications

Gestalt psychologists proposed two distinct learning mechanisms. Associative learning occurs gradually through the repeated co-occurrence of external stimuli or memories. Insight learning occurs suddenly when people discover new relationships within their prior knowledge as a result of reasoning or problem solving processes that re-organize or restructure that knowledge. While there has been a considerable amount of research on the type of problem solving processes described by the Gestalt psychologists, less has focused on the learning that results from these processes. This paper begins with a historical review of the Gestalt theory of insight learning. Next, the core assumptions of Gestalt …

Pathways To Early Coital Debut For Adolescent Girls: A Recursive Partitioning Analysis, Matthew R. Pearson, Tatyana Kholodkov, James M. Henson, Emily A. Impett

Psychology Faculty Publications

This study examined pathways to early coital debut among early to middle adolescent girls in the United States. In a two-year longitudinal study of 104 adolescent girls, recursive partitioning (RP) analyses were conducted to examine the specific factors that were related to engaging in first intercourse by the 10th grade among adolescent girls who had not yet engaged in sexual intercourse by the 8th grade. RP analyses identified subsamples of girls who had low, medium, and high likelihoods of engaging in early coital debut based on six variables (i.e., school aspirations, early physical intimacy experiences, depression, body objectification, body image, …

Are Low Wages Risk Factors For Hypertension?, J. Paul Leigh, Juan Du

Economics Faculty Publications

Objective: Socio-economic status (SES) is strongly correlated with hypertension. But SES has several components, including income and correlations in cross-sectional data need not imply SES is a risk factor. This study investigates whether wages-the largest category within income-are risk factors. Methods: We analysed longitudinal, nationally representative US data from four waves (1999, 2001, 2003 and 2005) of the Panel Study of Income Dynamics. The overall sample was restricted to employed persons age 25-65 years, n = 17 295. Separate subsamples were constructed of persons within two age groups (25-44 and 45-65 years) and genders. Hypertension incidence was self-reported based on …

Aging, Neuromuscular Decline, And The Change In Physiological And Behavioral Complexity Of Upper-Limb Movement Dynamics, S. Morrison, K. M. Newell

Rehabilitation Sciences Faculty Publications

Aging is characterized by a general decline in physiological and behavioral function that has been widely interpreted within the context of the loss of complexity hypothesis. In this paper, we examine the relation between aging, neuromuscular function and physiological-behavioral complexity in the arm-hand effector system, specifically with reference to physiological tremor and isometric force production. Experimental findings reveal that the adaptive behavioral consequences of the aging-related functional decline in neurophysiological processes are less pronounced in simple motor tasks which provides support for the proposition that the motor output is influenced by both extrinsic (e.g., task related) and intrinsic (e.g., coordination, …

Three Essays On Strategic Risk Taking, Krista Burrill Lewellyn

Theses and Dissertations in Business Administration

The three essays that comprise this dissertation collectively explore strategic risk taking. The dissertation is underpinned by the notion that corporate executives take strategic risks not randomly, but based on the expectation that outcomes are more likely to be positive rather than negative. Each essay examines how and why decision makers come to vary in their cognitive evaluation of the acceptability of strategic risk taking.

Essay 1 draws from the approach/inhibition theory of power, to explore how power not only provides the means for CEOs to exert their risk preferences, but actually affects what the risk preferences are. Power is …

An Examination Of Factors Affecting Non-Urgent Use Of Emergency Department Services By Patients With "Universal" Healthcare, Gregory Smith Feltenberger

Health Services Research Dissertations

The purpose of this research is to examine the factors affecting non-urgent utilization of emergency department (ED) services by individuals with "universal" healthcare using the Behavioral Model of Health Services Use. Since Air Force Medical Service beneficiaries have free and unlimited use of the full-range of healthcare services, they are ideally suited for this study. The findings of this research may also apply to other populations with free or low-cost access to healthcare (i.e., universal or single-payer healthcare). Using secondary data extracted from the Air Force Medical Service's electronic health record system at several military hospitals, this study will present …

Intimate Partner Physical Violence Against Women In Saudi Arabian Primary Healthcare Clinics, Halah M. Eldoseri

Health Services Research Dissertations

Intimate partner violence against women (IPPVAW) is a serious public health concern. The Ecological Model provides a model to study several factors associated with IPPVAW. In Saudi Arabia, studies addressing IPPVAW are limited and do not cover the various aspects of the problem. The purpose of this study was to investigate the various factors associated with IPPVAW at the personal, interpersonal, community and societal levels. Methods: 200 ever-married women attending six PHC in Jeddah, Saudi Arabia were recruited via convenient sampling method. Women were interviewed on factors related to IPPVAW using an adapted version of WHO survey for violence against …

Model Individualization For Real-Time Operator Functional State Assessment, Guangfan Zhang, Roger Xu, Wei Wang, Aaron A. Pepe, Feng Li, Jiang Li, Frederick Mckenzie, Tom Schnell, Nick Anderson, Dean Heitkamp

Electrical & Computer Engineering Faculty Publications

Proper assessment of Operator Functional State (OFS) and appropriate workload modulation offer the potential to improve mission effectiveness and aviation safety in both overload and under-load conditions. Although a wide range of research has been devoted to building OFS assessment models, most of the models are based on group statistics and little or no research has been directed towards model individualization, i.e., tuning the group statistics based model for individual pilots. Moreover, little emphasis has been placed on monitoring whether the pilot is disengaged during low workload conditions. The primary focus of this research is to provide a real-time engagement …

A Systematic Approach For Real-Time Operator Functional State Assessment, Guangfan Zhang, Wei Wang, Aaron Pepe, Roger Xu, Tom Schnell, Nick Anderson, Dean Heitkamp, Jiang Li, Feng Li, Frederick Mckenzie

Electrical & Computer Engineering Faculty Publications

A task overload condition often leads to high stress for an operator, causing performance degradation and possibly disastrous consequences. Just as dangerous, with automated flight systems, an operator may experience a task underload condition (during the en-route flight phase, for example), becoming easily bored and finding it difficult to maintain sustained attention. When an unexpected event occurs, either internal or external to the automated system, the disengaged operator may neglect, misunderstand, or respond slowly/inappropriately to the situation. In this paper, we discuss an approach for Operator Functional State (OFS) monitoring in a typical aviation environment. A systematic ground truth finding …

A Voice-Based Automated System For Ptsd Screening And Monitoring, Roger Xu, Gang Mei, Guangfan Zhang, Pan Gao, Timothy Judkins, Michael Cannizzaro, Jiang Li, James D. Westwood (Ed.), Susan W.

Electrical & Computer Engineering Faculty Publications

Comprehensive evaluation of PTSD includes diagnostic interviews, self-report testing, and physiological reactivity measures. It is often difficult and costly to diagnose PTSD due to patient access and the variability in symptoms presented. Additionally, potential patients are often reluctant to seek help due to the stigma associated with the disorder. A voice-based automated system that is able to remotely screen individuals at high risk for PTSD and monitor their symptoms during treatment has the potential to make great strides in alleviating the barriers to cost effective PTSD assessment and progress monitoring. In this paper we present a voice-based automated Tele-PTSD Monitor …

Evacuee Route Choice Decisions In A Dynamic Hurricane Evacuation Context, R. Michael Robinson, Asad Khattak

VMASC Publications

Very high traffic volumes may lead to extensive congestion during hurricane evacuations. Evacuation planners reduce this congestion by careful planning for multiple hurricane scenarios and assignment of evacuation routes and timing. This planning may be for naught if obstructions block key roadways. An advanced traveler information system (ATIS) may be used to guide evacuees to alternate routes, but how effective will that guidance be? Should the use of alternate routes be encouraged? How are drivers likely to respond to delays and information? Will information shorten or improve the reliability of travel times in emergency conditions? Integration of a dynamic evacuation …

The Influence Of Late Registration On Academic Outcomes And Retention At A Multi-Campus Community College, Kathy John Maalouf

Counseling & Human Services Theses & Dissertations

In response to the increasing challenge for community colleges to uphold their mission of accessibility with an open door policy, while being held accountable for student success, higher education administrators and counselors need to have a better comprehension on the relationship among community college students, institutional enrollment policies, and academic success. The overall purpose of study was to broaden the understanding of the implications of late registration policy on community college students. Specifically, the purpose was to (1) investigate if there are statistical relationships between the demographics of community college students, registration behaviors, academic outcome, and retention (2) identify possible …

The Influence Of Teacher Preparation Programs' Field Experiences On Pre-Service Teacher Candidates' Sense Of Teaching Efficacy, Alison Marie Reddy

Teaching & Learning Theses & Dissertations

In this descriptive, mixed methods study, the researcher investigated the influence of teacher preparation programs' field experiences on teacher candidates' sense of teaching efficacy. Tschannen-Morgan & Woolfolk-Hoy's (2001) Teacher Sense of Efficacy Scale questionnaire was sent to 221 teacher candidates enrolled in one of five teaching license paths in a large metropolitan university in the eastern part of the United States. Seventy-seven percent of the questionnaires were returned. Questionnaires were analyzed to determine the degree the number of hours of elementary teacher candidates' field experiences influence their perceptions of their teaching efficacy. The questionnaires were also used to compare the …
