Characteristics Of Stocks And Individual Investor Herd Behavior: A Causal-Comparative Study, Tze Sun Wong

Walden Dissertations and Doctoral Studies

Some individual investors follow institutional investors in trading, a phenomenon called herding, that leads to excess market volatility and mispriced stocks. Individual investors who herded suffered from inferior investment performances and monetary losses, and the impact is broader in an individual investor dominant market such as Taiwan. Behavioral finance is the theoretical base of herd behavior. The purpose of this causal-comparative study was to examine individual investor herd behavior as related to characteristics of stocks in the Taiwan stock market. The research questions addressed what differences in individual investor herd behavior, if any, existed by market capitalization, price-to-book (P/B) ratio, …

Policy Implications Of News Media Coverage Of The Islamic State Of Iraq And Syria., Godfred A. Ababio

Walden Dissertations and Doctoral Studies

The Islamic State of Iraq and Syria (ISIS) garnered global news media attention in Summer 2014 when it seized a significant section of land in Iraq and Syria. The group then mishandled and executed its captives. There is a lack of consensus among the international community, led by Russia and the United States, on how best to address the threat posed by ISIS. An understanding of the function of Russian and U.S. news media coverage of the ISIS threat is an appropriate research topic. The purpose of this qualitative content analysis study was to explore how the U.S, Russian, and …

Leaders' Endorsement Of Idiosyncratic Workplace Fun, Organizational Playfulness Climate, And Organizational Creativity, Krasimir Karamfilov

Walden Dissertations and Doctoral Studies

Emotionally disconnected employees, about 70% in the U.S., do not experience positive affect at work, are disengaged, and not creative. The purpose of this quantitative quasi-experimental study was to investigate the effects of leaders' endorsement of idiosyncratic workplace fun (independent variable) and organizational playfulness climate (independent variable) on organizational creativity (dependent variable). Complexity-based theoretical perspectives on organizational creativity framed this quantitative study. Data were collected via three survey instruments at two data points from 7 project teams, divided into two experimental groups, at 6 companies in northwestern United States. One group received an intervention for 1 month. Pearson's correlation analysis …

Understanding The Perceptions And Decision-Making Behaviors Of First Responders In The Context Of Traumatic Events And Ptsd, Sunday O. Olatunji

Walden Dissertations and Doctoral Studies

Previous researchers have indicated that first responders are in an ever-changing environment, and unfortunately, the prevalence of post-traumatic stress disorder (PTSD) among first responders is increasing. This study sought to better understand first responders' perceptions of emergency preparedness protocols and training, as well as the prevalence of PTSD. This study also examined first responders' thoughts, decision making processes, and protective actions information, communications necessary during situations of emergency preparedness for traumatic events, and how PTSD impacted this process. A sample of 16 first responders of various ages was recruited for the purpose of this study. The participants were made up …

Native American Women Parenting Off Reservations: A Phenomenological Study, Xan.Creighton Beverley Creighton

Walden Dissertations and Doctoral Studies

For each parent, raising a child is a daunting task and it is even a harder undertaking for parents belonging to minority communities due to discrimination, and limited occupational and educational opportunities. Prior studies have shown high dropout rates from high school among Native American (NA) women, resulting in a lack of basic knowledge about raising children. The purpose of this research study was to synthesize, analyze, and better understand the lived experiences of NA mothers who are raising their children outside the reservation. This qualitative study relied on 4 theories: historical trauma theory, systems theory, acculturation theory, and strengths …

The Impact Of Depakote On Agitation And Short-Term Memory In Nursing Home Dementia Residents, Kristin E. Fazzolari-Pleace

Walden Dissertations and Doctoral Studies

Researchers have linked dementia to common psychiatric symptoms such as agitation and aggression, known as behavioral and psychological symptoms of dementia (BPSD). To treat residents manifesting BPSD, nursing homes (NHs) use psychoactive medications. However, research is limited and inconsistent regarding the impact of Depakote treatment on agitation and short-term memory (STM) in NH residents who have dementia. The purpose of this nonexperimental quantitative study was to evaluate for 1 year the impact of Depakote treatment on agitation and STM in NH residents as measured by each resident's Minimum Data Set (MDS). Moncrieff and Cohen's drug-centered theory served as the theoretical …

Anxious?: Re-Designing Women’S Jewelry To Help Manage Symptoms Of Anxiety Disorders, Nourbanu Feras Hijazi

Theses and Dissertations

Anxiety is a common and often stigmatized condition. Destigmatizing mental disorders can positively impact people’s interaction and communication with others and can prompt conversations in which people share their experiences with mental health, leading to improved societal understanding and perception.

My design solution tackles behavioral symptoms of anxiety, specifically two conditions that fall under obsessive-compulsive behavior: Dermatillomania and Trichotillomania. By redesigning women’s jewelry to specialized accessories, my intention is for these objects to help destigmatize these conditions and relieve symptoms of maladaptive behaviors and hurtful impulses. By redirecting these irresistible urges to an external artifact, the objects are designed to …

Exploring Burnout And Perceived Stress In Emergency Managers During Deployments, Angelika Phillips

Walden Dissertations and Doctoral Studies

The stressful nature of deploying to a disaster makes it necessary for a good emergency manager to be capable of coping in high-pressure situations. When intensified by extended work hours, deployments can often lead to burnout, job strain, and emotional stress, which can have a significant impact on an employee's well-being. The purpose of this study was to examine the effects of burnout and perceived stress amongst emergency managers working for FEMA and to determine if social support was an effective intervention. The theoretical foundation used for this study was the job demands-resources theory, which aided in understanding, explaining, and …

Counseling And Referral Experiences Of Southern Baptist Clergy, Charles Profit

Walden Dissertations and Doctoral Studies

Pastors are often called upon to counsel people troubled by what may be a diagnosable and treatable condition. Current research suggests that pastoral counselors (PC) are reluctant to provide a referral to a mental health professional (MHP) citing that only 10% of help seekers are referred, leaving millions of Americans to suffer with undiagnosed and untreated mental illness. The current literature indicates that PCs feel inadequately trained to counsel those with mental illnesses and the reluctance to refer is due to a distrust of MHPs. Currently, there is little qualitative research on pastors' counseling and referral experiences. In this study, …

Educational Manager Perceptions Towards Integrated Management Information System Implementation In Yemen, Mahfood Hussain Alkaabi

Walden Dissertations and Doctoral Studies

The government of Yemen has been developing government offered services designed to improve the quality of education management. Yemen's managers of education and managers of higher education in the Ministry of Education (MOE) and the Ministry of Higher Education (MOHE) have sought to improve quality of education, reduce costs, and provide timely information for decision-making processes by implementing an integrated management information system (IMIS). The problem was the lack of understanding the barriers that hinder successful IMIS implementation by the MOE and MOHE, and the role that lack of collaboration has played in prior unsuccessful attempts. The purpose of this …

Perspectives Of Mental Health Counselors Providing Care To Adults With Intellectual Disabilities, Cynthia Minto

Walden Dissertations and Doctoral Studies

Adults with intellectual disability (ID) experience twice the rate of mental health disorders when compared to the general population. Despite increased prevalence of mental health disorders, caregivers supporting adults with ID rarely seek mental health counseling supports, but instead are referred to psychiatric services. There is limited understanding among researchers about the lack of counseling services for adults with ID. The purpose of this study was to explore the lived experiences of mental health counselors who have worked with adults with ID in a counseling relationship. Hermeneutic phenomenology was used to develop thick and rick experiential detail about counselor experiences …

A Model For Seasonal Dynamic Networks, Jace D. Robinson

Browse all Theses and Dissertations

Sociotechnological and geospatial processes exhibit time varying structure that make insight discovery challenging. This paper presents statistical model of systems with seasonal dynamics, modeled as a dynamic network, to address this challenge. It assumes the probability of edge formations depend on a type assigned to incident nodes and the current time. Time dependencies are modeled by unique seasonal processes. The model is studied on several synthetic and real datasets. Superior fidelity of this model on seasonal datasets compared to existing network models, while being able to remain equally accurate for networks with randomly changing structure, is shown. The model is …

Blockchains have already been applied in spaces outside of finance, such as healthcare. This work explores the Bitcoin blockchain and a blockchain-based care coordination system through the use of modeling and simulation tools. Two agent based models are constructed: one to represent the Bitcoin blockchain, and a second to represent a blockchain-based care coordination system, MDChain. Insight is provided that is relevant to current issues within the Bitcoin community and predictions are made as to its future. The feasibility of …

Consequences Of Postsecondary Education Institution Policies And Practices: A Structural Model Of Tuition Costs, Student Financial Aid, Selectivity, Proximity, And Enrolled Undergraduate Students' Aggregate Capital, Aaron Michael Skira

Browse all Theses and Dissertations

For decades, U.S. higher education enrollments have been stratified with students from wealthier households consistently attending postsecondary institutions at higher rates than low-income students. The disparity in postsecondary participation rates by family income is a systemic issue (M. J. Bailey & Dynarski, 2011), meaning the phenomenon is the result of a combination of factors within society rather than one factor alone. Guided by a critical theory perspective and the assumptions behind Perna’s (2006) proposed conceptual model for student college choice research, the current study sought to examine the extent to which policies and practices at the postsecondary institution level may …

Abandoned By Home And Burden Of Host: Evaluating States' Economic Ability And Refugee Acceptance Through Panel Data Analysis, Ummey Hanney Tabassum

Browse all Theses and Dissertations

This research examines the relationship between the number of refugees hosted by states and the economic ability of host states by using UNHCR’s refugee data and World Bank’s GNI per capita data. To identify the relationship between these two variables, this study uses two sets of panel data covering 145-178 countries, around 43-55 years and 3000-5000 observations. For the two sets of panel data, four models are produced to test the null and alternative hypotheses. In all four cases, results show that there is a statistically significant negative correlation between the number of refugees hosted by states and GNI per …

Does “Evaluating Journal Quality And The Association For Information Systems Senior Scholars Journal Basket…” Support The Basket With Bibliometric Measures?, Alex Stewart, John L. Cotton

Management Faculty Research and Publications

We re-examine “Evaluating Journal Quality and the Association for Information Systems Senior Scholars Journal Basket…” by Lowry et al. (2013). They sought to use bibliometric methods to validate the Basket as the eight top quality journals that are “strictly speaking, IS journals” (Lowry et al., 2013, pp. 995, 997). They examined 21 journals out of 140 journals considered as possible IS journals. We also expand the sample to 73 of the 140 journals. Our sample includes a wider range of approaches to IS, although all were suggested by IS scholars in a survey by Lowry and colleagues. We also …

The Intersection Of Economic Disadvantage And Race And The Expanded Role Of Parent-Led School-Supporting Nonprofit Organizations In K-12 Public Schools In The Richmond, Virginia, Metropolitan Area: A Mixed Methods Approach, Rachel A. Levy

Theses and Dissertations

Nongovernmental actors have long been involved in the funding of U.S. K-12 public schools. With recent cuts to state funding to public education, however, groups called school-supporting nonprofits (Nelson & Gazley, 2014) have taken on a much larger role in school funding. Nonacademic, volunteer, parent-led groups such as parent teacher associations (PTAs), parent teacher organizations (PTOs), and booster clubs, especially, have grown in number and in amount of revenues raised, and are funding core school needs and functions. This situation confuses obligations of public institutions, undermines equity, and complicates the role of educational leaders. This mixed-methods study explores the influence …

Black Male Persistence In Spite Of Facing Stereotypes In College: A Phenomenological Exploration, Taylor Benjamin Hardy Boyd, Donald Mitchell Jr.

Faculty Publications

Stereotypes often create threatening environments for Black males on college campuses. This study sought to break the deficit narrative surrounding Black males in college by highlighting how they persisted despite facing stereotypes. Six participants were included in this study. Through interviews and naturalistic observations, we explored how participants articulated their experiences with stereotypes, how they dealt with those experiences, how the experiences shaped future endeavors, and how they used strategies to dispel stereotypes and persist through threatening experiences. Findings suggest (a) the participants dealt with internalized feelings due to stereotypes; (b) stereotypes were reinforced in various ways; and, (c) they …

Fragile X Syndrome And Family Occupations: Sertraline Treatment, Tracy Ye, Decerie Mendoza, Elena A. Javier, Martina C. Dualan

Student Research Posters

Current research on children with Fragile X Syndrome (FXS) lacks inclusion of qualitative outcomes on the child’s daily occupational performance. Standardized measurements are frequently utilized and provide useful information, however, can be less sensitive to change (Berry Kravis et al., 2013) and miss capturing family perspectives and improvements within meaningful occupations. This research incorporates family perspectives via semi-structured interviews to promote an in-depth understanding about FXS and its impact on child and family occupations in addition to standardized assessment scores through in-depth case study analysis. This study used a mixed method research design examining four male participants who were given …

Development Of An Integrated Service Model To Achieve Personal Health Libraries For Consumers, Nathan Gauss

Dissertations, Master's Theses and Master's Reports

This concept paper establishes the framework for additional research regarding how medical records are stored and shared. Health Information Technology is rapidly developing, and one large barrier to true interoperability is data silos. This integrated service model proposes using Health Record Banks (HRB) to store and share data, while using open source applications to limit costs and create opportunities for the consumer to be at the center of their own medical records. This includes the authorization phase, in which patients will be able to seamlessly allow access to their records for clinicians they choose. This conceptual framework includes using eXist …

Paid Parental Leave: An Investigation And Analysis Of Australian Paid Parental Leave Frameworks With Reference To Selected European Oecd Countries, Greg Lynn

Theses

xiii ABSTRACT In 2010, the Australian federal government introduced a national scheme of taxpayer-funded paid parental leave. This legislation was introduced only after much political debate and came after more than 100 years of reform to Australian industrial law to make employment laws work better for employees with families. These reforms occurred on the back of a long history of relatively slow female legal emancipation in Australia and the concept of employment rights for women having children is a relatively new legal concept. Australian employment law has traditionally been conceptualised in terms of the paradigm of ‘the male breadwinner,’ supported …

Attributions Online: An Examination Of Time Stamps, Read Receipts, And Ellipses In Text-Based Communication, Kelsey Kathleen Earle

Communication

According to social information processing theory (SIPT), humans are actively encoding and decoding information when communicating through technology (Walther, 1992). This study uses SIPT as a theoretical guideline and examines the type of attributions formed when elements such as time stamps, read receipts, and ellipses are present in text-based communication. Malle’s (2006) categorization of attribution types was used to analyze attributions from a free response section of an online experiment. Various chi-square tests were used to determine if attributions differed when various chronemic cues were present. Only one hypothesis was supported, but results provide opportunities for future research in this …

Economic Efficiency Of Occupational Health And Safety Investments At Agricultural Cooperatives, Thilani Kaushalya Wearaduwa Vidana Kankanamge

Agribusiness and Applied Economics

Industries related to agricultural cooperatives record some of the highest injury rates in the U.S. Therefore, agricultural cooperatives are highly motivated to invest in occupational health and safety (OHS). This thesis examines the economic efficiency of OHS investments at agricultural cooperatives and identifies cooperative characteristics leading to greater economic efficiency of OHS investments. A multiple input-output data envelopment analysis (DEA) is used to estimate technical efficiency. The effects of cooperative characteristics on the efficiency of OHS investments are estimated using ordinary least squares, censored regression, truncated regression, and the Simar and Wilson (2007) bootstrap procedure. Results show that the mean …

Case Study Of The Gold King Mine Spill, Erica Elizabeth Black

Emergency Management

The Gold King Mine spill happened on August 5, 2015 near Silverton, Colorado when the abandoned mine was damaged during maintenance. This single, holistic exploratory case study uses document review and analysis to answer the research questions of what happened at Gold King Mine, how and why it happened, what was the response, and what are the implications of this event. The findings indicate that the Environmental Protection Agency’s negligence, Colorado’s lack of regulations on abandoned mines, and the town of Silverton’s hesitance to be declared a Superfund site all contributed to the water contamination which negatively impacted the Navajo …

Arbitration, What Is It Good For?, Thomas O. Main

Nevada Law Journal

In the lead piece of this symposium, Hensler and Khatam bring into relief two paradoxes in contemporary arbitration policy and practice.1 First, arbitration is beset by hyperspecialization into segmented domains, yet is plagued by reforms that transcend those boundaries. Second, arbitration seeks all the virtue of formal adjudication without the process, yet process is the principal virtue of formal adjudication.

Hensler and Khatam invite readers to think broadly about contemporary arbitration policy and practice. Accepting that invitation, I briefly explore four areas of inquiry that can be reduced to the interrogatives Why?, What?, When?, and Who?, respectively. All four questions …
