Variation And Efficiency Of High-Frequency Betas, Congshan ZHANG, Jia LI, Viktor TODOROV, George. TAUCHEN 2022 Singapore Management University

Variation And Efficiency Of High-Frequency Betas, Congshan Zhang, Jia Li, Viktor Todorov, George. Tauchen

Research Collection School Of Economics

This paper studies the efficient estimation of betas from high-frequency return data on a fixed time interval. Under an assumption of equal diffusive and jump betas, we derive the semiparametric efficiency bound for estimating the common beta and develop an adaptive estimator that attains the efficiency bound. We further propose a Hausman type test for deciding whether the common beta assumption is true from the high-frequency data. In our empirical analysis we provide examples of stocks and time periods for which a common market beta assumption appears true and ones for which this is not the case. We further quantify ...

How Is Health Seeking Behavior And Patient Outcomes For Latin Immigrants Affected By Language Barriers, Socioeconomic Status And Health Literacy?, Cassandra Sanchez 2022 Dominican University of California

How Is Health Seeking Behavior And Patient Outcomes For Latin Immigrants Affected By Language Barriers, Socioeconomic Status And Health Literacy?, Cassandra Sanchez

Nursing | Senior Theses

Background

Language barriers cause a disconnect between patients and health care workers. What further causes a disconnect is when patients have a lower level of education in addition to having a language barrier. I will be focusing on Latin immigrant individuals in the United States for my research. Many Latin immigrant patients may not have gone to school in their native countries, so their education level is lower making it harder to understand discharge information or patient teaching. When patients are unable to have that health literacy it may lead to negative patient outcomes due to not adhering to medication ...


Developing A Lifestyle Intervention Program For Overweight Or Obese Preconception, Pregnant And Postpartum Women Using Qualitative Methods, Chee Wai KU, Shu Hui LEOW, Lay See ONG, Christina ERWIN, Isabella ONG, Xiang Wen NG, Jacinth Jia Xin TAN, Fabian YAP, Jerry K. Y. CHAN, See Ling LOY 2022 Singapore Management University

Research Collection School of Social Sciences

The time period before, during and after pregnancy represents a unique opportunity for interventions to cultivate sustained healthy lifestyle behaviors to improve the metabolic health of mothers and their offspring. However, the success of a lifestyle intervention is dependent on uptake and continued compliance. To identify enablers and barriers towards engagement with a lifestyle intervention, thematic analysis of 15 in-depth interviews with overweight or obese women in the preconception, pregnancy or postpartum periods was undertaken, using the integrated-Promoting Action on Research Implementation in Health Services framework as a guide to systematically chart factors influencing adoption of a novel lifestyle intervention ...


The View From Somewhere: Institutional Values In Collections Decisions, Heather A. Howard, David Zwicky, Danielle Walker 2022 Purdue University

The View From Somewhere: Institutional Values In Collections Decisions, Heather A. Howard, David Zwicky, Danielle Walker

Libraries Faculty and Staff Presentations

As educational institutions consider our values and ethical standards in the wake of 2020, libraries need to scrutinize how those values and standards connect with our licensing and purchasing decisions. “Critical Librarianship”, which is based on a foundation of social justice, the belief that everyone deserves equal opportunities and basic economic, political, and social rights, is at the forefront of work being done by librarians across the country. There is an existing body of literature about the contents of the library collections themselves, with respect to issues like decolonization and open access. These collections, used by students, instructors, and researchers ...


British Neocolonialism In Malaya And Singapore, And Us Empire In The Pacific, Wen-Qing NGOEI 2022 Singapore Management University

British Neocolonialism In Malaya And Singapore, And Us Empire In The Pacific, Wen-Qing Ngoei

Research Collection School of Social Sciences

This essay places the Vietnam War upon that larger canvas of Southeast and East Asian history by studying the long shadow that Britain’s Empire cast over U.S. entanglements across the region. Though historians have studied Anglo-American relations in Cold War Southeast Asia, scholarship on the subject remains piecemeal. There are valuable studies of U.S.-British interactions in the early 1960s with respect to the Vietnam conflict or the Indonesia-Malaysia rivalry known as the Confrontation. And there are insightful considerations of U.S. reactions to Britain’s pull-out from Singapore from the end of the 1960s. But only ...

Parent-Child Relations, Sleep, And Externalizing Problems In Clinical Youth, Tiffany Thao Vo 2022 Loma Linda University

Parent-Child Relations, Sleep, And Externalizing Problems In Clinical Youth, Tiffany Thao Vo

Loma Linda University Electronic Theses, Dissertations & Projects

Sleep problems are a major prevailing concern in clinical youth populations. Research has shown that poor sleep is correlated with mental health problems, while parent-child relationships are associated with externalizing behaviors. The aim of this study was to (1) replicate these findings; (2) extend on previous research on the relationships between sleep, parent-child relationships, and externalizing problems; and (3) analyze moderating effects of parent-child relationships on the relationship between sleep and externalizing problems in youth (N = 25) ages 6 to 11 presenting to mental health treatment. Bivariate analyses indicated average objective sleep duration is related to parent-child relations and parent-child ...


Legal And Ethical Issues In Telepsychology: A Handbook For Psychologists, Dexter Chia 2022 Loma Linda University

Legal And Ethical Issues In Telepsychology: A Handbook For Psychologists, Dexter Chia

Loma Linda University Electronic Theses, Dissertations & Projects

This doctoral project sought to examine the various aspects of the modality of telepsychology in a handbook that can be referenced by licensed psychologists. Telepsychology’s growth in the general psychology community has caused greater attention towards its unique legal and ethical considerations when working with clients. We analyze legal and ethical issues inherent to the domains of licensure, clinical practice liability coverage, billing/payment, competence, client welfare, consent, confidentiality, and boundary navigation. After this analysis, we introduce a series of scenarios for readers to apply the discussed considerations to exercise critical thinking.


Effects Of Parents’ Mbsr On Internalizing Problems In Children: Asd As Moderator, Hadley McGregor 2022 Loma Linda University

Effects Of Parents’ Mbsr On Internalizing Problems In Children: Asd As Moderator, Hadley Mcgregor

Loma Linda University Electronic Theses, Dissertations & Projects

Children with autism spectrum disorders (ASD) are at high risk for increased levels of behavior problems and developing internalizing problems. Previous literature has highlighted the impact of parental stress on the development of behavioral problems in children with ASD; however, little research has examined the relation between parenting stress and internalizing problems in children with ASD. The current study utilized data from the Mindful Awareness for Parenting Stress (MAPS) study which consisted of families of 80 preschool children with developmental delays (DD) (N = 31) and children with ASD (N = 49) whose parents reported high levels of stress. Specifically, we investigated ...


Dsm-5 Eating Disorders And Disordered Eating Behaviors In The Lgbt Population, Lacie Parker 2022 Loma Linda University

Dsm-5 Eating Disorders And Disordered Eating Behaviors In The Lgbt Population, Lacie Parker

Loma Linda University Electronic Theses, Dissertations & Projects

According to Meyer’s sexual minority stress model (2003), LGB individuals experience a higher prevalence of psychopathology, which is attributable to the increased stress (i.e., stigma and prejudice) adult sexual minority individuals experience. This model was later adapted by Hendricks and Testa (2012) to include transgender and gender non-conforming individuals. More specifically, this literature review examined the empirical literature regarding the rates and types of, and risk and protective factors for eating disorders and disordered eating behaviors in the general LGBT adolescent and adult populations, in addition to each individual subgroup (i.e., lesbians, gay men, bisexuals, transgender individuals ...


First Responder Coping And Its Impact On Resilience, Ptsd Symptomology, And Hypervigilance, Bianca Bullock 2022 National Louis University

First Responder Coping And Its Impact On Resilience, Ptsd Symptomology, And Hypervigilance, Bianca Bullock

Dissertations

The present study investigated coping strategies utilized by first responders and how those strategies relate to resilience, PTSD symptomology, and hypervigilance. The purpose of this study is to help provide more detailed information as to how first responders’ coping impacts their overall functioning. First responders (N = 181), including law enforcement officers, firefighters, paramedics, and emergency medical technicians, completed online surveys measuring whether engaged or disengaged coping strategies were used to manage stressful situations. Self-perceived resilience, PTSD symptoms, and hypervigilance were also measured. A one-way between-groups multivariate analysis of variance was performed to test the relationships between engaged versus disengaged coping ...


Improved Marginal Likelihood Estimation Via Power Posteriors And Importance Sampling, Yong LI, Nianling WANG, Jun YU 2022 Singapore Management University

Improved Marginal Likelihood Estimation Via Power Posteriors And Importance Sampling, Yong Li, Nianling Wang, Jun Yu

Research Collection School Of Economics

Power posteriors have become popular in estimating the marginal likelihood of a Bayesian model. A power posterior is referred to as the posterior distribution that is proportional to the likelihood raised to a power b∈[0,1]. Important power-posterior-based algorithms include thermodynamic integration (TI) of Friel and Pettitt (2008) and steppingstone sampling (SS) of Xie et al. (2011). In this paper, it is shown that the Bernstein–von Mises (BvM) theorem holds for power posteriors under regularity conditions. Due to the BvM theorem, power posteriors, when adjusted by the square root of the auxiliary constant, have the same limit distribution ...


Ambivalent Sexism And Condom Use Self-Efficacy Amongst Men Who Bottom: A Serial Mediation Model, Elliott Nolan DeVore 2022 University of Tennessee, Knoxville

Ambivalent Sexism And Condom Use Self-Efficacy Amongst Men Who Bottom: A Serial Mediation Model, Elliott Nolan Devore

Doctoral Dissertations

The effects of gendered power dynamics between men and women during sexual encounters are well documented in the literature. Specifically, internalizing sexist beliefs about masculine dominance and feminine submission is related to worse sexual health outcomes. Less is known, however, about gendered power dynamics between men having sex. Those who engage in anal sex as the receptive partner (i.e., bottom) are feminized and shamed in various cultures, viewed as submissive, and may have internalized sexist beliefs and, thus, sexual role prejudice. Consequently, bottoms may feel less sexual autonomy, which influences their condom use self-efficacy. This is important given that ...


Understanding Help-Seeking In Rural Counties: A Serial Mediation Model Of Self-Reliance, Stigma, And Attitudes Toward Psychologists, Emily M. Keller 2022 University of Tennessee, Knoxville

Understanding Help-Seeking In Rural Counties: A Serial Mediation Model Of Self-Reliance, Stigma, And Attitudes Toward Psychologists, Emily M. Keller

Doctoral Dissertations

Rural areas in the Southern United States are characterized by certain cultural values, including self-reliance. Prior research has shown that cultural values can affect stigmatizing beliefs about mental health needs and service utilization. The present study examined a four-stage chain of serial mediation where higher levels of general self-reliance would be related to increased levels of public stigma, which would, in turn, be related to greater levels of self-stigma, followed by higher self-reliance about managing mental health problems, and finally, more negative attitudes toward seeking out help from psychologists. Community members who lived in rural counties in the Southern United ...


Adverse Childhood Experiences And College Adjustment: A Moderated Mediation Model, Pamela Rosecrance 2022 University of Tennessee, Knoxville

Adverse Childhood Experiences And College Adjustment: A Moderated Mediation Model, Pamela Rosecrance

Doctoral Dissertations

Although the effects of adverse childhood experiences have been widely studied in the general population, researchers have just recently begun to examine their effects on college students. Even fewer studies have looked at the impact of adverse childhood experiences on college adjustment. The present study sought to examine mental health concerns as a mediator, first-generation status as a moderator, and the moderated mediation link between adverse childhood experiences and college adjustment. Using this same model, the subconstructs of college adjustment – academic, relational, and psychological functioning – were also investigated. Additionally, we sought to examine differences in the rates of adverse childhood ...


Using Poultry To Enhance Food Security In Stann Creek, Belize, Emily Spatz 2022 University of Arkansas, Fayetteville

Using Poultry To Enhance Food Security In Stann Creek, Belize, Emily Spatz

Poultry Science Undergraduate Honors Theses

Food insecurity is a growing issue in developing and developed countries alike, and in countries like Belize, the prevalence of hunger has soared in recent years. Not having access to diets with sufficient calories and nutrients leads to a host of developmental issues, including stunting and cognitive delays. The purpose of this work was to create an all-encompassing manual for small-scale broiler production, with the intention of another honors student overseeing the implementation of the ideas set forth in the manual, in order to provide nourishment for the students and staff of a school in Belize. After determining that the ...


Lifetime Racism And John Henryism On Cognition And Cardiovascular Health In Black Men, Roy Mitchell 2022 National Louis University

Lifetime Racism And John Henryism On Cognition And Cardiovascular Health In Black Men, Roy Mitchell

Dissertations

Lifetime racism is a type of chronic stress that is often accompanied by depression. Racism is the experience of many Black men because of several psychosocial stressors such as reduced resources and institutional barriers, to name a few. Active coping is typically utilized by Black men as a consistent means to reduce the negative outcomes linked to racism, however, this up-tempo coping style can contribute to poor cardiovascular health and cognitive impairment over time. The present study aimed to provide data to support the effects of lifetime racism and active coping on cardiovascular health and cognition. There were three hypotheses ...


The Association Of Military Sexual Harassment/Assault With Suicidal Ideation, Plans, Attempts, And Mortality Among Service Members And Veterans: A Meta-Analysis And Research Study, Whitney S. Livingston 2022 Utah State University

The Association Of Military Sexual Harassment/Assault With Suicidal Ideation, Plans, Attempts, And Mortality Among Service Members And Veterans: A Meta-Analysis And Research Study, Whitney S. Livingston

All Graduate Theses and Dissertations

Rates of death by suicide and sexual harassment/assault that occurs during military service (MSH/A) are higher among service members/veterans than rates of suicide and sexual violence among civilians. Suicide risk includes thoughts and attempts, and research examining the strength of the relationship between suicide risk and sexual violence across past studies that examined this association are limited to civilians. Moreover, current theories hypothesizing which factors are related to suicide risk do not adequately predict suicide among service members and veterans, and do not account for factors such as MSH/A. This two-study dissertation first calculated the magnitude ...


The Impact Of Racial And Ethnic Socialization On Young Black Women's Roles In Interpersonal And Romantic Relationships: A Quantitative Study, Jessica L. Elliott 2022 Seton Hall University

The Impact Of Racial And Ethnic Socialization On Young Black Women's Roles In Interpersonal And Romantic Relationships: A Quantitative Study, Jessica L. Elliott

Seton Hall University Dissertations and Theses (ETDs)

Children often receive their first understanding of the nuances of society and how to navigate their experiences from parents and family members. Parents and family members of children of color have the additional task of teaching their children how to navigate through society as a person of color. The present study used grounded theory (Charmaz, 2014) and operated from a constructivist–interpretivist and critical–ideological paradigm (Ponterotto, 2005) to specifically explore the racial and ethnic socialization messages young Black women received in childhood and adolescence regarding the expectations of their roles in these relationships and how these messages impacted them ...
