Risk Factors For Social Isolation In Older Korean Americans, Yuri Jang, Nan Sook Park, David A. Chiriboga, Hyungwoo Yoon, Jisook Ko, Juyoung Lee, Miyong T. Kim

Social Work Faculty Publications

Objective: Given the importance of social ties and connectedness in the lives of older ethnic immigrants, the present study examined the prevalence of social isolation and its risk factors in older Korean Americans.

Method: Using survey data from 1,301 participants (M_age = 70.5, SD = 7.24), risk groups for marginal social ties with family and friends were identified and predictors of each type of social isolation explored.

Results: Male gender and poorer rating of health were identified as common risk factors for marginal ties to both family and friends. Findings also present specific risk factors for each type …

The Spinning Apparatus Of Webspinners – Functional-Morphology, Morphometrics And Spinning Behaviour, Sebastian Büsse, Thomas Hörnschemeyer, Kyle Hohu, David Mcmillan, Janice Edgerly-Rooks

Biology

Webspinners (Insecta: Embioptera) have a distinctly unique behaviour with related morphological characteristics. Producing silk with the basitarsomeres of their forelegs plays a crucial role in the lives of these insects – providing shelter and protection. The correlation between body size, morphology and morphometrics of the spinning apparatus and the spinning behaviour of Embioptera was investigated for seven species using state-of-the-art methodology for behavioural as well as for morphological approaches. Independent contrast analysis revealed correlations between morphometric characters and body size. Larger webspinners in this study have glands with greater reservoir volume, but in proportionally smaller tarsi relative to body size …

The Effects Of Social Status On The Quality And Affordability Of Healthcare, Robert O. Burns

Honors College Theses

Access to healthcare is very important in today's society, as is the quality of said healthcare. The socioeconomic status (SES) of an individual is the most important factor when it comes to determining both the accessibility and quality of said care, and as such has been studied extensively. Across different countries, lower SES has been linked to the decreased affordability and success rates of medical treatments such as coronary heart disease medication or health risk prevention regimes. In many cases, low SES patients were found to be less likely to seek treatment than higher SES patients as the debt they …

Tackling Nigeria's Security Challenges: Negotiation Or What With Boko Haram?, Phillip E. Agbebaku, William E. Odion, Mary Fadal Edokpa

Journal of Global Initiatives: Policy, Pedagogy, Perspective

For many years now Nigeria has been facing a plethora of security challenges. This includes the Niger Delta militants who engaged in disrupting oil exploration by kidnapping oil workers in the Niger Delta region of Nigeria. Their grievance was that the region that produces the wealth of the nation was neglected in terms of development. They wanted a better deal. The conflict situation improved with the declaration of Amnesty by the Yar’Adua administration. Another security challenge was posed by the Boko Haram insurgency. Boko Haram reared its ugly head in full force in 2011. The insurgency concentrated in the North …

Professional Sports Facilities, Teams And Property Values: Evidence From Seattle’S Key Arena, Brad R. Humphreys, Adam D. Nowak

Economics Faculty Working Papers Series

Professional sports teams and facilities can generate negative or positive amenities to be capitalized into nearby property prices. We investigate the effect of the departure of a National Basketball Association team, the Seattle SuperSonics, from Key Arena in Seattle in 2008 on nearby residential property values. The arena continued to operate after the team left, so this departure represents a natural experiment to identify the net effects of a sports team from the effect of a facility and other events that take place in the facility. Results from a repeat sale regression model indicate that the departure of the SuperSonics …

Enhancing Psychology Majors’ Meta-Cognitive Understanding Of Desirable Workplace Skills Using A Short Discussion-Based In-Class Activity, Alena S. Gordienko

Masters Theses, 2010-2019

The skills psychology students possess that employers look for in job applicants include: reliability, integrity, work ethic, communication, technology, critical thinking, teamwork, and professionalism (Rodgers, 2012). I conducted a study to determine whether participating in a brief classroom activity would improve students’ ability to effectively describe their skills. Students were asked to write a cover letter before and after the activity. The activity included a discussion of four skills and student reflection on their experiences that demonstrated these skills. I hypothesized that overall letter-writing would improve, that students’ self-reported levels of preparedness to find a job would improve, that students …

Establishing Conditioned Reinforcers In Children With Autism Spectrum Disorder, Kristen Rollman

Masters Theses, 2010-2019

People with Autism Spectrum Disorder (ASD) often demonstrate restricted, repetitive patterns of behaviors, interests, and activities, often involving preoccupations with one or more stereotyped and restricted patterns of interest and an inability to adjust to changes in daily routines and schedules. Academic achievement and skill acquisition present a challenge in children with ASD, often times due to a lack of reinforcer options resulting from these deficits. The current study examines the use of free-operant stimulus preference assessments, progressive-ratio schedule reinforcer analyses, and a Pavlovian conditioning procedure in order to evaluate the establishment of new reinforcers that may be used to …

Delay Discounting: Are Magnitude Effects Moderated By Domain Effects?, David A. Williams Jr.

Masters Theses, 2010-2019

Delay discounting is a phenomenon wherein a commodity loses its value as the delay to its receipt increases. It may be conceptualized as a measure of patience, or impatience. There are several aspects of a commodity that contribute to its loss in value, in addition to the delay to its receipt. Specifically, there are differential rates in delay discounting across commodity types (domain effects) and commodity amounts (magnitude effects). Interestingly, magnitude effects occur almost exclusively in relation to a particular commodity type: monetary rewards. The present study sought to isolate magnitude effects from a particular quality of monetary rewards: fungibility. …

The Effects Of Ordinal Data On Coefficient Alpha, Kathryn E. Pinder

Masters Theses, 2010-2019

Given coefficient alpha’s wide prevalence as a measure of internal reliability, it is important to know the conditions under which it is an appropriate estimate of reliability. The present paper explores alpha’s assumption of uncorrelated errors when used with ordinal data. Alpha overestimates true reliability when correlated errors are present. In this paper, I use a simulation study to recreate three mechanisms proposed to create correlated errors in ordinal data. The first mechanism, misclassification error, occurs when there are correlated measurement errors present in the data. The second mechanism, grouping error, occurs when there are not enough categories to represent …

Traumatic Experiences And Cognition: How Do Static And Dynamic Variables Contribute To Current Functioning?, Cathryn Richmond

Masters Theses, 2010-2019

Approximately 25% of children in the United States will witness or experience a traumatic event before age 4, and individuals with a history of trauma, particularly traumatic events in childhood, have a much higher likelihood of developing psychopathology in adulthood. Prior research indicates that the vast majority of individuals with a serious mental illness, particularly those in community mental health centers and psychiatric inpatient settings, have experienced at least one traumatic event in their lifetime. These individuals require special consideration in treatment planning, and a large range of neurodevelopmental and environmental factors must be taken into account when interpreting results …

Predicting Bystander Attitudes Using Rape Myth Acceptance And Adherence To The Commodity Model Of Sex, Kimberly J. Johnson

Masters Theses, 2010-2019

The high rate of sexual assault on college campuses has become a growing concern among college administrators. To combat the prevalence of sexual assault, colleges and universities have begun implementing mandatory bystander intervention training programs, which teach students to look for warning signs indicative of sexual assault and intervene before an assault occurs. Previous research has indicated that an individual’s endorsement of rape myths may play a role in whether or not that individual will intervene in a situation that may lead to sexual assault; however, little research has investigated from where beliefs in rape myths might stem. Sex educators …

The Use Of Differential Reinforcement To Increase Participation/Engagement In Children With Autism In An Inclusion Setting, Kayla Gionti

Masters Theses, 2010-2019

Abstract

Children with autism spectrum disorder (ASD) would gain more from instructional material if they increased their participation and engagement in general education classrooms. However, these children often grow dependent on prompts from teachers and paraprofessionals to participate. This can impede the children from participating independently in other settings and from engaging with the instructional material presented to them. The purpose of this study was to increase independent participation, while decreasing the prompt dependency of 3 children with ASD in a general education classroom. The use of differential reinforcement and prompt fading increased the hand raising behavior of all three …

Propensity Score Matching In Higher Education Assessment, Heather D. Harris

Masters Theses, 2010-2019

The applied nature of higher education assessment does not lend itself to rigorous experimental research designs. However, assessment practitioners would like to make claims about the influence of educational programs on student learning outcomes. Propensity score matching (PSM) methods are quasi-experimental techniques that allow researchers to control for known confounding variables. In the context of higher education, PSM techniques allow assessment practitioners to control for confounding variables related to students’ self-selected participation in university programs. Research and recommendations on how to apply PSM techniques are scattered throughout several disciplines. However, additional research is needed to evaluate how well PSM techniques …

Myside Bias In Probabilistic Ethical Decision Making, Richard E. Hohn

Masters Theses, 2010-2019

This study examined the extent to which myside bias was observed in the context of ethical decision making. In judgment and decision making research the resistance of myside bias is described as a component of rational thinking. Thus, to some effect, this study aimed to examine the extent to which people act rationally when making ethical decisions. Measures of thinking dispositions (actively open-minded thinking and need for cognition) as well as measures of cognitive reflection and probabilistic knowledge were included in the study to examine their associations with myside bias in ethical decisions. Modest myside bias effects were observed between …

Persons Can Speak Louder Than Variables: Person-Centered Analyses And The Prediction Of Student Success, Elisabeth M. Pyburn

Masters Theses, 2010-2019

In order to ensure that analyses are appropriate for one’s research question(s), it is important to consider whether a person-centered or variable-centered approach is needed. Person-centered approaches are often not considered in situations for which they would be appropriate. To that end, a description of the characteristics and procedures of two common person-centered analyses (cluster analysis and mixture modeling) are provided. Although both analyses accomplish the same general aim – to group persons based on their similarity on a series of variables, thus providing ease of interpretation – the methods employed for each analysis differ considerably. As illustration, both analyses …

International Distance Coaching Of Therapists To Improve Verbal Behavior By Children With Autism, Ana Barkaia

Masters Theses, 2010-2019

This study examined the effects of distance coaching on the mastery of therapists’ skills and the development of verbal behavior of children with autism. Three therapists and three children receiving early intervention services in the NGO Children of Georgia in the developing country of Georgia-Sakartvelo in Eastern Europe participated in this research. The therapists received distance coaching about the implementation of ABA therapy from Virginia. The intervention was recorded and coded by observers in Georgia-Sakartvelo and in Harrisonburg/Virginia,USA. The effects of distance coaching was investigated within a multiple baseline across participant.

Academic Advising: Helping Promote The Success Of College Students With College Students With Psychiatric Disabilities, Jamie P. Claytor

Educational Specialist, 2009-2019

Academic advisors in higher education include professional full-time staff advisors, faculty advisors, graduate assistants, interns, and staff who serve dual roles as academic advisors and career advisors. Who among these many groups does the advising can have an impact on how advising is delivered and of what the advising process consists. For those students dealing with psychiatric disabilities, they may find themselves suffering academically and afraid to ask for help. It is essential to have an academic advisor who can recognize students in distress, guidelines regarding how to deal with these students, and steps to take when referral to a …

After-School Programming As Intervention For Students With Disabilities, Edward D. Tynan

Educational Specialist, 2009-2019

After-school programs are increasing in popularity, with an estimated 6.5 million students attending organized after-school programs (Harvard Family Research Project, 2008). With the continuing rise in popularity of these programs, more students (including students with disabilities) have access to after-school programs. The purpose of the current research was to discover what current practitioners of school psychology recommend in regards to after-school programming for students with disabilities. All participants were school psychologists or staff members at after-school programs located within either the Richmond, VA region (including the City of Richmond, Chesterfield County, and Henrico County) or the Harrisonburg,VA region (including the …

A Meta-Analytic Tutorial And A Narrative Review On Motivation Interventions In Education, Rory A. Lazowski

Dissertations, 2014-2019

Abstract (Paper 1)

Dating back to only the early 1970’s, the use of meta-analysis has recently grown steadily in the fields of psychology and education, after initially being used in the physical sciences. Meta-analysis is often lauded as an effective analytic tool to inform practice and policy, disentangle conflicting results among single studies, and identify areas that require additional information for a certain topic. However, because routine use of meta-analysis is relatively recent, there remain methodological issues that require clarity. In addition, as more advanced analytical and statistical techniques emerge, there is a need to examine how these techniques can …

Impacts Of Mindfulness On Disruptive Behaviors Associated With Characteristics Of Adhd, Joseph L. Sims

Educational Specialist, 2009-2019

The prevalence of ADHD has drastically increased over the last decade, and children with this disorder often receive attention from their teachers for their disruptive behaviors (Visser, Danielson, Bitsko, Holbrook, Kogan, Ghandour,... & Blumberg, 2014). Students with ADHD often struggle with controlling their impulses that lead to these disruptions in the classroom. If not addressed, the classroom learning environment is likely to be negatively impacted (Lambert, Cartledge, Heward, & Lo, 2006). Introducing students with ADHD to the practice of mindfulness may help to create a space, or a delay in responding, between thoughts and actions which may, in turn, reduce …

How Does Perfectionism Influence Anxiety In Gifted Middle School Students?, Kelsey Owens

Educational Specialist, 2009-2019

Research has demonstrated that gifted students tend to experience a higher level of perfectionism when compared to their regular education peers. While perfectionism may aid these students in their academics, it can also contribute to negative consequences in terms of the social and emotional needs of these students, such as anxiety. This research study sought to add to the literature by examining whether perfectionism does influence anxiety in gifted middle school students. Twenty-two middle school students enrolled in a center-based gifted program participated in this study by completing two measures: one examining levels of perfectionism and another examining levels of …

Teacher Child Interaction Training As A Universal Prevention Program In Preschool And Kindergarten Classrooms, Jessica Rossi

Dissertations, 2014-2019

The current study assessed the effectiveness of Teacher Child Interaction Training (TCIT), an adaptation of Eyberg’s Parent Child Interaction Therapy (PCIT), on teacher and child behaviors in preschool and kindergarten classrooms. The sample included four classrooms in urban, socioeconomically disadvantaged and culturally diverse settings. Two preschool classrooms were included in the first study and one preschool and one kindergarten classroom were included in the second study. Both studies used a concurrent multiple baseline design to evaluate the effects of training and coaching on teacher and child behaviors in the classroom. The intervention focused on the development of a friendly attachment …

Satisfaction Of Students With Visual Impairment Within Different School Settings, Jeremiah Jordan

Educational Specialist, 2009-2019

This is an investigation of the satisfaction of students with visual impairment attending school in different educational settings, including students attending school in a specialized educational setting, as well as students with visual impairment attending school in a mainstreamed educational setting. This paper explores research on the effectiveness and perceptions of inclusion for children with disabilities, particularly children with visual impairment. Specific research on this topic is sparse and the researcher proposed a new research study, in which the satisfaction of students with visual impairment was targeted and explored in both a specialized educational setting and mainstreamed educational setting. High …

The Effects Of A Planned Missingness Design On Examinee Motivation And Psychometric Quality, Matthew S. Swain

Dissertations, 2014-2019

Assessment practitioners in higher education face increasing demands to collect assessment and accountability data to make important inferences about student learning and institutional quality. The validity of these high-stakes decisions is jeopardized, particularly in low-stakes testing contexts, when examinees do not expend sufficient motivation to perform well on the test. This study introduced planned missingness as a potential solution. In planned missingness designs, data on all items are collected but each examinee only completes a subset of items, thus increasing data collection efficiency, reducing examinee burden, and potentially increasing data quality. The current scientific reasoning test served as the Long …

Extending An Irt Mixture Model To Detect Random Responders On Non-Cognitive Polytomously Scored Assessments, Mandalyn R. Swanson

Dissertations, 2014-2019

This study represents an attempt to distinguish two classes of examinees – random responders and valid responders – on non-cognitive assessments in low-stakes testing. The majority of existing literature regarding the detection of random responders in low-stakes settings exists in regard to cognitive tests that are dichotomously scored. However, evidence suggests that random responding occurs on non-cognitive assessments, and as with cognitive measures, the data derived from such measures are used to inform practice. Thus, a threat to test score validity exists if examinees’ response selections do not accurately reflect their underlying level on the construct being assessed. As with …

Examining The Performance Of The Metropolis-Hastings Robbins-Monro Algorithm In The Estimation Of Multilevel Multidimensional Irt Models, Bozhidar M. Bashkov

Dissertations, 2014-2019

The purpose of this study was to review the challenges that exist in the estimation of complex (multidimensional) models applied to complex (multilevel) data and to examine the performance of the recently developed Metropolis-Hastings Robbins-Monro (MH-RM) algorithm (Cai, 2010a, 2010b), designed to overcome these challenges and implemented in both commercial and open-source software programs. Unlike other methods, which either rely on high-dimensional numerical integration or approximation of the entire multidimensional response surface, MH-RM makes use of Fisher’s Identity to employ stochastic imputation (i.e., data augmentation) via the Metropolis-Hastings sampler and then apply the stochastic approximation method of Robbins and Monro …

Addressing Serial-Order And Negative-Keying Effects: A Mixed-Methods Study, Jerusha J. Gerstner

Dissertations, 2014-2019

Researchers have studied item serial-order effects on attitudinal instruments by considering how item-total correlations differ based on the item’s placement within a scale (e.g., Hamilton & Shuminsky, 1990). In addition, other researchers have focused on item negative-keying effects on attitudinal instruments (e.g., Marsh, 1996). Researchers consistently have found that negatively-keyed items relate to one another above and beyond their relationship to the construct intended to be measured. However, only one study (i.e., Bandalos & Coleman, 2012) investigated the combined effects of serial-order and negative-keying on attitudinal instruments. Their brief study found some improvements in fit when attitudinal items were presented …

The Development Of Character Adaptation System (Cast) Intervention, Lauren Mays

Dissertations, 2014-2019

The primary objective of this dissertation was to explore the feasibility and utility of an individualized intervention derived from a group therapy manual grounded in Henriques’ (2011) Unified Theory of Psychology. This framework serves to translate terminology from different theoretical perspectives and map their overlap and distinctive qualities onto human functioning. This project provides a more directive educational approach to explore whether and how clients can be directed to understand these systems and benefit from them. The second goal was to explore the appropriateness and impact of this manual on a client presentation typically seen in college outpatient treatment. These …

A Detailed Analysis Of Coaching In Teacher-Child Interaction Training (Tcit), Krystal M. Studivant

Dissertations, 2014-2019

Teacher-Child Interaction Training (TCIT) is a school-based prevention program in which teachers are taught to use basic principles of behavior modification in the classroom to prevent and reduce problem behaviors in young children. A key aspect of the effectiveness of TCIT is the in-vivo coaching, which allows for immediate feedback during the natural flow of teaching activities with children. The purpose of the current study is two-fold: a) to support the research on the effectiveness of the DePaul TCIT method in preschool classrooms and b) to analyze the content and quality of coaching statements. The intervention was introduced sequentially within …

Teachers’ Beliefs And Practices Related To Student Self-Regulation In The Classroom, Marlana L. Webster

Dissertations, 2014-2019

Self-regulation serves as a pivotal skill for children to acquire early in life. Mastery of the skill leads to high academic achievement and increased sense of self-efficacy. Teachers play a major role in developing self-regulation in children. Consequently, the beliefs and practices that teachers hold regarding poor self-regulation (i.e. inattention and impulsivity) are to be understood and taken into account. The Self-Regulation Survey was created to capture teachers’ attributions for inattention and impulsivity along with subsequent chosen interventions in 52 participants. The results indicated that teachers attribute impulsivity to organic factors and family origin to a greater degree than classroom …
