Statistical Power In Meta-Analysis, Jin Liu Dec 2015

Statistical Power In Meta-Analysis, Jin Liu

Theses and Dissertations

Statistical power is important in a meta-analysis study, although few studies have examined the performance of simulated power in meta-analysis. The purpose of this study is to inform researchers about statistical power estimation on two sample mean difference test under different situations: (1) the discrepancy between the analytical power and the actual power and (2) the influence of unequal sample size and unbalanced design on the power. Results indicated that there are noticeable discrepancies between the estimated power and actual power under certain conditions. In general, unbalanced design decreases the statistical power in the meta-analysis. Recommendations are provided for researchers …


Empirical Connections Between The Construct Of Value, The Quality Of Stability, And The Construct Of Regret, William Samuel Morris Jr. Dec 2015

Empirical Connections Between The Construct Of Value, The Quality Of Stability, And The Construct Of Regret, William Samuel Morris Jr.

Theses and Dissertations

The term value is a psychological construct frequently used in the social sciences. This research addresses the issue of stability of ratings of perceived value of participants for monetary, tangible, and intangible items that cross contexts. Also elucidated is the relationship of value to regret. Hypothesis one stated that value would be stable across time and different rating conditions. Forty-four participants rated the value of 72 stimulus items at two time points and in different contexts. Paired samples t-tests indicated 28 participants had no statistical difference in scores. Twenty-eight scores out of 44, when applied to a binomial test, indicates …


A Comparison Of Three Levels Of Verbal Redundancy In Multimedia Learning And Its Effects On Memory Retention And Transfer In Legal Professionals, Angela Mizell Dooley Dec 2015

A Comparison Of Three Levels Of Verbal Redundancy In Multimedia Learning And Its Effects On Memory Retention And Transfer In Legal Professionals, Angela Mizell Dooley

Theses and Dissertations

This study sought to examine verbal redundancy in multimedia learning and its effects on memory retention and transfer in legal professionals who were randomly assigned to watch one of three multimedia videos. Tests of ANOVA showed no significant differences in performance, mental load, or combined efficiency scores among the three instructional groups, but participants in the complementary text group rated the video with complementary slides as significantly more helpful than the videos with redundant, overloaded text slides and spoken words only. Factorial ANOVA also revealed that the redundant text group with fewer than five years of experience scored significantly lower …


Middle School Students' Perceptions Of Fairness And Trust In Assessment Scenarios, Corinne Elaine Jimenez Jan 2015

Middle School Students' Perceptions Of Fairness And Trust In Assessment Scenarios, Corinne Elaine Jimenez

Theses and Dissertations

Fairness in assessment practices is an elusive concept which has been explored in some detail at the university level, but rarely with students in middle school. This study examines students’ perceptions of fairness on nine classroom assessment practices. It also studies if students’ perceptions of fairness, as well as student gender, could predict their levels of trust. Students were able to discern fair practices, as defined by alignment to best assessment practice literature, from unfair practices for most scenarios. They were more inclined to recognize interactional fairness deviations or promotions. The student’s ability to identify a fair or unfair situation …


Decision-Making Processes Of Judges In Family Court: An Investigation Of Salient Features Relating To Termination Of Parental Rights Hearings, Jennifer G. May Jan 2015

Decision-Making Processes Of Judges In Family Court: An Investigation Of Salient Features Relating To Termination Of Parental Rights Hearings, Jennifer G. May

Theses and Dissertations

This qualitative study uses Corbin and Strauss’ approach to the Grounded Theory method of analysis to determine the salient features of decision-making in termination of parental rights (TPR) hearings. Specifically this study addresses: what information is used to make decisions in a TPR case; what training or systemic improvements are needed; the role of intuition, prior experience or other stores of knowledge; how judges prioritize sources of information; and how “best interest of the child” is interpreted by family court judges. A theory of judicial decision-making relating specifically to TPR hearings is proposed.


An Evaluation Of A Mediational Model Of Adolescent Global Life Satisfaction, Michael D. Lyons Aug 2014

An Evaluation Of A Mediational Model Of Adolescent Global Life Satisfaction, Michael D. Lyons

Theses and Dissertations

This study extended previous research by simultaneously examining determinants and presumed psychosocial mechanisms related to the development of individual differences in adolescent life satisfaction, based on Evans‟ (1994) proposed model. Specifically, this study assessed the relations between personality (extraversion, neuroticism) and environmental experiences (stressful life events) on early adolescents‟ global life satisfaction as mediated by approach and avoidance coping behaviors using a sample of 529 students from one middle school in the south eastern United States. The results of this study found partial evidence to support Evans‟ model. Statistically significant relations were found for a number of individual pathways between …


Surgency Characteristics Relating To Attention Deficit/Hyperactivity Disorder And Autism Spectrum Disorders In Boys With Fxs, Marjorie Lee Grefer Jan 2013

Surgency Characteristics Relating To Attention Deficit/Hyperactivity Disorder And Autism Spectrum Disorders In Boys With Fxs, Marjorie Lee Grefer

Theses and Dissertations

Children with fragile X syndrome (FXS) are at high risk for developing a range of behavioral disorders, including Attention Deficit/Hyperactivity Disorder (ADHD) and autism spectrum disorders (ASD). However, very few studies have investigated the comorbid profile of FXS and ADHD and the possible dissociation from the FXS and ASD profile. The present study examined the relationship of childhood temperament characteristics of the Surgency facet (activity level, impulsivity, approach, shyness, and smiling and laughter) and the severity of ADHD and ASD features at two measurement time points in childhood, preschool (ages 3-4) and at school entry (ages 5-6). The study consisted …


Cortisol And Working Memory In Boys With Fragile X Syndrome, Jessica F. Scherr Jan 2013

Cortisol And Working Memory In Boys With Fragile X Syndrome, Jessica F. Scherr

Theses and Dissertations

Fragile X Syndrome (FXS) is a neurodevelopmental disorder and the most common cause of inherited intellectual disability. Although FXS is associated with global cognitive impairments, specific deficits in working memory have been reported in young males with FXS. Working memory is an important cognitive process that involves the ability to temporarily store and manipulate information over a short period of time. Deficits in working memory can negatively impact an individual's academic, behavioral, and social functioning. Chronic stress can adversely influence working memory performance and can be measured physiologically through salivary cortisol. It is important to study the complex relationship of …


The Relationship Of South Carolina Teachers' Work-Related Stress With Years Of Experience, Feelings And Coping Strategy, Michelle Munnell Jan 2013

The Relationship Of South Carolina Teachers' Work-Related Stress With Years Of Experience, Feelings And Coping Strategy, Michelle Munnell

Theses and Dissertations

Background. Stress has been found to affect workers in various occupations, and teaching appears particularly stressful. Work-Related Stress (WRS) affects teachers and people with whom they interact. Previous research suggests WRS may be related to characteristics including teaching experience, feelings, and coping strategy. Objective. The purpose of this study was to investigate further the relationship of teacher stress, while expanding the investigation in several areas: utilizing a different geographic population, broadening the focus to generic WRS, and including teachers with less experience. Current model builds on Kyriacou and Sutcliffe's (1978) and Tolbert's (2007) teacher stress models. This study examined relationships …


Variability Across Repeat Assessment Of Working Memory And Processing Speed In Referred Populations, Dawn Baker Jan 2013

Variability Across Repeat Assessment Of Working Memory And Processing Speed In Referred Populations, Dawn Baker

Theses and Dissertations

Developmentally, it is expected that the processes of working memory and processing speed will improve throughout childhood as a child's brain develops. However, students with learning, attention, and other childhood disorders often display difficulties in these areas. This study investigated the use of repeated measures to ascertain variability over time of two important cognitive processes: Working Memory and Processing Speed in a clinically referred population as measured by the WISC-IV to determine if a significant discrepancy exists between administrations. The study also investigated whether differences in Working Memory and Processing Speed from administration to administration would be greater in children …
