In this work, we delve into geometric analysis, particularly examining the interplay between lower bounds on Ricci curvature and specific functionals. Our exploration begins with an investigation into the implications of Yamabe invariants for asymptotically Poincare-Einstein manifolds and their conformal boundaries under conditions of…

In Single-Case Designs (SCD), the outcome variable most commonly involves some form of count data. However, statistical analyses and associated effect size (ES) calculations for count outcomes have only recently been proposed. Three recently proposed ES methods for count data are: Nonlinear Bayesian effect size (Rindskopf, 2014), Log Response…

In many psychological and educational applications, it is imperative to obtain valid and reliable score estimates of multilevel processes. For example, in order to assess the quality and characteristics of high impact learning processes, one must compute accurate scores representative of student- and classroom-level constructs. Currently, there…

With adolescent mental health concerns on the rise, it is important that school counselors provide adequate support in the areas of academic, career, and social/emotional support. Yet, there are few scales that look at the perceptions of students around the support that their school counselors provide in these areas. This study sought to validate…

This quantitative survey study investigated factors that influence off-campus student housing selection and residential satisfaction. Data from 733 full-time students living in the University City area of Philadelphia was used for analysis. Multiple imputation and reliability tests were conducted to ensure validity and reliability of the study.…

Within the field of music education, previous literature has examined numerous features of relationships between students and teachers, but survey instruments measuring these relationships from the student perspective are lacking. Accordingly, two studies were conducted to develop and evaluate a new survey instrument measuring students'…

Clinical reasoning is widely used among several medical professionals and personnel to diagnose conditions to streamline the treatment process in an effective manner. Researchers have explored clinical reasoning in nursing literature and the medical profession, however, have not been explored in counselor education despite counselors being one of…

Previous research has individually assessed parallel analysis and minimum average partial for factor retention in exploratory factor analysis using ordinal variables. The current study is a comprehensive simulation study including the manipulation of eight conditions (type of correlation matrix, sample size, number of variables per factor, number…

The purpose of this study was to examine the psychometric properties of the Precalculus Concept Assessment (PCA), a 25-item multiple-choice instrument designed to assess student reasoning abilities and understanding of foundational calculus concepts (Carlson et al., 2010). When this study was conducted, the extant research on the PCA and the PCA…

The purpose of this study was to determine any relationship between three factors of the TPACK model and the impact of age and gender of foreign language teachers who teach in post-secondary education. The goal was to help instructional designers to develop need-based training for in-service language teaching faculty in higher education.…

This dissertation analyzes the production and perception of lexical stress in trilinguals' first, second, and third languages (L1, L2, and L3) to evaluate how the cue-weighting transfer hypothesis applies to L3 acquisition. According to this hypothesis, acoustic cues to stress have different weights across languages, and results from both…

Enabling learners to successfully use their second language (L2) in meaningful ways is a critical goal of instruction. Ultimately, most learners want to meet the L2 demands of the contexts in which they will use the language. To accomplish this, learners must develop linguistic knowledge and apply it in a manner that is contextually appropriate…

The privacy paradox is a phenomenon whereby individuals continue to disclose their personal information, contrary to their claim of concerns for the privacy of their personal information. This study investigated the privacy paradox to better understand individuals' decisions to disclose or withhold their personal information. The study argued that…

Social cognitive theory was developed to explain how individuals learn, in part, by witnessing the behavior of others. Self-efficacy is a construct within social cognitive theory which indicates the beliefs that an individual can be successful at a task under specific situational demands. The sources of self-efficacy include self-evaluating past…

The purpose of this study was to examine the construct validity of social loafing using convergent and discriminant validity principles. Three instruments that purport to measure social loafing were factor analyzed: A ten-item instrument by George (1992), a 13-item instrument by Mulvey and Klein (1998), and a 22-item instrument by Jassawalla,…
