The present article aims to show how to model longitudinal change in cohort sequential data applying latent true change models using Mplus' multi-group approach. The underlying modeling ideas are described and explained in this article. As an example, change in internalizing problem behaviors between the age of 8 and 13 years is modeled and…

This study aimed to identify factors motivating individuals to earn a doctoral degree in library and information science. Data about doctoral student motivation was collected from first-year students through a survey, semi-structured interviews, and personal admission statements. Findings suggest five motivating factors: research-related…

Background: Although use of Electronic Nicotine Delivery Systems (ENDS) is increasingly prevalent among young adults, little is known about predictors of ENDS initiation among this population. Aims: We examined the roles of the social environment (i.e., peer ENDS use and household ENDS use), normative beliefs (i.e., social acceptability of ENDS…

We hypothesized that in adolescence, maladaptive narcissism interacts with low self-esteem to predict a preoccupied attachment style ("attachment for self-affirmation hypothesis"), and with high self-esteem to predict an avoidant attachment style ("attachment for self-enhancement hypothesis"). We expected gender differences in…

In recent years there has been considerable interest in how many learners complete MOOCs, and what factors during usage can predict completion. Others, however, have argued that many learners never intend to complete MOOCs, and take MOOCs for other reasons. There has been qualitative research into why learners take MOOCs, but the link between…

Each year employees aggressively seek undergraduate business students to fill openings in their companies. While the number of universities offering sales programs is growing, it is apparent students' desire to pursue a career in sales continues to lag behind demand for sales professionals. This article presents a study of college-bound high…

Doctoral education programs, being the cradle of the next-generation scientists and scholars, undertake the mission of transforming a talented student into a promising scholar. This transformation is featured by two simultaneous processes: academic professionalization and scholarly socialization. Institutional environment, academic advisors, and…

In the United States, federal mandates require local education agencies to provide education to students with disabilities in the least restrictive environment. As a result, students with disabilities are included in the general education classroom for varying amounts of the school day depending on their educational goals and individual needs. For…

This research was designed in the screening model to determine the opinions of high school students on tourism effects and geography-tourism relations. The data were gathered from 760 students who were educated in high schools in the central district of Kütahya, identified by cluster sampling method. The data were collected with the help of a…

The next generation of professors will come from today's graduate students and post-doctoral fellows, but we do not know much about their preparation to use research-validated teaching practices. This study characterizes the teaching beliefs of graduate students and post-doctoral fellows who represent future geoscience instructors though we…

The current study utilizes the theory of planned behavior (Ajzen "Organizational Behavior and Human Decision Processes," 50, 179-211 Ajzen 1991) to examine an instructor confirmation-interaction model in the instructional communication context to discover a means by which instructors might cultivate positive student attitudes and…

During their time as Teaching Assistants (TAs), graduate students develop a variety of skills, knowledge, and attitudes (SKAs) based on teaching and related facilitation experiences. As TAs move on to future opportunities, their prior experiences form a foundation upon which additional teaching experience builds. Presently, there are few tools to…

Background: Sexual minority young people have demonstrated higher rates of emotional distress and suicidality in comparison to heterosexual peers. Research to date has not examined trends in these disparities, specifically, whether there have been disparity reductions or increases and how outcomes have differed over time by sex and sexual…

This study used a structural equation model to investigate the endogenous structure of high school students' perceptions of the knowledge possessed by English teachers who handle technology-supported classes in Taiwan. We developed a validated survey composed of four constructs, namely, subject matter knowledge (SMK, 5 items), knowledge of…
