Background: We present results of the development and feasibility testing of CATCH Healthy Smiles, a school-based oral health program, among children in grades K-2 in Houston, Texas. Methods: Study design was cross-sectional (N = 2 schools; N = 125 parent-child dyads; 31 kindergarteners, 42 first graders, and 52 second graders). CATCH Healthy…

This study explored the transition from secondary to postsecondary education among a national sample of students who had or had not studied music in high school. Using evidence from the High School Longitudinal Study of 2009, a nationally representative longitudinal study of 21,440 American high school students who were ninth graders in the…

The ability of universities and colleges to predict the success of admitted students continues to be a key concern of higher education officials. Apart from a desire to see students have successful academic careers, there is also the fiscal reality of greater tuition revenues providing needed support for university budgets. Using administrative…

Often in sociology, researchers are confronted with nonnormal variables whose joint distribution they wish to explore. Yet, assumptions of common measures of dependence can fail or estimating such dependence is computationally intensive. This article presents the copula method for modeling the joint distribution of two random variables, including…

The present simulation study indicates that a method where the regression effect of a predictor (X) on an outcome at follow-up (Y1) is calculated while adjusting for the outcome at baseline (Y0) can give spurious findings, especially when there is a strong correlation between X and Y0 and when the test-retest correlation between Y0 and Y1 is…

The commenter's proposal may be a reasonable method for addressing uncertainty in predictive modeling, where the goal is to predict "y." In a treatment effects framework, where the goal is causal inference by conditioning-on-observables, the commenter's proposal is deeply flawed. The proposal (1) ignores the definition of…

The current study represents the first longitudinal investigation of the potential effects of breastfeeding duration on maternal sensitivity over the following decade. This study also examined whether infant attachment security at 24 months would mediate longitudinal relations between breastfeeding duration and changes in maternal sensitivity over…

Because business statistics students often experience a lack of statistical motivation, business educators need to understand the factors that influence students' motivation levels in undergraduate-level business statistics courses. The purpose of this study was to examine the role of math self-efficacy and self-compassion on students' motivation…

The current study aimed to understand not only students' attitudes towards statistics, but also their beliefs about their ability to perform statistical tasks (self-efficacy), the value they place on carrying out course and statistical tasks (task value), and the level of effort they perceive when engaging in these tasks (cost) across a semester…

We consider two-level models where a continuous response R and continuous covariates C are assumed missing at random. Inferences based on maximum likelihood or Bayes are routinely made by estimating their joint normal distribution from observed data R[subscript obs] and C[subscript obs]. However, if the model for R given C includes random…

This research aims to explore the relations between social justice leadership, sense of school belonging, and student resilience. The research was conducted with 549 high school students. The data was collected through the social justice leadership scale, the psychological sense of school membership scale, and student resilience scale. The…

Organized sports are among the most common youth activities in the United States, and athletic coaches can often become important mentors to their players. Nonetheless, few studies have examined the characteristics of youth who form mentoring relationships with coaches and whether such relationships are associated with later academic outcomes.…

The challenge of a long and difficult commute to school each day is likely to wear on students, leading some to change schools. We used administrative data from approximately 3,900 students in the Baltimore City Public School System in 2014-2015 to estimate the relationship between travel time on public transportation and school transfer during…

This study posits a bioecological positivity to success (BEPS) model and examines how diverse bioecological factors predict graduates' career success. The BEPS model with an emphasis on hard (e.g. science, technology, engineering and mathematics [STEM]) and soft (e.g. interpersonal and critical thinking) skills generate a hypothetical model:…

The literature on educational choices and participation has tended to focus on youth and to some extent on older adults, with little attention to the group in between. This paper therefore analyses participation in various types of learning by people in their 30s and 40s. This group are often juggling career and family life commitments meaning…
