JMP® Pro has introduced a new structural equation modeling (SEM) platform to its suite of multivariate methods of analysis. Utilizing their graphical user interface, JMP Pro has created a SEM platform that is easily navigable for both experienced and novice SEM users. As a new platform, JMP Pro does not have the capacity to implement certain…

Many experimental designs in educational and behavioral research involve at least one level of clustering. Clustering affects the precision of estimators and its impact on statistics in cross-sectional studies is well known. Clustering also occurs in longitudinal designs where students that are initially grouped may be regrouped in the following…

Using a representative longitudinal survey of Texas high school seniors who graduated in 2002, we investigate how college postponement is associated with four-year college expectations and attendance--focusing both on the length of delay and the pathway to the postsecondary system. Like prior studies, we show that family background and student…

Parents play an important role in influencing adolescent health behaviors and parenting practices may be an important pathway through which social disadvantage influences adolescent health behaviors that can persist into adulthood. This analysis uses the National Longitudinal Study of Adolescent Health to examine how parenting practices mediate…

Guided by theories and empirical research on intergenerational relationships, we examine the phenomenon of grandparents caring for grandchildren in contemporary China. Using a longitudinal dataset (China Health and Nutrition Survey), we document a high level of structural and functional solidarity in grandparent-grandchildren relationships.…

In longitudinal studies, investigators often measure multiple variables at multiple time points and are interested in investigating individual differences in patterns of change on those variables. Furthermore, in behavioral, social, psychological, and medical research, investigators often deal with latent variables that cannot be observed directly…

Behavioral genetic research has revealed that biogenic factors play a role in the development of antisocial behaviors. Much of this research has also explicated the way in which the environment and genes may combine to create different phenotypes. The authors draw heavily from this literature and use data from the National Longitudinal Study of…

This paper presents the findings from a follow-up quantitative analysis of the Community College of Baltimore County's Accelerated Learning Program (ALP). The results suggest that among students who enroll in the highest level developmental writing course, participation in ALP is associated with substantially better outcomes in terms of English…

There has been a discernable focus within many Australian industries on improving the rates of completion amongst their apprentices and trainees. This paper outlines the results of a study which involved a multivariate analysis of data relating to apprenticeship and traineeship completion, derived from a database developed by the Victorian…

The relationship between ageing and skills is becoming an important policy issue, not least in the context of population ageing. Data from the Programme for the International Assessment of Adult Competencies (PIAAC) will potentially add considerably to the understanding of the relationship between ageing and foundation skills. In particular, the…

While Alberta enjoys proven high, world-class results in student achievement, raising high school completion rates is one of the top priorities in improving the provincial education system. The 2011-12 targeted high school completion rate is 82% five years after entering Grade 10--a 2.5% increase from the current average rate of 79.5%. The purpose…

This study examined the association between prenatal exposure to cocaine and physiological regulation across the first 7 months of age. Measures of respiratory sinus arrhythmia (RSA) were obtained from 169 (82 cocaine-exposed and 87 nonexposed) infants during baseline periods at 1 month and 7 months of age and during tasks designed to elicit…

The present study prospectively explored the main and interactive effect of negative life events and social support from teachers and classroom peers on depressive symptoms in a sample of 198 (111 females, 87 males) students in a Norwegian senior high school. In the longitudinal multivariate analyses, self-reported depressive symptom levels at…

This study examined the effect of explicit and engaging supplemental early literacy instruction on at-risk kindergarten children's literacy development. Sixty-three kindergarten-aged children who had been ranked in the lowest 20th percentile on basic literacy skills participated in this study (38 treatment). Results reveal that children who…

Using a longitudinal, UK representative sample from the Millennium Cohort Study, the present study examined the effects of socio-economic factors on mother- and teacher-rated behaviour, and the unique and cumulative contribution of both risk and protective factors inherent in children's proximal and distal influences to behaviour during the…
