Year Twelve retention rates have a number of well-known deficiencies that prevent proper comparisons of school completion between school systems. This paper compares secondary school completion rates across Australian states and territories from 1989 to 2002 and adjusts "official" 2002 retention rates to take account of the acknowledged…

Causal effect modeling with naturalistic rather than experimental data is challenging. In observational studies participants in different treatment conditions may also differ on pretreatment characteristics that influence outcomes. Propensity score methods can theoretically eliminate these confounds for all observed covariates, but accurate…

Gender was investigated along with other academic variables as predictors of success in entry-level freshman courses from liberal arts mathematics through calculus. The female students were more successful than the male students in all the courses, but gender became less significant as the sophistication level of the course increased. (Contains 16…

Academic motivation as a predictor of academic performance for college athletes has been debated in the literature. This study examined the utility of academic and athletic motivation as a key variable in predicting academic performance among 211 college athletes at a Division I institution in the Midwest. After controlling for background…

The purpose of the present study was to examine the relationship between oxygen uptake (VO[subscript 2]) and heart rate (HR) responses during rest and exercise in Chinese children and youth and to evaluate the relationships between maximal heart rate (%HRmax), heart rate reserve (%HRR), peak oxygen uptake (%VO[subscript 2]peak), and oxygen uptake…

Identifying factors that help or hinder new executives in "getting up to speed" quickly and remaining with an organization is vital to maximizing the effectiveness of executive development. The current study extends past research by examining extraversion as a moderator of relationships between leader-member exchange (LMX) and performance,…

This paper focuses on whether running away from adolescent residential care facilities is related to having off grounds passes with an adult resource. It was hypothesized that as off grounds passes increased in frequency and duration, runaway behavior would decrease in frequency and duration. Data were collected from two hundred closed client…

Objective: Childhood abuse and other adverse childhood experiences (ACEs) have historically been studied individually, and relatively little is known about the co-occurrence of these events. The purpose of this study is to examine the degree to which ACEs co-occur as well as the nature of their co-occurrence. Method: We used data from 8,629 adult…

This article considers the problem of estimating dynamic linear regression models when the data are generated from finite mixture probability density function where the mixture components are characterized by different dynamic regression model parameters. Specifically, conventional linear models assume that the data are generated by a single…

The increase in litigation by students who are dissatisfied with their assessment, and to a lesser extent the time and monetary costs of student appeals makes it imperative that institutions adopt a robust assessment strategy. The concern of consumers with respect to professional services offered by students after graduation is also an issue. This…

Developmental dyslexia may affect as much as 15% of the population, but the aetiology of the disorder is still being debated. The cerebellar theory of dyslexia proposes that cerebellar dysfunction could lead to the myriad of symptoms seen in dyslexic individuals, both in literacy and non-literacy domains. The cerebellum is crucial to the fluent…

This study reports on development and concurrent validation of a competency instrument to identify potential leaders in a mid-size chemical company. Four competencies were identified: courageous problem solving, perceived energy, networking, and perceived motivation. Four different comparison groups were examined in logistic regression analyses.…

Students inaccurately assess their own skills, especially high- or low-performers on exams. This study assessed whether regression effects account for this observation. After completing the Infection and Immunity course final exam (IIF), second year medical students (N = 143) estimated their performance on the IIF in terms of percent correct and…

This study is focused on preservice early-childhood teachers' attributions about control and responsibility for negative caregiving outcomes. Prior research has linked low perceived control over failed outcomes with harsh care-giving behavior. In this sample of 81 preservice teachers in a pre-kindergarten, Associate-degree program, bivariate…

To evaluate the claim that correct performance on unexpected transfer false-belief tasks specifically involves mental-state understanding, two experiments were carried out with children with autism, intellectual disabilities, and typical development. In both experiments, children were given a standard unexpected transfer false-belief task and a…
