Estimation of a Nonlinear Intervention Phase Trajectory for Multiple-Baseline Design Data

A multilevel logistic model for estimating a nonlinear trajectory in a multiple-baseline design is introduced. The model is applied to data from a real multiple-baseline design study to demonstrate interpretation of relevant parameters. A simple change-in-levels (ΔLevels) model and a model involving a quadratic function (Quadratic) for the nonlinear intervention phase data were also estimated. In addition, a simulation study was conducted to assess Markov chain Monte Carlo estimation of the logistic model and compare its trajectory recovery with use of the ΔLevels and Quadratic models. While most of the logistic model's parameter values were recovered well, trajectory recovery was very reasonable using the simpler Quadratic model. Results are discussed along with recommendations for practitioners and directions for future research.     

The effect of peer group performance on the self-concept of reading in a foreign language

According to the big-fish-little-pond (BFLP) model, the self-concept is not only influenced in a positive way by one’s own achievement, but also in a negative way by one’s relative achievement in comparison with one’s immediate peers. This study investigates whether the BFLP effect also holds for second language acquisition. A random sample of 9167 Dutch-speaking students from Grade 8 took a reading comprehension test in French followed by a short background questionnaire in which they were asked for their self-concept of reading French. Multilevel regressions of the latter on individual and group achievement confirmed the BFLP effect but did not confirm an interaction of the effect with gender, individual achievement or class size. Moreover, in line with the local dominance hypothesis, it was shown that the negative effect of the average performance of peers is stronger for classmates than for schoolmates.     

Education as a ‘risky business’: Theorising student and teacher learning in complex times

This paper employs sociological literature on risk and the commodification of education to explain current schooling practices in a context of increased concerns about students’ behaviour and results on standardised tests of achievement. Drawing upon teacher and student learning practices in three school sites in south-east Queensland, Australia, the article reveals how specific tests, packages and programmes have been employed as technologies of governance to minimise the risk of adverse student behaviour, maximise student outcomes on standardised tests, and provide teachers with discrete learning experiences construed as improving such outcomes. The sum total of these foci is the construction of education as an increasingly ‘risky business’ which employs a myriad of products and tests to manage perceived and actual risks. The paper also reveals how these products and processes constitute student misbehaviour and inadequate teacher and student learning as ‘risk objects’ requiring constant intervention, but which also inhibit inclusion in schooling settings, and challenge teachers’ professionalism.     

Suprasegmental Phonology Development and Reading Acquisition: A Longitudinal Study

Previous studies implicate suprasegmental phonology in reading acquisition. However, little is known about how suprasegmental sensitivity develops or how it contributes to reading. Here, 130 Spanish primary-school children participated in this 2-year longitudinal study. Nonlinguistic rhythm, lexical-stress sensitivity and metrical-stress sensitivity, along with phonological awareness, vocabulary, nonverbal intelligence, and reading aloud, were assessed on five occasions. Results suggest that prosody abilities have different developmental trajectories and that prosody explains unique variance in reading beyond that explained by other factors. There was some evidence that the contribution of each prosody skill occurred at different phases in reading development. Nonlinguistic rhythm, lexical-stress sensitivity, and metrical-stress sensitivity assessed at the end of kindergarten, the start of Grade 1, and the end of Grade 1, respectively, predicted reading performance 6 months later. Nevertheless, sample size and reliability temper the conclusions that can be made. The implications of prosody skills for literacy development are discussed.     

Analyzing Contemporary Introductory Textbooks on Correctional Administration/Management/Organization: A Content Analysis

This book review essay discusses and analyzes how introductory textbooks on correctional administration, written primarily for the American university market, frame the discourse on this subject matter. The writer presents both quantitative and qualitative empirical evidence of coverage given to prison administration. In addition to traditional content analysis methods, the authors of these books were contacted and asked to explain the decision‐making processes they used for content inclusion, exclusion and/or minimization. The paper concludes with a handful of recommendations on improving texts in this subdiscipline.
