Responsiveness of the anterior cruciate ligament – Return to Sports after Injury (ACL-RSI) and Injury – Psychological Readiness to Return to Sport (I-PRRS) scales

ABSTRACT

The ACL-Return to Sport after Injury (ACL-RSI) and Injury-Psychological Readiness to Return to Sport (I-PRRS) scales were developed to assess psychological factors associated with return to sports. Validity and reliability have been determined. The aim of this study was to investigate the responsiveness of the Dutch ACL-RSI and I-PRRS. Seventy patients with ACL reconstruction completed both scales twice 2 months apart, plus a Global Rating of Change (GRC) questionnaire. Distribution and logistic regression-based methods were used to study responsiveness. The Standardized Response Mean (SRM) for the ACL-RSI was 0.3 and for the I-PRRS 0.1, indicating low responsiveness. The minimally important change (MIC) for ACL-RSI was 2.6 and for the I-PRRS 0.9. Since the standard error of measurement (SEM) and smallest detectable change (SDC) were larger than MIC in individual patients, it does not seem possible to distinguish minimally important changes from measurement error in individual patients with either scale. At the group level responsiveness seemed sufficient; hence, both scales can be used to investigate the effectiveness of an intervention at the group level. Both scales can also be used in cross-sectional research and in clinical practice as screening instruments to identify patients at risk of not returning to sports.     

Academic careers and the valuation of academics. A discursive perspective on status categories and academic salaries in France as compared to the U.S., Germany and Great Britain

This article explores the changing dynamics between gender, cultural capital and the state in the context of higher education expansion in contemporary China. With a particular focus on the one-child generation and women’s opportunities and aspirations, I draw upon empirical evidence from a first-hand survey study and in-depth semi-structured interviews with female undergraduates from one-child families in 2007. The findings from the survey study suggest that singleton status might mediate the impact of socioeconomic status and cultural capital on students’ academic performance and elite opportunities. The qualitative interview data provide further evidence on how singleton women’s aspirations are related to their socioeconomic and cultural backgrounds. The most significant finding is concerned with singleton girls’ strategy of applying for Chinese Communist Party membership as a way to minimize their social and gender disadvantages. I argue that there emerges a bottom-up approach of women empowerment through qualifications and political selection during China’s transition. Political selection is dressed up in seemingly meritocratic selection, thus becoming more appealing to female undergraduates who, in turn, take advantage of party membership to add a silver lining of political loyalty to higher education qualifications.     

Multiplying the origins of mass schooling: an analysis of the preconditions common to schooling and the school building process in Sweden, 1840–1900

The emergence of mass schooling is undoubtedly one of the most significant transformations that took place during the eighteenth and nineteenth centuries. This article takes a new approach to this fundamental issue by analysing the historical conditions required for the construction of school buildings and the advent of mass schooling, in the 1840–1900 period. Using the school building process as a point of departure, the growth of schooling is tied not only to well-known factors such as industrialisation, state formation processes and the decentralisation of school systems, but also to the expansion of the market economy, modernisation of the credit market, liberalisation of the real property market, changes in local tax systems, and the expansion of the building materials market. Thus, a broader and largely novel explanation of the emergence of mass schooling is accomplished.     

Teaching multiplication to low math performers: Guided versus structured instruction

The results of an intervention program forstudents with difficulties learning mathematicsare reported. Two kinds of math intervention,guided versus structured instruction, werecompared to regular math instruction. A totalof 75 students from regular and specialeducation, aged seven to thirteen,participated. Ability and automaticitymultiplication tests were administered beforeand after the four-month training period. Theresults show that the students in both of theexperimental conditions improved more than thestudents in the control condition. Someadditional differences were found between thetwo experimental interventions. Guidedinstruction appeared to be more effective forlow performing students than structuredinstruction and especially for those studentsin regular education. Special educationstudents appear to benefit most from structuredinstruction for the automaticity ofmultiplication problems. A three monthfollow-up test showed the acquired knowledge tobe well-established in both groups.
