Validity and Reliability of Three Self-Report Instruments for Assessing Attainment of Physical Activity Guidelines in University Students

The purpose of this study was to compare the validity and reliability of three short physical activity self-report instruments to determine their potential for use with university student populations. The participants (N = 155; 44.5% male; 22.9 ± 5.13 years) wore an accelerometer for 9 consecutive days and completed a single-item measure, the a brief two item measure and the International Physical Activity Questionnaire—Short Form questionnaires on day 1 and 9. Correlations between self-reported and accelerometer derived moderate-to-vigorous physical activity levels were moderate for the International Physical Activity Questionnaire—Short Form, while poor for the single-item measure and the a brief two item measure. The agreement level was high with the International Physical Activity Questionnaire—Short Form (77.4%) and moderate for both the single-item measure (45.2 %) and a brief two item measure (44.5 %). The intraclass correlations between the two administrations were moderate to strong across all measures (0.52–0.70) in 133 participants. The International Physical Activity Questionnaire—Short Form is the most suitable of these three self-report instruments for use with this population due to higher correlations and levels of agreement with accelerometry.     

Anti-Market Research: Piracy,New Media Metrics,and Commodity Communities

Over a decade after Napster’s introduction, file sharing programs still shoulder much of the blame for music and other media’s declining sales. Although labels and industry associations point their fingers at the harm digital piracy and file-sharing cause, they are less likely to admit the extent to which these anti-markets inform everyday decisions. File-sharing technologies create networks of users that serve as profitable data for ratings and metrics agencies. Using a case study of BigChampagne and its relationship to Napster, this article considers how the look, structure, and function of file-sharing software helped turn an economically threatening community into a commodity and how piracy’s disruptive potential is always in tension with processes of commodification.     

A brief screening battery for predicting school achievement at ages seven and nine years

This article describes the development, utilization, and evaluation of an early screening battery for predicting school success or failure. The battery was administered to the pediatric population of the Southern California Permanente Medical Group, Panorama City Medical Center, at the time of the routine five-year health examination. For 411 children whose school performance was assessed by the teacher at age seven years, the Caldwell Test was the best predictor, but it had significant value for girls only (p<0.0001). In 1,251 children evaluated at age nine years, the Beery-Butkenica Developmental Test of Visual-Motor Integration (VMI) and the Caldwell Test were the best predictors (p⩽0.003). In 600 children for whom we had teacher ratings at ages seven and nine years, the VMI repeated at age seven years significantly predicted academic achievement and reading at age nine years for girls and boys (p = 0.007). Although combining the academic performance with VMI results at age seven years yielded 89% accuracy of prediction at age nine years, the false-positive rate represents a serious practical problem of mislabeling children as school failures.     

Working towards Inclusive Education: Social Contexts

ABSTRACT

Special education in England has developed over a large number of years, during which changes in philosophy and practice have been charted in Acts of Parliament. Current thinking was given focus by the recommendations of the 1978 Warnock Report, many of which have been implemented. The most recent legislation relates to the establishment of Statements of Special Educational Needs (SEN), the introduction of a Code of Practice, recognition of the role of parents and of the need for multi‐professional cooperation, the integration of children with SEN into mainstream classrooms and the right of access of all children to a broad and balanced curriculum, as articulated in the National Curriculum.
