Reliability of a commercially available and algorithm-based kinetic analysis software compared to manual-based software

There is a need for reliable analysis techniques for kinetic data for coaches and sport scientists who employ athlete monitoring practices. The purpose of the study was: (1) to determine intra- and inter-rater reliability within a manual-based kinetic analysis program; and (2) to determine test-retest reliability of an algorithm-based kinetic analysis program. Five independent raters used a manual analysis program to analyse 100 isometric mid-thigh pull (IMTP) trials obtained from previously collected data. Each trial was analysed three times. The same IMTP trials were analysed using an algorithm-based analysis software. Variables measured were peak force, rate of force development from 0 to 50 ms (RFD50) and RFD from 0 to 200 ms (RFD200). Intraclass correlation coefficients (ICC) and coefficient of variation (CV) were used to assess intra- and inter-rater reliability. Nearly perfect reliability was observed for the manual-based (ICC > 0.92). However, poor intra- and inter-rater CV was observed for RFD (CV > 16.25% and CV > 32.27%, respectively). The algorithm-based method resulted in perfect reliability in all measurements (ICC = 1.0, CV = 0%). While manual methods of kinetic analysis may provide sufficient reliability, the perfect reliability observed within the algorithm-based method in the current study suggest it is a superior method for use in athlete monitoring programs.     

An intensive study of the reliability of Rhode Island Pupil Identification Scale

A recent study of the factorial structure of the Rhode Island Pupil Identification Scale (RIPIS), a pupil behavior-observation scale for use by classroom teachers for detecting young children with learning problems, has led to profile scoring. This study describes the procedures and the results of an intensive and comprehensive investigation of the homogeneity of the subscales and their reliabilities as well as those of the two profiles yielded by the scale. All subscales, profiles, and composites were found to be highly internally consistent and stable over a time interval of five months. The authors also wish to show why complex psychometric scales require that more than cursory attention be paid to reliability issues.     

1968-convention at the top of the nation

The first dwellers in the territory now known as Colorado are thought to have been Folsom Men 15,000 years ago. Denver, "Queen City of the Rockies," was founded by gold-seekers in 1858 at the confluence of the South Platte River and Cherry Creek. Members of the Medical Library Association are invited to come to the 1968 Annual Convention to absorb a little of the Old West and enjoy the New West in a growing modern city.     

A Framework for Evaluating the Consequences Programs of Assessment

How can the enterprise of looking at the consequences of testing in America be moved forward? What are the responsibilities of the key actors? How can we accumulate the evidence that we need?     

Italian students’ results in the PISA mathematics test: does reading competence matter?

In Italy, from the 2003 reports to the present, the National Institute for the Educational Evaluation of Instruction and Training (INVALSI) has conducted research on Programme for International Student Assessment (PISA) results in order to understand Italian students’ low achievement in mathematics. In the present paper, data from a representative sample of 15-year-old Italian students who participated in PISA 2012 were analysed. This study’s primary aim is to verify how students’ linguistic competences are associated with their performance in mathematics. For the evaluation of the impact of item reading demand on students’ performance, we selected 24 mathematics items with a high reading demand and 31 mathematics items with a low reading demand, as classified by Italian language and methodology experts. Repeated measure variance analyses were conducted. The results showed differences in function of gender: females are advantaged in mathematics items with a high reading demand, independent of their level of reading literacy. In contrast, males are advantaged in mathematics items with a low reading demand, independent of their level of reading literacy. Possible policy implications are discussed.     

Regulating global capitalism amid rampant corporate wrongdoing—Reply to “Three frames for innovation policy”

Despite progress in science and technology and the economic prosperity achieved by numerous countries over the past century, contemporary global capitalism has left us with severe grand challenges for the future including rising inequality, global warming, modern slavery, child labor and several other human rights struggles. How can we fix them? For many years, scholars and policy makers alike have believed that economic growth (fueled by innovation) would fix institutional failures and lift people out of human misery. We now know that this story creaks. I would suggest that the current grand challenges are related in a non-trivial way to companies’ wrongful business conduct, especially that of large multinational corporations which have grown to rival governments in size, and have proven to be powerful agents capable of shaping the global governance agenda. I challenge technological determinism and ‘transformative change’ frameworks by arguing that the regulation of global capitalism needs to put powerful private actors at center stage since neglecting them will give rise to yet another generation of dysfunctional development and innovation policies.
