Equity and Advocacy Expectations of Culturally Diverse Families’ Participation in Special Education

The authors contend that the equity and advocacy expectations imbedded in the legal mandate for parent participation in the special education decision-making process directly contradict the hierarchy of professional status and knowledge on which the positivist paradigm of professionalism is based, and are also in conflict with the values held by many families from culturally diverse backgrounds, contributing to low levels of participation and advocacy. They argue the need for professional education to incorporate opportunities for professionals to identify the cultural assumptions imbedded in the field of special education towards more balanced and effective collaboration.     

Comparison of individual and group-based load-velocity profiling as a means to dictate training load over a 6-week strength and power intervention

ABSTRACT

This study compared the effects of dictating load using individual (ILVP) or group (GLVP) load-velocity profiles on lower-body strength and power. Nineteen trained males (23.6 ± 3.7 years) completed a back squat one-repetition maximum (1-RM), load-velocity profiling (LVP), and countermovement (CMJ), static-squat (SSJ) and standing-broad (SBJ) jump tests before and after 6 weeks of resistance training. Participants were randomly assigned to an ILVP, or GLVP intervention with intra-session load dictated through real-time velocity monitoring and prediction of current relative performance using either the participant’s LVP (ILVP) or a LVP based on all participant data (GLVP). Training resulted in significant increases in back squat 1-RM for the ILVP and GLVP group (p < 0.01; 9.7% and 7.2%, respectively), with no group-by-time interaction identified between training groups (p = 0.06). All jump performance significantly increased for the ILVP group (p < 0.01; CMJ: 6.6%; SSJ: 4.6%; SBJ: 6.7%), with only CMJ and SSJ improving for the GLVP group (p < 0.05; 4.3%). Despite no significant group-by-time interaction across all variables, the ILVP intervention induced a greater magnitude of adaptation when compared to a GLVP approach. Additionally, an individualised approach may lead to greater positive transfer to power-based movements, specifically vertical and horizontal jumps.     

Information on the Go: Perspective of Academic Librarians on Use of Social Media in Reference Services

Librarians have different perceptions on the employment of social media in library services. This research focused on investigating the perceptions that academic librarians in Ghana hold about the employment of social media in providing reference and user services. A quantitative research approach employing a Likert-type questionnaire was used in soliciting the views of 99 librarians from six top public and private universities in Ghana on their perspective on the use of social media in providing reference and user services. The findings of the study indicate mixed perceptions on the application of social media in reference and user services. These are variously attributed to lack of skills on the part of librarians to use social media, low bandwidth and poor internet connectivity, and inadequate support/motivation from parent institutions among others. As a result, librarians found the traditional mode of service delivery more comfortable, though they knew the importance of social media in their services. The study recommended, among others, development of skills and sensitization workshops to whip up interest in librarians to use social media in reference and user services.     

The Influence of Experimental Design on the Detection of Performance Differences

We demonstrate the effect of sample and trial size on statistical outcomes for single-subject analyses (SSA) and group analyses (GA) for a frequently studied performance activity and common intervention. Fifty strides of walking data collected in two blocks of 25 trials for two shoe conditions were analyzed for samples of five, eight, 10, and 12 subjects and five, 10, 25, and 50 trials. SSA revealed a greater number of differences (p < .05) than GA for all sample and trial sizes. Increasing sample size resulted in consistent increases in the number of differences for GA; differences for SSA were independent of sample size. Increasing trial size from five to 50 resulted in increased differences for SSA; GA were independent of trial size. Detecting significant differences in group designs is more dependent on the number of subjects, while SSA are more dependent on the number of trials.
