In this paper narratives submitted to this issue are reviewed and critiqued using the feminist lenses of othering and organizational irrationality. Four emergent themes in the narratives are identified and discussed, with the themes and the feminist critique of them used to provide a set of recommendations for developing researcher-IRB working relationships.  相似文献

ABSTRACT

This study aimed to assess the effect of playing surface (Natural [NT] and Artificial [AT] Turf) on the fatigue response to a soccer-specific exercise protocol (SSEP). Eighteen male soccer players completed the SSEP on NT and AT with pre-, post-, and 48 h post-assessments of eccentric knee flexor (eccKF) and concentric knee extensor peak torque (PT), peak countermovement (CMJ) and squat jump (SJ) height, and Nordic hamstring break angle. No significant main effects for surface or any surface and time interactions were observed for any of the outcome measures, except for eccKF PT recorded at 3.14 rad·s-1, which was significantly lower 48 h post-trial in the AT condition (AT = 146.3 ± 20.4 Nm; NT = 158.8 ± 24.7 Nm). Main effects for time were observed between pre- and post-trial measures for eccKF PT at all angular velocities, Nordic break angle, CMJ and SJ height. Nordic break angle, and both CMJ and SJ height were significantly impaired 48 h post-trial when compared to pre-trial. The findings of the current study suggest surface dependent changes in eccKF PT which may have implications for recovery and subsequent performance after competition on AT.  相似文献

This session highlighted trends in continuing resource collections and collection management throughout the 30-year period from 1985 through 2015. Electronic resources became available in the 1990s and grew in prevalence from the 2000s through the present, changing the make-up of library collections and also how libraries measure collections and collection usage. Two librarians and two vendors shared their perspectives on these changes in collection development, describing how library collections now contain a combination of older formats and older ways of collecting data, and new, electronic content and automated ways of collecting and disseminating data about collections.  相似文献

Estimating treatment effects for subgroups defined by posttreatment behavior (i.e., estimating causal effects in a principal stratification framework) can be technically challenging and heavily reliant on strong assumptions. We investigate an alternative path: using bounds to identify ranges of possible effects that are consistent with the data. This simple approach relies on fewer assumptions and yet can result in policy-relevant findings. As we show, even moderately predictive covariates can be used to substantially tighten bounds in a straightforward manner. Via simulation, we demonstrate which types of covariates are maximally beneficial. We conclude with an analysis of a multisite experimental study of Early College High Schools. When examining the program's impact on students completing the ninth grade “on-track” for college, we find little impact for ECHS students who would otherwise attend a high-quality high school, but substantial effects for those who would not. This suggests a potential benefit in expanding these programs in areas primarily served by lower quality schools.  相似文献

The exploratory study focused on describing typical routines of preparing for winter outdoor play with preschool children and their teachers. Naturalistic observations, interviews and photographs resulted in extensive examples of children’s development in cognitive understanding of winter and winter-related concepts. Observations of teachers and assistants revealed task-oriented perspectives including detailed strategies and planning. Asynchronous communication and directive language were typical of teacher/child communication. Photo analyses confirmed physical skills used by preschoolers to accomplish dressing tasks and extensive curricular changes to indoor environments.  相似文献

Abstract

Although transition outcomes for youth with disabilities have shown some improvement and transition support practices have been identified, many young people continue to face transition barriers that preclude their full participation in key adult life activities. While research efforts have largely been professionally driven, there is emerging literature suggesting that the use of participatory, empowerment methodologies may bolster the identification of appropriate research methods and useful solutions to problems, as well as promoting the application of findings to accomplishing practice and policy improvements. The purpose of this study was to use a youth-directed, participatory action methodology to investigate youths' perceptions of the value of transition promotion experiences identified as effective by professionals, and to examine the level at which youth with disabilities participate in those experiences. A survey was developed and administered to 202 young people with disabilities by leaders from the National Youth Leadership Network. Findings indicated that youth generally endorse the importance of validated transition promotion practices; however, they reported having limited opportunity to participate in them. Implications related to the use of participatory action methodologies and needed practice and policy improvements are discussed.  相似文献
