Schoolwide Application of Positive Behavior Support in an Urban High School:. Journal Of Positive Behavior Interventions

Abstract: The nuances of the application of schoolwide positive behavior supports (PBS) in an urban high school setting were investigated. Impact of implementation was measured using qualitative interviews and observations, including the School-wide Evaluation Tool (SET), Effective Behavior Support Survey, Student Climate Survey, and office disciplinary referrals. The results indicated that schoolwide PBS was implemented in an urban high school setting with some success. The overall level of implementation of PBS reached 80% as measured by the SET. Staff and teachers increased their level of perceived priority for implementing PBS in their school. A decrease in monthly discipline referrals to the office and the proportion of students who required secondary and tertiary supports was noted. These findings seem to indicate that PBS may be an important process for improving outcomes for teachers and students in urban high school settings

Experiencing space–time: the stretched lifeworlds of migrant workers in India

In the relatively rare instances when the spatialities of temporary migrant work, workers’ journeys, and labour-market negotiations have been the subject of scholarly attention, there has been little work that integrates time into the analysis. Building on a case study of low-paid and insecure migrant manual workers in the context of rapid economic growth in India, we examine both material and subjective dimensions of these workers’ spatiotemporal experiences. What does it mean to live life stretched out, multiplyattached to places across national space? What kinds of place attachments emerge for people temporarily sojourning in, rather than moving to, new places to reside and work? Our analysis of the spatiotemporalities of migrant workers’ experiences in India suggests that, over time, this group of workers use their own agency to seek to avoid the experience of humiliation and indignity in employment relations. Like David Harvey, we argue that money needs to be integrated into such analysis, along with space and time. The paper sheds light on processes of exclusion, inequality and diff erentiation, unequal power geometries, and social topographies that contrast with neoliberalist narratives of ‘Indian shining

Updating reviews: We discussed best practice at the EAHIL 2022 Conference

We conducted a workshop at the EAHIL 2022 Conference which aimed to identify best practice when updating literature searches for systematic reviews. We prepared a presentation and questions which were discussed in small groups. The potential solutions were evaluated using the “rose, thorn, bud” method, and the results of the workshop are summarised here. The importance of transparently reporting the search strategies, platforms, and changes compared to previous searches were emphasised. Workshop participants preferred to change (and improve) previous strategies rather than repeating faulty searches. They also preferred to re-run searches over the whole time period instead of searching from a time point on, suggesting deduplication methods to manage the records. We hope this discussion will continue at future conferences

Smash and Bash Cricket? Affective Technological Innovations in the Big Bash

Focusing on the Australian KFC T20 Big Bash League (BBL), this article explores the innovative televisual technologies that represent T20 cricket as an action packed 'smash and bash' spectacle. An array of innovative technologies is deployed to aesthetically and affectively re-present the BBL. Cameras and microphones are embedded within the field of play, operate in highly mobile and fluid ways, and are framed in close proximity to the action - particularly when placed on the players themselves. The BBL provides intersecting affective layers for viewer engagement built upon tools for analysis, sites of commodification, visual renditions of pseudo-player perspectives and an emphasis on fast-paced entertainment. By constructing degrees of sensory invigoration and vicarious involvement for both casual and invested viewers, these innovative technologies mobilise 'smash and bash' cricket as an affective televisual spectacle

Standards for Ethics in Sport and Exercise Science Research: 2018 Update

In the 21st Century, research opportunities, approaches and environments are in a continual state of flux, and this is also the case for the associated ethical issues. In the original 2009 IJSM editorial [2], we described the ethical considerations embedded into national/international laws and provided specific guidance on the ethical issues which commonly arise in Sports Medicine research. In 2011, this information was updated to recognise the ethical principles of other professional associations and treaties when conducting research involving human participants [3]. Additional information was also provided on the use of Laboratory Animals in research, and on the links between sample size and research ethics. In the second update, published in 2013, we elaborated on the ethical issues relating to the investigation of doping agents; the use of animals for answering research questions that appear to be solely focussed on the enhancement of athletic performance; and sample size in the context of the burden to individual research participants [4]. In 2015, we updated some of the guidelines to account for the changes made to the Declaration of Helsinki in 2013, covered the use of social media in research, provided guidance on how researchers can feed back their incidental and pertinent findings to research participants, covered some of the issues relating to studies involving children, and outlined the difference between a full and pilot study in terms of desired number of participants [5]. In this, our new update for 2018 onwards, we provide the following revisions and additions, labelled with the word “Update” in bold text at various points in this paper; • Clarification of the issues surrounding the use of a gatekeeper for accessing personal data on participants. • Clarification of some of the requirements for research with participants who are either too young to give a valid consent (under relevant local Statute) themselves and/or who lack the mental capacity to give an informed consent. • Clarification of the expectations for the presentation and content of information given to facilitate informed consent/assent. • Highlighting of the obligation to breach confidentiality in certain circumstances and the importance of communicating all relevant process to the potential participant. • Clarification on the use of personal identifiable information including a reminder of the upcoming (May 2018) changes to legislation governing how personal data may be accessed and processed in research in the European Union (https://www.eugdpr.org/). • Provision of advice surrounding the increasing calls for open access data, including the resulting data storage issues. • Update on the ethical and legal considerations involved in secondary analysis (retrospective data) studies. • Clarification on the use of placebos in research. • Coverage of the expectations for studies that involve participant deception (i.e. where fully informed consent is not obtained in advance of participation). • Elaboration of the sample size issues relevant to research ethics. • Coverage of the issues surrounding research on contracted athletes, who are obliged to have data collected on them as part of their contract. • The highlighting of the issues surrounding participant withdrawal from a study • Update on the importance of study registration on a public database and the publication of study protocols • Update on sample size issues, including the recent concerns about reproducibility of study results • Clarification of expectations for the reporting of adverse events/reactions

Systematic review of pre-operative exercise in colorectal cancer patients

The aim of this systematic review was to evaluate the evidence for exercise interventions prior to surgery for colorectal cancer resection. The evidence for use of exercise to improve physical fitness and surgical outcomes is as yet unknown. A systematic search was performed of MEDLINE, EMBASE, CINAHL, AMED and BNI databases for studies involving pre-operative exercise in colorectal cancer patients. Eight studies were included in the review. There is evidence that pre-operative exercise improves functional fitness, and to a lesser extent objectively measurable cardio-respiratory fitness prior to colorectal cancer resection. There is no clear evidence at present that this improvement in fitness translates into reduced peri-operative risk or improved post-operative outcomes. Current studies are limited by risk of bias. This review highlights the common difficulty in transferring promising results in a research setting, into significant improvements in the clinical arena. Future research should focus on which type of exercise is most likely to maximise patient adherence and improvements in cardio-respiratory fitness. Ultimately, adequately powered, randomised controlled trials are needed to investigate whether pre-operative exercise improves post-operative morbidity and mortality
