ABSTRACTThe purpose of the study was to assess the validity and inter-bike reliability of 10 Wattbike cycle ergometers, and to assess the test–retest reliability of one Wattbike. Power outputs from 100 to 1000 W were applied using a motorised calibration rig (LODE) at cadences of 70, 90, 110 and 130 rev · min?1, which created nineteen different intensities for comparison. Significant relationships (P < 0.01, r2 = 0.99) were found between each of the Wattbikes and the LODE. Each Wattbike was found to be valid and reliable and had good inter-bike agreement. Within-bike mean differences ranged from 0.0 W to 8.1 W at 300 W and 3.3 W to 19.3 W at 600 W. When taking into account the manufacturers stated measurement error for the LODE (2%), the mean differences were less than 2%. Comparisons between Wattbikes at each of the nineteen intensities gave differences from 0.6 to 25.5 W at intensities of 152 W and 983 W, respectively. There was no significant difference (P > 0.05) between the measures of power recorded in the test–retest condition. The data suggest that the Wattbike is an accurate and reliable tool for training and performance assessments, with data between Wattbikes being able to be used interchangeably. 相似文献

The main aspects of the creation of a monitoring system for the research activities of the members of a higher-education institution are considered. The scientific activities of the lecturers and members of Turgenev Orel State University is used as the basis. It is expected that this system will be an efficient tool for optimal managerial decisions at all levels. 相似文献

The responsibility for and the initiative to preserve electronic journal content is neither clear nor easy, and knowing the preservation status of an e-journal is not a basic step within the NASIG Core Competencies for Electronic Resources Librarians life cycle of electronic resources management. Columbia and Cornell University Libraries secured funding for a project to specifically evaluate strategies for expanding e-journal preservation. A wide range of e-journal categories are evaluated within the scope of the project, including: content direct from publishers, small and society publishers, Open Access e-journals, full-text content from third-party content providers, and university generated e-journals. Discussed are techniques for identifying at risk e-journals, integrating preservation into license negotiation with publishers, tracking the preservation status of e-journals, and developing relationships with existing preservation agencies. The quality of future of scholarship and teaching hinges on the preservation of the scholarly record. 相似文献

Access and Express: Professional Perspectives on Public Library Makerspaces and Intellectual Freedom
Shannon Crawford Barniskis 《Public Library Quarterly》2016,35(2):103-125
This study examines the roles of makerspaces and librarians in public libraries, as defined by nine librarians instituting makerspace services. It explores their understanding of creative spaces and library policy, specifically the foundational principles of intellectual freedom and access. Using constructivist discourse analysis tools, this study analyzes interview data to illuminate a concept of access grounded in expression, incorporating hands-on activities, tools, and social connections. This study has implications for practitioners and policymakers in reconsidering access as a positive liberty enabled by social contexts, and librarians’ enzymatic roles in facilitating those contexts. 相似文献

This study is designed to identify the underlying satisfaction dimensions gained through engagement in target shooting as a serious leisure pastime. The instrument design was based on the Leisure Satisfaction Scale. A total of 5502 useable surveys were collected through the Internet and a website related to target shooting and gun ownership. The results revealed eight dimensions: self-actualization, social interaction, location aesthetic, respite, physical benefit, connection and hedonic pleasure, which supplied the primary satisfiers of engaging in target shooting as a serious leisure activity. The demographic profile and dimensions of satisfaction may serve to dispel commonly held stereotypes of shooting hobbyists and those involved in gun ownership. The findings have important implications for leisure researchers and practitioners, to industry, both leisure and firearm related, and the target shooting community at large. This study adds to the literature of both target shooting and serious leisure. 相似文献

An instrument, Student Survey Questionnaire, assessed the appropriateness of students' social and personal problems for discussion with a counsellor. It was hypothesized that there would be no significant relationship between the social and personal problems of students and the appropriateness of the problems for discussion with a counsellor. It was tested using a 2×5 chi square contingency table of non-admission or admission of problems against five appropriateness levels. The result showed a significant relationship: the more problems the students admit the more they want to discuss them. Most of the students who admitted they have personal and social problems saw these problems as appropriate for discussion with a counsellor. 相似文献

While scholars have increasingly engaged with the (micro)political and emotional experiences of coaches in professional and semi-professional football, little attention has been given to grass-roots coaches’ understandings of these issues. The aim of this paper is to outline one possible research agenda that could contribute to the development of a rich and increasingly nuanced understanding of the everyday realities of being a grass-roots football coach. In particular, we consider (volunteer) coaches’ participation in grass-roots football to be an inherently relational endeavour. Following the presentation of a creative fiction that is based upon our shared experiences of being grass-roots football coaches, we then illustrate how relational thinking might be productively applied to exploring the social, (micro)political and emotional features of grass-roots football coaching. 相似文献

The purpose of this study was to assess the reproducibility of body composition measurements by dual-energy X-ray absorptiometry (DXA) in 12 elite male wheelchair basketball players (age 31 ± 7 years, BMI 21 ± 2 kg/m2 and onset of disability 25 ± 9 years). Two whole body scans were performed on each participant in the supine position on the same day, using Lunar Prodigy Advance DXA (GE Lunar, Madison, WI, USA). Participants dismounted from the scanning table and were repositioned in-between the first and second scan. Whole body coefficient of variation (CV) values for bone mineral content (BMC), fat mass (FM) and soft tissue lean mass (LTM) were all <2.0%. With the exclusion of arm FM (CV = 7.8%), CV values ranged from 0.1 to 3.7% for all total body and segmental measurements of BMC, FM and LTM. The least significant change that can be attributed to the effect of treatment intervention in an individual is 1.0 kg, 1.1 kg, 0.12 kg for FM, LTM, and BMC, respectively. This information can be used to determine meaningful changes in body composition when assessed using the same methods longitudinally. Whilst there may be challenges in the correct positioning of an individual with disability that can introduce greater measurement error, DXA is a highly reproducible technique in the estimation of total and regional body composition of elite wheelchair basketball athletes. 相似文献
