The objective of this systematic review and meta-analysis was to evaluate the effectiveness of peers to deliver programs or encourage older people to be physically active and improve physical outcomes. Peer reviewed articles published in English between January 1976 and June 2016, retrieved from six databases according to the predefined inclusion criteria were included. Where possible results were pooled and meta-analyses conducted. Eighteen articles were included in the review, a total of 3,492 intervention participants, average age 66.5 years and 67.1% were female. Overall, study quality was medium to high. Interventions mainly included resistance, flexibility and cardiovascular training, however there was one aquatic exercise group. Eight studies were delivered by peers and five utilised peer support, which included advice and being positive but was not directly linked to an exercise intervention. While 16 of the 18 studies reported improvement in levels of physical activity and/or noted physical benefits by peer involvement, the meta-analyses findings supported the control groups for the six-minute-walk-test and the timed-up-and-go test. Findings from this review suggest exercise programs involving peers can promote and maintain adherence to exercise programs. However, results were inconclusive as to whether peers have a positive effect on improving older people’s physical function. 相似文献

The purposes of this study were to examine: 1) the potential muscle-specific differences in voluntary electromechanical delay (EMD) and relaxation electromechanical delay (R-EMD), and 2) the effects of intensity on EMD and R-EMD during step incremental isometric muscle actions from 10 to 100% maximal voluntary isometric contraction (MVIC). EMD and R-EMD measures were calculated from the simultaneous assessments of electromyography, mechanomyography, and force production from the vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF) during step isometric muscle actions. There were no differences between the VL, VM, and RF for the voluntary EMDE-M (onsets of the electromyographic to mechanomyographic signals), EMDM-F (onsets the mechanomyographic to force production), or EMDE-F (onsets of the electromyographic signal to force production) as well as R-EMDE-M (cessation of electromyographic to mechanomyographic signal), R-EMDM-F (cessation of mechanomyographic signal to force cessation), or R-EMDE-F (cessation of electromyorgraphic signal to force cessation) at any intensity. There were decreases in all EMD and R-EMD measures with increases in intensity. The relative contributions from EMDE-M and EMDM-F to EMDE-F as well as R-EMDE-M and R-EMDM-F to R-EMDE-F remained similar across all intensities. The superficial muscles of the quadriceps femoris shared similar EMD and R-EMD measurements. 相似文献

The library profession is a strong and vocal proponent of increased information access for people with disabilities. With the discipline's longstanding interest in the subject of services to people with disabilities, questions arise about how the profession perceives the phenomenon. How is library and information science (LIS), as a discipline, conceptualizing disability and accessibility? A content analysis of the LIS literature was conducted to examine this question. The literature provides a fertile ground for study as it reflects the profession's approaches to, and perceptions of, a topic. This research identifies the major issues and trends in the research about accessibility and disability in the LIS literature throughout a 10-year period, 2000–2010. The strongest theme in the literature is accessibility as it relates to web, database, and software, while the prevailing disability of focus is visual disabilities. The overall environment emphasizes technology more than attitudinal aspects associated with disabilities. The research could benefit from increased direct participation of people with disabilities. 相似文献

ABSTRACT This article highlights key events in the relationship between OCLC Online Computer Library Center, Inc. and the Dewey Decimal Classification (DDC) system. The formal relationship started with OCLC's acquisition of Forest Press and the rights to the DDC from the Lake Placid Education Foundation in 1988, but OCLC's research interests in the DDC predated that acquisition and have remained strong during the relationship. Under OCLC's leadership, the DDC's value proposition has been enhanced by the continuous updating of the system itself, development of interoperable translations, mappings to other schemes, and new forms of representation of the underlying data. The amount of categorized content associated with the system in WorldCat and elsewhere has grown, as has worldwide use of the system. Emerging technologies are creating new opportunities for publishing, linking, and sharing DDC data. 相似文献

Sexual harassment remains a persistent workplace problem. The 2017 #Metoo movement and what-have-come-to-be routine news stories about sexual hostility, sexual assault, and sexual harassment in American organizations have opened wounds and reinvigorated public commentary. Although the Equal Employment Opportunity Commission sets forth guidelines for organizations to follow, questions remain about what counts as sexual harassment, and what is an organization’s responsibility in maintaining a harassment-free workplace for its employees. At the invitation of the editor, seven organizational communication scholars responded to a series of questions addressing seven issues related to sexual harassment. These are: sexual harassment policy and training; the responsibilities of bystanders of sexual harassment; organizational culture that provides more support to the harasser than the harassed; the intersection of race with sexual harassment; same-sex harassment and female-to-male harassment; and what can be learned from public movements (e.g. #Metoo). The co-authors’ responses describe sexually harassing situation with which they are familiar. 相似文献
