ABSTRACT Distal-to-proximal redistribution of joint work occurs following exhaustive running in recreational but not competitive runners but the influence of a submaximal run on joint work is unknown. The purpose of this study was to assess if a long submaximal run produces a distal-to-proximal redistribution of positive joint work in well-trained runners. Thirteen rearfoot striking male runners (weekly distance: 72.6 ± 21.2 km) completed five running trials while three-dimensional kinematic and ground reaction force data were collected before and after a long submaximal treadmill run (19 ± 6 km). Joint kinetics were calculated from these data and percent contributions of joint work relative to total lower limb joint work were computed. Moderate reductions in absolute negative ankle work (p = 0.045, Cohen’s d = 0.31), peak plantarflexor torque (p = 0.004, d = 0.34) and, peak negative ankle power (p = 0.005, d = 0.32) were observed following the long run. Positive ankle, knee and hip joint work were unchanged (p < 0.05) following the long run. These findings suggest no proximal shift in positive joint work in well-trained runners after a prolonged run. Runner population, running pace, distance, and relative intensity should be considered when examining changes in joint work following prolonged running. 相似文献

AbstractIn an economic climate when colleges can no longer presume that legislators see institutions of higher learning as tacit public goods, institutions around the country are facing budget cuts. This article presents a case study of the experience of a mid-sized public state university and its Library in a budget crisis undergoing a university-wide program prioritization process. The authors review the process of writing three reports on the Library’s value, along with the approach to engaging staff in the process including a retreat. This article raises questions about what every library should consider assessing and provide tools for libraries navigating similar terrain. 相似文献

ABSTRACT We applied the selection, optimization and compensation (SOC) model of successful aging to media use. Using a new self-report measure to assess selective and compensatory media use we illustrate the role of these media selection strategies in successful aging. In other words, we link compensatory and selective media use to different indicators of well-being among older nursing home residents and for a group of younger adults, which served as a comparison group. Selective media use was positively related to well-being for older, but not for younger adults, and compensatory media use was negatively related to well-being for both younger and older adults. In a second study, we replicated these findings with a sample of healthy older adults. 相似文献

This discussion explores the journal’s special issue from the construct of ownership and how it relates to participatory design. I examine the articles of researchers from Europe and the United States which offer data-centered perspectives and data-driven suggestions. These works suggest how to best involve different stakeholders and I examine how these initiatives can affect participants’ ownership giving voice to change for the future. 相似文献

Abstract Supporting global health priorities through the development of robust health science librarianship partnerships is of significant importance. Increased demand for synthesizing evidence-based information, collating quality resources, and increasing research productivity to improve human health requires integration of library and information science skills and expertise. The Health Sciences Library (HSL) at the University of North Carolina at Chapel Hill (UNC), exists to be an indispensable partner in health information and knowledge, teaching and learning, and research. As global efforts at UNC expanded, the HSL sought to ensure that our global engagement strategy and integration were aligned with campus priorities and partner needs. The HSL created a global research partnership plan: identify resources that improve efficiency, increase access to information, build in-country capacity and expertise—all while strengthening collaborations across multiple countries. Creating a meaningful and sustainable engagement strategy was central to envisioning our path forward and can be used as a framework for consideration by librarians in similar settings. 相似文献

ABSTRACTThe shifting constitution of journalists as humanitarian actors has profound implications for changing forms of journalism practice, as well as for the normative models through which journalists understand and reflect on that practice. In an effort to develop a more empirically-grounded engagement with change, this article explores the interview testimonies of Australian journalists who cover international and humanitarian issues. It argues that frameworks reliant on stark oppositions (between past and present, optimism and pessimism, or moral agency and material structure) are both empirically and practically problematic, and seeks to move beyond these. Engagement with data from semi-structured interviews offers insight into how journalists’ perceptions of and responses to change are shaped by the historical and shifting institutional relations in which they are implicated. 相似文献

The biotechnology industry is a striking example of the disconnect between the location of knowledge creation and its commercial development. I argue that national technological performance in biotechnology is critically affected by institutions governing scientific careers, which shape the professional identities and boundary-spanning activities of research scientists. I test this in a comparison of the United States and France. Drawing on fieldwork and analysis of patent data, I compare institutional frameworks and estimate models of forward patent citations. The models show that entrepreneurial firms are associated with high-performing innovations in this sector whereas large established firms perform poorly in both countries, and highlight the importance of institutions in creating country-specific combinations of human capital with organizational capabilities. 相似文献
