This study examined the relationship between sit-to-stand (STS) power and physical function in adults with severe obesity. Thirty-eight adults (age: 44 ± 12 years; body mass index [BMI]: 45.2 ± 7.8 kg/m2) completed evaluations of STS power, strength and functional performance. STS power was measured with a wearable inertial sensor, strength was assessed with the isometric mid-thigh pull, and function was measured with the timed up-and-go (TUG), six-minute walk test (6MWT) and 30-s chair STS. Power and strength (normalised to body mass) entered regression models in addition to age, gender, BMI and physical activity (daily step count). Power displayed large univariate associations with TUG (r = 0.50) and 30-s chair STS (r = 0.67), and a moderate association with 6MWT (r = 0.49). Forward stepwise regression revealed that power independently contributed to TUG (β = ?0.40, p = 0.010), 30-s chair STS (β = 0.67, p < 0.001) and 6MWT performance (β = 0.27, p = 0.007). Power also appeared to be a superior determinant of function compared with strength. Power generated via the STS transfer largely underpins the ability to perform functional tasks in adults with severe obesity, although intervention studies are required to investigate a potentially causal relationship. 相似文献

Government statistics show that children with special educational needs and disabilities do not achieve as well academically as their peers, which impacts on later employment and socioeconomic circumstances. Addressing these inequalities is a key policy area which currently lacks a satisfactory evidence base. To explore the issue, the present study used data from the Scottish Longitudinal Study which contains data from the 1991, 2001 and 2011 censuses along with other administrative data, from a representative sample of the Scottish population. Using this large and longitudinal sample, the present study examines educational engagement, expectations and attainment for children with self-reported disability, controlling for other early childhood factors. The results show that children with mental health problems were at higher risk of leaving school early, and that children with learning difficulties were less likely to gain advanced qualifications. Neither limiting long-term illness in early childhood nor disability in adolescence were significant predictors of engagement, however, they did predict measures of academic expectation and attainment. Results suggest there is a critical phase for attainment, with area deprivation in early childhood but not adolescence being important for later educational inequalities. 相似文献

In this paper, the author argues that there is some inevitability to the educational use of computers both in the First and the Third World. One of the issues that will be re-examined as a result of the spreading of computer technology into education will be the distinction between non-formal, formal and informal education. Distinctions between these three modes of educational transmission are usually made on the basis of (i) the type of learning and instruction involved, (ii) the organization of the instruction and learning, and (iii) the purpose or intent of the instructional process. Issues in the educational use of computer technology will affect each of these defining characteristics and present some special challenges to educational managers in the coming decade. The author makes special mention of the implications and challenges for managers in developing educational settings. 相似文献

This virtual issue has been published to mark the CILIP Health Libraries Group 2014 Conference, taking place in Oxford on 24th and 25th July 2014. The issue's theme is to highlight the key role of the health information professional and it shines a spotlight on professional expertise, demonstrating what we can share and learn from each other. It comprises a collection of articles published in the Health Information and Libraries Journal during the last 2 years but is very much about looking forward. The articles selected embrace three main themes: new ways of working; acquiring new skills and competencies; and fine‐tuning existing skills and practices. The virtual issue mirrors the format of the regular journal, namely a review article, six original articles and the three regular features, covering Dissertations into Practice, International Perspectives and Initiatives and Learning and Teaching in Action. All articles included in this virtual issue are available free online. 相似文献
