ABSTRACTThis study compared five different methods for analyzing accelerometer-measured physical activity (PA) in older adults and assessed the relationship between changes in PA and changes in physical function and depressive symptoms for each method. Older adult females (N = 144, Mage = 83.3 ± 6.4yrs) wore hip accelerometers for six days and completed measures of physical function and depressive symptoms at baseline and six months. Accelerometry data were processed by five methods to estimate PA: 1041 vertical axis cut-point, 15-second vector magnitude (VM) cut-point, 1-second VM algorithm (Activity Index (AI)), machine learned walking algorithm, and individualized cut-point derived from a 400-meter walk. Generalized estimating equations compared PA minutes across methods and showed significant differences between some methods but not others; methods estimated 6-month changes in PA ranging from 4 minutes to over 20 minutes. Linear mixed models for each method tested associations between changes in PA and health. All methods, except the individualized cut-point, had a significant relationship between change in PA and improved physical function and depressive symptoms. This study is among the first to compare accelerometry processing methods and their relationship to health. It is important to recognize the differences in PA estimates and relationship to health outcomes based on data processing method.Abbreviation: Machine Learning (ML); Short Physical Performance Battery (SPPB); Center of Epidemiologic Studies Depression Scale (CES-D); Physical Activity (PA); Activity Index (AI); Activities of Daily Living (ADL) 相似文献

This article explores the way in which government policy shapes the lives of young people who are not in education, employment or training (NEET). In particular it examines how the concept of NEETs is set within a specific infrastructure and discourse for managing and supporting young people. The article provides a brief history of the NEET concept and NEET initiatives, before moving on to scrutinise the policies of the Coalition Government. A key distinction is made between those policies and practices that seek to prevent young people becoming NEET from those that seek to re-engage those who are NEET. It is argued that the Coalition has drawn on a similar active labour market toolkit to the previous Labour administration, but that this has been implemented with fewer resources and less co-ordination. It concludes that there is little reason to believe that Coalition policy will be any more successful than that of the previous government, and some reason to be concerned that it will lead to young people becoming more entrenched within NEET. 相似文献

This study explores the opportunities and dilemmas that have been encountered by researchers seeking the views of young people with autism. Twelve researchers were interviewed about their experiences in this field. Through exploration of the complex methodological and ethical issues that they encountered, this study aims to better understand how researchers can improve the way they listen to, and engage with, the views of children and young people with autism. This article discusses four themes that emerged from the interviews: power dynamics; building rapport; communication; and meaningful processes and outputs. 相似文献

OBJECTIVE: This study aimed to establish the views of a group of mental health professionals from various disciplines working in mental health service in a British hospital about the needs of clients who had experienced childhood sexual abuse. METHOD: Staff members were asked to complete an anonymous survey which asked questions relating to knowledge of sexual abuse and its effects, and the needs of clients and staff in working with this client group. A total of 54 people responded to the survey, 42 were female, 11 male. Most (72%) reported having over 10 years experience working in mental health, working in both in-patient and out-patient settings. RESULTS: While respondents were reasonably knowledgeable about childhood sexual abuse, they were not very comfortable, competent or supported in their work with this client group. There were no differences in responses according to the age or gender of respondents, but less experienced staff were more likely to feel supported. Those that had received training and/or supervision felt significantly more capable in working with this client group. CONCLUSIONS: The study offers some support for the development of specialist training, consultancy and supervision programs for mental health staff in the area of child sexual abuse. 相似文献

In recent years, the advent of low-cost digital and mobile devices has led to a strong expansion of social interventions, including those that try to improve student learning and literacy outcomes. Many of these are focused on improving reading in low-income countries, and particularly among the most disadvantaged. Some of these early efforts have been called successful, but little credible evidence exists for those claims. Drawing on a robust sample of projects in the domain of mobiles for literacy, this article introduces a design solution framework that combines intervention purposes with devices, end users, and local contexts. In combination with a suggested set of purpose-driven methods for monitoring and evaluation, this new framework provides useful parameters for measuring effectiveness in the domain of mobiles for literacy. 相似文献

In terms of international education, the concept of online education seems to be a growing trend. Edxonline.org, Minervaproject.com, and Udacity.com are all new massive online open courses (MOOCs)—education websites similar to Coursera offering students the ability to receive the best education from elite universities entirely online. The most tantalizing promise of a company like Coursera is the role it might play in improving education for the world's have-nots: high school dropouts, the global poor, and those less able to self-teach. 相似文献

This study examined the relationships between perceptions of organizational justice and enacting organizational dissent. Participants were 107 full-time employees working in various organizations. Results indicated that employee perceptions of distributive and interpersonal justice negatively predicted latent dissent, while perceptions of informational justice positively predicted latent dissent. Perceptions of interpersonal justice were the strongest predictor of latent dissent. Perceptions of justice were not related to articulated or displaced dissent. Future research should continue to explore triggering agents of dissent in organizations. 相似文献
