‘Borrowed access’ – the struggle of older persons for digital participation

This study investigates older persons engagement with digital interfaces as one important way to social inclusion. Digital exclusion and social exclusion are intrinsically intertwined, which put older persons at risk for exclusion. To construct meaningful educational practices for inclusion, more insight is needed to understand consequences of low digital competence. Eighteen men and women (retired) have been interviewed about their everyday encounters with digital interfaces. Results show how older persons ‘borrow’ knowledge from social networks or from contacts at previous workplace, to access technology and digital practices. Data also show a common acceptance of exclusion and changes in lifestyle. These fragile chains, put together to access digital practices jeopardise social inclusion understood as autonomy and participation in society. Informants did not mention community arrangements as resources for access and knowledge, which indicate that hard work is required to promote inclusion of this group. A possible way could be using the power of informally framed learning scenarios. Society cannot turn a blind eye to the fact that groups of citizens are hindered from developing capabilities to maintain a social life, to access the health sector, to enjoy integrity and independence and cultural recreation – to live a capable life.     

Associations between individual and collective efficacy beliefs and students' bystander behavior

This study examined whether defending and passive bystanding during peer victimization episodes were associated with individual- and classroom-level efficacy to stop peer victimization. Self-report survey data were analyzed from 1,467 Swedish fourth-grade students (mean age = 10.55) from 100 classrooms in 63 schools. Multilevel analyses revealed that, when witnessing peer victimization, students more often defended victims if they were high in defender self-efficacy and if they belonged to classrooms high in collective efficacy. In contrast, students were more likely to remain passive if they were low in defender self-efficacy and if they belonged to classrooms low in collective efficacy. Taken together, our findings suggest that efficacy beliefs both at the individual and at the classroom level contribute to explaining variability in students' bystander behaviors, which has potential implications for prevention and intervention work.     

Yoga for seniors: understanding their beliefs and barriers to participation

ABSTRACT

Yoga has been found to provide numerous health benefits to older adults including preventing or slowing physical frailty and subsequent functional limitations. The purpose of this study was to examine pre-frail or frail older adults’ beliefs about yoga as well as to identify barriers to participation. We recruited 37 older adults from a Faint, Fall, and Frailty Clinic at a medical center and asked them to complete questionnaires regarding their physical health and beliefs about yoga using the Beliefs About Yoga Scale. Frailty and fall risk were obtained through electronic health records. Participants’ had mean age of 72.81 years. Participants were considered to be prefrail (66.7%) or frail (33.3%), and most (78.4%) had fallen at least once in the past year. Over 72% of participants engaged in light physical activity. The BAYS mean score was 59.17 (SD = 12.5; Range 11–77). Higher scores indicted more optimistic beliefs about yoga. Over 90% of participants had not practiced yoga, 97.1% had no intentions to practice, 61.8% did not know locations placed where yoga classes were offered, 82.4% were unsure about the costs associated with yoga, and only 56.3% reported having transportation. The three primary barriers to practicing yoga were perceived difficulty of yoga practice, lack of motivation, and fear of injury. Participants held positive beliefs about yoga, yet had limited experience and little intention to participate indicating a need to provide targeted educational interventions to this population of older adults.

Energy turnover during 24 hours and 6 days of adventure racing

Abstract

Energy turnover was assessed in two conditions of mixed ultra-endurance exercise. In Study 1, energy expenditure and intake were measured in nine males in a laboratory over 24 h. In Study 2, energy expenditure was assessed in six males during an 800-km Adventure race (mean race time 152.5 h). Individual correlations between heart rate and oxygen uptake ([Vdot]O₂) were established during pre-tests when kayaking, cycling, and running. During exercise, energy expenditure was estimated from continuous heart rate recordings. Heart rate and [Vdot]O₂ were measured regularly during fixed cycling work rates to correct energy expenditure for drift in oxygen pulse. Mean energy expenditure was 18,050 ± 2,390 kcal (750 ± 100 kcal · h^?1) and 80,000 ± 18,000 kcal (500 ± 100 kcal · h^?1) in Study 1 and Study 2 respectively, which is higher than previously reported. Energy intake in Study 1 was 8,450 ± 1,160 kcal, resulting in an energy deficit of 9,590 ± 770 kcal. Body mass decreased in Study 1 (?2.3 ± 0.8 kg) but was unchanged in Study 2. Fat mass decreased in Study 2 (?2.3 ± 1.5 kg). In Study 1, muscle glycogen content decreased by only 60%. Adventure racing requires a high energy expenditure, with large inter-individual variation. A large energy deficit is caused by inadequate energy intake, possibly due to suppressed appetite and gastrointestinal problems. The oxygen pulse, comparing start to 12 h of exercise and beyond, increased by 10% and 5% in Study 1 and Study 2 respectively. Hence, estimations of energy expenditure from heart rate recordings should be corrected according to this drift.     

Integrating expanded school mental health programs and school‐based health centers

This article provides background on national movements toward expanded school mental health (ESMH) programs and school‐based health centers (SBHCs), and presents advantages and challenges of joining these two systems of child and adolescent health care. Delivering ESMH through SBHCs promotes an interdisciplinary approach, health–mental health care integration, and benefits including enhancing referral bases, improving screening of problems, and enhanced confidentiality and privacy. But this integrated approach also presents challenges including managing referrals and significant needs, handling crises, building a focus on prevention and mental health promotion, handling administrative demands, and coping with limited resources. These challenges, ideas for overcoming them, and future directions for this promising service delivery approach are discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 297–308, 2003.     

A catalytic and evolutionary approach to horizontal technology policies (HTPs)

This paper presents an evolutionary framework for horizontal technology policies (HTPs) especially market-friendly ones involving project-based incentives (e.g. R&D project based grants rather than tax-based incentives to yearly expenditures on R&D). HTPs are a category of technological policies whose objective is to promote technological development per se, and associated management and organizational routines, irrespective of industrial branch or technological area. They are being increasingly adopted by both advanced countries and newly industrialized countries in response to the new opportunities and threats opened up by the technological revolution and by the processes of liberalization and globalization; and they complement the more specific and well-known selective and vertical policies aimed at individual sectors and technologies. The analysis is conducted within a learning-to-innovate framework with emphasis on collective, organizational learning; search; and market-building. The outcome is a technology policy cycle with distinct infant, growth, and mature phases. Proactive ‘generation’ of a critical mass of projects for efficient learning and diffusion of innovation routines becomes the aim of the infant phase; while the mature phase of the policy should focus on policy restructuring including drastic reductions in the support of routi projects and enhanced support of more complex types of innovation. The paper also emphasizes the importance of a neutrality component in incentives in the infant phase of increasing selectivity; and of building policy capabilities for efficient policy design and implementation.
