This paper reports the results of two semistructured focus group interviews with 17 retirees that explore the issues these retirees perceived as central to their learning in later life (LLL). Focus is especially placed on the factors leading to their learning interests after retirement. A total of six themes (past experience in adulthood and voluntary work, perception of learning, social support, living alone, self-efficacy, and openness) were identified to be related to learning interest in later life. This study has implications for future research and service planning of LLL in the Chinese population. 相似文献

In this study, we sought to confirm the theoretical framework underlying an Online Graduate Mentoring Scale by establishing the scale’s factorial validity and reliability. Analysis of data received from doctoral students and alumni/ae of the College of Education of one large, online, accredited university reduced the initial theoretical framework from seven to six attributes, and resulted in a revision of the scale. Further research is needed to test the theoretical framework with other relevant populations and to refine the scale itself by reducing skewness and attaining item balance. 相似文献

Abstract Competitive sport has been under increasing discussion as a possible favourable factor in the development of eating disorders among children and adolescents. The aim of this study was to determine the frequency of sport-specific eating disorders, in line with the concept of anorexia athletica. This prospective field study included one experimental group and two control groups (disease and healthy). Fifty-two pre-professional ballet dancers aged 13–20 years were tested for clinical eating disorders, anorexia athletica criteria, eating disorder related psychopathology and self-concept, and were compared with 52 patients with anorexia nervosa and 44 non-athletic controls of the same age. The study was conducted using semi-structured interviews as well as self-report questionnaires. A clinical eating disorder diagnosis was made in 1.9% of the ballet dancers versus 0% of the high school students; anorexia athletica was diagnosed in 5.8% of the dancers versus 2.3% of the students. Ballet dancers scored lower than patients with anorexia nervosa with regard to eating disorder related psychopathology and higher than the patients with regard to self-concept. We conclude that more sensitive tools to differentiate between sport-specific (eating) patterns, anorexia athletica and clinically relevant eating disorders are needed, especially for aesthetic sports such as ballet. It remains an important goal to identify athletes with symptoms of anorexia athletica irrespective of their physique and/or sport. 相似文献

In the Ballabeina study, we investigated age- and BMI-group-related differences in aerobic fitness (20 m shuttle run), agility (obstacle course), dynamic (balance beam) and static balance (balance platform), and physical activity (PA, accelerometers) in 613 children (M age = 5.1 years, SD = 0.6). Normal weight (NW) children performed better than overweight (OW) children in aerobic fitness, agility, and dynamic balance (all p <.001), while OWchildren had a better static balance (p < .001). BMI-group-related differences in aerobic fitness and agility were larger in older children (p for interaction with age = .01) in favor of the NW children. PA did not differ between NW and OW (p > or = .1), but did differ between NW and obese children (p < .05). BMI-group-related differences in physical fitness can already be present in preschool-age children. 相似文献

This study investigated how 4‐month‐old infants represent sequences: Do they track the statistical relations among specific sequence elements (e.g., AB, BC) or do they encode abstract ordinal positions (i.e., B is second)? Infants were habituated to sequences of 4 moving and sounding elements—3 of the elements varied in their ordinal position while the position of 1 target element remained invariant (e.g., A B CD, C B DA)—and then were tested for the detection of changes in the target’s position. Infants detected an ordinal change only when it disrupted the statistical co‐occurrence of elements but not when statistical information was controlled. It is concluded that 4‐month‐olds learn the order of sequence elements by tracking their statistical associations but not their invariant ordinal position. 相似文献

One aspect of the increasing position of sustainability in higher education is establishment of distinct interdisciplinary environment-oriented programs. The point-of-departure of this study is differentiation between teaching- and non-teaching-oriented students, in view of their different respective professional roles in society. The motives and environmental literacy (EL) of incoming students were investigated in three types of sustainability programs in Israel: undergraduate teacher-training, graduate teacher-education and graduate non-teacher programs. For all students acquiring knowledge was the major motive for studies. Undergraduate student-teachers demonstrated the least developed EL, although it is slightly higher than that found for incoming student-teachers a decade ago. Graduate teacher-students displayed strong identity as educational agents-of-change and role-models; however, their limited environmental-knowledge raises questions concerning providing knowledge foundations in undergraduate teacher-training programs, indicating the necessity to supplement this in graduate teacher-programs. Graduate non-teacher students perceive their continuing sustainability-oriented studies as a means for developing an environmental career and enter these programs relatively environmentally-literate. The implications focus on necessary components and characteristics of sustainability-programs directed to teaching- and non-teaching-oriented students. These include the necessity to strengthen the environmental-knowledge component in programs directed to teachers; and embed opportunities for professional internships within graduate programs for non-teachers seeking environmental careers. 相似文献

This study examined if accelerometer-based assessments of physical activity were responsive to changes in physical activity level commensurate with performing structured versus unstructured activity in youth. Youth (6–16 years; N = 206) participated in a simulated after-school program that included structured and unstructured games on four occasions over a 3-year period. Recruitment occurred in 2007/2008 and data collection ended in 2011. Participants wore an Actigraph GT1M accelerometer on the hip. The Evenson cut-points were used to determine the time spent in each physical activity intensity, and standardized response means (SRM) were calculated and converted to standard effect sizes to be interpreted according to Cohen’s guidelines. SRMs ranged from trivial (0.16) to high (2.07), with the majority (75%) being classified as moderate or high. Our findings suggest that accelerometry was sensitive to differences in physical activity associated with structured compared to unstructured play, supporting the utility of accelerometry in evaluating activity-promoting interventions. 相似文献
