The aim of this study was to examine the effect of movement and stretching imagery on increases in flexibility. Thirty volunteers took part in a 4 week flexibility training programme. They were randomly assigned to one of three groups: (1) movement imagery, where participants imagined moving the limb they were stretching; (2) stretching imagery, where participants imagined the physiological processes involved in stretching the muscle; and (3) control, where participants did not engage in mental imagery. Active and passive range of motion around the hip was assessed before and after the programme. Participants provided specific ratings of vividness and comfort throughout the programme. Results showed significant increases in flexibility over time, but no differences between the three groups. A significant relationship was found, however, between improved flexibility and vividness ratings in the movement imagery group. Furthermore, both imagery groups scored significantly higher than the control group on levels of comfort, with the movement imagery group also scoring significantly higher than the stretching imagery group. We conclude that the imagery had stronger psychological than physiological effects, but that there is potential for enhancing physiological effects by maximizing imagery vividness, particularly for movement imagery. 相似文献

This study aimed to determine cross-sectional associations of dog ownership, dog walking, and physical activity (PA) among children and their parents. Objective measures of PA were obtained for children ages 5-6 and 10-12 years from 19 primary schools across Melbourne, Australia. Parents self-reported their PA, dog ownership, and frequency of dog walking: 53% of families owned a dog, 41% of children who owned a dog did not walk their dog at all, and 32% reported never or rarely walking their dog as a family. Dog ownership was associated with an additional 29 min/day in PA among younger girls, and 70 and 59 min/week more in PA among mothers of younger boys and older girls, respectively. Among mothers of older girls, dog owners were 1.6 times as likely to meet PA guidelines. Mothers with older boys and girls, and fathers with younger boys, who reported walking the dog regularly as a family, spent more time in PA (105, 90, and 158 more min/week, respectively). Promoting dog ownership and dog walking among children and as a family are potential strategies for increasing PA participation in some families. 相似文献

This paper examines the gendered representations of scientists in the UK media. Our analysis reveals the asymmetrical ways in which men and women working in science, engineering and technology are portrayed, in particular through the emphasis on women's appearance and a focus on their exceptional status. It also highlights the way female scientists may be used to "sex up" the discipline in the context of increasing concern about the (un)popularity of science. This media analysis is contextualized by drawing on data from 86 scientists examining how women themselves experience press and television coverage and address the cultural contradictions surrounding their role. The research highlights the challenges facing women working in these fields and the dilemmas for those seeking to develop a "human" face for science and promote a positive image for women. 相似文献

This paper argues for a historical analysis of the relationship between teachers and the state. The historical analysis demonstrates the ways in which strategies of teacher management shifted according to circumstances. In the first period, the 1920s, restrictions on teacher autonomy were removed, and ‘indirect rule’ used as a means of moving teachers away from the labour movement. In the second period, after the 1944 Act, a restricted ‘professional’ autonomy was encouraged. In both periods equality of status for teachers as ‘partners’ in the educational enterprise was offered in return for teachers’ acceptance of a limited or licensed professionalism. Current developments in the management of the teaching force suggest that the abandonment of indirect strategies of management may result in a return by teachers to less restricted ‘professional’ behaviour. 相似文献

The importance of early identification of children at risk for reading failure is clearly established in the literature. The purpose of this longitudinal retrospective study was to further define the relationship between the development of prereading skills and later reading outcome in two groups of children; a group of reading‐disabled children and a group of their normally reading peers. Children's alphabetic knowledge, phonological awareness, and rapid naming skills were explored at the beginning of kindergarten and again prior to first grade as a function of later reading outcomes. Results indicate that differences found between the groups in all measures at prekindergarten age diminish by prefirst grade with the exception of phonological awareness abilities. Findings have direct implications for screening children at risk for reading difficulties and the time‐sensitive nature of these tasks during the preliteracy period. 相似文献

Much of the limited literature on organ donation has focused on the demographic and psychographic profiles of people who are willing to become organ donors. More information about the relationship of attitudes, values, knowledge, and actual behavior among adults is needed if targeted communication campaigns promoting organ donation are to succeed. The results of a mail survey of 798 adults sampled (via stratified random sampling procedures) from two local sites of a national corporation suggest that attitudes toward donation, knowledge about organ donation, altruism, and perceived social norms are significantly associated with both actual behavior (having signed an organ donor card) and behavioral intent (among non-donors) to sign a card in the future. These findings support the major models of organ donation willingness, especially those advanced by Horton and Horton (1991) and Kopfman (1994). This study also advances current knowledge of organ donation willingness by 1) using a large, relatively diverse population of adults rather than relying on a student sample; and 2) focusing on specific knowledge barriers that distinguish donors from non-donors. 相似文献
