ObjectiveTo report findings from a study of anonymous disclosures of abuse experiences among a national sample of youth in Canada who participated in violence prevention programming.MethodsA qualitative analysis was done of a purposeful sample of 1,099 evaluation forms completed following Red Cross RespectED violence prevention programming delivered between 2000 and 2003. Forms were selected based on program facilitators identifying voluntary, anonymous disclosures by youth participants of neglect and emotional, physical, and sexual abuse. Additional data for this analysis includes 27 interviews and focus groups that were used to understand the context of these disclosures and to engage the help of youth and program facilitators in the interpretation of findings.ResultsWhile this study is exploratory and non-representative in its design, findings suggest high rates of hidden abuse, with less than a quarter of youth with abuse experiences reporting a disclosure. Disclosure patterns vary with boys, youth aged 14–15, victims of physical abuse, and those abused by a family member being most likely to disclose to professionals or the police. Interviews help to explain the large number of youth who express reticence to disclose to professionals. Specifically, the data show a perception among youth of negative consequences following disclosure.ConclusionsThis data raises questions regarding why youth are reluctant to report abuse to professionals, preferring to cope independently or by confiding in peers. Youth in this study report feeling anxious about disclosing to authorities, fearful of the potential loss of control over decisions which affect them.Practice implicationsFindings suggest that professionals who provide support to young people's own networks of family and friends may help to facilitate youths’ disclosures of abuse. Furthermore, prevention programming that promotes a positive attitude towards disclosure of abuse experiences and provides an anonymous forum (such as an evaluation form) in which to do so is likely to encourage more young people to disclose. 相似文献

Te Whāriki, the New Zealand early childhood curriculum, has received much praise since its introduction in 1996. There is, however, little research evidence about the implementation or effectiveness of the curriculum in early childhood centres. This article raises questions about the structure and content of Te Whāriki. The holistic and integrated nature of the curriculum means that subject content areas (e.g., art, music, science, literacy) can be overlooked. The generalised nature of the guidelines in Te Whāriki on programme planning allows for flexibility but may result in children being provided with an inadequate range of learning experiences. Concerns are also raised about the value of Learning Stories, a novel form of assessment that was designed to align with the approach of Te Whāriki. 相似文献

This paper discusses recent developments in U.S. teacher education that are tied to the global neo-liberal project. The focus is on how changes experienced throughout the world have played out in the U.S. Three areas are addressed in particular: the commodification of teacher education, hyperrationality and increased accountability, and attacks on multicultural education. The paper closes with a look at the future for teacher education in the U.S. 相似文献

Abstract In this paper, we offer a case study of how Conner Prairie Museum recognized its institutional need for change and employed principles of staff empowerment that allowed the museum to adapt to the needs and interests of guests. The result has been a dramatic improvement in visitor satisfaction and learning. To achieve this transformation, Conner Prairie intentionally altered the organizational culture in large and small ways: by reorganizing staff assignments, restructuring staff assessment, and realigning communication between management and front‐line staff in order to empower front‐line staff. This story is not unique to Conner Prairie, but the details illuminate the vital role of empowerment in the process of cultural change. 相似文献

Athens sits in a basin approximately 450 km2 in area, surrounded by mountains and open sea. Anthropogenic emissions in conjunction with the topographical and meteorological conditions can result in high air pollution within the city. The pollutants of concern for athletes competing in Athens 2004 appear to be nitrogen dioxide (NO2), ozone and particulate (PM10) pollution. Exposure to elevated ozone concentrations has been reported to give rise to symptoms that include cough, chest pain, difficulty in breathing, headache, eye irritation and a decrease in forced expiratory volume in one second. All of these effects are likely to impact upon performance, and several studies of cyclists suggest this to be the case. In contrast, the impact of ambient concentrations of NO2 appears to be negligible on normal activities, but at high exercise intensities the impact remains unclear. The use of currently available information and models to predict the effect of ozone and other pollutants on elite athletes is problematical, since such models are based upon significantly lower ventilation rates than those achieved by some elite athletes. In addition, it is already known that the response to ozone can vary somewhat between individuals. Since the individuals who will be competing in Athens are physiologically very different to the participants in most published studies, it is difficult to predict individual responses. There is some evidence to indicate that adaptation to the adverse health and performance effects of ozone can occur, so that performance is partially recovered on re-exposure. The adaptation is not seen in all studies and appears to be dependent on several factors, including the initial sensitivity of the individual to ozone. Antioxidant supplementation has also been shown in some studies to partially ameliorate the adverse effects of ozone by counteracting the oxidative stress mechanism associated with this pollutant. Whether this transfers to performance enhancement per se remains unclear at present. Additional research is required to gain a sound understanding of the effects of a complex mixed air pollution exposure on the pulmonary function and performance of athletes exercising at high work intensities. 相似文献

AbstractThe purpose of the present study was to relate 3D acceleration patterns of the lower and upper trunk during running to running gait cycle, assess the validity of stride duration estimated from acceleration patterns, investigate speed-dependent changes in acceleration, and examine the test–retest reliability of these parameters. Thirteen healthy young men performed two running trials each on a treadmill and on land at three speeds (slow, preferred, and fast). The 3D accelerations were measured at the L3 spinous process (lower trunk) and the ensiform process (upper trunk) and synchronised with digital video data. The amplitude and root mean square of acceleration and stride duration were calculated and then analysed by three-way analysis of variance to test effects of running conditions, device location, and running speed. Bland-Altman analysis was used to evaluate the test–retest reliability. Marked changes in acceleration were observed in relation to foot strike during running. Stride durations calculated from the vertical accelerations were nearly equal to those estimated from video data. There were significant speed effects on all parameters, and the low test–retest reliability was confirmed in the anterior–posterior acceleration during treadmill running and the anterior–posterior acceleration at slow speed during treadmill and overground running. 相似文献

This study examined the strength of tracking sport participation from childhood to early adulthood among the Dunedin Multidisciplinary Health and Development Study cohort. Participation in sport, dance, or gymnastics as part of a club or group (outside of school) was assessed at ages 7, 9, 15, 18, and 21 years. In addition to the traditionally used correlation coefficients, summary statistics (intraclass correlations; ICC) from random effect models and stability coefficients from generalized estimating equations (GEE) were calculated using all the longitudinal data and controlling for the influence of covariates on tracking strength. Correlation coefficients revealed statistically significant tracking of club sport participation (7–21 years) at low levels (r = .07–0.28). The ICC summary statistic (0.23) was consistent with this, while the GEE suggested moderate tracking (0.59). The results of this study suggest that encouraging sport participation during childhood and adolescence may result in a modest increase in the likelihood of participation later in life. However, the substantial movement into and out of sport participation observed here and in other studies cautions against relying solely on sport promotion among youth as a strategy to promote lifelong participation. 相似文献
