The article reports on a study investigating influences on Australian politicians’ decision making for early childhood education and care (ECEC) policy. The astronomical concept of dark matter is utilised as a metaphor for considering normalising, and therefore frequently difficult to detect and disrupt, influences implicated in politicians’ decision making for ECEC policy. The concept of dark matter connects with and extends Foucauldian conceptualisations of knowledge, power and discourse. The paper argues that maternalist discourses continue to shape the policy landscape for ECEC, though these are largely unacknowledged. 相似文献

The current study examined factors related to older adults’ perceptions of Internet use. Three hundred ninety five older adults participated in the study. The factor analysis revealed four factors perceived by older adults as critical to their Internet use: social connection, self-efficacy, the need to seek financial information, and the need to seek health information. Key differences were found between previous research and the factors extracted in this study. The regression analysis demonstrated that variables like health condition, financial status, computer experience, and life satisfaction significantly predict, at various levels, factors perceived by the older adults to affect Internet use. The significance of the study as well as its implications for research and practice are discussed. Suggestions are made for future research and practice. 相似文献

Jockeys regularly engage in rapid weight-loss practices in preparation for competition. These practices are thought to impair cognitive function, although the evidence in support of this theory remains inconclusive. The purpose of this study was to examine the effects of making-weight on cognitive function in apprentice jockeys in a simulated and competitive environment. Apprentice jockeys (n = 12) reduced their body mass by 4% in 48 h in a simulated environment using weight-loss methods typically adopted in preparation for racing. Simple and choice reaction time, attention, learning and memory were assessed before and after the weight loss. A further 10 apprentice jockeys performed the cognitive function assessment in a competitive racing environment at both a self-reported “normal” and “light” body mass. Hydration status and body mass were assessed in all trials. In the simulated environment, body mass was reduced by 4.2 ± 0.3%, yet no change in cognitive function was observed. Cognitive function also remained unchanged in the competitive environment after a body mass loss of 5.7 ± 1.9%. Typical reductions in body mass in preparation for racing have no effect on cognitive function in apprentice jockeys in a simulated and competitive environment. Further research is required to investigate the physiological mechanisms preventing the adverse effects of making-weight on cognitive function in jockeys. 相似文献
