To date, theoretical and conceptual scholarship on anti-racism has been advanced through leading contributions from several disciplines (e.g., sociology, education, psychology). Still, there remain fewer empirical studies on anti-racism constructs, and we know little about the development of anti-racism among diverse youth across key stages of development. In this special section of Child Development, we sought to address this gap by highlighting scholarship in developmental science that attends to the development of anti-racism in children across contexts (e.g., families, schools) and developmental stages (e.g., early childhood through emerging adulthood). In our introduction to the special section, we review the collective contributions of included studies and outline recommendations for future research in the development of anti-racism in youth. 相似文献

The net neutrality debate is one of several sites of struggles to adapt and redefine rights and obligations of stakeholders in the Internet-centric communications system. Its outcomes will shape the future of the Internet and influence the level and distribution of its benefits. We identify key values that drive the net neutrality discussion and examine the governance mechanisms proposed to achieve these objectives. We find that there is no single policy instrument that allows realization of the range of valued political and economic objectives simultaneously. Contrary to some of the claims advanced in the current debate, safeguarding multiple goals requires a combination of instruments that will likely involve government and nongovernment measures. Furthermore, promoting goals such as the freedom of speech, political participation, investment, and innovation calls for complementary policies. 相似文献

Abstract The aim of this study was to objectively quantify ratings of perceived enjoyment using the Physical Activity Enjoyment Scale following high-intensity interval running versus moderate-intensity continuous running. Eight recreationally active men performed two running protocols consisting of high-intensity interval running (6×3 min at 90% [Vdot]O2max interspersed with 6×3 min active recovery at 50% [Vdot]O2max with a 7-min warm-up and cool down at 70% [Vdot]O2max) or 50 min moderate-intensity continuous running at 70% [Vdot]O2max. Ratings of perceived enjoyment after exercise were higher (P < 0.05) following interval running compared with continuous running (88 ± 6 vs. 61 ± 12) despite higher (P < 0.05) ratings of perceived exertion (14 ± 1 vs. 13 ± 1). There was no difference (P < 0.05) in average heart rate (88 ± 3 vs. 87 ± 3% maximum heart rate), average [Vdot]O2 (71 ± 6 vs. 73 ± 4%[Vdot]O2max), total [Vdot]O2 (162 ± 16 vs. 166 ± 27 L) or energy expenditure (811 ± 83 vs. 832 ± 136 kcal) between protocols. The greater enjoyment associated with high-intensity interval running may be relevant for improving exercise adherence, since running is a low-cost exercise intervention requiring no exercise equipment and similar relative exercise intensities have previously induced health benefits in patient populations. 相似文献

While the female activewear market is growing rapidly, research on activewear consumption and female consumers is lagging. Existing researchers have failed to produce an in-depth understanding of female consumers’ perceptions of activewear, thereby providing limited insights for the activewear industry. Drawing upon brand association theory and the functional, expressive, and aesthetic model, the authors identify important attributes of activewear brands and how attributes lead to benefits pursued by female activewear consumers. Focus groups were conducted with 72 female activewear consumers in Australia. Findings reveal three product-related attributes (functional design, colour, and size and fit) and two non-product-related attributes (price and model imagery) influence the fulfillment of four benefits (mood enhancement, exercise facilitation, healthy and active lifestyle, and physical fit body image). This research contributes theoretical and empirical knowledge about activewear consumption and the vertical structure of brand associations. Findings of this research can help activewear brands deliver benefits to female consumers through improved product designs and marketing strategies. 相似文献

The separation between Church and State, private and public education, is blurring, and coming together, as the government gives families vouchers to attend private and religious schools. Religious groups are starting and supporting their own charter schools, and local jurisdictions (cities and counties) are providing free transportation and food services to children attending private schools. What emerges, and is the focus of this analysis, is the new “middle ground,” a “golden mean,” by which public schools learn diversity and choice while private/religious schools are helped by public programs and funds. The oldest, perhaps, was Lyndon Johnson's compromise with the Catholics to get Title 1 passed as part of the Elementary and Secondary Education Act that sends public school teachers into private schools to help children in need. This study examines the emergence of a middle group in public–private education, and how the policies are working and what's changing. It argues that the child is the center of education, and government and private agencies are changing and should come together to serve the clients, the children. 相似文献
