OBJECTIVE: This paper explores the characteristics associated with decisions to adopt or discontinue the use of filtering software, including a critical analysis of some explanations about why it is used or not used in households with children and adolescents. METHOD: This study consisted of a national telephone survey of households in the United States with youth (10 and 17 years) who use the Internet regularly. Interviews were completed with one youth in the appropriate age group and a parent or caretaker. RESULTS: Thirty-three percent of parents reported using filtering or blocking software, with an additional 5% having discontinued its use within the past year. Parents were more likely to adopt filtering software if they had younger children (10--15 years), a high level of concern about exposure to sexual material on the Internet, more extensive knowledge of what their child did online, low trust in the child's ability to use the Internet responsibly, and if the child used America Online (AOL). Using the Internet for school assignments was associated with not having filtering software. CONCLUSION: Findings suggest the need for (1) evaluation research of filter programs used in a real family context and (2) the development of a variety of strategies to prevent exposure to inappropriate material for youth of different ages.  相似文献

Early childhood education and care (ECEC) policy reflects ideas about childhood, labour force participation, education, the economy and the role of the state. This article spans a period of political change in New Zealand from a left of centre government during the first decade of the twenty-first century to a right of centre government from 2009. It draws on policy evaluations and document analysis to critically examine the shifts in approaches to ECEC policy over this time and the consequences for participants of different policy frameworks. It argues that discourses of children as ‘priority’ have replaced a focus on citizenship, and a swing has occurred away from universal to targeted approaches aimed at encouraging ECEC participation for a few. Recent policies have removed crucial professional supports and qualification goals for teachers, bringing into question New Zealand's commitment to quality. The market continues to determine provision and unfettered expansion of for-profit provision is occurring. Yet at odds with this trend, some examples of community planning are occurring, offering a glimmer of possibilities for how ECEC might be conceptualised, organised and supported.  相似文献

Two‐part latent growth models examined associations between two forms of peer status (popularity, likability) and adolescents' alcohol use trajectories throughout high school; ethnicity was examined as a moderator. Ninth‐grade low‐income adolescents (N = 364; Mage = 15.08; 52.5% Caucasian; 25.8% African American; 21.7% Latino) completed sociometric nominations of peer status and aggression at baseline, and reported their alcohol use every 6 months. After controlling for gender, aggression, ethnicity, and socioeconomic status, popularity—but not likability—prospectively predicted alcohol use trajectories. However, these effects were moderated by ethnicity, suggesting popularity as a risk factor for alcohol use probability and frequency among Caucasian and Latino, but not African American adolescents. Results suggest that developmental correlates of peer status should be considered within cultural context.  相似文献

The purpose of this article is to explore efforts to reform physical education programs and to describe why they might not have been successful in the past. The general education and physical education reform literature is examined with attention to the current standards, assessment, and accountability reform movement prevalent in most states. General themes facilitating South Carolina's effort to gain support for policy initiatives and implement a high stakes assessment program are developed with attention to the political activities essential to gain support for change.  相似文献
