1. 儿童青少年运动员应该食用多样化的食物,其中,蛋白质应占膳食总能量的12%-15%,碳水化合物至少占55%,而脂肪至多占30%。日常生活中如何吃才能满足这些要求呢?膳食指南宝塔提供了一条可行之道。2.有些营养素对热爱运动的儿童青少年运动员非常重要,要保证摄入充足,这些营养素是碳水化合物(包括纤维素)、维生素B6、维生素D、铁、钙、镁、锌、铬。科学合理、包罗各类食物的平衡膳食,对青少年运动员最大程度地全面摄取各种营养素,满足生长发育和运动训练的需要,是非常必要的。3.鼓励儿童青少年运动员在运动训练前、中、后进行补液,以避免脱水的发生。4.如果膳食合理平衡,就没必要额外补充营养品。 相似文献

This article is a preliminary analysis of the first few years of the Computer Matching and Privacy Protection Act of 1988 (CMPPA). The act requires Federal agencies to establish Data Integrity Boards (DIBs) with responsibility to approve written agreements for computer matches in which their agencies are involved. Information for this analysis was collected from the annual reports on computer matching submitted by agencies to the Office of Management and Budget (OMB) for 1990 and 1991 and from 108 matching agreements. The secretaries of several DIBs were also interviewed. The effectiveness of DIBs and matching agreements are analyzed using McCubbins and Schwartz's distinction between “police-patrol” and “fire- alarm” oversight. The article concludes that more active and direct oversight, which would occur through an independent data protection or privacy board, is necessary. 相似文献

任何一门专业都有其用于行业自律的职业道德规范,博物馆也不例外。自1986年国际博协布宜诺斯艾利斯大会通过《博物馆职业道德准则》以来,已被世界上许多国家的博物馆及其专业人员所接受,成为国际博物馆界除《国际博协章程》之外一个最重要的文件。本文作者曾亲自参与该文件的讨论、起草和修订。在文章中,她对上个世纪70年代以来博物馆职业道德形成的社会背景、哲学体系、核心关注、道德与法律的关系以及近年来的最新修订作了较全面的回顾和分析。 相似文献

The Standards Committee of the Veterinary Medical Libraries Section was appointed in May 2000 and charged to create standards for the ideal academic veterinary medical library, written from the perspective of veterinary medical librarians. The resulting Standards for the Academic Veterinary Medical Library were approved by members of the Veterinary Medical Libraries Section during MLA '03 in San Diego, California. The standards were approved by Section Council in April 2005 and received final approval from the Board of Directors of the Medical Library Association during MLA '04 in Washington, DC. 相似文献

The study explored the role of second-screen use and binge-watching in moderating entertainment education (EE) effects. A pretest/posttest experiment of 273 viewers of East Los High measured the effects of exposure to three subplots, concerning alcohol abuse, abortion, and immigration. The effect of identification with characters on change in attitudes was significantly moderated by second-screen use and binge-watching. In particular, second-screening tended to enhance the positive impact of identification; whereas, among respondents who binge-watched the show, the effects of identification were weaker. 相似文献

This article follows an earlier publication highlighting the changing role of special educational needs co‐ordinators (SENCos) in England. SENCos are now required to manage change strategically and deliver inclusive school cultures. School‐based action research undertaken by a teacher studying for the postgraduate National Award for SEN Co‐ordination (NASENCO) is featured in the article; a strategic review of resource allocation increased the availability and quality of interventions for students with special educational needs and disabilities (SEND). The commentary which frames the study acknowledges that many SENCos are not yet members of a senior school management team (SMT) despite their mandated strategic whole‐school remit. Featuring the process through which one SENCo has strived to enhance SEND provision and develop context‐specific key performance indicators brings official guidance on the SENCo's role in strategic change management into sharp focus, raising questions that should concern both SMTs and non‐SMT SENCos. 相似文献
