儿童青少年运动员的营养需要

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。

Population differences in constructive memory

An experiment was conducted to evaluate constructive memory in fourth-grade low-SES black and middle-SES white children. The children were read nine short passages; each passage was composed of two premise statements and a filler sentence. The children were tested by a recognition procedure. Thirty-six test sentences were presented randomly. Four sentences were associated with each passage (true premise, false premise, true inference, and false inference). Subjects were asked to make yes/no recognition decisions based on whether the test sentence was identical to a sentence presented at study. Middle-SES white children made few errors, except to true inference test sentences. This pattern of performance is consistent with the constructive view of memory. Low-SES black children also had a high error rate to true inference items. However, this outcome may not reflect constructive memory because they also had a high error rate to some of the other types of test sentences.

From national policy-making to global edu-business: Swedish edu-preneurs on the move

This study explores the movements of some Swedish former education policy-makers that are currently active as commercial edu-business actors with the ambition to expand in the Global Education Industry (GEI). The aim is to map and analyze how a selection of Swedish edu-preneurs affiliated with a particular Swedish school chain enter the GEI and thereby market both their commercialized services and the policy ideas about so-called free schools, in its Swedish version. The study shows how these edu-preneurs move from the domestic to global arenas and how their business and policy advocacy activities are framed and represented. Mobilization and public exposure of previous and present policy advocacy networks are important assets for these edu-preneurs as they navigate the GEI. The study illustrates how these actors make use of particular forms of knowledge, from department ministerial work and party politics, which blends with work in public relations and various edu-businesses, pointing to the interrelatedness of politics, policy, business, power, and ideology. The paper concludes by raising issues in need of further exploration and debate, pertaining to our understanding of education policy-making and, ultimately, democracy.
