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

ABSTRACT The current study examined the case of religious students who opted to study in a secular teacher-training college despite the fact that there are religious colleges that would have suited their needs. This phenomenon is unusual because the education system in Israel is segregated and each educational sector has its own teacher-training colleges. Findings of this qualitative study indicate that the majority of participants did not wish to depart from the religious framework, but rather sought to forge reciprocal relations with the secular society and carve a space for themselves where they could express their identity, which does not entirely conform to the demands of the religious society. These findings highlight an interesting dynamic that developing between students from a minority group and the mainstream secular society in Israel that promotes multiculturalism. An academic campus that adopts a multicultural approach is a safe space for minority students, whose sectorial framework does not fully provide for all their needs. 相似文献

Negation recognition in medical narrative reports 总被引：1，自引：0，他引：1
Substantial medical data, such as discharge summaries and operative reports are stored in electronic textual form. Databases
containing free-text clinical narratives reports often need to be retrieved to find relevant information for clinical and
research purposes. The context of negation, a negative finding, is of special importance, since many of the most frequently
described findings are such. When searching free-text narratives for patients with a certain medical condition, if negation
is not taken into account, many of the documents retrieved will be irrelevant. Hence, negation is a major source of poor precision
in medical information retrieval systems. Previous research has shown that negated findings may be difficult to identify if
the words implying negations (negation signals) are more than a few words away from them. We present a new pattern learning
method for automatic identification of negative context in clinical narratives reports. We compare the new algorithm to previous
methods proposed for the same task, and show its advantages: accuracy improvement compared to other machine learning methods,
and much faster than manual knowledge engineering techniques with matching accuracy. The new algorithm can be applied also
to further context identification and information extraction tasks.

Do academic journals favor authors who share their institutional affiliation? To answer this question we examine citation counts, as a proxy for paper quality, for articles published in four leading international relations journals during the years 2000–2015. We compare citation counts for articles written by “in-group members” (authors affiliated with the journal’s publishing institution) versus “out-group members” (authors not affiliated with that institution). Articles written by in-group authors received 18% to 49% fewer Web of Science citations when published in their home journal (International Security or World Politics) vs. an unaffiliated journal, compared to out-group authors. These results are mainly driven by authors who received their PhDs from Harvard or MIT. The findings show evidence of a bias within some journals towards publishing papers by faculty from their home institution, at the expense of paper quality. 相似文献

Performance at the Defense Language Institute was examined through the prism of human performance technology and the strategic impact model. This examination revealed performance deficiencies in the administrative realm that required mainly a noninstructional intervention. A systematic analysis showed that digitizing administrative procedures could substantially decrease operational costs, enhance procedural transparency, and increase employees' satisfaction. 相似文献

This paper presents and examines the first school change program focusing on violence and caring based on self-determination theory (Deci &; Ryan, 2012). The program aimed at promoting teachers' capacity to cope with violence and enhance caring without becoming more controlling. Comparisons of the effects of a 22-month-long program in three intervention schools and three control schools indicated that the program (a) reduced violent student behavior and controlling teacher behavior and (b) enhanced caring student behavior and active teacher response to violence. The results suggest that exposure to self-determination theory (SDT) concepts may promote a firm, yet non-controlling, teacher response to violence. More generally, the results highlight the potential for incorporating SDT ideas in violence reduction programs. 相似文献

In this essay, Oded Zipory assigns a different meaning to presentism in education: one that signifies respect for the present, especially for the actual student in his here‐and‐now. Zipory suggests that the key component of such a presentist pedagogy is interest and argues that focusing on children's current and possible interests instead of, or at least in addition to, working toward their expected future achievement is both respectful of children as meaning‐makers and promising in regard to their autonomy. First, he lays out principles for a presentist pedagogy of interest. Following Harry Frankfurt's work on the concept of care, Zipory suggests that schools should pay attention to the fact that students care about various things in addition to focusing on children's required knowledge and desired behavior. He then shows that being interested in something is a particular form of caring about it, and that this form is closely connected to education and learning. After showing the importance of interests to education, Zipory presents the challenges to incorporating them into a curriculum, and, drawing on P. S. Wilson's work, suggests strategies for coping with these challenges. He concludes by addressing the temporal tension embedded in the word “interest” itself and suggests that, in order to distance education from instrumentalization and commodification, a present‐oriented meaning of interest should be adopted. 相似文献

We propose that children's reasoning about others' visual perspectives is guided by simple heuristics based on a perceiver's line of sight and salient features of the object met by that line. In 3 experiments employing a 2-perceiver analogy task, children aged 3-6 were generally better able to reproduce a perceiver's perspective if a visual cue in the perceiver's line of sight sufficed to distinguish it from alternatives. Children had greater difficulty when the task hinged on attending to configural cues. Availability of distinctive cues affixed on the objects' sides facilitated solution of the symmetrical orientations. These and several other related findings reported in the literature are traced to children's reliance on heuristics of reasoning. 相似文献

The War-Time Communications Project (WTCP), conducted during the Second World War, was a major event in the evolution of communication science. A prominent place in it was occupied by Professor Harold D. Lasswell's study on Hitler's speeches, in which the ‘speech model’ was examined in reference to its vocal components and non-verbal communication elements – in terms of ‘how spoken’, rather than of ‘what said’, with an emphasis on audience feedback. This approach formed part of Lasswell's innovative idea: quantification of the word domain. The study was of one of a series of content analysis research works undertaken at the Library of Congress at that time, part of an attempt at ‘keeping an eye’ on world peace. The present article, the first exposition of Lasswell's opus, highlights one of his central concepts – linguistic transformation. 相似文献
