Oded Bar-Or　Linda Houtkooper　Susan Barr　Anita Rivera-Brown　Michael Bergeron　Tom Rowland　Ruth Carey　Suzanne Steen　Priscilla Clarkson 《体育科学》2001,21(5):89-93

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

Data integrity boards: Institutional innovation and congressional oversight     

Priscilla M. Regan 《Government Information Quarterly》1993,10(4)

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

How we done it good: Research through design as a legitimate methodology for librarianship     

Rachel Ivy Clarke 《Library & information science research》2018,40(3-4):255-261

“How we done it good” publications—a genre concerning project-based approaches that describe how (and sometimes why) something was done—are often rebuked in the library research community for lacking traditional scientific validity, reliability, and generalizability. While scientific methodologies may be a common approach to research and inquiry, they are not the only methodological paradigms. This research posits that the how we done it good paradigm in librarianship reflects a valid and legitimate approach to research. By drawing on the concept of research through design, this study shows how these how we done it good projects reflect design methodologies which draw rigor from process, invention, relevance, and extensibility rather than replicability, generalizability, and predictability. Although these projects implicitly reflect research through design, the methodology is not yet explicitly harnessed in librarianship. More support for these types of projects can be achieved by making the legitimate design framework more explicit and increasing support from publication venues.  相似文献   

How We Used to Build the Future: 30 Years of Collection Development Trends     

Betsy Appleton  Justin Clarke  Laurie Kaplan  Dani Roach  Rebecca Kemp Goldfinger 《期刊图书馆员》2016,70(1-4):198-203

This session highlighted trends in continuing resource collections and collection management throughout the 30-year period from 1985 through 2015. Electronic resources became available in the 1990s and grew in prevalence from the 2000s through the present, changing the make-up of library collections and also how libraries measure collections and collection usage. Two librarians and two vendors shared their perspectives on these changes in collection development, describing how library collections now contain a combination of older formats and older ways of collecting data, and new, electronic content and automated ways of collecting and disseminating data about collections.  相似文献   

Classroom dialogue and science achievement     

John Clarke 《Research in Science Education》1988,18(1):83-94

Conclusion This study indicates the responsibility that rests with the teacher in an activity-oriented classroom as far as providing the structural support necessary for effective learning (Note 4). The teacher is acting as a “surrogate textbook”. Using their own organization of knowledge-albiet wrong or incomplete-teachers provide the structure that is lacking. As the results indicate, some teachers can do this better than others. A challenge for teachers and teacher educators is to devise ways to improving the structure and sequencing of classroom dialogue. The TSA Technique could help here in two ways. It allows a sophisticated analysis of dialogue, indicating specific areas of weakness which could then be remedied by appropriate training. A similar approach has been used successfully with text material to rewrite and restructure deficient segments (Clarke; 1973). It could also be used to produce ideal “templates” of various models of teaching (e.g. Brady; 1985) for use as a guide for lesson planning.  相似文献   

Exploring the relationship between early childhood and elementary grade-level overlap and early childhood teacher output     

R. Clarke Fowler 《Journal of Early Childhood Teacher Education》2017,38(2):150-163

This study explores the relationship between grade-level overlap between elementary education (ELED) and early childhood education (ECED) licenses and ECED teacher output. Analysis of Title 2 data indicates that ECED/ELED overlap is extensive, as evidenced by the number of states with grade-level overlaps of 5 (n = 2), 4 (n = 24), 3 (n = 10), and 2 years (n = 7). In the 47 states with both types of credentials, ELED licensees may teach preschool in two states, kindergarten in 30, first grade in 41, second grade in 42, and third grade in 43. The percentage of ECED (relative to ELED) teacher licensure program completers is low in states where elementary licenses begin in preschool (5%), kindergarten (14%), and Grade 1 (23%), but higher in states where elementary licenses begin in Grades 2 (45%), 3 (44%), and 4 (70%).  相似文献
