P L Newcomer  E M Barenbaum 《Journal of learning disabilities》1991,24(10):578-593

This article reviews the literature pertaining to the written composing ability of students with learning disabilities that was published primarily in the decade from 1980 to 1990. The papers included are either reports of research or discussions of instructional procedures that are based on research. The topics addressed include story composition, expository writing, training/intervention research, and rationales/procedures for instruction.  相似文献

体育观赏活动的经济学分析   总被引：6，自引：1，他引：5  

刘卫  杨刚 《体育学刊》2003,10(2):16-19

用微观经济学理论探讨体育观赏市场产品的需求与供给特征，为合理配置市场资源提供一定的理论依据。研究结果显示：（1）体育观赏活动在经济中表现为体育观赏市场及体育观赏派生产品市场两种形态；（2）消费对体育观赏市场产品的需求原则是第i个人看k场比赛用－第i个人看k场比赛的非资金代价－现场观看第k场比赛的门票费－第i个人看k场比赛支付交通费＞0，因其产品的不可重复性，结果的不确定性及悬念性，需求不存在一般意义上的边际效用递减，运动员作为体育观赏市场产品的载体，其竞技表演质量是影响产品供给的重要因素，其酌量性固定成本的投入比重也较大；（3）体育观赏市场的资源配置要达到帕累托最佳状态，政府政策的合理介入是必要的。  相似文献   

经济订货量基本模型的一种扩展及其数学推导     

伍刚  熊于宁 《成都师专学报》2006,25(4):83-84

目前使用的经济订货量基本模型的缺陷是未考虑商业折扣。据此，本文在考虑有商业折扣的情况下对经济订货量的基本模型进行了扩展，并推导出了具有较好实用性的简明结论。  相似文献   

PUBLIC AND ELITE ATTITUDES TO ENVIRONMENTAL ISSUES   总被引：1，自引：0，他引：1  

Worcester  Robert M. 《Int. Journal of Public Opinion Research》1993,5(4):315-334

This paper puts the environment into perspective. Politiciansand commentators see the environment as yesterday's issue, forgettingthat the core of environmental activists is still double thelevel of just five years ago. International comparisons stretchingfrom Poland to New Zealand are made, examining the public'senvironmental behavior, attitudes and values. Using Great Britainas a case study, detailed comparisons are made between the attitudesof the general public with journalists, the financial community,captains of industry, and Members of Parliament and the latterthen compared with Members of the European Parliament. The publicis demanding action by companies and by governments on environmentalissues and has little faith in either to take corrective action.  相似文献

Morphological proportionality in elite age group North American divers.     

D Sovak  M R Hawes  K Plant 《Journal of sports sciences》1992,10(5):451-465

The purpose of this investigation was to describe the morphological parameters that characterize elite age group divers. Comparisons are made to normative age group data from the Coquitlam Growth Study and the constancy of important characteristics from age group to age group is examined. Data were collected on 27 male and 28 female elite divers who participated in the 1990 North American Age Group Diving Championships. Body build, body composition and skinfold corrected diameters were determined from 36 anthropometric parameters and analysed by ANOVA, t-test and Phantom z-scores procedures. All age groups except the 14- to 15-year-old males were significantly (P < or = 0.05) shorter than their norms but recorded higher androgyny index values. The estimated relative muscle mass increased significantly (P < or = 0.05) with age for males at all ages (40.8-46.3%). The 16- to 18-year-old females had a significantly (P < or = 0.05) larger relative muscle component compared to the younger age groups (40.1-38.4%). When normalized for height, active tissue development of the extremities was comparable between the sexes except in the forearm. The results indicate that at all age levels short stature is an important characteristic for divers. Analysis of regional active tissue development provides further insight into sport-specific prerequisites for success at elite levels.  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
