A utility model for teaching load decisions in academic departments     

William F. Massy  Robert Zemsky 《Economics of Education Review》1997,16(4):349-365

The authors model the class size and teaching load decisions of academic departments in terms of a departmental utility function. Utility is postulated to be asymmetric around class size and teaching load norms, and variables for curricular structure, disciplinary domain, and institutional type are taken into account. Maximization of the utility function produces decision rules for the number of sections to be offered for each course, and hence the faculty's overall teaching load. A nonlinear estimator is developed for the decision rules' parameters and applied to data from four liberal arts colleges and two research universities. Results are consistent with theories about faculty discretionary time and with expectations about the effects of curricular structure on class size. The paper concludes with a discussion about the effects of enrollment uncertainty on faculty load decisions.  相似文献

Diarrhea Management Training in Early Childhood Settings     

Scott D. Winnail  Lynn M. Artz  Brian F. Geiger  Cynthia J. Petri  Rebecca Bailey  J. W. Mason 《Early Childhood Education Journal》2001,28(4):231-236

This study addresses the health of young children and how to safely and effectively care for children with diarrhea in the home and in early child care settings. A baseline survey showed the prevalence of oral rehydration solution (ORS) usage at last diarrhea bout to be low. An educational workshop was developed to train parents and child care professionals on how to properly manage young children with diarrhea and reduce the risk of diarrhea spread at home and in early childhood settings. Specific intervention activities are discussed and program activities, including specially designed materials for mixing homemade ORS are described. A comparison of pre- and postintervention data indicates substantial gains in knowledge among both urban and rural populations. Implications of research findings are discussed along with suggestions for future research.  相似文献   

Adaptive progressive download based on the MPEG-4 file format     

Färber Nikolaus  Döhla Stefan  Issing Jochen 《浙江大学学报(A卷英文版)》2006,7(1):106-111

In this paper we describe how progressive download and adaptive streaming can be combined into a simple and efficient streaming framework. Based on the MPEG-4 file format (MP4) we use HTTP for transport and argue that these two components are sufficient for specifying an open streaming architecture. The client selects appropriate chunks from the MP4 file to be transferred based on (1) the header information (i.e. the “moov” box) in the first part of the file and (2) his observation of network throughput. The framework is completely client driven which allows for better server scalability and reduces signalling overhead. We discuss architecture and implementation issues such as complexity, interoperability and scalability and compare to 3GPP PSS Rel-6 adaptive streaming when appropriate. Measurements from a simple MP4/HTTP streaming client are presented showing that appropriate chunks are selected such that increased reliability is achieved.  相似文献   

Should We Be Testing Civics? Examining the Implications of the Civic Education Initiative     

Kristina F. Brezicha  Dana L. Mitra 《Peabody Journal of Education》2019,94(1):63-77

Given the importance of developing civically engaged and knowledgeable citizens, many have sought to improve the quality of students’ civic education experiences. This article examines one particular effort spearheaded by the Joe Foss Institute, the Civic Education Initiative (CEI). Since the CEI was announced, 18 states have passed legislation that includes a civics test component embedded in the CEI. This conceptual article examines the CEI against research-based practices for teaching civics. It then introduces the policy design framework as a tool for analyzing civic policies like CEI. This political science theory recognizes that policies themselves send important signals that have implications for students’ civic development. We utilize the policy design framework to analyze CEI and, in particular, how CEI is likely to shape students’ civic and political engagement. We conclude with a proposal for future research on civic education using the policy design framework.  相似文献

An analysis of assignment completion and accuracy across time under fixed, variable, and extended token exchange periods in a classroom token economy     

T. F. Mc Laughlin  J. E. Malaby 《Contemporary educational psychology》1976,1(4):346-355

This research investigated the effects of employing fixed, variable, and extended token exchange periods for backups on the completion and quality of daily assignments of a total fifth- and sixth-grade class. The results indicated a higher percentage of assignments was completed when the number of days between point exchanges was variable, and that performance was maintained when the number of school days between point exchanges was gradually increased. The overall accuracy on assignments was high, but varying, and did not appear to be under the systematic control of the experimental procedures. Data for all pupils indicated that there were individual differences as to the effects of the various token (point) exchange procedures. Pupils with inconsistent assignment completion during Fixed Exchange Conditions (Fixed Period (FP-I, -II, -III) increased their assignment completion during the Variable Token Exchange Procedures (Variable Period (VP)-I, -II, -III). Thus, the variable sequencing of the number of days should be an important consideration in any effort to maintain the positive effects of token-reinforcement systems within classroom settings.  相似文献
