Reducing Alcohol Use in First‐Year University Students: Evaluation of a Web‐Based Personalized Feedback Program     

Diana M. Doumas  Lorna L. Andersen 《Journal of College Counseling》2009,12(1):18-32

The efficacy of a Web‐based personalized feedback program—electronic CHECKUP TO GO (e‐CHUG), aimed at reducing heavy drinking in 1st‐year university students—is evaluated. Results indicated that high‐risk students in the e‐CHUG group reported significantly greater reductions in weekly drinking quantity frequency of drinking to intoxication, and occurrence of alcohol‐related problems. Recommendations for integrating Web‐based alcohol programs into a comprehensive prevention program are discussed.  相似文献

Governance Initiatives Creating a Demand-Driven E-Commerce Approach: The Case of Denmark     

Kim Viborg Andersen  Niels Bj  rn-Andersen  Jason Dedrick 《The Information Society》2003,19(1):95-105

The Danish e-commerce strategy is a highly ambitious effort to become the world's leading IT nation. Instead of a production-led approach aimed at stimulating domestic hardware and software production, Denmark has pursued a demand-oriented approach focused on promoting the widespread adoption of e-commerce in the Danish society. The Danish government has developed a number of e-commerce initiatives via public-private sector partnerships--an approach we refer to as "governance." So far, it appears that Denmark has been successful in promoting business-to-business (B2B) e-commerce, with a number of Danish companies being global leaders in the use of B2B applications. On the other hand, Denmark has had less success in achieving widespread use of business-to-consumer (B2C) e-commerce. This article analyzes the Danish national environment for e-commerce, discusses four sets of governance initiatives aimed at the development of e-commerce, and analyzes the reasons for its success in B2B and relative failure in B2C adoption.  相似文献   

A Systematic Literature Review of Changes in Roles/Skills in Component Content Management Environments and Implications for Education     

Tatiana Batova  Rebekka Andersen 《Technical Communication Quarterly》2017,26(2):173-200

Component content management (CCM) enables organizations to create, manage, and deliver content as small components rather than entire documents. As CCM methodologies, processes, and technologies are increasingly adopted, CCM is reshaping technical communication (TC), the roles of technical communicators, and the skills they need for career success. This article reviews scholarly and trade publications that describe changes in roles and needed skills in CCM environments and identifies implications of these changes for TC education.  相似文献   

Designing,evaluating, and reacting to a secondary science methods class     

William J. Boone  Hans O. Andersen 《Journal of Science Teacher Education》1994,5(1):15-22

Most science educators spend much of their time planning and teaching science methods classes yet there is very little dialogue among science educators concerning what ought to be taught. This study involved a small sample. Readers should think of it as a model for conducting similar self-studies. The instructor of this course has been teaching it since 1966, and each year, he has revised 10–20% of it. These data show that some, but not all, of the revisions have resulted in improvement. This analysis illustrates how helpful the perceptions of methods students can be for initiating and continuing a dialogue among educators regarding the structure of methods courses. Although the question of “What ought to be taught?” has been clarified to a degree, it has and always will remain.  相似文献   

An Empirical Investigation of Impact Moderation in Test Construction     

Martha L. Stocking  Ida Lawrence  Miriam Feigenbaum  Thomas Jirele  Charles Lewis  Thomas Van  Essen 《Journal of Educational Measurement》2002,39(3):235-252

This investigation constructed four different kinds of test sections using three methods of test assembly that incorporate the goals of simultaneous moderation of three kinds of impact-gender impact, African-American impact, and Hispanic- American impact. The test sections were administered undetectably to random samples from the appropriate population. The results were evaluated by comparison of the characteristics of moderated sections with those of parallel operational sections. Almost all methods of test assembly produced either moderation of impact in the appropriate direction or no change in impact. Taking impact into account in test assembly tended to lower reliability slightly, raise concurrent validity slightly, and maintain the construct measured by the parallel operational section. It also reduced the relative efficiency for test takers in the middle score range while increasing efficiency for those with more extreme scores.  相似文献   

A Comparison of Bias Reduction Methods: Clustering versus Propensity Score Subclassification and Weighting     

Ida D'Attoma  Furio Camillo  M. H. Clark 《Journal of Experimental Education》2019,87(1):33-54

Propensity score (PS) adjustments have become popular methods used to improve estimates of treatment effects in quasi-experiments. Although researchers continue to develop PS methods, other procedures can also be effective in reducing selection bias. One of these uses clustering to create balanced groups. However, the success of this new method depends on its efficacy compared to that of the existing methods. Therefore, this comparative study used experimental and nonexperimental data to examine bias reduction, case retention, and covariate balance in the clustering method, PS subclassification, and PS weighting. In general, results suggest that the cluster-based methods reduced at least as much bias as the PS methods. Under certain conditions, the PS methods reduced more bias than the cluster-based method, and under other conditions the cluster-based methods were more advantageous. Although all methods were equally effective in retaining cases and balancing covariates, other data-specific conditions may likely favor the use of a cluster-based approach.  相似文献   

Using Group Viewing of Television to Teach Preschool Children Social Skills     

Ida Eva Zielinska  Bette Chambers 《Learning, Media and Technology》1995,21(2):85-99

This quasi‐experimental field study assessed whether group viewing of television in a day‐care setting can be used to encourage prosocial behavior in young children. Drawing from social learning theory and cognitive‐developmental stage theory, four short‐ term programs were designed and tested. Children (aged 3‐5 years) from eight day‐care centers in Montreal (n = 150) were part of the study. Intact groups (two settings randomly assigned to condition) participated in 8 days of intervention consisting of group viewing of video‐taped segments of Sesame Street, followed by participation in activities. The programs were evaluated using a 2 X 2 X 2 factorial pretest—post‐test design with video‐type (prosocial, cognitive), activity‐type (cooperative, individualistic), and gender as the three factors. Measures included free‐play observations, a perspective‐taking ability test, and two qualitative measures describing the context. Analysis of covariance (pretest and age combined as covariates) revealed a significant main effect for video‐type on prosocial behavior, and a significant interaction between video‐type and activity‐type on antisocial behavior. Results suggest that prosocial modelling using television can encourage prosocial behavior in the day‐care setting. A group‐viewing context, with or without post‐viewing enactive prosocial training, may enhance prosocial modeling effects.  相似文献

In search of a useful theory of the productive potential of intellectual property rights   总被引：1，自引：0，他引：1  

Birgitte Andersen  Sue Konzelmann 《Research Policy》2008,37(1):12-28

Mainstream theory, which has informed the belief systems regarding the operation as well as the predicted social and economic effects of IPR systems, cannot explain why the IPR system generates different performance results and varying potential for growth across the firms, sectors and nations participating in the IPR system. This paper sketches a theory of the ‘productive potential of intellectual property rights’ which is able to do just that. Focusing on the ‘rules of the game’ embedded in the institutional IPR environment and the ‘play of the game’ within the alternative institutions of IPR governance, the paper emphasizes the importance of the nature or quality of the relationships among IPR stakeholders and the contribution of such relationships to the processes of financial and non-financial value creation and distribution from IPRs. The central role of cooperation, asymmetric relationships, and the effective resolution of conflicting interests amongst stakeholders is addressed. It is suggested that the proposed framework provides a better starting point for the design of IPR policy and management.  相似文献
