Behavior modification procedures are described for establishing compliant behavior in elective mutes. The results are discussed for three children to whom the procedure was applied. The length of the training period was two weeks for the first child, twelve days for the second, and six weeks for the third. Two of the three subjects generalized responsive and spontaneous language from the experimental to everyday settings. 相似文献

The analysis of longitudinal data in education is becoming more prevalent given the nature of testing systems constructed for No Child Left Behind Act (NCLB). However, constructing the longitudinal data files remains a significant challenge. Students move into new schools, but in many cases the unique identifiers (ID) that should remain constant for each student change. As a result, different students frequently share the same ID, and merging records for an ID that is erroneously assigned to different students clearly becomes problematic. In small data sets, quality assurance of the merge can proceed through human reviews of the data to ensure all merged records are properly joined. However, in data sets with hundreds of thousands of cases, quality assurance via human review is impossible. While the record linkage literature has many applications in other disciplines, the educational measurement literature lacks details of formal protocols that can be used for quality assurance procedures for longitudinal data files. This article presents an empirical quality assurance procedure that may be used to verify the integrity of the merges performed for longitudinal analysis. We also discuss possible extensions that would permit merges to occur even when unique identifiers are not available. 相似文献

This paper examines several key debates in the literature onthe effects of economic performance on political support, usingthe Continuous Monitoring Survey of the 1984 CPS American nationalelection study. Box-Jenkins time-series analyses show that theelectorate operates in terms of a reward-punishment model whichis asymmetrical and sociotropic in its effects. In the modelsdeveloped party identification and economic evaluations Grangercausepresidential approval, the effects of the former being strongerthan those of the latter. Partisanship and economic evaluationsform two independent streams of influence on presidential approval,casting doubt on some revisionist interpretations in the votingliterature, i.e., that party identification is simply a runningtally of voters' judgments about party performance on economicand other issues. In addition, the results suggest that popularityfunctions which omit party identification are theoreticallymisspecified. 相似文献
