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

Current findings from research on structured abstracts.   总被引:5,自引:0,他引:5  
BACKGROUND: Structured abstracts were introduced into medical research journals in the mid 1980s. Since then they have been widely used in this and other contexts. AIM: The aim of this paper is to summarize the main findings from research on structured abstracts and to discuss the limitations of some aspects of this research. METHOD: A narrative literature review of all of the relevant papers known to the author was conducted. RESULTS: Structured abstracts are typically longer than traditional ones, but they are also judged to be more informative and accessible. Authors and readers also judge them to be more useful than traditional abstracts. However, not all studies use "real-life" published examples from different authors in their work, and more work needs to be done in some cases. CONCLUSIONS: The findings generally support the notion that structured abstracts can be profitably introduced into research journals. Some arguments for this, however, have more research support than others.  相似文献

The Cross-Language Evaluation Forum has encouraged research in text retrieval methods for numerous European languages and has developed durable test suites that allow language-specific techniques to be investigated and compared. The labor associated with crafting a retrieval system that takes advantage of sophisticated linguistic methods is daunting. We examine whether language-neutral methods can achieve accuracy comparable to language-specific methods with less concomitant software complexity. Using the CLEF 2002 test set we demonstrate empirically how overlapping character n-gram tokenization can provide retrieval accuracy that rivals the best current language-specific approaches for European languages. We show that n = 4 is a good choice for those languages, and document the increased storage and time requirements of the technique. We report on the benefits of and challenges posed by n-grams, and explain peculiarities attendant to bilingual retrieval. Our findings demonstrate clearly that accuracy using n-gram indexing rivals or exceeds accuracy using unnormalized words, for both monolingual and bilingual retrieval.  相似文献

Communication researchers increasingly have a primed and attentive audience in private foundations. Yet most foundations are quite dissimilar to the types of organizations that we as communication scholars know and understand. Here we discuss private foundation funding for applied communication research, including how funding priorities are set, and how potential grantees may position themselves for foundation funds. In doing so, we focus on five norms that characterize American private foundations and their program staff: (1) social betterment, (2) organizational interdependency, (3) personal commitment, (4) future orientation, and (5) external generalizability. How well you and your proposal match up with these norms will affect your success with private foundations.  相似文献

This study examined the means of and correlations between perceptions of willingness to communicate, communication apprehension, and communication competence of college students in the United States and Australia. Comparisons indicated a high degree of similarity in the relationships between communication orientations in the two cultures but substantial differences between the cultures in terms of mean scores on willingness to communicate and self‐perceived communication competence. Results of the study suggest similarities between people of two different cultures on one communication orientation do not necessarily indicate similarities on other communication orientations. However, relationships between orientations may have some generalizability across cultures.  相似文献
