In Korean information retrieval, compound nouns play an important role in improving precision in search experiments. There are two major approaches to compound noun indexing in Korean: statistical and linguistic. Each method, however, has its own shortcomings, such as limitations when indexing diverse types of compound nouns, over-generation of compound nouns, and data sparseness in training. In this paper, we propose a corpus-based learning method, which can index diverse types of compound nouns using rules automatically extracted from a large corpus. The automatic learning method is more portable and requires less human effort, although it exhibits a performance level similar to the manual-linguistic approach. We also present a new filtering method to solve the problems of compound noun over-generation and data sparseness. 相似文献

The goal of this study was to define the construct and establish the validity of disciplinary literacy, which has recently gained attention from the implementation of the Common Core State Standards (National Governors Association Center for Best Practices & Council of Chief State School Officers in Common Core State Standards for English language arts & literacy in history/social studies, science, and technical subjects [PDF]. Authors, Washington, DC, 2010). After defining disciplinary literacy in the four core disciplines of English language arts, science, history and social studies, and mathematics, scales were developed and administered to a snowball sample of professionals nationwide, with 857 respondents. The data showed evidence of disciplinary literacy as a multidimensional construct with three related factors: source literacy, analytic literacy, and expressive literacy. Based on EFA and CFA results, we can conclude that there are at least three types of literacy in operation among the four core disciplines. The three factors of literacy varied significantly by the four core disciplines of English/language arts (ELA), science, history and social studies, and mathematics, supporting the notion that each discipline uses literacy uniquely. This is the first study of its kind to attempt to define, quantify, and validate the construct of disciplinary literacy. 相似文献

This study aims to explore how media use for health information and interpersonal health communication interact in the context of healthy lifestyle behaviors. This study hypothesizes that media use for health information and interpersonal health communication will serve as substitutes for one another. To test this hypothesis, this study uses a nationally representative survey of 2,107 civilian, noninstitutionalized adults in the United States. The results show that the associations between television use and Internet use and healthy lifestyle behaviors are enhanced among those who talk about health issues with their family and friends less frequently, which supports the substitution model. The implications that these findings have for future research are discussed. 相似文献

Intellectual Disability and Developmental Risk: Promoting Intervention to Improve Child and Family Well‐Being 下载免费PDF全文

Initial intervention processes for children with intellectual disabilities (IDs) largely focused on direct efforts to impact core cognitive and academic deficits associated with the diagnosis. Recent research on risk processes in families of children with ID, however, has influenced new developmental system approaches to early intervention. Recent risk and resilience processes are reviewed that connect stress, family process, and the high rates of behavioral problems in children with ID that have substantial influence on child and family outcomes. These models are linked to emerging evidence‐based intervention processes that focus on strategic parent skill training and mindfulness interventions that reduce parental stress and create indirect benefits for children's behavioral competencies. A family‐focused developmental systems approach (M. J. Guralnick, 2011) is emphasized. 相似文献

This study theorized and validated a model of knowledge sharing continuance in a special type of online community, the online question answering (Q&A) community, in which knowledge exchange is reflected mainly by asking and answering specific questions. We created a model that integrated knowledge sharing factors and knowledge self-efficacy into the expectation confirmation theory. The hypotheses derived from this model were empirically validated using an online survey conducted among users of a famous online Q&A community in China, “Yahoo! Answers China”. The results suggested that users’ intention to continue sharing knowledge (i.e., answering questions) was directly influenced by users’ ex-post feelings as consisting of two dimensions: satisfaction, and knowledge self-efficacy. Based on the obtained results, we also found that knowledge self-efficacy and confirmation mediated the relationship between benefits and satisfaction. 相似文献

The purpose of this study was to examine what, if anything, caregivers and teachers of 3- to 5-year-old children from the U.S. (n = 412), China (n = 244), Taiwan (n = 222), Korea (n = 574), and Turkey (n = 214), had in common in terms of self-reported beliefs and self-reported practices related to the National Association for the Education of Young Children's (NAEYC) policy statement for developmentally appropriate practices (DAP). DAP is widely endorsed by early childhood education and care professionals in the U.S. and is assumed to have far reaching impact on curricular beliefs and practices throughout the world. Pearson correlations and one-way ANOVA were used to compare overall mean scores for beliefs measured by the Teachers Beliefs Scale (TBS) to those of practices measured by the Instructional Activities Scale (IAS) [Charlesworth, R., Hart, C. H., Burts, D. C., & Hernandez, S. (1991). Kindergarten teachers’ beliefs and practices. Early Child Development and Care, 70, 17–35]. Item-by-item analyses were conducted using factor analysis and χ2 analyses within and across countries. Similarities emerged related to, in particular, those beliefs and teaching practices associated with integrating across the curriculum, promoting social/emotional development, providing concrete/hands-on materials, and allowing play/choice in the curriculum. 相似文献

We examined whether individual interest, as an affective motivational variable, could predict academic self-regulation and achievement, above and beyond what academic self-efficacy predicted. We tested the relationships between academic self-efficacy, individual interest, grade goals, self-regulation, and achievement of Korean middle school students (N = 500) in four different subject areas. Consistent with previous findings, self-efficacy predicted achievement both directly and indirectly via grade goals. Self-efficacy also predicted self-regulation, but only when grade goals mediated the relationship. Supporting our hypothesis, individual interest functioned as a correlated yet independent and direct predictor of self-regulation. It also predicted achievement, but only when self-regulation mediated the relationship. We thus suggest that academic self-regulation could be encouraged through the promotion of two distinct motivational sources, academic self-efficacy and individual interest. We further suggest that the pathways linking individual interest to academic self-regulation and achievement may differ from those linking academic self-efficacy to the same variables. 相似文献
