Requests for monographs generated within an interlibrary loan network are analyzed for half-life statistics. It is suggested that demand represents use of the literature more completely than satisfied requests or circulation statistics. Demand in this study is characterized as either regional demand or statewide demand and is related to the level of the network where final processing of the request occurs. A negative exponential distribution is found to adequately characterize both levels of demand as a function of publication date for four subject categories. Corrected demand data is obtained by removing the growth rate of most of the available literature represented by American book publisher output. Based on over 10,000 interlibrary loan requests, negative exponential distributions describe the raw data as well as the corrected data. A shorter half-life was found for regional library demand (10.47 yr) than that found for statewide library demand (15.75 yr). Applying the correction factor to reflect the growth rate of the available literature tends to increase the half-life when compared to the raw data, and changes the ordering of subject classes with respect to ascending half-lives. 相似文献

Domestic violence against women is a significant social and public health problem that requires a varied social service response for abused women and their children. Increasingly, this service response includes online sources and resources. Using content analysis methods, we examined the Canadian provincial E-Government response to providing information to women exposed to domestic violence. Our overarching question was “if an abused woman went to her province’s government website for information and help and used common search strategies, what would she find?” 相似文献

This study investigated teachers’ experiences of closeness during interactions with the group of children in child care. Structured interviews were conducted with 24 female teachers who were teaching children between the ages of three and five (mean age = 3.9) regarding their perceptions of closeness with the group of children in the class. Qualitative analyses of the interviews revealed a group solidarity domain of teacher–group relationships composed of three dimensions which comprise emotional solidarity, consensual solidarity, and functional solidarity, with emotional solidarity most dominant in the teachers’ perceptions. This group solidarity domain was interpreted as being consistent with qualities found in Grusec and Davidov’s group participation domain. The findings that, teachers’ closeness with the group of children in the class were dominated by the emotional dimension is similar to previous research results which report the predominance of personal and intimate interactions in relational closeness between teachers and individual children. Teachers described intentional strategies for managing close group relationships that made use of interactional histories between the teachers and children in the class. These discoveries provide a new perspective on teacher closeness with groups, an area of research not often investigated. It also provides insights into the importance teachers place on connecting emotionally with children when they are with the collective group in the classroom. 相似文献

The primary goal of the Words Work (WW) early literacy initiative was to prepare diverse students to become successful learners in school. Four groups of students were followed over 6 years: students from traditional Head Start (HS) centers, students from augmented HS centers (WW students), students eligible for HS but not enrolled (waitlist or WL), and a random sample of non-Head Start students (NHS). Students received school readiness instruction at approximately 4 years of age, and their performance on standardized tests was followed from 1st grade through 5th grade. WW students significantly outscored HS, WL, and NHS students of similar backgrounds in reading and outscored WL and NHS students in mathematics on 2nd-grade standardized assessments. In addition, WW students were able to maintain their lead through 5th grade in both reading and mathematics. Based on these results, WW is an effective HS enhancement for minimizing the achievement gap often observed between students who may be at risk for academic difficulty and students who are at low risk. 相似文献

The purpose of this study was to explore the extent to which distance learning (distance learning vs. traditional) may influence undergraduate education majors’ emerging constructivist perspective. Elementary education majors at 2 universities (N = 102) volunteered to complete questionnaires. The 3 independent variables were traditional vs. distance learning, whether or not ever enrolled in distance learning, and instructor difference. The 3 dependent variables were concerned with what the instructor provided; what the instructor demonstrated; and what students believed they learned. A Multiple Analysis of Variance (Manova) compared the 3 independent variables across the 3 dependent variables and indicated that students in traditional classrooms rated what the instructor provided, what the instructor demonstrated, and what students believed they learned significantly greater than students in distance learning classrooms. An interpretation suggests that distance learning technology may hold potential for facilitating undergraduate education majors’ emerging constructivist perspective. 相似文献
