A place-to-place migration study of first-time freshmen in American four-year colleges and universities presents student migration patterns for each of the fifty states and the District of Columbia in Fall 1986. Migration patterns of all first-time students are reviewed, but the focus of the study is first-time freshmen, the most critical population for institutional enrollment management. State-to-state matrix tables are presented that show where students come from and where they go to school for all fifty-one locations by sector of control (i.e., public and private).Presented at the 29th Annual Forum of the Association for Institutional Research, Baltimore, Maryland, May 2, 1989.  相似文献

The English orthography represents both phonemes and morphemes, implying that sensitivity to each of these units could play a role in the acquisition of decoding skills. This study offers some new evidence about sensitivity to morphemes and the decoding skills of American children in grades three to six. It focuses on knowledge of derivational suffixes, which is examined with sentence completion and sentence acceptability tasks that manipulate the suffixes in real words (e.g., electric, electricity) and nonsense derived forms (e.g., froodly, froodness). Both written and spoken materials are considered over the course of two experiments in which the children also received various reading tests, as well as tests of phonological awareness, vocabulary and intelligence. The results indicate that knowledge of derivational suffixes increases with grade level, along with decoding ability and phoneme awareness. Path analyses further reveal that, although there is a consistent correlation between performance on the derivational suffix materials and phoneme awareness and decoding ability, performance on the derivational suffix materials makes an independent and increasing contribution to decoding ability throughout the higher elementary grades.  相似文献

This study aimed to analyse the association of different components of physical fitness, body composition, cardiometabolic markers and the Mediterranean diet with bone mineral density (BMD) in perimenopausal women, and to test which of these components are independently associated with BMD. The sample comprised 197 perimenopausal women (52.6 ± 4.5 years). Physical fitness was assessed with the “Senior Fitness Test” battery and the handgrip strength and Bruce tests. Fat and lean mass and BMD were measured using dual-energy X-ray absorptiometry. We analysed the markers of metabolic syndrome, C-reactive protein, and components of the Mediterranean diet. Handgrip muscle strength (β = 0.212, P = 0.005), body weight (β = 0.244, P = 0.001), BMI (β = 0.180, P = 0.011) and lean mass (β = 0.379, P < 0.001) were positively associated with BMD. No associations were observed between cardiometabolic markers or the Mediterranean diet with BMD (all P > 0.05). When all relevant indicators of BMD were simultaneously considered, lean mass was the only 1 showing an independent association with BMD (β = 0.392, P < 0.001), explaining 14% of the BMD variability. In conclusion, muscle strength might be a marker of BMD in perimenopausal women. However, lean mass was the only factor independently associated with BMD. Future research to determine whether increasing lean mass through specific exercise-based interventions contributes to increasing BMD is warranted.  相似文献

Research Findings: The purpose of this exploratory study was to examine the relationship between classroom age composition and preschoolers’ vocabulary gains over an academic year and also to examine whether these relations were moderated by classroom quality. In this study (N = 130 children in 16 classrooms representing a subset of all children enrolled in these classrooms), results showed a significant cross-level interaction between classroom age composition and children's age, suggesting positive effects of greater variance in classroom age composition for younger but not older children. The interaction between behavior management (1 dimension of classroom quality) and classroom age composition was also significant, indicating that a wider distribution of classroom age composition was positively related to children's vocabulary gains within classrooms characterized by better behavior management. Practice or Policy: Findings underscore the importance of children's social interactions with more knowledgeable conversational partners in promoting their vocabulary development and signify the need to help teachers learn how to manage children's behaviors so as to provide a classroom that is optimal for child learning.  相似文献

This article describes a CD-ROM test disc project planned to gain firsthand knowledge of the production process, and to deliver a disc that will be used to analyze the potential market for full-text publications on CD-ROM. It describes getting started in the field, details the project planning process, and explains how to gather resources, schedule the project, and develop a work breakdown schedule. In this kind of project,task definition andcollaboration with other organizations are the crucial components for success. Virginia Meade led the team that produced Bellcore’s first CD-ROM disc. She has worked as a senior project manager in the Information Management Services division at Bellcore for the past three years, and chaired the Information Technology district’s electronic publishing services group.
