Cataloging has seen substantial change since 2000, and the cataloging of maps, geospatial data, and other cartographic resources is no exception. The pace and scale of change, tied to the evolution of technology and cataloging/metadata standards, have been swift and broad. This paper highlights the most important changes and trends in the cataloging of cartographic resources during the first thirteen years of the twenty-first century through a review of the published literature and summarizes the state of map cataloging today. The author concludes by proposing future directions for research and practice.  相似文献

Electronic monographic series display a complex mix of the characteristics of electronic serials, electronic books, and print monograph series. Because many cannot be managed via the typical tools and services used to manage electronic resources, providing title-level, or analytic cataloging presents challenges above and beyond the usual challenges for e-resources. This article enumerates those challenges, proposes a set of criteria for making analysis decisions for e-monograph series, and suggests other directions libraries might pursue to provide catalog access to this important category of resources.  相似文献

The majority of early education programs promote children’s learning through a mix of experiences in child- and teacher-managed contexts. The current study examined time spent in child- and teacher-managed contexts and the nature of children’s experiences with teachers in these contexts as they relate to children’s skill development. Participants were preschool children (N = 283, M age = 52 months, 48% girls, 70% Mexican or Mexican American) from families of a lower socioeconomic status. Observations captured children’s time in child- and teacher-managed contexts and experiences with teachers in each context. School readiness was assessed directly and through teacher reports. Research Findings: Time spent in teacher-managed contexts was positively related to children’s academic and social skill development. Experiences in child-managed context predicted vocabulary, math, and social skills when teachers were directly involved with children. Overall, the findings suggest that teacher engagement is related to positive outcomes even during child-managed activities. Practice or Policy: Given these findings, preservice and professional development programs for early childhood educators should have a component that focuses on how to enhance the teacher’s role during child-managed activities.  相似文献

Learning irregular words involves mental marking of irregular letters in the spelling, a process not fully understood. In a within‐subjects experiment, we manipulated the type of scaffolding given to beginning readers to evoke mental marking. We pretested to sort 103 kindergarten and first‐grade participants into sequential decoders, who decode letter by letter, and hierarchical decoders, who recognise vowel patterns. In the control phase, children read irregular words in sentence contexts with minimal scaffolding. In the experimental phase, participants read additional irregular words in sentence contexts by ‘operating on the word’ to mark irregular letters. Results indicated that the experimental condition induced better untimed word reading, but it did not improve spelling or reading in a flash presentation. Hierarchical decoders were significantly more successful than sequential decoders in untimed word reading, spelling and reading in the flash presentation. These results suggest that learning hierarchical decoding predisposes readers to learn irregular words.  相似文献

Satisfying information needs with multi-document summaries   总被引:2,自引:0,他引:2  
Generating summaries that meet the information needs of a user relies on (1) several forms of question decomposition; (2) different summarization approaches; and (3) textual inference for combining the summarization strategies. This novel framework for summarization has the advantage of producing highly responsive summaries, as indicated by the evaluation results.  相似文献

In celebration of Lamaze International's 50th anniversary, reviewers share their thoughts on some classic Lamaze resource materials and how their content relates to today's viewpoints on birth and childbirth education. Although some of the material may be outdated, all of the resources offer timeless insights as well as a unique view on the history of childbirth education. The following topics are addressed: past cultural views of birth; advocacy for change in birth practices; Lamaze method; pioneers in childbirth; importance of childbirth education; and birth advocacy.  相似文献

The improvement of ecological validity of laboratory research studies has recently come to the forefront of technology with virtual reality scenarios. The purpose of this study was to assess differences between unanticipated and anticipated lower extremity biomechanics while performing a sidestep cutting task. A visualization software was developed for this purpose, which would recreate a soccer game situation for use in a laboratory setting. Thirteen participants volunteered for this study. Lower extremity biomechanical data were collected with a VICON motion analysis system and two force plates, under anticipated and unanticipated conditions while performing a sidestep cutting task. Paired t-tests were conducted to assess possible differences between conditions. Alpha level was set a priori at 0.05. We found an increased knee adduction angle (unanticipated: -7.2 +/- 5.30 degrees; anticipated: -4.0 +/- 5.3 degrees), and knee internal rotation (unanticipated: 8.1 +/- 4.7 degrees; anticipated: 5.2 +/- 6.5 degrees) when performing the unanticipated condition (p < 0.05). The methodological approaches for studies investigating the factors possibly associated with ACL injury may need to take into account the laboratory environment and how the task(s) are presented to the participants.  相似文献

The purpose of this study was to use the marketing concept of segmentation in a post-secondary context in order to gain a better understanding of undergraduate students. Most post-secondary institutions segment their learners in traditional ways based on demographic characteristics such as age, year of program, gender, special needs, and grade point average. The establishment of identifiable learner-based segments is a unique, and arguably a critical, first step which can be of benefit to institutions as they develop recruitment strategies and academic programs that best serve the needs of their unique mix of undergraduate learners.Partners in Planning and focuses upon strategic development and transformation in the public and not-for-profit sectors, marketing, and product introduction  相似文献
