Who reads literature? Using national survey data, Nicholas Zill and Marianne Winglee analyze the audience for quality fiction, poetry, and drama—its size, potential for growth, demographic composition, and reading preferences. They discuss the factors that affect literary participation and investigate the mechanisms of these effects. They then examine the policy implications of their findings and suggest several ways that publishers, book-sellers, and librarians can use the survey results to increase the reading of quality fiction, poetry, and drama. 相似文献

Exploratory bifactor analysis (EBFA) represents a methodological advancement for implementing a bifactor model in exploratory factor analysis (EFA). However, little is known about how to properly employ the procedure. The current rotation criteria available for EBFA make it more likely to “get stuck” in local minima, contributing to possible group factor collapse, than more traditional EFA rotations. Thus, getting a proper solution is a more complex and involved process than typical EFA and may require a sensitivity analysis. This article examines EBFA through a sensitivity analysis and subsequent simulation of parameters thought to contribute to group factor collapse. Results support the use of sensitivity analysis, as the problematic variable was shown to greatly increase the likelihood of factor collapse. The hypothesis that estimation start values contribute to factor collapse was not supported. Accompanying R syntax for all analyses are provided to facilitate reproducibility. 相似文献

Slide shows presented with software such as PowerPoint or WordPerfect Presentations can trap instructors into bad teaching practices. Research on memory suggests that slide-show instruction can actually be less effective than traditional lecturing when the teacher uses a blackboard or overhead projector. The author proposes a model of classroom teaching that capitalizes on the advantages of slide shows without the pedagogical disadvantages. 相似文献

Search engines and other text retrieval systems use high-performance inverted indexes to provide efficient text query evaluation. Algorithms for fast query evaluation and index construction are well-known, but relatively little has been published concerning update. In this paper, we experimentally evaluate the two main alternative strategies for index maintenance in the presence of insertions, with the constraint that inverted lists remain contiguous on disk for fast query evaluation. The in-place and re-merge strategies are benchmarked against the baseline of a complete re-build. Our experiments with large volumes of web data show that re-merge is the fastest approach if large buffers are available, but that even a simple implementation of in-place update is suitable when the rate of insertion is low or memory buffer size is limited. We also show that with careful design of aspects of implementation such as free-space management, in-place update can be improved by around an order of magnitude over a naïve implementation. 相似文献

In this paper we report the results of a study which investigated the affordances of multi-user virtual environments (MUVEs)
for collaborative learning from a design perspective. Utilizing a mixed methods approach, we conducted a comparative study
of the effect of varying representational and interactional design features on a collaborative design activity in three online
synchronous environments. We compared environments featuring multiple modes of interaction (MUVEs), shared representations
(text chat and 2D still images) and text-only features. Sixty-one students enrolled in an undergraduate course on Child Development
participated in the study. Participants were asked to design a theoretically-based, developmentally appropriate, preschool
classroom setting. Students were randomly assigned to one of three online learning environments that provided varying levels
of representation and interaction. Significant differences in collaborative problem solving interactions were found. Participants
in the shared representations + text condition evidenced stronger learning outcomes as regards substantive discussion and
integration of child development concepts; while participants in the MUVE condition reported the most enjoyment with the experience.
These findings are explained by the concepts of representational guidance, representational bias, educational affordances
and interface design metaphors. Suggestions for the design of MUVEs for collaborative learning are provided. 相似文献

This article provides the final results of a 3‐year study that sought to discover whether early career researchers (ECRs) were the harbingers of change with respect to scholarly communications. Over a hundred science and social science ECRs from seven countries, spanning three continents, were depth‐interviewed annually for 3 years (2016–2018) about their attitudes and behaviours with respect to 23 scholarly issues and activities (aspects). In order to provide an accessible overarching assessment of an extremely large and complex dataset, the interview data were categorized according to the strength and direction of change exhibited and the trends and points of interest raised. Results show that all ECRs have changed in one way or another, and a small minority has changed greatly in both attitude and practice and that collaboration and research impact are the scholarly aspects where most changes have occurred, and the greatest cause of change is not so much new technology as a change of jobs. 相似文献
