This study examines frequency, overlap, and genetic and environmental influences on sleep difficulties, which are understudied in school-aged children. The Sleep Self Report and the Children's Sleep Habits Questionnaire were completed by 300 twin pairs (aged 8 years) and their parents. Child report suggested more frequent sleep problems than parent report (e.g., regular sleep onset delay was reported by 45% of children and 17% of parents). Associations between most of the sleep difficulties were small but significant (e.g., r(s)=.16 for parent report of bedtime resistance and sleep onset delay). Twin correlations based on parent reports suggest greater genetic influence (M=50%) than those based on child self-report (M=18%). Possible rater effects should be considered when evaluating children's sleep problems. 相似文献

In Experiment 1, a potentiation paradigm was used to test the relative influence of odor and taste with two 2 basic tastants
(i.e., salt and sweet) in conditioned aversion learning. Experiment 1 showed that aversions to tastants (salt or sweet presented
in a manner by which it could be tasted) were established only in subjects trained with the tastant, not the odor (i.e., salt
or sweet presented in a manner by which it could not be tasted). Experiment 2 demonstrated, with a sensory preconditioning
procedure, that the expression of an aversion to tastants was dependent on previous tastant experience prior to odor aversion
training. These results suggest that while subjects can smell salt and sweet solutions, these odors are neither sufficient
nor necessary for the expression of a conditioned tastant aversion. 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

To counteract what we see as a growing research-reporting concern, we propose the following editorial-policy change regarding the content of primary research articles in educational research journals: Contributors should restrict their discussion and conclusions to their data and not offer recommendations for educational practice nor speculate about the educational policy implications of their research. We believe that this change will be beneficial for maintaining a separation between evidence and opinion concerning the legitimate warrants of empirical research. We suggest viable accompaniments and alternatives to authors offering practical recommendations and policy speculations in primary-research journal articles. Among these is to rely on all sources of evidence, including systematic research syntheses based on the aggregated contribution of multiple research studies from different sources, with recommendations for practice tailored to specific situations so that both their validity and utility will be increased. It is hoped that our proposed policy change will initiate a conversation among researchers, editors, reviewers, and educational-policy experts with respect to the scope and purpose of primary research journal articles. 相似文献

ABSTRACTContemporary museums must balance their roles as commercial entities and repositories of various, and often dissonant, heritages and histories. Sports museums in particular often have clear commercial and nostalgic aims, particularly through tourist visitation, though the extent to which they represent more challenging narratives remains unclear. This paper examines how one of the most famous sports museums in the world, the National Baseball Hall of Fame (NBHF) in Cooperstown, New York, balances its dual role as tourist attraction and repository of baseball's sometimes checkered past. It was found that different sections of the museum provide greater or lesser degrees of engagement with more controversial issues, although the commercial outputs and appeal of the museum remains clear throughout. Utlimately, the NBHF demonstrates that balancing veneration and critique in collections can be commercially prosperous, and can provide a template for other sport and popular culture museums who may be wary of incorporating more challenging narratives in their exhibits. Furthermore, the symbiotic relationship between the Hall of Fame and the village of Cooperstown, particularly in creating and maintaining cultural and economic outputs, requires further exploration. 相似文献

This review was conducted to identify articles written about Geographic Information Systems (GIS) services offered in the United States (US) and Canadian university and college libraries. In the early 1990's, the Association of Research Libraries (ARL) GIS Literacy Project, in partnership with Environmental Systems Research Institute (ESRI), helped enable ARL member libraries to create GIS services within their libraries. By the mid to late 1990's, librarians from academic institutions began to write articles that discussed how their library developed GIS services and the components involved with operating a GIS service. Writing about GIS services in academic libraries continued on into the 2000's and 2010's. This review of the literature will document the areas of staffing, service, technology, and data provision for GIS service units from three decades (1990's, 2000's, and 2010's). 相似文献

This study analyzes Boston Mayor Thomas Menino’s rhetoric via Twitter following the Boston Marathon Bombing, exploring how a leader engaged in crisis communication using social media. Guided by restorative rhetoric, we examine how Menino included strategic communication (alleviate risk and restore public safety) and humanistic communication (focusing on the more substantive issues of crisis leadership) in his tweets. Our analysis is grounded in the five tenets of restorative rhetoric as a theoretical lens: initial reaction; assessment of the crisis; issues of blame; healing and forgiveness; and corrective action and rebuilding through a rhetorical vision. The findings demonstrate the utility of social media in aiding leaders as they provide critical information and guidance amid high uncertainty while also initiating the healing process, including fostering resilience. 相似文献

This study investigated the influence of informational complexity and working memory capacity on problem-solving efficiency.
We examined two predictions of thesituational efficiency hypothesis, which states that the efficiency of problem solving varies as a function of situational constraints. One prediction is that
informational complexity affects problem-solving efficiency. A second prediction is that working memory capacity affects problem-solving
efficiency. Students completed a working memory task and solved abstract and concrete syllogisms. Participants solved abstract
syllogisms more accurately than concrete syllogisms and spent more time solving abstract syllogisms. Thus participants demonstrated
greater problem-solving efficiency when solving concrete syllogisms. Results indicate that there is a trade-off between problem-solving
accuracy and problem-solving time when information differs with respect to informational complexity, a phenomenon we refer
to as theefficiency paradox. Working memory capacity did not affect accuracy or efficiency. The results support the conclusion that problem-solving efficiency
is situational and a function of the complexity of information. Educational implications and directions for future research
are suggested. 相似文献
