These two studies explored 3‐ and 5‐year‐olds' evaluation of noncircular and circular explanations, and their use of such explanations to determine informant credibility. Although 5‐year‐olds demonstrated a selective preference for noncircular over circular explanations (Experiment 1: Long Explanations; Experiment 2: Short Explanations), 3‐year‐olds only demonstrated a preference for the noncircular when the explanations were shortened (Experiment 2). Children's evaluation of the explanations extended to their inferences about the informants' future credibility. Both age groups demonstrated a selective preference for learning novel explanations from an informant who had previously provided noncircular explanations—although only 5‐year‐olds also preferred to learn novel labels from her. The implications and scope of children's ability to monitor the quality of an informant's explanation are discussed. 相似文献

Purpose: Prenatal exercise is a health behavior that is receiving growing attention amid concern that women in Western societies are gaining excess weight during pregnancy and contributing to future obesity in both the mother and child. In this article, we draw on insights from the fields of social epidemiology and social theory of the body to examine existing prenatal exercise interventions and to propose a multidimensional framework intended to guide future theorizing and intervention design. Method: A scoping review of existing prenatal exercise programs and interventions focused on controlling gestational weight gain was conducted. Articles published prior to January 2017 were obtained from PubMed and CINAHL, and relevant articles were identified (n = 62) using specified inclusion and exclusion criteria. Identified articles were further analyzed to classify the level(s) of the socioecological model targeted in the intervention or program. Results: The majority of existing interventions target intrapersonal factors during pregnancy and do not attend to the role that cumulative exposure of social and structural disadvantage over the lifetime—not just during the prenatal period—plays in shaping health outcomes. In response, a multidimensional framework is proposed that includes key concepts that facilitate a life-course perspective, as well as attention to the integration of biological and social factors as they relate to health and health-related behaviors. Conclusion: Efforts to promote prenatal exercise and to improve maternal and infant health should attend to how systemic inequality impacts women’s health. 相似文献

We report a microfluidic blood-brain barrier model that enables both physiological shear stress and optical transparency throughout the device. Brain endothelial cells grown in an optically transparent membrane-integrated microfluidic device were able to withstand physiological fluid shear stress using a hydrophilized polytetrafluoroethylene nanoporous membrane instead of the more commonly used polyester membrane. A functional three-dimensional microfluidic co-culture model of the neurovascular unit is presented that incorporates astrocytes in a 3D hydrogel and enables physiological shear stress on the membrane-supported endothelial cell layer. 相似文献

Play school is an icon of Australian children's television and an important part of Australian life – this programme, perhaps more than any other, has taken and continues to take centre stage in our living rooms and social worlds as young children. Play school is invested with an enormous amount of cultural capital and hence plays a significant role in the way that children engage and learn about social interaction, life and values in Australian culture. Aimed at preschoolers under the age of five, everything in the programme is done to relate as closely as possible to the social world and developmental level of the child and thereby assist their social, psychological and cognitive development. Through a combination of songs and dances, stories, dress up games and moments to ‘look through the window’ into the real world outside Play school, children are presented with a variety of sounds and images to engage with social concepts. In this paper we explore discourses of race, otherness and Indigeneity on Play school by deconstructing Aboriginalist images and representations featured on the programme and in doing so ask questions about the types of ‘race making’ that this programme engages in. 相似文献

Studies that examined copy‐cover‐compare (CCC) and variations of this procedure were reviewed and analyzed. This review revealed a substantial number of studies that validated the use of CCC across spelling and math skills and across students with and without disabilities. A meta‐analysis of findings indicated that CCC and variations of this procedure were effective for helping students acquire and become fluent in academic skills. The strongest effects were evident when CCC and variations of this procedure were combined with other evidence‐based instructional components. Limitations, future directions for research, and recommendations for practice are offered. © 2011 Wiley Periodicals, Inc. 相似文献

Indigenous Australian postgraduate students experience different barriers from those encountered by non-Indigenous students. In the transition from undergraduate to postgraduate study, Indigenous students are more likely to come from disadvantaged socioeconomic backgrounds, have lower personal incomes and lack family and other networks supportive of engagement with tertiary, and especially postgraduate, study. While there is a growing literature on Indigenous participation in higher education, with the exception of a few notable examples, there is little known about the effectiveness of support mechanisms and issues for Indigenous students undertaking postgraduate study. Drawing on interviews with current and past Indigenous postgraduate students at The University of Queensland, this paper problematises the postgraduate experience for Indigenous Australian students, identifying common themes in their accounts. It also discusses one of the outcomes of the project along with planned future developments that aim to provide better support for Indigenous Australian postgraduate students at The University of Queensland. By knowing and acting upon the kinds of mechanisms that can assist Indigenous postgraduate students, the disparity between Indigenous and non-Indigenous student participation in postgraduate study can begin to be addressed. 相似文献

Positive behavioral interventions and support (PBIS) is a multitiered framework for behavioral support that is being increasingly implemented in schools. Although research has linked PBIS to improved student outcomes, less research is longitudinal and considers both academic and behavioral outcomes. This study examined the relationships between changes in school‐wide (i.e., Tier I) PBIS implementation level and changes in disciplinary and achievement outcomes over a 2‐year period. Participants included 85 Ohio schools with data on PBIS implementation fidelity (from the tiered fidelity inventory, or TFI), out‐of‐school suspensions (OSSs), and statewide achievement tests for the 2015–2016 and 2016–2017 school years. Linear regressions were conducted to examine the degree to which changes in TFI Tier I scores predicted changes in OSS and achievement scores when controlling for school‐level demographic variables that also were related to the outcome variables. Changes in TFI Tier I scores was found to significantly predict changes in OSS per 100 students but not changes in achievement scores. 相似文献

ABSTRACTIn this commentary, pedagogical reflection is examined through the lens of a practitioners’ personal memories of childhood play. The telling of these stories uncovers and describes the ways in which teachers’ personal play histories and their reflections upon them could inform their facilitative relationship to, provision for, and perceptions of dramatic play in their classroom. The term play history is not limited to only childhood memories, rather, it can be further clarified as memories of and experiences with play as children, young adults, and as grown practitioners. Space for both pre- and in-service teachers to explore and examine relationships and experiences with play provides a platform for acknowledgement of their pasts in relation to how they think about, allow for, and engage in play now as a professional. 相似文献
