The authors examined whether math fluency was independent from untimed math and from reading using 314 pairs of school-aged twins drawn from the Western Reserve Reading and Math Projects. Twins were assessed through a 90-min home visit at approximately age 10 and were reassessed in their homes approximately 1 year later. Results suggested that the shared environment and genetics influenced the covariance among math fluency, untimed math measures, and reading measures. However, roughly two thirds of the variance in math fluency was independent from untimed math measures and reading, including reading fluency. The majority of this independent variance was the result of genetic factors that were longitudinally stable across two measurement occasions. These results suggest that math fluency, although related to other math measures, may also be a genetically distinct dimension of mathematics performance. 相似文献

Taking the present crisis of the Canadian Service of Admission to College and University as a starting point, the authors examine the history of SACU, which in 1971 was still a comparatively efficient organisation. Changes in the wider society, such as growing provincialism in Canada as well as stagnation or decline in enrolment together with a broader acceptance of the philosophy of open admission, have led to a drastic decline in the number of participants in the tests and to severe criticism of the predominantly selective function of SACU. It is felt that a reorientation of the testing activities of SACU should be in the direction of distributive and counselling functions, thus adopting the 1970 recommendations of the Commission on Tests of the American College Entrance Examination Board. 相似文献

Summaries English In recent years problems facing humankind have become more complex and challenging and have increasingly involved science and technology. While the public, generally, has been inadequately informed about such scientific and technical issues, public understanding of issues at the interface of science, society, and technology are an essential part of the resolution of societal problems. This paper outlines specific ways to promote understanding enabling individuals to participate more responsibly in enlightened democratic decision‐making responsive to societal needs. A systematic scheme is outlined with examples from two science education centres at tertiary institutions through activities including teaching, outreach, curriculum development, and research. 相似文献

In a previous issue of Knowledge Management Research & Practice (KMRP), we analysed the content and keywords of all articles published in the first decade of KMRP. With this article, we extend our preliminary analysis to the citation and co-citations made by these articles. The study covers all the 256 articles published. The most cited article was A dynamic theory of organisational knowledge creation by Nonaka. The most cited KMRP article was by Nonaka and Toyama: The knowledge-creating theory revisited: knowledge creation as a synthesizing process. The co-citation analysis of the 100 most cited articles in KMRP publications showed that four groups of topics emerged, one around communities and situated learning, the second group around networks, knowledge transfer and research methods, a third group around the foundations of knowledge management and a fourth group around intellectual capital. 相似文献

Comprehensive reviews of child death are increasingly conducted throughout the world, although limited information is available about how this information is systematically used to prevent future deaths. To address this need, we used cases from 2005 to 2009 in the U.S. National Child Death Review Case Reporting System to compare child and offender characteristics and to link that information with actions taken or recommended by review teams. Child, caretaker, and offender characteristics, and outcomes were compared to team responses, and findings were compared to published case series. Among 49,947 child deaths from 23 states entered into the Case Reporting System during the study period, there were 2,285 cases in which child maltreatment caused or contributed to fatality. Over one-half had neglect identified as the maltreatment, and 30% had abusive head trauma. Several child and offender characteristics were associated with specific maltreatment subtypes, and child death review teams recommended and/or planned several activities in their communities. Case characteristics were similar to those published in other reports of child maltreatment deaths. Teams implemented 109 actions or strategies after their review, and we found that aggregating information from child death reviews offers important insights into understanding and preventing future deaths. The National Child Death Review Case Reporting System contains information about a large population which confirms and expands our knowledge about child maltreatment deaths and which can be used by communities for future action. 相似文献

ABSTRACT Participatory budgeting (PB) has emerged as a tool for empowering marginalized communities and advancing social justice through public deliberation and advocacy. However, public deliberation scholars have contested the appropriate roles of social justice, activism, and equity. PB bridges deliberation, advocacy, and equity, as it strives to accomplish social change. We detail how the first cycle of Greensboro PB navigated tensions between residents who sought social change and government officials who wished to maintain the status quo. We argue PB is an example of public deliberation that fosters social justice sensibilities among participants and conclude with applied recommendations for design improvements. 相似文献

ABSTRACTThe tomb of Tutankhamen in the Valley of the Kings, Egypt, one of the major attractions of the World Heritage Site of Ancient Thebes and its Necropolis on the West Bank of modern day Luxor, is today a destination for mass tourism. Visitors to the tomb increase relative humidity, elevate carbon dioxide levels, and encourage natural ventilation which facilitates entry of dust into the tomb. These conditions negatively impact the wall paintings and remaining artifacts in the tomb and create an uncomfortable environment for visitors. The deposition of dust inside the tomb collects on uneven wall painting surfaces, obscures their legibility and necessitates cycles of cleaning, which in turn leads to further damage. Developing environmental management strategies in the tomb to counter the effects of visitors and mitigate dust entry is an important component of the collaborative project between the Getty Conservation Institute (GCI) and Egypt’s Ministry of Antiquities (MoA) to conserve the tomb. These included implementation of a filtered-air supply and exhaust ventilation system to stabilize the interior microclimate and reduce dust in order to improve visitor comfort and contribute to the long-term preservation of the tomb. 相似文献
