This article begins with an analysis of reliability and usability in the mathematical literature. Mathematical practice is seen to be adapted to very high standards in these respects, and quite sensitive to even modest declines in quality. Unfortunately most scenarios for the transition to electronic publication suggest serious loss of quality. This is a problem special to mathematics: other sciences are adapted to lower standards, and should be much less sensitive to changes. Some ways to prevent this decline are suggested. A condensed version of this article appeared inNotices of the American Mathematical Society, 42, 1, January 1995. Published with permission of the American Mathematical Society.  相似文献

Using a participatory learning approach, we report on the delivery and evaluation of a climate change and risk assessment tool to help manage water risks within the agricultural sector. Post-graduate water-professional students from a range of countries, from both developed and emerging economies were involved in using this tool. Our approach included participative learning tools – group discussion, software, and risk matrices. The materials developed met the needs of the students, allowing these students to incorporate their learning and adapt the package of materials for use in their home countries. Analysis of evaluations show that the tools and materials are particularly useful and emphasizes the need for sound learning materials and tools, funding to deliver training, and policy support to accelerate education and adoption of authentic climate change adaptation practices. The expected benefits for water professionals about climate change will be translated into improved socioeconomic and environmental outcomes if adopted.  相似文献

This article responds to attitudes about giftedness in M. Sapon‐Shevin's article, “Explaining Giftedness to Parents: Why it Matters What Professionals Say.” Giftedness is not a reward or a privilege, but an aspect of a child's individuality that should be understood and taken into account by the educational system. Gifted children's needs are not solely academic, and it is parents who are responsible for meeting those needs. They need information from as many sources as possible. They are also excellent sources of information themselves, so the relationship between professionals and parents should be reciprocal. This article also responds to some of Sapon‐Shevin's objections to the book Guiding the Gifted Child, (Webb, Meckstroth, Tolan, 1982). In the preparation of this article, the writer worked closely with coauthors James T. Webb and Elizabeth Meckstroth, whose pioneering work with the SENG Project at Wright State University provided the basis of Guiding the Gifted Child.  相似文献

Although the effectiveness of inoculation as a strategy for promoting resistance to attitude change is fairly well established, the potential of inoculation messages to offer cross-protection for related, but untreated, attitudes warrants additional attention from scholars. The reported study tested the “blanket of protection” conferred by inoculation. Participants (N = 118) were randomly assigned to read an inoculation message addressing a target topic and subsequently had their attitudes toward three related, but untreated, topics attacked. The results offer some evidence that inoculation messages can confer cross-protection for related attitudes. Participants in the inoculation condition reported greater perceptions of threat, greater counterarguing, and less attitude change in response to attacks than participants in the control condition for two of the three untreated topics. Counterarguing in response to attacks on untreated attitudes appears to be primarily responsible for cross-protection.  相似文献
