Knowledge of appropriate behaviour during an earthquake is crucial for prevention of injury and loss of life. The Israeli Home Front Command conducts a yearly earthquake education programme in all Israeli schools, using three types of educational interventions: lectures, drills and a combination of the two. The aim of this study was to evaluate the effectiveness of these interventions in providing students with knowledge. We distributed a questionnaire to 2,648 children from the 5th and 6th grades in 120 schools nationwide. Knowledge scores for both 5th and 6th grades were increased, regardless of type of intervention, compared to the non-exposure group. A combined intervention of lectures and drills resulted in the highest knowledge scores. Our findings suggest that for the age group studied a combination of lectures and drills will likely prepare students best for how to behave in the event of an earthquake.  相似文献

Double-consciousness pervades the workplace experiences of minority professionals. Prior research captures various manifestations of double-consciousness in the workplace, yet much of what we know comes from understanding the experiences of minority professionals in predominantly White workplaces. Inherent in conceptions of double-consciousness is the sense of twoness in one's self concept that arises from seeing oneself through the eyes of both the predominantly White profession and one's own racial community. In this study, we examine contrasts as well as commonalities in experiences of double-consciousness across different social contexts in the socialization of minority scientists-in-training. We draw from qualitative data collected from 64 individuals (including 39 underrepresented minority doctoral students, and 25 faculty, staff, and administrators) in science, technology, engineering, and mathematics (STEM) doctoral programs in both predominantly White and historically Black institutions to examine and compare the factors across different contexts that influence how minority scientists-in-training are able to express their emerging professional identity. Our findings reveal how minority scientists-in-training experience twoness as both a struggle and a strength, and we develop an inductive model of how different socializations influence the double-conscious professional self-expressions of minority scientists in training.  相似文献

This paper reports on the results of a qualitative study on the responses of Chinese school children in one junior middle school and their parents to China's post‐disaster school relocation policy. The sample comprised 22 pairs of parent–child dyads and two pupils whose parents could not be contacted. The study results were reported using Chambers and Wedel's (2009) conceptual framework, which delineates the fundamental elements of a policy. Content analysis was used to generate themes related to policy elements, such as goals, benefits and services. Both repetitive themes and idiosyncratic perspectives were reported so as to present a diversity of views. Despite adjustment difficulties and administrative problems reported by the study participants, the policy attention given to the rapid restoration of formal schooling for children was generally appreciated. The move back to the new school was greeted with cheer.  相似文献

矿工不安全行为致因分析及控制   总被引:1,自引:0,他引:1  
探讨和研究人的不安全行为产生原因及控制已成为预防矿难发生的热点问题。针对现场获得的矿工不安全行为(“三违”)事件,从生理和心理效价、经济效价、时间效价、法规执行成本、危险压力成本五个方面进行致因分析,采用模糊聚类方法,选取适当的阈值λ,将不安全行为的产生分为三个基本要素,即:安全知识不足、安全技能不够、安全意识淡薄。鉴于目前对“三违”人员通常采取行政处罚,以及对安全知识和技能的培训流于形式,未能杜绝三违的重复发生,提出了针对不安全行为成因进行针对性的安全教育模式,并且取得了良好效果。  相似文献

Environmental management and planning is now considered as a new field of professional expertise. There are even professional associations for interested professionals. To date, urban environmental management has been regarded as a subdiscipline of environmental management, but since the Rio Conference in 1992, with the new focus of urban management on environmental problems, it can itself be considered as a professional field. This paper traces the emergence of the field and tries to identify the new skills required for it. The question of formal training, in higher education, for a new type of professional is raised and discussed. It refers at length to an initiative taken by the Asian Institute of Technology (Bangkok) to propose and offer a new graduate programme in this discipline, and draws on the author's experience of an Asian workshop (Bangkok, May 1993) aimed at defining the need for such a new profession in Asia.  相似文献

SUMMARY

This paper focuses on efforts to promote environmental education and community mobilization around environmental issues in Hong Kong. It is primarily concerned with efforts directed at the broader community (i.e. the population as a whole) rather than with environmental education through formal school and college curricula. The paper draws on a recently completed study commissioned by the Environmental Campaign Committee, the principal source of financial support for such efforts undertaken by environmental NGOs, community groups and educational institutions in Hong Kong. The study examined how and to what effect the Committee had used its financial resources between 1994–1999. It also examined international experience with a view to recommending changes in the overall approach to environmental education and community mobilization initiatives and their funding in Hong Kong.

The paper suggests that the existing approach to community-wide environmental education and its funding in Hong Kong have suffered from various weaknesses, most notably the absence of an integrated and goal-oriented strategy, an over-reliance on a ‘top-down’ campaign-based approach, a failure to establish explicit linkages with the concept of sustainable development and to ground initiatives at the local neighbourhood and community levels, and a preoccupation with the financial inputs provided to support this work at the expense of effective monitoring and auditing of project outputs and benefits.  相似文献

Planning in sustainable development is believed to be an important element in allowing higher education institutions to set their goals and to commit themselves towards undertaking concrete actions and measures at all levels in order to implement sustainability. Yet, there is a paucity of research that has looked at the extent to which planning can support institutions of higher education to assess their performances and to determine whether the set aims have been met. This research gap needs to be met to allow a better understanding of how planning can help to promote the integration of the three components of sustainable development – economic development, social development and environmental protection in higher education. This paper explores the challenges for planning the sustainable development in higher education, also outlining the potentials lessons learned that could assist in improving Education for Sustainable Development efforts in Higher Education Institutions. Among its main results are the fact that many universities wish to pursue sustainable development, but their efforts are hindered by lack of institutional support and planning and limited emphasis on approaches, such as problem-based learning. The universities that are engaged in the field have to face many problems, varying from limited resources to lack of trained staff. As a result, integrated approaches to sustainability become difficult to implement. Finally, the paper has identified the fact that many opportunities offered mainstream developments, such as the UN Declaration ‘The World we Want’ or the UN Sustainable Development Goals are not being put to full use.  相似文献
