我国安全学科学历教育的困境与对策

我国安全形势严峻的重要原因是安全科技人才缺乏。安全学科学历教育作为我国安全科技高级人才培养的主要渠道之一,为国家造就和输送了大批安全科技人才。但是,由于安全学科学历教育体制没有很好适应市场经济的发展,遇到了不少难以解决的问题。依据对高校和煤炭企业调查所获得的资料,统计发现:目前我国安全学科学历教育所面临的主要问题是专业设置的局限性、培养目标的雷同性和课程设置的低通用性;社会对安全人才需求与目前高校安全专业招生和毕业生就业之间存在的突出矛盾。在详细调研和分析的基础上,提出了相应的安全人才后备队伍建设应采取的对策,即加大政府调控力度、实施“人才兴安”战略,深化教育教学改革、培养高素质安全人才。     

基于ArcIMS的旅游安全管理系统

结合旅游业的特点,即综合性、敏感性、涉外性或国际性,提出旅游安全管理系统应该包括:灾前的防范系统、灾时的抗灾系统以及灾后的评估善后系统3大部分的设计思路。将相应的旅游重大危险源监控系统的功能定为:以行政监察、社会监督、行业自律和应急救援体系为主的宏观管理系统。阐述了Web GIS的优点并推荐了一种构建Web GIS的新技术———ArcIMS,利用ArcIMS的系统构建的旅游安全管理系统具有功能健全、管理方便、系统成熟和安全可靠的诸多优点;同时整个系统的构建相对于其他Web GIS系统的开发而言,技术难度比较低、开发速度比较快,而且系统运行相对稳定,减轻了系统维护的负担。最后,结合旅游安全信息流的特点,具体阐述了运用ArcIMS作为旅游安全管理系统的平台的合理性和可行性。     

地球系统科学提出前我国科学界的某些思维

列举了在1988年美国提出"地球系统科学"前我国学者在该领域的某些思维:人与天地相应的观点,东亚大陆磁异常与我国人群健康关系的观点,天地生三位一体的观点,地球表层学的观点以及灾害系统的观点等.这些观点虽不如"地球系统科学"着眼于全球整体,但也包括了很大的系统,且不空洞.

The city as a refuge for insect pollinators

Research on urban insect pollinators is changing views on the biological value and ecological importance of cities. The abundance and diversity of native bee species in urban landscapes that are absent in nearby rural lands evidence the biological value and ecological importance of cities and have implications for biodiversity conservation. Lagging behind this revised image of the city are urban conservation programs that historically have invested in education and outreach rather than programs designed to achieve high‐priority species conservation results. We synthesized research on urban bee species diversity and abundance to determine how urban conservation could be repositioned to better align with new views on the ecological importance of urban landscapes. Due to insect pollinators’ relatively small functional requirements—habitat range, life cycle, and nesting behavior—relative to larger mammals, we argue that pollinators put high‐priority and high‐impact urban conservation within reach. In a rapidly urbanizing world, transforming how environmental managers view the city can improve citizen engagement and contribute to the development of more sustainable urbanization.     

Implications of human value shift and persistence for biodiversity conservation

Large‐scale change in human values and associated behavior change is believed by some to be the ultimate solution to achieve global biodiversity conservation. Yet little is known about the dynamics of values. We contribute to this area of inquiry by examining the trajectory of values affecting views of wildlife in North America. Using data from a 19‐state study in the United States and global data from the Schwartz Value Survey, we explored questions of value persistence and change and the nature of attitudinal responses regarding wildlife conservation issues. We found support, based on subjects’ ancestry, for the supposition that domination is a prevalent American value orientation toward wildlife that has origins in European Judeo‐Christian traditions. Independent of that effect, we also found indications of change. Modernization is contributing to a shift from domination to mutualism value orientations, which is fostering attitudes less centered on human interests and seemingly more consistent with a biocentric philosophy. Our findings suggest that if value shift could be achieved in a purposeful way, then significant and widespread behavior change believed necessary for long‐term conservation success may indeed be possible. In particular, greater emphasis on mutualism values may help provide the context for more collaborative approaches to support future conservation efforts. However, given the societal forces at play, it is not at all clear that human‐engineered value shift is tenable. Instead of developing strategies aimed at altering values, it may be more productive to create strategies that recognize and work within the boundaries of existing values. Whereas values appear to be in a period of flux, it will be difficult to predict future trends without a better understanding of value formation and shift, particularly under conditions of rapid social‐ecological change.     

The role of digital data entry in participatory environmental monitoring

Many argue that monitoring conducted exclusively by scientists is insufficient to address ongoing environmental challenges. One solution entails the use of mobile digital devices in participatory monitoring (PM) programs. But how digital data entry affects programs with varying levels of stakeholder participation, from nonscientists collecting field data to nonscientists administering every step of a monitoring program, remains unclear. We reviewed the successes, in terms of management interventions and sustainability, of 107 monitoring programs described in the literature (hereafter programs) and compared these with case studies from our PM experiences in Australia, Canada, Ethiopia, Ghana, Greenland, and Vietnam (hereafter cases). Our literature review showed that participatory programs were less likely to use digital devices, and 2 of our 3 more participatory cases were also slow to adopt digital data entry. Programs that were participatory and used digital devices were more likely to report management actions, which was consistent with cases in Ethiopia, Greenland, and Australia. Programs engaging volunteers were more frequently reported as ongoing, but those involving digital data entry were less often sustained when data collectors were volunteers. For the Vietnamese and Canadian cases, sustainability was undermined by a mismatch in stakeholder objectives. In the Ghanaian case, complex field protocols diminished monitoring sustainability. Innovative technologies attract interest, but the foundation of effective participatory adaptive monitoring depends more on collaboratively defined questions, objectives, conceptual models, and monitoring approaches. When this foundation is built through effective partnerships, digital data entry can enable the collection of more data of higher quality. Without this foundation, or when implemented ineffectively or unnecessarily, digital data entry can be an additional expense that distracts from core monitoring objectives and undermines project sustainability. The appropriate role of digital data entry in PM likely depends more on the context in which it is used and less on the technology itself.
