为使各高校能有效应对工程教育与应急管理的新一轮发展,在新工科建设与应急管理部成立背景下研究安全与应急管理专业学科的现状与发展趋势。阐述专业建设与学科建设的联系、区别和作用,在此基础上分析安全与应急管理专业学科发展现状、凝练专业建设核心4要素、完善安全学科体系、总结应急管理一级学科体系构建思路,分别提出基于“现在完成进行时”与“将来完成进行时”状态的安全、应急管理专业学科发展趋势。结果表明:安全专业发展趋势分行业安全与“大安全”2类,安全学科仍需完善学科体系和科学分支;应急管理的长远发展趋势是设立一级学科,从而推动应急管理专业高质量创新型发展。     

DNA Registers of Legally Obtained Wildlife and Derived Products as Means to Identify Illegal Takes

Abstract:  The exploitation and sale of wildlife species that are endangered in only part of their range present regulators with the critical challenge of separating legal from illegal takes. Wildlife DNA registers created from tissue samples of legally obtained individual wildlife specimens can address this problem by allowing managers to identify unregistered (presumably illegally obtained) specimens. We tested the effectiveness of the only current, fully operational wildlife DNA register of individual genetic profiles collected from legally caught minke whales ( Balaenoptera acutorostrata ). Twenty minke whale tissue samples collected at markets in Norway and 2 additional samples collected from beached minke whales in Denmark were genotyped at 12 loci used by the Norwegian minke whale DNA register. Genetic profiles of these samples then were compared against the 2676 individual profiles deposited in the Norwegian register. The high number of genetic markers used to identify individuals in our study allowed consistent matching of sample and reference profiles despite an overall error rate (due to experimental and interlaboratory data standardization) estimated at 0.015 per locus. Of the 22 test samples only the 2 Danish samples failed to match an existing profile in the Norwegian minke whale DNA register. Our results show that the basic principle of wildlife DNA registers can work in a real-life situation. The strength of wildlife DNA registers lies in their ability to unambiguously identify unregistered specimens with the aid of sensitive genetic methods that enable analysis of highly processed or degraded tissue samples. Our study also highlights a number of methodological problems such as laboratory errors and interlaboratory data standardization, which need be addressed to ensure a successful implementation of wildlife DNA registers.     

Boomerangs versus Javelins: How Polarization Constrains Communication on Climate Change

Political communicators work under the assumption that information provision, such as framing, may influence audiences and elicit some desired attitudinal or behavioral shift. However, some political issues, such as climate change, have become polarized along party lines, with partisans seemingly impervious to disconfirming information. On these highly polarized issues, can framing sway partisans to moderate their positions, or are partisans so motivated in their issue stances that framing fails? Using a variety of vignettes, and Republican climate change skepticism as a case, this article reports an experiment of how partisans respond to counter-attitudinal framing on a sharply polarized issue. Results indicate that Republicans are resistant to frames that encourage support of governmental action or personal engagement against climate change. There is strong evidence of motivated skepticism, given widespread backfire (or ‘boomerang’) effects and decreased attitudinal ambivalence following exposure to framing, suggesting that issue polarization may severely constrain attempts at communication.     

从环境类学术文献看中国环境教育存在的问题

根据我国环境科学类期刊上刊登的环境教育文献的比重和内容的调查结果来看，我国环境科学界对环境以重视程度与环境教育的重要性不成比例，环境教育研究的落后已成为制约我国环境教育可持续发展的关键问题。     

Place attachment and place identity in natives and non-natives

Place attachment is an affective bond that people establish with specific areas where they prefer to remain and where they feel comfortable and safe. Place identity, however, has been defined as a component of personal identity, a process by which, through interaction with places, people describe themselves in terms of belonging to a specific place. Most research has observed positive correlations between these variables in populations that have maintained ongoing interactions over long periods of time. This work presents two studies in which we compare place attachment to place identity in samples differentiated according to birthplace and length of residence, and the magnitude of these bonds to different places. The results of the first study revealed differences between intensity of attachment and identity depending on place of origin and place assessed. The second study found that identity and attachment tend to coincide in natives, while individuals from other places give higher scores for attachment than for identity. Results from the two studies have enabled us to consider that place attachment develops before place identity, at least in the case of the non-natives. Both studies reveal that bonds are stronger with the city than with the neighbourhood, but that attachment and identity with the island are stronger than either of them.

PROFESSIONAL WATER RESOURCES EDUCATION FOR THE FUTURE… ARE WE READY?1

ABSTRACT: Water resources professionals are being increasingly called upon to address complex problems which require the interaction of several individuals operating as a planning or implementation team. Education for water resources professionals must move to meet the demands of this mode of operation. To best prepare the student, educational programs must focus not only on technical competence but must also incorporate concepts of cooperative problem solving with individuals from a diversity of backgrounds as a part of the curriculum. Among strategies which may work are academic requirements outside of the technical specialty, modification of existing course materials, and inclusion of outside faculty as a part of departmental curriculum preparation.

Farming and Landscape Management: How French Farmers are Coping with the Ecologization of Their Activities

In Europe, an increasing share of public subsidies for food production is being transferred towards the production of goods and environmental services. Today, farmers hesitate between the quest for technical and economic performance, which has been the paradigm of their professional activities since the 1960s, on one hand, and taking account of the environmental concerns that have been imposed since the middle of the 80s, on the other. Is it possible for farmers to continue to work according to the paradigm of the producer of agri-food goods, and how do they react to the ecologization of their activities? In this paper, we will see the difficulties and sources of tension induced by landscape maintenance in the daily professional practice of the farmers. We will see that the professional identity of the farmers is profoundly brought into question by these changes (substitution of strictly “agricultural issues” by more general concerns such as “rural issues,” substitution of the farmer by the “ecologized” peasant...). The topic of landscape reveals social strains between farmers. It also raises the question of the legitimacy of farmers to define the sense of their activities by themselves. Finally we will see that environmental orientations do not systematically open up new prospects for all farmers; they sometimes contribute to increase the inequalities between farmers (financial support proportional to land property, marginalization of farmers who are less socially integrated...).
