铅锌矿产资源开发重金属污染风险评价

在论述环境风险评价的概念、理论和方法的基础上,通过对某典型铅锌矿山重金属污染程度、重金属毒性响应系数和生态危害系数的计算与探讨,建立了铅锌矿山重金属生态风险评价指标体系.根据所建立的指标体系,计算了每个样点的生态风险指数,结果认为该矿山总体环境质量很差,重金属污染极其严重.     

作物秸秆资源的利用及其影响因素--以山西省夏县为例

作物秸秆资源的利用对提高食物安全,减轻环境污染,促进农业可持续发展具有重要意义.通过对农户的调查,分析了山西省夏县的秸秆利用途径,对该县秸秆利用现状进行了评价,并分析了造成这种现状的原因.结果表明,夏县作为典型的"小麦-玉米"二熟农作区,秸秆利用效率较高,其中小麦秸秆主要用于工业原料、饲料和还田,玉米秸秆则主要用于饲料和弃置堆放.这种利用方式与造纸业发展、传统的牲畜饲喂方式、农业机械化发展和气候特点有关.最后提出了进一步高效利用秸秆资源的建议.

发展旅游对海岛环境的影响及应对策略研究

海岛作为一个独特的地理单元，旅游资源丰富，发展前景广阔，但在海岛旅游迅速发展的同时，海岛环境也受到极大的影响。而海岛又是环境敏感地区，生态环境脆弱，一旦破坏就难以恢复，所以重视海岛旅游出现的环境问题，加强对海岛环境的保护，促进海岛经济的可持续发展应引起广泛的关注和重视。     

Knowledge, values, uses and management of the Araucaria araucana forest by the indigenous Mapuche Pewenche people: A basis for collaborative natural resource management in southern Chile

One of the most important endemic tree species of Chile and at the same time one of the most endangered ones is Araucaria araucana (Mol.) C. Koch, the monkey‐puzzle tree. It grows in the Andes Mountains, homeland of the indigenous Mapuche Pewenche people who depend on this tree. This paper is based on field research that investigated the ecological knowledge, uses and management of the Araucaria araucana forest by indigenous Mapuche Pewenche people based on the socio‐cultural, spiritual and ecological relationships they have with the Araucaria forest, to find out how indigenous people and their knowledge could contribute to sustainable Araucaria forest management. A Mapuche Pewenche community located in the IX region of Chile contributed to this study. Based on the analyses this paper illustrates the nature of indigenous ecological knowledge of Araucaria araucana on the one hand, and its utility in native forest management on the other. The research shows that the Mapuche Pewenche hold ecological knowledge and conduct practices to manage their Araucaria forest in a balanced way. They conserve and use forest biodiversity at one and the same time. This paper provides recommendations for sustainable Araucaria forest management and conservation strategies ex‐situ and in‐situ incorporating indigenous knowledge and scientific knowledge and for promoting a collaborative natural resources management.

Monsanto’s Biotechnology Politics: Discourses of Legitimation

Since the first product became commercially available in 1995, biotechnology has become the fastest growing crop technology, dominating large shares of the global agricultural market. The development of biotechnology, however, has given rise to questions regarding human and ecological safety, culminating in local and global political battles. While researchers interested in biotech politics have focused on areas such as media framing, social movements, and campaign work, less attention has been paid to how the industry has historically promoted and legitimized this swift proliferation. In this study, we conduct a discourse analysis of documents available on live and archived websites to discern the legitimation strategies employed by one important corporate actor, Monsanto. Findings show that for nearly two decades, Monsanto consistently employed discursive resources that concealed details about actors and action, reflected trends among experts in global sustainability discourse, and reshaped narratives to promote itself, products, and biotechnology in general.     

Rested,friendly, and engaged: The role of daily positive collegial interactions at work

This diary study examined within‐person effects of positive work and off‐work experiences on daily work engagement. Assessing the gain cycle assumption of conservation of resources theory, we investigated the relationship of nighttime recovery experiences and subsequent resources including elevated sleep quality and morning positive affect; the relationship of morning positive affect with positive collegial interactions and subsequent work engagement; and the relationship of work engagement with nighttime recovery experiences. Sixty‐nine employees completed 3 daily questionnaires over 5 consecutive working days. Multilevel analyses revealed that sleep quality positively predicted morning positive affect, which in turn predicted work engagement directly and also indirectly through having positive interactions with colleagues. Work engagement positively predicted nighttime recovery experiences, whereas nighttime recovery experiences were not related to sleep quality or morning positive affect the next day. Overall, on days after a good night's sleep, individuals feel more positive, bring this positivity to their workplace, reach out to their workplace colleagues, and are in turn more likely to be engaged in their work. Additionally, on days when individuals experience higher levels of positive collegial interactions at work and in turn higher work engagement, they are likely to enjoy better recovery experiences.
