环境伦理学的双重价值理论

环境伦理学坚持内在属性的理论,把价值看成是自然价值。自然价值被事物的内在属性所决定。它的存在,乃是自然自身创造性的一种结果。自然价值表现着自然自身的特质关系,它是一种客观价值。与人的评价系统无关。另一方面,环境伦理学又坚持了人的主体性,在罗尔斯顿那里,审美价值是需要人的主体介入才可以形成的,而人们的情感体验又是价值产生的基本条件。这样,环境伦理学也就确定了双重的价值关系,它的理论也就具有了二元论的倾向。     

从摩尔的理论看环境伦理学的自然价值观

摩尔在伦理学原理一书中,首次分析了传统伦理学关于善的那种性质。指出善并不是一种自然之属性。而是一种非自然的属性。在严格的意义上说,善是不可定义的。并认为传统伦理学是犯了一种自然主义的谬误。摩尔的理论也波及到环境伦理学,特别是罗尔斯顿的自然价值理论受到了挑战。罗尔斯顿对自然主义的批评作出了回应。他把伦理义务的条件置于科学规律之前,并站在自然主义的立场上,指出自然界的生态平衡才是一切价值的基础。     

环境伦理学目的性理论的内在矛盾

环境伦理学的目的性理论有其内在的矛盾。一是它没能说清自然的整体目的与个体目的之间的关系,它们是从属的关系,还是各自独立的关系?二是它在坚持自然目的性的时侯,忽略了人的精神目的性。当它去解释自然事件时,用的是前一种关系,而当它去解释人类的精神事件时,又用了后一种关系.在这个地方,罗尔斯顿的理论陷入了二元论。     

农户参与三氯杀螨醇替代技术培训积极性的影响因素分析

病虫害综合防治（1PM）技术旨在结合生物、农学及物理防治方法,合理使用化学农药,降低农业生产成本,保护农业劳动者健康和生态环境.以联合国开发计划署（UNDP）、环境保护部对外合作中心和全国农业技术推广中心联合启动实施的“中国含滴滴涕三氯杀螨醇生产控制及IPM技术替代全额示范项目”为例,系统分析影响农户参与IPM培训积极性的主要因素.结果表明,农户种植规模对农户参与IPM培训的积极性影响显著,学员性别和年龄不是影响其参加培训积极性的显著因素;学员参加培训的次数越多,其对IPM技术的采纳率越高.农民田间学校应更多地吸收老人和妇女参加三氯杀螨醇替代技术及IPM培训     

Sustainable tourism for remote atolls in the Pacific

SUMMARY

Coral atolls, as visitor destinations, have received little attention in the literature of tourism on mid-oceanic islands. However, the current trend of nature-based tourism, which involves travelling to relatively remote and undisturbed places, makes the atolls a desirable destination. This paper explores ways of how appropriate tourism can be introduced to atoll society within the context of traditional resource uses and the application of intermediate technologies. With the acceptance of a code of ethics for tourist behaviour and technologies aimed at reducing dependency of foreign imports, atoll tourism could become a viable economic alternative to the continued over-exploitation of marine resources.     

华北高产粮区桓台县农民地下水污染防治意愿的调查分析

桓台县是华北平原的具有代表性的高产粮区,长期集约化的农业耕作模式,导致地下水硝态氮含量的大幅上升,威胁当地居民的身体健康。为更好地保护地下水,降低农业生产对地下水的污染,在2007年春季对桓台县323位农民进行了地下水保护意愿调查,分别对农民农业生产环保意识、改善地下水污染的意愿和农民的环境保护责任意识进行了分析,结果显示多数农民担心地下水污染会对人体造成伤害,但是仅少数的农民了解不合理的农业耕作会导致地下水的污染;大多数农民乐意接受新型环保肥料,但是接近一半的农民表示当地缺乏农技人员的指导;多数农民表示愿意加入农业生产协会以改善农业生产方式,但是农民对于农业所造成的地下水污染责任意识不强;受教育程度和收入状况越高的农民地下水保护意识越强,越容易接受改善农业生产模式,责任心相对也较强。建议在桓台县加大对地下水污染防治的宣传和投入力度的同时,加强农业技术推广体系建设和健全地下水水质监控与监管体系等措施。

Establishing moral bearings: ethics and expatriate health care professionals in humanitarian work

Expatriate health care professionals frequently participate in international responses to natural disasters and humanitarian emergencies. This field of practice presents important clinical, logistical and ethical challenges for clinicians. This paper considers the ethics of health care practice in humanitarian contexts. It examines features that contribute to forming the moral landscape of humanitarian work, and discusses normative guidelines and approaches that are relevant for this work. These tools and frameworks provide important ethics resources for humanitarian settings. Finally, it elaborates a set of questions that can aid health care professionals as they analyse ethical issues that they experience in the field. The proposed process can assist clinicians as they seek to establish their moral bearings in situations of ethical complexity and uncertainty. Identifying and developing ethics resources and vocabulary for clinical practice in humanitarian work will help health care professionals provide ethically sound care to patients and communities.     

The Harm Principle and Genetically Modified Food

It is suggested that the Harm Principle can be viewedas the moral basis on which genetically modified (GM) food iscurrently regulated. It is then argued (a) that the concept ofharm cannot be specified in such a manner as to render the HarmPrinciple a plausible political principle, so this principlecannot be used to justify existing regulation; and (b) that evenif the Harm Principle were a plausible political principle, itcould not be used alone in the regulation of GM food, since itdoes not express a concern for the expected benefits of suchfood.
