Governing sexual behaviour through humanitarian codes of conduct

Since 2001, there has been a growing consensus that sexual exploitation and abuse of intended beneficiaries by humanitarian workers is a real and widespread problem that requires governance. Codes of conduct have been promoted as a key mechanism for governing the sexual behaviour of humanitarian workers and, ultimately, preventing sexual exploitation and abuse (PSEA). This article presents a systematic study of PSEA codes of conduct adopted by humanitarian non‐governmental organisations (NGOs) and how they govern the sexual behaviour of humanitarian workers. It draws on Foucault's analytics of governance and speech act theory to examine the findings of a survey of references to codes of conduct made on the websites of 100 humanitarian NGOs, and to analyse some features of the organisation‐specific PSEA codes identified.     

流域开发的外部性及其内部化

流域是地表水的集水区域。流域问题的本质是水。水是可持续发展的基础和条件，是环境与发展问题的核心。流域开发是以水资源为先导和主体的综合资源开发。实现流域经济可持续发展实质就是实现流域水资源可持续开发和利用。外部性是流域开发的基本特征，水资源的特性决定了流域开发的外部性。实现流域开发的外部性内部化是流域经济可持续发展的关键。实现流域开发外部性内部化，必须界定流域资源产权，明确流域开发主体；建立税收－补贴体系，对水资源合理定价；坚持“排污者付费原则”；建立流域水资源市场，实现水资源资产化管理。同时，政府要加强流域的管理；建立健全水资源保护与流域开发的法律体系；普及保护环境和水资源的教育，建立节水观念；支持和鼓励流域开发企业实行外部成本内部化措施；调整产业结构，深化国有企业改革。     

The relationship between sustainable development and resource use from a geographic perspective

Geography provides the basic building blocks for the study of resource use and sustainable development, inasmuch as it categorizes the human environment. Within the environment are resources that are needed for the survival of society. As resources are largely limited and finite, humans as agents of change must employ techniques that allow an efficient and lasting use of the available resources in their environment. This paper discusses the nexus between geography, resource exploitation, use, and sustainable development. It also discusses the characteristics, types, and classification of resources, development and sustainable development as well as the challenges and strategies for attaining sustainable development, particularly in developing countries.

基于整体开发管理的国际河流决策支持系统

基于国际河流开发管理的现状，分析国际河流整体开发管理理论的演进。得出整体开发管理决策实施的原则及思路：流域开发管理要以流域边界为界，将整个水系自然联系的区域作为不可分割的整体，进行统一权衡，突出共同利益，流域内开发与流域外开发相结合。以建立多层次的国际合作机构。对国际河流决策支持系统进行设计，即以国际河流流域为体系，各国国内流域测点为单元。国际流域综合协调委员会为决策支持中心、各国流域机构委员会为决策支持分中心。并研究系统的公用信息平台建设，信息开发、管理与维护。河流水资源、水环境实时监控等技术支持系统。实证分析澜沧江-湄公河流域决策支持系统的建设。并指出国际河流水资源的开发与管理，水权等问题有待进一步深入研究。

The functional significance of infanticide in a population of California ground squirrels (Spermophilus beecheyi)

Naturally-occurring infanticide was observed in a population of California ground squirrels (Spermophilus beecheyi). In four seasons, 40 infanticides were observed. All victims were post-emergent pups. Of 37 killings in which the killer was sexed 36 were by females. All infanticidal females were mothers at the time they killed, but in no case was a mother seen to kill or harm her own young. The victim was cannibalized in 22 cases and taken immediately into the killer’s burrow in 16 others. In no case did killers gain access to the victimized mother’s burrow or territory and female pups were not killed preferentially over males. In light of evolutionary explanations, infanticide in this population may best fit the resource exploitation hypothesis, in which killers commit infanticide to gain a nutritional benefit. Resource competition is a possible auxiliary explanation, since any time a female kills unrelated young she is eliminating possible competitors to her own offspring. This behavior could confer a fitness advantage on killers or it could be an adaptively neutral, alternative feeding strategy. More data are necessary to distinguish between these hypotheses.

浅论新疆资源的开发与环境保护

开发西部地区已经成为我国一项跨世纪的战略任务,搞好西部地区的生态环境保护是西部大开发的首要任务。新疆地处祖国西北边陲,其国土面积、资源储备和战略地位都在西部开发中占有重要地位。本文针对长期以来新疆在开发自然资源、发展经济的同时产生的环境问题,提出了建议和对策。     

南岭山区传统聚落景观资源及其旅游开发研究

南岭山区的乡村传统聚落,经特定历史地理环境的演进和发展,以其特有的景观美学价值、鲜明的地域文化特色和科学实用价值的完美结合,而成为极为珍贵的历史文化遗产。由于古代南岭山区复杂地理环境的隔绝机制和移民们一直恪守着祖宗留下的遗风,其聚落景观至今得以大量保存而成为极富开发价值的 旅游资源。为促进南岭山区21世纪社会经济的快速发展,应将这一丰富的旅游资源的开发利用和保护列入议事日程。但必须深入调查研究,并坚持突出重点,择优开发;因地制宜,突出地域文化特色;旅游开发与乡村社会经济发展协调;保护与利用并重等开发原则。
