发达国家城市环境治理的若干经验

发达国家城市环境治理的经验主要有:完善环境保护法律制度,保证治理措施的有效实施;健全环境管理体系,强化环境行政管理;注意推动自愿性行动来保护环境,积极推动公众参与环境治理;运用经济手段,制定激励奖惩措施,提高环境治理的效率;合理划分环境治理权限,建立权威性的管理机构;大量发展环境教育,通过民众环境保护意识,形成民族心理;加大科技投入,注重科技进步,发展环保产业。这些经验及其教训留给人们诸多启示,值得中国学习与借鉴。     

红色旅游对游客国家认同的影响

红色旅游作为传承红色基因、加强爱国主义教育、增强国家认同的有效载体,具有鲜明的政治功能。以认知评价情绪评价理论和积极情绪拓展—建构理论为基础,构建红色旅游国家认同影响模型并提出相应假设,运用偏最小二乘法结构方程模型（PLS-SEM）进行了实证检验。结果显示：构建的红色旅游国家认同影响模型具有良好的解释力和预测力,模型具有交叉效度,整体模型的GOF值高于良好适配度的标准值;红色旅游通过红色旅游情感对游客国家认同有正向促进作用;历史认同对国家认同的影响不明显,其他假设均成立。该研究为相关模型构建提供了思路,成果可为强化红色旅游的国家认同研究、拓展红色旅游理论内涵与教育功能、促进红色旅游高质量发展提供理论依据。

Prior encounters with the opposite sex affect male and female mating behavior in a wolf spider (Araneae,Lycosidae)

Mate availability can vary widely in nature depending upon population density and sex ratio and can affect the ability of individuals to be selective in mate choice. We tested the effects of prior encounters with the opposite sex (i.e., exposure to the opposite sex either with or without mating) on subsequent mating behavior in two experiments that manipulated mate availability for both males and females in the wolf spider, Hogna helluo. The probability of mating in the experimental trial depended upon whether the prior encounter involved mating or not, and males and females responded in opposite directions. Exposure without mating resulted in a higher subsequent frequency of mating for females and a lower subsequent frequency of mating for males, while prior mating experience resulted in a lower frequency of female remating and a higher frequency of male remating. Prior exposure without mating did not affect female aggression. However, mated females engaged in precopulatory cannibalism more frequently than virgins. Mated males escaped postcopulatory cannibalism more frequently than virgins. Our results show that males respond to exposure without mating in the expected manner. However, prior mating (1 week earlier) had unexpected effects on males, which may be due to mated males being of higher quality. There were little or no effects of the size of the prior exposure individual or mate on subsequent mating behaviors. Further research is needed to determine why different species use different degrees of prior information in mate choice.     

中国台湾地区土壤及地下水污染整治管理与经验

中国台湾地区土壤及地下水污染整治基金管理会自2001年成立以来,不断完善管理架构和管理体系,发布相关领域的法律法规、行政规则和公告,有效运行污染整治基金的财务筹措和使用等经济管理机制。开展了一系列行之有效的预防、监测、调查、评估等管理工作,为污染场地的识别和筛选奠定了坚实的基础。对于污染场地的整治工作,采用标准和风险评估相结合的验收方式,推行场地可持续利用的绿色修复技术。重点研究台湾地区土壤及地下水污染整治工作的管理政策、模式和措施,总结相关经验,为中国土壤及地下水污染防治工作提供借鉴和参考。     

发达国家（地区）农业现代化进程中农户与市场对接模式比较

通过对美国、日本、法国、我国台湾地区农户与市场对接模式的比较,发现依靠中间组织——农协、企业、农业合作组织等实现了农业流通现代化。基于此,结合我国农业现状和具体国情,提出从政府引导、农产品流通的组织建设、加强市场监管力度三个方面来实施我国农户与市场的对接,从而加快我国农业流通现代化进程和农业经济的可持续发展。

基于经验权重方法的舟曲县泥石流易发性评估

舟曲县泥石流灾害频发,2010年8月发生的特大山洪泥石流,造成大量生命财产损失。文章采用遥感影像结合地面调查获取舟曲县植被覆盖、岩性、构造等信息;基于数字高程模型与水文分析获取水系、沟谷纵比降、沟谷弯曲度、流域、坡度信息;基于国土资源部在全国开展县市灾害调查中提供的泥石流易发性量化经验权重,对全县178条较大沟谷进行泥石流易发性评价。得到的结果与野外考察和前人认识具有较高的一致性。该方法不需要大量的野外工作,具有评估迅速简单的特点,对县级以上区域尺度的泥石流易发性快速评估具有较高推广价值。     

An evaluation of a shared experience group for women and their support persons following prenatal diagnosis and termination for a fetal abnormality

Objectives Support after fetal diagnosis of abnormality (SAFDA), is a facilitated shared experience group for women and their partners or support person, in Victoria, Australia, who have had a pregnancy termination for a fetal abnormality. The objective of this study was to evaluate the SAFDA-facilitated group. Methods A questionnaire-based study was undertaken between 2001 and 2005 to evaluate SAFDA. A deidentified self-completed questionnaire was given to participants at the end of each group and included questions relating to the referring professional, participants' prior expectations of the group, helpfulness of participation, preferred group format, length, and venue. In addition, there was also opportunity for participants to make general comments on their experiences of participating in SAFDA. Results A total of 85 participants (100% response) completed the questionnaire. Seventy-one participants (84%) considered it ‘very helpful’ to participate in the group. Seventy-eight participants (92%) considered that a shared-experience group was the most beneficial format. Comments written by participants affirmed that the present format of SAFDA was a highly valued opportunity to listen to and share experiences in a confidential small group. Conclusion SAFDA is a beneficial forum for women and their partners or support person to share their experiences after having had a pregnancy termination for a fetal abnormality. Further, SAFDA provides information and insights for health professionals who are considering how best to support women. Copyright © 2007 John Wiley & Sons, Ltd.
