试论我国地下水资源的法律保护

我国地下水的开发存在过量开采、无序开采等问题,并进而引发了一系列的环境地质灾害。要保护地下水资源必须建立市场化的水权流转交易机制及建立健全相关制度,推动循环经济下的水资源保护,改革水资源管理体制,强化环境行政执法。     

论西汉关中平原的水运交通

为了充实都城所在关中地区的经济实力,西汉政府特别重视漕运交通的建设。首先整治利用了前人开辟的渭汧两大自然河流的水路联运道路;其次在汉武帝元光六年(前129)于渭水南岸开凿了东西三百余里的漕渠,大为成功。不久又兴修了褒斜道漕渠线路,惜因自然原因无法通漕。在关中内部渭河北岸,也有连接洛渭两水之人工运河的修凿,它沟通了都城长安与邑漕仓的联系,作用巨大。自然河流与人工运河的相互沟通与漕运,使西汉关中的水运交通发展到其古代历史上的最高峰。     

绿洲农业开发风险分析研究进展

西部大开发中,绿洲农业综合开发成为热点。由于绿洲环境的特殊性,在农业开发建设中必然面临更多不确定性的风险,从而影响绿洲的可持续发展。该文在介绍绿洲概念和生态特征的基础上,从水资源可持续性风险分析（分为水资源承载力评价、水资源可持续性评价和生态脆弱性评价三个部分）、生态环境可持续性评价（主要是防护林评价）和社会经济可持续性评价三个方面展开,介绍了绿洲农业综合开发和社区建设中遇到的主要风险（生态风险中的水资源风险和防护林风险）、移民管理风险及投资风险的理论和评价方法,为绿洲风险的评价研究提供了一个全面的基础资料介绍。     

城镇水资源市场再造流程

传统的城镇水价制定机制扭曲了资源利用的激励机制,对其进行再造是必要的.城镇水市场再造包括水资源产权的建立与管理,水交易市场的建立与管理,水排污市场的建立与管理以及执法队伍及管理人员才能的培育及管理等.同时,对水市场的再造提出了一个建议性的流程.

Clinical management of gender dysphoria in children and adolescents: the Dutch approach

The Dutch approach on clinical management of both prepubertal children under the age of 12 and adolescents starting at age 12 with gender dysphoria, starts with a thorough assessment of any vulnerable aspects of the youth's functioning or circumstances and, when necessary, appropriate intervention. In children with gender dysphoria only, the general recommendation is watchful waiting and carefully observing how gender dysphoria develops in the first stages of puberty. Gender dysphoric adolescents can be considered eligible for puberty suppression and subsequent cross-sex hormones when they reach the age of 16 years. Currently, withholding physical medical interventions in these cases seems more harmful to wellbeing in both adolescence and adulthood when compared to cases where physical medical interventions were provided.     

A developmental, biopsychosocial model for the treatment of children with gender identity disorder

This article provides a summary of the therapeutic model and approach used in the Gender Identity Service at the Centre for Addiction and Mental Health in Toronto. The authors describe their assessment protocol, describe their current multifactorial case formulation model, including a strong emphasis on developmental factors, and provide clinical examples of how the model is used in the treatment.     

The dynamic development of gender variability

We diagram and discuss theories of gender identity development espoused by the clinical groups represented in this special issue. We contend that theories of origin relate importantly to clinical practice, and argue that the existing clinical theories are under-developed. Therefore, we develop a dynamic systems framework for gender identity development. Specifically, we suggest that critical aspects of presymbolic gender embodiment occur during infancy as part of the synchronous interplay of caregiver-infant dyads. By 18 months, a transition to symbolic representation and the beginning of an internalization of a sense of gender can be detected and consolidation is quite evident by 3 years of age. We conclude by suggesting empirical studies that could expand and test this framework. With the belief that better, more explicit developmental theory can improve clinical practice, we urge that clinicians take a dynamic developmental view of gender identity formation into account.     

Thoughts on the nature of identity: how disorders of sex development inform clinical research about gender identity disorders

Disorders of sex development (DSD), like gender dysphoria, are conditions with major effects on child sexuality and identity, as well as sexual orientation. Each may in some cases lead to change of gender from that assigned neonatally. These similarities-and the conditions' differences-provide a context for reviewing the articles in this issue about clinical approaches to children with gender dysphoria, in relation to assessment, intervention, and ethics.
