International Cooperation and Coordination on Prevention and Control of the Environmental Damage Caused by Ship＇s Ballast Water

船舶压载水在提高船舶安全性的同时也给海洋环境带来了严重的甚至永久性的损害。而海洋环境的有机统一性和船舶世界航行的特点，决定了国际社会只有通过广泛的合作与协调，才能防控船舶压载水造成的海洋环境损害。本文论证了防控船舶压载水造成海洋环境损害国际合作与协调的必要性和路径选择，进一步研究了实现上述合作与协调的相应机制，为我国应对防控船舶压载水造成海洋环境损害的国际合作与协调趋势提出了建议。     

加大改革力度 缓解水资源危机—关于缓解吉林省水资源短缺状况的几点建议

2000年,吉林省遭受了有气象记录以来的罕见旱灾,致使城乡经济蒙受巨大损失。从根本上改变这一状况,政府责无旁贷。在市场经济条件下,政府应在管水用水治水方面加大改革力度,实现水资源的合理配置。国内外实践表明,对城乡防洪、排涝、蓄水、用水、节水、污水处理及回用等涉水事宜进行统一管理,是符合经济社会发展要求的,也有益于经济社会的可持续发展。

Egypt versus Ethiopia: The Conflict over the Nile Metastasizes

Egypt and Ethiopia continue to oppose one another over the allocation of the waters of the Nile River basin, despite a succession of provisional multilateral agreements. Officials in Cairo insist that Egypt be guaranteed its “historic rights” to two-thirds of the river’s flow, while their counterparts in Addis Ababa demand an “equitable” distribution of water among all of the riparian countries. More important, Sudan’s shift in alignment from Egypt to Ethiopia has injected new tension into the dispute, and the sustained involvement of South Sudan, Kenya, Uganda and Eritrea heightens the likelihood that periodic crises will escalate into armed confrontations. Consequently, existing studies that offer sanguine assessments of the potential for a compromise settlement fail to address the key dynamics that drive the conflict.     

Exploring the Relationship between Operational and Financial Indicators: The Case of Water and Sewer Utilities

ABSTRACT

There is debate in the literature on whether or not general management principles are applicable to the study and practice of public administration. This research responds by exploring how local officials manage the performance of public services with private good characteristics, where general management principles could be embraced for service delivery. The relationship between operational and financial indicators is explored within the functional areas of water and sewer, with the hypothesis that operational outcomes impact financial outcomes similar to private enterprises. Because the findings do not support this hypothesis, the authors conclude that general management principles may not be applicable to all forms of administration given that public cannot be removed from the management of public services even with private good characteristics.     

东北地区水资源一体化管理研究

水资源一体化管理是东北地区区域整合的基础之一,也是节水型社会建设的根本要求。东北地区的水资源一体化管理虽有"松辽管理模式"等的发展基础,但在体制与机制、水市场建设、水资源安全等方面仍存在许多问题。借助国内外水资源管理的理论成果,认为东北地区的水资源一体化管理应该主要理顺管理体制和运行机制、进一步完善安全系统、加快水市场建设步伐、协调好区域水资源配置、加快全区域节水型社会建设。     

论水权的优先权

水权优先权具有重要功能 ,是我国水权制度和水市场建立的重要一环。在水权取得方面主要有河岸权原则、先占用原则和所有权绝对原则 ,而在水权优先位序规则的确立上 ,各国因具体情况不同 ,采取的方案也不尽相同。我国在遵循水资源的可持续利用、兼顾公平与效率及遵从习惯、因地制宜三大原则的前提下 ,应确立先占用原则为主的水权取得优先权原则 ,同时承认习惯水权 ,进而构建符合我国实际情况的水权优先位序规则。     

论环境行政指导在水资源保护中的运用

水是人类赖以生存的物质基础 ,水资源的可持续利用是关系到人类生存和发展的大事。环境行政指导在我国的水资源保护中起着不可替代的作用。

Spatial Distributions of Oxygen Stable Isotope Ratios in Tap Water From Mexico for Region of Origin Predictions of Unidentified Border Crossers

One of the many difficulties associated with identifying undocumented border crossers stems from an inability to narrow down the search area for the region of origin and family members to obtain family reference samples for DNA comparison. While the geography of regions of origins is wide, the biological profiles of the undocumented border crossers often show strong similarities, young and male. The isotopic composition of human bones, teeth, and hair has been demonstrated to be useful biomarkers for tracing locations and movements of individuals and for aiding in the identification of human remains. Data obtained from human remains can be compared to and aligned with various reference sources, such as soils and bedrock, archaeological remains, or cultural data. Here, the spatial deficiency in isotopic reference data for Mexico, specifically for oxygen (δ¹⁸O) isotopes in tap water, is being addressed through the collection and analysis of over 150 water samples and explored with tooth enamel isotopic values from recently identified Mexican nationals. The isoscape was developed using a Spine with Barriers interpolation method and shows sufficient detail to narrow down the regions where specific isotopic values are represented. The individuals were plotted on the developed isoscape using conditional correlations. The methodology was successful in assigning the correct regions of origin for the two individuals, which shows the tremendous potential of the developed isoscape. Nonetheless, there is more research needed to further improve upon this geolocation method, including analysis of multiple isotopes in different tissues, and the development of new isotopic methods.
