This paper describes the gross domestic product and hydrological environment service method for assessing the socio-economic consequences of implementing necessary measures for safeguarding the quality of groundwater for human consumption and eliminating the risk of pollution. This method assesses the positive and negative impacts of designations of protected areas. Economic assets and social goods are the two integrated variables used in analysing the method. The first includes economic impacts on the local gross domestic product of defining protected areas, and the second considers the benefits of this designation in the conservation of water resources, assigning a monetary value to the preserved resources. In addition, tools have been incorporated, such as payment for hydrological services and generation of permissible activities, which reduce negative social impacts through positive economic impacts. These tools can only be used when compliance with conservation requirements for protected areas is demonstrated. The conclusions of this study include an application of the proposed methodology and provide essential and specific assessments that show that this methodology fulfils the requirements of the European Water Framework Directive requirements and that it is an effective tool in the implementation and development of strategies for hydrological planning processes. 相似文献

Why do laws become similar across countries? Is the adoption of similar laws and policies due to factors operating independently within each country? Do countries develop similar rules in response to similar challenges? Or is the similarity of laws and policies due to the interdependent responses that scholars have referred to as processes of policy convergence, transfer, and diffusion? We draw on an analysis of immigration and nationality laws of 22 countries throughout the Western Hemisphere from 1790 to 2010, and of seven case studies of national and international policymaking, to show that policies are often interdependent, even in the domain of immigration law, which scholars have presumed to be relatively immune to external influence. We argue that specific mechanisms of diffusion explain the rise of racist immigration policies in the Americas, their subsequent decline, and the rise of an anti‐discriminatory norm for policies. Most striking among our findings is that at key junctures after 1940, weaker countries effectively advanced an anti‐discriminatory policy agenda against the desires of world powers. We identify the conditions under which weaker countries were able to reach their goals despite opposition from world powers. 相似文献

Challenging DNA: Assessment of a range of genotyping approaches for highly degraded forensic samples
M. Fondevila N. Naverán M. Cerezo A. Rodríguez R. Calvo L.M. Fernández Á. Carracedo M.V. Lareu 《Forensic Science International: Genetics Supplement Series》2008,1(1):26-28
It is common in forensic casework to encounter highly degraded DNA samples from a variety of sources. In this category bone and teeth samples are often the principal source of evidential material for criminal investigations or identification of long-deceased individuals. In these circumstances standard STRs are prone to fail due to their long amplicon sizes (since DNA becomes progressively more fragmented as it degrades). To successfully resolve such cases alternative markers can be used and until recently the only other tool available was mitochondrial DNA, which despite being more resistant to degradation, is much less informative. A rapidly developing approach to analyzing degraded DNA is the typing of loci from short-amplicon PCR products based on markers such as mini-STRs and autosomal SNPs. We have performed an analysis of several cases with naturally degraded DNA using established STRs plus mini-STRs and autosomal SNPs in order to make an objective comparison of the performance of each method using challenging DNA. The main aim was to establish the benefits and drawbacks of each marker set to help the practitioner choose the DNA analysis method most suited to the circumstances of each case. 相似文献

The commissioners of human rights in the Parliament aim at ensuring the protection and formation as well as the development of the culture of human rights with their activities in Hungary and all over the world. What else could be done by the citizens practising their disobedience during the non-violent revolutions in 1989 after Mahatma Gandhi, Martin Luther King and the American Henry David Thoreau? At a first glance, it perhaps seems to be strange to put the following question: what is the connecting link between the role of political law of a public state and the citizens breaking the rules in order to protect the constitutional rights? What will be the result of this comparison? I think, the result is that we can recognize the role of both functions more thoroughly in operating the constitutional state suitably in order to protect the culture of constitutional rights (reactive role) and to develop them (proactive role). 相似文献

The principles of constitutional law as those of many other disciplines seem to develop and to be replaced by new paradigms in the light of globalization. The present article using the genre of constitutional futurology attempts to determine whether this change is real or an illusory impression, and to predict the future of constitutional law and of scholarship reflecting on constitutional issues. A mighty forecast emerges from the interplay of opposing forces. While the withering away of the constitutionalist paradigm is unlikely partly because of the lack of a new generation of legal scholars following new patterns of thinking, partly because there is no reason to assume that the prevalent socioeconomic order would cease to exist , the essay maps a number of possible challenges like genetic engineering or personal computers interconnected in the World Wide Web , which constitutionalists shall expect to face in theory and in practice alike. 相似文献

The duty-of-care requirement cannot be used anymore as the touchstone to differentiate negligence from strict liability because
it can be found in many forms of the latter. Duty of care is smuggled into strict liability hidden under the scope of liability
requirement (traditionally called “proximate causation”). As far as the scope of liability requirement is common to negligence
and to many forms of strict liability, there is a fairly large common ground to both liability rules, and consequently the
marginal Hand formula is applied to both rules. Indeed, under a negligence rule, the marginal Hand formula is applied twice:
first to assess whether or not the defendant did breach his or her duty of care, and, second, to delimit whether or not the
defendant’s behavior was a proximate cause of the harm suffered by the victim. However, under a strict liability rule, the
Hand formula is applied only once when the proximate causation question is raised. Traditional law and economics analysis
has almost always taken the normative question raised by the causation requirement as given, which is a potential major problem
due to the importance of scope of liability or proximate causation in legal practice. Defining the scope of liability, that
is to say, the boundaries of the pool of potential defendants, is the basic legal policy decision for each and every liability
rule. In the normative model presented in this paper, the government first chooses efficient scope of liability, and given
the scope of liability, the government then decides the liability rule and damages that guarantee efficient precaution. In
the article, most known scope of liability rationales developed by both common law and civil law systems are discussed in
order to show the substantial common ground between negligence and strict liability. 相似文献
