The Murray–Darling Basin incorporates Australia’s three longest rivers and spans four states and one territory. It is important for an agricultural industry worth more than AUS$9 billion per year, but is also the life source and the spirit of the Indigenous Yorta Yorta people. Here, we address whether the interests of the Yorta Yorta people can encompass the common interest of the wider community in the Basin, and how the colonial legacy and climate change of the past century continue to influence the realization of the common interest moving forward. We find that shared regional governance with an agreed outcome supports the ongoing sustainability of the country and its people, but because of the legal history of Australia since colonization, recognition and mutual respect are no less important. Further, we note that the increasing climatic variability and changing climatic mechanisms that now exemplify the southeast of Australia corroborates the need for adaptive planning with longer time horizons. These lessons are supported by the customary law and practice of the Yorta Yorta people.  相似文献

Informal institutions have grown in relevance for the analysis of new ‘third wave’ democracies. The research strategy receives its impetus from the debate on neo‐institutionalism theory, which offers a productive perspective for structuring the field of analysis. This article explains the distinguishing factors between formal and informal institutions. It addresses five basic types of informal institutions, examines the ways in which they function and discusses their relevance in terms of democracy theory. Each type is characterized by the way in which it enacts its respective means of political influence. The study distinguishes between forms of specific relationship (clientelism), of material exchange (corruption), of violent exertion of influence (putsch threat), of civil resistance (civil disobedience) and of legal practice (custom law), and discusses their relevance to democracy. The central argument maintains that a differentiated study of informal institutions is crucial to addressing this question. The necessary typological differentiation allows us to make an appropriate assessment ‐one that does not manifest itself in a simple clear‐cut choice of affirmative or negative answers.  相似文献

The identification of fired bullets and spent cartridge cases is one of the key tasks of forensic science. The traditional comparison of signatures on specimen with a large collection with only a microscope is a very tedious and time-consuming work. Fortunately, electronic systems for performing a pre-selection have been invented since the last 25 years. On the basis of an expansive database the electronic comparison system used by the BKA, Germany, is evaluated and a mathematical value is proposed to rate the correlation quality. This effectiveness criterion can be valuable to give an objective assessment of different electronic comparison systems. Additionally, the applicability of the system on different calibres and land engraved area (LEA) width is discussed. The so called scores are also on disposition and their benefit to a decision-making is debated.  相似文献

This article draws conclusions based on an analysis of the relationship between economic ideas and institutional change in Soviet and post-Soviet Russia, so far covering roughly the years from 1971 to 2007. It analyses the recent debate on economic modernisation in Russian economics. We argue that the relative failure of transition has to be seen in the context of a ‘failed transition of the mind’ and that the recent modernisation debate resembles the debate of the Brezhnev period.  相似文献

Compared to morphine and morphine-6-glucuronide (M6G), codeine and its other major metabolites codeine-6-glucuronide and norcodeine have weak affinity to opioid μ-receptors. Analgesic effects of codeine are thus largely dependent on metabolic conversion to morphine by the polymorphic cytochrome P450 isoenzyme 2D6 (CYP2D6). How this relates to toxicity and post-mortem whole blood levels is not known. This paper presents a case series of codeine-related deaths where concentrations of morphine, M6G and morphine-3-glucuronide (M3G), as well as CYP2D6 genotype, are taken into account. Post-mortem toxicological specimens from a total of 1444 consecutive forensic autopsy cases in Central Norway were analyzed. Among these, 111 cases with detectable amounts of codeine in femoral blood were identified, of which 34 had femoral blood concentrations exceeding the TIAFT toxicity threshold of 0.3mg/L. Autopsy records of these 34 cases were retrieved and reviewed. In the 34 reviewed cases, there was a large variability in individual morphine to codeine concentration ratios (M/C ratios), and morphine levels could not be predicted from codeine concentrations, even when CYP2D6 genotype was known. 13 cases had codeine concentrations exceeding the TIAFT threshold for possibly lethal serum concentrations (1.6 mg/L). Among these, 8 individuals had morphine concentrations below the toxic threshold according to TIAFT (0.15 mg/L). In one case, morphine as well as M6G and M3G concentrations were below the limit of detection. A comprehensive investigation of codeine-related fatalities should, in addition to a detailed case history, include quantification of morphine and morphine metabolites. CYP2D6 genotyping may be of interest in cases with unexpectedly high or low M/C ratios.  相似文献
