The 2008 energy crisis raises questions with regard to Saudi Arabia's status in the global oil market in general and within the Organisation of Petroleum Exporting Countries (OPEC) in particular. Over time, several circumstances such as disagreement amongst OPEC members, the challenge of the alternative energy industry, and the growing influence of petro-traders have restricted Saudi Arabia's influence on the oil market in general and within OPEC in particular. This commentary adds another dimension to the analysis of Saudi Arabia's status in the oil market, by defining the relations between Saudi Arabia and two leading and important oil exporters unaffiliated to any petroleum organisations: Russia and Norway. 相似文献

This article offers a discussion of the probable effects of a Worldwide Patent System for developing countries. It draws upon insights from the ongoing processes in the World Intellectual Property Organization and elsewhere relevant for the global patent system and discusses these features from a developing country perspective. For scientifically advanced developing countries the effect in their most advanced and most global enterprises is potentially positive as they will benefit as much as other multinational companies. In areas of research and development where these most advanced developing countries do not possess a high level of technological capacity, a Worldwide Patent System is unlikely to create any benefits for them. For countries with the ability to copy and produce inventions made by others a Worldwide Patent System will have a negative effect as inventors will have little opportunity to utilise the system, whereas they will be bound by a larger number of exclusive rights narrowing down their space for innovation. For the least developed countries an additional problem arises: it might become even more difficult to import essential goods because patents will be in force in these countries even though there is no production of that product in the country. 相似文献

Between 1907–1916, Lenin developed a programme for the capitalist development of the Russian countryside which was intended 1) to prepare the material and social foundations for socialism, and 2) to provide an alternative to the tsarist regime's pro‐capitalist efforts. During this period, he hoped for a Marxist‐led bourgeois revolution. In his view, a petty bourgeois peasantry inspired by archaic fantasies of social justice and a realistic hatred of gentry privilege and liberal compromise, were crucial to any Marxist success. 相似文献

This paper presents a way of thinking about how to respond to the pluralism of modern societies that avoids any commitment to contractualist norms of political justification. The argument developed appeals to the notion of a constitutional settlement. Constitutional settlements are complex on-going social practices that both express certain values to which political societies are committed and establish procedures for resolving disputes among members of these societies. As such, they are a product of both moral commitment and the balance of power. The paper shows how constitutional settlements relate to issues of stability and non-subjugation in politics, and explains how they can ground a distinction between justice and legitimacy. 相似文献

Hair analysis has shown great potential in the detection and control of drug use. Whether an assay is of quantitative value roughly corresponding to the amount of drug consumed, is still a matter of debate. The present investigation was aimed at a possible relationship between the cannabinoid concentration in hair and the cumulative dose in regular users of cannabis. Hair samples from the vertex region of the scalp were obtained from 12 male regular users of cannabis, and 10 male subjects with no experience of cannabis served as controls. None of the subjects had his hair permed, bleached or colored. Cannabis users provided information on drug use such as the current cannabis dose per day, the cumulative cannabis dose of the last 3 months, as well as the frequency of cannabis use during the last year. The concentration of delta-9-tetrahydrocannabinol (THC), cannabinol (CBN) and cannabidiol (CBD) in hair was determined using gas chromatography-mass spectrometry. Cannabinoids were present in any hair sample of cannabis users, but were not detectable in control specimens. An increase in the amount of cannabinoids in hair with increasing dose was evident. The concentration of major cannabinoids (sum of THC, CBD and CBN) was significantly correlated to either the reported cumulative cannabis dose during the last 3 months or to the cannabis use during the last 3 months estimated from the daily dose and the frequency per year (r=0.68 or 0.71, p=0.023 or 0.014). A significant relationship between THC and the amount of cannabis used could not be established. As a conclusion, the sum of major cannabinoids in hair of regular users may provide a better measure of drug use than THC. 相似文献

Many species of insects are able to fly at night or in very low light intensities. The question of whether calliphorid blowflies are also able to do this to locate a corpse and oviposit nocturnally is of considerable forensic importance. However, to date studies of this behaviour have been contradictory. Here, the activity and number of Calliphora vomitoria L. and Lucilia sericata (Meigen) (Diptera: Calliphoridae) caught on sticky-traps were examined in a slow-speed wind tunnel, at different intensities of artificial light. The traps were either unbaited or baited-with liver. The number of both species caught, decreased incrementally as light intensity was reduced. While the responses of the two species were broadly similar, L. sericata were significantly more active than C. vomitoria, especially at higher light intensities. The number of flies of both species that were caught was higher in the presence of liver bait, but the presence of the liver bait did not change the shape of the relationship between catch and light intensity. Hence, light intensity acts as an independent exogenous stimulus for activity and although liver volatiles increase activity levels, they are not necessary as an activation stimulus. Comparison of the numbers caught in small or large enclosures suggests that any flies caught in darkness probably alighted on the trap by chance and that in darkness, while flies may be activated by carrion odours, they do not appear to be able to navigate effectively to the source of that odour. The results presented here suggest that in darkness, the probability of oriented flight leading to oviposition on a corpse by either species, is relatively low. 相似文献
