This paper studies the impact of daily official foreign exchange interventions on the exchange rates in Croatia for the period from 1996 to 2004. Using the event study methodology and a variety of GARCH models reveals that the Croatian central bank was in a position to influence, to some extent, the level of the exchange rate during the period studied. This lends support to the view that foreign exchange intervention may be effective in emerging market economies. 相似文献

An analytical method using solid-phase extraction (SPE) and high-performance liquid chromatography–mass spectrometry (LC–MS) has been developed and validated for the confirmation of Δ9-tetrahydrocannabinol (THC) in oral fluid samples. Oral fluid was extracted using Bond Elut LRC-Certify solid-phase extraction columns (10 cm3, 300 mg) and elution performed with n-hexane/ethyl acetate. Quantitation made use of the selected ion-recording mode (SIR) using the most abundant characteristic ion [THC + H+], m/z 315.31 and the fragment ion, m/z 193.13 for confirmation, and m/z 318.00 for the protonated internal standard, [d3-THC + H+]. The method proved to be precise for THC, in terms of both intra-day and inter-day analyses, with coefficients of variation less than 10%, and the calculated extraction efficiencies for THC ranged from 76 to 83%. Calibration standards spiked with THC between 2 and 100 ng/mL showed a linear relationship (r2 = 0.999). The method presented was applied to the oral fluid samples taken from the volunteers during the largest music event in Portugal, named Rock in Rio-Lisboa. Oral fluid was collected from 40 persons by expectoration and with Salivette®. In 55% of the samples obtained by expectorating, THC was detected with concentration ranges from 1033 to 6552 ng/mL and in 45% of cases THC was detected at concentrations between 51 and 937 ng/mL. However, using Salivette® collection, 26 of the 40 cases had an undetectable THC. 相似文献

This article explores the development of inter-American Catholicism during the 1950s and 1960s. It analyses the role of the Chilean Catholic bishop Manuel Larraín (1900–1966) in his efforts to disseminate his diagnosis of underdevelopment in Latin America and to establish links with the Catholic world in the United States. Based on a review of his writings, the American press and documentation from Catholic organisations, it is suggested that the Chilean bishop advocated the implementation of social reforms and American collaboration to prevent the advance of communism and strengthen Catholicism on the continent. 相似文献

The authors compared the effects of alcoholic drinks rich in fusel oil with the effects of diluted pure alcohol of the same quantity on 19 clinically healthy university students. The investigations utilized EEG and physiopsychic testing methods. The clinical symptoms were observed both under the effect of drinks and in a crapulous state ("hang-over"). It was found that alcoholic drinks rich in fusel oil can produce a more deviating EEG curve, an increased worsening of physiopsychic performance and of clinical and subjective symptoms. The necessity of regular quality control of alcoholic beverages is pointed out. 相似文献

In comparative analysis of welfare states, there is a consensus that mature welfare state systems have been confronted, for some considerable time, with substantial pressure towards re-structuring and that, as a result, they actually have undertaken several and varied modifications. This articles aims at exploring and analysing these developments in Austria and Germany from a comparative point of view. The analysis concentrates on two vital fields of social policy: old-age insurance and unemployment insurance. Especially in respect of the development of social policy and regarding important characteristics of the two welfare state systems, both countries traditionally show a large degree of resemblance to each other. Many similarities remained to exist during the phase of growing pressures on the welfare state, whereas at the same time it is evident that differences between the two countries increased. The respective actual developments will be interpreted in the light of corresponding theories of comparative welfare state research and classified as gradual and structural changes. 相似文献
