Nowadays immunoassays are used for the rapid screening of drugs world-wide. Despite the fact that they are a highly valuable tool for the test of legal and illicit drugs, there is a non-negligible risk of false positive and false negative findings, and many pitfalls must be taken into account when using these tests in an uncritical manner and without valid confirmation procedures. In accordance with the committee for "problems of threshold values for medical and addictive drugs" set up by German scientific societies (in particular GTFCh, DGRM and DGVM), immunoassays are recommended as a useful tool for screening. But confirmation analysis with conclusive methods (GC/MS or LC/MS) is indispensable for valid substance identification, discrimination between active and inactive metabolites, detection of escort substances and accurate determination of concentrations in body fluids. 相似文献

The authenticity of recovered memories is a much debated issue. Surprisingly, no study has systematically looked at symptom overreporting in people claiming recovered memories of childhood sexual abuse (CSA). In a first sample we administered the Structured Inventory of Malingered Symptomatology (SIMS) to individuals who said they had recovered CSA memories (n=66), individuals who said their CSA had always been accessible (continuous CSA memory group; n=119), and controls who said they had no CSA experiences (n=83). In a second sample individuals reporting recovered (n=45) or continuous (n=45) CSA memories completed the Morel Emotional Numbing Test (MENT). Our aim was to compare these groups with regard to their tendency to overreport symptoms. The results indicate that people with recovered memories do not score higher on the SIMS and the MENT than other CSA survivors suggesting that symptom overreporting is not typical for people reporting recovered memories. 相似文献

The Council Regulation (EC) no. 1493/1999 of 17 May 1999 on the common organisation of the market in wine (Abl. L 179 dated 14/7/1999) and the GMO Wine 2000 (Annex VII A) stipulates that the labels of wine bottles have to indicate, among others, information on the sales designation of the product, the nominal volume and the alcoholic strength. The latter must not differ by more than 0.5% vol. from the alcoholic strength as established by analysis. Only when quality wines are stored in bottles for more than three years, the accepted tolerance limits are +/- 0.8% vol. The presented investigation results show that deviations have to be taken into account which may be highly relevant for forensic practice. 相似文献

This paper investigates the behavior of rent-seeking politicians in an environment of increasing economic integration. The focus of the paper is on the implications of globalization-induced political yardstick competition for constitutional design with a view to the current discussion in the European Union. In contrast to the established literature, we carefully portray the double-tiered government structure in federal systems. The number of lower-tier governments and the allocation of policy responsibilities to the two levels of government are subject to constitutional choice. 相似文献

Identification of DYS385 allele variants by using shorter amplicons and Northern Thai haplotype data
Primers currently used for amplification of locus DYS385 on the Y chromosome give quite long amplicons that are difficult to resolve on native polyacrylamide gels. We therefore designed new primers that give much shorter products for easy separation. With this system, two allele variants that were characterized by sequencing as 14.1 (GAAA --> GAAAA) and 14.2 (GA insertion), were identified in two unrelated Northern Thai men due to their decreased mobility. Interestingly, initial capillary electrophoresis mistyped the 14.1 variant amplified with the traditional primers as allele 14. Forty different haplotypes were found in 147 Northern Thais with a haplotype diversity of 0.9430. Haplotype 13-18 (frequency 0.136) is the most frequent one: for comparison: haplotype 14-18 (frequency 0.074) was found to be the most common in a population from Bangkok (n = 95) in an earlier study. This striking difference within Thailand's population probably results from genetic differences in the founding populations. 相似文献

This article analyses effects of German federal election campaigns on citizens’ orientations towards chancellor candidates. Three hypotheses are formulated; they refer to polarization, party politicization, and priming of candidate attitudes; additionally, it is argued that campaign context moderates the effects. The hypotheses are tested empirically using survey data conducted in the election campaigns 1980 to 1998. Empirically, campaign communication polarizes the perceptions of the chancellor candidates; additionally, the perceptions are brought into line with party preferences. Thirdly, priming effects are less common, but in some cases substantial candidate priming can be proved. Hence, election campaigns influence candidate orientations in Germany, and the effect varies according to the political context. 相似文献

Changes in funding, clientele, and treatment practices of public and privately owned substance abuse treatment programs, compelled in part by increased cost containment pressures, have prompted researchers' investigations of the implications of organizational form for treatment programs. These studies primarily probe associations between ownership status, patient characteristics, and services delivered and do not empirically link organizational form or structure to treatment outcomes. Data from the National Treatment Improvement Evaluation Study (NTIES) were used to study the relationship of ownership and other dimensions of publicness identified in the public management literature to patient outcomes, controlling for patient characteristics, treatment experiences, and other program characteristics. A few effects of organizational form and structure on substance abuse treatment outcomes are statistically significant (primarily improved social functioning), although the specific contributions of measures of ownership and publicness to explaining program-level variation are generally small. 相似文献
