Past research suggests that beliefs and emotions operate as partially distinct determinants of political attitudes. In addition, while positive and negative beliefs about a political object are bipolar in structure, positive and negative emotions have been demonstrated to be relatively independent. In this past research, beliefs and emotions have been assessed with different measures. Yet current models of survey responding suggest that responses to survey items are often influenced by the manner in which the researcher poses the questions. As such, it is not clear whether the uniqueness of these belief and emotion measures reflects a bona fide difference between two underlying constructs, or merely an artifactual difference induced by differing methods of measurement. In this study, beliefs and emotions are shown to operate as partially unique predictors of candidate evaluation even when employing corresponding methods of measurement. The independence of positive and negative emotion, however, only arises when employing a dichotomous measure. When employing ordinal measures, positive and negative emotions contain a substantial component of bipolarity. The theoretical implications of these findings are discussed. 相似文献

Allele and genotype frequencies for three recently described short tandem repeat loci D1S1656, D12S391, and D18S535 were determined in a population sample from Asturias (North Spain). The loci were amplified using a fluorescence based PCR method and were typed automatically. No deviation from Hardy-Weinberg expectations were observed. The three loci proved to be highly discriminating and the allele frequencies observed are similar to those of the other European populations that have been typed for these loci to date. 相似文献

A simple procedure based on a common silica gel column chromatography for the isolation of Delta9-tetrahydrocannabinolic acid A (Delta9-THCA-A) from hemp in a multi-milligram scale is presented. Further, the decarboxylation reaction of Delta9-THCA-A to the toxicologically active Delta9-tetrahydrocannabinol (Delta9-THC) at different analytical and under-smoking conditions is investigated. Maximal conversion in an optimised analytical equipment yields about 70% Delta9-THC. In the simulation of the smoking process, only about 30 % of the spiked substance could be recovered as Delta9-THC. 相似文献

In order to use genetic loci in forensic identity testing, some population data are needed. This paper presents a report of allele frequency data for the loci HUMTH01, HUMTPOX and HUMVWA in a population sample from Northern Spain. No deviation from the Hardy-Weinberg equilibrium was detected in any of the three markers investigated and there was no evidence of association between the alleles of these loci. Statistical analysis was also carried out to obtain some parameters of medicolegal interest and comparative studies were carried out with other populations studied to date for these five loci. The Asturian sample does not differ substantially from other Caucasian and Spanish populations. 相似文献

Zusammenfassung Mit Urteil vom 29. Oktober 2007 hat das Amtsgericht Hannover einen Angler wegen Versto?es gegen
§ 17 Nr. 2 b des Tierschutzgesetz (TierSchG) zu einer Geldstrafe in H?he von 15 Tagess?tzen
verurteilt. Nach den Feststellungen des Gerichts hatte der Angeklagte am 16.11.2007 sechzig Rotfedern zum
Zwecke der Verwendung als K?derfische in einem insgesamt zehn Liter fassenden, jedoch zeitweise lediglich
mit sieben Litern Wasser gefüllten ovalf?rmigen Eimer zur weiteren Verwendung zwischengeh?ltert.
Im Verlauf der H?lterung schwammen einige der Fische an die Oberfl?che, woraus das Gericht auf
einen zwischenzeitlichen Sauerstoffmangel im Beh?ltnis schloss. Nach Auffassung des AG Hannover stellt
das Verhalten des Anglers insgesamt einen Versto? gegen § 17 TierSchG in der Modalit?t des
Zufügens von l?nger anhaltenden erheblichen Leiden nach Nr. 2 b dar. 相似文献
