Does the mass media affect the dispersion of the policy positions of political parties? In this article it is argued that the mass media polarize parties' policy positions because vote‐seeking strategies are more viable if party policy positions are clearly communicated to the electorate and because a vote‐seeking strategy corresponds with parties taking a distinct policy position away from the median. Hence, the main hypothesis is that party policy position dispersion is larger with more mass media penetration. In order to test this argument, a novel dataset on party positions and mass media penetration in 267 Danish municipalities in 2004 is utilized and a new measure of the dispersion of policy positions in multiparty systems is constructed. The analysis corroborates the article's main hypothesis. 相似文献

The PowerPlex 16 BIO multiplex short tandem repeat (STR) system contains the 13 CODIS loci (FGA, TPOX, D8S1179, vWA, D18S51, D21S11, TH01, D3S1358, CSF1PO, D16S539, D7S820, D13S317, and DS5S818), plus two pentanucleotide repeat loci (Penta D and Penta E) and the sex-identifying locus. Amelogenin. The PowerPlex 16 BIO System is optimized for use with the Hitachi FMBIO gel imaging systems. A consortium of seven independent laboratories collaborated to perform the studies defined by the FBI standards for performing a developmental validation, including the evaluation of sample concordance, percent stutter determination, nonprobative casework, precision, sensitivity, mixture determination, effect of substrates, the impact of environmental insults, and species specificity. All samples tested for concordance were consistent except for one sample from the Virginia Division of Forensic Science database that displayed discordance at D13S317, a locus whose primer sequence was altered. Stutter values were comparable to those of other STR multiplex systems, the precision was comparable to other multiplexes analyzed by gel electrophoresis, the DNA profiles were unchanged by the substrate upon which the blood samples were placed, and the nonprobative casework samples re-typed for the PowerPlex 16 BIO System were consistent with previous typing results. When greater than 0.125 ng of DNA was placed into the PowerPlex 16 BIO System amplification reaction, a full profile was generated by all laboratories. The mixture study results were comparable to those reported for other multiplex systems, the environmental study demonstrated a loss of larger molecular weight loci when samples were incubated at elevated temperatures for a prolonged period of time, and the only notable cross species hybridization was observed with primate DNA samples. This extensive validation work performed demonstrates that the PowerPlex 16 BIO System provides STR data of a quality comparable with other PowerPlex STR multiplex kits as well as other widely used STR multiplexes and is thus suitable for evidentiary casework analysis as well as database sample profiling. 相似文献

All cases of assaults with violence (n = 1639) from a well defined area were registered for 1 year. A positive alcolmeter test (% greater than 0.2) was registered in 488 cases (29%). A further 216 patients (13%) were found under the influence of alcohol according to a simple clinical judgement. In nine of ten manslaughter and murder cases alcohol was involved. Young men, 19-29 years of age, comprised the majority of victims. Of the episodes of violence 66% took place during the weekend. In 250 cases the alcohol concentration surpassed 1.5%. Almost 50% of the violence episoded took place in or around restaurants. Blunt violence was concerned in 73% of the episodes. Gunshot was registered in five cases, stabbings in two cases. 相似文献
