Belgium has one of the most fragmented party systems of any modern democracy. This article asks the following questions: is party fragmentation linked to the importance of the ethno-regionalist vote or to the rules of the electoral system? Has party fragmentation also produced centrifugal or polarised multipartyism (between the regions, but also within Flanders, given the spectacular rise of the Vlaams Blok)? What explains the difference in party fragmentation between Flanders and Wallonia? What are the dimensions of party competition in each community and what are the socio-demographic and attitudinal characteristics of the different electorates? Which steps have the political elites taken to cope with the increasing fragmentation of the party landscape and growing voter volatility? To what extent has the increasing divergence between the regional party systems led to the building of asymmetrical coalitions at the federal and regional levels of government? The splitting of the Belgian party system into two, albeit still fragmented, party systems has further complicated the problems of coordination within a polarised, multi-cleavage and multilevel system that seriously undermines the stability of the entire political system. 相似文献

Recent studies have started to use media data to measure party positions and issue salience. The aim of this article is to compare and cross-validate this alternative approach with the more commonly used party manifestos, expert judgments and mass surveys. To this purpose, we present two methods to generate indicators of party positions and issue salience from media coverage: the core sentence approach and political claims analysis. Our cross-validation shows that with regard to party positions, indicators derived from the media converge with traditionally used measurements from party manifestos, mass surveys and expert judgments, but that salience indicators measure different underlying constructs. We conclude with a discussion of specific research questions for which media data offer potential advantages over more established methods. 相似文献

Critique of interpretation of high levels of heteroplasmy in the human mitochondrial DNA hypervariable region I from hair 总被引:7,自引:0,他引:7
The phenomenon known as heteroplasmy can be operationally observed in some human mitochondrial DNA (mtDNA) samples. Typically, heteroplasmy manifests itself in an individual presenting two mtDNA species that differ at a single base. Heteroplasmy at two, and even possibly three sites, also may occur, but at very low rates. A recent report (Grzybowski, 2000, see ref. [13]) suggests that much higher levels of mtDNA (point substitution) heteroplasmy can occur in hair. This observation is contrary to the experience of the forensic mtDNA community. There are several explanations for the unusual findings of high levels of heteroplasmy. First, the template quantities of DNA are approximately three orders of magnitude higher than required for mtDNA sequencing, and an excessive number of amplification cycles were used. Thus, the protocol used did not follow routine practices by the forensic community. Second, there are misidentifications and tabular errors that call into question the reliability of the findings. Third, by comparing the natural human mtDNA variation with a reference sample population with that observed in the heteroplasmy in hair study, the data are inconsistent with population genetic expectations. The observation of high levels of heteroplasmy may be due to contamination of the samples and/or possibly the amplification of nuclear pseudogenes. The results observed in the heteroplasmy in hair study do not apply to other methods of mtDNA analysis and cannot be used to question the reliability of the current forensic mtDNA practices. 相似文献

Human mitochondrial DNA (mtDNA) analysis is a valuable forensic tool, useful in cases where the amount of extracted DNA is low or highly degraded. Population databases are used to determine the relative rarity of a particular profile obtained in a forensic case. Rather than full DNA sequence information, sequence profiles are compared to a reference sequence, and the differences from the reference are recorded in forensic databases. A standard method is proposed for characterizing length variants, and examples are described using actual human control region mtDNA profiles. Consistency in alignment and nomenclature avoids inadvertently describing two sequences as different when in fact they are the same. 相似文献

Les résultats principaux de cette recherche ont été obtenus, grâce à une enquête par questionnaire, auprès de 232 représentants de la société civile du pays. Les répondants sont favorables à l'adhésion à l'Union Européenne et à une intensification des échanges avec les pays d'Europe centrale et orientale. Par ailleurs, ils fustigent la timidité du gouvernement ou son absence de vision. Mais cette critique est tempérée par le fait que nos interlocuteurs sont conscients de la faible marge de manoeuvre des dirigeants du pays. En outre, les acteurs non étatiques ne manquent pas de souligner le dynamisme des opposants à l'Europe tandis qu'un sentiment d'apathie politique se dégage du côté patronal et des entreprises. Un autre élément concerne les moyens d'action officieux. Certes, les acteurs non étatiques n'ignorent nullement l'influence du processus formel en politique européenne. Toutefois, ils accordent une place très importante aux moyens d'action informels. Ainsi l'on peut mieux comprendre le rôle attribué aux dirigeants des associations socio-professionnelles, à la création des réseaux et à l'accès aux canaux d'influence. 相似文献

We herein report the case of a 36‐year‐old man who died suddenly after a fight with another man. Forensic investigations included unenhanced computed tomography, postmortem angiography, autopsy, histology, neuropathology, toxicology, and biochemistry and allowed a traumatic cause of death to be excluded. An electrocardiogram recorded some years prior to death revealed the presence of an early repolarization pattern. Based on the results of all investigations, the cause of death was determined to be cardiac arrhythmia and cardiac arrest during an emotionally stressful event associated with physical assault. Direct third party involvement, however, was excluded, and the manner of death was listed as natural. The case was not pursued any further by the public prosecutor. 相似文献

Americans most often think about government in terms of its ability to grapple with issues of redistribution and race. However, the September 11 terrorist attacks led to a massive increase in media attention to foreign affairs, which caused people to think about the government in terms of defense and foreign policy. We demonstrate that such changes in issue salience alter the policy preferences that political trust shapes. Specifically, we show that trust did not affect attitudes about the race‐targeted programs in 2004 as it usually does, but instead affected a range of foreign policy and national defense preferences. By merging survey data gathered from 1980 through 2004 with data from media content analyses, we show that, more generally, trust's effects on defense and racial policy preferences, respectively, increase as the media focus more attention in these areas and decrease when that attention ebbs. 相似文献
