Institutions and Vote Unity in Parliaments: Evidence from 33 National Chambers

The paper looks at the relationship between institutions and vote unity in national parliaments with the help of a large data set of votes from 33 national parliaments. The tests run are the first to confirm empirically the relationship between vote of confidence procedure and vote unity. The paper also provides a theoretical explanation for why the existence of the confidence procedure influences vote unity despite being used only rarely. The vote of confidence influences votes through the development of control mechanisms as well as the selection of party members who are more ideologically united. This study also challenges the view that electoral rules which make candidates individually accountable to voters necessarily lead to more vote defections. The findings suggest that higher personal accountability decreases vote unity only if party leaders do not control candidate nomination. Parties that rely on government finance for campaigns are also more united.     

Increasing Representative Accountability through Electoral Laws: The Consequences of the 2008 Romanian Electoral Reform

The paper tests the effects of the 2008 Romanian electoral reform on the behaviour of MPs with the help of personal interviews conducted post reform. The reform was meant to make MPs more responsive to the needs of constituents, which in turn should lead to more constituency input in the legislative process, while at the same time yielding proportional results. The paper finds that there are few channels for the transmission of constituents' needs to MPs, and the existing channels are used for petty requests that have little to do with the legislative procedure. This in turn encourages the development of clientelistic ties between representatives and voters, which benefit wealthier candidates. The study also finds that although the new system translates votes into seats closely, small parties may still be disadvantaged because of what Duverger (1954 Duverger, M. (1954). Political parties: Their organization and activity in the modern state, New York, NY: John Wiley. [Google Scholar]. Political parties: Their organization and activity in the modern state. New York: John Wiley) calls the psychological aspects of the wasted vote problem.     

The Interplay Between Diabetes and Pancreatitis: Two Case Reports of Sudden,Natural Deaths and a Review of the Literature

Diabetes mellitus (DM) is a common disease involving insulin resistance or deficit that, when left unchecked, may cause severe hyperglycemia and subsequent end‐organ damage. Acute pancreatitis (AP) is inflammation of the pancreas that can lead to significant morbidity and mortality. AP and DM both account for a significant amount of sudden deaths, and rarely both disease processes may be present in the same decedent, causing some difficulty in wording the cause of death statement. Although much research has been directed at studying the causes and risk factors for AP and DM, there is a complex interplay between these diseases that is not fully understood. This study presents two autopsy cases of sudden, natural deaths that illustrate this interplay, along with a review of the literature. An algorithm for differentiating AP and DM is then discussed in the context of the presented cases as a proposed aid for forensic pathologists in the certification of such deaths.     

Y-chromosomal STR haplotypes in a population from the Amazon region, Brazil

Haplotype and allele frequencies of the nine Y-STR (DYS19, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS385 I/II) were determined in a population sample of 200 unrelated males from Belém, Brazil. The most common haplotypes are shared by 1.5% of the sample, while 186 haplotypes are unique. The haplotype diversity is 0.9995+/-0.0006. The data obtained were compared to those of other Brazilian populations. AMOVA indicates that 99.91% of all the haplotypical variation is found within geopolitical regions and only 0.09% is found among regions.     

Nucleotide variability of HV-I in Afro-descendents populations of the Brazilian Amazon Region

The analysis of genetic variation in the nucleotide sequences of mitochondrial DNA, provides unique information about the population diversity and human identification. In this study, the mitochondrial DNA sequences of the first hypervariable region (HV-I) were analyzed in 243 unrelated individuals of seven Afro-descendents populations of the Amazon Region. Sequence polymorphisms were detected using PCR and direct sequencing analysis. A total of 133 different haplotypes were found determined by 97 variable nucleotides. Each one of the three more frequent haplotypes was shared by 9 samples and 91 sequences were unique. The genetic diversity was estimated to 0.9898+/-0.0016 and the probability of two random individuals showed identical mitochondrial DNA (mtDNA) haplotypes were 1.2%.
