Ethnic minority development in Vietnam

This study examines the disparities in living standards between and among the different ethnic groups in Vietnam. Using data from the Vietnam Living Standards Surveys and 1999 Census, we show that ‘majority’ Kinh and Hoa households have substantially higher living standards than ‘minority’ households from Vietnam's 52 other ethnic groups. While the Kinh, Hoa, Khmer and Northern Highland Minorities benefited from economic growth in the 1990s, the position of the Central Highland Minorities stagnated. Decompositions show that even if minority households had the same endowments as Kinh households, this would close no more than a third of the gap in their per capita expenditures. While some ethnic minorities seem to be doing well out of a strategy of assimilating with the Kinh-Hoa majority, others groups are attempting to integrate economically while retaining distinct cultural identities, and a third group is largely being left behind by the growth process.     

The French model of urban services

This article explores the nature of the French model of urban services and more especially its distinguishing features relative to other European countries. The article attempts to answer the basic questions: with such a fragmented communal system how and why has an effective system of service delivery emerged? The answer lies in examining the complex and flexible relationships which exist between the various actors involved ‐ relationships which emerged essentially in the nineteenth century.

Acute Fatal Coronary Artery Dissection Following Exercise‐related Blunt Chest Trauma

Coronary artery injury such as acute coronary dissection is an uncommon and potentially life‐threatening complication after blunt chest trauma. The authors report an unusual autopsy case of a 43‐year‐old healthy man who suddenly collapsed after receiving a punch to the chest during the practice of kung fu. The occurrence of the punch was supported by the presence of one recent contusion on the left lateral chest area at the external examination and by areas of hemorrhage next to the left lateral intercostal spaces at the internal examination. The histological examination revealed the presence of an acute dissection of the proximal segment of the left anterior descending coronary artery. Only few cases of coronary artery dissection have been reported due to trauma during sports activities such as rugby and soccer games, but never during the practice of martial arts, sports usually considered as safe and responsible for only minor trauma.     

Estimating the Number of Contributors to Forensic DNA Mixtures: Does Maximum Likelihood Perform Better Than Maximum Allele Count?

Abstract: Determining the number of contributors to a forensic DNA mixture using maximum allele count is a common practice in many forensic laboratories. In this paper, we compare this method to a maximum likelihood estimator, previously proposed by Egeland et al., that we extend to the cases of multiallelic loci and population subdivision. We compared both methods’ efficiency for identifying mixtures of two to five individuals in the case of uncertainty about the population allele frequencies and partial profiles. The proportion of correctly resolved mixtures was >90% for both estimators for two‐ and three‐person mixtures, while likelihood maximization yielded success rates 2‐ to 15‐fold higher for four‐ and five‐person mixtures. Comparable results were obtained in the cases of uncertain allele frequencies and partial profiles. Our results support the use of the maximum likelihood estimator to report the number of contributors when dealing with complex DNA mixtures.
