Online reference database of European Y-chromosomal short tandem repeat (STR) haplotypes

The reference database of highly informative Y-chromosomal short tandem repeat (STR) haplotypes (YHRD), available online at http://ystr.charite.de, represents the largest collection of male-specific genetic profiles currently available for European populations. By September 2000, YHRD contained 4688 9-locus (so-called "minimal") haplotypes, 40% of which have been extended further to include two additional loci. Establishment of YHRD has been facilitated by the joint efforts of 31 forensic and anthropological institutions. All contributing laboratories have agreed to standardize their Y-STR haplotyping protocols and to participate in a quality assurance exercise prior to the inclusion of any data. In view of its collaborative character, and in order to put YHRD to its intended use, viz. the support of forensic caseworkers in their routine decision-making process, the database has been made publicly available via the Internet in February 2000. Online searches for complete or partial Y-STR haplotypes from evidentiary or non-probative material can be performed on a non-commercial basis, and yield observed haplotype counts as well as extrapolated population frequency estimates. In addition, the YHRD website provides information about the quality control test, genotyping protocols, haplotype formats and informativity, population genetic analysis, literature references, and a list of contact addresses of the contributing laboratories.     

School choice in Chile: Is it class or the classroom?

Skeptics of school choice are concerned that parents, especially low‐income ones, will not choose schools based on sound academic reasoning. Many fear that, given choice, parents will sort themselves into different schools along class lines. How‐ever, most surveys find that parents of all socioeconomic groups cite academic aspects as important when choosing a school. Moreover, almost no parents refer to the social composition of the student body. Many advocates of choice hold up these results as proof that choice will produce desirable outcomes. However, these results may not be reliable because they may simply be verbal responses to survey items rather than indicators of actual behavior. In this research, we report on the search behavior of parents in the Metropolitan Region of Santiago, Chile, examining how they construct their school choice sets and comparing this to what they say they are seeking in choosing schools. The data indicate that parental decisions are influenced by demographics. Based on this evidence, we argue that unfettered choice may reduce the pressure on schools to improve their performance and could potentially increase stratification. © 2006 by the Association for Public Policy Analysis and Management     

Politischer Opportunismus und Haushaltsdefizite in den westdeutschen Bundesländern

This article analyzes fiscal political business cycles in the West-German Länder. By linking the theory of political business cycles with the insights of the theory of economic voting, I argue that the German Länder governments do not have an incentive to raise the budget deficit in order to signal economic competence to the electorate. Despite having an incentive to spend more before an election in order to provide public goods to the voters, governments cannot finance the supply of public goods with higher deficits because voters prefer healthy fiscal policies. An empirical analysis of the West-German Länder between 1970 and 2003 bolsters the theoretical claims. A government that expands the deficit before an election thus experiences a loss in voter support. Consequently, governments tend to reduce the budget deficit in pre-election years.     

Hybrid Warfare,International Negotiation,and an Experiment in “Remote Convening”

The authors are leading a multinational effort to understand the effects of “hybrid” warfare on international commercial negotiation. The start-up process is itself essentially a negotiation, among about forty individual practitioners and scholars with very diverse backgrounds, over whether and how they will work together. In a pandemic, a key risk is that the necessary cooperation and trust will be harder to build, particularly among professionals who are dealing with security-sensitive issues and who have never met each other. This article discusses the current necessity of replacing the in-person model for eliciting such cooperation which the authors had developed previously for large collaborative projects, and describes a “remote convening” replacement process.     

A new sign for the establishment of gunshot in suicide?

Two cases involving deadly bullet shots to the head are reported (entry wounds at the right temple, shots fired at absolutely close range, 7.65 or 9 mm caliber). In both cases bleeding was determined in the fissure of the right shoulder joint. This bleeding can be explained by hyperextension and extreme position of the joint at the time of the gun firing. Should further cases of bleeding be confirmed during additional autopsies, then this bleeding could be an indication of death "by one's own hand."
