Time-consistent monetary policy under output persistence

This note merges the fact that real activity is persistent with a Barro-Gordon type model of endogenous monetary policy. It shows that persistence crucially affects policy choices. This applies in non-cooperative games with a finite horizon, and in games with an infinite horizon. Always, enforceable inflation announcements move higher when output persistence increases. Policymakers who discount future utility by 10% annually produce about ten times as much inflation under near-hysteresis as in a natural-rate scenario. A change in the policymaker's time preference may affect inflation both ways, depending on present time preference and persistence.     

Stability and Internal Consistency of the Offer Self-Image Questionnaire: A Study of Finnish Adolescents

Reliability of the Offer Self-Image Questionnaire (OSIQ) was assessed with two measures—internal consistency and stability—in Finnish children aged 13. The OSIQ was administered to 268 normal 13-year-old pupils (129 girls and 139 boys). Three weeks later, a third of the pupils (N = 88) were randomly selected for retesting. Eighty-three teenagers completed the questionnaire in an acceptable manner. The internal consistency of the test was verified for each scale using Cronbach . To estimate the stability of the test, Pearson correlation coefficients were calculated, and the mean raw scores for each scale were compared with those in the retest. The internal consistency of the test was fairly good ( = 0.54–0.84) for the majority of scales, except for scales S5 and S12 ( = 0.30–0.41). The stability of scales S1, S4, S5, S7, and S10 was good. On the basis of these two measures, we conclude that for Finnish adolescents, the OSIQ is sufficiently reliable only with respect to scales S1, S4, S7, and S10.     

A systematic and quantitative analysis of PCR template contamination

A quantitative and systematic analysis is provided for ubiquitously present template DNA interfering with the quantification of human DNA by PCR. Two sources contributing to DNA background were identified. The first one is interpreted as DNA present in chemicals and on equipment and the second as caused by operator handling. The amounts were equivalent to 2.5 and 8.9 pg per mL of sample, and the estimated frequencies of contamination were 65 and 35%, respectively, resulting in an effective limit of detection of 17.4 pg/mL. Below this level--named effective laboratory background--a result could not be considered as authentic. Knowledge of these parameters is important for laboratories that analyze minute amounts of human DNA by PCR for purposes such as quantification, typing, and sequencing.     

Forensic medicine experiences in Kosovo

In summer 1999, a German forensic team of CID officers and forensic pathologists was sent to Kosovo on request of the International Criminal Tribunal for the former Yugoslavia (ICTY) to investigate possible war crimes. For this purpose, witnesses had to be found and interrogated and graves of victims had to be located and the bodies exhumed and examined forensically. Roughly 200 bodies have been found and examined during the campaign that were predominantly of male sex and showed mainly gunshot wounds. A high percentage of all bodies could be identified. The article deals with different forensic-pathologic aspects of such an investigation.     

Variations in traditional marriage and family forms: Responses to the changing pattern of family-based social security systems in Sierra Leone and Kenya

A multitude of family forms can be found in African societies, and the functions we associate with the European term “family” do not necessarily belong to any specific form. The variety in the formation of different residence, consumption, and production units becomes obvious through the analysis of the social structure of individual b peoples, as well as through inter-ethnic comparisons. This article focuses on the differences between various types of social organization of an East- and a West-African people, and analyzes the complexities of and changes in family structures in the relevant socio-political and economic contexts. It also looks at the impact of the introduction of public administration and the commercialization of agriculture on social dynamics and family forms.     

Prospects of peace negotiation in Papua

The Papuan conflict resembles the conflict in Aceh. Also some of the models of conflict resolution can undoubtedly be imported for Papua from Aceh. However, the existence of large migrant groups, the lack of a coherent organization of the rebel side, and the more extreme nature of economic grievances in Papua than in Aceh, give the conflict problem in Papua its own characteristics. This article speculates about how much Papua could learn from its own past and how much lessons it could emulate from other areas to establish its own mechanisms of peace negotiation.     

European Associations in Higher Education

The last fifteen years have witnessed a drastic increase in higher education cooperation in Europe. In parallel to this development, the number of European associations in higher education has grown considerably. This article constitutes a first systematic look at these organisms. After providing a working definition, it tries to encapsulate the rationale and the main activities of these associations, followed by a first attempt at a typology. A short history of the European higher education association is combined with an analysis of the links between its large-scale emergence and the provision of higher education cooperation programmes by the European Union. This revised version was published online in July 2006 with corrections to the Cover Date.
