A report of an international collaborative experiment to demonstrate the uniformity obtainable using DNA profiling techniques.

This paper describes a collaborative exercise intended to demonstrate whether uniformity of DNA profile results could be achieved between different European laboratories. It was shown that this goal can be obtained provided that a common protocol is followed (specifically the use of a common electrophoretic buffer as being the most important parameter). Generally, lower molecular weight loci (with lower molecular weight fragments) such as YNH24 perform better than higher molecular weight loci such as MS43a. The results of the exercise are discussed in relation to the objectives of the European DNA profiling group (EDNAP).

Social Desirability,Opportunism and Actual Support for Farmers’ Market Organisations in Ethiopia

One of the striking issues in the literature on farmers’ market organisations (FMOs) is that farmers generally report quite positive opinions regarding the services of their FMO, while, at the same time, actual sales reveal a much more reserved attitude. We argue that farmers may feel social and/or opportunistic pressure to express positive opinions concerning the FMO, to donors and policy-makers, which are not necessarily in line with their actions. This article proposes a list experiment method to control for this bias. The method shows that especially farmers who express strong support for the FMO seriously hesitate to speak freely.     

Parties and Voters: What Creates the Ties?

The increasing instability in the electorate and the party system forces us to reconsider the Lipset-Rokkan thesis about the frozen party system. In this approach, cleavages played a major role, but in Western Europe, this role has diminished significantly. The frequent shifts in voter allegiance call for a new understanding of the mechanisms that connect voters and parties. A reinterpretation of the concepts of a "frozen party system" or "cleavages" is not enough. We need a new theory about the strategic interaction between parties and a floating electorate.     

Determinanten politischer Kultur am Beispiel des Schwyzer Stimmverhaltens

The new institutionalist approach is heavily committed to the idea that institutions matter. This article explores this commitment by examining the institutions of corporatism using comparative data in order to relate these to those of Konkordanzdemokratie. A neo-institutionalist perspective may be employed to illustrate how the institutions of Konkordanzdemokratie and macrocorporatism are related, both in terms of their origins as well as their policy outputs and outcomes. This article shows that both the conditions and the configuration of outputs and outcomes of Konkordanzdemokratie and corporatism are different. Therefore, one should clearly distinguish between these two sets of institutions. In a cross-sectional approach the configuration of socio-economic outcomes connected with these institutions are not as impressive as often claimed.     

Statistical analysis of the measurement errors in the determination of fragment length in DNA-RFLP analysis.

DNA from human whole blood samples was digested with the restriction enzyme HinfI and RFLP analysis performed using the single locus probes MS1, MS31, MS43a and YNH24. The intergel variation of 3291 duplicate measurements of fragment lengths in terms of basepairs was investigated. The difference between two measurements of the same fragment on different gels increased approximately exponentially with increasing fragment length. After transformation of the fragment length into a normalized migration distance it was found that the difference between two transformed measurements was normally distributed with a S.D. (0.70 mm) which was independent of the fragment length. The errors of band 1 and band 2 on the same lane were correlated (r2 = 0.8). It is useful in the calculation of frequencies and in retrieval procedures and also in the calculation of likelihood ratios to be able to use a S.D. which is independent of the fragment length.     

Public Finance Variations: A New Approach*

Few themes have aroused so much interest and contention as the search for environmental determinants of public policy. One major problem area in this debate concerns the identification of explanatory variables accounting for the cross-country variation in public expenditures. As no agreement has been reached about the basic issues involved, it seems appropriate to formulate a new approach to the problem of accounting for public finance patterns. An argument is presented to the effect that the employment of more rigorous econometric tools may help us draw an outline of the structural pattern behind the public household. The analysis indicates that we must abandon the idea of identifying stable structures that describe the relationships between the public household and the environment.
