Validity and Defeasibility in the Legal Domain

In jurisprudential literature, the adjective ‘defeasible’ appears as a predicate of many terms: concepts, laws, rules, reasoning, justification, proof, and so on. In this paper, we analyze the effects of some versions of the thesis of the defeasibility of legal norms on the reconstruction of the notion of legal validity. We analyze some possible justifications of this thesis considered as a claim concerning validity, and enquire into two possible sets of problems related to the defeasibility of the criteria of identification of a legal system. We also provide a formalization of some options regarding defeasible criteria of identification, which can be used as a tool for meta-jurisprudential analysis. Finally, the thesis according to which defeasibility is better conceived of as a feature of legal application is examined and questioned.     

The assessment of intimate partner violence in Spanish women: the index of spouse abuse

We aimed to analyze the internal consistency and construct validity of the Spanish version of the Index of Spouse Abuse (ISA) in a representative sample of 8,995 women attending general practice in Spain in 2006-2007. The factor structure analysis shows that the ISA measures four intimate partner violence (IPV) dimensions: emotional, physical, and sexual abuse, and controlling behavior. Cronbach alpha ranges from .82 (sexual factor) to .94 (emotional). Construct validity analysis shows that IPV is associated with poorer self-perceived health, higher psychological distress, and lower tangible social support. The ISA can help make more visible forms of gender violence in the intimate relationship that sometimes are not recognized as such, like sexual violence or controlling behavior. This can contribute to the development of specific interventions for women experiencing IPV, considering the specificities of the violent acts experienced.     

How Universal is Behavior? A Four Country Comparison of Spite and Cooperation in Voluntary Contribution Mechanisms

This paper studies behavior in experimentswith a linear voluntary contributionsmechanism for public goods conducted inJapan, the Netherlands, Spain and the U.S.A.The same experimental design was used inthe four countries. Our `contributionfunction' design allows us to obtain a viewof subjects' behavior from twocomplementary points of view. It yieldsinformation about situations where, inpurely pecuniary terms, it is a dominantstrategy to contribute all the endowmentand about situations where it is a dominantstrategy to contribute nothing. Our resultsshow, first, that differences in behavioracross countries are minor. We find thatwhen people play `the same game' theybehave similarly. Second, for all fourcountries our data are inconsistent withthe explanation that subjects contributeonly out of confusion. A common cooperativemotivation is needed to explain the data.     

The 2015 Catalan election: a de facto referendum on independence?

The 2015 Catalan regional election, held on 27 September, was framed as a proxy for an independence referendum by the pro-independence parties. This was meant to bypass the PP-led central government's opposition to permit an official referendum. After an election campaign clearly dominated by the independence issue, the results delivered a majority of seats but not of votes for the pro-independence camp. However, the reading of the results as a de facto referendum is not straightforward. Growing polarization around the independence issue resulted in the emergence of two main blocs, for and against independence; in the polarization of stances within the blocs; and in substantial changes in the Catalan party system. The lack of agreement between the secessionist parties over the reappointment of Artur Mas as president almost triggered a new election but, in a last-minute move, Mas stepped aside. The new government aims to declare independence in 18 months.     

Metropolitan challenges and reform pressures across Europe – the perspectives of city mayors

Metropolitan governance arrangements and their policy purposes have been a matter of debate among researchers and practitioners around the globe. While we may trace three broad schools of metropolitan governance – reform school, public choice theory and new regionalism – with each still having its proponents, we are interested to learn whether there are assumptions on metropolitan governance that have today become general knowledge among urban political elites. By investigating the attitudes and perceptions of city mayors across Europe, we show that functional multipurpose governance bodies are indeed more generally associated with equitable service distribution, whereas the preconditions for cost-efficiency and sustainable development are more equivocally placed at different modes of governance. Moreover, we show that a perceived general lack of problem-solving capacities does not automatically translate into pressures for metropolitan reform, but it is only in combination with a general disaffection with the governance structures currently in place.     

Railway Development and the Economic and Political Integration of the Balkans,c. 1850–2000

This article uses the evolution of the railways to examine the relationship between the level of economic integration and external political influences in the Balkans over a period of 150 years. The analysis focuses on two key themes: the long-term spatial evolution of the railway network and external influences on this infrastructure. To undertake this territorial analysis, we first established a Historical Geographical Information System (HGIS) that allowed us to interpret data on the evolution of the railway network and then related this to other data on themes such as changing international borders and the nationality of investment.     

Jewish population genetic data in 20 polymorphic loci

Frequency data of 20 polymorphisms (13 autosomal and 6 Y-chromosome STRs and the Alu-insertion YAP) were determined in a sample of 124 unrelated Jewish individuals from Ashkenazi, Sephardic, North African and Oriental origin. The a priori statistical power of the set of studied loci was highly discriminating (PD=1 in 2.393 E+15 individuals for autosomal STRs, and a probability of finding two unrelated males with the same haplotype of less than 0.01). Some significant population differences were registered between Jews and other Circummediterranean populations in Y-chromosome loci frequencies.
