Married to intolerance: Attitudes towards intermarriage in Germany, 1900-2006

Marriage is amongst the biggest decisions in life. In general, there is a tendency towards assortative matching people marry others who are relatively similar to themselves. Intermarriage between different social, religious and ethnic groups in most societies is relatively rare (Blossfeld and Timm 2003). Where it occurs, it is associated with more rapid assimilation (Meng and Gregory 2005). The frequency of intermarriage can therefore serve as a useful indicator of tolerant attitudes towards a minority, and of the desire to integrate (Bisin, Topa, and Verdier 2004).In this paper, we analyze under which conditions intermarriage can be used as an indicator of tolerance, and whether such tolerant attitudes persisted in Germany during the last century. We combine information on individual-level attitudes from the German social survey (GESIS) with historical data on marriage patterns.

Meliponini neotropicais: o gênero Ptilotrigona Moure (Hymenoptera, Apidae, Apinae)

O gênero neotropical de abelhas sem ferrão, Ptilotrigona Moure, 1951, é revisado. Três espécies são reconhecidas: Ptilotrigona occidentalis (Schulz, 1904), endêmica do NW da América do Sul - do NW do Equador até o sul de Darién -, e com uma população isolada na Península de Osa - Costa Rica; P. pereneae (Schwarz, 1943), endêmica do oeste da Amazônia, e P. lurida (Smith, 1854), amplamente distribuída na Amazônia. Ptilotrigona lurida e P. pereneae são as únicas abelhas sem ferrão que estocam pólen em associação com leveduras (Candida sp.) e produzem pouco ou nenhum mel. Ninhos são descritos e ilustrados. Holótipos de Trigona suffragata Cockerell, 1922 (sin. de P. occidentalis) e Trigona manni Cockerell, 1912, e exemplares de Trigona heideri Friese, 1900 (sins. de P. lurida), identificados por Friese, e um parátipo de Trigona (Tetragona) heideri pereneae Schwarz, 1943, são estudados. Novo sinônimo: Ptilotrigona lurida (Smith, 1854) = Trigona mocsaryi lutea Friese, 1903 syn. nov. Na análise cladística, espécies de Camargoia Moure, 1989, e Tetragona Lepeletier & Serville, 1828, foram incluídas como grupos externos; a hipótese apresentada é a seguinte: ((((Ptilotrigona lurida, P. pereneae) P. occidentalis)((Camargoia nordestina, C. pilicornis) C. camargoi)) Tetragona goettei). Uma chave de identificação para as espécies e outros aspectos bionômicos também são apresentados.

Productividad, competencia e innovación en la banca privada española (1900-1914)

This study investigates the productivity differences and its sourcesacross a set of banks during the last years of the liberal era of theSpanish banking system (1900-1914). These years were characterised bymajor qualitative and quantitative changes in the banking industry includinga sharp increase in the size of the system, in the number of firms, andin its regional distribution. Employing DEA productivity analysis andthe Malmquist index, we discover that these changes were accompanied bya generalised increase in the efficiency of least productive banks. Also,we observe that the crisis of some regional banking groups, like theCatalan, can be linked with its low productivity levels. In consequence,in the light of our productivity evidence, we conclude that the increasein competition was beneficial for the system because helped to the successof the most efficient banks.
