Spanish Sociology and Anti-Semitism Between passed prejudice and key to civilization

There is a significant lack of sociological research in Spain about anti-Semitism. At the same time there are alarming anti-Semitic tendencies and anti-Jewish stereotypes which are above the European average. This article aims to explain this lack of sociological research about anti-Semitism in Spain. Therefore two types of explications are offered: on the one hand side some structural problems will be shown which sociology in general had since its beginnings and which complicate the understanding of anti-Semitism. Furthermore explications regarding the specific social and historic situation in Spain and of Spanish sociology in particular will be exposed. It will be shown that for its rationalistic character and with the exception of very few authors – who are considered marginalized for practical research – sociology in general has had enormous problems in understanding anti-Semitism. The specific historic situation, Francoism, the dispute about the historic memory and the delayed institutionalisation of sociology could also explain the lack of sociological interest in the topic especially in Spain. The article shows that the study of anti-Semitism is not only relevant for struggling against this burden of society in many of its variants. Furthermore, thinking about anti-Semitism can help sociology to recognise its own epistemological problems. It can serve to criticise and improve instruments of sociological research by showing the limitations of the sociological approach and to uncover the importance of interdisciplinary research for understanding specific social phenomena. In that sense, anti-Semitism, far from being a marginal subject, can be considered a key topic in the process of civilisation and it can help us to decipher the contemporary Spanish society.

Interpolation formula between very low and intermediate-to-high damping Kramers escape rates for single-domain ferromagnetic particles

It is shown that the Mel'nikov-Meshkov formalism for bridging the very low damping (VLD) and intermediate-to-high damping (IHD) Kramers escape rates as a function of the dissipation parameter for mechanical particles may be extended to the rotational Brownian motion of magnetic dipole moments of single-domain ferromagnetic particles in nonaxially symmetric potentials of the magnetocrystalline anisotropy so that both regimes of damping, occur. The procedure is illustrated by considering the particular nonaxially symmetric problem of superparamagnetic particles possessing uniaxial anisotropy subject to an external uniform field applied at an angle to the easy axis of magnetization. Here the Mel'nikov-Meshkov treatment is found to be in good agreement with an exact calculation of the smallest eigenvalue of Brown's Fokker-Planck equation, provided the external field is large enough to ensure significant departure from axial symmetry, so that the VLD and IHD formulas for escape rates of magnetic dipoles for nonaxially symmetric potentials are valid.
