This paper explores cultural integration paths of eight migrant groups in Switzerland. It specifically analyzes the evolution of objective behaviors and subjective attitudes of migrants from the first to the second generation. In order to deepen the analysis, the cultural integration of migrants is further examined from different perspectives: across cohorts (older vs. younger migrants) and acr...

Abstract. Let C be an extremal self-dual binary code of length 72 and g ∈ Aut(C) be an automorphism of order 2. We show that C is a free F2〈g〉 module and use this to exclude certain subgroups of order 8 of Aut(C). We also show that Aut(C) does not contain an element of order 10. Combining these results with the ones obtained in earlier papers we find that the order of Aut(C) is either 5 or divi...

We experimentally investigate the extent to which social observability of one’s actions and the possibility of social non-monetary judgment affect the decision to engage in rule breaking behavior. We consider three rule breaking scenarios — theft, bribery and embezzlement — in the absence of any formal enforcement mechanism. By involving a student sample characterized by cultural heterogeneity ...

A model of social interactions shows why and when reputation concerns may support an ‘underclass’ culture of street crime where the incentives for such behavior are otherwise weak. Those who do not gain from street crime directly nevertheless find it optimal to invest in violence and thereby build a reputation that will earn them deference from the rest of the community. Even when the fraction ...

Cultural variables in economic analysis have recently experienced a strong renewal. This evolution sheds a new light on the old debate between the "Beckerian Model" of fertility and the "Synthesis Model" of fertility. In this paper, I propose a fertility model making the long run evolution of culture endogenous. The whole population is divided into two alternative cultures corresponding to spec...

We study the e¤ect of culture on important economic outcomes by using the 1970 Census to examine the work and fertility behavior of women 30-40 years old, born in the U.S., but whose parents were born elsewhere. We use past female labor force participation and total fertility rates from the country of ancestry as our cultural proxies. These variables should capture, in addition to past economic...

Immigrants, Ethnic Identities and the Nation-State In the Western world, multiculturalism has become the way to view and form “nationhood,” igniting the interest to understand and model identity. The complexity of identity formation, however, has been firm and ethnic and national identities have been deviating more and more. In this paper, we seek to investigate the nature, role and relationshi...

Quasi-monochromatic X-ray emission induced by MeV-proton bombardment onto metallic targets was applied to radiography of small samples. The X-ray energy was adjusted in the range of z4–23 keV by changing the target material. The radiograms were recorded on an imaging plate. A small phantom made of Lucite was prepared for the test of photography using a contrast medium (RuCl3$H2O; ruthenium chlo...
