Tightened Immigration Policies and the Self‐Employment Dynamics of Mexican Immigrants

As the U.S. government has intensified its crackdown on illegal immigration in recent years, an important question to ask is how undocumented immigrants react to the stricter enforcement of immigration laws. This paper seeks to answer whether they increasingly choose self‐employment in an effort to avoid apprehension and subsequent deportation. To guard against endogeneity bias that might stem from increased enforcement in reaction to illegal immigration, the empirical analysis makes use of the September 11 terror attacks (9/11), which inadvertently triggered stricter immigration enforcement nationwide, as a natural experiment. Using a difference‐in‐differences approach and data from the Current Population Survey between 1996 and 2006, this paper examines the changes in the self‐employment choices of male and non‐citizen Mexican immigrants (a proxy for undocumented immigrants) compared to less‐educated Whites (the control group). The findings indicate that male and non‐citizen Mexican immigrants are substantially more likely (40 percent) to enter into self‐employment than less‐educated Whites after 9/11. The analysis further suggests that this finding is not driven by the 2001 recession that coincided with the terror attacks. The increased entries are mainly observed in the group that is most likely to be in the United States illegally and in those who face strong economic incentives. In addition, increased entries are not driven by increased unemployment among Mexican immigrants after the 9/11 event, but, rather, they reflect a change in the behavior of the unemployed Mexican immigrants, perhaps due to changes in perceived risks of detection and deportation.     

The Struggle For Baltic History

Low levels of social protection under the framework of neo-liberal ideology have characterized Baltic welfare regimes since the 1991 restoration of independence in these countries. The policies’ negative social consequences intensified during the years of austerity, 2007–2009. Although there have been trade union protests against the measures, these have been powerless and scattered. About 10% of the Latvian and Lithuanian workforce fled the country during the first decade of the 2000s, whereas an even greater proportion of the Estonian workforce has temporarily done so. In Albert O. Hirschman’s terms, “exit” occurs in the absence of “voice”. Moreover, disillusionment caused by deteriorating conditions and limited political choices generate a particular type of loyalty without a sense of influence.     

“The Mother of Reason and Revelation”: Benjamin on the Metaphysics of Language

This paper is a reconstruction of Walter Benjamin's philosophy of language, especially as it expressed in 1916's “On Language as Such and the Language of Man”. I read Benjamin's theory as a contribution to what Charles Taylor has called the “expressivist” tradition that includes eighteenth century thinkers like J.G. Herder and J.G. Hamann. Hamann's work and his interpretation of the theological concept of condescension are of particular importance. Although Benjamin's views are often regarded as impenetrable or mystical, they are relevant to and, in part, motivated by concerns of more mainstream twentieth century philosophy of language, in particular Russell's paradox. His “metaphysics of language” understands reference or designation, central to analytic theories of meaning, as derived from a more fundamental, aesthetic meaning.     

Molecular characterisation and population genetics of the DYS458 .2 allelic variant

We recently found a number of intermediate DYS458 alleles, indicated as .2. This allelic variant is distributed in several populations, but currently no information is available regarding the molecular structure and the genealogical correlation of chromosomes with this variant. The molecular characterisation of such allele, its worldwide distribution and the correlated evolutionary history are the subject of the present paper. Molecular and genealogical data are suggestive of a single origin for the .2 variant. Phylogeographic analysis points to either a Middle East or East African origin, but additional data is necessary to clarify this point. Our results suggest that the .2 variants is a stable polymorphism and that it could be used for population studies.     

Introduction: contact and domestic abuse

ABSTRACT

This article introduces the special issue of the Journal of Social Welfare and Family Law on contact disputes and allegations of domestic abuse. It first describes the aims and findings of the International Symposium on Contact Disputes and Allegations of Domestic Violence – Identifying Best Practices at which the papers in the special issue were originally presented. It then outlines the position in England and Wales regarding allegations of domestic abuse in child arrangements cases, highlighting the difference between the ‘law in the books’ and the ‘law in action’. Thirdly, it discusses the research evidence on another prominent international approach to domestic abuse allegations – legislative presumptions against custody or unsupervised visitation/contact for abusive parents. The experience of presumptions in the USA and New Zealand suggests that a similar gap between ‘law in the books’ and ‘law in action’ exists, together with potential problems of legislative drafting. Finally, the article outlines the contributions of the other papers in the special issue to our understanding of international approaches to ensuring safety for children and resident parents in family proceedings where allegations of domestic abuse are raised.
