The nature of domestic cattle origins in Africa are unclear as archaeological data are relatively sparse. The earliest domesticates were humpless, or Bos taurus, in morphology and may have shared a common origin with the ancestors of European cattle in the Near East. Alternatively, local strains of the wild ox, the aurochs, may have been adopted by peoples in either continent either before or after cultural influence from the Levant. This study examines mitochondrial DNA displacement loop sequence variation in 90 extant bovines drawn from Africa, Europe, and India. Phylogeny estimation and analysis of molecular variance verify that sequences cluster significantly into continental groups. The Indian Bos indicus samples are most markedly distinct from the others, which is indicative of a B. taurus nature for both European and African ancestors. When a calibration of sequence divergence is performed using comparisons with bison sequences and an estimate of 1 Myr since the Bison/Bos Leptobos common ancestor, estimates of 117-275,000 B.P. and 22-26,000 B.P. are obtained for the separation between Indians and others and between African and European ancestors, respectively. As cattle domestication is thought to have occurred approximately 10,000 B.P., these estimates suggest the domestication of genetically discrete aurochsen strains as the origins of each continental population. Additionally, patterns of variation that are indicative of population expansions (probably associated with the domestication process) are discernible in Africa and Europe. Notably, the genetic signatures of these expansions are clearly younger than the corresponding signature of African/European divergence.

International mobility in search of amenity spaces for long-stay tourism is a growing phenomenon. U.S. citizens have practiced this lifestyle migration for decades to Latin American countries, especially to Mexico. British citizens move to Spain for similar reasons. In this paper we make a comparative analysis of these two international contexts in order to gain greater insight into the diversity and breadth of this type of migration. The study uses quantitative surveys administered at each field site. First, we analyze the phenomenon of U.S. citizens’ mobility to Mazatlán, Mexico. Second, we analize citizens from the United Kingdom residing in El Campello, Spain. In particular we compare their socio-demographic profiles, transnational practices and some patterns of social integration.

In the decade to come, the European Union will embark on two new projects, each destined to transform it in fundamental ways: (i) Eastern enlargement, and (ii) economic and monetary union. Neither of these projects will affect all members equally or in the same way. But Greece will, for two reasons, be affected in a manner qualitatively different to all other member states. First, Greece is the only country physically affected by the Luxembourg Summit's decision to begin accession negotiations with some, but not all, Central and Eastern European applicant countries: as a result of this decision, she will continue, for at least another eight to ten years, to be the only member country not to share a common border with another member state, with all the consequent implications in economic and geostrategic tenns. Second, when the European Council meets in early May to select those member states that are deemed to have met the convergence criteria, it will find that Greece is the only member state falling short of those criteria. This development may create additional difficulties for her economy during the transitional period of derogation. It will also pose new risks to Greece, insofar as she will be absent during the initial-and crucial-years of establishing a common monetary policy.
