Reply to Douka et al: Critical evaluation of the Ksâr 'Akil chronologies

2015

Our paper (1) proposes a new chronology for Ksâr 'Akil based on 16 accelerator mass spectrometry (AMS) determinations on shells. To minimize the possibility of dating diagenetically compromised samples, we conducted amino acid racemization analyses on the intracrystalline proteins, oxygen isotope analysis, and geochemical characterization of all dated shells. Our calibrated radiocarbon ages fit well with existing Levantine chronologies, but are up to 4,000 y older than Douka et al.’s (2). Our paper explores several possibilities for this difference, whereas Douka et al. (3) provide alternative explanations. They accept our radiocarbon ages as correct but question our sample selection and Ba…

HUMAN PEOPLING OF SICILY DURING QUATERNARY

2015

ABSTRACT The early human peopling of Sicily and Western Mediterranean shores is one of the debated topic in the archaeological and anthropological literature over the twentieth century. This discussion involves not only the specific issue of the peopling of the continental island, but fundamentally the reconstruction of human migration routes and dispersals across the Mediterranean area during Early and Middle Pleistocene. Even if the common route of faunal and human movement is considered from North, and relative to the Messina strait crossing, several authors, on the base of archaeological evidences, hypothesized an early peopling and an African provenance through the Sicilian Channel. Th…

A network analysis of student mobility patterns from high school to master’s

2021

Human migration involves the movement of people from one place to another. An example of undirected migration is Italian student mobility where students move from the South to the Center-North. This kind of mobility has become of general interest, and this work explores student mobility from Sicily towards universities outside the island. The data used in this paper regards six cohorts of students, from 2008/09 to 2013/14. In particular, our goal is to study the 3-step migration path: the area of origin (Sicilian provinces), the regional university for the bachelor’s degree, and the regional university for the master’s. Our analysis is conducted by building a multipartite network with four …

The contribution of human migration to tourism: The VFR travel between the EU28 member states

2017

This study explores the correlation between human migration and that part of tourism due to people visiting friends and relatives in a foreign country. We first compared the network structure of migration stocks and tourism flows between the 28 member countries of the European Union over the period 2000–2012. Then, we performed several econometric analyses to study the main tourism determinants and the correlations between migration to tourism. The paper derives from the discussion of the results an estimate of the contribution to the overall tourism phenomenon due to visiting friends and relatives. Complex network analysis and gravity models were the investigation methods preferred.

La genètica de les migracions humanes: Seguint el rastre de les migracions a través del nostre genoma

2014

La reconstruccio de les migracions humanes es possible gracies a la informacio aportada per diverses disciplines. L’estudi de la diversitat genetica de les poblacions humanes actuals ens revela quins han estat els esdeveniments demografics i moviments migratoris passats que han deixat una empremta en el nostre genoma. El coneixement dels moviments migratoris en temps prehistorics ens permet comprovar hipotesis proposades des d’altres disciplines cientifiques. De la mateixa manera, la distribucio de la diversitat genetica en el futur dependra, en gran part, de les intenses migracions humanes actuals facilitades pels avencos tecnologics.

Fertility, Family, and Human Migrations

2019

The aim of this course is to introduce students to the relationship between demographic change, economic growth, and human well-being. Nothing is more fundamental to our experience whether as individuals, as family members and in society, as death, birth, and our physical place in the world. While those basic features of human life have remained a constant feature of our existence, the nature of the economic and social forces that determine the character of these interactions have changed considerably over time. The topics covered in the course illustrate examples of how human societies have wrestled with demographic problems both in history and at present. We study these topics through an …
