Structural, vibrational and electrical study of compressed BiTeBr

2016

Compresed BiTeBr has been studied from a joint experimental and theoretical perspective. Room-temperature x-ray diffraction, Raman scattering, and transport measurements at high pressures have been performed in this layered semiconductor and interpreted with the help of ab initio calculations. A reversible first-order phase transition has been observed above 6–7 GPa, but changes in structural, vibrational, and electrical properties have also been noted near 2 GPa. Structural and vibrational changes are likely due to the hardening of interlayer forces rather than to a second-order isostructural phase transition while electrical changes are mainly attributed to changes in the electron mobilit…

Caracterización de las áreas urbanas gallegas en función de los flujos de movilidad obligada

2010

La realidad territorial en los municipios gallegos evolucionó a ritmos dispares, afectados por dinámicas muy diferentes en cada uno de los casos. Los problemas en la aplicación de la normativa urbanística y de los instrumentos técnicos para la gestión del suelo gestaron unos ámbitos urbanos desconectados de su realidad metropolitana. Las áreas de influencia en las ciudades de Galicia presentan modelos complejos, adaptados a las dificultades que les privaron de una gestión prudente y coherente de los nuevos territorios urbanos. En la evaluación de la nueva realidad urbana, de sus condiciones y características, la movilidad residencial y la recurrente diaria es un elemento de primer rango de …

Impact of wage penalty on mobility return of French PhDs

2015

International audience; Expatriation of higher-education graduates raises much concern in many countries often in conjunction with talk about the brain drain. It supposedly entails a risk of losing the skills required for a competitive economy. The issue is all the more acute for PhD graduates, who are expected to play a major part in the knowledge economy. However, questions arise as to the causes of such mobility and its consequences for young graduates' individual career paths.

Crystal Structure and Local Dynamics in Tetrahedral Proton-Conducting La1-xBa1+xGaO4

2010

La1-xBa1+xGaO4-0 (LBG) compounds, based on unconnected GaO4 moieties, were recently proposed as proton conductors. Protonic defects in the lattice are inserted through self-doping with Ba2+, to create oxygen vacancies subsequently filled by hydroxyl ions. We present a combined structural analysis on self-doped LBG using X-ray diffraction (XRD) and X-ray absorption (EXAFS): these results unravel the finer structural details on the short-range and long-range scales, and they are correlated with the dynamical properties of protonic conduction coming from vibrational spectroscopy. The structure of the GaO4 groups is independent of the oxide composition. On hydration, an array of short intertetr…

The Effects of Taxation on Migration: Some Evidence for the ASEAN and APEC Economies

2010

This paper investigates the effects of taxation on migration. It develops a stylized, two-country model to examine the impact of taxes on labor mobility. The theoretical predictions that taxes affect migration decisions and that educated workers are more responsive to taxation are supported by some empirical evidence for the economies of the Association of Southeast Asian Nations and the Asia-Pacific Economic Cooperation. The empirical application also shows that average tax rates have a larger impact on migration choices than marginal rates. Average tax rates are most important for migrants with secondary education, while marginal rates have a greater influence on the decisions of migrants…

Rising Educational Attainment and Opportunity Equalization: Evidence from France

2020

Educational policies are widely recognized as the means par excellence to equalize opportunities among children with different social and family backgrounds and to promote intergenerational mobility. In this chapter, we focus on the French case and we apply the opportunity equalization criterion proposed by Andreoli, Havnes, and Lefranc (2019) for evaluating the effect of rising compulsory schooling requirements in secondary education. Our results show that such education expansion has a limited redistributive effect on students’ earnings distribution. Nonetheless, we provide evidence of opportunity equalization among groups of students defined by family background circumstances.

Pathways fostering mobility to higher education for vulnerable immigrants in France, Switzerland and Canada

2016

In this article we wish to clarify not only if, but also how – through which institutional settings – higher education is accessed by students from vulnerable immigrant groups in France, Switzerland and Canada. We are interested in the possible educational mobility that immigrant youths can experience arising from country-specific educational policies designed to increase the enrolment in higher education, particularly the flow from upper-secondary vocational educational tracks to higher education ones. We analyse using panel data in each country the accessibility of different pathways to higher education while taking into account the characteristics of the students. In terms of educational…

Managing Academic Internationalization: A Culture-Based Approach

2014

Abstract The goal of the present paper is apply the blue-ocean strategy to the current status of the higher education system, with a major focus on managing cultural diversity in a global world. Universities nowadays represent poles of excellence in terms of cultural innovation, knowledge creation and transfer to the industry, an interface between home and host country as regards academic mobility (teaching and research mobility); they have a significant role in promoting cultural values and informed intercultural communication, creating academic consortia as well as interacting with the local and business communities. The paper shall also redefine: the role of university managers in the co…

Romanian Households Dealing with Precariousness: A life-course approach

2016

This paper addresses the main pathways through which households avoid slipping into poverty in Romania by employing a life-course approach. Recent researches on social stratification found that in every country we can delineate a particular social layer composed of households living just above the poverty threshold, whose members struggle to reach a more secure prosperity while facing constant threats of downward mobility. Drawing on recent precarious prosperity research, and based on in-depth interviews carried out in 2013 with 25 households situated in between poverty and prosperity from a Romanian city (Cluj-Napoca), we use a life-course approach in order to account for the main routes i…

Higher Education in El Salvador: Pertinence and Education for Entrepreneurship

2015

The training of human resources is crucial for the economic and social development of territories that are striving to become knowledge-based economies. Although the number of student enrolments in El Salvador has increased in recent years, some elements of the higher education system have hindered the country’s development from this approach. El Salvador’s population is generally poorly qualified and particularly poorly specialized. In addition, El Salvador has a low-quality higher education system, which employs poorly qualified teaching staff with outdated methods and syllabuses. The lack of pertinence of the higher education system in El Salvador is reflected in the conflict between the…
