Recerca paleontològica als jaciments maastrichtians continentals de l'àrea de Fumanya (Alt Berguedà)

Memòria de la recerca realitzada a Vallcebre durant el 2006. S’ha estudiat el registre fòssil de l'àrea del sinclinal d’aquesta població de vertebrats i paleobotànic, concretament dels materials maastrichtians d'origen continental que hi afloren. S'han realitzat excavacions per recuperar restes òssies de vertebrats (per exemple dinosaures sauròpodes i cocodrils eosuquis) i cartografies d'icnites i rastres de titanosaure i de restes vegetals als megajaciments de Fumanya sud i Mina Esquirol. També s'ha avançat en l'estudi de postes de titanosaure excavades en campanyes d'anys anteriors. El treball realitzat està permeten acumular dades que seran de gran utilitat i rellevança científica per entendre com vivien els darrers dinosaures pirinencs.La recerca del projecte s'està realitzant en col•laboració amb l'Institut Català de Paleontologia, el Departament d'Estratigrafia de la Universitat Autònoma de Barcelona, el Departament d'Estratigrafia, Paleontologia i Geociències Marines de la Universitat de Barcelona i el Departament de Geociències de la Universitat de Rennes (França).

Estudio exploratorio sobre tareas traductoras: informe de la estancia de investigación

Investigación elaborada a partir de una estancia en el Centre de Formation de Traducteurs-Localiseurs, Terminologue et Rédacteurs (CFTTR) de la Université Rennes 2 Haute Bretagne, Francia, entre los meses de abril y julio del 2006. El proyecto constituye la fase exploratoria de la tesis doctoral desarrollada en el Departament de Traducció i d’Interpretació de la Universitat Autònoma de Barcelona en torno a la organización del trabajo en las empresas proveedoras de servicios de traducción e interpretación. Se ha recabado información y opiniones sobre la identificación de tareas desempeñadas en el ámbito laboral de quatro empresas sobre la traducción e interpretación y las tareas ajenas a la actividad traductora. Los resultados obtenidos permiten identificar una gran variedad de tareas próximas a la actividad traductora pero distintas de ella. El estudio exploratorio efectuado ha contribuido a mejorar el diseño de la investigación empírica prevista para la tesis doctoral: aportó información sobre la importancia del enfoque cualitativo, las hipótesis por contrastar, la definición del colectivo, la delimitación formal de las unidades de análisis, y sobre las principales variables de estudio y su medición.

Comparison of recent toll road concession transactions in the United States and France

Recent concessions in France and in the US have resulted in a dramatic difference in the valuation placed on the toll roads; the price paid by the investors in France was twelve times current cash flow whereas investors paid sixty times current cash flow for the U.S. toll roads. In this paper we explore two questions: What accounts for the difference in these multiples, and what are the implications with respect to the public interest. Our analysis illustrates how structural and procedural decisions made by the public owner affect the concession price. Further, the terms of the concession have direct consequences that are enjoyed or borne by the various stakeholders of the toll road.

Comparing population distributions from bin-aggregated sample data: an application to historical height data from France

This paper develops a methodology to estimate the entire population distributions from bin-aggregated sample data. We do this through the estimation of the parameters of mixtures of distributions that allow for maximal parametric flexibility. The statistical approach we develop enables comparisons of the full distributions of height data from potential army conscripts across France's 88 departments for most of the nineteenth century. These comparisons are made by testing for differences-of-means stochastic dominance. Corrections for possible measurement errors are also devised by taking advantage of the richness of the data sets. Our methodology is of interest to researchers working on historical as well as contemporary bin-aggregated or histogram-type data, something that is still widely done since much of the information that is publicly available is in that form, often due to restrictions due to political sensitivity and/or confidentiality concerns.

An ex-post view of inequality of opportunity in France and its regions

This paper proposes an ex-post measure of inequality of opportunity in France and its regions by assessing the inequality between individuals exerting the same effort. To this end, we define a fair income that fulfils ex-post equality of opportunity requirements. Unfairness is measured by an unfair Gini based on the distance between the actual income and the fair income. Our findings reveal that the measures of ex-post inequality of opportunity largely vary across regions, and that this is due to di_erences in reward schemes and in the impact of the non responsibility factors of income. We find that most regions have actual incomes closer to fair incomes than to average income, excepted Ile de France where the actual income looks poorly related to effort variables. Finally, we find that income inequality and inequality of opportunity are positively correlated among regions.

Not the right job but a secure one : over-education and temporary employment in France, Italy and Spain

Resorting to four waves of the European Community Household Panel, this research explores the association between temporary employment and the likelihood of being over-educated. Such an association has been largely ignored by the literature explaining over-education, more inclined to attribute such a mismatch to the system of education. Selecting three similarly standarised and stratified systems of education (France, Italy and Spain) and controlling for many other variables likely to affect over-education, like gender, age, tenure, job change, firm size or sector, the paper demonstrates that such an association between temporary employment and over-education exists. Being a stepping stone towards a more stable and adjusted position in the labour market, holding a temporary employment may be associated to a higher likelihood of being over-educated. Such an association is more likely in Italy and France. Yet, the opposite sign prevails where permanent employment becomes such a valuable asset as to make individuals trade human capital by employment security. This is the case of Spain.

Joint determinants of education enrolment and first birth timing in France and West Germany

We examined the reciprocal influence between educational decisions and the timing of first births, using the Family and Fertility Surveys of France and West Germany. Since these two processes are potentially endogenous, we modelled them jointly, using event history models. We hypothesise that the reciprocal impact of educational and fertility careers, as well as the impact of the common determinants of both processes, are gender specific and context specific.The results show a significant endogeneity for women and men in both countries. This endogeneity is stronger for women than for men, while no substantial differences are found between the two countries. Removing this shared and unobserved heterogeneity, the results show a stronger reciprocal impact between the processes for women than for men. A similar impact of being enrolled in education on first birth in both countries is found, while the effect of the birth (and especially of the pregnancy) of the first child on terminating one’s education appeared to be more marked in West Gernany than in France.
