Ethnocentrism Effects on Consumers’ Behavior during COVID-19 Pandemic
2021
The COVID-19 pandemic has upset everyone’s normal daily activities, generating psychiatric disorders and changing consumers’ preferences. Among others, the agri-food sector has experienced strong changes and, during the lockdown period, Italian consumers modified their purchasing habits in response to the fear and uncertainty generated by the spread of the virus. In order to find out the main consequences of the shock suffered during the period and to understand which factors have affected purchasing choices, an online survey was conducted on 286 Italian consumers. The results show that ethnocentrism has been the factor that most has influenced consumers’ behavior during the lockdown period…
La grotte de l'Eremita au Monte Fenera (Vercelli, Italie) : nouvelles découvertes du Bronze moyen
2014
Située au coeur du massif calcaire du Monte Fenera dans le Piémont italien, la grotte de l'Eremita, appelée également Tana dell'Armittu, fait l'objet d'une intervention archéologique menée par l'Université de Genève (direction M. Besse). Suite à des sondages effectués en 2012 lors desquels furent mises au jour, entre autres, des perles spiralées et une épingle en bronze, une fouille programmée a été organisée dès 2013. Notre contribution présente les données de terrains de l'année 2013. La fouille archéologique s'est déroulée avec les étudiants en archéologie, l'aspect didactique - auquel nous sommes fermement attachés - étant un des objectifs de cette fouille.
Searches for small-scale anisotropies from neutrino point sources with three years of IceCube data
2015
Recently, IceCube found evidence for a diffuse signal of astrophysical neutrinos in an energy range of $60\,\mathrm{TeV}$ to the $\mathrm{PeV}$-scale. The origin of those events, being a key to understanding the origin of cosmic rays, is still an unsolved question. So far, analyses have not succeeded to resolve the diffuse signal into point-like sources. Searches including a maximum-likelihood-ratio test, based on the reconstructed directions and energies of the detected down- and up-going neutrino candidates, were also performed on IceCube data leading to the exclusion of bright point sources. In this paper, we present two methods to search for faint neutrino point sources in three years o…
Search for the Lepton Flavor Violation Process J/ψ→eμ at BESIII
2013
We search for the lepton-flavor-violating decay of the $J/\psi$ into an electron and a muon using $(225.3\pm2.8)\times 10^{6}$ $J/\psi$ events collected with the BESIII detector at the BEPCII collider. Four candidate events are found in the signal region, consistent with background expectations. An upper limit on the branching fraction of $\mathcal{B}(J/\psi \to e\mu)< 1.5 \times 10^{-7}$ (90% C.L.) is obtained.
The effect of education on migration: evidence from school reform
2010
A polytechnic, higher education reform took place in Finland in the 1990s. It gradually transformed former vocational colleges into polytechnics and expanded higher education to all Finnish regions. We implement instrumental variables estimators that exploit the exogenous variation in the regional availability of polytechnic education together with matriculation exam scores. Our IV results show that polytechnic graduates have a higher migration probability than those of vocational college graduates. However, a master’s degree did not increase migration propensity in comparison with a polytechnic degree. We also find that an increase in the availability of polytechnic education did not reduc…
Who turns to entrepreneurship later in life? - Push and pull in Finnish rural and urban areas
2014
Age is an important factor in entrepreneurship. The paths into entrepreneurship at a later age may be varied. Self-employment in later life may be either a form of partial retirement or a career option. Older individuals may also be pushed into self-employment. The focus of this paper is on the career choices of older individuals and their background motivations in Finland. The purpose is to analyse the factors and motives in terms of the push and pull dichotomy that lead individuals to enter self-employment at older ages in different types of labour markets in Finland, viz., rural and urban areas. Although some studies have focused on transitions to self-employment among older workers, que…
The continuous sample of working lives: Improving its representativeness
2017
This paper studies the representativeness of the Continuous Sample of Working Lives (CSWL), a set of anonymized microdata containing information on individuals from Spanish Social Security records. We examine several CSWL waves (2005–2013) and show that it is not representative for the population with a pension income. We then develop a methodology to draw a large dataset from the CSWL that is much more representative of the retired population in terms of pension type, gender and age. This procedure also makes it possible for users to choose between goodness of fit and subsample size. In order to illustrate the practical significance of our methodology, the paper also contains an applicatio…
Satisfacción laboral de los asalariados en España
2012
El objetivo de este trabajo es identificar los factores determinantes del nivel de satisfacción laboral de los asalariados en España, haciendo especial hincapié en las diferencias de género y de nacionalidad. Para ello, se estima un modelo de respuesta múltiple ordenada, utilizando los datos de la Encuesta de Calidad de Vida en el Trabajo, para el período que abarca desde 2006 a 2010. Los resultados obtenidos muestran que, después de controlar por las características personales y laborales de los asalariados, se obtiene un diferencial positivo en la satisfacción laboral en favor de las mujeres, mientras que no se evidencia la existencia de un efecto diferencial entre los asalariados nativos…
The assignment of powers in an open-ended European Union
2003
Presented at CESIFO Conference “A Constitution for the EU”, February 2003; International audience; A major characteristic of the European Union is its transitional or evolving nature, in particular with regard to the assignment of powers between the two main levels of government. More precisely, under current constitutional arrangements, this evolving nature takes the form of an integration process which tends to be monotonous, that is, which can only with great difficulty be reversed. The paper is mainly devoted to the explanation of how this comes about and what effects this has on other features of the process. As a concluding remark, however, it suggests that an additional criterion for…
Dephasing due to quasiparticle tunneling in fluxonium qubits: a phenomenological approach
2015
The fluxonium qubit has arisen as one of the most promising candidate devices for implementing quantum information in superconducting devices, since it is both insensitive to charge noise (like flux qubits) and insensitive to flux noise (like charge qubits). Here, we investigate the stability of the quantum information to quasiparticle tunneling through a Josephson junction. Microscopically, this dephasing is due to the dependence of the quasiparticle transmission probability on the qubit state. We argue that on a phenomenological level the dephasing mechanism can be understood as originating from heat currents, which are flowing in the device due to possible effective temperature gradients…
