Comparison results for Hessian equations via symmetrization
2007
where the λ’s are the eigenvalues of the Hessian matrix D2u of u and Sk is the kth elementary symmetric function. For example, for k = 1, S1(Du) = 1u, while, for k = n, Sn(D 2u) = detD2u. Equations involving these operators, and some more general equations of the form F(λ1, . . . , λn) = f in , (1.2) have been widely studied by many authors, who restrict their considerations to convenient cones of solutions with respect to which the operator in (1.2) is elliptic. Following [25] we define the cone 0k of ellipticity for (1.1) to be the connected component containing the positive cone 0 = {λ ∈ R : λi > 0 ∀i = 1, . . . , n} of the set where Sk is positive. Thus 0k is an open, convex, symmetric…
Validating Test Score Interpretations by Cross-National Comparison
2015
Cross-national assessment of students’ competences in higher education is becoming increasingly important in many disciplines including economics but there are few available instruments that meet psychological standards for assessing students’ economic competence in higher education (HE). One of them is the internationally valid Test of Understanding in College Economics (TUCE), which has been adapted and employed successfully in HE systems in various countries, but the test results have seldom been used for international comparisons of students’ Economic Content Knowledge (ECK). Here, we compare the German and the Japanese test adaptations of the TUCE with reference to the American origin…
Job Satisfaction Determinants of Tertiary Graduates in Europe
2015
Abstract Factors affecting the job satisfaction of tertiary graduates are studied using recent data on 13 European countries from 2010–11. Special attention is given to differences between bachelors and masters. It is found that in many countries, master's degree decreases job satisfaction. Moreover, it never increases the job satisfaction of female employees. Masters are more sensitive than bachelors to career opportunities, variety in work and whether learning is required in the job; while bachelors are more sensitive to the risk of moving to a less interesting job and monetary compensation. Overeducation generally does not affect the job satisfaction of bachelors, but strongly decreases …
Laboratory phase‐contrast nanotomography of unstained Bombus terrestris compound eyes
2021
Imaging the visual systems of bumblebees and other pollinating insects may increase understanding of their dependence on specific habitats and how they will be affected by climate change. Current high-resolution imaging methods are either limited to two dimensions (light- and electron microscopy) or have limited access (synchrotron radiation x-ray tomography). For x-ray imaging, heavy metal stains are often used to increase contrast. Here, we present micron-resolution imaging of compound eyes of buff-tailed bumblebees (Bombus terrestris) using a table-top x-ray nanotomography (nano-CT) system. By propagation-based phase-contrast imaging, the use of stains was avoided and the microanatomy co…
An International Comparison of Skills, Traits and Job Mobility
2019
Making use of an international survey that directly assesses the cognitive skills of the adult population, I document systematic differences in the effect of skills on job mobility across the 37 countries in the sample. While economic growth is associated with relatively higher job mobility among skilled workers, the prevalence of information and communication technology (ICT) in the workplace is associated with relatively lower job mobility. The documented patterns are in line with Schumpeterian growth models of creative destruction in which skilled workers transition to jobs with advanced technologies more easily.
Quelques réflexions sur les remplois antiques en Limousin au cours du Moyen Âge
2011
Different kinds of antique material were re-used in the Limousin region during the middle ages. In this article the authors will mostly focus on the big ashlars located in the ecclesiastical rural sites. More and more of these specific kinds of spolia are now known. Around 50 sites are identified where they were used in churches or in their surroundings (mostly sarcophagi). In most examples only few pieces were used. Nonetheless, in seven cases those blocks are numerous, and in three of them parts of antique buildings - using monumental ashlars - are incorporated into churches. It is highly probable that the spoiled monuments were mausolea. At least two of them were re-used for a Christian …
Neoliberalismo y procesos de privatización 'en' la educación pública en Inglaterra y España
2021
El neoliberalismo desde la década de los 80 ha impactado en las agendas de política educativa tanto nacionales como internacionales con el objetivo de introducir la racionalidad competitiva en el seno de los sistemas educativos. En gran medida, estas políticas introducen mecanismos que ponen a funcionar a los centros educativos bajo formas pedagógicas, de gestión y de gobierno similares a las de una empresa. No en vano, el impacto y profundidad de estas reformas están relacionadas con la historia, contexto, economía y objetivos de los responsables políticos en el poder en un momento dado. Por lo tanto, no podemos hablar de un neoliberalismo, sino de diversos neoliberalismos. En el presente …
Benevolent and corrective humor, life satisfaction, and broad humor dimensions : extending the nomological network of the BenCor across 25 countries
2020
Indexación: Scopus. Benevolent and corrective humor are two comic styles that have been related to virtue, morality, and character strengths. A previous study also supported the viability of measuring these two styles with the BenCor in 22 countries. The present study extends the previous one by including further countries (a total of 25 countries in 29 samples with N = 7813), by testing the revised BenCor (BenCor-R), and by adding two criterion measures to assess life satisfaction and four broad humor dimensions (social fun/entertaining humor, mockery, humor ineptness, and cognitive/reflective humor). As expected, the BenCor-R showed mostly promising psychometric properties (internal consi…
