Enhancing the SCIROCCO tool using quantitative and qualitative methods
2018
Background: The SCIROCCO tool, developed as part of the SCIROCCO project, incorporates the Maturity Model for the adoption of Integrated Care developed by the European Innovation Partnership on Active and Healthy Ageing (B3 Action Group on Integrated Care). The online self-assessment tool can be used to facilitate scaling-up of integrated care across different health and care sectors, at different levels in health or care systems, and in a range of communities. Currently, more than 30 European regions are involved in testing the SCIROCCO tool. Since the project launch in April 2016, the tool underwent two iterations. Each of the iterations of the tool was followed by a round of refinement t…
A PHENOMENOLOGICAL OPERATOR DESCRIPTION OF INTERACTIONS BETWEEN POPULATIONS WITH APPLICATIONS TO MIGRATION
2013
We adopt an operatorial method based on the so-called creation, annihilation and number operators in the description of different systems in which two populations interact and move in a two-dimensional region. In particular, we discuss diffusion processes modeled by a quadratic hamiltonian. This general procedure will be adopted, in particular, in the description of migration phenomena. With respect to our previous analogous results, we use here fermionic operators since they automatically implement an upper bound for the population densities.
Topics on n-ary algebras
2011
We describe the basic properties of two n-ary algebras, the Generalized Lie Algebras (GLAs) and, particularly, the Filippov (or n-Lie) algebras (FAs), and comment on their n-ary Poisson counterparts, the Generalized Poisson (GP) and Nambu-Poisson (N-P) structures. We describe the Filippov algebra cohomology relevant for the central extensions and infinitesimal deformations of FAs. It is seen that semisimple FAs do not admit central extensions and, moreover, that they are rigid. This extends the familiar Whitehead's lemma to all $n\geq 2$ FAs, n=2 being the standard Lie algebra case. When the n-bracket of the FAs is no longer required to be fully skewsymmetric one is led to the n-Leibniz (or…
Vibrational modes of the stibine molecule
2005
International audience; In this paper, we use the algebraic approach to describe the vibrational modes of stibine molecule (of C3v molecular symmetry group) up to 21 quanta. As the stibine molecule exhibits stretch-bend resonances, we build an algebraic pyramidal coupling operator between stretching modes and bending modes adapted to this molecule. The standard deviation associated to the fit of the vibrational levels is 1.75 cm-1.
Design Features for Gender-specific Differences in Blended Learning within Higher Education in Indonesia
2019
Blended learning offers learning solutions for higher educational institutions facing the industrial revolution 4.0. In this study, we investigated the influence factors student perceptions of blended learning based on gender-specific differences in Indonesia. We applied a research model to systematically assess the effect of design features on the effectiveness of blended learning indicators (intrinsic motivation and student satisfaction). Moreover, we evaluated the research model for both genders separately. Based on the quantitative survey of 223 Indonesian students, our study confirms that the design features significantly influence the effectiveness of blended learning for male and fem…

Du monnayage au crypto-monnayage
2020
Minting Techniques in Currencies and Cryptocurrencies. Over the past ten years, the creation of bitcoin and other cryptocurrencies has renewed the debate on the nature of money. This paper discusses the comparison between cryptocurrencies and coins : after describing their ideological and technical foundations, we explain the reasons why the reference to metals is often invoked. We then detail the techniques of minting, the processes of marking, and the question of seigniorage.
Quantitative methods in business history: An impossible equation?
2010
Abstract In this article we want to evaluate how often quantitative tools and methods were utilized in the two premier journals in business history in the 1990s. Thus we tap into an important methodological discussion among the post-Chandlerian business historians. We found that simpler quantitative tools were employed quite often, but not necessarily going much beyond that.Also, it became apparent that the most cited business history articles were often written by scholars coming from‘outside’ the fluid disciplinary core of business history field.The analyses performed in the article revealed that the level of quantification seemed to have either no discernible impact (Business History Rev…
Different approaches to research and innovation in physics education at college and university
2019
Abstract In this article we report a Symposium organized by GTG-Physics Education Research at University (PERU) with different proposals that includes innovative educational approaches and research on problems of teaching-learning physics at university. In the second section, two research projects are described on teaching specific curriculum topics that present special difficulties for students. In the next section the third project on a work experience in the laboratory that takes into account the characteristics of scientific work, is presented. Finally, the fourth project presents a way to investigate the types of student reasoning. In the discussion, the importance of research projects…
Ancient human genomes suggest three ancestral populations for present-day Europeans
2014
We sequenced the genomes of a ∼7,000-year-old farmer from Germany and eight ∼8,000-year-old hunter-gatherers from Luxembourg and Sweden. We analysed these and other ancient genomes1,2,3,4 with 2,345 contemporary humans to show that most present-day Europeans derive from at least three highly differentiated populations: west European hunter-gatherers, who contributed ancestry to all Europeans but not to Near Easterners; ancient north Eurasians related to Upper Palaeolithic Siberians3, who contributed to both Europeans and Near Easterners; and early European farmers, who were mainly of Near Eastern origin but also harboured west European hunter-gatherer related ancestry. We model these popula…
