Entanglement in continuous-variable systems: recent advances and current perspectives
2007
We review the theory of continuous-variable entanglement with special emphasis on foundational aspects, conceptual structures, and mathematical methods. Much attention is devoted to the discussion of separability criteria and entanglement properties of Gaussian states, for their great practical relevance in applications to quantum optics and quantum information, as well as for the very clean framework that they allow for the study of the structure of nonlocal correlations. We give a self-contained introduction to phase-space and symplectic methods in the study of Gaussian states of infinite-dimensional bosonic systems. We review the most important results on the separability and distillabil…
Higher Education Reforms in Finland
2019
Finland has implemented several higher education (HE) reforms over the past decades in order to make its HE system more competitive in the global educational markets. These reforms are in line with the developments in other Western higher education systems in which the transposition of principles and philosophy from the private sector into the public sector has become more common or even a norm thus reinterpreting the economic, social and cultural basis of higher education (e.g. Exworthy & Halford 1999). Furthermore, the implementation of the reforms is a response to the rapidly changing needs of the labour markets. In Finland, Bologna process was partly incorporated to be part of the react…
La escritura medieval de la Corona de Aragón (1137-1474)
2020
In this study, we analyze concisely the evolution of the forms adopted by the script of the Crown of Aragon, from 1137 until 1474. The chronological period analyzed includes the formal variations of the gothic and the humanistic ones. We have not only described the external aspect and the chronology for both of them, but we have also tried to rebuild the different contexts of use of the writing and the formal characteristics that it adopted, as far as the different functionality is concerned. Given that the most studied field is the Royal Cancillería, its documentation forms the leading thread of this article. Moreover, ocher material (epigraphic, phylactery, from books, etc.) will allow u…
Promoting self-employment: Does it create more employment and business activity?
2021
International audience; We assess the economic impact of reforms promoting self-employment in the three countries that have implemented such reforms since the early 2000s: the Netherlands, the United Kingdom and France. To that end, we use an unbalanced cross country-industry dataset of 4,226 observations, including 12 OECD countries and 20 market industries, over the 1995-2016 period. We first observe, using country-level data, that the share of self-employed workers in total employment is quite stable or declines over the period in all countries in our dataset, except in the three countries where large reforms promoting self-employment have been implemented, and only after these reforms. …
Modified post-bifurcation dynamics and routes to chaos from double-Hopf bifurcations in a hyperchaotic system
2012
In order to understand the onset of hyperchaotic behavior recently observed in many systems, we study bifurcations in the modified Chen system leading from simple dynamics into chaotic regimes. In particular, we demonstrate that the existence of only one fixed point of the system in all regions of parameter space implies that this simple point attractor may only be destabilized via a Hopf or double Hopf bifurcation as system parameters are varied. Saddle-node, transcritical and pitchfork bifurcations are precluded. The normal form immediately following double Hopf bifurcations is constructed analytically by the method of multiple scales. Analysis of this generalized double Hopf normal form …
Interaction between extrinsic and intrinsic online review cues: perspectives from cue utilization theory
2023
AbstractWe examine the interaction effects of linguistic style and verification of online reviews in terms of their valence on purchase intention for search and experiential products. We adopt the cue utilization framework to examine the interplay between the extrinsic cues of online reviews—content style (general versus specific), verified purchase (VP) badge (present versus absent), and valence (positive versus negative)—in two product categories—search product (tablet) and experiential product (trip package)—using an experimental design. The findings of the frequentist and Bayesian analyses show that valence supersedes other attributes’ impacts on purchase intention in both product categ…
