Timescale-dependent stock market comovement: BRICs vs. developed markets

2014

This paper examines the differences in the asset return comovement of the BRIC countries (Brazil, Russia, India and China), the other developed economies in their regions (Canada, Hong Kong and Australia) and the major industrialized economies (the U.K., Germany and Japan) with respect to the U.S. for different return periods. The novelty of the paper is that the stock return indices are decomposed to several timescales using wavelet analysis and that the results are further used as inputs for the dynamic conditional correlation (DCC) framework, which is used as a measure of comovement. The results propose that the level of stock market comovement depends on regional aspects, the level of d…

Internationalization via strategic alliances in family businesses.

2004

It has been observed in previous studies that certain characteristics of family businesses may impede internationalization. These characteristics include the concentration of decision-making in the hands of a single shareholder or small group of shareholders, delays in the succession process, aversion to internationalization, etc. Despite these obstacles, a large number of family businesses have chosen to internationalize as a means of revitalizing themselves. The results of the study reported here indicate three important pre-requisites for family businesses that are seriously considering internationalization as an aid to growth: they need to have a market-leading product, adequate financi…

Étude de la collaboration interprofessionnelle dans le secteur hospitalier français : le rôle des facteurs organisationnels

2022

In a troubled hospital context subject to many changes and constraints, inter-professional collaboration is a major asset in terms of adaptation, quality of care and managerial innovation. However, its levers remain to be specified and its implementation is complex. A review of the literature and an empirical survey lay the foundation for our research work, which has various objectives. First of all, it seeks to clarify the place of interprofessional collaboration in the hospital sector. Then he seeks to understand the influence of organizational factors on emerging states of collaboration. Finally, it examines how health managers can rely on organizational factors to enable the emergence o…

Integrating xAPI in AR applications for Positive Behaviour Intervention and Support

2021

The spread of new technologies like Augmented Reality and recent technological developments, provide innovative techniques and tools that show increasing potential in education. In this paper we will showcase the work implemented within the Horizon 2020 European project ARETE (Augmented Reality Interactive Educational System). One of the pilots of this project aims to investigate for the first time the introduction of AR to support a behavioral lesson in schools where Positive Behaviour Intervention and Support (PBIS) methodology is adopted. In particular, we present the study conducted to track user interactions with augmented reality objects through the use of the Experience API standard.

Pesticide occurrence in the waters of Júcar River, Spain from different farming landscapes.

2017

A combined methodology to identify and quantify farming chemicals in the entire Júcar River basin has been developed. The procedure consisted of the application of environmental forensic criteria associating laboratory analytical samples, cartographic analysis using Geographical Information Systems (GIS) and synthetic statistical analysis. Sampling involved the collection of 15 samples in surface waters distributed alongside the Júcar River and its two main tributaries (Cabriel and Magro Rivers). The analytical procedure involves generic sample extraction and selective determination of up to 50 target pesticides by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Geogra…

An environmental forensic procedure to analyse anthropogenic pressures of urban origin on surface water of protected coastal agro-environmental wetla…

2013

Detection and spatial distribution of 14 drugs of abuse and 17 pharmaceuticals in surface waters was investigated to determine transport hydrological connectivity between urban, agriculture and natural environments. Solid-phase extraction and liquid chromatography tandem mass spectrometry was applied to all samples. To determine spatial incidence of contaminants, analytical results of target compounds were georeferenced and integrated into a geographical information systems structure together with layers of municipal population, location of sewage water treatment plants and irrigation channels and sectors. The methodology was applied to L'Albufera Natural Park in Valencia (Spain). A total o…

Cavity optomechanics mediated by a quantum two-level system

2015

Coupling electromagnetic waves in a cavity and mechanical vibrations via the radiation pressure of photons is a promising platform for investigations of quantum–mechanical properties of motion. A drawback is that the effect of one photon tends to be tiny, and hence one of the pressing challenges is to substantially increase the interaction strength. A novel scenario is to introduce into the setup a quantum two-level system (qubit), which, besides strengthening the coupling, allows for rich physics via strongly enhanced nonlinearities. Here we present a design of cavity optomechanics in the microwave frequency regime involving a Josephson junction qubit. We demonstrate boosting of the radiat…

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…

Interaction-free measurements with superconducting qubits

2008

An interaction-free measurement protocol is described for a quantum circuit consisting of a superconducting qubit and a read-out Josephson junction. By measuring the state of the qubit one can ascertain the presence of a current pulse through the circuit at a previous time without any energy exchange between the qubit and the pulse.
