La vulgarisation scientifique et les doctorants : mesure de l'engagement, exploration d'effets sur le chercheur

2018

We ask two questions: what are the factors that influence researchers’ public engagement activities (PEA)? And what are the impacts of these activities on the researcher? After presenting a historical overview of PEA, we analyze 20 surveys carried out between 1967 and 2014. We identify some global trends: PEA is generally positively perceived, researcher’s engagement is occasional but robust. Besides those trends some differences appear between studies based on theoretical models and empirical studies: the latter report complaints such as lack of time or lack of recognition, whereas theoretical-based ones challenge these statements.To further explore our two questions, we used two approache…

The reflection coefficient of a flared microstrip line radiating in an infinite parallel-plate waveguide

1993

In this article the reflection coefficient of a tapered microstrip line radiating in an infinite parallel-plate conducting waveguide is calculated. The reflection coefficient at the feed line is evaluated by using the aperture admittance of the horn and the scattering matrix of the continuous taper. The theoretical behavior of the aperture admittance is shown and the reflection coefficient of a microstrip horn radiating in the parallel-plate region of a bootlace lens is measured in order to verify the model. © 1993 John Wiley & sons, Inc.

Faculty professional development within the domains of pedagogical content knowledge in engineering

2013

The purpose of this work is to contribute to reflection on the strategies for faculty professional development that promote a culture of scholarly and systematic innovation in engineering education. This paper presents the results of implementing a professional development proposal for engineering professors based on developing their teaching competencies and discusses their relative effectiveness.

Ethical Entrepreneurship Training. Theoretical Reflection and Case Analysis

2014

Abstract In this paper we first reflect on the theoretical foundation of ethical entrepreneurship training in the field of economy. In this sense, we try to establish briefly the theoretical and historical assumptions of ethical entrepreneurship, especially from a review of the work of Adam Smith, professor of Moral Philosophy and central figure in the birth of the modern economy. We then present a definition of entrepreneurial activity, which is closely linked to a social and ethical dimension of economy and to the internal goods of economic activity. On the basis of these considerations, we propose some objectives of training for ethical entrepreneurship. Finally, we present a case study …

An optimal dimensioning method of a green wall structure for noise pollution reduction

2021

International audience; This paper concern the optimization of a multilayered green wall structure including substrate and foliage in order to reduce as much as possible backward noise reflection and forward transmission from the wall. Each component involved in the wall structure is fully characterized experimentally to get its transfer matrix. Simulation demonstrated that foliage layer superimposed to substrate layer doesn’t affect the transmission losses but contributes greatly to the increase of return losses of the green wall structure. To achieve the best perfor­mances in terms of return and forward losses as well as frequency bandwidth, the methods of optimization are discussed inclu…

The scientific status of qualitative

2009

This work is focused on the Scientific Status of Qualitative. In our opinions, it constitutes the broadest level our work can be organised into, the most general epistemological frame, within which the specific spheres of application and of research take on a more comprehensive meaning and a more correct capacity of explication. The paradigm of complessity represents, in fact, both at theoretical-epistemological and methodological level, a fundamental reference point in tackling the issue of psychology in a more appropriate way. It, starting from a comprehensive analytical review of the paradigm of “classical” science and of the principles and tools of the experimental method (Morin, 1983; …

Polarimetric image augmentation

2021

Robotics applications in urban environments are subject to obstacles that exhibit specular reflections hampering autonomous navigation. On the other hand, these reflections are highly polarized and this extra information can successfully be used to segment the specular areas. In nature, polarized light is obtained by reflection or scattering. Deep Convolutional Neural Networks (DCNNs) have shown excellent segmentation results, but require a significant amount of data to achieve best performances. The lack of data is usually overcomed by using augmentation methods. However, unlike RGB images, polarization images are not only scalar (intensity) images and standard augmentation techniques cann…

Stability of hydrodynamical relativistic planar jets

2004

The effects of relativistic dynamics and thermodynamics in the development of Kelvin-Helmholtz instabilities in planar, relativistic jets along the early phases (namely linear and saturation phases) of evolution has been studied by a combination of linear stability analysis and high-resolution numerical simulations for the most unstable first reflection modes in the temporal approach. Three different values of the jet Lorentz factor (5, 10 and 20) and a few different values of specific internal energy of the jet matter (from 0.08 to $60.0 c^2$) have been considered. Figures illustrating the evolution of the perturbations are also shown.

"You helped me out of that darkness" Children as dialogical partners in the collaborative post-family therapy research interview.

2021

Applying Dialogical Methods for Investigations of Happening of Change (DIHC), this study investigated how children who had been diagnosed with an oppositional defiant or conduct disorder participated in a collaborative post‐therapy research interview and talked about their experiences of family therapy. The results showed that the children participated as dialogical partners talking in genuine, emotional, and reflective ways. Encountered as full‐membership partners, the children also co‐constructed meanings for their sensitive experiences. However, their verbal initiatives and responses appeared in very brief moments and could easily have been missed. The collaborative post‐therapy intervie…
