Human capital and RD Driven Growth: analyse for France at regional level on the long run
2012
At the root of the Lisbon goal, for Europe, is placed the awareness for advocating a close link between growth and dissemination of advanced knowledge and innovation, on the one hand, and raising in general endowments in human capital, on the other hand, as to have power over the development of non-specific skills and boost efficiency. Much work in literature also stressed the interest of the position concerning traditional activities in the geography of innovation and links, in the long term, between the spatial distribution of longestablished skills and knowledge creation. Following Jones, in this approach, for which contribution to R&D and innovation explains half of the increase in weal…
Capital humain et croissance : l'apport des enquêtes internationales sur les acquis des élèves
2006
The estimation of the relationship between education and economic growth is marked by contradictions. These contradictions underline the lack of precision characterising indicators of human capital. This paper constructs new indicators based on a pool of international surveys concerning pupil assessment. Thus, our new database, which includes 105 countries, makes it possible to confirm or not the positive relationship between education and growth. Taking into account the endogeneity of education, we measure a positive effect of qualitative indicators of human capital and the growth of countries between 1960 and 2000. The contribution of education to growth therefore appears significant,…
Economic Returns to Education in France: OLS and Instrumental Variable Estimations
2013
En ligne sur : http://121.52.153.179/JOURNAL/LJE%20VOL%2018-2/Bhatti,%20Bourdon%20and%20Aslam.pdf; International audience; This article estimates the economic returns to schooling as well as analyzing other explanatory factors for the French labor market. It addresses the issue of endogeneity bias and proposes two new instruments for use in the instrumental variable two-stage least squares technique. Our results show that the proposed instruments are relevant and adequate, based on evidence from the available literature. After using the proposed instruments, we find that the OLS coefficients for schooling are biased downwards. Finally, we choose between the two proposed instruments.
Rebuilding a Cluster while protecting knowledge within Low-medium-tech supplier SMEs: A Spanish and French comparison
2021
International audience; Most of SMEs are engaged in open innovation practices, but they do not benefit from open innovation or from patenting in the same way as larger firms do. At the same time SMEs, as territorialized suppliers, play a crucial role within evolving regional specialization. In this context the purpose of our study is to examine how low and medium technology supplier SMEs learn and organize themselves at a territorial level to address the challenge of IP protection in an open innovation paradigm. We used a qualitative method with a longitudinal multi-case study involving 27 companies with a historical lance to compare the territorial dynamics of knowledge protection within c…
Study of parameters endogeneous and exogeneous to ordinary Portland ciment influencing hydration of its main phase : tricalcium silicate
2012
This work devoted to study various parameters influencing hydration of silicate phase main Ordinary Portland Cement (OPC) was performed at the Laboratoire Interdisciplinaire Carnot de Bourgogne (ICB). This study is part of the project "Crystal Growth Control" initiated by BASF in order to monitor and provide the best as possible the hydration of Ordinary Portland Cement. The dissolution of alite, like the pure C3S one, is fast in pure water. Speed decreases with deviation from equilibrium and the concentration of aluminates ions in solution. There is also an adsorption on the surface of the aluminum which is into the alite and released by dissolution. Germination and growth of C-S-H has bee…
P-Type Doping of 4H-SiC for Integrated Bipolar and Unipolar Devices
2015
International audience; P-type 4H-SiC layers formed by ion implantation need high temperature processes, which generate surface roughness, losing and incomplete activation of dopants. Due to dopant redistribution and channeling effect, it is difficult to predict the depth of the formed junctions. Vapor-Liquid-Solid (VLS) selective epitaxy is an alternative method to obtain locally highly doped p-type layers in the 1020 cm-3 range or more. The depth of this p-type layers or regions is accurately controlled by the initial Reactive-Ion-Etching (RIE) of the SiC. Lateral Junction Field Effect Transistor (JFET) devices are fabricated by integrating p-type layers created by Al ion implantation or …

Territori dell'abusivismo: Agrigento e il suo hinterland
2017
In Sicilia, le pesanti ricadute dell’abusivismo edilizio sulla qualità del paesaggio, sul corretto sviluppo urbanistico, sull’economia e sulla sicurezza del territorio, hanno ormai compromesso, solitamente in maniera irreversibile, l’immagine di diversi centri urbani e di interi tratti di costa. In quest’ottica Agrigento e il suo hinterland costituiscono un esempio emblematico in cui il dilagare dell’abusivismo edilizio è espressione di un malcostume diffuso, rimasto per anni impunito. Il fenomeno dell’abusivismo nel territorio agrigentino investe, senza eccezione alcuna, tutti i centri urbani gravitanti attorno al capoluogo, anche se in maniera differenziata. Le maggiori percentuali di edi…
Simulations on the mechanism of CNT bundle growth upon smooth and nanostructured Ni as well as θ-Al2O3 catalysts
2011
Abstract In the current study, we have performed ab initio DFT calculations on the gradually growing 2D periodic models of capped single-wall carbon nanotubes (SW CNTs) upon their perpendicular junctions with the Ni(111) substrate, in order to understand the peculiarities of the initial stage of their growth on either smooth or nanostructured catalytic particles. Appearance of the adsorbed carbon atoms upon the substrate follows from the dissociation of CVD hydrocarbon molecules, e.g., CH4: (CH4)ads → (CH)ads+3Hads and (CH)ads → Cads+Hads. (Since the effective growth of CNTs upon Ni nanoparticles occur inside the nanopores of amorphous alumina, we have also simulated analogous surface react…
