HUMAN RESOURCE PRACTICES IN THE EURO-MEDITERRANEAN REGION: TYPOLOGY
Under the project “Agora RH”, we would like to propose a framework for the analysis of Human Resource practices in the Euro-Mediterranean region. This article is theoretical; it is a reflection of the state of the art and thoughts which led to the construction of a framework for analysis, used for an empirical investigation currently being carried out in the eight countries involved in this project (France, Spain, Italy, Portugal, Morocco, Algeria, Tunisia, and Slovenia). In this article, we will attempt to define key concepts about the evolution of the HR function. We propose in a forthcoming article to expand on our work, presenting the theoretical foundations with particular emphasis on the possible cultural variables.human resources management, human resource function
FOR A SOCIO-ECOLOGICAL TRANSITION: 21ST CENTURY ORGANISATIONS REALIGN THEMSELVES AROUND VALUES
The aim of this paper is to discus the changes that confronting our society. The modernity is perceived like an expression of man's control over himself and over nature through reason in a desire for unlimited expansion, therefore implying that growth could be infinite. Consequently, the new logics of the 21st century concern the globalisation of trade and the issues of sustainable development and social responsibility.modernity, socio-ecological transition, motivation
P4-compatible High-level Synthesis of Low Latency 100 Gb/s Streaming Packet Parsers in FPGAs
Packet parsing is a key step in SDN-aware devices. Packet parsers in SDN
networks need to be both reconfigurable and fast, to support the evolving
network protocols and the increasing multi-gigabit data rates. The combination
of packet processing languages with FPGAs seems to be the perfect match for
these requirements. In this work, we develop an open-source FPGA-based
configurable architecture for arbitrary packet parsing to be used in SDN
networks. We generate low latency and high-speed streaming packet parsers
directly from a packet processing program. Our architecture is pipelined and
entirely modeled using templated C++ classes. The pipeline layout is derived
from a parser graph that corresponds a P4 code after a series of graph
transformation rounds. The RTL code is generated from the C++ description using
Xilinx Vivado HLS and synthesized with Xilinx Vivado. Our architecture achieves
100 Gb/s data rate in a Xilinx Virtex-7 FPGA while reducing the latency by 45%
and the LUT usage by 40% compared to the state-of-the-art.Comment: Accepted for publication at the 26th ACM/SIGDA International

The influence of power and frequency on the filamentary behavior of a flowing DBD-application to the splitting of CO2
In this experimental study, a flowing dielectric barrier discharge operating
at atmospheric pressure is used for the splitting of CO2 into O2 and CO. The
influence of the applied frequency and plasma power on the microdischarge
properties is investigated to understand their role on the CO2 conversion.
Electrical measurements are carried out to explain the conversion trends and to
characterize the microdischarges through their number, their lifetime, their
intensity and the induced electrical charge. Their influence on the gas and
electrode temperatures is also evidenced through optical emission spectroscopy
and infrared imaging. It is shown that, in our configuration, the conversion
depends mostly on the charge delivered in the plasma and not on the effective
plasma voltage when the applied power is modified. Similarly, at constant total
current, a better conversion is observed at low frequencies, where a less
filamentary discharge regime with a higher effective plasma voltage than that
at a higher frequency is obtained
Injection moulding of fibre reinforced thermoplastics: integration of fibre orientation and mechanical properties computations
International audienceInjection moulding is widely used to process short fibre reinforced thermoplastics. The quality and especially the mechanical properties of the resulting part are linked to the mould conception (for example the gate(s) and the venting port(s) locations) and to the processing parameters which will govern fibre orientation distribution. Fibre orientation modelling is based on the well known Folgar and Tucker equation which differ one from another by the interaction parameter, the closure approximation and by the coupling with the rheology of the reinforced melt. Quantitative comparison with experiments is very tedious and generally limited to simple part geometries (plaque or disk). As a consequence, in complex geometries, fibre orientation distribution is experimentally checked using several techniques and the resulting anisotropic thermomechanical properties are computed using various homogenization theories. In this paper, we propose an integrated approach of the injection moulding of fibre reinforced thermoplastics starting from rheology of the material, orientation equation, interaction parameter and closure approximation. The resulting local fibre orientation distribution is then used in two ways in order to predict the mechanical properties of the part: First, using classical analytical homogenization theories but based on the computed orientation tensor and not on an experimental one, then, using numerical homogenization which consists in generating a Representative Elementary Volume (REV), by determining its unidirectional mechanical properties and finally, in computing directly the anisotropic properties of the part
