The gaps of nations & the rise of far-right populism
The Brexit vote and more recently the US presidential election suggest a noticeable rise of populism. Marion Laboure and Juergen Braunstein argue that this trend is not new. For example, Austrian Chancelor Schuessel’s invitation to the far-right freedom party to form a government in 1999/2000 caused upheaval in Europe, and beyond. Shortly after, during the French presidential elections in 2002, the far-right candidate Le Pen managed to gain enough votes to make it to the second round
The great stagnation
The recent Brexit vote, as well as high uncertainty around a number of upcoming elections (e.g., the 2016 US and 2017 French presidential elections), are only symptoms of a larger underlying problem. Voting for populist and extremist campaigns is a mean of expressing discontent with the status quo, but with far reaching implications. We believe there is a critical urgency to refocus the debate back to the structural drivers behind this international phenomenon
Windfall revenues in Europe: What’s next?
European countries need to start thinking of what to do with windfall tax revenues from multinationals. We argue that there is a need to create a structure addressing the risks relating to potential windfall tax revenues. One solution could be the creation of sovereign venture funds
A New High-Current Large-Bandwidth DC Active Current Probe for Power Electronics Measurements
International audienceThis paper is focused on the design and the realization of two high-current probes (up to 100 A) whose bandwidths range from dc to 50 MHz. The performance has been met by the association of an active Hall sensor and a passive current transformer. This association will be named an "active current transformer." It will be shown that it has better frequency performance than the classical closed-loop current transducer, usually used for high-current measurements but frequency limited. The electromagnetic interference (EMI) issues, due to the sensor electrical environment are respected thanks to the shielded structure and special inner arrangements of the Hall sensors. Because of its large bandwidth, its large current range, and its EMI ruggedness, this current probe is well matched to power electronics measurements. Index Terms-Current probe, current transformer, electromagnetic interference (EMI), Hall sensor, power electronics
Vertical Integration and its Impact on Market Orientation
This research intends to understand the impact of vertical integrations on market orientation and will be illustrated by a case study: the acquisition of a food factory by a major player in the food industry. Research on vertical integration has mainly been focused on its measures and transaction costs issues rather than its effectiveness as a strategy. Research on market orientation has mainly been focused on the implementation of the concept. It is hence interesting to try and fill the gap in the literature by researching on market orientation and how it can be affected by vertical integration. It will give an insight on the implications on customers of integrating additional offerings (e.g. increased value), as well as the implications on performance of combining both vertical integration and market orientation.
Qualitative methods are undertaken to research on the topic, with an emphasis on case study. Face-to-face and electronic interviews with a sample of managers and employees from a food industry company, which has undertaken a vertical integration, have been conducted and from which several conclusions have been drowned. Vertical integrations may contribute for a better market orientation, hence for a better experience on the level of response to the identified needs, thus enabling for better customer satisfaction. Performance is thus achieved thanks to a strong organizational culture and top management’s and employees’ behaviour and attitude. A combination of both vertical integration and market orientation also enables an increase in innovativeness, as well as new knowledge development, and new insights on consumers/customers
Improved Fully-Implicit Spherical Harmonics Methods for First and Second Order Forms of the Transport Equation Using Galerkin Finite Element
In this dissertation, we focus on solving the linear Boltzmann equation -- or transport equation -- using spherical harmonics (PN) expansions with fully-implicit time-integration schemes and Galerkin Finite Element spatial discretizations within the Multiphysics Object Oriented Simulation Environment (MOOSE) framework.
The presentation is composed of two main ensembles.
On one hand, we study the first-order form of the transport equation in the context of Thermal Radiation Transport (TRT). This nonlinear application physically necessitates to maintain a positive material temperature while the PN approximation tends to create oscillations and negativity in the solution. To mitigate these flaws, we provide a fully-implicit implementation of the Filtered PN (FPN) method and investigate local filtering strategies. After analyzing its effect on the conditioning of the system and showing that it improves the convergence properties of the iterative solver, we numerically investigate the error estimates derived in the linear setting and observe that they hold in the non-linear case. Then, we illustrate the benefits of the method on a standard test problem and compare it with implicit Monte Carlo (IMC) simulations.
On the other hand, we focus on second-order forms of the transport equation for neutronics applications. We mostly consider the Self-Adjoint Angular Flux (SAAF) and Least-Squares (LS) formulations, the former being globally conservative but void incompatible and the latter having -- in all generality -- the opposite properties. We study the relationship between these two methods based on the weakly-imposed LS boundary conditions. Equivalences between various parity-based PN methods are also established, in particular showing that second-order filters are not an appropriate fix to retrieve void compatibility. The importance of global conservation is highlighted on a heterogeneous multigroup k-eigenvalue test problem.
Based on these considerations, we propose a new method that is both globally conservative and compatible with voids. The main idea is to solve the LS form in the void regions and the SAAF form elsewhere. For the LS form to be conservative in void, a non-symmetric fix is required, yielding the Conservative LS (CLS) formulation. From there, a hybrid SAAF-- CLS method can be derived, having the desired properties. We also show how to extend it to near-void regions and time-dependent problems. While such a second-order form already existed for discrete-ordinates (SN) discretizations (Wang et al. 2014), we believe that this method is the first of its kind, being well-suited to both SN and PN discretizations

During the early childhood education level (0-6 years) English is used as a semi-introduction to everyday language to introduce basic things to children such as colors, numbers, shape, and other daily habits such as shaking hands and washing hands. This is the purpose of providing English education as early as possible. The impact that arises because learning a second language is given from a young age, among others, makes language acquisition in children increase. LAD (Language Acquisition Device) or the ability to acquire language is an innate ability possessed by every human being or as a language device acquired by children from birth will become more active so as to improve children''s language acquisition.
