Les trois C de la performance sociétale organisationnelle : convention, compromis, cohérence
Résumé
L’intérêt grandissant au sujet de l’existence d’une responsabilité et d’une performance sociétale organisationnelle qui incomberaient à l’entreprise a donné naissance à un champ de recherche articulé autour de deux pôles : la responsabilité et la performance sociétale de l’organisation ainsi que le modèle des parties prenantes. Plusieurs recherches dans ce domaine indiquent que le gestionnaire a un rôle de mandataire des autres parties dont il doit défendre les intérêts tout en préservant l’équilibre entre leurs multiples demandes. L’étude du cas de la compagnie Alcan et de sa relation avec la collectivité régionale du Saguenay – Lac-Saint-Jean permet d’apporter un éclairage différent sur la gestion de la performance sociétale organisationnelle dans une arène de gouvernance délimitée par les parties prenantes. Ce cas nous apprend qu’il est possible de gérer les relations entre l’entreprise et la collectivité en agissant en fonction des trois C de la performance sociétale organisationnelle, soit une convention qui se négocie, se construit socialement, un compromis sur chacune des catégories (principes, mécanismes, résultats) de la performance sociétale organisationnelle et, surtout, la cohérence de l’alignement des catégories
A note on the third family of N=2 supersymmetric KdV hierarchies
We propose a hamiltonian formulation of the supersymmetric KP type
hierarchy recently studied by Krivonos and Sorin. We obtain a quadratic
hamiltonian structure which allows for several reductions of the KP type
hierarchy. In particular, the third family of KdV hierarchies is
recovered. We also give an easy construction of Wronskian solutions of the KP
and KdV type equations
Las prácticas de responsabilidad social empresarial en las pequeñas y medianas empresas en Jalisco y Quebec: ¿Isomorfismo después del TLCAN? = The corporate social responsibility practices in small and medium enterprises in Jalisco and Quebec: isomorphism after NAFTA?
Resumen
El objetivo de este trabajo es cotejar la presencia de un efecto de convergencia e isomorfismo en prácticas de Responsabilidad Social Empresarial (RSE), desde lo predicho por la teoría neoinstitucionalista en PYMEs. de Jalisco, México y de Quebec, Canadá. Ambos sometidos a las mismas reglas institucionales surgidas del TLCAN. El método se basó sobre el análisis de 200 PYME localizadas en Quebec y 200 en Jalisco. Se hicieron pruebas ANOVA, sobre un instrumento de desarrollo propio, para corroborar si hay similitudes isomorfas o no de cada variable analizada. Los resultados tienden a demostrar que las PYME de Jalisco son similares a las de Quebec sobre prácticas de RSE. Por lo que se concluye, como primeros hallazgos, que las hipótesis planteadas constituyen unas simplificaciones restrictivas de la realidad para comprender el fenómeno de la influencia de los tratados entre ambos países sobre las prácticas de RSE en las PYME de cada país.
Abstract
The objective of this study is to check y if there is an isomorphic and convergence effect on CSR practices predicted by neo-institutionalist theory in SMEs in Jalisco, Mexico and Quebec, Canada. Both summited to the same institutional rules arising from NAFTA. The methodology was based on 200 SMEs located at Quebec and 200 at Jalisco. ANOVA tests were performed, on an instrument of own development, to corroborate whether there are isomorphic similarities or not of each variable analyzed. The results tend to show that SMEs in Jalisco are similar to those of Quebec on CSR practices. It is concluded, as findings, that the hypotheses presented are simplifications restricting reality to understand the phenomenon of the influence of treaties between the two countries on CSR practices in SMEs in each country
"Stakepartner management" in projects: A turn-of-the-century turnaround at Alcan
The ideas behind project management have changed significantly since the 1980s. Traditionally based around engineering principles, project management is now primarily focused on creating value jor various groups of stakeholders (SH). In turn, an integral part of stakeholder management moved from a basically contractual approach to a communication focused, or public relations, approach before recently evolving yet again to a partnership approach. The aim of this article is to illustrate the move towards partnership management of stakeholders and to use a case study to discuss the consequences of such a move on management and leadership. The case study in question involved the implementation of a new project management philosophy at Alcan, a multinational company in the aluminum sector, during the construction of an aluminum smelting plant at Alma in Quebec in the early 2000s. This large project involved an investment of over two billion CAD and had the potential to cause significant environmental and socio-economic impacts. Alcan's new project management philosophy and new stakeholder approach directly influenced every stage of the process and were translated into specific and innovative actions that allowed the company to complete the project in the best conditions while obtaining a very high level of social acceptability
Excitonic instability towards a Potts-nematic quantum paramagnet
Magnetic frustration can lead to peculiar magnetic orderings that break a
discrete symmetry of the lattice in addition to the fundamental magnetic
symmetries (i.e., spin rotation invariance and time-reversal symmetry). In this
work, we focus on frustrated quantum magnets and study the nature of the
quantum phase transition between a paramagnet and a magnetically ordered state
with broken threefold () crystal rotation symmetry. We predict the
transition to happen in two stages, giving rise to an intermediate nematic
phase in which rotation symmetry is broken but the system remains magnetically
disordered. The nematic transition is described by the three-state Potts model.
This prediction is based on an analysis of bound states formed from two-magnon
excitations in the paramagnet, which become gapless while single-magnon
excitations remain gapped. By considering three different lattice models, we
demonstrate a generic instability towards two-magnon bound state formation in
the Potts-nematic nematic channel. We present both numerical results and a
general analytical perturbative formula for the bound state binding energy
similar to BCS theory. We further discuss a number of different materials that
realize key features of the model considered, and thus provide promising venues
for possible experimental observation.Comment: 17 pages, 8 figure
Searching for New Physics in Leptonic Decays of Bottomonium
New Physics can show up in various well-known processes already studied in
the Standard Model, in particular by modifying decay rates to some extent. In
this work, I examine leptonic decays of vector resonances of
bottomonium below production, subsequent to a magnetic dipole
radiative structural transition of the vector resonance yielding a pseudoscalar
continuum state, searching for the existence of a light Higgs-like neutral
boson that would imply a slight but experimentally measurable breaking of
lepton universality.Comment: LaTeX, 12 pages, 1 EPS figur
The collaborative process of sustainable innovations under the lens of actor–network theory
The development of sustainable innovation (SI) is complex and risky due to the characteristics and diversity of actors involved in its process. Little is known about the collaborative process underlying this development. The objective of the paper is to explore the collaborative mechanisms and dynamics that influence the process and characteristics of sustainable innovations. The translation approach of the actor–network theory is applied to shed light on the collaborative process of two cases of sustainable innovations within small-and medium-sized enterprises. The sociotechnical graph method is used as a methodology to track the mechanisms and compare the dynamics of their processes. The results reveal that the governance characteristic of sustainable innovations and the moment of mobilization are essential aspects of the collaborative processes. They show that, depending on the intensity and systemic impacts of SI, attraction and retention are important mechanisms in the construction of the governance characteristics of SI. A manager who uses these mechanisms during the mobilization of actors, having resources related to the governance characteristics, succeeds in sustainable innovation development. The paper contributes to the literature on sustainability management by linking the ‘becoming’ of sustainable innovations to their collaborative processes. It also informs managers on how to manage the collaborative process of sustainable innovations by relying on a translation approach. © 2021 by the authors. Licensee MDPI, Basel, Switzerland
Division Algebras and Extended N=2,4,8 SuperKdVs
The first example of an N=8 supersymmetric extension of the KdV equation is
here explicitly constructed. It involves 8 bosonic and 8 fermionic fields. It
corresponds to the unique N=8 solution based on a generalized hamiltonian
dynamics with (generalized) Poisson brackets given by the Non-associative N=8
Superconformal Algebra. The complete list of inequivalent classes of
parametric-dependent N=3 and N=4 superKdVs obtained from the ``Non-associative
N=8 SCA" is also furnished. Furthermore, a fundamental domain characterizing
the class of inequivalent N=4 superKdVs based on the "minimal N=4 SCA" is
given.Comment: 14 pages, LaTe
super KdV equation
We construct supersymmetric KdV equation as a hamiltonian flow on the
super Virasoro algebra. The KdV superfield, the hamiltonian
and the related Poisson structure are concisely formulated in
harmonic superspace. The most general hamiltonian is shown to necessarily
involve breaking parameters which are combined in a traceless rank 2
tensor. First nontrivial conserved charges of super KdV (of
dimensions 2 and 4) are found to exist if and only if the breaking
tensor is a bilinear of some vector with a fixed length proportional to
the inverse of the central charge of algebra. After the reduction
to this restricted version of super KdV goes over to the
integrable case of super KdV and so is expected to be integrable. We show
that it is bi-hamiltonian like its prototype.Comment: 11 pages, preprint ENSLAPP-L-415-9
