In Trusts We Trust: Pension Funds Between Social Protection and Financial Speculation.
les rĂ©formes europĂ©ennes des retraites ont pris pour rĂ©fĂ©rence le systĂšme amĂ©ricain. cet article propose de comprendre les origines d'une telle croyance persistante dans les vertus des fonds de pension. l'analyse met en Ă©vidence le rĂŽle jouĂ© par leur structure juridique, le trust, dans la lĂ©gitimation de la "pension industry".Recent reforms of European pension schemes have largely taken the American system as a reference.The remarks which follow are aimed at understanding the origins of such a persistent belief in the virtues of the pension funds. The analysis brings out the role played by their legal structure, the trust, in the legitimisation of the âpension industryFonds de pension; Trust;

Faith-based voluntary action: a case study of a French charity
Following legal changes in the 1980s, the Voluntary and Community sector/Ă©conomie sociale in France has become culturally diverse as faith-based organisations serving minority ethnic communities have developed, including charities inspired by religious and cultural principles of charitable giving. In this article, we use a case study of a social welfare charity established in a Parisian suburb with a culturally diverse population. Worldwide social welfare work is a priority; the charity responds to disasters, but it prioritises long-term development actions, encouraging the direct involvement of local communities. In recent years, its work has also embraced distressed communities within France
Localized structures in coupled Ginzburg-Landau equations
Coupled Complex Ginzburg-Landau equations describe generic features of the
dynamics of coupled fields when they are close to a Hopf bifurcation leading to
nonlinear oscillations. We study numerically this set of equations and find,
within a particular range of parameters, the presence of uniformly propagating
localized objects behaving as coherent structures. Some of these localized
objects are interpreted in terms of exact analytical solutions.Comment: 7 pages, 3 postscript figures, uses the elsart style files. Related

Numerical Study of a Lyapunov Functional for the Complex Ginzburg-Landau Equation
We numerically study in the one-dimensional case the validity of the
functional calculated by Graham and coworkers as a Lyapunov potential for the
Complex Ginzburg-Landau equation. In non-chaotic regions of parameter space the
functional decreases monotonically in time towards the plane wave attractors,
as expected for a Lyapunov functional, provided that no phase singularities are
encountered. In the phase turbulence region the potential relaxes towards a
value characteristic of the phase turbulent attractor, and the dynamics there
approximately preserves a constant value. There are however very small but
systematic deviations from the theoretical predictions, that increase when
going deeper in the phase turbulence region. In more disordered chaotic regimes
characterized by the presence of phase singularities the functional is
ill-defined and then not a correct Lyapunov potential.Comment: 20 pages,LaTeX, Postcript version with figures included available at
