Male and female patterns of labour force participation : a comparison between France and Japan

This article seeks to compare the patterns of articulation - in France and Japan - between the men's activity and women's activity in the society. In particular, we focus on the differences of activity models between French and Japanese women, which can be considered as a good analyser to reveal a specific - and national - form of interdependence between work, family and society. Based on the descriptive macro-statistic method, we aim to show that the national model of women's activity doesn't originate purely neither from the individual rational choice - cost/advantage calculation within the household - nor from the national culture domination. We posit that such a model is a social ‘fabric' which is constructed on the interaction between the strategic interplay of various actors and the national representation of family crystallized in the public social policies.female activity; labour force participation pattern; family; comparison France/Japan; public policy

Goldman systems and bending systems

We show that the moduli space of parabolic bundles on the projective line and the polygon space are isomorphic, both as complex manifolds and symplectic manifolds equipped with structures of completely integrable systems, if the stability parameters are small.Comment: 37 pages, 2 figures; v3: added a referenc

Superconductivity in the Honeycomb-Lattice Pnictide SrPtAs

We report superconductivity in the honeycomb-lattice pnictide SrPtAs with Tc = 2.4 K. To our knowledge, SrPtAs is the first superconducting pnictide with a honeycomb lattice structure. Our finding opens up new playground to develop pnictide superconductors with honeycomb lattices, in addition to square lattices known in iron-based superconductors.Comment: 2 pages, 3 figure

Evaluation of recreation benefit by household production function approach

The travel cost method (TCM) is a revealed preference approach to evaluating the recreation benefit. The traditional application of the TCM is to measure the consumer surplus of recreation sites and activities by calculating the consumer surplus of the site as the area below the demand function and above the implicit price. However, TCM has a setup problem of choke price. The purpose of this paper is to propose the evaluating theory of recreation benefit of environmental quality improvements by household production function approach with revealed preference data. Our approach suggested is operational and allows to decide whether the behavior observed and the household production functions are consistent.household production function, revealed preference, recreation benefit

Ab initio Derivation of Correlated Superatom Model for Potassium Loaded Zeolite A

We derive an effective low-energy Hamiltonian for potassium loaded zeolite A, a unique ferromagnet from non-magnetic elements. We perform ab initio density functional calculations and construct maximally localized Wannier functions for low-energy states made from potassium s electrons. The resulting Wannier orbitals, spreading widely in the alminosilicate cage, are found to be the superatomic s and p orbitals in the confining potential formed by the host cage. We then make a tight-binding model for these superatomic orbitals and introduce interaction parameters such as the Hubbard U. After mean-field calculations for the effective model, we find that ab initio spin density functional results are well reproduced by choosing appropriate sets of the interaction parameters. The interaction parameters turn out to be as large as the band width, $\sim$ 0.5 eV, indicating the importance of electron correlation, and that the present system is an interesting analog of correlated multi-orbital transition metal oxides.Comment: 9 pages, 6 figures, and the top margin was adjuste
