How to assess the impact of courses aimed at problem-people : a discussion of a case-study In the context of high unemployment, a considerable course market has developped but their impact on finding a job remains quite uncertain. This paper provides an evaluation of a course aimed at problem job seekers, carried out in Bourgogne (middle-east region). Course attendance is most likely to be linked to job hunting and the setting up of more elaborate career plans. It looks as if other psychological changes are negligeable. Moreover, this assessment raises the question of the possible evil effects of such development on a more general level.
Las mujeres españolas en la Resistencia francesa
1996
La aproximación metodológica que constituye el objeto de este estudio comprende dos aspectos. En primer lugar, un estado de la cuestión respecto a bibliografía y fuentes, tanto más necesario cuanto el tema de la participación de los españoles en la «resistencia» francesa, no fue tratado en el Coloquio de Salamanca. Y en segundo término, un «estado de la cuestión» referido al conocimiento que hioy tenemos sobre la participación de las mujeres. En él se trata de sistematizar en algunos epígrafes, la información que sobre la misma proporcionan la bibliografía y fuentes de archivo y hemerográficas, además de testimonios orales en su mayoría ya publicados. Después de varios esfuerzos puedo utili…
Improved tau polarisation measurement
1996
Using 22 pb−1 of data collected at LEP in 1992 on the peak of the Z resonance, the ALEPH collaboration has measured the polarisation of the tau leptons decaying into $$ev\bar v, \mu v\bar v$$ ,πν, ρν and a1 ν from their individual decay product distributions. The measurement of the tau polarisation as a function of the production polar angle yields the two parametersN τ andN e, where, in terms of the axial and vector couplingsg Al andg Vl,N l=2g Vl gAl/(g Vl 2 +g 2 ). This analysis follows to a large extent the methods devised for the 1990 and 1991 data but with improvements which bring a better understanding of the systematic uncertainties. Combining the 1992 measurements with our previous…

Atomic and Electronic Structure of the Corundum (0001) Surface
1996
AbstractThe electronic structure and geometry of the Al terminated corundum (0001) surface were studied using a slab model within the ab-initio Hartree-Fock technique. The distance between the top Al plane and the next O basal plane is found to be considerably reduced on relaxation (by 0.57 Å, i.e. by 68% of the corresponding interlayer distance in the bulk). An interpretation of experimental photoelectron spectra (UPS Hel) and metastable impact electron spectra (MIES) is given. Calculated projected densities of states exhibit a strong dependence on the relaxation of surface atoms.
Investigation of the porosity of silica and alumina with chemically bonded polystyrene
1996
The effect of modification of porous silica and alumina with a copolymer of styrene and vinylsilane on the porosity of oxides have been investigated by means of low temperature nitrogen sorption. Only small changes of the specific surface area and of the specific pore volume were observed on modification of oxides with non-cross-linked copolymer. The specific surface area significantly increased after the cross-linking of the deposited polymeric layer while the specific pore volume remains almost unaffected. A broad hysteresis loop appears in the nitrogen sorption isotherm for the alumina modified with the cross-linked polymer. The porosity of oxides modified by chemisorption method differe…
Updated precision measurement of the average lifetime of B hadrons
1996
The measurement of the average lifetime of B hadrons using inclusively reconstructed secondary vertices has been updated using both an improved processing of previous data and additional statistics from new data. This has reduced the statistical and systematic uncertainties and gives \tau_{\mathrm{B}} = 1.582 \pm 0.011\ \mathrm{(stat.)} \pm 0.027\ \mathrm{(syst.)}\ \mathrm{ps.} Combining this result with the previous result based on charged particle impact parameter distributions yields \tau_{\mathrm{B}} = 1.575 \pm 0.010\ \mathrm{(stat.)} \pm 0.026\ \mathrm{(syst.)}\ \mathrm{ps.}

Le masculin et le féminin dans les modèles éducatifs parentaux
1996
International audience; Cet article est réalisé à partir de l'exploitation de l'enquête "Efforts d'éducation des familles" (Insee/Ined), qui a concerné en 1992 5300 ménages ayant au moins un enfant scolarisé de 2 à 25 ans. D'un milieu à l'autre, les parents nourrissent des ambitions différentes pour les filles et les garçons. Les auteurs présentent quelques éléments sur les aspirations éducatives des parents, avant de s'arrêter sur les modèles éducatifs et les valeurs déclarées qui peuvent être considérés comme sous-jacentes aux premières.
Christian Konrad Sprengel’s Theory of the Flower: The Cradle of Floral Ecology
1996
As the plant taxonomist Karl Suessenguth once wrote, there are two kinds of discoveries: Detecting a thing nobody has seen before, or thinking what no one has thought before about something that everybody sees. A discovery of the second kind, and one of great moments in our science, was Sprengel’s theory of the flower. This theory clearly expressed for the first time the notion that flowers are designed for the transmission of pollen by foreign vectors, that is, animals or wind, and they can be understood only from this perspective.
Assembling Magnetic Blocks: A Strategy to Control the Nuclearity and Magnetic Properties of Polynuclear Complexes
1996
Synthetic strategies dealing with the polymerization of either di-μ-hydroxocopper(II) complexes or 2,2′-bipyrimidine (bpym)-containing first row transition metal ions allow the preparation of polynuclear compounds whose structures and magnetic properties are presented here. The influence of structural and chemical parameters on the magnitude of the singlet-triplet energy gap (J) in di-μ-hydroxocopper(II) complexes [LCu(OH)2CuL]2+ with L = 2,2′-bipyridine (bpy) and bpym is analyzed and discussed. Special attention is devoted to nature of the counterion which allows the preparation of hydroxo-bridge copper(II) cubane and double cubane type complexes where all the intramolecular magnetic inter…
Synthesis and Characterization of Adducts Derived from the syn-Diastereomer of Benzo[a]pyrene 7,8-Dihydrodiol 9,10-Epoxide and the 5‘-d(CCTATAGATATCC…
1996
5'-d(CCTATAGATATCC) was reacted with each syn-enantiomer of trans-7,8-dihydroxy 9,10-epoxy 7,8,9,10-tetrahydrobenzo[a]pyrene (syn-BPDE). The (-)-enantiomer yielded one dominating adduct, whereas the (+)-enantiomer resulted in two major adducts. As indicated by optical spectroscopic methods, the major adduct derived from both (-)- and (+)-syn-BPDE involves cis addition of the C-10 position of the diol epoxide to the exocyclic amino group of deoxyguanosine [(-)-syn-BPDEc-N2-dG and (+)-syn-BPDEc-N2-dG, respectively], whereas the minor (+)-syn-BPDE adduct is identical to a trans adduct [(+)-syn-BPDEt-N2-dG]. The cis adducts as well as the (+)-syn-BPDEt-N2-dG adduct are chemically stable for sev…

Tasas de erosión en una solana de la serra grossa: La costera
1996
Mediante el uso de la lluvia simulada (55 mm durante una hora) se estudia el comportamiento hidrológico y erosivo de los suelos de una ladera de exposición sur sobre calizas en la Serra Grossa, La Costera. Tanto las tasas de erosión (10 g m h) como los coeficientes de escorrentía (12%) son muy reducidos a la escala en que se ha realizado la medición (0,25 m). La posición en la ladera, la humedad del suelo y la concentración de sedimentos -al contrario que la vegetación y la tasa de escorrentía- no determinan las tasas de erosión cuando las mediciones se realizan bajo condiciones de sequedad extrema durante el verano. Las bajas tasas de escorrentía durante el verano ante lluvias de elevada i…

Electrocatalytic properties of ferrooctacarboxyphthalocyanine(II). Electrocatalytic oxygen reduction on the mercury electrode in aqueous solutions
1996
Electrocatalytic reduction of oxygen in aqueous solutions in the presence of ferrooctacarboxyphthalocyanine was investigated. The decay of catalytic properties is attributed to the phthalocyanine aggregation. The mechanism for the four-electron electrocatalytic O2-reduction in neutral and basic media involving FePc(COOH)8 is proposed. It has been found that monomers of phthalocyanine, which are able to form μ-peroxo structures, are the catalytically active forms. The adsorption of various phthalocyanine forms on the mercury electrode plays a very important role in the overall catalytic reaction.

Surface Ordering and Surface Segregation in Binary Alloys
1996
Many technologically relevant properties of metallic alloys are determined by the structure of their surfaces, especially in the field of catalysis and corrosion. One important aspect of a surface or grain boundaries is, that the stoichiometry of the alloy close to the surface normally differs from the bulk stoichiometry. Due to different interaction energies and different atom sizes of the components, one of them will get enriched at the surface, a phenomenon called surface segregation[1].

Les Expressions Figées des Verbes Ser et Estar Suivies de Prép X
1996
The present work is based on the methodological setting of the LADL studies. In order to establish the body subject to analysis, we selected only the fixed phrases N0 ser/estar Prep X. In this way, we have collected 1138 expressions involving estar Prep X, and 534 with ser Prep X. In order to classify these expressions, we have grouped them according to the number and form of their complements. As to the part pertaining to semantics, the alphabetical indices have allowed us to establish that, concerning ser and estar, all the formal schemes exists for both Spanish and french, at least under the form of fixed expressions. As to the part concerning translation, we have attempted to mesure the…
NIMBUS — Interactive Method for Nondifferentiable Multiobjective Optimization Problems
1996
An interactive method, NIMBUS, for nondifferentiable multiobjective optimization problems is introduced. We assume that every objective function is to be minimized The idea of NIMBUS is that the decision maker can easily indicate what kind of improvements are desired and what kind of impairments are tolerable at the point considered.

Cuaternario submarino frente a la Serra Gelada (Alicante) y sus implicaciones eustático-paleogeográficas
1996
Los estudios sobre el Cuaternario (Pleistoceno-Holoceno) de la plataforma continental frente a la Serra Gelada, basados en perfiles sísmicos de alta resolución (Geopulse 175 julios), permiten establecer que la secuencia sísmica está constituida por 7 unidades deposicionales principales y su configuración morfosedimentaria se relaciona con los procesos que han interve nido en la edificación del litoral y de las provincias interna y media de la plataforma continental. Los factores que han condicionado la evolución y construcción de la plataforma durante en el Cuaternario han sido principalmente las variaciones eustáticas, la neotectónica, los aportes continentales y los mecanismos de distribu…
