In this article several types of inequalities for weighted sums of the moduli
of Taylor coefficients for Bloch functions are provedComment: 13 page

On the Residuum of Concave Univalent Functions
2000 Mathematics Subject Classification: 30C25, 30C45.Let D denote the open unit disc and f:D→[`C] be meromorphic and injective in D. We further assume that f has a simple pole at the point p О (0,1) and is normalized by f(0) = 0 and f′(0) = 1. In particular, we are concerned with f that map D onto a domain whose complement with respect to [`C] is convex. Because of the shape of f(D) these functions will be called concave univalent functions with pole p and the family of these functions is denoted by Co(p).
We determine for fixed p ∈ (0,1) the set of variability of the residuum of f, f ∈ Co(p)
DUALITY FOR SOME LARGE SPACES OF ANALYTIC FUNCTIONS
We characterize the duals and biduals of the -analogues of the standard Nevanlinna classes , and . We adopt the convention to take to be the classical Smirnov class for , and the Hardy-Orlicz space for . Our results generalize and unify earlier characterizations obtained by Eoff for and , and by Yanigahara for the Smirnov class. Each is a complete metrizable topological vector space (in fact, even an algebra); it fails to be locally bounded and locally convex but admits a separating dual. Its bidual will be identified with a specific nuclear power series space of finite type; this turns out to be the ‘Fréchet envelope' of as well. The generating sequence of this power series space is of the form for some . For example, the s in the interval (\smfr12,1) correspond in a bijective fashion to the Nevanlinna classes , , whereas the s in the interval (0,\smfr12) correspond bijectively to the Hardy-Orlicz spaces , . By the work of Yanagihara, \theta=\smfr12 corresponds to . As in the work by Yanagihara, we derive our results from characterizations of coefficient multipliers from into various smaller classical spaces of analytic functions on .

Évaluation du secteur communautaire du Service social de la Ville de Genève
Le Conseil administratif de la Ville de Genève a mandaté l'IDHEAP en tant qu'expert indépendant pour évaluer le secteur communautaire, une unité administrative rattachée au Service social. En prenant en considération les enjeux socio-sanitaires auxquels la Ville de Genève est confrontée, le concept d'étude proposé par l'Unité de politiques locales et d'évaluation de l'IDHEAP vise à établir un bilan de l'action du secteur communautaire, à déterminer la pertinence de cette action, son efficacité et son efficience, à tracer des perspectives en tenant compte notamment des prestations fournies par d'autres acteurs présents dans les domaines de la cohésion sociale et de la prévention socio-sanitaire, ainsi qu'à proposer des recommandations
