22 p, 220.2 KB Improving small area estimation by combining surveys : new perspectives in regional statistics / Costa, Alex (Institut d'Estadística de Catalunya) ; Satorra, Albert (Universitat Pompeu Fabra) ; Ventura, Eva (Universitat Pompeu Fabra)
A national survey designed for estimating a specific population quantity is sometimes used for estimation of this quantity also for a small area, such as a province. Budget constraints do not allow a greater sample size for the small area, and so other means of improving estimation have to be devised. [...]

18 p, 256.1 KB Improving both domain and total area estimation by composition / Costa, Alex (Institut d'Estadística de Catalunya) ; Satorra, Albert (Universitat Pompeu Fabra) ; Ventura, Eva (Universitat Pompeu Fabra)
In this article we propose small area estimators for both the small and large area parameters. When the objective is to estimate parameters at both levels, optimality is achieved by a sample design that combines fixed and proportional allocation. [...]

23 p, 294.2 KB An empirical evaluation of five small area estimators / Costa, Alex (Institut d'Estadística de Catalunya (Idescat)) ; Satorra, Albert (Universitat Pompeu Fabra) ; Ventura, Eva (Universitat Pompeu Fabra)
This paper compares five small area estimators. We use Monte Carlo simulation in the context of both artificial and real populations. In addition to the direct and indirect estimators, we consider the optimal composite estimator with population weights, and two composite estimators with estimated weights: one that assumes homogeneity of within area variance and squared bias and one that uses area-specific estimates of variance and squared bias. [...]

8 p, 217.0 KB Tradición y traducción en el modernismo hispanoamericano / Costa, Analía (Universidad Nacional de Rosario. Facultad de Humanidades y Artes)
Se mostrará cómo la traducción se convierte en un mecanismo constante que atraviesa las preocupaciones centrales de los escritores del modernismo literario hispanoamericano, convirtiéndose en un recurso fundamental para llevar adelante el proyecto de modernización de la lengua y la literatura de finales del siglo XIX y comienzos del XX. [...]
We will show how translation becomes a permanent mechanism that goes through the main concerns of the writers of Spanish American modernist writers, thus being a key resource for carrying out the project to modernize the language and literature of the late 19th and early 20th centuries. [...]

Let f be a germ of plane curve, we define the 8-degree of sufficiency offto be the smallest integer r such that for any germ g such that j(r)f = j(r)g then there is a set of disjoint annuli in S3 whose boundaries consist of a component of the link of f and a component of the link of g. [...]

The existence of some popular beliefs has been referred to by several studies. A few of these popular beliefs, which seem to be also widespread in Portugal, are related to biological contents. Therefore, it can be expected that many students hold some of these beliefs when they come to the biology classes. [...]
