This presentation was made at the Connecticut State Library Service Center, Willimantic, CT, April 14, 2009. It focused on digital capture workflows for both archival and derivative image creation using accepted current standards. Tools used were inexpensive by choice and focused towards the needs of small to mid-sized cultural heritage institutions who wish to begin digital capture in their own facilities.

The Data Envelopment Analysis (DEA) efficiency score obtained for an individual firm is a point estimate without any confidence interval around it. In recent years, researchers have resorted to bootstrapping in order to generate empirical distributions of efficiency scores. This procedure assumes that all firms have the same probability of getting an efficiency score from any specified interval within the [0,1] range. We propose a bootstrap procedure that empirically generates the conditional distribution of efficiency for each individual firm given systematic factors that influence its efficiency. Instead of resampling directly from the pooled DEA scores, we first regress these scores on a set of explanatory variables not included at the DEA stage and bootstrap the residuals from this regression. These pseudo-efficiency scores incorporate the systematic effects of unit-specific factors along with the contribution of the randomly drawn residual. Data from the U.S. airline industry are utilized in an empirical application.

Este artículo muestra cómo la búsqueda identitaria quebequense, se vuelve problemática, cuando compite con una mayoría anglófona. El punto nodal de este dilema ¿cómo se resuelve? ¿La evasión, la errancia, la deambulación, son salidas posibles? La tesis central: los actantes de Volkswagen Blues de Jacques Poulin, sufren un traumatismo monomaníaco: reconstruir una pertenencia por el sesgo de lo fragmentario, del indicio, de los signos, de los recuerdos. Esta obra es la eterna y circular peregrinación de todo ser excluido, exiliado, migrante o minoritario, en búsqueda de una especificidad totalizante y benéfica. Por otro lado, en lo que concierne al aspecto formal, el intertexto, a modo de fábulas encastradas unas en otras, o como fragmentos metadiegéticos, nos conduce a una lectura invertida, no canónica.
