Locus amoenus et locus horribilis : topografía mágica en la literatura caballeresca española

Resumen: El espacio otorga al héroe la posibilidad de situarse en determinado lugar para que se produzca el contacto con la aventura; el espacio resulta, entonces, escenario de las hazañas del caballero y de los logros que producen el perfeccionamiento de sus virtudes. Estos lugares no siempre tienen características edénicas, a veces se manifiestan como auténticos infiernos en los que la aventura se convierte en un verdadero suplicio. Este trabajo tratará de enunciar una posible clasificación de los diferentes lugares mágicos en los que el caballero tiene su encuentro inesperado con lo Otro

Preliminary-results of gaas single-crystal growth under high gravity conditions

GaAs single crystals have been grown under high gravity conditions, up to 9g0, by a recrystallization method with decreasing temperature. The impurity striations in GaAs grown under high gravity become weak and indistinct with smaller striation spacings. The dislocation density of surcharge-grown GaAs increases with increase of centrifugal force. The cathodoluminescence results also show worse perfection in the GaAs grown at high gravity than at normal earth gravity.

The Impact of Firm Level Contracting on Wage Levels and Inequality: Spain 1995-2002

This paper provides microeconomic evidence on the variation over time of the firm-specific wage premium in Spain from 1995 to 2002, and its impact on wage inequality. We make use of two waves of a detailed linked employer-employee data set. In addition, a new data set with financial information on firms is used for 2002 to control as flexibly as possible for differences in the performance of firms (aggregated at industry level). To our knowledge, there is no microeconomic evidence on the dynamics of the firm-specific wage premium for Spain or for any other country with a similar institutional setting. Our results suggest that there is a clear tendency towards centralization in the collective bargaining process in Spain over this seven-year period, that the firm-level contract wage premium undergoes a substantial decrease, particularly for women, and finally that the "centralization" observed in the collective bargaining process has resulted in a slight decrease in wage inequality.

Career Planning in Spain: Do temporary contracts delay marriage and motherhood?

The aim of this paper is to find an empirical connection between the impressive increase in the use of temporary contracts in Spain and the observed increase in age at marriage and maternity. Using a pool of the six available waves of individual information from the European Household Panel for Spain, we find that holding temporary contracts rather than permanent ones delays marriage for males, but not for females. Concerning maternity, the labor market situation of both members of the household affects entry into motherhood. In particular, if woman has a temporary contract rather than a permanent one, motherhoods is delayed independently of the husband's contract. As expected, postponement of maternity is not found for non-working women. These results give strong support to the career planning, motive to delay maternity in Spain, given that an unstable labor market situation of female workers is found to be the main deterrent to entry into motherhood.

Un modelo de programación por metas para la elaboración del contrato-programa de un hospital público

[ES] Proponemos un modelo de programación por metas para la estimación del plan de producción (case-mix) que debe reflejarse en el Contrato–Programa que suscriben anualmente los Hospitales Públicos y la Administración. Las variables de decisión son los volúmenes de actividad de cada servicio médico del hospital y los atributos son los indicadores básicos que se manejan al elaborar el Contrato-Programa: fi nanciación, número de altas, estancia media y peso de complejidad. Para resolver nuestro modelo empleamos la herramienta SOLVER de la hoja de cálculo EXCEL. La utilización de esta herramienta permite simular varios escenarios de una manera ágil, lo que es de gran ayuda para el estudio y discusión de las cantidades a contratar entre el Hospital y la Administración. El artículo finaliza con una breve presentación de los resultados obtenidos al aplicar nuestro modelo a un hospital de tamaño medio (118 camas) del Servicio Vasco de Salud.

Dinámica de las Redes Virtuales de Fabricación Global en la Industria Aeronáutica

[ES] Las redes virtuales de fabricación global (RVFGs) están formadas por empresas independientes las cuales establecen entre sí relaciones de tipo horizontal y vertical, pudiendo incluso ser competidores, donde no es necesario mantener internamente grandes recursos fabriles sino gestionar y compartir eficientemente los recursos de la red.

Proposta de um conjunto de atribuições do gestor de contratos na Câmara dos Deputados

A demanda por bens e serviços de tecnologia da informação no setor público é crescente. Assim sendo, a boa gestão dos contratos de compra de tais bens e serviços é fundamental para a evolução do setor público brasileiro. O presente trabalho teve como objetivo propor um conjunto de atribuições do gestor de contrato na fase de execução contratual, considerando o contexto da Câmara dos Deputados. Para tanto, realizou-se uma análise e classificação das atribuições formais do fiscal de contrato. Tais atribuições estão estabelecidas na Portaria 119/2006 da Câmara dos Deputados, e foram classificadas em atividades de gestão ou fiscalização, justificando-se o motivo da escolha. Constatou-se que algumas atividades a cargo do fiscal de contrato são, na verdade, responsabilidade do gestor de contrato. Adicionalmente, essa classificação definiu um conjunto de responsabilidades do gestor de contrato. Este conjunto foi complementado incluindo-se atividades citadas na legislação e literatura. Concluiu-se também que a ausência de formalização do papel de gestor de contrato na Câmara está em desacordo com a legislação mais recente e literatura.

Two-part tariff licensing mechanisms

Most of the patent licensing agreements that are observed include royalties, in particular per-unit or ad valorem royalties. This paper shows that in a differ entiated duopoly that competes á la Cournot the optimal contract for an internal patentee always includes a positive royalty. Moreover, we show that the patentee would prefer to use ad valorem royalties rather than per-unit royalties when goods are complements or when they are substitutes and the degree of differentiation is suffciently low. The reason is that by including an ad valorem royalty in the licensing contract the patentee can commit strategically to be more (less) aggressive when goods are complements (substitutes) since his licensing revenues become increasing with the price of output of his rival. As a result, licensing may hurt consumers although it always increases social welfare.

Organic Contaminant Analytical Methods of the National Status and Trends Program: 2000-2006

This document describes the analytical methods used to quantify core organic chemicals in tissue and sediment collected as part of NOAA’s National Status and Trends Program (NS&T) for the years 2000-2006. Organic contaminat analytical methods used during the early years of the program are described in NOAA Technical Memoranda NOS ORCA 71 and 130 (Lauenstein and Cantillo, 1993; Lauenstein and Cantillo, 1998) for the years 1984-1992 and 1993-1996, respectively. These reports are available from our website (http://www.ccma.nos.gov) The methods detailed in this document were utilized by the Mussel Watch Project and Bioeffects Project, which are both part of the NS&T program. The Mussel Watch Project has been monitoring contaminants in bivalves and sediments since 1986 and is the longest active national contaminant monitoring program operating in U.S. costal waters. Approximately 280 Mussel Watch sites are sampled on a biennial and decadal timescale for bivalve tissue and sediment respectively. Similarly, the Bioeffects Assessment Project began in 1986 to characterize estuaries and near coastal environs. Using the sediment quality triad approach that measures; (1) levels of contaminants in sediments, (2) incidence and severity of toxicity, and (3) benthic macrofaunal conmmunities, the Bioeffects Project describes the spatial extent of sediment toxicity. Contaminant assessment is a core function of both projects. These methods, while discussed here in the context of sediment and bivalve tissue, were also used with other matricies including: fish fillet, fish liver, nepheloid layer, and suspended particulate matter. The methods described herein are for the core organic contaminants monitored in the NS&T Program and include polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), butyltins, and organochlorines that have been analyzed consistently over the past 15-20 years. Organic contaminants such as dioxins, perfluoro compounds and polybrominated biphenyl ethers (PBDEs) were analyzed periodically in special studies of the NS&T Program and will be described in another document. All of the analytical techniques described in this document were used by B&B Laboratories, Inc, an affiliate of TDI-Brook International, Inc. in College Station, Texas under contract to NOAA. The NS&T Program uses a performance-based system approach to obtain the best possible data quality and comparability, and requires laboratories to demonstrate precision, accuracy, and sensitivity to ensure results-based performance goals and measures.
