Descentralización, integración y policentrismo en Barcelona

En este trabajo se identifican los subcentros de empleo de la Región Metropolitana de Barcelona utilizando diferentes criterios. Una vez catalogados en función de su naturaleza, esto es, subcentros surgidos de la integración y de la descentralización, se contrasta si su impacto sobre la densidad de población depende de su origen. Los resultados obtenidos confirman un mayor impacto de los subcentros integrados en comparación con los descentralizados, amplificada, a su vez, por el hecho de que los primeros están más lejos del CBD y presentan una mayor autocontención en el mercado de trabajo.

Descentralización del empleo: ¿compactación policéntrica o dispersión? El caso de la región metropolitana de Barcelona 1986-1996

La Región Metropolitana de Barcelona (RMB) ha sido caracterizada en repetidas ocasiones como un sistema urbano de tipo policéntrico. Este trabajo pretende corroborar esta afirmación haciendo uso de una metodología que permite identificar los subcentros de empleo y valorar el grado de policentrismo de la RMB en 1986 y 1996. Los resultados obtenidos en los dos años confirman la existencia y extensión del policentrismo.

Auditories energètiques a edificis municipals de tipologia administrativa i d'ensenyament a l'any 2005 : mesures d'estalvi per augmentar la sostenibilitat ambiental i econòmica de les instal·lacions públiques municipals

En aquest document es tracta el tema energètic des de la vessant dels consums en edificis municipals i el tipus de model energètic que aquests tenen implementat. Per a poder portar a terme aquesta tasca s’han realitzat vàries auditories energètiques per conèixer els consums actuals dels edificis i el grau d’eficiència d’aquests, i finalment proposar mesures de millora de la gestió energètica dels edificis estudiats (edificis de la tipologia administrativa i d’ensenyament) i analitzar la possibilitat d’implantació d’energia solar, una font d’energia neta, barata i en concordança amb el medi ambient.

Sôbre o Phlebotomus Brasiliensis Costa Lima, 1932 (Diptera, Psychodidae)

In 1939, Mangabeira obtained, under laboratory conditions, the development of eggs of Phlebotomus brasiliensis Costa Lima, 1932, collected at Lassance (typical locality), Minas Gerais, Brasil. He then studied the female and immature stages of this Phlebotomus. The results of these observations plus some more recent data on the male, geographical distribution and bionomics are presented. Morphologically it is closest to Phlebotomus runoides. However, the male Phlebotomus brasiliensis differs from all other Phlebotomus because of its very long spicules, similar to those of Brumptomyia. The female differs by its longer ducts, and by possessing only four horizontal teeth in the buccal cavity, whereas P. runoides has approximately 12 teeth. The pupae of P. brasiliensis is characterized by its two pre-alar setae, which are very simple and small and by the abdominal setae, which are not planted on a protruding tubercle. The fourth stage larvae main characteristics are very thin antennae, inserted on a protruding tuberculum, and slightly brush-like hind frontal setae. P. brasiliensis is here reported, for the first time, for the State of Bahia (Cachoeira, Pojuca and Salvador). The species has almost always been found in armadillo burrows. In the State of Bahia it is more frequent during the dry season. Under laboratory conditions, the female lays about 53 eggs.

Material Flow Accounting in Chile, Ecuador, Mexico and Peru (1980-2000)

In this paper we compare the resource flows of Chile, Ecuador, Mexico and Peru between 1980 and 2000. In this time span, the domestic extraction of materials increased in the four countries, mainly due to the mining sector in Chile and Peru, biomass and oil in Ecuador and construction minerals in Mexico. Imports and exports increased too, due to the increasing integration in the international markets, prompted by the liberalization policies undertaken by the four countries between the late 1970s and the late 1990s. The four countries had a negative physical trade balance for most of the period analyzed, meaning that their exports exceeded their imports in terms of weight. However, the increase of imports reduced the physical deficit in Chile, Mexico and Peru. Ecuador’s physical deficit was the highest and did not decrease in the period analyzed. Also, a diversification of exports away from bulk commodities could be observed in Chile and Mexico, and to a lesser extent in Peru, whereas in Ecuador the export sector remained mainly based on oil and biomass. More research is needed to explore the environmental effects of this phenomenon. Also, the indirect flows associated to the direct physical flows deserve to be subject to further analysis.

Redescription and resurrection from synonymy, of Aedes (Ochlerotatus) Rhyacophilus Costa Lima, 1933

Aedes (Ochlerotatu) rhyacophilus Costa Lima i resurrected from the synonymy with Aedes (Ochlerotatus) scapularis (Rondani). Lectotype and paralectotypes are designated Larval, pupal and both sexes of adult stages are redescribed and illustrated. Bionomics include a picture of a brreding place. Diagnostic characters for distinguishing rhyacophilus from other species of the Scapularis Group are provided. Some data about known distribution are presented.

Descentralización y estrategias organizativas: las relaciones especiales entre partidos de ámbito estatal (PAE) y partidos de ámbito no estatal (PANE) en España

El objetivo de este artículo es desarrollar un marco analítico que permita examinar y, eventualmente, clasificar qué son y cómo han evolucionado las relaciones especiales entre Partidos de Ámbito Estatal (PAEs) y Partidos de Ámbito No Estatal (PANEs) que acuerdan un marco estable de cooperación no sólo en el ámbito electoral sino también organizativo. Este marco analítico, basado en los conceptos de integración vertical y de autonomía, se aplicará al caso español para analizar las relaciones del Partido Socialista Obrero Español (PSOE) con el Partit dels Socialistes de Catalunya (PSC); el Partido Popular (PP) con Unión del Pueblo Navarro (UPN); e Izquierda Unida (IU) con Iniciativa per Catalunya Verds (ICV).
