Análisis de las políticas sociolaborales en las comunidades autónomas de Asturias, Cantabria, Castilla-La Mancha y Galicia

En el present treball es realitza una exhaustiva anàlis a diferents polítiques sociolaborals de les comunitats autònomes d'Astúries, Cantàbria, Castella-La Manxa i Galícia. Tenint en compte la problemàtica de cada una d'elles, els governs de les comunitats creen diversos programes de suport social amb vista a un desenvolupament i millora de la qualitat de vida de les persones. El programa analitzat per a Astúries és el pla de Salut, Seguretat i Medi Ambient Laboral; a Cantàbria, el pla de Qualificació i Formació Professional; a Castella-la Manxa, l'Institut de la Dona, i finalment Galícia amb el pla gallec d'Inclusió Social.

Nivells de radó en recintes tancats de la zona volcànica de la Garrotxa i la falla d'Amer

La importància radiològica i geofísica del gas radó, un gas radioactiu que neix de la desintegració del radi present a l’escorça terrestre, ha motivat una extensa campanya de mesures d’aquest gas a l’interior de recintes tancats de la zona volcànica de la Garrotxa i de la falla d’Amer, una zona que per les seves característiques geològiques, com ara la presència de falles que poden ser actives, podria afavorir la presència de radó. En aquest treball s’inclou una descripció detallada de la metodologia utilitzada per la mesura d’aquest gas, posant especial èmfasi en el control de qualitat dels sistemes de mesura emprats. Els resultats obtinguts al llarg de més d’un any d’investigacions, on s’han mesurat llocs de treballs i llars, demostren que les concentracions en general són baixes, però que les seves variacions estacionals depenen de la presència de materials volcànics en el subsòl i d’una xarxa de conductes subterranis. Aquest resultat ha motivat uns estudis més detallats dels nivells de radó i altres radionúclids naturals en el sòl al voltant de la falla d’Amer, en les aigües subterrànies i en l’aire dels bufadors de la zona volcànica de la Garrotxa.

The international trade as the sole engine of growth for an economy

Can international trade act as the sole engine of growth for an economy? If yes, what are the mechanisms through which trade operates in transmitting permanent growth? This paper answers these questions with two simple two-country models, in which only one country enjoys sustained growth in autarky. The models differ in the assumptions on technical change, which is either labour- or capital-augmenting. In both cases, the stagnant economy imports growth by trading. In the first model, growth is transmitted because of permanent increases in the trade volume. In the alternative framework, the stagnant economy imports sustained growth because its terms of trade permanently improve.

Biomphalaria obstructa (Morelet, 1849): a study of topotypic specimens (Mollusca: pulmonata: planorbidae)

A description of Biomphalaria obstructa (Morelet, 1849), based on specimens collected at its type locality - isla del carmen, state of Campeche, Mexico - is presented. The Shell is small, 13 mm in diameter, 3.5 mm in width and with 5.75 whorls in the largest specimen, thin, moderately lustrous and translucent, horn-colored. Whorls increasing regularly (neither slowly nor rapidly) in diameter, rounded on the periphery side, bluntly angular on the left. Suture well-marked, deeper on the left. Right side widely concave, with first whorl deeply situated and partly hidden by the next. Left side shallower than right one, largely flattened, with first whorl plaintly visible. Aperture roundly heart-shaped, usually in the same plane as the body whorl but somewhat deflected to the left (less frequently to the right) in some specimens. Peristome sharp, seldom blunt; a distinct callus on the parietal wall. A number of young shells develop one set (seldom more) of apertural lamellae which tend to be resorbed as the shell grows. Absence of renal ridge. Ovotestis with about 70 mostly unbrached diverticula. Seminal vesicle beset with well-developed knoblike to fingerlike diverticula. Vaginal pouch more or less developed. Spermatheca club-shaped when empty, egg-shaped when full, and with intermediate forms between those extremes. Spermathecal body usually somewhat longer than the duct. Prostate with 7 to 20 (mean 12.06 ± 2.51) usually short diverticula which give off plumpish branches spreading out in a fan shape and overlapping to some extent their immediate neighbors. Foremost prostatic diverticulum nearly always partially or completely inserted between the spermathecal body and the uterine wall. Penial sheath consistently narrower and shorter than the prepuce. Muscular coat of the penis consisting of an inner longitudinal and an outer circular layers. Ratios between organ lengths: caudal to cephalic parts of female duct = 0.55 to 1.37 (mean 0.85 +- 0.17); cephalic parte of female duct to penial complex = 1.36 to 2.81 ((mean 1.90 +- 0.33); penial sheath to prepuce = 042 to 0.96 (mean 0.67 +- 0.13). Comparison with Morelet’s type specimens of Planorbis orbiculus and P. retusus points to the identity of those nominal species with B. obstructa.

La función social de los microcréditos

Estudi sobre els microcrèdits centrat no en la seva base econòmica sinó en la funicó que realitzen dins la societat, profunditzant en la situació actual a Espanya tant des d'un punt de vista legal com social, així com en l'anàlisi dels col·lectius més beneficiats per les microfinances: les dones i els immigrants.

A new helminth parasite of fish: Spirocamallanus freitasi sp. n. (Nematoda - Camallanidae)

A new species of nematode is described, Spirocamallanus freitasi sp. n. The worms were collected from fishes (Bergiaria westermanni, Pimelodus maculatus and Pimelodus sp.) living in Três Marias Dam (São Francisco River) in the State of Minas Gerais, Brazil. Spirocamallanus freitasi sp. n. differs from Procamallanus iheringi, P. amarali, P. macaensis, P. (Spirocamallanus) pimelodus, P. (S.) solani and P. (S.) pereirai by having digitated larger spicule and from P. cruzi by having not digitated terminal parts of both spicules. It differs also from P. (S.) intermedius by having not larger spicule divided in two undigitated branches and six to nine sclerotized bands in the buccal capsule; P. rarus has three to four sclerotized bands and tridigitated larger branch of longer speicule, differing from S. feitasi sp. n.

Travassosnema gen. n. with the description of T. travassosi sp. n. (Dracunculoidea, Guyanemidae) parasite of Acestrorhynchus lacustris Reinhardt, 1874 (Characidae) from Três Marias Reservoir, MG, Brazil

A new genus, Travassosnema (Guyanemidae, Dracunculoidea) is proposed to include filariid worms having esophagus divided into muscular and glandular parts, with esophageal appendix near junction with intestine; anus functional; vulva anterior, well developed and functional in mature females. Travassonema travassosi sp. n., a parasite of Acestrorhynchus lacustris Reinhardt, 1874 from Três Marias Reservoir (São Francisco River) in the State of Minas Gerais, Brazil, is described. The generic and the specific names are a tribure to Brazilian parasitologist Lauro Travassos at his birth centenary.

Trabajo y niveles de vida en el Franquismo. Un estado de la cuestión desde una perspectiva de género.

El objetivo del trabajo es plantear preguntas sobre la situación general de las mujeres en el franquismo. Para ver cómo se ha estudiado el trabajo y los niveles de vida de las mujeres en el franquismo es útil distinguir tres grandes temas o niveles de análisis: (a) el Estado franquista, (b) la construcción ideológica y jurídica de "la mujer" y "el varón" como grupos sociales con distintos derechos y funciones, y (c) la división del trabajo entre mujeres y hombres.

The Commons and anti-commons problems in the tourism economy

Countries specialised in tourism tend to face two problems with contradictory effects: the commons and the anti-commons, which lead to tourism over- and under-production, respectively. This paper develops a two-period model to analyse the joint effects of both problems on a small and remote tourism economy. Congestion and the complementariness between foreign transport and local tourism services are key features in this type of markets. As a result, direct selling and the presence of foreign tour-operators emerge as possible market arrangements with different implications in terms of welfare and public intervention. Four main results are obtained. First, in the direct selling situation the optimal policy depends on the relative importance of the problems. Second, the existence of tour-operators always leads to tourism over-production. Third, the presence of a single tour-operator does not solve the congestion problem. Lastly, the switch from several tour-operators to a single one is welfare reducing.
