We present voters' self-placement and 68 political party locations on the left-right dimension in 17 Latin American countries. Innovative calculations are based on data from Latinobarometer annual surveys from 1995 to 2002. Our preliminary analysis of the results suggests that most Latin American voters are relatively highly ideological and rather consistently located on the left-right dimension, but they have very high levels of political alienation regarding the party system. Both voters' self-placement and the corresponding party locations are presently highly polarized between the center and the right, with a significant weakness of leftist or broadly appealing 'populist' positions.

The simultaneous etherification of isobutene and isoamylenes with ethanol has been studied using macroreticu-lar acid ion-exchange resins as catalyst. Most of the experiments were carried out over Amberlyst-35. In addition,Amberlyst-15 and Purolite CT-275 were also tested. Chemical equilibrium of four chemical reactions was studied:ethyl tert-butyl ether formation, tert-amyl ethyl ether formation from isoamylenes (2-methyl-1-butene and 2-methyl-2-butene) and isomerization reaction between both isoamylenes. Equilibrium data were obtained in a batchwisestirred tank reactor operated at 2.0 MPa and within the temperature range from 323 to 353 K. Experimental molarstandard enthalpy and entropy changes of reaction were determined for each reaction. From these data, the molarenthalpy change of formation of ethyl tert-butyl ether and tert-amyl ethyl ether were estimated. Besides, the chemical equilibrium between both diisobutene dimers, 2,4,4-trimethyl-1-pentene and 2,4,4-trimethyl-2-pentene, wasevaluated. A good agreement between thermodynamic results for the simultaneous etherification carried out in thiswork and those obtained for the isolated ethyl tert-butyl ether and tert-amyl ethyl ether systems was obtained.

L'objecte del present projecte tècnic és la descripció de la climatització d'una nau industrial bioclimàtica, fent ús de sistemes passius i si fos necessari, de sistemes actius. El concepte de bioclimàtic procedeix de bios-vida i clima - orientació. El propòsit d'aquest disseny arquitectònic és que des del punt de vista energètic permeti que la nau mantingui un nivell de confort tant en hivern com en estiu, aplicant una sèrie de criteris de disseny a fi d'utilitzar els elements constructius i funcionals propis de l'edifici per tal d'aconseguir un bon control del seu comportament energètic.

La continua llegada de población inmigrante a los países de la Europa Occidental está produciendo transformaciones en estas sociedades. Evidentemente, la sociedad catalana no es ajena a estos cambios y, año tras año, ve incrementado el número de recién llegados/ as procedentes de orígenes geográficos, culturales y lingüísticos muy diversos. Estas personas, en ocasiones sin un conocimiento previo, se encuentran con las peculiaridades socioculturales y lingüísticas de la sociedad receptora. En el caso de Cataluña, nos interesa destacar la cuestión lingüística, a la cual se han dedicado muchos esfuerzos durante los últimos años en un intento de acercarse a una situación de normalidad en lo referente al conocimiento y uso de la lengua catalana. En el presente artículo se presentan los principales resultados de una investigación centrada en el análisis de los discursos sobre los que anclan las actitudes lingüísticas de los escolares de origen inmigrante en Cataluña. La técnica de investigación social utilizada ha sido la entrevista en profundidad semidirigida, realizando el análisis del contenido de las mismas a partir del «Análisis de contenido temático basado en categorías» (Bardin, 1986). Las conclusiones más relevantes indican que, por encima del Área de Origen o la Condición Lingüística Familiar, la principal variable que permite articular los discursos detectados es la que se puede denominar «Satisfacción y Percepción de Valoración e Integración Escolar y Social», de tal manera que los jóvenes de origen inmigrante que se sienten más valorados e integrados escolar y socialmente desarrollan mejores actitudes hacia la lengua catalana y castellana. Este hecho tiene claras repercusiones respecto las generalizaciones reduccionistas y estereotipadas que vinculan un área de origen con unas determinadas actitudes hacia las lenguas oficiales en Cataluña, así como de cara a la política lingüística y las ideologías lingüísticas de la sociedad en general.

The impact of personality and job characteristics on parental rearing styles was compared in 353 employees. Hypotheses concerning the relationships between personality and job variables were formulated in accordance with findings in past research and the Belsky’s model (1984). Structural equation nested models showed that Aggression-hostility, Sociability and job Demand were predictive of Rejection and Emotional Warmth parenting styles, providing support for some of the hypothesized relationships. The findings suggest a well-balanced association of personality variables with both parenting styles: Aggression-Hostility was positively related to Rejection and negatively to Emotional Warmth, whereas Sociability was positively related to Emotional Warmth and negatively related to Rejection. Personality dimensions explained a higher amount of variance in observed parenting styles. However, a model that considered both, personality and job dimensions as antecedent variables of parenting was the best representation of observed data, as both systems play a role in the prediction of parenting behavior.

A la formación se le asigna capacidad para favorecer la productividad, la competitividad y el acceso a una ocupación. Teniendo en cuenta esta característica, el artículo analiza los cambios y tendencias de la formación inicial, continua y ocupacional en España desde la aprobación del primer Programa Nacíonal de Formación Profesional en 1993, hasta el segundo Programa aprobado en 1998. En este sentido, se observa que los tres subsistemas de formación no están exentos de ciertos puntos débiles que dificultan la plena consecución de los objetivos que tienen asignados y que en ciertos aspectos no han sido corregidos en el nuevo Programa Nacional de Formación Profesional.

The paper discusses the problem of the literary genre of the Crónica sarracina from a peninsular and european points of view. It is considerer through the prism of a new kind of fiction, related to history and an incipient realism, which grows up along the 15th century. Moreover, it reveals new fragments inspired by Pedro de Corral from the catalan version of Seneca’s tragedies and from the Libro de los doce sabios
