Tomato response to a high light transmission greenhouse film

Increasing greenhouse light transmission has a positive effect not only in Northern latitudes but in Mediterranean countries as well. A greenhouse, H2, with a tetrafluoroethylene copolymer 60 microns film, (Asahi Glass company, Aflex) characterised by its high light transmission and durability was compared to another greenhouse with a co-extruded film considered as a control, H1. Tomato crop response to the increase in light during winter and summer with high temperature and light was evaluated. Light transmission in H2 remained very high in spite of the observed dust accumulation and the low angle of incidence of the winter solar radiation. Transmissivity was clearly higher for H2 (81 to 83 % throughout the season) than in the control (around 63 %). The rest of the climatic parameters were similar in both greenhouses, either in the winter or in the summer evaluations. In spite of the high solar radiation in H2, the summer temperature could be maintained at the desired levels by using evaporative cooling. Accumulated tomato yield and quality was better in the H2 greenhouse (15 % more for the winter crop and 27% more for the summer crop). Fruit size was bigger in the winter crop. As an overall conclusion, the use of high light transmissive films in Mediterranean areas is very convenient for many vegetable crops. This is valid not only in winter but in summer, provided the greenhouse has good ventilation or evaporative cooling to overcome the increase in sensible heat caused by this increase in light..

El contenido de los puestos de trabajo de los traductores: el caso de los traductores internos en las empresas de traducción de Barcelona

El presente informe es la memoria final de la beca FI que recoge la mayor parte (años 2006-2009) de la investigación realizada en el marco de nuestra tesis doctoral. Se sitúa en el ámbito de la traductología e incorpora elementos conceptuales de la sociología del trabajo y de la organización de empresas. Trata sobre el contenido del trabajo y sus componentes, propios de los puestos de trabajo internos en las empresas de traducción. En la parte conceptual, enfocamos dicho contenido dentro del contexto organizativo de la empresa, dentro del contexto situacional del trabajo real y dentro del contexto del proceso de trabajo que se desarrolla en cada empresa de traducción, cuyo propósito final es producir un servicio de traducción. Además, identificamos la dimensión organizativa e individual del contenido del trabajo. En la parte empírica, analizamos datos procedentes de cuatro empresas de traducción del norte de Francia (fase exploratoria) y de diez empresas situadas en la ciudad de Barcelona (estudio empírico definitivo). Los datos han sido obtenidos mediante entrevistas y observación directa (datos primarios) y mediante los informes de alumnos de prácticas (datos secundarios). Puesto que actualmente (enero de 2010) nos encontramos en la fase del análisis del material empírico recogido, el informe concluye con un primer esbozo de los principales componentes del contenido del trabajo, identificados por nosotros en las empresas de traducción estudiadas. Esperamos ofrecer las conclusiones completas en nuestra tesis doctoral, a punto de finalizar.

The Peace Processes in the Basque Country and Northern Ireland (1994-2006): a Comparative Approach

The peace process in Northern Ireland demonstrates that new sovereignty formulas need to be explored in order to meet the demands of the populations and territories in conflict. The profound transformation of the classic symbolic elements of the nation-state within the context of the European Union has greatly contributed to the prospects for a resolution of this old conflict. Today’s discussions are focused on the search for instruments of shared sovereignty that are adapted to a complex and plural social reality. This new approach for finding a solution to the Irish conflict is particularly relevant to the Basque debate about formulating creative and modern solutions to similar conflicts over identity and sovereignty. The notion of shared sovereignty implemented in Northern Ireland –a formula for complex interdependent relations– is of significant relevance to the broader international community and is likely to become an increasingly potent and transcendent model for conflict resolution and peace building.

Did the cooperative start life as a Joint-Stock company? business law and cooperatives in Spain, 1869–1931

Studies of Spanish cooperatives date their spread from the Law on Agrarian Syndicates of 1906. But the first legislative appearance of cooperatives is an 1869 measure that permitted general incorporation for lending companies. The 1931 general law on cooperatives, which was the first act permitting the formation of cooperatives in any activity, reflects the gradual disappearance of the cooperative’s "business" characteristics. In this paper we trace the Spanish cooperative’s legal roots in business law and its connections to broader questions of the freedom of association, the formation of joint-stock enterprises, and the liability of investors in business and cooperative entities. Our account underscores the similarities of the organizational problems approach by cooperatives and business firms, while at the same time respecting the distinctive purposes cooperatives served.
