Publicado on line en la página de la Fundación Carolina, sección Nombres propios: http://www.fundacioncarolina.es/No voy a entrar en los elementos periodísticos, coyunturales, que ha tenido el
asunto en la vida política del Ecuador. Ni me voy a atrever a hacer un pronóstico
de cara a la decisión prevista para mediados de 2008. Pretendo, simplemente, una
reflexión más general que se puede resumir diciendo que, aunque “otro mundo es
posible”, eso no quiere decir que sea fácil conseguirlo. Ni siquiera por parte de
los que podrían tener poder para lograrlo
Control and eradication strategies for brucella melitensis infection in sheep and goats
Aim: To describe the various strategies for the control and eradication
of B. melitensis infection in sheep and goats.
Methods: The advantages and drawbacks of these strategies are discussed on
the basis of the author’s personal experience and a revision of the relevant literature.
Results: Vaccination programmes in various combinations can be applied either
to decrease the prevalence of infection in the animal population or, when combined
with adequate complementary eradication measures, to achieve a brucellosis-free status.
Conclusion: Controlling the disease should be the primary goal of the veterinary
services involved. However, eradication should be the final objective of any control
programme implemented. The selection of an eradication or control strategy is of
paramount relevance, and a frequent cause of controversy among decision-makers. The
final strategy should be established according to the quality of the veterinary services
organisation, the economic resources available and the extent and prevalence of disease.
Cooperation with farmers is essential to succeed with the application of even the most
elementary control programme. When brucellosis is highly prevalent, mass (wholeflock)
vaccination is the choice to control the disease, independently of the socioeconomic
situation. Once effective control of the disease has been accomplished, its eradication
is feasible. For successful eradication, the adequate quality and organisation of veterinary
services, the strict control of animal movements and the provision of adequate
economic compensation to affected farmers are compulsory. When the disease is fully
eradicated, a surveillance strategy has to be implemented for the early detection of eventual
new outbreaks or disease reintroductio
Feminización de la pobreza y perspectiva de género
El concepto «feminización de la pobreza» se refiere al hecho de que la pobreza afecta, con más frecuencia, a las mujeres. Sin embargo, esta «feminización» no se encuentra reflejada en las mediciones convencionales, e incluso cuando se producen cuantificaciones de la misma no se introduce un elemento fundamental para explicar dicha «feminización», a saber, la posición de la mujer en la estructura social y su vulnerabilidad estructural. Es decir, la perspectiva de género.The concept of the «feminization of poverty» means that poverty largely affects women. Nevertheless, this «feminization» is not reflected in conventional measurements of poverty and, even when it is quantified, one of the fundamental elements for explaining this «feminization» is not taken into account: namely, the position of women in the social structure and their structural vulnerability. That is to say, the gender perspective
PBO Fibres: from saliling design towards architectural performance
p. 3013-3023PBO fibres, also called "high-performance" polymer fibres, are a group of materials known as "rigid rods". Through this work it is pretended to make some considerations about the use of these new generation fibres. Poly (p-phenylene-2.6-benzobisoxazole)(PBO) is rigid-rod isotropic crystal polymer. PBO fibre is a high performance fibre developed by TOYOBO (Japan) PBO fibre is quite flexible and has very soft handling, in spite of its extremely high mechanical properties. Over the past ten years Future Fibres Company has pioneered the use of PBO for yacht rigging and has proven it to provide remarkable performance and longevity. Their method of producing these PBO cables delivers the lightest, smallest cables available on the market today. The PBO cable is formed by combining the incredible properties of PBO (poly(p-phenylene-2,6- benzobisoxazole)) fibre with the simple yet undeniably reliable process of continuous winding.
A PBO cable is dry fibre tightly compacted and does not rely on a resin matrix that, if impacted, can be compromised. The cover of the cable is a vital component and whilst PBO is an excellent material for yacht rigging purposes, due to its extreme strength, low elongation and general robustness it must be protected from sunlight and seawater. Future Fibres has perfected its cover design that comprises a consolidating film, environmental protection layer and a customizable braided cover that can be tailored to suit any specific application. PBO has great potential to be used in construction or rehabilitation applications. At the same time the fibres, following further testing, would open up several design opportunities for high quality architectural projects.Gough, CE.; Pobo Blasco, M.; Ruiz Checa, JR. (2009).

Nuevas tecnologías: nuevos horizontes en la valoración de inversiones
La reconstrucción de la empresa en el nuevo orden económico : VIII Congreso Nacional, IV Congreso Hispano-Francés, Cáceres 7, 8, 9 y 10 de junio de 1994.La emergencia y rápido desarrollo de las nuevas tecnologías de la información
y producción está cambiando las bases de la competencia internacional. La empresa
española, como sus competidoras, ha de hacer frente a este nuevo contexto, siendo
la automatización productiva una de las posibles vías de actuación a su alcance. La
valoración y justificación de las inversiones a llevar a cabo está, por el momento,
regida por los principios convencionales, no aplicables en numerosos casos a los
nuevos activos a valorar, 10 que lleva a retrasar la modernización y renovación de
nuestro entorno industrial. Este trabajo pretende poner de manifiesto la necesidad
de ampliar estos principios, así como de renovar el propio proceso de evaluación y
justificación. Con tal fin, se ha efectuado una revisión detenida de la literatura internacional
reciente y se proponen las bases para el desarrollo de nuevos enfoques.Investigación parcialmente financiada por SEC93-0835-C02-0lInvestigación financiada parcialmente per SEC93-0835-C02-02 y SEC93-0835-C02-0
The use of ICTs to enrich CLIL courses and materials
New technologies are having an increasingly important role in the teaching and learning of languages. They are a useful tool in the CLIL classroom, since they help students to understand content which is taught in a foreign language. This dissertation aims to explore the benefits of ICTs in CLIL and how CLIL teaching and materials could be improved and enriched by using them. An interview with a teacher was carried out. From the answers given, a webpage with several online resources and activities was created. The proposal was implemented and results were drawn. ICTs were shown to help students understand the content, and online games and videos were preferred over the rest of materials. However, only 54 % of the participants used ICTs to revise and study the subject, and 87% assured they would use the webpage section with additional materials. Future studies should consider whether students are really encouraged to use ICTs to complement classroom materials since it has been shown they play a fundamental role in the teaching and learning of languages
