La información se ha convertido en un recurso imprescindible para el proceso de toma de decisiones en las empresas, y elemento fundamental en el proceso de Inteligencia Competitiva. La globalización económica y la libre circulación de mercancías, bien sea dentro de estructuras supranacionales o derivados de la firma de Tratados internacionales, han aumentado el número de competidores presentes en los mercados, pero también las oportunidades para acceder a otros mercados internacionales. Este trabajo describe los recursos de información más importantes que puede necesitar una empresa en su acceso a los mercados internacionales, y que proceden tanto de organismos públicos como privados.

The present paper reports the results of a study aiming to describe the attitudes of teachers in adult continuous education in the Autonomous Community of Andalusia (Spain) towards the use and integration of information and communication technologies (ITC) in the educational centres they work in, while identifying those factors that favour the development of good practice. It is a mixed methods descriptive research, and information collection techniques include a questionnaire and in-depth interviews. A total number of 172 teachers were surveyed, as well as 18 head teachers and coordinators, in adult education. For questionnaire validation the expert judgment technique was used, as they were selected by the «expert competence coefficient» or «K coefficient» procedure. To improve its psychometric properties, construct validity was determined by means of Varimax factor analysis and maximum likelihood extraction (two factors were extracted). Confidence was set by Cronbach's alpha (0.88). The interview guide was also validated by this group of experts. Results point out, on one hand, that teachers hold positive attitudes towards ICT regarding both ICT's role in professional development and their ease of use and access. On the other hand, among the most important factors for ICT-supported good educational practices lies in ICT's capacity to favour personalized work.
