In accordance with the mandate it received at the twenty-third session, in this document the secretariat has attempted to delve further into the links among technical progress, international competitiveness and social equity, although it does not, certainly, purport to have exhausted these subjects. Two qualifying remarks are called for here. First, the secretariat is deliberately abstaining from becoming embfoiled in the theoretical aspects of a controversy which has raged for centuries, and particularly since the French revolution, i.e., the debate surrounding the cause-and-effect relationships and possible areas of incompatibility among democratic governance, economic stability, growth and well-being. Rather than concerning itself with doctrine, the secretariat prefers to deal with the realities confronting virtually all the Governments of the region. These realities include the need to resume a sustained (and environmentally sustainable) growth process within the framework of the consolidation of pluralistic, democratic societies -societies that are faced with very real demands to address the many ways in which the majority of the population has been bypassed by development. Secondly, no attempt has been made in this document to provide a list of suitable policies for changing production patterns or for attaining greater social equity. Instead, the focus is on how certain pivotal analytical and policy aspects can be linked within an integrated approach so as to reinforce any existing areas of complementarity between efforts to achieve greater growth and efforts to seek greater social equity. This approach highlights the central tenet of the document: that growth, social equity and democracy can be compatible. What is more, there are significant but as yet largely unexplored areas in which social equity and changing production patterns complement and reinforce one another.

This study investigates the extent to which the digital boom has had repercussions on productive activity, in terms of both manufacturing (ict goods) and services (ict services), in addition to its potential ramifications in the rest of the Mexican economy. Input-output matrices are used and compared to those of Brazil and the United States. Mexico has fallen behind, particularly in the production of ict goods, and the productive chains of this activity have weakened. The ict services sector offers much greater potential than has been exploited thus far, with the advantage that it involves comparatively more value added and has major diversification possibilities. It is considered essential to find more effective industrial policies targeted on the ict goods and services sectors; but the experience of countries such as Brazil, which have applied more proactive approaches with mixed results, suggests that this will be challenging.

Produção de glicose e frutose por invertase de Saccharomyces cerevisiae imobilizada em suporte MANAE-Agarose Invertase de Saccharomyces cerevisiaefoi imobilizada em agarose ativada com diferentes grupos (glioxil, MANAE ou glutaraldeído) e suportes epóxidos comerciais (Eupergit e Sepabeads). Derivados de invertase ativos e estabilizados foram produzidos pela adsorção da enzima em suportes MANAE-agarose, MANAE-agarose tratado com glutaraldeído e glutaraldeído-agarose. Em pH 5,0 estes derivados retiveram total atividade até 24h a 40 ºC e 50 ºC. Quando os ensaios foram a 40 °C e 50 °C com o pH alterado para 7,0, o derivado invertase-MANAE-agarose tratado com glutaraldeído apresentou 80% da atividade inicial. As atividades recuperadas dos derivados foram 73,5%, 44,4% e 36,8%, respectivamente para MANAE, MANAE tratado com glutaraldeído e glutaraldeído. Essas três preparações foram empregadas com sucesso em 3 ciclos de hidrólise da sacarose para produzir glicose e frutose.
