Organization and dynamics of Conselho Municipal de Seguranca Alimentar e Nutricional de Sao Paulo: implications of their participation on the creation of a municipal food and nutrition security policy

Objective This study analyzed the internal functioning, organization and political participation of the local food and nutrition security council and possible implications of their participation on the creation of a municipal food and nutrition security policy in the city of Sao Paulo. Methods This qualitative study was done in three stages: document analysis; observation of meetings and semi-structured interviews with board members considered key informants. The axis of analysis was the political participation of the council, considering its internal aspects, like board members, operating dynamics of political participation of its members and the relationship between these topics and the council's actions for the definition and creation of a food and nutrition security policy. Results The intellectual profile of the board members does not represent the majority of the population, thereby facilitating the omission of actual issues in council discussions. Its strict internal dynamics and the asymmetry of its members generally prevent the active participation of board members and, specifically, discussions about a food and nutrition security policy. The so-called "militant members" have a differentiated, more aggressive participation, with greater mastery of the subject and its topics. Conclusion The board member profiles, internal organization of the council, complexity of the subject and its low insertion in the society distance the council from social needs and lead them to act incipiently with regard to the municipal policies of food and nutrition security.

Nuevas Técnicas de Transmisión de Muy Alta Velocidad para Redes de Computadores: Una aproximación mediante ondículas.

Indoor multpropagation channel is modeled by the Kaiser electromagnetic wavelet. A method for channel characterization is proposed by modeling all the reflections of indoor propagation in a kernel function instead of its impulse response. This led us to consider a fractal modulation scheme in which Kaiser wavelets substitute the traditional sinusoidal carrier.

Relaciones entre computadores y sociedad (Socioinformática)

El título de este capítulo se corresponde con el nombre del TC 9 (Comité Técnico de IFIP), en el que fui representante español durante unos años, hasta mi dimisión por motivos éticos. Curiosa paradoja, si se tiene en cuenta que este Comité se ocupa, entre otras variadas cosas, de los problemas éticos de la Informática.

Convivencialidad, complejidad, computadores e informática

Dice el sociólogo Daniel Bell que la sociedad postindustrial girará en torno a la información y al saber. Todo esto parece una abstracción,un diseño de ideas construido sobre un armazón de tendencias más o menos consolidadas. Pero ha hecho fortuna, y hoy esa metáfora está integrada formalmente en el cotidiano discurso político, social y económico, incluso en situaciones de dudosa aplicabilidad.
