Switching Transformations for Decentralized Control of Opinion Patterns in Signed Networks: Application to Dynamic Task Allocation

peer reviewedWe propose a new decentralized design to control opinion patterns on signed networks of agents making decisions about two options and to switch the network from any opinion pattern to a new desired one. Our method relies on switching transformations, which switch the sign of an agent's opinion at a stable equilibrium by flipping the sign of the interactions with its neighbors. The global dynamical behavior of the switched network can be predicted rigorously when the original, and thus the switched, networks are structurally balanced. Structural balance ensures that the network dynamics are monotone, which makes the study of the basin of attraction of the various opinion patterns amenable to monotone systems theory. We illustrate the utility of the approach through scenarios motivated by multi-robot coordination and dynamic task allocation

Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Il Dandy e la moda: Oscar Wilde e Constance Wilde

La storia della moda non ha quasi più confini di campo nè limiti di interpretazione. Il dandy è una delle 'figure' che ritornano più di frequente nel pur rapido susseguirsi delle mode e delle tendenze. Alla sua origine e alla sua evoluzione fra letteratura, arte, storia del costume e moda è dedicato questo saggio, a partire dalla Fin de Siècle ai nostri giorni

Roaming International Ambassadors: The Impact of Faculty and Student Exchange in a Globalized World

The university has the appointed task of searching for, finding and then teaching an adequate culture. Not only does the universitas magistrorum et scholarium, i.e. the whole body of teachers and students, pursue the higher branches of knowledge and research, but it is -- par excellence -- the site for locating the confrontations of the ever-changing plurality of points of view in contemporary multicultural society. Moreover, the university must take a central position between mass media on the one side and society on the other, providing above all the research and analytical tools for the data circulated by the information world. This requires academics to take responsibility in order to pursue, practice, and encourage new, revised conceptions of comparatism, where the role of mediation and “ambassadorship” between different cultures, countries and institutions becomes the necessary step to get to know the culture of the other directly, and to compare different ways of living. That is why the international exchange of faculty and students has become a crucial issue for most academic institutions of ours, more importantly so while promoting more tolerance, and more imagination as well in promoting it. This essay opens an investigation on the functions of “cultural mediation” as played by American Studies, Italian-American Studies, and Italian Cultural Studies -- as well as by Universities, Italian Istituti di Cultura abroad and Embassies. As seen from various angles, under discussion are such roles as interpreters/translators of American culture -- specifically in Italy, Europe, and North America
