O presente trabalho tem por objetivo estudar o cotidiano dos agregados sociais da Praça da Alfândega localizada no centro da cidade de Porto Alegre no Rio Grande Sul. Foram investigados a partir deste espaço os aspectos relacionais, identitários, as expressões subjetivas e estéticas, as fronteiras de convivências assim como as territorializações empreendidas pelos indivíduos que compõem estes agregados sociais no espaço da Praça da Alfândega. Além disso, esta dissertação tem como intuito discutir as questões pertinentes sobre a função do espaço público, cidadania e dos aspectos sobre as formas de sociabilidade e de insociabilidade nas metrópoles contemporâneas. Pode se dizer que a Praça da Alfândega, nesse mosaico de representações sociais, territórios justapostos e signos compreendem um importante lócus de análise do espaço urbano, motivo pelo fato que ela se apresenta para as formas sociais, denominado de agregados sociais um espaço dicotômico da sobrevivência material e da convivência social. Por esse motivo, o estudo do cotidiano dos agregados sociais presentes no espaço da Praça da Alfândega constituem também uma investigação sobre os fenômenos urbanos contemporâneos e suas múltiplas e emergentes práticas sociais se apresentam nos estilos de vida, das formas simbólicas e nos usos dos espaços nas grandes metrópoles. / This paper aims to study the social aggregations’ every day life from Praça da Alfândega, located in the center of Porto Alegre city in Rio Grande Sul. The aspects of relationship and identity, the subjective and esthetic expressions, the borders of acquaintance as well as the territories settled by people who compounded these social groups in the space of Praça da Alfândega were investigated. Besides, this paper also aims to discuss relevant questions about the function of public space, citizenship and aspects about the forms of sociability and unsociability in modern metropolis. It is possible to affirm that Praça da Alfândega, on this mosaic of social representation adjacent territories and symbols form an important locus of analysis about urban space. For this reason, it becomes a dichotomic space both of material survival and of social acquaintance for the social forms, called social aggregations. Because of this reason, the study of the social aggregations’ every day life settled in Praça da Alfândega constitutes also an investigation about recent urban phenomena and their several and emergent social practices according to ways of life, symbolical forms, and settlement in big cities.

In der Netzwerkgesellschaft des 21. Jahrhunderts gilt die kollaborative Verteilung und Nutzung von Information und Wissen als Schlüsselstrategie für den webbasierten Informations- und Wissenstransfer. Durch die technologischen Möglichkeiten werden technische Zugangsbarrieren weitestgehend überwunden und traditionelle Formen der Wissensvermittlung durch moderne webbasierte Lernumgebungen ergänzt. Der Umgang mit kollaborativen Lehr- und Lernszenarien im dynamischen Informations- und Wissenstransfer bildet die Grundlage für den soziokulturellen Fortschritt innerhalb der Bildungsforschung. Der Schwerpunkt dieser Arbeit lag auf der strukturellen und relationalen Analyse sozialer Organisationsstrukturen innerhalb von Wissensnetzwerken. Ziel war es, Einflussfaktoren offenzulegen, die sich auf das Innovations- und Distributionspotential von Information und Wissen innerhalb von kollaborativen Wissensnetzwerken auswirken. Es wurden dazu Interaktionsprozesse von Teilnehmern innerhalb von Diskussionsforen am Beispiel der Lernplattform OPAL – dem aktuell populärsten Lernmanagementsystem in der Hochschulbildung Sachsens, Deutschland – untersucht. Unter der Annahme, dass soziale Interaktion besonders im Umgang mit kollaborativen Medien den Bildungsablauf und der Aufbau von Wissensnetzwerken die Lehr- und Lernprozesse beeinflusst, wurden in dieser Arbeit die strukturellen Bedingungen des kollaborativen Wissensnetzwerkes in OPAL exploriert und soziale Rollenkonstrukte relational identifiziert, um die Auswirkungen kollaborativer Aktivitäten auf den Informations- und Wissenstransfer in Wissensnetzwerken zu erklären. Es wurden vornehmlich beziehungsorientierte kommunikationstheoretische Modelle zugrunde gelegt und relationale Forschungsmethoden wie SNA (Social Network Analysis) und DNA (Dynamic Network Analysis) angewandt, um eine Basis für die weiterführende Implementierung sozial vernetzter Lehr- und Lernstrategien in der Bildungsforschung zu schaffen. […] / In the network society of the 21st century, a key strategy for web-based exchange of information and knowledge is their collaborative distribution and use. Technical hurdles of access are mostly being overcome with technological advances and traditional forms of passing on knowledge are being complemented by modern, e-learning environments. Within research into education, the foundation for socio-cultural progress is formed by involvement with collaborative teaching and learning scenarios in a dynamic exchange of information and knowledge. The emphasis of this work lay in the analysis of structures and relationships of social organisations within knowledge networks. The aim was to describe the exchange of information and knowledge in collaborative learning systems and to explore its influence on the potential for innovation and distribution of information and knowledge. A study was undertaken of the interaction of participants in discussion forums as exemplified by the learning platform OPAL – currently the most popular learning management system in secondary school education in Saxony, Germany. On the assumption that social interaction, particularly involving collaborative media, the progress of education and the construction of knowledge networks do influence teaching and learning processes, this work explored the structural conditions of OPAL's collaborative knowledge network and identified relationships between social role constructs in order to explain the effect of collaborative activities on the process of diffusion of information and knowledge in knowledge networks. Primarily the study was based on relationship oriented sociological models and communication theory models, and research methods for relationships, including SNA (Social Network Analysis) and DNA (Dynamic Network Analysis) were applied, so as to create a basis for further implementation of social network teaching and learning strategies in educational research.
