Internet: sala de estudo virtual

Este trabalho relata uma investigação de tipo etnográfico que decorreu na Universidade da Madeira com o objectivo de observar o uso que os estudantes dão aos computadores e, particularmente, à Internet, como auxiliares no estudo e, consequentemente, na aprendizagem. A percepção de que estes meios são comummente usados para além da aprendizagem formal, destacando-se a importância que assume a comunicação online, nas suas várias formas, levou a uma abordagem do papel da comunicação na aprendizagem e na construção e manutenção de comunidades que aprendem em conjunto. O estudo empírico ocorreu numa sala de estudo da UMa, tendo sido valorizada a observação participante na recolha de dados, bem como o recurso a conversas informais e entrevistas não estruturadas. Foi suportado por uma revisão de literatura que incide particularmente sobre a evolução tecnológica e do seu contributo a aprendizagem e como promotora e facilitadora da inovação pedagógica. A aprendizagem, e as diferentes teorias que a explicam, tem aqui um papel relevante, com particular incidência nas teorias que sustentam a aprendizagem pelo uso da tecnologia e dos computadores. A Internet e o seu uso social destacam-se, dando suporte a um aspecto fundamental desta tese que é sua utilização como espaço de aprendizagem. Em todo o trabalho se assume a importância que a Internet tem vindo a ter nos processos de estudo e aprendizagem, tornando-se mesmo insubstituível no quotidiano académico da grande maioria dos estudantes.

Práticas discursivas em blogs políticos: uma observação sobre a participação política e as trasnformações que acompanham o espaço público

This work discuss about the transformation of public space, based on the recent challenges imposed by communication practices that are renewed and recopying of the sociocultural contexts of everyday life. The study presents theoretical and empirical reports of regional political blogs. In this issue, it looks for understand the political participation in the Internet space, examining the reconfigurations that accompany social relations and new forms of interaction that are merged in the media scene. The ambience of the study limits comments of readers in two political blogs in Rio Grande do Norte, Território Livre, and Thaisa Galvão. The observation concerns about the democratic participation of citizens in matters of collective interest, during the 2010 election. The analysis update the debate on democratic discussion and conversation everyday, trying to grasp changes in social practices in virtual platforms. From this perspective, the work restores some conceptual notions that involve the public places, identifying the changes that appear in the virtual and traditional spheres, with the emergence of new places of conversations, from the Internet usage. Are also compared to similarities and differences between the two elements of the analysis. It is possible, therefore, the communication process of the two discursive spaces with ideas from the public sphere, trying to analyze the duality between public, private, and political participation in these virtual places

O serviço social na previdência social: a afirmação do seu espaço na materialização dos direitos

The work of the professional of social worker in social security policy, it is seen wrapped in an adverse situation to consolidate the ethical-political project work, marked by the materialization of the neoliberal policy essentially promotes the reduction of social rights historically achieved by the class struggle worker. In this sense, with the aim of analyzing the statement of work of the Social Worker in Social Security, their struggles and challenges to the realization of rights, against the current situation is that it renders the theoretical basis of the discussions to be fought. Thus, we performed procedures such as methodological research literature and documents in detail of our analytical categories in order to base the discussion on social security policy. The survey area covered was the Executive Management of Social Security Mossoró and Natal, representing a total of 07 (seven) surveyed social workers who work in the Department of Social Work. Thus, the research allowed us a comparison with the work of Social Workers and this allowed us to reach some conclusions: first, the fact that Social Security does not guarantee in its entirety, the conditions necessary for the work of Social Worker, taking into account the lack of human and material resources for its realization, and the virtual absence of professional secrecy, and second, that the social workers surveyed say the ethical-political project of Social Work, in exercise professional from engaging in projects and social movements related to the protection of social rights and working class, thirdly, that the statement of professional design, contributes to the formation of a new professional activities, based on an analysis of whole and an action more interventionist, critical and purposeful, able to relate to the interests of users who seek their services, the consolidation and socialization of social rights. Thus, the direction of the work of professional of social worker to support the theoretical and methodological maturity in recent years acquired the expertise and ethical-political daily, consolidated its space in claiming social security institution, the rights so hard fought in an environment grounded in the disintegration social struggles

Sistemas computacionais espaço-temporais para toma de decisão em questões ambientais relacionadas à indústria de petróleo e gás

The area between São Bento do Norte and Macau cities, located in the northern coast of the Rio Grande do Norte State is submitted to intense and constant processes of littoral and aeolian transport, causing erosion, alterations in the sediments balance and modifications in the shoreline. Beyond these natural factors, the human interference is huge in the surroundings, composed by sensitive places, due to the existence of the Guamaré Petroliferous Pole, RN, the greater terrestrial oil producing in Brazil, besides the activities of the salt companies and shrimp farms. This socioeconomic-environmental context justifies the elaboration of strategies of environmental monitoring of that coastal area. In the environmental monitoring of coastal strips, submitted to human impacts, the use of multi-sources and multitemporal data integrated through a Spatio- Temporal Database that allows the multiuser friendly access. The objective was to use the potential of the computational systems as important tools the managers of environmental monitoring. The stored data in the form of a virtual library aid in making decisions from the related results and presented in different formats. This procedure enlarges the use of the data in the preventive attendance, in the planning of future actions and in the definition of new lines of researches on the area, in a multiscale approach. Another activity of this Thesis consisted on the development of a computational system to automate the process to elaborate Oil-Spill Environmental Sensitivity Maps, based on the temporal variations that some coastal ecosystems present in the sensibility to the oil. The maps generated in this way, based on the methodology proposed by the Ministério do Meio Ambiente, supply more updated information about the behavior of the ecosystem, as a support to the operations in case of oil spill. Some parameters, such as the hydrodynamic data, the declivity of the beach face, types of resources in risk (environmental, economical, human or cultural) and use and occupation of the area are some of the essential basic information in the elaboration of the sensitivity maps, which suffer temporal alterations.In this way, the two computational systems developed are considered support systems to the decision, because they provide operational subsidies to the environmental monitoring of the coastal areas, considering the transformations in the behavior of coastal elements resulting from temporal changes related the human and/or natural interference of the environment

Letramento e Oralidade: Notas sobre Pontuação em um Bate-papo Virtual Infantil

Based on a heterogeneous concept of writing, this paper aims at analyzing ‘breaks’ in utterances of a virtual chat for writers between 8 and 12 years of age. The hypothesis is that the segmentation of an utterance in different lines in a short period of time characterizes the writing on the internet as nonconventional and relates it to the prosody and rhythm of the language not restricted to the phonic or graphic dimension of the verbal language.
