IntroductionMark Weiser's classic article (Weiser, 1991), considered the precursor of Ubiquitous Computing, describes the basic assumptions of this computational paradigm: ubiquity and transparency. These assumptions generate several challenges related to user access to computing environment, anywhere, any time, with any device, non-intrusively, keeping the users' focus on their activities. In this perspective, computational systems must interact in an autonomic way, no matter where the user is, constituting a highly distributed, heterogeneous, dynamic and mobile environment (Costa et al., 2008;Caceres and Friday, 2012 Abstract. The applications in Ubiquitous Computing (UbiComp) environments must be aware of their contexts of interest and adapt to changes in them. Thus, a major research challenge in the area of UbiComp is related to context awareness. Considering the high distribution, heterogeneity, dynamism, and mobility of ubiquitous environments, this paper presents an architectural model for context awareness, called EXEHDA-UC (Execution Environment for Highly Distributed Applications -Ubiquitous Context awareness). The proposal includes elements to support contextual data acquisition, actuation in the environment, and processing of contextual information. We consider that the main contribution of this work is an architecture that supports the managing of the acquisition, storage, and processing of context data, in a distributed way, independently of the application, in an autonomic and rule-based perspective. To assess the functionalities of the EXEHDA-UC, we present a case study, highlighting the prototypes developed, technologies employed, and tests carried out.
Este artigo compõe uma série de estudos teóricos que aproximam alguns filmes da obra Modernidade Líquida, de Zygmunt Bauman, sociólogo polonês; neste texto, será apresentada uma análise do filme Eu, Daniel Blake, tomado como representativo do capítulo Trabalho, da referida obra. O artigo tem, por objetivos, estabelecer uma conexão entre a linguagem cinematográfica e os estudos do sociólogo, além de advogar pelo uso de obras cinematográficas em aulas de diferentes cursos e níveis, visando à experiência estética enquanto possibilidade formadora do ser no mundo. Como metodologia de análise do filme, foram utilizadas as análises textual e de conteúdo, por meio de fotogramas escolhidos. Como resultado da análise, percebe-se que o filme pode ser tomado como uma metáfora do capítulo Trabalho, o que facilita sua compreensão teórica, quando aborda questões como o trabalho informal e as pessoas que se veem alijadas para fora do mundo do trabalho e dos sistemas de proteção do Estado.
