BlueFriends: measuring, analyzing and preventing social exclusion between elementary school students
Resumo:
Social exclusion is a relatively recent term, whose creation is attributed to René Lenoir(Lenoir, 1974). Its concept covers a remarkably wide range of social and economic problems, and can be triggered for various reasons: mentally and physically handicapped, abused children, delinquents, multi-problem households, asocial people, and other social “misfits” (Silver, 1995, pp. 63; Foucault, 1992). With an increasingly multi-cultural population, cultural and social inequalities rapidly ascend, bringing with them the need for educational restructuring. We are living in an evermore diverse world, and children need to be educated to be receptive to the different types of people around them, especially considering social and cultural aspects. It is with these goals that inclusive education has seen an increased trend in today’s academic environment, reminding us that even though children may be taught under the same roof, discriminatory practices might still happen. There are, however, a number of developed tools to assess the various dimensions of social networks. These are mostly based on questionnaires and interviews, which tend to be fastidious and don’t allow for longitudinal, large scale measurement. This thesis introduces BlueFriends, a Bluetooth-based measurement tool for social inclusion/exclusion on elementary school classes. The main goals behind the development of this tool were a) understanding how exclusion manifests in students’ behaviors, and b) motivating pro-social behaviors on children through the use of a persuasive technology. BlueFriends is a distributed application, comprised by an application running on several smartphones, a web-hosted database and a computer providing a visual representation of the data collected on a TV screen, attempting to influence children behaviors. The application makes use of the Bluetooth device present on each phone to continuously sample the RSSI (Received Signal Strength Indication) from other phones, storing the data locally on each phone. All of the stored data is collected, processed and then inserted into the database at the end of each day. At the beginning of each recess, children are reminded of how their behaviors affect others with the help of a visual display, which consists of interactions between dogs. This display illustrates every child’s best friends, as well as which colleagues they don’t interact with as much. Several tips encouraging social interaction and inclusiveness are displayed, inspiring children to change their behaviors towards the colleagues they spend less time with. This thesis documents the process of designing, deploying and analyzing the results of two field studies. On the first study, we assess how the current developed tools are inferior to our measuring tool by deploying a measurement only study, aimed at perceiving how much information can be obtained by the BlueFriends application and attempting to understand how exclusion manifests itself in the school environment. On the second study, we pile on the previous to try and motivate pro-social behaviors on students, with the use of visual cues and recommendations. Ultimately, we confirm that our measurement tool’s results were satisfying towards measuring and changing children’s behaviors, and conclude with our thoughts on possible future work, suggesting a number of possible extensions and improvements.

A atenção à saúde mental (SM) das pessoas idosas é prioritária. Os problemas de SM neste grupo populacional têm aumentado sendo importante investir na prevenção e rastreio dos mesmos. Este estudo teve como objetivos caraterizar do ponto de vista da SM a população idosa da Região Autónoma da Madeira (RAM); determinar as prevalências das situações de SM positiva e negativa e avaliar a influência positiva (protetora) ou negativa (de risco) de certos fatores pessoais e do meio na SM. Foi um estudo transversal no qual participaram 342 pessoas com 65 e mais anos, dos dois géneros, residentes na comunidade. Destes 67,0 % apresentaram SM positiva. A probabilidade da SM ser mais positiva era 2,5 vezes superior quando possuíam 1 a 11 anos de escolaridade (OR = 2,5 IC 95% 1,3 – 4,8); 0,3 vezes inferior nas mulheres (OR = 0,3 IC 95% 0,1 - 0,6), nos idosos com redes sociais muito limitadas (OR = 0,3 IC 95% 0,1 - 0,9) e nos que percecionavam a saúde como razoável ou pior (OR = 0,3 IC 95% 0,1 - 0,9). Era menor 0,5 vezes quando percecionavam a saúde como pior comparativamente aos pares (OR = 0,5 IC 95% 0,3 - 0,9), e 0,3 vezes comparativamente à detida um ano antes (OR = 0,3 IC 95% 0,2 - 0,6). Era 0,1 vez inferior (OR = 0,1 IC 95% 0,1-0,7) nos idosos com limitações físicas para satisfazerem necessidades próprias. Estes fatores devem considerar-se na promoção da SM e na prevenção de perturbações da mesma.
