Comparação entre os questionários IT-MAIS e MUSS com vídeo-gravação para avaliação de crianças candidatas ao implante coclear

Existe uma grande dificuldade para determinar precocemente crianças que se beneficiariam ou não com o implante coclear, até porque devido à pouca idade são muito sutis as respostas apresentadas. OBJETIVO: Comparar os resultados obtidos através da vídeo-gravação de situações de interação de crianças candidatas ao implante coclear com os resultados obtidos através de protocolos de avaliação. MÉTODO: Fizeram parte da amostra 7 crianças com idade média de 39,7 meses, portadores de perda auditiva neurossensorial profunda. Foram aplicados os questionários IT-MAIS e MUSS aos pais e os resultados foram comparados com a observação da vídeo-gravação destas crianças. RESULTADOS: Foi possível observar que os dados são compatíveis no que se refere às etapas auditivas. No entanto, no que se refere ao questionário MUSS, os dados obtidos na observação lúdica são bastante diferentes. O questionário leva em consideração apenas a uso da linguagem oral e, portanto, a maioria das crianças apresentou um escore muito baixo. CONCLUSÃO: A observação lúdica permitiu traçar um perfil mais amplo do comportamento lingüístico e de aspectos relativos à linguagem apresentando diferenças do questionário.

Find It - An Assistant Home Agent

Cognitive impaired population face with innumerable problems in their daily life. Surprisingly, they are not provided with any help to perform those tasks for which they have difficulties. As a consequence, it is necessary to develop systems that allow those people to live independently and autonomously. Living in a technological era, people could take advantage of the available technology, being provided with some solutions to their needs. This paper presents a platform that assists users with remembering where their possessions are. Mainly, an object recognition process together with an intelligent scheduling applications are integrated in an Ambient Assisted Living (AAL) environment.

IMPLEMENTATION OF GREEN IT IN ORGANIZATIONS: A STRUCTURATIONAL VIEW

ABSTRACTEnvironmental sustainability has become increasingly important to businesses as a response to the rapid depletion of natural resources. Information Technology (IT) in particular represents a meaningful part of the environmental issues that society has been facing. Therefore, Green IT emerges as a way of combining available resources and sustainable and economic policies, thus, generating benefits for both the environment and businesses. The purpose of this paper, hence, is to explain the dynamics of Green IT implementation in organizations in light of the structurationist view of technology. We conducted a case study research based on the cases of three Brazilian companies interested in this movement. Results provide a better understanding of the relationship among technology, individuals, and organization institutional properties, thus enhancing the role played by IT teams in institutionalizing the environmental dimension of sustainability in organizations.

“It came from outer space”: jogos de computador invadem programação e serviços de televisão digital

A convergência da televisão digital com os jogos de computador é cada vez mais uma realidade. Neste artigo serão apresentadas três vertentes desta convergência: – a oferta de jogos pelos operadores de televisão digital e pelos canais de televisão; – a oferta de programação baseada em jogos de computador pelos canais de televisão; – a oferta de jogos com interacção via SMS pelo operadores de televisão digital e pelos canais de televisão, Em conclusão, são apresentadas duas linhas de evolução desta convergência no curto-médio prazo: 1) o lançamento de novos formatos de entretenimento, que conjugam diferentes meios (TV, Telemóvel, PC, PDA, etc) na definição de uma experiência de jogo acessível a qualquer hora e em qualquer lugar, 2) o lançamento de novos aparelhos que aliam as funcionalidades de uma consola de jogos à de uma set-top box avançada de televisão digital.

Política pública inovadora de geração de renda e desenvolvimento local: o caso da Câmara de Animação Econômica da Subprefeitura do Itaim Paulista (CAE-IT), São Paulo, Brasil

O objetivo deste artigo é avaliar, por meio de um estudo de caso único, o funcionamento da Câmara de Animação Econômica da Subprefeitura do Itaim Paulista (CAE-IT), mecanismo pelo qual se buscou fomentar trabalho e geração de renda. A região tem cerca de 380 mil habitantes, um alto índice de violência e um grande número de jovens sem acesso à educação básica e sem oferta de emprego. Diante disso, em 2005, a Subprefeitura articulou-se com uma série de parceiros com quem desenvolveu a ideia da CAE-IT. Inicialmente, buscou compreender a realidade local, através da análise de dados secundários. Em seguida, houve consulta a agentes comunitárias de saúde para compreender quais eram as vocações econômicas da região e em qual público-alvo a política deveria focar esforços. A decisão final foi dar ênfase à promoção de arranjos produtivos locais envolvidos com reciclagem de lixo.

Rise and fall in ischemic heart disease mortality: it may have happened before

The rise in ischemic heart disease(IHD) mortality occurring mostly during the first half of the 20th century is usually associated with economic development and its consequences for people's lifestyles. On the basis of historical evidence, it is postulated that a previous IHD epidemic cycle may have occurred in England and Wales towards the turn of the nineteenth century. The implications of this on causal theories and current etiological research on atherosclerosis are discussed.

Working in IT projects – Options and Limits of Work Design

Flexible forms of work like project work are gaining importance in industry and services. Looking at the research on project work, the vast majority of present literature is on project management, but increasingly, problems concerning the quality of work and the efficiency of project teams become visible. The question now is how project work can be structured in order to simultaneously provide efficient and flexible work and healthy working conditions ensuring the development of human resources for a long time. Selected results of publicly funded research into project work will be presented based on case studies in 7 software development /IT consulting project teams (N=34). A set of different methods was applied: interviews with management/project managers, group interviews on work constraints, a monthly diary about well-being and critical incidences in the course of the project, and a final evaluation questionnaire on project outcomes focusing on economic and health aspects. Findings reveal that different types of projects exist with varying degree of team members’ autonomy and influence on work structuring. An effect of self-regulation on mental strain could not be found. The results emphasize, that contradicting requirements and insufficient organizational resources with respect to the work requirements lead to an increased work intensity or work obstruction. These contradicting requirements are identified as main drivers for generating stress. Finally, employees with high values on stress for more than 2 months have significantly higher exhaustion rates than those with only one month peaks. Structuring project work and taking into account the dynamics of project work, there is a need for an active role of the project team in contract negotiation or the detailed definition of work – this is not only a question of individual autonomy but of negotiation the range of option for work structuring. Therefore, along with the sequential definition of the (software) product, the working conditions need to be re-defined.

Is it possible to remove polymeric nanoparticles from aqueous paints during the activated sludge treatment?

The market for emulsion polymers (latexes) is large and growing at the expense of other manufacturing processes that emit higher amounts of volatile organic solvents. The paint industry is not an exception and solvent-borne paints have been gradually substituted by aqueous paints. In their life-cycle, much of the aqueous paint used for architectural or decorative purposes will eventually be discharged into wastewater treatment facilities, where its polymeric nanoparticles (mainly acrylic and styrene-acrylic) can work as xenobiotics to the microbial communities present in activated sludge. It is well established that these materials are biocompatible at macroscopic scale. But is their behaviour the same at nanoscale? What happens to the polymeric nanoparticles during the activated sludge process? Do nanoparticles agregate and are discharged together with the sludge or remain in emulsion? How do microorganisms interact with these nanoparticles? Are nanoparticles degradated by them? Are they adsorbed? Are these nanoparticles toxic to the microbial community? To study the influence of these xenobiotics in the activated sludge process, an emulsion of cross-linked poly(butyl methacrylate) nanoparticles of ca. 50 nm diameter was produced and used as model compound. Activated sludge from a wastewater treatment plant was tested by the OCDE’s respiration inhibition test using several concentrations of PBMA nanoparticles. Particle aggregation was followed by Dynamic Light Scattering and microorganism surfaces were observed by Atomic Force Microscopy. Using sequential batch reactors (SBRs) and continuous reactors, both inoculated with activated sludge, the consumption of carbon, ammonia, nitrite and nitrate was monitored and compared, in the presence and absence of nanoparticles. No particles were detected in all treated waters by Dynamic Light Scattering. This can either mean that microorganisms can efficiently remove all polymer nanoparticles or that nanoparticles tend to aggregate and be naturally removed by precipitation. Nevertheless respiration inhibition tests demonstrated that microorganisms consume more oxygen in the presence of nanoparticles, which suggests a stress situation. It was also observed a slight decrease in the efficiency of nitrification in the presence of nanoparticles. AFM images showed that while the morphology of some organisms remained the same both in the presence and absence of nanoparticles, others assumed a rough surface with hilly like shapes of ca. 50 nm when exposed to nanoparticles. Nanoparticles are thus likely to be either incorporated or adsorbed at the surface of some organisms, increasing the overall respiration rate and decreasing nitrification efficiency. Thus, despite its biocompatibility at macroscopic scale, PBMA is likely to be no longer innocuous at nanoscale.
