A mobile health care rule-based system

The relation between patient and physician in most modern Health Care Sys- tems is sparse, limited in time and very in exible. On the other hand, and in contradiction with several recent studies, most physicians do not rely their patient diagnostics evaluations on intertwined psychological and social nature factors. Facing these problems and trying to improve the patient/physician relation we present a mobile health care solution to im- prove the interaction between the physician and his patients. The solution serves not only as a privileged mean of communication between physicians and patients but also as an evolutionary intelligent platform delivering a mobile rule based system.

A mobile systems interface protocol

Recent progresses in the software development world has assisted a change in hardware from heavy mainframes and desktop machines to unimaginable small devices leading to the prophetic "third computing paradigm", Ubiquitous Computing. Still, this novel unnoticeable devices lack in various capabilities, like computing power, storage capacity and human interface. Connectivity associated to this devices is also considered an handicap which comes generally associated expensive and limited protocols like GSM and UMTS. Considering this scenario as background, this paper presents a minimal communication protocol introducing better interfaces for limited devices. Special attention has been paid to the limitations of connectivity, storage capacity and scalability of the developed software applications. Illustrating this new protocol, a case-study is presented addressing car sensors communicating with a central

Neoinstitutionalism and the appropriation of bourdieu's work: a critical assessment

Despite the still present hegemony of the structural-functionalist orthodoxy, the mid 1980's witnesses the insurgence of new philosophical approaches. This body of work had become a vital intellectual and ideological resource for those who wanted to confront the functionalist dominance in organization studies, such as structuration theory, labour process theory and neoinstitutionalist theory. The purpose of this paper is to review the incorporation of Bourdieu's work into neoinstitutionalism. I argue that this appropriation has resulted in a significant loss of theoretical strength. By giving place to the cognitivist metaphors of mental models, "scripts" and "schemas", instead of adopting the notion of habitus, neoinstitutionalism reinforces some of the ever-present dichotomies in social sciences, especially those of agency/structure and individual/society. While neoinstitutionalism was refining the cognitive approach in the 1990's, Bourdieu was moving towards psychoanalysis. Some indications for future research are provided in the concluding notes.

Interaction between information systems and work in the Brazilian banking sector

This article presents the results of a research to understand the conditions of interaction between work and three specific information systems (ISs) used in the Brazilian banking sector. We sought to understand how systems are redesigned in work practices, and how work is modified by the insertion of new systems. Data gathering included 46 semi-structured interviews, together with an analysis of system-related documents. We tried to identify what is behind the practices that modify the ISs and work. The data analysis revealed an operating structure: a combination of different practices ensuring that the interaction between agents and systems will take place. We discovered a structure of reciprocal conversion caused by the increased technical skills of the agent and the humanization of the systems. It is through ongoing adjustment between work and ISs that technology is tailored to the context and people become more prepared to handle with technology.

Continuing and life-long education for Social Work

Pretende defender que a educação contínua e ao longo da vida para o Serviço Social deve levar em conta os caminhos e as perspectivas que ultrapassam a arena da profissão do assistente social, e essa educação deve dialogar com os avanços nas vidas e nos trabalhos profissionais. Os assistentes sociais podem desta maneira moverem-se entre a prática, a gestão, a política profissional e a educação. Desde a experiência pré-qualificadora até à reforma, a avaliação e a supervisão podem ajudar a desenvolver caminhos profissionais e planos de educação relevantes. O exemplo deste processo de educação contínua multiprofissional em St. Christopher’s Hospice London pode ajudar a compreender como as pessoas podem desenvolver-se como pessoas e nos seus projectos profissionais.

Current issues in Social Work Theory

São aqui analisados os discursos sobre as tendências gerais na teoria de Serviço Social. Estes discursos sobre o papel do Serviço Social são tratados no contexto da sociedade, bem como do cliente -assistente sócial -agência. A teoria da prática representa um discurso entre as perspectivas de Serviço Social nos seus aspectos transformacionais, terapêuticos e de ordem social. São também abordadas as suas várias combinações e interacções em todo o tipo de prática e organização de Serviço Social. O discurso sobre a eficácia baseia¬se em estudos comprovados da construção social, potenciação (empowerment), e realismo crítico ainda polémico. A prática reflectiva e crítica constitui os modelos actuais que interligam a teoria e a prática.

The Challenges of Globalisation and Harmonisation for European Social Work

A globalização tem provocado alterações importantes na educação e na prática de Serviço Social. Estas têm a ver com a privatização, dependência do mercado, e a “nova gestão”. Estes factores determinam a resposta dos assistentes sociais aos clientes e a maneira como são tratados como empregados. Os formadores de Serviço Social devem integrar nos seus currículos os elementos associados com a globalização, os conhecimentos e as competências necessárias para a prática em contextos diversificados, e a potenciação (empowerment) dos clientes. É um desafio que está aberto para os planeadores da formação em Serviço Social. A União Europeia tem todo interesse em avançar com uma globalização inclusiva, solidariedade social e justiça social através de Serviço Social relevante. Existem todavia muitos obstáculos que precisam de ser previstos, contornados e ultrapassados.

Social Work in the Portuguese empire Health Services

Muitos historiadores, particularmente estrangeiros, que vêem Portugal “de fora”, têm-se mostrado críticos do mau desempenho do império colonial português.Aintolerância religiosa, uso excessivo de força para conseguir o monopólio de especiarias, são alguns aspectos que mereceram críticas mais duras [Devo admitir que fui eu um destes críticos!] mas quase sempre bem fundamentadas e difíceis de rejeitar. Mas é preciso admitir que a história colonial portuguesa é também feita de elementos positivos e menos violentos. Os portugueses devem ser considerados pioneiros de assistência social através das suas políticas inovadoras que providenciaram cuidados para os doentes e desgraçados, embora estas políticas não abrangessem os sujeitos não-Cristãos do império.

SAR calculation using FDTD simulations

The main intend of this work, is to determinate the Specific Absorption Rate (SAR) on human head tissues exposed to radiation caused by sources of 900 and 1800MHz, since those are the typical frequencies for mobile communications systems nowadays. In order to determinate the SAR, has been used the FDTD (Finite Difference Time Domain), which is a numeric method in time domain, obtained from the Maxwell equations in differential mode. In order to do this, a computational model from the human head in two dimensions made with cells of the smallest possible size was implemented, respecting the limits from computational processing. It was possible to verify the very good efficiency of the FDTD method in the resolution of those types of problems.
