Cherbourg revisited: hearing health changes in an Aboriginal community, 1972 to 2000

The aim of this study was to investigate current audiological outcomes of Cherbourg schoolchildren and compare these outcomes to those obtained in a 1972 study of hearing health in the same community. Seventy-eight primary school children of Cherbourg State School participated in the study. Their peripheral hearing and middle ear function were tested using pure-tone air conduction audiometry and tympanometry respectively. A significant improvement in the hearing status of this population was noted compared to that reported in 1972. The improvements in the hearing status of Indigenous schoolchildren at Cherbourg can be attributed to a number of factors, including increased awareness of both ear health and general health, as well as the introduction of hearing health care services, over the past three decades.

As estatais e as PPPs: o project finance como estrat??gia de garantia de investimentos em infra-estrutura

Este trabalho discute o papel das estatais nas PPPs, de modo a garantir investimentos em infraestrutura pelo financiamento via project finance. Partindo de um contexto de privatiza????es desse setor, que, no Brasil, efetivou-se na d??cada de 1990, buscou-se mostrar como surgiu espa??o para o estabelecimento de PPPs, advindas de novas institui????es resultantes do processo de reforma do Estado. O project finance ?? colocado como uma forma de garantir o financiamento desses investimentos. Sua estrutura financeira, baseada na cria????o de uma pessoa jur??dica para a gest??o do empreendimento, busca dirimir os riscos pela eleva????o do n??mero de participantes e pela securitiza????o de receitas futuras, tornando-as l??quidas em curto prazo. A discuss??o sobre o papel do project finance revela que essa ?? uma estrat??gia vi??vel para a garantia de investimentos por parte das estatais, em parceria com o governo e com outras empresas, que levem ao desenvolvimento socioecon??mico sustent??vel do Pa??s.

Educação escolar Tupinikim e Guarani : experiências de interculturalidade em aldeias de Aracruz, no Estado do Espírito Santo

A pesquisa analisa as relações entre interculturalidade, práxis e educação escolar indígena Tupinikim e Guarani do município de Aracruz, Espírito Santo, Brasil. Investiga a práxis da educação intercultural no espaço da educação escolar indígena como meio de revitalização das culturas Tupinikim e Guarani. Objetiva problematizar a formação inicial e continuada dos professores indígenas; discutir a práxis da interculturalidade no contexto da educação escolar indígena; e, identificar outros espaços educativos da cultura e educação indígena. Analisa aspectos teóricos e práticos sobre cultura (WILLIAMS, 2008; BRANDÃO, 1989; FORQUIN, 1993; CANDAU, 2011; GEERTZ, 1989), interculturalidade (D‘AMBROSIO,1996; FLEURI, 2002; 2003; SCANDIUZZI, 2009;), identidade e alteridade (MELIÁ, 2000; FREIRE, 1981; 1987; LITAIFF, 2004) e práxis (FREIRE, 1989; VÁSQUEZ, 2011; SEMERARO, 2006) e educação (escolar) indígena de acordo com a legislação vigente. Realiza pesquisa interpretativa (GEERTZ, 1989) na educação escolar indígena junto aos professores indígenas Guarani das Aldeias de Boa Esperança e Três Palmeiras (2009-2010) e professores indígenas Tupinikim da Aldeia de Comboios (2011-2013) na perspectiva de um diálogo intercultural. Contribuem nos processos investigativos para produção, sistematização e análise de dados a realização de observações, entrevistas semiestruturadas, registros no caderno de campo, fotografias, gravações em áudio e em vídeo e análise documental sobre a educação escolar indígena de Aracruz. (ANDRÉ, 2007; GIL, 1999; 2004). Os resultados deste trabalho levantam questões relativas a duas realidades de educação escolar nas comunidades indígenas pesquisadas que se constituem em aspectos de sobrevivência e desencadeia formas para interagir e reagir em defesa de sua identidade e dignidade. Nesse sentido, a escola é um local de vivências e de encontro, vista e sentida pelas lideranças e pela comunidade como uma possibilidade real para desenvolver um elo entre as formas tradicionais de vida e as formas contemporâneas. O desafio de garantir uma escola nestes termos significa concretizar a proposta de um projeto de educação escolar para os povos indígenas, constituído por especificidades de como trabalhar a terra, pelo reconhecimento de suas tradições, das línguas e da memória coletiva. Distante de apresentar respostas conclusivas propõe uma educação escolar, coletiva e participativa, que critica e dialoga com todos os envolvidos no processo educativo.

Representing organizational structures in enterprise architecture : an ontology-based approach

Arquitetura Corporativa promove o estabelecimento de uma visão holística da estrutura e forma de trabalho de uma organização. Um dos aspectos abordados em Arquitetura Corporativa está associada a "estrutura ativa" da organização, que diz respeito a “quem" realiza as atividades organizacionais. Várias abordagens têm sido propostas a fim de proporcionar um meio para a representação de Arquitetura Corporativa, entre as quais ARIS, RM-ODP, UPDM e ArchiMate. Apesar da aceitação por parte da comunidade, as abordagens existentes se concentram em propósitos diferentes, têm limitações de escopo e algumas não têm semântica de mundo real bem definida. Além das abordagens de modelagem, muitas abordagens de ontologias têm sido propostas, a fim de descrever o domínio de estrutura ativa, incluindo as ontologias de SUPER Project, TOVE, Enterprise Ontology e W3C Org Ontology. Embora especificadas para fundamentação semântica e negociação de significado, algumas das abordagens propostas têm fins específicos e cobertura limitada. Além disso, algumas das abordagens não são definidas usando linguagens formais e outras são especificadas usando linguagens sem semântica bem definida. Este trabalho apresenta uma ontologia de referência bem fundamentada para o domínio organizacional. A ontologia organizacional de referência apresentada abrange os aspectos básicos discutidos na literatura organizacional, tais como divisão do trabalho, relações sociais e classificação das unidades estruturais. Além disso, também abrange os aspectos organizacionais definidos em abordagens existentes, levando em consideração tanto abordagens de modelagem quanto abordagens ontológicas. A ontologia resultante é especificada em OntoUML e estende os conceitos sociais de UFO-C.

The influence of nationalism in Mercosur and in South America: can the regional integration project survive?

The article discusses if nationalism is getting in the way of regional integration through a Brazilian prism due to Brazil’s pivotal role in regional integration in Mercosur and South America.

Sources of Brazil's Counter-Hegemony

There have been two key initiatives taken in the last two decades in Brazil to create a counter-hegemonic project for the country. One initiative resulted from Brazil's business community and high-level State bureaucracy and aimed at forming a regional economic and political bloc that would guarantee and enlarge a relative independence from the hegemonic powers. The other resulted from the emergence of the new unionist movement in São Paulo and from the formation of Partido dos Trabalhadores and aimed at promoting radical democratization and reducing social exclusion. Both initiatives have created policies and changes that have converged to enhance Brazil's counter-hegemonic position as a regional and emerging power.

A Digital Game Development Education Project

The success of the digital game industry is spawning several undergraduate degrees aiming at the training of digital game developers. Building adequate new courses curricula is not a trivial task and demands a profound analysis of the scientific areas to introduce as well as the dependencies throughout the entire degree. Another important aspect of every academic educational plan are the satellite projects that promote entrepreneurship and provide practical professional experiences to students. This paper presents the main guidelines adopted in the creation of the first digital game development undergraduate degree created in Portugal.

Information and Technology Implementation Issues in AAL Solutions

Therefore, it is presented features, scenarios and projects, referring the limitations and the opportunities for the future developments of prototypes using high level information and technology in AAL environments. Moreover, it is presented guidelines of operation, exposing the conceptual approach, and the discussion and conclusion, which present recommendations and current AAL4ALL project positions in terms of concepts and technologies.

Thermal skin reference values in healthy late pregnancy

Digital thermal imaging has been employed in medicine for over 50 years. However, its use has been focused on vascular, musculoskeletal and neurological conditions, while other potential applications,such as obstetrics, have been much less explored. This paper presents a study conducted during 2011 at the Hospital of Braga on a group of healthy pregnant women in the last third of gestation. The analysis focused on characterizing typical pregnant women steady temperature profiles in specific defined regions of interest (ROI), and determining if the thermal symmetry values for late pregnant healthy women are in line with the values for non-pregnant healthy women. A temperature distribution pattern was found in the defined ROI. The obtained thermal symmetry value had a maximum of 0.370.2 1C, and there was no evidence for the influence of age (p40.05) in the observed group. The influence of the BMI requires further investigation since one ROI (P2 right) presented a p¼0.059, close to the threshold of statistical evidence in the influence of BMI. The study group presented symmetry values in line with non-pregnant reference values, but the profiles in temperature distribution are different. Assumptions can therefore now be used with higher confidence when assessing abnormalities in specific pathologic states during pregnancy using the defined ROI. This work represents a first contribution towards establishing guidelines for future research in this specific field of study.

Ambient assisted living technology: comparative perspectives of users and caregivers

Developed societies are currently facing severe demographic changes: the world population is ageing at an unprecedented rate. This demographic trend will be also followed by an increase of people with physical limitations. New challenges are being raised to the traditional health care systems, not only in Portugal, but also in all other European states. There is an urgent need to find solutions that allow extending the time people can live in their preferred environment by increasing their autonomy, self-confidence and mobility. AAL4ALL is a project currently being developed in cooperation with 34 Portuguese interdisciplinary partners, from industry to academia, R&D and social disciplines, which employs a novel conceptual approach through the development of an ecosystem of products and services for Ambient Assisted Living (AAL) associated to a business model and validated through large scale trial. This paper presents a comparative perspective of the needs and attitudes towards technology of the AAL users and caregivers identified in the analysis of a set of three different surveys: a users survey targeted at the Portuguese seniors and pre-seniors; an informal caregivers survey targeted at the family, friends and neighbours who provide care without any financial compensation; and a formal caregivers survey targeted at physicians, nurses,psychologists, social workers, and direct-care workers providing care to elders. The first results indicate that AAL solutions must be affordable,user friendly and have a true perceived benefit to their users.

A Platform to Emulate Ambient Assisted Living Environments

According to the opinion of clinicians, emerging medical conditions can be timely detected by observing changes in the activities of daily living and/or in the physiological signals of a person. To accomplish such purpose, it is necessary to properly monitor both the person’s physiological signals as well as the home environment with sensing technology. Wireless sensor networks (WSNs) are a promising technology for this support. After receiving the data from the sensor nodes, a computer processes the data and extracts information to detect any abnormality. The computer runs algorithms that should have been previously developed and tested in real homes or in living-labs. However, these installations (and volunteers) may not be easily available. In order to get around that difficulty, this paper suggests the making of a physical model to emulate basic actions of a user at home, thus giving autonomy to researchers wanting to test the performance of their algorithms. This paper also studies some data communication issues in mobile WSNs namely how the orientation of the sensor nodes in the body affects the received signal strength, as well as retransmission aspects of a TDMA-based MAC protocol in the data recovery process.

Active Assistance for Senior Healthcare: A Wearable System for Fall Detection

Elders lose independence and wellbeing, accompanied by decreased functions in terms of hearing, vision, strength and coordination abilities. These factors contribute to balance difficulties that eventually lead to falls. The injuries due to falls, at this age, are risky, since most of the times may cause a significant – and permanent – decrease of quality of life or, in extreme cases, death. In this context, a fall detection system can bring an added value to assist elderly people.This paper describes a system consisting of a wearable sensor unit, a smartphone and a website. When the sensor detects a fall it sends an alert using the smartphone via Bluetooth 4.0, to notify the family members or stakeholders. The sensor device includes an inertial unit, a barometer, and a temperature and humidity sensor. The website displays the log of previous falls and enables the configuration of emergency contact numbers. The proposed fall detection system is one of multiple components within a larger project under development that offers a holistic perspective on falls; the complete wearable solution will also feature, among others, physical protection (minimizing the impact of falls that occur).
