Grupoterapia cognitivo-comportamental para crianças e adolescentes vítimas de abuso sexual

OBJETIVO: Avaliar os efeitos do modelo de grupoterapia cognitivo-comportamental para crianças e adolescentes do sexo feminino vítimas de abuso sexual. MÉTODOS: Foi utilizado delineamento não-randomizado intragrupos de séries temporais. Crianças e adolescentes do sexo feminino com idade entre nove e 16 anos (N=40) da região metropolitana de Porto Alegre (RS), foram clinicamente avaliadas em três encontros individuais, de 2006 a 2008. A grupoterapia consistiu de 16 sessões semi-estruturadas. Instrumentos psicológicos investigaram sintomas de ansiedade, depressão, transtorno do estresse pós-traumático, stress infantil e crenças e percepções da criança em relação à experiência abusiva antes, durante e após a intervenção. Os resultados foram analisados por meio de testes estatísticos para medidas repetidas. Foi realizada uma análise comparativa dos resultados do pré-teste entre os grupos que receberam atendimento psicológico em grupo imediato após a denúncia do abuso e aquelas que aguardaram por atendimento. RESULTADOS: A análise do impacto da intervenção revelou que a grupoterapia cognitivo-comportamental reduziu significativamente sintomas de depressão, ansiedade, stress infantil e transtorno do estresse pós-traumático. Além disso, a intervenção contribuiu para a reestruturação de crenças de culpa, baixa confiança e credibilidade, sendo efetivo para a redução de sintomas psicológicos e alteração de crenças e percepções distorcidas sobre o abuso. CONCLUSÕES: A grupoterapia cognitivo-comportamental mostrou ser efetiva para a redução de sintomas psicológicos de crianças e adolescentes vítimas de abuso sexual.

Cultural adaptation and psychometric properties of Brazilian Need for Recovery Scale

OBJECTIVE: To translate the Need for Recovery Scale (NFR) into Brazilian Portuguese and culturally adapt it and assess the stability, internal consistency and convergent validity of the Brazilian scale among industrial workers. METHODS: The translation process followed the guidelines for cultural adaptation of questionnaires including the steps of translation, synthesis, back translation, expert committee review, and pre-testing. The Brazilian Portuguese NFR, final version (Br-NFR) was assessed for stability (n=52) and internal consistency (n=192) and for convergent validity through simultaneous assessment with other instruments: the Borg Scale (n=59); the Chalder Fatigue Questionnaire (n=57) and 3 subscales of the SF-36 (n=56). RESULTS: Stability and internal consistency met the criterion for a reliable measure (ICC=0.80 and Cronbach's alpha =0.87, respectively). The convergent validity between Br-NFR and other instruments also showed good results: Borg Scale (r= 0.64); Chalder Questionnaire (r= 0.67); SF-36 subscales: vitality (r= -0.84), physical functioning (r= -0.54), and role-physical (r= -0.47). CONCLUSIONS: The Br-NFR proved to be a reliable instrument to evaluate work-related fatigue symptoms in industrial workers. Furthermore, it showed significant and good correlations with well-established instruments such as the Borg Scale, the Chalder Questionnaire and SF-36 vitality subscale, supporting the validity of the Br-NFR.

Use of negative information in positioning and tracking algorithms

To avoid additional hardware deployment, indoor localization systems have to be designed in such a way that they rely on existing infrastructure only. Besides the processing of measurements between nodes, localization procedure can include the information of all available environment information. In order to enhance the performance of Wi-Fi based localization systems, the innovative solution presented in this paper considers also the negative information. An indoor tracking method inspired by Kalman filtering is also proposed.

Índice de alimentação saudável para gestantes: adaptação para uso em gestantes brasileiras

OBJETIVO: Avaliar a qualidade global da dieta em uma amostra de gestantes, a partir de um parâmetro único, simples e objetivo. MÉTODOS: Gestantes entre a 16ª e 36ª semana de gestação (n = 712) foram arroladas em unidades básicas de saúde em Porto Alegre e Bento Gonçalves, RS, em 2010. Com base no índice americano Alternate Healthy Eating Index for Pregnancy (AHEI-P) foi criado o Índice de Alimentação Saudável para Gestantes Brasileiras (HEIP-B). Foram aplicados o questionário de frequência alimentar e o questionário sociodemográfico. Foi utilizada a análise de componentes principais focada para avaliar a relação entre os índices e os nutrientes relevantes à gestação. RESULTADOS: A mediana e o intervalo interquartílico dos índices AHEI-P e HEIP-B foram 66,6 (57,8-72,4) e 67,4 (60,0-73,4), respectivamente. O HEIP-B mostrou boa correlação positiva com os nutrientes que têm recomendação específica no período gestacional folato (r = 0,8; p < 0,001), cálcio (r = 0,6; p < 0,001) e ferro (r = 0,7; p < 0,001). CONCLUSÕES: A qualidade da dieta das gestantes do presente estudo foi classificada dentro do ponto de corte "precisando de melhorias", o que mostra a necessidade de se trabalhar mais especificamente com educação alimentar nesse ciclo da vida. O índice aplicado mostrou boas correlações e, portanto, pode ser considerado um bom instrumento de avaliação da qualidade da alimentação durante a gestação.

QoS-enabled middleware for smart grids

Emerging smart grid systems must be able to react quickly and predictably, adapting their operation to changing energy supply and demand, by controlling energy consuming and energy storage devices. An intrinsic problem with smart grids is that energy produced from in-house renewable sources is affected by fluctuating weather factors. The applications driving smart grids operation must rely on a solid communication network that is secure, highly scalable, and always available. Thus, any communication infrastructure for smart grids should support its potential of producing high quantities of real-time data, with the goal of reacting to state changes by actuating on devices in real-time, while providing Quality of Service (QoS).

Consumo alimentar e fatores dietéticos envolvidos no processo saúde e doença de Nikkeis: revisão sistemática

OBJETIVO: Analisar consumo alimentar e fatores dietéticos envolvidos no processo saúde e doença da população de nikkeis.MÉTODOS: Foi realizada revisão sistemática da literatura, com buscas nas bases de dados do Lilacs, SciELO e PubMed/Medline, referente ao período de 1997 a 2012, de estudos observacionais sobre o consumo alimentar de nikkeis. Inicialmente, foram analisados 137 títulos e resumos, sendo excluídos estudos de intervenção, aqueles que apresentavam somente níveis séricos de vitaminas e metabólitos e estudos que não contemplassem o objetivo da revisão. Desses, foram selecionados 38 estudos avaliados com base no método de Downs & Black (1998), adaptado para estudos observacionais, permanecendo 33 para análise.RESULTADOS: Foram encontrados poucos estudos sobre consumo alimentar de nikkeis fora do Havaí, dos Estados Unidos e do estado de São Paulo (principalmente em Bauru), no Brasil. Houve elevada contribuição dos lipídios no valor calórico total dos nipo-brasileiros, em detrimento dos carboidratos e das proteínas. Nos Estados Unidos, a prevalência de consumo de alimentos de alta densidade energética foi elevada em nipo-americanos. Os nisseis (filhos de imigrantes) apresentaram, em média, maior consumo de produtos da dieta japonesa, enquanto os sanseis (netos de imigrantes) apresentaram um perfil alimentar mais ocidentalizado.CONCLUSÕES: O consumo alimentar de nikkeis, embora ainda conservando alguns hábitos alimentares de japoneses nativos, revela alta prevalência de consumo de alimentos típicos do padrão ocidental (alimentos processados, ricos em gorduras e sódio e pobres em fibras), que pode estar contribuindo para o aumento de doenças crônicas nessa população.

ENCOURAGE architecture: support for heterogeneous smart grids

Our society relies on energy for most of its activities. One application domain inciding heavily on the energy budget regards the energy consumption in residential and non-residential buildings. The ever increasing needs for energy, resulting from the industrialization of developing countries and from the limited scalability of the traditional technologies for energy production, raises both problems and opportunities. The problems are related to the devastating effects of the greenhouse gases produced by the burning of oil and gas for energy production, and from the dependence of whole countries on companies providing gas and oil. The opportunities are mostly technological, since novel markets are opening for both energy production via renewable sources, and for innovations that can rationalize energy usage. An enticing research effort can be the mixing of these two aspects, by leveraging on ICT technologies to rationalize energy production, acquisition, and consumption. The ENCOURAGE project aims to develop embedded intelligence and integration technologies that will directly optimize energy use in buildings and enable active participation in the future smart grid environment.The primary application domains targeted by the ENCOURAGE project are non-residential buildings (e.g.: campuses) and residential buildings (e.g.: neighborhoods). The goal of the project is to achieve 20% of energy savings through the improved interoperability between various types of energy generation, consumption and storage devices; interbuilding energy exchange; and systematic performance monitoring.

Resistance of Aedes aegypti to temephos and adaptive disadvantages

OBJECTIVE To evaluate the resistance of Aedes aegypti to temephos Fersol 1G (temephos 1% w/w) associated with the adaptive disadvantage of insect populations in the absence of selection pressure. METHODS A diagnostic dose of 0.28 mg a.i./L and doses between 0.28 mg a.i./L and 1.40 mg a.i./L were used. Vector populations collected between 2007 and 2008 in the city of Campina Grande, state of Paraíba, were evaluated. To evaluate competition in the absence of selection pressure, insect populations with initial frequencies of 20.0%, 40.0%, 60.0%, and 80.0% resistant individuals were produced and subjected to the diagnostic dose for two months. Evaluation of the development of aquatic and adult stages allowed comparison of the life cycles in susceptible and resistant populations and construction of fertility life tables. RESULTS No mortality was observed in Ae. aegypti populations subjected to the diagnostic dose of 0.28 mg a.i./L. The decreased mortality observed in populations containing 20.0%, 40.0%, 60.0%, and 80.0% resistant insects indicates that temephos resistance is unstable in the absence of selection pressure. A comparison of the life cycles indicated differences in the duration and viability of the larval phase, but no differences were observed in embryo development, sex ratio, adult longevity, and number of eggs per female. CONCLUSIONS The fertility life table results indicated that some populations had reproductive disadvantages compared with the susceptible population in the absence of selection pressure, indicating the presence of a fitness cost in populations resistant to temephos.

Convergence to the European Energy Policy in European countries: case studies and comparison

Purpose – Our paper aims at analyzing how different European countries cope with the European Energy Policy, which proposes a set of measures (free energy market, smart meters, energy certificates) to improve energy utilization and management in Europe. Design/methodology/approach – The paper first reports the general vision, regulations and goals set up by Europe to implement the European Energy Policy. Later on, it performs an analysis of how some European countries are coping with the goals, with financial, legal, economical and regulatory measures. Finally, the paper draws a comparison between the countries to present a view on how Europe is responding to the emerging energy emergency of the modern world. Findings – Our analysis on different use cases (countries) showed that European countries are converging to a common energy policy, even though some countries appear to be later than others In particular, Southern European countries were slowed down by the world financial and economical crisis. Still, it appears that contingency plans were put into action, and Europe as a whole is proceeding steadily towards the common vision. Research limitations/implications – European countries are applying yet more cuts to financing green technologies, and it is not possible to predict clearly how each country will evolve its support to the European energy policy. Practical implications – Different countries applied the concepts and measures in different ways. The implementation of the European energy policy has to cope with the resulting plethora of regulations, and a company proposing enhancement regarding energy management still has to possess robust knowledge of the single country, before being able to export experience and know-how between European countries. Originality/Value – Even though a few surveys on energy measures in Europe are already part of the state-of-the-art, organic analysis diagonal to the different topics of the European Energy Policy is missing. Moreover, this paper highlights how European countries are converging on a common view, and provides some details on the differences between the countries, thus facilitating parties interesting into cross-country export of experience and technology for energy management.

Adaptive offloading for infotainment systems

Infotainment applications in vehicles are currently supported both by the in-vehicle platform, as well as by user’s smart devices, such as smartphones and tablets. More and more the user expects that there is a continuous service of applications inside or outside of the vehicle, provided in any of these devices (a simple but common example is hands-free mobile phone calls provided by the vehicle platform). With the increasing complexity of ‘apps’, it is necessary to support increasing levels of Quality of Service (QoS), with varying resource requirements. Users may want to start listening to music in the smartphone, or video in the tablet, being this application transparently ‘moved’ into the vehicle when it is started. This paper presents an adaptable offloading mechanism, following a service-oriented architecture pattern, which takes into account the QoS requirements of the applications being executed when making decisions.

CANDi: context-aware node discovery for short-range cooperation

Multi-standard mobile devices are allowing users to enjoy higher data rates with ubiquitous connectivity. However, the benefits gained from multiple interfaces come at an expense—that being higher energy consumption in an era where mobile devices need to be energy compliant. One promising solution is the usage of short-range cooperative communication as an overlay for infrastructure-based networks taking advantage of its context information. However, the node discovery mechanism, which is pivotal to the bearer establishment process, still represents a major burden in terms of the total energy budget. In this paper, we propose a technology agnostic approach towards enhancing the MAC energy ratings by presenting a context-aware node discovery (CANDi) algorithm, which provides a priori knowledge towards the node discovery mechanism by allowing it to search nodes in the near vicinity at the ‘right time and at the right place’. We describe the different beacons required for establishing the cooperation, as well as the context information required, including battery level, modes, location and so on. CANDi uses the long-range network (WiMAX and WiFi) to distribute the context information about cooperative clusters (Ultra-wideband-based) in the vicinity. The searching nodes can use this context in locating the cooperative clusters/nodes, which facilitates the establishing of short-range connections. Analytical and simulation results are obtained, and the energy saving gains are further demonstrated in the laboratory using a customised testbed. CANDi saves up to 50% energy during the node discovery process, while the demonstrative testbed shows up to 75% savings in the total energy budget, thus validating the algorithm, as well as providing viable evidence to support the usage of short-range cooperative communications for energy savings.

Replication vs erasure coding in data centric storage for wireless sensor networks

In-network storage of data in wireless sensor networks contributes to reduce the communications inside the network and to favor data aggregation. In this paper, we consider the use of n out of m codes and data dispersal in combination to in-network storage. In particular, we provide an abstract model of in-network storage to show how n out of m codes can be used, and we discuss how this can be achieved in five cases of study. We also define a model aimed at evaluating the probability of correct data encoding and decoding, we exploit this model and simulations to show how, in the cases of study, the parameters of the n out of m codes and the network should be configured in order to achieve correct data coding and decoding with high probability.

Convergence of Smart Grid ICT architectures for the last mile

The evolution of the electrical grid into a smart grid, allowing user production, storage and exchange of energy, remote control of appliances, and in general optimizations over how the energy is managed and consumed, is also an evolution into a complex Information and Communication Technology (ICT) system. With the goal of promoting an integrated and interoperable smart grid, a number of organizations all over the world started uncoordinated standardization activities, which caused the emergence of a large number of incompatible architectures and standards. There are now new standardization activities which have the goal of organizing existing standards and produce best practices to choose the right approach(es) to be employed in specific smart grid designs. This paper follows the lead of NIST and ETSI/CEN/CENELEC approaches in trying to provide taxonomy of existing solutions; our contribution reviews and relates current ICT state-of-the-art, with the objective of forecasting future trends based on the orientation of current efforts and on relationships between them. The resulting taxonomy provides guidelines for further studies of the architectures, and highlights how the standards in the last mile of the smart grid are converging to common solutions to improve ICT infrastructure interoperability.
