A perspective on LCA application in site remediation services: critical review of challenges

The remediation of contaminated sites supports the goal of sustainable development but may also have environmental impacts at a local, regional and global scale. Life cycle assessment (LCA) has increasingly been used in order to support site remediation decision-making. This review article discusses existing LCA methods and proposed models focusing on critical decisions and assumptions of the LCA application to site remediation activities. It is concluded that LCA has limitations as an adequate holistic decisionmaking tool since spatial and temporal differentiation of non-global impacts assessment is a major hurdle in site remediation LCA. Moreover, a consequential LCA perspective should be adopted when the different remediation services to be compared generate different site’s physical states, displacing alternative post-remediation scenarios. The environmental effects of the post-remediation stage of the site is generally disregarded in the past site remediation LCA studies and such exclusion may produce misleading conclusions and misdirected decision-making. In addition, clear guidance accepted by all stakeholders on remediation capital equipment exclusion and on dealing with multifunctional processes should be developed for site remediation LCA applications.

Direct medical costs associated with schizophrenia relapses in health care services in the city of São Paulo

OBJECTIVE: To assess direct medical costs associated with schizophrenia relapses in mental health services. METHODS: The study was conducted in three health facilities in the city of São Paulo: a public state hospital; a Brazilian National Health System (SUS)-contracted hospital; and a community mental health center. Medical records of 90 patients with schizophrenia who received care in 2006 were reviewed. Information on inpatient expenditures was collected and used for cost estimates. RESULTS: Mean direct medical cost of schizophrenia relapses per patient was US$ 4,083.50 (R$ 8,167.58) in the public state hospital; US$ 2,302.76 (R$ 4,605.46) in the community mental health center; and US$ 1,198.50 (R$ 2,397.74) in the SUS-affiliated hospital. The main component was daily inpatient room rates (87% - 98%). Medication costs varied depending on the use of typical or atypical antipsychotic drugs. Atypical antipsychotic drugs were more often used in the community mental health center. CONCLUSIONS: Costs associated with schizophrenia relapses support investments in antipsychotic drugs and strategies to reduce disease relapse and the need for mental health inpatient services. Treating patients in a community mental health center was associated with medium costs and added the benefit of not depriving these patients from family life.

The Interactions between clients and providers of services related to marketing activities

The purpose of this paper is to analyze the business interactions involved in the purchase of services related to marketing activities. We build on the literature about business services classifications and the interaction between clients and providers of business services. An empirical study is conducted by means of a survey questionnaire. Data were collected from a sample of 80 buying firms of services related to marketing activities who agreed to cooperate and represent medium and large Portuguese’s firms. The results show that the buying of services related to marketing activities involves both the client and the provider in the interaction process. This paper contributes to understanding the interaction process of buying services related to marketing activities in terms of the parties involved, product/service exchange, financial and information exchange. Providers of services related to marketing activities can expect stable and preferred relationships if they can offer a good price and quality of service, meet the agreed deadlines and respond quickly to client orders. On the client’s side, the relevance, the characteristics and the wide diversity of services related to marketing activities requires a good understanding and management of the interaction portfolio with providers.

Sistema pericial para suporte à decisão na alocação de recursos de emergência

O panorama atual da emergência e socorro de primeira linha em Portugal, carateriza-se por uma grande aposta ao longo dos últimos anos num incremento contínuo da qualidade e da eficiência que estes serviços prestam às populações locais. Com vista à prossecução do objetivo de melhoria contínua dos serviços, foram realizados ao longo dos últimos anos investimentos avultados ao nível dos recursos técnicos e ao nível da contratação e formação de recursos humanos altamente qualificados. Atualmente as instituições que prestam socorro e emergência de primeira linha estão bem dotadas ao nível físico e ao nível humano dos recursos necessários para fazerem face aos mais diversos tipos de ocorrências. Contudo, ao nível dos sistemas de informação de apoio à emergência e socorro de primeira linha, verifica-se uma inadequação (e por vezes inexistência) de sistemas informáticos capazes de suportar convenientemente o atual contexto de exigência e complexidade da emergência e socorro. Foi feita ao longo dos últimos anos, uma forte aposta na melhoria dos recursos físicos e dos recursos humanos encarregues da resposta àsemergência de primeira linha, mas descurou-se a área da gestão e análise da informação sobre as ocorrências, assim como, o delinear de possíveis estratégias de prevenção que uma análise sistematizada da informação sobre as ocorrências possibilita. Nas instituições de emergência e socorro de primeira linha em Portugal (bombeiros, proteção civil municipal, PSP, GNR, polícia municipal), prevalecem ainda hoje os sistemas informáticos apenas para o registo das ocorrências à posteriori e a total inexistência de sistemas de registo de informação e de apoio à decisão na alocação de recursos que operem em tempo real. A generalidade dos sistemas informáticos atualmente existentes nas instituições são unicamente de sistemas de backoffice, que não aproveitam a todas as potencialidades da informação operacional neles armazenada. Verificou-se também, que a geo-localização por via informática dos recursos físicos e de pontos de interesse relevantes em situações críticas é inexistente a este nível. Neste contexto, consideramos ser possível e importante alinhar o nível dos sistemas informáticos das instituições encarregues da emergência e socorro de primeira linha, com o nível dos recursos físicos e humanos que já dispõem atualmente. Dado que a emergência e socorro de primeira linha é um domínio claramente elegível para a aplicação de tecnologias provenientes dos domínios da inteligência artificial (nomeadamente sistemas periciais para apoio à decisão) e da geo-localização, decidimos no âmbito desta tese desenvolver um sistema informático capaz de colmatar muitas das lacunas por nós identificadas ao nível dos sistemas informáticos destas instituições. Pretendemos colocar as suas plataformas informáticas num nível similar ao dos seus recursos físicos e humanos. Assim, foram por nós identificadas duas áreas chave onde a implementação de sistemas informáticos adequados às reais necessidades das instituições podem ter um impacto muito proporcionar uma melhor gestão e otimização dos recursos físicos e humanos. As duas áreas chave por nós identificadas são o suporte à decisão na alocação dos recursos físicos e a geolocalização dos recursos físicos, das ocorrências e dos pontos de interesse. Procurando fornecer uma resposta válida e adequada a estas duas necessidades prementes, foi desenvolvido no âmbito desta tese o sistema CRITICAL DECISIONS. O sistema CRITICAL DECISIONS incorpora um conjunto de funcionalidades típicas de um sistema pericial, para o apoio na decisão de alocação de recursos físicos às ocorrências. A inferência automática dos recursos físicos, assenta num conjunto de regra de inferência armazenadas numa base de conhecimento, em constante crescimento e atualização, com base nas respostas bem sucedidas a ocorrências passadas. Para suprimir as carências aos nível da geo-localização dos recursos físicos, das ocorrências e dos pontos de interesse, o sistema CRITICAL DECISIONS incorpora também um conjunto de funcionalidades de geo-localização. Estas permitem a geo-localização de todos os recursos físicos da instituição, a geo-localização dos locais e as áreas das várias ocorrências, assim como, dos vários tipos de pontos de interesse. O sistema CRITICAL DECISIONS visa ainda suprimir um conjunto de outras carências por nós identificadas, ao nível da gestão documental (planos de emergência, plantas dos edifícios) , da comunicação, da partilha de informação entre as instituições de socorro e emergência locais, da contabilização dos tempos de serviço, entre outros. O sistema CRITICAL DECISIONS é o culminar de um esforço colaborativo e contínuo com várias instituições, responsáveis pela emergência e socorro de primeira linha a nível local. Esperamos com o sistema CRITICAL DECISIONS, dotar estas instituições de uma plataforma informática atual, inovadora, evolutiva, com baixos custos de implementação e de operação, capaz de proporcionar melhorias contínuas e significativas ao nível da qualidade da resposta às ocorrências, das capacidades de prevenção e de uma melhor otimização de todos os tipos de recursos que têm ao dispor.

Orchestration of e-learning services for automatic evaluation of programming exercises

Managing programming exercises require several heterogeneous systems such as evaluation engines, learning objects repositories and exercise resolution environments. The coordination of networks of such disparate systems is rather complex. These tools would be too specific to incorporate in an e-Learning platform. Even if they could be provided as pluggable components, the burden of maintaining them would be prohibitive to institutions with few courses in those domains. This work presents a standard based approach for the coordination of a network of e-Learning systems participating on the automatic evaluation of programming exercises. The proposed approach uses a pivot component to orchestrate the interaction among all the systems using communication standards. This approach was validated through its effective use on classroom and we present some preliminary results.

Mixed integer non linear programming and artificial neural network based approach to ancillary services dispatch in competitive electricity markets

Ancillary services represent a good business opportunity that must be considered by market players. This paper presents a new methodology for ancillary services market dispatch. The method considers the bids submitted to the market and includes a market clearing mechanism based on deterministic optimization. An Artificial Neural Network is used for day-ahead prediction of Regulation Down, regulation-up, Spin Reserve and Non-Spin Reserve requirements. Two test cases based on California Independent System Operator data concerning dispatch of Regulation Down, Regulation Up, Spin Reserve and Non-Spin Reserve services are included in this paper to illustrate the application of the proposed method: (1) dispatch considering simple bids; (2) dispatch considering complex bids.

Stressful working conditions and poor self-rated health among financial services employees

OBJECTIVE: To assess the association between exposure to adverse psychosocial working conditions and poor self-rated health among bank employees. METHODS: A cross-sectional study including a sample of 2,054 employees of a government bank was conducted in 2008. Self-rated health was assessed by a single question: "In general, would you say your health is (...)." Exposure to adverse psychosocial working conditions was evaluated by the effort-reward imbalance model and the demand-control model. Information on other independent variables was obtained through a self-administered semi-structured questionnaire. A multiple logistic regression analysis was performed and odds ratio calculated to assess independent associations between adverse psychosocial working conditions and poor self-rated health. RESULTS: The overall prevalence of poor self-rated health was 9%, with no significant gender difference. Exposure to high demand and low control environment at work was associated with poor self-rated health. Employees with high effort-reward imbalance and overcommitment also reported poor self-rated health, with a dose-response relationship. Social support at work was inversely related to poor self-rated health, with a dose-response relationship. CONCLUSIONS: Exposure to adverse psychosocial work factors assessed based on the effort-reward imbalance model and the demand-control model is independently associated with poor self-rated health among the workers studied.

Position paper on time and event-triggered communication services in the context of e-manufacturing

Modern factories are complex systems where advances in networking and information technologies are opening new ways towards higher efficiency. Such move is being driven by market rules with ever-increasing competition levels, in search for faster time-to-market, improved process yield, non-stop operations, flexible manufacturing and tighter supply-chain coupling. All these aims present a common requirement, i.e. a realtime flow of information, from the plant-floor up to the management, maintenance, suppliers and clients, to support accurate monitoring and control of the factory. This stresses the importance achieved by the communication infrastructure in modern manufacturing industry. This paper presents the authors view concerning the current trends in modern factory communication systems. It addresses the problems of seamlessly integrating different information flows with diverse requirements, mainly in terms of timeliness. In this aspect, the debate between event-triggered and time-triggered communication is revisited as well as the joint support for both types of traffic. Finally, a view of where factory communication systems are moving to is also presented, showing the impact of open and widely available technologies.

QoS of IP services in a fieldbus network: on the limitations and possible improvements

This paper focuses on the problem of providing efficient scheduling mechanisms for IP packets encapsulated in the frames of a real-time fieldbus network - the PROFIBUS. The approach described consists on a dual-stack approach encompassing both the controlrelated traffic ("native" fieldbus traffic) and the IPrelated traffic. The overall goal is to maintain the hard real-time guarantees of the control-related traffic, while at the same time providing the desired quality of service (QoS) to the coexistent IP applications. We start to describe the work which have been up to now carried out in the framework of the European project RFieldbus (High Performance Wireless Fieldbus in Industrial Multimedia-Related Environments - IST-1999-11316). Then we identify its limitations and point out solutions that are now being addressed out of the framework of the above-mentioned European project.

Demo: automatic personal identification system for security in critical services: a case study

The demonstration proposal moves from the capabilities of a wireless biometric badge [4], which integrates a localization and tracking service along with an automatic personal identification mechanism, to show how a full system architecture is devised to enable the control of physical accesses to restricted areas. The system leverages on the availability of a novel IEEE 802.15.4/Zigbee Cluster Tree network model, on enhanced security levels and on the respect of all the users' privacy issues.

Services innovation and economic performance: An analysis at the firm

In this paper we estimate a model linking innovation effort and economic performance, along the lines of the Mairesse and Mohnen (2003) model. We examine this relationship in the context of services sectors instead of Research and Development intensive manufacturing sectors. Much effort has already been made to explore the innovation-performance relationship for manufacturing sectors but it is still much understudied for services, particularly for Portugal. In this paper we aim to take a step in fulfilling this gap. We use new firm level data for ten services sectors from the Second Community Innovation Survey of Portugal, to estimate the model.
