Performance management in health centres: evidence from a field study

There has been a growing interest in research on performance measurement and management practices, which seems to reflect researchers’ response to calls for the need to increase the relevance of management accounting research. However, despite the development of the new public management literature, studies involving public sector organizations are relatively small compared to those involving business organizations and extremely limited when it comes to public primary health care organizations. Yet, the economic significance of public health care organizations in the economy of developed countries and the criticisms these organizations regularly face from the public suggests there is a need for research. This is particularly true in the case of research that may lead to improvement in performance measurement and management practices and ultimately to improvements in the way health care organizations use their limited resources in the provision of services to the communities. This study reports on a field study involving three public primary health care organisations. The evidence obtained from interviews and archival data suggests a performance management practices in these institutions lacked consistency and coherence, potentially leading to decreased performance. Hierarchical controls seemed to be very weak and accountability limited, leading to a lack of direction, low motivation and, in some circumstances to insufficient managerial abilities and skills. Also, the performance management systems revealed a number of weaknesses, which suggests that there are various opportunities for improvement in performance in the studied organisations.

Definition of MV Load Diagrams via Weighted Evidence Accumulation Clustering using Subsampling

A definition of medium voltage (MV) load diagrams was made, based on the data base knowledge discovery process. Clustering techniques were used as support for the agents of the electric power retail markets to obtain specific knowledge of their customers’ consumption habits. Each customer class resulting from the clustering operation is represented by its load diagram. The Two-step clustering algorithm and the WEACS approach based on evidence accumulation (EAC) were applied to an electricity consumption data from a utility client’s database in order to form the customer’s classes and to find a set of representative consumption patterns. The WEACS approach is a clustering ensemble combination approach that uses subsampling and that weights differently the partitions in the co-association matrix. As a complementary step to the WEACS approach, all the final data partitions produced by the different variations of the method are combined and the Ward Link algorithm is used to obtain the final data partition. Experiment results showed that WEACS approach led to better accuracy than many other clustering approaches. In this paper the WEACS approach separates better the customer’s population than Two-step clustering algorithm.

Determination of electricity consumers’ load profiles via weighted evidence accumulation clustering using subsampling

With the electricity market liberalization, the distribution and retail companies are looking for better market strategies based on adequate information upon the consumption patterns of its electricity consumers. A fair insight on the consumers’ behavior will permit the definition of specific contract aspects based on the different consumption patterns. In order to form the different consumers’ classes, and find a set of representative consumption patterns we use electricity consumption data from a utility client’s database and two approaches: Two-step clustering algorithm and the WEACS approach based on evidence accumulation (EAC) for combining partitions in a clustering ensemble. While EAC uses a voting mechanism to produce a co-association matrix based on the pairwise associations obtained from N partitions and where each partition has equal weight in the combination process, the WEACS approach uses subsampling and weights differently the partitions. As a complementary step to the WEACS approach, we combine the partitions obtained in the WEACS approach with the ALL clustering ensemble construction method and we use the Ward Link algorithm to obtain the final data partition. The characterization of the obtained consumers’ clusters was performed using the C5.0 classification algorithm. Experiment results showed that the WEACS approach leads to better results than many other clustering approaches.

A literacia digital como pré-requisito do acesso ao conhecimento: estudo numa população estudantil da licenciatura em Farmácia da ESTSP-IPP

Introdução: O uso das TIC, nomeadamente dos ambientes virtuais de aprendizagem, são uma possibilidade pedagógica promissora e atractiva pois permitem a construção de conhecimento e a interacção entre alunos, professores e tutores. Na perspectiva do estudante, compreende-se que, em contextos virtuais de aprendizagem a tendência é a de se valorizar cada vez mais a sua participação no processo de ensino e de aprendizagem. No entanto, para que seja possível a implementação de educação a distância é necessário que os estudantes, para além da motivação e da responsabilidade acrescida, possuam um conjunto de competências específicas para participar, efectivamente, num contexto virtual de aprendizagem. Nesse contexto, e para verificar se o uso das tecnologias no processo educacional é exequível, é necessário conhecer as competências digitais dos alunos da Licenciatura em Farmácia da Escola Superior de Tecnologia da Saúde do Porto. Métodos: O estudo é descritivo-transversal e permitiu a recolha de dados através do inquérito por questionário, previamente validado. A amostra em estudo foi retirada da população formada pelos 230 estudantes da Licenciatura de Farmácia, por um processo de amostragem não probabilística por conveniência, perfazendo um total de 52 indivíduos que frequentam o 2º ano. Apresentação de Resultados e Discussão: Os resultados permitiram concluir que os estudantes utilizam as TIC de forma variada mas normalmente em actividades de lazer. Em relação ao conhecimento e utilização das ferramentas da Web 2.0 concluí-se que, na generalidade, os estudantes não conhecem e não dominam a maioria das ferramentas da Web 2.0.Ou seja, os estudantes, mesmo com as suas habilidades e conhecimentos sobre tecnologia, principalmente em relação ao uso de computadores e da Internet, e conhecendo a importância destes recursos como simplificadores nos estudos, continuam a apresentar limitações, provavelmente devido a falta de informação ou a informações duvidosas provenientes de uma utilização incorrecta dos recursos. Estes resultados representam também um desafio, uma vez que caberá à Escola capacitar os estudantes na utilização de novas tecnologias, uma vez que, estas capacidades são cada vez mais solicitadas no mercado de trabalho, e serão primordiais para o sucesso do estudante numa formação a distância mediada por computador.

Residential property loans and performance during property price booms: evidence from European banks

Understanding the performance of banks is of the utmost relevance, because of the impact of this sector on economic growth and financial stability. Of all the different assets that make up a bank portfolio, the residential mortgage loans constitute one of its main. Using the dynamic panel data method, we analyse the influence of residential mortgage loans on bank profitability and risk, using a sample of 555 banks in the European Union (EU-15), over the period from 1995 to 2008. We find that banks with larger weights of residential mortgage loans show lower credit risk in good times. This result explains why banks rush to lend on property during booms due to the positive effects it has on credit risk. The results show further that credit risk and profitability are lower during the upturn in the residential property price cycle. The results also reveal the existence of a non-linear relationship (U-shaped marginal effect), as a function of bank’s risk, between profitability and the residential mortgage loans exposure. For those banks that have high credit risk, a large exposure of residential mortgage loans is associated with higher risk-adjusted profitability, through lower risk. For banks with a moderate/low credit risk, the effects of higher residential mortgage loan exposure on its risk-adjusted profitability are also positive or marginally positive.

VirtualECare: group support in collaborative networks organizations for digital homecare

Collaborative Work plays an important role in today’s organizations, especially in areas where decisions must be made. However, any decision that involves a collective or group of decision makers is, by itself complex, but is becoming recurrent in recent years. In this work we present the VirtualECare project, an intelligent multi-agent system able to monitor, interact and serve its customers, which are, normally, in need of care services. In last year’s there has been a substantially increase on the number of people needed of intensive care, especially among the elderly, a phenomenon that is related to population ageing. However, this is becoming not exclusive of the elderly, as diseases like obesity, diabetes and blood pressure have been increasing among young adults. This is a new reality that needs to be dealt by the health sector, particularly by the public one. Given this scenarios, the importance of finding new and cost effective ways for health care delivery are of particular importance, especially when we believe they should not to be removed from their natural “habitat”. Following this line of thinking, the VirtualECare project will be presented, like similar ones that preceded it. Recently we have also assisted to a growing interest in combining the advances in information society - computing, telecommunications and presentation – in order to create Group Decision Support Systems (GDSS). Indeed, the new economy, along with increased competition in today’s complex business environments, takes the companies to seek complementarities in order to increase competitiveness and reduce risks. Under these scenarios, planning takes a major role in a company life. However, effective planning depends on the generation and analysis of ideas (innovative or not) and, as a result, the idea generation and management processes are crucial. Our objective is to apply the above presented GDSS to a new area. We believe that the use of GDSS in the healthcare arena will allow professionals to achieve better results in the analysis of one’s Electronically Clinical Profile (ECP). This achievement is vital, regarding the explosion of knowledge and skills, together with the need to use limited resources and get better results.

The evidence of conventional physiotherapeutic interventions after exercise-induced muscle damage: systematic review and meta-analysis

Abstract Introduction: Exhaustive and/or unaccustomed exercise, mainly those involving eccentric muscle actions, induces temporary muscle damage, evidenced by Delayed Onset Muscle Soreness. Different strategies to recover the signs and symptoms of this myogenic condition have been studied by researchers, as a result a significant number of articles on this issue have been published. Purpose: A systematic review was conducted to assess the evidence of the physiotherapeutic interventions of exercise-induced muscle damage. Methods: The electronic data bases were searched, including MEDLINE (1996-2011), CINHAL (1982- 2011), EMBASE (1988-2011), PEDro (1950-2011), and SPORTDiscus (1985-2011). Systematic review was limited to randomized control trials (RCTs) studies, written in English or Portuguese, which included physiotherapeutic interventions, namely massage, cryotherapy, stretching and low-intensity exercise, on adult human subjects (18-60 years old) of either gender. Studies were excluded when the intervention could not be assessed independently. The methodological quality of RCTs was independently assessed with the PEDro Scale by three reviewers. Results: Thirty-three studies were included in the systematic review; eight analyzed the effects of the massage, ten analyzed the effects of the cryotherapy, eight the effect of stretching and seventeen focused low-intensity exercise intervention. The results suggest that massage is the most effective intervention and that there is inconclusive evidence to support the use of cryotherapy; whereas the other conventional, namely stretching and low-intensity exercise, there is no evidence to prove their efficacy. Conclusion: The results allow the conclusion that massage is the physiotherapeutic intervention that demonstrated to be the most effective in the relief of symptoms and signs of exercise-induced muscle damage, as a result, massage should still be used in the muscular recovery after sports activities.

XBRL: a linguagem digital das empresas

O movimento de afirmação eXtensible Business Reporting Language (XBRL), como padrão para a preparação e difusão dos relatórios financeiros e outras publicações empresariais, foi encabeçado pelo American lnstitute of Certified Public Accountants (AICPA) em conjunto com aproximadatnente outras 30 organizações. Desde o primeiro encontro internacional sobre a especificação XBRL, realizado em Nova York no mês de Outubro de 1999, que a lista de participantes se tem alargado incluindo proeminentes instituições financeiras, organizações profissionais de serviços, organizações profissionais de contabilidade e fornecedores de tecnologia sobrevindo, ao mesmo tempo, um incontável número de alianças e ligações. A XBRL é uma linguagem standard utilizada no ambiente da Internet cujo desenvolvimento permitirá obter uma informação de melhor qualidade, mais rápida, mais económica e mais eficaz, para o processo de criação e publicação de relatórios financeiros e empresariais. Neste artigo os autores apresentam, resumidamente, as vantagens referidas pela literatura para esta nova tecnologia, descrevem sumariamente as características técnicas da XBRL, traçam o seu percurso desde 1999 e analisam o potencial deste standard para Portugal, bem como a sua aplicação em diferentes áreas de investigação.

Áudio digital: uma abordagem ao áudio pela perspectiva de ensino

A sociedade contemporânea tem acompanhado a evolução da Internet, ligando cada vez mais pessoas que exigem mais dela a cada dia que passa e desencadeando uma proliferação tecnológica nunca antes observada. A utilização de recursos, como vídeo e áudio na Internet, tem ganho nos últimos anos um crescente interesse. No entanto, constata-se a carência ou falta de recursos educativos digitais na área do áudio, que sejam capazes de apresentar uma pedagogia eficiente face a um tema muito complexo e extenso, para todos aqueles que queiram aprender de forma mais aprofundada o áudio como componente de engenharia. Na internet, sites de vídeos como Youtube ensinam a usar software de edição de áudio como Audacity, conceitos sobre som e áudio. Contudo, todos estão espalhados, sendo que a maior parte deles não possui fundamentos científicos ou uma bibliografia que acompanhe os conteúdos que leccionam. A proposta desta investigação é pesquisar sobre conhecimentos e recursos de áudio, integrando-os num produto Learning Object, Investigar noções teóricas sobre o som, equipamentos e técnicas usadas na área, assim como obter melhores resultados num espaço para a gravação que o aluno poderia fazer, aglomerando esses conceitos num protótipo mediamente desenvolvido. Foi necessária uma investigação extensa nesta área e avaliar e investigar a possibilidade de um recurso educativo, como o DALCH, capaz de proporcionar uma aprendizagem efectiva dos conceitos relacionados com áudio, que é um conceito complexo. Uma vez realizada essa investigação, foi necessário desenvolver, testar e avaliar um produto Learning Object, que apresentasse o áudio na sua globalidade, desde conceitos básicos até conceitos inerentes à própria produção. Foi possível aferir que esta solução pode contribuir para a formação desses alunos mediante uma experiência de aprendizagem agradável e intuitiva.

A compositional scheduling framework for digital avionics systems

ARINC specification 653-2 describes the interface between application software and underlying middleware in a distributed real-time avionics system. The real-time workload in this system comprises of partitions, where each partition consists of one or more processes. Processes incur blocking and preemption overheads and can communicate with other processes in the system. In this work we develop compositional techniques for automated scheduling of such partitions and processes. At present, system designers manually schedule partitions based on interactions they have with the partition vendors. This approach is not only time consuming, but can also result in under utilization of resources. In contrast, the technique proposed in this paper is a principled approach for scheduling ARINC-653 partitions and therefore should facilitate system integration.
