Domain-Specific Language for Coordination patterns

The integration and composition of software systems requires a good architectural design phase to speed up communications between (remote) components. However, during implementation phase, the code to coordinate such components often ends up mixed in the main business code. This leads to maintenance problems, raising the need for, on the one hand, separating the coordination code from the business code, and on the other hand, providing mechanisms for analysis and comprehension of the architectural decisions once made. In this context our aim is at developing a domain-specific language, CoordL, to describe typical coordination patterns. From our point of view, coordination patterns are abstractions, in a graph form, over the composition of coordination statements from the system code. These patterns would allow us to identify, by means of pattern-based graph search strategies, the code responsible for the coordination of the several components in a system. The recovering and separation of the architectural decisions for a better comprehension of the software is the main purpose of this pattern language

Capital Intelectual: sua divulgação no setor bancário em Portugal

The importance of intangible resources has increased dramatically in recent years comparing to tangible ones. The economy in which we live is the result of competitive pressures that have imposed the implementation of business at an international level as well as a requirement in the application of sophisticated technologies that allow us to follow this fast evolution. In this age of information and innovation organizations will only survive if they are inserted in a global network of strategic relations, generically called as the network economy by Lev (2003). The service sector has stood out against the more traditional sectors of the economy. The intensive use of knowledge and a strong customer orientation created a new reality in today’s organizations: a growing importance attached to innovation, to the quality of products and services offered, to the information and communication technologies adopted, and to the creativity and particular abilities of human resources. The concept of intangible assets is more common in an accounting language and intellectual capital is most often applied in the context of management, being associated with a more comprehensive, multidimensional approach, representing all the knowledge that the institution owns and that it applies in the form of expertise, the creativity and organizational competencies that lead to innovation and to the sustained attainment of future economic benefits. An analysis of the scope of intellectual capital is fundamental to take more appropriate management decisions so that a more appropriate accounting treatment could be given by the accounting standardization organizations. This study intends to analyse the practices of information disclosure of the intellectual capital in the banking sector in Portugal, complementing the analysis of the disclosure of intangible assets in the context of accounting standards with the disclosure of intellectual capital in the context of organizational management. In particular, our main aims are to identify the extent of disclosure of intellectual capital made by banks in Portugal and also to identify the factors that determine such a disclosure. The disclosure in the context of accounting standards will be studied by checking the disclosure of intangible assets through the items listed in the International Accounting Standard 38 developed by the International Accounting Standards Board. The context of management was analysed by means of creating a voluntary disclosure index based on assumptions of the model Intellectus, developed by the Centro de Investigación sobre la Sociedad del Conocimiento – Instituto de Administración de Empresas (CIC-IADE) of the Universidad Autónoma of Madrid, and of the model Intellectual Capital Statement (made in Europe) (InCaS), both promoted by the European Commission and that we have adapted to the banking sector. When analysing the disclosure of intangible assets based on the context of accounting standards and the voluntary disclosure of intellectual capital, this study has tried to raise awareness about the importance of issuing reports on the intellectual capital as an alternative tool to take management decisions in the existing organizations and reflects the transparency and legitimacy that these institutions seek through a more extensive and more detailed information disclosure of their intellectual capital. Based on a complimentarily of economic theories, together with social and political theories, we tried to check the extent, evolution and tendencies of the compulsory disclosure of intangible assets and of the voluntary disclosure of the intellectual capital analysed in the period 2001-2011. Banks characteristics were also analysed in order to deduce those factors that determine or promote a larger disclosure in this sector. Based on these objectives, we adopted a longitudinal approach to explore the extent and the development of the disclosure of intangible assets as well as the factors that have determined it. Furthermore, we sought to assess the impact of the adoption of IAS 38 in the financial statements of the organizations in this sector. The disclosure index created on the basis of the disclosure requirements stated in IAS 38 from IASB was applied to the consolidated financial statements of the seventeen banks that rendered their statements in Portugal from 2001 to 2009. Since the information disclosed in the context of accounting standards may not have an important role as a management tool once it was not able to reflect what really contributes to the competitiveness and organizational growth, the voluntary disclosure of the intellectual capital was analysed according to the information obtained from the 2010 annual individual reports of the banks operating in Portugal in that year and from their respective websites in 2011. We tried to analyse the extent of the voluntary disclosure of the intellectual capital and of each of its components, human capital, structural capital and relational capital. The comparative analysis of their annual reports and their web pages allowed us to assess the incidence of the disclosure and discover what channel the banking sector focuses on when disclosing their intellectual capital. Also in this analysis the study of the disclosure determinants has allowed us to conclude about the influence of particular characteristics in the voluntary disclosure of the intellectual capital. The results of the analysis to the extent of the disclosure of intangible assets in the consolidated financial statements of the banking groups in Portugal in the period 2001-2009 have shown an average information disclosure of 0.24. This information disclosure evolved from an average value of 0.1940 in 2001 to 0.2778 in 2009. The average value is 0.8286 if it is only considered the disclosure of the intangible assets that the banks possessed. The evolution of this index means an increase in the average disclosure from 0.7852 in 2001 to 0.8788 in 2009. From the first results that are related to the extent of the disclosure of intangible assets in the financial statements, we can verify that the banking groups present a low disclosure level of these resources. However, when considering the disclosure of only the intangible assets that each institution owns, the disclosure level appears to be in compliance with the disclosure requirements for this sector. An evolution in the disclosure of intangible assets for the period considered was confirmed, showing an increase in the information disclosure of intangible assets in 2005, the year in which the accounting rules for intangible assets changed. The analysis that focused on the disclosure in the context of management tried to understand the extent, the incidence and the determinants of the voluntary information disclosure of intellectual capital in the annual reports of 2010 and on their web pages in 2011, studying the 32 banks operating in Portugal in this period. The average voluntary disclosure of the intellectual capital in the 2010 annual reports is 0.4342 while that in web pages is 0.2907. A review of the components of the intellectual capital allowed us to assess the importance that the banks confer to each of these components. The data obtained show that the relational capital, and more specifically the business capital, is the most disclosed component by banks in Portugal both in the annual reports and in their institutional web pages, followed by the structural capital and, finally, by the human capital. The disclosure of the human capital and the structural capital is higher in the annual reports than that in the websites, while the relational capital is more disclosed in the websites than in the annual reports. The results have also shown that the banks make a complementary use of both sources when disclosing information about their structural capital and relational capital but they do not show any information about their human capital in their websites. We tried to prove the influence of factors that could determine the accounting disclosure and the voluntary disclosure of the intellectual capital in this sector. The change in the IASB accounting rules as from January 1st 2005 gave a greater disclosure of accounting information of intangible assets in the financial statements of banks. The bank size and corporate governance measures have statistically proved to have an influence on the extent of the accounting disclosure of intangible assets and on the voluntary disclosure of the intellectual capital. Economic and financial variables such as profitability, operating efficiency or solvency were not determinants of information disclosure. The instability that the banking sector has experienced in economic and financial indicators in recent years as a result of the global financial markets imbalance has worsen indicators such as profitability, efficiency and solvency and caused major discrepancies in the economic situation between banks in Portugal. This empirical analysis has contributed to confront the disclosure required by accounting rules performed in the financial statements of organizations with that performed in the main disclosure media which is available for entities and which is increasingly requested in the process of taking management decisions. It also allowed us to verify whether there is homogeneity between institutions in the fulfilment of the requirements for information disclosure of intangible assets. However, as for voluntary disclosure of intellectual capital, there are large disparities in the disclosure extent between organizations. Regardless of this sector specific characteristics, the voluntary disclosure of intellectual capital made by banks in Portugal follows the trends in other sectors and the practices adopted in other countries, namely regarding the amount of information disclosed, the incidence of the disclosure on the indicators of relational capital and the importance of variables such as size as determinants of disclosure of intellectual capital. For a further knowledge in this field, we created a specific index for the banking sector, considering appropriate indicators for an incisive, comprehensive analysis in order to consider the most relevant indicators of intellectual capital components. Besides, confronting the analysis of disclosure in the context of accounting standards with the study of voluntary disclosure brought a new analysis approach to the research on intellectual capital disclosure. With this study, we have also intended to raise greater awareness of the need for harmonization in the intellectual capital disclosure on the part of the regulatory banking authority by means of a demanding, consistent and transparent report of intellectual capital with simple, clear, objective indicators so that those interested in disclosing intellectual capital information in the organizations in this sector may obtain more harmonized and comparable information. A research on the disclosure quality of intellectual capital, together with the application of other analysis methodologies in this sector, might be a promising approach for future research. Applying the voluntary disclosure index to the same sector in other countries may also contribute to the knowledge of disclosure practices in different geographical environments. We highlight the relevance of further studies contributing to the harmonization and consistency in the presentation of an intellectual capital report so as to enable organizations to disclose the resources that contribute most to their competitiveness and growth.

A incubação das micro, pequenas e médias empresas (MPMEs) em Portugal : uma discussão sobre custos de transacção, dimensão competitiva e a cadeia de valor

RESUMO: Este trabalho tem por objectivo discutir as formas como as incubadoras de empresas contribuem para a criação da cadeia de valores de Micros, Pequenas e Médias Empresas (MPMEs) permitindo a redução dos seus custos de transacção. Para melhor compreender a forma como se reduzem os custos de transacção é importante conhecer os pressupostos comportamentais que provocam a existência de tais custos: a racionalidade limitada, porque a nossa forma de pensar tem limitações; e o oportunismo, porque há pessoas com comportamentos desonestos envolvidas no negócio. O verdadeiro poder explicativo da teoria dos custos de transacção está, no entanto, na análise de três variáveis que determinam se esses custos serão mais baixos numa estrutura hierárquica ou num mercado. Estas três variáveis são: a especificidade de activos - se uma transacção envolve ou não activos específicos à actividade da empresa; a incerteza - qual o grau de incerteza em encontrar um produto ou serviço externo à empresa; e a frequência - e se um bem ou serviço é frequentemente utilizado ou não. As incubadoras de empresas são actualmente consideradas como uma iniciativa essencial ao desenvolvimento socioeconómico regional, e nacional. Estas instituições contribuem para corrigir ineficiências no mercado, conferindo às empresas uma capacidade de inovação tecnológica que garante empregos e a criação de riquezas, aumentando o bem-estar da sociedade. O sucesso da sua actuação resume-se à capacidade para gerar dimensões virtuais que contribuem para a cadeia de valores, permitindo as MPMEs, a redução dos seus custos de transacção. ABSTRACT: This work aims to discuss the relevant forms how incubators contribute to the value chain of a in micro, small and medium enterprises (MSME´s) reducing their transaction costs. To better understand how transaction costs can be reduced one must recognize the behavioral assumptions that are behind there existence; bounded rationality - because our way of thinking has limitations and opportunism - because there are dishonest people involved in the business. The true cost theory´s explanatory power comes from the analyses of the three variables that determine whether those costs will be lower in a hierarchical structure or a market structure. These three variables are: specificity of assets - if the transaction involves or not specific assets in for the firm´s activity; the uncertainty - what is the degree of uncertainty in finding a product or service external to the firm; and the frequency - what is the frequency of the good or service use. Business incubators are currently regarded as a key initiative for the national or regional economic development. The institutions contribute to correct market inefficiencies, improving the capacity of firms to produce technological innovations that guaranty jobs and wealth creation increasing welfare. The success of this all boils down to the capacity to create virtual dimensions that contributes to the MSME´s value chain reducing transaction costs.

Fatores críticos no comportamento do gestor público responsável por compras sustentáveis: diferenças entre consumo individual e organizacional

O presente artigo investiga o comportamento de gestores públicos, identificando os fatores críticos que determinam o processo decisório de compra sustentável, seja no contexto de compras individuais (ou domésticas) ou no contexto de compras organizacionais (nesse caso, refere-se às compras públicas sustentáveis, conceito recentemente inserido na legislação brasileira). Em seguida à aplicação de questionários a um grupo de gestores públicos encarregados da elaboração de editais e condução de certames licitatórios, foram realizadas inferências estatísticas que determinaram as similitudes entre os dois contextos. A partir dos resultados, observou-se diferenças relacionadas com o contexto de compra envolvido, em especial naquelas que envolvem preço, determinações da legislação e tempo gasto nas especificações dos produtos a serem adquiridos. Chamam atenção, ademais, o fato de que alguns padrões pró-ambientais se mostram bem estabelecidos, evidenciado o resultado de campanhas desenvolvidas no âmbito da instituição.

An approach to absorptive capacity based on the Portuguese textile industry

The main purpose of this research is to identify the hidden knowledge and learning mechanisms in the organization in order to disclosure the tacit knowledge and transform it into explicit knowledge. Most firms usually tend to duplicate their efforts acquiring extra knowledge and new learning skills while forgetting to exploit the existing ones thus wasting one life time resources that could be applied to increase added value within the firm overall competitive advantage. This unique value in the shape of creation, acquisition, transformation and application of learning and knowledge is not disseminated throughout the individual, group and, ultimately, the company itself. This work is based on three variables that explain the behaviour of learning as the process of construction and acquisition of knowledge, namely internal social capital, technology and external social capital, which include the main attributes of learning and knowledge that help us to capture the essence of this symbiosis. Absorptive Capacity provides the right tool to explore this uncertainty within the firm it is possible to achieve the perfect match between learning skills and knowledge needed to support the overall strategy of the firm. This study has taken in to account a sample of the Portuguese textile industry and it is based on a multisectorial analysis that makes it possible a crossfunctional analysis to check on the validity of results in order to better understand and capture the dynamics of organizational behavior.

Informação da dosimetria individual pelas organizações de saúde

A aplicação das radiações ionizantes na área da medicina tem vindo a crescer desde o século passado. Na área da medicina, existem três especialidades principais que desenvolvem as suas actividades recorrendo à aplicação de radiações ionizantes, no âmbito do diagnóstico e da terapêutica: a Medicina Nuclear, a Radiologia e a Radioterapia. Salienta-se uma quarta área, a Cardiopneumologia quando actua na cardiologia de intervenção. Segundo o Decreto-Lei nº 222/2008, de 17/11, cabe às Organizações de Saúde (OSs) a responsabilidade de assegurar a monitorização individual dos trabalhadores expostos a radiações ionizantes, a monitorização dos locais de trabalho e a vigilância médica dos trabalhadores expostos. No que respeita à monitorização individual dos profissionais, as OSs determinam qual e empresa que procederá ao fornecimento e leitura dos dosímetros, não esquecendo no momento da contratação o Decreto-Lei nº 222/2008, de 17/11, artigo 10, que salienta que a monitorização individual dos trabalhadores da categoria A deve ter uma periodicidade mensal, assim como as leituras de dosimetria individual também devem ser mensais. Todos os profissionais têm o direito de aceder a todos os dados referentes à sua monitorização individual das doses de radiação, incluindo os resultados das medições, individuais ou de área que levaram à estimação das doses recebidas. O objectivo geral deste estudo é verificar se as OSs notificam/informam os profissionais de saúde expostos a radiações ionizantes das leituras de dosimetria individual e com que periodicidade.

Antinomias e "suturas" epistemológicas entre biológico-social e individual-coletivo no âmbito da epidemiologia social

A complexidade do objeto epidemiológico tem suscitado, ao longo do tempo, discussão sobre alguns elementos que o compõem, assumindo, muitas vezes, a forma de antinomias. Utilizando-se como substrato textos fundamentais, analisaram-se, no âmbito da epidemiologia social, a formulação e a proposta de solução para as antinomias biológico-social e individual-coletivo. Criticou-se a validade teórica das saídas apontadas pelo discurso epidemiológico-social para resolver o "conflito de leis" que permeia o referido objeto. Destacou-se o conceito marxista-helleriano de indivíduo para contribuir com a "sutura" dos três planos da realidade: o universal, o particular e o singular.

Human cryptosporidiosis: detection of specific antibodies in the serum by an indirect immunofluorescence

Cryptosporidium sp., a coccidian parasite usually found in the faeces of cattle, has been recently implicated as an agent of human intestinal disease, mainly in immunocompromised patients. In the study realized, by an indirect immunofluorescence technique, specific immunoglobulins (IgG and IgM) have been demonstrated in human serum against Cryptosporidium oocysts. Purified oocysts were used as antigens in the indirect immunofluorecence assay. After analyzing this test in sera from selected groups of patients, the frequency of both specific IgG and IgM of immunocompetent children who were excreting oocysts in their faeces was 62% and in children with negative excretion of oocysts was 20% and 40%, respectively. In adults infected with the human immunodeficiency virus (HIV) and who were excreting Cryptosporidium in their stools, the frequency was 57% for IgG but only 2% for IgM. Twenty three percent of immunocompromised adults with not determined excretion of oocysts in their stools had anti-Cryptosporidium IgG in their sera. Children infected with human immunodeficiency virus had no IgM and only 14% had IgG detectable in their sera. The indirect immunoflorescence assay, when used with other parasitological techniques appears to be useful for retrospective population studies and for diagnosis of acute infection. The humoral immune response of HIV positive patients to this protozoan agent needs clarification.

A hybrid approach to multi-agent decision-making

In the aftermath of a large-scale disaster, agents' decisions derive from self-interested (e.g. survival), common-good (e.g. victims' rescue) and teamwork (e.g. fire extinction) motivations. However, current decision-theoretic models are either purely individual or purely collective and find it difficult to deal with motivational attitudes; on the other hand, mental-state based models find it difficult to deal with uncertainty. We propose a hybrid, CvI-JI, approach that combines: i) collective 'versus' individual (CvI) decisions, founded on the Markov decision process (MDP) quantitative evaluation of joint-actions, and ii)joint-intentions (JI) formulation of teamwork, founded on the belief-desire-intention (BDI) architecture of general mental-state based reasoning. The CvI-JI evaluation explores the performance's improvement

Individual pension information: Recommendations for the case of Spain based on the experiences of other countries

The aim of this paper is to establish some basic guidelines to help draft the information letter sent to individual contributors should it be decided to use this model in the Spanish public pension system. With this end in mind and basing our work on the experiences of the most advanced countries in the field and the pioneering papers by Jackson (2005), Larsson et al. (2008) and Sunden (2009), we look into the concept of “individual pension information” and identify its most relevant characteristics. We then give a detailed description of two models, those in the United States and Sweden, and in particular look at how they are structured, what aspects could be improved and what their limitations are. Finally we make some recommendations of special interest for designing the model for Spain.
