The role of coordination analysis in software integration projects

What sort of component coordination strategies emerge in a software integration process? How can such strategies be discovered and further analysed? How close are they to the coordination component of the envisaged architectural model which was supposed to guide the integration process? This paper introduces a framework in which such questions can be discussed and illustrates its use by describing part of a real case-study. The approach is based on a methodology which enables semi-automatic discovery of coordination patterns from source code, combining generalized slicing techniques and graph manipulation

Certification and integration of environment with quality and safety – a path to sustained success

According to Wright [1] certification of products and processes began during the 1960’s in the manufacturing industry, as a tool to control and assure the quality/conformity of products and services provided by suppliers to customers/consumers. Thus, the series of ISO 9000 was published first time, in 1987 and it was been created with a flexible character, to be reviewed periodically. Later, were published others normative references, which highlight the ISO 14001 in 1996 and OHSAS 18001 in 1999. This was also, the natural sequence of the certification processes in the organizations, i.e., began with the certification of quality management systems (QMS) followed by the environmental management systems (EMS) and after for the Occupational Health and Safety Management System (OHSMS). Hence, a high percentage of organizations with an EMS, in accordance with the ISO 14001, had also implemented, a certified QMS, in accordance with ISO 9001. At first the implementation of a QMS was particularly relevant in high demanding activity sectors, like the automotive and aeronautical industries, but it has rapidly extended to every activity sector, becoming a common requisite of any company worldwide and a factor of competitiveness and survival. Due to the increasingly demanding environmental legislation in developed countries, companies nowadays are required to seriously take into consideration not only environmental aspects associated to the production chain itself, but also to the life cycle of their products.

A generic model for integration of Quality, Environment and Safety Management Systems

Purpose – The purpose of this paper is to propose a generic model of Integrated Management System of Quality, Environment and Safety (IMS-QES) that can be adapted and progressively to assimilate various Management Systems, of which highlights: ISO 9001 for Quality; ISO 14001 for Environment; OHSAS 18001 for Occupational Health and Safety. Design/methodology/approach – The model was designed in the real environment of a Portuguese Organization and 160 employees were surveyed. The rate response was equal to 86 percent. The conceived model was implemented in a first phase for the integration of Quality, Environment and Safety Management Systems. Findings – Among the main findings of the survey the paper highlights: the elimination of conflicts between individual systems with resources optimization; creation of added value to the business by eliminating several types of wastes; the integrated management of sustainability components in a global market; the improvement of partnerships with suppliers of goods and services; reducing the number of internal and external audits. Originality/value – This case study is one of the first Portuguese empirical researches about IMS-QES and the paper believes that it can be useful in the creation of a Portuguese guideline for integration, namely the Quality Management Systems; Environmental Management Systems and Occupational Health and Safety Management Systems among others.

Integration of Individualized Management Systems (MSs) as an Aggregating Factor of Sustainable Value for Organizations: An Overview Through a Review of the Literature

Nowadays, there exist various standards for individual management systems (MSs), at least, one for each stakeholder. New ones will be published. An integrated management system (IMS) aims to integrate some or all components of the business into one coherent and efficient MS. Maximizing integration is more and more a strategic priority in that it constitutes an opportunity to eliminate and/or reduce potential factors of destruction of value for the organizations and also to be more competitive and consequently promote its sustainable success. A preliminary investigation was conducted on a Portuguese industrial company which, over the years, has been adopting gradually, in whole or in part, individualized management system standards (MSSs). A research, through a questionnaire, was performed with the objective to develop, in a real business environment, an adequate and efficient IMS-QES (quality, environment, and safety) model and to potentiate for the future a generic IMS model to integrate other MSSs. The strategy and research methods have taken into consideration the case study. It was obtained a set of relevant conclusions resulting from the statistical analyses of the responses to the survey. Globally, the investigation results, by themselves, justified and prioritized the conception of a model of development of the IMS-QES and consequent definition and validation of a structure of an IMS-QES model, to be implemented at the small- and medium-sized enterprise (SME) where the investigation was conducted.

Developments regarding the integration of the occupational safety and health with quality and environment management systems

Nanotechnology is the manipulation of matter on na almost atomic scale to produce new structures, materials, and devices. As potential occupational exposure to nanomaterials (NMs) becomes more prevalente, it is importante that the principles of medical surveillance and risk management be considered for workers in the nanotechnology industry.However, much information about health risk is beyond our current knowledge. Thus, NMs presente new challenges to understanding, predicting, andmanageing potential health risks. First, we briefly describe some general features of NMs and list the most importante types of NMs. This review discusses the toxicological potential of NMs by comparing possible injury mechanism and know, or potentially adverse, health effects. We review the limited research to date for occupational exposure to these particles and how a worker might be exposed to NMs. The principles of medical surveillance are reviewed to further the discussion of occupational health surveillance are reviewed to further the discussion of occupational health surveillance for workers exposed to NMs. We outlinehow occupational health professionals could contribute to a better knowledge of health effects by the utilization of a health surveillance program and by minimizing exposure. Finally, we discuss the early steps towards regulation and the difficulties facing regulators in controlling potentially harmful exposures in the absence of suficiente scientific evidence.

Integration of risk management in occupational health and safety systems

Risk management can be considered as part of the Occupational Health and Safety System (OHS) of an organization and can be used to develop and implement the OHS policy and manage the associated risks. The success of the integration of risk management in OHS depends on both technical and human aspects. Thus, this paper presents and discusses the case of a company working in the area of solid waste treatment. This company was certified in 2009 with an Integrated Management Systems for Quality, Environment, Occupational Health and Safety. The evolution of accidents before and after the implementation of the integrated system was analysed and a questionnaire was used to capture the perceptions of the technicians on the risk management system. The analysis of the findings showed that the frequency of accidents increased since 2009 but the severity has been reduced. Several interrelated causes and consequences were analysed and discussed. Furthermore, the analysis of the opinions of the company’s technicians permitted to highlight some important aspects on the integration of risk management in the OHS system of the company. In line with this discussion some hypothesis have been formulated.

Integration of Standardized Management Systems: A Dilemma?

Abstract: The growing proliferation of management systems standards (MSSs), and their individualized implementation, is a real problem faced by organizations. On the other hand, MSSs are aimed at improving efficiency and effectiveness of organizational responses in order to satisfy the requirements, needs and expectations of the stakeholders. Each organization has its own identity and this is an issue that cannot be neglected; hence, two possible approaches can be attended. First, continue with the implementation of individualized management systems (MSs); or, integrate the several MSSs versus related MSs into an integrated management system (IMS). Therefore, in this context, organizations are faced with a dilemma, as a result of the increasing proliferation and diversity of MSSs. This paper takes into account the knowledge gained through a case study conducted in the context of a Portuguese company and unveils some of the advantages and disadvantages of integration. A methodology is also proposed and presented to support organizations in developing and structuring the integration process of their individualized MSs, and consequently minimize problems that are generators of inefficiencies, value destruction and loss of competitiveness. The obtained results provide relevant information that can support Top Management decision in solving that dilemma and consequently promote a successful integration, including a better control of business risks associated to MSSs requirements and enhancing sustainable performance, considering the context in which organizations operate.

Integration of management systems: towards a sustained success and development of organizations

Effective environmental management within companies, integrated with other management areas like quality and occupational health and safety, is nowadays assumed to be a strategic way to implement and improve lean and cleaner production. Also, sustainable development (SD) and business sustainability can be achieved through a better coordinated management of processes versus associated resources. This paper presents an in depth discussion regarding the promotion of integrated management systems, their benefits and major contribution towards the sustainable development of cleaner production related features. It addresses issues regarding the contributions resulting from the integration of standardized Management System (MS) from both internal and external perspectives. Complementing the overall review of aspects to the development of integrated management systems a survey was conducted in order to better understand the relevance of the identified success factors. The main findings in this paper are as follows: a contextualization model of sustainable development and integrated management systems considering the Triple Bottom Line: economic, social and environmental; and, a method and associated model to support the development of integrated management systems as well as general guidelines to support integration. It can be concluded that a proactive approach and commitment to cleaner production, supported by an integrated management system, brings relevant savings for organizations as well as providing value to the relevant interested parties.

Metamorfoses em espelho de água : identidade, perfil, contextos e mudança nas (auto)representações dos professores

RESUMO: Nos últimos trinta anos, em Portugal, ocorreram processos de democratização política e de modernização da sociedade e das instituições, tendo como impulso as vontades nacionais e as mudanças ocorridas no Mundo em globalização, lideradas, no campo da educação, por agentes como a OCDE ou o Banco Mundial, e pela integração de Portugal na União Europeia. À implementação da(s) reforma(s), correspondeu uma mudança de paradigma educativo e organizacional, a criação de uma escola para todos, a emergência de novos alunos e de novos mandatos à Escola, a contingência de novas respostas educativas. Tais reformas constituiram instrumentos de mudança das organizações escolares e do sistema educativo, mas também do que significa ser professor, reformulando o desempenho e a “performatividade” docente (Ball, 2002), induzindo uma nova “identidade social” (Bernstein, 1996 e Dubar, 2006), produzindo novos modos de “fabricação da alma dos professores” (Foucault, 1996). Neste sentido, a autora procurou analisar, numa perspectiva crítica, as representações de professores do Ensino Básico, sobre os mecanismos de (re)configuração das suas identidades/perfis profissionais, recorrendo a uma investigação qualitativa descritiva, que privilegia a análise de conteúdo dos seus discursos sobre o tema, recolhidos segundo a técnica focus group. O estudo indiciou que os alunos são factor de realização, de risco e de mudança do perfil docente, actuando como uma quinta dimensão da (re)construção identitária dos Professores, a par da formação, do associativismo, do Estado e do Mercado, constituindo factor importante a ter em conta nos estudos sobre identidade docente. ABSTRACT: In the past thirty years, in Portugal, radical changes on politics and policies have been occurring, to achive the society and its institutions democratization and modernization, led by national wills and the changes occured in the World, stimulated, in the Education area, by global agencies like OECD, or the World Bank, and the integration of Portugal in the European Union. These reforms are connected to a new educational and organizational paradigm, the creation of a school for all, the emergence of new pupils, new demands to School and teachers, the imperative of new pedagogical solutions for educational problems, and are not only changing instruments in schools and in the educational system, but are also a powerful way to change “what to be a teacher” means, to re-formulate the teaching performance and “performativity” (Ball, 2002), to recompose his/her “social identity” (Bernstein, 1996; Dubar, 2006), or, in Michel Foucault (1996) words, to produce “new ways to manufacture teachers soul”. In this sense, the author intended to analyze, on a critical perspective, the representations of portuguese teachers of basic education (K12), on the mechanisms of (re)configuration of their professional identities/profiles, appealing to a qualitative descriptive research, which privileges the analysis of content of their speeches on the subject, collected according to the focus group technique, what, in its development, was brought near a circle of culture (in the sense of Paulo Freire‟s pedagogy). At least, pupils are the most important references and motivation to teachers changes, reflecting professional satisfaction and well done, but also risk, acting like a fifth dimension of teachers identity (re)construction, together with training, associative involvement, State and Market, and they must be considered on teatching identity studies.

Percursos e identidades. A (re)construção da identidade profissional do docente de enfermagem: o olhar dos docentes

RESUMO: Considerando a identidade como um processo dinâmico de interacção social, afastando-nos da ideia de identidades pré-estabelecidas, ancoradas numa visão essencialista e, aproximando-nos de uma identidade profissional que se constrói através de sucessivas interacções, procurámos conhecer a identidade profissional do docente de enfermagem. Convictos de que o estudo da identidade pode oscilar entre um pólo individual e um estrutural, optámos pela dimensão biográfica como eixo estruturante deste trabalho. Efectuaram-se oito biografias a docentes integrados no conceito de perito com uma profissionalidade reflectida. Utilizámos ainda o focus group como método complementar. Constatámos que os actores deste estudo se sentem enfermeiros, embora a sua área de actuação seja a docência. Destacam a integração do ensino de enfermagem no ensino superior como determinante na mudança da sua representação social. Todos estes docentes se incluem nos grupos que apresentam um estatuto da identidade realizado ou outorgado. Das competências que devem estar presentes no docente de enfermagem, salientam-se a comunicação, actualização científica e relação, capazes de promover um ambiente que propicie as aprendizagens significativas, de internacionalização, de investigação, como um modelo de conduta a seguir, que participe na vida da organização e seja capaz de motivar o outro, mas sobretudo que seja um bom enfermeiro. ABSTRACT: Considering identity as a social dynamic integration process, departing from the concept of pre-established identities anchored in an essentialist vision, and approaching a professional identity built trough successive interaction, we aimed to know the professional identity of the nursing teacher. Believing that the identity study may oscillate between an individual and a structural pole, we have chosen the biographic dimension as the structural axis for this assignment. Eight biographies from teachers integrated in the expert with a reflective professional identity have been made. We have also used the focus group as a complementary method. We have seen that the actors of this study feel themselves as nurses although their working area is teaching. They point out the higher teaching of Nursing as a determinant in the change of their social representation. All of these teachers are included in the groups that present an identity status that has been fulfilled or attributed. From the skills that should be present in the nursing teacher, communication, scientific knowledge and relationship are indicated when these are able to provide significant learning, internationalization and research as a behaviour model to be followed regarding the life of the organization and that might incentive others, but above as a way to be a good nurse.

Sistemas de informação: message integration bus

O trabalho apresentado por este documento aborda os problemas que advêm da necessidade de integração de aplicações, desenvolvidas em diferentes instantes no tempo, por diferentes equipas de trabalho, que para enriquecer os processos de negócio necessitam de comunicar entre si. A integração das aplicações tem de ser feita de forma opaca para estas, sendo disponibilizada por uma peça de software genérica, robusta e sem custos para as equipas desenvolvimento, na altura da integração. Esta integração tem de permitir que as aplicações comuniquem utilizando os protocolos que desejarem. Este trabalho propõe um middleware orientado a mensagens como solução para o problema identificado. A solução apresentada por este trabalho disponibiliza a comunicação entre aplicações que utilizam diferentes protocolos, permite ainda o desacoplamento temporal, espacial e de sincronismo na comunicação das aplicações. A implementação da solução tem base num sistema publish/subscribe orientado ao conteúdo e tem de lidar com as maiores exigências computacionais que este tipo de sistema acarta, sendo que a utilização deste se justifica com o enriquecimento da semântica de subscrição de eventos. Esta implementação utiliza uma arquitectura semi-distribuída, com o objectivo de aumentar a escalabilidade do sistema. A utilização da arquitectura semi-distribuída implica que a implementação da solução tem de lidar com o encaminhamento de eventos e divulgação das subscrições, pelos vários servidores de eventos. A implementação da solução disponibiliza garantias de persistência, processamento transaccional e tolerância a falhas, assim como transformação de eventos entre os diversos protocolos. A extensibilidade da solução é conseguida à custa de um sistema de pluggins que permite a adição de suporte a novos protocolos de comunicação. Os protocolos suportados pela implementação final do trabalho são RestMS e TCP.

Grid Integration of Offshore Wind Farms Using Modular Marx Multilevel Converters

This paper proposes the use of a Modular Marx Multilevel Converter, as a solution for energy integration between an offshore Wind Farm and the power grid network. The Marx modular multilevel converter is based on the Marx generator, and solves two typical problems in this type of multilevel topologies: modularity and dc capacitor voltage balancing. This paper details the strategy for dc capacitor voltage equalization. The dynamic models of the converter and power grid are presented in order to design the converter ac output voltages and the dc capacitor voltage controller. The average current control is presented and used for power flow control, harmonics and reactive power compensation. Simulation results are presented in order to show the effectiveness of the proposed (MC)-C-3 topology.

A Service Integration Platform for Collaborative Networks

Integrated manufacturing constitutes a complex system made of heterogeneous information and control subsystems. Those subsystems are not designed to the cooperation. Typically each subsystem automates specific processes, and establishes closed application domains, therefore it is very difficult to integrate it with other subsystems in order to respond to the needed process dynamics. Furthermore, to cope with ever growing marketcompetition and demands, it is necessary for manufacturing/enterprise systems to increase their responsiveness based on up-to-date knowledge and in-time data gathered from the diverse information and control systems. These have created new challenges for manufacturing sector, and even bigger challenges for collaborative manufacturing. The growing complexity of the information and communication technologies when coping with innovative business services based on collaborative contributions from multiple stakeholders, requires novel and multidisciplinary approaches. Service orientation is a strategic approach to deal with such complexity, and various stakeholders' information systems. Services or more precisely the autonomous computational agents implementing the services, provide an architectural pattern able to cope with the needs of integrated and distributed collaborative solutions. This paper proposes a service-oriented framework, aiming to support a virtual organizations breeding environment that is the basis for establishing short or long term goal-oriented virtual organizations. The notion of integrated business services, where customers receive some value developed through the contribution from a network of companies is a key element.

Virtual power producers integration into MASCEM

All over the world Distributed Generation is seen as a valuable help to get cleaner and more efficient electricity. Under this context distributed generators, owned by different decentralized players can provide a significant amount of the electricity generation. To get negotiation power and advantages of scale economy, these players can be aggregated giving place to a new concept: the Virtual Power Producer. Virtual Power Producers are multi-technology and multi-site heterogeneous entities. Virtual Power Producers should adopt organization and management methodologies so that they can make Distributed Generation a really profitable activity, able to participate in the market. In this paper we address the integration of Virtual Power Producers into an electricity market simulator –MASCEM – as a coalition of distributed producers.

Balancing market integration in MASCEM electricity market simulator

With the restructuring of the energy sector in industrialized countries there is an increased complexity in market players’ interactions along with emerging problems and new issues to be addressed. Decision support tools that facilitate the study and understanding of these markets are extremely useful to provide players with competitive advantage. In this context arises MASCEM, a multi-agent simulator for competitive electricity markets. It is essential to reinforce MASCEM with the ability to recreate electricity markets reality in the fullest possible extent, making it able to simulate as many types of markets models and players as possible. This paper presents the development of the Balancing Market in MASCEM. A key module to the study of competitive electricity markets, as it has well defined and distinct characteristics previously implemented.
