Developing a knowledge-based perspective on coordination:the case of global software projects

We have attempted to bring together two areas which are challenging for both IS research and practice: forms of coordination and management of knowledge in the context of global, virtual software development projects. We developed a more comprehensive, knowledge-based model of how coordination can be achieved, and\illustrated the heuristic and explanatory power of the model when applied to global software projects experiencing different degrees of success. We first reviewed the literature on coordination and determined what is known about coordination of knowledge in global software projects. From this we developed a new, distinctive knowledge-based model of coordination, which was then employed to analyze two case studies of global software projects, at SAP and Baan, to illustrate the utility of the model.

INFRAWEBS Semantic Web Service Development on the Base of Knowledge Management Layer

The paper gives an overview about the ongoing FP6-IST INFRAWEBS project and describes the main layers and software components embedded in an application oriented realisation framework. An important part of INFRAWEBS is a Semantic Web Unit (SWU) – a collaboration platform and interoperable middleware for ontology-based handling and maintaining of SWS. The framework provides knowledge about a specific domain and relies on ontologies to structure and exchange this knowledge to semantic service development modules. INFRAWEBS Designer and Composer are sub-modules of SWU responsible for creating Semantic Web Services using Case-Based Reasoning approach. The Service Access Middleware (SAM) is responsible for building up the communication channels between users and various other modules. It serves as a generic middleware for deployment of Semantic Web Services. This software toolset provides a development framework for creating and maintaining the full-life-cycle of Semantic Web Services with specific application support.

Classificação de técnicas e auxílio à navegação de busca com base em sua carga cognitiva, precisão e eficiência

Navigation, in both virtual and real environments, is the process of a deliberated movement to a specific place that is usually away from the origin point, and that cannot be perceived from it. Navigation aid techniques (TANs) have as their main objective help finding a path through a virtual environment to a desired location and, are widely used because they ease the navigation on these unknown environments. Tools like maps, GPS (Global Positioning System) or even oral instructions are real world examples of TAN usage. Most of the works which propose new TANs for virtual environments aim to analyze their impact in efficiency gain on navigation tasks from a known place to an unknown place. However, such papers tend to ignore the effect caused by a TAN usage over the route knowledge acquisition process, which is important on virtual to real training transfer, for example. Based on a user study, it was possible to confirm that TANs with different strategies affects the performance of search tasks differently and that the efficiency of the help provided by a TAN is not inversely related to the cognitive load of the technique’s aids. A technique classification formula was created. This formula utilizes three factors instead of only efficiency. The experiment’s data were applied to the formula and we obtained a better refinement of help level provided by TANs.

A Framework to Capture and Share Knowledge Using Storytelling and Video Sharing in Global Product Development

In global engineering enterprises, information and knowledge sharing are critical factors that can determine a project’s success. This statement is widely acknowledged in published literature. However, according to some academics, tacit knowledge is derived from a person’s lifetime of experience, practice, perception and learning, which makes it hard to capture and document in order to be shared. This project investigates if social media tools can be used to improve and enable tacit knowledge sharing within a global engineering enterprise. This paper first provides a brief background of the subject area, followed by an explanation of the industrial investigation, from which the proposed knowledge framework to improve tacit knowledge sharing is presented. This project’s main focus is on the improvement of collaboration and knowledge sharing amongst product development engineers in order to improve the whole product development cycle.

Development of a knowledge sharing framework for improving the testing processes in global product development

As identified by Griffin (1997) and Kahn (2012), manufacturing organisations typically improve their market position by accelerating their product development (PD) cycles. One method for achieving this is to reduce the time taken to design, test and validate new products, so that they can reach the end customer before competition. This paper adds to existing research on PD testing procedures by reporting on an exploratory investigation carried out in a UK-based manufacturing plant. We explore the organisational and managerial factors that contribute to the time spent on testing of new products during development. The investigation consisted of three sections, viz. observations and process modelling, utilisation metrics and a questionnaire-based investigation, from which a proposed framework to improve and reduce the PD time cycle is presented. This research focuses specifically on the improvement of the utilisation of product testing facilities and the links to its main internal stakeholders - PD engineers.

The relationship between personal cognition, social context, and knowledge sharing in global communities of practice

The purpose of this study was to identify the structural pathways of personal cognition and social context as they influence knowledge sharing behaviors in communities of practice. Based on the existing literature, ten hypotheses and a conceptual model built on the basis of the social cognitive theory were developed regarding the interrelationships of the five constructs: self-efficacy for knowledge sharing, outcome expectations, sense of community, leadership of a community, and knowledge sharing. The data were collected through an online questionnaire from the employees who have participated in communities of practice in a Fortune 100 corporation. A total of 438 usable questionnaires were collected. Overall, three analyses were conducted in order to prove the given hypotheses: (a) hypothesized measurement model fit, (b) relational and influential associations among the constructs, and (c) structural equation model analysis (SEM). In addition, open-ended responses were analyzed. The results presented that (a) hypothesized measurement models were valid and reliable, (b) personal cognitive factors, self-efficacy and outcome expectations for knowledge sharing, were found to be significant predictors of community members’ sense of community and knowledge sharing behaviors, (c) sense of community had the most significant impact on the knowledge sharing, (d) as the perceived social context, sense of community mediated the effects of personal cognition on knowledge sharing behaviors, and (e) personal cognition and social context jointly contributed to knowledge sharing. In brief, all of the hypotheses were positively supported. A conclusive summary is provided along with contributive discussion. Implications and contributions to HRD researchers and practitioners are discussed, and recommendations are provided.

O treino como meio de desenvolvimento global do atleta : relatório de estágio em futebol realizado na equipa de juniores do Grupo Desportivo Alcochetense, 1ª Divisão Distrital da AF Setúbal, época 2014- 2015

No dia a dia de uma equipa, muitos são os fatores que influenciam o seu funcionamento e a sua construção. Uma constante adaptação ao contexto envolvente e à evolução em termos de conhecimento científico, são fatores determinantes no trabalho de um treinador. Desta forma, possuindo mais e melhores ferramentas de trabalho, permitir-lhe-á maximizar a aprendizagem e o rendimento dos seus jogadores. Neste relatório, pretende-se apresentar, analisar e refletir sobre a conceção e implementação das atividades práticas durante toda a época desportiva da equipa de Juniores do Grupo Desportivo Alcochetense, Para além da parte ligada às várias áreas do treino, este relatório irá abranger outras áreas de grande importância na vida de um treinador, sendo elas a área de Inovação e Investigação (Área 2) e a Relação com a Comunidade (Área 3). Com base na análise do contexto e nos objetivos definidos para a equipa, descrevemos e fundamentamos o modelo de jogo criado pela equipa técnica, assim como o planeamento definido para a época desportiva. Através de uma categorização dos exercícios de treino, foi possível fazer uma quantificação do volume de treino de cada categoria, o que permitiu perceber quais os conteúdos mais abordados durante toda a época desportiva. Na área 2 do estágio, procuramos aprofundar o conhecimento em torno da inclusão do trabalho físico complementar como meio de prevenção de lesões no processo de treino de uma equipa de futebol e a relação que este pode ter no desempenho desportivo. Embora não tenha sido possível proceder à sua aplicação prática, parece clara a importância deste tipo de abordagem no treino de uma equipa de futebol. Como tal, apresentamos uma proposta de protocolo de treino de prevenção de lesões. No âmbito da área 3, partindo da necessidade da comunidade de treinadores de futebol em manter uma formação teórica continua, foram organizadas duas ações de formação, em parceria com o Núcleo de Lisboa da Associação Nacional de Treinadores de Futebol, sobre a temática da Organização Estrutural do Exercício em Futebol e sobre as Bases para a construção de uma equipa de Futebol.

Risk premiumin the global creditMarkets: 2006-2012

¿What have we learnt from the 2006-2012 crisis, including events such as the subprime crisis, the bankruptcy of Lehman Brothers or the European sovereign debt crisis, among others? It is usually assumed that in firms that have a CDS quotation, this CDS is the key factor in establishing the credit premiumrisk for a new financial asset. Thus, the CDS is a key element for any investor in taking relative value opportunities across a firm’s capital structure. In the first chapter we study the most relevant aspects of the microstructure of the CDS market in terms of pricing, to have a clear idea of how this market works. We consider that such an analysis is a necessary point for establishing a solid base for the rest of the chapters in order to carry out the different empirical studies we perform. In its document “Basel III: A global regulatory framework for more resilient banks and banking systems”, Basel sets the requirement of a capital charge for credit valuation adjustment (CVA) risk in the trading book and its methodology for the computation for the capital requirement. This regulatory requirement has added extra pressure for in-depth knowledge of the CDS market and this motivates the analysis performed in this thesis. The problem arises in estimating of the credit risk premium for those counterparties without a directly quoted CDS in the market. How can we estimate the credit spread for an issuer without CDS? In addition to this, given the high volatility period in the credit market in the last few years and, in particular, after the default of Lehman Brothers on 15 September 2008, we observe the presence of big outliers in the distribution of credit spread in the different combinations of rating, industry and region. After an exhaustive analysis of the results from the different models studied, we have reached the following conclusions. It is clear that hierarchical regression models fit the data much better than those of non-hierarchical regression. Furthermore,we generally prefer the median model (50%-quantile regression) to the mean model (standard OLS regression) due to its robustness when assigning the price to a new credit asset without spread,minimizing the “inversion problem”. Finally, an additional fundamental reason to prefer the median model is the typical "right skewness" distribution of CDS spreads...

Envelhecimento e deficiência auditiva referida: um estudo de base populacional

O objetivo do estudo foi estimar a prevalência da deficiência auditiva referida por idosos do Município de São Paulo, Brasil, segundo características sociodemográficas e descrever características atribuídas a esta deficiência. Os dados são provenientes do Inquérito de Saúde do Município de São Paulo (ISA-Capital/2003), com análise do subgrupo dos idosos (n = 872). Realizaram-se o teste do χ2 e a análise de regressão de Poisson. A prevalência da deficiência auditiva referida pelos idosos foi 11,2% e foi maior entre os homens (RP = 1,86; IC95%: 1,19-2,92). Observou-se grande desconhecimento dos idosos quanto às causas da deficiência auditiva referida (42,5%), 25,5% relataram ter dificuldades em atividades de lazer, 11,4% necessitavam de ajuda para atividades cotidianas e 63,3% relataram não necessitar de assistência em decorrência deste déficit. A alta prevalência de deficiência auditiva referida pelos idosos, principalmente do sexo masculino, remete à relevância deste problema para a saúde pública, já que o envelhecimento populacional é uma realidade nova e vem acompanhada de exigências ainda desconhecidas por profissionais e pelo poder público.

Fatores associados à prática de atividade física global e de lazer em idosos: Inquérito de Saúde no Estado de São Paulo (ISA-SP), Brasil

The purpose of this study was to measure the prevalence of global and leisure-time physical activity and associated factors in the elderly. This was a population-based cross-sectional study covering a multiple-stage sample of 1,950 subjects 60 years or older living in areas of São Paulo State, Brazil. Prevalence of global physical activity (assessed through the short version of the International Physical Activity Questionnaire - IPAQ) was 73.9%, and prevalence of leisure-time physical activity was 28.4%. The results highlight the differences between factors associated with global and leisure-time physical activities. The social groups most prone to overall sedentary lifestyle and especially to lack of leisure-time physical activity should be the main targets of health policies aimed at promoting healthier lifestyles.

Validade científica de conhecimento epidemiológico gerado com base no estudo Saúde Bucal Brasil 2003

Problematiza-se a afirmação de que não são válidas as estimativas sobre as condições de saúde bucal da população brasileira geradas pelo SB Brasil 2003. Criticam-se os elementos que pretendem sustentar esse ponto de vista com base apenas em conceitos estatísticos, sem prova empírica. Identificam-se reduções decorrentes da abordagem epistemocêntrica que recusa peremptoriamente outras formas de conhecimento e não reconhece o caráter multidisciplinar da epidemiologia. Reconstituem-se informações sobre a realização do levantamento e seu impacto na produção de conhecimento. Faz-se uma analogia entre ciência e arte, argumentando-se que, nas imagens obtidas por ambas, os saberes gerados a partir do objeto cognoscível assumem feições variadas e, portanto, o reconhecimento de sua validade requer amplo domínio do objeto e operações com adequados critérios de valor. Conclui-se pela cientificidade, validade e relevância da produção acadêmica desenvolvida a partir da base de dados do levantamento SB Brasil 2003.

Global gene expression profile in myelodysplastic syndromes using SAGE

The molecular pathogenesis of myelodysplastic syndromes (MDS) is poorly understood. In order to expand our knowledge of genetic defects in MDS, we determined the overall profile of genes expressed in bone marrow from patients with refractory anemia with excess blasts ( RAEB) by serial analysis of gene expression ( SAGE). The present report describes a partial transcriptome of RAEB bone marrow derived from 56,694 sequenced tags that provides information about expressed gene products. This is the first attempt to determine an overall profile of gene expression specifically in RAEB at diagnosis using SAGE, which should be useful in the understanding of the physiopathology of MDS and in identifying the genes involved.
