A competing values framework approach on growth and performance in micro firms

This study aims to analyze and compare four micro-firms' organizational culture, evaluated through the Competing Values Framework (Quinn & Rohbaugh, 1983). Data was collected in 2011 and 2013 in firms selling the same type of software and providing the same kind of services, focusing on the years between 2008-2011. Findings point to somewhat different results of micro-firms, when comparing to other samples in the literature. Suggestions for future research are given.

Industrie 4.0 Framework, Challenges and Perspectives

The world is increasingly in a global community. The rapid technological development of communication and information technologies allows the transmission of knowledge in real-time. In this context, it is imperative that the most developed countries are able to develop their own strategies to stimulate the industrial sector to keep up-to-date and being competitive in a dynamic and volatile global market so as to maintain its competitive capacities and by consequence, permits the maintenance of a pacific social state to meet the human and social needs of the nation. The path traced of competitiveness through technological differentiation in industrialization allows a wider and innovative field of research. Already we are facing a new phase of organization and industrial technology that begins to change the way we relate with the industry, society and the human interaction in the world of work in current standards. This Thesis, develop an analysis of Industrie 4.0 Framework, Challenges and Perspectives. Also, an analysis of German reality in facing to approach the future challenge in this theme, the competition expected to win in future global markets, points of domestic concerns felt in its industrial fabric household face this challenge and proposes recommendations for a more effective implementation of its own strategy. The methods of research consisted of a comprehensive review and strategically analysis of existing global literature on the topic, either directly or indirectly, in parallel with the analysis of questionnaires and data analysis performed by entities representing the industry at national and world global placement. The results found by this multilevel analysis, allowed concluding that this is a theme that is only in the beginning for construction the platform to engage the future Internet of Things in the industrial environment Industrie 4.0. This dissertation allows stimulate the need of achievements of more strategically and operational approach within the society itself as a whole to clarify the existing weaknesses in this area, so that the National Strategy can be implemented with effective approaches and planned actions for a direct training plan in a more efficiently path in education for the theme.

Parallel Software framework for time-critical many-core systems

The recent technological advancements and market trends are causing an interesting phenomenon towards the convergence of High-Performance Computing (HPC) and Embedded Computing (EC) domains. On one side, new kinds of HPC applications are being required by markets needing huge amounts of information to be processed within a bounded amount of time. On the other side, EC systems are increasingly concerned with providing higher performance in real-time, challenging the performance capabilities of current architectures. The advent of next-generation many-core embedded platforms has the chance of intercepting this converging need for predictable high-performance, allowing HPC and EC applications to be executed on efficient and powerful heterogeneous architectures integrating general-purpose processors with many-core computing fabrics. To this end, it is of paramount importance to develop new techniques for exploiting the massively parallel computation capabilities of such platforms in a predictable way. P-SOCRATES will tackle this important challenge by merging leading research groups from the HPC and EC communities. The time-criticality and parallelisation challenges common to both areas will be addressed by proposing an integrated framework for executing workload-intensive applications with real-time requirements on top of next-generation commercial-off-the-shelf (COTS) platforms based on many-core accelerated architectures. The project will investigate new HPC techniques that fulfil real-time requirements. The main sources of indeterminism will be identified, proposing efficient mapping and scheduling algorithms, along with the associated timing and schedulability analysis, to guarantee the real-time and performance requirements of the applications.

SHõWA: A Self-healing Framework for Web-based Applications

The complexity of systems is considered an obstacle to the progress of the IT industry. Autonomic computing is presented as the alternative to cope with the growing complexity. It is a holistic approach, in which the systems are able to configure, heal, optimize, and protect by themselves. Web-based applications are an example of systems where the complexity is high. The number of components, their interoperability, and workload variations are factors that may lead to performance failures or unavailability scenarios. The occurrence of these scenarios affects the revenue and reputation of businesses that rely on these types of applications. In this article, we present a self-healing framework for Web-based applications (SHõWA). SHõWA is composed by several modules, which monitor the application, analyze the data to detect and pinpoint anomalies, and execute recovery actions autonomously. The monitoring is done by a small aspect-oriented programming agent. This agent does not require changes to the application source code and includes adaptive and selective algorithms to regulate the level of monitoring. The anomalies are detected and pinpointed by means of statistical correlation. The data analysis detects changes in the server response time and analyzes if those changes are correlated with the workload or are due to a performance anomaly. In the presence of per- formance anomalies, the data analysis pinpoints the anomaly. Upon the pinpointing of anomalies, SHõWA executes a recovery procedure. We also present a study about the detection and localization of anomalies, the accuracy of the data analysis, and the performance impact induced by SHõWA. Two benchmarking applications, exercised through dynamic workloads, and different types of anomaly were considered in the study. The results reveal that (1) the capacity of SHõWA to detect and pinpoint anomalies while the number of end users affected is low; (2) SHõWA was able to detect anomalies without raising any false alarm; and (3) SHõWA does not induce a significant performance overhead (throughput was affected in less than 1%, and the response time delay was no more than 2 milliseconds).

Knowledge repository framework for crowdsourcing innovation intermediary: a proposal

A crowdsourcing innovation intermediary performs mediation activities between companies that have a problem to solve or that seek a business opportunity, and a group of people motivated to present ideas based on their knowledge, experience and wisdom, taking advantage of technology sharing and collaboration emerging from Web2.0. As far as we know, most of the present intermediaries don´t have, yet, an integrated vision that combines the creation of value through community development, brokering and technology transfer. In this paper we present a proposal of a knowledge repository framework for crowdsourcing innovation that enables effective support and integration of the activities developed in the process of value creation (community building, brokering and technology transfer), modeled using ontology engineering methods.

Plano estratégico “Empowering Lab ESEIG”

Os jovens ao longo do seu percurso escolar têm aspirações e expetativas elevadas quanto ao valor de empregabilidade dos diplomas a que tiveram acesso em todos os graus de ensino. Contudo, no recente contexto de crise económica, essas aspirações e expetativas socialmente nutridas pela escola e pela família têm sido em grande medida frustradas pelas crescentes dificuldades que os jovens portugueses de hoje têm vivido nos seus processos de inserção profissional. A nível individual, um jovem que passe um longo período inativo tem grandes probabilidades de sofrer de baixa autoestima, exclusão social ou de um “wage scar”, isto é, de no futuro ter um rendimento abaixo do rendimento médio de pessoas com formação e experiência equivalentes além de desenvolverem uma atitude passiva e falta de participação social, o que no longo prazo acaba por ter implicações negativas para a sociedade como um todo. Conscientes desta realidade e sabendo que as incubadoras de negócios podem transmitir confiança à comunidade financeira e apoiar as startups, promovendo uma cultura de empreendedorismo e agindo como um catalisador para o desenvolvimento de estruturas de suporte de negócios mais amplas, partimos para o estudo da incubação de negócios com o intuito de traçar um plano estratégico para a Escola Superior de Estudos Industriais e de Gestão (ESEIG) que permitisse desenvolver a cultura empreendedora da sua comunidade e por esta via dar o seu contributo para a resolução da crise económica que o país atravessa. Começamos por fazer um enquadramento teórico da incubação de negócios e rapidamente percebemos que, sendo a ESEIG uma instituição de ensino superior, era importante incluir no estudo os conceitos de empreendedorismo e inovação e perceber ao nível teórico como funciona a relação Universidade-Empresa. De seguida, fomos para o “terreno” e percebemos que a solução para este desafio passaria por capacitar os alunos da ESEIG com as competências empresariais e empreendedoras necessárias para o desenvolvimento de qualquer empreendimento autonomamente. Faltava agora perceber qual a melhor forma de concretizar este ambicioso objetivo. Após um pouco mais de estudo, percebemos que, a paixão está no centro de empreendedorismo juntamente com outras dimensões afetivas e emocionais e pode estimular a criatividade e o reconhecimento de novos padrões de informação fundamental para a descoberta e exploração de oportunidades promissoras. Por sua vez, a alegria local (escolas, cidades, regiões, países) está associada a uma maior atividade empreendedora, o humor e sentimentos positivos, bem como a satisfação de vida geram efeitos benéficos, como melhor desempenho nas tarefas e produtividade, evolução na carreira e sucesso pessoal e maior propensão para assumir riscos. Percebemos então que é necessário desenvolver uma cultura de positividade, pelo que, sugerimos a implementação do novo quadro conceptual PROSPER (Positivity; Relationships; Outcomes; Strengths; Purpose; Engagement; Resilience) que tem o potencial de ser usado como uma ferramenta organizacional para a implementação dos sete principais componentes de bem-estar. Cientes de que o objetivo final é aumentar a intenção empreendedora dos estudantes, bem como o número efetivo de empreendedores, definimos como objetivos, promover o valor do empreendedorismo na criação de oportunidades e no desenvolvimento das competências dos estudantes (Engaging), fornecer aos estudantes oportunidades de aprendizagem empresarial (Empowering) e apoiar os estudantes na criação e no desenvolvimento de negócios (Equipping). Neste sentido, sugerimos diversas ações que materializam estes objetivos. Para finalizar, utilizamos um Lean Canvas com o intuito de concretizar a nossa proposta estratégica para ESEIG, que culmina com a criação do Empowering Lab ESEIG.
