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.

Learning and Knowledge in the Context of Absorptive Capacity

Develop a new model of Absorptive Capacity taking into account two variables namely Learning and knowledge to explain how companies transform information into knowledge

Web 2.0 and its impact on knowledge and business organizations

Today, information overload and the lack of systems that enable locating employees with the right knowledge or skills are common challenges that large organisations face. This makes knowledge workers to re-invent the wheel and have problems to retrieve information from both internal and external resources. In addition, information is dynamically changing and ownership of data is moving from corporations to the individuals. However, there is a set of web based tools that may cause a major progress in the way people collaborate and share their knowledge. This article aims to analyse the impact of ���Web 2.0��� on organisational knowledge strategies. A comprehensive literature review was done to present the academic background followed by a review of current ���Web 2.0��� technologies and assessment of their strengths and weaknesses. As the framework of this study is oriented to business applications, the characteristics of the involved segments and tools were reviewed from an organisational point of view. Moreover, the ���Enterprise 2.0��� paradigm does not only imply tools but also changes the way people collaborate, the way the work is done (processes) and finally impacts on other technologies. Finally, gaps in the literature in this area are outlined.

Solid-state Marx based two-switch voltage modulator for the On-Line Isotope Mass Separator accelerator at the European Organization for Nuclear Research

A new circuit topology is proposed to replace the actual pulse transformer and thyratron based resonant modulator that supplies the 60 kV target potential for the ion acceleration of the On-Line Isotope Mass Separator accelerator, the stability of which is critical for the mass resolution downstream separator, at the European Organization for Nuclear Research. The improved modulator uses two solid-state switches working together, each one based on the Marx generator concept, operating as series and parallel switches, reducing the stress on the series stacked semiconductors, and also as auxiliary pulse generator in order to fulfill the target requirements. Preliminary results of a 10 kV prototype, using 1200 V insulated gate bipolar transistors and capacitors in the solid-state Marx circuits, ten stages each, with an electrical equivalent circuit of the target, are presented, demonstrating both the improved voltage stability and pulse flexibility potential wanted for this new modulator.

Agent Inferencing Meets the Semantic Web

We provide all agent; the capability to infer the relations (assertions) entailed by the rules that, describe the formal semantics of art RDFS knowledge-base. The proposed inferencing process formulates each semantic restriction as a rule implemented within a, SPARQL query statement. The process expands the original RDF graph into a fuller graph that. explicitly captures the rule's described semantics. The approach is currently being explored in order to support descriptions that follow the generic Semantic Web Rule Language. An experiment, using the Fire-Brigade domain, a small-scale knowledge-base, is adopted to illustrate the agent modeling method and the inferencing process.

Looking the organization's "backstages": political leadership in health organizations

Although leadership investigation has become for the last years an election topic with major relevance on organizational studies and accepting peacefully the general idea that organizations are freeland for politics, all these acceptances run against a kind of ���fear��� from the academy scholars on approaching the political leaderships��� singularities on organizations. Indeed, when we cross over both phenomena we verify that the absence and weaknesses towards the unique characteristics of political leadership on work scenarios are becoming sharped regarding to their predictors, their workers and their organizations, even if we left aside its moderator variables.

Sistema de apoio �� criminologia

Este trabalho consiste no desenvolvimento de um Sistema de Apoio �� Criminologia ��� SAC, onde se pretende ajudar os detectives/analistas na preven����o proactiva da criminalidade e na gest��o dos seus recursos materiais e humanos, bem como impulsionar estudos sobre a alta incid��ncia de determinados tipos de crime numa dada regi��o. Historicamente, a resolu����o de crimes tem sido uma prerrogativa da justi��a penal e dos seus especialistas e, com o aumento da utiliza����o de sistemas computacionais no sistema judicial para registar todos os dados que dizem respeito a ocorr��ncias de crimes, dados de suspeitos e v��timas, registo criminal de indiv��duos e outros dados que fluem dentro da organiza����o, cresce a necessidade de transformar estes dados em informa����o proveitosa no combate �� criminalidade. O SAC tira partido de t��cnicas de extrac����o de conhecimento de informa����o e aplica-as a um conjunto de dados de ocorr��ncias de crimes numa dada regi��o e espa��o temporal, bem como a um conjunto de vari��veis que influenciam a criminalidade, as quais foram estudadas e identificadas neste trabalho. Este trabalho �� constitu��do por um modelo de extrac����o de conhecimento de informa����o e por uma aplica����o que permite ao utilizador fornecer um conjunto de dados adequado, garantindo a m��xima efic��cia do modelo.

Inser����o profissional: os desafios nos primeiros anos de ensino

A problem��tica da inser����o profissional dos novos professores tem sido largamente estudada sob v��rias perspetivas das quais destacamos, as dificuldades enfrentadas no in��cio do seu desempenho como docentes (Alen y Sardi, 2009) Krichesky y Merodo (2009), o vinculo entre inser����o e identidade profissional (Martineau y Portelance, 2005), o desenvolvimento da compet��ncia ��tica nos novos professores (St. Vincent 2011) e as trajet��rias de emprego, entre outras.Os resultados destas pesquisas t��m revelado o tipo de problemas enfrentados pelos novos professores �� entrada na carreira docente e confirmado que nem todos os percursos se iniciam de modo tranquilo e sereno. �� esta a problem��tica que serve de base ao objeto de estudo desta disserta����o, pretendendo-se mais precisamente, centrar a nossa pesquisa no percurso profissional de seis professores diplomados pela Escola Superior de Educa����o de Lisboa h�� dois anos. O objetivo geral do estudo ��, assim, descrever e compreender o desenvolvimento profissional desses professores, identificar as dimens��es mais relevantes, os fatores que o condicionam e os contextos que o limitam ou facilitam. Tendo em conta o objeto de estudo identificaram-se as seguintes quest��es: 1) Quais as implica����es da forma����o inicial no desempenho da profiss��o? 2) Quais as principais dificuldades / problemas com que se defrontaram os novos professores na inser����o na profiss��o?; 3) Como atuam os professores principiantes?; O que mudam nas suas pr��ticas, o que perdura?; 4) Como se incrementa o sentimento de perten��a ao novo grupo profissional?; 5) Quais as particularidades dos contextos de trabalho em que estes professores se encontram integrados que se revelam facilitadoras e/ou constrangedoras da sua inser����o profissional? Para o efeito recorremos a uma metodologia qualitativa, e privilegi��mos como t��cnica de recolha de dados a entrevista semiestruturada. Para o tratamento dos dados sustent��mo-nos na an��lise de conte��do seguindo os passos recomendados para a an��lise de conte��do (Bardin, 2009). Os resultados do estudo permitiram identificar os constrangimentos experimentados por estes professores �� entrada da profiss��o, assim como os modos como os ultrapassaram. Destes, destacam-se dificuldades relacionadas com a falta de autonomia, com aspetos de natureza metodol��gica, ao n��vel da organiza����o e desenvolvimento curricular e de relacionamento com os elementos da dire����o das institui����es nos contextos de trabalho.Abstract The issue of employability of new teachers has been widely studied from various perspectives. Research has revealed the sort of problems faced by new teachers at the beginning of their career. It confirms that frequently it is not a peaceful and serene start. We highlight the following difficulties: the link between integration and professional identity (Alen y Sardi, 2009; Krichesky y Merodo, 2009), the development of ethical competence in new teachers (y Portelance Martineau, 2005), and the professional path (St. Vincent 2011). This is the hypothesis explored in this thesis. Specifically, we focus our research on the career of six graduate teachers by the Lisbon School of Education. The main objective is to describe and understand the professional development of these teachers. For that we identify the most relevant dimensions, the factors that constrain and contexts that limit or facilitate their development. A qualitative methodology was used throughout the study. Semi structured interviews were the main data collection process. Data treatment followed the recommended framework for content analysis (Bardin, 2009). The following research questions were put forward: 1) What are the impacts of base level of knowledge in the professional performance? 2) What are the main difficulties / problems that new teachers face? 3) How do novice teachers perform? What changes in their methods, what endures? 4) What increases the feeling of belonging to the new professional group? 5) What are the peculiarities of work contexts that act as facilitators and/or barriers to professional acceptance? The results allowed identifying the constraints experienced by teachers at the beginning of their careers, and the ways to surpass them. We highlight the difficulties related to: lack of autonomy; methodologies; curricular organization and development; and the relationship with the directors at their workplace.

Symbolic Knowledge Extraction from Trained Neural Networks Governed by Lukasiewicz Logics

This work describes a methodology to extract symbolic rules from trained neural networks. In our approach, patterns on the network are codified using formulas on a Lukasiewicz logic. For this we take advantage of the fact that every connective in this multi-valued logic can be evaluated by a neuron in an artificial network having, by activation function the identity truncated to zero and one. This fact simplifies symbolic rule extraction and allows the easy injection of formulas into a network architecture. We trained this type of neural network using a back-propagation algorithm based on Levenderg-Marquardt algorithm, where in each learning iteration, we restricted the knowledge dissemination in the network structure. This makes the descriptive power of produced neural networks similar to the descriptive power of Lukasiewicz logic language, minimizing the information loss on the translation between connectionist and symbolic structures. To avoid redundance on the generated network, the method simplifies them in a pruning phase, using the "Optimal Brain Surgeon" algorithm. We tested this method on the task of finding the formula used on the generation of a given truth table. For real data tests, we selected the Mushrooms data set, available on the UCI Machine Learning Repository.
