How remote labs impact on course outcomes: various practices using VISIR

As technology is increasingly being seen as a facilitator to learning, open remote laboratories are increasingly available and in widespread use around the world. They provide some advantages over traditional hands-on labs or simulations. This paper presents the results of integrating the open remote laboratory VISIR into several courses, in various contexts and using various methodologies. These integrations, all related to higher education engineering, were designed by teachers with different perspectives to achieve a range of learning outcomes. The degree to which these VISIR-related outcomes were accomplished is discussed. The results reflect the levels of student engagement and learning and of teacher involvement. From the analysis, a connection between these two aspects was traced, although only related to the user profiles. VISIR is shown to be always of benefit for more motivated students, but this benefit can be maximized under particular conditions and characteristics.

The impact of national cultures on international marketing strategy and subsidiary performance of portuguese SME’s

The dynamic of the international business and its multidimensional nature requires the understanding of the complexities of different contexts dictated by cultural differences between countries. The purpose of this paper is to study, in depth howsmall and medium-sized companies develop their international marketing mix strategy in their overseas subsidiaries. We use the theoretical construct of Hofstede (1980, 1991) in the dimensions of Power Distance (PD), Uncertainty Avoidance (UA), Individualism (IND), Masculinity (MASC) and Long-Term Orientation (LTO) to assess the cross cultural differences between countries and the business practices to analyze the adaptation or standardization of the international marketing mix strategy of foreign Portuguese subsidiaries. Ourstudy uses an exploratoryand qualitative methodology. We conducted semi-structured interviews in order to achieve a good understanding ofinternational marketing mix strategy of four companies from different sectors. Our results show that the national cultural differences have great influence in the marketing strategy of the subsidiary. The business practices adjustments in the subsidiary company that proved to be necessary conditions for their performance are conducted by the products augmented offerings concerning the characteristics of the product, design and brand name in order to meet the requirements and specificities of the host country of the subsidiary.

Incorporating sustainability into a chemical company’s modus operandi

The intent of this dissertation is to review relevant existing management systems and chemical industry initiatives to identify synergies, overlaps and gaps with Sustainability best practices, to map the barriers to the incorporation of Sustainability and formulate recommendations to facilitate execution of Sustainability practices within existing management systems. A chemical industry Sustainability survey was conducted through APEQ, the Portuguese association of chemical companies, which constitutes the first baseline on the topic for this national industry association. The commonly used international standards and the Responsible Care® (RC) initiative were cross-referenced against the United Nations Global Compact Assessment Tool. Guidance on how to incorporate Sustainability into a company‘s modus operandi was collapsed into Sustainability Playbooks. The survey revealed that 73% of the APEQ member companies that participated in the survey have a Sustainability Plan. Both large and small/medium APEQ member companies see the market not willing to pay extra for ‗greener‘ products as one of the main barriers. APEQ large enterprise see complexity of implementation and low return on investment as the other most significant barriers while small/medium enterprise respond that the difficulty to predict customer sustainability needs is the other most significant barrier. Amongst many other insights from this survey reported to APEQ, Life Cycle Assessment practices were found to have a low level of implementation and were also considered of low importance, thus identifying a very important opportunity in Sustainability practices to be addressed by APEQ. Two hundred and seventy three assessment points from United Nations Global Compact Assessment Tool plus five additional items were cross-referenced with international standard requirements. With the authorization of the intellectual property owners, the United Nations Global Compact Assessment Tool was modified to introduce actionable recommendations for each gap identified by management standard. This tool was automated to output specific recommendations for 63 possible combinations after simply selecting from a list of commonly used management standards and the RC initiative. Finally this modified tool was introduced into Playbooks for Incorporation of Sustainability at two levels: a ―Get Started Playbook‖ for beginners or small/medium size enterprise and an ―Advanced Playbook‖ as a second advancement stage or for large enterprise.

Conceiving modern engineers within the framework of the sustainability action plan (PASUS) of ISEP: sustainability matters!

Engineering education practices have evolved not only due to the natural changes in the contents of the curricula and skills but also, and more recently, due to the requirements imposed by the Bologna revision process. In addition, industry is becoming more demanding, as society is becoming more and more aware of the global needs and consequences of industrial practices. Under this scope, higher education needs not only to follow but also to lead these trends. Therefore, the School of Engineering of the Polytechnic Institute of Porto (ISEP), a Global Reporting Initiative (GRI) training partner in Portugal, prepared and presented its Sustainability Action Plan (PASUS), with the main objective of creating a new kind of engineers, with Sustainable Development at the core of their graduation and MsC degrees. In this paper, the main strategies and activities of the referred plan along with the strategic approach, which guided its development and implementation, will be presented in detail. Additionally, a reflection about the above mentioned bridge between concept and application will be established and justified, in the framework of the action plan. Although in most of the situations, there was no prior discussion or specific request, many of the graduation and post-graduation programmes offered by ISEP already include courses that attend to PASUS philosophy. As a consequence, the number of Master thesis, Graduation projects and R&D projects that address sustainability problems has grown substantially, a proof that for ISEP community, sustainability really matters!

Supporting On-Line Distributed Monitoring and Debugging

Monitoring systems have traditionally been developed with rigid objectives and functionalities, and tied to specific languages, libraries and run-time environments. There is a need for more flexible monitoring systems which can be easily adapted to distinct requirements. On-line monitoring has been considered as increasingly important for observation and control of a distributed application. In this paper we discuss monitoring interfaces and architectures which support more extensible monitoring and control services. We describe our work on the development of a distributed monitoring infrastructure, and illustrate how it eases the implementation of a complex distributed debugging architecture. We also discuss several issues concerning support for tool interoperability and illustrate how the cooperation among multiple concurrent tools can ease the task of distributed debugging.

On the requirements of interpolating polynomials for path motion constraints

In the framework of multibody dynamics, the path motion constraint enforces that a body follows a predefined curve being its rotations with respect to the curve moving frame also prescribed. The kinematic constraint formulation requires the evaluation of the fourth derivative of the curve with respect to its arc length. Regardless of the fact that higher order polynomials lead to unwanted curve oscillations, at least a fifth order polynomials is required to formulate this constraint. From the point of view of geometric control lower order polynomials are preferred. This work shows that for multibody dynamic formulations with dependent coordinates the use of cubic polynomials is possible, being the dynamic response similar to that obtained with higher order polynomials. The stabilization of the equations of motion, always required to control the constraint violations during long analysis periods due to the inherent numerical errors of the integration process, is enough to correct the error introduced by using a lower order polynomial interpolation and thus forfeiting the analytical requirement for higher order polynomials.

Auditoria à gestão de resíduos industriais

A presente dissertação foi realizada em colaboração com o grupo empresarial Monteiro, Ribas, tendo como principal objectivo a realização de uma auditoria à gestão dos resíduos industriais produzidos pelas suas fábricas localizadas na Estrada da Circunvalação, no Porto. Para cumprir este objectivo, inicialmente foi efectuado um levantamento das obrigações legais relativas aos resíduos e foram procuradas práticas aconselhadas para a gestão interna. Para cada uma das fábricas, verificaram-se, quais os resíduos produzidos e analisaram-se os seus percursos, considerando as suas origens, os locais e modos de acondicionamento na origem, os modos de transporte interno, os locais e modos de armazenagem preliminar, e ainda, as quantidades produzidas, os transportadores, os operadores finais e as operações finais de gestão, sendo que estas quatro últimas informações são relativas ao ano 2013. De seguida procedeu-se à realização da auditoria nas diferentes unidades, verificando o cumprimento dos requisitos legais e das boas práticas em matéria de gestão de resíduos. As principais não conformidades detectadas, comuns às várias unidades fabris foram a inexistência de local/recipiente definido para acondicionamento de alguns resíduos, a falta ou insuficiente identificação de recipientes/zonas de acondicionamento, a inexistência de bacias de retenção para resíduos líquidos perigosos, o facto de no transporte interno apenas os resíduos perigosos serem cobertos e, os resíduos líquidos perigosos não serem transportados sobre bacias de retenção móveis nem com o material necessário para absorver derrames. Para cada resíduo e para cada unidade industrial foram propostas medidas correctivas e/ou de melhoria, quando aplicável. Relativamente à armazenagem preliminar, a principal inconformidade detectada foi o facto de todos os parques (quatro) possuírem resíduos perigosos no momento das auditorias, o que não é adequado. Foram propostas medidas correctivas e/ou de melhoria para cada parque. Como proposta global, tendo em conta factores económicos e de segurança, sugeriu-se que apenas o parque de resíduos perigosos possa armazenar este tipo de resíduos, pelo que os procedimentos de transporte interno devem ser melhorados, fazendo com que estes resíduos sejam transportados directamente para o parque de resíduos perigosos. Desta forma dois dos parques devem sofrer algumas remodelações, nomeadamente serem cobertos e fechados, ainda que não totalmente, e o parque de resíduos perigosos deve ser fechado, mantendo aberturas para ventilação, deve ser equipado com kit´s de contenção de derrames, fichas de segurança, procedimentos a realizar em caso de emergência, e ainda, devido ao facto do sistema de contenção de derrames ser pequeno face ao total de armazenamento, aconselha-se o uso de bacias de retenção para alguns dos recipientes de resíduos líquidos perigosos. Ao longo deste processo e em consequência da realização da auditoria, algumas situações consideradas não conformes foram sendo corrigidas. Também foram preparadas instruções de trabalho adequadas que serão posteriormente disponibilizadas. Foi ainda elaborada uma metodologia de avaliação de processos como base de trabalho para redução dos resíduos gerados. A etapa escolhida para a aplicação da mesma foi uma etapa auxiliar do processo produtivo da Monteiro, Ribas - Revestimentos, S.A - a limpeza de cubas com solventes, por forma a tentar minimizar os resíduos de solventes produzidos nesta operação. Uma vez que a fábrica já realiza a operação tendo em consideração medidas de prevenção e reutilização, a reciclagem é neste momento a única forma de tentar minimizar os resíduos de solventes. Foram então estudadas duas opções, nomeadamente a aquisição de um equipamento de regeneração de solventes e a contratação de uma operadora que proceda à regeneração dos resíduos de solventes e faça o retorno do solvente regenerado. A primeira opção poderá permitir uma redução de cerca de 95% na produção de resíduos de solventes e na aquisição de solvente puro, estimando-se uma poupança anual de cerca de **** €, com um período de recuperação do capital de cerca de 16 meses e a segunda pode conduzir a uma redução significativa na aquisição de solvente puro, cerca de 65%, e a uma poupança anual de cerca de **** €.

Changing representations and practices in school mathematics: the case of Modern Math in Portugal

The curricular movement known as Modern Mathematics aimed at the transformation of representations and practices in school mathematics. Its study provides us with ways of understanding how these changes came about. The purpose of this paper is to contribute to the understanding of the ways in which representations of school mathematics gradually were influenced by ideas from the Modern Mathematics movement, how these new ideas merged into local educational traditions, and how they were transformed into meaningful practice. This work is centred on the Portuguese context from the middle 1950s to the middle 1960s, and builds on Chervel’s notion of school culture and Gruzinski’s discussion of connected histories.
