  1. Importance-satisfaction model for quality improvement: the case of higher education

    Silva, Fátima H.; Fernandes, Paula O.
    Students are the reason of being of Higher Education Institutions. Times have changed, so their future depends on their capacity to attract and retain students. In this context, it is crucial determining the importance that students place on the product or service attributes that drive their satisfaction with service providers is an essential part of a Higher Education Institutions resource allocation process. An uncomfortable issue is whether importance measures should come directly from students or be derived statistically and, if so, how. This study attempts to determine the key quality factors influencing student’s satisfaction in Higher School of Technology and...

  2. Is there a causal relation between construction activity and the Portuguese economy? An econometric empirical application

    Nunes, Alcina; Lopes, Jorge; Balsa, Carlos
    It has long been recognised that the role of the construction industry in a country’s national economy goes beyond its share in national output. Existing paradigms on the structural change of the construction industry as national economy develops over time have been evolving from an approach that stresses the role of construction investment (indeed physical capital) as an engine of economic growth to one where the pattern of the evolution of the industry should follow that of the general economy. Using time–series data drawn from the United Nations national accounts databases, this study applies an econometric methodology to assess the...

  3. Evaluation of dynamic participation in portuguese active employment programmes

    Nunes, Alcina
    Over the past decades, European labour market policies, like the Portuguese, offer not only a set of simultaneous active programmes, to the universe of unemployed registered individuals, but also the possibility of successive participation in different active programmes. Such dynamic participation patterns have as a consequence different average causal effects to participants. Aware of this reality, the present paper discusses how to overcome the limitations of the traditional labour market microeconometric evaluation literature, eminently static, to empirically estimate the impact of dynamic selection. In recent years it is possible to report several developments concerning the introduction of dynamic elements in...

  4. Using importance-performance analysis in evaluating institutions of higher education: a case study

    Silva, Fátima H.; Fernandes, Paula O.
    A large number of management quality models that are universally applied in the business environment, have been adapted and used in the education sector. The aim of this paper is to assess the quality attributes of higher education from different perspectives, namely from that of School of Technology and Management students, applying the Importance Performance Analysis. The results show that students are satisfied with their institution.

  5. Avaliação de fusões no grupo crédito agrícola

    Pires, Adérito; Ribeiro, Humberto
    O objectivo deste artigo é o de avaliar em que medida os processos de fusão dentro do grupo Crédito Agrícola (CA) são considerados proveitosos quer para a organização quer para os seus colaboradores. A forma de aferir essa avaliação foi efectuar um inquérito dirigido a todos os colaboradores questionando-os sobre a sua percepção do processo e as suas perspectivas para o futuro, em comparação com o que seria caso não tivesse ocorrido a fusão. Os resultados do inquérito podem ser considerados positivos quer ao nível da adesão verificada quer ao nível dos resultados. Sobre os mesmos podemos concluir que os...

  6. A semi-parametric survival analysis of business demography dynamics in Portugal

    Nunes, Alcina; Sarmento, Elsa
    We address the post-entry performance of new Portuguese firms by investigating the structural characteristics of the hazard and survival functions, using semi-parametric survival analysis. It is based on the application of the entrepreneurship definitions and methodology of the “Manual on Business Demography Statistics” (OECD/Eurostat, 2007) to the Quadros de Pessoal dataset. The main contribution of this work is the application of a recent internationally comparable methodology for entrepreneurship to provide a multidimensional overview of firm and survival dynamics over a period of eighteen years, while guaranteeing international comparability. By correcting heterogeneity with a different specification model, we obtain stronger magnitudes of the...

  7. Applying the artificial neural network methodology for forecasting the tourism time series

    Fernandes, Paula O.; Teixeira, João Paulo
    This paper aims to develop models and apply them to sensitivity studies in order to predict demand. It provides a deeper understanding of the tourism sector in Northern Portugal and contributes to already existing econometric studies by using the Artificial Neural Networks methodology. This work's focus is on the treatment, analysis, and modelling of time series representing “Monthly Guest Nights in Hotels” in Northern Portugal recorded between January 1987 and December 2005. The model used 4 neurons in the hidden layer with the logistic activation function and was trained using the Resilient Backpropagation algorithm. Each time series forecast depended on 12 preceding values. The analysis...
