Determinant factors of turnover versus permanence of portuguese repatriates: an exploratory study

The study seeks to identify the determinant factors of the repatriate’s decision to remain or leave the company after repatriation, in a convenience sample of 40 Portuguese returnees working in companies based in Portugal. The main results were as follows: (1) there are seven factor categories: (a) salaries and benefits; (b) possibility of promotion, development, professional development; (c) organizational support (during and after the international mission) recognition of work; (d) economic and social atmosphere of the company, (e) good relationship with leadership; (f) convenience and/or personal / family well-being and; (g) external alternatives; (2) the main factors leading to permanence are (a) possibility of promotion, development and professional development and; (b) the existence of personal and family well-being / convenience; (3) the main factors leading to abandonment are (a) lack of organizational support and recognition of work performed; (b) lack of possibility of promotion, development and professional development and; (c) lack of personal / family well-being / convenience. Globally, the study suggests that the factors leading to permanence are very similar to those that lead to abandonment, although in reverse.

Natural Gas location design and operation

A major determinant of the level of effective natural gas supply is the ease to feed customers, minimizing system total costs. The aim of this work is the study of the right number of Gas Supply Units – GSUs - and their optimal location in a gas network. This paper suggests a GSU location heuristic, based on Lagrangean relaxation techniques. The heuristic is tested on the Iberian natural gas network, a system modelized with 65 demand nodes, linked by physical and virtual pipelines. Lagrangean heuristic results along with the allocation of loads to gas sources are presented, using a 2015 forecast gas demand scenario.

Influence of entrepreneurial orientation in export performance

This study aims at investigating the influence that entrepreneurial orientation has on export performance of Portuguese footwear small and mediumenterprises (SMEs). Therefore, a quantitative methodological approach was used, conducting a descriptive, exploratory and transversal empirical study, having applied a questionnaire to a sample of Portuguese companies exporting footwear. The research results suggest that entrepreneurial orientation enhances export performance in the analysed SMEs, particularly innovation and proactiveness, through the amount of funds invested, human resources dedicated to this activity, number of new products or services introduced in the market and frequent change in product lines or services and materialization of a long-term perspective, which is accompanied by innovative activities or new businesses. Therefore, the findings sustain the necessity to invest in entrepreneurial orientation as a strategic determinant, which contributes to the growth of small firms in foreignmarkets. Finally, the main limitation of this study is related to the sample size, since it was difficult to find companies willing to collaborate with this kind of research.

Initial dilemmas in IST research: design science and design research, a clarification of concepts

The inter-disciplinarity of information systems, applied discipline and activity of design, and the study from different paradigms perspectives explains the diversity of problems addressed. The context is broad and includes important issues beyond technology, as the application, use, effectiveness, efficiency and their organizational and social impacts. In design science, the research interest is in contributing to the improvement of the processes of the design activity itself. The relevance of research in design science is associated with the result obtained for the improvement of living conditions in organizational, inter-organizational and Society contexts. In the research whose results are artifacts, the adoption of design research as a process of research is crucial to ensure discipline, rigor and transparency. Based on a literature review, this paper clarifies the terms of design science and design research. This is the main motivation for presenting this paper, determinant for the phase in research in technologies and information systems which are the three research projects presented. As a result the three projects are discussed in relation to the concepts of design science and design research.

A internacionalização do setor bancário português

O processo de globalização, na esfera dos mercados financeiros, exigiu às instituições bancárias opções de investimento estratégico na plataforma internacional. O movimento de implantação dos bancos portugueses no estrangeiro acompanhou esse processo, permitindo a oferta de serviços bancários de captação e financiamento nos principais mercados de destino das exportações e emigração. A presente dissertação tem como objetivo o estudo do processo de internacionalização do setor bancário português centrado na seguinte questão geral de investigação: “Quais os fatores determinantes das variáveis que caraterizam a evolução do setor bancário português no exterior?” O desenvolvimento desta questão é conduzido através da construção de um modelo explicativo dos impactos de um conjunto de determinantes, selecionados a partir da revisão de literatura, sobre os indicadores que traduzem a dinâmica do negócio bancário no exterior. Neste contexto, pretendeu-se obter evidência empírica desses efeitos através de uma metodologia que consiste na estimação de modelos de dados em painel, utilizando uma amostra de seis bancos com relevância ao nível de investimento no mercado externo relativos ao período compreendido entre 2004 e 2014. Os resultados empíricos sugerem a existência de relações estatisticamente significativas entre as variáveis consideradas nos modelos. Foram encontrados indícios que associam consistentemente as variáveis emigração, Investimento Direto Estrangeiro, Produto Interno Bruto em Portugal e nos países de acolhimento, ativo bancário e inflação, com a evolução da atividade bancária no exterior. Adicionalmente, os resultados revelam que o desemprego e o rácio do crédito em relação ao ativo são estatisticamente significativos na sua influência sobre o indicador da rendibilidade dos bancos. Conclui-se que a significância dos fatores selecionados permite explicar o comportamento dos indicadores de negócio no exterior para os bancos estudados e, consequentemente, a validade do modelo de análise proposto. No entanto, não se exclui que outros elementos explicativos não ponderados no estudo tenham igualmente preponderância explicativa no processo de internacionalização do setor bancário.
