    Do social and economic factors affect the technical efficiency in entrepreneurship activities? Evidence from European countries using a two-stage DEA model

    No full text
    This article aims is to address whether, and to what extent, socioeconomic conditions influence entrepreneurship-based activities in 18 European countries grouped into subregions (North, South, East and West) during the period 2008–2018. We conducted the empirical study under a two-stage DEA model. The results of scores of technical efficiency of the first stage of DEA show inefficiency in Northern Europe for Finland, Ireland and Sweden, while, Belgium, Germany, France and Luxembourg are also inefficient countries in Western Europe. Finally, Spain and Italy are inefficient in Southern European group of countries. In the second stage of DEA, through the parametric fractional regression model (FRM), which consolidated results of one-part and two-part models, the results show that the Expenditure on Social Protection produces positive (high magnitude coefficient) statistical significance on TEA of Eastern, Western and Southern EU countries, while generates a negative (high magnitude coefficient) statistical significance on TEA of Northern EU countries. Moreover, in the Eastern, Western and Southern EU countries, in contrast with Northern EU countries, presumably the dimensions of the social welfare (employment/unemployment protection and so on) are used to encourage individuals to invest in specific skills and/or new businesses. Furthermore, the results in this second stage of DEA helps gain a thorough perspective on how economic and social impacts result from TEA efficiency.info:eu-repo/semantics/publishedVersio

    Strategic decisions on bilateral bidding behavior: evidence from a wholesale electricity market

    No full text
    This article analyzes the strategic bilateral bidding behavior in the Spanish electricity wholesale market (OMEL). The collection of data includes information regarding weekly averages of spot prices, the quantity bid in the wholesale market, the quantities purchased in the wholesale market and sold in the open market, and the behavior of conduct parameters for the period from January 2002 to April 2007 for the four largest firms of the Spanish electricity market: Endesa, Iberdrola, Unión Fenosa and Hidrocantábrico. This article employs the New Empirical Industrial Organization approach. The empirical analysis was based on the autoregressive distributed lag approach to cointegration and on the Toda–Yamamoto Granger causality tests to validate the standard version of the theoretical formulation of the standard Cournot model, and its theoretical extension, to encompass the hypothesis of the presence of bid interdependence for electricity quantities sold and bought in the Spanish electricity wholesale market. The results of cointegration and causality analysis reinforce the empirical results of the extended Cournot model with the inclusion of the two main bidding variables that solved the optimization problem of profit maximization for each of the four firms analyzed.info:eu-repo/semantics/publishedVersio

    Características intrínsecas das substâncias perigosas

    No full text
    O que define a perigosidade de uma substância? Bioacumulação e persistência ambiental? Como estimar a toxicidade de determinada substância química? O que é a dose letal 50%? A identificação e gestão de substâncias perigosas é parte integrante da gestão e engenharia ambiental, química e da saúde ocupacional. As substâncias perigosas podem ser definidas pelas suas propriedades intrínsecas que possam apresentar riscos significativos para a saúde humana, segurança e para o meio ambiente. Estas propriedades incluem o estado físico da substância (sólido, líquido, gasoso), a sua reatividade química, toxicidade, inflamabilidade, corrosividade e capacidade de causar danos biológicos, físicos ou ecológicos

    Relatório Técnico Final - SHIFT-MARES (Science4Policy 2024 - S4P-24) Variações nos serviços de ecossistemas de áreas marinhas nacionais em cenários de alterações climáticas: Impactos no turismo costeiro

    Este documento sintetiza o enquadramento, o desenho metodológico, o plano de trabalhos e os principais resultados do projeto SHIFT-MARES, num formato orientado para suporte a decisão pública. O conteúdo foi preparado para leitura rápida por decisores e para uso técnico por equipas de planeamento e gestão. O relatório apresenta resultados de modelação ecológica e indicadores de potencial de fornecimento de serviços de ecossistema (SSP) associados ao turismo. O indicador SSP (EN - Service Supply Potential) descreve a capacidade ecológica de fornecimento de SEs, não a entrega efetiva observada, uma vez que não inclui procura turística, acessibilidade, preferências, ou restrições de governação.Science4Policy 2024 - S4P-24.

    Public policies, open innovation ecosystems and innovation performance: analysis of the impact of funding and regulations

    No full text
    Open innovation (OI) has been implemented to develop competitive advantages based on the management of innovation with external players. As such, it is expected that the generalized adoption of OI practices needs to be nurtured by governmental public policies in order to enhance OIbased ecosystems. The role of open innovation ecosystems is known by the importance of multiple synergies among players/stakeholders, which are expected to be supported by regulations and funding to consolidate firms’ innovation results. This paper analyzes the role of regulations and funding on firms’ innovation performance using the double-hurdle estimation procedure. The results show that, in the first tier, inbound knowledge flows positively affect performance, and, in the second tier, public funds further reinforce innovation performance and fiscal and security regulations. In contrast, as regulations are perceived as barriers, they fail to impact innovation performance. With this paper, we manage to shed light on the importance of public policy funds in the support of thriving OI-based ecosystems as enhancers of firms’ innovation performance.N/

    The effect of supply chain strategy on the relationship between innovation capabilities and business performance: a theoretical model

    No full text
    Although the relationship between supply chain (SC) and innovation has attracted attention from researchers in recent years, the relationship between innovation capabilities and SC strategies is a subject that has not yet been explored extensively. The main objective of this paper is to examine how SC strategies affect the relationship between innovation capabilities and business performance. The paper, characterised as a conceptual paper with the aim of contributing to theory building, is based on the concept of fit and on the principles of the contingency theory and the resource-based view. Further, a literature review and a theoretical discussion, a theoretical model and a set of research propositions are presented. The theoretical rationale shows the potential for improvement in performance through the relationship between innovation and SC and can be used to boost empirical research on the topic.This research is sponsored by FEDER funds through the program COMPETE – Programa Operacional Factores de Competitividade – and by national funds through FCT – Fundação para a Ciência e a Tecnologia –, under the project UIDB/00285/2020. This work is financed by National Funds through the Portuguese funding agency, FCT –Fundação para a Ciência e a Tecnologia, within project UIDB/50014/2020.info:eu-repo/semantics/publishedVersio

    Evolution of an adaptive serious games framework using the design science research methodology

    No full text
    Games with purposes beyond entertainment, the so-called serious games, have been useful tools in professional training, especially in engaging participants. However, their evaluation and, also, their adaptable characteristics to different scenarios, audiences and contexts remain challenges. This paper examines the application of serious games in professional training, their results and adaptable ways to achieve certain goals. Using the Design Science Research (DSR) methodology, a framework was built to develop and evaluate serious games to improve user experience, learning outcomes, knowledge transfer to work situations, and the application of the skills practised in the game in real professional settings. At this stage, the investigation presents a framework regarding the triangulation of data collected from a systematic literature review, focus groups and interviews. Following the DSR methodology, the next steps of this investigation, listed at the end of the paper, are the demonstration of the framework in serious game development and the evaluation and validation of this artefact.N/
