- Covid-19 in Portugal - Economical consequences (an approach)Publication . Silva, A. L.This work intends to show how the pandemic SARS-CoV-2, responsible for the disease Covid-19, has affected all the world in several domains, also, differently from country to country. In particular, the way it has affected the Portuguese life, mainly concerning the country’s Economy. It also shows the evolution of the transmissibility rate, the numbers of infected cases and deaths as well as the vaccination plan in Portugal, which was a case of success due the implementation of a Task Force with that focus. Knowing that different factors are contained in Economic concept, such as health, GDP, inflation, employment (most of it could be affected by Lockdown measures), tourism flow among others. An approach related to the evolution of the disease in Portugal will be presented in this article.
- Perceção das Comunidades Locais Sobre Práticas Portuárias Sustentáveis.Publication . Caldeirinha, V.; Batista, M.; Felício, J.; Dooms, M.A percepção positiva do cluster portuário pelas comunidades locais é uma vantagem competitiva e facilita a licença social de operação e expansão do porto. Pretendemos compreender as práticas econômicas, sociais e ambientais dos gestores portuários que influenciam a percepção das comunidades locais e asseguram o desenvolvimento sustentável do cluster portuário. Definimos as práticas portuárias sustentáveis, medimos o seu impacto na percepção das comunidades locais e verificamos a influência moderadora das características da região e do cluster portuário. Utiliza-se o inquérito enviado aos stakeholders portuários e cidadãos portugueses. Uma amostra de 262 respostas suporta a metodologia com base no modelo de equações estruturais (SEM). Os resultados indicam a importância das práticas portuárias de controle do impacto do porto na região, comunicação do porto com a região, participação da região na gestão do porto e investimento portuário no desenvolvimento da região na influência da percepção das comunidades locais.
- Impact Of Human Capital On The Portuguese Economy Mediated By Intellectual PropertyPublication . Rosário, Cátia; Costa, António Augusto; Silva, Ana LorgaHuman capital and innovation are essential for the growth and development of nations. Human capital is an essential factor of production, being a positive externality that affects the economy in many ways and one of them is through its impact on innovation. The study presented refers to Portugal, between 2000 and 2015, with the main objective of analyzing the influence of human capital on the Portuguese economy through the results of innovation. Through the use of structural equation models, it was possible to establish a causal relationship between the following dimensions: • Human Capital, which is the result of a latent factor, considered as the cause of the variables observed with regard to the number of graduates in different areas of education. • Economic Growth, where the Gross Domestic Product was used as a measure. • Innovation results, which were measured through intellectual property, more specifically, through the registration of patents, brands and designs. In the model obtained, the results of innovation were used as moderating variables, allowing the analysis of the indirect impact of human capital on economic growth. This way, it is possible to conclude about the relationship between the mentioned variables, highlighting the importance of economic measures taken in terms of education, science and technology, contributing to the promotion of innovation in Portugal.
- Construction of Social Sustainability in Milk Production Systems in Central MexicoPublication . Ruiz-Torres, M. E.; Lorga da Silva, A.; Arriaga-Jordán, C. M.; Martínez-Castañeda, F. E.Objective: To build mathematical models to evaluate the social sustainability of small-scale milk production systems. Design/Methodology/Approach: Thirty small-scale cowsheds were analyzed. Two models were built using multivariate regression, estimated with ordinary least squares and considering the factors that producers perceive as important for social sustainability. Results: The first model (ER) included tangible variables and the second intangible variables (SR). Both models explained more than 80% of the variables associated with social sustainability. Study Limitations/Implications: The results represent an effort to link the statistical analysis with qualitative data that is difficult to quantify. Conclusions: The ER and SR models represent a proposal for counting immaterial indicators so they can be incorporated into the sustainability analysis. Both models could be a methodological proposal to connect statistical data with purely qualitative data such as perception.
- The complexity paradigm Towards a model for the analysis of social systems and problemsPublication . Parreira, Artur; Silva, Ana Lorga daThe article proposes the complexity paradigm as an innovative reasoning for analyzing problems in behavioral sciences. It begins to explain the contributions of the major authors of the complex reasoning paradigm: Gödel, Prigogine and Morin. They offer the basis to a model of analysis and assessment of complex systems and problems (ACSIP Model). The four postulates of the Model are explained, emphasizing the principal hypothesis of the Model – the level of cognitive operations is the most important factor of complexity of a system; then to understand it, the cognitive level of analysis must be at minimum equal to that of the system or the problem under analysis. In the second part the article, an illustrative application of the ACSIP Model is applied to the analysis of the SDG 9 from the UN 20/30 agenda, showing the analysis of a complex problem, guided by the complexity reasoning model. Following that, an empirical research is presented, to verify the hypothesis underlying the fourth postulate of the model. The results confirm the hypothesis: the use of information by a group is inversely proportional to the use of power (authority). These results allow us to conclude that the complex reasoning paradigm is a promising tool to obtain synergic results in the scientific analysis and resolution of concrete social problems and to face the complex challenges brought by artificial intelligence systems.
- Assessing the effectiveness of performance indicators in health organizations and professionalsPublication . Ferreira, Alexandre; Dias, ÁlvaroSeveral questions have been raised regarding the credibility, and consequent real value, of the assessment of professional performance as a management tool, considering that there are reports of situations in which the professionals are being evaluated based on objectives to be accomplished rather on the excellence of the performance of their task. As such, this study aims to analyse the introduction of metrics for evaluating the performance of health professionals’ performance indicators, and to identify the changes resulting from the introduction of performance indicators in the evaluation of physicians. Results reveal that physicians feel conditioned in the exercise of their professional activity by the need to comply with established performance indicators. Furthermore, it was also found that the cost reduction in primary healthcare may be insignificant when compared to the increase in secondary healthcare costs
- Designing and planning the downstream oil supply chain under uncertainty using a fuzzy programming approachPublication . Lima, C.; Relvas, S.; Barbosa-Póvoa, A.P.This paper addresses the strategic and tactical planning of a downstream oil supply chain (DOSC) subject to different sources of uncertainty. This problem is formulated as a mixed-integer linear programming (MILP) model, whereas uncertainty is tackled using chance constrained programming with fuzzy parameters. The MILP model aims at determining the network design and the products distribution plan in a cost-effective way. A real case study on the Brazilian oil industry is used to validate the model. The proposed model shows to be a valuable decision-support tool in order to aid the decision-making process in the strategic and tactical planning of real-life problems.
- Cruise destination characteristics and performance Application of a conceptual model to North Atlantic islands of MacaronesiaPublication . Luz, Luís Machado; Antunes, António Pais; Caldeirinha, Vítor; Caballé-Valls, Jordi; Garcia-Alonso, LorenaThe purpose of this study is to develop a conceptual model for both port and cruise destinations composed by site and situation-related factors as the main drivers with a direct influence on the performance of the cruise destination. A moderator variable was also included on the model, due to the different characteristics that cruise ports at distinct levels of development present. The conceptual model was then applied on the North Atlantic archipelagos of the Macaronesia region through a survey aimed at cruise specialists and stakeholders. The results of a structural equation model confirmed the concept model, which was subsequently validated through several interviews to senior officials of cruise line operators. Significant differences were observed between the more developed ports of the region and the less developed ports . For the more developed ports, there is a shared influence of both site- and situation-related factors, while in the less developed ports the main drivers are mostly restricted to site-related factors.
- Green Shipping Effect on Sustainable Economy and Environmental Performance.Publication . Felício, J. Augusto; Rodrigues, Ricardo; Caldeirinha, VitorThis paper focuses on green shipping and its’ influence on the sustainable economy and environmental performance. Based on the green shipping approach, this empirical study examines a survey sample of 193 responses from Portuguese and Spanish executive managers and uses exploratory factor analysis and structural equation model. The Green shipping approach supports the green theory. The results show the importance of green efficiency, green management, and pollution impact. The confirmation of the sizeable influence of green shipping on the sustainable economy and environmental performance constructs constitutes a major contribution to the literature. Green management and green efficiency contribute to controlling the impact of pollution with practical effects on economic sustainability. Another contribution arises from the fact that tax and financial incentives and environmental sustainability regulations indicate the relevance of the pollution impact and sustainable economy.
- O Uso da Tecnologia da Informação na Inovação dos Sistemas Logísticos PortuáriosPublication . Caldeirinha, Vítor; Nabais, João LemosAs características dos Port Community Systems (PCS) afetam como a colaboração entre os players pode ser estabelecida na comunidade portuária. A digitalização feita em terminais no âmbito dos PCS tem fomentado o desenvolvimento da colaboração horizontal na comunidade portuária. O acesso a dados e informações relevantes cria oportunidades para novos modelos de negócios para a comunidade portuária. Através da análise realizada neste estudo, concluímos que a implementação de uma Internet Física pode levar décadas, mas a mudança nos serviços prestados pelo PCS está configurando uma mudança de mentalidade de Cadeias de Abastecimento Isoladas para Cadeias de Abastecimento Abertas, promovendo a Internet Física.
