- Cape Verde: Islands of Vulnerability or Resilience? A Transition from a MIRAB Model into a TOURAB One?Publication . Sarmento, Eduardo Moraes; Silva, Ana Lorga daSmall island developing states (SIDSs) traditionally face a set of challenges like the weak and highly fragile economic configuration, environmental issues, and a traditional dependence on a few economic activities forcing them to open the economy to the exterior. Therefore, their development model, like in Cape Verde, depends on migration, remittances, dependence on aid, tourism, and state employment. The current research offers an insight into the nature of Cape Verde’s economy as a SIDS economy and the degree to which the country has been relying on tourism receipts, external remittances from migrations, aid programs, and government services. Understanding Cape Verde’s development model is important to clarify the challenges the country faces and its development needs to gather a long-term resilience and to understand if it is changing from a MIRAB (Migrations, Remittances, Aid, and Bureaucracy) model into another one.
- 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.
- Impact of tourism on Portugal’s regional developmentPublication . Rosário, Cátia; Silva, Ana Lorga da; Costa, António AugustoIt is widely recognized that tourism is an essential factor in the economic development of the regions. However, the different socio-demographic characteristics of each region can contribute to attracting or not tourists and tourist investment. In this chapter, the regional characteristics that contribute to the attraction of tourism are analyzed and carried out through linear regression models. Likewise, the authors analyze the impact of tourism on the development of regions, in terms of unemployment and wealth creation. The authors also try to understand the degree of dependence of the regions on foreign tourism, given that the tourism sector was severely affected by the beginning of the pandemic. This analysis is made in Portugal, by NUTS II, comparing the different regions of the country.
