- Analyzing Pilot Projects of Creative Tourism in an Ultra-Peripheral Region : Which guidelines can be extracted for sustainable regional development?Publication . Santos, Carlos; Couto, Gualter; Albergaria, Isabel Soares de; Silva, Leonor Sampaio da; Medeiros, Pilar Damião; Simas, Rosa Neves; Castanho, Rui AlexandreSeveral authors have shown that some tourism typologies - i.e., rural tourism, nature-based tourism, or creative tourism - have a more predominant role in attaining regional sustainability. In this regard, this paper explores the impacts of five pilot projects of creative tourism on the sustainable development of the insular Autonomous Region of the Azores. Through direct exploratory tools, such as interviews and site analyses, the present study enabled us to provide greater insight into creative tourism projects and their relevance to the development of an ultra-peripheral island region. As part of the CREATOUR AZORES Project, this study is based on five creative tourism pilot projects operating in the Azores, Portugal. As such, it is recommended that the regional government, local authorities, and other relevant actors and players in this region actively support and create strategies to strengthen these projects (and similar initiatives) once they not only contribute to regional development and destination promotion but also promote much-desired sustainable development - once these kinds of tourism, in theory, and practice, counteract the dire effects of mass tourism.
- Territorial standards for innovation : analysis for the regions of PortugalPublication . Natário, Maria Manuela; Braga, Ascenção M. M.; Couto, João Pedro Almeida; Tiago, Maria TeresaCompetitiveness among regions and innovation dynamics are intimately related and depend on a solid and effective innovation system. This study aims to measure innovativeness in different Portuguese regions and to evaluate the nature of the innovation process and the relationship between innovativeness and its region of origin. To characterize the territorial innovation processes and to identify innovation patterns by regions, it analyzes their main distinctive factors, based on the Community Innovation Survey results for each region. Thus, it compares the Portuguese regions by verifying the existence of subjacent clusters and finding out the characteristics that distinguish the different groups of regions. The results point to the existence of four groups of regions, and the factors identified are related to the innovation process, namely objectives of innovation, sources of innovation, collaborative networks, triple helix performance, and obstacles to innovation.
- Statistical Analysis of the Leadership Perceptions in a Public Administration OfficePublication . Sousa, Áurea; Batista, Maria da Graça Câmara; Arruda, Ana C.The main purpose of this paper is to identify and characterize the leadership features in a public administration office of the Azores (Autonomous Region of the Azores), in orders to verify the existence or not of a positive leadership based on the employees’ perceptions. The main conclusions are attained using data gathered via a previously tested and validated questionnaire. Overall, we conclude that subordinates don’t consider that their leaders show behaviors that they can associate with a totally positive and effective leadership although they are pleased with the fact that they are not extremely controllers and that they seek to do what the majority of the subordinates wants.
- Entrepreneurship Promotion in Higher Education InstitutionsPublication . Sousa, Áurea; Couto, Gualter; Branco, Nélia Cavaco; Silva, Osvaldo; Bacelar-Nicolau, HelenaThe importance of entrepreneurship promotion has increased significantly in today's society, especially during periods of crises. This work is based on the responses obtained through a survey conducted on a sample of 305 undergraduates of the University of the Azores, enrolled in different science programs. The aim is to deepen the knowledge of the entrepreneurial propensity of higher education students in the Azores, and in that way the university can stimulate their interest in creating businesses. The main results obtained, using exploratory data analysis (from the univariate to the multivariate), are presented and discussed.
- Silence in organizations and psychological safety : a literature reviewPublication . Pacheco, Daniel Costa; Moniz, Ana Isabel Arruda; Caldeira, Suzana NunesIn the business world, employees can contribute with information, ideas, concerns, opinions and proposals to their managers in respect of: (1) the way work could be performed, (2) what should / should not be done in the workplace, (3) how a particular decision can be implemented, and (4) how an organizational policy should be formed and executed (Rego, 2013). However, due to a diverse set of factors, employees often choose to remain silent in the workplace. One of these factors is psychological safety, which describes employees’ perceptions of the consequences of taking interpersonal risks in the workplace (Edmondson, 2014). The following paper is essentially a literature review and its aim is to, firstly, make a brief approach to factors reported in the literature that may affect employee voice and silence, followed up by an explanation of the types of silence that can be engaged by employees. Besides that, the authors will also make an approach to physical and psychological safety. Lastly, it will be reported some links, mentioned in the literature, between employee silence and psychological safety.
- Adam Smith on power and maritime tradePublication . Martins, Nuno O.Adam Smith's An Inquiry into the Nature and Causes of the Wealth of Nations is often interpreted as an explanation of the self-regulating nature of the market system, where an "invisible hand" leads to a harmonious coordination of different economic agents' pursuit of self-interest, so that economic development is brought about naturally through the division of labor. However, a closer reading of Smith's contribution shows that he saw the expansion of the market as a process typically driven by military and political power. For Smith, cases of a natural and spontaneous growth of industry occur only due to exceptional circumstances.
- Sraffa on Fixed Capital, Money and the Phases of CapitalismPublication . Martins, Nuno O.In this paper I address some elements in Piero Sraffa's thinking that are connected to his conceptualization of the phases of capitalism. Sraffa describes various stages of capitalism using similar categories to the ones employed in the model of the economy provided in Production of Commodities. This is done by distinguishing the role of population, land and (circulating, intermediate and fixed) capital in each stage. Sraffa changed his conceptualization of fixed capital over the years, until he reached its final formulation. The conceptualizations of fixed capital that Sraffa discusses, together with his remarks on money which are made through an analogy with circulating and fixed capital, provide some elements that shed light on Sraffa's view of the dynamics of capitalism.
- Numerical Uncertainty and Its ImplicationsPublication . Rodrigues, António F.; Martins, Nuno O.A scrutiny of the contributions of key mathematicians and scientists shows that there has been much controversy (throughout the development of mathematics and science) concerning the use of mathematics and the nature of mathematics too. In this work, we try to show that arithmetical operations of approximation lead to the existence of a numerical uncertainty, which is quantic, path dependent and also dependent on the number system used, with mathematical and physical implications. When we explore the algebraic equations for the fine structure constant, the conditions exposed in this work generate paradoxical physical conditions, where the solution to the paradox may be in the fact that the fine-structure constant is calculated through different ways in order to ob-tain the same value, but there is no relationship between the fundamental physical processes which underlie the calculations, since we are merely dealing with algebraic relations, despite the expressions having the same physi-cal dimensions.
- An analysis of Internet Banking in Portugal: the antecedents of mobile banking adoptionPublication . Couto, João Pedro Almeida; Tiago, Maria Teresa Borges; Tiago, Flávio BorgesIn recent years, mobile operations have gained wide popularity among mainstream users, and banks tend to follow this trend. But are bank customers ready to move forward? Mobile banking appears to be a natural extension of Internet banking, . Thus, to predict consumer decisions to adopt mobile banking, it’s useful to understand the pattern of adoption of Internet banking (IB). This investigation seeks contribute to an expansion of the knowledge regarding this matter by researching Portuguese consumers’ patterns and behaviors concerning the acceptance and use intention of IB as a foundation for establishing growth strategies of mobile banking. For data collection, we used an online “snowball” process. The statistical treatment used included a factor analysis in order to allow examination of the interrelationships between the original variables. The analysis was made possible by developing a set of factors that expresses the common traits between them. The results revealed that the majority of respondents did not identify problems with the use of and interaction with the IB service. The study generated some interesting findings. First, the data generally supports the conceptual framework presented. However, some points need to be made: (i) trust and convenience, from all the elements referenced in the literature as relevant from the client’ perspective, continue to be a very important elements; (ii) the results did not support the paradigm that the characteristics of individuals affect their behavior as consumers, (iii) individual technological characteristics affect consumer adoption of IB service; (iv) consumer perceptions about the IB service affect their use, as reveal by the existence of three types of customers that show different practices and perceptions of IB; and (v) intention to use IB is dependent upon attitudes and subjective norms regarding the use of IB.
- Determinants of Length of Stay: A Parametric Survival AnalysisPublication . Moniz, Ana Isabel Arruda; Menezes, António Gomes deLength of stay is one of the most important decisions made by tourists as it conditions their overall expenditure and stress caused on local resources. This article estimates survival analysis models to learn the determinants of length of stay as survival analysis naturally lends itself to study the time elapsed between arrival and departure. It is found that sociodemographic profiles, such as nationality and gender, and trip attributes, such as repeat behavior, travel motive, and type of flight, are important determinants of length of stay. This article's results are important to design marketing strategies that effectively influence length of stay.
