Abstract
The transistor is an electronic component that revolutionized the world of electronics, enabling the development and improvement of various systems and products in this area over the years. The paper transistor resulted from research conducted by a team coordinated by Elvira Fortunato. It is an ultra-small (nano) transistor, which is paper-based, a cheap and easily accessible material. This article intends, first, to determine the innovation model behind the paper transistor and, second, based on a survey of a sample of Portuguese firms in industries inclined to adopting the transistor, to understand its level of implementation and assess the determinants that may be influencing this process. A review of relevant literature and an interview with Elvira Fortunato, the key researcher, support the conclusion that the innovation model in question is the interactive one. In fact, since the project began, significant interaction took place between research institutions and industry, which continued throughout the development process. In the second phase of our work, a group of firms was surveyed, selected on the basis of the relevance of the technology on the activities they conduct. Only one firm from the five respondents said they knew of the paper transistor. The answers collected also indicated that there are three main determinants which explain why firms have failed to adopt this transistor: the expected profit, the existence of networks between firms and universities, and information. Thus, we conclude that there is a significant need for increased interaction between universities and firms, so as to promote a broader understanding of the stakeholders' needs, with the development of innovations in universities and research institutes based on adaptation to the business context.

Abstract
Entrepreneurial activities are seen as key drivers of innovation, job creation, and economic growth. Recent efforts are being pursued by several entities, including governments to promote entrepreneurial skills amongst the youngest. However, to design effective programs, policy makers have to uncover the determinants of entrepreneurship. To avoid that such efforts would be fruitless we argue that a multidisciplinary account of entrepreneurial intents among students is mandatory, circumventing past biased analysis towards business and engineering areas. Thus, in this paper we present the results of a survey to all final year university students of the largest Portuguese university. It encompasses a sample of 2430 students enrolled in 60 different courses of 14 schools/faculties. Results evidence that the average entrepreneurial intents reaches a reasonable (by international standards) figure of 27%, with students enrolled in non-traditionally entrepreneurial focused areas Humanities, Sports, Health and Sciences - and courses - Pharmacy, Veterinary, Law, Languages, History, History of the Arts and Archaeology, Sports, Biology and Chemistry, Dentistry - revealing higher entrepreneurial intents. Based on logit estimations, we further found that psychological factors, such as risk propensity, leadership profile, and creativeness, are the most important (positive) determinants of students' entrepreneurial intents. Contextual factors (e.g., family background and professional experience) failed to emerge as critical factors in explaining students' entrepreneurial intents - only business context emerged as important. Despite such results might at a first glance convey the idea that education policy for promoting entrepreneurship has limited application, we argue that it is not the case. What is required is different policy measures targeting students' attitudes and behaviors in both business and non business areas, avoiding the long-established mistake of confining entrepreneurial education related programs in business schools.

Abstract
The literature on FDI entry modes and corruption tends to convey the idea that corruption leads to a choice between low equity modes, i.e. joint ventures with local partners, and non-equity modes, namely exports and contracting, in order to avoid contact with corrupt state officials. Recently, some studies have argued that despite corruption, linguistic and historical ties between home and host countries lead MNCs to prefer high-equity modes. Focusing on a rather unexplored setting, the African countries, most specifically the Portuguese-speaking ones (PALOP - Paises Africanos de LIngua Oficial Portuguesa), which include countries where levels of corruption are very high (e.g., Guinea-Bissau and Angola), high (e. g., Mozambique, Sao Tome and Principe), and intermediate (e.g., Cape Verde), maintaining also close linguistic and historical ties with Portugal, we found that the FDI entry mode is associated with the less corrupt markets. Thus, our results do not support the recent contention that cultural and historical links are likely to perform a mediating role, by fostering foreign direct investment, in supporting African countries to overcome the dismal growth some have been facing in the last few decades. On the contrary, our findings highlight the pressing need for these countries to combat corruption if higher economic growth via FDI attraction is envisioned.

Abstract
The aim of this study is to test the multidimensional construct of the Entrepreneurial University (EU), and therefore to confirm whether EU factors make a positive contribution to regional competitiveness. Data were collected from ten Portuguese Public Universities (PPUs) through a self-administered questionnaire. First- and second-order confirmatory factor analyses (CFA) were performed through factor and multiple linear regression analyses. The main findings show that EU related factors-perceived and combined with actual regional metrics-especially entrepreneurial supporting measures, positively contributed to regional competitiveness. This study shows policy makers that universities are not merely cost centres but provide knowledge spillovers that can have a positive influence on regional competitiveness.

Abstract
Purpose This paper aims to investigate the evolution, roots and influence of the rural entrepreneurship literature.Design/methodology/approachUsing a bibliometric exercise, the analysis starts with investigation of studies on entrepreneurship and gathering all (772) articles on rural entrepreneurship (from 1981 to 2020) found in both Scopus and Web of Science up to 15 August 2020. Citation analysis of the references/citations of 755 articles are listed in the abstract database, generating a citation database involving 46,432 references/citations. This paper considers 635 (out of the 772) articles on rural entrepreneurship (i.e. articles cited in one or more studies), generating a database of 10,767 studies influenced by the rural entrepreneurship literature.Findings This study discovers that the relative importance of rural entrepreneurship within the entrepreneurship literature has increased in the last few years, but rural entrepreneurship remains a European concern; the most frequently addressed topics include growth and development, institutional frameworks and governance and rurality, with theory building being rather understudied. Most of the studies on rural entrepreneurship are empirical, involving mainly qualitative analyses and targeting high income countries; rural entrepreneurship is rooted in the fields of economics and entrepreneurship and is relatively self-referential.Originality/value This study provides a comprehensive and updated investigation of evolution of the rural entrepreneurship literature. The assessment of the literature's scientific roots of rural entrepreneurship had not yet been tackled before. To the best of the author's knowledge this study can be considered as the first effort for identifying the scientific influence of the rural entrepreneurship literature.

Abstract
The literature on the economics of location regarding creative activities is relatively scarce. Estimations, based on 369 newly created firms operating in creative industries in Portugal, which incorporate spatial effects of neighbouring regions in the location choices, yield the following results: (i) the concentration of creative and knowledge-based activities play an important role in location decisions of new creative establishments; (ii) creative firms tend to favour a diversified industrial tissue and related variety, in order to enjoy from inter-sectorial synergies; (iii) high education at a regional level has a highly significant, positive effect on location decisions, while lower educational levels of human capital negatively affect those decisions; (iv) tolerant/open environments attract creative activities; (v) creative firms tend to favour municipalities where the stock of knowledge and conditions for innovative activity are higher; (vi) municipality's attributes are more important in terms of firms' location decisions than the characteristics of nearby regions.
