Purpose The purpose of this paper is to involve the differences in the entrepreneurial intentions of student at higher education institutions (HEIs) in the Portuguese regions (mainland and insular). Design/methodology/approach Applying a sample of 594 valid responses, the authors analyzed the data according to linear regression models. Findings The results convey how HEI students generally do not intend to become entrepreneurs in both the mainland and the insular regions. Although HEI students broadly do not aim to launch their own businesses, the results show that students in mainland regions feel they have the skills to start a business and drive it to success. In insular regions, students feel encouraged by their friends and family to set up their own business. When comparing insular and mainland regions, the results demonstrate how in insular regions, there is a greater probability that HEI students become entrepreneurs than in the mainland regions. Furthermore, entrepreneurial intentions in the mainland regions develop in terms of “opportunities” while driven by necessity in the insular regions. Practical implications This furthermore makes recommendations to regional governments and to HEIs in order to enable better encouragement of entrepreneurship in academia. Originality/value This study is original and innovative due to its comparison of the entrepreneurial intentions prevailing in mainland and insular regions and may propose new highlights to the academic scientific literature.

The recent change in the regional development strategy of the European Union (EU) results in an important need to study the terms of change and their respective implications. This study seeks, through a bibliometric analysis, to ascertain the developments taking place in studies on research and innovation strategies for smart specialisation (RIS3) to identify shortcomings and opportunities for future research. This bibliometric review drew upon the Scopus database with the sample selected containing all the articles containing the keywords “Research and Innovation Strategies for Smart Specialisation” or “RIS3.” This correspondingly reports how some authors maintain that the path the EU should take involves imitative innovation. Meanwhile, others propose that each region should specialise in those industries that are already established there and thus avoid targeting any areas they do not already know/specialise in. Our findings detail six clusters in RIS3 research, which help in contextualising the literature review: (a) business discovery; (b) smart specialisation; (c) innovation; (d) specialisation; (e) regional policies; and (f) regional development. This study furthermore sets out perspectives for future lines of research and correspondingly seeks to convey a vast theoretical basis that may serve as the point of departure for future studies.

Olea europaea L. is one of the most economically important crops in the Mediterranean area, and known for having large genetic variability. In order to assess the genetic diversity, DNA from 41 olive cultivars, present in the protected denomination of origin (PDO) region of Trás-osMontes, was screened using inter simple sequence repeat (ISSR) and microsatellite (SSR) markers. Eleven ISSR primers amplified 135 reproducible bands of which 108 were polymorphic. The percentage of polymorphic bands detected by ISSR was 79%. The highest number of polymorphic bands was obtained by the use of primers UBC807 (15) and UBC809 (16). A total of 67 alleles were detected by six SSR primers, with an average of 11 alleles per primer. The number of alleles per locus ranged from five (ssrOeUaDCA05) to 15 (ssrOeUaDCA03). The observed heterozygosity ranged from 0.219 (ssrOeUaDCA05) to 0.900 (ssrOeUaDCA04), while the expected heterozygosity varied between 0.426 (ssrOeUaDCA05) and 0.887 (ssrOeUaDCA03). The polymorphism information content (PIC) values ranged from 0.392 (ssrOeUaDCA05) to 0.863 (ssrOeUaDCA03). The collection of primers selected gave a reasonable number of amplification products for the genetic diversity analysis. Based on the results, the genetic diversity among 41 olive cultivars is discussed. This study reveals the great importance of guaranteeing the differentiation of olive cultivars and their application for certification purposes.

Nonprofit sector integrates an important part of the economy, which serves as a critical factor for social change. Social innovation and social entrepreneurship are of paramount importance for the nonprofit sector aiming to solve social needs. The purpose of this paper is, through bibliometric mapping techniques, based on 2695 documents, to understand thematic evolution of social innovation and social entrepreneurship. The main conclusion is that, from the analysis, we can see that the scientific production in this field of knowledge has intensified in recent years, but the centrality and the search density undergo major changes. New paths for future research are outlined.

Olive oil composition has been investigated using chemical approaches, since the composition has a direct impact on its quality and safety and it may be used for certification purposes. In this paper, eleven monovarietal and twelve commercial Portuguese olive oils were analyzed to determine spectrophotometrically their total polyphenol content, ortho‐diphenols and antioxidant activity. The phenolic profiles of these olive oils were also studied by high performance liquid chromatography. The lowest phenolic content and antioxidant activity were observed for monovarietal olive oils, however, among these group, ‘Cobrançosa’ and ‘Redondil’ cultivars showed the highest values of these two chemical parameters. In commercial olive oils, the concentration of polyphenols, determined according to the Folin–Ciocalteu method, and the antioxidant activity (ABTS method) ranged from 97.37 ± 1.10 to 219.7 ± 1.50 mg GAE/kg of oil and from 387.2 ± 20.00 to 997.5 ± 30.90 µmol Trolox/kg, respectively. The study of the phenolic profile demonstrated that the highest concentrations of the most abundant compounds in olive oil (tyrosol, hydroxytyrosol and oleuropein) are present in commercial olive oils. The correlation coefficient between total phenolics and antioxidant activity was statistically significant (r = 0.95, p < 0.0001). The same was observed for ortho‐diphenol content and antioxidant capacity (r = 0.94, p < 0.0001).
