- Why do SMEs implement open innovation? The case of PortugalPublication . Julião, Jorge; Ferreira, Inês; Gaspar, MarceloThe concept of open innovation is gaining popularity in both the world of engineering and management. However, despite this growing interest, most existing studies tend to focus mainly on large companies. Thus, the purpose of this paper is to explore the drivers of the implementation of the open innovation concept in SMEs. This study uses a survey carried out through an online questionnaire that was sent to some Portuguese SMEs. The results show that there is a high level of receptivity to implement open innovation. The findings also suggest the existence of a positive relationship between the application of open innovation and the level of satisfaction with the R&D unit’s performance. Overall, SMEs seem to be more motivated to apply open innovation to improve their innovation process and capacity than to reduce costs, share innovation risks, or improve reputation. Moreover, findings also demonstrate that the main drivers for the adoption of open innovation vary along with company size. For micro-enterprises, the main driver is to complement internal skills. Small enterprises look for the most effective way to develop new products and services whilst medium-sized enterprises are mainly driven to monitor market trends and improve their innovation process.
- Influence of planting location and growing season on the nutritional quality of lupinPublication . Osorio Pérez, Jazmín; Silva, Marta Nunes da; Santos, Carla Sancho dos; Rubiales, Diego; Barilli, Eleonora; Vasconcelos, Marta WiltonLupin is a highly nutritious legume crop, particularly in terms of protein, and certain accessions can accumulate up to 40% of this macronutrient. They are also rich sources of zinc (Zn), magnesium (Mg), iron (Fe), potassium (K) and calcium (Ca) along with vitamin A, B and E (Bryant et al., 2022). Nutritional quality has often been studied in germplam accessions, but environmental effects has often been neglected. This research seeks toquantify the nutrient accumulation variations that could result in lupins when altering the crop location and over two different growing seasons.

- Differential responses of Kabuli and Desi chickpeas (Cicer arietinum) to low water provision and their mineral profilingPublication . Medeiros, Janaína; Silva, Marta Nunes da; Santos, Carla S.; Vasconcelos, Marta W.Legume grains are of great importance for agriculture and the environment due to their ability to symbiotically fix atmospheric nitrogen and provide protein, minerals, vitamins, and other bioactive nutrients (Geraldo et al., 2022). Chickpea (Cicer arietinum) is one of the most consumed legumes worldwide and it has gained even more importance in recent decades. Production levels have increased, their incorporation as intercrops has been promoted, and they have been used in the formulation of novel food products (Saget et al., 2020). Nonetheless, the exploitation of traditional chickpea varieties, such as the Desi type (black coloured chickpea), has been overlooked, and the recovery of under-exploited traditional varieties could contribute to fostering biodiversity, and promoting environmental sustainability and diversifying diets. However, current knowledge on the nutritional profile of commercial and traditional chickpea varieties and their resilience degree to environmental stresses, such as water scarcity, is limited, thus being the focus of this work.
- Mineral profilling of a portuguese collection of common bean (phaseolus vulgaris l.) germplasmPublication . Moreira, Rosa; Vaz, Madalena; Barata, Ana Maria; Santos, Carla; Vasconcelos, Marta W.Common bean (Phaseolus vulgaris L.) is the most produced and consumed legume in Portugal. Recent data show an average national production of common bean of about 2397 tons, spread over about 3547 hectares of production area (FAOSTAT, 2017). As a rustic crop, beans are known to have great morphological variability and adapt to different environments and landraces and varieties vary morphologically and nutritionally. The nutritional composition of the grains can be conditioned by factors such as genotype, origin, environmental and cultivation conditions, influencing the quality of the seeds. Crop selection is generaly based on seed agronomic perfomance and the nutritional value has oftentimes been overlooked. The objective of this study was to evaluate 236 Portuguese common bean accessions from different Portuguese regions conserved in the National germplam bank for their mineral composition. Given the large diversity found in this local bean collection, understanding the intraspecific variability of mineral concentration may help in the identification of best performing accessions that can be adapted to different environmental conditions and improve thenutritional value of the seeds from farm to fork.
- Mineral profile and resilience to low water provision of white and black chickpea varieties (Cicer arietinum)Publication . Medeiros, Janaína; Silva, Marta Nunes da; Santos, Carla S.; Vasconcelos, Marta W.Legumes are of great importance for agriculture and the environment due to their ability to fix atmospheric nitrogen, providing important amounts of minerals, and vitamins, being are an excellent option for a balanced diet (Geraldo et al., 2022). Among the most consumed legumes worldwide, chickpeas (Cicer arietinum) have gained evidence in these past decades, through increased individual production, intercropping with other crops, and formulation of food products, thus improving the resilience of agroecosystems at lower environmental costs (Saget et al., 2020). However, the exploitation of traditional chickpea varieties, such as the black chickpea, has been overlooked, and the recovery of under-exploited traditional varieties could contribute to foster biodiversity, promote environmental sustainability and diversify diets. However, current knowledge on the nutritional profile of commercial and traditional chickpea varieties and their resilience to environmental stresses, such as water scarcity, is very limited, being the focus of this work.
- Digital entrepreneurship platforms: mapping the field and looking towards a holistic approachPublication . Fernandes, Cristina; Ferreira, João J.; Veiga, Pedro Mota; Kraus, Sascha; Dabić, MarinaEntrepreneurship is widely advocated as a driver of innovation and economic growth. Given today's technological and digital challenges, digital entrepreneurship in particular is a phenomenon on the rise, both through the digitization of existing businesses and the creation of digital enterprises. Debates on the relevance of digital entrepreneurship have been published in a range of journals that vary in terms of their purpose and readership. As such, scholarly contributions to this topic remain largely fragmented. To address this gap, this review aims to map academic literature on digital entrepreneurship in order to facilitate a better understanding of antecedents and future work. This study combines bibliometric approaches to examine literature on digital entrepreneurship platforms, forming a holistic picture of the field's different aspects and trends. The content and thematic analysis of 97 articles allows us to identify five approaches: i) Digital Entrepreneurship Success Factors, ii) Digital Entrepreneurial Ecosystems and Smart Cities, iii) Digital Entrepeneurial Models, iv) Sharing Entrepreneurial Platforms, and v) Digital Platforms about Entrepreneurship Co-creation. Our findings further highlight the various gaps in digital entrepreneurship literature and raise some research questions that warrant future academic research. Our holistic model holds several implications for the theory and practice of the different aspects of digital entrepreneurship.
- A communication study of young adults and online dependency during the COVID-19 pandemicPublication . Silveira, Patrícia; Morais, Ricardo; Petrella, SimonePeople use digital media and the Internet daily. The time that young people spend connected to digital devices will increase as technology advances, which could have severe health risks and behavioral dependence implications. In the context of the current pandemic, in which socializing, studying, and working is changing, this question has become particularly relevant. Therefore, we propose to investigate the perceptions of young university adults-understood as generation Z-regarding their digital media practices, particularly during the pandemic, and to study the consequences of a permanent connection to these formats on the development of an addiction to the Internet. Our quantitative method approach applied questionnaires to a sample of 407 young university adults studying in Portugal. Through this survey, we could target a specific user group, quantify their consumption, and measure their online experiences. The results point to an increase in dependence on the Internet during confinement. While it is true that carrying out academic work is one of the reasons for this growth, it is noteworthy that the respondents sought the online world in a significan way to pass the time and escape their routine. In addition, they confess to experiencing some consequences of excessive use, such as sleep disturbances and adverse emotional reactions-such as instabilities, depression, and nervousness-when not online. We conclude that the pandemic has intensified online dependence. However, above all that, it is necessary to look at the mental and general health consequences that this excessive use has brought, which may not be visible or manifested by the youth in the short term, and may come to have consequences in the long term.
