The concept of Bioeconomy is associated with sustainable development changes both in production and consumption systems. For this reason, this research was carried out with the objective to describe the scientific production related to the different strategic groups’ perceptions about Bioeconomy and to group the existing literature into thematic clusters. Initially, in this bibliometric study, 67 articles were selected from the Scopus database based on the words “Bioeconomy” and “Perceptions”. Later, the VOSviewer software, version 1.6.18, was used to perform the bibliometric analysis. The results revealed the existence of four clusters. The first cluster included articles about Bioeconomy on the perspective of the timber strategic sector and of the different actors in the field of forestry action closest to the Bioeconomy field. The second cluster included articles related to the perception about Bioeconomy by Civil Society, in general, and higher education students, in particular, as well as their opinions on the importance of the forestry sector for the Bioeconomy. The third cluster comprised the articles that consider the Bioeconomy to be the innovative way to go to ensure the sustainability of the planet, therefore highlighting the importance of knowing the perceptions and raising awareness of all strategic groups to ensure the successful transition to the Bioeconomy. Finally, the fourth cluster included articles related to the consumer attitudes and behaviours regarding the acceptance of new biofood products resulting from the Circular Economy.

The expectation created around 5G is great. Major changes are fore seen, in very different areas, which will have a great impact on people’s daily lives. It is expected that smart cities will be more efficient, more sustainable and safer, with significant impacts on the people who inhabit them and also on the people who visit them. 5G technology is not being implemented in the world in a com prehensive and similar way, there are countries that already have a large coverage of this network and others that are still barely talking about this fifth-generation technology of mobile communications. Given that there is still a great unknown and uncertainty in relation to 5G, the question that this research work intends to address is to what extent this technology can initiate an intelligent era, which, in turn, provides a better quality of life for people, which each they are in greater numbers, living in cities. Thus, this work intends to cross these growing trends, with the new paradigm that is the implementation of 5G. For this, the Scopus database was used, where a search was carried out in the most recent scientific literature on these topics, since they are very current trends. The results are dis cussed in the light of the literature and future work is identified with a view to contributing to the enrichment of those who are dedicated to these recent themes but which are in great exponential growth. info:eu-repo/semantics/publishedVersion

When the discussion on sixth-generation (6G) mobile communication networks begins in Portugal, the implementation of 5G on the ground is taking its first steps. Portugal is one of the European Union (EU) countries that is most behind in the implementation of this technology, although the European Commission considers its implementation essential for the strategy of digitizing Europe. The question that this research work intends to address is to what extent this technology can start a smart era, which in turn, provides a better experience for tourists visiting Portugal. It is known that the tourism sector in Portugal is fundamental as an economic activity, as well as for generating more wealth and creating more jobs. Thus, this work aims to cross these growing trends in our country and in the world, with the new paradigm that the implementation of 5G in Portugal is. For this, using the Scopus database, a search was carried out in the most recent scientific literature on these topics, since they are very current trends. The results are discussed in the light of the literature and future work is identified with a view to enhancing tourism, smart tourism, and smart destinations, a set of measures that can boost these concepts will also be presented. info:eu-repo/semantics/publishedVersion

Despite being an emerging phenomenon, the literature on how ICT impact the adoption of sustainable agriculture has aroused growing interest on the part of farmers, scientific and business communities and policy makers. There fore, the main objective of this study was to investigate the state-of-the-art of ICT use in agriculture with an impact on the sustainability of the sector. In order to achieve this objective, a computer-assisted bibliographic search was performed in February, 2023. This search included all publications available in the Scopus database and was based on the words “Impact” OR “Contributions” AND “in formation” AND “Communication” AND “Technologies” AND “Sustainability” AND “Agriculture”. Subsequently, publications were selected taking into account the following criterion: empirical studies that demonstrate evidence of the impact or contribution of ICT to sustainable agriculture. For each publication, it was col lected information about authorship and publication date, place where the study was developed, type of study, methods, objectives and findings. All studies show positive contributions as a result of the use of ICT and artificial intelligence for the adoption of a sustainable agriculture with lower resources’ consumption, namely, improvement of soil quality, greater efficiency in the use of water and energy with the use of solar energy, greater efficiency in the application of nitrogen, minimiza tion of the use of inorganic fertilizers, reduction of food waste and improvement of food security, greater involvement of farmers with sustainability concerns and promotion of more sustainable consumption. info:eu-repo/semantics/publishedVersion

Smart Cities promote a great improvement in urban environments in terms of sustainability, leveraged by the use of technologies that allow the opti mization and monitoring of different systems, from waste management systems to public safety. There are several technologies that can play a key role in this process, highlighting augmented computing, augmented reality, virtual reality, artificial intelligence, and machine learning. In this context, smart cities collects and analyses, optimizing the various systems processes. There are many chal lenges that arise in order to have sustainable smart cities, challenges in terms of privacy and data security, but also in promoting inclusion and equity. It is impor tant to adopt an inclusive and holistic approach that involves all stakeholders and takes into account the specific needs and objectives of a city. With this in mind, the adoption of augmented computing technologies facilitates the creation of more livable and also more sustainable urban environments. The main objective of this work is to explore the area of augmented computing in the context of smart cities sustainability. info:eu-repo/semantics/publishedVersion

La castaña está profundamente arraigada en la economía portuguesa, en la gastronomía y en el patrimonio cultural. Por estas razones, este trabajo pretende comprender el comportamiento de los consumidores portugueses de castañas, sus preferencias, usos, hábitos de compra y percepciones sobre los beneficios del consumo de castañas. Para eso, se realizó un estudio transversal basado en una muestra de 320 individuos. Los consumidores encuestados compran un promedio de 6,5 kg/año. La mayoría compra castañas frescas y lo hace ocasionalmente, principalmente en supermercados e hipermercados, ferias o directamente al productor. Los consumidores prefieren comprar la castaña sin embalaje y los atributos más valorados son la percepción de la calidad, el tamaño y el precio. El distrito de residencia y los ingresos mensuales del hogar resultaron ser factores diferenciadores de la frecuencia de consumo de castañas. De hecho, se consumen castañas con mayor frecuencia en Oporto y otros distritos portugueses no productores de castañas, y en hogares con ingresos mensuales entre los 580 y 1740 euros y con más de 3480 euros. El tamaño, el estado de conservación de la cáscara, el origen y la percepción de calidad de los consumidores son factores determinantes de la compra de castañas frescas. Estos hallazgos revelan que, a fin de mejorar los datos de consumo de castaña, es necesario comunicar mejor las cualidades nutricionales y los posibles efectos beneficiosos para la salud del consumo de castañas e invertir en I+D de nuevos productos alimenticios, terapéuticos y cosméticos hechos con castañas. Chestnut is deeply rooted in the Portuguese economy, gastronomy and cultural heritage. For this reasons, this paper aims to understand the behavior of Portuguese chestnut consumers, their preferences, uses, buying habits and perceptions about the benefits of consuming chestnuts. For this, a cross-sectional study was carried out based on a sample of 320 individuals. The surveyed consumers buy, on average, 6.5 kg/year. Most consumers buy fresh chestnuts and do so occasionally, mainly in supermarkets and hypermarkets, fairs or directly from the producer. The consumers prefer to buy the chestnut without packaging and the most valued attributes are quality perceived by the consumer, size and price. The district of residence and the monthly household income revealed to be differentiating factors of the frequency of chestnut consumption. In fact, chestnuts are consumed more frequently in Oporto and other Portuguese non-producer districts of chestnut and in households with an income from 580 to 1740 euros and more than 3480 euros. The size, the shell conservation state, the origin and the quality perceived by consumers revealed to be determinant factors of the purchase of fresh chestnuts. These findings point out the need to better communicate the nutritional qualities and possible beneficial health effects of chestnut consumption and to invest in R&D of new chestnut-based food, therapeutic and cosmetic products.

Human resources are essential to respond to changes that occur inside and outside organizations. Literature states that when employees are satisfied, they feel more involved and committed to the organization and, as such, they often express their intention to remain in the organization. In this context, this research aimed to consolidate the existing research in the field of organizational commitment in higher education. Methodologically, this research was based, in a first stage, on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta- Analyses) statement and, in a second stage, on the bibliometric analysis. For this, the search was developed, in November 2021, in the Scopus database being selected 71 publications based on the combination of the terms "higher", "education", "institutions", "organizational", "commitment" and "satisfaction”. Then, this search was limited to the “Social Sciences” area (38 publications). Finally, abstracts and, when necessary, the entire text was selected in order to verify the relevance of publications for this research, considering the following criteria: study location, type of study, objectives, sample size and contributions, totalling 35 articles. The elaboration of the bibliometric analysis was done using the VOSviewer software, version 1.6.17 and the binary counting method. The minimum number of occurrences was set at five. Three thematic approaches that were related to each other were identified. The first included the terms “addition”, “communication”, “element”, “higher education sector”, “mediating role”, “model”, “organizational performance”, “problem” and “TQM” (Total Quality Management). This approach analyses the association between TQM and organizational performance, having as mediator elements of human orientation, namely, satisfaction with communication, commitment and organizational loyalty. The second approach included the terms “academic staff”, “consequence”, “effect”, “higher education institutions”, “impact”, “implications”, “influence”, “organizational culture”. In general, it analyses the influence, effects, consequences, impact and implications of organizational culture on organizational commitment and faculty satisfaction in higher education institutions. Finally, the third approach relates organizational commitment and job satisfaction with the turnover intention (leaving the organization) of higher education employees, namely, from universities and higher education schools. This approach included the terms, “job satisfaction”, “organizational commitment”, “university”, “college”, “faculty member”, “intention”, “turnover intention” and “college”. Organizational commitment and employee satisfaction in knowledge organizations, as well as trust in top management, are able to anticipate the intention to remain or leave the workplace.

Job satisfaction is one of the three most important predictors of well-being, alongside marriage and family [1]. Job satisfaction can be defined as a result of experiences and emotions experienced in the work environment that affect social life, affective bonds and mental health [2]. The present study aimed to analyze Job Satisfaction and to identify the factors that most contribute to improve the level of job satisfaction. To achieve these objectives, a quantitative and cross-sectional study was carried out based on a probabilistic sample of 105 Portuguese employees from a higher education institution out of 783. Therefore, the sampling error, for a confidence level of 95%, was 8.9%. The data collection took place from October 22, 2021 to January 4, 2022 and involved the administration of a digital questionnaire comprising two sections to all the employees. The first section includes questions related to the respondent's demographic and professional situation (gender, age, workplace, professional category, work functions, length of service, length of service in the same professional category, type of employment contract). The second section included the Job Satisfaction Scale (JSS) developed and validated by Siqueira [2]. This scale consists of 25 items and the answers were coded using a Likert scale ranging from 1 (strongly disagree) to 7 (strongly agree). Procedures of exploratory analysis and reliability analysis were used. Employees were aged between 28 and 66 years old, with an average age of 47.9 (SD = 8.5). As for length of service, by professional category, the average recorded was 9 years (SD = 7.5). Globally, the average length of service exceeds 36 years, however, the length of service varies from 1 to 43 years. The majority, 58.1% of respondents were female and 41.9% were male. In terms of professional category, the three most representative, with more than 10% of the answers, were: Auxiliary Professors (37.1%), Invited Assistant Professors (17.1%) and Technical Superior (11.4%). Taking into account the type of work function, the overwhelming majority was teacher (72.4%) from Health School (23.8%), Technology and Management School (22.9%), Agriculture School (21.0%) and Education School (18.1%). Finally, regarding the type of employment contract, it can be seen that the majority have an employment contract for an indefinite period or uncertain-term contract (64.8%). According to the results obtained, only 20% of employees were satisfied. The factors that most contributed to increase the level of satisfaction were: satisfaction with the nature of work (mean = 4.6; SD = 1.0), satisfaction with colleagues (mean = 4.5; SD = 1.2) and satisfaction with managers (mean = 4.3; SD = 1.6). Factors such satisfaction with promotions (mean = 2.9; SD = 1.6) and satisfaction with salaries (mean = 3.2; SD = 1.6) were the ones that most contributed to the reduced level of job satisfaction (mean = 3.9; SD = 1.1).

As instituições de ensino superior estão na base do desenvolvimento social e económico das Economias, na formação de recursos humanos (Nawaz et al., 2020) e na evolução e expansão do conhecimento científico. Entender as necessidades e os desejos dos professores e demais colaboradores é essencial (Carlos & Rodrigues, 2012) para garantir o seu crescimento e sobrevivência (Leite et al., 2015). Objectivos Pretende-se determinar o nível de Comprometimento Organizacional (CO) dos professores de uma instituição de Ensino Superior Pública e identificar fatores que contribuem para reduzir o nível de CO. Metodologia É um estudo transversal, aplicando um questionário que incluiu o modelo tridimensional desenvolvido por Meyer e Allen (1991), tendo obtido 76 respostas. resultados A maioria era do género feminino, categoria Professor Adjunto (51,3%) e com vínculo a tempo indeterminado (61,8%). Exerciam as suas funções letivas e de investigação em diversas áreas científicas, designadamente, Tecnologias e Gestão (26,3%), Saúde (25,0%), Educação (23,7%), Agrária (21,1%), Comunicação, Administração e Turismo (3,9%). A idade dos professores estava compreendida entre os 30 e os 66 anos, com média de 49,5 anos (DP = 8,05). O tempo de serviço foi em média, de 20 anos (DP = 10,18). Os resultados obtidos refletem uma boa consistência interna do modelo (Alfa de Cronbach > 0,7), registando-se um comprometimento organizacional moderado nas três subescalas (afetiva, calculativa e normativa) e no modelo global. Foram identificados 7 fatores que mais contribuem para diminuir o nível de CO, 4 fazem parte da dimensão normativa e 3 estão associados à dimensão calculativa. conclusões Recomenda-se a implementação de medidas convincentes, produtivas e eficazes por parte da Gestão da Instituição de Ensino Superior e do Governo Central, em especial, no que diz respeito à evolução da carreira docente Palavras-chave : Comprometimento organizacional, Ensino superior, Professores, Organizações públicas info:eu-repo/semantics/publishedVersion

Currently, higher education organizations face several challenges in trying to improve their organizational capacity, disseminate knowledge and encourage community service (Pucciarelli & Kaplan, 2016; Lesley, 2018; Kaplan & Haenlein, 2016). In this sense, the organizational commitment of employees can be decisive for the success of organizations since it is considered an important tool to achieve organizational goals. The present study aimed to determine the level of organizational commitment of employees of a Public Higher Education institution, located in the Northeast Portugal and to determine whether the type of employment contract is a differentiator factor of the organizational commitment. Therefore, a quantitative, observational and cross-sectional study was carried out based on the application of a questionnaire. Subsequently, 105 responses were obtained. The questionnaire included the scales of organizational commitment of the three-dimensional model developed by Meyer and Allen (1991). The results showed that the respondents' global commitment to the organization, in general, was moderate. Taking into account the three dimensions of the model, employees recorded higher levels of affective commitment, moderate levels of calculative commitment and lower levels of normative commitment. Additionally, it was found that the type of employment contract was different in only two of the three dimensions of the three-dimensional model of organizational commitment, namely, normative and calculative.

The Bioeconomy, in addition to being considered a means to achieve industrial competitiveness, offers new approaches to deal with future challenges, replacing fossil fuels with sustainable and renewable fuels and resources. A bibliometric study was carried out to describe the scientific production related to stakeholders’ perceptions about Bioeconomy and to group the existing literature into thematic clusters. 67 articles were selected from the Scopus database based on the words “Bioeconomy” and “Perceptions”. The VOSviewer software, version 1.6.18 was used to perform the bibliometric analysis. Four clusters were identified. The first cluster comprised the articles referring to the perceptions about the Bioeconomy of the timber sector stakeholders and of the different actors in the field of forestry action closest to the Bioeconomy area. The second cluster included articles related to the stakeholders’ perception of the Bioeconomy, namely, Civil Society in general and higher education students in particular, as well as their opinions on the importance of the forestry sector for the Bioeconomy. The third cluster comprised the articles that consider the Bioeconomy to be the innovative way to go to ensure the sustainability of the planet, therefore highlighting the importance of knowing the perceptions and raising awareness of all stakeholders to ensure the successful transition to the Bioeconomy. Finally, the fourth cluster included articles related to the perception of the Bioeconomy, consumer attitudes and behaviours regarding the acceptance of new biofood products resulting from the Circular Economy. info:eu-repo/semantics/publishedVersion

Nowadays, Information and Communication Technologies (ICT) are fundamental in all areas of study of the higher education system, playing a central role in learning and teaching. The proper use of ICT, in conjunction with modern teaching practices, can increase the efficiency of teaching and learning processes in higher education. Higher education acts on three dimensions, namely, the integration and use of new educational technologies in higher education; European convergence and the application of ICT; and innovation and education necessary to bridge the gap between higher education institutions and teachers, both socially and professionally. The main objective of this study was to investigate the current status about digital competence of higher education teachers. This short review was based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. From the definition of the objectives, the Scopus database was screened. The searches were performed in November 2021, using the combination of the keywords “ICT”, “skills”, “digital”, “literacy”, “education”, “higher” and “teachers”, as well as their synonyms. Initially, 37 publications were identified. At this stage, the following screening criterion was considered: sample constituted by higher education teachers (public and private). To identify publications that included only higher education teachers, abstracts and, when necessary, the entire text were selected. Afterwards, 26 studies were removed, leading to 11 eligible publications. The results indicate that, although digital competences are part of the current professional profile of higher education teachers and the transition to digital education is an inevitable trend in modern education, higher education institutions must continue to support teachers so that they can develop their skills. This way, online teaching and other forms of teaching and learning that have emerged from the digital age can be used to explore the opportunities presented by technology in order to improve the quality of teaching and learning. Given the almost universal use of e-learning in higher education, the literature highlights the importance of digital skills for higher education teachers who can act as teachers of the future, better preparing students for the labour market and creating a new generation that can participate effectively in online communities and other e-governance devices that promote democracy, equity and social justice. This literature review will serve as the basis for the preparation of an empirical research involving teachers from five higher education schools from Instituto Politécnico de Bragança, a higher education institution located in the inland North of Portugal (Agriculture, Education, Technology and Management, Administration and Tourism, and Health). With the development of this future research, which will aim to analyse the level of digital skills, attitudes, the difficulty of using technological tools in an educational context, it is intended to collect information that can be used to define strategies to improve digital skills among teachers from higher education.

A região de Trás-os-Montes apresenta uma gama de produtos certificados de elevado valor cultural e comercial. O queijo Terrincho de Denominação de Origem Protegida (DOP), fabricado com leite de ovelha Churra da Terra Quente é um desses produtos. Assim sendo, esta investigação tem por objetivos definir o perfil do consumidor do queijo Terrincho DOP e estudar os seus hábitos de compra e consumo. Para atingir esses objetivos, foi desenvolvida uma investigação analítica e transversal. Os dados foram recolhidos com recurso a um questionário estruturado por meio de entrevistas pessoais realizadas a uma amostra aleatória de consumidores da cidade de Bragança em março de 2019. Dos 380 entrevistados, 57 eram consumidores de queijo Terrincho DOP. Estes consumidores eram maioritariamente do sexo feminino (56%) e tinham, em média, 58,3 (DP = 16,2) anos de idade. Estavam casados (70%), empregados (50%), residiam no concelho de Bragança (90%) com 2 (40%) ou 3 (28%) pessoas no seu agregado familiar. Os consumidores de queijo Terrincho DOP diferem significativamente (p-value < 0,05) dos não consumidores por possuírem escolaridade de nível superior (53%), rendimento familiar mensal superior a 1200 euros e estarem reformados (47%). A frequência de consumo do produto ocorria uma vez ao mês (33%) ou duas a quatro vezes ao ano (26%), enquanto a frequência de compra ocorria mensalmente (69%). No momento da compra, a maioria dos entrevistados optou pelo produto certificado (67%) pela segurança (79%) que a certificação representa. Dada a sua aceitação pelos consumidores, o q queijo Terrincho DOP revela ser um produto capaz de gerar elevado valor acrescentado contribuindo positivamente para o desenvolvimento económico da região de Trás-os-Montes. The Trás-os-Montes region has a range of certified products of high cultural and commercial value. Terrincho cheese with Protected Designation of Origin (DOP), made with Churra da Terra Quente sheep's milk, is one of these products. So, the aim of this research was to define the consumers profile of Terrincho DOP cheese and study their purchasing and consumption habits. To achieve these objectives, an analytical and transversal research was carried out. Data were collected using a structured questionnaire through personal interviews to a random sample of consumers from Bragança city during March, 2019. Of the 380 respondents, 57 were consumers of Terrincho PDO cheese. These consumers were mostly female (56%) with an average age of 58.3 (SD = 16.2) years old. They were married (70%), employed (50%), lived in the municipality of Bragança (90%) with 2 (40%) or 3 (28%) people in their household. Consumers of Terrincho PDO cheese differ significantly (p-value < 0.05) from non-consumers because they have higher education (53%), a monthly family income above 1200 euros and are retired (47%). The frequency of consumption of the product occurred once a month (33%) or two to four times a year (26%), while the frequency of purchase occurred monthly (69%). At the time of the purchase, most respondents choose the certified product (67%) for the safety (79%) that certification represents. Given its acceptance by consumers, the Terrincho PDO cheese proves to be a product capable of generating high added value, contributing positively to the economic development of the Trás-os-Montes region.

Sharing economy describes a recent phenomenon in which ordinary consumers start to act as salespeople, providing services previously owned exclusively by professional sellers. It is considered a person-to-person activity of obtaining, giving, or sharing access to goods and services, strengthen by the use of online platforms/services. This system allows, on the one hand, to reduce the waste associated with lack of use. In addition to enabling the increase of products’ use durability by ensuring that they are used to their full potential. Through the fast pace of people's lives, the sharing economy has flourished unprecedentedly and plays a significant role in the business market. In this context, this paper aimed to identify the motivations of Portuguese higher education students for the practice of sharing economy, and to verify if gender is a differentiator factor as for the use of shared services. To achieve these objectives, a quantitative and analytical research was developed. To collect the data a questionnaire, created on Google Forms, was applied through social networks and e-mail from March to June, 2021. IBM SPSS Statistics 27.0 software was used for data analysis that involved the use of descriptive statistics and the Chi-square test at the significance level of 5%. A total of 489 valid answers were obtained. The students were aged between 18 and 59 years old, with an average age of 21.9 (SD = 3.3), and the majority were female (57.9%). The results showed that most of the respondents are familiar with the term of sharing economy (59%) and that regularly, in the last week or month, they have recycled (79%), reused (76%), and repaired (64%) goods. Most of the individuals have already used sharing services, namely, "online buying and selling service of new and used products", for example, the OLX website (66%), and "ride-hailing service", for example, Uber's services (56%). Factors such as trust, usefulness, quality of service, environmental impact, minimization of costs, internet capacity, and familiarity with this type of service, lead consumers to shared economy practices. On the other hand, it was later confirmed that the three main consumers’ motivations, which determined the choice of a sharing business, were the creation of employment, the positive environmental impact, and the possibility of reusing already existing resources. Finally, concerning the use of sharing services, it was concluded that gender is a differentiator factor in what concerns to the bicycle-sharing service (p-value = 0.031). In fact, it was male students (23%) who used this service in greater proportion compared to female students (15%). For the success of the sharing economy, it is important that consumers have confidence in the platforms used in the dissemination of products and services, and that these are of quality, otherwise consumers will no longer purchase them.

Worker absences are costly and disruptive for Public Administration, and the trend has steadily increased over the years (Hassan, Wright & Yukl, 2014). In Portugal, the absenteeism is also increasing in public administration. For this reason, the Portuguese government recommends to public services managers the use all legal instruments that allow addressing the different needs of their workers, namely work provision regimes and working hours. So, given the scarcity of studies developed on absenteeism and satisfaction with work in local municipalities, this research aimed to analyze the association between absenteeism and the level of satisfaction with work and to verify if the satisfaction with work varies according to the municipalities size. To achieve these objectives a cross-sectional and quantitate study was carried out based on a sample of 245 workers from 6 Portuguese municipalities located in the Bragança district. To collect the data, a questionnaire was applied from April 2018 to July 2019. Data analysis involved the use of the IBM SPSS Statistics software. On average, the number of absences from work was 15.4 days at the medium-sized municipality and 13.2 days at the small-sized municipalities. It was verified a high level of satisfaction with work among municipalities workers. However, the municipality size revealed not to be a differentiator factor of the absenteeism and satisfaction with work. The main reason associated with the absence was the need to support the family, natural illness, prolonged illness, demotivation and/or dissatisfaction with work, among others. Also, no correlation was found between the satisfaction with work and absenteeism.

Well-being, involvement, commitment or happiness of workers are themes that have produced a growing interest in research in the field of management (Kolodinsky, Ritchie & Kuna, 2018; Lee, Park & Baker, 2018). So, this study was carried out in order to verify findings in the literature such as: the happiness at work enables the attainment of personal and professional goals and contributes to organizational success (Veld & Alfes, 2017); self-employment is highly valued due to the self-determination and autonomy it provides (Benz & Frey, 2008); self-employed individuals have higher levels of job satisfaction but self-employment does not provide a greater satisfaction with life because these workers work more hours and their leisure time is relatively shorter (Zwan, Hessels & Rietveld, 2018). To achieve this objective, a search was carried out on two databases, namely Scopus and Web of Science (WoS) in May 2020, based on the terms "Entrepreneurship", "Happiness" and "Work". In Scopus database, 14 publications were counted and in WoS database, 25 publications were found, of which 6 were duplicated in both databases. A bibliometric analysis was developed using the VOSviewer software version 1.6.15 and the co-occurrence technique of “full-counting” terms was used in order to build a map that shows the association between the different terms and their grouping into clusters of thematic areas based on 33 publications. Two clusters of terms have been identified. The first cluster relates happiness with being an entrepreneur, employee and independent professionally. And, the second cluster relates self-employment with satisfaction with life.

Currently, digital skills are considered a decisive requirement for personal fulfillment and development, active citizenship, social inclusion and employment in the knowledge society. In this context, this research aimed to consolidate the existing research in the field of digital literacy among teachers. In methodological terms, this research was based, in a first stage, on the PRISMA statement and, in a second stage, on bibliometric analysis. For this, a search was developed, in March 2021, in the Scopus database being selected 96 publications based on the combination of the terms "ICT", "skills", "digital", "literacy", "education" and "teachers". Subsequently, a chronological filter was used limiting the research period from 2010 to 2020 being counted 80 publications. Then, this research was limited to “Article” and “Review” documents subject to double blind referee (46) published in English, Spanish, Portuguese and French (44). Finally, abstracts and, when necessary, the entire text was selected, in order to verify the relevance of publications for this research, considering the following criteria: study location, type of study, objectives, sample size and contributions, totaling 27 articles. The elaboration of the bibliometric analysis was done using the VOSviewer software, version 1.6.16 and the binary counting method. The minimum number of occurrences was set at five. Three thematic approaches that were related to each other were identified. The first included the terms "Area", "Communication", "Communication technology", "Digital competences", "Information", "Level" and "Training". This approach covered all publications that used instruments to measure the level of digital skills of teachers and identified factors that are determinants of these skills, namely, the area of training, the level of education in which teachers work, teaching experience, age, gender, among others. The second approach included the terms "Attitude", "Experience", "ICT integration", "ICT skills", "Implementation", "New Technology" and "Teacher training". In general, these publications described the digital literacy practices of teachers, the difficulties of implementation, with special attention, on teachers’ knowledge and attitudes. Finally, the third approach focused essentially on the question "how to equip teachers with the knowledge and skills needed in the digital age?" This approach included all publications with the terms, "Learning", "Process", "School" and "Technology", being associated, especially to the use of technologies in the classroom as an instrument to improve digital learning, which promotes changes in digital thinking and behavior between teachers and students, despite the existing challenges and limitations, such as the inadequate installation of ICT, time restrictions, the actors’ limitation of competencies, the attitudes and motivation of teachers in the use of technologies, among others.

This research aimed to consolidate the existing research in the field of organizational commitment and job satisfaction in health professions. A systematic review of the literature was used by combining the bibliometric technique, using the binary counting method. The first cluster relates organizational commitment to job satisfaction and included thirteen terms, namely "Employee", "Employer", "Implication", "Information", "Intervention", "Job", "Job satisfaction", "Order", "Organizational commitment", "Perception", "Person", "Relationship" and "Satisfaction". In general, this cluster included articles that identify factors associated to job satisfaction and analyses the association between the dimensions of job satisfaction and organizational commitment. The second cluster associates professional commitment and job dissatisfaction and included nine terms, namely, "Athletic trainer", "Demand", "Experience", "Patient", "Perspective", "Professional commitment", "Responsibility", "Time", and "Workplace". This cluster covered all publications that reported individuals' commitment to the profession- These professionals feel proud of their work which they consider demanding and of great responsibility. But, they also expose their dissatisfaction at work. However, despite the dissatisfaction, they are available and able to embrace new challenges.

Hábitos alimentares variam por diferentes fatores complexos, dependendo de motivações pessoais e do contexto em que o indivíduo está inserido na sociedade. O pão é um dos alimentos mais antigos e mundialmente conhecidos, consumido de diversas formas e frequências. Esse estudo teve como objetivo conhecer os gostos, preferências e hábitos de consumo e compra de pão na cidade de Bragança - PT. Foi desenvolvido um estudo quantitativo e transversal a partir de um questionário aplicado de forma exclusivamente online, devido à ocorrência da pandêmica de COVID-19, alcançando 215 consumidores que adquirem produtos alimentares no Município de Bragança. O questionário disponível encontrava-se estruturado em três seções: Na primeira, questões sociodemográficas para caracterização do inquirido; a segunda, questões associadas ao gosto, preferências e hábitos de consumo; e por fim, a terceira parte incluía questões relacionadas com os hábitos de compra. A recolha de dados decorreu de junho a agosto de 2020. A amostra foi obtida através de uma amostragem não probabilística tipo bola de neve. O programa utilizado para editar e tratar os dados foi o IBM SPSS versão 26.0, utilizando o teste Qui-quadrado de Pearson, ao nível de significância (a) de 5% para comparar proporções. A maioria dos consumidores eram portugueses (67%), do sexo feminino (61,9%), vivia em zona urbana (85,6%) e gostava de pão (99,1%). O pão de trigo (72,1%) e o pão integral (64,7%) se mostraram os mais consumidos, os pães da região mais conhecidos e mais consumidos são o pão Nogueira, Rebordainhos e o Argozelo. A maioria dos consumidores afirmou consumir pão pelo menos uma vez ao dia (62,3%), 1 a 2 fatias / pães (76,7%), geralmente no café da manhã (67,9%). O tipo de acompanhamento preferido são as gorduras vegetais (66,5%) e os lácteos (65,6%). Os atributos mais valorizados foram a frescura (92,2%), o cheiro a pão fresco (87,6%), a textura fofa (80,8%), a crosta crocante (76,1%), o preço (56,2%) e a durabilidade (55,2%). A maioria dos consumidores compra pão no supermercado (55,2%), sendo a qualidade do pão (96,9%) e a higiene e limpeza do espaço (93,7%) os fatores mais valorizados pelos consumidores na hora da compra. Pôde verificar-se, nesta investigação, que determinados hábitos de consumo e de compra do pão estavam, de facto, associados às características sociodemográficas do inquirido. O pão regional é adquirido, em maior proporção, por indivíduos com idade superior a 35 anos, ativos e que fazem parte de agregados familiares que incluem menores de idade. Já o pão industrial, se mostrou mais consumido por estrangeiros, homens, pessoas que moram sozinhas e por agregados familiares de maior dimensão. info:eu-repo/semantics/publishedVersion

As tecnologias de informação e comunicação revolucionaram a forma de fazer negócios. O desenvolvimento do comércio eletrónico e o uso massivo da Internet aumentaram a popularidade das compras online em todo o mundo. Por isso, esta investigação teve como objetivos avaliar os fatores que afetam o uso futuro do comércio eletrónico por estudantes do ensino superior em Portugal e, verificar se existem diferenças tendo em conta a nacionalidade, género e idade dos inquiridos. Para isso, foi desenvolvido um estudo quantitativo, transversal e analítico baseado numa amostra por conveniência constituída por 304 não entusiastas da compra online. Apesar de não ser entusiasta da compra online, a maioria dos inquiridos, já é utilizador assíduo da internet há 5 ou mais anos. Contudo, entende que o seu nível conhecimento na realização de compras online é, ainda, muito limitado. As barreiras à compra online mais valorizadas pelos estudantes foram gostar de ver e experimentar os produtos antes de os comprar, falta de confiança nos sistemas de pagamento e nos sites de comércio eletrónico, preocupação com a segurança e privacidade e preferência pelo atendimento presencial. Existem barreiras à compra online nas quais foram identificadas diferenças tendo em conta a nacionalidade, o género e a idade dos estudantes.Information and communication technologies have transformed the way of doing business. The development of e-commerce and the massive use of the Internet have increased the popularity of online shopping around the world. This research aimed to evaluate the factors that affect the future use of electronic commerce by students of higher education in Portugal and to identify differences taking into account the nationality, gender and age of the respondents. A quantitative, cross-sectional and analytical study was developed based on a convenience sample consisting of 304 non fans of online shopping. Despite not being enthusiastic about online shopping, most of the respondents have already been a regular user of the internet for 5 or more years, however, they understand that their level of knowledge in making online purchases is still very limited. The most valued barriers to online shopping by students were enjoying seeing and trying products before buying them, lack of confidence in payment systems and e-commerce sites, concern about security and privacy and preference for face-to-face service. There are barriers to online shopping in which differences have been identified taking into account the nationality, gender and age of students.

Purpose: This research aimed to identify the most developed themes in the fields of Entrepreneurship, Happiness and Work. Methodology: To achieve these objectives, a search was carried out on two databases, namely Scopus and Web of Science (WoS) in May 2020, based on the terms "Entrepreneurship", "Happiness" and "Work". In Scopus database, 14 publications were counted and in WoS database, 25 publications were found, of which 6 were found simultaneously in the Scopus and WoS databases. A bibliometric analysis was developed using the VOSviewer software version 1.6.15 and the co-occurrence technique of “full-counting” terms was used in order to build a map that shows the relation between the different terms and their association in clusters of thematic areas based on 33 publications. Originality: Since the well-being, involvement, commitment or happiness of workers are themes that have produced a growing interest in research in the field of management, particularly, in the field of human resources (Kolodinsky, Ritchie & Kuna, 2017; Lee, Park & Baker, 2017) this original study was carried out in order to verify findings in the literature such as: the happiness at work enables the attainment of personal and professional goals and contributes to organizational success (Veld & Alfes, 2017); self-employment is highly valued due to the self-determination and autonomy it provides (Benz & Frey, 2008); self-employed individuals have higher levels of job satisfaction but self-employment does not provide a greater satisfaction with life because these workers work more hours and their leisure time is relatively shorter (Zwan, Hessels & Rietveld, 2018). Findings: Two clusters of terms have been identified. The first cluster relates happiness with being an entrepreneur, employer and independent professionally. And, the second cluster relates self-employment with satisfaction with life. Practical implications: This study contributes to consolidate the state of art in the fields of entrepreneurship, happiness and work/employment. Also, this study allowed taking into account quantitative studies developed in order to identify the relations between these fields.ACKNOWLEDGEMENTS The authors are grateful to the Foundation for Science and Technology (FCT, Portugal) for financial support by national funds FCT/MCTES to CIMO (UIDB/00690/2020).
