The purpose of this study is to investigate international trade determinants, paying special attention to variables related to climate change and non-tariff measures (NTMs), as they shape more and more world trade flows, with particular incidence on globalised goods, such as wine.

Based on panel data of Port wine exports to 60 countries, between 2006 and 2018, a gravity model has been estimated through Poisson pseudo-maximum likelihood. Explanatory variables include NTMs, mean temperature, temperature anomaly, gross domestic product (GDP), exchange rate, ad valorem equivalent tariffs and home bias.

The findings show that exports are inversely related to both mean temperature and temperature anomaly in importing countries. Regarding NTMs, it is found that only part of them are trade deterrent. Additionally, purchasing power in importing countries is one of the main determinants of Port wine exports.

The results show that, besides traditional economic variables, policymakers and wineries should include in their exports' decisions the impact of variables related to climate change and NTMs.

The novelty of this paper is to incorporate the impact of climatic variability of importing countries as a determinant of international trade of wine. Most former studies inspired of the gravity model consider explanatory variables such as GDP and exchange rate, and more recent ones started to consider NTMs too, however, this study may be the first paper to include the impact of climate change (quantified by mean temperature and temperature anomaly in importing countries) on exports.

The purpose of this paper is to contribute to the determinants of export performance literature. The authors investigate the effect of firm characteristics on the Douro region wine firms export performance. The authors consider the Douro region, as it has the Portugal highest wine classification, the appellation d’origine contrôlée and undertakes the first position in the Portuguese wine production and export.

The authors apply a pooling cross-sectional data set that includes 427 observations. The authors pooled two cross sections consisting of 214 and 213 firms for the years 2014 and 215, respectively. The firm export intensity and propensity are the dependent variables. Moreover, the firm size, age and productive efficiency are accounted as the firm characteristics. The authors use the ordinary least squares regression and the tobit and probit models for estimations.

First, size is an influential factor to improve the export performance, and the importance of size is higher for younger firms. Second, there is a positive response from export intensity to age and this response is higher for smaller firms. However, there is a negative response from the export propensity to age and this negative response is higher for bigger firms. Third, there is weak evidence to support a relationship between efficiency and export performance.

This research and the presented results are undoubtedly under some limitations. The main limitation is about the data availability for all characteristics of a firm. For example, it will enrich the result if the authors add some other important variables such as production cost, research and development expenditure and the quality of produced wine by each firm to our analysis.

This research reveals that the influence of firm characteristics on the export performance of Portuguese wine firms is missing in the literature. The results provide a basis to Portuguese wineries to improve their export performance by applying the relevant strategies.

The purpose of this paper is to empirically examine the macroeconomic determinants of Port wine exports, taking into account the diversity and various quality levels associated with this product.

Port wine is a fortified wine only produced in Portugal. In the period 2006-2014, an extended gravity model is applied to data on the exports of the top 20 importing countries, accounting for 94 per cent of total exports. The authors base their empirical strategy on the Hausman–Taylor estimator (1971), overcoming endogeneity and accounting for time invariant variables. They estimate the impact of several factors on the total trade of Port wine, namely: gross domestic product (GDP), GDP per capita, tariffs, exchange rates, distance from original supplier, mutual language familiarity, landlockedness, wine consumption per capita and presence of Portuguese emigrants, all measured in volume and value terms, and for each of the four categories (Standard, High Standard, Vintage and Aged).

The findings show that the quantity and value of total Port wine exports are positively determined by overall GDP per capita, the presence of a Portuguese emigrant community (which implies that to some degree a common language and culture are shared), while exports are negatively influenced by landlockedness. In contrast to the traditional gravity model, distance from the source of supply does not appear to be a significant determinant, a fact explained by the specific and singular nature of Port wine and by the long tradition of this product in international markets. In addition, the results revealed specific determinants for specific product categories – such as GDP for aged Port and wine consumption per capita for high standard, vintage and aged Port, suggesting that Portugal needs to increase its exports of high-quality Port wine to markets that exhibit a tendency towards increased wine consumption per capita and are coming to be considered large and fast-growing economies.

This paper extends the literature, by respecifying the typical gravity model for aggregate goods to permit the analysis of wine exports. There has been relatively little application of this model to assess the determinants of the wine trade, and when it has been used, generally it has been in studies focusing on aggregate wine trade between countries. This paper seeks to fill this gap by focusing on the determinants of exports of a specific wine – Port wine, which is an internationally recognised product, with a clear internal product differentiation according to distinct quality levels – and in this regard provides new insights into the international patterns of trade in wine.

The paper aims to present a literary itinerary inspired in Julio Dinis’ novel An English Family (Uma Família Inglesa) through a comparative analysis of the places identified in the novel and the touristic attraction proposed by Visit Porto website. This novel is representative of the cultural identity and society of Porto city in the 19th century. Developing an itinerary based on this novel can facilitate the reading and understanding of the historical and cultural development of Porto.

This case study is based on the reading of the Julio Dinis’ novel An English Family (Uma Família Inglesa), whose storyline takes place in Porto city, Portugal in the 19th century. It used QGIS v. 3.12 software, a geographical information system to identify the places, to produce the maps and to create the itinerary.

The comparison between the places identified in the novel and the tourist attraction in Visit Porto website revealed that only 6 points in the novel are referenced on Visit Porto website. These points correspond to the ones in the historical city centre of Porto. However, the creation of an itinerary that brings together all the points mentioned by Julio Dinis in his novel, will allow the development of a new touristic itinerary, alternative to existing itineraries in the city and that can be seen as a distinguish offer that allows a different view of the urban space of Porto.

There are some limitations to this study that can be highlighted. First, it was difficult to find the correct location of some points identified in the novel, due to difficulty of finding historical maps with quality of the data. At the same time, as tourist information is dispersed by several sources, and most of those data is not georeferenced, it was time consuming the integration of all the information in the same geodatabase. The choice of the shortest path can also be considered as a limitation, rather than the route followed by the author in the novel, but geographic information systems operates on spatial and temporal scale, which can present a limitation in tourism analysis. In the case of this project, we have chosen the shortest path, assuming that tourist would prefer that.

This research allowed to address two areas of knowledge that are emerging in the study of urban centres as tourist areas: the use of GIS and literary tourism. Despite the fact that there are already articles on this subject, the originality focuses on the approach made around one of the greatest writers of Portugal in the 19th century, allowing to present a tourist itinerary about one of his literary works, and the comparison made between the places identified in the novel and the tourist points identified on the Visit Porto website.

This study aims to examine how entrepreneurship education influences intentions for starting a technology venture among science, technology, engineering and mathematics (STEM) students with particular attention to gender differences. This study builds on the model of entrepreneurial event and social role theory to assess the impact of entrepreneurship education on feasibility, desirability and intentions for technology entrepreneurship.

The hypotheses are tested with a sample of 879 Bulgarian science and engineering students from 15 universities. To test the models, this study uses ordinary least squares and logistic regressions with robust standard errors and Hayes mediation analysis with bootstrap bias-corrected confidence interval estimations for indirect effects. Two-stage Heckman regressions to control for sample selection bias and other robustness checks including propensity score matching were used.

Results show that entrepreneurship education, measured as participation in an entrepreneurship course, has a stronger impact on feasibility, desirability and intentions for technology entrepreneurship for female STEM students compared to their male counterparts. As such, this study supports the notion that entrepreneurship education could be part of a solution to counteract societal norms that position technology entrepreneurship as a less desirable and/or less feasible choice for women in STEM. However, attention should be paid to the operationalization of entrepreneurship education, as other measures of entrepreneurship education (role models, entrepreneurship education support) did not have a moderation effect with gender.

The authors assume a positive correlation between entrepreneurial intentions and entrepreneurial behavior. Future studies should include actual entrepreneurial behavior to paint a more complete picture of the effect of entrepreneurship education.

Little is known about the role of entrepreneurship education in the field of technology entrepreneurship, and even less about the potential gender differences in entrepreneurship education among STEM students. The study contributes to the literature by examining factors that could help close the persistent gender gap in technology entrepreneurship.

Distance universities are of great importance for establishing sustainability literacy, as they operate as multipliers for thousands of students. However, despite several advantages of e-learning environments compared to traditional class-teaching, there are still challenges regarding suitable e-learning tools and didactical models. The purpose of this paper is to evaluate the effectiveness of several e-learning tools on students’ knowledge and skills growth and to compare two learning paths, synchronous vs asynchronous, exploring how each affects the level of students’ knowledge achievement and skills acquisition.

The empirical analysis is based on an online course “Participatory processes in environmental politics”. International MSc and PhD students who enrolled in the course were from FernUniversität in Hagen (Germany) and Aberta University (Portugal). The course was designed as the flipped classroom, applying different e-learning tools and activities, some synchronous and others asynchronous. A pre- and post-evaluation questionnaire was applied to evaluate students’ knowledge and skills. Descriptive statistical analyses were carried out on this data.

Results showed that in the synchronous group, knowledge about theoretical approaches to citizen participation and sustainable environmental governance improved to a greater extent, whereas the asynchronous group showed greater improvement in nearly all skills related to intercultural communication and e-learning. Also, in the synchronous path, students enhanced their knowledge on “research application” to a greater extent.

Evaluating the effectiveness of different e-learning tools on students’ sustainability knowledge and information and communication technologies skills is a fundamental issue. The study discusses these issues, contributing to enhancing the use of adequate and grounded e-learning models on sustainable development in higher education.

Post-traumatic stress disorder (PTSD) is associated with risk of suicide and chronic psychological impairment. The continued exposure to stress suffered by health-care workers (HCWs) during the COVID-19 pandemic can be considered a mass traumatic event and contribute to higher rates of PTSD in this population. The purpose of this research is to find out the prevalence and factors associated with PTSD among HCW in a general hospital.

The authors devised a survey to assess the prevalence of PTSD among HCWs in a general hospital and its relationship with sex, social support, profession, work experience in health care, time spent caring for COVID-19 patients and place in which the COVID-19-related activities were carried out. PTSD symptoms were assessed using the PCL-5, Portuguese version.

A total of 226 HCWs were included in the study. Provisional diagnosis of PTSD was made based on the PCL-5 responses, considering DSM-5 criteria and the cutoff score of 33. In total, 79 (35.0%) HCWs had a provisional diagnosis of PTSD, and a significant association was found between PTSD and time spent working with COVID-19 patients and between PTSD and place of work, namely, the COVID-19 emergency room and intensive care unit.

The results highlight the need for a reflection on the importance of mental health promotion among HCWs, specially in adverse conditions such as the current pandemic.

This paper aims to analyse the impact of institutional quality, economic factors and unemployment on entrepreneurial activity. The dynamic approach adopted in this study permits to evaluate the simultaneous influence of specific factors on total entrepreneurial activity.

A quantitative approach through a panel vector autoregression analysis was adopted to take into account possible endogeneity issues, and a short-run Granger test was used to test causality between variables to fill the theoretical and empirical gap about the joined and dynamic effect of institutional quality, economic factors and unemployment on total entrepreneurship activity as a dependent variable.

The use of a dynamic estimation approach demonstrates that three kinds of relative effects exist: durable and positive effects between industrial production index (IPI), stability and self-employment, a limited positive effect which exists during a predeterminant period between dimensions of institutional quality and unemployment rate (UR) and finally negative effects between IPI and UR.

In general, this study identifies three main effects: negative, temporary positive and perpetual positive. This is the same conclusion for the link between self-employment rates (SER) and institutional quality, measured by six dimensions. Three of these dimensions are especially important: political stability and the absence of violence, governmental effectiveness and regulatory quality.

In light of this study’s results and contrary to the idea admitted about the negative effect of unemployment on entrepreneurial activity, it seems that a relatively positive effect exists. By relative, the author means during a determinant period. It also has to be remembered that entrepreneurial activity was appreciated by the SER according to the recommendation of many previous researchers discussed at the beginning of this paper. Based on the model, three levels of relations emerge. This permits this study to dress a hierarchical list of alternatives to promote entrepreneurial activity. Economic policymakers have to reconsider the importance of the UR as the best occasion to create firms if good institutions and economic support are provided. Good governance and stability are the most important institutional determinants with a long positive effect. This conclusion suits Glaeser and Saks (2006) as well as Ojeka et al. (2019).

This research offers considerable scientific evidence to make decisions and orient decisions-makers about policies adopted to increase institutional quality, reducing unemployment and stimulate economic activity, but it is still necessary to reconsider these results for developing countries. It is hoped that future researchers enrich and reinforce the model to provide a critical pathway for successful entrepreneurship activity in this new normal. In the end, this crisis can be also treated as a good occasion to innovate and reconsider the thinking process to manage and operate in the economic world.

This study’s contribution is to help and assist economic policymakers to be aware of the relative importance of such determinants at the country level. The introduction of the relative importance of time is in agreement with the concept of entrepreneurial opportunity.

This paper aims to study the use of pumpkin pulp and its by-products in food formulation. Pumpkins are important and useful in the food industry. However, only the pulp is used, and the shell and seeds are wasted, which represents an important food waste.

A systematic review was performed by searching electronic databases relating to the physicochemical, textural and sensory effects of the pumpkin pulp and its by-products’ incorporation into foods. No human subjects were involved, and ethical approval was not required.

Pumpkin seeds and shell have been included in quite a variety of products. The primary effects on the physicochemical properties of bakery products, dairy products, beverages and snacks are the increase in energy, protein, iron, calcium, carotene content and textural properties (hardness, chewiness, snapping force and viscosity).

Limitations comprise the heterogeneity of the studies included, which causes varied results.

It was evidenced that pumpkin is already included in food products, especially in bakery products. However, there are not many products where the shell and seeds are used. Therefore, it is a field to be explored, as these by-products have great potential both to enrich food products and to reduce food waste contributing to sustainability.
