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 paper aims to monitor the urban landscape through the perceptions of residents and visitors, identifying features that cause visual impacts and providing insights for landscape management decision-makers. Captured impressions about the city whilst moving around are important to assess the satisfaction of city residents and city visitors through key elements, such as directional signage, outdoor advertising, restaurants’ outdoor terrace furniture, urban furniture, green spaces, traffic, cleaning, pedestrian areas, visitor flow and conservation of monuments, museums and buildings.

A survey was applied in the historical Porto city centre (Portugal) to understand residents’ and visitors’ perceptions of the city landscape and assess the differences between these two groups. Cronbach’s alpha was used to assess the reliability of the constructs (dimensions) of urban landscape. Non-parametric Mann-Whitney test was used to find significant differences in the perceptions of residents and visitors.

The results suggest significant differences in the perceptions. Residents value more two constructs of the landscape (heritage conservation and transport mobility) whilst visitors value more other two (pedestrian mobility and aesthetic quality). It is showed that residents have a strong sense of place and are concerned with the conservation of historical heritage. Visitors are more concerned with dimensions intrinsically related to tourism.

This research allowed to fill a gap found in the literature, namely, the importance of considering the perceptions of different actors in the urban landscape monitoring. These results are an important contribution for local authorities to understand the value of urban landscape elements from the perspective of residents and visitors. This study opened the possibility of comparing the results from different historical cities centres.

The purpose of this paper is to contribute to the relaxion on what can be done to develop ethical cultures that may be less permeable and more resilient to changes in leadership from an ethical point of view. The influence of leaders on organisational ethics is recognised, and there are even those who consider that it is not possible to maintain an ethical culture when leaders are not engaged. But, if this theory is true, all business ethics programmes that can be created, and the cultures that can gradually be developed in organisations, will always have their existence and robustness suspended at each leadership change. How to maintain an ethical culture beyond leadership?

As a strategy, we used the case study with a narrative methodology, in which a chief executive officer (CEO) and a chief compliance officer (CCO) narrate in the first person a case of perceived collapse of the ethical culture of a multinational company.

The findings point to the difficulty in maintaining ethical leadership. Key aspects to protect an organization from leadership changes are as follows: the management of the succession process, the quality of the training on ethics and the mechanisms developed by the organization to foment speak up and take notice of the situations. Moral blindness and the banality of evil that also can be observed in organizations appear as facilitating elements for collapse.

Ethical leadership is generally presented as a necessary condition for an ethical culture. However, leaders often have unethical or ethically neutral leadership. This case helps to understand the difficulties experienced by leaders in adopting ethical leadership and proposes a set of instruments and procedures that, when included in an ethical programme, can protect the company's ethical culture against unethical leaders. Some characteristics of our case study make it particularly relevant: action occurs in a multinational, a context where, by size and complexity, achieving uniformity in culture becomes particularly relevant, and actions happen in the context of a CEO succession process, something that may occur in any company and which is often a trigger for ethical misconducts. Additionally, our case is narrated by a CEO and a CCO, which makes it rare, as it is especially difficult to have access to these executives.

Jambolan has be used as a diabetes-treatment aid, and it has become quite popular; studies have been carried out over the years on this fruit because it presents high activity against superoxide anion and hydroxyl radicals due to the bioactive compounds that may play an important role against oxidative stress. No studies have been reported on the effects of pasteurization on the bioactive compounds of jambolan tropical juice. The paper aims to discuss these issues.

For evaluation of the effects of pasteurization on jambolan juice bioactive compounds, a complete compound and rotational experimental design was carried out by varying temperature (80–90°C) and time (45–75 s). The bioactive compounds (total phenolic, total anthocyanin and antioxidant activity) and the enzymatic activity of enzymes (enzymatic browning) were assessed.

The study of bioactive compounds in the pasteurized juice of jambolan, showed that the total phenolics (TP) and ABTS antioxidant activity presented statistical significance (p<0.05). The action of enzymes causing enzymatic browning was only observed in the standard sample. The optimization of the pasteurization process with the maximum bioactive compound retention was 91.65°C for 69.45 s. The optimal point found is in agreement with studies on thermal treatment that recommend using short times at high temperatures for better retention of food constituents.

The incidence of chronic diseases in humans has increased significantly over the years, some bioactive phytochemicals present in fruits may help against these diseases, so the production of tropical jambolana juices can help to nourish and regulate the consumer health. Therefore, studying the maintenance of bioactive compounds present in this product could be an alternative for the production of healthier foods.

Many start-ups do not survive the first few years of business. Previous studies suggest that networks play a role in start-ups' success, but this positive effect has limits. The purpose of this paper is to answer the call for a better understanding of the dark side of networks and the variables that condition variables' effect on the likelihood of start-ups' survival.

A longitudinal research design includes 139 start-ups (102 from Germany and 37 from Portugal) and a total of 252 participants. A generalized linear mixed model (GLMM)was applied to estimate all the coefficients, to test the mediation (H1), the moderation (H2) and the moderated mediation (H3) while considering the economic situation of the start-up (sales growth), start-ups' networking behavior, creativity orientation and ultimately the likelihood of survival.

Based on an empirical study from two different countries, the results show that effective networking is contingent on the start-up's economic situation and creative potential. Specifically, the results point to situations in which early sales growth may lead to external networking, which, in contexts of low creativity-oriented start-ups, can compromise the start-ups' success.

Based on the findings, the authors compare scenarios in which networking increases the chances for start-up survival with situations where networking can have adverse effects. This study highlights the importance of considering specific start-up parameters, such as start-ups' economic situation and level of creativity orientation, in the business venturing literature.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

The purpose of this study is to evaluate the effect of the probiotic addition (Lactobacillus paracasei ssp.) on the physicochemical characteristics and antioxidant capacity of white grape juice during refrigerated storage (4°C/28 days). This paper also aims to evaluate the survival of the probiotic culture in the product and under simulated gastrointestinal conditions.

Two formulations of white grape juices were evaluated, one with 2 per cent of probiotic culture addition and the other of pure juice.

The addition of probiotic culture resulted in products with a darker-reddish coloration (L* = 30.6-30.8 and a* = 0.6-0.9) and a lower content of total phenolic compounds (599-697 µg EAG mL⁻¹) (p = 0.05). However, it improved the color stability and maintained the antioxidant activity 1,1-diphenyl-2-picrylhydrazyl (p > 0.05). The viability of the probiotic culture (>10⁹ colony forming unit · 200 mL⁻¹) in the juice was maintained during 21 days of storage, but in simulated gastrointestinal conditions, the functional properties could be guaranteed during the 28 days of refrigerated storage.

The white grape juice is a suitable medium for incorporation of Lactobacillus paracasei.

The survival of the probiotic cultures to the simulated gastrointestinal tract may be significant, even if the product does not have the recommended minimum counts.

The purpose of this paper is to examine the conditions for Native American high school students that result in successful adaptation to an online learning environment.

In total, eight Native American students attending high schools located on Montana Indian reservations, and one urban city, were interviewed. Participants completed online coursework through Montana Digital Academy (MTDA). A theoretical model illustrates the successful adaptation of Native students to online learning.

Students' learning needs and the online learning environment were congruent. Course offerings at local high schools were limited, resulting in boredom and lack of challenge. Students wanted new and interesting coursework and learning online met those needs. Students worked at their own pace and ability levels and enjoyed the challenge, freedom, and independence resulting from learning online. Students who frequently missed school were easily accommodated.

Students' orientation toward education, such as attitudes toward learning and school, family influences, and interactions with classroom teachers, affected the adaptation process. Participants felt empowered and had more positive expectations for their future as a result of learning online. This was caused by: feelings of independence working without face‐to‐face contact from a teacher; confidence gained when successfully completing assignments; and control felt from being in charge of their own learning.

This paper describes college‐bound Native American high school students' online learning experiences; research on this topic is practically non‐existent. The findings can benefit those who lack understanding of how Native students adapt to an online environment; educators are better equipped to create supports that promote academic success for Native American students.
