The literature on the factors that enhance ecogamification and the intention to use smart tourism applications is vast and increasing. However, most studies tend to focus on the “user”, rather than the “tourist”, and that gap is the trigger for the present research. The purpose of this paper is to examine how home and travel environmental behaviour, travel motivations, types of entertainment (digital and non-digital) and technology proficiency (professional vs non-professional) influence the receptivity of urban tourists to different game elements in a transport and mobility context.

The study carried out a qualitative experiment with focus groups, with a total of 16 urban tourists. The software webQDA was used to systematize and categorize data and to analyze the content.

The results suggest differences and similarities in terms of receptivity of urban tourists to ecogamification, which might have implications for future studies on urban tourists’ typologies and segments and also for providers of ecogamified services, game designers and marketers.

Rather than addressing the game elements per se (which, in this research, are seen as means to an end), the novelty resides in the combination of characteristics that intersect urban tourism (travel motivations), gamification (entertainment preferences and technology proficiency) and sustainability (home–travel environmental behaviour). This intersection provides a lens to interpret tourists’ receptivity and interaction with different game elements (cooperation, reward, points, avatar and ranking).

Ecogamification can make a positive impact on Tourism. With this in mind, the present study aims to examine specific stakeholders – those positioned at the upstream side of gamification process – and their perspectives concerning not only the benefits, but also the challenges of (eco)gamification.

The study follows a qualitative-exploratory approach and bases its results on the analysis of 10 in-depth interviews conducted with buyers and providers from the emerging Portuguese tourism and tech markets.

Results shed light on key benefits of ecogamification, including its potential to promote “green” behaviour, transmit complex information through entertainment, reward users for good practices, improve engagement and help avoiding overtourism. Simultaneously, there are important challenges to overcome, including the lack of investment, resistance to new technologies, low eco-consciousness of tourists and distraction from issues that matter. Further, findings show that ecogamification takes on different and specific roles for buyers and providers.

The research limitations are mainly related to the sample size.

An effective ecogamification process depends on the integration of the supply and demand sides and, at the same time, on the responsibility of different stakeholders (providers, buyers, players) across the value chain, through a broad logic of B2B2C.

This study contributes towards a better understanding of ecogamification in tourism, through the eyes of buyers and providers and also provides insights regarding the role of these specific stakeholders and the relationship between them.

This paper aims to exemplify the use of project management tools in the scheduling of aircraft maintenance activities. This process is known as maintenance, repair and overhaul and it has gained importance within the aeronautical sector due to its expected growth in the coming years; however, it also faces increasing competitiveness in its market. This fact gives rise to the need of acting in maintenance management and seeking lower costs while maintaining the quality of the service provided. The purpose of this paper is to propose the structuring of a procedure that aims to reduce the total maintenance time (downtime) and guarantee the delivery of the aircraft on time.

The paper, through a case study at a Brazilian aircraft maintenance center, used critical path method and critical chain project management, the latter being derived from the theory of constraints, with the purpose of analyzing resources systematically and synchronizing the activities in the precedence network.

As a result, it is shown that downtime can be reduced from 11 to 5 days and improvements are proposed to achieve greater market competitiveness.

This paper demonstrates the competitive advantage that resulted from the application of project management tools in the aircraft maintenance planning and execution.

The purpose of this study is to investigate the chemical and microbiological quality of biscuits and bread through the partial substitution of the wheat flour.

Completely randomized experiment with four treatments and nine replications was used in this study. The quality of biscuits and bread formulations was monitored by chemical parameters (moisture, ashes, protein, lipids, pH, water activity, acidity and carbohydrates) and microbiological parameters (coliforms at 35 and 45ºC, coagulase positive Staphylococcus and Salmonella sp.).

The formulation of biscuits containing 25, 50 and 75% of cassava flour and formulation of bread containing 10, 20 and 30% of cassava flour had higher carbohydrate content compared to the control formulation (p = 0.014). This was associated with the incorporation of cassava flour, which is an excellent producer of carbohydrates compared to other cereals. All formulations showed values <3 for coliforms at 35 and 45ºC and coagulase positive Staphylococci, as well as an absence for Salmonella sp.

The present attempt was made to formulate biscuits and bread with a reduction in wheat flour and the addition of manioc flour, with the objective of reaching products with higher carbohydrate content and low gluten content, to improve the nutritional level and commercial value of these products.

The “moral panic” generated by public response to teenage mothering marginalizes the experiences of young women as mothers, with adolescent pregnancy viewed as catastrophic for young women, their families, and society. In this analysis, focused on the experience of a group of teen women from the city of São Paulo, Brazil, the author explores how the integration of a maternal identity, shaped by Brazilian norms of “good motherhood,” with previously existing identities might lead to new aspirations and ambitions for the future or to hopelessness and despair.

Visions of the future were shaped by individual women’s structural circumstances and fell into four rough groups. Well-established adult women expressed their maternal identity through personal ambition, revealing confidence in their ability to provide “the best” for their children. Some adolescent mothers were fortunate enough to be buffered by family resources so that optimistic objectives for the future that pre-dated the pregnancy remained fairly attainable and were compatible with a “good mother” identity. For teens from less well-off families, motherhood resulted in a new-found determination to succeed in school and work, in line with ideals of Brazilian “good mothering” that focus on working hard to benefit one’s children. Women from the poorest households could or would not conjure a vision of the future, faced with the overwhelming challenges of their circumstances. The detailed, longitudinal qualitative data analyzed here reveal how the construction of maternal identity and visions of the future among adolescent mothers are shaped by the embodied experience of motherhood and pre-existing structural forces.

This paper aims to evaluate the profile of food truck consumers at gourmet events, identifying their food preferences and opinions about the provision of safe food by this segment.

A total of 750 food truck customers in the city of Curitiba, Brazil, participated in the study. The survey investigated the socio-economic profile of the consumers, the frequency of their food consumption, the criteria for their choice of food trucks, their mean spending value, the method of payment used and the opinion of consumers about food cost and food truck hygiene conditions.

Most consumers were female (62.7 per cent), students (31.3 per cent) and with an average age of 29 ± 10 years. Many customers preferred the consumption of salty foods (84.0 per cent), mainly burgers and kabobs. The consumers reported spending between $6.32 and $9.03 during the events, and men spent more money than women (p = 0.000). Both thought that good conditions of hygiene (81.9 per cent), food presentation (46.9 per cent) and service (48.0 per cent) were more important than the product price (19.3 per cent). Consumers thought that the food trucks had an adequate structure (73.5 per cent) and the food handlers (74.4 per cent) had good conditions of hygiene, ensuring the safety of the food sold.

On account of the convenience sampling in an urban environment, the data cannot be generalized to the entire population of the municipality and to other regions.

There are few studies with food trucks consumers in Brazil, to this writing the largest sample ever used for this type of research in this country. The results were designed to be used by professionals working in the area.

An efficient and adequate environmental monitoring plan is essential to any integrated coastal zone management (ICZM) program. The purpose of this paper is to apply an environmental diagnostic study to a coastal lagoon using anthropogenic markers as a decision support tool to aid the development of coastal environmental management policies.

Specifically, environmental status and anthropogenic sources were determined as part of a coastal environmental management plan; a study of human occupation and use was conducted to determine the predominant human activities around the lagoon; an environmental diagnostic study was conducted to determine the occurrence, levels and distribution of markers; and the results of the environmental diagnostic study were compared to indicators stipulated in Brazilian legislation.

Land use study revealed both urban and rural activities around the lagoon, as evidenced by the existence of residences, restaurants as well as poultry and livestock activities. The environmental diagnostic study revealed the input of human sewage (treated and raw) and runoff from animal husbandry activities.

The information produced using anthropogenic markers showed the influence of less studied rural activities, such as livestock and poultry farming, thereby providing a more reliable environmental status compared to the use of classic indicators employed in laws issued by international and Brazilian agencies.

The present results show that classic indicators used by environmental agencies are insufficient for an accurate diagnosis of coastal zones with multiple anthropogenic activities. Thus, the modernization of the environmental monitoring plan of the ICZM program is urgently needed for a more accurate assessment of coastal environments.
