Abstract
Purpose
This paper aims to present the results of an extensive experimental programme on the fire behaviour of timber beam-to-column shear connections, loaded perpendicularly to the grain.
Design/methodology/approach
The experimental programme comprised tests at normal temperature and loaded fire resistance tests on beam-to-column connections in shear. Twenty-four full-scale tests at normal temperature were performed covering nine different connection typologies, and 19 loaded fire resistance tests were conducted including 11 connections typologies.
Findings
The results of the fire resistance tests show that the tested typologies of steel-to-timber dowelled connections reached more than 30 and even 60 minutes of fire resistance. However, aspects such as a wider gap between the beam and the column, reduced dowel spacing, and the presence of reinforcement with self-drilling screws all have a negative influence on the fire resistance.
Originality/value
The experimental programme addressed the fire behaviour of timber beam-to-column shear connections loaded perpendicularly to the grain in a systematic way testing a wide range of common connection typologies significantly enlarging their experimental background.

Abstract
Purpose
This paper aims to investigate factors that induce entrepreneurial orientation (EO), i.e. what influences the manifestation of its fundamental attributes (innovativeness, proactiveness and risk-taking).
Design/methodology/approach
This study focuses on religious entrepreneurship in an emerging economy, employing a single case study approach. A total of 17 shepherd-entrepreneurs and 4 parishioners were interviewed.
Findings
The results suggest that two key driving factors influence religious entrepreneurs’ EO: the search for the discovery of opportunity (a finding that strengthens current literature); and both the search for the creation of opportunity and overcoming challenges associated with the need for survival.
Practical implications
This paper allows entrepreneurs to understand better the factors and motivations that affect their entrepreneurial behavior. It is particularly relevant to entrepreneurs embedded in emerging and developing countries, in which the interchange between opportunity and need contexts is apparent. Further, this paper sheds light on significant dimensions for entrepreneurs’ education and training programs. It also suggests elements capable of bolstering public policies.
Originality/value
The contributions of this paper are fourfold: it supports an integrative view of creation and discovery theories; it reinforces the alternating character of entrepreneurial motivations; it expands the literature by arguing that creating opportunity and the need for survival also influence entrepreneurs' innovativeness, proactivity and risk-taking; and it stresses the neo-Pentecostal shepherds' entrepreneurial propensity.

Abstract
Purpose
The purpose of this paper is to use Amazon River shrimp meal and cassava flour as the raw materials for the production of an extruded product. Both these raw materials are highly consumed foods in the northern region of Brazil, but are not processed industrially, only being used for local consumption and there is little in the literature concerning their use.
Design/methodology/approach
The study was carried out using a full 23 factorial central composite rotational experimental design with three independent variables, which were shrimp meal; feed moisture content and temperature, with four replicates at the central point and six axial points. The dependent variables were: expansion index (EI), bulk density (BD) and specific length (SL). The principal component analysis (PCA) was applied for the sensory analysis.
Findings
Almost all the parameters studied had a significant influence (p<0.10) on the responses analysed. The product was well accepted by 78.11 per cent of the volunteers. Increases in the shrimp meal and feed moisture contents strongly influenced the physical analyses (EI, BD and SL) of the extruded product. In the application of the PCA for the sensory analysis, the influence of the variables aroma, appearance and purchase intention corresponded to PC1, and that of the variables flavour, texture, global acceptance and colour to PC2.
Social implications
The development of a product based on animal protein which is more available than common snacks, as a way of reducing the negative environmental impact caused by the disposal of Macrobrachium amazonicum, which is considered as accompanying fauna to artisan fishery.
Originality/value
The originality of this paper lies in the quest for the development and/or application of technologies that allow for the use of raw materials from the Amazon as a way of aggregating value to the existing wealth of this region.

Abstract
Purpose
This paper aims to identify the impacts of wire and arc additive manufacturing (WAAM) technology on the green supply chain management (GSCM) performance. Also, it intends to identify the most essential WAAM capabilities.
Design/methodology/approach
An exploratory case study related to a metallurgical company using WAAM technology to repair metallic components was developed. A research framework to identify WAAM production capabilities and the different GSCM performance criteria was proposed based on the current state of the art. Primary qualitative data provided evidence for developing seven propositions relating WAAM capabilities to GSCM performance.
Findings
The paper provides empirical evidence relating to how WAAM production capabilities impact the different performance criteria of the GSCM performance. The results show that “relative advantage” and “supply-side benefits” are critical capabilities developed through WAAM. Furthermore, most of the capabilities regarding “relative advantage” and “supply-side benefits” promote a higher GSCM performance.
Research limitations/implications
This research was carried out using a single case study research design and using qualitative data. Thus, future works are encouraged to test the propositions empirically using quantitative methodologies.
Practical implications
The case study findings support that most WAAM production capabilities promote a higher GSCM performance. Managers could use this research to understand the capabilities developed by this fusion-based additive manufacturing (AM), become aware of the implications of new technology adoption on the supply chain environmental externalities, and develop new business models based on the WAAM capabilities.
Originality/value
This research contributes to expanding the state-of-the art related to WAAM technology by evidencing the relationship between adopting this fusion-based AM technology and green supply chain practices. Also, it provides a set of seven propositions that could be used to theorise the impacts of WAAM adoption on the GSCM performance.

Abstract
Purpose
Because women ' s status in Latin American countries appears comparable to their status in organizations of more economically advanced nations, this paper probes the mystery of how and why these women fare relatively well in their careers, given that socioeconomic and cultural factors could limit their possibilities of achieving higher management positions. The paper aims to discuss these issues.
Design/methodology/approach
Exploratory study of 162 Latin American women who demonstrated exceptional success by attaining first and second level positions in private organizations. They responded to a semi-structured interview of 49 closed-ended questions about career challenges and barriers, leadership style, ambition, personal goals and work-life balance, plus two open-ended questions about men and women ' s leadership differences and how they understand their success.
Findings
Interviewees disagreed on issues of discrimination, recognized few serious professional career barriers and regarded work-life balance as their main challenge. They understood their success in terms of individual factors such as personality characteristics, performance and results, and their own leadership traits. Most admitted that machismo limits women ' s access to upper level positions. They recognized their ambition to attain power positions mainly for personal satisfaction, and their main goal was personal development and fulfilment.
Research limitations/implications
Given the sample size per country, future research could include a more representative and large sample or concentrate on one country per region to establish relationships between women ' s personal characteristics and organizations ' sector, or challenges faced and leadership style. Also family-owned companies as well as women entrepreneurs could contribute knowledge about women ' s leadership in these countries. Studying only national companies, a more neatly description of local culture and gender awareness in its organizational practices that hinder or promote women ' s leadership and participation in decision-making positions may be obtained. Transcultural studies that compare women ' s rise and upper management performance in countries where support from domestic help and extended family as well as cultural values are very different, could permit to understand more fully what it takes to reach top management positions and the weight that these particular cultural conditions have.
Originality/value
This study is unique in shedding light on a multinational sample of Latin American female executives and their perceptions of their success, leadership style and barriers and challenges faced.

Abstract
Purpose
The purpose of this study sought to identify the main themes linked with wine hotel experiences, based on tourists’ narratives shared online, and to investigate whether these narratives vary according to traveler type.
Design/methodology/approach
Content analysis was carried out on 4,114 online reviews of 52 wine hotels located in 27 wine regions across 11 nations in both the Old and New World.
Findings
The analysis of these web reviews revealed that narratives can be grouped under 11 themes organized into 7 main dimensions as follows: wine, lodging (i.e. hotel, area and room), food service (i.e. restaurant and breakfast), scenery (i.e. views and vineyards), staff, transportation and recommendation. The main narratives vary according to traveler type.
Practical implications
Improving the present understanding of wine tourists’ experiences should help wine hotel managers find new approaches to enhancing visitors’ satisfaction. As the dimensions of wine tourism experiences shared online vary according to traveler type, wine managers can design their offer to target families, couples, friends, solo and corporate clients.
Originality/value
Prior research has identified the need for market segmentation in the wine tourism industry. This research addresses this need by specifying the wine tourism experience according to traveler type. The breadth of the data, and the method of using travelers’ own testimony as opposed to more common surveying are additional contributions for both academics and managers.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
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.
Originality/value
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.
