Abstract
Purpose
This chapter examines changes in smallholder agriculture in terms of processes of de-agrarianization in a rapidly changing regional economy of Costa Rica long characterized by small-scale commercial coffee farming.
Methodology
The study is based on multiple periods (1990–1991, 1993, 2006, 2010–2012) of ethnographic research on household economic strategies among farming families in two districts in the canton of Pérez Zeledón, Costa Rica.
Findings
Though occupational multiplicity and non-farm-based livelihoods are on the rise, smallholder agriculture continues to play a substantial role in the livelihood strategies of both young and old and in the regional economy, not in spite of these trends, but because an expanding business sector and an increase in non-farm employment opportunities are creating a demand for agricultural produce and providing new opportunities for smallholders to diversify agricultural production, stabilize their incomes and maintain a significant presence in the regional economy. Specific historic conditions and state policies have been important factors in shaping rural economic change, livelihood strategies and smallholder agriculture in this region.
Research limitations
Sample sizes are relatively small and some data on children’s economic activities were obtained second hand from siblings and/or parents.
Implications
This research has implications for policy makers, planners and social activists interested in agrarian change.
Originality/value
This research provides an important longitudinal lens on the economic strategies of farming households, processes of de-agrarianization and the persistence of small-scale family farmers in today’s world.

Abstract
This study examines network coopetition strategies to promote the spatial distribution of tourists and their importance for Destination Management Organisations (DMOs). Geotagged photos from the municipality of Porto, Portugal (n = 152,312) uploaded to the Flickr social network between 2010 and 2022 were utilised, and thematic maps were produced using geographic information systems (GISs). Residents and visitors were identified and separated, employing a heuristic approach with a five-day threshold between the first and last photo of each user. The findings indicate an uneven distribution of tourists within the destination, with a notable concentration of accommodation, attractions and visitors in the historic centre. The establishment of a coopetition network could contribute to the dispersion of activity.

Abstract
Purpose
This paper aims to present a fast and effective approach to tackle complex fluid structure interaction problems that are relevant for the aeronautical design.
Design/methodology/approach
High fidelity computer-aided engineering models (computational fluid dynamics [CFD] and computational structural mechanics) are coupled by embedding modal shapes into the CFD solver using RBF mesh morphing.
Findings
The theoretical framework is first explained and its use is then demonstrated with a review of applications including both steady and unsteady cases. Different flow and structural solvers are considered to showcase the portability of the concept.
Practical implications
The method is flexible and can be used for the simulation of complex scenarios, including components vibrations induced by external devices, as in the case of flapping wings.
Originality/value
The computation mesh of the CFD model becomes parametric with respect to the modal shape and, so, capable to self-adapt to the loads exerted by the surrounding fluid both for steady and transient numerical studies.

Abstract
Purpose
Focusing on small- and medium-sized enterprises (SMEs), which are characterized by resource restrictions, this paper aims to explore consumer segment profiles by considering demographic, personality and creativity traits to determine whether consumers with different profiles exhibit distinct affective reactions to different logo design types (organic, cultural and abstract).
Design/methodology/approach
This exploratory study incorporates recent methodological developments, such as the novel response style correction method, to account for response style effects in evaluations of affect toward logo design. In separate analyses, respondents are segmented according to response style–corrected logo affect and personality and creativity items. The segmentation analysis relies on reduced k-means, a joint dimension and cluster analysis method, which accounts for dependencies between items while maximizing between-cluster variability. A total of 866 respondents from the Iberian Peninsula (Portugal: n = 543; Spain: n = 323) participated.
Findings
Based on a study using unknown logos (proxy for lower levels of budget communication, characteristics of SMEs), results reveal that there are three segments of consumers based on their affective response toward logo design: logo design insensitives, cultural logo dislikers and organic logo lovers. These segments are associated with different personality traits, creativity and biological sex (although biological sex is not a discriminant variable).
Research limitations/implications
The decision not to control logos by color, to increase external validity, could limit the study’s internal validity if this aspect interacts with relevant study variables. Nevertheless, the empirical evidence can be used to further test associations between consumer profiles and responses to logo design.
Practical implications
Findings highlight the relevance of considering complex profile segments, combining demographics, psychographics and creativity to predict affective consumer responses to brand logo design. This research provides guidelines for SMEs when choosing or modifying their logo design to appeal to different consumer segments.
Originality/value
This study provides managers of SMEs (less present nowadays in empirical studies) with evidence suggesting that complex customer profiles help to understand differences in affective responses to natural logo designs. Furthermore, it relies on the use of a novel methodological development that improves the accuracy of the exploratory study developed.

Abstract
Purpose
The purpose of this paper is to optimize the performance of an incinerator plant in terms of NO emissions and temperature of particles 2 s after the last air injection, which must be above 850°C as established from the Directive 2000/76/EC of the European Parliament and of the Council – December 4, 2000 on dioxins formation in waste incineration plants.
Design/methodology/approach
Investigation is made by coupling proper models developed within three commercial software environments: FLUENT, to reproduce the thermodynamic field inside the combustion chamber of the incinerator plant taken into account, MATLAB, to evaluate the position and temperatures of the particles 2 s after the last air injection, MODEFRONTIER, to change both the secondary air mass flow rate and the equivalent heat transfer coefficient of the refractory walls to fulfill the conflicting objectives of reducing the NO formation and increasing the mean gases temperature as required by the Directive.
Findings
The investigations suggest that it is possible to create the conditions allowing the reduction of NO emissions and the fulfilment of the European limits. In particular, the obtained results suggest that increasing the overall mass flow rate of the secondary air and using a different refractory material on the walls, the environmental performance of the incinerator plant can be improved.
Research limitations/implications
Many other parameters could be optimized and, at the same time, more detailed models could be used for the Computational Fluid Dynamics simulations. Moreover, also the energy generated at the plant would need a better investigation in order to understand if optimal conditions can be really achieved.
Originality/value
The work covers new aspects of Waste-to-Energy (WtE) systems, since it deals with an optimization study of plant design and operating parameters. This kind of investigation allows not only to improve already existing technologies for WtE systems, but also to develop new ones.

Abstract
Purpose
This study aims to examine differences in regret between individuals with high vs low self-esteem that follows from negative appraisals for unsuccessful consumer decisions that are either congruent or not with perceived norms. This study also tested the mediating role of decision responsibility and the ability of psychological repair work in regulating regret.
Design/methodology/approach
Hypotheses were tested through four experimental studies using student and international panel samples across different consumer decision scenarios to generalize the findings of the study.
Findings
This study shows that high self-esteem individuals regret less a bad decision when it is congruent (normal) than when it is incongruent (abnormal) with the prevalent norms, while lower self-esteem individuals tend to regret equally both normal and abnormal decisions. This study further shows that this effect is driven by internal responsibility attributions. Finally, the results also suggest that high self-esteem people are more efficient than low self-esteem people in regulating regret, but only when the decision is abnormal.
Originality/value
The present research has important contributions to both regret and self-esteem literature. First, this study explored the role of self-esteem on regret, an individual variable that has been studied relatively little in regret literature. Second, this study has shown, consistent with recent findings, that decision congruence with the norms is a more suitable predictor of regret than whether the decision involves action or inaction. Finally, this study showed that stimulating individuals to self-enhance by engaging in psychological repair work led individuals to regulate regret, consistent with regret regulation theory.

Abstract
Purpose
This paper aims to study and explore the activities and the use of institutional network resources by industrial business associations (IBAs) to support and facilitate internationalisation processes of small- and medium-sized enterprises (SMEs). Other goals are to understand the internationalisation follow-up process and the future vision of IBAs to improve this internationalisation support.
Design/methodology/approach
Based on empirical evidence and following an abductive approach, this paper presents a qualitative exploratory field research, providing insights from interviews performed with 20 IBAs based in Portugal.
Findings
The findings suggest that the current institutional network support to internationalisation is mainly provided through promotional activities; counselling, training and technical and legal support; information sharing; and cooperation with other institutional entities. Each support category is explored and explained and a new conceptual model is developed to represent these findings. Regarding the internationalisation follow-up, IBAs provide a continuous support for the international operations by using some instruments and mechanisms to assist SMEs after an internationalisation initiative. Finally, collaboration and the use of new information technology are the main aspects to improve IBAs’ support in a near future.
Research limitations/implications
The qualitative methodological approach adopted in this work can imply a larger difficulty to obtain a generalisation of the findings. Another limitation is that the participating IBAs are based in only one country.
Practical implications
Findings can help SMEs to understand the functioning and the benefits of using the institutional network resources of IBAs in overcoming their lack of resources to operate in international markets. IBAs can also understand their current position in terms of internationalisation support and think about new ways for improving this support.
Originality/value
This paper contributes to a better understanding of the influence of institutional networks in SME internationalisation by exploring the specific role of one of the institutional actors rather than focusing on the institutional network as a whole. Therefore, this study details the current activities and uncovers other types of support provided by IBAs that are not based on export promotion programmes. New knowledge is also obtained about the specific information content, information sources and means and channels of information sharing used by IBAs for supporting SME internationalisation.

Abstract
Purpose
The purpose of this paper is to describe six recovery-oriented peer support experiences and strategies implemented in different regions of Brazil in the past 12 years, and explore challenges to their development and potential for empowerment and citizenship.
Design/methodology/approach
In this paper, a group of stakeholders in mental health services involving people with lived experience of severe mental illness describe their experiences with services of peer support. These were all conducted in Brazil and in partnership with the International Recovery and Citizenship Collective (IRCC) and The Yale Program for Recovery and Community Health. The authors met monthly to exchange experiences, studies and practices, and six experiences were selected, described, analyzed and compared. A discussion of these experiences, their challenges, impact and potential followed.
Findings
The explored experiences emphasize that peer support, lived experience leadership and advocacy are feasible in the Brazilian mental health system and can help advance the Brazilian Psychiatric Reform.
Research limitations/implications
This paper is limited to the experience of researchers already engaged in peer support work in six cities in Brazil. Although they represent several different regions in Brazil, there are areas it has not reached. Further research should address and provide a broader view of peer support and recovery strategies spreading in the country.
Social implications
These experiences demonstrate the feasibility and acceptability of the recovering citizenship approach to reduce stigma, promote empowerment, autonomy, activism and advocacy, and increase a sense of belonging for those in recovery and marginalized by society. The Brazilian psychiatric reform can benefit from including peer supporters as mental health treatment providers.
Originality/value
This paper provides a novel view of the state of the art of peer support initiatives in Brazil and can inspire individuals, government and communities as they see and understand the breadth, depth and meanings of these peer support experiences.
