This study looks at how visitor experience in gastronomic events impacts subsequent cross-purchases of local food products and specifically explores how attending food rituals enhances the perceived authenticity of the event, which in turn influences the culinary experience value (both learning and hedonic) for tourists. The study also considers two moderating variables: geographical distance and visitor ethnocentrism. The empirical research focuses on the centuries-old celebration of a gastronomic event in which participants taste typical dishes, with the possibility of previously attending a traditional ritual which involves a demon- stration of pork cutting and preparation methods. Findings indicate that attending the ritual increases the perception of authenticity, which positively affects the perceived value of the experience. Notably, only the learning value significantly impacts the subsequent cross-purchase of local products. Furthermore, authenticity affects cross-purchasing behaviour, particularly among visitors with higher levels of ethnocentrism or those travelling from further afield.

Users frequently spend longer than anticipated browsing online stores, resulting in online shopping stickiness, i. e., the intention to prolong navigation time within a browsing session, irrespective of the number of websites visited. This research investigates how exploration behaviours and browsing objectives impact stickiness during online shopping sessions. Specifically, the work analyses what influence exploration modes (specific vs. diver- sive) and goals (purchase-oriented vs. search-oriented) have on user stickiness, with perceived enjoyment and satiation acting as mediating factors. Using two experiments in the context of online clothing shopping and a field study, this work emphasizes the role of situational browsing elements in shaping stickiness behaviour. The findings enrich e-commerce literature by shifting the perspective from external factors (e.g., product or site attributes) to in-store exploration behaviours. This research offers valuable insights for e-commerce platforms that aim to optimize website interfaces to improve consumer experience and boost consumer retention, such as aligning navigation and content with user intentions and utilizing cross-category suggestions

Qualitative project risk assessment is standard practice in project management and involves prioritising risks using a probability and impact matrix. Due to the shortcomings of using this tool for risk prioritisation (poor resolution, errors, suboptimal resource allocation or ambiguous inputs and outputs, among others), we propose a quantitative prioritisation of project risks in this article, analysing the impact of each risk on the project’s duration and cost objectives.

La gestión de la complejidad de los proyectos ha suscitado gran atención dentro de la academia, abordándose el tema desde distintas perspectivas que han dado lugar a distintos modelos de complejidad. En este articulo abordamos la complejidad en proyectos desde el enfoque del pensamiento sistémico, una disciplina que tiene precisamente como centro de estudio la complejidad de los fenómenos sociales, económicos, tecnológicos, etc. En concreto, analizamos el caso práctico de un proyecto realizado por una PYME industrial situada en Castilla y León (España). Se realizaron entrevistas antes y después del proyecto a todos los miembros del equipo de proyecto, así como al personal de alta dirección de la empresa. Fruto de estas entrevistas, analizamos como los modelos mentales (individuales y colectivos) afectan a la complejidad percibida del proyecto, que a su vez condiciona las decisiones tomadas durante su ciclo de vida. Los resultados de estas decisiones, a su vez modifican la complejidad percibida y los modelos mentales que influirán en futuros proyectos (aprendizaje). Los resultados de la investigación sugieren que el enfoque sistémico permite explicar situaciones en las que las decisiones de los directores/as de proyectos tienen efectos distintos a los esperados.

Los prototipos constituyen elementos fundamentales en multitud de proyectos, siendo en muchas ocasiones necesarios para la validación del producto o servicio objeto del proyecto, entre otras muchas razones. Al ser objetos generalmente singulares, el equipo de dirección de proyecto frecuentemente no dispone de los medios para producir estos prototipos internamente, por lo que es frecuente acudir a proveedores especializados. Al respecto, es bien conocida la dificultad para gestionar los prototipos ya que son elementos extraños en las cadenas de suministro establecidas, suponiendo un coste importante para el proyecto que puede llegar a penalizar su rentabilidad y cuya gestión supone una gran cantidad de recursos y energía al equipo de proyecto. Es por ello que el objeto de esta comunicación es la de introducir la tecnología de blockchain como propuesta en la gestión de los prototipos en el ámbito de un proyecto, asegurando de esta manera una gestión más eficaz al asegurar dicha tecnología una completa trazabilidad, así como una reducción de los costes de transacción.

The growing need to develop, transform, and integrate new knowledge into economic processes has driven a notable increase in research, development, and innovation (R&D&i) projects. These projects face significant uncertainty, as outcomes often differ from initial expectations. They also aim for transformative impacts across diverse sectors and require collaboration among industry, academia, government, and civil society stakeholders. Aligning these varied interests with project objectives can be challenging, frequently limiting the scalability of results in socio-economic contexts. Consequently, effective project management methodologies capable of handling such complexities are increasingly crucial. This study presents a comprehensive theoretical review of methodological frameworks for managing R&D&i projects. It examines predictive and adaptive approaches to identify attributes best suited for project lifecycle phases. The primary goal is determining which phases benefit from traditional management techniques and which require agile practices to address uncertainty and change. Based on this analysis, the study proposes an innovative hybrid framework integrating best practices from both approaches, enhancing operational efficiency and impact.

In this paper, we show that correlations between the durations of project activities can change the project’s total variance and some risk sensitivity indexes such as the Cruciality (CrI) and SSI (Schedule Sensitivity Index). These results are relevant in project risk management as correlations may change risk response strategies, and monitoring efforts should focus on other activities. We performed Monte Carlo simulations using different network topologies with different characteristics.

Virtual reality (VR) is reshaping tourism as museums increasingly adopt it to create immersive visitor experi- ences. While presence is key to VR effectiveness, little is known about how interaction modes affect it. This study examines the impact of two elements guidance and spatial mobility on perceived presence in virtual museum visits. It also explores the psychological mechanisms involved and identifies autonomy as a positive driver and satiation as a limiting factor. Results show that guidance enhances presence although it slightly reduces au- tonomy, while spatial mobility has less of an effect. In turn, presence boosts perceived entertainment and informativeness and positively influences attitudes toward the destination and visit intention. This research helps to understand how interaction design in immersive environments shapes user experience and behaviour. It offers theoretical insights on presence drivers as well as practical implications for creating more effective, satisfying, and wellbeing-oriented VR experiences in tourism

This paper explores how blockchain technology can accelerate negotiations within industrial supply chains, focusing on prototype management in the automotive sector. Through a real case study involving a car manufacturer and a tier 1 supplier, we analyse the complex workflow from prototype request initiation to purchase order issuance. The study identifies critical bottlenecks that hinder process efficiency, such as communication delays and prolonged negotiations. By simulating blockchain-based transactions on the Ethereum platform, our analysis quantifies the costs associated with decentralised record-keeping and smart contract execution. The findings demonstrate that blockchain enhances transparency, traceability, and data integrity while reducing reliance on intermediaries and mitigating negotiation delays. Despite challenges such as cryptocurrency volatility and the need for operational adaptations, our results highlight blockchain’s potential to streamline supply chain interactions and lower overall transaction costs. This work contributes to the supply chain optimisation and digital transformation literature by providing empirical insights and practical guidelines for integrating blockchain solutions in complex industrial environments.

The purpose of this paper is to contribute to the advancement of knowledge on how to manage the perceived complexity by project participants. For this, we carried out a case study approach and we chose an R&D project carried out by an SME, which was partly co-financed by a public entity. We use a qualitative approach for our research. In addition, we conducted semi-structured interviews, at the beginning, and at the end, of the co-financed part of the project, using the Complexity Assessment Tool (CAT) as a scheme. The results showed the usefulness of the CAT to guide the responses to the perceived complexity and the use of social capital and human capital as a source that is used by the participants in the project to develop the responses. Our work extends knowledge about the importance of developing responses to complexity and the sources from which they arise.

Games with endogenous separation are repeated games where players have the option to leave their current partnership and keep on playing in a newly- formed partnership. Arguably, most repeated interactions in real life fall into this category. We present a general framework to analyze equilibria in games with endogenous separation, extending concepts from evolutionary game the- ory, and with a focus on neutrally stable strategies, i.e., stable strategies that are resistant to direct invasion by any alternative strategy. We introduce path- protecting strategies, which play a similar role to trigger strategies in standard (fixed-partnership) repeated games, and we provide a constructive proof of their existence. We also present a Folk Theorem for path-protecting strategies in these games.

Combinatorial double auctions provide an efficient mechanism for resource allocation, maximizing social welfare without requiring private information from participants. However, depending on specific auction conditions, the number of rounds required for convergence can be significantly high. In this work, we extend a previously developed DEVS-based auction model to study the dynamics of social welfare evolution throughout the auction process. While the original model identifies the allocation that maximizes social welfare, our extension enables tracking the proportion of the optimal social welfare achieved at each round. This analysis provides insights into the auction's convergence behavior and serves as the foundation for developing an approach that helps auctioneers select appropriate parameters to achieve a sufficiently good outcome within a reasonable number of rounds in real-world scenarios.

This paper discusses a prominent way in which social simulations can contribute (and have contributed) to the advance of science; namely, by refuting some of our incorrect beliefs about how the real world works. More precisely, social simulations can produce counter-examples that reveal something is wrong in a prevailing scientific assumption. Indeed, here we argue that this is a role that many well-known social simulation models have played, and it may be one of the main reasons why such well-known models have become so popular. To test this hypothesis, here we examine several popular models in the social simulation literature and we find that all these models are most naturally interpreted as providers of compelling and reproducible (computer-generated) evidence that refuted some assumption or belief in a prevailing theory. By refuting prevailing theories, these models have greatly advanced science and, in some cases, have even opened a new field of research.

University business incubators (UBIs) are born as tools of the academic world to market research results, for the transfer of technology and to promote entrepreneurial spirit. In these contexts, the exchange of knowledge among entrepreneurs can be a key variable for the development and success of their businesses. This paper aims to analyse the characteristics of entrepreneurs’ resources and the institutional logic that prevails in the incubator as determinants of the exchange of knowledge, and the authors examine the results in terms of entrepreneurial commitment and the generation of innovations.

Although knowledge integration has been deemed relevant for the development and survival of family firms, prior studies suggest that the lack of skills to combine and transfer incumbent family members' knowledge within the family may hinder family firms' organizational effectiveness. Knowledge integration, in this context, might depend on family involvement in ownership, management and governance, and family essence, considering the emotional and relational aspects of the influence the family exerts on the business. Relying on knowledge-based view and dynamic capability perspectives, we propose a model suggesting that knowledge integration intervenes in the relationship between familiness and organizational effectiveness. Our hypotheses are tested on a sample of 102 private Spanish family businesses. The results reveal that familiness is beneficial for knowledge integration, enhancing family firms' organizational effectiveness. Our study provides practical implications for family business owners and managers, and opportunities for further research.
