Title: Integrating Resilience and Sustainability Paradigms in Vaccine Supply Chain Management: A Multi-Objective Simulation/Optimization Approach Authors: Gomes, Luís Pedro; Ferreira, Paulo; Almeida, Dora Editors: Galdames, I.S.; Vázquez-Justo, E.; Abreu, A.; Carvalho, J.V. Abstract: Vaccination is crucial for human health, and the success of vaccination programs depends not only on the vaccines themselves but also on the strength of the supporting supply chain and logistical systems. The World Health Organization emphasizes the importance of sustainability and resilience in vaccine supply chains, as outlined in the Immunization Agenda 2030. This paper aims to illustrate how multi-objective simulation/optimization can assist decision-makers in integrating sustainability and resilience concepts in vaccine supply chain management, based on the Paradox Theory. The technique was applied to the operational management of a vaccination point in the Central Alentejo region, resulting in nine non- dominated solutions. This approach enables decision-makers to make data-based decisions and gain insights into the potential outcomes before finalizing their choices. Our find ings demonstrate that multi-objective simulation/optimization provides valuable insights, allowing decision-makers to consider a more comprehensive “both-and” approach instead of singular choices.

Title: The influence of institutional and in-group collectivism practices on next-generation engagement in the family business Authors: Torres, Pedro; Augusto, Mário; Quaresma, Rui Abstract: Purpose This research aims to investigate the influence of country culture on the next generation's intention to become managerial leaders of the family business, focussing on institutional and in-group collectivism practices. The authors investigate not only the direct effect of these collectivism practices on next-generation engagement, but also the extent to which institutional and/or in-group collectivism moderate the relationship between parental support and next-generation engagement and the extent to which institutional and/or in-group collectivism moderate the relationship between self-efficacy and next-generation engagement. Design/methodology/approach Using cross-national data from the Global University Entrepreneurial Spirit Students' Survey (GUESSS) and the Global Leadership and Organisational Behaviour Effectiveness (GLOBE), hierarchical linear modelling (HLM) is employed to test the hypotheses using a sample of 33,390 observations collected in 20 countries. Findings The main findings show that both institutional and in-group collectivism practices may increase next-generation engagement levels. Furthermore, these cultural practices can amplify the relationship between family business self-efficacy and next-generation engagement. However, institutional collectivism can slightly reduce the positive effect of parental support on family offspring's intention to become leaders of the family business. The results also reveal that parental support has a stronger direct effect on next-generation engagement than family business self-efficacy. Originality/value This study examines the influence of cultural practices on next-generation engagement, focussing on collectivism practices. The study distinguishes between institutional collectivism and in-group collectivism. Unlike past research, a direct effect of parental support on next-generation engagement is considered. The study also uses a particular type of self-efficacy: family business self-efficacy. In addition, a multi-level method is employed, which is rarely used in this context.

Title: Information Ethics Among College Students – Selected Countries Analysis Authors: Marreiros, Cristina G.; Milos, Ulman; Quaresma, Rui; Xiong, Jason; Harris, Albert L. Abstract: Information ethics (IE) influences how people use and produce information and affects information services, information technology (IT), and professional practices. Lack of IE severely affects individuals, teams, organizations, or the community. This research bridges a gap in understanding IE perceptions and IE-declared behavior among different sociodemographic profiles in the global communicative space. We devised an extended version of the IT ethics survey to measure attitudes toward IE issues. We surveyed a sample of 1,648 college students in seven countries. We identified four clusters, uncovering groups of people with very high (Legalists), high (Moralists), fair (Pragmatists), and low (Anarchists) perceptions of the IE issues. Clusters allow the exploration of patterns in IE perceptions that would remain hidden at an individual level of analysis and can help to predict IE-related behavior. The findings imply that teachers should adapt IE curricula, and managers should customize the policies and interventions to these groups. Furthermore, managers should consider group behavior and account for factors that affect it in the corporate world, such as lower computer knowledge. International managers should be aware that certain groups behave more unethically with IT and are overrepresented in certain countries.

Title: What Drives Sustainable Development in Europe? A Panel and Fuzzy Analysis of Cohesion and Non-Cohesion Countries Authors: Almeida, Dora; Dionísio, Andreia; Ferreira, Paulo; Kamińska, Joanna A. Abstract: The European Union (EU) is highly committed to the 2030 Agenda. However, the EU countries’ structural heterogeneity and differ-ing stages of development complicate the efforts to achieve the Sustainable Development Goals (SDGs) and raise questions aboutwhether uniform policies can effectively address diverse needs. To analyze the determinants of the SDG Index score (SDG_IS),the EU-27 countries were considered over the 2012–2023 period, grouped into Cohesion and Non-Cohesion countries, and paneldata regression models and fuzzy-set qualitative comparative analysis (fsQCA) were applied as complementary approaches. Thepanel data regression results revealed a main decoupling: while in Cohesion countries, Gross Domestic Product per capita sig-nificantly drove SDG_IS attainment, it lost statistical significance in Non-Cohesion countries, where institutional transparencyand inequality reduction emerged as the main drivers. The fsQCA analysis revealed pronounced equifinality, identifying five dis-tinct pathways to high SDG_IS attainment in Cohesion countries and only two in Non-Cohesion countries. Overall, by revealingthat as countries develop, the determinants of sustainability may shift from material wealth accumulation to governance qual-ity and distributive justice and that the same level of SDG_attainment can be obtained through qualitatively different causalconfigurations, our findings challenge the paradigm of “one-size-fits-all” that underlies the current EU cohesion policy and pro-vide an empirical foundation for redesigning EU policies around differentiated, context-sensitive interventions: growth-orientedstrategies for Cohesion countries and governance-quality strategies for Non-Cohesion countries, aligned with smart specializationprinciples.
