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. 2026-04-30T23:00:00Z http://hdl.handle.net/10174/42287 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. 2023-07-12T23:00:00Z http://hdl.handle.net/10174/42280 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. 2024-01-27T00:00:00Z http://hdl.handle.net/10174/42274 Title: IT Ethics Perceptions and Behavior: An International Comparison Authors: Ulman, Milos; Marreiros, Cristina G.; Quaresma, Rui; Harris, Albert L. Abstract: The paper discusses differences in IT ethics perceptions and behavior of college students. The study is one of the few that examine multicultural differences in IT ethics on a convenience sample of 1,648 individuals from seven countries in three continents. We adopted an Ethics Decision-Making Model with Cultural Impacts and applied it on the examination of relations between IT ethics perceptions, behavior, nationality and culture operationalized through Hofstede’s scores. We collected data through an online questionnaire where respondents evaluated 21 scenarios describing various IT ethical issues in the form of a narrative, and seven items on individual’s behavior toward IT ethics issues. The individuals’ perceptions of IT ethics and their behavior differed significantly, and most of these differences were associated with nationality and culture. Associations between perceptions and behavior were also uncovered, which leads to the importance of understanding perceptions in order to change less ethical behavior regarding IT use. 2019-12-09T00:00:00Z
