- Co-creating a sustainability performance assessment tool for public sector organisationsPublication . Ramos, Tomás B.; Domingues, Ana Rita; Caeiro, Sandra; Cartaxo, Joana; Painho, Marco; Antunes, Paula; Santos, Rui; Videira, Nuno; Walker, Richard M.; Huisingh, DonaldOrganisations are increasingly being pushed to manage, assess and report their sustainability performance, including public sector organisations (PSO). Several approaches were developed to implement sustainability assessments at the organisation level. However, the majority are still for the private sector and are often not supported by active stakeholder involvement. Several PSO have adapted private-oriented models to assess their sustainability performance, which are often not adequate due to public administration, whose main mission is to provide public services. The present work aims at developing a conceptual framework to support PSO and to assess their sustainability performance. The proposed approach is supported by two sustainability performance assessment systems – Formal and Informal Sustainability Performance Assessment. The Formal Sustainability Performance Assessment system, which is the main focus of this paper, consists of a checklist of objectives and practices and a set of twenty-nine (29) performance indicators. An initial proposal was drawn from the literature review and then assessed through a participatory process involving practitioners and academics in semistructured interviews, questionnaire surveys and a collaborative workshop. The Portuguese central public administration was used as a case study. The developed checklist of objectives and practices and related performance indicators will allow PSO to assess and communicate complex information about organisational sustainability. Reference values support the normalization of indicators’ results, and consequently, the comparison of sustainability-related performance between PSO integrated into the context of the Portuguese central public administration. This research contributes to the debate on organisational sustainability assessment and communication, and the importance of selecting and developing sustainability indicators using co-creation processes with key stakeholders.
- Economic impact of healthcare cyber risksPublication . Brilhante, Maria de Fátima; Mendonça, Sandra; Pestana, Pedro Duarte; Rocha, Maria Luísa; Santos, RuiPurpose: The healthcare sector is a primary target for cybercriminals, with health data breaches ranking among the most critical threats. Despite stringent penalties imposed by the U.S. Department of Health and Human Services Office for Civil Rights (OCR), vulnerabilities still persist due to slow detection and ineffective data protection measures. On the other hand, as organizations are often reluctant to disclose security breaches for fear of reputational and market share losses, penalties can serve as a useful proxy for quantifying losses and insurance claims. Methods: This study analyzes fines and settlements (2008–2024) using the traditional lognormal, general extreme value (GEV) and other heavy-tailed statistical models, including the geo-max-stable loglogistic law, and also the mixture models hyperexponential and hyperloglogistic. Results: Mixture models, either the hyperexponential or the hyperloglogistic, deliver the best fit for OCR penalties, and for yearly maxima, the best fit is achieved with the GEV distribution. Regarding Attorneys General fines, the hyperexponential model is optimal, with the GEV model excelling again for their yearly maxima. Hence, mixture models effectively capture the dual nature of penalty data, comprising clusters of moderate and extreme values. However, yearly maxima align better with the GEV model. Conclusions: The findings suggest that while Panjer’s theory for aggregate claims suffices for moderate claims, it must be supplemented with strategies to address extreme cybercrime scenarios, ensuring insurers and reinsurers can manage severe losses effectively.
- Employee-driven sustainability performance assessment in public organisationsPublication . Coutinho, Vera; Domingues, Ana Rita; Caeiro, Sandra; Painho, Marco; Antunes, Paula; Santos, Rui; Videira, Nuno; Walker, Richard M.; Huisingh, Donald; Ramos, Tomás B.Organisations are increasingly adopting sustainability performance assessment tools. However, these formal organisational sustainability assessments are typically managed and prepared by technical staff. There is a lack of research on approaches that enable a stakeholder-driven performance assessment. This paper develops a framework of informal/complementary stakeholder-driven sustainability performance assessment, from the perspective of employee voluntary collaboration. The framework composes a checklist of questions covering the main sustainability domains: perceptions, individual practices, and voluntary monitoring indicators. In an exploratory case study in a public organisation, the checklist was evaluated by employees in a participatory workshop. The evaluation criteria of understanding and usefulness were rated more positively than reliability. This paper shows a novel way of integrating employee inputs for informal sustainability assessment and supports the importance of empowering public organisations, thereby increasing their understanding of sustainability management frameworks.

- Sci-Bi: an infodemic of disorientationPublication . Alvelos, Heitor; Barreto, Susana; Lima, Cláudia; Penedos-Santiago, Eliana; São Simão, Fátima; Pereira, Jorge; Carneiro, José; Dolbeth, Júlio; Fernandes, Marta; Martins, Nuno; Veiga, Pedro Alves da; Santos, Rui; Vieira, Sónia; RuiRecent years have seen the emergence of two particular challenges to scientific knowledge and application. In both instances, communication design may be underperforming in its potential for contribution: 1. The exponential rise of social media has potentiated an equally exponential range of phenomena such as fake news, pseudo-science and superstition; as seductive, de-centralised, continuously reconfiguring webs, their longevity and adaptability far surpass that of rigorous knowledge. 2. The pandemic and corresponding public policies (confinement and vaccination in particular) seem to have further eroded the already precarious, aforementioned scenario. A range of misinformation channels and content have reached significant sectors of the population, just as media portrayal of the health crisis was largely reduced to statistical extrapolations, and a largely hermetic, prescriptive discourse often lacking in accessibility. Despite current decreases in pandemic levels, issues of mistrust remain and will likely retain an impact in future instances, health-related or otherwise. The above issues have been addressed both through increased technological sophistication of digital tools, and the adoption of logical discourse; however, both seem to have fallen short in tackling the scale and complexity of the phenomena of misinformation.
- Sustainability policies and practices in public sector organisations: the case of the portuguese central public administrationPublication . Figueira, Inês; Domingues, Ana Rita; Caeiro, Sandra; Painho, Marco; Antunes, Paula; Santos, Rui; Videira, Nuno; Walker, Richard M.; Huisingh, Donald; Ramos, Tomás B.The adoption of sustainability policies and practices in organisations is a rising trend, in particular in companies. Public sector organisations are also following this occurrence but with slower signs. Despite a relevant amount of research work on sustainability practices implemented by private organisations and by some public agencies, central public sectors have been left out of the scope of these studies. The main goal of this research is to identify the sustainability profile (including adopted policies and practices) of the public organisations, using the Portuguese Central Public Administration as a case study. A questionnaire survey was developed and submitted to Portuguese public sector organisations that fulfilled the following criteria: (i) to belong to the Portuguese Central Public Administration and (ii) to have the major area of activity at the national level. The statistical population was also defined on the basis of these criteria. Descriptive statistics and frequency analysis were used to explore the results in the organisations surveyed. The overall results demonstrate a low adoption level of integrated sustainability policies and practices, despite the expected positive trends related with the mandatory social and economic practices. This research contributes to new knowledge by characterising the sustainability profile of the Portuguese central public sector and where actions are needed, leading to a better transition to sustainable societies. The developed questionnaire can be used in other geographical, institutional and cultural contexts to define sustainability profile of worldwide public organisations, working also as a benchmarking tool.
