- Utility-driven assessment of anonymized data via clusteringPublication . Ferrão, Maria Eugénia; Prata, Paula; Fazendeiro, PauloIn this study, clustering is conceived as an auxiliary tool to identify groups of special interest. This approach was applied to a real dataset concerning an entire Portuguese cohort of higher education Law students. Several anonymized clustering scenarios were compared against the original cluster solution. The clustering techniques were explored as data utility models in the context of data anonymization, using k-anonymity and (ε, δ)-differential as privacy models. The purpose was to assess anonymized data utility by standard metrics, by the characteristics of the groups obtained, and the relative risk (a relevant metric in social sciences research). For a matter of self-containment, we present an overview of anonymization and clustering methods. We used a partitional clustering algorithm and analyzed several clustering validity indices to understand to what extent the data structure is preserved, or not, after data anonymization. The results suggest that for low dimensionality/cardinality datasets the anonymization procedure easily jeopardizes the clustering endeavor. In addition, there is evidence that relevant field-of-study estimates obtained from anonymized data are biased.
- Person-Centered Care for Older Adults at Residential Care Facilities in the Iberian Peninsula: A Systematic ReviewPublication . Barbosa, Maria Miguel; Dias, Inês Ferreira; Nwaru, Bright; Paúl, Constança; Yanguas, Javier; Afonso, Rosa MarinaThe aging of a population leads to a higher need for gerontological care. Person-centered care for older adults (PCCOA) offers a higher standard of quality at residential care facilities (RCFs). This systematic review is aimed at synthesizing Portuguese and Spanish studies on PCCOA, describing the process of implementation of PCCOA; exploring the impact of interventions based on PCCOA and determining the measurement tools used to evaluate PCCOA. This review was conducted in accordance with the PRISMA guidelines. Thirty-one of the included studies were conducted in Spain, and six were conducted in Portugal. Studies involved the development of models/recommendations, the promotion of resident participation in care processes and education/training. Their results indicated that PCCOA has positive outcomes for staff members and residents.
