Minimal Forbidden Factors of Circular Words

Minimal forbidden factors are a useful tool for investigating properties of words and languages. Two factorial languages are distinct if and only if they have different (antifactorial) sets of minimal forbidden factors. There exist algorithms for computing the minimal forbidden factors of a word, as well as of a regular factorial language. Conversely, Crochemore et al. [IPL, 1998] gave an algorithm that, given the trie recognizing a finite antifactorial language $M$, computes a DFA recognizing the language whose set of minimal forbidden factors is $M$. In the same paper, they showed that the obtained DFA is minimal if the input trie recognizes the minimal forbidden factors of a single word. We generalize this result to the case of a circular word. We discuss several combinatorial properties of the minimal forbidden factors of a circular word. As a byproduct, we obtain a formal definition of the factor automaton of a circular word. Finally, we investigate the case of minimal forbidden factors of the circular Fibonacci words.Comment: To appear in Theoretical Computer Scienc

Application of a prioritisation scheme for seismic intervention in schools buildings in Italy

A risk management framework has recently been developed to assign priorities for the rehabilitation of school buildings in Italy, and to give timescales within which retrofit or demolition must take place. Since it is not practical to carry out a detailed assessment of the 60,000 Italian state and public schools, the framework is a multiple-level procedure which aims to identify the highest-risk buildings based on filters of increasing detail, and reduces the size of the building inventory at each step. The first risk ranking is based on a strength deficit, which measures the difference between the current design forces defined for the building site and an estimation of the level of seismic resistance which was required at the time of design. The second ranking is based on lateral strength calculations that are already available for a large portion of the Italian masonry building stock, and that are obtained from a survey form that is familiar to Italian engineers. Finally, a simplified displacement-based methodology is used to give a more accurate assessment of seismic risk based on a limited amount of geometrical and material data. The final assessment leads to a capacity ratio and a risk rating, which are used within a transparent procedure to assign priorities for seismic intervention, and timescales within which detailed assessment leading to retrofit or demolition must take place. The first step of the methodology has been applied herein to the school building stock within two Regions in Italy and preliminary results are presented

Safety and Family-Centered Care during Restriction of Hospital Visits due to COVID-19: The Experience of Family Members

Background: Person and Family Centered Care (PFCC) has demonstrated important contributions to health care outcomes. However, in response to the need for safety due to the pandemic COVID-19, measures were taken to restrict hospital visits. So, the aim of this study was to understand the healthcare experience of family members of patients hospitalized during the pandemic period regarding safety and person- and family-centered care. Methods: Qualitative interpretative study, conducted through semi-structured interviews with six family members of people hospitalized during the pandemic period. Content analysis was performed using Atlas.ti software version 22 (Berlin, Germany) and Bardin’s methodology. Results and Conclusions: Restrictions on hospital visits due to the pandemic of COVID-19 have led to a distancing of families from the hospital setting and influenced healthcare practice, making it difficult to involve families in the care process. In some cases, healthcare professionals made efforts to provide PFCC, attempting to minimize the impact of the visitation restriction. However, there were reported experiences of care delivery that did not consider social and psychological factors and did not place the person and family at the center of the care process, relying instead on the biomedical model. These practices left out important factors for the provision of safe care. It is crucial, even in pandemic settings, that healthcare professionals provide person- and family-centered care to the extent possible, promoting the safety of care. The family should be involved in the care of the person in the inpatient setting.info:eu-repo/semantics/publishedVersio
