    LD-Algebras beyond i0

    The algebra of embeddings at the I3 level has been deeply analyzed, but nothing is known algebra-wise for embeddings above I3. In this article, we introduce an operation for embeddings at the level of I0 and above, and prove that they generate an LD-algebra that can be quite different from the one implied by I3

    Kunen's proof of the non-existence of Reinhardt cardinals opened up the research on very large cardinals, i.e., hypotheses at the limit of inconsistency. One of these large cardinals, I0, proved to have descriptive-set-theoretical characteristics, similar to those implied by the Axiom of Determinacy: if λ witnesses I0, then there is a topology for Vλ+1 that is completely metrizable and with weight λ (i.e., it is a λ-Polish space), and it turns out that all the subsets of Vλ+1 in L(Vλ+1) have the λ-Perfect Set Property in such topology. In this paper, we find another generalized Polish space of singular weight κ of cofinality ω such that all its subsets have the κ-Perfect Set Property, and in doing this, we are lowering the consistency strength of such property from I0 to κ θ-supercompact, with θ>κ inaccessible

    Ridefinizione dei ruoli professionali: e se provassimo a ri-partire dai pazienti?

    La ri-definizione delle competenze infermieristiche è una necessità determinata dai progressivi cambiamenti del sistema e delle professioni sanitarie. Se da un lato la definizione di quello che gli infermieri possono o non possono fare può rendere più visibile la professione infermieristica, dall’altro anche l’Organizzazione Mondiale della Sanità concorda sul fatto che una definizione rigida non sia realistica. L’evoluzione costante delle tecnologie e dei sistemi ridisegna i confini tra le professioni sanitarie. Il dibattito attuale è fortemente centrato sulle professioni (cosa perde o guadagna ciascuna professione, aumento o perdita di potere e responsabilità) ma raramente sui bisogni dei pazienti

    Molte Regioni hanno affrontato con vari interventi il sostegno della permanenza a domicilio dei pazienti con malattie croniche invalidanti e bisogni assistenziali complessi. Tali interventi vanno dall’accesso facilitato ai servizi di assistenza domiciliare integrata pubblici o convenzionati, o da forme di assistenza indiretta come l’erogazione di un assegno di cura mensile, ad azioni di formazione rivolte ai soggetti con funzioni di caregiver. Alcune Regioni, in risposta alle richieste delle Associazioni di malati e familiari, hanno assunto delle decisioni per preparare e autorizzare i caregiver a svolgere attività sanitarie. In questo editoriale si propongono alcune riflessioni a partire da una iniziativa della Regione Emilia-Romagna, che ha sollevato un vivace dibattito e che vogliamo utilizzare come occasione per riflettere sui rapporti tra infermieri e caregiver: tematica sulla quale la professione ha molta esperienza nella pratica quotidiana, ma ha ancora molte pagine da scrivere per esplicitare come pensa di relazionarsi nella complessità di bisogni e interventi di cui sempre più le famiglie si fanno carico e per cui rivendicano un ruolo più attiv

    DESCRIPTIVE PROPERTIES OF I2-EMBEDDINGS

    We contribute to the study of generalizations of the Perfect Set Property and the Baire Property to subsets of spaces of higher cardinalities, like the power set P(λ) of a singular cardinal λ of countable cofinality or products ∏i<ωλi for a strictly increasing sequence ⟨λi | i<ω⟩ of cardinals. We consider the question under which large cardinal hypotheses classes of definable subsets of these spaces possess such regularity properties, focusing on rank-into-rank axioms and classes of sets definable by Σ1-formulas with parameters from various collections of sets. We prove that ω-many measurable cardinals, while sufficient to prove the Perfect Set Property of all Σ1-definable sets with parameters in Vλ∪{Vλ}, are not enough to prove it if there is a cofinal sequence in λ in the parameters. For this conclusion, the existence of an I2-embedding is enough, but there are parameters in Vλ+1 for which I2 is still not enough. The situation is similar for the Baire Property: under I2 all sets that are Σ1-definable using elements of Vλ and a cofinal sequence as parameters have the Baire property, but I2 is not enough for some parameter in Vλ+1. Finally, the existence of an I0-embedding implies that all sets that are Σ1n-definable with parameters in Vλ+1 have the Baire property

    The role of end-of-life communication in contributing to palliative-oriented care at the end-of-life in nursing home

    Background: Clear communication about a person's poor prognosis and limited treatment choices improves the quality of end-of-life care. Aims: To investigate how end-of-life communication may contribute to palliative-oriented care at the end-of-life in nursing homes according to both families' and nurses' perspective. Secondly, to identify the contextual factors internal to the nursing home that may influence the timing and quality of communication. Thirdly, to confirm the foundations for a first theory of end-of-life communication. Method: This study is a descriptive two-tailed embedded multiple-case study. A secondary analysis of 23 family carer-nurse paired interviews was performed. Findings: Several contextual factors influenced the timing and quality of communication that, in turn, impacted end-of-life care by promoting family understanding, fostering shared decision-making between healthcare professionals and resident/family carers, and improving the knowledge of residents' and family carers' preferences (ie drivers of transition towards palliative-oriented care). Family carers' preferences had the strongest influence in guiding the care approach, while residents' preferences were poorly known and had a limited impact on the end-of-life care goal. Complex and dynamic interactions within and between drivers and contextual factors emerged, providing preliminary evidence for a first end-of-life communication theory. Conclusion: Findings suggest the need to promote a familiar atmosphere and quality relationships, and improve the knowledge of a resident's preferences to ensure that end-of-life care is consistent with their desires
