Background:Personal values influence nursing students’ development of professional values, which affect professional outcomes, and how nursing students react to different situations. Personal values can be shaped by different factors, including culture, gender, and age.Aims:To explore personal values held by nursing students, and to verify if and how gender and year of study affect nursing students’ personal values.Research design:A multicenter, cross-sectional study was used.Participants and research context:The whole population of nursing undergraduate students available at the time was recruited from eight centers (...) of two Universities, composing a sample of 947 students. Demographic data were collected and it was administered the Portrait Values Questionnaire.Ethical considerations:Ethical approval was obtained from the Institutional Review Boards of the University of the participating centers.Findings:The study sample was mainly composed of young (92.6%, n = 877), female (77.3%, n = 732), Italian (95.8%, n = 907), and unmarried (98.6%, n = 934) nursing students. The most important value for nursing students, consistently through the years of nursing school, was Self-transcendence, which has the motivational emphasis on helping others and selflessness. Then, we found that male students had higher levels of Power (p < 0.001) and Achievement (p = 0.031), while female students outscored male students in Benevolence (p = 0.005) and Security (p = 0.006). Year of study showed no statistically significant difference.Discussion:Nursing students express high levels in hetero-directed values. Male nursing students, although they choose a stereotypically feminine profession, outscored females in stereotypical masculine values such as dominance and success. This is the first study that describes the personal value profile of undergraduate nursing students, according to the Theory of Basic Human Values, and it is a starting point for future research.Conclusion:Nursing educators might want to consider the findings from this study while guiding students in developing awareness for their personal values.

The naïve idea of “size” for collections seems to obey both Aristotle’s Principle: “the whole is greater than its parts” and Cantor’s Principle: “1-to-1 correspondences preserve size”. Notoriously, Aristotle’s and Cantor’s principles are incompatible for infinite collections. Cantor’s theory of cardinalities weakens the former principle to “the part is not greater than the whole”, but the outcoming cardinal arithmetic is very unusual. It does not allow for inverse operations, and so there is no direct way of introducing infinitesimal numbers. Here (...) we maintain Aristotle’s principle, instead halving Cantor’s principle to “equinumerous collections are in 1–1 correspondence”. In this way we obtain a very nice arithmetic: in fact, our “numerosities” may be taken to be nonstandard integers. These numerosities appear naturally suited to sets of ordinals, but they depend, for generic sets, on a “labelling” of the universe by ordinals. The problem of finding a canonical way of attaching numerosities to all sets seems to be worth further investigation. (shrink)

One of the difficulties nurses experience in clinical practice in relation to ethical issues in connection with young oncology patients is moral distress. In this descriptive correlational study, the Moral Distress Scale-Paediatric Version (MDS-PV) was translated from the original language and tested on a conventional sample of nurses working in paediatric oncology and haematology wards, in six north paediatric hospitals of Italy. 13.7% of the total respondents claimed that they had changed unit or hospital due to moral distress. The items (...) with the highest mean intensity in the sample were almost all connected with medical and nursing competence and have considerably higher values than frequency. The instrument was found to be reliable. The results confirmed the validity of the MDS-PV (Cronbach’s alpha = 0.959). This study represents the first small-scale attempt to validate MDS-PV for use in paediatric oncology-ematology nurses in Italy. (shrink)

We prove that the opposite of the category of coalgebras for the Vietoris endofunctor on the category of compact Hausdorff spaces is monadic over $\mathsf {Set}$. We deliver an analogous result for the upper, lower, and convex Vietoris endofunctors acting on the category of stably compact spaces. We provide axiomatizations of the associated (infinitary) varieties. This can be seen as a version of Jónsson–Tarski duality for modal algebras beyond the zero-dimensional setting.

This is an interview with Daniel Dennett.

Heath and Tversky (1991, Journal of Risk and Uncertainty 4:5–28) posed that reaction to ambiguity is driven by perceived competence. Competence effects may be inconsistent with ambiguity aversion if betting on own judgement is preferred to betting on a chance event, because judgemental probabilities are more ambiguous than chance events. This laboratory experiment analyses whether ambiguity affects prices and volumes in a double auction market, and contrasts ambiguity aversion to competence effects. In order to test for the presence of competence (...) effects, in the experiment uncertainty is tied to the realisation of events about which the decision maker is more or less knowledgeable. Two experiments are presented: in the first, knowledge is exogenous, whereas in the second the knowledge judgement is endogenous. Market prices provide evidence in favour of the competence hypothesis only when competence is self-assessed. Comparable volumes are observed in both experiments. (shrink)

Histone octamers (hos) and DNA topoisomerase I contribute, along with other proteins, to the higher order structure of chromatin. Here we report on the similar topological requirements of these two protein model systems for their interaction with DNA. Both histone octamers and topoisomerase I positively and consistently respond to DNA supercoiling and curvature, and to the spatial accessibility of the preferential interaction sites. These findings (1) point to the relevance of the topology‐related DNA conformation in protein interactions and define the (...) particular role of the helically phased rotational information; and (2) help to solve the apparent paradoxical behaviour of ubiquitous and abundant proteins that interact with defined DNA sites in spite of the lack of clear sequence consensuses. Considering firstly, that the interactions with DNA of both DNA topoisomerase I and histone octamers are topology‐sensitive and that upon their interaction the DNA conformation is modified; and secondly, that similar behaviours have also been reported for DNA topoisomerase II and histone H1, a topology‐based functional correlation among all these determinants of the higher order structure of chromatin is here suggested.

Il breve saggio si propone di esaminare la centralità della figura materna nell’opera di un ingegnoso costruttore di storie della letteratura italiana del Novecento: Alberto Moravia. La scelta dell’Autore nasce dalla rilevanza della tematica nella sua opera, in cui peraltro è quasi sempre assente il punto di vista femminile delle “voci” delle donne. Ciò sembra paradossale e questa circostanza è di grande interesse critico. In particolare, a dispetto delle interpretazioni più canoniche, secondo cui Moravia – negli scritti realizzati tra il (...) 1929 e il 1964 – ha inteso compiere una “distruzione” dell’immagine materna nel quadro di una visione pessimista della famiglia borghese, dovremo considerare un più complesso e articolato universo materno nello scrittore romano, in cui è possibile ricostruire cinque modelli – la “madre autoritaria”, la “madre-non madre”, la “madre padrona”, la “madre-angelo custode” e la “madre-seduttrice” –, ben esemplificati nei principali romanzi ma che si ritrovano nei racconti che Moravia scrive ininterrottamente dagli anni Trenta agli anni Sessanta, la cui mole ha determinato, ancor oggi, una mancanza di studi sistematici. In secondo luogo, la tematica della madre sarà esaminata nelle trasposizioni cinematografiche italiane delle opere letterarie di Moravia. Va ricordato che il rapporto dello scrittore con il cinema fu particolarmente intenso. Per un verso, la “settima arte” rivestì un ruolo non secondario nella formazione ed esperienza estetica dell’Autore romano, che al cinema si interessò anche professionalmente nelle vesti di critico cinematografico, a partire dal primo dopoguerra, dapprima, per La nuova Europa e Libera stampa, poi, per L’Europeo e L’Espresso, a cui dobbiamo aggiungere l’attività di saggista per numerose riviste specializzate. Per altro verso, il cinema italiano non solo ha attinto a “mani basse” dall’opera di Moravia per sceneggiature di pellicole, che furono pietre miliari della sua storia. L’elenco dei romanzi e racconti adattati al grande schermo rende conto della grande influenza nella cultura italiana degli anni Cinquanta e Sessanta: La provinciale (1953) di Mario Soldati, La romana (1954) di Luigi Zampa, Peccato che sia una canaglia (1954) di Alessandro Blasetti, Racconti romani (1955) di Gianni Franciolini, La ciociara (1960) di Vittorio de Sica, La giornata balorda (1960) di Mauro Bolognini, Risate di gioia (1960) di Mario Monicelli, Agostino (o la perdita dell’innocenza) (1962) di Mauro Bolognini, La noia (1963) di Damiano Damiani, Gli indifferenti (1964) di Francesco Maselli, Le ore nude (1964) di Marco Vicario, La donna invisibile (1969) di Paolo Spinola, Una ragazza piuttosto complicata (1969) di Damiano Damiani, L’amore coniugale (1970) di Dacia Maraini, Il conformista (1970) di Bernardo Bertolucci, e molti altri ancora. Come avremo modo soltanto di accennare, il successo della letteratura moraviana nel mondo del cinema italiano si deve a molteplici fattori, tra cui la raffigurazione dei personaggi e degli ambienti, la focalizzazione su certe tematiche e, non da ultimo, lo stile narrativo, particolarmente adatto alle trasposizioni cinematografiche. Come caso di studio, ci soffermeremo, infine, sulla figura materna della versione filmica de La noia di Damiani, con l’obiettivo di verificare se nel passaggio dal libro alla pellicola, quella particolare connotazione della madre autoritaria abbia subito delle alterazioni. L’ipotesi che muove l’analisi è che la stesura delle sceneggiature, la raffigurazione dei personaggi e la messa in scena delle sequenze filmiche facciano emergere un riadattamento adeguato al largo pubblico, con il sovvertimento dell’andamento cronologico, alcune “lacune” di ordine psicologico nella raffigurazione dei protagonisti e un certo cedimento moralistico alla cultura ancora dominante negli anni ’50 e ’60, in cui la figura materna, sia quando è incattivita dalla povertà che quando è inaridita dalla ricchezza, anela comunque agli affetti familiari, trovando in essi una qualche forma di redenzione.

We offer a novel picture of mathematical language from the perspective of speech act theory. There are distinct speech acts within mathematics, and, as we intend to show, distinct illocutionary force indicators as well. Even mathematics in its most formalized version cannot do without some such indicators. This goes against a certain orthodoxy both in contemporary philosophy of mathematics and in speech act theory. As we will comment, the recognition of distinct illocutionary acts within logic and mathematics and the incorporation (...) of illocutionary force indicators in the formal language for both goes back to Frege’s conception of these topics. We are, therefore, going back to a Fregean perspective. This paper is part of a larger project of applying contemporary speech act theory to the scientific language of mathematics in order to uncover the varieties and regular combinations of illocutionary acts present in it. For reasons of space, we here concentrate only on assertive and declarative acts within mathematics, leaving the investigation of other kinds of acts for a future occasion. (shrink)

This work evaluated the structure of dreams in people affected by schizophrenia. The verbal reports of 123 schizophrenic patients were compared with 123 dream reports from a control group. In accordance with the Jungian conceptualization of, dreams as texts, dream reports were assessed using textual analysis processing techniques.Significant differences were found in textual parameters, showing that the dreams reports of schizophrenic patients differ from those of the control group. It is thus possible that schizophrenia probably underlies changes in the oneiric (...) production and dream reports. This work confirms the value of textual analysis in the study of oneiric material.

In this paper we argue, against a somewhat standard view, that pragmatic phenomena occur in mathematical language. We provide concrete examples supporting this thesis.

A definition of nonstandard universe which gets over the limitation to the finite levels of the cumulative hierarchy is proposed. Though necessarily nonwellfounded, nonstandard universes are arranged in strata in the likeness of superstructures and allow a rank function taking linearly ordered values. Nonstandard universes are also constructed which model the whole ZFC theory without regularity and satisfy the κ-saturation property.

Assuming the existence of an inaccessible cardinal, transitive full models of the whole set theory, equipped with a linearly valued rank function, are constructed. Such models provide a global framework for nonstandard mathematics.

In December 2017, Law 219/2017, ‘Provisions for informed consent and advance directives’, was approved in Italy. The law is the culmination of a year-long process and the subject of heated debate throughout Italian society. Contentious issues are addressed in the law. What emerges clearly are concepts such as quality of life, autonomy, and the right to accept or refuse any medical treatment – concepts that should be part of an optimal relationship between the patient and healthcare professionals. The law maximizes (...) the value of the patient’s time to decide. Every patient is allowed to make choices for the present as well as for the future, conceived as a continuation of the present, and to decide what comes next, based on what he/she already knows. The law identifies three distinct but converging paths towards the affirmation of a care relationship based on reciprocal trust and respect: the possibility to consent to or refuse treatment, the shared care planning, and advance directives. The fundamental point to emerge from the new Italian law is that consensus is an essential connotation of the treatment relationship. Consensus is not limited to the acceptance/rejection of medical treatment but is ongoing. It is projected into the future through shared care planning and advance directives which act as tools for self-determination and the manifestation of the beliefs and preferences of persons unable to express their will. These principles are in line with the idea of appropriate care as evaluated from two different perspectives, one of scientific adequacy and the other commensurate with the individual’s resources, fragility, values, and beliefs. Surely, however, the new law is not the end of the matter on issues such as conscientious objection, which is deeply rooted within the Italian cultural and political debate. In this regard, healthcare institutions and policymakers will be called upon to develop and implement organizational policies aimed at the management of foreseeable conscientious objection in this field.

Workplace Incivility (WI) occurs worldwide and has negative consequences on individuals and organizations. Valid and comprehensive instruments have been used, specifically in English speaking countries, to measure such adverse process at work, but it is not available a validated instrument for research carried out in Spanish speaking countries. In this study we aim to test the psychometric properties of the Matthews and Ritter’s four-item Workplace Incivility Scale (2016) with Spanish workers (N= 407) from different sectors. Participants’ mean age was 38.73 (...) (SD= 10.45) years old and the percentage of female employees was 59.2%. Confirmatory factor analysis using AMOS 19.0 was carried out, presenting a good fit. The internal consistency, convergent and concurrent validity of the scale were examined. Results show good scale reliability and expected high correlations with social undermining. Moreover, the scale related to propensity to leave a job, job satisfaction, and psychological well-being in the expected way. After configural invariance across groups was established, testing for metric invariance and scalar invariance was performed. Considering Δχ² and ΔCFI tests for two nested models, the 4-item scale was invariant when the employment status is considered (permanent vs temporal, full-time vs part-time and supervisor vs non supervisors). Overall, our findings showed good psychometric properties of the shorter version of the Workplace Incivility Scale in Spain. Theoretical and practical implications of this study are discussed.

A nonstandard set theory ∗ZFC is proposed that axiomatizes the nonstandard embedding ∗. Besides the usual principles of nonstandard analysis, all axioms of ZFC except regularity are assumed. A strong form of saturation is also postulated. ∗ZFC is a conservative extension of ZFC.

We study combinatorial principles related to the isomorphism property and the special model axiom in nonstandard analysis.

A definition of nonstandard universe which gets over the limitation to the finite levels of the cumulative hierarchy is proposed. Though necessarily nonwellfounded, nonstandard universes are arranged in strata in the likeness of superstructures and allow a rank function taking linearly ordered values. Nonstandard universes are also constructed which model the whole ZFC theory without regularity and satisfy the $\kappa$-saturation property.
