Bohmian mechanics is a realistic interpretation of quantum theory. It shares the same ontology of classical mechanics: particles following continuous trajectories in space through time. For this ontological continuity, it seems to be a good candidate for recovering the classical limit of quantum theory. Indeed, in a Bohmian framework, the issue of the classical limit reduces to showing how classical trajectories can emerge from Bohmian ones, under specific classicality assumptions. In this paper, we shall focus on a technical problem that (...) arises from the dynamics of a Bohmian system in bounded regions; and we suggest that a possible solution is supplied by the action of environmental decoherence. However, we shall show that, in order to implement decoherence in a Bohmian framework, a stronger condition is required rather than the usual one. (shrink)

Whitehead, in his famous book "Process and Reality", proposed a definition of point assuming the concepts of “region” and “connection relation” as primitive. Several years after and independently Grzegorczyk, in a brief but very interesting paper proposed another definition of point in a system in which the inclusion relation and the relation of being separated were assumed as primitive. In this paper we compare their definitions and we show that, under rather natural assumptions, they coincide.

This paper aims to clarify some conceptual aspects of decoherence that seem largely overlooked in the recent literature. In particular, I want to stress that decoherence theory, in the standard framework, is rather silent with respect to the description of (sub)systems and associated dynamics. Also, the selection of position basis for classical objects is more problematic than usually thought: while, on the one hand, decoherence offers a pragmatic-oriented solution to this problem, on the other hand, this can hardly be seen (...) as a genuine ontological explanation of why the classical world is position-based. This is not to say that decoherence is not useful to the foundations of quantum mechanics; on the contrary, it is a formidable weapon, as it accounts for a realistic description of quantum systems. That powerful description, however, becomes manifest when decoherence theory itself is interpreted in a realist framework of quantum mechanics. (shrink)

It is shown the complete equivalence between the theory of continuous (enumeration) fuzzy closure operators and the theory of (effective) fuzzy deduction systems in Hilbert style. Moreover, it is proven that any truth-functional semantics whose connectives are interpreted in [0,1] by continuous functions is axiomatizable by a fuzzy deduction system (but not by an effective fuzzy deduction system, in general).

This study investigated how gender shapes the relationships between classroom environment, achievement goals and maths performance. Seventh-grade students (N?=?498) from five urban secondary schools filled in achievement goal orientations and classroom environment scales at the beginning of the second semester. Maths performance was assessed as an average grade four months later. The results indicated gender differences in the perception of teacher and peers support, achievement goals and maths performance. The effects of goal orientations, teacher and peers support on achievement were (...) moderated by gender. Furthermore, the interaction between classroom environment and performance goals on maths grades varied with gender. In the boys? sample, performance-avoidance goals interacted with teacher support, while in the girls? sample, performance-approach goals interacted with peers support in predicting maths grades. The educational implications of these gender differences are discussed. (shrink)

In the last decade, the financial underground markets evolved in a surprisingly way, around the world. Eastern Europe is a significant region, where illegal activities associated with the shadow economy became a real problem that affects the governments stability, the economical, political and social status. Due to the influence of old regimes and the current tolerance of the Eastern European nations, this underground corridors emphasize the risk of interfering with the financing platforms of international terrorism or organized crime.

This paper is about a special version of PDL, proposed by Marcus Kracht, for reasoning about sibling ordered trees. It has four basic programs corresponding to the child, parent, left- and right-sibling relations in such trees. The original motivation for this language is rooted in the field of model-theoretic syntax. Motivated by recent developments in the area of semi-structured data, and, especially, in the field of query languages for XML (eXtensible Markup Language) documents, we revisit the language. This renewed interest (...) comes with a special focus on complexity and expressivity aspects of the language, aspects that have so far largely been ignored. We survey and derive complexity results, and spend most of the paper on the most important open question concerning the language: what is its expressive power? We approach this question from two angles: Which first-order properties can be expressed? And which second-order properties? While we are still some way from definitive answers to these questions, we discuss two first-order fragments of the PDL language for ordered trees, and show how the language can be used to express some typical (second-order) problems, like the boolean circuit and the frontier problem.

Background:Nurses and nursing students appear vulnerable to moral distress when faced with ethical dilemmas or decision-making in clinical practice. As a result, they may experience professional dissatisfaction and their relationships with patients, families, and colleagues may be compromised. The impact of moral distress may manifest as anger, feelings of guilt and frustration, a desire to give up the profession, loss of self-esteem, depression, and anxiety.Objectives:The purpose of this review was to describe how dilemmas and environmental, relational, and organizational factors contribute (...) to moral distress in undergraduate student nurses during their clinical experience and professional education.Research design:The research design was a systematic literature review.Method:The search produced a total of 157 articles published between 2004 and 2014. These were screened with the assessment sheet designed by Hawker and colleagues. Four articles matched the search criteria (one quantitative study and three qualitative), and these were separately read and analyzed by the researchers. The process of review and analysis of the data was supervised by a colleague experienced in moral distress who provided an independent quality check.Ethical consideration:Since this was a systematic review, no ethical approval was required.Findings:From the analysis, it emerged that inequalities and healthcare disparities, the relationship with the mentor, and students’ individual characteristics can all impact negatively on the decisions taken and the nursing care provided, generating moral distress. All these factors condition both the clinical experience and learning process, in addition to the professional development and the possible care choices of future nurses.Conclusion:Few studies dealt with moral distress in the setting of nurse education, and there is a knowledge gap related to this phenomenon. The results of this review underline the need for further research regarding interventions that can minimize moral distress in undergraduate nursing students. (shrink)

IntroductionPalliative care is an emotionally and spiritually high-demanding setting of care. The literature reports on the main issues in order to implement self-care, but there are no models for the organization of the training course. We described the structure of training on self-care and its effects for a Hospital Palliative Care Unit.MethodWe used action-research training experience based mostly on qualitative data. Thematic analysis of data on open-ended questions, researcher’s field notes, oral and written feedback from the trainer and the participants (...) on training outcomes and satisfaction questionnaires were used.ResultsFour major themes emerged: “Professional role and personal feelings”; “Inside and outside the team”; “Do I listen to my emotions in the care relationship?”; “Death: theirs vs. mine.” According to participants’ point of view and researchers’ observations, the training course resulted in ameliorative adjustments of the program; improved skills in self-awareness of own’s emotions and sharing of perceived emotional burden; practicing “compassionate presence” with patients; shared language to address previously uncharted aspects of coping; allowing for continuity of the skills learned; translation of the language learned into daily clinical practices through specific facilitation; a structured staff’s support system for emotional experiences.DiscussionSelf-care is an important enabler for the care of others. The core of our intervention was to encourage a meta-perspective in which the trainees developed greater perspicacity pertaining to their professional role in the working alliance and also recognizing the contribution of their personal emotions to impasse experienced with patients.

The ongoing Coronavirus disease 2019 (COVID-19) pandemic is disrupting most specialized healthcare services worldwide, including those for high-risk newborns and their families. Due to the risk of contagion, critically ill infants, relatives and professionals attending neonatal intensive care units (NICUs) are undergoing a profound remodeling of the organization and quality of care. In particular, mitigation strategies adopted to combat the COVID-19 pandemic may hinder the implementation of family-centered care within the NICU. This may put newborns at risk for several adverse (...) effects, e.g., less weight gain, more nosocomial infections, increased length of NICU stay as well as long-term worse cognitive, emotional, and social development. This article aims to contribute to deepening the knowledge on the psychological impact of COVID-19 on parents and NICU staff members based on empirical data from the literature. We also provided evidence-based indications on how to safely empower families and support NICU staff facing such a threatening emergency, while preserving the crucial role of family-centered developmental care practices.

Faut-il définir la phénoménologie comme une discipline transcendantale? Si toute phénoménologie consiste en un " dire les phénomènes " (legein ta phainomena) qui les approche et les décrit tels qu'en eux-mêmes, le logos phénoménologique doit-il être compris exclusivement - ou même principalement - en référence à la logique mathématique issue de Frege? Enfin, qu'en est-il de la phénoménologie dans son rapport à la métaphysique, non pas au sens " scolaire " du terme, mais dans celui - que lui ont conféré (...) Nietzsche, Bergson et Heidegger - d'une configuration historique unitaire de la pensée occidentale dans son ensemble? Ces trois questions parcourent ce recueil d'études et lui confèrent sa cohésion interne. À travers elles, il s'agit de se frayer un chemin vers la question de l'apparaître en tant que tel, qu'Héraclite a placée au ceux du questionnement de la " philosophie " naissante, et que l'entreprise phénoménologique ne peut manquer de soulever et, à son tour, de perpétuer.

The paper explains why the de Broglie–Bohm theory reduces to Newtonian mechanics in the macroscopic classical limit. The quantum-to-classical transition is based on three steps: (i) interaction with the environment produces effectively factorized states, leading to the formation of _effective wave functions_ and hence _decoherence_; (ii) the effective wave functions selected by the environment—the pointer states of decoherence theory—will be well-localized wave packets, typically Gaussian states; (iii) the quantum potential of a Gaussian state becomes negligible under standard classicality conditions; therefore, (...) the effective wave function will move according to Newtonian mechanics in the correct classical limit. As a result, a Bohmian system in interaction with the environment will be described by an effective Gaussian state and—when the system is macroscopic—it will move according to Newtonian mechanics.

A main identifying factor of professions is professionals' willingness to comply with ethical and professional standards, often defined in a code of ethics and conduct. In a period of intense nursing mobility, if the public are aware that health professionals have committed themselves to the drawing up of a code of ethics and conduct, they will have more trust in the health professional they choose, especially if this person comes from another European Member State. The Code of Ethics and Conduct (...) for European Nursing is a programmatic document for the nursing profession constructed by the FEPI (European Federation of Nursing Regulators) according to Directive 2005/36/EC On recognition of professional qualifications , and Directive 2006/123/EC On services in the internal market, set out by the European Commission. This article describes the construction of the Code and gives an overview of some specific areas of importance. The main text of the Code is reproduced in Appendix 1. (shrink)

IntroductionDignity therapy is brief psychotherapy targeting psychological and existential suffering among patients with a life-limiting illness. Studies have been conducted on the use of DT by healthcare professionals. In Italy, the current legislation defines that any form of psychotherapy may be performed exclusively by psychotherapists. Consequently, this intervention is unlikely to be used by other healthcare professionals. Herein, we will describe a training on DT not as a psychotherapy intervention but as a narrative intervention for non-psychotherapists health care professionals. Finally, (...) we will explore the potential enablers/barriers as experienced by palliative care physicians and nurses.MethodsThe study was conducted in the Psycho-Oncology Unit within the Cancer Research Hospital of Reggio Emilia. It consisted of an exploratory qualitative case study. Data were collected employing observations and interview data and thematically analyzed.ResultsThe training was attended by six physicians and ten nurses and took place during two-afternoon sessions for 10 h. Two participants put their training into practice and administered DT under the supervision of a psychotherapist. Data analysis highlighted five overarching themes relating to the training experience and direct use of DT, namely, time required, psychological skills, patient’s disease awareness, patient’s life history, and distinguishing DT from Advance Care Planning.ConclusionPalliative care professionals found DT to be a valuable non-pharmacological hospital-based intervention to address the person beyond the patient and his clinical conditions. In our experience, considering that in Italy, psychotherapy is an intervention that psychotherapists can only perform, it can help organize different training on DT for psychotherapists and other healthcare professionals.

Le temps est-il fondamentalement une détermination du sujet? A la suite d'Augustin, des philosophies aussi différentes que celles de Bergson, Husserl ou Heidegger n'hésitent pas à le soutenir : le temps n'est pas d'abord dans les choses, mais il provient, plus originairement, des actes, des attitudes ou des comportements par lesquels un sujet (ou, éventuellement, un Dasein) s'attend ou se souvient, anticipe des possibles ou décide de lui-même, c'est-à-dire temporalise dans leur unité indissoluble l'avenir, le passé et le présent. C'est (...) cette thèse que le présent ouvrage s'efforce de discuter et de soumettre à un examen critique. Quelle compréhension du temps au cours de la métaphysique a rendu possible sa " subjectivation "? N'est-ce pas d'abord une certaine saisie du phénomène temporel comme phénomène intratemporel? Et cette interprétation, dont il devient possible d'entreprendre une généalogie à la lumière des analyses de Platon, Aristote et Augustin, ne prescrit-elle pas son cadre conceptuel à la métaphysique elle-même? Mais, si la temporalité n'est pas pensable à l'aune de la subjectivité métaphysique (dont le Dasein, à certains égards du moins, constitue l'ultime figure), n'est-il pas requis, pour tenter d'en produire une phénoménologie, de changer de fil conducteur? C'est en ce point que le présent ouvrage rejoint le projet de L'événement et le monde, celui d'une herméneutique événementiale de l'humain, dont il constitue à la fois l'approfondissement et l'achèvement.

Background:Prisons are contexts where nurses are required to have specific skills to ensure that, in a setting designed for the expiation of crime, prisoners receive the same type of care as anyone else. But this is not always the case, giving rise to ethical issues.Research questions:‘How do correctional nurses describe their working experience in prisons? What issues emerged?’Methodology:This is a qualitative descriptive study. Following purposive sampling, we conducted five focus groups. Thematic analysis was used to analyse the data.Participants and research (...) context:Our sample included 31 correctional nurses in seven prisons in Northern Italy.Ethical considerations:The scientific merit of this study was recognized by the Academic Board of the University of Genoa. Approval to conduct the study was obtained from the Liguria Regional Government that funded this study and from the Local Health Authority that was the prison nurses’ employer. Formal consent was obtained from all the nurses who volunteered to participate in this study.Findings:Five themes emerged from the focus groups: prisoners’ healthcare needs, negotiation between custody and care, satisfaction of working in prisons, obstacles to quality care and safety. ‘Manipulation’ was a transversal theme that emerged from all the focus groups.Discussion:The problems generated by the clash between prison security and nursing care priorities did not enable nurses to practice autonomously and provide the best possible to care prisoners, giving rise to ethical issues and moral distress. This in turn causes high nursing turnover rates that negatively impact continuum of care.Conclusion:In Italy, correctional nurses urgently require specific education interventions with the participation of all those who work in prisons. Interventions based on the post-modern concept of restorative nursing could offer prison nurses the opportunity to both resolve ethical issues and reduce moral distress. (shrink)
