In this study, we extended a model of the relations among ADHD symptoms, anxiety, and academic performance. Undergraduates (N = 515) completed self-report measures of anxiety (i.e. trait, test, math, and literacy) and ADHD symptoms. During the study, they completed math and literacy measures and reported their current (i.e. state) anxiety three times. There were significant correlations among ADHD symptoms and all measures of anxiety. However, neither ADHD symptoms nor trait anxiety were correlated with math or literacy performance. Test-anxious students (...) reported increasing state anxiety as the study progressed. In contrast, math-anxious students reported increased state anxiety following the math tasks but not the literacy tasks and literacy-anxious students reported increased state anxiety following the literacy tasks but not the math tasks. With respect to performance, math-anxious students had worse math performance and literacy-anxious students had worse literacy performance whereas test anxiety was not directly related to performance on either math or literacy tasks. Patterns of relations did not differ for men and women, but, except for literacy anxiety, women reported higher levels of all types of anxiety. These results could help educators understand how affective responses are related to university students’ academic performance. (shrink)

We present an experimental test of the validity of the Pauli Exclusion Principle for electrons based on the concept put forward a few years ago by Ramberg and Snow. In this experiment we perform a very accurate search of X-rays from the Pauli-forbidden atomic transitions of electrons in the already filled 1S shells of copper atoms. Although the experiment has a simple structure, it poses deep conceptual and interpretational problems. Here we describe the experimental method and recent experimental results, which (...) we interpret as an upper limit for the probability to violate the Pauli Exclusion Principle. We present also future plans to upgrade the experimental apparatus using Silicon Drift Detectors. (shrink)

Background Metaphors are central to the human understanding of complex issues; through the immediate associations they evoke and frame problems and suggest solutions. Our suggestion of Music in the Park as a metaphor for health systems reform brings to the forefront the environmentally diverse but bounded spaces of health services that offer a variety of attractors within their confines, while pushing into the background organizational and economic concerns.Reflections Parks, like health services, are embedded in their local landscape, serving their communities, (...) but most importantly parks are public spaces, publically funded, ideally offering universal access and equity and to be shared by all who want to go there.Music, like health, is tangible, technical and scientific, yet ultimately experiential and based on meaning. While it encompasses a wide range of styles and approaches, music making requires as its most important skill active listening which brings with it to be ‘in the moment’, to take personal risks and to draw energy and inspiration from the participants. Hence ‘audiences’ are equally active participants because music only has meaning if it internally resonates with the listener and only can exist in what is a co-constructed experience.Conclusions Music in the Park is a metaphor for primary health care systems based on shared values of experts and unique local communities. Health professionals are players in this arena, who develop and practise the full range of their skills in response to individual and community needs and preferences. Their leadership works through inspiration and empowerment, making patients ‘co-producers’ of their own health and ‘co-shapers’ of their health services. (shrink)

Mirror neurons may play a role in representing not only signs but also their meaning. Because actions are the only aspect of behavior that are inter-individually accessible, interpreting meanings in terms of actions might explain how meanings can be shared. Behavioral evidence and artificial life simulations suggest that seeing objects or processing words referring to objects automatically activates motor actions.

We begin by taking “naturalism” in the sense in which P. F. Strawson (“Scepticism, Naturalism and Transcendental Arguments”, 1985) presented Wittgenstein’s anti-sceptical arguments as “naturalistic”. According to Strawson, this naturalism connects the philosophy of Wittgenstein with that of Hume. Then, we proceed to compare Hume’s and Wittgenstein’s positions and establish a tenet common to them, which we qualify as “meta‐philosophical”: philosophy rests on a bedrock that resists our demands of justification, a contingent “so we are, so we act” that is (...) beyond philosophical analysis. But this negative thesis leads to differentcommitments in each philosopher: a commitment with the autonomy of nature in the case of Hume, and a commitment with the autonomy of grammar in the case of Wittgenstein. Next, we analyze the epistemological implications of each commitment, particularly with reference to the status of natural science. We find a deep divergence between Hume and Wittgenstein on this point, so that the former, but not the latter, could still be labelled as “naturalist” in a positive, more substantial sense. Our central point here is the difficulty to give a naturalistic interpretation of such Wittgensteinian notions as “language game” or “form of life”. Finally, we stress that the distance between Hume and Wittgenstein is most clearly evidenced when we consider the normative (moral) implications of Hume’s concept of nature, which are completely absent from Wittgenstein’s approach, this being a feature of Wittgenstein’s philosophy that remained unchanged all along his work.

In 2017, Italy passed a law that provides for a systematic discipline on informed consent, advance directives, and advance care planning. It ranges from decisions contextual to clinical necessity through the tool of consent/refusal to decisions anticipating future events through the tools of shared care planning and advance directives. Nothing is said in the law regarding the issue of physician assisted suicide. Following the DJ Fabo case, the Italian Constitutional Court declared the constitutional illegitimacy of article 580 of the criminal (...) code in the part in which it does not exclude the punishment of those who facilitate the suicide when the decision has been freely and autonomously made by a person kept alive by life-support treatments and suffering from an irreversible pathology, the source of physical or psychological suffering that he/she considers intolerable, but fully capable of making free and conscious decisions. Such conditions and methods of execution must be verified by a public structure of the national health service, after consulting the territorially competent ethics committee. This statement admits, within strict and regulated bounds, physician assisted suicide, so widening the range of end-of-life decisions for Italian patients. Future application and critical topics will be called into question by the Italian legislator. (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)

The concept of agency is of crucial importance in cognitive science and artificial intelligence, and it is often used as an intuitive and rather uncontroversial term, in contrast to more abstract and theoretically heavy-weighted terms like “intentionality”, “rationality” or “mind”. However, most of the available definitions of agency are either too loose or unspecific to allow for a progressive scientific program. They implicitly and unproblematically assume the features that characterize agents, thus obscuring the full potential and challenge of modeling agency. (...) We identify three conditions that a system must meet in order to be considered as a genuine agent: a) a system must define its own individuality, b) it must be the active source of activity in its environment (interactionalasymmetry) and c) it must regulate this activity in relation to certain norms (normativity). We find that even minimal forms of proto-celular systems can already provide a paradigmatic example of genuine agency. By abstracting away some specific details of minimal models of living agency we define the kind of organization that is capable to meet the required conditions for agency (which is not restricted to living organisms). On this basis, we define agency as an autonomous organization that adaptively regulates its coupling with its environment and contributes to sustaining itself as a consequence. We find that spatiality and temporality are the two fundamental domains in which agency spans at different scales. We conclude by giving an outlook to the road that lies ahead in the pursuit to understand, model and synthesis agents. (shrink)
