Background: Causal reasoning as a way to make a diagnosis seems convincing. Modern medicine depends on the search for causes of disease and it seems fair to assert that such knowledge is employed in diagnosis. Causal reasoning as it has been presented neglects to some extent the conception of multifactorial disease causes. Goal: The purpose of this paper is to analyze aspects of causation relevant for discussing causal reasoning in a diagnostic context.

Food allergy represents an increasing public health issue, and a large number of food control authorities have provided regulations aimed to minimize the risk of allergic reaction for sensitized consumers. The Food and Agriculture Organization of the United Nations together with the World Health Organization established the Codex Alimentarius Commission whose main goal is to protect the consumers’ health. To purse this task the Commission listed the foods and ingredients causing the most severe allergic reactions that should be labelled. It (...) has been reported that some cases of specific foods hypersensitivity display a different prevalence among different Countries. Thus, the European Union drew up a list of mandatory allergens longer than that provided by Codex Alimentarius. As a consequence of the complexity of the legal phraseology of the European Union and/or European Community the Regulations and/or Directives were differently translated in all EC/EU official languages determining possible misinterpretations of the legislation. Moreover, food labelling regulations were also established with the goal to promote the consumers’ conscious choice about what they eat. Starting from the case of the fermented beverages, we analysed the European legislative scenario concerning the allergen labelling of the last fifteen years, highlighting that mistranslations, misinterpretations and lack of information in the EU Regulations might lead to health and ethical issues.

In one part of his The Dusk of Civilization, Arturo Labriola doubts the fact that races are historical “creations.” We believe this is precisely what is in question and take the opportunity to pay tribute to the multifaceted, disorderly, yet genial notions of this thinker. All the racist theories of Rosenberg, Hitler, Italian racists, etc. can not withstand the weakest blows of science. Questions of blood, origin, etc., are nothing but empty words in our modest opinion. Nevertheless, it is a (...) fact that the inhabitants of the world differentiate themselves through particular characteristics — physical type, appearance, religion, morality, ethics, economics — in different categories.

Resumen: El artículo busca observar el hecho religioso mapuche, a partir de la reflexión de Rudolf Otto respecto de lo numinoso y lo santo. Para ello se utiliza su metodología de análisis fenomenológico aplicada a los conceptos de mysterium, tremendum y fascinans o las dimensiones del temor, incorporadas en la cultura mapuche. Se concluye que el análisis de estos diversos momentos de la experiencia santo-numinoso en la vida religiosa del mapuche, permite constatar el dinamismo existente en la idea religiosa del (...) mapuche, lo que a su vez representa adecuadamente la relación entre el hombre religioso y lo santo.: This article seeks to observe the Mapuche religious fact, starting from Rudolf Otto’s reflection on the numinous and the holy. For this, it uses its methodology of phenomenological analysis applied to the concepts of mysterium, tremendum and fascinans or the dimensions of fear, incorporated in the Mapuche culture. It is concluded that the analysis of these different moments of the saint-numinous experience in the religious life of the mapuche, allows to verify the dynamism existing in the religious idea of ​​the mapuche, which in turn represents adequately the relationship between religious man and the Holy.

Even today, film restoration is a challenge, because it involves multidisciplinary competences: from analogue film inspection and conservation to digitisation and image enhancement. In this context, thanks to the high manageability of digital files, the film restoration workflow often follows a digitisation step, which presents many approximations and issues that are often ignored. In this work, we propose an alternative approach to the issues commonly encountered in film restoration aiming at restoring the original colour appearance, through models of human colour (...) perception.

Burnout is a well-documented entity in Care Workers population, affecting up to 50% of physicians, just as it is equally well established that managing an infectious disease outbreaks, such as confirmed in the COVID-19 pandemic, increases Post-Traumatic Stress Disorder and the psychological burden. Mental health support, in the form of formal or remote sessions, has been shown to be helpful to health care staff, despite the organizational difficulties in an emergency. During the first emergence of COVID-19 in Italy, the Scientific (...) Institute for Research, Hospitalization and Health Care Istituto di Ricovero e Cura a Carattere Scientifico Policlinico San Matteo Foundation, the Italian hospital that treated “patient 1,” has activated an agreement with the Soleterre Foundation, an international Non-Governmental Organization that manages health emergency projects, to provide psychological support. A task force of psychologists was created with the aim of designing and administering a Therapeutic Mental Health Assessment for COVID-19 Care Workers to evaluate and support health care workers’ mental health. The assessment battery was developed to evaluate symptoms and behaviors associated with trauma and the corresponding maladaptive behaviors. Once the TMHA COVID-19 CWs had been developed, the team of psychologists regularly visited healthcare staff in the ward to administer it. One hundred seven care workers across Intensive Care Units, the emergency room and medical ward were administered the TMHA COVID-19 CWs. PTSD symptoms were reported as severe by 13% of the population. Depressive symptoms as severe for 7% and Anxiety symptoms as severe for 14%. Severe psychotic symptoms were experienced by 2% and severe suicidal thoughts by 1% of the population. The possibility of acting upon the results of the TMHA COVID-19 CWs allowed an early intervention through individual session beyond the cut-off level for PTSD in NSESSS. In fact, 280 individual support sessions were offered. Therefore, we considered our project a protective and support factor for healthcare workers’ mental well-being and we recommend implementing a mental health screening program in ward involved in COVID-19 patients’ care.

Theater internationalization is a phenomenon of recent concern in Latin-American regions. This internationalization favors countries’ cultural visibility and artistic and critic exchange as well as new economic benefits, among others. International circulation of theatrical plays leads to the creation of a repertoire –which I call an “exportation repertoire”–, that projects a cultural image of the country of origin. This image emerges as a result of a construction mediated by selection. The study of chilean plays presented abroad allows to observe the (...) coincidences or divergences of the repertoire, identify different aspects involved in international circulation and meditate about the cultural image projected by theater.

In On Nature and Language Noam Chomsky develops his thinking on the relation between language, mind and brain, integrating current research in linguistics into the burgeoning field of neuroscience. This 2002 volume begins with a lucid introduction by the editors Adriana Belletti and Luigi Rizzi. This is followed by some of Chomsky's writings on these themes, together with a penetrating interview in which Chomsky provides the clearest and most elegant introduction to current theory available. It should make his Minimalist (...) Program accessible to all. The volume concludes with an essay on the role of intellectuals in society and government. Nature and Language is a significant landmark in the development of linguistic theory. It will be welcomed by students and researchers in theoretical linguistics, neurolinguistics, cognitive science and politics, as well as anyone interested in the development of Chomsky's thought.

The PBR theorem gives insight into how quantum mechanics describes a physical system. This paper explores PBRs’ general result and shows that it does not disallow the ensemble interpretation of quantum mechanics and maintains, as it must, the fundamentally statistical character of quantum mechanics. This is illustrated by drawing an analogy with an ideal gas. An ensemble interpretation of the Schrödinger cat experiment that does not violate the PBR conclusion is also given. The ramifications, limits, and weaknesses of the PBR (...) assumptions, especially in light of lessons learned from Bell’s theorem, are elucidated. It is shown that, if valid, PBRs’ conclusion specifies what type of ensemble interpretations are possible. The PBR conclusion would require a more direct correspondence between the quantum state ) and the reality it describes than might otherwise be expected. A simple terminology is introduced to clarify this greater correspondence. (shrink)

One of the cornerstones of modern medicine is the search for what causes diseases to develop. A conception of multifactorial disease causes has emerged over the years. Theories of disease causation, however, have not quite been developed in accordance with this view. It is the purpose of this paper to provide a fundamental explication of aspects of causation relevant for discussing causes of disease.The first part of the analysis will discuss discrimination between singular and general causality. Singular causality, as in (...) the specific patient, is a relation between a concrete sequence of causally linked events. General causation, e.g. as in disease etiology, means various categories of causal relations between event types. The paper introduces the concept of a reference case serving as a source for causal inference, reaching beyond the concept of general causality. (shrink)

A recent no-go theorem gives an extension of the Wigner’s Friend argument that purports to prove the “Quantum theory cannot consistently describe the use of itself.” The argument is complex and thought provoking, but fails in a straightforward way if one treats QM as a statistical theory in the most fundamental sense, i.e. if one applies the so-called ensemble interpretation. This explanation is given here at an undergraduate level, which can be edifying for experts and students alike. A recent paper (...) has already shown that the no-go theorem is incorrect with regard to the de Broglie Bohm theory and misguided in some of its general claims. This paper’s contribution is three fold. It shows how the extended Wigner’s Friend argument fails in the ensemble interpretation. It also makes more evident how natural a consistent statistical treatment of the wave function is. In this way, the refutation of the argument is useful for bringing out the core statistical nature of QM. It, in addition, manifests the unnecessary complications and problems introduced by the collapse mechanism that is part of the Copenhagen interpretation. The paper uses the straightforwardness of the ensemble interpretation to make the no-go argument and its refutation more accessible. (shrink)

La construcción de Héctor como una figura atractiva para la audiencia del poema iliádico es un tema bien estudiado en la crítica. Se han dado diferen­tes hipótesis y elementos que contribuyen a este efecto, pero hay un claro acuerdo en que el héroe, en particular entre los troyanos, es uno de los que más simpatía despierta en el público a lo largo del poema. Este trabajo se propone estudiar los discursos del héroe y su sintonía con los sentimientos y opiniones (...) del público, y en general con el tono emocional de los diferentes momentos de la performance poética. Se parte de la hipótesis de que, conforme la tragedia de Héctor se desarrolla, la relación entre la percepción de los eventos que se manifiesta en las palabras del héroe y la de la audiencia se hace cada vez más conflictiva, un proceso que se revierte en el momento en que la inminencia de su muerte se hace evidente para el personaje. Así, se intentará demostrar que la identificación de la audiencia con Héctor no es un fenómeno simple y lineal, sino que es manipulado por el poeta para generar expectativas y ansiedad en el público a fin de retener su atención al espectáculo épico.

In this article I will try to show that economic inequality, the militarization of states, hatred and violence are the main causes of most armed conflicts. By supporting my argument upon a line originated in the East, but which is not unknown in Western thought, I propose to go on researching both Gandhian pacifism and some values consciously cultivated by Buddhism, such as the value of universal compassion, which are very important to strengthen a culture of peace.

In this paper we document the developmental trajectory of the complementizer system (CP-system) in Italian by looking at the earliest spontaneous production of eleven young children, whose transcriptions are available on CHILDES. We conducted a novel corpus analysis, tracking down a number of constructions in which the clausal left-periphery is activated. First, we considered the appearance of the different complementizer particles in the CP-system, which overtly realize the three distinct functional projections ForceP, IntP, and FinP. The analysis revealed that children (...) acquiring Italian correctly use these complementizer particles already in the third year of life. Second, we looked for the simultaneous activation of different functional projections within the CP-system. We went through our corpus searching for complex sentences in which more than one constituent was moved to the left periphery. This option is allowed by the adult grammar of Italian and, as our search revealed, it is also attested in the grammar of young children. Soon after their second birthday, sequences in which a left-dislocated Topic and a Wh- element co-occur are attested, directly supporting the existence of a (high) Topic position above FocusP. Moreover, movement in general conforms to the constraints of the adult grammar, with no attested violation of obligatory inversion (a consequence of the Q-Criterion). Importantly, “why-questions” did not require inversion, much as in the adult grammar of Italian. Taken together, children's use of complementizer particles and their activation of multiple landing sites for movement show that 2-year-olds already possess a richly articulated functional structure of the CP-system, aligned to the layered adult structure. In concluding the paper, we also discuss some temporal differences between constructions activating high and low portions of the CP-system. In particular, we detect a temporal precedence for wh-questions over why-questions. Since the former activate a lower projection, this is consistent with the recently proposedGrowing Treeshypothesis, according to which the development of the CP-system proceeds stepwise. (shrink)

Background: The concept of prognosis as a prediction concerning the probable outcome of an attack of disease shows some severe contextual drawbacks in the everyday clinical sense. It is often used to describe possible outcomes of the disease in general, or the progression of a disease course, not the expected course in a particular case. Goal: To render more discriminating uses of the term prognosis, in order to provide the prognosticating physician with a valid tool, comparable to the theoretical basis (...) of diagnostic and therapeutic actions.

The axiomatic bases of Special Relativity Theory (SRT) are thoroughly re-examined from an operational point of view, with particular emphasis on the status of Einstein synchronization in the light of the possibility of arbitrary synchronization procedures in inertial reference frames. Once correctly and explicitly phrased, the principles of SRT allow for a wide range of “theories” that differ from the standard SRT only for the difference in the chosen synchronization procedures, but are wholly equivalent to SRT in predicting empirical facts. (...) This results in the introduction, in the full background of SRT, of a suitable synchronization gauge. A complete hierarchy of synchronization gauges is introduced and elucidated, ranging from the useful Selleri synchronization gauge (which should lead, according to Selleri, to a multiplicity of theories alternative to SRT) to the more general Mansouri–Sexl synchronization gauge and, finally, to the even more general Anderson–Vetharaniam–Stedman’s synchronization gauge. It is showed that all these gauges do not challenge the SRT, as claimed by Selleri, but simply lead to a number of formalisms which leave the geometrical structure of Minkowski spacetime unchanged. Several aspects of fundamental and applied interest related to the conventional aspect of the synchronization choice are discussed, encompassing the issue of the one-way velocity of light in inertial and rotating reference frames, the global positioning system (GPS)’s working, and the recasting of Maxwell equations in generic synchronizations. Finally, it is showed how the gauge freedom introduced in SRT can be exploited in order to give a clear explanation of the Sagnac effect for counter-propagating matter beams. (shrink)

If is often taken for granted that on a rotating disk it is possible to operate a global 3+1 splitting of spacetime such that both lengths and time intervals are uniquely defined in terms of measurements performed by real rods and real clocks at rest on the platform. This paper shows that this assumption, although widespread and apparently trivial, leads to an anisotropy of the velocity of two light beams traveling in opposite directions along the rim of the disk, which (...) in turn implies some recently pointed out paradoxical consequences undermining the self-consistency of the special theory of relativity (SRT). A correct application of the SRT solves the problem and recovers complete internal consistency for the theory. As an immediate consequence, it is shown that the Sagnac effect only depends on the nonhomogeneity of time of the platform and has nothing to do with any anisotropy of the speed of light along the rim of the disk, contrary to an incorrect but widely held idea.

: The open-ended character of natural languages calls for the hypothesis that humans are endowed with a recursive procedure generating sentences which are hierarchically organized. Structural relations such as c-command, expressed on hierarchical sentential representations, determine all sorts of formal and interpretive properties of sentences. The relevant computational principles are well beyond the reach of conscious introspection, so that studying such properties requires the formulation of precise formal hypotheses, and empirically testing them. This article illustrates all these aspects of linguistic (...) research through the discussion of non-coreference effects. The article argues in favor of the formal linguistic approach based on hierarchical structures, and against alternatives based on vague notions of “analogical generalization”, and/or exploiting mere linear order. In the final part, the issue of cross-linguistic invariance and variation of non-coreference effects is addressed. Keywords: Linguistic Knowledge; Morphosyntactic Properties; Unconscious Computations; Coreference; Linguistic Representations Conoscenza linguistica e computazioni inconsce Riassunto: Il carattere aperto del linguaggio naturale avvalora l’ipotesi che gli esseri umani siano dotati di una procedura ricorsiva che genera frasi gerarchicamente organizzate. Relazioni strutturali come il c-comando, espresse su rappresentazioni frasali gerarchiche, determinano tutte le proprietà formali e interpretative delle frasi. I principi computazionali rilevanti sono totalmente al di fuori della portata della coscienza introspettiva e così lo studio di tali proprietà richiede la formulazione di precise ipotesi formali e la loro verifica sperimentale. Questo articolo illustra tutti questi aspetti della ricerca linguistica, esaminando gli effetti di non-coreferenza. Si argomenta in favore dell’approccio linguistico formale basato su strutture gerarchiche e contro alternative basate su vaghe nozioni di “generalizzazione analogica” e/o che impiegano il semplice ordine lineare. Nella parte finale si affronta il tema dell’invarianza e della variazione cross-linguistica degli effetti di non-coreferenza. Parole chiave: Conoscenza linguistica; Proprietà morfosintattiche; Computazioni inconsce; Coreferenzialità; Rappresentazioni linguistiche. (shrink)
