This study aims to open a critical scenario on the current paradigm of reference for teaching sports techniques by pointing to a methodological perspective that is more in keeping with the theoretical reference framework of the ecological-dynamic approach. Currently, the Constraints-led Approach is considered very useful for teaching sports techniques; however, the transition from pure theory to practice is not so simple and consistent with the heuristic learning paradigm. The purpose is to highlight, starting from the theoretical lines, the methodological (...) applications of the different ways of applying the reference paradigm, analyzing the contrasts of the significant aspects and the uniqueness and unrepeatability of heuristic learning. For this purpose, an in-depth review of the scientific literature was conducted, highlighting the main critical points of the approach, also defined as nonlinear, with the consequent elaboration of operational proposals for the various macro-families of sports.

This article examines humanist works written in the immediate aftermath of Stefano Porcari's failed conspiracy against Pope Nicholas V. While they were designed to flatter the pope and support papal claims to temporal power, these works use images and adopt rhetorical startegies that are republican and not, as one would expect, imperial in origin. The humanists were so devoted not only to classical form, but also to Roman republican ideals that they sometimes present Porcari positively, have heroes of the Roman (...) republic comment on the modern papacy, and construct a strained theory of papal liberty.

The striking color patterns of butterflies and birds have long interested biologists. But how these animals see color is less well understood. Opsins are the protein components of the visual pigments of the eye. Color vision has evolved in butterflies through opsin gene duplications, through positive selection at individual opsin loci, and by the use of filtering pigments. By contrast, birds have retained the same opsin complement present in early-jawed vertebrates, and their visual system has diversified primarily through tuning of (...) the short-wavelength-sensitive photoreceptors, rather than by opsin duplication or the use of filtering elements. Butterflies and birds have evolved photoreceptors that might use some of the same amino acid sites for generating similar spectral phenotypes across 540 million years of evolution, when rhabdomeric and ciliary-type opsins radiated during the early Cambrian period. Considering the similarities between the two taxa, it is surprising that the eyes of birds are not more diverse. Additional taxonomic sampling of birds may help clarify this mystery. (shrink)

The paper presents and discusses the processes and the results of a Systematic Review of the scientific literature conducted with the aim to become aware of how the antisocial behaviour of adolescents are understood and educationally managed. The results show how the phenomenon is understood mainly through an explanatory and experimental epistemological and methodological approach. Such approach aims at identifying several risks and protection factors that determine/influence AB as well as at defining indications on the practices to be implemented for (...) the design of adequate prevention programmes. Based on these results, the paper proposes some critical reflections on a deterministic conception of AB. (shrink)

Affiliation with a scientific area or degree program could affect one´s religious beliefs and acceptance of evolution; however, this issue has been poorly studied. Moreover, little information is available regarding Chilean university scientists’ views on religion and evolution. This study aims to provide the first documentation of the opinion of scientists at a Chilean University with regard to religion and evolution. This was done by conducting a personal survey of first and last year undergraduate students, graduate students, and faculty. We (...) found that nonreligiosity, as well as acceptance of Darwinian evolution, increased with possession of an advanced degree and this correlation was stronger for individuals who study biology and physics in comparison to those who study chemistry. Although less than 30 percent of undergraduate students are atheists/agnostics, more than 70 percent of faculty members are atheist or agnostic. However, most of the surveyed scientists did not see a conflict between science and religion. (shrink)

Context. The identification of the sources that reionized the Universe and their specific contribution to this process are key missing pieces of our knowledge of the early Universe. Faint star-forming galaxies may be the main contributors to the ionizing photon budget during the epoch of reionization, but their escaping photons cannot be detected directly due to inter-galactic medium opacity. Hence, it is essential to characterize the properties of faint galaxies with significant Lyman continuum photon leakage up to z 4 to (...) define indirect indicators allowing analogues to be found at the highest redshift. Aims. Long gamma-ray bursts explode typically in star-forming regions of faint, star-forming galaxies. Through LGRB afterglow spectroscopy it is possible to detect directly LyC photons. Our aim is to use LGRBs as tools to study LyC leakage from faint, star-forming galaxies at high redshift. Methods. Here we present the observations of LyC emission in the afterglow spectra of GRB 191004B at z = 3:5055, together with those of the other two previously known LyC-emitting LGRB, to determine their LyC escape fraction and compare their properties. Results. From the afterglow spectrum of GRB 191004B we determine a neutral hydrogen column density at the LGRB redshift of og =17:2 0:15, and negligible extinction. The only metal absorption lines detected are C iv and Si iv. In contrast to GRB 050908 and GRB 060607A, the host galaxy of GRB 191004B displays significant Ly emission. From its Ly emission and the non-detection of Balmer emission lines we constrain its star-formation rate to 1 SFR 4:7 M yr. 1. We fit the Ly emission with a shell model and find parameters values consistent with the observed ones. The absolute LyC escape fractions we find for GRB 191004B, GRB 050908 and GRB 060607A are of 0:35+0:10.0:11, 0:08+0:05.0:04 and :20+0:05.0:05, respectively. We compare the LyC escape fraction of LGRBs to the values of other LyC emitters found from the literature, showing that LGRB afterglows can be powerful tools to study LyC escape for faint high-redshift star-forming galaxies. Indeed we could push LyC leakage studies to much higher absolute magnitudes. The host galaxies of the three LGRB presented here have all M1600 >.19:5 mag, with the GRB 060607A host at M1600 >.16 mag. LGRB hosts may therefore be particularly suitable for exploring the ionizing escape fraction in galaxies that are too faint or distant for conventional techniques. Furthermore the time investment is very small compared to galaxy studies. (shrink)

Relationships between degree/area of academic formation and religious and Darwinian views are controversial. This study aimed to compare the religious beliefs and acceptance of Darwinian evolution between two contrasting South American scientific communities (Chile and Colombia), accounting for different degrees and areas of academic formation. In 2018, 115 last year bachelor students (surveyed as freshmen in 2014 for a previous study) from Chile, and 283 first/last year bachelor students, graduate students, and professors from Colombia, all belonging to biology, chemistry, or (...) physics, were surveyed. Chilean students/faculty were significantly more agnostic/atheist, more accepting of Darwinian evolution, and less creationist than their Colombian counterparts. Academic degree and area differently affected these views in both countries, as only in Chile there was a clear tendency among biologists and physicists with higher degrees to hold less religious and creationist views. Marked differences between the history, socioeconomic contexts, and especially in high school and university curricula of both countries might explain these results. (shrink)

A conflict of interest is a situation in which a person has competing loyalties or interests that make it difficult to fulfil his or her duties impartially. Conflict of interest is not categorically improper in itself but requires proper management. A SCOPUS literature search was performed for publications on the efficacy/safety of Phospho-Di-Esterase Inhibitors for treating erectile dysfunction. A categorization tool was used to review and classify the publications as supportive/not-supportive for the discussed active ingredient and reporting or not reporting (...) a COI for that specific drug or for the remaining PDEIs. Multivariable binary logistic regression was performed. In the 419 selected records the prevalence of supportive opinions was higher when a COI for the index label was declared. The CoOpCaT showed good internal consistency, discriminative validity and intra/inter-rater agreement. The strongest predictor for a supportive opinion was the total number of financial COIs for the index label. A mild protective effect of the total number of financial COIs for any competitor label was noted. Financial COIs have frequently been associated with bias, and the measures currently adopted to restrain it lack effectiveness. Some evidence for monitoring and/or compensating this bias is reported here, but the ultimate solution remains distant. (shrink)

This article investigates the relationship between political revolutions and the evolution of politics. It discusses the circularity within the concept of revolution through Jacques Derrida’s theory of sovereignty as particularly per Rogues – Two Essays on Reason and The Beast and the Sovereign. Derrida’s notions of wheel and ipseity display ontological prerogatives and evolutionary limits of political revolutions possibly coinciding with reversals hard to turn into linear evolutions, excluding rather than reaffirming circularity. Political revolutions show such incapacity to become evolutionary (...) for politics when lacking ontological substance and resting upon formal contingencies such as new techniques. An ‘alturnative’ notion of sovereignty is proposed as a heuristic criterion to gauge political events’ ‘revolutionary’ quality. This undermines the (r)evolutionary nature of political turns, like those associated with the contemporary digitalisation of politics. The Italian Five Stars Movement’s parable is a case in point of digital political turns whose effect is non-evolutionary for politics. (shrink)

Supervenience is one of the 'hot discoveries' of analytic philosophy, and this collection of essays on the topic represents an examination of it and its application to major areas of philosophy. The interest in supervenience has much to do with the flexibility of the concept. To say that x supervenes on y indicates a degree of dependence without committing one to the view that x can be reduced to y. Thus supervenience is a relationship that has the potential of replacing (...) the traditional notion of dependence, while performing at least part of the function reductive relationships were supposed to fulfil. Moreover, since it is a topic-neutral concept, supervenience has a wide range of applicability. (shrink)

La storia della filosofia come frontiera. L’itinerario di Nicola Abbagnano - ASBTRACT: L’articolo ricostruisce i momenti fondamentali del percorso storiografico di Nicola Abbagnano, a partire dalla sua tesi di laurea del 1923, Le sorgenti irrazionali del pensiero, fino all’articolo Il lavoro storiografico in filosofia : l’intento di questa analisi è mostrare la centralità e la complessità della Storia della filosofia , non riducibile a semplice "appendice" storiografica del periodo esistenzialistico dell’autore. Vengono esaminate in tale prospettiva le premesse teoriche dell’impostazione storiografica (...) di Abbagnano e le difficoltà che sorgono nel concreto lavoro storiografico: la Storia della filosofia si rivela così anche opera teoretica decisiva nel passaggio al neoilluminismo, che risulta caratterizzato da un profondo ripensamento dei rapporti tra storia e filosofia.

Apoptotic pathways have always been regarded as a key‐player in preserving tissue and organ homeostasis. Excessive activation or resistance to activation of cell death signaling may indeed be responsible for several mechanisms of disease, including malignancy and chronic degenerative diseases. Therefore, targeting apoptotic factors gained more and more attention in the scientific community and novel strategies emerged aimed at selectively blocking or stimulating cell death signaling. This is also the case for the TMEM219 death receptor, which is activated by a (...) circulating ligand, the Insulin‐like growth factor binding protein 3 (IGFBP3) and induces a caspase‐8‐dependent apoptosis of the target cells. Interestingly, stimulation of the IGFBP3/TMEM219 axis exerts an anti‐proliferative effect, while blockade of the TMEM219 deleterious signal protects TMEM219‐expressing cells of the endocrine pancreas, lung, and intestine from damage and death. Here, we summarize the most updated reports on the role of the IGFBP3/TMEM219 apoptotic axis in disease conditions, including intestinal disorders and diabetes, and we describe the advancements in designing and testing novel TMEM219‐based targeting approaches in emerging potential clinical applications.

Patterns of memory sharing begin early in one’s life, informing relationships, one’s history, and one’s sense of cultural belonging. Memory sharing among families has been the focus of research investigating the relationship between mental health and intergenerational memory. A burgeoning body of research is showing that intergenerational knowledge of one’s family history is associated with positive mental health and wellbeing. However, research on the specific mechanisms and potential applications of such findings are just beginning to emerge. In particular, studies examining (...) intergenerational storytelling point to the importance of culture and gender as critical factors underlying how stories are told and the extent to which these stories are associated with wellbeing. Such findings hold important promise for the pentation and treatment of mental health issues. As research in this area continues to evolve, the identification and characterization of factors and mechanisms underlying intergenerational family stories and wellbeing may help to guide the integration of family stories into mental health interventions.

In this article, we argue that Paul Ricœur’s hermeneutics of spaces and the aesthetics vision of the landscape as a performance, based on the contemporary theories of Erika Fischer-Lichte, can integrate each other through the mediation of Mikel Dufrenne’s phenomenology of the a priori. In particular, we will show how the representations and the hermeneutics of a landscape as a peculiar “text” are essentially connected with its the pre-reflective experience, which, being made possible by the activation of precise material – (...) and therefore historical and cultural – a priori, can be thus translated into images and words. By intertwining hermeneutics, phenomenology, and performative esthetics we will provide with a non-reductive philosophical description of a landscape, i.e., a definition that does not neglect the aspects of it suggested by its linguistic pre-comprehension and artistic representations.

In Memory, History, Forgetting, Ricœur does not provide us with a clear definition of collective memory. In this article, we will try to show how it could nevertheless be described, based on the same text, as the capacity for recognition, by way of reciprocal attribution, memories that are engraved in temporal spaces and are shared with our neighbors and, through them, with strangers. To verify this hypothesis, we will analyse Ricœur’s reflection on architecture as public memory’s engraving into space, presented (...) for the first time in the text “Architecture et narrativité.” Lastly, we will consider imagination and bodily memory, i.e. habit emanating from the act of inhabiting, as the conditions of possibility for the crystallization of memories in shared places.

BackgroundHeavy media use has been linked to sleep problems in children, which may also extend to the infancy period. While international parent-advisory agencies, such as the American Academy of Pediatrics, advise no screen time before 18 months, parents often do not follow this recommendation. Research on Italian infants’ early access to media is sparse, and only very few studies have investigated links with sleeping habits.MethodTo address this gap, we examined concurrent associations between parent-reported surveys of child technology use and sleeping (...) patterns. The Italian version of the 60 item Comprehensive Assessment of Family Media Exposure Survey, developed as part of a larger international study,, the Brief Screening Questionnaire for Infant Sleep Problems Sadeh, 2004) were completed online by 264 Italian parents of 8- to 36-month-olds and a subset completed the Parenting Stress Index Abidin, 1995) between April 2017 and April 2018.ResultsMore devices located in the child’s room and the more time spent watching TV or using an iPad were associated with less hours of sleep at night. Furthermore, more time spent watching TV or using a smartphone, as well as the number of devices in the room was associated with going to sleep later at night. Instrumental media use was associated with less sleep.ConclusionLike other countries, Italian infants have high levels of exposure to media, and differences in media patterns were associated with sleep patterns. Cultural factors influence both instrumental reasons for media use and sleep practices. Further research should explore how media use may serve to regulate emotion as a function of both contextual factors and individual differences. (shrink)

The political role of architecture in urban space design is still a significant philosophical issue. Starting from the assumption that cities can actually be understood as material texts, Paul Ricoeur’s hermeneutics has described the architecture as a creative mimesis of space. Textual hermeneutics applied to architecture, if crossed with Ricoeur’s reading of ideology and utopia, allows today to qualify the figure of the architect as a critical and transformative narrator of the urban dimension, and, thus, to identify his political task (...) in the imaginative effort of thinking a utopian elsewhere which is, at the same time, rooted in cultural and historical identities of designed places.

Is it possible that children experience something we could judge as the sublime? Some pivotal conjectures have been elicited to positively answer these questions; however, this general topic still stands in need of fuller theoretical and empirical insights. Since taking up this challenge may have important implications in the ever-expanding field of aesthetic education, in this article I will give a philosophical account of the experience of the sublime in 8-10 children, identifying both its plau- sible components and its markers, (...) which opens up future empirical inquiries.

The work examines the influence of the relationship that football players have with significant others on their psychological wellbeing (PWB), adopting a psychosocial perspective. According to this perspective, PWB can be considered a basic condition for an effective talent development and holistic growth of young athletes. Current literature on talent development in sport has been analyzed to support the theoretical hypothesis of psychosocial perspective. Thus, it has been tested empirically through a Structural Equation Model. Analysis reveals a strong and positive (...) influence of some dimensions of the relationships with significant others on the psychological wellbeing, specifically team effort, coach closeness and parental learning climate. Following ANOVA shows that élite players perceive significantly better relationships than sub-élite and amateurs and have significantly higher levels of PWB. Those results provide a first evidence for the importance of relationships within and outside sport for an effective talent development, since they positively influence players’ PWB, that is higher in higher competitive level players. It emerges the necessity to further investigate different aspects of psychological wellbeing and to deepen the knowledge about the meaning of relationship in developmental athletes according to a psychosocial approach.
