Ragione e antiragione nella cultura filosofica europea. Studi per Domenico Conte
No full textPubblicato in onore di Domenico Conte in occasione del festeggiamento dei suoi settant’anni, il volume indaga il tema ragione/antiragione nella cultura filosofica europea, con particolare attenzione allo spazio italo-tedesco. È questa l’ampia regione a partire dalla quale i trentuno contributori del libro, di diversa provenienza (storici della filosofia, ma anche filosofi morali e teoretici, studiosi di estetica, antropologi) ed esperti di diverse fasi del pensiero occidentale (dall’età moderna a quella contemporanea), entrano in dialogo con le Fragen che animano la ricerca di Conte. Una delle cui cifre distintive è rintracciabile nell’attenzione per il complesso e problematico rapporto tra natura e spirito. Quello spirito che – canta Hölderlin in versi cari al festeggiato – proviene dallo spumeggiare dell’onda della vita sulla roccia antica e muta del destino
Compatibilization strategies and analysis of morphological features of poly(butylene adipate-co-terephthalate) (PBAT)/poly(lactic acid) PLA blends: A state-of-art review
No full textPBAT is a compostable biopolyester, potentially obtainable from renewable resources, of great commercial interest. Thanks to its lower price, ease in processability and especially high ductility PBAT will very likely emerge in the next few years as the preeminent flexible bioplastic, ahead of contenders such as polybutylene succinate (PBS) or polycaprolactone (PCL) and it will likely become one of the most important biodegradable plastics, alongside PLA, which stays the major biopolymer for rigid applications. PBAT is often blended with PLA, a rigid bio-based polymer, that lends stiffness. PLA is a very rigid material with low impact resistance, it is, therefore, complementary to PBAT in the design of high performance and multi-functional biodegradable plastics. Despite the great and increasing interest of the market in PBAT, to date a general overview of the scientific literature which critically explores potentials of PBAT, with focus on design of engineered PBAT/PLA blends, is missing. The present works aims at filling this gap, laying the basis to create a link between fundamental research on PBAT and industrial applications. A general overview of the market and of the state of the art of PBAT based blends is herein provided, focusing on PBAT/PLA blends and possible compatibilization strategies. This work aims to achieve a double target: scientific and social. The scientific target is to summarize the main design criteria used in the conception of engineered plastics based on PBAT blends with PLA, revealing their implementation secrets and strategic aspects. The social target is to develop a useful guide for sector technicians, policy makers and stakeholders to promote the use of biodegradable materials instead of conventional plastics in an even wider range of applications, in order to significantly reduce the environmental impact of plastic products
Prescient Perspectives on Football Tactics: A Case with Liverpool FC, Corners and AI
No full textPrescient (not prescientific) ideas are those that challenge the assumptions that predominate a given field and that typify beforehand the future of that domain. In this short communication, we question how much we are willing to believe that predictive Artificial Intelligence is already able to suggest good prescient ideas on football, for example by hinting the tactical adjustments needed to shoot corner kicks that finally end in goals. We have conducted statistical Chi-squared tests that show that the Liverpool Football Club, in the Premier League seasons 2021/22, 2022/23 and 2023/24, has reached a higher potential for goals from corners with respect to the previous seasons 2016/17, 2017/18 and 2018/19, only in the attacking phase of play (scored goals), but not in the defensive one (conceded goals). This despite a multi-year collaboration between Liverpool FC and authors of [1] on AI, reportedly begun during the season 2020/21. Moreover, no statistically significant difference was found, with another series of Chi-squared tests, between the goals scored/conceded from corner kicks by Liverpool FC and those scored/conceded, in the seasons 2021–24, by Arsenal FC and Manchester City FC. Our study suggests preliminary evidence against the belief that AI is ready to prompt prescient ideas in a dynamic domain, characterized by many multi-agent interactions, like football. Limitations to these results come from the uncertainty on the real nature of the collaboration between Liverpool FC and AI on corner kicks, as discussed at length in the pape
Social capital and its effect on networked firm innovation and competitiveness
Full text linkInternational and local policymakers have repeatedly encouraged the development of clusters -a dense geographic concentration of interconnected businesses- to boost competitiveness at both the firm and regional levels, as well as foster innovation and new product development. Following this trend, many initiatives have started to provide services and infrastructure that can facilitate the establishment of formal and informal ties between firms, local institutions or research centres, as well as upgrade the stock of human and intellectual capital. In this scenario, the present study empirically documents the effects of an innovation network, established by a regional government institution, on the participating firms. In particular, firm-level primary data, derived from the participants of 'Polo di Innovazione ICT - Abruzzo' in Italy, empirically support how the cognitive, structural and relational dimensions of the social capital developed within a cluster initiative affect the performance of participating firms, unveiling a negative moderation effect arising from firms' involvement in the cluster program
FOOTBALL DATA ANALYSIS: THE PREDICTIVE POWER OF EXPECTED GOALS
No full textMajor football events, such as the World Cup, have popularized the European football (i.e., soccer) beyond its traditional geographical borders, for example with a growing number of Americans who have begun to incorporate European football into their daily sport consumption. Many video game series based on this sport have further contributed to this increasing development. Not only that, but many performance indicators inspired by football computer games have become metrics that are now part of the normal conversation about real football, being used to analyse tactics, teams and players. Among these indicators, of prominent importance is the role of expected goals (xG) that measure the quality of a shot by calculating the likelihood that it will be scored from a particular position during a particular phase of play. Often, someone talks about xG leading to imprecise conclusions and to a distorded point of view on this performance indicator. In this paper, using a non-parametrical Kolmogorov Smirnov hypothesis testing method, we show that there is no statistically significant difference if, in a given football tournament, the final scores are awarded to the participating teams either with real goals or based on xGs, thus demystifying some wrong assumptions about this indicator. Data for this study come from all the matches played during the 2020 UEFA European Football Championship
