Research in ethical AI has made strides in quantitative expression of ethical values such as fairness, transparency, and privacy. Here we contribute to this effort by proposing a new family of metrics called “decisional value scores” (DVS). DVSs are scores assigned to a system based on whether the decisions it makes meet or fail to meet a particular standard (either individually, in total, or as a ratio or average over decisions made). Advantages of DVS include greater discrimination capacity between types (...) of ethically relevant decisions and facilitation of ethical comparisons between decisions and decision-making systems, including across different modalities (for instance: human, machine, or coupled human–machine systems). After clarifying ambiguities in the concept of “decision” itself, including the question of how to individuate the decisions made by a system, we discuss the role and meaning of “decision” in common AI and machine learning approaches such as decision trees, neural networks, SVMs, and unsupervised classifiers. We then show how DVSs may be defined for several ethical values of interest, with an extended discussion of transparency. Finally, we explore how such metrics can be applied to real decision-making systems through two case studies: evaluations of LLMs for transparency; and evaluations of criminal risk assessment tools for utility, rights violations, fairness, and transparency.

Financial literacy is becoming a pivotal skill in navigating the marketplaces within the predominant rising digital branches of trading domains; however, there remains a concerning gap in the purchasing behavior of adolescents, who are its primary users. With this in mind, the main objective of our research is to determine whether there is a relationship between a student's level of financial literacy and their online purchase decision-making. The researchers employed an explanatory mixed approach and purposive sampling to identify respondents from (...) Immaculate Conception College of Balayan, Inc. A 5-point Likert scale survey was utilized to collect data from 66 respondents, followed by semi-structured interviews with 10 selected participants. The results showed a moderately positive correlation between a student's financial literacy and online purchase decisions, as determined by the Pearson correlation coefficient. Thus, the thematic analysis revealed that respondents generally have good financial literacy, emphasizing factors like pricing, online reviews, and product ratings when making digital marketplace decisions. However, there are notable gaps in their understanding of basic financial concepts and their ability to apply them in real-life situations. To effectively enhance students’ financial literacy and online purchasing decisions, a holistic approach is necessary, including targeted interventions, practical applications, and continuous adaptation to evolving consumer behaviors. Educational institutions, policymakers, and stakeholders should work together to create comprehensive programs that provide students with the knowledge, skills, and attitudes needed to negotiate real-world financial situations and make sound judgments in the digital commerce ecosystem. By emphasizing practical learning, key financial concepts, and trustbuilding approaches, educators may empower students to become responsible consumers capable of managing their resources successfully and ethically.

The first part of the essay examines the different premises, of Aristotelian and Galenic origin, for the idea of an inherent consumption of the natural heat of every living body, discussing the contributions of Isaac Israeli, Avicenna and Averroes to the reflection on the relationship between the secondary humours (or moistures) and the peculiar category of fevers called ‘hectic’. The second part of the article discusses how the link between moisture, heat and food was taken up and elaborated by Latin (...) Scholastic masters (in particular Thomas Aquinas), and considers the use of the notion of ‘radical moisture’ in the field of theology. Aquinas does not follow the previous theological tradition, originating with Peter Lombard, which denies the possibility that the matter assimilated through food is part of the bodily core that belongs to every human being from birth. The moisture provided by food is, in fact, inseparable from the (radical) moisture that originally belongs to each individual; as such, it is part of the ‘truth of human nature’ (veritas humanae naturae) that will be restored at the moment of the resurrection of the body.

There is no unique and definitive definition of phenomenology. It is rather a method and an experience always open and always renewing itself. Phenomenology involves a change in the "sense of the world": everything acquires its sense and value only when it becomes the content of the lived experience of the subject correlated to his intentional acts. This is the main thesis of the phenomenological method aiming at overcoming the traditional opposition between rationalism and empiricism. Starting from Husserl, the father (...) of this approach, the history of phenomenology undertook different and unexpected developments which in some cases were rather far away from Husserl's original thought. In the U.K. attention has been given to an analytical-epistemological phenomenology focused on the relationship between intentionality and logical semantics. In France it is mainly an anthropological-existential phenomenology. In Germany an hermeneutic phenomenology was developed, mainly by Heidegger and Gadamer. Regardless of these raw distinctions, a big question is so far unresolved: how to reconcile the phenomenological/ existential stance claiming for the irreducibility of each lived experience and the scientific paradigm? Is it possible to imagine brain mechanisms and physiological systems explaining the endless mysteries and manifold paradoxes of the human being? Phenomenology claims that a human being can never be considered as an object, as if he was a natural thing; rather the task is to understand him as the focus of a relationship linking subjective attitudes to the objects showed by the experience. In this sense, an important contribution was Merleau-Ponty's view that man is not something psychic joined to an organism, but a sort of fluctuation of the existence that sometimes is a bodily one, sometimes refers to personal acts. Consequently, he proposes to reinstate in the existence both its "physiological" and "psychic" sides both being intentionally oriented towards a world. (shrink)

The declaration of the COVID-19 pandemic by the World Health Organization on March 11, 2020, led to unprecedented events. All regions of the world participated in implementing preventive health measures such as physical distancing, travel restrictions, self-isolation, quarantines, and facility closures. The pandemic started global disruption of socio-economic systems, covering the postponement or cancellation of public events, supply shortages, schools and universities’ closure, evacuation of foreign citizens, a rise in unemployment and inflation, misinformation, the anti-vaccine movement, and incidents of discrimination (...) toward people affected by or suspected of having coronavirus disease. Attempts have been made to protect the oldest age group at risk, but in many cases, this has led to over-restriction and age discrimination. The rationale for working on the Research Topic "Socio-economic systems in the post-pandemic world: Design thinking, strategic planning, management, and public policy" was the need to start reflecting on resilience and lessons learned from this public health event that revealed the global unpreparedness in critical areas. Also, the pandemic triggered both top-down and bottom-up responses that needed more in-depth analyzes. This Research Topic covers interdisciplinary contributions addressing new thinking, challenges, and transformations required for post-pandemic global, national, regional, and local realities. The presented Research Topic combines studies focused on recognizing the actions and interventions leading to the recovery of socio-economic systems during the tail end and after the pandemic. The studies delivered recommendations regarding, among others, the care of vulnerable, planning socio-economic restart, and imagining the "new normal.". (shrink)

On 11 March 2020, the World Health Organization declared a pandemic of the COVID-19 coronavirus disease that was first recognized in China in late 2019. Among the primary effects caused by the pandemic, there was the dissemination of health preventive measures such as physical distancing, travel restrictions, self-isolation, quarantines, and facility closures. This includes the global disruption of socio-economic systems including the postponement or cancellation of various public events (e.g., sporting, cultural, or religious), supply shortages and fears of the same, (...) schools and universities closure, evacuation of foreign citizens, a rise of unemployment, changes in the international aid schemes, misinformation, and incidents of discrimination toward people affected by or suspected of having the COVID-19 disease. The pandemic has brought to the fore unpreparedness in critical areas that require attention, amid prospects and challenges. Moreover, considerable reorganization efforts are required with implications for assets, resources, norms, and value systems. COVID-19 is challenging the concept of globalization and stimulating responses at the levels of local and regional socio-economic systems that lead to the mobilization of assets that have been unrecognized earlier on, such as various forms of economic capital, social capital, cultural capital, human capital, and creative capital. For example, through digital channels, local groups are forming to create schemes of support for physical and mental wellbeing. These emerging exchanges lead to various social and technological innovations by building on skills and assets that are less important in the free-market economy, such as empathy, skills for crafts, making and fixing; locally grown microgreens; and micromanufacturing. Isolation and local living are also making it much harder to ignore the civic responsibilities towards communities, meant as individuals, vulnerable groups, and local businesses. Whilst the pandemic is limiting physical participation, this challenging time is uncovering alternative ways of mutual support, which may create long-term benefits for socio-economic systems, including environmental and biodiversity protection, reduction of the air pollution, and climate action. The pandemic’s threat to public health will hopefully be overcome with implications for disruption for an extended period that we are unable to forecast at this stage. It is key to focus on studies recognizing the activities and interventions leading to the recovery of socio-economic systems after the pandemic. Reflecting and planning on how societies and economies will go back to “business as usual” requires new forms of communication and cooperation, imaginative design thinking, new styles of management, as well as new tools and forms of participation in various public policies. Many questions related to the care of the vulnerable, economic restart, and the risk of future pandemics, to mention but a few, are already occupying the academic, scientific, experts, and activist communities, who have started to imagine the “new normal.”.

A recent study by Castellani et al. (JAMA 302(23):2573–2579, 2009) describes the population-level effects of the choices of individuals who underwent molecular carrier screening for cystic fibrosis (CF) in Veneto, in the northeastern part of Italy, between 1993 and 2007. We discuss some of the ethical issues raised by the policies and individual choices that are the subject of this study. In particular, (1) we discuss the ethical issues raised by the acquisition of genetic information through antenatal carrier testing; (2) (...) we consider whether by choosing to procreate naturally these couples can harm the resulting child and/or other members of society, and what the moral implications of such harm would be; (3) we consider whether by choosing to avoid natural procreation carrier couples can harm current or future individuals affected by cystic fibrosis; (4) we discuss whether programs that make carrier testing available can be considered eugenic programs.

This is a collection of essays that all appeared in various Italian academic journals in the late seventies, aimed at tackling what we then used to call the " Crisis of Marxism". The reason of interest of these essays is the attitude taken by the author, who does not want to be neither that of the refugees from Marxism, who talk about something else, neither that of those who continue "to call themselves Marxists while ignoring the thousand reasons for doubt".

È una credenza diffusa che i marchi di origine (DOCG, DOC, DOP, IGT, IGP e PAT, rispettivamente: di origine controllata e garantita; di origine controllata; di origine protetta; indicazione geografica tipica; indicazione geografica protetta; prodotti agroalimentari tradizionali) siano di grande utilità sia per i consumatori che per i produttori: certificando l’origine e il metodo di produzione di un prodotto, essi ne garantiscono una certa qualità di fronte al consumatore. Ma è proprio così? Che cosa giustifica l’introduzione di un marchio di (...) origine? Quanto sostengo qui di seguito è che, sebbene non credo si possa negare che i marchi di origine segnalino anche una certa qualità di un prodotto, forse non sono il modo migliore per farlo. Di fatto, per il consumatore, i marchi non garantiscono niente che vada oltre alla qualità richiesta affinché la certificazione venga rilasciata; ma, al contempo, in quanto forme di protezionismo, favoriscono certi produttori, prevenendo l’utilizzo della denominazione a chi offre un prodotto di qualità analoga o superiore, ma provienente da una zona priva di tradizioni. In altre parole: se vi sono prodotti equiparabili per qualità e gusto ad un dato prodotto di origine, e possibilmente più economicamente vantaggiosi, il consumatore non avrà modo di accorgersene dalla sola nomenclatura. Quindi: i marchi di origine sono (talvolta) un ostacolo all’acquisto e al godimento dei prodotti migliori al miglior prezzo. Talvolta: questo deve essere ben sottolineato, poiché in certi casi (per esempio quello dei PAT) il prodotto certificato dal marchio ha un mercato talmente di nicchia da costituire un tuttuno tra qualità e origine. (Si potrebbe aggiungere che le certificazioni dei marchi non sono sempre ottenute attraverso procedure affidabili. Non insisterò oltre su questo punto, per il quale si rimanda a: Paolo Conti, La leggenda del buon cibo italiano e altri miti alimentari contemporanei, Fazi Editore, 2006; Peter Singer e Jim Mason: The Way We Eat..

Female crested gibbons (genus Nomascus) perform conspicuous sequences of twitching movements involving the rump and extremities. However, these dances have attracted little scientific attention and their structure and meaning remain largely obscure. Here we analyse close-range video recordings of captive crested gibbons, extracting descriptions of dance in four species (N. annamensis, N. gabriellae, N. leucogenys and N. siki). In addition, we report results from a survey amongst relevant professionals clarifying behavioural contexts of dance in captive and wild crested gibbons. Our (...) results demonstrate that dances in Nomascus represent a common and intentional form of visual communication restricted to sexually mature females. Whilst primarily used as a proceptive signal to solicit copulation, dances occur in a wide range of contexts related to arousal and/or frustration in captivity. A linguistically informed view of this sequential behaviour demonstrates that movement within dances is organized in groups and follows an isochronous rhythm — patterns not described for visual displays in other non-human primates. We argue that applying the concept of dance to gibbons allows us to expand our understanding of communication in non-human primates and to develop hypotheses on the rules and regularities characterising it. We propose that crested gibbon dances likely evolved from less elaborate rhythmic proceptive signals, similar to those found in siamangs. Although dance displays in humans and crested gibbons share a number of key characteristics, they cannot be assumed to be homologous. Nevertheless, gibbon dances represent a striking model behaviour to investigate the use of complex gestural signals in hominoid primates. (shrink)

RESUMO A Transferência de Embrião (TE) em bovinos se trata de uma técnica mundialmente disseminada com objetivo de aumentar a capacidade reprodutiva da fêmea. Mantém vínculo direto com outras técnicas das biotecnologias da reprodução, como, a Ovum Pick-Up (OPU), Produção In Vitro e In Vivo de embriões (PIVE) e Transferência de Embrião em Tempo Fixo (TETF), sendo estas, técnicas que fazem parte de um processo, que vai desde a seleção de doadoras, passando pelo preparo dos embriões até sua inovulação em (...) receptoras criteriosamente selecionadas. Com seu avanço, várias tecnologias de manejo vêm sendo implantadas: formas no transporte de embriões, protocolos de sincronização de doadoras e receptoras, e protocolos de recuperação de oócitos para produção de embriões. Isto infundiu a tecnologia, porém, os investimentos previstos para a produção de um animal de alto mérito genético limita sua utilização. Contudo, esta análise abordou avanços tecnológicos essenciais para o sucesso da TE, incluindo novos protocolos, sexagem de embriões, além do uso de embriões congelados Direct Transfer (DT) e vitrificados. No entanto, é claro que o sucesso do procedimento está no processo como um todo, em destaque ressalta-se que é de grande valia que o profissional apto a executar a técnica esteja sempre preparado e atualizado garantindo qualidade, eficiência e sustentabilidade na pecuária. Esta revisão foi desenvolvida com o propósito de adquirir conhecimento teórico, de forma detalhada e crítica, nas técnicas e procedimentos de Transferência de Embriões em bovinos, incluindo a colheita, manipulação e implantação de embriões. Palavras-chaves: Bovino, doadora, embrião, receptora. ABSTRACT Embryo Transfer (ET) in cattle is a globally widespread technique aimed at enhancing the reproductive capacity of females. It is closely linked to other techniques in reproductive biotechnologies, such as Ovum Pick-Up (OPU), In Vitro and In Vivo Embryo Production (PIVE), and Timed Embryo Transfer (TET), all of which are part of a process that ranges from donor selection, through embryo preparation, to their inoculation into carefully chosen recipients. With its advancement, various management technologies have been implemented: including methods for embryo transport, synchronization protocols for donors and recipients, and oocyte recovery protocols for embryo production. Although technology has been infused, the anticipated investments for producing animals of high genetic merit limit its widespread use. However, this analysis addressed essential technological advances for the success of ET, including new protocols, embryo sexing, as well as the use of frozen-thawed (DT) and vitrified embryos. Nevertheless, it is clear that the success of the procedure lies in the entire process. Notably, it emphasizes the significant value of having a qualified professional who is always prepared and updated to ensure quality, efficiency, and sustainability in livestock farming. This literary review was developed with the purpose of acquiring theoretical knowledge, in a detailed and critical way, on the techniques and procedures of Embryo Transfer in cattle, including the collection, manipulation and implantation of embryos.

In the paper “Math Anxiety,” Aden Evens explores the manner by means of which concepts are implicated in the problematic Idea according to the philosophy of Gilles Deleuze. The example that Evens draws from Difference and Repetition in order to demonstrate this relation is a mathematics problem, the elements of which are the differentials of the differential calculus. What I would like to offer in the present paper is an historical account of the mathematical problematic that Deleuze deploys in his (...) philosophy, and an introduction to the role that this problematic plays in the develop- ment of his philosophy of difference. One of the points of departure that I will take from the Evens paper is the theme of “power series.”2 This will involve a detailed elaboration of the mechanism by means of which power series operate in the differential calculus deployed by Deleuze in Difference and Repetition. Deleuze actually constructs an alternative history of mathematics that establishes an historical conti- nuity between the differential point of view of the infinitesimal calculus and modern theories of the differential calculus. It is in relation to the differential point of view of the infinitesimal calculus that Deleuze determines a differential logic which he deploys, in the form of a logic of different/ciation, in the development of his proj- ect of constructing a philosophy of difference.
