We survey the literature that has explored the implications of decision-making under ambiguity for financial market outcomes, such as portfolio choice and equilibrium asset prices. This ambiguity literature has led to a number of significant advances in our ability to rationalize empirical features of asset returns and portfolio decisions, such as the failure of the two-fund separation theorem in portfolio decisions, the modest exposure to risky securities observed for a majority of investors, the home equity preference in international portfolio diversification, (...) the excess volatility of asset returns, the equity premium and the risk-free rate puzzles, and the occurrence of trading break-downs.

Giornalista, critico letterario, romanziere e saggista, Maurice Blanchot ha il merito di aver costantemente interrogato il confine incerto tra la parola filosofica e quella della finzione. Lungi dal voler dar peso alle eventuali incoerenze tra i testi e la biografia dell’autore, ci si propone qui di indicare nell’instancabile analisi del nesso tra la propria attività di scrittura e il senso della partecipazione politica, l’angolatura più efficace da cui cogliere la narrazione, teorizzazione e messa in pratica di un’autentica dissoluzione del soggetto.

Die Entwicklung der zeitgenossischen Philosophie ist durch Hegels Denken entscheidend beeinflusst worden. Die Grunde fur seine andauernde Aktualitat aber sind selten verstanden worden. Im Gegensatz zu vielen Hegel-Interpreten wird hier der -absolute Idealismus- als das Wesen der Philosophie Hegels erkannt. Die -dialektische Methode- und das -System- bilden eine untrennbare Einheit. Auf dieser Grundlage erfolgt in einer streng theoretisch-systematischen Perspektive eine konsistente Auslegung von Hegels -Philosophie des unendlichen Selbstbewusstseins-. Einen besonderen Schwerpunkt legt die Arbeit auf die Auseinandersetzung mit dem gegenwartigen amerikanischen (...) Hegelianismus. Ubereinstimmung besteht mit E.E. Harris und R.D. Winfield, wahrend R.B. Brandom entschieden kritisiert wird.<BR> Contemporary philosophy's development has been decisively influenced by Hegel's thought, yet only rarely have the grounds for its everlasting up-to-dateness been understood. Contrary to many Hegel-interpreters, -Absolute Idealism- is here regarded as the core of Hegel's philosophy. The -dialectical method- and the -system- constitute an inseparable unity. On this basis a consistent interpretation of Hegel's -philosophy of infinite self-consciousness- is outlined. Attention is focused especially on the discussion of contemporary American Hegelianism, largely agreeing with E. E. Harris and R. D. Winfield, while sharply criticizing R. B. Brandom.". (shrink)

Farmers’ markets (FMs) represent a crucial player in urban food systems, being the interconnection of local agricultural production and consumption, and serving as spaces for both economic exchange and community building. Despite their transformative potential, there is a scarcity of research that comprehensively investigates the dynamics of FMs network structure and the influence of the actors shaping FMs. The present article delves into the network of relationships within FMs in the Italian city of Bologna. This study adopts the Social Network (...) Analysis (SNA) methodology applied with the Net-Map tool. The research objectives are to visualise the underlying network structure, map the dynamics, and identify the key actors who play pivotal roles in Bologna’s FMs and their level of influence. The research carried out interviews with ten FMs stakeholders, revealing the network of relationships between 54 actors, divided into three categories—civil society, food economy and public administration. Actors were linked by a total of 428 relationships across three types of networks: support, economic, and hindering. Findings indicate a strong support network structure characterised by varying degrees of centrality among different actors. Farmers emerge as a central node due to their pivotal role in providing fresh, local produce. Additionally, local institutions contribute significantly to FMs resilience and growth. Our research demonstrates the importance of recognising the embeddedness of FMs within the local context. By understanding the network structure and influential actors in FMs, policymakers can devise more effective policies for promoting local agriculture, and enhancing the sustainability of urban–rural exchanges. In conclusion, the present study offers valuable insights into the network dynamics of FMs, highlighting their crucial role in the sustainable development of urban and local food systems. (shrink)

In health communication, metaphor can be considered as a reasoning device to let people understand an abstract concept in terms of a concrete one (Lakoff and Johnson 1980; Bowdle and Gentner 2005). Both the positive and negative communicative effects of metaphors have been largely pointed out in a variety of medical fields, from oncology (Semino et al. 2016, 2018) to mental health (Frezza and Zoccolotti 2019). The use of metaphors in vaccine communication has been less considered, though it might be (...) crucial to let people understand vaccination as an important collective health phenomenon. A previous study (Scherer et al. 2015) focused on the communicative effects of conventional metaphors for vaccination, but not specifically on novel metaphors deliberately used to explain the concept of population immunity in vaccination. We hypothesized that metaphors used to explain vaccination as a collective phenomenon could improve the communicative aims of pro-vaccination texts in many respects, ranging from understandability to trust in expertise. We designed a study to test the hypothesis: two groups of participants were presented with a text about vaccination as a collective phenomenon, described in either literal or metaphorical terms. They were asked to evaluate the text on different communicative aspects from both an individual and a collective point of view. The results confirmed the hypothesis that metaphor is an effective reasoning device and that it also enhances the overall communicative effects of the message, in terms of understandability, persuasion, feeling of control over the health situation, trust in expertise, and uptake of experts’ advice. However, the results show that this effect is significantly nuanced in the individual vs. collective response type. (shrink)

This paper studies internal (or intra-)mathematical explanations, namely those proofs of mathematical theorems that seem to explain the theorem they prove. The goal of the paper is a rigorous analysis of these explanations. This will be done in two steps. First, we will show how to move from informal proofs of mathematical theorems to a formal presentation that involves proof trees, together with a decomposition of their elements; secondly we will show that those mathematical proofs that are regarded as having (...) explanatory power all display an increase of conceptual complexity from the assumptions to the conclusion.

Through this contribution I aim to explore the horizons and limits of digital medicine in light of an embodied approach to the issue of care. I will sketch the historical background of digital medicine and show the contemporary status of this interdisciplinary field, as well as its applications and outcomes. Then, I will address a critique of the computational theory of mind (CTM) upon which many contemporary mental health apps are designed. This approach to the mind is inscribed into the (...) modern trend of neuromania, which conceives the embodied, living human being as a mere series of data analyses and algorithms, with the brain as the seat of the person. Drawing on continental philosophy and classical phenomenology I will develop a notion of health conceived as a moral enterprise, showing how wellbeing and vitality are not reducible to a product made by technologies or doctors, but rather they are the results of an embodied encounter. As such, empathy and person-centered care cannot be achieved by digital medicine. They are the result of a journey into the regions of recognition, embodied presence and the aliveness constituting the person. Finally, I will show how the issue of care cannot be separated from an embodied encounter between people, especially in case of dementia. (shrink)

Criminal liability for acts committed by AI systems has recently become a hot legal topic. This paper includes three different contributions. The first contribution is an analysis of the extent to which an AI system can satisfy the requirements for criminal liability: accomplishing an actus reus, having the corresponding mens rea, possessing the cognitive capacities needed for responsibility. The second contribution is a discussion of criminal activity accomplished by an AI entity, with reference to a recent case involving an online (...) bot, the Random Darknet Shopper. This discussion will provide the context for the analysis of commonalities and differences between criminal activities by humans and by artificial systems. The third contribution concerns the evaluation of different ways of addressing criminal activities by AI systems in a regulatory perspective. (shrink)

Metaphor has been considered as a cognitive process, independent of the verbal versus visual mode, through which an unknown conceptual domain is understood in terms of another known conceptual domain. Metaphor might instead be viewed as a cognitive process, dependent on the mode, which leads to genuinely new knowledge via ignorance. First, I argue that there are two main senses of ignorance at stake when we understand a metaphor: we ignore some existing properties of the known domain in the sense (...) that we disregard or neglect them; we ignore some “non-existing” properties of the known domain in the sense that they are not a piece of information belonging to the known domain, but emerge in metaphor interpretation. Secondly, I consider a metaphor as a reasoning device, guiding the interpreters along a path of inferences to a conclusion, which attributes to the target some properties of the source. In this path, interpreters might discover the ignored existing properties of the known domain and/or recover the “non-existing” properties, inferring or imagining the missing piece of information. Finally, I argue that, especially in visual metaphors, this process is guided by a “sentiment of rationality”, tracking a disruption of existing familiar conceptualisations of objects and/or actions and a recovery of ignored properties.

In recent years, bioethical discourse around the topic of ‘genetic enhancement’ has become increasingly politicized. We fear there is too much focus on the semantic question of whether we should call particular practices and emerging bio-technologies such as CRISPR ‘eugenics’, rather than the more important question of how we should view them from the perspective of ethics and policy. Here, we address the question of whether ‘eugenics’ can be defended and how proponents and critics of enhancement should engage with each (...) other. (shrink)

The basis for adoption of pro-environment behaviour is the understanding of causal passages within climate dynamics. The understanding of the causes of climate change is necessary in order _to be able_ to take mitigation actions. Conversely, the understanding of the consequences of climate change is essential in _motivating_ action. The case of ozone depletion confirms this view: the understanding of its causal dynamics played a determining role in people’s behavioural response.

Developmental System Theory is a theoretical reinterpretation of biological phenomena challenging the conventional gene-centered account of development and evolution. In this paper, I focus on Griffiths and Gray’s version of Developmental Systems Theory and I particularly analyze their reconceptualization of inheritance. First, I present their concept of expanded and diffused inheritance; then, I examine and criticize their refusal of the multiple inheritance system model; finally, I present and contrast Griffiths and Gray’s extension of what they call the “causal parity thesis” (...) from development to evolution. I argue that their proposal is an interesting and programmatic philosophical perspective on biological phenomena but, because of their commitment to holism, fails to provide both more heuristic tools for empirical investigation in biology and a more realistic representation of the biological world.

This chapter provides an overview of six topics related to governance, ethical, legal, and social implications of artificial intelligence (AI) for sustainable development goals (SDGs) initiatives. We identified six common challenges and related opportunities to mitigate such challenges, as referred to by the authors analysing the chapters provided in the book The Ethics of Artificial Intelligence for the Sustainable Development Goals. They are (1) governance and collaboration, (2) private investments and the role of big tech companies, (3) AI and communities, (...) (4) AI and individuals, (5) jobs and skills, and (6) impact assessment. (shrink)

"Heidegger [...] è uno di quei filosofi che non si possono solo studiare, ma esigono dal proprio lettore uno sforzo interpretativo che, nella più autentica tradizione ermeneutica è anche partecipazione attiva all'impresa del pensiero [...]. Francesca Brencio [...] si presenta, con questo lavoro, come una mente filosofica che bene coglie lo "spirito del proprio tempo", [...] praticando una storia della filosofia che è ermeneutica rigorosa e al tempo stesso non dogmatica [...]. Brencio sta offrendo il proprio importante contributo, modificando (...) in modo originale un approccio e uno stile tipico della tradizione continentale (in senso lato) e tedesca (in senso stretto), ma rimanendo aperta ad altri contributi".

The aim of this paper is to investigate Nishida Kitarō’s way of philosophizing in the light of the concept of “transition” in order to deepen our understanding of both Nishida’s philosophy and our thinking about and in transitions, using the concept of “boundary” or “border” (Grenze) as a catalyst. For that purpose, we focus on Nishida’s essay “Place” (「場所」), passing through different parts of the text as if through successive gates on a path of transition between one place and the (...) next, until we reach the final place of “absolute nothingness.” Dwelling on this place, we turn our attention to its internal structure and try to depict it along the outlines of a boundary, following the movements taking place in Nishida’s essay. The second part proposes an interpretation of the place of nothingness as an interminable practice of boundary-crossing that doesn’t come to a halt in a final, all-encompassing place, but dynamically situates itself on countless intersecting planes. After a more or less abstract analysis of the concept of “boundary,” we will apply and concretize this approach by using the example of the skin. To this end, we expose five main features of the skin as boundary: permeability, enclosure, excessiveness, interstitiality and reciprocal self-formation. (shrink)
