Network analysis views complex systems as networks with well-defined structural properties that account for their complexity. These characteristics, which include scale-free behavior, small worlds and communities, are not to be found in networks such as random graphs and lattices that do not correspond to complex systems. They provide therefore a robust ground for claiming the existence of “complex networks” as a non-trivial subset of networks. The theory of complex networks has thus been successful in making systematically explicit relevant marks of (...) complexity in the form of structural properties, and this success is at the root of its current popularity. Much less systematic has been, on the other hand, the definition of the properties of the building components of complex networks. The obvious assumption is that these components must be nodes and links. Generally, however, the internal structure of nodes is not taken into account, and links are serendipitously identified by the perspective with which one looks at the network to be analyzed. For instance, if the nodes are Web pages that contain information about scientific papers, one point of view will match the relevant links with hyperlinks to similar Web pages, and another with citations of other articles. We intend to contribute here a systematic approach to the identification of the components of a complex network that is based on information theory. The approach hinges on some recent results arising from the convergence between the theory of complex networks and probabilistic techniques for content mining. At its core there is the idea that nodes in a complex network correspond to basic information units from which links are extracted via methods of machine learning. Hence the links themselves are viewed as emergent properties, similarly to the broader structural properties mentioned above. Indeed, beside rounding up the theory, this approach based on learning has clear practical benefits, in that it makes networks emerge from arbitrary information domains. We provide examples and applications in a variety of contexts, starting from an information-theoretic reconstruction of the well-known distinction between “strong links” and “weak links” and then delving into specific applications such as business process management and analysis of policy making.

The history of science is increasingly directing its attention to the diachronic examination of women's involvement within spaces dedicated to scientific inquiry. While this field of study boasts rich and meticulous historiography, delving into the sixteenth century leaves the impression of encountering either a noticeable absence of women in the realm of natural history or an underexplored period in this regard. Undoubtedly, within the Italian context of the time, the cultural milieu shaped by the Counter-Reformation further heightened the social challenges (...) faced by women.Notwithstanding these challenges, a noteworthy female figure emerges in the latter half of the sixteenth century – Francesca Fontana, the second wife of the natural history scholar Ulisse Aldrovandi (1522–1605). From an overall view of the sources, Fontana seems to assume a pivotal role in the realization of collections and works attributed to the eminent naturalist. This study aims to delineate the role played by Fontana within Aldrovandi's ‘officina naturale.’ By examining the available documents in a chronological order, my aim is to provide insights into the evolution of her education and her practical and technical skills, harnessed in the pursuit of her husband's enterprises and scholarly contributions.

Function talk is a constant across different life sciences. From macro-evolution to genetics, functions are mentioned everywhere. For example, a limb’s function is to allow movement and RNA polymerases’ function is to transcribe DNA. Biochemistry is not immune from such a characterization; the biochemical world seems to be a chemical world embedded within biological processes. Specifically, biochemists commonly ascribe functions to biomolecules and classify them accordingly. This has been noticed in the recent philosophical literature on biochemical kinds. But while a (...) lot has been written on biological and psychological functions, little has been said explicitly about biochemical fuctions. Here, I explore functional attribution to biochemical molecules. I argue that if we accept this attribution, then biochemical functions are constituted by chemical dispositional properties that causally contribute to selected biological processes. In section 2, I discuss the controversy concerning the characterization of biochemical functions. In section 3, I consider whether a biological or a chemical under- standing of function can be applied to biochemical functions, illustrating the account with the example of vitamin B12. The result is that none of the theories on their own provides an adequate characterization. In section 4, I present an account of biochemical functions. In section 5, I assess this account taking into consideration common requirements for a theory of functions and an objection. (shrink)

This book presents a unique rethinking of G. W. F. Hegel's philosophy from unusual and controversial perspectives in order to liberate new energies from his philosophy. The role Hegel ascribes to women in the shaping of society and family, the reconstruction of his anthropological and psychological perspective, his approach to human nature, the relationship between mental illness and social disease, the role of the unconscious, and the relevance of intercultural and interreligious pathways: All these themes reveal new and inspiring aspects (...) of Hegel’s thought for our time.

In everyday conversation, messages are often communicated indirectly, implicitly. Why do we seem to communicate so inefficiently? How speakers choose to express a message (modulating confidence, using less explicit formulations) has been proposed to impact how committed they will appear to be to its content. This commitment can be assessed in terms of accountability – is the speaker held accountable for what they communicated? – and deniability – can the speaker plausibly deny they intended to communicate it? We investigated two (...) factors that may influence commitment to implicitly conveyed messages. In a preregistered online study, we tested the hypothesis that the degree of meaning strength (strongly or weakly communicated) and the level of meaning used by the speaker (an enrichment or a conversational implicature) modulate accountability and plausible deniability. Our results show that both meaning strength and level of meaning influence speaker accountability and plausible deniability. Participants perceived enrichments to be harder to deny than conversational implicatures, and strongly implied content as more difficult to deny than weakly implied content. Furthermore, participants held the speaker more accountable to content conveyed via an enrichment than to content conveyed via an implicature. These results corroborate previously found differences between levels of meaning (enrichment vs. implicature). They also highlight the largely understudied role of meaning strength as a cue to speaker commitment in communication. (shrink)

The present thesis explores some metaphysical issues concerning biochemical kinds and the relations between chemical and biological properties and phenomena. The main result of this thesis is that there is something sui generis about biochemical kinds. This result is motivated by two theoretical steps. The first is characterising biochemical functions as weakly emergent from the chemical structure [Chapter 3, Chapter 6]. The second is via an account for which biochemical kinds are natural categories [Chapter 4, Chapter 7]. The thesis comprises (...) four parts. Part I [Chapter 1, Chapter 2] aims to offer the methodological and conceptual tools that underpin this research. Chapter 1 presents the debate on the unity of science and the motivation of the research. Chapter 2 presents the account of natural kinds that will be used throughout the thesis. Part II [Chapter 3, Chapter 4] offers a detailed metaphysical analysis of the molecular gene. Chapter 3 argues that molecular genes are weakly emergent from nucleic acids. Chapter 4 argues that the category "molecular gene" can be deemed a natural kind, following the account presented in Chapter 2. Part III [Chapter 5, Chapter 6, Chapter 7] explores some of the themes related to biochemical kinds and generalises some of the results from Part II. Chapter 5 considers biochemical functions and how functional attribution should be interpreted for biochemical molecules. Chapter 6 considers the relation between biochemical functions and structure, spelt in terms of weak emergence and explores unity in biochemistry. Chapter 7 considers the topic of biochemical kinds per se and argues that biochemical kinds are natural categories. Part IV [Chapter 8] elucidates the main outcome and the implications that this research can have for future discussion in the philosophy and metaphysics of biochemistry and the unity of science.

Aristote estime qu’une vie consacrée à gagner de l’argent ne mérite pas d’être vécue, dans la mesure où elle est sujette à des contraintes et fondée sur une conception pervertie de la richesse. Cependant, il assigne à l’argent une valeur instrumentale en tant qu’il est indispensable au bonheur, et il reconnaît qu’il y a des tendances naturelles à la richesse en tout agent. Cet article se propose de clarifier les thèses d’Aristote concernant la fonction de la richesse dans son rapport (...) à une vie bonne, concernant ce qui garantit l’usage correct des biens et comment il est possible de promouvoir la pratique de la chrématistique naturelle face à l’extension des formes perverties de recherche du profit. L’article entend ensuite montrer quelles vertus sont liées à la richesse – générosité, magnificence et justice ou équité – et comment elles se rattachent aux vices opposés – c’est-à-dire : prodigalité et avarice, tendance dépensière et pingrerie, et injustice ou inéquité. L’intention de cette étude est d’expliquer pourquoi l’enquête aristotélicienne sur les bonnes et mauvaises habitudes liées à l’usage de la richesse est complémentaire de l’enquête sur la genèse des phénomènes économiques, et pourquoi elle vise à garantir dans la pratique une chrématistique parfaitement intégrée à l’éthique et à la politique.

People often deny having meant what the audience understood. Such denials occur in both interpersonal and institutional contexts, such as in political discourse, the interpretation of laws and the perception of lies. In practice, denials have a wide range of possible effects on the audience, such as conversational repair, reinterpretation of the original utterance, moral judgements about the speaker, and rejection of the denial. When are these different reactions triggered? What factors make denials credible? There are surprisingly few experimental studies (...) directly targeting such questions. Here, we present two pre-registered experiments focusing on (i) the speaker’s incentives to mislead their audience, and (ii) the impact of speaker denials on audiences’ moral and epistemic assessments of what has been said. We find that the extent to which speakers are judged responsible for the audience’s interpretations is modulated by their (the speakers’) incentives to mislead, but not by denials themselves. We also find that people are more willing than we expected to revise their interpretation of the speaker’s utterance when they learn that the ascribed meaning is false, regardless of whether the speaker is known to have had incentives to deceive their audience. In general, these findings are consistent with the idea that communicators are held responsible for the cognitive effects they trigger in their audience; rather than being responsible for, more narrowly, only the effects of what was “literally” said. In light of our findings, we present a new, cognitive analysis of how audiences react to denials, drawing in particular on the Relevance Theory approach to communication. We distinguish in particular: (a) the spontaneous and intuitive re-interpretation of the original utterance in light of a denial; (b) the attribution of responsibility to the speaker for the cognitive effects of what is communicated; and (c) the reflective attribution of a particular intention to the speaker, which include argumentative considerations, higher-order deniability, and reputational concerns. Existing experimental work, including our own, aims mostly at (a) and (b), and does not adequately control for (c). Deeper understanding of what can be credibly denied will be hindered unless and until this methodological problem is resolved. (shrink)

The aim of this article is to investigate around the life in the contemporary society, characterized by risks and catastrophes. What does mean to live fearing that in any moment a catastrophe could happen (a tsunami, an earthquake, a nuclear explosion)? Despite of the failure of science and public institutions in the prevention of the catastrophes, the question is the following: Can we use the catastrophe as a paradigm of the contemporary uncertain life, trying to mean it as a theme (...) of mediation? Can we use the catastrophe for developing a philosophy of the recognition of the other who has been involved in the same tragedy? (shrink)

What is a gene? Does it represent a natural kind, or is it just a tool for genomics? A clear answer to these questions has been challenged by postgenomic discoveries. In response, I will argue that the gene can be deemed a natural kind as it satisfies some requirements for genuine kindhood. Specifically, natural kinds are projectible categories in our best scientific theories, and they represent nodes in the causal network of the world (as in Khalidi. Natural Categories and Human (...) Kinds: Classification in the Natural and Social Sciences. Cambridge University Press, Cambridge, 2013; Khalidi. Synthese 195: 1379–1396, 2018; Khalidi.

In Sect. 2, I will present a brief history of the gene and the controversy over its status. In Sect. 3, I will introduce the account of natural kinds considered in this paper. In Sect. 4, I will first present the relevant definition of genes and how they can be classified. Then, I will argue that the gene can be considered a natural kind as it satisfies the criteria for natural kindhood. Section 5 concludes. (shrink)

Prosocial organizations represent key actors in the quest to promote positive change, foster social impact, and revitalize cities. Notwithstanding their importance in tackling the increasing challenges threatening our society (e.g., pollution, socio-economic inequalities), these actors may not be perceived as salient in the eyes of different stakeholders, and thus their work may be jeopardized by multiple forms of resistance. Scant attention in research has been devoted to understand how prosocial organizations may acquire saliency and navigate these forms of resistance while (...) pursuing urban revitalization. We address this gap by engaging in a qualitative investigation of a Sicilian cultural center. We found that the prosocial organization in our study could navigate different occurrences of resistance and acquire saliency by enacting mechanisms that leveraged the engagement of supporting stakeholders and the idiosyncratic characteristics of place. Our study contributes to the literature about urban revitalization, prosocial organizations, and stakeholder theory—while also complementing research investigating the role of place in management.

In this paper, we will explore the relation between molecular structure and functions displayed by biochemical molecules in complex physiological processes by using tools from the philosophy of science and the philosophy of scientific practice. We will argue that biochemical functions are weakly emergent from molecular structure by using an account of weak. In order to explore this thesis, we will consider the role of vitamin B12 in contributing to the process of erythropoiesis. The structure of the paper is the (...) following: First, we will consider biochemical functions and why they cannot be easily reduced to their chemical realisers. We will suggest weak emergence as an alternative while also accounting for the relevance of the context, in our case, systemic and organisational. The paper will conclude by considering (1) how the usage of tools from the philosophy of science, such as weak emergence, can aid our understanding of the relations between the components of complex phenomena, such as erythropoiesis, and (2) how the philosophy of scientific practice sheds light on the explanatory role of processes that are dynamically stabilised and the different levels of organisation implied.

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)

Understanding when it is acceptable to interrupt a joint activity is an important part of understanding what cooperation entails. Philosophical analyses have suggested that we should release our partner from a joint activity anytime the activity conflicts with fulfilling a moral obligation. To probe young children’s understanding of this aspect, we investigated whether 3-year-old children (N = 60) are sensitive to the legitimacy of motives (selfish condition vs. moral condition) leading agents to intentionally interrupt their joint activity. We measured whether (...) children protested or released their partner by scoring their reactions. Our results indicate that children did not manifest different reactions when the motive behind their partner leaving was moral than when the motive was selfish. However, our data showed a stable pattern: regardless of the partner’s motives, some 3-year-olds take initiatives to release their partners from joint activity, suggesting that measuring release is a valuable tool for investigating joint action. -/- .

_Abstract_: The overarching aim of this paper is to provide a comprehensive account of melancholic depression from the perspective of hermeneutic phenomenology. More specifically, we propose that this condition should be interpreted as an alteration in the intentional arc that affects corporeality, temporality, and spatiality, rather than as a mood disorder. In fact, classifying melancholic depression as a mood disorder seems a particularly poor choice; the mood disorder is not a cause but a consequence of a primary disturbance in operative (...) intentionality. Our paper comprises four sections: (1) We provide a methodological and conceptual framework for our theoretical work, adopting a hermeneutic phenomenological perspective on melancholic depression, and underlining the main differences between melancholia and depression. (2) We offer a detailed reconstruction of the different interpretations of melancholic depression and their relationships to the issue of temporality. (3) We analyze the disruption of intentionality in melancholic depression and how it affects corporeality and directionality. (4) We focus on the disruption of moods and affects in melancholic depression, observing how they shape subjective experience. The goal of this theoretical contribution is to underscore the role of operative intentionality and its disruptions in melancholic depression. We argue that taking elements such as intentionality, embodiment, and spatiality into consideration could help to direct therapies along more promising paths. _Keywords_: Melancholic Depression; Operative Intentionality; Corporeality; Directionality; Temporality; Mood Disorders _La depressione melancolica. Un’interpretazione fenomenologico-ermeneutica_ _Riassunto_: L’intento generale di questo contributo è di fornire un’interpretazione della depressione melancolica attraverso la fenomenologia ermeneutica. Più specificatamente, la nostra ipotesi è che questa condizione potrebbe essere interpretata come un’alterazione dell’arco intenzionale la quale impatta la corporeità, la temporalità e la spazialità, e non come un disordine dell’umore. Infatti, classificare la depressione melancolica come un disordine dell’umore ci sembra una scelta particolarmente limitata; il disordine dell’umore non è la causa ma la conseguenza di un disturbo a livello primario dell’intenzionalità operativa. Il nostro contributo si articola in quattro sezioni: nella prima, forniamo una cornice metodologica e concettuale finalizzata a chiarificare le fondamenta teoretiche del nostro lavoro, ad illustrare l’utilizzo della fenomenologia ermeneutica in riferimento alla depressione melancolica, e a sottolineare le differenze principali tra melancolia e depressione. Nella seconda sezione, ricostruiamo in modo dettagliato le diverse interpretazioni della depressione melancolica e la loro relazione con la temporalità. Nella terza sezione, analizziamo l’alterazione dell’intenzionalità nella depressione melancolica e come essa impatti sia la corporeità che la direzionalità. Infine, nell’ultima sezione ci concentriamo sull’alterazione degli stati umorali e della componente affettiva, osservando come questi elementi vadano a caratterizzare l’esperienza soggettiva. Il fine di questo contributo teoretico è di evidenziare il ruolo dell’intenzionalità operativa e delle sue alterazioni nella depressione melancolica. La nostra tesi è che prendere in considerazione alcuni elementi, come l’intenzionalità, l’embodiment e la spazialità, possa contribuire a delineare interventi terapeutici in modo più promettente. _Parole chiave_: Depressione melancolica; Intenzionalità operativa; Corporeità; Direzionalità; Temporalità; Disturbi dell’umore.

The exceptional pandemic due to the 2019 coronavirus disease (COVID-19) has obliged all Italians to stay at home. In the literature, there are evidences that traumatic global events, such as natural catastrophes and pandemic, have negative effects on the physical and psychological health of the population. We carried out a survey to analyze the physical and psychological conditions of Italians during the pandemic. Due to the severe limitations in moving during the phase one lockdown, the survey was administered by internet. (...) Results show that Italians followed the provisions established by the Italian government to avoid contamination, but 43% of them declared to have suffered from physical symptoms, in particular migraine, sleep disorders, persistent exhaustion, and difficulty of concentration. They have great fear to be contaminated or that relatives or friends can be contaminated, and they actively take actions to avoid contamination. Participants declared that they had suffered a lot of inconveniences due to restrictions in their movements, and that their life habits were strongly changed. They spent their time at home in different activities, but their psychological well-being was strongly impaired by the lockdown. The level of anxiety tripled, in relation to the prepandemic period, and 30% of males and 41% of females declared to have severe levels of depression. Participants with high levels of optimism and hopefulness show a stronger resilience against anxiety and depression. In addition, there is a negative correlation between anxiety and depression and the five factors of personality. These results show that psychological diseases must not be neglected, and that people in lockdown do need support for their psychological health, also with the help of internet and communication technologies.

Gendered socialization has prompted numerous attempts to redefine what counts as an autonomous choice. However, there is strong disagreement among feminist theorists over the criteria to identify cases of autonomy impairment _vis-à-vis_ the embeddedness of individuals in patriarchal cultures. I argue that this focus on choice and autonomy has often neglected the costs of non-compliance to social norms and the trade-offs that women make to flourish within their community. Even if we were to find an effective way to determine whether (...) a self-regarding choice calls for state interference because of its socialized nature, we would still lack a sufficient justification for interfering with women’s choices. To justify political action, my claim is that we should also look at the effects that preference interference would have on women within their societal context. Consequently, I develop a non-ideal feminist account aimed chiefly at analysing the costs of proposed feminist change. I shall focus in particular on women’s engagement with practices of body modification for the sake of conforming to gendered standards of appearance, such as cosmetic surgery and hymen restoration. In both cases, I argue that blanket bans risk backfiring into a form of double-jeopardy for those who are already the most vulnerable to gendered oppression, hence they are not justified. However, this does not imply passively accepting the status quo but urges us to reconsider new ways to offset transition costs, making resistance to social norms a collectively shared endeavour rather than a burden that exclusively befalls the most vulnerable.

This paper seeks to unveil and investigate the close bond existing between the critical project developed by Axel Honneth and Hans Joas in Social Action and Human Nature (1980) and John Dewey’s naturalistic humanism and social criticism. I will contend that these authors develop an original and compelling approach to the critique of the social world, which relies on a naturalistic redefinition of human beings with intersubjective premises. By reconsidering human beings in their continuity and discontinuity with nature, they attempt (...) to identify the specific quality of human action with respect to animal behavior and to employ this category as a criterion for the critique of the social world. On the other hand, the paper will underline how Dewey significantly contributes to the outlining of a contemporary critical project with naturalistic premises. Indeed, his naturalistic humanism provides a systematic metaphysics of human experience to ground social criticism, wherein the underdeveloped elements of Social Action and Human Nature’s analysis of human action are better explained and justified from a theoretical point of view.

This article draws attention to the ethical complexity researchers may be confronted with during fieldwork should an adult participant with intellectual disabilities disclose that harm or an illegal activity is occurring or has occurred in the past. The need to gain ethical approval and the positioning of people with intellectual disabilities as vulnerable within ethics review procedures can result in the adoption of paternalistic approaches as researchers are encouraged to break confidentiality to report concerns to other professionals. Whilst this may (...) fulfil a researcher’s duty to ensure no harm occurs to participants, if it takes place against the participant’s wishes it may also violate participant autonomy, reinforce unequal relations of power, and may unwittingly contribute to subsequent harm occurring. Whilst the article begins from our experience as two UK-based researchers working with people with intellectual disabilities, it draws on existing literature and guidelines to expose the ethical tensions which may be encountered. It is intended that the paper acts as a starting point for researchers wishing to reflect on their practice and ethical decision-making, whilst contributing to wider debates on the position of people with intellectual disabilities within society.

Central to the legal positivism of the nineteenth and the first half of the twentieth century was the dogma of the Ideal Legislator. Legal materials were to be interpreted as the work of an omniscient, coherent, consistent legislator. We argue that this dogma persists in the different guise of the competent speaker model, on which legal materials are the work of a competent speaker, who follows all the pertinent semantic and pragmatic rules. We will first lay out the Ideal Legislator (...) dogma as applied in legal interpretation, arguing that this dogma does not limit interpretive discretion but rather amplifies it by hiding it under the veil of an inexistent, purely instrumental rationality. We will then turn to the competent speaker model, showing that, despite its apparent neutrality, it proves to be a reincarnation of the Ideal Legislator dogma, for it, too, amplifies interpretive discretion, only it hides it under the veil of an inexistent, purely linguistic rationality. Finally, we will inquire into the different types of rationality and their relations, arguing that there is always a choice and value judgment involved in ascribing rationality to legislators, and that these choices and judgments need to be carefully inspected and normatively justified.

This paper aims to develop a better understanding of the influence of the social environment in which entrepreneurs reside on the success of the crowdfunding projects they propose. Specifically, this study investigates on the importance of local religiosity on the propensity to support cross-regional crowdfunding projects. We theoretically discuss and empirically document, using a dataset of 5841 contributions on three Swiss reward-based and donation-based platforms, that local religiosity affects cross-regional resource flows by creating social interactions and enhancing trust. Furthermore, we (...) find that cross-regional resource flows are more likely between regions sharing the same primary religion—whether Protestant or Catholic. (shrink)

BackgroundNeuroimaging studies have shown a complex pattern of brain activation during perception of a pleasant odor and during its olfactory imagery. To date, little is known regarding changes in motor cortex excitability during these tasks. Bergamot essential oil is extensively used in perfumes and cosmetics for its pleasantness. Therefore, to further our understanding of the human sense of smell, this study aimed to investigate the effect of perception and imagery of a pleasant odor on motor cortex using Transcranial magnetic stimulation.Materials (...) and MethodsWe examined the primary motor cortex excitability during perception of a pleasant odor or perception of odorless saline. Furthermore, we tested the effect of olfactory imagery of BEO on corticospinal excitability. The increase in motor evoked potential amplitude was correlated with personality dimensions scores, pleasantness, vividness, and general imagery ability.ResultsThe results indicate that the corticospinal excitability changed after both perception and imagery of a pleasant odor. The correlation analysis shows an association with neuroticism personality trait and with general olfactory imagery ability.ConclusionBoth perception of a pleasant odor and its olfactory imagery modulate motor cortex excitability. The enhanced brain activation is affected by specific individual characteristics. Overall, our findings provide physiological evidence for a complex interaction between the olfactory and motor systems. (shrink)
