We design an experiment to study investment behavior in different repeated contest settings, varying the uncertainty of the outcomes and the number of participants in contests. We find decreasing over-expenditures and a higher rate of ‘dropout’ in contests with high uncertainty over outcomes, while we detect a quick convergence toward equilibrium predictions and a near to full participation when this type of uncertainty vanishes. These results are robust to changes in the number of contestants. A learning parameter estimation using the (...) experience-weighted attraction model suggests that subjects adopt different learning modes across different contest structures and helps to explain expenditure patterns deviating from theoretical predictions.

Complex systems can be characterized by classes of equivalency of their elements defined according to system specific rules. We propose a generalized preferential attachment model to describe the class size distribution. The model postulates preferential growth of the existing classes and the steady influx of new classes. According to the model, the distribution changes from a pure exponential form for zero influx of new classes to a power law with an exponential cut-off form when the influx of new classes is (...) substantial. Predictions of the model are tested through the analysis of a unique industrial database, which covers both elementary units (products) and classes (markets, firms) in a given industry (pharmaceuticals), covering the entire size distribution. The model's predictions are in good agreement with the data. The paper sheds light on the emergence of the exponent tau approximately 2 observed as a universal feature of many biological, social and economic problems. (shrink)

This chapter examines the real status of the scientific theory of evolution and what people mean by intelligent design. More generally, it explores the proper relationship between science and religion, not to mention politics, in early 21st century America. These concepts are examined through the inquiring minds and sharp tongues of Jon Stewart, Lewis Black of the “Evolution, Schmevolution” series, and former Daily Show “correspondent” Ed Helms.

Human brain organoids (HBOs) are three-dimensional biological entities grown in the laboratory in order to recapitulate the structure and functions of the adult human brain. They can be taken to be novel living entities for their specific features and uses. As a contribution to the ongoing discussion on the use of HBOs, the authors identify three sets of reasons for moral concern. The first set of reasons regards the potential emergence of sentience/consciousness in HBOs that would endow them with a (...) moral status whose perimeter should be established. The second set of moral concerns has to do with an analogy with artificial womb technology. The technical realization of processes that are typically connected to the physiology of the human body can create a manipulatory and instrumental attitude that can undermine the protection of what is human. The third set concerns the new frontiers of biocomputing and the creation of chimeras. As far as the new frontier of organoid intelligence is concerned, it is the close relationship of humans with new interfaces having biological components capable of mimicking memory and cognition that raises ethical issues. As far as chimeras are concerned, it is the humanization of nonhuman animals that is worthy of close moral scrutiny. A detailed description of these ethical issues is provided to contribute to the construction of a regulative framework that can guide decisions when considering research in the field of HBOs.

The interview reconstructs Jeffrey Schnapp's brilliant career from his origins as a scholar of Dante and the Middle Ages to his current multiple interdisciplinary interests. Among other things, Schnapp deals with knowledge design, media history and theory, history of the book, the future of archives, museums, and libraries. The main themes of the interview concern the relationships between technology and pedagogy, the future of reading, and artificial intelligence.

While “meaning negotiation” has become an ubiquitous term, its use is often confusing. A negotiation problem implies not only a convenience to agree, but also diverging interest on what to agree upon. It implies agreement but also the possibility of disagreement. In this chapter, we look at meaning negotiation as the process through which agents starting from different preferred conceptual representations of an object, an event or a more complex entity, converge to an agreement through some communication medium. We shortly (...) sketch the outline of a geometric view of meaning negotiation, based on conceptual spaces. We show that such view can inherit important structural elements from game theoretic models of bargaining – in particular, in the case when the protagonists have overlapping negotiation regions, we emphasize a parallel to the Nash solution in cooperative game theory. When acceptable solution regions of the protagonists are disjoint, we present several types of processes: changes in the salience of dimensions, dimensional projections and metaphorical space transformations. None of the latter processes are motivated by normative or rationality considerations, but presented as argumentation tools that we believe are used in actual situations of conceptual disagreement.

: In this article we shall deal with the construction and defense of subjective identity as a topic at the intersection of psychology and anthropology. In this perspective, defense mechanisms are seen as falling along a spectrum that stretches from the individual to the collective level. The individual mind is the sphere of the intrapsychic defenses and the interpersonal maneuvers to which each of us appeals, in the relationship with other people and with one’s own environment, to defend one’s own (...) self-describability and, indissolubly, the solidity of one’s own self-conscious being. At a social and collective level, on the other hand, the individual self-protective structures are supported by cultural interventions that organize and intersubjectively “domesticate” our subjectivity and our feeling of being-there. Keywords: Autobiographical Reasoning; Defense Mechanisms; Grief; Narrative Identity; Ontological Insecurity Meccanismi di difesa: dall’individuale al collettivo Riassunto: L’articolo si occupa di costruzione e difesa dell’identità soggettiva come tema all’intersezione di psicologia e antropologia. In questa prospettiva, i meccanismi di difesa si dispongono lungo uno spettro che dal livello individuale conduce a quello collettivo. La mente individuale è la sfera delle difese intrapsichiche e delle manovre interpersonali a cui ognuno di noi fa ricorso, nella relazione con gli altri e col proprio ambiente, per difendere la propria autodescrivibilità e, inscindibilmente, la solidità del proprio essere autocosciente. Al livello sociale e collettivo, invece, le strutture autoprotettive dell’individuo sono sorrette da interventi culturali che organizzano e “addomesticano” intersoggettivamente la nostra soggettività e il nostro sentirci esistere. Parole chiave: Ragionamento autobiografico; Meccanismi di difesa; Cordoglio; Identità narrativa; Insicurezza ontologica. (shrink)

Investigating instances where lexical selection fails can lead to deeper insights into the cognitive machinery and architecture supporting successful word retrieval and speech production. In this paper, we used a multiplex lexical network approach that combines semantic and phonological similarities among words to model the structure of the mental lexicon. Network measures at different levels of analysis (degree, network distance, and closeness centrality) were used to investigate the influence of network structure on picture naming accuracy and errors by people with (...) Anomic, Broca's, Conduction, and Wernicke's aphasia. Our results reveal that word retrieval is influenced by the multiplex lexical network structure in at least two ways—(a) the accuracy of production and error type on incorrect productions were influenced by the degree and closeness centrality of the target word, and (b) error type also varied in terms of network distance between the target word and produced error word. Taken together, the analyses demonstrate that network science techniques, particularly the use of the multiplex lexical network to simultaneously represent semantic and phonological relationships among words, reveal how the structure of the mental lexicon influences language processes beyond traditionally examined psycholinguistic variables. We propose a framework for how the multiplex lexical network approach allows for understanding the influence of mental lexicon structure on word retrieval processes, with an eye toward a better understanding of the nature of clinical impairments, like aphasia.

ABSTRACTThe discursive analysis of criminal organizations’ family dynamics and ideological devices may provide important insights into the inner functioning of these groups. In this article, we describe and analyze a specific set of discursive strategies and the thematic narratives emerging from a TV interview with Giuseppe Riina, a member of Cosa Nostra and the son of one of the most important mafia bosses. Our analyses demonstrate the existence of recurring ideological devices such as reductionism, amoralism, familism, verticalism, normalism, victimism and (...) religious relativism. The results are discussed in light of previous research that examines how discursive strategies and narratives may represent powerful tools for understanding criminal organizations. Family-related discourses, in particular, reveal meanings, values and ideas that contribute to constructing criminal organizations’ internal structure, as well as their relationship with the external world.

This article focuses on ancient and contemporary accounts of selfhood and on their ontological background. Among ancient theories, the main focus are Plato’s and Plotinus’ accounts of soul and selfhood. Their ontological framework now appears outdated but, somewhat paradoxically, it also explains why Plato’s and Plotinus’ analyses are closer to a naturalised metaphysics of the self than those of the Cartesian tradition. Accordingly, human beings are not simple subjects essentially characterised by consciousness; consciousness and mental life are not co-extensive; our (...) selfhood entails a striving towards the unity of various layers. These insights come up again in recent debates, but they are now re-shaped within a framework in which philosophy of mind and behavioural sciences are combined in an effort to develop a notion of the self which is realist, yet does not entail any metaphysically grounded dualism.

The paper addresses two issues that have been recently debated in the literature on free will, moral responsibility, and the theory of punishment. The first issue concerns the descriptive project, the second both the substantive and the prescriptive project. On theoretical, historical and empirical grounds, we claim that there is no rationale for fearing that the spread of neurocognitive findings will undermine the ordinary practice of responsibility attributions. We hypothetically advocate two opposite views: that such findings would cause the collapse (...) of all punitive practices; that, on the contrary, such findings would open the way to more humane forms of punishment, which would be justified on purely utilitarian grounds. We argue that these views are both wrong, since whereas a sound punitive system can be justified without any reference to moral responsibility, it will certainly not improve the humaneness of punishment.

Sulla questione del libero filosofi, teologi e scienziati arbitrio si interrogano da più di due millenni: tuttavia essa conserva intatta tutta la sua problematicità. Già Kant sosteneva che la libertà, per quanto indispensabile sotto il profilo morale, non sia dimostrabile sul piano teorico. Nel volume il tema viene illustrato da studiosi di diversa formazione, intrecciando ricostruzione storica e analisi concettuale. I contributi mettono in luce le alternative teoriche e i nuclei tematici cruciali, emersi di volta in volta nei singoli autori (...) o periodi, con l'obiettivo di chiarire il senso complessivo di un dibattito che occupa ancora una posizione centrale sulla scena della riflessione filosofica contemporanea.

Riassunto: In una prospettiva naturalistica, lo studio della religione presenta subito un punto problematico: se essa è così diffusa, tanto da apparire un tratto inscritto nella natura umana, ciò significa che la religione comporta dei vantaggi adattivi o, quantomeno, significa che essa non comporta svantaggi tali da ostacolare la sopravvivenza di chi la pratica. Nel primo caso, si tratta di individuare la possibile funzione della religione, ovvero una qualche utilità che ne giustificherebbe il suo permanere nella storia umana. Alla luce (...) di un modello antropologico che vede l’identità soggettiva segnata da una fragilità ontologica, in questo articolo offriremo una particolare versione della tesi che assegna alla religione, quale byproduct, una funzione positiva, ipotizzando quella che potrebbe essere una sua utilità nella difesa dell’unità dell’autocoscienza. Sarà dunque sulla religione quale insieme di tecniche difensive del self che concentreremo la nostra indagine. Parole chiave : Ernesto De Martino; Naturalismo darwiniano; Meccanismi di difesa; Identità soggettiva; Religione Religion as a Defensive Technique for Subjective Identity: From a naturalistic perspective, the study of religion immediately leads to a problematic point: if religion is so widespread, to the extent that it seems to be a trait inscribed in human nature, then it should have adaptive advantages or, at the very least, it should not have disadvantages that would stand in the way of the survival of those who practice religion. In the former case, we need to understand the function of religion, viz. a utility it confers that may justify its persistence across human history. Against the backdrop of an anthropological model that considers subjectivity identity to be characterized by ontological fragility, this article will offer a special version of the claim that religion, viewed as a byproduct, has a positive function: we will make the hypothesis that it contributes to the defense of the unity of self-consciousness. Thus our focus will be on religion construed as a repertoire of strategies designed to protect the self. Keywords: Ernesto De Martino; Darwinian Naturalism; Defense Mechanisms; Subjective Identity; Religion. (shrink)

As astounding as it sounds, especially to people outside of the USA (and the Middle East, and much of Africa), 13 % of US high school teachers actively advocate creationism and so-called intelligent design theory in their classrooms; another 28 % does the right thing and teaches evolution, but a whopping 60 % falls in the middle: These teachers accept evolutionary theory (though they may be fuzzy on the details), and yet do not teach it in their classrooms, in order (...) to avoid ‘‘the controversy’’ (Berkman and Plutzer 2010). It is largely at this 60 %, and to interested undergraduate and graduate students, that Kampourakis’ new book is aimed. (shrink)

Thomas Uebel’s penetrating book represents the latest outcome of a series of investigations on Otto Neurath and the “forgotten” Vienna Circle he has published over the last ten years. Within the recent galaxy of studies devoted to logical empiricism, the re-evaluation of Neurath’s all too neglected work as well as of the “first” Vienna Circle are unquestionably very much indebted to Uebel’s contributions, which may be considered, in turn, an original development of Rudolf Haller’s pioneering studies on Austrian philosophy and (...) on its leading role in the rise of the Vienna Circle. In particular, the attention paid by Haller to Neurath’s surprising epistemological actuality and moreover the “new light” he shed on the “first” Vienna Circle 1 constitute the core of Uebel’s wide program of historical and, at the same time, philosophical research. An ambitious, but successful programm, that nowadays appears to us as essentially accomplished. (shrink)
