Besides its use in basic research, the DNA:RNA hybridization technique has helped the development of genetic engineering: it is instrumental in the isolation of specific genes that can be inserted into foreign cells, thus modifying their genetic information. Plants, animals, and microorganisms can now be altered to yield improved crops, pest-resistant plants, and a cheaper source of important proteins or drugs. The social relevance of genetic engineering received official sanction in 1980 when the U.S. Supreme Court ruled that genetically modified (...) organisms can be patented. In this article I have tried to describe the discovery of the DNA:RNA hybridization technique as the successful outcome of years of intelligent and patient research in many laboratories, of inductive and deductive processes in the minds of many biologists. The synthesis that led to the final result and to the early development of the technique was made possible by the coming together of two brilliant scientists, Sol Spiegelman and Benjamin Hall.

This article presents a review of reverse correlation in neurophysiology. We discuss the basis of reverse correlation in linear transducers and in spiking neurons. The application of reverse correlation to measure the receptive fields of visual neurons using white noise and m‐sequences, and classical findings about spatial and color processing in the cortex resulting from such measurements, are emphasized. Finally, we describe new developments in reverse correlation, including “sub‐space” and categorical reverse‐correlation. Recent results obtained by applying such methods in the (...) orientation, spatial‐frequency and Fourier domains have revealed the importance of cortical inhibition in the establishment of sharp tuning selectivity in single neurons.

We present computational modeling results based on a self‐paced reading study investigating number attraction effects in Eastern Armenian. We implement three novel computational models of agreement attraction in a Bayesian framework and compare their predictive fit to the data using k‐fold cross‐validation. We find that our data are better accounted for by an encoding‐based model of agreement attraction, compared to a retrieval‐based model. A novel methodological contribution of our study is the use of comprehension questions with open‐ended responses, so that (...) both misinterpretation of the number feature of the subject phrase and misassignment of the thematic subject role of the verb can be investigated at the same time. We find evidence for both types of misinterpretation in our study, sometimes in the same trial. However, the specific error patterns in our data are not fully consistent with any previously proposed model. (shrink)

The use of anecdotes is not a viable research strategy to study animal culture. Social learning processes can often be documented with careful quantitative analyses of observational data. Unfortunately, suggestions that killer whales engage in teaching are entirely based on subjective interpretations of qualitative observations. Thus, of teaching in killer whales cannot be used to argue for the occurrence of culture in marine mammals.

The notion of individualised evidence holds the key to solve the puzzle of statistical evidence, but there’s still no consensus on how exactly to define it. To make progress on the problem, epistemologists have proposed various accounts of individualised evidence in terms of causal or modal anti-luck conditions on knowledge like appropriate causation, sensitivity and safety. In this paper, I show that each of these fails as satisfactory anti-luck condition, and that such failure lends abductive support to the following conclusion: (...) once the familiar anti-luck intuition on knowledge is extended to individualised evidence, no single causal or modal anti-luck condition on knowledge can succeed as the right anti-luck condition on individualised evidence. This conclusion casts serious doubts on the fruitfulness of the move from anti-luck conditions on knowledge to anti-luck conditions on individualised evidence. I expand on these doubts and point out further aspects where epistemology and the law come apart: epistemic anti- luck conditions on knowledge do not adequately characterise the legal notion of individualised evidence.

Dario Martinelli’s compact and enjoyable treatise on zoömusicology, _Of Birds, Whales and Other Musicians_ introduces musicologists, biologists, social scientists, and philosophers to a new theoretical model for studying how animal behavioral patterns relate to sound communication. Organized by musical trait rather than animal species, and drawing upon the work of such esteemed philosophers as Umberto Eco, Charles Sanders Peirce, and Thomas Sebeok, Martinelli’s analyses redefine the boundaries surrounding music and help readers—scholars and amateurs alike—to appreciate the relationship between animals and (...) musicological exchanges.

In Mossio & Taraborelli (2008) we challenged the assumption according to which the ecological and sensorimotor approaches are mere conceptual variations on the same enactive theme. We showed, on the contrary, that they endorse substantially different notions of an 'action-dependent perceptual invariant' and we submitted that this distinction has interesting theoretical and empirical implications. This dissimilarity between ecological and sensorimotor theories stems, in our view, from a more fundamental divergence on the nature of perceptual information. Since Gibson's work, the ecological (...) approach has adopted a fundamentally realist stance, according to which this information is 'picked up', 'revealed', 'encountered' and 'exploited' by the organism (as a range of affordances) but not 'constituted' by the activity of the organism. In contrast, sensorimotor approaches take an explicit interactivist position, which sees the perceiver's motor activity as a determinant of perceptual information itself. Pascal & O'Regan (2008) suggest that our analysis of the relationship between ecological, sensorimotor and enactive theories would benefit from a further distinction. The original enactive approach (Varela et al. 1991; Maturana, 2002; Thompson, 2007), they argue, should not be lumped together with contemporary sensorimotor approaches to perception: whereas sensorimotor theories endorse an externalist view of perception, according to which 'perception can only be understood as a form of interaction of the organism with the environment', the original enactive approach by Varela and collaborators would have strong 'idealist underpinnings'.

The imminent deployment of autonomous vehicles requires algorithms capable of making moral decisions in relevant traffic situations. Some scholars in the ethics of autonomous vehicles hope to align such intelligent systems with human moral judgment. For this purpose, studies like the Moral Machine Experiment have collected data about human decision-making in trolley-like traffic dilemmas. This paper first argues that the trolley dilemma is an inadequate experimental paradigm for investigating traffic moral judgments because it does not include agents’ character-based considerations and (...) is incapable of facilitating the investigation of low-stakes mundane traffic scenarios. In light of the limitations of the trolley paradigm, this paper presents an alternative experimental framework that addresses these issues. The proposed solution combines the creation of mundane traffic moral scenarios using virtual reality and the Agent-Deed-Consequences (ADC) model of moral judgment as a moral-psychological framework. This paradigm shift potentially increases the ecological validity of future studies by providing more realism and incorporating character considerations into traffic actions. (shrink)

In this article, we show how postphenomenology can be used to analyze the Affinity Map: a data visualization that reveals the hidden dynamics that exist between individuals within large organizations. We make use of the Affinity Map to expand the classic postphenomenology that privileges a ‘linear’ understanding of technological mediations and introduce the notions of ‘iterativity’ and ‘collectivity.’ In the first section of the paper, we discuss both classic and more recent descriptions of human-technology-world relations in order to transcendentally approach (...) the discipline of data visualization. In the second section, we use the Affinity Map case study to consider three elements: 1) the collection of data and the design process; 2) the visual grammar of the data visualization, and 3) the process of self-recognition for the map ‘reader.’ In the third section, we introduce the hermeneutic circle of data visualization. Finally, we suggest that the Affinity Map, because of its ethical and political multistability, might be seen as a material encounter between postphenomenology, actor-network theory (ANT), and hermeneutics.

Moral intuitions are generally understood as automatic strong responses to moral facts. In this paper, I offer a metacognitive account according to which the strength of moral intuitions denotes the level of confidence of a subject. Confidence is a metacognitive appraisal of the fluency with which a subject processes information from a morally salient stimulus. I show that this account is supported by some empirical evidence, explains the main features of moral intuition and is preferable to emotional or quasi-perceptual views (...) of moral intuition.

In the summer of 1985 my children, Laura and Aurélien, then seven and five, knelt before a Barbie doll standing at the foot of a Ken doll on an imaginary cross. I remember vividly the scene because I took a picture of it. We were vacationing in Ticino and visiting the local churches, so I assumed that this play imitated the iconography to which they were being exposed. After reading Moshenska's Iconoclasm as Child's Play, however—whose cover shows “Josh McBig,” a (...) bearded version of Ken with outstretched arms and severed legs, photographed by the Jackson sisters as part of their “Doll Games” project—I have to wonder: was there not in this play an element of parody or blasphemy, of iconoclasm even, prompted perhaps by my working at the time on contemporary “vandalism”? Or, on the contrary, was there an element of devotion, of faith produced by mimicking the ritual? I am now faced with the conundrum of “the adult's imagination of the child's imagination,” to borrow a phrase (from Michael Taussig) that resonates through Moshenska's strange and fascinating book.Sometime in the 1530s, in Redcliffe Cross in Bristol, in the west of England, a preacher named Roger Edgeworth denounced what he regarded as a current upsurge of impiety and singled out as evidence that “many Images” taken from the dissolved monasteries “haue bene caryed abrod, and gyuen to children to playe wyth all,” so that when their parents ask them what it is that they are playing with, they make them laugh by answering: “I haue here myne ydoll.” “Ydoll” is a portmanteau word—as Lewis Carroll would have said—combining “doll” and “idol,” and Moshenska finds “scattered but definite evidence... that holy things were made into playthings with sufficient frequency for it to be considered an established and recognized part of iconoclastic practice in the early modern period.” He analyzes a few other examples, but Edgeworth's sermon supplies him with the primal scene of his book: he admits to “having been seduced by this passage..., caught up in its folds, brought back to it time and again,” so that Iconoclasm as Child's Play bears some structural resemblance to Henry James's novella The Turn of the Screw. Consistently—and at times obtrusively—self-reflective, it also wonders whether its approach can be regarded as “a kind of iconoclasm” or is intended “as a form of play”—lusus serius, naturally.Iconoclasm as Child's Play explores with great ingenuity the complex relationships between the Christian rite, iconoclasm, and child's play: a Byzantine empress enables her icons to survive the Quarrel of Images by calling them her “dolls”; Protestants trivialize the Roman Catholic ritual by comparing it to “trifles” and the “mere playing of children”; in The Praise of Folly, Erasmus embraces the “foolishness” of Christianity, centered on the figure of a broken body that renders attacks against its images and iconoclastic theory itself—as Bruno Latour has shown—deeply equivocal. A further turn of the screw takes place in the missionary and mercantile context of Malacca, where the Dutch settlers impute childishness both to the Portuguese Jesuits who preceded them and to the local religions. The notions of “fetish” and “fetishism,” as Moshenska shows, charge their targets with a misattribution to objects of agency, responsibility, and desires.The object of Moshenska's inquiry, which he claims less convincingly to include “art-things,” is “polysemic and polychronic,” and a leitmotif of the interpretations he proposes is the instability of the status and meaning of what is interpreted, be it a thing, an action, or a word. Among the many epistemic virtues he attributes to iconoclasm as child's play is the questioning of “the sharp... divisions between modern and premodern” implied by historical narratives such as Max Weber's account of the Reformation as the “expulsion of play” and “disenchantment” of the world. A long meditation on the temporality of play concludes by pointing out the “toy potential of all things” and referring to James Gibson's notion of “affordance.” Indeed, child's play, whatever adults want to do with it, often consists in multiplying and inventing affordances, and it is capable of turning not only “idols” into “dolls,” but also “dolls” into “idols.”.

Journal Name: Semiotica Issue: Ahead of print.

This article is a discussion of the critical remarks raised by Kristian Bankov in a notion called Bankov’s razor, about some foundational elements of the biosemiotic paradigm. The elaborated form of the “razor” includes three main questions on biosemiotic ideas, namely: 1) the philosophical grounds of the biosemiotic discourse, 2) the scientific output of biosemiotics, and 3) the ethical consequences of some biosemiotic presumptions (this latter, given its scopes and extension, is left for a future occasion). Such questions are commented (...) and challenged by Dario Martinelli, from a point of view that is primarily that of the zoosemiotician, therefore an insider of biosemiotics. In order to set the readers’ expectations in the right direction, it shall perhaps be fair to inform them that the style of the article is rather sui generis, and can hardly be classified within the genre of academic essays. Tones and terminology are more reminiscent of a philosophical pamphlet written in dialogical form. Hopefully, this choice will not compromise the scientific content of the article. (shrink)

Today, digital piracy remains a growing challenge for both legislators and businesses operating in the entertainment industry. This study explores when and why consumers make trade-offs between illegal and legal streaming services. By drawing on protection motivation theory, we find that consumers' threat and coping appraisals increase their adaptive behavior, i.e., lower intention to consume illegal and higher intention to consume legal streaming services. We also show that the strength of consumers' inherent ethical (relativism) and political (economic liberalism) identities conditions (...) adaptive behavior through social identity theory. We find that low relativism strengthens the adaptive behavior through threat appraisal, while economic liberalism strengthens the adaptive behavior through coping appraisal. Our robustness checks show that these results hold when the model accounts for the level of consumers' digital piracy attitudes. We used a scenario-based approach to test our hypotheses and surveyed 244 consumers who use streaming services. Our study contributes to the literature by showing that consumers' adaptive behavior envisioned through protection motivation theory can be weakened or strengthened by their ethical and political identities.

Financial and prosocial biases in favor of attractive adults have been documented in the labor market, in social transactions in everyday life, and in studies involving experimental economic games. According to the taste-based discrimination model developed by economists, attractiveness-related financial and prosocial biases are the result of preferences or prejudices similar to those displayed toward members of a particular sex, racial, ethnic, or religious group. Other explanations proposed by economists and social psychologists maintain that attractiveness is a marker of personality, (...) intelligence, trustworthiness, professional competence, or productivity. Evolutionary psychologists have argued that attractive adults are favored because they are preferred sexual partners. Evidence that stereotypes about attractive people are causally related to financial or prosocial biases toward them is weak or nonexistent. Consistent with evolutionary explanations, biases in favor of attractive women appear to be more consistent or stronger than those in favor of attractive men, and biases are more consistently reported in interactions between opposite-sex than same-sex individuals. Evolutionary explanations also account for increased prosocial behavior in situations in which attractive individuals are simply bystanders. Finally, evolutionary explanations are consistent with the psychological, physiological, and behavioral changes that occur when individuals are exposed to potential mates, which facilitate the expression of courtship behavior and increase the probability of occurrence of mating. Therefore, multiple lines of evidence suggest that mating motives play a more important role in driving financial and prosocial biases toward attractive adults than previously recognized. (shrink)

Ambivalence, i.e., the simultaneous holding of negative and positive evaluations toward the same object, is an empirically well-documented phenomenon and an important aspect of ordinary experience. However, it has not received sufficient philosophical attention. This essay accomplishes two aims: first, a comprehensive and empirically informed account of ambivalence is provided; second, the rationality of ambivalence in practical and nonpractical contexts is defended.

Dual-process theories of the mind emphasize how reasoning is an interplay between intuitive and reflective thinking. This paper aims to understand how the two types of processing interact in the moral domain. According to a ‘default-interventionist’ model of moral reasoning intuition and reflection are conflicting cognitions: intuitive thinking would elicit heuristic and deontological responses, whereas reflection would favour utilitarian judgements. However, the evidence for the default interventionist view is inconclusive and challenged by a growing amount of counterevidence in recent years. (...) The recent empirical findings favour an interdependent rather than conflicting view of the two types of information processing in the moral domain. In this view, which I call dual-process reflective equilibrium, intuition and reflection cooperate in moral reasoning to reach a reflective goal, which is supposedly normative justification. In sum, on the one hand, the scope of moral intuitions extends to selecting relevant information and calling for reflection whenever a problem presents conflicting aspects; on the other hand, the purpose of moral reflection is to rationalize pre-reflective intuitions to provide articulated and accessible reasons.

The purpose of this study was to examine the perceptions of American history among adolescent Mexican Americans at the eight-grade level in a mid-west town's middle school. This qualitative study shows that multiple contexts influenced the process of teaching and learning history between and among a white teacher and adolescent Mexican Americans at Atkinson Middle School. Those overlapping contexts (the context of the education of minority language students, the context of social studies education, and the school's culture) created a unique (...) totality responsible for shaping the experiences of learning American history by Mexican-American students. These experiences were detrimental for the appreciation by Mexican-American students of American history's potential meanings and significance. (shrink)

Kierkegaard's notion of the aesthetic covers at least two interrelated aspects. On the one hand, it defines a way of existence characterized by either the immediate embodiment or the reflective contemplation of life's possibilities. On the other hand, it indicates the investigation of those possibilities of life within the medium of certain works of art and narratives. Both aspects entail a critical approach to existence on the basis of ethical and religious presuppositions.

This report is an attempt to reread the event of Revelation in view of DV 8: «Ecclesia, volventibus saeculis, ad plenitudinem divinae veritatis iugiter tendit, donec in ipsa consummentur verba Dei». The text aims at clarifying the eschatological character of Revelation, raising however a theological problem of great importance: if and in what measure is it possible to think of Revelation as a never concluded process, if the theological tradition asserts that Revelation is concluded with the death of the last (...) Apostle and Dei Verbum speaks of Christ as the fullness of Revelation? The eschatological character of Revelation is investigated in the light of the dynamism of the Tradition, in particular of DV 8, which gives indications of great interest to resolve the matter of the persistence of Revelation in the time of the Church. The report affirms that the Tradition does not limit itself to the understanding of the revealed fact, but it points out the participation of the Church in the dynamism of Revelation itself. The conclusion is reached by means of a description of the constitutive relationship between Christian experience and knowledge - described in Dei Verbum as intima spiritualium rerum quam experiuntur intelligentia - which has it most clear and most pertinent expression in the sensus fidei.

Previous accounts of cognitive skill acquisition have demonstrated how procedural knowledge can be obtained and transformed over time into skilled task performance. This article focuses on a complementary aspect of skill acquisition, namely the integration and reuse of previously known component skills. The article posits that, in addition to mechanisms that proceduralize knowledge into more efficient forms, skill acquisition requires tight integration of newly acquired knowledge and previously learned knowledge. Skill acquisition also benefits from reuse of existing knowledge across disparate (...) task domains, relying on indexicals to reference and share necessary information across knowledge components. To demonstrate these ideas, the article proposes a computational model of skill acquisition from instructions focused on integration and reuse, and applies this model to account for behavior across seven task domains.

As artificial intelligence (AI) continues to advance, one key challenge is ensuring that AI aligns with certain values. However, in the current diverse and democratic society, reaching a normative consensus is complex. This paper delves into the methodological aspect of how AI ethicists can effectively determine which values AI should uphold. After reviewing the most influential methodologies, we detail an intuitionist research agenda that offers guidelines for aligning AI applications with a limited set of reliable moral intuitions, each underlying a (...) refined cooperative view of AI. We discuss appropriate epistemic tools for collecting, filtering, and justifying moral intuitions with the aim of reducing cognitive and social biases. The proposed methodology facilitates a large collective participation in AI alignment, while ensuring the reliability of the considered moral judgments. (shrink)

This article describes the path‐mapping theory of how humans integrate analogical mapping and general problem solving. The theory posits that humans represent analogs with declarative roles, map analogs by lower‐level retrieval of analogous role paths, and coordinate mappings with higher‐level organizational knowledge. Implemented in the ACT‐R cognitive architecture, the path‐mapping theory enables models of analogical mapping behavior to incorporate and interface with other problem‐solving knowledge. Path‐mapping models thus can include task‐specific skills such as encoding analogs or generating responses, and can (...) make behavioral predictions at the level of real‐world metrics such as latency or correctness. We show that the path‐mapping theory can successfully account for the major phenomena addressed by previous theories of analogy. We also describe a path‐mapping model that can account for subjects' incremental eye‐movement and typing behavior in a story‐mapping task. We discuss extensions and implications of this work to other areas of analogy and problem‐solving research. (shrink)

​This contributed volume gives access to semiotic researches adopting a quantitative stance. European semiotics is traditionally based on immanent methodologies: meaning is seen as an autonomous dimension of human existence, whose laws can be investigated via purely qualitative analytical and reflexive analysis. Today, researches crossing disciplinary boundaries reveal the limitations of such an homogeneous practice. In particular, two families of quantitative research strategies can be identified. On the one hand, researchers wish to naturalize meaning, by making semiotic results interact with (...) those coming from Neurophysiological and psychological sciences. On the other hand, statistical and computational tools are adopted to work on linguistic and multimedia corpora. The book acts to put the two approaches into dialogue. (shrink)

Moral particularism, in its extreme version, is the theory that argues that there are no invariant context-independent moral reasons. It states also that moral knowledge is not constituted by principles and that these are useless or harmful in practice. In this paper, I intend to argue that this position takes context-sensitiveness of reasons too seriously and has to face many philosophical problems—mainly because its most important argument (the argument from holism of reasons) is not convincing but also because a pluralist (...) generalist account is preferable both from metaethical and normative points of view.

The article aims at showing how far the technologies of audiovisual registration affect not only the ontology of images but also our sense of realism in politics and history. As argue Jacques Derrida and Bernard Stiegler, historical events have become “tele-events” after the birth of these technologies. Our handling with images has changed accordingly. As argues Pietro Montani, we no longer consider them as “copies” of real objects but rather as “occasions” for initiating processes of “validation” of history. Hannah Arendt’s (...) opposition between the ancient concept of history being based on praxis and the modern concept of history as “fabrication” (poiesis) of the humankind must be therefore reconsidered. History is rather the negotiation between these two attitudes (praxis and poiesis): cinema might be one of the exemplary sources of this negotiation, as epitomized by the documentary work in the audiovisual archives conducted by Esfir Shub (1927) and Harun Farocki (1992). Representation (Louis Martin) becomes thus a dynamical power of imagination dealing with historical and political reality; consequently, the “ideal spectator”, just as the “ideal reader” for novels (Umberto Eco), is charged with a new task of actualizing the sense of images with regard to their historical and political references.

We explore a notion of pseudofinite dimension, introduced by Hrushovski and Wagner, on an infinite ultraproduct of finite structures. Certain conditions on pseudofinite dimension are identified that guarantee simplicity or supersimplicity of the underlying theory, and that a drop in pseudofinite dimension is equivalent to forking. Under a suitable assumption, a measure-theoretic condition is shown to be equivalent to local stability. Many examples are explored, including vector spaces over finite fields viewed as 2-sorted finite structures, and homocyclic groups. Connections are (...) made to products of sets in finite groups, in particular to word maps, and a generalization of Tao's Algebraic Regularity Lemma is noted. (shrink)

Beccaria’s penal philosophy hinges on the doctrinal paradigm of liberty through law. Inconceivable in the absence of laws and unattainable in the presence of arbitrary powers, liberty is profiled as the legal situation of the person who may act, within the sphere of what is not forbidden and not bound, without suffering illicit interference from private individuals or organs of the state. Thus, the form of law becomes an essential matter in the construction of the political space suitable for free (...) living. In the analysis proposed in this article, the notion of “political liberty”–which Beccaria takes from Montesquieu–is declined in relation to the legal order, criminal law and the social contract.
