We identify a social phenomenon in which large numbers of people seem to work towards a shared goal without explicitly trying to do so. We argue that this phenomenon – implicit coordination – is best understood as a form of joint agency differing from the forms most commonly discussed in the literature in the same way that individual actions driven by “explicit” intentions (those available for reflection and report) differ from individual actions driven by “implicit” intentions (those not (...) thus available). More precisely, implicit coordination is both analogous to wholly implicit individual intentions, and constituted by the partly implicit intentions of participants. We discuss the significance of this category for action theory, social ontology, and social criticism. (shrink)

This book attempts to marry truth-conditional semantics with cognitive linguistics in the church of computational neuroscience. To this end, it examines the truth-conditional meanings of coordinators, quantifiers, and collective predicates as neurophysiological phenomena that are amenable to a neurocomputational analysis. Drawing inspiration from work on visual processing, and especially the simple/complex cell distinction in early vision (V1), we claim that a similar two-layer architecture is sufficient to learn the truth-conditional meanings of the logical coordinators and logical quantifiers. As a prerequisite, (...) much discussion is given over to what a neurologically plausible representation of the meanings of these items would look like. We eventually settle on a representation in terms of correlation, so that, for instance, the semantic input to the universal operators (e.g. and, all)is represented as maximally correlated, while the semantic input to the universal negative operators (e.g. nor, no)is represented as maximally anticorrelated. On the basis this representation, the hypothesis can be offered that the function of the logical operators is to extract an invariant feature from natural situations, that of degree of correlation between parts of the situation. This result sets up an elegant formal analogy to recent models of visual processing, which argue that the function of early vision is to reduce the redundancy inherent in natural images. Computational simulations are designed in which the logical operators are learned by associating their phonological form with some degree of correlation in the inputs, so that the overall function of the system is as a simple kind of pattern recognition. Several learning rules are assayed, especially those of the Hebbian sort, which are the ones with the most neurological support. Learning vector quantization (LVQ) is shown to be a perspicuous and efficient means of learning the patterns that are of interest. We draw a formal parallelism between the initial, competitive layer of LVQ and the simple cell layer in V1, and between the final, linear layer of LVQ and the complex cell layer in V1, in that the initial layers are both selective, while the final layers both generalize. It is also shown how the representations argued for can be used to draw the traditionally-recognized inferences arising from coordination and quantification, and why the inference of subalternacy breaks down for collective predicates. Finally, the analogies between early vision and the logical operators allow us to advance the claim of cognitive linguistics that language is not processed by proprietary algorithms, but rather by algorithms that are general to the entire brain. Thus in the debate between objectivist and experiential metaphysics, this book falls squarely into the camp of the latter. Yet it does so by means of a rigorous formal, mathematical, and neurological exposition – in contradiction of the experiential claim that formal analysis has no place in the understanding of cognition. To make our own counter-claim as explicit as possible, we present a sketch of the LVQ structure in terms of mereotopology, in which the initial layer of the network performs topological operations, while the final layer performs mereological operations. The book is meant to be self-contained, in the sense that it does not assume any prior knowledge of any of the many areas that are touched upon. It therefore contains mini-summaries of biological visual processing, especially the retinocortical and ventral /what?/ parvocellular pathways computational models of neural signaling, and in particular the reduction of the Hodgkin-Huxley equations to the connectionist and integrate-and-fire neurons Hebbian learning rules and the elaboration of learning vector quantization the linguistic pathway in the left hemisphere memory and the hippocampus truth-conditional vs. image-schematic semantics objectivist vs. experiential metaphysics and mereotopology. All of the simulations are implemented in MATLAB, and the code is available from the book’s website. • The discovery of several algorithmic similarities between visison and semantics. • The support of all of this by means of simulations, and the packaging of all of this in a coherent theoretical framework.

To advance understanding of the mechanisms allowing for team coordination (TC) in complex motor actions, we conducted a qualitative study with eight elite hand-to-hand circus acrobats. Data collection consisted of field observations, an open-ended interview with the participants’ head coach, and focus group interviews with all acrobats. Data analysis yielded three higher order themes: TC, collective efficacy (CE), and TC-CE linkage. Teammates’ shared and complementary mental models, as well as implicit and explicit communication dynamics, emerged as formative sub-themes (...) of TC; self-efficacy and other’s-efficacy emerged as reflective sub-themes of CE. Our findings also suggest that TC is likely inter-related to CE in a systemic fashion. Practitioners should encourage the development of both shared and complementary models of thinking, while promoting verbal and non-verbal communication skills. Finally, increasing teammates’ confidence in themselves and in their teammates can help in the development of CE as well as the enhancement of TC. (shrink)

In the light of our recently performed experiments, revealing the anisotropy of light velocity in any frame moving with respect to absolute space, we show that the Lorentz transformation, where the relativity of light velocity is given implicitly through the relativity of the time coordinates, must be treated from an absolute point of view if one seeks to preserve its adequacy to physical reality. Then we propose a new transformation (which is to be considered as a legitimate companion of the (...) Lorentz transformation) wherein the relativity of light velocity is given explicitly and the time coordinates are absolute. (shrink)

What does it take to argue well? The goal of this series of studies was to better understand the cognitive skills entailed in argument, and their course of development, isolated from the verbal and social demands that argumentive discourse also entails. Findings indicated that young adolescents are less able than adults to coordinate attention to both positions in an argument, an age-related pattern that parallels one found in discourse. Contributing to this weakness was inattention to the opposing position (in both (...) constrained and unconstrained formats), but not ability to address the opposing position when explicitly asked to do so. In addition to implementing the necessary dual focus, results point to the importance of developing epistemological understanding of the relevance of the opposing position to argument, as well as of the goals of argument more generally. The results also reflect the close parallels between dialogic and non-dialogic argument. (shrink)

Categorial grammar is well-known for its elegant analysis of coordination enabled by the flexible notion of constituency it entertains. However, to date, no systematic study exists that examines whether this analysis has any obvious empirical advantage over alternative analyses of nonconstituent coordination available in phrase structure-based theories of syntax. This paper attempts precisely such a comparison. We compare the direct constituent coordination analysis of non-canonical coordinations in categorial grammar with an ellipsis-based analysis of the same phenomena in (...) the recent HPSG literature. We provide a set of empirical evidence, consisting of cases in which non-canonical coordinations interact with scopal operators of various sorts, which systematically falsifies the predictions of the latter, ‘linearization-based’ ellipsis approach to coordination. We propose an alternative analysis in a variant of categorial grammar called Hybrid Type-Logical Categorial Grammar. The proposed framework builds on both the Lambek-inspired variants of categorial grammar and a more recent line of work modelling word order via a lambda calculus for the prosodic component. The flexible syntax–semantics interface of this framework straightforwardly captures the interactions between non-canonical coordinations and scopal expressions, demonstrating the broader empirical payoff of the direct constituent coordination analysis of non-canonical coordinations pioneered by Steedman :523–568, 1985; Linguist Philos 13:207–263, 1990) and Dowty hitherto not explicitly recognized in the literature.

In this paper I present the double disjunction task as introduced by Johnson-Laird. This experiment is meant to show how mental model theory explains the discrepancy between logical competence and logical performance of individuals in deductive reasoning. I review the results of the task and identify three problems in the way the task is designed, that all fall under a lack of coordination between the subject and the experimenter, and an insufficient representation of the semantic/pragmatic interface. I then propose (...) a reformulation of the task, that makes explicit the underlying semantic reasoning and emphasizes the difference of interpretation of the DDT between the experimenter and the subjects.

We have developed an approach to implementing a system for managing situated knowledge for complex instruments. Our aim is to develop a system that guides a user through the steps for operating complex scientific instruments. A user manual is often inadequate support for a community of users, so direct communication with an expert is often required. One reason for this is that not all of the author’s expert knowledge was included in the manual, thus limiting the contents to explicit (...) knowledge. This is a main concern of modern knowledge management practitioners who are attempting to design systems that consider both explicit and tacit knowledge. The key is to distribute explicit knowledge through interaction with the real world so that users can develop tacit knowledge as well as acquire explicit knowledge. We describe technical difficulties related to referencing the real world, which is required for interaction, and describe a novel approach to building a low-cost three-dimensional pointer for obtaining the required knowledge, which constitutes our preliminary result.

In social and cultural theory, topology has been used to articulate changes in structures and spaces of power. In this introduction, we argue that culture itself is becoming topological. In particular, this ‘becoming topological’ can be identified in the significance of a new order of spatio-temporal continuity for forms of economic, political and cultural life today. This ordering emerges, sometimes without explicit coordination, in practices of sorting, naming, numbering, comparing, listing, and calculating. We show that the effect of (...) these practices is both to introduce new continuities into a discontinuous world by establishing equivalences or similitudes, and to make and mark discontinuities through repeated contrasts. In this multiplication of relations, topological change is established as being constant, normal and immanent, rather than being an exceptional form, which is externally produced; that is, forms of economic, political and cultural life are identified and made legible in terms of their capacities for continuous change. Outlining the contributions to this Special Issue, the introduction discusses the meaning of topological culture and provides an analytic framework through which to understand its implications.

An explicit feature of the World Health Organisation’s response to the COVID-19 pandemic has been to ensure that naming conventions, both for the disease itself and for the variants of its underlying virus, should not have a stigmatising effect on any one population or region. An implicit feature of this undertaking is the recognition that the relation between ‘what is said’ and ‘what is heard’ involves an ongoing and even generative tension that cannot be mapped following a defined set (...) of coordinates. The reason for this, the following paper claims, employing the work of Barbara Cassin, is that there is a uniquely performative (epideictic) aspect to language – one that takes place in a uniquely non-globalised space whose extension remains unscripted or extemporised, a space that is often distended and sometimes localisable but ultimately indivisible. Such a space, this paper shows, is one oriented by an understanding of rhetoric whereby utterances obtain according to the actual use [chreia] or decisive moment [kairos] – as opposed to any definitive place [topos] – of what is said.

When two people move in synchrony, they become more social. Yet it is not clear how this effect scales up to larger numbers of people. Does a group need to move in unison to affiliate, in what we term unitary synchrony; or does affiliation arise from distributed coordination, patterns of coupled movements between individual members of a group? We developed choreographic tasks that manipulated movement synchrony without explicitly instructing groups to move in unison. Wrist accelerometers measured group movement dynamics (...) and we applied cross-recurrence analysis to distinguish the temporal features of emergent unitary synchrony and distributed coordination. Participants’ unitary synchrony did not predict pro-social behavior, but their distributed coordination predicted how much they liked each other, how they felt toward their group, and how much they conformed to each other's opinions. The choreography of affiliation arises from distributed coordination of group movement dynamics. (shrink)

A coordinate-free formulation is established for (semi) classical particle-field interactions. The exterior language of spacetime chains and De-Rham currents enables the description to include extended strings and membranes besides point particles. Treating physical fields in terms of sections of particular bundles, a unified account of interactions is presented in terms of an intrinsic action principle on a bundle of jets over spacetime. The theory is illustrated by considering the specific model of point particles with intrinsic spin covariantly coupled to theU(1) (...) andSL(2, C) connections describing the electromagnetic and gravitational fields, respectively. The notion of dual spin is examined in this context and coupled equations for this particle-field system are explicitly derived in a local chart. Attention is drawn to the global implications of the theory. (shrink)

A basic issue in political economy is the question of how a decentralized economy is possible: How can a system survive and, moreover, be efficient, if all decisions are taken independently, that is, without any explicit coordination? The issue has two sides to it. On the one hand, it is a “thought experiment,” falsifiable only on logical grounds, an object of debate for the sake of pure intellectual interest, even for people who might not live in a market (...) economy. On the other hand, for those who do or might live in such an economy, a thought experiment of this kind contains a critical political dimension, for the conclusions derived from it will usually be appealed to in arguing about the ideal organization of the economy.

Descriptors: coordination, autonomy, actions, beliefs Abstract Distributing authority among autonomous agents can induce inconsistency costs if the agents act as if they disagree. If we define an agent’s “marginal beliefs” to be the odds at which it is willing to make bets, we find that a betting market can induce agents to act as if they almost agree, not only with respect to the bets they offer but also other actions they take. In a particular “Mars mining” scenario, I (...) explicitly show how utility maximizing agents, who are autonomous and hence distrust each other, can discover a common consensus and take concrete physical actions as if they agreed with that consensus, lowering costs to the group as a whole. Though limited, the approach has also has many unexplored possibilities. A previous version of this paper was presented at the IJCAI-91 Workshop on Reasoning in Adversarial Domains (This version is missing some cites and the graphics.). (shrink)

Since it was first proposed by Moses, Shoham, and Tennenholtz, the social laws paradigm has proved to be one of the most compelling approaches to the offline coordination of multiagent systems. In this paper, we make four key contributions to the theory and practice of social laws in multiagent systems. First, we show that the Alternating-time Temporal Logic (atl) of Alur, Henzinger, and Kupferman provides an elegant and powerful framework within which to express and understand social laws for multiagent (...) systems. Second, we show that the effectiveness, feasibility, and synthesis problems for social laws may naturally be framed as atl model checking problems, and that as a consequence, existing atl model checkers may be applied to these problems. Third, we show that the complexity of the feasibility problem in our framework is no more complex in the general case than that of the corresponding problem in the Shoham–Tennenholtz framework (it is np-complete). Finally, we show how our basic framework can easily be extended to permit social laws in which constraints on the legality or otherwise of some action may be explicitly required. We illustrate the concepts and techniques developed by means of a running example. (shrink)

There seems to exist a general consensus on how to conceptualize cooperation in the field of international relations (IR). We argue that this impression is deceptive. In practice, scholars working on the causes of international cooperation have come to implicitly employ various understandings of what cooperation is. Yet, an explicit debate about the discipline's conceptual foundations never materialized, and whatever discussion occurred did so only latently and without much dialog across theoretical traditions. In this paper, we develop an updated (...) conceptual framework by exploring the nature of these differing understandings and situating them within broader theoretical conversations about the role of cooperation in IR. Drawing on an array of studies in IR and philosophy, our framework distinguishes between three distinct types of cooperative state interactions – cooperation through tacit policy coordination (‘minimal’ cooperation), cooperation through explicit policy coordination (‘thin’ cooperation), and cooperation based on joint action (‘thick’ cooperation). The framework contributes to better theorization about cooperation in two main ways: it allows scholars across theoretical traditions to identify important sources of disagreement and previously unnoticed theoretical common ground; and the conceptual disaggregation it provides grants scholars crucial theoretical leverage by enabling type-specific causal theorization.

Unlike most other sciences, psychology has no true core theory to guide a coherent research programme. It does have James J Gibson’s ecological approach to visual perception, however, which we suggest should serve as an example of the benefits a good theory brings to psychological research. Here we focus on an example of how the ecological approach has served as a guide to discovery, shaping and constraining a recent hypothesis about how humans perform coordinated rhythmic movements (Bingham 2004a, b). Early (...) experiments on this task were framed in a dynamic pattern approach. This phenomenological, behavioural framework (e.g. Jeka & Kelso 1989) classifies the behaviour of complex action systems in terms of the key order parameters, and describes the dynamical stability of the system as it responds to perturbations. Dynamical systems, however, while a valuable toolkit, is not a theory of behaviour, and this style of research is unable to successfully predict data it is not explicitly designed to fit. More recent work by Bingham & colleagues has used dynamical systems to formalise hypotheses derived from Gibson’s ecological approach to perception and action, with a particular emphasis on perceptual information. The resulting model (Bingham 2001, 2004a, b; Snapp-Childs et al. 2011) has had great success with both the phenomena it was designed to explain as well as a wide range of empirical results from a version of the task it is not specifically designed to explain (specifically, learning a novel coordination). This model and the research programme that produced it stand as an example of the value of theory driven research, and we use it to illustrate the contemporary importance the ecological approach has for psychology.

I will first discuss how social interactions organize, coordinate, and specialize as “artifacts,” tools; how these tools are not only for coordination but for achieving something, for some outcome (goal/function), for a collective work. In particular, I will argue that these artifacts specify (predict and prescribe) the mental contents of the participants, both in terms of beliefs and acceptances and in terms of motives and plans. We have to revise the behavioristic view of “scripts” and “roles”; when we play (...) a role we wear a “mind.” No collective action would be possible without shared and/or ascribed mental contents. This is also very crucial for a central form of automatic mind-reading (mind ascription). Second, I will argue that often what really matters is the ascribed/prescribed, worn, mind not the real, private one. We have to play (like in the symbolic play) “as if” we had those mental contents. This social convention and mutual assumption makes the interaction work. The ascribed beliefs and goals are not necessarily explicitly there; they might be just implicit as inactive (we act just by routine and automatically) or implicit as potential. The coordination and social action works thanks to these “as if” (ascribed and pretended) minds, thanks to those conventional constructs. Our social minds for social interactions are coordination artifacts and social institutions. (shrink)

This essay aims at providing a brief analysis of John Dewey’s 1896 essay The reflex arc concept in psychology by identifying in it “proto-aesthetic” elements that will be thematized in an explicitly aesthetic sense only, almost forty years later, in Art as experience. This latter can be indeed considered both as a hapax and an apex of a path in which Dewey progressively focuses on matters that can be deemed properly aesthetic and of which The reflex arc concept in psychology (...) can be seen as one of the first steps. Our analysis will attempt at showing this connection by spanning the reflex arc idea, amended by Dewey in this essay, and that of “an” experience as a proper aesthetic experience through the fundamental concept of coordination.

The standard coordinate-based formulation of the space-time theory of special relativity (Minkowski geometry) is philosophically unsatisfactory for various reasons. We here present an explicit axiomatic formulation of that theory in terms of primitives with a definitive physical interpretation, prove its equivalence to the standard coordinate formulation, and draw various philosophical conclusions concerning the physical content and assumptions of the space-time theory. The prevalent causal interpretation of physical Minkowski geometry deriving from Reichenbach is criticised on the basis of the present (...) formulation. (shrink)

This chapter provides some tentative conclusions about the likely linguistic status of context‐sensitive semantic properties. It argues that pragmatism is fully aligned with a standard approach to syntax, and should be the default view of the notion of a linguistic 'context', viz., context is not a well‐behaved linguistic notion. But rather a potentially open‐ended way of marking the role extra‐linguistic factors can play in fixing what is said on an occasion of the use of a linguistic type. Context sensitivity is (...) not restricted to the construal of overt linguistic material. It also appears that the construal of tokens of many constructions depends upon contextual factors that are not explicitly encoded in linguistic material; that is, if pronouns are explicit variables, then there appear to be implicit or covert variables as well. Truth‐value of a sentence in context is assigned relative to the value a coordinate of the index takes under the scope of the operator. (shrink)

People are not as fast or as strong as many other creatures that evolved around us. What gives us an evolutionary advantage is working together to achieve common aims. Coordinating joint action begins at a tender age with such cooperative activities as alternating babbling and clapping games. Adult joint activities are far more complex and use multiple means of coordination. Joint action has attracted qualitative analyses by sociolinguists, cognitive scientists, and philosophers as well as empirical analyses and theories by (...) cognitive scientists. Here, we analyze how joint action is spontaneously coordinated from start to finish in a novel complex real‐life joint activity, assembling a piece of furniture, a task that captures the essentials of joint action, collaborators, things in the world, and communicative devices. Pairs of strangers assembled a TV cart from a stack of parts and a photo of the completed cart. Coordination prior to each assembly action was coded as explicit, using speech or gesture, or implicit, actions that both advanced the task and communicated the next step. Initial planning relied on explicit communication about structure, but not action nor division of labor, which were improvised. That served to establish a joint representation of the goal that informed actions and monitored progress. As assembly progressed, coordination was increasingly implicit, through actions alone. Joint action is a dynamic interplay of explicit and implicit signaling with respect to things in the world to coordinate ongoing progress, guided by a shared representation of the goal. (shrink)

Craniology – the practice of inferring intelligence differences from the measurement of human skulls – survived the dismissal of phrenology and remained a widely popular research program until the end of the nineteenth century. From the 1970s, historians and sociologists of science extensively focused on the explicit and implicit socio-cultural biases invalidating the evidence and claims that craniology produced. Building on this literature, I reassess the history of craniological practice from a different but complementary perspective that relies on recent (...) developments in the epistemology of measurement. More precisely, I identify two aspects of the measurement culture of nineteenth-century craniologists that are crucial to understand the lack of validity of craniological inference: their neglect of the problem of coordination for their presupposed quantification of intelligence and their narrow view of calibration. Based on my analysis, I claim that these methodological shortcomings amplified the impact of the socio-cultural biases of craniologists, which had a pervasive role in their evidential use of measurement. Finally, my argument shows how the epistemology of measurement perspective can offer useful tools in debates concerning the use of biological evidence to foster social discourse and for analyzing the relationship between theory, evidence, and measurement.

The human mind is extraordinary in its ability not merely to respond to events as they unfold but also to adapt its own operation in pursuit of its agenda. This ‘cognitive control’ can be achieved through simple interactions among sensorimotor processes, and through interactions in which one sensorimotor process represents a property of another in an implicit, unconscious way. So why does the human mind also represent properties of cognitive processes in an explicit way, enabling us to think and (...) say ‘I’m sure’ or ‘I’m doubtful’? We suggest that ‘system 2 metacognition’ is for supra-personal cognitive control. It allows metacognitive information to be broadcast, and thereby to coordinate the sensorimotor systems of two or more agents involved in a shared task. (shrink)

As an explicit organizing metaphor, memory aid, and conceptual framework, the prefrontal cortex may be viewed as a five-member ‘Executive Committee,’ as the prefrontal-control extensions of five sub-and-posterior-cortical systems: the ‘Perceiver’ is the frontal extension of the ventral perceptual stream which represents the world and self in object coordinates; the ‘Verbalizer’ is the frontal extension of the language stream which represents the world and self in language coordinates; the ‘Motivator’ is the frontal cortical extension of a subcortical extended-amygdala stream (...) which represents the world and self in motivational/emotional coordinates; the ‘Attender’ is the frontal cortical extension of a subcortical extended-hippocampal stream which represents the world and self in spatiotemporal coordinates and directs attention to internal and external events; and the ‘Coordinator’ is the frontal extension of the dorsal perceptual stream which represents the world and self in body- and eye-coordinates and controls willed action and working memory. This tutorial review examines the interacting roles of these five systems in perception, working memory, attention, long - term memory, motor control, and thinking. (shrink)

Online controlled experiments, also known as A/B tests, have become ubiquitous. While many practical challenges in running experiments at scale have been thoroughly discussed, the ethical dimension of A/B testing has been neglected.

More precisely, the article (a) introduces a (...) set of principles to encourage ethical and responsible experimentation to protect users, customers, and society; (b) argues that ensuring compliance with the proposed principles is a complex challenge unlikely to be addressed by resorting to a one-solution response; (c) discusses the relevance and effectiveness of several mechanisms and policies in educating, governing, and incentivizing companies conducting online controlled experiments; and (d) offers a list of prompting questions specifically designed to help and empower practitioners by stimulating specific ethical deliberations and facilitating coordination among different groups of stakeholders.

ven a cursory look at the extensive literature on mindreading in nonhuman animals reveals considerable variation both in what mindreading abilities are taken to be, and in what is taken as evidence for them. Claims that seem to contradict each other are often not inconsistent with each other when examined more closely. And sometimes theorists who seem to be on the same side are actually talking at cross-purposes. The first aim of this paper is to tackle some important framework questions (...) about how exactly the mindreading hypothesis is to be stated. It emerges in sections 1 and 2 that there are three importantly different versions of the mindreading hypothesis that need to be distinguished. The first (which I call minimal mindreading) occurs when a creature’s behavior covaries with the psychological states of other participants in social exchanges. The presence of minimal mindreading is not in itself evidence for the presence of what I term substantive mindreading. Substantive mindreading involves attributions of mental states. There are different levels of substantive mindreading, varying according to the category of mental state attributions that they involve. Section 2 explores different types of substantive mindreading, according to the extent to which they involve explicitly representing the agent’s backgtround psychological profile. This gives us a principled way of distinguishing propositional attitude mindreading from perceptual mindreading. -/- It is clear that much of the reasoning behind attributions of mindreading abilities to nonlinguistic creatures is analogical in nature. We see in section 3 that much of the discussion in this area proceeds on the basis of a double analogy between animal cognition and human cognition. Researchers assume both that animals solve many problems of social coordination that are analogous to problem solved by humans and that since humans solve those problems using mindreading strategies, so too do non-human animals. How we apply the second analogy, of course, depends upon our interpretation of the particular mindreading strategies that humans employ – in particular, it depends upon the centrality of propositional attitude psychology (or folk psychology) in human social understanding and social coordination. There are good reasons for thinking that the role of propositional attitude psychology in human social life is very much over-stated. This has repercussions for how we think about substantive mindreading in nonhuman animals. It very much weakens the analogical case for identifying propositional attitude mindreading in nonlinguistic creatures. -/- Suspicion of claims of propositional attitude mindreading in non-human animals turns out to be well-founded. In section 4 I present a revised version of an argument I have given elsewhere (Bermúdez 2003) to show that the most sophisticated form of substantive mindreading (the type of mindreading that exploits the concepts of propositional attitude psychology) is only available to language-using creatures.

In this paper, the meanings of sentences containing the word or and a modal verb are used to arrive at a novel account of the meaning of or coordinations. It is proposed that or coordinations denote sets whose members are the denotations of the disjuncts; and that the truth conditions of sentences containing or coordinations require the existence of some set made available by the semantic environment which can be ‘divided up’ in accordance with the disjuncts. The relevant notion of (...) ‘dividing things up’ is made explicit in the paper. Detailed attention is given to the question of how the proposed truth conditions are derived from the syntactic input. The account offered allows for the derivation of both the disjunctive and the nondisjunctive readings of modal/or sentences, including the much-discussed free choice readings of may/or sentences.

The use of Intelligent Assistive Technology in dementia care opens the prospects of reducing the global burden of dementia and enabling novel opportunities to improve the lives of dementia patients. However, with current adoption rates being reportedly low, the potential of IATs might remain under-expressed as long as the reasons for suboptimal adoption remain unaddressed. Among these, ethical and social considerations are critical. This article reviews the spectrum of IATs for dementia and investigates the prevalence of ethical considerations in the (...) design of current IATs. Our screening shows that a significant portion of current IATs is designed in the absence of explicit ethical considerations. These results suggest that the lack of ethical consideration might be a codeterminant of current structural limitations in the translation of IATs from designing labs to bedside. Based on these data, we call for a coordinated effort to proactively incorporate ethical considerations early in the design and development of new products. (shrink)

The emergence of human communication systems is typically investigated via 2 approaches with complementary strengths and weaknesses: naturalistic studies and computer simulations. This study was conducted with a method that combines these approaches. Pairs of participants played video games requiring communication. Members of a pair were physically separated but exchanged graphic signals through a medium that prevented the use of standard symbols (e.g., letters). Communication systems emerged and developed rapidly during the games, integrating the use of explicit signs with (...) information implicitly available to players and silent behavior‐coordinating procedures. The systems that emerged suggest 3 conclusions: (a) signs originate from different mappings; (b) sign systems develop parsimoniously; (c) sign forms are perceptually distinct, easy to produce, and tolerant to variations.

Recent accounts of mindreading—i.e., the human capacity to attribute mental states to interpret, explain, and predict behavior—have suggested that it has evolved through cultural rather than biological evolution. Although these accounts describe the role of culture in the ontogenetic development of mindreading, they neglect the question of the cultural origins of mindreading in human prehistory. We discuss four possible models of this, distinguished by the role they posit for culture: the standard evolutionary psychology model, the individualist empiricist model, the cultural (...) empiricist model, and the radical socio-cultural constructivist model, which we favor. We motivate model by arguing that many forms of mental state ascription do not serve the function of simply describing inner states causally responsible for the behavior of a cognitive agent; rather, they relate the agent to her environment by characterizing her practical commitments. Making these practical commitments explicit has an important regulatory function in that it supports action coordination and alignment on joint goals. We propose a model of how the ascription of mental states may have evolved as a linguistic device to perform exactly this function of making agents’ practical commitments explicit. (shrink)

For the past two decades, Einstein's Hole Argument (which deals with the apparent indeterminateness of general relativity due to the general covariance of the field equations) and its resolution in terms of "Leibniz equivalence" (the statement that pseudo-Riemannian geometries related by active diffeomorphisms represent the same physical solution) have been the starting point for a lively philosophical debate on the objectivity of the point-events of space-time. It seems that Leibniz equivalence makes it impossible to consider the points of the space-time (...) manifold as physically individuated without recourse to dynamical individuating fields. Various authors have posited that the metric field itself can be used in this way , but nobody so far has considered the problem of explicitly distilling the "metrical fingerprint" of point-events from the gauge-dependent elements of the metric field. Working in the Hamiltonian formulation of general relativity, and building on the results of Lusanna and Pauri (2002), we show how Bergmann and Komar's "intrinsic pseudo-coordinates" (based on the value of curvature invariants) can be used to provide a physical individuation of point-events in terms of the true degrees of freedom (the "Dirac observables") of the gravitational field, and we suggest how this conceptual individuation could in principle be implemented with a well-defined empirical procedure. We argue from these results that point-events retain a significant kind of physical objectivity. (shrink)

We introduce LTAG-spinal, a novel variant of traditional Lexicalized Tree Adjoining Grammar (LTAG) with desirable linguistic, computational and statistical properties. Unlike in traditional LTAG, subcategorization frames and the argument-adjunct distinction are left underspecified in LTAG-spinal. LTAG-spinal with adjunction constraints is weakly equivalent to LTAG. The LTAG-spinal formalism is used to extract an LTAG-spinal Treebank from the Penn Treebank with Propbank annotation. Based on Propbank annotation, predicate coordination and LTAG adjunction structures are successfully extracted. The LTAG-spinal Treebank makes explicit (...) semantic relations that are implicit or absent from the original PTB. LTAG-spinal provides a very desirable resource for statistical LTAG parsing, incremental parsing, dependency parsing, and semantic parsing.

Health systems and clinicians rely on the evidence from trials to determine treatment, and patients rely on it to decide which courses of care to undertake. Many of these stakeholders presume that the careful review of individual studies is enough to address the ethical and scientific questions that arise in clinical trials. In what follows, however, we demonstrate that explicit consideration of trial portfolios—series of trials that are interrelated (...) by a common set of objectives—is crucial. the ethical acceptability and evidentiary probity of individual trials can change depending on the characteristics of the portfolios in which they are embedded. Second, how trial portfolios are composed, how well they are coordinated, and how efficiently they use information determines the balance of risks and benefits they present as well as their different prospects for generating socially valuable information; these three factors also raise distinct questions of justice.

This book presents the results of an experiment in interdisciplinary collaboration to clarify theories of morality and anthropology and philosophy, showing how each may be enriched by borrowing from the other. Pooling the resources and methods of their respective fields-anthropology and philosophy-May and Abraham Edel examine the wide range of moral differences in the world "to establish 'coordinates' for the more systematic mapping of particular moralities, to explore more explicitly the relations of morality to cultural patterns and social processes, and (...) to see how philosophic issues of ethical theory become refined and reformulated when their cultural content is made manifest." The book contains an implicit suggestion that the anthropologist should focus on morality as an independent area of study and that the philosopher should stop treating morality in isolation. Anthropology tends to include morality as an incidental part of other inquiries. Philosophy, on the other hand, tends to cut morality off from the framework of psychological and cultural processes; the result is a kind of deadlock in ethical theory. The Edels observe that to develop a working concept of morality at least as well developed as that furnished for religion, anthropology can benefit from philosophic methods of analyzing concepts and from philosophical ways of conceptualizing problems of ethical theory. On the other hand, philosophy can use the methods of anthropology, to approach morality in more meaningful terms. This study is not addressed only to professionals; its aim, rather, is to "provide an orientation to morality itself in a world in which human problems are becoming extremely complex and have to be confronted directly as moral.".

When seeking to coordinate in a game with imperfect information, it is often relevant for a player to know what other players know. Keeping track of the information acquired in a play of infinite duration may, however, lead to infinite hierarchies of higher-order knowledge. We present a construction that makes explicit which higher-order knowledge is relevant in a game and allows us to describe a class of games that admit coordinated winning strategies with finite memory.

This article explores the networking activities of Count Nikolai Rumiantsev and Adam von Krusenstern, his close collaborator. The visionary Russian statesman and the celebrated navigator were deeply involved in northern exploration. They funded and organized a circumnavigating voyage by the brigRurikin 1815–18, with the explicit goals of searching for a northern passage between Eurasia and North America and conducting a series of scientific investigations in the Bering Strait region. This private exploratory enterprise profoundly influenced the exchange of information and (...) reconfigured both local and global networks of knowledge. Based on an analysis of private correspondence, printed accounts and journal articles related to theRurik's expedition, this study sheds light on how this transnational network of actors emerged and functioned, and how it promoted a lively circulation of information about exploration in the Bering Strait region in the 1810s–1820s. I argue that a complex interplay of geopolitical and intellectual competition, with exchanges, collaborations and coordination among various actors (e.g. patrons, navigators, scholars, entrepreneurs and publishers), stimulated further research on the global ocean's northern spaces and laid the foundations of marine science.

The symplectic quantization scheme proposed for matter scalar fields in the companion paper (Gradenigo and Livi, arXiv:2101.02125, 2021) is generalized here to the case of space–time quantum fluctuations.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Existence and the Good: Metaphysical Necessity in Morals and Politics by Franklin I. GamwellWilliam MeyerExistence and the Good: Metaphysical Necessity in Morals and Politics FRANKLIN I. GAMWELL Albany: State University of New York Press, 2011. 219 pp. $24.95In the current era, a few prominent philosophers have called into question the antiteleological tendencies of modern thought. For instance, Thomas Nagel argues that we should reject the antiteleology of science (...) and its “comprehensive, speculative world picture” of “reductive materialism” (Mind and Cosmos, Oxford 2012, 4). As a nontheist, Nagel proposes a “natural teleology” as a secular alternative to theism and to the nonteleology of science as a way to offer a more intelligible and holistic understanding of existence; yet he admits at one point: “Without God, it is unclear what we should aspire to harmony with” (Secular Philosophy & the Religious Temperament, Oxford 2010, 6). With less notoriety but with greater insight, Franklin Gamwell challenges not only modernity’s nonteleology but also its postmetaphysical outlook. By developing a neoclassical or process form of metaphysical theism informed by the works of Charles Hartshorne and Alfred North Whitehead, Gamwell spells out with thoughtful clarity what we should aspire to harmonize with in our individual and collective lives.Focusing on moral and political theory, Gamwell demonstrates that a coherent understanding of ethics (The Divine Good: Modern Moral Theory and the Necessity of God, HarperSanFrancisco, 1990) and politics (Democracy on Purpose: Justice and the Reality of God, Georgetown University Press, 2000) presupposes a neoclassical metaphysical teleology. Here, in Existence and the Good, he offers [End Page 228] a more concise, refined, and integrated formulation of these previous arguments as well as new engagements with important thinkers such as Martin Heidegger and Jeffrey Stout.Gamwell pursues metaphysics in both a “strict” and a “broad” sense: the former refers to critical reflection on the most general characteristics of existence as such, while the latter refers to reflection on the necessary conditions of existence with understanding (17–19). Beginning with the former, he argues that metaphysics properly conceived––in terms of becoming rather than being––is a valid and essential enterprise because “something exists” is necessarily true while “nothing exists” cannot possibly be true (25). He then seeks to show that metaphysics in a broad sense includes metaphysics in the strict sense because existence with understanding necessarily presupposes a metaphysical telos. Toward this end, he engages Heidegger on the metaphysics of subjectivity (chap. 2). Whereas the later Heidegger maintains that all understandings of totality are wholly dependent upon some lifeworld, Gamwell counters that “totality is prior to meaning” because “exemplifications of subjectivity are constituted by prior or nonconscious relations to an order of actualities and possibilities” (49).In chapter 3 Gamwell explicates his neoclassical theism by arguing that the metaphysical telos must be an all-inclusive divine individual. Distinct from Hartshorne, he posits that God does not relate to the world merely in terms of an integration of all past actualities but rather “cooccupies the locus of all contemporaries.” Thus, all “worldly enactment localizes the divine” (90). Gamwell offers here a metaphysical version of incarnation: “Localization of the divine means relation to a becoming that cooccupies one’s place in the world and, therefore, means a communion unlike any other, so that God, we may say, is ‘closer than hands or feet.’ As the metaphysical individual, God is literally the one ‘in whom we live and move and have our being’” (92).Gamwell concludes by engaging Stout on the underlying necessity of metaphysics for democracy. Whereas Stout offers an “ethics without metaphysics” in the form of a “specific pragmatism,” which holds that citizens can coordinate actions on the basis of “moral norms [that] are entirely creatures of historically located social practices” (134), Gamwell maintains that democracy requires “a metaphysical pragmatism,” because “the practice of democratic discourse itself, as all human practices, implies the necessary principle or principles of morality” (146). The key distinction here is between implicit and explicit: Gamwell submits that democracy implicitly presupposes the divine metaphysical telos because that telos is rooted in the very character of reality as such. However, this does not mean that citizens must explicitly recognize or hold... (shrink)

We analyzed whether institutions training physicians and advanced practice registered nurses have conflict of interest policies specific to pharmaceutical relationships and if present do such policies extend to students, other clinicians, personnel, sites, and curriculum. The 2014 Association of Academic Health Centers list of US members identified 65 eligible universities. A 10-item web-based survey was distributed to potential participants. Initial contact was to institutional Directors of Nursing Research, with sequential contacts if no response to Nursing Deans or Department Chairs, Clinical (...) Placement Coordinators, Institutional Research Board Directors, Bioethics Departments, and Legal Counsel. Contacts received 2 email reminders before initiating the next level of contact. Reminder postcards were sent to Dean or Department Chair non-responders. 20 institutions fully completed the survey, a 30% response. Most reported COIP for continuing education or industry funded speaking but 40.5% were "unsure" or "unclear" whether this included curriculum. 55.6% were "unsure" or "did not know" if preceptors were included. Website confirmation noted COIP most frequently covered research funding or trials or gifts and meals. Policies least frequently covered curriculum. 25% included all clinicians in their COIP. No institution covered clinical preceptors unless they were employees. Gaps exist in knowledge of COIP and their scope related to the education of nurse prescribers. While most policies cover research funding or trials in accordance with federal law, they are not explicit or known regarding their extension to nonphysician clinicians, curriculum, or preceptors.

This paper explicates how we might positively understand the distinctive, nonconceptual experience of our own actions and experiences by drawing on insights from a radically enactive take on phenomenal experience. We defend a late-developing relationalism about the emergence of explicit, conceptually based self-awareness, proposing that the latter develops in tandem with the mastery of self-reflective narrative practices. Focusing on the case of human newborns, Sect. 1 reviews and rejects claims that the capacities of actors to keep track of aspects (...) of themselves—e.g. their bodies, body parts, movements, activities, actions and experiences—when coordinating what they do equates to or is best explained by positing minimal, tacit awareness of their experiences as their own. Section 2 then considers and resists more familiar arguments, based on the so-called reflexivity thesis, that take such minimal self-awareness to be implied wherever there is any kind of phenomenal experience. In place of these ideas, we promote an alternative proposal of what is involved when agents keep track of aspects of themselves, drawing on a radically enactive conception of basic experience. Section 3 concludes by proposing that our first conceptual, explicit sense of self is something that only arrives on the scene once we become able to hold our own—through the support of others—in discursive, narrative practices that give us a conceptual grip on what it is to be a temporally extended self that persists over time.

Strategic leadership and corporate sustainability have recently come together in conspicuously explicit fashion through the emergence of top management team positions with dedicated corporate sustainability responsibilities. These TMT positions, commonly referred to as “Chief Sustainability Officers,” have found their way into the upper echelons of many of the world’s largest corporations alongside more traditional TMT positions including the CEO and CFO. We explore this phenomenon and consider the following two questions: Why are corporate sustainability positions being installed to the (...) TMT?What effects do corporate sustainability TMT positions have at their organizations? We consider these questions through strategic leadership and neoinstitutional theoretical frameworks. Through the latter, we also engage with Weberian considerations of bureaucracy. We find that the reasons why corporate sustainability TMT positions are installed can be in response to a crisis at the corporation for which its legitimacy is challenged. We also find the corporate sustainability TMT position can be installed proactively in an effort to realize external opportunities that may have otherwise gone unrealized without concerted attention and coordination afforded by a strategic level position. Regarding effects, we determine the position can relate to the establishment of bureaucratic structures dedicated to corporate sustainability within the corporation through which formalized processes and key performance indicators to drive corporate sustainability performances are established. In the face of our finding that many corporate sustainability TMT positions are being removed despite having only relatively recently been introduced to their respective TMTs, we find that the successful implementation of bureaucratic machinery can help considerations to sustainability extend beyond the tenure of a corporate sustainability position within the TMT.

In this paper, we introduce the concept of N-dimensional generalized Minkowski space, i.e., a space endowed with a metric tensor, whose coefficients do depend on a set of non-metrical coordinates. This is the first of a series of papers devoted to the investigation of the Killing symmetries of generalized Minkowski spaces. In particular, we discuss here the infinitesimal-algebraic structure of the space-time rotations in such spaces. It is shown that the maximal Killing group of these spaces is the direct product (...) of a generalized Lorentz group and a generalized translation group. We derive the explicit form of the generators of the generalized Lorentz group in the self-representation and their related, generalized Lorentz algebra.

The last two decades have witnessed a crescendo of allegations that clinical translation is rife with waste and inefficiency. Patient advocates argue that excessively demanding regulations delay access to life‐saving drugs, research funders claim that too much basic science languishes in academic laboratories, journal editors allege that biased reporting squanders public investment in biomedical research, and drug companies (and their critics) argue that far too much is expended in pharmaceutical development.But how should stakeholders evaluate the efficiency of translation and proposed (...) reforms to drug development? Effective reforms require an accurate model of the systems they aspire to improve—their components, their proper functions, and their pathologies. However, there is currently no explicit and well‐developed model of translation for evaluating such criticisms.In what follows, we offer an explicit model of clinical translation. Many discussions of clinical translation and its pathologies presume that its main output is tangible: new drugs, vaccines, devices, and diagnostics. We disagree. We argue that the principal output of clinical translation is information—in particular, information about the coordinated set of materials, practices, and constraints needed to safely unlock the therapeutic or preventive activities of drugs, biologics, and diagnostics. To develop this information calls for a process far different from a simple linear progression of clinical trials; it requires exploratory sampling of many different elements in this set. Our model points to some limitations and liabilities of influential proposals for reforming research. It also reveals some underrecognized opportunities for improving the efficiency of clinical translation. (shrink)

This article uses the concept of partial organization to examine how organizing principles can facilitate the effective operation of networked forms of corruption. We analyze the case study of a corruption network in the South Korean maritime industry in terms of how it operated by selectively appropriating practices normally associated with formal bureaucratic organizations. Our findings show that organizational elements built into the corruption network enabled coordination of corruption activities and served to distort and override practices within member organizations. (...) The network was primarily organized through the hierarchical organization of a bounded and controlled set of members and, to a lesser extent, through processes of monitoring and sanctions. Given its clandestine nature, the network avoided the use of explicit rules to govern behavior, instead relying on habituated routines to ensure consistent and predictable action from members. We find that organizational elements were rescinded when the corruption network was exposed after the sinking of a passenger ferry, the Sewol. By rolling back its hierarchical organization and reverting to core relationships, the corruption network sought to preserve its center. The article illustrates the explanatory value of studying how the activities of corruption networks are enabled and adapt to existential challenges through partial organization. (shrink)

This thesis investigates two main issues concerning the behavior of rational agents, preference dynamics and agent diversity. -/- We take up two questions left aside by von Wright, and later also the multitude of his successors, in his seminal book Logic of Preference in 1963: reasons for preference, and changes in preference. Various notions of preference are discussed, compared and further correlated in the thesis. In particular, we concentrate on extrinsic preference. Contrary to intrinsic preference, extrinsic preference is reason-based, i.e. (...) one's preference for one option over another has a reason. A logical model is proposed and its properties are determined. Dynamics come in naturally, since reasons for the preferences can change. Logical systems and formal results regarding dynamical preference change are then presented. -/- Preference arises from comparisons between alternatives. A first option is to compare situations. Abstractly speaking, preferences are in this case between propositions, viewed as sets of possible worlds. The reasons can then be based on a `betterness' relation over possible worlds. Propositional preference arises as a lift from this primitive relation. A standard modal logical approach is taken and we use a modality for the betterness relation in the language. We then model preference change by techniques from dynamic epistemic logic (DEL), where a typical action, e.g. a suggestion or a command can change the betterness ordering of the worlds, and thereby the propositional preference. Dynamic reduction axioms are obtained to encode exactly how such a change takes place. We obtain a complete dynamic preference logic. -/- A second option is to compare objects as such. Concretely, properties of the objects often determine the preference over the objects. Properties are now the reasons. Inspired by Optimality Theory (OT), we propose a priority sequence, an ordering of properties. Various ways of getting a preference from the priority sequence are investigated, though we mostly follow the OT approach. We use a fragment of first-order logic to describe the situation. Here, on the dynamic side, it is priority change that leads to preference change. Using the DEL methodology again we propose a complete set of reduction axioms concerning the possible dynamic operations on priority sequences. -/- Not surprisingly, the above two views are closely related. After all, possible worlds can be thought of as objects! On the basis of a systematic comparison of the two views, we develop a two level perspective, in which the models themselves are structured in layers. In particular, correspondence results between the changes at the level of the possible worlds and the changes at the level of the priority sequences are proved. We end up by sketching a two-level preferential predicate logic to describe more complex circumstances in which situations and objects are compared simultaneously. -/- But we do not see this as the whole story. Preference does not live by itself, it is often intermingled with epistemic notions of knowledge and belief. One can have different intuitions about how this entanglement operates. A few options are discussed, and proposals for logical models are presented. When moving to dynamics, we now see a picture of knowledge update, belief revision and preference change taking place symbiotically, often unconsciously as in real life. -/- The resulting picture in the thesis is one of agents that process information and adjust beliefs and preferences in many different ways. There is no logically prescribed unique norm for doing this. The second part of the thesis takes this general phenomenon of diversity of agents as its focus, since it raises many issues for logical systems and the idealized agents which they normally presuppose. In reality, agents can differ across a wide spectrum of cognitive abilities and habits: in their memory capacity, observation power, inferential power, introspective ability, and revision policies when facing new information. -/- Two kinds of agents, perfect recall agents, and memory-free agents are studied thoroughly, in the setting of playing games. We show how current dynamic logics can be `parametrized' to allow for this memory diversity, with new characterizations of agent types resulting in complete dynamic-epistemic logics. The other dimension of the reality of diverse agents is that, however different they are, they often do manage to coordinate with each other successfully. While this theme has been prominent in game theory and multi-agent systems, it has received hardly any attention in logic. We analyze this interaction between different agents by looking at concrete scenarios which model their types explicitly. -/- Finally, we analyze the issue of agent diversity in its generality, discussing what dynamic logics would have to look like to become a full-fledged account of agents of different capacities and tendencies that pursue and sometimes achieve their goals in irreducibly social settings. -/- .

In this paper, we continue the study of the Killing symmetries of an N-dimensional generalized Minkowski space, i.e., a space endowed with a metric tensor, whose coefficients do depend on a set of non-metrical coordinates. We discuss here the finite structure of the space–time rotations in such spaces, by confining ourselves to the four-dimensional case. In particular, the results obtained are specialized to the case of a “deformed” Minkowski space M_4, for which we derive the explicit general form of (...) the finite rotations and boosts in different parametric bases.
