Modeling work by Brian Skyrms and others in recent years has transformed the theoretical role of David Lewis's 1969 model of signaling. The latter can now be understood as a minimal model of communication in all its forms. In this article, we explain how the Lewis model has been generalized, and consider how it and its variants contribute to ongoing debates in several areas. Specifically, we consider connections between the models and four topics: The role of common interest in communication, (...) signaling within the organism, meaning, and the evolution of human communication and language.

Multiple measures of decision-making under uncertainty (e.g. jumping to conclusions (JTC), bias against disconfirmatory evidence (BADE), win-switch behavior, random exploration) have been associated with delusional thinking in independent studies. Yet, it is unknown whether these variables explain shared or unique variance in delusional thinking, and whether these relationships are specific to paranoia or delusional ideation more broadly. Additionally, the underlying computational mechanisms require further investigation. To investigate these questions, task and self-report data were collected in 88 individuals (46 healthy controls, (...) 42 schizophrenia-spectrum) and included measures of cognitive biases and behavior on probabilistic reversal learning and explore/exploit tasks. Of those, only win-switch rate significantly differed between groups. In regression, reversal learning performance, random exploration, and poor evidence integration during BADE showed significant, independent associations with paranoia. Only self-reported JTC was associated with delusional ideation, controlling for paranoia. Computational parameters increased the proportion of variance explained in paranoia. Overall, decision-making influenced by strong volatility and variability is specifically associated with paranoia, whereas self-reported hasty decision-making is specifically associated with other themes of delusional ideation. These aspects of decision-making under uncertainty may therefore represent distinct cognitive processes that, together, have the potential to worsen delusional thinking across the psychosis spectrum.

Some organisations make vaccination a condition of employment. This means prospective employees must demonstrate they have been vaccinated (eg, against measles) to be hired. But it also means organisations must decide whether _existing_ employees should be expected to meet newly introduced vaccination conditions (eg, against COVID-19). Unlike prospective employees who will not be _hired_ if they do not meet vaccination conditions, existing employees who fail to meet new vaccination conditions risk being _fired_. The latter seems worse than the former. Hence, (...) objections to vaccination mandates commonly centre on the harms that will be visited on existing employees who are unwilling to be vaccinated. However, because this objection does not necessarily entail the claim that vaccination is unnecessary for the effective and safe performance of certain jobs, those making this objection should have less of an objection, or no objection at all (at least on these grounds), to introducing vaccination requirements in some cases for _prospective_ employees. Yet, in this paper, I shall argue that if one has reason to believe vaccination requirements can be justified for prospective employees, one should also believe they are justified for existing employees _despite_ any asymmetry in consequences experienced by the two groups. As a consequence, common objections made against vaccination mandates grounded solely in the harms that may be experienced by existing employees who are unwilling to be vaccinated should be considered unpersuasive.

My interest in gathering together a collection of this sort was generated by a fortuitous combination of historical studies under Professor Keith Lehrer and studies in cognitive science under Professor R. Michael Harnish at the University of Arizona. Work on the volume began there while I was an instructor in the Department of Linguistics and was greatly encouraged by participants in the Faculty Seminar on Cognitive Science chaired by Professor Lance J. Rips. I wish to express my appreciation to all (...) of these and to many other individuals with whom I discussed the possibility of contribution to this work. I am especially grateful to the authors of the essays included here, as they showed more patience than I could have hoped for in seeing me through a number of uncertain stages in development of the project. My thanks are also due to my colleague Charles Reid for assistance in reviewing submissions, to Tim McFadden for computer resources, and again, to Keith Lehrer for continuing advice in arrangements for publication. Financial support for manuscript preparation was provided in part under University Research Grant No. 617 from the University Research Council, Youngstown State University. (shrink)

In the recent past, several papers have pointed to the possibility that tumour removal generates a permissive environment in which tumour growth is potentiated. This phenomenon has been coined “perioperative tumour growth” and whilst it represents a departure in terms of our attitude to the surgical process, this concept was first hinted at by Paget1Sir James Paget (1814–1899) was a surgeon and physiologist who is widely held (along with Rudolph Virchow) to be the father of the science of pathology. Paget (...) described Paget's disease of the nipple as well as Paget's disease of bone. himself. Despite this, the time interval immediately before and after cancer surgery (i.e. the perioperative period) remains an underutilised interval during which chemotherapeutic regimens are rarely implemented. Herein, we present a summarised review of the literature that supports the concept that tumour removal may potentiate the growth of residual neoplastic disease. We also outline current knowledge regarding underlying mechanisms and in this manner highlight potential therapeutic entry points. Finally, we emphasise the urgent need for trials of agents that could protect patients against the harmful host–tumour interactions that may occur during the perioperative period.

This paper takes the case of the proposed building of the Traveston dam on the Mary River in Australia to examine the ways postcolonial power relations are played out in city/regional relationships to further the interests of the city. Postcolonialism is concerned with unravelling multiple histories of colonialism, and identifying the reproduction, contestation, ambivalence and transformation of modes of domination and subordination in colonial relations. Political contingencies and contestations by residents, farmers, traditional Indigenous owners and environmentalists seeking to protect endangered (...) species are examined to highlight the dominance of Western anthropocentric, technocentric, and eurocentric epistemologies in political, ecological, environmental, biotheical debates.

The manufacturing industry is evolving rapidly, becoming more complex, more interconnected, and more geographically distributed. Competitive pressure and diversity of consumer demand are driving manufacturing companies to rely more and more on improved knowledge management practices. As a result, multiple software systems are being created to support the integration of data across the product life cycle. Unfortunately, these systems manifest a low degree of interoperability, and this creates problems, for instance when different enterprises or different branches of an enterprise interact. (...) Common ontologies (consensus-based controlled vocabularies) have proved themselves in various domains as a valuable tool for solving such problems. In this paper, we present a consensus-based Additive Manufacturing Ontology (AMO) and illustrate its application in promoting re-usability in the field of dentistry product manufacturing. (shrink)

Research conducted during epidemics may warrant adaptations or adaptive designs owing to practical constraints, time pressures, uncertainty, the importance of flexibility, and the potential for research to detract from epidemic response. Adapting research entails choosing different research designs or methods if research goals, contexts or constraints justify or require a different approach. Adaptive research, by contrast, is a type of research that prospectively plans for modifications after research has been initiated, while maintaining the validity and integrity of the research. While (...) adaptation and adaptive designs introduce an important degree of flexibility to research conducted during epidemics and help to address research objectives and constraints, adaptation and adaptive designs require close ethical scrutiny and are no different from other research in that they are expected to align with universally accepted ethical standards. Important ethical questions exist regarding the conditions that justify adaptations to research, the kinds of adaptive research designs that can be ethically justified, and how ethics review bodies ought to evaluate such novel approaches to research in epidemic contexts. The five cases included in this chapter prompt reflection on the ethical considerations and implications of adapting research in response to epidemic-related risks and the public health measures deployed in response to those risks, as well as the ethical implications of not adapting research in such contexts. These cases also highlight ethical questions and issues arising during the conduct of adaptive trials, including when treatments under study, treatment doses, sample size, and other study features are reviewed in response to evolving evidence. This chapter invites reflection on these key ethical dimensions when considering adaptive designs and adaptations to standard research procedures during epidemics. What these cases make clear is that adaptive designs and adaptations to research do not reduce the need for rigorous scientific evaluation and adherence to universal ethical standards, and must be explicitly ethically justified and reviewed through transparent and inclusive processes.

Disaster response is a highly collaborative and critical process that requires the involvement of multiple emergency responders (ERs), ideally working together under a unified command, to enable a rapid and effective operational response. Following the 9/11 and 11/13 terrorist attacks and the devastation of hurricanes Katrina and Rita, it is apparent that inadequate communication and a lack of interoperability among the ERs engaged on-site can adversely affect disaster response efforts. Within this context, we present a scenario-based terrorism case study to (...) highlight the challenges of operational disaster command and response. In this article, which is based on the French emergency response doctrine, we outline a semantics-based common operational command system that is designed to guarantee an efficient information flow among ERs. Our focus is on offering to all ERs, a real-time operational picture of the situation in order to enable multilevel coordination among firefighters, police, healthcare units, public authorities, and other stakeholders. Our approach consolidates information to promote timely sharing of data among ERs. The proposed system is based on an ontology that has been developed to represent the different types of knowledge on the part of ERs, providing a shared vocabulary that covers a variety of interoperability concerns.

In my contribution to this volume, I (BHS) comment on on the stultifying rhetoric of contemporary analytic moral theory as illustrated in Judith Jarvis Thomson's Tanner Lectures, with particular reference to Thomson's anxieties about the moral relativism exhibited by college freshman and to her efforts--quite strained, in my view, and inevitably unsuccessful--to demonstrate the existence of objective judgments in matters of morality and taste .

Achieving space situational awareness requires, at a minimum, the identification, characterization, and tracking of space objects. Leveraging the resultant space object data for purposes such as hostile threat assessment, object identification, and conjunction assessment presents major challenges. This is in part because in characterizing space objects we reference a variety of identifiers, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, operational processes, operational statuses, and so forth, which tend to be defined in highly heterogeneous and sometimes inconsistent (...) ways. The Space Domain Ontologies are designed to provide a consensus-based realist framework for formulating such characterizations in a way that is both consistent and computable. Space object data are aligned with classes and relations in a suite of ontologies built around the existing Space Object Ontology. They are stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space situational awareness and the needs of spacecraft operators and analysts. This paper provides an overview of the Space Domain Ontologies and their development and use. It presents the motivation for and advantages of the Space Domain Ontologies, including the benefits they provide for enhancing and maintaining long-term space situational awareness. (shrink)

In his 2000 book, From Chaos to Coercion: Detention and the Control of Tuberculosis, Richard Coker makes a number of important observations and arguments regarding the use of coercive public health measures in response to infectious disease threats. In particular, Coker argues that we have a tendency to neglect public health threats and then demand immediate action, which can leave policymakers with fewer effective options and may require (or may be perceived as requiring) more aggressive, coercive measures to achieve public (...) health goals. While Coker makes a convincing case as to why we should find it ethically problematic when governments find themselves in this position and resort to coercion, left outstanding is the question of whether this should preclude governments and health authorities from using coercion if and when they do find themselves in this position. In this paper, I argue that, while we should consider it ethically objectionable when governments resort to coercion because they have neglected a public health threat, its causes, and other possible responses to that threat, this should not then necessarily rule out the use of coercion in such circumstances; that there are ethically objectionable antecedents for why coercion is being considered should not necessarily or automatically cause us to think coercion in such cases cannot be justified. I address an objection to this argument and draw several conclusions about how governments’ use of coercion in public health should be evaluated. (shrink)

Abstract In light of the complexity of unfolding disasters, the diversity of rapidly evolving events, the enormous amount of generated information, and the huge pool of casualties, emergency responders (ERs) may be overwhelmed and in consequence poor decisions may be made. In fact, the possibility of transporting the wounded victims to one of several hospitals and the dynamic changes in healthcare resource availability make the decision process more complex. To tackle this problem, we propose a multicriteria decision support service, based (...) on the Analytic Hierarchy Process (AHP) method, that aims to avoid overcrowding and outpacing the capacity of a hospital to effectively provide the best care to victims by finding out the most appropriate hospital that meets the victims’ needs. The proposed approach searches for the most appropriate healthcare institution that can effectively deal with the victims’ needs by considering the availability of the needed resources in the hospital, the victim’s wait time to receive the healthcare, and the transfer time that represents the hospital proximity to the disaster site. The evaluation and validation results showed that the assignment of hospitals was done successfully considering the needs of each victim and without overwhelming any single hospital. (shrink)

Functionally graded materials (FGMs) have been used in many different kinds of applications in recent years and have attracted significant research attention. However, we do not yet have a commonly accepted way of representing the various aspects of FGMs. Lack of standardised vocabulary creates obstacles to the extraction of useful information relating to pertinent aspects of different applications. A standard resource is needed for describing various elements of FGMs, including existing applications, manufacturing techniques, and material characteristics. This motivated the creation (...) of the FGM Ontology (FGMO) in 2016. Here, we present a revised and expanded version of the FGM Ontology, which includes enrichments along four dimensions: (1) documenting recent FGMs applications; (2) reorganising the framework to incorporate an updated representation of types of manufacturing processes; (3) enriching the axioms of the ontology; and (4) importing mid-level ontologies from the Common Core Ontologies (CCO) and Product Life Cycle (PLC) Ontologies. The work is being carried out within the framework of the Industry Ontology Foundry (IOF), and the ontology is conformant to Basic Formal Ontology (BFO). (shrink)
