This comprehensive text shows how various notions of logic can be viewed as notions of universal algebra providing more advanced concepts for those who have an introductory knowledge of algebraic logic, as well as those wishing to delve into more theoretical aspects.

We often evaluate belief-forming processes, agents, or entire belief states for reliability. This is normally done with the assumption that beliefs are all-or-nothing. How does such evaluation go when we’re considering beliefs that come in degrees? I consider a natural answer to this question that focuses on the degree of truth-possession had by a set of beliefs. I argue that this natural proposal is inadequate, but for an interesting reason. When we are dealing with all-or-nothing belief, high reliability leads to (...) high levels of truth-possession. However, when it comes to degrees of belief, reliability and truth-possession part ways. The natural answer thus fails to be a good way to evaluate degrees of belief for reliability. I propose and develop an alternative method based on the notion of calibration, suggested by Frank Ramsey, which does not have this problem and consider why we should care about such assessments of reliability even if they are not tied directly to truth-possession.

Given classical (2 valued) structures and and a homomorphism h of onto , it is shown how to construct a (non-degenerate) 3-valued counterpart of . Classical sentences that are true in are non-false in . Applications to number theory and type theory (with axiom of infinity) produce finite 3-valued models in which all classically true sentences of these theories are non-false. Connections to relevant logic give absolute consistency proofs for versions of these theories formulated in relevant logic (the proof for (...) number theory was obtained earlier by R. K. Meyer and suggested the present abstract development). (shrink)

As the COVID-19 pandemic impacts on health service delivery, health providers are modifying care pathways and staffing models in ways that require health professionals to be reallocated to work in critical care settings. Many of the roles that staff are being allocated to in the intensive care unit and emergency department pose additional risks to themselves, and new policies for staff reallocation are causing distress and uncertainty to the professionals concerned. In this paper, we analyse a range of ethical issues (...) associated with changes to staff allocation processes in the face of COVID-19. In line with a dominant view in the medical ethics literature, we claim, first, that no individual health professional has a specific, positive obligation to treat a patient when doing so places that professional at risk of harm, and so there is a clear ethical tension in any reallocation process in this context. Next, we argue that the changing asymmetries of health needs in hospitals means that careful consideration needs to be given to a stepwise process for deallocating staff from their usual duties. We conclude by considering how a justifiable process of reallocating professionals to high-risk clinical roles should be configured once those who are ‘fit for reallocation’ have been identified. We claim that this process needs to attend to three questions that we consider in detail: (1) how the choice to make reallocation decisions is made, (2) what justifiable models for reallocation might look like and (3) what is owed to those who are reallocated.

A growing body of research suggests that follower perceptions of ethical leadership are associated with beneficial follower outcomes. However, some empirical researchers have found contradictory results. In this study, we use social learning and social exchange theories to test the relationship between ethical leadership and follower work outcomes. Our results suggest that ethical leadership is related positively to numerous follower outcomes such as perceptions of leader interactional fairness and follower ethical behavior. Furthermore, we explore how ethical leadership relates to and (...) is different from other leadership styles such as transformational and transactional leadership. Results suggest that ethical leadership is positively associated with transformational leadership and the contingent reward dimension of transactional leadership. With respect to the moderators, our results show mixed evidence for publication bias. Finally, geographical locations of study samples moderated some of the relationships between ethical leadership and follower outcomes, and employee samples from public sector organizations showed stronger mean corrected correlations for ethical leadership–follower outcome relationships.

Individuals frequently make use of the body and environment when engaged in a cognitive task. For example, individuals will often spontaneously physically rotate when faced with rotated objects, such as an array of words, to putatively offload the performance costs associated with stimulus rotation. We looked to further examine this idea by independently manipulating the costs associated with both word rotation and array frame rotation. Surprisingly, we found that individuals’ patterns of spontaneous physical rotations did not follow patterns of performance (...) costs or benefits associated with being physically rotated, findings difficult to reconcile with existing theories of strategy selection involving external resources. Individuals’ subjective ratings of perceived benefits, rather, provided an excellent match to the patterns of physical rotations, suggesting that the critical variable when deciding on-the-fly whether to incorporate an external resource is the participant's metacognitive beliefs regarding expected performance or the effort required for each approach. Implications for metacognition's future in theories of cognitive offloading are discussed. (shrink)

In this paper, we examine the interactive effects of positive affect and perspective-taking on workplace incivility and family incivility, through moral disengagement. We draw from broaden-and-build and moral disengagement theories to suggest a potential negative consequence of positive affect. Specifically, we argue that positive affect increases incivility toward coworkers and spouses through moral disengagement among employees with low, but not high perspective-taking. Data from two time-lagged field studies and one online experiment provide support for our hypotheses. These findings suggest that (...) the beneficial effects of positive feelings are not universal, and the fostering of positive feelings at work might have unintended negative consequences, namely moral disengagement, and increased incivility at work and at home. Implications for theory and research are discussed. (shrink)

One of the most dominant approaches to semantics for relevant (and many paraconsistent) logics is the Routley-Meyer semantics involving a ternary relation on points. To some (many?), this ternary relation has seemed like a technical trick devoid of an intuitively appealing philosophical story that connects it up with conditionality in general. In this paper, we respond to this worry by providing three different philosophical accounts of the ternary relation that correspond to three conceptions of conditionality. We close by briefly discussing (...) a general conception of conditionality that may unify the three given conceptions. (shrink)

This paper addresses the challenge of ethically integrating ChatGPT, a sophisticated AI language model, into K-14 economics education. Amidst the growing presence of AI in classrooms, it proposes the “Evaluate, Reflect, Assurance” model, a novel decision-making framework grounded in normative and virtue ethics, to guide educators. This approach is detailed through a theoretical decision tree, offering educators a heuristic tool to weigh the educational advantages and ethical dimensions of using ChatGPT. An educator can use the decision tree to reach a (...) conclusion on using ChatGPT within the classroom environment by using ethical considerations to promote personalized learning and upholding academic integrity. The paper stresses the importance of ongoing professional development for educators in ethical AI usage and calls for institutional support in this pursuit. It also identifies future research directions, including long-term impact studies of ChatGPT and comparative analyses of various AI tools in economics education, underscoring the paper’s relevance to current educational technology discourse.

Next SectionMaking threats and offers to patients is a strategy used in community mental healthcare to increase treatment adherence. In this paper, an ethical analysis of these types of proposal is presented. It is argued (1) that the primary ethical consideration is to identify the professional duties of care held by those working in community mental health because the nature of these duties will enable a threat to be differentiated from an offer, (2) that threatening to act in a way (...) that would equate with a failure to uphold the requirements of these duties is wrong, irrespective of the benefit accrued through treatment adherence and (3) that making offers to patients raises a number of secondary ethical considerations that need to be judged on their own merit in the context of individual patient care. The paper concludes by considering the implications of these arguments, setting out a pathway designed to assist community mental healthcare practitioners to determine whether making a specific proposal to a patient is right or wrong.

In this paper two different formulations of Robinson's arithmetic based on relevant logic are examined. The formulation based on the natural numbers (including zero) is shown to collapse into classical Robinson's arithmetic, whereas the one based on the positive integers (excluding zero) is shown not to similarly collapse. Relations of these two formulations to R. K. Meyer's system R# of relevant Peano arithmetic are examined, and some remarks are made about the role of constant functions (e.g., multiplication by zero) in (...) relevant arithmetic. (shrink)

The validity of an entailment has nothing to do with whether or not the components are true, false, necessary, or impossible; it has to do solely with whether or not there is a necessary connection between antecedent and consequent. Hence it is a mistake (we feel) to try to build a sieve which will “strain out” entailments from the set of material or strict “implications” present in some system of truth-functions, or of truth-functions with modality. Anderson and Belnap (1962, p. (...) 47). (shrink)

Abstract:Vulnerability is an important criterion to assess the ethical justification of the inclusion of participants in research trials. Currently, vulnerability is often understood as an attribute inherent to a participant by nature of a diagnosed condition. Accordingly, a common ethical concern relates to the participant’s decisionmaking capacity and ability to provide free and informed consent. We propose an expanded view of vulnerability that moves beyond a focus on consent and the intrinsic attributes of participants. We offer specific suggestions for how (...) relational aspects and the dynamic features of vulnerability could be more fully captured in current discussions and research practices. (shrink)

“What is the structure of thought?” is as central a question as any in cognitive science. A classic answer to this question has appealed to a Language of Thought (LoT). We point to emerging research from disparate branches of the field that supports the LoT hypothesis, but also uncovers diversity in LoTs across cognitive systems, stages of development, and species. Our letter formulates open research questions for cognitive science concerning the varieties of rules and representations that underwrite various LoT-based systems (...) and how these variations can help researchers taxonomize cognitive systems.

In the UK, current policies and services for people with mental disorders, including those with intellectual disabilities (ID), presume that these men and women can, do, and should, make decisions for themselves. The new Mental Capacity Act (England and Wales) 2005 (MCA) sets this presumption into statute, and codifies how decisions relating to health and welfare should be made for those adults judged unable to make one or more such decisions autonomously. The MCA uses a procedural checklist to guide this (...) process of substitute decision-making. The personal experiences of providing direct support to seven men and women with ID living in residential care, however, showed that substitute decision-making took two forms, depending on the type of decision to be made. The first process, ‘strategic substitute decision-making’, paralleled the MCA’s legal and ethical framework, whilst the second process, ‘relational substitute decision-making’, was markedly different from these statutory procedures. In this setting, ‘relational substitute decision-making’ underpinned everyday personal and social interventions connected with residents’ daily living, and was situated within a framework of interpersonal and interdependent care relationships. The implications of these findings for residential services and the implementation of the MCA are discussed. (shrink)

Community treatment orders are a legal mechanism to extend powers of compulsion into outpatient mental health settings in certain circumstances. Previous ethical analyses of these powers have explored a perceived tension between a duty to respect personal freedoms and autonomy and a duty to ensure that patients with the most complex needs are able to receive beneficial care and support that maximises their welfare in the longer-term. This empirical ethics paper presents an analysis of 75 interviews with psychiatrists, patients and (...) family carers to show how these ethical considerations map onto the different ways that community treatment orders are used and experienced in practice. A complex and nuanced account of how the requirements to respect patients’ autonomy, to respect patients’ liberty and to act beneficently should be interpreted in order to make judgements about the ethics of community treatment orders is presented. The article argues that, due to such complexity, no general ethical justification for community treatment orders can be provided, but a justification on the basis of the promotion of patients’ autonomy could provide an ethical reason for community mental health practitioners to make use of a community treatment order in some limited circumstances.

Bioethics is gradually becoming an important part of the drive to increase quality healthcare delivery in sub‐Saharan African countries. Yet many healthcare service‐users in Africa are familiar with incidences of questionable health policies and poor healthcare delivery, leading to severe consequences for patients. We argue that the overarching rights‐based ethical administrative framework recently employed by healthcare authorities contributes to the poor uptake and enforcement of current normative tools. Taking Ghana as a case study, we focus on the cultural ethical context (...) and we tease out the concepts of the good and the ethical among the Akan and Bulsa ethnic groups. We point out three tenets towards building a normative framework that can resonate with service‐users and practitioners: ontological communitarianism; empathic humanism; and virtuous character. Finally, we indicate how these core tenets can be dovetailed into building an effective normative framework and into the training of healthcare providers. (shrink)

This paper discusses the implications for public participation in science opened by the sharing of information via electronic media. The ethical dimensions of information flow and control are linked to questions of autonomy, authority and appropriate exploitation of knowledge. It argues that, by lowering the boundaries that limit access and participation by wider active audiences, both scientific identity and practice are challenged in favor of extra-disciplinary and avocational communities such as scientific enthusiasts and lay experts. Reconfigurations of hierarchy, mediated by (...) new channels of information flow, are increasingly visible at the interface between professional and non-professional practice. Setting the scene by surveying the role of the media in defining twentieth-century contexts of lay science, the paper illustrates the appropriation and recuperation of scientific authority being played out in two contemporary models of active public engagement: so-called “citizen science” and varieties of “crowd-sourced science”. Both participatory models are increasingly reliant on information exchange via social media, but may be implemented to support distinctly different societal goals and beneficiaries. (shrink)

A recent study has established that thinkers reliably engage in epistemic appraisals of concepts of natural categories. Here, five studies are reported which investigated the effects of different manipulations of category learning context on appraisal of the concepts learnt. It was predicted that dimensions of concept appraisal could be affected by manipulating either procedural factors or declarative factors. While known effects of these manipulations on metacognitive judgements such as category learning judgements and confidence at test were replicated, procedural factors had (...) no reliable effects on the dimensions of concept appraisal. Effects of declarative manipulations on some forms of concept appraisal were observed. (shrink)

In the human quest for meaning, work occupies a central position. Most adults spend the majority of their waking hours at work, which often serves as a primary source of purpose, belongingness, and identity. In light of these benefits to employees and their organizations, organizational scholars are increasingly interested in understanding the factors that contribute to meaningful work, such as the design of jobs, interpersonal relationships, and organizational missions and cultures. In a separate line of inquiry, scholars of business ethics (...) have examined meaningful work as a moral issue concerning the management of others and ourselves, exploring whether there are definable characteristics of meaningful work to which we have moral rights, and whether there are moral duties to ourselves and others to fulfill those rights. In this article, we examine contemporary developments in both disciplines about the nature, causes, and consequences of meaningful work; we explore linkages between these disciplines; and we offer conclusions and research opportunities regarding the interface of ethical and organizational perspectives on performing and providing meaningful work.

A number of EU institutions and government committees across Europe have expressed interest in developing methods and decision-support tools to facilitate consideration of the ethical dimensions of biotechnology assessment. As part of the work conducted in the EC supported project on ethical tools (Ethical Bio-TA Tools), a number of ethical frameworks with the potential to support the work of public policy decision-makers has been characterized and evaluated. One of these potential tools is the Delphi method. The Delphi method was originally (...) developed to assess variables that are intangible and/or shrouded in uncertainty by drawing on the knowledge and abilities of a diverse group of experts through a form of anonymous and iterative consultation. The method has hitherto been used by a diversity of practitioners to explore issues such as technology assessment, environmental planning, and public health measures. From the original (classical) Delphi, a family of Delphi-related processes has emerged. As a result of the evaluation of the various Delphi processes, it is proposed that the classical method can be further developed and applied as a form of ethical framework to assist policy-makers. Through a series of exercises and trials, an Ethical Delphi has been developed as a potential approach for characterizing ethical issues raised by the use of novel biotechnologies. Advantages and disadvantages of the method are discussed. Further work is needed to develop the procedural aspects of the Ethical Delphi method and to test its use in different cultural contexts. However, utilizing an ethical framework of this type combines the advantages of a methodical approach to capture ethical aspects with the democratic virtues of transparency and openness to criticism. Ethical frameworks such as the Ethical Delphi should contribute to better understanding of and decision-making on issues that involve decisive ethical dimensions. (shrink)

Surrogate (proxy) decision makers must make research decisions for people with dementia who lack decision-making capacity. Proxies’ decision-making processes are minimally understood. We randomly assigned 82 proxies of AD patients to informed consent for one of three hypothetical protocols with differing levels of risk and benefit. Proxies answered questions about potential benefits of the described research to the patient and society, as well as about whether they would enroll their relative and why or why not. Proxies interested in enrolling their (...) relative cited the potential for direct benefit to their relative, altruism, and trust in researchers. Those declining cited risks, inconvenience, and stage of illness. Proxies weighed numerous factors, incorporating both substituted judgment and best interests standards in their decision-making processes. Although further empirical work is needed to understand the influences on and adequacy of proxies’ decision making regarding research, these findings can help inform policy regarding surrogate consent.

Bayesian Epistemology is a general framework for thinking about agents who have beliefs that come in degrees. Theories in this framework give accounts of rational belief and rational belief change, which share two key features: (i) rational belief states are represented with probability functions, and (ii) rational belief change results from the acquisition of evidence. This dissertation focuses specifically on the second feature. I pose the Evidence Question: What is it to have evidence? Before addressing this question we must have (...) an understanding of Bayesian Epistemology. The first chapter argues that we should understand Bayesian Epistemology as giving us theories that are evaluative and not action-guiding. I reach this verdict after considering the popular ‘ought’-implies-‘can’ objection to Bayesian Epistemology. The second chapter argues that it is important for theories in Bayesian Epistemology to answer the Evidence Question, and distinguishes between internalist and externalist answers. The third and fourth chapters present and defend a specific answer to the Evidence Question. The account is inspired by reliabilist accounts of justification, and attempts to understand what it is to have evidence by appealing solely to considerations of reliability. Chapter 3 explains how to understand reliability, and how the account fits with Bayesian Epistemology, in particular, the requirement that an agent’s evidence receive probability 1. Chapter 4 responds to objections, which maintain that the account gives the wrong verdict in a variety of situations including skeptical scenarios, lottery cases, scientific cases, and cases involving inference. After slight modifications, I argue that my account has the resources to answer the objections. The fifth chapter considers the possibility of losing evidence. I show how my account can model these cases. To do so, however, we require a modification to Conditionalization, the orthodox principle governing belief change. I present such a modification. The sixth and seventh chapters propose a new understanding of Dutch Book Arguments, historically important arguments for Bayesian principles. The proposal shows that the Dutch Book Arguments for implausible principles are defective, while the ones for plausible principles are not. The final chapter is a conclusion. (shrink)

Interoception can be broadly defined as the sense of signals originating within the body. As such, interoception is critical for our sense of embodiment, motivation, and well-being. And yet, despite its importance, interoception remains poorly understood within modern science. This paper reviews interdisciplinary perspectives on interoception, with the goal of presenting a unified perspective from diverse fields such as neuroscience, clinical practice, and contemplative studies. It is hoped that this integrative effort will advance our understanding of how interoception determines well-being, (...) and identify the central challenges to such understanding. To this end, we introduce an expanded taxonomy of interoceptive processes, arguing that many of these processes can be understood through an emerging predictive coding model for mind–body integration. The model, which describes the tension between expected and felt body sensation, parallels contemplative theories, and implicates interoception in a variety of affective and psychosomatic disorders. We conclude that maladaptive construal of bodily sensations may lie at the heart of many contemporary maladies, and that contemplative practices may attenuate these interpretative biases, restoring a person’s sense of presence and agency in the world.

ABSTRACT:Re-establishing trust presents a complex challenge for a firm after it commits corporate misconduct. We introduce a new construct, moral salience, which we define as the extent to which the firm’s behavior is morally noticeable to the stakeholder. Moral salience is a function of both the moral intensity of the firm’s behavior and the relational intensity of the firm-stakeholder psychological contract. We apply this moral salience construct to firm misconduct to develop a model of trust repair that is based on (...) goodwill, and moderated by the firm’s stakeholder culture. (shrink)

Late in 1990, the Center for the Study of Ethics in the Professions at Illinois Institute of Technology (lIT) received a grant of more than $200,000 from the National Science Foundation to try a campus-wide approach to integrating professional ethics into its technical curriculum.! Enough has now been accomplished to draw some tentative conclusions. I am the grant's principal investigator. In this paper, I shall describe what we at lIT did, what we learned, and what others, especially philosophers, can learn (...) from us. We set out to develop an approach that others could profitably adopt. I believe that we succeeded. (shrink)
