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.

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.

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)

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.

Guilt is a powerful emotion that is known to influence ethical decision-making. Nevertheless, the role of guilt cognitions in influencing restorative behaviour following an unethical action is not well understood. Guilt cognitions are interrelated beliefs about an individual’s role in a negative event. We experimentally investigate the joint impact of three guilt cognitions—responsibility for a decision, justification for a decision, and foreseeability of consequences—on a taxpayer’s decision to make a tax amnesty disclosure. Tax amnesties encourage delinquent taxpayers to self-correct to (...) avoid severe penalties that would result if their tax evasion were discovered. Our findings suggest a three-way interaction effect such that taxpayers are likely to make tax amnesty disclosures when they foresee that they will be caught by the tax authority, unless they can diffuse responsibility for their evasion and justify their evasion. Implications for tax policy and tax professionals are discussed. (shrink)

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)

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.

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)

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.

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.

How do we theorize and analyze the structural power of finance when global capitalism itself undergoes constant and profound structural transformation? The literature continues to assume that the source of financial structural power is its unique ability to provide credit to the real economy, playing a crucial role in meeting the investment imperative. But recent research documents that most financial market activities no longer facilitate productive investment and can even be a drag on economic development. If the financial sector's primary (...) role is not to support productive investments, then on what basis does it continue to hold structural power? The contributions to this special issue engage with how decades of financialization have transformed the basis of structural power toward alternative functions that have gone unnoticed in the existing literature. These include household and real estate lending that fuels consumption-led growth, concentration and expansion of financial institutions as tools of geo-economic strategy, financing current account deficits that facilitate global imbalances, and wealth preservation that bolsters inequality.

We study the sources of resistance to change among firms in the Canadian petroleum industry in response to a shift in societal level logics related to corporate environmental performance. Despite challenges to its legitimacy as a result of poor environmental performance, the Canadian petroleum industry was divided as to how to respond, with some members ignoring the concerns and resisting change (i.e., laggards) while others took action to ensure continued legitimacy (i.e., leaders). We examine why organizations within the same institutional (...) field responded differently, delaying the industry response. We found that one population of firms was aligned with increasing pressures from its stakeholders for improved environmental performance, and the other was influenced by local cultural, political, and economic ideals less demanding of environmental actions. Our results reveal that several factors both at the institutional field level and the organizational level affected how these two populations reacted to a changing societal logic. Implications for theory, practice, and future research are discussed. (shrink)

Risk prediction in emergency medicine (EM) holds unique challenges due to issues surrounding urgency, blurry research-practise distinctions, and the high-pressure environment in emergency departments (ED). Artificial intelligence (AI) risk prediction tools have been developed with the aim of streamlining triaging processes and mitigating perennial issues affecting EDs globally, such as overcrowding and delays. The implementation of these tools is complicated by the potential risks associated with over-triage and under-triage, untraceable false positives, as well as the potential for the biases of (...) healthcare professionals toward technology leading to the incorrect usage of such tools. This paper explores risk surrounding these issues in an analysis of a case study involving a machine learning triage tool called the Score for Emergency Risk Prediction (SERP) in Singapore. This tool is used for estimating mortality risk in presentation at the ED. After two successful retrospective studies demonstrating SERP’s strong predictive accuracy, researchers decided that the pre-implementation randomised controlled trial (RCT) would not be feasible due to how the tool interacts with clinical judgement, complicating the blinded arm of the trial. This led them to consider other methods of testing SERP’s real-world capabilities, such as ongoing-evaluation type studies. We discuss the outcomes of a risk–benefit analysis to argue that the proposed implementation strategy is ethically appropriate and aligns with improvement-focused and systemic approaches to implementation, especially the learning health systems framework (LHS) to ensure safety, efficacy, and ongoing learning.

Abstract:Therapeutic misconception (TM)—when clinical research participants fail to adequately grasp the difference between participating in a clinical trial and receiving ordinary clinical care—has long been recognized as a significant problem in consent to clinical trials. We suggest that TM does not primarily reflect inadequate disclosure or participants’ incompetence. Instead, TM arises from divergent primary cognitive frames. The researchers’ frame places the clinical trial in the context of scientific designs for assessing intervention efficacy. In contrast, most participants have a cognitive frame (...) that is personal and focused primarily on their medical problems. To illustrate this, we draw on interview material from both clinical researchers and participants in clinical trials. We suggest that reducing TM requires encouraging subjects to adjust their frame, not just add information to their existing frame. What is necessary is ascientific reframingof participation in a clinical trial. (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.

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)

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)

As a preliminary step to beginning to assess the usefulness of clinical vignettes to measure ethical sensitivity in undergraduate medical students, five clinical vignettes with seven to nine ethical issues each were created. The ethical issues in the vignettes were discussed and outlined by an expert panel. One randomly selected vignette was presented to first, second and third year students at the University of Toronto as part of another examination. The students were asked to list the issues presented by the (...) patient problem. Responses from 281 students were obtained. These students identified an average of 2.72 ethical issues per vignette. Each response was classified under the domains of autonomy, beneficence and justice. Comparisons were made between classes and between vignettes. There was considerable variation between classes and the responses to different vignettes seem to indicate that different vignettes measure the various domains in different ways. It does appear that the use of vignettes is one way to measure aspects of ethical sensitivity in medical students but more study is required to clarify exactly what is being measured. (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.

Veritists maintain that true belief and only true belief is of fundamental epistemic value. They very often go on to derive epistemic norms based on considerations about what promotes this value. A standard objection is that many truths are pointless: there is no value in believing them. In response, veritists often distinguish between significant and insignificant truths, holding that the former are much more valuable (perhaps even incomparably more valuable) than the latter. But critics cry foul: veritists who say this (...) give up on their claim that it is true belief per se that is of fundamental epistemic value. In this paper I evaluate this dispute by comparing it to the well known dispute over J.S. Mill’s doctrine of higher and lower pleasures. I conclude that the veritist can escape the objection, but that the escape route breeds a new, and different problem. (shrink)

An instrument to assess 'ethical sensitivity' has been developed. The instrument presents four clinical vignettes and the respondent is asked to list the ethical issues related to each vignette. The responses are classified, post hoc, into the domains of autonomy, beneficence and justice. This instrument was used in 1990 to assess the ethical sensitivity of students in all four medical classes at the University of Toronto. Ethical sensitivity, as measured by this instrument, is not related to age or grade-point average. (...) Sensitivity increases between the 1st and 2nd year and then decreases throughout the rest of undergraduate medical training, such that the 4th-year students identify fewer issues than those entering medical school. Students expressing a career choice of family medicine identify more issues than their peers. Several problems with the use of the instrument and the interpretation of the data were found. Nonetheless, these findings, if reproducible, are important and their meaning needs further discussion. (shrink)
