Purpose Algorithms are in the mainstream media news on an almost daily basis. Their context is invariably artificial intelligence and machine learning decision-making. In media articles, algorithms are described as powerful, autonomous actors that have a capability of producing actions that have consequences. Despite a tendency for deification, the prevailing critique of algorithms focuses on ethical concerns raised by decisions resulting from algorithmic processing. However, the purpose of this paper is to propose that the ethical concerns discussed are limited in (...) scope and suggest that it is not clear what concerns dominate the debate. Design/methodology/approach The paper uses a systematic mapping study approach to review articles appearing in leading UK national papers from the perspective of the ethical concerns over a period of one year. The articles are categorised using a widely cited framework detailing a taxonomy of ethical concerns. The UK context is important because of UK public policy initiatives around AI. Findings The research presented in this paper contributes the first systematic mapping study of articles appearing in leading UK national papers from the perspective of widely accepted ethical concerns such as inscrutable evidence, misguided evidence, unfair outcomes and transformative effects. Originality/value The research presented in this paper contributes the first systematic mapping study of articles appearing in leading UK national papers from the perspective of the ethical concerns. The UK context is important because of UK public policy initiatives around AI. To review the media content from the perspective of ethical concerns, this paper uses the synthesised conceptual map of ethical concerns developed by Mittelstad et al. Given the dominance of that framework, this paper’s contribution is also an important instantiation and experimental validation of using that conceptual map. (shrink)

Halin in 1965 proved that if a graph has [Formula: see text] many pairwise disjoint rays for each [Formula: see text] then it has infinitely many pairwise disjoint rays. We analyze the complexity of this and other similar results in terms of computable and proof theoretic complexity. The statement of Halin’s theorem and the construction proving it seem very much like standard versions of compactness arguments such as König’s Lemma. Those results, while not computable, are relatively simple. They only use (...) arithmetic procedures or, equivalently, finitely many iterations of the Turing jump. We show that several Halin-type theorems are much more complicated. They are among the theorems of hyperarithmetic analysis. Such theorems imply the ability to iterate the Turing jump along any computable well ordering. Several important logical principles in this class have been extensively studied beginning with work of Kreisel, H. Friedman, Steel and others in the 1960s and 1970s. Until now, only one purely mathematical example was known. Our work provides many more and so answers Question 30 of Montalbán’s Open Questions in Reverse Mathematics in 2011. Some of these theorems including ones in Halin in 1965 are also shown to have unusual proof theoretic strength as well. (shrink)

In Information Systems development, resilience has often been treated as a non-functional requirement and little or no work is aimed at building resilience in end-users through systems development. The question of how values and resilience (for the end-user) can be incorporated into the design of systems is an on-going research activity in user-centered design. In this paper we evaluate the relation of values and resilience within the context of an ongoing software development project and contribute a formal model of co-design (...) based on a significant extension of Abstract Design Theory. The formal analysis provides a full and clear-cut definition of the co-design space, its objectives and processes. On the basis of both, we provide an abstract definition of resilient system (for the end-user). We conclude that value-sensitive co-design enforces better resilience in end-users. (shrink)

We establish the decidability of the${{\rm{\Sigma }}_2}$theory of both the arithmetic and hyperarithmetic degrees in the language of uppersemilattices, i.e., the language with ≤, 0, and$\sqcup$. This is achieved by using Kumabe-Slaman forcing, along with other known results, to show given finite uppersemilattices${\cal M}$and${\cal N}$, where${\cal M}$is a subuppersemilattice of${\cal N}$, that every embedding of${\cal M}$into either degree structure extends to one of${\cal N}$iff${\cal N}$is an end-extension of${\cal M}$.

Theorems of hyperarithmetic analysis occupy an unusual neighborhood in the realms of reverse mathematics and recursion-theoretic complexity. They lie above all the fixed iterations of the Turing jump but below ATR $_{0}$. There is a long history of proof-theoretic principles which are THAs. Until the papers reported on in this communication, there was only one mathematical example. Barnes, Goh, and Shore [1] analyze an array of ubiquity theorems in graph theory descended from Halin’s [9] work on rays in graphs. They (...) seem to be typical applications of ACA $_{0}$ but are actually THAs. These results answer Question 30 of Montalbán’s Open Questions in Reverse Mathematics [19] and supply several other natural principles of different and unusual levels of complexity.This work led in [25] to a new neighborhood of the reverse mathematical zoo: almost theorems of hyperarithmetic analysis. When combined with ACA $_{0}$ they are THAs but on their own are very weak. Denizens both mathematical and logical are provided. Generalizations of several conservativity classes are defined and these ATHAs as well as many other principles are shown to be conservative over RCA $_{0}$ in all these senses and weak in other recursion-theoretic ways as well. These results answer a question raised by Hirschfeldt and reported in [19] by providing a long list of pairs of principles one of which is very weak over RCA $_{0}$ but over ACA $_{0}$ is equivalent to the other which may be strong or very strong going up a standard hierarchy and at the end being stronger than full second-order arithmetic.

This article considers the theme of discernment in the tradition of Ignatian spirituality emanating from the Spiritual Exercises of St Ignatius of Loyola, the founder of the Society of Jesus. After a brief introduction which addresses the central problematic of bad influences that manifest themselves as good, the article turns to the life and work of two Jesuits, the 16th C English missionary to India, Thomas Stephens and the 20th C French historian and cultural critic, Michel de Certeau. Both kept (...) up a constant dialogue with local culture in which they sought authenticity in their response to ‘events’, whether a hideous massacre which shaped the pastoral commitment and writing of Stephens in the south of the Portuguese enclave of Goa or the 1968 student-led protests in Paris that so much affected the thinking of de Certeau. Very different in terms of personal background and contemporary experience, they both share in a tradition of discernment as a virtuous response to what both would understand as the ‘wisdom of the Spirit’ revealed in their personal interactions with ‘the other’.

IntroductionThe objectives of this study are to assess and compare differences in the intensity, frequency, and overall severity of moral distress among a diverse group of healthcare professionals.MethodsParticipants from within Baylor Health Care System completed an online seven-point Likert scale (range, 0 to 6) moral distress survey containing nine core clinical scenarios and additional scenarios specific to each participant’s discipline. Higher scores reflected greater intensity and/or frequency of moral distress.ResultsMore than 2,700 healthcare professionals responded to the survey (response rate 18.14 (...) percent); survey respondents represented multiple healthcare disciplines across a variety of settings in a single healthcare system. Intensity of moral distress was high in all disciplines, although the causes of highest intensity varied by discipline. Mean moral distress intensity for the nine core scenarios was higher among physicians than nurses, but the mean moral distress frequency was higher among nurses. Taking into account both intensity and frequency, the difference in mean moral distress score was statistically significant among the various disciplines. Using post hoc analysis, differences were greatest between nurses and therapists.ConclusionsMoral distress has previously been described as a phenomenon predominantly among nursing professionals. This first-of-its-kind multidisciplinary study of moral distress suggests the phenomenon is significant across multiple professional healthcare disciplines. Healthcare professionals should be sensitive to situations that create moral distress for colleagues from other disciplines. Policy makers and administrators should explore options to lessen moral distress and professional burnout that frequently accompanies it. (shrink)

In both academic literature and the media, financial conflicts of interest in human subjects research have come center-stage. The cover of a recent edition of Time magazine features a research subject in a cage with the caption human guinea pigs, signifying perhaps that human research subjects are no more protected from research abuses than are laboratory animals. That magazine issue highlights three well-publicized cases of human subjects research violations that occurred at the University of Oklahoma, the University of Pennsylvania, and (...) Johns Hopkins University.At St. John Medical Center in Tulsa, Oklahoma, a study that was co-sponsored by the University of Oklahoma Health Sciences Center investigated an experimental vaccine for malignant melanoma. In that case, the chair of the university's institutional review board — the committee within each medical institution charged with ethics review of human research projects undertaken at that institution — and the dean of the University's College of Medicine allegedly concealed from both the IRB and the United States Food and Drug Administration a report by an outside consulting firm that had found severe deficiencies with the melanoma vaccine study being conducted at the medical center.

Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models. Scalable, customisable, and ethical solutions can be achieved by working together with relevant stakeholders, including patients, data scientists, and policy makers.

The sudden emergence of the COVID-19 pandemic brought global disruption to every aspect of society including healthcare, supply chain, the economy, and social interaction. Among the many emergent considerations were the safety and public health of the public, patients, essential workers, and healthcare professionals. In certain locations, clinical research was halted—or terminated—in deference to the immediate needs of patient care, and clinical trials focusing on the treatment and prevention of coronavirus infection were prioritized over studies focusing on other diseases. Difficult (...) decisions were made rapidly; flexibility and reconsideration were necessary not only because the intensity and severity of infection varied over time and by locale but also because knowledge of the disease and understanding of its treatment grew. Here we discuss the ethical challenges in decision-making and competing ethical tensions during the pandemic in an effort to advance future preparedness. (shrink)

What is it to deceive someone? And how is it possible to deceive oneself? Does self-deception require that people be taken in by a deceitful strategy that they know is deceitful? The literature is divided between those who argue that self-deception is intentional and those who argue that it is non-intentional. In this study, Annette Barnes offers a challenge to both the standard characterisation of other-deception and current characterizations of self-deception, examining the available explanations and exploring such questions as the (...) self-deceiver's false consciousness, bias, and the irrationality and objectionability of self-deception. She arrives at a non-intentional account of self-deception that is deeper and more complete than alternative non-intentional accounts and avoids the reduction of self-deceptive belief to wishful belief.

Anhedonia is a risk factor for suicide and poor treatment response in depressed individuals. Most evidence-based psychological therapies target symptoms of heightened negative affect instead of deficits in positive affect and typically show little benefit for anhedonia. Viewing positive scenes through virtual reality has been shown to increase positive affect and holds great promise for addressing anhedonic symptoms. In this pilot study, six participants with clinically significant depression completed 13 sessions of exposure to positive scenes in a controlled VR environment. (...) Significant decreases were found in self-reported anhedonia, depression, anxiety, and impairments in functioning from baseline to 1-month follow-up. Negative affect decreased over all 13 sessions, and positive affect increased over sessions 8–13. Results suggest that positive experiences in VR may be a novel avenue for the treatment of anhedonia in depressed individuals. (shrink)

In Chapter 9 of the first book of the Metaphysics Aristotle criticizes “those who posit the Ideas as causes”. His second group of criticisms urges that “the ways in which we try to prove that the forms exist” are unsatisfactory, and he enumerates five such ‘ways’. Alexander of Aphrodisias, in his commentary on the passage, offers to explain in more detail what the five ways were and why each is a cul-de-sac. Gail Fine’s On Ideas is a commentary on this (...) section of Alexander’s commentary on Aristotle. (shrink)

Zeno's extraordinary and disturbing paradoxes, the atomic theories of Democritus that so strikingly anticipate contemporary physics, the enigmatic and haunting epigrams of Heraclitus - these are just some of the riches to be found in this collection of writings of the early Greek philosophers. Jonathan Barnes's masterly Introduction shows how the most skilled detective work is often needed to reconstruct the ideas of these thinkers from the surviving fragments of their work. But the effort is always worth while. In forging (...) the first truly scientific vocabulary and offering rational arguments for their views, the pre-Socratics were doing something new and profoundly important; they also posed the questions that have remained at the centre of philosophy to this day.

Philosophical theories of gender are typically understood as theories of what it is to be a woman, a man, a nonbinary person, and so on. In this paper, I argue that this is a mistake. There’s good reason to suppose that our best philosophical theory of gender might not directly match up to or give the extensions of ordinary gender categories like ‘woman’.

Aristotle is one of the very greatest thinkers in the Western tradition, but also one of the most difficult. The contributors to this volume do not attempt to disguise the nature of that difficulty, but at the same time they offer a clear exposition of the central philosophical concerns in his work. Approaches and methods vary and the volume editor has not imposed any single interpretation, but has rather allowed legitimate differences of interpretation to stand. An introductory chapter provides an (...) account of Aristotle's life, and then guides the reader through the complex subject of what Aristotle actually wrote as a basis for characterising his philosophical development. Subsequent chapters cover Aristotle's writings on logic, metaphysics, science, psychology, ethics, politics, rhetoric, and poetics. It is a basic assumption of the Companion that its readers will not know Greek. (shrink)

Metaphysicians eager to engage with substantive, thoughtful, and provocative issues will be happy with John Heil’s From an Ontological Point of View. The book represents not only a sustained defence of a specific metaphysical theory, but also of a specific way of doing metaphysics. Put ontology first, Heil urges us, in order to remember that the original fascination of metaphysics wasn’t the question ‘what must the world be like in order to correspond neatly to our use of language?’, but rather (...) the altogether more fundamental ‘what must the world be like?’.
