The rapid diffusion of artificial intelligence (AI) technologies in the defence domain raises challenges for the ethical governance of these systems. A recent shift from the what to the how of AI ethics sees a nascent body of literature published by defence organisations focussed on guidance to implement AI ethics principles. These efforts have neglected a crucial intermediate step between principles and guidance concerning the elicitation of ethical requirements for specifying the guidance. In this article, we outline the key normative (...) choices and corresponding tradeoffs that are involved in specifying guidance for the implementation of AI ethics principles in the defence domain. These correspond to: the AI lifecycle model used; the scope of stakeholder involvement; the accountability goals chosen; the choice of auditing requirements; and the choice of mechanisms for transparency and traceability. We provide initial recommendations for navigating these tradeoffs and highlight the importance of a pro-ethical institutional culture. (shrink)

This article provides a methodology for the interpretation of AI ethics principles to specify ethical criteria for the development and deployment of AI systems in high-risk domains. The methodology consists of a three-step process deployed by an independent, multi-stakeholder ethics board to: (1) identify the appropriate level of abstraction for modelling the AI lifecycle; (2) interpret prescribed principles to extract specific requirements to be met at each step of the AI lifecycle; and (3) define the criteria to inform purpose- and (...) context-specific balancing of the principles. The methodology presented in this article is designed to be agile, adaptable, and replicable, and when used as part of a pro-ethical institutional culture, will help to foster the ethical design, development, and deployment of AI systems. The application of the methodology is illustrated through reference to the UK Ministry of Defence AI ethics principles. (shrink)

The Eleatic Visitor speaks forcefully when he insists, ‘Necessarily, whenever there is speech, it is speech of something; it is impossible for it not to be of something’. For ‘if it were not of anything, it would not be speech at all; for we showed that it is impossible for there to be speech that is speech of nothing’. Presumably, at 263c10, when he claims to have ‘shown’ that it is impossible for speech to be of nothing, the Visitor is (...) referring back to the Parmenidean puzzles at Sophist 237ff. (shrink)

Spinoza’s limited words on the subject of art has led many to claim that his philosophy is incompatible and even hostile to a theory of art. Such a critique begins by confusing modern aesthetic standards with Spinoza’s actual words on art and its objects. Beginning with this confusion, this paper will argue that Spinoza’s philosophy naturalises the work of art and conceives of things such as paintings and temples through his theory of complex bodies.Turning to the two places that Spinoza (...) discuss art—IIIP2Schol and IVP45Schol—this paper will argue that Spinoza understood works of art to be particularly complex and hence powerful extended bodies with a use value relative to the striving of the human individual. Accordingly it will be argued that because Spinoza conceived works of art to be external bodies–artistic bodies–, we should therefore begin to study art and its objects through Spinoza’s relational theory of the individual.

Artificial intelligence (AI) assurance is an umbrella term describing many approaches—such as impact assessment, audit, and certification procedures—used to provide evidence that an AI system is legal, ethical, and technically robust. AI assurance approaches largely focus on two overlapping categories of harms: deployment harms that emerge at, or after, the point of use, and individual harms that directly impact a person as an individual. Current approaches generally overlook upstream collective and societal harms associated with the development of systems, such as (...) resource extraction and processing, exploitative labour practices and energy intensive model training. Thus, the scope of current AI assurance practice is insufficient for ensuring that AI is ethical in a holistic sense, i.e. in ways that are legally permissible, socially acceptable, economically viable and environmentally sustainable. This article addresses this shortcoming by arguing for a broader approach to AI assurance that is sensitive to the full scope of AI development and deployment harms. To do so, the article maps harms related to AI and highlights three examples of harmful practices that occur upstream in the AI supply chain and impact the environment, labour, and data exploitation. It then reviews assurance mechanisms used in adjacent industries to mitigate similar harms, evaluating their strengths, weaknesses, and how effectively they are being applied to AI. Finally, it provides recommendations as to how a broader approach to AI assurance can be implemented to mitigate harms more effectively across the whole AI supply chain. (shrink)

Environmental policies to promote environmentally sustainable economic activity have often concentrated on larger firms. However, increasing attention is being paid to the role of small- and medium-sized enterprises (SMEs) and entrepreneurial actors. In this paper, we examine how policy tools are being used to improve the environmental performance of SMEs and to redirect entrepreneurial energies in more environmentally benign directions. The empirical section adopts a case-based comparative method to examine four instances of policymaking, drawn from different countries and industry sectors. (...) The paper argues that while some interventions have proved effective in their own terms, better integrated approaches are required to address today's complex and deep-rooted sustainability challenges. The paper identifies several policy implications including the need to: clarify the purpose of any intervention, address potential interactions and trade-offs; select appropriate tools based on informed reviews of the options; remain sensitive to context-specific factors; and devise effective vehicles for the promotion and governance of entrepreneurial initiatives.

The development of ethical guidelines and regulations regarding human subjects research has focused upon protection of vulnerable populations by relying on a limited typology of vulnerabilities. This results in several challenges: First, Institutional Review Boards struggle to interpret and apply the regulations because they are often vague and inconsistent. Second, applying the regulations to subjects who fit within multiple categories of vulnerability can lead to contradictions and the rejection of research that would be permissible if only one category were applicable. (...) Finally, some potential subjects have social and other context-based vulnerabilities that are not described in the federal regulations... (shrink)

According to Aristotle, Plato's efforts at metaphysical explanation not only fail, they are nonsensical. In particular, Plato's appeals to Forms as metaphysically explanatory of the sensibles that participate in them is "empty talk" since "'participating' means nothing". I defend Plato against Aristotle's charge by identifying a particular, substantive model of metaphysical predication as the favored model of Plato's late ontology. The model posits two basic metaphysical predication relations: self-predication and participation. In order to understand the participation relation, it is important (...) first to understand how Plato's Forms are self-predicative paradigms. According to the favored model, Forms are self-predicative paradigms insofar as they are ideal, abstract encoders of structural essences. Sensibles participate in Forms by exemplifying the structures encoded in the Forms. Given plausible conditions on metaphysical explanation, Plato's appeals to abstract Forms as metaphysically explanatory of sensibles is a reasonable competitor for Aristotle's appeals to natural, substantial forms. At the very least, Plato's appeals to a participation relation are not empty. (shrink)

In recent decades, the term ‘ legitimacy ’ has featured heavily in debates about international law and international institutions. Yet the concept of legitimacy, mercurial as it is, has remained under-scrutinized, leading to confusion and misuse. Rather than advancing a particular conception of what may make international law legitimate, this article seeks to clarify and complicate how international lawyers understand and use legitimacy as a concept. To begin, the article distinguishes between legal, moral and social legitimacy. It highlights the different (...) ways in which these three approaches to legitimacy have been used in international law scholarship, while drawing attention to some of their more problematic tendencies. From there, it breaks the concept of legitimacy down into three major elements: its object, subject and basis. It argues that the tendency to blur these elements has led to much of the uncertainty and obfuscation in legitimacy debates. Finally, the article stresses the importance of distinguishing legitimacy from other grounds for compliance, including coercion, self-interest and habit. Ultimately, it argues that if treated with sufficient rigour, legitimacy provides a useful analytical concept for international lawyers. In doing so, it aims to encourage and facilitate the participation of international lawyers in broader inter-disciplinary debates about legitimacy. (shrink)

While the work of Benedict de Spinoza has been a source of inspiration and curiosity for a variety of literary and artistic figures,1 his grounding philosophical principles are often cited as a hindrance for a productive engagement with art and art theory. Certain commentators cite Spinoza's "naturalism" and "rationalism" as reasons for his philosophy's "hostility" to art and culture.2 But these criticisms only prevail if: one holds that works of art and literature ought to have an ontological ground other than (...) the natural, and if art and literature are given in opposition to reason and rationality. In contrast to such studies that focus on the... (shrink)

This is the first book to consider the increasing importance of Jean-Luc Nancy's work, which has influenced key thinkers such as Jacques Derrida. All his major works have been translated into English, yet until now little has been made available on his place in contemporary philosophy. By showing how he situates his work in a contemporary context - the collapse of communism, the Gulf War, and the former Yugoslavia - this outstanding collection reveals how Nancy's engagement with Hegel, Marx, Nietzsche, (...) Heidegger and Derrida makes him one of the key contemporary continental philosophers. Providing new perspectives on the issues of sense, art and community, these essays make it impossible to approach philosophy without reference to the work Jean-Luc Nancy. (shrink)

This study looked for evidence of biases in the allocation and disengagement of attention in dysphoric individuals. Participants studied images for a recognition memory test while their eye fixations were tracked and recorded. Four image types were presented (depression-related, anxiety-related, positive, neutral) in each of two study conditions. For the simultaneous study condition, four images (one of each type) were presented simultaneously for 10 seconds, and the number of fixations and the total fixation time to each image was measured, similar (...) to the procedure used by Eizenman et al. (2003) and Kellough, Beevers, Ellis, and Wells (2008). For the sequential study condition, four images (one of each type) were presented consecutively, each for 4 seconds; to measure disengagement of attention an endogenous cuing procedure was used (Posner, 1980). Dysphoric individuals spent significantly less time attending to positive images than non-dysphoric individuals, but there were no group differences in attention to depression-related images. There was also no evidence of a dysphoria-related bias in initial shifts of attention. With respect to the disengagement of attention, dysphoric individuals were slower to disengage their attention from depression-related images. The recognition memory data showed that dysphoric individuals had poorer memory for emotional images, but there was no evidence of a conventional mood-congruent memory bias. Differences in the attentional and memory biases observed in depressed and dysphoric individuals are discussed. (shrink)

Immunology researchers are beginning to explore the possibilities of reproducibility, reuse and secondary analyses of immunology data. Open-access datasets are being applied in the validation of the methods used in the original studies, leveraging studies for meta-analysis, or generating new hypotheses. To promote these goals, the ImmPort data repository was created for the broader research community to explore the wide spectrum of clinical and basic research data and associated findings. The ImmPort ecosystem consists of four components–Private Data, Shared Data, Data (...) Analysis, and Resources—for data archiving, dissemination, analyses, and reuse. To date, more than 300 studies have been made freely available through the ImmPort Shared Data portal , which allows research data to be repurposed to accelerate the translation of new insights into discoveries.

Abstract There is general agreement that the targeting of civilians in war is morally wrong. But sometimes starvation tactics are accepted as being a better option than direct military attacks. This article questions this view by arguing that starvation tactics affect civilians first and inflict long-term suffering. It argues that they are not just unless they can be limited to a small area where only military personnel will be affected. It looks at the provision for starvation tactics in the Geneva (...) Conventions, and at the argument of double effect. It then illustrates the argument with three case studies: the siege of Leningrad; the application of sanctions prior to and during the Gulf War in 1990?1991; and restrictions of food during the war in Bosnia.

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

This paper critically engages with Tom Shakespeare’s book Disability rights and wrongs. It concentrates on his attempt to demolish the social model of disability, as well as his sketch of an “alternative” approach to understanding “disability”. Shakespeare’s critique, it is argued, does British disability studies a “wrong” by presenting it as a meagre discipline that has not been able to engage with disability and impairment effects in an analytically sophisticated fashion. What was required was a measured presentation and evaluation of (...) the rich mix of theoretical and empirically based ideas to be found in the discipline, as the groundwork for forward thinking located within a social oppression paradigm. Shakespeare’s undermining of the discipline’s credibility in the eyes of outsiders and newcomers represents a diversionary missed opportunity by an influential writer and activist.Shakespeare’s book1 has certainly stirred up debate, and invited a flurry of angry reviews, in disability studies in the UK—the social science discipline that has been developing radical ideas about disability and disablism since the 1980s. Peopled by both disabled academics and like-minded non-disabled researchers and writers, the DS community recognises that Shakespeare’s book seeks to deliver a fatal wound to what he sees as its sacred cow: the British social model of disability.Shakespeare explains that what he calls the “strong” version of the social model of disability was formulated by Michael Oliver, a leading DS writer and disability activist, on the basis of the social and political ideas advanced in the 1970s by a group of disabled individuals fighting to free themselves from what they experienced as an oppressive care system that relegated and segregated people with serious impairments to residential institutions and to the category of the unemployable.2 3 In short, the social model asserts that “disability” is not caused ….

The proposed revisions to Part Three of the Ethical and Religious Directives (ERDs)—on the professional-patient relationship—call attention to a number of timely, culturally relevant issues that require an understanding of the dignity of the human person and the true health of body, mind, and spirit. Several key issues newly discussed in these proposed revisions include transgender policies, the question of referrals for unethical clinical interventions, and triage and limited-resource allocation protocols for crisis situations. This paper draws on the theological and (...) philosophical basis forunderstanding the professional-patient relationship, especially in light of the metaphor of Christ the physician, in order to consider how the ERDs effectively address these key issues and promote true healing in Catholic health care.

In Pro Murena, Cicero argues that Cato’s rigid philosophical comportment to politics reflects a mistaken understanding both of philosophy and of politics. By implication, he suggests that there is an approach to philosophy that is compatible with political leadership. Specifically, he argues that a thoroughgoing commitment to the philosophy of the Platonic Academy (i.e., Academic Philosophy) is entirely compatible with a thoroughgoing commitment to political leadership in the late Roman Republic. This essay looks at the most famous treatment of philosophical (...) leadership in the Platonic corpus, the philosopher ruler of the Republic, and asks to what extent Cicero’s depiction of politics and philosophy is consonant with that account.

RésuméLa philosophie de Spinoza est souvent célébrée pour son fort courant anti-normatif. Spinoza soutient, par exemple, que le bien et le mal n'indiquent rien de positif dans les choses, et que les affects sont toujours particuliers à la situation dans laquelle ils surviennent. Et pourtant, Spinoza soutient que la mélancolie est « toujours mauvaise » et la gaieté « toujours bonne », problématisant ainsi un principe métaphysique clé de son système. Prêtant attention à certaines sections de l’Éthique et du Traité (...) théologico-politique, cet article offre une lecture de ces deux affects problématiques, avant d’établir un lien entre Spinoza et des travaux récents sur la mélancolie aux débuts de l’époque moderne, qui la conceptualisent comme un « assemblage ».

Socrates expresses at least some interest in the knowledge of knowledge as an ability “to divide things and say that one is knowledge and the other is not knowledge”. If Hugh Benson’s characteristically lucid and careful book succeeds in its portrayal of Socrates as epistemologist, then the Charmides text is perhaps more optimistic than is often conceded. For unlike Gregory Vlastos’s Socrates, who was “no epistemologist, ” Benson’s promises “a philosophically complex, fundamentally coherent, and remarkably influential model of knowledge, ” (...) a model Socrates arrives at, at least in part, by means of a reflective epistemological perspective.

This study is based on the self-reporting by circus artists’ concerning their injuries. We refer to the theoretical framework of emersiology and argue that circus artists may be able to soothe their distress and pain by learning through their body. We will draw further on the comparison between our therapeutic approach and the techniques of self-care introduced by Michel Foucault in his History of Sexuality.

Anecdotal reports obtained from three individuals with prosopagnosia, all of whom have participated in an investigation, capture the essence of their impairment. This article focuses on the contrast between two prominent forms of prosopagnosia, one of which results from an acquired brain insult in an otherwise premorbidly normal individual and a second which appears to be lifelong and occurs in the absence of any obvious brain damage, at least as evident on conventional brain imaging. It reviews two central issues: the (...) first concerns the similarities and differences in the psychological representations of faces in acquired prosopagnosia and congenital prosopagnosia, and the second concerns the nature of the underlying neural representations of faces in these two populations. Some well-established overlapping behavioral characteristics are identified. (shrink)

The use of transcranial Electrical Stimulation in the modulation of cognitive brain functions to improve neuropsychiatric conditions has extensively increased over the decades. tES techniques have also raised new challenges associated with study design, stimulation protocol, functional specificity, and dose-response relationship. In this paper, we addressed challenges through the emerging methodology to investigate the dose-response relationship of High Definition-transcranial Direct Current Stimulation, identifying the role of negative valence in tinnitus perception. In light of the neurofunctional testable framework and tES application, (...) hypotheses were formulated to measure clinical and surrogate endpoints. We posited that conscious pairing adequately pleasant stimuli with tinnitus perception results in correction of the loudness misperception and would be reinforced by concurrent active HD-tDCS on the left Dorsolateral Prefrontal Cortex. The dose-response relationship between HD-tDCS specificity and the loudness perception is also modeled. We conducted a double-blind, randomized crossover pilot study with six recruited tinnitus patients. Accrued data was utilized to design a well-controlled adaptive seamless Bayesian dose-response study. The sample size and optimum interims were anticipated for adaptive decision-making about efficacy, safety, and single session dose parameters. Furthermore, preliminary pilot study results were sufficient to show a significant difference within the longitudinally detected self-report tinnitus loudness between before and under positive emotion induction. This study demonstrated a research methodology used to improve emotion regulation in tinnitus patients. In the projected method, positive emotion induction is essential for promoting functional targeting under HD-tDCS anatomical specificity to indicate the efficacy and facilitate the dose-finding process. The continuous updating of prior knowledge about efficacy and dose during the exploratory stage adapts the anticipated dose-response model. Consequently, the effective dose range to make superiority neuromodulation in correcting loudness misperception of tinnitus will be redefined. Highly effective dose adapts the study to a standard randomized trial and transforms it into the confirmatory stage in which active HD-tDCS protocol is compared with a sham trial. Establishing the HD-tDCS intervention protocols relying on this novel method provides reliable evidence for regulatory agencies to approve or reject the efficacy and safety. Furthermore, this paper supports a technical report for designing multimodality data-driven complementary investigations in emotion regulation, including EEG-driven neuro markers, Stroop-driven attention biases, and neuroimaging-driven brain network dynamics.

Introduction: Probationers, offenders with less serious and non-violent offences, and under statutory supervision, have low levels of self-esteem and physical health, and high level of family conflict, and poorer quality of family relationships. This study examined the effectiveness of the existing probation service and the additional use of a positive family holistic health intervention to enhance physical, psychological, and family well-being in probationers and relationships with probation officers.Methods: Probationers under the care of the Hong Kong Social Welfare Department were randomized (...) into a care-as-usual control group, a brief intervention group receiving two 1-h individual sessions [of a brief theory-based positive family holistic health intervention integrating Zero-time Exercise and positive psychology themes of “Praise and Gratitude” in the existing probation service], or a combined intervention group receiving BI and a 1-day group activity with family members. The outcomes were physical activity, fitness performance, self-esteem, happiness, anxiety and depression symptoms, life satisfaction, quality of life, family communication and well-being, and relationships with probation officers. Self-administered questionnaires and simple fitness tests were used at baseline, 1-month and 3-month follow-up. Linear mixed model analysis was used to compare difference in the changes of outcome variables among groups, adjusted of sex, age, and baseline values. Focus group interviews were conducted. Thematic content analysis was used.Results: 318 probationers were randomized into CAU, BI, or CI group. CAU showed enhanced physical activity, fitness performance and psychological health, and family communication with small effect sizes. BI and CI showed further improved physical activity, family communication and family well-being. Additionally, CI reported greater improvements in the relationships with probation officers than CAU with a small effect size. CI also reported greater increases in physical activity and family communication than BI with small to moderate effect sizes. Qualitative feedbacks corroborated the quantitative findings.Conclusion: Our trial provided the first evidence of the effectiveness of probation service and the additional use of an innovative, relatively low-cost, theory-based brief positive family holistic health intervention. This intervention may offer a new model for enhancing probation service.Trial Registration: The research protocol was registered at the National Institutes of Health. (shrink)

Can researchers, interested in novel ways to assess HIV seroprevalence among populations which are otherwise hidden, collect condoms that have been discarded on the ground in a public sex environment and test them for HIV? Researchers, who use other types of abandoned samples, such as discarded syringes, hair or saliva samples, or excess biological samples, confront similar issues.
