Perceptual learning involves an improvement in perceptual judgment with practice, which is often specific to stimulus or task factors. Perceptual learning has been shown on a range of visual tasks but very little research has explored chromatic perceptual learning. Here, we use two low level perceptual threshold tasks and a supra-threshold target detection task to assess chromatic perceptual learning and category effects. Experiment 1 investigates whether chromatic thresholds reduce as a result of training and at what level of analysis learning (...) effects occur. Experiment 2 explores the effect of category training on chromatic thresholds, whether training of this nature is category specific and whether it can induce categorical responding. Experiment 3 investigates the effect of category training on a higher level, lateralized target detection task, previously found to be sensitive to category effects. The findings indicate that performance on a perceptual threshold task improves following training but improvements do not transfer across retinal location or hue. Therefore, chromatic perceptual learning is category specific and can occur at relatively early stages of visual analysis. Additionally, category training does not induce category effects on a low level perceptual threshold task, as indicated by comparable discrimination thresholds at the newly learned hue boundary and adjacent test points. However, category training does induce category effects on a supra-threshold target detection task. Whilst chromatic perceptual learning is possible, learnt category effects appear to be a product of left hemisphere processing, and may require the input of higher level linguistic coding processes in order to manifest.

Ethical decision-making frameworks assist in identifying the issues at stake in a particular setting and thinking through, in a methodical manner, the ethical issues that require consideration as well as the values that need to be considered and promoted. Decisions made about the use, sharing, and re-use of big data are complex and laden with values. This paper sets out an Ethics Framework for Big Data in Health and Research developed by a working group convened by the Science, Health and (...) Policy-relevant Ethics in Singapore Initiative. It presents the aim and rationale for this framework supported by the underlying ethical concerns that relate to all health and research contexts. It also describes a set of substantive and procedural values that can be weighed up in addressing these concerns, and a step-by-step process for identifying, considering, and resolving the ethical issues arising from big data uses in health and research. This Framework is subsequently applied in the papers published in this Special Issue. These papers each address one of six domains where big data is currently employed: openness in big data and data repositories, precision medicine and big data, real-world data to generate evidence about healthcare interventions, AI-assisted decision-making in healthcare, public-private partnerships in healthcare and research, and cross-sectoral big data.

The COVID-19 pandemic has both exposed and created deep rifts in society. It has thrust us into deep ethical thinking to help justify the difficult decisions many will be called upon to make and to protect from decisions that lack ethical underpinnings. This paper aims to highlight ethical issues in six different areas of life highlighting the enormity of the task we are faced with globally. In the context of COVID-19, we consider health inequity, dilemmas in triage and allocation of (...) scarce resources, ethical issues associated with research, ethical considerations relating to tracing apps, and exit strategies such as immunity passports and COVID-19 vaccines. Finally, we consider environmental issues in light of COVID-19. The paper also offers some ethical reflection on these areas as many parts of the world contemplate the recovery phase. (shrink)

Precision medicine is an emerging approach to treatment and disease prevention that relies on linkages between very large datasets of health information that is shared amongst researchers and health professionals. While studies suggest broad support for sharing precision medicine data with researchers at publicly funded institutions, there is reluctance to share health information with private industry for research and development. As the private sector is likely to play an important role in generating public benefits from precision medicine initiatives, it is (...) important to understand what the concerns are and how they might be mitigated. This study reports outcomes of a deliberative method of citizen engagement in Singapore that asked whether sharing precision medicine data with private industry would be permissible, and if so, under what circumstances. Findings from this citizens’ jury suggest sharing with industry would be permissible under certain conditions that are set out in nine recommendations. Implications of the recommendations and their underlying assumptions for policy decision makers are discussed. This study aligns with prior international studies which found conditional acceptance for data sharing with private industry, a public benefit requirement, specific reluctance to share with insurance companies and an emphasis on accountability and transparency to demonstrate trustworthiness. However, our results differ from prior studies in that opt-in consent did not dominate the deliberations as jurors were able to set it aside as an assumed prerequisite for participation in a precision medicine programme.

Abstract:This article repositions Thomas Arnold as a major nineteenth-century historian through an analysis of his most important work, the History of Rome (1838–42). While scholars have focused primarily on Arnold's role as headmaster of Rugby School and Liberal Anglican theologian, I examine his historical contribution in the context of the Romantic movement. Building on the work of B. G. Niebuhr and Giambattista Vico, Arnold interpreted the contest between the patricians and plebeians at Rome as emblematic of a universal class struggle, (...) in which failure to find a compromise between the rich and the poor would inevitably lead to disaster.

The explosion of research interest in faces and face processing and the engagement of a wide range of disciplines is fueled by theoretical fascination combined with applied importance. This article describes some of the psychological research that has accompanied the recent rapid development or deployment of systems for showing, building, or manipulating faces for a variety of purposes. It illustrates the psychological issues that arise in a range of engineering, medical, and legal contexts and shows that technological development has not (...) always been matched by an appreciation of the psychological issues that need to be overcome to take full advantage of new systems. In some areas the advances raise new psychological issues. New technology has simply replicated old problems—e.g. that witnesses cannot recall individual face features; or that resemblance and identity are not the same thing. (shrink)

There is wide agreement that community engagement is important for many research types and settings, often including interaction with ‘representatives’ of communities. There is relatively little published experience of community engagement in international research settings, with available information focusing on Community Advisory Boards or Groups (CAB/CAGs), or variants of these, where CAB/G members often advise researchers on behalf of the communities they represent. In this paper we describe a network of community members (‘KEMRI Community Representatives’, or ‘KCRs’) linked to a (...) large multi-disciplinary research programme on the Kenyan Coast. Unlike many CAB/Gs, the intention with the KCR network has evolved to be for members to represent the geographical areas in which a diverse range of health studies are conducted through being typical of those communities. We draw on routine reports, self-administered questionnaires and interviews to: 1) document how typical KCR members are of the local communities in terms of basic characteristics, and 2) explore KCR's perceptions of their roles, and of the benefits and challenges of undertaking these roles. We conclude that this evolving network is a potentially valuable way of strengthening interactions between a research institution and a local geographic community, through contributing to meeting intrinsic ethical values such as showing respect, and instrumental values such as improving consent processes. However, there are numerous challenges involved. Other ways of interacting with members of local communities, including community leaders, and the most vulnerable groups least likely to be vocal in representative groups, have always been, and remain, essential.

In lieu of an abstract, here is a brief excerpt of the content:A Message from the EditorPiers H.G. Stephens, EditorIt is now six years since this journal’s founding editor Victoria Davion sadly succumbed to premature fatal illness and I took over her editorial duties under the most unfortunate of circumstances. I stated publicly then that Vicky’s vision for the character and purpose of the journal would remain unchanged under my watch, and in keeping with that pledge, I am now (...) pleased to announce a major expansion of our editorial board to further promote that vision.Over the past two decades, the size of our board had declined significantly as a result of retirements and mortality, and so a restoration of the previous scale of editorial support was significantly overdue. In doing this, I have sought to protect and expand our international and interdisciplinary coverage in a way that honors the focus that Vicky gave the journal from the beginning, giving space to voices from the wider communities of concern impacted by ecological destruction and incorporating a broad and inclusive but critically engaged approach to the philosophical issues involved. Our new board includes members from a wider range of nations and disciplines, which should help us expand the journal’s reach while both manifesting and remaining faithful to the original mission that our founding editor set for it. In the process, we are welcoming a combination of new rising stars and well-established respected figures in environmental thought, and aiming to expand our sphere of influence well beyond our main subscriber base in North America. Our hope is that our new scholarly supporters will enable the journal to grow in tackling the newer and ever more complex issues and problems raised by climate change, biodiversity loss, and other ongoing ecological crises, while at the same time still remaining true to the spirit with which Vicky founded it.Readers, please join me in welcoming our new board members, who are listed in the front matter of this issue. We thank them immensely for their service and hope that their efforts will enable and support increased success for Ethics and the Environment.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & The Environment 25th Anniversary Issue:Introduction from the EditorPiers H.G. StephensAt the time that Vicky Davion conceived of and launched Ethics and the Environment twenty-five years ago, environmental philosophy was still struggling for acceptance and respectability as a philosophical subdiscipline. For most of the period since 1979 just one journal, Environmental Ethics, had been the primary beacon of the field, and a second, the United Kingdom-based Environmental (...) Values, had only started up in 1992. Much of the surrounding professional atmosphere at the time was less than congenial, especially in relation to any attempt to engage in philosophical radicalism via environmental thought, with much institutional pressure pushing towards seeing all the concerns of our nascent field as questions to be shuffled off into a subsection of applied ethics. As someone who was beginning my doctoral studies in Britain around that time, I well recall the pressures and the struggle for respectability that was involved, and such conditions made the bar for success in launching a new journal that much higher. Vicky's actions in beginning the journal thus required not only imagination and creativity, but a significant amount of intellectual courage.This courage manifested itself most obviously in the new ground that Ethics and the Environment set out to break. Environmental Ethics had tended to take much of its inspiration from the American conservation and preservation movements as well as debates over intrinsic value, while Environmental Values took a perspective that bridged these concerns to predominantly British political and economic theory, Ethics and the Environment responded to the institutional challenges facing the new field by broadening the range of voices and critique that environmental [End Page 1] philosophy articulated. From the earliest stages, radical perspectives that were unrepresented or underrepresented in the other journals—especially ecofeminism, deep ecology, indigenous and non-Western thought—were central to the identity and mission of Ethics and the Environment, and gave it a distinctive place and appeal. It was a risky strategy to take in the mid 1990s, yet it proved to be not only the right thing to do, broadening the debate and adding new protagonists, but also a path to produce a highly successful journal over time.Ethics and the Environment is today one of the top journals in environmental philosophy, still growing in its subscriptions and influence, and a living tribute to the quality of Vicky Davion's vision. As editor, I am often astounded at the range, diversity, and quality of the manuscript submissions we receive from a global audience, and though I remain saddened at the circumstances under which I took over the editorship, I am proud and grateful to be in charge of such a publication, and holding fast as best I can to its founding vision as the journal nears its 25th anniversary. Within the field of environmental philosophy Ethics and the Environment is deeply associated with our department and with the University of Georgia, and I hope that it may continue to be so for many a long year yet.

In lieu of an abstract, here is a brief excerpt of the content:IntroductionPiers H.G. StephensThis special issue of Ethics and the Environment is dedicated to the philosophical contributions of our founding editor, Victoria Davion, who launched the journal in 1996 and edited it until shortly before her death in November 2017. Vicky was a pioneering figure in ecofeminist philosophy, as well as being both the first woman to become a full professor and the first to be chair of the (...) Philosophy Department here at the University of Georgia. Naturally we have endeavored to give her a suitable tribute in this issue, which we hope you will appreciate.In addition to these achievements, Vicky developed and practiced a pedagogy that consistently complemented her philosophical perspective, and in the issue's opening piece, Cecilia Herles reflects personally on the enduring legacy and influence of Vicky Davion's teaching work, and the rich heritage that has flowed out of it for her students, encouraging egalitarian dialogue, interdisciplinarity, and a practicality that extended beyond the University and into the wider community. It is surely appropriate to begin our special issue with such an appreciation of the ways that Vicky touched and lifted up so many lives.These reflections are built upon in Chaone Mallory's essay, which takes Davion's key essay "Is Ecofeminism Feminist?" as its touchstone, examining that essay's vital influence on scholarship and activism as well as its key role in defining contemporary ecofeminism itself. Drawing upon Davion's arguments, Mallory tracks a series of vital questions for the development of the field. She demonstrates how Davion's early critical insights have helped sort the wheat from the chaff in dealing with concerns such as spirituality, irrationality, essentialism, and sexism within environmentalism, concerns that made ecofeminism questionable in some feminists' eyes, and she concludes with a positive exposition as to why "all feminisms, whether named this or not, should in some sense, be eco."From here we move to Ronnie Hawkins' extensive and detailed application of Davion's work to the neurobiological, cultural, and axiological roots of our contemporary ecological situation, in which Hawkins invokes [End Page 1] and applies the insights of Davion's 2002 essay "Anthropocentrism, Artificial Intelligence, and Moral Network Theory: An Ecofeminist Perspective." Drawing upon Davion's inventive use of Val Plumwood's account of dualisms, Hawkins stresses Davion's pioneering work in avoiding the reason/nature dualistic fracture, and uses this work to critique the predominant current discourses of AI and neuroscience, in the process further expounding Davion's critiques of anthropocentrism and logocentrism. Cashing out the wider implications of Davion's perspective for our models of the mind, Hawkins connects these to Iain McGilchrist's recent work on the neuropsychology of perception and morality, arguing that this new account of the interaction of the two cerebral hemispheres and their role in generating an orientation to the world for cognition and valuing is consistent with Davion's insights, and can both help explain the environmental failings of modern Western culture and give support for non-instrumentalizing and nonanthropocentric alternatives.Finally, Trish Glazebrook and Emmanuela Opoku offer an extended ecofeminist examination of the roles, significance, dangers, and current status of environmental protectors in contemporary global environmental politics. In a paper dedicated to Davion that addresses many of her concerns with the interlocking character of forms of oppression, they systematically investigate and elucidate the importance of environmental protectors, the struggles that they engage in, the increasing threats of violence that they face, and their significance in the fight against climate change, ultimately arguing that the UN should extend explicit protection to land and environmental defenders under its human rights umbrella.We think these contributions are a fitting tribute to our founding editor, and offer you this special issue with the wish that her legacy will endure.

This paper presents a theoretical elaboration of the ethical framework of classical capitalism as formulated by Adam Smith in reaction to the dominant mercantilism of his day. It is seen that Smith's project was profoundly ethical and designed to emancipate the consumer from a producer and state dominated economy. Over time, however, the various dysfunctions of a capitalist economy — e.g., concentration of wealth, market power — became manifest and the utilitarian ethical basis of the system eroded. Contemporary capitalism, dominated (...) as it is by large corporations, entrenched political interests and persistent social pathologies, bears little resemblance to the system which Smith envisioned would serve the common man. Most critiques of capitalism are launched from a Marxian-based perspective. We find, however, that by illustrating the wide gap between the reality of contemporary capitalism and the model of amoral political economy developed by Smith, the father of capitalism proves to be the most trenchant critic of the current order.

The purpose of this study is to determine the relative frequency of course offerings on social issues and business ethics in American business schools. Specifically, a random sample of the curricula of 119 American business schools were analyzed in order to gauge the importance given to coursework on ethics and social issues. The findings indicated that the incidence of such courses was generally low in American business curricula, particularly at the graduate level. These findings are discussed in light of the (...) current concern for more responsible corporate behavior. (shrink)

This paper provides new elements for reconstructing Heinrich Hertz's conversion from an electrodynamic concept to a concept of field theory, a process that took place between September 1887 and February 1888. First of all, it is argued that, contrary to what one could deduce from Hertz's own presentation in his Untersuchungen (or Electric Waves), paper N∘ 5 was actually written after the first publication of papers N∘ 6 and N∘ 7; this fact is illuminated by Hertz's unpublished correspondence (Section 1). (...) Following this reordering, an approximative process of Hertz's conversion based only on his published papers is described (Section 2). Second, by complementing Hertz's published Erinnerungen (or Memoirs, Letters, Diaries) with his unpublished Versuchsprotokolle (Laboratory notes), a much finer description of this conversion process is discussed (Section 3). It is finally concluded that Hertz's idea of “air waves” belongs at the very end of this process, and was mainly attained through experimental hints found within Helmholtz's theoretical framework.

There is so much truth in the conception of the state as a natural organism and of man as a political animal, as commonly contrasted with the various theories of the state as an artificial formation based on contract, or implied contract, that Aristotle's proposition is rarely criticized from any other standpoint. When Aristotle said that man was a political animal, that is that political life was his nature, and consequently that the state, as the ultimate development of his nature, (...) was a natural institution, or, as we should say, an organism, he was, we may say with a good deal of certainty, speaking in the light of this contrast. But his theory must be judged on its own merits, and not on the demerits of that which he was attacking. We may grant that the state is natural; but we may nevertheless mean by “natural” something other than Aristotle means. And if our conception of Nature is different from his, it will follow that our agreement about the state is one of words only. (shrink)

Henri Bergson created a rich and detailed theory of consciousness beginning with the publication of Time and Free Will in 1889 and continuing through the publication of The Two Sources of Morality and Religion in 1932. His theory had much in common with William James’s views in that both emphasized consciousness as a continuous process. James's famous ‘stream of consciousness’ is strikingly similar to Bergson's early notion of duration (duree), even if Bergson more strongly emphasized the temporal qualities of consciousness. (...) Bergson later modified his understanding of consciousness, creating a metaphysical vision that he hoped might not only overcome determinism and materialism, but also offer a sophisticated way to understand parapsychological phenomena such as telepathy and clairvoyance (topics of concern to many major theorists of the time). During his life, Bergson’s ideas were widely celebrated in the United States and in Europe. (shrink)

ExcerptIn 2021, in the pages of this journal, I contended that a coalition of interests in the United States had coalesced in opposition to the presidency of Donald Trump and duly taken power through the vehicle of Joe Biden.1 This coalition includes the Democratic Party, corporate elites, the media, academia, and—the subject of the present article—the national security (natsec) state. In that earlier piece, I focused on particular components of this coalition: legacy and social media. I went on in a (...) subsequent Telos piece to examine another of its elements: the academy.2 These fractions all appear, however, to be relatively minor players. While I argue that the legacy media have staged a counterrevolution to seize back control of the public sphere, this exhausts their parochial, pecuniary agenda; beyond this, they are simply part of a wider activist liberal cause. Contemporary liberal activism is in turn ideologically rooted in ideas propagated by sectors of the academy and hegemonic within it, but this has not, on my analysis, empowered the academy so much as the forces that make it increasingly redundant.

From the scene of the singing cicadas in the _Phaedrus_, we will show the affinities between the mention of the dangerous sleep at noon (_Phdr_. 258e6-259d8) and a mythical episode in the life of Epimenides. Next, we will look at the possible affinities between the description of Dionysian madness (_Phdr_. 244d5-245a1) and the type of divination practiced by Epimenides of Crete (DK 3 B 1-25). From these approaches, we intend to describe and elucidate the common imaginary with which Plato elaborates (...) his reception and assimilation of the archaic poetic tradition in his philosophy.

In the history of political thought, the relationship between property and power has been a central preoccupation. The very nature of private property, on many accounts, is to put owners in a position of self-serving power to make decisions about matters of concern to others. In many legal systems, the vast power of owners is pervasive, as an ever greater range of resources is brought within the property regime and subjected to private power backed by the coercive power of the (...) state. Political and legal philosophers have long puzzled over how to reconcile the nature of private property with the limits and social responsibilities upon which, at least for some accounts, property’s legitimacy depends. The perennial question, then, is how best to understand the nature of property such that property’s limits can also be accounted for coherently within our legal and constitutional arrangements. Robé’s book Property, Power and Politics provides us with a wide-ranging analysis of property. There is much that we agree with and applaud here. In this contribution we seek to situate a key aspect of his work within this larger context, and to offer a criticism of one element of his view: his rejection of an understanding of ownership as an office. In Robé’s analysis, offices belong in the public sphere, where officeholders are held to account by their constituencies. We argue that Robé’s rejection of the idea of ownership-as-office rests on a misunderstanding of the legal concept of “office.” Moreover, this idea, properly understood, provides sound conceptual support for the normative aims of Robé’s account: to bind property and social responsibility tightly together. Robé’s project to criticize the virtually unlimited power of private owners in the contemporary world is served, not undermined, by understanding property as an office. First, we provide a brief summary of the key elements of Robé’s view of property (Part II). We then introduce a theoretical perspective on property as office as it has been developed in legal theory (Part III). Finally, we argue that this perspective fits better with Robé’s stated purposes than his own rejection of it suggests and raises some questions for future discussion (Part IV). (shrink)

Despite the salient experience of encoding threatening events, these memories are prone to distortions and often non-veridical from encoding to recall. Further, threat has been shown to preferentially disrupt the binding of event details and enhance goal-relevant information. While extensive work has characterised distinctive features of emotional memory, research has not fully explored the influence threat has on temporal memory, a process putatively supported by the binding of event details into a temporal context. Two primary competing hypotheses have been proposed; (...) that threat can impair or enhance temporal memory. We analysed two datasets to assess temporal memory for an in-person haunted house experience. In study 1, we examined the temporal structure of memory by characterising memory contiguity in free recall as a function of individual levels of heart rate as a proxy of threat. In study 2, we replicated marginal findings of threat-related increases in memory contiguity found in study 1. We extended these findings by showing threat-related increases in recency discriminations, an explicit test of temporal memory. Together, these findings demonstrate that threat enhances temporal memory regarding free recall structure and during explicit memory judgments. (shrink)
