A global health archive consisting of podoconiosis tissue slides and blocks (which was collected and imported into the UK before the introduction of the Human Tissue Act), was donated to Brighton & Sussex Medical School in 2014. There is little guidance on the socioethical and legal issues surrounding the retrospective use of archived or ‘abandoned’ tissue samples, which poses a number of questions relating to the ethical standing of the archive. There is a great deal of interpretation in the guidelines (...) that are currently in existence; however, modern ethical principles cannot be applied as it is not feasible to either reconsent or retrospectively seek approval. Our research team believed that it was unethical to leave the archive in storage, as this option favours neither researcher nor subjects. Permission was obtained from the Human Tissue Authority and a local ethics board for the tissues to be utilized in on-going research on podoconiosis aetiology. There is a delicate balance between the benefits gained by society relating to the development and progress of scientific research and the risks to the donor regarding the reuse of their tissues. Clearer guidelines should be made available to ensure that researchers are able to reuse tissue archives in contemporary research. (shrink)

Emerging adult newlywed couples often experience many demands on their time, and three common problems may surface as couples try to balance these demands—problems related to finances, sleep, and sex. We used two waves of dyadic data from 1,001 emerging adult newlywed couples to identify four dyadic latent profiles from husbands’ and wives’ financial management behaviors, sexual satisfaction, and sleep quality: Flounderers, Financially Challenged Lovers, Drowsy Budgeters, and Flourishers. We then examined how husbands’ and wives’ marital satisfaction, in relation to (...) profile membership, varied at a later wave. We found that Financially Challenged Lovers and Flourishers had significantly higher marital satisfaction than Drowsy Budgeters and Flounderers. Whereas, Financially Challenged Lovers and Flourishers did not differ in terms of marital satisfaction, Drowsy Budgeters seemed to have slightly higher marital satisfaction than Flounderers for wives only. However, we did not find evidence that these connections meaningfully differed by sex. Implications for the efforts of clinicians and educators are discussed. (shrink)

Environmental Narratives in the Huainanzi and the Anthropocene analyzes the Anthropocene periodization using the Huainanzi, an eastern Eurasian text from the second century BCE. This book argues that the Anthropocene concept inhibits the transformative change needed to address global crises such as climate change and mass extinction.

On Anselmian theism, God is, amongst other things, a necessary being. On genuine modal realism, possible worlds are maximal mereological sums of spatiotemporally connected individuals. I argue in this paper that AT and GMR are either incompatible or their conjunction leads to—amongst other things—modal collapse. Specifically, I argue: regardless of whether God is concrete or abstract, His necessary existence either is inconsistent with AT-GMR or it leads to, amongst other things, modal collapse for AT-GMR. I conclude the paper by contending (...) that, if I am correct, the ATist will have an argument against the truth of GMR, and the GMRist will have an argument against the truth of AT. (shrink)

Lewisian theism is the view that both traditional theism and Lewis’s modal realism are true. On Lewisian theism, God must exist in worlds in one of the following ways: God can be said to have a counterpart in each world; God can be said to exist in each world in the way that a universal can be said to exist in worlds, i.e. through transworld identity; God can be said to be a scattered individual, with a part of God existing (...) in each world; and, God can be said to exist in each world, through His existing from the standpoint of each world. In the literature, – have been rejected as viable options. I grant that and are not viable. However, I believe that and have been too hastily rejected. Herein, I develop ways to respond to objections to and, and conclude that is a viable option for Lewisian theists. (shrink)

One can readily conceive of worlds of horrendous, gratuitous suffering. Moreover, such worlds seem possible. For classical theists, however, God, amongst other things, is perfectly good. So, the question arises: for classical theists are such evil worlds possible? Many classical theists have said no. This is the modal problem of evil. Herein, I discuss a related problem: the problem of evil worlds for Lewisian theism. Lewisian theism is the conjunction of Lewis’s modal realism and classical theism, and a leading Lewisian (...) theist, Almeida, thinks that Lewisian theists should admit the existence of on-balance evil worlds. I do not. Herein, I present a dilemma for Almeida: either give up God’s sovereignty and the reductionist account of modality or make God blameworthy for evil. (shrink)

Much of everyday language is vague, even in situations where vagueness could have been avoided. Yet the benefits of vagueness for hearers and readers are proving to be elusive. We discuss a range of earlier controlled experiments with human participants, and we report on a new series of experiments that we ourselves have conducted in recent years. These experiments, which focus on vague expressions that are part of referential noun phrases, aim to separate the utility of vagueness from the utility (...) of other factors that tend to co-occur with vagueness. After presenting the evidence, we argue that it supports a view where the benefits that vague terms exert are due to other influences, and not to vagueness itself. (shrink)

Sport Philosophy Now examines the current sports philosophy available and updates it in the “post-Lance Armstrong” age. While many sports philosophers have turned a blind eye to the reality of sport by focusing on ideologically-driven abstract ideals, this book offers an engaging alternative. Examining the field primarily through the competitive world of cycling, Matthew James McNees explores such issues as authenticity in sport, our tendency to create superficial high-minded meaning from the actions of athletes, and American capitalism in (...) sports.

Emily Paul has recently argued that Brian Leftow’s account of why the import of God’s becoming Incarnate is not temporal but modal fails. She argues that Leftow’s required modal variation is not satisfied. That is, we do not have the required variation across logical space concerning the Incarnation. Paul examines her argument on two possible worlds theories: theistic ersatzism and (what I call) Lewisian theism. She thinks that both possible worlds theories face difficulties. I argue that Paul fails to provide (...) a compelling argument against Leftow because, firstly, her defence of one her premises fails, and, secondly, she misjudges what is required for some of Leftow’s claims to be true. I also argue that some of the problematic consequences that Paul raises for theistic ersatzism and Lewisian theism either are not problematic or can be avoided. (shrink)

A selection of poems from a chapbook research creation regarding the mystery of the printing and distribution of the Treaty 6 parchment. Treaty 6 was signed in 1876 with the promise of parchment copies to be delivered to the signatories the following year. This delivery did not occur.

These poems are part of an ongoing research project examining the implications of (...) one-sided document access in a nation-to-nation agreement. (shrink)

This Open Access book shows how value sensitive design (VSD), responsible innovation, and comprehensive engineering can guide the rapid development of technological responses to the COVID-19 crisis. Responding to the ethical challenges of data-driven technologies and other tools requires thinking about values in the context of a pandemic as well as in a post-COVID world. Instilling values must be prioritized from the beginning, not only in the emergency response to the pandemic, but in how to proceed with new societal precedents (...) materializing, new norms of health surveillance, and new public health requirements. -/- The contributors with expertise in VSD bridge the gap between ethical acceptability and social acceptance. By addressing ethical acceptability and societal acceptance together, VSD guides COVID-technologies in a way that strengthens their ability to fight the virus, and outlines pathways for the resolution of moral dilemmas. This volume provides diachronic reflections on the crisis response to address long-term moral consequences in light of the post-pandemic future. Both contact-tracing apps and immunity passports must work in a multi-system environment, and will be required to succeed alongside institutions, incentive structures, regulatory bodies, and current legislation. This text appeals to students, researchers and importantly, professionals in the field. (shrink)

According to classical theism, God is simple. However, contemporary objections to divine simplicity abound. One of those objections has received a lot of attention recently: the contingency objection. The objection is taken to pose a threat to God's freedom. Tomaszewski argues that the argument that supports the contingency objection, however, is invalid. Herein, I supply two valid versions of the argument; thus, the classical theist is required to defuse the argument.

Yates has recently argued that modal dispositionalism invalidates the axiom. Both Yates and Allen have advanced responses to the objection: Yates’s response proposes installing truth into the possibility biconditional, and Allen’s response requires that all properties be construed as being essentially dispositional. I argue that supporters of Borghini and Williams’s modal dispositionalist theory cannot accept these responses, given critical tenets of their theory. But, since these responses to the objection are the most plausible in the literature, I conclude that the (...) threat that Borghini and Williams’s modal dispositionalist theory invalidates the axiom still looms large.

By comparing Object-Oriented Ontology (OOO) and Baudrillard through the lens of a study of the notion of withdrawal in Heidegger’s tool analysis and “The Question Concerning Technology”, this article explores the extent to which an Object-Oriented Baudrillard is possible, or even necessary. Considering an OOO understanding of Mauss’s gift-exchange, a possible critique of duomining in Baudrillard and a revision of Baudrillard’s understanding of art, the prospects of a new reading of Baudrillard and interpretation of OOO’s genealogy are established. These lines (...) of comparison qualify the role of withdrawal in Baudrillard and symbolic exchange for OOO, and lead towards the conclusion that an Object-Oriented Baudrillard is possible, but may not, conversely, be considered necessary.

Social media technologies are routinely identified as a strong and pervasive threat to digital well-being. Extended screen time sessions, chronic distractions via notifications, and fragmented workflows have all been blamed on how these technologies ruthlessly undermine our ability to exercise quintessential human faculties. One reason SMTs can do this is because they powerfully affect our emotions. Nevertheless, how social media technology affects our emotional life and how these emotions relate to our digital well-being remain unexplored. Remedying this is important because (...) ethical insights into and open the possibility of designing for social media technologies in ways that actively reinforce our digital well-being. In this article, we examine the way social media technologies facilitate online emotions because of emotional affordances. This has important implications for evaluating the ethical implications of today’s social media platforms, as well as for how we design future ones. (shrink)

The Society of American Foresters (SAF) has long had an ethic of using forests to benefit society. Now many foresters, prompted by Aldo Leopold and his land ethic, are wondering if SAF does not need a forest ethic, respecting the integrity of natural systems, to complement its ethic for society. Forests are communities as well as commodities. Forest management ought to expand from an ethical of multiple use to one of protecting multiple values found in forests.

Machine metaphors abound in life sciences: animals as automata, mitochondria as engines, brains as computers. Philosophers have criticized machine metaphors for implying that life functions mechanically, misleading research. This approach misses a crucial point in applying machine metaphors to biological phenomena: their reciprocity. Analogical modeling of machines and biological entities is not a one-way street where our understanding of biology must obey a mechanical conception of machines. While our understanding of biological phenomena undoubtedly has been shaped by machine metaphors, the (...) resulting insights have likewise altered our understanding of what machines are and what they can do.

In the mid-nineteenth century, the house sparrow ( Passer domesticus) was introduced to the United States, quickly spreading across the country. For a brief period in the late nineteenth and early twentieth centuries, the observation of sparrow behavior was something of an urban pastime. Traits such as intelligence, reason, persistence, and craftsmanship were conferred onto sparrows by American urbanites. This paper argues that sparrow intelligence was often conflated with domestication: the ability of the birds to adapt to living alongside humans. (...) Praise for the ingenuity of sparrows generally revolved around their nest building, particularly when such structures overcame the challenges posed by urban infrastructure and technology. Sparrows were far less praiseworthy when they caused electricity outages or contaminated water supplies. The sparrow in the United States demonstrates how the relationship between these anecdotes and their implications for animal minds was mediated by the technology and infrastructure of cities. Admirers of sparrows were not measuring the birds’ mental capacity, but rather their ability to adapt to human habitations. Sparrows were only granted intelligence once they had demonstrated their ability to become domesticated. (shrink)

It now seems technically feasible to culture human embryos beyond the “fourteen‐day limit,” which has the potential to increase scientific understanding of human development and perhaps improve infertility treatments. The fourteen‐day limit was adopted as a compromise but subsequently has been considered an ethical line. Does it remain relevant in light of technological advances permitting embryo maturation beyond it? Should it be changed and, if so, how and why? What justifications would be necessary to expand the limit, particularly given that (...) doing so would violate some people's moral commitments regarding human embryos? Robust stakeholder engagement preceded adoption of the fourteen‐day limit and should arguably be part of efforts to reassess it. Such engagement could also consider the need for enhanced oversight of human embryo research. In the meantime, developing and implementing reliable oversight systems should help foster high‐quality research and public confidence in it. (shrink)

Chemicals have penetrated everyday lives of men who have sex with men as never before, along with new online and mobile technologies used to seek pleasures and connections. Poststructuralist (including queer) explorations of these new intensities show how bodies exist in the form of (political) surfaces able to connect with other bodies and with other objects where they may find/create a function (e.g., reproduce or disrupt hegemonies). This federally funded netnographic study explored how a variety of chemicals such as recreational (...) drugs, pharmaceuticals and steroids are contributing to the construction of gay, bisexual and other men having sex with men (GBMSM) communities and their interactions with idealized masculinities in the age of increasing technology. Five major thematic categories emerged from our analysis: (1) assembling bodies and technologies, (2) becoming orgiastic, (3) experiencing stigma, (4) becoming machinic and (5) negotiating practices. Our analysis explores how and why GBMSM pursue excesses of pleasure and connection through the assemblages they make with sexualized drug use, online platforms and other men. (shrink)

Matthew Arnold was born at Laleham-on-Thames on 24 December 1822 as the eldest son of Dr Thomas Arnold and his wife Mary. He was educated at Winchester College, his father's old school; Rugby, where his father was headmaster; and Oxford. In 1851 he was appointed Inspector of Schools, pursuing this taxing career to support his wife and family until his retirement in 1886. He published his first volume of verse, The Strayed Reveller, and other Poems, in 1849 followed by (...) Empedocles on Etna, and other Poems (1852) and five further collections which appeared, with a diminishing number of new poems in each, between 1853 and 1867, after which his creative gift appeared to dwindle still further and he published little poetry. His career as a writer of prose began to take over after his election to the Professorship of Poetry at Oxford in 1857. Stimulated by preparing his lectures, many of the earliest published in 1865 as Essays in Criticism (First Series), he turned increasingly to the vigorous and widely ranging polemical commentaries on culture, religion, and society which were to make him known at home and abroad as the foremost critic of his day. He died suddenly of heart failure on 15 April 1888 while awaiting at Liverpool the arrival of his married daughter from America. (shrink)

Imagery is one of the new, exciting frontiers in cognitive therapy. From the outset of cognitive therapy, its founder Dr. Aaron T. Beck recognised the importance of imagery in the understanding and treatment of patient's problems. However, despite Beck's prescience, clinical research on imagery, and the integration of imagery interventions into clinical practice, developed slowly. It is only in the past 10 years that most writing and research on imagery in cognitive therapy has been conducted. The Oxford Guide to Imagery (...) in Cognitive Therapy is a landmark book, which will play an important role in the next phase of cognitive therapy's development. Clinicians and researchers are starting to recognise the centrality of imagery in the development, maintenance and treatment of psychological disorders - for example, in social phobia, agoraphobia, depression, PTSD, eating disorders, childhood trauma, and personality disorder. In the fields of cognitive psychology and cognitive neuroscience, researchers are identifying the key role that imagery plays in emotion, cognition and psychopathology.The Oxford Guide to Imagery in Cognitive Therapy has been written both for clinicians and researchers. For clinicians, it is a user-friendly, practical guide to imagery, which will enable therapists to understand imagery phenomenology, and to integrate imagery-based interventions into their cognitive therapy practice. For researchers, it provides a state-of-the-art summary of imagery research, and points the way to future studies. Written by three well-respected CBT researcher-clinicians, it is essential reading for all cognitive therapists, who have recognised the limitations of purely 'verbal' CBT techniques, and want to find new ways to work with clients with psychological disorders. Readership: CBT therapists. (shrink)

Psychiatry is rapidly adopting digital phenotyping and artificial intelligence/machine learning tools to study mental illness based on tracking participants’ locations, online activity, phone and text message usage, heart rate, sleep, physical activity, and more. Existing ethical frameworks for return of individual research results (IRRs) are inadequate to guide researchers for when, if, and how to return this unprecedented number of potentially sensitive results about each participant’s real-world behavior. To address this gap, we convened an interdisciplinary expert working group, supported by (...) a National Institute of Mental Health grant. Building on established guidelines and the emerging norm of returning results in participant-centered research, we present a novel framework specific to the ethical, legal, and social implications of returning IRRs in digital phenotyping research. Our framework offers researchers, clinicians, and Institutional Review Boards (IRBs) urgently needed guidance, and the principles developed here in the context of psychiatry will be readily adaptable to other therapeutic areas.

Ours is an age full of desires but impoverished in its understanding of where those desires lead—an age that claims mastery over the world but also claims to find the world as a whole absurd or unintelligible. In The Vision of the Soul, James Matthew Wilson seeks to conserve the great insights of the western tradition by giving us a new account of them responsive to modern discontents. The western— or Christian Platonist—tradition, he argues, tells us that man (...) is an intellectual animal, born to pursue the good, to know the true, and to contemplate all things in beauty. Wilson begins by reconceiving the intellectual conservatism born of Edmund Burke’s jeremiad against the French Revolution as an effort to preserve the West’s vision of man and the cosmos as ordered by and to beauty. After defining the achievement of that vision and its tradition, Wilson offers an extended study of the nature of beauty and the role of the fine arts in shaping a culture but above all in opening the human intellect to the perception of the form of reality. Through close studies of Theodor W. Adorno and Jacques Maritain, he recovers the classical vision of beauty as a revelation of truth and being. Finally, he revisits the ancient distinction between reason and story-telling, between mythos and logos, in order to rejoin the two. Story-telling is foundational to the forms of the fine arts, but it is no less foundational to human reason. Human life in turn constitutes a specific kind of form—a story form. The ancient conception of human life as a pilgrimage to beauty itself is one that we can fully embrace only if we see the essential correlation between reason and story and the essential convertibility of truth, goodness and beauty in beauty. By turns a study in fundamental ontology, aesthetics, and political philosophy, Wilson’s book invites its readers to a renewal of the West’s intellectual tradition. (shrink)

Since the work of Gödel and Cohen, which showed that Hilbert's First Problem was independent of the usual assumptions of mathematics, there have been a myriad of independence results in many areas of mathematics. These results have led to the systematic study of several combinatorial principles that have proven effective at settling many of the important independent statements. Among the most prominent of these are the principles diamond and square discovered by Jensen. Simultaneously, attempts have been made to find suitable (...) natural strengthenings of ZFC, primarily by Large Cardinal or Reflection Axioms. These two directions have tension between them in that Jensen's principles, which tend to suggest a rather rigid mathematical universe, are at odds with reflection properties. A third development was the discovery by Shelah of "PCF Theory", a generalization of cardinal arithmetic that is largely determined inside ZFC. In this paper we consider interactions between these three theories in the context of singular cardinals, focusing on the various implications between square and scales, and on consistency results between relatively strong forms of square and stationary set reflection.

The results of four experiments provide evidence for controlled processing in the absence of awareness. Participants identified the colour of a neutral distracter word. Each of four words was presented in one of the four colours 75% of the time or 50% of the time . Colour identification was faster when the words appeared in the colour they were most often presented in relative to when they appeared in another colour, even for participants who were subjectively unaware of any contingencies (...) between the words and the colours. An analysis of sequence effects showed that participants who were unaware of the relation between distracter words and colours nonetheless controlled the impact of the word on performance depending on the nature of the previous trial. A block analysis of contingency-unaware participants revealed that contingencies were learned rapidly in the first block of trials. Experiment 3 showed that the contingency effect does not depend on the level of awareness, thus ruling out explicit strategy accounts. Finally, Experiment 4 showed that the contingency effect results from behavioural control and not from semantic association or stimulus familiarity. These results thus provide evidence for implicit control. (shrink)

A growing literature testifies to the persistence of place as an incorrigible aspect of human experience, identity, and morality. Place is a common ground for thought and action, a community of experienced particulars that avoids solipsism and universalism.

Each of these essays offers a philosophy of place, and reminds us that such philosophies ultimately decide how we make, use, and (...) understand places, whether as accidents, instruments, or fields of care.

During the latter-half of the nineteenth century, the utility of the house sparrow to humankind was a contentious topic. In Britain, numerous actors from various backgrounds including natural history, acclimatisation, agriculture and economic ornithology converged on the bird, as contemporaries sought to calculate its economic cost and benefit to growers. Periodicals and newspapers provided an accessible and anonymous means of expression, through which the debate raged for over 50 years. By the end of the century, sparrows had been cast as (...) detrimental to agriculture. Yet consensus was not achieved through new scientific methods, instruments, or changes in practice. This study instead argues that the rise and fall of scientific disciplines and movements paved the way for consensus on “the sparrow question.” The decline of natural history and acclimatisation stifled a raging debate, while the rising science of economic ornithology sought to align itself with agricultural interests: the latter overwhelmingly hostile to sparrows.

At the same time that social justice concerns are on the rise on college campuses, empathy levels among US college students are falling. Social injustice resulting from organizational decisions and actions causes profound and unnecessary human suffering, and research to understand antecedents to these decisions and actions lacks attention.

This study explores the potential relationship between empathy and social justice, using a multifaceted operationalization of social justice, which includes management actions and social sympathies. Results broadly support the positive empathy and social justice relationship and suggest higher education interventions to develop empathy in college business students. (shrink)

This volume is devoted to a reappraisal of the philosophy of Paul Feyerabend. It has four aims. The first is to reassess his already well-known work from the 1960s and 1970s in light of contemporary developments in the history and philosophy of science. The second is to explore themes in his neglected later work, including recently published and previously unavailable writings. The third is to assess the contributions that Feyerabend can make to contemporary debate, on topics such as perspectivism, realism, (...) and political philosophy of science. The fourth and final aim is to reconsider Feyerabend's place within the history of philosophy of science in the light of new scholarship. (shrink)

International courts are an integral component of the international legal system. These courts have been proliferating over time and increasingly working to ensure state compliance with the rules of the international regulatory regimes they join. However, these courts face a fundamental challenge: while they can rule against governments in violation of the regime’s rules, they cannot enforce those decisions. Working from the first principle that the regulatory regime is designed to help resolve collective action problems among the signees, this Article (...) proposes a formal model of international court influence that helps to explain the extent and limits of international court influence on national government behavior.

Towards the end of the nineteenth century, British colonists in Jamaica became increasingly exasperated by the damage caused to their sugar plantations by rats. In 1872, a British planter attempted to solve this problem by introducing the small Indian mongoose (Urva auropunctata). The animals, however, turned on Jamaica's insectivorous birds and reptiles, leading to an explosion in the tick population. This paper situates the mongoose catastrophe as a closing chapter in the history of the nineteenth-century acclimatization movement. While foreign observers (...) saw the introduction of the mongoose as a cautionary tale, caricaturing British Jamaica as overrun by a plague of weasels and ticks, British colonists, administrators and naturalists – identifying a gradual decline of both populations – argued that the ‘balance of nature’ would eventually reassert itself. As this paper argues, through this dubious claim they were attempting to retrospectively rationalize or justify the introductions and their disastrous aftermath. This strategy enabled them to gloss over the lasting ecological damage caused by the mongoose, and allowed its adherents to continue their uncritical support of both the Jamaican plantation economy and animal introductions in the British Empire.

We start by studying the relationship between two invariants isolated by Shelah, the sets of good and approachable points. As part of our study of these invariants, we prove a form of “singular cardinal compactness” for Jensen's square principle. We then study the relationship between internally approachable and tight structures, which parallels to a certain extent the relationship between good and approachable points. In particular we characterise the tight structures in terms of PCF theory and use our characterisation to prove (...) some covering results for tight structures, along with some results on tightness and stationary reflection. Finally, we prove some absoluteness theorems in PCF theory, deduce a covering theorem, and apply that theorem to the study of precipitous ideals. (shrink)

We prove a number of consistency results complementary to the ZFC results from our paper [J. Cummings, M. Foreman, M. Magidor, Canonical structure in the universe of set theory: part one, Annals of Pure and Applied Logic 129 211–243]. We produce examples of non-tightly stationary mutually stationary sequences, sequences of cardinals on which every sequence of sets is mutually stationary, and mutually stationary sequences not concentrating on a fixed cofinality. We also give an alternative proof for the consistency of the (...) existence of stationarily many non-good points, show that diagonal Prikry forcing preserves certain stationary reflection properties, and study the relationship between some simultaneous reflection principles. Finally we show that the least cardinal where square fails can be the least inaccessible, and show that weak square is incompatible in a strong sense with generic supercompactness. (shrink)

Design based research has been acknowledged as a productive approach for advancing educational technology. Coincidentally, open source software has been found to be a good fit for implementing design based research.
