This book assesses how Vatican II opened up the Catholic Church to encounter, dialogue, and engagement with other world religions. Opening with a contribution from the President of the Pontifical Council for Interreligious Dialogue, Cardinal Jean-Louis Tauran, it next explores the impact, relevance, and promise of the Declaration Nostra Aetate before turning to consider how Vatican II in general has influenced interfaith dialogue and the intellectual and comparative study of world religions in the postconciliar decades, as well as the contribution (...) of particular past and present thinkers to the formation of current interreligious and comparative theological methods. Additionally, chapters consider interreligious dialogue vis-à-vis theological anthropology in conciliar documents; openness to the spiritual practices of other faith traditions as a way of encouraging positive interreligious encounter; the role of lay and new ecclesial movements in interreligious dialogue; and the development of Monastic Interreligious Dialogue. Finally, it includes a range of perspectives on the fruits and future of Vatican’s II’s opening to particular faiths such as Judaism, Islam, Hinduism, and Buddhism. (shrink)

Let (L; f) be a finite simple Ockham algebra and let (X;g) be its dual space. We first prove that every connected component of X is either a singleton or a generalised crown (i.e. an ordered set that is connected, has length 1, and all vertices of which have the same degree). The representation of a generalised crown by a square (0,1)-matrix in which all line sums are equal is used throughout, and a complete description of X, including the number (...) of connected components and the degree of the vertices, is given. We then examine the converse problem of when a generalised crown can be made into a connected component of (X; g). We also determine the number of non-isomorphic finite simple Ockham algebras that belong properly to a given subvariety P 2n,0. Finally, we show that the number of fixed points of (L; f) is 0,1, or 2 according to the nature of X. (shrink)

A pO -algebra $${(L; f, \, ^{\star})}$$ is an algebra in which ( L ; f ) is an Ockham algebra, $${(L; \, ^{\star})}$$ is a p -algebra, and the unary operations f and $${^{\star}}$$ commute. Here we consider the endomorphism monoid of such an algebra. If $${(L; f, \, ^{\star})}$$ is a subdirectly irreducible pK 1,1 - algebra then every endomorphism $${\vartheta}$$ is a monomorphism or $${\vartheta^3 = \vartheta}$$ . When L is finite the endomorphism monoid of L is (...) regular, and we determine precisely when it is a Clifford monoid. (shrink)

The mechanism of stellar aberration was explained and formulated by Bradley in terms of the existence of a unique reference frame for light propagation. However, Einstein's denial of the existence of such a frame appears to undermine Bradley's interpretation of the phenomenon. It is suggested that the recent evidence for a cosmologically-based inertial reference frame provides a new physical basis for Bradley's explanation in a manner consistent with the requirements of special relativity. It is shown that a “delay” effect is (...) also involved in our observation of the direction of nearby sources, and that the aberration and delay effects exactly compensate for nearby sources comoving with a terrestrial observer.

Background Empirical studies of surrogate decision-making tend to assume that surrogates should make only a 'substituted judgement'—that is, judge what the patient would want if they were mentally competent. Objectives To explore what people want in a surrogate decision-maker whom they themselves select and to test the assumption that people want their chosen surrogate to make only a substituted judgement. Methods 30 undergraduate students were recruited. They were presented with a hypothetical scenario about their expected loss of mental capacity in (...) the future and asked to answer some questions about their choice of surrogate. These data were analysed qualitatively using thematic content analysis. Results Most respondents talked about choosing someone who was caring and competent in certain ways, giving interesting evidence for their judgements. Surprisingly few highlighted how well they thought their chosen surrogate knew their preferences and would be able to make a substituted judgement. Moreover, few specified that their chosen surrogate had similar attitudes and values to their own and so would make a similar decision to theirs in the circumstances presented. Some respondents also referred to the social role of their chosen surrogate or the social dynamics of their situation which influenced their choices, as well as to ideas of reciprocity and characteristics of honesty and loyalty. Conclusion In the event that they lose mental capacity, many people will not select a surrogate to decide about medical treatments on their behalf solely on the basis that they expect their surrogate to make a substituted judgement.

In a reflective and richly entertaining piece from 1979, Doug Hofstadter playfully imagined a conversation between ‘Achilles’ and an anthill (the eponymous ‘Aunt Hillary’), in which he famously explored many ideas and themes related to cognition and consciousness. For Hofstadter, the anthill is able to carry on a conversation because the ants that compose it play roughly the same role that neurons play in human languaging; unfortunately, Hofstadter’s work is notably short on detail suggesting how this magic might be achieved1. (...) Conversely in this paper - finally reifying Hofstadter’s imagination - we demonstrate how populations of simple ant-like creatures can be organised to solve complex problems; problems that involve the use of forward planning and strategy. Specifically we will demonstrate that populations of such creatures can be configured to play a strategically strong - though tactically weak - game of HeX (a complex strategic game).We subsequently demonstrate how tactical play can be improved by introducing a form of forward planning instantiated via multiple populations of agents; a technique that can be compared to the dynamics of interacting populations of social insects via the concept of meta-population. In this way although, pace Hofstadter, we do not establish that a meta-population of ants could actually hold a conversation with Achilles, we do successfully introduce Aunt Hillary to the complex, seductive charms of HeX.

Most academic papers on ethics in pandemics concentrate on the duties of healthcare professionals. This paper will consider non-professional healthcare workers: do they have a moral obligation to work during an influenza pandemic? If so, is this an obligation that outweighs others they might have, e.g., as parents, and should such an obligation be backed up by the coercive power of law? This paper considers whether non-professional healthcare workers—porters, domestic service workers, catering staff, clerks, IT support workers, etc.—have an obligation (...) to work during an influenza pandemic. It uses data collected as part of a study looking at the attitudes of healthcare workers to working during a pandemic to suggest the philosophical arguments explored. These include: being in a position to do good, the ethics of work, competing obligations to family members and in particular to children and the obligations of citizens in a state of national emergency. We also look at whether compulsory measures are justified to support a national health service during a health emergency. We conclude that even if they are, compulsion should not be restricted to non-professionals who happen to be working in the health service at the time. Rather, compulsion involving a larger pool of people with the relevant skills and abilities is more equitable. (shrink)

Increasingly, national governments across the globe are prioritizing investments in neuroscience. Currently, seven active or in-development national-level brain research initiatives exist, spanning four continents. Engaging with the underlying values and ethical concerns that drive brain research across cultural and continental divides is critical to future research. Culture influences what kinds of science are supported and where science can be conducted through ethical frameworks and evaluations of risk. Neuroscientists and philosophers alike have found themselves together encountering perennial questions; these questions are (...) engaged by the field of neuroethics, related to the nature of understanding the self and identity, the existence and meaning of free will, defining the role of reason in human behavior, and more. With this Perspective article, we aim to prioritize and advance to the foreground a list of neuroethics questions for neuroscientists operating in the context of these international brain initiatives.

The informed consent process presents challenges for psychological trauma research (e.g. Institutional Review Board [IRB] apprehension). While previous research documents researcher and IRB-member perspectives on these challenges, participant views remain absent. Thus, using a mixed-methods approach, we investigated participant views on consent guidelines in two convenience samples: crowdsourced (N = 268) and undergraduate (N = 265) participants. We also examined whether trauma-exposure influenced participant views. Overall, participants were satisfied with current guidelines, providing minor feedback and ethical reminders for researchers. Moreover, (...) participant views for consent were similar irrespective of trauma-exposure. Our study has implications for IRBs and psychological researchers. (shrink)

© 2014 Taylor Francis. The Centers for Disease Control and Prevention recommends routine human immunodeficiency virus testing of every client presenting for services in venues where HIV prevalence is high. Because older adults have particularly poor prognosis if they receive their diagnosis late in the course of HIV disease, any screening provided to younger adults in these venues should also be provided to older adults. We examined aging-related disparities in recent and ever HIV testing in a probability sample of at-risk (...) adults seeking services in needle exchange sites, sexually transmitted disease clinics, and Latino community clinics that provide HIV testing. Using multiple logistic regression with generalized estimating equations, we estimated associations between age category and each HIV testing outcome. Even after controlling for covariates such as recent injection drug use, older adults had 40% lower odds than younger adults did of having tested in the past 12 months or ever. Aging-related disparities in HIV testing exist among clients of these high HIV prevalence venues and may contribute to known aging-related disparities in late diagnosis of HIV infection and poor long-term prognosis.

The inaugural southwest medical debate, between Exeter and Plymouth medical schools and respective health services, was held on the 3rd December 2014. Plymouth proposed the motion “This house believes the NHS should be privatised?” In an increasingly political climate, the National Health Service has become a constant topic for discussion in the media. On this occasion, all those debating were involved in the medical profession with roles encompassing clinical medicine, education, ethics, economics and policy. By allowing those with knowledge of (...) the NHS to speak, we hoped to spark novel discussions based on evidence and experience. (shrink)

Warning research participants and patients about potential risks associated with participation/treatment is a fundamental part of consent. However, such risk warnings might cause negative expectations and subsequent nocebo effects (i.e., negative expectations cause negative outcomes) in participants. Because no existing review documents how past research has quantitatively examined nocebo effects – and negative expectations – arising from consent risk warnings, we conducted a pre-registered scoping review (N = 9). We identified several methodological issues across these studies, which in addition to (...) mixed findings, limit conclusions about whether risk warnings cause nocebo effects. (shrink)
