I do four things in responding to Patrick Toner’s incisive critique of my Aquinas and the Ship of Theseus (AST). First, I further motivate Aquinas’s position that Socrates exists in the post-mortem and ante-resurrection state by noting that Socrates’ situation is at least analogous to other states of affairs that would certainly count as atypical (although not impossible). Secondly, I offer a revised Thomistic account of artefact identity through time in light of Toner’s objections to Aquinas’srestrictive view. Unlike the restrictive (...) view, this revised account is compatible with common-sense intuitions. Thirdly, I show how my defense of Aquinas’s substance metaphysic in AST is useful for the purpose of constructing defeators for certain kinds of arguments for reductionism. Fourthly, I defend Aquinas’s views on the unity of substance against Toner’s suggestion that they are implausible on the grounds that they are in conflict with certain so-called “scientifically informed”common-sense beliefs.

In a recent paper, “Incompatiblism, Sin, and Free Will in Heaven,” Timothy Pawl and Kevin Timpe discuss and propose a novel solution to a problem posed for traditional Christian theism that they call the Problem of Heavenly Freedom. In short, Christian tradition contains what seems to be a contradiction, namely, the redeemed in heaven are free but nonetheless can’t sin. Pawl and Timpe’s solution to the Problem of Heavenly Freedom is particularly attractive for two reasons: it shows great respect for (...) the Christian tradition’s teaching on heaven, and it entails that the redeemed in heaven act with morally weighty libertarian free will. Nonetheless, I think their solution can be improved upon. By drawing on some of the teachings of the Catholic tradition on heaven, particularly those of St. Thomas Aquinas, I raise three objections to Pawl and Timpe’s solution and introduce a modified version of their solution. In doing so, I have attempted to make their “best” solution to the Problem of Heavenly Freedom even better. (shrink)

One important part of Aquinas’s theory of the nature of corruptible corporeal substances is his account of the individuation of such entities. In this paper, I examine an aspect of Aquinas’s account of individuation that has not received as much attention as some others, namely, how Aquinas applies his account of individuation specifically to cases involving non-living corporeal substances. I first offer an interpretation of a key passage in Aquinas’s corpus where he explains his theory of individuation. Second, I examine (...) a text where Aquinas applies his account of individuation to a case involving non-living substances. Finally, I raise a possible objection to what Aquinas says about the individuation of non-living substances and in answering the objection suggest that Aquinas holds the view that non-living substances enjoy a less perfect mode of individuality when compared to living substances.

Coming out of mission efforts focused on evangelism, the rising Business as Mission movement stakes a claim to effective holistic mission by focusing on profit, evangelism, and development. Research indicates, however, that the development aspect of this `triple bottom line' is significantly weak. If, in fact, Business as Mission efforts were to incorporate the social and political dimensions of development, there would be great potential for a partnership with grassroots organizations to bring about deep-reaching social transformation.

This chapter outlines the utility for employing case study methodologies to provide sufficient external validity upon which to craft policy relevant to maintaining healthy democratic politics. The broader theoretical context is an investigation into the conditions that might structurally condition democracies to fail via democratic means. Venezuela’s democratic decline serves as the basis for the heuristic case study, wherein the objective is to identify the failures of the Venezuelan case in a larger framework that addresses the complexity of institutional design (...) in democratic political systems states broadly. Cases are selected based upon the objective of the researcher, and similarly, the case study methodology chosen rests firmly on their research goals. Lastly, the chapter outlines the research design necessary for satisfying broader inquiry within the more modest approach to how heuristic case studies can be used to inform both theory and policy.

This paper looks at nine different ways of defining scientism in order to show that potential definitions of the term conform to a general pattern: a definition of scientism either is self-defeating or else cannot really count as a construal of scientism in the first place. Advocates for the experimental sciences would therefore be better off accepting a middle position—one might say a broadly Thomistic approach to science—between the extremes of scientism on the one hand and a religious fundamentalism that (...) ignores the important contributions of the experimental sciences on the other. Such a middle position recognizes both the intellectual significance and the inherent limitations of the scientific method employed within the experimental sciences. (shrink)

There are wide individual differences in the ability to detect a stimulus contingency embedded in a complex paradigm. The present study used a cognitive masking paradigm to better understand individual differences related to contingency learning. Participants were assessed on measures of electrodermal arousal and on working memory capacity before engaging in the contingency learning task. Contingency awareness was assessed both by trial-by-trial verbal reports obtained during the task and by a short post-task recognition questionnaire. Participants who became aware had fewer (...) non-specific skin conductance responses and tended to score higher on a digit span assessment. Skin conductance level was not significantly lower in the aware group than in the unaware group. These findings are consistent with studies showing that lower arousal and greater cognitive processing capacity facilitate conscious perception of a greater breadth of information within a scene or a task.

Background While prenatal surgery historically was performed exclusively for lethal conditions, today intrauterine surgery is also performed to decrease postnatal disabilities for non-lethal conditions. We sought to describe physicians' attitudes about prenatal surgery for lethal and non-lethal conditions and to elucidate characteristics associated with these attitudes. Methods Survey of 1200 paediatric surgeons, neonatologists and maternal–fetal medicine specialists. Results Of 1176 eligible physicians, 670 responded. In the setting of a lethal condition for which prenatal surgery would likely result in the child (...) surviving with a severe disability, most respondents either disagreed or strongly disagreed that they would recommend the surgery. Male physicians were twice as likely to recommend surgery for the lethal condition, as were physicians who believe that abortion is morally wrong. Older physicians were less likely to recommend surgery. For non-lethal conditions, most respondents agreed that they would recommend prenatal surgery, even if the surgery increases the risk of prematurity or fetal death. Compared with MFMs, surgeons were less likely to recommend such surgery, as were physicians not affiliated with a fetal centre, and physicians who were religious. Conclusion Physician’s attitudes about prenatal surgery relate to physicians’ beliefs about disability as well as demographic, cultural and religious characteristics. Given the variety of views, parents are likely to receive different recommendations from their doctors about the preferable treatment choice. (shrink)

The Monographs produced by the International Agency for Research on Cancer (IARC) apply rigorous procedures for the scientific review and evaluation of carcinogenic hazards by independent experts. The Preamble to the IARC Monographs, which outlines these procedures, was updated in 2019, following recommendations of a 2018 expert Advisory Group. This article presents the key features of the updated Preamble, a major milestone that will enable IARC to take advantage of recent scientific and procedural advances made during the 12 years since (...) the last Preamble amendments. The updated Preamble formalizes important developments already being pioneered in the Monographs Programme. These developments were taken forward in a clarified and strengthened process for identifying, reviewing, evaluating and integrating evidence to identify causes of human cancer. The advancements adopted include strengthening of systematic review methodologies; greater emphasis on mechanistic evidence, based on key characteristics of carcinogens; greater consideration of quality and informativeness in the critical evaluation of epidemiological studies, including their exposure assessment methods; improved harmonization of evaluation criteria for the different evidence streams; and a single-step process of integrating evidence on cancer in humans, cancer in experimental animals and mechanisms for reaching overall evaluations. In all, the updated Preamble underpins a stronger and more transparent method for the identification of carcinogenic hazards, the essential first step in cancer prevention. (shrink)

BackgroundThe ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines are widely endorsed but compliance is limited. We sought to determine whether journal-requested completion of an ARRIVE checklist improves full compliance with the guidelines.MethodsIn a randomised controlled trial, manuscripts reporting in vivo animal research submitted to PLOS ONE (March–June 2015) were randomly allocated to either requested completion of an ARRIVE checklist or current standard practice. Authors, academic editors, and peer reviewers were blinded to group allocation. Trained reviewers performed outcome adjudication (...) in duplicate by assessing manuscripts against an operationalised version of the ARRIVE guidelines that consists 108 items. Our primary outcome was the between-group differences in the proportion of manuscripts meeting all ARRIVE guideline checklist subitems.ResultsWe randomised 1689 manuscripts (control: n = 844, intervention: n = 845), of which 1269 were sent for peer review and 762 (control: n = 340; intervention: n = 332) accepted for publication. No manuscript in either group achieved full compliance with the ARRIVE checklist. Details of animal husbandry (ARRIVE subitem 9b) was the only subitem to show improvements in reporting, with the proportion of compliant manuscripts rising from 52.1 to 74.1% (X2 = 34.0, df = 1, p = 2.1 × 10−7) in the control and intervention groups, respectively.ConclusionsThese results suggest that altering the editorial process to include requests for a completed ARRIVE checklist is not enough to improve compliance with the ARRIVE guidelines. Other approaches, such as more stringent editorial policies or a targeted approach on key quality items, may promote improvements in reporting. (shrink)

BackgroundThe pursuit of a cure for HIV is a high priority for researchers, funding agencies, governments and people living with HIV (PLWH). To date, over 250 biomedical studies worldwide are or have been related to discovering a safe, effective, and scalable HIV cure, most of which are early translational research and experimental medicine. As HIV cure research increases, it is critical to identify and address the ethical challenges posed by this research.MethodsWe conducted a scoping review of the growing HIV cure (...) research ethics literature, focusing on articles published in English peer-reviewed journals from 2013 to 2021. We extracted and summarized key developments in the ethics of HIV cure research. Twelve community advocates actively engaged in HIV cure research provided input on this summary and suggested areas warranting further ethical inquiry and foresight via email exchange and video conferencing.DiscussionDespite substantial scholarship related to the ethics of HIV cure research, additional attention should focus on emerging issues in six categories of ethical issues: (1) social value (ongoing and emerging biomedical research and scalability considerations); (2) scientific validity (study design issues, such as the use of analytical treatment interruptions and placebos); (3) fair selection of participants (equity and justice considerations); (4) favorable benefit/risk balance (early phase research, benefit-risk balance, risk perception, psychological risks, and pediatric research); (5) informed consent (attention to language, decision-making, informed consent processes and scientific uncertainty); and (6) respect for enrolled participants and community (perspectives of people living with HIV and affected communities and representation).ConclusionHIV cure research ethics has an unfinished agenda. Scientific research and bioethics should work in tandem to advance ethical HIV cure research. Because the science of HIV cure research will continue to rapidly advance, ethical considerations of the major themes we identified will need to be revisited and refined over time. (shrink)

The objective list theory of well-being holds that a plurality of basic objective goods directly benefit people. These can include goods such as loving relationships, meaningful knowledge, autonomy, achievement, and pleasure. The objective list theory is pluralistic (it does not identify an underlying feature shared by these goods) and objective (the basic goods benefit people independently of their reactive attitudes toward them). In this paper, I discuss the structure of this theory and show how it is supported by people's considered (...) judgments. I then respond to three objections. First, I argue that there is no conceptual reason to favor a monistic theory of well-being over a pluralistic one (such as the objective list theory). Second, I argue that states of affairs can benefit people even though they hold no positive reactive attitudes toward them. And, third, I argue that objective list theorists can identify a fairly-determinate list of basic goods. (shrink)

Ectogestation involves the gestation of a fetus in an ex utero environment. The possibility of this technology raises a significant question for the abortion debate: Does a woman’s right to end her pregnancy entail that she has a right to the death of the fetus when ectogestation is possible? Some have argued that it does not Mathison & Davis. Others claim that, while a woman alone does not possess an individual right to the death of the fetus, the genetic parents (...) have a collective right to its death Räsänen. In this paper, I argue that the possibility of ectogestation will radically transform the problem of abortion. The argument that I defend purports to show that, even if it is not a person, there is no right to the death of a fetus that could be safely removed from a human womb and gestated in an artificial womb, because there are competent people who are willing to care for and raise the fetus as it grows into a person. Thus, given the possibility of ectogestation, the moral status of the fetus plays no substantial role in determining whether there is a right to its death. (shrink)

Issues of interest, identity and values intertwine in environmental conflicts, creating challenges that cannot generally be overcome using rationalities grounded in generalised argumentation and abstraction. To address the growing need to engage interests and identities along with plural values in the conservation of biodiversity and ecological systems, we introduce the concept of ‘appropriateness of actions’ and ground it in a relational understanding of environmental ethics. A determination of appropriateness for actions comes from combining outputs from value elicitation with those of (...) interest and identity negotiation in ways that are salient to specific people and their relationships to specific places. Drawing on the Blue Mountain Forest Partnership in the Pacific Northwest, we propose factors of success for supporting appropriate actions: 1) understanding context and identifying key stakeholders; 2) surfacing a diversity of interests and building system-level trust; 3) building empathy for different identities grounded in specific places; 4) eliciting diverse values and seeking to understand their links to worldviews and knowledge systems and; 5) seeking out appropriate actions.

What, if anything, directly detracts from well-being? Objective list theorists affirm basic goods such as knowledge, friendship, and achievement, but it is less clear what they should say about opposing bads. In this paper, I argue that false beliefs, unhealthy relationships, and failed projects are not basic bads and do not directly detract from well-being. They can have bad effects or elements, or block the realization of basic goods, but do not themselves carry negative weight with respect to well-being. This (...) is shown by comparing cases where these bads are present and absent, examining their relation to negative overall well-being, and considering the role of these bads in the pursuit of positive goods.

Summary: This essay rejects the widespread thesis that conceptually creative metaphors are unpara‐phrasable on grounds that it misconceives the nature and function of paraphrase. Encouraged by a deceptively parallel rejection of the positivist reducibility thesis by philosophers of science, defenders of the unparaphrasability thesis mistakenly equated paraphrase with literal translation and in so doing failed to appreciate paraphrase's critical role in the systematic exploitation of metaphor's creative potential. This essay attempts to recast the terms of the paraphrasability debate by separating (...) paraphrase from literal translation and defending paraphrase's essential epistemic role in theory development. Three arguments for the paraphrasability of creative metaphor are presented followed by a critique of the major arguments for their unparaphrasability as formulated by Black, Cohen and Ricoeur. Résumé: Cet essai rejette, parce qu'elle repose sur une incomprehension de la nature et de la fonction de la paraphrase, la thése répandue selon laquelle des métaphores conceptuellement créatives ne peuvent pas être paraphraseées. Encouragés par un rejet faussement paralléle, par les philosophes des sciences, de la réductibilité positiviste, les défenseurs de la non‐paraphrasabilité ont confondu paraphrase et traduction littérale et, ce faisant, n'ont pas tenu compte du rôle critique de la paraphrase dans l'exploitation systématique du potentiel créatif de la métaphore. Cet essai tente de reformuler les termes du débat sur la paraphrasabilité en distinguant la paraphrase de la traduction littérale et en défendant le rôle épistémologique essentiel de la paraphrase dans le développe‐ment des théories. Trois arguments sont présentés pour la paraphrasabilité de la métaphore créative; suit une critique des principaux arguments contre la paraphrasabilité tels qu'ils ont été formulés par Black, Cohen et Ricoeur. Zusammenfassung: Es wird die weitverbreitete Auffassung widerlegt, wonach begrifflich kreative Metaphern nicht paraphrasierbar sind, weil sie Natur und Funktion der Paraphrase missversteht. Durch den scheinbar parallelen Fall der Verwerfung der Reduktionsthese durch Wissenschaftstheoretiker getäuscht setzten die Vertreter der These der Unparaphrasierbarkeit die Paraphrase mit der wört‐lichen Übersetzung gleich und sind deshalb nicht in der Lage, die kritische Funktion der Paraphrase bei der systematischen Verwertung des schöpferischen Potentials der Metapher zu erfas‐sen. Es wird versucht, das Problem der Paraphrasierbarkeit neu zu formulieren, indem die Paraphrase von der wörtlichen Übersetzung unterschieden wird und indem die erkenntnistheorelisch wesentliche Rolle der Paraphrase bei der Entwicklung von Theorien hervorgehoben wird. Es wer‐den drei Argumente zugunsten der Paraphrasierbarkeit von schopferischen Metaphern vorgelegt und die wichtigsten Argumente von Black, Cohen und Ricoeur gegen die Paraphrasierbarkeit kri‐tisiert.

In the United States, food banks served an estimated 46 million people in 2015. A combination of government policy reforms and political economic trends contributed to the rising numbers of individuals relying on private food assistance in the US, the United Kingdom and other high-income countries. Although researchers frequently map urban food environments, this project is one of the first to map private food assistance and potential need at the census-tract scale. We utilize Geographic Information Systems, demographic data, and food (...) assistance locations to develop a rapid assessment tool that could support food banks, pantries, soup kitchens, and government agencies that seek to answer the question of whether people with the greatest need have food distribution sites in close proximity. We define access based on distance and then calculate potential food insecurity using either poverty rates or a food insecurity index. We apply these methods in a case study analysis of Santa Clara County, California. Our findings suggest that food assistance distribution locations match the areas of potential need in more than 80% of urban census tracts. However, there are several potentially underserved locations and populations that could benefit from new food assistance operations. The poverty and index-based approaches show significant spatial overlap in mapped areas of high food insecurity and low access. The poverty only approach produces a higher estimate of food insecurity rates, is easier to calculate, and draws attention to the need to address poverty as a root cause of hunger. (shrink)

Next SectionIn an online study conducted separately in the UK and the US, participants rated the acceptability and fairness of four interventions: two types of financial incentives and two types of medical interventions. These were stated to be equally effective in improving outcomes in five contexts: weight loss and smoking cessation programmes, and adherence in treatment programmes for drug addiction, serious mental illness and physiotherapy after surgery. Financial incentives were judged less acceptable and to be less fair than medical interventions (...) across all five contexts. Context moderated the relative preference between rewards and penalties: participants from both countries favoured rewards over penalties in weight loss and treatment for serious mental illness. Only among US participants was this relative preference moderated by perceived responsibility of the target group. Overall, participants supported funding more strongly for interventions when they judged members of the target group to be less responsible for their condition, and vice versa. These results reveal a striking similarity in negative attitudes towards the use of financial incentives, rewards as well as penalties, in improving outcomes across a range of contexts, in the UK and the USA. The basis for such negative attitudes awaits further study. (shrink)

Written by leading experts in the field, Stellar Spectral Classification is the only book to comprehensively discuss both the foundations and most up-to-date techniques of MK and other spectral classification systems. Definitive and encyclopedic, the book introduces the astrophysics of spectroscopy, reviews the entire field of stellar astronomy, and shows how the well-tested methods of spectral classification are a powerful discovery tool for graduate students and researchers working in astronomy and astrophysics. The book begins with a historical survey, followed by (...) chapters discussing the entire range of stellar phenomena, from brown dwarfs to supernovae. The authors account for advances in the field, including the addition of the L and T dwarf classes; the revision of the carbon star, Wolf-Rayet, and white dwarf classification schemes; and the application of neural nets to spectral classification. Copious figures illustrate the morphology of stellar spectra, and the book incorporates recent discoveries from earth-based and satellite data. Many examples of spectra are given in the red, ultraviolet, and infrared regions, as well as in the traditional blue-violet optical region, all of which are useful for researchers identifying stellar and galactic spectra. This essential reference includes a glossary, handy appendixes and tables, an index, and a Web-based resource of spectra. In addition to the authors, the contributors are Adam J. Burgasser, Margaret M. Hanson, J. Davy Kirkpatrick, and Nolan R. Walborn. (shrink)

Over the past 40 years, the sense of place concept has been well-established across a range of applications and settings; however, most theoretical developments have ‘privileged the slow’. Evidence suggests that place attachments and place meanings are slow to evolve, sometimes not matching material or social reality (lag effects), and also tending to inhibit change. Here we present some key blind spots in sense of place scholarship and then suggest how a reconsideration of sense of place as ‘fast’ and ‘slow’ (...) could fill them. By this, we mean how direct and immediate perception-action processes presented in affordance theory (resulting in immediately perceived place meanings) can complement slower forms of social construction presented in sense of place scholarship. Key blind spots are that sense of place scholarship: 1) rarely accounts for sensory or immediately perceived meanings; 2) pays little attention to how place meanings are the joint product of attributes of environmental features and the attributes of the individual; and; 3) assumes that the relationship between place attachment and behaviour is linear and not constituted in dynamic relations among mind, culture and environment.. We show how these blind spots can begin to be addressed by reviewing key insights from affordance theory, and through the presentation of applied examples. We discuss future empirical research directions in terms of: 1) how sense of place is both perceived and socially constructed; 2) whether perceived and socially constructed dimensions of place can relate to one another when perceived meanings become unsituated, and; 3) how place attachment may change over different stages of the life course based upon dynamic relationships between processes of perception-action and social construction. We conclude with insights into how processes of perception-action and social construction could be included in the design and management of urban landscapes. (shrink)
