El artículo presenta algunos resultados del estudio de la participación de Karol Wojtyła, obispo auxiliar y, sucesivamente, arzobispo de Cracovia, en el Concilio Vaticano II, así como de la recepción del mismo durante su ministerio pastoral en la archidiócesis polaca y al servicio de la Iglesia universal antes de su elección como sucesor de Pedro. Es posible hablar del “estilo conciliar” de Wojtyła: lo que la Iglesia ha enseñado sobre la gloria de Dios en el Vaticano II y sobre el (...) modo en el que dicha gloria debe acontecer en la vida de los fieles de nuestro tiempo encuentra en Wojtyła una concreta e iluminadora expresión histórica.

In this paper we argue the need to reimagine research ethics frameworks to include notions of environmental sustainability. While there have long been calls for healthcareethics frameworks and decision-making to include aspects of sustainability, less attention has focused on howresearchethics frameworks could address this. To do this, we first describe the traditional approach to research ethics, which often relies on individualised notions of risk. We argue that we need to broaden this notion of individual risk to consider issues associated with (...) environmental sustainability. This is because research is associated with carbon emissions and other environmental impacts, both of which cause climate change health hazards. We introduce how bioethics frameworks have considered notions of environmental sustainability and draw on these to help develop a framework suitable for researchers. We provide a case study of data-driven health research to apply our framework. (shrink)

Multiple studies show that periodic reanalysis of genomic test results held by clinical laboratories delivers significant increases in overall diagnostic yield. However, while there is a widespread consensus that implementing routine reanalysis procedures is highly desirable, there is an equally widespread understanding that routine reanalysis of individual patient results is not presently feasible to perform for all patients. Instead, researchers, geneticists and ethicists are beginning to turn their attention to one part of reanalysis—reinterpretation of previously classified variants—as a means of (...) achieving similar ends to large-scale individual reanalysis but in a more sustainable manner. This has led some to ask whether the responsible implementation of genomics in healthcare requires that diagnostic laboratories routinely reinterpret their genomic variant classifications and reissue patient reports in the case of materially relevant changes. In this paper, we set out the nature and scope of any such obligation, and analyse some of the main ethical considerations pertaining to a putative duty to reinterpret. We discern and assess three potential outcomes of reinterpretation—upgrades, downgrades and regrades—in light of ongoing duties of care, systemic error risks and diagnostic equity. We argue against the existence of any general duty to reinterpret genomic variant classifications, yet we contend that a suitably restricted duty to reinterpret ought to be recognised, and that the responsible implementation of genomics into healthcare must take this into account.

The United States health care industry is the second largest in the world, expending an estimated 479 million metric tons (MMT) of carbon dioxide per year, nearly 8 percent of the country's total emissions. The importance of carbon reduction in health care is slowly being accepted. However, efforts to “green” health care are incomplete since they generally focus on buildings and structures. Yet hospital care and clinical service sectors contribute the most carbon dioxide within the U.S. health care industry, with (...) structures/equipment and pharmaceuticals ranking as the third and fourth highest emitters in the industry. Given the magnitude of health care carbon emissions—and the paucity of attention to the carbon of hospital care and clinical services—this essay identifies overuse of health care as a health threat with serious ethical implications, offers a data‐driven action plan for carbon reduction in health care, and provides practical suggestions for more sustainable health care delivery in the United States.

The use of genomic testing in pregnancy is increasing, giving rise to questions over how the information that is generated should be offered and returned in clinical practice. While these tests provide important information for prenatal decision-making, they can also generate information of uncertain significance. This paper critically examines three models for approaching the disclosure of variants of uncertain significance (VUS), which can arise from forms of genomic testing such as prenatal chromosomal microarray analysis (CMA). Contrary to prevailing arguments, we (...) argue that respect for reproductive autonomy does not justify adopting a model on which an offer to disclose VUS is a routine part of genetic counselling. Instead, we contend that a commitment both to solidarity between healthcare providers and pregnant women and to the acceptance of a novel principle of caution under normative uncertainty means that we should instead adopt a model of VUS disclosure that imposes a strong presumption against offering to disclose VUS. The upshot of this is that it should be standard practice to only offer to disclose VUS when this is requested by the woman undergoing CMA. We defend our position against claims that arise from an alleged right to such information and that a presumption against an offer will lead to inequity. (shrink)

The US healthcare industry emits an estimated 479 million tonnes of carbon dioxide each year; nearly 8% of the country’s total emissions. When assessed by sector, hospital care, clinical services, medical structures, and pharmaceuticals are the top emitters. For 15 years, research has been dedicated to the medical structures and equipment that contribute to carbon emissions. More recently, hospital care and clinical services have been examined. However, the carbon of pharmaceuticals is understudied. This article will focus on the carbon emissions (...) of pharmaceuticals since they are consistently calculated to be among the top contributors to healthcare carbon and assess the factors that contribute to pharmaceutical carbon emissions. Specifically, overprescription, pharmaceutical waste, antibiotic resistance, routine prescriptions, non-adherence, drug dependency, lifestyle prescriptions, and drugs given due to a lack of preventive healthcare will be identified. Prescribing practices have environmental ramifications. Carbon reduction, when focused on pharmaceuticals, can lead to cleaner, more sustainable healthcare. (shrink)

While some countries are moving toward legalization, euthanasia is still criticized on various fronts. Most importantly, it is considered a violation of the medical ethics principle of non-maleficence, because it actively seeks a patient’s death. But, medical ethicists should consider an ethical alternative to euthanasia. In this article, we defend cryocide as one such alternative. Under this procedure, with the consent of terminally-ill patients, their clinical death is induced, in order to prevent the further advance of their brain’s deterioration. Their (...) body is then cryogenically preserved, in the hope that in the future, there will be a technology to reanimate it. This prospect is ethically distinct from euthanasia if a different criterion of death is assumed. In the information-theoretic criterion of death, a person is not considered dead when brain and cardiopulmonary functions cease, but rather, when information constituting psychology and memory is lost.

Some philosophers of religion have argued that moral anti-theodicy begs the question. This paper evaluates the arguments from two such philosophers, writing a decade apart—Robert Mark Simpson, and Lauri Snellman. Simpson argues that any global argument against theodicy must allow for the possibility of there existing a plausible theodicy, and that anti-theodical arguments (the argument from insensitivity, the argument from detachment, and the argument from harmful consequences) all implicitly discount this possibility, thus ending up begging the question. Snellman argues that (...) moral anti-theodicies presuppose that some evils cannot be justified, which would presuppose that theodicy is false from the start, which in turn would beg the question against theodicy. The author of the paper argues that Simpson’s arguments rest on an erroneous assumption regarding the nature of anti-theodicy, and that one of Simpson’s arguments sets a problematic standard for argumentation that the author argues we should not accept. It is also argued that Snellman’s argument relies on an unsupported claim from Toby Betenson. Therefore, the author concludes that Simpson and Snellman have not managed to show that moral anti-theodicies beg the question. (shrink)

The carbon emissions of global health care activities make up 4–5% of total world emissions, placing it on par with the food sector. Carbon emissions are particularly relevant for health care because of climate change health hazards. Doctors and health care professionals must connect their health care delivery with carbon emissions and minimize resource use when possible as a part of their obligation to do no harm. Given that reducing carbon is a global ethical priority, the informed consent process in (...) health care delivery must change. I argue that the expanded role of bioethicists in this climate crisis is to promote and support “green informed consent:” the sharing of climate information with patients, offering options for lower-carbon health care, and accepting the patient’s right to decline treatments which are deemed too carbon intensive for their values.

Although stakeholder theory is widely accepted in environmental disclosure research, empirical evidence about the role of stakeholders in firms’ disclosure is still scarce. The authors address this issue for a setting of carbon disclosure. Our international sample comprises the Carbon Disclosure Project Global 500, S&P 500, and FTSE 350 reports from 2008 to 2011, resulting in a total of 1,120 firms with 3,631 firm-year observations. The authors apply Tobit regressions to analyze the relationship between carbon disclosure and the relevance of (...) the following stakeholder groups: government, general public, media, employees, and customers. Our results confirm that in addition to carbon performance, all stakeholders are associated with carbon disclosure. Only one stakeholder group acts as a moderator for the relationship between carbon performance and carbon disclosure. Furthermore, the authors find that carbon performance but not the affiliation to a carbon-intensive industry acts as a moderator between stakeholder relevance and carbon disclosure. (shrink)

Similarity is one of the most important relations humans perceive, arguably subserving category learning and categorization, generalization and discrimination, judgment and decision making, and other cognitive functions. Researchers have proposed a wide range of representations and metrics that could be at play in similarity judgment, yet have not comprehensively compared the power of these representations and metrics for predicting similarity within and across different semantic categories. We performed such a comparison by pairing nine prominent vector semantic representations with seven established (...) similarity metrics that could operate on these representations, as well as supervised methods for dimensional weighting in the similarity function. This approach yields a factorial model structure with 126 distinct representation‐metric pairs, which we tested on a novel dataset of similarity judgments between pairs of cohyponymic words in eight categories. We found that cosine similarity and Pearson correlation were the overall best performing unweighted similarity functions, and that word vectors derived from free association norms often outperformed word vectors derived from text (including those specialized for similarity). Importantly, models that used human similarity judgments to learn category‐specific weights on dimensions yielded substantially better predictions than all unweighted approaches across all types of similarity functions and representations, although dimension weights did not generalize well across semantic categories, suggesting strong category context effects in similarity judgment. We discuss implications of these results for cognitive modeling and natural language processing, as well as for theories of the representations and metrics involved in similarity. (shrink)

Approximately 47 percent of women ages fifteen to forty‐four are currently without children, and slightly more than 20 percent of white women in America will never bear children, the highest percentage in modern history. Many fertile women who are childless are voluntarily so. Although any competent person twenty‐one years or older is legally eligible for voluntary sterilization, many doctors refuse to sterilize childfree women. This essay explores various reasons a woman would want to continue in her childfree lifestyle, evaluates the (...) accessibility of sterilization for women who are childfree by examining the reported reasons for denial of sterilization—both from the woman's and the physician's perspective—and assesses the legal status of voluntary sterilization for nonparous women. The essay also urges physicians to follow recommended guidelines for counseling women who, regardless of parity, desire sterilization and to provide this contraception if, after careful consideration, there are no outstanding health or other reasons that the procedure should not be performed.

It is largely acknowledged that natural languages emerge not just from human brains but also from rich communities of interacting human brains (Senghas, ). Yet the precise role of such communities and such interaction in the emergence of core properties of language has largely gone uninvestigated in naturally emerging systems, leaving the few existing computational investigations of this issue at an artificial setting. Here, we take a step toward investigating the precise role of community structure in the emergence of linguistic (...) conventions with both naturalistic empirical data and computational modeling. We first show conventionalization of lexicons in two different classes of naturally emerging signed systems: (a) protolinguistic “homesigns” invented by linguistically isolated Deaf individuals, and (b) a natural sign language emerging in a recently formed rich Deaf community. We find that the latter conventionalized faster than the former. Second, we model conventionalization as a population of interacting individuals who adjust their probability of sign use in response to other individuals' actual sign use, following an independently motivated model of language learning (Yang, , ). Simulations suggest that a richer social network, like that of natural (signed) languages, conventionalizes faster than a sparser social network, like that of homesign systems. We discuss our behavioral and computational results in light of other work on language emergence, and other work of behavior on complex networks. (shrink)

‘Bioethics still has important work to do in helping to secure status equality for LGBT people’ writes Timothy F. Murphy in a recent Bioethics editorial. The focus of his piece, however, is much narrower than human rights, medical care for LGBT people, or ending the HIV/AIDS pandemic. Rather, he is primarily concerned with sexuality and gender identity, and the medical intersections thereof. It is the objective of this response to provide an alternate account of bioethics from a Queer perspective. I (...) will situate Queer bioethics within Queer studies, and offer three ‘lessons’ that bioethics can derive from this perspective. These are not definitive rules for Queer bioethics, since it is a field which fundamentally opposes categorizations, favoring pastiche over principles. These lessons are exploratory examples, which both complement and contradict LGBT bioethics. My latter two lessons – on environmental bioethics and disability – overlap with some of Murphy's concerns, as well as other conceptions of LGBT bioethics. However, the first lesson takes an antithetical stance to Murphy's primary focus by resisting all forms of heteroconformity and disavowing reproduction as consonant with Queer objectives and theory. The first lesson, which doubles as a primer in Queer theory, does heavy philosophical lifting for the remainder of the essay. This response to Timothy F. Murphy, whose work is certainly a legacy in bioethics, reveals the multiplicity of discourses in LGBT/Queer studies, many of which are advantageous – even essential – to other disciplines like bioethics.

In 2014, the United States health care industry produced an estimated 480 million metric tons of carbon dioxide ; nearly 8% of the country's total emissions. The importance of sustainability in health care — as a business reliant on fossil fuels for transportation, energy, and operational functioning — is slowly being recognized. These efforts to green health care are incomplete, since they only focus on health care structures. The therapeutic relationship is the essence of health care — not the buildings (...) that contain the practice. As such, this article will first postulate reasons for a lack of environmental sustainability in US health care. Second, the article will focus on current green health care initiatives in the United States in which patients and physicians participate. Third, the rationale for participation in green initiatives will be explained. Fourth, the article will propose that, based on the environmental values of patients and physicians, health care insurance plans and health care insurance companies can be targeted for green health care reform, thereby closing the loop of sustainable health care delivery.

Through the use of assisted reproductive technologies (ARTs), multiple children are born adding to worldwide carbon emissions. Evaluating the ethics of offering reproductive services against its overall harm to the environment makes unregulated ARTs unjustified, yet the ART business can move towards sustainability as a part of the larger green bioethics movement. By integrating ecological ethos into the ART industry, climate change can be mitigated and the conversation about consumption can become a broader public discourse. Although the impact of naturally (...) made children on the environment is undeniable, I will focus on the ART industry as an anthropogenic source of carbon emissions which lead to climate change. The ART industry is an often overlooked source of environmental degradation and decidedly different from natural reproduction as fertility centres provide a service for a fee and therefore can be subject to economic, policy and bioethical scrutiny. In this article, I will provide a brief background on the current state of human-driven climate change before suggesting two conservationist strategies that can be employed in the ART business. First, endorsing a carbon capping programme that limits the carbon emissions of ART businesses will be proposed. Second, I will recommend that policymakers eliminate funded ARTs for those who are not biologically infertile. I will conclude the article by urging policymakers and all those concerned with climate change to consider the effects of the reproductive technologies industry in light of climate change and move towards sustainability.

Michael Walzer’s article ‘Political action: the problem of dirty hands’ initiated a new wave of discussion over a persistent problem in moral philosophy: are there situations in which ethical rules must be relaxed so as to bring about a greater good? In this article, we consider whether this ‘dirty hands’ approach may be applied to our current climate crisis. One proposed solution to the problem of global warming is the administration of moral enhancements to the population. Assuming that the administration (...) of moral enhancements is a necessary condition in the prevention of a climate crisis, Parker Crutchfield argues that this procedure ought to be covert. This implies lying to the public, and such dishonesty amounts to immoral behavior. We conclude that despite the severity of global warming, there is no justification for a dirty hands approach. Lying to the public in order to save the planet would probably create bigger problems, and it would ultimately be very counterproductive in trying to save the planet. (shrink)

The carbon emissions of global healthcare activities make up 4%–5% of total world emissions, with the majority coming from industrialised countries. The solution to healthcare carbon reduction in these countries, ostensibly, would be preventive healthcare, which is less resource intensive than corrective healthcare in itself and, as a double benefit, reduces carbon by preventing diseases which may require higher healthcare carbon to treat. This leads to a paradox: preventive healthcare is designed to give humans longer, healthier lives. But, by extending (...) life spans, the carbon emissions of a person increase both over a lifetime and in the medical industry overall. At the same time, the need for higher carbon end-of-life care does not disappear, particularly in resource intensive countries. This article will first identify sources of healthcare carbon, focusing on the industrialised world, and explain various efforts towards healthcare carbon reduction, which include preventive healthcare. Second, it will develop the ‘paradox of prevention’—that preventive healthcare may save healthcare carbon by proximally reducing the need for medical treatments, but also, paradoxically, result in more healthcare carbon both in an individual’s life and in the medical industry. The third section will offer ethical principles for approaching the paradox of prevention. The conclusion will emphasise the need for institutional approaches to healthcare carbon reduction in the industrialised world, which will relieve some of the tensions of healthcare industry decarbonisation and individual healthcare carbon use.

Health care is ubiquitous in the industrialized world. Yet, every medical development, technique, and procedure impacts the environment. Green bioethics synthesizes environmental ethics and biomedical ethics, thus creating an interdisciplinary approach to sustainable health care. Notably, green bioethics addresses not the structure of environmental sustainability in health-care institutions but the sustainability of individual health-care offerings. It parallels traditional biomedical ethics by providing four principles for ethical guidance: distributive justice, resource conservation, simplicity, and ethical economics. Through these four principles, green bioethics (...) presents a coherent framework for evaluating the sustainability of medical developments, techniques, and procedures. The future of our world may very well depend on how effectively we halt ecological destruction and conserve our resources in all areas of life. The principles of green bioethics, outlined in this book, will advance sustainability in health care. (shrink)

The story of the body. Fay Bound Alberti takes the human body apart in order to put it back anew, telling the cultural history of our key organs and systems from the inside out, from blood to guts, brains to sex organs.

Rieke van der Graaf, Karin Jongsma, Martine de Vries, Suzanne van de Vathorst, and Ineke Bolt have done well to voice ethical concerns over the decision of the IAB to host the next WCB in Qatar. Conferences should be more sustainable. Yet, attention to the carbon impact of conferences—and, perhaps, any country that a person might travel to for business or pleasure—are only one small part of environmentally responsible citizenship, especially for those trained in ethics and committed to health. Both (...) bioethics as a discipline and bioethicists as individuals need to interrogate their environmental choices. To this end, some ecological choices are more obvious targets of ethical scrutiny—diet and travel—while others appear sacrosanct, like reproduction and even healthcare use. This underscores the importance of making sustainable and ethical organizational choices, such as where to hold a conference, without absolving environmental accountability in other ethical calculations. Many organizations in academic and clinical medicine need to make drastic alterations in their practices and policies to effectively mitigate carbon. While the burden is not only on bioethics alone, the expectation that it should be remains. (shrink)

In recent years, many disciplines have become interested in the scientific study of morality. However, a conceptual framework for this work is still lacking. In The Moral Background, Gabriel Abend develops just such a framework and uses it to investigate the history of business ethics in the United States from the 1850s to the 1930s. According to Abend, morality consists of three levels: moral and immoral behavior, or the behavioral level; moral understandings and norms, or the normative level; and (...) the moral background, which includes what moral concepts exist in a society, what moral methods can be used, what reasons can be given, and what objects can be morally evaluated at all. This background underlies the behavioral and normative levels; it supports, facilitates, and enables them. Through this perspective, Abend historically examines the work of numerous business ethicists and organizations--such as Protestant ministers, business associations, and business schools--and identifies two types of moral background. "Standards of Practice" is characterized by its scientific worldview, moral relativism, and emphasis on individuals' actions and decisions. The "Christian Merchant" type is characterized by its Christian worldview, moral objectivism, and conception of a person's life as a unity. The Moral Background offers both an original account of the history of business ethics and a novel framework for understanding and investigating morality in general. (shrink)

A semantics of pictorial representation should provide an account of how pictorial signs are associated with the contents they express. Unlike the familiar semantics of spoken languages, this problem has a distinctively spatial cast for depiction. Pictures themselves are two-dimensional artifacts, and their contents take the form of pictorial spaces, perspectival arrangements of objects and properties in three dimensions. A basic challenge is to explain how pictures are associated with the particular pictorial spaces they express. Inspiration here comes from recent (...) proposals that analyze depiction in terms of geometrical projection. In this essay, I will argue that, for a central class of pictures, the projection-based theory of depiction provides the best explanation for how pictures express pictorial spaces, while rival perceptual and resemblance theories fall short. Since the composition of pictorial space is itself the basis for all other aspects of pictorial content, the proposal provides a natural foundation for further pictorial semantics. (shrink)

Low Power Society is a new approach to social complexes. It is not about slow scale but fast, it is not about absence of power but intense power. It is a possible answer to the negative aspects of our present globalization. The archetype (C.G.

This chapter explores logical semantics, that is, the structural meaning of logical expressions like connectives, quantifiers, and modalities. It focuses on truth-theoretical semantics for formalized languages, a tradition emerging from Carnap's and Tarski's work in the first half of the last century that specifies the meaning of these expressions in terms of the truth-conditions of the sentences in which they occur. It considers Tarski-style definitions of the semantics of a given language in a stronger metalanguage, Tarski's impossibility results, and attempts (...) to overcome them in the post-Tarskian tradition.

Medicalization occurs when an aspect of embodied humanity is scrutinized by the medical industry, claimed as pathological, and subsumed under medical intervention. Numerous critiques of medicalization appear in academic literature, often put forth by bioethicists who use a variety of “lenses” to make their case. Feminist critiques of medicalization raise the concerns of the politically disenfranchised, thus seeking to protect women—particularly natal sex women—from medical exploitation. This article will focus on three feminist critiques of medicalization, which offer an alternative narrative (...) of sickness and health. I will first briefly describe the philosophical origins of medicalization. Then, I will present three feminist critiques of medicalization. Liberal feminism, trans feminism, and crip feminism tend to regard Western medicine with a hermeneutics of suspicion and draw out potential harms of medicalization of reproductive sexuality, gender, and disability, respectively. While neither these branches of feminism—nor their critiques—are homogenous, they provide much-needed commentaries on phallocentric medicine. I will conclude the paper by arguing for the continual need for feminist critiques of medicalization, using uterus transplantation as a relevant case study. (shrink)

Philosophers have suggested that, in order to understand the particular visual state we are in during picture perception, we should focus on experimental results from vision neuroscience—in particular, on the most rigorous account of the functioning of the visual system that we have from vision neuroscience, namely, the ‘Two Visual Systems Model’. According to the initial version of this model, our visual system can be dissociated, from an anatomo-functional point of view, into two streams: a ventral stream subserving visual recognition, (...) and a dorsal stream subserving the visual guidance of action. Following this model, philosophers have suggested that, since the two streams have different functions, they represent different properties of a picture. However, the original view proposed by the ‘Two Visual Systems Model’ about the presence of a strong anatomo-functional dissociation between the two streams has recently been questioned on both philosophical and experimental grounds. Indeed, the analysis of several new pieces of evidence seems to suggest that many visual representations in our visual system, related to different tasks, are the result of a deep functional interaction between the streams. In the light of the renewed status of the ‘Two Visual Systems Model’, also our best philosophical model of picture perception should be renewed, in order to take into account a view of the process of picture perception informed by the new evidence about such interaction. Despite this, no account fulfilling this role has been offered yet. The aim of the present paper is precisely to offer such an account. It does this by suggesting that the peculiar visual state we are in during picture perception is subserved by interstream interaction. This proposal allows us to rely on a rigorous philosophical account of picture perception that is, however, also based on the most recent results from neuroscience. Unless the explanation offered in this paper is endorsed, all the recent evidence from vision neuroscience will remain unexplained under our best empirically informed philosophical theory of picture perception.
