Persons infected with the Human Immunodeficiency Virus often experience intermittent life-threatening infections, a progressive decrease in cognitive abilities, and a loss of capacity to communicate their wishes to their family and medical care providers. Accordingly, AIDS patients are among those most likely to benefit from the increased availability of legally recognized forms of advance care planning. Although the three countries examined in this article differ greatly in the prevalence of HIV infection, the legal status of advance directives, and in the (...) attitudes toward their use, a collection of case studies is used to demonstrate that an ability to address the specific needs, values and goals of individual patients is promoted by the availability of a variety of options for implementing advance directives or health care proxies. The conclusion of the analysis is that the best option in a specific context will depend upon differences in individual values and medical objectives of the sort discussed in the case studies. Das mit der HIV-Infektion verbundene Krankheitsbild ist durch wechselnde lebensbedrohliche Infektionen und den fortschreitenden Verfall kognitiver Fähigkeiten gekennzeichnet. Es führt zudem häufig zum Verlust der Möglichkeit, Behandlungswünsche gegenüber Ärzten und Angehörigen zu äußern. Deshalb gehören besonders AIDS-Patienten zu denjenigen, die von rechtlich anerkannten vorsorglichen Patientenverfügungen profitieren werden.In diesem Artikel werden drei Länder betrachtet, die sich hinsichtlich der Häufigkeit des Auftretens der HIV-Infektion sowie des rechtlichen Status von und der Einstellung zu Patientenverfügungen erheblich unterscheiden. Fallstudien belegen allerdings, daß nicht allein die kulturellen und sozialen Bedingungen für die jeweils beste Form der Patientenverfügung ausschlaggebend sind. Voraussetzung für die Möglichkeit, den Bedingungen, Wert- und Zielvorstellungen des individuellen Patienten zu entsprechen, ist auf jeden Fall die Verfügbarkeit unterschiedlicher Formen von Patienten- und Betreuungsverfügungen. Auch innerhalb eines Kulturkreises müssen daher verschiedene Formen vorsorglicher Willensäußerungen des Patienten rechtlich anerkannt werden. Welche Art von Verfügung jeweils die beste Option darstellt, ist dabei abhängig von medizinischen Bedingungen und persönlichen Wertvorstellungen, wie sie in den Fallstudien diskutiert werden.

It is shown that both classical and intuitionistic propositional logics of an associative binary modality are undecidable. The proof is based on the deduction theorem for these logics.

It is shown that the expressive power of second-order propositional modal logic whose modalities are S4.2 or weaker is the same as that of second-order predicate logic.

Data are lacking with regard to participants' perspectives on return of genetic research results to relatives, including after the participant's death. This paper reports descriptive results from 3,630 survey respondents: 464 participants in a pancreatic cancer biobank, 1,439 family registry participants, and 1,727 healthy individuals. Our findings indicate that most participants would feel obligated to share their results with blood relatives while alive and would want results to be shared with relatives after their death.

_Fish, Justice, and Society_ is a novel scholarly work that goes in depth into the fishing industry, fish, and aquatic environments. This book delves past the façade of what may be known by the average fisherman, bringing to the surface new information about numerous species and aquatic habitats.

The purpose of this study is exposition on the themes of method and mysticism in the work of Simone Weil. Nearly a decade before the onset of her first mystical experience, Weil developed a method to be rigorously applied in daily philosophical reflection. She outlines this method in her dissertation on Descartes (1929-1930). I examine the question of how Weil applied method to philosophical reflection on her mystical experiences (onset 1938-1939). I analyze Weil’s mystical experiences as a type of transformative (...) experience in L. A. Paul’s strict sense of the term. On Paul’s view, an experience is transformative if it is both epistemically and personally transformative. An experience is epistemically transformative if the only way to know what it is like to have it is to have it yourself. An experience is personally transformative if it changes your point of view, including your core preferences (Paul, 2014). I present a thought experiment and textual evidence to motivate the claim that Weil’s mystical experiences meet Paul’s conditions for transformative experience. I then propose two epistemological facts that can be revealed by philosophical reflection on mystical experience. First, it is possible to read meaning erroneously in the appearances of things. Second, it is possible to come to hold to the certainty of a conviction for reasons that elude the intellect. My findings suggest that Weil’s late views on philosophy accommodate these two epistemological constraints, thereby demonstrating a possible connection between Weil’s mystical experiences and her mature views on the nature, scope, and proper method of philosophy. However, my preliminary findings also suggest that Weil’s early work on method may have anticipated these epistemological obstacles prior to the onset of her first mystical experience. Thus, further exposition of Weil’s method is needed to support or elucidate the claim (Rozelle-Stone and Davis, 2021) that Weil’s epistemology underwent significant changes because of her mystical experiences.

Gene editing techniques, such as CRISPR, are being heralded as powerful new tools for delivering agricultural products and foods with a variety of beneficial traits quickly, easily, and cheaply. Proponents are concerned, however, about whether the public will accept the new technology and that excessive regulatory oversight could limit the technology’s potential. In this paper, we draw on the sociotechnical imaginaries literature to examine how proponents are imagining the potential benefits and risks of gene editing technologies within agriculture. We derive (...) our data from a content analysis of public comments submitted to the Food and Drug Administration’s 2017 docket titled “Genome Editing in New Plant Varieties Used for Food.” Our sample frame consists of 26 comments representing 30 agriculture and biotech companies, organizations, and trade associations. Our findings reveal three key sociotechnical imaginaries, including that gene editing technologies in agriculture: are not GMO but instead equivalent to traditional plant breeding; have the potential to usher in a new Green Revolution; and could facilitate the democratization of agricultural biotechnologies. We argue that forming and projecting these collective interpretations of the potential of gene editing technologies for crops and foods plays an important role in efforts by proponents to influence regulatory oversight, modes of governance, and build public acceptance. This research contributes to calls by science and technology studies scholars to investigate emergent concerns and imaginaries for novel technoscientific advances to help inform upstream models of public engagement and governance decisions.

The perception of sensory effects generated by one’s own actions is typically attenuated compared to the same effects generated externally. However, it is unclear whether this specifically relates to self-generation. Recent studies showed that sensory attenuation mainly relies on action preparation, not actual action execution. Hence, an attenuation of sensory effects generated by another person might occur if these actions can be anticipated and thus be prepared for.Here, we compared the perceived loudness of sounds generated by one’s own actions and (...) actions of another person that either could or could not be anticipated. We found an attenuation of the perceived loudness for self- as compared to other-generated sounds. This difference was independent of whether the sound-eliciting actions of the other person could be anticipated or not. Thus, sensory attenuation seems to be specifically tied to self-generation instead of being a secondary effect of agent-independent preparation for an upcoming action. (shrink)

We motivate and formalize the idea of sameness by default: two objects are considered the same if they cannot be proved to be different. This idea turns out to be useful for a number of widely different applications, including natural language processing, reasoning with incomplete information, and even philosophical paradoxes. We consider two formalizations of this notion, both of which are based on Reiter’s Default Logic. The first formalization is a new relation of indistinguishability that is introduced by default. We (...) prove that the corresponding default theory has a unique extension, in which every two objects are indistinguishable if and only if their non-equality cannot be proved from the known facts. We show that the indistinguishability relation has some desirable properties: it is reflexive, symmetric, and, while not transitive, it has a transitive “flavor.” The second formalization is an extension (modification) of the ordinary language equality by a similar default: two objects are equal if and only if their non-equality cannot be proved from the known facts. It appears to be less elegant from a formal point of view. In particular, it gives rise to multiple extensions. However, this extended equality is better suited for most of the applications discussed in this paper. (shrink)

Given the crucial role of the mass media in influencing public discourse, this study examines the discourses around climate change within the Brazilian press, covering the time period of 2003–2013. Survey evidence has shown that Brazilians’ degree of concern about climate change is higher than almost anywhere else, with nine out of 10 Brazilians considering climate change a serious problem. The primary purpose of this study is to investigate how the press engendered Brazilians’ striking level of climate change concern, with (...) special attention to how the discourse developed over time. To this end, I undertake a corpus-assisted discourse analysis to examine the most dominant linguistic patterns in the discourse, presenting evidence on an unprecedented scale and with considerable depth. The corpus consists of 19,686 newspaper texts published by 12 Brazilian broadsheet papers. The results are interpreted in the light of available opinion polls on the public’s perception of climate change as well as Brazil’s national context and environmental governance. (shrink)

Entscheidungen verweisen in einem begrifflichen Sinne auf Gründe. Entscheidungssysteme bieten eine probabilistische Verlässlichkeit als Rechtfertigung von Empfehlungen an. Doch nicht für alle Situationen mögen Verlässlichkeitsgründe auch angemessene Gründe sein. Damit eröffnet sich die Idee, die Güte von Gründen von ihrer Angemessenheit zu unterscheiden. Der Aufsatz betrachtet an einem Beispiel, einem KI-Lügendetektor, die Frage, ob eine (zumindest aktuell nicht gegebene) hohe Verlässlichkeit den Einsatz rechtfertigen kann. Gleicht er nicht einem Richter, der anhand einer Statistik Urteile fällen würde?

This article turns to Hannah Arendt's Eichmann in Jerusalem in order to illustrate the difficulties involved in approaching the (formerly) metaphysical concept of evil as a secular phenomenon. It asks how the advocate of plurality, natality and forgiveness could also vouch for the death sentence of Eichmann based on a rhetoric of retribution and revenge. It then shows that Arendt's surprisingly consistent view of evil is based on a quasi-ontological understanding of the human condition that allowed her to negate Eichmann's (...) humanity. Rather than simply unmasking a metaphysical account in disguise, however, the article develops an alternative perspective that emerges from the conversation between Arendt and Jaspers. It argues that Jaspers's interpretation of Kant offers a way to defend the idea of secular evil and judge Eichmann on the basis of his thoughtlessness. (shrink)
