The vital status of patients who are a part of controlled donation after circulatory death (cDCD) is widely debated in bioethical literature. Opponents to currently applied cDCD protocols argue that they violate the dead donor rule, while proponents of the protocols advocate compatibility. In this article, we argue that both parties often misinterpret the moral implications of the dead donor rule. The rule as such does not require an assessment of a donor’s vital status, we contend, but rather an assessment (...) of whether procurement of organs in cDCD cause the death of the donor or not. We then argue that commonly practiced cDCD protocols do not violate the dead donor rule, since the donation does not trigger or cause the death of the donors. (shrink)

The introduction of normothermic regional perfusion (NRP) in controlled donation after circulatory determination of death (cDCDD) protocols is by some regarded as controversial and ethically troublesome. One of the main concerns that opponents have about introducing NRP in cDCDD protocols is that reestablishing circulation will negate the determination of death by circulatory criteria, potentially resuscitating the donor. In this article, I argue that this is not the case. If we take a closer look at the concept of death underlying the (...) circulatory criterion for determination of death, we find that the purpose of the criterion is to show whether the organism as a whole has died. I argue that this purpose is fulfilled by the circulatory criterion in cDCDD protocols, and that applying NRP does not negate the determination of death or resuscitate the donor. (shrink)

Der Artikel untersucht den originären Beitrag Simon Kronbergs zur deutschen Literatur des Expressionismus. Der zu den „vergessenen und verkannten Autoren der expressionistischen Generation” (Lützeler) gehörende Kronberg ist bis heute kaum untersucht. Als Sohn jüdisch-galizischer Zuwanderer 1891 in Wien geboren, studiert er 1913 bei Emile Jacques-Dalcroze, dessen Licht- und Bewegungschoreographien ihn nachhaltig prägen. Weitere Stationen sind Düsseldorf bei dem Schauspieler-Paar Lindemann/dumont, München und Berlin. 1934 emigriert er nach Palästina, wo er 1947 stirbt. Seine Texte entwerfen eine Sprache, deren sinnstiftende Bilder (...) von seiner biographischen Erfahrung geprägt sind und jüdische Mystik, Tanz und Rhythmus auf spezifische Weise integrieren. Im Zentrum steht Kronbergs Konzeption des Schattens als einer Möglichkeit der Wandlung des Menschen in einer Welt der Rationalität und der Entkopplung des täglichen Lebens von Körper und Sinnlichkeit hin zu einer Erfahrung des Lichts. Am Beispiel seiner Erzählung “Chamlam” zeigt der Beitrag, dass seine Schattenfiguren in einem beachtenswerten Spannungsverhältnis zum Diskurs der Gespenster im Expressionismus stehen. (shrink)

We investigate the computational complexity of deciding whether a given inference rule is admissible for some modal and superintuitionistic logics. We state a broad condition under which the admissibility problem is coNEXP-hard. We also show that admissibility in several well-known systems (including GL, S4, and IPC) is in coNE, thus obtaining a sharp complexity estimate for admissibility in these systems.

We develop canonical rules capable of axiomatizing all systems of multiple-conclusion rules over K4 or IPC, by extension of the method of canonical formulas by Zakharyaschev [37]. We use the framework to give an alternative proof of the known analysis of admissible rules in basic transitive logics, which additionally yields the following dichotomy: any canonical rule is either admissible in the logic, or it is equivalent to an assumption-free rule. Other applications of canonical rules include a generalization of the Blok–Esakia (...) theorem and the theory of modal companions to systems of multiple-conclusion rules or (finitary structural global) consequence relations, and a characterization of splittings in the lattices of consequence relations over monomodal or superintuitionistic logics with the finite model property.

We study the notion of conservative translation between logics introduced by (Feitosa & D’Ottaviano2001). We show that classical propositional logic (CPC) is universal in the sense that every finitary consequence relation over a countable set of formulas can be conservatively translated into CPC. The translation is computable if the consequence relation is decidable. More generally, we show that one can take instead of CPC a broad class of logics (extensions of a certain fragment of full Lambek calculus FL) including most (...) nonclassical logics studied in the literature, hence in a sense, (almost) any two reasonable deductive systems can be conservatively translated into each other. We also provide some counterexamples, in particular the paraconsistent logic LP is not universal. (shrink)

We study the extension 123) of the theory S21 by instances of the dual weak pigeonhole principle for p-time functions, dWPHPx2x. We propose a natural framework for formalization of randomized algorithms in bounded arithmetic, and use it to provide a strengthening of Wilkie's witnessing theorem for S21+dWPHP. We construct a propositional proof system WF , which captures the Π1b-consequences of S21+dWPHP. We also show that WF p-simulates the Unstructured Extended Nullstellensatz proof system of Buss et al. 256). We prove that (...) dWPHP is equivalent to a statement asserting the existence of a family of Boolean functions with exponential circuit complexity. Building on this result, we formalize the Nisan–Wigderson construction in a conservative extension of S21+dWPHP. (shrink)

We develop approximate counting of sets definable by Boolean circuits in bounded arithmetic using the dual weak pigeonhole principle (dWPHP(PV)), as a generalization of results from [15]. We discuss applications to formalization of randomized complexity classes (such as BPP, APP, MA, AM) in PV₁ + dWPHP(PV).

The purpose of this paper is to clarify the relationship between various conditions implying essential undecidability: our main result is that there exists a theory T in which all partially recursive functions are representable, yet T does not interpret Robinson’s theory R. To this end, we borrow tools from model theory — specifically, we investigate model-theoretic properties of the model completion of the empty theory in a language with function symbols. We obtain a certain characterization of ∃∀ theories interpretable in (...) existential theories in the process. (shrink)

We investigate the substitution Frege () proof system and its relationship to extended Frege () in the context of modal and superintuitionistic propositional logics. We show that is p-equivalent to tree-like , and we develop a “normal form” for -proofs. We establish connections between for a logic L, and for certain bimodal expansions of L.We then turn attention to specific families of modal and si logics. We prove p-equivalence of and for all extensions of , all tabular logics, all logics (...) of finite depth and width, and typical examples of logics of finite width and infinite depth. In most cases, we actually show an equivalence with the usual system for classical logic with respect to a naturally defined translation.On the other hand, we establish exponential speed-up of over for all modal and si logics of infinite branching, extending recent lower bounds by P. Hrubeš. We develop a model-theoretical characterization of maximal logics of infinite branching to prove this result. (shrink)

The 'readability of the world', according to Blumenberg, means an ideal of understanding. However, the question is whether our knowledge of the world should be described as an act of reading or, more generally, in terms of language. Many theorists argue that the 'model of the text' is not an adequate paradigm for describing culture and human understanding. Language has a central function in human life, but there are many non-linguistic ways of expression and of communication. The paper deals with (...) the various motives, which underlie the generalization of the reading metaphor in cultural sciences. (shrink)

Excerpt from Rechtsphilosophie Fast samtliche Anhanger absoluter rechtsphilosophischer Wertprinzipien im neunzehnten Jahrhundert so z. B. Stahl, Trendelenburg, Lasson haben den Empirismus auf sich wirken lassen und eine Versohnung der Spekulation mit der positiven Rechtswissenschaft zum mindesten angestrebt. In neuester Zeit hat vor allem Stammler die Einordnung des Rechts in absolute Zweckzusammenhange mit der Ansicht zu vereinigen gewusst, dass die formale Gesetzmassigkeit oder gegenstandliche Richtig keit lediglich einen Massstab fur oder eine unbedingte Anforde rung an das Recht, ein Ziel fur den (...) Gesetzgeber, nicht aber eine ausserlich verbindliche Norm fur das Zusammenleben der Menschen bedeuten kann. So erfullt die kritische Wertspekulation die Forderung Bergbohms, Philosophie des positiven Rechts zu sein.

We show how to formalize approximate counting via hash functions in subsystems of bounded arithmetic, using variants of the weak pigeonhole principle. We discuss several applications, including a proof of the tournament principle, and an improvement on the known relationship of the collapse of the bounded arithmetic hierarchy to the collapse of the polynomial-time hierarchy.

Recently, there have been attempts at offering new justifications of the Rawlsian idea of public reason. Blain Neufeld has suggested that the ideal of political autonomy justifies public reason, while R.J. Leland and Han van Wietmarschen have sought to justify the idea by appealing to the value of political community. In this paper, I show that both proposals are vulnerable to a common problem. In realistic circumstances, they will often turn into reasons to oppose, rather than support, public reason. However, (...) this counterintuitive result can be avoided if we conceive of autonomy and community differently. (shrink)
