Bear bile has long been used in the Asian traditional pharmacopoeia. Bear farming first started in China ~30 years ago in terms of reducing the number of poached bears and ensuring the supply of bear bile. Approximately 13,000 bears are today captivated on Asia’s bear farms: their teeth are broken and the claws are also pulled out for the sake of human safety; the bears are imprisoned in squeeze cages for years; and a catheter is daily inserted into a bear’s (...) gall bladder or a tube is implanted inside its body in order to collect the dripped bile—captive bears moan in severe pain whenever the bile is extracted. When the bears cannot produce sufficient bile, they are often left to die of starvation. It must be impossible to justify the bile extraction from living bears because (1) medicinal/herbal alternatives are similar to bear bile; (2) there is no evidence to suggest that bear farming has any beneficial effects on wild bear populations; and (3) ethical problems lie not only in the painful bile extraction but also the whole lifecycle of captive bears. In conclusion, human welfare (health care) based on traditional medicine is upheld by sacrificing bear welfare. Since a trial calculation suggests that it is economically unfeasible to keep a proper balance between bear welfare and the traditional pharmacopeia, the cultivation of herbal alternatives seems to be a possible solution to phase out bear faming and maintain the practice of traditional medicine in Asia.

In this note we show that groups with definable generics in a separably closed valued field K of finite imperfection degree can be embedded into groups definable in the algebraic closure of K.

Recently, Edwards and Liaschenko questioned the validity of an argument put forward by Dr Søren Holm and Joseph Dunne concerning the impossibility of a theory of nursing. Taking into consideration the premises of the argument, I describe how Maritain's conception of philosophy allows for the possibility of a theory of nursing conceived as a philosophy of nursing art that is both practical and propositional in nature. As well, I identify how the philosophy of nursing art guides nursing art in developing (...) and applying other kinds of artistic practical nursing knowledge: artistic nursing rules and artistic prudential nursing judgements. Finally, the relationship of ethical knowledge to artistic practical nursing knowledge is set down. (shrink)

Recently, a concern has been raised about a particular kind of behaviour that is adversely affecting the quality of nursing theoretical discourse. With the behaviour being attributed to nurses’ tendency to think in binary terms, it has been proposed that nurses replace their binary way of thinking with thinking that is inclusive and expansive and is based on an epistemology of contradiction. While agreeing that the behaviour of concern is indeed unscholarly, I disagree that the culprit is the binary. In (...) this commentary, I argue that the culprit is sophistical argumentation involving a binary (real or not) and that, by not making room for legitimate binaries, we run the danger of ‘throwing out the baby with the bathwater’. Further, I argue that the proffered solution is illusory. Its epistemological basis prohibits the deliverance of that which is promised. (shrink)

This paper introduces sequent systems for Visser's two propositional logics: Basic Propositional Logic (BPL) and Formal Propositional Logic (FPL). It is shown through semantical completeness that the cut rule is admissible in each system. The relationships with Hilbert-style axiomatizations and with other sequent formulations are discussed. The cut-elimination theorems are also demonstrated by syntactical methods.

By formalizing Berry's paradox, Vopěnka, Chaitin, Boolos and others proved the incompleteness theorems without using the diagonal argument. In this paper, we shall examine these proofs closely and show their relationships. Firstly, we shall show that we can use the diagonal argument for proofs of the incompleteness theorems based on Berry's paradox. Then, we shall show that an extension of Boolos' proof can be considered as a special case of Chaitin's proof by defining a suitable Kolmogorov complexity. We shall show (...) also that Vopěnka's proof can be reformulated in arithmetic by using the arithmetized completeness theorem. (shrink)

We give a proof of Gödel's first incompleteness theorem based on Berry's paradox, and from it we also derive the second incompleteness theorem model-theoretically.

This study explored representations of self-injury in Japanese manga. A content analysis of fifteen slice-of-life manga published between 2000-2017 was conducted, focusing on forty scenes that depict eighteen characters engaging in self-injury. Most depictions of self-injury reflect a stereotypical perception of “self-injurer,” a young girl cutting herself to cope with negative emotion. Characters receive informal support from friends and partners, while parents are portrayed as unsupportive and even triggering. An emergent trend was observed among manga targeting male readers to label (...) self-injuring women as “menhera” - mentally vulnerable damsels in distress - inviting a fetishistic gaze on the self-injuring female bodies.

We consider a set-theoretic version of mereology based on the inclusion relation ⊆ and analyze how well it might serve as a foundation of mathematics. After establishing the non-definability of ∈ from ⊆, we identify the natural axioms for ⊆-based mereology, which constitute a finitely axiomatizable, complete, decidable theory. Ultimately, for these reasons, we conclude that this form of set-theoretic mereology cannot by itself serve as a foundation of mathematics. Meanwhile, augmented forms of set-theoretic mereology, such as that obtained by (...) adding the singleton operator, are foundationally robust. (shrink)

It is well known that Gödel’s incompleteness theorems hold for ∑1-definable theories containing Peano arithmetic. We generalize Gödel’s incompleteness theorems for arithmetically definable theories. First, we prove that every ∑n+1-definable ∑n-sound theory is incomplete. Secondly, we generalize and improve Jeroslow and Hájek’s results. That is, we prove that every consistent theory having ∏n+1set of theorems has a true but unprovable ∏nsentence. Lastly, we prove that no ∑n+1-definable ∑n-sound theory can prove its own ∑n-soundness. These three results are generalizations of Rosser’s (...) improvement of the first incompleteness theorem, Gödel’s first incompleteness theorem, and the second incompleteness theorem, respectively.

We shall prove the second incompleteness theorem via Kolmogorov complexity.

We present a version of Herbelin’s image-calculus in the call-by-name setting to study the precise correspondence between normalization and cut-elimination in classical logic. Our translation of λμ-terms into a set of terms in the calculus does not involve any administrative redexes, in particular η-expansion on μ-abstraction. The isomorphism preserves β,μ-reduction, which is simulated by a local-step cut-elimination procedure in the typed case, where the reduction system strictly follows the “ cut=redex” paradigm. We show that the underlying untyped calculus is confluent (...) and enjoys the PSN property for the isomorphic image of λμ-calculus, which in turn yields a confluent and strongly normalizing local-step cut-elimination procedure for classical logic.

We define a liar-type paradox as a consistent proposition in propositional modal logic which is obtained by attaching boxes to several subformulas of an inconsistent proposition in classical propositional logic, and show several famous paradoxes are liar-type. Then we show that we can generate a liar-type paradox from any inconsistent proposition in classical propositional logic and that undecidable sentences in arithmetic can be obtained from the existence of a liar-type paradox. We extend these results to predicate logic and discuss Yablo’s (...) Paradox in this framework. Furthermore, we define explicit and implicit self-reference in paradoxes in the incompleteness phenomena. (shrink)

To preserve postoperative brain function, it is important for neurosurgeons to fully understand the brain's structure, vasculature, and function. Intraoperative high-frequency electrical stimulation during awake craniotomy is the gold standard for mapping the function of the cortices and white matter; however, this method can only map the “focal” functions and cannot monitor large-scale cortical networks in real-time. Recently, an in vivo electrophysiological method using cortico-cortical evoked potentials induced by single-pulse electrical cortical stimulation has been developed in an extraoperative setting. By (...) using the CCEP connectivity pattern intraoperatively, mapping and real-time monitoring of the dorsal language pathway is available. This intraoperative CCEP method also allows for mapping of the frontal aslant tract, another language pathway, and detection of connectivity between the primary and supplementary motor areas in the frontal lobe network. Intraoperative CCEP mapping has also demonstrated connectivity between the frontal and temporal lobes, likely via the ventral language pathway. Establishing intraoperative electrophysiological monitoring is clinically useful for preserving brain function, even under general anesthesia. This CCEP technique demonstrates potential clinical applications for mapping and monitoring large-scale cortical networks. (shrink)

We introduce a dual-context style sequent calculus which is complete with respectto Kripke semantics where implication is interpreted as strict implication in the modal logic K. The cut-elimination theorem for this calculus is proved by a variant of Gentzen's method.

Na doença falciforme, o genótipo HbSS da anemia falciforme, considerado a forma mais grave, prevalente no continente africano, tem alta morbidade e mortalidade. Objetivo: identificar se a estrutura instalada na atenção às pessoas com anemia falciforme e seus familiares, contribui para a redução da mortalidade precoce em Angola. Material e Método: pesquisa exploratória descritiva, realizada em Luanda-Angola, no período entre agosto e dezembro de 2022. Foram aplicados questionários estruturados para 20 pessoas com doença falciforme e 15 familiares, todos com mais (...) de 21 anos. A metodologia utilizada foi bola de neve. Para análise e discussão dos dados, foi utilizado o referencial teórico de Donabedian, com ênfase no eixo estrutura. Resultados: diagnóstico feito por sinais e sintomas, idade do diagnóstico entre 1 e 5 anos. A crise de dor predominou entre eventos agudos. Conclusão: inexistência de estrutura instalada de saúde em Luanda que garantam no serviço público gratuito o acesso à medicamentos, transfusão de sangue, vacinas especiais e exames complementares. A transferência de tecnologias sociais da organização de sociedade civil brasileira para a de Luanda mostra ser adequada. (shrink)

We introduce a Gentzen style formulation of Basic Propositional Calculus(BPC), the logic that is interpreted in Kripke models similarly tointuitionistic logic except that the accessibility relation of eachmodel is not necessarily reflexive. The formulation is presented as adual-context style system, in which the left hand side of a sequent isdivided into two parts. Giving an interpretation of the sequents inKripke models, we show the soundness and completeness of the system withrespect to the class of Kripke models. The cut-elimination theorem isproved (...) in a syntactic way by modifying Gentzen's method. Thisdual-context style system exemplifies the effectiveness of dual-contextformulation in formalizing various non-classical logics. (shrink)

Since the beginning of Christianity, the understanding of Christ’s sonship has played an essential role in soteriology. According to the Church Fathers and to the medieval theologians, the human person can become a son of God by the grace of adoption through the sonship of Christ. However, the German Dominican, Meister Eckhart , uses the theological concept 'the Only-begotten Son', which stands for the divine sonship of Christ himself, to describe the human condition and demonstrates the equality between Christ and (...) the human person. This quite unusual understanding drew the attention of the Church authorities in his time, because it could be associated with the doctrines of heretics in the late Middle Ages who insisted on the perfect identity between Christ and the human person. In the end, Eckhart’s teaching including the understanding of the sonship was condemned by the papal bull In agro dominico together with his other teachings. The present article attempts to reconstruct this one of the most challenging teachings of Eckhart by the analysis of his text, mainly the text of his German homilies, and to examine how he understands the relationship between Christ and the human person regarding the sonship.

On applique ici la méthode de l’analyse de réseau pour comprendre les temporalités de la construction de l’imprimerie, comme activité économique associant des hommes de lettres et des acteurs économiques. À partir des informations contenues dans l’Incunabula Short Title Catalogue, deux types de réseaux sont construits pour les éditions imprimées à Venise entre 1469 et 1500. Le premier permet d’observer le vivier des noms d’auteurs présents dans les éditions. Le second permet d’aller plus loin dans les notions de centralité et (...) d’autorité dans le réseau. Les presses vénitiennes se sont construites par l’utilisation réciproque des ateliers et des grands noms lettrés, dont le prestige légitimait les grandes entreprises typographiques. Avec le développement de l’imprimerie, les noms d’auteurs contemporains se font plus nombreux. Pour l’ensemble des lettrés impliqués dans l’imprimerie, cela se traduit par un rapport de force en leur défaveur. Les imprimeurs organisent eux-mêmes leurs collaborations en choisissant dans un vivier qui ne fait que s’accroître. Le prestige des auteurs est plus diffus et se nourrit de l’association de plusieurs noms dans une édition. Mais certains ont su particulièrement bien en jouer, comme le montre l’exemple d’Antonio Mancinelli. Ces réseaux éditoriaux, analysés dans leur épaisseur chronologique, permettent ainsi de redonner une vraie dimension temporelle à la construction d’une nouvelle industrie culturelle. (shrink)

We investigate two constants cT and rT, introduced by Chaitin and Raatikainen respectively, defined for each recursively axiomatizable consistent theory T and universal Turing machine used to determine Kolmogorov complexity. Raatikainen argued that cT does not represent the complexity of T and found that for two theories S and T, one can always find a universal Turing machine such that equation image. We prove the following are equivalent: equation image for some universal Turing machine, equation image for some universal Turing (...) machine, and T proves some Π1-sentence which S cannnot prove. © 2011 WILEY-VCH Verlag GmbH & Co.
