The introduction of contraceptive technologies hasresulted in the separation of sex and procreation. Theintroduction of new reproductive technologies (mainlyIVF and embryo transfer) has led not only to theseparation of procreation and sex, but also to there-definition of the terms mother and family.For the purpose of this essay, I will distinguishbetween:1. the genetic mother – the donor of the egg;2. the gestational mother – she who bears and gives birth to the baby;3. the social mother – the woman who raises the (...) child.This essay will deal only with the form of gestationalsurrogacy in which the genetic parents intend to bethe social parents, and the surrogate mother has nogenetic relationship to the child she bears anddelivers. I will raise questions regarding medicalethical aspects of surrogacy and the obligation(s) ofthe physician(s) to the parties involved. I will arguethat the gestational surrogate is a womb to rent,that there is great similarity between gestationalcommercial surrogacy and organ transplant marketing.Furthermore, despite claims to freedom of choice andfree marketing, I will claim that gestationalsurrogacy is a form of prostitution and slavery,exploitation of the poor and needy by those who arebetter off. The right to be a parent, although notconstitutional, is intuitive and deeply rooted.However, the issue remains whether this rightoverrules all other rights, and at what price to theparties involved. I will finally raise the followingprovocative question to society: In the interim periodbetween today''s limited technology and tomorrow''sextra-corporeal gestation technology (ectogenesis),should utilizing females in PVS (persistent vehetativestate) for gestational surrogacy be sociallyacceptable/permissible – provided they have leftpermission in writing?

AI systems have often been found to contain gender biases. As a result of these gender biases, AI routinely fails to adequately recognize the needs, rights, and accomplishments of women. In this article, we use Axel Honneth’s theory of recognition to argue that AI’s gender biases are not only an ethical problem because they can lead to discrimination, but also because they resemble forms of misrecognition that can hurt women’s self-development and self-worth. Furthermore, we argue that Honneth’s theory of recognition (...) offers a fruitful framework for improving our understanding of the psychological and normative implications of gender bias in modern technologies. Moreover, our Honnethian analysis of gender bias in AI shows that the goal of responsible AI requires us to address these issues not only through technical interventions, but also through a change in how we grant and deny recognition to each other.

This article offers a structural analysis of Cicero's Orator, sections 140–8. Situating Cicero's defence of a form of educational activity in relation to his earlier denials that he is teaching anything, the article proposes an explanation for Cicero's apparent reversal of position rooted in status theory, the conceptual framework developed by Greek and Roman rhetorical theorists for schematizing the points at issue in a case and the corresponding lines of approach that a defender should take. Understanding the status-inspired organization of (...) Cicero's self-defence affords readers smoother passage through a text that is often difficult and obscure. Furthermore, this analysis shows how Cicero deploys rhetorical techniques in defence of his educational endeavours both to support his claim to continued relevance and to exemplify the versatility of the ideal orator whom he portrays in the Orator.

The ethics of artificial intelligence is an upcoming field of research that deals with the ethical assessment of emerging AI applications and addresses the new kinds of moral questions that the advent of AI raises. The argument presented in this article is that, even though there exist different approaches and subfields within the ethics of AI, the field resembles a critical theory. Just like a critical theory, the ethics of AI aims to diagnose as well as change society and is (...) fundamentally concerned with human emancipation and empowerment. This is shown through a power analysis that defines the most commonly addressed ethical principles and topics within the field of AI ethics as either to do with relational power or with dispositional power. Moreover, it is concluded that recognizing AI ethics as a critical theory and borrowing insights from the tradition of critical theory can help the field forward. (shrink)

Visser's rules form a basis for the admissible rules of . Here we show that this result can be generalized to arbitrary intermediate logics: Visser's rules form a basis for the admissible rules of any intermediate logic for which they are admissible. This implies that if Visser's rules are derivable for then has no nonderivable admissible rules. We also provide a necessary and sufficient condition for the admissibility of Visser's rules. We apply these results to some specific intermediate logics and (...) obtain that Visser's rules form a basis for the admissible rules of, for example, De Morgan logic, and that Dummett's logic and the propositional Gödel logics do not have nonderivable admissible rules.

Este trabalho analisa a repercussão social do cartaz do “Salão do Livro da Região Sul e Sudeste do Pará”, evento da Feira Pan-Amazônica do Livro de 2018, para compreender como o processo de resposta social (BRAGA, 2006) impôs uma mudança institucional por parte da Secretaria de Cultura do Estado. O país homenageado foi a Colômbia e a peça de divulgação destacava uma mulher negra carregando livros na cabeça, representação das palenqueras. O fato gerou repercussão nas redes sociais e na mídia (...) local e nacional. Os protestos voltaram-se contra a reiteração de uma imagem que inferioriza as mulheres negras, reproduzindo colonialidades de gênero, poder e saber. O corpuscompõe-se de postagens no Facebooke de matérias jornalísticas veiculadas em abril de 2018. Duas técnicas metodológicas foram usadas: a netnografia (RECUERO, 2012; KOZINETS, 2014) e a aplicação de um questionário online, por meio do Facebook e Whatsapp. (shrink)

I graduated from law school in 1970 and I’ve been proud every day since of being a lawyer. My father was a lawyer, as are our two sons, and I’ve always seen lawyers as democracy’s warriors: the people who protect rights and by protecting rights protect justice. You law students are the future democracy warriors—actually, the future of democracy full stop—so this lecture is dedicated to you and to the hope that you will make justice your transcendent preoccupation, no matter (...) what you decide to do with your law degree. You are, after all, in law school where you have a window on what the law says—guided by your professors—and a window on what the law looks like outside the walls of your classrooms—guided by watching the news.

Rosalie Osmond examines both literal and metaphorical aspects of the relationship between body and soul in seventeenth-century literature and their significance within a primarily dualistic philosophy.

Ancient medical and healing systems are currently attracting considerable interest. This issue includes interdisciplinary studies which focus on new perceptions of some ancient and medieval medical systems, exploring how they related to each other, and assessing their contribution to modern society. It is shown that pre-Greek medicine included some rational elements, and that Egyptian and Babylonian medical systems contributed to a tradition which led from classical antiquity through the Middle Ages and beyond. The reliability of sources of evidence is considered, (...) as well as the legacy of the ancient healing environments and disease treatments. Finally, where documentation survives, the legacy of social attitudes to health and disease is considered. Overarching principles directed policies of social medicine and healthcare in antiquity and the Middle Ages: for example, the causes and transmission routes of infectious diseases, as well as the basic principles of sterilization, were unknown, but nevertheless attempts were made to improve sanitation, provide clean water, and ensure access to trained physicians. In some cases, the need to limit the size of the population prompted the use of contraceptive measures, and surviving information also illuminates attitudes to deformity, disability and the treatment of the terminally ill.

Is there a ghost in the machine? Are we born trailing clouds of glory? Is there a part of us that will survive death? Is the soul reborn in different bodily forms? These and similar questions have occupied humankind since the dawn of consciousness. Rosalie Osmond's book explores the way the soul has been represented in different cultures and at different times, from ancient Egypt and Greece, through medieval Europe and into the 21st century. Basing her approach on historical (...) sources, she reveals the many different ways in which the soul has been imagined and the range of human needs and aspirations these imaginings have addressed.

Rapidly advancing studies on rhodopsin have focused on new strategies for crystallization of this integral membrane protein for x-ray analysis and on alternative methods for structural determination from nuclear magnetic resonance data. Functional studies of the interactions between the apoprotein and its chromophore have clarified the role of the chromophore in deactivation of opsin and in photoactivation of the pigment.

Preserved human remains from ancient Egypt provide an unparalleled opportunity for studies in the history of disease and medical practices. Egyptian medical papyri describe physiological concepts, disease diagnoses and prescribed treatments which include both ‘irrational’, and ‘rational’ procedures. Many previous studies of Egyptian medicine have concluded that ‘irrational’ methods predominated, but this perception is increasingly challenged by results from scientific studies of ancient human remains, and plant materials. This paper demonstrates the significant contribution being made by multidisciplinary studies to our (...) understanding of disease occurrence and medical treatments in ancient Egypt, and considers the feasibility of developing epidemiological comparisons of ancient and modern data sets that will provide acceptable historical contexts for contemporary disease studies.

We present a basis for the admissible rules of intuitionistic propositional logic. Thereby a conjecture by de Jongh and Visser is proved. We also present a proof system for the admissible rules, and give semantic criteria for admissibility.

This paper contains a detailed account of the notion of admissibility in the setting of consequence relations. It is proved that the two notions of admissibility used in the literature coincide, and it provides an extension to multi–conclusion consequence relations that is more general than the one usually encountered in the literature on admissibility. The notion of a rule scheme is introduced to capture rules with side conditions, and it is shown that what is generally understood under the extension of (...) a consequence relation by a rule can be extended naturally to rule schemes, and that such extensions capture the intuitive idea of extending a logic by a rule.

Admissible rules of a logic are those rules under which the set of theorems of the logic is closed. In this paper, a Gentzen-style framework is introduced for analytic proof systems that derive admissible rules of non-classical logics. While Gentzen systems for derivability treat sequents as basic objects, for admissibility, the basic objects are sequent rules. Proof systems are defined here for admissible rules of classes of modal logics, including K4, S4, and GL, and also Intuitionistic Logic IPC. With minor (...) restrictions, proof search in these systems terminates, giving decision procedures for admissibility in the logics. (shrink)

We investigate the logical structure of intuitionistic Kripke-Platek set theory , and show that the first-order logic of is intuitionistic first-order logic IQC.

This paper contains a brief overview of the area of admissible rules with an emphasis on results about intermediate and modal propositional logics. No proofs are given but many references to the literature are provided.

This paper contains a proof-theoretic account of unification in transitive reflexive modal logics, which means that the reasoning is syntactic and uses as little semantics as possible. New proofs of theorems on unification types are presented and these results are extended to negationless fragments. In particular, a syntactic proof of Ghilardi’s result that $\mathsf {S4}$ has finitary unification is provided. In this approach the relation between classical valuations, projective unifiers, and admissible rules is clarified.

We present a basis for the admissible rules of intuitionistic propositional logic. Thereby a conjecture by de Jongh and Visser is proved. We also present a proof system for the admissible rules, and give semantic criteria for admissibility.

We investigated the properties of the sustained attention to response task . In the SART, participants respond to frequent neutral signals and are required to withhold response to rare critical signals. We examined whether SART performance shows characteristics of speed–accuracy tradeoffs and in addition, we examined whether SART performance is influenced by prior exposure to emotional picture stimuli. Thirty-six participants in this study performed SARTs after being exposed to neutral and negative picture stimuli. Performance in the SART changed rapidly over (...) time and there was a high correlation between participants errors of commission rate and their reaction time to the neutral targets . Regardless of exposure self-reported thoughts significantly correlated with both errors of commission and reaction times. Overall, the results support the view that the SART is a better measure of impulsive responding than sustained attention. (shrink)

In this paper we prove that three of the main propositional logics of dependence, none of which is structural, are structurally complete with respect to a class of substitutions under which the logics are closed. We obtain an analogous result with respect to stable substitutions, for the negative variants of some well-known intermediate logics, which are intermediate theories that are closely related to inquisitive logic.

If the Visser rules are admissible for an intermediate logic, they form a basis for the admissible rules of the logic. How to characterize the admissible rules of intermediate logics for which not all of the Visser rules are admissible is not known. In this paper we give a brief overview of results on admissible rules in the context of intermediate logics. We apply these results to some well-known intermediate logics. We provide natural examples of logics for which the Visser (...) rule are derivable, admissible but nonderivable, or not admissible. (shrink)

A method is presented that connects the existence of uniform interpolants to the existence of certain sequent calculi. This method is applied to several modal logics and is shown to cover known results from the literature, such as the existence of uniform interpolants for the modal logic \. New is the result that \ has uniform interpolation. The results imply that for modal logics \ and \, which are known not to have uniform interpolation, certain sequent calculi cannot exist.
