In [3], two different effective versions of Borel embedding are defined. The first, called computable embedding, is based on uniform enumeration reducibility, while the second, called Turing computable embedding, is based on uniform Turing reducibility. While [3] focused mainly on computable embeddings, the present paper considers Turing computable embeddings. Although the two notions are not equivalent, we can show that they behave alike on the mathematically interesting classes chosen for investigation in [3]. We give a “Pull-back Theorem”, saying that if (...) Φ is a Turing computable embedding of K into K’, then for any computable infinitary sentence φ in the language of K’, we can find a computable infinitary sentence φ* in the language of K such that for all.

The first main result isolates some conditions which fail for the class of graphs and hold for the class of Abelian p-groups, the class of Abelian torsion groups, and the special class of "rank-homogeneous" trees. We consider these conditions as a possible definition of what it means for a class of structures to have "Ulm type". The result says that there can be no Turing computable embedding of a class not of Ulm type into one of Ulm type. We apply (...) this result to show that there is no Turing computable embedding of the class of graphs into the class of "rank-homogeneous" trees. The second main result says that there is a Turing computable embedding of the class of rank-homogeneous trees into the class of torsion-free Abelian groups. The third main result says that there is a "rank-preserving" Turing computable embedding of the class of rank-homogeneous trees into the class of Boolean algebras. Using this result, we show that there is a computable Boolean algebra of Scott rank ${\mathrm{\omega }}_{1}^{\mathrm{C}\mathrm{K}}$. (shrink)

In Nicolaus Cusanus on Faith and the Intellect: A Case Study in 15th-Century Fides-Ratio Controversy, K.M. Ziebart presents an account of the Cusan epistemology as a fascinating late-medieval attempt to definitively harmonize faith and reason.

This paper calculates, in a precise way, the complexity of the index sets for three classes of computable structures: the class $K_{\omega _{1}^{\mathit{CK}}}$ of structures of Scott rank $\omega _{1}^{\mathit{CK}}$ , the class $K_{\omega _{1}^{\mathit{CK}}+1}$ of structures of Scott rank $\omega _{1}^{\mathit{CK}}+1$ , and the class K of all structures of non-computable Scott rank. We show that I(K) is m-complete $\Sigma _{1}^{1},\,I(K_{\omega _{1}^{\mathit{CK}}})$ is m-complete $\Pi _{2}^{0}$ relative to Kleen's O, and $I(K_{\omega _{1}^{\mathit{CK}}+1})$ is m-complete $\Sigma _{2}^{0}$ relative to O.

Narrative ethics taps into an inherent human need to tell our own stories centred on our own moral values and to have those stories heard and acknowledged. However, not everyone’s words are afforded equal power. The use of narrative ethics in bioethical decision-making is problematized by a disparity in whose stories are told, whose stories are heard, and whose stories are believed. Here, I conduct an analysis of narrative ethics through a critical theory lens to show how entrenched patterns of (...) narrative neglect in medicine are harming not only our capacity to make use of narrative ethics but also our capacity to deliver effective healthcare. To illustrate this point, I use three examples where the patient’s gender affects how their stories unfold: autism, weight, and pain management. From these, I argue that the use of narrative ethics without the application of a critical theory lens risks the exacerbation of what Miranda Fricker refers to as “testimonial injustice,” the prima facie harm experienced by individuals whose credibility is undermined by others’ prejudices. Finally, I suggest that narrative ethics can be a powerful tool for mitigating oppressive practices in medicine if we couple it with critical analysis that enables us to understand the power dynamics at play in storytelling.

This paper raises the questions: 'What do we expect from nursing ethics?' and 'Is the literature of nursing ethics any different from that of medical ethics?' It is suggested that rather than develop nursing ethics as a separate field writers in nursing ethics should take a lead in making the patient the central focus of health care ethics. The case is made for empirical work in health care ethics and it is suggested that a good way of setting about this (...) is to ask practising nurses about the real ethical problems they encounter.

This essay discusses an alternative interpretation of the term “Dasein” as Heidegger uses it in Being and Time and, in particular, the possibility that Dasein is meant to contain an inherent form of intersubjectivity to which we must “return” in order to achieve authenticity. In doing so, I build on the work of John Haugeland and his interpretation of Dasein as a mass term, while exploring the implications such an interpretation has on Heidegger’s conception of “authenticity”. Ultimately, this paper aims (...) to take seriously Heidegger’s claim to be moving past the isolated Cartesian subject and towards a view of authentic human existence that is cognizant of the way our identities are always formed within a pre-existing community. In addition, since many interpretations of Heidegger have argued that “the Anyone” is representative of all possible forms of community, I consider how this alternative understanding of Dasein as intersubjective can shed new light on critical remarks Heidegger makes about “the Anyone”. Thus, I argue that by reinterpreting Dasein as community, we can find more coherence between Heidegger’s otherwise conflicting conceptions of authenticity and “the Anyone”. (shrink)

Although science supplies medicine's “gold standard,” knowledge exercised in the care of patients is, like moral knowing, a matter of narrative, practical reason. Physicians draw on case narrative to store experience and to apply and qualify the general rules of medical science. Literature aids in this activity by stimulating moral imagination and by requiring its readers to engage in the retrospective construction of a situated, subjective account of events. Narrative truths are provisional, uncertain, derived from narrators whose standpoints are always (...) situated, particular, and uncertain, but open to comparison and reinterpretation. Reading is thus a model for knowing in both morality and clinical medicine. While principles remain essential to bioethics and science must always inform good clinical practice, the tendency to collapse morality into principles and medicine into science impoverishes both practices. Moral knowing is not separable from clinical judgment. While ethics must be open to discussion and interpretation by patients, families, and society, it is nevertheless substantively and epistemologically an inextricable part of a physician's clinical practice.

Objective To study how doctors care for their patients, both medically and as fellow humans, through observing their conduct in patient–doctor encounters. Design Qualitative study in which 101 videotaped consultations were observed and analysed using a Grounded Theory approach, generating explanatory categories through a hermeneutical analysis of the taped consultations. Setting A 500-bed general teaching hospital in Norway. Participants 71 doctors working in clinical non-psychiatric departments and their patients. Results The doctors were concerned about their patients' health and how their (...) medical knowledge could be of service. This medical focus often over-rode other important aspects of the consultations, especially existential elements. The doctors actively directed the focus away from their patients' existential concerns onto medical facts and rarely addressed the personal aspects of a patient's condition, treating them in a biomechanical manner. At the same time, however, the doctors attended to their patients with courteousness, displaying a polite and friendly attitude and emphasising the relationship between them. Conclusions The study suggests that the main failing of patient–doctor encounters is not a lack of courteous manners, but the moral offence patients experience when existential concerns are ignored. Improving doctors' social and communication skills cannot resolve this moral problem, which appears to be intrinsically bound to modern medical practice. Acknowledging this moral offence would, however, be the first step towards minimising the effects thereof. (shrink)

Medical ethics, principles, persons, and perspectives is discussed under three headings: History, Theory, and Practice. Under Theory, the author will say something about some different approaches to the study and discussion of ethical issues in medicine—especially those based on principles, persons, or perspectives. Under Practice, the author will discuss how one perspectives based approach, hermeneutics, might help in relation first to everyday ethical issues and then to public controversies. In that context some possible advantages of moving from controversy to conversation (...) will be explored; and that will then be illustrated with reference to a current controversy about the use of human embryos in stem cell therapy research. The paper begins with history, and it begins in the author’s home city of Edinburgh. (shrink)

Immediately after the publication of Darwin's book on the origin of species, Engels, having familiarized himself with it, wrote to Marx on December 12, 1859: "All in all, Darwin, whom I am reading right now, is superb. Teleology had hitherto not yet been destroyed in one of its aspects, and now this has been done. Moreover, hitherto there has never been so sweeping an attempt to prove historical development in nature, especially with such success." Soon Marx enlarged upon the evaluation (...) of Darwinism. In his letter of December 19, 1860, he commented that this theory "provides a foundation in natural history for our views." It is therefore no accident that Engels, in developing the principles of dialectical materialism and problems of the dialectics of nature, interested himself so deeply and comprehensively in the theory of evolution.

An Institute of Medical Ethics working party argues that an ethically desirable relationship of mutual empowerment between patient and clinician is more likely to be achieved if patients understand the ground rules of medical confidentiality. It identifies and illustrates ambiguities in the General Medical Council's guidance on AIDS and confidentiality, and relates this to the practice of different doctors and specialties. Matters might be clarified, it suggests, by identifying moral factors which tend to recur in medical decisions about maintaining or (...) breaching confidentiality. The working party argues that two such factors are particularly important: the patient's need to exercise informed choice and the doctor's primary responsibility to his or her own patients. (shrink)

Investigation into the reality of time can be pursued within the ontological domain or it can also span human thought and natural language. I propose to approach time by correlating three domains of inquiry: metaphysical time, the human concept of time, and temporal reference in natural language, entertaining the possibility of what I call a ‘horizontal reduction’ and ‘vertical reduction’. I present a view of temporalityL/E as epistemic modality, drawing on evidence from the L domain and its correlates in the (...) E and M domains. On this view, the human concept of time is a complex, ‘molecular’ concept and can be broken down into primitive concepts that are modal in nature, featuring as degrees of epistemic commitment to representations of states of affairs. I present evidence from tensed and tenseless languages and point out its compatibility with the view of real time as metaphysical modality. (shrink)

Abortion is forbidden under normal circumstances by nearly all the major world religions. Traditionally, abortion was not deemed permissible by Muslim scholars. Shiite scholars considered it forbidden after implantation of the fertilised ovum. However, Sunni scholars have held various opinions on the matter, but all agreed that after 4 months gestation abortion was not permitted. In addition, classical Islamic scholarship had only considered threats to maternal health as a reason for therapeutic abortion. Recently, scholars have begun to consider the effect (...) of severe fetal deformities on the mother, the families and society. This has led some scholars to reconsider the prohibition on abortion in limited circumstances. This article reviews the Islamic basis for the prohibition of abortion and the reasons for its justification. Contemporary rulings from leading Shiite scholars and from the Sunni school of thought are presented and reviewed. The status of abortion in Muslim countries is reviewed, with special emphasis on the therapeutic abortion law passed by the Iranian Parliament in 2003. This law approved therapeutic abortion before 16 weeks of gestation under limited circumstances, including medical conditions related to fetal and maternal health. Recent measures in Iran provide an opportunity for the Muslim scholars in other countries to review their traditional stance on abortion. (shrink)

Cross-species comparisons are benefited by compatible datasets; conclusions related to phylogenetic comparisons, questions on convergent and divergent evolution, or homologs versus analogs can only be made when the behaviors being measured are comparable. A direct comparison of the social function of physical contact across two disparate taxa is possible only if data collection and analyses methodologies are analogous. We identify and discuss the parameters, assumptions and measurement schemes applicable to multiple taxa and species that facilitate cross-species comparisons. To illustrate our (...) proposed guidelines for evaluating the role played by tactile contact in social behavior across disparate taxa, this paper presents data on mother-offspring relationships in the two species studied by the authors: chimpanzees (Pan troglodytes schweinfurthii) and dolphins (bottlenose and spotted, Tursiops truncatus and Stenella frontalis, respectively). Cross-species comparative studies allow for a more comprehensive assessment of the similarities and differences with respect to how animals traverse the relationships that form their social groups and societies.

An Institute of Medical Ethics working party supports the view that explicit permission should normally be sought in the case of testing for HIV antibody. It discusses this in relation to anonymised HIV testing for epidemiological purposes, concluding that this is to be welcomed, given certain safeguards. It next argues that pregnant women may have a greater and more immediate need than others to know their HIV status. It concludes that this need does not justify testing them without their permission, (...) but can be met by voluntary diagnostic testing on an 'opting-out' basis, supported by adequate briefing.

The literature on Leonardo da Vinci is so extensive that a bibliography alone would make many volumes. Most of what has been written about him, however, are studies in history, art criticism, biography, or natural science. The number of writings on his esthetics and philosophy of culture are considerably fewer. And there are very few Marxist studies on these questions. This is particularly true of works devoted specifically to Leonardo alone.
