SummaryPedigree structures of 161 uncle/niece-aunt/nephew and 4420 first cousin consanguineous marriages registered during the 19th and 20th centuries in two large and very different Spanish regions have been analysed and their genetic consequences evaluated. The frequencies of the different pedigree subtypes within each degree of relationship were quite similar in both populations despite significant heterogeneity in inbreeding patterns. The mean X-linked inbreeding coefficient for each type of cousin mating was calculated and compared to that expected for autosomal genes. The effect (...) of genealogical structure on theFx/Fradio was compared to different cultural populations worldwide. Preferentiality and avoidance of close consanguinity along with specific types of pedigrees are discussed on the basis of premarital migration and sociocultural rules still deeply rooted in certain human groups. By admitting that the observedFxcoefficient is usually higher thanFin most human populations some remarks have been made in terms of population genetic risk. (shrink)

This paper presents the story of an isiXhosa traditional healer, Nomzi Hlathi, as told to the first author. Nomzi was asked about how she came to be an igqirha and the narrative focuses on those aspects of her life story that she understood as relevant to that developmental process. The material was obtained from a series of semi-structured interviews with Nomzi, with some collateral from her cousin, and synthesised into a chronological narrative presented in Nomzi’s own words. The aim of (...) the study was to examine her account of her unfolding experience within three hermeneutic frames. The first is the isiXhosa traditional account of what it is to become an igqirha, a process initiated by intwaso, an illness understood to be a call from the ancestors, and guided by messages from the ancestors in dreams and other symbolic communications. The second is the perspective of Western Clinical Psychology on the cognitive, emotional and behavioural disturbances that characterise intwaso. The third is the perspective of transpersonal psychology on the nature and development of shamanic healing gifts, as understood from observations of such practices in traditional societies across the world. As the narrative of Nomzi’s story is quite long, this paper presents her narrative as well as the methodology which gave rise to it. The interpretative review of the material from each of the three perspectives is presented in a second paper. (shrink)

Bioethicists often draw sharp distinctions between hope and states like denial, self-deception, and unrealistic optimism. But what, exactly, is the difference between hope and its more suspect cousins? One common way of drawing the distinction focuses on accuracy of belief about the desired outcome: Hope, though perhaps sometimes misplaced, does not involve inaccuracy in the way that these other states do. Because inaccurate beliefs are thought to compromise informed decision making, bioethicists have considered these states to be ones where intervention (...) is needed either to correct the person’s mental state or to persuade the person to behave differently, or even to deny the person certain options. In this article, we argue that it is difficult to determine whether a patient is really in denial, self-deceived, or unrealistically optimistic. Moreover, even when we are confident that beliefs are unrealistic, they are not always as harmful as critics contend. As a result, we need to be more permissive in our approach to patients who we believe are unrealistically optimistic, in denial, or self-deceived—that is, unless patients significantly misunderstand their situation and thus make decisions that are clearly bad for them, we should not intervene by trying to change their mental states or persuade them to behave differently, or by paternalistically denying them certain options.

Both fairness and efficiency are important considerations in market design and regulation, yet many regulators have neither defined nor measured these concepts. We develop an evidencebased policy framework in which these are both defined and measured using a series of empirical proxies. We then build a systems estimation model to examine the 2003–2011 explosive growth in algorithmic trading on the London Stock Exchange and NYSE Euronext Paris. Our results show that greater AT is associated with increased transactional efficiency and reduced (...) information leakage in top quintile stocks. For less liquid stocks, manipulation at the close declines. We also document the tradeoff between reduced spreads and increased manipulation or information leakage following the introduction of MiFID1. (shrink)

It is a pleasure for me to give this opening address to the Royal Institute of Philosophy Conference on ‘Explanation’ for two reasons. The first is that it is succeeded by exciting symposia and other papers concerned with various special aspects of the topic of explanation. The second is that the conference is being held in my old alma mater, the University of Glasgow, where I did my first degree. Especially due to C. A. Campbell and George Brown there was (...) in the Logic Department a big emphasis on absolute idealism, especially F. H. Bradley. My inclinations were to oppose this line of thought and to espouse the empiricism and realism of Russell, Broad and the like. Empiricism was represented in the department by D. R. Cousin, a modest man who published relatively little, but who was of quite extraordinary philosophical acumen and lucidity, and by Miss M. J. Levett, whose translation of Plato's Theaetetus formed an important part of the philosophy syllabus. (shrink)

Kendall's (1956) approach to the general epidemic is generalized by dropping the assumptions of constant infectivity and random recovery or death of ill individuals. A great deal of attention is paid to the biological background and the heuristics of the model formulation. Some new results are: (l) the derivation of Kermack's and McKendrick's integral equation from what seems to be the most general set of assumptions in section 2.2, (2) the use of Kermack's and McKendrick's final value equation to arrive (...) at a finite time version of the threshold theorem for the general case, comparable to that for the case of only one Markovian state of illness in section 2.5, (3) the analysis of the behaviour of the solutions of the integral equation when the starting infection approaches zero in section 2.7, (4) the derivation of the probability structure of a general branching process, after conditioning on extinction in section 3.6, (5) the statement of the generalized versions of Kendall's ideas in the form of precise limit conjectures in section 4, (6) the derivation of a closed expression for the limit epidemic resulting from (3) in appendix 4.

La parole est l'entre-deux qui sépare et unit moi et le monde, moi et toi, moi et moi-même. On se demande quelle est la relation entre moi et ma parole, si la parole découle de l'essence même de mon être. Une analyse phénoménologique, qui partirait du dialogue comme d'un donné indubitable, ne suffit pas tout à fait, puisqu'il il s'agit d'un sens éventuel du dialogue pour le tout de mon être. Il faut donc aborder la question d'un point de vue (...) d'où le dialogue lui-même est mis en suspens. Commençons par l'indubitable absolu : l'être. Il y a quelque chose, quoi que ce soit, il y a au moins la question même de l'être. Mais cette question qui se met elle-même en question, se sait être. Et qu'est cela sinon moi-même, pas encore opposé, il est vrai, à toi, à lui, à nous ? Pourtant je ne suis pas l'être ; il y a en moi une dualité entre essence et être, et une dualité entre être et penser. Je sais que je suis, je cherche encore qui je suis. Eh bien, je suis « ici et maintenant » , c. à. d. je suis dans un ordre spatio-temporel, par mon corps, qui est donc ce qui m'exprime à moi-même, ma parole. Mais mon corps est originellement en commerce avec les êtres du monde, et j'ai le sentiment de cette situation par la perception et le comportement. En révélant le sens des êtres du monde, en leur donnant des noms de mon point de vue, je me nomme moi-même. En revenant sur la voie parcourue jusqu'ici, l'article démontre que ce n'est pas seulement mon monde que je nomme. Le « moi » de la certitude absolue est un « nous » pas encore détaillé. Et à l'intérieur de ce « nous » jaillit, par ta foi en moi, l'opposition communicative entre moi et toi, que j'expérimente surtout dans la corrélation de la voix et de l'ouïe. La parole fonde la communauté, puisqu'en exprimant mon être elle s'adresse à vous, et manifeste ainsi mon être comme « être-avec » . L'être même est infini, et donc communicabilité pure, et donc parole. Mais notre parole humaine n'est que participation déficiente de la communication immédiate qui serait l'identité de l'être, le connaître et l'aimer. Elle reste moyen, et donc succédané de l'immédiat, et donc ambigue. Notre dialogue doit se transcender dans l'inexprimable, dans le silence. La parole essentielle, la parole de l'amour, est pour les hommes la parole la plus dangereuse et la plus incertaine. Elle ne se prouve que par la fidélité. Mais tout ce que nous disons et faisons est destiné à devenir l'incarnation de cette parole. (shrink)

Chancy counterfactuals are a headache. Dylan Dodd (2009) presents an interesting argument against a certain general strategy for accounting for them, instances of which are found in the appendices to Lewis (1979) and in Williams (2008). I will argue (i) that Dodd’s understates the counterintuitiveness of the conclusions he can reach; (ii) that the counterintuitiveness can be thought of as an instance of more general oddities arising when we treat vagueness and indeterminacy in a classical setting; and (iii) the underlying (...) source of discontent which animates Dodd’s complains is to be found in a certain general constraint one might impose on conditionals—what I’ll call the counterfactual Ramsey bound. Unfortunately, the counterfactual Ramsey bound is just as problematic as its famous indicative cousin. The moral is that there’s no comfortable resting place in this area; for violations of the counterfactual Ramsey bound are going to lead to prima facie surprising results. (shrink)

The author deals with the meaning of metamerism. Two contrary points of view may serve to clear the problem. From the morphological point of view probably outgrowth of the organism in longitudinal direction has led to the development of metameres. So the first segmentation is due to a functional differentiation. In Phylogeny this segmentation has been maintained and the originally developed metameres remain the primary morphotic units of the organisms. Further specialising of function and organ-concentration destroyed the original absolute metamerism (...) and only left a rest of the original.The functional point of view renounces an original absolute metamerism for the present moment. It only asks for the functional meaning of the segmentation in organisms, showing this segmentation. From the functional point of view it is possible that metamerism may be the morphological expression of quite different functional requirements and that in one organism the metamerism starts from another system of organs than in another.Es wird gefragt welche Bedeutung die Metamerie haben kann. Zur Erläuterung des Problems werden zwei extremen Betrachtungsweisen einander gegenübergestellt. Nach der morphologischen Betrachtungsweise hat Wachstum der Organismen in die Länge wahrscheinlich zur Ausbildung der Metamerie geführt. Diese erste Metamerie ist wahrscheinlich ein funktioneller Differenzierungsprozess gewesen.In der Phylogenese hat sich diese Metamerie behauptet und die ursprünglich entstandene Metamere sind die primären morphotischen Einheiten der Organismen geblieben. Weitergehende Funktionsspezialisierung und Organkonzentration hat die ursprüngliche absolute Metamerie vernichtet. Was davon übrig blieb sind die Reste der ursprünglichen.Die funktioneile Betrachtungsweise verzichtet vorläufig auf eine ursprüngliche absolute Metamerie. Sie fragt bloss nach der funktionellen Bedeutung, welche die Metamerie besitzt bei denjenigen Organismen, wo diese gefunden wird. Sie achtet es möglich, dass Metamerie der Ausdruck sein kann von ganz verschiedenen funktionellen Anforderungen und dass somit die Metamerie bei der einen Tiergruppe von einem ganz anderen Organsystem ausgeht wei bei einer anderen.

Barbey & Sloman's (B&S's) base-rate respect model is anticipated by Reyna's denominator neglect model. There are parallels at three levels: (a) explanations are grounded in a general cognitive theory (rather than in domain-specific ideas); (b) problem structure is treated as a key source of reasoning errors; and most importantly, (c) nested set relations are seen as the cause of base-rate neglect.

If in the various books of the Iliad and Odyssey the speeches or personated lines are separated from the rest, the metrical phenomena will, when tabulated, be found to show a perceptible divergence from those of the narrative verse. The differences are worth some notice. They throw into sharp relief the subtle rules that control the narrative type; and, what is more important, they do to some extent suggest the principle, of which these rules are the necessary outcome. There is (...) also involved another point of considerable interest; for the contrast between narrative- and speech-verse exactly coincides, it must be remembered, with a very remarkable difference in the use of the augment; and the more this coincidence is considered, the less easy it will be found to dismiss it as accidental.

The use of the temporal augment in narrative we have found to be purely scansional. Scansional, too, is the use of the syllabic, though this has a grammatical restriction which is of some interest; indeed, next to the maintenance of type öρovδΕ, it is the most vital fact for the whole question. The unaugmented aorist is not felt as an inflection which has been docked of its first syllable; quite the reverse, the augmented tense is treated as a compound. For (...) example, é normally stands second in its clause; and so, if the syllabic augment was still consciously regarded as what it really is—viz. an adverb in composition—we should expect to see a great unwillingness to place Be after a tense thus augmented. Our expectation is fully borne out by the text; in the whole narrative of the Iliad there are only sixteen sure examples of é standing after the syllabically augmented aorist. (shrink)

Though the problem of the Homeric augment eventually needs a rather intricate handling, it can at first be stated quite simply. Briefly, the facts are these:A. True present-aorists, such as are seen in the similes and gnomes, take the augment idiomatically. In the whole of the similes there are only sixteen unaugmented aorists; three of the instances are difficult, but the rest could be emended by slight changes.B.Iteratives do not take the augment; ν 7 is the only certain exception.

We inhabit a world in which the market is a dominant institutional form of social organization. This influence is not without its critics, and there is considerable debate amongst political philosophers and policy-makers about whether the range of the market should expand or contract and, further, about the extent to which the market should be subject to constraints and government regulation. The expansion of the market into realms hitherto unknown is the theme of a number of recent books, including Michael (...) Sandel's What Money Can't Buy and Debra Satz's Why Some Things Should Not Be for Sale, which build on earlier work by, amongst others, Elizabeth Anderson, Margaret Jane Radin, and Michael Walzer.

Infinite time Turing machines with only one tape are in many respects fully as powerful as their multi-tape cousins. In particular, the two models of machine give rise to the same class of decidable sets, the same degree structure and, at least for partial functions f : ℝ → ℕ, the same class of computable functions. Nevertheless, there are infinite time computable functions f : ℝ → ℝ that are not one-tape computable, and so the two models of infinitary computation (...) are not equivalent. Surprisingly, the class of one-tape computable functions is not closed under composition; but closing it under composition yields the full class of all infinite time computable functions. Finally, every ordinal that is clockable by an infinite time Turing machine is clockable by a one-tape machine, except certain isolated ordinals that end gaps in the clockable ordinals. (shrink)

A number of recent papers have described the successful derivation of egg and sperm precursor cells from mouse embryonic stem cells—so-called “artificial” gametes. Although many scientific questions remain, this research suggests numerous new possibilities for stem cell research and assisted reproductive technology, if a similar breakthrough is achieved with human embryonic stem cells. The novel opportunities raised by artificial gametes also prompt new ethical questions, such as whether same-sex couples should be able to access this technology to have children who (...) are genetically related to them both.THE CREATION OF “ARTIFICIAL” GAMETESOver the past two years, a number of papers have been published detailing the first successful attempts at differentiating mouse embryonic stem cells into egg1 and sperm2 precursor cells. Previously, researchers had used embryonic stem cells to generate tissues such as brain, liver, and pancreatic cells, but not germ cells of any kind. Production of gamete precursor cells was achieved initially through allowing stem cell lines to differentiate more or less randomly, but recent research has focused on identifying the precise ways in which differentiation into gametes can be precipitated and controlled. These breakthroughs make it seem likely that ongoing research on human stem cells will yield similar possibilities,3 raising questions over the practicalities of what might be achieved with such “artificial” gametes. In turn, the novel opportunities presented by artificial gametes raise a number of ethical concerns.The initial breakthrough, namely the obtaining of egg cells from mouse stem cells, was achieved by means of relatively simple science. Rather than coaxing stem cells to develop into eggs using complicated cocktails of growth factors, researchers adopted standard cell culture conditions, but grew the cells at higher density than usual.3–6 Growing the cells in this way led to the formation of ovary-like cell aggregates, which (when separated and stimulated with ….

Much of the progress in the fields constituting cognitive science has been based upon the use of explicit information processing models, almost exclusively patterned after conventional serial computers. An extension of these ideas to massively parallel, connectionist models appears to offer a number of advantages. After a preliminary discussion, this paper introduces a general connectionist model and considers how it might be used in cognitive science. Among the issues addressed are: stability and noise‐sensitivity, distributed decision‐making, time and sequence problems, and (...) the representation of complex concepts. (shrink)

For days and days he had lived only by the aid of enormous quantities of oxygen. Yesterday alone he had consumed forty containers, at six francs apiece — that mounted up, the gentlemen could reckon the cost themselves; and his wife, in whose arms he had died, was left wholly penniless. Joachim expressed disapproval of this expenditure. Why delay by these torturing and costly artificial expedients a death absolutely certain to supervene? One could not blame the man for blindly consuming (...) the precious gas they urged upon him. But those in charge should have behaved with more reason, they should have let him go his way, in God's name, quite aside from the circumstances, more so when taking them into consideration. The living, after all, had their rights — and so on. Hans Castorp disagreed emphatically. His cousin, he said, talked almost like Settembrini, without regard or reverence for suffering. The man had died in the end, that finished it; there was no more to be done to show one's concern, and it had been due to the dying to spend what one could. Thus Hans Castorp" (1, p 291). (shrink)

Moral judgments can occur either in settings that call for impartiality or in settings that allow for partiality. How effective are impartiality settings such as hospitals in suppressing personal biases? Portrayed as decision-makers in an emergency department, 431 college students made judgments on which of two victims of a mass shooting should receive immediate, life-saving care. Patients differed in ways that could reveal biases, e.g., age, kinship, gender, and villain/hero. Participants rated each patient’s moral deservingness to receive immediate care and (...) the likelihood they would choose the patient. Both scales showed young favored over old, cousin over stranger, and policeman over shooter. In a hospital-room scenario with high risk of injury from falling, age bias disappeared. With moderate fall risk, age bias reversed and kinship deservingness bias disappeared. Bias decreases when there is a decrease in severity of potential harm to the preferred stakeholder. Settings that call for impartiality are not reliable “boundary conditions” against expressions of bias. In the absence of explicit guidelines for allocating scarce resources, a systematic, objective method of random selection offers a potentially useful strategy. (shrink)

In the late 1800s, Charles Darwin and other naturalists supported a blending view of inheritance whereby offspring possess a middling mix of their parents' traits. Many of these naturalists also argued that individuals pass at least some of their acquired characteristics to their descendants. Darwin proposed that acquired characteristics and other environmentally induced changes in a parent's hereditary material account in large part for the inheritable variations that drove evolution. Inspired by the evolutionary theories of his first cousin, Darwin, Francis (...) Galton developed hereditarian notions that helped to lay the foundation for both genetics and eugenics. Eugenics was endorsed by evolutionary geneticists such as August Weismann, Karl Pearson, W. F. R. Weldon, William Bateson, and Hugo de Vries, which, as a result, gave it enormous scientific credibility in America and Europe. This chapter explores the role of biology in the emergence of the eugenics movement in the Anglo-Saxon world. (shrink)
