Precision Medicine is driven by the idea that the rapidly increasing range of relatively cheap and efficient self-tracking devices make it feasible to collect multiple kinds of phenotypic data. Advocates of N = 1 research emphasize the countless opportunities personal data provide for optimizing individual health. At the same time, using biomarker data for lifestyle interventions has shown to entail complex challenges. In this paper, we argue that researchers in the field of precision medicine need to address the performative dimension (...) of collecting data. We propose the fun-house mirror as a metaphor for the use of personal health data; each health data source yields a particular type of image that can be regarded as a ‘data mirror’ that is by definition specific and skewed. This requires competence on the part of individuals to adequately interpret the images thus provided. (shrink)

Monadic second order logic and linear temporal logic are two logical formalisms that can be used to describe classes of infinite words, i.e., first-order models based on the natural numbers with order, successor, and finitely many unary predicate symbols.Monadic second order logic over infinite words can alternatively be described as a first-order logic interpreted in${\cal P}\left$, the power set Boolean algebra of the natural numbers, equipped with modal operators for ‘initial’, ‘next’, and ‘future’ states. We prove that the first-order theory (...) of this structure is the model companion of a class of algebras corresponding to a version of linear temporal logic without until.The proof makes crucial use of two classical, nontrivial results from the literature, namely the completeness of LTL with respect to the natural numbers, and the correspondence between S1S-formulas and Büchi automata.

continent. 1.2 (2011): 129-135. Introduction Vincent W.J. van Gerven Oei Successions of words are so agreeable. It is about this. —Gertrude Stein Nachoem Wijnberg (1961) is a Dutch poet and novelist. He also a professor of cultural entrepreneurship and management at the Business School of the University of Amsterdam. Since 1989, he has published thirteen volumes of poetry and four novels, which, in my opinion mark a high point in Dutch contemporary literature. His novels even more than his poetry are (...) criticized for being inaccessible, which I generally take to be a compliment. It would be like saying that Fernando Pessoa is inaccessible, which he is not. Neither is Wijnberg. When we think of the combination economist-poet we are immediately reminded of the American poet Wallace Stevens, who, as the story goes, had two stacks of paper on his desk, one for contracts, one for poems. We also know that Stevens wrote on the economy and that questions of economy and insurance surface at multiple points in his poems. The following text is a very preliminary attempt to point at the intersections between poems, novels, business, and poetry in Wijnberg’s work. On the back cover of his novel De opvolging ( The Succession , 2005), Wijnberg states the following: “[This is] a novel for whomever is interested in the workings of a company as much as in the workings of a poem.” Wijnberg thus claims that the way in which a company “works” may be similar to the way in which a poem “works.” The question is the obvious one, what does this similarity consist in? De opvolging tells the story of company in which bosses and company doctors, secretaries, children, clowns, and beggars have tons of meetings, recite poems, perform plays, tell jokes, and succeed each other, climbing up and down in the company’s hierarchy. De opvolging is a novel in which the career of people follows the career of words. It resonates with Gertrude Stein's sentences, "Grammar. What is it. Who was it" (1975, 50). The words in Wijnberg's poems are like he characters in his novel. And if we keep in mind this allegorical reading of De opvolging , which is obviously only one of the possible readings, we may be able to understand some aspects of Wijnberg’s poetry. A repetition is already a pun. Look, that word is trying it again, as if it is afraid that by not doing it it would give up the hope that it will ever be able to do something. A pun is the opposite of the first word coming to the mind of someone who shouts it when he suddenly discovers something. (104) The repetition, the succession of the same word, is already a pun, a joke. The succession of the father by the son after the revolution is a joke. "Look he's trying it again!" The essence of a joke is a repetition. Archimedes’ “Eureka!” is its opposite. Poems can easily become jokes, depending on the way the words follow and repeat each other. In De opvolging , the careers of the bosses, good and bad secretaries, and company doctors easily become jokes, as they are “afraid that by not doing it [they] would give up the hope that [they] will ever be able to do something.” Not only the repetition, but also the distance and difference between the words in a poem, their cause and effect relations can be read as company relations. This becomes clear when we, for example, read the first lines of the poem “Cause, sign” from Het leven van ( The Life Of , 2009). A sign lets know what is going to happen, a cause lets it happen. If the sign also lets happen there is no reason to isolate it, because then I would isolate some- thing only because it’s different for me. If I didn’t have to write this myself, but would have secretaries to whom I could dictate it, I would be able to say more about it. (49) Upon reading the first two lines we can already conclude that any word may be cause or sign or both. If a sign is also a cause there is no reason to discriminate it, yet to the poet they are still different. This difference only becomes expressible the moment he would have a secretary. Just like in De opvolging , the secretary introduces a distance; not in a company but in a poem. Hence the difference between “good” and “bad” secretaries in a company, where the good secretary of one boss may be the bad secretary of another one. The more we can say about the bosses of the company, or signifiers of the poem, the greater the distance we introduce between them and us. We should take serious the relation between Wijnberg’s novels and poems. Although they operate on different scales, they explain and converse with each other. Another example may be the novel Politiek en liefde ( Politics and Love , 2002), which deals with the relation, precisely, between politics and love. In the novel, Nicolai, a lieutenant in the Dutch army, is sent to Africa on a military mission. Upon leaving a receives a letter from his father. Dear son, Don’t do anything stupid before your father has advised you to do so. Your mother asked me to write a wise letter. I have been looking for wisdom for half a day and haven’t found much. If you borrow a small amount from a bank you become the bank’s slave, but if you borrow a couple of millions and spend them as quickly as possible the bank becomes your slave. What I want to say is that you have to return from Africa in good health, and before you know it the world will be your slave [....] Signed with a kiss from your father. (88) The line, “If you borrow a small amount from a bank you become the bank’s slave, but if you borrow a couple of millions and spend them as quickly as possible the bank becomes your slave,” returns as the title of poem in Het leven van: “If I borrow enough money the bank becomes my slave” (12-3), which elaborates this theme. So both in the way that these poems are structured and in their subject matter, they refer to the structures of our economy, to the ever-continuing line of CEOs succeeding each other like words, to the distance between them introduced by bureaucracy, and giving and receiving as economical and poetical acts. Poem and economy map onto each other, as in another episode from De opvolging : Edward reads two of the beggar’s poems about presents. Of a holiday nothing remains, except for memories, and if some of them are bad I’d rather forget them all; if I get a present I’d rather get something that’s useful to me for a long time. If I may choose, I choose what I can use longest, long enough to partially forget that this was the present, because it feels bad when nothing is left of it. […] Giving away becomes destruction in the stock destruction economy [ voorraadvernie -tigings-economie ], that is a gift economy [ geschenkeneconomie ], encountering for the first time an economy in which there’s selling and buying on markets. Instead of destroying supplies someone can also quickly say that they aren’t worth anything anymore; if someone wants to take them I’d gladly give him something extra. In a stock destruction economy he is someone who each day wants to work more hours than his colleagues. If around a company there is a gift economy in which someone’s rank is determined and made visible by the gifts someone can give someone else, a company will be more often character- ized by an invisible or unclear system of ranks. (152) Two poems about gifts present two different economical models, described by Wijnberg with the terms “stock destruction economy” and “gift economy.” Here we immediately recall the opposition introduced by George Bataille’s work on the concept of expenditure in The Accursed Share , where a “general economy” would surpass the stock destruction economy based on scarcity (capitalism) and become a gift economy (potlatch) and an egalitarian (communist) society. These claims are made both on the level of the poems and in their discursive explanation. They follow each other and on each other. I would like to finish this introduction to Wijnberg’s writing with a translation from his novel De joden ( The Jews , 1999), which develops the story of Hitler abdicating as chancellor of the Third Reich, appointing philosopher Martin Heidegger as his successor. In a conversation with two Russian actor-spies, sent by Stalin to figure out the situation, philosopher Walter Benjamin describes the abdication scene. Maimon: You were there when Hitler resigned? Benjamin: In the room we’re right now. The desk and the chairs are new. After his resignation Hitler would like to take his furniture to his new house. Martin naturally agrees. It is a sunny day. Martin is very nervous and complains about the heat. Martin is wearing his best dark blue suit, not his professor’s robe. Hitler is wearing his uniform. We enter the room and Hitler gets up and embraces Martin. Martin is not very good at embracing. Hitler shakes his hand. Hitler’s cap is on the desk. The cap has a metal lining. Hitler has strong neck muscles. Hitler says: A man is unclean. He takes a bath. Does he make the bath water unclean? I say: a man is unclean. He steps into a river. A little further a man steps into the river; does he become unclean? Hitler nods. I say: a man is standing in music. Another man hears the music but also sees the first man moving on the beat of the music in a way that he is certain that the music would excite different feelings in him if he wouldn’t to see the first man. Hitler says: a man is clean, listens to music, is suddenly touched and he doesn’t know by what. The conversation ends in the way you know it ends. Hitler picks up his cap from the desk and puts it on Martin’s head. (73-4) Aware of the never ending debate on the question of Heidegger’s involvement in the Nazi regime, Wijnberg has the audacity to present the arguments of complicity in the religious terminology of cleanliness and uncleanliness, while at the same time recalling overtones of Hitler’s supposed love for Wagner, suggesting a relation between Benjamin and Hitler, and so on. The space of this introduction is to small to treat a novel like De joden , a reading of which together with passages from Philippe Lacoue-Labarthe's Heidegger, Art, and Politics: The Fiction of the Political , Jacques Derrida's Of Spirit , Christopher Fynsk's Heidegger: Thought and Historicity , and Avital Ronell's The Telephone Book would be extremely elucidating and potentially open new avenues in thinking Heidegger's emphasis on poetry after the fall of the Nazi empire. But at this point we will have to curb our curiosity and follow the poet himself. The themes of the relation between business and poetry, but also Chinese landscape painting, love, Indian and Japanese poetry, and Western philosophy are analyzed and assimilated in Wijnberg’s work without ever losing the clarity of expression. It may be that, according to Alain Badiou, the “Age of the Poets” is over, but its end (Paul Celan) has exactly brought a new balance between philosophy and poetry, and it is this playful, but nonetheless serious balance that makes one hope that one day Wijnberg’s complete oeuvre might become available to readers across the planet. Tiranë, Albania February 15, 2011 English translations (all of them translated by David Colmer, who is preparing an English collection of Wijnberg’s poems entitled Advanced Payment ): Poetry International Words Without Borders Green Integer Review from Het leven van ( The Life of ) THE LIFE OF KANT, OF HEGEL As if every day he takes a decision that is as good as when he’d been able to think about it all his life. The life of Kant, of Hegel, the days of the life of, select three or four of them. Tell what he has discovered during those days as if he were the last one who knew so little. Give me something that I can cancel against then I can prepare myself for it. The reward is that I may continue with what I’m doing, it doesn’t matter how long it takes. This has nothing to do with everything remaining the same if I say that I no longer want anything else. I wouldn’t be able to say in which one and the other occur in a way that I if I knew something to cancel that one against it wouldn’t be possible now. The stars above my head and being able to say what belongs to what if I’ve let them in. FOLLOWING MY HEART WITHOUT BREAKING THE RULES Observing the rules without observing the rules by going where the rules no longer apply. I could also observe the rules there by applying them to what at great distance may resemble what the rules are about. But why would I do that, not to confuse someone who is seeing me from a great distance? Behind this morning the morning prepares itself when the rules are everything I have. IF I BORROW ENOUGH MONEY THE BANK BECOMES MY SLAVE A bank lends me money, if I don’t pay it back they tell my boss that he has to pay them my salary. But they have to leave me enough to eat and sleep and an umbrella when it’s raining. They can also empty my house, the furniture isn’t worth a lot, but every little helps. Each morning I leave for work, if I don’t start early they’ll soon get someone else, no bank will lend me money when the sun is shining. My boss has given me a cat to raise as a dog. Of course I know that it won’t work out, but I’ve asked for a week—maybe the cat gets lucky, maybe I get lucky. My hands around a cup of coffee, before I leave for work, warm-empty, cold-empty, as if hidden in the mist over a lawn. What I make when there’s no work left for me, I’m ashamed to say how little it is. Once I’m outside I check it, if they watch out of the window they can see me doing it. Suppose it is so much that I’d stay counting for hours, it’s getting dark and I’m still there. They stay watching for a while once they’ve finished their work, but have to go home, I get that, sure, I could also go home and continue counting there. If it’s too little running back immediately won’t help, because nobody’s there anymore, and if I come back tomorrow I may have spent what’s missing tonight. Going somewhere where it’s warm enough to walk around without clothes during daytime, it helps me to know that something’s more there than here. For someone like me there’s work anywhere, it shouldn’t take a week to find work for me there. Three times work and a home close to work, I may choose one and try for a week whether I want to stay there. If at the end of the week I don’t want to stay I’m back on the next day, then it was a week’s holiday. RULES If that’s against a rule, it’s yet another one that I cannot observe, or only so briefly that I cannot re- member it later. Anyways the rules are only there to help me remember what I need in order to do better what I do. In that respect there’s no difference between the rules that I find in a book and the rules that I think of early in the morning. I know that because I’ve made a rule just now nothing has yet to observe it. CAUSE, SIGN A sign lets know what is going to happen, a cause lets it happen. If the sign also lets happen there is no reason to isolate it, because then I would isolate something only because it’s different for me. If I didn’t have to write this down myself, but would have secretaries to whom I could dictate it, I could to say more about it. If something is taken away from me I consider how it would be if the opposite had been taken from me. That is what causes or signifies what is farthest away from what is caused or signified by what has been taken away from me. note: For the translations of “The life of Kant, of Hegel” and “If I borrow enough money the bank becomes my slave” I was able to consult David Colmer’s wonderful translations.

In addition to its well‐known role as a coenzyme in oxidation–reduction reactions, the distinct role of NAD as a precursor for molecules involved in cell regulation has been clearly established. The involvement of NAD in these regulatory processes is based on its ability to function as a donor of ADP‐ribose; NAD synthesis is therefore required to avoid depletion of the intracellular pool. The rising interest in the biosynthetic routes leading to NAD formation and the highly conserved nature of the enzymes (...) involved prompted us to reconstruct the NAD biosynthetic routes operating in distinct eukaryotic organisms. The evidence obtained from biochemical and computational analysis provides a good example of how complex metabolic pathways may evolve. In particular, it is proposed that the development of several NAD biosynthetic routes during evolution has led to partial functional redundancy, allowing a given pathway to freely acquire novel functions unrelated to NAD biosynthesis.

Political liberals ask citizens not to appeal to certain considerations, including religious and philosophical convictions, in political deliberation. We argue that political liberals must include a demanding requirement of intellectual modesty in their ideal of citizenship in order to motivate this deliberative restraint. The requirement calls on each citizen to believe that the best reasoners disagree about the considerations that she is barred from appealing to. Along the way, we clarify how requirements of intellectual modesty relate to moral reasons for (...) deliberative restraint. And we argue against attempts to weaken our requirement of intellectual modesty by emphasizing those moral reasons. (shrink)

This paper provides a concise description and discussion of bottom–up and top–down approaches to misattribution of agency in schizophrenia. It explores if first-person accounts of passivity phenomena can provide support for one of these approaches. The focus is on excerpts in which the writers specifically examine their experiences of external influence. None of the accounts provides arguments that fit easily with only one of the possible approaches, which is in line with current attempts to theoretical integration.

Pour Proust, on le sait, la mémoire fouille dans les ruines ce que le Temps a détruit, et ce que l’Art peut parfois sublimer. Face à un traumatisme soudain et dévastateur, le passé récent “convertit” (dans le sens alchimique, religieux, hystérique du terme) sa banale quotidienneté pour s’investir après-coup en paradis à jamais perdu. (Or les paradis ne sont-ils pas toujours des paradis perdus –Milton, Proust, Freud, et al.)? Anticipant par une dizaine d’années le vécu de notre présent mondialement pandémique, (...) le film de Soderbergh met en scène la monstruosité inexorable du virus, avec le chaos, la dépression universelle et l’agressivité qui en résultent, – illustrant ainsi comment le quotidien se transforme en une invivable dystopie. Cependant /u-topie/ et /dys-topie/ s’entrelacent et se reconfigurent dans une dynamique dialectique : De même que le passé (rétrospectivement) utopique contenait déjà le code de sa propre auto-destruction, de même le présent (prospectivement) dystopique engendre endurance et lutte à mort pour sur-vivre, ne serait-ce que dans un mode d’être différent du passé perdu et du présent mortel. Ce faisant, comme le montre notre analyse, Soderbergh surprend par la dimension féministe de son film. (shrink)

We introduce the horizontal and vertical topologies on the product of topological spaces, and study their relationship with the standard product topology. We show that the modal logic of products of topological spaces with horizontal and vertical topologies is the fusion ${\bf S4}\oplus {\bf S4}$ . We axiomatize the modal logic of products of spaces with horizontal, vertical, and standard product topologies. We prove that both of these logics are complete for the product of rational numbers ${\Bbb Q}\times {\Bbb Q}$ (...) with the appropriate topologies. (shrink)

Inleiding in de wetenschapsfilosofie, bedoeld voor filosofiestudenten.

Isolated habitats, the consequence of the fragmentation process, are the object of external disturbance. This divides the patch area into two zones: interior and edge. The interior-to-edge ratio quantifies the potential disturbance impact. A method is presented to calculate a reference value for the interior-to-edge ratio, based upon the minimum edge for a given interior. The method is based on pixel geometry features and mathematical morphology. A corrected interior-to-edge ratio is defined using the reference value. The method is illustrated for (...) woodlot fragments in the Belgian Kempen region. (shrink)

An important factor in judging whether two retinal images arise from the same object viewed from different positions may be the presence of certain properties or cues that are 'qualitative invariants' with respect to the natural transformations, particularly affine transformations, associated with changes in viewpoint. To test whether observers use certain affine qualitative cues such as concavity, convexity, collinearity, and parallelism of the image elements, a 'same-different' discrimination experiment was carried out with planar patterns that were defined by four points (...) either connected by straight line segments (line patterns) or marked by dots (dot patterns). The first three points of each pattern were generated randomly; the fourth point fell on their diagonal bisector. According to the position of that point, the patterns were concave, triangular (three points being collinear), convex, or parallel sided. In a 'same' trial, an affine transformation was applied to one of two identical patterns; in a 'different' trial, the affine transformation was applied after the point lying on the diagonal bisector was perturbed a short, fixed distance along the bisector, inwards for one pattern and outwards for the other. Observers' ability to discriminate 'same' from 'different' pairs of patterns depended strongly on the position of the fourth, displaced, point: performance varied rapidly when the position of the displaced point was such that the patterns were nearly triangular or nearly parallel sided, consistent with observers using the hypothesised qualitative cues. The experimental data were fitted with a simple probabilistic model of discrimination performance that used a combination of these qualitative cues and a single quantitative cue. (shrink)

ABSTRACT:Although a research focus on the increasing involvement of corporations in shaping and maintaining the global rules of the game points out promising avenues for future research, it simultaneously makes clear how little currently established, mostly managerial conceptual frameworks have to offer in making sense of these developments. It is argued that we need to expand the rather restricted perspectives that these frameworks provide, in order to explore new conceptual foundations that will not only enable us to travel the confines (...) of the different disciplines involved with the study of the changing role of business in shaping the global rules of the game, but that can also systematically connect normative and positive research questions at the conceptual level. Three directions for this search for new foundations are briefly explored. (shrink)

Abstract:Work on stakeholder theory has proceeded on a variety of fronts; as Donaldson and Preston (1995) have noted, such work can be parsed into descriptive, instrumental, and normative research streams. In a normative vein, Phillips (1997) has made an argument for a principle of fairness as a means of identifying and adjudicating among stakeholders. In this essay, I propose that a reconstructed principle of fairness can be combined with the idea of consent as outlined in integrative social contract theory (ISCT) (...) to bring about a more normative stakeholder theory that also has ramifications for corporate governance.

While supporting the claim for culture in cetaceans, I suggest that Rendell and Whitehead's argument is potentially incomplete if based solely on ethnographic evidence. The notion of cetacean culture can also be explored experimentally. I hope to complement the authors' assertion by discussing dolphin brain and behavioural research findings, thus contributing to a more holistic argument for culture in dolphins.

Aim: To examine how physicians’ life stances affect their attitudes to end-of-life decisions and their actual end-of-life decision-making.Methods: Practising physicians from various specialties involved in the care of dying patients in Belgium, Denmark, The Netherlands, Sweden, Switzerland and Australia received structured questionnaires on end-of-life care, which included questions about their life stance. Response rates ranged from 53% in Australia to 68% in Denmark. General attitudes, intended behaviour with respect to two hypothetical patients, and actual behaviour were compared between all large (...) life-stance groups in each country.Results: Only small differences in life stance were found in all countries in general attitudes and intended and actual behaviour with regard to various end-of-life decisions. However, with regard to the administration of drugs explicitly intended to hasten the patient’s death , physicians with specific religious affiliations had significantly less accepting attitudes, and less willingness to perform it, than non-religious physicians. They had also actually performed PAD less often. However, in most countries, both Catholics and Protestants reported ever having made such a decision.Discussion: The results suggest that religious teachings influence to some extent end-of-life decision-making, but are certainly not blankly accepted by physicians, especially when dealing with real patients and circumstances. Physicians seem to embrace religious belief in a non-imperative way, allowing adaptation to particular situations. (shrink)

Palliative sedation is an option of last resort to control refractory suffering. In order to better understand palliative-care nurses’ attitudes to palliative sedation, an anonymous questionnaire was sent to all nurses (589) employed in palliative care in Flanders (Belgium). In all, 70.5% of the nurses (n = 415) responded. A large majority did not agree that euthanasia is preferable to palliative sedation, were against non-voluntary euthanasia in the case of a deeply and continuously sedated patient and considered it generally better (...) not to administer artificial floods or fluids to such a patient. Two clusters were found: 58.5% belonged to the cluster of advocates of deep and continuous sedation and 41.5% belonged to the cluster of nurses restricting the application of deep and continuous sedation. These differences notwithstanding, overall the attitudes of the nurses are in accordance with the practice and policy of palliative sedation in Flemish palliative-care units. (shrink)

Several important ethical dilemmas emerge when nurses join a public-sector strike. Such industrial action is commonplace in South Africa and was most notably illustrated by a national wage negotiation in 2010. Media coverage of the proceedings suggested unethical behaviour on the part of nurses, and further exploration is merited. Laws, policies and provisional codes are meant to guide nurses’ behaviour during industrial action, while ethical theories can be used to further illuminate the role of nurses in industrial action. There are, (...) however, important aspects to consider before judging whether nurses act unethically when striking. Following Loewy’s suggestion that the nature of the work, the proceeding commitment of the nurse to the patient, the prevailing situation when the strike is planned and the person(s) who stand(s) to benefit from the strike be considered, coupled with a consideration of the South African historical socio-political context, important aspects of the ethics of nurses’ behaviour in industrial action transpire.
