The U.S. stock market is one of the largest and most complex marketplaces in the global financial system. Over the past several decades, this market has evolved at multiple structural and temporal scales. New exchanges became active, and others stopped trading, regulations have been introduced and adapted, and technological innovations have pushed the pace of trading activity to blistering speeds. These developments have supported the growth of a rich machine-trading ecology that leads to qualitative differences in trading behavior at human (...) and machine time scales. We conduct a longitudinal analysis of comprehensive market data to quantify nonstationary dynamics throughout this system. We quantify the relationship between fluctuations in the number of active trading venues and realized opportunity costs experienced by market participants. We find that information asymmetries, in the form of quote dislocations, predict market-wide volatility indicators. Lastly, we uncover multiple micro-to-macro level pathways, including those exhibiting evidence of self-organized criticality. (shrink)

In spatial sequence synaesthesia ordinal stimuli are perceived as arranged in peripersonal space. Using fMRI, we examined the neural bases of SSS and colour synaesthesia for spoken words in a late-blind synaesthete, JF. He reported days of the week and months of the year as both coloured and spatially ordered in peripersonal space; parts of the days and festivities of the year were spatially ordered but uncoloured. Words that denote time-units and triggered no concurrents were used in a control condition. (...) Both conditions inducing SSS activated the occipito-parietal, infero-frontal and insular cortex. The colour area hOC4v was engaged when the synaesthetic experience included colour. These results confirm the continued recruitment of visual colour cortex in this late-blind synaesthetes. Synaesthesia also involved activation in inferior frontal cortex, which may be related to spatial memory and detection, and in the insula, which might contribute to audiovisual integration related to the processing of inducers and concurrents.

Recreational Drugs European Network (ReDNet) project aims to use the Psychonaut Web Mapping Project database (Psychonaut Web Mapping Group, 2009) containing novel psychoactive compounds usually not mentioned in the scientific literature and thus unknown to clinicians as a unique source of information. The database will be used to develop an integrated ICT prevention approach targeted at vulnerable individuals and focused on novel synthetic and herbal compounds and combinations. Particular care will be taken in keeping the health professionals working directly with (...) young people showing problematic behaviors regularly updated in terms of novel compounds and combinations as well. A user-friendly project website will be developed aimed primarily at delivering the information/prevention approaches, but will also be a way of communicating with project partners and relevant stakeholders (e.g. thematic forum facilities, instant messages, blogs, video chat, wikiblog, newsletters distributed via mailing list). The website will support various ICT prevention tools, including an SMS alert service. Different areas and sections will be aimed specifically at the different target groups. -/- . (shrink)

Duquesne University has already given us a number of works on the philosophy of nature, which is one of the most difficult and important parts of philosophy. Those of Van Melsen and Van Laer in particular will be recalled. The author of the present work, Fr. Koren, who became editor of Duquesne Studies in 1952, has already published a textbook on Metaphysics, reviewed in Vol. VII of Philosophical Studies, and another on the Philosophy of Man. He has in addition compiled (...) the excellent ‘Readings in the Philosophy of Nature’ which, as he says, constitutes a supplement to the work under review. (shrink)

After discussing the so-called Ham myth in South Africa, my focus is on the African church father Augustine (354–430). All texts from his immense oeuvre in which he mentions biblical Ham are reviewed in chronological order. In Against Faustus, the story of Noah and his sons is mainly explained as being Christological: Ham figures as a type of the unbelieving Jews who consented to the murder of Christ, but he is also a type of the Jews because he is ‘the (...) slave of his brothers’ carrying the books by which the Christians may be instructed. Later Augustine corrects his confusion of Ham with the slave Canaan. The story of Ham (and Canaan) is most extensively discussed in the City of God. Neither here nor in the Expositions on the Psalms, Ham is described as being black or a slave. The same goes for a number of his other writings. In Augustine’s late works Against Julian and Unfinished Work against Julian, he thoroughly goes into the question of why (although Ham sinned) ‘vengeance was brought upon Canaan’. Augustine perceives God’s prophecy: from Canaan stems the cursed seed [ semen maledictum ] of the Canaanites. Nowhere, however, he claims that Ham or his descendants would have been cursed to be black or that all of his offspring were condemned to slavery. Contribution: This article demonstrates that the Ham myth does not occur in Augustine. It argues that the ‘ mestizo ’ African Augustine might have been extra sensitive to questions of race and colour. (shrink)

This article aims to analyse all the passages in Augustine’s City of God in which he either explicitly or implicitly makes mention of Manichaeism and its doctrines. It turns out that, even in his later years, Manichaean doctrines were at the forefront of Augustine’s mind, although essential elements of his own doctrines have a clearly anti-Manichaean background. A close reading of all those anti-Manichaean passages further discloses some fairly unique particulars, such as, for example, the Manichaeans’ use and interpretation of (...) John 8:44 and 1 John 3:8. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Mimetic Theory and Its Rivals:A Reply to Pablo BanderaRichard van Oort (bio)There are three ways to respond to a rival theory. You can ignore it, you can assimilate it to what you already believe, or you can assess its merits independently and then either reject it or adopt it as the better, more powerful theory. Let us briefly review these three strategies.1. Assuming you are already in possession (...) of a sufficiently powerful theory, a safe bet is simply to ignore the newcomer. Contrary to appearances, this is not a totally unreasonable strategy. Time is in short supply. Those in possession of a theory adequate to their purposes will naturally be hesitant to investigate a new one, the understanding of which may require considerable investment in time and imaginative effort. Better to let others do the risky and quite possibly foolhardy work of inventing and elaborating new theories. Chances are their attempts will fail anyway. Truly original ideas are hard to come by and, given this fact, it only makes sense to stick with what works rather than waste time on unfamiliar and unproven ideas.2. The second response is, on the surface at least, more gracious and benevolent, but this benevolence masks an intransigence quite as dogmatic [End Page 189] as the first. Thus we welcome the new theory into the fold, but with a view to assimilating it to what we already know. The new theory is not our rival but our friend. Rather than emphasize the differences, we point to the theory's similarities with our existing framework. The new theory is said to improve our understanding of one or two details, but these are held to be merely minor modifications and not at odds with what we hold to be fundamentally true. Thus the new theory is not really new at all. It is but another disciple of the old. Its claim to a place at the table is not at the head, as a rival leader and master, but alongside the other disciples whose collective task it is to disseminate the teachings of the one true master. This strategy is in fact extremely common and entirely understandable, from the viewpoint of both the adherents of the old theory and those of the new. For while the adherents of the old theory receive further confirmation of the superiority of their way of looking at the world, the adherents of the new theory receive a measure of respect by gaining access to an existing center of attention. As we all know, the mimetic attention space is by definition limited. We can't focus on everything at once, and sometimes the best strategy for a new theory is, so to speak, to follow the money. One piggybacks on the existing centers of attention. But the drawback is that the more one piggybacks, the less "new" one becomes.3. The third and final response is to take the new theory seriously as a rival center of attention. But this forces us into a genuine dilemma. For now we have to choose between theories that are accepted, for the time being at least, as equals in terms of their rivalry for our attention. But if both claim to be equally foundational, equally deserving of our attention to first things, then both cannot be equally true. One theory must come first; one must be superior to the other. But which?In a recent issue of Contagion, Pablo Bandera urges Girardians to adopt the third strategy when assessing Eric Gans's generative anthropology.1 We must recognize the theory's status as a genuine rival. Bandera believes that once the assessment has been fairly made, we must end up rejecting Gans's theory, at least insofar as it purports to be a theory of mimetic desire. The trouble is, Bandera claims, that most Girardians have adopted the second strategy, that is, they have simply assimilated Gans as a (slightly modified) version of Girard, without bothering to notice the very real differences between the two. The first strategy, complete ignorance of Gans's work, Bandera believes to be inaccurate as a description of the current situation. Indeed, he goes so... (shrink)

John Calvin (1509–1564) started his career as a thoroughly trained humanist who possessed, in addition, a thorough knowledge of the Fathers of the Church. This article provides an overview of this particular knowledge. It also focuses on the use Calvin made of the patristic argument in both his instructive and apologetic writings. Some evident cases of Calvin’s misuse of the patres are discussed as well. It is concluded that Calvin’s special patristic knowledge gave his theology its special hallmark and still (...) links authentic Calvinism with the church’s catholic tradition through the ages.

This article offers an account of at least some of the non-preparatory dimensions of education and their significance for a theory of educational justice. I argue that just schools should play a role in facilitating goods of childhood. I also defend an egalitarian view about the access children should have in school to the resources and opportunities associated with the non-preparatory dimensions of education.

have recently provided a compelling demonstration of enhanced attentional control under post-hypnotic suggestion. Using the classic color-word interference paradigm, in which the task is to ignore a word and to name the color in which it is printed (e.g., RED in green, say ''green''), they gave a post-hypnotic instruction to participants that they would be unable to read. This eliminated Stroop interference in high suggestibility participants but did not alter interference in low suggestibility participants. replicated this pattern and further demonstrated (...) that it is not due to a visual strategy (such as blurring or looking at a different location). As a historical footnote, we describe a ''case study'' from 18 years ago in which we observed the same result using a hypnotic instruction to a single highly suggestible individual that he could not read. The elimination of Stroop interference has important implications for both the study of attention and the study of hypnosis. (shrink)

This paper provides a critical commentary on the claim advanced by Harry Brighouse and Adam Swift in their book Family Values: The Ethics of Parent–Child Relationships that there is an ineliminable conflict between relationship goods and fair equality of opportunity. I argue there need be no conflict between family values and equality of opportunity in a suitably non-hierarchical society. I also argue that the idea that equality of opportunity might be served by abolishing the family is mistaken. Egalitarian justice does (...) not provide an obstacle to the realization of family values. (shrink)

Three experiments investigated two timed implicit tests of memory—word reading and color naming. Using the study–test procedure, Experiments 1 and 2 showed that studied words caused reliable facilitation in word reading but no interference in color naming relative to unstudied words. Indeed, there was a small amount of facilitation in color naming as well. Experiment 3 further explored the color naming task by alternating shorter study and test intervals and adding control trials consisting of letter strings. Although both studied and (...) unstudied words showed interference relative to the control letter strings, the amounts of interference they showed did not differ. Overall, word reading consistently displayed facilitation whereas color naming never exhibited increased interference due to word priming. Priming appears to be process-specific: It is restricted to facilitating repetition of processing previously applied to a stimulus and does not extend to influencing performance on a different task involving the same studied materials.

Introduction Biobank-based research is growing in importance. A major controversy exists about the return of aggregate and individual research results. Methods The authors used a mixed-method approach in order to study parents' attitudes towards the return of research results regarding themselves and their children. Participants attended four 2-h, deliberative-engagement sessions held on two consecutive Saturdays. Each session consisted of an educational presentation followed by focus-group discussions with structured questions and prompts. This manuscript examines discussions from the second Saturday which focused (...) on the benefits and risks of returning aggregate and individual research results regarding both adults (morning session) and children (afternoon session). Attitudes were assessed in pre-engagement and post-engagement surveys. Results The authors recruited 45 African-American adults whose children received medical care at two healthcare facilities on the South Side of Chicago that serve different socioeconomic communities. Three dominant themes were identified. First, most participants stated that they would enrol themselves and their children in a biobank, although there was a vocal minority opposed to enrolling children, particularly children unable to participate in the consent process. Second, participants did not distinguish between the results they wanted to receive regarding themselves and their children. Supplemental survey data found no attitudinal changes pre-engagement and post-engagement. Third, participants believed that children should be allowed access to their health information, but they wanted to be involved in deciding when and how the information was shared. Discussion Participant attitudes are in tension with current biobank policies. An intensive educational effort had no effect on their attitudes. (shrink)

Cet article propose une réponse critique à quelques thèmes du livre de Kyle Johannsen,A Conceptual Investigation of Justice. La discussion se penche sur l’analyse du pluralisme fondamental de la valeur proposée par Johannsen et met en cause cette même analyse. Je soutiens que l’analyse proposée par Johannsen ne parvient pas à expliquer comment des conflits entre des valeurs fondamentales peuvent être résolus et qu’il y a davantage de convergence entre des valeurs fondamentales que ne le reconnaît Johannsen.

We have previously built a small IKg ([Angle 89] and [Brooks 89]) six legged walking robot named Genghis. It was remarkably successful as a testbed to develop walking and learning algorithms. It encouraged us to build a more fully engineered robot with higher performance. We are building two copies of the robot, both 1.6Kg in mass. Their generic name is Attila. Attila has 24 actuators and over 150 sensors, all connected via a local network (the I2C bus) to 11 onboard (...) computers. (shrink)

The earliest Christians – all of whom were Jews – spoke of the Holy Spirit as a feminine figure. The present article discusses the main proof texts, ranging from the ‘Gospel according to the Hebrews’ to a number of testimonies from the second century. The ancient tradition was, in particular, kept alive in East and West Syria, up to and including the fourth century Makarios and/or Symeon, who even influenced ‘modern’ Protestants such as John Wesley and the Moravian leader Count (...) von Zinzendorf. It is concluded that, in the image of the Holy Spirit as woman and mother, one may attain a better appreciation of the fullness of the Divine. (shrink)

This paper explores tensions in Ronald Dworkin's liberal theory (and liberalism more generally) about the appropriate relationship of the state to the different conceptions of the good that may be adopted by its citizens. Liberal theory generally supposes that the state must exhibit a kind of impartiality to different conceptions of the good. This impartiality is often thought to be captured by an anti-perfectionist ideal of liberal neutrality. But neutrality is often criticized as an ideal that lacks adequate theoretical support (...) and is difficult to reconcile with liberalism's commitment to government support of various elements of a community's culture. Nonetheless, Dworkin has tried to explain systematically how his egalitarian brand of liberalism can explain the appropriateness of a particular variety of neutrality. I argue, however, that Dworkin's account of the relationship between liberalism and the good is ambiguous. I suggest that an ideal of tolerance which embraces a mild form of perfectionism fits better with the egalitarian foundations of Dworkin's liberalism than neutrality. Moreover, tolerance is an ideal through which familiar tensions about the liberal state's relationship to the good may be resolved. (shrink)

This chapter begins with an overview of John Rawls's four‐stage sequence account of how to apply justice as fairness to institutions. It focuses on the facets of institutional design: (i) How should basic democratic institutions and processes be structured so as to realize the fair value of the basic political liberties? (ii) What kinds of educational and health institutions are needed to secure fair equality of opportunity? (iii) How do principles of justice apply to the family? (iv) What implications does (...) the difference principle have for the structure of a market economy? Rawls's extension of the original position via the four‐stage sequence proceeds against the background of three kinds of pluralism. According to Rawls, occupational choice means that there is a diversity of positions open to all citizens, and no one is forced to hold or pursue specific kinds of employment. (shrink)

Can suggestion, particularly hypnotic suggestion, influence cognition? Addressing this intriguing question experimentally is on the rise in cognitive research, nowhere more prevalently than in the domain of cognitive control and attention. This may well rest on the intuitive connection between hypnotic suggestion and attention, where the hypnotist controls the subject’s attention. Particularly impressive has been the work of Raz and his colleagues demonstrating the modulation and even the complete elimination of classic Stroop color–word interference when subjects are given a posthypnotic (...) suggestion that words are meaningless. Overriding a highly practiced, possibly even automatic response like reading is testament to the attentional control that can be exerted under hypnotic suggestion. What else do we need to know—in the Stroop context and more broadly—to obtain a clear picture of how suggestion can orchestrate attention? (shrink)
