The parasol, whatever the conditions of use, ultimately functions as a social symbol as it satisfies no utilitarian need. The operative mechanism of that symbol varies from culture to culture but the parasol is polysemous even at its least complicated, when held by the person to be protected without allusion to foreign social systems and in the context of single-sex usage. For example, as an implement of fashionable feminine attire of over a century ago, the parasol signified the maintenance of (...) a standard of beauty that precluded extended activities out of doors and the delicate constitution of the lady thus protected, both with further implications of ‘good breeding’ and economic inutility; and the wasteful employment of items that must be changed with the costume and discarded before unserviceable to suit the dictates of fashion. Both facets—termed ‘conspicuous leisure’ and ‘conspicuous consumption’ by Veblen—conjointly served to advertise the wealth of the individual man on the basis of whose property such extravagance and non-productive practice could be sustained.

Brain–computer interfaces are a form of technology that read a user’s neural signals to perform a task, often with the aim of inferring user intention. They demonstrate potential in a wide range of clinical, commercial, and personal applications. But BCIs are not always simple to operate, and even with training some BCI users do not operate their systems as intended. Many researchers have described this phenomenon as “BCI illiteracy,” and a body of research has emerged aiming to characterize, predict, and (...) solve this perceived problem. However, BCI illiteracy is an inadequate concept for explaining difficulty that users face in operating BCI systems. BCI illiteracy is a methodologically weak concept; furthermore, it relies on the flawed assumption that BCI users possess physiological or functional traits that prevent proficient performance during BCI use. Alternative concepts to BCI illiteracy may offer better outcomes for prospective users and may avoid the conceptual pitfalls that BCI illiteracy brings to the BCI research process. (shrink)

The Radical Enlightenment has been much discussed and its original meaning somewhat distorted. In 1981 my concept of the storm that unleashed a new, transnational intellectual movement possessed a strong contextual and political element that I believed, and still believe, to be critically important. Idealist accounts of enlightened ideas that divorce them from politics leave out the lived quality of the new radicalism born in reaction to monarchical and clerical absolutism. Taking the religious impulse seriously and working to defang it (...) of bellicosity would require years of labor. First all the world’s religions had to be surveyed, see Picart’s seven folio volumes; and Rousseau’s Savoyard vicar had to both preach and live religion simply as true virtue; and finally Jefferson editing the Bible so as to get the irrational parts simply removed, thus making people more fit to grant a complete religious toleration. Throughout the century all these approaches to revealed religion may be legitimately described as radical. Each produced a different recommendation for its replacement. As I have now come to see, the pantheism I identified in 1981 would lead in many directions, among them lay the search to understand all human religiosity and to articulate a universal natural religion.

Previous research has shown that angry and happy faces are perceived as less emotionally intense when shown with averted versus direct gaze. Other work reports that long-term memory for angry faces was poorer when they were encoded with averted versus direct gaze, suggesting that threat signals are diluted when eye contact is not engaged. The current study examined whether gaze modulates working memory for angry and happy faces. In stark contrast to LTM effects, WM for angry faces was not significantly (...) modulated by gaze direction. However, WM for happy faces was significantly enhanced when gaze was averted versus direct. These findings suggest that in WM – when rapid processing and an immediate response is required – averted gaze may alter the meaning behind a smile, and make this kind of expression particularly salient for short-term processing.

A major new history of how the Enlightenment transformed people’s everyday lives The Secular Enlightenment is a panoramic account of the radical ways that life began to change for ordinary people in the age of Locke, Voltaire, and Rousseau. In this landmark book, familiar Enlightenment figures share places with voices that have remained largely unheard until now, from freethinkers and freemasons to French materialists, anticlerical Catholics, pantheists, pornographers, readers, and travelers. Margaret Jacob, one of our most esteemed historians of (...) the Enlightenment, reveals how this newly secular outlook was not a wholesale rejection of Christianity but rather a new mental space in which to encounter the world on its own terms. She takes readers from London and Amsterdam to Berlin, Vienna, Turin, and Naples, drawing on rare archival materials to show how ideas central to the emergence of secular democracy touched all facets of daily life. Human frailties once attributed to sin were now viewed through the lens of the newly conceived social sciences. People entered churches not to pray but to admire the architecture, and spent their Sunday mornings reading a newspaper or even a risqué book. The secular-minded pursued their own temporal and commercial well-being without concern for the life hereafter, regarding their successes as the rewards for their actions, their failures as the result of blind economic forces. A majestic work of intellectual and cultural history, The Secular Enlightenment demonstrates how secular values and pursuits took hold of eighteenth-century Europe, spilled into the American colonies, and left their lasting imprint on the Western world for generations to come.

From 1687, the year when Newton published his Principia, to the Crystal Palace Exhibition of 1851, science gradually became central to Western thought and economic development. The book examines how, despite powerful opposition on the Continent, a Newtonian understanding gained acceptance and practical application.

As more and more historians acknowledge the central signifcance of science and technology with that of modern society, the need for a good, general history of the achievements of the Scientific Revolution has grown. Scientific Culture and The Making of the Industrial West seeks to explain this historical process by looking at how and why scientific knowledge became such an integral part of the culture of Europe in the seventeenth and eighteenth centuries, and how this in turn lead to the (...) Industrial Revolution. This comparative study not only looks at England, and its success, but follows through with the history of France, the Netherlands, and Germany. (shrink)

Using payment to recruit research subjects is a common practice, but it raises ethical concerns that coercion or undue inducement could potentially compromise participants’ informed consent. This is the first national study to explore the attitudes of IRB members and other human subjects protection professionals concerning whether payment of research participants constitutes coercion or undue influence, and if so, why. The majority of respondents expressed concern that payment of any amount might influence a participant’s decisions or behaviors regarding research participation. (...) Respondents expressed greater acceptance of payment as reimbursement or compensation than as an incentive to participate in research, and most agreed that subjects are coerced if the offer of payment makes them participate when they otherwise would not or when the offer of payment causes them to feel that they have no reasonable alternative but to participate . Views about undue influence were similar. We conclude that human subjects protection professionals hold expansive and inconsistent views about coercion and undue influence that may interfere with the recruitment of research participants and impede valuable research.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.2 (2003) 276-277 [Access article in PDF] Wiep Van Bunge. From Stevin to Spinoza: An Essay on Philosophy in the Seventeenth-Century Dutch Republic. Leiden: Brill, 2001. Pp. xii + 217. Cloth, $80.00 By 1660 there were probably more followers of Descartes in the Dutch Republic, population 1.4 million, than in France, population 20 million. Protestantism and prosperity encouraged high rates of literacy and (...) the universities of Leiden and Utrecht were among the liveliest in the world. This vibrancy infused the metaphors that Descartes put into his great Discours de la methode published first in Leiden in 1637. In it he spoke about the beauty of cities that looked as if they had been built by a single architect and of the freedom to be found among people so busy with their business as to leave thinkers to their pursuits. Indirectly he spoke about his adopted homeland where he found many followers—some more eager than loyal. By the 1640s disputes raged in the Republic and the anti-Cartesian forces were led by the Aristotelian and anti-Copernican Gisbertus Voetius. What has been missing in our scholarship up to now has been any convincing account as to why these disputes occurred, and how they resonated within the Dutch context. Wiep Van Bunge's book takes a big step toward closing that knowledge gap.Van Bunge convincingly argues that the vibrancy of the stadtholder-less period up to 1672 produced a willingness to entertain new ideas. It also did not hurt to have Descartes on the scene and active on behalf of his mechanical philosophy, even to the point of addressing the Utrecht magistrates publicly and asking that his critics be chastised. What is remarkable—especially given the resistance to Descartes seen at Oxford and Cambridge—was the speed with which Cartesian ideas entered the Dutch classrooms where as many as a third of the students came from abroad. Again Van Bunge provides context when he starts with the Dutch engineer Simon Stevin and demonstrates the vitality of mathematics for a commercial society but also for a militant one. (The Netherlands was at war with Spain up to 1609.) A recent exhibition at the J. Paul Getty Museum in Los Angeles, April to July 2002, also illustrates another aspect of mathematics in the Republic. Precisely in the 1630s when Descartes was putting the finishing touches on his Discours, Pieter Saenredam applied geometry to the interiors of the elegant Utrecht churches so as to give his paintings a regularity and precision worthy of the Cartesian dream of order and clarity. The Dutch commitment to discipline and order also made their army one of the most accomplished in the world. It was perhaps over-determined that Descartes, who had trained with it, would find such a sympathetic audience in the Republic.One of the more fascinating aspects of Van Bunge's detailed study, first of Cartesianism and then of Spinozism in the Republic, concerns the political and ideological meanings to be extracted from the new philosophy. Hobbes also finds a place in the narrative, surprisingly taken up by republicans eager to construct a state that could control the passions. Abraham van Berkel, who put Hobbes's Leviathan into Dutch in 1667, gave the allegiance of his text and himself to Jan de Witt and the cause of the regents and the estates. We can only wonder what Hobbes would have made of the association. The republican affiliations of the mechanical philosophy in the Republic provide a distinctively Dutch context to the [End Page 276] political writings of Spinoza, the most famous and outrageous Cartesian of the century. Van Bunge is especially deft in finding Spinozists and providing far more evidence than I could back in 1981 when I argued for a radical enlightenment within the late seventeenth-century Dutch context (see The Radical Enlightenment. Pantheists, Freemasons and Republicans [London: 1981]). None of these positions with their deeply heretical implications could be taken lightly or without danger. Men lost... (shrink)

The Natuurkundig Genootschap der Dames , formally established by and for women, met regularly from 1785 to 1881 and sporadically until 1887. It challenges our stereotypes both of women and the physical sciences during the eighteenth century and of the intellectual interests open to women in the early European republics. This essay aims not simply to identify the society and its members but to describe their pursuits and consider what their story adds to the history of Western science. What does (...) this society’s existence tell us about the relationship between women and early science in general and about science and society in the Dutch setting in particular? Science and gender look rather different when observed through the activities of the immensely prosperous women of Middelburg, citizens of one of the most highly literate Western countries. The elite lives of the first‐generation members of the women’s society also offer us a glimpse into the early domestication of science, a process vital to its acceptance and assimilation. (shrink)

This book addresses one of the most urgent questions in American society today, one that is currently in the spotlight and hotly debated on all sides: Who shall rule the schools--parents or educators? _School Choice or Best Systems: What Improves Education?_ presents an overview of research and practical applications of innovative--even radical--school reforms being implemented across the United States. These fall along a continuum ranging from "parental choice" to "best systems." At the one extreme are schools of choice, which allow (...) parents to choose and even govern schools for their children. These include charter schools, traditional private and parochial schools, schools that are privately governed but publicly funded through vouchers, and those that are funded by private scholarships provided by both corporations and wealthy individuals. At the other extreme are centralized state or district systems, based on reform initiatives and new systems of education that have been developed in response to views of citizens and legislators that schools can do much better. These schools, which specify uniform goals, policies, and programs for each school, are highly innovative systems based on research or representing advanced thinking about "what works," and have attracted wide interest. Important questions related to schools of choice and best systems are addressed: How can we choose among schools of choice and best systems? Among the various approaches within each of these alternatives? How can we understand their guiding principles and operational practices? What results do they produce? How can we evaluate their claims? In choosing among the alternatives, how should issues of student achievement, accountability, costs, feasibility, and equity be factored in? This volume brings together leading researchers and education leaders who have carried out the latest studies and advances in the field, providing a forum for them to set forth the arguments and evidence that will be most helpful in making choices for tomorrow's schools. It does not provide a single "right" answer--values and preferences differ across parents, schools, districts, and states. However, there are benefits for all from seeing the rigorous research, challenging thinking, and alternate points of view this volume presents. (shrink)

This response (a) integrates non-equilibrium evolutionary genetic models, such as coevolutionary arms-races and recent selective sweeps, into a framework for understanding common, harmful, heritable mental disorders; (b) discusses the forms of ancestral neutrality or balancing selection that may explain some portion of mental disorder risk; and (c) emphasizes that normally functioning psychological adaptations work against a backdrop of mutational and environmental noise. (Published Online November 9 2006).

Given that natural selection is so powerful at optimizing complex adaptations, why does it seem unable to eliminate genes (susceptibility alleles) that predispose to common, harmful, heritable mental disorders, such as schizophrenia or bipolar disorder? We assess three leading explanations for this apparent paradox from evolutionary genetic theory: (1) ancestral neutrality (susceptibility alleles were not harmful among ancestors), (2) balancing selection (susceptibility alleles sometimes increased fitness), and (3) polygenic mutation-selection balance (mental disorders reflect the inevitable mutational load on the thousands (...) of genes underlying human behavior). The first two explanations are commonly assumed in psychiatric genetics and Darwinian psychiatry, while mutation-selection has often been discounted. All three models can explain persistent genetic variance in some traits under some conditions, but the first two have serious problems in explaining human mental disorders. Ancestral neutrality fails to explain low mental disorder frequencies and requires implausibly small selection coefficients against mental disorders given the data on the reproductive costs and impairment of mental disorders. Balancing selection (including spatio-temporal variation in selection, heterozygote advantage, antagonistic pleiotropy, and frequency-dependent selection) tends to favor environmentally contingent adaptations (which would show no heritability) or high-frequency alleles (which psychiatric genetics would have already found). Only polygenic mutation-selection balance seems consistent with the data on mental disorder prevalence rates, fitness costs, the likely rarity of susceptibility alleles, and the increased risks of mental disorders with brain trauma, inbreeding, and paternal age. This evolutionary genetic framework for mental disorders has wide-ranging implications for psychology, psychiatry, behavior genetics, molecular genetics, and evolutionary approaches to studying human behavior.

Deception is a useful methodological device for studying attitudes and behavior, but deceptive studies fail to fulfill the informed consent requirements in the U.S. federal regulations. This means that before they can be approved by Institutional Review Boards, they must satisfy the four regulatory conditions for a waiver or alteration of these requirements. To illustrate our interpretation, we apply the conditions to a recent study that used deception to show that subjects judged the same wine as more enjoyable when they (...) believed it had a higher price.

The hippocampal formation is a structure critical to navigation and many forms of memory. In mammals, the firing of place cells is widely regarded as the fundamental unit of HF information processing. Supporting homology between the avian and mammalian HF, context-specific patterns of Egr1 have been reported in birds that are comparable to those produced by place cell firing in mammals. Recent electrophysiological data, however, suggest that many avian species lack place cells, potentially undermining the correspondence between Egr1 and place (...) cell-related firing in the avian brain. To clarify this, the current study examines Egr1 expression in Japanese quail under conditions known to elicit only weakly spatially modulated firing patterns and report robust context-dependent Egr1 expression. These data confirm that context-dependent expression of Egr1 is not dependent on precise place fields and provide insight into how these birds are able to perform complex spatial tasks despite lacking mammalian-like place cells.

Mood disorders, including major depressive disorder and bipolar disorder, are highly prevalent, frequently disabling, and sometimes deadly. Additional research and more effective medications are desperately needed, but clinical trials research in mood disorders is fraught with ethical issues. Although many authors have discussed these issues, most do so from a theoretical viewpoint. This manuscript uses available empirical data to inform a discussion of the primary ethical issues raised in mood disorders research. These include issues of consent and decision-making capacity, including (...) patients’ motivations for participating in research. We also address drug withdrawals, placebo controls, and the overall safety of research. Finally, we examine the extant literature for studies discussing potential indirect benefits of clinical trials research to participants. Taken together, the evidence suggests that clinical trials research incorporating drug withdrawals and placebo controls can be conducted safely and ethically, even in patients with severe or treatment-resistant mood disorders. In fact, given the dearth of effective treatment options for this population, it is our opinion that a moral imperative exists to extend the offer of research participation to severely ill or treatment-resistant groups.
