The central nervous system uses feedback processes that occur at multiple time scales to control interactions with the environment. The long-latency response is the fastest process that directly involves cortical areas, with a motoneuron response measurable 50 ms following an imposed limb displacement. Several behavioral factors concerning perturbation mechanics and the active role of muscles prior or during the perturbation can modulate the long-latency response amplitude in the upper limbs, but the interactions among many of these factors had not been (...) systematically studied before. We conducted a behavioral study on thirteen healthy individuals to determine the effect and interaction of four behavioral factors – background muscle torque, perturbation direction, perturbation velocity, and task instruction – on the LLRa evoked from the flexor carpi radialis and extensor carpi ulnaris muscles after velocity-controlled wrist displacements. The effects of the four factors were quantified using both a 0D statistical analysis on the average perturbation-evoked EMG signal in the period corresponding to an LLR, and using a timeseries analysis of EMG signals. All factors significantly modulated LLRa, and their combination nonlinearly contributed to modulating the LLRa. Specifically, all the three-way interaction terms that could be computed without including the interaction between instruction and velocity significantly modulated the LLR. Analysis of the three-way interaction terms of the 0D model indicated that for the ECU muscle, the LLRa evoked when subjects are asked to maintain their muscle activation in response to the perturbations was greater than the one observed when subjects yielded to the perturbations, but this effect was not measured for muscles undergoing shortening or in absence of background muscle activation. Moreover, higher perturbation velocity increased the LLRa evoked from the stretched muscle in presence of a background torque, but no effects of velocity were measured in absence of background torque. Also, our analysis identified significant modulations of LLRa in muscles shortened by the perturbation, including an interaction between torque and velocity, and an effect of both torque and velocity. The time-series analysis indicated the significance of additional transient effects in the LLR region for muscles undergoing shortening. (shrink)

Since Plato’s Republic, philosophers have outlined their expectations for political leaders and have offered judgments on the actions and decisions made by political leaders in their given context. It turns out that the American philosopher, William James, participates in this philosophical tradition. Although it has been assumed by professional philosophers—and even scholars of William James’s work—that James has no political philosophy, we argue that James’s political philosophy becomes both practical and useful for making judgments about and against political leaders.

This article begins with a review of studies in perception and depth psychology concerning the experience of exposure to sacred artworks in Roman Catholic and Eastern Orthodox contexts. This follows with the results of a qualitative inquiry involving 45 Roman Catholic, Eastern and Coptic Orthodox, and Protestant Christians in Canada. First, participants composed narratives detailing memories of spiritual experiences involving iconography. Then, in the context of a darkened room evocative of a sacred space, they viewed artworks depicting Biblical themes and (...) interpreted their meanings. Stimuli included “Western” paintings from the Roman tradition—a selection from the Gothic, Northern Renaissance, and Renaissance canon—and matched “Eastern” icons in the Byzantine style. Spiritual experience narratives were analyzed in terms of word frequencies, and interpretations of sacred artworks were analyzed thematically. Catholics tended to utilize emotional language when recalling their spiritual experiences, while religious activity was most often the concern of Protestants, and Orthodox Christians wrote most about spiritual figures and their signifiers. A taxonomy of response styles was developed to account for participants’ interpretations of Western and Eastern artworks, with content ranging from detached descriptions to projective engagement with the art-objects. Our approach allows for representation of diverse Christians’ interpretations of sacred art, taking into consideration personal, collective, and cultural-religious sources of meaning. Our paradigm also offers to enrich our understanding of the numinous or emotional dimension of mystical contact. (shrink)

The idea of the Internet as Gutenberg 2.0—a true revolution in disseminating information—is now a routine part of how bioethics education works. The Internet has become indispensable as a channel for sharing teaching materials and connecting learners with a central platform that houses materials to support an online or hybrid curriculum or a traditional course. A newer idea in bioethics education reflects developments in web-based medical education more broadly and draws on design principles developed for the Internet. This approach to (...) online bioethics education requires thinking about web-based learning as an engaging, potentially immersive experience, about learners' expectations concerning web-based learning, and about differences between self-directed learning and teaching to support group learning. In clinician education in bioethics, the interrelated goals of ethical reflection and practice for professionals and of continuous quality improvement in health care are supported by a focus on real-world challenges and by encouraging the habits of self-directed learning. In this paper, we describe how an international, interdisciplinary team used a web-based framework to develop a health care ethics casebook whose content, design, and pedagogy were tailored to the needs and expectations of health care professionals and other audiences in Singapore; we also explain how they used this framework to make the casebook accessible nationwide and to support cross-cultural learning.

A sample of 460 low-income women completed a mate preference questionnaire and surveys that assessed family background, life history, conscientiousness, sexual motives, self-ratings (e.g., looks), and current circumstances (e.g., income). A cluster analysis revealed two groups of women: women who reported a strong preference for looks and money in a short-term mate and commitment in a long-term mate, and women who reported smaller differences across mating context. Group differences were found in reported educational levels, family background, sexual development, number of (...) children, and motives for having sex. Implications for understanding individual differences in women’s mate-preference trade-offs are discussed. (shrink)

Hooglands commentaar op mijn ‘Pluralisme’ komt hierop neer dat levensbeschouwelijke neutraliteit niet mogelijk is, noch voor de overheid, noch voor de individuele burger. We kunnen geen radicale buitenstaanderspositie innemen tegenover de levensbeschouwing die we erop nahouden. Dat zou een vorm van hybris zijn. Wie niettemin levensbeschouwelijke neutraliteit bepleit en deze identificeert met tolerantie voor de levensbeschouwingen van anderen, pretendeert in feite dat het eigen tolerante standpunt moreel superieur is aan het standpunt van al diegenen die aan hun levensbeschouwing vastgeklonken zitten. (...) Dat is moreel verwerpelijk. (shrink)

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)

Everywhere in the world, and in every period of human history, it has been common for energy decisions to be made in an ethically haphazard manner. With growing population pressure and increasing demand for energy, this approach is no longer viable. We believe that decision makers must include ethical considerations in energy decisions more routinely and systematically. To this end, we propose an applied ethics framework that accommodates principles from three classical ethical theories—virtue ethics, deontology, consequentialism, and two Native American (...) ethics (Lakota and Navajo)—all considered from the perspectives of the impacted communities. We illustrate this framework by evaluating five recent energy decisions: the Dakota Access Pipeline, the Navajo Nation’s possible transition from coal to solar, hydraulic fracturing in Pennsylvania, uranium mining in Virginia, and the construction of the Xiaolangdi Dam in China. An applied ethics framework is preferable to existing ethical analyses because it can serve to sharpen arguments for (un)ethical decisions and action. Rather than treat ethical reasoning as a matter of opinion, we argue that applying ethical principles in a universal and standardized way adds rigor to energy sector decisions by presenting a position available for objective scrutiny. Because our framework identifies which aspects of a targeted action (if any) must adjust to improve ethical merit, it can serve as a practical tool for improving decision-making as we enter a new era of energy transitions.

In transfinite arithmetic 2n is defined as the cardinality of the family of all subsets of some set v with cardinality n. However, in the arithmetic of recursive equivalence types 2N is defined as the RET of the family of all finite subsets of some set v of nonnegative integers with RET N. Suppose v is a nonempty set. S is a class over v, if S consists of finite subsets of v and has v as its union. Such a (...) class is an intersecting class over v, if every two members of S have a nonempty intersection. An IC over v is called a maximal IC , if it is not properly included in any IC over v. It is known and readily proved that every MIC over a finite set v of cardinality n ≥ 1 has cardinality 2n-1. In order to generalize this result we introduce the notion of an ω-MIC over v. This is an effective analogue ot the notion of an MIC over v such that a class over a finite set v is an ω-MIC iff it is an MIC. We then prove that every ω-MIC over an isolated set v of RET N ≥ 1 has RET 2N-1. This is a generalization, for while there only are χ0 finite sets, there are ϰ isolated sets, where c denotes the cardinality of the continuum, namely all the finite sets and the c immune sets.

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)

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.

The fearful ape hypothesis proposes that heightened fearfulness in humans is adaptive. However, despite its attractive anthropocentric narrative, the evidence presented for greater fearfulness in humans versus other apes is not sufficient to support this claim. Conceptualization, context, and comparison are strongly lacking in Grossmann's proposal, but are key to understanding variation in the fear response among individuals and species.
