In theorizing the postmodern, one inevitably encounters the postmodern assault on theory, such as Lyotard's and Foucault's attack on modern theory for its alleged totalizing and essentializing character. The argument is ironic, of course, since it falsely homogenizes a heterogeneous "modern tradition" and since postmodern theorists like Foucault and Baudrillard are often as totalizing as any modern thinker (Kellner 1989 and Best 1995). But where Lyotard seeks justification of theory within localized language games, arguing that no universal criteria are possible (...) to ground objective truths or universal values, Foucault steadfastly resists any efforts, local or otherwise, to validate normative concepts and theoretical perspectives. For Foucault, justification ensnares one in metaphysical illusions like "truth" and the only concern of the philosopher-critic is to dismantle old ways of thinking, to attack existing traditions and institutions, and to open up new horizons of experience for greater individual freedom. What matters, then, is results, and if actions bring greater freedom, the theoretical perspectives informing them are "justified." From this perspective, theoretical discourse is seen not so much as "correct" or true," but as "efficacious," as producing positive effects. (shrink)

The finding that women are attracted to men older than themselves whereas men are attracted to relatively younger women has been explained by social psychologists in terms of economic exchange rooted in traditional sex-role norms. An alternative evolutionary model suggests that males and females follow different reproductive strategies, and predicts a more complex relationship between gender and age preferences. In particular, males' preferences for relatively younger females should be minimal during early mating years, but should become more pronounced as the (...) male gets older. Young females are expected to prefer somewhat older males during their early years and to change less as they age. We briefly review relevant theory and present results of six studies testing this prediction. Study 1 finds support for this gender-differentiated prediction in age preferences expressed in personal advertisements. Study 2 supports the prediction with marriage statistics from two U.S. cities. Study 3 examines the cross-generational robustness of the phenomenon, and finds the same pattern in marriage statistics from 1923. Study 4 replicates Study 1 using matrimonial advertisements from two European countries, and from India. Study 5 finds a consistent pattern in marriages recorded from 1913 through 1939 on a small island in the Philippines. Study 6 reveals the same pattern in singles advertisements placed by financially successful American women and men. We consider the limitations of previous normative and evolutionary explanations of age preferences and discuss the advantages of expanding previous models to include the life history perspective.

This collection of thirteen original essays by such well-known philosophers as Thomas Nagel, Peter Singer, J.O. Urmson, David A.J. Richards, James Griffin, R.B. Brandt, John C. Harsanyi, T.M. Scanlon, and others discusses the philosophy of R.M. Hare put forth in his book Moral Thinking, including his thoughts on universalizability, moral psychology, and the role of common-sense moral principles. In addition, Professor Hare responds to his critics with an essay and a detailed, point-by-point criticism.

Cenzer, D., R. Downey, C. Jockusch and R.A. Shore, Countable thin Π01 classes, Annals of Pure and Applied Logic 59 79–139. A Π01 class P {0, 1}ω is thin if every Π01 subclass of P is the intersection of P with some clopen set. Countable thin Π01 classes are constructed having arbitrary recursive Cantor- Bendixson rank. A thin Π01 class P is constructed with a unique nonisolated point A and furthermore A is of degree 0’. It is shown that no (...) set of degree ≥0” can be a member of any thin Π01 class. An r.e. degree d is constructed such that no set of degree d can be a member of any thin Π01 class. It is also shown that between any two distinct comparable r.e. degrees, there is a degree that contains a set which is of rank one in some thin Π01 class. It is shown that no maximal set can have rank one in any Π01 class, while there exist maximal sets of rank 2. The connection between Π01 classes, propositional theories and recursive Boolean algebras is explored, producing several corollaries to the results on Π01 classes. For example, call a recursive Boolean algebra thin if it has no proper nonprincipal recursive ideals. Then no thin recursive Boolean algebra can have a maximal ideal of degree ≥0”. (shrink)

Proceedings from the ninth International Conference on Artificial Life; papers by scientists of many disciplines focusing on the principles of organization and applications of complex, life-like systems. Artificial Life is an interdisciplinary effort to investigate the fundamental properties of living systems through the simulation and synthesis of life-like processes. The young field brings a powerful set of tools to the study of how high-level behavior can arise in systems governed by simple rules of interaction. Some of the fundamental questions include: (...) What are the principles of evolution, learning, and growth that can be understood well enough to simulate as an information process? Can robots be built faster and more cheaply by mimicking biology than by the product design process used for automobiles and airplanes? How can we unify theories from dynamical systems, game theory, evolution, computing, geophysics, and cognition? The field has contributed fundamentally to our understanding of life itself through computer models, and has led to novel solutions to complex real-world problems across high technology and human society. This elite biennial meeting has grown from a small workshop in Santa Fe to a major international conference. This ninth volume of the proceedings of the international A-life conference reflects the growing quality and impact of this interdisciplinary scientific community. (shrink)

Glowacki's account overlooks the role of religion in the regulation of cooperation, tolerance, and peace values. We interrogate three premises of Glowacki's argument and suggest that approaching religion as an adaptive system reveals how religious commitments and practices likely had a more substantial impact on the evolution of peace and conflict than currently presumed.

Dehumanization is routinely invoked in social science and law as the primary factor in explaining how propaganda encourages support for, or participation in, violence against targeted outgroups. Yet the primacy of dehumanization is increasingly challenged by the apparent influence of revenge on collective violence. This study examines critically how various propaganda influence audiences. Although previous research stresses the dangers of dehumanizing propaganda, a recently published study found that only revenge propaganda significantly lowered outgroup empathy. Given the importance of these findings (...) for law and the behavioral sciences, this research augments that recent study with two additional samples that were culturally distinct from the prior findings, showing again that only revenge propaganda was significant. To explore this effect further, we also conducted a facial electromyography (fEMG) among a small set of participants, finding that revenge triggered significantly stronger negative emotions against outgroups than dehumanization.

We argue that limiting the theory of extreme self-sacrifice to two determinants, namely, identity fusion and group threats, results in logical and conceptual difficulties. To strengthen Whitehouse's theory, we encourage a more holistic approach. In particular, we suggest that the theory include exogenous sociopolitical factors and constituents of the religious system as additional predictors of extreme self-sacrifice.

What is the relationship between war propaganda and nationalism, and what are the effects of each on support for, or participation in, violent acts? This is an important question for international criminal law and ongoing speech crime trials, where prosecutors and judges continue to assert that there is a clear causal link between war propaganda, nationalism, and mass violence. Although most legal judgments hinge on the criminal intent of propagandists, the question of whether and to what extent propaganda and nationalism (...) interact to cause support for violence or participation remains unanswered. Our goal here is to contribute to research on propaganda and nationalism by bridging international criminal law and the behavioral and brain sciences. We develop an experiment conducted with Serbian participants that examines the effects of propaganda as identified in the latest international speech crime trial as causing mass violence, and thereby test hypotheses of expert witness Anthony Oberschall’s theory of mass manipulation. Using principal components analysis and Bayesian regression, we examine the effects of propaganda exposure and prior levels of nationalism as well as other demographics on support for violence, ingroup empathy, and outgroup empathy. Results show that while exposure to war propaganda does not increase justifications of violence, specific types of war propaganda increase ingroup empathy and decrease outgroup empathy. Further, although nationalism by itself is not significant for justifying violence, the interaction of increased nationalism and exposure to violent media is significant for altering group empathies. The implications of these findings are discussed with respect to international criminal law and the cognitive science of nationalism. (shrink)

During the past decade, Medicaid has experienced extraordinary growth, in both number of beneficiaries and total expenditures. Between 1988 and 1993, the number of Medicaid beneficiaries grew from 22 million to 32 million. While the number of Medicaid beneficiaries increased by 45 percent, expenditures increased by 145 percent, from 51 billion to 125 billion. Expressed in terms of its percentage of state budgets, Medicaid doubled from 10 percent to 20 percent over the same time period, to the point that it (...) is currently the second largest budget item for most states.Faced with unsustainable rates of program budget growth and serious concerns about the level of access and the continuity of care afforded by the Medicaid program, states have turned to managed care. Almost every state has introduced some form of managed care for a subset of their Medicaid beneficiary population. Twenty-three states have gone farther, and implemented, proposed, or are developing section 1115 waivers to overhaul their Medicaid programs. These waivers allow states to develop and introduce nonstandard approaches to benefits, eligibility, service delivery, and financing for the Medicaid beneficiary population. (shrink)

This collection of essays aims to mark a place for American philosophy as it moves into the twenty-first century. Taking their cue from the work of Peirce, James, Santayana, Dewey, Mead, Buchler, and others, the contributors assess and employ philosophy as an activity taking place within experience and culture. Within the broad background of the American tradition, the essays reveal a variety of approaches to the transition in which American philosophy is currently engaged. Some of the pieces argue from an (...) historical dialogue with the tradition, some are more polemically involved with American philosophy’s current status among the contemporary philosophical "schools," and still others seek to reveal the possibilities for the future of American philosophy. In thus addressing past, present, and future, the pieces, taken together, outline a trajectory for American philosophy that reinvents its importance from a new angle of vision. (shrink)

New technologies with military applications may demand new modes of governance. In this article, we develop a taxonomy of technology governance forms, outline their strengths, and red-team their weaknesses. In particular, we consider the challenges and opportunities posed by advancing artificial intelligence, which is likely to have substantial dual-use properties. We conclude that subnational governance, though prevalent and mitigating some risks, is insufficient when the individual rewards from societally harmful actions outweigh normative sanctions, as is likely to be the case (...) with AI. Nationally enforced standards are promising ways to govern AI deployment, but they are less viable in the “race-to-the-bottom” environments that are becoming common. When it comes to powerful technologies with military implications, there is only one multilateral option with a strong historical precedent: a non-proliferation plus norms-of-use regime, which we call NPT+. We believe that a non-proliferation regime may, therefore, be the necessary foundation for AI governance. However, AI may exhibit characteristics that would make a non-proliferation regime less effective than it has proven for nuclear weapons. As an alternative, verification-backed restrictions on AI development and use would address more risks, but they face challenges in the case of advanced AI, and we show how these challenges may not have technical solutions. Perhaps more importantly, we show that there is no clear example of major powers restricting the development of a powerful military technology when that technology lacks a ready substitute. We, therefore, turn to a final alternative, International Monopoly, which was the preferred solution of many scholars and policymakers in the early nuclear era. It should be considered again for governing AI: a monopoly would require less-invasive monitoring, though at the possible cost of eroding national sovereignty. Ultimately, we conclude that it is too soon to tell whether a non-proliferation regime, a verification-based regime, or an International Monopoly is most feasible for governing AI. Nonetheless, a variety of policies would yield a high return across all three scenarios, and we conclude by identifying some of these steps that could be taken today. (shrink)

The Encyclopedia of Organ includes articles on the organ family of instruments, including famous players, composers, instrument builders, the construction of the instruments, and related terminology. It is the first complete A-Z reference on this important family of keyboard instruments. The contributors include major scholars of music and musical instrument history from around the world.

Speakers of the “green backlash” movement frequently advertise their approach as one of rigorous scepticism, and themselves as defenders of scientific method. In reality, their use of scepticism is often highly flawed and inconsistent; this is clearly seen in case examples focusing on Philip Stott's arguments on climate change, and Julian Simon's arguments on physical limits to growth. What this discourse illustrates is that sceptical language is often used as a rhetorical tool for advancing an underlying political philosophy that is (...) based on an ideal of modern science as bestower of unlimited material power. In order to understand, and to criticise this discourse effectively, one needs to recall the criticisms made by the likes of Hayek and Arendt of “scientism”—the misuse of the language of science, and its aura of predictive certainty, to portray certain political visions as being inevitably true and triumphant.

The field of psychology, including cognitive science, is vexed by a crisis of confidence. Although the causes and solutions are varied, we focus here on a common logical problem in inference. The default mode of inference is significance testing, which has a free lunch property where researchers need not make detailed assumptions about the alternative to test the null hypothesis. We present the argument that there is no free lunch; that is, valid testing requires that researchers test the null against (...) a well-specified alternative. We show how this requirement follows from the basic tenets of conventional and Bayesian probability. Moreover, we show in both the conventional and Bayesian framework that not specifying the alternative may lead to rejections of the null hypothesis with scant evidence. We review both frequentist and Bayesian approaches to specifying alternatives, and we show how such specifications improve inference. The field of cognitive science will benefit because consideration of reasonable alternatives will undoubtedly sharpen the intellectual underpinnings of research. (shrink)

Einon's data support our original claims, although not a claim she seems to assume – of reciprocal attraction between elderly men and 20-year-old women. Implicit in her commentary is an assumption that genetic predispositions are omniscient fitness maximizers. Instead, evolutionary models assume selection-fashioned psychological mechanisms that, in the context of other mechanisms and pressures in past environments, had a positive effect on fitness relative to competing alternatives. The Over & Phillips data fit with our own data on homosexuals, and with (...) the assumption of independent modular mechanisms, rather than any existing sociocultural models. Einon also incorrectly assumes that evolutionary models have overemphasized male choice to the exclusion of female choice. (shrink)
