The spacing effect is among the most widely replicated empirical phenomena in the learning sciences, and its relevance to education and training is readily apparent. Yet successful applications of spacing effect research to education and training is rare. Computational modeling can provide the crucial link between a century of accumulated experimental data on the spacing effect and the emerging interest in using that research to enable adaptive instruction. In this paper, we review relevant literature and identify 10 criteria for rigorously (...) evaluating computational models of the spacing effect. Five relate to evaluating the theoretic adequacy of a model, and five relate to evaluating its application potential. We use these criteria to evaluate a novel computational model of the spacing effect called the Predictive Performance Equation. Predictive Performance Equation combines elements of earlier models of learning and memory including the General Performance Equation, Adaptive Control of Thought—Rational, and the New Theory of Disuse, giving rise to a novel computational account of the spacing effect that performs favorably across the complete sets of theoretic and applied criteria. We implemented two other previously published computational models of the spacing effect and compare them to PPE using the theoretic and applied criteria as guides. (shrink)

To function well in an unpredictable environment using unreliable components, a system must have a high degree of robustness. Robustness is fundamental to biological systems and is an objective in the design of engineered systems such as airplane engines and buildings. Cognitive systems, like biological and engineered systems, exist within variable environments. This raises the question, how do cognitive systems achieve similarly high degrees of robustness? The aim of this study was to identify a set of mechanisms that enhance robustness (...) in cognitive systems. We identify three mechanisms that enhance robustness in biological and engineered systems: system control, redundancy, and adaptability. After surveying the psychological literature for evidence of these mechanisms, we provide simulations illustrating how each contributes to robust cognition in a different psychological domain: psychomotor vigilance, semantic memory, and strategy selection. These simulations highlight features of a mathematical approach for quantifying robustness, and they provide concrete examples of mechanisms for robust cognition. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:LettersJames L. Walsh, Moira M. McQueen, Kevin O'Rourke, and Jean deBloisEarly Delivery of the Anencephalic InfantMadam:In the March 1994 issue of the Kennedy Institute of Ethics Journal, Kevin O'Rourke and Jean deBlois have replied to an article of ours (KIEJ, December 1993) on the early induction of the anencephalic fetus. They agree with our conclusion that such early delivery may be morally acceptable, but argue that (...) our justification is flawed. Exchanges on the subject probably could continue ad nauseam; here we simply state some of the elements of their article that leave us perplexed.1. The phrase "prolonging the life of" (p. 49) has one meaning in the case of artificial life supports, which may be unwarranted interventions, but it has a different meaning when it refers to not interfering with a person's enjoyment of necessary natural means of preserving his or her life. Inducing labor prior to viability, which denies the natural means of life support without a possible substitute, has more in common with smothering a dying patient than the nonemployment of or withdrawing of artificial means of life support. To refer to the death of the fetus here as an effect is rather like saying that I suffocated you and the effect of the suffocation is your death. This is quite different from induction after viability where the induction can have different effects.2. If the authors were correct that "the prohibition on inducing delivery before viability is predicated upon the assumption that the fetus in utero is a human being with the potential for further development" (p. 49) and the anencephalic has none, why is there need to employ the principle of double effect? They say that there is no moral obligation to prolong the life of the anencephalic fetus. Just as there is no need for the principle in cases of withdrawing unwarranted artificial life support, so there would be no need for it here. Because the authors seem to perceive a complete disjunction between direct and indirect killing (allowing to die being in the category of indirect killing), it seems that they are unable to let their argument rest here, but have to justify the death that occurs.3. The example concerning smothering and the nonemployment of aggressive interventions (p. 49) explains well the difference between killing and allowing to die. But allowing to die is not indirectly killing since it occurs as a result of the disease and not from the causality of the agent.4. How can we cause something and not intend it? There are instances in which we simply "permit" evil events, but where we are not the cause. For example, evil events may be attributable to the bad will of others. Legislators make just laws knowing that some people of bad will will break them for their own advantage. Here the legislators really do permit evil. Neither are we the cause of death when we allow a person to die by not imposing unwarranted means of life support; we permit his or her death. But can we so readily designate by "permit" [End Page 184] what we knowingly choose to bring about? O'Rourke and deBlois use interchangeably "indirectly intended" and "unintended" for what is caused by our actions; "indirectly intended" is a better designation than "unintended." The whole package, including all foreseen effects, is intended. Evil "happening" (p. 51) as a result of an action that I place can refer either to evil as caused by my action or to evil as arising from a cause apart from my action. Only in this latter sense do I permit evil and not intend it, either directly or indirectly.5. The fourth condition of the principle of double effect is given as follows: "There must be a proportionately grave reason for placing the act. The greater the evil, the more cogent the reason must be for performing the act" (p. 50). How the authors can abstract from balancing goods and evils here is beyond us.6. We cannot follow the authors' use of the term "morally good" with respect to the induced delivery (p. 50). The problem is concerned with the morally right... (shrink)

R. Kevin Hill argues that while Walsh is correct in urging caution regarding Rand's polemical characterizations of Kant, interpreting her charitably reveals surprising insights into the underlying structure of Kant's thought. Rand's objections to Kant's epistemology, psychology and metaphysics are truer to Kant's intentions than revisionist attempts to save him from himself. Her objections to Kantian ethics contain promising critiques of both Kant's rational reconstructive-methodology and his misuse of the concept of agent-neutral reasons. Lastly, though she paints too (...) broadly in her account of Kant's influence, two questionable tendencies in contemporary thought are traceable to him. (shrink)

James Walsh and Moira McQueen accurately conclude that the early delivery of anencephalic fetuses is morally acceptable, but the reasoning they use to reach that conclusion is flawed. First, the principle of double effect does not require a weighing of good and evil, but rather seeks a sufficient reason for tolerating the physical evil indirectly intended. Second, the principle of double effect requires a clear distinction between physical and moral causality. Third, the Catholic moral tradition will not admit direct (...) and intended killing of the innocent. Rather, early delivery of anencephalic fetuses is permissible because of the pathology associated with delivery of anencephalic fetuses at full term. Thus, the early delivery of an anencephalic infant is acceptable if the purpose of the moral act is avoiding a pathological condition on the part of the mother. (shrink)

A comprehensive treatment of the concept of causation in evolutionary biology that makes clear its central role in both historical and contemporary debates. Most scientific explanations are causal. This is certainly the case in evolutionary biology, which seeks to explain the diversity of life and the adaptive fit between organisms and their surroundings. The nature of causation in evolutionary biology, however, is contentious. How causation is understood shapes the structure of evolutionary theory, and historical and contemporary debates in evolutionary biology (...) have revolved around the nature of causation. Despite its centrality, and differing views on the subject, the major conceptual issues regarding the nature of causation in evolutionary biology are rarely addressed. This volume fills the gap, bringing together biologists and philosophers to offer a comprehensive, interdisciplinary treatment of evolutionary causation. Contributors first address biological motivations for rethinking evolutionary causation, considering the ways in which development, extra-genetic inheritance, and niche construction challenge notions of cause and process in evolution, and describing how alternative representations of evolutionary causation can shed light on a range of evolutionary problems. Contributors then analyze evolutionary causation from a philosophical perspective, considering such topics as causal entanglement, the commingling of organism and environment, and the relationship between causation and information.

Gleeson, Damian John In 1924, after a hiatus of a decade, the Australasian Catholic Record was re-established under the driving force of Monsignor John Joseph Nevin, the then vice-president of St Patrick's College, Manly. Mgr Nevin was ACR's principal editor up until 1937 and with the exception of a trip to Ireland and Europe in 1927, he contributed articles and answered questions on topics ranging across canon law, marriage, and moral theology in virtually every quarterly issue of ACR for more (...) than two decades. At Manly, he educated thousands of seminarians for dioceses across New South Wales and beyond, and was the college's president from 1929 to 1942. As such, Mgr Nevin was probably the most formidable Catholic clerical academic in New South Wales in the interwar period, yet we know little of this prodigious writer and intellectual who was a key adviser, not just to the Sydney hierarchy, but to a wide range of bishops. Apart from Dr Kevin Walsh's splendid history of St Patrick's College, Manly, church historians have not sought to consider the significant career of Mgr Nevin and his influence on several generations of clergy and bishops.

Two months after the attacks of 9/11, the Bush administration, in the midst of what it perceived to be a state of emergency, authorized the indefinite detention of noncitizens suspected of terrorist activities and their subsequent trials by a military commission. Here, distinguished Italian philosopher Giorgio Agamben uses such circumstances to argue that this unusual extension of power, or "state of exception," has historically been an underexamined and powerful strategy that has the potential to transform democracies into totalitarian states. The (...) sequel to Agamben's _Homo Sacer: Sovereign Power and Bare Life, State of Exception_ is the first book to theorize the state of exception in historical and philosophical context. In Agamben's view, the majority of legal scholars and policymakers in Europe as well as the United States have wrongly rejected the necessity of such a theory, claiming instead that the state of exception is a pragmatic question. Agamben argues here that the state of exception, which was meant to be a provisional measure, became in the course of the twentieth century a normal paradigm of government. Writing nothing less than the history of the state of exception in its various national contexts throughout Western Europe and the United States, Agamben uses the work of Carl Schmitt as a foil for his reflections as well as that of Derrida, Benjamin, and Arendt. In this highly topical book, Agamben ultimately arrives at original ideas about the future of democracy and casts a new light on the hidden relationship that ties law to violence. (shrink)

Although inference to the best explanation is ubiquitous in science and our everyday lives, there are numerous objections to the viability of IBE. Many of these objections have been thoroughly discussed, however, at least one objection to IBE has not received adequate treatment. We term this objection the “Disjunction Objection”. This objection challenges IBE on the grounds that it seems that even if H is the best explanation, it could be that the disjunction of its rivals is more likely to (...) be true. As a result, IBE appears to license accepting a hypothesis that is more likely than not to be false. Despite these initial appearances, we argue that the Disjunction Objection fails to impugn IBE.

Explanation and evidence are related in one way that is uncontroversial: evidence can confirm or disconfirm explanations. One explanation of Sally’s cold is that she has a virus; another is that she has a bacterial infection. The available evidence confirms the virus explanation because the evidence supports that colds are caused by viruses, not bacteria. A more interesting question concerns whether explanatory facts themselves provide evidence. That is to say, do we get evidence for p simply by realizing that p, (...) if true, would explain some data? Explanationists answer this question affirmatively, maintaining that explanatoriness is evidence of truth. (shrink)

Research on sexual harassment in the workplace has followed several trajectories: the extent of sexual harassment, labeling sexual harassment, responses to sexual harassment, and contributing factors to sexual harassment. Much of this research has been necessarily applied, leaving theoretical frameworks concerning sexual harassment underdeveloped. This research uses the case of the sexual harassment of temporary workers to develop grounded theory to provide a more structural understanding of sexual harassment. While temporary employment has increased dramatically in the past 15 years, researchers (...) have only recently begun to document the effects of this trend. This research is based on 68 in-depth interviews from two broader studies on clerical temporary work in Chicago and Los Angeles. The researchers find that the organization of temporary work fosters sexual harassment through the magnification of asymmetrical power relationships. (shrink)

Clearly we have entered an era of heightened interest in spirituality. The proliferation of books, music, and paraphernalia espousing the way of the spirit is a striking phenomenon. Everywhere there is a new willingness to admit that the categories of rational thought, the authority of science, are no longer adequate to the task of making sense of our lives. A search for meaning has become pervasive. Equally striking has been the rise of experiential religion. Evangelical and fundamentalist churches are the (...) fastest growing denominations worldwide. This is no accident, for they respond exactly to the failure of the modern forms of life. The modern ethos, for all its technological prowess, is experienced as an abyss of misery and confusion. The only way out is to leap over the entire modern perspective to locate oneself within the security of a divinely revealed faith. The difficulty, according to author David Walsh, is that neither the new age religions nor the old-time religions have enabled us to leap out of the modern world. The discovery of a source of meaning beyond that world does not automatically clarify all meaning within it. Finding a way to link the modern rational order and a spirituality pointing beyond it is what this book is about. Guarded By Mystery is a contemporary meditation on a problem that has been at the core of the human condition. It is intended for all who have been perplexed by the disconnection between the two worlds in which they live. Walsh explains how their experience of spiritual openness is meaningful within the modern world. He shows how that world is itself dependent on the same sources of spiritual illumination they have discovered within themselves. David Walsh is professor of politics at The Catholic University of America. He is the author of numerous works including, After Ideology: Recovering the Spiritual Foundations of Freedom, The Growth of the Liberal Soul, and The Third Millennium. " Walsh] writes about the spiritual quest in a time dubbed 'postmodern, ' meaning that the older rational securities have been shattered. Walsh ranges widely--from literary criticism to politics and art--in lifting up the luminous hints of the transcendent in the everyday. A most thoughtful reflection that should have a broad appeal."--First Things "At the beginning of a new century and new millennium, we can be grateful for such a wise and experienced guide as David Walsh as we explore the promise and pitfalls in our historical moment. Of most particular note is his intelligently hopeful understanding of the liberal democratic tradition and the ways in which modernity, after a century of catastrophically wrong turns, may now be fulfilling its aspiration toward transcendence. As he convincingly argues, the mystery to which contemporary thought is increasing open is not a threat but our surest guard."--Rev. Richard John Neuhaus, editor in chief, First Things "An engrossing read... a superb tract for the times that is just made to order.... Walsh's book is an apologia for the reality of God and for God's grounding of human existence on both the personal and socio-political levels in a postmodern time."--Prof. William M. Thompson, Duquesne University "Written for a general audience, yet informed by the wisdom of the ages and enlivened by an elegant gift of language, David Walsh's searching meditation on the heights and depths of human existence is a philosopher's illumination of reality of rare beauty and power. It ranges from politics to faith to the arts to find glimmers of hope and unsuspected sources of succor for a time out of joint. It celebrates the individual human person, as imago Dei, the abiding glory of creation. And it explores liberty, the prize of personality and of political order alike, through which we are uniquely drawn to meaningful partic. (shrink)

This paper argues for a postcritical praxis in global citizenship education (GCE) and peace education (PE). The paper begins by critiquing the interlocking fields of GCE and PE as problematically framed around the three key pillars of liberal peace. Then, drawing on postabyssal thinking the paper illustrates that the Western-centricity of liberal peacebuilding is not only colonialist/imperialist but that it is an erasure of the other. The paper argues that in light of this realization epistemological pluralism as a transformative response (...) is wanting. Instead new responses must focus on other ontological possibilities grounded in a postcritical response to postabyssal thought. Before concluding, the paper offers some pedagogic possibilities integrating the ontological for a new postcritical GCE and PE. (shrink)

Entanglement and non-locality are non-classical global characteristics of quantum states important to the foundations of quantum mechanics. Recent investigations have shown that environmental noise, even when it is entirely local in influence, can destroy both of these properties in finite time despite giving rise to full quantum state decoherence only in the infinite time limit. These investigations, which have been carried out in a range of theoretical and experimental situations, are reviewed here.

If it is true, as Raymond Boisvert wrote almost a decade ago in the Transactions of the Charles S. Peirce Society, that there are two schools of Dewey scholarship – the ‘method-centered’ set and the ‘lived experience’ group – then the publication of this manuscript, once thought lost, should be a force for reunification of the two. Indeed, providing a common vocabulary between science and generic values such as freedom and consummatory experience, a vocabulary generated through a critical the...

Virtue is an examination of central topics in ancient Greek explorations of "virtue," particularly the elusive notion of "Sophrosune," alternatively translated as "moderation" or "temperance". The book investigates central works of Plato and Aristotle to develop an understanding of the role this virtue plays in the broader ethical commitments of Socrates, Plato and Aristotle.

The argument between retributivists and consequentialists about what morally justifies the punishment of offenders is incoherent. If we were to discover that all of the contending justifications were mistaken, there is no realistic prospect that this would lead us to abandon legal punishment. Justification of words, beliefs and deeds, can only be intelligible on the assumption that if one's justification were found to be invalid and there were no alternative justification, one would be prepared to stop saying, believing or doing (...) what one has attempted to justify. Therefore, the moral standing or basis of our practices of punishing offenders can not rest on a justification of it. (shrink)

This study considered representations of divine and human others in the self-understanding of monotheists from three religions. Self-understanding was conceptualized on the basis of semantic and episodic knowledge in narrative response data. Given the importance of social context in the formation of cognitive schemas, the project emphasized self-understanding in a comparative religious design. The sample included sixty nominated religious exemplars who responded to a structured interview. Schemas were subsequently mapped for Jews, Muslims, and Christians by comparison of self and other (...) representations in a computational model known as latent semantic analysis (LSA). Findings indicated that representation of the divine is far removed from parents in cognitive schemas for all participants. Unlike Jews and Christians, Muslims appear to represent human others on the basis of self-understanding which principally references the divine. When considered in a computational semantic space, exemplars generally represent the self in a manner corresponding with divine and peer figures. (shrink)

The nature of the sales manager/salesperson relationship is examined. Our study investigates the level of agreement between sales managers and salespeople on the importance of the salesperson having specific internal virtues in order to do their job properly. Unlike external virtues that can be codified into codes of conduct, internal virtues are traits that cannot be codified but rather are part of the spiritual makeup of the person. Findings suggest that the level of agreement between sales managers and salespeople in (...) this area drives satisfaction with the sales manager and organizational commitment. Further, contrary to studies which use a summated job satisfaction measure, which consists of several facets of job satisfaction, satisfaction with the sales manager has a direct relationship with turnover intent.

Morality – the subjective sense that humans discern between right and wrong – plays a ubiquitous role in everyday life. Deontological reasoning conceptualizes moral decision-making as rigid, such that many moral choices are forbidden or required. Not surprisingly, the language used in measures of deontological reasoning tends to be rigid, including phrases such as “always” and “never.” Two studies drawn from two different populations used commonly used measures of moral reasoning and measures of morality to examine the link between individual (...) differences in deontological reasoning and language on the endorsement of moral foundations. Participants low on deontological reasoning generally showed less endorsement for moral principles when extreme language was used in the measures. (shrink)

In this paper I wish to discuss a problem which, though it has not in the recent past attracted the attention of many philosophers, nevertheless, in my opinion, belongs quite clearly to that branch of the subject which should rightly be called “philosophy of history”: the problem, namely, of history's intelligibility. Two main questions can be asked about this which it is important that philosophers should answer. The first is that of whether history is intelligible in the sense that we (...) can find intelligible connections bètween all or any of its parts. The significance of this question is apparent enough; for has not one of the philosopher's most pressing problems since Hume's time been that of whether any such connections are traceable in the world of fact? It is true that almost every theory on this subject has been put forward after a consideration of the sphere of physical nature only; but because this procedure has been universally followed, it is not therefore to be accepted as right. For history too offers us facts, and it is at least possible that these differ in important ways from those to be met with in nature, with the result that we can discover other sorts of connection between them than those which the physical sciences recognize. The possibility would seem to be worth investigation, and it is with it that I shall be concerned in the first part of my paper. In the other half I deal with the second main question about historical intelligibility. Supposing that we can find some cases of historical events being intrinsically, i.e. intelligibly related, we can go on to ask whether history is intelligible in a more ultimate sense. Is history, we can now inquire, a thing which is essentially rational, or is the rationality we can find in it of a merely superficial character? To put the problem somewhat more fully, is the historian able to do more than see intrinsic connections between the events which he investigates: can he go further and understand the course of history as a whole, so that he is able to say, in the popular phrases, that history “makes sense,” is “meaningful” and “has rhyme and reason” in it? It seems to me that this is a matter which certainly ought to be discussed by philosophers, if only for the assertion of history's rationality which some philosophers have made. (shrink)

Thinking about truth can be more dangerous than it looks. Of course, our concept of truth is the source of one of the most frustrating and impenetrable paradoxes humans have ever contemplated, the liar paradox, but that is just the beginning of its treachery. In an effort to understand why one of the most beloved and revered members of our conceptual repertoire could cause us so much trouble, philosophers have for centuries proposed “solutions” to the liar paradox. However, it seems (...) that our concept of truth takes offense to our efforts to understand it because it appears to retaliate against those who propose “solutions” to the liar. It takes its revenge on us by creating new paradoxes from our own attempts to find resolution. That is, most proposed solutions to the liar paradox give rise to new, more insidious paradoxes—often called revenge paradoxes. For our attempts at understanding, truth rewards us with inconsistent theories, untenable logics, and a deep feeling of bewilderment. It is as if our concept of truth lashes out at us because it wants to remain a mystery. After a few run-ins with truth, many philosophers have the good sense to keep their distance. Far from being the serene, profound concept most people take it to be, those of us who think much about the liar paradox know truth to be a vengeful bully—a conceptual misanthrope. (shrink)

_Media and Migration: Learning in a globalized wor_ld brings together studies located at the intersection of migration, media and learning, and considers how the learning practices of youth in migration are shaped by new media. The change in the mobilities of people, media, and material goods which allow new connections between 'global' and 'local' life has had a significant impact on contemporary migration, as well as social life more generally. The contributors to this book show how learning trajectories of individual (...) learners become defined by broadly distributed networks and knowledge systems. Learning in stable, closed, and culturally uniform settings is becoming the exception rather than the norm. While immigrant youth are often associated with juggling multiple lives or worlds, such juggling is increasingly becoming typical for all youth living with new media. The book therefore addresses youth learning more generally in relation to media, globalization, and diversity, as well as the digital learning practices of immigrants and non-immigrants. This book was originally published as a special issue of _Learning, Media and Technology. _. (shrink)

Abstract“[A]n der Front des Kampfes um den Menschen selbst”. Anthropogenetics and Anthropotechnics in Soviet Thought. The period between 1920 and 1930 reveals in Russia a practical manifestation of the technologies of the self, which see the body not only in a poetic‐symbolical way, but practically as a material of shaping and rebuilding. In this bio‐social discourse of a genetically perfected ‘new man’, Russian theorists of eugenics are looking back on traditional parallels of animal and plant breeding. The most influential group (...) of eugenics were the Russian biologists, especially the key players and the founders of the Russian genetics research Nikolai Kol′tsov (1872–1940) and Aleksandr Serebrovskii (1892–1948). It will be demonstrated that ‘human breeding’ (Russ. ‘Antropotekhnika’) is based both on the semantics and on the methodology of traditional animal and plant breeding. (shrink)
