Time underlies many interesting human behaviors. Thus, the question of how to represent time in connectionist models is very important. One approach is to represent time implicitly by its effects on processing rather than explicitly (as in a spatial representation). The current report develops a proposal along these lines first described by Jordan (1986) which involves the use of recurrent links in order to provide networks with a dynamic memory. In this approach, hidden unit patterns are fed back to themselves: (...) the internal representations which develop thus reflect task demands in the context of prior internal states. A set of simulations is reported which range from relatively simple problems (temporal version of XOR) to discovering syntactic/semantic features for words. The networks are able to learn interesting internal representations which incorporate task demands with memory demands: indeed, in this approach the notion of memory is inextricably bound up with task processing. These representations reveal a rich structure, which allows them to be highly context‐dependent, while also expressing generalizations across classes of items. These representations suggest a method for representing lexical categories and the type/token distinction. (shrink)

Individuals vary in the way they navigate through space. Some take novel shortcuts, while others rely on known routes to find their way around. We wondered how and why there is so much variation in the population. To address this, we first compared the trajectories of 368 human subjects navigating a virtual maze with simulated trajectories. The simulated trajectories were generated by strategy-based path planning algorithms from robotics. Based on the similarities between human trajectories and different strategy-based simulated trajectories, we (...) found that there is a variation in the type of strategy individuals apply to navigate space, as well as variation within individuals on a trial-by-trial basis. Moreover, we observed variation within a trial when subjects occasionally switched the navigation strategies halfway through a trajectory. In these cases, subjects started with a route strategy, in which they followed a familiar path, and then switched to a survey strategy, in which they took shortcuts by considering the layout of the environment. Then we simulated a second set of trajectories using five different but comparable artificial maps. These trajectories produced the similar pattern of strategy variation within and between trials. Furthermore, we varied the relative cost, that is, the assumed mental effort or required timesteps to choose a learned route over alternative paths. When the learned route was relatively costly, the simulated agents tended to take shortcuts. Conversely, when the learned route was less costly, the simulated agents showed preference toward a route strategy. We suggest that cost or assumed mental effort may be the reason why in previous studies, subjects used survey knowledge when instructed to take the shortest path. We suggest that this variation we observe in humans may be beneficial for robotic swarms or collections of autonomous agents during information gathering. (shrink)

Levinas and the Philosophy of Religion Jeffrey L. Kosky Reveals the interplay of phenomenology and religion in Levinas’s thought. "Kosky examines Levinas’s thought from the perspective of the philosophy of religion and he does so in a way that is attentive to the philosophical nuances of Levinas’s argument.... an insightful, well written, and carefully documented study... that uniquely illuminates Levinas’s work." —John D. Caputo For readers who suspect there is no place for religion and morality in postmodern philosophy, (...) class='Hi'>Jeffrey L. Kosky suggests otherwise in this skillful interpretation of the ethical and religious dimensions of Emmanuel Levinas’s thought. Placing Levinas in relation to Hegel and Nietzsche, Husserl and Heidegger, Derrida and Marion, Kosky develops religious themes found in Levinas’s work and offers a way to think and speak about ethics and morality within the horizons of contemporary philosophy of religion. Kosky embraces the entire scope of Levinas’s writings, from Totality and Infinity to Otherwise than Being, contrasting Levinas’s early religious and moral thought with that of his later works while exploring the nature of phenomenological reduction, the relation of religion and philosophy, the question of whether Levinas can be considered a Jewish thinker, and the religious and theological import of Levinas’s phenomenology. Kosky stresses that Levinas is first and foremost a phenomenologist and that the relationship between religion and philosophy in his ethics should cast doubt on the assumption that a natural or inevitable link exists between deconstruction and atheism. Jeffrey L. Kosky is translator of On Descartes’ Metaphysical Prism: The Constitution and the Limits of Onto-theo-logy in Cartesian Thought by Jean-Luc Marion. He has taught at Williams College.

The construction of geometrical concepts is familiar to readers of Kant’s _Critique of Pure Reason_ and _Prolegomena_ as the “shining example” [_glänzendes Beispiel_] of a priori cognition. So when Kant begins to offer constructions of concepts in physics in the _Metaphysical Foundations of Natural Science_, it seems unproblematic that mathematics is being applied to matter in motion. Much of Kant’s rhetoric suggests that nothing extraordinary is going on. And yet, constructions in Kant’s philosophy of physics display such peculiarities in comparison (...) to mathematical ones that they begin to seem like unfamiliar operations, distinct from constructions in pure mathematics.

Exploring the concepts of ethics, morality, and decision-making for the law enforcement community, Decision Point: Real-Life Ethical Dilemmas in Law Enforcement offers an inside look at the difficult challenges officers confront every day as they face ethical decisions that could drastically alter the course of their careers. Through a series of real-life vignettes, the book reviews specific scenarios, the actual decisions that were made, and the consequences and implications of these decisions. Focusing on the critical thinking needed for making appropriate (...) decisions, it retrospectively discusses considerations that were or should have been evaluated at the time. An engaging text ideal for classroom use, the book offers discussion questions at the end of each chapter that can be used as assignments, group breakout discussions, or professor-facilitated discussions.

Periodically in science there arrive on the scene what appear to be dramatically new theoretical frameworks (what the philosopher of science Thomas Kuhn has called paradigm shifts). Characteristic of such changes in perspective is the recasting of old problems in new terms. By altering the conceptual vocabulary we use to think about problems, we may discover solutions which were obscured by prior ways of thinking about things. Connectionism, artificial life, and dynamical systems are all approaches to cognition which are relatively (...) new and have been claimed to represent such paradigm shifts. Just how deep the shifts are remains an open question, but each of these approaches certainly seems to offer novel ways of dealing with basic questions in cognitive science. (shrink)

When corporations are accused of unethical behaviour by external actors, executives from those organizations are usually compelled to offer communicative responses to defend their corporate image. To demonstrate the effect that corporate executives'' communicative responses have on third parties'' perception of corporate image, we present the Corporate Communicative Response Model in this paper. Of the five potential communicative responses contained in this model (no response, denial, excuse, justification, and concession), results from our empirical test demonstrate that a concession is the (...) most effective and robust communicative option.

Although for many years a sharp distinction has been made in language research between rules and words—with primary interest on rules—this distinction is now blurred in many theories. If anything, the focus of attention has shifted in recent years in favor of words. Results from many different areas of language research suggest that the lexicon is representationally rich, that it is the source of much productive behavior, and that lexically specific information plays a critical and early role in the interpretation (...) of grammatical structure. But how much information can or should be placed in the lexicon? This is the question I address here. I review a set of studies whose results indicate that event knowledge plays a significant role in early stages of sentence processing and structural analysis. This poses a conundrum for traditional views of the lexicon. Either the lexicon must be expanded to include factors that do not plausibly seem to belong there; or else virtually all information about word meaning is removed, leaving the lexicon impoverished. I suggest a third alternative, which provides a way to account for lexical knowledge without a mental lexicon. (shrink)

In a contemporary world where political, environmental, and personal crises succeed one another without respite, it is no surprise that many resort to either nihilism or despair. From the Heart gives us reasons why we should still care--about anything. It finds support in authors as diverse as Friedrich Nietzsche and Saint Augustine, Soren Kierkegaard and Karl Ove Knausgaard, and in modern and contemporary artists such as Tehching Hsieh, Bas Jan Ader, and Christian Boltanski-all of whom provide material for a rich, (...) rewarding, heartfelt meditation. It speaks personally about "big questions," drawing on memoir, the arts, philosophy, religious traditions, and science. What does it mean for a heart to fail, to break, and what does it take to recover? Jeffrey Kosky shows us that attentive immersion in the natural and social worlds brings joy in both sickness and health, dying and living. (shrink)

This study investigates whether local gambling norms are associated with audit pricing. Using a religion-based measure of local social gambling norms, we find strong evidence that public firms located in U.S. counties with more liberal gambling norms exhibit higher levels of audit fees. This result is consistent with our view that, as an important external risk factor, clients’ local gambling norms influence audit pricing decisions. Our findings are robust to a battery of sensitivity tests, including non-religion based measures of liberal (...) gambling norms and a natural experiment. (shrink)

From their own practices, the authors offer insight into potential ethical dilemmas that may frequently develop in an applied psychology setting in which sport psychology is also being practiced. Specific ethical situations offered for the reader's consideration include confidentiality with coaches, administration, parents, and athlete-clients; accountability in ethical billing practices and accurate diagnosing; identification of ethical boundaries in nontraditional practice settings (locker room, field, rink, etc.); and establishment of professional competence as it relates to professional practice and marketing.

All ethics codes serve an argumentativefunction to improve public opinion, avoid government regulation, and produce ethical behavior among members. The National Religious Broadcasters' increased eforts to enforce its code illustrates the potential for three dificnlties to surface when organizations use codes to justify their activities. Organizations tend to limit public discussions to the code 's existence, and shorthand descriptions of it, fail to address enforceability problems, and assume that the code will change corporate culture. To overcome these problems, ongoing maintenance (...) of the code in relationship to its public context is required. (shrink)

El filósofo político de la Temprana Edad Moderna, Benedicto Spinoza, es a menudo visto como el padre del método crítico histórico para el estudio de la Biblia. A partir del trabajo de contemporáneos, Spinoza construyó el fundamento metodológico sobre el cual más tarde levantaría la crítica histórica. En este trabajo se examina el trasfondo político de la crítica bíblica de Spinoza, colocando así la obra de Spinoza en su contexto socio-histórico. La Guerra de los Treinta Años y la agitación política (...) en la República holandesa proveen el trasfondo próximo de la teoría política de Spinoza y de su crítica bíblica. (shrink)

We take our bearings from Francesco Negri — Although many persons attribute the origin of letter writing to various causes, I however believe that one to be closer to the truth that we have received, handed down by memory, from the ancient stories of Turpilius: namely, that the letter was invented for no other purpose than that we should make absent friends once more present [absentes amicos presentes redderemus] and that by regarding [intuentes] their letters we mightfor a time restore (...) the friendship interrupted by intervals of time and space; for since friendship is accustomed to making its foundation in daily companionship,when this thing is missing it seems indeed to weaken not a little.and hear in this passage the resonance of Aristotle:Is it then the same way with friends as with lovers, for whom seeing [to horon] the beloved is their greatest contentment, and the thing they choose over the other senses, since it is especially through seeing that love is present and comes to be present, so that for friends, too, living together [suzèn] is the most choiceworthy thing? For friendship is a sharing in common [koinònia]. (EN 1171b29–33)The audible connection with Aristotle is faint. Negri’s work is securely placed against the background of the increasing formalization of the art of letter writing in the Middle Ages and its Renaissance development, in which he figured prominently. The genealogy that he proposes, whose forebear is an all but forgotten Roman playwright, belongs to an account of literary tradition in which Cicero is the exemplary figure. Nonetheless, it is in St. Jerome that he finds the likely source of his attribution. (shrink)

Mitochondria are essential subcellular organelles containing an extranuclear genome (mtDNA). Mutations in mtDNA have recently been identified as causing a variety of human hereditary diseases. In most of these cases, the tissues of the affected individual contain a mixture of mutant and normal mtDNA, with this ratio determining the severity of symptoms. Stochastic factors alone have generally been believed to determine this ratio. Jenuth et al.(1), however, examining mice that contain a mixture of mtDNA types, show evidence of strong selective (...) forces at work in favoring one mtDNA variant over another in some tissues.

La pensée de Lévinas, du début jusqu’à la fin, est animée par le souci de libérer le moi du « mal de l’être » – c’est-à-dire, de l’expérience de l’être anonyme et irrémissible, sans fin ni commencement, que Lévinas nomme il y a. Dans les premiers ouvrages , l’autofondation du sujet répond à ce souci, mais cette tentative de libération échoue en tant qu’elle condamne le sujet à la présence toujours présente de lui-même et à sa persévérance dans l’effort d’être. (...) La notion de substitution que développera pleinement Autrement qu’être réussit là où la tentative des premiers ouvrages a échoué. La substitution dans la responsabilité libère la subjectivité mais, selon un paradoxe essentiel, la libère en la rendant otage de l’autre. Si la substitution dans la responsabilité est en effet l’événement de la subjectivation, comme le soutient Lévinas, alors il n’y a pas d’éthique sans libération et pas de libération sans éthique.Levinas’ thought, form start to finish, was animated by a concern for liberation of the self form the « evil of Being » – that is, form the experience of anonymous, irremissible Being without start or finish, which Levins names there is. In the early works , the autofoundation of the subject responds to this concern, but this attempt at liberation falls short as it condemns the subject to the ever present presence of itself and its perseverance in the effort of existing. The notion of substituion, developed most fully in Autrement qu’être, then succeeds xhere the aerlier effort failed. Substitution in responsibility liberates subjectivity, but, according to an essential paradox, liberates it as hostage of the other. If substitution in responsibility is indeed the event of subjectification, as Levinas argues, then there is no ethics without liberation, and no liberation without ethics. (shrink)

Levinas holds that ethics provides a figure of philosophical thought that is not ordered metaphysically and so allows us to explicate the significance of God whose fate is not linked with that of metaphysics, and his descrip- tion of ethics permits philosophy to bypass historical revelations pre- served by religious traditions as it articulates this significance of God. Nevertheless, Levinas's attempt to save the name "God" for that which responsibility witnesses is troubled in several ways: the responsible self cannot tell, (...) and cannot tell us, whether its responsibility witnesses God since (1) both it and God are outside the order (metaphysics and consciousness) where identification would be possible and (2) the anonymity of this God and the trauma suffered by the self are disturbingly close to the menace of the anonymous il y a as that anonymity has been described in Levinas's earlier work.

The goal of this essay is to begin the study of the handful of references to celestial divination found in the Assyrian royal inscriptions from the perspective of propaganda analysis by approaching one text in particular, Esarhaddon’s Aššur A inscription. This inquiry helps to solve some of the outstanding problems in regard to the celestial phenomena recorded in these inscriptions and their mantic implications.
