Abstract“Sign stimuli” elicit specific patterns of behavior when an organism's motivation is appropriate. In the toad, visually released prey-catching involves orienting toward the prey, approaching, fixating, and snapping. For these action patterns to be selected and released, the prey must be recognized and localized in space. Toads discriminate prey from nonprey by certain spatiotemporal stimulus features. The stimulus-response relations are mediated by innate releasing mechanisms (RMs) with recognition properties partly modifiable by experience. Striato-pretecto-tectal connectivity determines the RM's recognition and localization (...) properties, whereas medialpallio-thalamo-tectal circuitry makes the system sensitive to changes in internal state and to prior history of exposure to stimuli. RMs encode the diverse stimulus conditions referring to the same prey object through different combinations of “specialized” tectal neurons, involving cells selectively tuned to prey features. The prey-selective neurons express the outcome of information processing in functional units consisting of interconnected cells. Excitatory and inhibitory interactions among feature-sensitive tectal and pretectal neurons specify the perceptual operations involved in distinguishing the prey from its background, selecting its features, and discriminating it from predators. Other connections indicate stimulus location. The results of these analyses are transmitted by specialized neurons projecting from the tectum to bulbar/spinal motor systems, providing a sensorimotor interface. Specific combinations of such projective neurons – mediating feature- and space-related messages – form “command releasing systems” that activate corresponding motor pattern generators for appropriate prey-catching action patterns.

"I cannot recommend this book highly enough!" Is this statement true or have I succeeded in lavishing enough praise on this book by writing this statement, making this statement in fact false? This is one way in which Adamson and Ganeri explain the view of the Buddhist philosopher Nāgārjuna that everything is empty. Nāgārjuna has to defend himself against the objection that if everything is "empty" then this surely also applies to his own view. He famously argues that he does (...) not have a thesis and provides the "silence" analogy, which I want to illustrate using my own example: if there is too much off-topic... (shrink)

Die im Reader versammelten Beiträge verstehen sich als Versuche zu einer Soziologie des Visuellen. Sie untersuchen am Beispiel des Mediums Stadtfilm, welche Rolle die dorterzeugten Bilder großer Städte bei der Produktion urbanistischer Repräsentanten spielen. Aus diesem Grund werden insbesondere Übergänge analysiert, die Spielfilme einerseits und urbanistische Diskurse andererseits miteinander verknüpfen. Gemeinsamer Ausgangspunkt ist die These, daß es vor allem Bilder sind, die solche Verknüpfungen gewährleisten. Es wird unterstellt, daß es das Medium Film erlaubt, gerade über den Einsatz von Bildern "näher" (...) an soziale Wirklichkeiten heranzukommen, als dies textzentrierter Praxis empirischer Sozialforschung möglich ist. Stadtfilme erzeugen wirkmächtige Bilder, auf die dann unter bestimmten Bedingungen in urbanistischen Kontexten zurückgegriffen wird. Die Autoren präsentieren konzeptionelle Überlegungen und Filminterpretationen zu Moebius (1991, Regie: Matti Geschonneck), Der Himmel über Berlin (1987, Regie: Wim Wenders), In weiter Ferne, so nah! (1993, Regie: Wim Wenders), Der Bauch des Architekten (1987, Regie: Peter Greenaway) und Hass (1995, Regie: Mathieu Kassovitz). Sie bedienen sich dabei sehr unterschiedlicher Verfahren. Gemeinsam sind ihnen allerdings die Anliegen, die größere Nähe der Filme zu sozialen Welten hervorzuheben und die Übergänge zwischen Stadtfilmen und Urbanistik herauszuarbeiten. -/- City and Film. Attempts at a 'Visual Sociology' Summary The contributions collected in this reader present attempts at a Visual sociology'. Based on a study on the medium 'city film' the author s determine which role the images of big cities evoked in such films can play for urbanistic representations. Therefore the analysis is, in particular, focussed on points of transition marking a connection of movies, on the one hand, and urbanistic discourse, on the othe r. The common point of departure is the hypothesis that images, more than anything else, do guarantee such connections. The authors assume that the medium film may lead 'closer' to social realities than the text- centered practices of empirical social research. City films produce powerful images which, under certain cond itions, can be utilized in urbanistic contexts. The authors present conceptual considerations and interpretations of the following films: Moebius (1991, director: Matti Geschonneck); Der Himmel über Berlin (1987, director: Wim Wenders); In weiter Ferne, so nah! (1993, director: Wim Wenders); The Belly of the Architect (1987, director: Peter Greenaway); and quite different methods they aim at the same goals: emphasizing the greater closeness of films to social worlds and bringing out the points of transition between city films and urbanistics.

Using the lens of positive organizational ethics, we theorized that empathy affects decisions in ethical dilemmas that concern the well-being of not only the organization but also other stakeholders. We hypothesized and found that empathetic managers were less likely to comply with requests by an authority figure to cut the wages of their employees than were non-empathetic managers. However, when an authority figure requested to hold wages constant, empathy did not affect wage cut decisions. These findings imply that empathy can (...) serve as a safeguard for ethical decision making in organizations during trying times without generally undermining organizational effectiveness. We conclude by discussing the implications of our research. (shrink)

An important part of friendships are the so-called special obligations generated by them. Friends owe things to each other that they do not owe to strangers. While such special obligations are an important part of our everyday practice, they raise several philosophical questions. These questions include the status of special obligations (are such obligations sui generis or is it possible to reduce them to general moral principles?), the source of such special obligations (what grounds special obligations of friendship?), and the (...) content of special obligations (what is the content of special obligations of friendship?). This chapter gives an overview of some of the most important positions in the literature with regard to these questions. (shrink)

The Colombian-born photographer and artist Guadalupe Ruiz has undertaken a project to document the social and economic inequity in her native city of Bogotá. She explores six houses from the city's six different taxation classes whose residents range from extremely affluent to impoverished. By taking photographs of apartments and streetscapes, whole interiors and single pieces of furniture, Ruiz creates a cohesive and multilayered portrait of the city as a whole. She also examines personal and decorative objects, such as family portraits (...) and Catholic icons found in both slums and luxurious villas, and highlights the differences and some surprising cultural parallels between socioeconomic classes. Guadalupe Ruiz— Bogotá D. C. is a subtle, thought-provoking examination of urban life and includes over a hundred stunning images arranged by neighborhood. A map of the neighborhoods and a complementary essay are included to provide context for Ruiz's impressive photographs. Text in English, French, Spanish, and German. (shrink)

Immigrants now compose approximately 12 of the population of the United States and a sizable proportion of the workforce. Yet in contrast to research on other traditionally under-represented groups (e.g., women, African Americans), there are relatively few studies on issues related to being an immigrant in the U.S. workforce. This study examined English-only workplace policies, focusing on reactions to business justifications – explanations that justify managerial decisions as business necessities – for these policies. We contrasted the reactions of individuals coming (...) from immigrant families, where at least one parent was an immigrant to the U.S., with those of persons from non-immigrant families. Results of an experiment indicated that business justifications were successful in influencing the attitudes of non-immigrants toward the English-only policies, but did not influence the attitudes of individuals from immigrant families. Probing the reasons for this effect, a thought-listing protocol suggested that non-immigrants mentioned more of the business benefits of the English-only policy than did individuals from immigrant families. Further, business justifications for the English-only policy led individuals from immigrant families, but not those from non-immigrant families, to view the organization as being less ethical and less concerned with the welfare of its workers. The implications of messages from management being understood differently by different demographic groups are discussed. (shrink)

A complete system of classical Aristotelian logic intended for honors high school and college.

En este trabajo sobre los pensadores novohispanos Alonso de la Veracruz y Tomás de Mercado se seguirá la argumentación de un tema escasamente explorado: el papel fundacional de la ley natural y su interpretabilidad a través de la ley humana. Se mostrará que ambos autores, basados en las tradiciones salamantinas del siglo XVI, introducen un método que afirmaría la validez de la ley natural y, al mismo tiempo, permitir aplicaciones diversas de los parámetros normativos de la ley humana. Esto es (...) posible, como lo sostiene Veracruz en su crítica al diezmo para los pueblos indígenas, cuando la ley natural tenga que reinterpretarse a partir de hechos sociales concretos o cuando, como en el caso de Mercado, la ley humana sea congruente con la ley natural y, no obstante, tenga que desacatarse para evitar perjuicios personales o públicos en el plano comercial.

Ohne Rücksicht auf disziplinäre Schranken bringt dieses Buch verschiedene nicht-reduktionistische Lerntheorien miteinander ins Gespräch. In einem offenen Diskurs, der die Konzepte zueinander in Beziehung setzt, werden die unterschiedlichen Perspektiven kritisch abgewogen und hinsichtlich ihrer Stärken und Schwächen diskutiert.

Delo se loteva vprašanja aktualnosti pojma subjekta v filozofiji in politiki skozi analizo tistih avtorjev, ki so ga domnevno najbolj radikalno pokopali: pokaže, da vznik radikalno novega in problematika subjekta zavzema osrednje mesto v Deleuzovi filozofiji, kakor tudi v Lyotardovi pozni misli posvečeni praznini, v Foucaultovi obravnavi biopolitike in biooblasti, v delu Negrija in Hardta o Imperiju, ter nazadnje v Badioujevi predelavi temeljnih filozofskih kategorij biti, resnice in subjekta, na osnovi katerih je dandanes znova možna renesansa filozofije. Ta ima po (...) Badiouju štiri razsežnosti, ki se v delu Vznik subjekta nenehno prepletajo: »V osnovi želja filozofije implicira razsežnost upora: ni filozofije brez nezadovoljstva mišljenja v njegovem soočenju s svetom, kakršen je. Pa vendar želja filozofije vključuje tudi logiko: to je, prepričanje v moč argumenta in uma.«. (shrink)

Richard of St. Victor's elaboration of the themes of interpersonal relations and of human love as self-transcendence links him to contemporary philosophical and theological interests.

This article describes a challenge to the cultures and religions of the world that the author believes is the greatest challenge that has confronted the human race in its entire history. Modernity's search for unity and postmodernity's affirmation of pluralism reflect aspects of our current situation, but more needs to be recognized. We must acknowledge that East and West must face the current challenges together. Multiculturalism and unity encompass all world cultures, and we cannot be content to read our present (...) history only through the lens of western developments. Karl Jaspers's theory of the First Axial period of history, 800‐200 B.C.E., in which all the present world religions have their roots, is useful. It reveals that our present flowering of culture and spirit in the Western world, including our science, is not so much a product of the Western Renaissance and Enlightenment, as it is rooted in cultural events that belong to East and West equally. We are now in the Second Axial Period, which challenges the world religions to allow their energies to move toward convergence, just as in the previous millennia they moved toward differentiation. Teilhard de Chardin's thought is a guide for us, in his vision of a complex convergence of consciousness, in which differences will not be abolished but will be transformed in their coming together. This convergent perspective will also join with the perspective of rediscovering our roots in the earth, and it will repossess the spirituality of the primal peoples, in its understanding of the entire human race to be one tribe. The world religions are faced with the task, therefore, of encountering each other in “dialogic dialogue,” and channeling their spiritual resources toward the solution of real‐world global problems.

To what extent do aesthetic taste and our interest in the arts constitute who we are? In this paper, we present a series of empirical findings that suggest an Aesthetic Self Effect supporting the claim that our aesthetic engagements are a central component of our identity. Counterfactual changes in aesthetic preferences, for example, moving from liking classical music to liking pop, are perceived as altering us as a person. The Aesthetic Self Effect is as strong as the impact of moral (...) changes, such as altering political partisanship or religious orientation, and significantly stronger than for other categories of taste, such as food preferences. Using a multidimensional scaling technique to map perceived aesthetic similarities among musical genres, we determined that aesthetic distances between genres correlate highly with the perceived difference in identity. Further studies generalize the Aesthetic Self Effect beyond the musical domain: general changes in visual art preferences, for example from more traditional to abstract art, also elicited a strong Self Effect. Exploring the breadth of this effect we also found an Anaesthetic Self Effect. That is, hypothetical changes from aesthetic indifference to caring about music, art, or beauty are judged to have a significant impact on identity. This effect on identity is stronger for aesthetic fields compared to leisure activities, such as hiking or playing video games. Across our studies, the Anaesthetic Self Effect turns out to be stronger than the Aesthetic Self Effect. Taken together, we found evidence for a link between aesthetics and identity: we are aesthetic selves. When our tastes in music and the arts or our aesthetic interests change we take these to be transformative changes. (shrink)

The relationship of part to whole is one of the most fundamental there is; this is the first and only full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology. Peter Simons surveys and criticizes previous theories, especially the standard extensional view, and proposes a more adequate account which encompasses both temporal and modal considerations in detail. 'Parts could easily be the standard book on mereology for the next (...) twenty or thirty years.' Timothy Williamson, Grazer Philosophische Studien. (shrink)

This article makes a contribution to debates in recognition theory by expanding the taxonomy of (mis-)recognition in the economic sphere. It argues that doing justice to the variety of ways in which recognition is engaged in economic relationships requires: (1) taking into consideration not just the recognition principle of esteem, but also (various aspects of) need and respect; (2) distinguishing a productive from a consumptive dimension with regards to each principle of recognition (need, esteem and respect); and (3) identifying the (...) specific economic relationship at stake (e.g. between consumers and producers, or between employers and employees). In this way, we can account for the diversity of demands for recognition made in the economic sphere, explain what underpins them, and bring structure into these diverse phenomena. What is more, this expanded taxonomy is a useful tool for social pathology theorists, who should appreciate the full range of variants of misrecognition when diagnosing pathologies of misrecognition in the economic sphere.

Climate change poses a serious problem for established ethical theories. There is no dearth of literature on the subject of climate ethics that break down the complexity of the issue, thereby enabling one to arrive at partial conclusions such as: 'historical justice demands us to do this...' or 'intergenerational justice demands us to do that...'. In contrast, this article attempts to face up to this complexity, that is: to end with a synthesis of the arguments into what can be considered (...) to be the most reasonable and fairest approach to the politics of climate change on a global scale. A significant part of the paper is devoted to the questions whether or not a) historical emissions and b) population changes are relevant to how emissions rights should be distributed. I discuss the merits and drawbacks of each perspective and briefly outline the normative justifications. (shrink)

Indian Epistemology and Metaphysics introduces the reader to new perspectives on Indian philosophy based on philological research within the last twenty years. Concentrating on topics such as perception, inference, skepticism, consciousness, self, mind, and universals, some of the most notable scholars working in classical Indian philosophy today examine core epistemological and metaphysical issues. Philosophical theories and arguments from a comprehensive range of Indian philosophical traditions (including the Nyaya, Mimamsa, Saiva, Vedanta, Samkhya, Jain, Buddhist, materialist and skeptical traditions, as well as (...) some 20th century thought) are covered. The contributors to this volume approach the topics from both a philosophical and a philological perspective. They demonstrate the importance of the subject matter for an understanding of Indian thought in general and they highlight its wider philosophical significance. By developing an appreciation of classical Indian philosophy in its own terms, set against the background of its unique assumptions and historical and cultural development, Indian Epistemology and Metaphysics is an invaluable guide to the current state of scholarship on Indian philosophy. It is a timely and much-needed reference resource, the first of its kind. (shrink)

Two kinds of membrane contacts in the vertebrate lens are described. Fiber gap junctions are domains where small molecules can pass between lens cells. Membrane structures of ball‐and‐socket type interlock adjacent lens fibers and thus contribute to the structural integrity of the lens. Both of these membrane contacts appear crucial for the maintenance of lens transparency.

The intercellular junctions connecting the cytoplasms of fibre cells in the mammalian lens have until recently been regarded as a class of junction which is fundamentally different from that of the gap junctions in other organs. Recent observations, however, suggest that the lens junctions fit protein topology predictions common for all gap junctions. While the homologous peptide portions are predicted to form the channels, the divergent peptide portions of the gap junction polypeptides may adapt channel activity to the special tissue (...) requirements.

There has been a long tradition of characterizing man as the animal that is capable of propositional language. However, the remarkable ability of using pictures also only belongs to human beings. Both faculties however depend conceptually on the ability to refer to absent situations by means of sign acts called 'context building'. The paper investigates the combined roles of quasi-pictorial sign acts and proto-assertive sign acts in the situation of initial context building, which, in the context of “concept-genetic” considerations, aims (...) for a philosophical explanation of the anthropological functon of pictures and their relation to imagination.
