La teoría depredador-presa sugiere que los depredadores generalistas están vinculados a la estabilidad demográfica de las presas, mientras que los especialistas son desestabilizadores. En este artículo hemos hecho una revisión general de las consecuencias demográficas de diferentes estrategias de depredación y hemos intentado testar la hipótesis de que la caza de subsistencia se produce de forma oportunista, la caza de persecución sería la realizada por depredadores especializados y la caza recreativa por depredadores generalistas. Desde esta hipótesis, la caza de persecución (...) tendría efectos desestabilizadores, mientras que los efectos de la caza de subsistencia y recreativa serían neutrales o estabilizadores. Hemos encontrado poco apoyo empírico para esta hipótesis, pero también es cierto que contamos con escasa información de campo. Los cazadores de recreo principalmente cazan de forma oportunista y la caza de persecución muestra una respuesta funcional de tipo III, es decir, disminuye la intensidad de presas cuando lo hace la abundancia de presas y aumenta dicha intensidad ante cierto nivel de abundancia de presas. Sugerimos que los cazadores de recreo limitan los efectos desestabilizadores sobre las poblaciones de caza y que la caza no es un método eficaz de eliminación completa de especies invasoras. Instamos a la realización de nuevos estudios que cuantifiquen las respuestas de los cazadores a la abundancia de presas, en particular estudios que evalúen las respuestas de los cazadores de subsistencia y la persecución ilegal.

In 'Een handvol filosofen' staan de filosofen centraal die sinds de oprichting van de Vrije Universiteit in 1880 aan deze instelling verbonden zijn geweest. Het gaat hierbij niet alleen om de inhoud van hun werk, maar ook om de personen zelf. Er waren filosofiedocenten die zich met de universiteit identificeerden en zich volledig konden ontplooien. Er waren er echter ook voor wie dit niet gold, die geïsoleerd of in gewetensnood raakten. Veel filosofiestudenten waren actief betrokken bij wat er in hun (...) faculteit gebeurde. Zij namen initiatieven, protesteerden soms tegen de gang van zaken en kozen partij in conflictsituaties. Sinds het eind van de jaren zestig van de twintigste eeuw verloor de Vrije Universiteit geleidelijk haar christelijk karakter. Tegenwoordig werken alle stafleden vanuit hun eigen motivatie mee aan een hoofdzakelijk seculier geworden universiteit, die ruimte biedt voor religieuze en levensbeschouwelijke diversiteit. (shrink)

A promise to do some action seems to create a binding obligation to do that action. And yet, paradoxically, an obligation seems not to be a fact that we can create or bring into existence; we can create an obligation only by creating or bringing into existence something else. The only way to avoid the paradox is to show that the act of promising creates something other than an obligation, which nonetheless binds us to perform the action in question. After (...) considering and rejecting various options such as the promisee's expectation and the promisor's resolve, Prichard locates the bindingness of a promise in a prior general promise, which allows the noises we make when promising to generate an obligation to perform the promised action.

Currently, there is widespread skepticism that higher cognitive processes, given their apparent flexibility and globality, could be carried out by specialized computational devices, or modules. This skepticism is largely due to Fodor's influential definition of modularity. From the rather flexible catalogue of possible modular features that Fodor originally proposed has emerged a widely held notion of modules as rigid, informationally encapsulated devices that accept highly local inputs and whose operations are insensitive to context. It is a mistake, however, to equate (...) such features with computational devices in general and therefore to assume, as Fodor does, that higher cognitive processes must be non‐computational. Of the many possible non‐Fodorean architectures, one is explored here that offers possible solutions to computational problems faced by conventional modular systems: an ‘enzymatic’ architecture. Enzymes are computational devices that use lock‐and‐key template matching to identify relevant information (substrates), which is then operated upon and returned to a common pool for possible processing by other devices. Highly specialized enzymes can operate together in a common pool of information that is not pre‐sorted by information type. Moreover, enzymes can use molecular ‘tags’ to regulate the operations of other devices and to change how particular substrates are construed and operated upon, allowing for highly interactive, context‐specific processing. This model shows how specialized, modular processing can occur in an open system, and suggests that skepticism about modularity may largely be due to failure to consider alternatives to the standard model.

Die in diesem Bande vereinigten Aufsatze dokumentieren die siebte einer Reihe thematisch aufeinander bezogener Arbeitstagungen von Indologen, Buddhologen und Theologen, zu der das Institut fur Kultur- und Geistesgeschichte Asiens der Osterreichischen Akademie der Wissenschaften eingeladen hatte, und die im September 2000 unter dem Titel "Mythisierung der Transzendenz als Entwurf ihrer Erfahrung" stattfand. Zur Diskussion stand die Tragweite und Anwendbarkeit des Begriffes "Mythisierung", ein zentraler Terminus der Religionshermeneutik Gerhard Oberhammers. Dieser Begriff ermoglichte es den Beitragenden nicht nur, den Gegensatz von Erfahrung, (...) Sprache und Transzendenz in den unterschiedlichen Religionen zu problematisieren, sondern mit ihm konnte auch auf die Bedingungen jeder historisch-konkreten Religion reflektiert werden. Zu den theologischen und philosophischen Beitragen gehoren: Gerhard Oberhammer, Mit-sein, Mythisierung und Transzendenz. Einleitende Gedanken; Siegfried Wiedenhofer, "Mythisierung der Transzendenz". Zwischen Offenbarungsereignis und Traditionsvermittlung; H. J. Adriaanse, Wort, Offenbarung und Theologie als Momente der Mythisierung. Karl Barths Theologie des Wortes Gottes als Prufstein eines religionshermeneutischen Grundbegriffs; Desiree J. Berendsen, Mythisierung der Transzendenz als Ordnung des Lebens. Uber Kierkegaard und Oberhammer; Marcus Schmucker, Von der individuellen Erfahrung zum Text; Norbert Hintersteiner, Von der Gebung des Unendlichen. Phanomen und Transzendenz bei Jean-Luc Marion. Shizuteru Ueda, Mythisierung und Ent-Mythisierung der Transzendenz als Entwurf ihrer Erfahrung im Zen-Buddhismus; Hans-Peter Muller, Mythisierung geschichtlicher Ereignisse im Alten Testament und im Alten Vorderen Orient; Lourens Minnema, Bildlose Bildhaftigkeit.

Dion is a human person, Lefty is his left foot, and Theon is Lefty-Complement, a proper part of Dion. Lefty is annihilated and Dion survives left-footless. After Lefty’s annihilation Theon, if he survives, occupies the same region as Dion. I suggest that this scenario be understood as a fusion case in which Dion and Theon, initially overlapping but distinct, are identical after Lefty’s annihilation and propose an account of proper names that allows us to say that Dion and Theon have (...) ‘become identical’ without commitment to occasional identity or other controversial metaphysical doctrines. The proposed solution employs the semantics developed by Wolfgang Schwarz to address the ‘paradox of occasional identity’, posed by puzzle cases of fission, to deal with the problem of Dion and Theon, a body-minus puzzle.

I bogen "Den store humor" undersøger Harald Høffding humoren som livsanskuelse. "Den store humor" er ifølge Høffding en etisk livsholdning, som et menneske kan leve sit liv efter. Inspireret af filosoffen Søren Kierkegaards stadieteori karakteriserer Harald Høffding humoren som et etisk standpunkt, der nægter at anerkende den kristnes tragiske syn på livet. I stedet formår humoristen, at balancere livets lyse og skyggefulde sider. Humoristen lever sit liv med åbne øjne og har derfor blik for såvel verdens komik som tragik. Harald (...) Høffding (1843-1931) var teolog og filosof og virkede gennem 30 år som professor ved Københavns Universitet. I løbet af sin karriere opnåede han en central position i det danske videns- og kulturliv og nød stor anerkendelse både i og udenfor Danmark. Høffding var yderst virksom hele sit liv, og tankegodset i hans bøger er stadig relevant i dag. Udover værkerne om etik, filosofihistorie og psykologi kendes han for monografier om Søren Kierkegaard, Jean-Jacques Rousseau og Baruch Spinoza. (shrink)

The paper proposes to integrate literary studies in consciousness research to develop a strong ethical and existential dimension in the field. More specifically, it considers the value of fictional narrative for developing concepts of selfhood and personal identity that cohere with the reductionist explanations of human consciousness and self in modern empirical consciousness research. My central claim is that looking to the literary representations of human consciousness and existence that reject or are free from conventional essentialist ideas of self, agency, (...) and anthropocentrism can help 'normalize' the reductionist scientific descriptions of humans and reduce their psychologically and socio-culturally disruptive impact. The paper uses Virginia Woolf's The Waves as an example, showing how the novel's non-anthropocentric and non-essentialist conceptions of self and consciousness overlap with materialist theories in neuroscience and -philosophy but present these in a distinctive narrative framework and poetic terms that bring out the inherent emancipatory potential of the materialist explanation of human existence and offer the reader the possibility of relating to these experientially and emotionally.

Many people are worried about the harmful effects of climate change but nevertheless enjoy some activities that contribute to the emission of greenhouse gas (driving, flying, eating meat, etc.), the main cause of climate change. How should such people make choices between engaging in and refraining from enjoyable greenhouse-gas-emitting activities? In this chapter, we look at the answer provided by decision theory. Some scholars think that the right answer is given by interactive decision theory, or game theory; and moreover think (...) that since private climate decisions are instances of the prisoner’s dilemma, one rationally should engage in these activities provided that one enjoys them. Others think that the right answer is given by expected utility theory, the best-known version of individual decision theory under risk and uncertainty. In this chapter, we review these different answers, with a special focus on the latter answer and the debate it has generated. (shrink)

The impact of digital media and technology on performance arts is evident when digital visual effects (VFX) filming techniques are introduced on a film set. Digital technologies influence the film actor’s approach to be congruent to and authentic within the circumstances of the scene. Actors require an effective skillset and strategies to successfully deliver an embodied performance aligning with the various digital VFX techniques. Focusing on imagination, action and emotion that would facilitate such an embodied performance, we drew on relevant (...) neuroscientific notions such as neuron reactivation, conceptual blending, as-if body states and affordances. Additionally, we incorporated relevant embodied performance concepts from Stanislavski, Laban/Bartenieff Movement Studies, Effector Patterns including the Emotional Body Approach and Lessac Kinesensics to the development of a digital acting programme, advancing the actor’s required skills and providing on-set digital acting strategies to support congruency with digital VFX and authenticity within the diegetic reality. The efficacy of this programme was determined by assessing pre- and post-intervention recordings of both a control and an experimental group of trained actors. Reflection-on-action journals from participants supplemented the assessment. The assessments and journals indicate that the acquired skillset and on-set digital acting strategies effectively improve the actor’s performance with digital VFX filming technology. (shrink)

The Shape of Thought: How Mental Adaptations Evolve presents a road map for an evolutionary psychology of the twenty-first century. It brings together theory from biology and cognitive science to show how the brain can be composed of specialized adaptations, and yet also an organ of plasticity. Although mental adaptations have typically been seen as monolithic, hard-wired components frozen in the evolutionary past, The Shape of Thought presents a new view of mental adaptations as diverse and variable, with distinct functions (...) and evolutionary histories that shape how they develop, what information they use, and what they do with that information. The book describes how advances in evolutionary developmental biology can be applied to the brain by focusing on the design of the developmental systems that build it. Crucially, developmental systems can be plastic, designed by the process of natural selection to build adaptive phenotypes using the rich information available in our social and physical environments. This approach bridges the long-standing divide between "nativist" approaches to development, based on innateness, and "empiricist" approaches, based on learning. It shows how a view of humans as a flexible, culturally-dependent species is compatible with a complexly specialized brain, and how the nature of our flexibility can be better understood by confronting the evolved design of the organ on which that flexibility depends.
