This massive two-volume reference presents a comprehensive selection of the most important works on the foundations of mathematics. While the volumes include important forerunners like Berkeley, MacLaurin, and D'Alembert, as well as such followers as Hilbert and Bourbaki, their emphasis is on the mathematical and philosophical developments of the nineteenth century. Besides reproducing reliable English translations of classics works by Bolzano, Riemann, Hamilton, Dedekind, and Poincare, William Ewald also includes selections from Gauss, Cantor, Kronecker, and Zermelo, all translated here (...) for the first time.

This paper discusses how facet-like structures occur as a commonplace feature in a variety of computer science disciplines as a means for structuring class hierarchies. The paper then focuses on a mathematical model for facets (and class hierarchies in general), called formal concept analysis, and discusses graphical representations of faceted systems based on this model.

Un estudio de caso de investigación socio-ecológica realizado en Puerto Williams, Cabo de Hornos (Chile), revela que las personas pertenecientes a diferentes grupos socioculturales poseen una diversidad de perspectivas y relaciones con la naturaleza. Por ejemplo, los miembros de la Comunidad Indígena Yagán y los antiguos residentes (en su mayoría descendientes de colonos de principios del siglo XX), expresaron un fuerte sentimiento de pertenencia y hogar. Sin embargo, las personas identificadas con el uso de los recursos no tuvo respuestas positivas (...) respecto al sentimiento de hogar. Entre los entrevistados, el concepto de un territorio común presentó contrastes muy marcados. Aquellos que se identificaban con un tipo de relación de cultivo de la tierra favorecieron la propiedad privada sobre la pública. Para los entrevistados con una relación de tipo integrado con la naturaleza, la libertad de movimiento fue uno de los valores esenciales. Algunos de los entrevistados identificados con el uso de los recursos y con relaciones intelectuales y estéticas con la naturaleza, valoraron también de manera positiva la tierra como bien común. La aproximación utilizada en este estudio transforma las nociones polarizadas y dicotómicas en gradientes de perspectivas relacionadas a diferentes grados de ambientes ecológicos y culturales, locales y globales. La visión híbrida resultante de las perspectivas acerca de la naturaleza puede ser de utilidad en tiempos de cambio global, donde tanto escalas locales como globales contribuyen a identificar problemáticas asimétricas específicas, como también oportunidades de comunicación entre los diferentes grupos socioculturales.

Autism provides a model for exploring the nature of self‐consciousness: self‐consciousness requires the ability to reflect on mental states, and autism is a disorder with a specific impairment in the neurocognitive mechanism underlying this ability. Experimental studies of normal and abnormal development suggest that the abilities to attribute mental states to self and to others are closely related. Thus inability to pass standard ‘theory of mind’ tests, which refer to others’ false beliefs, may imply lack of self‐consciousness. Individuals who persistently (...) fail these tests may, in the extreme, be unable to reflect on their intentions or to anticipate their own actions. In contrast, individuals with high‐functioning autism or Asperger syndrome often possess a late‐acquired, explicit theory of mind, which appears to be the result of effortful learning. An experimental study with three people with Asperger syndrome suggested that level of performance on standard theory of mind tasks was strongly related to the ability to engage in introspection. Qualitative differences in the introspections of high‐functioning people with autism are also reflected in autobiographical accounts which may give a glimpse of what it is like to be autistic.

Corresponding to our best physical theories and going against our intuitions the term now is not related to events in the world in a direct way. This knowledge is supported by modern neurobiological investigations. The neurobiological conception of now is compared with the analysis of concepts concerning this issue. The conception turns out to be highly compatible with this analysis. In the last section of the paper I will argue for a considerable link between the notion of truth and the (...) notion of nowness in view of the meta-structure of now. German In Übereinstimmung mit unseren besten physikalischen Theorien und entgegen unserer Intuition bezieht sich der Ausdruck jetzt nicht unmittelbar auf Ereignisse in der Welt - diese Erkenntnis lässt sich durch die neuere neurobiologische Forschung untermauern. Das neurobiologische Zeitkonzept wird sprachphilosophischen Analysen zu diesem Thema gegenübergestellt; es erweist sich mit ihnen als recht gut vereinbar. Im letzten Teil des Beitrags argumentiere ich im Hinblick auf die Metastruktur von jetzt für eine bedeutsame Verbindungslinie zwischen dem Wahrheits-und dem Gegenwärtigkeitsbegriff. (shrink)

We challenge the notion that differences in spatial ability are the best or only explanation for observed sex differences in mathematical word problems. We suggest two ideas from the study of autism: sex differences in theory of mind and in central coherence.

In this paper, we attempt to make a distinction between egocentrism and allocentrism in social cognition, based on the distinction that is made in visuo-spatial perception. We propose that it makes a difference to mentalizing whether the other person can be understood using an egocentric (‘‘you'') or an allocentric (‘‘he/ she/they'') stance. Within an egocentric stance, the other person is represented in relation to the self. By contrast, within an allocentric stance, the existence or mental state of the other person (...) needs to be represented as independent from the self. We suggest here that people with Asperger syndrome suffer from a disconnection between a strong naı¨ve egocentric stance and a highly abstract allocentric stance. We argue that the currently used distinction between first-person and third-person perspective-taking is orthogonal to the distinction between an egocentric and an allocentric stance and therefore cannot serve as a critical test of allocentrism.

Autism: Mind and Brain provides a comprehensive overview of the latest research on autism and highlights new techniques that will progress future understanding. With contributions from leaders in autism research, the book describes the latest advances, discusses ways forward for future research, and presents new techniques for understanding this complex disorder.

This commentary cites several findings of neuromuscular research that are consistent with aspects of Plamondon's kinematic theory. In addition, we point out certain biomechanical properties of the limb that influence the requirements for the production of accurate movement, and might thus compromise the global applicability of any law governing speed/accuracy trade-offs.

This commentary examines Glenberg's characterization of “suppression” in light of negative priming and related phenomena. After offering a radically different slant on suppression, an attempt is made to weave this alternative version into Glenberg's provocative discussion of embodied memories.

Governments and local administrations increasingly use the internet to improve citizens’ participation in deliberation processes. However, research studies have pointed out that deliberation outcomes vary due to the participants’ sociodemographic differences. In this paper, we address this debate by quantitatively measuring different sociodemographic participant groups’ deliberation quality. By building an index of the quality of understanding, we analyze the quality of 1,991 postings on local political issues that participants contributed during the 2011 Zurich City debate. We defined five indicators for (...) deliberation quality: statement of reasons, proposals for solutions, respect, doubts, and reciprocity. The analysis confirms that the sociodemographic composition of the participants is of great importance for self-selected participation and deliberation quantity, but not for the deliberation quality.
