The purpose of this paper is to explore the foundations of a general theory of technical culture, based on the notion of technical system and on the scientific concept of culture. To this end, several basic notions of the philosophy of technique, as technique, technology and technical system, are defined. Then, a distinction is proposed between cultural elements embodied in technical systems, and elements of technical culture which are not embodied in technical systems. Finally, a general view of the impact (...) of cultural factors in technical change is drawn. (shrink)

Based on research on the increasingly popular unconscious thought effect (UTE), it has been suggested that physicians might make better diagnostic decisions after a period of distraction than after an equivalent amount of time of conscious deliberation. However, published attempts to demonstrate the UTE in medical decision making have yielded inconsistent results. In the present study, we report the results of a meta-analysis of all the available evidence on the UTE in medical decisions made by expert and novice clinicians. The (...) meta-analysis failed to find a significant contribution of unconscious thought to the accuracy of medical decisions. This result cannot be easily attributed to any of the potential moderators of the UTE that have been discussed in the literature. Furthermore, a Bayes Factor analysis shows that most experimental conditions provide positive support for the null hypothesis, suggesting that these null results do not reflect a simple lack of statistical power. We suggest ways in which new studies could usefully provide further evidence on the UTE. Unless future research shows otherwise, the recommendation of using unconscious thought to improve medical decisions lacks empirical support. (shrink)

Este trabajo se ocupa de tres aspectos principales de la filosofía del lenguaje de Wittgenstein: la teoría de la forma lógica, la teoría de los objetos del Tractatus y la crítica la teoría de los sense-data. Las tesis de Wittgenstein se compararán con el pensamiento de Leonardo Polo y, especialmente, con algunas afirmaciones de Polo en torno al nominalismo, la constitución de un lenguaje trascendental y el concepto de conocimiento en Wittgenstein.

Higher plants must undergo a major developmental switch, the transition to flowering, if they are to successfully complete their life cycle. In many plants, the crucial decision of when to begin to produce flowers is primarily controlled by environmental signals. The process of floral induction involves the integration of the activities of two types of genes: those that control flowering time as a response to the environment as well as an endogenous clock, and those that determine the floral identity of (...) the cells. The first direct link between these two classes of genes has now been demonstrated(1). Forced expression of CONSTANS, a flowering‐time gene, promotes flowering through the transcriptional activation of LEAFY, a flower‐meristem‐identity gene. (shrink)
