Resumen: En el marco de la Teoría de Relevancia este trabajo analiza la coacción impuesta por los clasificadores nominales en chino y propone una estrategia para su traducción al español. Se llega a la conclusión de que la coacción impuesta por los clasificadores nominales en chino se produce en los casos metafóricos o metonímicos. En tales casos la discordancia surgida entre la semántica procedimental y la conceptual se resuelve siempre a favor de la procedimental. Por lo tanto, a la hora de traducir al español estos casos coactivos debemos acudir, ante todo, a la semántica procedimental de los clasificadores nominales y luego combinarla con los sentidos metafóricos o metonímicos que representan los sustantivos generados en los contextos coactivos para obtener una correcta traducción. Abstract: In the framework of Relevance Theory, this paper discusses the coercion cases imposed by nominal classifiers in Chinese and proposes a translation strategy. The results show that the coercion imposed by nominal classifiers in Chinese appears in the cases of metaphor or metonymy. In these cases, the conflict between procedural semantics and conceptual semantics is always resolved in favor of the procedural one. Therefore, when we translate them from Chinese to Spanish, to get a correct translation, we should find out firstly the procedural semantics of the nominal classifiers and then combine them with the metaphor or metonymy meaning of the nouns generated in coercion contexts.

This study explored and compared the perspectives of Taiwanese in-service and pre-service high school mathematics teachers regarding ideal teaching behaviours; the perspectives of a nationwide sample of students were taken as the baseline. Fourteen factors contributing to ideal teaching behaviours were identified through exploratory factor analyses. Nine factors, including idea explanation and speedy lecture, were rooted in traditional Chinese culture; five factors, including concrete representation and student activities, were influenced by Western cultures. Three teacher profiles were identified through k-means clustering analysis. The perspectives of in-service teachers were dominated by a painless meaning-emphasised profile; these teachers emphasised meaningful learning for students and avoided the fast pace and demanding requirements that can cause distress in students, whereas pre-service teachers were dominated by an all-round profile, revealing their openness to all factors. Compared with...

The coding mechanism of sensory memory on the neuron scale is one of the most important questions in neuroscience. We have put forward a quantitative neural network model, which is self-organized, self-similar, and self-adaptive, just like an ecosystem following Darwin's theory. According to this model, neural coding is a “mult-to-one”mapping from objects to neurons. And the whole cerebrum is a real-time statistical Turing Machine, with powerful representing and learning ability. This model can reconcile some important disputations, such as: temporal coding versus rate-based coding, grandmother cell versus population coding, and decay theory versus interference theory. And it has also provided explanations for some key questions such as memory consolidation, episodic memory, consciousness, and sentiment. Philosophical significance is indicated at last

The RecA family proteins mediate homologous recombination, a ubiquitous mechanism for repairing DNA double‐strand breaks (DSBs) and stalled replication forks. Members of this family include bacterial RecA, archaeal RadA and Rad51, and eukaryotic Rad51 and Dmc1. These proteins bind to single‐stranded DNA at a DSB site to form a presynaptic nucleoprotein filament, align this presynaptic filament with homologous sequences in another double‐stranded DNA segment, promote DNA strand exchange and then dissociate. It was generally accepted that RecA family proteins function throughout their catalytic cycles as right‐handed helical filaments with six protomers per helical turn. However, we recently reported that archaeal RadA proteins can also form an extended right‐handed filament with three monomers per helical turn and a left‐handed protein filament with four monomers per helical turn. Subsequent structural and functional analyses suggest that RecA family protein filaments, similar to the F1‐ATPase rotary motor, perform ATP‐dependent clockwise axial rotation during their catalytic cycles. This new hypothesis has opened a new avenue for understanding the molecular mechanism of RecA family proteins in homologous recombination. BioEssays 30:48–56, 2008. © 2007 Wiley Periodicals, Inc.
