What do all languages have in common, and what gives each language its individuality? Language typology, which has developed in response to these fundamental questions, is concerned with the construction of theoretical frameworks capable of delimiting the range of possible human languages and of capturing constraints on cross-linguistic variation. Language typology is a major concern of all contemporary schools of linguistics, yet a coherent image of the field is difficult to form because of the diversity of theoretical orientations and practical (...) methodologies. This collection brings together for the first time original contributions from major schools of typological research, from the Prague School to the Generative Grammar tradition. Leading scholars offer first-hand accounts of the theoretical foundations and substantive findings of their particular school of thought, clarifying basic assumptions which are often not explicitly stated in the literature. The collection as a whole provices both a survey of the place of individual typological schools in the historiography of the subject and a comprehensive account of the present state of language typology in an international context. It gives an overview of both the underlying unity of and the differences in the methods employed in the field. (shrink)

The lexicalist vs. transformationalist controversy involving causative sentences has been argued to the extreme extent in either position, studies based on Fillmore's case grammar by Sasaki and Taylor representing the former, and those based on the theory of lexical decomposition by McCawley and G. Lakoff representing the latter. The following work presents arguments that neither of these extreme positions is correct in Japanese. Different types of evidence are presented for the position that derives the lexical causative, e.g., koros 'kill', lexically (...) and the affixal causative, e.g., sin-ase 'cause to die', transformationally.

Spontaneous actions are preceded by brain signals that may sometimes be detected hundreds of milliseconds in advance of a subject's conscious intention to act. These signals have been claimed to reflect prior unconscious decisions, raising doubts about the causal role of conscious will. Murakami et al. (2014. Nat Neurosci 17: 1574–1582) have recently argued for a different interpretation. During a task in which rats spontaneously decided when to abort waiting, the authors recorded neurons in the secondary motor cortex. The neural (...) activity and relationship to action timing was parsimoniously explained using an integration-to-bound model, similar to those widely used to account for evidence-based decisions. In this model, the brain accumulates spontaneously occurring inputs voting for or against an action, but only commits to act once a certain threshold is crossed. The model explains how spontaneous decisions can be forecast (partially predicted) by neurons that reflect either the input or output of the integrator. It therefore presents an explicit hypothesis capable of rejecting the claim that such predictive signals imply unconscious decisions. We suggest that these results can inform the current debate on free will but must be considered with caution. (shrink)

Genetic Algorithms(GAs) are effective approximation algorithms which focus on “hopeful area” in the searching process. However, in harder problems, it is often very difficult to maintain a favorable trade-off between exploitation and exploration. All individuals leave the big-valley including the global optimum, and concentrate on another big-valley including a local optimum often. In this paper, we define such a situation on conventional GAs as the “UV-phenomenon”, and suggest UV-structures as hard landscape structures that will cause the UV-phenomenon. We introduce a (...) test function which has explicit UV-structures, and show UV-phenomenon caused by them. Next we analyze Fletcher and Powell function to confirm our hypothesis. Finally we propose a novel framework of GAs which can cope with UV-structures. (shrink)
