量(Quantities)は、あらゆる場面で用いられ、我々が世界を理解するために重要な一部で ある。エンジンの馬力、サイズ、走行距離、自動車の価格など、様々な量について私たち は会話を行っている。 この論文では、それらの表現を生成する、認知的な量および法則の象徴的表現(symbolic representations)を提案する。言語学と心理学の分野から証拠を集めた結果、その表象は 2 種類に分けることが出来ると主張する。 ・Dimensional representations 「大きい」や「小さい」など、量の変化を意味するもの ・Structural representations 「沸点」や「貧困線」など、質の変化を意味するもの そこで、パイロット実験を行った結果、Dimensional な区別に関して、人々に共通する 特徴が存在することが示唆された。 また最後に、我々は計算モ...

We have recently shown that 1) the infomax principle for the organization of perceptual systems leads to visual recognition architectures that are nearly optimal in the minimum Bayes error sense, and 2) a quantity which plays an important role in infomax solutions is the marginal diversity(MD): the average distance between the classconditional density of each feature and their mean. Since MD is...

background and objectives: this study was undertaken to determine the relationship between food security and individual dietary diversity score (idds). materials and methods: this population-based cross-sectional study was conducted on 200 non-diabetic individuals aged ≥40 years, selected randomly from the tehran lipid and glucose study. household food security was measured using a validated un...

investigating species diversity and richness is essential for defining conservation priorities. in addition, determining landscape parameters influencing species diversity and richness is important for selecting and designing parks and protected areas. kohgiluyeh & boyer ahmad province is a mountainous region, comprises hills, mounds, forests and plains. this vast province has high species dive...

The stress-gradient hypothesis predicts a higher frequency of facilitative interactions as resource limitation increases. Under severe resource limitation, it has been suggested that facilitation may revert to competition, and identifying the presence as well as determining the magnitude of this shift is important for predicting the effect of climate change on biodiversity and plant community d...

This paper assesses the congruence between the initiatives for regulatory reform known as ‘better regulation’ and the recently re-formulated ‘growth and jobs’ Lisbon agenda of the European Union. To do that, better regulation is re-conceptualised as metaregulation sets of rules on the process of rule-formulation, adoption, implementation, and evaluation. Meta-regulation has both structural and ...

The importance of allochthonous carbon to the productivity of stream ecosystems in temperate ecozones is well understood, but this relationship is less established in oligotrophic lakes. The nearshore littoral zones, at the interface of terrestrial and aquatic systems, are areas where the influence of terrestrial subsidies is likely greatest. We investigated the response of nearshore communitie...

The use of cryo-techniques in macromolecular crystallography has increased enormously over the last eight years and has become a vital part of modern X-ray data-collection methods. This paper presents some reasons for the rise in popularity of cryo-techniques and a brief outline of the basic methods, followed by a detailed discussion of factors to be considered when trying to optimize both the ...
