Developing categorization schemes involves discovering structures in the world that support a learner's goals. Existing models of category learning, such as ex emplar and prototype models, neglect the role of goals in shaping conceptual organization. Here, a clustering ap proach is discussed that reflects the joint influences of the environment and goals in directing category acquisition. Clust...

Crosslingual text classification consists of exploiting labeled documents in a source language to classify documents in a different target language. In addition to the evident translation problem, this task also faces some difficulties caused by the cultural discrepancies manifested in both languages by means of different topic distributions. Such discrepancies make the classifier unreliable fo...

The present study compared 5- and 10-year-old North American and Israeli children's beliefs about the objectivity of different categories (n = 109). Children saw picture triads composed of two exemplars of the same category (e.g., two women) and an exemplar of a contrasting category (e.g., a man). Children were asked whether it would be acceptable or wrong for people in a different country to c...

INTRODUCTION While the relationships among socio-economic status (SES) and obesity are powerful and synergistic, the SES construct is insufficient to describe some of the cultural influences on status production in society, and therefore on obesity production. Socio-economic status has two closely related dimensions. The economic one is represented by financial wealth while the social one can i...

I point out in this paper that the inscription ‘art’ is a homonym. Primarily, it names the category of memetic innovation, illustrations of which are encountered in every cultural domain. Thus, art may be—but is not necessarily—encountered in the artworld, where the makers of works of art use a different word with the same spelling to name a class of artefacts. I explain memetic innovation and ...

‎In this paper first we define the morphism between geometric spaces in two different types‎. ‎We construct two categories of $uu$ and $l$ from geometric spaces then investigate some properties of the two categories‎, ‎for instance $uu$ is topological‎. ‎The relation between hypergroups and geometric spaces is studied‎. ‎By constructing the category $qh$ of $H_{v}$-groups we answer the question...

We propose a synthesis of two lines of sociological research on boundary spanning in cultural production and consumption. One, research on cultural omnivorousness, analyzes choice by heterogeneous audiences facing an array of crisp cultural offerings. The other, research on categories in markets, analyzes reactions by homogeneous audiences to objects that vary in the degree to which they confor...
