It is well known that any bipartite (social) network can be regarded as a formal context (G,M, I). Therefore, such networks give raise to formal concept lattices which can be investigated utilizing the toolset of Formal Concept Analysis (FCA). In particular, the notion of clones in closure systems on M , i. e., pairwise interchangeable attributes that leave the closure system unchanged, suggest...

As part of a larger study of student understanding of concepts in linear algebra, we interviewed 10 university linear algebra students as to their conceptions of functions from high school algebra and linear transformation from their study of linear algebra. An overarching goal of this study was to examine how linear algebra students see linear transformation as related to high school function....

The quantity-quality debate in social sciences also concerns concept formation and operationalization. The first approach has strong naturalist assumptions, while the second one focuses on the historical specificity of concepts. The solution to overcome this divide would be finding a path which balances the two perspectives. In this article we argue that fuzzy set theory can be a helpful tool f...

On the received view, the Representational Theory of Measurement reduces measurement to the numerical representation of empirical relations. This account of measurement has been widely criticised. In this paper, I provide a new interpretation of the Representational Theory of Measurement that sidesteps these debates. I propose to view the Representational Theory of Measurement as a library of t...

social capital is a new concept that’s been important in management literature in recent years. the importance of this concept has led to increase the researchers’ trends to develop models and diagnose new indexes. the main object of this research is exploring and designing a model to achieve foregoing goal. social capital development in universities and higher education centers as fundamental ...
