Given a Brouwerian complete lattice (L,≤) and two referential sets K and E, and using a fuzzy relation R ∈ L which is reflexive and symmetric, certain fuzzy relations Ĥ ∈ L are characterized as solutions of X C R = X. These solutions Ĥ can be determinated by means of the L-fuzzy concepts associated with the K-labeled L-fuzzy context (L,K,E,E,R).

LaTaT is a Language and Text Analysis Toolset. This paper gives a brief description of the components comprising LaTaT, including a Minimalist parser and language and concept learning programs.

The 'self' is increasingly used as a variable in cognitive experiments and correlated with activity in particular areas in the brain. At first glance, this seems to transform the self from an ephemeral theoretical entity to something concrete and measurable. However, the transformation is by no means unproblematic. We trace the development of two important experimental paradigms in the study of...

This study investigated longitudinal predictors of proactive goals and activity participation at age 80 among members of the Terman Study of the Gifted. The participants were 242 individuals between the ages of 75 and 84 (M = 79.53) who responded to questionnaires in 1992, 1972, and 1950. Proactive goals included goals for involvement and achievement. Activity participation included intellectua...

The relationship between academic self-concept and academic achievement of Chicano(a) and/or Mexican American students at Colorado State University was investigated in this study. The participants included 114 undergraduate, full-time students who self-identify as Chicano(a) and/or Mexican American. The quantitative instrument utilized to measure academic self-concept was developed by Reynolds,...

Katsaras 1 defined a fuzzy norm on a vector space to construct a fuzzy vector topological structure on the space. Some mathematicians have defined fuzzy norms on a vector space from various points of view 2–4 . In particular, Bag and Samanta 5 , following Cheng and Mordeson 6 , gave an idea of fuzzy norm in such a manner that the corresponding fuzzy metric is of Kramosil and Michálek type 7 . T...

In order to improve students' teaching/learning processes computational systems have been developed allowing to adapt virtual courses based on the students' profiles. There are currently various kinds of adaptation such as instruccional adaptation of plans, assessments adaptation, and adaptation of educational contents, among others.The aim of this paper is to propose a fuzzy inference model fo...
