Class Play

Given a certain class  K1 of algebraic structures. We study a problem of finding a class  K2 of algebraic structures such that the class K1  is approximable into K2 with respect to various predicates by generalized characters from  K1 to K2. The problem of minimization of approximation is also considered. Some theorems related to the problem of constructing an approximation class are obtained. The problem in question is much more complicated and actual than the approximation problem we have been studying before (see [2]-[6]). The results of the description of the approximation class play an important role in studying the solvability problem of the predicate P in the class of semigroups K. In particular, if the approximation class consists of finite semigroups, then this problem is solved positively. Even more difficult is the problem of determining the necessary conditions that class  is an approximation class for a given class K.

Class Play

Abstract. Social withdrawal in children is a risk factor for maladjustment. The Revised Class Play (RCP; Masten, Morison, & Pelligrini, 1985 ) has often been used to identify children’s behavioral difficulties with peers. However, in previous studies the sensitive-isolated scale of the RCP appeared to measure a mixture of different types of withdrawal, including withdrawal from peers and exclusion by peers. In the present study the original RCP was modified to more clearly distinguish withdrawal from the peer group from behavior associated with exclusion by peers. Two studies in Dutch samples of 8–13-year-old children were conducted to examine the reliability and validity of this modified Revised Class Play. Both studies revealed three scales: Sociability-Leadership, Aggressive-Disruptive, and a third factor labeled Anxious-Withdrawn. Anxious-Withdrawn primarily reflected social reticence. Stability of the scales after two years was high. High scores on the Anxious-Withdrawn scale were best predicted by teacher ratings of timid and anxious behavior and by negative self-perceptions of social competence. The results support the reliability and validity of the modified RCP in a Dutch sample.

AbstractThis study focuses on the process of the gradual shaping of Czech national awareness in Moravia from the beginning of the nineteenth century onwards when the necessary conditions for the development of improved mutual relations between the Czech (Slavic) population in the two Lands of the Czech Crown -Bohemia and Moravia - were slowly being formed. Moravia faced a number of handicaps to the development of a national revival in comparison with Bohemia, the most significant of which was the relatively high degree of Germanisation of the land. A change to the image of Moravia came in the revolutionary years 1848/1849, when Czech national awareness spread to broader sections of society in Moravia. The view of Bohemia held by the Moravians underwent significant change and a period of increasingly intensive political and cultural contact between the two lands arose.
