a comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولCompact Factors in Finally Compact Products of Topological Spaces
We present instances of the following phenomenon: if a product of topological spaces satisfies some given compactness property then the factors satisfy a stronger compactness property, except possibly for a small number of factors. The first known result of this kind, a consequence of a theorem by A. H. Stone, asserts that if a product is regular and Lindelöf then all but at most countably many...
متن کاملProperties of Dμ-Compact Spaces in Generalized Topological Spaces
The aim of this paper is to introduce a further generalization of compactness in generalized topological spaces. We define and study the concept of Dμ-compact spaces in generalized topological spaces. A space(X, μ) is Dμ-compact if every Dμ-cover of X has a finite Dμ-sub cover. Basic properties and characterizations of Dμ-compact space are established. Dμ-compactness in subspaces, products of g...
متن کاملQuasi-compact Operators in Topological Linear Spaces
The classical theorems of Riesz [l] on compact operators have been extended by Leray [2] and Williamson [3] to the context of topological linear spaces. Ringrose [4] has shown that if an operator on such a space is compact, the square of its adjoint is also compact, where the topology on the dual space is that of uniform convergence on bounded sets. Thus if an operator is continuous and some po...
متن کاملON THE SHARP FOURIER TYPE OF Lp WITH RESPECT TO COMPACT TOPOLOGICAL GROUPS
The sharp Fourier type of Lp with respect to a non-commutative compact group was partially solved in a recent paper of J. Garćıa-Cuerva, J.M. Marco and the author. After that, the complete solution (without exact constants) has been given in a paper of M. Junge and the author by using techniques of non-commutative probability. We give an elementary solution to this problem using basic tools fro...
