The paper is conceived as a first study on the Suszko operator. The purpose of this paper is to indicate the existence of close relations holding between the properties of the Suszko operator and the structural properties of the model class for various sentential logics. The emphasis is put on generality both of the results and methods of tackling the problems that arise in the theory of this operator. The attempt is made here to develop the theory for non-protoalgebraic logics. 相似文献
A semantics may be compositional and yet partial, in the sense that not all well-formed expressions are assigned meanings by it. Examples come from both natural and formal languages. When can such a semantics be extended to a total one, preserving compositionality? This sort of extension problem was formulated by Hodges, and solved there in a particular case, in which the total extension respects a precise version of the fregean dictum that the meaning of an expression is the contribution it makes to the meanings of complex phrases of which it is a part. Hodges' result presupposes the so-called Husserl property, which says roughly that synonymous expressions must have the same category. Here I solve a different version of the compositional extension problem, corresponding to another type of linguistic situation in which we only have a partial semantics, and without assuming the Husserl property. I also briefly compare Hodges' framework for grammars in terms of partial algebras with more familiar ones, going back to Montague, which use many-sorted algebras instead.
Theoretical gaps of the cognitive science. First of all the gap-thesis is based on a criticism 1. of the computer-orientated
cognitive science (it confuses information with the information carrier), 2. of connectivism (its linguistic borrowing from
the neurobiology is not appropriate), 3. of Varelas production model (the elimination of the function of representation results
in the loss of the cognitive ability). From the context of meaning and time, then the author sketches a cognitive theoretical
approach, in which thinking as a (symbolic and/or subsymbolic) representation of meaning is introduced, which develops in
a three-digit relation between world, language and substrate on the basis of isomorphy of time.

To date, little research has investigated the antecedents and implications of salespersons' identification with the brands and the companies they represent. As the nature of the selling job is unique from other inside employee positions, with increased independence of the firm and loyalty that may be expanded to the customers rather than the firm itself, an investigation of this phenomenon within the sales context holds significant implication for sales force management. The salesperson also represents an extension of the marketing communication programme of the firm and thus has direct bearing on how the company and brand image are communicated to the customer. Therefore, the purpose of our paper is to hypothesize and empirically test the notion that higher levels of perceived congruence between a salesperson's own values and those values of the brand and company he or she represents will lead to higher brand identification and company identification which in turn should create higher job satisfaction, commitment and performance. We discuss our results and offer practical insights to sales managers. Further, we discuss limitations of our study and provide directions for future research. 相似文献
Abstract The rôle of dislocations with Burgers vectors, b, given by b = [0001] during deformation of samples of the intermetallic compound Ti3Al has been assessed. At room temperature, the experimental evidence is consistent with these dislocations being sessile, their density and morphology being similar to that in undeformed samples. In samples deformed at 650°C and above, it is concluded that motion of these dislocations is effected by dislocation climb. The line directions of the various segments of dislocations with b= [0001] are shown to be perpendicular to planes that contain sheets of Ti atoms, with an expected tendency to exhibit a high Peierls stress. 相似文献
