In classes of algebras such as lattices, groups, and rings, there are finite algebras which individually generate quasivarieties which are not finitely axiomatizable (see [2], [3], [8]). We show here that this kind of algebras also exist in Heyting algebras as well as in topological Boolean algebras. Moreover, we show that the lattice join of two finitely axiomatizable quasivarieties, each generated by a finite Heyting or topological Boolean algebra, respectively, need not be finitely axiomatizable. Finally, we solve problem 4 asked in Rautenberg [10]. 相似文献

In three studies, we examined the role task rules play in multitasking performance. We postulated that rules should be especially important for individuals highly motivated to have structure and clear answers, i.e., those high on need for cognitive closure (NFC). High NFC should thus be related to greater compliance with task rules. Specifically, given high goal importance, NFC should be more strongly related to a multitasking strategy when multitasking is imposed by the rules, and to a mono-tasking strategy when monotasking is imposed by the rules. This should translate into better multitasking or mono-tasking performance, depending on condition. Overall, the results were supportive as NFC was related to a more mono-tasking strategy in the mono-tasking condition (Studies 1 and 2 only) and more dual-tasking strategy in the dual-tasking condition (Studies 1–3). This translated into respective differences in performance. The effects were significant only when goal importance was high (Study 1) and held when cognitive ability was controlled for (Study 2). 相似文献

This study aimed to investigate antecedents of positive perceptions of divine agents and the optimistic assumption that the world is meaningful, basically good and trustworthy, as found in Polish men and women who struggle with homelessness or alcohol addiction. In the largely understudied groups of people who were homeless (n = 111) or alcohol addicted (n = 120), we confirmed that communal orientation is a consistent precursor of beliefs in supernatural agents such as God, the Devil and angels, as well as positive perceptions of both God and guardian angels. The antecedents of basic trust varied across participant groups. However, among them were positive attitudes toward God, communal orientation, and a deferring problem-solving style. Additionally, we found asymmetric links between perceptions of divine agents and both duration of addiction and duration of therapy in the addicted group. The former was related to a less positive perception of guardian angels and less perceived collaboration with God, whereas the latter was linked to a more positive perception of angels and more collaboration with God in problem-solving. We discuss the significance of a positive concept of divine beings for people who are homeless or alcohol addicted. 相似文献
