We construct a class K of algebras which are matrices of the logical system Z introduced in [4]. It is shown that algebras belonging to the class K are decomposable into disjoint subalgebras which are Boolean algebras.To the memory of Jerzy SupeckiTranslated From the Polish by Jan Zygmunt. 相似文献

This study sought to determine the relationship of sex and race as moderators of psychological availability on work engagement in various South African organisations. Participants were 1 059 employees predominantly from the corporate sector in Gauteng province (females = 61%, blacks = 36%). Cross-sectional survey data were collected from the employees using the Psychological Conditions Scale and the Utrecht Work Engagement Scale (UWES). Moderated hierarchical regression analyses tested the prediction of work engagement from psychological availability, while controlling for the sex and race of employees. Psychological availability increased the level of work engagement for both men and women, the relationship, however, was stronger for women as compared to men. White employees were less work engaged compared to other race group members. Psychological availability was higher for the black, Indian, and coloured employees compared to white employees. The results confirmed the positive relationship of psychological availability on work engagement, and that sex and race differences exist for employees in a developing country. 相似文献
