New Connectives for (Full) Fuzzy Resolution

Abstract: In this paper we study resolution truth functions for sound and complete evaluation of many valued resolution For modus ponens we give a formula for generation of this truth function using additive generator of underlying conjunctor In the case of full resolution we give a construction of resolution truth function and study its properties

Identification in Models with Discrete Variables

Abstract: This paper provides a novel, simple, and computationally tractable method for determining an identified set that can account for a broad set of economic models when the economic variables are discrete. Using this method, we show using a simple example how imperfect instruments affect the size of the identified set when the assumption of strict exogeneity is relaxed. This knowledge can be of great value, as it is interesting to know the extent to which the exogeneity assumption drives results, given it is often a matter of some controversy. Moreover, the flexibility obtained from our newly proposed method suggests that the determination of the identified set need no longer be application specific, with the analysis presenting a unifying framework that algorithmically approaches the question of identification.

Overtime Work Determinants of Men and Women in Slovakia

Abstract: The paper deals with the supply side of the Slovak labour market. The main goal of the present study was to examine what variables contribute to the explanation of working over-time (e.g. devoting more than 40 hours per week to paid work) separately for women and men. A binomial logistic regression was used and factors were identified separately for men and women. The data were drawn from the results of primary research conducted in the year 2018. Results suggest that the probability of working overtime is higher for both men and women with higher income. It seems that the substitution effect of an increase in income dominates the income effect. Household circumstances influence the probability of one’s working overtime. In those multi-member households where the husband has higher level of education than the wife, the husband will more likely work overtime and women will be less likely to work overtime. The presence of very young children in households has a significant impact on the reporting of women working overtime. Women with preschool children were less likely to work overtime than women in households in which there were older children or households without children.

On the Atanassov Concept of Fuzziness and One of Its Modification

Abstract: The family \(\mathcal F\) of intuitionistic fuzzy sets [1, 2, 3] is compared with the family \(\mathcal V\) of interval valued fuzzy sets. Since the spaces are isomorphic, from the measure theory on \(\mathcal F\) the measure theory on \(\mathcal V\) can be deduced. In the paper they are mentioned the state representation [7, 8, 44, 50], the inclusion—exclusion property [6, 22, 23] and the existence of invariant state [45].
