The article is mainly concernedwith the Kruskal tree theorem and the following observation: there is a duality at the level of binary relations between well and noetherian orders. The first step here is to extend Kruskal theorem from orders to binary relations so that the duality applies. Then, we describe the theorem obtained by duality and show that it corresponds to a theorem by Ferreira and...

Precis: There are many ways of studying the effects of protection on the industrial structure and trade flows of the protected economy. In this paper, we do so by comparing certain features of the economies of Northern Ireland and the Republic of Ireland during the mid-'sixties. At that time, the Republic was a highly protected economy and consequently would be expected to be much less speciali...

The effects of the violations normality and homogeneity variances assumptions on power one-way ANOVA F-test is studied in this paper. Simulation experiments were conducted to compare parametric with non-parametric Kruskal‒Wallis (KW) test normal/non-normal, equal/unequal scenarios sample group means. Each these 184 simulation was replicated N = 1000 times obtained for both F KW tests. Shapiro‒W...

The purpose of this study was to compare couples in different phases of marriage with the primary goal of contributing to our understanding of marital quality throughout the life span. Rusbult’s investment theory (Rusbult, 1980, 1983; Rusbult & Buunk, 1993), which predicts specific outcomes concerning relationship satisfaction, commitment, and stability, served as the guiding theory behind this...
