Purpose – The purpose of this paper is to use generational cohort and professionalism theories as the framework to examine the interaction between supervisor-subordinate relationships, work-family conflict, discretionary power and affective commitment at the work-life interface for Northeast Brazilian public sector professional nurses. Design/methodology/approach – Quantitative data were collec...

A More Sums Than Differences (MSTD, or sum-dominant) set is a finite set A ⊂ Z such that |A+A| < |A−A|. Though it was believed that the percentage of subsets of {0, . . . , n} that are sum-dominant tends to zero, in 2006 Martin and O’Bryant [MO] proved that a positive percentage are sum-dominant. We generalize their result to the many different ways of taking sums and differences of a set. We p...

Digital divide can be considered a macro economical index representing the social differences and the separation between the North and the South of the world. Since the first definition of digital divide, it has been shown that it is also a great and unrecognized problem in the developed countries, especially in the field of education. “Digital disconnection” is a key problem for School and Uni...

In order to deal with constrained multi-objective optimization problems (CMOPs), a novel constrained multi-objective particle swarm optimization (CMOPSO) algorithm is proposed based on an adaptive penalty technique and a normalized non-dominated sorting technique. The former technique is utilized to optimize constrained individuals in each generation to obtain new objective functions, while the...

Inverted Generational Distance (IGD) has been widely considered as a reliable performance indicator to concurrently quantify the convergence and diversity of multiand manyobjective evolutionary algorithms. In this paper, an IGD indicatorbased evolutionary algorithm for solving many-objective optimization problems (MaOPs) has been proposed. Specifically, the IGD indicator is employed in each gen...

Phenological patterns of flowering and fruiting can be influenced by the effects of reproductive time on seed production. We propose here that these patterns are also influenced by phenological effects on offspring quality. Furthermore, we hypothesize that there are cross-generational trade-offs between parental and offspring components of parental fitness influencing the evolution of reproduct...
