A subset D of V (G) is called an equitable dominating set of a graph G if for every v ∈ (V − D), there exists a vertex u ∈ D such that uv ∈ E(G) and |deg(u) − deg(v)| 6 1. The minimum cardinality of such a dominating set is denoted by γe(G) and is called equitable domination number of G. In this paper we introduce the equitable edge domination and equitable edge domatic number in a graph, exact...

An equitable risk allocation between contracting parties plays a vital role in enhancing the performance of the project. This research presents a new quantitative risk allocation approach by integrating fuzzy logic and bargaining game theory. Owing to the imprecise and uncertain nature of players’ payoffs at different risk allocation strategies, fuzzy logic is implemented to determine the value...

An empirical study of 350 tourists reveals that using non-media information sources for planning tourist trip influences expectations fulfillment. The use of non-media information sources also has a direct impact on the future use of media information sources for future tourist trip planning, as well as an indirect impact through expectations fulfillment. More specifically, the main determinant...

In many applications in sequencing and scheduling it is desirable to have an underlaying graph as equitably colored as possible. In this paper, we consider an equitable coloring of some corona products H G of two graphs G and H. In particular, we show that deciding the colorability of H G is NP-complete even if G is 4-regular and H is . 2 K Next, we prove exact values or upper bounds on the equ...

Let G = (V,E) be an undirected graph, where V is the set of vertices and E is that of edges. An equitable k-coloring of G is a partition of V into k disjoint stable subsets such that the difference on the cardinalities of any two subsets is at most one. Each subset is associated with a color and called a color set. The Equitable Coloring Problem (ECP) consists of finding the minimum value of k ...

In this paper, we examine how migrants‟ perceptions of psychological contract fulfillment affect their job performance. In addition, we also examine the mediating role of job involvement and moderating role of labor contract. Data were obtained from 305 employees from 14 construction companies in South China. Results reveal that: a) the psychological contract fulfillment is positively related w...

Previous studies on handicapping have suggested that in matches between 2 golfers, the better golfer has an advantage. In this paper, we consider medal play between 2 golfers when they are both playing well. The study uses the new slope system for handicapping. In this context we argue that it is actually the weaker golfer who has an advantage. The conclusions are based on both the analysis of ...

Indonesia's quality human development starts with Early Childhood Education (PAUD). PAUD has entered the stage of national standardization in 2015–2025. However, still faces problems participation and equitable access. This study aims to describe (1) how determine target candidates who are entitled receive SPM assistance, (2) proportion budget allocations for fulfilling which is responsibility ...
