On positive-influence target-domination
Consider a graph G = (V, E) and a vertex subset A ⊆ V . A vertex v is positive-influence dominated by A if either v is in A or at least half the number of neighbors of v belong to A. For a target vertex subset S ⊆ V , a vertex subset A is a positive-influence target-dominating set for target set S if every vertex in S is positive-influence dominated by A. Given a graph G and a target vertex sub...
متن کاملDoes positive affect influence health?
This review highlights consistent patterns in the literature associating positive affect (PA) and physical health. However, it also raises serious conceptual and methodological reservations. Evidence suggests an association of trait PA and lower morbidity and of state and trait PA and decreased symptoms and pain. Trait PA is also associated with increased longevity among older community-dwellin...
متن کامل6-Sulphated Chondroitins Have a Positive Influence on Axonal Regeneration
Chondroitin sulphate proteoglycans (CSPGs) upregulated in the glial scar inhibit axon regeneration via their sulphated glycosaminoglycans (GAGs). Chondroitin 6-sulphotransferase-1 (C6ST-1) is upregulated after injury leading to an increase in 6-sulphated GAG. In this study, we ask if this increase in 6-sulphated GAG is responsible for the increased inhibition within the glial scar, or whether i...
متن کاملPositive Influence of Fragrances on Humans
as certain surfactants in cleaning products. Of course, fragrance is also used to mask biological malodors such as those produced in the scalp and underarm area. Fragrance materials themselves have benefits outside their use in fragrance. For example, extensive research suggests that some fragrance chemicals, particularly monoterpenes, have effective anticancer and other pharmacological propert...
متن کاملThe Dark Side of Positive Social Influence
Social influence in the form of social norms has been widely used to transform behaviors, and is argued to be especially efficacious in the context of health related activities. However, can such externally induced compliance produce negative outcomes? When individuals feel compelled to conform to the behavior of the majority, does it lead to an unexpected backfire effect? We conducted a random...
