People experience pain when they spend money. Because previous studies have shown that perceived social support reduces physical pain, this research examined whether perceived social support reduces spending pain. Our studies showed that both real and recalled social support reduced spending pain (Studies 1-3) and that perceived social support reduced the perceived importance of money as a protection mechanism, which in turn reduced spending pain (Studies 1 and 3). Moreover, the pain-buffering effect of social support was stronger for hedonic purchases than for utilitarian purchases (Study 2). This research broadens our understanding of the factors that enhance consumer experiences and the relationships among love, security, and pain.
Identifying nucleation pathway is important for understanding the kinetics of first-order phase transitions in natural systems. In the present work, we study nucleation pathway of the Ising model in homogeneous and heterogeneous networks using the forward flux sampling method, and find that the nucleation processes represent distinct features along pathways for different network topologies. For homogeneous networks, there always exists a dominant nucleating cluster to which relatively small clusters are attached gradually to form the critical nucleus. For heterogeneous ones, many small isolated nucleating clusters emerge at the early stage of the nucleation process, until suddenly they form the critical nucleus through a sharp merging process. Moreover, we also compare the nucleation pathways for different degree-mixing networks. By analyzing the properties of the nucleating clusters along the pathway, we show that the main reason behind the different routes is the heterogeneous character of the underlying networks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
