The study reported here examines characteristics of weak-tie support network preference among members of health-related computer-mediated support groups. Drawing on weak-tie support network theory and socioemotional selectivity theory, participants’ age and health condition were assessed as predictors of weak ties support network preference. Relationships between the dimensions of weak-tie supp...

Cluster supply chain (CSC) is a special kind of enterprise network with double feature of cluster and supply chain and is an important channel for enterprises close to the knowledge, resources, markets, and technologies. Cluster supply chain has special network structure and network relational which are different from general cluster and supply chain. In a particular industry cluster region, al...

Previous research has shown that spending money on others (prosocial spending) increases happiness. But, do the happiness gains depend on who the money is spent on? Sociologists have distinguished between strong ties with close friends and family and weak ties--relationships characterized by less frequent contact, lower emotional intensity, and limited intimacy. We randomly assigned participant...

This article argues that consideration of the strength of ties between communicators can help reconcile disparate results on the impact of new media on social relations. It is argued from the research literature and studies by the author that where ties are strong, communicators can in uence each other to adapt and expand their use of media to support the exchanges important to their tie, but ...

Previous studies on review information adoption, drawing upon dual process theory, focus on the important roles of two key review-related factors namely argument strength and source credibility, but pay less attention to the social relationships between review sources and recipients. To fill this research gap, based on the construal level theory, we articulate that tie strength moderates the im...

Although agriculture has a major role in economy, in general, and employment opportunities for unemployed population,in particular, limited ability of individuals to recognize entrepreneurial opportunities in agriculture has reduced the share ofagriculture in employment. Therefore, the enhancement of opportunity recognition skills among individuals in the agriculture sector is believed to solve...

Social networks are important for finding jobs, but which ties are most useful? Granovetter (1973) suggested that “weak ties” are more valuable than “strong ties,” since strong ties have redundant information, while weak ties have new information. Using six million Facebook users’ data we find evidence for the opposite. We proxy for job help by identifying people who eventually work with a pre-...

We have recently cloned a novel human receptor tyrosine kinase, tie, from human leukemia cells showing megakaryoblastoid differentiation. We report here that the 4.4-kb tie messenger RNA (mRNA) is present in all human fetal and mouse embryonic tissues. By in situ hybridization, the tie mRNA was localized to the endothelia of blood vessels and endocardium of 9.5- to 18.5-day mouse embryos. Howev...
