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...

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...

A small world (SW) is a (large) graph with both local clustering and, on average, short distances between nodes [1,2]. Short distances promote accessibility, whereas local clustering and redundancy of edges, as some research suggests [3,4], promotes robustness to disconnection and, through multiple independent pathways, reliable accessibility as well. For paths to transmit materials and informa...

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...

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...

Models of network formation emphasize the importance of social similarity and propinquity in producing strong interpersonal connections. The positive effect each factor can have on tie strength has been documented across a number of studies. And yet we know surprisingly very little about how the two factors combine to produce strong ties. Being in close proximity could either amplify or dampen ...

Scholars around the world have studied electronic word of mouth (eWOM) heavily in past decade. However, despite extensive knowledge effect eWOM on consumer behavior, there is still a lack understanding how source shapes those behaviors. There are many sources eWOM, influence which may different outcomes when it comes to consumers’ purchase intentions. Moreover, most studies measured social tie ...

We examine data on and models of small world properties and parameters of social networks. Our focus, on tie-strength, multilevel networks and searchability in strong-tie social networks, allows us to extend some of the questions and findings of recent research and the fit of small world models to sociological and anthropological data on human communities. We offer a ‘navigability of strong tie...

Arrays of subwavelength dipole bow-tie apertures are designed and characterized at terahertz frequencies. For an incident terahertz field perpendicular to the longer axis of the bow tie, a strong resonance enhancement, line narrowing, and a nonmonotonic frequency shift were observed with increasing length of the tapered bow-tie arms. Such characteristic behaviors primarily originate from locali...
