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-...

Abstract The proximity literature usually treats in terms of common attributes shared by agents, disregarding the relative position an actor inside network. This paper discusses importance such dimension proximity, labelled as in-network and proposes empirical measurement for it, assessing its impact (jointly with other dimensions proximity) on creation strong knowledge network ties ICT region ...

BACKGROUND An intact angiopoietin/Tie-2 ligand receptor system is indispensable for life. High circulating angiopoietin-2 (Ang-2) concentrations are strongly associated with kidney disease involving the progressive loss of glomerular filtration. The aim of our study was to investigate the associations between renal function and serum Ang-2 or serum Tie-2 concentrations in the general population...

On Facebook, users are exposed to posts from both strong and weak ties. Even though several studies have examined the emotional consequences of using Facebook, less attention has been paid to the role of tie strength. This paper aims to explore the emotional outcomes of reading a post on Facebook and examine the role of tie strength in predicting happiness and envy. Two studies - one correlatio...

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 ...

Based on more than 14 months' ethnographic research in China, this article brings in culture and symbolic interactionism to understand the social embeddedness of economic transactions. First, an analytic frame linking tie strengths to defining principles, relational properties, and interactions is constructed and applied to changes in life insurance transactions in China. The data suggest that ...

Many clustering algorithms are in favour of node-based methods, but a link between nodes has one single feature, so link-based is sometimes easier than methods. Being dependent on the characteristics links, detection algorithm for non-overlapping community put forward this paper. The method proposed also distinguishes differences with high degree accuracy and detects communities minimal number ...

Who talks with whom in national policymaking? How do lobbyists allocate their social resources to best receive information? And how does network position condition which lobbyists get access? We analyze communication networks among lobbyists and government actors in national politics. We begin by wedding rational choice models to network analysis with a formal analysis of lobbyists’ choice of c...

We propose and test a novel approach to the dilemma that the very networkbridging structure most likely to provide access to novel knowledge may be illsuited for the cooperation needed to successfully transfer that knowledge. We theorize that the relational dimension of social capital (e.g., tie strength) can act as a substitute for the structural benefits of network closure, and so a networkbr...
