Influencing Network Graph Perception and Judgment: Effects of Direct Connections, Base Rates, and Visual Layout Proximity on Social Network Analysis
نویسندگان
چکیده
Social network graphs are often used to help inform judgments in a variety of domains, such as public health, law enforcement, and political science. Across two studies, we examined how graph features influenced probabilistic judgments in graph-based social network analysis and identified multiple heuristics that participants used to inform these judgments. Study 1 demonstrated that participants’ judgments were influenced by information about direct connections, base rates, and layout proximity, and participants’ self-reported strategies also reflected use of this information. Study 2 replicated findings from Study 1 and provided additional insight into the hierarchical ordering of these strategies and the decision process underlying judgments from social network graphs.

In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...
متن کاملCliques Role in Organizational Reputational Influence: A Social Network Analysis
Empirical support for the assumption that cliques are major determinants of reputational influence derives largely from the frequent finding that organizations which claimed that their cliques’ connections are influential had an increased likelihood of becoming influential themselves. It is suggested that the strong and consistent connection in cliques is at least partially responsible for the ...

Network of connections is an informal institution, which affects agents’ decisions as well as their outcomes. Dominant neoclassical paradigm has neglected the role of connections and links, due to its atomistic view, while social networks can play a crucial role with regards to economic and social phenomena, such as migration, job finding, crime network, learning, financial crisis contagion, mi...

A more sophisticated understanding of the unpredictable, disorderly and unstable aspects of healthcare organisations is developing in the knowledge translation (KT) literature. In an article published in this journal, Kitson et al introduced a new model for KT in healthcare based on complexity theory. The Knowledge Translation Complexity Network Model (KTCNM) provides a fresh perspective by mak...
