Information quality assessment is the process of inspecting business information to ensure that it meets the needs of the knowledge workers who depend on it. We suggest in this paper that, prior to implementing a system to assess quality, those responsible for information quality can use a subset of clean data to create a statistical model of a decision(More)
Even though social networking sites are very popular all around the globe, social networks for professionals have not received much attention from the scientific community. We study how physicians interact with each other from the perspective of network analysis. In our study, we treat each physician as a node, and the link between them represents their(More)
This paper proposes an approach for comparing interlocked board networks over time to test for statistically significant change. In addition to contributing to the conversation about whether the Mizruchi hypothesis (that a disintegration of power is occurring within the corporate elite) holds or not, we propose novel methods to handle a longitudinal(More)
Biological thought increasingly recognizes the centrality of the genome in constituting and regulating processes ranging from cellular systems to ecology and evolution. In this paper, we ask whether genomics is similarly positioned as a core concept in the instructional sequence for undergraduate biology. Using quantitative methods, we analyzed the order in(More)
Several variations are given for an algorithm that generates random networks approximately respecting the probabilities given by any likelihood function, such as from a p * social network model. A novel use of the genetic algorithm is incorporated in these methods, which improves its applicability to the degenerate distributions that can arise with p *(More)
