Multi-Level Opinion Dynamics Under Bounded Confidence, Gang Kou, Yiyi Zhao, Yi Peng, Yong Shi
Multi-Level Opinion Dynamics Under Bounded Confidence, Gang Kou, Yiyi Zhao, Yi Peng, Yong Shi
Information Systems and Quantitative Analysis Faculty Publications
Opinion dynamics focuses on the opinion evolution in a social community. Recently, some models of continuous opinion dynamics under bounded confidence were proposed by Deffuant and Krause, et al. In the literature, agents were generally assumed to have a homogeneous confidence level. This paper proposes an extended model for a group of agents with heterogeneous confidence levels. First, a social differentiation theory is introduced and a social group is divided into opinion subgroups with distinct confidence levels. Second, a multi-level heterogeneous opinion formation model is formulated under the framework of bounded confidence. Finally, computer simulations are conducted to study the …

Citizen science creates a nexus between science and education that, when coupled with emerging technologies, expands the frontiers of ecological research and public engagement. Using representative technologies and other examples, we examine the future of citizen science in terms of its research processes, program and participant cultures, and scientific communities. Future citizen‐science projects will likely be influenced by sociocultural issues related to new technologies and will continue to face practical programmatic challenges. We foresee networked, open science and the use of online computer/video gaming as important tools to engage non‐traditional audiences, and offer recommendations to help prepare project managers for …
A Multicriteria Decision Making Approach For Estimating The Number Of Clusters In A Data Set, Yi Peng, Yong Zhang, Gang Kou, Yong Shi
A Multicriteria Decision Making Approach For Estimating The Number Of Clusters In A Data Set, Yi Peng, Yong Zhang, Gang Kou, Yong Shi
Information Systems and Quantitative Analysis Faculty Publications
Determining the number of clusters in a data set is an essential yet difficult step in cluster analysis. Since this task involves more than one criterion, it can be modeled as a multiple criteria decision making (MCDM) problem. This paper proposes a multiple criteria decision making (MCDM)-based approach to estimate the number of clusters for a given data set. In this approach, MCDM methods consider different numbers of clusters as alternatives and the outputs of any clustering algorithm on validity measures as criteria. The proposed method is examined by an experimental study using three MCDM methods, the well-known clustering algorithm–k-means, …
Public Participation In Scientific Research: A Framework For Deliberate Design, Jennifer L. Shirk, Heidi L. Ballard, Candie C. Wilderman, Tina Phillips, Andrea Wiggins, Rebecca Jordan, Ellen Mccallie, Matthew Minarchek, Bruce V. Lewenstein, Marianne E. Krasny, Rick Bonney

Members of the public participate in scientific research in many different contexts, stemming from traditions as varied as participatory action research and citizen science. Particularly in conservation and natural resource management contexts, where research often addresses complex social–ecological questions, the emphasis on and nature of this participation can significantly affect both the way that projects are designed and the outcomes that projects achieve. We review and integrate recent work in these and other fields, which has converged such that we propose the term public participation in scientific research (PPSR) to discuss initiatives from diverse fields and traditions. We describe three …
A Systematic Method For Discovering Effective Patterns Of Virtual Project Management, Deepak Khazanchi, Ilze Zigurs
A Systematic Method For Discovering Effective Patterns Of Virtual Project Management, Deepak Khazanchi, Ilze Zigurs
Information Systems and Quantitative Analysis Faculty Publications
The effective management of virtual projects within global organizations is an inherently collaborative activity as well as an increasingly critical issue. The concept of patterns provides a useful theoretical framework by which we can study the design of effective practices for the management of virtual projects. However, a number of significant gaps exist in our knowledge of this area and one of the most important is the need for a systematic method for discovering effective patterns. We propose such a systematic method and provide a detailed example of the use of our proposed pattern discovery method.
