“Toward a better scientific collaboration success prediction model through the feature space expansion” published in the International Journal, Scientometrics

Toward a better scientific collaboration success prediction model through the feature space expansionby Fahimeh Ghasemian, Kamran Zamanifar, Nasser Ghasem-Aqaeeand Noshir Contractor were published in Scientometrics. The article highlights the problem with the prediction of scientific collaboration success based on the previous collaboration of scholars using machine learning techniques is addressed in this study. As the exploitation of collaboration network is essential in collaborator discovery systems, in this article an attempt is made to understand how to exploit the information embedded in collaboration networks. We benefit the link structure among the scholars and also among the scholars and the concepts to extract set of features that are correlated with the collaboration success and increase the prediction performance. The effect of considering other aggregate methods in addition to average and maximum, for computing the collaboration features based on the feature of the members is examined as well. A dataset extracted from Northwestern University’s SciVal Expert is used for evaluating the proposed approach. The results demonstrate the capability of the proposed collaboration features in order to increase the prediction performance in combination with the widely-used features like h-index and average citation counts. Consequently, the introduced features are appropriate to incorporate in collaborator discovery systems.

Noshir Contractor Gives Keynote Address at the University of Colorado, Denver’s 4th Annual Network Leadership Training Academy

Noshir Contractor gave the keynote address at the University of Colorado, Denver’s 4th Annual Network Leadership Training Academy, titled  “Building and Leveraging Powerful Social Networks”. Click here for a link to the event page.

Description:
The Network Leadership Training Academy (NLTA) is a place where network leaders gather to learn, share ideas, and develop skills for engaging in the “network way of working.” This 3-day workshop, hosted by the University of Colorado Denver’s Center on Collaborative Governance, is focused on building, managing, and evaluating effective networks. Many people today are deeply involved in the network way of working, but are struggling to find tools and a place to build skills and a community for this new way of connecting across boundaries. This interactive workshop is based on the premise that everyone involved in a network requires network leadership skills in order to be an active, effective member of a collaborative network. he agenda for the 2016 NLTA is packed full of opportunities for attendees to share and learn from each other’s experiences and skills, as well as research and tools to translate back to practice. Our keynote address on Building and Leveraging Powerful Social Networks features Dr. Noshir Contractor, Professor at Northwestern University and Director of the Science of Networks in Communities (SONIC) research center. He will share his work on investigating factors that lead to the formation, maintenance, and dissolution of dynamically linked social and knowledge networks in a wide variety of contexts. Large group sessions will be led by NLTA core trainers who are recognized for their contributions to network science research. Session topics include: · Managing Networks, Brint Milward, Ph.D, University of Arizona · Network Way of Working: Building a Network Culture, Janice Popp, MSW, RSW, University of Calgary · Affective Contagion in Networks: Evaluating Process Quality, Darrin Hicks, PhD, University of Denver · Evaluating Networks as Systems, Danielle Varda, PhD, University of Colorado Denver Other session topics include: Networks 101, Using PARTNER’s Social Network Analysis Tool to Evaluate your Networks, Networks as Policy Tools: “Network Nuggets” from Research and Practice, Facilitation Skills, Conflict Training, and Collective Impact.

SONIC Receives Yet Another NASA Grant!

Noshir Contractor along with collaborators Suzanne Bell (DePaul University) and Leslie DeChurch (currently at Georgia Tech, but soon to be at Northwestern University) have received another grant from the National Aeronautics and Space Administration in order to study the relationship between composition, interpersonal relations, and team effectiveness in space crews. This project will be jointly conducted with researchers at Institute of Biomedical Problems, whose research informs operations for the Russian Federal Space Agency. In this US-Russian collaboration, researchers will utilize data previously collected in the Mars 105 and Mars 500 simulations; collect new data using analog-definition research in the 2017 and 2018 Human Exploration Research Analog (HERA) campaigns; and use a novel combination of text mining, relational event modeling, and coevolution statistical modeling.

For more information on this exciting new project, click here.

This is the second collaborative NASA grant among Prof. Contractor, Prof. DeChurch, and Prof. Bell; the first being CREWS: Crew Recommender for Effective Work in Space. This is also the fourth NASA grant the SONIC Lab has received in the past two years. Be sure to check out our work on the other two grants: SCALE and INERTIA!

Cutting costs: Sustainability matters even in complex networks

A team of researchers at Northeastern University, led by famous networks researcher and physicist Albert-Laszlo Barabasi, explored how the concept of sustainability can be implemented in network analysis. The researchers approached this idea by defining the concept of control energy or “the amount of effort needed to control real-world complex systems.” They reported that this new metric can be utilized in all kinds of real-world complex systems, such as identifying critical points in online network security systems. By using this new metric, a cost benefit analysis could be administered in order to identify exactly how much external energy needs to be inputted into drivers’ nodes in order to create the most efficient complex system.

Frames and Fields on Twitter

Abstract

We characterize an online activist field as a social arena in which participants vie for the definition of the most urgent cause or risk issue. We ask the question: to what extent is it conceptually and empirical valid to regard protest activity on Twitter, such as the Occupy Wall Street movement, as an online activist field? Network analysis is used to examine two core aspects of field theory: the behavior of incumbents vs new entrants in response to a new issue or frame, and the dynamics of field formation. This project extends earlier research concerning organizations involved in environmental social movements and online collective identity formation and contributes to emerging research on activism in the era of the “networked individual”.

The New Foundations: Emergence, Constructionism and the New Reductionism

Abstract

The science of studying emergence is not well understood among organizational scholars.  Scholars often transfer assumptions from variance analysis to this particular application of process analysis.  Further, its components parts—emerging, emergent outcomes and their properties—are often confounded leading to muddled thinking.  In this paper, I distinguish among these components.  Specifically, I discuss the features of complex systems drawing out distinctions between complex vs complicated non-linear systems, constituting vs causing, aggregation, levels, and holism.  I draw out the implications of this research approach, emphasizing the paradigm shift required to apply it from other approaches, using examples from organization studies, particularly the Strategy Microfoundations debate.
