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.

Biography 

Corinne Coen is an Associate Professor of Organizational Behavior at Weatherhead School of Management in Case Western Reserve University where she holds the Lewis Progressive Fellowship and is the Chair of the Faculty Council. She has an MBA from University of Chicago and a Ph.D. in Business Administration from the University of Michigan. Her research interests focus on the dynamics of work teams as they generate cooperation and competition, cohesion, and sub-groups.  In the pursuit of understanding these dynamic processes, Corinne has special expertise in agent-based modeling and the study of cross-level emergence.  Her work has been published in Organizational Science, Organizational Behavior and Human Decision Processes, Computational and Mathematical Organization Theory and Simulation Modeling Practice and Theory.

En el marco del Programa La UBA para el Siglo XXI, comienza el ciclo de actividades con motivo del 30º aniversario de la creación del Programa de Educación a Distancia UBAXXI, con la conferencia “Potenciando la Ciencia de Redes para abordar los grandes retos sociales”, a cargo del Prof. Noshir Contractor.

El acceso a grandes volúmenes de información sobre los fenómenos sociales en general y sobre la red en particular tiene un valor extraordinario para los científicos sociales. Pero esta apasionante oportunidad debe estar acompañada de la reflexión sobre cómo los big data pueden dar lugar a nuevas teorías y métodos. Utilizando ejemplos de su investigación en el área de redes, Contractor analizará el aporte de la Ciencia de Redes al desarrollo de nuevas comprensiones a partir de grandes volúmenes de datos. Más importante aún, ilustrará cómo estas ideas ofrecen a los científicos sociales y los estudiosos de redes sociales, una oportunidad sin precedentes para participar más activamente en la supervisión, la anticipación y el diseño de intervenciones para hacer frente a los grandes desafíos sociales. – See more at: http://citep.rec.uba.ar/blog/2016/04/20/2398/#sthash.b8XUhK7X.dpuf

Indian Monsoon: Novel approach allows early forecasting

Scientists from Potsdam Institute for Climate Impact Research used network analysis to predict Indian monsoon timing more accurately and significantly earlier. The new predictions will help farmers in the region decide when to plant their crops. As co-author Jürgen Kurths explains, “On Facebook or Twitter, you can follow how news is spreading, one posting leading to many others. In the climate system, not people but geographical regions are communicating — admittedly in a quite complex way.” The key part of the analysis was identifying regions that illustrate important warning signals and analyzing their interaction with other regions.

SONIC Researchers Publish “Citation Distance: Measuring Changes in Scientific Search Strategies” in the Proceedings of the 25th International Conference on World Wide Web

SONIC JD/PhD candidate Ryan Whalen, along with coauthors Yun Huang (senior research associate at SONIC), Craig Tanis, Anup Sawant (senior software developer at SONIC), Brian Uzzi (SONIC affiliated faculty) and Noshir Contractor (SONIC lab director) recently published an article titled “Citation Distance: Measuring Changes in Scientific Search Strategies” in the Proceedings of the 25th International Conference Companion on World Wide Web.

Abstract:

Using latent semantic analysis on the full text of scientific articles, we measure the distance between 36 million citing/cited article pairs and chart changes in citation proximity over time. The analysis shows that the mean distance between citing and cited articles has steadily increased since 1990. This demonstrates that current scholars are more likely to cite distantly related research than their peers of 20 years ago who tended to cite more proximate work. These changes coincide with the introduction of new information technologies like the Internet, and the increasing popularity of interdisciplinary and multidisciplinary research. The “citation distance” measure shows promise in improving our understanding of the evolution of knowledge. It also offers a method to add nuance to scholarly impact measures by assessing the extent to which an article influences proximate or distant future work.

Mathematicians Mapped Out Every “Game of Thrones” Relationship to Find the Main Character

It’s the network study you’ve all been waiting for! Who is the most popular Game of Thrones character? Prof. Beveridge of Macalester College and one of his undergraduate students have calculated a number of network statistics based on the proximity of names mentioned in George R. R. Martin’s famous novels. The only question is: can these metrics help predict who is likely to meet an unfortunate end in the future? If popularity is a significant predictor then I’m not looking forward to what happens next!

Noshir Speaks at the University of California Santa Barbara’s Department of Computer Science

Lab Director Noshir Contractor presented his talk “Some Assembly Required: Organizing in the 21st Century” during a Research Group Talk at the University of California Santa Barbara’s Department of Computer Science. Click here for a link to the event page.

Abstract

Recent technological advances provide comprehensive digital traces of social actions, interactions, and transactions. These data provide an unprecedented exploratorium to model the socio-technical motivations for creating, maintaining, dissolving, and reconstituting into teams. Using examples from research on scientific collaboration, software development and massively multiplayer online games, Contractor will argue that Network Science serves as the foundation for the development of social network theories and methods to help advance our ability to understand the emergence of effective teams. More importantly, he will argue that these insights will also enable effective teams by building a new generation of recommender systems that leverage our research insights on the socio-technical motivations for creating ties.
