A system for ranking organizations using social scale analysis
An end-to-end system that is able to help researchers to visualize the data in an interactive fashion on a timeline is presented and it is shown that the Rasch model not only outperforms the baseline methods, but it is also the only system that performs at expert-level accuracy.
Analysing Terrorism and Counter-terrorism: A Communication Model
This article analyses terrorism and counter-terrorism within a framework of communication. This analytic framework views violence as a form of communication that interacts with other forms of social
Perspective Analysis for Online Debates
This paper develops automated perspective discovery techniques which would contribute to the understanding of features shared by each side of the debate, and shows that, compared to a semi-automated process, these algorithms not only identify larger number of relevant features, but they also yield a higher accuracy scaling of moderate to extreme organizations on both sides of a debate.
The rhetoric and reality: radicalization and political discourse
This article will illustrate how the term ‘radicalization’ has both contributed to and been the subject of the social construction of risk surrounding violence and radicalization. To this extent,
Social movements
This course investigates the history of movements for social change in American history. Students will explore efforts to alter the structure of society, from abolition through the present day. How
On General Laws and the Meaning of Measurement in Psychology
Abstract : Lately the statistical methods of psychometrics have been severely criticized in psychological quarters. Thus Skinner [1] maintains that if order is to be found in human and animal
Large-scale sparse logistic regression
An adaptive line search scheme which allows to tune the step size adaptively and meanwhile guarantees the optimal convergence rate is proposed, which demonstrates the efficiency of the proposed Lassplore algorithm for large-scale problems.
Model selection and estimation in the Gaussian graphical model
The implementation of the penalized likelihood methods for estimating the concentration matrix in the Gaussian graphical model is nontrivial, but it is shown that the computation can be done effectively by taking advantage of the efficient maxdet algorithm developed in convex optimization.
A goodness of fit test for the rasch model
The Rasch model is an item analysis model with logistic item characteristic curves of equal slope,i.e. with constant item discriminating powers. The proposed goodness of fit test is based on a
Social Science Concepts: A User's Guide
This book presents a meta-analysing of the constructed world in the context of two-Level Theories, a model based on the model developed by J. Joseph Hewitt in 1993.
