Flow-based Influence Graph Visual Summarization

Visually mining a large influence graph is appealing yet challenging. People are amazed by pictures of newscasting graph on Twitter, engaged by hidden citation networks in academics, nevertheless often troubled by the unpleasant readability of the underlying visualization. Existing summarization methods enhance the graph visualization with blocked views, but have adverse effect on the latent influence structure. How can we visually summarize a large graph to maximize influence flows? In particular, how can we illustrate the impact of an individual node through the summarization? Can we maintain the appealing graph metaphor while preserving both the overall influence pattern and fine readability? To answer these questions, we first formally define the influence graph summarization problem. Second, we propose an end-to-end framework to solve the new problem. Our method can not only highlight the flow-based influence patterns in the visual summarization, but also inherently support rich graph attributes. Last, we present a theoretic analysis and report our experiment results. Both evidences demonstrate that our framework can effectively approximate the proposed influence graph summarization objective while outperforming previous methods in a typical scenario of visually mining academic citation networks.Comment: to appear in IEEE International Conference on Data Mining (ICDM), Shen Zhen, China, December 201

Computable Rationality, NUTS, and the Nuclear Leviathan

This paper explores how the Leviathan that projects power through nuclear arms exercises a unique nuclearized sovereignty. In the case of nuclear superpowers, this sovereignty extends to wielding the power to destroy human civilization as we know it across the globe. Nuclearized sovereignty depends on a hybrid form of power encompassing human decision-makers in a hierarchical chain of command, and all of the technical and computerized functions necessary to maintain command and control at every moment of the sovereign's existence: this sovereign power cannot sleep. This article analyzes how the form of rationality that informs this hybrid exercise of power historically developed to be computable. By definition, computable rationality must be able to function without any intelligible grasp of the context or the comprehensive significance of decision-making outcomes. Thus, maintaining nuclearized sovereignty necessarily must be able to execute momentous life and death decisions without the type of sentience we usually associate with ethical individual and collective decisions

Law and economics, consequentialism and legal pragmatism: the influence of Oliver Holmes Jr.

This paper aims to present the similarities and differences between Posner's defense of Law and Economics (LAE) and Holmes' pragmatism. The investigation is centered in the arguments of economic consequences of judicial decisions. Law and Economics tend to emphasize these arguments as a determinant characterization of legal pragmatism. These arguments involve some dilemmas: Is it possible to eliminate a rule, or reinterpret it according to the effect of its application in practical life? May these economic consequences serve as argument for a replacement of traditional interpretation? To what extent can we rule out the law with arguments of consequence? Despite the influence, LAE has some important differences with respect Holmes' legal pragmatism. Posner's LAE involves the economic principle of wealth maximization and its relations with utilitarianism and economic liberalism. Consequentialism in Holmes, by contrast, is based on a teleological interpretation of existing rules. It is important that the judge does not decide based on a specific economic theory. Also, legal pragmatism does not advocate abandoning the tenets of positivism that form the basis for the rule of law. Holmes defends a judicial restraint. Accordingly, the argument of consequence must have previous limits in precedents and statutes. However, both legal pragmatism and LAE are connected by the idea that the adaptation of the law to a reasonable end can not be absent from the canons of interpretation and adjudication

THE UTILITARIAN FOUNDATIONS OF THE ECONOMIC APPROACH TO HUMAN BEHAVIOR.

The economic approach to the study of human behavior has been presented by its foremost representative as the most effective method of studying social phenomena. Gary Becker´s view supposes that, on the one hand, all social phenomena can be explained as a consequence of individual actions and, on the other, there is a stable pattern of individual behavior economics has been able to understand thoroughly. Hence, economics, according to this view, is no longer limited to the study of a certain domain of human actions or to the understanding of material wealth or the necessary conditions for the material reproduction of society. Economics is a method that gives the social scientist the necessary tools to understand and even transform the world that surrounds him/her. Becker clearly acknowledges the direct link between his approach and Jeremy Bentham´s theory. Beyond the apparent connections regarding their conception of human nature there is one central point that links the two authors: their view of economics as an attitude of the human mind, an inherent capacity to calculate that explains all human actions. This paper argues that Bentham provides the philosophical groundings for Becker´s theory. The application of the principle of utility to every aspect of human behavior justifies economic imperialism by transforming economics into a method of general analysis of human behavior. Indeed, economics is no longer defined according to its subject matter but according to its method, which means an increasing scope explaining Becker´s claim that the economic approach provides a rigorous framework for the analysis of all social phenomena.Gary Becker
