Using an organizational informatics approach, this study explores the implications of human rights organizations’ use of censorship circumvention technologies. Through qualitative analyses of data collected through in-depth interviews, the research examines the factors influencing the use of circumvention technologies and the organizational effects of their use. The outcomes include a revised m...

A proof of strong cosmic censorship is presented for a class of solutions of the Einstein-Maxwell equations, those with polarized Gowdy symmetry. A key element of the argument is the observation that by means of a suitable choice of variables the central equations in this problem can be written in a form where they are identical to the central equations for general (i.e. non-polarized) vacuum G...

Microblogging services such as Twitter are an increasingly important way to communicate, both for individuals and for groups through the use of hashtags that denote topics of conversation. However, groups can be easily blocked from communicating through blocking of posts with the given hashtags. We propose #h00t, a system for censorship resistant microblogging. #h00t presents an interface that ...

Quantum entanglement and relativistic causality are key concepts in theoretical works seeking to unify quantum mechanics gravity. In this article, we show that the interplay between relativity theory has intriguing consequences for spacetime surrounding elementary particles with spin. Classical gravity theories predict a spin-generated magnetic dipole field causes (slight) bending around partic...

I consider competitions in which, conditional on winning or losing, the effort exerted by a competitor does not necessarily decrease his payoff. This happens, for example, in competitions for promotions in which workers are intrinsically motivated, and in research and development races in which better performance implies a higher payoff from winning. I characterize players’ equilibrium payoffs ...

In this note, we completely describe the shape of the bisector of two given points in a two-dimensional normed vector space. More precisely, we show that, depending on the position of two given points with respect to the shape of the unit circle, the following holds: the bisector of a non-strict pair of points consists of two cones and a curve, which has properties similar to those of bisectors...

A distinctive feature of modern functional logic languages like Toy or Curry is the possibility of programming non-strict and non-deterministic functions with call-time choice semantics. For almost ten years the CRWL framework [6,7] has been the only formal setting covering all these semantic aspects. But recently [1] an alternative proposal has appeared, focusing more on operational aspects. I...
