Censorship and Two Types of Self-Censorship∗†
We propose and defend a distinction between two types of self-censorship: public and private. In public self-censorship, individuals restrain their expressive attitudes in response to public censors. In private self-censorship, individuals do so in the absence of public censorship. We argue for this distinction by introducing a general model which allows us to identify, describe, and compare a ...
متن کاملCensorship in libraries
Censorship is an issue which has been present throughout recorded history. From the beginning, it has been used by individuals and groups to prevent and control the creation, access and dissemination of ideas and information. It has taken many different forms and occurred for many different reasons. The relationship between librarians and censorship is, and has been, a troubled one. The difficu...
متن کاملProof-of-Censorship: Enabling centralized censorship-resistant content providers
Content providers often face legal or economic pressures to censor or remove objectionable or infringing content they host. While decentralized providers can enable censorship-resistant storage, centralized content providers remain popular for performance and usability reasons. But centralized content providers can always choose not to respond to requests for a specific file, making it difficul...
متن کاملTopological censorship.
All three-manifolds are known to occur as Cauchy surfaces of asymptotically flat vacuum spacetimes and of spacetimes with positive-energy sources. We prove here the conjecture that general relativity does not allow an observer to probe the topology of spacetime: any topological structure collapses too quickly to allow light to traverse it. More precisely, in a globally hyperbolic, asymptoticall...
متن کاملCosmic Censorship in Quantum Gravity
We study cosmic censorship in the Reissner-Nordstrom charged black hole by means of quantum gravity holding near the apparent horizons. We consider a gedanken experiment whether or not a black hole with the electric charge Q less than the mass M (Q < M) could increase its charge to go beyond the extremal limit Q = M by absorbing the external charged matters. If the black hole charge could excee...
