TL;DR: This paper developed a nonlinear simultaneous equation model to weigh explanations of three general sorts: the political information to which people are exposed, their ability to assimilate and organize such information, and theirmotivation to do so.
Abstract: Debates over the political sophistication of mass publics smolder on. The more fundamental question, however, is why people become as politically sophisticated or unsophisticated as they do. This paper develops a nonlinear simultaneous equation model to weigh explanations of three general sorts: the politicalinformation to which people are exposed, theirability to assimilate and organize such information, and theirmotivation to do so. The estimates suggest that interest and intelligence, representing motivation and ability, have major effects, but that education and media exposure, the big informational variables, do not. I consider the reasons and sketch some implications for the sophistication of mass publics, for the study of sophistication and other “variables of extent,” and for democratic theory.

TL;DR: In this article, the authors examine how cultural differences influence the returns of momentum strategies and find that individualism is positively associated with trading volume and volatility, as well as with the magnitude of momentum profits, and that momentum profits are also positively related to analyst forecast dispersion, transaction costs, and the familiarity of the market to foreigners.
Abstract: This paper examines how cultural differences influence the returns of momentum strategies. Cross-country cultural differences are measured with an individualism index developed by Hofstede (2001), which is related to overconfidence and self-attribution bias. We find that individualism is positively associated with trading volume and volatility, as well as to the magnitude of momentum profits. Momentum profits are also positively related to analyst forecast dispersion, transaction costs, and the familiarity of the market to foreigners, and negatively related to firm size and volatility. However, the addition of these and other variables does not dampen the relation between individualism and momentum profits.

TL;DR: In this paper, the authors proposed a multi-authority attribute-based encryption (ABE) system, where any party can become an authority and there is no requirement for any global coordination other than the creation of an initial set of common reference parameters.
Abstract: We propose a Multi-Authority Attribute-Based Encryption (ABE) system. In our system, any party can become an authority and there is no requirement for any global coordination other than the creation of an initial set of common reference parameters. A party can simply act as an ABE authority by creating a public key and issuing private keys to different users that reflect their attributes. A user can encrypt data in terms of any boolean formula over attributes issued from any chosen set of authorities. Finally, our system does not require any central authority. In constructing our system, our largest technical hurdle is to make it collusion resistant. Prior Attribute-Based Encryption systems achieved collusion resistance when the ABE system authority “tied” together different components (representing different attributes) of a user’s private key by randomizing the key. However, in our system each component will come from a potentially different authority, where we assume no coordination between such authorities. We create new techniques to tie key components together and prevent collusion attacks between users with different global identifiers. We prove our system secure using the recent dual system encryption methodology where the security proof works by first converting the challenge ciphertext and private keys to a semi-functional form and then arguing security. We follow a recent variant of the dual system proof technique due to Lewko and Waters and build our system using bilinear groups of composite order. We prove security under similar static assumptions to the LW paper in the random oracle model.
