Between Facts and Norms: Contributions to a Discourse Theory of Law and Democracy

This is a review of Collected Works of John Tate. Parts I, II, edited by Barry Mazur and Jean-Pierre Serre. American Mathematical Society, Providence, Rhode Island, 2016. For several decades it has been clear to the friends and colleagues of John Tate that a “Collected Works” was merited. The award of the Abel Prize to Tate in 2010 added impetus, and finally, in Tate’s ninety-second year we have these two magnificent volumes, edited by Barry Mazur and Jean-Pierre Serre. Beyond Tate’s published articles, they include five unpublished articles and a selection of his letters, most accompanied by Tate’s comments, and a collection of photographs of Tate. For an overview of Tate’s work, the editors refer the reader to [4]. Before discussing the volumes, I describe some of Tate’s work. 1. Hecke L-series and Tate’s thesis Like many budding number theorists, Tate’s favorite theorem when young was Gauss’s law of quadratic reciprocity. When he arrived at Princeton as a graduate student in 1946, he was fortunate to find there the person, Emil Artin, who had discovered the most general reciprocity law, so solving Hilbert’s ninth problem. By 1920, the German school of algebraic number theorists (Hilbert, Weber, . . .) together with its brilliant student Takagi had succeeded in classifying the abelian extensions of a number field K: to each group I of ideal classes in K, there is attached an extension L of K (the class field of I); the group I determines the arithmetic of the extension L/K, and the Galois group of L/K is isomorphic to I. Artin’s contribution was to prove (in 1927) that there is a natural isomorphism from I to the Galois group of L/K. When the base field contains an appropriate root of 1, Artin’s isomorphism gives a reciprocity law, and all possible reciprocity laws arise this way. In the 1930s, Chevalley reworked abelian class field theory. In particular, he replaced “ideals” with his “idèles” which greatly clarified the relation between the local and global aspects of the theory. For his thesis, Artin suggested that Tate do the same for Hecke L-series. When Hecke proved that the abelian L-functions of number fields (generalizations of Dirichlet’s L-functions) have an analytic continuation throughout the plane with a functional equation of the expected type, he saw that his methods applied even to a new kind of L-function, now named after him. Once Tate had developed his harmonic analysis of local fields and of the idèle group, he was able prove analytic continuation and functional equations for all the relevant L-series without Hecke’s complicated theta-formulas.

The collected works

Conclusions and Recommendations, are particularly interesting in view of the controversies aroused by the Warnock Report. Many of the recommendations contained here are similar to Warnock's (for example, concerning the legitimacy of AID children, the need for a licensing authority to supervise the work ofAID and IVF centres, etc), but others are at odds with the corresponding Warnock recommendations. In general, the authors place higher value on the family as an institution than did the Warnock Committee and display a much livelier awareness of the possible social dangers of the new techniques. One weakness of the book is that since its authors are approaching these topics from the standpoint of social scientists, their recommendations for legislative action which surely must be based on properly ethical considerations, not merely sociological ones seem devoid of any satisfactory rational support. For example, they concede that experimentation on human embryos is an objectionable practice, since 'the material acting as the subject of the experimentation is a human being at the beginning of its individual development' (p 178); but the practical recommendation which they make concerning this practice is disappointingly feeble:

Projections of Power: Framing News, Public Opinion, and U.S. Foreign Policy

E-cigarettes are widely promoted on the Internet, but little is known about what kinds of information about them are available online. This study examines message, source, and health information characteristics of e-cigarette videos on the popular online video-sharing platform YouTube. A content analysis of 365 e-cigarette videos indicates that 85% of the videos were sponsored by marketers. These videos highlight e-cigarettes' economic and social benefits, featuring a low level of fear appeal and negative message valence and a high level of marketing information about e-cigarette products. They also convey certain health claims that have been proscribed by the U.S. Food and Drug Administration, the prevalence of which warrants ongoing monitoring and regulatory guidelines for online e-cigarette marketing.

Risk Perceptions and Risk Characteristics

Habermas’s late theory of the public sphere is fundamentally about democracy and growing complexity. The network form is at the core of growing complexity, and the centrality of networks in the economy, political system, civil society, and the lifeworld calls for revisions in central theoretical assumptions about the structure of the public sphere. We argue that in order to maintain Habermas’s larger democratic project, we will have to rethink theoretical assumptions linked to its neo-Parsonsian systems theoretical foundations and to systematically integrate new network forms of social life into theory.

The Networked Public Sphere

Focusing on several message features that are prominent in antismoking campaign literature, this content-analytic study examines 934 antismoking video clips on YouTube for the following characteristics: message sensation value (MSV) and three types of message appeal (threat, social and humor). These four characteristics are then linked to YouTube's interactive audience response mechanisms (number of viewers, viewer ratings and number of comments) to capture message reach, viewer preference and viewer engagement. The findings suggest the following: (i) antismoking messages are prevalent on YouTube, (ii) MSV levels of online antismoking videos are relatively low compared with MSV levels of televised antismoking messages, (iii) threat appeals are the videos' predominant message strategy and (iv) message characteristics are related to viewer reach and viewer preference.
