Self-Censorship for Democrats

On the face of it, self-censorship is profoundly subversive of democracy, particularly in its talk-centric forms, and undermines the culture of openness and publicity on which it relies. This paper has two purposes. The first is to develop a conception of self-censorship that allows us to capture what is distinctive about the concept from a political perspective and which allows us to understand the democratic anxiety about self-censorship: if it is not obvious that biting our tongues is always wrong, we need a fuller account of the moral sensibility that finds it so troubling and this is elaborated here. The second is to develop an argument to the effect that this sensibility should not have the last, or only, word, but instead that self-censorship should be viewed as an ‘ordinary vice’ of democratic societies. The grounds for tolerating it rest on the democratic values that critics believe it threatens

Depth-related structure and ecological significance of cold-seep communities—a case study from the Sea of Okhotsk

We discovered and investigated several cold-seep sites in four depth zones of the Sea of Okhotsk off Northeast Sakhalin: outer shelf (160–250 m), upper slope (250–450 m), intermediate slope (450–800 m), and Derugin Basin (1450–1600 m). Active seepage of free methane or methane-rich fluids was detected in each zone. However, seabed photography and sampling revealed that the number of chemoautotrophic species decreases dramatically with decreasing water depth. At greatest depths in the Derugin Basin, the seeps were inhabited by bacterial mats and bivalves of the families Vesicomyidae (Calyptogena aff. pacifica, C. rectimargo, Archivesica sp.), Solemyidae (Acharax sp.) and Thyasiridae (Conchocele bisecta). In addition, pogonophoran tubeworms of the family Sclerolinidae were found in barite edifices. At the shallowest sites, on the shelf at 160 m, the seeps lack chemoautotrophic macrofauna; their locations were indicated only by the patchy occurrence of bacterial mats. Typical seep-endemic metazoans with chemosynthetic symbionts were confined to seep sites at depths below 370 m. A comparative analysis of the structure of seep and background communities suggests that differences in predation pressure may be an important determinant of this pattern. The abundance of predators such as carnivorous brachyurans and asteroids, which can invade seeps from adjacent habitats and efficiently prey on sessile seep bivalves, decreased very pronouncedly with depth. We conclude from the obvious correlation with the conspicuous pattern in the distribution of seep assemblages that, on the shelf and at the upper slope, predator pressure may be high enough to effectively impede any successful settlement of viable populations of seep-endemic metazoans. However, there was also evidence that other depth-related factors, such as bottom-water current, sedimentary regimes, oxygen concentrations and the supply of suitable settling substrates, may additionally regulate the distribution of seep fauna in the area. As a consequence of the pronounced pattern in the distribution of seep communities, their ecological significance as food sources of surrounding background fauna increased with water depth. Isotopic analyses suggest that in the Derugin Basin seep colonists feed on chemoautotrophic seep organisms, either directly or by preying on metazoans with chemosynthetic symbionts. In contrast, seep organisms apparently do not contribute to the nutrition of the adjacent background fauna on the shelf and at the slope. In this area, elevated epifaunal abundances at seep sites were caused primarily by the availability of suitable settling substrates rather than by an enrichment of food supply

Enron, a Perceived Crisis in Public Confidence, and the Bipartisan Campaign Reform Act of 2002

In the spring of 2002 Congress passed and President Bush signed the Bipartisan Campaign Reform Act (BCRA), the first major piece of campaign reform legislation since the early 1970s. While momentum for reform had been growing since the mid-1990s, without the Enron scandal and its potential threat to public officials, additional support to overcome the procedural barriers and opposition from the Republican leadership in both the House and Senate would have been difficult to overcome. In addition, Bush Administration ties to Enron had the effect of demobilizing the president on the issue, making it virtually impossible for him to veto a bill he fundamentally opposed. The Enron scandal provided the "window of opportunity" needed by reform-oriented elites to pass a controversial and far-ranging law that was not a high priority on the public's agenda. The end result is a law, pending a Supreme Court ruling on its constitutionality, that has the potential to alter fundamentally how electoral campaigns are funded and conducted.

Lyman series emission after valence and core excitation of water vapor

We report Lyman-series emission cross sections of neutral hydrogen dissociation fragments after valence (15–34 eV) and inner-shell (533–542 eV) excitation of water vapor with monochromatic synchrotron radiation as functions of the exciting-photon energy. In the valence excitation energy region, the thermodynamical limits of the production of the differently excited hydrogen fragments are directly observed and absolute emission cross sections are determined. For resonant inner-shell excitations, the fluorescing excited hydrogen state is found to be strongly dependent on the molecular or Rydberg-like character of the excitation
