Excerpts from the Novel, Bear War-den

A woman park warden who works in Rocky Mountain National Park spends her time on such tasks as bear patrol, locating tourists who are lost or in other physical danger, and policing park rules. She has a particular affinity for grizzly bears, largely stemming from an experience she had in a Neolithic cave in Spain. During her work and her travels, she observes various ways in which bears are mistreated in parks, sometimes even by researchers with seemingly good intentions. While an out-of-control fire rages through the national park, the woman park warden, with two grizzly bear skulls in hand, begins a difficult and dream-like journey to the park boundary—where wild animals can seem like ghosts and trauma can strike as suddenly as lightning

Signalling Rivalry and Quality Uncertainty in a Duopoly

This paper considers price competition in a duopoly with quality uncertainty. The established firm (the `incumbent') offers a quality that is publicly known; the other firm (the `entrant') offers a new good whose quality is not known by some consumers. The incumbent is fully informed about the entrant's quality. This leads to price signalling rivalry because the incumbent gains and the entrant loses if observed prices make the uninformed consumers more pessimistic about the entrant's quality. When the uninformed consumers' beliefs satisfy the `intuitive criterion' and the `unprejudiced belief refinement', prices signal the entrant's quality only in a two-sided separating equilibrium and are identical to the full information outcome

Megaton Water Cerenkov Detectors and Astrophysical Neutrinos

Although formal proposals have not yet been made, the UNO and Hyper-Kamiokande projects are being developed to follow-up the tremendously successful program at Super-Kamiokande using a detector that is 20-50 times larger. The potential of such a detector to continue the study of astrophysical neutrinos is considered and contrasted with the program for cubic kilometer neutrino observatories.Comment: 4 pages Submitted to the Proceedings of the 2004 Neutrino Oscillation Workshop, Otranto Ital

Direct Electron Microscopy Study on the Morphological Diversity of Bacteriophage Populations in Lake Plußsee

Direct electron microscopy of bacteriophages adsorbed to a carbon film without prior enrichment by specific host strains or concentration by physical or chemical methods was used to study the morphological diversity of natural bacteriophage assemblages in a North German lake. All samples contained a mixture of morphologically different tailed viruses, which were regarded as bacteriophages. Most of them had isometric heads and long noncontractile tails, belonging to morphotype B1 (Siphoviridae). In addition, members of morphotypes A1 (Myoviridae), B2 (Siphoviridae with elongated heads), and C1 (Podoviridae) were present in lower numbers. Only one cubic virus was detected, while no filamentous or pleomorphic phages were found. Up to 11 different phages per sample, and a total of 39 phages when all samples were considered together, could be distinguished by morphological criteria. The total number of phages was estimated to be on the order of 108/ml

Unintended Consequences and Intended Non-Consequences

The idea that government policies have unintended consequences has become a fixture of political argument, indeed a cliché. One can hardly get through a day’s newspaper editorials without encountering it with respect to something in the news—the TARP bailouts, the North Korea bailouts, executive pay caps, local issues such as the drinking age and the driving age.
