Catch Shares in Action: British Columbia Integrated Groundfish Program

The British Columbia Integrated Groundfish Program (Integrated Program) is one of the most comprehensive catch share programs in the world. The multi-species program includes over 70 species, 30 of which are managed via quota, and includes all commercial fishermen targeting groundfish, regardless of gear type. The program includes a number of innovative design features such as quota set-asides, which are meant to encourage community development and incentivize positive treatment of crew. Additionally, the program requires 100% individual accountability of all catch and uses an innovative monitoring and catch accounting system to support accountability

Opera Highlights

The OPERA experiment is a long baseline neutrino oscillation experiment aimed at observing the $\nu_{\mu} \rightarrow \nu_{\tau}$ neutrino oscillation in the CERN neutrino to Gran Sasso beamline in the appearance mode by detecting the $\tau$ - decay. Here I will summarize the results from the run years 2008-10 with an update on observed rare decay topologies and the results of the neutrino velocity measurements.Comment: Proceedings of the 2012 Volcano Workshop: Frontier Objects in Astrophysics and Particle Physic

Neutrinos: The Big Question and Physics Opportunities

This article summarises a talk given at the 2014 Palermo workshop on Astrophysics. It covers a short review on the neutrino physics status and the potential physics opportunities of future experiments. During the last year our knowledge on the neutrino oscillation parameter $\sin^2\theta_{13}$ improved dramatically, and the large value opened the way to oscillation experiments sensitive to possible CP-violation. The first high-energetic neutrinos in the TeV range were detected in the IceCube experiment, while the Planck collaboration set further limits on the number of active neutrinos from cosmological constraints. Over the next years the Katrin will investigate the beta decay of Tritium to study the absolute neutrino mass scale, while new experiments will investigate the potential sterile neutrino scenario which could explain the event excess of the MiniBooNE and LSND experiment.Comment: Proceedings from the Frontier Research in Astrophysics, Palermo 2014, to be published in Proceedings of Scienc

Catch Shares in Action: Danish Pelagic and Demersal Individual Transferable Quota Programs

The Danish Pelagic and Demersal Individual Transferable Quota Programs (ITQ Programs) include a number of thoughtful design decisions in order to meet the programs' goals, including promoting economic growth in the fisheries sector by balancing the capacity of the fishing fleet with the available resource, and addressing social concerns. Important features of the catch share program include quota set-asides for small vessels and new entrants; Fishpools, which promote cooperation and coordination among participants; and programs to reduce discards. Denmark's catch share programs demonstrate how innovative design features can be used to promote social goals within a system introduced for economic and biological reasons

Stability of Quadratic Projection Methods

In this paper we discuss the stability of an alternative pollution-free procedure for computing spectra. The main difference with the Galerkin method lies in the fact that it gives rise to a weak approximate problem which is quadratic in the spectral parameter, instead of linear. Previous accounts on this new procedure can be found in Levitin and Shargorodsky (2002) [math.SP/0212087] and Boulton (2006) [math.SP/0503126].Comment: 19 pages, 4 figures. In this updated version we have made a small number of minor correction

Mapping of RNA- temperature-sensitive mutants of Sindbis virus: assignment of complementation groups A, B, and G to nonstructural proteins

Four complementation groups of temperature-sensitive (ts) mutants of Sindbis virus that fail to make RNA at the nonpermissive temperature are known, and we have previously shown that group F mutants have defects in nsP4. Here we map representatives of groups A, B, and G. Restriction fragments from a full-length clone of Sindbis virus, Toto1101, were replaced with the corresponding fragments from the various mutants. These hybrid plasmids were transcribed in vitro by SP6 RNA polymerase to produce infectious RNA transcripts, and the virus recovered was tested for temperature sensitivity. After each lesion was mapped to a specific region, cDNA clones of both mutants and revertants were sequenced in order to determine the precise nucleotide change responsible for each mutation. Synthesis of viral RNA and complementation by rescued mutants were also examined in order to study the phenotype of each mutation in a uniform genetic background. The single mutant of group B, ts11, had a defect in nsP1 (Ala-348 to Thr). All of the group A and group G mutants examined had lesions in nsP2 (Ala-517 to Thr in ts17, Cys-304 to Tyr in ts21, and Gly-736 to Ser in ts24 for three group A mutants, and Phe-509 to Leu in ts18 and Asp-522 to Asn in ts7 for two group G mutants). In addition, ts7 had a change in nsP3 (Phe-312 to Ser) which also rendered the virus temperature sensitive and RNA-. Thus, changes in any of the four nonstructural proteins can lead to failure to synthesize RNA at a nonpermissive temperature, indicating that all four are involved in RNA synthesis. From the results presented here and from previous results, several of the activities of the nonstructural proteins can be deduced. It appears that nsP1 may be involved in the initiation of minus-strand RNA synthesis. nsP2 appears to be involved in the initiation of 26S RNA synthesis, and in addition it appears to be a protease that cleaves the nonstructural polyprotein precursors. It may also be involved in shutoff of minus-strand RNA synthesis. nsP4 appears to function as the viral polymerase or elongation factor. The functions of nsP3 are as yet unresolved

The Large-Scale Velocity Field

I summarize both observational and theoretical developments in the last few years in measuring and understanding the large-scale velocity field of galaxies, with special attention to the bulk flow, or average peculiar velocity, within spheres centered on the Local Group.Comment: 12 pages standard Latex (w/figures).
