  • Price and Quantity Indices for Aquaculture Production in Europe

    Creator:
    Millán, Joaquín A. and Aldaz, Natalia
    Abstract:
    This paper considers the modelling of aggregate price and quantity of aquaculture production in the European countries since mid-80s. In general, the evolution of aquaculture production only considers the evolution of total value and total weight. The heterogeneity of aquaculture production is neglected. As a consequence, the unit value ('price')...

  • Measuring Economic Performance in a Fishery: An Index Number Profit Decomposition

    Creator:
    Fox, Kevin J., Grafton, R. Quentin, Kompas, Tom, and Nhu Che, Tuong
    Abstract:
    A method is introduced and applied to analyse changed in productivity of firms harvesting in a multi-species fishery. The index-number technique decomposes firm profits into its contributions and can be used to assess economic performance by both regulators and individual firms across an industry and over time. Using an unbalanced...

    Chen, Guoning, Deng, Qingqing, Szymczak, Andrzej, Laramee, Robert, and Zhang, Eugene
    Abstract:
    Reliable analysis of vector elds is crucial for the rigorous interpretation of the ow data stemming from a wide range of engineering applications. Morse decomposition of a vector field has proven a useful topological representation that is more numerically stable than previous vector field skeletons. In this paper, we enhance...

    Abstract:
    This research examines the effect of recent landownership changes and new management stewardship mechanisms (e.g., forest certification and working forest conservation easements) on disturbance rates in Maine forests. We quantify forest disturbance rates between 2000 and 2007 and forest cover type composition in 2007, as detected by Landsat Thematic Mapper...

    Roth, Travis R. and Nolin, Anne W.
    Abstract:
    The Forest Elevation Snow Transect (ForEST) project is a paired site elevational snow study. It is designed to measure how snow accumulates and ablates under different forest structures across an elevation range. The ForEST project has been ongoing since the winter of 2011-2012 within the McKenzie River Basin of the...
