Developing, Implementing and Evaluating Policies to Support Fisheries Co-management
The aim of this document is to bring together a number of the lessons relating to the development, implementation and evaluation of policies to support co-management that have emerged from projects undertaken through the DFID Fisheries Management Science Programme (FMSP) and elsewhere. It is beyond the scope of this document to provide a comprehensive analysis or guide. It seeks to highlight some experiences and some areas that need to be considered by policy makers when attempting to develop sustainably co-managed fisheries. This document is targeted to fisheries policy makers, and decision-makers concerned with the fisheries sector

The Search for Maximal Values of min(A,B,C) / gcd(A,B,C) for A^x + B^y = C^z
This paper answers a question asked by Ed Pegg Jr. in 2001: "What is the
maximal value of min(A,B,C)/ gcd(A,B,C) for A^x + B^y = C^z with A,B,C >= 1;
x,y,z >= 3?" Equations of this form are analyzed, showing how they map to
exponential Diophantine equations with coprime bases. A search algorithm is
provided to find the largest min/gcd value within a given equation range. The
algorithm precalculates a multi-gigabyte lookup table of power residue
information that is used to eliminate over 99% of inputs with a single array
lookup and without any further calculations. On inputs that pass this test, the
algorithm then performs further power residue tests, avoiding modular powering
by using lookups into precalculated tables, and avoiding division by using
multiplicative inverses. This algorithm is used to show the largest min/gcd
value for all equations with C^z <= 2^100.Comment: Body: 16 pages, Appendices: 11 pages, 5 tables, 1 figur
Co-management: A Synthesis of the Lessons Learned from the DFID Fisheries Management Science Programme
For the last eleven years, the UK Department for International Development (DfID) have been funding research projects to support the sustainable management of fisheries resources (both inland and marine) in developing countries through the Fisheries Management Science Programme (FMSP). A number of these projects that have been commissioned in this time have examined fisheries co-management. While these projects have, for the most part, been implemented separately, the FMSP has provided an opportunity to synthesise and draw together some of the information generated by these projects. We feel that there is value in distilling some of the important lessons and describing some of the useful tools and examples and making these available through a single, accessible resource. The wealth of information generated means that it is impossible to cover everything in detail but it is hoped that this synthesis will at least provide an overview of the co-management process together with some useful information relating to implementing co-management in a developing country context and links to the more detailed re-sources available, in particular on information systems for co-managed fisheries, participatory fish stock assessment (ParFish) and adaptive learning that have, in particular, been drawn upon for this synthesis. This synthesis is aimed at anyone interested in fisheries management in a developing country context
Geodesics in the Generalized Schwarzschild Solution
Since Schwarzshild discovered the point-mass solution to Einstein's equations
that bears his name, many equivalent forms of the metric have been catalogued.
Using an elementary coordinate transformation, we derive the most general form
for the stationary, spherically-symmetric vacuum metric, which contains one
free function. Different choices for the function correspond to common
expressions for the line element. From the general metric, we obtain particle
and photon trajectories, and use them to specify several time coordinates
adapted to physical situations. The most general form of the metric is only
slightly more complicated than the Schwarzschild form, which argues effectively
for teaching the general line element in place of the diagonal metric.Comment: 7 pages, 1 figure; revised to reflect referee comments; submitted to
