Improvi ng Federal Informati on Systems Management: Technological Opportunityes and Social Constraints
The management of data processing systems in the Federal government is rapidly approaching a state of crisis.1 The Federal information systems inventory is a collection of outdated hardware as well as software techniques and systems which were abandoned 1 ong ago in the private sector. Projects have such long lead times that when systems are finally devel oped they are outmoded or no 1 onger meet current requi rements. A number of sol uti ons have been proposed which range from new rul es and procedures to i ncreased use of private contractors in delivering EDP resources. Many of the proposed solutions have more to do with the political philosophy of the proposers than with the realities of data processing management or the underlying political processes which make EDP management so complex in the government sector. This paper examines the causes of Federal FDP management problems and the political questions that must be resolved for any proposed solutions to succeed
Correlations of Solar Neutrino Observables for SNO
Neutrino oscillation scenarios predict correlations, and zones of avoidance,
among measurable quantities such as spectral energy distortions, total fluxes,
time dependences, and flavor content. The comparison of observed and predicted
correlations will enhance the diagnostic power of solar neutrino experiments. A
general test of all presently-allowed (two neutrino) oscillation solutions is
that future measurements must yield values outside the predicted zones of
avoidance. To illustrate the discriminatory power of the simultaneous analysis
of multiple observables, we map currently allowed regions of neutrino masses
and mixing angles onto planes of quantities measurable with the Sudbury
Neutrino Observatory (SNO). We calculate the correlations that are predicted by
vacuum and MSW (active and sterile) neutrino oscillation solutions that are
globally consistent with all available neutrino data. We derive approximate
analytic expressions for the dependence of individual observables and specific
correlations upon neutrino oscillations parameters. We also discuss the
prospects for identifying the correct oscillation solution using multiple SNO
observables.Comment: Accepted Phys Rev D. Included new figure. Related material
