The Space Physics Environment Data Analysis System (SPEDAS)
With the advent of the Heliophysics/Geospace System Observatory (H/GSO), a complement of multi-spacecraft missions and ground-based observatories to study the space environment, data retrieval, analysis, and visualization of space physics data can be daunting. The Space Physics Environment Data Analysis System (SPEDAS), a grass-roots software development platform (www.spedas.org), is now officially supported by NASA Heliophysics as part of its data environment infrastructure. It serves more than a dozen space missions and ground observatories and can integrate the full complement of past and upcoming space physics missions with minimal resources, following clear, simple, and well-proven guidelines. Free, modular and configurable to the needs of individual missions, it works in both command-line (ideal for experienced users) and Graphical User Interface (GUI) mode (reducing the learning curve for first-time users). Both options have âcrib-sheets,â user-command sequences in ASCII format that can facilitate record-and-repeat actions, especially for complex operations and plotting. Crib-sheets enhance scientific interactions, as users can move rapidly and accurately from exchanges of technical information on data processing to efficient discussions regarding data interpretation and science. SPEDAS can readily query and ingest all International Solar Terrestrial Physics (ISTP)-compatible products from the Space Physics Data Facility (SPDF), enabling access to a vast collection of historic and current mission data. The planned incorporation of Heliophysics Application Programmerâs Interface (HAPI) standards will facilitate data ingestion from distributed datasets that adhere to these standards. Although SPEDAS is currently Interactive Data Language (IDL)-based (and interfaces to Java-based tools such as Autoplot), efforts are under-way to expand it further to work with python (first as an interface tool and potentially even receiving an under-the-hood replacement). We review the SPEDAS development history, goals, and current implementation. We explain its âmodes of useâ with examples geared for users and outline its technical implementation and requirements with software developers in mind. We also describe SPEDAS personnel and software management, interfaces with other organizations, resources and support structure available to the community, and future development plans

Effects of Global Budgeting on the Distribution of Dentists and Use of Dental Care in Taiwan
OBJECTIVE: To examine the effects of global budgeting on the distribution of dentists and the use and cost of dental care in Taiwan. DATA SOURCES: (1) Monthly dental claim data from January 1996 to December 2001 for the entire insured population in Taiwan. (2) The 1996â2001 population information for the cities, counties and townships in Taiwan, abstracted from the Taiwan-Fukien Demographic Fact Book. STUDY DESIGN: Longitudinal, using the autocorrelation model. PRINCIPAL FINDINGS: Results indicated decline in dental care utilization, particularly after the implementation of dental global budgeting. With few exceptions, dental global budgeting did not improve the distribution of dental care and dentist supply. CONCLUSIONS: The experience of the dental global budget program in Taiwan suggested that dental global budgeting might contain dental care utilization and that several conditions might have to be met in order for the reimbursement system to have effective redistributive impact on dental care and dentist supply
