By National Research Council, Division of Behavioral and Social Sciences and Education, Committee on National Statistics, Committee to Review the 2000 Decade Design of the Scientists and Engineers Statistical Data System (SESTAT)

The prior decade has verified the software of SESTAT, however the SESTAT layout indicates a few deficiencies with admire to reaction charges, assurance of populations of curiosity, and its skill to help a few worthwhile analyses. To take on these deficiencies, NSF has proposed 3 attainable layout innovations for making improvements to the database and requested the nationwide study Council's Committee on nationwide information (CNSTAT) to shape the Committee to check the 2000 Decade layout of the SESTAT.

This is the document of that committee. It provides our knowing of the needs and features of the SESTAT, applies the factors we think are vital for assessing layout recommendations for the database, presents our advice for the easiest method of undertake within the 2000 decade, and gives our encouragement to NSF to pursue possibilities to enhance the knowledge of the numbers and features of scientists and engineers within the United States.

Algorithmic Foundation of Multi-Scale Spatial Representation (2006)(en)(280s)

With the frequent use of GIS, multi-scale illustration has develop into a big factor within the realm of spatial information dealing with. targeting geometric adjustments, this source offers finished assurance of the low-level algorithms to be had for the multi-scale representations of alternative kinds of spatial gains, together with aspect clusters, person traces, a category of strains, person components, and a category of parts.

INFORMATION RANDOMNESS & INCOMPLETENESS Papers on Algorithmic Information Theory

"One will locate [Information, Randomness and Incompleteness] every kind of articles that are popularizations or epistemological reflections and displays which enable one to quickly receive an actual proposal of the topic and of a few of its purposes (in specific within the organic domain).

The two columns involving SESTAT indicate the frame from which the SESTAT survey was selected. 4 4Westat (2002b, 2002c) identifies a fourth option that focuses on supplementing the old panels. NSF has presented no advantages associated with the fourth option, and the committee has therefore addressed only three options. 15 16 IMPROVING THE DESIGN OF SESTAT TABLE 3-1 Current SESTAT Design and Decade 2000 SESTAT Design Options Current SESTAT Design Population Group Pre-1990 bachelor’s and master’s Original Survey NSCG 1993 Current Frame 1990 postcensal followup 1991-1992 bachelor’s and master’s NSRCG 1993 IPEDS- based 1993-1994 bachelor’s and master’s NSRCG 1995 IPEDS- based 1995-1996 bachelor’s and master’s NSRCG 1997 IPEDS- based 1997-1998 bachelor’s and master’s NSRCG 1999 IPEDS- based 1999-2000 bachelor’s and master’s NSRCG 2001 IPEDS- based 2001-2002 bachelor’s and master’s NSRCG 2003 SDR None To be determined SED None Post 1990 census non-S&E degrees working in S&E None None Degrees lower than bachelors None None Doctorates Post 1990 census foreign degrees SOURCE: Westat (2002a: Exhibit 3-1).

This survey would include persons who, in April 2000, had received at least a bachelor’s degree, were 72 years of age or younger, were not institutionalized, and were living in the United States or overseas serving in the armed forces. In 2003, this sample would be contacted and interviewed for the National Survey of College Graduates. On the basis of the interview, those persons in the 2003 sample who (1) are college graduates with S&E degrees or (2) have a college degree and are working in S&E occupations would be screened into the SESTAT sample.

To the extent that the adjustment consists of calibrating the 1990-panel results to the 2000-panel results, the effective sample size would essentially be the size of the 2000 panel. In other words, the data for the 1990 panel would be almost completely wasted. Even if the two samples produce very similar results for most outcomes, that finding would not provide complete assurance that there is no bias in the data from the 1990 panel. Consequently, it would still be EVALUATION OF THE DESIGN OPTIONS 25 improper to place much more confidence in the combined results than one would in results based on data from the 2000 panel alone.
