The Live Birth Information System (SINASC) was implemented in 1990 for the purpose of providing information about the live-birth characteristics for the establishment of specific health indicators. This work evaluates the information quality of SINASC in relation to its data completeness and coverage for five municipalities from the State of Acre from 2005 to 2010. Lack of information (not fill...
Research was undertaken to evaluate alternative methods of selecting a sample of eligible respondents for the National Medical Expenditure Survey (NM ES) from the National Health Interview Survey (N HIS). This report presents estimates of the effects of alternative design options, obtained by statistical modeling techniques, for linking the NMES with the NH IS, The estimated survey costs for al...
T he 1999 Purdue Land Values Survey indicates that the value of an acre of average bare Indiana cropland was $2,092 per acre in June 1999. This was $63 less than the value reported in June 1998, a 2.9 percent decrease. This decline ends 11 consecutive years of increasing values. Cash rents declined from 1998 to 1999 on average land by a little less than two percent to $110 per acre. This is the...
Many colleges throughout the nation consider the experience of its undergraduates in classes, research, residence halls, dining, and community involvement. It seems that the standard method to collect data from the students is to have them complete surveys. It is the most efficient way to systematically collect information, especially with the size of some schools. It is believed that when eval...
The Standard Model does not provide a very good fit to the most recent precision electroweak data from LEP, due primarily to the observed branching ratios for Z decay to bb̄ and cc̄. The possibility that an extension of the Standard Model with low-energy supersymmetry can improve the agreement between data and theory is considered. Invited Talk at the 1995 International Europhysics Conference on ...
T he 1998 Purdue Land Values survey indicates that the value of an acre of average bare Indiana cropland was $2,155 per acre in June 1998, $55 more than the all-time peak reached in 1981. This is an increase of $158 per acre, or approximately 8 percent, over the value reported in 1997. In each of the past five years, annual increases in the value of this land have ranged from about $100 to over...
The Las Campanas Redshift Survey (LCRS) is among the first galaxy redshift surveys to sample a reasonably fair volume of the local Universe. On the largest scales (≫ 100 h Mpc), the galaxy distribution appears smooth; on relatively small scales ( < ∼ 10 h Mpc), the LCRS tends to confirm the clustering characteristics observed in previous, shallower surveys. Here, however, we concern ourselves p...
To efficiently fuse multi-spectral (MS) and panchromatic (PAN) images acquired from THEOS satellite, the authors offer proper parameters to improve IHS fusion technique based on its spectral responsivity. This concept was originally contributed by Tu et al., applied to IKONOS image fusion. Red and NIR bands of THEOS imagery with lower response were adjusted to be higher and close to the respons...
We have started a search for High Redshift Radio Galaxies (HZRGs) in an area covering 7 sr by selecting a sample of Ultra Steep Spectrum (USS) sources with a low flux density cut-off S1400 > 10 mJy and a steep spectral index cut-off of α < −1.3 (S ∝ ν) from the WENSS, NVSS and TEXAS surveys. Our first results for 27 sources show that we are almost twice as effective in finding HZRGs than than s...
