As both a trust establishment and a public institution, the Smithsonian Institution is a recipient of both public and private sector funding. This article examines the financial crisis within the Institution that resulted from increasing costs, a weakening economy, and eroding federal support. It further shows how the Institution's senior management recognized the permanence of their economic situation, accepted the structural nature of their fiscal plight, and initiated the downsizing and restructuring of a public institution that, until recently, experienced nothing but growth. 相似文献

Clinicians who treat patients using Community Treatment Orders (CTOs) face many potential dilemmas in their relations with involuntary outpatients and the exercise of their powers. We compare the dilemmas identified in the literature with those reported by responsible clinicians in New Zealand (NZ). These clinicians experienced a number of well-known dilemmas, such as determining the right moment for a person's discharge from a CTO, but they seemed less troubled by some other difficulties than might be expected, usually because they considered involuntary outpatient treatment the best option for the patient or the best way to manage the risks involved. Further dilemmas were identified by the NZ clinicians that have not been widely discussed, concerning the proper scope of clinical authority over patients under CTOs and the decision to revoke involuntary outpatient status. In conclusion, some suggestions are made as to how clinicians might best manage the dilemmas involved. 相似文献

Eliminating racial and ethnic disparities in health status and health care, a major focus of Healthy People 2010, remains on the national agenda and among the priorities for the administration of President George W. Bush. Even though the elimination of racial and ethnic health disparities challenges the whole nation, individual states are on the front line of many initiatives and are often the focus of important policy efforts. In addition, it is important to focus on states because they are already responsible for much of the health and public health infrastructure, and several states have developed initiatives dating back to the release of Margaret Heckler's report on the gaps in health outcomes by race in 1985. This article makes the case for an outcome-oriented approach and provides a summary of lessons learned based upon preliminary investigations into constructing and applying two indices, the disparity reduction profile to measure effort and the disparity index to measure outcomes. 相似文献

Five years earlier, 1- and 2-year-old children who had been injured seriously enough to require hospital ER treatment had
been recruited from the ER. For this study, as many of these children as could be found participated. The majority of former
1-year olds recalled nothing about these highly stressful events, whereas most former 2-year olds recalled a great deal. For
those former 1-year olds who did recall the target events, quality of recall was problematic. In particular, they made considerable
source confusions or intrusions into their accounts of details from other related events, producing an account that amalgamated
various events into one recollection. Forensic implications are discussed. 相似文献

A total of 2443 male individuals, previously typed for the 13 CODIS STR loci, distributed across the five North American population groups African American, Asian, Caucasian, Hispanic, and Native American were typed for the Y-STR loci DYS19, DYS385a/b, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 using the PowerPlex Y System. All population samples were highly polymorphic for the 12 Y-STR loci with the marker DYS385a/b being the most polymorphic across all sample populations. The Native American population groups demonstrated the lowest genetic diversity, most notably at the DYS393 and DYS437 loci. Almost all of the 12-locus haplotypes observed in the sample populations were represented only once in the database. Haplotype diversities were greater than 99.6% for the African Americans, Caucasians, Hispanics, and Asians. The Native Americans had the lowest haplotype diversities (Apaches, 97.0%; Navajo, 98.1%). Population substructure effects were greater for Y-haplotypes, compared with that for the autosomal loci. For the apportionment of variance for the 12 Y-STRs, the within sample population variation was the largest component (>98% for each major population group and approximately 97% in Native Americans), and the variance component contributed by the major population groups was less than the individual component, but much greater than among sample populations within a major group (11.79% versus 1.02% for African Americans/Caucasians/Hispanics and 15.35% versus 1.25% for all five major populations). When each major population is analyzed individually, the R(ST) values were low but showed significant among group heterogeneity. In 692 confirmed father-son pairs, 14 mutation events were observed with the average rate of 1.57x10(-3)/locus/generation (a 95% confidence bound of 0.83x10(-3) to 2.69x10(-3)). Since the Y-STR loci reside on the non-recombining region of the Y chromosome, the counting method is one approach suggested for conveying an estimate of the rarity of the Y-haplotype. Because the Y-STR loci are not all in disequilibrium to the same extent, the counting method is a very conservative approach. The data also support that autosomal STR frequencies can be multiplied by the upper bound frequency estimate of a Y-haplotype in the individual population group or those pooled into major population groups (i.e., Caucasian, African American, Hispanic, and Asian). These analyses support use of the haplotype population data for estimating Y-STR profile frequencies for populations residing in North America. 相似文献
