Trends of female access to and presence in responsible governmental positions have gained substantial attention. The research reported here assesses and seeks convergence on several issues associated with gender representation. It extends the research by focusing on top executive posts in American state governments. In particular, the presence of women agency heads in all 50 states is examined from 1970 through 2000 using the lenses of passive representativeness and active representation. The authors find, first, that women face fewer blockages in securing top posts—the glass ceilings are cracking. Second, women's access to peak executive positions springs from more solid educational, career, and organizational foundations or "floors." Third, lateral career movements are penetrating the "walls" surrounding traditionally male-dominated agency types. The essay concludes with a framework for understanding relationships involving passive representativeness, active representation, and representative results. That framework assists in shifting attention toward the consequences of both passive and active representation. 相似文献

Analytical instrumentation for Raman spectroscopy has advanced rapidly in recent years to the point where commercial field-portable instruments are available. Raman analysis with portable instrumentation is a new capability that can provide emergency response teams with on-site evaluation of hazardous materials. Before Raman analysis is accepted and implemented in the field, realistic studies applied to unknown samples need to be performed to define the reliability of this technique. Studies described herein provide a rigorous blind field test that utilizes two instruments and two operators to analyze a matrix that consists of 58 unknown samples. Samples were searched against a custom hazardous materials reference library (Hazardous Material Response Unit (HMRU) Spectral Library Database). Experimental design included a number of intentionally difficult situations including binary solvent mixtures and a variety of compounds that yield medium-quality spectra that were not contained in the HMRU library. Results showed that over 97% of the samples were correctly identified with no occurrences of false positive identifications (compounds that were not in the library were never identified as library constituents). Statistical analysis indicated equivalent performance for both the operators and instruments. These results indicate a high level of performance that should extrapolate to actual field situations. Implementation of Raman techniques to emergency field situations should proceed with a corresponding level of confidence. 相似文献

In a longitudinal developmental study, 90 girls and boys participated in a psychological investigation, and were medically examined when they were 11, 13, 15, and 18 years old. Their satisfaction with the various parts of their body was assessed by means of a questionnaire. Satisfaction was highest at age 18, with males on average more satisfied than females at all age levels. There was a fairly constant pattern of critical body features for each of the sexes. However, individual satisfaction varied greatly as a function of age and developmental level, with late maturers tending to be more satisfied than early matures at ages 11 and 18. The correlations between body image satisfaction and other variables varied as a function of the age and sex of the subjects, and are discussed in relation to the growth process.This research was supported by the Signe and Ane Gyllenberg Foundation.Received Ph.D. from the University of Turku, Finland. Research interest is the life process of adolescents. 相似文献

When used in the health care industry, an MFN clause is a contractual agreement that guarantees a health insurer the same best price as their market competitors. MFN clauses have the effect of unnecessarily raising consumer costs, reducing choice among providers, constraining access to care and preventing the development of alternative health care delivery models. The purpose of this paper is four-fold. First, to design a four-quadrant matrix to evaluate the pro-competitive and anticompetitive purposes and effects of MFN clauses under Section 1 of the Sherman Act. Second, to defeat the jurisprudential presumption that MFN clauses are pro-competitive in the health care industry and to recommend that this presumption be abolished. Third, to examine the U.S. Department of Justice's paradigmatic shift over the last decade toward prosecuting large insurers who employ MFN clauses resulting in U.S. Consent Decrees. Fourth, to outline the indicia of a meritorious claim against an insurer who employs an MFN clause. 相似文献
