This study investigated the effects of family structure (parents together or not) and parental discord (ratings of the happiness of the marriage of biological parents) on the self-esteem of 199 female undergraduates. Family structure and happiness ratings were substantially related, with those separated rated as less happy. Self-esteem was significantly related to parental happiness, even with family structure controlled, but not to family structure with parental happiness controlled. With the sample divided into three groups (happy-together, unhappy-together, and separated) ANOVA showed a significant effect for group, with the unhappy-together group showing significantly lower self-esteem than the happy-together group, and the separated group intermediate. Parental discord thus appears to lower the selfesteem of daughters, whereas separation of parents does not. These findings support Heatherington's idea that children may be better off in a stable family where parents are divorced than in an intact family with much parental discord.Thanks are expressed to Susan Stevenson Cowles for her contributions to all stages of the study, and to Judith Fidati, Anita Katz, and Susanne Long for their assistance in the scoring and statistical analyses. The author is also grateful to Andrew Cherlin, Edmund Henderson, and Ruth C. Wylie for their helpful suggestions.Barbara H. Long is Professor Emeritus at Goucher College, where she has taught for 20 years. She is a social psychologist, having received her Ph.D. from the University of Delaware and has, at present, research interests in the attitudes of young women towards marriage and career. 相似文献

A sensitive analytical method was developed for quantitative analysis of delta(9)-tetrahydrocannabinol (delta(9)-THC), 11-nor-delta(9)-tetrahydrocannabinol-carboxylic acid (delta(9)-THC-COOH), cannabinol (CBN) and cannabidiol (CBD) in human hair. The identification of delta(9)-THC-COOH in hair would document Cannabis use more effectively than the detection of parent drug (delta(9)-THC) which might have come from environmental exposure. Ketamine was added to hair samples as internal standard for CBN and CBD. Ketoprofen was added to hair samples as internal standard for the other compounds. Samples were hydrolyzed with beta-glucuronidase/arylsulfatase for 2h at 40 degrees C. After cooling, samples were extracted with a liquid-liquid extraction procedure (with chloroform/isopropyl alcohol, after alkalinization, and n-hexane/ethyl acetate, after acidification), which was developed in our laboratory. The extracts were analysed before and after derivatization with pentafluoropropionic anhydride (PFPA) and pentafluoropropanol (PFPOH) using a Hewlett Packard gas chromatographer/mass spectrometer detector, in electron impact mode (GC/MS-EI). Derivatized delta(9)-THC-COOH was also analysed using a Hewlett Packard gas chromatographer/mass spectrometer detector, in negative ion chemical ionization mode (GC/MS-NCI) using methane as the reagent gas. Responses were linear ranging from 0.10 to 5.00 ng/mg hair for delta(9)-THC and CBN, 0.10-10.00 ng/mg hair for CBD, 0.01-5.00 ng/mg for delta(9)-THC-COOH (r(2)>0.99). The intra-assay precisions ranged from <0.01 to 12.40%. Extraction recoveries ranged from 80.9 to 104.0% for delta(9)-THC, 85.9-100.0% for delta(9)-THC-COOH, 76.7-95.8% for CBN and 71.0-94.0% for CBD. The analytical method was applied to 87 human hair samples, obtained from individuals who testified in court of having committed drug related crimes. Quantification of delta(9)-THC-COOH using GC/MS-NCI was found to be more convenient than GC/MS-EI. The latter may give rise to false negatives due to the detection limit. 相似文献

The policy of hospital autonomy has been discussed for some time in Uganda. There is little evidence from Uganda or elsewhere that increased autonomy will improve hospital performance. This article compares the performance of three private not‐for‐profit (PNFP) and public hospital pairs to address this question. PNFP and public hospitals have similar management structures but PNFP hospitals had better trained managers and a church affiliated chair in the hospital management committee. Both types have problems with personnel management but these appear more pronounced in public hospitals. Drug supply management appears better in PNFP hospitals. Overall, workloads are similar, but analysis of patterns of utilisation and prices across services suggest that patient choice of facilities is influenced by relative price levels, and that willingness to pay is higher for PNFP services. PNFP hospitals are more successful at generating revenue. There are no clear differences in efficiency between PNFP and public hospitals but there is some evidence of higher quality levels in PNFP hospitals. PNFP hospitals' performance is plausibly related to three areas of managerial autonomy. First, better management of drug supply is facilitated by their freedom to purchase drugs from the open market. Second, greater success with personnel management is plausibly related to their greater autonomy over staffing. Third, higher levels of cost recovery are enabled by their freedom to set fees. However, differences in accountability and competence of hospital management, and population willingness to pay for services may also help to explain differences. Further, the use of PNFP financing strategy by public hospitals has implications for universal access to hospital services. Although there appear to be potential advantages from greater public hospital autonomy, the Ugandan government should ensure it has developed strategies to enhance public hospital management and to protect access to public hospitals before advancing further with hospital autonomy policy.

Models of prototyped and non-prototyped competitions for prime contracts from the U.S. defense department suggest that the latter are much more vulnerable to bid-rigging than are the former. Subcontracting data reveal that pairs of firms who have been rivals in major non-prototyped competitions have a larger number of subcontracts with one another than do other pairs of firms. The analysis concludes that subcontracts may serve as vehicles for division of the spoils of collusive bidding on prime contracts. 相似文献
