Research on the mechanisms by which interparental conflict (IPC) affects child depression suggests that both parenting and children’s conflict appraisals play important roles, but few studies have explored the role of general cognitive style or included both parenting and cognitions in the same design. Moreover, the effects of IPC on minority children are not well understood. In this longitudinal study, parenting was examined as a mediator of the relation between increasing IPC and change in depression. General cognitive style was included as a moderator. The combined influence of parenting and cognitions was also explored. A racially and ethnically diverse sample of 88 fifth and sixth graders from two urban schools reported their cognitive style, depressive symptoms, and perceptions of conflict and parenting at two time points separated by one year. Parental warmth/rejection mediated the relation between IPC and depression, and general cognitive style acted as a moderator. Parenting, cognitive style, and IPC did not significantly interact to predict change in depression over time. Findings indicate that both parenting and children’s general cognitive style play a role in understanding the impact of increasing IPC on children’s well-being.  相似文献

Histological analysis of the viscera in experimental poisoning with psilocybin-containing mushrooms showed nonspecific changes in all examined organs, presenting as expressed hemocirculatory disorders and intracellular dystrophy. Quantitative histochemical analysis showed appreciable shifts in the activities of enzymes involved in the cytoplasmic and mitochondrial redox processes and of specific enzymes involved in nerve tissue metabolism. This may reflect some features in the direct effects of narcotic alkaloids contained in psilocybin-producing mushrooms.  相似文献

Prostate specific antigen (PSA, also known as p30), a glycoprotein produced by the prostatic gland and secreted into seminal plasma, is a marker used for demonstrating the presence of seminal fluid. Methods for the detection of PSA include Ouchterlony double diffusion, crossover electrophoresis, rocket immuno-electrophoresis, radial immunodiffusion, and ELISA. The extremely sensitive ELISA technique can detect PSA in concentrations as low as approximately 4 ng/mL. However, all these techniques are cumbersome and time consuming to perform in forensic laboratories, especially when only a few samples per week are processed. Various membrane tests are currently used in clinical settings to screen a patient's serum for the presence of PSA at levels greater than 4 ng/mL. In this study we evaluated three immunochromatographic PSA membrane tests by analyzing semen stains stored at room temperature for up to 30 years, post-coital vaginal swabs taken at different time after intercourse, semen-free vaginal swabs, and various female and male body fluids, including urine. The data demonstrate that PSA membrane test assays offer the same sensitivity as ELISA-based tests and provide a rapid approach for the forensic identification of seminal fluid. Furthermore, when the supernatant from a DNA extraction is used for the assay, there is essentially no DNA consumption for determining the presence of PSA in a forensic sample.  相似文献

Distributive and Procedural Justice in Seven Nations   总被引:1,自引:0,他引:1  
The paper examines the impact of distributive justice and procedural justice variables on judgments in seven countries (Bulgaria, France, Hungary, Poland, Russia, Spain, and the United States). Subjects were presented with each of two experimental vignettes: one in which the actor unsuccessfully appeals being fired from his job and one in which the actor unsuccessfully goes to an employment agency to seek a job; they were asked to rate the justness of the outcome and how fairly the actor had been treated. The vignettes manipulated deservingness and need of the actor (distributive justice factors) and impartiality and voice in the hearing (procedural justice factors). Four hypotheses were tested: first, a distributive justice hypothesis that deservingness would be more important than need in these settings; second, a procedural justice hypothesis that the importance of voice and impartiality vary depending on the nature of the encounter and the forum in which it is resolved; third, because of their recent socialist experience, Central and Eastern European respondents make greater use of need information and less use of deservingness information than Western respondents; and fourth, that distributive justice and procedural justice factors interact. The distributive justice hypothesis is supported in both vignettes. The procedural justice hypothesis receives some support. Impartiality is more important in the first vignette and voice is more important in the second vignette. The interaction hypothesis was not supported in the first vignette, but does receive some support in the second vignette. The cultural hypothesis is not supported in either vignette. The implications for distributive and procedural justice research are discussed.  相似文献

Postmortem redistribution of morphine and its metabolites   总被引:2,自引:0,他引:2  
The postmortem redistribution of morphine, morphine-3-glucuronide, morphine-6-glucuronide and total morphine was assessed in 40 heroin-related deaths. In blood taken from subclavian, heart, and femoral regions, concentrations of morphine and its metabolites were similar. While there was a trend for higher concentrations in heart blood, when compared with femoral or subclavian blood, this was not significant. There was also no significant difference in concentrations between admission and autopsy blood in which the postmortem interval was on average 59 h. From our observations, significant postmortem redistribution of morphine and its metabolites seems unlikely.  相似文献
