The Glass Ceiling Revisited: Determinants of Federal Job Advancement

Using the results of a recent survey of federal employees and focus groups of the same population, this article extends previous research on the existence of a glass ceiling in the federal bureaucracy. Even when controlling for differences between the sexes in human capital factors, work habits, work opportunities, and personal circumstances, women who have been in the federal bureaucracy from zero to 10 years and from 20 to 30 years have not advanced in their professions as successfully as have men. In contrast to and departing from previous research, there is little evidence that a glass ceiling has been experienced among women who have worked in the bureaucracy between 10 and 20 years. Additional findings consistent with past literature include the fact that among women who have faced gender-based barriers, those who chose to have children during their careers have been especially disadvantaged. We conclude that the glass ceiling on the federal level, where apparent, has been multidimensional and quite subtle.     

Expertise in Fingerprint Identification

Although fingerprint experts have presented evidence in criminal courts for more than a century, there have been few scientific investigations of the human capacity to discriminate these patterns. A recent latent print matching experiment shows that qualified, court‐practicing fingerprint experts are exceedingly accurate (and more conservative) compared with novices, but they do make errors. Here, a rationale for the design of this experiment is provided. We argue that fidelity, generalizability, and control must be balanced to answer important research questions; that the proficiency and competence of fingerprint examiners are best determined when experiments include highly similar print pairs, in a signal detection paradigm, where the ground truth is known; and that inferring from this experiment the statement “The error rate of fingerprint identification is 0.68%” would be unjustified. In closing, the ramifications of these findings for the future psychological study of forensic expertise and the implications for expert testimony and public policy are considered.

A novel fluorescence-based method in forensic science for the detection of blood in situ

Full DNA profiles can be generated from just a few cells; however these profiles can be contaminated from other cell types present at the crime scene. We report here on the development of an immunofluorescent technique to spatially locate human-specific blood in situ and also on the ability of this technique to detect individual leukocytes and the DNA contained within them. Four monoclonal mouse anti-human antibodies were evaluated; anti-glycophorin A to detect erythrocytes and anti-CD45, anti-myeloperoxidase (MPO) and anti-histone H1 to detect the nucleated leukocytes. Each antibody was labeled with either Alexa Fluor 488 or 568 for direct application to blood smears which allowed the simultaneous detection of erythrocytes and leukocytes. Furthermore, because histones are DNA binding proteins, the application of anti-histone H1 allowed the detection of DNA within a blood smear. Importantly it was found that full DNA profiles could be achieved after using this method with similar peak area ratios compared to untreated cells. The fluorescent antibodies were found to be human-specific with the exception of anti-histone H1 due to its conserved sequence. However, used in combination with anti-CD45 or anti-MPO the location of DNA from human-specific leukocytes could be detected. The technique was also tested on older blood stains and was still found to be sensitive and cell-specific after 4 months. Following the optimization of the methodology, the fluorescent antibodies were applied to short lengths of black cotton fibres covered with human blood spots. Although the background fluorescence from the cotton was found to be high, erythrocytes and even individual leukocytes could easily be detected, indicating that this technique could be used to detect extremely minute amounts of blood. Used in combination with laser capture microdissection (LCM), this method could be used to pick off individual leukocytes for LCN DNA techniques.     

Family Variables that Mediate the Relation Between Intimate Partner Violence (IPV) and Child Adjustment

This study examined the mediating roles of several family variables in the relation between IPV witnessing and children’s emotional and behavioral problems among 129 low-income, African American children ages 8 to 12. According to the mediational model tested, experiencing or witnessing IPV negatively impacted the following family variables: maternal psychopathology, family cohesion, and relatedness quality, which were subsequently associated with diminished child adjustment. These findings were stronger when child reports were considered and when the outcome variable was internalizing problems. Findings from this study support the value of targeting these variables in the development of culturally appropriate child witness interventions for low-income African American families. Recommendations for future interventions based on study conclusions are offered.
