Laryngeal basement membrane thickening is not a reliable postmortem marker for SIDS: results from the Chicago Infant Mortality Study.

It has been suggested that laryngeal basement membrane (LBM) thickening is a pathognomonic postmortem marker for sudden infant death syndrome (SIDS) and is not seen in other causes of explained sudden infant death. To test this hypothesis, we evaluated longitudinal sections of the right hemilarynx taken through the midpoint of the true vocal cord from 129 SIDS cases and 77 postneonatal sudden infant death controls. Using a five-point semi-quantitative scale, maximum LBM thickness (LBMT) for SIDS cases and controls was not statistically different (mean, 2.39 + 0.69 and 2.40 + 0.77, respectively). Likewise, scores based on the average thickness along the entire basement membrane (i.e., "average" score), were not found to be different between SIDS cases and controls. Average and maximum LBMT increased with age in both SIDS cases and controls and were not different between SIDS cases and controls within each age interval. Similar trends in the distribution of maximum and average LBMTs were found between black and Hispanic SIDS and controls; the number of white/non-Hispanic infants was too low for meaningful comparisons. Maximum and average LBMTs were not different in SIDS cases and controls exposed to environmental tobacco compared with unexposed infants. The LBMTs also increased significantly with body weight and length in both SIDS cases and controls. Finally, there were no differences in LBMT in infants intubated prior to death compared with those who were not intubated. From these data, we conclude that LBMT is not pathognomonic of SIDS, is present or absent with equal frequency in SIDS and controls, increases with postnatal age, and does not correlate with passive smoke exposure. Therefore, LBMT should not be used to diagnose SIDS.     

Salient factor score and releasee behavior: Three validation samples

This paper provides an opportunity to observe the application of an actuarial device, used by the United States Parole Commission as an aid in parole selection, to three separate validation samples—each exceeding 1000 cases. Follow-up data for this study were provided through the cooperation of the Federal Bureau of Investigation. In addition, evidence is presented which may shed light on the conflict in the literature regarding whether or not the rate of unfavorable outcome of released prisoners at risk actually declines substantially after the first year (i.e., whether or not the first year after release is really the most critical).Adapted from Report Fifteen, United States Parole Commission Research Unit, August 1977.     

Depressive symptomatology among very early maturing girls

This study investigated whether menarche is associated with depression when its onset is at the very early extreme of the normal age range. Girls who were postmenarcheal at the beginning of the sixth grade, comprising less than 10% of a sample of girls in that grade, were classified as very early maturers; their scores on the Beck Depression Inventory, short form (BDIs), were compared with those of their premenarcheal peers. Additionally, postmenarcheal seventh graders, who comprised 30% of a sample of girls in that grade, were compared to their premenarcheal peers on the BDIs. Results were that postmenarcheal sixth graders were significantly more depressed than their premenarcheal peers, but that postmenarcheal and premenarcheal seventh graders did not differ significantly. The results suggest that very early menarche is associated with higher levels of depression than more normative menarcheal timing.This research was supported by Grant 16034 from the National Institute of Child Health and Human Development.

Psychological mindedness and abstract reasoning in late childhood and adolescence: An exploration using new instruments

This study introduces two new measures of psychological mindedness, applying them in a study of the growth of abstract thinking in children and adolescents in a developmental design. The capacity to achieve psychological understanding of the self and of others involves comprehension of the motives, attitudes, and characteristics of the self and others. Psychological mindedness toward the self (PS) and toward others (PO) may be seen as complex cognitive capacities that should show a pattern of related development in childhood. Three groups of 60 fifth, eighth, and twelfth graders completed two measures of formal operations and two instruments to assess the two components of psychological mindedness. We find that psychological mindedness and abstract thinking both increase significantly with age, although the relationship between them is complex and varies with gender and age. Because the development of abstract reasoning skills does not correlate with the development of psychological mindedness in a simple way, a more complex model is necessary, taking age and gender differences into account. Performance on the two measures of psychological mindedness is found to be largely unrelated, suggesting that these are two different psychological skills. Implications of these findings are discussed, with special reference to education, peer counseling, and psychotherapy.Received Ph.D. from University of Michigan and psychoanalytic training from The Michigan Psychoanalytic Institute.

Timing of menarche,preparation, and initial menstrual experience: Replication and further analyses in a prospective study

The goals of this study were to assess the significance of two timing variables (objective timing of menarche and subjective timing, i.e., the belief—not necessarily true—about one's status as early, average, or late maturing) and two cognitive variables (preparation for menstruation and ego functioning) as predictors of the experience of menarche. Subjects were 92 girls who changed from pre- to postmenarcheal between two test occasions, six months apart. Findings were that subjective timing of menarche and preparation were significant predictors of menarcheal experience, while objective timing and ego functioning were not. The results replicated earlier findings based on cross-sectional analyses. Interpretation of the results suggested some directions for further exploration of determinants of initial menstrual experience.This research was supported by National Institute of Child Health and Human Development Grant 16034 to the first two authors.Received Ph.D. from Clark University.

Bringing Peace into the Room: The Personal Qualities of the Mediator and Their Impact on the Mediation

The training and development of mediators has focused primarily onenhancing mediators' technical skills and increasing their understandingof the theory behind the practice of mediation. This article focuses on athird aspect of the development of mediators - namely, their personalcharacteristics. The authors contend that a mediator'spresence - more afunction of who the mediator is than what he or she does - has a profoundimpact on the mediation process. Drawing on analogies fromresearch in the physical and social sciences, the article suggests that themost subtle influences of the mediator's affect and manner may in fact bepowerful influences in helping the mediator bring peace into theroom.
