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.

La vie à l'assemblée,angle mort de la science politique française

Legislative studies are an important branch of political science in the United States and most European countries, but French scholars, during the past twenty years, have somewhat neglected the analysis of parliamentary behaviour. This research note argues that this low interest in the life of national and local assemblies can be explained by the conjunction of two factors: on the one hand, the weakness of parliamentary intervention in France, which results from the increasing importance of the executive branch, at the expenses of assemblies, in the formulation of public policy; on the other, the emancipation of political science from law as well as its openness to the sociological approach during the 1980s and 1990s.     

Children’s and parents’ involvement in care order proceedings: a cross-national comparison of judicial decision-makers’ views and experiences

This paper presents the views of judicial decision-makers (n = 1794) in four child protection jurisdictions (England, Finland, Norway, and the USA (California)), about whether parents and children are provided with appropriate opportunities to participate in proceedings in their countries. Overall, the study found a high degree of agreement within and between the countries as regards the important conditions for parents’ and children´s involvement, although the four systems themselves are very different. There was less agreement about children’s involvement than parents’, and the court decision-makers from Norway and Finland were more likely to express doubts about this. Nevertheless, the main message from the judicial decision-makers is that they are relatively satisfied as to how parents’ and children´s involvement is handled in their countries. Whether or not this confidence is justified, the emphasis on achieving effective involvement of children and parents in court proceedings is likely to grow, with major implications for the workers, decision-makers and agencies involved.     

Predicting daily-life antisocial behaviour in institutionalized adolescents with Transgression-related Implicit Association Tests

This study investigated whether implicit attitude (IA) and implicit self-concept (ISC) towards transgression predicted daily-life antisocial behaviour (ASB) in institutionalized adolescents. Eighty-seven adolescents completed two Implicit Association Tests (IAT) assessing IA and ISC towards transgression, and reported four times a day during eight days the intensity of their ASB. Staff members concurrently reported the intensity of each adolescent’s ASB. Adolescents filled in the Inventory for Callous-Unemotional Traits and answered a semi-structured interview assessing conduct disorder. Multilevel regression analyses confirmed that adolescents’ ISC towards transgression significantly predicted their self - and staff-reported ASB over and above conduct disorder and callous-unemotional traits. However, adolescents’ IA towards transgression did not predict their ASB. Results indicate that ISC towards transgression is a reliable predictor of daily-life ASB in institutionalized adolescents. These results suggest that transgression-related ISC represents a promising target for ASB prevention in institutionalized adolescents.     

Neighborhood Disadvantage and Neuropsychological Functioning as Part Mediators of the Race–Antisocial Relationship: A Serial Mediation Model

Objectives

We test a serial multiple mediation model in which the relationship between ethnicity and antisocial behavior is sequentially mediated by disadvantaged neighborhoods and impaired neuropsychological functioning.

Methods

Parental and self-report measures of antisocial behavior were assessed in a community sample of 341 adolescent males and females. Neighborhood disadvantage was assessed from census data. Neuropsychological functioning was evaluated using a computerized battery. Separate serial multiple mediation models were tested using non-executive functioning and executive functioning.

Results

The serial mediation model for executive functioning was supported, with the pathway from race to antisocial behavior through neighborhood disadvantage and executive functioning in serial accounting for 10.8% of the total effect of race on antisocial behavior.

Conclusions

Findings support social neurocriminology theory by integrating neighborhood disadvantage and executive functioning as sequential mediators of the race–antisocial relationship. To our knowledge, these are the first findings to explain the race–antisocial relationship in terms of connected social and neuropsychological processes. While this pathway is significant, the effect is still relatively small and thus should be understood as one of many mechanisms through which race may affect antisocial behavior. From a translational science standpoint, the identification of neurocognitive mechanisms by which neighborhood disadvantage predisposes to antisocial behavior suggests the potential benefits of cognitive enhancement techniques to remediate the negative effects of adverse neighborhoods on brain functioning in at-risk minority groups.

     

Evaluation of the self-heating tendency of vegetable oils by differential scanning calorimetry

The evaluation of the self-heating propensity of a vegetable (or animal) oil may be of significant importance during the investigation of a fire. Unfortunately, iodine value and gas chromatographic-mass spectrometric analysis do not lead to meaningful results in this regard. To the contrary, differential scanning calorimetry (DSC), which does not measure the chemical composition of the oil, but rather its thermodynamic behavior, produces valuable results. After a thorough literature review on the autooxidation of vegetable oils, several oils with different self-heating tendencies were analyzed using a Mettler-Toledo differential scanning calorimeter DSC 25 between 40 degrees C and 500 degrees C. Analyses were carried out both under air and nitrogen atmosphere to identify the phenomena due to autooxidation reactions. Using DSC, it was possible to observe the induction period of the oil (when available), the three different exothermic events, and the autoignition temperature (relatively independent of the oil type).
