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.

Discrepancies in Adolescent Romantic Couples' and Observers' Perceptions of Couple Interaction and their Relationship to Depressive Symptoms

We examined discrepancies in adolescent romantic couple members' and observers' perceptions of couples' conversations in order to further understand adolescents' romantic interactions and their association with adolescents' depressive symptoms. We used a video-recall procedure to assess 61 adolescent romantic couples' perceptions of their videotaped conversations with each other. Our results suggest that although couple members and outside observers agreed that adolescent romantic couples' conversations were generally harmonious, adolescent dating partners and observers perceived couples' communications in systematically different ways and perceived inequalities in their interactions. Perceptions of discrepancies in power were more salient in females' perceptions. Both males and females perceived themselves more positively than their partners. Finally, discrepancies in couple members' perceptions of their conversations were somewhat associated with their mental health. Boys who viewed themselves more favorably than their girlfriends viewed them exhibited fewer depressive symptoms. Girls who perceived fewer inequalities between themselves and their boyfriends showed fewer depressive symptoms.     

Evaluation of GLOCK 9 mm Firing Pin Aperture Shear Mark Individuality Based On 1,632 Different Pistols by Traditional Pattern Matching and IBIS Pattern Recognition

Over a period of 21 years, a number of fired GLOCK cartridge cases have been evaluated. A total of 1632 GLOCK firearms were used to generate a sample of the same size. Our research hypothesis was that no cartridge cases fired from different 9‐mm semiautomatic GLOCK pistols would be mistaken as coming from the same gun. Using optical comparison microscopy, two separate experiments were carried out to test this hypothesis. A subsample of 617 test‐fired cases were subjected to algorithmic comparison by the Integrated Ballistics Identification System (IBIS). The second experiment subjected the full set of 1632 cases to manual comparisons using traditional pattern matching. None of the cartridge cases were “matched” by either of these two experiments. Using these empirical findings, an established Bayesian probability model was used to estimate the chance that a 9‐mm cartridge case, fired from a GLOCK, could be mistaken as coming from the same firearm when in fact it did not (i.e., the random match probability).     

Aligning Ideologies and Institutions: Reorganization in the HIV/AIDS Services Administration of New York City

How effective was organizational reform implemented inside one critical New York City health agency? Specifically, we examine the extent to which the reorganization of the HIV/AIDS Services Administration (HASA) into the Medical Insurance Services Administration (MICSA) achieved three goals: (1) realizing synergies among the component MICSA programs; (2) cross‐fertilizing ideas among MICSA agencies; and (3) facilitating HASA operations through the lens of organization change theory. Qualitative methods including interviews, site visits, and document analysis triangulate the effects of the reorganization. Implications for organization change literature are explored, especially highlighting where more theoretical and empirical studies are needed.     

Stray bullets and “mushrooms”: Random shootings of bystanders in four cities, 1977–1988

Bystanders killed by bullets not specifically intended for them have long been a very small part of the homicide problem. But the frequency of press accounts of such killings and woundings has apparently increased nationally in recent years. To test this impression, we compiled all shootings of bystanders hit at random and reported in the published indexes of theNew York Times, theLos Angeles Times, and theWashington Post for 1977–1988, as well as a key word computer search of stories in theBoston Globe. We found a rapid increase in both bystander woundings and killings since 1985 in all four cities. The base rate was quite low, and total bystander deaths appear to comprise less than 1% of all homicides in these cities. Nonetheless, the numbers were large enough to show that most bystanders reported shot in New York and Los Angeles are victims of random shootings into crowds, rather than single stray bullets striking a lone individual mushroom. The reverse was true in Boston and Washington, with the effect of much lower rates of bystanders reported shot in those cities.     

Allelic distribution of nine short tandem repeat (STR), HLA-DQA1, and polymarker loci in an Omani sample population

Allele frequency distributions of nine short tandem repeat (STR) loci, D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D7S820, and D13S317, HLA-DQA1 and polymarker (PM) loci were studied in a sample population from Sultanate of Oman, Middle East. Blood samples were collected from 162 unrelated individuals. For all STR, HLA-DQA1 and PM loci, no deviations from Hardy-Weinberg equilibrium, based on the exact test, were observed. The most discriminating loci were D18S51 (PD=0.966) and FGA (PD=0.964), while the least informative locus is GYPA (PD=0.585). The allele frequency data may be useful in forensic case work.
