Various relationships between predatory dominance and aggressive behavior in Pairs of cats

The experiments were performed on adult male cats selected initially as good mousekillers. Cats were tested in pairs and each pair was introduced separately to the experimental compartment. The attitude toward the partner before and during the predatory competition test as well as superiority in catching and killing the mice, considered as an index of dominance, were registered. In the course of experiment five types of relations between the predatory dominance and aggressive behavior were observed. The concept of dominance as an outcome of several factors was discussed. It was concluded that predatory dominance is not based exclusively on aggressive mechanisms, as it may be formed and sustained without overt aggression.     

Reliability of self-reported service use: Test-retest consistency of children's responses to the Child and Adolescent Services Assessment (CASA)

This paper reports on the reliability of children's responses on the Child and Adolescent Services Assessment (CASA) — a self-report instrument for use with 8– to 18-year-olds that gathers information about services used to address mental health problems. Findings were based on interviews completed by 77 children at a one week test-retest interval. Results showed that reports of lifetime service use were as reliable as were reports of service use in the preceding three months. Children reported restrictive and intrusive services more reliably than services that were provided in their natural environment. Reliability appeared to be associated more strongly with characteristics of the type of service than with characteristics of the child. Children also could report reliably on some details about their encounters with service providers (e.g., length of stay, number of visits, and onset of service use).     

Case illustration: Moving along…and,is change gradual or sudden?

A sequence of analytic sessions of a professional woman in her forties is used to illustrate the moving along process. The material shows a gradual change, where the patient's experience of her sense of agency is altered through a particular kind of interactive sequence. The example is intended to make it clear that the group's view of how change occurs is not strictly or primarily in terms of sudden changes, and that the problem of assessing moments of meeting as well as quantitative and qualitative shifts is one with which the group continues to struggle. © 1998 Michigan Association for Infant Mental Health     

Feeding-based arousal effects on visual recognition memory in early infancy.

Arousal effects on a 1-trial visual recognition paired-comparison task were studied at newborn, 1-month, and 4-month test ages. Infants were tested before and after feeding, with arousal assumed to be lower after feeding. Newborns and 1-month-olds shifted from a familiarity preference before feeding to a novelty preference after feeding. A control group tested only after feeding confirmed that this shift was not due to increased stimulus exposure from the prefeeding test. By 4 months, infants showed novelty preferences independent of feeding. This age by arousal interaction for recognition memory extends previous knowledge by including endogenous arousal with age, stimulus, and length of exposure as contributors to familiarity-novelty preferences. It also extends and provides converging evidence for arousal effects on visual attention in early infancy found previously with preferential looking. A shift from subcortical to cortical dominance is supported.     

The Role of Schools in Outcomes for Youth: Implications for Children's Mental Health Services Research

We explore the role of schools in children's mental health services research. Recent literature has suggested that schools play an important role in delivering services to children and adolescents with emotional and behavioral problems. Research in services research, though, has taken a fairly narrow view of which dimensions of school environments are relevant for inclusion in studies. We suggest that a broader view of school environments is appropriate and potentially beneficial to the field. Using Bronfenbrenner's ecological model as a guide, we conceptualize schools as microsystems. Such an approach suggests that all aspects of school environments (treatment as well as non-treatment) are likely to influence many of the outcomes that children's mental health services research frequently targets (e.g., behavioral problems, problematic peer relationships, academic achievement, school attendance). We review literature from a variety of disciplines to suggest relevant features of schools, with particular attention to the role of peer dynamics within schools. We conclude with implications of this expanded conceptualization of schools for children's mental health services research.     

New polytypes of long-period stacking ordered structures in a near-equilibrium Mg97Zn1Y2 alloy

By atomic-scale high-angle annular dark-field scanning transmission electron microscopy, the long-period stacking ordered (LPSO) structures in a near-equilibrium Mg₉₇Zn₁Y₂ (at.%) alloy have been characterised. In addition to 18R and 14H, new polytypes of LPSO structures are analysed and determined as 60R, 78R, 26H, 96R, 38H, 40H, 108H and 246R. All of these LPSO structures feature AB′C′A building blocks with two Mg layers and three Mg layers sandwiched between them. The Bravais lattices and space groups of new polytypes of LPSO structures were easily determined via the newly introduced method. A structural relationship between the LPSOs is proposed.
