The HRSD, HRSA, SCL-90 scales were psychometrically investigated in a cross-national sample of patients with varieties of non-psychotic symptoms of anxiety and depression. Across the cultural backgrounds the scores obtained from the original versions of these scales are not sufficient statistics. However, latent structure analysis has identified homogeneous subscales for depression (the HRSD) and for discomfort (an SCL subscale). High concurrent validity was found between the subscales of depression, anxiety and discomfort. In international research, inhomogeneity among scale items can be confounded with group differences which are usually ascribed to drug differences.
Transactional Analysis (TA) conceptualizes personality in terms of five functional ego states: Critical Parent (CP), Nurturing Parent (NP), Adult (A), Free Child (FC), and Adapted Child (AC). The present investigation was designed to develop a procedure for the assessment of the relative strength of ego states from the responses of persons who are not familiar with TA theory. Fifteen TA experts assigned ego-state ratings to the 300 items of the Adjective Check List (ACL) with high interjudge agreement being found. Using the judges' mean raft rigs, a system was developed for obtaining ego-state scores for any selected set of ACL adjectives. The use of the system was illustrated by its application to the ACL self-descriptions of 100 university students which were analyzed in terms of "egograms" in which the five functional ego states were expressed relative to one another. A test-retest study involving an additional 154 students demonstrated stable individual differences in ego-state scores. Mean egograms of female and male students did not differ from one another but showed appreciable differences from the expert judges' ratings of the "psychologically healthy person." The potential Usefulness of the procedure in clinical practice and in testing TA theory is discussed.
In this study we examined parent and teacher agreement at the item level of the newly revised Child Behavior Checklist/1 1/2-5 (CBCL/1 1/2-5) and Caregiver-Teacher Report Form/1 1/2-5 (CTRF/1 1/2-5) in 505 preschool children from low-income and predominantly African American families. Parents generally rated more children as having problem behaviors than did teachers. Lack of agreement between parents and teachers at the item level was indicated by low correlation coefficients, kappa values, and co-identification of children with specific behavior problems. High levels of parent-teacher agreement were obtained only when rank orders of problem behaviors were compared. No significant sex effect was found on parent and teacher agreement at the item level. Problem behaviors most often indicated by parents and teachers reflected the roles and responsibilities of parents and teachers in the home and school settings. Our findings suggest informant and setting specificity of parent- and teacher-identified problem behaviors in young children.

Emotional/behavioral problems of 238 deaf Dutch children ages 4-18 years were studied. Parental reports indicated that 41% had emotional/behavioral problems, a rate nearly 2.6 times higher than the 16% reported by parents of a Dutch normative sample. Mental health problems seemed most prevalent in families with poor parent-child communication. Deaf children ages 12-18 showed more problems with anxiety and depression and more social problems than those ages 4-11. Deaf children with relatively low intelligence showed more social problems, thought problems, and attention problems than those with relatively high intelligence. The authors stress the need to get information on deaf children's mental health functioning not just from parents but from other informants such as teachers and the children themselves. An expansion assessment of deaf children, and of special services and treatments for deaf children and adolescents with emotional/behavioral problems, is recommended.

Necrophagous insects, mainly Diptera and Coleoptera, are attracted to specific stages of carcass decomposition, in a process of faunistic succession. They are very important in estimating the postmortem interval, the time interval between the death and the discovery of the body. In studies done with pig carcasses exposed to natural conditions in an urban forest (Santa Genebra Reservation), located in Campinas, State of São Paulo, southeastern Brazil, 4 out of 36 families of insects collected - Calliphoridae, Sarcophagidae, Muscidae (Diptera) and Dermestidae (Coleoptera) - were considered of forensic importance, because several species were collected in large numbers both visiting and breeding in pig carcasses. Several species were also observed and collected on human corpses at the Institute of Legal Medicine. The species belonged to 17 different families, 6 being of forensic importance because they were reared from human corpses or pig carcasses: Calliphoridae, Sarcophagidae, Muscidae, Piophilidae (Diptera), Dermestidae, Silphidae and Cleridae (Coleoptera). The most important species were: Diptera - Chrysomya albiceps, Chrysomya putoria, Hemilucilia segmentaria, Hemilucilia semidiaphana (Calliphoridae), Pattonella intermutans (Sarcophagidae), Ophyra chalcogaster (Muscidae), Piophila casei (Piophilidae); Coleoptera - Dermestes maculatus (Dermestidae), Oxyletrum disciolle (Silphidae) and Necrobia rufipes (Cleridae).
Rotifers present a high diversity in freshwater ecosystems. This study registered 11 genera and 42 species, new records for the Upper Paraná River floodplain. These results showed an increase in rotifer diversity in this ecosystem from 184 to 230 species. Among them some were registered only in the rivers and others in the lagoons. Thirty-seven species occurred in the littoral zone and 34 species in the pelagic; 3 species were registered only in the former zone and 2 species only in the latter. The lagoons presented the greatest richness, probably because of the greater stability, low current velocity, and the extensive aquatic macrophyte banks in the littoral zone of these environments as compared to those of the rivers. The highest number of species in the littoral habitats occurred due to the greater influence of shoreline vegetation, which allows greater habitat diversification. This fact contributed to the occurrence of non-planktonic species in the zooplankton samples.
