In the present study, two mentally retarded children with high rare stereotypic responding were hospitalized in a university medical school setting and treated with punishment and differential reinforcement of other behavior (DRO). Differential impact of the two treatment conditions was assessed using an alternating treatments design that incorporated the use of condition-specific discriminative stimuli. Experimental control was established through the use of a separate condition of no treatment. Results of the study indicated that for both subjects, all conditions were clearly discriminated and that punishment procedures were more effective for suppressing stereotypies than DRO. Six-month follow-up data were reported. Implications for future research utilizing the alternating treatments design were also discussed. © 1981.

The same aminoglycoside 2'-adenylyltransferase was isolated from four gram-negative species which were among a random group of gentamicin-resistant isolates from the same hospital. The enzyme was partially purified from a crude extract which also contained a second modifying enzyme identified as APH(3')-I. The substrate range of the new aminoglycoside 2'-adenylyltransferase included the newer aminoglycosides sisomicin and amikacin, but showed much-reduced activity against gentamicins C2 and Cla. The pH optimum was 7.8 to 8.0 for every substrate, and the molecular weight of the enzyme molecule was estimated at approximately 29,000. Genetic experiments clearly established that both enzymes were expressed by a conjugative plasmid.

SummaryThin beds composed mainly of quartz and albite occur interstratified with epiclastic rocks in a thick marine Early Permian sequence in the eastern part of the New England Fold Belt, eastern Australia. The sequence has suffered very low grade regional metamorphism and the quartz-albite rocks retain few primary textural features. A pyroclastic origin for these rocks is argued on the basis of inherited sedimentary characters and their distinctive mineralogical and chemical composition, and it is suggested that they accumulated as glass-rich ash-fall tuffs. The present chemical composition of the quartz-albite rocks suggests the tuffs may have initially altered to zeolitic assemblages. Similar quartz-albite rocks, perhaps misidentified as chert or siliceous siltstone, probably occur in other low-grade metamorphic sequences, the progenitors of which accumulated adjacent to active magmatic arcs.

This paper describes the results from an extensive series of experiments aimed at enhancing the skill of the Australian Numerical Meteorology Research Centre (ANMRC) limited area analysis/forecast system. Significant increases in model performance were achieved, in the sense of reducing S1, skill scores and in forecasting precipitation, in three ways: (1) improved data base since the beginning of FGGE; (2) the application of a more realistic lateral boundary specification, particularly nesting within a hemispheric forecast model; and (3) the reduction of truncation errors by either decreasing the grid spacing or (more efficiently) employing higher order difference operators. The improvement in skill is sufficiently large to suggest that when implemented operationally the quality of routine prediction of synoptic scale patterns over the Australian region will be considerably improved.

A procedure is described for isolating photosynthetically active rhodoplasts ("red algal chloroplasts") from the marine alga Griffithsia monilis. The rhodoplasts exhibited rates of CO(2) fixation and CO(2)-dependent O(2) evolution in the order of 200 micromoles per milligram chlorophyll a per hour when illuminated with red or green light and were approximately 80% intact. The response of the rate of photosynthesis to the inorganic phosphate and pyrophosphate concentrations in the medium was qualitatively similar to that previously reported for spinach chloroplasts. Osmotically shocked rhodoplasts evolved O(2) from ferricyanide in red, but not in green, light and were completely uncoupled. Rhodoplast envelope rupture appeared to be accompanied by phycobilisome loss from the thylakoids.

Long‐term variations in the intertidal algal flora of the entire rock platform at Plantation Point, Jervis Bay, are described by May (1981). The study now reported presents similar long‐term changes in the flora of a subtidal region of the same headland, observed within the same period of time. This first detailed report of subtidal macroalgal communities in New South Wales describes a several‐year study of the benthic communities along a transect in the upper sublittoral region of a rocky headland at Plantation Point, Jervis Bay. Eighty‐nine species of algae were recorded, five of which were previously unrecorded for New South Wales. The area studied is dominated by the large brown algae Ecklonia radiata and Phyllospora comosa, large areas of which were cleared periodically by storms. Turf, shade and crustose coralline algal communities also were present. Storms, seasonal variation and longer term changes all affected the abundance and distribution of the algal species growing along the transect and hence the floristic composition of the area.

Under certain restrictions on the boundaries f(n) and g(n) logarithmic asymptotes of these probabilities are found in the case when the ξk satisfy (respectively) a two-sided or a one-sided Cramer condition.

The relative contribution of self-monitoring and competing response practice to the effectiveness of the Azrin and Nunn (1973, 1977) habit-reversal procedure was investigated in two children exhibiting nervous tics. A multiple baseline design across settings was employed for each child and the reliability of self-monitoring was determined. Results indicated that both children were capable of reliable self-monitoring and that self-monitoring alone was sufficient to reduce tics in one of the children. For the other child, who presented a longer history of tics, it was necessary to include competing response practice with the self-monitoring. For both children, change was setting specific. Issues of generalization were discussed.

The present study examined the utility of the alternating treatments design by comparing physical restraint and positive practice overcorrection to a "no treatment" condition in the reduction of stereotypic behavior. Both active treatments were more effective than no treatment, and the treatments were differentially effective for different children. © 1981 Association for Advancement of Behavior Therapy.

SUMMARYThe major type I insert sequence for the 28S rRNA genes ofDrosophila melanogasterhas been mapped within the chromosomes using a probe synthesized from a cloned sequence containing the entire 5·4 kb segment. The genomic distribution was shown to be complex in that the insert sequence occurred next to many different types of sequences, in addition to occurring as an insert in the 28S rRNA genes of theXchromosome.In situhybridization of mitotic chromosomes showed most of the insert units not contained in the ribosomal genes to be located near the ribosomal gene cluster on theXchromosome. Additional sites were detected in polytene chromosomes in region 102C, 8–12 and in the hetero-chromatin of the autosomes.

FLOW-CYTOMETRIC MEASUREMENTS of cell DNA content or narrow-angle light scatter (NLS) can provide a basis for discriminating neoplastic from non-neoplastic cells by identifying differences in DNA content and cell size. Flow-cytometric analyses of many human neoplasms have been previously reported (Barlogie et at., 977, 1978) showing aneuploidy in 80-90% of non-lymphoid solid tumours and 40- 60% of non-Hodgkin's lymphomas. In leukaemias, and multiple myelomas with and aneuploid tumour clone, the percentage of neoplastic cells in marrow or blood determined by DNA content correlates well with quantitation based on histologic smears (Barlogie et al., 1977; Latreille et al., 1980; Andreeff et al., 1980) but such a comparison has not been made on cell suspensions from solid tumours.

The major satellite of M. r. robustus DNA has been isolated in a Ag+ -CS2S04 gradient.has a of 1� 710 gjcm3 compared with 1� 697 gjcm3 for the bulk of the DNA, and accounts for about 10% of the total DNA. Sequence heterogeneity within the satellite was shown by an increase in density to 1�715 gjcm3 and by a reduction of 12�C in the temperature of denaturation (Tm) after renaturation. The satellite was found to occur in the centromeric regions of all chromosomes. This pattern of distribution was essentially duplicated in the genomes of other members of the wallaroo group. A polymorphism for a major block of the sequences on chromosome 5 occurred in both M. r. erubescens and M. antilopinus.
