In this study, parent-child interaction in two carefully matched subgroups-school-age boys with learning disabilities (LD) who showed a discrepancy between their verbal IQ and performance IQ and had more extensive difficulties in higher-level language abilities (VIQ < PIQ, n = 8) and boys with LD who did not manifest a discrepancy between verbal IQ and performance IQ (VIQ = PIQ, n = 8), were investigated. The effects of the child's language problems on child task performance and on the quality of maternal communication were analyzed in a mother-child problem solving task. Children in the VIQ < PIQ group were found to be less successful on the task than children in the VIQ = PIQ group, and their mothers exhibited lower communication clarity in their instructions than the mothers of the children in the VIQ = PIQ group. An interesting interaction effect was found for communication deviances. For mothers in the VIQ < PIQ group the extent of deficient communication increased from the monologue to the dialogue situation, whereas communication deviances decreased for mothers in the VIQ = PIQ group. Three possible models are discussed in light of the differences between the subgroups. 相似文献

We report physicochemical characteristics of various kinds of liquid milk commercially available in Pakistan in comparison with those of fresh natural milk from animals. Milk samples were collected from local markets at Peshawar, Pakistan,and analyzed for their physical features, including moisture, total solids, specific gravity, conductivity, viscosity and titratable acidity (lactic acid equivalent), and chemical components and macro-minerals, including total protein, casein, lactose, ash and minerals (Na, K and Mg). These items were compared with the physicochemical characteristics of the fresh natural milk samples from buffalo, cow and goat. The results were also compared with reported nutritional quality of milk from various countries and World Health Organization (WHO) standards. We found that all the physical features and chemical components of commercially available milk in Pakistan markets meet WHO's requirements, except for Na, K, Ca and Mg, which are below the standards. 相似文献

INTRODUCTION The difficulties associated with large-scaleproduction of biotherapeutics provide a constantchallenge to the biotechnology industry. FDA hadadded “therapeutic DNA plasmid vectors” to the listof well-characterized biotechnology product (DoHHs,1996), and gene therapy has moved rapidly fromlaboratory scale to clinical trials. It is urgent to de-velop new protocols to obtain high-quality plasmidswith high yields and minimal or no contamination ofRNA and chromosomal D… 相似文献
