Children's memory for phonemically confusable and nonconfusable letters: changes with age and reading ability     

G L Bisanz  J P Das  G Mancini 《Child development》1984,55(5):1845-1854

This experiment focused on differences that occur with age and reading skill in the use of phonemic codes in short-term retention tasks where stimuli were presented visually. In 1 condition, individuals recalled 6-letter strings composed of rhyming and nonrhyming letters after a 15-sec delay under conditions that permitted phonemic coding and rehearsal. 2 other conditions were designed to suppress (a) rehearsal of certain types of phonemic codes in the delay interval and (b) both phonemic coding at stimulus presentation and rehearsal. Subjects were grade 2 average readers matched in reading skill with grade 4 disabled readers, grade 4 average matched with grade 6 disabled, and grade 6 average matched with grade 4 superior readers. Average readers showed a decrease in errors with age in all 3 conditions, although performance was always better in the nonsuppression condition. In the latter, memory for nonrhyming letters was always better than memory for rhyming letters. Differential use of phonemic codes by good and poor readers in grades 4 and 6 was less than that found in previous research with younger children. Finally, by comparing the performances of grade 2 average with grade 4 disabled readers and grade 4 average with grade 6 disabled readers, the developmental lag hypothesis of reading disability was examined. Problems with testing the hypothesis are discussed.  相似文献

Multivariate alternatives to regression analysis in the evaluation of salary equity-parity     

Richard D. Carter  Rhea S. Das  Andrea H. Garnello  Richard C. Charboneau 《Research in higher education》1984,20(2):167-179

The analysis of salary equity-parity in institutions of higher education typically involves the use of multiple regression analysis to determine predicted salary and the residual differences between predicted and actual salary. Multiple regression analysis forces the variable weights throughout the salary structure to be uniform, permits only one criterion or dependent variable to be examined at a time, restricts the coordinates to those provided by the variables as measured, and as customarily used, treats qualitative or discrete variables as if they were continuous, assuming ordinality of the numbers used. Two multivariate alternatives to regression analysis are presented, canonical analysis and multiple discriminant analysis, both of which define new coordinate systems for evaluation of dimensions underlying salary decisions.Presented at the 23rd Annual Forum of the Association for Institutional Research, Toronto, May 1983.  相似文献   

Counselling people with addictive behavior     

Ajit K. Das 《International journal for the advancement of counseling》1990,13(2):169-177

A general framework for understanding addictive behaviors (involving chemical substances as well as other forms of compulsions) is presented with special reference to excessive drinking, overeating and compulsive gambling. Treatment procedures for each of these problem behaviors are described and some general conclusions drawn for dealing with other forms of addictions.Paper presented at the XIII^th IRTAC Conference at Calgary, August 14–18, 1988.  相似文献

Maternal Working Models of Attachment, Marital Adjustment, and the Parent-Child Relationship   总被引：2，自引：0，他引：2  

Rina Das Eiden  Douglas M. Teti  Kathleen M. Corns 《Child development》1995,66(5):1504-1518

This study examined the connection between maternal working models, marital adjustment, and the parent-child relationship. Subjects were 45 mothers who were observed in problem-solving interactions with their 16–62-month-old children ( M = 33 months). Mothers also completed the Attachment Q-set, the Adult Attachment Interview, and a marital adjustment scale. As predicted, maternal working models were related to the quality of mother-child interactions and child security, and there was a significant relation between marital adjustment and child security. Maternal working models and marital adjustment were also associated interactively with child behavior and child security. Among children of insecure mothers, child security scores were higher when mothers reported high (vs. low) marital adjustment. No relation between child security scores and mothers' marital adjustment was found among children of secure mothers. These results suggest that maternal working models influence parenting and child adjustment well beyond infancy, to which period the few existing studies of adult attachment have been restricted. The results also suggest that interactions between maternal working models and the marital adjustment on child behavior and attachment security need to be more closely examined.  相似文献

Chlorella vulgaris triggers apoptosis in hepatocarcinogenesis-induced rats     

Emey Suhana Mohd Azamai  Suhaniza Sulaiman  Shafina Hanim Mohd Habib  Mee Lee Looi  Srijit Das  Nor Aini Abdul Hamid  Wan Zurinah Wan Ngah  Yasmin Anum Mohd Yusof 《Journal of Zhejiang University. Science. B》2009,10(1):14-21

Chlorella vulgaris (CV) has been reported to have antioxidant and anticancer properties. We evaluated the effect of CV on apoptotic regulator protein expression in liver cancer-induced rats. Male Wistar rats (200∼250 g) were divided into eight groups: control group (normal diet), CDE group (choline deficient diet supplemented with ethionine in drinking water to induce hepatocarcinogenesis), CV groups with three different doses of CV (50, 150, and 300 mg/kg body weight), and CDE groups treated with different doses of CV (50, 150, and 300 mg/kg body weight). Rats were sacrificed at various weeks and liver tissues were embedded in paraffin blocks for immunohistochemistry studies. CV, at increasing doses, decreased the expression of anti-apoptotic protein, Bcl-2, but increased the expression of pro-apoptotic protein, caspase 8, in CDE rats, which was correlated with decreased hepatoctyes proliferation and increased apoptosis as determined by bromodeoxy-uridine (BrdU) labeling and terminal deoxynucleotidyl transferase mediated dUTP nick-end labeling (TUNEL) assay, respectively. Our study shows that CV has definite chemopreventive effect by inducing apoptosis via decreasing the expression of Bcl-2 and increasing the expression of caspase 8 in hepatocarcinogenesis-induced rats.

Revisiting the "simple view of reading" in a group of children with poor reading comprehension     

Georgiou GK  Das JP  Hayward D 《Journal of learning disabilities》2009,42(1):76-84

According to Gough and Tunmer's Simple View of Reading, Reading Comprehension = Decoding (D) x Listening Comprehension (C). The purpose of this study was to evaluate the model with a sample of First Nations children, known to have average decoding and listening comprehension but poor reading comprehension. In addition, the authors examined the contribution of naming speed and phonological awareness to reading comprehension beyond the effects of D and C. Consistent with the findings of previous studies, the children exhibited poor reading comprehension despite average performance in decoding and listening comprehension, a finding that challenges the simple view of reading. The results also revealed that an additive model (D + C) fitted the data equally well as a product model (D x C). Neither naming speed nor phonological awareness accounted for unique variance.  相似文献
