Behavioural inhibition and hyperactivity: a commentary from alternative perspectives     

J. P. Das  Timothy Papadopoulos 《欧洲特需教育杂志》2013,28(2):183-195

Attention disorders in the school population include attention deficit, hyperactivity and conduct disorders. A key concept for distinguishing hyperactive from attention disorders is behavioural inhibition as advocated by Barkley, a prominent American researcher. However, the concept itself needs to be understood because, as argued in this paper, there are two kinds of inhibition: Pavlov's original concept and the American one. These should be differentiated if the abnormal conditions associated with attention and hyperactivity are to be rationally connected to cognitive characteristics, rather than to be solely based on clinical symptoms and behavioural ratings. We suggest a consensus on the concept of inhibition and a unified view of attention disorders integrating cognitive and behavioural manifestations. Finally, the importance of basing remediation on a theoretically supported and rationally derived set of cognitive training tasks for the amelioration of inattention and hyperactivity is offered.  相似文献   

“Save our students”: contesting discourses of racist attacks against Indians down under     

Purba Das 《亚洲交流杂志》2016,26(1):1-13

This paper seeks to understand the dominant civic discourses of accusation of racism leveled against the Australians as expressed by the victims of racist attacks and Indian Government officials in the Times of India and Outlook India news magazines. The aim of the paper is to understand how the logics of the discourses have constituted the racially motivated attacks on the Indian diaspora in Australia, and how the nationalistic sentiments are fostered among the diasporic Indians and the Indians in India. The paper argues that there is a mutual production of diasporic and homeland nationalism in the face of a crisis that hits the Indian diaspora in Australia. This analysis also brings to fore the ideology of multiculturalism in Australia.  相似文献   

The human dimension of development in India     

Ajit K. Das  Sharon F. Kemp 《International journal for the advancement of counseling》1994,17(3):193-204

This paper provides an overview of the level of economic development in India, with a brief explanation of the factors that have impeded rapid growth of the economy. Against this background information, the paper focuses on some social programs undertaken by government and non-governmental agencies to help the most vulnerable segments of society to deal with the adverse effects of industrialization and urbanization and to share in the benefits of economic development.  相似文献   

QTL analysis for some quantitative traits in bread wheat     

Pushpendra KG  Harindra SB  Pawan LK  Neeraj K  Ajay K  Reyazul RM  Amita M  Jitendra K 《Journal of Zhejiang University. Science. B》2007,8(11):807-814

Quantitative trait loci (QTL) analysis was conducted in bread wheat for 14 important traits utilizing data from four different mapping populations involving different approaches of QTL analysis. Analysis for grain protein content (GPC) sug- gested that the major part of genetic variation for this trait is due to environmental interactions. In contrast, pre-harvest sprouting tolerance (PHST) was controlled mainly by main effect QTL (M-QTL) with very little genetic variation due to environmental interactions; a major QTL for PHST was detected on chromosome arm 3AL. For grain weight, one QTL each was detected on chromosome arms 1AS, 2BS and 7AS. QTL for 4 growth related traits taken together detected by different methods ranged from 37 to 40; nine QTL that were detected by single-locus as well as two-locus analyses were all M-QTL. Similarly, single-locus and two-locus QTL analyses for seven yield and yield contributing traits in two populations respectively allowed detection of 25 and 50 QTL by composite interval mapping (CIM), 16 and 25 QTL by multiple-trait composite interval mapping (MCIM) and 38 and 37 QTL by two-locus analyses. These studies should prove useful in QTL cloning and wheat improvement through marker aided selection.  相似文献   

Assessment of attention in school children: teachers' ratings related to tests of attention     

Timothy C. Papadopoulos  J. P. Das  H. M. Nelly Kodero  Veronica Solomon 《欧洲特需教育杂志》2013,28(1):15-32

The paper provides (1) a teacher-administered rating instrument for inattention without confounding the rating with hyperactivity and conduct disorder, and (2) evidence that the ratings correlate with the scores obtained from cognitive tests of attention. In Study I, the first objective was to investigate the construct validity and the inter-rater reliability of the Attention Checklist (ACL) by factor analysing the teacher ratings of 110 Grade 4 children, obtained by using the ACL. The second objective was to investigate the predictive validity of the ACL by examining the relationship between the scores obtained for the participants from teachers' ratings using the ACL and the scores obtained by participants in the lab-type attention tests. The results of factor analysis showed that a single factor labelled ‘inattention’ underlies the 12 items in the ACL. Examining the differences in performance on attention tests, the ‘low attention’ children as rated by the teachers on the ACL scored lower than the ‘high attention’ children on the objective tests of attention. These findings were replicated in Study II, which was conducted to test further the construct validity and predictive validity of the ACL. This time, only those two tests (Auditory Attention and Visual Attention) that had shown relatively poor discrimination between the high and low attention groups in Study I were, again, administered to another cohort of 97 Grade 4 children, as it was our intention to further challenge the reliability of the ACL. Overall, the results of both studies suggest that comprehensive assessment of attention skills should include both ACL and objective measures of selective attention.  相似文献   

UNIVERSITY‐BASED ADULT DAY CARE CENTER FOR RESEARCH AND TRAINING: DESIGN,FUNDING, AND PROGRAMMATIC ISSUES     

Shirley S. Travis  Puspa Das 《Educational gerontology》2013,39(6):557-565

In the early 1980s, the College of Human Resources at Virginia Polytechnic Institute and State University began a visioning process to plan its educational agenda for the 21st century. One of the more pressing issues targeted for educational intervention was community‐based long‐term care. Ten years later, a licensed, Medicaid‐certified adult day health center is fully operational on the university campus, providing a myriad of research, teaching, and public service opportunities for faculty and students. Center design, funding, and programmatic issues are discussed.  相似文献   

External quality assessment for the RIA of thyroid related hormones: Second phase     

Ajay Kumar  D. H. Shah  M. G. R. Rajan  U. R. Thakare  S. M. Sharma 《Indian journal of clinical biochemistry : IJCB》1992,7(2):159-164

An external quality assessment was conducted to assess the performance of various laboratories for RIA of thhyroid related hormones in two phases. In the first phase thirty five laboratories participated. At the end of first phase a meeting cum workshop was organised to discuss the results of first phase, difficultires faced by the participants and pinpoint the short oming. A second phase was then initiated with an objective of improvement in the performance, if any, where twelve samples from four pools were distributed to twenty four laboratories who participated for the second phase. The overall return of the results increased significantly from 71.8% (1586/2208) for the first phase to 92.4% (732/792) for the second phase. The inter laboratory %CV for T₃, T₄ and TSH were lower during the second phase (30.6%, 19.0% and 31.6% respectively) as compared to those observed during first phase (36.3%, 22.7% and 52.8% respectively). Similarly, there was an improvement in reproducibility of ALTM as %CV for T₃, T₄ and TSH decreased from 6.0%, 9.8% and 13.4% respectively to 4.5%, 4.6% and 8.5% respectively. The individual performances of the participating laboratories viz. bias, variability of bias and imprecision also showed a trend towards improvement as percent laboratories having desirable or acceptable results for T₃, T₄ and TSH increased from 10.7%, 60.7% and 0.0% respectively to 20.8%, 66.7% and 22.2% respectively. External quality assessment thus appears to be beneficial in assessing the performane of a laboratory in comfparison with other laboratories and indeed helps in improving the performance.  相似文献   

Astudy on mycobacterial proteins in the serodiagnosis of tuberculosis using ELISA and western blot     

Ajay Kumar  T. A. Venkita Subramanian  Usha P. Sharma 《Indian journal of clinical biochemistry : IJCB》1992,7(2):165-168

Protein fraction termed P₂ was obtained from sonicates of Mycobacterium smegmatis, subjected to ammonium sulphate precipitation. P₂ fraction was further fractionated into 4 fractions (PeakI-IV) by DEAE cellulose ion-exchange chromatography. ELISA was performed on the sera of 104 tuberculous cases and 62 controls, using P₂ fractions Peak I as test antigens. Though the mean ELISA values in tuberculous cases were higher than the controls, no statistically significant difference was found between the two. Antigens P₂, Peak I and IV were tested on Western blots with pooled sera from tuberculous cases as well as controls. P₂ fraction, Peak-I and IV were separated on PAGE-SDS, electroblotted onto nitrocellulose Sheets and the blots were subjected to ELISA. Peak IV appeared as a single band (M.W. 55,000). P₂ fraction exhibited some discriminatory bands on development of blots.  相似文献
