Conventional methods of differentiating reading disability (RD) caused by deficits in decoding skills or comprehension from poor reading performance caused by inconsistent attention associated with attention-deficit/hyperactivity disorder (ADHD) have produced equivocal results. This study presents a model of differential diagnosis of attentional problems and RD that differs from these conventional approaches. The new diagnostic procedure uses intraindividual differences seen in the performance of at-risk learners on tasks related to reading that vary in their sensitivity to the sustained attention required for successful performance. The hypothesis is that children with inconsistent attention would perform more poorly on tests that require sustained attention, such as listening comprehension, than on tests that are more tolerant of inattention, such as reading comprehension. Such differences would not be seen in the test scores of children who have only RD, because their performance is determined more by the difficulty level of the reading tests than by the degree of sensitivity of the task to attention. The validity of this new model was evaluated by determining the capability of the differences seen in the scores of tests that differ in their sensitivity to sustained attention to predict the degree of inconsistency in sustained attention as measured by a continuous performance test. The data obtained from 39 children who are at risk for RD suggest that this is a viable model. 相似文献

Repeated blood transfusion in beta thalassemia major patients may lead to peroxidative tissue injury by secondary iron overload.
In the present study, 72 children with beta thalassemia major were included. Serum levels of total lipid peroxides, Iron,
Total Iron Binding Capacity, Copper, Zinc, Vitamin E, plasma Total Antioxidant Capacity, activity of Erythrocyte Superoxide
Dismutase, were measured. The findings were compared with 72 age matched healthy controls irrespective of sex. A significant
increase in the levels of lipid peroxide and Iron (p<0.001), whereas, significant decrease in the levels of vitamin-E, Total
Antioxidant Capacity and Total Iron Binding Capacity (p<0.001) was observed. Serum Zinc was significantly increased (p<0.001)
with significant decrease in the levels of copper (p<0.001). Non Significant increase in the activity of Erythrocyte Superoxide
Dismutase (p>0.05) was found in the patients when compared with controls. This suggest that oxidative stress and reduced antioxidant
defense mechanism play an important role in pathogenesis of beta thalassemia major. 相似文献

Whether the simple view of reading (SVR) as incorporated in the componential model of reading (CMR) is applicable to other orthographies than English was explored in this study. Spanish, with transparent orthography and Chinese, with opaque orthography were selected because of their diverse characteristics. The first part reports a study of students from grades 2 and 3, whose home language and medium of instruction was Spanish, and were administered tests of decoding, listening, and reading comprehension. A comparison group of 49 children from Grade 2, 54 children from Grade 3, and 55 children from Grade 4, whose home language and instruction was English, were also administered tests of decoding, listening, and reading comprehension. Multiple regression analysis showed that approximately 60% of the variance in reading comprehension of Spanish participants and 50% of the variance in reading comprehension of English participants were explained by decoding and listening comprehension. Furthermore, the performance of third grade Spanish participants resembled that of fourth grade English-speaking participants. In the second study, 102 Chinese students from Grade 2 and 106 students from Grade 4 were administered tasks of Chinese character recognition, reading fluency, listening, and reading comprehension. Multiple regression analyses showed character recognition and listening comprehension accounted for 25% and 42% of the variance in Chinese reading comprehension at Grades 2 and 4 respectively. These results indicate that the simple view of reading is applicable to writing systems other than that of English. 相似文献

Validation of an instrument for assessing teacher knowledge of basic language constructs of literacy
Recent national reports have stressed the importance of teacher knowledge in teaching reading. However, in the past, teachers' knowledge of language and literacy constructs has typically been assessed with instruments that are not fully tested for validity. In the present study, an instrument was developed; and its reliability, item difficulty, and item discrimination were computed and examined to identify model fit by applying exploratory factor analysis. Such analyses showed that the instrument demonstrated adequate estimates of reliability in assessing teachers' knowledge of language constructs. The implications for professional development of in-service teachers as well as preservice teacher education are also discussed. 相似文献

Same language subtitling (SLS) refers to the idea of subtitling motion media programmes (television and film) in the ‘same’ language as the audio. This simplest of additions in existing television programmes, especially film songs and music videos, can make a quantum contribution to the improvement of reading skills of over 325 million neo-literate people in India. Song videos are watched with great passion all over India, in every state and major language. Earlier work on SLS reported that it was found to enhance the entertainment value of televised songs for both literate and neo-literate viewers. This paper discusses a controlled experiment to ‘measure’ the impact of SLS on the reading skills of disadvantaged school children. The results confirm that SLS of film songs leads to reading skill improvement, thus reaffirming the enormous potential of this simple and economical approach for mass literacy skill development in India. 相似文献

AbstractPurpose: Developing countries need to plan growth or expansion of education so as to provide required trained manpower for different occupational sectors. The paper assesses supply and demand of professional manpower in Indian agriculture and the demands are translated in to educational requirements.Methodology: The supply is assessed from the output from agricultural education. The demand in various sub-sectors is assessed employing a mix of quantitative and qualitative forecasting tools. Based on the manpower gaps and extensive interactions with stakeholders, the manpower needs are translated into educational requirements.Findings: The demand–supply gap in agricultural professionals would cumulate to about 200,000 by 2020, which would need additional annual supply of 10,000 each of diploma holders and graduates.Practical implications: The study makes three main recommendations: first, to increase the supply of graduates and para-staff to cater to the emerging demand; second, agricultural education needs to meet the changing occupational structure; and third, responsibility for meeting agriculture education to be shared with the private sector.Originality/value: The paper proposes a mixed method that could be used to forecast human resource requirement in number of sub-sectors having differential information availability and growth patterns in terms of quality and quantity. Since the approach facilitates forecasting in situations of data limitations, it has potential for similar applications in many developing countries. 相似文献

Despite ample sunshine, 50–90% Indian children have Vitamin D deficiency (VDD). This enigma of widespread VDD needs exploration especially among under-fives as physiological variations in Vitamin D Binding Protein (VDBP) levels could be potential confounders in the interpretation of total 25-hydroxyvitamin D [25(OH)D]. However, there is scarce information about relevance of VDBP levels in under-five age group. We therefore, explored association of VDBP levels among 1–5 year old children with VDD. Serum levels of 25(OH)D, VDBP, calcium, parathyroid hormone (PTH) and alkaline phosphatase were estimated in 210 apparently healthy children in the age group of 1–5 years. VDD was defined as serum 25(OH)D levels < 20 ng/ml as per the IOM classification. VDBP levels were classified as low if levels were < 168 μg/ml as per the kit. The prevalence of VDD was 79.5% (n = 167) and VDBP levels were low in 48.6% (n = 102) of children. 25(OH)D levels correlated positively with VDBP (r = 0.298, p = 0.0001). A significant number of children (52.7%) with VDD had low VDBP (p = 0.015). and despite adequate sun exposure, 43% of children showed VDD and 56.6% had low VDPB levels. The low VDBP levels largely explain low 25OHD levels without necessarily implying VDD. It may add a new dimension for better understanding of widespread VDD among under-five children. It thus, points towards the need for redefining cut offs and complete evaluation of vitamin D status among under-fives including VDBP. 相似文献
