The attitudes of Hong Kong primary school principals toward integrated education

Umesh Sharma 서울대학교 교육연구소 2008 Asia Pacific Education Review Vol.9 No.3

Positive attitudes of key stakeholders, such as school principals, towards a new policy are considered a necessary pre-requisite to implement any such policy. Hong Kong has recently formulated a policy that supports the integration of students with disabilities into regular schools. This Study investigated the attitudes of Hong Kong primary school principals toward integration, with a view to determining if these school leaders are prepared to implement integrated education practices in their schools. A modified version of the School Principals' Attitudes toward Inclusion scale (Bailey, 2004) was used to collect data from participants. Based on the responses of 130 primary school principals. it was found that their attitude,.; toward integration were slightly negative. Principals who had less teaching experience and who were administering schools with smaller student enrolment were found to hold more positive attitudes toward integration. The variable of "having a family member or close friend with a disability" had a significant and positive effect on the principals' attitudes toward integration.

What concerns pre-service teachers about inclusive education: An international viewpoint?

Umesh Sharma,Chris Forlin,Tim Loreman 한국교육개발원 2007 KEDI Journal of Educational Policy Vol.4 No.2

This study examined concerns of 603 pre-service teachers regarding the inclusion of students with disabilities into regular schools prior to teachers obtaining training in special education. The sample of the study was selected from tertiary institutions located in Australia, Canada, Hong Kong, and Singapore. It was found that participants from Hong Kong and Singapore were significantly more concerned than participants from Australia and Canada. Three variables: confidence in teaching students with disabilities, knowledge of local disability policies or acts, and contact with persons with disabilities were found to be related significantly to their overall concern levels. The results of the study are discussed with possible implications for teacher educators.

Classical and Bayesian methods of estimation for power Lindley distribution with application to waiting time data

Sharma, Vikas Kumar,Singh, Sanjay Kumar,Singh, Umesh The Korean Statistical Society 2017 Communications for statistical applications and me Vol.24 No.3

The power Lindley distribution with some of its properties is considered in this article. Maximum likelihood, least squares, maximum product spacings, and Bayes estimators are proposed to estimate all the unknown parameters of the power Lindley distribution. Lindley's approximation and Markov chain Monte Carlo techniques are utilized for Bayesian calculations since posterior distribution cannot be reduced to standard distribution. The performances of the proposed estimators are compared based on simulated samples. The waiting times of research articles to be accepted in statistical journals are fitted to the power Lindley distribution with other competing distributions. Chi-square statistic, Kolmogorov-Smirnov statistic, Akaike information criterion and Bayesian information criterion are used to access goodness-of-fit. It was found that the power Lindley distribution gives a better fit for the data than other distributions.

Early Cretaceous subvolcanic calc-alkaline granitoid magmatism in the Nubra-Shyok valley of the Shyok Suture Zone, Ladakh Himalaya, India: Evidence from geochemistry and U–Pb SHRIMP zircon geochronology

Kumar, Santosh,Bora, Sita,Sharma, Umesh K.,Yi, Keewook,Kim, Namhoon Elsevier 2017 Lithos Vol.277 No.-

<P><B>Abstract</B></P> <P>The lithounits constituting the Ladakh Himalaya are exposed along the Indus and Shyok Sutures Zones of northwest Himalaya. The Shyok Suture Zone (SSZ) in northern Ladakh represents a highly tectonized zone of a back-arc basin, which is mainly composed of volcano-sedimentary formations (Shyok and Khardung Formations) intimately, associated with intrusive granitoids. In the Nubra-Shyok valley of the SSZ calc-alkaline granitoids of batholithic dimension are exposed in the Tirit region, referred herein as the Tirit granitoids, which are intrusive evidently into the Shyok volcanic (rhyolite) rocks belonging to the Shyok Formation. In this valley the northern margins of granitoids of the Ladakh batholith can also be found intrusive into the metasediments (shale/slate) and metavolcanics of the Shyok Formation. The compositions and crystallization pressures (~66 to 91MPa) of amphiboles in the intrusive Tirit granitoid corroborate a calc-alkaline nature and solidification of Tirit granitoid melt at subvolcanic level equivalent to a minimum of 2.5km to a maximum of 3.5km thick overburden of Shyok volcanics. U–Pb SHRIMP zircons from the Tirit granitoids have yielded mean crystallization ages of 109.4±1.1Ma and 105.30±0.80Ma, which strengthen the idea of Early Cretaceous subduction beneath the Karakoram terrain. Inherited older zircon cores (278–393Ma, 476–519–713–952Ma and 1933Ma) suggest a contribution from heterogeneous Palaeozoic and Proterozoic sources in the generation of the Tirit granitoids similar to those observed elsewhere in the Karakoram-Kohistan region. A mean crystallization age (105.30±0.80) of zircons in the Tirit granitoid hosting xenoliths of porphyritic volcanics places a minimum eruption age of ca. 105Ma for the Shyok volcanics. The Ladakh granitoid, Tirit granitoids and porphyritic volcanic xenolith belong to a calc-alkaline series. A mean crystallization age (67.32±0.66Ma) for zircon in the Ladakh granitoid implies that the Shyok metasediments (shale/slate) were deposited and metamorphosed prior to ca. 68Ma. Present and earlier determined ages on Tirit granitoids revealed that the subduction-related calc-alkaline magmatism in the Nubra-Shyok valley of the SSZ prevailed between 110 and 68Ma, and hence a minimum age of Early Cretaceous can be suggested for development of the SSZ.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Field and geobarometric (~56 to 129MPa) evidence corroborates solidification of Tirit granitoid melt at subvolcanic level. </LI> <LI> Ages (109.4±1.1, 105.3±0.8Ma) and calc-alkaline nature of Tirit granitoids record Early Cretaceous (>110Ma) subduction. </LI> <LI> A minimum age of Albian for Shyok volcanics and Maastrichtian for Shyok metasediments is suggested. </LI> <LI> Palaeozoic to Proterozoic inherited zircons imply role of heterogeneous sources in the formation of Tirit granitoid melts. </LI> </UL> </P>

Bhatt, R.S.,Sharma, S.R.,Singh, Umesh,Kumar, Davendra,Bhasin, V. Asian Australasian Association of Animal Productio 2002 Animal Bioscience Vol.15 No.6

An experiment was conducted on 190 progeny (winter -74; summer -59; rainy -57) of 12 Grey Giant rabbits (10 female +2 males), to assess the effect of different seasons in a year, on their reproductive, growth and productive performances along with feed efficiency, under sub-temperate Himalayan conditions. The daily meteorological attributes recorded during winter (October to March), summer (April to June) and rainy (July to September) seasons, and analysed were minimum and maximum temperature, relative humidity and rainfall. Various biological parameters recorded were doe weights at mating and kindling, litter size at birth, litter weight at birth, kit mortality, litter size at weaning, litter weight at weaning, weekly body weight up to 98 d and weaner mortality. Individual weight gains, dressing percentages, meat weights, liver weights, raw-pelt weights, processed pelt weights and processed pelt areas at slaughter on d 84 and 98, respectively were also recorded. The feed and fodder compositions and their nutritive values during different seasons were also analysed. Average ambient temperature during winter, summer and rainy seasons were $13.2{\pm}2.8$, $22.4{\pm}3.7$ and $24.8{\pm}2.3^{\circ}C$, respectively. The average relative humidity and total rainfall for winter, summer and rainy seasons were $68.9{\pm}1.5$% and $48{\pm}26.6$mm, $66.3{\pm}4.8$% and $125.6{\pm}56.8$ mm, and $77.3{\pm}1.3$% and $116.3{\pm}90.4$ mm, respectively. The weight of doe at mating and kindling, litter size at birth, litter weight at birth and litter size at weaning were comparatively higher whereas litter weight at weaning was significantly (p<0.05) higher during winter as compared to summer and rainy seasons. The kit mortality was significantly (p<0.05) higher during winter while the weaner mortality was significantly (p<0.05) higher during rainy season. At 84 d, the live weight per doe, slaughter weight, dressing percentage and liver weight were significantly (p<0.05) higher during winter than summer and rainy. Similarly, the gain in weight and meat weight at 84 and 98 d were significantly (p<0.05) higher during winter. The weight of raw pelt and processed pelt were recorded significantly (p<0.05) higher during winter while no difference in the area of processed pelts during different seasons could be observed. No difference in the biological performance could be observed between sexes in any of the seasons. Roughage analysis revealed comparatively higher crude protein percent and lower crude fibre percent during summer and rainy seasons than in winter. The roughage dry matter intake was comparatively higher during summer and rainy seasons vis-a-vis constant amount of concentrate supplied during all the three seasons. The digestibilities of dry matter was significantly (p<0.05) lower, whereas that of crude fiber, acid detergent fibre and cellulose were negative during winter. Interestingly, the feed:gain was exceedingly well during winter than in other seasons and it is concluded that it was the best season for production of rabbits under sub-temperate Himalayan conditions.

Design, Synthesis and Biological Evaluation of Some Novel Benzimidazole Derivatives for Their Potential Anticonvulsant Activity

Priyal Jain,Prakash Kumar Sharma,Rajesh Singh Pawar,Umesh Kumar Patil,Pradeep Kumar Singour,Harish Rajak 대한약학회 2010 Archives of Pharmacal Research Vol.33 No.7

Selective GABAA receptor ligands are widely used clinically to reduce the occurrence of convulsions. Hence there is an intense interest in developing new benzimidazole derivatives demonstrating high selectivity and high affinity for GABAA receptors. With the purpose of designing new chemical entities with an enhanced binding affinity for GABAA/BZd receptor complex, we carried out a QSAR study on benzotriazine derivatives. We studied 28 potent GABAA receptor ligands; derivatives of benzotriazines, using a combination of various tested physicochemical, steric, electronic and thermodynamic descriptors to determine the quantitative correlation between binding affinity and structural features. The developed and validated final model showed a good correlative and predictive ability expressed by a squared correlation co-efficient (r2) of 0.954. The equation indicated that the binding affinity is strongly dependent upon the thermodynamic properties (CDE, DDE and PC). Correlation between these properties and anticonvulsant activity was used to synthesize compounds possessing potent anticonvulsant activity. Most of the compounds showed an ability to inhibit the maximum electroshock (MES) and pentylenetetrazole (PTZ)-induced convulsions. Compound 1A, i.e. 2-(4-Chloro-phenyl)-5-nitro-1H-benzimidazole exhibited maximum activity in both the convulsion models.

Cavitation resistance of concrete containing different material properties

Kumar, G.B. Ramesh,Bhardwaj, Arjit,Sharma, Umesh Kumar Techno-Press 2018 Advances in concrete construction Vol.6 No.1

In the present investigation, influence of various material parameters on the cavitation erosion resistance of concrete was investigated on the basis of laboratory experiments. As there is no well-established laboratory test method for evaluating the cavitation resistance of concrete, a test set up called 'cavitation jet' was specially established in the present study in order to simulate the cavitation phenomenon experienced in the hydraulic structures. Various mixtures of concrete were designed by varying the grade of concrete, type and quantity of pozzolana, type of aggregates and cement type to develop good cavitation resistant concrete constructed using marginal aggregates. Three types of aggregates having three different Los Angeles abrasion values (less than 30%, between 30% and 50% and more than 50%) were employed in this study. To evaluate the cavitation resistance a total of 60 cylindrical specimens and 60 companion cubes were tested in the laboratory respectively. The results indicate that cavitation resistance of concrete degrades significantly as the L.A. abrasion value of aggregates goes beyond the 30% value. Incorporation of pozzolanic admixtures was seemed to be beneficial to enhance the cavitation resistance of concrete. Influence of other material parameters on the cavitation resistance of concrete was also noted and important observations have been made in the paper.
