SPECIAL EDUCATION in Bangladesh reflects the overall educational problems faced by the nation. While some government programs for children with sensory disabilities are provided, most special education is supported by non‐government organizations. Though planning for improved special education has occurred, implementation has been restricted by economic constraints. 相似文献

A randomized evaluation of a 9-month comprehensive math program for preprimary Bangladeshi school children addressed skills such as numbers, measurement, shapes, patterns, and space. Nine schools were randomly selected for the Intervention group and nine for the Control group, with 12 children randomly selected from each to participate in testing. Pre- and posttested scores on each unit's skills and a cumulative test at the end were subjected to analyses of covariance. Intervention children doubled their scores on almost all tests while control children increased only slightly. Reasons for the program's effectiveness were discussed. 相似文献

In wind power system, low frequency oscillations are observed due to imbalance between mechanical input and electrical output. Hence, variable susceptance controllers are being adopted to mitigate these oscillations. However, improper modulation of control parameters also leads to system instability. Therefore, we propose an optimization methodology for mitigating low frequency oscillations in wind power generation system. To visualize our methodology, we use a lead-lag type variable susceptance controller for fixed speed induction generator (FSIG) based wind generation system. Then, we optimize gain and time constants of lead-lag controller using three optimization algorithms: particle swarm optimization (PSO), genetic algorithm (GA), and flower pollination algorithm (FPA). Later, we perform non-linear time domain simulation and quantitative analysis to find average fitness, standard deviation, run time, and iteration number for these optimization algorithms. Moreover, non-parametric statistical analysis, such as Kolmogorov–Smirnov and Wilcoxon signed-rank tests are employed for identifying statistically significant differences among these algorithms. 相似文献

This essay review discusses the report of TheTask Force on Higher Education and Society(TFHES), convened in 1998 by the World Bank butindependently financed and staffed incollaboration with UNESCO and severalfoundations. Peril and Promise marks anhistoric turning point in the framework forpostsecondary educational planning. Rate-of-return analysis has been de-emphasized,while promotion of the public interest hasmoved front and center. The report of theTFHES, published in 2000 by the World Bank, hasreceived deserved attention in some parts ofthe world and has even developed an associatedwebsite (http://www.tfhe.net). As we explainbelow, the framework advocated by the TFHES isalready being used in official policy documentsof the World Bank, whose position will surelymultiply the influence of the Task Forcethrough its effect on other development banksas well as on programs of bilateral nationalassistance. And yet, despite its seminalimportance, the TFHES report has yet to befully appreciated by many researchers of highereducation. With this essay review, we hope tobroaden the discussion of the Task Force, and to offer a preliminary assessment of its impactin the 2002 World Bank policy document, and toconnect its arguments to questions that arecentral in the scholarly literature of ourfield. 相似文献

This paper describes the ways used to build digital libraries in Bangladesh as well as the problems that might be encountered during digital library system development. It shows the existing status of digital library development, particularly the status of digitization in Bangladesh as well as government initiatives to build digital library system. Finally, several steps are proposed by the author for one possible approach to build an effective digital library system. 相似文献

Our study examines the environmental knowledge (EK) and behavioural outcomes of students studying ecotourism in Sydney, Australia. Three competing models were tested to examine the relationships between EK, participation intention (PI) in ecotourism programs, landscape likeability (LL) and social interactions (SI); and the study also tested the moderated mediation influence of gender differences and relationship length on mediators. Partial least squares-based structural equation modelling (PLS-SEM) was used to analyse the data collected from 173 residential tourism students. Key findings suggest whilst LL and PI are significant outcomes of EK, LL has a stronger mediating effect on PI compared to SI; and all mediation effects are further moderated by gender differences. However, only Model 3 confirms the moderating effect of the length of relationship. Noting the key role that EK plays in influencing their PI and LL, our study also suggests ways of developing the tourism students’ EK, through various experiential and pedagogical interventions. 相似文献

Objective
Scandix pecten-veneris L. is a less studied wild edible herb and is considered an extinct plant species in many parts of the world. This study was designed to evaluate its phytochemical composition and biological potential of S. pecten-veneris L.Methods
Phytochemicals including alkaloids, flavonoids, polyphenols, and tannins were determined in extracts of S. pecten-veneris. Antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), while reducing power was tested by ferric reducing/antioxidant power (FRAP) assay. Antimicrobial activity against seven bacterial and four fungal strains was evaluated using agar well diffusion assay. Enzymes inhibition study was performed for urease, phosphodiesterase-I, and catalase-II.Results
S. pecten-veneris showed moderate antiradical activity and reducing potential of hydroxyl radicals to about 20% of the initial value. The antioxidant activity of various extracts of S. pecten-veneris showed a linear correlation with total phenolic contents in the order of water>n-butanol>chloroform>ethyl acetate>methanol extracts. S. pecten-veneris leaves showed the highest inhibitory activity against Staphylococcus aureus while the highest antifungal activity was observed against Candida albicans. The plant extract was most potent against urease enzymes but showed moderate activity against phosphodiestrase-I and carbonic anhydrase-II.Conclusions
Our data demonstrate that in addition to its culinary uses, S. pecten-veneris has good medicinal potential and hence could be used for treating some specific health ailments.10.

Technologies are increasingly adopted and used by young children at home. Parents play an important role in shaping their media use, keeping certain possibilities open for children to play, learn, and socialize while limiting others. Nevertheless, the literature on parental mediation of young children’s media use is scant. In this article, we describe a qualitative, mixed-method study involving 24 parents and 36 children aged 3 to 9, and focus on the contextual factors that shape (transitions between) parental mediation practices. The results point to the emergence of new manifestations of parental mediation and provide evidence of their dynamic, often paradoxical nature. In particular, the insights on distant mediation, various buddy styles, and participatory learning, as well as the value of a wholeness approach for understanding children’s conditions for media engagement, suggest new prospects for parental mediation literature. 相似文献
