Level and Trend of Basic Education of Children in Bangladesh: 1993-1998     

Samir R. Nath  A. Mushtaque R. Chowdhury 《Educational studies》2002,28(1):77-92

Using data generated through two nationally representative sample surveys, this paper explores the trends in the level of basic education of Bangladeshi children. The instrument used for the purpose was based on the Declaration of the World Conference on Education for All (WCEFA, Jomtien, 1990). The findings reveal that the level of 'basic education' increased very slowly, 26.7% in 1993 to 29.6% in 1998, less than one percentage point per year. Statistically significant improvement was observed in 'life skills knowledge' and 'writing skills', but not in 'reading' or 'numeracy'. Girls progressed in 'reading', 'writing' and 'life skills', while the boys in 'writing' and 'life skills'. Over the period, the level improved for rural children but decreased for urban children. Bangladesh falls much behind the targets of the Jomtien Conference in 1990; it will have to wait until 2093 AD to reach the WCEFA goal. The country has made good progress in increasing the access to primary education, but a massive drive is necessary to improve the quality of education.  相似文献   

Effect of latent iron deficiency on GABA and glutamate neuroreceptors in rat brain     

Rama Devi Mittal  Amita Pandey  Balraj Mittal  Kailash Nath Agarwal 《Indian journal of clinical biochemistry : IJCB》2003,18(1):111-116

Eight weeks of latent iron deficiency in weaned female rats of Sprague Dawley strain maintained on experimental low-iron diet (18–20 mg/kg) did not significantly change the gross body, weight and tissue weights of brain and liver. Packed cell volume (PCV) and hemoglobin concentration remained unaltered. However, non-heme iron content in liver and brain decreased significantly (p<0.001). The activities of glutamate dehydrogenase, glutamic acid decarboxylase, and GABA-transaminase (GABA-T) in brain decreased by 15%, 11.4% and 25.7% respectively. However, this decrease was not statistically significant. Binding of³H Muscimol at pH 7.5 and 1 mg protein/assay increased by 143% (p<0.001) in synaptic vesicular membranes from iron-deficient rats as compared to the controls.³H glutamate binding to the synaptic vesicles was also carried out under similar condition. However, the L-glutamate binding was reduced by 63% in the vesicular membranes of iron deficient animals. These studies indicate that iron plays important functional role in both excitatory and inhibitory neurotransmitter receptors.  相似文献   

Sunyaev-zeldovich effect     

Biman Nath 《Resonance》2011,16(5):428-436

Soon after the discovery of the cosmic background radiation, Zeldovich and Sunyaev proposed that hot gas in galaxy clusters should cast a faint shadow because of the interaction between energetic electrons and the radiation photons. Sunayev-Zeldovich effect is now routinely observed, and it has become an important tool for studying the history of the universe.  相似文献

A descriptive model of innovation and creativity in organizations: a synthesis of research and practice     

Amar Dev?AmarEmail author  Januj A?Juneja 《知识管理研究与实践》2008,6(4):298-311

Based on a review of the reported theoretical advances that are affirmed by empirical works from published management practice, this paper finds that innovation is an outcome of an intentional and designed effort of the organization, and synthesizes the findings for enhancing creativity and innovation by developing three antecedents that positively influence innovation in organizations: (1) the garnered knowledge, (2) the presence of a knowledge-supporting culture, and (3) the accumulation of social capital. The paper also provides a summary of transferable management practices that organizations are employing to enhance innovation and productivity.  相似文献

Dark matter     

Bikram Phookun  Biman Nath 《Resonance》1999,4(10):40-46

In Part I¹ of this article we learnt that there are compelling evidences from dynamics of spiral galaxies, like our own, that there must be non-luminous matter in them. In this second part we will see that even clusters of galaxies must harbour dark matter. As if this was not enough, it turns out that if our knowledge of the universe is not completely wrong, then the universe as a whole has to contain dark matter and that it must be of some exotic type.  相似文献   

Dark matter     

Bikram Phookun  Biman Nath 《Resonance》1999,4(9):24-31

The study of gas clouds orbiting in the outer regions of spiral galaxies has revealed that their gravitational attraction is much larger than the stars alone can provide. Over the last twenty years, astronomers have been forced to postulate the presence of large quantities of ‘dark matter’ to explain their observations. They are still in the ‘dark’ as to its true nature.  相似文献
