Norman Borlaug and a hunger-free world     

M. S. Swaminathan 《Resonance》2014,19(2):109-115

Swami Vivekananda, whose 150th birth anniversary is being celebrated this year, used to say, “This life is short; its vanities are transient. He alone lives who lives for others”. Norman Borlaug was one such person, who lived and worked for the cause of ensuring food for all. As a scientist, he helped to breed outstanding varieties of dwarf wheat, which could help to triple the average yield. As a humanist, he placed faces before figures, and helped to highlight the fact that the persistence of hunger, in the midst of opportunities to increase food production through synergy between technology and public policy, is inexcusable. Dr Borlaug was not satisfied with scientific know-how alone. He wanted to convert scientific know-how into field level do — how. On the last day of his life, a scientist showed him a new equipment to trace soil fertility. Dr Borlaug’s last words before his death were, “Take the tracer to the farmer”. On the occasion of his birth centenary on March 25, 2014 we should all follow his advice and accelerate progress in linking the lab with land. His life and work will be eternal sources of inspiration and lead us to convert his vision of a hunger-free world into reality. Borlaug’s Approach to Increasing Wheat Yield  相似文献   

“It’s My Place”: Student Perspectives on Urban School Effectiveness     

Raji Swaminathan 《School Effectiveness & School Improvement》2013,24(1):33-63

This study investigated how graduates of an urban alternative school understood, interpreted, and compared their experiences in previous schools that they considered ineffective with their experiences at an effective alternative school. This study found that students find those schools effective that create or allow spaces where they can be empowered, leading to a sense of place. Students’ ownership or affinity to school spaces that lead them to refer to school as “my place” derived from school practices that were instrumental in promoting a sense of identification, commitment, integration, and alliances among students and faculty at the school. Based on the findings of the study, this article argues that for urban schools to be effective for students at risk, they not only need to focus on caring relationships and diverse learning experiences, they also need to create the space to foster a sense of “my place” for students.  相似文献   

Applications of the Hotelling T2 Statistic to Designs Involving Multiple Measures on Two Dimensions     

Hariharan Swaminathan  Linda L. Cook  Laurence Cadorette 《Journal of Experimental Education》2013,81(2):17-21

Multiple measures taken on subjects are usually classified along two dimensions: (1) measures on the same dependent variable taken at different periods of time or occasions; and (2) measures on different dependent variables taken at one testing or observation period. In this paper an appropriate procedure for the analysis of “multivariate repeated measures” designs, i.e. designs in which measures are taken along both dimensions simultaneously, is discussed. Examples are given of the application of the procedure to quasi-experimental time-series designs and to the problem of determining rater agreement when a group of individuals are rated on more than one variable.  相似文献   

Open learning in India: evolution,diversification and reaching out     

Ramesh C. Sharma 《Open Learning》2013,28(3):227-241

Distance education has a history of over four decades in India. There has been a vast growth in the number of learners who need education and thus also the corresponding channels of providing education. Due to the constraints of the traditional educational sector, open and distance learning has been found to be a workable alternative strategy in India. This paper traces the evolution and diversification of open learning in India by examining various factors that led to the growth and success of open learning. This system, as other systems of education, is not free from problems and a critique is provided on the various factors affecting the smooth functioning of India’s open and distance learning system.  相似文献

When can one call a sequence of heads and tails truly random? This article is about the Kolmogorov or algorithmic complexity of a sequence. This complexity tells you how random a sequence is.  相似文献   

Rethinking the Indian Digital Divide: The Present State of Digitization in Indian Management Libraries     

Ramesh C. Gaur 《International Information and Library Review》2003,35(2-4):189

In this paper efforts have been made to analyze the present status of digitization of Indian Management Libraries through a survey carried out in 500 management libraries in India. The issues such as library automation, development of digital libraries, and use of bar code and smart card technology have been discussed. Issues responsible for the widening of the digital divide have been identified.  相似文献   

Investigating geographic variation in use of psychotropic medications among youth in child welfare     

Leslie LK  Raghavan R  Hurley M  Zhang J  Landsverk J  Aarons G 《Child abuse & neglect》2011,35(5):333-342

Objectives

Public Law (P.L.) 110-351, the “Fostering Connections to Success Act,” calls for state child welfare agencies to partner with Medicaid and pediatric experts to provide planning and oversight regarding the provision of health and mental health services, including medication, to children in state custody. Recent reports, media cases, and class action lawsuits suggest over-use of psychotropic medications to address the behavioral needs of children in the child welfare system. We examined geographic variability in psychotropic medication use across US child welfare agency catchment areas to determine how rates of psychotropic medication use vary in relation to child, community, child welfare, and health system-level factors.

Methods

Cross-sectional analysis of Wave 1 data for the 92 child welfare catchment areas participating in the National Survey of Child and Adolescent Well-being, a random probability sample of 2,504 children ages 2-15 years undergoing investigation for abuse and neglect. We employed multilevel regression modeling to examine the impact of catchment-level variables on medication use, controlling for child-level variables.

Results

Fifteen percent of children reported taking psychotropic medications. Rates of medication use across catchment areas ranged widely from 0 to 40%, a 40-fold difference. On multi-level logistic regression modeling, older age (p < .001), male gender (p < .001), emotional and behavioral problems (p < .001), and insurance (p = .05) were associated with psychotropic medication use at the child-level. At the catchment-level, stressful environment within the child welfare system was negatively associated with medication use. No other catchment-level variables examined were found to explain use.

Conclusions

Striking disparities in medication use exist across catchment areas in this national sample. Of the catchment variables examined, only stressful environment was related to medication use.

Practice implications

These findings highlight significant geographic variation in medication use that most likely reflect both under-use and over-reliance on psychotropic medication. The link between child welfare environment and medication use suggests the influence of systemic, as opposed to clinical, causes of variation in medication use. This requires greater implementation of organizational processes governing quality of care for this highly vulnerable population.  相似文献   

Antidyslipidemic Effect of Ocimum sanctum Leaf Extract in Streptozotocin Induced Diabetic Rats     

Ishrat Husain  Ramesh Chander  Jitendra Kumar Saxena  Abbas Ali Mahdi  Farzana Mahdi 《Indian journal of clinical biochemistry : IJCB》2015,30(1):72-77

The antidyslipidemic activity of Ocimum sanctum leaf extract was studied in streptozotocin induced diabetic rats. In this model, there was significant increase in plasma markers of diabetic-dyslipidemia following diminution of lipid metabolizing enzymes. Oral administration of leaf extract (500 mg/kg b.w.p.o.) for 15 days resulted in significant decrease in diabetogenic and dyslipidemia parameters; namely blood glucose, glycosylated hemoglobin, lipid peroxide, free fatty acids, small dense low density lipoprotein, lipid and protein components of plasma lipoproteins, adipose and liver. The regulation of lipids was accompanied by stimulation of postheparin lipolytic activity, reactivation of lecithin cholesterol acyl transferase and hepatic lipoprotein lipase enzymes. The results of the present study demonstrated antidyslipidemic and antioxidant activities in leaf extract of O. sanctum which could be used in prevention of diabetic-dyslipidemia and related complications.  相似文献   

Evaluation of genetic potential of the polyvoltine silkworm （Bombyx mori L.） germplasm and identification of parents for breeding programme     

Rao CG  Seshagiri SV  Ramesh C  Ibrahim Basha K  Nagaraju H  Chandrashekaraiah 《Journal of Zhejiang University. Science. B》2006,7(3):215-220

In the present study, polyvoltine germplasm stock ofAndhra Pradesh State Sericulture Research and Development, Institute （APSSRDI） was evaluated for its performance based on quantitative and qualitative traits. Twenty-one oval and 10 peanut cocoon shaped lines were reared in different seasons of the year. Since the polyvoltines are non-diapausing, six generations were reared and evaluated for various economically important traits based on evaluation index and sub-ordinate function statistical methods. Ten top ranked lines obtained by using both the methods were identified as potential parental strains. Among oval lines, APMI4, APMI 1, APMIS, APMW9, and APMI9, and among peanut lines APMD5, APMDI, APMD3, APMD9 and APMD8 were selected as base material. The identified high yielding lines will be used in various breeding programmes as initial parents for the synthesis of superior polyvoltine breeds/hybrids.  相似文献
