Quantitative trait loci (QTL) analysis was conducted in bread wheat for 14 important traits utilizing data from four different mapping populations involving different approaches of QTL analysis. Analysis for grain protein content (GPC) sug- gested that the major part of genetic variation for this trait is due to environmental interactions. In contrast, pre-harvest sprouting tolerance (PHST) was controlled mainly by main effect QTL (M-QTL) with very little genetic variation due to environmental interactions; a major QTL for PHST was detected on chromosome arm 3AL. For grain weight, one QTL each was detected on chromosome arms 1AS, 2BS and 7AS. QTL for 4 growth related traits taken together detected by different methods ranged from 37 to 40; nine QTL that were detected by single-locus as well as two-locus analyses were all M-QTL. Similarly, single-locus and two-locus QTL analyses for seven yield and yield contributing traits in two populations respectively allowed detection of 25 and 50 QTL by composite interval mapping (CIM), 16 and 25 QTL by multiple-trait composite interval mapping (MCIM) and 38 and 37 QTL by two-locus analyses. These studies should prove useful in QTL cloning and wheat improvement through marker aided selection. 相似文献

The increase in smartphone adoption has been no less than astounding. Unfortunately, the explosive growth has been accompanied by a rash of security problems. A contributing factor to the growing security problem is a lack of education, training, and awareness. In addition, “bring your own device” (BYOD) policies often leave security responsibilities to the competencies of device owners, which compromises security. Today’s students are tomorrow’s employees with responsibilities for protecting their work environment. They need to understand and practice a full-range of mobile security practices so that they can safely access the information assets of their organizations. If students are not engaging in such practices, educational institutions have a responsibility to ensure that students understand how to keep information assets secure. This paper investigates the smartphone security practices of undergraduate college students. Five hundred students in business classes at a regional public university were surveyed to determine their use of recommended smartphone security practices. The study found that many smartphone users did employ some security measures, but a high percentage of them were ignoring potential risks. This suggests a need for increased education, training, and awareness. 相似文献

Household engagement in a child??s education is a complex process; depending on the culture and the context, it may be revealed through a variety of behaviours. Using data from one district in rural Gujarat, India, four indicators of a household??s educational engagement were employed to investigate the relationship between household literacy levels and the household??s engagement in the education of its child members. The findings on educational engagement were also compared across households with different wealth and income levels. Uniformly, indicators of household literacy levels were found to be more important in understanding a household??s educational engagement than a household??s wealth and income levels. 相似文献

This paper contributes to the important but small body of research on the role of private schools in Indian education. It uses a household dataset from India with a rich set of household covariates and student performance data on reading, writing, and mathematics. For both rural and urban India the results from regression analyses indicate that private school students perform better on tests controlling for covariates. In both contexts, however, the private school benefit becomes largely, statistically, insignificant after conducting multivariate analysis on data balanced using the propensity score matching technique. The paper also makes an initial attempt to identify ‘low-fee’ private schools; within the regression framework it finds that children in such schools may perform no better than their public school counterparts. The data and methods used in this paper are not without limitations; however these analyses call into question the claim that private school effect may be unequivocally positive and highlights the potential heterogeneity in private school performance in the Indian context. 相似文献

A brief history of the development of Early Childhood Care and Education in pre and post Independent India has been given first. The current situation of ECCE, teacher training and research has been described and the Research — Policy — Program interface has been delineated.
Among the myriad issues confronting ECCE in the country a few have been selected for discussion. 相似文献

This longitudinal study investigated associations between children's learning-related behaviors and literacy achievement in an ethnically diverse sample of low-income children throughout elementary school. Children's literacy and learning-related behavior (e.g., working independently, seeking challenges) were assessed when they were in kindergarten or first grade and again in the third and fifth grades. The results showed fair consistency over time in both learning-related behaviors and literacy skills. Learning-related behaviors in one grade predicted literacy achievement in the subsequent grade in which it was assessed, but literacy skills did not predict subsequent learning-related behaviors. 相似文献

There are thousands of children who remain out of school at both primary and secondary levels in Turkey. The current disparities in access to education in Turkey are mostly driven by systematic regional differences and high gender inequalities. Although several existing studies have paid close attention to gender-based inequities in school access, none of the existing studies have attempted to systematically understand regional differences in schooling. This study therefore intends to address this gap in the literature. Results of the study indicated several key factors, such as gender, household poverty and gender role attitudes, that contributes to the regional inequalities in access to education in Turkey. Based on these findings, suggestions for policy makers and future research were made. 相似文献
