采用Eberhart和RusseⅡ(1966)的分析模式评价了12个夏芝麻品种(系)产量等10个性状的稳定性,并按Spearman等级相关的方法研究了产量稳定性与其他性状稳定性间的相关关系.结果表明,大多数品种(系)产量等10个性状的平均表现与环境指数呈显著或极显著的线性关系;产量的稳定性与单株蒴数、单株粒重及株高的稳定性呈显著或极显著正相关.因此,单株蒴数、单株粒重和株高的稳定性可作为夏芝麻稳产性育种的间接依据. 相似文献

With the increasing occurrence of haze during the summer, the physicochemical characteristics and toxicity differences in PM2.5 in different seasons are of great concern. Hangzhou is located in an area that has a subtropical monsoon climate where the humidity is very high during both the summer and winter. However, there are limited studies on the seasonal differences in PM2.5 in these weather conditions. In this test, PM2.5 samples were collected in the winter and summer, the morphology and chemical composition of PM2.5 were analyzed, the toxicity of PM2.5 to human bronchial cells BEAS-2B was compared, and the correlation between PM2.5 toxicity and the chemical composition was discussed. The results showed that during both the winter and summer, the main compounds in the PM2.5 samples were water-soluble ions, particularly SO42?, NO3?, and NH4+, followed by organic components, while heavy metals were present at lower levels. The higher the mass concentration of PM2.5, the greater its impact on cell viability and ROS levels. However, when the mass concentration of PM2.5 was similar, the water extraction from the summer samples showed a greater impact on BEAS-2B than that from the winter samples. The cytotoxicity of PM2.5 was closely associated with heavy metals and organic pollutants but less related to water-soluble ions. 相似文献

AbstractThis article looks at the French state’s approach to the “colonies de vacances” between 1944 and 1958. Created in 1876 by the Reverend Bion in Zurich, these summer camps originated as a charitable institution: their initial purpose was to provide rural retreats and to restore the health of poor urban youth. Set up on French soil in 1880, these institutions gradually grew in France in the late nineteenth and early twentieth centuries. Considered both as complements to the republican school and as extensions of the “patronages” (parish unions), they were important for children and adolescents from the industrial city suburbs, and were enshrined in the leisure policies of the Popular Front from 1936 onwards. After the Second World War, summer camps in France became a major social institution (300,000 children went to summer camps in 1945, 900,000 in 1949) in response to both hygiene and educational needs. Based on the archives of the Directorate of Youth Movements and Popular Education (1944–1947) and the General Directorate of Youth and Sports (1948–1958), this article aims to examine the politics behind the organisation of these summer camps and to demonstrate the social and political importance of these popular educational institutions which, in 1957, involved 1.35 million French children and teenagers. Although the history of French summer camp federations (UFCV, CEMEA, CPVC, UFOVAL, etc.) has been widely studied, how the state sees its role and influences these organisations has mostly been considered indirectly. The intention is to show that among the educational, cultural and sports policies implemented during the Fourth Republic in France, those related to the organisation of “colonies de vacances”, and therefore the organisation of holidays for a very large number of children and teenagers, occupy a significant place. In 1944, the summer camps were widely supported by the French state, which also planned to regulate this booming sector. The creation of qualifications for summer camp staff and directors in 1949 obliged organisations to start training schemes: they trained staff and directors to work in the municipal camps, associations, etc. Security issues led to the state tightening control of the summer camps, their recruitment and their activities. There was a great deal of political investment in these “colonies de vacances” during this period, and this was reflected in the creation of a Ministerial Education Committee in 1950, a general and regional body of inspectors for these camps, etc. However, the considerable expansion of summer camps posed increasing problems at the national political level resulting in changes to the initial subsidy policies. The State played a major part in crucial issues such as the sociological diversification of these institutions and the changes in their social role according to evolving sociocultural trend. The fact remains that the “colonies de vacances” were for the French state a centrepiece of the “popular education” that the political actors of the Fourth Republic wanted to implement in order to build the France of the post-war period.. 相似文献

This field-based randomized trial examined the effect of assignment to and participation in summer school for two moderately at-risk samples of struggling readers. Application of multiple regression models to difference scores capturing the change in summer reading fluency revealed that kindergarten students randomly assigned to summer school outperformed their control group peers by .60 of a standard deviation in an intent-to-treat analysis. For the first grade sample, the intent-to-treat estimate was over three quarters of a standard deviation. The contrast in performance was greater when the comparison was focused more specifically on the change in literacy between treatment participants (i.e., randomly assigned students who actually attended summer school) and students randomly assigned to the control group and in analyses that explicitly adjusted for non-compliance with treatment assignment. These results support the experiential intuition of school district personnel regarding the benefits of summer school and suggest that targeted summer instruction can be a useful strategy to support student learning over the summer months. 相似文献
