体育文化素养与大学生可持续发展研究

大学生可持续发展,是指大学生在大学阶段及其以后的职业生涯中连续不断地发展和完善的过程。大学生可持续发展能力是大学生保持自身可持续发展态势,并具有持续不断地获取、运用和创新知识的能力。体育文化素养是大学生必须具备的身心素养和体育知识素养,是大学生实现可持续发展重要的身体与文化基础。通过更加科学、合理、有效的大学体育教育教学途径,真正实现体育文化素养与大学生可持续发展的有机结合。     

重金属对香蕉生长影响的试验研究

对香蕉园土壤与灌溉水添加Cd、Hg、As、Pb、cr、cu重金属元素,研究该重金元素对香蕉生长影响,以及香蕉叶片对该重金元素的富集能力。结果表明：当重金属的浓度累集到一定值时,会对香蕉的生长发育产生抑制作用,浓度太高会造成香蕉的生长停滞甚至死亡。随着土壤中Pb、Cd、As、Hg、cr、Cu重金属含量的增加,香蕉叶片中富集的重金属含量和富集系数表现为正相关的递增,香蕉叶片富集系数为Cr〉Cd〉Hg〉As〉Cu〉Pb,重金属的添加量与香蕉叶片体内含量的相关系数（r）分别为0．9630～0．9994、0．9128～0．9983。     

草、品种鸡蛋蛋黄营养成分分析

本文对草、品种鸡蛋蛋黄进行感官评定和部分营养指标理化分析。实验结果表明 :草鸡蛋和品种鸡蛋蛋黄的感观综合评分分别为 84.5和 6 8.0 ;草鸡蛋和品种鸡蛋的蛋黄色泽指数分别为 1 0 .0和 2 .5 ;草鸡蛋蛋黄中水分和胆固醇含量低于品种鸡蛋 ,而草鸡蛋蛋黄中粗脂肪、磷脂质含量显著高于品种鸡蛋 ,二者蛋白含量无明显差异。     

Studies on nutrient uptake of rice and characteristics of soil microorganisms in a long-term fertilization experiments for irrigated rice

The ecosystem characteristics of soil microorganism and the nutrient uptake of irrigated rice were investigated in a split-block experiment with different fertilization treatments, including control (no fertilizer application), PK, NK, NP, NPK fertilization, in the main block, and conventional rice and hybrid rice comparison, in the sub block. Average data of five treatments in five years indicated that the indigenous N supply (INS) capacity     

Arts enrichment and preschool emotions for low-income children at risk

No studies to date examine the impact of arts-integrated preschool programming on the emotional functioning of low-income children at risk for school problems. The present study examines observed emotion expression and teacher-rated emotion regulation for low-income children attending Settlement Music School's Kaleidoscope Preschool Arts Enrichment Program. At a level of p < .001, results indicate the following. First, within Kaleidoscope, children showed greater observed positive emotions such as interest, happiness, and pride, in music, dance, and visual arts classes, as compared to traditional early learning classes. Second, children at Kaleidoscope showed greater observed positive emotions than peers attending a comparison preschool that did not include full integration of the arts. Third, across the school year, children at Kaleidoscope showed greater growth in teacher-rated levels of positive and negative emotion regulation. The implication is that arts enrichment may promote social–emotional readiness to learn for low-income children at risk for school problems.     

“三个代表”与列宁主义的党建思想比较研究论纲

江泽民“三个代表”思想的提出与列宁主义党建思想的产生有着相似的历史背景;“三个代表”思想实践并丰富了列宁主义的党建思想;“三个代表”思想同列宁主义的党建思想一样,各自在不同的历史时期起到了历史性的伟大作用。     

构建社会主义和谐社会:马克思主义的重要丰富和发展

提出构建社会主义和谐社会新论断,是中国共产党人的重大理论创新。这一论断的提出顺应了全面建设小康社会实践的要求,符合马克思主义关于社会主义社会的科学构想,为中国特色社会主义理论增加了崭新内容,是对马克思主义的重要丰富和发展。深刻认识这一论断的马克思主义理论品质,具有重要的现实意义。     

Analysing attempts to support outdoor learning in Scottish schools

The new ‘Curriculum for Excellence’ in Scotland outlines a policy vision of a more integrated and holistic form of education; a commitment which offers considerable prospects for increased levels of outdoor learning in schools. With reference to Fullan’s theorizing on achieving educational change, this study investigated four main implementation areas, namely: policy aims, partnerships arrangements, and associated professionalism and sustainability issues. Evidence was collected through a series of 16 semi-structured interviews with key stakeholders at national, local authority, and school level. Despite increased agreement on aims, it was found that improving the frequency and quality of outdoor learning in schools was adversely influenced by the patchwork nature of partnership support at national and local authority levels. This has curtailed the prioritizing of outdoor learning in schools and of teachers being supported when trying to make use of their increased curriculum decision-making responsibilities. Thus, only limited evidence was found of policy-related innovation and considerable evidence of policy stasis. As such, building national capacity is proving difficult. It is concluded that further research on how some atypical schools have managed to develop their programmes offers the best prospects for understanding the complexities of achieving greater levels of outdoor learning.     

养分胁迫下的夏玉米生理反应与光谱特征

在夏玉米整个生育期的不同阶段，测定其叶片光谱反射率，并结合其生物物理参数的变化进行分析。结果表明，叶绿素浓度、叶面积指数等生物物理参数，可以反映作物生长发育的特征动态，也是反映物质生产和反射光谱关系的中间枢纽，通过叶绿素浓度含量与叶片反射率光谱和一阶导数光谱数据的相关分析，可以看出全生育期和不同生育阶段的叶绿素敏感波段范围。
