综合性大学野外实践教学模式初探——以武汉大学庐山地理野外综合实习为例

文章以武汉大学资源环境科学学院庐山地理野外实践教学为例,从野外实践的教学内容、教学环节、教学方式、教学考评指标体系以及野外实践教学中相关理论教学的学术争鸣等几个方面,构建了综合性大学野外实践教学的基本模式,并针对性地提出了野外实践教学的保障体系,对建设规范、成熟的野外实践教学模式进行了有益的探索。     

Models of English and Chinese word reading for adolescent Chinese–English bilinguals

These two studies examined the processes underlying English and Chinese word reading in Chinese–English bilinguals in relation to their experiences with their second language (L2), as determined by length of time in an English-speaking environment. Phonological awareness, morphological awareness and vocabulary measures were administered in English and Chinese to adolescents and young adults living in Canada. The results show that similar word reading processes were used to read English and Chinese for the bilinguals who were recent immigrants and had less exposure to English. Specifically, vocabulary knowledge was directly related to English and Chinese word reading in the more recent immigrants. However, phonological awareness was not related to English word reading in this group. Conversely, reading processes in the two languages were less similar for participants who were long-term immigrants. In the long-term immigrant group, English reading was related to phonological awareness. The writing system of the first language (L1) exerted an influence on L2 reading and the degree of influence was related to language experience.

从失落到理解--文学接受活动中主体期待遇挫现象析

在具体的文学接受活动中,接受主体常常伴随着期待指向上的遇挫,从而造成接受心理上的失落.这一方面是由于主体期待视野、审美经验、前理解的先在性制约;另一方面本文的艺术探索性和创造性的特点,给主体解读提供了客观性压力和难度.而接受主体审美追求的努力和本文艺术内涵的感召,使主客体走向交流、契合、理解成为必然.     

我国商事信用立法调整机制的分析与重塑--一种法律经济学的观点

商事信用是指以契约为保障的为了未来收益的交易经济行为。在商事活动一次性博弈当中，商事主体考虑的因素是财产权、信任可观察度、惩罚成本；当商事信用活动是一个可重复的博弈时，商事主体考虑的则是信任的收益和成本。与此相关的法律因素是法律的稳定性与中立性、财产权制度、商事登记制度、法律实施机制等。我们应该从上述四个方面重塑我国商事信用的法律调整机制，维护商事信用秩序。     

边疆民族地区中小学体育教学现状调查及对策研究

西部大开发给西部民族地区的教育事业带来了前所未有的发展机遇,学校体育教育也随着基础教育的深化改革取得了长足的进步,但与沿海一带发达地区相比还存在着较大差距.其中,体育意识薄弱,体育经费不足,场地器材等体育设施缺乏,以及体育师资数量不足、专业水平较低等,是制约边疆民族地区中、小学体育教育发展的主要因素.笔者通过大量的碉研和实践,提出了在边疆民族地区中、小学体育教学中融入民族民间体育内容,以利用本地资源因地制宜的教学思路,以供大家参考.

Accumulation of chromium by <Emphasis Type="Italic">Commelina communis</Emphasis> L. grown in solution with different concentrations of Cr and L-histidine

Hydroponic experiments conducted to examine the chromiun uptake by C. communis in the presence of different Cr concentrations (Cr⁶⁺ 100 and 200 mg/L, respectively) and free histidine supplementation (0.5 and 1.0 mol/L) showed that shoot and root growth of C. communis decreased greatly with increasing Cr concentrations in the medium; and that the species was a typical excluder since it accumulated high concentrations of Cr in roots but comparatively low concentrations in shoots. Chromium in shoots and roots of Cr₄^2?-supplied plants ranged from 329–1880 and 3788–4240 mg/kg DW, respectively, while those of Cr₄^2?-histidine-supplied plants ranged from 478 to 629 mg/kg and 4157–4303 mg/kg DW, respectively. With Cr present in the hydroponic solution, C. communis accumulated more Cr in its tissues. Increasing histidine application to the solution significantly increased chromium accumulation in the plant tissues but could not alter the accumulation pattern of plants although it induced a higher concentration of Cr in its shoots and roots. These features suggested that C. communis may serve as an alternative species in a constructed wetland for phytoextraction treatment of Cr-containing wastewater and for phytostabilization of Cr mining spoils.     

组合导数分光光度法同时测定钼和钨的研究
