论大学生受教育权

受教育权已成为各国宪法和法律所保障的公民基本权利之一。大学生受教育权作为我国公民的一项法律权利，在性质上具有综合性的特点，既具有与一般主体相同的宪法性权利性质，由具有作为大学生与其他主体的受教育权利不同的特点。在受教育权利的内容上既具有实体性的权利，又具有程序性的权利。

沈从文小说中水意象的文化解读

在以湘西为题材的小说中,沈从文常将人事的哀乐置于水边加以描绘,水,不仅仅是沈从文小说创作的背景,而且水还有着极为丰富的文化内涵。水既给了沈从文创作的灵感和智慧又给了他孤独的享受,在作品中,水,还成为阻隔有情人相会的不可逾越的障碍。

几何中的调和分割及应用

“调和分割”又称“调和共轭”,它是交比研究中的一个重要特例,也是贯穿大学《高等几何》课程的一个重要概念,涉及到高等几何中的内容：对合的性质、完全四点型的调和分割、完全四线型调和分割以及拉盖尔定理等,并且应用它可解决几何中的相关问题．     

孤独的歌者：Whitman诗歌同性恋主题探微——基于In Paths Untrodden个案研究

性和性爱是Whitman诗歌的一个主要且重要的主题。在饱受争议的组诗Calamus中,诗人大胆地将这一主题磊落铺陈。In Paths Untrodden是Calamus的序诗,对理解整首组诗具有至关重要的意义。文章借鉴性别研究理论,结合诗人的时代背景、诗学理念和人生经历,对InPaths Untrodden这首诗进行个案研究,尽量还原、复活诗人当时的创作意图,重新理解、深入解读Whitman的这些性诗,领略诗人在19世纪的历史环境下用模糊暧昧的意象和迂回隐约的暗示来表达自己真情实感和思想的策略与技巧。Whitman从隐藏、变形到尽量体现自己原来的创作意图,这一系列变化反映了时代变迁下性观念的改变,以及对同性恋现象和行为的理解、接受和宽容。     

对新时期汉语语法规范化问题的思考——基于对前新时期语法规范化进程和观念的梳理与分析

新中国成立后的近30年语法规范化的研究与实践,在语法规范标准的确立、语法规范观及其理论研究、个案剖析等方面取得了很大成绩,但其中也有不尽如人意之处：＂匡谬正俗＂的模式和方法致使语法规范批评多,引导少;主观规定多于客观引导,规范标准落后于语言实践;忽视语言的约定俗成和习非成是,用逻辑规则解释语法现象;学术领域注重语言本体研究,忽视语言应用研究,影响了语言规范化问题的深入探讨。在新的历史时期,为真正体现其功能,避免少出、不出偏误,语法规范就必须以人为本,以＂用＂为据。     

Morphological and biochemical responses of Oryza sativa L. (cultivar MR219) to ion beam irradiation

Objective

Heavy ion beam, which has emerged as a new mutagen in the mutation breeding of crops and ornamental plants, is expected to result in the induction of novel mutations. This study investigates the morphological and biochemical responses of Oryza sativa toward different doses of carbon ion beam irradiation.

Methods

In this study, the dry seeds of O. sativa were irradiated at 0, 20, 40, 60, 80, 100, and 120 Gy, followed by in-vitro germination under controlled conditions. Morphological and biochemical studies were conducted to investigate the morphological and physiological responses of O. sativa towards ion beam irradiation.

Results

The study demonstrated that low doses (10 Gy) of ion beam have a stimulating effect on the height, root length, and fresh weight of the plantlets but not on the number of leaves. Meanwhile, doses higher than 10 Gy caused reductions in all the morphological parameters studied as compared to the control samples. The highest total soluble protein content [(2.11±0.47) mg/g FW] was observed in plantlets irradiated at 20 Gy. All irradiated plantlets were found to have 0.85% to 58.32% higher specific activity of peroxidase as compared to the control samples. The present study also revealed that low doses of ion beam (10 and 20 Gy) had negligible effect on the total chlorophyll content of O. sativa plantlets while 40 Gy had a stimulating effect on the chlorophyll content. Plantlets irradiated between 40 to 120 Gy were shown to be 0.38% to 9.98% higher in total soluble nitrogen content which, however, was not significantly different from the control samples.

Conclusions

Carbon ion beam irradiation administered at low to moderate doses of 10 to 40 Gy may induce O. sativa mutants with superior characteristics.     

Simulation games in science education‡

The astronomy concepts of 345 young people were studied over a 10‐year period using a multi‐media, multi‐modal methodology in a research design where survey participants were interviewed three times and control subjects were interviewed twice. The purpose of the research was to search for evidence to clarify competing theories on conceptual coherence versus knowledge‐in‐pieces, distinguishing between coherence as revealed in the representational systems at any particular stage in a young person’s development and the changes evident in mental growth thereafter. Thus five research questions concerned with the elements and structure of understanding were investigated: (1) conceptual coherence shown as patterns of high correlation of concept representations between the media used to assess subjects’ understanding within a survey, as well as (2) coherence revealed as consistency of representation of those concepts across media and modalities; (3) enhanced conceptual understanding and skill through repeated interviews across (longitudinal) surveys, as young people develop their knowledge; (4) cultural similarity in subjects’ representations of basic static concepts (e.g. the shape of the Earth); and (5) improved understanding of basic dynamic concepts (e.g. the motion of the Earth) and complex dynamic concepts (e.g. seasons and eclipses), through “knowledge‐skill compounding”. The research findings supported conceptual coherence and rejected the counter argument of knowledge‐in‐pieces (at an alpha level of .05). Further research is recommended to replicate current research in cultures other than those of China and New Zealand studied here to confirm the view that cognition and knowledge are inherently coherent in young people.
