情绪、情感,是人对客观事物是否符合自己的需要、愿望和观点而产生的体验。是人对客观事物的一种特殊的反应方式。表现为高兴、欢乐、忧愁、悲伤、赞叹、喜爱、惊恐、厌恶等。初中生南于年龄小、知识根底浅、活泼好奇。偏爱形象思维。乐于接受教师的富于情趣的教学方式。为此。在思想政治课的教学中。应注重情感的感化、熏陶,以提高其认知能力。 相似文献

禁止权利滥用随着法权观念的变迁,逐渐由一种道德观念演变成为民法的一项基本原则,承载起平衡个人利益与社会利益的历史使命,并成为走向权利时代的必要立法规制。本文将沿着理论——实践、历史——现实的研究理路,试图在澄清禁止权力滥用原则的基本理论的基础上探讨其存在的正负价值,在对禁止权利滥用原则导致的危机防范思考中探寻其合理的构建路径,以真正实现此原则在协调权利分配和维护公平正义方面所应当发挥的作用。 相似文献

A fiberless seed mutant (fl) was identified in a commercial cotton (Gossypium hirsutum L.) variety Xu-Zhou 142 (FL). This phenotype is associated with lack of fiber cell initiation in the outer integument of
the ovule, as was characterized by analysis of genes related to fiber differentiation and development. Two genes, fl-E6 and
FL-E6, were cloned from fl-integument cells and FL-fiber or integument cells, respectively. Compared with FL-E6, fl-E6 showed
a dramatic change in nucleotide sequence: (1) FL-E6 contained a tandem repetitive sequence in which GGCTCA (Gly-Ser) is repeated
five times between the 82nd and the 93rd codon from the first ATG codon, while in fl-E6 the same sequence is repeated four
times; (2) The fl-E6 gene encodes a polypeptide of 241 amino acids but lacks two codons between the 90th and 93rd codon and
three between the 171st and 174th relative to FL-E6; (3) There are also 12 nucleotide substitutions which would result in
7 amino acid differences between fl-E6 and FL-E6. Analysis of RT-PCR and Northerm Blot showed that expression of the fl-E6
gene is suppressed in the fl-integument cells, but highly expressed in FL-fiber cells. The difference between fl-E6 and FL-E6
may be associated with lower expression of fl-E6 in the fl-integument cells. Searches of protein databases with the FL-E6
gene sequence showed similarity to the protein backbones of two arabinogalactan-proteins (AGPs), one from the filtrate of
suspension-cultured cells ofPyrus cornmunis (AGPPc2) and the other fromNicotiana alata (AGPNa2). Although the function of the FL-E6 protein in differentiation and development of cotton fiber cells is not known,
the data indicate that the mutation of fl-E6 gene from FL-E6 gene may inhibit the fiber cell initiation from epidermal cells
of the outer integument of the ovule.
