WOMBAT A tool for mixed model analyses in quantitative genetics by restricted maximum likelihood （REML）

WOMBAT is a software package for quantitative genetic analyses of continuous traits, fitting a linear, mixed model; estimates of covariance components and the resulting genetic parameters are obtained by restricted maximum likelihood. A wide range of models, comprising numerous traits, multiple fixed and random effects, selected genetic covariance structures, random regression models and reduced rank estimation are accommodated. WOMBAT employs up-to-date numerical and computational methods. Together with the use of efficient compilers, this generates fast executable programs, suitable for large scale analyses. Use of WOMBAT is illustrated for a bivariate analysis. The package consists of the executable program, available for LINUX and WINDOWS environments, manual and a set of worked example, and can be downloaded free of charge from http://agbu. une.edu.au/~kmeyer/wombat.html     

Genetic analysis of fruit shape traits at different maturation stages in sponge gourd

The fruit shape is important quantitative trait closely related to the fruit quality. However, the genetic model of fruit shapes has not been proposed. Therefore, in the present study, analysis of genetic effects for fruit shape traits （fruit length and fruit perimeter） in sponge gourd was conducted by employing a developmental genetic model including fruit direct effects and maternal effects. Analysis approaches of unconditional and conditional variances were applied to evaluate the genetic behavior of fruit shape traits at economical and physiological maturation times. The results of variance analysis indicated that fruit length and fruit perimeter were simultaneously affected by fruit direct genetic effects and maternal effects. Fruit direct genetic effects were relatively more important for fruit shape traits at whole developmental period. The gene expression was most active at the economical maturation stage （1-12 d after flowering） for two shape traits, and the activation of gene was mostly due to direct dominance effects at physiological maturation stage （13-60 datter flowering）. The coefficients due to different genetic effects, as well as the phenotypic correlation coefficients, varied significantly between fruit shape traits themselves at various maturation stages. The results showed that it was relatively easy to improve fruit shape traits for industrial purpose by carefully selecting the parents at economical maturation stage instead of that at physiological maturation stage.     

基于遗传算法求解TSP问题的算法设计

TSP是一个典型的组合优化问题,并且是一个NP难题,其可能的路径总数与城市数目n是成指数型增长的,所以一般很难精确地求出其最优解,因而寻找出有效的近似求解算法就具有重要的意义.现提出一种求解TSP问题比较有效的遗传算法,从其数学模型、遗传算子、评估函数、种群多样性等方面对算法进行了分析,结果表明提出的算法在求解TSP问题上是有效的.     

弘扬长征精神的道德价值,重塑“90后”大学生道德品质

长征是史无前例的英雄史诗,具有永恒的道德价值和永久的魅力。目前,我国"90后"大学生频现道德失范,高校德育面临挑战。这就需要充分发掘长征精神的道德价值,培养"90后"大学生形成良好的道德品质。     

图式理论与大学英语写作

写作作为一种重要的输出形式,需要学生有较高的语言综合运用能力。在教学中,利用图式理论,可以帮助学生摆脱这种尴尬的境地,有效地提高他们的写作水平。关键在于启发学生主动思考,通过阅读来积累语言图式,与时俱进增强内容图式,了解形式图式并整理其思维模式。     

《史通》对《文心雕龙》宗经史学观的批判

刘知几《史通》的创作受到了刘勰《文心雕龙》的影响,主要体现在撰述形式和史学思想上。刘勰有着宗经的史学观,推崇言经《尚书》和事经《春秋》,主张尊贤隐讳。刘知几批判性地继承了刘勰的史学观,他从史学家的角度对《尚书》和《春秋》展开了批判,提出了隐讳的限度问题,对刘勰的宗经史学观进行了修正。刘知几写作《史通》是出于纯洁的史学理想,而且他和刘勰对经书的喜好情感不同。     

朝鲜南龙翼诗评中比较批评之运用——以对中国诗的批评为中心

南龙翼将比较批评广泛运用到他的诗评活动中,他对唐代诗歌给予了极大的关注,包括比较批评初唐诗、盛唐诗、中唐诗、晚唐诗,对宋诗、明诗也以比较批评方式论之,折射出了南龙翼古典诗学批评方式所蕴涵的独特的艺术魅力。     

“清”:作为文学审美范畴的确立

刘勰以"清"论文,涉及到对作品语言、文风、文体等各个方面的评价,主要是指诗文言辞的"清丽"和整体风貌的"清峻"等,核心是指以华美的言辞鲜明地表达思想内容,自然流畅、意气峻发,给人一种整体的审美愉悦感。"清"作为文学审美范畴,其地位是在《文心雕龙》中正式确立的。     

长征精神融入医德培育研究

伟大的长征铸就了伟大的长征精神,长征精神和医德精神有着内在的价值共通。在医学类高校中培育新时代仁心仁术的医者之德,长征精神不失为出色的叙事文本。可以通过解释长征精神的内在含义来分析它对医德培育的独特精神性价值和工具性价值,联通长征精神和医德培育研究的内在价值和底层逻辑。
