Genetic analysis for brix weight per stool and its component traits in sugarcane （Saccharum officinarum）

Brix weight per stool (BW) of sugarcane is a complex trait, which is the final product of a combination of many components. Diallel cross experiments were conducted during a period of two years for BW and its five component traits, including stalk diameter (SD), stalk length (SL), stalk number (SN), stalk weight (SW), and brix scale (BS) of sugarcane. Phenotypic data of all the six traits were analyzed by mixed linear model and their phenotype variances were portioned into additive (A),dominance (D), additive×environment interaction (AE) and dominance×environment interaction (DE) effects, and the correlations of A, D, AE and DE effects between BW and its components were estimated. Conditional analysis was employed to investigate the contribution of the components traits to the variances of A, D, AE and DE effects of BW. It was observed that the heritabilities of BW were significantly attributed to A, D and DE by 23.9%, 30.9% and 28.5%, respectively. The variance of A effect for BW was significantly affected by SL, SN and BS by 25.3%, 93.7% and 17.4%, respectively. The variances of D and DE effects for BW were also significantly influenced by all the five components by 5.1%～85.5%. These determinants might be helpful in sugarcane breeding and provide valuable information for multiple-trait improvement of BW.     

论王阳明“意之动”的主体意蕴

王阳明认为,＂意＂指心之发动处;＂意之动＂则是善恶出现的标志,是发动之心分殊之始,也是本心与天理相融亦分的状态。＂意之动＂从＂心之体＂产生而建立在＂心之体＂上,生发＂意之动＂的主体意蕴是无善无恶的;＂意之动＂生于内而发于外,发于外的主体显现出有善有恶的意蕴;而处于内与外之间的主体则呈现主体兼性意蕴。     

协奏曲的钢琴改编谱演奏初探

在演奏管弦乐队协奏曲总谱改编的钢琴谱时,应当具备对文本（乐谱）的分析能力。而当以钢琴替代乐队时,钢琴协奏者实际上就承担着双重的责任：演奏者、指挥者。对此,钢琴协奏者必须有明确的认识,建立起积极而非被动的协作意识。具备理性的分析和认识是第一步,但毕竟协奏曲钢琴部分的演奏与钢琴独奏有相当明显的区别,因此,在演奏理念和演奏技巧上也要作相应的调节。     

中小城市英文标识语的错误现象、成因与对策分析

随着全球经济一体化及对外开放的进一步深入,我国很多中小城市也迎来了不少外国商人与游客.因此,这些城市的公共场所逐渐添加了一些英文标识语.这本是一件方便外国友人的好事情,但遗憾的是,这些英文标识语目前还存在着一些错误及不规范现象,这不但不能给外国友人带来方便,还有可能造成误解.造成这些错误的原因也多种多样,但只要译者事先做好充分的调查研究,了解英文标识语的重大作用,翻译时认真仔细,这样的错误都是可以避免的.

On Sample-Size Calculations for Precise Contrast Analysis in ANCOVA

The analysis of covariance (ANCOVA) is a useful statistical procedure that incorporates covariate features into the adjustment of treatment effects. The consequences of omitted prognostic covariates on the statistical inferences of ANCOVA are well documented in the literature. However, the corresponding influence on sample-size calculations for precise interval estimation has not been fully evaluated. This article aims to explicate the deficiency of approximate methods for ignoring the stochastic nature of covariate variables and to present exact approaches for precise interval estimation of treatment contrasts under the assumption that the covariate variables have a joint multinormal distribution. The desired precision of a confidence interval is assessed with respect to the control of expected half-width and to the assurance probability of interval half-width within a designated value. Numerical appraisals show that the suggested approaches outperform the approximate formulas for the two precision considerations.
