Overall,our results confirm that phytoliths can provide reliable and robust estimates of MAP, MAT,Humi and ***,WA-PLS is a robust calibration method for quantitative palaeoenvironmental reconstruction based on phytolith data.

本文为凸二次规划问题提出一个光滑型方法,它是Engelke和Kanzow提出的解线性规划的光滑化算法的推广。其主要思想是将二次规划的最优性K-T条件写成一个非线性非光滑方程组,并利用Newton型方法来解其光滑近似。本文的方法是预测-校正方法。在较弱的条件下,证明了算法的全局收敛性和超线性收敛性。

第七届全国系统与进化植物学青年学术研讨会

作者： PAN Jin, WANG Chao, SANG Tao, ZHANG Da-Ming (1. Laboratory of Systematic and Evolutionary Botany, Institute of Botany, chinese academy of sciences, beijing 100093, china 2. Department of Plant Biology, Michigan State university, MI 48824, USA)

The genus, Peaonia, is a systematically isolated unit with a common placement in the unigeneric family Peaoniaceae. Due to its morphological continuity and hybrid origin, Peaonia proves to be a phylogenetically and taxonomically complex group and in turn a highlight of the systematic and evolutionary researches. With the extensive application of molecular tools, the phylogeny of Paeonia has been previously reconstructed based on DNA sequences from multiple genie and intergenic regions, including the cpDNA gene matK, two intergenic cpDNA spacers, and the nrDNA ITS region and two loci of the low-copy nuclear gene alcohol dehydrogenase genes. These molecular phylogenies were well established among most of the taxonomic species. However, the evolutionary relationships and

Price leadership strategy or branding strategy:an empirical test of indigenous chinese exporters

引用

Journal of Southeast university(English Edition) 2008年第S1期24卷 174-179页

作者： Chen Xi1 Hu Zuohao1 Zhao Ping1 Song Hua2(1 School of Economics and Management, Tsinghua university, beijing 100084, china)(2 School of Business, Renmin university of china, beijing 100872,china)

The effects of price leadership strategies and branding strategies on the export performance of indigenous chinese exporters with a focus on developing country markets and developed country markets are examined based on the principles of strategy-environment co-alignment and marketing segmentation theory. Findings suggest that when focusing on developing country markets, the use of a branding strategy is more likely to enhance export performance. When focusing on developed country markets, neither the use of a price leadership strategy nor the use of a branding strategy enhances export performance. Finally, theoretical and managerial implications of the findings are discussed.

本文企图在更为广阔和统一的思想语境里对话性地诠释巴赫金思想的精髓。多样性的巴赫金思想并非散沙一盘,对话理论及其人文精神是它的精髓。巴赫金终生徜徉在哲学、语言学、社会学和诗学各人文学科领域,而其中心工作就是建构自身的对话理论,他以之贯串于所有的人文学科各领域的研究中,而人文精神是巴赫金的对话理论体现出的核心精神,对话理论在其根底上是关于人的理论,是巴赫金终生为人而斗争的理论结晶,闪耀着人文精神的光辉,它以人为对象,关心人的主体建构,关心人的存在和命运,关心人的平等和自由。就诗学来说,巴赫金的杰出之处在于,在20世纪“语言论转向”的文化语境里,他既能以复调小说理论这种对话理论的变体来阐释陀思妥耶夫斯基小说的艺术形式。

关键词：巴赫金对话理论人文精神复调小说
