汉语色彩词衍生法之探究

汉语色彩词经历从依附实物名词,到抽象为独立表色的过程后,在已有的单音节色彩词的基础上,从简单到复杂衍生的方法大致有七种:借物法、比况法、组合法、修饰法、通感法、重叠法、外来法。色彩词,乃至汉语语词的不断衍生,有助于人们生动而形象地反映客观世界,传递思想。     

植物生长调节物质对矮生一品红不定芽增殖的影响

以几种矮生一品红为材料,研究了植物生长调节剂BA,KT,IAA对不定芽增殖的影响.结果表明,影响一品红芽增殖的主要因素是细胞分裂素,以BA的增殖效果较好.不同品种(自由红、彼德之星、金钱豹、塔巴璐卡)芽增殖所需植物生长调节剂的浓度有所不同,矮生一品红试管苗芽增殖的适宜培养基为MS+BA0.5—2.0mg/L+IAA0.25—0.50mg/L.     

Intra-industry diversification effects under firm-specific contingencies on the demand side

How do firm-specific, demand-related factors influence the relationship between intra-industry diversification (IID) and performance? Recent findings regarding the performance effects of IID depict a complex picture with curvilinear relationships and several contingencies. However, firm-specific contingencies on the demand side have remained unexplored. We analyze how IID relates to firm performance (market share) in the German automotive industry using panel data between 1999 and 2008. We specifically focus on a firm's high-quality brand image as a demand-side contingency. We find support for our hypotheses of complex curvilinear relationships as well as for moderating effects of brand quality. Our results have significant theoretical implications for the IID literature.     

“没有晚清,何来五四”与现当代文学学科话语增生

"没有晚清,何来五四"对晚清文学知识考古式重返,把现代文学起点推到晚清,拓宽了现代文学疆界,并从对现代起源的关注转向如何想象并谈论中国"现代"的方式,引发了现当代文学研究范式的转换。论断对晚清现代性想象的释放,引发十七年文学"反现代的现代性"的探讨,使其在"革命中国"的阐释中具有了知识范畴的独立性和类似"乌托邦"的价值品格。而寻找中国现代性的努力暗合了中国作为大国经济崛起的"现实",这种承认的政治让现代性变成政治正确的概念而空洞化,重新落入西方思维模式中。对论断的反思是研究者超越时代限定并使现当代文学学科与研究者获得独立品格,走向成熟的关键。     

Biologically Motivated Cancer Risk Models

A two-stage dose response model is proposed for use in cancer risk assessment. The model assumes that transformation probabilities and cellular dynamics are exposure- and time-dependent.     

朝鲜核战略与东北亚地区的核扩散——兼谈对中国周边安全的影响

朝鲜之所以进行核试验，与先前印度、巴基斯坦等国家的“成功”先例不无关系。朝鲜的核武装可能带来的严重后果，会使原本就蠢蠢欲动的日本、韩国甚至台湾等纷纷步朝鲜后尘，有可能走上核开发之路。届时，东北亚必将引发核“多米诺骨牌效应”，这不仅会导致东北亚局势严重不稳，也会使中国成为唯一一个被核国家包围的国家。     

纳米管的生物效应和毒性

在使用3-(4,5-二甲基-2-噻唑)-2,5-二苯基溴化四唑(MTT)比色法和毒物学方法研究由碳纳米管引起的生物组织——鸡胚胎纤维原细胞的性质的改变,以及碳纳米管对细胞产生的毒性后,发现碳纳米管会对鸡胚胎纤维原细胞增殖造成影响,不过它对这个生物组织的毒性很小,大约一级。     

Impact of product proliferation on the reverse supply chain

Product variety is one of the most important advantages in highly competitive markets. However, excessive product proliferation's reducing the profit margin has caused increased focus on developing a management method for maximal profit. In a closed-loop supply chain, product proliferation affects the reverse supply chain as well as the forward supply chain. Although increasing the number of product types can better satisfy diverse customer needs, complexity in the product recycling, remanufacturing, and resale processes may erode a firm's overall profits. In this study, we develop a mathematical model for analyzing a capacitated reverse supply chain consisting of a single manufacturer and multiple retailers. We reveal closed-form solutions for the optimal batch size and maximal profit, and discuss managerial insights into how the number of products and other factors can affect both batch size and profit. Finally, we investigate the relationship between product proliferation and the choice of logistics strategy.     

政治领导与机制设计：导弹扩散治理机制的成长

导弹作为一种最有威慑力的武器运载系统,已引起世界各国对导弹扩散治理机制构建的积极关注。但由于机制构建中权力分配结构失衡、共同利益基础薄弱、基本理念和道义准则存异等因素,使得导弹扩散治理机制的成长到目前仍面临着巨大压力。加强机制谈判中的政治领导是走出导弹扩散治理机制成长困境的有效方法,也是最现实的出路。在完善导弹扩散治理机制的谈判过程中,结构型领导有利于将结构性权力转化为谈判筹码,企业家型领导导致利益的汇聚与整合对于机制成长至关重要,智慧型领导则能为机制构建提供相关参与方都较容易接受的全新理念。     

产品扩散策略对企业绩效的影响

从市场需求理论和消费者行为理论出发,引入产品复杂度的调节作用,以中国汽车企业作为研究样本,选取32家中国车企2008～2012年的面板数据,对多次级市场和同一市场两种不同的产品扩散策略与企业绩效关系及产品复杂度在策略-企业绩效关系中的调节作用进行分析.实证结果表明,两种产品扩散策略与绩效之间由负向关系转为正向关系,即两种产品扩散策略与企业绩效呈U型关系;产品复杂度加强了多次级市场产品扩散策略与绩效之间的关系,而弱化了同一市场产品扩散策略与绩效的关系.企业应根据自身的情况,选择合适的扩散方式,合理灵活地利用产品复杂度的调节作用,对企业绩效会起到事半功倍的效果.
