 [PDF]

Modern Marketing (MOM) , 2015, DOI: 10.12677/MOM.2015.52003
Abstract:
客户推荐是B2B市场中供应商能力营销的主要工具和方式。本文在分析客户推荐对供应商能力营销作用的基础上,指出供应商利用客户推荐开展能力营销的四种具体方式:展示推荐客户名单和推荐信、宣传成功故事与典型客户案例、散发新闻报道材料和媒体资讯、组织潜在客户参观推荐客户的工厂或车间。这些结论在理论上为研究客户推荐这种新型营销资产提供一些新的观点和知识,在实践上为产业供应商利用客户推荐和开展能力营销提供新的思路。
Customer reference is a key tool and way for suppliers to marketing their competencies to cus-tomers in B2B markets. This paper put forward four methods of competence marketing based on the role of customer reference in marketing competence: showing referrer customer lists and their reference letters, communicating successful stories and customer cases, distributing news material and media reports about their technology successes, and arranging potential customers to visit referrer customer’s firm. These conclusions provide some new opinions and insights for other scholars to research this topic, and offer some different approaches for industrial suppliers to do marketing of competence to customers.
日语拒绝发话行为的非言语行为的使用特征
Nonverbal Behavior Using Features of Japanese People in Refusal Locutionary Act
 [PDF]

玉琴,
Modern Linguistics (ML) , 2015, DOI: 10.12677/ML.2015.34020
Abstract:
本文基于视频语料库JV-Finder,以拒绝发话行为中的非言语行为为研究对象,使用ELAN多媒体转写标注软件,编辑非言语行为公式,试分析了日本人在拒接发话行为过程中的非言语行为使用情况及使用特征。通过本次研究得出,日本人在拒绝发话行为中,非言语行为比例占39%,其中以“视线”、“手势”、“鞠躬”为最常使用。并且,非言语行为的使用方式分为两种,伴随言语行为使用和独立使用;在日语拒绝表现中,非言语行为出现的位置多在拒绝发出时和拒绝完成后;根据其使用的情景,可将非言语行为划分为“实质性”和“非实质性”。拒绝行为中,谈话双方的话语权转换也很微妙。一次拒绝行为的完成可能是一次话轮转换即可,也可能要经过3次甚至3次以上的话轮转换才可完成,这要视谈话内容的重要性及双方的社会关系而决定。
Based on JV-Finder video corpus and taking the nonverbal behavior as research object, this paper has analyzed nonverbal behavior using status and using features of Japanese people in refusal lo-cutionary act by ELAN multimedia writing software and editing nonverbal behavior formula. This research shows that in refusal locutionary act, nonverbal behavior takes 39% and frequently used by “sight”, “gesture” and “bow”. There are two ways of nonverbal behavior: used with verbal beha-vior and used independently. In refusal locutionary act, most of the nonverbal behavior appears when refusing or after refusing. According to the using status, nonverbal behavior can divided into intentionality and supportability. In refusal act, discourse power conversion is also subtle. A refusal act needs only one turn taking or more than three turn takings depends on the importance of contents and social relations of the two communicators.
胚胎干细胞自我更新相关信号转导途径及信号分子

科学通报 , 2005,
Abstract: 胚胎干细胞(embryonic stem cells,ES cells)是从囊胚期内细胞团(inner cell mass,ICM)分离得到的,在体外具有无限或较长期的自我更新能力,并能在特定的诱导条件下分化成各种组织特异性细胞.鉴于此种特性,ES细胞在临床上具有极其广阔的应用前景.但是要将ES细胞成功的应用于临床,必须解决的首要问题是胚胎干细胞是如何实现自我更新及定向分化的.某些小鼠的ES(mES)细胞可以在LIF等外源性细胞因子的作用下在体外维持自我更新.研究表明,LIF维持自我更新的能力是通过LIF-LIFR-JAK-STAT3途径实现的,其中STAT3在该途径中起关键作用.Oct-3/4也是维持ES细胞多能性的重要分子之一,它与其辅助分子Sox2,Rox-1共同参与调节胚胎的正常发育.Nanog是最近发现的一个同源盒转录因子,被认为在ES细胞的全能性维持中起关键作用.此外,BMP,Wnt,ERK途径也在这一过程中起重要作用.本文中我们对近年来发现的有助于胚胎干细胞自我更新的相关信号转导通路做了概括综述,主要有LIF-STAT3途径、Oct-3/4和Nanog信号分子.虽然它们之间是通过怎样的模式相互影响和协调起作用还不是十分清楚,但为我们以后的研究指明了方向.

Abstract:

随着经济发展和人类活动的干扰,西南生态脆弱区的生态脆弱性特征进一步凸显。本文采用生态足迹模型,以云南、贵州、四川、广西、重庆五省(自治区、直辖市)为案例区,定量计算了1990年~2008年的生态足迹,从而揭示西南生态脆弱区生态承载力的时空格局。结果表明:1) 从区域整体来看,1990年~2008年,人均生态足迹呈递增趋势,由0.7508 hm2增加到2.1803 hm2,增长了2.90倍;人均生态承载能力总体呈减少趋势,由0.5728 hm2下降到0.4696 hm2,下降了18.01%;生态消耗水平的增加与承载能力的下降,导致西南生态脆弱区人均生态赤字逐年增加,对外来资源的依赖程度增强。2) 从生态足迹和生态承载力生物生产性土地构成来看,耕地的生态空间供给最大,林地和建设用地生态空间供给位列其次;近20年来研究区草地和水域生态供给空间呈减少趋势,化石燃料土地的人均生态足迹增幅最大。3) 从空间格局来看,1990年~2008年西南五省(自治区、直辖市)人均生态足迹均呈增加趋势,其中广西增幅最大,四川最小;人均生态承载力均呈减少趋势,除四川呈先减后增再减的特征外,其他地区都呈先增后减的态势,云南为西南生态脆弱区人均生态承载力减少的主因;1990年~2008年西南五省(自治区、直辖市)生态赤字均呈增加趋势,其中云南生态赤字水平增幅最快。
With the economic development and human disturbance, the fragility in southeast ecological fragile area is more remarkable. This paper took Yunnan, Guizhou, Sichuan, Guangxi, Chongqing as a case, used ecological footprint model to analyze the spatial-temporal pattern of ecological capacity in southwest ecological fragile region from 1990 to 2008. The results showed that: 1) For the region as a whole, from 1990 to 2008, the ecological footprint per capita of southwest ecological fragile region showed an increasing trend, from 0.7508 hm2 to 2.1803 hm2, about 2.90 times; The ecological capacity per capita showed a decreasing trend, from 0.5728 hm2 to 0.4696 hm2, about 18.01% decreasing rate; The ecological deficit per capita increased year by year owing to the increase of ecological consumption and the de-crease of ecological capacity. Southwest ecological fragile region depended on external resources increasingly. 2) From the composition of biologically productive land of ecological footprint and ecological, cultivated land supplied the big-gest capacity, followed by forest and construction land. The capacity supply of grass land and water area decreased nearly 20 years. And the ecological footprint per capita of fuel land increased the biggest increment. 3) In the perspec-tive of geographical pattern of change from 1990 to 2008, the ecological footprint per capita of five regions in south-west showed increasing trend. Guangxi displayed the largest increment, while Sichuan the smallest. The ecological ca-pacity per capita of five regions performed decreasing trend, that is, except Sichuan showed the character of de-crease-increase-decrease, other regions showed the character of increase-decrease. Yunnan contributed the most de-crease of ecological capacity per capita of southwest ecological fragile region mainly. From 1990 to 2008, the five re-gions’ ecological deficit per capita showed increasing trend, while Yunnan increased fastest of all.

Abstract:
为了提高突发事件应急救援的效率,应急物资配送优化是应急救援的关键环节之一。本文结合应急物资的特殊性,分析了自然因素、事故性质和基础设施对应急物资配送方案选择的影响,构造出多应急点多种类物资条件下应急物资调运优化模型,并利用免疫克隆算法进行求解。最后,以某地区应急事件为例,分析了各应急点及各路段的受影响程度,采用Matlab计算平台,求解出最优的应急物资配送方案。结果表明:免疫克隆算法可以避免早熟收敛现象,能够快速有效地收敛到最优解,是求解应急物资配送问题的一种有效方法。
Emergency material scheduling is one of the key links in order to improve the efficiency of the emergency rescue. Combining with the particularity of the emergency material and analyzing the influence of natural factors, accident character and base installation to selecting emergency supplies distribution plan, emergency supplies scheduling optimization model that is based upon more emergencies points and more kinds supplies is constructed. In addition, this issue is solved by the immune clonal algorithm. Taking emergency events of one region as an example, this paper analyzes the influence degree of every emergency points and every road segments. And by using Matlab software, an optimal distribution scheme of emergency supplies is proposed. The results show that the immune clonal algorithm can avoid form the premature convergence problem and is more efficient in optimization of multi-variable function, moreover, it is an efficient method to resolve the problems of emergency supplies distribution.

Abstract:
人民币跨境流通是当前我国推进人民币国际化战略的关键环节和重要步骤。随着人民币跨境流通规模的显著增大,必然对当前所处的金融生态提出更高要求,它不啻带来诸多负面冲击,而且还倒逼加快改善我国的金融生态。因此,推进人民币跨境流通的同时必须着力改善我国的金融生态,建立更加符合现代化的金融服务支撑体系,减弱人民币跨境流通对金融生态的负面影响,提升正向效应,从而更好地发挥其正向导引作用。
RMB cross-border circulation is the key part and the important step of promoting the RMB inter-nationalization strategy. With the expanding to more countries and areas worldwide, the circulation of RMB requires that China should provide a perfect financial ecology under its impacts. As a result, with improving RMB cross-border circulation, China should also improve its financial ecology at the same time, setting up the modern financial service support system which abates the negative impact of the financial ecology by RMB cross-border circulation and promotes its positive effects.
