城市品牌定位的视角探析

城市品牌的定位,就是对城市现有形象及未来发展远景的描绘,是经营城市、建立城市品牌的核心问题。实施品牌化战略需要厘清城市品牌定位视角的若干原则。在遵循原则的基础上可从区位特征、特色资源、竞争优势、支柱产业、历史文脉、政策引导等几个视角进行城市品牌定位。     

晶闸管改进型桥式变流器的双重化研究

提出具有功率因数改善的改进型桥式变流器的一种双重化方案，对其换流过程和工作情况进行了分析，导出了数学模型及保证安全换流的最小逆变角，并与通常的12脉波桥式变流器进行了比较．     

《蝴蝶梦》叙事视角解读

完全按照内聚焦型视角叙述作品的《蝴蝶梦》展示给我们的是一段贵族白马王子与灰姑娘的爱情故事。作者选择这种叙事视角一方面是为了表达一种"人是平等的"命题,寄寓一种"纯粹是灵魂呼应灵魂的爱情"理想,另一方面,因了"爱情障碍"的设置和排解,使叙述者"完全被戏剧化"了。由此看来,达夫妮·杜穆里埃将叙事视角定位在內聚焦型上,使整部小说成了主人公的戏剧独白,这样把叙事话语、非叙事话语融入人物话语之中,把感知视角和认知视角紧密结合起来,使小说语言独具特色,其小说叙事方式上的革新意义凸现。     

关键事件技术及其应用——以制造商转换行为的研究为例

作为一种定性研究方法,关键事件技术特别适用于理论发展和管理有效性等研究目的。目前,该方法被广泛应用于教育、管理、零售、服务接触以及关系管理等领域进行探索性研究,其信度和效度也一再得到检验和证明。本文首先介绍了关键事件技术,并将其运用到制造商转换行为的研究之中。研究表明:价格、产品质量、物流能力、公司采购战略、服务质量是影响制造商转换的最为重要的原因。而且,不同的转换原因对制造商的满意度有不同的影响。在进一步分析的基础上,本文还得出85%的制造商转换属于复杂转换以及关系对顾客保留的影响可能与供应商所能提供的顾客价值有关等等富有意义的结论。     

震后早期心理辅导探讨

5·12汶川大地震后,心理援助的重要性受到前所未有的关注.震后人们会出现不同程度的心理应激反应,相当比例的人会出现心理应激障碍.针对这些问题应进行适当的早期心理辅导.早期心理辅导应以创伤后危机干预为思路,以缓解应激障碍相关症状、预防创伤后危机障碍的发生为主要目标,采取心理急救、严重事件应激晤谈、认知行为疗法等方法进行治疗.另外,从这些方法中可归纳出共同的、可用于早期心理辅导的原则:支持性原则、正常化原则、重视社会支持原则、个性化原则等.     

Critical Infrastructure Vulnerability to Spatially Localized Failures with Applications to Chinese Railway System

This article studies a general type of initiating events in critical infrastructures, called spatially localized failures (SLFs), which are defined as the failure of a set of infrastructure components distributed in a spatially localized area due to damage sustained, while other components outside the area do not directly fail. These failures can be regarded as a special type of intentional attack, such as bomb or explosive assault, or a generalized modeling of the impact of localized natural hazards on large‐scale systems. This article introduces three SLFs models: node centered SLFs, district‐based SLFs, and circle‐shaped SLFs, and proposes a SLFs‐induced vulnerability analysis method from three aspects: identification of critical locations, comparisons of infrastructure vulnerability to random failures, topologically localized failures and SLFs, and quantification of infrastructure information value. The proposed SLFs‐induced vulnerability analysis method is finally applied to the Chinese railway system and can be also easily adapted to analyze other critical infrastructures for valuable protection suggestions.     

Freire's Conscientization, Dialogue, And Liberation: Personal Reflections on Classroom Discussions of Marginality

Using Freire's notions of conscientization, dialogue, and liberation, the author reflects on how he has engaged a student-centered dialogue in his teaching in general and in discussions of sexism, heterosexism, homophobia, and transphobia in particular. More specifically, he examines how this dialogic process enables his students and himself to (re)discover ways in which they can liberate themselves by exposing normalizing discourses and dominant ideologies, examining the relationship between oppressor and oppressed, shifting from object to subject positions, and (re)negotiating power relations.     

《世说新语》研究与魏晋文学史的"原生态"视角

文学史研究中一直存在着这样的尴尬:"史"的序列性、规定性解释系统反过来会破坏作品原初存在的"活性"成分.为此,我们不得不用"原生态"的理论来回溯作品的历史情境,以期减少必定存在的文学性的散失.《世说新语》之与魏晋文学研究,恰是一个难得的"原生态"视角.     

Paulo Freire in the Composition Classroom

The composition classroom in which students can relate and assess their attitudes and suppositions about sexuality and gender through building on the narrative of their lives, is vital to transforming homophobic attitudes and social structures. Paulo Freire's theories of transformative education and his concept ofpraxishelp to create this classroom. The author discusses how she createspraxisin her classrooms, which she believes is essential to social, legal, and political change: to consolidating and expanding increased equity for lesbian, gay, bisexual, and transgender people, indeed to all marginalized peoples.     

论德里达对马克思的另一种阅读

在苏东剧变、社会主义遭遇挫折的世纪之交,德里迭出版了<马克思的幽灵>一书,郑重提出要维护"马克思的幽灵",即维护一种马克思主义的批判精神.德里达对马克思文本的重新解读不是要回到传统的马克思,而是要借"马克思的幽灵"来建构一种解构的马克思主义,以在全球化语境中祛除.新国际"话语的"宏伟叙事",呼吁异质性.
