兼容二元:中国县镇乡发展的基本判断与路径选择

新型城镇化的国家战略对于县、镇、乡是一次新的发展机遇。通过更大数量和更基层的县城、镇等的发展,将城市资本与数量众多的县、镇、乡的土地、劳动力等资源集合起来,能够进一步生产和扩大市场,维持社会稳定。结合城乡关系过程的政治经济分析和历史讨论,作者提出县镇乡"兼容二元"的发展路径。但县、镇、乡的发展不仅仅与市场有关,它们的发展也不仅仅是被整合入全球经济生产链的问题。它们的开放或内生性发展对于地方的文化发展、大地景观、生活方式与价值理念、环境状况等都将有巨大影响,这仍然需要进一步讨论。     

The function of self-disclosure on social network sites: Not only intimate,but also positive and entertaining self-disclosures increase the feeling of connection

How can social network sites (SNS) foster relationships when most status updates on SNS are mainly entertaining and not very intimate? This finding cannot be explained by classical social psychological theories such as social penetration theory which regard disclosure intimacy as the main driver of relational outcomes. By building on literature on the role of capitalization and humor in relationship formation and maintenance, this paper suggests two alternative paths from public self-disclosure to relational outcomes. Respondents judged the content and relational effects of own and friends’ status updates as well as private conversations. In general, all types of messages were mainly positive and entertaining. The more intimate communication took place in private conversations; here, the classical link between disclosure intimacy and feeling connected still held. However, positive and entertaining self-disclosures also increased the feeling of connection, especially when reading friends’ updates. Interestingly, interaction partners’ responsiveness did not play a significant role, indicating that results from dyadic face-to-face interactions do not hold for public communication on social media. The study contributes to the development of a more differentiated model on the role of self-disclosure on SNS.     

Looking at both sides of relationship dynamics in virtual communities: A social exchange theoretical lens

This study draws on social exchange theory to investigate the relationship dynamics of the member–community dyad in virtual community settings. Using a longitudinal design and multiple measurement sources, the findings indicate that social and task communication styles have unique effects on members’ community commitment velocity, which in turn influences member gratitude and entitlement behaviors. A moderated path analysis demonstrates that the effects of social and task communication styles on community commitment velocity are both positively moderated by attachment anxiety and attachment avoidance. It also reveals that members’ level of popularity augments the influence of community commitment velocity on member entitlement behavior.

建筑文化关联──中国传统建筑文化内涵

建筑是一种文化载体。纵观建筑历史长河,各个历史阶段的建筑都是作为一种文化现象深深地沉积下来。这些文化现象包括科学、艺术、宗教、道德、法律、风俗、习惯等等。它们都是人类物质与精神财富的沉淀,具有历史的延续性,同时反映着民族文化特征。本文从中国建筑伦理文化对空间组织的影响及中国传统建筑装饰两方面进行了论述。

Key relationship-based determinants of project performance in China

The aim of this paper is to investigate the relationship-based factors that affect performance of general building projects in China. Thirteen performance metrics that may be used to measure the success level of construction projects are defined and categorized into four groups namely cost, schedule, quality and relationship performance. Fourteen risks inherent in relationships and 16 tools expected to facilitate relationship building that may affect project success are identified. Data of different projects were collected in China via a self-administered postal survey. Multiple linear regression models are developed to help explain the variance in different performance metrics. It has been found that ten risks and nine tools have either positive or negative influence on project performance to some different extents and in different project development process stages. Detailed explanations are made, especially to those variables bearing unexpected signs. It is recommended that firms in the Chinese construction industry manage the relationship-based factors that are significant in the MLR models so as to achieve project success.

一种稀缺的力量 ——擅长对话的创造型结构工程师张准访谈后记

建筑师与结构工程师的合作是建筑作品创新的一种重要途径。建筑学与结构工程的细分带来建筑师与结构工程师多样的共事关系,影响建筑作品创新的角度。能够与建筑师展开对话、共同探讨创作的结构工程师,是创造型建筑师渴望合作的稀缺力量。作为擅长对话的结构工程师张准的访谈后记,本文尝试从一个侧面为期望转型的传统结构工程师提供一些成长的参考,为渴望对话的建筑师提供一些策略的参考。     

Identifying the critical success factors for relationship management in PPP projects

The longer the contract period, the higher the chance that major changes will arise. Thus a greater reliance on the established relationships is needed to maintain the contractual bond in PPP project. Relationship management (RM) can therefore be expected to be even more valuable in the PPP context. This paper aims to investigate current perceptions and experiences of RM in PPP projects and more importantly, to identify the CSFs for RM in PPP projects. By means of an empirical questionnaire survey geared towards PPP practitioners with direct hands-on experience, the opinions were solicited, analyzed and compared in relation to potential PPP RM success factors. The survey findings indicate that industry practitioners currently lack a general understanding of concepts and applications of RM, given that it is relatively new in PPP. However, they do think that RM is very important to improve the present performance of PPPs. Future PPP business opportunities can also be increased by effective RM. The top four CSFs for RM are found to be commitment of senior executives, defining the objectives, integration of the different divisions and a multidisciplinary team. However, the relative importance presently assigned for each of the above factors is insufficient, and commitment from senior management is perceived as the most difficult factor to improve.
