带好“非全民”制员工队伍的几点思考

认同感、归属感是企业凝聚力的核心,责任感是企业发展的原动力。要使员工迅速、顺利地融入到整个团队中来,就一定要使员工对企业经营理念、发展目标、企业文化、管理制度、分配机制、所在的集体等都认同了,并自愿将自己的前途和命运与企业的发展紧紧联系在一起,与企业同呼吸、共命运,才有小到为集体近期目标的实现,大到为企业长远发展的思想。

Identity construction on Facebook: Digital empowerment in anchored relationships

Early research on online self-presentation mostly focused on identity constructions in anonymous online environments. Such studies found that individuals tended to engage in role-play games and anti-normative behaviors in the online world. More recent studies have examined identity performance in less anonymous online settings such as Internet dating sites and reported different findings. The present study investigates identity construction on Facebook, a newly emerged nonymous online environment. Based on content analysis of 63 Facebook accounts, we find that the identities produced in this nonymous environment differ from those constructed in the anonymous online environments previously reported. Facebook users predominantly claim their identities implicitly rather than explicitly; they “show rather than tell” and stress group and consumer identities over personally narrated ones. The characteristics of such identities are described and the implications of this finding are discussed.     

Multimodal Composition in a College ESL Class: New Tools, Traditional Norms

Research has noted that multimodal writing allows for better communication of knowledge and expression of personal identities through various modes of representation. Studies of multimodal composition have tended to examine separate modes, or have looked at connections between only a few selected available modes. Less attention has been devoted to multimodal composition from a holistic perspective. Drawing on the concept of synaesthetic semiosis [Kress, Gunther. (1998). Visual and verbal modes of representation in electronically mediated communication: The potentials of new forms of text. In Ilana Snyder (Ed.), Page to screen: Taking literacy into the electronic era (pp. 53-79). London: Routledge; Kress, Gunther, & Van Leeuwen, Theo. (2006). Reading images: The grammar of visual design (2nd ed.). New York: Routledge], the present study examines how ESL writers in a freshman composition class used available modes in multimodal argumentative essays posted on the World Wide Web. The findings indicate that word-dominated discourse was the primary factor in selecting available modes. Non-linguistic modes were primarily used to illustrate written essays. However, students also used non-linguistic modes to project cultural and national identities and to express emotional connections with their topics. The ways in which the students synthesized multiple meaning-making modes represented the social practices of learning multimodal genres in which they were engaged. The paper concludes with suggestions for pedagogy and research in multimodal composition.     

设计与身份认同

现代设计能够干扰身份认同形成的一个重要原因是现代人有着空前的身份认同需求,而设计所产生的物质文化恰能符合并满足人们的需求,成为建构身份的重要手段。设计作为一种推动力,优化、促进社会创新,在这个过程中,设计的干预有时是显现的有时是隐性的。其不可回避的两面性,更应审视对设计问题的揭蔽,我们无法选择设计与社会创新的必然关系,但我们可以在设计与创新这一永不间断的动态博弈过程中,使设计与社会创新生存的必然关系开展得更加符合人类终极目标和普遍利益。     

2014年索契冬季奥运会多面性视觉识别系统设计分析

本文作者多年来先后参与了北京奥运会、伦敦奥运会、巴西奥运会的设计指导工作,积累了大量形象系统设计的一手资料与实战经验,此次也参与了部分索契冬奥会特许设计的顾问工作。笔者站在系统设计的宏观角度,较为全面地介绍分析2014年索契冬季奥运会的视觉识别系统,包括会徽设计、核心图形设计以及火炬、服装、特许产品等推广衍生设计。分析提取形式背后所蕴含的设计方法,寻找暗合的国际设计潮流。最为重要的是,透过这套视觉识别系统可以看到最前沿的数字网络文化如何与丰富多彩的俄罗斯传统历史文化符号进行有效结合,这是完全不同于北京奥运会和伦敦奥运会的重要文本解读。     

互联网时代下城市空间品质提升与特色保护

In this interview, three scholars discussed the problems in China’s urban renewal practice in the Internet Era and the context of inventory development. They first reviewed the factors that impact the characteristics and identity of urban space, and pointed out that urban renewals should not neglect the social, cultural, artistic, historical, and ecological qualities of space. They then underscored the aesthetic education will be future research and practice interest in the field of urban renewal. They noted that, under the impact of “attention economy” and ”online influence,” urban spatial construction across Chinese cities would be homogenized, compromising the diversity of spatial characteristics. Nonetheless, urban planners and designers can leverage the online platforms as communication channels and resources for the protection of spatial characteristics and identities, and to foster new urban development paradigms. In addition, the scholars believed that the public should have a greater discourse power in urban renewals, which requires the the promotion of Community Co-building Initiative, and designers’ efforts in promoting related research and education programs. In the end, they discussed the challenges faced by the protection of historical sites, including the outdated urban governance methods, flawed urban development institution, and the lack of funds due to the slowdown of economic growth. They also encouraged designers to respond to these challenges with long-term, proactive, and innovative perspectives, truly meeting citizens’ daily needs, improving urban governance methods, optimizing urban renewal mechanisms, and impelling the growth of local economy.     

一种改进的基于ECC的免配对密钥协商协议

为了克服以往协议在密钥协商阶段易于受到各种攻击而导致会话密钥泄漏的缺点,提出了一种改进的基于ECC的免配对密钥协商协议,与传统的密钥协商协议相比在密钥协商阶段引入了身份验证令牌,使得窃听者无法窃取和篡改会话密钥,有效克服了以往协议容易受到攻击的弱点.分析表明,新协议与其他相关协议相比在保持较小的信息交换的前提下,使安全性有了很大的提高.     

Expressions of disciplinarity and individuality in a multimodal genre

Recent research has illuminated some of the ways in which multilingual writers project multiple identities in their writing, conveying disciplinary allegiances as well as more personal expressions of individuality. Such work has focused on the writers’ uses of various verbal expressions, but has to this point overlooked the ways in which they manipulate the visual mode as a means for identity expression. The present study examines expressions of identity in a corpus of multimodal texts written by four multilingual graduate student writers. I consider how the writers’ uses of various verbal and visual expressions in their Microsoft PowerPoint presentation slides project both disciplinarity and individuality and how each individual's habitus has been influenced by both the discourses they have encountered and their personal reactions towards those discourses.
