天地一体化信息网络中天基卫星网络架构设计

为了充分利用各种空间设施资源，提升天基信息网络覆盖与传输能力，分别从天基信息网络体系架构和逻辑功能架构角度进行了系统性设计。与以往天基网络的设计不同，该设计更注重各类卫星网络的深度融合应用，为此将网络虚拟化技术引入天基卫星网络。同时，还提出了解决新架构下卫星组网难题的方法，将电磁涡旋、卫星灵活载荷和边缘计算技术设计到天基网络。仿真表明，所提出的架构能有效提升频谱利用率和减少卫星网络信令开销。

Capital market trading volume: an overview and some preliminary conclusions

This paper suggests an explanation for the heavy trading volumeobserved on the US capital markets, the world's largest. Heterodoxeconomic theory puts much of this volume down to speculation.Mainstream theory tends to support this thesis, either directlyor indirectly, by giving space to the idea that trading activityis for the most part exogenous to the functioning of the capitalmarkets. The central hypothesis of this paper is that the tradingvolumes observed are an endogenous feature of the capital markets,because they are to a great extent determined by the needs ofthe institutional investors who predominate on these markets.This endogeneity of trading is posited in connection with theemergence of a new ‘core–satellite’ paradigmin institutional investment, a development that essentiallymanifests the asset-management industry's transformation froma small industry serving a few wealthy clients to a mass industryserving large sections of the population.

长江干流地区跨世纪交通运输网络建设的总体构想

长江干流地区自宜宾至上海长约２８００ｋｍ，横跨中国东、中、西三大经济地带，面积占全国４．３％，有十分重要的战略意义。今后这一区域路网建设的目标是建成以长江干线为主轴，以宜宾、重庆、万县、枝城、武汉、丸江、芜湖、南京、江阴为结点的＂九纵一横＂的路网格局。长江干线包括加深长江航道，建设沿江铁路和沿江高等级公路。同时加强纵向铁路、公路和水运干线建设，形成若干水陆交通枢纽，并加强干线和支线机场建设，在上海、南京、武汉、重庆建成国际航空港。     

Online brand community within the integrated marketing communication system: When chocolate becomes seductive like a person

This study proposes brand communities as an effective tool within the integrated marketing communication (IMC) system. The paper utilizes the Brand Concept Map quali-quantitative technique in order to represent and compare mental association texture within one group of non-members of a brand community versus one group of people engaged in the same community. Brand stimulus is Nutella (chocolate cream) which boasts a crowded and lively online brand community: Nutellaville. Results show that brand community is effective in terms of contribution, commonality, and complementarity within the IMC system. In particular, Nutella brand image within the online community participants is composed of some mental associations overlapping other communication tools (commonality), and by new mental associations (complementarity) referred to the brand image dimension named ‘brand as person’ (seductive, popular, reassuring); second, this anthropomorphism effect solves the issue of sense of guilt excited by chocolate (contribution).     

Tradespace exploration of in-space communications network architectures

Making architectural decisions in long lifecycle systems is challenging because the time between system definition and end of operations can span multiple decades, resulting in shifts in stakeholder needs and major advances in technologies. Space-based communications using relay satellite constellations is one such example, requiring substantial up-front planning to define capabilities and size capacity due to the large investment of time and resources. Additionally, there are numerous viable system architectures. In this paper, we build on existing methods to develop a graph-based decision method to assess and explore architectural flexibility in the future evolution of long lifecycle systems. The tradespace graph defines edges between similar architectures, quantifies the switching cost between architectures, using graphs to analyse the potential system evolution pathways. In a test case on NASA communication satellites, we find that hosting government communications payloads, in particular optical payloads, on commercial satellites could reduce cost and increase flexibility of the NASA network.     

Effects of personification and anthropomorphic tendency on destination attitude and travel intentions

This research examined how individual differences in anthropomorphic tendency (the tendency to humanize non-human agents/objects) influence how people respond to destination marketing communications. Specifically, this study examined whether individual-level anthropomorphic tendency and text-personification of destination marketing communications interact to influence destination attitude and travel intentions. Results from a study involving 210 Australian participants revealed that destination attitude and travel intentions were most favorable for people with high levels of anthropomorphic tendency and who were exposed to personified tourism messages. These findings indicate that text-personification represents a new communication tactic for tourism – particularly for target consumers who are high in anthropomorphic tendency – and one that can humanize the destination leading to more favorable attitudes and higher intentions to travel. This effect is mediated by positive emotions. People with high anthropomorphic tendency who are exposed to a personified advertisement feel more positive emotions, which lead to positive tourism outcomes.     

The Corporate Side of the Blogosphere: Examining the Variations of Design and Engagement Among Fortune 500 Blogs

Using design and communication principles, this study uses a content analysis design to evaluate all active blogs from the 2011 Fortune 500 list (n = 125). The results indicate that corporate America has only modestly incorporated the dialogic principles into their blogs. Current corporate blogs are well-designed as far as making them searchable and easy to navigate; however, the blogs are mostly being used to provide information in a one-way manner rather than creating an open dialogue with consumers. While blogging can enhance relationships with stakeholders, corporate communicators must strive to develop legitimate conversations with their blog readers.     

Exploring effects of source similarity,message valence,and receiver regulatory focus on yelp review persuasiveness and purchase intentions

This study is among the first to investigate the impact of message, source, and receiver characteristics on user attitudes toward Yelp reviews, with the subsequent impact of these attitudinal evaluations on review persuasiveness. Specifically, it examines the roles of review valence (positive/negative) and sidedness (one-sided/two-sided), as well as perceived similarity with the reviewer, on user perceptions of helpfulness, trustworthiness, and credibility of the review. The study also tests moderating effects of perceived source similarity and user regulatory focus on the relationships among message characteristics, attitudinal variables, and purchase intentions. Our results disconfirm the negativity bias reported in previous studies and indicate that positive reviews are perceived as more trustworthy, credible, and helpful than negative or two-sided reviews. Review helpfulness and credibility, in turn, positively impacts its persuasiveness, with regulatory focus playing a complex nuanced role in the persuasiveness – behavioral intentions relationship. Based on the findings, future research avenues and managerial implications are proposed.
