含硼聚硅铝的形貌结构研究

向聚硅酸中引入Al3+、B,制得稳定性更好的高效絮凝剂含硼聚硅铝(PASB)。用电子显微镜观察分析了PASB的形貌,用红外光谱和X-射线研究了其中B、铝离子及其水解产物与聚硅酸的相互作用情况,并对其电学特征进行了考察。结果表明B、铝离子及其水解产物和聚硅酸等多种组分之间有相互作用,形成了尺度更大的聚集单元。PASB的这种特殊结构是其具有良好稳定性和混凝性能的根本原因。     

艺术节与城市——西方艺术节的理论与实践

1980年代以来,全球范围内艺术节层出不穷,并在城市的发展中扮演着日益重要的角色。在此背景下,立足西方艺术节的理论与实践,全面分析与总结艺术节对城市的综合影响:①艺术节对城市形象的影响,包括内部文化氛围及其外部国际化形象,以及城市的文化软实力;②艺术节对城市经济的影响,包括宏观层面对城市经济转型的引导与催化,以及微观层面不同类别的经济收益。这些理论与实践对于我国艺术节的科学运作和可持续发展具有重要的借鉴意义。     

秉持“两型社会”理念传播城市形象——以长株潭城市群为例

近年来,随着中国经济的快速发展及其国际地位的不断提高,我国地方政府已经有了越来越强的城市形象意识,各种形式的对外传播活动也相继展开。但是,对中国城市而言,城市形象传播毕竟是一个全新的实践领域,许多规律性的东西我们还没有把握好,一些观念与思路也没有调整到位,这在很大程度上影响着我国城市形象塑造与传播的效果。为此,我们借助地理传播学以长株潭城市群作为样本,利用网络数据库建立组合矩阵模型进行量化分析认为,长株潭秉持"两型社会"理念传播城市形象的成功做法和经验颇值得借鉴。     

建国以来中国国家形象建设的历史演变及启示

随着全球化进程加速演变和中国改革开放事业不断推进,中国的国家形象建设问题日益引起关注。梳理和总结建国60年来中国国家形象建设历程和经验,加深对国家形象建设规律的认识和把握,对于在新的历史起点上推进国家形象的建设具有十分重要的作用。新时期中国国家形象建设应具有新的思路,需要转变观念,调整战略,要讲究传播策略,提升塑造效果。     

旅游者认知地图研究综述

认知地图是行为地理学中的一个重要研究领域,本文在梳理认知地图的概念体系、地理学与心理学对认知地图研究基础上,综述了近30年国内外旅游者认知地图的研究.研究发现:①旅游者认知地图是具有空间定位功能的、动态的、三维的旅游环境综合表象;②受旅游活动特点和旅游地类型影响的旅游者形成了独特的认知地图类型与空间结构;③旅游者在环境习得速度和过程方面都与一般环境学习存在显著差异;④旅游者认知地图形成过程中的人类影响因素主要表现为游客类型影响因素;⑤旅游领域的研究多采用适合现场情境的方法和技术;⑥旅游者认知地图研究尚处于不成熟阶段,主要表现为研究思想、内容和方法技术等方面的缺陷.最后提出旅游者认知地图几个多学科的重要命题.旅游者认知地图研究对于旅游规划、旅游目的地营销和旅游空间行为研究具有一定理论和实践意义.     

The impact of perceived security and consumer innovativeness on e-loyalty in online travel shopping

ABSTRACT

This study investigates the impacts of perceived security and consumer innovativeness on online travel shopping. A survey questionnaire was used to collect data and a total of 283 questionnaires were used for data analysis. The mechanism of perceived security and consumer innovativeness was then identified. The study results indicate that: (1) higher perceived security increases the perception of website image and trust; (2) consumers with a higher level of innovativeness tend to trust travel websites; (3) website image has a mediating effect between perceived security and trust; and (4) trust has a mediating effect between website image and e-loyalty.     

‘I just hope people can forgive me’: Australian women athletes,apologies and image restoration at the Rio Olympic Games

Prior to the 2016 Olympic Games, Australia’s Chef de Mission Kitty Chiller predicted that the Australian team could win as many as 16 Olympic gold medals. Australia’s Olympic team won a total of eight gold medals and the sports media reacted by suggesting the team had ‘failed’. At the 2016 Olympic Games, three high-profile Australian female athletes apologised to the Australian public for their performances. This study examines these three interconnecting cases and how such behaviour is linked to research that examines sports media and gender (including female agency), ‘image restoration’ and third-wave feminism. Additionally, this work identifies how the culture of third-wave feminism is conceptually troubled by the notion of the ‘female apologetic’ and calls for a re-examination and modification of such a notion.

Factors influencing repeat visits to a destination: The influence of group composition

This paper is an analysis of the likelihood for repeat visits to a sun and sand destination by tourists. For this purpose, an empirical study was conducted using tourists who had visited the destination. The analysis took into account the travelling group composition. The results showed that, for the total tourist sample, overall satisfaction had the biggest influence on the decision of whether to revisit a destination, while the least important influence was the tourist's perceived image. These influences varied, however, when different travelling group compositions were considered. The results are of vital importance in tourism management policies, because they can contribute to the better design and development of tourism promotion strategies.
