基于扩散张量的图像混合去噪方法

图像去噪过程中,主要目的是有效去除噪声的同时能较好地保存图像的边缘与细节。基于此,本文根据自蛇模型与相干增强扩散的特征,提出了相应的混合去噪方法,并加入了保真项。实验结果表明该方法能有效去除图像噪声,同时对边缘信息的保留也较好。     

一种改进的非凸秩最小化算法及其在矩阵恢复中的应用

在分析现有处理矩阵恢复问题的非凸秩最小化算法的基础上,提出了一种基于超松弛迭代的改进算法,并给出了松弛因子ω的确定准则。仿真实验表明:在惩罚参数选取较大的情形下,改进算法较原算法具有更快的收敛速度及更高的收敛精度,同时展示了基于非凸秩最小化算法的矩阵恢复技术在图像去噪中的应用。     

环境意识与企业形象塑造

可持续发展的思想和社会市场营销观念已成潮流。为适应市场需求的变化和环境管理的要求,寻 求市场机会和避免环境威胁,必然要求企业树立环境意识,履行应尽的社会责任,并融入、体现在企业 形象塑造中。在企业识别系统中贯穿“环境形象”设计是企业形象塑造的关键。     

分块自适应图像稀疏分解

针对图像稀疏分解的计算时间复杂度非常高这个问题，提出了分块自适应图像稀疏分解算法。该算法根据稀疏分解计算时间复杂度和待分解图像大小之间的关系。把待分解图像分成互不重叠的小块。然后对每个小块图像进行稀疏分解。根据每一块的复杂程度。自适应地决定稀疏分解的结束。实验结果表明。在分解原子个数相近或相同的条件下。新算法对稀疏分解后重建图像比在整幅图像上进行稀疏分解重建的图像质量下降0．5dB。但计算速度提高了约15倍。     

消费者对大型超市的商店印象与其忠诚行为关系实证研究

商店印象对消费者购物行为有重要的影响。本文在我们先前对商店印象与顾客忠诚关系研究的基础上,将商店印象与顾客忠诚的构面展开,进一步研究了商店印象的实体、经济、时间与便利性和社会心理构面与顾客认知忠诚、情感忠诚、意向忠诚和行为忠诚之间的关系,并通过在全国收集的803份有效样本,运用结构方程模型对理论模型进行了实证检验,全面揭示了商店印象各构面与四类顾客忠诚之间的关系。     

品牌形象对消费者行为倾向影响的实证研究

本文认为,品牌形象影响并决定着人们的购买和消费行为,独特的品牌形象可以帮助企业确立品牌定位,阻止品牌竞争,改善品牌的市场表现。品牌形象由品牌表现、品牌个性、公司形象三个维度构成,三者不存在层级关系。其中,品牌表现是影响消费者行为倾向的主要因素;品牌个性影响消费者行为倾向,但影响程度较弱;公司形象通过品牌表现和品牌个性间接影响消费者行为倾向,对消费者行为倾向无显著影响。文章提出,企业可以通过三种品牌形象进行品牌定位,即品牌功能属性定位、品牌个性定位、公司形象定位,品牌形象管理即企业进行品牌定位的过程。对于中国企业来讲,品牌个性和公司形象的定位更值得关注。开发独特的品牌形象,建立吸引人的差异化的品牌形象的品牌战略,加强企业品牌形象的推广,是提高顾客忠诚度的根本途径。     

Assessing the Effects of Service Quality,Past Experience,and Destination Image on Behavioral Intentions in the Spring Training Camp of a Japanese Professional Baseball Team

This study aimed to examine the theoretical relationships between service quality, past experience, destination image, and behavioral intentions in the spring training camp of a professional baseball team in Japan. The results indicate that the service quality of spring training camps was divided into five factors: (1) place, (2) enjoyment, (3) information, (4) fan interaction, and (5) operating time. The findings suggest that service quality and past experience had positive effects on both destination image and behavioral intentions. Behavioral intentions were also highly influenced by destination image. Future research and managerial implications are also discussed.     

The Role of Place Image Dimensions in Residents' Support for Tourism Development

Understanding residents' perceptions of tourism impacts and their level of support for its development is considered vital for the sustainable development of tourism. Despite the plethora of factors examined as determinants of residents' attitudes toward tourism, the role of residents' place image has been under‐examined. This study developed a model examining the relationships between residents' place image dimensions, perceived tourism impacts and support for development. Findings suggest that two (physical appearance, social environment) out of the four place image dimensions identified in this study exercise a significant effect on residents' attitudes toward tourism. The theoretical and practical implications to the formation of planning and development programs for tourism are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

‘Does it Really Affect Me?’ Tourism Destination Narratives,Destination Image,and the Intention to Visit: Examining the Moderating Effect of Narrative Transportation

The extent to which tourism destination marketing narratives with different themes influence readers by imaginatively ‘transporting’ them is quite varied. This study investigates the different degrees of influence such narratives have on destination image and the intention to visit, exploring how the intensity of readers' experiences of being transported by narratives with different themes can influence their intention to visit the places described. Our results reveal the extent to which different narrative themes affect destination image and significantly influence readers' intention to visit. The extent to which narratives with different themes make readers feel transported also has a significant moderating effect on their intention to visit. Copyright © 2015 John Wiley & Sons, Ltd.     

“国际金融中心”需要怎样的城市形象广告片?——上海城市形象广告片的受众认知和态度比较研究

上海立志建设成为国际金融中心,打造这一城市品牌形象是一个系统工程,营销传播工作是重要的组成。本研究从广告效果空间论角度,对上海现有的四部城市形象广告进行了受众认知和态度效果的比较,并引入中外受众所代表的不同涉入度作为调节变量。我们根据结果绘制了四支广告在认知-态度二维图上的位置,并发现不同涉入度对认知效果没有调节作用,而对态度效果上则有调节作用。基于这些发现,我们提出了如何创作有效的国际金融中心城市形象广告的建议。
