北京旅游目的地形象的感知——中西方旅游者博客的多维话语分析

目前,很少有学者采用旅游者博客这一新兴的方式研究游客对旅游目的地形象的感知。文章选择中西方旅游者博客话语为切入点,从“文化繁荣”、“宜居和生态”、“现代化大都市”、“社会和谐”和“经济发展”5个维度探讨中西方游客对北京旅游目的地形象感知的异同,并讨论了两个不同旅游群体在文化背景、意识形态和消费水平方面的差异。最后,文章对如何提升来京中西方游客的体验评价提出了切实的建议。此研究意在强调旅游者博客在旅游目的地形象研究中的重要意义,同时亦希望能够对话语分析的跨学科发展作出贡献。     

国家形象与目的地形象：概念的异同和整合的可能

国家形象是国际商务和国际营销领域的重要概念,目的地形象是旅游领域的重要概念。在竞争日益激烈的全球化市场上,国家形象和目的地形象对于产品和旅游目的地获得竞争优势具有重要的战略价值。目前,国家形象和目的地形象研究基本上是独立的,文章在全面回顾两个领域最新研究进展的基础上,分析两概念定义、理论基础、形象主体和客体、形象内容等方面的异同;根据对国家形象、目的地形象与旅游研究中的其他社会心理变量之间关系的分析,提出整合这些变量的旅游意向模型以及相应的三个命题,以引导下一步的实证研究。     

基于CenterNet的跑步姿态鉴别系统的设计

为了改善目前大众跑步姿势普遍不规范的现状,提出了一种基于CenterNet的跑步姿态鉴别系统。首先,通过截图、拍照的方式自制数据集,并对数据集进行清洗、标注和分析,消除数据无关信息与简化数据。其次,引入多尺度通道注意力机制与添加十字星变形卷积2种方式改进CenterNet算法模型,将动作图像转化为数字信息和特征向量,并以此为基础,利用KNN（K-nearest neighbors）算法对跑步姿态类型进行分类。最后,与经典模型方案进行对比,验证改进CenterNet算法鉴别系统的有效性。结果表明：改进的CenterNet模型的精确率与召回率都有所提升,其参数量与计算量降低。所提算法模型能够对大多数不良姿势作出及时、准确反馈,有效帮助跑步爱好者发现问题,从而改善跑步姿态、提高运动效率、预防伤病。     

零售品牌形象构成要素实证研究

良好的品牌形象可以降低消费者购物过程中感知的风险,从而提高其满意度和忠诚度,作为一种独特的竞争优势,它又可以使企业获得强大的品牌资产,并为品牌延伸提供了依据.笔者试图通过问卷调查,从消费者的视角识别出零售品牌形象的主要构成要素.研究发现,零售品牌形象是一个多维的概念,它主要由31个指标构成并可以划分为7个纬度.与国际零售品牌相比,本土零售品牌的名称更容易为消费者记忆与传播,消费者对本土零售品牌名称的认知明显高于国际零售品牌.

Methodology Influences on Destination Image: The Case of Michigan

In the last 30 years, destination image has emerged as a dominant theme in tourism research studies for both tourism industry practitioners and academic researchers. The results of these studies are intended for destination management purposes and thus are of utmost importance for destination success. Various factors are postulated and demonstrated to influence destination image; however, there is a lack of focus on the methodologies employed when evaluating the image of a destination. The purpose of this study is to investigate the potential impact of some methodological tools used when measuring destination image. A large scale and longitudinal market survey dataset of the Michigan Regional Travel Market Survey was analysed for the purpose of this study. A wide range of methodological factors from data gathering modes to analytical techniques utilised were found to influence the revealed image of the study destination, Michigan. Detailed discussion of potential bias factors and potential research directions are provided.     

Analyzing Destination Images: A Perceptual Charting Approach

Abstract

Heterogeneity of perceptions is a neglected issue in market segmentation studies. Only recently parametric approaches toward modeling segmented perception-preference structures such as combined MDS and Latent Class procedures have been introduced. A completely different nonparametric method is based on topology-sensitive vector quantization (VQ) for consumers-by-brands-by-attributes data. It maps the segment-specific perceptual structures into bar charts with multiple brand positions exhibiting perceptual distinctiveness or similarity. A brief introduction into the VQ methodology is followed by a sample study on three urban destinations competing on the world travel markets. City images serve as the underlying behavioral constructs. Preferential data are based on respondents' comes-closest-to-ideal-city judgments and incorporated into the perceptual positions of city profiles. Perceptual charting works on two levels of aggregation named prototypes and perceptual sub-structures. The results demonstrate how this method prevents the analyst from drawing erroneous conclusions due to uncontrolled aggregation.     

Effects of Negative Brand Information: Measuring Impact of Celebrity Identification and Brand Commitment

ABSTRACT

This study investigates the relationship between negative brand publicity and a celebrity endorser. First, it explores whether identification with a celebrity moderates the relationship between negative brand publicity and evaluation of a celebrity endorser and a brand. Second, it delves into whether consumers’ brand commitment moderates the relationship between negative brand publicity and evaluation of a celebrity endorser and a brand. And the study poses the research question, “Does negative brand information impact consumer evaluation of a celebrity endorser, a brand, and purchase intention?” A 2 × 2 between-subject factorial design was used to test the proposed hypotheses. The two factors are level of identification with a celebrity endorser (low or high identification) and level of brand commitment (low vs. high brand commitment). The study found that negative brand publicity had negative impacts on the celebrity endorser, brand evaluation, and purchase intention.     

The effect of human image in B2C website design: an eye-tracking study

On B2C shopping websites, effective visual designs can bring about consumers’ positive emotional experience. From this perspective, this article developed a research model to explore the impact of human image as a visual element on consumers’ online shopping emotions and subsequent attitudes towards websites. This study conducted an eye-tracking experiment to collect both eye movement data and questionnaire data to test the research model. Questionnaire data analysis showed that product pictures combined with human image induced positive emotions among participants, thus promoting their attitudes towards online shopping websites. Specifically, product pictures with human image first produced higher levels of image appeal and perceived social presence, thus stimulating higher levels of enjoyment and subsequent positive attitudes towards the websites. Moreover, a moderating effect of product type was demonstrated on the relationship between the presence of human image and the level of image appeal. Specifically, human image significantly increased the level of image appeal when integrated in entertainment product pictures while this relationship was not significant in terms of utilitarian products. Eye-tracking data analysis further supported these results and provided plausible explanations. The presence of human image significantly increased the pupil size of participants regardless of product types. For entertainment products, participants paid more attention to product pictures integrated with human image whereas for utilitarian products more attention was paid to functional information of products than to product pictures no matter whether or not integrated with human image.     

What induces online loyalty? Online versus offline brand images

This study investigates the effect of the interplay between a multi-channel retailer's offline and online brand images on consumers' online perceived risk and online loyalty within the framework of a theory of cognitive dissonance. A sample of 671 female college students participated in an experiment using a 2 (prior offline brand image) × 2 (online performance) between-subjects design. Results reveal that offline brand image exerts significant effects on online brand image - which, in turn, significantly explains online perceived risk - and online customer loyalty. However, online perceived risk has no significant effect on online customer loyalty after controlling for the effects of online and offline brand images. These results provide implications for the direct and indirect halo effects of offline brand image and the direct effect of online performance that may influence consumers' perceptions, expectations, and loyalty regarding multi-channel retailers.
