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.     

Google Earth在成都市功能分区研究中的应用

在历经了20余年的改革发展后,成都市在基础设施建设、产业结构调整和生态环境保护等方面都取得了长足的进步,在政治经济文化发展的同时,城市的用地规模日益扩大,城市功能分区日趋复杂,人地矛盾、功能与形态分区矛盾日渐凸现,城市功能分区已经成为制约城市发展的重要因素之一.为此开展成都市功能分区的研究也愈加重要,利用Google Earth软件提供的在线浏览的高分辨率遥感图像,结合其特有的空间分析和查询功能,探讨成都市的功能区的分区及成因,并对城市功能分区的发展趋势做出预测.     

基于优化HRNetV2的高分辨率遥感影像土地利用自动分类

研究目的：基于语义分割模型HRNetV2实现高分辨率遥感影像的土地利用自动分类,以期推动深度学习语义分割方法实现遥感影像的土地利用自动分类研究,并为该类研究提供可参考的案例。研究方法：首先对语义分割模型HRNetV2从损失函数、特征提取方面进行优化,以提高模型的分割精度;其次用优化后的HRNetV2模型对民乐县2 m的高分辨率遥感影像进行土地利用分类,并基于混淆矩阵对分类的结果进行评估。研究结果：（1）优化后的HRNetV2语义分割模型的MIOU达81.9%,相较于优化前提高了4.4%, 证明了优化方法的有效性;（2）针对民乐县进行的土地利用自动分类总体精度达89.72%,Kappa系数达0.888。研究结论：优化后的HRNetV2语义分割模型在高分辨率遥感影像的土地利用自动分类中具有较强的应用前景。     

菲涅耳非相干全息术3D全息成像探讨

全息成像提供了一种从单一观察点捕捉具有完整三维信息画面的可靠、快捷的方法。本文回顾了近期提出的单通道菲涅耳数字全息光学系统,该系统能获得由非相干光照射的三维实物体的全息图。在这一静态全息技术中,由三维物体反射或发射光,在通过空间光调制器（SLM）后,用数码相机记录。SLM被用作单通道非相干干涉仪的分束器,使来自物体上各点的球面波被分成两束具有不同曲率半径的球面波。所有球面波干涉结果的非相干总和,即可生成被观测物体的三维菲涅耳全息图。在计算机中可再现该全息图,使其三维特征得以呈现。     

基于形象视角的品牌转型策略

当前情境下,本土企业进行品牌转型已成必然趋势。品牌管理的本质在于对存在于消费者心智中的品牌形象进行管理,因而从形象视角进行品牌管理是品牌转型的有效途径。基于形象视角的管理理念,企业品牌转型应该采取转变经营理念、建立专业品牌管理团队、建立形象管理系统、重视消费者沟通等策略。     

一种基于Levy-人工蜂群的三维Otsu阈值分割算法

针对图像分割过程中三维Otsu算法运算时间长、计算量大的问题,提出了一种基于Levy-人工蜂群算法的三维Otsu阈值分割算法。首先,以像素灰度值-邻域均值-邻域中值的三维类间方差作为人工蜂群算法的适应度函数;其次,采用Levy飞行模式评价像素的适应度,对其种群更新及邻域搜索过程进行优化,以增强其全局搜索能力;最后,利用改进后的算法得到的分割阈值对图像进行分割。仿真实验结果表明,与传统三维Otsu阈值分割算法相比,所提算法能够有效降低图像存储空间,处理时间降低了30.8%,具备更好的抗噪性能,分割效果也更为理想。     

一种新的快速视频图像边缘检测算法

一般常用的边缘检测算法计算量较大，对细小边缘检测效果较差，不适合实时边缘检测系统。针对这一问题，本文提出一种连续分割的快速边缘检测算法：从相互垂直两方向分割梯度图像，提取截面曲线极大值获得图像边缘，使用形态学梯度，检测出细小的图像边缘。实验结果表明此算法较Canny等经典算法减少了计算量，提高了边缘检测精度。     

Tourism Brochures: Usefulness and Image

Tourist information has been shown to have an important influence on the choice of vacation destinations. This article studies brochures, their significance as image generators, and their influence on the selection of destinations. The study sought to discover which features in this medium are more relevant in image generation and destination choice using logistic regression analysis. The analysis is based on data collected from tourists in Madrid, Spain. The results establish a model of usefulness of brochures in order to propose recommendations for their design and content. Implications pertain to the development of theoretical understandings about the influence of the information sources on destination image, destination choice, and satisfying tourist needs.     

Entrepreneurs: Invent a new brand name or revive an old one?

This paper discusses launching an entrepreneurial venture by acquiring a once popular brand name and reviving it. Interviews were conducted with 10 executives who acquired dormant brands and successfully relaunched them into the market. Their comments suggest that, with proper planning, an entrepreneur may be able to substantially increase his or her chances of success by reviving brands, rather than spending the enormous amount of capital required to build new brand image. Conclusions suggest that nostalgia targeting is not enough; the revived brand must be repositioned to satisfy today's customer values. Evidence also suggests licensing a revived brand name to unrelated industries may prove very profitable for the entrepreneur.
