Image transfer from malls to stores and its influence on shopping values and mall patronage: The role of self-congruity

Little research attention has been paid to the image transference from a shopping mall to its stores. The study reported in this article proposes an integrative model dealing with the image transference phenomenon from malls to stores and its implications in terms of creating value for shoppers and enticing mall patronage. Structural equation modeling is applied to data collected from shoppers in two urban North-Amercian shopping malls. The findings are broadly supportive of the proposed model. Mall image spills over the image of the stores located in the mall, and this occurs through a shopper's self-congruity mechanism. Furthermore, the mall's image dimensions influence hedonic shopping value through self-congruity. The stores’ image dimensions differentially influence utilitarian and hedonic shopping values assessments. Both types of shopping values are strong drivers of mall patronage. The study also discusses the implications of the findings as well as its limitations and directions for future research.

Characterizing land disturbance in Atewa Range Forest Reserve and Buffer Zone

Changes in land cover of protected areas and their buffers have serious implications on the conservation of biodiversity within such biomes because land use has been recognized as one of the major drivers of biodiversity change. Atewa Range Forest Reserve is one of Ghana's Upper Guinea Forests declared as a Globally Significant Biodiversity Area (GSBA). But the reserve is under threat from several human disturbances which could impact on the land cover of the reserve.This study examined the spatial and temporal changes in land cover of Atewa Range Forest Reserve and it's buffer between 1986 and 2013 using remote sensing. Land use and land cover (LULC) classification and change detections were undertaken using one Landsat Multispectral Scanner (MSS) image of 1986 and Landsat ETM+ images of 2003 and 2013.The study also investigated the driving forces of LULC and the effectiveness of the Forest and Wildlife Policy of 1994 in the management of the reserve.Results of image classification showed that much of the peripheral closed and open vegetative covers have been converted to farms and bushes with little disturbance within the interior of the reserve. The study revealed that, the conservation management policies were yielding very little results due to a number of policy deficiencies including low staff strength, lack of logistics and low remuneration. Enforcement of legal instruments against illegal logging, small scale mining and farming activities within the reserve, improvement in the staff strength and their condition of service, intensification of public education on the value of forest and the need to protect it are some of the major recommendations that could curb encroachment on the reserve.     

一种计算图象速度的新方法

本文描述的是一种计算图象速度的新奇技术,用一个交又时延线对图象速度的两个相互垂直的分量分别进行计算。如果图象面积是已知的,计算图象速度时就不需要图象面积的其它知识,两个交叉时延线是需要的。该方法作为模拟超大规模集成电路的一种工具是非常适合的。

图像浮雕算法及其在防伪印刷中的应用

图像浮雕技术是指通过一种特殊处理,改变二维平面图像中的有效内容、图像边缘或者特定区域的颜色值,增强图像立体显示效果的技术。基于孔斯曲面理论,本研究提出了一种新的矢量图像浮雕算法,即通过矢量线条的局部变形来再现图像雕刻般凹凸效果。实验表明,通过上述方法得到的图像浮雕图案克服了现有算法中固定浮雕角度偏移的缺陷,所表现的浮雕凹凸效果更加细腻,既能达到美观的艺术效果,同时作为一种非常重要的版纹防伪元素在防伪印刷中有着广泛的应用价值。     

不同USM锐化参数下图像频谱变化研究

为了研究图像的锐化机理和作用,探讨图像锐化处理对图像频谱成分的影响,通过编程生成12种不同空间频率的正弦波图像,用Photoshop软件将这12种图像组合成一幅完整的灰度图像,作为进行锐化处理的原稿。将原稿图像进行不同参数（数值及半径）的虚光蒙版锐化处理,使用Matlab软件对原稿及经锐化的图像进行二维傅立叶变换（FFT）,随后提取上述12种频率对应的傅立叶谱值,将锐化后的值与原稿对应值相减,对其进行分析和研究。通过对频谱曲线进行比较分析,结果表明：USM锐化对图像的频谱增强作用随USM半径、数值的增大而增大;USM锐化对图像频率成分的增强作用并不均衡;USM半径设置较小而USM数值设置较大时,对图像中高频成分的增强效果较明显;USM半径设置较大而USM数值设置较大时,对图像中低频成分的增强效果较明显;当USM锐化参数（数值、半径）设置都较小时,对图像中高频的部分频谱有减小作用。     

An Analysis of Regional Positioning and Its Associated Food Images in French Tourism Regional Brochures

Summary

The image of France has often been associated with that of food and wines and images of food products, vineyards and restaurants have traditionally dominated national and regional promotional strategies and tour operators' brochures alike. Indeed, food represents a powerful eye-catcher and a strong symbol of quality of life and authenticity, as a result it has represented an important theme used in advertisements. However, the food theme is in fact multiple and can also be used to portray symbols of cultural identify, communication and status. Therefore, the present study first aims at identifying the different food images that can be used by tourism advertisers in their promotional material. Secondly the study aims at investigating how different food images can be used for specific destinations' positioning strategies. The research uses a content analysis to identify the types of food images used in 19 French regional tourism brochures. Results show that country products/dishes and raw/natural products dominate food images followed by wine and vineyards images. Images of food producers, chefs, restaurants and the presence of people in the pictures on the other side are underrepresented. Parallels between the categories of food images used in brochures and the corresponding positioning strategies chosen by the regions are not very strong. Nevertheless, the study indicates that regions that position themselves on the traditional/rural/authentic theme use mostly images of raw products, country products and market scenes while only a few regions position themselves on the gastronomy dimension. In other terms, the cultural dimension of food as an identity marker for the regions is its principal use, and images of food associated to communicating/sharing or to status/lifestyle statements are rarely used in French regional brochures.     

Antecedents and consequences of destination image gap

The purpose of this study is to examine the antecedents that explain changes to the image that first-time tourists have (pre- and post-visit image gap) of a destination and its impact on satisfaction and loyalty through the design and validation of a model. The research has been carried out using a sample of 411 tourists in Tenerife (Spain). The involvement with the trip, the time dedicated to the search for information, and the number of attractions visited influence the change in cognitive image. The factors that explain the time spent searching for information are uncertainty, involvement, and duration and intensity of the visit. The positive gap in the image generates greater satisfaction, which has a positive impact in the loyalty.
