Conditional Effects of Touch on Purchase Behavior

Interpersonal touch has been shown to affect consumer behaviors such as compliance with a request, impulse buying, and tipping behavior. In this study, we examine if the impact of touch on purchase behavior is gender specific, and if it depends on how much the individual likes the product. Findings indicate male consumers are more likely to purchase a product at low to moderate levels of perceived tastiness when they are touched by a female server, whereas females are less likely to purchase. However, the touch encounter doesn’t matter for either gender when a consumer really likes the product.

The challenge of Chinese state‐affiliated multinationals in benefiting from foreign subsidiary knowledge transfer: A criticism of light‐touch integration

Acknowledging the sharp growth of Chinese state‐affiliated multinationals and their strategic asset‐seeking investments abroad, this study investigates the effects of headquarters' home‐country political ties on the multinational‐wide benefits gained from subsidiary knowledge transfer in Chinese multinationals. It also looks at how these effects are mediated by organizational distance and social integration between headquarters and subsidiary. Based on a survey of 177 subsidiaries of 99 Chinese multinationals, we find that headquarters' political ties trigger organizational distance and hinder social integration between headquarters and foreign subsidiaries and these, in turn, hamper the potential benefits that Chinese multinationals derive from subsidiary knowledge transfer. This study identifies new challenges related to political ties and light‐touch integration in gaining benefits from subsidiary knowledge transfer.     

基于显著区域提取的红外图像舰船目标检测

针对复杂海面背景下红外图像舰船目标由于灰度不均匀、海杂波干扰大等因素造成的自动检测虚警率高、准确率低的问题，提出了一种显著区域提取和目标精确分割相结合的红外舰船目标检测方法。首先，利用基于图论的视觉显著性(Graph-based Visual Saliency ,GBVS)模型计算待检测图像的显著图，使得目标区域信息增强；其次，结合舰船目标先验信息（长短轴、面积等），利用多级阈值划分算法提取关注的显著区域，并确定原图中候选目标区域；最后，利用空间约束模糊C均值(Fuzzy C-Means,FCM)算法对候选区域进行分割，结合目标先验知识对分割区域筛选并输出目标位置。所提方法在公开数据集IRShips上与相关方法进行比较，结果表明，相比直接进行全图目标搜索的方法，所提方法不仅准确率高、执行速度快，且检测目标的位置更加精确。

变电设备红外线热成像诊断技术的准确性分析

红外诊断技术是一种新型诊断技术,为变电设备的热诊断提供了很好的诊断方式,该种诊断方式有着不解体、直观性、快速性、准确性的特征,也适宜用在大面积检测中,同时,该种诊断技术也能够与其他检测方式联合使用,定位故障的具体位置,这就可以有效提升检修的便利性。但是,影响红外线热成像诊断技术准确率的因素是多种多样的,在进行诊断时,必须要合理地控制其测量环境与测量方式。本文主要分析影响红外线热成像诊断技术准确性的因素,并提出相关的解决措施。     

Product Touch and Consumers’ Online and Offline Buying: The Role of Mental Representation

As offline retailers struggle to compete with online ones, the importance of a consumer’s ability to touch a product prior to purchase becomes important to study. Prior research has found inconsistent results on whether product touch facilitates consumers’ product-related decision making. Some studies report a positive effect, whereas others do not. The current research reconciles this inconsistency and draws retailing implications. Across three experiments, we show that the effect of product touch on consumers’ purchase intentions and willingness to pay for a product being evaluated is evident when consumers’ mental representation of the product is concrete, but not when abstract. We further show that perceived risk and perceived ownership simultaneously mediate this moderating effect of mental representation. Implications are drawn for both offline and online retailers.     

Do time constraint and emergency purchase situation exert same influence on shopping? A study under haptic touch influence

Marketing literature has identified emergency purchase situation and time constraint as important situational influences. However, both of them are often equated with each other as both require shopping to be done in a short time. This study makes an attempt to eliminate the confusion by studying the impact of two situation variables on product evaluation and purchase intention under the influence of haptic touch. Two studies conducted to test the hypotheses show that while emergency purchase situation has a significant impact under no-touch influence, the same can not be said for time constraint situation.     

基于红外图像的林火识别方法及实现

森林火灾是一种突发性强、破坏性大且处置救助较为困难的自然灾害,会对森林、森林生态系统和人类带来一定危害和损失。早期的林火判别多基于温度、烟雾以及24小时图像监测实现,主观性强,标准单一,且误报率高。如何快速发现林火目标并及时报警扑灭,已经成为国内外学者研究的热点之一。文章基于红外热像仪,对大量森林背景及模拟林火状态进行了图像和温度数据的采集,首次提出了基于温度标准差方法进行热源识别的概念,得出了不同地点、不同时间段森林背景的温度标准差分布,以及明火温度在各阶段的波动范围,为林火的预防和监测提供了重要依据。同时,通过对干扰源进入前后的红外图像进行预处理和分析,对比目标热源的像素面积变化率及其圆形度,即可准确实现部分干扰热源的排除。实验结果证明,将此基于红外图像的热源初判原则与干扰源排除的规律应用于林火监测,方法简单有效,准确率高,对降低森林火灾的发生率,提高社会经济效益有着重要的作用。
