Consequences of a green image of drone food delivery services: The moderating role of gender and age

Drone food delivery services play a significant role in protecting the environment, because the services are operated by batteries that can be charged with electricity. Therefore, this study tried to examine a green image in the context of drone food delivery services. More specifically, this study proposed that a green image of drone food delivery services plays an important role in the formation of attitude toward using the services. In addition, it was hypothesized that the attitude has a positive influence on behavioral intentions including intentions to use, word‐of‐mouth intentions, and willingness to pay more. Lastly, the moderating role of gender and age was proposed during the theory‐building process. A theoretical model, which included 12 hypotheses, was developed and tested using a total of 427 samples collected in Korea. The data analysis results showed that a green image of drone food delivery services has a positive influence on attitude toward using the services, which in turn positively affects three subdimensions of behavioral intentions. Furthermore, gender and age played partly as a moderator. The current paper was the first to study the green image of drone food delivery services, so the findings of this study mean a lot to the theoretical aspect.     

A destination imagery processing model: Structural differences between dream and favourite destinations

The present paper aims at understanding how destination imagery is processed in tourists’ working memory. The research focuses on two highly desirable, but contrasting, destination brand categories: Favourite Destination, which involves retrospective memory of positive experiences in situ; and Dream Destination, based on tourists’ prospective memory. Through an online multilingual survey, 23,446 responses consisting of perceptions, evoked by way of free-recall, associated to Dream and Favourite Destinations, were collected. Findings point to clear structural differences between the imagery of Dream and Favourite Destinations. Additionally, a theoretical destination imagery model that offers a basis for future studies is proposed, and some managerial implications of significant relevance to destination marketing are discussed.     

河流工程中的图形绘制与处理

在河流工程领域,不管是实体模型还是数学模型,对多样化的数据和丰富多彩的图形的需要越来越强烈,旧的表现形式已经被层出不穷的新的、信息量大而且地位高的2D、3D图形所取代,因此在工程中合理地选择绘图方式和开发软件就变得十分重要。以实际操作经验为基础,从基本操作类到二次开发类再到高端图形图像开发类,详细地讨论了在河流工程中各种图形的绘制和处理方法选择,具有一定参照价值。     

稀疏气泡流动的粒子跟踪测速技术研究

采用动态阈值技术实现了对气泡图像的正确分割，利用灰度加权方法提高了气泡颗粒的定位精度。根据稀疏气泡流动图像的特点，提出了一种新的基于相关的粒子跟踪测速算法（2-HPTV）。通过进行两时刻中围绕待研究气泡所取的两个小的诊断窗口的相关运算，成功实现了气泡颗粒的轨迹追踪。实验表明本文算法较传统的PIV技术在测速精度上有很大程度的提高，与4帧粒子跟踪测速算法相比，降低了对摄像机帧频的要求，具有较强的实用性。     

From rationality to hyperreality: paradigm poker

This paper, following McGoun's (1997) seminal article comparing the economy of financial securities to a hyperreal poker game, argues that finance and accounting researchers should take the “linguistic turn” that has rejuvenated theory and research in many, if not most, of the social science and humanities in recent decades. In general terms, this means following Ludwig Wittgenstein's language game paradigm rather than Karl Popper's scientific deductive hypothesis testing methodology. The paper illustrates this by drawing on some of Jean Baudrillard's' ideas, particularly his concept of hyperreality and his phases of the image theoretic.The paper presents a poststructuralist genealogical analysis of the radical ruptures and reformulation of the meaning attributed to the accounting sign of earnings over the feudal, counterfeit, production, and simulation eras. It concludes that, as with many other signs in contemporary society, the earnings sign no longer has any relationship with, nor does it any longer refer to, any real or intrinsic profit but instead floats ungrounded in today's financial economy.The paper recommends that researchers in finance and accounting adopt paradigms from literary theory, semiotics, linguistics, and semiology rather than continue to rely on economics-based theory, which has lost its power for explaining and predicting happenings in today's financial economy of self-referencing models and images.

户籍歧视对劳动报酬差异的影响

在我国，户籍歧视是形成劳动力市场分割的重要原因，它不但通过阻碍劳动力流动造成城乡收入差异，也会促成农民工和城镇工人之间劳动报酬的差异。本文利用中国健康与营养调查（CHNS）多年的数据，对我国户籍歧视影响劳动报酬差异的程度进行计算和分析。结论表明，近几年户籍歧视现象并没有明显改观，政府在制定相应政策时，仍需关注这方面的问题。     

Building strong brands in Asia: selecting the visual components of image to maximize brand strength

Asian brands have often struggled to develop quality images. The visual aspects of branding have received little attention on how they might be used to strengthen brand perceptions in Asia. Guidelines for designing visual brand stimuli are developed using evaluations of logos in China and Singapore. There is a significant relationship between design and the responses companies seek, including positive affect, perceptions of quality, recognition, consensus in meaning, and feng shui. How designs are perceived, and their effect on consumer responses, were similar between China and Singapore. Companies are encouraged to leverage design to strengthen their brands. In particular, they should select logo designs that are elaborate, natural, and harmonious as these created positive affect and quality perceptions, clear meaning, true recognition, and feng shui. Many of these relationships hold in the United Sates as well, implying that the visual aspects of brand strategies may accomplish companies' goals across international borders.

含三维内裂纹透明类岩石材料破坏红外热像试验研究

由于目前针对含三维内裂纹的岩石破坏红外热像特征的研究较少,本文基于预埋浇注法制作含内裂纹类岩石试件,开展了单轴压缩块体试验和巴西圆盘劈拉试验,得到含内裂纹的岩石破坏过程,监测内裂纹扩展及试件破坏过程中的红外热像特征,得到以下结论:(1)含三维内裂纹的块体试件在单轴压缩下,在预制内裂纹面上发生剪切破坏;(2)块体试件在单轴压缩作用下红外热像特征明显,在破坏时,在预制内裂纹面处急剧升温;(3)含三维内裂纹巴西圆盘试件在预制内裂纹尖端发生翼型裂纹扩展,边缘带有针刺状Ⅲ型裂纹参与特征,最终翼型裂纹与上下表面贯穿;(4)巴西圆盘试验的红外热像特征与块体单轴压缩不同,在断裂面处未发生明显变化。研究结果为研究三维内裂纹的扩展规律及内裂纹扩展破裂的红外热像规律可提供一定的试验参考。
