Personalisation–privacy paradox: The effects of personalisation and privacy assurance on customer responses to travel Web sites

Personalisation refers to individualizing products, services, and contents according to customer interests and preferences. In order to deliver appropriate personalised offerings, firms inevitably need to collect rich customer data profiles. Prior research suggests that personalised services lead to positive customer responses such as increased willingness to disclose personal information and make purchases. However, another stream of research emphasizes negative outcomes of personalisation – namely, privacy concerns surrounding the use of personal information and associated negative effects on behaviour. The objectives of this study are twofold: (1) to examine how privacy assurance affects proximal outcomes of personalisation, such as perceived usefulness and privacy concerns; and (2) to identify the role such outcomes play in predicting customer behavioural responses, such as willingness to disclose personal information and make purchases. Our findings show that enhancing privacy assurance increases the perceived usefulness of services and decreases customer privacy concerns. Moreover, customer behavioural responses are positively related to the perceived usefulness of services and negatively associated with privacy concerns. However, despite the positive effects on perceived usefulness and purchase intentions, personalisation has no effect on privacy concerns and intentions to disclose personal information.     

基于MBP算法和深度学习的人脸识别

为了解决在深度学习提取人脸图像特征时,易忽略其局部结构特征和缺乏对其旋转不变性学习的问题,提出了一种基于单演局部二值模式(MBP)与深度学习相结合的高效率人脸识别方法。首先,用多尺度单演滤波器对图像进行滤波,得到幅值和方向信息;其次,用LBP算法和象限比特的方法进行编码,分块计算组合其直方图特征;然后,将提取的单演特征作为深度信念网络(DBN)的输入,逐层训练优化网络参数,得到优异的网络模型;最后,将训练好的DBN网络在ORL人脸数据库上进行人脸识别实验,进行识别率计算,其识别率为98.75%。所提出的方法使用无监督的贪婪算法,隐藏层设定为2层,使用反向传播算法优化网络。相较于已知的人脸识别方法,MBP+DBN算法对光照、表情和部分遮挡变化具有较好的鲁棒性,在人脸识别中识别率较高,具有一定的优势,为图像特征提供了一种新的识别方法。     

The role of perceived behavioural control in the constraint-negotiation process: the case of solo travel

This study extends the leisure constraint-effects-mitigation model to the perceived behavioural control (PBC)- constraint-negotiation model by adding PBC. Three competing models were tested to determine which model best fits the data. Results suggested that PBC mediates the relationship between motivation and negotiation, and there is a direct path from motivation to participation. Findings contribute to deepening and broadening the theory of leisure constraint negotiation because the new variable was successfully added to the original model and the model was extended to new settings (i.e. solo travel and non-Western).     

Nonparametric Estimation of Oligopsony Power in First‐Price Auction

This paper proposes a nonparametric procedure to estimate market power for first‐price auction data and applies the procedure to cattle procurement markets. Most previous studies have used parametric methods, which require specific functional forms for retail demand, input supply and processors’ cost equations. However, researchers often find that market power estimates from parametric methods are sensitive to the choice of functional forms and specifications. An application to data from cattle procurement experiments shows that our nonparametric approach greatly outperforms commonly used parametric methods in estimating the degree of market power. While parametric estimates are sensitive to functional form specification and are at least 90% smaller than ‘true’ market power indices, estimates from our nonparametric procedure deviate from the actual value by no more than 25%.     

南方丘陵区新增耕地质量空间特征研究*——以江西省宜春市为例

［目的］粮食安全的根本是在耕地,关键在于耕地质量。目前新增耕地主要源于土地开发项目、城乡建设用地增减挂钩土地复垦项目等,这些新增耕地需要对其开展耕地质量等别评定工作,了解新增耕地的质量状况,分析其空间特征,这对落实国家耕地保护制度、开展农村土地整治工作等具有重要作用。［方法］文章以南方典型丘陵区域——江西省宜春市作为研究区域,在新增耕地质量评价的基础上,运用地统计学、景观生态学、Arcgis空间分析技术和典型相关分析方法,研究宜春市新增耕地质量的空间特征,掌握耕地质量等别的分布规律,了解耕地质量的影响因素,为制定合理的耕地资源利用与保护政策提供依据。［结果］（1）Moran′s I值结果表明宜春市2014年新增耕地利用质量在空间分布上的空间自相关性最强,而耕地自然质量空间自相关性最弱。（2）景观破碎度指数结果表明优、高等别的新增耕地质量破碎度大于中、低等别的; 多样性指数结果表明新增耕地质量多样性指数比较大; 优势度指数结果表明新增耕地质量等别优势度指数比较小,与多样性指数结果相呼应; 均匀度指数结果表明,新增耕地质量等别均匀度指数相差不大,新增耕地质量等别比较均匀。（3）质心结果表明2013—2014年间宜春市新增耕地质量的格局整体上是向西南方向变化。［结论］宜春市新增耕地质量不高; 新增耕地的利用水平差异性较小,自然本底状况差异较大; 新增耕地质量等别类型多,各质量等别类型耕地均有增加,耕地质量参差不齐,较高等地的新增耕地相对低等地而言更破碎化; 新增耕地的开发格局向着西南方向移动; 该研究为南方丘陵区的新增耕地保护提供了一定的参考依据。     

Impacts of Market Reform on Spatial Volatility of Maize Prices in Tanzania

Maize is one of the major staples and cash crops for many Tanzanians. Excessive volatility of maize prices destabilises farm income in maize‐growing regions and is likely to jeopardise nutrition and investment in many poor rural communities. This study investigates whether market reform policies in Tanzania have increased the volatility of maize prices, and identifies regional characteristics that can be attributed to the spatial price volatility. To achieve the objectives, an autoregressive conditional heteroskedasticity in mean (ARCH‐M) model is developed and estimated in this study. Results show that the reforms have increased farm‐gate prices and overall price volatility. Maize prices are lower in surplus and less developed regions than those in deficit and developed regions. Results also show that the developed and maize‐deficit regions, and regions bordering other countries have experienced less volatile prices than less developed, maize‐surplus and non‐bordering regions. Our findings indicate that investments in communication and transportation infrastructures from government and donor countries are likely to increase inter‐regional and international trade, thereby reducing the spatial price volatility in Tanzanian maize prices in the long run.

太行山区耕地整理适宜性评价及障碍因子诊断——以河北省涞源县为例

[目的]耕地整理适宜性评价是土地整治规划的基础,可以为划定耕地整理重点区域、确定耕地整理项目和整理时序提供依据。[方法]文章以位于太行山区的涞源县为研究区域,以现状耕地图斑为评价单元,经独立性分析后选取地形坡度、表层土壤质地、灌溉保证率、耕地系数、与道路距离、与城镇中心距离、地质灾害易发性7个评价指标,运用贝叶斯概率模型计算各指标权重及未整理耕地的整理后验概率,并得到研究区未整理耕地的适宜性空间分布。同时根据改进的障碍因子诊断模型,分析了各适宜整理区的障碍因子并提出相应的整理措施。[结果](1)在影响涞源县耕地整理的各因素中,影响程度从小到大依次是表层土壤质地、与城镇中心距离、耕地系数、地形坡度、与道路距离、地质灾害易发性和灌溉保证率;(2)在涞源县未整理耕地中,高适宜整理区与较适宜整理区占未整理耕地的20.79%,可作为涞源县下一步耕地整理的选择;(3)制约涞源县全域耕地质量的障碍因子是灌溉保证率,整理过程中应根据实际情况科学寻找灌溉水源、结合地形条件采用蓄、引、提相结合的方式合理布设农田水利设施,提高水资源利用率。[结论]该文可为太行山区更科学合理地开展耕地整理项目提供依据。     

吉林省农产品进出口对农业经济增长的效应———基于出口扩展型生产函数的实证研究

吉林省是一个农业大省,农产品进出口在整个对外贸易中占有举足轻重的地位,进出口贸易与经济增长之间的相互关系历来也是学术研究的重点。文章首先分析吉林省农产品贸易的发展状况与特点,研究了吉林省农产品贸易对农业经济的贡献率与拉动率;然后以柯布道格拉斯生产函数为基础,构建出口扩展型生产函数模型,对吉林省农产品进出口与农业经济增长,农业劳动投入、资本投入与农业经济增长的关系进行了实证分析,结果表明吉林省农产品进出口、农业固定资本投入对农业经济增长均具有正向的促进作用,农业就业人数的变化对农业经济增长的作用不显著。其中吉林省农产品出口额每增加1%,会促进农业地区生产总值增加0.198%,进口每增加1%,促进农业经济增长0.205%,农产品进出口总额每增加1%,农业地区生产总值增加0.227%。因此,吉林省要努力发展外向型农业,提高优势农产品在国际市场上的份额;同时增加农业资本投入,优化投资结构。     

Transformation and Rebirth of Chinese Brands: A Case From the Hotel Industry

ABSTRACT

Chinese domestic brands have developed rapidly in recent years, and yet few of them have entered global competition as product or service brands brands with exceptions such as Huawei. In addition, the evolution of Chinese brands has hardly been understood or introduced properly by international business educators. In this article, we identify the development patterns of Chinese domestic brands by using a local hotel brand as an example. Particularly, we examine and discuss how a Chinese brand can be established with specific positioning, brand image, and product offering, as well as how the brand can grow by vertical and horizontal extensions based on balancing market opportunities and the brand’s own capabilities. Moreover, we expect this research to facilitate the understanding of Chinese brands among international business education.
