Effects of augmented reality technology characteristics on customer citizenship behavior

In recent years, augmented reality (AR) technology has received considerable attention from academics and practitioners. Although AR technology has a bright side, its dark side has been relatively overlooked. Therefore, this study aimed to investigate the effects of AR technology characteristics on customer citizenship behavior via two conflicting mechanisms: customer immersion and customer fatigue. The study also explored the boundary conditions of customer experience. A total of 247 questionnaires were collected from customers who had prior experience of using IKEA's AR mobile shopping application. A structured model was analyzed using SmartPLS 3 and PROCESS Macro for mediation and moderated mediation effects. The study enriches the current knowledge on AR technology by demonstrating that AR technology can lead to customer citizenship behavior in relation to a brand's AR technology. Interestingly, customer immersion was found to positively mediate the relationship, but customer fatigue was found to negatively mediate it. Furthermore, customer experience was found to strengthen the positive mediation effect of customer immersion and weaken the negative mediation effect of customer fatigue.     

Are social media bad for your employees? Effects of at-work break activities on recovery experiences

Since social media has become a fundamental part of the daily activities of people, the purpose of this study was to explore social media use by focusing on job demands that may explain why employees perceive social media are vital for them at work. Further, this study seeks to understand how employees use social media at work to experience recovery. Questionnaires were collected from current frontline hospitality non-managerial and managerial employees in the United States. Structural equation modeling was employed to analyze data. Results of the study confirm that at-work break activities including social and non-media break activities can be a channel for employees to experience recovery and deal with job demands. Moreover, the results suggest that at-work break activities are an important mediator between job demands and recovery experiences. Social media break activities also moderated the mediation effect of non-social media break activities between job demands and recovery experiences.     

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。     

Does local government competition aggravate haze pollution? A new perspective of factor market distortion

Haze pollution has become a new threat to China's sustainable development, but it may be that local government behaviour can play an important role in the prevention and control of pollutants. A dynamic spatial autoregressive (SAR) model is used to study the relationship between local government competition and haze pollution. To further explore the indirect impact of factor market distortion on haze pollution and control potential endogeneity problems, a newly developed intermediary effect model that incorporates the characteristics of the generalized method of moments (GMM) is utilized to explore how factor market distortion indirectly affects haze pollution. The research results show that regional haze pollution in China is characterized by significant spatial correlation, and local government competition has a positive impact on haze pollution; that is, local government competition exacerbates haze pollution. In general, local government competition not only directly leads to an increase in haze pollution but also further intensifies it by distorting the local factor market, and the intermediary role of factor market distortion is approximately 7.04%. The results of the regional inspection found that competition among local governments in the eastern region did not lead to haze pollution, and distortion of the factor market did not exist as an intermediary effect. However, both direct and intermediary effects are significant in the central and western regions. Therefore, an official performance appraisal system that includes ecological constraints should be established to guide the benign transformation of local government competition, and an environmental management mechanism must be developed for joint prevention and control to reduce haze pollution. In addition, the free flow of factors and marketization are equally important.

我国省域农业隐含碳排放及其驱动因素时空动态分析

[目的]我国区域农业发展模式由于气候、环境的不同存在较大的差异,而目前针对农业隐含碳的时空动态研究较为缺乏,导致对于区域减排目标的设定缺乏全面的考虑,无法实现农业碳减排的效率性和公平性。因此,有必要分析农业隐含碳排放在不同省域的特征并分析其驱动因素,为制定体现地区间公平性且有效率的碳减排政策提供依据。[方法]文章利用2002年、2007年和2012年3年的投入产出表估算我国各省(市、区)农业隐含碳排放量,根据Kaya恒等关系将其分解为经济规模、经济结构、一般农业技术进步和低碳农业技术进步4类影响因素,并利用LMDI分解分析法对这4类影响因素的驱动力进行了分析。[结果]2002—2012年我国大部分地区农业隐含碳排放量呈上升趋势,空间上呈现从西到东、从南到北逐渐增加的分布规律,经济规模效应在各省份均呈正向驱动,且在经济发展较为迅速、经济增长后劲较强的地区驱动效应逐渐增强;经济结构效应在大部分省份呈负向驱动,且在重型工业的聚集区域负向效应逐渐增强;一般农业技术因素正向驱动区域逐渐扩散,且在农业大省正向驱动效应逐渐增强;低碳农业技术进步因素在东部发达地区负向的驱动效应较强,在西部驱动效应较弱。[结论]在未来的农业减排政策制定过程中,需要充分考虑不同地区的经济发展、产业结构、农业生产等特点。     

基于主客视角的苏南传统村落旅游地乡愁的时间特征

“记得住乡愁”是乡村旅游和乡村振兴的重要内容。本文基于居民和游客视角,以苏南传统村落为案例地,探讨乡愁的时间特征。结果表明：（1）乡愁主体方面：相对暂居村落的外来人口,三代以上的世代居民对家乡乡愁情感更加强烈;出生在1950—1959和1960—1978年间的这两代游客较多成长在乡村,乡愁文化感知相对更高;离开家乡在外工作生活时间越长的游客在传统村落旅游时,其乡愁情感和乡愁记忆比起未离开家乡或离开家乡较短的人更加强烈。（2）乡愁触点方面：触发居民和游客乡愁的季节集中在秋天和冬天,天气集中在下雨和落雪时,时辰集中在深夜和傍晚时,节庆集中在春节、中秋节、清明节和家乡特有节日,假日主要集中在周末、寒假和“十一”国庆假期。（3）乡愁记忆方面：主客乡愁记忆都主要集中在童年,其次是青少年,最后是成年和老年;游客产生乡愁的频率比居民频率相对高。（4）乡愁载体回忆顺序：主客乡愁载体都会提到“家”和“乡”相关场所和空间,其回忆的顺序是家人、家、家乡和国家。文章最后总结了乡愁旅游开发的启示。     

后危机视野下福建省经济格局演变及其影响机制

［目的］后危机时代是目前我国各地区经济发展面对的一个巨大变量，也是近年来区域经济发展关注的焦点话题。［方法］选取福建省县域经济的5项指标作为解释变量，利用探索性空间分析方法和地理加权回归模型，对2010—2015年福建省县域经济格局及其驱动机制进行探讨。［结果］（1）总体上看，福建省经济空间格局变化较小，呈现东南高西北低的态势，重心向福州、莆田地区转移，省内发展均质化与极化现象并存；（2）产业结构调整与城镇化水平提升主导省内经济重心在东西方向上的移动，两者的空间格局具有相似性；（3）创新投入与金融零售业的变化主导了经济重心南北向的移动，其与各市县的经济基础和产业调整政策密切相关。［结论］在后危机时代福建省需根据市场特征推进区域协同发展、实现产业结构调整、促进区域共同富裕； 地方经济政策应与自身经济发展特征相适应，实现区域经济可持续发展。     

基于个性化的江西省乡村旅游空间分布及评价

［目的］通过对个性化的江西省乡村旅游区的空间分布进行研究，并对个性化的红色旅游资源进行评价，以期对乡村旅游的发展提供新的思考路径，建立具有个性化的乡村旅游体系。［方法］运用GIS102操作平台对江西省119个红色乡村旅游区的空间分布情况进行研究，通过计算最临近点指数、地理集中指数和核密度计算分析其空间分布特征。以资源要素价值、开发价值和社会效益组成评价层，下分14个指标，对江西省红色旅游资源进行评价研究。［结果］(1)江西省红色旅游区分布类型为集聚型，分布不均衡； (2)在评价准则层中，旅游资源要素价值权重最大，为0647 9，其次为社会效应，权重为0229 9，开发条件权重最低，为0122 2； (3)指标层权重排名前三位的依次为资源完整性、教育性和组织管理，权重值分别为0162 0,0116 5和0111 7。［结论］江西省乡村红色旅游区数量较多，但整体呈集聚型分布特点； 旅游资源要素价值权重最高，且整体资源禀赋较强，社会带动效应明显，具有极强的开发价值。     

COVID-19: The effects of job insecurity on the job engagement and turnover intent of deluxe hotel employees and the moderating role of generational characteristics

COVID-19 has caused an unprecedented crisis in all industries around the world. This study sought to verify that job insecurity, as perceived by deluxe hotel employees, significantly affects their job engagement and turnover intent and to determine the moderating effect of generational characteristics. The finding showed that perceptions of job insecurity had negative effects on the engagement of deluxe hotel employees. Also, employees’ job engagement can decrease turnover intent. The engagement of employees fully mediated the relationship between perceptions of job insecurity and turnover intent, and job insecurity caused by COVID-19 had a greater influence on Generation Y than Generation X in reducing job engagement, indicating that the negative impact of job insecurity is higher in Generation Y.
