Involvement theory in constructing bloggers' intention to purchase travel products

Blogs recently have demonstrated their enormous marketing potential, and more and more travel advertisements are being posted in blogs. In light of this observation, this study aims to provide insights into the structural relationship among travel bloggers' involvement level, the advertising effect from blog messages, and travel bloggers' intention to purchase travel products. A travel blogger's purchase intention model was constructed and empirically tested. A total of 900 questionnaires were distributed to identified travel bloggers; 398 valid responses were returned. The data were examined with Structural Equation Modelling (SEM). The results demonstrated the positive impact resulting from the ad effect as well as the ad effect on purchase intention, which could be verified in travel blog environments. It also indicated that high-involvement travel bloggers are more likely to form favourable impressions with regard to ads in travel blogs. Travel blogs play a positive role in the processing of ad messages; brand management is essential to business marketers since brand attitude is the most influential factor related to the ad effect on purchase intention. Meanwhile, while ad attitude is not significantly effective concerning purchase intention, it remains essential in forming brand attitudes. Several implications for posting advertisements in travel blogs will be discussed and suggested in this paper.     

“边缘地带”解决“三农”问题成败规律探析

研究“三农”问题成败的角度有很多,但从地缘政治视野中去探究“边缘地带”这一特定空间区域的成败经验,目前尚属空白。二战后的“四小龙”、日本和以色列都是成功的案例,而印度、伊拉克、伊朗则是失败的案例。总结其中成功的经验和失败的教训后可得出这样一个结论,即“边缘地带”的国家和地区,必须采取符合当时形势要求的外交战略和自身定位,通过至少与一个全球强权国家结盟,争取机遇和资源,实现“三农”问题的解决。     

企业为何要即兴运作:对中国企业战略决策风格的一个检验

文章以中国企业为研究对象,全面探究了其战略决策中的即兴运作行为,认为即兴运作作为一种可供选择的战略行动模式而值得关注.文章的研究结论表明:即兴运作在中国企业是一个较为普遍的现象.企业对战略行动的选择是由多种因素综合驱动的,当企业的组织记忆水平越高、企业家导向越明显以及所面对的竞争环境不确定性程度越高时,企业就越可能采取即兴运作的战略行动方式;即兴运作虽然会对战略行动绩效产生负面影响,但组织柔性会显著降低其负面作用.     

地震灾害、创伤记忆与媒体的“心理危机干预”

地震不仅造成生命与财产损失。还有生理与心理的创伤。大众传媒不仅要沟通危机信息、承载创伤记忆,还要对记者的职业创伤、受众“不在场的悲伤”与幸存者的创伤体验担当心理援助的功能。传媒参与心理危机干预的传播效果如何,与传者的心理学专业素养、媒介内容生产的心理诉求以及媒介组织行为息息相关。     

Another look at long memory in common stock returns

We apply the modified rescaled range test to the return series of 1,952 common stocks. The results indicate that long memory is not a widespread characteristic of these stocks. But logit models of the event of a test rejection reveal that rejections are linked to firms with large risk-adjusted average returns. The maximal moment of a return distribution is also found to influence the event of a rejection, but not in a way suggestive of moment-condition failure. Evidence suggestive of survivorship bias is also uncovered. We conclude that there is some evidence consistent with persistent long memory in the returns of a small proportion of stocks.     

Value at risk and return in Chinese and the US stock markets: Double long memory and fractional cointegration

Given that the United States is an engine of global stock market while China is the largest emerging market with a cornucopia of anomalies in particular, it is vital to investigate the risk-return relationship in the two markets. This paper brings new insights not only into risk-return tradeoff, but also to the leverage effect, with the application of the fractionally co-integrated vector auto-regression (FCVAR) model capturing the fractional cointegrated relationship and long memory property. Results show that China stock markets own the property of double long memory but the US markets don’t. Most of all, in the US market, a positive risk-return tradeoff exists for the whole sample while after the crisis, even we find the negative relation, it’s not a volatility feedback effect but low risk and high returns. However, there is only a volatility feedback effect in China stock markets. Besides, there is a leverage effect in the US market, while Chinese market exhibits a reverse one, another anomaly, indicating significant difference in the two markets again.     

Antecedents and consequences of hotel customers’ psychological ownership

This study aims to broaden the current knowledge on the antecedents and consequences of customers’ psychological ownership (CPO) from new perspectives in the hotel context. Specifically, this study investigates how self-image congruity and functional congruity affect CPO through impression in memory based on self-congruity theory and also examines two types of customer engagement—customers’ social influence engagement and knowledge-sharing engagement—as new CPO outcomes. Using survey data collected from 433 Chinese hotel customers, this study finds that self-image congruity positively predicts CPO partially through impression in memory, whereas functional congruity positively influences CPO fully through impression in memory. Moreover, the findings indicate that CPO significantly drives customers’ social influence engagement and knowledge-sharing engagement. This study contributes theoretically to the CPO literature by further developing its linkages with congruity perceptions and customer engagement. Practical implications of the findings can help hotel managers effectively promote CPO and customer engagement.     

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。     

自适应约束下的双边全变差正则化超分辨率重建

在经典的双边全变差(BTV)超分辨率重建中,加权系数和正则化参数的恒定性导致重建结果边缘保持能力受限。为此,提出了一种自适应约束的BTV正则化先验模型。算法首先定义了图像的局部邻域残差均值以区分当前像素属于平坦区域还是边缘区域;然后针对加权系数的不变性导致边缘削弱的问题,利用边缘方向和垂直边缘方向扩散性的不同,设计自适应权重矩阵;最后根据代价函数的极值问题推导出迭代公式,从而进行图像的超分辨率重建,重建过程中采用自适应的方法确定正则化参数,以便求得代价函数的全局最优解,提高了算法的鲁棒性。实验结果表明：与双三次线性插值法和经典BTV算法相比,该算法取得了更好的视觉效果和更高的峰值信噪比,更多地保留了图像的边缘细节信息。
