Consumer Motivation for Reward Pursuit: A Culture-Based and Progress-Based Model of Loyalty Program Effectiveness

Aided by the exponential rate of globalization and digitalization, reward or loyalty programs (LPs) have attained global reach. Paradoxically, however, dropout rates of LPs have averaged over 75%. This disconcerting statistic, coupled with the lack of culture-specific insights in the literature, points to a research area of great theoretical and practical importance. To address the aforementioned issues, we develop a culture-based and progress-based model of consumer motivation that is especially applicable to LP members. Drawing on cross-cultural literature and goal pursuit theory, our research enriches a field that is inherently global in nature. Through a series of research propositions that elucidate how Western individualist (vs. Eastern collectivist) consumers are differentially motivated to pursue LP rewards, we advance theoretical understanding of reward-induced behavior across cultures and offer useful insights for global managers of LPs.     

Shares of the Rich and the Rest in the World Economy: Income Divergence Between Nations, 1820–2030

This paper analyses the forces determining per capita income levels of nations over the past millennium and the prospects to 2030. In the year 1000, Asian countries were in the lead. By 1820, per capita gross domestic product in Western Europe and the USA was twice the Asian average. The divergence had grown much bigger by 1950, but by the 1970s, several Asian countries – Japan, South Korea, Taiwan, Hong Kong, and Singapore – had achieved considerable catch-up. Since then, there has been a major surge in China and the beginning of a similar phenomenon in India. As a result, the Asian share of world income has risen steadily and, by 2030, will be fairly close to what it was in 1820. I conclude by comparing my projections for 2030 with those of Goldman Sachs, Perkins and Rawski, and Fogel.     

浅谈网上追逃的法律困惑及前瞻

网上追逃措施在打击刑事犯罪、抓获犯罪嫌疑人、保证犯罪嫌疑人迅速及时到案发挥了越来越重要的作用,但是由于法律对"网上追逃"缺乏具体明确的规范,实践中犯罪嫌疑人的羁押、移交程序随意、混乱,容易侵害犯罪嫌疑人的合法权益。本人认为应当尽快将其纳入刑事诉讼法进行规范,细化网上追逃程序,保护犯罪嫌疑人的合法权益。     

企业持续创新实现效能评价模型研究

基于企业持续创新实现机制,构建了企业持续创新实现模型,基于主成分投影法构建企业持续创新实现效能评价模型,并对云南省19家创新型企业的持续创新实现效能进行评价.在对评价结果进行深入分析后,发现制度结构要素是影响企业持续创新实现的最关键因素,完善的制度结构能改进和增强持续创新能力以及提高机遇捕捉能力.因而,企业要推动持续创新实现,必然要完善和改进产权制度、企业家管理制度、非正式制度等内部制度安排,同时,当地政府也要积极推进政策支持、营造公平竞争的市场环境.     

Examining the Draw of Diversity: How Diversity Climate Perceptions Affect Job‐Pursuit Intentions

Organizations must target talented applicants, who will often be demographically diverse, to attract the most competent and competitive workforce possible. Despite the bottom‐line implications of attracting the best and brightest, surprisingly little is known about how and why diversity recruitment strategies affect recruitment outcomes (e.g., job‐pursuit intentions). To gain insight into this question, we conducted an initial experimental study (N = 194) to test the premise that other‐group orientation moderates the relationship between perceived organizational value of diversity and job‐pursuit intentions. In a follow‐up experiment (N = 255), identity affirmation was examined as the mediating mechanism for the interaction observed in the first study. Mediated moderation analyses supported the proposed model. Collectively, the studies indicate that job seekers high in other‐group orientation are more intent on pursuing employment with organizations deemed to value diversity because they feel that their salient identities are likely to be affirmed. No such indirect effect is present for those lower in other‐group orientation.

江苏省城市洪涝韧性评价及影响因素研究

基于压力-状态-响应(PSR)框架,构建城市洪涝韧性评价指标体系,并运用基于实数编码加速遗传算法的投影寻踪模型(RAGA-PP)和灰色关联度分析法对江苏省各市洪涝韧性进行总体评价及影响因素分析。结果表明:13个地级市城市洪涝韧性指数由大到小排序依次为南京、苏州、无锡、常州、南通、镇江、徐州、泰州、扬州、连云港、淮安、盐城、宿迁;江苏省城市洪涝韧性呈现明显的两极分化趋势,苏南优于苏北;防汛物资储备调拨能力、公众灾害应急意识、居民人均可支配收入、第三产业占比、人均地区生产总值、排水管网长度和高等院校毕业生数等指标对城市洪涝韧性影响较大。     

两种基于投影数据恢复的低剂量CT重建方法比较

目的:低剂量CT重建已成为CT成像的研究热点,针对低剂量CT成像,文章对两种基于投影数据恢复的低剂量CT重建方法进行了讨论比较。材料与方法:这两种方法分别为基于投影数据非单调性全变分最小恢复的低剂量CT重建方法和基于投影数据惩罚加权最小二乘恢复的低剂量CT重建方法。我们通过数字体模仿真实验对两种方法分别进行了定性和定量比较分析。结果:实验结果表明,两种方法均能有效去除噪声、抑制伪影、提高低剂量CT重建图像质量。结论:重建时间方面,基于投影数据非单调性全变分最小恢复的低剂量CT重建方法更有优势。     

Opportunity Identification and Pursuit: Does an Entrepreneur’s Human Capital Matter?

Extending human capital approaches to entrepreneurship, an entrepreneur’s “inputs” relating to their general (i.e. education and work experience) and entrepreneurship-specific human capital profile (i.e. business ownership experience, managerial capabilities, entrepreneurial capabilities and technical capabilities) are presumed to be related to entrepreneurial “outputs” in the form of business opportunity identification and pursuit. Valid and reliable independent variables were gathered from a stratified random sample of 588 owners of private firms. Ordered logit analysis was used to test several theoretically derived hypotheses. With regard to the number of business opportunities identified and pursued, entrepreneurship-specific rather than general human capital variables “explained” more of the variance. Entrepreneurs reporting higher information search intensity identified significantly more business opportunities, but they did not pursue markedly more or less opportunities. The use of publications as a source of information was positively associated with the probability of identifying more opportunities, while information emanating from personal, professional and business networks was not. Implications for practitioners and researchers are discussed.      

快速校正天波雷达电离层相位污染的改进方法

时变的电离层会对天波超视距雷达(OTHR)回波信号相位进行调制,产生相位污染,导致回波谱展宽。最大似然估计(MLE)法具有比相位梯度法更佳的污染校正效果,但计算量非常大。通过引入投影近似子空间跟踪法,提出了一种改进的MLE方法。改进方法采用递归手段估计最大特征值对应的特征向量,避免了特征值分解过程,能够显著降低计算量,污染校正效果与MLE法相当。理论分析与仿真对比表明改进方法普适性强,计算量只有MLE法的万分之一,更适合工程实现。
