ADC量化位数对阵列天线GNSS接收机的影响

在处理全球卫星导航系统（Global Navigation Satellite System,GNSS）卫星信号时,针对模数转换器（Analog-to-Digital Converter,ADC）量化位数不同导致输出的信号信噪比下降的问题,推导了阵列天线波束形成后输出信号的信噪比理论计算模型,分析了ADC量化位数对阵列天线抗干扰GNSS接收机的性能影响。在7阵元天线且ADC量化位数为10的条件下,理论模型分析和数据仿真结果表明最大抗干扰能力约为85 dB。通过确定ADC量化位数与抗干扰GNSS接收机抗干扰能力之间的关系,其结论为工程应用中抗干扰GNSS接收机的ADC选型和设计提供了理论依据。     

The role of cultural values in green purchasing intention: Empirical evidence from Chinese consumers

Environmental problems, especially in the case of water and air pollution, are the harmful result of the overconsumption of fossil fuels as well as various forms of industrial sewage water discharge. Recently, growing environmentally friendly purchasing behaviour of consumers has become regarded as an effective method for alleviating such environmental problems. Due to concerns regarding the natural environment, consumers have increasingly begun to exhibit favourable attitudes towards environmentally friendly products, and as a result, are more likely to purchase “green” products. However, green purchasing behaviour of consumers varies across different nations and cultures. This study aims to reveal how Chinese cultural values (specifically, the Doctrine of the Mean) influence green purchasing intention of Chinese consumers. As the lifestyles of consumers will be deeply affected by their cultural values, this study examines the mediating effects of the four dimensions of Chinese lifestyle have on consumers. At the same time, environmental knowledge is considered as a moderating variable in order to investigate the relationship between the Doctrine of the Mean and green purchasing intention. The study’s data were collected from Chinese consumers. Empirical results reveal that such Chinese cultural values are positively associated with green purchasing intention, and that three dimensions of consumer lifestyle (namely leadership, cost consciousness and development consciousness), are all found to play mediating roles in the relationship between the Doctrine of the Mean and green purchasing intention in Chinese consumers. The moderating effects of environmental knowledge are exhibited in the influence of leadership as well as development consciousness on green purchasing intention. The study’s findings have theoretical implications for understanding green purchasing intention as well as behaviour of Chinese consumers further. The study’s findings also present practical implications for how to promote green purchasing intention in Chinese consumers better.     

Impact of family income in early life on the financial independence of young adults: Evidence from a matched panel data

This study investigates whether the family income level in early life influences the financial independence of young adults. Using a large nationally representative U.S. sample (constructed based on the data from the 1999 to 2015 Panel Study of Income Dynamics, its 2009 to 2015 Transition to Adulthood Supplement and its 1997 to 2007 Child Development Supplement), we find that the relationship between one's family income level during adolescence and the financial independence of young adults follows an inverted U‐shape. We find that the college graduation status plays an important role in determining the financial independence of young adults. Once young adults graduate from the college, their financial independence is no longer influenced by their family income level during adolescence. The results show similar patterns after controlling for cognitive and noncognitive abilities and financial behaviours of young adults when they were children or teenagers. The findings of this study have significant implications for policymakers and educators.     

The Doctrine of the Mean: Workplace Relationships and Turnover Intention

The present study examines the curvilinear relationships between LMX/TMX and team members' turnover intention simultaneously. That is, members with high LMX, TMX, or both are more likely to have turnover intention. Hypotheses were tested with a sample of 452 nurses, and we adopted the response surface methodology and polynomial regression to test our theoretical model. The hierarchical regression analysis showed that TMX has a U‐shaped relationship with turnover intention but not with LMX. In addition, the results indicate that both the congruence and incongruence of LMX and TMX result in higher turnover intention, but moderate levels of LMX and TMX have the lowest turnover intention. Strengths, limitations, practical implications, and directions for future research are discussed. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.     

高校科研团队知识隐匿研究——基于知识共享激励视角

基于对中国高校科研团队的实地调研和考察,结合激励理论、社会偏好理论、互惠理论以及公平理论等多种理论,从激励的视角研究了知识隐匿与知识共享之间关系及其调节作用.文章运用投影寻踪法和层次回归分析法开展实证研究,研究发现:高校科研团队知识隐匿与知识共享自我效能呈现出显著的负相关关系,并且在考虑科研团队成员不同异质性的条件下,这一负相关关系具有高度的稳健性.在考虑到激励因子时,内部激励具有比外部激励更强的激励效果,即内部激励更有利于高校科研团队的知识共享.在调节效应方面,总体而言,激励能够抑制高校科研团队的知识隐匿行为,增强高校团队成员之间的知识共享自我效能.     

"成渝双城" 与"一区两群"的交响

2021年10月20日,《成渝地区双城经济圈建设规划纲要》(以下简称《纲要》)发布. 这是一步关乎国家发展大局的关键落子.推动成渝地区双城经济圈建设,将有利于形成优势互补、高质量发展的区域经济布局,有利于拓展市场空间、优化和稳定产业链供应链,是构建以国内大循环为主体、国内国际双循环相互促进的新发展格局的一项重大举措.     

庚子赔款的债务化偿付及其影响

庚子赔款是中国近代史上最大一笔赔款,也是以长期债务形式体现的赔款。本文对庚子赔款的债务化偿付安排、利率水平、支付流程及经济影响等进行比较分析。发现:(1)庚子赔款本金4.5亿两,是清政府 1903 年财政收入的 4.33倍,但通过债务化偿付,每年支付赔款占财政收入比重逐步下降;(2)按购买力折算,庚子赔款本金约占1900年中国GDP的2.1%;(3)与当时主要国家长期债务利率相比,庚子赔款4%的利率属于中等水平;(4)将庚子赔款与德国“一战”赔款进行比较,发现赔款本金和占经济总量比重,中国低于德国,但中国每年支付赔款的财政压力高于德国;(5)庚子赔款偿付对近代中国的财税金融产生深刻影响,外籍海关税务司借机成为独立于中国政府的“第二财政”,外商银行藉此强化其“隐性中央银行” 地位,赔款还催生了货币流通的“新周期” 和“新危机”。总体上,赔款的债务化偿付安排不仅受政治外交形势主导,也与金融机构特别是银行跨国经营存在密切联系。赔款的经济影响不仅取决于偿付总量,也取决于经济治理能力和财税金融制度。国家财税金融制度落后,则受到冲击较大。     

自我监控人格对创新绩效的影响:基于社会信息处理理论

中国文化背景下,人们更容易表现出高自我监控特征,但目前对自我监控人格与创新绩效的研究还相对不足.基于社会信息处理理论,采用25家企业441个员工的调研数据,探究自我监控人格对创新绩效的影响机制.研究结果表明,自我监控人格对创新绩效存在显著驱动作用;组织创新氛围感知、员工个体创造力以"串联"结构在自我监控人格与创新绩效的关系间发挥链式中介作用.上述发现扩展了自我监控人格与创新绩效间作用路径,为企业管理人员正视员工自我监控人格以促进员工创新绩效提供了一定启示.     

Beyond symbolic and substantive: Strategic disclosure of corporate environmental information in China

Under increasing regulatory pressure to disclose environmental impacts, corporate environmental information disclosure (EID) is becoming more prevalent. However, the motives for EID and disclosure approaches (i.e., symbolic or substantive) remain controversial. Using a sample of data for 742 listed manufacturing firms in China across 3 years, we provide evidence to show that the level of EID is significantly positively associated with a firm's advertising intensity and that firms in moderately competitive industries have a higher propensity for adopting an EID‐based differentiated strategy than firms in stronger or weaker competitive industries. We also find that firms that are more sensitive to environmental issues strategically understate their environmental impact when directly facing consumers. Our results suggest that the implementation of corporate EID is strategic and that firms have strong market motives, even under regulatory pressure to demonstrate legitimacy. We discuss this study's contributions to research on EID theory and implications for strategic EID management.
