战后日本农户结构的变化及其影响

战后,随着日本经济的高速发展,农业生产机械化、集约化及产业化也迅速发展,使农业生产效率得到很大的提高,由此导致日本农户结构发生了很大的变化.主要表现为农户数目大量减少、农业劳动力数量萎缩及老龄化、兼业农户比重迅速增加等.农户结构的变化对日本农协的组织产生了深刻影响.

Profitability measurement of UK theme parks: an aggregate approach

Traditionally, financial ratios were used for profitability measurement. This research attempts to apply data envelopment analysis (DEA) to aggregate various financial ratios into a composite profitability index. The research sample includes 13 parks managed by 10 leading theme park operators in the UK. The result first reveals that multi‐site operators are significantly more profitable than their single‐site rivals. Furthermore, the consistency between DEA and ratio analysis indicates that DEA can be used as a good proxy of ratio analysis. It is hoped that this approach can provide new insights about financial measurement not available to managers through ratio analysis. Copyright © 2008 John Wiley & Sons, Ltd.     

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。     

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.
