Effect of Participation of Foreign Migrant Workers in Labour Market on Native Workers: Evidence Based on Change Noticed in College Premium in Taiwan ROC

Using Manpower Utilization Survey data for 14 years from 1999 to 2012, we applied the DDDD (Differences–in–differences–in–differences–in–differences) estimation method to check if rising presence of foreign migrant workers in Taiwan’s domestic labour market had any impact on employment opportunities and wages earned by native Taiwanese workers over time. We used the data capturing the effect of college premium (viz., the additional cost to be borne for getting admission into college) paid by the natives on domestic wage rate during this period. College premium is an indicator of demand and supply for educated labour and we intend to see if the premium has grown with time when influx of foreign migrant workers has grown too. From the results, two interesting phenomena caught our attention. First, labour policy adopted by the Government in Taiwan has played an important role in increasing the influx of foreign workers into domestic labour market, which resulted in significant change in college premium paid by the natives. And, this effect lasted even when instances of strikes and reported cases of labour disputes were relatively higher. Second, the effect of the policy has been varying across genders as our data shows that policy on employment of foreign workers has affected job opportunities of native men workers more than it affected job opportunities of their female counterpart.     

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.     

A Note on a Framework for Valuation Ratios Based on Fundamentals*

Valuation ratios divide stock price by accounting metrics such as earnings, earnings growth, and book value. This study adapts the general valuation framework in Ohlson and Juettner-Nauroth (2005) and Ohlson (2005) to present a unified approach for developing valuation ratios based on fundamentals, referred to as fundamental valuation ratios. One starts with a valuation model that is driven by an accounting metric a and its abnormal growth, then divides the valuation model by a to get a fundamental valuation ratio. For any valuation ratio, one can find a corresponding fundamental valuation ratio, as long as the valuation model is based on the same metric a as the valuation ratio denominator.

微波加热对叶绿素水溶液的影响

本文通过对叶绿素水溶液进行微波加热,分析微波加热对叶绿素水溶液的温度、色度、叶绿素含量的影响。结果表明,微波加热处理的水溶液温度显著高于对照沸水浴,1~2 min时,1000 W功率下的水溶液温度显著高于200 W(P<0.05)。与沸水浴相比,微波加热显著降低了叶绿素水溶液的绿色程度,且高功率微波加热显著加剧了水溶液亮度的变化。200 W微波加热使水溶液中叶绿素a、b含量降低,但1000 W微波加热则提高了水溶液中叶绿素a、b含量。     

Training and organisational performance: A meta‐analysis of temporal,institutional and organisational context moderators

Drawing on systems theory, we conducted a moderated meta‐analysis of the training and organisational performance relationship using 119 primary studies. We examined the moderating effects of quality versus quantity of training, time, institutional and organisational context factors in the relationship between training and organisational performance. Our findings reveal that training is positively and directly related to organisational performance with no statistically significant difference between measures of training quality and quantity. We found that the relationship was stronger over time and that country performance orientation and country labour cost moderate the training and organisational performance relationship. We found no evidence for the moderating effects of the three organisational context moderators we examined (i.e. industry sector, organisational size and technology intensity). Finally, our results reveal that training type (i.e. general or firm‐specific) does not moderate the training and organisational performance relationship.     

京津冀城市群土地经济密度时空格局演变与驱动因素分析

[目的]研究2006—2016年京津冀城市群土地经济密度的时空格局演变特征及其驱动机制。[方法]以京津冀城市群153个县区为例,运用空间自相关分析、热点分析、地理探测器等研究方法,对土地经济密度的时空演变规律及其驱动因素进行探讨。[结果](1)2006—2016年京津冀城市群县区和地市的土地经济密度及其发展速度在空间上均呈"东高西低,南高北低"格局,但随时间变化区域差异逐渐缩小;(2)Moran′s I指数由0.013 9上升至0.065 3,表明在空间上存在空间集聚状态,且随时间不断优化,区域一体化趋势逐渐增强;(3)空间集聚特征明显,热点显著区集中于北京、天津等经济优势区,并向四周梯度扩散;(4)人均GDP、当年实际使用外资额、固定资产投资额等经济类因子对土地经济密度的解释力较大,且任意两因子交互后作用力优于单项因子作用力。[结论]可为京津冀城市群土地资源的合理利用和差别化调控提供参考。     

Potential Spatial Labor and Human Capital Mobility in China: Evidence from College Admissions Under the National College Entrance Examination System

Abstract:

Higher education in China plays an important role in promoting labor and human capital mobility. In this paper, I empirically address the issue of regional disparities, college admissions under the National College Entrance Examination (CEE) system, and potential interregional labor and human capital mobility in China. The results show that examinees from western provinces have a strong preference for coastal universities, compared with examinees from central provinces. College admissions in China then seem to have a stronger effect on potential labor and human capital movement from the western to the coastal regions than from the central to the coastal regions.
