In addition, the results also revealed that among participants with high identification with the super-ordinate Chinese national group, this negative relation was significantly weaker than those with low Chinese identification.
Both technological decisions types influence organizational performance significantly and positive even though evidence shows a significant and negative relation between these decisions.
The relation with pairwise average habitat width was significantly negative (β = −0.096; P = 0.0048).
In the case of the unemployment rate, the negative sign of its coefficient appears to be consistent with the Phillips curve, which accounts for the negative relation between the inflation and unemployment rates.39 The significantly positive coefficient on the real ULC indicates the existence of a positive relation between developments in the price of labor and persistent developments in inflation.
There is a significantly positive relation between the unemployment rate (UER) and the proceeds ratio, and a negative relation between real GDP growth and the proceeds ratio.26 The direction of the macroeconomic influences is surprising at first glance.
The fact that elections took place in the previous year generally is linked with increased reform activity, significantly so for Early Withdrawal schemes and reforms in the Wage Setting system, while a significant negative relation is found for Labour Taxation.
Concerning the assumed relation between stress and problem-solving performance, hypothesis H3 can be confirmed for the significantly negative association between the LF/HF ratio and the problem-solving score.
While a significantly positive correlation between PD and annual mean precipitation was found in Inner Mongolia Plateau and Loess Plateau, a negative relation was found in Southeastern China and Southwestern China, and no obvious relationship found between them in Northeastern China, North China Plain, Middle and Lower Yangtze River Plain.
