Effect of fear of negative evaluation on excessive worry : An examination of modulation effect on cognitive control.

The purpose of this study was to examine the relationships among fear of negative evaluation, excessive worry (state and trait), refraining from catastrophic thinking skill, and logical analysis skill. A survey was administrated to 211 undergraduate students on fear of negative evaluation, excessive worry (state and trait), refraining from catastrophic thinking skill, and logical analysis skill. The analysis showed that refraining from catastrophic thinking may be able to moderate the effects between fear of negative evaluation and state worry. The analysis also showed that the people who are higher fear of negative evaluation, higher refraining from catastrophic thinking skill, and lower logical analysis skill, tend to get worth their trait worry. In conclusion, when we intervene for the people who are higher fear of negative evaluation, we should explain not only the way how to use refraining from catastrophic thinking skill, but also the way how to use logical analysis skill

Log-aesthetic Curves as Similarity Geometric Analogue of Euler's Elasticae

In this paper we consider the log-aesthetic curves and their generalization which are used in CAGD. We consider those curves under similarity geometry and characterize them as stationary integrable flow on plane curves which is governed by the Burgers equation. We propose a variational formulation of those curves whose Euler-Lagrange equation yields the stationary Burgers equation. Our result suggests that the log-aesthetic curves and their generalization can be regarded as the similarity geometric analogue of Euler's elasticae

Phenotypic variation of a new synthetic allotetraploid Arabidopsis

The phenotypic variation of vegetative organs and reproductive organs of newly synthesized and natural Arabidopsis kamchatica genotypes was investigated in both a controlled environment and a natural environment in an experimental garden. When we compared the variation of their leaf shape as a vegetative organ, the synthetic A. kamchatica individuals grown in the garden showed larger variation compared with the individuals incubated in a growth chamber, suggesting enhanced phenotypic variation in a natural fluctuating environment. In contrast, the natural A. kamchatica genotypes did not show significant change in variation by growth condition. The phenotypic variation of floral organs by growth condition was much smaller in both synthetic and natural A. kamchatica genotypes, and the difference in variation width between the growth chamber and the garden was not significant in each genotype as well as among genotypes. The higher phenotypic variation in synthetic leaf may imply flexible transcriptomic regulation of a newly synthesized polyploid compared with a natural polyploid
