感悟瞬间突破传统——印象派画家莫奈浅谈

19世纪中后期，印象派画家放弃了注重形体而轻色彩的绘画观念，打破了传统绘画对色彩的束缚，运用当时先进的光学理论，发现在不同光线照射下景物丰富的色彩变化，留住瞬间印象，在绘画艺术上引起重大变革。莫奈是印象派最重要的代表，他以全新的视角，独特的表现光与色的手法，大胆创新的绘画语言，突破传统绘画题材进行创作，留下大量优秀作品令世人瞩目，成为“现代绘画的鼻祖”。     

The ‘miracle’ of car ownership in Japan's ‘Era of High Growth’, 1955–73

The ‘Era of High Growth’ in Japan is well known for its ‘miracle’ economy, although the reasons why car ownership increased during this period have been largely ignored. Both the ‘miracle’ and the process of motor manufacturing have been viewed from the perspective of supply rather than demand. This article examines the ways in which the formidable barriers to mass car ownership were removed during this period by analysing quantitative data and also reconsidering narratives of Japanese manufacturing predicated on Japanese cultural uniqueness (nihonjinron). It considers the Japanese as consumers as well as workers, and concludes that car ownership is less a ‘miracle’ than a manifestation of Japan's process of modernisation during the twentieth century.

Can traffic light nutritional labels induce healthier consumer choices? Experimental evidence from a developing country

In a context of increasing health problems related to bad dietary habits in developing countries, simplified nutritional label formats may be a promising policy alternative. The aim of this study is to assess whether the multiple traffic light (MTL) system can improve the nutritional quality of consumer decisions. We conducted a selection experiment in Peru, where participants were offered a choice between three alternatives in two different food categories (crackers and beverages). Individuals were randomly assigned products with MTL labels on them. Our results reveal that exposure to MTL labels significantly increases the probability of avoiding the least healthy options and of choosing the healthiest items among the alternatives provided. These effects are large in magnitude and seem to be driven by individuals that are female, report average or above average dietary habits, and lack basic nutritional knowledge. However, our findings also suggest that the effectiveness of MTL labels may be sensitive to the specific characteristics of the set of options provided. These findings contribute to the emerging experimental literature on MTL labels in two ways. First, we provide evidence that this system can be effective in inducing consumers to make healthier choices in real‐life situations. Second, we explore which individuals are more likely to benefit from exposure to MTL labels, as well as potential limitations to their effectiveness. Overall, our results provide new insights on how to assess the issue of bad nutrition in emerging economies.
