This paper examines whether overconfidence can explain the relationship between performance and behavior of investors in Taiwan. Different from prior research that used a specific sample of individuals trading records, this work focuses on aggregate investor behavior to know whether overconfidence is a market-wide phenomenon. It is found that overconfident investors will trade more aggressively, and the excessive trading of overconfident investors results in the observed excessive market volatility. However, overconfidence effect exists only following bull markets. After a period of stock gains, overconfident traders tend to title their investment toward smaller-cap and growth stocks, consistent with the prediction of overconfident hypothesis that as investors become overconfident, they underestimate risk and thereby trade in riskier stocks.

Phenylketonuria (PKU) is a treatable and preventable inherited metabolic disease. The overall incidence of PKU in China is 1/11,144. Newborn screening is an effective method of controlling PKU. In1981, the Chinese Government initiated a newborn screening program and the number of newborns screened for PKU in China has risen each year. This review describes the current status of laws and regulations related to newborn screening for PKU in China and it identifies how China's newborn screening program has improved as a result of these laws and regulations. Specific measures and regulations, such as those implemented by government, follow-up services, and government coverage of expenses, have been implemented in different areas where they have yielded good results. These measures and regulations may serve as a reference for other areas of China. However, measures and regulations regarding newborn screening in China still face challenges. Prenatal health examinations and national financial support are expected to play a more significant role in newborn screening for PKU in the future.

This study examined interview accounts from thirty-one Taiwanese older adults about their inter- and intra-generational communication experiences, and perceptions of today's young and older people. Thematic analysis showed that Taiwanese older adults tended to initiate conversation topics accommodative to young people's lives such as their job and marriage, whereas conversation topics with their old-age peers centered on adjustment into senior years (e.g., health, exercise) and their children's achievement. Analysis also revealed some of the Taiwanese older adults' major perceptions of young people (e.g., less respectful towards elders) and their peers (e.g., losing status in the family). The discursive strategies used in constructing such perceptions (e.g., discourse on self exception, denial of self inclusion) demonstrated the ways in which they negotiated and managed their age identity in inter- and intra-generational communication. Results are discussed in light of Social Identity Theory, Communication Accommodation Theory, age identity, filial piety, and cultural change.
