Benzene Risk Estimation Using Radiation Equivalent Coefficients

We estimated benzene risk using a novel framework of risk assessment that employed the measurement of radiation dose equivalents to benzene metabolites and a PBPK model. The highest risks for 1 μg/m³ and 3.2 mg/m³ life time exposure of benzene estimated with a linear regression were 5.4 × 10⁻⁷ and 1.3 × 10⁻³, respectively. Even though these estimates were based on in vitro chromosome aberration test data, they were about one-sixth to one-fourteenth that from other studies and represent a fairly good estimate by using radiation equivalent coefficient as an "internal standard."     

Financial literacy and anxiety about life in old age: evidence from the USA

This study examines whether financial literacy can help to reduce anxiety about life in old age. We hypothesized that financially literate people are more able to earn income and accumulate assets, leading them to have a less anxious life in old age. On the other hand, less financially literate people rely more on social security to secure themselves in the old age as they are not able to accumulate sufficient assets. By using US survey data, we provide evidence that assets significantly reduce anxiety about life in old age only for people who are more financially literate. For less financially literate people, social security plays an important role in reducing anxiety about life in old age. Besides these, having a child and doing regular exercise also reduced anxiety for all respondents but marital status reduced anxiety in respondents over 40 years of age. The results of our study are robust to measurement of financial literacy and endogeneity problems.     

Cultural self-construction and identity formation in emerging adulthood: a study on Japanese university students and workers

Cultural pathways of identity formation have been largely unexplored. In many Asian cultures, youth are expected to concentrate on adaptation to their groups or relationships rather than pursuing their own uniqueness. Then, how do they develop a sense of identity while considering groups or relationships to be important? The purposes of this study were (a) to examine relationships between cultural self-construction (i.e. independence and interdependence) and identity processes (i.e. commitment, in-depth exploration, and reconsideration of commitment) in both societal and relational domains, and (b) to analyze the relationships of self-construction and identity processes with well-being, using a sample of Japanese emerging adults (i.e. university students and workers) aged 18–25 years. The findings indicated that relational identity was related to both independence and interdependence, whereas societal identity was mainly related to independence. Moreover, independence and identity in both societal and relational domains was positively related to well-being. Furthermore, the patterns of relationships among self-construction, identity, and well-being were found to be similar between university students and workers. These findings imply that while Japanese emerging adults have developmental needs to express one's own uniqueness, they are also directed to form a sense of identity emphasizing the maintenance of harmonious relationships with others.
