The COVID‐19 Pandemic and Families in Japan

This paper, which is authored by members of the Japanese Association of Family Therapy (JAFT), describes the COVID‐19 pandemic in Japan from a family systems perspective. The authors are active members of JAFT and include current and past presidents and officers. We describe the course of the pandemic and the ways in which government policies to mitigate the pandemic have affected Japanese families. Challenges that affect Japanese families include the inability to participate in family and social rituals, prescribed gender roles that specifically affect women, high suicide rates, and prejudice against those who are at risk of spreading the infection. The need to shelter in place has also forced family homes to function as a workplace for parents, classrooms for children, and day care services for frail elders, which has resulted in psychological distress among individuals and conflicts among families. We discuss ways that therapists have worked with Japanese families using online therapy.     

Who are the active and central actors in the ‘rising civil society’ in Mexico?

The debate about the rise of civil society in Mexico suggests that the processes of political and economic liberalization are multiple and uneven and, thus, have different and contradictory effects on different social groups. This study takes such arguments into account and examines the nature of collective identities and social networks that are more likely to be mobilized in the rising civil society. Who, with what types of social networks and identities, are the active actors in this rising civil society in Mexico? This study also attempts to identify the central actors who take an active part in multi-sector coalitions. As such a broad coalition often leaves profound effects on politics and society, it is vital to ask which actors are likely to take an important step toward multi-sector coalition making. Using a catalog of 1797 protest campaigns collected from three Mexican newspapers between 1964 and 2000, event frequency analysis is employed to find active actors and social network analysis – blockmodel method and degree centrality measure – is applied to uncover central actors. The analyses reveal that while workers, peasants, or students continue to be very active, the centrality of these actors in contentious networks and coalitions has not increased. New central actors in the rising civil society turn out to be civic associations and NGOs formed around single issues, such as environment, retirement, and human rights. When a multi-sector coalition occurs in contemporary Mexico, NGOs and civic associations are likely to play a crucial role in it.     

Asymptotic distribution of regression correlation coefficient for Poisson regression model

This study treats an asymptotic distribution for measures of predictive power for generalized linear models (GLMs). We focus on the regression correlation coefficient (RCC) that is one of the measures of predictive power. The RCC, proposed by Zheng and Agresti is a population value and a generalization of the population value for the coefficient of determination. Therefore, the RCC is easy to interpret and familiar. Recently, Takahashi and Kurosawa provided an explicit form of the RCC and proposed a new RCC estimator for a Poisson regression model. They also showed the validity of the new estimator compared with other estimators. This study discusses the new statistical properties of the RCC for the Poisson regression model. Furthermore, we show an asymptotic normality of the RCC estimator.     

Constitutions and Public Support for Welfare Policies*

Objectives. This research explores how constitutional designs affect a cross‐national gap in public support for welfare policies. We contend that the constitution's statements regarding the citizens' right to receive welfare services constrain elite discourse on social welfare, which in turn exerts a strong influence on the level of mass support for and ambivalence over welfare policies. Methods. Survey data from 15 consolidated democracies merged with country‐level data are analyzed using a hierarchical linear model. Results. Empirical analysis shows that citizens residing in countries with a more liberal constitution show more supportive and less ambivalent attitudes toward welfare policies. Conclusions. Our findings suggest that the political principles reflected in national constitutions explain the cross‐national gap in mass support for welfare policies.     

Effects of Risk Representation and Scope on Willingness to Pay for Reduced Risks: Evidence from Tokyo Bay, Japan

When applying the contingent valuation method (CVM) in risk reduction studies, some studies report that willingness to pay (WTP) is insensitive to the magnitude of risk reduction while other studies do not. On the other hand, social-psychological research has shown that the affect heuristic biases judgments on probability, relative frequency, and risk. This article examines both magnitude (or scope) effect and affect heuristic (or representation) effect on WTP for risk reduction measures against tsunamis by introducing two experimental (i.e., absolute and relative) systems with four different representations to evaluate public behaviors in two different scenarios of risk reduction. Two common denominators (100 and 10,000) are introduced into absolute risk reduction representation (i.e., "of every 100 persons, from present 2 deaths to 1") to form different formats (i.e., "of every 10,000 persons from 200 to 100," and "of every 100,000 persons from 2,000 deaths to 1,000"). There is little evidence that WTP estimates are sufficiently sensitive to the magnitude of risk reduction, but relative risk reduction representations may be better than the absolute one given in CVM mail surveys when the risk is small. There is a statistically insignificant effect of risk reduction representations on respondent frequency, but mixed effects on the monetary values of WTP at the level of 0.05. The representation effect of absolute risk reduction on the WTP value varies with the common denominator. The larger the common denominator, the less the WTP to reduce the risk of tsunamis, and the significance probability is improved to less than the level of 0.05 when the common denominator becomes large enough. The findings suggest that improved methods are required for estimating the rates of tradeoff between fatality risk and other goods among consumers.     

Note on social choice allocation in exchange economies with Cobb–Douglas preferences

We show that in a pure exchange economy with two agents and a finite number of goods, there exists no strategy-proof, Pareto-efficient, and non-dictatorial social choice allocation function on any local Cobb–Douglas preference domain. This is a slight extension of a result proved by Hashimoto (2008).     

论《雪国》中女性的哀切观照

《雪国》赞扬“女性的生命”,艺伎被塑造成清洁美人,并有着良好的审美情趣。驹子不是一个积极的行动者,而是一个映入有怜悯之心的受众眼中的女子,她没有近代特色的自我,她对岛村的爱再炽烈,也还是一个古典女性。就女性的爱而言,川端有着无际的梦。他笔下的男主人公往往从女主人公那里得到了更深的爱。驹子向具有纯粹感性的率真者投注了生命,她明知这一切是徒劳的,却依然热衷于“无偿”行为。川端认为,驹子越是如此,越能提高关的纯度。《雪国》利用这种美的力学,吸引了读者。川端将美的力学引至优美纤细、充满生命力的感动之中,构造出洗练的唯美世界。     

Estimate of the Number of International Children in Japan, Based on Trends in Intermarriage

Abstract  This paper focuses on international children (that is, children whose parents have different nationalities) in Japanese society. Using statistics on intermarriage in Japan between 1965 and 1990, we project the numbers of such children from 1991 to 2000. The important findings are summarized below:
1. There were estimated 165,000 international children under the age of 21 in Japan as of 1991. The number will increase to 528,000 by the end of the century if the intermarriage rate continues to increase as it has recently, but this will still represent less than 2% of the Japanese population under 21.
2. By the year 2000 roughly 75% of these will be children of foreign mothers, due to the rapid increase in marriages between Japanese grooms and foreign brides.
3. The number of children with dual nationality continues to remain much lower in Japan than advanced countries in Europe, despite concern expressed when the Nationality Law was revised in 1985. The number of children born to international couples in Japan is surprisingly small with respect to the number of international marriages, so a dramatic increase is not likely.     

Critical review and comparison of continuity correction methods: The normal approximation to the binomial distribution

We provide a comprehensive and critical review of Yates’ continuity correction for the normal approximation to the binomial distribution, in particular emphasizing its poor ability to approximate extreme tail probabilities. As an alternative method, we also review Cressie's finely tuned continuity correction. In addition, we demonstrate how Yates’ continuity correction is used to improve the coverage probability of binomial confidence limits, and propose new confidence limits by applying Cressie's continuity correction. These continuity correction methods are numerically compared and illustrated by data examples arising from industry and medicine.
