Colonial legacy of ethno-racial inequality in Japan

This essay challenges anti-historicist accounts that sever the link between the colonial past and present, replacing them with a more historically nuanced understanding of Japan’s immigration policies and their relation to ethno-racial inequality. Contrary to the dominant view that transnational immigration is new to Japan, this article shows that Japan already had a history of immigration in the early twentieth century, and this history generated a lasting impact on postwar immigration policies and their integration. While recognizing the impact of structural and individual factors, this essay underscores a path-dependent approach that demonstrates how colonial exclusion led to the formation of a durable structure of inequality against low skilled labor immigrants, and thus how such a colonial legacy has continued to limit the life chances and integration of subsequent immigrants in Japan since the 1980s.     

A note on nonlinear regression for the autoregressive moving average with non-hd errors

Estimation by nonlinear regression of the parameters for the stationary and invertible autoregressive moving average (ARMA) model with mixing or martingale difference errors is considered. Simple proofs of consistency and asymptotic normality for the nonlinear least squares estimator are given by exploiting results from nonlinear estimation theory and mixing and mixingale theory.     

Optimal consumption and portfolio selection with negative wealth constraints,subsistence consumption constraints,and CARA utility

We consider the optimal consumption and portfolio selection problem with constant absolute risk aversion (CARA) utility. The economic agent in this model receives constant labor income, and her economic behavior is restricted on consumption and wealth, which are called the subsistence consumption constraint and the negative wealth constraint. We use the convex duality method to derive the value function and the optimal policies in closed-form solutions. Also we illustrate some numerical examples.     

Precarious work: A global perspective

Precarious work is universal, though its forms and consequences vary across countries due to institutional, cultural, and historical differences. This article reviews recent research on precarious work from a global perspective, emphasizing the comparative and interdisciplinary research needed for a comprehensive understanding of the structural transformations in contemporary capitalism that promote precarious work. The article has three foci. First, research that details the diverse forms of precarious work, which have become increasingly heterogeneous as national labor markets have been interwoven with global production networks. Second, research on precarious work that emphasizes its disparate impacts for women, youth, the elderly, racial and ethnic minority groups, and migrants, revealing an articulation of precarity and social cleavages. Third, research on the politics associated with precarious work and how some precarious workers have successfully organized and mobilized their interests, such as by unionizing and becoming involved in electoral politics. Still, questions remain regarding precarious work: how precarious workers differ from regular workers in representing their interests and demands and whether precarious workers are a new, independent social class or remain part of a changing working class. Finally, topics for future research on the global dimensions of precarious work are discussed.     

Self-perception of aging and health among older adults in Korea

The way that each individual perceives his or her own aging and health may be a key indicator of adaptation and well-being in old age. This study explored the determinants of self-perception of aging and health using 291 community-dwelling older adults in Korea (mean AGE=69.9). Older individuals with lower levels of education and economic status and various types of health problems (more chronic conditions, greater disability, poorer vision, and greater numbers of sick days) were found to have more negative self-perception of aging and health. In addition, a significant role of psychological factors was observed. For self-perception of health, sense of mastery was found to be a significant factor, and for self-perception of aging, neuroticism was observed to be significant along with sense of mastery. The mediating role of self-perception of health was supported that positive perception of health intervened the adverse effects of health problems on self-perception of aging. The findings demonstrate the important roles of psychological resources and subjective perceptions and suggest a need to consider them when planning interventions.     

Social Policy in South Korea: Cultural and Structural Factors in the Emergence of Welfare

There are a number of features that make South Korea an interesting place to study social policy. First, it has experienced rapid economic development with the associated changes in urbanization and demography. This change has created social problems, which the state has had to address. Second, the country retains a strong cultural tradition and repeated affirmation of the values and practices of Confucianism. In this paper, these two features are considered in relation to the way social policy has been addressed. The thrust of the paper will be on the policy responses to perceived social problems and the way in which other social problems are individualized within families. These policies are informed and shaped by Korean politics and culture.     

Kullback–Leibler information of a censored variable and its applications

In this paper, we study the Kullback–Leibler (KL) information of a censored variable, which we will simply call it censored KL information. The censored KL information is shown to have the necessary monotonicity property in addition to inherent properties of nonnegativity and characterization. We also present a representation of the censored KL information in terms of the relative risk and study its relation with the Fisher information in censored data. Finally, we evaluate the estimated censored KL information as a goodness-of-fit test statistic.     

Red states,blue states: How well do the recent national election labels capture state political and policy differences?

The alleged polarization between the so-called red (Republican) and blue (Democratic) states during the presidential elections has been examined using only voter surveys. Focusing on the recent thirteen national elections from 1964 to 2012, we examine social, political, institutional, and policy indicators of the 50 American states to (1) gauge the extent to which national election results reflect significant policy and political differences between the red and blue states and (2) to assess the explanatory power of the dichotomous red–blue label relative to a continuous variable of “redness” or “blueness” by the percentage of votes received. We find substantial political and some moderate social differences between red and blue states but fewer institutional and policy differences than one would expect if there were actually deep divisions between the states. We find that the red–blue state distinction performs well when compared to the explanatory power of the more precise redness or blueness of a state.     

Cross‐Cultural Comparison of the Effects of Optimism,Intrinsic Motivation,and Family Relations on Vocational Identity

This study explored the effects of optimism, intrinsic motivation, and family relations on vocational identity in college students in the United States and South Korea. The results yielded support for the hypothesized multivariate model. Across both cultures, optimism was an important contributing factor to vocational identity, and intrinsic motivation partially mediated the link from optimism to vocational identity. In addition, family relations moderated the mediation effect of intrinsic motivation with American students but not Korean students. With Korean students, family relations moderated the direct link from optimism to vocational identity. These results have significant implications for counseling to promote vocational identity development for diverse college students.
