Trajectories of Community-Based Service Use: The Importance of Poverty and Living Arrangements

ABSTRACT

This study examined how older adults’ living arrangements and poverty status affected their use of in-home health, functional, and out-of-home services over time. Using eight waves of data from the Korea Welfare Panel Study, we employed a logistic mixed-effect model to analyze how poverty and living arrangements affect community-based service use. Living-alone older adults and elder-only couples were more likely than co-residing households to use services. Elder-only couples, when poor, were more likely to use in-home and out-of-home services over time. Understanding predictors of community-based service use over time enables researchers and policymakers to better understand the process of aging-in-place.     

Transnational Corporate Elites in Japan: International Career Mobility in East and South Asia

Although mainstream globalization literature has attempted to provide an empirical proof of the rise of transnational business elites using several indicators, it is still not clear how to pinpoint transnationality and to establish whether globalization has led to the erosion of nation‐state boundaries through worldwide mobility and networks, as globalization theorists argue. Using empirical data on career paths and mobility over three decades in Japan – compared with other East Asia economies and India – we examine the shift in career mobility. First, we maintain that a comprehensive understanding of social, political and cultural dimensions need to be considered in a discussion of transnationality. Second, we suggest that the globalizing economy does not necessarily lead to the weakening of the nation‐state territory and its institutions in all sociocultural and political dimensions. In particular, transnationality in career mobility in Asian economies is not greatly evident. We propose instead that a new career pattern, which we call brain circulation, highlighting the importance of international experience, has emerged.     

Adaptive Sequential Preventive Maintenance Policy and Bayesian Consideration

This article proposes an adaptive sequential preventive maintenance (PM) policy for which an improvement factor is newly introduced to measure the PM effect at each PM. For this model, the PM actions are conducted at different time intervals so that an adaptive method needs to be utilized to determine the optimal PM times minimizing the expected cost rate per unit time. At each PM, the hazard rate is reduced by an amount affected by the improvement factor which depends on the number of PM's preceding the current one. We derive mathematical formulas to evaluate the expected cost rate per unit time by incorporating the PM cost, repair cost, and replacement cost. Assuming that the failure times follow a Weibull distribution, we propose an optimal sequential PM policy by minimizing the expected cost rate. Furthermore, we consider Bayesian aspects for the sequential PM policy to discuss its optimality. The effect of some parameters and the functional forms of improvement factor on the optimal PM policy is measured numerically by sensibility analysis and some numerical examples are presented for illustrative purposes.     

Graphical evaluation of robust parameter designs based on extended scaled prediction variance and extended spherical average prediction variance

For any response surface design, there are locations in the design region where responses are estimated well and locations where estimation is relatively poor. Consequently, graphical evaluation—such as variance dispersion graphs and the fraction of design space—is used as an alternative to a single-valued criterion. Such plots are used to investigate and compare the prediction capabilities of certain response surface designs currently available to the researcher. In this article, we propose the extended scaled prediction variance and extended spherical average prediction variance as prediction methods. We also illustrate how graphical methods can be employed to evaluate robust parameter designs.     

Introduction: social policy and economic development in late industrializers

This Supplement in the International Journal of Social Welfare presents the main findings of a United Nations Research Institute for Social Development research project on social policy in late industrializers, covering countries in East Asia, Latin America, Middle East and North Africa (MENA), and sub-Saharan Africa, as well as the Nordic countries. One of the findings from the research is that social policy has been used as an integral part of economic development in successful late-industrializing countries. In the MENA region and sub-Saharan Africa, however, social policy was tried for too short a period to be properly implemented and tested. East Asian and Latin American countries started with a narrow-based social policy, but social policy in East Asia was extended to foster social solidarity, bringing people into the mainstream of social change. Such findings suggest that social policy is multifunctional, not only in terms of social protection but also economic development and democratic governance.     

Inadequate Policy or Operational Failure? The Potential Crisis of the Korean National Pension Programme

The Korean National Pension Programme is one of the main pillars of the Korean welfare state. From its introduction in 1988, the Programme had come to include 26.8 per cent of the economically active population and had accumulated a pension fund equal to 24 per cent of government expenditure by 1994. Behind such a promising facade, the Korean National Pension Programme is likely to face financial crisis without a major reform. This paper seeks to answer the question as to whether the crisis will arise due to inadequate policy design or to operational failure. The latter cause may require privatizing the Pension Fund in order to operate more efficiently, while the former one would demand rectifying the defects of policy design. This study argues that the crisis is strongly related to inadequate policy design, which promises generous pensions and at the same time requires only a small amount in contributions; although there have also been operational inefficiencies in running the programme. It also argues that inadequacy in policy design stemmed from developmentalism embedded in the Korean welfare state, which regards the National Pension Programme mainly as a measure for mobilizing cheap capital. In conclusion, this paper argues that the Korean welfare state, created in the era of economic development, is transient in nature and that it needs a major reform not only to contain the cost but also to meet the growing demand for social welfare.     

Policy learning and cross-national diffusion in social long-term care insurance: Germany, Japan, and the Republic of Korea

Recently, many developed countries have moved toward comprehensive Long-Term Care (LTC) systems. Along with the conventional explanations of these policy changes based on domestic factors, learning from abroad should be considered. We focus on the social insurance model of LTC, particularly how Japan learned from Germany and the Republic of Korea learned from Japan. Some approaches for how to think about policy learning in general as well as cross-border learning are suggested.     

Inference on the ratio of two coefficients of variation of two lognormal distributions

The coefficient of variation (CV) can be used as an index of reliability of measurement. The lognormal distribution has been applied to fit data in many fields. We developed approximate interval estimation of the ratio of two coefficients of variation (CsV) for lognormal distributions by using the Wald-type, Fieller-type, log methods, and method of variance estimates recovery (MOVER). The simulation studies show that empirical coverage rates of the methods are satisfactorily close to a nominal coverage rate for medium sample sizes.
