Managing lean capabilities through flexible workforce development: a process and framework

Many firms today are employing temporary contractual workers in order to help them to stay lean and flexible. The benefit of this approach is that the process of layoff is much easier. Thus, an emerging issue arises here, on how can firms manage and train temporary workers effectively? The core of lean adoption is through people, to have workers buy into the ideas and be part of the overall initiative. There is very little guidance available on how to deal with contractual workers who have less motivation and commitment to the firm given that they are only employed on a temporary basis. This article proposes a framework and process to assist firms in managing and training temporary workers to improve the efficiency and effectiveness of the implementation of lean improvement initiatives.     

Influence of alliance portfolio diversity on innovation performance: the role of internal capabilities of value creation

In this study, we suggest a new perspective on the linkage between alliance portfolio diversity and innovation performance based on a contingency approach. Using a longitudinal data set on alliance portfolios and patents of 182 firms in the U.S. manufacturing industries, we examined that alliance portfolio diversity has a U-shaped relationship with firm-level innovation. Internal value creation capabilities in terms of routine and ability are found to moderate the relationship between alliance portfolio diversity and innovation performance: organizational search routine strengthens the relationship of alliance portfolio diversity and innovation performance while technological capabilities weaken and flip the relationship.

     

Developmental Trajectories and Predictors of Social Exclusion Among Older Koreans: Exploring the Multidimensional Nature of Social Exclusion

The purpose of this paper was to investigate the developmental patterns of social exclusion among older Koreans over time. In addition, we identified the significant determinants that may increase the risk of social exclusion among older Koreans. The analyses were based on the panel data from the Korean Longitudinal Study of Ageing and included older adults from 2008 to 2012 (N?=?24,074) for the final analysis. Social exclusion was categorized into four different sub-dimensions: financial, social relational, social cultural, and emotional. The analysis was based on a semi-parametric group-based approach followed by multinomial logistic regression. The results showed considerable variations and different developmental trajectories by the social exclusion sub-dimensions among older Koreans; in particular, the results showed that being older, male, and less educated were significant indicators of social exclusion. This study adds to the limited body of literature on longitudinal studies of social exclusion among older Koreans, and the results will help develop interventions for older Koreans who are socially isolated.

     

Social work in the making: The state and social work development in China

The instrumental role of government in the development of social work in China has led to questions about its political function. So far, little has been reported on how the government has “made” social work in China. To fill this gap, we first provide a brief chronological review of major policies and activities of the Chinese government in its making of social work in China. The state's intervention has indeed been massive and crucial although, politically, it may limit the mandate of social work in China. Yet, we argue that the development of the social work profession in China is generating institutional space for the emerging civil society to take a more active role in welfare service delivery. Situated and mediating between the state and the emerging civil society, the social work profession in China will need to constantly negotiate its mandate to meet the needs of both sides.     

Determinants of fertility control in Korea

The objective of this study is to examine the socioeconomic and intervening determinants of fertility control in Korea. The conceptual framework applied here is based on the synthesis framework of fertility control developed by Easterlin and Crimmins. The data came from the 1974 Korean National Family Survey, which was conducted as part of the World Fertility Survey. The study focuses on the relative importance of the socioeconomic factors and intervening variables in the determination of fertility control. The most interesting finding is that there are only small differentials in fertility control by socioeconomic factors. The analysis emphasizes the importance of examining the determinants of fertility control in terms of the intervening variables, which include the components of natural fertility, desired family size, and costs of fertility control. These intervening variables provide general support for the theoretical predictions. Moreover, most of the coefficients for these variables are statistically significant at the .05 level. The analysis also shows that motivation for fertility control is an important factor in determining use of fertility control.     

Family structure and educational attainment of children: effects of remarriage

This study explores how remarriage alters the effect of living in a female-headed family on children's educational attainment. The analysis is based upon data from a mother/child extract taken from the 1984 March/April Match file of the Current Population Survey. Ordinary least squares regression analysis and logit analysis are used. The results are mixed. While remarriage mitigates the negative effects of single-parent family living on years of school completed and the probability of high school graduation, it exacerbates these effects on the probability of entering college by ages 18–20 years, especially for boys. Thus, while remarriage increases income and reduces time pressures compared to single-parent family living, the presence of a stepfather appears to complicate the college entrance decision.This research is based upon the Ph. D. thesis of Seung Sin Chung, submitted to the School of Human Resources and Family Studies at the University of Illinois at Urbana-Champaign. We are grateful to John W. Graham for considerable effort in preparation of the data extract for this research as well as for comments, to Sara McLanahan for useful discussion, to John Boyd for excellent programming assistance, and to Se-jeong Yang and Yang-Suk Kim for able research assistance.

MONEY TRANSFER AND BIRTH WEIGHT: EVIDENCE FROM THE ALASKA PERMANENT FUND DIVIDEND

The positive relationship between income and health is well established. However, the direction of causality remains unclear: do economic resources influence health, or vice versa? Exploiting a new source of exogenous income variation, this study examines the impact of the Alaska Permanent Fund Dividend (APFD) on newborns' health outcomes. The results show that income has a significantly positive, but modest effect on birth weight. We find that an additional $1,000 ($2,331 in 2011 dollars) increases birth weight by 17.7 g and substantially decreases the likelihood of a low birth weight (a decrease of around 14% of the sample mean). Furthermore, the income effect is higher for less‐educated mothers. Based on a gestation‐weight profile in the sample, increased gestation owing to the APFD could explain a maximum of 34%–57% of the measured weight increase, although we are unable to examine all the potential mechanisms.

Prevalence of Sexual Dysfunction and Associated Risk Factors in Middle-Aged and Elderly Korean Men in Primary Care

Although several studies have individually investigated the risk factors for erectile dysfunction (ED), premature ejaculation (PE), and late-onset hypogonadism (LOH), few studies have considered ED, PE, and LOH as categories of sexual dysfunction (SD) within the same population. We therefore aimed to investigate the prevalence of SD and its associated risk factors among men in primary care. Study participants were enrolled by 18 family physicians from 15 hospital-based family practices in Korea between August 2010 and May 2011. Participants answered a questionnaire regarding their demographic characteristics and lifestyle factors as well as the Korean versions of the Androgen Deficiency in the Aging Male, the International Index of Erectile Function, and the Premature Ejaculation Diagnostic Tool questionnaires. SD prevalence was 64.9% among study participants who were ≥ 40 years of age. ED prevalence was 43.7%, PE prevalence was 38.6%, and LOH prevalence was 16.8%. SD prevalence was significantly associated with increased age, overweight, hypertension, diabetes, and depression. These findings highlight the importance of screening questions for SD in primary care, especially among older male patients with the identified risk factors.     

Evidence for an Incipient Decline in Numbers of Missing Girls in China and India

The apparently inexorable rise in the proportion of “missing girls” in much of East and South Asia has attracted much attention among researchers and policymakers. An encouraging trend was suggested by the case of South Korea, where child sex ratios (males to females under age 5) were the highest in Asia but peaked in the mid‐1990s and normalized thereafter. Using census data, we examine whether similar trends have begun to manifest themselves in the two most populous countries of this region, China and India. The data indicate that child sex ratios are peaking in these countries, and in many subnational regions are beginning to trend toward lower, more normal values. This suggests that, with continuing economic and social development and vigorous public policy efforts to reduce son preference, the “missing girls” phenomenon could eventually disappear in Asia.
