Estimation of the scale parameter of the half-logistic distribution with multiply type II censored sample

In this paper, we consider the maximum likelihood and Bayes estimation of the scale parameter of the half-logistic distribution based on a multiply type II censored sample. However, the maximum likelihood estimator(MLE) and Bayes estimator do not exist in an explicit form for the scale parameter. We consider a simple method of deriving an explicit estimator by approximating the likelihood function and discuss the asymptotic variances of MLE and approximate MLE. Also, an approximation based on the Laplace approximation (Tierney & Kadane, 1986) is used to obtain the Bayes estimator. In order to compare the MLE, approximate MLE and Bayes estimates of the scale parameter, Monte Carlo simulation is used.     

The Role of Internal Health Locus of Control in Relation to Self-Rated Health in Older Adults

ABSTRACT

The present study examined how internal health locus of control is associated with older adults’ self-rated health. Multivariate analyses with older participants (aged ≥ 60) in the MIDUS II (n = 1,533) showed that internal health locus of control was not only directly associated with positive ratings of health but also interacted with gender and race. The positive impact of internal health locus of control on self-rated health was particularly greater in females and Whites than their counterparts. Findings highlight the important role of internal health locus of control in the psychological mechanism of health and call attention to group-specific strategies for health promotion.     

Race,Ethnicity, and Deviance: A Study of Asian and Non-Asian Adolescents in America

This study shows that Asian American adolescents commit less deviance in the form of school misbehavior than white, black, Hispanic, or Native American adolescents. Social control and social learning theories receive support as the observed differences are explained primarily by race/ethnic differences in family backgrounds and school bonding. These variables' explanatory ability tends to be invariant across four regional groups of Asian Americans. This study applies OLS regression to self-reported data from a nationally representative sample.

Supplier Encroachment and Investment Spillovers

It is conventional wisdom that a manufacturer's encroachment into retail space will likely hurt an existing retailer. In contrast to this conventional belief, current research indicates that a retailer may welcome a manufacturer's encroachment despite the new competition in the final market. The encroachment may help the manufacturer have some “skin in the game” at the retail level, which will cause the manufacturer to make a selfish cost‐reducing investment that spills over to the retailer as a lower wholesale price. Such a spillover effect enhances the retailer's profit as long as the encroachment does not result in extreme retail competition by a certain degree of product differentiation, and ultimately generates Pareto gains in the supply chain. The spillover effect is so robust that the retailer's benefit from the encroachment remains even after considering potential mitigating factors such as selling costs, a nonlinear form of cost reduction, decentralized encroachment, additional retail competition, price competition, and a negotiation between the manufacturer and the retailer.

Stepping‐Stone to Intergenerational Mobility? The Springboard,Safety Net,or Mobility Trap Functions of Korean Immigrant Entrepreneurship for the Second Generation1

Much research has viewed immigrant entrepreneurship positively because of its reputed role in immigrant economic adaptation. With the growing professionalization of children of Korean immigrant proprietors, small business ownership is seen as a stepping‐stone to intergenerational mobility. To assess whether immigrant entrepreneurship serves as springboard to upward mobility for the second generation, this article compares the educational and occupational achievements between children of entrepreneurs and children of professionals. The comparisons reveal that a higher proportion of children of professionals attended selective colleges, obtained professional occupations, and earned competitive salaries. Results from multiple regression analyses also indicate that entrepreneurship was not a good predictor of college selectivity and earnings for the second generation. Nevertheless, children of entrepreneurs attained comparable educational and occupational achievements as those of children of professionals, suggesting that rapid financial security through entrepreneurship can replicate similar residential and educational opportunities for children of entrepreneurs. While the springboard and safety net functions of small business on intergenerational mobility are salient, in some circumstances, obligations to help out in a family business can lead to personal sacrifice on the part of children of entrepreneurs, constraining their educational and occupational choices and leading some toward downward mobility.     

Cultural Identity,Social Capital,and Social Control of Young Korean Americans: Extending the Theory of Intercultural Public Relations

Through 10 in-depth interviews and 2 focus groups, this exploratory study examines how young Korean Americans perceive cultural identity, utilize social capital, and identify conflicts that arise between themselves and their significant others, particularly focusing on how they integrate Korean and American culture. The findings reveal that young Korean Americans have multifaceted, situational identities, which go beyond existing cultural stereotypes, maximize their religious-based social capital and human capital, and experience a varying range of cultural tensions and conflicts in social settings. Therefore, situational cultural identity, a new category of intercultural public relations is suggested, and implications for the practice of public relations are discussed.
