An Inside‐Out Marketing Strategy for Innovation among Human Service Nonprofits in South Korea

In the increasingly competitive nonprofit market, innovation may be the only choice for survival among human service nonprofits. Considering the importance of service encounters and high dependence on human resources, internal marketing has potential as a management strategy to improve innovative activities in human service nonprofits. To examine the effect of internal marketing strategy focusing on employees, this study investigates the mediating effect of customer orientation in the pathway from internal marketing to innovation. The findings from 258 community‐based social service centers in South Korea support the positive impact of internal marketing on customer orientation and innovation, although the significant evidence for the mediating effect of customer orientation is not found. The current study suggests implications for practice and future research.     

Causality in Contemporary American Sociology: An Empirical Assessment and Critique

Using a unique data set of causal usage drawn from research articles published between 2006–2008 in the American Journal of Sociology and American Sociological Review, this article offers an empirical assessment of causality in American sociology. Testing various aspects of what we consider the conventional wisdom on causality in the discipline, we find that (1) “variablistic” or “covering law” models are not the dominant way of making causal claims, (2) research methods affect but do not determine causal usage, and (3) the use of explicit causal language and the concept of “mechanisms” to make causal claims is limited. Instead, we find that metaphors and metaphoric reasoning are fundamental for causal claims‐making in the discipline. On this basis, we define three dominant causal types used in sociology today, which we label the Probabilistic, Initiating and Conditioning types. We theorize this outcome as demonstrating the primary role that cognitive models play in providing inference‐rich metaphors that allow sociologists to map causal relationships on to empirical processes.     

Those Who are Left Behind: An Estimate of the Number of Family Members of Suicide Victims in Japan

This paper contributes to the literature of suicide studies by presenting procedures and its estimates of the number of family members who lose their loved ones to suicide. Using Japanese aggregate level data, three main findings emerge: first, there are approximately five bereaved family members per suicide; second, in 2006, there were about 90,000 children who had lost a parent to suicide; and third, in 2006, there were about three million living family members who had lost a loved one to suicide. The direct production loss of bereaved family members in 2006 alone is estimated at approximately 197 million USD. These results are valuable in evaluating the cost-effectiveness of suicide prevention programs and in designing appropriate policy instruments.     

Social Isolation and Spousal Violence: Comparing Female Marriage Migrants With Local Women

This research examined the impact of network participation, social support, and social control on the violence victimization of female marriage migrants by a spouse. Data were from a household survey of 492 cross‐border and 379 local married couples in Hong Kong in 2007. The findings indicated that female marriage migrants were more vulnerable to spousal violence and more socially isolated, compared with local women. Husbands of marriage migrants were also more socially isolated compared with men who married locally. The network participation of both husband and wife was associated positively with spousal violence against women, whereas their perceived social control was associated negatively with violence. Female marriage migrants' greater vulnerability to spousal physical assault was a result of their younger age compared with local women, but their greater vulnerability to spousal psychological aggression and sexual coercion was related, in part, to their own and their husbands' network participation as well as their level of social control.     

High-dimensional Markowitz portfolio optimization problem: empirical comparison of covariance matrix estimators

We compare the performance of recently developed regularized covariance matrix estimators for Markowitz's portfolio optimization and of the minimum variance portfolio (MVP) problem in particular. We focus on seven estimators that are applied to the MVP problem in the literature; three regularize the eigenvalues of the sample covariance matrix, and the other four assume the sparsity of the true covariance matrix or its inverse. Comparisons are made with two sets of long-term S&P 500 stock return data that represent two extreme scenarios of active and passive management. The results show that the MVPs with sparse covariance estimators have high Sharpe ratios but that the naive diversification (also known as the ‘uniform (on market share) portfolio’) still performs well in terms of wealth growth.
