Cheong: The Socioemotional Grammar of Koreans

Based on the replies of 36 Korean university students, we analyzed the structural properties that underpin the culture-bound concept of Cheong. Cheong embodies the emotional links among individuals connected to each other by feelings of we-ness and exhibiting the humanistic side of their selves. It is concluded that Western models of the nature of persons and of social relationships are insufficient to account for the socioemotional characteristics of Koreans.     

Geometry of the log-likelihood ratio statistic in misspecified models

We show that the asymptotic mean of the log-likelihood ratio in a misspecified model is a differential geometric quantity that is related to the exponential curvature of Efron (1978), Amari (1982), and the preferred point geometry of [Critchley et al., 1993] and [Critchley et al., 1994]. The mean is invariant with respect to reparameterization, which leads to the differential geometrical approach where coordinate-system invariant quantities like statistical curvatures play an important role. When models are misspecified, the likelihood ratios do not have the chi-squared asymptotic limit, and the asymptotic mean of the likelihood ratio depends on two geometric factors, the departure of models from exponential families (i.e. the exponential curvature) and the departure of embedding spaces from being totally flat in the sense of Critchley et al. (1994). As a special case, the mean becomes the mean of the usual chi-squared limit (i.e. the half of the degrees of freedom) when these two curvatures vanish. The effect of curvatures is shown in the non-nested hypothesis testing approach of Vuong (1989), and we correct the numerator of the test statistic with an estimated asymptotic mean of the log-likelihood ratio to improve the asymptotic approximation to the sampling distribution of the test statistic.     

A Reinvented Community: The Case of Gamcheon Culture Village

This study explores Gamcheon Culture Village in Busan, South Korea, as a special case of inclusive and participatory cultural-spatial transformation by which the village was transformed from an impoverished and decaying hillside slum into a vital and picturesque location and tourist attraction. The study delineates this process in terms of a distinctive engagement of the arts and cultural dynamics relative to general social well-being. Of particular note are the roles of resident activism and civil society, social entrepreneurs, and the arts and artists as key resources, all coming together in an organic redevelopment process. Evidence indicates an increased sense of community and cooperation, overall improvement in the quality of life, and cultural enrichment for the residents. However, transformation continues, and the sustainability of Gamcheon Culture Village as a successful case of redevelopment is dependent on the ongoing cooperation and participation of the resident base and primary artistic support.     

Accelerated failure time models for the analysis of competing risks

Competing risks are common in clinical cancer research, as patients are subject to multiple potential failure outcomes, such as death from the cancer itself or from complications arising from the disease. In the analysis of competing risks, several regression methods are available for the evaluation of the relationship between covariates and cause-specific failures, many of which are based on Cox’s proportional hazards model. Although a great deal of research has been conducted on estimating competing risks, less attention has been devoted to linear regression modeling, which is often referred to as the accelerated failure time (AFT) model in survival literature. In this article, we address the use and interpretation of linear regression analysis with regard to the competing risks problem. We introduce two types of AFT modeling framework, where the influence of a covariate can be evaluated in relation to either a cause-specific hazard function, referred to as cause-specific AFT (CS-AFT) modeling in this study, or the cumulative incidence function of a particular failure type, referred to as crude-risk AFT (CR-AFT) modeling. Simulation studies illustrate that, as in hazard-based competing risks analysis, these two models can produce substantially different effects, depending on the relationship between the covariates and both the failure type of principal interest and competing failure types. We apply the AFT methods to data from non-Hodgkin lymphoma patients, where the dataset is characterized by two competing events, disease relapse and death without relapse, and non-proportionality. We demonstrate how the data can be analyzed and interpreted, using linear competing risks regression models.     

Joint modeling of survival time and longitudinal outcomes with flexible random effects

Joint models with shared Gaussian random effects have been conventionally used in analysis of longitudinal outcome and survival endpoint in biomedical or public health research. However, misspecifying the normality assumption of random effects can lead to serious bias in parameter estimation and future prediction. In this paper, we study joint models of general longitudinal outcomes and survival endpoint but allow the underlying distribution of shared random effect to be completely unknown. For inference, we propose to use a mixture of Gaussian distributions as an approximation to this unknown distribution and adopt an Expectation–Maximization (EM) algorithm for computation. Either AIC and BIC criteria are adopted for selecting the number of mixtures. We demonstrate the proposed method via a number of simulation studies. We illustrate our approach with the data from the Carolina Head and Neck Cancer Study (CHANCE).

Poverty reduction effectiveness of public income transfers in South Korea in the wake of the global financial crises: a panel-data analysis

By using a longitudinal data-set from the Korean Labor and Income Panel Study, the present study examines the poverty reduction effectiveness of public income transfers in South Korea from 1998 to 2011. Findings indicate that the average poverty rate fell from over 20% between 1998 and 2000, to 14% from 2001 to 2006, rose to 17% by 2008, and declined to 15% in 2011. However, the poverty-rate reduction effectiveness continuously increased from 5.5% in 1998 to 32.8% in 2011. The poverty-gap reduction effectiveness also improved sixfold from 6.8 to 39.6% over the same period.     

Flow of Online Content from Production to Consumption in the Context of Globalization Theory

Some studies have regarded globalization as a process of cultural homogenization, while others see it as one of cultural heterogenization. This conflict stems from their focus on either the production or consumption side of cultural products based on globalization theories bifurcated into political economy and cultural studies. This study covers the production, distribution, and consumption sides in online content flow and examines the effects of economic, geographic, and linguistic factors. This question is explored through the study of longitudinal changes in the number of Internet hosts from 1995 to 2010, online network connectivity among 174 countries, and geographic distribution of the top 300 web domains. The results suggest that the economic factor was most likely to have an impact on the flow of online content from production to consumption, but that its impact weakened over time. In addition, geographic proximity accounted for the bilateral relationship between countries. Limitations of world-system theory are also discussed.     

Controlling Anxiety Mediates the Influence of Childhood Adversities on Risky Sexual Behaviors Among Emerging Adults

Relatively little research has assessed the exposure-response relationship of childhood adversities on engaging in risky sexual behaviors. Also, no previous research has examined the interrelationship among childhood adversities, adult anxiety and depressive symptoms, and risky sexual behaviors. This study aimed to investigate their interrelationships. We used data from a multisite survey of emerging adults aged 18 to 29 studying at four universities in Hong Kong between September and December 2015. Structural equation modeling (SEM) was used to examine the pathways from childhood adversities to risky sexual behaviors. Participants who had higher childhood adversity scores reported more severe adult anxiety symptoms (β = 0.20, p = 0.002); and adult anxiety symptoms were associated with significantly more risky sexual behaviors (β = 0.46, p < 0.0001). The model with adult anxiety symptoms as the mediator between childhood adversities and risky sexual behaviors showed good fit (root mean square error of approximation [RMSEA] = 0.04, comparative fit index [CFI] = 0.96, Tucker-Lewis index [TLI] = 0.94 and standardized root mean square residual [SRMSR] = 0.04). However, adult depressive symptoms failed to mediate between childhood adversities and risky sexual behaviors. This study demonstrates the link between childhood adversities and risky sexual behaviors via adult anxiety but not adult depressive symptoms. It is essential to reduce anxious symptoms in dealing with emerging adults who have risky sexual behaviors to prevent sexually transmitted infections (STIs) and unintended pregnancy.     

Mapping Japanese Imperialism onto Postcolonial Criticism

This article examines strategies of detachment and engagement in the ongoing struggles over defining a collective sense of ‘Israeli identity’ that take place in contemporary Israeli everyday discourse, and which is intended for insiders alone. The analysis compares material from two different samples of voluntary formulations of ‘how Israelis behave’ offered by anonymous Israelis in domestic public forums: one is a collection of about 300 folkloric aphorisms in a popular newspaper column, and the other includes over 1700 on-line talk-backs to 14 Internet reports about the bad reputation of Israelis abroad. These miscellaneous materials reveal a heated contest for the right to condemn a generalized collective image of ‘an Israeli person’. Mobilizing alternatively two value-paradigms, that of ‘European codes of civilized behaviour’ (an outside perspective) and that of ‘local patriotism’ (an inside perspective), a negative collective image of ‘misbehaved person’ is established, towards which conflicting group-attitudes are formed. Four main strategies are observed in disputing or confirming this negative image: a total personal alienation; patronizing engagement; a variety of denial tactics; and a provocative identification with ‘uncivilizedness’ as an ‘authentic Israeli mindset’.
