Defining Nations in Asia and Europe: A Comparative Analysis of Ethnic Return Migration Policy1

We argue that regional comparison of East Asian and European ethnic return migration policy offers important new perspectives on nationhood, nondiscrimination norms, and trans‐nationality. We find that despite international nondiscrimination norms, preferential ethnic return policy is common in both regions. These policies at least implicitly define the nation as existing across borders. However, there are significant regional differences. East Asian states use co‐ethnic preferences instrumentally for economic goals and also offer preferential treatment of co‐ethnic foreign investors. European states offer preferences to coethnics to protect these populations or express symbolic ties, sometimes at great expense. Thus, in Europe the state has an obligation to assist coethnics abroad, but in Asia, foreign coethnics assist the state.     

Generalizability of Gottman and Colleagues' Affective Process Models of Couples' Relationship Outcomes

The generalizability of Gottman et al's. (1998) affective process models was examined using a community-based sample of 85 married or cohabiting couples with at-risk backgrounds. Predictive associations between affective processes assessed at about age 21 years and relationship status and satisfaction approximately 2.5 years later were examined. The major findings of Gottman et al. failed to replicate. In particular, men's rejection of their partners' influence, the lack of men's deescalation of partners' negative affect, and women's negative start up were not predictive of relationship status. Further, differences in affective processes were found when comparing discussion sessions of the men's versus the women's chosen topics. The findings suggested that the validity and utility of the affective process models need further investigation.     

Investment in Shared Suppliers: Effect of Learning,Spillover, and Competition

We investigate the optimal strategies for firms to invest in their suppliers when the benefits of such investments can spillover to other firms who also source from the same suppliers. We consider two Bayesian firms that can invest in improving the quality of their shared supplier; the firms do not have complete information on the true quality of the supplier, but they update their beliefs based on the supplier's performance. We formulate the problem as an investment game and obtain Markov perfect equilibria characterized by the investment thresholds of both firms. The equilibrium investment strategies of the two firms are characterized by a region of preemption and a region of war of attrition. We also examine how the interplay between spillover, competition, and returns from the investment at shared suppliers affect the investment threshold and the time to the leader's investment, and identify the conditions under which competition delays or hastens the first investment in a shared supplier.     

Factors Associated With Substance Use Disorders Among Traumatized Homeless Youth

This study aimed to identify homeless youths’ lifestyle and trauma-related risk factors as well as protective factors associated with alcohol use disorder or no disorder and drug use disorder or no disorder. Youth receiving homeless services in Denver (n = 201), Austin (n = 200), and Los Angeles (n = 200; N = 601) completed quantitative interviews assessing demographic information, alcohol and drug use, homeless lifestyle risk factors, trauma-related risk factors, and protective factors. Findings showed differences in trauma-related risk factors between alcohol and drug use disorders, but not homeless lifestyle risks. Protective factors predicted substance use disorders beyond risk factors. Understanding trauma-related risk and protective factors associated with substance use disorders could improve interventions.     

Complex Interrelations of Trait Vulnerabilities in Mothers and their Infants

Despite the developmental and clinical relevance of this area of inquiry, no studies have examined the interrelations of trait vulnerabilities in the affective, behavioral, and interpersonal domains between mothers and their infants. Thus, this study examined the interrelations of three trait vulnerabilities (i.e., negative affective intensity, impulsivity, and insecure attachment) between mothers and their 12‐ to 23‐month‐old infants, focusing in particular on the unique and interactive influence of these maternal trait vulnerabilities on the expression of and precursors to these traits in their infants. Mother–infant dyads (N = 101) completed several laboratory procedures, and mothers reported on their own and their infants' expressions of the trait vulnerabilities of interest. Findings from this study provide preliminary evidence for intergenerational relations between these traits and suggest that it is the confluence of trait vulnerabilities in mothers that relates to the early expression of some of these traits in infants.     

刑法上的自救行为

韩国刑法典中,作为违法性阻却事由之一明确规定有"自救行为"。韩国刑法中的"自救行为"指依据法定程序不可能保全请求权时,为避免其请求权的实行不能或显著的实行困难而实施的行为,其具有在紧急状况中私人代行国家权力的行为性质。韩国刑法"自救行为"的成立需要具备如下条件:一是自救行为状况;二是自救意思;三是相当理由。一旦成立自救行为,即使发生符合构成要件的结果,也将阻却违法性而不成立犯罪。     

Intergenerational Exchanges of Middle‐Aged Adults With Their Parents and Parents‐In‐Law in Korea

The authors investigated patterns of support exchanges between Korean adult children and their parents and parents‐in‐law, gender differences in these patterns, and implications of children's marital quality for exchange patterns. Data were from a nationally representative sample of married adults (N = 920, age 30–59 years) with at least 1 living parent and 1 living parent‐in‐law. Latent class analysis was applied to 12 indicators of exchanges (financial, instrumental, emotional support given to and received from parents and parents‐in‐law). Five classes of exchanges were identified, 3 showing balanced patterns of exchanges with parents and parents‐in‐law across three types of support and 2 classes with unbalanced patterns (e.g., giving instrumental and financial but not emotional support). The findings revealed variability in intergenerational exchange patterns, with a mix of patrilineal traditional and balanced patterns. Significant associations of exchange patterns with adult children's marital quality suggest the importance of balanced exchanges with parents for marriage.     

ON THE EXTERNAL VALIDITY OF LABORATORY TAX COMPLIANCE EXPERIMENTS

An essential issue for laboratory experiments to inform policy debates is the “external validity” of the experimental results; that is, does behavior in the laboratory apply to behavior that occurs in the naturally occurring world? We examine this issue of external validity in the specific context of laboratory experiments on tax compliance, using two different types of evidence. We find that the behavioral patterns of subjects in the laboratory conform to those of individuals making a similar decision in naturally occurring settings. We also find that the behavioral responses of students are largely the same as those of nonstudents in identical experiments (JEL C9, H0, H3)
