This paper attempts to explain why and how the middle class in Korea decisively joined the democratic movement in 1987 by drawing special attention to the role played by the middling grassroots (MG). MG was formed out of the common experience of student activism and contesting subcultures, which were widely dispersed over Korean university campuses during the 1980s. In addition, this paper examines the contrasting views on the Korean democratic transition by Bruce Cumings and Adam Przeworski. This substantive analysis attempts to show how such discord can be resolved by working out a mediating variable between action and social structure. It is suggested that the concept of MG is a good example of such a mediating variable. 相似文献

Overexpression of and RNA interference with the CCAAT enhancer-binding protein on long-term facilitation of Aplysia sensory to motor synapses 总被引:3,自引:0,他引:3 下载免费PDF全文

In the marine mollusk Aplysia, the CCAAT/enhancer-binding protein, ApC/EBP, serves as an immediate early gene in the consolidation of long-term facilitation in the synaptic connection between the sensory and motor neurons of the gill-withdrawal reflex. To further examine the role of ApC/EBP as a molecular switch of a stable form of long-term memory, we cloned the full-length coding regions of two alternatively spliced forms, the short and long form of ApC/EBP. Overexpression of each isoform by DNA microinjection resulted in a l6-fold increase in the expression of the coinjected luciferase reporter gene driven by an ERE promoter. In addition, when we overexpressed ApC/EBP in Aplysia sensory neurons, we found that the application of a single pulse of 5-HT that normally induced only short-term facilitation now induced long-term facilitation. Conversely, when we attempted to block the synthesis of native ApC/EBP by microinjecting double-strand RNA or antisense RNA, we blocked long-term facilitation in a sequence-specific manner. These data support the idea that ApC/EBP is both necessary and sufficient to consolidate short-term memory into long-term memory. Furthermore, our results suggest that this double-strand RNA interference provides a powerful tool in the study of the genes functioning in learning and memory in Aplysia by specifically inhibiting both the constitutive and induced expression of the genes. 相似文献

Emerging research shows the COVID-19 pandemic has made substantial changes to the religious climate of several nations. Surprisingly, China, the outbreak center of the pandemic, has been scarcely researched. Our study investigates how the COVID-19 pandemic has evoked new religious disaster responses and provided psychological coping mechanisms during the pandemic. We also explore how the pandemic explains surprising rates of religiosity in China. Scholars have long proposed that religious resurgence in China has been a result of individuals seeking stability in turbulent times. We bridge parallel Literatures in these areas and treat the pandemic as a natural experiment for evaluating religious behavior over time as conditioned by heightened risk perception. Utilizing a difference-in-differences estimation strategy with panel data, our study reveals that the pandemic has led to a significant increase in religiosity in China, particularly in religious areas most affected by the pandemic. We propose that even in a highly regulative religious environment, with most of its population being religiously unaffiliated, religion is a significant resource for coping in China. We take an innovative approach to demonstrate this by utilizing online search data. Our research speaks to the sociology of religion, the social psychology of risk perception, and makes application to emerging research on the unfolding COVID-19 pandemic. 相似文献

A generalized linear factor model approach to the hierarchical framework for responses and response times 下载免费PDF全文

We show how the hierarchical model for responses and response times as developed by van der Linden (2007), Fox, Klein Entink, and van der Linden (2007), Klein Entink, Fox, and van der Linden (2009), and Glas and van der Linden (2010) can be simplified to a generalized linear factor model with only the mild restriction that there is no hierarchical model at the item side. This result is valuable as it enables all well‐developed modelling tools and extensions that come with these methods. We show that the restriction we impose on the hierarchical model does not influence parameter recovery under realistic circumstances. In addition, we present two illustrative real data analyses to demonstrate the practical benefits of our approach. 相似文献

Leisure studies provide evidence that leisure engagement serves as a vehicle for improving life satisfaction among individuals with a physical disability. However, a dearth of research addresses which types of leisure activities are associated with specific psychological benefits. This study sought to capture three aspects of psychological benefits: acceptance of disability, life satisfaction, and health perception, and to explore how leisure activities are related to these psychological benefits. Using data released from the 2011 Panel Survey of Employment for the Disabled in Korea, this study found that individuals with a physical disability who participate in social activity, religious activity, and Internet use reported high health perception, life satisfaction, and disability acceptance. In particular, findings of this study provide evidence that social activity participation plays an important role in increasing health benefits among individuals with a physical disability. 相似文献

Research provides evidence that leisure-time physical activity engagement promotes health and well-being among older adults. In this study, using data released from the Health and Retirement Study (HRS) in 2008, we focused on the exploration of the relationship between leisure-time physical activity and psychological benefits such as positive affect, optimism, psychological well-being, and life satisfaction among elderly immigrants. The results of this study demonstrated that leisure-time physical activities play an important role in gaining psychological benefits. This finding provided further evidence that leisure-time physical activities provides rich opportunities for elderly immigrants to experience psychological benefits, which may contribute to quality of life and successful aging. 相似文献

According to standard practice following referral to clinical genetics, most high risk breast cancer (BC) patients in many countries receive face-to-face genetic counseling prior to BRCA-mutation testing (DNA-intake). We evaluated a novel format by prospective study: replacing the intake consultation with telephone, written and digital information sent home. Face-to-face counseling then followed BRCA-mutation testing (DNA-direct). One year after BRCA-result disclosure, 108 participants returned long-term follow-up questionnaires, of whom 59 (55 %) had previously chosen DNA-direct (intervention) versus DNA-intake (standard practice i.e., control: 45 %). Questionnaires assessed satisfaction and psychological distress. All participants were satisfied and 85 % of DNA-direct participants would choose this procedure again; 10 % would prefer DNA-intake and 5 % were undecided. In repeated measurements ANOVA, general distress (GHQ-12, p?=?0.01) and BC-specific distress (IES-bc, p?=?0.03) were lower in DNA-direct than DNA-intake at all time measurements. Heredity-specific distress (IES-her) did not differ significantly between groups. Multivariate regression analyses showed that choice of procedure did not significantly contribute to either general or heredity-specific distress. BC-specific distress (after BC diagnosis) did contribute to both general and heredity-specific distress. This suggests that higher distress scores reflected BC experience, rather than the type of genetic diagnostic procedure. In conclusion, the large majority of BC patients that used DNA-direct reported high satisfaction without increased distress both in the short term, and 1 year after conclusion of genetic testing. 相似文献

Suicide among adolescents is an emerging global public health problem as well as a socioeconomic problem. Stress-coping strategies have been shown to be associated with suicidal ideation. We examined coping behaviors related to suicidal ideation and gender differences in adolescents using the data from the 2010 Korea Youth Risk Behavior Survey (ages 12–19 years; N = 73,238). Logistic regression analysis was used to evaluate associations between suicidal ideation and specific coping behaviors while controlling for potentially confounding variables. In both male and female groups, the coping behavior “drinking alcoholic beverages” and “smoking cigarettes” were positively associated with suicidal ideation. “Watching TV,” “playing online/mobile games,” and “sleeping” were negatively associated with suicidal ideation in both groups. In males, “engaging in sports” was negatively related to suicidal ideation. In females, “venting by talking to others” and “eating” were negatively related to suicidal ideation. The results indicate that there are gender differences in the effects of coping behaviors on adolescent suicidal ideation, and that developing adaptive coping strategies may function to reduce suicidality. Future studies are needed to examine whether improving coping skills can reduce suicidal ideation in a gender-specific manner. 相似文献

Scant research has examined links between particular emotion socialization processes and child emotion functioning cross-nationally. In this study, we assessed a sample of 55 families from the United States (U.S.; 28 boys and 27 girls) and 49 families from China (27 boys and 22 girls) on family emotional expressiveness and children’s emotional experiences and regulation. Results indicated that children and families from the U.S. reported greater emotional expressiveness than their Chinese counterparts. Children from the U.S. also reported greater undercontrolled emotion than Chinese youth. Family expression of positive emotion was related to effortful emotion regulation in U.S. youth only, whereas family expression of negative emotion was associated with undercontrolled emotion for both U.S. and Chinese children. Our findings advance context-specific models of emotional development by illustrating similarities and differences in emotional functioning among U.S. and Chinese families. From a clinical perspective, the findings suggest that practitioners should consider the cultural variations of emotion communication within families when conducting both assessment and therapy. 相似文献
