Children of immigrants who do translations and who interpret for others using their heritage language and English are known
as language brokers. Although prior research suggests that children of immigrants’ perceptions of the language brokering experience
vary greatly—from feeling a sense of efficacy to feeling a sense of burden—what remains unanswered in the literature is identification
of the antecedents and processes that help to explain the varying psychological experience of language brokers. Using data
from a two-wave prospective longitudinal study of 256 Chinese American adolescents, the present study tested potential mechanisms
that may be responsible for adolescents’ perceptions of the language brokering experience as a sense or burden or sense of
efficacy. The results demonstrate that adolescents’ Chinese orientation sets in motion a family process that is linked to
variations in the perceptions of adolescents’ language brokering experience. Adolescents who are more Chinese oriented have
a stronger sense of familial obligation, and these adolescents are more likely to perceive that they matter to their parents.
Adolescents’ perceived sense of mattering to parents, in turn, is associated positively with a sense efficacy, and negatively
with a sense of burden as language brokers. Those adolescents who are less Chinese oriented have a weaker sense of familial
obligation, and these adolescents are more likely to feel a sense of alienation from their parents. Adolescents’ sense of
perceived alienation from parents, in turn, is associated with a sense of burden as language brokers. Implications for developing
interventions for children who act as language brokers for their parents are discussed.

We examine whether the existence of civil society in Georgia has promoted social and institutional trust in the population. As much of the literature suggests, Georgia is different from its neighbors in that civil society development is more advanced. Does participation in civil society lead to more social and institutional trust? Using survey data from the Caucasus Barometer and the World Values Survey, we find that attitudes regarding social and institutional trust are more developed in Georgia than in its neighbors, and that activity in voluntary organizations is positively associated with social and institutional trust in Georgia. 相似文献

The younger siblings of childbearing adolescents have poorer school outcomes and exhibit more internalizing and externalizing problems compared to their peers without a childbearing sister. We test a model where living with an adolescent childbearing sister constitutes a major family stressor that disrupts mothers' parenting and well-being, and through which, adversely affect youths' adjustment. Data came from 243 Latino younger siblings (62% female, M age 13.7 years) and their mothers, 121 of whom lived with a childbearing adolescent sister and 122 of whom did not. Individual fixed-effects models controlled for earlier measures of each respective model construct, thereby reducing omitted variable bias from pre-existing group differences. Results show that, for boys, the relationship between living with a childbearing adolescent sister and youth outcomes was sequentially mediated through mothers' stress and parenting (i.e., monitoring and nurturance). For girls, however, the relationship was mediated through mothers' monitoring only. Findings elucidate the within-family processes that contribute to the problematic outcomes of youth living with childbearing adolescent older sisters. 相似文献

Abstract This article examines why incumbents facing non-violent demonstrations resign or remain in office. It presents a theoretical framework to analyse five major anti-government protests in Bulgaria (1990–2014) and select protests in Serbia, Romania and Macedonia. Incumbents remain in office if they perceive both the extra-institutional and electoral threats to them as low and unlikely to increase. They resign if either threat is high or increasing. To remove incumbents from power, peaceful protesters must employ an electoral strategy. This article builds on the social movement and colour revolution literatures, while underscoring the relationship between barricades and ballots. 相似文献

Participatory research approaches are increasingly popular with scientists working for poverty alleviation, sustainable rural development, and social change. This introduction offers an overview of the special issue of Development in Practice on the theme of ‘operationalising participatory research and gender analysis’. The purpose of this special issue is to add value to the discussion of methodological, practical, philosophical, political, and institutional issues involved in using gender-sensitive participatory methods. Drawing on 16 articles, we place some of the main issues, empirical experiences, and debates in participatory research and participatory technology development in the context of implementation, evaluation, and institutionalisation of participatory research and evaluation approaches. 相似文献
