This contribution draws on original data relating to a land settlement case in Araponga, an administrative area in Minas Gerais, Brazil. The settlement of the land and subsequent building of robust, more self-dependent, land-based livelihoods have followed a joint experimentation trajectory in which the agro-ecologicalisation of agrarian production practices to regenerate and enrich the resource base has been coupled with effective institutional reform and the creation of a favourable institutional setting. Key to this grassroots transformation process has been the enrolment of various strategic actors in a collaborative support network by a mediating change agent. The paper argues that the Araponga case represents a particular expression of re-peasantisation. The Araponga project has evolved without the involvement of landless peoples' social movements such as the Movimento dos Trabalhadores Rurais Sem Terra (MST). This has been crucial to its character and impact. 相似文献

There is a long-standing debate about the nature, impact and significance of processes of differentiation in driving agricultural development. This contribution discusses three ways in which such processes have been conceptualized: modernization theories that put markets centre stage, Marxist theories that focus on class, and Chayanovian approaches that highlight the dynamics within farming families. The empirical evidence for testing these concepts is normally derived from agricultural censuses. This paper uses a different database that covers all Dutch farms between 1980 and 2006 and enables us to follow the changes on individual farms. Examination of this data reveals that the actual processes of differentiation that have occurred in this 25-year period differ greatly from the classic conceptualizations. It also challenges the conventional wisdom that agricultural development is mostly driven by larger farms. 相似文献

Three decades of government budget cuts have placed significant financial pressure on Australia's cultural institutions. Institutions are increasingly trying to attract non‐government funding to fulfil their legislative mandates to collect, maintain, and exhibit Australian and international art, to educate and inform the public, and preserve Australia's political, social, and cultural history. Evidence suggests that, despite these efforts, sources of funding have not changed significantly. Budget cuts are impacting a range of areas including acquisitions, preservation, digitisation, as well as limiting access to researchers and the public. This paper concludes that a public review of the roles played by cultural institutions is required, including consideration of the level of public funding provided. To do otherwise is to ignore the importance of Australia's cultural heritage. 相似文献

Social anxiety in adolescents has frequently been linked to negative outcomes from social interactions. The present study
investigated whether socially anxious adolescents are treated negatively by their classmates and which characteristics of
socially anxious adolescents could explain negative social responses. Classroom observations of class behavior were made during
oral presentations of 94 students (60% females) in the ages of 13–18 years. Speakers’ social performance, speech quality,
and nervousness during the presentation were also rated. Findings showed that the social performance of socially anxious students
was a predictor of class behavior, whereas their overt nervousness was not. Surprisingly, the quality of their speech was
negatively related to class behavior. Implications of these findings for the treatment of socially anxious adolescents are
discussed. 相似文献

This article focuses on the core theory recently proposed by Putnam on the relationship between ethnic diversity and dimensions of social capital. Hypotheses are derived from this theory, but also from other theories that propose competing hypotheses on relationships between national characteristics and dimensions of social capital. Essentially, the authors propose more rigorous empirical tests of Putnam's hypotheses by including these competing hypotheses: tests of these hypotheses provide possibilities to evaluate Putnam's and these other theories in terms of general (i.e. cross‐national) tenability for the European continent. The general question is: To what extent do national‐level characteristics like ethnic diversity, next to other national characteristics, actually affect dimensions of social capital of individual citizens in European countries? The authors set out to answer this question by testing hypotheses on cross‐national data from 28 European countries. These data contain valid measurements of a number of dimensions of social capital. The individual‐level data are enriched with contextual‐ (i.e. national‐) level characteristics to be included in more advanced multilevel analyses. The main finding is that Putnam's hypothesis on ethnic diversity must be refuted in European societies. Instead, it is found that economic inequality and the national history of continuous democracy in European societies turn out to be more important for explaining cross‐national differences in social capital in Europe. 相似文献

This article reports on a longitudinal study investigating gender differences in the association between maternal disclosure
and adolescents’ depressive symptoms. Little research has examined the relationship of parental disclosure to adolescents’
depressive symptoms and research on sex differences is particularly lacking. In a sample of 428 families with a mean age of
13.36 (52% female) of the target adolescents, maternal and children’s disclosure and depressive symptoms were assessed twice
with an interval of 4 years. Controlling for the quality of the parent–child relationship and levels of maternal depressive
symptoms, the analyses revealed an interaction effect for child’s gender, moderating the effect of maternal disclosure on
adolescents’ depressive symptoms. Higher levels of maternal disclosure were accompanied by lower levels of depressive symptoms
in girls and higher levels of depressive symptoms in boys. Gender differences in socialization, communication, individuation
and social networks might explain why daughters and sons are differently affected by maternal disclosure. 相似文献

This study investigated genetic and environmental influences on the associations between mother–child relationship quality
(warmth and hostility) and adolescent conduct problems and cigarette use. Participants included 601 mothers and adolescent
twin pairs (aged 12–17 years). Mothers and adolescents provided separate reports of mother-to-child warmth and hostility.
A combined measure of mother and adolescent reported conduct problems was used while adolescents provided reports of their
cigarette use. Analyses were conducted using bivariate genetic analyses of correlated factors models and regression analyses
of monozygotic twin differences. Genetic influences were found for most ratings of the parent–child relationship, with evidence
of gender and/or rater-specificity for some measures. The relationship between mother–child hostility with adolescent conduct
problems and cigarette use was influenced by genetic and environmental effects. Evidence was found for shared environment
effects on the relationship between mother–child warmth and conduct problems. Examining monozygotic twin differences provided
further support for non-shared environmental influence on the relationship between mothers’ expressions of hostility and low
warmth and adolescent adjustment. Findings are discussed in relation to the interplay between genetic and environmental effects
underlying links between parent–child relations and adolescent behavior problems.

Parental Smoking-specific Communication,Adolescents’ Smoking Behavior and Friendship Selection 总被引:1,自引:0,他引:1
Rebecca N. H. de Leeuw Ron H. J. Scholte Zeena Harakeh Jan F. J. van Leeuwe Rutger C. M. E. Engels 《Journal of youth and adolescence》2008,37(10):1229-1241
In this study, we investigated whether parental smoking-specific communication is related to adolescents’ friendship-selection
processes. Furthermore, we investigated whether adolescents and their best friends influence each other over time, and what
role parents play in this process. In the present study we used data from the Family and Health project in which at baseline
428 full families participated. In this 2-year, three-wave longitudinal study data were available from fathers, mothers, early
adolescents (aged M = 13.4 years, SD = .50), and middle adolescents (aged M = 15.2 years, SD = .60). The majority of the participating adolescents were of Dutch origin (>95%). There was an almost equal distribution
of boys and girls, and adolescents with lower, middle, and higher educational levels were equally represented. Analyses were
conducted by means of Structural Equation Modeling. Results demonstrate that a high quality of the smoking-specific communication
is related to a lower likelihood of adolescent smoking, whereas the frequency is positively associated with adolescent smoking.
Both the quality and frequency of parental smoking-specific communication were related to adolescents’ selective affiliation
with (non-)smoking friends. The findings suggest that parental smoking-specific communication is associated with adolescent
smoking directly but also indirectly by influencing the friends the adolescents will associate with.
