This paper examines the various forms of rural protest directed against the United Fruit Company in Colombia between 1900 and 1964. It explores the three factors that explain the tensions between the rural population and the Company: structural tensions between the peasant economy and the export sector; the relationship between peasants and wage‐labourers; and the effects of international market cycles on local conditions. In concluding, it questions the usefulness of typologies that, by positing a structural distinction between peasants and proletarians, neglect the historical dynamics of class formation. 相似文献

The purpose of this study was to explore individual- and school-level policy characteristics on student smoking behavior using
an ecological perspective. Participants were 24,213 (51% female) Grade 10–11 students from 81 schools in five Canadian provinces.
Data were collected using student self-report surveys, written policies collected from schools, interviews with school administrators,
and school property observations to assess multiple dimensions of the school tobacco policy. The multi-level modeling results
revealed that the school a student attended was associated with his/her smoking behavior. Individual-level variables that
were associated with student smoking included lower school connectedness, a greater number of family and friends who smoked,
higher perceptions of student smoking prevalence, lower perceptions of student smoking frequency, and stronger perceptions
of the school tobacco context. School-level variables associated with student smoking included weaker policy intention indicating
prohibition and assistance to overcome tobacco addiction, weaker policy implementation involving strategies for enforcement,
and a higher number of students smoking on school property. These findings suggest that the school environment is important
to tobacco control strategies, and that various policy dimensions have unique relationships to student smoking. School tobacco
policies should be part of a comprehensive approach to adolescent tobacco use. 相似文献

The current paper aimed to investigate the effectiveness of five law enforcement interventions in disrupting and dismantling criminal networks. We tested three law enforcement interventions that targeted social capital in criminal networks (betweenness, degree and cut-set) and two interventions that targeted human capital (actors who possess money and those who possess precursor chemicals). These five interventions are compared with each other and with random (opportunistic) removal of actors in two settings: (i) with network adaptation incorporated into the simulations and (ii) without network adaptation. Results illustrate that the removal of actors based on betweenness centrality was the most efficient strategy, leading to network disruption in the least number of steps and was relatively consistent across replications. Targeting actors who possessed money was the second most effective overall and was also relatively consistent in its disruptive effect. 相似文献

Many urban, low-income adolescents experience violence, often resulting in posttraumatic stress disorder (PTSD) and depression. Narrative Exposure Therapy (NET) facilitates therapeutic processing of traumatic memories. This purpose of this study is to examine the feasibility of NET among adolescents at-risk for PTSD and depression. Two community-based agencies hosted five focus groups with adolescents (n = 28), aged 18–21, predominantly African- American (71 %) and female (61 %) and one with adolescent service providers (n = 11). Pope’s coding framework (2000) and the Socio-Ecological Model for violence prevention (Krug et al. in The Lancet, 360(9339), 1083–1088, 2002) elicited perceived barriers and facilitators to NET. Individual, relationship, and community level barriers and facilitators to NET therapy engagement were identified. The findings indicate participants have favorable attitudes about NET and the provision of the therapy within trusted community agencies. The results will inform the next steps of NET implementation, training, and psychoeducation. 相似文献
