Across the globe, the countryside faces the “generation problem”: Who will grow food when the current generation of aging small farmers and peasants disappears? A combination of objective and subjective factors effectively discourages young people from assuming the continuity of peasant and family farming, especially in countries that have experienced significant neoliberal dismantling of rural infrastructure and education. Rural social movements are increasingly building educational processes linked with small-scale, ecological farming in the hopes of reinforcing the development of identities and skills for peasant futures and cadre in the struggle for popular land reform, agroecology, and food sovereignty.  相似文献

ABSTRACT

Little is known about rates and correlates of service use or the role that social context plays in service engagement among homeless youth. This study compares two distinct service areas and uses a social network approach to examine how environmental factors (e.g., neighborhood), social factors (e.g., social capital and network engagement) and individual level factors that relate to service use patterns among homeless youth in Los Angeles, California. A sample of 938 youth was recruited from three drop-in centers in two distinct service sites. Individuals were surveyed about their individual and social network attributes. Univariable and multivariable analyses were utilized to understand the influence of social-contextual variables on service use. Service use behaviors varied across site and service type with youth in Hollywood showing greater engagement than youth at the Beach site. Across both sites and several service types, staff emotional support was positively correlated with levels of service use. The site comparisons also point to the fact that even within a single geographic area, like Los Angeles County, client profiles and rates of service use can significantly vary. Future research needs are presented with specific emphasis on understanding the needs of non-service-seeking youth.  相似文献

The generalized jackknife is used to reduce the bias of an estimator, based on frequency moments, of the Pareto shape parameter. Computations of amount of bias reduction and simulations of mean-squared errors are presented.  相似文献

In this paper modified Edgeworth and Cornish-Fisher expansions are introduced. These expansions do not require knowing the cumulants of the distributions involved. More importantly, the new expansions have no singularities.  相似文献

In 2004, as part of its initiative to widen access, a Scottish university offered places for the first time to a group of students coming from further education (FE) colleges with Higher National Certificates (HNCs) and Higher National Diplomas (HNDs). A longitudinal study has followed the experiences of transition and subsequent progression of this cohort of students. The study, entitled ‘From FE to HE’ has interviewed and surveyed 45 students at key points since 2004. This paper reports on findings from the study overall, giving particular attention to the views and experiences of the nine Social Work students within the cohort. It will be argued that whilst FE colleges provide considerable support for their students, there is no easy transition to an ancient, research‐led university such as this one. The findings of this study have implications for all those involved in social work education.  相似文献

Despite the large body of scholarship on drag and its performance of misogyny, mimicry, and masculinity, little attention has been paid to the role of musical genres in Black drag performance and its reception. This essay explores drag performances of gospel music and its relationship with the spectator at the Biology Bar, a Black gay drag site in Chicago. By examining the shift from the club "space" to the church "place," this research locates several possibilities for queer gospel performances. Through the introduction of a theory of transformance, this essay highlights the contradictions, complications, and complexities of the relationship between the Black church and the Black gay community.  相似文献

This study investigated the effects of age, hearing loss, and cochlear implantation on mothers' speech to infants and children. We recorded normal‐hearing (NH) mothers speaking to their children as they typically would do at home and speaking to an adult experimenter. Nine infants (10–37 months) were hearing‐impaired and had used a cochlear implant (CI) for 3 to 18 months. Eighteen NH infants and children were matched either by chronological age (10–37 months) or hearing experience (3–18 months) to the CI children. Prosodic characteristics such as fundamental frequency, utterance duration, and pause duration were measured across utterances in the speech samples. The results revealed that mothers use a typical infant‐directed speech style when speaking to hearing‐impaired children with CIs. The results also suggested that NH mothers speak with more similar vocal styles to NH children and hearing‐impaired children with CIs when matched by hearing experience rather than chronological age. Thus, mothers are sensitive to hearing experience and linguistic abilities of their NH children as well as hearing‐impaired children with CIs.  相似文献
