Social Learning among Organic Farmers and the Application of the Communities of Practice Framework

ABSTRACT

The paper examines social learning processes among organic farmers and explores the application of the Community of Practice (CoP) model in this context. The analysis employed utilises an approach based on the CoP model, and considers how, or whether, this approach may be useful to understand social learning among farmers. The CoP model is applied to case studies of social learning fora among organic farmers. The case studies are compiled from in-depth semi-structured interviews and participant observation with farmers and other actors, and the data are analysed with reference to three dimensions of the CoP model, namely mutual engagement, joint enterprise and shared repertoires. Farmers associate and engage in social learning more readily with peers determined by similar attitudes to farm business, farming styles and understanding of what organic agriculture entails. Such associations support the hypothesis that CoPs are self-organising structures that generate their knowledge in sympathy with community definition and identity. A CoP framework applied within relatively unstructured and dispersed communities, such as described in this paper, emphasises the fluid nature of CoPs, and their essentially self-organising nature. Extension approaches may be facilitated by regarding farmers as de-facto members of CoPs and by understanding how CoPs may form and develop. The CoP model is applied as a heuristic to examine social learning processes in organic farming.     

Influences of Teacher–Child Social Interactions on English Language Development in a Head Start Classroom

Increasing numbers of Spanish-speaking preschool children require attention to improve the likelihood of success in school. This study, part of a larger 2-year ethnographic study of a Head Start classroom, elaborates the role of teachers’ interactions with students who were learning English. Using an interactional ethnography approach, the authors focus on the social nature of these interactions. The study illuminates the kinds of teacher interactions with students that support and hinder the students’ language learning. It reinforces the importance of student engagement in social interactions with teachers and with English other than codes of obedience and authority. Finally, it recommends actions teachers can take to provide optimal circumstances for English learning interactions for students.

浅述转轨时期中国涉外政府规制及完善

中国加入WTO过渡期结束后,国内缺乏必要的政府规制。面对国际贸易摩擦增加、外国政府保护贸易主义抬头,中国出口产品经常受到各种形式的贸易壁垒的阻击,以及屡受来自欧美等国的质疑和投诉。中国正处于经济体制转轨和加入WTO新形势双重背景下,在全球范围放松政府规制的今天,加强政府的涉外规制,对维护和保障国内经济利益尤为重要。本文首先简述政府规制的内涵与外延的界定;然后引出涉外规制的相关内容;最后尝试性地探讨在WTO规则下,中国政府在涉外规制中的具体操作和完善。     

How home gets to school: Parental control strategies predict children's school readiness

At-risk families’ control style (autonomy support and coercive control) was examined in relation to children's school readiness; children's social skills and mastery motivation were hypothesized mediating variables. In two different, low-income samples from diverse ethnic backgrounds, one preschool sample recruited from Head Start (N = 199) and a school transition sample composed of children entering elementary school (N = 344), parental control styles were related to children's academic readiness modestly but significantly in the preschool sample and weakly in the school transition sample. Children's social skills and mastery motivation skills (persistence and goal orientation) were significantly related to the academic measures of school readiness, and fully mediated the association between parents’ use of coercive behavioral control and academic readiness. Such mediation could not be tested for parental support of children's autonomy. The results indicate that a developmental cascade exists between parental control strategies and academic indices of school readiness, emphasizing the importance of family context models of school readiness. Furthermore, strong correlations between the domains of school readiness were found in both samples, reinforcing calls for a multidimensional approach to supporting school readiness in early childhood education programs.     

资本的利己本性及其超越

资本是现代社会的基础,马克思揭示了资本强势扩张的根源及其以悖论方式发展的历史趋势。为了扬弃资本的绝对利己主义异化状态,应该寻求超越资本利己本性并且引导其和谐过渡的力量。经济利他主义社会价值观,作为马克思留给我们的一份宝贵遗产,就为我们提供了这一线索。     

从CSSCI引文年代分布看中国社会科学期刊影响因子的计算

Garfield等在20世纪60年代提出的期刊影响因子是评价期刊的重要指标之一。对中文社会科学引文索引(CSSCI)来源论文之引文年代分布及其与美国社会科学引文索引(SSCI)的比较分析说明两者基本一致,对CSSCI引文中中文期刊、中文社科学术期刊及CSSCI来源期刊的年代分布分析说明:中文社科期刊的被引高峰期与国际期刊被引高峰期相同,均在其出版后的第二年和第三年。国际通用的影响因子算法完全适用于中国的中文人文社会科学期刊。     

清代滇东北矿业开发与环境变迁研究综述

滇东北矿业开发历史悠久,自汉代始就有了文献记载。其中,清代的矿业开发规模和产量最大,留下了丰富的历史资料,引起了学界关注。但学界的研究,对清代滇东北矿业开发与自然环境变迁的整体性、系统性研究很少。纵观20世纪50年代以来学界对清代滇东北矿业开发的研究,学术成果丰富,主要集中对矿业政策、生产、性质和交通运输的相关研究。本论文的研究,通过对清代澳东北地区矿业开发全貌的有机整合,侧重对矿业开发中自然环境变迁及其治理策略的研究,通过文化反思,重点揭示清代滇东北地区生态退变的原因,并从文化的角度探讨清代滇东北自然环境治理的方略。

The serendipitous impact of COVID-19 pandemic: A rare opportunity for research and practice

In this opinion paper, I argue that the Covid-19 pandemic, as tragic and disastrous as it undoubtedly is, has also given us a rare opportunity to deeply examine the research and practice of information management in particular and information systems in general. To cope with the pandemic, we have retreated to the digital world and drastically changed the way we work. Yet these very practices can well shape the way we work in the post-pandemic world. Moreover, the pandemic is also a sharp lens through which we can study deep-rooted theoretical issues that otherwise would not have surfaced, or at least remained in the background. My call to the research community is to seize this rare opportunity.
