ABSTRACTThis forum brings together food, (in)security, and communication. The authors participating in this forum center communication as both process and tool for understanding, mitigating, and making meaning of food (in)security. The nine authors together discuss the role of communication in food (in)security, the central challenges for scholars and practitioners working on food (in)security, and the creative possibilities and impacts influencing the future of food (in)security. The forum produces a call for applied scholars to re-imagine communication frameworks in order to make meaningful differences in their communities. 相似文献

The economic success of some of the countries within the East Asian region has generated a range of studies which have attempted to identify the sources of that growth. One strand within these analyses has focused on the critical role of schooling in the accumulation of human capital. This paper examines the role which education has played in the rapid development of the four 'Asian Tigers'; namely: Hong Kong, Taiwan, South Korea and Singapore. It is argued that whilst patterns of educational provision displayed some common features there were also significant differences in other areas such as the role of the state, sources of educational funding, the role of technical education and of the school curriculum. 相似文献

Our argument in this paper is that the model of literary progression which Bakhtin (1981, 1986) expounds in his writing on the chronotope can generate insight into the processes through which pupils improve their writing. We suggest more generally that there are concepts and clues in Bakhtin's historical model of the development of the European novel and in his theory of dialogue which can be helpful in both the evaluation and teaching of classroom writing. 相似文献

Duchenne Muscular Dystrophy (DMD) is a neurogenetic developmental disorder that presents with progressive muscular weakness. It is caused by a mutation in a gene that results in the absence of specific products that normally localize to muscle cells and the central nervous system (CNS). The majority of affected individuals have IQs within the normal range, generally with lower verbal than performance IQ scores. Prior work has demonstrated selective deficits on tests of verbal span and immediate memory. For the current study, 26 boys with DMD (and normal intellectual function) and their unaffected siblings were evaluated. Paired comparisons demonstrated that the children with DMD had significantly poorer academic achievement scores than their siblings, even though their vocabulary levels and home and educational environments were comparable. Children with DMD also had more behavioral concerns, physical disabilities, and poorer verbal memory spans. Linear regression indicated that behavioral concerns, executive function, and physical disability did not contribute substantially to academic performance, whereas performance on verbal span did. DMD presents with a selective developmental aberration in verbal span that has wide‐ranging consequences on learning skills. 相似文献
