Food (in)security communication: a Journal of Applied Communication Research forum addressing current challenges and future possibilities

ABSTRACT

This 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.

Investigation of Poor Academic Achievement in Children with Duchenne Muscular Dystrophy

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.     

奥运冠军米斯蒂·海曼的训练特点

美国运动员米斯蒂·海曼在悉尼奥运会女子200m蝶泳比赛中击败了该项世界纪录保持者澳大利亚苏珊 ?奥尼尔,爆出了2000年一大新闻。米斯蒂的成功,首先在于确立训练目标:增强肌肉力量,改善身体组成成份。虽然,那时她的体魄已经非常健康、匀称了,体内只有16%的脂肪,但计划要她降到12%。教练员探索她发展肌肉的突破口,为她制订了符合饮食习惯的各组食谱。训练中,主要做带有力量性、平衡性、多关节的和全身的练习,如:下蹲,静力举重,大步行进中的扩胸等练习,以增大肺活量。教练员还为她设计了提高肩后部和上背部的力量、提高腰腹部的力量和改善四头…
