技术并不会消除数字鸿沟

最近几年,像美国许多城市一样,莫德斯托(Modesto)也一直遭到媒体裁员和开支削减的冲击.记者的责任比从前更大了,他们越来越多地依靠微博、Facebook、博客、谷歌等采集新闻和报道.在这种数字转变之前,记者对美国贫穷的工人阶级的报道不仅偏少而且往往是脸谱化的或遭到扭曲的.如今,社交媒体使更多公民参与到地方新闻的制作和传播中来.这种新平台能帮助被边缘化的声音更好地在媒体上展现吗?     

世界信息与传播新秩序:浴火重生的主张

新华社社长李从军建议重新审视国际传播秩序,这使我们有机会回顾媒介历史上的那一个绚丽乐章.从上世纪70年代到90年代,从风起云涌的反帝反殖民运动,到苏东剧变,"世界信息与传播新秩序"(以下简称新秩序)概念在全球媒介政策辩论中独领风骚.这场辩论发端于发展中国家尤其是不结盟运动国家的政治论坛,继而延伸到行业与学术领域.     

美国国家档案馆:保存历史 走近国民

今天我与大家交流美国国家档案馆(NARA)在保存历史和开放档案中面临的挑战以及我们正在通过怎样的方式将美国公众与他们的档案建立起联系。一、政务公开对档案工作的影响奥巴马总统在就职第一天就发表了关于政务公开倡议的演讲,他在最近发表的

Adiponectin Gene Polymorphism and its Association with Type 2 Diabetes Mellitus

Mutations in different regions of adiponectin gene have been reported to be associated with obesity, atherosclerosis and type 2 diabetes mellitus. The present study was aimed to investigate the association among SNP 45 T > G of adiponectin gene and type 2 diabetes in South Indian population. 75 clinically diagnosed case of type 2 diabetes were studied and compared with 75 apparently healthy controls. The genotype frequency of SNP45 T > G in exon 2 of adiponectin gene was determined by PCR based restriction enzyme analysis using the restriction enzyme SmaI. (recognition site: CCC↓GGG). Three kind of genotypes: wild type TT (470 bp), heterozygous type TG (470 bp, 336 bp, 134 bp) and homozygote mutant type GG (336 bp, 134 bp) were studied. A positive association has been found between SNP45 T > G and type 2 diabetes in the study population (P = 0.010, OR = 3.797, 95% CI = 1.312–10.983). Therefore, SNP45T > G in adiponectin gene may be one of the risk factors for type 2 diabetes.     

Application of Sigma Metrics for the Assessment of Quality Assurance in Clinical Biochemistry Laboratory in India: A Pilot Study

Ensuring quality of laboratory services is the need of the hour in the field of health care. Keeping in mind the revolution ushered by six sigma concept in corporate world, health care sector may reap the benefits of the same. Six sigma provides a general methodology to describe performance on sigma scale. We aimed to gauge our laboratory performance by sigma metrics. Internal quality control (QC) data was analyzed retrospectively over a period of 6 months from July 2009 to December 2009. Laboratory mean, standard deviation and coefficient of variation were calculated for all the parameters. Sigma was calculated for both the levels of internal QC. Satisfactory sigma values (>6) were elicited for creatinine, triglycerides, SGOT, CPK-Total and Amylase. Blood urea performed poorly on the sigma scale with sigma <3. The findings of our exercise emphasize the need for detailed evaluation and adoption of ameliorative measures in order to effectuate six sigma standards for all the analytical processes.     

离开地球

“我不明白,为了一艘愚蠢的飞船,我们为什么要离开地球？”我10岁大的女儿特洛伊抱怨道。在我们把财产装上分配给我们的穿梭机的过程中,她一直都在发牢骚,破坏了所有的喜悦气氛。
