Genomics Literacy: Implications for Teaching Students with a Range of Special Needs     

Mary Rafter  Robyn M. Gillies 《International Journal of Disability, Development & Education》2018,65(1):45-56

Recent developments in genomic-based knowledge is challenging educators to learn more about the early precursors of various difficulties children experience in learning and how they can use this information to identify preventative strategies or strategies that minimise their effect. The purpose of this article is to provide a brief outline of what is already known about some genetic disorders and some other disorders currently identified in the genome, the role of the teacher in understanding individual student needs, and how teachers can address some of the challenges posed. This article is fundamentally a review of the literature concerning genomics and genomic literacy and the implications for teachers in regular classes.  相似文献

Genomic Research and Data-Mining Technology: Implications for Personal Privacy and Informed Consent   总被引：1，自引：0，他引：1  

Tavani HT 《Ethics and Information Technology》2004,6(1):15-28

This essay examines issues involving personal privacy and informed consent that arise at the intersection of information and communication technology (ICT) and population genomics research. I begin by briefly examining the ethical, legal, and social implications (ELSI) program requirements that were established to guide researchers working on the Human Genome Project (HGP). Next I consider a case illustration involving deCODE Genetics, a privately owned genetic company in Iceland, which raises some ethical concerns that are not clearly addressed in the current ELSI guidelines. The deCODE case also illustrates some ways in which an ICT technique known as data mining has both aided and posed special challenges for researchers working in the field of population genomics. On the one hand, data-mining tools have greatly assisted researchers in mapping the human genome and in identifying certain "disease genes" common in specific populations (which, in turn, has accelerated the process of finding cures for diseases tha affect those populations). On the other hand, this technology has significantly threatened the privacy of research subjects participating in population genomics studies, who may, unwittingly, contribute to the construction of new groups (based on arbitrary and non-obvious patterns and statistical correlations) that put those subjects at risk for discrimination and stigmatization. In the final section of this paper I examine some ways in which the use of data mining in the context of population genomics research poses a critical challenge for the principle of informed consent, which traditionally has played a central role in protecting the privacy interests of research subjects participating in epidemiological studies.  相似文献

基于小波包与自适应预测器的音频隐写分析方法     

王昱洁  郭立  王翠平  丁治国 《中国科学院研究生院学报》2010,27(1):49-54

提出一种基于小波包与自适应预测器的音频隐写分析方法,主要用于检测加性噪声模型.利用加性噪声对音频高频部分比低频部分影响显著的特点,对音频信号进行小波包分解;然后利用最小均方(LMS)自适应预测器对高频小波包系数进行预测,选取预测误差的统计量作为统计特征;最后采用支持向量机分类.实验证明,对于常用的加性噪声隐写方法,即使在嵌入强度或嵌入率较低的情况下,也能达到较高的分类准确率.  相似文献   

几种苎麻园土壤微生物总DNA提取方法比较   总被引：1，自引：0，他引：1  

陈杨栋  陈婷  李力炯  曹张军  张兴群 《实验室研究与探索》2010,29(4)

实验设计对比了苎麻园土壤微生物总DNA6种提取方法。方法Ⅰ采用裂解酶、蛋白酶K、SDS与CTAB处理;方法Ⅱ结合利用CTAB、SDS、LDS和BME;方法Ⅲ综合采用玻璃珠、CTAB和SDS法;方法IV结合利用SDS-GITC-PEG;方法V利用尿素、SDS、LDS和BME综合处理;方法VI则利用试剂盒处理土壤。6种方法都可以提取到23kb左右的DNA片段,经过TENP和PVPP方法预处理的土壤样品,能有效去除腐殖酸等污染物,且提取得到的土壤总DNA完整性好、纯度高,不需要纯化就可用于PCR扩增。但不同方法取得的DNA的片段长度、产量和纯度存在明显差异。通过比较,改进并建立了可用于宏基因组构建的高纯度、大片段DNA的方法。  相似文献
