380例汉族人手指纹与血型的相关性研究 总被引：1，自引：0，他引：1
对380名正常汉族学生的指纹与血型进行了相关性研究。经X^2检验，四种血型的指纹型分布频率，各手指纹型的频率及左、右对应手指指纹组合格局均有显著差异。不同血型男女间各形指纹频率未见有性别差别。结果提示：指纹与血型之间可能有一定的相关性。 相似文献

目的：通过ABO、Rh、MNSs血型系统的遗传学调查分析,了解河北省回族的血型遗传学特征。方法：对河北北方学院2004-2008级河北省籍回族学生158人进行ABO、Rh、MNSs血型系统的基因频率及基因型频率调查、统计,并将调查结果与汉族学生进行比较分析。结果：回族学生红细胞ABO血型系统基因频率IA：0.339 2,IB：0.241 1,i：0.421 0。Rh血型系统单倍型CDE=0.082 2,CDe=0.797 5,cDE=0.107 6,cDe=0.012 7,基因频率C=0.879 7,c=0.120 3,D=1.000 0,d=0,E=0.189 9,e=0.810 1。MNSs血型系统单倍型MS=0.031 6,Ms=0.506 3,NS=0.012 7,Ns=0.449 4 基因频率M=0.537 9,N=0.442 1,S=0.044 3,s=0.955 7。结论：河北省回族红细胞ABO血型基因频率既不同于居住地的汉、满民族,也有别于其它居住区的同一民族。Rh血型系统单倍型基因频率CDe0.797 5最高 未发现Rh阴性。MNSs血型单倍型Ms〉Ns〉MS〉NS 基因频率M〉N s〉S。与国内文献报道吻合。 相似文献

研究表明,母亲ＡＢＯ血型对其子女教育过程诸因变量产生不同的影响：１．在教养态度上,母亲对子女专制态度的变量在其ＡＢＯ血型组间差异显著（ｓｉｎ．Ｆ＜．０５）;２．在子女性格上,子女任性、攻击、顺从与合作等变量在母亲ＡＢＯ血型组间差异显著（ｓｉｎ．Ｆ＜．０５）。据此,可以指导父母做好对子女的个性教育及心理医生做好对儿童的心理健康咨询工作。 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context. 相似文献
