To our Readers

Contemporary International Relations, the English journal published by China Institutes of Contemporary International Relations, is now 15 years old. Since its conception as the first Chinese journal in English covering the field of international relations, it has presented to our readers numerous articles written by the research fellows of our institutes on the subjects of international affairs, international relations, and international relations theories. We have received numerous letters of encouragement and positive comments. We have also gotten letters in which our readers have given their opinions on what they would like to see in this journal. Some readers pointed out to us the mistakes in the translation. Other readers noted the occasional delay in delivery or even missing issues. We are grateful to those who have always supported us. We also feel the need to improve for those who have not been totally satisfied with our journal.     

Analysis of 16 Y-chromosomal STRs in an African descent sample population of Chocó (Colombia)

We studied and established a database and some parameters of forensic importance were calculated of 16 Y-STR (DYS19, DYS385, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, GATA-A10, GATA-H4 and DYS635) in a population of 298 unrelated males of African descent of Chocó (Colombia) and a total of 257 haplotypes were identified using the present set of Y-STR markers, of which 224 were represented only once in the database. Twenty-six haplotypes were presents two times, six haplotypes were presents in three individuals and one haplotype in four men. The haplotype diversity was 0.9987 ± 0.0004. By combining the allelic states of the 16 Y-chromosomal STRs we could construct highly informative haplotypes that allowed the discrimination of 86.2% of the samples tested. With this work we established a database of Y-STR and some parameters of forensic importance. This approach represents a very powerful tool for individual identification and paternity testing in forensic genetic.     

以科学发展观指导青少年犯罪防治工作

一段时期以来，我国青少年犯罪形势发生了新的变化，不仅青少年犯罪案发数有较大幅度的增长，而且青少年犯罪作案类型多样化、作案手段残忍性和作案后果严重化的特征尤为突出，有的专家学者预计，我国青少年犯罪新一轮高峰将会到来。确实，进入改革开放新时期后我国社会治安形势日趋严峻，犯罪诱发因素持续增多，例如，每年有数十万刑满释放和解除劳教的青少年将回归社会，有上百万大学生毕业后无法找到工作岗位，
