公安大学生性格类型刍议

研究公安大学生的性格类型,培养他们胜任公安工作需求的性格特征是公安教育培训日益面临的重大挑战。本文采用人格测量工具MBTI-M版,对上海公安高等专科学校123名公安大学生的性格类型进行了研究,结果表明,公安大学生的性格类型分布不均衡,ESFJ(外向-感觉-情感-判断)和ESTJ(外向-感觉-思考-判断)是公安大学生典型的性格类型。但是,还有不少学生具有内向、直觉、情感与感知的性格偏好,为了有助于他们更好地适应将来从事的公安工作,学校对他们开展有针对性的心理健康教育,扬长避短,帮助他们完善发展自我。     

Homogeneity tests among groups for microsatellite data

We propose a homogeneity test among groups on a quadratic distance measure. The underlying mutation process in the microsatellite loci is studied using the stepwise mutation model. Asymptotic normality of the test statistic is proved under very mild regularity conditions. Resampling methods, such as jackknife, are used in the application to build confidence intervals for the difference in allelic variation between and within groups. The method is applied in a real data to test whether there are differences in the distribution of the repeated sequence among groups defined by ethnicity and alcoholism index (ALDX1).
