关于"问题与主义"之公案的历史还原

五四时期的“问题与主义”之辩,是中国共产党思想史上的一桩“凸显之案”。本文在反思历史的基础上,对当年的“问题与主义”之辩作出实事求是的评判,挖掘其真正的思想文化内涵,恢复历史的真实面目。     

Reassessing the family-delinquency association: Do family type, family processes, and economic factors make a difference?

The present study drew on four competing theoretical perspectives to examine the relationship between family structure and juvenile delinquency. Using data from the Add Health Study, the authors examined nonserious and serious delinquent behavior across youth from different types of households and also considered how the association between family structure and delinquency might be conditioned by family processes and economic factors. Results from negative binomial regression analyses indicated that, in general, type of household was not a significant predictor of nonserious or serious delinquency. Rather, maternal attachment emerged as the most important determinant of delinquent behavior among youth from all family types. The results are discussed within the context of Hirschi's original interpretation of social control theory and future directions for research are suggested.

Wilton Marion Krogman, Ph.D. (1903-1987): the end of an era

Dr. Wilton Marion Krogman was one of the major founders of physical and forensic anthropology in the United States. His extraordinary career spanned nearly six decades, and he was universally admired and respected for his scholarship, teaching, research, wit, and humanity. While studies based on human skeletal remains have long been used to assist the medicolegal system, the late Dr. Krogman can be credited with uniting these areas into the discipline of forensic anthropology. His "Guide to the Identification of Human Skeletal Material" (1939) in the F.B.I. Law Enforcement Bulletin became the foundation of this discipline; his monumental book The Human Skeleton in Forensic Medicine (updated with the author in 1986) solidified its establishment. The purpose of this paper is to pay tribute to this great man and outline his influence on the development and advancement of forensic anthropology.     

DNA指纹的个体特异性和细胞稳定性研究

人类基因组的许多高度可变区域能够与小卫星探针杂交,而同时被检测出来,小卫星探针由串联重复的"核心"顺序构成.采用Southern印迹杂交获得的DNA指纹图包含多条高度可变的DNA片段杂交带,这些带主体细胞和生殖细胞中都表现出稳定性,而且安全具有个体特异性.本文用小卫星探针33.15,调查了北京地区的60名无关个体,     

论“四夷”称谓的变化

我国先秦时期,华夏统治者往往将公布于祖国周边地区的其他民族称为“夷、蛮、戎、狄”,有时也将其中的某一称谓与方位概念联系起来,如“东夷”、“西戎”、“北狄”之类。不过,当时不但尚未形成所谓“东夷、西戎、南蛮、北狄”的系统观念,而且就是某一称谓与具体方位的联系也不固定。如《孟子·离娄》既称舜为“东夷之人”,又称周文王姬昌为“西夷之人”,又如《诗·小雅·出车》虽将西方的民族称为“西戎”,但《书·仲虺之诰》又将其称为“西夷”,至于“蛮”在先秦文献中,从未见将其与“南”联系一起,而称“南蛮”之例。可见,当时所谓夷,蛮,戎,狄,都只不过是中原华夏统治者对周边其他民族的泛称而已。只是到了秦汉以来,为适应封建大统一需要,才将夷,蛮、戎。狄与东,南、西、北的具体方位联系起来,逐步形成所谓“东夷、西戎、南蛮、北狄”的系统观念,使这些称谓具有具体的方位性含意,而且这些称谓也逐步被赋予了歧视、侮辱性的内容。     

An in vitro study of the accuracy and precision of Breathalyzer models 900, 900A, and 1000

Ninety Breathalyzer instruments (Model 1000) and twenty instruments (Models 900, 900A) were studied using a protocol described by the Department of Transportation's "Standard for Devices to Measure Breath Alcohol." Although the mean of each of three concentrations tested (0.05, 0.10, and 0.15 g/210 L) compared favorably in both series, the standard deviation was consistently higher for the Model 1000 instruments. The Model 1000 instruments also produced a significant number of test results which exceeded the normally expected scientific deviation.     

Heroin abuse and a gas chromatographic method for determining illicit heroin samples in Singapore.

The abuse of heroin (diacetylmorphine) in Singapore escalated sharply in 1975 and 1976, as indicated by the 35-fold increase in the number of heroin seizures and the 20-fold increase in the urine samples containing morphine since 1974. A rapid and simple GC method has been described to estimate diacetylmorphine (and caffeine). Monoacetylmorphine and acetylcodeine may be ascertained by an additional step involving acetylation. All gas chromatograms of a large number of samples analyzed consistently had the same pattern, indicating that they possibly had a common origin. This GC "fingerprint," together with the quantitative data, appears to be characteristic of the illicit Asian or Chinese type of heroin found in Singapore. The proportions of the four major ingredients in some twelve typical samples have been tabulated. Statistical data confirming the accuracy and reproducibility of the analytical method have also been presented.
