A research note: the outcome of GC/MS/MS confirmation of hair assays on 93 cannabinoid (+) cases

This article reports the outcome of gas chromatography/tandem mass spectrometry confirmations for THC and carboxy-THC on 93 hair samples screened by RIA for cannabinoids. The samples were taken from probationers in Pinellas County, FL, who voluntarily provided the research staff with six hair and six urine specimens, collected at 1-month intervals. There were 40 samples that were RIA (+), urinalysis (−). Samples were selected which had cannabinoid (+) outcomes for hair, urine, or both. The THC and/or the carboxy-THC was (+) on confirmation. Of these 40 samples, 22 were (+) for both THC and carboxy-THC, 15 were (+) for THC but not carboxy-THC, and three were carboxy THC (+), but THC (−). Only one sample had a (+) RIA, but was (−) for both THC and carboxy-THC on confirmation. RIA detection of cannabinoids was confirmed in nearly all cases. Most cases that were RIA (−) but urine (+) were cannabinoid (+) when analyzed by GC/MS/MS.     

An empirical test of social control theory

A test of social control theory was operated on a random sample of about 2000 juveniles aged 12 to 18 years. A second test was performed 2 years later on a subsample of the original one, taking into account changes in the life situation with respect to the family, school, work, leisure, peers, and some values connected with delinquency. Both self-report data and official data were collected. Using the HOMALS technique, scales were constructed of family integration (parental control, communication with parents, family activities, and family climate), school integration (liking school, commitment to school values, school performance, and social behavior), leisure and peers (nature and involvement in leisure activities, bravado), and some normative statements. Changes in social integration were measured over a period of 2 years and compared to the impact of official intervention in delinquency cases by police or prosecutor. On the basis of path analysis and a LISREL model, we were able to conclude that there was no impact of police or prosecutor intervention on later delinquency, but there appeared to be a strong and inverse relationship between changes in social integration, or the bond with society, and the frequency of offending.This article is based on two Dutch research reports, which have been published in English inJuvenile Delinquency in the Netherlands (Junger-Tas and Block, 1988).     

13个STR基因座在亲子鉴定案例中的基因突变观察

目的 观察美国 CODIS系统的 13个 STR基因座在532例认定亲子关系的亲子鉴定案中的基因突变情况,探讨STR基因座突变率及突变类型。方法 经“Profiler Plus”及“Cofiler”试剂盒检测的587例亲子鉴定案,对其中有1～2个STR基因座不符合遗传规律者,增加HLA等血型基因和“PowerPlex16~(TM)”试剂盒检测。必要时,还增加Y-STR基因座检测和HLA等位基因测序。结果 认定亲子关系的532例,观察1052次减数分裂,发现17例亲子鉴定中的18次基因突变事件,其中16例1个STR基因座的基因发生突变,1例2个STR基因座的基因发生突变;突变的基因座包括D5S818、D3S1358、D16S539、CSFIPO、D21S11、D13S317、D7S820、vWA、D18S51和FGA,其中以FGA和D18S51基因座的突变率最高(0.29％);18次突变事件,其中来自父亲11次,来自母亲5次,无法确定2次。结论 用美国CODIS系统的STR基因座进行亲子鉴定,在有1～2个基因座不符合遗传规律时,要综合分析,并增加其它的遗传标记进行检测。     

Domestic Homicide: Neuropsychological Profiles of Murderers Who Kill Family Members and Intimate Partners

Domestic homicide is the most extreme form of domestic violence and one of the most common types of homicide. The objective was to examine differences between spontaneous domestic homicide and nondomestic homicide offenders regarding demographics, psychiatric history, crime characteristics, and neuropsychological status, utilizing neuropsychological test data from forensic examinations of 153 murderers. Using standard crime classification criteria, 33% committed spontaneous domestic homicides (SDH) and 61% committed nondomestic homicides (NDH). SDH offenders were more likely to manifest psychotic disorders, but less likely to be diagnosed with antisocial personality disorder or to have prior felony convictions. SDH offenders manifested significantly worse neuropsychological impairments than NDH offenders. The mean number of victims was lower for the SDH than the NDH group and only 14% of SDH offenders used a firearm, whereas 59% of NDH offenders used a firearm. These findings corroborate the notion that spontaneous domestic homicide may represent a discernible criminological phenotype.

General Deterrence and International Conflict: Testing Perfect Deterrence Theory

Since general deterrence necessarily precedes immediate deterrence, the analysis of general deterrence is more fundamental to an understanding of international conflict than is an analysis of immediate deterrence. Nonetheless, despite a few exceptions, the quantitative literature has ignored the subject of general deterrence, focusing almost exclusively on situations of immediate deterrence. My purpose in this essay is to fill this evidentiary gap by subjecting a recently developed theory of general deterrence—Perfect Deterrence Theory—to a systematic test by examining general deterrence from 1816–2000. The results indicate that the predictions of perfect deterrence theory are strongly supported by the empirical record.     

Sequence polymorphism in the coding region of mitochondrial genome encompassing position 8389–8865

Analysis of the polymorphic sequences in mitochondrial DNA (mtDNA) has been widely applied to forensic tests and anthropology studies. However, these polymorphic data in human have thus far been derived from the displacement-loop and intergenic regions only. Here, we report the identification of clustered polymorphic sites in the mitochondria coding region encompassing position 8389–8865. The DNA sequences of 119 unrelated Chinese were determined by PCR amplification and direct sequencing. The results showed that heteroplasmy was found in five individuals, 39 sites were noted in this 477 bp region, and 41 haplotypes were identified. The probability of identity and allelic diversity were estimated as 0.1265 and 0.8809, respectively. The results suggest that sequence polymorphism from position 8389–8865 in human mtDNA can be used as a marker for identity investigation.

Hungarian population data of eight X-linked markers in four linkage groups

The X chromosomal STR markers DXS10135 and DXS8378 in linkage group 1, DXS7132 and DXS10074 in linkage group 2, HPRTB and DXS10101 in linkage group 3, and DXS10134 and DXS7423 in linkage group 4 were studied in the Hungarian population. After genotyping unrelated men (219) and women (165), forensic efficiency parameters were calculated. Deviations from Hardy-Weinberg equilibrium could not be detected. There were several microvariant and rare alleles were sequenced: four in locus DXS10135 (alleles 17.1, 18.1, 20.1 and 26.1), one in locus DXS10074 (alleles 11), three in locus DXS10101 (alleles 26, 34.2 and 35) and five in locus DXS10134 (alleles 35.3, 37.2, 38.2, 39.2, 41).
