We studied the allele frequency distribution of 21 autosomal STR loci contained in the AmpFlSTR® Identifiler™ (Applied Biosystems), the Powerplex®16 (Promega) and the FFFL (Promega) multiplex PCR kits among 936 individuals from the Royal Kingdom of Bhutan. As such these are the first published autosomal DNA results from this country. 相似文献

We consider a system made up of two committees, with overlapping membership but with different rules for passing decisions; the passage of a joint resolution requires separate approval by each committee. We show that it is possible for one voter a to be stronger (have greater voting power) than another voter b in both of the two committees, while in the two-committee system (considered as a single composite entity) b is stronger than a. We argue that this apparently paradoxical phenomenon is inherent in the structure of the decision-making system in question, rather than being an artefact of any particular index used to measure voting power. 相似文献

Abstract: The frequency and characteristics of suicide by cop cases (SBC) among a large (n = 707) nonrandom sample of North American officer-involved shootings (OIS) were investigated. “Suicide by cop” is when a subject engages in behavior which poses an apparent risk of serious injury or death, with the intent to precipitate the use of deadly force by law enforcement against the subject. Thirty-six percent of the OIS in this sample were found to be SBC with high interrater agreement (intraclass correlation coefficient = 0.93) for category classification. SBC cases were more likely to result in the death or injury of the subjects than regular OIS cases. Most SBC cases were spontaneous, but had clear verbal and behavioral indicators that occurred prior to, and during the event. Findings confirm the trend detected in earlier research that there was a growing incidence of SBC among OIS. SBC individuals had a high likelihood of possessing a weapon (80%), which was a firearm 60% of the time. Half of those with a firearm discharged it at the police during the encounter. Nineteen percent simulated weapon possession to accomplish their suicidal intent. Other findings highlight the histories and commonalities in this high risk group. 相似文献

The prevalence of serious mental illnesses in jail populations is significantly greater than in the general population. Identifying individuals who warrant psychiatric evaluations is important and benefits correctional staff as well as detainees. One widely used screening instrument intended for this task is the Referral Decision Scale (RDS). This paper reviews the development and validation of the RDS. Using data from a multisite study which assessed postrelease outcomes for detainees with mental illness, various types of validity are addressed. The results confirm that the RDS has some inherent characteristics that seriously limit its practical application as a screening instrument for use by correctional staff. 相似文献
