Polymorphism and haplotype study of Y-chromosomal multi-STRs loci in Han population in Guangzhou

Using polymerase chain reaction and silver stain, polymorphism and haplotype study of Y-chromosomal multi-STRs loci: DYS19, DYS389I/II, DYS390 were studied. 111 samples of male were collected from Guangzhou area. 5 alleles were determined in DYS19 locus, 4 alleles in DYS389I locus, 5 alleles in DYS389II locus and 5 alleles in DYS390 locus. Compared with other racial populations, differences of distribution of allele frequencies existed significantly. 72 haplotype were present in this study.     

The use of the Foster & Freeman Fx5 Fibre Finder in forensic textile examinations.

The Fx5 Fibre Finder has been developed by Foster & Freeman Ltd to automatically search tape lifts for coloured fibres specified by the operator. Experiments and casework studies have been conducted to assess primarily the performance of the instrument but also, where possible, to compare it with manual searching. Tape lifts have always been manually searched at this laboratory and it is a laborious task. The use of a machine such as the Fx5 would release a scientist from many hours of low power microscopy to be free for other duties and therefore could be a valuable labour saving device in forensic textile examination.     

Parent-adolescent separation: The role of parental divorce

Previous research has identified Emotional Separation and Personal Control as two sets of home leaving indicators that are associated, respectively with relatively troubled and relatively untroubled parent-adolescent separation. As expected, among late adolescent males, parental divorce was highly related to endorsement of Emotional Separation as an important composite indicator of having left home. For females, being a firstborn was associated with endorsing Personal Control as an important composite indicator of home-leaving. Findings were interpreted as supporting previous research which has indicated that males experience more adjustment problems after parental divorce than females.Received Ph.D. from Michigan State University. Current research interests are parent-adolescent separation and perceptions of loneliness.Received Ph.D. from Michigan State University. Current research interests are adolescent-parent separation and evaluation research.     

Marine taphonomy: adipocere formation in a series of bodies recovered from a single shipwreck.

Taphonomy of marine environments has been studied mostly from individual cases. The formation of adipocere, or "grave-wax," is an important indicator of the postmortem interval. In the present paper, the conditions and the timing of adipoceric formation are observed in a series of 15 cadavers recovered at different times, over a period of 433 days, from the same contained environment. Initial foci of adipocere on the subcutaneous tissue of the cadavers were detected as early as 38 days from the time of immersion in cold (10-12 degrees C) sea water. The discrepancies between our findings and previous reports on the correlation between time since death and decomposition stages in marine environments are discussed.     

Successor Liability and Asymmetric Information

The doctrine of successor liability transfers tort liabilityarising from the seller's past conduct from the seller to thebuyer. If the buyer has as much information about the liabilityas the seller, all beneficial acquisitions take place and theseller takes the efficient level of precaution. However, ifthe seller has more information about the liability than thebuyer, not all beneficial acquisitions are consummated and theseller takes a suboptimal level of precaution. I argue that,in the presence of information asymmetry, the courts shouldincrease the damages against the (potential) seller to providebetter incentives to take precaution while decreasing the damagesagainst the buyer to encourage more beneficial asset sales.
