Identity, genealogy, and the social family: the case of donor insemination

In this paper I discuss whether or not biographical information concerning the sperm donor should be disclosed to children conceived through donor insemination. Policies of disclosure for example in the context of adoption, have been justified on the basis of a notion of identity which emphasizes genetic ties. This notion of identity and the policies of disclosure of information concerning biological parents based on it, have been criticized by many writers, including feminists, as reinforcing explanations of human organization and development based on biological determinism rather than on ideas such as social construction. Further, this notion of identity is seen to emphasize the importance of genetic parenthood over the commitment involved in bringing up a child as a social parent. While agreeing with these criticisms of that particular notion of identity, I argue that the notion of identity as a whole should not be summarily rejected. Rather, it should be re-interpreted using a sociological approach incorporating the notion of narrative. This second narrative notion of identity is developed with reference to the situation of some groups of children, who like those born from donor insemination, generally do not have any knowledge of their biological parent[s], for example adoptees, the children of the disappeared in Argentina and child migrants. In this paper, policies of disclosure which allow these children to gain some knowledge of their biological parents are discussed in light of the two notions of identity. It is argued that disclosure may be justified on the basis of a narrative notion of identity. This allows for the rigid dichotomy created between biological determinism and social construction: the importance of social parents to the child is emphasized, however the desire a child may have to know something about her or his biological parent is not denied or dismissed.     

'Stranger' child-murder: issues relating to causes and controls

Most industrialised countries are concerned with a perceived increase in the killing of children and adolescents by strangers. Though reliable statistics are lacking, the growth of serial murder suggests that more young persons may be at risk than ever before. Explanations, either of a psychological or sociological kind, of child murder by strangers are inadequately developed. Despite the tendency to see such killers as psychiatrically ill a number of studies suggest that the majority of offenders do not differ significantly, at least in psychological traits, from non-offenders. Subcultural and other sociological perspectives stressing "social disadvantage" have low levels of exploratory power and do not assist greatly in understanding child killings. Despite sketchy and contradictory evidence on the effects of the media on sexual and violent crime case study material supports the view that pornography, including popular music, may increase the propensity of individuals to commit atrocities. Counter-measures to control stranger child killing lie in more sophisticated law enforcement (profiling and computer links between police forces) long periods of incarceration of the offender and more sophisticated analyses of the crimes.     

A systematic review of drug court effects on recidivism

Drug courts have been proposed as a solution to the increasing numbers of drug involved offenders entering our criminal justice system, and they have become widespread since their introduction in 1989. Evaluations of these programs have led to mixed results. Using meta-analytic methods, we systematically reviewed the extant evidence on the effectiveness of drug courts in reducing future criminal offending. Fifty studies representing 55 evaluations were identified, including both experimental and quasi-experimental comparison group designs. The overall findings tentatively suggest that drug offenders participating in a drug court are less likely to reoffend than similar offenders sentenced to traditional correctional options. The equivocation of this conclusion stems from the generally weak methodological nature of the research in this area, although higher quality studies also observed positive results. Furthermore, the evidence tentatively suggests that drug courts using a single model (pre- or post-plea) may be more effective than those not employing these methods. These courts have a clear incentive for completion of the drug court program.

The effects of chemical and heat maceration techniques on the recovery of nuclear and mitochondrial DNA from bone

Forensic anthropologists use a number of maceration techniques to facilitate skeletal analysis of personal identity and trauma, but they may unwittingly eliminate valuable DNA evidence in the process. This study evaluated the effect of 10 maceration methods on gross bone structure and the preservation of DNA in ribs of 12 pigs (Sus scrofa). A scoring system was applied to evaluate the ease of maceration and resulting bone quality while DNA purity was quantified by optical densitometry analysis, followed by polymerase chain reaction (PCR) amplification of three mitochondrial and three nuclear loci. The results demonstrated that while mitochondrial DNA could be amplified for all experiments, cleaning treatments using bleach, hydrogen peroxide, ethylenediaminetetraacetic acid/papain, room temperature water and detergent/sodium carbonate followed by degreasing had low DNA concentrations and failed to generate nuclear PCR products. In general, treatments performed at high temperatures (90 degrees C or above) for short durations performed best. This study shows that traditionally "conservative" maceration techniques are not necessarily the best methods to yield DNA from skeletal tissue.     

High-performance liquid chromatography-ultraviolet-visible spectroscopy-electrospray ionization mass spectrometry method for acrylic and polyester forensic fiber dye analysis

A critical point of comparison between a fiber collected from a crime scene and a fiber from a known source is the color. Fiber dye analysis using thin-layer chromatography or ultraviolet (UV)-visible (Vis) microspectrophotometry provides useful, although limited, data for comparison. High-performance liquid chromatography-electrospray ionization mass spectrometry (LC/MS) overcomes these limitations by integrating chromatography, ultraviolet-visible spectroscopy, and mass spectrometry into a single instrument. In order to evaluate the applicability of the LC/MS to forensic fiber dye analysis, a multi-stage chromatographic method using acidified water and acidified acetonitrile was developed that separated and identified a mixture of 15 basic and 13 disperse dye standards. The LC/MS also detected and analyzed dyes extracted from individual 0.5 cm acrylic and polyester fibers, demonstrating its applicability to this type of analysis. With regard to the analysis of disperse dyes in polyester fibers, the replacement of pyridine with acetonitrile in the extraction system allowed direct injection of the extracts into the LC/MS. The advantage of the LC/MS over other instrumental methods of textile dye analysis is demonstrated by the analysis and differentiation of three black acrylic fibers: two fibers had similar UV-Vis spectra but were differentiated with chromatography and two had similar UV-Vis spectra and chromatograms but were differentiated using the mass spectrometer.
