DNA Commission of the International Society of Forensic Genetics (ISFG): an update of the recommendations on the use of Y-STRs in forensic analysis

The DNA Commission of the International Society of Forensic Genetics (ISFG) regularly publishes guidelines and recommendations concerning the application of DNA polymorphisms to the problems of human identification. A previous recommendation published in 2001 has already addressed Y-chromosome polymorphisms, with particular emphasis on short tandem repeats (STRs). Since then, the use of Y-STRs has become very popular, and a numerous new loci have been introduced. The current recommendations address important aspects to clarify problems regarding the nomenclature, the definition of loci and alleles, population genetics and reporting methods.     

Data for Y-chromosome haplotypes defined by 17 STRs (AmpFLSTR Yfiler) in two Tunisian Berber communities

The 17 Y-chromosomal short tandem repeats (STRs) included in the AmpFLSTR Yfiler PCR Amplification Kit (AB Applied Biosystems) (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and GATA H4) were typed in two Berber communities, a small village (Takrouna) and a town (Sejenane), from North Tunisia. As expected, diversity was higher in the town, even when compared with a pool of three small Berber communities, probably due to the combination of different founder effects and genetic drifts operating in the small villages.     

Who Should Govern Political Parties? Organizational Values in Norwegian and Danish Political Parties

The article explores party member attitudes towards internal party democracy and party leadership in Danish and Norwegian parties. The focus is on the relationship between party members' public policy values (measured by means of 'old politics' and 'new politics' value dimensions) and their organizational values (i.e. ideas about internal democracy), but the members' educational and activism levels as well as indicators capturing factors specific to individual parties are also applied to explain party members' organizational values. We find that positions on the two policy value dimensions are related to party members' organizational values. But the relationships are not particularly strong, and their signs are contrary to expectations. One explanation may be that the 'new politics' literature draws a misleading picture of the organizational values of New Left and New Right party members – at least in the Danish and Norwegian cases. We also find that the social democratic parties in both countries differ considerably from the other parties in the sense that the dissatisfaction with the leadership was much stronger in these parties.     

Getting the Order Right: Child Support Guidelines and the Cost of Raising Children

This article argues that the United States Department of Agriculture’s (USDA) estimates of parental expenditures on children are an appropriate economic foundation for state child support guidelines. The USDA’s estimates are consistent with the public policy purposes of state guidelines and may improve the extent to which they accomplish federal intent. The article examines the role of valid and reliable child cost estimates in advancing the policy objectives for child support, summarizes the theoretical and empirical challenges of estimating those costs, suggests the limitations of the most widely used estimation methods in relation to the policy purposes described earlier, and evaluates the USDA’s method in relation to those same purposes. The evidence suggests that guidelines based on the USDA’s estimates are more likely than the most commonly used estimates to yield adequate child support orders and to allocate economic responsibility for children appropriately among the custodial parent, the noncustodial parent, and the state.     

Results of the GEP-ISFG collaborative study on two Y-STRs tetraplexes: GEPY I (DYS461, GATA C4, DYS437 and DYS438) and GEPY II (DYS460, GATA A10, GATA H4 and DYS439)

A collaborative exercise was carried out by the Spanish and Portuguese ISFG Working Group (GEP-ISFG) in order to evaluate the performance of two Y-chromosome STR PCR tetraplexes, which include the loci DYS461, GATA C4, DYS437 and DYS438 (GEPY I), and DYS460, GATA A10, GATA H4 and DYS439 (GEPY II). The participating laboratories were asked to type three samples for the eight markers, using a specific amplification protocol. In addition, two control samples, with known haplotypes, were provided. The results obtained by the 13 different participating laboratories were identical, except for two laboratories that failed to type correctly the same two samples for GATA C4. By sequence analyses, two different GATA C4 allele structures were found. One control sample (allele 21) and two questioned samples (allele 22, correctly typed by all the laboratories, and allele 25) presented the following repeat structure: (TCTA)4(TGTA)2(TCTA)2(TGTA)2(TCTA)n, but different from the one found for allele 26 in one sample included in this exercise, as well as in the second control sample (allele 23), namely (TCTA)4(TGTA)2(TCTA)2(TGTA)2(TCTA)2(TGTA)2(TCTA)n. The collaborative exercise results proved that both Y-tetraplexes produce good amplification results, with the advantage of being efficiently typed using different separation and detection methodologies. However, since GATA C4 repeat presents a complex structure, with alleles differing in sequence structure, efficient denaturing conditions should be followed in order to avoid typing errors due to sizing problems.     

Alcohol use among fatally injured drivers in Spain

Blood from 285 fatally injured drivers in Northern Spain was collected and tested for the presence of alcohol and drugs. Alcohol was detected in 50.5% of all fatalities. Alcohol alone was detected in 44.2% of all samples and in the remaining 6.3% another substance was found together with alcohol. Blood alcohol concentration was classified in different levels. It has been observed that in 35.4% of the cases the blood alcohol level was > or = 0.8 g/l, the legal limit in Spain for car drivers. Alcohol together with other substances was encountered in 18 cases, with medication in 22.2% (4 out of 18), alcohol with illegal drugs in 66.6% of the cases (12 out of 18), and alcohol with medicines and illegal drugs in 11.1% (2 out of 18). Cocaine was the most commonly detected drug. The study shows how widespread the incidence of a high level of alcohol concentration among drivers involved in fatal accidents in Spain.

Fathers' rights, women's losses

Recent international moves to defend the family, protect and enhance the rights of men. For example, state proposals to redefine illegitimacy extend men's rights in marriage to unmarried men. Women are losing the choice to bring up children on our own, or together, without men.The position of men in the family is not based upon equality with women. Fatherhood is not the equivalent of motherhood, nor the support for it. The particular right of fatherhood is the right of men to take up a social position of authority over women and children. This is not an interchangeable position, for fatherhood is accrued solely to men. Social policies which encourage the presence of men in all families, and support the ‘role’ of father, perpetuate sexual inequality and discrimination against women.
