An African Conception of Human Rights? Comments on the Challenges of Relativism

The belief that human rights are culturally relative has been reinforced by recent attempts to develop more plausible conceptions of human rights whose philosophical foundations are closely aligned with culture-specific ideas about human nature and/or dignity. This paper contests specifically the position that a conception of human rights is culturally relative by way of contesting the claim that there is an African case in point. That is, it contests the claim that there is a unique theory of rights. It analyses three examples of what often passes as African conception of human rights arguing that they have little or nothing to do with human rights, are simply inadequate or are not African in the sense at issue in a cultural relativism. Along the way, it distinguishes between two meanings of the term African contending that to the extent that the practice of prizing the ‘community’ higher than any other value is definitive of African, the idea of African human rights remains suspect.     

The comparative endurance and efficiency of religion: a public choice perspective

The rank,stock, order and epidemic effects of technology adoption: an empirical study of bounce protection programs

Karshenas and Stoneman (RAND J Econ 24(4):503–528, 1993) gathered four theories of technology adoption: the rank, stock, order and epidemic effects. Tests of these four effects reveal support for rank and epidemic but not the stock or order effects. Since then numerous other studies have tried to find evidence in support of the stock and order effects. But evidence has been elusive, until now. Further, a survey by Frame and White (J Econ Lit 42:116–144, 2004) concludes that much more work is needed into financial innovation. This paper accomplishes three goals: (1) evidence is found to support certain technology adoption theories (the order effects and possibly the stock effects), (2) since the technology under consideration is a financial innovation called bounce protection, the paper answers Frame and White’s call for papers, and (3) refinements are made to the Karshenas and Stoneman methodology and found to be superior to the original empirical model.

Validation of the MiniFiler™ Kit in archaeological samples

We evaluate the usefulness of MiniFiler™ Kit in the field of ancient DNA. A set of samples belonging to different locations from Iberian Peninsula, with ages ranging from Neolithic to XVII century, was tested. Results could be replicated in only one burial site, probably due to the taphonomic conditions. Other cases could only produce partial or none genetic profiles.     

Hastings-Bass: the true and the spurious

In his article in Trusts and Trustees, 2007, volume 13, No 7,Dakis Hagen discussed the increasingly widespread application,and the uncertain limits, of the ‘Unruly rule in Hastings-Bass’.In this article, co-editor Tony Molloy QC questions whetherwhat has come to be called the Rule in Hastings-Bass is anythingmore than a baseless snare.     

Application of the Iscan method to two- and three-dimensional imaging of the sternal end of the right fourth rib

Age determination is a major field of interest in physical and forensic anthropology. Among the different methods based on macroscopic skeletal study, the Iscan method, which analyzes the sternal end of the right fourth rib, is one of the most reliable. We applied the Iscan method to two- and three-dimensional multislice computed tomography (MSCT) reconstructions of the sternal end of the right fourth rib on 39 ribs. The intra-observer variability on MSCT reconstructions was good (gamma coefficient equal to 0.86; value of the Krippendorff's alpha reliability equal to 0.79); inter-observer variability on MSCT reconstructions was also good (gamma coefficient ranging from 0.82 to 0.88; value of the Krippendorff's alpha reliability ranging from 0.78 to 0.86). We demonstrated excellent agreement between the results of analysis of bone samples and those of the two- and three-dimensional images, in particular regarding bone projections, morphology of the pit and of its rim. The accuracy of age estimation did not significantly differ between the Iscan method applied to dry bones and the same method applied to MSCT images. Determination of the Krippendorff's alpha reliability coefficient for the inter-error method confirmed the agreement between phase estimations obtained with the two methods (ranging from 0.55 to 0.71). The real civil age was comprised in 21 cases out of 36 for assessment performed on dry bones and in 23 cases out of 36 on MSCT reconstructions, which represented 58.3% and 63.9%, respectively. Use of MSCT reconstructions in forensic anthropology offers many advantages: no bone preparation, no damage to bone material, and the possibility of application to living individuals.     

Do drug users use less alcohol than non-drug users? A comparison of ethyl glucuronide concentrations in hair between the two groups in medico-legal cases

Two groups were selected from the remainder of hair samples that had been tested for drugs at TrichoTech for medico-legal cases: samples that tested negative (drug-negative group; N=42, age 33.4+/-7.2 years) and samples that tested positive for drugs (drug-positive group; N=57, age 32.5+/-8.8 years). A rapid, simple method to detect the ethanol metabolite, ethyl glucuronide (EtG) in hair has been developed. The hair samples were sectioned, and then submitted to overnight sonication in water. Samples then underwent SPE using anion exchange cartridges, followed by derivatisation with N,O-bis[trimethylsilyl]trifluoroacetamide (BSTFA), before confirmation by GC-MS/MS. The assay produced excellent linearity and sensitivity over the calibration range 0.02-1.0 ng/mg, assuming a 10 mg hair sample. The mean age of the two groups was not statistically different (p=0.575, Student t-test), indicating a homogeneous group. Twelve of the 57 (21.0%) hair samples of the drug-positive group tested positive for EtG, and 17 of the 42 (40.5%) hair samples of the drug-negative group tested positive for EtG. The mean concentration of EtG in the drug-positive group was 0.011 ng/mg compared to 0.107 ng/mg in the drug-negative group. When the full results of this study were subjected to statistical analysis it was shown that EtG levels in the drug-negative group were statistically higher than those found in the drug-positive group (p<0.05). This preliminary finding may be of use in the study of addiction and adds valuable data to previous studies regarding the use of EtG as a valuable marker for alcohol levels in hair.
