An innovative transfer DNA experimental design and qPCR assay to identify primary,secondary, and tertiary DNA transfer

“Touch DNA” is a form of trace DNA that is presumed to be deposited when an individual touches something and leaves behind DNA-containing skin cells, sweat, or other fluids. While touch DNA is often the result of direct contact (i.e., primary transfer), it can also be indirectly transferred between surfaces or individuals (e.g., secondary or tertiary transfer). Even experts cannot distinguish between different types of transfer and do not fully understand which variables affect direct versus indirect transfer or how often each type of transfer occurs. In this study, we utilize an innovative protocol that combines a paired male and female transfer DNA experimental design with an Amelogenin qPCR assay to generate data on primary, secondary, and tertiary DNA transfer. We report frequencies of indirect DNA transfer and also investigate the potential effects of participant age, self-identified ethnicity, and skin conditions on DNA transfer. Out of 22 experimental trials, we detected primary transfer (male + female) in 71% of trials, secondary DNA transfer in 50% of trials, and tertiary DNA transfer in 27% of trials. No significant associations were found between primary DNA transfer and age, self-identified ancestry, or skin conditions, however, all individuals with sloughing skin conditions demonstrated primary DNA transfer and we suggest this variable be explored in larger samples. These results contribute to a better understanding of the conditions under which secondary and tertiary DNA transfer occurs and can be used to propose realistic DNA transfer scenarios in court cases.

“We Can't be more Russian than the Russians”: British Policy During the Liman von Sanders Crisis, 1913–1914

This article examines British policy in the Liman von Sanders crisis, which arose between Germany and Russia in late 1913. It takes issue with recent arguments that Britain was too closely bound to the Dual Alliance of France and Russia, that concern for her Indian empire determined her foreign policy, and that the Anglo-German cooperation in 1912 and 1913 was a hollow détente. Britain played an important role in resolving the crisis, by restraining an erratic Russian policy and appealing to Germany to make concessions. Moreover, Britain was the dominant power in the entente and influenced French restraint in this crisis. This served Britain's interests in Turkey, which aimed at the strengthening of that state. Finally, the resolution of the crisis demonstrated a functioning international system, based on alliances and the Concert of Europe, not a system on the verge of collapse into war.     

Disclosing health information breaches of confidence,privacy and the notion of the "treating team"

The authors utilise cases collected during a randomised population survey to illustrate some of the legal and policy issues concerning routine transfers of information between treating practitioners. Their analysis suggests that implied consent for many routine uses of health information should not be assumed. An important part of consent to health information disclosure is the patients' ability to tailor its scope and content. This requires that they should be provided with additional information. Introducing the measures advised into the clinical setting would bring health information-gathering practices closer to compliance with the collection principles contained in Australian information privacy legislation.
