Forensic identification of urine using the DMAC test: a method validation study

Forensic scientists may sometimes be asked to identify the presence of urine in cases such as harassment, rape or murder. One popular presumptive test method uses para-dimethylaminocinnamaldehyde (DMAC), favoured because it is simple, rapid and safe. This paper confirms that DMAC reacts with urea rather than creatinine, ammonia or uric acid. Sensitivity studies found that the 0.1% w/v DMAC solution currently used for urine identification detects levels of urea found in other body fluids, potentially resulting in false positives. A 0.05% w/v solution was found to be more appropriate in terms of sensitivity to urea however the test is still not specific for urine, giving positive reactions with a number of body fluids (saliva, semen, sweat and vaginal material) and other substances (foot lotion, hair removal cream and broccoli).     

‘A jack of all trades’: the role of PIs in the establishment and management of collaborative networks in scientific knowledge commercialisation

The commercialisation of scientific knowledge has become a primary objective for universities worldwide. Collaborative research projects are viewed as the key to achieving this objective, however, the role of Principal Investigators (PIs) within these complex multi-stakeholder research projects remains under researched. This paper explores how networks in the scientific knowledge collaboration process are initiated and maintained from a multi-stakeholder perspective. It is based on case study evidence from 82 stakeholders in 17 research collaboration projects in Irish and German universities, which provides for a holistic view of the process, as opposed to prior research which has tended to report findings based on the analysis of one or two stakeholders. It finds that PIs play a lead role in establishing and managing stakeholder networks. This finding is unanimous for all stakeholders, irrespective of research centre size, type and geographical location. Not unlike the entrepreneur, the PI has to be ‘a jack of all trades’, taking on the roles of project manager, negotiator, resource acquirer as well as, the traditional academic role of Ph.D. supervision and mentoring. The findings suggest that PIs are better placed than Technology Transfer Office managers to act as boundary spanners in bridging the gap between science and industry.     

Murder in the Family: The Menendez Brothers

Childhood sexual abuse is currently a problem of considerable concern. Research suggests victims experience both short-term and long-term effects due to the unresolved trauma of sexual abuse. Erik and Lyle Menendez were convicted of first-degree murder of their parents, Jose and Kitty Menendez. During the trial the defense presented an argument of alleged sexual abuse, stating that the brothers committed the murders in fear for their lives. The aim of this paper is to explore the Menendez trial in detail from sides of the defense and prosecution, and review the pertinent literature concerning the effects of childhood sexual abuse as they apply to the case. The matter of whether or not the abuse did in fact occur remains in question. The ethical issues of sexual abuse are examined where one must decide whether Erik and Lyle Menendez are responsible for their actions if the sexual abuse did occur.     

Explaining Less Accountability: the Growth of Local Quangos

There has been substantial growth in the number of non-elected public bodies – or quangos – operating at the local level. This development presents a marked change from the model of elected local authorities as the main focus for the governance and delivery of local public services. Four interpretations of this change are examined: agency-type, ideological control, managerial restructuring and regulationist explanations. Agency-type explanations recognize a plurality of factors, but lack theoretical or predictive rigour. Ideological and managerial explanations have a stronger theoretical basis but fail to recognize the wider structural context. Regulationist explanations offer, but also suffer from the problems of, structuralist analysis. An integrating framework is developed. Three phases in the development of local quangos are presented as a process by which government has resolved tensions in the British state. A consequence, however, has been to raise questions about the state's longer term legitimacy.     

Who will make the ‘best’ use of Africa’s land? Lessons from Zimbabwe

Conflict over African land – between smallholders and large industrial farmers and between domestic farmers and global agribusinesses – raises key questions about who will make the best use of African land and which farmers do most to decrease poverty and produce more food, industrial inputs and exports. Zimbabwe has already gone through two major changes in land occupation, and thus provides an important test of what is the ‘best’ use of the land. Three measures of ‘best’ use have been cited in Zimbabwe: reward for military victory, poverty reduction and agricultural production. Initial evidence indicates that commercial smallholder production is a better use of the land than larger, more mechanised farming.
