Examination of heterogeneous crossing sequences between toner and rollerball pen strokes by digital microscopy and 3-D laser profilometry

The determination of line crossing sequences between rollerball pens and laser printers presents difficulties that may not be overcome using traditional techniques. This research aimed to study the potential of digital microscopy and 3-D laser profilometry to determine line crossing sequences between a toner and an aqueous ink line. Different paper types, rollerball pens, and writing pressure were tested. Correct opinions of the sequence were given for all case scenarios, using both techniques. When the toner was printed before the ink, a light reflection was observed in all crossing specimens, while this was never observed in the other sequence types. The 3-D laser profilometry, more time-consuming, presented the main advantage of providing quantitative results. The findings confirm the potential of the 3-D laser profilometry and demonstrate the efficiency of digital microscopy as a new technique for determining the sequence of line crossings involving rollerball pen ink and toner.     

Benefits,Challenges, and Enabling Conditions of Collective Action to Promote Sustainable Production and Marketing of Products from Africa's Dry Forests

Collective action has been identified, by governments and nongovernmental organizations, as a mechanism to improve smallholder farmers' bargaining power and access to input and output markets. In many developing countries, supporting collective action has and continues to be an important policy instrument. However, in the collection and marketing of forest products, recognition of and support for producer organizations, is limited. Data, from focus group discussions, key informant interviews, and an analysis of formal producer organizations' functioning and organizational aspects, were used to examine the motives, benefits, challenges, and enabling conditions of collective action in promoting the sustainable production and marketing of shea, frankincense, and honey from dry forests in Burkina Faso, Ethiopia, and Zambia, respectively. Lessons and key recommendations, including those related to policy, are presented on how collective action through formal producer organizations could be assisted to promote responsible forest products collection and marketing practices that benefit small‐scale producers in Africa's dry forests.     

Challenging Australia's "closed" model of neonatal care: the need for reform following Re baby D (No 2)

The withdrawal or withholding of life-sustaining treatment to compromised newborns is a subject of controversy in countries where there is now highly advanced neonatal care to keep such newborns alive. The topic has generated comparatively less debate in Australia, where case law is sparse and parents and clinicians themselves make decisions regarding the cessation of care, largely free from extemal oversight. The recent case of Re Baby D (No 2) [2011] FamCA 176 endorses this "closed" approach to neonatal decision-making. This article critically discusses some of its implications and makes suggestions for reform to ensure meaningful oversight of decisions to withdraw or withhold treatment. The authors argue that the judgment fails to address some fundamental issues, such as ensuring that those with the responsibility to make decisions are doing so on a "best interests" basis. This is important because, in a society where disability remains stigmatised and poorly understood, there is no opportunity under the approach adopted in Baby D to guarantee adequate protection of the rights of individuals born with physical or intellectual impairments.     

Researching the powerful: Problems and possibilities of social research

The culture of the powerful has yet to receive the scrutiny required for social science to build up a full picture of social relations. This paper attempts to examine the problems that confront the researcher in the study of powerful groups and institutions in our society. It is based on the author's experience of working on the first piece of independent social science research commissioned by the British Ministry of Defence — an enquiry into the relations between the military and the media at times of armed conflict, with particular reference to the Falklands conflict of 1982. Powerful interests will not provide the opportunity for social scientists to study their workings at first hand. However with the increased involvement of these interests in the sponsorship of research the social scientist is in a position to relate his or her dealings with the powerful as part of the research process. The paper focusses on four aspects of the research process: the commissioning of the project, the negotiation of access to the key figures and documentary material, the research techniques used, and the response to the findings of the study.     

Environmental concerns as China modernizes

For the past fifteen years of reform, China has opened its doors to broad economic changes and to the outside world. The decentralization of both agricultural and industrial reforms has increased its pollution problems. China is now at an important crossroads in terms of balancing economic growth and environmental protection in its economic decision-making. The leaders have attempted to curb environmental degradation during the reform years through national policy, laws and regulations, and propaganda. However, there is still much work to be done, specifically in the implementation of the regulations. The reforms have sought to improve the people’s standard of living, which requires both economic growth and a healthy environmenta in which to live.     

Post-conviction DNA testing: the UK's first 'exoneration' case?

The routine incorporation of forensic DNA profiling into the criminal justice systems of the United Kingdom has been widely promoted as a device for improving the quality of investigative and prosecutorial processes. From its first uses in the 1980s, in cases of serious crime, to the now daily collection, analysis and comparison of genetic samples in the National DNA Database, DNA profiling has become a standard instrument of policing and a powerful evidential resource for prosecutors. However, the use of post-conviction DNA testing has, until recently, been uncommon in the United Kingdom. This paper explores the first case, in England, of the contribution of DNA profiling to a successful appeal against conviction by an imprisoned offender. Analysis of the details of this case is used to emphasise the ways in which novel forms of scientific evidence remain subject to traditional and heterogeneous tests of relevance and credibility.
