ABSTRACT In public archives there are a number of hand-embroidered cloths worked by suffragettes incarcerated in Holloway Prison between 1911 and 1912. Denied political status, some of the embroiderers used the hunger strike as a political tool and were forcibly fed. In this paper the embroideries are reframed as material and discursive evidence of suffragette prison experiences. The material narratives of the embroidered cloths are traced, drawing on a dialogue between critical theory, material object enquiry, practice as research and the work of contemporary textile practitioners. Embroidering by suffragettes is explored as an embodied and situated ‘thread act’ that materialised the making of networks, the need for protection of the body and mind, the powers and dangers of boundary crossing, and proto-political thinking. 相似文献

Restriction fragment length polymorphism (RFLP) analysis for the purpose of individualization is now being used in casework in the People's Republic of China. This report describes the use of the multilocus minisatellite probe 33.15 to solve three cases, including two homicides and a rape. In the third case, fetal tissue was analyzed to prove that the alleged rapist was, in fact, the father. In each case, analysis of deoxyribonucleic acid (DNA) resulted in a positive match. The probability of chance association of the DNA fingerprint was calculated as 5.6 x 10(-12), which is similar to the figures reported in the literature. 相似文献

The individuality of fibres used to provide forensic evidence--not all blue polyesters are the same.
Fibres used in forensic casework suffer from a disadvantage common to other forms of trace evidence--it is not possible to state with absolute certainty that they originate from a specific source. Target fibre studies, population studies and research on 'blocks of colour' have effectively demonstrated the polymorphism of textile fibres (particularly man-made ones) and have shown that when a fibre is believed to have a specific putative source, the chance that it has originated from a different source purely by coincidence is extremely remote. A study by Houck MM (Houck MM, Inter-comparison of unrelated fibre evidence. Forensic Science International 2003; 135: 146-149) has shown that no coincidental matching fibres were recovered from items of clothing examined in 20 unrelated crimes. The study involved over two million comparisons. This work goes a step further, and using the example of blue polyester fibres shows that even within a very narrow segment of the whole general fibre population, many examples of a specific colour/type of man-made fibre taken from random sources can be compared and the chance of any two being the same is very low. These studies should help to show the specificity and value of transferred fibres in providing forensic evidence. 相似文献

Legal context: The relatively informal agreements setting up the TrilateralCooperation (TC) among the world's three most important patentoffices are contrasted with formal multinational treaties suchas the Patent Law Treaty and the abortive Substantive PatentLaw Treaty. Key points: After its inception in 1983, the TC concentrated initially ondeveloping and implementing standards for electronic storageand retrieval of prior art documents, and facilitation of searching.This was later extended to electronic sharing of priority documentsand to standardization and searching of DNA sequence databases.More recently emphasis has been placed on harmonization of searchingand examination procedures, and working groups have comparedthe approaches of the Trilateral Offices (TOs) to the patentabilityof claims in areas of new technology. Encouragingly, the resultsare usually the same, although the specific objections raisedmay differ. The ultimate goal is to reach a situation in whicha claim allowed by one TO would be accepted by the others withoutfurther examination. Practical significance: The TC has already facilitated search and examination, leadingto lower costs and shorter pendency times than would otherwisebe the case. Further progress depends on harmonization of substantivepatent law, which in turn depends on the willingness of theUSA to accept a first-to-file system. 相似文献

After the Agreement on the Trade-Related Aspects of Intellectual Property Rights (TRIPS) came into operation in 1995 developing countries have found themselves in a process of continual negotiation over intellectual property rights and access to medicines. These negotiations have taken place in the World Trade Organization and in the context of free trade agreements. The paper suggests that the only real win for developing countries has been the Doha Declaration on the TRIPS Agreement and Public Health in 2001. What have been the lessons for developing countries in a decade of negotiations over access to medicines? Drawing on themes of rule complexity and regulatory ritualism the paper discusses four key lessons for developing countries. It concludes by arguing that developing countries will do better if they adopt a networked governance approach to negotiation rather than continuing to rely on traditional coalition formation. 相似文献
