This article discusses the trial of visual research methods in a socio-economic research and development project with women subsistence farmers and their families in two regions of Papua New Guinea (PNG). It reports on the benefits and challenges of three visual research methods (drawing, participatory photography, and picture elicitation) to explore the agricultural practice of women subsistence farmers and their families. The paper discusses the potential of these methods for enhancing community engagement, reducing the power imbalance between researchers and participants, and promoting dialogue and reflection to better understand the needs and practices of subsistence farmers. 相似文献

Violations of human rights in the context of a conflict have in recent years received an increasing amount of attention from the international media. Yet how such media attention influences conflict remains understudied and, a priori, uncertain. On the one hand, media coverage of human rights abuses may constitute “naming and shaming” that might temper hostilities. On the other hand, such coverage might spark intransigence and complicate negotiations among conflicting parties, thereby hindering rather than hastening peace. This article tries to adjudicate among these and other possibilities by exploring how media reporting on human rights abuses influences the development of conflicts. The analysis reveals that such reporting is associated with shorter conflicts and negotiated agreements between fighting parties. 相似文献

This article presents experiences with collaborative and on-farm research based on the implementation of a four-year Programme for Agricultural and Natural Resources Transformation for Improved Livelihoods (PANTIL) at Sokoine University of Agriculture (SUA) in Morogoro, Tanzania. It outlines the basic elements in the implementation of a programme aimed to be demand-based, and discusses the challenges encountered in combining collaborative research with the empowerment of farmers. Finally, the article draws out some lessons with implications for the future organisation of collaborative and on-farm agricultural research. 相似文献

Local knowledge has continued to gain popularity among development practitioners in the last four decades. However, the future of local knowledge seems hazy to some academics and researchers, perhaps due to the methodological challenges in operationalising local knowledge in development research. Rather than appropriate its full potential for sustainable (global) progress, renditions on the relevance of local knowledge in development research agenda have largely become rhetoric. Nonetheless, this viewpoint outlines 20 pertinent reasons in support of the relevance of local knowledge and why it has a future in development theory and practice. 相似文献

In many criminal and civil cases, some questioned documents are written with iron gall ink. Determining the date when an iron gall ink entry was written can be important to assess the authenticity of a document. A dissolution‐diffusion method was successfully employed to draw aging curves of iron gall ink entries stored in controlled conditions over 40 months. Calibration curves were created to indicate the relationship between the average dissolution‐diffusion rate of ink components and the age of ink entries stored under natural aging conditions. As preliminary findings of this study, the mixed solution of dimethyl formamide (DMF) and anhydrous ethanol was suitable to dissolve the dye of iron gall ink strokes made at different time. It was also determined that brands of iron gall inks, types of paper, and thickness of iron gall ink strokes had varying impacts on estimating the dates of iron gall ink strokes. 相似文献

Modeling Bone Surface Morphology: A Fully Quantitative Method for Age‐at‐Death Estimation Using the Pubic Symphysis

The pubic symphysis is widely used in age estimation for the adult skeleton. Standard practice requires the visual comparison of surface morphology against criteria representing predefined phases and the estimation of case‐specific age from an age range associated with the chosen phase. Known problems of method and observer error necessitate alternative tools to quantify age‐related change in pubic morphology. This paper presents an objective, fully quantitative method for estimating age‐at‐death from the skeleton, which exploits a variance‐based score of surface complexity computed from vertices obtained from a scanner sampling the pubic symphysis. For laser scans from 41 modern American male skeletons, this method produces results that are significantly associated with known age‐at‐death (RMSE = 17.15 years). Chronological age is predicted, therefore, equally well, if not, better, with this robust, objective, and fully quantitative method than with prevailing phase‐aging systems. This method contributes to forensic casework by responding to medico‐legal expectations for evidence standards. 相似文献

Matching pairs of skeletal elements is of fundamental importance when re‐associating skeletons from commingled settings. This study presents a new method that combines the use of traditional anthropometric size measurements and the analysis of shape, through geometric morphometrics, to form pairs from commingled settings. We tested the hypothesis that shape asymmetry among individuals is smaller than between individuals that share similar dimensions. The metacarpals were measured in their maximum length, and absolute means of asymmetry between right and left metacarpals were calculated. To analyze the shape characteristics, two‐dimensional landmarks were recorded from digital images of 111 metacarpals. The specimens were analyzed using generalized Procrustes analysis and multivariate statistics. The accuracy of pair‐matching bones using a combined method was of 100%, showing that the incorporation of geometric morphometrics techniques—in the assessment of shape in physical anthropology—is of particular use when comparing the shape differences/similarities between individuals. 相似文献

Identification of human remains is often achieved by comparing documented reference data with the same type of evidence obtained from the remains. We present a case of a decomposed unidentified body, whose identity was presumed but because of the low validity range of the available data, the identification process could not be completed. Antemortem radiographs of the teeth found in the house of the reputed victim could not be compared to the edentulous cadaver and the kinship between the victim and the only living relative that could provide DNA for comparison was too tenuous. Isolated teeth found at the scene, were neither a source of DNA reference information nor questioned data to be compared to the antemortem radiographs. The strategy implemented by the investigators to reallocate the status of the isolated teeth from the questioned source to the reference source of DNA to be compared with the cadaver is presented. 相似文献

European Human Rights Law and the Normalisation of the ‘Closed Material Procedure’: Limit or Source?

Once a legal abnormality that was criticised on human rights grounds, the closed material procedure (CMP) has now become the main mechanism for dealing with allegedly sensitive security information in the UK. This article considers the role of European human rights law in that process. It argues that the CMP can be conceptualised as the product of human rights law, which has developed so as to legalise and normalise its use, and that this process is symptomatic of a deeper inter‐relationship between human rights law and the preservation of states' security interests, which renders the former inherently unsuitable for dealing with security phenomena. 相似文献
