Participatory technology development in agricultural mechanisation in Nepal: how it happened and lessons learned

International Wheat and Maize Improvement Center (CIMMYT) projects on new resource-conservation technologies (RCTs) in the Indo-Gangetic Plains of Nepal aimed to strengthen equity of access, poverty reduction, and gender orientation in current rural mechanisation processes – more specifically, to promote machine-based resource conservation and drudgery-reduction technologies among smallholder farmers. These projects, together with other projects and other actors, gave rise to an informal ‘coalition’ project, which used participatory technology development (PTD) approaches, where farmers, engineers, scientists, and other partners worked towards equitable access to new RCTs. This experience showed that PTD projects need to be flexible, making use of learning and change approaches. Once successful adoption is occurring, then what? Such projects need to ensure that everyone is benefiting in terms of social inclusion and equity; this might necessitate new unforeseen work.     

The effect of chlorine and hydrogen chloride on latent fingermark evidence

Exposure of forensic evidence to either hydrogen chloride or chlorine can result in acidification to such an extent that enhancement of fingermarks with ninhydrin or cyanoacrylate is inhibited. Under these circumstances, pretreatment of samples with volatile bases such as triethylamine or ethanolamine prior to using these enhancement techniques can lead to successful visualization of fingermarks. Alternatively, physical enhancement techniques such as powder dusting or small particle reagent can be used on acidified non-porous substrates, although the former technique is subject to increased background under such conditions.     

The tools to understand: community as co-researcher on culture-specific protective factors for Alaska Natives

A collaborative research process engaging Alaska Native communities in the study of protective factors in Alaska Native sobriety and the design of a preventative intervention using its findings is described. Study 1 was discovery oriented qualitative research whose objectives were identification of protective factors and development of a heuristic model. Study 2 involved quantitative survey methods to develop and test ameasure of protective factors identified by the qualitative study. Empirical data from these studies is presented, and the role of Alaska Native co-researchers who did not possess specialist research training is described in the design and implementation of the study, interpretation of findings, and design of the intervention model and tools. Benefits that emerged from co-researcher involvement in this process, to the community and to the co-researchers themselves, are described.
