Until recently, participatory and conventional approaches to agricultural research have been regarded as more or less antagonistic. This article presents evidence from three sub-projects of a Thai–Vietnamese–German collaborative research programme on ‘Sustainable Land Use and Rural Development in Mountainous Regions of Southeast Asia’, in which participatory elements were successfully integrated into conventional agricultural research as add-on activities. In all three sub-projects the costs of studying local knowledge or enhancing farmers' experimentation consisted of additional local personnel, opportunity costs of participating farmers' time, and travel costs. However, these participatory elements of the research projects constituted only a small fraction of the total costs. It may be concluded that conventional agricultural research can be complemented by participatory components in a cost-effective way, while producing meaningful benefits in terms of creating synergies by blending scientific and local knowledge, scaling up micro-level data, and highlighting farmers' constraints affecting technology adoption.  相似文献

The forensic diagnosis of cardiac contusion has hitherto been based mainly on anamnesis, concomitant thoracic injuries and the detection of macroscopic changes to the heart. Parallel histological and serological investigations of the heart-specific troponins have been conducted with varying results. This paper aims to show whether heart-specific troponins are suitable as a means of securing the diagnosis in proven cases of cardiac contusion and of determining which of the three heart-specific troponins cTnT, cTnI and cTnC are most significant in serology and histology for postmortem diagnosis.In the study, 25 cases of known cardiac contusion and 11 controls without vital myocardial trauma taken from autopsy material were prospectively investigated. Investigation of the venous serum revealed significant differences in the concentrations of the case and control groups for troponin T (mean value 5.5056 versus 0.4982; p = 0.014), for troponin C (mean value 263.9280 versus 68.5640; p = 0.001) and for troponin I (mean value 1404.0560 versus 36.1650; p = 0.003). In histology there are also significantly different depletions between the groups investigated (cTnT: p = 0.002; cTnC: p = 0.003; cTnI: p < 0.001) taking into account the autolysis time.  相似文献

Subject of the report is the question about factors of influence on the development of a common policy between the cantons in implementing the subsidizing of contributions to health insurance of persons living in modest economic circumstances. It clearly appears that this so‐called secondary harmonization in the first place has been pushed by the concretization of the executive program by the federal administration. Secondly, the influence of various forms of horizontal cooperation is mentioned, which facilitated the exchange of information and reflection between the cantons and promoted the development of a common model for a solution. Thirdly, the paper refers to the role of the evaluation, in which a comparative analysis of the sociopolitical effectiveness of the cantonal implementation systems was made. This studies induced a number of cantons to make adaptations. In spite of all tendencies towards harmonization, however, the cantonal implementation systems still differ greatly also in this public policy. This fact is explained by fundamentally differing policy cores as well as by the varying extent to which information required for the implementation of subsidizing contributions is available in the cantons.  相似文献
