Purpose: Changing research design and methodologies regarding how researchers articulate with end-users of technology is an important consideration in developing sustainable agricultural practices. This paper analyzes a joint experiment as a multi-stakeholder process and contributes to understand how the way of organizing social learning affects stakeholders’ ownership of process outcomes. Design/Methodology/Approach:A learning group composed of the different stakeholders of the oil palm seed system in Benin was set around a joint experiment. We use a detailed account of the group dynamics to understand the social process. Findings: The way the process is designed and conducted has a great effect on the ownership by the participants. Methodological steps taken in this research process showed its efficacy to produce quick and positive feedback mechanisms. Stakeholders’ perspectives on what constitutes a quality oil palm seedling varied widely. Participants, mainly nursery holders, learned new production practices. Representatives of the research center learned a mismatch of recommendations with users’ contexts. Field observations further to the process indicate changes in practices among stakeholders that would be sustainable. Practical Implications: Beyond focusing on outcomes, initiatives in multi-stakeholder processes should also document and analyze social processes in order to better understand the mechanisms by which such processes foster socio-technical change, as well as identify potential institutional barriers to such processes. Originality/Value: Through a detailed analysis of group dynamics, this paper addresses an important knowledge gap in participatory agricultural development. 相似文献

In 2001, the University of North Texas (UNT) Libraries developed their own electronic resource management (ERM) system to track their online resources and contracts. Over the past decade, the programming and upkeep for the homegrown system had become too much of a burden, and the decision was made to move to a vendor-supported ERM system. In the summer of 2012, UNT began the implementation of Innovative’s ERM module. This presentation covered the steps involved in that implementation and the lessons learned on how best to prepare for a radical shift in workflows and procedures. 相似文献

Scholars have recently highlighted the promise of open innovation. In this paper, we treat open innovation—in it's different forms and manifestations—as well as internal or closed innovation, as unique governance forms with different benefits and costs. We discuss how each governance form, whether open or closed, is composed of a set of instruments that access (a) different types of communication channels for knowledge sharing, (b) different types of incentives, and (c) different types of property rights for appropriating value from innovation. We focus on the innovation “problem” as the central unit of analysis, arguing for a match between problem types and governance forms, which vary from open to closed and which support alternative forms of solution search. In all, the goal of this paper is to provide a comparative framework for managing innovation, where we delineate and discuss four categories of open innovation governance forms (markets, partnerships, contests and tournaments and user or community innovation) and compare them with each other and with two internal or closed forms of innovation governance (authority and consensus-based hierarchy). 相似文献
