Stakeholder involvement in research processes is widely seen as essential to enhance the applicability of research. A common conclusion in the extensive body of literature on participatory and transdisciplinary research is the importance of the institutional context for understanding the dynamics and effectiveness of participatory projects. The role of institutional context has become increasingly important in view of large international research projects implementing shared participatory methodologies across countries (for example within Horizon 2020 and within CGIAR programmes), which each have different institutional contexts. Despite the generally accepted importance of the institutional context for understanding the unfolding of participatory and transdisciplinary research projects, surprisingly little research has actually looked into its role in greater detail. This paper aims to fill this gap in the literature by studying how a set of participatory principles and methods in a European project on integrated pest management (denoted as co-innovation in the project under study) was applied by researchers and advisers operating in a single international research project under the institutional conditions of four countries. The principal finding of this study is that, although constraints and enablers of participatory research at the personal level (e.g. researcher identity) were similar across the studied countries, research organisation- and community-based constraints and enablers differed, as well as those at the level of the overall innovation system. The institutions at different levels interact and create country-specific histories and path-dependencies, which lead to different degrees of propensity and preparedness, and hence different starting positions for participatory approaches. Consequently, when participatory research methods and approaches are applied in different contexts following a one-size-fits-all approach they may be less effective if not translated to institutional conditions at different levels. The study suggests that large international participatory research projects make provision in their design for careful selection of project team individuals, the composition of teams, and pay attention to the room for manoeuvre that the project, institute and national contexts provide for participatory research. To support the adjustment of participatory approaches to local institutional conditions, large international projects would benefit from fostering learning spaces that enable reflection on translation to local contexts and are capable of connecting to a wider network of decision makers and influencers that can facilitate institutional change in organisations and innovation systems. 相似文献

创业活动以其良好的经济与社会效益越来越受到重视,创业过程的核心是创业要素之间的动态匹配。为诠释创业理念在创业者和创业成员之间的匹配,结合创业者特质和成熟企业管理制度演化两种理论视角,提出了创业情境下管理强度的概念,并构建了其与团队合作、新创企业绩效之间的理论模型。通过107份预测试问卷和171份正式问卷进行实证分析,结果发现:创业管理强度可以被划分为独特性、统一性、共识性3个维度;创业管理强度对创业企业绩效具有显著正向影响,这种正向影响机制可以从团队合作方面得到解释,即团队合作在创业管理强度和创业企业绩效之间发挥中介作用。 相似文献

Our paper studies the impact of activity and geographic diversification on financial institution's performance. These diversification strategies are complementary in generating performance and may provide important implications. Moreover, we investigate the interaction between these two strategies. Our dataset comprises 4532 years observations over the period of 2002 to 2012 and covers 412 French financial institutions. We find a negative relationship between diversification and performance. However, this relationship is significantly positive when institutions implement a dual diversification strategy. In this paper, we propose a classification of French financial institutions. For generalists’ banks and cooperative banks, we find similar results to those of the entire sample. Furthermore, for specialized financial institutions, the relationship is positive and significant. Our findings are robust to the potential endogeneity problem and to measures of diversification and performance. 相似文献

Wheat yields from reported performance test results are of economic importance to wheat producers, since their profits depend on selecting the optimal variety for their location. However, our data shows differences in absolute and relative wheat yields between commercial and public wheat breeding program's performance test data in Kansas. Newly available data are used to test if the difference in yields arose from potential selectivity bias, and to determine the contribution of private and public wheat breeding programs to varietal yield improvement during 2007–2012. Both Heckman selection models and multiple regression showed no statistical evidence of the potential presence of selectivity bias rather, managerial practices, agronomic conditions, field location, and inherent genetic traits of the seed variety were identify as the source of yield differences. 相似文献

Tales from tails: On the empirical distributions of forecasting errors and their implication to risk
《International Journal of Forecasting》2019,35(2):687-698
When evaluating the performances of time series extrapolation methods, both researchers and practitioners typically focus on the average or median performance according to some specific error metric, such as the absolute error or the absolute percentage error. However, from a risk-assessment point of view, it is far more important to evaluate the distributions of such errors, and especially their tails. For instance, a lack of normality and symmetry in error distributions can have significant implications for decision making, such as in stock control. Moreover, frequently these distributions can only be constructed empirically, as they may be the result of a computationally-intensive non-parametric approach, such as an artificial neural network. This study proposes an approach for evaluating the empirical distributions of forecasting methods and uses it to assess eleven popular time series extrapolation approaches across two different datasets (M3 and ForeDeCk). The results highlight some very interesting tales from the tails. 相似文献

As a method of investigating complex socially relevant phenomena, transdisciplinary research (TDR) is gaining increasing centrality as a model of knowledge production. However, it is being discouraged by a scientific reward system based on disciplinary logic. The disincentive is even stronger for junior scholars who should be developing the capabilities necessary for achieving long-term scientific excellence.Building on theories of the coordination of scientific communities and using the case of a research center of Kyoto University investigating the boundary between cell and material sciences, we aim to disentangle the interplay between institutional incentives and intrinsic motivation in the prioritization of TDR over monodisciplinary research.We find that, despite strong interest in TDR among scientists and the center's mission to promote this orientation, only a minority of scientists prioritize this approach. Choice of research strategy is associated with its perceived benefits for idea generation, publication opportunities, intellectual effort required, the costs of team coordination, and satisfaction with organizational resources. Furthermore, the propensity to prioritize TDR drops among scientists beginning their careers.Therefore, we recommend the development of evaluation schemes grounded in activity-based measures and the granting of permanent positions to scientists pursuing TDR. 相似文献

Denigration of academic experts and expertise, amid a resurgence of political populism, poses a challenge to the legitimacy of academic research. Addressing this challenge requires us to continually demonstrate the importance of basing policy interventions on reliable evidence, rather than unevidenced assertions that gain traction through communication echo chambers. However, unconscious confirmation biases in collection and analysis of evidence can impair the reliability of our research insights. A key source of such confirmation biases are unchallenged ideologies and other taken-for-granted assumptions underlying any research (sub)field. This essay argues that informal and formal peer review processes at many stages of research need to highlight and challenge both conscious selectivity bias and unconscious confirmation bias. However, they are unlikely to do so where researchers only take on board feedback from peers in the same (sub)field who share ideological commitments and taken-for-granted assumptions. In such circumstances, self-referential peer review echo chambers can develop that entrench rather than challenge weaknesses in a research (sub)field. This can be a major risk to the effectiveness and reputation of any academic research (sub)field; a risk we need to confront. 相似文献
