To demonstrate how fuzzy cognitive maps may be used to extract, present and compare Aboriginal perspectives, using the determinants of diabetes as a case study.
Participants from the Mohawk Community of Akwesasne and the Miawpukek First Nation in Conne River created fuzzy cognitive maps (FCMs) (N=3) detailing their views of "the causes of diabetes in their community", through a facilitated, group mapping session. For each FCM, the net causal effect of every determinant (direct or indirect) on diabetes was calculated from its transitive closure. The net causal effects were then compared across the set of FCMs to identify strong, weak and controversial determinants.
Comparison of FCMs revealed significant heterogeneity in the perspectives of diabetes. The Akwesasne participants focused heavily on social, traditional and spiritual factors, while Conne River participants placed more importance on direct personal and lifestyle factors. There was, however, a core of strong, validated determinants related primarily to healthy diet and physical activity.
This work demonstrates how FCM may be used to extract and represent different perspectives of complex issues allowing for comparisons among stakeholders or knowledge groups. Comparison of multiple FCM employing the transitive closure may then be used to identify areas of agreement and controversy.
以糖尿病的决定因素为案例研究，展示如何使用模糊认知图来提取、呈现和比较原住民的观点。
来自阿克瓦斯奈莫霍克社区和康内河米奥普克克第一民族的参与者通过一次有引导的小组绘图会议，创建了详细描述他们对“社区中糖尿病病因”看法的模糊认知图（FCM）（N = 3）。对于每个FCM，从其传递闭包计算每个决定因素（直接或间接）对糖尿病的净因果效应。然后在一组FCM之间比较净因果效应，以识别强、弱和有争议的决定因素。
FCM的比较揭示了糖尿病观点的显著异质性。阿克瓦斯奈的参与者主要关注社会、传统和精神因素，而康内河的参与者更重视直接的个人和生活方式因素。然而，存在一个主要与健康饮食和体育活动相关的经过验证的强决定因素核心。
这项工作展示了FCM如何用于提取和呈现复杂问题的不同观点，从而允许利益相关者或知识群体之间进行比较。然后，使用传递闭包对多个FCM进行比较，可用于识别一致和有争议的领域。
