This article examines the boundary work of frames and the methodological significance of understanding this work when conducting rhetorical framing analysis. While the boundary properties of frames have been theorized by scholars, there remains a lack of clear engagement with how to effectively address these discursive boundaries methodically. I argue that agenda-dismissal, which makes use of both prolepses and blind spots, ought to be addressed in addition to agenda-setting and agenda-extension when conducting rhetorical framing analysis. A case study is provided in which the rhetorical framing of vegan parenting in online news media is analyzed and critiqued for confining the issue within a dominant health-based frame. Strategies for dismantling discursive boundaries and reframing public issues are also considered within the context of the case study.

本文考察了框架的边界工作以及在进行修辞框架分析时理解这项工作的方法论意义。虽然学者们已经对框架的边界属性进行了理论化，但对于如何有条不紊地有效解决这些话语边界仍然缺乏明确的参与。我认为，在进行修辞框架分析时，除了议程设置和议程扩展之外，还应该解决同时利用 proleps 和盲点的议程取消。提供了一个案例研究，其中分析和批评在线新闻媒体中纯素养育的修辞框架，以将问题限制在以健康为基础的主导框架内。
