In this paper we analyse data from nursing handover meetings in terms of the interplay of different voices that operate at different interactional and institutional scales. We suggest, firstly, that the handover is not a single bounded event, as suggested in previous literature, but rather a gradual moving in and out of focus of a particular discourse activity; and, secondly, that while different phases within the handover as an extended event are characterised by voices operating at a specific scale, there are continuous movements between scales in each phase. This leads us to suggest two categories of rescaling as an activity: translational rescalings, as the handover shifts between phases and from one scale to another, and digressive scales, in which the scale of interaction that typifies a specific phase is temporarily interrupted by another. We illustrate how both these categories serve important revoicing functions and, on the basis of this analysis, extend the use of scales theory in interactional linguistics through the addition of dynamic systems theory and a-curve distributions, in which 20% of token types predominate, while the remainder, or tail, perform essential complementary activities that over time can open up space for gradual shifts in the characteristics and overall function of the activity itself.

护理移交为无限制和标量事件

在本文中，我们根据在不同的互动和机构规模上运作的不同声音的相互作用来分析护理移交会议的数据。我们建议，首先，移交不是像先前文献中所建议的那样是一个单一的事件，而是逐渐移入和移出特定话语活动的焦点；其次，虽然作为扩展事件的切换中的不同阶段的特征是以特定比例运行的语音，但每个阶段的比例之间都有连续的移动。这导致我们建议将重标度作为一种活动来建议：转换重标度，即移交在各个阶段之间从一个标度转移到另一个标度时，以及分散的标度，在该标度中代表特定阶段的交互作用的规模暂时被另一个中断。
