This issue continues to explore how evaluation should respond to environmental crises; offers two contrasting answers to the question: ‘where do evaluator theories come from?’ further indicates how evaluation is adapting to non-linear, co-produced and sometimes transformational policy making; takes forward debates about the ethical and moral obligations of evaluators; demonstrates how theory-based approaches can enrich large-N evaluations; and offers a nuanced response to Ray Pawson’s critique of the use of epidemiological models to inform Covid-19 policy making.

本期继续探讨评估应如何应对环境危机；对这个问题提供了两个截然不同的答案：“评价者理论从何而来？” 进一步表明评估如何适应非线性、共同产生和有时是变革性的政策制定；推进关于评估者的伦理和道德义务的辩论；演示基于理论的方法如何丰富大型-N评估；并对 Ray Pawson 对使用流行病学模型为 Covid-19 政策制定提供信息的批评提供了细致入微的回应。
