Gongye shui chuli采用聚合氯化铝（PAC）+聚丙烯酰胺（PAM）混凝处理焦化废水生化尾水，通过单因素实验考察了混凝剂PAC、PAM投加量对混凝处理效果的影响。基于单因素实验开展响应面混凝实验，构建PAC、PAM投加量为自变量，出水残留浊度和出水过余电导率组成的加药控制系数为响应量的数学模型并对其参数进行了响应面优化。结果表明，混凝处理最佳药剂投加量PAC为2 546.96 mg/L，PAM为10.90 mg/L，此条件下出水平均浊度残留率为4.24%、电导率过余率为2.77%、加药控制系数为7.01，与模型预测值相对误差&

Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Basic income trials and the politics of scale: A research agenda
Policy Studies Journal, Volume 54, Issue 3, August 2026.Abstract The growing popularity of basic income has led to extensive trials of the policy in numerous settings across the world. However, analysis of the politics of basic income, and in particular the political dynamics preceding and resulting from trial programs, lags. In response, we propose a research agenda that uses political scale to investigate

Narrative power in the narrative policy framework
Policy Studies Journal, Volume 54, Issue 3, August 2026.Abstract The Narrative Policy Framework lacks clear and empirical explanations of power. Yet, the study of narratives is inherently the study of power in shaping policy outputs and decisions. We develop a conceptual model positing that expressions of power (power to, with, and over) may be discovered in narrative constructs (e.g., narrative structure ...
