Neutral interactions among non‐native plants are common
New Phytologist, EarlyView.Global distribution of studies and overall effect of co‐invasion for all metrics of non‐native plant performance combined. Summary Globalization has accelerated the establishment of non‐native plant species, increasing the prevalence of multispecies co‐invasions; yet interactions among co‐invaders remain poorly understood.

Partisanship, Deservingness, and the Attitudinal Policy Feedback Process for Social Policy
Policy Studies Journal, EarlyView.ABSTRACT In an era of identity‐based partisan polarization, we examine whether social policies can still generate positive attitudinal feedback among beneficiaries. Drawing on nationally representative survey data, we demonstrate that partisanship conditions the policy feedback process through divergent perceptions of group deservingness.

Regional News, Regional Bias? Evidence From Media Discourses and Welfare Decisions in Germany
Policy Studies Journal, EarlyView.ABSTRACT How do media representations of immigrants shape their treatment by street‐level bureaucrats? Despite a uniform federal legal framework, decision‐making varies substantially across local welfare offices. Though prior research links national news reporting and policy implementation, little is known about how regional variation in news reporting

Zhongguo shiyan zhenduanxue, 2010 目的探讨血管紧张素原基因（AGT）T174在人群中的分布、与临床心肌梗死的相关性。方法对入选的心肌梗死患者组及健康对照组,用聚合酶链反应（PCR）、限制性片段长度多态性（RFLP）分析,对群体患者和群体健康对照组进行基因分型,统计分析。结果 AGT基因型频率及等位基因频率分布比较均匀;心肌梗死发生与民族、性别、年龄无特异相关性。174MM型和M 174等位基因的频率患者组显著高于健康对照组,携带突变型MM基因型的个体比野生型TT者患心肌梗死的危险性高5.667倍,基因突变与心肌梗死发生相关。结论 ...
