New Phytologist, EarlyView.Network of VAMP714‐dependent interactions during salt stress. Summary Plant responses to salt stress include an altered root architecture mediated by ion imbalances, reactive oxygen species (ROS) accumulation, and altered hormonal responses. Auxin is implicated in these processes.

The study of Mitochondrial DNA Gene Rearrangement in 4 species of birds(Aves: Falconiformes) [PDF]
, 2016 线粒体控制区由于进化速率快，被作为分子标记广泛应用于种群遗传学和保护生物学等领域的研究。但最近在许多鸟类的线粒体中都发现控制区存在重复拷贝，并且2个控制区拷贝之间的碱基相似度较高。因此在扩增其中一个控制区基因时可能受到另一个控制区的干扰，而对研究结果产生影响。本研究主要针对隼形目鸟类线粒体DNA(mtDNA)基因组中控制区重复及由此产生的基因重排现象进行研究，初步探讨控制区重复和基因重排产生的过程和机制。 本次实验首次对鹰科中的白头鹞(Circusaeruginosus)、日本松雀鹰 ...

Public Administration, EarlyView.ABSTRACT As the public sector increasingly adopts AI‐powered automated decision systems (ADS), understanding how citizens experience and value ADS use in public decision‐making is both normatively and practically important. Therefore, we examine and compare the effects of seven attributes of public values on citizens' support for ADS adoption in two ...

Screening and Cloning the Heavy Metal Tolerance-associated Genes in Avicennia marina (Forsk.) under Cadmium stress by Suppression Subtractive Hybridization [PDF]
, 2015 白骨壤(Avicenniamarina)作为红树林的先锋树种，广泛分布于海岸河口的低潮带，其独特的生物学和生态学特性为探索红树植物对重金属耐受性的分子机理提供了最佳的研究对象。红树林生态系统虽然承受大量重金属污染物胁迫，但对重金属污染物却表现出很强的耐受性和抗性，其中白骨壤对重金属的耐受性较其他红树植物更为突出。本研究以红树植物白骨壤为材料，研究重金属污染物镉(Cadmium)胁迫下的白骨壤幼苗基因表达差异，寻找与重金属耐受性相关的候选基因，并为红树植物的基因组研究建立相关的基因文库 ...

Do Criminalization Policies Impact Local Homelessness?
Policy Studies Journal, EarlyView.ABSTRACT Local criminalization policies draw on the logic of deterrence to levy costs on individuals who engage in behaviors that are closely associated with various public concerns, such as those criminalizing behaviors associated with homelessness, thereby potentially reducing community‐level costs.

Topics as Outcomes: Modeling the Influence of Intergovernmental Grants on Policy Diffusion
Policy Studies Journal, EarlyView.ABSTRACT Intergovernmental grants stimulate the diffusion of policy reforms, as the federal government provides states with a financial incentive to adopt policies aligned with federal priorities. Less is known about the extent to which these grants also stimulate horizontal diffusion across states.
