ABSTRACT Two‐dimensional MXene‐based materials have recently attracted attention in supercapacitors and lithium ion batteries due to their excellent electrochemical performance. However, the capacity and agglomerate limits the development of MXene‐based materials.

The Next Jane program from Roots & Shoots was found effective for the conservation leadership improvement even though the participants attended it with different motivations. The development of conservation leadership traits was facilitated by skills development, a supportive environment, and reflective action.

A new beef: An analysis of discourse coalitions in the nascent cellular agriculture policy subsystem
Abstract A robust approach to examining the nature and influence of coalitions in the policy process is the Advocacy Coalition Framework (ACF), which is especially useful to study policy issues fraught with scientific and technical controversy. Yet, important gaps exist in ACF literature regarding nascent policy subsystems. Consequently, there is scant

ABSTRACT Despite the high prevalence of cervical and breast cancer, screening rates remain low in low‐income countries. Using nationally representative data, we examine factors associated with knowledge and uptake of cervical and breast cancer screening among married women ages 30–49 in Nepal.

微团聚体是土壤团粒结构的基本组成单元,较大团聚体具有更强的稳定性,其形成与稳定对于土壤有机碳的长期吸存起着决定性作用。目前关于微团聚体形成与稳定性的研究多专注于农业土壤,红壤侵蚀地植被恢复后土壤团聚体稳定性、有机碳分布及微生物群落特征研究也主要集中在大团聚体上,而土壤微团聚体的动态变化及其主要影响因素尚不明确,对于其内在机制更缺乏了解。通过总结土壤微团聚体的形成过程及稳定性,综述了凋落物、根系和菌根对土壤微团聚体形成与稳定的影响,阐述了土壤微团聚体内微生物群落 ...

Trump, Personalism, and US Administrative Capacity
ABSTRACT Donald Trump represents an extraordinary degree of personalism in American politics, especially given the traditional power and capacity of the Republican Party and American democracy. A lesson Trump drew from his first term in office is that he needed to better institutionalize mechanisms of personal loyalty to deal with perceived betrayals ...

通过田间小区试验,研究了不同油菜种植密度与施氮肥对麦茬复种饲料油菜耕层(0~20cm)土壤颗粒组成、水稳性团聚体、微团聚体、粘粒分散率和团聚度的影响。试验结果表明,麦茬复种油菜能提高耕层土壤水稳性团聚体,改善土壤颗粒组成状况;与对照(CK)相比,耕层土壤粘粒分散率呈显著或极显著性降低,〈0.001mm的土壤团聚体破坏率和特征微团聚体比例(〈0.01mm/〉0.01mm)显著降低,而土壤团聚度在油菜苗期为降低趋势,收获期呈显著或极显著性增加,〉0 ...

Institutions, in time: Designing feedback pathways for shared infrastructure transitions
Abstract Electric utilities, challenged by a rapidly unfolding energy transition, use many informal institutions to bridge across technologies and sectors. Little is known, however, about how electric utility systems and other polycentric systems' institutions‐in‐use vary and evolve over time.

为探讨不同恢复方式对大兴安岭重度火烧迹地土壤团聚体形成及其团聚体碳循环的影响,以大兴安岭1987年重度火烧后分别经过人工恢复(兴安落叶松、樟子松)和天然恢复的林分为研究对象,分析不同恢复方式下土壤团聚体有机碳、团聚体微生物量碳和团聚体K2SO4浸提碳的分布特征。结果表明:(1)不同林型间土壤团聚体有机碳含量、团聚体微生物量碳含量和团聚体K2SO4浸提碳含量差异显著(P<0.05),其大小关系均是兴安落叶松人工林>天然次生林>樟子松人工林。(2)在不同植被恢复方式下 ...

How Patterns of Democracy Impact Policy Processes: When Lijphart and Sabatier Meet
ABSTRACT Policy process theories and institutional theories are two foundational strands in political science, both concerned with how people engage in politics. However, they differ in their focus, with policy process theories emphasizing the roles of actors, while institutional theories concentrate on the structures in which these actors are embedded.
