A Tale of Two Programs? Stigma and Administrative Burdens in CHIP and Medicaid

open access: yesWorld Medical &Health Policy, Volume 18, Issue 1, March 2026.
ABSTRACT One contributing factor to undersubscriptions is administrative burdens. To explore whether program stigma affects attitudes about administrative burdens, a survey (N = 2204) was fielded to assess differences in attitudes about seven policies decreasing administrative burdens and two policies increasing administrative burdens.

水平荷载作用下半刚性连接组合梁框架承载能力极限状态验算方法

open access: yesJianzhu Gangjiegou Jinzhan, 2007
本文分析了半刚性连接组合梁框架的在水平荷载作用下的受力特性,提出了对于具有合理构造措施的半刚性连接框架,采用塑性分析方法进行在水平荷载作用下的框架整体极限承载能力、组合梁的承载能力及框架柱的承载能力验算。采用塑性分析方法可使设计计算工作量极大地降低,而且能给出较为安全和准确的分析结果,这可供半刚性连接框架的实际设计参考。

Contrasting light demands determine the coordination of plants' non‐structural carbohydrates and economic strategy over the range of solar spectral composition

open access: yesFunctional Ecology, Volume 40, Issue 2, Page 534-552, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Non‐structural carbohydrates (NSC) are critical mediators of plant adaptation to fluctuating light environments. They are tightly coordinated with plant economic strategy, that is, leaf economics spectrum (LES) and root economics spectrum (RES).

Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

Evidence for a fisher‐designed solution to manta and devil ray bycatch in tuna fisheries

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Bycatch in global tropical tuna purse seine fisheries represents a significant source of mortality for manta and devil rays (mobulids), which are globally threatened. Use of best handling and rapid release practices on purse seine vessels can substantially reduce mortality and improve vulnerability status for mobulids.

循环周转型临时看台支承架体重复对比试验研究

open access: yes
北京冬奥会为积极响应国家走绿色可持续发展道路,采用了大量支承架体用于临时看台或舞台的搭建。为研究赛后的临时看台支承架体能否安全合理地再次使用,本文以索氏不锈钢插销式节点临时看台支承架体为研究对象,设计并制作了一个2×2足尺模型,共进行了两次试验,即在首次水平加载试验结束后,将该试验架体搭建在室外经历长时间严寒风雪环境条件后再重复做一次试验,重点对比分析了其在4种不同恒载与水平荷载组合作用下的整体结构变形模式、力学性能及典型位置峰值应变等。研究结果表明:在恒载为0 kN⋅m-2、0.5 kN⋅m-2、2 ...
