The Problem With Problem Load: Reconceptualizing Load in the Multiple Streams Framework
Review of Policy Research, Volume 43, Issue 6, November 2026.ABSTRACT What happens when policymaking systems buckle under pressure, disrupting consensus and stalling decision‐making? Drawing on the Multiple Streams Framework, we show that the existing concept capturing this stress, Problem Load, has been both misinterpreted and overstretched.

くるめサマートリートメントプログラムの効果―注意欠陥多動性障害のある超低出生体重児の事例― [PDF]
, 2011 超低出生体重児でADHDがある児童のSTP参加の症例である。本児の生活上の問題は，超低出生体重児で生まれたことから親の養育態度が保護的であったが，幼稚園までは園の先生から落ち着きがないという指摘だけであった。しかし，小学校入学後は，学校の準備や日常生活の中での不注意が表 面化してきた。忘れ物が多く，友人関係も仲良しができない状況であった。STPに参加し注意の集中と自分で行動することが可能になった。また，保護者もペアレントトレーニングで本児の接し方を学ぶことで対応できるようになった ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The deformation behavior of NiTiNb shape memory alloys is governed by microstructural heterogeneity, specifically the interconnected topology of the β‐Nb phase. The regulatory role of the eutectic structure in load partitioning and the evolution of deformation mechanisms, particularly in high‐Nb systems, has not been clearly understood.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Aqueous Zn‐ion batteries (AZIBs) are expected to become one of the most promising candidates for large‐scale energy storage, but are impeded by uncontrollable dendrite growth and parasitic reactions. In this study, we propose a simple mechanical shot‐peening (SP) approach for restructuring commercial Zn foils into highly exposed (002)‐textured
