訪問看護師の倫理的問題に関連するストレス認知尺度の妥当性と信頼性 [PDF]
, 2020 訪問看護師の倫理的問題に関連するストレス認知を測定する尺度を開発し、その構成概念妥当性と信頼性を検討することを目的に、訪問看護師を対象に自記式質問紙調査を行った。分析対象は182名であった。訪問看護師の倫理的問題に関連するストレス認知はJametonの倫理的問題の分類を基に5因子を準備し、二次因子モデルからなる尺度を開発した。分析では、このモデルのデータへの適合性を確認的因子分析で検討した。この結果、CFI=0.938、RMSEA=0.062であり、適合度指標は統計学許容水準を満たした ...

Optimal Banking Contracts with a Continuum of Types [PDF]
, 2013 本稿では，銀行が企業と貸付契約を締結する際に，すでに企業が私的情報を保有している状況における最適契約設計の問題を分析した．最も効率的なタイプの企業の借入額は自らのファーストベストの水準に一致するが，このタイプ以外の企業の借入額は自らのファーストベストの水準を下回るという意味で一種の信用割当を受ける．また，最も非効率的なタイプの企業は留保効用に等しい効用を得るに過ぎないが，しかし，このタイプ以外の企業は留保効用を上回る情報レントを獲得する．しかも ...

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响
Conservation Biology, EarlyView.Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...

A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership
