World Journal of Emergency Medicine 2024年第3期15卷 243-245页

作者： DilberÜçöz Kocaşaban Sertaçgüler Emergency Medicine clinic Health Sciences University Ankara Training and Research HospitalAnkara 06930Turkey

central venous catheterization(cVc) is an invasive procedure for administering fluids,nutrients,and drugs;monitoring central venous pressure;performing pulmonary artery catheterization;and placing transvenous pacemakers in intensive care units and all specialties,from anesthesia to emergency medicine,for the treatment of trauma and hemodynamically unstable pediatric and adult patients.[1,2]complications have been observed in more than 15% of patients who underwent ***,infectious,and thrombotic complications have been reported in 5%–19%,5%–26%,and 2%–26% of patients,respectively.[3] Malposition,on the other hand,is common in subclavian catheter insertion and is usually associated with an initially misplaced guidewire.[4]

基于合约、借方和贷方三方面特征设计农户民间放贷离散选择实验,依据陕西、山东两省289户农户实验数据,构建效用相互依赖模型考察农户民间放贷选择偏好的内在机理,采用Mixed Logit模型探究农户选择偏好及其异质性来源。研究结果表明,农户民间放贷选择中经济理性与道义理性偏好并存。其中,经济理性体现为农户偏好向亲戚或信用水平较高的借方放贷,农户手头资金紧张时放贷意愿减弱;道义理性体现为农户偏好向经济情况比自己差、曾与自己有过互动经历且用途为生活性应急需求的借方放贷,农户拒贷有压力时放贷意愿增强。进一步研究发现,农户民间放贷选择偏好存在异质性,表现为受教育程度会强化放贷农户经济理性偏好,家庭收入会强化放贷农户道义理性偏好,风险偏好型放贷农户的道义理性偏好更弱,而山东省放贷农户的经济理性和道义理性偏好均高于陕西省。
