BACKGROUND Extensive research revealed the absence of reports documenting hypertensive emergencies precipitated by changes in the cervical spine *** SUMMARY We here present a 57-year-old woman diagnosed as having cervical spondylotic radiculopathy(CSR)who was scheduled for anterior cervical decompression and *** post-anesthetic positioning,a sudden hypertensive surge was observed when the patient was in a supine position with the neck being slightly *** surge was promptly reversed through cervical flexion and head *** event however required an alternate surgical approach for recovery—posterior laminoplasty and endoscopy-assisted nucleus pulposus *** the 6-month outpatient follow-up period,cervical flexion and extension activities substantially improved in the patient without any episodes of increase in acute blood *** Maintaining a safe hypotensive posture and performing rapid,thorough deco-mpression surgery may serve as effective interventions for patients presenting symptoms similar to those of CSR accompanied by hypertensive emergencies(HE).This would mitigate the underlying causes of these HEs.

本文提出了一种基于环形阵列的空间滤波器结构损伤扫描监测方法,在结构中央布置环形压电传感器阵列实现对结构的全方位扫描监测,消除了主动Lamb波空间滤波器监测方法中盲区及远场对监测效果的影响。环形阵列由直径方向不同角度的4个线阵组成,每个线阵采用主动Lamb波空间滤波监测方法对结构损伤进行监测、成像,各阵列成像结果通过PCA-小波变换进行融合对损伤位置进行判别,从而实现结构全方位损伤扫描监测,消除单个阵列损伤监测的盲区、远场及虚假成像等影响,进而获得更加准确的损伤监测结果。通过实验研究,验证了该方法的有效性和实用性。

集团公司差异化管控能够优化不同出资主体的权力配置,然而集团公司管控现有研究对有限理性的默认假设缺乏关注,无法为集团公司差异化管控提供理论支持。本文基于不完全契约理论,指出集团公司差异化管控的底层逻辑是实际控制人、子公司其他股东和子公司高管围绕关键资源禀赋、子公司对集团公司的重要程度和依赖程度等影响因素进行剩余控制权优化配置。同时,剩余控制权配置过程会产生异质性配置结果,进而产生不同的管控模式和代理问题,这就需要辅以异质性治理结构与机制安排,以降低潜在治理成本。本文通过解构上述过程,主要回答了集团公司差异化管控的底层逻辑、分类依据和治理对策等三个核心命题,不仅可以助力集团公司差异化管控实践,还能够为完善中国特色现代企业制度、弘扬企业家精神提供有益启示。
