基于资源基础理论,聚焦企业韧性的稳定性和灵活性特征,探讨数字化变革背景下技术多元化与企业韧性的关系。利用2018~2022年新冠疫情冲击前后中国上市高新技术企业的数据,采用OLS回归和生存分析法进行实证分析。结果表明:非相关技术多元化和相关技术多元化均与企业受到冲击后的稳定性呈倒U型关系;非相关技术多元化负向影响企业受到冲击后的灵活性,而相关技术多元化正向影响企业受到冲击后的灵活性;数字化变革加强了相关技术多元化与企业受到冲击后稳定性间的倒U型关系,并削弱了非相关技术多元化对企业受到冲击后灵活性的抑制作用。研究结论丰富和拓展了技术多元化与企业韧性的相关研究,为企业制定合适的技术多元化战略以增强韧性提供参考。

目的探讨多学科诊疗模式(MDT)应用于动静脉内瘘(AVF)假性动脉瘤患者的效果。方法选取2021年11月—2023年1月医院收治的137例AVF假性动脉瘤患者作为研究对象,按照组间基本特征具有可比性的原则分为对照组68例和观察组69例。对照组给予常规护理,即在患者入院后予以健康指导,提高患者的疾病认知度,并依据其透析情况及时进行干预,护士在做好穿刺评估后可采用跳跃式或绳梯式穿刺方法,成功后进行透析,结束后利用纱布加压止血。观察组在多学科诊疗模式基础上组建内瘘专项小组,建立患者健康档案进行分类及分层管理,小组成员通过语言及示范等多种方式在透析前后进行健康宣教,透析时选用适合的血管进行穿刺并依据患者血检报告调整止血时间,依据患者具体情况制订外科治疗方案。观察两组自我护能力,穿刺次数及瘤体情况,生活质量,并发症发生率。结果干预3个月后,观察组自我护理技巧、自我概念、健康知识水平及自我护理责任感评分均高于对照组,差异有统计学意义(P<0.05);观察组平均穿刺次数及瘤体个数均少于对照组,观察组瘤体较对照组小,差异有统计学意义(P<0.05);干预3个月后,观察组KDQOL-SFTM量表中SF-36总分及肾病和透析相关生存质量量表总分均高于对照组,差异有统计学意义(P<0.05);观察组并发症发生率低于对照组,差异有统计学意义(P<0.05)。结论与单一接受常规护理比较,对AVF假性动脉瘤患者予以MDT模式可减少穿刺次数,提高自我护能力,降低并发症发生率。

The importance of enhancing sludge dewaterability is increasing due to the considerable impact of excess sludge volume on disposal costs and on overall sludge management. This study presents an innovative approach to enhance dewaterability of anaerobic digestate（AD） harvested from a wastewater treatment plant. The combination of zero valent iron（ZVI, 0–4.0 g/g total solids（TS）） and hydrogen peroxide（HP, 0–90 mg/g TS） under pH 3.0 significantly enhanced the AD dewaterability. The largest enhancement of AD dewaterability was achieved at 18 mg HP/g TS and 2.0 g ZVI/g TS, with the capillary suction time reduced by up to 90%. Economic analysis suggested that the proposed HP and ZVI treatment has more economic benefits in comparison with the classical Fenton reaction process. The destruction of extracellular polymeric substances and cells as well as the decrease of particle size were supposed to contribute to the enhanced AD dewaterability by HP ＋ ZVI conditioning.

人脸身份信息的提取方式一直是人脸研究中颇有争议的问题之一,以往的研究通过对名字和职业等语义信息的提取速度差异的比较,对此问题提出了两类观点,即人脸身份信息的加工是系列加工或平行加工。这两种观点一直争论不休,一些研究者提出了各种理论试图解释二者的争论。但是人脸身份信息中包括类别信息和特定信息,二者的加工可能是不同的路径,而以往的研究却混淆了这两种身份信息,使得系列还是平行的争议建立在不同的层面上。本研究通过操纵提取身份信息的不同任务以及线索类型,比较人脸和名字的作业差异,从而探讨两种类型身份信息的加工机制。本研究有助于进一步了解人脸身份信息提取的机制,丰富人脸身份信息提取的理论研究,同时对模式识别也具有重要的实践意义。

以啤酒酵母为原料提取β-葡聚糖,并用β-葡聚糖作为脂肪替代品替代重油蛋糕配方中的部分脂肪,研究加入β-葡聚糖对重油蛋糕理化参数,质构以及感官评定的影响。结果表明,蛋糕中的水分含量随着蛋糕中脂肪含量的减少而增加。β-葡聚糖的加入使重油蛋糕的弹性、胶着性和回复性均有所增加,同时改善了重油蛋糕的咀嚼性。感官评定表明,加入20%脂肪替代品的蛋糕感官指标与传统重油蛋糕较为接近。
