管理层薪酬激励对企业创新水平的影响研究

企业创新水平是衡量当今企业是否能在日益激烈的竞争环境中生存和发展的重要指标。以创新水平为出发点,以2012—2017年沪深A股非金融保险类上市公司为样本,考察管理层薪酬对企业创新水平的影响。研究发现,管理层薪酬激励对企业创新水平具有显著正向作用。以研发投入和研发产出分别作为企业创新水平衡量指标,结果表明管理层激励对两者都具有正向影响。进一步研究发现,不同的行业性质、产权性质对企业创新投入与创新产出的影响不存在显著差异,而管理层是否持股的差异使得管理层薪酬激励对企业创新水平的正向作用产生显著差异。     

CT导向下125I粒子植入联合髂内动脉化疗灌注治疗难治性复发性盆腔恶性肿瘤疗效评价

【摘要】 目的 探讨CT导向下125I粒子植入联合髂内动脉化疗灌注治疗难治性复发性盆腔恶性肿瘤的临床疗效。方法 选自2013年1月至2016年1月采用CT导向下125I粒子植入联合髂内动脉化疗灌注治疗难治性复发性盆腔恶性肿瘤35例患者为治疗组，与单纯采用125I粒子植入治疗的该类患者39例为对照组，对两组的近、远期疗效和临床症状改善进行比较。结果 治疗组客观有效率60.0%（21/35），获益率85.7%（30/35）；对照组客观有效率53.8%（21/39），获益率84.6%（33/39），两组客观有效率及获益率差异均无统计学意义（P=0.594，P=0.894）；治疗组疾病无进展期平均12.2个月，对照组平均8.6个月，治疗组较对照组平均间隔时间延长了3．6个月，两组差异有统计学意义（P=0.002）；治疗组复发率40.0％（12/30），对照组57.6％（19/33），两组比较差异有显著统计学意义（P=0．018）。治疗组治疗前后KPS平均值为72．4分和82.7分，对照组为68．9分和79.1分，各组治疗前后临床症状改善差异有统计学意义（P=0.043，P=0.039），两组治疗后临床症状改善差异无统计学意义（P=0.745）。结论 对难治性复发性盆腔恶性肿瘤采用125I粒子植入是一种有效的治疗方案，但联合髂内动脉化疗灌注可以降低肿瘤复发，提高疾病无进展期。

Cross-task emotion recognition using eeg measures: first step towards practical application

Electroencephalographic (EEG)-based emotion recognition has received increasing attention in the field of human-computer interaction (HCI) recently, there however remains a number of challenges in building a generalized emotion recognition model, one of which includes the difficulty of an EEG-based emotion classifier trained on a specific task to handle other tasks. Little attention has been paid to this issue. The current study is to determine the feasibility of coping with this challenge using feature selection. 12 healthy volunteers were emotionally elicited when conducting picture induced and video induced tasks. Firstly, support vector machine (SVM) classifier was examined under within-task conditions (trained and tested on the same task) and cross-task conditions (trained on one task and tested on another task) for picture induced and video induced tasks. The within-task classification performed fairly well (classification accuracy: 51.6% for picture task and 94.4% for video task). Cross-task classification, however, deteriorated to low levels (around 44%). Trained and tested with the most robust feature subset selected by SVM-recursive feature elimination (RFE), the performance of cross-task classifier was significantly improved to above 68%. These results suggest that cross-task emotion recognition is feasible with proper methods and bring EEG-based emotion recognition models closer to being able to discriminate emotion states for any tasks.     

食物致敏原表位定位技术的研究进展

食物致敏原是引起食物过敏的元凶，多为蛋白质。抗原表位是在抗原分子中与抗体反应或被抗原受体识别，并引发机体免疫应答的特殊化学基团。从表位水平认识食物致敏原，能揭示食物过敏的物质基础，为解决食物过敏问题提供精准的靶标。本文基于表位结构和定位方法的不同，介绍了食物致敏原表位定位技术的发展，并进一步展望了致敏原表位信息对于改进食物过敏鉴定技术和低致敏食物加工方法的应用前景。     

Strengthening Mechanisms for Ti-and Nb-Ti-micro-alloyed High-strength Steels

The strengthening mechanisms of hot-rolled steels micro-alloyed with Ti (ST-TQ500)and Nb-Ti (NT-TQ500)were investigated by examining the microstructures of steels using optical microscope (OM),scanning elec-tron microscope (SEM)and transmission electron microscope (TEM).The results revealed almost no differences in the solute solution strengthening and fine-grained strengthening of the two steels,whereas the contributions of pre-cipitation strengthening and dislocation strengthening were different for ST-TQ500 and NT-TQ500.The measured precipitation strengthening effect of ST-TQ500 was 88 MPa higher than that of NT-TQ500;this difference was pri-marily attributed to the stronger precipitation effect of the Ti-containing nanoscale particles.The dislocation strengthening effect of ST-TQ500 was approximately 80 MPa lower than that of NT-TQ500.This is thought to be related to differences in deformation behavior during the finishing rolling stage;the inhibition of dynamic recrystalli-zation from Nb in NT-TQ500 (Nb-Ti)may lead to higher density of dislocations in the microstructure.
