联合指导目前已经成为博士生学术指导的一种重要形式。但和传统的单一导师制相比,联合指导制度的效果具体如何,相关的实证分析较为不足。本研究基于2021年全国博士离校调查数据,通过回归分析、异质性分析、拉索回归调整等研究方法,分析了联合指导制对于博士生研究产出和能力发展评价的学科异质性影响。研究发现,导师指导形式是博士生培养质量的重要影响因素,相较于传统的单一导师制,联合指导制对博士生的研究产出、能力发展发挥了显著的积极影响。在进一步的学科异质性分析中,结果表明在理学、工学、医学中,联合指导制的实施显著提高了博士生的研究产出和能力发展水平;在农学和社会科学中,联合导师制的影响只体现在能力发展方面;而在人文学科中,联合指导制对论文产出和能力发展均无显著影响。基于上述实证结论,研究建议在理工医等学科中进一步推广联合指导制度。

We develop a new ultrastrong medium Mn steel with a density reduced to 7.39 g cm^(-3).It has a novel tri-phase microstructure comprising a hierarchical martensitic matrix(α’),dispersed ultra-fine-retained austenite grains(γ),and both compressed and{200}orientedδ-ferrite lamellas,the latter’s formation is due to the alloying of high Al and Si contents for reducing *** a result,both ultrahigh ultimate tensile strength of 2.1 GPa and good ductility of 16%are achieved after an extraordinary plastic strain hardening increment of about 1.4 *** in-situ synchrotron-based high-energy(HE)X-ray diffraction(XRD)examinations during the tensile deformation revealed that the initial presence of residual com-pressive stress inδ-ferrite could increase the stress required to initiate the plastic tensile deformation of the specimen,leading to the isolatedδ-ferrite lamellas mostly deformed elastically to coordinate the plastic deformation of the martensitic matrix during *** the plastic deformation,the gradual release of residual compressive stress inδandα’,the dislocation multiplication in all the three phases and the successiveγ-to-α’transformation all contribute to such a prominent work hardening *** study facilitates the development of novel strategies for fabricating ultrastrong but light steels.

目的:探索早发性前列腺癌的临床病理特征;建立并验证年轻男性前列腺穿刺结果的预测模型。方法:回顾性分析2011—2021年在四川大学华西医院行前列腺穿刺活检术的213例≤50岁男性的临床影像资料,以探索与早发性前列腺癌发生相关的预测因素。美国SEER数据库中4608例同时期早发性前列腺癌患者的数据被获取,并用于比较东西方早发性前列腺癌患者的临床病理差异。129例具有基于多参数磁共振成像(multi-parametric MRI,mpMRI)的前列腺影像报告和数据系统(prostate imaging reporting and data system,PIRADS)评分及表观弥散系数(apparent diffusion coefficient,ADC)值的患者被随机分配至训练组(91例)和验证组(38例),分别用于早发性前列腺癌预测模型的构建和验证。单因素和多因素logistic回归分析被用于模型建立。模型通过列线图进行可视化展示并通过受试者工作特征(receiver operating characteristic,ROC)曲线、校准曲线以及决策曲线分析进行验证。结果:本研究所纳入患者的中位年龄为46岁。最终46例(21.6%,46/213)检出前列腺癌。相较SEER数据库人群,本中心的早发性前列腺癌患者具有显著更高的中位前列腺特异性抗原(prostate-specific antigen,PSA)(14.2 ng/mL vs 5.7 ng/mL,P<0.001)、初诊骨转移占比(34.1%vs 4.6%,P<0.001)以及国际泌尿病理学会(International Society of Urological Pathology,ISUP)4~5级占比(46%vs 8%,P<0.001)。多因素logistic回归分析结果显示,年龄(OR=1.323,95%CI:1.111~1.649,P=0.005)、前列腺特异性抗原密度(PSAD)(OR=1.718,95%CI:1.058~3.108,P=0.038)、PIRADS 4分(OR=26.632,95%CI:3.572~584.050,P=0.006)、PIRADS 5分(OR=46.789,95%CI:5.548~1[KG0.5mm]107.801,P=0.002)以及ADC值(OR=0.995,95%CI:0.991~0.999,P=0.021)是早发性前列腺癌的独立预测因素。上述临床影像参数被用于预测模型的构建。在内部验证中,模型的ROC曲线AUC值为0.842。在校准曲线以及决策曲线分析中,模型亦具有良好表现。结论:本研究构建了预测年轻男性罹患早发性前列腺癌的模型,若能在未来大样本的外部队列中得到有效验证,这一模型将有望成为辅助前列腺穿刺抉择的工具。
