新能源汽车产业的政策保护与利基构建——基于多层次产业演化的分析

依据产业演化观点,将新能源汽车视为是在原有交通运输体系中出现的利基,探究社会技术体系的转变和产业政策的保护性作用对新能源汽车利基演化的影响。研究结果表明,在利基层次上,存在着新能源汽车技术利基向市场利基的演化过程,且技术利基宽度与市场利基宽度显著正相关。在社会技术体系层次上,一方面产业政策所形成的保护性空间有助于新能源汽车技术转化,另一方面反映社会技术转变的因素对新能源汽车利基的形成具有显著影响,其中新能源汽车产销比和废气治理投入与市场利基的形成负相关,而燃油价格、消费者购买力和基础设施建设水平与市场利基的形成正相关。据此提出根据产业演化阶段和层次设计产业政策的思路和方案。     

Ecological principle meets cancer treatment: treating children with acute myeloid leukemia with low-dose chemotherapy

Standard chemotherapy regimens for remission induction of pediatric acute myeloid leukemia (AML) are associated with significant morbidity and mortality. We performed a cohort study to determine the impact of reducing the intensity of remission induction chemotherapy on the outcomes of selected children with AML treated with a low-dose induction regimen plus granulocyte colony stimulating factor (G-CSF) (low-dose chemotherapy (LDC)/G-CSF). Complete response (CR) after two induction courses was attained in 87.0% (40/46) of patients receiving LDC/G-CSF. Post-remission therapy was offered to all patients, and included standard consolidation and/or stem cell transplantation. During the study period, an additional 94 consecutive children with AML treated with standard chemotherapy (SDC) for induction (80/94 (85.1%) of the patients attained CR after induction II, P = 0.953) and post-remission. In this non-randomized study, there were no significant differences in 4-year event-free (67.4 vs. 70.7%; P = 0.99) and overall (70.3 vs. 74.6%, P = 0.69) survival in the LDC/G-CSF and SDC cohorts, respectively. After the first course of induction, recovery of white blood cell (WBC) and platelet counts were significantly faster in patients receiving LDC/G-CSF than in those receiving SDC (11.5 vs. 18.5 d for WBCs (P < 0.001); 15.5 vs. 22.0 d for platelets (P < 0.001)). To examine the quality of molecular response, targeted deep sequencing was performed. Of 137 mutations detected at diagnosis in 20 children who attained hematological CR after two courses of LDC/G-CSF (n = 9) or SDC (n = 11), all of the mutations were below the reference value (variant allelic frequency <2.5%) after two courses, irrespective of the treatment group. In conclusion, children with AML receiving LDC/G-CSF appear to have similar outcomes and mutation clearance levels, but significantly lower toxicity than those receiving SDC. Thus, LDC/G-CSF should be further evaluated as an effective alternative to remission induction in pediatric AML.     

近代方志印数考

一些印刷数量的信息在近代方志中相对容易被找到,从这些信息中我们可以了解到:晚清每种雕版印刷的新修方志印数多为二三百部,民国每种采用新技术印刷的新修方志印数多为五六百部,重印旧方志的印数可能比同时期新修方志的印数少。总的来讲,近代每种新修方志的印数主要稳定在几百部,下至几部、几十部,上至千部、几千部的情况较少。这种现象的产生可能是由于方志的特殊性质、方志的稳定读者群小、缺乏印刷经费、志书价格高、印刷技术限制等原因造成的。     

我国体育用品制造业转型升级与服务业发展的关系研究

采用中国大陆东部、中西和西部三大经济区2008—2015年的面板数据，运用Johanson面板协整关系检验、Granger因果关系检验与面板数据误差修正模型，实证检验了我国体育用品制造业升级与服务业发展之间的因果关系。研究结果表明：不管是东部经济发达地区，还是中西部经济落后地区，体育用品制造业升级和服务业发展之间的协同互动关系均未建立起来，三大经济区体育用品制造业升级与服务业发展之间仅存在单向的因果关系。在东西部经济区，体育用品制造业升级是服务业发展的长期原因，但在中部经济区，服务业发展则是体育用品制造业升级的长期原因。从整体来看，虽然中国是一个体育用品制造和出口大国，但由于缺乏核心技术，产品全球竞争力较弱，国际话语权仍非常有限，与国内服务业发展相比，三大经济区体育用品制造业发展还处于相对较低的水平。最后，从互补性视角提出我国体育用品制造业与服务业发展的战略举措。     

Traffic Light Cards: a Cross and Modification Between the Minute Paper and Muddiest Point

Muddiest point and minute paper have been popular techniques to obtain feedback from students. However, focusing on the muddiest point too often can be discouraging for both students and instructors; in minute paper, students may often have off-topic comments. Here a cross and modified technique, the ‘traffic light’ card is introduced, to overcome the drawbacks in muddiest point and minute paper. About 2?minutes before the end of lecture, students “traffic light” the given topics on a notecard, in which their understanding is high (green), partial (yellow), or low (red). The results are used by the instructors to give appropriate review in the next lecture and help students gain better understanding in the content.     

日语教学新模式探讨

在新时期发展的中国正步入全球经济迅速发展的行列,国家间的文化交流日益倾繁,探究的深度也在不断提高,所以各高校应培养出更多优秀的复合型与善于交流的国际型人才[1]。中日交流作为国际交流的一部分,当今的日语教育不再是单纯的语言教学,更多是以语言为基拙的多元化综合性跨文化交流教学。采取新的日语教学模式,关系培养学生跨文化交际能力是新时期日语教育中的一个重点,影响中日未来的发展,具有现实的社会意义。
