Introduction to the International Symposium on Lipid Science and Health and research progress in lipid science and health

The International Symposium on Lipid Science and Health (ISLSH), which was organized annually by Oil Crops Research Institute of Chinese Academy of Agricultural Sciences (OCRI-CAAS) since 2016, has gained a strong reputation and attracted hundreds of delegates from around the world for discussion of lipid research trends and advances every year, to promote research and academic exchanges in the fields of lipid science and health. The 5th International Symposium on lipid Science and Health was successfully held in Wuhan, China, from October 23rd to 25th, 2020, to celebrate the 60th anniversary of OCRI-CAAS. The two-day symposium gathered well-known experts specialized in lipid science to share the current state of lipid research with emphasis on aspects covering: (1) lipid profiling and characterization, (2) lipid preparation and modification, (3) lipid improvement and regulation, and (4) lipid nutrition and health. The symposium was conducted by a combination of on-site and network meeting. More than 250 distinguished delegates from academia and industry participated in the on-site multidisciplinary meeting, and thousands of scholars attended the virtual event. This paper is as a record of the symposium proceedings and a brief summary of the advances and trends in 4 aspects of lipid science and health.     

大数据背景下高职院校数据素养教育研究——基于广东省科技干部学院商科学生的抽样调查

[目的/意义]针对高职数据素养教育缺位的现状,以师生对数据素养的认知情况为培养现状的分析依据,为高职院校建立科学合理的数据素养培养体系、建设相应的课程体系、合理分配有限教学资源提供参考。[方法/过程]基于已有的数据素养指标体系,构建高职院校数据素养评价体系,采用问卷的方式调查高职学生的数据意识、数据收集、数据组织与管理、数据分析、数据利用与归档、数据伦理6个方面的认知与能力,结合文献提出“三阶递进”式的高职数据素养教育体系。[结果/结论]师生总体具备一定的数据意识,但对商业数据的有效获取能力比较缺乏。具备基础的数据分析能力及表达能力,数据价值的深度挖掘能力不足。数据收集、组织与管理、分析、利用与归档能力认知在群体间的差异明显,认为应从“底层-进阶-高级”3个层次进行教育体系的设计,提升数据素养综合能力。     

通往数字人才强国之路：《提升全民数字素养与技能行动纲要》与大学生数字素养教育战略

[目的/意义]提升大学生数字素养对建设数字人才强国具有重要意义。[方法/过程]文章梳理了《提升全民数字素养与技能行动纲要》发布前后的相关政策,分析了《行动纲要》在当前背景下出台的独特作用,认为该文件确定了具有中国特色和国际视野的数字素养概念;关注了创造力提升、特殊群体服务等前沿要求;拓展出生活、工作、学习、创新四大数字场景;围绕重点任务和工程部署了全面行动。[结果/结论]作者认为,对图情档各个理论与实践领域而言,《行动纲要》的影响将是广泛的,但按照信息素养的研究格局和传统,其对大学生数字素养教育的影响或许最为直接和深远,应当尽快针对围绕大学生数字素养教育展开布局和行动。     

Determination of critical nitrogen dilution curve based on leaf area index for winter wheat in the Guanzhong Plain,Northwest China

Excessive use of nitrogen(N) fertilizers in agricultural systems increases the cost of production and risk of environmental pollution. Therefore, determination of optimum N requirements for plant growth is necessary. Previous studies mostly established critical N dilution curves based on aboveground dry matter(DM) or leaf dry matter(LDM) and stem dry matter(SDM), to diagnose the N nutrition status of the whole plant. As these methods are time consuming, we investigated the more rapidly determined leaf area index(LAI) method to establish the critical nitrogen(N_c) dilution curve, and the curve was used to diagnose plant N status for winter wheat in Guanzhong Plain in Northwest China. Field experiments were conducted using four N fertilization levels(0, 105, 210 and 315 kg ha-1) applied to six wheat cultivars in the 2013–2014 and 2014–2015 growing seasons. LAI, DM, plant N concentration(PNC) and grain yield were determined. Data points from four cultivars were used for establishing the N_c curve and data points from the remaining two cultivars were used for validating the curve. The N_c dilution curve was validated for N-limiting and non-N-limiting growth conditions and there was good agreement between estimated and observed values. The N nutrition index(NNI) ranged from 0.41 to 1.25 and the accumulated plant N deficit(N_(and)) ranged from 60.38 to –17.92 kg ha~(-1) during the growing season. The relative grain yield was significantly affected by NNI and was adequately described with a parabolic function. The N_c curve based on LAI can be adopted as an alternative and more rapid approach to diagnose plant N status to support N fertilization decisions during the vegetative growth of winter wheat in Guanzhong Plain in Northwest China.
