CMS中四种色彩转换方式的比较

色彩管理系统(CMS)是目前彩色印刷技术的核心,它可以控制印刷系统中不同设备间的色彩传递与转换.色彩管理系统中所采用的ICC标准规定了四种色彩转换方式,它们分别为:等比压缩(Perceptual,也称为感性压缩)、饱和度优先(Saturation)、相对色度匹配(Relative Colorimetric)和绝对色度匹配(AbsoluteColorimetric).本文通过对四种色彩转换方式的输出结果进行测试,分析四种转换方式的差别.

工程服务中心:构建工程创新实践教育的支撑体系——上海交通大学国家双创示范基地案例分析

在高等工程教育中学生自主实践创新教学活动极为重要,而当前高校普遍缺乏创新支撑服务平台及灵活的实践服务模式,学生在自主开展实践教学活动时常常需耗费大量的时间和成本去完成创新项目所需资源的准备;一轮轮的教学实践环境建设,由于多围绕课程、学科的培养体系投入,造成设备利用率低,与学生强烈的创新实践需求形成尖锐矛盾。本文基于当前国家双创示范基地中学生创新中心建设,创造性提出以工具借出、设备借用、远程加工、设计IP撮合等为特点的特色服务模式,持续大量地为学生提供基本器具资源使用和加工服务。围绕学生需求提供"创新实践图书馆"式的服务,为学生创造创新实践的服务环境。本文就设备借出、3D打印等具体工程服务分中心建设的内容、目标和服务模式,阐述了这类创新实践服务中心的建设模式,需要解决的问题和实施思路。实践证明,建设工程服务中心能有效解决设备利用率问题,更好地培养大规模勇于投身实践的创新人才,为高校创新人才培养模式开辟新途径。     

问题式教学法对工科大学生批判性思维倾向影响的实证研究

采用不相等实验组对照组前后测准实验研究,并辅以行为观察数据和质性资料分析,探究在"基本电路理论"课程教学中采取问题式教学法促进工科大学生批判性思维倾向的发展。研究表明,问题式教学对工科大学生的批判性思维倾向有显著的促进作用。作者认为,为有效开展问题式教学以促进学生批判性思维发展,应注意:(1)教师需具备良好的批判性思维精神;(2)积极营造良好的思考情境和氛围,鼓励与引导学生发现和解决问题;(3)应根据学生基础设置难易适当的问题,营造问题讨论的安全教学氛围;(4)积极引导讨论小组确定合适的讨论问题和组内讨论规则,充分利用信息技术辅助教学。     

Four pitfalls in normalizing citation indicators: An investigation of ESI’s selection of highly cited papers

InCites Essential Science Indicators is becoming increasingly used to identify top-performing research and evaluate the impact of institutes. Unfortunately, our study shows that ESI indicators, as well as other normalized citation indicators, have the following flaws. First, the publication month and the online-to-print delay affect a paper’s probability of becoming a Highly Cited Paper (HCP). Papers published in the earlier months of the year are more likely to accumulate enough citation counts to rank at the top 1% compared with those published in later months of the year. Papers with longer online-to-print delays have an apparent advantage for being selected as HCPs. Research field normalizations lead to the third pitfall. Different research fields have different citation thresholds for HCPs, making research field classification important for a journal. In addition, the uniform thresholds for both articles and reviews in ESI affect the reliability of HCP selection because, on average, reviews tend to have higher citation rates than articles. ESI’s selection of HCPs provides an intuitive feel for the problems of normalized citation impact indicators, such as those provided in InCites and SciVal.     

唐君毅先生之船山人性论浅释(下)——探《船山之尊生尊气与尊情才义》

唐先生认为,船山的两端一致说,肯定气禀,认为恶的来源不在于欲求,而在欲求的不中节,以情才之交的不当位而下流。耳目口鼻与欲求,不是吾人当该舍弃的对象,而是当吾人把情才之交,流荡而为机械式,下委而不能中节所造成的。故唐先生对船山论气质与恶的关系所作诠释发挥了船山重气的义理,视气是可以保住的,重点在于别低贱气,独尊性,因性为孤立,如此则否定世间气化,而且情才也要依于性善的引导,才能不流于恶。     

Simultaneous changes in seed size,oil content and protein content driven by selection of SWEET homologues during soybean domestication

Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed. Soybean domestication involved parallel increases in seed size and oil content, and a concomitant decrease in protein content. However, science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes. Here, re-sequencing data from >800 genotypes revealed a strong selection during soybean domestication on GmSWEET10a. The selection of GmSWEET10a conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content. The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans. Moreover, GmSWEET10b was found to be functionally redundant with its homologue GmSWEET10a and to be undergoing selection in current breeding, leading the the elite allele GmSWEET10b, a potential target for present-day soybean breeding. Both GmSWEET10a and GmSWEET10b were shown to transport sucrose and hexose, contributing to sugar allocation from seed coat to embryo, which consequently determines oil and protein contents and seed size in soybean. We conclude that past selection of optimal GmSWEET10a alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEET10b may further improve the yield and seed quality of modern soybean cultivars.
