Toward an Ethical Rhetoric of the Digital Scientific Image: Learning From the Era When Science Met Photoshop     

Jonathan Buehl 《Technical Communication Quarterly》2014,23(3):184-206

Over the past two decades, scientific editors have attempted to correct “mistaken” assumptions about scientific images and to curb unethical image-manipulation practices. Reactions to the advent and abuse of image-adjustment software (such as Adobe Photoshop) reveal the complex relations among visual representations, scientific credibility, and epistemic rhetoric. Perelman and Olbrechts-Tyteca's model of argumentation provides a flexible system for understanding these relations and for teaching students to use scientific images ethically and effectively.  相似文献   

从翻译改写理论评析《七律·长征》英译——以许渊冲译本与斯诺译本为例     

谢晴韵 《教育教学论坛》2019,(17):86-88

勒菲弗尔的翻译改写理论认为赞助人、意识形态、诗学形态等方面对译者的翻译策略起关键作用。笔者以《七律·长征》的斯诺英译本以及许渊冲英译本,从上述理论出发,剖析两位译者的翻译操控与截然不同的翻译选择。  相似文献   

论文化对翻译的操控现象   总被引：1，自引：0，他引：1  

侯晶晶 《山西师大学报(社会科学版)》2001,15(1):113-118

本文借鉴西方操控学派的研究视角,结合文化学、心理学、社会学的理论成果,探讨文化对于翻译的多层面操控的原因及表现.其中,宏观文化因素包括文化交流的客观需要、文化的性质和水平、民族的文化心理结构和文化的稳定性,微观文化因素包括道德、宗教和学术传统及其发展水平.在目前的社会历史条件下,增强操控的积极作用之根本方法是在坚持主旋律的前提下倡导文化及翻译的多样性.  相似文献   

“操纵论”视角下甘肃旅游文本汉译英策略研究     

陆文 《巢湖学院学报》2021,(1)

勒菲弗尔的“操纵论”认为,翻译就是一种改写,改写就是一种操纵。所有的改写,无论其意图,都反映了某种意识形态和诗学。旅游文本的翻译也难免受到译者所处时代的意识形态和诗学的操纵。文章依据勒菲弗尔的“操纵论”,通过对甘肃景点介绍翻译案例的分析,探讨并总结归纳出基于“操纵论”的甘肃景点介绍旅游文本英译翻译策略,以期提高甘肃旅游文本的译文质量,为甘肃旅游文本翻译的理论研究和实践提供借鉴,进而推动甘肃旅游业发展。  相似文献   

对我国证券投资者投资行为的思考   总被引：4，自引：0，他引：4  

薛耀文 《中国软科学》2002,(2):36-38,105

本文认为，中国A股市场中的各个角色，为股价操纵提供了主观上的可能性；股市周围环境和条件为股价操纵提供了客观上的可能性；而投资机构在资金、技术、人才、信息等方面的优势，以及收益与成本和风险的极不对称性使操纵股价成为可能和必然。股票市场要清除操纵行为不但要靠自身市场的完善，更要看我国市场经济体制改革的进程。  相似文献   

内幕交易、股价操纵和大股东侵占效应——基于全流通时代定向增发事件研究     

谢琳  唐松莲  尹宇明 《科技管理研究》2011,(3)

通过对定向增发预案公告前后超额累计收益率与相对交易量的分析,发现我国定向增发预案公告前后存在严重的内幕交易和股价操纵行为.从定向增发前后日均超额收益与相对交易量、相对换手率变动来看,发现我国定向增发期间,存在流通股股本变动的现象,从流通股本变动的原因分析,我们发现50%的股本变动是由于股改产生的受限流通股解禁上市流通引起的,这证明了全流通时代存在大股东通过选择定向增发时机对中小股东及新股东进行利益侵占.  相似文献   

汉代督邮管窥     

史云贵 《信阳师范学院学报(哲学社会科学版)》2004,24(1):106-109

形成于西汉中叶的督邮监县制,当上承秦及汉初的"都吏循行"。督邮按部刺举,上至王侯、令长,下至乡亭有秩、豪强,无所不纠,而以监县长吏为要。此举标志着西汉已形成了郡县二级地方监察体制。初,督邮对郡守负责,与刺史无涉。但刺史在地方官化的过程中,逐渐左右了督邮。至东汉,郡县两级纵向垂直监察系统得以打通。两汉政治经济之大环境,督邮与郡守之关系,督邮自身之素质,是影响督邮监察效果的三个基本因素。  相似文献   

题目：遗传改造细菌基因组的策略：基因定点突变、基因失活和基因过表达     

Jian-zhong Xu  Wei-guo Zhang 《Journal of Zhejiang University. Science. B》2016,17(2):83-99

With the availability of the whole genome sequence of Escherichia coli or Corynebacterium glutamicum, strategies for directed DNA manipulation have developed rapidly. DNA manipulation plays an important role in understanding the function of genes and in constructing novel engineering bacteria according to requirement. DNA manipulation involves modifying the autologous genes and expressing the heterogenous genes. Two alternative approaches, using electroporation linear DNA or recombinant suicide plasmid, allow a wide variety of DNA manipulation. However, the over-expression of the desired gene is generally executed via plasmid-mediation. The current review summarizes the common strategies used for genetically modifying E. coli and C. glutamicum genomes, and discusses the technical problem of multi-layered DNA manipulation. Strategies for gene over-expression via integrating into genome are proposed. This review is intended to be an accessible introduction to DNA manipulation within the bacterial genome for novices and a source of the latest experimental information for experienced investigators.  相似文献   

Interactive sculpting of product shape based on constraint manipulation in virtual environment     

刘振宇  谭建荣 《浙江大学学报(A卷英文版)》2005,6(7):733-740

In product concept design, not only designers with professional CAD skills, but also final customers take part in the design and evaluation of product shape styling. Because customers usually lack surface modelling background and are not familiar with concrete operations of commercial CAD systems, it is difficult for them to express their change intentions of product shape through professional CAD tools if they are not satisfied with the current shape design. This paper puts forward a method for creating, dragging and manipulating constraint and load represented in form of icon entity in interactive sculpting of product shape in virtual environment. The method supports customers manipulation of sculpting constraints or loads on sculpting shapes in virtual reality interaction to control the deformation of product shape. Constraints management based on icon entity is similar to spline lofting operation that is familiar to engineers, so users do not need to know surface details or have any professional knowledge of surface modelling, by only using their physical and engineering experience, they can manipulate the sculpting of product shape intuitively.  相似文献   

中小学教师数据素养评价指标体系构建     

林秀清  杨现民  李怡斐 《中国远程教育(综合版)》2020,(2):49-56,75,77

教育数据在教育领域不断渗透,教师的数据素养水平对于有效利用教育数据、合理判断学生的行为具有重要影响。本研究旨在用德尔菲法构建中小学教师数据素养评价指标体系,为评估中小学教师数据素养提供参考依据。通过文献分析梳理中小学教师数据素养评价指标,选择相关领域专家12人,采用德尔菲法进行2轮专家意见征询,根据专家打分计算指标权重,形成中小学教师数据素养评价指标体系。问卷征询专家的积极系数为100%,专家权威程度均值为0.72,确定的一、二级指标重要性均值均大于4.00,变异系数均小于0.25,符合德尔菲法要求。最终形成了包含数据意识、数据知识、数据操控技能、数据应用能力、评价交流数据、数据思维6个一级指标和19个二级指标与40条具体内容的中小学教师数据素养评价指标体系。对46位教师进行小范围试用,验证了其科学性与可靠性,该评价指标体系可作为评价中小学教师数据素养发展水平的参考测量工具。  相似文献
