沙汀短篇小说研究的发展

自上世纪三十年代至今,沙汀短篇小说的研究大致经历了三个阶段:20世纪三四十年代带有强烈的政治色彩的批评;新时期到来至20世纪八十年代末注重系统地分析其艺术特征的审美批评;20世纪八十年代末至今叙事学、心理学等理论方法在沙汀短篇小说研究上的运用和在比较研究方面取得的成绩。纵览历史发展线索,扫描沙汀短篇小说研究的得失,并勾勒出其运动轨迹,不仅可以推动沙汀短篇小说研究向更深层次发展,也将有助于整个现代文学的研究。     

论迟子建中短篇小说中的“黑土地”意象

"黑土地"作为东北平原最珍贵的土壤,同时也是迟子建中短篇小说里主要意象。通过解读部分中短篇小说,以此来剖析"黑土地"这一意象里乡村人与都市人对这一意象的依恋与崇尚。乡村人这一部分重点剖析"黑土地"对于乡村人所蕴含的物质、精神与生命三个层次上的丰富意义;都市人这一部分重点阐释他们在身体与灵魂里放逐自己,皈依土地。在乡村与都市这样一个二元对立系统里,"黑土地"这一意象贯穿其中,串联着乡村人与都市人对"黑土地"的眷恋。     

小学语文阅读教学渗透长文短教设计思路——以《美丽的小兴安岭》教学为例

近几年来,小学语文教材中一些篇幅较长的课文常常被冠以"长文"的头衔,其主要特点为文字多,教学用时长,重难点难以把握等,一直困扰着一线的语文教师们。怎样做到长文短教,化繁为简呢?文章以《美丽的小兴安岭》为教学案例,分析小学语文阅读教学应如何渗透长文短教的设计思路。     

继电保护运行管理中"短板"现象的消除

从最近几年的继电保护事故的简要分析,结合日常运行管理经验,总结提高继电保护运行管理水平,提出运行全过程管理中的薄弱环节,进行短板分析,并给出相应的解决办法从而消除短板。     

校报要让短稿唱主角

当前高校校报普遍存在着长稿偏多的现象，根据高校校报自身的任务和特点，应该在刊载字数、版面安排，写作方法等方面采取措施多采用短稿，以加大信息承载量。     

"文学不等于一般的宣传"——关于建国初期丁玲对教条主义的批判

建国初期,在文学成为政治工具的时代,教条主义几乎成了文学创作中的顽症.为了纠正文学创作中的不良倾向,丁玲不但富有胆识地提出了文学创作中所存在的"教条主义"的问题,而且侧重从主题题材、形象塑造和文学功用等方面对文学创作中教条主义的表现和公式化、概念化的成因做出了相当深入的挖掘和剖析,切中时弊,表现了"战胜教条主义"的努力.丁玲对教条主义的批判,既与50年代外在文学情势的变化相关,更关乎其对"五四"文学传统的理解和固守.     

“被”字句的派生问题研究

回顾以往对汉语的“被”字句派生问题的研究,发现相关文献中对“被”字句的假设存在不少问题,文章提出将“被”分析为《最简方案》框架下的次动词的假设,“被”字句通过“被”字的移位而生成,长短被字句以同一模式生成,两者具有类似的句法结构,其派生可通过次动词的基本特征来解释。     

宋初小令词坛浅议

宋初小令主要继承唐五代词风的余绪,其一方面强化了唐五代文人开创、定型的创作范式,进一步确立了“本色”词的主流地位,另一方面,也为宋词鼎盛时期的到来,起到了“导夫先路”的作用。     

CRISPR/Cas: a Nobel Prize award-winning precise genome editing technology for gene therapy and crop improvement

Since it was first recognized in bacteria and archaea as a mechanism for innate viral immunity in the early 2010 s,clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein(Cas) has rapidly been developed into a robust, multifunctional genome editing tool with many uses. Following the discovery of the initial CRISPR/Cas-based system, the technology has been advanced to facilitate a multitude of different functions. These include development as a base editor, prime editor, epigenetic editor, and CRISPR interference(CRISPRi) and CRISPR activator(CRISPRa) gene regulators. It can also be used for chromatin and RNA targeting and imaging. Its applications have proved revolutionary across numerous biological fields, especially in biomedical and agricultural improvement. As a diagnostic tool, CRISPR has been developed to aid the detection and screening of both human and plant diseases, and has even been applied during the current coronavirus disease 2019(COVID-19) pandemic. CRISPR/Cas is also being trialed as a new form of gene therapy for treating various human diseases, including cancers, and has aided drug development. In terms of agricultural breeding, precise targeting of biological pathways via CRISPR/Cas has been key to regulating molecular biosynthesis and allowing modification of proteins, starch, oil, and other functional components for crop improvement. Adding to this, CRISPR/Cas has been shown capable of significantly enhancing both plant tolerance to environmental stresses and overall crop yield via the targeting of various agronomically important gene regulators. Looking to the future, increasing the efficiency and precision of CRISPR/Cas delivery systems and limiting off-target activity are two major challenges for wider application of the technology. This review provides an in-depth overview of current CRISPR development, including the advantages and disadvantages of the technology,recent applications, and future considerations.
