高矮秆夏谷发育差异与其叶片POD酶谱变化的相关研究

研究了高矫秆夏谷不同发育时期叶片过氧化物酶同工酶（POD）酶谱变化及其地上部植体动态发育、干物质积累的变化。结果表明，谷子叶片POD酶谱的苗期和抽穗期酶带最丰富，高矮秆谷子在孕穗后的发育和灌浆过程中的干物质积累不同。酶谱中的B1、C1和C2带与其生长发育有关：A2、A3带与成株期株高有关。高矮秆材料的发育差异可在其叶片的POD上表达出来。     

由荷马史诗看希腊黑暗时代法律思想

荷马史诗这一彪炳千古的伟大史诗系列，是对半传说半史实的特洛伊战争的诗意叙述。史诗所反映的古希腊黑暗时代的法律思想，主要包括正义观和政体观两方面。荷马史诗中一切正义都是宙斯的意志，包括分配的正义和纠正的正义。其中分配的正义并非绝对平等，具有差异性的分配才能做到各得其所，而纠正的正义更多通过私人血亲复仇来体现，既符合复仇者自身的正义观，也体现了众神的正义观。荷马史诗中政体观主要通过描述其所处时代的政治演变来体现。从特洛伊到黑暗时代，史诗描述与历史事实的差异，体现了希腊民众对贵族政体的抵触。同时，史诗中政体观从一人统治的君主政体转变为少数人统治的贵族政体，这一变化为后世城邦时代多数人统治的民主政体的萌发和发展提供了土壤。     

玉米秸秆覆盖还田保护性耕作技术在东北地区的应用与发展路径

玉米秸秆覆盖还田保护性耕作技术的应用可减少黑土流失、恢复与提升黑土肥力，是东北地区深入推进黑土地保护工作的必然选择。本文在概述其技术作业模式和适用范围的基础上，从经济效益、土壤“体质”和“体型”3个方面阐述技术实施效果，分析技术推广应用的现状以及在推广过程中存在的农户应用不积极、补贴制度不合理、农艺农机脱节等困境。未来应采取措施提高农户的响应程度，科学界定作业补贴的对象与金额，大力支持配套农机的研发与创新。     

赵元任语言学思想研究述评

学界对赵元任语言学思想的研究可从宏观和微观两个角度来分析。从宏观研究来看，主要是基于赵元任的语言学思想对中西学术交流的贡献及对汉语语言学研究的总体影响这两个层面进行。从微观研究来看，主要是从赵元任在语音研究、语法研究、方言研究、语义学研究及普通语言学研究等方面的影响来讨论。现有的研究还需要进一步挖掘并重新审视其对当代汉语研究有启发价值的学术思想。     

中国佛教史上第一篇孟子学文献——《牟子理惑论》新探

东汉末年，浮屠、黄老为一家，神仙家异常活跃，而佛教初来乍到，社会影响小。牟子皈依佛法，又三教并重，十分重视孟子。《牟子理惑论》有实名涉孟语句6例、显性——匿名涉孟语句11例、孔孟并称4例，不仅文献学指标高，而且思想史分量重。孟子的许多思想及语句，尤其是距杨墨、辨夷夏、权时地等核心观点，得到《牟子理惑论》智慧的理论阐释与有效的实际运用，并藉以服务于佛教的自立及其中国化；牟子不仅以孟援佛，还多次并称孔孟，试图在大思想史上提升孟子的地位。《牟子理惑论》既是东汉重要的孟子学作品，也是交州孟子学的代表作，更是中国佛教史上第一篇孟子学文献，其在孟学史上的地位举足轻重。     

How perceived sensory dimensions of urban green spaces are associated with adults’ perceived restoration,stress, and mental health?

This study investigates associations between perceived sensory dimensions (PSDs) of urban green spaces (UGSs) and adults’ perceived restoration, stress, and mental health. Data were collected through surveys with 426 adults in 2019 in seven different UGSs in Aydın, Turkey. The PSDs of UGSs (nature, serene, space, rich in species, social, prospect, culture, and refuge) were evaluated and rated by two professional landscape architects. The perceived restorativeness (being away, fascination, coherence, and compatibility) was measured with the Perceived Restorativeness Scale, and health indicators (stress, mental health, mental health diagnosis, mental health treatment, general health, and quality of life) were measured with self-reported questions. Multivariate multiple regression analyses were conducted to examine associations controlling for confounding factors. Four of the eight PSDs were analyzed due to multicollinearity issues in the study. Regression analyses showed that ‘nature’ was positively associated with perceived restorativeness, stress, and mental health, while ‘refuge’ was only positively associated with perceived restorativeness. On the other hand, ‘serene’ was negatively associated with perceived restorativeness. Whereas ‘rich in species’ was found to be negatively associated with perceived restorativeness and positively associated with mental health diagnosis. In addition, findings showed that frequency of and duration of UGSs visit were negatively associated with perceived restorativeness. The findings suggest that providing characteristics of ‘nature’ and ‘refuge’ in UGSs may provide restorative effects and mental benefits to adults. However, unexpected results suggest that further research is needed before using these characteristics as a tool by landscape architects and city planners.
