在“一带一路”逐步实施的背景下,我国和越南在农产品贸易市场的开拓潜力愈发增大,农产品贸易也越来越深入和密切。中越深化农产品经贸合作、共建“一带一路”具有互利性、必要性、紧迫性。为了弥补中越农产品贸易时效性及准确性的缺陷... 在“一带一路”逐步实施的背景下,我国和越南在农产品贸易市场的开拓潜力愈发增大,农产品贸易也越来越深入和密切。中越深化农产品经贸合作、共建“一带一路”具有互利性、必要性、紧迫性。为了弥补中越农产品贸易时效性及准确性的缺陷,本文将从中越双方农产品贸易现实情况出发,使用贸易指数来分析中越双边农产品贸易规模大小及历史发展趋势。通过中国与越南农产品贸易互竞性、互补性和结合度指数,对我国与越南双边农产品贸易及分类农产品的贸易潜力进行分析。 展开更多

当代社群主义政治哲学的主将、美国著名的思想家阿拉斯代尔.麦金太尔在对当代新自由主义的规则正义理论否定性批判的基础上提出了自己的德性正义理论,开启了从道德视角论证正义理论的先河。德性正义理论主张:社会正义应是一种基于实践... 当代社群主义政治哲学的主将、美国著名的思想家阿拉斯代尔.麦金太尔在对当代新自由主义的规则正义理论否定性批判的基础上提出了自己的德性正义理论,开启了从道德视角论证正义理论的先河。德性正义理论主张:社会正义应是一种基于实践之上的德性或美德,这种德性正义是具体的、发展的和多元互竞的,而且主张应得是正义分配的终极原则。 展开更多

本文选取2001—2013年贸易数据,采用显性比较优势指数、相对显性优势指数和贸易互补指数和贸易强度指数,分别对中国与土耳其农产品贸易的比较优势、互竞性、互补性及增长潜力进行定量分析。研究结果表明:中国与土耳其各自的优势农产品... 本文选取2001—2013年贸易数据,采用显性比较优势指数、相对显性优势指数和贸易互补指数和贸易强度指数,分别对中国与土耳其农产品贸易的比较优势、互竞性、互补性及增长潜力进行定量分析。研究结果表明:中国与土耳其各自的优势农产品类别不一,两国在农产品贸易上既存在互竞性又存在互补性;但双方农产品的贸易互补性未能得到充分发挥;具有互补性的农产品的贸易联系紧密程度低下,中土两国农产品贸易仍然具有极大的增长潜力。双方急需加强在农产品贸易上的合作,促进进出口农产品结构合理化,带动中土农产品贸易规模扩大,尽早实现贸易平衡,推动中国与土耳其农产品贸易健康、持续发展。 展开更多

Plant competition has been recognized as one of the most important factors influencing the soructure and function of lake ecosystems. Competition from plants of dissimilar growth form may have profound effects on shallow lakes'. An experiment was conducted to investigate the effects of competitive interactions of submersed plants with dis- similar growth forms on the biomass allocations. Hydrilla verticitlata and Vallisneria natans were selected and were planted in a single-species monoculture and a mixed-species pattern, Results showed that the growth of E natans was' significantly affected by the tt, verticillata and caused a sharp reduction of biomass, but the root:shoot ratio of E ha- tans was not affected significantly and there was a minimal increase in mixture: while for H. verticillata, the biomass and the root:shoot ratio were not significantly changed by the competitive interactions ore natans, there was minimal increase of biomass and minimal decrease of the root:shoot ratio. These results may indicate that theplant which can develop a dense mat or canopy at the water surface would be a stronger competitor relative to the plant that depends more on light availability near the sediment. 展开更多

Such ingame entities are controlled by artificial intelligence that is sought to match the user's skill. Defining and understanding the given human-computer-interaction videogame genres can be differentiated in either competitive matches or coherent plays. While artificial intelligence answers in responsive patterns only, natural intelligence holds creative qualities. A match is a game that creates suspense over the question of who is going to prevail. It can thus only be a game that features competing human players, since a computerized opponent is unaware of the game's significance. The nature of the match lies within the interactive trial. In a play, however, there is no battle but only cooperation. The aesthetics of such a play unfold to the audience, its purpose is showing rather than experiencing and/or competitively interacting. Artificial intelligence is then a surrogate that is often used in videogames to create an illusion of competition or battle. Its actual purpose is not to feature a worthy opponent, but to be a programmatic loser. In narrative and linear videogames, such as AI takes the role of a supporting actor whose function in the plot is, to signalize the player's dominance. 展开更多

Interactions between two plant species can be infuenced by the presence of other plant species and such an effect may change as the diversity of the other species increases.To test these hypotheses,we frst constructed aquatic communities consisting of 1,2 and 4 emergent plant species and then grew ramets of Lemna minor only,ramets of Spirodela polyrhiza only or ramets of both L.minor and S.polyrhiza within these aquatic communities.We also included controls with ramets of L.minor,S.polyrhiza or both but without any emergent plants.Biomass and number of ramets of L.minor and S.polyrhiza were signifcantly smaller with than without the emergent plants,but they did not differ among the three richness levels.The presence of S.polyrhiza did not signifcantly affect the growth of L.minor,and such an effect was not dependent on the richness of the emergent plant species.Without the emergent plant species,the presence of L.minor markedly reduced biomass(-92%)and number of ramets(-88%)of S.polyrhiza.However,such a competitive effect of L.minor on S.polyrhiza became much weaker in the presence of one emergent plant species(-46%biomass and-39%number of ramets)and completely disappeared in the presence of two or four emergent plant species.Therefore,both the presence and richness of emergent plant species can alter competitive interactions between the two duckweed species.These fndings highlight the importance of species diversity in regulating plant-plant interactions. 展开更多
