荣获1925年诺贝尔文学奖的萧伯纳声名卓著,“萧伯纳式”戏剧的独特魅力激发了众多西方学者的探索热情,对于他的研究早巳成为英美等国家的一门显学。自五四新文化运动时期起,萧伯纳其人其作进入了国人的接受视野。在近百年的时间中,萧伯纳的名字在中国耳熟能详,但迄今为止,他的著作被翻译成中文的依然有限,对他的研究也远未达到系统深入的程度。全面梳理萧伯纳在国内的接受历程,透析其在特定社会历史语境中的流播及演变,有助于推动国内萧伯纳研究的深化。 相似文献

Global coastal oceans as a whole represent an important carbon sink but, due to high spatial–temporal variability, a mechanistic conceptualization of the coastal carbon cycle is still under development, hindering the modelling and inclusion of coastal carbon in Earth System Models. Although temperature is considered an important control of sea surface pCO2, we show that the latitudinal distribution of global coastal surface pCO2 does not match that of temperature, and its inter-seasonal changes are substantially regulated by non-thermal factors such as water mass mixing and net primary production. These processes operate in both ocean-dominated and river-dominated margins, with carbon and nutrients sourced from the open ocean and land, respectively. These can be conceptualized by a semi-analytical framework that assesses the consumption of dissolved inorganic carbon relative to nutrients, to determine how a coastal system is a CO2 source or sink. The framework also finds utility in accounting for additional nutrients in organic forms and testing hypotheses such as using Redfield stoichiometry, and is therefore an essential step toward comprehensively understanding and modelling the role of the coastal ocean in the global carbon cycle. 相似文献

Endothelialization is of great significance for vascular remodeling, as well as for the success of implanted vascular grafts/stents in cardiovascular disease treatment. However, desirable endothelialization on synthetic biomaterials remains greatly challenging owing to extreme difficulty in offering dynamic guidance on endothelial cell (EC) functions resembling the native extracellular matrix-mediated effects. Here, we demonstrate a bilayer platform with near-infrared-triggered transformable topographies, which can alter the geometries and functions of human ECs by tunable topographical cues in a remote-controlled manner, yet cause no damage to the cell viability. The migration and the adhesion/spreading of human ECs are respectively promoted by the temporary anisotropic and permanent isotropic topographies of the platform in turn, which appropriately meet the requirements of stage-specific EC manipulation for endothelialization. In addition to the potential of promoting the development of a new generation of vascular grafts/stents enabling rapid endothelialization, this stage-specific cell-manipulation platform also holds promise in various biomedical fields, since the needs for stepwise control over different cell functions are common in wound healing and various tissue-regeneration processes. 相似文献

Research and theory concerning the value of play for children's development as well as current factors reducing the amount of play time that children experience are discussed. To ascertain play opportunities occurring in the schools, teachers' attitudes toward play, and provision of play for children in grades 1–6 were surveyed. The amount of recess time provided ranged from 0 to 65 min., with a mean of almost 19 min. Findings indicated that teachers from rural areas provided more play time than teachers from suburban areas, who in turn provided more play time than teachers in urban areas. Further, the amount of play time provided was influenced by the teachers' attitudes. That is, teachers who indicated generally positive attitudes toward play tended to allot more time for play in school. However, teachers from upper grade levels, who were more likely to perceive greater pressure to provide highly structured academic instructional programs, tended to de-emphasize the role and value of play and in turn allotted less time for play in school. The results of the present investigation demonstrate that children who are given less recess time are also likely to have teachers who report less positive attitudes toward play. It is recommended that school psychologists be aware of the adverse impact that restricted play opportunities may have on children's development. © 1996 John Wiley & Sons, Inc. 相似文献
