视觉性与图画性(I)

文化艺术研究 2013年第3期6卷 134-144页

作者： whitney davis 彭发胜加州大学伯克利分校合肥工业大学外国语学院合肥230009

视觉性是视觉体验的象征形式。视觉性与图画性尽管总是可以相互转化,但无论在任何一点上都不完全等同。事实上,在它们进行意义垒叠的每一时刻,视觉性和图画性必须相互分离。图画不能完全表达视觉性本质的"象征价值",正如视觉性不能完全... 详细信息

视觉性是视觉体验的象征形式。视觉性与图画性尽管总是可以相互转化,但无论在任何一点上都不完全等同。事实上,在它们进行意义垒叠的每一时刻,视觉性和图画性必须相互分离。图画不能完全表达视觉性本质的"象征价值",正如视觉性不能完全容纳图画本质的"形式价值"。这种根本的分离造成各种分裂状况,由此激发视觉想象和图画构造,形成了从形式到象征,从图像到"话语",从感知到理智,或者其反向循环的真正机制。

视觉与视觉文化中的垒叠

巴桑戴尔考虑的是视觉实践如何成为一种再现的模式(从观看世界到图绘世界),瓦托夫斯基考虑的则是一种再现的模式如何成为一种视觉概观(从图绘世界到观看世界)。但是这两种方式原则上是一个循环不已的完整回路——从图画到世界,到图画,... 详细信息

巴桑戴尔考虑的是视觉实践如何成为一种再现的模式(从观看世界到图绘世界),瓦托夫斯基考虑的则是一种再现的模式如何成为一种视觉概观(从图绘世界到观看世界)。但是这两种方式原则上是一个循环不已的完整回路——从图画到世界,到图画,再到世界,一直持续。瓦托夫斯基称之为一个"螺旋线"。情况确实如此,尽管这不是(至少不只是)一个经典图绘风格(以及观看方式)在人类视觉史中前后垒叠的螺旋线。存在于其中的其实是图画的螺旋线,也就是说,任何图画必须以其风格特征才能部分被我们认识。

"古典"时期浮雕作品的"同位构图"模式,其特征是各种人物形象和元素之间的孤立,相互构成对方的同为元素或是附属单元,并不构成有机的整体。阿玛纳时期的艺术家对于创作构图的作用有着充分认识和自觉,首次综合运用风格、准则、哲学和传统来生产艺术作品,使得作品的整体布局取代了同位创作构图中孤立的形式和意义特征的聚合,是这一时期艺术创作的重要创新。

American Journal of Climate Change 2024年第2期13卷 194-208页

作者： Yehuda davis Henry He Huang Sy Syms School of Business Yeshiva University New York USA

This review focuses on major contemporary empirical studies that examine both the physical and regulatory sides of climate risk. These studies explore how climate risk affects firms’ operating performance and leverage, stock and bond valuation, cost of capital, and managerial behavior. We also discuss how the effect of climate risk on real estate markets depends on individuals’ beliefs about climate change. Furthermore, we summarize papers on climate risk activism and how firms can employ financial devices and technology to mitigate their climate risk. Finally, we make some recommendations for further research areas.

Background Multiple cerebral venous sinus thrombosis(CVT)registries from various geographical regions indicate that female gender,the use of contraceptive pills,pregnancy and puerperium are important risk *** this study,we report the changes in the epidemiology of patients with CVT managed over the past 26 *** The CMC Vellore CVT registry is a prospectively maintained database at the Christian Medical College,Vellore since January *** software was used to analyse the data and assess the changes in the incidence,age and gender distribution over the previous 26 *** Among 1701 patients treated during the study period,908(53%)were women and 793(47%)were *** mean incidence of CVT was 49 per 100000 admissions before 2010,which increased to 96 per 100000 after *** gender had a higher odds of developing CVT OR–2.07(CI 1.68 to 2.55,p<0.001).This could be attributed to the declining incidence of postpartum CVT after 2010 compared with the decade before 2010(50%vs 20%).The mean age at presentation had increased from 24.5 to 33.2 years in the last *** There was a clear change in the gender pattern from being a condition with female preponderance,to one where equal or more men are being *** incidence of postpartum CVT cases could be the driving *** increase in the overall incidence of CVT cases was noted,probably due to a higher index of clinical suspicion and better diagnostic imaging modalities.
