考尔雅典女神，雅典卫城682——尊希腊古典晚期雕塑的重建工作

在15世纪的意大利,人们发现了大量的古代雕塑遗存,基本上都是大理石雕塑残片。出于对大理石的迷恋、对雕刻工艺的欣赏、对人体雕塑生动表现的着迷,当时的贵族热衷于收集这些残片并试图拼对与重建这些残破的雕塑。但是几乎没有发现任何颜色的残存,他们甚至不会去探究彩绘他们更赞赏大理石洁白无瑕的表面。19世纪早期,建筑学家们考察了西西里一些古代庙宇的彩绘残存,随后有关一些著名希腊神庙（如帕台农神庙）彩绘的重构工作在全欧洲引发了热烈的讨论。但是对于这些雕塑涂施彩绘的强烈质疑声一直持续到十九世纪八十年代,直到雅典卫城发掘工作的开展才证实了古代大理石雕塑彩绘的事实。出土时,很多破碎的雕塑残片上都残存有鲜亮的彩绘,但通常在出土几个小时后就由于干燥而剥落了,只有依稀的彩绘痕迹残存,以及工作人员的描述和水彩模画。今天,翻开现代有关古代雕塑的书籍,你会发现大量彩色照片,但总是显现白色大理石表面。有关雕塑的工艺、功能和历史发展的意义的讨论已经很多了,但是很难得到一个完整的古代雕塑彩绘的例子。不仅仅是雅典卫城的雕塑曾经涂饰彩绘,经过重建工作这一时期有大量彩绘的例子。本次工作即是采用古代颜料与模具,尽可能完整的重建了一尊古代雕塑。     

Labour Productivity and Energy Use in a Three‐Sector Model: An Application to Egypt

This article presents a model of a developing economy with three sectors — industry, agriculture and energy. Industry and energy are assumed to be demand‐constrained, but agriculture supply‐constrained. The model highlights: (a) structural transformation, through labour transfer from agriculture to industry; (b) inflation, driven by the interaction of demand and the supply constraint in agriculture; and (c) the link between energy use and labour productivity. Employing a Kaldor‐Verdoorn productivity rule in industry augmented with energy intensity — energy per unit of labour — as an argument, we emphasize that labour productivity growth is driven by energy intensity rather than energy productivity growth. As a consequence, emissions reduction without North–South technology transfer and financial assistance costs growth.     

Sustainability transformations in the balance: exploring Swedish initiatives challenging the corporate food regime

ABSTRACT

This paper explores to what extent organic initiatives that go beyond mainstream organic (so-called Organic 3.0) can challenge the corporate food regime and how they can push the food system towards sustainability transformations. We depart from the assumption that individual initiatives may differ in their potential to influence the corporate food regime and that this potential can be assessed by examining traits linked to reformist, progressive or radical food regime/food movement trends that they may possess. Rather than establishing a dichotomy between niche and food regime or categorizing Organic 3.0 initiatives within one of these trends, we explore the nuances in niche–regime relationships within the food system from a multi-level perspective, using the cases of two Organic 3.0 initiatives in Sweden. The results show that relations between these initiatives and the food regime share key characteristics, but also differ in important respects. While a reformist strategy facilitates niche growth, progressive and radical approaches are more likely to challenge the regime. The choice of approach in both cases involves trade-offs between growth and organic values. We conclude that one of the primary roles of Organic 3.0 initiatives may be to illustrate the viability of alternative models.
