基于流形学习与光谱解混的文物表面字迹增强——以云冈第38窟为例

文物表面的文字是了解历史的关键信息，对文物表面文字信息的探索成为文物保护的重要环节。结合流形学习与光谱解混，提出一种新的文物表面字迹增强方法。首先，利用基于流形学习的等距映射方法对预处理后的高光谱图像进行非线性降维，得到信息量最大的灰度图像；其次，分析文字与背景的光谱特征，通过多层非负矩阵分解方法得到字迹丰度图；然后，将二者进行加权平均得到字迹增强图像，再与合成真彩色影像进行HSV融合，得到字迹融合影像；最后，为更好地辨认文字，在字迹增强图像上裁剪文字并做形态学变换，得到字迹提取图。以云冈石窟第38窟的一景褪色文字高光谱图像为例进行了验证，结果表明，该方法能够有效地增强出文物表面的褪色文字，且较其他增强方法效果更好。

文化创意在博物馆中的运用

当今时代,随着我国经济的快速发展,生活水平不断提高,人们已不再满足于物质生活,提高文化生活需求的呼声已越来越高。作为文化产业的重要部门,博物馆已逐渐强调其开放性与多样性,增加观众的参与和互动。将其与文化创意相融合已成为文化部门当下最主要的任务和挑战,从而使得博物馆对我国的发展起到更加多元化的社会作用。     

国际博物馆理论研究的分化与整合——博物馆研究的两条思想路线札记

博物馆发展中的分化与整合不是孤立的,它是博物馆在适应社会发展大环境中产生的分歧,并且形成了两条各有侧重的思想路线:一条是以博物馆功能为基础的专业化路线,另一条是以博物馆职能为基础的社会化路线。当前,这两条思想路线正在新整合理论的整合下进行新的探索和实践。     

Insights Regarding Transdisciplinarity and Knowledge Transfer Gained from Two Case Studies on Integrated Water Resources Management in Ukraine and Mongolia

Abstract

Transdisciplinary environmental research (TD research) seeks to solve problems arising at the point of interaction between ecological systems, the economy, and society. It seeks to enhance problem-solving capacity through interdisciplinarity and knowledge transfer between scientific and non-scientific actors. The article assesses how far the prerequisites for knowledge transfer are met in transdisciplinary projects on integrated water resources management (IWRM), particularly in post-socialist transition countries. It examines two relevant case studies, in Ukraine and Mongolia, which share a similar institutional and cultural background, and use some of the same methods closely related to knowledge transfer. It is shown that, in each case, knowledge transfer was achieved more or less effectively in both directions — from science to society and vice versa, despite the additional obstacles posed by a common post-socialist legacy. The paper concludes with a number of recommendations for designing and implementing similar TD research projects in the field of IWRM.     

Attending to grape vines: perceptual practices,planty agencies and multiple temporalities in Australian viticulture

This article considers the agency of crop plants within sociocultural processes by examining how grape vines influence seasonal labour patterns in Australian viticulture and wine production. Drawing on ethnographic research within a large Australian wine company, I examine how vineyard managers and winemakers coordinate the timing of the grape harvest with the ripening of grapes. I argue that by making the harvest's approach perceptible to humans, chemical and sensory tests of grape ripeness precipitate seasonal changes in viticultural work—rendering grape vines active participants in patterning social time. Practices of attention to ripening grapes thus render the social agency of grape vines perceptible. I analyse these time-reckoning practices as a ‘learning to be affected’, in which human viticulturists actively strive through multiple sensory practices to become attuned to plants' activities. However, attending to the multiple practices used to reckon the ‘right’ time to harvest grapes also emphasises that these ways of enacting the times and agencies of crop plants may interfere or conflict with one another. Highlighting the emotional stresses and tensions between viticultural workers that this may generate, I suggest that agricultural time is both more conflicted and more suffused with power relations than theoretical accounts have typically indicated.     

实现保护性再利用的旧址博物馆

旧址博物馆是指利用特殊的空间来展示社会发展、事件发生、人物活动历史瞬间的博物馆,其中历史建筑旧址博物馆、名人故居旧址博物馆、工业遗产旧址博物馆等均是重要的表现形式。充分挖掘这些旧址博物馆的文化内涵,展示建筑旧址的文化面貌及特色,探索保护旧址博物馆真实遗存、历史环境的有效方式,从而实现对旧址博物馆文化遗产的合理再利用等课题,在当前具有重要的意义。     

从信息传播到注意力传播——当代博物馆展示理论的变迁与思考

博物馆作为一个非正式教育机构,通过展示向观众传播文化知识,进行信息灌输是其工作职责.在传统的信患传播模式下,博物馆优先考虑的是传播的内容及其数量的多寡.然而,随着信息社会的到来,注意力成为一种稀缺资源.博物馆要在日益激烈的注意力竞争中实现其社会效益和经济效益,就必须从注意力传播模式中寻找突破.
