In 2013, The Better Image (TBI) was contacted to examine A Play of Selves, a unique work created by artist Cindy Sherman during her graduate studies in 1975. The work is composed of 244 paper doll-like photographs of Sherman that are presented within 72 frames. During initial condition checks, it was noted that a number of individual elements had begun to show signs of chemical staining. Over the course of 2013/2014, a collaborative response was developed with the help of the artist, the artist's printer, the representing gallery, TBI staff and the owner. The main goal was to address the physical and chemical issues present and preserve this work for future exhibition and study. Determining an effective decision- making model based on a hierarchy of values was crucial before undertaking any conservation treatment, as there were several invested parties, each with a different perspective. The focus of this paper is the interplay of our responsibilities as conservators with the concerns of the artist, her gallery, her printer, and the owner to balance aesthetic vs. physical integrity of the artwork, reversibility of treatments, importance of record keeping while developing a balanced response within a world of rapidly disappearing traditional photographic papers.  相似文献

This paper offers the experiences and insights of two faculty members, located in two separate disciplines, as they engaged in collaborative research. While knowledge created by stepping out and reaching across disciplines reflects the reality of an increasingly complex world, their experiences highlight both the benefits of a supportive collaborative partnership as well as the risks and discomfort experienced without tangible discipline support, when researchers stray too far from their home discipline. While transparency and attention to process is critical to all researchers engaged in collaborative partnership, its necessity is heightened when venturing beyond the territory of familiar disciplines.  相似文献

袁毓林前些年对有价名词以及名词性偏正词组中谓词隐含等问题所进行的研究,确实反映了本学科的新进展及前沿性成果。然而这种研究毕竟属于纵深探讨性质。事实上,中心语只有具备[ 转让]语义特征时,提取宾语且隐去谓词的“的”字结构才能称代它。该词组中谓词隐合并非普遍性的,典型领有关系的才可能有这种潜在的句法述谓性质。关于“的”字结构,我们赞同朱德熙先生“自指”“转指”语义类型的区分,并给予了进一步的证明。  相似文献

INTRODUCTION A common method for extracting depth in-formation from intensity images is based on theprinciples of stereovision. In this method, a pair ofimages is obtained using two cameras displacedfrom each other by a known distance. After deter-mining the stereo correspondence, the distance ofvarious points is computed using triangulation(Jeon et al., 2001). Stereo correspondence is theproblem of finding corresponding points in two ormore images of the same scene, usually assumin…  相似文献

BackgroundCollaborative small-group discussions have the potential to promote reading comprehension, critical thinking, and argumentation. However, few studies have gone beyond cognitive processes to understand the social characteristics of dialogue and their potential contributions to students’ cognitive processing in turn-by-turn dialogic exchanges.AimsThis study closely examined dialogues between speakers and addressees regarding their levels of cognitive processing (i.e., cognitive dialogue patterns) and social processes reflecting social cohesion (i.e., social dialogue patterns). The aims were to understand, first, the relations between students' cognitive dialogue patterns and their social dialogue patterns, and second, the relations between students' cognitive dialogue patterns and peers’ social dialogue patterns.SampleThis study included 4070 speaking turns generated by 120 fifth-graders in 60 small-group discussions.MethodsStudents participated in small-group discussions, called Collaborative Social Reasoning. Dialogue between pairs of group members formed social networks, based on which Exponential Random Graph Models (ERGMs) were specified.ResultsFindings showed that speakers' social dialogue patterns were associated with their cognitive dialogue patterns. However, receiving social dialogue patterns from peers did not always predict students’ advanced types of cognitive dialogue patterns.ConclusionsThis study demonstrated that cognitive and social aspects of small-group discussions are intricately linked, and that encouraging social cohesion does not guarantee that students will engage in collaborative and critical discussions.  相似文献

欧美许多国家非常重视外语教育,对外语能力标准的研究已有六十多年的历史,制定的语言能力标准也日趋完善;日本也发表了《JF日语教育标准2010》。多年来,我国日语教学大纲一直是日语教育的评价标准和教学目标,为日语教材的编写、日语教学的规范化及日语能力评估等方面提供了一定的指导依据。但我国对于日语教育却一直没有一个更为详细的标准出台。文章介绍了国外的外语能力标准,并分析其最新理念,以期为我国的日语能力标准建设提供参考。  相似文献
