试分析影片《可可西里》中的空间叙事     

潘万里 《宁波广播电视大学学报》2013,(3):116-119

《可可西里》作为一部优秀的藏族题材影片,制作者对于对电影镜头空间及镜头间空间的细腻处理,构建了复杂的空间关系.这些关系转化为影片中人与人、人与物的关系后发挥了重要的叙事功能,且很大程度上丰富和深化了影片主题：当人类自身的生存空间都面临威胁时,自然生态空间的平衡如何得到维护？暴力侵犯式的介入或是以暴制暴式的保护是否合适？ “万物平等”还是“适者生存”？人类在强大的自然空间威胁时又当如何作为？  相似文献

Understanding the topic evolution of scientific literatures like an evolving city: Using Google Word2Vec model and spatial autocorrelation analysis

Topic evolution has been described by many approaches from a macro level to a detail level, by extracting topic dynamics from text in literature and other media types. However, why the evolution happens is less studied. In this paper, we focus on whether and how the keyword semantics can invoke or affect the topic evolution. We assume that the semantic relatedness among the keywords can affect topic popularity during literature surveying and citing process, thus invoking evolution. However, the assumption is needed to be confirmed in an approach that fully considers the semantic interactions among topics. Traditional topic evolution analyses in scientometric domains cannot provide such support because of using limited semantic meanings. To address this problem, we apply the Google Word2Vec, a deep learning language model, to enhance the keywords with more complete semantic information. We further develop the semantic space as an urban geographic space. We analyze the topic evolution geographically using the measures of spatial autocorrelation, as if keywords are the changing lands in an evolving city. The keyword citations (keyword citation counts one when the paper containing this keyword obtains a citation) are used as an indicator of keyword popularity. Using the bibliographical datasets of the geographical natural hazard field, experimental results demonstrate that in some local areas, the popularity of keywords is affecting that of the surrounding keywords. However, there are no significant impacts on the evolution of all keywords. The spatial autocorrelation analysis identifies the interaction patterns (including High-High leading, High-Low suppressing) among the keywords in local areas. This approach can be regarded as an analyzing framework borrowed from geospatial modeling. Moreover, the prediction results in local areas are demonstrated to be more accurate if considering the spatial autocorrelations.  相似文献   

河西走廊旅游空间开发模式初探     

柳红波 《河西学院学报》2008,24(4)

受自然地理条件和绿洲经济的影响,河西走廊城镇间距离过长,景区、景点分布分散,造成了河西走廊旅游经济发展缓慢,区内旅游经济发展不平衡的现状。针对这种状况,应选择"据点式"和"点轴式"相结合的空间开发模式对河西走廊进行旅游开发。构建以武威、张掖、酒泉(嘉峪关)、敦煌为"旅游中心地",以古丝绸之路(陇海、兰新铁路线)为"轴线"的空间开发模式。  相似文献

Research in non-equalization machining method for spatial cam   总被引：1，自引：0，他引：1  

Jun-hua Chen  Yi-jie Wu 《浙江大学学报(A卷英文版)》2008,9(9):1258-1263

Many kinds of devices with cam have been widely used in various mechanical equipments. However, non-equalization machining for spatial cam trough remains to be a difficult problem. This paper focuses on the analysis of running conditions and machining processes of spatial cam with oscillating follower. We point out the common errors in the biased distance cutting. By analyzing the motion of oscillating follower of spatial cam, we present a new 3D curve expansion model of spatial cam trough-outline. Based on this model, we have proposed a machining method for trochoidal milling with non-equalization diameter cutter. This new method has led to a creative and effective way for non-equalization diameter machining for spatial cam with oscillating follower.  相似文献   

Aged-based differences in spatial language skills from 6 to 10 years: Relations with spatial and mathematics skills     

《Learning and Instruction》2021

Spatial language is the language of spatial concepts and spatial relationships. Prior research has demonstrated an association between spatial language and spatial thinking in pre-school children. However, there is limited evidence exploring age-based differences in spatial language in older childhood. This cross-sectional study has three main aims. First, we present a novel spatial language measure and show differences in spatial language performance across age groups from 6 to 10 years (N = 155). Second, having demonstrated that our measure is sensitive to age-based progression, we use regression analyses to determine relations between spatial language and performance on a range of spatial tasks (r²:1.2%–9.0%). Third, we investigate the relations between spatial language and different mathematics skills (r²:0.2%–15.4%) and propose mechanisms that may explain these associations. We discuss how these findings lay a foundation for future spatial language interventions as a novel tool which may lead to educational improvements in mathematics.  相似文献   

Developmental trajectories of children's spatial skills: Influencing variables and associations with later mathematical thinking     

《Learning and Instruction》2021

Few studies have examined the long-term relations between children's early spatial skills and their later mathematical abilities. In the current study, we investigated children's developmental trajectories of spatial skills across four waves from age 3–7 years and their association with children's later mathematical understanding. We assessed children's development in a large, heterogeneous sample of children (N = 586) from diverse cultural backgrounds and mostly low-income homes. Spatial and mathematical skills were measured using standardized assessments. Children's starting points and rate of growth in spatial skills were investigated using latent growth curve models. We explored the influence of various covariates on spatial skill development and found that socioeconomic status, language skills, and sex, but not migration background predicted children's spatial development. Furthermore, our findings showed that children's initial spatial skills––but not their rate of growth––predicted later mathematical understanding, indicating that early spatial reasoning may play a crucial role for learning mathematics.  相似文献
