This study investigated the role of working memory capacity as a factor for individual differences in the ability to compose a text with communicative efficiency based on audience awareness. We analyzed its differential effects on the dynamics of the writing processes, as well as on the content of the finished product. Twenty-five graduate students composed a procedural text explaining how to assemble a model turbine. They were free to consult a documentary source, featuring captioned pictures of turbine parts and assembly steps, at any time. Graphomotor and eye movements were recorded using ‘Eye and Pen’ software with an eye-tracker and digitizing tablet. Results showed that high WM capacity writers used a different strategy to explore the visual source, making longer writing pauses and producing more detailed procedures, and achieved the communicative goal more efficiently, by introducing more reader supports. In conclusion, we discuss the feasibility of audience awareness training. 相似文献

This paper takes as a case study an undergraduate field class from a UK university to rural Uganda. It describes and evaluates the use of video diaries as a tool for investigating the process of transformative learning in the context of education for sustainability. The applicability of threshold concept theory to this learning is investigated. Results show the video diary technique to be much more successful in capturing the development of student learning than written diaries. Despite some practical difficulties, rich data were generated. Analysis demonstrated that learning met three of the five criteria for threshold concepts: the learning was transformative, integrative and troublesome. Further research could test whether the learning in this case study met the threshold concept criterion of irreversibility. Further elaboration of the theoretical relationship between threshold concepts, transformative learning and education for sustainability is also needed. It is concluded that the video diary method is potentially transferable to other educational research contexts and may be particularly suitable for researching learning in threshold spaces. 相似文献

Collaborative research for sustainable learning: the case of developing innovation capabilities at Volvo Cars 总被引:1,自引:1,他引:0
Sofia Börjesson 《Action Learning: Research and Practice》2011,8(3):187-209
This paper aims to make a contribution to the stream of literature on action research by describing a longitudinal collaborative research project which evolved out of a long-term, participation partnership with Volvo Cars. The collaboration was aimed at developing innovation capabilities in the company and accumulating knowledge on how capabilities are developed. The paper provides insights into the design of collaborative research projects to enable mutual, sustainable learning. It draws on key notions in the literature on collaborative management research and action learning, highlighting the research design of the project at Volvo Cars and its relations to action learning. The paper describes how the research design opened the way to establishing a learning system at Volvo Cars while simultaneously generating new scientific knowledge within the area of innovation capabilities. The paper provides rich and detailed data on a collaborative research setting and highlights key aspects related to organizing and undertaking collaborative research. 相似文献

Depth maps are used for synthesis virtual view in free-viewpoint television (FTV) systems.When depth maps are derived using existing depth estimation methods,the depth distortions will cause undesirable artifacts in the synthesized views.To solve this problem,a 3D video quality model base depth maps (D-3DV) for virtual view synthesis and depth map coding in the FTV applications is proposed.First,the relationships between distortions in coded depth map and rendered view are derived.Then,a precisely 3DV quali... 相似文献

Mobile devices are increasingly powerful in multimedia transmitting and browsing. However, the small screen and different
aspect ratios of mobile devices lower visual quality while watching images or videos. Video retargeting is aim at fitting
an existing video into arbitrary size and aspect ratio. Previous content-aware retargeting methods are mostly high computational
cost, which limits their applications on the portable devices with low computation ability. In this paper, a new crop-and-scale
approach is presented to adapt video to better suit the target display. We automatically find the optimal parameters of cropping
window using the dynamic programming method, and then scale it to fit the target display. The cropping window can smoothly
shift during a shot to follow the movement of important objects. The retargeting results using our approach introduce no deformation
and jitter effects over the whole video. Experimental results show the success of our approach on adapting a variety of source
videos to small display sizes. 相似文献

This paper aims to gain insight into language production and academic language of 4- and 5-year-old students and their teachers in the course of a teacher intervention during kindergarten science education. The study is based on videotaped classroom observations, and specifically focuses on the academic language use of students (Nintervention = 18, Ncontrols = 26) and teachers (Nintervention = 5, Ncontrols = 5). The results suggest that this general teacher intervention yields interesting changes in language use and production. Patterns of change over time confirm the idiosyncratic and non-linear nature of these changes. Science lessons represent an appropriate context in which to acquaint students with academic language, which can be used as a basis to build upon more sophisticated language skills. 相似文献

现当代管理心理学领导行为与领导风格研究成果综述 总被引:1,自引:0,他引:1
通过对现代管理心理学中领导行为和领导风格研究成果的综述认为,西方管理心理学研究的结论在中国的推广存在严重的文化障碍,必须逐步本土化才能用来指导中国的党政管理和企业管理.20世纪的中国管理心理学关于领导行为和领导作风的研究,要么停留在西方管理心理学的介绍和跨文化验证方面,要么以西方文化为背景,批评中国企业家没有现代管理的心理素质,对中国古代儒家道家文化背景下形成的治国治家思想和以党的执政理论为框架的领导科学视而不见.西方的管理心理学和中国的领导科学就象两条铁轨,难以相交,主要的障碍在于话语的转换困难.心理学的本土化道路仍然很漫长. 相似文献

运用话语理论考察《太阳照在桑干河上》这一文本的"话语重构"现象,分别从写作初衷与创作过程中存在的悖论、版本变迁与意识形态的关系等方面分析其动态复杂的生产过程与意识形态氛围对于文学生产的隐蔽控制;进而探讨这一重构现象潜在的主观原因,即丁玲努力寻求自我与主流意识形态的身份认同;指出作家既是话语重构的主体,同时也是话语权利的重构对象. 相似文献

马克思认为,物质生产的发展同艺术生产的发展是不平衡的,这恰当地表述了物质生产与艺术生产的关系。希腊艺术的繁荣就证实了这一点。 相似文献
