In the past 50 years, a marked reduction has occurred in European and North American children's freedom of movement and outdoor play. Using a structural equation model, the present study investigates the interaction between personal, environmental, and psychosocial factors that affect children's independent mobility. The study involved 313 mothers of 8–10-year-old Italian children. The results supported the hypothesized model: the age of the child, the maternal perception of social danger, and positive potentiality of outdoor autonomy were the most influential variables on children's independent mobility, measured as an index. Further, the maternal perceptions mediated the influence of the other demographic, psychosocial, and environmental variables on independent mobility.  相似文献

发掘图像的文学史意义成为文学史研究取得突破的重要途径。图像的文学史意义主要表现为两方面:一、文献学意义上的视觉史料,图像作为印证相关社会历史知识的可视证据;二、阐释学意义上的视觉文本,图像作为文学的视觉化形态,成为文学史的基本构成之一。文学图像成为重新理解和阐释文学史的重要视角。图文互释是图像的文学史意义更为本质的体现。  相似文献

This study used an instrument to examine undergraduate students' preferred and actual learning environment perceptions in an introductory earth science course. The results show that science students expect to learn in a learning environment combining teacher-centred and student-centred approaches. However, an expectation incongruence was found in that the instruction did not match with the students' preference on student-centred learning environment in this course. The results carry important implications in the interpretation of students' classroom behaviours and their school culture background. It is noted that students and teachers perceive differently whether the classroom environment is constructed as being student-centred.  相似文献

神话意象的意蕴衍生可分为整体性意蕴衍生和个体性意蕴衍生两种基本类型。整体性意蕴衍生是神话意象与特定历史情境相结合的结果,体现出社会群体的认知、情趣和理想;个体性意蕴衍生既有单个神话意象意蕴发生衍生的情况,也有作为个体的哲学家、文学家和艺术家等对神话意象进行再创作进而形成的意蕴衍生情况。这两种类型相互交织、共同发展,构成了神话意象意蕴衍生的基本模式。  相似文献

论文对中国海外利益及其政治风险这两个概念进行了界定;把海外利益按照类别分为海外安全利益、海外经济利益和海外形象利益;从国家对外资源投资、企业海外并购以及华商海外经营三方面,分析了中国海外利益面临的主要政治风险,认为在新一轮国际格局变动时期,中国海外利益面临的政治风险在加大。鉴于华侨华人是保护中国海外利益的重要依托力量,中国应拓展侨务公共外交的特殊渠道,并提出了未来侨务公共外交的努力方向。  相似文献

This case study surveyed students in geography courses at the University of Idaho, investigating perceptions of geography's role in their daily lives, relevance to careers or academics, and parts of their geographic skill. Primarily, white, younger than 20, gender-balanced students in Introduction to Physical Geography and Human Geography courses comprised the study sample. A sample of 265 students formed the pre-course survey and 82 students formed the post-course survey. Pre-course, men held a more positive sense of geographic skill, while women viewed more positively geography's relevance to careers and academics. Post-course, women's agreement concerning geography's role significantly increased, outpacing men's agreement.  相似文献

In this paper we report the results of an experiment with automated landform delineation and classification from digital elevation models (DEMs) using object-based image analysis (OBIA). Archaeologists rely on accurate and detailed geomorphological maps to predict and interpret the location of archaeological sites. However, they have been using high-resolution DEMs primarily for visual interpretation and expert-judgement classification of landform. OBIA can perform these classifications much faster and in a more objective fashion. The method was tested on a study area in the south east of the Netherlands. It is concluded that OBIA is a suitable technique for quick and objective delineation of landform, but needs an improved conceptual framework adapted to the local situation and archaeological questions to better identify and interpret the derived landform objects.  相似文献

William Alexander was the official draughtsman of the Macartney Embassy. His pictures of China covered a wide range of themes. Each theme represented a certain purpose. Landscapes, architectural drawings, and portraits constituted the majority of the drawings, which reveal the Embassy’s enthusiasm for obtaining visual knowledge of a variety of aspects in the society of China. The drawings of still life, costume, native species, and religious ceremony occupied the remainder, and provided the audience with a more intricate impression of China. In comparison with other European and some earlier generation artists’ works, Alexander’s pictures convey a peculiar British idea of China at the time, and hint at the potential crisis between the two countries.  相似文献

In this study, we assess whether students and their faculty mentors in a Research Experience for Undergraduates program have similar perceptions about the relative importance of different outcomes of their study abroad experience. Results of a Q-analysis reveal a significant difference of opinion between the students and the faculty mentors. It is argued that the faculty mentors need to spend more time in the field with their students and recognize that undergraduate research provides students with skills and a confidence to conduct research in the future, rather than personal and professional development, and the ability to think like a scientist.  相似文献

This paper proposes the need for heritage strategies and policies to engage with the psychological literature on risk perception because current heritage processes exclude many groups of people due to the psychological processes that are favoured in current procedures. Risk perception research has affected mitigation strategies in the realms of natural disaster planning (for example, earthquake preparedness) and, more recently, climate change mitigation. The paper outlines relevant psychological research and highlights areas that have the potential to inform heritage loss mitigation.  相似文献
