对学生的实际拍摄过程和作品分析发现,学生摄影作品中,艺术的体现的确存在相当程度的不足;在实际拍摄过程中,表现出的对单反相机驾驭操控能力的欠缺也普遍存在。目前摄影教学中表现出来的问题,不只是技术或者艺术哪一个单方层面的偏颇,过于推崇“技术流”或“艺术流”都是片面的,技术与艺术并重的“两条腿走路”才是应该提倡的教学和学习方法。  相似文献

White and Bruning (2005) distinguished two sets of writing beliefs: transactional and transmissional beliefs. In this paper we analyse their beliefs scale and suggest two hypotheses about how such beliefs relate to writing performance. The single-process hypothesis treats the beliefs as different amounts of engagement, whereas the dual-process hypothesis claims that the beliefs represent different types of engagement. We then describe the results of an experiment with 84 university students as participants that assessed the relationship between writing beliefs, different forms of pre-planning and different aspects of writing performance. Our results support the dual-process hypothesis, and suggest that transactional beliefs are about the preference for a top-down strategy or a bottom-up strategy, while transmissional beliefs are about the content that is written about. These beliefs interact in their effects on text quality, the amount and type of revision carried out, and the extent to which writers develop their understanding. They also moderate the effectiveness of outlining as a strategy.  相似文献

This paper assesses how use of smartphones relates to exposure to heterogeneity, political efficacy, and political engagement and suggests a new mediation model that can be applied to mobile communication. Drawing on online survey data collected during the 2012 presidential election in South Korea, this study finds that exposure to heterogeneity and political efficacy jointly mediate the impact of informational uses of smartphones on political participation. The current study also shows that informational uses of smartphones are significantly related to encounters with heterogeneity, political efficacy, and participatory behaviors. Additionally, recreational uses of smartphones were found to have a positive association with exposure to heterogeneity. However, relational uses of smartphones were not associated with democratic outcomes. The findings suggest that smartphones, by increasing the possibility of encountering diversity and subsequently enhancing political efficacy, create an additional pathway to citizen engagement in democratic processes.  相似文献

This paper discusses the relationship between the language use patterns of multilinguals and their media preferences and exposure. Specifically, it examines the language behavior of multilinguals in Belize where television is available in both English and Spanish. A survey of Belizean high school students conducted in both languages, asked about their sociolinguistic patterns and media preferences and exposure. The results indicate that the frequency of a particular language's use correlates with preferences for and exposure to television in that language. This relationship is more pronounced when specific cultural programming is considered.  相似文献

This article discusses the risks and possibilities of communicating and educating the child's emotional self in a formal classroom environment. Through designing and implementing an expressive arts curricular intervention in a Scottish primary school classroom, my research produces an example of how therapeutic notions focused upon health and wellbeing can be integrated into contemporary education. Four case studies are provided to exemplify how individual children made particular sense of emotional expression through their own lens of interactive communication with parental figures. This article argues that educators' active and ongoing awareness of boundaries, disclosure and exposure will determine the ethical nature of a child's educational experience with emotional expression.  相似文献

Automatic text classification (TC) is essential for information sharing and management. Its ideal goals are to achieve high-quality TC: (1) accepting almost all documents that should be accepted (i.e., high recall) and (2) rejecting almost all documents that should be rejected (i.e., high precision). Unfortunately, the ideal goals are rarely achieved, making automatic TC not suitable for those applications in which a classifier’s erroneous decision may incur high cost and/or serious problems. One way to pursue the ideal is to consult users to confirm the classifier’s decisions so that potential errors may be corrected. However, its main challenge lies on the control of the number of confirmations, which may incur heavy cognitive load on the users. We thus develop an intelligent and classifier-independent confirmation strategy ICCOM. Empirical evaluation shows that ICCOM may help various kinds of classifiers to achieve very high precision and recall by conducting fewer confirmations. The contributions are significant to the archiving and recommendation of critical information, since identification of possible TC errors (those that require confirmation) is the key to process information more properly.  相似文献

We investigate how, and to what extent, morphological complexity of the language influences text classification using support vector machines (SVM). The Croatian–English parallel corpus provides the basis for direct comparison of two languages of radically different morphological complexity. We quantified, compared, and statistically tested the effects of morphological normalisation on SVM classifier performance based on a series of parallel experiments on both languages, carried over a large scale of different feature subset sizes obtained by different feature selection methods, and applying different levels of morphological normalisation. We also quantified the trade-off between feature space size and performance for different levels of morphological normalisation, and compared the results for both languages. Our experiments have shown that the improvements in SVM classifier performance is statistically significant; they are greater for small and medium number of features, especially for Croatian, whereas for large number of features the improvements are rather small and may be negligible in practice for both languages.  相似文献

无论是在《易经》还是在《易传》中 ,“圣人”、“君子”的概念都频繁的出现。在《周易》的人格价值判断体系中 ,“圣人”、“君子”是理想人格的代表 ,具有“仁”、“义”、“谦”、“慎”等等美德 ,要达到这样的人格境界则在对自然、社会和人的关系上都应有所努力。《周易》中的理想人格还具有一定的现代意义  相似文献
