“自媒体”时代“苏区”城市化进程的影像构建探析--以闽北武夷山大安、坑口等地为例

城市化进程中,城市的品牌形象对其发展无疑起到积极的促进作用。当下我们生活在人人都有相机、人人都会拍照、处处都有屏幕、全民都是媒体的“全媒体”时代,就如何发挥数码影像在大众传媒中的优势,塑造并建构城市化进程影像,本文从传播学的角度,以闽北“苏区”武夷山市洋庄乡大安、坑口村为例,探讨“自媒体”环境下塑造城市品牌影像的途径与方法。     

论新闻摄影的“语-图”互文———基于热奈特跨文本理论简

新闻摄影与文字之间存在着复杂的互文性关系。对新闻摄影的“语-图”互文现象的探讨,法国批评家热奈特的“跨文本性”理论给我们提供了一个很好的理论视角。新闻摄影具有“以图证文”、“以图示文”、“因图生文,从文至图”以及在“广义文本性”理论下新闻摄影与体裁之间的多层次互文性关系。此外,新闻与新闻摄影由于各自不同的原因丧失各自的语境,但它们又从彼此身上寻找回来,形成双重的承文本性关系。     

Computer-based multimedia testing: Effects of static and animated representational pictures and text modality

Static representational pictures (RPs) have been focused in research on the multimedia effect in testing and might be especially important in arithmetical word problems, which require a multi-stage mental processing to segment the task. To further highlight the task segments visually, dynamic visualizations could help. However, conventional animations might not apply to this context and the role of dynamic visualizations with temporal segmentations (i.e., animated RPs) is unexplored. This classroom experiment with 456 students investigated multimedia and modality effects in 24 mathematical word problems. Our 3 × 2 mixed design included three multimedia conditions (static RPs, animated RPs, and text-only) and two modality conditions (written text vs spoken text). We investigated effects on response correctness, metacognitive ratings, item-solving satisfaction and time on task. Both static and animated RPs increased response correctness, item-solving satisfaction, and metacognitive ratings compared to text-only. Time on task was affected in distinctive ways in both RP conditions and also varied depending on text modality. Spoken text barely increased response correctness in animated RP items but not at all in static RP items. Moderator analyses revealed that the effects of static and animated RPs on response correctness were dependent on the text modality but varied across school types and the level of mathematical prior knowledge. For students at non-academic-track schools or with low prior knowledge, static and animated RPs improved response correctness compared to text-only across both modalities. For students at academic-track schools or with high prior knowledge, mainly combinations of static or animated RPs with spoken text were effective.     

Unequal Forced-Intra-Refresh for robust video streaming

INTRODUCTION In the encoding or transcoding of video stream- ing, intra refresh is introduced as a non-normative error-resilience tool. Although the intra-refresh schemes based on the rate-distortion optimization (C?té et al., 2000; Stockhammer et al., 2002) are superior to the early heuristic intra-refresh strategies, these new schemes cannot yet accurately estimate the video distortion due to time-varying packet losses, and usually ignore the inter-frame error-propagation effect.

读图时代:语文思维训练的应对与发展

21世纪,人类进入了“读图时代”。图与文都是传播信息的工具。图像直接作用于人的视觉.消除了文字那种需要通过接受教育才能理解的间接性。从“文本”到“图本”的转化对人类思维能力的影响是深刻的,面对“读图时代”,语文教师应引导学生适应思维方式的转变,提高学生的阅读能力。

Investigating the Influence of Simultaneous– Versus Sequential–Text-Picture Presentation on Text-Picture Integration

This study investigated whether text-picture integration is facilitated when text and pictures are presented simultaneously instead of sequentially. Participants memorized general and specific sentences and pictures. It was expected that due to text-picture integration, participants should falsely recognize specific versions of the sentences and pictures even after having studied only their general versions before. Sentences and pictures were presented simultaneously or sequentially with the picture either preceding or following the corresponding sentence. Contrary to expectations, text-picture integration was only observed for picture recognition and was not influenced by temporal contiguity. Findings are explained by the use of simple materials that did not sufficiently tax working-memory capacity to allow for any benefit of a simultaneous text-picture presentation to occur.     

地理认知中的思维媒介

地理研究对象的特点决定了其认知需要视觉思维的操作,要以心理意象作为思维的基础,地理认知应该是以意象为表征基础的思维过程。受传统的以语言为思维媒介观念的影响,地理认知仍然强调语言的表达方式,因此必须改变思考问题的策略,考虑意象这一思维媒介在地理认知中的价值和作用,结合文献材料想象和构建适当的、有着清晰结构的心理图式或模型,并作透视或观察。
