Identification of Natural Images and Computer‐Generated Graphics Based on Statistical and Textural Features

To discriminate the acquisition pipelines of digital images, a novel scheme for the identification of natural images and computer‐generated graphics is proposed based on statistical and textural features. First, the differences between them are investigated from the view of statistics and texture, and 31 dimensions of feature are acquired for identification. Then, LIBSVM is used for the classification. Finally, the experimental results are presented. The results show that it can achieve an identification accuracy of 97.89% for computer‐generated graphics, and an identification accuracy of 97.75% for natural images. The analyses also demonstrate the proposed method has excellent performance, compared with some existing methods based only on statistical features or other features. The method has a great potential to be implemented for the identification of natural images and computer‐generated graphics.     

Who's Afraid of WikiLeaks? Missed Opportunities in Political Science Research

Leaked information, such as WikiLeaks’ Cablegate, constitutes a unique and valuable data source for researchers interested in a wide variety of policy‐oriented topics. Yet political scientists have avoided using leaked information in their research. This article argues that we can and should use leaked information as a data source in scholarly research. First, the methodological, ethical, and legal challenges related to the use of leaked information in research have been considered, concluding that none of these present serious obstacles. Second, how political scientists can use leaked information to generate novel and unique insights concerning political phenomena using a variety of quantitative and qualitative methods have been shown. Specifically, how leaked documents reveal important details concerning the Trans‐Pacific Partnership negotiations, and how leaked diplomatic cables highlight a significant disparity between the U.S. government's public attitude toward traditional knowledge and its private behavior have been demonstrated.

试论中国社区警务的构建

从一定意义上讲,中国是实践社区警务最早的国家。构建中国社区警务是必要的,也是可行的。构建社区警务,必须贯彻改革精神,解放思想,转变传统思想观念,对警务重心、警务模式和警务风格重新调整,强化基层基础工作,深化派出所和刑侦体制改革,并应建立与之配套的民警巡逻体制。

当今犯罪构成理论的八大矛盾

现今犯罪构成理论的基本理论和基本框架是正确的 ,但在一些细节上却存在不少矛盾 ,比如 ,犯罪构成定义认为 ,犯罪构成决定行为的社会危害性及其大小 ,这与事物的性质由事物的内在矛盾决定的原理相矛盾。再如 ,通说将犯罪客观方面称为犯罪构成的要件 ,将客观方面包含的行为、结果也称为客观要件 ,这与逻辑上的种属关系相矛盾。此外还有 ,犯罪客体的定义与犯罪客体的地位相矛盾、刑事责任能力与刑法理论相矛盾 ,等等。这些矛盾说明 ,现今的犯罪构成理论还不够完善

刑法中的正当化行为与犯罪构成关系的理性思考

与大陆法系、英美法系均将刑法中的正当化行为置于犯罪构成体系之中的做法所不同的是 ,刑法中的正当化行为是游离于我国传统的耦合式犯罪构成体系之外的一个“活泼元素”。这样的关系 ,与现代刑事法治的精神不相契合 ,实有认真检讨和改进的必要。英美法系双层次犯罪构成模式为刑法中的正当化行为的纳入 ,尤其是超法规的正当化行为的充分展开 ,不仅提供了极其广阔的空间 ,而且因赋予其程序要件的色彩 ,从而突出强调了程序正义的价值 ,推动了宪法在刑事领域的司法化。因之 ,借鉴英美法系双层次犯罪构成的结构模式 ,吸纳我国传统犯罪构成体系中的合理成份 ,实现经验与理性的沟通 ,应当成为改造我国传统的耦合式犯罪构成体系的努力方向。
