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.

PROFILING AND POLICE LEGITIMACY: PROCEDURAL JUSTICE,ATTRIBUTIONS OF MOTIVE,AND ACCEPTANCE OF POLICE AUTHORITY*

This paper reports the results of four studies that investigate racial profiling as an attribution about police motives. Each study explores, first, the types of police behavior that heighten or lessen the occurrence of profiling attributions and, second, the consequences of such attributions. Results support prior studies in finding that judgments about whether the police are profiling are associated with the level of public support for the police. The studies then extend the analysis of subjective profiling judgments by examining their antecedents. The findings support the procedural justice hypothesis that the fairness with which the police exercise their authority influences whether members of the public view the police as profiling.

THE DELINQUENCY OF CHILDREN BORN TO YOUNG MOTHERS: RESULTS FROM THE ROCHESTER YOUTH DEVELOPMENT STUDY*

This paper examines the relationship between a mother's age at first childbirth and the delinquent behavior of her children. Using data from the Rochester Youth Development Study (RYDS), an ongoing longitudinal study of adolescent development, we found that children born to mothers who began childbearing at a young age were more prone to general delinquency, violence, and arrest than were children born to mothers who began childbearing when they were older. This “early first‐birth effect” was far larger in white and Hispanic families than in African‐American families. Mediating analyses found that the early first‐birth effect was most attributable to the unstable composition of families in which early childbearing occurs. That said, a substantial portion of the effect remains unmediated.

SEX‐BASED DISPARITIES IN FELONY DISPOSITIONS BEFORE VERSUS AFTER SENTENCING REFORM IN OHIO*

Extending Koons‐Witt's (2002) study of whether sex‐based disparities in imprisonment likelihoods changed under sentencing guidelines in Minnesota, we examined similar models for Ohio with additional analyses of felony conviction likelihoods and sentence length for 5,472 felony defendants from twenty‐four trial courts. The main effects of a defendant's sex on imprisonment were significant during both periods (unlike the Minnesota findings), consistent with a chivalry perspective. Random coefficient models revealed that these effects were similar across the twenty‐four jurisdictions. Analyses also revealed significant postguideline reductions in sentence length disparities based on a woman's race and number of dependent children, yet increased disparities in imprisonment likelihoods postguidelines based on a woman's race and whether she was convicted on drug charges. These and other findings are discussed in the context of the Ohio legislature's implementation of a sentencing scheme that retains considerably more judicial discretion relative to Minnesota's template.     

理论创新与思想路线

时于思想路线来说,理论创新应当是它的题中之义。然而由于历史的原因,毛泽东没有明确提出这个概念,理论界也没有意识到这个问题。邓小平提出的解放思想的理论使人们对思想路线的理解上升到一个新的水平,而江泽民提倡的理论创新又把人们对思想路线的认识向前推进到一个新的境界。
