韩国人对华负面认知与中国对韩公共外交途径

中韩两国关系自建交以来在许多方面取得了飞速发展,但近些年,两国关系由"暖"变"冷",原因是多方面的,其中韩国人对中国形象的负面认知,产生了很大的负面影响。对此,我们不能视而不见或避而不谈,而应积极加强对韩公共外交,促进两国友好关系顺利发展。韩国是中国的重要邻国,中韩两国关系良好发展的意义不仅局限在两国关系上,它对于改善东北亚地区的安全局势也具有不可忽视的作用。本文主要就韩国人对中国形象的负面认知及其对中韩关系所起的负面影响作用以及应对之策,做简要分析和探讨。     

Racial and ethnic disparity in pretrial criminal processing

This study uses data on the processing of felony defendants in large urban courts to analyze racial and ethnic disparities in pretrial processing. There are three major findings. First, racial disparity is most notable during the decision to deny bail and for defendants charged with violent crimes. Second, ethnic disparity is most notable during the decision to grant a non‐financial release and for defendants charged with drug crimes. Third, when there is disparity in the treatment of Black and Latino defendants with similar legal characteristics, Latinos always receive the less beneficial decisions. These findings are consistent with the theoretical perspective offered, which suggests that stereotypes influence criminal processing when their specific content is made salient by either the concerns relevant to a particular processing decision or the crime type of a defendant’s primary charge.

Shoeprint image retrieval and crime scene shoeprint image linking by using convolutional neural network and normalized cross correlation

A shoeprint image retrieval process aims to identify and match images of shoeprints found at crime scenes with shoeprint images from a known reference database. It is a challenging problem in the forensic discipline of footwear analysis because a shoeprint found at the crime scene is often imperfect. Recovered shoeprints may be partial, distorted, left on surfaces that do not mark easily, or perhaps come from shoes that do not transfer marks easily. In this study, we present a shoeprint retrieval method by using a convolutional neural network (CNN) and normalized cross-correlation (NCC). A pre-trained CNN was used to extract features from the pre-processed shoeprint images. We then employed NCC to compute a similarity score based on the extracted image features. We achieved a retrieval accuracy of 82% in our experiments, where a “successful” retrieval means that the ground truth image was returned in the top 1% of returned images. We also extend our shoeprint retrieval method to the problem of linking shoeprints recovered from crime scenes. This new method can provide a linkage between two crime scenes if the two recovered shoeprints originated from the same shoe. This new method achieved a retrieval accuracy of 88.99% in the top 20% of returned images.     

Macroscopic assessment of environmental trace evidence dynamics in forensic settings

Environmental trace evidence offers useful circumstantial intelligence to link persons and scenes of forensic interest. An increasing empirical research base is dedicated towards understanding the transfer and persistence dynamics of environmental indicators including pollen, soils, and diatoms, within a diverse range of experimental frameworks. This paper presents two discrete studies exploring transfer and persistence of soils and sediments on footwear and diatomaceous earth adhered to clothing in forensically pertinent scenarios. Variables including sediment type, foot position, clothing type, and body positioning were also explored throughout. Both experiments incorporated a field-based methodology during the sampling effort. Photographs were collected of an initial transfer sample and of a retained assemblage following hours, days, and up to one-week of wear, facilitating macroscopic assessment of trace evidence dynamics. All images were processed using accessible, open-source software before spatial analysis of evidence distribution within and temporal assessment (% retention) upon each evidential surface. The results highlighted consistent loss of transferred sediment from footwear with significantly greater retention of loamy clay soil than dune sand which was absent beyond 24 h of wear. Loss was not influenced by wearer gait but was more rapid from those areas of the shoe sole in direct contact with the ground. Diatomaceous earth was retrieved from all three clothing types tested after one week – significant losses of material occurred before 48 h with a consistent assemblage identified beyond this. Denim was significantly more effective than acrylic and fleece for diatomaceous earth retention and significantly more material was lost from clothing worn on the lower body. These findings highlight the value of using visual environmental markers and a macroscopic analytical approach during the investigation of environmental trace dynamics. The methodology offers a novel, non-destructive assessment of soil and diatom transfer and persistence, complementing more extensive laboratory-based examinations to ensure the development of a well-rounded research base within the forensic sciences.     

An Approach to Speaker Identification

This presentation will provide standards upon which any attempts to meet the challenge of identifying speakers by voice should be based. It is organized into a model based on (i) application of a rigorous research program validating the system, (ii) an upgrading of the organization of the SI area, and (iii) exploitation of new technology. The second part of the presentation will describe an illustrative speech/voice approach to SI development. This effort is also based on an extensive corpus of research. It is suggested that application of the cited standards, plus the illustrative model, will permit reasonable progress to be made. Finally, a number of procedural recommendations are made; they should enhance the efficacy of the proposed approach.     

Passive forensics in image and video using noise features: A review

Due to present of enormous free image and video editing software on the Internet, tampering of digital images and videos have become very easy. Validating the integrity of images or videos and detecting any attempt of forgery without use of active forensic technique such as Digital Signature or Digital Watermark is a big challenge to researchers. Passive forensic techniques, unlike active techniques, do not need any preembeded information about the image or video. The proposed paper presents a comprehensive review of the recent developments in the field of digital image and video forensic using noise features. The previously existing methods of image and video forensics proved the importance of noises and encourage us for the study and perform extensive research in this field. Moreover, in this paper, forensic task cover mainly source identification and forgery detection in the image and video using noise features. Thus, various source identification and forgery detection methods using noise features are reviewed and compared in this paper for image and video. The overall objective of this paper is to give researchers a broad perspective on various aspects of image and video forensics using noise features. Conclusion part of this paper discusses about the importance of noise features and the challenges encountered by different image and video forensic method using noise features.

If i Go There Will Be Trouble,If i Stay There Will Be Double: Revenge Porn,Domestic Violence,and Family Offenses

New York State's current lack of legislation criminalizing the threat of revenge porn allows repetitive, invasive, and embarrassing attacks on the morality and sexuality of victims. This can have a severe impact on survivors of domestic violence who are prevented from leaving dangerous situations by threats of dissemination. Victims of revenge porn and domestic violence often face isolation, threats of violence, and thoughts of suicide. This Note proposes that threats of revenge porn become family offenses under the New York Family Court Act § 812.
