Identity construction of suspects in telecom and internet fraud discourse: from a sociosemiotic perspective

ABSTRACT

As a new kind of contactless crime, the telecom and internet fraud has become a public hazard, with criminals targeting massive numbers of innocent victims. It is a prominent criminal problem that currently affects social stability and the sense of security of the public. Since the six Ministries and Commissions jointly cracked down the crime in 2016, the number of cases and the number of people deceived have decreased, but the occurrence and frequency has still been at a high rate, and the situation is deteriorating. Regardless of the scientific and technological means used by fraudsters, the main medium is language. From a sociosemiotic perspective, this study identifies that the criminal suspects use the discourse resources to fabricate false information and construct false identities through discursive practice, with the aim of achieving the communicative purpose of obtaining victims’ trust, tricking, deceiving and manipulating their victims into giving out confidential information and funds. This study, taking telecom fraud discourse as one type of genre, examines the dynamic process of selecting and constructing identities by manipulating related discourse resources and strategies in the social-cultural context. This study further provides a sociosemiotic solution to telecom fraud prevention.

Automated detection and classification of counterfeit banknotes using quantitative features captured by spectral-domain optical coherence tomography

Counterfeiting of banknotes is still a severe crime problem in many countries. One of the most significant issue for solving the crime is to classify the counterfeit types and identify the sources. Most of the current methods to classify counterfeit banknotes rely on manual examination that is time-consuming and labor-intensive. Moreover, these methods only detect surface features which can be easily imitated through advanced printing technology. In this study, an automated method based on optical coherence tomography (OCT) and machine-learning algorithms was proposed to classify different types of banknotes based on the internal features. A spectral-domain OCT (SD-OCT) system was employed for sub-surface imaging and quantitative assessment of banknotes. A total of 29 Chinese 100-Yuan banknotes were collected, in which 4 of them were real and 25 of them were counterfeiting by three different printing processes. Each banknote was imaged 10 times in 3 distinct regions, which resulted in a dataset of 290 samples. Each sample was characterized by extracting 2 A-scan (OCT signal intensity along depth) based features and 14B-scan (cross-sectional OCT images) based features. Several machine-learning models, including logistic regression (LR), support vector machines (SVM), K-nearest neighbor (KNN) and random forest (RF), were built and optimized as the classifiers that were trained using 203 samples and applied to predict 87 testing samples. The best performance was achieved by SVM classifier in which the sensitivity of 96.55% and specificity of 98.85% were obtained in discriminating between authentic and counterfeit banknotes, and the sensitivity of 94.67% and specificity of 98.22% were obtained in predicting the types of counterfeit banknotes. These classifiers were also evaluated using the receiver operating characteristic (ROC) curves. To the best of our knowledge, this is the first study where A-scan and B-scan derived features from OCT images have been used for the detection and classification of different types of counterfeit banknotes.     

动态商标及其显著性认定

纸质媒介为主导的传统视觉生活是以静态的传统商标为主，但随着互联网的发展和普及以及电子商务的迅猛发展，非传统的动态商标逐渐受到国际社会的广泛关注。动态商标是以数字媒介为载体和动感设计为基础，是属于广义上的可视性商标，是符合绝大多数国家商标法对商标的规定。动态商标从本质上讲属于心理的认知，是消费者对商标所代表的有关商品或服务信息的评价。强大的视觉冲击效果和周而复始的广告宣传，使得动态商标在消费者的“认知网络”的信息组块中形成“结点”，从而使动态商标获得显著性。

关联理论与中国口译职业化教育——分析对口译活动中三元关系的元认知对职业化的指导意义

中国的口译起步比较晚，却是一个契机——借鉴国际社会口译发展过程中经验与教训的契机。但由于语言与思维的差异，强行照套西方口译的发展规律无异于削足适履。文章从F．Pochhacker提出的Meta—level training（元认知教育）出发，融入笔译中的“关联理论”，将静止的四元素组合成三组相互独立又相互联系的动态三元关系，旨在为中国口译的职业化道路打开新的思路。     

强化检察委员会司法属性之路径探析

在检察委员会的规范化建设已取得明显成效的情况下,应当更多地关注检察委员会的司法属性问题和决策机制的改革完善。检察委员会改革应遵循司法规律,将民主、高效、权威设定为基本目标,通过优化组织体系、改革决策模式、建立责任机制、提升委员司法能力等强化其司法属性。在决策模式改革上,应借鉴吸纳审判合议制和党委票决制的合理内核,保证委员的"民主"地位、严格检察长的"集中"机制,确立一级检察委员会定案机制,以此增强检察委员会决策机制的司法属性。
