人性：西方法治思想之源及评析

西方法治的创设基点是:人性本恶,法治也就因人性恶而产生;性恶论是西方法治主义的根基,是西方法治思想的逻辑起点,同时也是分权制衡制度设计的基石。西方法律制度的构建是在人性恶的基本假设中推导而出的;西方法治发展和制度文明从此展开。     

Using anisotropic diffusion for efficient extraction of sensor noise in camera identification

Each digital camera has an intrinsic fingerprint that is unique to each camera. This device fingerprint can be extracted from an image and can be compared with a reference device fingerprint to determine the device origin. The complexity of the filters proposed to accomplish this is increasing. In this note, we use a relatively simple algorithm to extract the sensor noise from images. It has the advantages of being easy to implement and parallelize, and working faster than the wavelet filter that is common for this application. In addition, we compare the performance with a simple median filter and assess whether a previously proposed fingerprint enhancement technique improves results. Experiments are performed on approximately 7500 images originating from 69 cameras, and the results are compared with this often used wavelet filter. Despite the simplicity of the proposed method, the performance exceeds the common wavelet filter and reduces the time needed for the extraction.     

宪法解释方法的两种传统及其启示

宪法解释的重要性已经得到了普遍的认可,而在宪法解释方法的历史发展中,存在着两大分支:德国传统和美国传统,二者分别以文义解释和原旨主义为主导性解释方法。虽然两种传统有着诸多差异,但从20世纪以来却出现了趋同的倾向,以重视社会学解释方法为集中表现。在两种传统的差异与趋同中,中国宪法解释可以受到多方面的启示,包括回归宪法文本、期待个案发轫、扩展主体范围和重视社会效果等。     

How Language Can Influence Political Marketing Strategy and a Candidate's Image: Effect of Presidential Candidates' Language Intensity and Experience on College Students' Ratings of Source Credibility

The present study examines the effects of language intensity on presidential candidates' credibility. We manipulated language intensity levels and experience levels for hypothetical candidates for president of the United States. Manipulation checks confirmed the effectiveness of the experimental conditions. The dimensions of source credibility, character, and authoritativeness were confirmed using confirmatory factor analysis. Analysis of variance indicated that candidates using low-intensity language received higher scores on character than did candidates using high-intensity language. Experienced candidates received higher scores on authoritativeness than did inexperienced candidates. Implications for political marketing of candidates are discussed.     

The Effect of Time on Bone Fluorescence: Implications for Using Alternate Light Sources to Search for Skeletal Remains

Bones fluoresce when exposed to certain wavelengths of shortwave light, and this property can be useful in locating and sorting skeletal remains in forensic contexts. The proteins in bone collagen are largely responsible for its fluorescent properties, but these proteins degrade and denature over time. This study examined the fluorescence of bones from four temporal groups (recent, semi‐recent, ancient, and historic) ranging from 0 to 1064 years before present. Specimens were photographed under 490 nm wavelength light, and fluorescence was quantified by converting intensity to a gray scale value based on the RGB color model using ImageJ^® software. Significant (p < 0.05) differences were found in mean fluorescence between all four temporal groups, and a 0.324 coefficient of correlation indicates a significant (inverse) relationship between fluorescence and time. Bone fluorescence decreases with time, but some fluorescence is retained even in older samples. Fluorescence can therefore be reliably used in many modern skeletal remains searches.     

现代化视角下的大学生之公民教育——对党的十七大报告的解读

胡锦涛总书记在党的十七大报告中提出:加强公民意识教育,树立社会主义民主法治、自由平等、公平正义理念。这既为加强公民教育指明了方向,也界定了公民教育的内涵。大学生公民教育是公民教育的重要一环。大学生公民教育的价值寓于人性、市场经济、人民主权、法治国家以及社会自治的必然要求中。大学生公民教育的内容包括公民道德的养成与公民价值观的塑造、公民知识的传播与公民参与技能的训练这两大方面。当前,应以《思想道德修养与法律基础》为蓝本践行大学生公民教育,造就现代公民。

A City‐wide Investigation of the Isotopic Distribution and Source of Tap Waters for Forensic Human Geolocation Ground‐truthing

Human geolocation is prefaced on the accuracy of the geographic precision of mapped isotopic values for drinking water. As most people live in cities, it becomes important to understand city water supplies and how the isotopic values uniquely reflect that city. This study investigated the isotopic distribution of δ²H and δ¹⁸O from sourced tap waters that were collected from across the Metro Vancouver (MV) area (n = 135). The results revealed that the isotopic values reflect their water sources with a range of 5.3‰ for δ¹⁸O_tap and 29.3‰ for δ²H_tap for MV. The results indicate that individual cities need higher resolution studies to determine their tap water isotopic ranges, and a good understanding of the water supply network itself for human geolocation work. With an extended high‐resolution understanding of each city, human tissue may be compared with more certainty for geolocation.     

Identification of Mobile Phone and Analysis of Original Version of Videos through a Delay Time Analysis of Sound Signals from Mobile Phone Videos

This study designs a method of identifying the camera model used to take videos that are distributed through mobile phones and determines the original version of the mobile phone video for use as legal evidence. For this analysis, an experiment was conducted to find the unique characteristics of each mobile phone. The videos recorded by mobile phones were analyzed to establish the delay time of sound signals, and the differences between the delay times of sound signals for different mobile phones were traced by classifying their characteristics. Furthermore, the sound input signals for mobile phone videos used as legal evidence were analyzed to ascertain whether they have the unique characteristics of the original version. The objective of this study was to find a method for validating the use of mobile phone videos as legal evidence using mobile phones through differences in the delay times of sound input signals.
