Influence of WTO decisions on international intellectual property

Legal context: The task of harmonization in the IP framework is currently atrisk. This conclusion is shown by the way EU Member States have recentlyenacted Directive 2001/29 on the harmonization of certain aspectsof copyright and related rights on the information society.Particularly, no Member State seems to have considered the interpretationof the three-step test of the Berne Convention given in 2000by the WTO panel, notwithstanding its importance. Moreover, three recent opinions of the French Cour de Cassation,the French Conseil Constitutionnel, and the German Federal Courtof Justice appear not to have endorsed the WTO's interpretationof the three-step test. This scenario confirms the impressionthat the international framework is devoid of any degree ofharmonization. Key points: Although the aims of certainty and predictability in the internationaltrading system are among its main tasks, the World Trade Organizationhas not yet tackled the plight of harmonization, preferringa political approach to smooth conflicts and disputes. Yet,the World Trade Organization has recently taken important stepsthat seem to herald a new attitude. In United States—Sections301-310 of the Trade Act of 1974, the World Trade Organizationdismissed the traditional deference towards national legislations.In addition, at international and national levels, the AlleghenyLudlum and Softwood Lumber cases aligned their interpretationsto that of the World Trade Organization.

中国死刑复核程序的检讨与改进

1980年以来,部分死刑案件核准权被下放使死刑复核程序名存实亡,立法上的疏漏和诉讼构造的缺失造成死刑复核程序难以起到最后的程序保障作用。试就完善立法、收回死刑核准权和改进死刑复核程序等三个方面的问题进行分析和探讨。     

Wavelet Analysis of Resultant Velocity Belonging to Genuine and Forged Signatures

This study presents a wavelet analysis of resultant velocity features belonging to genuine and forged groups of signature sample. Signatures of individuals were initially classified based on visual human perceptions of their relative sizes, complexities, and legibilities of the genuine counterparts. Then, the resultant velocity was extracted and modeled through wavelet analysis from each sample. The wavelet signal was decomposed into several layers based on maximum overlap discrete wavelet transform (MODWT). Next, the zero crossing rate features were calculated from all the high wavelet sub‐bands. A total of seven hypotheses were then tested using a two‐way ANOVA testing methodology. Of these, four hypotheses were conducted to test for significance differences between distributions. In addition, three hypotheses were run to provide test for interaction between two factors of signature authentication versus perceived classification. The results demonstrated that both feature distributions belonging to genuine and forged groups of samples cannot be distinguished by themselves. Instead, they were significantly different under the influence of two other inherent factors, namely perceived size and legibility. Such new findings are useful information particularly in providing bases for forensic justifications in establishing the authenticity of handwritten signature specimens.     

X‐ray Powder Diffraction for Characterization of Raw Materials in Banknotes

We report about the X‐ray powder diffraction characterization of crystalline materials used to produce genuine and counterfeit banknotes, performed with a single‐crystal diffractometer that permits fast and nondestructive measurements in different 0.5‐mm sized areas; 20‐euro denomination genuine banknotes were analyzed, and results were compared with counterfeit banknotes. The analysis shows that the papers used to print real banknotes are composed, as expected, of cotton‐based cellulose and titanium dioxide as crystalline additive, but different polymorphs of TiO₂ for different emission countries are evidenced. The counterfeit banknotes are composed of cellulose based on wood pulp; moreover, an unexpected significant quantity of TiO₂ was found to be mixed with calcite, indicating that the paper employed by forgers is not simply a common low‐cost type. The crystalline index and intensity ratios between the peaks attributable to cellulose and fillers can provide additional information to trace back paper suppliers for forensic purposes.     

A Preliminary Study on Sources of Banding Artifacts for the Identification of Monochromatic Laser Printers,

The analysis of questioned documents printed with monochromatic toner has been a great challenge to document examiners. Banding artifacts, which are often perceived in the outputs of laser printers, could be a solution to the identification of printers. In this study, sources other than the gear transmission errors were discovered for some primary banding frequency components. By detecting the angular velocity variation of photosensitive drums and other rotating parts of the tested printers and comparing them with the banding signals extracted from the printouts, the authors located the sources of banding frequency components. It was shown that the sources of some primary and persistent banding signals, which were previously unknown, were traced to the periodic velocity variations of the motors or the timing belts. As inherent signatures, banding artifacts could be promising features for discriminating documents printed by individual laser printers.     

非领导职务公务员考核量化管理模型构建及实现路径

目前,非领导职务公务员考核存在定性多、定量少,主观因素多、客观标准少等突出问题,缺乏一套科学、完整、民主参与、可操作性强的考核管理体系。因此,要解决考核的合理性与可行性之间的矛盾,就应当在科学理论指导下,运用先进的绩效考核方法,构建非领导职务公务员考核量化管理模型,积极探索切实可行的实现路径。
