A Simple Computer‐assisted Quantification of Contrast in a Fingerprint

A simple method for quantification of contrast in a fingerprint is proposed. Contrast is defined as the average difference in intensity of pixels between valleys and ridges in a fingerprint. It is quantified from a scanner‐acquired image of the fingerprint using a histogram function of Adobe Photoshop. The method was validated with black inked prints and marks developed with aluminum powder. Moreover, we tested resistance of the method to rater‐dependent errors and dependence of the measurements on the resolution of an image and the model of the scanner. For both groups of fingerprints, the method gave coherent and easily interpretable quantitative values for contrast. There were no significant differences between measurements performed by different raters and by the same rater in a test–retest procedure. However, the method was found to be instrument dependent, as measurements were significantly affected by image resolution and the model of the scanner.     

Some reflections on the duality of regime for software protection in the European Union

Although the framework for protection of computer programs has been established in the European Union more than two decades ago, it has not undergone any major changes. Opinions of Advocate General Yves Bot have convinced the Court to advance the concept of the plurality of copyright regimes applicable to software: source code, object code and documentation would be protected under the Software Directive, whereas interfaces, programming languages, data formats and software manuals are dealt with as literary works under the InfoSoc Directive. In SAS Institute v WPL, the Court also ruled that copyright in a computer program cannot be infringed where the lawful acquirer of the license neither decompiled the object code nor copied the source code of the computer program, but merely studied, observed and tested that program in order to reproduce its functionality in a second program. This ruling paves the way and acknowledges the reverse engineering efforts on the Old Continent.     

Is it Fair to Share? Perceptions of Fairness in the Division of Housework Among Couples in 22 Countries

This study explores the relationship between the actual division of housework and men’s and women’s perceived fairness in this regard. The central question is how the actual sharing of housework influences the perceptions of fairness in the division of housework. It is hypothesised that the perceptions of fairness differ between policy models. In countries where gender equality has been more present on the political agenda and dual-earner policies have been introduced, people are expected to be more sensitive to an unfair sharing or division of housework. By analysing the relationship between actual division of housework and perceptions of fairness in household work for 22 countries representing different family policy models, the study takes on a comparative perspective with the purpose of analysing the normative impact of policy. The analysis draws on data from the 2002 round of the International Social Survey Programme on family and changing gender roles. The results show that in countries that have promoted gender equality through the introduction of policies with an aim to promote dual roles in work and family, both women and men are more sensitive to an unfair division of household labour. The difference between perceptions in the different policy models is greater among men than among women, indicating that a politicization of the dual-earner family is more important for men’s equity perceptions than women’s.     

Changing Control of the Open Drug Scenes in Oslo— Crime,Welfare, Immigration Control,or a Combination?

Over the last few years there has been a societal move away from a perception of drug users as criminals to a perception of the users as sick. Contrary to what one may expect from such a change, reported drug crimes against the penal code are at record-high levels. It is the contradictory inherent in these tendencies that will be emphasized and highlighted in this article. The open drug scenes in Oslo and the police control of the scenes have changed. During the last few years there has been a growing element of foreign citizens in the drug scenes, and the police control has focused on the foreigners. Could part of the explanation of the contradictions be that there is a differentiation of how the different users are handled? Are there different forms of social control employed toward Norwegian and foreign actors in the open drug scenes? This article puts forward arguments that this is actually the case, driven by a consistent association of foreign actors in the drug scene with organized crime, and a stricter Norwegian legislation and approach to immigration questions, with a tendency toward a conflation of immigration and criminal law.     

Cold War Kitchen: Americanization,technology, and European users,by Ruth Oldenziel & Karin Zachmann

Abstract

This article concerns women who crossed a frontier both literally, by travelling to Paris – the art centre of the world in about 1900 – and symbolically, by training to be artists in ways which were not open to earlier generations. Paris provided a cosmopolitan environment and the article includes references to women of several nationalities, but gives particular prominence to Scottish women artists as a doubly marginalised group. By considering both their relation to academic training and to the avant-garde, it seeks to explain the comparative obscurity of these first-generation artists and suggests that they often became professionals, but without making the breakthrough to fame.     

Application of capillary electrophoresis to examination of color inkjet printing inks for forensic purposes

In the process of questioned document examination, the discrimination of inkjet printing inks is becoming more necessary due to increasingly frequent counterfeiting of documents printed by inkjet printers. Therefore, a method based on micellar electrophoretic capillary chromatography (MECC) has been developed and applied to analysis of such inks extracted from paper. With the use of an optimized and validated analytical procedure, multielectropherograms of inks taken from various models of printers made by various producers (Hewlett-Packard, Epson, Brother, Lexmark and Canon) were created. It was shown that effective differentiation of individual inks was possible in terms of migration time, order and specific shapes of characteristic peaks. By comparison of recorded UV-Vis spectra, the identification of main dyes was also achievable. The usefulness of the method was confirmed by an intralaboratory test of utility, in which several forged printouts were successfully examined. The obtained results proved that the proposed procedure is a useful tool that could be applied to ink discrimination and group identification of dyes originating from inkjet printing inks. Consequently, the developed method can be applied in the forensic field, including investigation of the authenticity of documents.     

Analysis of friction ridge evidence for trace amounts of paracetamol in various pharmaceutical industries by Raman spectroscopy

The detection of potentially harmful substances presents a multifaceted challenge. On one hand, it can directly save lives, on the other, it can significantly aid and enhance police work, thereby increasing the effectiveness of investigations. The research conducted in this study primarily aims to identify paracetamol in fingerprints, considering situations involving direct contact of a person with paracetamol either chronically or in a single dose. The identification procedure presented, utilizing Raman spectroscopy, aims to rapidly detect the xenobiotic following ingestion by an individual, which involves touching the tablet with their fingers—this can be termed as touch evidence in forensic science investigations. Additionally, the authors focus on assessing the impact of additives present in drugs containing paracetamol as the main active ingredient. The screening results obtained will enable us to analyze the composition of drugs in terms of potentially toxic substances, and their influence on the physicochemical activity of the active substance. We successfully identified the paracetamol molecule using a noninvasive forensic trace detection method. Samples in the form of common drugs containing 500 mg of paracetamol were studied. Throughout the study, comprehensive validation of the method was ensured through the utilization of a statistical model, which excluded sensitivity to the presence of other substances, whether additives or from the external environment. The proposed approach to trace the content of substances in fingerprint using Raman scattering analysis provides a useful starting point to enhance current analytical methods not only in forensic science but also in toxicology.     

First practical applications of eye temperature measurements for estimation of the time of death in casework. Report of three cases

This paper presents first three successive cases of death where at scene measurements of the internal eyeball temperature soon after death allowed to precisely estimate the times of deaths based on this data (33.1°C, 32.2°C and 29.5°C, respectively), which were later confirmed during the police investigation. Simultaneously the rectal temperatures in all three cases were measured and appeared to be between 36.3 and 36.8°C-reflecting a living individual's body temperature. Thanks to a significantly faster postmortem decrease of the eye temperature and a residual or nonexistent plateau effect affecting the eye, using the formula developed in previous comprehensive studies in pigs, the time of death in real cases could be estimated with good precision: 1 h 33 min, 2 h 24 min and 3 h 17 min since death respectively. The actual TOD established during investigation appeared to be: between 1 h 30 min and 1 h 50 min in case 1; 1 h 55 min in case 2 and between 2 h 55 min and 3 h 05 min in case 3. Such precise estimation, mainly due to the plateau effect lasting up to a few hours, could not have been done based only on rectal temperature, commonly measured in forensic practice.     

E-Commerce and Privacy Issues: An Analysis of the Personal Data Protection Bill

One of the concerns of e-commerce is the need to maintain users' privacy online. The usage of technical means to track down user's surfing and purchasing tendencies by the use of cookies, and sniffers to capture data while in the course of transmissions, has raised significant privacy issues. These anonymous data minings, although they may not necessarily bring harm to customers, nevertheless are a form of intrusion into one's privacy in cyberspace. In the US, the Federal Trade Commission has submitted a self-regulatory plan to require Web advertising companies to notify consumers of their Internet profiling activities and to give the customers the chance to choose whether information about Web activities and interests can be gathered anonymously. It is for this purpose that the Malaysian legislators devised the Personal Data Protection Bill. The importance of this is made clear in the explanatory statement of the personal data protection bill in Malaysia. The draft bill makes the law in Malaysia closer to the EU regime, which chooses legislation over self-regulation in this area. The purpose of this paper is to examine the nature, manner and scope of personal data protection under the Malaysian Bill.
