组织出卖人体器官犯罪的认定与侦查

买卖人体器官是近年来人民群众反响强烈的严重刑事犯罪行为。为加大刑事打击力度,我国《刑法修正案（八）》新增了组织出卖人体器官罪。与其他组织型团伙犯罪不同,此类犯罪有其独有特点,给公安机关认定和侦查带来一定难度,必须选好切入点和突破口,并将侦查和取证结合起来,提高快侦快破和严打效率,切实维护人民群众生命健康安全。     

Transnational governance of cybersecurity: policy challenges and global inequalities in cyber capacity building

Abstract

Connectivity infrastructure is constantly expanding, increasing internet access across countries, regions and socio-political contexts. Given the fast-changing geography of the internet, there is a growing demand to strengthen cyber capacity beyond national frameworks, in order to develop a transnationally coherent and coordinated governance approach to cybersecurity. In this context, cyber capacity building initiatives are increasingly central in international debates, with the ambition to support countries in the Global South in fostering their cybersecurity strategy from technical and policy perspectives. This article discusses the key factors explaining states’ efforts to enhance their cyber capacity. Based on a cross-national quantitative research approach, the findings contradict international relations (IR)-derived approaches to cybersecurity, which assume that countries develop their cyber capacity according to external security threats, domestic politics or norms. In line with existing research on the role that science plays in policymaking processes more broadly, our results suggest instead that a country’s science and technical knowledge is the most robust explanation for that state’s cyber capacity level. These findings emphasise the need for policymakers to support countries in the Global South in developing their cyber capacity beyond national security paradigms by strengthening education and technical skills in contexts lacking in this resource.     

Examination of heterogeneous crossing sequences between toner and rollerball pen strokes by digital microscopy and 3-D laser profilometry

The determination of line crossing sequences between rollerball pens and laser printers presents difficulties that may not be overcome using traditional techniques. This research aimed to study the potential of digital microscopy and 3-D laser profilometry to determine line crossing sequences between a toner and an aqueous ink line. Different paper types, rollerball pens, and writing pressure were tested. Correct opinions of the sequence were given for all case scenarios, using both techniques. When the toner was printed before the ink, a light reflection was observed in all crossing specimens, while this was never observed in the other sequence types. The 3-D laser profilometry, more time-consuming, presented the main advantage of providing quantitative results. The findings confirm the potential of the 3-D laser profilometry and demonstrate the efficiency of digital microscopy as a new technique for determining the sequence of line crossings involving rollerball pen ink and toner.

Current practices by forensic anthropologists in adult skeletal age estimation

When determining an age estimate from adult skeletal remains, forensic anthropologists face a series of methodological choices. These decisions, such as which skeletal region to evaluate, which methods to apply, what statistical information to use, and how to combine information from multiple methods, ultimately impacts the final reported age estimate. In this study, a questionnaire was administered to 145 forensic anthropologists, documenting current trends in adult age at death estimation procedures used throughout the field. Results indicate that the Suchey-Brooks pubic symphysis method (1990) remains the most highly favored aging technique, with cranial sutures and dental wear being the least preferred, regardless of experience. The majority of respondents stated that they vary their skeletal age estimate process case-by-case and ultimately present to officials both a narrow and broad possible age range. Overall, respondents displayed a very high degree of variation in how they generate their age estimates, and indicated that experience and expertise play a large role in skeletal age estimates.     

Auto Theft and Restrictive Deterrence

Although researchers have examined the attributes that make offenders more or less responsive to sanction threats, far less attention has centered on the manner in which responsiveness can lead to less detectible crime, or perhaps even more overall crime. Restrictive deterrence is the concept that explains this paradox. We explore it here using qualitative interviews with 35 active auto thieves. Findings suggest that auto thieves' restrictively deterrent decision-making strategies fell into three broad categories: discretionary target selection, normalcy illusions, and defiance. Discussion focuses on the data's conceptual implications for restrictive deterrence and offender decision-making.     

Development of a harmonised method for the profiling of amphetamines VI: Evaluation of methods for comparison of amphetamine

Amphetamine samples were analysed by gas chromatography-mass spectrometry (GC-MS), and the peak areas of 33 target compounds were transformed by applying various pretreatment techniques. The objective was to optimise the ability of a number of distance metrics to establish links between samples of amphetamine originating from the same batch (henceforth referred to as linked distances). Furthermore, partial least squares discriminant analysis (PLS-DA) was used to evaluate the effects of various pretreatment methods on separation of amphetamine batches synthesised by the Leuckart reaction, reductive amination of benzyl methyl ketone, and the nitrostyrene route. The most efficient way to pretreat GC-MS data varied for the different distance metrics, although best results were obtained when data were normalised to the sum of peak areas, and either the fourth root or a logarithm was applied to the normalised data. When pretreating normalised data by fourth root transformation, Pearson correlation was the distance metric that was most successful at finding linked samples. Normalisation and the use of fourth root also represented the best method of pretreating data when employing PLS-DA to separate samples synthesised by different routes. To achieve a faster and more user-friendly procedure for evaluating chromatograms, experiments were performed in which the number of target compounds used to compare samples was reduced. The effect of each compound that was removed was studied by applying PLS-DA and by using Pearson correlation to calculate linked distances as well as unlinked distances (between samples from different batches of amphetamine). Considering both links between samples from the same batch and separation of samples synthesised by different routes, the best results were obtained with the data set comprising 26 compounds. Finally, it was found that the profiling method developed in this work was superior to an existing technique with respect to separating linked and unlinked distances.

The diverse domains of quantified selves: self-tracking modes and dataveillance

The concept of self-tracking has recently begun to emerge in discussions of ways in which people can record specific features of their lives, often using digital technologies, to monitor, evaluate and optimize themselves. There is evidence that the personal data that are generated by the digital surveillance of individuals (dataveillance) are now used by a range of actors and agencies in diverse contexts. This paper examines the ‘function creep’ of self-tracking by outlining five modes that have emerged: private, communal, pushed, imposed and exploited. The analysis draws upon theoretical perspectives on concepts of selfhood, citizenship, dataveillance and the global digital data economy in discussing the wider socio-cultural implications of the emergence and development of these modes of self-tracking.
