In anthropological and legal literature, the phenomenon termed ‘legal pluralism’ has been interpreted as a co-presence of legal orders which act in relation to their own ‘levels’ of referring ‘fields’. The Afghan normative network is generally described in terms of pluralism, where different normative systems such as customs, shari’a (Islamic law), state laws and principles deriving from international standard of law (e.g., human rights) coexist. In order to address the crucial question of access to justice, in this article, I stress the category of legal pluralism by introducing the hypothesis of an inaccessible normative pluralism as a key concept to capture the structural injustices of which Afghans are victims. Access to justice can be considered a foundational element of every legal project. Globally, the debates concerning the diffusion and application of human rights develop at the same time ideologically, politically, and pragmatically. Today in Afghanistan, these levels are expressed in all their complexity and ambivalence. It is therefore particularly significant to closely observe the work done by the Afghanistan Independent Human Rights Commission and to discuss the issue of human rights by starting from a reflection on what might be defined a socio-normative condition of inaccessibility.  相似文献

This article approaches a position of delving into the thoughts of those who commit murder serially. The information comes from a variety of sources which include research literature, theory examination and most importantly, serial murderers themselves. More than 400 cases of serial fatal violence as well as interviews with incarcerated serial killers were utilized. Important issues such as locus of motives, expected gains, victim selection processes, planning of the event, the murder event itself, and organization and disorganization of the kill are also discussed. While admitting that serial killers have never been rehabilitated, a call is directed toward a better understanding of the mind of the serial murderer.  相似文献

The objective of this study was to determine the correlates of substantiated psychological maltreatment (PMT) in Canada on functions of maltreatment characteristics, child profile, household profile, and child protection services interventions. This study is based on a secondary analysis of data collected in the second Canadian Incidence Study. PMT investigations were categorized into six groups: emotional abuse, emotional neglect, and other maltreatment as single form, and these same three groups when they co-occurred with another form of maltreatment. Six logistic regressions, comparing all pairs of groups, were carried out. Cases of PMT (single form) were more chronic and associated with greater adverse emotional impact than other forms of maltreatment. Mothers of psychologically maltreated children had more mental health issues. Emotional neglect cases were more complex (e.g., substance abuse, mental health, and social housing). The three co-occurrent groups present more negative factors but more risk factors are observed when PMT are also observed (e.g., emotional harm, alcohol abuse, housing problems, chronicity, and referral to other services).  相似文献

In prosecution, Belgian judiciary currently uses outdated yield figures (28.1g per plant, sold at € 3/g at grower level) for fining illicit indoor cannabis plantations. Using state-of-the-art cultivation techniques, our growth experiments showed that yield is better expressed in g/m(2) cultivated surface area rather than in g per plant, and that yield varies significantly between different cannabis strains. It was found that the lower-bound of the one-sided 95% confidence interval of the yield of an indoor cannabis plantation can be set at 575 g/m(2). Prices and pricing mechanisms were investigated using interviews with respondents selected through snowball sampling. Results reveal that (i) the Belgian cannabis market chain is highly complex; (ii) unit prices are predominantly determined by transaction sizes; but also (iii) a set of product- and socially-related price-fixing mechanisms have an equally important role. At grower level, respondents reported prices for 1 g of dry cannabis buds to range € 3.00-4.25.  相似文献

The interpretation of bloodstain patterns at crime scenes has received increased attention in recent years. Important to an understanding of this is knowledge of the fundamentals of blood droplet formation and impact dynamics. A review of the literature reveals that a considerable amount of work has been done with aqueous drop dynamics. Workers in the forensic science area seem to have been unaware of this. In addition, some of the most important and comprehensive early work with blood droplet dynamics seems to have been forgotten. It is not cited in more recent publications dealing with bloodstain pattern interpretation. This literature is reviewed and discussed as well. The present study presents results of experiments with blood droplet dynamics and high-speed photographs of blood droplet impacts on stationary target surfaces. Some longstanding misconceptions of importance to forensic scientists engaged in crime scene reconstruction are discussed.  相似文献

The concept for a semi-automated processing system for DNA analysis of crime scene samples was developed at the Landeskriminalamt Baden-Württemberg (LKA BW) and comprises the extraction of genomic DNA from human cells by ChargeSwitch® magnetic bead technology (CST), quantification of purified DNA by real-time PCR, amplification of short tandem repeats (STRs) by PCR and DNA fragment length analysis of STRs by capillary electrophoresis. Three liquid handling workstations from Tecan, a real-time PCR device and a 16-channel capillary electrophoresis (CE) system, both from Applied Biosystems (AB), are linked via laboratory data network. Transmission and management of sample and analysis data is enabled by a Laboratory Information and Management System (LIMS). Suitability for a wide range of stain types, early exclusion of DNA-free samples, barcode sample identification and prevention of cross-contaminations guarantee efficiency and high quality standards.  相似文献
