We report a case where an alleged father (AF) attempted to substitute someone else's saliva sample for his reference sample in a paternity analysis. Buccal cells were collected from the AF and the child, and DNA analysis was performed using an autosomal STR loci (Identifiler). The profile from the AF showed extra peaks in some loci, as well as a much higher "X" allele peak relative to the "Y" allele peak at the amelogenin locus. After conducting reanalysis by another technician with another set of positive and negative controls, it was concluded that the only source of the mixed profile was by intentional introduction by the AF, at the time of sampling, of some foreign human biological material, most likely saliva from a woman. Owing to the inconclusive results, when the AF was called back to the lab and the peculiar results were explained to him, he admitted that he had introduced into his mouth saliva from another person in an attempt to be excluded as the father of the child. Although tampering with DNA reference samples is not common, some individuals may attempt to contaminate or otherwise adulterate specimens before DNA tests. Personnel responsible for sampling should be aware of this possibility and should try to establish procedures to avoid the problem. 相似文献

Difference-in-difference methods are being increasingly used to analyze the impact of mergers on pricing and other market equilibrium outcomes. Using evidence from an exogenous merger between two retail gasoline companies in a specific market in Spain, this paper shows how concentration did not lead to a price increase. In fact, the conjectural variation model concludes that the existence of a collusive agreement before and after the merger accounts for this result, rather than the existence of efficient gains. This result may explain empirical evidence reported in the literature according to which mergers between firms do not have significant effects on prices. 相似文献

Soil vestiges might provide information about a crime scene. The Rietveld method with X‐ray diffraction data (RM‐XRD) is a nondestructive technique that makes it possible to characterize minerals present in the soils. Soil clays from the metropolitan region of Curitiba (Brazil) were submitted to DCB treatment and analyzed using XRD with CuKα radiation in the step‐scan mode (0.02° 2θ/5 s). The GSAS+EXPGUI software was used for RM refinement. The RM‐XRD results, together with the principal component analysis (PCA) (52.6% total variance), showed the kaolinite predominance in most analyzed samples and the highest quartz contents in “site 1.” Higher anatase, and gibbsite and muscovite contents influenced discrimination, mainly in “site 3” and “site 1,” respectively. These results were enough to discriminate clays of four sites and two horizons using a reduced amount of sample showing that the technique can be applied to the investigation into soil vestiges. 相似文献

When faced with commingled remains, it might be assumed that a more “masculine” pelvis is associated with a more “masculine” cranium, but this relationship has not been specifically tested. This study uses geometric morphometric analyses of pelvic and cranial landmarks to assess whether there is an intra‐individual relationship between the degrees of sexual expression in these two skeletal regions. Principal component and discriminant function scores were used to assess sexual dimorphism in 113 U.S. Black individuals. Correlation values and partial least squares regression (PLS) were used to evaluate intra‐individual relationships. Results indicate that the os coxae is more sexually dimorphic than the cranium, with element shape being more sexually dimorphic than size. PLS and correlation results suggest no significant intra‐individual relationship between pelvic and cranial sexual size or shape expression. Thus, in commingled situations, associations between these skeletal elements cannot be inferred based on degree of “masculinity.” 相似文献

Critical criminologists have challenged the utility of efforts to reform the criminal justice system for decades, including strong calls to abolish the prison system. More recently, the rebellions in Ferguson, Baltimore, Milwaukee, and Charlotte have made racialized police violence and police reform issues of national concern. In this article, we examine abolitionist claims aimed at law enforcement institutions in the aftermath of Ferguson and other subsequent rebellions. We consider the implications for abolitionist organizing when the institution of law enforcement, rather than prisons, becomes the explicit target of our movement(s). How are groups theorizing and practicing police abolition and how does this align with, challenge, or expand past conceptualizations of abolition? To answer this question, first we sketch the broad parameters of abolitionist thought, particularly as it is taken up in the disciplines of political theory and criminology. Second, we analyze an emergent praxis of police abolition that revolves around the call to disband, disempower, and disarm law enforcement institutions. We argue that by attacking the police as an institution, by challenging its very right to exist, the contemporary abolitionist movement contains the potential to radically transform society. In this spirit, we amplify abolitionist praxis that (1) aims directly at the police as an institution, (2) seeks to dismantle the racial capitalist order, (3) adopts uncompromising positions that resist liberal attempts at co-optation, incorporation, and/or reconciliation, and (4) creates alterative democratic spaces that directly challenge the legitimacy of the police. 相似文献

Uberrima Fides is a legal doctrine that governs insurance contracts and expects all parties to the insurance agreement to act in good faith by declaring all material facts relative to a policy. The doctrine originated in England in 1766 with the case Carter v Boehm ruled by Lord Mansfield. Ever since, it has become, with some differences in interpretation, a cornerstone of insurance relationships around the world. The role that trust plays within it, however, is not simple and should not be taken for granted. While it is expected that an idea of trust represents an order of truth, trust in itself is the outcome of a complex negotiation of moral orders. Semiotically, trust operates here not as a Kantian category for the understanding but as a signifier of an order of truth that upholds the possibility for insurance relationships. Trust, as sign, operates as a condition of possibility for the performance of insurance. In this article, a Foucaultian approach is employed to problematise the idea of trust and its role in insurance relationships. The case of mis-selling of insurance policies in the United Kingdom since the 1980s, which has given rise to numerous legal rulings, is used as the empirical site for the problematisation. 相似文献

ABSTRACT The implementation of e-government aims at simplifying and improving the relationships and transactions between public administrations and their users or customers. In this vein, the objective of this work is to analyze the factors that promote the development of e-government in the national governments of 192 countries worldwide, differentiating between developed and developing countries. Our findings emphasize that the development of e-government requires that countries have a degree of economic development that enables their citizens to have a certain standard of living, both economic and cultural, as well as important internal government reforms which promote administrative effectiveness. Once these essential factors are fulfilled, the national government's online presence is favored by governments that rule with a majority in their parliaments and with an important fiscal capacity. 相似文献

Belgium is one of the few countries that has been able effectively to accommodate major divisions along linguistic, cultural, ethnic and territorial lines within the fabric of a unitary government. However, one major issue which it has been unable to resolve is the status of its capital city, Brussels, within its devolution reforms. The status of Brussels encapsulates all aspects of the major community divisions in Belgium and has led to numerous unsuccessful legislative proposals, endless parliamentary debates, and the fall of several governments. It was not until 1980 that the Belgian government was able to deal ‘constructively’ with this issue. It did so by removing it from the national political agenda. It is likely that the status of Brussels as a non‐issue is the only resolution possible. 相似文献
