ABSTRACT

Online scambaiting problematises the identity of the 419 scammer whose virtual labours connect significantly to the digital dimensions of Afropolitanism. When examined through the photographic practices demanded of 419 scammers in several Internet communities, scambaiting, a form of Internet vigilantism that is targeted at online scammers to avert scam, produces epistemic violence which evacuates the black male body of human dignity. Although scambaiting is potentially an ethical project, it embeds a system of oppression that generates Afropolitan masculinities, caricatured performances of the bodies of 419 scammers exhibited online as objects of shame. As a philosophical and aesthetic response to translocality and mobility, Afropolitanism stresses the cultural experiences and agency of ordinary Africans who assert a global sense of awareness. As both the Afropolitan subject and the 419 scammer are entangled in the assertion of agency, the globalism of both is shown to converge at the intersection of the digital. Building on Lisa Nakamura's essay on dogshaming, I argue that the sexual exploitation of black bodies on scambaiting websites gestures at technology's complicity in interpellating digital subjects and circulating social injustices. Unlike Nakamura, I foreground the performative aspects of scambaiting and connect these to Afropolitanism's intrinsic digitality.  相似文献

This paper explores the cross-national challenges of integrating evidence-based interventions into existing services for high-resource-using children and youth. Using several North American model programme exemplars that have demonstrated efficacy, the paper explores multiple challenges confronting policy-makers, evaluation researchers and practitioners who seek to enhance outcomes for troubled children and youth and improve overall service effectiveness. The paper concludes with practical implications for youth and family professionals, researchers, service agencies and policy–makers, with particular emphasis on possibilities for cross-national collaboration.  相似文献

This article summarizes 8 presentations from Group 8 on the theme “Training of Researchers and Practitioners,” which were part of the 2007 joint symposium of the International Association for Educational and Vocational Guidance, Society for Vocational Psychology, and National Career Development Association held in Padua, Italy. Three themes representing challenges for the profession emerged from the presentations: (a) the need for public policies addressing career development, (b) the need for greater competency standardization, and (c) the need to create innovative training programs. Discussion group participants presented creative strategies for addressing these challenges.  相似文献

A general probabilistically-based approach is proposed for both cancer and noncancer risk/safety assessments. The familiar framework of the original ADI/RfD formulation is used, substituting in the numerator a benchmark dose derived from a hierarchical pharmacokinetic/pharmacodynamic model and in the denominator a unitary uncertainty factor derived from a hierarchical animal/average human/sensitive human model. The empirical probability distributions of the numerator and denominator can be combined to produce an empirical human-equivalent distribution for an animal-derived benchmark dose in external-exposure units.  相似文献

The issue of normalization arises whenever two different values for a vector of unknown parameters imply the identical economic model. A normalization implies not just a rule for selecting which among equivalent points to call the maximum likelihood estimate (MLE), but also governs the topography of the set of points that go into a small-sample confidence interval associated with that MLE. A poor normalization can lead to multimodal distributions, disjoint confidence intervals, and very misleading characterizations of the true statistical uncertainty. This paper introduces an identification principle as a framework upon which a normalization should be imposed, according to which the boundaries of the allowable parameter space should correspond to loci along which the model is locally unidentified. We illustrate these issues with examples taken from mixture models, structural vector autoregressions, and cointegration models.  相似文献

This experiment investigated the impact of the path of approach of an object, from head on versus from the side, and the type of imminent contact with that object, a hit versus a miss, on young infants' perceptions of object looming. Consistent with earlier studies, we found that 4‐ to 5‐month‐old infants do indeed discriminate hits versus misses. We also found a novel result regarding the path of the approaching object. The discrimination of hits from misses was modified by whether or not the approaching objects passed in front of the infants' faces; objects crossing the line of sight evoked more frequent defensive reactions than objects that did not cross the line of sight, regardless of whether or not such objects were on a collision course. These findings are discussed within the context of the development of visually guided locomotion and linear versus nonlinear paths of translation through the world.  相似文献

This paper reviews the scholarly literature that connects transnational crime and policing through a critical discussion of the terms used to describe them. It is argued that authorized discourses regarding transnational crime are selective and partial. Ultimately, this results in two sorts of failures in contemporary transnational policing. It is a positive failure insofar as the ramping up of policing power in response to a global crime panic has come at the expense of civil liberties and human rights. It is a negative failure insofar as the transnational policing capacity that has been developed is unable to respond to the very real criminological consequences that are part of the downside of globalization. The surveillant assemblage of the emerging global policing security complex is an awesome and unaccountable power legitimitated on the basis of specified folkdevils. However, and despite well-publicized claims to success, due to its own internal organizational pathologies and institutional fragmentation, the policing security complex is capricious. The article concludes by arguing that critical the examination of the concepts that constitute transnational crime and policing is a crucial contribution to theories of global governance.  相似文献
