The aim of this paper is to present tools that are used by financial institutions to implement legal requirements with regard to anti-money laundering (AML) and combating the financing of terrorism (CFT). The fight against money laundering and terrorist financing is a two-stage procedure, where state authorities outsource a major part of their tasks and responsibilities to private entities. The bulk of the task falls to financial institutions, which have to monitor the transactions of their customers pursuant to international, European and national laws as well as internal policies. To comply with the legal requirements, they use sophisticated surveillance software and collect large amounts of personal data. The European Union introduced two Proposals (COM(2013) 45 final and COM(2013) 44 final) to update the European Union's AML/CFT regime. Even though the Proposals have not yet become legal acts, it is quite obvious that new tools to support financial institutions will emerge. The amendments foreseen by the Proposals as well as already existing tools, which will remain relevant, shall be examined and privacy considerations will be discussed.  相似文献

The optimisation of sales practices in consumer markets through machine learning not only harbours the potential to better match consumer preferences with products, but also risks to facilitate the exploitation of consumer weaknesses discovered via data analysis. More specifically, recent technological advances have brought us to the edge of mind-reading technologies, which automatically analyse mental states and adapt offers accordingly, in potentially manipulative ways. This article shows that, in market contexts, the challenges of manipulation by algorithm necessitate an integrated understanding of unfair commercial practice, data protection, and privacy law. It maps the interactions between these contiguous yet distinct fields of law, and draws on economics and computer science to develop a novel framework to deal with algorithmic influence. Furthermore, it critically discusses the Commission proposals for the Digital Services Act and the Artificial Intelligence Act, and suggests to complement them with more broadly applicable measures to mitigate algorithmic manipulation.  相似文献

How were relationships negotiated across ethnic, racial, and gendered boundaries in the American West in the 1920s and 1930s? Were friendships possible? What limits shaped them? In 1927, four Kiowa students enrolled at Oklahoma University as students of Swedish-born Professor of Fine Arts Oscar B. Jacobson. This article investigates the relationship between Jeanette Berry, wife of one of the Kiowa artists, and Sophie Brousse, Jacobson’s French wife. It focuses on an incident when Berry presented Brousse with a gift of earrings. Placing this gift within a discussion of friendships between strangers illuminates the lines of culture, meaning, and power that separated these women. This relationship had individual ramifications but also formed part of their respective attempts to establish positions and maintain culture within Oklahoma where both American Indians and immigrants faced changing and volatile conditions. Their encounter highlights issues of class as well as ethnicity and culture.  相似文献

Although a bulk of literature shows that perceived social support (PSS) influences academic achievement, the mechanisms through which this effect operates received little empirical attention. The present study examined the multiple mediational effects of motivational beliefs (competence beliefs and subjective value) and emotions (anxiety and enjoyment) that may account for the empirical link between PSS (from parents, peers and teachers) and mathematics achievement. The participants of the study were 238 grade 7 students (average age = 13.2 years, girls = 54%, predominantly native Dutch middle class socioeconomic status). A bootstrap analysis (a relatively new technique for testing multiple mediation) revealed that the motivational beliefs and the emotions, jointly, partially mediated the effect of PSS on achievement. The proportion of the effects mediated, however, varied across the support sources from 55% to 75%. The findings lend support to the theoretical assumptions in the literature that supportive social relationships influence achievement through motivational and affective pathways.  相似文献
