The existence of Roma in youth justice discourses

Critical scholars have repeatedly emphasised the importance of how various categories become constructed. This paper discusses the ‘existence’ of ‘the other’ in youth justice discourses. Drawing on qualitative analysis of police, prosecution, youth court and social services discourses, this paper discusses the positioning of migrant youths, referred to youth court on suspicion of having committed an offence. The talk particularly focuses on Czech and Slovak Roma in two legal departments in Belgium. I discuss in what types of cases and discourses the case of Roma (i.e. references to ethnicity and popular images of the ‘Roma culture’) exists and in what instances it seizes to exist. Particular attention is directed to the constitutions, circularity and contexts of ethnicising discourses throughout youth justice trajectories, as well as their performative nature

Our method extracts patterns of relational and non-relational cues at the frame level and uses them to build a relational graph from which the interactional context at the frame level is estimated via a Graph Convolutional Network based approach. Then it propagates this context over time, together with first-person motion information, through a Gated Recurrent Unit architecture. Ablation studies and experimental evaluation on two publicly available datasets validate the proposed approach and establish state of the art results.Work partially funded by projects MINECO/ERDF RyC, PID2019-110977GA-I00, RED2018-102511-T, and MdM-IP-2019-03Peer ReviewedPostprint (author's final draft

Tacit knowledge and the biological weapons regime

Bioterrorism has become increasingly salient in security discourse in part because of perceived changes in the capacity and geography of life science research. Yet its salience is founded upon a framing of changes in science and security that does not always take into consideration the somewhat slippery concept of ‘tacit knowledge’, something poorly understood, disparately conceptualised and often marginalised in discussions on state and non-state biological weapons programmes. This paper looks at how changes in science and technology—particularly the evolution of information and communications technology—has contributed to the partial erosion of aspects of tacit knowledge and the implications for the biological weapons regime. This paper concludes by arguing that the marginalisation of tacit knowledge weakens our understanding of the difficulties encountered in biological weapons programmes and can result in distorted perceptions of the threat posed by dual-use biotechnology in the 21st century

Ricœur’s Conflict of Interpretations in the Making. Symbols, Reflection and the War of Hermeneutics

The aim of this article is to situate the problem of the conflict of interpretations in Paul Ricœur by placing it in the context of Ricœur’s anthropological reflections on the questions of fallibility and evil. The article invokes the distinction between fallibility and evil and analyses the symbolic language of evil as a reason for the hermeneutic turn of Ricœur’s thought. The implications of this topic for the philosophical analyses of language and consciousness are then put in relief. The article explains the inner workings of the logic of the conflict of interpretations, showing its perspectival trait, and claims that this notion remains pertinent given that its method can today be applied to conflicts of interpretations other than those Ricœur dealt with.Cet article a pour but de situer le problème du conflit des interprétations dans la philosophie de Paul Ricœur. L’article analyse cette notion dans le contexte des réflexions de Ricœur sur la faillibilité et le mal, en faisant la distinction entre ces deux concepts et analysant la manière dont le langage symbolique du mal pousse le tournant herméneutique de Ricœur. Les conséquences du conflit des interprétations pour les analyses philosophiques du langage et de la conscience sont aussi mises en relief. L’article explique la logique du conflit des interprétations, montrant son trait perspectiviste, et argumente que cette notion reste actuelle car sa méthode peut toujours être appliquée à d’autres conflits d’interprétations

Face Clustering for Connection Discovery from Event Images

Social graphs are very useful for many applications, such as recommendations and community detections. However, they are only accessible to big social network operators due to both data availability and privacy concerns. Event images also capture the interactions among the participants, from which social connections can be discovered to form a social graph. Unlike online social graphs, social connections carried by event images can be extracted without user inputs, and hence many social graph-based applications become possible, even without access to online social graphs. This paper proposes a system to discover social connections from event images. By utilizing the social information from even images, such as co-occurrence, a face clustering method is proposed and implemented, and connections can be discovered without the identity of the event participants. By collecting over 40000 faces from over 3000 participants, it is shown that the faces can be well clustered with 80% in F1 score, and social graphs can be constructed. Utilizing offline event images may create a long-term impact on social network analytics.Comment: 18 page
