CHORUS Deliverable 2.2: Second report - identification of multi-disciplinary key issues for gap analysis toward EU multimedia search engines roadmap

After addressing the state-of-the-art during the first year of Chorus and establishing the existing landscape in multimedia search engines, we have identified and analyzed gaps within European research effort during our second year. In this period we focused on three directions, notably technological issues, user-centred issues and use-cases and socio- economic and legal aspects. These were assessed by two central studies: firstly, a concerted vision of functional breakdown of generic multimedia search engine, and secondly, a representative use-cases descriptions with the related discussion on requirement for technological challenges. Both studies have been carried out in cooperation and consultation with the community at large through EC concertation meetings (multimedia search engines cluster), several meetings with our Think-Tank, presentations in international conferences, and surveys addressed to EU projects coordinators as well as National initiatives coordinators. Based on the obtained feedback we identified two types of gaps, namely core technological gaps that involve research challenges, and “enablers”, which are not necessarily technical research challenges, but have impact on innovation progress. New socio-economic trends are presented as well as emerging legal challenges

Proceedings of KogWis 2012. 11th Biannual Conference of the German Cognitive Science Society

The German cognitive science conference is an interdisciplinary event where researchers from different disciplines -- mainly from artificial intelligence, cognitive psychology, linguistics, neuroscience, philosophy of mind, and anthropology -- and application areas -- such as eduction, clinical psychology, and human-machine interaction -- bring together different theoretical and methodological perspectives to study the mind. The 11th Biannual Conference of the German Cognitive Science Society took place from September 30 to October 3 2012 at Otto-Friedrich-Universität in Bamberg. The proceedings cover all contributions to this conference, that is, five invited talks, seven invited symposia and two symposia, a satellite symposium, a doctoral symposium, three tutorials, 46 abstracts of talks and 23 poster abstracts

Combined measures of oxygenation, haemodynamics and metabolism to understand neural responses in infants

fNIRS is an established research tool used to investigate typical and atypical brain development.Primarily, it provides measures of haemodynamic changes that are used to indirectly infer neural activity. Broadband NIRS provides a more direct marker of neuronal activation through measurement of changes in cytochrome-c-oxidase (CCO). As a cellular measure, CCO can be used as a bridge to improve our understanding of the link between neural and haemodynamic activity or “neurovascular coupling”. Study 1 demonstrated that changes in mitochondrial activity could be measured alongside haemodynamics during functional activation, over the temporal cortex, using a miniature system in four-to-six-month-old infants. In order to investigate the spatial specificity of CCO, its relation to haemodynamics and to build upon our understanding of neurovascular coupling mechanisms, multi-channel broadband NIRS was used alongside EEG in Study 2 where responses were measured over the visual cortex. Study 2 was performed in adults as the development of a concurrent NIRS and EEG protocol was methodologically challenging. Following this, Study 3 extended on experimental paradigms from Studies 1 and 2 to measure changes in metabolic activity and haemodynamics over the temporal and visual cortices, in four-to-seven-month-old infants. This study demonstrated simultaneous broadband NIRS and EEG use in infants for the first time. The results provided evidence of underdeveloped coupling of cerebral blood flow changes and mitochondrial activity in early infancy. Finally, Study 4 extended the protocol to investigate underlying biological mechanisms that may be altered in neurovascular coupling in autism, by studying infants at high familial risk for the disorder. The findings demonstrated that the combined protocol was not only feasible for use to study atypical brain development but also provided preliminary evidence of altered coupling between cerebral energy metabolism and haemodynamics.Taken together, this work illuminates hitherto undocumented evidence of neurovascular coupling during brain development and highlights the potential of using broadband NIRS with EEG for future neurodevelopmental research in typical and atypical populations

Sources of the communicative body

This study provides evidence for the warranted assertion that classroom practices will be enhanced by awareness of how non-linguistic modalities of the face, hands and vocal intonation contribute to cohesive and cooperative strategies within social groups. Both the history and observations of non-linguistic communication presented by this study suggest that visual, kinesic, and spatial comprehension create and influence social fields and common spaces, yet our language for these fields and spaces is impoverished. This knowledge has been submerged and marginalized through history. At the same time, through time, despite this submersion and marginalization, interrelational and intrarelational synchrony and dis-synchrony, centered on and by the communicative body, occur in social settings in ways that can be considered from both historical and observational perspectives. Buildi ng on recent theory by Damasio, Donald, Noddings, Grumet, Terdiman, and Nussbaum, the historical concepts and classroom observations presented here evidence that social values such as caring, loyalty, and generosity are sometimes understood, implicitly and explicitly, through the exchange, perception, and interpretation of non-linguistic signs. By understanding how the face and hands and rhythm and pitch of the voice create cohesive and cooperative social values in learning spaces - separate from racial, ethnic, and intellectual differences - this investigation recovers a submerged knowledge in order to offer a new logic for understanding social process. In turn, this new logic hopes to further transformational practice in the learning and teaching arts and sciences
