While previous studies have documented that toddlers learn less well from passive screens than from live interaction, the rise of interactive, digital screen media opens new perspectives, since some work has shown that toddlers can learn similarly well from a human present via video chat as from live exposure. The present study aimed to disentangle the role of human presence from other aspects of social interactions on learning advantages in contingent screen settings. We assessed 16-month-old toddlers’ fast mapping of novel words from screen in three conditions: in-person , video chat, and virtual agent. All conditions built on the same controlled and scripted interaction. In the in-person condition, toddlers learned two novel word-object associations from an experimenter present in the same room and reacting contingently to infants’ gaze direction. In the video chat condition,tthe toddler saw the experimenter in real time on screen, while the experimenter only had access to the toddler’s real-time gaze position as captured by an eyetracker. This setup allowed contingent reactivity to the toddler’s gaze while controlling for any cues beyond these instructions. The virtual agent condition was programmed to follow the infant's gaze, smile, and name the object with the same parameters as the experimenter in the other conditions. After the learning phase, all toddlers were tested on their word recognition in a looking-while-listening paradigm. Comparisons against chance revealed that toddlers showed above-chance word learning in the in-person group only. Toddlers in the virtual agent group showed significantly worse performance than those in the in-person group, while performance in the video chat group overlapped with the other two groups. These results confirm that in-person interaction leads to best learning outcomes even in the absence of rich social cues They also elucidate that contingency is not sufficient either, and that in order for toddlers to learn from interactive digital media, more cues to social agency are required.

Violence has been a part of daily life in both traditional and digital media. Consequently, neither the existence of violence in the media nor the debates on this subject are new. On the other hand, the presentation of violence in fictional content should be viewed from a different point of view, especially in the context of aesthetization. Within this context, in this chapter, the serial of Penny Dreadful is analyzed. As analyzing method, Tahsin Yücel's model of the “space/time coordinates of narrative” is used. And the subject of “aestheticization of violence” is analyzed through a serial with the elements of person, space, and time. Thus, the role of not only physical beauty but also different components in the aestheticization of violence is examined.

In the socioprofessional as well as the educational context, hybrid communication has experienced an explosion and exerted strong influence not only on our psychic but also on our physical existence. In this context, cybernetics makes it possible to exploit the mechanism of control and interaction among people in continuous motion. With the integration of digital media in all aspects of human life, the exchange of digital data is continuously spreading without neglecting that these new modes of communication and collaboration can also determine our senses as well as our behavior by exerting influence not only on our perceptions and thoughts but also on our mentality. On the other hand, human capacities linked to psychomotor factors make it possible to cultivate critical thinking, sense of responsibility and cooperation. However, the risk of disturbances could lead to a gap of psychomotor investment. Above all, it is necessary to take into account social cognition and the role of memory in online interactions and learning techniques with the uses of computer systems, because the memorization of actual experiences becomes profound, if we perceive each situation in a state of strong emotional involvement.

Technological Impact

This article reflects on the conceptualisation and practise of journalism in European digital native media. The way news is produced and consumed in the digital era knocks down the boundaries that once divided professionals, citizens, and activists. At the same time, significant changes highlighted in recent studies call for a new theoretical and practical approach that goes beyond the dominant perspective of technological determinism. In relation with previous research, we have selected innovative digital media platforms (<em>De Correspondent</em>,<em> Heidi.news</em>, <em>Eldiario.es</em>, <em>IlPost</em>, <em>Mediapart</em>,<em> </em>and <em>Observador</em>), and we have analysed the types of journalism they set out to produce, as gleaned from their public-facing communications and interviews with the platforms’ founders and editors, comparing their stated goals with the journalism they produce and, lastly, we commented on changes in journalism. Digital native media explore renewed fields for journalism. The present analysis allows identifying the emergence of a series of trends in digital native media, which show a coexistence of traditional and new principles. Beyond the technological impact, the new media respond to the needs of society by incorporating the citizen as a reason for its purpose and as a collaborator in production processes. On the other hand, new players and an updated role of journalists come into play with innovative proposals designed for the current multiplatform and mobile scenario.

Unexpected Transformation

Suddenly a new virus has appeared which is threatening society. Fragility, illness and death have become fundamental topics in daily life and social distancing a new form of solidarity. In this unexpected transformation, digital media is playing a crucial role in conveying information about a public sphere that is no longer easily accessible. These changes have also influenced religious communities and their rituals. Through a broad range of selected case studies, this book addresses the complex relationship between religion and the media during the pandemic. On the one hand, it explores processes of (digitally) adapting rituals and messages; on the other hand, it highlights the ambiguous role of religious semantics and practices in addressing the crisis.

Abstract The malignant plasma cells (PC) dependence on the bone marrow (BM) microenvironment is a main feature of multiple myeloma (MM), mainly due to high expression of cell adhesion molecules including CD44, CD54 (ICAM1), CD56, CD49d and chemokines receptors such as CXCR4. At the end stage of the disease, a rare MM complication, that may occurs, is a secondary extramedullary involvement without a leukemic phase and, among the extramedullary localizations, the skin is one of the possible sites, due to the physiological homing of PCs. However, the mechanisms behind the extramedullary spread are not completely understood. In a patient with refractory resistant MM, who has developed a cutaneous localization after 16 months from the diagnosis under Bortezomib (BOR) treatment, we analyzed the gene expression profiles (GEPs) by GeneChip U133 Plus 2.0 (Affymetrix), the immunophenotypic and immunohistochemistry (IHC) profiles of MM cells, across the course of the disease. To confirm the results, IHC profiles on selected molecules were then analyzed in other six MM patients with secondary skin involvement without PC leukemia. On BM CD138+ PCs at diagnosis and BM relapse, by GEP analysis, 742 genes resulted differentially expressed. Moreover, a more stringent analysis identified 19 down-regulated and 42 up-regulated genes; data were confirmed by Real Time PCR on selected genes mainly involved in PC homing. At the BM relapse, we found that MM cells expressed CXCR4 and were negative for CD56; moreover, a significant down-regulation of ICAM1 (CD54) and ALCAM was observed together with the up-regulation of MAGE family genes, DKK1 and SEMA3A in the BM relapse sample compared to diagnosis one. At the cutaneous involvement development, 4 months after BM relapse, by IHC analysis, the MM cells localized in the skin showed the expression of both CD56 and CD54. On the other hand, the BM MM cells immunophenotype confirmed the presence of CD56 but showed the lack of CXCR4 expression. IHC for CD54, CD56 and CXCR4 expression was then performed on both skin and bone biopsies of the other patients analyzed. To go further inside on the role of CXCR4 we treated with BOR (5-10nM) for 24-48h human myeloma cell lines (HMCLs) RPMI-8226 and U266, known to be resistant to BOR, evaluating the CXCR4 expression at both mRNA and protein level, by real-time PCR and by cytofluorimetry, respectively. CXCR4 resulted downregulated after BOR treatment in BOR resistant HMCLs. Consistently, the loss of CXCR4 expression was recently associated to BOR resistance and extramedullary disease in a mouse model of MM suggesting that CXCR4 loss can be correlated with BOR resistance and PCs mobilization from BM, leading to an extramedullary disease. In conclusion, our data indicate that the loss of CXCR4 expression by MM cells across the disease progression, together with CD54 and CD56 down-regulation and their re-acquisition at the extramedullary site, are involved driving the escape of PCs from BM to the extramedullary localization in the skin in the context of Bortezomib resistance.

Flow Coupling

AbstractActive fluid droplets surrounded by oil can spontaneously develop circulatory flows. However, the dynamics of the surrounding oil and their influence on the active fluid remain poorly understood. To investigate interactions between the active fluid and the passive oil across their interface, kinesin-driven microtubule-based active fluid droplets were immersed in oil and compressed into a cylinder-like shape. The droplet geometry supported intradroplet circulatory flows, but the circulation was suppressed when the thickness of the oil layer surrounding the droplet decreased. Experiments with tracers and network structure analyses and continuum models based on the dynamics of self-elongating rods demonstrated that the flow transition resulted from flow coupling across the interface between active fluid and oil, with a millimeter–scale coupling length. In addition, two novel millifluidic devices were developed that could trigger and suppress intradroplet circulatory flows in real time: one by changing the thickness of the surrounding oil layer and the other by locally deforming the droplet. This work highlights the role of interfacial dynamics in the active fluid droplet system and shows that circulatory flows within droplets can be affected by millimeter–scale flow coupling across the interface between the active fluid and the oil.

Teaching and learning in school essentially relies on analogous and digital media, artefacts and tools of all kinds. They are supported and provided by various players. The role of these players for providing learning infrastructures and the interaction between them are discussed in the following paper. Increasingly, Open Educational Resources (OER) become available and the question arises how the interaction between these players is impacted. On the one hand, some players implement closed informational ecosystems that might provide a rich and coherent environment for learning, but also lock the users into a defined and often restricted environment. On the other hand, other players are interested in developing an infrastructure that supports open learning without the boundaries of closed informational ecosystems. Such open informational ecosystems must provide interconnections to numerous, in principal, unlimited number of platforms for learning contents. In the context of the project «Edutags» a reference platform is being implemented by way in which the contents of various providers are being connected and enriched through user-generated tags, commentaries and evaluations. The discussion points out that such an independent reference platform, operated separately from content platforms, must be considered as an important element in an open and truly distributed infrastructure for learning resources. Hence, we do not only need open educational resources to support open learning, we also need to establish an open informational ecosystem that supports such approaches.

Is infants’ word learning boosted by nonhuman social agents? An on-screen virtual agent taught infants word–object associations in a setup where the presence of contingent and referential cues could be manipulated using gaze contingency. In the study, 12-month-old Japanese-learning children (N = 36) looked significantly more to the correct object when it was labeled after exposure to a contingent and referential display versus a noncontingent and nonreferential display. These results show that communicative cues can augment learning even for a nonhuman agent, a finding highly relevant for our understanding of the mechanisms through which the social environment supports language acquisition and for research on the use of interactive screen media.
