Die Medialisierung der Interaktionsordnung und die Ordnung mediatisierter Interaktion. Über digitale Herausforderungen des Goffmenschen

Unter einer medialisierten Interaktionssituation verstehen wir eine medial ‚live‘ oder aufgezeichnet distribuierte Interaktionssituation (mit zwei Anwesenden) oder eine medial (um einen körperlich nicht-anwesenden Dritten) erweiterte Interaktionssituation. Medialisiert wurde und wird die von Goffman in die Diskussion gebrachte Interaktionsordnung also dadurch, dass sie medial ‚übertragen‘ wird, oder dadurch, dass in die von ihm thematisierte face-to-face-Situation durch die neuen mobilen Kommunikationsmittel auch Nicht-Anwesende teilzeitlich oder in Permanenz einbezogen werden. Auch eine medial erweiterte Interaktionssituation ist als solche beendet, wenn der zweite Anwesende ‚weggeht‘, denn dadurch wird die die face-to-face-Situation kennzeichnende Eindrucksfülle zwischen dem verbleibenden Ersten und dem körperlich nicht-anwesenden Dritten auf wechselseitiges kommunikatives Handeln reduziert. Eine medial erweiterte Interaktionssituation erfordert gegenüber der reinen face-to-face-Interaktionssituation eine in verschiedener Hinsicht modifizierte Ordnung.Unter einer mediatisierten Interaktionssituation verstehen wir eine solche, die gegenüber der face-to-face-Interaktion unter Anwesenden entweder grundlegend transformiert ist, oder die überhaupt nur im Rahmen bestimmter kommunikationstechnologisch gegebener Möglichkeiten stattfinden kann. Kommunikationstechnologische Neuerungen ermöglichen permanente Interaktionen zwischen Nicht-Anwesenden. Diese Interaktionen erfordern und befördern Verhaltensregelungen zwischen den Beteiligten, die sich sowohl von den Regelungen der Interaktion zwischen Anwesenden als auch von den Regelungen des sozialen Verkehrs mit ‚langsameren‘ Kommunikationsmitteln unterscheiden. Eine mediatisierte Interaktionssituation ist als solche beendet, wenn der zweite Nicht-Anwesende ‚offline‘ geht. In einer mediatisierten Interaktionssituation muss, damit sie gelingt, die die face-to-face-Situation kennzeichnende Eindrucksfülle unabdingbar ersetzt werden durch eine Fülle von anderen (Arten von) ‚Informationen‘. Eine mediatisierte Interaktionssituation erfordert gegenüber der face-to-face-Interaktionssituation also eine in verschiedener Hinsicht transformierte Ordnung.An geeigneten Beispielen werden wir zeigen, dass der notorisch mit sozialen Situationen konfrontierte Goffmensch sich dergestalt vor neue Herausforderungen gestellt sieht

Geospatial Web Mining for Emergency Management

Emergency management is a domain where information has to be gathered, aggrega ted, and visualized dynamically and quickly. By providing the right information at the right time, the chaos phase between the occurrence of a disaster and the start of well - organized relief measures can be significantly shortened (Paulheim et al. 2009). T he information needed in an emergency scenario can be quite diverse. For example, a person planning an evacuation may need to know about companies that can transport people, and places that can serve as emergency shelters. For the first, bus and taxi compa nies, logistics companies as well as rental car providers may be taken into account. The latter may include hotels and schools as well as sports arenas and concert venues. Although all this information is available on the web, it cannot be easily accessed. Since such non - trivial categories such as buildings that can serve as emergency shelter are not sharply defined, one cannot simply enter emergency shelter into Google and retrieve a list of emergency shelters. Instead, lots of subsequent manual searches h ave to be performed, and the results have to be aggregated by hand. Visual exploration is even more difficult. While several emergency management tools exist (cf. (Paulheim et al. 2009) for a survey), this concern has not been addressed in this context yet. In this paper, we introduce a prototype which allows for a - priori crawling the web for relevant information on objects belonging to non - trivial categories and provide the aggregated results as an OGC compliant web feature service for visual exploration

Diálogos sobre mediatización : una introducción a las investigaciones sobre mediatización en el zemki

Durante la última década, mediatización se convirtió en un concepto central en las investigaciones sobre medios y comunicación. Si bien es posible discernir diferentes enfoques y posiciones en la discusión internacional sobre estos temas, existe una convergencia en la comprensión de que el concepto de mediatización se vincula a una transformación a largo plazo de la cultura y la sociedad, en virtud del carácter cambiante de los medios y la comunicación. Desde esta perspectiva, la mediatización se considera como un "concepto sensibilizador o concientizador" [sensitizing concept] (Blumer, 1954, p. 7; Jensen, 2013, p. 203; Lunt y Livingstone, 2016, p. 464): por un lado, nos sensibiliza en la medida en que, en las sociedades contemporáneas, los medios impregnan diversos dominios; por otro, nos concientiza sobre el hecho de que los medios de comunicación de base tecnológica se han convertido en constitutivos de las prácticas e instituciones que conforman las sociedades contemporáneas. En este sentido, el concepto de mediatización no se refiere a una teoría autónoma, autorreferencial. Más bien, es un término en torno al cual varios investigadores de medios y de la comunicación se unieron para indagar en detalle y analizar críticamente la transformación social y cultural en su relación con los medios.Over the last decade "mediatization" has become a central concept in media and communication research. While different approaches and positions can be discerned in the international discussion, they converge in the understanding that the concept of mediatization is linked to a long-term transformation of culture and society with the changing character of media and communication. From this perspective, "mediatization" is considered as a "sensitizing concept" (Blumer, 1954, p. 7; Jensen, 2013, p. 203; Lunt y Livingstone, 2016, p. 464): On the one hand, it sensitizes us to the extent to which media in contemporary societies permeate their various domains. On the other hand, it sensitizes us to the fact that technologically based communication media have become constitutive for the practices and institutions that make up contemporary societies. In this respect, the concept of mediatization does not refer to a self-contained theory. Rather, it is a term around which various media and communication researchers have come together to investigate in detail and critically analyze social and cultural transformation in relation to media

Mural cell-derived chemokines provide a protective niche to safeguard vascular macrophages and limit chronic inflammation

Maladaptive, non-resolving inflammation contributes to chronic inflammatory diseases such as atheroscle-rosis. Because macrophages remove necrotic cells, defective macrophage programs can promote chronic inflammation with persistent tissue injury. Here, we investigated the mechanisms sustaining vascular mac-rophages. Intravital imaging revealed a spatiotemporal macrophage niche across vascular beds alongside mural cells (MCs)-pericytes and smooth muscle cells. Single-cell transcriptomics, co-culture, and genetic deletion experiments revealed MC-derived expression of the chemokines CCL2 and MIF, which actively pre-served macrophage survival and their homeostatic functions. In atherosclerosis, this positioned macro-phages in viable plaque areas, away from the necrotic core, and maintained a homeostatic macrophage phenotype. Disruption of this MC-macrophage unit via MC-specific deletion of these chemokines triggered detrimental macrophage relocalizing, exacerbated plaque necrosis, inflammation, and atheroprogression. In line, CCL2 inhibition at advanced stages of atherosclerosis showed detrimental effects. This work presents a MC-driven safeguard toward maintaining the homeostatic vascular macrophage niche

From Dyad to Triad: Mediatization and Emerging Risks for Professional Autonomy

With the emergence and spread of digital media, more business models foster and empower client participation in medical professions. With services and products ranging from rating platforms to apps targeting self-diagnosis, these businesses transform the client–practitioner relationship yet risk undermining a central pillar of professions—autonomy. Practitioners have to take legal actions against these business models, making visible the frictional interplay among the involved actors. This development calls for an analytical understanding of how this technology-induced cultural change affects professions and discourses on professionalism. We argue that a perspective on how practitioners deal with these challenges in various situations can be beneficial. Hence, we conceptualize professionals as engaged in identifying, assessing and managing risks for themselves and their clients. The emerging risk-management practices lead to an understanding of how this apparent cultural change plays an increasingly meaningful role for research on how professionalism regarding legitimation of authority is negotiated
