Vitalitätseffekte: Erkenntnis und Affekt in der Medienkultur der Zellbiologie

Wie schaffen Bilder Wissen? Welche Rolle kommt der Ästhetik in der naturwissenschaftlichen Bildgebung zu? Was verändert sich an der Beweiskraft des Bildes durch die digitale Bilderzeugung? Die Autorin befasst sich anhand von zellbiologischen Forschungs- und Lehrfilmen mit den bildgebenden Verfahren der computergestützten Mikroskopie. Aus einer medien- und filmwissenschaftlichen sowie kunst- und wissenschaftsgeschichtlichen Perspektive untersucht sie, wie digitale Bilder in der naturwissenschaftlichen Forschung als Erkenntnismedien wirken. Dabei zeigt sich, dass sich die fachlich geschulte, auf Erkenntnisgewinn ausgerichtete Wahrnehmung und die affektive Beteiligung an den Filmen nicht konträr zueinander verhalten, sondern einander bereichern und erweitern

Soundfile. Kultur und Ästhetik einer Hörtechnologie

In the last years the practices of listening to popular music as well as its modes of production and distribution transformed in relation to apps, online services and gadgets. In the article I explore the concept »soundfile“ as an aesthetic and cultural form which correlates with specific practices and techniques of music listening. The dynamics which constitute soundfile listening I describe in four parts: I start with a conceptual description of the plenitude of recorded and produced music which the soundfile listener can access (I. The Standing Reserve of Music). Afterwards I present techniques of combining through which the soundfile listener can select particular pieces of music and connect them with each other (II. Playlists). Therefore I present modulations of the sound of music by the listener as well as by listening technologies (III. Compression and Tuning). Finally I explain selected aspects of the relationship between so-called »social media« and the soundfile listener (IV. Music as »Social« Event). I show in the article that soundfile listening can be defined as follows: Soundfile listening is rather accessing the standing reserve of music which becomes available through the internet than individual collections of music. Soundfile listening is organized rather by playlists than by extensive musical dramaturgies – like they are offered by »concept albums« or »musical masterworks«. Soundfile listening enhances and transforms the sound of music and constitutes technized music listening as a »social« event. In the article I use popular music – a form of music whose development is bound to media technologies – as a subject to make soundfile listening distinguishable at a theoretical and terminological level from other forms of technized listening like record listening or CD listening. -----------------------------URN: urn:nbn:de:hbz:6:3-2013111118

Seroconversion to Seasonal Influenza Viruses after A(H1N1)pdm09 Virus Infection, Quebec, Canada

We looked for cross-reactive antibodies in 122 persons with paired serum samples collected during the 2009 pandemic of influenza virus A(H1N1)pdm09. Eight (12%) of 67 persons with A(H1N1)pdm09 infection confirmed by reverse transcription PCR and/or serology also seroconverted to the seasonal A/Brisbane/59/2007 (H1N1) virus, compared with 1 (2%) of 55 A(H1N1)pdm09-negative persons (p<0.05)

A noticeable difference? Productivity costs related to paid and unpaid work in economic evaluations on expensive drugs

Productivity costs can strongly impact cost-effectiveness outcomes. This study investigated the impact in the context of expensive hospital drugs. This study aimed to: (1) investigate the effect of productivity costs on cost-effectiveness outcomes, (2) determine whether economic evaluations of expensive drugs commonly include productivity costs related to paid and unpaid work, and (3) explore potential reasons for excluding productivity costs from the economic evaluation. We conducted a systematic literature review to identify economic evaluation
