A key challenge for computational psychiatry is to distinguish state from trait markers and go beyond cross-sectional studies. Here we show that as paranoia waxes and wanes in patients with schizophrenia, so too do volatility priors

This is why cities need trees. Hard surfaces and parked cars can reach extreme temperatures, while shaded grass and tree-covered areas stay dramatically cooler. This is the urban heat island effect in one image: hard surfaces absorb and radiate heat, while vegetation and shade reduce it.

So eine Email ist ein kleiner Schritt, aber in Masse kann sie zumindest markieren, dass wir nicht einverstanden damit sind, wenn die hervorragende Arbeit, die hier geleistet wird, im Rauschen verschwindet. Wir brauchen nicht weniger fachlich abgesicherte Information und Debatte, sondern mehr!
Sehr geehrte Damen und Herren!

 

Wie viele Hörer*innen habe ich mit Bestürzung von den geplanten Reformplänen erfahren. Die Einschränkung der Fachmagazine halte ich als Privatperson ebenso wie als Lehrende der Geistes- und Kulturwissenschaften für einen herben Schlag in Richtung der diversen und informierten Informationskultur im deutschsprachigen Raum. Nicht nur innerhalb meiner Familie hören wir regelmäßig mit großem Interesse das Programm aller drei Sender (DLF, DLF Kultur und DLF NOVA) sowie der zahlreichen Podcastangebote, ich empfehle diese auch häufig Studierenden. Da ich Allgemeine und vergleichende Literaturwissenschaft mit kulturwissenschaftlichem Schwerpunkt unterrichte, ist das Programm des Deutschlandradio im Allgemeinen für mich selbst und für meine Studierenden eine unverzichtbare Quelle nicht nur von Nachrichten und Aktuellem, sondern insbesondere mit Blick auf die Fachreportagen ein unverzichtbarer Zugang zu gut recherchierten, verlässlichen Informationen und Einblicken in Bereiche, von denen ich bisher nicht weiß, dass Sie für mich und meine Arbeit von Interesse sind. Kaum absehen kann ich darüber hinaus von den zahlreichen Gesprächen, die sich am (buchstäblichen und metaphorischen ) Küchentisch ergeben, weil wir uns in der Familie über das unterhalten, was im Radio läuft und Erfahrenes weiterbesprechen und weitererzählen. Gerade hier halte ich die gezielte und thematisch nicht nur diverse, sondern auch identifizierbare und auffindbare Programmgestaltung für essenziell, um zu verhindern, dass das hervorragende Programm des Deutschlandradios Teil eines immer weniger differenzierten Hintergrundrauschen der gegenwärtigen Medienlandschaft wird.

 

Ich bitte mit Nachdruck darum – und Presseberichte, wie zahlreiche Initiativen überzeugen mich, dass ich damit nicht allein bin – die Reform in der derzeitig geplanten Weise zu überdenken, um den unverzichtbaren Beitrag des Deutschlandradios zur Kulturlandschaft nicht zu verwässern.
