Soziale Medien und Apps in Notsituationen: Eine repräsentative Studie über die Wahrnehmung in Deutschland

Helfer bei Hochwassergefahr mobilisieren oder bei einem Terroranschlag Freunden auf Facebook mitteilen, dass es einem gut geht – immer mehr Menschen nutzen soziale Medien in Notsituationen, Krisen- oder Katastrophenlagen. Schließlich ist es heute kein Geheimnis mehr, dass soziale Medien in jenen Lagen (z. B. überschwemmungen, Stürme, terroristische Anschläge) für diverse Gruppen (z. B. Bürger, Rettungsdienste) von Nutzen sein können. Während Stärken und Schwächen dieser Nutzung bereits eingehend erforscht wurden, widmen sich nur wenige Studien den betreffenden Wahrnehmungen innerhalb der Bevölkerung. Unsere repräsentative Untersuchung von Einstellungen der Bevölkerung in Deutschland gegenüber der Nutzung sozialer Medien in Notsituationen stellt die erste ihrer Art dar. Dabei zeigt sich, dass ungefähr die Hälfte der Befragten (44 %) bereits in Notsituationen zum Zwecke des Teilens und / oder Herausfindens von Informationen auf soziale Medien zurückgegriffen hat. Zudem werden falsche Gerüchte in sozialen Medien mehrheitlich (74 %) als Bedrohung empfunden. Notfall-Apps für das eigene Smartphone werden selten (16 %) heruntergeladen, wobei Wetter- und Erste-Hilfe-Apps am beliebtesten sind

Repeat DNA-PAINT suppresses background and non-specific signals in optical nanoscopy.

Funder: ODNI | Intelligence Community Postdoctoral Research Fellowship Program (IC Postdoctoral Research Fellowship Program); doi: https://doi.org/10.13039/100011040DNA-PAINT is a versatile optical super-resolution technique relying on the transient binding of fluorescent DNA 'imagers' to target epitopes. Its performance in biological samples is often constrained by strong background signals and non-specific binding events, both exacerbated by high imager concentrations. Here we describe Repeat DNA-PAINT, a method that enables a substantial reduction in imager concentration, thus suppressing spurious signals. Additionally, Repeat DNA-PAINT reduces photoinduced target-site loss and can accelerate sampling, all without affecting spatial resolution

Social Media in Emergencies: A Representative Study on Citizens' Perception in Germany

The value of social media in crises, disasters, and emergencies across different events (e.g. floods, storms, terroristic attacks), countries, and for heterogeneous participants (e.g. citizens, emergency services) is now well-attested. Existing work has examined the potentials and weaknesses of its use during specific events. Fewer studies, however, have focused on citizens' perceptions of social media in emergencies, and none have deployed a representative sample to examine this. We present the results of the first representative study on citizens' perception of social media in emergencies that we have conducted in Germany. Our study highlights, for example, that around half (45%) of people have used social media during an emergency to share and / or look for information. In contrast, false rumours on social media (74%) are perceived as a threat. Moreover, only a minority of people have downloaded a smartphone app for emergencies (16%), with the most popular ones' weather and first aid apps

Emergency service staff and social media – A comparative empirical study of the attitude by Emergency Services staff in Europe in 2014 and 2017

Finding a way to ensure an effective use of social media has become increasingly important to emergency services over the past decade. Despite all efforts to determine the utility of social media for emergency organisations, it is necessary to benefit from such institutions' staffs' opinions to establish effective use. To provide empirical evidence we present a comparison of two surveys, conducted across Europe with emergency services in 2014 and 2017 respectively, with a total of 1169 answers. The analysis shows that personal experience has an effect on how organisational usage of social media is perceived and how emergency service staff view the future use of social media. Furthermore, the use has increased. This article not only shows emergency services what their staff think about their social media usage but also discusses challenges and future directions for the design of systems that can be useful for further development of optimized organisational social media usage

Social Media Use in Emergencies of Citizens in the United Kingdom

People use social media in various ways including looking for or sharing information during crises or emergencies (e.g. floods, storms, terrorist attacks). Few studies have focused on European citizens’ perceptions, and just one has deployed a representative sample to examine this. This article presents the results of one of the first representative studies on this topic conducted in the United Kingdom. The study shows that around a third (34%) have used social media during an emergency and that such use is more widespread among younger people. In contrast, the main reasons for not using social media in an emergency include technological concerns and that the trustworthiness of social media content is doubtful. However, there is a growing trend towards increased use. The article deduces and explores implications of these findings, including problems potentially arising with more citizens sharing information on social media during emergencies and expecting a response

Evaluation of Storage Tubes for Combined Analysis of Circulating Nucleic Acids in Liquid Biopsies

In the last decade, circulating nucleic acids such as microRNAs (miRNAs) and cell-free DNA (cfDNA) have become increasingly important in serving as potential novel biomarkers for a variety of human diseases. If cell-free nucleic acids are to become routinely used in diagnostics, the difference in plasma miRNA and cfDNA levels between healthy and diseased subjects must exceed pre-analytical and analytical variability. Until now, few studies have addressed the time limitations of pre-processing or explored the potential use of long-term blood storage tubes, which might need to be implemented in real-life diagnostics. In this study, we analyzed the stability of four breast cancer-associated miRNAs and two cancer-associated genes under various storage conditions, to test their limitations for potential application in clinical diagnostics. In two consecutive experiments, we tested the limits of conventional EDTA tubes, as well as long-term storage blood collection tubes (BCTs) from four different manufacturers. We found that circulating miRNAs are relatively stable when stored in EDTA monovettes for up to 12 h before processing. When stored in BCTs, circulating miRNAs and cfDNA are stable for up to 7 days, depending on the manufacturer. Norgen tubes were superior for cfDNA yield, while Streck tubes performed the worst in our study with hemolysis induction. In conclusion, plasma prepared from whole blood is suitable for the quantification of both cf-miRNAs and cfDNA simultaneously
