Background: Everyday exposure to radiofrequency electromagnetic fields (RF-EMF) emitted from wireless devices such as mobile phones and base stations, radio and television transmitters is ubiquitous. Some people attribute non-specific physical symptoms (NSPS) such as headache and fatigue to exposure to RF-EMF. Most previous laboratory studies or studies that analyzed populations at a group level did not find evidence of an association between RF-EMF exposure and NSPS. Objectives: We explored the association between exposure to RF-EMF in daily life and the occurrence of NSPS in individual self-declared electro hypersensitive persons using body worn exposimeters and electronic diaries. Methods: We selected seven individuals who attributed their NSPS to RF-EMF exposure. The level of and variability in personal RF-EMF exposure and NSPS were determined during a three-week period. Data were analyzed using timeseries analysis in which exposure as measured and recorded in the diary was correlated with NSPS. Results: We found statistically significant correlations between perceived and actual exposure to wireless internet (WiFi - rate of change and number of peaks above threshold) and base stations for mobile telecommunications (GSM+UMTS downlink, rate of change) and NSPS scores in four of the seven participants. In two persons a higher EMF exposure was associated with higher symptom scores, and in two other persons it was associated with lower scores. Remarkably, we found no significant correlations between NSPS and timeweighted average power density, the most commonly used exposure metric. Conclusions: RF-EMFexposure was associated either positively or negatively with NSP Sinsome but not all of the selected self-declared electro hypersensitive persons. https://doi.org/10.1016/j.envint.2018.08.064

Liveblogs are very popular with the public and journalists alike. The problem, though, is their credibility, given the uncertainty of the covered events and the immediacy of their production. Little is known about how journalists routinize the unexpected—to paraphrase Tuchman—when journalists report about an event that is still unfolding. This paper is about makers of liveblogs, livebloggers, so to speak, and the routines and conventions they follow. To better understand the relationship between those who do the “liveblogging” and how the “liveblogging” is done, we interviewed a selection of nine experienced livebloggers who cover breaking news, sports, and politics for the three most-visited news platforms in the Netherlands. Based on our results, we concluded that journalists working at different platforms follow similar routines and conventions for claiming, acquiring, and justifying knowledge. Journalists covering news in liveblogs must have expert knowledge, as well as technical and organizational skills. Liveblogging—in contrast to regular, online reporting—is best summarized as a social process instead of an autonomous production. These findings are important for three reasons: first, to understand how journalists cope with uncertainty covering events under immediate circumstances using liveblogs; second, to understand the workings of this popular format; and third, to contribute to literature about journalistic genres, discourse communities and, more specifically, generic requirements of liveblogs for effects of credibility to take place.

What’s online video today, fifteen years into its exponential growth? In the age of the smart phone, video accompanies, informs, moves, and distracts us. What started off with amateur prosumers on YouTube has spread to virtually all communication apps: say it with moving images. Are you addicted yet? Look into that tiny camera, talk and move the phone, show us around, and prove the others out there that you exist!With this third reader the Video Vortex community — initiated in 2007 by the Instituteof Network Cultures — proves that it is still alive and kicking. No matter its changes, the network is still driven by its original mission to develop a critical vocabulary for this rapidly spreading visual culture: what are the specific characteristics of online video in terms of aesthetics and political economy of image production and distribution, and how do they compare to film and television? Who is the Andre Bazin of the YouTube age? Honestly, why can’t we name a single online video critic? Can we face the fact that hardly anyone is using the internet? What are you going to do with that 4K camera in your smartphone? Have we updated Marshall McLuhan’s hot and cold media for our digital era yet? Who dares? We see the Woman with a Smartphone Camera in action, but who will be our Vertov and lead the avant-garde? Who stops us? Let us radically confront the technological presence as it is and forget the pathetic regression to past formats: radical acceptance of the beautiful mess called the net.
