From June 28 to July 7 the National Arts Festival took place in Grahamstown, South Africa. For the 20th time Cue, a daily print newspaper about the Festival, was produced by Rhodes University journalism students. It was the first time that the newspaper was printed in full color. Cue is at the core of journalistic production during the Festival. But nowadays, what is a newspaper without pictures or without an online edition? Cue Pix, run by the photo department at the School of Journalism and Media Studies in the AMM (African Media Matrix) provides the pictures. Cue Online is run by the NML (New Media Lab) in the same building and is mostly shoveling print content online. Cue Radio and Cue TV take care of the audio and video, and broadcast during the Festival. Up to 2000 copies of Cue newspaper were printed daily with the number of sold copies around 1600. The newspaper was sold in the Grahamstown streets for 3 Rand. The number of pages of Cue ranges from 16 to 20, including advertisements. Cue is produced by students and lecturers of the School of Journalism and consists of about 50 student-reporters, 10 sub-editors, and 2 editors (who are generally University staff). The productions layout is taken care of by a group of design students. Twenty students from the photo department take care of the pictures and rework them with Adobes Photoshop. Cue TV and Cue Radio (with a total of about 10 students) brought their reporting skills to the Festival as well. Reporting about the Festival by Cue is a major happening that has been growing over the years. From print to TV, to radio and online. This is fantastic, but also reflects equal problems in the media industry: each media platform runs their own show. Print, TV, radio and photography: they all have their own targets, content production, and some coordination. In order to take full advantage of the different possibilities of all the media platforms, convergence is the keyword.

Pressure from politics and the public has created a greater demand for the media to be more accountable. Moreover, growing structural changes in the media landscape – including media concentration, commercialization, fiercer competition, an increasingly fragmented public, and the advent of new media – have also challenged how media should be accountable and responsive. This article looks at how Dutch broadcast media are responding to increasing pressure in terms of accountability and responsiveness through a case-‐study research from two leading broadcast news organizations. The need for more openness to and connection with the public is acknowledged, and among many journalists this is now even considered a necessity. However, when it comes to routinized daily application, there is a general resistance as it does not live within their professional autonomy and authority. New online instruments have created opportunities with more platforms and possibilities for the public to participate. However, at this point the online instruments put new constraints on the social system of organization with unforeseen activities and costs.

This review offers a detailed examination of the current landscape of radio frequency (RF) electromagnetic field (EMF) assessment tools, ranging from spectrum analyzers and broadband field meters to area monitors and custom-built devices. The discussion encompasses both standardized and non-standardized measurement protocols, shedding light on the various methods employed in this domain. Furthermore, the review highlights the prevalent use of mobile apps for characterizing 5G NR radio network data. A growing need for low-cost measurement devices is observed, commonly referred to as “sensors” or “sensor nodes”, that are capable of enduring diverse environmental conditions. These sensors play a crucial role in both microenvironmental surveys and individual exposures, enabling stationary, mobile, and personal exposure assessments based on body-worn sensors, across wider geographical areas. This review revealed a notable need for cost-effective and long-lasting sensors, whether for individual exposure assessments, mobile (vehicle-integrated) measurements, or incorporation into distributed sensor networks. However, there is a lack of comprehensive information on existing custom-developed RF-EMF measurement tools, especially in terms of measuring uncertainty. Additionally, there is a need for real-time, fast-sampling solutions to understand the highly irregular temporal variations EMF distribution in next-generation networks. Given the diversity of tools and methods, a comprehensive comparison is crucial to determine the necessary statistical tools for aggregating the available measurement data.

This study evaluates the maximum theoretical exposure to radiofrequency (RF) electromag- netic fields (EMFs) from a Fifth-generation (5G) New Radio (NR) base station (BS) while using four commonly used mobile applications: YouTube for video streaming, WhatsApp for voice calls, Instagram for posting pictures and videos, and running a Video game. Three factors that might affect exposure, i.e., distance of the measurement positions from the BS, measurement time, and induced traffic, were examined. Exposure was assessed through both instantaneous and time-averaged extrapolated field strengths using the Maximum Power Extrapolation (MPE) method. The former was calculated for every measured SS-RSRP (Secondary Synchronization Reference Signal Received Power) power sample obtained with a sampling resolution of 1 second, whereas the latter was obtained using a 1-min moving average applied on the applications’ instantaneous extrapolated field strengths datasets. Regarding distance, two measurement positions (MPs) were selected: MP1 at 56 meters and MP2 at 170 meters. Next, considering the measurement time, all mobile application tests were initially set to run for 30 minutes at both MPs, whereas the video streaming test (YouTube) was run for an additional 150 minutes to investigate the temporal evolution of field strengths. Considering the traffic, throughput data vs. both instantaneous and time-averaged extrapolated field strengths were observed for all four mobile applications. In addition, at MP1, a 30-minute test without a User Equipment (UE) device was conducted to analyze exposure levels in the absence of induced traffic. The findings indicated that the estimated field strengths for mobile applications varied. It was observed that distance and time had a more significant impact than the volume of data traffic generated (throughput). Notably, the exposure levels in all tests were considerably lower than the public exposure thresholds set by the ICNIRP guidelines.INDEX TERMS 5G NR, C-band, human exposure assessment, mobile applications, traffic data, maximum extrapolation method, RF-EMF.

At this critical moment in time, April 2020, when we are living with the cataclysmic event of Covid-19, television – a medium declared almost dead at the beginning of this millennium – has become a vital resource for solace, daydreaming, social ritual, knowledge and storytelling. In conditions of lockdown, we turn towards television, not away from it (Ellis, 2020; Negra, 2020). We are checking news on national channels, and tuning to live broadcasting for campaigns to help the health services and communities in need, such as with the globally broadcast One World: Together At Home special. We are curling up on the sofa to engage with gripping drama, like Ozark streaming on Netflix, re-watching favourite series from the beginning, such as Buffy or Breaking Bad, and taking part in television quiz shows like Pointless, even watching repeats, to recreate a pub quiz atmosphere in the living room. On a darker note, we are also overloaded with corona news; the ritual evening news bulletin can be a source of anxiety and a cause of sleeplessness. Television infrastructure can break down, from broken satellite dishes to lost remote controls, which are tricky to fix when technicians are not so readily available to help; and television can be an economic burden. The cost of streaming Breaking Bad can push the limits of monthly contracts and data packages. Television both lightens and darkens the mood of domestic spaces and social relations in lockdown culture.

In this work, in situ measurements of the radio frequency electromagnetic field exposure have been conducted for an indoor massive MIMO 5G base station operating at 26–28 GHz. Measurements were performed at six different positions (at distances between 9.94 and 14.32 m from the base station), of which four were in line-of-sight and two were in non-line-of-sight. A comparison was performed between the measurements conducted with an omnidirectional probe and with a horn antenna, for scenarios with and without a user equipment used to actively create an antenna traffic beam from the base station towards the measurement location. A maximum exposure of 171.9 mW/m2 was measured at a distance of 9.94 m from the base station. This is below 2% of the ICNIRP reference level. Moreover, the feasibility to measure the power per resource element of the Synchronization Signal Block - which can be used to extrapolate the maximum exposure level - with a conventional spectrum analyzer was shown by comparison with a network decoder.

Paper presented at Diversity of Journalisms. ECREA Journalism Studies Section and 26th International Conference of Communication (CICOM) The launch of more than 300 free daily newspapers worldwide during the last 15 years defies the idea that newspaper markets are impossible to penetrate. Although a third of papers closed down in the last ten years, newspaper circulation in most countries with free newspapers is actually higher than before their entry. Readership analysis of free newspapers shows that these papers have a younger audience than paid newspapers, contradicting the notion that young people don’t read newspapers anymore.

Regional news media are facing tough times, as they lose readers and advertisers rapidly. In The Netherlands, circulation decreased from 2.7 million in 1990 to 1.8 million in 2010, household penetration declined from 47 percent to 25 percent, and the number of titles went down from 35 to 18 in the same period. We interviewed managers and executives (2009 - 2010) of nine of the eighteen regional newspapers in The Netherlands, to analyse if and how they consider convergence (the transition to an integrated newsroom) a significant option to regain readers and advertisers. This study is part of a research project on the potential (long-term) consequences of convergence for the organizational structure, the work procedures, journalistic quality, and business models of regional news media. Our first results show that convergence is, indeed, embraced as a solution. However, views on how to approach the new market for online news through an integrated newsroom differ significantly. Management tends to operate safely, experimenting with small projects that can be discontinued easily, while editors and journalists on the work floor wish to invest heavily in both the education of employees and technical convergence on a more structural basis. In its examination of how convergence is strategically and operationally changing regional media in The Netherlands this study is the first of its kind.
