Revisiting the ‘fallacy of meaningfulness’

In media audience research we tend to assume that media are engaged with when they are used, however ‘light’ such engagement might be. Once ‘passive media use’ was banned as a reference to media use, being a media audience member became synonymous with being a meaning producer. In audience research however I find that media are not always the object of meaning making in daily life and that media texts can be hardly meaningful. Thinking about media and engagement, there is a threefold challenge in relation to audience research. The coming into being of platform media and hence of new forms of media production on a micro level that come out of and are woven into practices of media use, suggests that we need to redraft the repertoire of terms used in audience research (and maybe start calling it something else). Material and immaterial media production, the unpaid labour on the part of otherwise audience members should for instance be taken into account. Then, secondly, there is the continuing challenge to further develop heuristically strong ways of linking media use and meaning making, and most of all to do justice, thirdly, to those moments and ways in which audiences truly engage with media texts without identifying them with those texts.

The parent-child relationship and adolescent alcohol use

BACKGROUNDS:Alcohol use among adolescents has become a major public health problem in the past decade and has large short- and long-term consequences on their health. The aim of this systematic review was to provide an overview of longitudinal cohort studies that have analyzed the association between the parent-child relationship (PCR) and change in alcohol use during adolescence.METHODS: A search of the literature from 1985 to July 2011 was conducted in Medline, PsycINFO, and EMBASE in order to identify longitudinal, general population studies regarding the influence of the PCR on alcohol use during adolescence. The studies were screened, and the quality of the relevant studies was assessed. A best-evidence synthesis was used to summarize the results.RESULTS: Twenty-eight relevant studies were identified. Five studies found that a negative PCR was associated with higher levels of alcohol use. Another seven papers only found this association for certain subgroups such as boys or girls, or a specific age group. The remaining sixteen studies did not find any association.CONCLUSIONS: We found weak evidence for a prospective association between the PCR and adolescent alcohol use. Further research to the association of the PCR with several types of alcohol use (e.g., initiation or abuse) and to the potential reversed causality of the PCR and alcohol use is required.

Conceptualising influencer marketing

Social media has become a prolific tool for companies to build their brands. An effective way to interact with stakeholders on social media has been the relatively new discipline of ‘influencer marketing’. Here, companies engage social media stars to use their large fan-base to promote products and services on their brand’s behalf. While related to the promotional tactic of word-of-mouth marketing, influencer marketing lacks a theoretical foundation in the academic discourse. This paper aims to fill this gap by offering a conceptualisation to operationalize the new discipline in practice. The conceptualisation proposes brand owners a methodology to choose the right influencers for their brands and guides influencers to perform optimally with their fan base. Lastly, a consumer perspective is taken to the discussion to emphasize the relevance of influencer marketing in the consumer purchase decision-making process.

Differences in Ventilation Management and Outcomes between the Two First Waves of the COVID-19 Pandemic—A Comparison between Two Nationwide Observational Studies in The Netherlands

The aim of this analysis was to compare ventilation management and outcomes in invasively ventilated patients with acute hypoxemic respiratory failure due to coronavirus disease 2019 (COVID-19) between the first and second wave in the Netherlands. This is a post hoc analysis of two nationwide observational COVID-19 studies conducted in quick succession. The primary endpoint was ventilation management. Secondary endpoints were tracheostomy use, duration of ventilation, intensive care unit (ICU) and hospital length of stay (LOS), and mortality. We used propensity score matching to control for observed confounding factors. This analysis included 1122 patients from the first and 568 patients from the second wave. Patients in the second wave were sicker, had more comorbidities, and had worse oxygenation parameters. They were ventilated with lower positive end-expiratory pressure and higher fraction inspired oxygen, had a lower oxygen saturation, received neuromuscular blockade more often, and were less often tracheostomized. Duration of ventilation was shorter, but mortality rates were similar. After matching, the fraction of inspired oxygen was lower in the second wave. In patients with acute hypoxemic respiratory failure due to COVID-19, aspects of respiratory care and outcomes rapidly changed over the successive waves.

Blockchain for Organic Food Traceability

From the article: "This article evaluates the application of blockchain technology to improve organic or fair-trade food traceability from “Farm to Fork” in light of European regulations. This study aims to shed light on the challenges in the organic food chain to overcome, the drivers for blockchain technology, and the challenges in current projects."
