Global collaborative networks on meta-analyses of randomized trials published in high impact factor medical journals: a social network analysis
2014
Abstract Background Research collaboration contributes to the advancement of knowledge by exploiting the results of scientific efforts more efficiently, but the global patterns of collaboration on meta-analysis are unknown. The purpose of this research was to describe and characterize the global collaborative patterns in meta-analyses of randomized trials published in high impact factor medical journals over the past three decades. Methods This was a cross-sectional, social network analysis. We searched PubMed for relevant meta-analyses of randomized trials published up to December 2012. We selected meta-analyses (including at least randomized trials as primary evidence source) published in…
Estimating crop primary productivity with Sentinel-2 and Landsat 8 using machine learning methods trained with radiative transfer simulations
2019
Abstract Satellite remote sensing has been widely used in the last decades for agricultural applications, both for assessing vegetation condition and for subsequent yield prediction. Existing remote sensing-based methods to estimate gross primary productivity (GPP), which is an important variable to indicate crop photosynthetic function and stress, typically rely on empirical or semi-empirical approaches, which tend to over-simplify photosynthetic mechanisms. In this work, we take advantage of all parallel developments in mechanistic photosynthesis modeling and satellite data availability for an advanced monitoring of crop productivity. In particular, we combine process-based modeling with …
Facebook’s ad hoc groups: a potential source of communicative power of networked citizens
2017
Ad hoc groups (sporadically formed on social network sites for achieving particular common objectives) have been seen as a public space for citizen participation and debate. This study focuses on Facebook’s ad hoc groups in Finland. The aim is to detect the potential of these groups to enhance networked citizens’ communicative power for raising societally important issues to public agenda and initiate changes in society. We suggest a categorization of the groups according to their missions, and present their members’ specific motivations and objectives through an online survey. Despite the general entertainment-orientation and self-referential nature of social media, the results show that a…
The overstated generational gap in online news use? A consolidated infrastructural perspective
2021
Recent research by Taneja et al. suggested that digital infrastructures diminish the generational gap in news use by counteracting preference structures. We expand on this seminal work by arguing that an infrastructural perspective requires overcoming limitations of highly aggregated web tracking data used in prior research. We analyze the individual browsing histories of two representative samples of German Internet users collected in 2012 ( N = 2970) and 2018 ( N = 2045) and find robust evidence for a smaller generational gap in online news use than commonly assumed. While short news website visits mostly demonstrated infrastructural factors, longer news use episodes were shaped more by …

Uutinen nimeltä viides valtiomahti : suomalaisen sanomalehdistön välittämä kuva Facebookin ad hoc -ryhmistä
2013
William H. Duttonin käsite verkostoituneista kansalaisista viidentenä valtiomahtina löi Suomessa läpi 2010-luvun alussa. Tiedotusvälineissä tämä näkyy kahdella tapaa: ensinnäkin yhä useampi uutisaihe on tavallisten ihmisten esille nostama, toiseksi median toimintaa seurataan entistä tarkemmin. Neljäs valtiomahti on siis saanut oman vahtikoiransa, sosiaalisessa mediassa verkostoituneet ihmiset. Pro gradu -työssäni tarkastelen sanomalehtien välittämää kuvaa sosiaalisen median ad hoc -ryhmistä, jotka ilmentävät viidettä valtiomahtia. Lähden liikkeelle oletuksesta, että tiedolla on merkitystä: sanomalehtien välittämä kuva ad hoc -ryhmistä vaikuttaa siihen, millaisiksi ad hoc -ryhmät mielletään.…
Re-thinking news: Information design and “antibody” contents
2022
Rethinking news and producing quality (“antibody”) contents as a remedy against the rampant proliferation of fake news (and the related erosion of democracy), starting from the values and approaches shared by the worlds of design and journalism can be - and certainly are - an effective and interesting way forward. The fertile confluence of the body of knowledge (and know-how) of these two disciplines has already produced excellent results, starting with design-driven experiments tried and tested in several significant experiences in Italy and abroad. As Paolo Ciuccarelli stated, “once again, designers as ‘meaning makers’ find today in the narrative of the world of the infosphere a design gr…
“Generalist” Journals between Dissemination of Economics and Regime Propaganda
2019
Early in the 20th, generalist journals – a kind of press which had its major diffusion in the nineteenth century – continue to accommodate the contributions of economists offering a specific debating space. However, with the affirmation of fascist ideology, generalist periodicals progressively ceased to exist or to host economists’ articles. Thus, the main object of this research consists in clarifying what could be intended by “generalism” and in relation to which events and ideological pressures it disappeared as a different way to do journalism in a dialectic interplay with specialization. The paper reviews the panorama of generalist journals focusing on the impact of the Fascist regime …
Modes žurnālā Vogue virsrakstu lingvistiskās īpatnības
2017
Mūsdienās, informācijas apmaiņas daudzums ir neizmērojams, līdz ar to, mēdiji ir kļuvuši par mūsu dzīves neatliekamu sastāvdaļu. Pastāv daudz un dažādu žurnālu, laikrakstu, „dzeltenās preses” izdevumu u.t.t., kuros tiek rakstīts par dažādām tēmām.

A bridge over troubled water? Celebrities in journalism connecting implicit and institutional politics
2013
This article looks empirically into how audience members evaluate celebrities in journalism; whether and how celebrities help them to envisage their relationship to politics and media and consequently regard themselves as citizens. The analysis generates a broad and audience-based understanding of celebrities in nine focus group discussions, wherein more than 50 citizens in Finland discussed their favourite celebrities. The discussions revealed three interpretative frames explaining what the celebrities represent to the participants: normative, critical and alternative. In the first two, the groups impose a critical view on celebrities, whereas only the latter one comes close to the optimi…
