Quality of evidence assessment of direct and indirect digital biomarkers Hossein, Motahari-Nezhad; Zrubka, Zsombor Csiszarik-Kocsir, Agnes; Popovics, Anett; Feher-Polgar, Pal Wearable, portable, implanted, or ingestible digital devices are used to gather objective, quantifiable, physiological, and behavioral parameters known as digital biomarkers. Meta-analyses of digital biomarkers have increased in recent years, causing the need for evaluating evidence quality. This study evaluated the quality of direct and indirect digital biomarker evidence. Using the definition of digital biomarkers, a search of PubMed and the Cochrane Library was undertaken for articles published in 2019 and 2020. English meta-analyses comparing the clinical effects of therapies using digital biomarkers to those using non-digital biomarker-based interventions were considered. The GRADE technique was used to evaluate the quality of the evidence synthesis in the meta-analyses. The final analysis comprised 26 articles with 95 reported outcomes (26/95, 27.4% direct and 69/95, 72.6% indirect digital biomarkers). There was moderate quality evidence for most indirect digital biomarkers (64/69, 92.8%) and the quality of evidence was low for five outcomes (7.2%). Direct digital biomarkers generated 23.1% (6/26) high-quality evidence and 76.9% (20/26) moderate-quality evidence. Most direct and indirect digital biomarkers provided moderate quality evidence, however, direct biomarkers, because they influence physiological indicators, generate higher evidence.

Project management maturity in a highly innovative and technologically intense context Blaskovics, Bálint; Kádár, Zsombor; Molnár, Máté; Szabó, Lajos; Tóth, János; Tóth, Nikolett Csiszarik-Kocsir, Agnes; Popovics, Anett; Feher-Polgar, Pal Project management maturity can be of utmost importance for companies since their project management process can be improved to a great extent. An effective and efficient project management process can be the key to survival and/or achieving competitive advantage (c.f. Cleland, 1994; Deutsch et al., 2020). Researchers were focusing on identifying the best-suited models (see e.g. Cooke-Davies – Arzymanov, 2003; Kerzner, 2019), but the majority of these models do not consider the specialties and the nature of the different industries. Thus, the aim of this paper is to define a project management maturity approach based on these models, which consider the highly innovative and technologically intense context.

E-document, or the human factor in the security of electronic storage of personal documents Fodor, Nóra; Fehér-Polgár, Pál Csiszarik-Kocsir, Agnes; Popovics, Anett; Feher-Polgar, Pal In today's hectic world, we can often feel that a little help would be nice. The proliferation of smartphones and the invasion of online space into more and more areas of our lives has changed the way we live. There are pros and cons, opportunities and threats. In this article we explore the possibilities of whether an app that stores our personal documents could help us in our daily lives. In this context, we present the present and future possibilities of electronic personal identifiers. We will also carry out a short questionnaire to assess whether our respondents would trust and use a phone app to replace their personal documents. We will also examine the security issues of this use.

Can be the DOSPERT questioner used for mesuring IT risk taking Fehér-Polgár, Pál Csiszarik-Kocsir, Agnes; Popovics, Anett; Feher-Polgar, Pal In a previous study I modified the original DOSPERT questionnaire. And I added a new domain on IT security risk appetite. In a previous publication I presented the results of my surveys with this modified questionnaire. In the present publication, I examine the relationship between the IT security questions in the modified questionnaire and the questions in the other domains of the questionnaire. My hypothesis is that the new questions are not necessary to assess respondents' willingness to take IT security-related risks. I assumed that the answers to the original DOSPERT questions could be used to measure IT security risk appetite in my sample. Statistical tests have disproved this assumption and further investigation is needed.
