Multiperspective research (MPR) and qualitative longitudinal research (QLR) foreground relationality and temporality, respectively, in qualitative inquiry. Recent efforts to combine these methodologies as multiperspective qualitative longitudinal research (MPQLR) highlight its capacity to examine relational experiences of change over time, yet methodological guidance on how to practically plan and implement MPQLR remains limited. Drawing on our experience of conducting MPQLR studies, this article outlines the key stages of the MPQLR research process. After briefly reviewing existing literature, we present a step-by-step account of research design, data generation, and analysis, emphasizing the methodological challenges and analytic possibilities of integrating relational and temporal perspectives.
The article establishes who must disclose AI-generated content in a museum, when exceptions apply and whether labelling suffices for lawful use of a deceased person’s image and voice.
Methods: Interpretation of the AI Act and polish law, review of deployments.
Results: A museum using an avatar or an AI-generated description is a deployer of an AI system and from 2 August 2026 must label content under Article 50(4). for artistic content, only the form of disclosure changes. A description generated by a language model needs no label if a human genuinely reviewed it and editorial responsibility was assumed.
Discussion and conclusions: Other provisions govern the lawful use of the image and voice. As a rule, disseminating an image requires permission for 20 years after death. later, relatives’ consent is a precaution, not a statutory requirement, regarding the right to the memory of the deceased (kult pamięci).
The CJEU judgment in SCHUFA (C-634/21) redefines the ‘decision’ of Article 22 GDPR: if a score generated by one entity effectively determines another entity’s decision, the data subject is entitled to the protections of Article 22, regardless of whether a human formally signs off. This article asks what that reasoning means for medicine: when an algorithm’s output shapes a physician’s clinical judgment, does the patient have a right to know, and what must they be told? The discussion confronts the SCHUFA doctrine with informed consent requirements under Polish law and the new Article 12 of the Code of Medical Ethics, situates it against the international debate, distinguishes diagnostic from cognitive uses of AI through operational criteria, examines liability for algorithmic harm after Directive (EU) 2024/2853, and addresses the problem of large language models – tools physicians already use but which cannot be meaningfully certified.
Early reviews on social reading platforms are an important clue for book buyers. However, research has so far focused on their volume and average rating rather than their informational content. To address this gap, we scraped nearly one million reviews of 25,000 books across five genres from lubimyczytac.pl, Poland's largest social reading platform. We modeled the long-run accumulation of reviews attracted after a book's 30-day initial launch window. Conditional on early review volume and book characteristics, reviews with greater semantic similarity and stronger solicitation cues predict less subsequent engagement. In contrast, early reviews with more linguistic perplexity and more diverse reviewer portfolios predict more engagement in the future. Furthermore, a text sentiment classifier we fine-tuned to this specific domain added predictive signal beyond the raw star ratings, consistent with ratings being a coarsely discretized projection of the evaluative signal carried by review text. We frame these results within information quality theory: the informational profile of an early review cohort contributes to the prediction of sustained platform engagement beyond review volume and rating.
Law of succession is an area of law that undergoes relatively infrequent changes. Nevertheless, contrary to appearances, significant amendments are also being introduced within it. A great example is the Polish Civil Code of 23 April 1964 and its fourth book, titled “Inheritancesˮ. Over the past thirty years, over ten major and minor amendments have been made. These amendments concerned various aspects of the law of succession, including statutory succession, the form, content, and executors of wills, as well as compulsory share, unworthiness to inherit, and methods of accepting an inheritance. The purpose of this article is to present these changes, and thus the needs, scope and aims of the changes introduced in Polish law of succession since 1990. These amendments should provide an overview of Polish law of succession and its trends over the past thirty years. Finally, the latest draft amendment to the forms of special wills and the scope of changes it provides for will be mentioned.
