Purpose Social media posts have been an integral part of our society’s communication and serve purposes from the personal to the national, from the mundane to the silly to the momentous. This study aims to examine social media posts as records, discussing how social media technology serves, perhaps unexpectedly, to reinforce traditional archival understandings of issues such as provenance, custody, access, disposition and preservation. Design/methodology/approach This study follows a four-step methodology. First, this study analyzes literature for a matching definition of the social media record. In the second step, we appraise three social media postings previously curated and cited in news articles by journalists to determine their characteristics – Are these social media posts “records?” Third, this study evaluates the sample records against two dominant theoretical record models, the life cycle and the continuum and attempt to apply the model specifications to the data samples. Finally, this study proposes appropriate records management solutions to address governance issues from the study findings in the conclusion section. Findings This study shows that, even by the most traditional of definitions, social media posts are records. The paper also demonstrates that platform mediation transforms simple narrative documents into records whose provenance, custody and control are dictated by platform logics and governance, outside of the control of their creators. Through appraisal of a small sample of “important” social media posts, this study illustrates that, rather than obsolete, traditional records management concepts and approaches are necessary to ensuring the ongoing accessibility, usability and evidentiary character of social media posts in the broader “platformized” context. Research limitations/implications This is exploratory, theoretical work. In future works, this study plans to expand and validate aspects of this study. Originality/value This paper tests existing theoretical frameworks, namely, the Records Life cycle and the Records Continuum for applicability to the social media record. The paper also offers a view of the potential for traditional archival and records management concepts in service of a just and inclusive recordkeeping, because such concepts allow us to demonstrate the centralized, elite-serving, bureaucratic structures which underpin social media records are obscured by the seemingly decentralized, participatory nature of social media.

The essential oil (EO) of Artemisia plants contains a large number of bioactive compounds that are widely used. The aim of this study was to analyse the chemical composition of EOs of six Artemisia plants collected in Croatia and to test their cholinesterase inhibitory potential. GC–MS analysis of the EO of A. absinthium showed that the dominant compounds are cis-sabinyl acetate and cis-epoxy-ocimene; in EO of A. abrotanum, it is borneol; in the EO of A. annua, they are artemisia ketone, camphor and 1,8-cineole; in the EO of A. arborescens, they are camphor and chamazulene; in the EO of A. verlotiorum, they are cis-thujone, 1,8-cineole and trans-thujone; and in the EO of A. vulgaris, they are trans-thujone and trans-epoxy-ocimene. The EO of the five studied Artemisia species from Croatia is rich in monoterpenoid compounds (1,8-cineole, artemisia ketone, cis-thujone, trans-thujone, cis-epoxy-ocimene, camphor, borneol and cis-sabinyl acetate). The EO of A. arborescens is also rich in chamazulene. The results also showed that the tested EOs have moderate cholinesterase inhibition potential, especially the EOs of A. annua, A. vulgaris and A. abrotanum. This is the first analysis of the chemical composition of the EOs of four Artemisia plants and the first analysis of cholinesterase potential for plants collected in Croatia.

Behçet’s disease is a multisystem disease of insufficiently known etiology, with genetics playing a significant role in its development, featuring an increased frequency of the HLA-B51 gene in the genome of patients, but it can some-times also be associated with the presence of certain strains of bacteria. pathogenetically, this disease is considered to be small-vessel vasculitis. The disease most often manifests itself in oral and genital ulcerations with frequent uveitis and skin changes, and, in very rare cases, there are neurological manifestations, which occur in less than 10 percent of patients that suffer from this disease, and in that case we call it the neuro-Behçet’s disease. The treatment of this disease depends on the clinical condition and the treatment approach is individual for each patient. The greatest challenge is the treatment of neuro-Behçet’s disease due to the severity of the clinical condition and frequent inadequate response to therapy. Neuro-Behçet’s disease is treated with corticosteroids, various immunosuppressants and biological therapy – e.g., TNF-alpha inhibitors as the latest form of therapy with the best results. This paper intends to present the case of a patient with neurological manifestations of the disease, the challenges that we faced during the treatment, the complications that occurred, and the resulting changes in therapy that were sometimes necessary

The use of renewable building materials in construction is crucial to minimising the environmental impact of new buildings. Bio-based building materials have a wide range of positive properties, many of which are due to their hygroscopic behaviour. The purpose of this study is to investigate the hygrothermal performance of chopped straw, sheep’s wool, and cellulose insulated timber frame external wall assemblies in the presence of air leakage and high indoor relative humidity. For this purpose, tests with different moisture contents, overpressures, and defects in the airtight layer were carried out in an outdoor test stand over a period of 18 months. The results were compared with a conventional mineral wool insulated construction. Both sheep’s wool and cellulose are particularly fault-tolerant insulation materials in combination with timber frame constructions. All three bio-based insulations, despite defects in the airtight layer, showed no mould-prone moisture content. An installation level insulated with sheep’s wool can increase the fault tolerance of constructions with insulation made of hygric and more sensitive building materials. For chopped straw and cellulose, the measured U-value was lower than expected. Further in situ measurements of bio-based structures are important to gain confidence in their hygrothermal behaviour and to increase their use in multi-storey construction.

ABSTRACT This paper explores the mobilisation of crisis response and related rhetoric in contemporary European teacher education. Using a critical vertical case analysis of illustrative national, regional, and institutional crisis-mediation settings (Switzerland, Germany, Ireland), we examine how crisis-informed policy response addresses global challenges like teacher shortages and digitalization. Employing an assemblage approach, we foreground how such responses exemplify moves to rethink, remake and redesign teacher education systems and programmes. Our discussions underscore the potential and the problematic aspects of crisis-based policy action to reshape teacher education and emphasize the role of universities and administrative institutions in fostering sustainable change. The study reveals particularly the influence of local contexts and cultures in shaping policy solutions and the dangers of excluding key actors within university teacher education from these conversations and actions. This discussion aims to inspire innovative and culturally-responsive transformations in teacher education practices and policies within Europe, and beyond.

Genetic factors are recognized as risk factors for statin-associated muscle symptoms (SAMS), which are the most common cause of statin intolerance. The aim of this study was to determine whether there is an association between polymorphisms 1236C > T, 2677G > T/A, and 3435C > T in the ABCB1 gene, encoding the efflux transporter of statins, and SAMS, as results on this topic are still controversial. A cross-sectional study was conducted on patients with or without SAMS using atorvastatin. The influence of non-genetic variables on SAMS was also evaluated. Our results show that patients with TT genotype in 1236C > T, 2677G > T/A, and 3435C > T polymorphisms had higher risk of developing SAMS, compared to wild type and heterozygous carriers together (OR 4.292 p  = 0.0093, OR 5.897 p  = 0.0023 and OR 3.547 p  = 0.0122, respectively). Furthermore, TTT/TTT diplotype was also associated with a higher risk of SAMS, OR 9.234 ( p  = 0.0028). Only family history of cardiovascular disease was found to be a risk factor for SAMS, in addition to the known non-genetic variables. We believe that ABCB1 genotyping has great potential to be incorporated into clinical practice to identify high-risk patients in a timely manner.

This research paper aims to assess the sustainable competitiveness of Balkan countries. Sustainable competitiveness was measured based on the indicators in The Sustainable Competitiveness Report from 2022, published by Solability. According to this report, sustainable competitiveness is evaluated using six grouped criteria. In this paper, the competitiveness of the Balkan countries was assessed through the application of the multicriteria analysis methods Entropy and MARCOS (Measurement Alternatives and Ranking according to the Compromise Solution). The weight of each criterion was determined using the Entropy method. The results highlighted that the most significant criteria were Natural Capital and Resource Efficiency & Intensity, which carried the highest weight, whereas the Social Cohesion criterion was of lesser importance, represented by the lowest weight. Using the MARCOS method, the Balkan countries were ranked, with Greece securing the top position, closely followed by Albania, while North Macedonia exhibited the weakest performance. Sensitivity analysis further substantiated these findings. The outcomes of this study significantly contribute to the academic understanding of sustainable competitiveness and provide valuable practical insights for policymakers and stakeholders interested in advancing sustainable development efforts in the Balkan region.

We introduce the theory of high-order harmonic generation by aligned homonuclear diatomic cations using a strong-field approximation. The target cation is represented as a system which consists of two atomic (ionic) centres and one active electron, while the driving field is either a monochromatic or bichromatic field. For a linearly polarised driving field, we investigate the differences between the harmonic spectra obtained with a neutral molecule and the corresponding molecular cation. Due to the larger ionisation potential, the molecular cations can withstand much higher laser-field intensity than the corresponding neutral molecule before the saturation effects become significant. This allows one to produce high-order harmonics with energy in the water-window interval or beyond. Also, the harmonic spectrum provides information about the structure of the highest-occupied molecular orbital. In order to obtain elliptically polarised harmonics, we suggest that an orthogonally polarised two-colour field is employed as a driving field. In this case, we analyse the harmonic ellipticity as a function of the relative orientation of the cation in the laser field. We show that the regions with large harmonic ellipticity in the harmonic energy-orientation angle plane are the broadest for cations whose molecular orbital does not have a nodal plane. Finally, we show that the molecular cations exposed to an orthogonally polarised two-colour field represent an excellent setup for the production of elliptically polarised attosecond pulses with a duration shorter than 100 as.
