    Abstract The North S\'{a}mi (NS) language encapsulates four primary dialectal variants that are related but that also have differences in their phonology, morphology, and vocabulary. The unique geopolitical location of NS speakers means that in many cases they are bilingual in S\'{a}mi as well as in the dominant state language: Norwegian, Swedish, or Finnish. This enables us to study the NS variants both with respect to the spoken state language and their acoustic characteristics. In this paper, we investigate an extensive set of acoustic features, including MFCCs and prosodic features, as well as state-of-the-art self-supervised representations, namely, XLS-R, WavLM, and HuBERT, for the automatic detection of the four NS variants. In addition, we examine how the majority state language is reflected in the dialects. Our results show that NS dialects are influenced by the state language and that the four dialects are separable, reaching high classification accuracy, especially with the XLS-R model.

    Abstract: ... or treatment-induced change in the oral A. actinomycetemcomitans strain(s) is extremely rare and ... that colonization with the same strain(s) seems to be remarkably persistent. ...

    Abstract Background: The Gram-negative facultatively anaerobic coccobacillus Actinobacillus actinomycetemcomitans is the major pathogen in localized juvenile periodontitis (LJP) and some forms of adult periodontitis (AP). A. actinomycetemcomitans can be grouped into 5 serotypes (a through e) based on differences in the carbohydrate moiety of cell surface lipopolysaccharide. The A. actinomycetemcomitans population is genetically heterogeneous. Since the studies on A. actinomycetemcomitans colonization have mostly applied only culture techniques, the clonality of the follow-up isolates has not been established. Thus, it is possible that, although A. actinomycetemcomitans could be repeatedly isolated from an individual, the initial colonizing strain was replaced by another strain. The aim of the study was to determine whether oral A. actinomycetemcomitans strains change spontaneously over time or after periodontal treatment.
    Methods: A total of 922 A. actinomycetemcomitans isolates were recovered from 115 subjects. From each subject A. actinomycetemcomitans isolates were obtained from 2 to 9 follow-up samples 0.5 to 11.5 years apart. After the first sampling occasion, 99 subjects were treated for either LJP or AP, whereas the 16 non-periodontitis subjects received no treatment. All A. actinomycetemcomitans isolates were serotyped and 235 isolates from 52 subjects genotyped with AP-PCR and/or with ribotyping.
    Results: Isolates of only one serotype, or non-serotypeable isolates alone, were repeatedly found in 104 subjects; serotype a occurred in 25%, b in 33%, c in 23%, d in 5%, e in 7%, and non-serotypeable isolates in 8% of these subjects. Two serotypes (or serotypeable isolates together with non-serotypeable isolates) occurred simultaneously in 9 subjects and in each of these subjects at least one of the serotypes was detected at each sampling occasion. In one subject the initial serotype reappeared although a different serotype was once seen alone, whereas in another subject the initial serotype could not be recovered later. Identical genotypes of A. actinomycetemcomitans were repeatedly detected in each of 52 subjects with follow-up isolates of the same serotype.
    Conclusions: The results showed that spontaneous or treatment-induced change in the oral A. actinomycetemcomitans strain(s) is extremely rare and that colonization with the same strain(s) seems to be remarkably persistent.

    Abstract Incontinence is a common health issue that affects hundreds of millions of people across the world. The solution is often to manage the condition with different kinds of single-use continence technologies, such as incontinence pads and other absorbent hygiene products (AHPs). Throughout their life cycle, these fossil-based products form a remarkable yet inadequately addressed ecological burden in society, contributing to global warming and other environmental degradation. The products are a necessity for their users' wellbeing. When looking for sustainability transitions in this field, focus on individual consumer-choice is thus inadequate - and unfair to the users. The industry is already seeking to decrease its carbon footprint. Yet, to tackle the environmental impact of single-use continence products, also societies and health systems at large must start taking continence seriously. Arguing that continence-aware societies are more sustainable societies, we devise in this article a society-wide working definition for holistically sustainable continence care. Involving dimensions of social, ecological and economic sustainability, the concept draws attention to the wide range of technologies, infrastructures and care practices that emerge around populations' continence needs. Holistically sustainable continence care is thus not only about AHPs. However, in this article, we examine holistically sustainable continence care through the case of AHPs. We review what is known about the environmental impact AHPs, discuss the impact of care practices on aggregate material usage, the future of biobased and degradable incontinence pads, as well as questions of waste management and circular economy. The case of AHPs shows how holistically sustainable continence care is a wider question than technological product development. In the end of the article, we envision an ecosystem where technologies, infrastructures and practices of holistically sustainable continence care can flourish, beyond the focus on singular technologies.

    Abstract Photo-crosslinkable polymers have a great potential for the delivery of sensitive drugs. They allow preparation of drug releasing devices by photo-crosslinking, thus avoiding high processing temperatures. In this study, the hydrolysis behavior and drug release of three different photo-crosslinkable poly(ether anhydride)s and one poly(ester anhydride) were investigated. Three-arm poly(ethylene glycol) or polycaprolactone was reacted with succinic anhydride to obtain carboxylated macromers, and further functionalized with methacrylic anhydride to form methacrylated marcromers with anhydride linkages. The synthetized macromers were used to prepare photo-crosslinked matrices with different hydrolytic degradation times for active agent release purposes. The hydrolysis was clearly pH-sensitive: polymer networks degraded slowly in acidic conditions, and degradation rate increased as the pH shifted towards basic conditions. Drug release was studied with two water-soluble model drugs lidocaine (234 mol/g) and vitamin B

    Abstract Chemotaxonomic biomarkers are needed to monitor and evaluate the nutritional quality of phytoplankton communities. The biomolecules produced by different phytoplankton species do not always follow genetic phylogeny. Therefore, we analyzed fatty acids, sterols, and carotenoids from 57 freshwater phytoplankton strains to evaluate the usability of these biomolecules as chemotaxonomic biomarkers. We found 29 fatty acids, 34 sterols, and 26 carotenoids in our samples. The strains were grouped into cryptomonads, cyanobacteria, diatoms, dinoflagellates, golden algae, green algae, and raphidophytes, and the phytoplankton group explained 61%, 54%, and 89% of the variability of fatty acids, sterols, and carotenoids, respectively. Fatty acid and carotenoid profiles distinguished most phytoplankton groups, but not flawlessly. For example, fatty acids could not distinguish golden algae and cryptomonads, whereas carotenoids did not separate diatoms and golden algae. The sterol composition was heterogeneous but seemed to be useful for distinguishing different genera within a phytoplankton group. The chemotaxonomy biomarkers yielded optimal genetic phylogeny when the fatty acids, sterols, and carotenoids were used together in multivariate statistical analysis. Our results suggest that the accuracy of phytoplankton composition modeling could be enhanced by combining these three biomolecule groups.

    Abstract Electrons from the Earth’s magnetosphere precipitate into the thermosphere and mesosphere at high latitudes as a response to geomagnetic disturbances driven by the solar wind. Energetic electron precipitation (EEP) produces odd nitrogen (NOx) and odd hydrogen (HOx) oxides which catalytically destroy ozone and, thus, locally modulate the radiative and thermal balance. While EEP-HOx is short-living regardless of circumstances, EEP-NOx survives for months in darkness and descends to the polar stratosphere during the winter. Several studies, based on observations and models, have shown that EEP-induced ozone destruction affects the temperature and dynamics in the atmosphere, strengthening the stratospheric polar vortex, a westerly wind system surrounding the pole, in the northern winter hemisphere. Most observational studies on EEP effects, especially those concerning the polar vortex, have relied on reanalysis datasets which are mainly limited to stratospheric altitudes. Thus, observations of EEP effects on the atmosphere are still partly incomplete. In this work we use the AURA/MLS satellite measurements of atmospheric variables and the POES/MEPED satellite measurements of precipitating electrons to study EEP-related interannual variability in chemical and dynamical properties of the mesosphere and stratosphere in the northern winter hemisphere in 2004-2022. In addition to examining the EEP effects in the northern winter stratosphere, we also study the variability of ozone, temperature, and zonal wind in the mesosphere. Satellite observations confirm the earlier found EEP effect on ozone and temperature on the polar vortex, as well as the modulation of the EEP effect on the polar vortex by planetary waves.

    Abstract: ... of teacher’s work during one semester which included integrated Thematic Studies of Sustainable Development ... by the dimensions of sustainable development and learning goals set for teacher’s sustainability competences ...

    Abstract Education for Sustainable Development (ESD) and Entrepreneurial Education (EE) are quite abstract and demanding concepts for teacher students. Yet, Key Sustainability Competences and Entrepreneurial Competences entail important qualities of future citizens and workers, and teacher students should become prepared to accommodate education for these competencies in their teaching practice. This paper explores teacher students’ process of sense-making of sustainable development and how becoming a teacher who practices ESD connects with entrepreneurship. EE serves as a good mirroring surface to ESD as they both have their roots in Transformative Learning (TL) but pursue transformation towards different goals. The case study follows the vocational teacher education (VTE) students’ sensemaking of Sustainable Development as a part of teacher’s work during one semester which included integrated Thematic Studies of Sustainable Development. The qualitative content analysis of students’ texts focused on signs of transformative learning and was guided by the dimensions of sustainable development and learning goals set for teacher’s sustainability competences in the VTE curriculum. The results indicate that transformative learning is possible. Furthermore, they address the importance of certain entrepreneurial capabilities in the actualization of change agency.
