BackgroundEuropean health care systems regard information and communication technology as a necessity in supporting future health care provision by community home care services to home-dwelling older adults. Communication technology enabling synchronous communication between 2 or more human actors at a distance constitutes a significant component of this ambition, but few reviews have synthesized research relating to this particular type of technology. As evaluations of information and communication technology in health care services favor measurements of effectiveness over the experiences and dynamics of putting these technologies into use, the nuances involved in technology implementation processes are often omitted. ObjectiveThis review aims to systematically identify and synthesize qualitative findings on the uses and experiences of synchronous communication technology for home-dwelling older adults in a home care services context. MethodsThe review follows the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020 checklist for reporting. We conducted a cross-disciplinary search in 5 databases for papers published between 2011 and 2023 that yielded 4210 citations. A total of 13 studies were included after 4 screening phases and a subsequent appraisal of methodological quality guided by the Critical Appraisal Skills Programme tool. From these, prespecified data were extracted and incorporated in a 3-stage thematic synthesis producing 4 analytical themes. ResultsThe first theme presented the multiple trajectories that older users’ technology acceptance could take, namely straightforward, gradual, partial, and resistance laden, notwithstanding outright rejection. It also emphasized both instrumental and emotional efforts by the older adults’ relatives in facilitating acceptance. Moving beyond acceptance, the second theme foregrounded the different types of work involved in attempts to integrate the technology by older users, their relatives, and health care providers. Theme 3 highlighted how the older users’ physical and cognitive conditions formed a contextual backdrop challenging this integration work, together with challenges related to spatial context. Finally, consequences derived from taking the technology into use could be of a both enabling and complicating nature as integration reconfigured the way users related to themselves and each other. ConclusionsThe acceptance and integration of synchronous communication technology for older adults involves multiple user groups in work tending to the technology, to the users themselves, and to each other through intergroup negotiations. This review’s original contribution consists of its attention to the dynamics across different user groups in deriving consequences from using the technology in question, in addition to its assertion that such consequences may be both intentional and unintentional. We argue that our findings may be used to provide nuance to policies addressing—and practices taking place in—contexts that involve similar user technology constellations to the ones explored in this paper.

This article contributes to the sociology of education and technology by providing a cultural analysis of scepticism towards new technologies in school, using reactions to the telepresence robot 'AV1' as its case. AV1 is designed to connect 'homebound' students with their 'school-based' teachers and classmates. Despite its idealistic purpose, the robot has been met with significant scepticism by Norwegian school workers. To understand why, the article proposes the novel concepts of 'educational purity' and 'technological danger' to highlight the shared beliefs that underlie school workers' concerns. We find that school workers see AV1 as threatening key ideals of schools being pedagogically oriented, physically copresent and bounded institutions -- all concerns that reflect widespread ideas about how technologies tend to (not) function within educational contexts. In highlighting these symbolic tensions between new technologies and schools, the article sets a course for future studies into the cultural sociology of education and technology.

'Homebound' children are unable to attend school for illness-related reasons. To lessen their predicament, schools have begun experimenting with 'telepresence robots' that can enable remote participation. While promising, we know little about the use of telepresence robots in practice. To begin to redress this, we draw on 159 semi-structured interviews to explore the experiences of 37 child users of the robot 'AV1' in Norwegian schools. The children's experiences varied, with some benefitting greatly and others not getting any benefit from using the robot. To explain these variations, we reconstruct the robot's "critical component structure" -- that is, the assembly of sociomaterial elements that determines whether and how the robot works in practice. We also explore the benefits of using the robot when these critical components align. In so doing, we provide in-depth knowledge about the potential and prerequisites of using telepresence robots in schools -- to the benefit of users, producers and scholars of telepresence technology.

The overall aim of this scoping review is to present empirical studies regarding how the Nordic model has been investigated in relation to management in international companies. The subse quent objective is to discuss the model’s robustness regarding internationalization. The question raised is how the Nordic model, in relation to management, is configured in empirical studies undertaken in international corporations. Using systematic literature searches to examine peer- reviewed articles published between 2000 and 2022, 15 out of 972 studies were eligible for a full review. Primarily, one facet of the model was investigated: workplace democracy. Foreign-owned companies operating in Nordic countries partly adopted the model, whereas the model was implemented to some extent in Nordic-owned companies abroad. Management’s support and employee involvement were considered important. This review indicates that there is pressure on the model, although it has extended beyond the Nordic border and appears to be adaptable to global working life.

Artikkelens hensikt er å bidra til økt innsikt i faktorer som har betydning for at barnehagen skal fungere som læringsarena for studenter ved arbeidsplassbasert barnehagelærerutdanning (ABLU). ABLU-studenter arbeider i barnehage parallelt med studiene. Gjennom utdanningsløpet opplever de kontinuerlige grensekryssinger mellom å være student og assistent, samt en grensekryssing fra assistent til barnehagelærerrollen. Resultatene baseres på kvalitative data fra fokusgruppeintervju. Problemstillingen er: Hvordan kan barnehagen være en støttende læringsarena i ABLU-studenters grensekryssinger? Funnene viser til utfordringer studentene møter underveis i grensekryssingene, primært knyttet til å synliggjøre og bruke fagkunnskapen sin på egen arbeidsplass under utdanningsløpet. Støtte og forventningsavklaringer fremtrer som nødvendige faktorer for at barnehagen skal fungere optimalt som læringsarena når studentene utvikler profesjonsidentitet og krysser grenser mellom ulike praksisfellesskap i praksislandskapet. ENGLISH ABSTRACT “I feel like I’m somewhere in between.” Crossing boundaries in workplace-based early childhood teacher education This article aims to investigate factors regarding learning environment for students in Workplace-Based Early Childhood Teacher Education (ABLU). ABLU students are working in kindergarten simultaneously with their studies. Throughout the educational process, they continuously experience the shifts between being a student and a kindergarten assistant in the same community of practice, as well as the shift from being an assistant to being a kindergarten teacher. The results are based on qualitative data from focus group interviews. The topic in question is: How can the kindergarten as a learning environment be of support in ABLU students’ border crossing between different roles in kindergarten settings? The findings refer to challenges the students encounter during these changes of roles, primarily related to the opportunities to make their professional knowledge visible and applicable in their own workplace during their education. There appear to be two necessary factors for kindergarten to function optimally as a learning environment when the students develop a professional identity and cross boundaries between roles. These two factors are support and clarification of expectations.

Nervous systems are endowed with rapid chemosensation and intercellular signaling by ligand-gated ion channels (LGICs). While a complex, bilaterally symmetrical nervous system is a major innovation of bilaterian animals, the employment of specific LGICs during early bilaterian evolution is poorly understood. We therefore questioned bilaterian animals’ employment of acid-sensing ion channels (ASICs), LGICs that mediate fast excitatory responses to decreases in extracellular pH in vertebrate neurons. Our phylogenetic analysis identified an earlier emergence of ASICs from the overarching DEG/ENaC (degenerin/epithelial sodium channel) superfamily than previously thought and suggests that ASICs were a bilaterian innovation. Our broad examination of ASIC gene expression and biophysical function in each major bilaterian lineage of Xenacoelomorpha, Protostomia, and Deuterostomia suggests that the earliest bilaterian ASICs were probably expressed in the periphery, before being incorporated into the brain as it emerged independently in certain deuterostomes and xenacoelomorphs. The loss of certain peripheral cells from Ecdysozoa after they separated from other protostomes likely explains their loss of ASICs, and thus the absence of ASICs from model organisms Drosophila and Caenorhabditis elegans. Thus, our use of diverse bilaterians in the investigation of LGIC expression and function offers a unique hypothesis on the employment of LGICs in early bilaterian evolution.

Vestfjorden in northern Norway, a major spawning ground for the northeast Arctic cod, is sheltered from the continental shelf and open ocean by the Lofoten–Vesterålen archipelago. The archipelago, however, is well known for hosting strong and vigorous tidal currents in its many straits, currents that can produce significant time-mean tracer transport from Vestfjorden to the shelf outside. We use a purely tidally driven unstructured-grid ocean model to look into non-linear tidal dynamics and the associated tracer transport through the archipelago. Of particular interest are two processes: tidal pumping through the straits and tidal rectification around islands. The most prominent tracer transport is caused by tidal pumping through the short and strongly non-linear straits Nordlandsflaget and Moskstraumen near the southern tip of the archipelago. Here, tracers from Vestfjorden are transported tens of kilometers westward out on the outer shelf. Further north, weaker yet notable tidal pumping also takes place through the longer straits Nappstraumen and Gimsøystraumen. The other main transport route out of Vestfjorden is south of the island of Røst. Here, the transport is primarily due to tracer advection by rectified anticyclonic currents around the island. There is also an anticyclonic circulation cell around the island group Mosken–Værøy, and both cells have flow speeds up to 0.2 m s−1, magnitudes similar to the observed background currents in the region. These high-resolution simulations thus emphasize the importance of non-linear tidal dynamics for transport of floating particles, like cod eggs and larvae, in the region.

Abstract Background Toll-like receptors (TLRs) play a crucial role in immunity and development. They contain leucine-rich repeat domains, one transmembrane domain, and one Toll/IL-1 receptor domain. TLRs have been classified into V-type/scc and P-type/mcc TLRs, based on differences in the leucine-rich repeat domain region. Although TLRs are widespread in animals, detailed phylogenetic studies of this gene family are lacking. Here we aim to uncover TLR evolution by conducting a survey and a phylogenetic analysis in species across Bilateria. To discriminate between their role in development and immunity we furthermore analyzed stage-specific transcriptomes of the ecdysozoans Priapulus caudatus and Hypsibius exemplaris, and the spiralians Crassostrea gigas and Terebratalia transversa. Results We detected a low number of TLRs in ecdysozoan species, and multiple independent radiations within the Spiralia. V-type/scc and P-type/mcc type-receptors are present in cnidarians, protostomes and deuterostomes, and therefore they emerged early in TLR evolution, followed by a loss in xenacoelomorphs. Our phylogenetic analysis shows that TLRs cluster into three major clades: clade α is present in cnidarians, ecdysozoans, and spiralians; clade β in deuterostomes, ecdysozoans, and spiralians; and clade γ is only found in spiralians. Our stage-specific transcriptome and in situ hybridization analyses show that TLRs are expressed during development in all species analyzed, which indicates a broad role of TLRs during animal development. Conclusions Our findings suggest that a clade α TLR gene (TLR-Ca) and a clade β/γ TLR gene (TLR-Cβ/γ) were already present in the cnidarian-bilaterian common ancestor. However, although TLR-Ca was conserved in cnidarians, TLR-Cβ/γ was lost during the early evolution of these taxa. Moreover, TLR-Cβ/γ duplicated to generate TLR-Cβ and TLR-Cγ in the lineage to the last common protostome-deuterostome ancestor. TLR-Ca, TLR-Cβ and TLR-Cγ further expanded generating the three major TLR clades. While all three clades radiated in several spiralian lineages, specific TLRs clades have been presumably lost in other lineages. Furthermore, the expression of the majority of these genes during protostome ontogeny suggests a likely role in development.

We investigate the formation and evolution of dipole vortices and their contribution to water exchange through idealized tidal straits. Self-propagating dipoles are important for transporting and exchanging water properties through straits and inlets in coastal regions. In order to obtain a robust dataset to evaluate flow separation, dipole formation and evolution, and the effect on water exchange, we conduct 164 numerical simulations, varying the width and length of the straits as well as the tidal forcing. We show that dipoles form and start propagating at the time of flow separation, and their vorticity originates in the velocity front formed by the separation. We find that the dipole propagation velocity is proportional to the tidal velocity amplitude and twice as large as the dipole velocity derived for a dipole consisting of two point vortices. We analyze the processes creating a net water exchange through the straits and derive a kinematic model dependent on dimensionless parameters representing strait length, dipole travel distance, and dipole size. The net tracer transport resulting from the kinematic model agrees closely with the numerical simulations and provides an understanding of the processes controlling net water exchange.

Abstract Background The brain anatomy in the clade Spiralia can vary from simple, commissural brains (e.g., gastrotrichs, rotifers) to rather complex, partitioned structures (e.g., in cephalopods and annelids). How often and in which lineages complex brains evolved still remains unclear. Nemerteans are a clade of worm-like spiralians, which possess a complex central nervous system (CNS) with a prominent brain, and elaborated chemosensory and neuroglandular cerebral organs, which have been previously suggested as homologs to the annelid mushroom bodies. To understand the developmental and evolutionary origins of the complex brain in nemerteans and spiralians in general, we investigated details of the neuroanatomy and gene expression in the brain and cerebral organs of the juveniles of nemertean Lineus ruber. Results In the juveniles, the CNS is already composed of all major elements present in the adults, including the brain, paired longitudinal lateral nerve cords, and an unpaired dorsal nerve cord, which suggests that further neural development is mostly related with increase in the size but not in complexity. The ultrastructure of the juvenile cerebral organ revealed that it is composed of several distinct cell types present also in the adults. The 12 transcription factors commonly used as brain cell type markers in bilaterians show region-specific expression in the nemertean brain and divide the entire organ into several molecularly distinct areas, partially overlapping with the morphological compartments. Additionally, several of the mushroom body-specific genes are expressed in the developing cerebral organs. Conclusions The dissimilar expression of molecular brain markers between L. ruber and the annelid Platynereis dumerilii indicates that the complex brains present in those two species evolved convergently by independent expansions of non-homologous regions of a simpler brain present in their last common ancestor. Although the same genes are expressed in mushroom bodies and cerebral organs, their spatial expression within organs shows apparent differences between annelids and nemerteans, indicating convergent recruitment of the same genes into patterning of non-homologous organs or hint toward a more complicated evolutionary process, in which conserved and novel cell types contribute to the non-homologous structures.

Abstract Background European canker, caused by Neonectria ditissima, is a disease of worldwide importance in apple production, yet knowledge about it is limited, highly regional and sometimes contradictory. This is an obstacle to successful disease management. Key aspects for Northern Europe are reviewed, based on research results from Northern Germany and Norway and on international literature data. Main topics Trunk cankers developing on young trees within the first 1–3 seasons of explanting can often be traced back to latent infections initiated in the nurseries. The most important nursery infection is a lateral canker on the main trunk of ‘knip’ trees, which are the standard tree type in Northern Europe. In strongly affected batches, up to 25% of trees have to be uprooted after the first growing season due to such trunk cankers. The establishment and maintenance of healthy orchards requires clean nursery material, especially in the case of susceptible cultivars. In Northern Germany, infections within commercial orchards most often proceed through wounds caused by fruit picking or leaf fall in autumn, as shown by the appearance of cankers in the following spring and by the high efficacy of fungicide treatments at leaf fall. Ascospores, commonly thought to be relevant for long-distance spread of infections, are not released until the end of leaf fall even in wet autumn seasons in Northern Germany. Therefore, their role in the disease remains unclear. Strong nitrogen-induced vegetative growth favours apple canker. In field trials conducted under conditions of current commercial practices, autumnal sprays with copper hydroxide or copper oxide were consistently more efficacious than copper oxychloride or captan in preventing new infections. Conclusions Restricted fertilisation and other measures to curb excessive vegetative growth during the first few years of an orchard, repeated canker pruning and well-timed treatments with effective fungicides in autumn are essential for IPM of apple canker. Nonetheless, canker remains capable of severely impairing the commercial success of susceptible cultivars in regions with wet climates even if all available measures are taken. This opens up long-term perspectives for the breeding of more resistant cultivars.

Sammendrag Artikkelen undersøker hvordan ensomhet blant eldre er forsøkt motvirket ved bruk av digital teknologi: Kommunikasjonsløsningen Komp er en skjerm med kun én knapp og en tilhørende app man kan bruke til å sende bilder, meldinger og opprette videosamtaler med skjermen. Den er utviklet spesielt for eldre brukere uten digital kompetanse og skal motvirke ensomhet gjennom økt digital sosial kontakt. Utviklerne kaller den en «varm teknologi» fordi de mener den knytter folk sammen. Vi bruker skriptteori til å undersøke samspillet mellom teknologiens utforming, brukernes erfaringer og sentrale normer i demokratiske samfunn. Analysen viser at Komp kommer med «innskrevne» forventninger om velfungerende familier med digitalt inkompetente eldre og kompetente pårørende. Når brukerne godtok forventningene, uten videre eller gjennom tilpasning, fikk Komp være en varm teknologi og skape digitalt mediert familienærvær. Men det kunne også oppstå friksjon, enten fordi brukerne avviste forventningene, eller fordi teknologien aktualiserte motsetningsfylte normer knyttet til medborgerskap og selvbestemmelse på den ene siden, og omsorg og myndighetsoverføring på den andre. Artikkelen bidrar til å forstå de sosiomaterielle forutsetningene for at digitale teknologier kan bringe folk sammen og derigjennom redusere ensomhet.

This paper explores a translation process of Nordic workplace democracy by using an empirical case study of a Norwegian company setting up a subsidiary company in the US. The paper con- tributes to existing accounts of how ideas and practices in international companies are translated from one institutional context to another by focusing on the role of agency in translation processes. Drawing on advances in Scandinavian institutional theory, the findings show how employees from the source context acted as skilled translators in the new local context and helped to close the skills-gap between employees with and without experience of workplace democracy. In addition, the US managers had work experience from the company in Norway as well as from the US. The employees’ and managers’ complementary contextual knowledge represented important institutional bridging skills in the process of reproducing workplace democracy in the new local setting. However, during the translation process, some of the elements in the workplace democracy model were discussed and modified. This demonstrates how the organizations’ approach can change over time, from a reproducing to a modifying mode.

Bacterial canker, caused by Pseudomonas syringae pv. syringae and pv. morsprunorum, is one of the most important diseases of stone fruit trees (Prunus spp.). The pathogen infects buds, flowers, fruitlets, leaves and shoots, from which the disease spreads to the branches, boughs and trunks, causing necrosis and cankers. The efficacy of different chemical and biological products for the control of bacterial canker on stone fruit trees was tested in 2018–2021. The experiments were conducted in sour cherry, plum and sweet cherry orchards in central Poland. Foliar application of the tested preparations was performed three times a season. The biological efficacy of the tested products in the control of bacterial canker was evaluated on sour cherry on the basis of infected leaves and fruits and on plum and sweet cherry on the basis of infected leaves. The highest efficacy was observed for products containing various forms of copper—copper oxide, copper oxychloride and copper hydroxide—as well as fertilizers with copper gluconate and the fungicide Luna Care 71.6 WG (fluopyram and fosetyl-Al). However, the biological preparations were significantly less effective. The conducted studies showed that preparations based on copper gluconate can be a valuable alternative to typical copper fungicides.

Introduction Most research on loneliness comes from the health sciences, statistically seeking to measure the health-related effects of feeling alone or isolated. There is a need to expand on this understanding and explore loneliness as a more complex social phenomenon. In this article, we present a qualitative design for studying the intersection between loneliness, technology and culture. Conceptualising this as the cultural dialectic between loneliness and technology, we aim to unpack the reciprocal ways by which understandings of loneliness shape technology, while technologies also affect society’s understandings of loneliness. In elucidating this dialectic, we aim to develop new knowledge and a novel theoretical framework for understanding loneliness and its technological solutions, which, in turn, can enable better solutions to contemporary problems of loneliness.Methods and analysis We will adopt a qualitative approach that combines interviews, participant observation and textual analysis to explore loneliness and its technological solutions from the perspectives of policy-makers, producers, professionals and users in Norway and the UK. The data will be analysed through an analytical framework combining insights from discourse theory and philosophical debates on presence, which will allow us to capture and rethink fundamental assumptions about loneliness and technology. Outcomes will be revised understandings of loneliness, relevant to researchers, entrepreneurs, policy-makers, clinicians, educators and the broader public.Ethics and dissemination The project has been evaluated and approved by the data protection officer at Oslo Metropolitan University and by the Norwegian Social Science Data Services. Additional ethical approval for data collection in the UK has been provided by the University of Oxford Interdivisional Research Ethics Committee. Informed consent will be obtained from all participants. Findings will be disseminated through peer-reviewed publications, international conference presentations and lay media.

Artikkelens hensikt er å bidra til økt innsikt i hvordan veiledning på egen arbeidsplass erfares av studenter på arbeidsplassbasert barnehagelærerutdanning. Barnehagen er en viktig læringsarena i studietiden, og veiledning i egen barnehage skal støtte studentenes læringsprosess. Resultatene er basert på kvalitative data fra fokusgruppeintervju, og viser at studentene opplever veiledning som et betydningsfullt bidrag til egen læring. Imidlertid finner vi store variasjoner i organisering, og at rolleavklaring mellom studenter og veiledere har vært et lite artikulert tema. Spesielt synes fraværet av rolleavklaring i overgangen til studentrollen å skape utfordringer for studenten.

This article focuses on the impact of the physical environment and construction of play culture in kindergartens. Based on a case study, we explore employees' perception of indoor physical environment and children's play. The findings revealed that gender is interwoven in the physical environments and materials. Children's play practices are associated with gender and perceived as setting different requirements for physical design. These play practices are anchored to different rooms and create a connection between rooms, zones, and gender. In additional, play practices produce and reproduce the employees' ideas of gender. The physical environment has a structural power on children's play practices. The impact of the environment on the construction of play practices makes visible the importance of reflecting on the construction of the indoor environment and gender meaning in order to contribute to using the kindergarten in an equal manner.

Abstract Background Medically unexplained symptoms (MUS) are a common yet challenging encounter in primary care. The aim of this study was to explore how general practitioners (GPs) understand and handle MUS. Methods Three focus group interviews were conducted with a total of 23 GPs. Participants with varied clinical experience were purposively recruited. The data were analysed thematically, using the concept of framing as an analytical lens. Results The GPs alternated between a biomedical frame, centred on disease, and a biopsychosocial frame, centred on the sick person. Each frame shaped the GPs’ understanding and handling of MUS. The biomedical frame emphasised the lack of objective evidence, problematized subjective patient testimony, and manifested feelings of uncertainty, doubt and powerlessness. This in turn complicated patient handling. In contrast, the biopsychosocial frame emphasised clinical experience, turned patient testimony into a valuable source of information, and manifested feelings of confidence and competence. This in turn made them feel empowered. The GPs with the least experience relied more on the biomedical frame, whereas their more seasoned seniors relied mostly on the biopsychosocial frame. Conclusion The biopsychosocial frame helps GPs to understand and handle MUS better than the biomedical frame does. Medical students should spend more time learning biopsychosocial medicine, and to integrate the clinical knowledge of their peers with their own.

This article examines the impact on work culture when men work in kindergartens. In Norway, as in other countries there has been a call for more male staff in kindergartens. Increasing the amount of men may imply that institutionalized norms and practice are put under pressure. By using a case study approach, the focus is on employees' experiences and practice in daily life in the kindergarten. Two processes, negotiation about work organization and the division of labour, illustrate the empirical part of this article. The findings indicate that female staff negotiate for standardized workdays and norms of sameness, while the males negotiate for a flexible workday and division of labour based on their interests. The difference in practice between males and females and negotiation about the division of labour contribute to constructing gendered work cultures.

Silverleaf is an important fungal trunk disease of fruit crops, such as Japanese plum (Prunus salicina). It is known that infection by Chondrostereum purpureum results in discolored wood, “silvered” foliage, and tree decline. However, effects on fruit yield and quality have not been assessed. Therefore, the objectives of this study were to determine C. purpureum pathogenicity on P. salicina and the effects on physiology, fruit yield, and quality, in Chile, in 2019 and 2020. Wood samples from affected plum trees were collected in the Chilean plum productive area. Fungi were isolated by plating wood sections from the necrosis margin on culture media. Morphological and molecular characteristics of the isolates corresponded to C. purpureum (98%). Representative isolates were inoculated from healthy plum plants and after 65-d incubation, wood necrotic lesions and silver leaves were visible. Fungi were reisolated, fulfilling Koch’s postulates. To determine Silverleaf effects, xylem water potential and fruit yield and quality were measured in healthy and Silverleaf-diseased plum trees ‘Angeleno’. Water potential was altered in diseased trees, and fruit yield was reduced by 51% (2019) and by 41% (2020) compared to fruit from healthy trees. Moreover, cover-colour, equatorial-diameter, and weight were reduced, and fruit were softer, failing to meet the criteria to be properly commercialized and exported to demanding markets.
