    Nursing students’ attitudes towards the use of digital technology in the healthcare of older adults- a cross-sectional study in Norway and Sweden2023In: BMC Nursing, ISSN 1472-6955, E-ISSN 1472-6955, Vol. 22, no 1, article id 428Article in journal (Refereed)
    Abstract [en]

    Background: Implementation of digital technology has been suggested as a potential solution to future healthcare challenges. Healthcare personnel’s attitudes are important in the acceptance and implementation of digital technologies. Aim: The aims of this study were to (1) translate and validate two different questionnaires to Norwegian and Swedish respectively, and then (2) use these to examine nursing students’ attitudes towards digital technology in healthcare, as well as their attitudes towards older adults’ abilities to use digital technology. Design: Cross-sectional. Methods: A web-based questionnaire was distributed in first year nursing students in a Norwegian and a Swedish university college, respectively. The questionnaire consisted of the short form of the ‘Information Technology Attitude Scales for Health (ITASH)’ and the ‘Attitudes Towards Older Adults Using Digital technology (ATOAUT-11)’ questionnaire. The questionnaires were translated and validated in both countries. Frequencies, Student’s t-test, and one-way ANOVA were used to analyze the data. Results: In total 236 students responded to the questionnaire in the period September 2022 to April 2023. Students mainly reported positive attitudes towards digital technology use in general. They most agreed with the items ‘Using digital technology devices makes my communication with other health professionals faster’, ‘The sort of information I can get from the digital technology devices helps me give better care to patient’, and ‘Digital technology skills are becoming more and more necessary for healthcare professionals’. However, they reported more negative attitudes towards older adults using digital technology. They most agreed with the items ‘One needs a lot of patience to explain to an older adult how to use digital technologies’, ‘It’s hard to explain to older adults how to use digital technology’, ‘Using digital technology is harder for most older adults’, and ‘Most older adults fear using digital technology because they fear of being scammed or cheated’. Conclusion: The ITASH and the ATOAUT-11 is appropriate for use in a Norwegian and Swedish setting. Even if nursing students are positive to digital technology in healthcare in general, they are sceptical to older adults using digital technology. This may impact on their attitudes to using digital technology in the healthcare of older adults. These aspects need emphasis when revising nursing education curricula focusing on developing technological competencies in nursing, and gaining knowledge regarding older adults’ use of digital technology.

    Potential effectiveness and efficiency issues in usability evaluation within digital health: A systematic literature review2024In: Journal of Systems and Software, ISSN 0164-1212, E-ISSN 1873-1228, Vol. 208, article id 111881Article in journal (Refereed)
    Abstract [en]

    Context: Digital Health (DH) is widely considered essential for sustainable future healthcare systems. Software quality, particularly usability, is crucial for the success and adoption of most DH products. However, concerns about the effectiveness and efficiency of usability evaluation of DH products have been raised. Objective: This article aims to analyse the prevalence and application contexts of usability evaluation methods in DH and to highlight potential issues related to their effectiveness and efficiency. Method: A systematic literature review of usability evaluation studies, published by (academic) practitioners between 2016 and April 2023, was conducted. 610 primary articles were identified and analysed, utilising five major scientific databases. Results: Our findings show a preference for inquiry (85%) and testing (63%) methods, with inspection used less frequently (17%). The published studies employed methods like questionnaires (75%); notably the SUS (49%), semi-structured interviews (25%), and heuristic evaluations (73%), with percentages based on their group. Data collection mainly involved the use of participant feedback (45%), audio/video recordings (44%), and system logs (20%), with both qualitative and quantitative data analyses prevalent in studies. However, several usability characteristics such as accessibility, memorability, and operability were found to be largely overlooked, and automation tools or platforms were not widely used. Among the systems evaluated were mHealth applications (70%), telehealth platforms (36%), health information technology (HIT) solutions (29%), personalized medicine (Per. Med.) (17%), wearable devices (12%), and digital therapeutics (DTx) interventions (6%), with the participation of general users, patients, healthcare providers, and informal caregivers varying based on the health condition studied. Furthermore, insights and experiences gathered from 24 articles underscored the importance of a mixed-method approach in usability evaluations, the limitations of traditional methods, the necessity for sector-specific customisation, and the potential benefits of remote usability studies. Moreover, while eye-tracking emerged as a promising evaluation technique, careful execution and interpretation are crucial to avoid data misinterpretation. Conclusion: The study’s findings showed that employing a combination of inquiry and testing-based methods is prevalent for evaluating DH platforms. Despite an array of DH systems, method distribution remained consistent across platforms and targeted user groups. The study also underlines the importance of involving target user groups in the process. Potentially affected cognitive abilities of participants and potential user groups of interest have to be taken into account when choosing evaluation methods, and methods might therefore need to be tailored. Complementary inspection methods might be particularly useful when recruiting representative participants is difficult. Several potential paths for future research are outlined, such as exploring novel technologies like artificial intelligence, for improved automation tool support in the usability evaluation process.

    Circular service management: toward conceptual understanding and service research priorities for a more sustainable future2023In: Journal of Service Management, ISSN 1757-5818, E-ISSN 1757-5826, Vol. 34, no 6, p. 50-69Article in journal (Refereed)
    Abstract [en]

    Purpose: Service managers increasingly strive to achieve sustainability through strategies centered on circularity. With a focus on saving, extending and (re)generating resources and their enclosing service systems, circularity can contribute to environmental, social and financial gains. Yet, the notion of circularity is surprisingly understudied in service research. This article seeks to provide an initial conceptual understanding of circular service management, introducing illustrative strategies and research priorities for circular service management. This paper provides a roadmap for scholars, practitioners and policymakers to develop a deeper understanding of the opportunities from adopting circular services. Design/methodology/approach: The authors explore the concept of circular service management by drawing upon existing literature on sustainability, circularity and service research. Strategies of circular service management and research priorities emerge on the basis of industry best practice examples and research on sustainability challenges and opportunities. Findings: Service researchers have largely ignored the concept and role of circularity for service businesses. Extant research on the topic nearly exclusively features in non-service journals and/or does not seek to advance service theory through circularity. This article argues that circular service management enables the implementation of service thinking in the pursuit of sustainability and outlines four types of circular service management strategies. Originality/value: The authors introduce the concept of circular service management and highlight the role of service research for designing and managing circular systems and operations. This article also offers a research agenda connecting managerial challenges and opportunities with key service research priorities for circular service management. This provides a roadmap for scholars, practitioners and policymakers to develop a deeper understanding of pursuing circular services, thereby contributing to a more sustainable future.

    Interventions for improving mental health in athletes: a scoping review2023In: International Review of Sport and Exercise Psychology, ISSN 1750-984X, E-ISSN 1750-9858Article, review/survey (Refereed)
    Abstract [en]

    The aims of this scoping review were to map the current literature on interventions for improving mental health in athletes, identify knowledge gaps, and generate future research questions. The Preferred Reporting Items for Systematic Review and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guided this review. A systematic literature search was conducted in SPORTDiscus, PsycINFO, and SCOPUS and 44 intervention studies met the inclusion criteria. Results showed that 22 studies (50%) implemented cognitive behavioural principles, and the majority of these studies were influenced by various mindfulness programmes. Most studies (93%) included healthy athlete samples, and athletes aged 15–19 were the most examined age group (43%). Only three studies used clinical criteria in their sampling of participants and mediators were examined in two studies. The scarcity of studies examining mediators and subclinical or clinical samples revealed critical knowledge gaps in the literature. Furthermore, the critical appraisal showed that regardless of study design, most studies demonstrated low internal validity. We propose the use of high-quality single-case studies with athletes who experience subclinical or clinical mental health issues, and further investigation of mechanisms of change linking intervention components to outcomes of interest.

    Unveiling the Three-Step Model for the Interaction of Imidazolium-Based Ionic Liquids on Albumin2023In: ACS Omega, E-ISSN 2470-1343, Vol. 8, p. 38101-38110Article in journal (Refereed)
    Abstract [en]

    The effect of the ionic liquids (ILs) 1-methyl-3-tetradecylimidazolium chloride ([C14MIM][Cl]), 1-dodecyl-3-methylimidazolium chloride ([C12MIM][Cl]), and 1-decyl-methylimidazolium chloride ([C10MIM][Cl]) on the structure of bovine serum albumin (BSA) was investigated by fluorescence spectroscopy, ultraviolet-visible (UV-vis) spectroscopy, small-angle X-ray scattering (SAXS), and molecular dynamics (MD) simulations. Concerning the fluorescence measurements, we observed a blue shift and a fluorescence quenching as the IL concentration increased in the solution. Such behavior was observed for all three studied imidazolium-based ILs, being larger as the number of methylene groups in the alkyl chain increased. UV-vis absorbance measurements indicate that even at relatively small IL/protein ratios, like 1:1 or 1:2, ([C14MIM][Cl]) is able to change, at least partially, the sample turbidity. SAXS results agree with the spectroscopic techniques and suggest that the proteins underwent partial unfolding, evidenced by an increase in the radius of gyration (Rg) of the scattering particle. In the absence and presence of ([C14MIM][Cl]) = 3 mM BSA Rg increases from 29.1 to 45.1 Å, respectively. Together, these results indicate that the interaction of BSA with ILs is divided into three stages: the first stage is characterized by the protein in its native form. It takes place for protein/IL ≤ 1:2, and the interaction is predominantly due to the electrostatic forces provided by the negative charges on the surface of BSA and the cationic polar head of the ILs. In the second stage, higher IL concentrations induce the unfolding of the protein, most likely inducing the unfolding of domains I and III, in such a way that the protein’s secondary structure is kept almost unaltered. In the last stage, IL micelles start to form, and therefore, the interaction with protein reaches a saturation point and free micelles may be formed. We believe that this work provides new information about the interaction of ILs with BSA. © 2023 The Authors. Published by American Chemical Society.

    Errors, Omissions, and Offenses in the Health Record of Mental Health Care Patients: Results from a Nationwide Survey in Sweden2023In: Journal of Medical Internet Research, E-ISSN 1438-8871, Vol. 25, article id e47841Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Previous research reports that patients with mental health conditions experience benefits, for example, increased empowerment and validation, from reading their patient-accessible electronic health records (PAEHRs). In mental health care (MHC), PAEHRs remain controversial, as health care professionals are concerned that patients may feel worried or offended by the content of the notes. Moreover, existing research has focused on specific mental health diagnoses, excluding the larger PAEHR userbase with experience in MHC. OBJECTIVE: The objective of this study is to establish if and how the experiences of patients with and those without MHC differ in using their PAEHRs by (1) comparing patient characteristics and differences in using the national patient portal between the 2 groups and (2) establishing group differences in the prevalence of negative experiences, for example, rates of errors, omissions, and offenses between the 2 groups. METHODS: Our analysis was performed on data from an online patient survey distributed through the Swedish national patient portal as part of our international research project, NORDeHEALTH. The respondents were patient users of the national patient portal 1177, aged 15 years or older, and categorized either as those with MHC experience or with any other health care experience (nonmental health care [non-MHC]). Patient characteristics such as gender, age, education, employment, and health status were gathered. Portal use characteristics included frequency of access, encouragement to read the record, and instances of positive and negative experiences. Negative experiences were further explored through rates of error, omission, and offense. The data were summarized through descriptive statistics. Group differences were analyzed through Pearson chi-square. RESULTS: Of the total sample (N=12,334), MHC respondents (n=3131) experienced errors (1586/3131, 50.65%, and non-MHC 3311/9203, 35.98%), omissions (1089/3131, 34.78%, and non-MHC 2427/9203, 26.37%) and offenses (1183/3131, 37.78%, and non-MHC 1616/9203, 17.56%) in the electronic health record at a higher rate than non-MHC respondents (n=9203). Respondents reported that the identified error (MHC 795/3131, 50.13%, and non-MHC 1366/9203, 41.26%) and omission (MHC 622/3131, 57.12%, and non-MHC 1329/9203, 54.76%) were "very important," but most did nothing to correct them (MHC 792/3131, 41.29%, and non-MHC 1838/9203, 42.17%). Most of the respondents identified as women in both groups. CONCLUSIONS: About 1 in 2 MHC patients identified an error in the record, and about 1 in 3 identified an omission, both at a much higher rate than in the non-MHC group. Patients with MHC also felt offended by the content of the notes more commonly (1 in 3 vs 1 in 6). These findings validate some of the worries expressed by health care professionals about providing patients with MHC with PAEHRs and highlight challenges with the documentation quality in the records.

    Starting up user-focused monitoring projects: trust and conflicting expectations in user involvement practices2023In: Nordic Social Work Research, ISSN 2156-857X, E-ISSN 2156-8588Article in journal (Refereed)
    Abstract [en]

    User-focused monitoring (UFM) is an emerging method for user involvement and quality development in the Swedish mental health sector. It involves people with lived experience conducting a systematized evaluation of a mental health service or support programme. The aim of this study is to analyse motives and central concerns when initiating a UFM project. Five UFM projects in Sweden were sampled, 16 semi-structured interviews were performed with user monitors and commissioners and analysed using conventional content analysis. Our results showcase a range of motives for conducting UFM, illustrate the centrality of trust in the relationships of the UFM practice and the varying degrees of user autonomy in UFM projects. We further discuss our results in relation to epistemic trust and organizational learning theories. Accountability processes are discussed as important for securing continuous trust between the stakeholders. Furthermore, trust is required for UFM being applied to engage in continuous learning and review of organizational norms and goals together with service users.

    Magnetron sputtered high entropy alloy/amorphous carbon nanocomposite coatings2023In: Materials Today Communications, ISSN 2352-4928, Vol. 37, article id 107389Article in journal (Refereed)
    Abstract [en]

    Magnetron sputter deposition of metal/carbon nanocomposites has been explored for many metals and a few alloys. In this paper, the formation of nanocomposites based on complex high entropy alloys (HEAs) was explored, focusing on the effect of the average carbon affinity on the phase formation. Two HEA systems were compared: CoCrFeMnNi and Cr26Fe27Ni27Ta20. For each alloy, around 20–50 at% carbon was added through combinatorial co-sputtering. Thermodynamic calculations predicted decomposition of these materials into multiple alloy phases, metal carbides, and, at higher concentrations, free graphitic carbon. Free carbon was found in the coatings at carbon concentrations above 28 and 33 at% for the CoCrFeMnNi and Cr26Fe27Ni27Ta20 systems, respectively, which agreed with the theoretical predictions. However, the segregation of metallic elements and the formation of crystalline carbides were suppressed by the rapid quenching during deposition. All coatings were, instead, amorphous and consisted of either a single metallic phase or a mixture of a metallic phase and sp2- and sp3-hybridized carbon. Mechanical and electrochemical tests were performed, including in-situ fragmentation tests to quantify the crack resistance. The presence of free carbon made the coatings softer than the corresponding single-phase materials. Under tensile strain, the nanocomposite coatings formed a larger number of narrower cracks and exhibited less delamination at high strains.

    Emotional arousal in customer experience: A dynamic view2024In: Journal of Business Research, ISSN 0148-2963, E-ISSN 1873-7978, Vol. 170, article id 114344Article in journal (Refereed)
    Abstract [en]

    Customer emotion in services has been extensively studied, but prior research has overlooked the dynamics of emotion over time. Our research addresses this gap by studying how emotional arousal varies throughout a service encounter. Drawing from the psychology literature, we identify certain features (or patterns) that characterize how arousal varies throughout a service encounter and predict how they may affect customer approach response (e.g., spending, unplanned purchases). We explore the effect of these features in field studies in two stores using a psychophysiological measure (electrodermal activity) to capture arousal over time. We find that (1) the highest arousal level reached during the encounter and (2) the skewness of the distribution of arousal levels (i.e., the frequency of lower arousal levels relative to higher ones) predict customer approach response. This paper opens new avenues for understanding customers from an emotional perspective, which can improve the customer experience in service encounters.

    Quality of life, sense of coherence and occupational balance one year after an occupational therapy intervention for people with depression and anxiety disorders2023In: Work: A journal of Prevention, Assessment and rehabilitation, ISSN 1051-9815, E-ISSN 1875-9270, Vol. 76, no 2, p. 561-568Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Quality of life (QOL), sense of coherence (SOC) and occupational balance (OB) have been found to increase after rehabilitation among people living with depression and anxiety. However, these aspects have not been investigated over time in participants with different paid work situations, such as being on sick leave or not. OBJECTIVE: To describe and compare the self-rated QOL, SOC and OB after participation in occupational therapy in three groups of people with depression and anxiety disorders based on their work situation during the study period: continuous sick leave, return to work and continuous work. METHODS: Forty-seven women and seven men, 19-60 years old with depression and anxiety were followed over time. They completed questionnaires on QOL, SOC and OB on four occasions. Data were analyzed with non-parametric statistics. RESULTS: No statistically significant differences between the groups were identified. All groups improved in at least one of the studied areas over time: the sick leave group in OB; the return-to-work group in QOL and OB; and the Work group in QOL and SOC. CONCLUSION: The results indicate variations in QOL, SOC and OB between people with different work situations over time after occupational therapy. Studies with larger samples are, however, warranted.

    Collective pedagogical content knowledge for teaching sustainable development2023In: International Journal of Science and Mathematics Education, ISSN 1571-0068, E-ISSN 1573-1774Article in journal (Refereed)
    Abstract [en]

    It is vital that upper secondary students gain a rich and deep knowledge of sustainability issues, as they will enter adulthood and working life within a short time. The students belong to a generation that will be intensely involved in managing several environmental issues to achieve sustainable development for our Earth. However, earlier research indicates that many teachers have a low self-efficacy for teaching sustainability issues. This study aimed to explore how science teacher teams in Swedish upper secondary schools can develop their knowledge and expertise in sustainable development (SD) through collective reflections with the support of the reflective tool Content Representation (CoRe). Science teachers' pedagogical content knowledge (PCK) development in teaching SD was examined. Twelve in-service science teachers participated in the study. The qualitative research design included semi-structured interviews and science teacher teams' collective meetings. The findings covered four themes about how the collective reflections with support of the CoRe tool stimulated teachers' PCK development: (1) creating structure and a focus for learning conversations, (2) modification of the teaching approach, (3) development of new content knowledge and pedagogical knowledge in SD, and (4) shared language to stimulate equal opportunities for students to learn SD. The conclusion is that with the support of CoRe, the teacher team's collective PCK in SD was developed; therefore, we recommend that decision-makers within the school system organize regular meetings in science teacher teams and introduce CoRe to the teachers.

    Gradient Clipping in Deep Learning: A Dynamical Systems Perspective2023In: Proceedings of the 12th International Conference on Pattern Recognition Applications and Methods - ICPRAM, SciTePress, 2023, Vol. 1, p. 107-114Conference paper (Refereed)
    Abstract [en]

    Neural networks are ubiquitous components of Machine Learning (ML) algorithms. However, training them is challenging due to problems associated with exploding and vanishing loss-gradients. Gradient clipping is shown to effectively combat both the vanishing gradients and the exploding gradients problems. As the name suggests, gradients are clipped in order to prevent large updates. At the same time, very small neural network weights are updated using larger step-sizes. Although widely used in practice, there is very little theory surrounding clipping. In this paper, we analyze two popular gradient clipping techniques-the classic norm-based gradient clipping method and the adaptive gradient clipping technique. We prove that gradient clipping ensures numerical stability with very high probability. Further, clipping based stochastic gradient descent converges to a set of neural network weights that minimizes the average scaled training loss in a local sense. The averaging is with respect to the distribution that generated the training data. The scaling is a consequence of gradient clipping. We use tools from the theory of dynamical systems for the presented analysis.

    Geografilärares ämnesförståelse: Ämnesdidaktiska berättelser som reflektionsarena skapar kunskap om skolans geografi2023Licentiate thesis, monograph (Other academic)
    Abstract [sv]

    Kunskaper om och perspektiv på skolämnet geografi är viktiga när relationen mellan lärare och ämne sätt i fokus, särskilt om lärares ämnesspecifika förståelse betraktas som bärande för hur geografiämnet blir till i skolan.

    Syftet med denna studie är att utforska hur geografilärares ämnesspecifika förståelse kommer till uttryck och kan förstås när lärare själva får reflektera över ämnet och undervisningen. Resultaten visar på en bred variation i hur lärare förstår och resonerar om det egna ämnet. Analysen uppvisar skillnader i hur denna förståelse kan tolkas där två av fynden rör hur vardagens geografier inkluderas samt geografiämnets roll som beredskapsämne. Till det förs en diskussion om det ömsesidiga beroendeförhållandet mellan vad lärare upplever som möjligt och tillåtet, den kapacitet de har att agera, samt geografilärarens roll som medskapare av ämnet.

    Strategies for predictive modeling of overloaded oligonucleotide elution profiles in ion-pair chromatography2023In: Journal of Chromatography A, ISSN 0021-9673, E-ISSN 1873-3778, Vol. 1711, article id 464446Article in journal (Refereed)
    Abstract [en]

    Due to their potential for gene regulation, oligonucleotides have moved into focus as one of the preferred modalities modulating currently undruggable disease-associated targets. In the course of synthesis and storage of oligonucleotides a significant number of compound-related impurities can be generated. Purification protocols and analytical methods have become crucial for the therapeutic application of any oligonucleotides, be they antisense oligonucleotides (ASOs), small interfering ribonucleic acids (siRNAs) or conjugates. Ion-pair chromatography is currently the standard method for separating and analyzing therapeutic oligonucleotides. Although mathematical modeling can improve the accuracy and efficiency of ion-pair chromatography, its application remains challenging. Simple models may not be suitable to treat advanced single molecules, while complex models are still inefficient for industrial oligonucleotide optimization processes. Therefore, fundamental research to improve the accuracy and simplicity of mathematical models in ion-pair chromatography is still a necessity. In this study, we predict overloaded concentration profiles of oligonucleotides in ion-pair chromatography and compare relatively simple and more advanced predictive models. The experimental system consists of a traditional C18 column using (dibutyl)amine as the ion-pair reagent and acetonitrile as organic modifier. The models were built and tested based on three crude 16-mer oligonucleotides with varying degrees of phosphorothioation, as well as their respective n – 1 and (P = O)1 impurities. In short, the proposed models were suitable to predict the overloaded concentration profiles for different slopes of the organic modifier gradient and column load.

    Exploring the effects of target-language extramural activities on students’ written production2023In: Journal of second language writing, ISSN 1060-3743, E-ISSN 1873-1422, Vol. 62, article id 101062Article in journal (Refereed)
    Abstract [en]

    Frequent engagement in English extramural activities (i.e., activities that take place outside the classroom) has been found to have a positive impact on EFL learners’ vocabulary knowledge and reading comprehension. In the present study, we aim to extend our knowledge of the possible impact of extramural activities into the realm of second-language writing. Specifically, we investigate the relationship among a number of English extramural activities and two aspects of writing development: lexical diversity and noun phrase complexity. The data are drawn from the Swedish Learner English Corpus (SLEC) which includes texts produced by Swedish secondary school students. The corpus also includes information on how many hours per week students (i) engage in conversations in English, (ii) communicate in English while playing computer/video games, (iii) read in English, (iv) spend time on social media with English content, (v) and watch TV shows or movies in English. The results show that reading in English leads to higher frequency of adjectival modification, whereas conversing in English and watching TV programs positively impact lexical diversity. The results of the study have implications for discussions about the role of L2 classroom instruction vis-à-vis learners’ extramural activities.

    Validation of the Swedish version of the safe environment for every kid (SEEK) parent screening questionnaire2023In: BMC Public Health, E-ISSN 1471-2458, Vol. 23, no 1, article id 1989Article in journal (Refereed)
    Abstract [en]

    Background: Psychosocial risk factors in the home may impair children’s health and development and increase the risk of maltreatment. The Safe Environment for Every Kid (SEEK) model was developed to provide pediatric primary care professionals with a structured way to identify common psychosocial problems. The SEEK model includes use of the Parent Screening Questionnaire (SEEK-PSQ) at routine preventive child health visits, discussion with parents about their responses and, when indicated, referral to relevant services. The SEEK-PSQ has not previously been available in Swedish. The aim of the present study was to evaluate the psychometric properties of an adapted Swedish version of the SEEK-PSQ (PSQ-S). Methods: This study is part of a cluster-randomised controlled trial of SEEK in the Swedish child health services. To validate the PSQ-S, parents (n = 852) with children 0–18 months of age were invited to complete a survey including the PSQ-S as well as evidence-based standardized instruments for the targeted psychosocial risk factors: economic worries, depressive symptoms, parental stress, alcohol misuse and intimate partner violence (IPV). Baseline data from 611 (72%) parents were analysed regarding sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for each risk factor. Results: As a whole, the PSQ-S had a sensitivity of 93%, specificity of 52%, PPV of 67% and NPV of 87%. For mothers and fathers combined, sensitivity was 80% for economic worries, 89% for depressive symptoms, 78% for parental stress, 47% for intimate partner violence (IPV) and 70% for alcohol misuse. Specificity was highest for IPV and alcohol misuse (91%) and lowest for depressive symptoms (64%). NPV values were high (81–99%) and PPV values were low to moderate (22–69%) for the targeted problems. Sensitivity was higher for mothers compared to fathers for economic worries, depressive symptoms and IPV. This difference was particularly evident for IPV (52% for mothers, 27% for fathers). Conclusion: The SEEK-PSQ-S demonstrated good psychometric properties for identifying economic worries, depressive symptoms, parental stress and alcohol misuse but low sensitivity for IPV. The PSQ-S as a whole showed high sensitivity and NPV, indicating that most parents with or without the targeted psychosocial risk factors were correctly identified.

    Influence of taping on force sense accuracy: a systematic review with between and within group meta-analysis2023In: BMC Sports Science, Medicine and Rehabilitation, E-ISSN 2052-1847 , Vol. 15, no 1, article id 138Article in journal (Refereed)
    Abstract [en]

    Taping is a common technique used to address proprioceptive deficits in both healthy and patient population groups. Although there is increasing interest in taping to address proprioceptive deficits, little is known about its effects on the kinetic aspects of proprioception as measured by force sense accuracy. To address this gap in the literature, the present systematic review and meta-analysis was conducted to evaluate the impact of taping on force sense accuracy. A search for relevant literature was conducted following PRISMA guidelines across seven databases and one register. Eleven studies with 279 participants were included in the review out of 7362 records. In the between-group analyses, we found a significant improvement in absolute (p < 0.01) and relative (p = 0.01) force sense accuracy with taping compared to no comparator. Likewise, a significant improvement in absolute (p = 0.01) force sense accuracy was also observed with taping compared to placebo tape. In the within group analysis, this reduction in the absolute (p = 0.11) force sense accuracy was not significant. Additional exploratory subgroup analyses revealed between group improvement in force sense accuracy in both healthy individuals and individuals affected by medial epicondylitis. The findings of this meta-analysis should be interpreted with caution due to the limited number of studies and a lack of blinded randomized controlled trials, which may impact the generalizability of the results. More high-quality research is needed to confirm the overall effect of taping on force sense accuracy.

    Wound Management2024In: Fragility Fracture and Orthogeriatric Nursing: Holistic Care and Management of the Fragility Fracture and Orthogeriatric Patient / [ed] Karen Hertz, Julie Santy-Tomlinson, Springer, 2024, 2, p. 159-170Chapter in book (Refereed)
    Abstract [en]

    Wound healing is the process by which the function of damaged tissue is restored following surgery, trauma or other sources of tissue damage. The management of wounds is a fundamental aspect of the management of the patient following a fragility fracture, especially following a hip fracture and associated surgery. Ageing skin and multiple comorbidities are significant factors in skin injury and wound healing problems.

    The effective evidence-based management of surgical wounds following surgery after a fragility fracture can be challenging as ageing and comorbidities affect wound healing. Skin and wound care involves careful skin and wound assessment and attention to infection prevention measures while managing the factors affecting wound healing. Clinical considerations in wound management also include maintaining adequate nutrition, moisture, treating oedema and preventing further injury.

    This chapter aims to provide an overview of skin and wound assessment and evidence-based care interventions that can optimise wound healing in older people with fragility fractures.

    Abstract [en]

    Preventing pressure ulcers is fundamental in managing and caring for the patient following a fragility fracture. Patients who have sustained a hip fracture and have had associated surgery are at high risk as ageing skin, frailty, immobility, and multiple comorbidities are significant factors in skin injury.

    The causes of pressure ulcers are complex, and their prevention is the responsibility of the entire multidisciplinary team. Accessing evidence and education for practitioners is vital to making a difference in all aspects of care.

    The chorus of Begging and the chorus of Giving: What Images does the Begging face? What Images does the Giving face?2023Artistic output (Refereed)
    Abstract [en]

    The Chorus of Begging and The Chorus of Giving, 2014, (installation with two screens in the entrance hall of SSE) is part of the doctoral thesis in Fine Art “How do you become a successful beggar in Sweden? An inquiry into the images of begging and giving 2011 to 2016”, by Parsberg (Lund University).

    People who usually beg take part in the Begging Choir. People who usually give to those who beg participate in the choir of giving. Giving and receiving money is often a non-verbal transaction, which is why the Choir of Begging and the Choir of Giving sing without words. With their own individual voices as well as with their collective choral voice, they try to sing the feelings that exist between these begging and giving people. The choirs stood about five meters apart when the video was recorded.

    “The political happens every day. That is the premise for my artistic practice. I perceive, with all of my senses, a physical and mental distance between those who kneel on the street and passers-by, between begging and giving people. Here I invite the spectator into that “gap”. A dialogue, or a lack of dialogue is going on between the two choruses, between voices, between facial expressions, and between bodies. The installation The Chorus of Begging and The Chorus of Giving is an embodiment of this experiential space. A reflection of a situation that many experience every day on our streets. It is my hope that art can make it possible to see such gaps – which seem to be difficult to talk about – as spaces for action; and thus contribute to the possibility of political acts in and about these spaces.” – Cecilia Parsberg

    What Images does the Begging face? (2014)

    What Images does the Giving face? (2014)

    The two films screened in the north corridor of the grond floor (at lill-skärmen) are also part of Parsberg´s dissertation and they accompany the video installation in the main entrance hall. In “What Images does the Begging face?” Parsberg hired an interpreter and interviewed, with consent, fifteen begging persons about how they experience the giving, how they are treated on the streets of Sweden and what image they have of giving. In “What Images does the Giving face?” Parsberg hired a professional market researcher to conduct two qualitative group interviews with eight respondents. Each interview lasted two hours and was filmed, by consent, with two cameras. The starting point was to find out what a beggar in Sweden could do to get more money. The market researcher asked questions such as: How should the beggars behave in order for you to give? What should they wear? etc.

    User circularity practices: Adopting a user stewardship perspective for a circular economy2023In: AMS Review, ISSN 1869-814XArticle in journal (Refereed)
    Abstract [en]

    Humanity is depleting the planet’s natural resources at an unsustainable rate. The pursuit of a circular economy is a strong, viable means of reversing this trend; however, it will require users to take responsibility for the proper application and protection of resources for future generations. While the daily practices of users play a significant role in enabling a circular economy, this role has largely been overlooked in current literature. Our research synthesizes knowledge from the circular economy and marketing literatures, and draws on stewardship theory to better understand the user’s role in the circular economy. Specifically, we introduce a resource stewardship framework from a user perspective. This framework specifies a set of user circularity practices to minimize the extraction of finite resources, while conserving and regenerating resources already in circulation for future use. These practices occur at various stages in the resource life cycle and include minimizing the sourcing and use of finite resources, (re)designing products and services to use less resources, and optimizing the value potential from resources through extending their life cycle and recovering resources for future use. With this framework, we redefine the role of users as resource stewards and advance the rather narrow and fragmented considerations of user contributions to the circular economy, laying the foundation for more caring and responsible users and a future research agenda.

    Share or Protect: Understanding the Interplay of Trust, Privacy Concerns, and Data Sharing Purposes in Health and Well-Being Apps2023In: ACM International Conference Proceeding Series / [ed] Cristina Gena, Luigi De Russis, Davide Spano, Rosa Lanzilotti, Tania Di Mascio, Catia Prandi, Salvatore Andolina, Association for Computing Machinery (ACM), 2023, article id 15Conference paper (Refereed)
    Abstract [en]

    The popularity of health and well-being applications is on the rise. These applications often collect and process personal and sensitive information about individuals for different purposes. Nonetheless, users’ freedom of choice around protection and sharing may be compromised, for example, by forwarding such information to third parties without user awareness or control, especially with current developments in AI-based complex data processing technologies. Despite the popularity of health and well-being applications, the purpose of sharing and its interplay with trust, privacy concerns, and their antecedents is seldom explored. The present article addresses this gap by conducting an online study (N = 315), which shows that, generally, people’s sharing preferences depend on their trust and privacy concerns. However, the findings indicate potential differences between male and female participants considering sharing information for the greater good, such as scientific research. Our findings are discussed in light of sociocultural and social role theories of prosocial behavior and previous research. Considering the growing interest in building usable infrastructures for data sharing and user empowerment, practical implications for designers and policymakers are highlighted.

    Robust opportunistic optimal energy management of a mixed microgrid under asymmetrical uncertainties2023In: Sustainable Energy, Grids and Networks, E-ISSN 2352-4677, Vol. 36, article id 101184Article in journal (Refereed)
    Abstract [en]

    Energy management within microgrids under the presence of large number of renewables such as photovoltaics is complicated due to uncertainties involved. Randomness in energy production and consumption make both the prediction and optimality of exchanges challenging. In this paper, we evaluate the impact of uncertainties on optimality of different robust energy exchange strategies. To address the problem, we present AIROBE, a data-driven system that uses machine-learning-based predictions of energy supply and demand as input to calculate robust energy exchange schedules using a multiband robust optimization approach to protect from deviations. AIROBE allows the decision maker to tradeoff robustness with stability of the system and energy costs. Our evaluation shows, how AIROBE can deal effectively with asymmetric deviations and how better prediction methods can reduce both the operational cost while at the same time may lead to increased operational stability of the system.

    Can non-participants in a follow-up be used to draw conclusions about incidences and prevalences in the full population invited at baseline?: An investigation based on the Swedish MDC cohort2023In: BMC Medical Research Methodology, E-ISSN 1471-2288, Vol. 23, no 1, article id 228Article in journal (Refereed)
    Abstract [en]

    Background: Participants in epidemiological cohorts may not be representative of the full invited population, limiting the generalizability of prevalence and incidence estimates. We propose that this problem can be remedied by exploiting data on baseline participants who refused to participate in a re-examination, as such participants may be more similar to baseline non-participants than what baseline participants who agree to participate in the re-examination are. Methods: We compared background characteristics, mortality, and disease incidences across the full population invited to the Malmö Diet and Cancer (MDC) study, the baseline participants, the baseline non-participants, the baseline participants who participated in a re-examination, and the baseline participants who did not participate in the re-examination. We then considered two models for estimating characteristics and outcomes in the full population: one (“the substitution model”) assuming that the baseline non-participants were similar to the baseline participants who refused to participate in the re-examination, and one (“the extrapolation model”) assuming that differences between the full group of baseline participants and the baseline participants who participated in the re-examination could be extended to infer results in the full population. Finally, we compared prevalences of baseline risk factors including smoking, risky drinking, overweight, and obesity across baseline participants, baseline participants who participated in the re-examination, and baseline participants who did not participate in the re-examination, and used the above models to estimate the prevalences of these factors in the full invited population. Results: Compared to baseline non-participants, baseline participants were less likely to be immigrants, had higher socioeconomic status, and lower mortality and disease incidences. Baseline participants not participating in the re-examination generally resembled the full population. The extrapolation model often generated characteristics and incidences even more similar to the full population. The prevalences of risk factors, particularly smoking, were estimated to be substantially higher in the full population than among the baseline participants. Conclusions: Participants in epidemiological cohorts such as the MDC study are unlikely to be representative of the full invited population. Exploiting data on baseline participants who did not participate in a re-examination can be a simple and useful way to improve the generalizability of prevalence and incidence estimates.

    Calcite Surfaces Modified with Carboxylic Acids (C2 to C18): Layer Organization, Wettability, Stability, and Molecular Structural Properties2023In: Langmuir, ISSN 0743-7463, E-ISSN 1520-5827, Vol. 39, no 42, p. 14840-14852Article in journal (Refereed)
    Abstract [en]

    A fundamental understanding of the interactions between mineral surfaces and amphiphilic surface modification agents is needed for better control over the production and uses of mineral fillers. Here, we controlled the carboxylic acid layer formation conditions on calcite surfaces with high precision via vapor deposition. The properties of the resulting carboxylic acid layers were analyzed using surface-sensitive techniques, such as atomic force microscopy (AFM), contact angle measurements, angle resolved X-ray photoelectron spectroscopy (XPS), and vibrational sum-frequency spectroscopy. A low wettability was achieved with long hydrocarbon chain carboxylic acids such as stearic acid. The stearic acid layer formed by vapor deposition is initially patchy, but with increasing vapor exposure time, the patches grow and condense into a homogeneous layer with a thickness close to that expected for a monolayer as evaluated by AFM and XPS. The build-up process of the layer occurs more rapidly at higher temperatures due to the higher vapor pressure. The stability of the deposited fatty acid layer in the presence of a water droplet increases with the chain length and packing density in the adsorbed layer. Vibrational sum frequency spectroscopy data demonstrate that the stearic acid monolayers on calcite have their alkyl chains in an all-trans conformation and are anisotropically distributed on the plane of the surface, forming epitaxial monolayers. Vibrational spectra also show that the stearic acid molecules interact with the calcite surface through the carboxylic acid headgroup in both its protonated and deprotonated forms. The results presented provide new molecular insights into the properties of adsorbed carboxylic acid layers on calcite.

    Forests, Functions, and Food Webs: Riparian processes through an ecological and molecular lens2023Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Riparian systems are critical ecological interfaces that have a significant impact on the surrounding aquatic and terrestrial ecosystems. The riparian and surrounding systems have significant roles in regulating energy flow, providing essential nutrients, and supporting unique species, making them important for ecosystem function. Both the aquatic and terrestrial ecosystems are reliant on the reciprocal exchange of energy subsides to maintain productive and stable food webs. Retention of forested buffers along streams during tree felling operations is a common management technique used to protect aquatic resources and conserve the surrounding ecosystem processes. Measuring the effects of forestry practices on the function and food webs of riparian predators is vital to making forest management decisions that strengthen and protect these fundamental services. Insight into predator function and predator-prey interactions using powerful molecular techniques can further the understanding of these complex systems and help to mitigate the effects of forestry practices.

    This thesis explores the functional diversity, food webs, and predator-prey interactions in riparian systems impacted by forestry felling practices. I have studied the effects of clear-cutting and forested buffer zones on riparian functional diversity through the assessment of functional richness and redundancy of spider and plant communities. In addition, I have both validated and used stable isotope analysis and DNA metabarcoding to investigate the primary food sources and prey choices of riparian predators. Riparian buffer size had no direct effect on the functional richness or redundancy of riparian spiders and vascular plants. However, riparian buffer variables such as canopy closure, buffer density, and vegetation coverage did have direct impacts on both spider and plant function. Most riparian spiders and brown trout received a significant majority of their food source from the terrestrial environment and the presence or absence of a riparian buffer did not effect this outcome. However, web-weaving spiders in unbuffered systems were more likely to exploit aquatic resources as a primary food source. Overall, the responses of predator function and food webs to forestry practice are site-specific.

    Teachers’ Perspectives on Supportive and Inclusive Practices: A Study of Four Schools With Diverse Literacy Practices2023In: Nordic Journal of Literacy Research, E-ISSN 2464-1596, Vol. 9, no 2Article in journal (Refereed)
    Abstract [en]

    Previous research states that accessibility and participation are prerequisites for students, regardless of ability, to be able to develop in school. The point of accessibility and participation is that everyone should be able to feel included and have access to learning. From an inclusive education perspective, the interest of this study is how teachers work in diverse literacy practices to address a variety of student conditions and needs. By studying how some primary education teachers describe how they design and stage learning environments, we want to contribute new knowledge about inclusive literacy practices.&lt;/p&gt;&lt;p&gt;The data collection was carried out through focus group discussions. We analysed the data with Critical Literacy (CL) as a theoretical framework, and the related concepts of domination, access, diversity, and design were used. The general impression that emerges from our study is that teachers design literacy activities based on both supportive and inclusive aspects and with a focus on variation and diversity. In the study, more similarities than differences emerged, for instance a focus on multimodal methods and the importance of didactic flexibility. The teachers also highlighted the importance of producing text, not just consuming and processing existing texts. Sometimes the analysis reveals differences. Even so, the teachers’ intentions to include all students in the classroom education remain significant.

    2023 Roadmap on molecular modelling of electrochemical energy materials2023In: Journal of Physics: Energy, E-ISSN 2515-7655, Vol. 5, no 4, article id 041501Article in journal (Refereed)
    Abstract [en]

    New materials for electrochemical energy storage and conversion are the key to the electrification and sustainable development of our modern societies. Molecular modelling based on the principles of quantum mechanics and statistical mechanics as well as empowered by machine learning techniques can help us to understand, control and design electrochemical energy materials at atomistic precision. Therefore, this roadmap, which is a collection of authoritative opinions, serves as a gateway for both the experts and the beginners to have a quick overview of the current status and corresponding challenges in molecular modelling of electrochemical energy materials for batteries, supercapacitors, CO2 reduction reaction, and fuel cell applications.

    No clear connections: a study of the association between news media use, public trust, and Swedish social services2023In: European Journal of Social Work, ISSN 1369-1457, E-ISSN 1468-2664Article in journal (Refereed)
    Abstract [en]

    News and media reports on social work have had policy and legislative consequences for social work practice in Sweden. Generally, it is often argued that media reports have negative implications for public perception and public trust towards social services. However, empirical studies supporting such claims are rare. Going back to the classic theory of cultivation regarding media effects, this study investigates possible associations between news media use, public trust in news, and public trust towards social services in Sweden. Analyses are based on survey data from a representative sample of Swedish adults and young adults (n = 1 697) and linear regressions have been applied. In contrast to assumptions in the existing literature, no associations were identified between the level of news use, preferred news outlet and public trust towards the social services, whereas trust in news predicted trust in social services. The findings challenge dominating notions on the implications of news media use and public trust in social services. In short, news reports of the social services do not simply translate into public (dis)trust. This also enable, linear regressions has been applied. In contrast to assumptions in existing literature, no associations.

    Developing sustainable service user involvement practices in mental health services in Sweden: the "Userinvolve" research program protocol2023In: Frontiers in Psychiatry, E-ISSN 1664-0640, Vol. 14, article id 1282700Article in journal (Refereed)
    Abstract [en]

    Background: The purpose of this paper is to outline the protocol for the research program "UserInvolve," with the aim of developing sustainable, service user involvement practices in mental health services in Sweden.Methods: This protocol outlines the knowledge gap and aim of the UserInvolve-program. It further provides an overview of the research infrastructure, with specific focus on the organization and management of the program as well as the design of the six underlying research projects. These six research projects form the core of the UserInvolve-program and will be carried out during a six-year period (2022-2027). The projects are focused on examining articulations of experiential knowledge in user collectives, on four specific user involvement interventions (shared decision-making, peer support, user-focused monitoring, and systemic involvement methods) and on developing theory and method on co-production in mental health research and practice.Results or conclusion: The knowledge gained through the co-production approach will be disseminated throughout the program years, targeting service users, welfare actors and the research community. Based on these research activities, our impact goals relate to strengthening the legitimacy of and methods for co-production in the mental health research and practice field.

    Construction of learning environments: A multiple case study in special education settings2023In: Journal of Research in Special Educational Needs, E-ISSN 1471-3802Article in journal (Refereed)
    Abstract [en]

    Education in segregated settings for pupils with intellectual disability (ID) has often been portrayed as a unified form of schooling. There is a risk of providing a simplified picture of these settings and of what pupils with ID need to learn. This is generally stipulated in policy documents, leaving room for staff in school to interpret curricula and form learning environments. The aim of this study is to explore how four different learning environments are constructed in segregated settings where pupils with ID are educated in Sweden. The study was conducted as a multiple case study, using observations and interviews with teachers and pupils in four special classes for pupils with ID (SCIDs). Drawing on curriculum theory, the four learning environments, in the results named as Alpha, Beta, Gamma and Delta class, respectively, appeared to be characterized by different ideas of schooling, labelled as knowledge-mediating, socializing, functional life skills and caring as well as teacher-centred classrooms. The study contributes to a deepened understanding of the complexity of education for pupils with ID in segregated settings.

    Resource entanglement and indeterminacy: Advancing the service-dominant logic through the philosophy of Karen Barad2023In: Marketing Theory, ISSN 1470-5931, E-ISSN 1741-301XArticle in journal (Refereed)
    Abstract [en]

    Resources are central to value creation processes. Hence, marketing and service research rely heavily on conceptualisations of resources and resource integration for theory building efforts. One of the most widely accepted marketing lenses on resources and resource integration is the service-dominant (S-D) logic. Depicting resources as becoming and contextual, S-D logic argues that their usefulness co-depends on other resources. Some assumptions of S-D logic have been challenged particularly its dichotomous categorisation of operand and operant resources. To inform ongoing S-D logic theorising, our article problematises the multiple and contradictory ontological views upon resources and resource integration present within S-D logic. Moving beyond critique, we propose concrete means for reconciling these contradictions. Seeing a parallel between S-D logic's ontological inconsistencies and past ontological disagreements in the philosophy of science, we draw on the philosophical perspective of Karen Barad to develop a consistent onto-epistemological foundation for conceptualising the becoming nature of resources in S-D logic. The theory adaptation we perform enhances the applicability and explanatory capacity of S-D logic, while also offering a more robust and rigorous foundation for marketing and service research at large and giving managers new means to make sense of co-dependent resource phenomena.

    The Importance of Information Processing in Child Protection Cases-A Study of Social Workers' Integration of Other Professionals' Knowledge2023In: British Journal of Social Work, ISSN 0045-3102, E-ISSN 1468-263XArticle in journal (Refereed)
    Abstract [en]

    The processes used by social workers to collect, interpret and use stakeholder information in child protection cases are an unexplored but essential part of the decision-making process. This study focuses on social workers' efforts to integrate the knowledge of other professionals. This article draws on a framework for managing knowledge across organisational boundaries and a process-oriented conceptualisation of knowledge integration. The analysis of ten interviews with social workers shows that the process of knowledge integration affects the basis of social workers' decision making. We argue that knowledge possessed by other professionals is often viewed as easily transferrable and correctly received, when in fact this knowledge is often complex and subjective and requires extra effort to obtain, understand and integrate into case-specific situations. This implies a need to recognise information processing as an influencing factor in decision making within child protection that pertains to both practice and research. Our study is based on ten in-depth interviews with child protection social workers. We focus on the significance of the process of collecting and interpreting information from other professionals (boundary work), information which contributes to the social workers' assessments and decision making. We found that despite the efforts made by the social workers to obtain and understand knowledge from other professionals, this knowledge transfer had limitations. These limitations can weaken the foundation upon which decisions in child protection services are made. We suggest that: (i) child protection services pay more attention to the boundary work; at the organisational level by facilitating collaboration between organisations and at the individual level by enhancing the social workers' interpersonal collaborations skills and (ii) child protection research should include boundary work as an influencing factor on the decision-making process.

    Are we leaving some people behind? Travel autonomy, perceived accessibility, and well-being among people experiencing mental and physical difficulties2023In: Transportation Research Part F: Traffic Psychology and Behaviour, ISSN 1369-8478, E-ISSN 1873-5517, Vol. 98, p. 243-253Article in journal (Refereed)
    Abstract [en]

    This study focuses on the association between cognitive, medical, and physical difficulties; mental illness; travel autonomy; and perceptions of the possibilities of participating in desired daily activities; further, we examine their association with happiness and life satisfaction. We present and empirically test an integrated framework with travel autonomy, defined as the prerequisites, freedom, and possibility to travel the way one wants, at its core. We use web survey data (n = 1041) collected in Sweden in 2021. Using partial least squares structural equations, we find a valid and reliable model with travel autonomy as a distinct and reliable latent construct. Furthermore, travel autonomy yields significant paths to perceived accessibility, happiness, and life satisfaction, highlighting the importance of capabilities, independent travel, freedom, and possibilities in the overall construct of travel autonomy. Finally, mental illness plays an important role in how people rate their travel autonomy.

    Early life environmental exposures and children's growth: A longitudinal study evaluating prenatal exposure for endocrine disrupting chemicals and nutrition in relation to children's growth up to seven years of age2023Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Endocrine disrupting chemicals (EDCs) have the potential to disrupt the endocrine system in humans and animals with importance for health and development. Additionally, optimal nutrition during pregnancy is critical for fetal growth and pregnancy outcomes. However, further knowledge on the importance of EDC mixtures and nutrition, on birthweight and growth during childhood is needed. 

    The overall aim of this thesis was to evaluate the associations between prenatal exposure to EDC mixtures and nutrition respectively, with birthweight, growth and body composition in early- and mid-childhood, and to determine if these associations differed by sex. Data from mother-child pairs in the Swedish Environmental Longitudinal, Mother and child, Asthma and allergy (SELMA) study was analyzed, including 26 EDCs in prenatal urine and serum samples, children’s anthropometric and body composition measures up to seven years of age, and sociodemographic data from questionnaires and registers.

    Results suggest that higher prenatal exposure to EDC mixtures were associated with lower birthweight, and slower weight gain in early childhood, including a later peak growth velocity among girls. At 5.5 and 7 years of age, EDC mixtures were associated with lower BMI, less odds of overweight and less body fat among girls, but more body fat among boys at 7 years of age. Chemicals of concern in the mixtures were e.g., phthalates, bisphenols, perfluorinated alkyl substances (PFASs) and pesticides. Finally, maternal nutrition during pregnancy, i.e., better adherence to nutritional guidelines, was associated with more body fat for boys but less body fat for girls.

    In conclusion, prenatal exposure to both EDC mixtures and nutrition suggests to have an influence on birthweight, and children´s growth. Several of the found associations also differed by sex.

    Show me love: Emergent strategic communication practices and fan engagement within the popular music industry2023Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis studies how the music industry’s strategic communication practices interplay with and steer audience and fan engagement. Relationships with, and expectations on, “active”, “prosuming” or “co-creative” music audiences make it imperative for communication practitioners to produce engagement. The music industry has adapted its promotional strategies accordingly, and data-driven processes and algorithms have become ever more central to understanding and controlling audience practices. Currently, we are witnessing the emergence of new strategic communication approaches to follow, foster, steer, track and commodify audience engagement, via big data. Applying qualitative and ethnographic approaches and socio-cultural perspectives, the thesis explores how strategic communication practices are enacted and designed to cater for, interplay with and steer fan engagement. Drawing on practice and structuration theory, critical questions are asked about the social consequences of communication engagement and an engagement imperative – for both individuals and organisations involved in the strategic communication around a music brand.  Results indicate that the contemporary, digitalised music industry demands communication practices that are at the same time strategic, professionalised, agile and co-creative. The study highlights important implications of such practices, in terms of changing professional competences and ethics as well as context-specific articulations of the power relations that support and are (re-)produced through the engagement imperative. In sum, the thesis is aimed at extending our understanding of how strategic communication practices respond to, and change in, a seemingly liquid, yet at the same time carefully orchestrated, communicative context.

    Modeling of modulus and strength in void-containing clay platelet/cellulose nanocomposites by unit cell approach2023In: Nanocomposites, E-ISSN 2055-0332, Vol. 9, no 1, p. 138-147Article in journal (Refereed)
    Abstract [en]

    Clay platelets/cellulose nanofibril nanocomposites are recyclable engineering materials of interest for sustainable development. There is substantial experimental data for mechanical properties, but modeling efforts are scarce. Here, a conceptual unit cell with voids was used in finite element modeling. Predictions for the in-plane modulus taking voids into account were more accurate than the classical rule of mixtures. Simulations also reveal that the cellulosic matrix undergoes shear and tensile deformation with inclined fracture located near the end of platelets for low clay content while predicting brittle tensile failure for high clay content. The results from the unit cell approach provide improved understanding of experimental observations, supporting the strive to better understand mechanisms of deformation and fracture.

    The self-perceived impact of sexual abuse on daily life and general health - an issue to consider in dental care2023In: Dental Traumatology, ISSN 1600-4469, E-ISSN 1600-9657Article in journal (Refereed)
    Abstract [en]

    Background/Aim: To analyse, from the perspective of adults with a history of sexual abuse, the impact of the experience on their general health and well-being.

    Material and Methods: The participants comprised 12 strategically selected informants (10 women), aged 19-56; all sexually abused during child- and/or adulthood. They were interviewed in-depth and encouraged to describe the impact of the sexual abuse on their daily lives. The consequences of sexual abuse on oral health have previously been reported. The interviews were recorded digitally, transcribed verbatim and analysed according to qualitative content analysis with an inductive approach.

    Results: The overall theme illustrating the latent content was Sexual abuse experience-limiting long-term consequences, always present in body and mind. The first category covering the manifest content was 'A lost foothold', with two subcategories: (i) emotional repercussions and (ii) physical health repercussions. The second category was 'The significance of distance to trauma', with two subcategories (i) keeping a distance and tending to escape and (ii) processing the trauma experience-a struggle towards balance.

    Conclusions: A history of sexual abuse cannot be understood in isolation: the long-term repercussions pervade daily life. However, after disclosure of the abuse and processing the trauma, it is possible to ameliorate some of the negative effects. In this context, the dental setting emerges as a potentially important venue for disclosure as almost every person, sooner or later, visits the dentist.

    Computing the stress intensity factor range for fatigue crack growth testing at 20 kHz2023In: Engineering Reports, ISSN 2577-8196Article in journal (Refereed)
    Abstract [en]

    Inertia and damping influence the values of the stress intensity factors (SIFs) at high-frequency loading and they must be included in computations. In the present study, different dynamic simulation procedures were carried out for two types of specimen geometries and the achieved SIF values were compared. Fast computation procedures such as harmonic modal analysis and direct steady-state analysis were compared to the computationally expensive transient dynamic analysis. Two different methods for calculating the SIF, the J-integral and the crack tip opening displacement (CTOD) methods, were applied and compared and the results showed a near perfect agreement in calculation of the mode I SIF. The Rayleigh damping model was introduced into the dynamic computation to investigate its effect and the results revealed a clear effect on the SIF at 20 kHz frequency. The fast direct steady-state analysis showed good agreement to both harmonic modal and transient analysis with the different damping values used and is, after this study, the recommended procedure.

    The impact of stroke on spousal and family income: a difference-in-difference study from Swedish national registries2023In: Topics in Stroke Rehabilitation, ISSN 1074-9357, E-ISSN 1945-5119Article in journal (Refereed)
    Abstract [en]

    AimTo investigates the financial consequences in the overall population spouses of persons with stroke in Sweden as well as for subgroups based on spouses age, sex and modified Rankin Scale (mRS) of the person with stroke.MethodsThe study population consists of spouses aged <= 60 during the year of their partner's stroke event. Each spouse was matched to four reference individuals. This longitudinal registry data covers spouses and a reference population between 2005 and 2016. We use difference-in-differences to estimate the impact on individual income from paid work, disposable individual income, and disposable family income.ResultsThe primary analysis shows a small and statistically insignificant decrease on spouses' individual income from paid work and disposable individual income. In the subgroup analysis based on mRS, the largest effect is seen in mRS 4-5, where spouses' individual income from paid work and disposable individual income increases after their partner's stroke. Further, younger female spouses' individual income from paid work decreases by 1 614 EUR (p = 0.008) on average.ConclusionThe financial consequences are small in the overall population of spouses. However, for some subgroups, younger women, and spouses of persons with stroke and mRS 4-5, the financial consequences are more prominent.

    Belonging to a research-practice partnership: Lessons from 15 think-pieces about the COVID-19 pandemic and a call for action2023In: The Journal of the learning sciences, ISSN 1050-8406, E-ISSN 1532-7809Article in journal (Refereed)
    Abstract [en]

    Research-Practice Partnerships (RPPs) in education have been gaining increasing currency and support since well before the advent of COVID-19. This article reflects on what the pandemic experience has meant for some RPPs so far, and imagines what other RPPs might look like in the near future. The authors share a collection of fifteen think-pieces written by individuals working in or around, or funding RPPs during the COVID crisis. These contributions include reflections on how the pandemic affected existing RPPs and how teams responded to the disruptions, how the larger context in which RPPs operate matters, as well as how RPPs can help us build a more just and united society. The authors identify lessons to be drawn from across these think-pieces and implications for the field, and close with a call for action about learning scientists' possibilities for belonging to RPPs. Through a somewhat unconventional form of scholarship, this article intends to spark and enrich conversations about tensions and choices facing RPPs and learning sciences scholarship broadly in the coming years.

    Abstract [en]

    Aims and Objectives: To explore nurse assistants' experiences and knowledge of how they create a meaningful daily life for older people receiving municipal home healthcare.Design: A participatory appreciative action reflection approach.Methods: Interviews, participant observations and informal conversations with 23 nurse assistants in municipal home healthcare generated the data. A thematic analysis was used.Results: Two main themes were developed. The first main theme, building a reciprocal relationship, was structured by three subthemes: To strengthen the older person's self-esteem, to co-create care and to create equality. The second main theme, creating meaning, was structured by two subthemes: To create closeness and to receive appreciation. The two main themes are each other's prerequisite. Nursing assistants' building reciprocal relationships gives meaning; through the meaning, reciprocal relationships are achieved, and by that, meaningful daily lives for both the older people and the nurse assistants.Conclusion: Nurse assistants built a reciprocal relationship both for the older people and for the nurse assistant. This contributes to create a meaningful daily life for the older people. The older person was the main character, and it seems that the nurse assistants apply person-centred care, which can represent a shared common vision that can be used in the encounter.

    To pay or not to pay?: Parents' view of the commercialisation process in children and youth sports2023In: European Journal for Sport and Society, ISSN 1613-8171Article in journal (Refereed)
    Abstract [en]

    The commercialisation of children's and youth sports has experienced a significant rise in recent decades. Currently, there is a lack of in-depth knowledge regarding the implications of this commercialisation for Swedish youth participating in sport as well as family members directly involved in the youth sport experience. As such, the purpose of this study was to investigate parents' perceptions of commercialisation processes in children and youth sports in Sweden. In particular, we sought to examine why some parents are willing to pay for commercial alternatives and how the increased commercialisation of youth sport are associated with youth sport participation. We also sought to investigate parents' views about the impact of commercialised alternatives on coaches and voluntary sports clubs, both now and in the future. A total of nine focus group interviews were conducted, including a total of 48 parents (22 men and 26 women) strategically chosen based on their children's participation in different strands of commercialised sports businesses. The findings indicate that the excessive demands from voluntary sports clubs combined with the desire to be considered a good parent appear to influence parents' willingness to pay for commercialised businesses.

    Renegotiating state-third sector relations through collaborative partnerships: The case of reception services for asylum-seeking children in Gothenburg, Sweden2023In: Journal of Civil Society, ISSN 1744-8689, E-ISSN 1744-8697Article in journal (Refereed)
    Abstract [en]

    Unprecedented numbers of unaccompanied minors entering Sweden in 2015, alongside other challenging social issues, have contributed to renegotiating collaborative forms of local governance in the country. This has resulted in an emergence of collaborative partnerships between civil society and public actors (Ideburna offentliga partnerskap or IOP), as real alternative to the market-based contracts and traditional state grants. This article addresses IOP from a collaborative governance perspective and questions if and how it may cope with a major and well known governance challenge, that of balancing the different roles and principles of public and civil society realms, so as to sustain an effective and legitimate cross-sectorial partnership. It asks, may and how an IOP enable civil society organisations a more active role in co-designing and co-implementing local welfare services with public sector actors without undermining their distinctiveness? The arguments are based on a case study of, at the time, the largest IOP in Sweden initiated for early reception of unaccompanied minors in Gothenburg city. The partnership is assessed against a normative theoretical framework of balanced state-third sector relations. The results suggest that IOPs, under certain conditions, may serve as 'spaces of hope' for more balanced power relations in local governance models.

    The effects of egg incubation temperature and parental cross on the swimming activity of juvenile brown trout Salmo trutta2023In: Behavioral Ecology and Sociobiology, ISSN 0340-5443, E-ISSN 1432-0762, Vol. 77, no 10, article id 114Article in journal (Refereed)
    Abstract [en]

    Personality varies among individuals and is influenced by the environment. Here, we tested the hypothesis that egg incubation temperature had carry-over effects on swimming activity of juvenile brown trout, Salmo trutta. Eggs from different crosses involving anadromous and lacustrine-adfluvial parents were incubated under two temperature regimes, unheated (cold) or heated c. 2.5 degree celsius above ambient temperature (warm), until first exogenous feeding. In the laboratory, we used open-field tests to quantify swimming activity in a new environment, and mirror-image tests to measure time spent swimming and resting motionless near a mirror, measures often used as proxies for aggression. These tests were conducted for two cohorts, with one tested in June 2018 and the other in June and August 2019, enabling us to test for repeatability and if differences persisted over the summer. In June, when adjusting for differences in body size between cold- and warm-incubated trout, we found that juvenile trout incubated as embryos at cold temperatures showed more swimming activity and took less time to initiate swimming for their size than those incubated in warm water. There were also body size and year effects but no effects of parental cross. For August, none of the incubation temperature effects observed in June persisted, but cold-incubated trout spent a larger proportion of their time motionless near the mirror than warm-incubated trout and there was a general body size effect on time to initiate swimming. The lack of any persistent effects of incubation temperature between June and August suggests that the effect is ephemeral. Notwithstanding, these results support the hypothesis that incubation temperature has short-term effects on activity of juvenile of brown trout during their first summer.

    Intensive Care Managers' Experiences of the COVID-19 Pandemic: A Dramatic Change of the Intensive Care Landscape2023In: Journal of Nursing Management, ISSN 0966-0429, E-ISSN 1365-2834, Vol. 2023, article id 3052994Article in journal (Refereed)
    Abstract [en]

    Aim. To describe intensive care managers' experiences of premises and resources of care in intensive care units during the COVID-19 pandemic. Background. Intensive care units (ICUs) were enormously pressured during the COVID-19 pandemic from many ill patients, requiring advanced care. Hospital and community volunteers increased staff strength. Obligatorily, recruitments were also conducted using transfer of staff from different hospital departments. However, there is little knowledge about intensive care managers' (ICMs) experiences of leadership during the COVID-19 pandemic. Methods. A qualitative descriptive study was conducted from March to April 2022. Semistructured interviews were held with 12 ICMs who were purposively sampled from the ICU in ten Swedish hospitals. Data were analysed using qualitative content analysis. Results. Two themes emerged: a dramatic change of the intensive care landscape and we could handle more than we thought, but at a steep price. Participants described that the ICUs had to perform extraordinary changes at a very fast pace, which initially created a sense of cohesion. Training and introduction to war-like conditions associated with uncertainty meant that ICMs had to support ICU staff in prioritising interventions. Participants described how ICUs stood strong against a pandemic, but stress, worries, and anxiety took a heavy toll on ICU staff and ICMs. The pandemic eroded the resilience in ICUs. Participants described a deterioration in health and said that sick leaves and resignations occurred. Conclusion. Our findings show ICMs' experiences as a field of tension between resources and demands, whereby the changes created a heavy burden that left intensive care weakened. Implications for Nursing Management. Findings emphasised the importance of creating working conditions using human resources and materials in order to rebuild resilience in intensive care with the ability to conduct safe patient care.

    Health Care Personnel's Perspectives on Quality of Palliative Care During the COVID-19 Pandemic - A Cross-Sectional2023In: Journal of Multidisciplinary Healthcare, ISSN 1178-2390, E-ISSN 1178-2390, Vol. 16, p. 2893-2903Article in journal (Refereed)
    Abstract [en]

    Purpose: The provision of high-quality palliative care is challenging, especially during a pandemic like COVID-19. The latter entailed major consequences for health care systems and health care personnel (HCP) in both specialist and community health care services, in Norway and worldwide. The aim of this study was to explore how the HCP perceived the quality of palliative care in nursing homes, medical care units, and intensive care units during the COVID-19 pandemic. Methods: This study had a cross-sectional design. A total of 290 HCP from Norway participated in the study (RR = 25.8%) between October and December 2021. The questionnaire comprised items concerning respondents' demographics and quality of care, the latter measured by the short form of the Quality from the Patient's Perspective-Palliative Care instrument, adapted for HCP. The STROBE checklist was used. Results: This study shows that the HCP scored subjective importance as higher in all dimensions, items and single items than their perception of the actual care received. This could indicate a need for improvement in all areas. Information about medication, opportunity to participate in decisions about medical and nursing care and continuity regarding receiving help from the same physician and nurse are examples of areas for improvement. Conclusion: Study results indicate that HCP from nursing homes, medical care units, and intensive care units perceived that quality of palliative care provided was not in line with what they perceived to be important for the patient. This indicate that it was challenging to provide high-quality palliative care during the COVID-19 pandemic.
