- The dynamics of individual flexible fibers in a turbulent flow field have been analyzed, varying their initial position, density and length. A particlelevel fiber model has been integrated into a general-purpose, open source Computational Fluid Dynamics (CFD) code. The fibers are modeled as chains of cylindrical segments connected by ball and socket joints. The equations of motion of the fibers contain the inertia of the segments, the contributions from hydrodynamic forces and torques, and the connectivity forces at the joints. Direct Numerical Simulation (DNS) of the incompressible Navier–Stokes equations is used to describe the fluid flow in a plane channel and a one-way coupling is considered between the fibers and the fluid phase. We investigate the translational motion of fibers by considering the mean square displacement of their trajectories. We find that the fiber motion is primarily governed by velocity correlations of the flow fluctuations. In addition, we show that there is a clear tendency of the thread-like fibers to evolve into complex geometrical configurations in a turbulent flow field, in fashion similar to random conformations of polymer strands subjected to thermal fluctuations in a suspension. Finally, we show that fiber inertia has a significant impact on reorientation time-scales of fibers suspended in a turbulent flow field.

- Introduction:The present article aimed to investigate 1) if mental health problems (depression and burnout including the dimensions; emotional exhaustion, mental distance and cognitive and emotional impairment) differed between nurses and physicians in Sweden, 2) if any differences were explained by differences in sex compositions, and 3) if any sex differences were larger within either of the two professions. Method:Data were derived from a representative sample of nurses (n = 2903) and physicians (n = 2712) in 2022. Two scales were used to assess burnout (KEDS and BAT) and one to assess depression (SCL-6). The BAT scale has four sub-dimensions. Descriptive statistics and logistic regression were used to analyse each scale and dimension separately. Results:Results showed that 16-28 % of nurses and physicians reported moderate to severe symptoms of burnout. The prevalence differed between occupations across the scales and dimensions used. Nurses reported higher scores on KEDS while physicians reported higher scores on BAT including the four dimensions. Also, 7 % of nurses' and 6 % of physicians' scores were above the cut-off for major depression. The inclusion of sex in the models changed the odds ratios of differences between doctors and nurses in all mental health dimensions except mental distance and cognitive impairment. Limitations: This study was based on cross-sectional survey data which has some limitations. Conclusion:Our study suggests that the prevalence of mental health problems is prominent among nurses and physicians in Sweden. Sex plays an important role in the difference in the prevalence of mental health problems between the two professions.

- This article explores equine-assisted social work (EASW). Horses' capacities to mirror human emotions create possibilities for authentic relationships between clients and staff. This study examines what eases or counteracts the horse's capacity to facilitate relationships perceived by humans to be authentic. Video recordings of the human-horse interactions of three staff members and four female self-harming clients aged 15–21 years in a residential treatment facility were analyzed. The findings show that if the staff gave instructions and advice similar to traditional equestrian sports in combination with viewing the horse as an object, EASW is not facilitated. EASW seems to be facilitated when the horse is perceived as a subject by both staff and clients, provided that the staff gave meaning to the horse's behavior. The staff needed to highlight empathy for the horse when the horse is not able to fulfill its task without adding depth to the client's performance, to avoid raising defense mechanisms. The essence of EASW were perceived as eased by staff members when they focus on the client's emotions and help the client understand that the horse is acting in response to the client's and the staff's behavior through mentalizing and enacting emotional labor in regarding the horse as a subject. The results indicate the need for higher demands on staff members in order to facilitate EASW. Depending on whether the staff and the clients focus on performance or on emotions, different positive or negative outcomes on communication, self-confidence, self-esteem, and self-image will be likely to emerge.

Tidskriftsartikel (refereegranskat)abstract
- Nanocomposites of metal nanoparticles (NPs) and bacterial nanocellulose (BC) enable fabrication of soft and biocompatible materials for optical, catalytic, electronic, and biomedical applications. Current BC-NP nanocomposites are typically prepared by in situ synthesis of the NPs or electrostatic adsorption of surface functionalized NPs, which limits possibilities to control and tune NP size, shape, concentration, and surface chemistry and influences the properties and performance of the materials. Here a self-assembly strategy is described for fabrication of complex and well-defined BC-NP composites using colloidal gold and silver NPs of different sizes, shapes, and concentrations. The self-assembly process results in nanocomposites with distinct biophysical and optical properties. In addition to antibacterial materials and materials with excellent senor performance, materials with unique mechanoplasmonic properties are developed. The homogenous incorporation of plasmonic gold NPs in the BC enables extensive modulation of the optical properties by mechanical stimuli. Compression gives rise to near-field coupling between adsorbed NPs, resulting in tunable spectral variations and enhanced broadband absorption that amplify both nonlinear optical and thermoplasmonic effects and enables novel biosensing strategies.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The study purpose was to describe the Swedish HealthPhys cohort. Using data from the HealthPhys study, we aimed to describe the prevalence of clinical burnout and major depression in a representative sample of Swedish physicians across gender, age, worksite, hierarchical position, and speciality in spring of 2021, during the third wave of the Covid-19 pandemic. Method: The HealthPhys questionnaire was sent to a representative sample of practising physicians (n = 6699) in Sweden in February to May of 2021 with a 41.3% response rate. The questionnaire included validated instruments measuring psychosocial work environment and health including measurements for major depression and clinical burnout. Results: Data from the HealthPhys study showed that among practising physicians in Sweden the prevalence of major depression was 4.8% and clinical burnout was 4.7%. However, the variations across sub-groups of physicians regarding major depression ranged from 0% to 10.1%. For clinical burnout estimates ranged from 1.3% to 14.5%. Emergency physicians had the highest levels of clinical burnout while they had 0% prevalence of major depression. Prevalence of exhaustion was high across all groups of physicians with physicians working in emergency departments, at the highest (28.6%) and anaesthesiologist at the lowest (5.6%). Junior physicians had high levels across all measurements. Conclusions: In conclusion, the first data collection from the HealthPhys study showed that the prevalence of major depression and clinical burnout varies across genders, age, hierarchical position, worksite, and specialty. Moreover, many practising physicians in Sweden experienced exhaustion and were at high risk of burnout.

Tidskriftsartikel (refereegranskat)abstract
- Despite the influence of stigmatization on vote choices, little attention has been given to the impact of social stigma on voters’ selection of voting procedures. To bridge this gap, our study focuses on Sweden, where the open-display ballot system at polling stations potentially compromises vote secrecy. Using survey data from the Swedish National Election Studies in 2014 and 2018, we examine the relationship between citizens’ voting procedure choices and their support for a highly stigmatized radical right party, the Sweden Democrats. Our findings reveal that voters of the Sweden Democrats are more inclined to vote in advance, particularly in districts with low general party support, indicating a high level of stigma. We argue that advance voting can be seen as a strategy to safeguard vote secrecy when voting for stigmatized parties within an institutional context featuring public displays of ballots. In addition, our research sheds light on the importance of electoral integrity in maintaining the confidentiality of voters’ choices.

Forskningsöversikt (refereegranskat)abstract
- Depression and anxiety are significant contributors to maternal perinatal morbidity and a range of negative child outcomes. This systematic review and meta-analysis aimed to review and assess the diagnostic test accuracy of selected screening tools (Edinburgh Postnatal Depression Scale [EPDS], EPDS-3A, Patient Health Questionnaire [PHQ-9]-, PHQ-2, Matthey Generic Mood Question [MGMQ], Generalized Anxiety Disorder scale [GAD-7], GAD-2, and the Whooley questions) used to identify women with antenatal depression or anxiety in Western countries.Material and methodsOn January 16, 2023, we searched 10 databases (CINAHL, Cochrane Library, CRD Database, Embase, Epistemonikos, International HTA Database, KSR Evidence, Ovid MEDLINE, PROSPERO and PsycINFO); the references of included studies were also screened. We included studies of any design that compared case-identification with a relevant screening tool to the outcome of a diagnostic interview based on the Diagnostic and Statistical Manual of Mental Disorders, fourth or fifth edition (DSM-IV or DSM-5), or the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10). Diagnoses of interest were major depressive disorder and anxiety disorders. Two authors independently screened abstracts and full-texts for relevance and evaluated the risk of bias using QUADAS-2. Data extraction was performed by one person and checked by another team member for accuracy. For synthesis, a bivariate model was used. The certainty of evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE). Registration: PROSPERO CRD42021236333.ResultsWe screened 8276 records for eligibility and included 16 original articles reporting on diagnostic test accuracy: 12 for the EPDS, one article each for the GAD-2, MGMQ, PHQ-9, PHQ-2, and Whooley questions, and no articles for the EPDS-3A or GAD-7. Most of the studies had moderate to high risk of bias. Ten of the EPDS articles provided data for synthesis at cutoffs >= 10 to >= 14 for diagnosing major depressive disorder. Cutoff >= 10 gave the optimal combined sensitivity (0.84, 95% confidence interval [CI]: 0.75-0.90) and specificity (0.87, 95% CI: 0.79-0.92).ConclusionsFindings from the meta-analysis suggest that the EPDS alone is not perfectly suitable for detection of major depressive disorder during pregnancy. Few studies have evaluated the other instruments, therefore, their usefulness for identification of women with depression and anxiety during pregnancy remains very uncertain. At present, case-identification with any tool may best serve as a complement to a broader dialogue between healthcare professionals and their patients. In this systematic review of 16 original articles, the Edinburgh Postnatal Depression Scale was the most frequently validated tool for identification of women with possible antenatal depression or anxiety. Our meta-analyses indicated a low pooled sensitivity, emphasizing the importance of combining questionnaire screening with other identification methods.

- This study investigated the association between diurnal salivary cortisol profile and perceived stress at work and at home. Healthy participants (N= 180, 52% women) collected saliva cortisol samples immediately after waking up, 15. min later, 30. min later, and at 9:00, 12:00, 15:00, 18:00 and 21:00. The area under the cortisol awakening curve with respect to ground (AUCgCAR) and increase (AUCiCAR), and diurnal slope between 9:00 and 21:00 were analyzed. Perceived stress at work and at home was measured with the Stress-Energy Questionnaire.Participants reporting stress at home had significantly lower AUCgCAR and a flatter diurnal slope. When performing separate analyses for men and women, this association was only significant among women. Perceived stress at work was not associated with any cortisol measure.This study highlights the importance of stress outside the workplace. The sex differences may indicate an increased vulnerability to non-work stress in women. © 2014 Elsevier B.V.

Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Det offentliga sociala arbetet befinner sig idag i ett tillstånd som innebär att det relationellt mänskliga, strukturella, förebyggande och lokalt förankrade sociala arbetet inte ges tid eller plats. Ett sådant offentligt socialt arbete får svårt att bidra till social förändring. Bokens författare, både forskare och praktiker, värnar ett visionärt socialt arbete som bygger på värderingar om social rättvisa och mänskliga rättigheter snarare än en organisering som bygger på värderingar om effektivisering, ekonomisering, individualisering och svenskhet.
