NARRATIVES , *CRITICAL analysis - Abstract
Megaprojects are vehicles of change and spatial products of policies from near and far. In this paper, we demonstrate how insights from the policy mobility literature can contribute to a critical analysis of the legitimization of megaprojects. Through a study of the planning of a new ‘world-class' hospital in Stockholm, we show that ideas, experiences and practices from abroad played a decisive role in legitimizing this megaproject. Policies mobilized from elsewhere were strategically used to construct, modify and (re)present a legitimizing narrative centred on the aspiration of excellence and international competitiveness. This narrative emphasized the need to transform both the spatial structure and the organization of the studied welfare institution based on political and value-based rationalities. Initial international references and ideas were adopted in an unstructured and selective manner, but proved enduring throughout the extensive planning process and were eventually consolidated into a coherent concept, effectively excluding alternative development paths. The vague notion of ‘world-class' functioned as a ‘magic concept’ that strengthened this narrative, rendering the project difficult to criticize. In conclusion, the paper emphasizes the importance of considering the temporal dimension of planning processes alongside the relational geographies of policy-mobility in megaproject analyses.

In this paper, we identify when and why migrant gig workers experience liminality in the socio-spatial context of food delivery in the Swedish gig economy. We analyse qualitative interviews and informal conversations with food delivery workers in Stockholm through the lens of the territory-place-scale-network (TPSN) framework as developed by Bob Jessop, Neil Brenner and Martin Jones. We find that workers are challenged to deal with triple liminality regarding their work identities, workplaces and work organisation through platforms. Focusing on liminality as a central aspect of gig work, we further find that despite having little worker agency, some of the study participants engage in what we call liminal agency, that is actively pursuing possibilities for progress in uncertain states of in-betweenness. By unpacking the liminal dynamics that especially migrant food delivery riders are confronted with in their daily working lives, this study contributes to the debate on the migrant gig economy, the spatial turn in organisation studies and efforts from human geography to understand agency in precarious gig work.

Measurements of electron-impact excitation and recombination rate coefficients of highly charged Si and S ions at the Stockholm electron beam ion trap are reported. The experimental method was a combination of photon detection from the trapped ions during probing and subsequently extraction and time-of-flight (TOF) charge analysis of these ions. The TOF technique allows to measure recombination rate coefficients separately for every charge state, and together with the photon spectra of these ions also the excitation rate coefficients. In this paper, we present more details of the experimental procedure and summarize the experimental results in comparison with two different state-of-the-art calculations of recombination and excitation rates for Si
10+ –Si13+ and S12+ –S15+ ions. One of these uses a relativistic configuration interaction approach (flexible atomic code) and the other is a relativistic many-body perturbation theory. A good to excellent agreement with both of them is found in energy and resonance strength for the investigated ions. [ABSTRACT FROM AUTHOR]- Published

The aim of this paper is to discuss the mobility of skilled labour within small and specialised guilds in peripheral Europe during the mid-seventeenth century. Based on archival records for passementerie makers and embroiderers in Stockholm, Sweden and Copenhagen, Denmark, the paper highlights conflicts brought on by labour mobility. What can these conflicts tell us about the situation within two small and specialised trades in Scandinavia, and how were they handled? The study examines examples of the actual implementation of both regulations and traditions associated with the crafts. This illuminates historical strategies for human resource management as well as economic relations between Scandinavia and the Continent. The results suggest a balancing act of negotiations between the needs of journeymen and masters respectively, paired with a pronounced need to align with their German counterparts. It also becomes clear that conditions differed between Stockholm and Copenhagen. Not only was the number of native artisans higher within the Danish guilds concerned, there was also substantial re-growth by apprenticeship. In contrast, Sweden was heavily dependent on immigration of skilled labour. [ABSTRACT FROM AUTHOR]

What characterizes the ideal urban futures that are envisioned and promulgated within smart city initiatives today? This paper argues for the usefulness of utopia as a lens to examine contemporary urban development projects, specifically smart cities. Drawing on scholars upholding utopianism as key for critical scholarship, the paper explores narratives around smartness in Stockholm, Sweden, and the utopian logics embedded within these narratives. Based on an in-depth case study in Stockholm, the research points to utopian logics of visibility , predictability and controllability within smart city initiatives. These further point to a common tendency where planning is sought perfected–and believed to approach perfection through the supplantation of human planners by smart technologies. As urban planning is faced with pressing urban challenges and dwindling resources, "mere" brain capacity largely appears as too limited and as necessary to compliment with computerized intelligence. • Using utopia as a lens, this paper explores the smart city initiative in Stockholm and the idealized futures it promotes. • Methodologically, the paper draws on extensive empirical research conducted using "Utopia as Method." • The paper points to "smart Stockholm" being characterized by utopian logics of visibility , predictability and controllability. • Together, these point to a tendency where planning is sought perfected through the integration of computerized intelligence.

Background: Women with mental illness experience an increased risk of cervical cancer. The excess risk is partly due to low participation in cervical screening; however, it remains unknown whether it is also attributable to an increased risk of infection with human papillomavirus (HPV). We aimed to examine whether women with mental illness had an increased infection rate of HPV compared to women without mental illness. Methods and findings: Using a cohort design, we analyzed all 337,116 women aged 30 to 64 and living in Stockholm, who had a negative test result of 14 high-risk HPV subtypes in HPV-based screening, during August 2014 to December 2019. We defined women as exposed to mental illness if they had a specialist diagnosis of mental disorder or had a filled prescription of psychotropic medication. We identified incident infection of any high-risk HPV during follow-up and fitted multivariable Cox models to estimate hazard ratios (HR) with 95% confidence intervals (CI) for HPV infection. A total of 3,263 women were tested positive for high-risk HPV during follow-up (median: 2.21 years; range: 0 to 5.42 years). The absolute infection rate of HPV was higher among women with a specialist diagnosis of mental disorder (HR = 1.45; 95% CI [1.34, 1.57]; p < 0.001) or a filled prescription of psychotropic medication (HR = 1.67; 95% CI [1.55, 1.79]; p < 0.001), compared to women without such. The increment in absolute infection rate was noted for depression, anxiety, stress-related disorder, substance-related disorder, and ADHD, and for use of antidepressants, anxiolytics, sedatives, and hypnotics, and was consistent across age groups. The main limitations included selection of the female population in Stockholm as they must have at least 1 negative test result of HPV, and relatively short follow-up as HPV-based screening was only introduced in 2014 in Stockholm. Conclusions: Mental illness is associated with an increased infection rate of high-risk HPV in women. Our findings motivate refined approaches to facilitate the WHO elimination agenda of cervical cancer among these marginalized women worldwide. Author summary: Why was this study done?: Mental illness has been associated with a higher risk of cervical cancer and precancerous lesions as well as a lower degree of participation in cervical screening. Little is known, however, regarding disparities in HPV infection between women with and without mental illness. What did the researchers do and find?: In a cohort study, we followed all 337,116 women who were at age 30 to 64, living in Stockholm, and had a negative test result of high-risk HPV during August 2014 to December 2019, to assess the link between mental illness and risk of infection with high-risk HPV. The absolute infection rate of HPV was 45% higher among women with a specialist diagnosis of mental disorder and 67% higher among women with a filled prescription of psychotropic medications, compared to women without such. What do these findings mean?: Mental illness is associated with an increased infection rate of oncogenic HPV in women. Refined approaches are needed to facilitate the elimination agenda of cervical cancer among women with mental illness. [ABSTRACT FROM AUTHOR]

After describing how the marine environment is tottering in the face of the triple environmental crisis, this article explores the limited governance progressions at the global and regional levels in addressing the threats of pollution, climate change and biodiversity loss in the especially vulnerable Arctic. For pollution, key limitations include slow and arduous processes to add chemicals for control under the Stockholm and Rotterdam Conventions and reliance at the regional level on a fragmented array of pollution studies and projects but without specific region-wide legally binding pollution standards. For climate change, the world is not on track to meet the Paris Agreement's temperature targets which is especially problematic for the Arctic cryosphere while the Arctic Council has largely been limited to providing general statements of concern and aspirational calls for enhanced climate mitigation and adaptation actions. For marine biodiversity losses, a pan-Arctic network of marine protected areas has yet to be developed and various implementation challenges surround the Agreement to Prevent Unregulated High Seas Fisheries in the Central Arctic Ocean including the need to ensure adequate financial, human resource and technical support. The paper concludes by highlighting some promising future governance directions. They include: the conclusion of a global treaty on plastic pollution; implementation of a new Global Framework on Chemicals – For a Planet Free of Harm from Chemicals and Waste; expected further clarifications from international tribunals on State responsibilities to address climate change; and regional implementation of the Kunming-Montreal Global Biodiversity Framework and the new agreement under the UN Convention on Law of the Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction.

Breast milk holds an immense nutritional value as it contains health-promoting substances in a unique, optimal form. Additionally, breast milk's significance extends to health and environmental protection, as it serves as an indicator of both maternal and infant exposure. In this study, breast milk samples collected in 2013 and in 2014–2016 from mothers in Vienna (Austria) were analysed for polybrominated diphenyl ethers (PBDE) and per- and polyfluoroalkyl substances (PFAS), as well as further substances which have been listed under the Stockholm Convention on Persistent Organic Pollutants (POPs) due to their persistent, bioaccumulative and toxic properties. The total concentration of the PBDE congeners in the samples (n = 18, sampled 2013) ranged from 0.055 to 52 ng/g lipid, and from 0.002 to 2.5 ng/g breast milk. In the pooled sample, the sum of PBDEs was detected at a level of 4.4 ng/g lipid. Based on the 2014–2016 study population, certain PFAS were detected in all samples (n = 40). Exposure to the sum of four specific PFAS including perfluorooctanesulphonate (PFOS), perfluorooctanoic acid (PFOA), perfluoro-n-nonanoic acid (PFNA) and perfluoro-1-hexanesulfonate (PFHxS) ranged between 0.014 and 0.12 ng/L breast milk. In the pooled sample, PFOS and PFOA were found in concentrations of 0.025 ng/g and of 0.045 ng/g, respectively. In addition, the first generation of POPs, mainly organochlorine compounds, was measured in a pooled sample of breast milk from participants sampled in 2014–2016 as part of the WHO/UNEP breast milk monitoring program and compared to the POPs measured in pooled samples collected in 1987/1988 and 1992/1993, respectively. Therefore, this paper demonstrates the effectiveness of the Stockholm Convention on POPs by comparing the Austrian results from the WHO/UNEP global breast milk study from 1987 to 2016. However, the data also show that, despite these reductions, health-relevant levels are still being reached, particularly in terms of children's health when the presence of the new generation of POPs, such as PBDEs and PFAS, in human breast milk is taken into account.

The instrument collection at the Royal Swedish Academy of Sciences houses a historically significant 10-foot achromatic refractor crafted by London instrument maker John Dollond. The telescope came into use at the Academy's Observatory in Stockholm in 1761 and remained in service into the 1820s. This paper aims to add to the biography of this instrument, encompassing its six decades of active service and, after 150 years in storage, its transformation into an exhibition showpiece. The paper begins by introducing the telescope, its maker and the conflict involving Dollond and the Swedish mathematician and physicist Samuel Klingenstierna over the discovery of the achromatic lens. This dispute ultimately resulted in the telescope finding its way to the Stockholm Observatory. Subsequently, the paper delves into how Academy astronomer Pehr Wargentin perceived and utilized this state-of-the-art refractor, along with brief mentions of its use by his successors. The final section narrates how the telescope ended up in the permanent exhibition of the Stockholm Observatory Museum. [ABSTRACT FROM AUTHOR]

The ambition to translate the concept of recovery capital (RC) from research to practice has entailed operationalisations of RC to measure progress and outcomes of alcohol and other drug (AOD) treatments.At the same time, the role played by standardisation in social work organisations is known to be a complex matter, and research suggests that the implementation of standardisation should be carried out with caution. By examining the need for a RC assessment tool in a Swedish AOD treatment context, this paper contributes to the discussion on the use of assessment tools for measuring treatment progress and outcome in AOD treatments, as well as interrelations between standardisation aims and social work professionals. Four group interviews with employees at AOD treatment facilities were conducted in Stockholm, Sweden. The interviewees were presented with an example of an RC-based assessment tool and asked to review the applicability of the tool in their daily work. The findings provide insights on the applicability of specific assessment list items, as well as general observations on the complex relationship between standardisation and discretion in social work. The findings suggest that professionals will ultimately rely on their knowledge and experience, and act accordingly to support the service user, regardless of any manual or standardisation that regulates their work.

As air pollution is regarded as the single largest environmental health risk in Europe it is important that communication to the public is up to date and accurate and provides means to avoid exposure to high air pollution levels. Long- and short-term exposure to outdoor air pollution is associated with increased risks of mortality and morbidity. Up-to-date information on present and coming days' air quality helps people avoid exposure during episodes with high levels of air pollution. Air quality forecasts can be based on deterministic dispersion modelling, but to be accurate this requires detailed information on future emissions, meteorological conditions and process-oriented dispersion modelling. In this paper, we apply different machine learning (ML) algorithms – random forest (RF), extreme gradient boosting (XGB), and long short-term memory (LSTM) – to improve 1, 2, and 3 d deterministic forecasts of PM 10 , NOx , and O 3 at different sites in Greater Stockholm, Sweden. It is shown that the deterministic forecasts can be significantly improved using the ML models but that the degree of improvement of the deterministic forecasts depends more on pollutant and site than on what ML algorithm is applied. Also, four feature importance methods, namely the mean decrease in impurity (MDI) method, permutation method, gradient-based method, and Shapley additive explanations (SHAP) method, are utilized to identify significant features that are common and robust across all models and methods for a pollutant. Deterministic forecasts of PM 10 are improved by the ML models through the input of lagged measurements and Julian day partly reflecting seasonal variations not properly parameterized in the deterministic forecasts. A systematic discrepancy by the deterministic forecasts in the diurnal cycle of NOx is removed by the ML models considering lagged measurements and calendar data like hour and weekday, reflecting the influence of local traffic emissions. For O 3 at the urban background site, the local photochemistry is not properly accounted for by the relatively coarse Copernicus Atmosphere Monitoring Service ensemble model (CAMS) used here for forecasting O 3 but is compensated for using the ML models by taking lagged measurements into account. Through multiple repetitions of the training process, the resulting ML models achieved improvements for all sites and pollutants. For NOx at street canyon sites, mean squared error (MSE) decreased by up to 60 %, and seven metrics, such as R2 and mean absolute percentage error (MAPE), exhibited consistent results. The prediction of PM 10 is improved significantly at the urban background site, whereas the ML models at street sites have difficulty capturing more information. The prediction accuracy of O 3 also modestly increased, with differences between metrics. Further work is needed to reduce deviations between model results and measurements for short periods with relatively high concentrations (peaks) at the street canyon sites. Such peaks can be due to a combination of non-typical emissions and unfavourable meteorological conditions, which are rather difficult to forecast. Furthermore, we show that general models trained using data from selected street sites can improve the deterministic forecasts of NOx at the station not involved in model training. For PM 10 this was only possible using more complex LSTM models. An important aspect to consider when choosing ML algorithms is the computational requirements for training the models in the deployment of the system. Tree-based models (RF and XGB) require fewer computational resources and yield comparable performance in comparison to LSTM. Therefore, tree-based models are now implemented operationally in the forecasts of air pollution and health risks in Stockholm. Nevertheless, there is big potential to develop generic models using advanced ML to take into account not only local temporal variation but also spatial variation at different stations.

This paper analyzes incomes and income inequality in Stockholm from 1870 to 1970. The paper builds on a new dataset of 38,022 randomly sampled Stockholm residents 1870–1950, with information on income, occupation, age, gender, and household composition. This is complemented by the Census of 1930 and a Statistics Sweden sample for 1960 and 1970. Incomes were very unequally distributed between 1870 and 1920, with Gini coefficients of pre-tax income around sixty. After 1920 inequality fell quite steadily. A drop in capital incomes contributed, and when looking at post-tax incomes the growth of progressive taxation after 1930 also contributed, but most of the high inequality up to 1920 and equalization after this date depended on the distribution of labour income. In the early 1900s professional groups had huge income advantages over workers, but this advantage was drastically reduced after 1920 when working-class incomes grew rapidly. An important mechanism of income growth was the upgrading of the jobs structure, highlighting the importance of structural change, beyond the Kuznetsian binary of agriculture–manufacturing, for understanding long-run economic inequality.

SEGREGATION in education ,SECONDARY education ,SCHOOL choice ,SIMULATION methods & models - Abstract
Previous studies investigating how the school choice paradigm shapes school segregation have found that students' ethnic school preferences drive school segregation by leading students to rank and change current schools following ethnic homophily orientations. This study investigates an intermediate moment in which these preferences contribute to the exacerbation of school segregation: students changing schools after being allocated to following admission rules but before the start of the academic year. We refer to these changes as micro-changes. Using Swedish register data on 9th-grade students applying to upper secondary education in Stockholm schools, this study evaluates how micro-changes affect school segregation. Our findings reveal that micro-changes are not neutral and increase school segregation levels because (1) students tend to reject of schools with a low share of in-group members and low representation of 9th-grade classmates, and (2) micro-changers move into schools with a high share of in-group members and 9th-grade classmates. Furthermore, our simulation model shows that micro-changes impact on school segregation have a cumulative effect. [ABSTRACT FROM AUTHOR]

Wood is considered to be one of the most important materials in the global economy. Wood loses shelf life in countries with severe winters. Pentachlorophenol (PCP) was predominantly used as a wood preservative because of its efficacy in controlling wood decay. This study discussed the overall impact of PCP across various environmental matrices, including soil, plants, water, air, and humans. Pentachlorophenol is a phenol substituted with five chloro-groups. High chlorination levels and stability of PCP make it hazardous to the environment, and persistent, and it also interferes with human, aquatic, and soil microbial health. PCP is volatile; thus, it is constantly discharged into the atmosphere and ingested by the human population. Owing to its hazardous nature, it was added to the Stockholm Convention's list of persistent organic pollutants (POPs) and phased out of the industry in 2023. This review has summarized PCP properties, usage, production volume, different transformation pathways, and its harmful effects on different environmental matrices such as air, water, soil, crops, and human health which have helped to outline the expected features of the new chemical compared with PCP. The improved chemical is intended to have quick degradability, fewer chlorine atoms, no aromatic structure, be non-toxic, environmentally benign, and efficient against wood deterioration while also penetrating the wood better.

Polychlorinated biphenyls (PCBs), including all 209 congeners, are designated as persistent organic pollutants (POPs) due to their high toxicity and bioaccumulation in human bodies and the ecosystem. The need for PCB remediation still remains long after their production ban. In this study, a catalytic hydro-dechlorination (HDC) method was employed to dechlorinate 2,4,4'-trichlorobiphenyl (PCB 28), a congener found ubiquitously in multiple environmental media. The HDC of PCB 28 was experimentally studied at mild temperatures viz. ~20, 50, and ~77°C and atmospheric pressure. Et
3 N (triethylamine) was added as a co-catalyst. The dechlorination rates increased with temperature as well as Et3 N dosage, and the HDC pathway was hypothesized based on the product and intermediates observed. The less chlorinated intermediates suggested that the position of the chlorine strongly impacted HDC rates, and the preference of HDC at para positions can be orders of magnitudes higher than the ortho. The activation energy was estimated in the range of 12.4–13.9 kJ/mole, indicating a diffusion-controlled HDC system. Implications: The remediation need for polychlorinated biphenyls (PCBs) still remains long after their production ban around the world. The development of low-cost methods is highly desirable, especially for developing countries, in response to the Stockholm Convention. In this study, the dechorination of a ubiquitously present PCB congener was studied using a catalytic hydro-dechlorination (HDC) method in low temperatures up to ~77°C and was able to achieve near 100% dechlorination in 6 hr. Results indicated that the HDC process can be performed under mild temperatures and atmospheric conditions and can be a potential solution to real world PCB contamination issues.

Background: Recent studies indicate that in-hospital exercise can mitigate the risk of functional decline in acutely hospitalized older adults. However, there is a lack of studies that compare different types of exercise interventions. This feasibility study was conducted in preparation for a three-armed randomized controlled trial. The aim was to examine the process feasibility (in terms of recruitment and retention rate, intervention compliance and acceptability), and scientific feasibility (in terms of presence of adverse events, and trends with 95% confidence intervals of the outcome measures) of the trial. Methods: Patients aged ≥75 years, were included from geriatric medical wards at three hospitals in Stockholm, Sweden. Participants in two groups received a specialized intervention program, i.e., Simple or Comprehensive exercise program, respectively and one group received usual care. Assessments were conducted at hospital admission and discharge, and data were analyzed with descriptive statistics. Results: In the spring 2022, 63 patients met the inclusion criteria and 39 accepted to participate (recruitment rate: 61.9%). COVID-19 affected the inclusion period. A total of 33 participants completed the study (i.e., were assessed at baseline and discharge, retention rate: 84.6%). Participants in the Simple and the Comprehensive exercise programs performed 88.9% and 80% of the possible training sessions, respectively. Both interventions were accepted by the participants and no adverse events were reported. The intervention groups showed a higher median change from admission to discharge than the control group on the Short Physical Performance Battery, the main outcome measure of the trial. Conclusion: The result of this pilot study suggests that the trial design is feasible and potentially useful for preventing functional decline in acutely hospitalized older adults. A full-scale trial will, however, require some considerations with respect to routines and logistics. The trial was registered at ClinicalTrials.gov, 4 May 2022, registration number NCT05366075.

Objectives: This qualitative study explored the perceptions of adult clients participating in a new psychological treatment for attention-deficit/hyperactivity disorder inattentive presentation (ADHD-I, also called "attention deficit disorder", ADD). The study aimed to explore (i) what aspects of treatment the participants found to be helpful, and (ii) if there were areas that ought to be developed to make the protocol more useful to clients with ADHD-I. Methods: Participants were recruited from treatment groups following the protocol of cognitive-behavioral therapy for ADHD-I (CADDI), at three psychiatric outpatient units in Stockholm, Sweden. Individual semi-structured interviews, lasting on average 44,6 minutes, were conducted with 14 adults after the completion of CADDI. Interviews explored participants' perceptions of CADDI, its usefulness, and asked for suggestions for improvement. Interviews were conducted by independent interviewers and were transcribed verbatim. The text was analyzed using reflexive thematic analysis. Results: The analysis generated three themes: "Factors of importance for change", with the subthemes; the group, therapeutic components, structure of treatment, and motivation,"Gains in treatment", with the subthemes; insight and understanding, increased attention, and planning and acting, and "Challenges with ADHD-I and remaining needs", with the subthemes; ADHD as a lifelong condition, maintaining gains in treatment, and wish for further support. Conclusions: Participants emphasized the importance of the group setting as a facilitator of therapeutic effects of increased understanding and self-acceptance. Further, they considered the practice of mindfulness to enhance attention and awareness of thoughts, feelings, and activities and considered the structure of treatment as supporting the work in therapy. These findings support the value of the group setting and confirm the usefulness of CADDI. However, participants were concerned about how to maintain gains of treatment after its termination and suggested follow-up sessions to improve the CADDI protocol. Trial registration: Preregistered at Clinical Trials: NCT05037903. [ABSTRACT FROM AUTHOR]

Introduction: Cultural and contextual factors affect communication and how psychiatric symptoms are presented, therefore psychiatric assessments need to include awareness of the patients' culture and context. The Cultural Formulation Interview (CFI) in DSM-5 is a person-centred tool developed to support the exploration of cultural and contextual factors in an individualized and non-stereotypic way. Methods: The aim of this qualitative study was to find out what information the DSM-5 CFI revealed when used with native Swedish-speaking patients as part of routine clinical psychiatric assessment at an outpatient clinic. An additional aim was to enhance understanding of what kind of information the questions about background and identity yielded. The CFI was added to the psychiatric assessment of 62 native Swedish-speaking patients at an outpatient psychiatric clinic in Stockholm. Results: From the thematic analysis of the documented CFI answers, six central themes were found; Descriptions of distress and dysfunction, Managing problems and distress, Current life conditions affecting the person, Perceived failure in meeting social expectations, Making sense of the problem, and Experiences of, and wishes for, help. The CFI questions about identity yielded much information, mainly related to social position and feelings of social failure. Discussion: For further refinement of the CFI, we see a need for re-framing the questions about cultural identity and its impact on health so that they are better understood. This is needed for majority population patients as direct questions about culture may be difficult to understand when cultural norms are implicit and often unexamined. For clinical implications, our findings suggest that for cultural majority patients the DSM-5 CFI can be a useful person-centred tool for exploring cultural and, in particular, social factors and patients' perception and understanding of distress.

Hexachlorobutadiene (HCBD) is a concerning chemical that is included in the United States Toxic Substances Control Act, and the Stockholm Convention. Knowledge of the sources of HCBD is insufficient and is pivotal for accurate inventory and implementing global action. In this study, unintentional HCBD release and source emission factors of 121 full-scale industrial plants from 12 industries are investigated. Secondary copper smelting, electric arc furnace steelmaking, and hazardous waste incineration show potential for large emission reductions, which are found of high HCBD emission concentrations of > 20 ng/g in fine particulate matter in this study. The highest HCBD emission concentration is observed for the secondary copper smelting industry (average: 1380 ng/g). Source emission factors of HCBD for the 12 industries range from 0.008 kg/t for coal fire power plants to 0.680 kg/t for secondary lead smelting, from which an estimation of approximately 8452.8 g HCBD emissions annually worldwide achieved. The carcinogenic risks caused by HCBD emissions from countries and regions with intensive 12 industrial sources are 1.0-80 times higher than that without these industries. These results will be useful for formulating effective strategies of HCBD control. Recognition on sources of hexachlorobutadiene is needed for their global control. This study clarifies hexachlorobutadiene emission factors from 121 industrial plants assigned to 12 industries and establishes their global emission inventory. [ABSTRACT FROM AUTHOR]

BREAST biopsy ,CONVOLUTIONAL neural networks ,ARTIFICIAL neural networks ,PROPORTIONAL hazards models - Abstract
Background: Nottingham histological grade (NHG) is a well established prognostic factor in breast cancer histopathology but has a high inter-assessor variability with many tumours being classified as intermediate grade, NHG2. Here, we evaluate if DeepGrade, a previously developed model for risk stratification of resected tumour specimens, could be applied to risk-stratify tumour biopsy specimens. Methods: A total of 11,955,755 tiles from 1169 whole slide images of preoperative biopsies from 896 patients diagnosed with breast cancer in Stockholm, Sweden, were included. DeepGrade, a deep convolutional neural network model, was applied for the prediction of low- and high-risk tumours. It was evaluated against clinically assigned grades NHG1 and NHG3 on the biopsy specimen but also against the grades assigned to the corresponding resection specimen using area under the operating curve (AUC). The prognostic value of the DeepGrade model in the biopsy setting was evaluated using time-to-event analysis. Results: Based on preoperative biopsy images, the DeepGrade model predicted resected tumour cases of clinical grades NHG1 and NHG3 with an AUC of 0.908 (95% CI: 0.88; 0.93). Furthermore, out of the 432 resected clinically-assigned NHG2 tumours, 281 (65%) were classified as DeepGrade-low and 151 (35%) as DeepGrade-high. Using a multivariable Cox proportional hazards model the hazard ratio between DeepGrade low- and high-risk groups was estimated as 2.01 (95% CI: 1.06; 3.79). Conclusions: DeepGrade provided prediction of tumour grades NHG1 and NHG3 on the resection specimen using only the biopsy specimen. The results demonstrate that the DeepGrade model can provide decision support to identify high-risk tumours based on preoperative biopsies, thus improving early treatment decisions.

Introduction: Team‐based learning (TBL) is a well‐established active teaching method which has been shown to have pedagogical advantages in some areas such as business education and preclinical disciplines in undergraduate medical education. Increasingly, it has been adapted to clinical disciplines. However, its superiority over conventional learning methods used in clinical years of medical school remains unclear. The aim of this study was to compare TBL with traditional seminars delivered in small group interactive learning (SIL) format in terms of knowledge acquisition and retention, satisfaction and engagement of undergraduate medical students during the 6‐week obstetrics and gynecology clerkship. Material and methods: The study was conducted at Karolinska Institutet, a medical university in Sweden, and had a prospective, crossover design. All fifth‐year medical students attending the obstetrics and gynecology clerkship, at four different teaching hospitals in Stockholm (approximately 40 students per site), in the Autumn semester of 2022 were invited to participate. Two seminars (one in obstetrics and one in gynecology) were designed and delivered in two different formats, ie TBL and SIL. The student:teacher ratio was approximately 10:1 in the traditional SIL seminars and 20:1 in the TBL. All TBL seminars were facilitated by a single teacher who had been trained and certified in TBL. Student knowledge acquisition and retention were assessed by final examination scores, and the engagement and satisfaction were assessed by questionnaires. For the TBL seminars, individual and team readiness assurance tests were also performed and evaluated. Results: Of 148 students participating in the classrooms, 132 answered the questionnaires. No statistically significant differences were observed between TBL and SIL methods with regard to student knowledge acquisition and retention, engagement and satisfaction. Conclusions: We found no differences in student learning outcomes or satisfaction using TBL or SIL methods. However, as TBL had a double the student to teacher ratio as compared with SIL, in settings where teachers are scarce and suitable rooms are available for TBL sessions, the method may be beneficial in reducing faculty workload without compromising students' learning outcomes.

Fifty years ago, the infamous bank robbery and ensuing hostage crisis that took place in a Stockholm bank gave rise to the so-called 'Stockholm syndrome'. Though never recognized as a valid medical diagnosis, the (allegedly) pathological relationship between kidnapper and hostage has become an omnipresent media phenomenon that inspires movies and television series to this day. However, this forced bond was not always seen as problematic. The years between 1860 and 1910 witnessed the rise of kidnappings in the Mediterranean world (Southern Italy, Greece, the Ottoman Balkan region, and Morocco) involving English, American, and European hostages. Today, we know about these incidents from autobiographical narratives by the former captives. They painted a surprisingly favourable picture of their captors – and found enthusiastic audiences for their stories. Looking at the interplay of feelings, coercion, and empowerment, the article opens up a new perspective on the history of emotions that brings both victims and perpetrators into the picture.

Background: Persistent, mobile and toxic (PMT), or very persistent and very mobile (vPvM) substances are a wide class of chemicals that are recalcitrant to degradation, easily transported, and potentially harmful to humans and the environment. Due to their persistence and mobility, these substances are often widespread in the environment once emitted, particularly in water resources, causing increased challenges during water treatment processes. Some PMT/vPvM substances such as GenX and perfluorobutane sulfonic acid have been identified as substances of very high concern (SVHCs) under the European Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation. With hundreds to thousands of potential PMT/vPvM substances yet to be assessed and managed, effective and efficient approaches that avoid a case-by-case assessment and prevent regrettable substitution are necessary to achieve the European Union's zero-pollution goal for a non-toxic environment by 2050. Main: Substance grouping has helped global regulation of some highly hazardous chemicals, e.g., through the Montreal Protocol and the Stockholm Convention. This article explores the potential of grouping strategies for identifying, assessing and managing PMT/vPvM substances. The aim is to facilitate early identification of lesser-known or new substances that potentially meet PMT/vPvM criteria, prompt additional testing, avoid regrettable use or substitution, and integrate into existing risk management strategies. Thus, this article provides an overview of PMT/vPvM substances and reviews the definition of PMT/vPvM criteria and various lists of PMT/vPvM substances available. It covers the current definition of groups, compares the use of substance grouping for hazard assessment and regulation, and discusses the advantages and disadvantages of grouping substances for regulation. The article then explores strategies for grouping PMT/vPvM substances, including read-across, structural similarity and commonly retained moieties, as well as the potential application of these strategies using cheminformatics to predict P, M and T properties for selected examples. Conclusions: Effective substance grouping can accelerate the assessment and management of PMT/vPvM substances, especially for substances that lack information. Advances to read-across methods and cheminformatics tools are needed to support efficient and effective chemical management, preventing broad entry of hazardous chemicals into the global market and favouring safer and more sustainable alternatives.

Leaf-cutting ants are the most important pests in several cropping systems in the Neotropics. Granulated baits containing active ingredients, considered hazardous by the Stockholm Convention, are the usual method to control these ants. Isocycloseram is a new insecticide molecule with high safety margin for mammals, but without registration for the ants in general. Thus, this study investigated the effectiveness of granulated baits with isocycloseram in leaf-cutting ants control under laboratory and field conditions. Initially, the mortality of Atta sexdens workers, fed with dehydrated citrus pulp paste containing different concentrations of isocycloseram was evaluated in the laboratory for 21 days, for toxicological classification. Subsequently, the loading, devolution, and incorporation of baits with different concentrations of isocycloseram and the mortality of A. sexdens colonies were evaluated in the laboratory. After that, the percentages of loading and devolution of baits, foraging activity, and colony mortality treated with 0.05, 0.1, 0.2, and 0.3% of isocycloseram were evaluated for the species A. sexdens, A. laevigata, and Acromyrmex lundii in field conditions. All concentrations of isocycloseram killed more than 15% of ants in 24 h and more than 90% in 21 days in the laboratory, being classified as a fast-acting and highly effective active ingredient. Baits with 0.001 to 0.03% of isocycloseram were highly loaded and exhibited low rate of devolution. The mortality of A. sexdens colony was higher at concentrations between 0.075 and 0.3%, in the laboratory. Baits containing isocycloseram at concentrations of 0.2 and 0.3% were highly loaded, presented low devolution rates, and were highly efficient in controlling A. sexdens, A. laevigata, and A. lundii in the field, at dosages of 6, 10, and 12 g/m² of nest. This is the first report of the use of isocycloseram against leaf-cutting ants, contributing to the development of efficient and toxicologically safer ant baits. [ABSTRACT FROM AUTHOR]

Background: Urban green spaces are important for human health, but they may expose visitors to tick-borne diseases. This not only presents a potential public health challenge but also undermines the expected public health gains from urban green spaces. The aim of this study is to assess the public health risk of tick-borne diseases in an urban green space used for recreation in Stockholm, Sweden. Methods: We used a mixed method approach identifying both the magnitude of the tick hazard and the extent of the human exposure to tick-borne diseases. At six entry points to an urban green space, we sampled ticks and documented microhabitat conditions from five randomly assigned 2 m × 2 m plots. Surrounding habitat data was analyzed using geographical information system (GIS). Nymphs and adult ticks were tested for Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum using TaqMan qPCR. Positive B. burgdorferi (s.l.) ticks were further analyzed by nested PCR amplification and sequence analysis. Population census data and visitor count data were used to estimate the degree of human exposure to tick-borne diseases. To further understand the degree to which visitors get in contact with infected ticks we also conducted interviews with visitors to green spaces. Results: High tick densities were commonly found in humid broadleaved forest with low field vegetation. High pathogen prevalence was significantly correlated with increasing proportions of artificial areas. Integrating the tick hazard with human exposure we found that the public health risk of tick-borne diseases was moderate to high at most of the studied entry points. Many of the visitors frequently used urban green spaces. Walking was the most common activity, but visitors also engaged in activities with higher risk for tick encounters. Individual protective measures were connected to specific recreational activities such as picking berries or mushrooms. Conclusions: The number of visitors can be combined with tick inventory data and molecular analyses of pathogen prevalence to make crude estimations of the public health risk of tick-borne diseases in urban green spaces. The risk of encountering infected ticks is omnipresent during recreational activities in urban green spaces, highlighting the need for public health campaigns to reduce the risk of tick-borne diseases.

Background: Digital health care services have the potential to improve access to sexual and reproductive health care for youth but require substantial implementation efforts to translate into individual and public health gains. Health care providers are influential both regarding implementation and utilization of the services, and hence, their perceptions of digital health care services and the implementation process are essential to identify and address. The aim of this study was to explore midwives' perception of digital sexual and reproductive health care services for youth, and to identify perceived barriers and facilitators of the implementation of digital health care provision in youth clinics. Methods: We performed semi-structured interviews with midwives (n = 16) working at youth clinics providing both on-site and digital sexual and reproductive health care services to youth in Stockholm, Sweden. Interview data were analyzed using a content analysis approach guided by the Consolidated Framework for Implementation Research (CFIR). Results: Midwives acknowledged that the implementation of digital health care improved the overall access and timeliness of the services at youth clinics. The ability to accommodate the needs of youth regarding their preferred meeting environment (digital or on-site) and easy access to follow-up consultations were identified as benefits of digital health care. Challenges to provide digital health care included communication barriers, privacy and confidentiality concerns, time constraints, inability to offer digital appointments for social counselling, and midwives' preference for in person consultations. Experiencing organizational support during the implementation was appreciated but varied between the respondents. Conclusion: Digital sexual and reproductive health care services could increase access and are valuable complements to on-site services in youth clinics. Sufficient training for midwives and organizational support are crucial to ensure high quality health care. Privacy and safety concerns for the youth might aggravate implementation of digital health care. Future research could focus on equitable access and youth' perceptions of digital health care services for sexual and reproductive health. [ABSTRACT FROM AUTHOR]

• Stockholm municipality currently lacks a long-term underground plan or strategy. • Stockholm's subsurface has significant potential for underground urban use. • The city faces many challenges in adopting a comprehensive and long-term strategy. With an expected increase in urbanisation and low-carbon transition efforts, the planning of cities is becoming more challenging, and societies need to rethink how urban infrastructures will be constructed in the future. There is a growing recognition that the use of space below the city will need to be significantly enhanced. However, once transformed, underground space becomes a permanent feature, and major metropolitan areas worldwide are gradually acknowledging the subsurface as a valuable, non-renewable resource, emphasising the necessity for long-term, comprehensive, and sustainable planning of its utilisation. Sweden, including the Stockholm region, has favourable geological conditions for building underground facilities and a long tradition of subsurface engineering. Despite these advantages, Stockholm lacks a comprehensive, long-term underground plan or strategy. For years, major subsurface projects have been driven by short-term needs, potentially hindering the optimal use of space below the cityscape. The overall purpose of this paper is twofold. First, we explore the nascent area of scholarly work concerned with the case of Stockholm's subsurface. We do so by evaluating the current status and potential of urban underground planning in Stockholm municipality. Second, we seek to advance existing planning knowledge and practices concerning Stockholm's subsurface by identifying several distinct but interrelated gaps and challenges that impede the immediate integration of urban underground space into strategic decision-making for the future of underground planning in Stockholm. We suggest that further research is necessary in several key areas to facilitate the effectiveness and sustainability of long-term urban underground use and planning in Stockholm City and its metropolitan area.

[Display omitted] • PVs that can be mobilized in the north–south hemispheres is proposed for the first time. • Foldable PVs bracket is designed for easy PVs transportation. • Locations at different latitude are chosen for case study. • Results show that the mobilized PVs deployed in high latitudes has favorable performance. Due to seasonal changes, photovoltaic systems in some areas may remain idle for a long period of time. In order to improve the utilization efficiency and working hours of photovoltaic systems, this paper proposes a concept of a mobilized photovoltaic system which can be transferred between different locations. Based on this idea, a foldable and removable photovoltaic module is designed. To validate the feasibility of the proposed mobilized photovoltaic system, two cases with transferring routes between Stockholm and Rio Grande (representing high latitude regions, Case 1) and between Rabat and Cape Town (representing mid and low latitude regions, Case 2) are selected. For Case 1, the annual power generation of mobilized photovoltaic systems is 169 MWh and 195 MWh higher than that of the fixed photovoltaic systems (PVs) deployed at Stockholm and Rio Grande. For Case 2, the annual power generation of mobilized PVs are lower than that of the fixed PVs deployed at Rabat and Cape Town. In addition, the levelized cost of electricity of the mobilized photovoltaics is 0.074 $/kWh and 0.099 $/kWh lower than that of the fixed photovoltaics in Case 1. However, the levelized cost of electricity of the mobilized photovoltaics in Case 2 is 0.011 $/kWh higher that of the fixed photovoltaics. The analysis results indicate that deploying transferable PV between high latitude regions in the northern and southern hemispheres has good technical and economic benefits. [ABSTRACT FROM AUTHOR]

Background: Research is lacking on predictors of outcome for the treatment of alcohol use disorder (AUD) with a goal of controlled drinking (CD). The aim of the study was to investigate one-year outcomes of an RCT, investigating Behavioral Self-Control Training (BSCT) and Motivational Enhancement Therapy (MET) and predictors of positive outcome for weekly alcohol consumption, CD and symptom reduction in AUD. Methods: This study is based on secondary analyses from a randomized controlled trial including 250 individuals with AUD (52% men) recruited from three specialized addiction clinics in Stockholm, Sweden. Linear and logistic mixed regression models were used for outcomes at 52 weeks, and linear and logistic regression models for the predictor analyses. Results: BSCT was superior to MET for the change between baseline to 52 weeks for the outcome of CD, defined as low-risk drinking below ten standard drinks per week for both genders (p = 0.048). A total of 57% of individuals in BSCT attained a level of CD, as opposed to 43% in MET. Females were significantly better in attaining low-risk drinking levels compared to men. The predictor for obtaining CD and reducing weekly alcohol consumption, was a lower baseline alcohol consumption. Predictors of symptom reduction in AUD were lower baseline level of AUD, and a lower self-rated impaired control over alcohol consumption. Conclusions: BSCT was superior to MET in obtaining CD levels, and women were superior to men for the same outcome. The study corroborated baseline consumption levels as an important predictor of outcome in CD treatments. The study contributes with important knowledge on key treatment targets, and knowledge to support and advice patients in planning for treatment with a goal of controlled drinking. Trial registration: The original study was registered retrospectively at isrtcn.com (14539251). [ABSTRACT FROM AUTHOR]

Cities around the world are trying to understand if and how to regulate urban mobility in a way that stimulates innovation and supports business while also promoting public values and accelerating a sustainability transition. Service providers are also attempting to understand how to grow and thrive as a business as they challenge existing urban mobility structures and practices via new mobility services, new uses of public space, etc. Thus, this article seeks to understand the interplay between business models and public policies and, ultimately, the implications policy instruments have on shaping conditions for sustainable urban mobility. To address these questions, a qualitative approach is utilized, comprising case studies of two 'new mobility' service providers (Bolt and Tier) operating in three Northern European cities (Oslo, Stockholm, and Berlin) including interviews with these companies and local public actors. Findings show that the business models are influenced by legitimization on the national level, the local authorities' and service providers' approaches, and policy instruments related to the right to operate, including caps, geographic coverage, parking, geofencing, and data sharing. Utilizing business models and multi-level perspectives, the findings are discussed in relation to actualizing sustainable transport, e.g. interdependencies, goal alignment, and temporal and spatial considerations. The authors emphasize the importance of learning by doing, policy mixes (versus instruments), and purpose-driven collaboration among stakeholders. [ABSTRACT FROM AUTHOR]

OLDER people - Abstract
Background: Delayed neurocognitive recovery and neurocognitive disorder are common postoperative complications among older adults. The assessment of these complications traditionally relies on analog neurocognitive tests, predominantly using the test battery from the ISPOCD-study as the standard approach. However, analog tests are time-consuming and necessitate trained staff which poses limitations. The potential availability of a digital neurocognitive test as an alternative to the ISPOCD remains unknown. We conducted a comparative study between the analog test battery from ISPOCD and the self-administrated digital test battery developed by Mindmore. Methods: We conducted a crossover study with 50 cognitively healthy older adults ≥ 60 years of age recruited in Stockholm Sweden, between February and April 2022. The primary outcome focused on measuring comparability between the two test batteries. Our secondary outcomes included assessing participants' perceptions and attitudes about the tests with qualitative interviews and their usability experiences. Results: Fifty older adults, mean age 76, female 56%, with a university or college degree 48% participated in the study. The sub tests in two test batteries demonstrated a medium–large correlation (r = 0.3–0.5), except for one measure. For four out of six measures, significant differences were found with medium to large effect sizes, ranging from 0.57–1.43. Two categories were recognized in the qualitative analysis: self-competing in a safe environment, and experience with technology. Participants expressed feeling safe and at ease during the assessment, with some preferring the digital test over the analog. Participants reported a high level of usability with the digital test and a majority participants (n = 47) reported they would undergo the digital test for a potential future surgery. Conclusions: The digital test battery developed by Mindmore offers several advantages, including rapid access to test results, easy comprehension, and use for participants, thereby increased accessibility of cognitive screening.

Introduction: Fetal growth restriction (FGR) is associated with increased risk for stillbirth, perinatal morbidity, cerebral palsy, neurodevelopmental disorders and cardiovascular disease later in life. Identifying small‐for‐gestational‐age (SGA) fetuses is crucial for the diagnosis of FGR. The aim of this study was to investigate the association between antenatal identification of SGA fetuses and severe adverse perinatal and childhood outcome. Material and methods: A register‐based cohort study of all newborns delivered in Stockholm in 2014 and 2017. Inclusion criteria: singleton pregnancies without chromosomal aberrations or structural abnormalities, with a gestational age at delivery between 22+0 and 43+0 (n = 48 843). Data from childbirth records were linked to data from nationwide Swedish registers. Pregnancy including offspring data were reviewed. Adverse outcomes for non‐identified and identified SGA newborns were compared using logistic regression models. Primary outcome was a composite outcome called severe adverse outcome, defined as at least one of the following: stillbirth, severe newborn distress (Apgar score <4 at 5 min, pH <7 or resuscitation activities >10 min), severe neonatal outcome (hypoxic ischemic encephalopathy 2–3, necrotizing enterocolitis, neonatal seizures, intraventricular hemorrhage grade 3–4, bronchopulmonary disease or death at <1 year), severe childhood outcome (cognitive impairment or motor impairment or cerebral palsy or hearing impairment or visual impairment or death at 1–3 years old). Secondary outcomes were stillbirth, severe newborn distress, severe neonatal outcome, severe childhood outcome. Results: No association was found between antenatal identification of SGA fetuses and severe adverse outcome using the complete composite outcome (adjusted odds ratio [aOR] 1.19, 95% confidence interval [CI] 0.93–1.53). In subgroup analyses, non‐identified SGA fetuses had an almost fivefold increased risk for stillbirth (aOR 4.79, 95% CI 2.63–8.72) and an increased risk for severe newborn distress (aOR 1.36, 95% CI 1.02–1.82), but a decreased risk for severe childhood outcome (aOR 0.63, 95% CI 0.40–0.99). No association was found between antenatal identification of SGA and severe neonatal outcome. Conclusions: Non‐identified SGA fetuses have an increased risk for stillbirth and severe newborn distress. Conversely, identified SGA fetuses have an increased risk for severe childhood outcome.

Introduction: The incidence of stillbirth in Sweden has started to decline. However, some comparable high‐income countries in Europe have an even lower incidence, indicating a potential for further reduction. The aim of our study was to investigate how the incidence of stillbirth for singleton pregnancies has changed over the past two decades in the Stockholm Region in different groups of women to detect the groups at highest risk. Material and methods: This was a repeated cross‐sectional study with data from the Stockholm Stillbirth Database and the Pregnancy Register including all cases of stillbirth in Stockholm in singleton pregnancies between 2001 and 2020, in total 1804 stillbirths. The time period was divided into four equal groups and the incidence of stillbirth was compared between the groups. Results: The overall incidence of stillbirth in the Stockholm Region has decreased from 3.8/1000 births in 2001–2005 to 2.9/1000 births in 2016–2020 (P‐value <0.001). In most of the groups studied, the incidence decreased, but among women originating from sub‐Saharan Africa the incidence significantly rose from 7.9/1000 births in 2001–2005 to 10.1/1000 births in 2016–2020 (P‐value 0.025). In this group, stillbirth occurred prematurely to a higher extent and the women were more likely to be multiparous. Conclusions: The incidence of stillbirth in the Stockholm Region has declined. However, among women originating from sub‐Saharan Africa the incidence was significantly higher compared with women originating from other regions and it is still rising. More research is needed to understand why this group is at higher risk and how to monitor their pregnancies to decrease this risk. [ABSTRACT FROM AUTHOR]

This study aims to develop an optimization strategy for determining the optimal type and capacity of batteries in a building‐applied photovoltaic system, taking into account battery degradation, consumption profiles, and regional solar irradiation. Key performance indicators such as peak shaving, savings, net present value, self‐consumption, return on investment, and payback period are examined. The best trade‐off among these indicators is determined using the fuzzy decision‐making method. A study was conducted using real data from Kpenergy Company, focusing on a building with a 50 kW photovoltaic system located in Stockholm. Three cases were examined in MATLAB software, each categorized based on the type of contract between the utility (Vattenfall Company) and the subscriber. The results of these case studies highlight the effectiveness of the proposed optimization approach. Using the proposed approach, optimal batteries are determined, minimizing subscriber costs while maximizing profit. [ABSTRACT FROM AUTHOR]

DEMENTIA ,MEDICAL care ,CENTRAL nervous system diseases - Abstract
A recent study conducted in Stockholm, Sweden explored the benefits of co-produced meeting centers for individuals with newly diagnosed dementia. The researchers found that these centers provided a space for human connection, a break from daily life, and an opportunity to share knowledge and develop new skills. Challenges were also identified, but overall, co-production was seen as a way to address the needs of people with dementia and reduce stigma. The study suggests that further research is needed to develop co-production services in regions where support for newly diagnosed individuals with dementia is lacking. [Extracted from the article]
