Institutional child sexual abuse is a concern for children, families, and society. Limited research has explored how school leaders and municipalities handle cases of sexual abuse in educational settings. This case study examines how a municipality managed the suspicion that 19 toddlers were sexually abused by an educator at several Early Childhood Education and Care institutions (ECEC). A nine-member crisis management team was formed that included key persons from the department of education and social welfare. During the initial phase of the investigation, only the team members were informed about the suspected abuse. In individual interviews, team members were asked how the team was organised and how their plans were implemented. In addition, they were asked about their experiences of participating in the crisis management. Three themes were identified: the set-up of the crisis management, the implementation of the crisis management plan, and important experiences. The crisis team emphasised that a child perspective rather than a general crisis perspective was applied and this approach was operationalised by key people in the educational and social welfare sectors. This paper highlights the impact of this case on the respondents as well as implications for the educational sector.
Purpose: Nurses’ lack of competence to be caring affects patients’ health and patients describe a desire for more individual and compassionate care. Nursing education tends, however, to focus less on the caring approach in nursing practice and more on developing knowledge in psychomotor skills. The aim of this study was to describe nursing students’ experiences of simulating caring and uncaring encounters founded on the caritative perspective at a Clinical Training Centre (CTC). Method: A qualitative, inductive approach using a qualitative latent content analysis. Written reflections of 49 students were analysed. Findings: By intertwining reflection with acting and observation, the students experienced that they achieved an open mind and gained an understanding of how important it was to treat the patient based on a caring approach. To act, first uncaring and thereafter caring, gave them an awakening. The students were touched and an overwhelming feeling of suddenly understanding human uniqueness and vulnerability appeared. Conclusions: To simulate caritative caring and uncaring encounters at the CTC enhanced students’ knowledge and understanding about caring and strengthened their prerequisites to acquire a caritative ontological basic view and attitude which in the long run may lead to an increased feeling of patient well-being in the encounter. © 2022 The Author(s).

Background Triage and triage related work has been performed in Swedish Emergency Departments (EDs) since the mid-1990s. The Rapid Emergency Triage and Treatment System (RETTS©), with annual updates, is the most applied triage system. However, the national implementation has been performed despite low scientific foundation for triage as a method, mainly related to the absence of adjustment to age and gender. Furthermore, there is a lack of studies of RETTS© in Swedish ED context, especially of RETTS© validity. Hence, the aim the study was to determine the validity of RETTS©. Methods A longitudinal retrospective register study based on cohort data from a healthcare region comprising two EDs in southern Sweden. Two editions of RETTS© was selected; year 2013 and 2016, enabling comparison of crude data, and adjusted for age-combined Charlson comorbidity index (ACCI) and gender. All patients ≥ 18 years visiting either of the two EDs seeing a physician, was included. Primary outcome was ten-day mortality, secondary outcome was admission to Intensive Care Unit (ICU). The data was analysed with descriptive, and inferential statistics. Results Totally 74,845 patients were included. There was an increase in patients allocated red or orange triage levels (unstable) between the years, but a decrease of admission, both to general ward and ICU. Of all patients, 1031 (1.4%) died within ten-days. Both cohorts demonstrated a statistically significant difference between the triage levels, i.e. a higher risk for ten-day mortality and ICU admission for patients in all triage levels compared to those in green triage level. Furthermore, significant statistically differences were demonstrated for ICU admission, crude as well as adjusted, and for adjusted data ten-day mortality, indicating that ACCI explained ten-day mortality, but not ICU admission. However, no statistically significant difference was found for the two annual editions of RETTS© considering ten-day mortality, crude data. Conclusion The annual upgrade of RETTS© had no statistically significant impact on the validity of the triage system, considering the risk for ten-day mortality. However, the inclusion of ACCI, or at least age, can improve the validity of the triage system. Graphical Abstract
Objective The objective of this paper is to describe the initial phase of a long-term collaboration initiative between a municipality and the Faculty of Medicine at a university in Sweden. The overall ambition of the collaboration is to strengthen the quality of care for older people. The concrete goal is to equip academically trained registered health care professionals (HCP) with tools for transferring evidence-based knowledge into practice. As municipal healthcare for older people is mainly carried out by staff lacking academic education, reg. HCP are key actors to bring in and consolidate an evidence-based approach in this setting. Developmental evaluation (DE) has been used to evaluate four separate activities in the initial phase. The activities where sequenced in a cumulative design to provide knowledge for further development of adequate tools. Results The cumulative design originally planned did not fit the internal logic of the municipality. Therefore, workflow and pace adjustments were made to proceed towards the joint ambition; the creation of fruitful conditions for the uptake of evidence-based knowledge. Long-term collaboration between academia and organizations outside academia demands a sensitive and flexible research approach, recognizing that collaboration implies mutuality and restricts the sovereignty of academia in designing research.
With the increased availability of timber materials, such as cross-laminated timber, the number of buildings using timber as a structural material has been rapidly increasing. As these buildings are new to the market, limited data and research on their long-term structural modal performance are available. This is particularly important in timber buildings since the material properties of wood are highly affected by environmental factors, especially the moisture content. Over time, the evolution of the dynamic properties is essential for damage indication in structural health monitoring systems since natural changes can mask the influence of damage. This work presents three years of observations from a structural monitoring system collecting data ever since completing a four-story timber-concrete hybrid building in Sweden. Ambient vibrations of the building were measured using geophones, resulting in 3,100 datasets. The temperature and relative humidity were measured both externally using a weather station and internally using sensors embedded in several walls and a slab in the building. The observed natural frequencies of the building vary with ± 0.2 Hz around the mean value over time. Linear regression analysis shows a significant correlation between the moisture content of a cross-laminated timber slab and the natural frequencies (coefficient of determination R2 up to 0.84). A predictive model for the natural frequencies is presented, taking seasonal variations and a dry-out of the structure into account. Variations from the expected values are ± 0.1 Hz at most. The model clearly narrows the error margins for damage indication in a structural health monitoring system.
We study links between Wick, anti-Wick and analytic kernel operators on the Bargmann transform side. We consider classes of kernels, whose corresponding operators agree with the sets of linear and continuous operators on spaces of power series expansions, which are Bargmann images of Pilipović spaces. We show that in several situations, the sets of Wick and kernel operators with symbols and kernels in such classes agree. We also find suitable subclasses to these kernel classes, whose corresponding sets of Wick and anti-Wick operators agree. We also show ring, module and composition properties for such classes.
There is a general consensus that private car ownership is a significant barrier to transport system change, specifically in regard to injuries, space, air pollutants, or greenhouse gas emissions. Observed changes in automobile characteristics also suggest that the system is becoming less sustainable, given trends towards larger cars with greater mass and horsepower. It is thus relevant to understand how the automobile system progresses. National statistics provide data on the technical side of car ownership, such as changes in vehicle specifics or national fleet size. This paper complements this view with a socio-psychological perspective on aspirational car ownership, i.e. the type of car people preferred to drive if given a free choice. Data is derived from an online panel (n = 1,211) representative of the German population, and also contains information on current car ownership, use, driving style, traffic behavior, attitudes towards traffic risks and safety measures, as well as political orientation. This allows for a discussion of driver segments in relation to the characteristics of cars, and hence to better understand the socio-psychological drivers of the development of the automobile system.
The chemical looping partial oxidation (CLPO) process as a technology of chemical looping process (CLP) is recognized as a potential strategy for the efficient and clean conversion of fuels into syngas/H2. Herein, in view of the importance of low-cost high-performance metal oxides as oxygen carriers (OCs) for this conversion, we systematically review the classification and CLPO applications of such OCs and discuss the improvement of OC reactivity and stability via the creation of metal–metal or metal–support synergism, the generation of oxygen vacancies, and the enhancement of deactivation resistance. Further, we present the results of theoretical and experimental characterizations probing ion diffusion and surface reactions to provide insights into the related reaction mechanisms and touch on the challenges and opportunities of developing metal oxides with excellent reactivity and long-term cycling stability in CLP. Thus, this review facilitates the design and performance regulation of OCs for future energy conversion systems.
Although previous studies have focused on companies that for some reason cease business operations, and on the ending of business relationships, less is known about once ceased business operations that are resumed at a later stage, embedded in the same or similar business network structures. Especially, there is little research on situations where prior relationships reappear in the process of resuming business operations. To fill this gap, the purpose of this paper is to elaborate on resuming of business operations after a hiatus, a certain period of “business inactivity”, and particularly on business network dynamics that can be influenced by reappearing prior relationships during the process of resuming business operations. Based on a single case study within the context of mining industry in Sweden, we add to the literature on business network dynamics by showing that resuming business operations implicates re-noding of a business network, involving both reappearing relationships as well as new relationships. Furthermore, our study operationalizes the concept of hiatus, showing that when resuming business operations, prior counterparts can act as gatekeepers, promoters, and facilitators that may hinder or support the resuming process.
Teaching methods and students’ preconceptions are considered a crucial basis for entrepreneurship education, not least when entrepreneurship is taught outside business schools with differentiated learning outcomes. This qualitative study seeks to explore students’ experiences of a visual-based teaching exercise––“Images of entrepreneurship”––and examines how the exercise contributes to making their preconceptions of entrepreneurship explicit. The study presents the exercise and its theoretical underpinnings and then, via interviews with 28 students from various educational backgrounds, gives a unique insight into their experiences of the exercise. The purpose is to contribute to the development of theory on pedagogical practices in classroom settings in entrepreneurship education in higher education. In order to systematically discuss the students’ relationship to the exercise and to their preconceptions of entrepreneurship, implicit theories are proposed and developed as a theoretical framework. Based on the students’ views, this study shows that entrepreneurship educators can use visual material to initiate reflective conversations about students’ implicit entrepreneurship theories, and involve students in evaluations of teaching methods in order to promote their perspective.
Skin microbiomes provide vital functions, yet knowledge about their species assemblages is limited - especially for non-model organisms. In this study, we conducted in situ manipulations and repeated sampling on wild-caught individuals of Rutilus rutilus. Treatments included translocation between fresh and brackish water habitats to investigate the role of environment; community rebooting by disinfection to infer host-microbe interactions; and housing in pairs to study the role of inter-host dispersal for the structure of microbiomes colonizing animals. Results revealed that fish skin microbiomes were biodiversity hotspots with highly dynamic composition that were distinct from bacterioplankton communities. External environmental conditions and individual-specific factors jointly determined the colonization-extinction dynamics, whereas inter-host dispersal had negligible effects. The dynamics of the microbiome composition was seemingly non-affected by reboot treatment, pointing to high resilience to disturbance in these microbial communities. Together, the manipulations demonstrate that host individual characteristics and environment interactively shapes the skin microbiome of fish. The results emphasize the role of inter-individual variability for the unexplained variation found in many host-microbiome systems, although the mechanistic underpinnings remain to be identified.
Background: Insomnia, sleep apnoea and sleep loss are risk factors for the development of cardiovascular diseases. Most research on sleep disturbances includes patients with heart failure, while the role of sleep in sudden cardiac arrest survivors (SCA) has been only partially investigated and understood. Sleep-related breathing disorders and obstructive sleep apnoea increase illness and mortality in the aftermath of SCA. Also, post-traumatic stress is evident in SCA survivors, where sleep disruptions are some of the main symptoms of the condition. Consequently, it is important to identify sleep problems in SCA survivors at an early stage to avoid unnecessary suffering. Purpose: The aim of this study was to investigate registered nurses' perceptions of SCA survivors' sleep, both in hospital and after discharge. Methods: This was an explorative interview study with a phenomenographic approach. Nineteen registered nurses (RNs) varying in age, sex and years in the profession participated. Findings: The nurses' perceptions of SCA survivors' sleep were categorized as: "The observer - noticing behaviours, emotions and habits of the patient that affect sleep", "The oblivious witness - attitudes that hinder the ability to recognise sleep behaviours", and "The practitioner - advising and medicating for sleep". The outcome space showed that the nurses detected both obvious and subtle signs relating to patients' sleep. However, attitudes hindering the recognition of sleep behaviours were independent of acting as an observer or practitioner. If nothing unforeseen was observed, or if the patient did not spontaneously raise the subject, sleep was considered less important than other health problems in SCA survivors. Conclusions: Although the nurses knew that SCA survivors suffered from poor sleep, they failed to reflect on the consequences for the patient. Nurses' feelings of insufficient knowledge about sleep, as well as their omittance of sleep in the follow-up documentation could leave sleep issues unaddressed and cause unnecessary patient suffering. Relevance to clinical practice: Nurses need increased knowledge and training to enable them to detect subtle signs of sleep problems in SCA survivors.
The use of actinides for medical, scientific and technological purposes has gained momentum in the recent years. This creates a need to understand their interactions with biomolecules, both at the interface and as they become complexed. Calculation of the Gibbs binding energies of the ions to biomolecules, i.e., the Gibbs energy change associated with a transfer of an ion from the water phase to its binding site, could help to understand the actinides' toxicities and to design agents that bind them with high affinities. To this end, there is a need to obtain accurate reference values for actinide hydration, that for most actinides are not available from experiment. In this study, a set of ionic radii is developed that enables future calculations of binding energies for Pu 3+ and five actinides with renewed scientific and technological interest: Ac 3+ , Am 3+ , Cm 3+ , Bk 3+ and Cf 3+ . Reference hydration energies were calculated using quantum chemistry and ion solvation theory and agree well for all ions except Ac 3+ , where ion solvation theory seems to underestimate the magnitude of the Gibbs hydration energy. The set of radii and reference energies that are presented here provide means to calculate binding energies for actinides and biomolecules.
