- In this study we analyze subject specific content in texts written in history education in school year 4 in a Swedish context. The study employs two different approaches to (text) content analysis: Analysis of representation of an historic vis-à-vis a practical perspective on the past, and analysis of the specific linguistic construals of the texts, based on a systemic functional linguistics approach. The results from the analyses are then compared to enable a synergetic account of the specific linguistic fabrics of the two historical perspectives. The results show that there are key differences in how the historical vis-à-vis the practical perspective on the past are linguistically construed, thus highlighting the intricacies of writing in history education. These findings are significant for researchers and teachers interested in furthering emergent historical literacy in early school years.

Tidskriftsartikel (refereegranskat)abstract
- Social anxiety disorder (SAD) can come in different forms, presenting problems for diagnostic classification. Here, we examined personality traits in a large sample of patients (N = 265) diagnosed with SAD in comparison to healthy controls (N = 164) by use of the Revised NEO Personality Inventory (NEO-PI-R) and Karolinska Scales of Personality (KSP). In addition, we identified subtypes of SAD based on cluster analysis of the NEO-PI-R Big Five personality dimensions. Significant group differences in personality traits between patients and controls were noted on all Big Five dimensions except agreeableness. Group differences were further noted on most lower-order facets of NEO-PI-R, and nearly all KSP variables. A logistic regression analysis showed, however, that only neuroticism and extraversion remained significant independent predictors of patient/control group when controlling for the effects of the other Big Five dimensions. Also, only neuroticism and extraversion yielded large effect sizes when SAD patients were compared to Swedish normative data for the NEO-PI-R. A two-step cluster analysis resulted in three separate clusters labelled Prototypical (33%), Introvert-Conscientious (29%), and Instable-Open (38%) SAD. Individuals in the Prototypical cluster deviated most on the Big Five dimensions and they were at the most severe end in profile analyses of social anxiety, self-rated fear during public speaking, trait anxiety, and anxiety-related KSP variables. While additional studies are needed to determine if personality subtypes in SAD differ in etiological and treatment-related factors, the present results demonstrate considerable personality heterogeneity in socially anxious individuals, further underscoring that SAD is a multidimensional disorder.

- Increasing the ionic conductivity has for decades been an overriding goal in the development of solid polymer electrolytes. According to fundamental theories on ion transport mechanisms in polymers, the ionic conductivity is strongly correlated to free volume and segmental mobility of the polymer for the conventional transport processes. Therefore, incorporating plasticizing side chains onto the main chain of the polymer host often appears as a clear-cut strategy to improve the ionic conductivity of the system through lowering of the glass transition temperature (T-g) This intended correlation between Tg and ionic conductivity is, however, not consistently observed in practice. The aim of this study is therefore to elucidate this interplay between segmental mobility and polymer structure in polymer electrolyte systems comprising plasticizing side chains. To this end, we utilize the synthetic versatility of the ion-conductive poly(trimethylene carbonate) (PTMC) platform. Two types of host polymers with side chains added to a PTMC backbone are employed, and the resulting electrolytes are investigated together with the side chain-free analogue both by experiment and with molecular dynamics (MD) simulations. The results show that while added side chains do indeed lead to a lower Tg, the total ionic conductivity is highest in the host matrix without side chains. It was seen in the MD simulations that while side chains promote ionic mobility associated with the polymer chain, the more efficient interchain hopping transport mechanism occurs with a higher probability in the system without side chains. This is connected to a significantly higher solvation site diversity for the Li+ ions in the side-chain-free system, providing better conduction paths. These results strongly indicate that the side chains in fact restrict the mobility of the Li+ ions in the polymer hosts.

- Oligonucleotide drugs represent an emerging area in the pharmaceutical industry. Solid-phase synthesis generates many structurally closely related impurities, making efficient separation systems for purification and analysis a key challenge during pharmaceutical drug development. To increase the fundamental understanding of the important preparative separation step, mass-overloaded injections of a fully phosphorothioated 16mer, i.e., deoxythymidine oligonucleotide, were performed on a C18 and a phenyl column. The narrowest elution profiles were obtained using the phenyl column, and the 16mer could be collected with high purity and yield on both columns. The most likely contribution to the successful purification was the quantifiable displacement of the early-eluting shortmers on both columns. In addition, the phenyl column displayed better separation of later-eluting impurities, such as the 17mer impurity. The mass-overloaded injections resulted in classical Langmuirian elution profiles on all columns, provided the concentration of the ion-pairing reagent in the eluent was sufficiently high. Two additional column chemistries, C4 and C8, were also investigated in terms of their selectivity and elution profile characteristics for the separation of 520mers fully phosphorothioated deoxythymidine oligonucleotides. When using triethylamine as ion-pairing reagent to separate phosphorothioated oligonucleotides, we observed peak broadening caused by the partial separation of diastereomers, predominantly seen on the C4 and C18 columns. When using the ion-pair reagent tributylamine, to suppress diastereomer separation, the greatest selectivity was found using the phenyl column followed by C18. The present results will be useful when designing and optimizing efficient preparative separations of synthetic oligonucleotides.

- Formalised knowledge systems, including universities and research institutes, are important for contemporary societies. They are, however, also arguably failing humanity when their impact is measured against the level of progress being made in stimulating the societal changes needed to address challenges like climate change. In this research we used a novel futures-oriented and participatory approach that asked what future envisioned knowledge systems might need to look like and how we might get there. Findings suggest that envisioned future systems will need to be much more collaborative, open, diverse, egalitarian, and able to work with values and systemic issues. They will also need to go beyond producing knowledge about our world to generating wisdom about how to act within it. To get to envisioned systems we will need to rapidly scale methodological innovations, connect innovators, and creatively accelerate learning about working with intractable challenges. We will also need to create new funding schemes, a global knowledge commons, and challenge deeply held assumptions. To genuinely be a creative force in supporting longevity of human and non-human life on our planet, the shift in knowledge systems will probably need to be at the scale of the enlightenment and speed of the scientific and technological revolution accompanying the second World War. This will require bold and strategic action from governments, scientists, civic society and sustained transformational intent.

- Purpose Since 2006, higher education institutions (HEIs) in Sweden, should according to the Higher Education Act, promote sustainable development (SD). In 2016, the Swedish Government asked the Swedish higher education authority to evaluate how this study is proceeding. The authority chose to focus on education. This paper aims to produce a report on this evaluation. Design/methodology/approach All 47 HEIs in Sweden were asked to write a self-evaluation report based on certain evaluation criteria. A panel was appointed consisting of academics and representatives for students and working life. The panel wrote an evaluation of each HEI, a report on general findings and recommendations, and gave an overall judgement of each HEI in two classes as follows: the HEI has well-developed processes for integration of SD in education or the HEI needs to develop their processes. Findings Overall, a mixed picture developed. Most HEIs could give examples of programmes or courses where SD was integrated. However, less than half of the HEIs had overarching goals for integration of SD in education or had a systematic follow-up of these goals. Even fewer worked specifically with pedagogy and didactics, teaching and learning methods and environments, sustainability competences or other characters of education for SD. Overall, only 12 out of 47 got a higher judgement. Originality/value This is a unique study in which all HEIs in a country are evaluated. This provides unique possibilities for identifying success factors and barriers. The importance of the leadership of the HEIs became clear.

- We investigate representations of mapping class groups of surfaces that arise from the untwisted Drinfeld double of a finite group G, focusing on surfaces without marked points or with one marked point. We obtain concrete descriptions of such representations in terms of finite group data. This allows us to establish various properties of these representations. In particular we show that they have finite images, and that for surfaces of genus at least 3 their restriction to the Torelli group is non-trivial iff G is non-abelian.

- AimsTo identify clusters based on graduating nursing students’ self‐reported professional competence and their achievement on a national examination. Furthermore, to describe and compare the identified clusters regarding sample characteristics, students’ perceptions of overall quality of the nursing programme and students’ general self‐efficacy.DesignA cross‐sectional study combining survey data and results from a national examination.MethodsData were collected at two universities and one university college in Sweden in January 2017, including 179 students in the final term of the nursing programme. The study was based on the Nurse Professional Competence Scale, the General Self‐Efficacy scale and results from the National Clinical Final Examination. A Two‐Step Cluster Analysis was used to identify competence profiles, followed by comparative analyses between clusters.ResultsThree clusters were identified illustrating students’ different competence profiles. Students in Cluster 1 and 2 passed the examination, but differed in their self‐assessments of competence, rating themselves under and above the overall median value respectively. Students in Cluster 3 failed the examination but rated themselves at the overall median level or higher.ConclusionThe study illustrates how nursing students’ self‐assessed competence might differ from competency assessed by examination, which is challenging for nursing education. Self‐evaluation is a key learning outcome and is, in the long run, essential to patient safety.ImpactThe study has identified clusters of students where some overestimate and others underestimate their competence. Students who assessed their competence low but passed the exam assessed their general self‐efficacy lower than other students. The findings illuminate the need for student‐centered strategies in nursing education, including elements of self‐assessment in relation to examination to make the students more aware of their clinical competence.

Tidskriftsartikel (refereegranskat)abstract
- Background Good nutrition is essential for individual health, a notion that is particularly true during pregnancy. We have used a nutrition index that measures the adequacy of one's diet relative to the unique nutritional needs of individuals due to, for example, their activity level, dietary restrictions, lifestyle and body size. The use of this personalised metric of dietary nutritiousness in the analysis of prenatal environmental exposures and developmental outcomes permits testing for potential mitigating effects of good nutrition. We also provide an analysis strategy for investigating the balance in beneficial food sources which are also the source of environmental toxicants. Methods A holistic measure of nutrition, My Nutrition Index (MNI), measures the nutrient quality (ie, 'nutritiousness') of a specified daily diet. MNI is calculated based on quantification of dozens of macronutrients and micronutrients that are specific to an individual's nutritional needs by incorporating dietary restrictions, subject characteristics, activity level and health behaviours. The Swedish Environmental, Longitudinal, Mother and child, Asthma and allergy Study is a Swedish pregnancy cohort, with prenatal endocrine disrupting chemicals (EDCs) exposure and dietary data available. This makes it possible to test for the potential mitigating effects of good nutrition on health and development effects in offspring from EDCs. Results Using prenatal Food Frequency Questionnaire data to construct an individual's MNI, the index was significantly and positively associated with important metabolic outcome (as measured by birth weight) and cognitive function at age 7 years (as measured by WISC IQ) in children when adjusted for covariates and prenatal concentrations of an EDC. In a stratified analysis of 'low' and 'high' fish consumption, a potential source of perfluoro-octanesulfonic acid (PFOS), the association between PFOS and birth weight was diminished in the high consumption group compared with the low consumption group. Conclusions Thus, MNI is evidently a metric of the general nutritiousness of daily diets and is useful in environmental health studies in representing the impact of good nutrition, even during pregnancy.

Tidskriftsartikel (refereegranskat)abstract
- As in most low-income countries, there is a lack of scientific information on the incidence and pattern of child maltreatment (CM) in Bangladesh. However, the role of the media to disclose CM and to develop public awareness in society is noteworthy. The present study assessed newspaper reports about CM by type and socio-demographics of victims and perpetrators in Bangladesh. In total, 790 news articles were collected retrospectively from four Bengali- and two English-language newspapers from October to December 2014. Among all reported incidents, almost half of the CM cases concerned alleged physical abuse (26%) and sexual abuse (22%). Neglect and emotional or psychological abuse received less coverage. Female children were to a high degree (90%) victims of sexual abuse. The main perpetrators were males, and they were often known to the victims. Approximately 32 per cent of the reported abuse cases resulted in death and were related to rape, family violence, administrative negligence, abduction and ransom demand. Some of these deaths were suicides. News stories concerning CM were often reported in an unethical way by identifying the victim and not respecting child rights. Further, the stories seldom discussed the individual or social consequences of CM, or how maltreatment could be prevented. 'The present study assessed newspaper reports about CM by type and socio-demographics of victims and perpetrators in Bangladesh' Key Practitioner Messages The main types of reported cases of CM in Bangladeshi print media are physical abuse and sexual abuse, and there is a high proportion of fatal consequences. The perpetrators are often known to the victims. The identity of the victim is frequently reported, potentially putting the child at risk and violating child rights. Bangladeshi print media seldom discusses individual or societal consequences of CM, or how it could be prevented.
