- When competition and an increasing level of marketisation characterises school life, the number of evaluations and the level of control has grown out of proportion. Through comparisons, assessments and ranking systems, also called ‘the terrors of performativity’ according to Ball (2003) commercial agents have gained influence over practices of assessment and documentation within the education system. Increased demands on pupils’ and parents’ participation and a belief that written documentation will lead to better results has caused an extensive use of different web based tools like Unikum. With the point of departure in a collected material of more than a hundred Individual Educations Plans (IEP) where commercial web based tools have been used, we make an analysis with Basil Bernstein’s (1996, 2000) concepts Pedagogic Identity, and Instructional and Regulative discourse in relation to expectations and constructions manifest in the plans. The results show that all four identities are expressed in the plans however, with an emphasis on a neo-liberal identity. We discuss the results in relation to the instructional and regulative discourses. The conclusion is that the tools both shape and determine possible identities and possible discourses in the web based interaction between children, parents and teachers.

- Biodeposits from farmed mussels severely influence the biogeochemistry of sediments by increasing the levels of organic matter (OM). Mitigation of such negative impacts is important for the development of sustainable aquaculture operations. As a step towards developing methods for remediation of coastal sediments affected by mussel farming, the effects of the polychaete, Hediste diversicolor was evaluated experimentally. In a series of field- and laboratory experiments we tested hypotheses about the effects of polychaetes on sediment oxygen consumption, nutrient fluxes and sulphide pools under different polychaete densities and sedimentation regimes. The experimental results support the idea that polychaetes can mitigate negative effects on the benthic environment beneath mussel farms. H.diversicolor oxidized the sediment and generally enhanced the oxygen consumption, and thus the decomposition of OM. The accumulation of pore water sulphides were reduced and fluxes of nutrients across the sediment-water interface increased. Additional calculations suggest that the effects of polychaetes were mainly indirect and driven by increased microbial activity due to the borrowing activity of the polychaetes. Trends of increasing decomposition with increasing polychaete density suggest that the decomposition could be further enhanced by higher densities. Overall, we concluded that H.diversicolor is a potentially strong candidate for remediation of mussel farm sediments. The results show that sediments inhabited by H.diversicolor have high assimilative capacity of OM and oxygen conditions are significantly improved following the addition of polychaetes at naturally occurring densities. However, technological developments are needed in order to allow the approach to be used in practice.

- PURPOSE: To develop a pelvic discomfort index (PDI) to evaluate outcome following fixation for pelvic ring injury.METHODS: 29 female and 44 male consecutive patients (mean age, 36 years) underwent internal fixation for pelvic ring injury of type B1 (n=10), B2 (n=22), B3 (n=15), C1 (n=18), C2 (n=5), and C3 (n=3), based on the AO/OTA classification. At postoperative 6, 12, and 24 months, patients were asked to assess their discomfort in the pelvis using a 14-item questionnaire. Three questions were open-ended, and responses were categorised by a single assessor. The remaining 11 questions were closed-ended and had 6 ordinal options from 'no discomfort' (score=0) to 'extremely severe discomfort' (score=5). The content validity and relevance of the 11 closed-ended questions was determined. The 14-item questionnaire was compared with the 36-item Short Form Health Survey (SF-36).RESULTS: Respectively at postoperative 6, 12, and 24 months, 78%, 71%, and 71% of the patients completed the 14-item questionnaire. Based on the factor analysis and responses to the open-ended questions, the number of items was reduced to 6 including pain, walking, mobility of the hips, loss of sensation in the legs, sexual life, and operation scar. Four factors could explain 96% of the total variance. The first factor involved the first 3 items (pain, walking, and hip motion) and addressed 'pelvis', whereas 3 factors involved the remaining items and each addressed peripheral neurology, sexual life, and operation scar. A PDI was developed using these 6 items. The PDI had high internal reliability (α=0.89), adequate content and criterion validity, and moderate correlation with the SF-36 total score or scores of physical function, bodily pain, and general health (r=0.50-0.77).CONCLUSION: The PDI provides valid, specific, and relevant information to assess outcome following fixation for pelvic ring injury.

Skadereducerande Effekt av Uppvärmda Trottoarer, Gång- och Cykelstråk
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Nearly two out of three fall crashes with seriously injured pedestrians occur in the winter (December-March), i.e. twice as many pedestrians are seriously injured during these four months compared to the rest of the year. During the winter period (December-March) almost nine out of ten fall crashes are caused in the traffic environment due to slipping on ice/snow.

Skadereducerande Effekt av Uppvärmda Trottoarer, Gång- och Cykelstråk - En Inledande Studie
- 2019
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Nästan två av tre fallolyckor med allvarligt skadade fotgängare sker under vintern; dubbelt så många fotgängare skadas allvarligt under dessa fyra månader jämfört med årets övriga. Under vinterperioden orsakas nästan nio av tio fallolyckor i trafikmiljö av halka pga is/snö. De skador som drabbar fotgängare (och cyklister) på halt underlag behöver i allmänhet betydligt längre vårdtid jämfört med om det inte varit halt. Det finns alltså en stor skadereducerande potential i förbättrad halkbekämpning. Syftet med studien är att: - Kartlägga uppvärmda ytor i stadsmiljön för de största städerna i Sverige - Analysera den skadereducerande effekten av uppvärmda ytor för fotgängare, och (om möjligt) cyklister.

- The effect of napping versus wakefulness was studied on primed and repeated Remote Associate Tests (RATs) and on divergent creativity tests. The participants were 42 students from the USA, studying international courses at a Swedish university. The hypotheses for the RATs were (1), when the correct answers were primed before the nap, the RAT should be solved better for those who entered REM sleep, compared to those with no REM sleep or a resting condition; and (2), when retested the RAT should be solved better after a nap than after rest. For the creativity tests, hypothesis (3) was that creativity should be higher after the nap than after rest. Hypothesis 1 and hypothesis 3 were not supported. Hypothesis 2 was supported in an ANOVA. The REM group improved more than the rest group on the repeated RAT. Also, the No-REM and rest groups differed, strengthening the importance of both REM and No-REM sleep for creative problem-solving.

- Differential treatment between trial arms has been suggested to bias prostate cancer (PC) mortality in the European Randomized Study of Screening for Prostate Cancer (ERSPC).To quantify the contribution of treatment differences to the observed PC mortality reduction between the screening arm (SA) and the control arm (CA).A total of 14 136 men with PC (SA: 7310; CA: 6826) in the core age group (55-69yr) at 16yr of follow-up.The outcomes measurements were observed and estimated numbers of PC deaths by treatment allocation in the SA and CA, respectively. Primary treatment allocation was modeled using multinomial logistic regression adjusting for center, age, year, prostate-specific antigen, grade group, and tumor-node-metastasis stage. For each treatment, logistic regression models were fitted for risk of PC death, separately for the SA and CA, and using the same covariates as for the treatment allocation model. Treatment probabilities were multiplied by estimated PC death risks for each treatment based on one arm, and then summed and compared with the observed number of deaths.The difference between the observed and estimated treatment distributions (hormonal therapy, radical prostatectomy, radiotherapy, and active surveillance/watchful waiting) in the two arms ranged from -3.3% to 3.3%. These figures, which represent the part of the treatment differences between arms that cannot be explained by clinicopathological differences, are small compared with the observed differences between arms that ranged between 7.2% and 10.1%. The difference between the observed and estimated numbers of PC deaths among men with PC was 0.05% (95% confidence interval [CI] -0.1%, 0.2%) when applying the CA model to the SA, had the two groups received identical primary treatment, given their clinical characteristics. When instead applying the SA model to the CA, the difference was, as expected, very similar-0.01% (95% CI -0.3%, 0.2%). Consistency of the results of the models demonstrates the robustness of the modeling approach. As the observed difference between trial arms was 4.2%, our findings suggest that differential treatment explains only a trivial proportion of the main findings of ERSPC. A limitation of the study is that only data on primary treatment were available.Use of prostate-specific antigen remains the predominant explanation for the reduction in PC mortality seen in the ERSPC trial and is not attributable to differential treatment between trial arms.This study shows that prostate cancer deaths in the European screening trial (European Randomized Study of Screening for Prostate Cancer) were prevented because men were diagnosed and treated earlier through prostate-specific antigen screening, and not because of different, or better, treatment in the screening arm compared with the control arm.

- Human innate lymphoid cells have been described to exist in different organs, with functional deregulation of these cells contributing to several disease states. Here, we performed the first detailed characterization of the phenotype, tissue-residency properties, and functionality of ILC1s, ILC2s, and ILC3s in the human adult and fetal liver. In addition, we investigated changes in the ILC compartment in liver fibrosis. A unique composition of tissue-resident ILCs was observed in nonfibrotic livers as compared with that in mucosal tissues, with NKp44− ILC3s accounting for the majority of total intrahepatic ILCs. The frequency of ILC2s, representing a small fraction of ILCs in nonfibrotic livers, increased in liver fibrosis and correlated directly with the severity of the disease. Notably, intrahepatic ILC2s secreted the profibrotic cytokine IL-13 when exposed to IL-33 and thymic stromal lymphopoetin (TSLP); these cytokines were produced by hepatocytes, hepatic stellate cells (HSCs), and Kupffer cells in response to TLR-3 stimulation. In summary, the present results provide the first detailed characterization of intrahepatic ILCs in human adult and fetal liver. The results indicate a role for ILC2s in human liver fibrosis, implying that targeting ILC2s might be a novel therapeutic strategy for its treatment.
