Att kunna lyssna med kroppen : En studie av gestaltande förmåga inom gymnasieskolans estetiska program, inriktning teater

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Theatre has been a school subject in the Swedish upper secondary school's national arts program since 1992 and has its own syllabus and grading criteria. The National Curriculum in theatre emphasises the development of performative capability, which is the focus of this dissertation. This study aims to contribute to the improvement of teachers’ subject-specific language, and concerns certain aspects of student ways of knowing.Theatre encompasses tacit knowledge (Lagerström 2003) and as an art form belongs to a tradition of practical knowledge. Knowledge in theatre has traditionally been acquired within a master-apprentice tradition (Johansson 2012, Järleby 2003). When theatre as an art form becomes a school subject the conditions of the art form change through a didactic transposition (Chevallard 2005). The previous two curriculum reforms in Sweden have developed competency-based syllabuses. To meet the school's requirements for planning teaching activities with colleagues as well as assessing and giving feedback to students, theatre knowledge needs to be articulated. Research is therefore needed to develop a professional language among teachers within the subject of theatre.I have chosen to work with Learning study, which is a collaborative and iterative research approach which enables the articulation of teachers and students knowing. Data is analysed using foremost phenomenographic analyses. The results generated in this study could be useful for teachers in the process of planning lessons, giving feedback to students, for assessments and grades, for discussing the content of lessons with other teachers, and ultimately for us to begin to recognize different levels of knowing.

- Backbone N-methylated peptide nucleic acids (PNAs) containing the four nucleobases adenine, cytosine, guanine and thymine were synthesized via solid phase peptide oligomerization. The oligomers bind to their complementary target with a thermal stability that is 1.5-4.5 degrees C lower per "N-methyl nucleobase unit" [dependent on the number and position(s) of the N-methyl] than that of unmodified PNA. However, even fully N-methyl modified PNAs bind as efficiently to DNA or RNA targets as DNA itself. Furthermore, the hybridization efficiency per N-methyl unit in a PNA decreased with increasing N-methyl content, and the effect was more pronounced when the N-methyl backbone units are present in the Hoogsteen versus the Watson-Crick strand in (PNA)(2)-DNA triplexes. Interestingly, CD spectral analyses indicate that 30% (3 out of ten) substitution with N-methyl nucleobases did not alter the structure of PNA-DNA (or RNA) duplexes or (PNA)(2)-DNA triplexes, and likewise CD spectroscopy and X-ray crystallography showed no major structural differences between N-methylated (30%) and unmodified PNA-PNA duplexes. However, PNA-DNA duplexes as well as triplexes adopted a different conformation when formed with all-Ai-methyl PNAs.

Early prediction of blood stream infection in a prospectively collected cohort

- BACKGROUND: Blood stream infection (BSI) and sepsis are serious clinical conditions and identification of the disease-causing pathogen is important for patient management. The RISE (Rapid Identification of SEpsis) study was carried out to collect a cohort allowing high-quality studies on different aspects of BSI and sepsis. The aim of this study was to identify patients at high risk for BSI who might benefit most from new, faster, etiological testing using neutrophil to lymphocyte count ratio (NLCR) and Shapiro score.METHODS: Adult patients (≥ 18 years) presenting at the emergency department (ED) with suspected BSI were prospectively included between 2014 and 2016 at Örebro University Hospital. Besides extra blood sampling, all study patients were treated according to ED routines. Electronic patient charts were retrospectively reviewed. A modified Shapiro score (MSS) and NLCR were extracted and compiled. Continuous score variables were analysed with area under receiver operator characteristics curves (AUC) to evaluate the ability of BSI prediction.RESULTS: The final cohort consisted of 484 patients where 84 (17%) had positive blood culture judged clinically significant. At optimal cut-offs, MSS (≥3 points) and NLCR (> 12) showed equal ability to predict BSI in the whole cohort (AUC 0.71/0.74; sensitivity 69%/67%; specificity 64%/68% respectively) and in a subgroup of 155 patients fulfilling Sepsis-3 criteria (AUC 0.71/0.66; sensitivity 81%/65%; specificity 46%/57% respectively). In BSI cases only predicted by NLCR> 12 the abundance of Gram-negative to Gram-positive pathogens (n = 13 to n = 4) differed significantly from those only predicted by MSS ≥3 p (n = 7 to n = 12 respectively) (p < 0.05).CONCLUSIONS: MSS and NLCR predicted BSI in the RISE cohort with similar cut-offs as shown in previous studies. Combining the MSS and NLCR did not increase the predictive performance. Differences in BSI prediction between MSS and NLCR regarding etiology need further evaluation.

- Hypothesis:Furosemide alters the permeability of the intrastrial fluid-blood barrier.Background:The cochlear sensory cells are protected by the blood-perilymph and intrastrial fluid-blood barriers, which hinder substances, including gadolinium-based contrast agents (GdCAs), to enter the endolymphatic space. High-dose furosemide causes transient shift of hearing thresholds and morphological changes in stria vascularis. Furosemide is also known to enhance drug-induced ototoxicity.Methods:Furosemide (400mg/kg b.w.) was injected i.v. in Balb/C mice (n=20). Twenty minutes later, the GdCA gadobutrol, gadopentetic acid, or gadoteric acid was injected i.v. The distribution of GdCA to the perilymphatic and endolymphatic spaces was studied with MRI (9.4T) for 250minutes.Results:The perilymphatic and endolymphatic spaces were signal-enhanced in all animals. Gadopentetic acid and gadoteric acid yielded similar signal enhancement in all three scalae, while gadobutrol yielded significantly higher enhancement in scala tympani than scala media (p=0.043) and scala vestibuli (p=0.043). The signal enhancement reached a plateau but did not decrease during the time of observation.Conclusion:Treatment with a high dose of furosemide before injection of a GdCA resulted in enhancement of the MRI signal in the endolymphatic space as well as the perilymphatic space, which supports our hypothesis that furosemide alters the permeability of the intrastrial fluid-blood barrier.
