- The investigation of drug metabolism requires substantial amount of metabolites. Isolation from urine is tedious, therefore, the material obtained by synthesis is preferred. Substantial amounts of three tentative drug metabolites, phenolic glucuronides, have been prepared using easily available glycosyl donors. The final products [3(2-N-methyl-N-isopropylaminoethoxy)phenyl] beta-D-glucopyranosiduronic acid, 4-amino-3,5-dimethylphenyl beta-D-glucopyranosiduronic acid and [2(S)-propanoyl-6-O-naphthyl] beta-D-glucopyranuronic acid are useful as, for example, reference material in metabolite investigations.

- Inom idrottslärarutbildning har detutbildningsinnehåll som handlar om att utveckla studenters ämneskunskaper iidrott kraftigt reducerats under de senaste decennierna. Inte minst har den delav ämneskunskapen som handlar om studenters förmåga att delta i och undervisaom idrottsliga praktiker drabbats (Kirk 2010). När utrymmet för ett ämnesområdebegränsas aktualiseras frågor om innehåll och bedömning. Alltmedan de flestainom fältet är eniga om betydelsen för studenter att få erfarenheter av rörelseoch idrott under sin utbildning finns olika uppfattningar om huruvida man skabedöma studenters förmåga att praktiskt utöva idrott. Hur man förhåller sigdenna fråga har i hög grad visat sig vara kulturellt betingat (Backman &Pearson submitted, Herold & Waring 2009, Siedentop 2009, Tinning 2010). Isvensk idrottslärarutbildning har just den idrottsliga bedömningens vara ellerinte vara visat på en komplexitet och ambivalens (Backman & Pearson 2016).I en tid av alltmer begränsade resurser har problematiken delvis handlat omhuruvida man ska bedöma (och därigenom värdera) studentens förmåga att delta iidrott som ett mål i sig eller om man ska bedöma studentens förmåga attundervisa i och om idrott (Backman & Larsson 2016, Maivorsdotter et al2014). I de studier som belyst den idrottsliga färdighetens position ochbetydelse inom idrottslärarutbildning har studenters röst varit sparsamtförekommande. I denna studie vill vi därför, genom en implementering av eninternationellt etablerad modell för studentmedbedömning i bollspel (GamesPerformance Assessment Instrument, GPAI) (Oslin et al 1998) i kurser förblivande idrottslärare, ge röst åt studenters syn på studentbedömning avförmågan att spela bollspel. I studien har 140 studenter (N=140) pålärarprogrammet vidGymnastik- och idrottshögskolan i Stockholm deltagit. Studien är genomförd inom ramen för en ordinarie bollspelskurs om 3 hp som motsvarar 18 lektionstillfällen med 90 minuters undervisning vid varje tillfälle. Till detta lades två extra lektioner om 90 min för att genomföra studien/datainsamlingen. Studenterna har under och efter kursen bidragit till datainsamlingen i kursen genom ifyllande av etablerade bedömningsformulär där de analyserat varandras spelförmåga. Vidare har studenterna svarat på en utvärdering av hur GPAI implementerats i kursen med hjälp av ett enkätverktyg. Syftet med kursen som studenterna deltagit i är att studenterna ska utveckla sin spelförmåga, leda målspel i skolan samt didaktiska aspekter på målspel i skolan. Studien har omfattat studentmedbedömning i spelen handboll, basket och fotboll som inte enbart ska ses som en utbildning i dessa spel utan som representation för bollspel i allmänhet. Deltagarna i studien representerar alla studenter som hösten 2016 läste den beskrivna kursen. Alla studenter fick information om att deltagandet var frivilligt och att de kunde avbryta när som helst utan att det skulle på verka deras betyg eller vara negativt för dem på något annat sätt. Alla studenter ville vara med i studien. I vår preliminära analys har vi funnit att studenternas observationer av varandra visade på stor variation avseende spelförmåga. I utvärderingen av GPAI-projektet har studenterna uttryckt att de visserligen förstod syftet med GPAI-projektet, och att de förstod hur de skulle bidra till datainsamlingen genom att analysera varandras spelförmåga, men att de var tveksamma till relevansen av GPAI i en bedömningskontext i skolan. Resultaten kommer att analyseras vidare och diskuteras i relation till Shulmans begrepp ämneskunskap (Content Knowledge) och ämnesdidaktisk kunskap (Pedagogical Content Knowledge) samt i relation till teorier om bedömning. I en diskussion där perspektiven ofta begränsas till forskarens och/eller idrottslärarutbildarens kan studenter bidra med viktig kunskap om vad de ser som relevant kunskap för sin kommande yrkesroll.

Tidskriftsartikel (refereegranskat)abstract
- As a part of the discussion about how movement knowledge is valued in physical education teacher education (PETE), issues of assessment have been brought to the fore. Studies have shown that how and when movement knowledge is assessed is strongly culturally dependent and based different epistemological orientations. The aim of this paper is to analyse and discuss how preservice teachers in Sweden perceive assessment in an invasion games course according to the games performance assessment instrument (GPAI). The empirical material presented in this study is based on a web-survey carried out at the end of the invasion games course where the participants were asked to write comments of how the experienced GPAI and its relevance in school physical education. The findings suggest that the preservice teacher experience prediction and measurement of appropriate and non-appropriate behaviours in GPAI as problematic from a didactic perspective. The ideas of "correctness" and "appropriateness", which are fundamental in GPAI, is discussed in the relation to the socially critical constructivist epistemology that underpins Swedish PETE.

- Introduction: It has been consistently demonstrated that low aerobic fitness is causally linked to increased cardio-metabolic risk. Aerobic fitness has also been causally related to cognitive function. From adolescence and onwards, the inter-individual stability ("tracking") in fitness is fairly high. An individual's fitness level in adolescence is therefore a central determinant for future health. However, childhood predictors of adolescent fitness levels are largely unknown. The present study aimed at identifying personal, school-specific and structural determinants in childhood (age 10 yrs) for adolescent aerobic fitness (at age 16 yrs).Methods: Body mass index-based overweight status (normal weight vs overweight/obese, according to Cole et al.) and gross motor skills (based on the Tidén-Nyberg test) were measured at baseline in 209 Swedish children (mean [SD] age 9.8 [0.60] yrs) from randomly selected schools on Sweden. Immigration status (self-report) and average household income in quartiles on community level (register obtained) were used as possible structural confounders. Data on educational status of the PE teacher and lesson structure (gender-separated vs mixed classes) was obtained from the PE teacher. At the reexamination (at age 15.8 [0.33] yrs), aerobic fitness was estimated using the Åstrand-Ryhming nomogram. Low aerobic fitness was defined as below the first quartile (29.7 mL x min-1 x kg-1). Risk for low aerobic fitness was assessed using logistic regressionResults: Risk for low aerobic fitness at follow-up was lower in children who were normal weight (OR: 0.23.95% CI: 0.10 to 0.49) and in children with trained PE-teachers (OR: 0.40, 95% CI: 0.17 to 0.93), but higher among children with poor gross motor skills (OR:1.84, 95% CI 1.08 to 3.13) at baseline. Gender, immigration history, neighborhood economical status and lesson structure were all non-significant predictors of low adolescent fitness.Discussion: The results stress the importance for early overweight prevention and treatment and for professional identification and treatment of children with impaired gross motor skills at young ages. In Sweden, a lagre proportion of PE-teachers in lower grades lack formal PE-teacher education, which according to the present study poses a threat to children's future health. Early screening and treatment of children with limited motor proficiencies seems may help children adapting a physically active lifestyle and avoiding low fitness levels in adolescence and young adulthood.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: An individual's perceived competence in physical activities (PCPA) has been proven a powerful predictor for future physical activity. However, the perception of one¥s competence may differ over time, especially during childhood and adolescence but also between types of physical activities or tasks. Further, the predictors for PCPA are largely unknown, but overweight status and gross motor skills have been proposed as candidates. We sought to identify predictors for general PCPA in Swedish adolescents, and PCPA in three highly prevalent forms of physical activities in Swedish physical education (PE), namely swimming, aerobics and soccer.Methods: Body mass index-based overweight status (normal weight vs overweight/obese, according to Cole et al.) and gross motor skills (based on the TidÈn-Nyberg test) were measured in 352 Swedish children (160 girls and 192 boys) at baseline (age 10). Immigration status (self-report) and average community household income level (quartiles, register obtained) at 10 yrs were used as possible socio-cultural confounders. Data on educational status of the PE teacher responsible for education at age 10 yrs was obtained by self-report from the teachers. Self reported data on general PCPA and PCPA in soccer, swimming and aerobics at 16 yrs was obtained at follow-up and predictors for PCPA was identified using logistic regression.Results: Being overweight or obese (OR: 2.27, 95% CI: 1.18–4.38) and attending PE classes with unqualified teachers (OR: 2.41, 95% CI: 1.36–4.27) at age 10 yrs were both risk factors for low general PCPA a age 16 yrs. Concerning the selected activities, being overweight or obese at age 10 yrs predicted low PCPA in swimming (OR: 2.67, 95% CI:1.31–5.46) but not in the other activities at age 16 yrs. Poor gross motor skills at age 10 yrs predicted low PCPA at 16 yrs only in soccer (OR:1.48, 95% CI: 1.02–2.13). Female gender (OR: 0.21, 95% CI: 0.13–0.38), and higher socioeconomic status (OR: 0.71 per quartile, 95% CI: 0.55–0.92)at age 10 yrs were both found to be associated to lower risk for low PCPA in aerobics.Discussion: Overweight status and educational status of the PE teacher both affect the risk of having low general PCPA. The effect of gender, overweight status, gross motor skill and socio-economy seem to differ between specific activities, indicating that PCPA may be task specific in adolescents. These results may serve as background when planning physical activity interventions. Further, they stress the need for professional PE teachers to teach in younger classes.

Assessing Embodied Knowledge in Swedish PEH : the Influence of Physical Literacy
- 2013
-
Ingår i: ICSSPE Bulletin. - : International Council of Sport Science and Physical Education. - 1563-3632. ; :65
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- There is internationally a growing interest in the concept physical literacy and how it can be used in educational contexts. The aim of this contribution is to illustrate and describe how and in which way Swedish PEH has been influenced by physical literacy in the context of learning outcomes and assessment. The empirical material consists of the PEH curricula and the official supplementary material for qualitative assessment. Tensions between curricula, pedagogy, and assessment are discussed as physical literacy is linked to an individual’s potential and being in the world and not related to assessment of what separates people.
