- Denna studie analyserar hur framställningen av det sexåriga barnet har förändrats genom historien, beroende på hur samhället har hanterat frågor om skolplikt, sexåringens skolmognad och skolstart. Policydokument från 1940-talet fram till 2017 har analyserats med hjälp av begreppen subjektifiering och kvalificering. Policydiskurser formulerar mening och sanningar om barnet men ger också en indikation på vad som är problemen och hur dessa problem ska lösas. Policydiskurser innehåller också ekonomiska argument och formulerar den roll som utbildning spelar i att förbereda barn och unga för framtida utbildning och arbetsliv. Vi svarar på frågorna: vem är sexåringen i policydokumenten och vad ska sexåringen kvalificeras för genom utbildning? Resultaten visar att det sker en förskjutning från beskrivningar av den omogna sexåringen till den presterande och skolpliktiga eleven. I början av tidsperioden formuleras diskurser om det omogna och problematiska barnet som inte förväntats klara av att passera nålsögat för att bli insläppt i skolan. Runt millennieskiftet sker dock ett diskursivt brott då barnets förutsättningar hamnar i förgrunden. Problemet kom då istället att handla om hur skolan ska anpassas till det kompetenta barnets individuella förutsättningar. Perioden är dock kort, och en bit in på 2010- talet är det återigen den skolpliktiga, presterande och mätbara eleven som förväntas anpassa sig till statens krav. Denna förskjutning kan sättas i en global kontext som framhäver konkurrens, kunskapseffektivitet och ekonomiska incitament för skolarisering

- The Hydraulic Institute has just completed the task of developing a new ANSI/HI standard on Rotodynamic (Centrifugal) Slurry Pumps covering nomenclature, definitions, applications, and operation. The standard provides examples of all the different types of pumps available and has an extensive section on definitions. Slurries and their effect on performance and wear are covered. A slurry service class is established which then is used to limit velocities and head produced per pump to give acceptable wear. A special section deals with mechanical seals and a new method for determining flange loads is presented and guidelines are given for commissioning, start-up etc.The head limits and the performance derating are of special interest when centrifugal slurry pumps are applied to thickened tailings and paste-like slurries. For Newtonian liquids, the Hydraulic Institute's Viscosity Correction Method (ANSI/HI 2004) provides a procedure widely used for viscous effects on the performance. For the homogeneous flow of viscous slurries, the new slurry standard refers to an applicable viscosity to use with the method and to "consult the pump manufacturer for guidance regarding non-Newtonian slurry pump performance."Experimental performance results are presented here and applied to the viscosity correction method for a simulated tailings product slurry characterized by a fully sheared yield stress of about 100 Pa, evaluated from pipeline data. The pump was a GIW-LCC type three-vane all metal unit with a 0.3m-diameter impeller having an open shroud with a simple auger-like inducer. Results are also given for an underground hydraulic fill product characterized by a Newtonian kinematic viscosity which is 1300 times that for water. The different results obtained here point out the strong influence the rheological behavior has on the choice of pump size and the power requirement.

- AIMS/HYPOTHESIS: We determined whether hepatic fat content and plasma adiponectin concentration regulate VLDL(1) production. METHODS: A multicompartment model was used to simultaneously determine the kinetic parameters of triglycerides (TGs) and apolipoprotein B (ApoB) in VLDL(1) and VLDL(2) after a bolus of [(2)H(3)]leucine and [(2)H(5)]glycerol in ten men with type 2 diabetes and in 18 non-diabetic men. Liver fat content was determined by proton spectroscopy and intra-abdominal fat content by MRI. RESULTS: Univariate regression analysis showed that liver fat content, intra-abdominal fat volume, plasma glucose, insulin and HOMA-IR (homeostasis model assessment of insulin resistance) correlated with VLDL(1) TG and ApoB production. However, only liver fat and plasma glucose were significant in multiple regression models, emphasising the critical role of substrate fluxes and lipid availability in the liver as the driving force for overproduction of VLDL(1) in subjects with type 2 diabetes. Despite negative correlations with fasting TG levels, liver fat content, and VLDL(1) TG and ApoB pool sizes, adiponectin was not linked to VLDL(1) TG or ApoB production and thus was not a predictor of VLDL(1) production. However, adiponectin correlated negatively with the removal rates of VLDL(1) TG and ApoB. CONCLUSIONS/INTERPRETATION: We propose that the metabolic effect of insulin resistance, partly mediated by depressed plasma adiponectin levels, increases fatty acid flux from adipose tissue to the liver and induces the accumulation of fat in the liver. Elevated plasma glucose can further increase hepatic fat content through multiple pathways, resulting in overproduction of VLDL(1) particles and leading to the characteristic dyslipidaemia associated with type 2 diabetes.

Forskningsöversikt (refereegranskat)abstract
- Insulin resistance is a key feature of the metabolic syndrome and often progresses to type 2 diabetes. Both insulin resistance and type 2 diabetes are characterized by dyslipidemia, which is an important and common risk factor for cardiovascular disease. Diabetic dyslipidemia is a cluster of potentially atherogenic lipid and lipoprotein abnormalities that are metabolically interrelated. Recent evidence suggests that a fundamental defect is an overproduction of large very low-density lipoprotein (VLDL) particles, which initiates a sequence of lipoprotein changes, resulting in higher levels of remnant particles, smaller LDL, and lower levels of high-density liporotein (HDL) cholesterol. These atherogenic lipid abnormalities precede the diagnosis of type 2 diabetes by several years, and it is thus important to elucidate the mechanisms involved in the overproduction of large VLDL particles. Here, we review the pathophysiology of VLDL biosynthesis and metabolism in the metabolic syndrome. We also review recent research investigating the relation between hepatic accumulation of lipids and insulin resistance, and sources of fatty acids for liver fat and VLDL biosynthesis. Finally, we briefly discuss current treatments for lipid management of dyslipidemia and potential future therapeutic targets.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Senaste halvåret har en arbetsgrupp på Svenska Psykiatriska Föreningens uppdrag arbetat med problem som finns runt psykiatriska diagnoser. En viktig del av arbetet har varit att ta fram ett diskussionsunderlag främst riktat till dem som i sitt arbete sätter psykiatriska diagnoser. Detta underlag syftar till att problematisera, inte till att polemisera. Självklart har vi i gruppen uppfattningar, men vi har inte alltid samma uppfattningar inom detta område. En sak är vi dock helt överens om – psykiatrisk diagnostik är svårt! samt att det idag finns uppenbara problem.

Does workplace experience enhance political participation? : A critical test of a venerable hypothesis

- Several schools of thought claim that citizens can develop their democratic skills at the workplace. Here I focus on the hypothesis put forward by Carole Pateman and by Sidney Verba and colleagues that state that by practicing civic skills and democratic decision-making at the workplace, citizens become more active in politics. I test the hypothesis with a nationally representative panel survey of the Swedish population. My findings contradict previous empirical research as no impact on political participation was discovered. I argue that the effects may have been overestimated in prior studies because the tests were based on cross-sectional data: insufficient care was taken with a number of significant methodological problems. The study points to the importance of using panel models when investigating the causes of political participation.
