Performing Instagram photography and the disciplining gaze

This paper approach participation in visual promotional strategies as a novel form of public performance. The paper examines the social rules and conventions of photography practices on visual social media platforms in a qualitative study of how 30 participants in so-called Instagram takeovers make sense of and perform photography as an embodied visual practice situated in time and space.A dramatu

Longitudinal enumeration and cluster evaluation of circulating tumor cells improve prognostication for patients with newly diagnosed metastatic breast cancer in a prospective observational trial

Background: Circulating tumor cells (CTCs) carry independent prognostic information in patients with metastatic breast cancer (MBC) on different lines of therapy. Moreover, CTC clusters are suggested to add prognostic information to CTC enumeration alone but their significance is unknown in patients with newly diagnosed MBC. We aimed to evaluate whether longitudinal enumeration of circulating tumo

Metabolism of chylomicron phosphatidylethanolamine in the rat

10 min after intravenous injection of 32P-labelled chylomicrons 69% of the [32P]phosphatidylethanolamine, but only 34% of the [32P]phosphatidylcholine, was cleared from plasma. Over this time period the plasma phosphatidylethanolamine concentration that was increased after the chylomicron injection returned to normal, indicating that the rapid clearance of [32P]phosphatidylethanolamine was primari

Hydrolysis of chylomicron retinyl ester by an acid retinyl esterase of rat liver

Rat liver homogenate hydrolyzed chylomicron remnant retinyl esters with pH optima 4.5, 6 and 8. The retinyl ester hydrolysis at pH 4.5 was correlated to the acid phosphatase activity in different subcellular fractions, and thus the highest activity was found in highly purified lysosomes. These fractions could also catalyze the reverse reaction, i.e., the esterification of retinol when incubated wi

Inhibibition of hepatic chylomicron remnant uptake in the cholestatic rat

[3H]retinal- or [3h]cholesterol- and [14C]fatty acid-labeled chylomicrons and chylomicron remnants were injected intravenously into normal rats and rats subjected to partial or total obstruction of the bile duct 8 or 48 h earlier. The clearance from plasma of the [3H]retinyl and the [3H]cholesteryl esters in 30-120 min was markedly decreased in rats with total obstruction, and the uptake of 3H by

Möten och icke-möten med blivande ämneslärare

Undervisning handlar i grunden om människor som möts. I de flesta undervisningssituationer etableras och knyts sociala band mellan lärare och elever och de inblandade aktörerna samverkar för att hitta en gemensam definition av undervisningssituationen. Men det finns också situationer där mötet tillintetgörs genom att den ena sidan (läraren eller eleven/eleverna) agerar asocialt responslöst, till f

The vision of children in Swedish compulsory school curricula, 1969-2011

Views of children and childhood are often closely related to discourses on how children should be treated. This relation between images of the child and discourses on treatment is more or less obvious in for example law, parenthood and education. In this paper I will present the figures of thoughts of children in the Swedish curriculums for the compulsory school, between the years of 1969 and 2011

Det började med en dinousarie

Att undervisa barn med autismspektrumdiagnos kan vara en särskild utmaning. En av USA:s experter på området är Brenda Smith Myles, som presenteras i denna artikel. Hon är ass. professor vid institutionen för specialpedagogik vid universitetet i Kansas.

En ödesdiger brygd

Hur har New Public Management i kombination med reformer som det fria skolvalet och friskolor påverkat verksamheten i svensk skola?

Gamma-Ray Emitting Radionuclides in People Living in Northern Sub Arctic Regions

År 1960 upptäcktes Cesium-137-aktivitet från atmosfäriska kärnvapenprovvid mätningar på lågaktivitets laboratoriet iLund. Denna händelse initierade mätningar av den svenska samiska befolkningen och iprodukter från ren som betar i de svenska fjällen. En semi-bärbarhelkropps detektor konstruerades med en detektionsgräns för 137Cs som var tillräckligt bra för att mäta människor med högakroppskoncentrIn 1960 Caesium-137 activity from atmospheric nuclear weapons test was dis-covered in measurements at the whole body gamma-ray counting laboratory inLund. This event initiated measurements of the Swedish Sami population, and inproducts from reindeer that bite lichens in the Swedish mountains. A semi-portable whole-body counter designed with a detection limit for 137 Cs at high radiation background

En bättre skola fås med medvetet och långsiktigt utvecklingsarbete

De viktigaste orsakerna till de växande resultatskillnaderna mellan skolor och mellan elever handlar om boendesegregation och det fria skolvalet.Ökade resurser kan vara en förutsättning men inte ett tillräckligt villkor för förbättring. I den här artikeln diskuteras hur fördelningen av resurser mellan grundskolor görs och vilka erfarenheter som finns av resursfördelning i jämlikhetsskapande syfte.

Barn gör rätt om de kan

Ingrid Bosseldal presenterar i den här artikeln den amerikanska psykologen Ross Greene, och reflekterar samtidigt över innebörden av de pedagogiska skillnaderna mellan att tänka "Barn gör rätt om de kan" och "Barn gör rätt om de vill" - och följderna av att välja det ena eller det andra.

Barn mer än objekt

Den svenska psykiatern David Eberhard hävdar att barn behöver fasta gränser, konsekvenspedagogik och att samarbetet med barnen gått för långt. I den här artikeln diskuteras dessa påståenden och prövas mot alternativa idéer om föräldra-barn-relationer.

"Babblarna" täljer guld av något som borde vara allmängods

Språkvetaren och specialpedagogen Irene Johansson utvecklade på 1970-talet en modell och ett material för språk- och talutveckling, den så kallade "Karlstadsmodellen", som därefter kommersialiserats genom produktionen av filmer, böcker, leksaker och andra artefakter, med den samlade rubriken "Babblarna". I den här artikeln presenteras några av Karlstadsmodellens grundförutsättningar: att den bygge

Magnesium status in Crohns disease as evaluated by intracellular analysis and intravenous magnesium infusion

The magnesium status was evaluated in 30 subjects with Crohn's disease and in 30 controls. Subjects with Crohn's disease had lower concentrations of magnesium in muscle biopsy specimens (p less than 0.001), mononuclear cells (p less than 0.05), and in urine collected during 24 h (p less than 0.001) as compared with controls. After intravenous infusion of 60 mmol magnesium and 80 mmol potassium to

Evaluation of zinc status in subjects with Crohn's disease

Zinc status was evaluated in 30 subjects with Crohn's disease. Intestinal resection had previously been performed in 23 of the subjects. The concentrations of zinc were determined in plasma, erythrocytes, percutaneous muscle biopsies, and in urine collected during 24 hours. The results were compared with those in 19 healthy controls. Most of the patients had a normal zinc status. The levels of zinZinc status was evaluated in 30 subjects with Crohn's disease.
