Tidigare forskning om motivation vid lärande har tenderat att fokusera på attributioner (de tolkningar elever och andra gör av orsaker till framgångar och misslyckanden) självuppfattning, målorientering och elevers autonomi. Denna avhandling syftar dels till att beskriva bakgrunden och skolgången för de elever som går på gymnasiets estetiska programs musikgren, dels till att mäta den motivation deIn previous studies research on motivation in education has tended to be focused on attribution (perceived causes of success and failure), self perception, goal orientation and autonomy. This thesis aims to describe the background and schooling of music students and to measure their motivation for music education. Motivation is viewed as a cognitive process, which influences learning through achie

Phosphodiesterase type 3B (PDE3B) has been shown to be activated and phosphorylated in response to insulin and hormones that increase cAMP. In order to study serine/threonine protein phosphatases involved in the regulation of rat adipocyte PDE3B, we investigated the phosphorylation and activation of PDE3B in vivo in response to phosphatase inhibitors and the dephosphorylation and deactivation of P

The human platelet cilostamide- and cGMP-inhibited cAMP phosphodiesterase (cGI-PDE) was rapidly purified approximately 19,000-fold to apparent homogeneity using single step affinity chromatography on the isothiocyanate derivative of cilostamide coupled to aminoethyl agarose. Within 24 h, 30 micrograms of enzyme protein was obtained from 20 ml of packed platelets. Vmax for cAMP and cGMP was 6.1 and

Popular Abstract in Swedish Med utgångspunkt i elevers väljande till gymnasieskolan har denna studie fokuserat på hur eleverna upplever detta val och med särskild betoning på samtalen mellan skolans syokon-sulenter (studie- och yrkesvägledare) och elever. Åtta elever har valts ut och samtliga deras samtal i årskurs nio med vägledare (4 stycken) har videoinspelats och analyserats. Dessutom har elevThe main purpose of this study is to highlight the counselling interview in connection with the choice of upper secondary school from three perspectives, the student's, the counsellor's and society's. The intention is to describe and analyse the counselling interview in the ninth grade with relation to: · the student's expectations, perceptions and values before and after the interviews, · the co

OBJECTIVE—To estimate the prevalence and severity of diabetic retinopathy (DR) 10 years after diagnosis in a nationwide population-based cohort study of young adult diabetic patients in Sweden. RESEARCH DESIGN AND METHODS—The Diabetes Incidence Study in Sweden (DISS) aims to register all incident cases of diabetes aged 15–34 years in Sweden. In 1987–1988, 806 cases were reported, and 627 (78%) of

OBJECTIVE--To investigate whether a lack of glutathione-S-transferase mu (GSTM1) activity was related to an increased risk for adverse outcome after asbestos exposure. METHODS--A study was made of 78 male former asbestos cement workers, with retrospective cohort data on exposure, radiographical findings, and lung function. Venous blood samples were obtained for the analysis of GSTM1 polymorphism b

Background and Objectives. Although anagrelide is widely used in the treatment of throm-bocythemia in myeloproliferative diseases, there is currently limited information on the efficacy and toxicity of its long-term use. This prospective study investigated clinical toxicity and efficacy of anagrelide during two years of treatment. Design and Methods. A multicenter, open, phase II study of anagreli

Aqueous di persions of a porcine lung surfactant (PLS) extract with and without cholesterol supplementation were analyzed by X-ray scattering. Lamellar liquid-crystalline and gel-type bilayer phases are formed, as in pure phosphatidylcholine (PC)-cholesterol systems. This PLS extract, developed for clinical applications, has a cholesterol content of less than 1% (w/w). Above the limit of swelling,

BACKGROUND: Overdose (OD) is a common cause of death in opioid users. Also, many current opioid users report a history of non-fatal OD. The present study aimed to identify factors associated with a history of non-fatal OD. METHODS: A sample of 7085 Swedish criminal justice clients with alcohol or drug misuse was assessed, using the Addiction Severity Index. Subjects reporting use of opioids during

OBJECTIVES: The methyltransferase genotype and pregnancy both influence the arsenic metabolism phenotype, but it is unknown whether these factors interact, explaining the drastic changes in the efficiency of arsenic metabolism observed among pregnant women. The aim of this study was to evaluate the relative contribution of the methyltransferase genotype and pregnancy to the arsenic metabolism phe

BACKGROUND: Type 2 diabetes mellitus is thought to develop from an interaction between environmental and genetic factors. We examined whether clinical or genetic factors or both could predict progression to diabetes in two prospective cohorts. METHODS: We genotyped 16 single-nucleotide polymorphisms (SNPs) and examined clinical factors in 16,061 Swedish and 2770 Finnish subjects. Type 2 diabetes d

The validity of atrial fibrillation (AF) diagnoses in national registers for use as endpoints in prospective studies has not been evaluated. We studied the validity of AF diagnoses in Swedish national hospital discharge and cause of death registers and the occurrence of and risk factors for AF in a middle-aged Swedish population using these registers. Our study included the 30,447 individuals (age

AIMS/HYPOTHESIS: To study the heritability and familiality of type 2 diabetes and related quantitative traits in families from the Botnia Study in Finland. METHODS: Heritability estimates for type 2 diabetes adjusted for sex, age and BMI are provided for different age groups of type 2 diabetes and for 34 clinical and metabolic traits in 5,810 individuals from 942 families using a variance compone

Purpose We investigated whether active video gaming (AVG) could bring about regular, enjoyable, physical exercise in children treated for brain tumours, what level of physical activity could be reached and if the children's physical functioning improved. Methods Thirteen children, aged 7-17 years, were randomised to either AVG or waiting-list. After 10-12 weeks they crossed-over. Weekly Internet c

BACKGROUND AND OBJECTIVES: During the past 10 years several DNA-typing methods have been developed to complement routine serological typing for determination of polymorphisms in the ABO, RH, KEL, JK and FY blood group genes. However, the molecular basis of blood groups can differ widely between ethnic groups. The purpose of this study was to evaluate selected DNA-based methods for phenotype predic

STUDY OBJECTIVE. To evaluate the effect of family therapy on childhood obesity. DESIGN. Clinical trial. One year follow-up. SETTING. Referral from school after screening. PARTICIPANTS. Of 1774 children (aged 10 to 11), screened for obesity, 44 obese children were divided into two treatment groups. In an untreated control group of 50 obese children, screened in the same manner, body mass index (BMI

We investigated several aspects of the role of physical activity in colon and rectal cancer etiology that remain unclear in the European Prospective Investigation into Nutrition and Cancer. This cohort of 413,044 men and women had 1,094 cases of colon and 599 cases of rectal cancer diagnosed during an average of 6.4 years of follow-up. We analyzed baseline data on occupational, household, and recr

Energy turnover in the isolated rat portal vein was investigated by measurement of oxygen consumption (JO2) and lactate production (JLA) under simultaneous recording of mechanical activity. In spontaneous activity under aerobic conditions and at optimal muscle length JO2 and JLA were 0.55 and 0.62 micromol/min X g, respectively, corresponding to an ATP-production of 4.3 micromol/min X G. When musc

Background: Albumin may be beneficial in patients with septic shock but availability is limited and cost is high. The objective of the present study was to investigate if the use of dextran-70 in addition to albumin and crystalloids influences organ failure or mortality in patients with severe sepsis or septic shock. Methods: Patients with severe sepsis or septic shock (n = 778) admitted to a univ
