The Paradoxes of Good Intentions : The theory and practice of reforms reflected in teachers´ experiences

Popular AbstractAvhandlingens titel Den goda viljans paradoxer skall förstås på följande sätt. I utredningar och propositioner hävdar utredare, skolpolitiker och administratörer att lärarna skall bemyndigas, det vill säga de skall tillskrivas ett mandat i skolan. Detta mandat skall ge lärarna ett visst självständigt beslutsfattande i en ny mötesform som kallas arbetsenheter. Denna mötesform stipulThe theory and practice of reform as reflected in teachers’ experience of meetings in schools. This empirical study has been carried out in a coeducational school for pupils up to the age of 16 ("grundskola") during the school years 1988-89 up to and including 1991/92. In this study 26 teachers and five school administrators - head teachers and deputy-head teachers - have been interviewed. Person

Molecular self-diffusion in micellar and discrete cubic phases of an ionic surfactant with mixed monovalent/polymeric counterions

The molecular self-diffusion in concentrated aqueous mixtures based on an oppositely charged po ymer-surfactant pair has been investigated by NMR pulsed field gradient techniques. The investigated structures were an ordered cubic Pm3n phase (ca. 50 wt % water) and a disordered micellar phase, both containing cetyltrimethylammonium (CTA(+)) micelles with mixed acetate (Ac-) and polyacrylate (PA(-))

Violaxanthin accessibility and temperature dependency for de-epoxidation in spinach thylakoid membranes

Using DTT and iodoacetamide as a novel irreversible method to inhibit endogenous violaxanthin de-epoxidase, we found that violaxanthin could be converted into zeaxanthin from both sides of the thylakoid membrane provided that purified violaxanthin de-epoxidase was added. The maximum conversion was the same from both sides of the membrane. Temperature was found to have a strong influence both on th

Ultrasound enhanced thrombolysis in experimental retinal vein occlusion in the rabbit

AIMS: To investigate if it was possible to lower the dose of streptokinase and maintain an effective thrombolysis by adding pulsed low energy ultrasound. METHODS: 53 retinal veins in 27 rabbits were occluded by rose bengal enhanced laser treatment. Six rabbits were treated with streptokinase (50,000 IU/kg), 10 rabbits were treated with a low dose of streptokinase (25,000 IU/kg), and 11 rabbits wer

Simulation of the neural response to the odour stimulus

The paper is aimed at the description of the newly introduced model used to simulate the neural response to the chemical stimulus. A potential difference across the living cell or tissue depends usually on the chemical excitation of this living entity. The peculiar case of chemical excitation is the odour recognition across animal kingdom, in particular by various insects. A potential difference i

A general method for bead-enhanced quantitation by flow cytometry

Flow cytometry provides accurate relative cellular quantitation (percent abundance) of cells from diverse samples, but technical limitations of most flow cytometers preclude accurate absolute quantitation. Several quantitation standards are now commercially available which, when added to samples, permit absolute quantitation of CD4+ T cells. However, these reagents are limited by their cost, techn

LIVING WITH CHILDHOOD DIABETES - Family Experiences and Long-term effects

The overall aim of this thesis was to investigate families’ experiences when a child is diagnosed as having type 1 diabetes, and at one and three years after diagnosis. Since childhood health and the circumstances around it in the family have been shown to have a lasting impact on adult health and circumstances, an additional aim was to examine the long-term effect of childhood diabetes on educati

Epidemiology of diabetes in a well defined population in Sweden: the Skaraborg Diabetes Registry

Popular Abstract in Swedish Tidstrender i prevalens, incidens och mortalitet följdes för 15000 diabetespatienter under 1991-2005. Kliniska fynd, C-peptidanalyser och öcellsantikroppar jämfördes med avseende på förmågan att särskilja typ 1 från typ 2 diabetes och faktorer som påverkade prognosen undersöktes. Incidens och ålder vid insjuknandet förhöll sig oförändrade över tid, men prevalensen ökadTime trends in prevalence, incidence and mortality was followed in 15000 diabetic patients in 1991?2005. Clinical findings, C-peptide protocols, and islet antibodies were compared in their ability to distinguish type 1 from type 2 diabetes, and factors associated with the prognosis of diabetes were explored. The incidence and the age at onset remained stable but the prevalence of diabetes increas

The components of excess mortality after hip fracture

A high excess mortality is well described after hip fracture. Deaths are in part related to comorbidity and in part due directly or indirectly to the hip fracture event itself (causally related deaths). The aim of this study was to examine the quantum and pattern of mortality following hip fracture. We studied 160,000 hip fractures in men and women aged 50 years or more, in 28.8 million person-yea

Pair correlation in deformed neutron-drip-line nuclei: The eigenphase formalism and asymptotic behavior

The Hartree-Fock-Bogoliubov (HFB) equation for deformed nuclei in a simplified model is solved in coordinate space with correct asymptotic boundary conditions, in order to study the pair correlation in nuclei close to the neutron drip line. The eigenphase formalism is applied, when the upper components of HFB radial wave functions are continuum wave functions. Calculated occupation probabilities o

Abundances of vanadium and bromine in 3 Centauri A - Additional odd-Z anomalies

We report abundance excesses of 1.2 and 2.6 dex, respectively, for vanadium and bromine in the hot, peculiar star 3 Cen A. Abundances for these two odd-Z elements have not been previously reported for this star. Taken with previous work, they strengthen the case of the origin of the abundance peculiarities by diffusion.

Food and secretagogue stimulation decrease the digestive enzyme content remaining in the rat pancreas

The aim of the study reported here was to investigate changes in the digestive enzyme content in the pancreas after food and secretagogue stimulation. Rats from which food had been withheld overnight were either fed (between 6 and 8 a.m.) or not before euthanasia and pancreatic excision (at 8 a.m.: 21 not fed and 21 fed) and at 4 (12 p.m.: six not fed and six fed) and 8 h later (4 p.m.: six not fe

The genus Pilosella in the Nordic countries

An unprejudiced revision of the genus Pilosella (Asteraceae) in the Nordic countries has been attempted. A completely new system for the taxonomy of these mostly facultative apomicts is presented. It is argued that all existing systems are inappropriate in the light of the complicated, and largely unknown, reproductive biology of these taxa. Previous systems have either treated these taxa as oblig

Macrophages in inflammatory bowel disease

Blood monocytes which differentiate into tissue macrophages, are unique in that they can not only initiate immune responses but can also be effector cells which contribute to the resolution of these responses. There is no single activation phenotype, and macrophages can be induced to differentiate into cells that either exacerbate or inhibit acute inflammation. Similarly, these cells can promote,
