This paper evaluates the Swedish school reform that was implemented in 1992, at upper secondary school level. The reform implies that independent schools are welcome to compete on the school market and are publicly funded. This reform has led to an increase in the share of students attending independent schools. Several estimations are performed in this paper on what impact this increase of compet
My primary objective in this study was to investigate the impact of the upbringing environment on the development of children’s effortful control and achievement motivation. Twenty-five SOS Children’s Village- and 33 family-raised children reported on achievement motivation, whereas SOS Village and family mothers assessed children’s effortful control along with emotion regulation as an additional
Popular Abstract in Swedish Membranproteiner är tämligen svåra att digerera med enzym som trypsin. Mindre specifika enzym såsom elastase och pepsin har dock visat sig mer effektiva. Databassökningar med dessa icke-tryptiska peptider är mindre verkningsfulla pga avsaknaden av laddning vid peptidens N-terminal och C-terminal samt brist på sekvensspecificitet. Vi beskriver en metod med specifik N-teMembrane proteins are fairly refractory to digestion especially by trypsin. Less specific proteases like elastase and pepsin are much more effective. However database searching using non-tryptic peptides is much less effective due to the lack of charge localisation at the N- and C-termini and the absence of sequence specificity. We describe a method for N-terminal specific labelling of peptides fr
This thesis describes the affinity and enantiomeric selectivity of the cellobiohydrolase Cel7A (isolated from Hypocrea jercorina). The chiral recognition of the enzyme has been studied with respect to amino alcohols and new ligands have been designed, based on the structure of the common ?-blocker propranolol. Capillary electrophoresis have been used to determine the dissociation constants of the
This report covers the project period from 1.4.2003 to 31.08.2005. Project organisation, administration including the accounts, and the work carried out are reported. Besides, suggestions for copyright are put forward together with plans for dissemination activities and need for further research. The NAME was developed by the project group, consisting of all partners who have all contributed in an
The transport sector is facing serious challenges in meeting long-term sustainability criteria. Radical changes in the design of vehicles to attain competitive vehicles with substantially better environmental performance will probably constitute an important part in a future sustainable transport sector. The aim of the study described in this thesis is to assess the long-term options currently und
Popular Abstract in Swedish Som titeln antyder behandlar avhandlingen titrerande polyelektrolyter, d.v.s. stora molekyler med många syra-basgrupper. Sådana molekyler kan vi finna lite överallt, ja till och med i våra kroppar, som innehåller en mängd olika polyelektrolyter. Deras egenskaper kan variera starkt beroende på omständigheterna och har många biologiska och industriella tillämpningar. Att Different models and statistical mechanical approximations for titrating polyelectrolytes are studied and the results compared with Monte Carlo simulations and experimental data. Three types of models have been used in the simulations: i) rigid structures and freely jointed chains with ii) rigid bonds and iii) flexible, harmonic bonds. Sampling is facilitated for the latter two by the use of pivot
Popular Abstract in Swedish En central fråga av både teoretisk och praktisk betydelse är varför vissa företag är mer framgångsrika - vilket ofta uttrycks som att de har större konkurrensfördelar - än andra. Speciellt uppkommer frågan då vissa fabriker inom samma företag år efter år uppvisar ett bättre ekonomiskt resultat än andra. Fokus i denna avhandling är att förstå varför så sker inom ett utva
According to the traditional view, the relation between morphology and syntax is the following: while morphology builds up word forms—typically by combining roots with other roots and with affixes, but also by applying other operations to them, syntax takes fully inflected words as input and combines them into phrases and sentences. The division of labour between morphology and syntax is thus perf
The aim of this study was to determine whether muscle fibre degeneration brought about by chronic low-frequency electrical stimulation was related to the pattern and frequency of stimulation. Rabbit fast-twitch muscles, tibialis anterior and extensor digitorum longus, were stimulated for 9 days with pulse trains ranging in frequency from 1.25 Hz to 10 Hz. Histological data from these muscles were
Malaria parasites are a widespread and species-rich group infecting many wild populations of mammals, birds and reptiles. Studies on humans have demonstrated that genetic factors play a key role in the susceptibility and outcome of malaria infections. Until the present study, it has not been examined whether genetic variation in hosts is important for the outcome of malaria infections in natural a
