Purpose: The purpose of this thesis is to tackle the paradox of governing free labour by exploring and drawing further understanding to the co-creation process in online brand communities. Originality: This study is the first to investigate co-creation from the theoretical perspective of the production of space and the first to introduce the concept of co-control in regards to the management of co

The Janzen–Connell hypothesis states that seedling survival increases with distance from the parent tree, which promotes regular spacing of species within a forest and thus biodiversity. Very few studies have tested this hypothesis in tropical Africa. This paper evaluates the occurrence of Janzen-Connell effects for seedlings and adult trees of the species Cola cordifolia in a dry tropical forest

On April 16th, 2026, the new legislative Government bill 2025/25:246 regarding stricter rules for young offenders was presented. The bill proposes a partial lowering of the age of criminal responsibility to 13 for severe crimes, and the introduction of youth imprisonment for the 13–14 age group. The purpose of this thesis is to examine the arguments behind the proposal and compare them with prev

This thesis aimed to explore the binding pocket of galectin-8N and galectin-3C. Both structure-based drug design and fragment-based drug discovery were utilized in this project, exemplifying the benefits of the different approaches. Structural determination of the proteins in complex with both high affinity ligands, and small fragments was achieved through x-ray crystallography. The structures of

The Swedish transport administration (Trafikverket) uses turnkey contracts as a tool in their work with the assignment from the Swedish government to increase innovation and productivity in the construction sector which railway is included in. Qualitative interviews of the three different actors: clients (Trafikverket), constructors and consults have been made for the study. This is to get a pictu

BackgroundChildhood constipation is increasingly common, yet its prevalence is uncertain. This study examines comprehensive national data for trends in medically treated childhood constipation over a period of 18 years.MethodsIncluded were all Swedish children, 0–14 years, 2006–2023, and all prescriptions for constipation, using the national Swedish Prescribed Drug register. The primary outcome wa

Popular Abstract in Swedish Det mesta av det genetiska materialet i en eukaryot cell finns samlat till kärnan och är organiserat i kromosomer. Varje gång en cell delas kopieras kromosomerna så att de båda resulterande cellerna får ett bibehållet kromosomantal. Den mekanism som styr denna replikeringsprocess förmår dock inte kopiera de yttersta kromosomändarna, vilket resulterar i att dessa blir koTelomeres are specialized complexes of DNA and proteins that cap and confer stability to the ends of eukaryotic chromosomes. The telomeric DNA of most eukaryotes is composed of tandemly arranged short repeats. Within the budding yeasts these repeats are diverged in length as well as in nucleotide composition. However, they contain a sequence resembling the consensus binding sequence of the major t

Popular Abstract in Swedish En av de viktigaste frågeställningarna inom molekylär genetik är hur uttrycket av människans ca 30-40 000 gener regleras i tid och rum. En typ av reglering som är väldigt viktig är transkriptionell reglering och denna utövas av proteiner som kallas transkriptionsfaktorer. Dessa binder till specifika områden i DNA strängarna i närheten av genkodande regioner och kan däriNeuroblastoma is a childhood tumor derived from primordial neural crest cells. The tumor cells exhibit a phenotype similar to that of developing neuroblasts, which indicates that the tumor arises due to perturbed differentiation of the sympathetic nervous system. It is well established that transcription factors control the steps leading to neuronal differentiation, and a number of basic helix-loo

Smaller size and lower weight are always the targets of the power electronic product development. This work introduces two new topologies of auxiliary converters which have the feature of fewer components and fewer number of energy conversion stages comparing with the conventional auxiliary converter used in railway applications. The initial proposal of the proposed new topology is based on the id

A key question for evidence-based medicine (EBM) is how best to model the way in which EBM should “[integrate] individual clinical expertise and the best external evidence” (Sackett et al. 1996). We argue that the formulations and models available in the literature today are modest variations on a common theme and face very similar problems. For example, both the early and updated models of eviden

The purchasing strategies in the construction industry have been considered by many writers in construction management as short-term and arms-length. However, a different picture is portrayed in the manufacturing industry, where the purchasing strategies are mostly long-term to secure supply for production. Industrialized building is at the crossroad between construction and manufacturing, which r

Tid och envishet är viktiga faktorer för att lyckas med innovation. Om detta och andra faktorer står att läsa i denna bok. Boken är född ur ett inspirerande, lärorikt år inom ramen för forskningsprogrammet PIEp: Product Innovation Engineering program. Ett år då vi forskare mött nya människor, nya företag, fått nya insikter, men också en bekräftelse på att svenskt näringsliv tycks göra allt för att

Popular Abstract in Swedish Inom jonstråleanalysen används en partikelstråle, vanligtvis av protoner eller alfapartiklar, med hög energi för undersökning av prov. Då dessa partiklar skjuts in i provet sker kollisioner, reaktioner eller annan form av växelverkan med elektroner och kärnor i provets inre. En del av dessa processer ger upphov till högenergetisk strålning som kan studeras med lämpliga In nuclear microprobe experiments, high resolution maps of the measured parameter, e.g. element- or mass distribution, in a sample can be produced with a variety of ion beam analytical techniques. The principle underlying all the techniques is that ions at MeV energies are used as projectiles to cause interactions with the target material. Because of the limited range of ions in matter, there is a

The group of cetrarioid lichens with globose ascospores includes 37 species from eight genera. Phylogenetic analysis, using program PAUP 3.1.1, was carried out on two different data sets – morphological (incl. anatomical and chemical) and molecular characters (ITS1, 5.8S, and ITS2 rDNA sequences) – to verify the correspondence of current taxonomy to the probable evolution of the taxa involved.
