Popular AbstractSociologen Niklas Luhmann är en av få samhällsvetare som kommit att utveckla en egen teori. Det har skett genom en vidareutveckling av systemteorin och med otaliga inspirationer från klassisk och modern sociologi, filosofi, rättsteori, kommunikationsteori, kognitionsforskning osv. Luhmanns vittomfattande skriftliga verk gör honom till en av de mest betydande sociologerna överhuvudtThis thesis is divided into two main parts. The first is an exposé of Niklas Luhmann's comprehensive sociological systems theory, including the basic tenets of the theory, its historical development and central concepts, and discussions. Systems theory is a theory about the distinction between system and environment. Within the framework of Luhmann's systems theory, one can discern three primary l

The development of soft anisotropic building blocks is of great interest for various applications in soft matter. Furthermore, such systems would be important model systems for ordering phenomena in fundamental soft matter science. In this work, we address the challenge of creating hollow and anisotropically shaped thermoresponsive microgels, polymeric networks with a solvent filled cavity in thei

The work in this thesis was carried out to highlight important chemical pathways in skeletal mechanisms for the three smallest alcohol fuels (methanol, ethanol and npropanol), two representative fuel alkanes n-heptane and n-decane, and finally the biodiesel surrogates, methyl-decanoate, methyl-5-decenoate, and methyl-9-decenoate. This aim was set up to further the efforts of creating Computational

The band offsets occurring at the abrupt heterointerfaces of suitable material combinations offer a powerful design tool for high performance or even new kinds of devices. Because of a large variety of applications for metal-semiconductor heterostructures and the promise of low-dimensional systems to present exceptional device characteristics, nanowire heterostructures gained particular interest o

The Hyogo and Sendai frameworks stress that risk assessments should inform plans. However, it is unclear how, in theory, risk assessments and plans are conceptually related and how, in practice, they inform each other. This study aims to fill this knowledge gap. Conceptually, it proposes an explicit link between risk assessments and plans via the capability of the responding organisation and its e

We study the permeability and selectivity ('permselectivity') of model membranes made of polydisperse polymer networks for molecular penetrant transport, using coarse-grained, implicit-solvent computer simulations. In our work, permeability P is determined on the linear-response level using the solution-diffusion model, P = KDin, i.e., by calculating the equilibrium penetrant partition ratio K and

Sustainable tourism (ST) has recently become the mainstream of the tourism industry and, accordingly, has influenced contemporary tourism research. However, ST is not just theories about indications and contraindications of global travel, but also a specific language that needs mastering to take sustainability work forward. In other words, what research receives recognition depends on the proficie

Sustainable business model innovation is increasingly viewed as a lever for systems change for sustainability across businesses and industries. Banks hold a unique intermediary role in sustainable development, but also have a difficult position after the 2008 financial crisis. This paper aims to explore business models for sustainability in the service industry, particularly banking. It explores t

Technology is a compulsory subject at Swedish elementary schools and, according to the syllabus, helps students develop their ability to examine different technological solutions and reason how these solutions affect society, environment, and humans. An important challenge for educational research is to analyse and understand the consequences and impacts of technologies on students’ learning, well

Background: There is limited knowledge about the perspective of patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT) about having a sibling as donor. It is essential to understand the main concerns of stem cell recipients in order to enable nurses to provide person-centred care. Objectives: The study aim was to explore patients’ main concerns about having a sibling stem c

Early life environments shape phenotypic development in important ways that can lead to long-lasting effects on phenotype and fitness. In reptiles, one aspect of the early environment that impacts development is temperature (termed 'thermal developmental plasticity'). Indeed, the thermal environment during incubation is known to influence morphological, physiological, and behavioral traits, some o

It is widely known that there is a discrepancy between educational policy on the one side, and teaching and learning practices on the other. Most studies have been focusing on the sociocultural and micropolitical frames that shape teachers’ understandings and enactments of teaching, and that cause the vast diversity of classroom practices around the world. This article wants to draw attention to t

Understanding the mechanical behaviour of porous rocks and how this influences the fluid flow is key in a number of resource engineering challenges, in particular hydrocarbon production and CO2 sequestration. Deformation in these porous materials is, in general, not homogeneous, as deformation localises into narrow shear or compaction bands, which might then evolve into fractures. These local defo

Ex vivo manufactured red blood cells (RBC) generated from immortalized erythroid cell lines which can continuously grow are expected to become a significant alternative in future transfusion therapies. The ectopic expression of human papilloma virus (HPV) E6/E7 gene has successfully been employed to establish these cell lines. To induce differentiation and maturation of the immortalized cell lines

Involving professionals in research can ensure the acquisition of knowledge, that is relevant, applicable and sustainable. Professionals are people who work in health systems, or organisations that contribute to health systems, such as practitioners, managers or other decision-makers. They have context-specific knowledge which the researchers often lack. Therefore, when they are involved in resear
