This thesis investigates educational software: computer software applications which serve to support teachers and improve learning outcomes for students. It aims to delineate the field of educational technology research as an interdisciplinary field and exemplify some of the methods used for approaching the many research questions that arise from asking what makes good educational software. The ov
Aim: Studies examining the long-term effects of neonatal music interventions on the cognition of children born preterm are scarce. We investigated whether a parental singing intervention before term age improves cognitive and language skills in preterm-born children. Methods: In this longitudinal, two-country Singing Kangaroo, randomised controlled trial, 74 preterm infants were allocated to a sin
BACKGROUND: Public health policies and healthcare quality play a pivotal role on the health outcome level and disparities across sociodemographic groups. However, there is little evidence on their role on disparities in life expectancy (LE) and life disparity (LD) in low and middle income countries. The present study aimed to assess the contributions of avoidable mortality, as a measure of inter-s
Early detection of Alzheimer's disease is essential to develop preventive treatment strategies. Detectible change in brain volume emerges relatively late in the pathogenic progression of disease, but microstructural changes caused by early neuropathology may cause subtle changes in the MR signal, quantifiable using texture analysis. Texture analysis quantifies spatial patterns in an image, such as
Objectives: To investigate factors associated with multiple induced abortions. Materials and methods: A multi-centre cross-sectional survey among abortion-seeking women (n = 623;14-47y) in Sweden, 2021. ‘Multiple abortions’ was defined as having had ≥2 induced abortions. This group was compared to women with a previous experience of 0-1 induced abortion. Regression analysis was conducted to determ
This chapter exemplifies rodent models of Parkinson's disease that have been used in transplantation studies and recounts basic transplantation methods. It describes morphological features of grafts containing dopamine neurons and focuses on the role of nigral grafts that are implanted homotopically in the mesencephalon, for example, near their location in the normal brain. The neurotoxin 6-hydrox
Skin is attractive for drug therapy because it offers an easily accessible route without first-pass metabolism. Transdermal drug delivery is also associated with high patient compliance and through the site of application, the drug delivery can be locally directed. However, to succeed with transdermal drug delivery it is often required to overcome the low permeability of the upper layer of the ski
With recent advances in wireless technologies, wireless LANs are becoming increasingly widespread as an alternative to fixed access technologies. The IEEE 802.11 standard has gained the most popularity among the different standards and is currently being deployed both within enterprises as well as being used for public access. One of the weaknesses of the basic medium access in the 802.11 standard
The availability of standard protocols to obtain DNA sequences has allowed the inference of phylogenetic Hypotheses for many taxa, including moths. We here have inferred a phylogeny using maximum-Likelihood and Bayesian approaches for a species-rich group of moths (Erebidae, Arctiinae), with strong emphasis on Neotropical genera collected in different field campaigns in the Atlantic Forest of Braz
Climate change and its environmental consequences is a pressing global challenge, with the construction industry being a major contributor to carbon dioxide emissions. This has led to an increased interest in biobased insulation materials, such as hemp fiber and wood fiber, which offer more sustainable alternatives. However, questions arise regarding their fire performance, particularly when repl
Denna uppsats behandlar det straffrättsliga begreppet vilseledande i kontexten av brottet svindleri enligt 9 kap. 9 § brottsbalken, med särskilt fokus på tillämpningen i det uppmärksammade rättsfallet mot Birgitte Bonnesen, tidigare verkställande direktör för Swedbank. Trots svindleribrottets långa existens i svensk rätt och dess potentiella samhällspåverkan, har rättspraxis varit förhållandevis bThis thesis addresses the criminal law concept of misleading in the context of the offence of fraudulent conduct (Swedish; svindleri) under Chapter 9, Paragraph 9 of the Swedish Penal Code, with a particular focus on its application in the high-profile legal case against Birgitte Bonnesen, former CEO of Swedbank. Despite the longstanding existence of the offence of fraudulent conduct in Swedish la
Bakgrund: Ikea har under en längre tid upplevt problem med felaktiga kapaciteter registrerade i deras system. Idag finns det inget gemensamt arbetssätt för att registrera och uppdatera kapacitetsinformation och därför reflekterar inte informationen i systemet leverantörernas verkliga kapaciteter. Detta gör det svårt för företaget att kunna ha en överblick över kapaciteterna och hur de är allokeradBackground:IKEA has, during a long time, experienced problems with incorrect capacities registered in their system. There is no standardized way of working with registering and updating the information regarding capacity today. Therefore, the information regarding the suppliers’ capacities does not reflect the reality. Furthermore, the company does not have a clear picture of how the capacities ar
Popular summary Energy generation from renewable sources is one of the main issues to be solved for the 21st century. One of the most advanced technologies currently available is wind energy, which has a large potential onshore and offshore. However, in many cases wind energy is restricted to large wind parks with wind power plants sometimes exceeding heights of 100 m. The construction of large wi
Search engines have become a starting point to the Internet, and for the large majority, Google Search is the preferred choice. Research shows that users perceive search engines as neutral tools, or neutral platforms of information, when in fact search results per definition are ranked according to many different principles and regulations. Therefore, search engines are important gatekeepers of th
During a changeover, that is when the tools in a machine are replaced so that it is able to manufacture another product, no other products can be manufactured and therefore the company looses money. To minimize this loss the production is often organized with big batches to minimize the amount of changeovers. A consequence of this is that the stock of WIP-products (Work In Progress) increases and
As part of both the sharing and social economies, libraries of things (LoTs) can play a role in reducing consumption in a socially sustainable way. They have the potential to overcome key sustainability and service shortcomings of other circular and sharing business models (BMs), but research on LoTs is sparse. Because of this potential, this research aims to improve the understanding of LoT BMs t
I takt med att internet har börjat att växa har allt fler näringsidkare börjat att använda sig av sociala medier som plattform för att marknadsföra sin verksamhet. En viktig aktör på sociala medier är influencers och en ny marknadsföringsmetod som har utvecklats på internet är ’influencer marketing’. Allt eftersom influencer marketing som marknadsföringsmetod har ökat i stor omfattning ger det uppAs internet has started to grow, more and more tradesmen have started to make use of social media as a platform to market their businesses. A major user of social media are influencers and a new marketing model called influencer marketing has been developed on the internet. As this marketing model has grown in importance, questions arise whether the identification of advertising requirement in 9 §
Det akuta behovet av att mildra klimatförändringarna har lett till utvecklingen av strategier för att minska utsläppen av växthusgaser. Carbon Capture and Utilization (CCU) har vuxit fram som en lovande teknik som inte bara syftar till att fånga upp koldioxidutsläpp (CO2) utan också använder den infångade koldioxide för att skapa produkter, och därigenom tillhandahålla en potentiell väg mot hållbaThe urgent need to mitigate climate change has prompted researchers to investigate novel strategies to reduce greenhouse gas emissions. One promising technology that might ease the way for sustainable and circular economies is carbon capture and utilization (CCU), which not only captures CO2 emissions but also uses them to produce valuable products. This thesis investigates the potential of CCU i
Ända sedan 1800-talet har det stått klart att för den som vill utforma termodynamiska processer finns det oundvikliga kompromisser. Bland de främsta av dessa är att för en värmemotor måste man välja mellan kraft eller effektivitet: en kraftfull motor kan inte vara effektiv, och en väldigt effektiv motor kan inte vara kraftfull. Detta var länge accepterat som en oundviklig konsekvens av termodynamiWe investigate the validity of thermodynamic uncertainty relations (TURs) in a strongly correlated quantum dot system operating in the Kondo regime. TURs place fundamental bounds on the trade-off between precision and dissipation in non-equilibrium systems, and while these bounds are rigorously proven for classical stochastic dynamics, they are not guaranteed to hold in quantum-coherent, strongly
In the northwest of Skåne, a peninsula stretches out and tapers off out into the ocean. This is Kullahalvön, a stronghold of contrasts that swings between the dramatic and romantic. Its edge rises from the sea like armor: shaped by weather and protective of all the landscape that rests behind it. Forests, meadows,fields and beaches overlap between the old fishing villages that have grown into town
