Den främsta anledningen till att barn genomför röntgenundersökningar är på grund av en akut skada. Många av barnen upplever en röntgenmiljö som skrämmande vilket får dem att uppleva oro och rädsla Detta är en litteraturstudie som belyser barns oro och rädsla i samband med en röntgenundersökning och fokuserar på barn mellan fem till 15 år. Sju vetenskapliga artiklar inkluderas i resultatet och via

The current healthcare system in Sweden suffers from major problems when it comes cost-efficiency and delivery of healthcare services. Unsustainable increase in healthcare cost over the past few decades has led to that Government funding is no longer keeping pace with increasing demand and complexity. There a several ways to address this issue, one is to implement a new healthcare delivery model w

This study aims to investigate whether investing in environmentally friendly companies has a positive effect on risk-adjusted returns. We construct two portfolios: one portfolio consists of the 100 highest ranked companies from Newsweek’s yearly green rankings from 2017, and one portfolio consists of 122 companies that 2018 are blacklisted for environmental reasons by four asset managers: Nordea,

This thesis aims to increase the understanding of multi-stakeholder initiatives (MSIs) as means for the Swedish apparel industry to enhance their sustainable supply chain management (SSCM). Three MSIs that address environmental issues in apparel supply chains are explored as cases – Sustainable Apparel Coalition (SAC), Sweden Textile Water Initiative (STWI), and Textile Exchange (TE), focusing on

Börja med resterna för att minska matsvinnet från skolköken Skolköken kan fortsätta minska sitt matsvinn genom att först fokusera på att tillvarata rester och därefter minska överproduktionen. På så sätt kan engagemang väckas och varaktig förändring uppnås. Varje år slängs stora mängder mat. Matproduktion påverkar miljön och ju senare i värdekedjan desto större påverkan har skett. Att minska matOf the food produced for human consumption, one-third is lost or wasted. Food waste has an impact on the environment in several ways and it is thus required to reduce food waste in all parts of the value chain. The objective of this thesis is to identify drivers and barriers for implementing food waste reducing strategies in school kitchens. The study is conducted within the project Göteborgsmod

This paper breaks new ground by employing a VECM approach to investigate the relationships between TFP and five other variables in China during the period 1980-2014. Even though the method is commonly used in other research, it is absent in the literature covering Chinese TFP. The results indicate that the VECM is useful for this purpose. Granger causality and significant long-run relationships ar

Today, English is the most studied second language, being used in academia, international relations, social forums and mainstream entertainment, resulting in English becoming a common topic of research in the study of second language acquisition. One particularly interesting form of entertainment is the hobby of online digital gaming as English has become the de facto language used in absence of a

Overcoming drug resistance in breast cancer Breast cancer remains the most common malignancy in women worldwide with over 2 million newly diagnosed cases in 2018, accounting for almost a quarter of all cancer cases in women. More than 70% of breast tumors depend on estrogen for survival and growth, which led to the development of targeted therapy against the associated cellular hormone receptor

In 2009, Bitcoin was introduced to the world. Today, ten years later, there are still gaps in the research of how to model the cryptocurrency. In this thesis, the capacities of different volatility models to capture the high volatility of Bitcoin returns are investigated. The models used are GARCH-type models: GARCH(1,1), IGARCH(1,1) and GJR-GARCH(1,1). Jumps, or outliers, are also detected and fi

Med hjälp av MRT så är det möjligt att undersöka en hjärna utan att behöva använda skadlig strålning. Genom att korrelera vattenmolekylers diffusion med dess R2 värde så är det möjligt att separera olika sorters vävnad. Detta då dessa parametrar beror på den kemiska sammansättningen samt strukturen på omgivningen. Men för att kunna separera vävnaderna och visualisera dem så måste datapunkterna somMRI can be used as an non-invasive method to map the brain. By correlating diffusion with relaxation it is possible to separate different tissue kinds such as white matter, grey matter and free water. In this work we look at how to bin the data to best separate the tissues. By modifying the bin limits in Diso, Dperp / Dparallel, \DDelta and R2 it will be shown that there is not a single optimal

Female-limited colour polymorphisms provide interesting examples of intraspecific genetic diversity but, in most polymorphic taxa, we know little about the macroevolutionary origin and subsequent history of polymorphism during diversification. The damselfly genus Ischnura includes many species with multiple, heritable female colour morphs. The evolutionary origin of polymorphism in this clade is u

When two materials with different lattice constants are grown together, this generates stress between them, and therefore strain. This strain causes them to have different thermal and electrical properties, and this is especially important on the nanoscale where changes have large impacts. This project is intended to see if COMSOL can be used as a tool to model how materials respond to lattice mi

The current textile industry is among the most polluting industries and actions should be taken to decrease these negative impacts. One issue that should be addressed is the increasing amount of textile waste. Post-consumer textiles are often incinerated or downcycled due to many factors. In order to move towards a circular clothing system, businesses and policy makers play a major role. The purpo

Studiens syfte var att undersöka upplevelsen av stress hos individer med hög respektive låg grad av samvetsgrannhet. Semistrukturerade intervjuer genomfördes med sex deltagare som skattade högt respektive lågt på samvetsgrannhet. Materialet analyserades med tematisk analys och åtta teman identifierades. Dessa teman var: stressorer, stressreaktioner och stressymptom, coping, krav och kontroll, behoThe aim of this study was to investigate the experience of stress in individuals with high respectively low degree of conscientiousness. Semistructured interviews were conducted with six people who estimated high respectively low on conscientiousness. The material was analyzed using a thematic analysis and eight different themes were identified. The eight themes were: stress origins, stress reacti

Asset prices have had larger and more rapid increases since 1980 when compared to the post-war period, especially compared to the Bretton Woods period. In this thesis we test whether the excess elasticity view provides a plausible explanation for this change. The excess elasticity view, put forth by Borio and Disyatat (2011) and Borio and White (2003), argues that the financial system has become m

This essay is a discourse analysis focused on the revise of the swedish minority law (SFS 2009:724) that began with a committee directive in 2016 and resulted in a change of the law in January 2019. The purpose of the analysis is to examine whether an ongoing conflict surrounding the indigenous people Saami and their position as a minority in Sweden takes place in the revise, and if so, how the Sa

Selection on proteins during the transition to multicellularity The evolution of unicellular organisms into more complex, multicellular groups has been one of the most important transitions in life. One way of studying the molecular mechanisms involved in this transition is to quantify changes in proteins that have functions proposed to be important in the formation and coordination of multicellu

Syftet med studien är att utvärdera hur arbetet med målstyrning kan förbättras under produktionsskedet i byggbranschen. Studien har gjorts som en kvalitativ fallstudie baserat på tre byggprojekt i ett av Sveriges största byggföretag. Genom att intervjua anställda med olika roller i projekten samt ett antal högre chefer har olika arbetssätt och förhållningssätt kunnat utvärderas. Med bakgrund av de

Framtagandet av kontinuitetsplaner är inte systematiskt inom hälso- och sjukvården i Region Skåne. Därför har en vägledning utvecklats för att underlätta framtagandet av reservrutiner. Först utvärderades om vägledningen innehåller identifierade rekommendationer för kontinuitetsplanering. Därefter genomfördes en pilotstudie på en vårdavdelning för bestämning av dess användarvänlighet och användbarh
