Teoretiska fysiker tycker verkligen om att bygga modeller av sin omvärld för att kunna göra förutsägelser om den. En av de mest lyckade teoretiska modellerna är standardmodellen inom partikelfysik. Med den har fysiker lyckats förklara och förstå hur universums allra minsta beståndsdelar fungerar. Den har till och med vid ett flertal tillfällen lyckats att förutsäga existensen av nya partiklar, somIn recent years, the BaBar, Belle and LHCb experiments have observed an excess of $B\to D^{(*)}\tau\nu$ decays compared to Standard Model predictions. In this thesis, we investigate if it is possible to explain this excess with a two Higgs doublet model using the Froggatt-Nielsen framework. Two Higgs doublet models allow new decays at tree-level and the Froggatt-Nielsen mechanism gives an explanat

I takt med den växande digitaliseringen förändras förutsättningarna för arbetslivet och medarbetare ställer nya krav på sina arbetsgivare. Arbetet med Performance Management behöver förnyas för att möta framtidens behov. För att öka förståelsen för vad som får medarbetare att bli engagerade i sitt arbete, granskades IKEA och deras mål- och utvecklingsprocess. En elektronisk enkät skickades ut tillIn pace with the growing digitalization, the conditions for worklife and coworkers are in continuous change, which in turn changes the demands on the employees. The work with Performance Management needs to be updated to meet the requirements of the future. The purpose with this study is to achieve better understanding what makes coworkers engaged in their work in order to increase their performan

I och med min utbildning till lärare i musik- och svenska som andraspråk vill jag låta dessa ämnesområden sammanfläta i mitt examensarbete. I och med den flyktingström som påverkat hela vårt land har skolsituationen i Sverige förändrats. Antalet nyanlända elever i skolan har ökat och många av dem ska få undervisning i musik. Detta är ett uppdrag som musiklärare inte varit beredda på. Därför är syfIn my education, to be a teacher in music and Swedish as a second language, I want these subjects intertwine in my degree project. With increase of refugees in our country, the school situation has changed. The number of new arrivals in school has increased and many of them will be taught in music. This is an assignment that music teacher has not been prepared for. Therefore, the aim of the study

We contribute to the holistic picture of the phenomenon SCE by adding an interpretative perspective, allowing us to critically challenge five assumptions that theoretically underlie its conceptualization. We challenged SCE’s assumptions that: employees have a common understanding and perception of sustainability and CE; that these understandings are in line with SCE theory; that the three dimensio

Kvalitetsmärkning av begagnade produkter i den svenska IT-sektorn Hur kan vi konsumenter lita på, att en begagnad produkt håller en tillräckligt hög kvalitet, för att vi ska välja att köpa den istället för en ny? Ibland är det tillräckligt att titta på en vara för att kunna bedöma kvaliteten men i vissa fall, så som elektroniska produkter, är det betydligt svårare för konsumenten att göra en bedDue to the depletion of earth’s resources and the growing concern of electronic waste it is important to extend the lifespan of electronic products. Consumers often have the perception that re-used and remanufactured products are of lesser quality than new counterparts. This study aims to evaluate if a more comprehensive sustainability certification scheme for electronic products, covering criteri

F¨or att undvika ekonomiska kriser likt den 2008 beh¨over finansinstitut bra modeller f¨or bland annat obligationspriser och kreditindex. Genom att anv¨anda skillnaden i r¨anta mellan riskfria och riskfyllda obligationer kan dessa modelleras och s¨akra att bankers och f¨ors¨akringsbolags tillg˚angar r¨acker vid tider av ekonomisk turbulens. Ett kreditindex ¨ar ett index som best˚ar av f¨oretagsobliThis thesis proposes an autoregressive credit spread model to make long term simulations of credit spreads and credit indices in the Investment grade and High yield bond segments. Several models are tested, and the final spread model produces simulations with statistics consistent with historical data, even though the model itself is relatively parsimonious. A transition from spread to index is pro

Social service workers documentation and emotional labour – a qualitative study about working with documentation The aim of this study is to explore the experience among social service workers in regards to working with documentation and to analyze how it affects their ability to perform emotional labour. Former research has shown that social service workers spend a big part of their work day wor

Data har många användningsområden inom både forskning och industri. I detta examensarbete skapades en platform som självgående kan användas för att samla in stora mängder data från omgivningen.Everyone who has worked with research knows how rewarding experimenting and developing new algorithms can be. However in some cases, the hard part is not the invention of these algorithms, but their evaluation. To try and make that evaluation easier, this thesis focuses on the collection of data that can be used as positional ground truths using an autonomous measurement platform. This should assi

The use of cloud computing is increasing in many different areas, and one of these areas is education. As using cloud in education becomes standard in many schools, some ethical concern regarding student information arises. This thesis aims to identify the issues that Swedish schools in the region of Skåne are facing regarding the use of cloud computing. This is achieved by creating a theoretical

The performance of five commercial available biobased packaging films for fully-baked frozen bread was studied in comparison to polyethylene (PE) film. The main purpose of this study was to understand how biobased packaging materials affect the quality of fully–baked frozen bread. The five biobased packaging films evaluated in this study were biobased polyethylene (bio-PE), Biodolomer®, polylactic

This paper examines how the exchange rate affects Chinese economic growth. First, we go through the literature about exchange rate and how it affects the economic growth. We respectively analyze the transmission mechanism of RMB real effective exchange rate on the impact of Chinese import, export and foreign direct investment. We use the quarterly data from 1994 to 2016 and the method of cointegra

This work will examine how the British government engaged with Muslim-led organisations through its counter-extremism strategy Prevent in following the London bombings in 2005. Over a period of seven years two governments, Labour and the Coalition, implemented separate version of Prevent which led to distinct forms of state engagement with Muslim-led organisations. By looking at the broader histor

Det finns många exempel på att använda teknologi i skolan för att förbättra elevers lärande. En relativt oanvänd teknologi i utbildning är Virtual Reality. De flesta VR applikationer som används i utbildning idag är passiva virtuella studiebesök, där användaren interagerar med applikationen genom att observera den virtuella världen. Detta examensarbete undersöker om interaktiva Virtual Reality appThere are many examples of using technology in schools for enhancing student’s learning experience. A relatively unexplored technology in education is Virtual Reality. Most of the existing VR applications aimed at learning are passive virtual field trips, where the user only interacts with the application by observing the virtual world. This thesis explores if interactive Virtual Reality applicati

Syftet med denna studie var att undersöka om vissa personlighetsdrag korrelerar med vissa delar av social intelligens. Då både social intelligens och personegenskaper är breda begrepp så valdes inom social intelligens en avgränsad del att undersökas, nämligen förmågan att identifiera emotioner och förståelse av de bakomliggande orsakerna till emotioner. Inom personegenskaperna valdes Big Five teorThe purpose of this study was to examine whether there was a correlation between some Personality Traits and parts of Social Intelligence. Since both Social Intelligence and Personality Traits are broad constructs it was decided to narrow down what was examined. The Ability to Identify Emotions and Understanding the Underlying Causes of the Emotion was specified for Social Intelligence. The Big Fi

Swedish transport administration has over the past few years changed its way of purchasing contractors. The new way is totalentreprenad, which gives the contractor the opportunity to develop and renew the construction methods. Stabilization is one of the outcomes of that development. It is an unusual method in Sweden and therefore it is important to learn more about its characteristics. Analyses o

The aim of this study is to shed light on today's witness situation. People are not willing to testify in court because of the fear of threat and pressure from criminal gangs. Because of this, we have examine how anonymous witness can increase the witness tendency among individuals with former criminal background. Anonymous witness is a suggestion from political parties in Sweden to become a l

In today’s society people are influenced by technological developments. Technology changed the consumer’s behavior, but also the way companies evolved over time. Nowadays, technology is accessible for everyone, which leads to fast changing environments with a lot of competition. There are limited studies that focus on teams of new ventures in comparison to the lone entrepreneur. However, there are

This thesis aims at developing and evaluating a model for high frequency foreign exchange data, that beats the TWAP benchmark the majority of the time. This is done by dividing the total order time into smaller time buckets and trading a smaller quantity of the total order volume in each bucket. The second purpose of the thesis is to determine if there is an optimal bucket size in which to trade i
