Traditional mean-variance optimization of portfolios has received much criticism due to its inability to account for higher order moments and non-quadratic utility. In this thesis, the topic of portfolio optimization is studied using the Atkinson index with CRRA utility. We construct Atkinson-efficient portfolios using computer-generated data in Monte Carlo simulations, as well as using financial

The increasing concern on the present and future impact of climate change has raised the attention on the relationship between technology and the environment. The aim of this paper is to investigate the impact of green innovation on carbon emissions. Carbon dioxide (CO2) and Greenhouse Gas (GHG) emissions per capita are used as a proxy for environmental quality. Technological innovation is measure

The latest global financial crisis ignited the debate on whether the role of monetary policy's main objective, price stability, is enough to achieve financial stability. It also sparked an interest of new policy measures that directly targets the financial system, such as macroprudential policies. In this study, we empirically investigate how monetary and macroprudential policies interact to a

In recent years, the field of mass spectrometry (MS) has grown significantly, allowing for shotgun proteomic experiments to be used increasingly in biomarker discovery experiments. However, using standard methods of MS not all peptides present in a sample may be identified. To combat this, a procedure termed alignment, or match-between-runs, is used to propagate identifications from one run to ano

Stadsteatern består av två delar, där Del 2 är en tillbyggnad till den gamla byggnaden som benämns som Del 1. Hela bygganden består av

Empathy is a phenomenon known by many definitions in the positive sense. The concept is mentioned as one of the three most important components within social work. At the same time, the concept of empathy is elusive and oftentimes difficult to pinpoint in the everyday social work practice. The aim of this study is to explore how social workers who work directly with vulnerable groups define and re

Mounting cameras on motorized objects has become possible in greater extent due to the emerging camera technology during the past few decades. This application could prove useful in several areas such as search and rescue operations, surveillance or even news monitoring. One hardship that this brings is the difficulty of keeping the camera unit stable while its setting is not. In the situations me

The link between income inequality and economic growth has been a popular topic in the empirical research literature in the past decades. Despite that, a consensus is yet to emerge. This paper analyzes the effect of income inequality on economic growth and the role of institutions in mitigating potentially negative effects using a panel of 48 countries in the time-period 1977-2009, including a mix

The aim of this paper is to evaluate a machine learning technique, Random Forest, to predict default rates for banks in the United States. This study extends the findings of a Random Forest model first introduced by Petropoulos et al. (2017) by extending their model by evaluating a longer sample period and adding macroeconomic variables to analyze how current market conditions impact the predictio

I denna rapport så har matsalar i fyra skolor observerats genom ett FAMM ( Five aspect meal model) perspektiv. Vegetabilisk kost har börjat prioriteras i olika kommuner i Skåne. Fördelarna med vegetarisk kost är flera, det är miljövänligare, hälsosammare och billigare än kött. Livsmedelsverket rekommenderar att öka andelen vegetabilier och minska andelen kött samt att lunchen bör ha minst ett veg

This research has been conducted through a single case study by applying a qualitative research approach on how a university context shapes the way entrepreneurs learn in an incubator. The data was collected through semi-structured interviews and analyzed according to Gioia, Corley and Hamilton (2012). Literature regarding Entrepreneurial Learning through an Experiential and Social Learning Theory

Automated Twitter accounts, or Twitter bots, have gained increased attention lately. In particular, a novel type of bot, so called social bots, are piquing peoples’ interest, as these bots have recently been involved in a number of political events. Most of the previous work on how to detect bots has not distinguished between such novel bot types, and other, less sophisticated ones. Instead, they

De svenska tillverkarna av ultralätta mikroflygplan, Blackwing Sweden AB, har lämnat en förfrågan gällande uppdatering av den justerbara mekanismen tillhörande roderpedal-systemet i flygplansmodellen BW600RG. Det nuvarande manuella systemet anses bristfälligt sett till den icke ergonomiska justeringsprocessen som för övrigt kräver att flygplanet är stationärt. Målet med detta projekt var att framfThe Swedish ultralight aircraft manufacturer, Blackwing Sweden AB, has requested a reinvention of their adjustable mechanism for the rudder pedal system in the BW600RG aircraft. The current manual system is insufficient in terms of a non-ergonomic adjustment process which requires for the aircraft to be stationary. The ambition of this project was to deliver a concept covering a fully automated ad

This master thesis examines the valuation of FinTech and Dot-Com companies by looking at the underpricing level of initial public offerings (IPOs) and the abnormal returns during the period surrounding the announcement date of merger and acquisitions (M&As). The sample consists of 234 IPO’s observations from 1995-2019 and 58 M&A’s deals from 2000-2019. The results suggest that the underpri

Previous research shows that gambling addiction receives less attention in Social services compared with substance abuse. The aim of the study was to compare the child-welfare officer’s view on problem for the child and also on support and assistance for children who grow up in families where parents are compulsive gamblers than in families where parents have a substance abuse (in this paper it wi

Syftet med denna studie har varit att undersöka skönlitteraturens funktion i läromedel i svenska och huruvida kunskapskravets term centrala verk sammanfaller med kanoniserad litteratur. Specifikt har tre läromedel som säger sig täcka hela gymnasiekursen Svenska 1 undersökts: Svenska 1 helt enkelt (2018, NA-förlag), Språket och berättelsen 1 (2015, Gleerups) samt Formativ svenska 1 (2017, Liber). S

Hur förhåller sig hållbara fonder till investeringar i animalisk kost? Fonder och andra aktörer som är involverade i hållbara investeringar intervjuades kring hur de förhåller sig till animalisk kost. De utesluter alla verksamheter så som fossila bränslen, uran och GMO. Synen på animalisk kost var emellertid inte samstämmig utan visade på en mångbottnad syn där alla aktörer hade sin egen uppfattAnimal source foods have been targeted in a wide range of literature, highlighting the business as a major driver of climate change and biodiversity loss. This study shows how actors involved in sustainable funds approach animal source foods and how they regard the business as a potential selection criterion. Drawn on Maarten Hajers argumentative discourse analysis storylines where identified. In

Konventionell lungröntgenundersökning är en vanlig undersökning på en röntgenavdelning. Kommunikationen där är en viktig del i att främja en god och patientsäker vård. Ökad invandring kan medföra att fler språkskilda möten sker inom vården. Röntgensjuksköterskan ansvarar för främjandet av kommunikationen. Syftet med studien var att beskriva röntgensjuksköterskors upplevelser och erfarenheter kring

The payday lending industry in Michigan grew rapidly in the first decade of the 2000s, providing high-cost loans to borrowers with a damaged credit history and few other financial options. The typical clientele of payday lenders represents a specific socioeconomic demographic, wherein they are most often the ‘working poor’. Certain demographic variables may influence the likelihood that a person w
