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

Background: Health is unevenly distributed within and among the countries of the world, and usually follows a population’s socio-economic status. The lower this is, in comparison to others’, the poorer the health. Romania is one of the poorest cou

Many university students feel that their sexual activity is either not sufficient or that it is too high. This leads to dishonesty and discomfort concerning the subject when it is discussed. This can be seen as a sign of conformity. The goal of this quantitative study was to explore a possible correlation between conformity and sexual activity in two university programs at Lund University, Sweden.

Ekonomin i Kina har blomstrat över de senaste tiotal åren, och tillsammans med det skyhöga antalet invånare, strävar landet nu efter att uppnå världens största medelklass. Men för att Kina och hela världen skall kunna upprätthålla en levnadsstandard likt den vi har i väst, så kommer vi göra det på stor bekostnad av klimatet. Huvudsakligen sker det på grund av den massiva förbränning av kol och fosMeteorological conditions are influenced everyday by air-bound aerosols and pollution in the atmosphere, and understanding these processes from micro to synoptic scale, is essential for forecasting and creating high resolution weather models. In this study, three different experimental weather models are analysed to provide some understanding on how various meteorological parameters are influenced

With the events of 2015, commonly referred to as the refugee-situation, a light has been cast on various European Union member states’ handling of asylum seekers. In relation to overall stricter procedures, the Swedish state has proposed a series of restrictive policies to cope with the situation.

Vår galax, Vintergatan, innehåller bortåt 200 miljarder stjärnor av varierande åldrar och storlekar. Under en mörk och klar natt kan man se ungefär 2000 med blotta ögat. Detta är en liten del av det stora hela, men tillräckligt för att stimulera människors nyfikenhet. Vad är de gjorda av, och varför är de där de är? Enkla frågor, som har väldigt komplexa svar. Genom att kartlägga strukturen och deContext. Large scale chemical abundance gradients in the Galactic disks, small-scale abundance structures, and the mean chemical abundance values in the Solar vicinity, are important constraints to Galactic chemo-dynamical formation and evolution models. The formation and evolution of stars, and interstellar gas and dust depends on the distribution and evolution of matter in the Galaxy. Therefore,

Menstruation is a normal body function and a sign of reproductive health. Although it is a fundamental human right for girls and women to have the ability to properly manage their menstruation, it is a long-neglected issue in low-income countries. Pilot studies have provided optimism for the menstrual cup’s potential to improve the quality of life for Ugandan girls and women. Several actors are in

Delningsekonomins vinster – lever konceptet upp till vad som utlovas? Att dela tillgångar med sina nära och kära är inte något nytt, men under 2000-talets början har delandet förändrats. Delningen har blivit mer storskalig, och alltfler individer delar tillgångar som de inte använder med främlingar. Detta benämns som delningsekonomi; istället för att köpa en produkt införskaffar individen tillfäDuring the last decade, a new type of economy has emerged: the sharing economy. Sharing no longer occurs among the closest circle of acquaintances but between strangers, using underutilized resources among one another. This have led to a rise of collaborative initiatives. Previous research show that these initiatives are rarely evaluated, and there is yet no best-practice assessment model. The aim

Historical data shows a strong relationship between hourly changes in CDS index iTraxx Main and equity futures EURO STOXX 50. We hypothesize that the relatively stable relationship should allow us to trade the two markets. A Markov regime switching model is introduced, distinguishing cointegrated regimes that allows the cointegration relation ship to be switched on and off. A pairs trade between th

A diversity of risk management approaches are suggested by researchers and followed by organizations in order to minimize the failure rate and ensure project success. However, does risk management do always what it is supposed to do? In this research, we survey field workers and interview project managers, to investigate the influence of ri

Förhållanden i och runt Segeå i Skåne har undersökts teoretiskt för att kartlägga möjligheten att främja förekomsten av stormusslor där. Ån är i högsta grad påverkad av det odlingslandskap som omger den, med övergödning som en av följderna, och är ofta väldigt grumlig. Musslor är filtrerare och livnär sig på växtplakton, som bildas i större utsträckning i näringsrika akvatiska miljöer. VäxtplanktoIn this study Segeå has been valued to consider possibilities of increasing the amount of mussels as effective filterers in the creek. The purpose would be to reduce high levels of nitrogen and phosphorus; a result of the agriculture in the area. Mussels filtrate water in search for nutrition, and bind nitrogen and phosphorus in their bodies. Using rapports from mussel projects, contacts on count

The aim of this study is to explore the importance of a diagnosis when it comes to gaming addiction.

The empirical material is analysed from a social constructive perspective to shed light upon how gaming addiction has come to be defined in differen

Energiproduktion, precis som övrig produktion, påverkar miljön på olika sätt. Fossila bränslen orsakar växthusgasutsläpp, vattenkraftverk och speciellt utbyggnad av den orsakar skador på naturmiljön, och kärnkraft med hanteringen av radioaktivt avfall innebär stora risker. Genom att öka energieffektiviteten kan sådan påverkan minska. Dessutom kan säkerheten i energisystem öka och bättre kontroll öEnergy generation and the use of energy is associated with environmental impacts. It is imperative to reduce energy consumption – for a better environment, energy security and a more competitive industry. The Swedish government has set goals to increase the energy efficiency with 20 % and reduce greenhouse gas emissions with 40 % by 2020. The ‘energy efficiency gap’ is a concept describing the di
