Competition over reproduction – how does it affect the DNA? Competition over what is often a scarce resource -reproduction, is a phenomenon widely studied in science. It is the ultimate endeavor for life, ensuring that an individual’s DNA is carried on to the next generation, preserving its footprint in the shape of a child. This is a very selfish enterprise for many organisms which becomes appar
The process of firms entering and exiting the market has since Schumpeter’s introduction of the concept of creative destruction been a subject of interest for economists aiming to determine what drives economic growth. However, limited availability of data has long been a hindrance to such ambitions and it is not until recent decades that empirical studies on the role of firm dynamics for economic
This paper uses a bivariate BEKK model to estimate volatility spillover effects between stock and bond markets for the Nordic countries Sweden, Denmark, Finland and Norway. Daily log returns between the years 2001 and 2018 are analyzed. No spillover effect from the bond to the stock market is found in any of the countries which is a result that is unusual compared to a large part of the preexistin
Förändringar av miljöförhållanden i två naturområden i Helsingborg Landskap förändras hela tiden och det sker många stora förändringar genom att vi brukar marken på olika sätt, som till exempel när vi odlar mat. Under det senaste århundradet har det skett många stora förändringar i jordbrukslandskapet, bland annat på grund av att man börjat använda konstgödsel, bekämpningsmedel och har utvecklat Since the 1800’s the agriculture has changed and intensified significantly, going from small scale farming to large homogenous arable landscapes with fewer grazing animals, more fertilizers and pesticides. In Sweden, this pattern of intensification has been very distinct, especially in Scania, which today is dominated by plains. This has left substantial changes in the surrounding ecosystems, affe
Sex matters! It is natural to ask questions about where the species of this planet come from and how they become what they are. As a matter of fact, development of new species is in process all the time. Somebody named this process speciation. Like language which enables us to guess where the people might come from, some traits make it possible to recognize the individuals from the same populatio
Diel vertical migration (DVM) is performed by various zooplankton taxa. The general movement pattern of DVM has been well studied while the possible clonal differences of this movement largely remain unknown. My master thesis focus on investigating the effects of environmental stressors on Daphnia magna strains isolated from natural populations. Here I maintained 11 strains of Daphnia magna origin
Sanction evasion can hamper the effect of international sanctions. This paper aims to establish whether the Russian sent counter-sanctions were evaded by the Western countries by using non-sanctioned countries as transit routes for the sanctioned products. This question is analysed by estimating a gravity equation of trade by applying Pseudo-Poisson Maximum Likelihood and Ordinary Least Squares es
Människokroppen är uppbyggd av olika typer av celler som exempelvis hudceller, nervceller och fettceller. Generellt sett är dessa celler utformade för en väldigt specifik uppgift såsom att utföra arbete (exempelvis muskelceller) eller att förse kroppen med struktur (exempelvis benceller). Det finns en väldigt spektakulär typ av cell -- så kallade stamceller -- vars specifika syfte är att omvandlasThe generation of induced pluripotent stem (iPS) cells from differentiated cells is a process of great scientific interest due to the medical potential of such cells. This process (called 'reprogramming' of cells) is however notoriously inefficient and still not very well understood. Therefore studies that can help us understand the interactions and mechanisms governing the reprogramming p
The purpose of this study was to analyze how does China pursue its national interest in the governance of the Lancang- Mekong River in domestic and international terms. The analysis was done through the lens of the classical realism theoretical school. Drawing from this framework and adopting the concept of national interest, the study gave a deeper understanding of China‟s motives behind the Lanc
Invasive alien species are organisms that have been introduced to an area outside their natural distribution range and threatens animals, habitats or humans in the new area. The raccoon (Procyon lotor) is a mesopredator originating from North and Central America that has been introduced in Europe and Asia. Since the first European introductions of raccoons in Germany, natural dispersal and pet tra
Tamoxifen is the most common choice of anti-cancer drug for breast cancer in pre-menopausal women. Tamoxifen antagonizes the estrogen proliferative effect by interacting with estrogen receptor. Despite the fact that this treatment has showed a tremendous effect on the survival of patients, resistance to the treatment frequently occurs. Several mechanisms of tamoxifen resistance have been already d
I got to know the city of Dujiangyan during my semester in Sustainable Urban Dynamics. I was fascinated by it because it stood out from the image of China I had in my head. Dujiangyan is one of the greenest cities in China, pollution level is much lower than the average, people are living longer and they are known to be laid-back and relaxed. During my site visit I found Dujiangyan to be a city
This bachelor thesis, “There is nothing hidden behind the mask, the mask is all there is.’ - A netnographic study on influencers’ authenticity and the communication of fashion through YouTube”, aims to understand the conception of authenticity and identity from a fashion perspective through the phenomenon vlogging on YouTube. By applying a netnographic research design, this thesis contains a colle
This paper examines multidimensional poverty and the effectiveness of microfinance loans in alleviating it using household survey panel data on Bangladesh. Microfinance is an innovative method to financial development of the poor, yet controversial. Several studies investigate this subject matter from a single-dimensional perspective, although, it is generally known that the primary concept of pov
Violence in general, in Sweden is decreasing, but a specific type of violence, firearm violence among some young men, is increasing. This study is based on acts of violence occurring in the city of Malmö, which has become a symbol of firearm violence in Sweden. By studying social, subcultural and contextual factors, this essay examines the development and the meaning of firearm violence in Malmö.
Stock return volatility is very high in the biotech industry opposed to other industries and there is limited explanation as to why. Biotech companies invest large amounts of money on research and development to move drugs forward in the clinical trial phases, to get market approval by the regulatory agency FDA. The drug discovery and development process is long and expensive, taking on average 12
This thesis explores the Chinese lifestyle migration practice in Jutland of Denmark as a contribution to expanding the categories of Chinese new migrants. The study analyzed ten in-depth interviews on the lifestyle migration practice with Chinese migrants in Denmark. The purpose of this study was to deepen the understanding of the motivations and experiences of Chinese migrants in seek of a better
In the tumor microenvironment, Cancer-Associated Fibroblasts (CAFs) are the most represented cell type. Research has shown increasingly the key role of CAFs in cancer growth and evolution, creating the need to identify more clearly and further characterize the CAF population. In this study, looking at single cell RNA sequencing of 768 CAF transcriptomes, we define transcriptionally distinct subpop
Status, det socialt konstruerade relativa och relationella värdet på självet, ges och fås i social interaktion. Studiens teoretiska utgångspunkt är att individens sociala interaktioner utgörs av en kontinuerlig kamp för att vinna, eller mot att förlora status och att individer som deltar i mediaintervjuer och berättar om sitt liv gör detta för att upprätthålla eller höja sin sociala status. Det fe
Since the middle of the nineties, the amount of Regional Trade Agreements has risen sharply. This have created more opportunities for countries to join world trading and be more connected to the rest of the world. However, each trade agreement is unique and it is therefore interesting to evaluate if there are factors that are more important than others. This paper will be looking at combined GDP a
