This paper presents a stochastic model for Meningococcal disease. Mathematical models for diseases are an important tool in population dynamics, and their results carry real-world implications as they guide policies and vaccination strategies. While the systems being modelled are generally stochastic in nature, deterministic models are often used, possibly to the detriment of accuracy. In this pro

The development and consumption of functional food are increasing. To meet such an increasing demand, vegetable milk extracted from quinoa and fermented with lactic acid bacteria can offer an excellent alternative to fermented dairy milk which has a high nutritive value and is free from lactose, gluten and cholesterol. This research aims at: (a) isolating and identifying the autochthonous microbio

Den här uppsatsen studerar hur aktiv förvaltning förhåller sig till avkastning och avgifter inom det svenska premiepensionssystemet. Som mått på aktiv förvaltning har framförallt active share men även tracking error använts. Resultatet visar på att aktiva fonder presterar bättre än passiva fonder och att de fonder med högst active share presterar klart bättre än index. Vidare har inga samband mell

The aim of this thesis is to identify characteristics on how safety facilitators can improve inter-organizational learning from safety investigations. The study is a response to the fact that the Dutch Safety Board questions the learning effects of its accident investigation reports, despite that these are freely accessible on the website, which assumes that other organizations can use and learn f

Since EU’s expansion to incorporate former Communist countries, attempts to solve the so-called “Roma issue” spurred an unprecedented array of policies, interventions and measures at national and transnational level. Instead of the expected positive changes, discrimination and poverty worsened. The current migration waves, economic crisis, and the surge of far-right nationalism, contributed to an

In the Tanzanian district of Karagwe the NGO KADERES is working with agricultural development. In relation to this they produce fair trade coffee obtained from local farmers. Coffee husks are created as a waste product from the plant and are currently not used for any purpose. Instead they are left outside the factory. The propose of this project is to find a way to create briquettes from these hu

In this thesis I set out to investigate how Taiwanese elite students experienced their upbringing. I do so by developing my own concept, Single Path, and use Susanne Bregnbaek’s utilization of the concept Aporia. I apply them in order to answer how Taiwanese elite students negotiate their self-cultivation process in relation to the single path. I found that one of their most prominent existential

In a time shaped by an increased level of globalization and transnationalism, our perception of the immediate ‘local’ and the more distant ‘global’ is becoming more and more challenged by the forging of transnational flows, bonds and networks evolving in a rapid pace across profound distances. The new social, political and economic opportunities deriving from such transnational connections have be

This thesis is a response to the highly debated judicial decisions regarding separation surgery of conjoined twins. As separation surgeries often result in the death of one or both twins due to a medical condition, the question whether there is a legal justification for separation is controversial among scholars.

In this paper I investigate the relation between corruption and press freedom, perceived press freedom and the difference between press freedom and perceived press freedom as well as the causality of corruption on press freedom. My hypothesis is that corruption has a negative effect on both press freedom and perceived press freedom but that a higher level of corruption tends to make people believe

The aim of this master thesis was to examine the leisure travel conditions of children and adolescents. Results from The Swedish national travel survey 2011-2014 shows that journeys to leisure activities represents a great portion of the total travel and a significant share is made by car. Former research implies that active transport among youth improves physical and mental health, increases inde

This master’s thesis focuses on pedagogy and aspects of learning and remembering within guided museum tours for people with dementia. We explore in what way learning and remembering are focused on and triggered during those tours and with the help of which pedagogical means. Furthermore, we discuss what place these tours have within the museum as an institution. In order to examine our questions a

Syftet med det här arbetet är att undersöka hur den forskning som tilldelats Sveriges Riksbanks pris i ekonomisk vetenskap till Alfred Nobels minne förhåller sig till den allmänna samhällsutvecklingen och hur detta kan förstås utifrån sociologisk teori. Tre frågeställningar ska besvaras: 1) vilket övergripande perspektiv lyfts fram i de olika prispresentationerna, 2) går det att identifiera några

Inom komplex analys och operatorteori studerar man vanligtvis begränsade linjära operatorer mellan Banachrum bestående av analytiska funktioner. Detta görs för att kunna erhålla information om själva Banachrummets struktur. Ett klassiskt exempel är Cesaros medelvärdes operator på H^p , ett Hardyrum bestående av analytiska funktioner. En generalisering av denna operator är det så kallade Cesaros Inspired by the study of generalized Cesaro operator T_g introduced by Aleman and Siskakis we study a variation of this operator,namely P(g,a) , depending on an analytic symbol g and an n - tuple of complex numbers, a . Regarding the boundedness properties of this operator we prove that P(g,a) is a bounded linear operator from H^p to itself if and only if g is an analytic function of bounded mean

Graduation has been imposed in unilateral preferential trade agreements when product groups from beneficiaries or beneficiaries themselves are viewed as too competitive and developed. What happens to the product groups of the beneficiaries when the trade preferences are withdrawn? This paper addresses the potential trade effects of graduation from the European Unions Generalized System of Prefere

Given the HIV/AIDS peak in the 1980s, Uganda has been hailed as a success story after having dramatically decreased the infection rate in the 2000s. However, the country’s HIV/AIDS rate has started to increase again in recent years. At the same time, homosexual males represent a key population whose needs must be taken into account if the pandemic is to be eradicated. Therefore, the thesis focuses
