Volunteer tourism is an alternative form of tourism that is constantly increasing. The increase can be considered related to trends about social participation, environmental awareness and moral demands. Volunteering in developing countries has previously been associated with altruism and social responsibility, but more recently volunteer organizations have used personal development as part of thei

Wheel of Fortune or Academy of Vice? : Economic Ideals and Threats in the Swedish Lottery Debate, 1809–1840. This master’s thesis examines how ideas pertaining to economic and moral behaviour, ideals and threats were expressed, shaped and understood in the public debate about the state lottery – kungliga nummerlotteriet – in Sweden during early nineteenth century. At the time, state lotteries wer

Streptococcus pyogenes is a host-adapted human pathogen responsible for causing various infectious diseases, including rheumatic heart disease and acute rheumatic fever, some of which can be fatal to humans. The bacteria contain different pathogenic proteins situated on the cell surface or secreted extracellularly. Many of these proteins have the ability to bind to and activate human plasminogen.

Sverige och Tyskland skiljer sig i nivå av jämställdhet som råder i länderna. Det finns få vetenskapliga undersökningar hur förändringar i jämställdhet i ett samhälle manifesterar sig i heterosexuell dejting, särskilt i förändringar av användning av dejtingskript. Denna brist finns särskilt i Sverige och Tyskland. Syftet med denna uppsats är att analysera och jämföra användning av det klassiska de

Detta är en studie och jämförelse av speltekniska förutsättningar på Boehmflöjt, alt-, bas- och kontrabasflöjt. Utgångspunkten ligger i tekniska aspekter som fingerteknik, embouchure, artikulation och luftförbrukning. Även en jämförelse av nya speltekniker och hur dessa svarar på respektive flöjt förekommer. Undersökningarna har genomförts med stöd av erkänd flöjtlitteratur, praktisk övning samt sThis is a study of technical conditions and a comparison of the Boehm flute, alto-, bass-, and contrabass flute. The study involves technical aspects such as fingering, embouchure, articulation, and air consumption. In addition, there is a comparison of how commonly used extended techniques respond on the different flutes. The surveys of this thesis have been conducted through studying well-known

Objectives: This project aims to develop a deep learning-based attention decoding system that can distinguish between noise and speech in noise and also identify the direction of attended speech from the brain data recorded with electroencephalography (EEG) instruments. Two deep convolutional neural network (DCNN) models will be designed: (1) one DCNN model capable of classifying incoming segments

In this thesis, the subject of data-driven control of Unmanned Surface Vehicles (USVs) is explored. The control task is formulated through Nonlinear Model Predictive Path Following Control (NMPFC). System identification (SYSID) and Reinforcement Learning (RL) are employed to improve performance in a data-driven manner. The objectives were to assess the resulting controller’s path-following ability

Gängkriminaliteten är ett omtalat ämne som det kontinuerligt har forskats om. Forskningen har utvecklat kunskap gällande varför individer blir gängkriminella och vilka faktorer som gör att gängkriminella är kvar i gänget. Däremot finns det mindre forskning om vilka insatser som är effektiva för att lämna gänget och varför. Den aktuella studien syftade till att sammanställa den internationella forsGang criminality is a much-discussed topic that is extensively researched. The knowledge gained from the research explains why individuals become gang criminals and which factors make gang criminals remain in the gang. However, there is less research on which interventions are effective for leaving the gang and why. The current study aimed to compile the international research literature on the in

This study investigates xenoliths present in various dykes on Tenerife, the Canary Islands. These xenoliths were studied by means of fieldwork, petrographic analysis, scanning electron microscopy, laser fluorination, and LA-ICP-MS. In conjunction these analyses enable the understanding of the magmatic structures beneath the Anaga massif, with a conceptualisation of the formation of this volcanic s

This thesis studies the possibility of estimating the ambient temperature around a mobile phone using its internal temperature sensors. The thesis aims to develop and evaluate ambient temperature models that use internal temperature sensors within the device and, from a manufacturer’s perspective, investigate if the models for ambient temperature can be enhanced by tailoring them to the internals

Treatment planning plays a vital role in providing good treatment to cancer patients. In order to reach an adequate treatment plan, the algorithm used for simulating the dose in the patient must model the reality well. The most accurate algorithm for this is the Monte Carlo method, which in the context of radiotherapy treatment most often is used for pre-computing spot doses and optimizing the int

Denna studie undersöker möjligheterna att öka användningen av data inom fysisk handel och syftar till att förstå hur beslutsfattare kan generera värde från besöksräknarteknologi. Genom en kvantitativ forskningsansats undersöker studien potentialen hos moderna teknologier inom handelssektorn och introducerar Data Acceptance Model (DAM) som en teoretisk modell för att förstå acceptansen av data. Res

At its core, language is multimodal (Kendon, 1986; McNeill, 1994), and information presented through different channels of information, such as visually, in the shape of gestures, or verbally, in the shape of speech or signs, together facilitate online language processing (Kelly, Healey, Özyürek, & Holler, 2015; Kelly, Özyürek, & Maris, 2010). This thesis extends previous studies on multim

Does economic globalization impact sexual beliefs, contributing to the rise of right-wing parties? Although voters may not discern threats from trade shocks, individual economic insecurity theoretically impacts cultural attitudes and sparks a backlash towards outgroups, in turn contributing to right-wing candidates that campaign leveraging intolerance. Considering that scholars provide evidence fo

In the past decade, micro-enterprise development has gained popularity as an intervention in the Global South, including Colombia, a country where more than 90% of businesses are micro. For decades, this country has endured an internal conflict that has left millions of victims of forced displacement, who live in vulnerable situations and, in many cases, resort to creating micro-enterprises to mak

Despite prayer being one of the most central tenets of Islam, this subject has drawn the attention of surprisingly little scholarship, especially when it comes to studying its origin against pre-Islamic analogues. Thus, this thesis proposes a reconstruction of the very early history of the fivefold daily Islamic liturgy, attempting also to weigh the extent of the influence that pre-Islamic religio

The purpose of this paper is to speak on the similarities and differences between the Traverso and the Boehm-flute, specifically on interpretation and focusing on the embouchure, sound colour, and tuning systems. The written format of this study allowed me to express better and be more specific on the information selected to be more concise and beneficial to what I intended from this research. As

This thesis focuses on the development of financialisation and financialisation of everyday life in Sweden during the 1980s and 1990s. These years were turbulent for the Swedish economy and contains the so called turn to the market. This thesis uses the reports of NIER to analyse and describe the financialisation of everyday life and the genera l financial history of Sweden at the time. The NIER r

Denna studie syftar till att undersöka sambandet mellan hög mobiltelefonanvändning och allmänt mående bland gymnasieelever. Med stöd från två välgrundade teorier: självregleringsteorin och sociala inlärningsteorin, har studien presenterat intressanta korrelationer och samband kring mobilanvändning och allmänt mående. Studien är uppdelad i två olika studier, en kvantitativ och en kvalitativ. KvantiThis study aims to investigate the relationship between high mobile phone use and general well being among high school students. With support from two well-founded theories: the self-regulation theory and the social learning theory, the study has presented interesting correlations and connections around mobile phone use and general ill-health. The study is divided into two studies, one quantitativ
