Denna studie har ämnat att undersöka den potentiella skillnaden mellan tjejers och killars narkotikabruk i årskurs 3 på gymnasiet, i Södra Sverige. Det är av intresse att undersöka potentiella könsskillnader, då behovet av olika typer stöd och insatser kan tänkas skilja sig åt mellan tjejer och killar. En kvantitativ metod i form av en enkätundersökning har använts för att uppfylla studiens syfte.

Fabriksrevision används som ett verktyg för att kontrollera att leverantörer och underleverantörer uppfyller kraven i kontraktsvillkor och det är ett steg i uppföljningsprocessen. I decennier har det rapporterats om arbetsrättsliga- och människorättsliga kränkningar i globala leveranskedjor där fabriksrevision används som en mekanism för att säkerställa goda arbetsvillkor. Dock kritiseras fabriksrSocial audits are used as a tool for performing reviews on suppliers’ and sub-suppliers’ compliance towards contractual obligations and is a step in the review process. There have been reports of violation of labor- and human rights laws in the global supply chains where social audits are put in place to secure good working conditions. Business segments have been criticized to have failed on their

Wellbefy is a company that offers its customers a digital platform with the goal to increase wellbeing at workplaces. Through their platform and their users, they are obtaining data connected to areas in which problems often occur, such as sleep or stress. The platform can be used by anyone working at a company, from the boss to an employee. The problem with the current platform is that it can on

In the last few decades, the population in Lithuania has been gradually becoming older due to a combination of the declining fertility rate, negative net migration, and rising life expectancy. It is estimated that this process will be even more rapid in the future, as it is projected that by the year 2100 the share of elderly people over 65 will increase by 84%, whilst the working-age population (

This paper proposes and investigates a Bayesian relation between optimal L2 regularization strengths and the number of training patterns and hidden nodes used for an artificial neural network. The results support the proposed dependence for number of training patterns, while the dependence on hidden architecture was less clear. Finally, applying different regularization strengths on different laye

Den digitala omställningen har ökat genom åren och har fungerat till en fördel för företag och organisationer generellt. Hastigheten på transformationstillväxten har bibehållits i nutid, vilket har resulterat i att mjukvarusystem utvecklas kontinuerligt. Som en naturlig effekt av detta fenomen, bör aktuella företag alltid ligga i framkant för att förbli konkurrenskraftiga. Studier har visat att pr

The problem of pricing American stock options is far more complex than pricing European options due to the possibility of early execution. This feature means that the decision to either hold on to the option or exercising it early must be continually evaluated, leading to closed form solutions such as the Black-Scholes Formula to not be applicable on American options written on dividend paying ass

IKEA, a company well known around the world for their furniture, is also keen on using digital solutions to improve the customer experience. One of these solutions is the self-serving kiosk, a 27" touchscreen, that helps the customers find and buy products. As many other companies of similar size, IKEA wants to use the data from their digital solutions, as a base for some of their decision ma

This thesis presents the first attempt to estimate Dissolved Organic Carbon (DOC) in inland waters over a large-scale area using satellite data and machine learning (ML) methods. Four ML approaches, namely Random Forest Regression (RFR), Support Vector Regression (SVR), Gaussian Process Regression (GPR), and a Multilayer Backpropagation Neural Network (MBPNN) were tested to retrieve DOC using a fi

Med ökande koncentrationer av koldioxid (CO2) i atmosfären kan energieffektiva tekniker för koldioxidinfångning (CCS) bli viktiga för att växthusgasutsläppen ska minska. Rapportens syfte har varit att experimentellt bestämma och utvärdera fyra egenskaper hos lösningar av vatten, dimetylsulfoxid (DMSO) och aminoalkoholen 2-amino-2-metyl-1-propanol (AMP) som ska användas i en pilotanläggning. Vid inWith increasing atmospheric carbon dioxide (CO2) concentrations, energy efficient carbon capture and storage (CCS) technologies could prove important to enable reductions in the global CO2 emissions. The aim was to investigate a novel, non-aqueous, and precipitating chemical absorption system of dimethyl sulfoxide (DMSO) and 2-amino-2-methyl-1-propanol (AMP), which forms solid carbamate salt cryst

Den europeiska granbarkborren är en insekt som för många räknas till skadedjur. Den har varit ansvarig för förstörelse av över 150 miljoner m3 granskog i Europa under de senaste 50 åren. Global uppvärmning har orsakat förändringar av barkborrens utbredning då problem uppstått med stora utbrott som nu regelbundet inträffar i norra Europa på grund av varmare och utdragna sommarsäsonger. Sverige har The European spruce bark beetle is an insect that is often referred to as a pest. Responsible for the destruction of over 150 million m3 of Norwegian spruce forest in Europe over the last 50 years makes this insect one of the major disturbances to the forest industry. With global warming at large, changes of the distribution of the bark beetle have emerged with large outbreaks now regularly occurr

Personalization is a strategic way for retailers to tailor an experience based on information provided by the customer, to fulfill the individual's needs. It has been explored in great detail, resulting in benefits being revealed, as well as strategies being put forth. However, this study identifies great possibilities to improve our knowledge of the research field, by adopting a holistic appr

This study explored what consumers value about Influencer Launched Brands, utilising the novel concept of Human Brand Publics as a theoretical foundation to analyse this phenomenon. Simultaneously, this research aimed to develop the novel theoretical contribution of Human Brand Publics. Qualitative data from Generation Z, Influencer Launched Brands consumers was gathered and analysed to develop a

Since a brain injury often can affect the memory in some ways it is sometimes hard to remember to bring that piece of paper. And since more and more people of the aging population carry a cellphone daily - the need for a digital alternative to My health document became more apparent. In this project we got the task of digitalizing My health document. We confirmed the need for a digital solution by

Syftet med denna uppsats har varit att genom en litteraturstudie av två vetenskapliga artiklar som undersökt medierapporteringen kring två fall rörande protester i sportsliga sammanhang, försöka ta reda på hur medierapporteringen i amerikanska tidningar sett ut för respektive fall och jämföra dessa med varandra för att hitta likheter och olikheter. Fallen det rör sig om är Tommie Smith och Joh

I have always been curious about the effects architecture and the built environment have on us. The special atmosphere and the ability to arouse a sense of safety and calmness, but also the negative feelings certain spaces can evoke. Which architectural elements contribute to the way we perceive a space and more importantly, does the built environment not only affect our emotions but also our ment

The purpose of this study is twofold. The first is to examine the board monitoring's impact on accrual-based earnings management, as reflected by the absolute value of discretionary accruals. The second is to investigate the moderating effect of CEO power on the relationship between board monitoring and accrual-based earnings management. The study follows a deductive approach and a quantitati

The purpose of this paper is to investigate one of the seven characteristics proposed by Northcott and Alkaraan (2007): the characteristic of non-programmability. This paper responds to the call for a nuanced understanding of how companies are programming strategic investment decisions (Alkaraan, 2016, p. 520). The purpose is fulfilled by conducting multiple case studies. The data collection metho
