In this work we investigate the spin correlation effect of the interference between signal and irreducible background events present in top quark pair production at the LHC at LO in the dilepton channel. To simulate the high energy proton-proton collisions of the LHC, MadGraph5_aMC@NLO framework is used as an event generator. The spin correlations are explicitly measured via the lepton kinematics

Work-related threats and violence is a common problem that many social workers have to handle frequently. The definition of this phenomenon is ambiguous and social secretaries have to learn how to handle these types of situations. This bachelor thesis will focus on how they perceive this and how they cope with it, as well as the consequences of their perceptions and coping strategies. To answer th

This thesis aims to critically investigate how a service organization’s physical spaces, particularly the toilet areas, impact LGBTQ+ individuals’ well-being. More particularly, this research focuses on Lund University in Sweden, a service organization with significant international and societal influence. As service organizations face pressures to become more socially and environmentally sustaina

Title: Development of a Forecasting Model for Original Equipment Manufacturer (OEM) Components. A Design Science Study at Tetra Pak. Authors: Faruk Kodzaga & Giacomo Daniele Supervisor: Jan Olhager, Department of Industrial Management and Logistics Background: The importance of accurate demand forecast is set due to the drivers of short lead-times, just-in-time-deliveries and cost effective

Ur ett demokratiskt perspektiv är muntlig framställning viktigt eftersom förmågan att göra sin röst hörd är såväl en rättighet som en skyldighet i ett demokratiskt samhälle. Dessutom är muntlig framställning ett krav för att elever i gymnasiet ska bli godkända i svenska. Att talrädsla är vanligt förekommande bland gymnasielever är således problematiskt. Syftet med denna studie var att undersöka läTranslated title: “Many students find it difficult even if they do not suffer from speech anxiety”: An interview study on teachers’ perspectives on upper secondary school students’ speech anxiety and on oral presentations in relation to the democratic mission From a democratic perspective, oral proficiency is important since the ability to make one’s voice heard is a right as well as a responsibi

The main goal of the Paris agreement is to hold global warming below 2 degrees Celsius. A goal which requires a rapid peak and decline of global emissions. With the adoption of the Paris agreement, countries submitted Nationally Determined Contributions making national climate legislation a key tool for how to reach the goal. While the response so far has failed to reduce global emissions, climate

A growing population with increasing life expectancy means that the proportion of cognitively ill people is increasing. This puts pressure on the home care service due to lack of time and resources, which leads to a decline in the well-being and quality of life of care recipients. A consequence of cognitive illness is memory loss, which leads to everyday chores such as toothbrushing often being fo

Psykiska besvär är vanliga hos barn och ungdomar och gör det svårare att fungera i vardagen. Tidigare forskning visar flera samband mellan olika typer av psykiska besvär (symptomdimensioner) och funktionsområden (exempelvis skola, socialt), men det finns få studier som har undersökt flera symptomdimensioner och flera funktionsområden samtidigt. Den här uppsatsen undersökte samband mellan tre symptMental health problems are prevalent and impairing in childhood and adolescence. Earlier research shows multiple links between different mental health symptom dimensions and different areas of everyday functioning (e.g., school, friends), but there is a dearth of studies investigating multiple symptoms dimensions and multiple areas of functioning at the same time. This thesis investigated links be

The aim of this study was to understand social workers' descriptions about factors that affect and prevent young men from committing a delinquent act. The study was based on semi-structured interviews with six social workers from different organizations in Sweden that worked with young men involved in juvenile delinquency. We analyzed the descriptions with Travis Hirschi's social control t

Under Covid-19 pandemin bromsades hela världsekonomin, arbetslösheten ökade både i Sverige men även i den resterande världen. För att stimulera ekonomin använder sig ett flertal länder av ett program som heter kvantitativa lättnader för att stimulerar ekonomin. Det är därför centralt att undersöka om de är kvantitativa lättnader som ledde till de accelererade aktiemarknaderna under Covid-19 pande

The aim of this study is to analyze how professionals in swedish substance abuse care relate to gender and sexuality in their work. The aim was furthermore to explore how they experience their competence regarding these issues as well as how it affects their treatment and work. The empirical material consists of six semi-structured interviews with professionals of health and rehabilitation clinics

Swedish social workers are generalists and on the broad field of work are often employed with different titles. The profession of social workers is therefore considerably difficult to define. What does this mean for the social workers’ professional identity at large? The aim of this study was to give account to how newly graduated social workers experience and reason about their professional ident

The purpose of this thesis is to examine if Swedish sustainable funds, which invest in Swedish companies and are registered in Sweden, have a higher risk-adjusted return than Swedish traditional funds. The main purpose is to evaluate the risk-adjusted return during the pandemic Covid-19 and the ongoing Russia-Ukraine war. We construct two different portfolios; one sustainable and one traditional p

Foreign aid with the aim to promote gender inequality within low-development countries (LDC´s) has increased significantly during the last decade. According to a report published by the OECD, bilateral assistance from the OECD Assistance Committee (DAC) aimed at increasing gender equality reached an average of 44.8 billion US dollar during the period 2016-2017. OECD, together with the World Bank,

Jus cogens norms and obligations erga omnes are concepts within international law that are often used to reinforce legal claims. This thesis aims to assess to what extent invoking these concepts, along with their reinforcing capabilities, is justified in specific cases. In order to achieve this, the thesis first gives an overview of the theoretical debate surrounding the concepts of jus cogens no

The EU is establishing its leadership in setting global rules and standards for sustainable development over the world through legal instruments with transformational effects on third countries. On the one hand, the EU is the leading region in the development of mHRDD legislations which has been hardened for the last decades and is now evolving to become CSDD, generating extraterritorial effects f

To meet the growing demand of meat alternatives, this project was dedicated to creating a chicken analogue prototype with mycoprotein. Within the project, two approaches of alginate gelation, external (diffusion) crosslinking and internal crosslinking, were studied in this particular food matrix. Using the external crosslinking method, the effects of major ingredients on the texture, structure and

Food scarcity is a common occurrence for farmers in the rural Himalayan regions. As fruits and vegetables are a crucial part of most farmers' diet, food deficiency can become evident in between harvesting periods, when there is no fresh supply. A lack of proper storage facilities and preservation methods further amplify this as the commodities that are stored can start to rot. The farmers do t

This thesis aims to explore how managers comprehend the systemic value of a companies’ Performance Management System (PMS). The study findings show that PMS causes path-dependent behavior, leading to organizational rigidities, strategic inertia, and diminishing PMS effectiveness. Managers' comprehension of the multifaceted, complex, and systemic nature of PMS can counteract the unintended nega
