Efficient variability management is a key issue in large-scale product line engineering, where products with different propositions are built on a common platform. Variability management implies challenges both on requirements engineering and configuration management. This paper presents findings from an improvement effort in an industrial case study including the following contributions: problem
When developing products, engineering designers often face the problem that their candidate for a technical solution, ranging from a concept to a detailed design, needs to be analyzed by a design analyst before it is approved or rejected and the engineering designer can continue his/her activities within the product development process. If engineering designers have to send every solution candidat
By the end of the 1960s there was a growing environmental concern all around the globe. As a part of an answer to this challenge the need was recognized for a reorientation of the education processes towards developing knowledge, attitudes and skills for resolving the issues. This was the birth of the concept of Environmental Education (EE). However, this notion is far from being static as it went
Purpose of study: As both innovations and brand loyalty are becoming ever more important for companies today, it is of importance to understand how an organisation can handle the relationship between the explorative and exploitative units when working with these two constructs. The ultimate aim is to understand how service organisations can be managed in order to enhance brand loyalty through serv
Positive aspects of fathers’ involvement in parenting are broadly recognized, but challenges faced by fathers are often neglected and postpartum depression (PPD) is still mainly considered as a problem of mothers. Yet, new evidence suggests a similar prevalence of about 10 % in fathers and mothers. The present study investigated paternal PPD, its character and its links to attachment styles, paren
The aim of this research is to study three particle correlations in pseudo-rapidity for the $\Lambda^0$,$\Xi^0$, and $\Omega^-$ hyperons with a focus on their baryon and strangeness quantum numbers. The two primary questions asked are, into which particles are these quantum numbers typically conserved, and what are their correlations in momentum space. The research investigates these problems by e
This thesis project explores the significance of public spaces in shaping society, culture, and individual identity, emphasizing their role in promoting democratic values and self-realization. Public spaces, such as squares and marketplaces, serve as platforms for social interaction, economic activity, and cultural continuity. The design of these spaces reflects societal values and historical cont
There is a need to closer characterise the molecular changes associated with progression from low to high mortality stage cutaneous T cell lymphoma. This has been challenging since there is high inter-patient heterogeneity in the genetics and transcriptomics of the malignant T cell populations. Modern technology has enabled single-cell resolution as well as spatially guided cell selection for whol
The upcoming implementation of the ReFuelEU Aviation Initiative presents both challenges and opportunities for the European aviation sector. Starting January 2025, the EU’s aviation fuel mix must include at least 2% Sustainable Aviation Fuel (SAF), leading to higher operating costs for airlines due to SAF’s higher price than fossil kerosene. Additionally, the entire fuel supply chain will need to
Böcker och läsning är ett centralt motiv i berättelsen om Jane Eyre (1847), vilket på många sätt bidrar till framställningen av karaktärisering, världsbygge och narrativets framfart. Det finns särskilt samband mellan framställningen av böcker och läsning och framställningen av makt och maktdynamiker i Jane Eyre. Tidigare forskning om böcker och läsepraktiker i Jane Eyre har fokuserat på den allusiBooks and reading are a central motif within the narrative of Jane Eyre (1847) by Charlotte Brontë and contributes in many ways to the depiction of characterisation, world-building, and the progression of the narrative. In particular, there are correlations between the depiction of books and reading and the depiction of power and power dynamics in Jane Eyre. Previous research into books and readin
Major depressive disorder (MDD) is a prevalent psychiatric condition and poses a significant burden on public health. The underlying causes and mechanisms of depression remain poorly understood. There is a growing body of evidence linking microRNAs (miRNAs) to major depressive disorder (MDD). However, the causal relationship between miRNAs and MDD remains unclear. This study aimed to investigate t
The Iberian Lynx (Lynx pardinus) faces imminent endangerment due to climate change resulting in the declining population of its primary prey, the European Rabbit (Oryctolagus cuniculus). With ongoing environmental shifts, this threat intensifies, heightening the risk of extinction for the species. The aim of this study was to explore a potential conservation strategy; the possibility of relocating
Purpose: The purpose of this study is to investigate the impact of sustainable packaging for cosmetics on consumers within Europe. Methodology: Literature Review, Case Studies, Online Survey Findings: The research conducted exemplifies that sustainable packaging of cosmetic products impacts European consumers’ perception of brand image and influences purchasing decisions. Four key factors from the
Tropical rainforests cover large parts of the Democratic Republic of Congo. In light of recent surges in deforestation in the country, protected areas are a decisive component of the national conservation strategy. Intended to preserve ecosystems, the way in which these areas are organized can have vital implications for people who reside within them through the changes they cause to environmental
Traditionell biologisk näringsavskiljning inom avloppsvattenrening, såsom denitrifikation och biologisk fosforavskiljning (EBPR), kräver tillgång på lättnedbrytbart kol för att bra reningsgrad ska uppnås. Dock är en stor andel av kolet i det inkommande avloppsvattnet partikulärt och måste hydrolyseras innan det blir tillgängligt för bakterierna i den biologiska reningen. Flera studier har studeratTraditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. Several studies have investigated the possibility to produce an internal carbon source from the g
The aim of the project was to develop a methodology for the chromatographic analysis able to identify the key odorants in meaty food products. The approach was based on the analysis of an already in market product and the theoretical background of the meaty flavors sensorially. Firstly, a custom-made flavor was created for the experiments covering as much as possible a broad area of compounds prec
The axiom of transitivity states that if a person prefers option A to B and B to C, he must also prefer A to C. This simple axiom is often seen as one of the pillars of rational choice, but whether it should be has created a divide in the research community. Some state that there cannot be rational choice or utility without transitivity and that agents who present intransitive preferences allow th
This thesis explores how Employee-Driven Innovation (EDI) unfolds within Swedish municipal organizations and identifies how EDI is managed and structured, and what kind of innovations that are created in such organizational environments. While innovation is increasingly emphasized in the public sector, this study reveals that its practice is far from uniform. Through qualitative studies of three m
The purpose of this qualitative study is to explore how the Swedish community support organizations BUFFF and Solrosen support children and youths with incarcerated parents with a focus on how they address stigma, provide safe spaces, and help prevent intergenerational criminality. Through semi-structured interviews with professionals from both organizations, this thesis examines how these childre
