Although they lead to several potential sustainability benefits, product-service systems are not intrinsically sustainable. Therefore, this thesis investigates the factors designers should consider in order to ensure sustainable results. A systematic literature review on product-service system and sustainability is combined with three interviews with product-service system providers. The results are analysed through the application of the Framework for Strategic Sustainable Development. The results of the systematic literature review show that there is no unified definition of sustainable product-service system and multiple approaches to address sustainability in product-service system design. By adopting the Framework for Strategic Sustainable Development, a definition of sustainable product-service system and a list of design criteria are developed. This thesis suggests which overarching aspects product-service system designers should consider to integrate a strategic sustainability perspective. The outcome of this thesis supports designers in understanding what a sustainable product-service system could be and what elements it should embed. By combining the definition and the list of criteria, designers can apply a systematic and strategic approach to integrate sustainability in product-service system offerings.

Existe a necessidade de modificar o processo de projeto diante da crescente complexidade envolvida em empreendimentos da construção. Há envolvimento de muitos profissionais, existência de distintas metas e interesses, além da ampliação do escopo dos projetos desenvolvidos. Além disso, o processo tradicional de projeto é geralmente desenvolvido de forma fragmentada, desconsiderando o conhecimento de vários estudos acadêmicos já desenvolvidos, sendo as decisões tomadas geralmente com base na experiência dos projetistas. Nesse sentido, uma das abordagens que vem sendo usada para melhorar os projetos de edificações é o projeto baseado em evidências (Evidence-Based Design - EBD). EBD é um processo que visa a melhorar as decisões de projeto tendo como base o uso das melhores evidências disponíveis de pesquisa, aliadas à prática profissional e a dados relacionados aos requisitos do cliente. O presente trabalho teve como objetivo desenvolver um modelo conceitual para guiar o uso do EBD no processo de projeto de edificações. A pesquisa foi dividida em três estágios. O primeiro estágio, de caráter exploratório, buscou a compreensão da pesquisadora quanto ao tópico investigado (EBD). No segundo estágio, buscou-se entender a aplicação do EBD no processo de projeto com enfoque na geração de valor Já o terceiro estágio buscou desenvolver formas de disseminação de resultados baseados em evidência. Ao longo dos três estágios, foram realizadas três revisões sistemáticas de literatura e também três estudos empíricos, sendo dois desenvolvidos no contexto de habitação de baixa renda no Brasil, enquanto que o terceiro foi realizado em um empreendimento da área da saúde no Reino Unido. O estudo apresenta tanto contribuições práticas como teóricas. Sob um enfoque prático, a principal contribuição é a possibilidade de integração de evidências existentes no processo de projeto a partir do desenvolvimento de algumas formas de coleta, processamento e análise dessas evidências. Em termos teóricos, este estudo propõe uma nova abordagem conceitual sobre nomenclatura e classificação de evidências para o processo de projeto usando EBD, com foco na geração de valor. É apresentada uma proposta de processo de projeto que busca uma melhor integração entre a prática profissional com conhecimentos produzidos pela academia, por meio de um processo de geração de conhecimento como uma forma de aprendizagem contínua. / There is a need for changing the design process due to the growing complexity of construction projects. There is a large number of stakeholders, which have a diversity of aims and goals, in addition to the broader scope of building projects. Moreover, the traditional design process is usually developed in a fragmented way, based mostly on the designers’ experience, often disregarding knowledge from other stakeholders involved. Evidence based design (EBD) is an emerging approach that aims to address this problem by supporting project decision-making with available evidence from research, in addition to professional experience and clients requirements’ data. This research work has proposed a conceptual model to guide the use of EBD in the building design process. The study was divided into three stages. The first stage had an exploratory character, in which the focus of the researcher was on understanding EBD. In the second stage, the aim was to study the application of EBD in the design process, focusing on value generation. The third stage consisted of devising forms of disseminating evidence-based results Three systematic literature reviews and three empirical studies were developed along those three stages. Two studies were concerned with affordable housing projects in Brazil, and one study involved a care home project in the U.K. This work provides both practical and theoretical contributions. From a practical viewpoint, the model proposed herein integrates evidences in building design process and proposes techniques to collect, process, and analyse such evidences. From a theoretical viewpoint, it introduces a new terminology and classification for evidences that can be incorporated in buildings design by using EBD, for increasing value generation. A proposal for a new design process that improves the integration between the professional practice and knowledge produced by academics, through a process for generating knowledge as a form of continuous learning.

This thesis provides a systematic literature review of a selection among current papers andarticles on Green Information Systems (IS). The main focus is on the current state of Green ISin academic research. This study aims at gaining a deeper understanding and a clearer view ofthe state-of-the-art of IS for environmental sustainability research, with the goal of clarifyingthe diffuse idea of what Green IT/IS is, and what differentiates Green IS from Green IT.To support the objective of this study, the articles selected for data analysis were collected byusing a systematic literature review as research and analytical method. Within the thesis, adescriptive angle with an interpretative character is used to analyse the data extracted.A theoretical framework based on concepts from sustainability, Green IS and Green IT isemployed in order to analyse and compare terminologies and frameworks used in the studiedarticles. Furthermore, the different dimensions of sustainability and the various terms used todescribe Green IS are analysed comparatively.The result and analysis are discussed in a conclusion confirming the on-going ambiguity ofthe terms Green IT and Green IS and the transformative power of IS. This study aims tocontribute to our understanding of some of the existing problems that hinder further researchin the context of Green IS. Finally, we emphasise the importance of clear definitions in orderto advance the IS position for transforming society in a sustainable direction. / Program: Systemvetarutbildningen

Correct functioning is the most important requirement for any system. Nowadays there are a lot of threats to computer systems that undermine confidence in them and, as a result, force a user to abandon their use. Hence, a system cannot be trusted if there is no proper security provided. Firewalls are an essential component of network security and there is an obvious need for their use. The level of security provided by a firewall depends on how well it is configured. Thus, to ensure the proper level of network security, it is necessary to have properly configured firewalls. However, setting up the firewall correctly is a very challenging task. These configuration files might be hard to understand even for system administrators. This is due to the fact that these configuration files have a certain structure: the higher the position of a rule in the rule set, the higher priority it has. Challenging problems arise when a new rule is being added to the set, and a proper position, where to place it, needs to be found. Misconfiguration might sooner or later be made and that will lead to an inappropriate system's security. This brings us to the usability problem associated with the configuration of firewalls. The overall aim of this thesis is to identify existing firewall usability gaps and to mitigate them. To achieve the first part of the objective, we conducted a series of interviews with system administrators. In the interviews, system administrators were asked about the problems they face when dealing with firewalls. After having ascertained that the usability problems exist, we turned to literature to get an understanding on the state-of-the-art of the field and therefore conducted a systematic literature review. This review presents a classification of available solutions and identifies open challenges in this area. To achieve the second part of the objective, we started working on one identified challenge. A set of usability metrics was proposed and mathematically formalized. A strong correlation between our metrics and how system administrators describe usability was identified. / Network security is an important aspect that must be taken into account.

This dissertation presents three separate studies designed to investigate the relationship between marriage and physical activity behavior. First, a systematic literature review of nineteen articles presents qualitative and quantitative articles from 2000 to 2010 that focus on the relationship between marriage and physical activity and/or exercise. Based on the findings from the review, social support (or lack of support), culturally-determined gender roles, environmental factors such as income level, and intrapersonal factors such as self-efficacy each influenced spousal physical activity. Secondly, a qualitative study based on interviews and photographs from twenty-four married individuals utilized Social Cognitive Theory to explore the mechanisms, determinants, and influences of spousal physical activity. Findings indicate verbal persuasion by husbands encouraged wives, yet verbal persuasion by wives was perceived as nagging by men. While verbal persuasion by husbands increased a small number of wives' sense of self-efficacy, the majority of women felt that persuasion increased motivation, not necessarily confidence. Findings also highlighted the power of modeling to increase husbands' physical activity. Overwhelmingly, men reacted more positively to modeling than verbal persuasion. Lastly, a second qualitative piece employed General Systems Theory to conceive of the marital unit as a type of system working within other broader systems. Findings highlighted the desire for increased quality time as a motivator for physical activity within the marital system. Also, the larger cultural, occupational, and familial systems greatly influenced marital dyads. Cultural expectations to be the primary caregiver negatively impacted wives while occupational pressures negatively influenced both parts of the marital dyad. Regarding the familial system, parents cited the influence of their own parents as well as a desire to "pass on" exemplary physical activity habits to their children. Finally, couples with children highlighted an increase in exercise frequency yet decrease in exercise intensity.

This study investigates the literature of the Creative Pedagogy of Play to examine the potential for this pedagogy to support cultural identity development of immigrant preschoolers in the Swedish context. Twelve articles were reviewed in order to characterize outcomes of the Creative Pedagogy of Play potentially relevant for this support. Identified outcomes included: recognizing and promoting children’s agency, co-creation of an imaginary world through diverse forms of expression, emotional involvement (“perezhivanie” as lived through experience), building peer relationships, valuing ambivalence, narrative teaching and narrative learning.  In this thesis, we argue that these outcomes of Creative Pedagogy of Play have the potential to create supportive conditions associated with the development of cultural identity (such as: social inclusion, respect for diversity, care, guidance and teaching offered by adults, recognizing children’s agency, and building relationships with friends and peers). The combination of these conditions creates a potential for the cultural identity formation through the Pedagogy of Play. Implications of this systematic review for early childhood education research and practice are discussed with particular focus on implications for engaging with questions of culture in preschool pedagogy.

Children with intellectual disabilities (ID) in inclusive classrooms differ in ways of processing information and learning speed compared to their peers without disabilities. Therefore teaching methods must be adapted to their individual needs. Peer support is seen as an additional form of improving students’ academic engagement. This systematic review focuses on peer supported interventions which facilitate academic engagement of children and youth with mild to profound ID. It contains six studies, which met pre-determined inclusion criteria focusing specifically on academic engagement. The studies were analysed to examine (a) different types of peer support, (b) peer support characteristics, (c) definition of academic engagement of students with ID and (d) if a change in academic engagement as an outcome can be evaluated after a peer support intervention. In this review, the data of 18 students with mild to profound ID and their peers in the age of 8 to 17 years, were included. Four different types of peer support intervention were identified, which included different characteristics mostly focussing on supporting students’ communication, access to information and active participation in class. The different definitions of academic engagement which were found hindered comparison of results. Nevertheless, all studies had a positive effect on the academic engagement of students with ID. Future research is needed to investigate the long-term impact of different types of peer support on academic engagement of students with ID and their need in relation to specific forms of ID.
