    Justifying the Unforgivable: how ideology shapes patterns of violence of Boko Haram and Al-Shabaab2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The question of how armed group ideology influences its behaviour has been tentatively explored in the past decade. However, which role distinct ideological commitments play in civilian targeting has not been satisfactorily discussed thus far. This thesis turns to research on genocide and mass violence and incorporates the concepts of ‘exclusionary ideologies’ and ‘threat perceptions’ to fill this research gap. It addresses the following question: to what extent do exclusionary ideologies of armed groups influence their use of violence against civilians during civil conflicts? When revolutionary armed groups pursue their goals, threat perceptions determine which groups are considered legitimate targets for attack. Therefore, it is hypothesized that exclusionary groups will employ more violence against civilians than inclusionary groups because the former have a more expanded understanding of legitimate targeting than the latter. Through a structured focused comparison, discourse analysis and process tracing applied to the cases of Boko Haram and Al-Shabaab, moderate support for this hypothesis is found. It is shown that both armed groups to varying extents invoke threat perceptions regarding certain out-groups to legitimize and rationalise their patterns of violence. Nonetheless, a descent into indiscriminate violence by Boko Haram and data shortage of Al-Shabaab attacks warrant caution.

    Expanding Mediation Theory: Gang Conflict and Mediation in El Salvador2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The field of mediation within peace and conflict studies has remained almost entirely focused on state-based armed conflicts and traditional non-state armed groups (NSAG). This restricts our ability to address other actors and emerging forms of conflict in non-conflict and post-conflict settings. This includes a certain classification of gangs who display strong similarities to typical NSAGs. This study analyses gang mediation and its effects on levels of violence in gang conflicts in El Salvador through the lens of traditional mediation theory from the field of peace and conflict studies. It seeks to answer the question, how does mediation influence levels of violence within gang conflicts? More specifically, addressing the hypotheses that, mediation between gangs, and government support for mediation, will likely lead to lower levels of violence. Using a qualitative comparative case study method, employing a structured, focused comparison between three different time periods in El Salvador, I find support for both hypotheses, showing that gang mediation leads to a significant reduction in violence albeit conditional on government support. In addition, factors such as dialogue, information sharing, leverage, concessions and the signing of an agreement are essential in the process between mediation and lower levels of violence.

    E-loyalty in digital platforms: How do the employees in banks experience their work with customer e-loyalty, individually and in relation to each other?2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to study how the top management and employees in banks experience their work with customer e-loyalty in digital settings, both individually and in relation to each other. Today's bank customers desire freedom in where they conduct their business and do at the same time require a deeper personal relationship with their bank advisors. The adjustments to balance these two requirements have been a challenge for many banks. While satisfied customers often create loyalty, banks in Sweden have during the recent years experienced decreasing customer satisfaction. The digitalization within the banking sector will continue to have a big impact on the relationship between banks and their customers. By adapting a qualitative approach, the thesis aims to contribute with knowledge of how the top management and employees work with and perceive the impact digitalization has on e-loyalty. The thesis provides academic contributions, such as the insight in how top management and employees in two of Sweden’s biggest banks perceive their work with customer e-loyalty. The second contribution to the literature is a suggestion to development of the 8C model. The practical contribution is what the top management in banks should consider when mediating e-loyalty strategies to employees

    En mellanchefs roll i ett förändringsarbete: En fallstudie om hur ett förändringsarbete påverkar en mellanchef2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Change is a timeless phenomenon that takes place in organizations daily. Research shows that middle managers are often perceived as opponents of organizational change. On the other hand, research also shows that their role is very important for implementing change. This qualitative study examines the potential challenges that may arise during the implementation of change. The study also aims to highlight the individual’s experience of the middle manager’s role during a change created by the upper line. Our choice of research methodology includes semi-structured interviews. The study consists of interviews of five middle managers in the Primary care of Region Gotland. The theoretical framework has been used as a guideline in the process of creating interview questions. The theory of the research study is constructed using theories about change management, change resistance, job satisfaction and the role of the middle manager. Our empirical data has been analyzed with selected theories. Our research indicates that the middle managers often end up in a conflict of roles. The most noticeable challenge for middle managers is the need to prioritize their roles. This often occurs due to a lack of resources.

    Minority Discount in Publicly Traded Firms2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This paper examines the minority discount due to lack of control by looking at tender offer premiums on Swedish publicly traded firms from 2007 to 2018. We analyze how ownership structure, the acquired stake and distribution of shares affect the minority discount. Variables focusing on control of shares are tested individually but also included in models addressing additional impacts. Our findings suggest that a bidder’s ownership of the target firm prior to the announcement lowers the bidder’s valuation of the remaining shares. However, the relation between premium and ownership seem to depend on a threshold of having a toehold which justifies the argument of toeholds attaining control and influence of the target firm. Correspondingly, the premium per share increases with the partial interest acquired, suggesting a non pro-rata valuation. We find no evidence of additional premium for minority shareholders in squeeze out events. However, equally powerful blockholders in target firms tend to increase bid premiums, arguably due to increased competition which aligns bid premium valuation to the valuation of control between dual class shares.

    Uppfattning av ledarskap: Skillnader och likheter mellan män och kvinnor i ledarpositioner2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today organizations need different strategies and models that can help them to lead and being led to success. Throughout the years there have been discussions about what leadership should be enforced within organizations to increase efficiency. People have different views about what an efficient leadership should look like and who it should be conducted by. Perceptions about who should lead has contributed to that men gained support in achieving leader positions, but has on the other hand led to difficulties for women to reach leader positions. Today it can be perceived strange and unfamiliar for both men and women to see a woman in a leading position.

    This study takes a qualitative approach. We have interviewed eight leaders in the security business and have thereby been able to apprehend which abilities, practice and style of leadership the study participants are applying in their leading.

    The analysis of the interviews has shown both similarities and differences in between the male and the female participants. We can also conclude that women face greater resistance in their leadership, while men don’t experience the resistance, which aggravates women to climb higher in leading positions.

    Leveraging Customer Information in New Service Development: An Exploratory Study Within the Telecom Industry2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    There is an increasing pressure on service firms to innovate and compete on new offerings. As our lives become more digitized through the ubiquitous connectivity by the usage of digital devices, companies are now able to collect vast amount of various data in real-time, and thus, know radically more about their customers. Companies could leverage on this growing body of data and developing relevant services based on customer demands accordingly. One industry compelled to benefit by utilizing customer information is the telecom industry due to fierce competition and a need of innovation in a saturated market. Hence, the purpose of this study is to investigate how telecom companies use customer information in their development process of new services by answering the research question: How do telecom companies use customer information within their New Service Development process? To illuminate this, a qualitative research was conducted on three Swedish telecom companies. The findings indicate that telecom companies possess a beneficial position since they are able to collect a vast amount of data about their customers due to the digital nature of their services. However, they struggle to efficiently integrate the data and seamlessly disseminate the obtained knowledge internally. Hence, leveraging customer information in new service development has not reached its full potential and how well it is incorporated is determined by the skills of key employees and their collaboration rather than deployed internal processes.

    The impact of strong ties, cooperation and realized absorptive capacity on new product innovativeness in the Swedish video game industry.2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The video game industry in Sweden has experienced tremendous growth since 2009 with its revenue generation being compared to iron ore, an important revenue generator for the country. The ability of these firms to record recurrent increases in revenue is due to the innovativeness of the industry. External sources of knowledge affect firms’ innovative performance. However, the complexity of the knowledge acquired is influenced by the strength of ties between the firm and its counterparts. This study investigates how Swedish video game firms develop new products to stay competitive through their relationship with their strong ties counterparts, level of cooperation and firms’ absorptive capacity. We model strong ties relationship with latent constructs including closeness, commitment and trust. A nationally representative survey was conducted among selected video game firms across Sweden. Structural equation modelling was then utilized to assess the effect of strong ties on new product innovativeness. The results show that strong ties with external counterparts have a positive and statistically significant effect on new product innovation through the mediating channel of cooperation and absorptive capacity. Closeness, commitment and trust show a direct effect on cooperation, cooperation on absorptive capacity and absorptive capacity on new product innovativeness. The implications of these findings have been discussed.

    Modeling the complex ejecta on 2017 September 6-9 with WSA-ENLIL+Cone and EUHFORIA2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Three CMEs which erupted on 2017 Sep 4 and 6 underwent mutual interaction before reaching Earth on Sep 6-9, where it gave rise to a complex and unexpectedly geoeffective structure as detected by WIND at L1. The spacecraft first observed an interplanetary (IP) shock on Sep 6 followed by a turbulent sheath. The leg of the CME flux rope is detected on Sep 7, in which clear signatures of a shock-in-a-cloud can be distinguished, coming from the third CME which propagated into the preceding flux rope. We model the source of this complex ejecta with WSA-ENLIL+Cone and EUHFORIA to assess and compare the overall performance for interacting CMEs as opposed to single CME events.

    We find that following the conventional algorithm for determination of input parameters give large deviation in the event prediction at L1. The overestimated density of the IP shock 1 is due to the way of implementation of the magnetogram in WSA model. Excluding the slow CME from the input leads to even larger deviation. The prediction of IP shock 1 drastically improves by introducing of a customized density enhancement factor (dcld) based on coronagraph image observations. This novel approach, is simple and accessible, and could be applied to improve the forecast for fast, undisturbed CMEs. The deviation in the prediction of IP shock 2 comes from its interaction with the low proton temperature environment of the preceding magnetic cloud, giving rise to an expansion of the shock front. Additionally, the properties of the background solar wind plasma have been preconditioned by passage of the previous IP shock. This was confirmed from the kilometric type II radio burst emission following the eruption of the third CME. The propagation profile of this CME implies an almost non-existent deceleration in the interplanetary medium, in contrast to the expected CME deceleration due to interaction with the background plasma.

    In summary, this study presents clear indications that magnetic interaction must be taken into account to reliably forecast multiple CME events. Preconditioning of previous CMEs must also be considered in more depth, and ultimately requires a realistic, time-dependent model of the ambient solar wind which responds well to propagating shock waves. Models in space physics presents us with the perfect tools for understanding not only the physical processes that the simplified models can predict, but perhaps more importantly, help us begin to understand what the models fail to predict.

    Automation and Improved control of Bundle pusher: Automation control2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Newspapers are often bundled and packet on pallets to secure transport. Packing thebundles on pallets are often done with an automatic palletizer. For reliable operation,the bundle needed to have a correct position and orientation on the infeed conveyor.Wrong orientation can happen when the bundle is pushed from conveyor to thepalletisers conveyor. The main to reasons is wrong timing that leads to rotation of thebundle and to high pushing force that leads to tumbled bundles. The goal of thisproject is to make a prototype of a system that automatically adapts the pressure andsignal when to push using two laser sensors. One sensor sends a digital signal if laserbreaks, the other measure distance, e.g. bundle hight. The software was developed onan Arduino Uno board, and two interface board was made for voltage levelconversions. The prototype system managed to change pressure for different bundlesizes and timed the pushing signal correctly.

    LEAN-baserad processoptimering av parental nutritionstillverkning: En teoretisk optimering2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Fresenius Kabi is a company specializing in clinical nutrition, infusion therapy and medicinal technology. Fresenius Kabi has two production facilities in Sweden, one in Brunna and one in Uppsala. The production facility in Brunna supplies the facility in Uppsala with the raw materials needed to create ampules of anesthetics, bags of parental nutrition, vitamin solutions and many other medicinal products. Fresenius Kabi has recently made a big investment in a software program called PAS-X which is designed to store and control the flow of information during production of the company’s various products. This information is currently written by hand on paper in batch protocols and stored for up to 10 years as part of the company’s quality assurance. The problem with PAS-X and the motivation behind this thesis project is that the production and production information therein is not optimized to be controlled electronically. The production layout and processflow have been largely adapted with manual information storage in mind, making a direct transition to electronic storage problematic. This project was ordered by the PAS-X project group at Fresenius Kabi where the goals were to analyze the production layout and production flow and subsequently rearrange the production layout and revise the process using a LEAN methodology. By identifying and eliminating areas of waste and also standardizing the production of one of the company’s main products, SMOFKabiven, this thesis and the work behind it was able to theoretically reduce transportation distance during key moments by 65 %, the time to complete selected operations by 40 % and manpower necessity by 50 % in 75 % of analyzed work operations.

    Conceptual Development of an Automated Corrugated Cardboard Box Filler2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The project aimed at conceptually develop a solution that is able to automatically transfer an already stacked and measured heap of goods from an order tote into an erected corrugated cardboard box, whereas the dimensions of the corrugated cardboard box and the stack are allowed to vary within a specified interval.

    The method for this project consisted of five main parts: feasibility study; concept generation; concept choice; design; and evaluation.

    The project was initiated by a feasibility study where the problem was clarified and knowledge regarding the problem was gathered. The feasibility study resulted in an user requirement specification and a product requirement specification. The product requirement specification was utilized in the evaluation processof the final developed concept.

    The concept generation was conducted according to structured methods prescribed by Ulrich and Eppinger. The concept choice was done by the use of Pughs concept choice matrix.

    The result of this project consists of a conceptual proposal of how the previously described problem may be solved. The final developed concept resulted in a cad model. The evaluation showed that the concept did not fulfill the product requirement specification, despite this it is assessed that the concept in its working principle has good merits that are worth further investigation.

    Further development of the concept remain and validation of the working principle is needed. Further choices concerning form, material, and components remain. The report contributes to a foundation for further development of an automated filling mechanism for erected corrugated cardboard boxes.

    Delineation of Ditches in Wetlandsby Remote Sensing2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Wetlands have been heavily affected by human-alteration, this is done to drain thewetland so that the ground can be used for other purposes such as forestry oragriculture. With high accuracy data available now, it is possible to use differentmethods automatically to identify these ditches in wetlands or other areas. Fourdifferent methods were applied to two areas to delineate ditches.

    To compare the different methods, the results were quantified by comparing with amanually created map of the ditches. Drainage density and an agreement index wereused. The results indicate that the methods of impoundment index and map gullydepth are best able to distinguish the ditches in wetlands. The former gave a betterresult on areas inside wetlands while the latter gave a better result with non-wetlandareas. The other two methods make mistakes and misjudgements that givemisleading results, they ignore ditches partially or completely, or finds ditches inareas without them. Even so, all methods are at least a clear improvement over thecurrently available property map's water flows, but not in the same class as the timeconsumingmanual method.

    Analys av bottensediment från västra Gotlandsbassängen i Egentliga Östersjön2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This project aimed to investigate sediment salvaged from an area in the westernGotland basin of the Baltic Sea. The Baltic Sea is a stressed brackish water sea withextensive eutrophication problems, so-called dead zones and threatened fauna. Theresults relate to phosphorus content, prevalent metals, mineral composition, grainsize distribution, and organic content. This work is part of a project where the goal isphosphorous recovery for concrete and phosphorus mining with circulation andcircular economics to better the current situation in the Baltic sea. The physical andchemical properties of the sediments were investigated using the following analyticalmethods: ICP-MS, XRD, TGA and laser diffractometer together with RISE CBI.The results show that the sediment is a postglacial silt gyttja, with a phosphorouscontent of 1.63 mg / kg of dry sediment (DS). Existing minerals are albite, quartz andmica. Elements found were, but not exclusively silica, 214000 mg/kg DS, aluminium80600 mg/kg DS and iron 49900 mg/kg DS. Relevant purification and separation processes for phosphorus and metals, of which the Bio-P method and hyper-accumulating plants are two, are discussed.

    Since its introduction by Gibson (1979)the concept of affordance has been debated by a number of researchers. Most famous, perhaps is the disagreement between Gibson and Norman(1988)about whether affordances are inherent properties of objects or are only present when perceived by an organism. More recently, affordance has been drawn on in the educational arena, particularly with respect to multimodality (see Fredlund, 2015 for a recent example). 

    In the presentation the interrelated concepts of disciplinary affordance and pedagogical affordance will be presented. Both concepts make a radical break with the views of both Gibson and Norman in that rather than focusing on the perception of an individual, they refer to the disciplinary community as a whole. Disciplinary affordance is "the agreed meaning making functions that a semiotic resource fulfills for a disciplinary community". Similarly, pedagogical affordance is "the aptness of a semiotic resource for the teaching and learning of some particular educational content" (Airey, 2015). As such, in a teaching situation the question of whether these affordances are inherent or perceived becomes moot. Rather, the issue is the process through which students come to use semiotic resources in a way that is accepted within the discipline. In this characterization then, learning can be framed in terms of coming to perceive and leverage the disciplinary affordances of semiotic resources.

    Musikbiblioteken i kulturpolitiken: En diskursanalytisk studie av musikpolicy i två statliga myndigheters biblioteksverksamhet i förhållande till rådande kulturpolitik2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This paper examines the way music in libraries is described in the current state cultural policy as laid out mainly in two government bills which form the basis for Swedish cultural policy. By using discourse analysis as its research method, it examines the way music and libraries are described in current cultural policy and the role music libraries are given as a part of this policy. It then looks at the way this discourse is reflected in Swedish libraries by examining the way two state owned cultural institutions treat music in their library activities as stated by them through their publicly accessible policy documents and information given on their web pages. Official cultural policy is compared to how the two institutions speak about their music library work in order to deter-mine whether or not the discourse on music libraries in the examined documents is one and the same. The re-sults of this two-part analysis were compared to a couple of common cultural discourses using a method inspired by discourse analysist Norman Fairclough with the goal of determining whether the discourses on music in cul-tural policy and in the libraries are indicative of or influenced by other common discourses in society.Results showed that there is no explicit policy concerning music libraries in Swedish cultural policy. In so far as the state is willing to actively support music, this involvement is largely concentrated in one single institution, Statens musikverk, which is also one of the two state owned cultural institutions examined in this paper. The goals of this institution as stated both in one of the government bills examined and in their own policy docu-ments are two-fold, and concerns music as a part of the Swedish cultural heritage and the uplifting and support of Swedish musical life. Overall the state is quite reluctant to interfere in the cultural sphere, an attitude which stems from an established tradition in Swedish politics and a Western view of culture and art as an autonomous region in society. There are however certain attitudes towards libraries, music and culture in general present in current cultural policy, one of the more important for this investigation being that libraries and music are treated as belonging to different areas of cultural policy. Where libraries are associated with learning, democratic values and literature, music is treated as part of a group of other expressive or scenic arts such as theatre and dancing.

    Det friska på sjukhuset: En kvalitativ intervjustudie om användares och bibliotekariers syn på patientbibliotek2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim for this master’s thesis is to clarify users’ and librarians’ views on patient libraries today. This aim is achieved by answering the following research questions: Which are the most important functions and tasks of the patient library, according to users and librarians? Which views on the patient library’s activity come with these functions and tasks? How does the connection to different cultural institutions, such as the library and the hospital, affect users’ and librarians’ views on the patient library? In what ways is the patient library regarded as an asset for health care? As a background for my study, and to give a context to the results, a historical background on the evolvement of hospital libraries in general, and of the case of S:t Görans patient library in particular, is given. Previous research on the subject of hospital libraries from different perspectives is presented and discussed. Aspects such as the hospital library as a bearer of cultural activity, hospital libraries as information centers and collaboration between library and hospital are discussed. Studies from the field of culture and health, about how cultural activity can improve patients’ health and about how health professionals can benefit from reading fiction, are included in the background of the thesis. The theoretical framework is a sociocultural perspective based on the works of Roger Säljö, with the concept of cultural institutions as a tool to analyze the views on the patient library. The method used is qualitative semistructured interviews with library users and librarians.  One of the tasks and functions that arise from the interview is to make literature available for more people. Another is to be a calm room within the hospital. The conclusion is that the patient library has a strong connection to the public library as well as to the hospital. Users connect the patient library more to the public library, but the function of being a part of the hospital is important too. The librarians connect the patient library strongly to the public library. At the same time, they express loyalty towards the hospital.

    Vad betyder läsfrämjande?: En kvalitativ studie över det läsfrämjande begreppets narrativa uppbyggnad på svenska folkbibliotek.2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this master thesis is to examine the Swedish term for reading promotion, läsfrämjande, and gain a greater understanding for the meanings inherent in the word. To do this, narrative theory in the form if Harding's typology of six different types of narratives arranged on a scale from general to particular has been used for the analysis.The study focuses on librarians that work with children and young adults in public libraries and their rela-tionships with reading promotion. On the surface the Swedish word for reading promotion is simple, but exam-ined closely it becomes apparent that it is in fact multifaceted. The word consists of many different narratives that interact and in different ways change and affect each other. This study has identified five different types of collective narratives connected to the word läsfrämjande. These are the democratic narrative, the narrative of qualitative litterateur, reading for the soul, the enabling narrative and the literacy narrative. Together with the other types of narratives these form the basis of the personal narrative the librarians form around their reading promotion work and the word läsfrämjande.The personal narrative connected to the word will always be unique to the individual librarian, and it is be-cause of this that the word is so hard to define. The meaning will differ in small ways between different people, but because the personal narratives are built from the same collective narratives there will appear to be consensus in the meaning.This study has been produced as a two years master’s thesis in Library and Information Science.

    Ett Stadsmuseum för alla: En studie av uppsökande museiverksamhet i Stockholms ytterstad2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This study examines a project carried out by Stockholms stadsmuseum in the area of Östberga in Stockholm called Stadsmuseet på plats – Östberga. Interviews with museum personnel and analysis of documents related to the project make up the material for this study. The theory used is The Contextual Model of Learning, which in this study is adjusted to apply a museum-centered perspective rather than a visitor-centered one.

    The aim is to examine the intentions behind this type of outreach work and how it relates to the concept of the socially responsible museum. This concept is an expression of the development of the museum towards a visitor-centered, democratic and inclusive institution. It also includes a political idea, primarily in a British context, of the museum as a vehicle for positive social change.

    This study shows that Stadsmuseet på plats – Östberga is connected to larger political goals within the municipality regarding a sustainable social development. The museum’s intentions behind the project combines a regard for the local development of Östberga, with the fulfillment of internal institutional goals relating to audience development, development of museum collections, and creating an inclusive cultural heritage that represents every part of Stockholm.

    This is a two years master’s thesis in Museum and Cultural Heritage Studies.

    Motstridiga motprestationer: En studie om museers finansiella möjligheter och utmaningar2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Introduction This master ́s thesis focuses on the financial situation in a number of museums located in Stockholm, Sweden. In particular the study focuses on external financing and sponsorship and which means that are given to meet the conditions surrounding financial support. The aim of the study is to increase the knowledge of how the financial situation for museums looks like and how the interaction between cultural and economic capital shows.

    Theory The theoretical framework for the study is based on the theory of cultural economics and Pierre Bourdieu's theory of cultural / economic capital and his concept of space. The study used Bruno Freys terms Superstar Museumsand thetotal experience.

    Method The main method for the study was a comparative method, but a mixture of quantitative and qualitative methods were also applied in the study. Interviews were conducted with informants from a number of the museums and data from all the selected museums was collected and compared. The material also consisted of a variety of written material, mostly annual reports, but also news articles, reports and official documents.

    Analysis & Results The material shows a wide range of factors defining the economic situation of museums in Stockholm. A large part of the income comes from public fundings for the public museums. The private museums are more dependent on incomes from admission fees and external financing. For many of the public museums the market based rents for the building is an issue that causes economic distress.

    Conclusions Many museums work with sponsorships and have a positive view on external collaborations, at the same time the majority of the museums report a low revenue from sponsorships. The legal framework makes it more difficult for public museums to work with external financing and the taxation system aggravates sponsoring in museums. The free admission reform was both criticized and applauded and divided the private and public museums.

    Röster från marginalen: Perspektiv på bibliotekets tillgänglighet2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this master’s thesis is to examine the definition of ”accessibility” in regulatory documents for libraries and to study the actual accessibility at Malmö main public library through surveys and a group interview. The study is based on theoretical perspectives like postmodernism, disability studies, queer- and crip theory. The method for this master’s thesis is to study regulatory documents for libraries and to compare the goals in them with results from paper- and webbased surveys and a group interview with five participants. They study the accessibility at Malmö main public library from their point of view. The study shows that the library’s main focus today lies on physical accessibility, whereas results show that this focus needs to be widened to include psychological, cognitive, and sensory accessibility. This could improve accessibility not only for people with disabilities but for all library users. The study also shows that the library environment and services are formed according to a narrowing ableist norm that makes the library accessible for only a minority of library users. The goals set in regulatory documents and the actual accessibility at Malmö main public library are found to differ widely. A lot of measures have to be undertaken to guarantee fundamental rights for people with disabilities and to make the library “accessible for all”, as it says in the Swedish library law. This study is a two years master’s thesis in Library and Information Science.

    Arkiven och allmänheten: En undersökning av marknadsföring inom arkivsektorn2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This paper constitutes an investigative analysis of how marketing is utilized in public archives in the municipality of Uppsala. By studying and contrasting two local archives and putting these findings in a wider marketing context this paper hopes to answer several questions about how archives market themselves: How important marketing is considered as an aspect of archival work, How highly marketing is prioritized in regards to archive resources and funding, how traditional and social media impacts the marketing landscape and effort of the archives, what differences in methodology occur between the two archives and what constitutes the basis of these differences, and how the economic terminology of marketing is used in archives as cultural institutions. The conclusion is that marketing is becoming an increasingly important aspect of the archival business model and that several channels for marketing archives, both digital and analogue, are seeing greater utilization. Archives are in the process of departing their role as passive conveyors of information and are adopting models for a significantly more active interactions with the public.

    Bernhard Schmidts kvarlåtenskap och det globala kulturarvet2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This master thesis is about the Estonian-Swedish astro-optician Bernhard Schmidt (1879-1935) and his legacy. He was born on the island of Nargö outside Tallinn in Estonia. In 1930 he invented a special optical system for telescopes called the Schmidt telescope or Schmidt camera. At that time Bernhard Schmidt was working as a freelance at the Bergedorf observatory outside Hamburg in Germany. His invention contributed to astronomical research which changed our view of the sky and of the universe. The time he was living in was politically turbulent and science was flourishing. The written sources about Bernhard Schmidt and his telescope are mainly published in German, Russian, Estonian and English. Almost nothing is published in Swedish. The sources to his personal history and the archive material concerning him are partly scattered and it is difficult to assemble a complete picture.

    The purpose is to find and to map out what kind of archive material is preserved about him. The aim is also to find out who is in charge of it and how accessible it is. Is there global access to the material? Observatories, museums and archives in Sweden, Germany and Estonia were visited to map his legacy. The theories of James Cuno (2008) and the triad or three principles of management: preservation, knowledge and access were used in the analysis of the findings. Most material is kept and preserved at the Hamburg Bergedorf observatory, University of Hamburg. This is also the place where Bernhard Schmidt spent the last years of his life and it is here we can find his burial site. At the Hamburg Bergedorf observatory today there is a Bernhard Schmidt archive, a Schmidt museum with the first prototype of his telescope and an archive of photographic plates with photographic pictures of the stars and other astronomical objects. The two archives are in a digitalizing process and when completed they will be globally accessible and a part of our global heritage.

    Uncommon vocabulary in mathematical tasks in relation to demand of reading ability and solution frequency2015In: Nordic Studies in Mathematics Education, Vol. 20, no 1, p. 101-128Article in journal (Refereed)
    Abstract [en]

    This study reports on the relation between commonness of the vocabulary used in mathematics tasks and aspects of students’ reading and solving of the tasks. The vocabulary in PISA tasks is analyzed according to how common the words are in a mathematical and an everyday context. The study examines correlations between different aspects of task difficulty and the presence of different types of uncommon vocabulary. The results show that the amount of words that are uncommon in both contexts are most important in relation to the reading and solving of the tasks. These words are not connected to the solution frequency of the task but to the demand of reading ability when solving the task

    Water chemistry and runoff in forest streams at Kloten1982Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Natural variability of stream water composition and discharge was studied in the Kloten area, Central Sweden, by means of statistical methods and simulation technique. The effects of Urea (155 kgN ha-1) and ammonium nitrate (AN, 160 kgN ha-1) fertilization and clear-cutting were studied by comparing treated and reference streams before and after management.

    The concentrations of the chemical constituents and runoff were mostly inhomogeneous in space and time and the coefficients of variation were considerable.

    Urea fertilization had a more prolonged nitrogen leaching and a total of 750 kgN km-2 compared with AN treated areas (500 kgN km-2). The difference was due to higher nitrate leaching. Base cation leaching was larger and pH increased after Urea fertilization. pH decreased after AN fertilization.

    Runoff increased 180 mm year-1 after clear-cutting, while no significant change was found after fertilization. The immediate effect of clear-cutting on stream water chemistry was an increase in dissolved organic matter, followed by increased leaching of ammonia (10x), nitrate (9x) and potassium (4.8x). The total excess leaching of nitrogen was 1 040 kgN km-2 during the first three years after clear-cutting.

    A Norwegian hydrochemical model, that explained stream water composition, was modified and parameterized (40 parameters) for two catchments to analyse differences between them.

    The differences in parameters between the catchments were interpreted as differences in slopes close to the drainage net, dilution due to different evaporation, differences in standing biomass and current annual increment and slightly different mineral composition of the soils. pH at high flows could be deduced from stand characteristics.

    Dagkirurgi-patienters upplevelse av den fysiska och psykosociala vårdmiljön2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Knowledge about the importance of nursing environment and patients’ participation in its design promote patients’ well-being. In person centred care, environment is an important component of the human healing process. The aim of this study was to describe the experience of the physical and psychosocial nursing environment in women who underwent day surgery due to breast cancer from registration to immediately before sedation. The method used was qualitative semi structured interview study. Strategic selection was used to recruit informants where eight patients participated. Qualitative content analysis was chosen to analyse the data. The results showed that the informants had a positive experience of the nursing environment at the department. Described experiences in the physical nursing environment varied but were generally positive. Clean and friendly environment was important for the informants’ experience. A “just like home” experience was described. Having a private room was highly appreciated by the informants, which they associated with experienced integrity. However, there were experiences of deficiencies in how integrity was preserved in the common waiting room due to its design. Experienced professionalism and skills in the nursing staff resulted in a sense of security and trust. The nursing staff’s good working methods and patient treatment created a sense of harmony and security that was experienced as calming. In conclusion, the department’s nursing environment affected the informants' experience generally positive. Although the experience of the physical nursing environment was described as not optimal, experience of the psychosocial nursing environment and good patient treatment outweighed the informants' overall experience.

    Kvinnor och mäns smärtskattning och smärtbehandling efter dagkirurgi ur ett jämställdhetsperspektiv2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Acute postoperative pain goes undertreated to a large extent. Previous studies have shown that women experience more postoperative pain than men, although it’s unclear whether women receive the equivalent amount of pain relief to that of men. Multimodal pain management is recommended to optimize postoperative pain relief. This needs to be studied further, to clarify whether pain management is gender equal in outpatient surgery.

    Aim: To study postoperative pain from a gender equality perspective at an outpatient surgery center, and to examine whether there is any difference in pain intensity and pain management between men and women.

    Method: The study was a descriptive cross-sectional study with a quantitative approach, including data collection from medical records and patient data management system. The study was conducted at an outpatient surgery center in central Sweden, and included 69 patients, 37 women and 32 men, ASA 1-3. Pain was measured with NRS verbally, <1 h, 2 h and 24 h postoperative. Pain management data was collected from a patient data management system.

    Results: Women experience statistically significant more pain within the first postoperative hour and received statistically significant less opioids than men. Women had a tendency to receive less NSAID and multimodal pain management than men.

    Conclusion: Postoperative pain management after outpatient surgery is not gender equal. Women should receive more opioids and NSAID when possible to optimize postoperative pain relief.

    Ditt, mitt eller vårt?: Bronsålderns ekonomiska system vid Pryssgården och Apalle2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Bronze Age in southern Sweden is a period that has seen a great deal of research for as long as archaeological studies have been undertaken in this country. While we have a rich material record and even many visible indicators of the time in the landscape, such as the rock carvings of Tanum and the many mounds dotting the landscape, many aspects of that society are relatively poorly understood. I´m mainly referring to the economic structures underpinning Bronze Age societies. This project will take the models of Wealth and Staple Finance Systems, developed by Timothy Earle and successfully tested in many equivalent contexts around the world, and apply them on Swedish settlement materials from the Bronze Age settlements of Pryssgården and Apalle. The study looks at site distribution patterns, the prevalence of prestige goods and the possible importance of external contacts in order to produce a reliable economic model of the Swedish Bronze Age. While some similarities in resource management are obvious, some relevant aspects were found to differ.

    Understanding state repression in the light of gender equality: Exploring under which conditions states use violent repression toward violent and nonviolent dissent2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    States respond to dissent with repressive means to stay in power. However, there are observed variations in how violently this repressive behavior actually is. Drawing on theories using gender inequality as one of the main, but often dismissed, determinants of violence and armed conflict, the thesis hypothesizes that attitudes to gender equality can help explain the variations in state repression. The theoretical argument is grounded in how gender norms characterized by militarized masculinities shape conflict norms since it is related to how ‘others’ in general are treated in society. By employing regression analysis, and testing the relationship between gender equality, operationalized through the Women’s Political Empowerment Index, and state repression in relation to a maximalist campaign, I found statistical support for the hypothesis that at higher levels of gender equality, repression is less likely to be extreme. The results also suggest that previous repressive behavior matters and that the severity of repression depends on the primary method of resistance within the campaign as well. The thesis thus further reinforces the importance of incorporating gender equality when attempting to explain collective violence.

    Making or Breaking Peace: Understanding Diaspora Attitudes Towards Homeland Conflicts2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Conflicts today aren’t just between two opposing parties but are delocalized for many reasons. One of those reasons is the migration of groups affected by conflict to other countries. These groups are known as Conflict-generated diaspora and even though they move across the border, they never really cease to be involved in the conflict back home. Because of this continued attachment, diasporas can play the role of a peace-maker or a peace-breaker in the homeland conflict. The literature on diasporas is still trying to understand the factors that lead to this behavior. In this context, this study attempts to answer the question - How does migration affect attitudes towards peace deals for homeland conflicts?I conduct a Structured Focused Comparison of Palestinian communities in Palestine and Sweden to test the diasporas as peace-breakers framework, which links conflict-generated migration to negative attitudes towards peace deals for homeland conflicts. The empirical findings do not find support for the hypothesis tested; since the Palestinian diaspora in Sweden showed a more positive attitude towards the Two-state solution as compared to the local Palestinian community. This is an important finding because it makes a strong case for not labeling all conflict-generated diasporas as peace-breakers.

    'Nobody wants to get into the jungle': Explaining strategy based on restrained offensive operations and peacekeeping effectiveness.2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    No study has so far documented the characteristics of a military strategy based on offensive operations and whether they influence the security situation in the areas in which they are launched. Yet, it seems extremely important to study because there is a growing trend in Peacekeeping Operations of becoming more robust in the use of force by applying this kind of military strategy. This study aims to develop a new theory to explain the short and long term effects of applying a military strategy based on offensive operations which are politically restrained in the use of force and asks to what extent it affects it. Deriving from war and peace research, this study argues that when a strategy based on restrained offensive operations is applied, it is likely that stability improves in the short term but deteriorates in the long term presenting a ‘V’ shape effect. This is because the political restriction on the use of force does not allow achieving a decisive victory. Using the method of structured focused comparison, most similar case, the suggested hypothesis is tested on two UN sectors belonging to the United Nations Organization Stabilization Mission in the Democratic Republic of the Congo. The results show some support for the theorized relationship, although the ‘V’ shape was less pronounced than expected. Hence, further research is needed to refine the causal mechanism suggested. This study does not provide empirical evidence, neither should be interpreted that in order to make Peacekeeping Operations more effective it is necessary to conduct full-fledge offensive operations.

    The ATLAS-upgrade is a project with the endeavors to enhance the performance of the ATLAS detector located at CERN. The intention of this project is to enable testing of the upgraded components locally at Ångströmlaboratoriet, Uppsala University, in cooperation with CERN. A power supply system  was constructed to provide the correct voltage to the new electronic hybrid circuits. The hybrids need to be tested under the right conditions hence governing the features of the system. A graphical user interface with included software that controls and monitors the hardware in the system was developed. To ease connection of the test system, a backplane power circuit board was designed for the power supply cards.

    Adaption of IP-stack for a microcontroller2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    An adjustment of the IP stack to a microcontroller has been attempted.The Ip stack manages IP traffic, which occurs through incomingoutgoing data packets, and these packets are attempted to be storedwith call buffers instead of current implementation. Programming wasdone in C, and a lot of time was spent looking through currently usedcode in order to better understand how it functioned. Data packetswere then sent from a computer to the microcontroller, and by printingout variable locations and sizes, an understaning of how the stackworked and were data were stored, could be reached.The project led to the insight that the project was more difficultthan first estimated, the reason being that much of the software wasbased on the handling of data packets. The project resulted in anincreased understanding of how the adaptation can be implemented, andhow the current stack actually works.

    Thermo-mechanical analysis of cryo-cooled electrode system in COMSOL2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the planned linear accelerator called Compact Linear Collider, CLIC, electrons and positrons will be accelerated to velocities near the speed of light. A limiting factor in accelerating structures are vacuum breakdowns, which are electrical discharges from a surface as a result of a large electric field being applied. In the preparatory studies for the CLIC, Uppsala University in collaboration with The European Organization for Nuclear Research, CERN, is building a DC Spark system to analyze vacuum breakdowns. This system containing large planar electrodes will be cooled down all the way down to around 4 K in order to limit the rate of wich vacuum breakdowns happen. When cooling a system like this, which consists of different components made of different materials there is the question of how the system will be affected. The objective of this project is to investigate how the cooling will affect the stability in terms of stresses and to analyze the cool down time of the system. Another goal is to make a material recommendation for a few parts based on the results. This will be done by simulating the cooling in COMSOL Multiphysics, which is a program that uses finite element analysis to solve complex problems where different branches of physics interact. The conclusion is that the system will most likely be stable as it is and there is no need to redesign it. The choice of recommended material is alumina with the reason being it should cause the least stress and the smallest gap between the electrodes when the cooling is done. There was no big difference in the cool down time between the materials. Further studies and simulations on the system is also recommended since there are many factors not taken into consideration in this study.

    The earth trembles before cryptocurrencies; but how does a blokchain-based smart money platform perform?2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Swedish central bank has in 2018 launched an investigation into what a digital e-currency in Sweden would look like. Tendermint is being investigated for a potential implementation. Tendermint is a blockchain building environment which has its own consensus-algorithm, and its own solution to the Byzantine general's problem. The most relevant part is the scalability and reliability of Tendermint. To do this we tested out the software by sending transactions between our computers, and recorded its performance in the case of one node and two nodes. After a series of simulations, we then come to the conclusion that indeed Tendermint is a suitable software for a potential e-krona.

    The Crystal Size Distribution of Cerro Bayo2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    To understand the complex structure of magmatic plumbing systems beneath volcanoes, one needs to study the different textures shown in the igneous rocks produced by the volcano in question. By doing this, one can get a clue of the processes that resulted in the final rock. One of the most important methods to use for studying rock samples is the Crystal Size Distribution (CSD), which can reveal a great amount of information about the history of the rock and give an insight in the journey of the crystals during their time in the magma. An extinct volcano named Chachahuén, located in Argentina, South America, was chosen for this study. Samples of rock were collected from one of its laccoliths named Cerro Bayo and was identified as hornblende-bearing dacite. The difference in crystal size was very significant in these samples, with both larger and smaller crystals embedded in the same matrix. This is interesting considering the fact that large crystals form by slow cooling of the magma while smaller crystals form as the magma cools rapidly. By studying the CSD and interpreting other textures found in samples of igneous rock, one may interpret different processes which affected the crystals, indicating what the structure of the magma chamber once looked like.

    The secondary spiral lamina and its relevance in cochlear implant surgery2018In: Upsala Journal of Medical Sciences, ISSN 0300-9734, E-ISSN 2000-1967, Vol. 123, no 1, p. 9-18Article in journal (Refereed)
    Abstract [en]

    Objective: We used synchrotron radiation phase contrast imaging (SR-PCI) to study the 3D microanatomy of the basilar membrane (BM) and its attachment to the spiral ligament (SL) (with a conceivable secondary spiral lamina [SSL] or secondary spiral plate) at the round window membrane (RWM) in the human cochlea. The conception of this complex anatomy may be essential for accomplishing structural preservation at cochlear implant surgery.

    Material and methods: Sixteen freshly fixed human temporal bones were used to reproduce the BM, SL, primary and secondary osseous spiral laminae (OSL), and RWM using volume-rendering software. Confocal microscopy immunohistochemistry (IHC) was performed to analyze the molecular constituents.

    Results: SR-PCI reproduced the soft tissues including the RWM, Reissner's membrane (RM), and the BM attachment to the lateral wall (LW) in three dimensions. A variable SR-PCI contrast enhancement was recognized in the caudal part of the SL facing the scala tympani (ST). It seemed to represent a SSL allied to the basilar crest (BC). The SSL extended along the postero-superior margin of the round window (RW) and immunohistochemically expressed type II collagen.

    Conclusions: Unlike in several mammalian species, the human SSL is restricted to the most basal portion of the cochlea around the RW. It anchors the BM and may influence its hydro-mechanical properties. It could also help to shield the BM from the RW. The microanatomy should be considered at cochlear implant surgery.

    The discolouration of Hyaluronan in presence of phosphate buffer2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Hyaluronan is a polymer that among other things is used in fillers. Products containing Hyaluronan is sometimes discoloured over time and the mechanism behind this discolouration is still unknown. However, it was suspected that discolouration occurs during the degradation due to high pH values or with a phosphate buffer. The discolouration of Hyaluronan that occurs with phosphate buffer was studied in more detail in this project. The samples of Hyaluronan with different concentrations of phosphate buffer were left at 90 °C in an oven to speed up the discolouration. These samples were then analyzed byusing UV/Vis spectrophotometry to measure the absorption and capillary viscometry to measure the molecular weight. The results showed that the discolouration increased with time and that the samples with the higher concentration of buffer got more discoloured faster. The molecular weight showed a decreasing trend with time. It also suggested that the phosphate buffer had an impact on the molecular weight. The samples with the highest concentration of phosphate buffer had a lower molecular weight compared to samples with no phosphate buffer. The main conclusion from this study is that the phosphate buffer had an effect on the discolouration of Hyaluronan.

    More secure attachment to the father and the mother is associated with fewer depressive symptoms in adolescents2018In: Upsala Journal of Medical Sciences, ISSN 0300-9734, E-ISSN 2000-1967, Vol. 123, no 1, p. 62-67Article in journal (Refereed)
    Abstract [en]

    Aim: To investigate whether more secure attachment to the father and the mother is associated with less depressive symptoms among adolescents, and to explore possible sex differences.

    Method: A population-based sample of adolescents completed a school-based survey assessing demographic data, attachment to father and mother, as well as depressive symptoms. Participation rate was 80% of the eligible population, and 3,988 adolescents (1,937 boys and 2,051 girls) had complete data for the analyses.

    Results: Paired samples t tests showed that participants rated their attachment to mothers as slightly more secure than their attachment to fathers (t = 15.94, P < 0.001; boys: t = 5.23, P < 0.001; girls: t = 16.16, P < 0.001). In linear regression analyses there was an association between the outcome, number of depressive symptoms, and more secure attachment to the mother for boys (B=-0.532; 95% confidence interval [CI] -0.656, -0.407, P < 0.001) and for girls (B = -0.623; 95% CI -0.730, -0.516, P < 0.001). Analogous results were found for more secure attachment to the father for boys (B = -0.499; 95% CI -0.608, -0.391, P < 0.001) and for girls (B = -0.494; 95% CI -0.586, -0.401, P < 0.001).

    Conclusions: Understanding the relationship between attachment to both father and mother and depressive symptoms in adolescent boys and girls is essential for further development of strategies for prevention and treatment of depression.

    ”Om man inte lyssnar på musik så kan man höra om någon går bakom en”: En kvalitativ intervjustudie om upplevd (o)trygghet i Uppsala2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Studiens övergripande syfte är att studera hur kvinnor och män rör sig i offentliga rum med upplevd (o)trygghet som utgångspunkt. Studien ämnar också undersöka vilka trygghetsskapande strategier som används och vilka åtgärder inom samhällsplaneringen som kan göras för att en stad ska upplevas som tryggare. En fallstudie i Uppsala med kvinnliga och manliga studenter har genomförts för att uppnå syftet. I studien används en feministisk metodologi och semistrukturerade kvalitativa intervjuer har genomförts.

    Undersökningen visar att kvinnorna upplever mer otrygghet och är mer begränsade av sin otrygghet än männen. De flesta av männen berättar att de upplever otrygghet i mötet med, exempelvis en hotfull person som har kniv, medan kvinnorna berättar om sin otrygghet som en mer generell känsla, exempelvis när det är mörkt på kvällen, eller vid möten med män, farliga eller ofarliga. De flesta av informanterna, även de som upplever sig vara helt trygga, använder sig av trygghetsskapande strategier. Vanligast är att undvika att lyssna på musik i hörlurar när det är mörkt ute för att vara mer uppmärksam på omgivningen. Som åtgärder på hur samhällsplaneringen kan bidra till ett tryggare samhälle nämndes huvudsakligen ökad närvaro av polis och vakter, förbättrad belysning och planering som leder till att människor befinner sig på platser.

    Investigating the properties of Planck's radiation law through theoretical and numerical studies2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A black body is an ideal object that absorbs all incident electromagnetic radiation and simultaneously emits radiation that only depends on the temperature. The radiation is described by Planck's radiation law and its maximum by Wien's displacement law. The aim of this project is to study Planck's and Wien's laws in the frequency and wavelength domains, by theoretical studies and numerical studies in the programming language Python. Planck's law can be derived by regarding a cavity where the internal radiation either can be regarded as waves or as a gas of photons. In this study, the main focus lies in the derivation assuming radiation can be treated as waves, which uses the Maxwell-Boltzmann distribution. This derivation is also used when the radiation is simulated numerically in Python. The numerical studies use the stochastic method "hit and miss" to generate the different properties of the emitted radiation. Planck's law occurs in many different forms, the differences between some of them is explained in this project.

    When transforming between the domains one must use a Jacobian. If this is forgotten Wien's law, which is derived from Planck’s law, efficiently shows how the peaks of the correct and the transformed curves are at different positions. The results show that Planck's law accurately can be derived numerically. Even though the chosen method successfully reproduces the Planck distribution the program can be improved by using the inverse transform method for sampling. To study this subject further one could consider deriving and simulating the Maxwell-Boltzmann distribution.

    Medborgardeltagande vid fysisk planering: En studie kring medborgardialoger i Eriksberg2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Medborgardialoger i fysisk planering blir allt viktigare och dess plats allt mer självklar. Det finns oändliga möjligheter för dess utformning och vad som blir bäst beror på plats och situation. Härav blir det intressant att närmare undersöka hur Uppsala kommun har arbetat med medborgardialoger vid framtagningen av planprogrammet för Eriksberg. Arbetet syftar till att undersöka vilka förutsättningar medborgarna ges att delta i den fysiska planeringen. Vidare undersöks vilka problem som finns vid medborgardialoger och hur väl arbetet stämmer överens med kommunens styrdokument. Kanske finns det situationer där medborgardialoger inte ens är önskvärt. Genom en kvalitativ studie bestående av intervjuer och en dokumentanalys i kombination med tidigare forskning framkommer att det svåraste för kommunen är att skapa tillfällen där alla berörda har möjlighet att delta på lika villkor. Genom olika strategier arbetar kommunen med att öka deltagandet genom till exempel utskick av vykort och visst uppsökande av särskilda grupper. I kommunens arbete förekommer tillfällen där medborgardialoger inte alltid är positivt, det handlar främst om en avvägning när i planeringsfasen medborgarna släpps in för att de ska bli produktiva dialoger. Denna avvägning, likt alla andra beslut kring hur medborgardialoger utformas och vilken roll medborgarna ska få är upp till kommunen att bestämma.

    Den vertikala blandstaden: En kvalitativ studie av Karlastaden i Göteborg2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Studien tar sin utgångspunkt i forskning som berör planeringsideal, vilket handlar om tankar och visioner som formar en stad. I denna studie ska planeringsidealet blandstad undersökas utifrån en svensk kontext, i form av den planerade stadsdelen Karlastaden i Göteborg. Syftet med studien är att undersöka och analysera de utmaningar och motiv som ligger till grund för att bygga en tät och hög blandstad.

    I den teoretiska genomgången belyses tre begrepp som är återkommande i uppsatsen: blandstadsidealet, levande stadsrum och tanken att bygga högt. Undersökningen grundas på en kvalitativ forskningsansats där intervjuer har genomförts med aktörer, som är eller har varit engagerade i projektet Karlastaden. För att få en klarhet i hur utformningen av stadsdelen kommer att se ut, genomfördes även en deltagande observation under ett informationsmöte, samt en bildanalys för att förtydliga de visioner som handlar om hur stadsmiljön ska komma att se ut.

    Sammanfattningsvis visar resultatet att Karlastaden ingår i ett större stadsutvecklingsprojekt i Göteborg. Det finns faktorer i staden som skapar utmaningar vid planerandet av blandstad, bland annat lyfts de fysiska barriärerna i staden upp samt liv och rörlighetsaspekten. Vidare visar resultatet att den planerade skyskrapan kan komma att markera ut Göteborgs framtida stadsutveckling.

    Tillgänglighet och socioekonomisk segregation: En studie av kollektivtrafiken i Uppsala kommun2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study of accessibility is a field of vast methodological depth. In combination with the study of segregation suddenly this field of science expands, and at the same time asks us even more questions than before. This study asks the question if the segregation factor in combination with income can determine the level of accessibility in an aggregated population. The article explains different approaches to answer these questions and explores a method made available with aggregated public data in combination with data made available from Uppsala’s public transport administration. This process is complex and is much dependent on the context, but both the segregation factor and higher incomes has a significant negative effect on the level of accessibility.
