    Simulation and Construction of a Half-Bridge Class D Audio Amplifier2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Usage of class D audio amplifiers has become increasingly widespread in recent years, mainly due to their high efficiency, which can reach almost 100 %. Class D amplifiers can also be compact, making them suitable for mobile applications. In contrast, the most efficient conventional amplifiers such as class B can reach a maximum efficiency of 78.5 %. The high efficiency of class D amplifiers can be attributed to the switching stage, which in the case of a half-bridge design consists of two amplifying MOSFETs. These MOSFETs are never on at the same time, which minimizes the quiescent current and thereby the power losses. The goal of this project was to design, simulate and construct a half-bridge class D audio amplifier. A working amplifier with 80 % efficiency was built, with power losses occuring mainly in the voltage regulators. Simulations of the amplifier corresponded well with the constructed amplifier apart from issues originating from the aforementioned voltage regulation as well as the triangle wave generator. The goal of the project was achieved and the finished amplifier possessed good sound quality and little unwanted noise. To further improve on the design, better voltage regulation, a full-bridge configuration and a feedback loop could be utilized.

    Contributions of EventWater to Streamflow inan Agricultural Catchment2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In agricultural catchments, hydrological processes play an important role in the export of nutrients. Water that enters a catchment during a rain event (event water) can have different flow paths and residence times. These affect the transport and biogeochemical transformation of nutrients until the water discharges at the outlet where catchments are usually monitored.This work focused on the contributions of event water and pre-event water (water that was already stored in the catchment before a rainfall event) to the stream. The work is necessary for further studies to develop an understanding of the relation of nutrients export and water flow paths. The method was based on isotopic hydrograph separation and performed on existing data. The stable isotope signature of oxygen in water (δ18O) was used as a tracer. A new study is planned using δ18O to distinguish different flow paths and residence times of water, and therefore a sequential rainfall collector was tested and improved for this purpose.The results of the hydrograph separation show that up to 54% of an increased discharge from a rainwater event is event water, but also that data in a higher temporal resolution is needed to quantify contributions of event water to the runoff for all the events. Additional and more advanced experiments of the rainfall collector would be an advantage, but it can also be used in the field as it is today. Based on the analysis and the revised sequential rainfall collector, a sampling strategy for future work is described.

    Visualisering av klimatkompensation: Seeding Solar2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Currently 55 percent of the population in Kenya is without electricity. To apply light and warmth during the dark hours households in Kenya use paraffin lamps. These lamps are both expensive, harmful to health and have a negative environmental impact. With the help from solar panels, more people in Kenya could get access to green electricity. Seeding solar has a vision to let companies and individuals invest in solar panels to get a positive environmental impact and climate compensate for their possible emissions.

    We have created a prototype of Seeding solars website to make donations possible and give the companies and individuals feedback for the investments they have done. The feedback is shown through visualization of the reduced carbon dioxide emissions in relation to how many households that has received electricity from solar panels.

    The result is a working web application with a visual simulation of the reduced carbon dioxide emissions for each individual investor. We have researched environmental topics, developed algorithms and created an infrastructure that supports Seeding Solar on their mission to contribute to sustainable development.

    Fiat iustitia, pereat mundus: The International Criminal Tribunals and the Application of the Concept of Genocide2018Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    The concept of genocide is probably the most debated subject in Holocaust and genocide studies. The political implications to its usage, or resistance to do so, have also been lengthily discussed. Yet, when it came to the legal sphere of the concept it has been mostly descriptive, without much theorizing on the politicization of the convictions of genocide. This study investigates the relation between the International Criminal Tribunals for the former Yugoslavia and Rwanda application of the crime of genocide and how these judgements were informed. Through the court’s transcripts of a number of selected cases, the research will analyze the application qualitatively, identifying the key factors that determined its usage. The analyses rest on the legal and political aspects that influenced the chambers, evaluating which one explains best. The results indicate that there is no single explanation and that both legal and political reasonings merge in the international legal arena. The courts’ decisions have many inconsistencies that cannot be accounted by a solo description. Thus, matters of law interpretation, conflict’s ending, postcolonialism, and legitimacy all take a tool when convicting or acquitting someone for the crime of genocide.

    Africa Online: A Study on the Emulation of Chinese Practices and Policy in the Telecom sectors of Ethiopia and Nigeria2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In recent years, Chinese development efforts in Africa have increased in scope making China the second largest investor on the African content with Chinese MNCs dominating multiple markets across the continent. The author investigates whether there is empirical support for the assumption that there is a correlation between market dominance of Chinese MNCs and similarity in policy and practices to those of China, an assumption based on Eleanor Westney’s study on the emulation of organizational models in late 19th century Japan. To affirm this correlation and describe where it exists, the author examines the regulation of the telecom markets in Ethiopia and Nigeria, two cases where Chinese MNCs have varying degrees of control over the telecom market. Whether or not the studied cases share similarities with the policy and practices of China is studied using the functional method of comparative law as described by Mark Van Hoecke. The study is based on data collected from Freedom House’s reports on freedom on the net which scrutinizes legislation, court cases and the behaviour of government institutions in 65 countries. The author then discusses similarities and differences between the studied cases and China, concluding that the before mentioned correlation does exist to a certain extent and that further research is required.

    “The past cannot triumph over the future”: A Study of Israel’s Legitimation by the Remembrance of the Past, in the United Nations General Assembly 2009-20172018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of the paper is to further discussion on legitimation in international fora, and to contribute to the scholarly debate on the role of the interpretation of the past in state actors’ legitimation. This is pursued by conducting a descriptive qualitative study of Israel’s justification of political claims by remembrance of the past in the General Debate of the United Nations General Assembly, between 2009-2017. In a theoretic framework that bridges legitimation theory and the theory of public memory, it is hypothesised that legitimation aid state actors to define national interests, identify threats, mobilize publics and perceive options. The results demonstrate that legitimation through referring to the past is employed by Israel for a wide variety of contemporary political issues, and that different aspects of the past are recalled for different issues. The conclusion is that legitimation through the remembered past seems to support the hypotheses of legitimation, and that Israel’s political leaders during the studied timespan appear to promote some parts of the past over others for justifying political stances.

    Bedside-rond: Patientens och sjukvårdspersonalens perspektiv2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: The round is a central part regarding planning and evaluating the patients’ health. Healthcare professional are responsible for the person-centered healthcare where the patient is the center of attention, and where the healthcare is based on the patient’s integrity and autonomy. The traditional round is carried out mainly without the patient’s presence.

    Bedside-round (BR) aims at all professions involved with the patient at the patient’s bedside or in a separate room to make the patient involved in his or her own care.

     

    Aim: The purpose of the literature study was to describe whether BR contributes to person-centered care, participation and improved teamwork, from the patients’ and the healthcare professionals’ perspective.

     

    Method: A literature study based on 10 scientific original articles. Databases used in the study were PubMed, CINAHL and SveMed +. The results analysis was based on Graneheim and Lundman's (2004) qualitative analysis method.

     

    Results: The result of this study indicates that the patient and healthcare professionals experience increased participation through bedside-round. Healthcare professionals experience improvement in the outcome of care as the entire healthcare team gets an overall picture of the patient. Several studies confirm that team collaboration improved, and bedside-round contributed to an increased understanding of each other's professional roles. Disagreements concerning the goal of the round came true, but lack of a clear structure also complicated implementation. Communication improved according to several studies, mainly due to the direct communication between relevant team participants.

     

    Conclusion: BR could be introduced as a working model instead of the traditional round. The patients becomes more involved in their care and the collaboration is improved through more effective communication. The result shows that the patient's participation increases but in order to ensure the evidence that the patient experiences that BR contributes to a person-centered care, even more research is needed from a patient perspective.

    "Alla pratar om UX nu...": En kvalitativ studie av UX på två högskolebibliotek2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is to examine how library employees view and work with UX or User Experience. It also examines how they view library users, the library and their own professional roles and how these views are connected with the concepts of documentality, legitimacy and identity. The concept of power is also used. The study was carried out thorough a series of ten semi-structured qualitative interviews with employees at Karolinska Institutet University Library and Linköping University Library and is based on a social constructivist perspective. The results show that UX is viewed as a mindset where one tries to look at the library from the users’ perspectives and adapt the library after their needs. This was seen as a new perspective where the library aims to stand in the users’ shoes. Through the use of methods like interviews, observations and usability tests the informants try to understand their users and their needs. However, there was a strong emphasis on balancing the users’ wishes with the aims and conditions of the library which indicate a strong internal legitimacy. It also shows that UX does not indicate a loss of power in the informants’ minds. The study shows that an emphasis on the users’ perspective can also be linked to the core of librarianship further strengthening the internal legitimacy. The results also show that arguments can be made for the importance of both constitutive and performative documentality in academic libraries today. Among the informants there was a strong emphasis on a communicatively oriented professional identity with its focus om dialogue and cooperation with library users. In conclusion, the study shows that UX can be viewed as a way for academic libraries to cope with the many changes the last decades have brought and continue to be relevant in years to come. This is a two years master’s thesis in Library and Information Science.

    Characterization of a refractory cement and sensor development for temperature measurements in molten steel2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In steel manufacturing, temperature control is a critical parameter, as it is extremely important for the steel quality. In general, disposable sensors are regularly submerged in the melt for temperature measurements. There are commercially available sensors for continuous temperature measurements.

    In this study, a refractory cement is used for encapsulation and carrier of a resistive temperature detector, for continuous temperature measurements in molten steel. This cement is normally used for manufacturing of steel melt crucibles. The work in this study is mostly experimental and consist of characterization of the cement and development of the sensor. The characterization includes the mechanical properties, the thermal shock resistance, the steel melt resistance and obtainable surface roughness, for different powder fractions, water-to-cement ratio, firings and mixing method. Process development was also done for the manufacturing of the sensor element and its carrier system.

    The end goal of continuous temperature measurement in molten steel for more than 60 minutes was not reached. However, functional sensors were developed where temperatures up to 1000 °C were measured during calibrations, and the cement was well characterized.

    Intra-Vehicle Connectivity: Case study and channel characterization2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis was to investigate the feasibility of a wireless architectural approach for intra-vehicle communications. The current wired architecture was compared to a wireless approach based on three prominent wireless protocols, namely Bluetooth Low-Energy, Ultra Wide-Band, and 60 GHz Millimeter wave technology. The evaluation was focused on their potential use within the intra-vehicle domain, and judged by characterizing properties such as frequency, bandwidth utilization, and power efficiency.

    A theoretical study targeting the propagating behavior of electromagnetic waves was also involved. In particular, wireless behavior has been investigated both in general aspects as well as specifically aimed towards the intra-vehicle application. The theoretical study was then concluded and presented with a course of action regarding wireless connectivity. Beneficial design considerations, potentials and challenges were highlighted together with a discussion on the feasibility of a wireless architectural approach.

    Suggestions for future work and research have been given, which include further expansion of targeted protocols, alleviating the restricted security aspects, and extend the physical aspects onto more software based approaches.

    En Kvinnas List: Synliggörandet av kvinnan som subjekt i Ovidius Metamorfoser2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den romerska författaren och poeten Publius Ovidius Naso (43 f.Kr. - 17 el. 18 e.Kr.) hade år 8 e.Kr. skrivit färdigt sitt magnum opus Metamorfoser. Verket skildrar ungefär 250 olika myter eller sagor som alla kretsar kring temat förvandlingar, eller så kallade metamorfoser. Men Ovidius verk har under det senaste århundradet uppmärksammats för dess otaliga skildringar av våldtäkt. Från Jupiter till Pluto, från gudarnas gud till underjordens härskare, skapar Ovidius ett poetiskt universum där våldtäkt är enda sättet för dessa gudar att uttrycka sina karikatyr-artade sexualiteter. I och med att Ovidius porträtterar ett såpass stort spann av sexuella kfgj så formas därmed det mönster som ska komma att brytas med i myten om nymfen Sálmakis våldtäkt på den unga pojken Hermafróditos. 

    Med hjälp av forskare som lagt fram att Ovidius skildrar våldtäktens psykologiska följder på dess offer kan vi i Sálmakis-myten se att det rör sig om något så ovanligt som en kvinnlig våldtäktsförövare. I forskning när det gäller subjektivitet inom mytologiska narrativ, där mannen har blivit det universella subjektet, utifrån vilket allt annat definieras, blir det tydligt att Ovidius också i subjekt/objekt ställer rollerna på sin kant. 

    Alltså skapar Ovidius något unikt i skildringen av Sálmakis där det rör sig om en kvinnas roll som subjekt och våldtäktsförövare. Hon blir placerad jämte mannen. Men det krävs något så brutalt som våldtäkt för att först blottlägga maskulinitetens uttryck för att sedan kunna klargöra Sálmakis roll i myten.

    Att driva ängeln ur huset: En komparativ analys av författarroll och genus i Virginia Woolfs ”Professions for Women” och Karolina Ramqvists Det är natten2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna uppsats är att undersöka synen på författarroll, skrivande och genus i Virginia Woolfs ”Professions for Women” och Karolina Ramqvists Det är natten. Författaren och den som skriver utifrån följande frågeställningar: Vilka hinder för författarskap gestaltas? Vilka er­farenhet­er av kvinnligt författarskap förmedlas? Vilka likheter och skillnader finns i Woolfs och Ramqvists perspektiv? Teorin hämtas från genusvetenskapliga perspektiv, hos främst Simone de Beauvoir och Yvonne Hirdman, samt litteratursociologiska perspektiv från Johan Svedjedal. Undersökningen utförs genom komparativ metod samt närläsning och knyter an till bland andra Anne E. Fernalds och Sue Roes forskning om Woolfs ”Professions for Women”, samt bidrar till ny forskning om Karolina Ramqvists författarskap som är relativt outforskat inom litteraturvetenskap.

    Virginia Woolf anser att författaryrket utgör ett friare alternativ för kvinnor än andra yrken, och ser sin väg till detta arbete som enkel. Hon uttrycker också att hennes val att skriva inte inneburit några problem för omgivningen och att hon inte hindrats av ekonomiska omständighet­er. Ramqvist berättar att hon inte trodde att hon det var möjligt för henne att bli författare i egenskap av kvinna och att skrivandet utgör ett problem för hennes relationer. Hade hon haft högre ekonomisk status menar Ramqvist att hon inte nödvändigtvis hade arbetat som författare. Hon kommenterar Woolfs ”Professions for Women” och menar att Virginia Woolf kunde bli författare just för att hon hade ekonomiskt kapital.

    Woolf lyfter inre omständigheter och genusrelaterade attityder som centrala problem­ för kvinnliga författare medan Ramqvist redogör för yttre omständigheter, som främst är samman- kopplade med omgivningens och offentlighetens förväntningar och krav. Woolf kan sägas göra större anspråk på att hennes erfarenheter ska anses vara en kollektiv erfaren­het hos kvinnliga författare, medan Ramqvist främst diskuterar utifrån ett eget perspektiv. Ramqvist uttrycker exempelvis också en distans mellan sin egen uppfattning om moderskapets påverkan på för­fattarskap jämfört med sina kvinnliga författarkollegor. Woolf diskuterar inte moderskap i sin text men tar sin utgångspunkt i ”ängeln i huset”, som ska förstås som ett ideal och en attityd där kvinnan är insmickrande och uppoffrande mot sin om­givning, samt framstående inom hem och familjeliv. Ramqvist kommenterar Woolfs begrepp och anser det vara Woolfs egen upp­fattning om kvinnoideal. Hon diskuterar inte sina egna omständigheter utifrån ”ängeln i huset”, men det är möjligt att tolka exempelvis hennes yttrande om att göra sig otillgänglig för mäns behov som en del av vad Woolf kallar att döda ängeln i huset: enligt Woolf alla kvinnliga författares uppgift.

    Our Future Destinations: Backcasting for Sustainable Tourism2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The tourism industry has continuously grown in the last fifty years, promoted economic growth and created jobs (UNWTO, 2017). Nevertheless, this industry is impacting and greatly stressing natural environments and societies inciting a transformation towards a more sustainable form of tourism practices (Williams & Ponsford, 2009).

    The United Nations General Assembly declared 2017 as the International Year of Sustainable Tourism for Development (UNWTO, 2016). The purpose of the declaration was to position the tourism industry as a tool to address the Universal 2030 Agenda for Sustainable Development with its 17 Sustainable Development Goals (SDGs) (UNWTO, 2016).

    A backcasting participatory approach was used to explore the roles of the SDGs in creating future sustainable tourism destinations, using Swedish Lapland as a reference. The study uses backcasting as a method together with a literature review and semi-structured interviews to key stakeholders. The study concludes that SDGs are good parameters to describe current scenarios in order to develop desired ones. It also finds that sustainable future tourism destinations are highly connected with environment and society as part of the core experience, resecting traditions and culture. In order to achieve sustainable future destinations legislation, better practices and alternative methods of transportation need to be implemented alongside creating an experience that is based on responsibility towards nature and societies.

    Den normbrytande trenden: En studie om normbrytande barnböcker ur ett queerperspektiv2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen analyserar tre normbrytande bilderböcker för barn i syfte att undersöka hur genus förmedlas samt vad som gör bilderböckerna till normbrytande respektive icke normbrytande. Analysen är uppdelad i två delar: i den första används Gerard Genettes teorier kring paratexter; närmare bestämt bokomslaget. Därefter diskuteras bilderböckernas paratexter utifrån ett övergripande queerperspektiv med fokus på användningen av färg och karaktärsdrag. Analysens andra del utgår ifrån Kristin Hallbergs ikonotext för att undersöka hur genus konstrueras i interaktionen mellan bild och text. 

    Uppsatsen diskuterar hur genus konstrueras i ikonotexten, vilka egenskaper som framhävs och vad de indikerar.  Slutligen resoneras det kring de faktorer som bidrar till om bilderböckerna kan anses vara normbrytande eller icke i förhållande till heteronormen.

    Vem är hon?: Flickskapets konstruktion i två samtida svenska ungdomsromaner2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I flickforskningen har en mängd flickgestalter undersökts. I denna uppsats studeras flickans konstruktion i relation till traditionella genuskonstruktioner och heteronormativitet. Mer specifikt utreds hur kropp och utseende, agerande samt sexualitet porträtteras och förhåller sig till flickskapet. Detta genom att jämföra två samtida ungdomsromaner: Mina smala axlars längtan (2017) av Maria Frensborg och Ingen normal står i regnet och sjunger (2016) av Sara Ohlsson. Metoden består utav en hermeneutisk och komparativ tolkning av romanerna. I analysen framkommer att flickskapen hos de båda karaktärerna ser olika ut, exempelvis hur de förhåller sig till femininitet och feminism, och att detta kan ses som en effekt av bland annat klass.

    Uppföljning av reningsfunktionen i Steningedalens våtmark2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In Märsta, the storm water is contaminated with heavy metals and nutrients (nitrogen and phosphorus) among other pollutants. The water emits to the river Märstaån and further to the lake Mälaren. The wetland of Steningedalen is a pond system that delays part of the stream in Märstaån and purifies the water on its way through the system.

    This independent project is based on investigation of the purification functioning at Steningedalen wetland. The investigation has been done by sediment sampling and analysis. The samples were taken from the inlet and the outlet of the pond system. Chemical analysis has been made on these samples in an accredited laboratory. The results were compared in order to see if there is a trend through the system. Five sediment traps were placed in parts of the system to study the distribution of the sediment and the need of dredging.

    The results of the study have concluded that the stormwater pond system has a good water purification function with regard to heavy metals lead, nickel, cadmium, chromium, copper and and zinc aswell as the nutrient phosphorous. The study has also shown that the system is in need of dredging.

    Fysisk aktivitet, rörelserädsla och livskvalitet hos individer som genomgått hjärtinfarkt och/eller hjärtoperation2017Independent thesis Basic level (degree of Bachelor), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Bakgrund: Hjärt -och kärlsjukdom är den vanligaste folksjukdomen i Sverige. Fler män än kvinnor drabbas och c:a 20% av de som drabbats lider utav rörelserädsla. Fysisk aktivitet är en viktig del i primär- och sekundärprevention. Livskvaliteten kan påverkas negativt efter hjärt-och kärlsjukdom.

    Syfte: Syftet var att studera samband mellan självskattad fysisk aktivitet, självskattad rörelserädsla och självskattad livskvalitet hos individer som drabbats av hjärtinfarkt och/eller genomgått hjärtoperation. Syftet var även att studera om det fanns några könsskillnader avseende rörelserädsla och livskvalitet i denna patientgrupp.

    Metod: Studien var en icke-experimentell kvantitativ tvärsnittsstudie där enkäter lagt grunden till beskrivande, korrelerande och jämförande design.

    Resultat: 29 deltagare medverkade. Totalt 19% av deltagarna led av rörelserädsla. Det förekom ingen skillnad mellan könen i median avseende varken rörelserädsla eller livskvalitet. Korrelationskoefficienten var 0,387 (p = 0,07) mellan fysisk aktivitet och livskvalitet i hela gruppen. Sambandet mellan rörelserädsla och livskvalitet var r = -0,460 (p = 0,03).

    Konklusion: Resultatet stämmer överens med tidigare forskning avseende andelen individer som lider utav rörelserädsla. Inga skillnader påvisades mellan fysisk aktivitet och livskvalitet men ett måttligt negativt samband förelåg mellan rörelserädsla och livskvalitet.

    Elsa Beskows bilderboksmotiv: Konstvetenskapliga bildanalyser av utvalda bilder2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Innehåll/Content: Elsa Beskow was an artist and a writer who for 50 years, from the turn of the 19th century, produced a wide variety of books for children. The books have been read for several generations and are translated into multiple languages, and they are still released and appreciated. This essay is based on literature studies and several different art scientific image analysis on selected paintings from Elsa Beskow picture books. The aim is to investigate how the children and their environments are portrayed in her picture books. The theoretical approach assumes that it is possible to preform image analysis on picture book paintings. In the analysis, Beskow’s contemporary theoretical ideas about children, education and also later feminist theory have been taken into account. The methodical approach is based on different image analysis as formal and style analysis according to Wölfflin, iconographic and iconological analysis according to Panofsky, semiotic analys according to Barthes and feminist image analysis or analysis from a gender perspective. The paintings that are analysed are from Children from the Forest, The Flowers’ Festival, The Children of Hat Cottage, Emily and Daisy and Petter and Lotta’s Christmas. The results of my analysis focused on how the children's environments are portrayed. For the showing, the environments are divided into multiple categories: the physical environment (country and city, exteriors and interiors), the family situation (different family constellations), children's education and schooling including ethics and morals, norms and values, the food situation and realism were set against fantasy. The comparison of the analytical methods provided that the formal and style analysis are appropriate to use on picture book paintings, as well as the description and interpretation of the iconographic analysis. The results demonstrated that iconological and semiotic analysis, respectively, were possible but not optimal. Analysis from a gender perspective was suitable. Lastly, the literature studies gave insight into how much of Elsa Beskow's life is reflected in her books.

    När filologerna refererar: En referensanalys av svenska doktorsavhandlingar i ämnet latin2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This study presents a citation analysis of 20 doctoral dissertations in the subject field of Latin which is part of the broader field of classical philology. The dissertations were all written at Swedish universities and were published during two measurement periods between 1979-2017.

    The aim of the study is to provide a basis for decision-making for librarians who are responsible for collections of books and journals on classical philology at Swedish university libraries.

    The study takes as its starting point and theoretical background a citation analysis made by Gregory A. Crawford and published in an article in 2013. That citation analysis was made with a philological journal as empirical object and found a remarkable stability over time in citation practices by scholars involved in classical philology especially regarding the language, age and type of material cited. With Crawfords results as background this present study finds similar patterns of stability in citation practices in the Swedish dissertations analysed.

    The conclusion of this study is that Swedish university libraries should retain their older books on classical philology as well as continue to develop their collections with books as well as journals written in the English, German, French, and Italian languages.

    This is a two years master´s thesis in Library and Information Science.

    Field Current Control for the Damping of Rotor Oscillations and for the Alternative Start of Synchronous Machines: Further Innovative Applications of Field Current Active Control besides UMP-Compensation2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The possibility to save energy in synchronous machines operation by dismissing d-axis damping bars and surrogating them with active excitation current control in sectored field winding is proved. In particular a way to recover the energy of rotor oscillations during power regulation is shown by means of a studycase generator whereas a self-starting machine is analytically and numerically designed in view of its next construction and test. Principal design requirements and limits for both applications are presented and discussed.

    Förebilder i slöjd: en undersökning om vem som kan ses som förebild i nutida pedagogisk slöjd2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The essay's question is what designers, artisans, craftsmen, people working with sloyd or other people could be seen as role models in educational sloyd in a contemporary context. The method of investigating the issue was a web survey targeted at a selection of groups related to sloyd.

    The most common model among my respondents turned out to be a Swedish man who is a relative. Second and third place came two well-known professional craftsmen; Jögge Surolle Sundqvist and Beth Moen. Respondents describe their role models as creative, curious and generous.

    The lack of known models in sloyd can greatly affect the status and position of the educational sloyd. More focus on highlighting a width of rolemodels in sloyd teaching could open up for improved opportunities to work according to the elementary school's curriculum in sloyd.

    Den sövda patientens värdighet på operationssalen: En kvalitativ observationsstudie2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: To maintain the patient's dignity is important for the theatre nurse, which becomes extra clear when the patient is anesthetized. However, there are few studies with focus on dignity of the anesthetized patient in the operating room.

    Aim: The purpose of this study was to observe how the dignity of the anesthetized patient is utilized in the operating room.

    Method: An ethnographic observational study with a qualitative approach was used. The study was conducted at a university hospital in Sweden. Through a strategic selection, 20 operations were observed for 40 hours.

    Result: The result shows differences in staff involvement depending on operation. For operations requiring more extensive preparation, a clearer intention to do the best for the patient was observed. Even the importance of teamwork was observed. The result also showed how the communication between the staff affected the view of the patient and the importance of keeping professionalism in order not to compromise the patient's dignity.

    Conclusion: The dignity of the patient was preserved by the staff. However, there were situations, conversations and actions that showed a violation of the patient's dignity. On occasion, an offense was followed by a preservation by another staff, showing the importance of teamwork in relation to the maintenance of the dignity. The larger and more extensive intervention, the more signs of commitment and care about the patient were observed. This can be explained by the fact that violations of external dignity can be replaced by actions that strengthen internal dignity.

    "As if they're daring you to desire them": En studie av de antika skulpturernas roll i filmen "Call me by your name"2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This Bachelor’s thesis examines the use of ancient bronze statues in the 2017 film Call me by your name by director Luca Guadagnino. Various scenes which feature ancient statues are examined individually using semiotic analysis. The scenes are examined individually, first described on a denotative level, then analyzed on a connotative level. The theoretical stand point is based on the studies of art works in film. Key theoretical concepts used are ”in between-ness” which is a state in which change in narrative is made possible through looking at art, and ”parallels”, a means of which to make art represent the characters in the film. The thesis finds the sculptures in Call me by your name to play a part in affecting the narrative of the film, mainly in regard to the love story between the two lead characters, two men named Elio and Oliver. The acts of looking, examining, and touching the statues in this film help the narrative turn in favor of the lead characters romantic relationship. The thesis argues that the nude bronze sculptures of men from ancient Greece are used in this film as signifiers of desire, timelessness and homoerotic lust.

    En studie kring bronsålderns kulthus och deras kännetecken och landskapskontext2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The design on the bronze age culthouse is very similar to the design of a common house construction from the Bronze Age. In addition to this, there ar very few similarities. Culthouses have not been used for the purpose of the accommodation or other secular context, this results in that the buildings lack the typical settlement finds. The study of the Bronze Age culthouses is an important aspect in the research on the population´s religious beliefs. As archealogists don´t have much knowledges about the Bronze Age religion and its religious beliefs, more research can be executed and a deeper understanding of both the religion and the culthouses can be developed. The culthouses from the Bronze Age that have been examined, show different characters in form of finds and remains. A summary of these findings and remains can create a clearer picture of culthouses and the findings that suggest religios activities.

    De första jordbrukarna och gånggrifterna på Falbygden.: Immigranter eller lokal uppfinningsrikedom, det är frågan?2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay will discuss where the people who built the passage graves and the first farmers at the Falbygden area in Sweden came from. That the first farmers built the passage graves is today a given fact, but how did the Neolithic transition take form in Scandinavia? Two theories have been put forward over the past century, that they learned through cultural diffusion, or that the first farmers were immigrants. Recent DNA- and Strontiumanalyses have been made on skeletons from passage graves from Falbygden and on skeletons from different regions across Europe, both from Mesolithic and Neolithic people. These results show that the Mesolithic hunter-gatherers shares no or little continuity with the Neolithic farmers, even in cases where the two groups lived in close neighbouring for a long time.

    Det filmiska ögat: En undersökning av konstbetraktandets natur i tunnelbanan genom fotomontaget ”Den dagen, den sorgen” på Karlaplans station2018Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen undersöker konstbetraktandets natur i tunnelbanan genom en närstudie av fotomontaget ”Den dagen, den sorgen på Karlaplans tunnelbanestation i Stockholm.  Uppsatsens huvudsakliga frågeställning är: Hur spelar ”Den dagen den sorgen” upp sin mening och hur tas denna emot av betraktaren i tunnelbanekontexten vid Karlaplan? 

     Två underfrågor kompletterar frågeställningen:

    1.Vilken är fotomontagets konstnärliga särart och hur är det organiserat narrativt?

    2.Hur är tunnelbanans ”genius loci” och hur samverkar konstverket med platsen och rummet? 

     

    Impetus för uppsatsen är konstverkets säregna och unika karaktär som konstverk. Det finns inget liknande verk i Stockholms tunnelbana. Det lockar, väcker frågor och involverar betraktaren på ett direkt sätt. Syftet med uppsatsen är därför att undersöka mekanismerna för denna betraktaraktiverande rörelse. En fråga som ofta saknas i den omfattande litteraturen om konsten i Stockholms tunnelbana är hur tunnelbanekonsten kommunicerar och tas emot av sina betraktarresenärer. Denna brist motiverar en undersökning av relationen mellan konstverk, betraktare och miljö.

         Uppsatsen är utförd med hjälp av en deduktiv och systematiskt tolkande arbetsmetod utifrån en receptionsteoretisk och semiotisk teoribildning. De valda frågeställningarna har riktat analysen och fotomontaget har studerats som konstnärligt och språkligt fenomen. Receptionsteorin utgår från Wolfgang Kemps begreppsanalys, vilken är strukturerad i interna och externa faktorer. Peter Gillgren kompletterar Kemp och visar hur betydelsefulla verkets interartiella referenser och den litterära meningen är för den receptionsteoretiska tolkningen. Roland Barthes semiotiska teckenanalys, där denoterande tecken omvandlas till konoterande i betraktarens medvetande, ligger också till grund för tolkningen

         Texten är uppbyggd av fem delar. De består av inledning, bakgrund, interna faktorer, externa faktorer samt avslutande diskussion med slutsatser och sammanfattning. Genom verkets många interartiella referenser framträder en samhällskritisk litterär mening. För att förmedla denna litterära mening har upphovsmannen medvetet sökt motverka en riskerad polysemi. Kompletterande performativa textremsor, det hyperrealistiska fotografiska bildmediet samt en återhållsamhet med fragment stramar åt och riktar bildens ”betydelse”. Bildens komposition och perspektiv samt en frekvent användning av vakanser och fokaliserande gestalter bjuder in betraktaren i bildens ”spel” och sätter dennes öga i rörelse.  Verk, betraktare och miljö möts och förstår varandra i hastiga filmiska ögonblick. Sådan är konstbetraktandets natur på Karlaplans tunnelbanestation.

    Linnelinjen och den moderna handduken2018Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    This thesis focuses on a group of towels from the textile design program Linnelinjen (''the Linen-line'') from 1955. Linnelinjen was a collaboration between the department store Nordiska Kompaniet and the textile manufacturer Almedahl-Dalsjöfors. The first collection, renowned as a modern version of the traditional stock of linen, was created by textile designers Astrid Sampe and Marianne Nilson.

    The thesis is divided into three main parts. Firstly, through archive studies, the towel collection of Linnelinjen 1955 is mapped and described. This basic research throws new light on Linnelinjen, by emphasizing less known products in the collection. Secondly, the towel design is analysed to reveal in what aspects it can be considered modern. Through this analysis, the modern traits of the towel design are found to be connected to the towels' transformation from anonymous household articles to unique design products. Finally, the symbolic function of the towels in the modern home and household is analysed. The line of argument in this last part is based on the concept of myth, as used in the design theory of Adrian Forty. It illustrates how the modern Linnelinjen towels, thanks to their specific field of application, may reconcile the vision of the home as a haven of rest with the conflicting reality of household work.

    Allegori och antikreception: En ikonografisk analys av nischskulpturerna på Stockholms slotts södra entréparti2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper investigates the iconographical meaning of the niche sculptures at the south entrance of the Royal Palace in Stockholm. Two groups of four sculptures have been investigated. The first group of sculptures with motifs of Hercules great victories is illustrated in Nicodemus Tessin the younger’s layout of the south entrance of the Royal Palace in Stockholm from the begin­ning of the 18th century in honour of Carl XII. These sculptures were never made and the niches stood empty until the 1890s when they were filled with the second group of four sculp­tures with motifs of abductions of women from classical mythology that were first made to be in Carl XI’s gallery inside the palace. Due to the debate in 2017’s #metoo-movement the paper dis­cus­ses the Abduction group’s location on the southern entrance and the meaning of them to­day in their new context. The analysis found that Tessin in the Hercules sculptures wanted to show Carl XII as the hero who protects the realm from evil in different forms, which are often repre­sen­ted by symbols of barbarism and wildness. In the Abduction group, Tessin wanted to highlight Carl XI as an absolute ruler.

    Optimering av takttidtabell för järnvägstrafik på en regional nivå: En fallstudie av fyra Mälarstäder2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Effective commuting is an important part of regional development and attractiveness, where railway traffic is a favourable mode of transportation owing to it being energy efficient and environmentally friendly. Attaining more people to choose the train to commute is therefore desirable. A concept aiming to increase the use of railway traffic is cyclic timetable. At present the concept is most frequently used on a national level but there are possibilities to implement the ideas on a more regional level.

    The purpose of this thesis is to study if and how a cyclic timetable for railway traffic can be constructed and optimised for a region, more specifically the region “Fyra Mälarstäder”. Challenges and opportunities to implement this type of timetable on a regional level are also discussed.

    In order to construct a timetable for railway traffic several infrastructural limitations must be taken into account. An example that extensively limits railway capacity is single tracks. Hence, to be able to construct and optimise the timetable these limitations were formulated, together with a number of other criteria, mathematically as constraints for an optimisation problem. For the optimisation setup the objective function consisted of a sum of weighted trip times within the system, which in turn was minimised.

    Results conclude that a cyclic timetable could successfully be used for “Fyra Mälarstäder”. However, some aspects remain to be investigated, including train line continuation beyond the system boundaries of the study. As for the optimisation, it appears that the weighting of the objective function plays a considerable role to obtain a satisfying timetable. Varying and adjusting certain parameters may also be favourable to achieve a timetable as beneficial as possible.

    Påverkan på spänningskvalité av enfasiga solcellsanläggningar i Gävle Energis lågspänningsnät2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In recent years, the number of photovoltaic systems (PV systems) has increased in Sweden. According to the Swedish Energy Agency the number is expected to continue to increase in the future, much thanks to the declining prices of PV systems. The government´s goal of 100% renewable electricity generation in 2040 can be achieved if half of all small houses in Sweden install PV systems.The 31st of December 2017, Gävle Energi had 39 PV systems whereof 16 had installed capacity of less than 5kW, corresponding to 0,16% of the Swedish PV installations of less than 5kW.

    In this report a study of how the voltage quality is affected by installation of an increased number of single phase PV systems is presented. The study is performed on 4 different rural area distribution grids and the voltage is analysed with respect to the following quality criteria’s:

    • Voltage change in connection point, max 5%

    • Voltage change in interconnection point, max 3%

    • Voltage variation, ±10% of nominal value (207-253V)

    2 different scenarios have been considered for each area:

    • ”The two houses with largest impedances have PV systems”

    • ”50% of the houses in one area have PV systems”

    The simulations performed in this study show that the voltage exceeds one or more of the electrical quality requirements listed above for all four of the studied areas. Measures such as cable reinforcement in connection points and/or interconnection points is recommended.

    Rigid barrier or not?: Machine Learning for classifying Traffic Control Plans using geographical data2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this thesis, four different Machine Learning models and algorithms have been evaluated in the work of classifying Traffic Control Plans in the City of Helsingborg. Before a roadwork can start, a Traffic Control Plan must be created and submitted to the Traffic unit in the city. The plan consists of information regarding the roadwork and how the work can be performed in a safe manner, concerning both road workers and car drivers, pedestrians and cyclists that pass by. In order to know what safety barriers are needed both the Swedish Association of Local Authorities and Regions (SALAR) and the Swedish Transport Administration (STA) have made a classification of roads to guide contractors and traffic technicians what safety barriers are suitable to provide a safe workplace. The road classifications are built upon two rules; the amount of traffic and the speed limit of the road. Thus real-world problems have shown that these classifications are not applicable to every single case. Therefore, each roadwork must be judged and evaluated from its specific attributes.

    By creating and training a Machine Learning model that is able to determine if a rigid safety barrier is needed or not a classification can be made based on historical data. In this thesis, the performance of several Machine Learning models and datasets are presented when Traffic Control Plans are classified. The algorithms used for the classification task were Random Forest, AdaBoost, K-Nearest Neighbour and Artificial Neural Network. In order to know what attributes to include in the dataset, participant observations in combination with interviews were held with a traffic technician at the City of Helsingborg. The datasets used for training the algorithms were primarily based on geographical data but information regarding the roadwork and period of time were also included in the dataset. The results of this study indicated that it was preferred to include road attribute information in the dataset. It was also discovered that the classification accuracy was higher if the attribute values of the geographical data were continuous instead of categorical. In the results it was revealed that the AdaBoost algorithm had the highest performance, even though the difference in performance was not that big compared to the other algorithms.

    Museets moderna postmoderna digitalisering: Hur digitaliseringen av museers kulturarv uppfattas och varför2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This study is a critical analysis of the various opinions of why museums should digitize their heritage collections. The aim of the study is to break these opinions down and critically analyse them in order to increase our understanding of why digitization is a desirable activity in museums. The purpose is to contribute to sustainable digitization works in the future.

    The opinions analysed in this study have been identified from three main sources: previous research; official policies and guidelines; and through interviews with the staff at Nationalmuseum in Stockholm, Sweden.  An argument analysis was conducted to identify the main positive and negative opinions of digitization. A theoretical perspective based on the societal development from modernity to postmodernity was incorporated into the analysis to uncover why these particular opinions exist.

    The study shows that while several issues with digitizing the cultural heritage of museums were acknowledged, the attitude towards digitization was predominantly positive. The negative opinions and fears of digitization, such as the potential loss of the physical experience turned out to be either unwarranted or solvable. The positive effects of digitization, such as increased accessibility, outweighed the negative issues. The opinions found in the previous research and the official policies reflected those of the staff who had been working with digitization in recent years at Nationalmuseum.

    Analysing the opinions showed that digitization is essentially a postmodern activity that caters to the needs and aims of the postmodern society. The reason why museums, that are traditionally modern would resort to a postmodern activity such as digitization is because digitization does not in fact undermine the authority of the museum, but rather helps this institution to fulfil its role and stay relevant in a postmodern society.

    This study is a two-year master’s thesis in Museum and Cultural Heritage Studies.

    Den 'goda' sexualitetens villkor: En diskursanalys av sexualitetframställningen i undervisningsmaterial i sex och samlevnad 1956-20132018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Sweden has a long tradition of having sex education in primary school and some of the teaching material have earned international spread. In Sweden, the state develops the teaching material on sex education, such as curriculums and guidelines. In the current essay, school is regarded as an extension of the state. Therefore the state’s view on sex education should be reflected in the teaching material and have impact on the socialization of Swedish adolescents. The research question addressed in this essay concerns the notion and portrayal of the 'ideal' sexuality in four state-developed teaching material on sex education between 1956 and 2013 and how it has altered since sex education became mandatory in 1955. In order to answer this, a Foucauldian discourse analysis is applied as both a theory and method complemented by Rubin's theory about "the sloping walls". The result shows that the 'ideal' sexuality in 1956 is a societal matter and abstinent. In 1977 the 'ideal' sexuality is "free but with responsibility" and exercised on equal terms. In 1995, the 'ideal' sexuality is intertwined with love, an individual right and a source of happiness, and heteronormativity is prominent up until now. Lastly, in 2013, the 'ideal' sexuality is norm-critical and an individual matter. Initially, the state was clear about what the 'ideal' sexuality included. The most prominent discursive change found was that the state over time embodies an unobtrusive role, illustrated by silences and ambivalence in the teaching material from 2013. Further research on implementation is required in order to investigate what adolescents internalize of the messages conveyed in the current sex education teaching material and how it affects the self-perceived sexuality. Our hope is that the study motivates the transformation of sex education as an independent school subject and part of the Swedish teacher education.

    Individualisering av samhällskunskapsundervisningen: En kvalitativ studie om samhällskunskapslärares upplevelser av individualiseringen av samhällskunskapsundervisningen2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Individualiseringen i den svenska skolan blir allt mer central i hur undervisningen ska utformas. Varje elev ska enligt dagens läroplaner (Gy11 och Lgr11) få anpassad undervisning utifrån sina egna förutsättningar och behov vilket ställer höga krav på lärarnas yrkeskompetens. Denna uppsats syftar därför till att undersöka hur samhällskunskapslärare upplever och reflekterar kring individualiseringen i skolundervisningen samt få en förståelse för hur de praktiskt går tillväga för att individualisera undervisningen. Detta studerades med hjälp av kvalitativa intervjuer med samhällskunskapslärare från både högstadiet och gymnasiet. Utifrån intervjuerna och resultatet från studien kan man sammanfattningsvis se att samhällskunskapslärarna från denna studie är positivt inställda till individualiseringen av undervisningen och att de generellt sett använder sig av allmänna metoder för att individualisera undervisningen. Det verkar inte heller finnas en enskild universallösning för hur man individualiserar undervisningen efter olika elevers förutsättningar och behov vilket gör det intressant att analysera och jämföra de lärarnas olika tillvägagångssätt.

    Frihet utan rättigheter?: En studie om rättslig pluralism i Libanon och hur det påverkar kvinnors rättsliga ställning.2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    With Legal pluralism, a state has more than one legal system in which rights can be attributed to citizens through private or religious actors. Lebanon has established religious family law through the constitutional charter, in which personal status is delegated to the country’s different confessions to govern. Citizens of different confessions are thus assigned different rights which particularly tends to affect the rights of women.

     In this study, the impacts of Lebanon's legal pluralism on the legal status of women is being examined to give an understanding of how the legal system from a gender perspective, and to examine how the outcome affects women’s everyday life by the coexistence of religious and civil courts. The study also examines how Lebanon, with its current constitution, can fulfill the international law obligations stemming follow from the Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW). Through legal methods and semi-structured interviews made with civil society, legal and academic persons in Beirut - the current laws in Lebanon were analyzed based on the concepts of gender, male dominance, and private and public sphere to visualize the relationship of gender and its significance in the Lebanese legal system.

    The results of the study show that legal pluralism in Lebanon can be understood in relation to how the complex history of the country has influenced the formation of the judicial system in which a male norm is dominating. The rights of women have been thrust to the private sphere and a masculine norm permeates the Constitution, family law and civil laws, which creates gender segregation in society. Thus, gender affects the legal status of women and the impacts of legal pluralism affect their daily lives negatively as their legal status is subordinate to men regarding marriage and its dissolution, custody of children, and nationality.

                          Regarding the Conventional right, the study shows that the current constitution allows for space to fulfill CEDAW. Thus, the protection of the Convention is not being fully implemented in neither the personal status related laws or civil laws. However, Lebanon has reservations towards key articles of the Convention which result in that the full potential of the Convention is not maintained.

    Delaktighet och skydd - Två (o)förenliga världar?: En kvalitativ studie om barns möjlighet till delaktighet och skydd i tingsrättsdomar där det förekommit uppgifter om våld2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vid en bedömning av barnets bästa ska domstolen enligt föräldrabalkens 6 kap. 2a§ särskilt fästa avseende vid tre aspekter: barnet har rätt till en god och nära kontakt med båda föräldrar, barnet har rätt till skydd och hänsyn ska tas till barnets egen vilja. I familjerättsliga mål där det förekommit våld ställs möjligheten att förena dessa aspekter på sin spets. Denna kvalitativa dokumentstudie ämnar följaktligen undersöka på vilket sätt barn och vad som är till deras bästa framställs av tingsrätten i vårdnadsmål där det förekommit uppgifter om våld, med fokus på vilken möjlighet till delaktighet och skydd barnen erbjuds. Det empiriska materialet har bestått av tjugo tingsrättsdomar och har analyserats genom en kvalitativ innehållsanalys. För att problematisera barns möjlighet till delaktighet har studien tagit sin teoretiska utgångspunkt i barndomssociologin. Där även Leena Alanens (1992) begrepp familialisering och Lotta Dahlstrands (2004) delaktighetsstege har utgjort viktiga verktyg vid analysen. Studien visar på att barnets behov av en nära och god kontakt med båda föräldrar är mer framträdande i tingsrättens resonemang om barnets bästa än barns behov av skydd. Detta trots att studien behandlar tingsrättsdomar med uppgifter om våld. Vidare menar vi på att barn i flera fall osynliggörs som egna individer med egna åsikter då familjen används som tolkningsram. Föreställningar om att barn är lojala sina föräldrar och kan underlåta att berätta eller ljuga för sina föräldrars skull hindrar tingsrätten från att tillmäta barnens vilja betydelse. Barnens kronologiska ålder tycks även vara knuten till barnens grad av delaktighet i domarna. Små barn under fem år ges ingen röst i domarna medan äldre barn i tonåren i flera fall får fullt gehör för sin vilja.

    Ledares agerande i kunskapsutbytande grupper2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Effectiveness and performance in groups are largely dependent on how group members manage to share their individual knowledge with each other. When group members share and combine their individual knowledge at an optimal level in order to find new solutions, they achieve knowledge integration. In this thesis, we examine how group leaders act to encourage knowledge integration. An observational study was used to evaluate how leaders in three different groups act when solving a group task. We focused on the leaders’ actions in relation to group behaviours that would promote and prevent knowledge integration. With support from theories, we created a behaviour model to help us identify a set of relevant behaviours. We also supported our analysis with leadership theories. The results showed us that leaders’ actions were to a great extent dependent on the current followership and dynamics of each group. Another result was that group members who were familiar with one another before entering the group, had more difficulties in adopting behaviours that would promote knowledge integration. This meant that the leader did not come to terms with the leadership in order to promote knowledge integration.

    Samverkan i form av SSPF: Är det rätt väg att gå?2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I vår studie har vi undersökt hur samverkan inom verksamheten SSPF (samverkan mellan skola, socialtjänst, polis och fritid) i Uppsala kommun fungerar enligt aktörerna. Vi avsåg att undersöka aktörernas uppfattning av hur samverkan fungerar och ifall uppfattningen skiljde sig mellan de olika yrkesgrupperna. Fokus för uppsatsen var således inte att mäta effekterna av insatser som utförts via SSPF:s verksamhet. Studien har utgått från tidigare forskning om lyckad samverkan genom engagemang, lyhördhet, tillgänglighet och tillit, samt omständigheter som utgör hinder för samverkan såsom; bristande samsyn, oförståelse för andra aktörers uppdrag och skiljande regleringar. Detta, tillsammans med vårt teoretiska ramverk, gav en övergripande bild av forskningsfältet och verkade som underlag för analys och diskussion kring resultatet. Det teoretiska ramverket bestod av begrepp som gräsrotsbyråkrati, roller och handlingsutrymme som alla kopplas samman till begreppet samverkan. Det empiriska materialet bestod av data från vår genomförda enkätstudie om SSPF–samverkan i Uppsala kommun. Till den jämförande analysen genomfördes Chi 2 – tester. Utifrån resultatet kunde vi utläsa att aktörerna inom SSPF ansåg att samverkan hade bidragit till nytta i störst utsträckning i form av "Informationsutbyte", "Helhetssynen på ungdomar i riskfyllda situationer" och "Kontaktvägar".  De förhållanden som aktörerna ansåg utgjorde hinder för SSPF-samverkan i störst utsträckning var "Bristande ekonomiska resurser", ""Krockande" lagstiftning och regelverk" och "Bristande personalresurser". Mellan yrkesgrupperna skola, socialtjänst och fritid förekom signifikanta skillnader för variabeln ""Krockande" lagstiftning eller regelverk” som hinder för SSPF-samverkan. För yrkesgrupperna skola och fritid fanns signifikanta skillnader för variablerna ”Bristande personalresurser” som hinder och ”Kontaktvägar” som nytta. Slutligen påvisades även signifikanta värden mellan yrkesgrupperna socialtjänst och fritid gällande ”Bristande/oklart beslutsmandat”.
