    Trådlöst elektriskt lås2007Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med examensarbetet är att göra en trådlös version av det elektriska lås som tillverkas av Electec System AB.

    För att göra ett trådlöst elektriskt lås måste ett batteri monteras i låset. Batteriet måste hållas uppladdat hela tiden för att kunna driva motorn och ge strömförsörjning till elektroniken i låset. Alla signaler mellan låset och styrenheten ska dessutom överföras trådlöst istället för med kabel. Signalerna måste kodas innan sändning så att ingen obehörig kan läsa signalen och sedan öppna dörren.

    Det svåraste i ett trådlöst elektriskt lås är att överföra effekt från dörrkarmen till låset eftersom utrymmet är begränsat och avståndet mellan låsblecket i karmen och låset i dörren kan uppgå till 10 mm. För att överföra effekt från dörrkarmen till låset konstruerades en transformator. Förlusterna i transformatorn ökar kraftigt då luftgapet ökas.

    Det visar sig att motor och övriga kretsar kan drivas med ett avstånd mellan kärnorna på upp till 7 mm. Luftgapet kan sannolikt ökas när andra transformatorkärnor används. Dessa fanns dock inte tillgängliga under examensarbetets gång på grund av lång leveranstid. I jämförelse med överföring av effekt är problemet att koda och överföra signaler mellan styrenheten och låset enklare och kan lösas med hjälp av färdiga kretsar.

    Satisfactory reliability among nursing students using the instrument PVC ASSESS to evaluate management of peripheral venous catheters2014In: Journal of Vascular Access, ISSN 1129-7298, E-ISSN 1724-6032, Vol. 15, no 2, p. 128-134Article in journal (Refereed)
    Abstract [en]

    Purpose: Nursing students should be given opportunities to participate in clinical audits during their education. However, audit tools are seldom tested for reliability among nursing students. The aim of this study was to present reliability among nursing students using the instrument PVC assess to assess management of peripheral venous catheters (PVCs) and PVC-related signs of thrombophlebitis. Methods: PVC assess was used to assess 67 inserted PVCs in 60 patients at ten wards at a university hospital. One group of nursing students (n= 4) assessed PVCs at the bedside (inter-rater reliability) and photographs of these PVCs were taken. Another group of students (n= 3) assessed the PVCs in the photographs after 4 weeks (test-retest reliability). To determine reliability, proportion of agreement [P(A)] and Cohen's kappa coefficient (k) were calculated. Results: For bedside assessment of PVCs, P(A) ranged from good to excellent (0.80-1.0) in 55% of the 26 PVC assess items that were tested. P(A) was poor (< 0.70) for two items: "adherence of inner dressing to the skin" and " PVC location." In 81% of the items, k was between moderate and almost perfect: moderate (n= 5), substantial (n= 3), almost perfect (n= 5). For edema at insertion site and two items on PVC dressing, k was fair (0.21-0.40). Regarding test-retest reliability, P(A) varied between good and excellent (0.81-1) in 85%-95% of the items, and the k ranged between moderate and almost perfect (0.41-1) in 90%-95%. Conclusions: PVC assess demonstrated satisfactory reliability among nursing students. However, students need training in how to use the instrument before assessing PVCs.

    A new reliable tool (PVC assess) for assessment of peripheral venous catheters2010In: Journal of Evaluation In Clinical Practice, ISSN 1356-1294, E-ISSN 1365-2753, Vol. 16, no 6, p. 1108-1115Article in journal (Refereed)
    Abstract [en]

    Rationale and aims To evaluate the extensive use of peripheral venous catheters (PVCs), including catheter-related complications, a reliable tool for PVC assessment is needed. The aim of this study was to develop such a tool to evaluate PVCs in relation to management, documentation and signs and symptoms of thrombophlebitis (TH), as well as to determine its inter-rater and test-retest reliability. Method The tool development included confirmation of content and face validity. Two groups of registered nurses used the new tool (PVC assess) to assess PVC management and signs of TH independently. Group A (n = 3) assessed 26 items in 67 PVCs bedside (inter-rater reliability). Group B (n = 3) assessed photographs (67 PVCs, 21 items) of the same PVCs as those in Group A with a 4-week interval (test-retest reliability). Proportion of agreement P(A) and Cohen's kappa were calculated to evaluate inter-rater and test-retest reliability. Results Among nurses assessing PVCs at bedside, the P(A) was good to excellent (0.80-1) in 96% of the items in PVC assess. In 80% of the items kappa was substantial to almost perfect (0.61-1). TH sign erythema fell into the fair range (kappa = 0.40). In test-retest reliability analysis the P(A) was within the good and excellent range (0.80-1.0) and kappa varied from moderate to almost perfect (0.41-1.0) in 95% of the items. One item 'outer dressing is clean' was in fair range (0.21-0.40). Conclusions The PVC assess instrument shows satisfactory inter-rater and test-retest reliability. Reliability tests on reviewing documentation remain to be performed.

    Handling of peripheral intravenous cannulae: effects of evidence-based clinical guidelines2006In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 15, no 11, p. 1354-1361Article in journal (Refereed)
    Abstract [en]

    Aim. This study aimed at evaluating the outcome of implemented evidence-based clinical guidelines by means of surveying the frequency of thrombophlebitis, nurses’ care, handling and documentation of peripheral intravenous cannulae. Background. Peripheral intravenous cannulae are frequently used for vascular access and, thereby, the patients will be exposed to local and systemic infectious complications. Evidence-based knowledge of how to prevent these complications and how to care for patients with peripheral intravenous cannula is therefore of great importance. Deficient care, handling and documentation of peripheral intravenous cannulae have previously been reported. Design. A cross-sectional survey was conducted by a group of nurses at three wards at a university hospital before and after the implementation of the evidence-based guidelines. Method. A structured observation protocol was used to review the frequency of thrombophlebitis, the nurses’ care, handling and the documentation of peripheral intravenous cannulae in the patient's record. Results. A total of 107 and 99 cannulae respectively were observed before and after the implementation of the guidelines. The frequency of peripheral intravenous cannulae without signs of thrombophlebitis increased by 21% ( P < 0·01) and the use of cannula size 0·8 mm increased by 22% ( P < 0·001). Nurses’ documentation of peripheral intravenous cannula improved significantly ( P < 0·001). Conclusion. We conclude that implementation of the guidelines resulted in significant improvements by means of decreased frequency of signs of thrombophlebitis, increased application of smaller cannula size (0·8 mm), as well as of the nurses’ documentation in the patient's record. Relevance to clinical practice. Further efforts to ameliorate care and handling of peripheral intravenous cannulae are needed. This can be done by means of increasing nurses’ knowledge and recurrent quality reviews. Well-informed patients can also be more involved in the care than is common today.

    Att sova med fienden: - Om väljarstöd, blockidentifikation och blocköverskridande styren2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Minority- and cross-bloc regimes in Swedish municipalities have more than doubled the last ten years. The phenomenon should be seen in light of the fact that the traditional blocks have lost support in favor of new parties in the municipal parliaments, such as the Swedish Democrats and different local parties. Historically, the municipal political arena is usually described as less ideological than the national arena. Nevertheless, in the 2014 elections, the turnout resulted in formations of weak center-right/center-left minority governments in one third of the muncipalities in Sweden. When municipal elections result in hung parliaments, remarkably many parties seems to favor minority governments instead of establishing cross-bloc majorities. Why? A possible explanation is that the party identification among the swedish electorate has been replaced by a strong bloc identification, which might induce the parties to avoid coalitions that jeopardize the support from bloc identificated voters. But is this fear rational? Do political parties that form cross-bloc coalitions lose more electoral support than parties that form bloc coalitions?

       Thus, the purpose of this study is to provide new knowledge about the Swedish electorate and the impact of bloc identification on Swedish politics, by investigating whether coalition parties election results are related to the choice between bloc and cross-bloc coalitions. This is done by statistical Mann-Whitney tests of election data from Swedish municipal elections between 1994-2014.

       The study shows that the average voter support does not differ significantly for parties in blocs compared to parties in cross-bloc coalitions. The exception is the Social Democratic Party, which on average loses fewer votes in cross-bloc coalitions compared to scenarios in which the party is ruling alone or in a traditional bloc. With these results, the study complement previous research on bloc identification and electoral behavior. Furthermore, the study does not support the hypothesis that a party's electoral support in cross-bloc coalitions differs, depending on whether or not the party is leading the cross-bloc coalition.

       In summary, the study does not provide rational support for non-scientific assumptions that cross-bloc coalitions are associated with particular declining electoral support, despite increasing political mobility and enhanced block identification among the electorate.

    Besvär!: Om motståndet hos två tvångssammanslagna kommuner i samband med kommunblocksreformen2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    The purpose of this essay is to investigate why the two Swedish municipalities of Frykerud and Östmark were the only municipalities in Värmland that were forcibly merged by the state during the ”Municipality block reform” of 1971, and whether local identities played a role in the resistance against this reform. 

        The study is designed as a comparative case study and builds on both history and political science to analyze the topic from a broader perspective. Based on the research situation three theoretical theses have been formulated, the durability of which will be tested in the analysis part of the essay.

        The study notes that Frykeruds resistance against the ”Municipality block reform” started when the reform prevented a planned retirement home construction in the municipality. In the analytical part of the essay, the author discusses how the discontent can be interpreted as symptomatic of bourgeois centralization resistance, as well as being due to the fact that traditional, local self-government as a political subject was perceived as threatened. In Östmark, the "Municipality block reform" developed into a political struggle between the reformist Social Democrats and the "reform-skeptical" conservative parties. The battle started with disagreements over the completions of investments in the municipality.

        In the analysis section, the hypotheses previously formulated have been tested, and the author also formulates a new hypothesis regarding the local communities and local identities' political role in the resistance against the "Municipality block reform".

    Den lyssnande kommunen: Om medborgardialog ur förtroendevaldas, tjänstemäns och medborgares perspektiv2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    For the last decades, the party memberships in Sweden have decreased from 600.000 to 300.000, although the general interest in politics have been stable during the same period. This situation can be percieved as a threat to swedish democracy; if the political parties are loosing contact with the citizens, the parties will also face the risk of not being able to canalize the views of the citizens. If that’s the case, the represenative democracy might loose legitimacy. These conclusions have triggered local municipalities in Sweden to launch ”civil dialogue”, innovative ways to include the citizens in public projects and welfare services, with the purpose to re-establish connection and trust between the public and civil sector. However, political studies suggest that civil dialogue rarely have succeeded to strenghtened democracy. In some cases, civil dialogue seemed to hurt trust and legitimacy in local municipalities. That makes the civil dialogue phenomenon interesting – how can attempts to reinforce trust and democracy result in a backfire? What in the core of civil dialogue might catalyze this backlash?

       The nature of civil dialogue suggest that cooperation between the public and civil sphere is becoming more acceptable, even desirable, in swedish politics. This development breaks with the traditional ways of public administration and bureaucracy in Sweden. However, the cooperation between the public and civil sphere is also the core of a new broad trend in public administration and governing, namely ”governace”. Governance refers to a way of adminstrating public affairs by the logic of networks, including the civil society in the public affairs with the purpose of making the public administration more effective and to find creative solutions on new problems. The first aim of this study is to recieve a new understanding how the subjective experiences of civil dialogue participants can affect legitimacy and trust, by analyzing the experiences of participants in a failed dialogue. The second aim is to explore wether civil dialogue is better understood as a part of a new broad trend in public buraucracy, governance, rather than more traditional bureaucracy. These aims are fulfilled using a case study, which has a swedish local municipality, Sunne, in focus.

       The results of the study suggests that none of the participants of the civil dialogue in Sunne experienced that they had ”been listened to”, which seems to be an important cause behind the negative result of the specific dialogue. The innovativeand failed attempt to strengthen the legitimacy of local democracy resulted in a negative reaction through the traditional channels of political participation. The study also suggests that civil dialogue and governace have some similarities regarding their main principles of value and general logic, but since the municipality of Sunne didn’t implement the steering logics of civil dialogue in its full practice, it’s hard to judge wether it should be perceived as governance or not.

    Håll gränsen!: Centerpartiets försvarspolitik 1912-20152016Student paper second term, 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to describe the Swedish Centre Party’s defense policy between the years 1912-2015. and try to outline potential ideological changes in their politics during the same period. An ideology analysis is employed for the purpose.

    The analysis is carried out by a method based on ideological ideal types, to which the Swedish Centre Party’s defense policy through history are compared to. The ideological ideal types ”liberalism” and ”realism” are aiming to describe the international defense policy, whilst the ideal types ”doves” and ”hawks” are aiming to describe the national defense policy. The use of ideal types, as it is done in this study, is to be seen as a way to bridge the gap between everyday policies and more abstract ideology.

    The result of this study shows that not only has an ideological change taken place in the Swedish Centre Party’s defense policy during the course of history; three major changes are identified and described. The study also shows that the Swedish Centre Party has made an ideological travel from being isolationistic pacifists pre-World War I to approaching a more liberal hawk-influenced defense policy in the 21th Century.

    Demokrati i förskolan: En kvalitativ studie om pedagogers arbetssätt och syn på barns inflytande2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of my study is to identify which approach that the teachers believe that they use in their work with children's influence. The aim is also to investigate whether or not the teachers experience any consequences when giving the children a chance to influence and if so, what kind of consequences.

    I have used qualitative interviews to answer the questions of my thesis. My conclusion, based on the result of the interviews, indicates that teachers believe children experience limited influence in routine situations. The results also indicates that teachers who demonstrates a conscious democratic approach while teaching, believed they helped children get a better understanding of the concept of democracy already at an early age.

    Perspektiv på läsning: En högstadielärare och sex av hans elever om skönlitteratur i svenskämnet2006Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    This essay is about literature instruction in the last three years of Sweden’s compulsory school from one teacher’s and six of his pupils’ perspective. The research is analysed from a socio-cultural perspective on learning and literature reception.

    The empiric material is based on interviews with the teacher and six of his students.

    The research shows that there is a difference between what the pupils read on their spare time and what they read during Swedish instruction. It also shows that the pupils wants literature full of action where descriptions of people and the setting don’t slow down the reading experience.

    The teacher is successful in finding literature the pupils appreciate but sees the value of literature on another level – in the processing of the reading experience. He gives his pupils the task to discuss their views on the text’s meaning based on their specific expe-rience. The instruction is thereby partly in co-ordnance with ideals put forward by literature instruction theorists Louise M. Rosenblatt and Judith A. Langer. The dialogic and socio-cultural perspective on learning which Lev S. Vygotskij proclaims is also an inspiration for the teacher.

    Arbetstagarnas inställning till arbetsgivaren gällande lojalitet och tillit: en jämförande studie2006Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    I denna studie har en jämförande studie mellan privat och offentlig sektor genomförts gällande arbetstagarens inställning till sin arbetsgivare. Studien bygger på en hypotetiskt deduktiv metod i vilken vi försöker verifiera vår hypotes. Hypotesen är att arbetstagare inom privat sektor känner större tillit och lojalitet till sin arbetsgivare. Vidare avser vi att studera hur arbetstagarnas inställning till sin arbetsgivare påverkas av de grundläggande tillits- och lojalitetsfaktorerna. De faktorer som ingår i undersökningen är ledningens hänsyn, kompetens, ärlighet och öppenhet, belöningssystem samt ledningens förmåga att inte svika sina arbetstagare. Hypotesen prövas sedan mot de analyser som görs utifrån empiriska data. I undersökningen ingick 168 respondenter från ett flertal olika arbetsplatser. Av dessa var 76 stycken anställda inom privat sektor och 92 stycken inom offentlig sektor.

    Resultatet visar att arbetstagare inom den privata sektorn har en mer positiv inställning till att ställa upp för sin arbetsgivare. Att de offentligt anställda har en mer negativ inställning är en tendens som samtliga redovisade påståenden verifierar. Gällande delen av analysen som specifikt behandlar de tillits- och lojalitetsgrundande faktorerna visar resultatet att arbetstagare inom privat sektor i större utsträckning anser att deras arbetsgivare hanterar faktorerna på ett bra sätt. Ett resultat av detta är arbetstagarnas beteende, vilket skiljer sig åt i de två sektorerna. De privat anställda ställer i större grad upp för sin arbetsgivare exempelvis när det gäller övertidsarbete samt att de ger en mer positiv bild av sin arbetsgivare till personer utanför organisationen. Sammanfattningsvis konstaterar vi att vår hypotes verifieras, det vill säga arbetstagarna inom den privata sektor har en mer lojal inställning till sin arbetsgivare än vad arbetstagarna inom den offentliga sektorn har.

    Åtgärdsprogram i nya skollagen: Några lärares och rektorers erfarenheter, förväntningar och tankar2012Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis is to find out if principals and teachers have experience, expectations and thoughts about the differences that the new Education Act means in relation to the old one about action programme. Through qualitative interviews with two principals and four teachers, I have tried to answer my research questions that I have made based on the purpose. The questions are: How do the interviewees describe the routines about action programme?  Has, according to the interviewees, the routines been changed with the new Education Act? How do teachers and principals experience the differences between the old and new Education Act regarding the action programmes?

    The results of my survey shows that the process of action programme is different at different schools and that it has been adapted to the new Education Act in varying degrees. These results give differences in the experiences of the new directives. Differences between principals and teachers also become visible, which may be due to that the interviewed principals seem to know more about what’s included in the new Education Act than the interviewed teachers. Conclusions to be made from the survey is for example that it is important for schools to review their routines regarding action programme, even if they already have been developed to be similar to the new directives. This is important to ensure that the process is done correctly. It is also important to ensure that all staff understands the new directive and its purpose.

    Key words: Action programme, the new Education Act, principal, teacher, teacher for special needs education, special support.

    Beteende eller sinnessjukdom?: Psykiatri och behandling vid Mariebergs sjukhus mellan 1930-19502015Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper is interested in Swedish psychiatry during the period between 1930-1950,localized to Mariebergs hospital in Sweden. The purpose of this paper has been to testSjöstroms evidence of the pattern that he used to create three analytical concepts, roughlytranslated to; morally educative discipline-treatment, the production process and the idealinstitution citizen. Sjöström motivates that his concepts gives insight into one aspect of thepsychiatric expansion between 1860-1960 as well as creates an understanding of psychiatryas an institution. The source material for this paper has been patients' medical notes writtenby the chief physician of the institution. Via a method which mainly different from Sjöstromin its selection, categorization and more thorough presentation, this paper has seen the samepatterns which Sjöström has created his three concepts from. The ideal institution citizen,defined by its well behaved and calm behaviour emerges also in this papers quantitativecompilation of qualitative data as the clear majority. The morally educative disciplinetreatment,treatments and punishments that focuses on creating an acceptable behaviourrather than the treatment of insanity itself, can be seen in the adjective behaviouraldescriptions of the type well-behaved / badly-behaved which are dominant. The focus in thejournals is behaviour rather than mental decease symptoms such as hallucinations andtreatment is based on unaccepted behaviour rather than symptoms. Also, the sequential orderthat exists between badly-behaved behaviour and treatments, and well-behaved behaviourand rewards shows the focus on behaviour which the concept is based on. The previous tworesults together is the two parts of Sjöströms production process, that trough the morallyeducative discipline-treatment the institution creates an acceptable, quiet and well behavedideal institution citizen were the mental decease becomes secondary.

    Demokratiteoretisk analys av läromedel i Samhällskunskap: En kvalitativ studie om det demokratiteoretiska innehållet i läromedel för Samhällskunskap 1a1 och 1b under GY-20112013Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This qualitative study is done with the purpose of creating understanding for the theoretical democratic content in educational materials for Civic Education courses 1a1 and 1b during GY-11, so teachers create an intentional approach when using educational materials in their democratic education. This was motivated as important considering the reduction in obligatory Civic Education for the vocational programs. The study was conducted using a hermeneutic qualitative reading method where the educational materials, more specifically two series with one book for each course, was read with purpose of creating understanding for the democratic content according to ideal democratic models: deliberative democracy, participatory democracy and electoral democracy. A text voice analysis was also conducted using Bakhtins theory of dialogic and monologue text that contributed to the general result concerning the democratic content. The results show that the electoral democracy ideal is dominant in all educational materials, there is hence no striking difference between the democratic content in 1a1 and 1b educational materials. Though the study shows intention in the 1a1 educational materials towards a more participatory democracy ideal, the electoral ideal are still clearly dominant.

    Riskhantering i kommuner och landsting: ISO 31000, riskbegreppet och organisationsövergripande riskhantering2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In 2009 the first ISO-standard focused exclusively on risk management was adopted, ISO 31000:2009. It is supposed to be possible to use it in any societal sector. There is currently little information on how widely the standard has been used, regarding both public and private sector. The study at hand aims to collect information on how it is used in Swedish municipalities and county councils (i.e. local and regional level).  Furthermore, it aims to study how these actors’ risk management relates to some certain aspects of the standard. These are how risk is defined and enterprise risk management.

    A survey has been conducted. All county councils and 48 municipalities were contacted. Sampling regarding municipalities was made by using a categorization made by the Swedish Association of Local Authorities and Regions combined with random choices.

    The results of the study reveal that the use of ISO 31000 is very limited. It is used by two municipalities and not one of the county councils. Some of the latter are however considering using it.  It seems to be the ambition of both municipalities and county councils to apply enterprise risk management in a way that is principally in line with ISO 31000.  

    Furthermore, the results show that municipalities and county councils define risk in different ways. The majority of these organizations say that they use a defined definition of risk in the whole organization. Approximately half of the municipalities use the definition of risk being used by the Swedish Civil Contingencies Agency, i.e. risk is the product of probability * consequence. Amongst county councils only a quarter use this definition. To a larger extent they use definitions that take into account the objectives of their organizations.

    It is hard to judge which consequences this might have. It might be good to know though, e.g. when future governmental controls are being developed.

    The results also show that there are differences between municipalities and county councils when it comes to enterprise risk management, where the latter use it more extensively. There is a gap however between how much enterprise risk management is used and how much municipalities and county councils would like to use it.

    Illness as unhomelike being-in-the-world?: Phenomenology and medical practice2011In: Medicine, Health care and Philosophy, ISSN 1386-7423, E-ISSN 1572-8633, Vol. 14, no 3, p. 323-331Article in journal (Refereed)
    Abstract [en]

    Scientific medicine has been successful by ways of an ever more detailed understanding and mastering of bodily functions and dysfunctions. Biomedical research promises new triumphs, but discontent with medical practice is all around. Since several decades this has been acknowledged and discussed. The philosophical traditions of phenomenology and hermeneutics have been proposed as promising ways to approach medical practice, by ways of a richer understanding of the meaning structures of health and illness. In 2000, Swedish philosopher Fredrik Svenaeus published a book where he proposes that the phenomenological hermeneutics of Martin Heidegger and also the reflections on health and illness of Hans-Georg Gadamer offer important ways to approach the nature of medicine. In particular, Svenaeus argues that the goal of medicine is to promote and restore health, and that health ought to be seen as "homelike being-in-the-world". Unhealth, illness, consequently should be understood as a situation where a person's "being-in-the-world" in characterized by that lack of the rhythm, balance and "tune" of everyday living that characterizes not "being at home". In this article, Svenaeus' position is briefly outlined. Questions are raised whether "unhomelikeness" is to be seen as a metaphor, and, if so, if it is a fruitful such. Furthermore, I discuss whether or not a discourse on health and illness in these terms may be misleading in a situation where the ontological presuppositions of Heidegger are lost out of sight and the popular understanding of health psychology predominates. I also approach the question whether Svenaeus' assumptions may inadvertently lead us to an unjustifiably broad understanding of the tasks of medicine. It is finally concluded that Svenaeus phenomenological and hermeneutical approach is both interesting and promising. There are, however, several questions that ought to be pursued further, and the step from philosophical analysis to everyday clinical discourse may be unexpectedly long and risky.

    Abstract [en]

    In today's society an increased use of social networking sites can be seen, which can present difficulties in deciding what is private and what is public. The questions and issues being discussed in this essay are made to determining how students at Karlstad University relate to the information published on Facebook. Through an explorative research design and methodological triangulation in the form of a questionnaire survey and focus group interviews, the authors seek to answer and discuss the students' different approaches to the use of Facebook.The paper shows that students at Karlstad University sometimes have a low awareness of the information displayed to others and inadequate use of the privacy settings available on the page. At the end of the study the authors discern three different categories of Facebook users with different levels of consciousness.

    Abstract [en]

    The nature and scope of medical humanities are under debate. Some regard this field as consisting of those parts of the humanistic sciences that enhance our understanding of clinical practice and of medicine as historical phenomenon. In this article it is argued that aesthetic experience is as crucial to this project as are humanistic studies. To rightly understand what medicine is about we need to acknowledge the equal importance of two modes of understanding, intertwined and mutually reinforcing: the mode of aesthetic imagination and the mode of analytical reflection.

    Narrativity and medicine: Some critical reflections2019In: Philosophy Ethics and Humanities in Medicine, ISSN 1747-5341, E-ISSN 1747-5341, Vol. 14, article id 9Article, review/survey (Refereed)
    Abstract [en]

    During the last three decades there has been a wave of interest in narrative and narrativity in the humanistic and the social sciences. This narrative turn has spilled over to medicine, where narrative medicine has gained a considerable influence.However, there have also appeared second thoughts on the role of narratives in our lives, as well as on what narratives may mean in relation to clinical medicine.This article presents some influential voices in this debate and scrutinizes the assumptions of narrative medicine in the light of these. It is concluded that there are sound reasons to tread this path with some caution and avoid the too far reaching ambitions on behalf of narrativity in relation to clinical medicine. However, narrative medicine should still be seen as a promising attempt within the broader scope of medical humanities to emphasize the importance of human subjectivity in clinical medicine.

    Why should physicians read?: Understanding clinical judgement and its relation to literary experience2010Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Is literary experience of any practical relevance to the clinician? This is the overall question addressed by this investigation, which starts by tracing the historical roots of scientific medicine. These are found to be intimately linked to a form of rationality associated with the scientific revolution of the 17th century and with “modernity”. Medical practice, however, is dependent also on another form of rationality associated with what Stephen Toulmin calls “the epistemology of the biographical”. The very core of clinical medicine is shown to be the clinical encounter, an interpretive meeting where the illness experience is at the centre of attention. The physician can reach the goals of medicine only by developing clinical judgement. Clinical judgement is subjected to close analysis and is assumed to be intimately connected to the form of knowledge Aristotle called phronesis.

    In order to explore how literature – drama, novels, poetry – may be related to clinical judgement, a view of literature is presented that emphasizes literature as an invitation to the reader, to be met responsibly and responsively. Literature carries a potential for a widened experience, for a more nuanced perception of reality – and this potential is suggested to be ethically relevant to the practice of medicine. The “narrative rationality” of a literary text constitutes a complement to the rationality pervading scientific medicine.

    The final step in my analysis is a closer exploration of the potential of the literary text to contribute to the growth of clinical judgement, in relation to the challenges of everyday clinical work. Some of the conditions that may facilitate such growth are outlined, but it is also shown that full empirical evidence for the beneficial effects of reading on the clinician reader is beyond reach.

    Abstract [en]

    When a person falls ill, their experience changes - sometimes in a very minor and transient way, sometimes in a decisive and lasting one. ‘Diagnosis’ is often seen as the process of scientifically and objectively identifying the causes of this subjective experience, but is the process and meaning of ‘diagnosis’ really as simple as this implies?

    As this volume of The Medical Humanities Companion argues, diagnoses are an answer to complex human needs that spring from being ill, and are in turn a complex, culturally mediated interaction between individuals, scientific discoveries, social negotiation and historical change. This volume makes visible the complexities and ambiguities involved in giving and receiving diagnoses, and how they shape and are shaped by views on what is real and acceptable, and how people relate to the phenomena of illness.

    Att ge eller att inte ge: En studie om projektledares arbete med återkoppling2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The background of our paper is that feedback is needed as a tool on during work to make the individuals feel comfortable. This is basically related to our need of feeling accepted and to feel affinity. Research has demonstrated that the confirmation from the outside world is an important part of the individual's selfimage. In a project based environment, feedback is important, as project groups often consist of new constellations of people who quickly must learn to work together. If feed-back could be used successfully, this can have positive effects on work perfor-mance. The problem of providing feedback is how to give it in a constructive way so the receiver to take in the information and accept it. By examining past research, we examined why there is a need for feedback in project teams, what the research says that the giver should consider when it comes to feedback, and what consequences and results of feedback could be. Our purpose is, based on existing research, to examine how feedback is used in practice for five project managers. We asked ourselves following questions: Do project managers provide feedback? In what ways? How do they work with feedback? Do they know how the theory looks about the topic? How do they work to become better at giving feedback? To examine the issues, we used a qualitative approach in the form of semi-structured interviews. The interview subjects were all working in the same indus-try, the real estate industry. Our interview data were processed by transcribing and coding by predetermined themes. In our analysis we compared the theoretical background of the empirical data we collected. A matrix with a compilation of the collected data is presented in appendix 2. Our conclusion is that project managers mostly work with positive feedback and that giving negative feedback is perceived problematic. We also discovered that the project managers lacked a theo-retical knowledge about the subject and that the skills they possessed, had they learned through experience.

    Den hållbara urbanplaneringens paradoxer: The paradoxes of unsustainable urban planning2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract  This paper has investigated two urban planning ideals that emerges in the planning process. The study's starting point has been sustainable development to study the two existing urban planning ideals today. This means that the compact city and the green city has been the main focus of this study, but sustainability has large space with many of the aspects that is expected to lead to sustainable development. A case study was used to investigate how Karlstad is working on the issue and how the paradox appears in the municipal planning. Karlstad is currently developing a new green structure plan. The study's empirical evidence is based on two interviews with Karlstad municipality officials. The municipal documents Karlstad municipality's comprehensive plan (2012) and Olmårs densification study (2007) has been used. The municipal documents and the interview material was analyzed through meaning content. The study's analysis is based on the study's empirical and theoretical background which shows that there is a paradox in Karlstad municipality's urban planning. It also shows a trend in which cities aim to achieve the sustainable city. As the concept of sustainability is a diffuse concept, the compact city and the green city has become a complex strategy to achieve the sustainable city. This means that the green and compact city can be viewed from several different angles. Karlstad municipality's vision of the compact city is to have a compact city especially in the central parts of the city. These areas are green areas today. A planning dilemma between the aspirations of the planning arises, in which these must be weighed against each other. This means that if the green structure is prioritized then another aspect must be weighed out. In other words; there is a paradox in Karlstad municipal´s urban planning, and this means that if the green structure priority needs another aspect weighed out. This means that there is a paradox in municipal urban planning, and this is shown in this paper.

    Teaching and Learning second language: A comparison of teaching and learning Arabic and Dari languages in Secondary Schools of Kabul.2015Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    Afghan languages are, influenced by Arabic in the field of academic terms. Also, several Arabic words need to be learnt for daily conversation in Afghanistan. This study is about students and teachers’ views about learning and teaching Arabic and Dari as two second languages in the areas of Kabul where the residents’ native language as well as the language of instruction is Pashto. The aim of the study is to explore similarities and differences between teaching and learning Arabic and Dari in secondary schools of Kabul.

    The data for this quantitative study was collected from 9 schools in the eastern part of Kabul, Information was gathered through separate questionnaires for teachers and students as well as textbook analysis. The schools were selected via purposive sampling. A total of 60 students and 50 teachers (25 Dari and 25 Arabic) participated in this study.

    The main findings of the study included that all students are interested in learning both Arabic and Dari for various reasons. However, learning language helps students to understand the context of the textbooks and get knowledge about this is true about learning Arabic as it is a foreign language too.

    While teaching the languages, teachers only help students improve listening and reading skills as the teachers do most of the talking in class only sometime ask the students to repeat the lesson from textbook. The remaining two important skills i.e. writing and speaking are widely ignored because the teachers ask the students to do the writing at home and provide little time for verbal conversations inside class due to limited time.

    Likewise, the teachers thought it is important to focus on developing reading skills among students and very little or no attention is given to improving writing skills. In addition, memorization and recalling of information when required is the dominant feature of teaching in the schools I studied in this study.

    Arabic and Dari languages have lot of similarities, from having same alphabets to lot of common words. In my study most of students’ were interested to learn both Dari and Arabic, but the obstacle they faced during learning Arabic was, that there was not enough qualified Arabic language teachers but number of qualified teachers in Dari language was a lot and that made learning Dari easier for students who were interested.

    Generally, the results of this research confirm many previous results. However, a lot need to be done by teachers, school management and education authorities to improve the learning and teaching situations.

    SOME FACTORS INFLUENCING STUDENTS’ EDUCATION IN AFGHANISTAN: A study of students’ drop   out and retention rates of boys and girls of primary schools in Maidan Wardak   Province - Afghanistan2013Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    School access and staying in school is one the most important issue for the Ministry of Education in Afghanistan particularly for girls. According to the Ministry of Education (MoE), nearly seven million children have access to school in Afghanistan, 37 per cent of whom are girls.

    Students drop out of schools before completing their education cycle, to know who drops out and to what extent; this study describes some of factors that influence students to drop out of school in grade 4 and grade 6.

    To find out some factors that may influence girls and boys to drop out of schools in grade 4 and 6 six, structured interviews were conducted in 10 schools – 5 in rural area and 5 in urban area of Maidan Wardak province of Afghanistan. Data was collected by random sample from 32 girls and 48 boys who left schools. 20 teachers and 20 parents were also interviewed to know what their opinions are on drop out of students.

    After data collection, several factors were found to cause students drop out of schools; some of the most prominent causes were Poverty, lack of security, long distance to school and socio- culture factors.

    By looking to the current educational situation of the Ministry of Education in Afghanistan, there is a need of research almost in all areas particularly in the area of girls’ education.

    Abstract [en]

    Abstract—Smart TVs are coming to dominate the televisionmarket. This accompanied by an increase in the use of the smartTV applications (apps). Due to the increasing demand, developersneed modeling techniques to analyze these apps and assess theircomprehensiveness, completeness, and quality. In this paper, wepresent an automated strategy for generating models of smartTV apps based on a black-box reverse engineering. The strategycan be used to cumulatively construct a model for a given app byexploring the user interface in a manner consistent with the use ofa remote control device and extracting the runtime information.The strategy is based on capturing the states of the user interfaceto create a model during runtime without any knowledge ofthe internal structure of the app. We have implemented ourstrategy in a tool called EvoCreeper. The evaluation results showthat our strategy can automatically generate unique states anda comprehensive model that represents the real user interactionswith an app using a remote control device. The models thusgenerated can be used to assess the quality and completeness ofsmart TV apps in various contexts, such as the control of otherconsumer electronics in smart houses.

    Aspects of Quality in Internet of Things (IoT) Solutions: A Systematic Mapping Study2019In: IEEE Access, E-ISSN 2169-3536, Vol. 7, p. 13758-13780Article in journal (Refereed)
    Abstract [en]

    Internet of Things (IoT) is an emerging technology that has the promising power to change our future. Due to the market pressure, IoT systems may be released without sufficient testing. However, it is no longer acceptable to release IoT systems to the market without assuring the quality. As in the case of new technologies, the quality assurance process is a challenging task. This paper shows the results of the first comprehensive and systematic mapping study to structure and categories the research evidence in the literature starting in 2009 when the early publication of IoT papers for IoT quality assurance appeared. The conducted research is based on the most recent guidelines on how to perform systematic mapping studies. A set of research questions is defined carefully regarding the quality aspects of the IoT. Based on these questions, a large number of evidence and research papers is considered in the study (478 papers). We have extracted and analyzed different levels of information from those considered papers. Also, we have classified the topics addressed in those papers into categories based on the quality aspects. The study results carry out different areas that require more work and investigation in the context of IoT quality assurance. The results of the study can help in a further understanding of the research gaps. Moreover, the results show a roadmap for future research directions.

    Code-Aware Combinatorial Interaction Testing2019In: IET Software, ISSN 1751-8806, E-ISSN 1751-8814Article in journal (Refereed)
    Abstract [en]

    Combinatorial interaction testing (CIT) is a useful testing technique to address the interaction of input parameters in software systems. In many applications, the technique has been used as a systematic sampling technique to sample the enormous possibilities of test cases. In the last decade, most of the research activities focused on the generation of CIT test suites as it is a computationally complex problem. Although promising, less effort has been paid for the application of CIT. In general, to apply the CIT, practitioners must identify the input parameters for the Software-under-test (SUT), feed these parameters to the CIT tool to generate the test suite, and then run those tests on the application with some pass and fail criteria for verification. Using this approach, CIT is used as a black-box testing technique without knowing the effect of the internal code. Although useful, practically, not all the parameters having the same impact on the SUT. This paper introduces a different approach to use the CIT as a gray-box testing technique by considering the internal code structure of the SUT to know the impact of each input parameter and thus use this impact in the test generation stage. We applied our approach to five reliable case studies. The results showed that this approach would help to detect new faults as compared to the equal impact parameter approach.

    Estimated Droop Control for Parallel Connected Voltage Source Inverters: Stability Enhancement2013Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Renewable Energy Sources (RES) are considered as the replacement of conventionalenergy sources. These RES can use wind energy, solar light, bio waste and can alsobe in the form of small hydro power units. These RES has very poor power qualityand contains voltage uctuations and variable frequency. These factors make RES astability risk for the main utility grid. As a solution, currently inverters with dierentdesign techniques are being used as an interface between RES and main utility grid. Thecurrent study proposed a new technique "estimated droop control" for inverter design.The conventional droop control technique which was already used in inverter design, hasdiculty in synchronizing parallel connected inverters with dierent droop gains and lineimpedances. The proposed "estimated droop control" does not use any predened droopvalues for inverters and all inverters are responsible for the estimation of their own droopvalues with respect to their output power. Therefore, inverters are not bound to usesame and static droop values which are considered as a vital communication link. Theproposed design methodology has made inverters independent from this only virtual linkof communication due to which the reliability of a system has increased. The proposeddesign technique has given very good results in a simulation run. When the Simulinkmodel was run in parallel connected inverter with dierent line impedances, it was asuccess as both inverters started operating with same droop values as they were sharingan equal load. The most important test was with dierent line impedances because inconventional droop control it is dicult for inverters to keep their synchronism withdierent line impedances and an unequal load sharing make inverters to deviate fromtheir nominal values and to generate dierent tracking signals for each set. This problemhas been successfully solved with estimated droop control as in this method each inverterset its droop gains according to its output power, which helps an inverter to operate atnominal values with dierent droop gains and line impedance.

    Service Quality in Accounting Firms: its Effect on Client Satisfaction and Loyalty: A quantitative study based on the Swedish listed companies2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Background: The quality of service is considered as an essential component in any service industry. It has been evolved in service marketing and has often been used in other research fields and sectors. Further, researchers have emphasized the importance of measuring the quality dimensions over years and in various industries in order to manage it. Also, they have proposed that enhancing the quality of services enhances customer satisfaction and loyalty, in turn that will enable the service provider to meet the changes and challenges in its business environment.

    Purpose: Based on listed companies’ perception at Nasdaq Stockholm OMX, the study seeks to evaluate the service quality provided by accounting firms in Sweden and determine the situation of its dimensions, as well as to explore their direct impact on the client satisfaction and client loyalty. In addition, the study utilizes the SERVPERF model to measure the service quality’s dimensions.

    Approach/methodology: To achieve the purpose, the study conducts a deductive and quantitative approach with explanatory purpose. Also, the data has been collected based an online questionnaire. It was sent to 450 listed companies at Nasdaq Stockholm OMX, resulting in a sample of 58 respondents. The analysis has been conducted based on regression analysis.

    Result/discussion: the research presents and discusses the result based on two hypotheses groups separately. The first hypotheses group regarding the impact of service quality and its dimensions on customer satisfaction. The second hypotheses group concerning the impact of service quality and its dimensions on customer loyalty.

    Originality: To the researcher’s knowledge this study is considered as a first attempt using a multi-dimension scale to assess the service quality of the accounting firms in Sweden based on the perception of Swedish listed companies.

    Cooperative Spectrum Sensing for Cognitive Radio Networks2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The great developments in the field of wireless communications that has been accelerated by the commercial need for better services has led to the application of wireless systems in many fields of life. The effect of wireless technology is much widened, like for safety applications, home automation, smart grid control, medical wearable, embedded wireless devices, entertainment systems etc.

    Direct and indirect surveillance of spectrum treatment has acknowledged the sequential and spatial accessibility of spectrum inside allocated frequency bands. This implies that spectrum deficiency is becoming a main problem. Therefore, spectrum deficiency problem arises here in terms of that most of the licensed primary users are not using their spectrum due to any reason of either geographical variation or temporal basis, and lot of allotted spectrum is unused and under-utilized. Moreover, along with spectrum deficiency problem, other issues are also linked like interference caused by secondary unlicensed users to primary licensed users while sharing the work load among each others, and problem of vacating the spectrum band in less fewer time frames after primary users detection.

    Cognitive networks assure to tackle these spectrum deficiency and other associated problems by accommodating secondary (unlicensed) users, in the spectrum region which is under-utilized. Spectrum Sensing is the prime motivation for cognitive radio and ensures that secondary (unlicensed) users do not propose unbearable levels of interference to primary (licensed) users.

    Cooperative Spectrum Sensing methodologies are still an open window of research. This work is related to cope up the problem of spectrum deficiency and associated problems, by developing an approach for establishment of grouping/clustering between secondary users in a cooperative spectral environment. This approach ensures that members within a group are highly correlated. As a result, the workload on each sensing node within a group is reduced. The effectiveness of this approach depends upon the accuracy of fused decision related to the presence or absence of primary (licensed) user at a particular band (50MHZ to 100MHZ). This approach also depends on the factor that time taken in sensing the primary (licensed) users should be less enough so that decision in vacating the band by the Cognitive Radio secondary users could be taken in fewer time frames. This latter metric is known to be ‘agility’, which eventually comes with the outcome of minimum interference to primary users via their early recognition.

    Att identifiera signaler för obestånd i tid2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    To be able to protect themselves from credit risk, the banks must constantly check the performance of  the companies they have lent money to. There are many mathematical models for predicting financial distress. These models use accounting-based ratios, which often are historical and not representative for the present situation. This study describes how the banks do in practice to find signals of insolvency in time and the variables they are observing for doing that.

    In addition to financial reports which the company sends in to the bank at least once a year, also the relationship between them and information from different information  agencies are of great importance to track  signals of insolvency. Poor profitability is the primary cause of insolvency. It is caused mainly because of bad business and leadership.  Eventually will  poor profitability lead  to consuming of equity capital and place the company in an illiquid situation. Then it may be difficult for the company to pay their bills and signals of insolvency become obvious and  the  banks start then to sharpen  their attention on the companies and intensify the follow-up works.

    Another find-out  of the  study  is  that local factors which  are  contributing to failure are  the  large companies that are active  in the area. When they are in a bad situation, it affects the suppliers. The big difference between service and manufacturing companies  regarding insolvency  is  that service companies are more flexible regarding cutting down costs when bad times come.

    Racing Driver Model in Dymola Vehicle Dynamics Library (VDL): Steering Controller Design2012Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Racing drivers always want to traverse path at vehicle’s maximum performance limits while keeping the vehicle at its ideal trajectory. The main objective of this report is to elaborate strategy for the path following problem in which driver has to follow the predefined 2D roads. New steering controller design for closed loop racing driver model in Dymola vehicle dynamics library is developed. The methodology proposed by Sharp et al. [2] is followed with the optimal velocity profile that tries to mimic the actions of the real drivers in real time scenarios. Vehicle handling limits i.e. longitudinal and lateral limits are defined before simulation. While travelling in the neighbourhood of optimal velocity on the straight road as well as during the curves, the performance of the steering controller is tested by conducting the test on J turn, Clothoid, Extended chicane and the closing curve path and also tested during the different environment effects e.g. when there is a side wind affecting the vehicle. Performance of existing and new steering controllers discussed and compared in result chapter. It is ensured that the drawbacks in the existing steering controller are eliminated by using the proposed methodology in new implemented steering controller.

    Key Words: Driver Model, Steering Controller, Path following, Velocity profile
