    Annexin A1 expression in blood mononuclear cells: a potential marker of glucocorticoid activity in patients with coronary artery disease2014Manuscript (preprint) (Other academic)
    Abstract [en]

    An imbalance between pro- and anti-inflammatory actions is believed to drive progression of atherosclerosis. Annexin A1 (AnxA1) is a key player in resolution of inflammation and a mediator of anti-inflammatory effects of glucocorticoids. Here, we investigated whether expression of AnxA1 in peripheral blood mononuclear cells (PBMCs) was altered in patients with coronary artery disease (CAD) and also related findings to glucocorticoid sensitivity ex vivo.

    We included 57 patients 6-12 months after acute coronary syndrome (ACS), 10 patients with ACS, and healthy controls. AnxA1 mRNA was measured in PBMCs and AnxA1 protein was assessed in monocytes and lymphocyte subsets by flow cytometry. In post-ACS patients and controls, glucocorticoid sensitivity was determined by measuring inhibitory effects of dexamethasone on LPS46 induced cytokine secretion.

    AnxA1 mRNA levels in PBMCs were higher in patients compared with controls, although most pronounced in ACS patients. AnxA1 protein was most abundant in the monocyte fraction. ACS patients exhibited the highest levels of cell surface-associated AnxA1 protein while levels in post-ACS patients and controls were similar. Ex vivo assays showed that PBMCs from post-ACS patients were more prone to release IL-6. Glucocorticoid sensitivity correlated with cell surface-associated AnxA1 protein in peripheral monocytes. Dexamethasone also induced upregulation of AnxA1 mRNA.

    AnxA1 expression in PBMCs is closely associated with glucocorticoid actions and cell surface associated AnxA1 appears to be a marker of glucocorticoid sensitivity. Although still speculative, a “normal” expression of cell surface-associated AnxA1 in post-ACS patients may suggest that glucocorticoid actions in vivo are insufficient to provide adequate anti-inflammatory effects in these patients.

    Annexin A1 in blood mononuclear cells from patients with coronary artery disease: Its association with inflammatory status and glucocorticoid sensitivity2017In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, no 3, e0174177Article in journal (Refereed)
    Abstract [en]

    Annexin A1 (AnxA1) is a key player in resolution of inflammation and a mediator of glucocorticoid actions. In atherosclerotic tissue, increased expression of AnxA1 has been associated with protective plaque-stabilizing effects. Here, we investigated the expression of AnxA1 in peripheral blood mononuclear cells (PBMCs) from patients with coronary artery disease (CAD). Blood was collected from 57 patients with stable CAD (SCAD) and 41 healthy controls. We also included a minor group (n = 10) with acute coronary syndrome (ACS). AnxA1 mRNA was measured in PBMCs. Expression of AnxA1 protein (total and surface-bound) and glucocorticoid receptors (GR) were detected in PBMC subsets by flow cytometry. Also, salivary cortisol, interleukin(IL)-6 and IL-10 in plasma, and LPS-induced cytokine secretion from PBMCs, with or without dexamethasone, were assessed. AnxA1 mRNA was found to be slightly increased in PBMCs from SCAD patients compared with controls. However, protein expression of AnxA1 or GRs in PBMC subsets did not differ between SCAD patients and controls, despite SCAD patients showing a more proinflammatory cytokine profile ex vivo. Only surface expression of AnxA1 on monocytes correlated with dexamethasone-mediated suppression of cytokines. In ACS patients, a marked activation of AnxA1 was seen involving both gene expression and translocation of protein to cell surface probably reflecting a rapid glucocorticoid action modulating the acute inflammatory response in ACS. To conclude, surface expression of AnxA1 on monocytes may reflect the degree of glucocorticoid sensitivity. Speculatively, "normal" surface expression of AnxA1 indicates that anti-inflammatory capacity is impaired in SCAD patients.

    Higher expression of annexin A1 in 1 CD56+ than in CD56-T cells: Potential implications for coronary artery disease2014Manuscript (preprint) (Other academic)
    Abstract [en]

    Background: Increased proportions of circulating proinflammatory CD56+ T cells have been reported in patients with coronary artery disease (CAD). Yet, little is known about regulation of these cells. In the present study, we investigated the expression and potential role of the glucocorticoid-mediated protein annexin A1 (AnxA1) in CD56+ and CD56-T cell subsets, with focus on CAD.

    Methods and Results: We included totally 52 healthy individuals, 28 patients with acute coronary syndrome (ACS) and 57 patients with a history of ACS. AnxA1 mRNA expression was assessed in peripheral blood mononuclear cells. AnxA1 protein expression (total and cell surface-associated) was measured by whole blood flow cytometry in circulating CD56+ and CD56- T cell subsets. Furthermore, inhibitory effects of dexamethasone and/or recombinant AnxA1 on cytokine secretion by CD56+ and CD56- T cells were explored in vitro. We found that CD56+ T cells (the majority CD8+), expressed higher levels of AnxA1 mRNA and protein than did CD56- T cells. When comparing CAD patients with healthy controls, significantly higher levels of cell surface-associated AnxA1 expression were seen in patients, most pronounced in ACS patients. In vitro, dexamethasone reduced cytokine secretion by CD56+ T cells, whereas AnxA1 alone had no effect, and AnxA1 combined with dexamethasone abolished the dexamethasone-induced suppressive effects.

    Conclusion: AnxA1 was expressed more abundantly in proinflammatory CD56+ T cells. Patients with ACS exhibited increased levels of cell surface-associated AnxA1, thus indicating increased activation of the AnxA1 pathway. Our data further suggested that AnxA1 might counteract glucocorticoid mediated anti-inflammatory effects in T cells.

    Back extensor training increases muscle strength in postmenopausal women with osteoporosis, kyphosis and vertebral fractures2011In: Advances in Physiotherapy, ISSN 1403-8196, E-ISSN 1651-1948, Vol. 13, no 3, 110-117 p.Article in journal (Refereed)
    Abstract [en]

    We determined the efficacy of a back muscle extensor strengthening program on the back muscle extensor strength, kyphosis, height and thoracic expansion in women with at least one vertebral fracture, kyphosis and osteoporosis. Thirty-six patients were included and randomized to a control or a training group. The training focused on back muscle extensor strengthening program for 1 h, twice a week for 4 months and was performed by a physiotherapist. The main outcome measure was the back muscle extensor strength. In an intention-to-treat analysis no significant effects on back muscle strength in the training group vs. controls could be seen (p = 0.74). In a per-protocol analysis (n = 28), the training group increased back muscle strength from 290 ± 87 to 331 ± 89 N while the control group showed no improvement. After adjusting for the strength at baseline, a significant effect of training could be demonstrated (p = 0.029). When comparing the heights between the groups a significant group × time interaction was observed (p = 0.012) where the training women increased their mean height with 0.3 cm (p = 0.101) and controls decreased 0.44 cm (p = 0.045). The training group improved their thoracic expansion compared with baseline (p = 0.03). No effect of training on kyphosis was seen. In conclusion, a 4-months back extensor training program can improve back strength and seems to maintain height and thoracic expansion.

    Skyddet för polisens kännetecken2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Polisen är en central samhällsfunktion, och för att erhålla ett fungerande och tryggt samhällekrävs medborgarnas förtroende. Polisens tillförlitlighet måste därför ständigt upprätthållas ochskyddas. Polisens kännetecken återfinns bland annat på polisens uniformer, utrustning samtutryckningsfordon. Syftet med kännetecknen är att stärka trovärdigheten i mötet med medborgaresamt bidra till känslan av samhörighet inom polismyndigheten. Det ska vara lätt attkänna igen polisen oavsett plats, och det ska aldrig råda någon tvekan om att polisen verkligenär polisen. Trots detta finns det inget generellt skydd för polisens kännetecken.I lagen (1970:498) om skydd för vapen och vissa andra officiella beteckningar finns skydd föranvändning av polisvapnet, som är en del av polisens logotyp och kännetecken, i näringsverksamhet.Något förbud mot att använda polisens kännetecken för privat bruk existerar inte, omanvändandet inte faller under bestämmelsen i 17 kap. 15 § BrB om föregivande av allmänställning. Det har i rättspraxis inte ansetts vara föregivande av allmän ställning att på väg elleri terräng framföra ett fordon som är försedd med polisens kännetecken. Det är även tillåtet attför vem som helst förse fordon med sådana kännetecken. Polisens uniformspersedlar och annanutrustning finns att köpa på den öppna marknaden, trots att polisens föreskrifter om uniformeroch utrustning fastställer att Polismyndigheten äger all uniformspersedel med tillbehöroch utdelar detta endast som lån. Det föreligger emellertid inget förbud för andra än Polismyndighetenatt äga sådan utrustning.Det finns ingen reglering vad gäller användningen av polisens kännetecken i konstnärlig verksamhet.Inte heller finns det någon reglering för de företag som tillhandahåller polisfordonoch annan polisiär rekvisita.Att vem som helst kan köpa och äga uniformer och fordon försedda med polisens kännetecken,och använda helt fritt i konstnärlig verksamhet, kan leda till stora skador i relationen mellanmedborgare och polisen. Trots att det finns de som endast har ett genuint intresse för polisiäraobjekt måste hänsyn tas till vilka oönskade konsekvenser som kan uppkomma om sådanaobjekt hamnar i fel händer.

    Ethyl glucuronide concentrations in two successive urinary voids from drinking drivers: Relationship to creatinine content and blood and urine ethanol concentrations2003In: Forensic Science International, ISSN 0379-0738, E-ISSN 1872-6283, Vol. 133, no 1-2, 86-94 p.Article in journal (Refereed)
    Abstract [en]

    The concentrations of alcohol in blood (BAC) and two successive urine voids (UAC) from 100 drunk drivers were compared with the concentration of ethyl glucuronide (EtG), a minor metabolite of ethanol in urine, and the urinary creatinine content as an indicator of dilution. The subjects consisted of 87 men with mean age 42.2 ▒ 14.2 years (▒standard deviation, S.D.) and 13 women with mean age 42.5 ▒ 14.4 years. Ethanol was measured in blood and urine by headspace gas chromatography (GC) and EtG was determined in urine by liquid chromatography-mass spectrometry (LC-MS). The mean UAC was 2.53 ▒ 1.15g/l for first void compared with 2.35 ▒ 1.17g/l for second void, decreasing by 0.18 ▒ 0.24g/l on average (P < 0.001 in paired t-test). The ratios of UAC/BAC were 1.35 ▒ 0.25 for first void and 1.20 ▒ 0.16 for second void and the difference of 0.15 ▒ 0.27 was statistically significant (P < 0.001). The UAC/BAC ratio was not correlated with creatinine content of the urine specimens, whereas the concentration of urinary EtG was positively correlated with creatinine (r=0.64 for first void and r=0.62 for second void). The UAC was not correlated with urinary EtG directly (r=-0.03 for first void and r=0.08 for second void) but after adjusting for the relative dilution of the specimens (EtG/creatinine ratio) statistically significant positive correlations were obtained (r=0.58 for first void and r=0.57 for second void). The dilution of the urine, as reflected in creatinine content, is important to consider when EtG measurements are interpreted. The excretion of EtG in urine, like glucuronide conjugates of other drugs, is influenced by diuresis. EtG represents a sensitive and specific marker of acute alcohol ingestion with applications in clinical and forensic medicine. ⌐ 2003 Elsevier Science Ireland Ltd. All rights reserved.

    Successful Destination Branding?: A case study of DMOs in Brussels, Istanbul and Stuttgart2009Independent thesis Advanced level (degree of Master (One Year)), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Tourism is an important source of economic growth for destinations, which is why the interest for destination branding has grown in recent years. Meanwhile, Destination Marketing Organisations (DMOs) often struggle to promote their destination successfully. For instance, many stakeholders influence the perception of a destination and therefore it is difficult to create a coherent image. Some destinations have a more successful destination branding, which not only depends on their marketing methods but also the pre-requisites of the city. Hence, destination branding is a complex process where there is no standard solution. Therefore, three different destinations are used as a basis for the thesis; Brussels, Istanbul and Stuttgart. What can be learned from the marketing methods in these destinations? The purpose of this thesis is to examine the current market position of Brussels, Istanbul and Stuttgart as tourist destinations and their marketing strategies and methods used to promote the destinations. We will identify general recommendations on how to improve the destination branding, and propose specific recommendations to selected DMOs in the destinations.

    Through the use of specific descriptive criteria, such as unique selling points (USPs), image and marketing channels, as well as the conducting of interviews with employees in higher administrative positions within the selected DMOs, the thesis aims at providing the reader with a deeper knowledge in the field of destination branding. The Tourist Area Lifecycle Model was used to analyse the destinations to understand their situation today and future possibilities and challenges in marketing the cities as tourist destinations. Moreover, the concepts of comparative and competitive advantages and the integrative model by Ritchie and Croutch was used to discuss the competitiveness of the destinations. The research shows that DMOs face problems, such as the lack of a coherent image, common goals, the coordination of activities between DMOs in different levels and cooperation between different stakeholders. These are areas that need attention from the DMOs in order to achieve successful destination branding and are included in the conclusion, which helps DMOs to improve their marketing methods in order to achieve success in the promotion of their destination.

    Codeposition of apolipoprotein A-IV and transthyretin in senile systemic (ATTR) amyloidosis2001In: Biochemical and Biophysical Research Communications - BBRC, ISSN 0006-291X, Vol. 285, no 4, 903-908 p.Article in journal (Refereed)
    Abstract [en]

    Protein material was extracted from amyloid-rich sections of formalin-fixed and paraffin-embedded heart tissue from an individual with senile systemic amyloidosis, known to contain wild-type transthyretin as major amyloid fibril protein. Amino acid sequence analysis of tryptic peptides of this material revealed in addition to transthyretin sequences, also amino acid sequence corresponding to an N-terminal fragment of apolipoprotein A-IV. In immunohistochemistry, an antiserum to a synthetic apolipoprotein A-IV peptide labeled amyloid specifically. This peptide formed spontaneously amyloid-like fibrils in vitro and enhanced fibril formation from wild-type transthyretin. We conclude that several apolipoproteins, including apolipoprotein A-IV, may be important minor amyloid constituents, promoting fibril formation.

    Cost effective optimization of system safety and reliability2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    A method able to analyze and optimize subsystems could be useful to reduce project cost, increase subsystem reliability, improve overall aircraft safety and reduce subsystem weight. The earlier the optimization of development of an aircraft in the design phase can be performed, the better the yield of the optimization becomes. This master thesis was formed in order to construct an automatic analysis method, implementing a Matlab script, evaluating devices forming aircraft subsystems using a Genetic Algorithm. In addition to aircraft subsystems, the method constructed in the work is compatible with systems of various industries with minor modifications of the script.

    Value creation and relationships in transformation: A study of social media in the travel industry2010Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In recent years the Internet has greatly changed the travel industry and the emergence of social media has driven this change further. In the past travel companies have been natural links between customers and suppliers but today customers can buy travel directly from the supplier, making it difficult for travel companies to attract new customers and retain existing customers. As social media is revolutionizing the way people communicate, the trend suggests that it is becoming increasingly important for firms to take part in this technological development to interact with customers.

    Although Internet and social media has a major impact on firm-to-customer and customer-to-customer conversations, there is little guidance in academic literature and organizational contexts on how to use social media in an effective way. Therefore, the aim of this thesis is to describe and explain how social media has transformed the relationships between selected Swedish travel companies and their customers, and how these firms create and sustain value and relationships through social media. Furthermore, we will give implications for management on how to utilize social media to create and sustain value and relationships.

    The results of our research confirm that social media is transforming the relationships between firms and customers. From our findings we conclude that the customer has become more empowered, that interaction now occurs through a two-way communication and that social media has made industries and relationships more transparent. The results also indicate that firms do not realize the value that can be created through social media for the customer as well as for the firm. The use of social media among the interviewed firms varies with some firms using social media through many tools and some firms not using social media at all.

     

    Our findings implicate that being aware of what value is created and why the firm is involved in a certain social media tool increases the likelihood of success. The firm should further not be afraid to experiment with social media. However, social media also presents challenges. As social media is characterized by rapidly changing trends, it is difficult to predict what will happen not only in a distant future, but even so just a few years ahead.

    Konkurrens vid offentlig upphandling: Särskilt avseende oseriösa anbud2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Lagarna om offentlig upphandling har som syfte att bidra till att den inre marknaden inom EU upprätthålls. Osund konkurrens förhindrar att offentliga myndigheter gör bra affärer. Förekomsten av oseriösa anbudsgivare och bristande kontroller från upphandlande myndigheter gör att skattepengar som skulle kunna användas inom välfärden går förlorade. Upphandlingsreglerna ska säkerställa att myndighet inte använder offentliga medel på ett otillbörligt sätt och därav säkra att inga leverantörer gynnas eller missgynnas. Upphandlingsreglerna har en lång historisk utveckling och ämnar konstant att bli modernare och enklare samt garantera en rättvis konkurrens mellan leverantörerna.

    Oseriösa anbud kan förekomma i flera olika former. I uppsatsen redogörs för vilka dessa former kan vara, samt hur upphandlande myndighet har möjlighet att med hjälp av upphandlingsreglerna förhindra att sådana anbud antas. Angående förhindrandet av oseriösa anbud leder till att bevisfrågan blir av intresse. Bevisbördans placering gällande ett anbuds seriositet redogörs för med hjälp av främst HFD:s nya domar om onormalt låga anbud men även EU-domstolens praxis. Det spekuleras även över hur den eventuella förseningen av införlivandet av det nya upphandlingsdirektivet kommer att påverka de offentliga upphandlingarna i Sverige.

    I analysen utreds frågeställningarna är det möjligt att förhindra att oseriösa anbud antas och hur påverkar oseriösa anbud konkurrensen vid offentlig upphandling där bland annat slutsatsen blir att upphandlande myndigheters kontroll av leverantörer bör vidgas samt att det är av vikt att uppnå en sund marknad med bra konkurrens, vilket innebär att oseriösa anbud måste motarbetas. I dagsläget får det fortfarande anses oklart gällande begreppen oseriösa anbud samt oseriösa leverantörer, men insikten om att en motarbetning är behövlig för att uppnå EU:s inre marknad, får anses vara upp-märksammad.

    Workshopmetodik för uppstart av nya projekt inom mobil IT2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Workshops have become a familiar phrase during the last decade. It is a useful and popular way of working, which has led to workshops methodology being of great interest to a numerous amount of companies. One type of workshop is the idea generating workshop. During these it is desirable that the participants have a common objective during the workshop, which at times can be hard to achieve.

    The purpose of the case study was to create a workshop methodology surrounding mobile applications. The workshop focuses on creating a common objective for the participants and letting the company representatives focus on their potential users.

    Several criteria were extracted from a literature study, interviews and requests provided from the company Sogeti. These criteria were then used to select suiting techniques and with them, create a workshop methodology. The workshop was tested and analyzed twice, by performing test runs. This was to be able to see whether the workshops would work as expected in a real life scenario or not.

    The end result is a workshop methodology with elaborately chosen techniques. During the test cases the workshop met its demands on a common objective, as well as having the participants centering their idea generation on their end users through the whole workshop.

    The conclusions made from the study were that this method should work fine when used as an idea generating workshop, especially when used in the context of mobile applications. The different parts of the workshop which are crucial for it to reach a desirable result have also been identified as; purpose description, Empathy map, Nominal group technique and 20-20 vision.

    Lättläst lättare: Utformningen av ett grafiskt gränssnitt för en automatisk textförenklare profilerat mot webbredaktörer2016Independent thesis Basic level (degree of Bachelor), 12 credits / 18 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie var att ta fram ett förslag på hur ett gränssnitt för en automatisk textförenklare profilerad mot webbredaktörer vid Linköpings universitet skulle kunna se ut. För att åstadkomma en välgrundad utformning har studien undersökt webbredaktörers arbetssätt och behov, och utforskat lösningar på liknande problem i andra verktygsgenrer. För att uppnå syftet har tre frågeställningar ställts upp: 1) Hur kan ett stödverktyg för att skriva lättläst utformas för att passa webbredaktörer vid Linköpings universitet?, 2) Vad finns för existerande lösningar på liknande designproblem? Och 3) Givet funktionaliteten i verktyget, hur bör ett gränssnitt utformas? För att besvara den första frågeställningen utfördes intervjuer med sex olika webbredaktörer. I besvarandet av den andra frågeställningen utfördes en förebildsanalys på liknande verktyg för att identifiera potentiella lösningar. Slutligen presenteras en prototyp baserad på de första frågeställningarna och vissa typografiska avväganden som ett svarsförslag till den tredje frågeställningen. Resultaten visar på att ett textförenklingsgränssnitt profilerat mot webbredaktörer kräver skilda funktioner från textförenklingsverktyg riktade mot en målgrupp med lässvårigheter.

    Value stream mapping at SAAB Aeronautics2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Detta examensarbete handlar om att skapa en flödeskartläggning samt utvärdera materialförsörjningen mellan Saab Aeronautics och deras tredjepartslogistiker Servistik. Servistik försörjer Saabs produktion med material och dylikt med hjälp av det s.k. linjeflödet på vilket transporterna sker. Nu står Saab inför en taktökning, närmare bestämt för flygplanet Gripen E. Målet med detta arbete har varit att ta fram ett underlag för hur denna taktökning kan påverka materialförsörjningen, samt ge förslag på lösningar kring hur linjeflödet ska kunna hantera detta. Redan idag finns det tillfällen då allt material riskerar att inte får plats på linjeflödets fordon, och det är tydligt att linjeflödet måste ses över och modifieras vid en framtida taktökning. Genom observationer och intervjuer har en flödeskartläggning gjorts för att tydliggöra hur linjeflödet är uppbyggt samt fungerar i dagsläget. Syftet med flödeskartläggningen var att identifiera vilka flaskhalsar och problem som uppstått alt. kan uppstå på och kring linjeflödet. Utifrån observationer har beräkningar genomförts för att erhålla ett genomsnittligt medelvärde för de pallar och lådor som är vanligast förekommande som emballage på linjeflödet. Dessa värden har använts för att beräkna procentuella ökningar i materialmängd. Därefter har ett antal lösningsförslag tagits fram för hur olika flaskhalsar och scenarier kan hanteras. De två främsta förslagen som presenteras i detta examensarbete är att dels införa s.k. slot-tider för externa transportörer i godsmottagningen på området, samt att dela upp linjeflödets nuvarande rutt i två mindre rutter. Detta för att både kunna eliminera flaskhalsen som uppstår i godsmottagningen som innebär förseningar i linjeflödets transporter, men även för att senare kunna hantera den ökade mängd material som ska transporteras till respektive hus för produktion.

    Is Visual Stimuli Neighboring Attended Stimuli Suppressedin High Perceptual Load?: A Steady State Evoked Potential Study2016Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Perceptual load theory, together with the surround-suppression model suggest that stimulus surrounding attended stimuli is suppressed, especially if perceptual load is high. This study attempts to map surround-suppression using electroencephalography to measure neural activity related to suppression at four surrounding locations (2°, 3°, 4° and 6° from fixation). Color and orientation was used to manipulate load, and the effect of load was controlled through behavioral and neural measures using event related potentials. Our results demonstrate no statistically supported effect of load in behavioral data or SSVEP data, but unexplained increased neural amplitude of an early visual component (i.e. N1) in the (hypothesized) low load condition.

    Abstract [en]

    Children who have fled to Sweden, without their parents or guardians, have been a controversial subject during the winter of 2002. Their situations on refugeestations and the responsibiliy by community and the state have been discussed. My composition is about these children. The composition is not about the situations of the children - focus is instead on the people who operate with the children; community, state and organisations. I want to find empirical levels which show what the children associate with. I have found three levels that I have called: "A institutional refugee", "To be refugee - a problem which must be solved "and "Child or refugee?". These levels contains different subjects as laws, cultural, living and childhood wich together make a picture about what the "refugeechild" means to those who figure in my composition. I have been inspired by discourse, postcolonialism and nationalism. I want to understand why the term "refugeechild", in my sence has a meaning of a duel between a discourse about"children"and"refugees".

    Fifty moves a year: is there an association between joint physical custody and psychosomatic problems in children?2015In: Journal of Epidemiology and Community Health, ISSN 0143-005X, E-ISSN 1470-2738, Vol. 69, no 8, 769-774 p.Article in journal (Refereed)
    Abstract [en]

    Background In many Western countries, an increasing number of children with separated parents have joint physical custody, that is, live equally much in their parents respective homes. In Sweden, joint physical custody is particularly common and concerns between 30% and 40% of the children with separated parents. It has been hypothesised that the frequent moves and lack of stability in parenting may be stressful for these children. Methods We used data from a national classroom survey of all sixth and ninth grade students in Sweden (N=147839) to investigate the association between childrens psychosomatic problems and living arrangements. Children in joint physical custody were compared with those living only or mostly with one parent and in nuclear families. We conducted sex-specific linear regression analyses for z-transformed sum scores of psychosomatic problems and adjusted for age, country of origin as well as childrens satisfaction with material resources and relationships to parents. Clustering by school was accounted for by using a two-level random intercept model. Results Children in joint physical custody suffered from less psychosomatic problems than those living mostly or only with one parent but reported more symptoms than those in nuclear families. Satisfaction with their material resources and parent-child relationships was associated with childrens psychosomatic health but could not explain the differences between children in the different living arrangements. Conclusions Children with non-cohabitant parents experience more psychosomatic problems than those in nuclear families. Those in joint physical custody do however report better psychosomatic health than children living mostly or only with one parent. Longitudinal studies with information on family factors before and after the separation are needed to inform policy of childrens postseparation living arrangements.

    Living in two homes-a Swedish national survey of wellbeing in 12 and 15 year olds with joint physical custody2013In: BMC Public Health, ISSN 1471-2458, Vol. 13Article in journal (Refereed)
    Abstract [en]

    Background

    The practice of joint physical custody, where children spend equal time in each parent’s home after they separate, is increasing in many countries. It is particularly common in Sweden, where this custody arrangement applies to 30 per cent of children with separated parents. The aim of this study was to examine children’s health-related quality of life after parental separation, by comparing children living with both parents in nuclear families to those living in joint physical custody and other forms of domestic arrangements.

    Methods

    Data from a national Swedish classroom study of 164,580 children aged 12 and 15-years-old were analysed by two-level linear regression modelling. Z-scores were used to equalise scales for ten dimensions of wellbeing from the KIDSCREEN-52 and the KIDSCREEN-10 Index and analysed for children in joint physical custody in comparison with children living in nuclear families and mostly or only with one parent.

    Results

    Living in a nuclear family was positively associated with almost all aspects of wellbeing in comparison to children with separated parents. Children in joint physical custody experienced more positive outcomes, in terms of subjective wellbeing, family life and peer relations, than children living mostly or only with one parent. For the 12-year-olds, beta coefficients for moods and emotions ranged from −0.20 to −0.33 and peer relations from −0.11 to −0.20 for children in joint physical custody and living mostly or only with one parent. The corresponding estimates for the 15-year-olds varied from −0.08 to −0.28 and from −0.03 to −0.13 on these subscales. The 15-year-olds in joint physical custody were more likely than the 12-year-olds to report similar wellbeing levels on most outcomes to the children in nuclear families.

    Conclusions

    Children who spent equal time living with both parents after a separation reported better wellbeing than children in predominantly single parent care. This was particularly true for the 15-year-olds, while the reported wellbeing of 12-years-olds was less satisfactory. There is a need for further studies that can account for the pre and post separation context of individual families and the wellbeing of younger age groups in joint physical custody.

    Sverigebilder: En bildanalys av Svenska institutets informationsmaterial2009Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Svenska institutet är en statlig myndighet vars uppdrag är att sprida en positiv och aktuell bild av Sverige. Detta har enligt dem själva blivit allt viktigare i och med globaliseringen. Då världen allt mer homogeniseras blir det viktigare för en nation att vara konkurrenskraftig och visa sin särart för att locka hit handelspartners, investerare, studenter, turister samt arbetskraft.

    Den här uppsatsen diskuterar Svenska institutets arbete med bilden av Sverige och de tankar och strategier som ligger bakom det informationsmaterial de producerar. Med hjälp av bildanalys undersöks filmen Open Skies Open Minds och broschyren Sweden & Swedes som båda ska illustrera det samtida Sverige. Vi har även analyserat intervjuer med projektledaren för filmen Cecilia Sundstrand, producenten för både filmen och broschyren Claes Britton samt Svenska institutets generaldirektör Olle Wästberg. I analysen tar vi stöd av teorier och tankar kring nationalism.

    Denna studie konstaterar att Svenska institutet har en väl utarbetat varumärkesstrategi som ska fungera som en ledstjärna för alla de som arbetar med Sverigerepresentation. Detta för att ge enhetlig Sverigebild och därmed stärka varumärket Sverige. Materialet visar på kulturella stereotyper och de värdeord som Svenska institutet har tagit fram. Ett av huvudresultaten är att materialet anspelar på känslor och värderingar istället för att marknadsföra fysiska platser och produkter.

    Rum för delaktighet: En studie av en skolas möjligheter att skapa förutsättningar för ungdomars delaktighet2002Report (Other academic)
    Abstract [sv]

    Utgångspunkten för denna studie ar ett projekt som startade våren 2001. Syftet med projektet ar att identifiera och belysa möjligheter och hinder för delaktighet for barn och ungdomar i behov av stod i en skola för alia. Denna studie ar en del av detta projekt och inriktad pa att identifiera delaktighet i skolan som rum. Med rum menar vi både den fysiska miljön och de ramar som bildar villkor för skolan. Vi genomförde förstudier i form av deltagande observationer på flera olika skolor för ungdomar mellan 13 och 16 år, och valde sedan ut en skola, i studien kallas den Z-Skolan.

    I Inledning har vi utgått fran delaktighet som begrepp, men också studier av delaktighet i skolan och skolan som ett diskursivt faIt. Vi har sökt svar på våra frågor genom att studera dokument på nationell- och kommunalniva, men främst de dokument som lärarna på Z-Skolan producerat. Vi har arbetat med deltagande observationer i skolans vardag, och vi har intervjuat ungdomar på grundskolan år 8 och 9.

    I första delen av analysen har vi inspirerats av bland annat Grounded Theory och fått fram ternan kring delaktighet. Dessa teman är organisation, möten och lärande. Med dessa teman som utgångspunkt har vi sedan gått vidare i ett andra analyssteg diU: vi använt SOU 2000: 1 och det dynamiska medborgarskapet som utgångspunkt. För att uppnå delaktighet, enligt det dynamiska medborgarskapet, måste deltagande och inflytande men också jämlikhet och insyn vara identifierbara.

    Vi har funnit att delaktighet finns för manga ungdomar i många situationer pa Z-Skolan, men det finns också inslag av utanförskap och ickedelaktighet. Möjlighetema till delaktighet, men också hindren finner vi både inom organisationen och den fysiska miljön, men inte minst genom vuxnas förhållningssatt och respekt mot ungdomarna och deras kultur. Om delaktighet ses som en rättighet eller en praktik för fostran till demokratiska medborgare får det olika konsekvenser för ungdomars skolvardag.

    Den svårfångade delaktigheten i skolan: Ett ungdomsperspektiv på hinder och möjligheter2005Licentiate thesis, monograph (Other academic)
    Abstract [sv]

    Den här avhandlingen handlar om ungdomars erfarenheter och upplevelser av delaktighet i det som enligt skolans mål skall vara ´en skola för alla´. Vi har under tre terminer varit deltagande observatörer och intervjuat ungdomar på en skola (år 6-9) som vi kallar Vegaskolan. Studien beskriver möten i tid och rum mellan olika livsvärldar, mellan ungdomarna sinsemellan, mellan ungdomar och vuxna och mellan vuxna. Här framträder också relationen mellan ungdomar och det innehåll som skolan arbetar med. Dessa möten får konsekvenser för delaktighet och utanförskap, ungdomarnas självbilder, lärandet och vilket stöd som de erbjuds.

    Vår ambition har varit att se delaktighet ur ungdomars perspektiv med syftet att förstå de processer som reser hinder och skapar möjligheter för delaktighet. Vår utgångspunkt har varit ungdomarnas syn på sitt vardagsliv i skolan. De har berättat om sina minnen från förskola och skola, sin nutid och sina tankar om framtiden, gjort val av vad de sett som relevant att delge oss och hur de velat framställa sina erfarenheter. I sina reflektioner har de bidragit med analyser av skolan och det som skett där. De har i jämförelse med skolpersonal i flera avseenden en annorlunda erfarenhet av skolan samt en helhetsbild av sin egen tid där.

    De vuxna kommer bara i mycket begränsad utsträckning till tals i denna studie. De syns genom ungdomarnas och våra beskrivningar av vad de säger och gör. Detta kan tyckas ge en ensidig bild men vi menar att det mesta som skrivs om skolan utgår från ett vuxenperspektiv och att den bilden behöver kompletteras med andra perspektiv.

    Vi har valt att göra fältstudien på en skola, som vi utifrån mötet med ungdomarna och vuxna där upplevde som ”det goda exemplet”. Vi bedömde att vi i denna miljö skulle kunna upptäcka mer av möjligheter till delaktighet, men också vilka hindren är även under relativt goda förhållanden. Avhandlingen har möjliggjorts av skolverket som har finansierat den som projektarbete under tre år.

    Like the worst toothache you've had - How people with rheumatoid arthritis describe and manage pain2017In: Scandinavian Journal of Occupational Therapy, ISSN 1103-8128, E-ISSN 1651-2014, Vol. 24, no 6, 468-476 p.Article in journal (Refereed)
    Abstract [en]

    Background: Rheumatoid arthritis (RA) is a chronic inflammatory disease often associated with disability. Despite new treatments, pain and activity limitations are still present. Objectives: To describe how persons with RA experience and manage pain in their daily life. Methods: Seven semi-structured focus groups (FGs) were conducted and analyzed using content analysis. Results: The analysis revealed four categories: 1) Pain expresses itself in different ways referred to pain as overwhelming, aching or as a feeling of stiffness. 2) Mitigating pain referred to the use of heat, cold, medications and activities as distractions from the pain. 3) Adapting to pain referred to strategies employed as coping mechanisms for the pain, e.g. planning and adjustment of daily activities, and use of assistive devices. 4) Pain in a social context referred to the participants social environment as being both supportive and uncomprehending, the latter causing patients to hide their pain. Conclusions: Pain in RA is experienced in different ways. This emphasizes the multi-professional team to address this spectrum of experiences and to find pain management directed to the individual experience that also include the persons social environment.

    Lectin affinity capillary electrophoresis in glycoform analysis applying the partial filling technique2004In: Journal of chromatography. B, ISSN 1570-0232, Vol. 809, no 2, 323-329 p.Article in journal (Refereed)
    Abstract [en]

    The study of protein glycosylation and its significance in biological interactions is a field of growing interest. This work demonstrates a lectin-based separation of protein glycoforms of α1-acid glycoprotein (AGP or orosomucoid) with capillary electrophoresis. Glycoform analysis was performed with a "partial filling technique" with the lectin Concanavalin A (Con A) as affinity ligand. Con A separated human AGP into two peaks, the first peak included AGP glycoforms without biantennary glycans, and the second peak represented the fraction that had one or more biantennary glycans. The applicability of the method was demonstrated with the analysis of AGP from clinical samples and AGP treated with N-glycosidase F. The AGP separation was also used as a reporter system to estimate the dissociation constant (KD) between Con A and a competing sugar. © 2004 Elsevier B.V. All rights reserved.

    Kolliderande standardavtal2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna uppsats behandlar frågan om kolliderande standardavtal, internationellt benämnt battle of the forms. Problematiken grundas i att två parter i en avtalsförhandling har tillsänt varandra olika standardavtal med motstridiga villkor. Tvist uppkommer sedan oftast när parterna börjat prestera eller till och med fullbordat avtalet. Frågan uppkommer då vilka villkor som skall gälla samt hur denna problematik bör lösas. Eftersom problematiken är sparsamt utredd i svensk rätt har vi valt att studera tre nationella och tre internationella rättskällor och regelverk för att söka ledning i frågan. Utifrån det vi har kommit fram till kan det påpekas att en betydande majoritet av de rättskällor och regelverk vi har undersökt har frångått att lösa problematiken med hjälp av den klassiska synen på avtal samt anbud och accept. Syftet med uppsatsen har varit att ge läsaren en helhetsbild av problematiken med kolliderande standardavtal samt visa i vilken riktning utvecklingen på området tenderar att gå. Efter att ha utrett de olika rättskällorna kan vi fastslå att the knock-out rule torde vara den lösningsmodell som domstolarna generellt föredrar att tillämpa.

    A Proof-of-Concept Implementation of a Non-linear Video Player for HTTP-based Adaptive Streaming2013Independent thesis Basic level (university diploma), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    Video consumption on the Internet has been growing over the last decade and is expected to continue to increase. Video streaming is a widely used approach to viewing video on the Internet, which allows users to watch the video while it is being downloaded. Adaptive streaming is a video streaming technique that allows the player to change the downloading video’s bit rate depending on the user’s available bandwidth.

    Another approach to a more personal viewing experience is non-linear videos. These videos can be played in a non-sequential order. For example, a viewer can be given the choice of what ending to watch in a movie, or the path through an exhibition.

    This thesis will present the design and implementation of a novel structure for non-linear video. This structure is used by a video player for downloading and viewing an adaptive video intended for non-linear viewing, stored at some server. Media creators will also have an easier time to both visualize and create uniform video experiences.

    This thesis presents modifications to Adobe’s Open Source Media Framework and Strobe Media Playback which allow playing non-linear video.

    Automated Setup of Display Protocols2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Radiologists' workload has been steadily increasing for decades. As digital technology matures it improves the workflow for radiology departments and decreases the time necessary to examine patients. Computer systems are widely used in health care and are for example used to view radiology images. To simplify this, display protocols based on examination data are used to automatically create a layout and hang images for the user. To cover a wide variety of examinations hundreds of protocols must be created, which is a time-consuming task and the system can still fail to hang series if strict requirements on the protocols are not met. To remove the need for this manual step we propose to use machine learning based on past manually corrected presentations. The classifiers are trained on the metadata in the examination and how the radiologist preferred to hang the series. The chosen approach was to create classifiers for different layout rules and then use these predictions in an algorithm for assigning series types to individual image slots according to categories based on metadata, similar to how display protocol works. The resulting presentations shows that the system is able to learn, but must increase its prediction accuracy if it is to be used commercially. Analyses of the different parts show that increased accuracy in early steps should improve overall success.

    Eye-movement-controlled transform image coders2003In: Signal processing. Image communication, ISSN 0923-5965, Vol. 18, no 2, 115-125 p.Article in journal (Refereed)
    Abstract [en]

    An image-coding scheme which combines transform coding with a human visual system (HVS) model is described. The system includes an eye tracker to pick up the point of regard of a single viewer. One can then utilize that the acuity of the HVS is less in the peripheral vision than in the central part of the visual field. A model of the decreasing acuity of the HVS, which can be applied to a wide class of transform coders is described. Such a coding system has large potential for data compression. In this paper, we have incorporated the model into four different transform coders, one from each of the main classes of transform coders. Two of the coders are block-based decomposition schemes, the discrete cosine transform-based JPEG coder and a lapped transform scheme. The two others are subband-based decomposition schemes, a wavelet based and a wavelet packet-based scheme. © 2002 Elsevier Science B.V. All rights reserved.

    Rätt till skadestånd enligt upphandlingsreglera: utformning av beviskraven för ett rättssäkert och ekonomiskt effektivt upphandlingsförfarande2005Independent thesis Advanced level (degree of Magister), 10 points / 15 hpStudent thesis
    Abstract [en]

    Rules for damages that are effective are important to create legal security and a public procurement that fulfil economic effectivity. Those rules are effectivly created for example when the demand of evidence is possible for the damaged supplier to fulfil. Yet the rules cannot be too low without leading to an uncertain procurement for the public purchaser. Thus one have to balance the interests of a public purchaser against the interests of a damaged supplier. This balance leads to a public procurement involving rules of damages where the public purchaser cannot escape duty of damages just because the demand of evidence is too hard to fulfil.

    Hur RFID kan påverka logistisk effektivitet: en studie av den svenska dagligvarubranschen2006Independent thesis Basic level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis is to study how the use of RFID and EPC would affect the Swedish food retail supply chain. This was done by mapping the flow of five different products in the supply chain at activity level. During this work, five manufacturers, two distribution centres and two retail stores were visited and carefully studied. These visits resulted in a flowchart for each company describing the product flow, with particular attention to the use of barcodes. The flowcharts were then used to create scenarios for each company, describing how the flow would change when using RFID-technology. The current flow for each company was then compared with its RFID scenario and analysed to see how logistic efficiency would be affected by the use of RFID-technology.

    The result of the study shows that all companies in the food retail supply chain would benefit from an implementation of RFID-technology. When comparing companies with a high usage of barcodes with companies where barcodes are little used, the conclusion can be drawn that both groups would experience improvements in different areas of logistic efficiency, but not necessarily to the same extent.

    When considering the drawbacks of using RFID, the greatest disadvantages are the large investments and costs of implementing the technology. The largest costs arise in modification of business systems and for hardware investments needed to utilize the technology.

    Apart from theses costs and investments, several positive changes in time consumption and traceability could be found. RFID/EPC makes it possible to replace manual checks with automatic ones, resulting in less time consumption and reduced staff throughout the supply chain. Furthermore, the possibility to trace every case and pallet results in more efficient and less expensive of product returns and recalls.

    Automation of a Data Analysis Pipeline for High-content Screening Data2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    High-content screening is a part of the drug discovery pipeline dealing with the identification of substances that affect cells in a desired manner. Biological assays with a large set of compounds are developed and screened and the output is generated with a multidimensional structure. Data analysis is performed manually by an expert with a set of tools and this is considered to be too time consuming and unmanageable when the amount of data grows large. This thesis therefore investigates and proposes a way of automating the data analysis phase through a set of machine learning algorithms. The resulting implementation is a cloud based application that can support the user with the selection of which features that are relevant for further analysis. It also provides techniques for automated processing of the dataset and training of classification models which can be utilised for predicting sample labels. An investigation of the workflow for analysing data was conducted before this thesis. It resulted in a pipeline that maps the different tools and software to what goal they fulfil and which purpose they have for the user. This pipeline was then compared with a similar pipeline but with the implemented application included. This comparison demonstrates clear advantages in contrast to previous methodologies in that the application will provide support to work in a more automated way of performing data analysis.

    Effekten av förändrade kreditbetyg: En studie på den svenska aktiemarknaden2008Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [sv]

    Bakgrund: Det primära syftet med ett kreditbetyg är att tillhandahålla information till kreditgivare och investerare angående ett företags återbetalningsförmåga. Kreditbetyget baseras både på publik och privat information och bör därför vid publicering påverka priserna på både kreditmarknaden samt aktiemarknaden under förutsättning att dessa är semieffektiva marknader.

    Syfte: Syftet är att studera hur aktiekurserna för samtliga företag på Stockholmsbörsen, som erhåller kreditbetyg från S&P, påverkas vid en förändring av företagets kreditbetyg samt outlook.

    Genomförande: Uppsatsens syfte besvaras genom att undersöka aktieavkastningen i samband med publiceringen av ett förändrat kreditbetyg. Vi har använt oss utav en event study för att isolera och testa eventuell abnorm avkastning.

    Slutsatser: Av de totala antal tester som vi har utfört finner vi att endast en bråkdel av dessa är signifikanta på 10 % eller lägre. För att med säkerhet fastställa att ett förändrat kreditbetyg påverkar aktieavkastning hade en signifikant abnorm avkastning på 1 % nivå önskats för en majoritet av testerna. Således finner vi inte några starka bevis för att en förändring av kreditbetyg påverkar aktiekurser på den svenska marknaden. Detta indikerar att de svenska företagen betalar för en tjänst som aktiemarknaden inte värdesätter.

    Health-Related Quality of Life In Patients With Adrenal Insufficiency Receiving Plenadren Compared With Immediate-Release Hydrocortisone.2015In: Value in Health, ISSN 1098-3015, E-ISSN 1524-4733, Vol. 18, no 7, A616- p.Article in journal (Refereed)
    Abstract [en]

    Background

    Previous studies in patients with primary adrenal insufficiency (PAI) on conventional replacement therapy suggest decreased health-related quality of life (HRQoL), and that patients report more frequently fatigue, increased anxiety and inability to work compared to background population.

    Objectives

    To study self-reported health status with EQ-5D in patients with PAI. Patients treated with Plenadren (modified-release hydrocortisone) were compared with patients treated with immediate release hydrocortisone (IRHC) replacement therapy.

    Methods

    This was a cross-sectional, multi-centre, non-interventional survey of patients with PAI receiving Plenadren or immediate release hydrocortisone (IRHC) replacement.

    Subjects

    One hundred thirty-four adult patients with PAI of whom 36 (19 females [53%]) were treated with Plenadren and 98 (77 females [79%]) were treated with IRHC, were included.

    MAIN OUTCOME MEASURE

    HRQoL described by the EQ-5D, a generic preference-based measure of health.

    RESULTS

    Patients on Plenadren and on IRHC had a mean ± SD age of 53.1 ± 12.7 years and 48.0 ± 13.1 years, respectively (P=0.043). The majority of the patients were diagnosed more than 5 years ago (69%). The mean ± SD daily Plenadren and IRHC doses were 27.0 ± 6.8 mg and 26.6 ± 10.9 mg, respectively (P=0.807). 47% of the Plenadren patients had been receiving Plenadren and 82% of the IRHC patients had been receiving IRHC for more than 3 years. Patients receiving Plenadren had better HRQoL measured by the EQ-5D questionnaire compared to patients replaced with IRHC (0.76 ± 0.18 vs 0.68 ± 0.18, respectively [P=0.040]).

    CONCLUSIONS

    Replacement therapy with Plenadren in patients with PAI confers measurable benefit on HRQoL relative to IRHC as estimated by the EQ-5D questionnaire, and may therefore be advantageous when compared to IRHC substitution.

    The domestication effects on social support in chickens (Gallus gallus)2012Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    When animals are stressed they use a trait called social support to alleviate their stress responses. With domestication many traits from the ancestor red junglefowl have changed in the domesticated breed white leghorn. White leghorns are bred to be able to live in large groups where it becomes hard to recognize every chicken. They are therefore not as dependent of familiar stimuli birds for social support as red junglefowl. Our hypotheses were that red jungle males would be more interested in unfamiliar stimuli birds than white leghorn male before stress due to their territoriality. We tested total 56 chickens in an open field test. The test arena was divided in three zones and the time the focal birds spent in each zone was recorded. The focal bird was recorded in 300 seconds before being stressed by being suspended in a net and then recorded again in 300 seconds. The results showed that social support and social behaviour differs between females and males for both breeds. No significant differences were found between the breeds. There was a tendency for significant of breed (P=0.08) effects in the central zone unstressed. The two interactions before stressed between breed and sex, central zone (P<0.01) and unfamiliar zone (P<0.01) had significant effects. We observed fights between white leghorn males and familiar stimuli. Waltzing did also occur in red jungle males in front of unfamiliar. In conclusion, numeric differences can be seen but not large enough to be significant and our hypotheses are not confirmed.

    Business Intelligence: En inblick i relationen mellan tillgänglig data och hur den används inom marknadsföring2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Today there are great opportunities to gather data related to a company’s customers, processes, goods and services no matter what line of business they are in. If you have resources and are interested there are endless opportunities to gather data, analyze it and then use it to develop and optimize the company. The purpose of this study is to examine challenges when it comes to the use of stored data in business intelligence and to look into which factors that affects the process of turning stored data into usable information that can be used when making marketing decisions. I have chosen to focus on the organizational aspects and connections between business intelligence and marketing with the help of a case study. The study uses a qualitative research approach and the empirical data consists of qualitative semi-structured interviews and data collection in terms of clustering. All empirical data has been gathered from a large Swedish IT-company. A thematic analysis of gathered empirical data leads to a result showing that there are a number of challenges when it comes to using stored data in business intelligence at a large Swedish IT-company. These challenges consist of; unclear visions and goals, economic priorities, unclear terminology and the approach to organizational structures. Results from the study also points out several factors that lies behind why all available data at a large Swedish IT-company is not used to its fullest potential within marketing. These factors are; old habits and adaptability to new technology, management and communication and finally time constraints and knowledge management.

    I have been able to see with this study that it takes a fundamental purpose to analyze something and that it is not certain that such a purpose always exists. It is hard to transform data into valuable information and also to optimize decision making if this purpose does not exist. There are many studies which demonstrate either the awareness by companies of the problems facing them in dealing with high volumes of data and/or their admission that they have a long way to cope with these volumes. I have with this study been able to see that this research problem may be useful and that it is highly relevant within a large Swedish IT-company.

    För- och nackdelar med varuförsörjning via lokala mikroterminaler: En studie av köpcentrum i Linköping och Norrköping2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    I takt med att världens städer blir allt mer tätbefolkade ökar behovet av varor i städerna. Varutransporter inom tätbebyggda områden för med sig många problem, så som luftföroreningar, buller och trängsel, men är vitala för städernas överlevnad. En av åtgärderna som föreslås i litteraturen för att minska dessa problem kallas lokal mikroterminal (LMT), som är en logistisk anläggning i utkanten av ett tätbebyggt område där varor konsolideras innan de levereras till mottagare inom det tätbebyggda området. Lokala mikroter- minaler har stor potential till att minska den miljöpåverkan som varutrans- porter i tätbebyggda områden för med sig, men de är ändå sällsynta.

    Studiens syfte var att ”identifiera potentiella för- och nackdelar, ur ett ekonomiskt, ekologiskt och socialt perspektiv, med att styra varuflödet till köp- centrum i Linköping och Norrköping via lokala mikroterminaler”. Efter lit- teratursökningen stod det klart att ur de ekologiska och sociala hållbarhets- dimensionerna hade flera fördelar med LMT:er identifierats och uppmätts. Fördelarna i dessa två dimensioner uppnås genom att varutransporten utförs effektivare om en lokal mikroterminal används. Eftersom LMT:n även har en driftskostnad så har många LMT:er dock lagts ner på grund av att de blev för dyra. Studien fokuserades därför på det ekonomiska perspektivet. Ifall fler möjliga ekonomiska fördelar med LMT:er identifierades skulle det öka sannolikheten att fler lönsamma LMT:er kan införas.

    Valet av aktörsperspektiv preciserades ytterligare genom att studien fo- kuserades på butiker och hur de påverkas av ett införande av en LMT. Den mest centrala utgångspunkten var hur personalens butikslogistiska (Kotzab & Teller, 2005) arbetsuppgifter påverkade deras möjlighet att erbjuda så bra service som möjligt och ifall en LMT kan motverka eventuella butikslogis- tiska problem hos butikerna. De butikslogistiska aktiviteter som undersök- tes var leveransmottagning, uppackning, prismärkning, larmning samt skräp- hantering/återvinning. Dessutom undersöktes butikernas behov av ett större lagringsutrymme. Studiens frågeställningar besvarades med hjälp av 51 semi- strukturerade intervjuer hos butiker i köpcentrum i Linköping och Norrkö- ping, samt till en viss del med hjälp av litteraturen.

    Den största potentialen till ekonomiska fördelar för butikerna identifiera- des som möjligheten till att få alla leveranser tidigt under dagen och möjlig- heten till att kunna utnyttja LMT:n som en lagringspunkt. 75 % av butikerna angav antingen butikslogistiska aktiviteter eller lagring som ett problem och därmed bör en stor andel av butikerna ha någon form av intresse för vad en LMT kan erbjuda. För att uppnå dessa ekonomiska fördelar är det därför viktigt att en LMT kan erbjuda ett stort antal tilläggstjänster.

    Risk analysis review2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The risk analysis process is the foundation of creating secure systems. An accurate and well defined risk analysis will therefore be a big help for any company, indicating what resources are needed and where they should be put to use. It can be difficult to know which risk analysis methodology to use given a set of parameters such as available resources, time, money etc. In this review we will introduce several different risk analysis methodologies and classify them using our risk analysis classification system. Our classification points out some of the pros and cons for each method, making it easier to choose the one best suited for a specific scenario. We will also connect the presented methods with real-world usage of said methods. To do this we have conducted interviews with IT-security experts at several major companies and we will present previous documented usage of risk analysis methods. Larger companies tend to develop their own methods for risk analysis, and smaller companies that do not have enough time or resources to develop their own methods are more likely to use already existing methods. With that said we believe that anyone that works with risk analysis could have use of our review.

    Förändringsprocesser i acceptance and commitment therapy för personer med hörselnedsättning: - en randomiserad kontrollerad studie2014Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    I Sverige beräknas 17 % av befolkningen ha en hörselnedsättning, vilket innebär att det är den vanligaste sensoriska funktionsnedsättningen. Idag finns det en mängd studier som visar att hörselnedsättning är relaterat till sämre psykisk hälsa. Acceptans av sin hörselnedsättning har visat sig vara positivt för hörselnedsatta och samvarierar med hjälpsökande. Acceptance and commitment therapy (ACT) är en transdiagnostisk behandling där psykopatologi antas bero på en hög grad av upplevelsemässigt undvikande och fusion med tankar. Målet i ACT är att öka psykologisk flexibilitet där acceptans är en betydande komponent. Denna explorativa studie undersökte förändringsprocesser i ACT för personer med hörselnedsättning där utfallet var känslomässig och social anpassning för hörselnedsättningen (HHIE-S). De förändringsprocesser som prövades var acceptans (HAQ), som tidigare visat på medierande effekt för ACT, samt två alternativa förändringsprocesser; self-efficacy (HSE-4) och upplevd stress (PSS-4). Behandlingen bestod av åtta internetadministrerade moduler givna med behandlarstöd där veckovisa mätningar av förändringsprocesser och utfall användes. Studiens resultat visar att behandlingsgruppen upplevde marginellt signifikant mindre problem med känslomässig och social anpassning för hörselnedsättningen (HHIE-S). Studiens resultat pekar på att hörselrelaterad acceptans (HAQ) och self- efficacy (HSE-4) medierar behandlingens effekt på deltagarnas känslomässiga och sociala anpassning för hörselnedsättning (HHIE-S). Således tillför denna studie ytterligare belägg för acceptans som förändringsprocess i ACT. Även self-efficacy kan vara en intressant mediator att beakta i fortsatt forskning.
