    MULTIWAVELENGTH MONITORING OF THE ENIGMATIC NARROW-LINE SEYFERT 1 PMN J0948+0022 IN 2009 MARCH-JULY2009In: Astrophysical Journal, ISSN 0004-637X, E-ISSN 1538-4357, Vol. 707, no 1, p. 727-737Article in journal (Refereed)
    Abstract [en]

    Following the recent discovery of gamma rays from the radio-loud narrow-line Seyfert 1 galaxy PMN J0948+0022 (z = 0.5846), we started a multiwavelength campaign from radio to gamma rays, which was carried out between the end of 2009 March and the beginning of July. The source displayed activity at all the observed wavelengths: a general decreasing trend from optical to gamma-ray frequencies was followed by an increase of radio emission after less than two months from the peak of the gamma-ray emission. The largest flux change, about a factor of about 4, occurred in the X-ray band. The smallest was at ultraviolet and near-infrared frequencies, where the rate of the detected photons dropped by a factor 1.6-1.9. At optical wavelengths, where the sampling rate was the highest, it was possible to observe day scale variability, with flux variations up to a factor of about 3. The behavior of PMN J0948+0022 observed in this campaign and the calculated power carried out by its jet in the form of protons, electrons, radiation, and magnetic field are quite similar to that of blazars, specifically of flat-spectrum radio quasars. These results confirm the idea that radio-loud narrow-line Seyfert 1 galaxies host relativistic jets with power similar to that of average blazars.

    FERMI LAT DISCOVERY OF EXTENDED GAMMA-RAY EMISSION IN THE DIRECTION OF SUPERNOVA REMNANT W51C2009In: Astrophysical Journal Letters, ISSN 2041-8205, Vol. 706, no 1, p. L1-L6Article in journal (Refereed)
    Abstract [en]

    The discovery of bright gamma-ray emission coincident with supernova remnant (SNR) W51C is reported using the Large Area Telescope (LAT) onboard the Fermi Gamma-ray Space Telescope. W51C is a middle-aged remnant (similar to 10(4) yr) with intense radio synchrotron emission in its shell and known to be interacting with a molecular cloud. The gamma-ray emission is spatially extended, broadly consistent with the radio and X-ray extent of SNR W51C. The energy spectrum in the 0.2-50 GeV band exhibits steepening toward high energies. The luminosity is greater than 1 x 10(36) erg s(-1) given the distance constraint of D > 5.5 kpc, which makes this object one of the most luminous gamma-ray sources in our Galaxy. The observed gamma-rays can be explained reasonably by a combination of efficient acceleration of nuclear cosmic rays at supernova shocks and shock-cloud interactions. The decay of neutral pi mesons produced in hadronic collisions provides a plausible explanation for the gamma-ray emission. The product of the average gas density and the total energy content of the accelerated protons amounts to (n) over bar W-H(p) similar or equal to 5 x 10(51) (D/6 kpc)(2) erg cm(-3). Electron density constraints from the radio and X-ray bands render it difficult to explain the LAT signal as due to inverse Compton scattering. The Fermi LAT source coincident with SNR W51C sheds new light on the origin of Galactic cosmic rays.

    RADIO-LOUD NARROW-LINE SEYFERT 1 AS A NEW CLASS OF GAMMA-RAY ACTIVE GALACTIC NUCLEI2009In: Astrophysical Journal Letters, ISSN 2041-8205, Vol. 707, no 2, p. L142-L147Article in journal (Refereed)
    Abstract [en]

    We report the discovery with Fermi/LAT of gamma-ray emission from three radio-loud narrow-line Seyfert 1 galaxies: PKS 1502+036 (z = 0.409), 1H 0323+342 (z = 0.061), and PKS 2004-447 (z = 0.24). In addition to PMN J0948+0022 (z = 0.585), the first source of this type to be detected in gamma rays, they may form an emerging new class of gamma-ray active galactic nuclei (AGNs). These findings can have strong implications on our knowledge about relativistic jets and the unified model of the AGN.

    Fermi Observations of High-Energy Gamma-Ray Emission from GRB 080916C2009In: Science, ISSN 0036-8075, E-ISSN 1095-9203, Vol. 323, no 5922, p. 1688-1693Article in journal (Refereed)
    Abstract [en]

    Gamma-ray bursts (GRBs) are highly energetic explosions signaling the death of massive stars in distant galaxies. The Gamma-ray Burst Monitor and Large Area Telescope onboard the Fermi Observatory together record GRBs over a broad energy range spanning about 7 decades of gamma-ray energy. In September 2008, Fermi observed the exceptionally luminous GRB 080916C, with the largest apparent energy release yet measured. The high-energy gamma rays are observed to start later and persist longer than the lower energy photons. A simple spectral form fits the entire GRB spectrum, providing strong constraints on emission models. The known distance of the burst enables placing lower limits on the bulk Lorentz factor of the outflow and on the quantum gravity mass.

    FERMI OBSERVATIONS OF HIGH-ENERGY GAMMA-RAY EMISSION FROM GRB 080825C2009In: Astrophysical Journal, ISSN 0004-637X, E-ISSN 1538-4357, Vol. 707, no 1, p. 580-592Article in journal (Refereed)
    Abstract [en]

    The Fermi Gamma-ray Space Telescope has opened a new high-energy window in the study of gamma-ray bursts (GRBs). Here we present a thorough analysis of GRB 080825C, which triggered the Fermi Gamma-ray Burst Monitor (GBM), and was the first firm detection of a GRB by the Fermi Large Area Telescope (LAT). We discuss the LAT event selections, background estimation, significance calculations, and localization for Fermi GRBs in general and GRB 080825C in particular. We show the results of temporal and time-resolved spectral analysis of the GBM and LAT data. We also present some theoretical interpretation of GRB 080825C observations as well as some common features observed in other LAT GRBs.

    PULSED GAMMA RAYS FROM THE MILLISECOND PULSAR J0030+0451 WITH THE FERMI LARGE AREA TELESCOPE2009In: Astrophysical Journal, ISSN 0004-637X, E-ISSN 1538-4357, Vol. 699, no 2, p. 1171-1177Article in journal (Refereed)
    Abstract [en]

    We report the discovery of gamma-ray pulsations from the nearby isolated millisecond pulsar (MSP) PSR J0030+0451 with the Large Area Telescope on the Fermi Gamma-ray Space Telescope (formerly GLAST). This discovery makes PSR J0030+0451 the second MSP to be detected in gamma rays after PSR J0218+4232, observed by the EGRET instrument on the Compton Gamma-Ray Observatory. The spin-down power (E) over dot = 3.5 x 10(33) erg s(-1) is an order of magnitude lower than the empirical lower bound of previously known gamma-ray pulsars. The emission profile is characterized by two narrow peaks, 0.07 +/- 0.01 and 0.08 +/- 0.02 wide, respectively, separated by 0.44 +/- 0.02 in phase. The first gamma-ray peak falls 0.15 +/- 0.01 after the main radio peak. The pulse shape is similar to that of the "normal" gamma-ray pulsars. An exponentially cutoff power-law fit of the emission spectrum leads to an integral photon flux above 100 MeV of (6.76 +/- 1.05 +/- 1.35) x 10(-8) cm(-2) s(-1) with cutoff energy (1.7 +/- 0.4 +/- 0.5) GeV. Based on its parallax distance of (300 +/- 90) pc, we obtain a gamma-ray efficiency L-gamma/E similar or equal to 15% for the conversion of spin-down energy rate into gamma-ray radiation, assuming isotropic emission.

    FERMI/LARGE AREA TELESCOPE DISCOVERY OF GAMMA-RAY EMISSION FROM THE FLAT-SPECTRUM RADIO QUASAR PKS 1454-3542009In: Astrophysical Journal, ISSN 0004-637X, E-ISSN 1538-4357, Vol. 697, no 1, p. 934-941Article in journal (Refereed)
    Abstract [en]

    We report the discovery by the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope of high-energy gamma-ray (GeV) emission from the flat-spectrum radio quasar PKS 1454-354 (z = 1.424). On 2008 September 4, the source rose to a peak flux of (3.5 +/- 0.7) x 10(-6) ph cm(-2) s(-1) (E > 100 MeV) on a timescale of hours and then slowly dropped over the following 2 days. No significant spectral changes occurred during the flare. Fermi/LAT observations also showed that PKS 1454-354 is the most probable counterpart of the unidentified EGRET source 3EG J1500-3509. Multiwavelength measurements performed during the following days (7 September with Swift; 6-7 September with the ground-based optical telescope Automated Telescope for Optical Monitoring; 13 September with the Australia Telescope Compact Array) resulted in radio, optical, UV, and X-ray fluxes greater than archival data, confirming the activity of PKS 1454-354.

    FERMI LARGE AREA TELESCOPE OBSERVATIONS OF THE VELA PULSAR2009In: Astrophysical Journal, ISSN 0004-637X, E-ISSN 1538-4357, Vol. 696, no 2, p. 1084-1093Article in journal (Refereed)
    Abstract [en]

    The Vela pulsar is the brightest persistent source in the GeV sky and thus is the traditional first target for new gamma-ray observatories. We report here on initial Fermi Large Area Telescope observations during verification phase pointed exposure and early sky survey scanning. We have used the Vela signal to verify Fermi timing and angular resolution. The high-quality pulse profile, with some 32,400 pulsed photons at E >= 0.03 GeV, shows new features, including pulse structure as fine as 0.3 ms and a distinct third peak, which shifts in phase with energy. We examine the high-energy behavior of the pulsed emission; initial spectra suggest a phase-averaged power-law index of Gamma = 1.51(-0.04)(+0.05) with an exponential cutoff at E-c = 2.9 +/- 0.1 GeV. Spectral fits with generalized cutoffs of the form e(-(E/Ec)b) require b <= 1, which is inconsistent with magnetic pair attenuation, and thus favor outer-magnetosphere emission models. Finally, we report on upper limits to any unpulsed component, as might be associated with a surrounding pulsar wind nebula.

    The Fermi Gamma-Ray Space Telescope Discovers the Pulsar in the Young Galactic Supernova Remnant CTA 12008In: Science, ISSN 0036-8075, E-ISSN 1095-9203, Vol. 322, no 5905, p. 1218-1221Article in journal (Refereed)
    Abstract [en]

    Energetic young pulsars and expanding blast waves [ supernova remnants (SNRs)] are the most visible remains after massive stars, ending their lives, explode in core-collapse supernovae. The Fermi Gamma- Ray Space Telescope has unveiled a radio quiet pulsar located near the center of the compact synchrotron nebula inside the supernova remnant CTA 1. The pulsar, discovered through its gamma- ray pulsations, has a period of 316.86 milliseconds and a period derivative of 3.614 x 10(-13) seconds per second. Its characteristic age of 10(4) years is comparable to that estimated for the SNR. We speculate that most unidentified Galactic gamma- ray sources associated with star- forming regions and SNRs are such young pulsars.

    DISCOVERY OF PULSED gamma-RAYS FROM THE YOUNG RADIO PULSAR PSR J1028-5819 WITH THE FERMI LARGE AREA TELESCOPE2009In: Astrophysical Journal Letters, ISSN 2041-8205, Vol. 695, no 1, p. L72-L77Article in journal (Refereed)
    Abstract [en]

    Radio pulsar PSR J1028-5819 was recently discovered in a high-frequency search (at 3.1 GHz) in the error circle of the Energetic Gamma-Ray Experiment Telescope (EGRET) source 3EG J1027-5817. The spin-down power of this young pulsar is great enough to make it very likely the counterpart for the EGRET source. We report here the discovery of gamma-ray pulsations from PSR J1028-5819 in early observations by the Large Area Telescope (LAT) on the Fermi Gamma-Ray Space Telescope. The gamma-ray light curve shows two sharp peaks having phase separation of 0.460 +/- 0.004, trailing the very narrow radio pulse by 0.200 +/- 0.003 in phase, very similar to that of other known gamma-ray pulsars. The measured gamma-ray flux gives an efficiency for the pulsar of similar to 10-20% (for outer magnetosphere beam models). No evidence of a surrounding pulsar wind nebula is seen in the current Fermi data but limits on associated emission are weak because the source lies in a crowded region with high background emission. However, the improved angular resolution afforded by the LAT enables the disentanglement of the previous COS-B and EGRET source detections into at least two distinct sources, one of which is now identified as PSR J1028-5819.

    Tidig insulinbehandling för typ II diabetiker2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Diabetes mellitus är en av de vanligaste endokrina sjukdomarna och de vanligaste formerna är typ I och typ II. Idag har ca 350 000 personer i Sverige diabetes och av dessa har 85-90% diabetes typ II. Typ II diabetes börjar med insulinresistens och så småningom blir det avtagande funktion av β- cellerna vilket leder till nedsatt insulinkänslighet och främsta orsakerna till typ II diabetes är övervikt och fetma. Det finns olika behandlingsrekommendationer för att behandla typ II diabetiker för att minska att sena komplikationer uppstår. Främst genom livsstilsförändringar som kost och fysisk aktivitet, men då dessa inte räcker till kan perorala läkemedel komma i efterhand och om inte det heller ger tillräcklig effekt kan insulinbehandling sättas in. Ca 50 % av typ II diabetiker får insulin efter 10 års sjukdom.

    Syftet med arbetet är att undersöka om det finns en god implikation av att sätta in insulin tidigare än det som redan är rekommenderat.

    Denna litteraturstudie är baserad på artiklar hämtade från databasen PubMed. Sammanlagt har fem randomiserade kontrollerade studier granskats.

    Resultaten visar att en HbA1c-sänkning med ca 1,5 - 2,0 % kan erhållas samt också en bibehållen β- cellfunktion vid insättning av insulin. Insulinbehandlingen bör sättas in så snart HbA1c går över 7,5 % istället för att vänta en viss tid. Den kan sättas in hos behandlingsnaiva personer med framträdande symtom eftersom insulin fortfarande sänker HbA1c och det finns inget som tyder på att insulin inte kan sättas in tidigare än det som är rekommenderat.

    Slutsatsen som dras är att stödja intensiv behandling som gör att HbA1c hålls på en så låg nivå det är möjligt och när målvärden för HbA1c inte kan hållas kan insulin med fördel sättas in hos typ II diabetiker som behandlats med perorala antidiabetika.

    Gränssnittets betydelse i främjandet av kognitiv bearbetning: En undersökning om praktisk utnyttjande av designprinciper i skapandet av webbgränssnitt2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Många webbgränssnitt idag misslyckas med att möta användarnas behov och blir därför bristfälliga gällande användarvänligheten. Detta leder till att användarna begår stora misstag och anstränger sig vid användningen av webbaserade system. Visuell design och struktur i ett gränssnitt spelar en stor roll i hur användarna förstår sig på och tolkar ett gränssnitt då de avser hur olika beteenden och information kommuniceras till användarna. I denna studie undersöks hur visuell design, struktur och användbarhet i ett gränssnitt underlättar användarnas kognitiva bearbetning av information vid utförande av komplexa uppgifter. Studien har utförts genom ett uppdrag för Ahltorpmedia AB, som skapar lösningar för bl.a. webbplatser, webbaserade system och e-handel. Uppdraget har varit att förbättra en av deras egen utvecklade tjänst Nuhet som är bristfällig gällande områdena ovan.

     

    Först har en heuristisk utvärdering av Nuhets befintliga gränssnitt samt sju intervjuer med tjänstens befintliga- och potentiella användare inom huvudområdena visuell design, struktur och kognitiv bearbetning av information gjorts. Resultaten från intervjuerna och utvärderingen har använts för att bilda en persona varefter fokusområden för prototyparbetet har skapats. Sedan har en prototyp på Nuhets nya utseende och en ny funktionalitet skapats. Designprinciper för användbarhet samt gestaltlagar har nyttjats i skapandet av Nuhets nya gränssnitt.

     

    Utifrån de metoder som har genomförts i detta examensarbete har det framkommit att det beror på flera faktorer gällande hur användarnas kognitiva bearbetning av information underlättas med hjälp av visuell design, struktur och användarvänlighet. Dessa är då en bra struktur, gruppering och organisering av innehåll i ett gränssnitt. Dessutom är det tydliga kontraster, bra färgval och standardisering som underlättar den.

    Attefallshus som komplementbostadshus: Drömhus eller mardröm?2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den 2 juli 2014 blev det enligt lag tillåtet för en- och tvåbostadshusägare att uppföra en bygglovsbefriad komplementbyggnad på max 25 kvadratmeter på den egna fastigheten. Rapporten undersöker vilket genomslag lagändringen har haft i Stor-Stockholm, Stor-Göteborg och Stor-Malmö. Undersökningen visar att lagändringen ännu inte har haft något stort genomslag. I rapporten undersöks även en utvald del av marknadsaktörers utbud av attefallshus avsett som komplementbostadshus. 

    Ett attefallshus utformas med miljövänligt hållbara material och inspireras av Vitruvius tre principer för god arkitektur. Huset konstrueras med avsikt att uppfylla kraven som ställs i PBL, PBF, BBR och EKS. Målet med de framtagna bygghandlingarna är att få startbesked från byggnadsnämnden i Växjö.

    Abstract [en]

    Abstract

    This study examines the approaches used by teachers to motivate their pupils to read and investigates what underlying factors they claim may explain why pupils feel no motivation to read. The study was conducted from the perspective of five active teachers, with data collection by interview. The study found that the interviewed teachers use psychological support as well as structured teaching such as reading aloud and book talks, along with a varied range of methods, to motivate their pupils to read. The interviewed teachers state that there must be motivation if a pupil is to become a good reader, and it is very important that pupils receive support from adults, both at home and in school. According to the teachers, pupils lose motivation if they are given texts that are too difficult for them to understand, or if other stimuli motivate them more than reading does. The attitude of parents or guardians to reading is also emphasized as significant for motivation, and hence for pupils’ reading development.

    Doctors' and nurses' views on patient care for type 2 diabetes: an interview study in primary health care in Oman2013In: Primary Health Care Research and Development, ISSN 1463-4236, E-ISSN 1477-1128, Vol. 14, no 3, p. 258-269Article in journal (Refereed)
    Abstract [en]

    Aim: This study aimed at exploring the experiences of primary health-care providers of their encounters with patients with type 2 diabetes, and their preferences and suggestions for future improvement of diabetes care. Background: Barriers to good diabetes care could be related to problems from health-care providers' side, patients' side or the healthcare system of the country. Treatment of patients with type 2 diabetes has become a huge challenge in Oman, where the prevalence has increased to high levels. Method: Semi-structured interviews were conducted with 26 health-care professionals, 19 doctors and seven nurses, who worked in primary health care in Oman. Qualitative content analysis was applied. Findings: Organizational barriers and barriers related to patients and healthcare providers were identified. These included workload and lack of teamwork approach. Poor patients' management adherence and influence of culture on their attitudes towards illness were identified. From the providers' side, language barriers, providers' frustration and aggressive attitudes towards the patients were reflected. Decreasing the workload, availability of competent teams with diabetes specialist nurses and continuity of care were suggested. Furthermore, changing professional behaviours towards a more patient-centred approach and need for health education to the patients, especially on self-management, were addressed. Appropriate training for health-care providers in communication skills with emphasis on self-care education and individualization of care according to each patient's needs are important for improvement of diabetes care in Oman.

    Binokulärseende hos elitidrottare: En studie om djupseende, ackommodationsfacilitet och vergensfacilitet2011Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Syftet med denna studie var att ta reda på om elitidrottare som spelar en bollsport har bättre djupseende, bättre förmåga att kunna ändra fokus mellan olika avstånd och mer uthålliga ögonmuskler än personer som inte spelar någon bollsport alls.

    Metod: Mätningarna utfördes på femton innebandyspelare som spelar på elitnivå och femton personer som inte spelar någon bollsport. Medelåldern var 22 år i båda grupperna. Först fick varje försöksperson svara på en enkät, sedan mättes visus upp monokulärt och binokulärt på 3 m med en logMAR visustavla. Efter det mättes djupseendet med Randot stereotest på 40 cm och sedan mättes försökspersonens förmåga att kunna ändra fokus mellan olika avstånd. Detta gjordes på 40 cm med en flipper med styrkorna ±2,00D. Sista mätningen var att få ett mått på hur uthålliga försökspersonens ögonmuskler var, detta gjordes på 40 cm med en flipper av styrkorna 3Δ Bas In/ 12Δ Bas Ut.

    Resultat: Medelvärdet på djupseendet i respektive grupp visade ingen statistisk signifikant skillnad mellan de båda grupperna (p=0,70). Det fanns en signifikant skillnad på medelvärdet mellan de båda grupperna när det gäller förmågan att kunna ändra fokus mellan olika avstånd (p=0,02). Medelvärdet på uthålligheten av ögonmusklerna visade ingen signifikant skillnad mellan de båda grupperna (p=0,08).

    Slutsats: Studien visade att innebandyspelare på elitnivå har bättre förmåga att ändra fokus mellan olika avstånd. Studien visade även att innebandypelare på elitnivå inte har mer uthålliga ögonmuskler eller bättre djupseende än de som inte spelar någon bollsport alls.

    Improving Electronic Health Records for Non-Swedish Speaking Refugees: A Qualitative Case Study2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Information and communication technology is used in healthcare in Sweden to improve health quality. Electronic Health Records are one of the technologies in healthcare which can increase a patient’s involvement in his/her healthcare and decision-making related to it. The patient can discuss the treatments, analyses and medical information stored in Electronic Health Records. The aim in this study is to investigate how the Electronics Health Records can be improved to motivate refugees in Sweden who cannot speak Swedish. This research is a qualitative interpretive case study. The methods used in this study are observation and interviews. Thematic analysis was used for data analysis. The findings show that refugees don’t receive information or instructions about how to use electronic health records properly. The language is the biggest hurdle to use electronic health records for refugee patients without knowing Swedish language. The findings further show that the electronic health records can be improved by adding sound or translated medical information in the diagnosis part of the electronic health record. This research might contribute to the healthcare process of any country in the world which has refugees and they use electronic health records.

    Syresättning av avloppsvatten: En undersökning av luftningsmetoder på reningsverk2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay has been done at the request of Marinfloc AB. It consists of various measurements and experiments investigating the sewage water treatment on a number of different plants. The measurements were executed in the part of the plants called secondary treatment. The objective with secondary treatment is to let micro-organisms remove dissolved and suspended biological and organic matter. The factors which were investigated were which methods are used to oxygenate the sewage water, what level of oxygen saturation is obtained with each method and the power consumption required oxygenating the sewage water. An experiment was carried out on Marinflocs’ own sewage treatment plant with the objective to determine if there is any time difference in oxygenating pure water versus unprocessed sewage water. The conclusion reached was that the four land-based sewage treatment plants that were investigated oxygenate by the same principle. The oxygenation is done by aeration from the bottom in respective aeration tank. The level of oxygen saturation was between 1, 8 – 5, 9 mg oxygen per liter sewage water in all plants. Marinflocs’ current sewage treatment plant uses another principle to oxygenate and its oxygen saturation was measured to a level of 12 mg/l. The experiment on Marinflocs’ own sewage treatment plant concluded that there is a time difference in oxygenating pure water versus unprocessed sewage water. The pure water gets oxygenated faster.

    Kan Entresto ersätta ACE-hämmare vid hjärtsvikt och är den behandlingen optimal med avseende på farmakogenetiken?2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Around 200,000–250,000 people suffer from heart failure in Sweden. Heart failure is a condition of impaired heart pumping capacity. The condition results in reduced quality of life, high morbidity and mortality and there have been many attempts to find suitable drug targets to minimize these consequences. Neurohormonal compensatory mechanisms, such as renin–angiotensin–aldosterone system, aim to restore blood pressure to normal levels again but in the long-term it also increases the stress on the heart. The hormone angiotensin II gets activated through this mechanism and is the reason behind the increased stress. Therefore, the hormone has been an important drug target for ACE inhibitors (ACEI) and AT1 blockers (ARB) to prevent antihypertensive effects. The enzyme neprilysin is another drug target whose inhibition is accomplished by using neprilysin inhibitors. Entresto® is a new medication that contains a neprilysin inhibitor and an ARB. The neprilysin inhibitory component, sacubitril, is activated by carboxylesterase 1 (CES1) but mutations in the gene encoding CES1 may cause a non-therapeutic effect. Additionally, patients with wild-type CES1 may risk unacceptable side effects such as rhabdomyolysis and Alzheimer's disease. The objective of this study is to investigate whether replacement of ACE inhibitors with Entresto is optimal in heart failure with regard to pharmacogenetics.

    This study is organized as a literature study in which five scientific articles (I-V) were analyzed and selected from PubMed database and through Linnaeus University's search engine, OneSearch. The studies show that Entresto is superior to enalapril in reducing the risk for cardiovascular death or hospitalization for heart failure. However, the effects of Entresto is dependent on a functioning CES1 gene because mutations like G143E cause a non-therapeutic effect. Enalapril has shown to be independent of such mutations.

    Theoretically, inhibition of neprilysin may cause accumulation of amyloid-β peptides (Aβ), which associates with Alzheimer's disease. Study IV, with the purpose to investigate the effect of Entresto on Aβ isoforms, showed no significant change in Aβ concentrations in cerebrospinal fluid. However, further studies with longer duration were suggested. On the other hand, study V shows that a combination of Entresto and statins increases the plasma concentration of statins. That in turn would increase the risk of a development of rhabdomyolysis. The conclusion is that it is not optimal to replace enalapril with Entresto in heart failure with regard to pharmacogenetics.

    ”Det beror ju på vad man vill lägga i ordet register” Petra Stenkula

    En fallstudie av polisens externa kriskommunikation i samband med romregistret

     

    Syfte             

    Syftet är att lämna ett bidrag till den svenska forskningen om kriskommunikation men även att bidra till den svenska samhällsdebatten om polisen som en central rättsmyndighet och deras hantering av romregisterkrisen.

     

    Metod          

    Via en kvalitativ metod analysers nyheter publicerade på polisens webbplats och polisens presskonferenser utifrån de valda teoretiska ramarna inom ämnet kriskommunikation.

     

    Resultat        

    Polisens kriskommunikation framstår som väldigt strategilös, under hela krisen ägnar sig polisen åt                               informationsinsamling för att förstår krisen och få en överblick över situationen men under tiden glömmer                     de den strategiska delen. Polisen är väldigt restriktiv i sin kriskommunikation, på webbplatsen är nyhetspubliceringarna rörande romregistret väldigt korta och konkreta, vissa är rena informationsanvisningar. Polisen förde även en inkonsekvent kriskommunikation, när Rikspolisstyrelsen pratade om analysfil som inte var i fas med lagstiftningen så pratade Skånepolisen om beslut ifrån år 2009 om tillstånd att upprätta den särskilda analysfilen. I sin kriskommunikation använder polisen många olika försvarsstrategier ifrån Corporate Apologia och Image Repair Theory. Strategierna som användes för att upprätthålla image var för många och olika för att uppfattas som trovärdiga medan polisen utförde i teorin en perfekt apologia. Polisen beklagade situationen, berättade om vilka åtgärder som skulle utföras och Justitiekanslern beslutade om kompensation till de drabbade.

    Abstract [en]

    The aim of this study was to examine the concept of “integration” within residential care homes for unaccompanied children. More specifically its aim was to find out how the social workers themselves within residential care homes for unaccompanied children understand the concept of integration and how they work for it. The study was based on a qualitative semi-structured interviews with seven social workers within four residential care homes for unaccompanied children. Six themes were identified that seemed to play a role in the discussions about integration: development-acceptance, learning process, communication & relationships, process, personality and common sense. The analysis was based on previous research in the field and the theory of action by Pierre Bourdieu called practical reason. As a conclusion the first three themes can be seen as an understanding of the concept of “integration”. The last three themes exemplify the practical integration work. Despite the lack of regulatory documents, the social workers show a common understanding of the concept and a similar implementation which can be explained by a dominant implicit doxa within the field.

    Direct three-dimensional head pose estimation from Kinect-type sensors2014In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 50, no 4, p. 268-270Article in journal (Refereed)
    Abstract [en]

    A direct method for recovering three-dimensional (3D) head motion parameters from a sequence of range images acquired by Kinect sensors is presented. Based on the range images, a new version of the optical flow constraint equation is derived, which can be used to directly estimate 3D motion parameters without any need of imposing other constraints. Since all calculations with the new constraint equation are based on the range images, Z(xyt), the existing techniques and experiences developed and accumulated on the topic of motion from optical flow can be directly applied simply by treating the range images as normal intensity images I(xyt). In this reported work, it is demonstrated how to employ the new optical flow constraint equation to recover the 3D motion of a moving head from the sequences of range images, and furthermore, how to use an old trick to handle the case when the optical flow is large. It is shown, in the end, that the performance of the proposed approach is comparable with that of some of the state-of-the-art approaches that use range data to recover 3D motion parameters.

    Ungdomar på SiS-institution: -Personalens uppfattning om och upplevelser av aggressivt beteende2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie var att få en inblick och förståelse för personalens uppfattningar om och upplevelser av ungdomars aggressiva beteenden som befinner sig på en SiS-institution. Dessutom har personalens bemötande gentemot dessa ungdomar belysts från svaren och resultaten av frågeställningarna. En kvalitativ forskningsmetod med utgångspunkt från hermeneutiken användes för att utföra studien tillsammans med semistrukturerade intervjuer med ett antal respondenter från en SiS-institution. von Wrights (2000) relationella och punktuella perspektiv användes som teoretisk utgångspunkt till studien. Resultatet redovisar att respondenterna uppfattade, upplevde och erfarar att ungdomarna som placeras vid institutionen minst någon gång under vistelsen uppvisar ett aggressivt beteende. Det kan även ses i resultatet att personalen upplever att dessa ungdomar i de flesta fall har många av de faktorer som orsakar ett aggressivt beteende med sig till institutionen från deras bakgrund och familjesituation.

    Abstract [en]

    This studie explores how a promotive youth movement that aims to activate adolescents in economically and socially exposed areas, can affect the youth’s participation in society and oppose their experience of stigmatization. The youth movement, whom is being studied, uses urban art expressions as a mean to engage and motivate the adolescents. The empirism has mostly been collected by a limited participatory observation, and through qualitative interviews with staff and adolescents in the movement. The result has been analyzed through Pierre Bourdieus field theory. To summarise, field theory consists in the hypothesis that the individual is socialized in to his or her way of thinking and being (habitus), based on in which circumstances the individual is raised (in which field). Habitus affects the choices the individual makes throughout life. An individuals habitus is affected by three types of capital, which Bourdieu has named economical-, social-, and cultural capital. This essay analyzes how the promotive youth movement contributes to the adolescent’s social- and cultural capital. I have found that this largely happens by giving the adolescents different types of tools to be seen and heard, based on the concept of hip hop as a political instrument. The most prominent tool in the everyday activities is the opportunity to record music in a professional studio. Other tools that are used are the opportunity to host the movements own radio show, participate in the arranging of different types of events, and such. I have also found that the support from an extra adult and the connection within the movement are central providers of social capital.

    Response strategies of traditional firms indisruptive times.: A case study on sustainable strategies of the hotel industry in response tothe sharing economy evolution.2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose - Traditional firms within mature markets are challenged, as they have to rely a lot on adaptation of new technologies in order to keep their service sales among consumers and survive in a highly competitive globalized environment. One of the examples of a mature industry is the hotel industry, in which sustainability is a vital necessity, however implementation efforts are slow. Nowadays, a business shift is occurring from traditional to disruptive innovation models. One such model is that of the sharing economy. The aim of this thesis therefore targets the finding of the understanding and reaction, by analyzing and describing actions, of traditional hotel firms for sustaining their business in times when sharing economy firms become increasingly influential on the traditional business.

    Design/methodology/approach - An abductive approach was followed throughout the thesis spanning a qualitative data analysis of the empirical base of the study, which consisted of six semi- structured interviews of traditional hotel firms that were chosen through theoretical sampling. The multiple and holistic case study setup is a means of explaining response strategies in the hotel industry.

    Findings - The findings are that while some are aware of the growing impact of sharing economy on the mature industry, few firms have concrete strategies to sustain their own business in the light of the upcoming challenges. Moreover, the interviewed firms have lost large percentages of their traditional direct sales channels, making it essential to sell increasingly through online channels and third party providers such as online travel agencies. This adds to the challenge that the service offerings of sharing economy firms and established firms are becoming more comparable to each other, making it easier for the customer to compare directly which choice is preferable. The empirical data suggests that this is of relevance for both the leisure and business segment of travelers. However, there were also positive effects found, that the sharing economy is an opportunity for traditional firms to learn and for travel destinations to be boosted through increased supply and variety.

    Research limitations/implications - The chosen case study setup is a means of explaining responses from the hotel industry due to the sharing economy. However, there is an indication that a similar phenomenon can occur in a different mature industry, such as the taxi industry with Uber or the financial industry with Bitcoin. Moreover, this case had hotel firms operating on a 3-star level or higher, which imposes potential limitations for the applicability. However, for the research implications this thesis includes a model that contains theoretical description of a practical phenomenon within a shifting context.

    Practical implications - Traditional businesses must find new ways to highlight their unique values, core competences and what most significantly distinguishes their offering, for example beyond being an accommodation provider, in order to develop a sustainable business that can withstand the challenges in the 21st century. It is recommended for firms to assess their position in the market, their customers and competitors to decide on which strategy is best suited, as it may vary with every firm. Analogous, it is not recommended to rest on previous successes.

    Originality/value - Increasing influence of the sharing economy forces traditional firms to respond with their own strategic countermeasures. However, the response of traditional firms to the impact of sharing economy firms is not well described and has empirically been insufficient. In this way, the thesis contributes to the existing research on the sharing economy and its impact by studying the consequences for and responses of firms in a mature industry. Therefore, it addressed challenges in theory all well as in practice for the affected businesses. The finding and combination of response strategies in this thesis presents a valuable contribution to academia and practical implications for the mature industries.

    A Luminous and Isolated Gamma-Ray Flare from the Blazar B2 1215+302017In: Astrophysical Journal, ISSN 0004-637X, E-ISSN 1538-4357, Vol. 836, no 2, article id 205Article in journal (Refereed)
    Abstract [en]

    B2 1215+30 is a BL-Lac-type blazar that was first detected at TeV energies by the MAGIC atmospheric Cherenkov telescopes and subsequently confirmed by the Very Energetic Radiation Imaging Telescope Array System (VERITAS) observatory with data collected between 2009 and 2012. In 2014 February 08, VERITAS detected a large-amplitude flare from B2. 1215+30 during routine monitoring observations of the blazar 1ES. 1218+304, located in the same field of view. The TeV flux reached 2.4 times the Crab Nebula flux with a variability timescale of <3.6 hr. Multiwavelength observations with Fermi-LAT, Swift, and the Tuorla Observatory revealed a correlated high GeV flux state and no significant optical counterpart to the flare, with a spectral energy distribution where the gamma-ray luminosity exceeds the synchrotron luminosity. When interpreted in the framework of a onezone leptonic model, the observed emission implies a high degree of beaming, with Doppler factor delta > 10, and an electron population with spectral index p < 2.3.

    Probiotika som behandling vid IBS2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: IBS (Irritable Bowel Syndrome) is a functional gastrointestinal disorder, with an unclear etiology and pathophysiology. IBS is a common disorder in the Western population and is characterized by recurrent abdominal pain/ discomfort, bloating, flatulence, diarrhea and/ or constipation. There is currently no cure for IBS, but the interest in probiotics as an option of treatment has recently increased. Probiotics have been defined as live microorganisms that, when administered in adequate amounts, provide a health benefit on the host, and are believed to have a symptomatic effect in IBS. Probiotics have therefore been of interest for the treatment in IBS.

    Purpose: The purpose of this study is to examine whether probiotics have a therapeutic effect and if it could be used as a treatment for IBS.

    Method: Five randomized, double-blind, placebo-controlled studies were reviewed that examined the therapeutic effect of different probiotics in the IBS-patients. Articles were obtained through searches in the medical database PubMed, during the month of February 2016.

    Results: Four of the five studies showed a significant improvement of symptoms especially in abdominal pain/ discomfort. The best results were seen in a study that investigated the probiotic Lactobacillus plantarum 299v. Three of the five studies showed a significant improvement in quality of life (QOL) of the subjects in the study. One of the five studies which examined the effect of Escherichia coli Nissle 1917, there was no significant difference between E.coli (probiotics) and placebo.

    Conclusion: There is reasonable evidence that treatment with certain probiotics might provide improvement in symptoms of abdominal pain/ discomfort, and increase patients quality of life based on the five studies. Further studies are required to determine the most effective probiotic, dose and duration of IBS-treatment.

    Maintenance Perception in Swedish SMEs (A local study in Kronoberg County)  2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Recognition of maintenance management as a significant factor holds the key to competitiveness in the global market irrespective of the size of the business. Maintenance management practices are primarily found in larger and multinational companies but the purpose of this paper is to investigate the maintenance practices that are used in SMEs of Sweden (Kronoberg County). The study is expected to expose the level of maintenance perception in the Swedish industry via a postal (and web based) questionnaire. The survey covered 74 company chosen from different sectors and produced a response rate of 20.3 percent. The main results achieved from the study show us difference between the maintenance perception and awareness of the maintenance. The respondents are aware of the importance of maintenance, but maintenance is still perceived as a necessary expense. Because according to the results of the survey the percentage of maintenance budget in comparison to the companies’ turnover is on average about 0.97% and it is very low. Again, when we look at the maintenance cost distribution of companies, spare parts and labour costs consist of 73 % of total maintenance cost, despite that they spend very little money for technology and training costs, their percentages in total cost are just 3% and 2%, also they still ignore statistical modelling (historical data) and condition monitoring. Moreover, just 27% of the participants use the maintenance key performance indicators (KPIs), and just 14% of them used basic KPIs which are used for measuring maintenance performance. There is a need to spend and invest more in maintenance especially they should invest more in technology and training to perform them. On the other hand, there is a need for choosing right maintenance strategy and service type, because these points are very important for an effective and economic maintenance management.

    Content creation activities related to content marketing through social media.: A qualitative study in a B2B context2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Companies have lately been engaging their business activities onto social mediaand its platforms. They are taking advantage of the opportunities provided by social media and they are starting to realize the importance of content marketing.

    Problem Discussion: Content marketing has been researched previously research. However, the research regarding B2B content marketing and the differences between B2B and B2C content is still rather limited. The question lingers whether the same principles apply to firms working with B2B as well. Moreover, a clear framework or guide regarding the way that content should be created does not yet exist – a guide including the aspects may be taken into account when creating content and implementing content marketing.

    Purpose: The purpose of this study is to understand and describe how companies deal with the content creation process, within content marketing through social media.

    Research Question: How do companies handle content creation for content marketing through social media?

    Methodology: This thesis has taken a qualitative and abductive approach on the study. It hasbeen based on a multiple-case study, where semi-structured interviews took place with sevenfirms working with content marketing and content creation - in a B2B context.

    Conclusion: All seven firms have a uniform understanding of content marketing, aligned withprevious research. The study concludes that there are similarities between the ways that companies handle content marketing. Furthermore, the study concludes that there are general traits that needs to always be taken into consideration when creating content s.a. long term planning, providing value to the customer, well thought out message and choosing the right channels for content distribution.

    A cost effective and environmentally friendly stormwater treatment method: The use of wood fly ash and H2O22011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This current study is a lab-scale investigation focused on the treatment of stormwater runoff generated in wood-storage areas. The main target constituents of the proposed treatment were: metals (Cu, Cd, Co, V, Pb, Zn, Ni, Cr, Fe, As), COD, TOC, Phenols, and color. The method implemented for this project follows the main concept of using low-cost and environmentally friendly technologies and had as main steps the use of a by-product of wood-based industries - wood fly ashes as sorbents - followed by oxidation with H2O2 (Hydrogen Peroxide). The results obtained during this investigation were vey promising since satisfactory removal % was achieved. Removal rates of 98.5%, 86%, 89.6%, 79.6% were achieved for color, chemical oxygen demand (COD), total organic carbon (TOC) and phenols respectively. Furthermore a decrease in metals concentrations was also observed with the exception of chromium. The study showed that for 300 ml storm water, optimum conditions were with 7g wood fly ash, 5 hours time reaction, pH≈11.46 and 150 μl of a 30% H2O2 solution in a room temperature. To conclude it can be stated that the use of a by-product from wood industry to treat contaminated water from the same sector, following the concept of a closed-loop system, is promising and possible. However further studies need to be conducted in order to evaluate such system in scaled-up conditions.

    Preparing HPC Applications for Exascale: Challenges and Recommendations2015In: Proceedings: 2015 18th International Conference on Network-Based Information Systems, NBiS 2015 / [ed] Barolli, L; Takizawa, M; Hsu, HH; Enokido, T; Xhafa, F, IEEE conference proceedings, 2015, p. 401-406Conference paper (Refereed)
    Abstract [en]

    While the HPC community is working towards the development of the first Exaflop computer (expected around 2020), after reaching the Petaflop milestone in 2008 still only few HPC applications are able to fully exploit the capabilities of Petaflop systems. In this paper we argue that efforts for preparing HPC applications for Exascale should start before such systems become available. We identify challenges that need to be addressed and recommend solutions in key areas of interest, including formal modeling, static analysis and optimization, runtime analysis and optimization, and autonomic computing. Furthermore, we outline a conceptual framework for porting HPC applications to future Exascale computing systems and propose steps for its implementation.

    The purpose with this lucubration is to investigate hairstylist student’s apprehension about the apprentice diploma. The apprentice diploma is an occupation verification indicating on the hairstylist’s knowledge and competence, and it is the only verification in the business that you can use in order to measure the students knowledge. Three students out of thirty, in year 2009, chose to graduate with an apprentice diploma. Based on these figures I am to investigate six graduating students opinion using qualitative interviews. Another quest is to inform and gain interest about the apprentice diploma.  The result demonstrate what earlier research already shows, amongst other things, that the students no longer have the practical knowledge needed in order to come to a worksite and therefore find it difficult to work as an apprentice. The business expects the students to be self-driven and dissatisfaction from the school and the business increases. Is the occupation as a hairstylist about to loose its profession or are you allowed to call yourself a professional without a proper diploma?

    Musikteorins applicering på ensembleämnet: - En studie i hur gymnasieelever anser att de använder sina musikteorikunskaper praktiskt.2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna uppsats var att undersöka i vilken utsträckning elever anser att de använde musikteoriämnet under ensemblelektioner på musiklinjen på gymnasiet, samt om och i så fall hur eleverna anser att teoretiska kunskaper påverkade deras ensemblespel. Det andra syftet var att ta reda på i vilken utsträckning elever anser att deras lärare i ensemble samtalade med dem om hur musikteorin kan användas på ensemblelektionerna. Genom enkätundersökning samlades data om detta in från elever på gymnasiet. Dessa data granskades sedan med hjälp av den sociokulturella teorin. Respondenterna svarade väldigt olika på hur vanligt det är att de själva använder musikteorin under ensemblelektionerna. Många svarade att de händer ganska ofta medan ungefär lika många svarade att det händer ganska sällan. Elevernas svar visar att när musikteorin används så sker det icke-verbalt. I en närmare granskning visade det sig att majoriteten av eleverna ansåg att de olika moment ur musikteorin enkäten frågade om används inget eller sällan under ensemblelektionen. En stor majoritet av eleverna sa själva att det dem lärde sig på musikteorilektionerna utvecklade dem som musiker och att många delar ur musikteorins kursplan var viktiga för deras spel i ensemblen.

    Nutidens musikteori: -En undersökning av musikteorilärares metoder.2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete syftar till att undersöka hur musikteorilärare på gymnasiet arbetar med ämnet musikteori genom observationer av lektioner och intervjuer med lärare. Fokus ligger på att granska utrymmet som ges till elevsamarbete, användandet av digitala verktyg samt hur lärarna relaterar ämnet till elevernas praktiska användande. Detta har undersökts genom att först observera musikteorilärare under lektionstillfällen för att hitta intressanta aspekter av deras undervisning, inspirerat av metoden grounded theory. Sedan intervjuades dessa musikteorilärare närmre om just de aspekter som ansågs intressanta. I arbetets analysdel relateras sedan lärarnas svar till en teori om lärande som kallas Collaborative learning. Inom denna teori är grupparbete, ofta assisterat med digitala verktyg mycket viktigt, vilket är relevant för detta arbete. Under intervjuerna berättade en av de två intervjuade lärarna att grupparbeten var väldigt vanliga och att digitala verktyg användes ofta i undervisningen. Den andre läraren berättade motsatsen: grupparbeten skedde sällan och digitala verktyg hade provats under lektionstillfällen, men med otillfredsställande resultat. Båda lärarna relaterade musikteoriämnet till elevernas praktiska användande.

    Sustainopreneurship - Business with a Cause: Conceptualizing Entrepreneurship for Sustainability2007Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis presents a tentative definition of the concept of sustainopreneurship - in the most simplified form described as entrepreneurship and innovation for sustainability - “Business with a Cause”. The concept takes its departure from generic entrepreneurship theory development, its extensions and further contextualization into the domains of sustainability, primarily through recent research. A literature review provides core references related to the conceptualization of sustainability entrepreneurship. A claim is made that there is a need for further conceptual development, especially viewed in contrast to the empirical material and experience, when digesting the literature that deals with concepts preceding sustainopreneurship. These concepts are eco-preneurship and social entrepreneurship, as well as current descriptions of sustainability entrepreneurship, including some sources where the word sustainopreneurship in itself is introduced for the first time. The methodological approach used when conducting the literature review is an analytical stance. Additional analysis, integrating and extending the reviewed sources, leads us to a performative definition of sustainopreneurship. This tentative definition is presented as an imagined prospective wordbook entry in a “future history” format. One of the key distinctions in between entrepreneurship in general and sustainopreneurship, is that sustainopreneurship is mission- and cause oriented - business activity is used as a means to solve sustainability-related problems. In short, to turn business activity from being a part of the problem to be a part of the solution.

    This world of ideas is set in contrast to the practical enaction of On a Mission Sweden – Inc. Ass, and the seven brands developed from this business platform – Club PuLS™, DJ Anders, SEEDS Sustainability Investment Fund, SEEDS Magazine, Ignition®, SLICE Services and Publishing™ and S*E*N*S*A. Three of these only reached conceptual stage for future potential launch. Four got established, and of these; one idle, two spun off in their own ventures, and one intended to spin off during 2007. Entrepreneurship as a concept to describe the nature of these ventures was experienced as insufficient, until 2003, when the concept of “sustainopreneurship” was found by serendipity. The conceptual dissatisfaction with “entrepreneurship-as-usual”, together with finding this new concept, made me instantly embrace this concept in the moment when stumbled upon. Another major driver for this work is a strong aspiration to take the abstract, general words and statements from world summits and conferences to the practical, hands on, down to earth, grass-root, local level with real world interaction to make possibilities of the problems related to the sustainability agenda. The ventures created from a time span of over seven years, forms a vast, deep, dense, intense and extremely rich “gross” empirical base from where the study collects its selective “net” material relevant for this study. The methodological approach to make sense and use of these serial and parallel self-initiated and self-experienced venturing processes is enactive research. The enactive research provides an opportunity to test the suggested formulation of sustainopreneurship – from the abstract idea to the concrete interaction. A special form of ethnography is used named self-ethnography. The ventures who have proven to perpetually evolve, develop and sustain are focused; On a Mission Sweden – Inc. Ass. and Ignition®. These ventures have provided the most significant change in both idea development, practice, and effect - both regards my inner world of insight breakthroughs and personal development, and the findings on a more abstract, conceptual, theoretical level. In order to highlight the three key dimensions of the concept, some key courses of events have been selected where they are considered to hold illustrative power: Firstly, the central events before the formalized venturing. Secondly, the milestones singled out during the venturing. Thirdly, some post-venture reflections around the process as such. The ethnographic style of the tales of the field is predominantly realist, with some degree impressionist.

    The final chapter summarizes and presents an intermediary conclusion whether the concept has met the test and also discusses the meaning of the exercise as a whole. My own function is examined and evaluated briefly. The promise of the conceptual introduction is contrasted towards the approaches-as-usual regards the sustainability agenda that introduced the thesis, and some key points are delivered. Venturing in the name of sustainability allows agents to “act outside the box” related to the institutional framework that governs the structures that is set to solve the problems today, equipped with an upgraded mindset, operating with an agility made possible by the flexibility offered by creative business organizing. The quest to make (business) opportunities from the agenda set by sustainability, and organizing upon them in itself creates a sustaining meaning internally within the team to be able to ride through the storms – the same force traditionally driving NGO’s “not-for profit”, now coupled with a good business sense operating “for-profit”, with profit as a means, not as an end in itself - in a new in-between-land named “for prosperity”. When properly understood from knowledge increasing among other stakeholders than the sustainopreneurial teams and their closest supporters and early adopters, the welcoming of sustainopreneurial ventures are destined to increase. Proliferation and diffusion of sustainopreneurship in idea, applied interaction and reflective practice beyond this point can turn sustainability to be the main driver for business activity, internalizing the external sustainability demands as the primary purpose of the business creation and idea, forming its strategic intent, and integrated in its “organizational DNA”. Sustainopreneurship holds the power to give even more leverage to forces emerging from the business world that contributes to sustainability. Throughout the process, a question has been emerging to serve as a new opening for further interaction, where the claim is that sustainopreneurship delivers a good part of the answer;

    How can we innovate and interact in order to reach a critical mass of people and energies to create a sustainable world?

    Hur värderas en trend?: Lagerredovisning i konfektionsbranschen2018Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Title: How is a trend valued? Inventory accounting in the clothing industry.

    Background: Inventory is one of the major asset items in the balance sheet for clothing companies. It is therefore important that the valuation of it becomes fair and provides accurate information to the company's stakeholders. As trends today are moving faster, companies' inventories are subjected to greater obsolescence than before, making it harder to value. This means that companies in their pursuit of legitimate inventory accounting need to relate to their social context. This will be the basis for the study's problem and purpose, which therefore aims to identify the social factors that underlie inventory reporting in clothing companies.

    Purpose: The study intends to provide an understanding of how the social context shapes the accounting of inventories in the clothing industry. The purpose is to supplement the knowledge of how clothing companies responds to the challenges and uncertainties in inventory accounting.

    Method: Based on existing literature, a social context has been drawn up, to which companies need to relate its inventory report. The thesis then consists of a qualitative interview study with companies in the clothing industry. The purpose of the interviews is also to identify additional factors that may affect how companies inventory accounting shapes.

    Results / Conclusions: The results of the survey shows that companies today are aware of the problems with fast-paced trends, but that's nothing they take into major account in their inventory accounting. It also appears that the inventory valuation in the industry today is standardized.
