    Att arbeta integrerat med asylbarn i allmän förskola: En kvalitativ studie baserad på lärarintervjuer2013Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med föreliggande studie var att vinna kunskap om och ge en bild av hur sex pedagoger inom förskolan upplever att det är att arbeta integrerat med asylbarn i den allmänna förskolan och att ge en bild av vad pedagogerna berättar om hur detta arbete organiseras.  För att få svar på studiens frågor har en kvalitativ forskningsintervju använts. Två forskningsfrågor skapades från vilka intervjufrågorna huvudsakligen formades. Forskningsfrågorna var: Vilka förutsättningar för arbetet med asylbarn ger pedagogerna uttryck för och på vilket sätt organiseras den allmänna förskolan för asylbarn. Som analysredskap i studien har den sociokulturella och den interkulturella teorin använts. Studiens resultat visar att integreringen av asylbarn i den allmänna förskolan innebär att pedagogerna har att förhålla sig till att arbeta med asylbarn och deras föräldrar utan att dela språk eller känna till mycket om deras bakgrund. De måste också arbeta i en barngrupp som kan vara extra rörlig och instabil till storlek och dagsform. Resultatet visar också att den goda intention som det är att asylbarnen ska få komma varje dag till den allmänna förskolan gör att tiden på förskolan blir för kort för att pedagogerna ska kunna arbeta mer planerat med asylbarnens språk och egna kultur.

    Incubator performance: An efficiency frontier analysis2008In: International Journal of Business Innovation and Research, ISSN 1751-0252, Vol. 2, no 4, 354-380 p.Article in journal (Refereed)
    Abstract [en]

    Assessments and evaluations of incubators has been a topic of discussion for as long as incubators have been in existence due to the fact that there has not been an agreement on how to determine good performance. This paper demonstrates the use of Data Envelopment Analysis (DEA) when studying performance of incubators. More specifically, it does so within the four dimensions of cooperation with universities, business networks, external funding and competence development on a sample of 16 Swedish incubators. We show that DEA enables us to measure non-numerical dimensions, and to simultaneously take into account the efforts made by both the incubator and the outcomes. Moreover, DEA provides benchmarks and, based on a model that divides the incubators into four different groups, illustrates the difference between the benchmark and the incubators' current situation.

    Critical dimensions for technology transfer Incubator-facilitated links between finance, academia and NTBFs2008In: International Journal of Management and Enterprise Development, ISSN 1468-4330, Vol. 5, no 3, 331-335 p.Article in journal (Refereed)
    Abstract [en]

    This paper explores incubator facilitation of technology transfer for their New Technology-Based Firms (NTBFs). Empirical evidence gathered from six interviews with incubator managers, together with a survey of 131 NTBFs in incubators in Sweden, in 2005, and the findings made in a survey of 273 NTBFs situated inside-and-outside Science Parks in 1999, are used for the exploration. It is suggested that incubators do facilitate technology transfer for their NTBFs. It is further suggested that the development towards increased ability to facilitate technology transfer will continue as a results of the efforts made on the incubator and systemic level.

    Corporate governance and performance of small high-tech firms in Sweden2006In: Technovation, ISSN 0166-4972, Vol. 26, no 8, 955-968 p.Article in journal (Refereed)
    Abstract [en]

    The approach uses data from a sample of 183 small high-tech firms, new technology-based firms (small high-tech firms) in Sweden (54 variables under the headings of work experience, board and advice, financing, motivation—performance priorities, technological innovation and strategy). This study identifies some core areas of importance in corporate governance. Few managers in this study had a strong background and experience of finance and the preparation of business. Only 64 per cent of the managers have had previous work experience before starting the firm. The survey makes it clear that the small high-tech firms are likely to have a strong link with banking institutions. The consequence of these links is that most of the firm's capital supply is from banks, and that there are strong ownership links between banks and industry. The background of the founder does seem to have had an effect on the problem of financing and ownership issues. It is private sector organizations (banks) and families that are most frequently consulted by small high-tech firms (However, low means). It is also the private and public sector organizations, in connection with external board membership, regional development agencies and banks that are most frequently consulted. In the future, it is reasonable to search for factor patterns that can begin to explain and predict the direction of corporate governance in small new technology-based firms.

    Ett deltagande, för vem?: En kvalitativ intervjustudie om gymnasieelevers deltagande i Idrott och hälsa 12016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study was to investigate, at first, why students in upper secondary school in Sweden participate or not in Physical education and health (PEH) and also find out what changes the subject need that can affect their participation. To get answers out of the in-vestigation, we formulated questions about what preconceptions the students of an specific group have about participation and non-participation in PEH and what changes the subject need, according to the students, to become a subject for all students. The study was based on a qualitative method, by using interviews of ten students from Swedish upper secondary school. The students were from two schools in a mediumsized region and from different programmes.

    The results of the study shows clearly that the content and the grades in PEH affects the student’s participation, which was crucial to whether they felt they wanted to participate actively in the lessons or not. The grades were considered as important and affected the participation even though some of the students were not interested in the content, but they still did the things that the teacher demanded. Despite this, the attitudes towards the subject were positive among the interviewed students. The factors the students think can change the participation to more actively is implement more activities as dance, individual training but also, delimit ballsports. It seems like the interviewed students are searching for meaningfulness in the lessons of the subject with a link between the curriculum and grading criteria.

    Vill kunder handla receptfria läkemedel i dagligvaruhandeln?: - En enkätundersökning2008Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpStudent thesis
    Abstract [sv]

    Sammanfattning

    I Sverige har det statliga apoteketsmonopolet ifrågasatts en längre tid och regeringen utreder nu möjligheten att konkurrensutsätta läkemedelsförsäljningen. Det har även föreslagits i den statliga utredningen (SOU 2008:4 del 2) att ett begränsat sortiment av OTC läkemedel (over the counter = receptfria läkemedel) ska få säljas i dagligvaruhandeln utan farmaceutiskt kompetenskrav. Vid korrekt användning och tillgång till rätt rådgivning kan OTC läkemedel vara till en stor hjälp för den enskilde individen vid egenvård och därigenom också bidra till avlastning på sjukvårdens resursers. Vid felanvändning av OTC läkemedel (över/underdosering, fel indikationsområde etc.), kan de istället få motsatt effekt. Syftet med denna enkätstudie var därför att utforska om konsumenter av OTC läkemedel i Sverige önskar få tillgång till dessa läkemedel i t ex livsmedelsbutiker, där de inte har tillgång till personlig farmaceutisk rådgivning, vidare var avsikten att undersöka hur de i dagligvaruhandeln önskade få läkemedelsinformation. I februari 2008 gjordes en enkätstudie i Västervik som inkluderade 48 deltagare varav 29 kvinnor och 19 män. Studien visade att 71 % av deltagarna hade en positiv inställning till att köpa OTC läkemedel i livsmedelsbutiker, 58 % skulle skaffa information genom läkemedelsförpackning och bipacksedel i kombination med att de tidigare använt läkemedlet. Önskan om tillgång till personlig rådgivning på inköpsstället var störst i åldern ≤ 35 år, där 38 % ansåg sig vilja det. Slutsats av studien är att majoriteten vill kunna handla OTC läkemedel i dagligvaruhandeln och information skulle de få främst från läkemedelsförpackning/bipacksedel i kombination med erfarenheter från tidigare användning.

    Att vara syskon eller partner till en person med ätstörningsproblematik2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna uppsats har varit att belysa behandlares uppfattningar om syskon och partners upplevelser av att ha en nära person med en ätstörning, samt betydelsen av att involvera dem i den drabbades behandling. Studien genomfördes med en kvalitativ metod där semistrukturerade intervjuer utfördes med 6 behandlare på olika ätstörningsverksamheter i Sverige. Resultat och slutsats visade att syskon och partners, samt andra närstående, är betydelsefulla för patientens tillfriskande. Det är viktigt att syskon och partners involveras i behandling, och att de får information om sjukdom och behandling. Syskon ska inte anta en ansvarsroll, medan partner behöver ta ett visst ansvar i vardagen. Ätstörningar har en tydlig påverkan på partners och syskon, samt på närstående i allmänhet. Närstående bör få goda verktyg till hur de kan vara ett stöd på bästa sätt till den drabbade. Behandlaren ska bemöta närstående med förståelse, respekt och ingen skuldbeläggning. Det är väsentligt för patientens motivation och tillfrisknande att det finns en god och nära relation till de närstående som är involverade i behandlingen. Det finns en brist på forskning inom detta område. Vidare forskning krävs för att stärka studiens resultat och slutsats.

    Varför lyckas inte alla?: En studie på Hantverksprogrammet Frisör och Florist om skillnader mellan hög- och lågpresterande elever.2011Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Our purpose with this study was to investigate whether there was any difference between high and low performing students from selected aspects such as choice of studies, achievement, self-image, motivation, confidence and career choices.

    A training professional in today's schools requires knowledge of how young people think about their lives for us to help students develop both high-and low-performing students. Students have different conditions, but no matter good or bad conditions, each individual pupil must be allowed to develop.

    The concepts used in the study are of study, self-image, motivation, achievement in the future and career choices. In the background, describes these concepts through literature study. The method we have used was semi-structured interviews. Which means a fixed structure, but with room for follow-up questions.

    The results of our study indicate that there were clear differences between high-and low-performing students. The differences suggest that the high-performing students were more conscious about their study options than low-performing students. Differences were also in the students' views of themselves,where the high-performance had a lower self- image than the low-performing students had. High performance compared each other more often with other people and was more unsure of themselves, however, the motivation was significantly higher among the high-performance students, performance showed the same results. The high-performing students had a clearer vision of the future and that they had a clearer picture of their career choice than the low-performing students.

    Discussion on how we as educators can strengthen each student based on their individual needs have been based on results of the study.

    Kalmar - ett platsvarumärke i skuggan av Öland och Glasriket: En studie om destinationsutveckling2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Turismen i Kalmar har ökat de senaste åren, men hamnar till synes i skymundan av Öland och Glasriket. Hur får man besökare att få upp ögonen för Kalmar som primära resmålet och hur får man dem att stanna? Vi har i denna uppsats intresserat oss för att ta reda på hur ett starkt platsvarumärke skapas och vad som således krävs för att bli en framgångsrik destination, samt hur man kan använda sig av platsmarknadsföring för att nå ut med platsvarumärket till potentiella målgrupper.

    Vilka problem finns det med förfalskade läkemedel?2014Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Världsmarknaden för läkemedlen beräknades år 2011 till 900 miljarder US$ enligt IMS-health. Marknaden för illegala läkemedel uppskattas vara värd mellan 75-200 miljarder dollar. I Sverige uppskattas den illegala läkemedelsmarknaden till motsvarande ≤0,5 %. Straffet för insmuggling av läkemedel till Sverige är böter eller max 2 års fängelse. Tullverket räknar med att man endast hittar 10 % av det som smugglas in. I andra länder kan straffet variera mellan böter (ekonomisk brottslighet i Afrika) till dödsstraff i Kina.

    I Utvecklingsländerna uppskattas 10-30 % av alla läkemedel som säljs vara förfalskade, jmf 1 % I-länderna. l. Förekomsten av förfalskade läkemedel har många allvarliga konsekvenser på människor som exempelvis, utebliven effekt, toxiska reaktioner, förgiftningar, som kan i värsta fall leda till döden. Ett annat alvarligt problem är resistensutveckling, ökad spridning av smittsamammasjukdomar som exempel, tuberkulos och/ eller HIV/AIDS.

    Syftet med detta examensarbete är att besvara frågan: Vilka problem ger den ökande förekomsten av förfalskade läkemedel i samhället. Undersökningen fokuserar på livstidsläkemedel, dvs ett läkemedel en person måste ta resten av sitt liv för behandling av sin kroniska sjukdom.

    För att komma till rätta med de problem, som förfalskade läkemedel, skapar krävs ett mer utvecklat samarbete mellan olika läkemedelsmyndigheter, läkemedelsföretag, internationella polisorganisationer, tull m.fl. Arbetet med att utveckla förpackningar som är svåra att förfalska bör intensifieras. Straffsatser bör kanske ses över. Det är viktigt att öka medvetandet bland allmänheten om risker med att köpa läkemedel utanför apotek (t ex via nätet).

    The use of the prepositions to and with after the verb to talk in British and American English: A corpus-based study2007Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This paper is a study of the use of the prepositions to/with after the verb to talk in British and American English. The research is based on the material from the COBUILDDirect corpus, Longman American Spoken Corpus and New York Times CD-ROM. The common and different features of the use of talk to/with in different genres of American and British English as well as in written and spoken English were studied; special attention was paid to the factors which influence the choice of the prepositions. The research has shown that generally talk with is used much less than talk to and probably is undergoing the process of narrowing of meaning. With after talk seems to be used most often to refer to two-way communication while talk to is used to refer to both one- and two-way communication and is, therefore, more universal than talk with.

    Olika publiker, olika livsstilar: Om idrott, kultur och regional utveckling2008Book (Other academic)
    Abstract [sv]

    I föreliggande rapport studeras vilka sociala värden som elitidrotten och kulturen genererar för invånarna i landsortspräglade län som Blekinge, Halland, Kalmar och Kronoberg. Studien syftar till att lämna ett bidrag till den samhällsvetenskapliga idrottsforskningen, och ge ökad kunskap om idrottens och kulturens betydelse för den regionala utvecklingen.

    Studiens material vilar på en postenkät skickad till 1500 slumpmässigt utvalda personer i respektive län. Det sammanlagda antalet besvarade enkäter uppgick till 3181 stycken, vilket ger en nettosvarsfrekvens på 54 procent.

    Rapporten visar bland annat att både idrott och kultur värderas relativt högt och konsumeras i relativt stor utsträckning. Beträffande idrott konsumeras främst breddidrottsliga evenemang, och vad gäller kultur besöks bibliotek och biografer oftare än exempelvis teatrar.

    Studien visar också att de kultur- respektive idrottsintresserade skiljer sig åt vad gäller demografi, men även vad gäller livsstil. De idrottsintresserade har en mer folklig och lantlig prägel, medan de kulturintresserade är att betrakta som en välutbildad kosmopolitisk grupp. Med tanke på de sistnämndas ökade rörlighet är satsningar på kultur ej att förringa. Denna typ av satsningar kan få denna resursstarka grupp att dels stanna kvar i landsorten, dels flytta in till densamma.

    Digitalisering och social exklusion: Om medborgares användning av och attityder till Arbetsförmedlingens digitala tjänster2008Book (Other academic)
    Abstract [en]

    This research report focuses on the users of e-government in a social science perspective. Our aim is to study how different social groups, registered at the Swedish Public Employment Service, relate to the internet, the agency and the services offered on its website (www.ams.se).

    The field of e-government research is dominated by studies that centre attention on the supply side (videlicet research investigating the entrance of IT in organizations and the implications that new technology have to these), while usercentred research (demand side) is still scarce. Our study, focusing on how citizens relate to the internet in general and e-government in particular, therefore helps to bridge a knowledge gap within the field.

    Our survey is based on a questionnaire sent to 2 000 randomly selected persons, all registered at the Swedish Public Employment Service. Of these, 762 job seekers responded, which gives us a frequency rate of 40 percent. The questions asked were related to the job seekers’ usage of and attitudes towards the internet in general and the agency’s webpage in particular, but also to their attitudes to the Swedish Public Employment Service.

    The main results show that social factors, particularly education, play a major role for the job seekers’ ability to use the web based services offered by the agency. People with a lower educational level are less inclined to use the agency’s website, and at the same time they experience the site as more complicated to use. We also found a strong link between the relations to the internet (access, usage, experience and attitudes) and the relations to the agency’s website. Those with advantaged internet relations – mostly well educated people, white collars and people living in bigger cities – also use the agency’s website more diligently and tend to have more positive attitudes towards it (and vice versa). Thus, its necessary to talk in terms of digitally well equipped and less well equipped groups.

    The unequal relations to the internet in general and the agency’s website in particular not only indicate that e-government is more suitable for the digitally well equipped, but that it in fact exclude those with less digital resources. This new kind of exclusion has great implications for the job seekers’ possibilities to enter the labour market, and to act their role as citizens. If e government also means a reformation of the citizen role – in the sense of increased individual responsibility towards the government - not bridging the digital divide will carry even more exclusion to those that’s already excluded.

    Properites of "Good" Java Examples2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Example programs are well known as an important tool to learn computer programming. Realizing the signicance of example programs, this study has been conducted with a goalto measure and evaluate the quality of examples used in academia. We make a distinctionbetween good and bad examples, as badly designed examples may prove harmful for novice learners. In general, students differ from expert programmers in their approach to read and comprehend a program. How do students understand example programs is explored in the light of classical theories and models of program comprehension. Key factors that impact program quality and comprehension are identified. To evaluate as well as improve the quality of examples, a set of quality attributes is proposed. Relationship between program complexity and quality is examined. We rate readability as a prime quality attribute and hypothesize that example programs with low readability are difficult to understand. Software Reading Ease Score (SRES), a program readability metric proposed by Börstler et al. is implemented to provide a readability measurement tool. SRES is based on lexical tokens and is easy to compute using static code analysis techniques. To validate SRES metric, results are statistically analyzed in correlation to earlier existing well acknowledged software metrics.

    Towards autonomic software product lines2011In: SPLC '11 Proceedings of the 15th International Software Product Line Conference, Volume 2, ACM Press, 2011, 44:1-44:8 p.Conference paper (Refereed)
    Abstract [en]

    We envision an Autonomic Software Product Line (ASPL). The ASPL is a dynamic software product line that supports self adaptable products. We plan to use reflective architecture to model and develop ASPL. To evaluate the approach, we have implemented three autonomic product lines which show promising results. The ASPL approach is at initial stages, and require additional work. We plan to exploit online learning to realize more dynamic software product lines to cope with the problem of product line evolution. We propose on-line knowledge sharing among products in a product line to achieve continuous improvement of quality in product line products.

    Architectural reasoning for dynamic software product lines2013In: Proceedings of the 17th International Software Product Line Conference co-located workshops, ACM Press, 2013, 117-124 p.Conference paper (Refereed)
    Abstract [en]

    Software quality is critical in today's software systems. A challenge is the trade-off situation architects face in the design process. Designers often have two or more alternatives, which must be compared and put into context before a decision is made. The challenge becomes even more complex for dynamic software product lines, where domain designers have to take runtime variations into consideration as well. To address the problem we propose extensions to an architectural reasoning framework with constructs/artifacts to define and model a domain's scope and dynamic variability. The extended reasoning framework encapsulates knowledge to understand and reason about domain quality behavior and self-adaptation as a primary variability mechanism. The framework is demonstrated for a self-configuration property, self-upgradability on an educational product-line.

    Harnessing Variability in Product-lines of Self-adaptive Software Systems2015In: Proceedings of the 19th International Conference on Software Product Line: SPLC '15, ACM Press, 2015, 191-200 p.Conference paper (Refereed)
    Abstract [en]

    This work studies systematic reuse in the context of self-adaptive software systems. In our work, we realized that managing variability for such platforms is different compared to traditional platforms, primarily due to the run-time variability and system uncertainties. Motivated by the fact that recent trends show that self-adaptation will be used more often in future system generation and that software reuse state-of-practice or research do not provide sufficient support, we have investigated the problems and possibly resolutions in this context. We have analyzed variability for these systems, using a systematic reuse prism, and identified a research gap in variability management. The analysis divides variability handling into four activities: (1) identify variability, (2) constrain variability, (3) implement variability, and (4) manage variability. Based on the findings we envision a reuse framework for the specific domain and present an example framework that addresses some of the identified challenges. We argue that it provides basic support for engineering self-adaptive software systems with systematic reuse. We discuss some important avenues of research for achieving the vision.

    Software architecture serves as a foundation for the design and development of software systems. Designing an architecture requires extensive analysis and reasoning. The study presented herein focuses on the architectural analysis and reasoning in support of engineering self-adaptive software systems with systematic reuse. Designing self-adaptive software systems with systematic reuse introduces variability along three dimensions; adding more complexity to the architectural analysis and reasoning process. To this end, the study presents an extended Architectural Reasoning Framework with dedicated reasoning support for self-adaptive systems and reuse. To evaluate the proposed framework, we conducted an initial feasibility case study, which concludes that the proposed framework assists the domain architects to increase reusability, reduce fault density, and eliminate differences in skills and experiences among architects, which were our research goals and are decisive factors for a system's overall quality.

    Rigorous architectural reasoning for self-adaptive software systems2016In: Proceedings: First Workshop on Qualitative Reasoning abut Software Architectures, QRASA 2016 / [ed] Lisa O'Conner, IEEE, 2016, 11-18 p.Conference paper (Refereed)
    Abstract [en]

    Designing a software architecture requires architectural reasoning, i.e., activities that translate requirements to an architecture solution. Architectural reasoning is particularly challenging in the design of product-lines of self-adaptive systems, which involve variability both at development time and runtime. In previous work we developed an extended Architectural Reasoning Framework (eARF) to address this challenge. However, evaluation of the eARF showed that the framework lacked support for rigorous reasoning, ensuring that the design complies to the requirements. In this paper, we introduce an analytical framework that enhances eARF with such support. The framework defines a set of artifacts and a series of activities. Artifacts include templates to specify domain quality attribute scenarios, concrete models, and properties. The activities support architects with transforming requirement scenarios to architecture models that comply to required properties. Our focus in this paper is on architectural reasoning support for a single product instance. We illustrate the benefits of the approach by applying it to an example client-server system, and outline challenges for future work. © 2016 IEEE.

    Autonomic Software Product Lines (ASPL)2010In: ECSA '10 Proceedings of the Fourth European Conference on Software Architecture: Companion Volume / [ed] Carlos E. Cuesta, ACM Press, 2010, 324-331 p.Conference paper (Refereed)
    Abstract [en]

    We describe ongoing work on a variability mechanism for Autonomic Software Product Lines (ASPL). The autonomic software product lines have self-management characteristics that make product line instances more resilient to context changes and some aspects of product line evolution. Instances sense the context, selects and bind the best component variants to variation-points at run-time. The variability mechanism we describe is composed of a profile guided dispatch based on off-line and on-line training processes. Together they form a simple, yet powerful variability mechanism that continuously learns, which variants to bind given the current context and system goals.

    Modeling Variability in Product Lines Using Domain Quality Attribute Scenarios2012In: Proceedings of the WICSA/ECSA 2012 Companion Volume, ACM Press, 2012, 135-142 p.Conference paper (Refereed)
    Abstract [en]

    The concept of variability is fundamental in software product lines and a successful implementation of a product line largely depends on how well domain requirements and their variability are specified, managed, and realized. While developing an educational software product line, we identified a lack of support to specify variability in quality concerns. To address this problem we propose an approach to model variability in quality concerns, which is an extension of quality attribute scenarios. In particular, we propose domain quality attribute scenarios, which extend standard quality attribute scenarios with additional information to support specification of variability and deriving product specific scenarios. We demonstrate the approach with scenarios for robustness and upgradability requirements in the educational software product line.

    Knowledge evolution in autonomic software product lines2011In: SPLC '11 Proceedings of the 15th International Software Product Line Conference, Volume 2, New York, NY, USA: ACM Press, 2011, 36:1-36:8 p.Conference paper (Refereed)
    Abstract [en]

    We describe ongoing work in knowledge evolution management for autonomic software product lines. We explore how an autonomic product line may benefit from new knowledge originating from different source activities and artifacts at run time. The motivation for sharing run-time knowledge is that products may self-optimize at run time and thus improve quality faster compared to traditional software product line evolution. We propose two mechanisms that support knowledge evolution in product lines: online learning and knowledge sharing. We describe two basic scenarios for runtime knowledge evolution that involves these mechanisms. We evaluate online learning and knowledge sharing in a small product line setting that shows promising results.

    Limits on a muon flux from Kaluza-Klein dark matter annihilations in the Sun from the IceCube 22-string detector2010In: Physical Review D, ISSN 1550-7998, E-ISSN 1550-2368, Vol. 81, no 5, Article ID: 057101- p.Article in journal (Refereed)
    Abstract [en]

    A search for muon neutrinos from Kaluza-Klein dark matter annihilations in the Sun has been performed with the 22-string configuration of the IceCube neutrino detector using data collected in 104.3 days of live time in 2007. No excess over the expected atmospheric background has been observed. Upper limits have been obtained on the annihilation rate of captured lightest Kaluza-Klein particle (LKP) WIMPs in the Sun and converted to limits on the LKP-proton cross sections for LKP masses in the range 250-3000 GeV. These results are the most stringent limits to date on LKP annihilation in the Sun.

    SEARCH FOR MUON NEUTRINOS FROM GAMMA-RAY BURSTS WITH THE IceCube NEUTRINO TELESCOPE2010In: Astrophysical Journal, ISSN 0004-637X, E-ISSN 1538-4357, Vol. 710, no 1, 346-359 p.Article in journal (Refereed)
    Abstract [en]

    We present the results of searches for high-energy muon neutrinos from 41 gamma-ray bursts (GRBs) in the northern sky with the IceCube detector in its 22 string configuration active in 2007/2008. The searches cover both the prompt and a possible precursor emission as well as a model-independent, wide time window of -1 hr to + 3 hr around each GRB. In contrast to previous searches with a large GRB population, we do not utilize a standard Waxman-Bahcall GRB flux for the prompt emission but calculate individual neutrino spectra for all 41 GRBs from the burst parameters measured by satellites. For all of the three time windows, the best estimate for the number of signal events is zero. Therefore, we place 90% CL upper limits on the fluence from the prompt phase of 3.7 x 10(-3) erg cm(-2) (72 TeV-6.5 PeV) and on the fluence from the precursor phase of 2.3 x 10(-3) erg cm(-2) (2.2-55 TeV), where the quoted energy ranges contain 90% of the expected signal events in the detector. The 90% CL upper limit for the wide time window is 2.7 x 10(-3) erg cm(-2) (3 TeV-2.8 PeV) assuming an E-2 flux.

    SEARCH FOR HIGH-ENERGY MUON NEUTRINOS FROM THE "NAKED-EYE" GRB 080319B WITH THE IceCube NEUTRINO TELESCOPE2009In: Astrophysical Journal, ISSN 0004-637X, E-ISSN 1538-4357, Vol. 701, no 2, 1721-1731 p.Article in journal (Refereed)
    Abstract [en]

    We report on a search with the IceCube detector for high-energy muon neutrinos from GRB 080319B, one of the brightest gamma-ray bursts (GRBs) ever observed. The fireball model predicts that a mean of 0.1 events should be detected by IceCube for a bulk Lorentz boost of the jet of 300. In both the direct on-time window of 66 s and an extended window of about 300 s around the GRB, no excess was found above background. The 90% CL upper limit on the number of track-like events from the GRB is 2.7, corresponding to a muon neutrino fluence limit of 9.5 x 10(-3) erg cm(-2) in the energy range between 120 TeV and 2.2 PeV, which contains 90% of the expected events.

    Extending the Search for Neutrino Point Sources with IceCube above the Horizon2009In: Physical Review Letters, ISSN 0031-9007, Vol. 103, no 22, Article ID: 221102- p.Article in journal (Refereed)
    Abstract [en]

    Point source searches with the IceCube neutrino telescope have been restricted to one hemisphere, due to the exclusive selection of upward going events as a way of rejecting the atmospheric muon background. We show that the region above the horizon can be included by suppressing the background through energy-sensitive cuts. This improves the sensitivity above PeV energies, previously not accessible for declinations of more than a few degrees below the horizon due to the absorption of neutrinos in Earth. We present results based on data collected with 22 strings of IceCube, extending its field of view and energy reach for point source searches. No significant excess above the atmospheric background is observed in a sky scan and in tests of source candidates. Upper limits are reported, which for the first time cover point sources in the southern sky up to EeV energies.

    Calibration and characterization of the IceCube photomultiplier tube2010In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, Vol. 618, no 1-3, 139-152 p.Article in journal (Refereed)
    Abstract [en]

    Over 5000 PMTs are being deployed at the South Pole to compose the IceCube neutrino observatory. Many are placed deep in the ice to detect Cherenkov light emitted by the products of high-energy neutrino interactions, and others are frozen into tanks on the surface to detect particles from atmospheric cosmic ray showers. IceCube is using the 10-in. diameter R7081-02 made by Hamamatsu Photonics. This paper describes the laboratory characterization and calibration of these PMTs before deployment. PMTs were illuminated with pulses ranging from single photons to saturation level. Parameterizations are given for the single photoelectron charge spectrum and the saturation behavior. Time resolution, late pulses and afterpulses are characterized. Because the PMTs are relatively large, the cathode sensitivity uniformity was measured. The absolute photon detection efficiency was calibrated using Rayleigh-scattered photons from a nitrogen laser. Measured characteristics are discussed in the context of their relevance to IceCube event reconstruction and simulation efforts. (C) 2010 Elsevier B.V. All rights reserved.

    Measurement of sound speed vs. depth in South Pole ice for neutrino astronomy2010In: Astroparticle physics, ISSN 0927-6505, E-ISSN 1873-2852, Vol. 33, no 5-6, 277-286 p.Article in journal (Refereed)
    Abstract [en]

    We have measured the speed of both pressure waves and shear waves as a function of depth between 80 and 500 m depth in South Pole ice with better than 1% precision. The measurements were made using the South Pole Acoustic Test Setup (SPATS), an array of transmitters and sensors deployed in the ice at the South Pole in order to measure the acoustic properties relevant to acoustic detection of astrophysical neutrinos. The transmitters and sensors use piezoceramics operating at similar to 5-25 kHz. Between 200 m and 500 m depth, the measured profile is consistent with zero variation of the sound speed with depth, resulting in zero refraction, for both pressure and shear waves. We also performed a complementary study featuring an explosive signal propagating vertically from 50 to 2250 m depth, from which we determined a value for the pressure wave speed consistent with that determined for shallower depths, higher frequencies, and horizontal propagation with the SPATS sensors. The sound speed profile presented here can be used to achieve good acoustic source position and emission time reconstruction in general, and neutrino direction and energy reconstruction in particular. The reconstructed quantities could also help separate neutrino signals from background. (C) 2010 Elsevier B.V. All rights reserved.

    First Neutrino Point-Source Results from the 22 String Icecube Detector2009In: The Astrophysical Journal Letters, ISSN 2041-8205, Vol. 701, no 1, L47-L51 p.Article in journal (Refereed)
    Abstract [en]

    We present new results of searches for neutrino point sources in the northern sky, using data recorded in 2007-2008 with 22 strings of the IceCube detector (approximately one-fourth of the planned total) and 275.7 days of live time. The final sample of 5114 neutrino candidate events agrees well with the expected background of atmospheric muon neutrinos and a small component of atmospheric muons. No evidence of a point source is found, with the most significant excess of events in the sky at 2.2σ after accounting for all trials. The average upper limit over the northern sky for point sources of muon-neutrinos with E –2 spectrum is ##IMG## [http://ej.iop.org/images/1538-4357/701/1/L47/apjl318527ieqn1.gif] $E^2\,Φ _ν _μ < 1.4 \,\,\times\,\, 10^-11\; \mathrmTeV\;cm^-2\;\mathrms^-1$ , in the energy range from 3 TeV to 3 PeV, improving the previous best average upper limit by the AMANDA-II detector by a factor of 2.

    Limits on a Muon Flux from Neutralino Annihilations in the Sun with the IceCube 22-String Detector2009In: Physical Review Letters, ISSN 0031-9007, Vol. 102, no 20, Article ID: 201302- p.Article in journal (Refereed)
    Abstract [en]

    A search for muon neutrinos from neutralino annihilations in the Sun has been performed with the IceCube 22-string neutrino detector using data collected in 104.3 days of live time in 2007. No excess over the expected atmospheric background has been observed. Upper limits have been obtained on the annihilation rate of captured neutralinos in the Sun and converted to limits on the weakly interacting massive particle (WIMP) proton cross sections for WIMP masses in the range 250-5000 GeV. These results are the most stringent limits to date on neutralino annihilation in the Sun.

    Determination of the atmospheric neutrino flux and searches for new physics with AMANDA-II2009In: Physical Review D, ISSN 1550-7998, E-ISSN 1550-2368, Vol. 79, no 10, Article ID: 102005- p.Article in journal (Refereed)
    Abstract [en]

    The AMANDA-II detector, operating since 2000 in the deep ice at the geographic South Pole, has accumulated a large sample of atmospheric muon neutrinos in the 100 GeV to 10 TeV energy range. The zenith angle and energy distribution of these events can be used to search for various phenomenological signatures of quantum gravity in the neutrino sector, such as violation of Lorentz invariance or quantum decoherence. Analyzing a set of 5511 candidate neutrino events collected during 1387 days of livetime from 2000 to 2006, we find no evidence for such effects and set upper limits on violation of Lorentz invariance and quantum decoherence parameters using a maximum likelihood method. Given the absence of evidence for new flavor-changing physics, we use the same methodology to determine the conventional atmospheric muon neutrino flux above 100 GeV.

    Search for point sources of high energy neutrinos with final data from AMANDA-II2009In: Physical Review D, ISSN 1550-7998, E-ISSN 1550-2368, Vol. 79, no 6, Article ID: 062001- p.Article in journal (Refereed)
    Abstract [en]

    We present a search for point sources of high energy neutrinos using 3.8 yr of data recorded by AMANDA-II during 2000-2006. After reconstructing muon tracks and applying selection criteria designed to optimally retain neutrino-induced events originating in the northern sky, we arrive at a sample of 6595 candidate events, predominantly from atmospheric neutrinos with primary energy 100 GeV to 8 TeV. Our search of this sample reveals no indications of a neutrino point source. We place the most stringent limits to date on E(-2) neutrino fluxes from points in the northern sky, with an average upper limit of E(2)Phi(nu mu)+nu(tau)<= 5.2x10(-11) TeV cm(-2) s(-1) on the sum of nu(mu) and nu(tau) fluxes, assumed equal, over the energy range from 1.9 TeV to 2.5 PeV.

    Solar Energetic Particle Spectrum on 2006 December 13 Determined by IceTop2008In: The Astrophysical Journal Letters, Vol. 689, no 1, L65-L68 p.Article in journal (Refereed)
    Abstract [en]

    On 2006 December 13 the IceTop air shower array at the South Pole detected a major solar particle event. By numerically simulating the response of the IceTop tanks, which are thick Cerenkov detectors with multiple thresholds deployed at high altitude with no geomagnetic cutoff, we determined the particle energy spectrum in the energy range 0.6-7.6 GeV. This is the first such spectral measurement using a single instrument with a well-defined viewing direction. We compare the IceTop spectrum and its time evolution with previously published results and outline plans for improved resolution of future solar particle spectra.

    The IceCube data acquisition system: Signal capture, digitization, and timestamping2009In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, Vol. 601, no 3, 294-316 p.Article in journal (Refereed)
    Abstract [en]

    IceCube is a km-scale neutrino observatory under construction at the South Pole with sensors both in the deep ice (InIce) and on the surface (IceTop). The sensors, called Digital Optical Modules (DOMs). detect, digitize and timestamp the signals from optical Cherenkov-radiation photons. The DOM Main Board (MB) data acquisition subsystem is connected to the central DAQ in the IceCube Laboratory (ICL) by a single twisted copper wire-pair and transmits packetized data on demand. Time calibration is maintained throughout the array by regular transmission to the DOMs of precisely timed analog signals, synchronized to a central GPS-disciplined clock. The design goals and consequent features, functional capabilities, and initial performance of the DOM MB, and the operation of a combined array of DOMs as a system, are described here. Experience with the first InIce strings and the IceTop stations indicates that the system design and performance goals have been achieved. (c) 2009 Elsevier B.V. All rights reserved.

    Konsten att paketera sig själv: - Kommunikationsstrategier för personligt varumärkesbyggande i sociala medier2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Målet med denna uppsats var att undersöka vilka kommunikativa strategier personer inom PR- och informationsbranschen arbetar efter för att bygga upp och stärka sina personliga varumärken i sociala medier. Studiens huvudfråga lyder ”Vilka kommunikativa strategier använder människor inom PR- och informationsbranschen för att stärka sitt personliga varumärkesbyggande i sociala medier?”. Syftet med studien var tudelat, dels ville vi bidra med djupare förståelse kring vad det finns för drivkrafter bakom personligt varumärkesbyggande i sociala medier och dels ville vi bidra med nya infallsvinklar och ett nytt empiriskt material till den samhällsvetenskapliga forskningsfronten.

    Studiens teoretiska ramverk utgår från varumärkesteori, Erving Goffmans teori om självpresentation samt Pierre Bourdieus teori om kapital och social positionering. Studien är genomförd med kvalitativa metoder, för det första har vi tagit del av aktuell forskning på områdena sociala medier och personligt varumärkesbyggande, vi har även gjort en innehållslig kartläggning av tio digitala personliga varumärken samt genomfört intervjuer med personerna bakom varumärkena. När vi i uppsatsen använder begreppet sociala medier syftar vi enbart på bloggar och microbloggverktyget Twitter.

    Resultatet för denna studie visar att respondenternas strategier för digitalt personligt varumärkesbyggande skiljer sig åt, strategierna skiljer sig även beroende på socialt medium. Somliga respondenter uppger att de genomgående arbetar strategiskt både på Twitter och med sin blogg medan andra menar att de inte har några strategier alls. Oavsett hur stort utrymme de strategiska baktankarna får går det att skönja likheter i samtliga respondenters varumärkesbyggande. Utifrån dessa likheter har vi identifierat fem idealnormer och strategier för personligt varumärkesbyggande för personer verksamma inom PR- och informations-branschen: att tydligt identifiera sin yrkesidentitet och sina personliga egenskaper, att utelämna privat och ofördelaktig information, att skriva om ett avgränsat ämnesområde, att visa på aktualitet och kunskap inom branschen samt att nätverka med personer inom branschen. Dessa har legat till grund när vi konstruerat följande tre idealtyper för respondenternas varumärkesbyggande: reporter, kommentator och kåseriskribent.

    Sammanfattningsvis har vi kunnat konstatera att personligt varumärkesbyggande i sociala medier tillskrivs allt större värde inom PR- och informationsbranschen. Värdet ligger i möjligheten att stärka sin position i förhållande till andra inom branschen, för att lyckas med detta krävs en utmejslad strategi och kunskap om hur man på bästa sätt paketerar sig själv.

    Simulation of 3ph induction motor in Matlab with Direct and Soft starting methods.2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Asynchronous machines are considered nowadays the most commonly used electrical machines, which are mainly used as electrical induction motors. Starting the induction motor is the most important and dangerous step. The theory behind this project is based on representing the real motor by a set of equations and values in Matlab using the subsystem feature, forming a corresponding idealistic motor in a way where all the physical effects are similar. The motor is started under different loads in two methods: Direct and Soft starting. Each method is studied and discussed using supporting simulation of currents, torque, speed, efficiency and power factor curves.

    Overcoming social constraints for immigrantentrepreneurs in Sweden2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Entrepreneurship is in full-swing across the globe and it is widely regarded as a sustainable solution to long-unresolved economic issues like unemployment and poverty. Immigration is also a growing reality and the immigrating individuals can contribute to the new societies either by settling for a job or launching a business as an entrepreneur and in turn creating more jobs. However, social constraints are a key hurdle in the way of immigrant entrepreneurs. This paper aims to not only understand the social constraints faced by immigrant entrepreneurs but also provide a set of guidelines on how to overcome these social constraints. A qualitative research study focused on immigrant entrepreneurs in Sweden was designed around this purpose and was conducted in two cities of Sweden. Entrepreneurs in the study were from diverse nationalities of origin and business sectors. Key social constraints identified through the study are cultural differences, differences in business practices, and language – all acting as a wall for foreign entrepreneurs. Networking – both business and social – is regarded as the main solution to overcome these barriers and the weight for this lies equally on state, entrepreneurship industry, and the immigrant entrepreneurs. Immigrant entrepreneurs can overcome the social constraints by also researching their business area in detail as well as marketing themselves and their businesses especially by establishing a strong and trustable social media profile. Government needs to recognize the diversity of immigrant entrepreneurship communities and create tailor-made social interaction programs for different nationalities, educational backgrounds, and business sectors. It can also project positive image of successful immigrant entrepreneurs not only to inspire other immigrant entrepreneurs but also to increase trust regarding immigrant entrepreneurs among native population. Another important step by government could be early orientation for immigrant entrepreneurs to Swedish business market. Entrepreneurship advisory industry needs to understand immigrant entrepreneurs better and organize more multi-cultural events to lower the barriers between native and immigrant communities.

    Hur skiljer sig traditionella från nyare generationer antipsykotika åt vad gäller biverkningen viktökning?2008Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpStudent thesis
    Abstract [sv]

    Antipsykotiska läkemedel är basen för behandling av schizofreni, en psykisk sjukdom som uppträder redan hos unga människor. Symtomen vid schizofreni brukar delas in i positiva symtom (hallucinationer, vanföreställningar, paranoida tankar), negativa symtom (koncentrationssvårigheter, nedsatt språk- och tankeförmåga, minskat intresse för omgivningen, och initiativlöshet), samt kognitiva symtom (minnesproblem, problem med uppmärksamhet och koncentration).

    Antipsykotiska läkemedel delas in i typiska (den äldre generationen) och atypiska (den nyare generationen) antipsykotika. För båda grupperna antipsykotiska läkemedel finns det risk för biverkningar. De vanligaste biverkningarna vid behandling med den äldre generationen antipsykotika är extrapyramidala biverkningar. En biverkning som förefaller mer specifik för de nya atypiska preparaten är viktökning, vilken även kan orsaka utveckling av många allvarliga sjukdomstillstånd.

    Syftet med detta arbete var att jämföra typiska och atypiska antipsykotiska läkemedel med avseende på utveckling av viktökning.

    För att få svar på min frågeställning har en litteraturstudie av fem vetenskapliga artiklar genomförts. De vetenskapliga artiklarna har hittats genom databassökningar i PubMed, medan övriga fakta har hämtats från andra källor.

    Resultatet av de vetenskapliga artiklarna visar att det finns skillnader mellan traditionella och nyare generationer antipsykotika vad gäller tendens att orsaka viktökning. Med några undantag, är flera antipsykotiska läkemedel, som tillhör den nyare generationen, associerade med högre risk för utveckling av viktökning jämfört med den äldre generationen antipsykotika. Viktökning orsakas mest av klozapin, följt av olanzapin och risperidon. Quetiapin orsakar, i likhet med haloperidol, mindre viktökning.

    På grund av detta faktum, forskar man numera kring orsakerna till denna skillnad för att förbättra biverkningsprofilen hos framtida antipsykotika.

    First limits on the very-high energy gamma-ray afterglow emission of a fast radio burst HESS observations of FRB 1504182017In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 597, A115Article in journal (Refereed)
    Abstract [en]

    Aims. Following the detection of the fast radio burst FRB150418 by the SUPERB project at the Parkes radio telescope, we aim to search for very-high energy gamma-ray afterglow emission. Methods. Follow-up observations in the very-high energy gamma-ray domain were obtained with the H.E.S.S. imaging atmospheric Cherenkov telescope system within 14.5 h of the radio burst. Results. The obtained 1.4 h of gamma-ray observations are presented and discussed. At the 99% C.L. we obtained an integral upper limit on the gamma-ray flux of Phi(gamma)(E > 350 GeV) < 1.33 x 10(-8) m(-2) s(-1). Differential flux upper limits as function of the photon energy were derived and used to constrain the intrinsic high-energy afterglow emission of FRB 150418. Conclusions. No hints for high-energy afterglow emission of FRB 150418 were found. Taking absorption on the extragalactic background light into account and assuming a distance of z = 0 : 492 based on radio and optical counterpart studies and consistent with the FRB dispersion, we constrain the gamma-ray luminosity at 1 TeV to L < 5 : 1 x 10(47) erg/s at 99% C.L.

    HESS Limits on Linelike Dark Matter Signatures in the 100 GeV to 2 TeV Energy Range Close to the Galactic Center2016In: Physical Review Letters, ISSN 0031-9007, E-ISSN 1079-7114, Vol. 117, no 15, 151302Article in journal (Refereed)
    Abstract [en]

    A search for dark matter linelike signals iss performed in the vicinity of the Galactic Center by the H.E.S.S. experiment on observational data taken in 2014. An unbinned likelihood analysis iss developed to improve the sensitivity to linelike signals. The upgraded analysis along with newer data extend the energy coverage of the previous measurement down to 100 GeV. The 18 h of data collected with the H.E.S.S. array allow one to rule out at 95% C.L. the presence of a 130 GeV line (at l = -1.5 degrees, b = 0 degrees and for a dark matter profile centered at this location) previously reported in Fermi-LAT data. This new analysis overlaps significantly in energy with previous Fermi-LAT and H.E.S.S. results. No significant excess associated with dark matter annihilations was found in the energy range of 100 GeV to 2 TeV and upper limits on the gamma-ray flux and the velocity weighted annihilation cross section are derived adopting an Einasto dark matter halo profile. Expected limits for present and future large statistics H.E.S.S. observations are also given.

    Gamma-ray blazar spectra with HESS II mono analysis: The case of PKS2155-304 and PG1553+1132017In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 600, A89Article in journal (Refereed)
    Abstract [en]

    Context. The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment's sensitivity to lower energies. The lowest energy threshold is obtained using monoscopic analysis of data taken with CT5, providing access to gamma-ray energies below 100 GeV for small zenith angle observations. Such an extension of the instrument's energy range is particularly beneficial for studies of active galactic nuclei with soft spectra, as expected for those at a redshift >= 0.5. The high-frequency peaked BL Lac objects PKS 2155-304 (z = 0.116) and PG 1553 + 113 (0.43 < z < 0.58) are among the brightest objects in the gamma-ray sky, both showing clear signatures of gamma-ray absorption at E > 100 GeV interpreted as being due to interactions with the extragalactic background light (EBL). Aims. The aims of this work are twofold: to demonstrate the monoscopic analysis of CT5 data with a low energy threshold, and to obtain accurate measurements of the spectral energy distributions (SED) of PKS 2155-304 and PG 1553 + 113 near their SED peaks at energies approximate to 100 GeV. Methods. Multiple observational campaigns of PKS 2155 304 and PG 1553 + 113 were conducted during 2013 and 2014 using the full H.E.S.S. II instrument (CT1-5). A monoscopic analysis of the data taken with the new CT5 telescope was developed along with an investigation into the systematic uncertainties on the spectral parameters which are derived from this analysis. Results. Using the data from CT5, the energy spectra of PKS 2155 304 and PG 1553 + 113 were reconstructed down to conservative threshold energies of 80 GeV for PKS 2155 304, which transits near zenith, and 110 GeV for the more northern PG 1553 + 113. The measured spectra, well fitted in both cases by a log-parabola spectral model ( with a 5.0 similar to statistical preference for non-zero curvature for PKS 2155 304 and 4.5 sigma for PG 1553+113), were found consistent with spectra derived from contemporaneous Fermi-LAT data, indicating a sharp break in the observed spectra of both sources at E approximate to 100 GeV. When corrected for EBL absorption, the intrinsic H.E.S.S. II mono and Fermi-LAT spectrum of PKS 2155 304 was found to show significant curvature. For PG 1553+113, however, no significant detection of curvature in the intrinsic spectrum could be found within statistical and systematic uncertainties.
