    A summary and appraisal of existing evidence of antimicrobial resistance in the Syrian conflict2018In: International Journal of Infectious Diseases, ISSN 1201-9712, E-ISSN 1878-3511, Vol. 75, p. 26-33Article, review/survey (Refereed)
    Abstract [en]

    Antimicrobial resistance (AMR) in populations experiencing war has yet to be addressed, despite the abundance of contemporary conflicts and the protracted nature of twenty-first century wars, in combination with growing global concern over conflict-associated bacterial pathogens. The example of the Syrian conflict is used to explore the feasibility of using existing global policies on AMR in conditions of extreme conflict. The available literature on AMR and prescribing behaviour in Syria before and since the onset of the conflict in March 2011 was identified. Overall, there is a paucity of rigorous data before and since the onset of conflict in Syria to contextualize the burden of AMR. However, post onset of the conflict, an increasing number of studies conducted in neighbouring countries and Europe have reported AMR in Syrian refugees. High rates of multidrug resistance, particularly Gram-negative organisms, have been noted amongst Syrian refugees when compared with local populations. Conflict impedes many of the safeguards against AMR, creates new drivers, and exacerbates existing ones. Given the apparently high rates of AMR in Syria, in neighbouring countries hosting refugees, and in European countries providing asylum, this requires the World Health Organization and other global health institutions to address the causes, costs, and future considerations of conflict-related AMR as an issue of global governance.

    Antimicrobial resistance in the context of the Syrian conflict: Drivers before and after the onset of conflict and key recommendations2018In: International Journal of Infectious Diseases, ISSN 1201-9712, E-ISSN 1878-3511, Vol. 73, p. 1-6Article, review/survey (Refereed)
    Abstract [en]

    Current evidence describing antimicrobial resistance (AMR) in the context of the Syrian conflict is of poor quality and sparse in nature. This paper explores and reports the major drivers of AMR that were present in Syria pre-conflict and those that have emerged since its onset in March 2011. Drivers that existed before the conflict included a lack of enforcement of existing legislation to regulate over-the-counter antibiotics and notification of communicable diseases. This contributed to a number of drivers of AMR after the onset of conflict, and these were also compounded by the exodus of trained staff, the increase in overcrowding and unsanitary conditions, the increase in injuries, and economic sanctions limiting the availability of required laboratory medical materials and equipment. Addressing AMR in this context requires pragmatic, multifaceted action at the local, regional, and international levels to detect and manage potentially high rates of multidrug-resistant infections. Priorities are (1) the development of a competent surveillance system for hospital-acquired infections, (2) antimicrobial stewardship, and (3) the creation of cost-effective and implementable infection control policies. However, it is only by addressing the conflict and immediate cessation of the targeting of health facilities that the rehabilitation of the health system, which is key to addressing AMR in this context, can progress.

    The European Union’s Technological and Economic Development: A Study on Production of Renewable Energy2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis answer the two main questions, firstly, the role of technological development in the production of RE with special reference to investment subsidy in supporting schemes and research and development (R&D). Investment subsidies in supporting schemes and R&D are widely used to promote RE technology and considered economical, efficient instruments than regulation approach. Secondly, the study investigates the relationship between the production of RE and the economic development. Panel data for twelve European Union (EU) countries are analysed for the period 1990 to 2013. The study uses a Cobb Douglas production function to estimate the EU's rational behaviour of investment subsidy between supporting schemes and R&D. For the estimation techniques, the study uses the unit root test, cointegration test, and dynamic pooling average group (PMG) model. The selection of the PMG model is based on the results of diagnostic tests, i.e. cross-sectional dependence, heteroskedasticity, serial correlation, and Hausman. Furthermore, the cointegration test confirms that in the long-run all the variables move together to achieve equilibrium. The PMG model confirms the effect of the independent variables on the dependent variable. Thus, it is concluded that the investment subsidies in supporting schemes have a positive and significant effect on the production of renewable energy in the long-run. However, the investment subsidy in research and development also has a positive but insignificant effect on the production of renewable energy in the long-run. Based on the long-run result, thus the study suggests that it is more rational to invest subsidy in supporting schemes than in R&D. In order to find the relationship between the production of RE and economic development, the result of the study confirms that economic development has a positive and significant impact on the production of renewable energy both in the short-and long-run. In addition, the test of the causality confirms the bidirectional relationship between production of RE and economic development. The bidirectional relationship states that both energy and economic growth are associated and complement each other.

    Dietary vitamin D intake and risk of type 2 diabetes in the European Prospective Investigation into Cancer and Nutrition: the EPIC-InterAct study2014In: European Journal of Clinical Nutrition, ISSN 0954-3007, E-ISSN 1476-5640, Vol. 68, no 2, p. 196-202Article in journal (Refereed)
    Abstract [en]

    BACKGROUND/OBJECTIVES: Prospective cohort studies have indicated that serum vitamin D levels are inversely related to risk of type 2 diabetes. However, such studies cannot determine the source of vitamin D. Therefore, we examined the association of dietary vitamin D intake with incident type 2 diabetes within the European Prospective Investigation into Cancer and Nutrition (EPIC)-InterAct study in a heterogeneous European population including eight countries with large geographical variation.

    SUBJECTS/METHODS: Using a case-cohort design, 11 245 incident cases of type 2 diabetes and a representative subcohort (N = 15 798) were included in the analyses. Hazard ratios (HR) and 95% confidence intervals (CIs) for type 2 diabetes were calculated using a Prentice-weighted Cox regression adjusted for potential confounders. Twenty-four-hour diet-recall data from a subsample (N = 2347) were used to calibrate habitual intake data derived from dietary questionnaires.

    RESULTS: Median follow-up time was 10.8 years. Dietary vitamin D intake was not significantly associated with the risk of type 2 diabetes. HR and 95% CIs for the highest compared to the lowest quintile of uncalibrated vitamin D intake was 1.09 (0.97-1.22) (P-trend = 0.17). No associations were observed in a sex-specific analysis. The overall pooled effect (HR (95% CI)) using the continuous calibrated variable was 1.00 (0.97-1.03) per increase of 1 mg/day dietary vitamin D.

    CONCLUSIONS: This observational study does not support an association between higher dietary vitamin D intake and type 2 diabetes incidence. This result has to be interpreted in light of the limited contribution of dietary vitamin D on the overall vitamin D status of a person.

    Dietary intake of vitamin D and calcium and breast cancer risk in the European prospective investigation into cancer and nutrition2013In: Nutrition and Cancer, ISSN 0163-5581, E-ISSN 1532-7914, Vol. 65, no 2, p. 178-187Article in journal (Refereed)
    Abstract [en]

    Studies assessing the effects of vitamin D or calcium intake on breast cancer risk have been inconclusive. Furthermore, few studies have evaluated them jointly. This study is the largest so far examining the association of dietary vitamin D and calcium intake with breast cancer risk in the European Prospective Investigation into Cancer and Nutrition. During a mean follow-up of 8.8 yr, 7760 incident invasive breast cancer cases were identified among 319,985 women. Multivariable Cox proportional hazards regression was used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for pre- and postmenopausal breast cancer risk. Comparing the highest with the lowest quintile of vitamin D intake, HR and 95% CI were 1.07 (0.87-1.32) and 1.02 (0.90-1.16) for pre- and postmenopausal women, respectively. The corresponding HR and 95% CIs for calcium intake were 0.98 (0.80-1.19) and 0.90 (0.79-1.02), respectively. For calcium intake in postmenopausal women, the test for trend was borderline statistically significant (P(trend) = 0.05). There was no significant interaction between vitamin D and calcium intake and cancer risk (P(interaction) = 0.57 and 0.22 in pre- and postmenopausal women, respectively). In this large prospective cohort, we found no evidence for an association between dietary vitamin D or calcium intake and breast cancer risk.

    Ethnobotanical survey of medicinally important wild edible fruits species used by tribal communities of Lesser Himalayas-Pakistan2013In: Journal of Ethnopharmacology, ISSN 0378-8741, E-ISSN 1872-7573, Vol. 148, no 2, p. 528-536Article in journal (Refereed)
    Abstract [en]

    Ethnopharmacological relevance: Present survey was conducted to explore ethnomedicinal uses and cultural importance of wild edible fruits species by the inhabitants of Lesser Himalayas-Pakistan. Materials and methods: Information was obtained through informed consent semi-structured interviews, questionnaires, market survey, focus group conversation, unceremonious dialogue and village walks with key informants. Cultural significance of each species was calculated based on use report by participants at each study site. Results: A total of 35 wild edible fruits belonging to 21 genera and 17 families were used for the treatment of various ailments and consumed. Rosaceae was found dominating family with (8 spp.), followed by Moraceae (6 spp.), Rhamnaceae (5 spp.), Palmae and Vitaceae (2 spp. each) and remaining families were represented by one species each. Fruits (48%) were found highly utilized plant parts, followed by leaves (34%), bark, flowers and seeds (4% each), branches, latex and roots (2% each). Water was used as a medium for preparation while milk, ghee, oil, egg and butter are used for application. Modes of preparation were fall into seven categories like fresh parts eaten raw (38%), powder (24%), decoction (20%), extract (12 %), paste (4%), juice and latex (2% each). Based on cultural important index (CI) Morus nigra was found most significant species within top ten fruit plants followed by Morus alba, Olea ferruginea, Berberis lycium, Pyrus pashia, Ficus carica, Ficus palmata, Ziziphus mauritiana, Diospyros lotus and Ziziphus nummularia. Conclusions: Traditional uses of wild edible plant depend mainly on socio-economic factors rather than climatic conditions or wealth of flora. Use reports and citation demonstrated that there is a common cultural heritage regarding the gathered food plants. Further investigation is required for Antioxidant study, essential and toxic components, pharmacological applications; dietary requirements and biotechnological techniques to improve yields.

    Test of Rapid Control System Development using TargetLink2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is to employ and evaluate an evaluation board with the standard microprocessor freescale MPC5554EVB board for implementation of control algorithms which are created in Matlab/Simulink instead of using dSPACE prototyping hardware. The Simulink real-time model shall be compiled to the MPC5554EVB board. TargetLink is a powerful software tool which allows an automatic generation of efficient C code from Simulink and facilitates model-based control design. The goal of this thesis is to learn how to use TargetLink in a control design workflow from model to real code and what are the limitations of a microprocessor platform and to evaluate the capabilities of TargetLink to generate a working code for a generic microprocessor.

    Biomass offsets little or none of permafrost carbon release from soils, streams, and wildfire: an expert assessment2016In: Environmental Research Letters, ISSN 1748-9326, E-ISSN 1748-9326, Vol. 11, no 3, article id 034014Article in journal (Refereed)
    Abstract [en]

    As the permafrost region warms, its large organic carbon pool will be increasingly vulnerable to decomposition, combustion, and hydrologic export. Models predict that some portion of this release will be offset by increased production of Arctic and boreal biomass; however, the lack of robust estimates of net carbon balance increases the risk of further overshooting international emissions targets. Precise empirical or model-based assessments of the critical factors driving carbon balance are unlikely in the near future, so to address this gap, we present estimates from 98 permafrost-region experts of the response of biomass, wildfire, and hydrologic carbon flux to climate change. Results suggest that contrary to model projections, total permafrost-region biomass could decrease due to water stress and disturbance, factors that are not adequately incorporated in current models. Assessments indicate that end-of-the-century organic carbon release from Arctic rivers and collapsing coastlines could increase by 75% while carbon loss via burning could increase four-fold. Experts identified water balance, shifts in vegetation community, and permafrost degradation as the key sources of uncertainty in predicting future system response. In combination with previous findings, results suggest the permafrost region will become a carbon source to the atmosphere by 2100 regardless of warming scenario but that 65%-85% of permafrost carbon release can still be avoided if human emissions are actively reduced.

    Cavity-enhanced optical frequency comb spectroscopy of high-temperature H2O in a flame2014In: Optics Express, ISSN 1094-4087, E-ISSN 1094-4087, Vol. 22, no 11, p. 13889-13895Article in journal (Refereed)
    Abstract [en]

    We demonstrate near-infrared cavity-enhanced optical frequency comb spectroscopy of water in a premixed methane/air flat flame. The detection system is based on an Er:fiber femtosecond laser, a high finesse optical cavity containing the flame, and a fast-scanning Fourier transform spectrometer (FTS). High absorption sensitivity is obtained by the combination of a high-bandwidth two-point comb-cavity lock and auto-balanced detection in the FTS. The system allows recording high-temperature water absorption spectra with a resolution of 1 GHz and a bandwidth of 50 nm in an acquisition time of 0.4 s, with absorption sensitivity of 4.2 x 10 (9) cm(-1) Hz(-1/2) per spectral element.

    Socionomstudenters välbefinnande: En studie om studenternas psykosociala välbefinnande vid Umeå Universitet2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Studien syftade till att kartlägga och beskriva hur det psykosociala välbefinnandet såg ut bland socionomstudenterna vid Umeå universitet.  Tidigare forskning visar på att nedsatt välbefinnande är vanligt bland studenter.  Genom att undersöka studenternas psykosociala studiesituation i relation till deras subjektiva och objektiva välbefinnande kartlades en bild av hur det ser ut på socionomprogrammet. Studien omfattar alla campusstuderande terminer vid Umeå universitet. Krav-, kontroll- och stödmodellen har använts för att beskriva studenternas psykosociala arbetsmiljö och General Health Questionnaire 12 (GHQ-12) användes för att mäta studenternas välbefinnande. En enkät skickades ut till samtliga studenter, vilken innehöll kvantitativa och kvalitativa inslag. Resultaten visar att 47,2% av studenterna har ett nedsatt välbefinnande samt att 64,2 % upplevde lätta eller svåra upplevelser av ångest, oro eller ängslan. Majoriteten av studenterna hade besvär med sömnen och visade på trötthetstecken som huvudvärk samt upplevde stress i relation till sina studier. Ju högre stress studenten upplever desto sämre välbefinnande. Studenterna visade på högt eget inflytande över sina studier (94,6%) samt att de kan hantera de krav som ställs på dem (97,3%).

    Vad är rättvisa?: En undersökning om vem eller vilka Platons teori riktar sig till2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Plato´s Republic is maybe the most widely read philosophical work of all times. It is the earliest surviving, systematic utopia in Europe´s history and continues to inspire people today. But who did Plato want to address with his work and why? In this paper I will discuss these issues. My thesis is that Plato wanted to direct his Republic to people, men and women, who have a good character and love wisdom in order to make them to think radically differently from the traditional norms. If these would-be philosophers could challenge the old-fashioned way of seeing things they could take the lead to establish a just society. I will also discuss critically two alternative approaches from other philosophers.

    Det digitala gränssnittet i en restaurangverksamhet: En fallstudie om utmaningar och möjligheter när det digitala gränssnittet ersätter det mänskliga gränssnittet2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Digitalization has increased over the past decade and changed our ways of solving problems. Studies have shown that digitalization has made a dramatic change in our lives and it's a huge challenge for government, organization, company and citizens. In about 15 years half of today's job will be disappears and will be replaced by digitalization, automatization and robotization. The purpose of the study is to describe and create an understanding of the new digital service that has been implemented in restaurant businesses, a new way of interaction between customers and company. A literature study has been made to give a fair picture of the theory and interviews with the purpose to gathering new information on how the digital restaurant works and get the knowledge of efficiency in business. Qualitative material has been analyzed and compared to theories from the literature study. The results of the study showed that there is immense difference between the employees view and company view of digital service in restaurant.

    Ion-acoustic solitary waves in a dense pair-ion plasma containing degenerate electrons and positrons2008In: Physics Letters A, ISSN 0375-9601, E-ISSN 1873-2429, Vol. 372, no 22, p. 4057-4061Article in journal (Refereed)
    Abstract [en]

    Fully nonlinear propagation of ion-acoustic solitary waves in a collisionless dense/quantum electron-positron-ion plasma is investigated. The electrons and positrons are assumed to follow the Thomas-Fermi density distribution and the ions are described by the hydrodynamic equations. An energy balance-like equation involving a Sagdeev-type pseudo-potential is derived. Finite amplitude solutions are obtained numerically and their characteristics are discussed. The small-but finite-amplitude limit is also considered and an exact analytical solution is obtained. The present studies might be helpful to understand the excitation of nonlinear ion-acoustic solitary waves in a degenerate plasma such as in superdense white dwarfs.

    Localized electrostatic excitations in a Thomas-Fermi plasma containing degenerate electrons2008In: Physics of Plasmas, ISSN 1070-664X, E-ISSN 1089-7674, Vol. 15, no 5, article id 052303Article in journal (Refereed)
    Abstract [en]

    By using the Thomas-Fermi electron density distribution for quantum degenerate electrons, the hydrodynamic equations for ions, and the Poisson equation, planar and nonplanar ion-acoustic solitary waves in an unmagnetized collisionless plasma are investigated. The reductive perturbation method is used to derive cylindrical and spherical Korteweg-de Vries equations. Numerical solutions of the latter are presented. The present results can be useful in understanding the features of small but finite amplitude localized ion-acoustic solitary pulses in a degenerate plasma.

    Market efficiency for two classes of stocks in China: state owned and private companies2012Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The fast-growing economy in China attracts the world’s interests, which includes the Chinese stock markets. The market efficiency of Chinese stock markets is widely discussed by researchers in different approaches. The involvement of government in stock markets is a unique case in the financial world.

     

    By this paper, we are answering the question that is the degree of market efficiency of stat-owned companies different from that of private companies in Chinese stock markets. This will bring us knowledge about Chinese stock markets as well as the impact from ownership, market value and management styles on market efficiency.

     

    To clarify the influence from government involvement in stock markets, we select 938 stocks distinguished by ownership structure. This quantitative study is preceded on daily data from 2007 to 2011. We use auto correlation, Chi-square test, and linear regression together with Spearman’s correlation to test our hypothesis. The degree of market efficiency of each ownership group is examined and compared to each other. Market efficiency related to ownership and market capitalization are inspected if they are anomaly factors in Chinese markets.

     

    The empirical results indicate that the degree of market efficiency of state-owned companies is significantly different from the degree of market efficiency of private-owned companies in China. The market capitalization is one of the existing anomaly factors in Chinese stock markets, as well as it is correlated with degree of market efficiency to some extent. For state-owned enterprises, active management on stock market does not provide a better market efficiency compared to passively managed companies.

    A Design Research Lab—An Integrated Model to Identify Conscious and Unconscious Behavior in the Design Process2016In: Proceedings of the AHFE 2016 International Conference on Design for Inclusion, July 27-31, 2016, Walt Disney World®, Florida, USA: Advances in Design for Inclusion, Springer International Publishing Switzerland, 2016Conference paper (Refereed)
    Abstract [en]

    To understand how different design solutions affect users, designers traditionally use different evaluation methods that mainly rely on conscious feedback from the users. However, the complexity of human behaviour, where a large part is unconscious, point to a need for an extended tool box addressing the part not accessible to human conscious knowledge. Here, we describe a design research lab where traditional methods are complemented with tools to measure physiological signals influenced by emotional and sympathetic responses. These tools include galvanic skin response (GSR), electrocardiograph (ECG), and electroencephalograph (EEG). Typical sessions with acquired data of conscious and unconscious user reactions are described. The large body of data collected, which also require non-design expertise for interpretation, suggest that a further development towards simplified output data of the unconscious reactions is needed to allow wider use within industrial design work.

    Development of breath sampling system for detection of exhaled nitric oxide by Faraday modulation spectroscopy2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Technological developments over the years have resulted in many different techniques for detection of nitric oxide (NO) in both the atmosphere and from biological sources. One such technique is Faraday Modulation Spectroscopy (FAMOS), which is a laser-based spectroscopic technique for detection of paramagnetic molecules in gas phase. The technique uses a modulated magnetic field that introduce rotation of the polarization plane of linearly polarized laser light, which can be related to the concentration of the molecules. This enables sensitive and selective detection of paramagnetic gaseous compounds and the technique is thus well suited for detection of NO for biomedical applications in low concentrations which is essential for breath analysis.

    In this thesis, a system for breath analysis is developed and coupled to a Faraday modulation spectrometer for sensitive detection of NO at 5.33 μm based on a room temperature continuous wave distributed feedback (DFB) QCL. It also provides a theoretical model of FAMOS utilizing the most sensitive Q3/2 (3/2 ) transition in NO. The results from this study indicate that the mid-infrared FAMOS system, which was built around a continuous wave (cw) quantum cascade laser (QCL) emitting light with an output power of approximately 70 mW, is fully capable of detection of ppb levels of NO in exhaled human breath.

    Realization of an instrumentation for detection of acetylene in breath by the NICE-OHMS technique2014Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Measurement is an important activity in nearly all branches of science and technology. A measurement technique provides an observer with a numerical value corresponding to the variable being measured. Researchers envision that laser spectroscopy will serve as a functional tool for measurement to detect molecules in gas phase. One such a laser spectroscopic technique for measurement is noise-immune cavity enhanced optical heterodyne molecular spectroscopy (NICE-OHMS), which is a highly sensitive laser-based spectroscopic technique for detection of molecules in gas phase. The technique was developed in the mid-1990s at the Joint Institute for Laboratory Astrophysics (JILA).

    In this thesis, a realization of instrumentation for detection of acetylene in breath by a fiber laser-based NICE-OHMS instrumentation working in the near-infrared wavelength region is obtained. The results of this study show that the NICE-OHMS system is fully capable of detection of parts-per-billion (ppb) levels of acetylene in exhaled human breath.

    Optimering av kortaste vägen vid hantering och avledning av skadligt dagvatten: Lösning med A-stjärna algoritm samt en guide med ekonomiska styrmedel för beslutsfattande aktörer2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The earth's population is growing and increasingly more people move into urban areas. This means that as cities grow, new buildings are being built and infrastructures are expanding. This rapid growth is directly related to increased floods as a result of man-made changes in nature.

    The already overloaded storm water systems for rain-, melt-, rinsing and other surplus water cannot often handle the existing demand. Therefore, floods arise at greater rain intensity and pose significant costs to society. Due to an unclear division of responsibility within the municipality's organizations there is a failure to handle the existing storm water problem. In order to be able to plan for sustainable cities in the future, it is important to find a viable solution regarding the responsibility issue and how to best handle the storm water to achieve cost advantage.

    This study presents a guide for municipalities on how to allocate the responsibility between the municipality and the exploiter. The guide is based on simulations and theories in optimization to propose effective solutions for harmful surplus storm water. Through simulations of the storm water system, the amount of surplus water that does not fit the storm water system capacity has been quantified. In addition, to find a reasonable alternative run-off path for the surplus water, different methods of the shortest path problem have been investigated.

    The results show that a classical shortest path algorithm with a heuristic function is not the most appropriate alternative. This because the heuristic function in the algorithm prevents the selection of a more natural pathway upstream even though it could be a more optimal solution.

    Företagsamt förhållningssätt genom entreprenörskapsutbildning?: En kvalitativ studie om hur elevers företagsamma förhållningssätt kan utvecklas genom entreprenörskapsutbildning på gymnasieskolan2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det har på senare tid växt fram en rad olika entreprenörskapsutbildningar i det svenska utbildningsväsendet och det verkar som att satsningarna på den här typen av utbildningar kommer att fortsätta att öka. Detta relativt nya sociala fenomen i det svenska utbildningsväsendet innebär att många elever och lärare i dagsläget har genomgått någon formav entreprenörskapsutbildning. Frågan som jag vill kasta ljus på i den här studien är: Hur utvecklas elevers företagsamma förhållningssätt genom entreprenörskapsutbildning?

    Till min hjälp har jag använt mig av en kvalitativ metod där jag har intervjuat elever och lärare som genomgått entreprenörskapsutbildningen Ung Företagsamhet. Jag har fördjupat mig i tre av dessa elever och en av lärarna. Ett aktörssynsätt utifrån ett bottom-up perspektiv används för att besvara studiens forskningsfråga och syfte. Vidare används en multipel fallstudie där jag analyserar varje fall var för sig och avslutar sedan med en jämförande analys mellan fallen från vilken slutsatserna dras.

    Det teoretiska ramverket fungerar som teoretiska utgångspunkter och innehåller begrepp och modeller från teorier om entreprenörskap och lärande. Dessa teoretiska utgångspunkter har utvecklats utifrån studiens angreppssätt som är abduktion eller den gyllene medelvägen. Centrala teoretiska begrepp som används i studien är lärandesituation, lärandeprocesser och lärandenivåer vilka sammanfattar studiens teoretiska referensram.

    Det huvudsakliga syftet med studien är att baserat på det teoretiska ramverket bidra med djupare förståelse för hur elevers företagsamma förhållningssätt kan utvecklas genom entreprenörskapsutbildning. Slutsatserna för denna studie är att utvecklingen av ett företagsamt förhållningssätt bestäms av olika inre och yttre lärvillkor i lärandesituationen. Lärandeprocesserna för de olika aktörerna kategoriserades som kognitiva (kunskapsmässiga), psykodynamiska (emotionella) och sociala (samarbetsmässiga). Lärandenivåerna som berördes av eleverna kategoriserades som: know-me, know-what, know-when, know-how, know-who och know-why.

    Social Entrepreneurship: A Case Study of SIFE Umeå University2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today the world faces a lot of societal challenges in the economical, social and environmental spheres that needs to be overcome. Global warming, poverty and increasing economic inequality are only some of these challenges. The public debate has been focused on finding solutions to them and one of these has been addressed as social entrepreneurship. This phenomenon is about the era of the new type of entrepreneurs – social entrepreneurs – that recognize these challenges as opportunities that can be exploited in a both profitable and sustainable manner. Social entrepreneurship has in this way emerged as an interesting phenomenon and a new area in the entrepreneurship research.

     

    This study examines the phenomenon of social entrepreneurship by scrutinizing the concept SIFE - Students In Free Enterprise. SIFE is a non-profit organization that claims to be actively engaged in working with social entrepreneurship. The general purpose of this study is to bring a deeper understanding of the social entrepreneurship phenomenon, by describing the particular purpose, the case of SIFE Umeå University as a social entrepreneurship model. Our study is a qualitative case study using semi-structured interviews. Six respondents have been interviewed from different levels of the organization - SIFE Umeå University - in order to reflect the entire organization. We have used a deductive approach by establishing a theoretical framework that guided the interviews and has been used in the analysis of the empirical data.

     

    The main conclusions in this study show that SIFE Umeå University’s work with social entrepreneurship is mainly about socioeconomic and personal development. Another conclusion is that cooperation with partners from different sectors of the society is an important fundament in their work with social entrepreneurship. Furthermore, SIFE Umeå University can be considered as hybrid of a voluntary organization and social enterprise since it includes similarities of both organizational forms. Moreover, the study shows that entrepreneurial skills play an important role in SIFE Umeå University’s work with social entrepreneurship. Finally, we can from this study draw the conclusion that SIFE Umeå University’s work with social entrepreneurship can be divided in six steps: Target group, Job/life training, Commercial enterprises, Personal development, Socioeconomic development, Partnership Network.

    Storytelling Practices in Project Management: Exploratory study in new business process implementation in Information and Communication Technology projects2017Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Stories have always been present in the life of people as a part of their culture, it is a rather ancient narrative technique. The message delivered in a form of a story is specifically appealing to listeners, which makes it a powerful communication tool. The thesis explores storytelling practices in project management by answering the question: “How project managers use storytelling in new business process implementation in ICT projects?” The choice of the topic was driven by the gap in the literature and the choice of context was chosen by the level of maturity of project management in ICT industry. Within the framework of interpretivist research paradigm, the data was collected by interviewing ten project managers of new business process implementation in ICT projects.

    The thesis findings suggest that storytelling in implementation of new business processes in ICT projects is used in formal and informal forums in written and verbal format. Project managers use storytelling to pursue several goals: making sense of ICT projects, human resource management, promoting adaptation to new business processes, knowledge management and attracting new customers and investments into ICT projects. Storytelling in ICT projects is also limited by storytelling conditions, such as organizational culture, extent of change, governance structure. Storytelling in projects is subject to challenges, such as logistics and timeliness of practices.

    From the practical point of view, the thesis explores storytelling as an effective communication tool that can be used for multiple goals in project management. It allows adding storytelling to the requirement list of new soft competences of project managers. The thesis has bridged a literature gap between storytelling and project management, which opens new theoretical perspective of interpreting the reality in projects and creates space for further research.

    Dynamiskt Mindset i Förskolan2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studie behandlar begreppen dynamiskt mindset, grit och motivation som nyligen varit fokuserade i forsknings- och undervisningssammanhang, och kunskaperna bland förskollärare kring dessa begrepp. Studiens avsikt var att undersöka vad ett dynamiskt mindset kan innebära för förskollärare och sedan i sin tur hur det kan påverka deras elever. Detta omfattar hur förskollärare och elever kan utveckla sitt dynamiska mindset. Studien bygger på en kvalitativ metod och utgår ifrån semistrukturerade intervjuer med fem förskollärare från olika förskolor. Resultaten visar att förskollärarna är positivt inställda till att utveckla ett arbetssätt med att lära ut dynamiskt mindset inom förskolan och en därmed få en tydligare pedagogik. Resultaten visar även att förskollärares pedagogiska kompetens skulle gynnas av en läroplan som visar tydligare riktlinjer kring hur barn ska motiveras, hur de ska arbeta med barns inspiration till ett dynamiskt mindset. Slutsatsen innefattar bland annat att mer forskning kring studiens begrepp behövs i samband med förskolans värld. Och att förskolepedagogiken i sam-band med begreppen dynamiskt mindset, grit och motivation behövs för en förbättring av läroplanen för förskolan. Detta kan göras ihop med förskollärarutbildning och en utökad återkoppling för examinerade förskollärare.

    Contamination Controls for Root Canal Sample Analysis by Molecular Methods: A pilot study.2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    When exploring the root canal flora, before and after treatment, it is crucial to eliminate bacteria from the tooth surface before entering the pulp. If not, bacteria from the surface might contaminate the root canal sample resulting in false information. When using molecular techniques, not only bacteria are to be eliminated but also DNA from bacteria to avoid contamination from the surface. The aim of the study was to examine if DNA from bacteria can be eliminated using a modified disinfection protocol. Samples from the tooth surface were taken from ten intact teeth stored in ethanol/ glycerol (50 % / 50 %) prior to the experiment. The teeth were sampled before and after cleaning the surface with H2O2 (30 %), NaOCl (3 %) and EDTA (0.5 M). Samples were taken from buccal, occlusal and lingual enamel and dentin surfaces. All samples were analyzed with polymerase chain reaction and culture. In a second experiment, ten teeth were placed in a bacterial solution containing Enterococcus faecalis for three days and sampled as above. No growth could be detected using the conventional culture technique from the post-wash samples. The results show that the teeth could not entirely become free from bacterial DNA using the performed cleaning routine as all samples were positive for bacterial DNA after cleaning. The average amount of detectable bacterial DNA was decreased with 95 % after the cleaning procedure. The results confirm reduction of bacterial DNA after cleaning, however, detectable bacterial DNA is still evident after disinfection.

    Drawing a framework from agency theory, we use a panel data design to examine the factors motivating the level of demand for reinsurance in the rapidly developing Swedish property fire insurance market during the interwar period 1919–39. We find that as hypothesised, reinsurance enabled Swedish fire insurers to mitigate underwriting and solvency risks and thus increased their capacity to underwrite new business in uncertain economic times. This in turn helped to increase the supply of indemnity coverage for property (buildings) fire risks in the Swedish insurance market. We also find that as expected, investment earnings are inversely related to reinsurance purchases. However, contrary to what was hypothesised, reinsurance appears to be positively related to liquidity levels, suggesting that over our period of analysis, fire insurers could have been reinsuring to ‘protect’ earnings and accumulated cash reserves therefore enabling investment opportunities to be realised. Analysis of the sub-period 1919–28 further supports this contention, while our results for the economic depression years after 1929 show that reinsurance helped mitigate underwriting and insolvency risks, suggesting that the reinsurance decision of fire insurance companies could be motivated by macroeconomic factors.

    Farmaceut-patientkommunikation på öppenvårdsapotek i Kurdistan: En observationsstudie som undersöker i vilken omfattning apotekspersonalen informerar om läkemedelsanvändningen och dess verkan.2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Apotekens riktlinjer har utvecklats från att ha begränsat farmaceuter ideras utdelning av medicin till att ge råd eller erbjuda rådgivning om patientens medicinering. Det är viktigt att farmaceuter ger rådgivning kring patienters medicinering då det ger effektivt behandlingsresultat, ökad följsamhet och minskar konfusion och osäkerhet hos patienten. Studier har visat att den farmaceutiska rådgivningen varierar mycket på apotek. En svensk studie har visat att samtalet mellan farmaceut och patient fokuserar mer på ekonomi och regelverk än att ge farmaceutiskrådgivning. Det har tidigare inte gjorts studier på hur kommunikation samt den farmaceutiska rådgivningen fungerar i mellanöstern.

    Syfte: Syftet med den här studien är att undersöka kommunikationen mellan farmaceut och patient på öppenvårdsapotek i Kurdistan, Irak. Kommunikationen kommer att undersökas utifrån hur lång tid patientmötena tar och innehåll. Det som studeras är i vilken utsträckning apotekspersonalen konsulterar patienter samt den information som tillhandahålls till patienterna ur ett farmaceutiskt perspektiv.

    Metod: En kvantitativ och icke- deltagande observationsstudie där patientmöten observerades utifrån innehåll och tidsmätning av mötet. Observatören bockade avämnen som tas upp under mötet utefter en empirisk fastställd observationsmall.

    Resultat: 4 apotek deltog i studien och det gjordes sammanlagt 90 observationer varav 85 stycken inkluderades i studien. Apotekmiljön har en negativ påverkan på patientmötena, exempelvis att det saknas ett avskilt ställe för ett privatsamtal medpatienter, bullret i omgivningen och dålig organiserad läkemedel. Den stora delen av den medicinska konsulteringen är information om administrering, lite om läkemedelsverkan och nästan inget om biverkningar. Det icke-medicinska innehållet var frågor om pris och tillgänglighet av läkemedel.

    Diskussion: Det finns säkert många anledningar för varför kommunikationen inte är fokuserad på konsultering till patienter. En orsak kan vara otillräcklig kunskap bland informatörerna som konsultering kring biverkningar och läkemedels verkan exkluderas i kommunikationen. En annan förklaring kan vara att rådgivningen tar mer tid och at tapoteksägare upplever rådgivning som en dyr tjänst och av den anledningen inteprioriterar sin uppmärksamhet på läkemedelsrådgivning. Försäljningen som uppenbarligen inte ligger i att ge läkemedelsrådgivning till patienterna.

    Slutsats: Den här observationsstudien visade att mycket lite tid (medeltid 125,5 smin7 s/max 427 s) tillägnas till rådgivning kring patientens medicinering. Läkemedel är en stor behandlingsmetod inom hälso- och sjukvården av den orsaken borde farmaceutisk rådgivning vara tillgänglig för personer som besöker apotek. Resultatet avden här studien visar att dagens patientmöten på öppenvårdapotek i Kurdistan inte fokuserar på konsultering kring läkemedel. Eventuellt kommer patienten inte få ett nyttigt behandlingsresultat.

    Abstract [en]

    We extend an algorithm by Paige and Tarjan that solves the coarsest stable refinement problem to the domain of trees. The algorithm is used to minimize nondeterministic tree automata (NTA) with respect to bisimulation. We show that our algorithm has an overall complexity of $O(\hat{r} m \log n)$, where $\hat{r}$ is the maximum rank of any symbol in the input alphabet, m is the total size of the transition table, and n is the number of states.

    Quantum Chemical Designing of Efficient Sensitizers for Dye Sensitized Solar Cells2013In: Bulletin of the Korean Chemical Society (Print), ISSN 0253-2964, E-ISSN 1229-5949, Vol. 34, no 7, p. 2093-2098Article in journal (Refereed)
    Abstract [en]

    Density functional theory (DFT) was used to determine the ground state geometries of indigo and new design dyes (IM-Dye-1 IM-Dye-2 and IM-Dye-3). The time dependant density functional theory (TDDFT) was used to calculate the excitation energies. All the calculations were performed in both gas and solvent phase. The LUMO energies of all the dyes were above the conduction band of TiO2, while the HOMOs were below the redox couple (except IM-Dye-3). The HOMO-LUMO energy gaps of new design dyes were smaller as compared to indigo. All new design dyes were strongly red shifted as compared to indigo. The improved light harvesting efficiency (LHE) and free energy change of electron injection Delta G(inject) of new designed sensitizers revealed that these materials would be excellent sensitizers. The broken coplanarity between the benzene near anchoring group having LUMO and the last benzene attached to TPA unit in all new design dyes consequently would hamper the recombination reaction. This theoretical designing will the pave way for experimentalists to synthesize the efficient sensitizers for solar cells.

    High weak order methods for stochastic differential equations based on modified equations2012In: SIAM Journal on Scientific Computing, ISSN 1064-8275, E-ISSN 1095-7197, Vol. 34, no 3, p. A1800-A1823Article in journal (Refereed)
    Abstract [en]

    Inspired by recent advances in the theory of modified differential equations, we propose a new methodology for constructing numerical integrators with high weak order for the time integration of stochastic differential equations. This approach is illustrated with the constructions of new methods of weak order two, in particular, semi-implicit integrators well suited for stiff (mean-square stable) stochastic problems, and implicit integrators that exactly conserve all quadratic firstintegrals of a stochastic dynamical system. Numerical examples confirm the theoretical results and show the versatility of our methodology.

    Energieffektivisering vid renovering av Lamellhus på Mariehemsvägen2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In Sweden more houses than ever before are being built, and the house production is moving forward. At the same time, awareness of the energy use of buildings and its accompanying impacts on climate and sustainability are increasing. Therefore, Boverket constantly raises the demands for the energy performance of newly built and refurbished buildings.

    According to current requirements from Boverket (BBR, 2017), the primary energy value for apartment buildings may not be more than 85 kWh per square meter of tempered floor space and year. This also applies according to future requirements in 2021, but with the difference that the average U-value will decrease from 0.4 to 0.35 W/m2 K which means that apartment buildings must be built in an efficient way to reduce energy use. A large part of new construction and newly refurbished apartment buildings must then implement energy efficiency measures on their buildings to meet future requirements.

    This degree project has been carried out in collaboration with Rikshem AB who wants to investigate the impact of various energy efficiency measures on their apartment building ”Lamellhus”. The aim is to theoretically reduce apartment buildings ”Lamellhusets” specific energy use from 187,4 to 70 kWh/m2 Atemp, year and thus reduce the primary energy enough to meet future requirements according to BBR near-zero energy building.

    To theoretically reduce specific energy use and thus primary energy value, the project through manual calculations and with the help of computer tools examined various energy efficiency measures on the building's construction and installation system.

    The results show that the measures on the property climate shell are sufficient to meet the requirements. If all the measures according to package 1 or 2 on the design are combined, specific energy use according to BBR 16 (2010) will be at 83-94 kWh/m2 Atemp, year and the primary energy value according to BBR 25 (2017) will be at 68-77 kWh/m2 Atemp, year.

    The results also show how much of a building's energy use is ventilated. Replacing the ventilation system from F-systems to FTX-systems on the reference house in the base case, is the measure that gives one of the greatest impacts with a heat saving of (25.5-26.7%). In combination FTX-system with district heating, specific energy consumption can be reduced as low as possible. If the operation with the FTX-system is applied together with the existing district heating and all measures on the construction according to package 1 or 2, this gives a reduction of approximately (70-75 %) compared to the base case corresponding to 42-51 kWh/m2 Atemp, year according to BBR 16 and according to BBR 25, the figures are even lower. If the calculation considers thermal bridges and air leakage in the house, the result will increase.

    The results also show that the investment repays itself after 15-16 years with a simplified payback. With a calculation rate of 5 %, it is profitable over 30-31 years or more, but with a calculation rate of 8 % it is not profitable.

    Bring Your Body into Action: Body Gesture Detection, Tracking, and Analysis for Natural Interaction2014Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Due to the large influx of computers in our daily lives, human-computer interaction has become crucially important. For a long time, focusing on what users need has been critical for designing interaction methods. However, new perspective tends to extend this attitude to encompass how human desires, interests, and ambitions can be met and supported. This implies that the way we interact with computers should be revisited. Centralizing human values rather than user needs is of the utmost importance for providing new interaction techniques. These values drive our decisions and actions, and are essential to what makes us human. This motivated us to introduce new interaction methods that will support human values, particularly human well-being.

    The aim of this thesis is to design new interaction methods that will empower human to have a healthy, intuitive, and pleasurable interaction with tomorrow’s digital world. In order to achieve this aim, this research is concerned with developing theories and techniques for exploring interaction methods beyond keyboard and mouse, utilizing human body. Therefore, this thesis addresses a very fundamental problem, human motion analysis.

    Technical contributions of this thesis introduce computer vision-based, marker-less systems to estimate and analyze body motion. The main focus of this research work is on head and hand motion analysis due to the fact that they are the most frequently used body parts for interacting with computers. This thesis gives an insight into the technical challenges and provides new perspectives and robust techniques for solving the problem.
