    Administrative reform – Arguments and Values2008Book (Other academic)
    Abstract [en]

    Internationalisation of regional development policies – Needs and demands in the Nordic countries. All eight Nordic countries and self-governing areas have recently discussed or are currently discussing their administrative structures, i.e. how many municipalities or regions there should be and what responsibilities they should have. Denmark has already implemented a reform, Finland has begun to do so and, Greenland will soon follow. The experience has however been rather less successful in Norway and Sweden where many years of study and discussion now seem to have been more or less wasted.This report describes the processes and the discourse of administrative reform with a particular focus on the arguments used and the values that lie behind these arguments. The discourses are mainly concerned with four types of arguments relating to democracy, efficiency, regional development and the reform process itself. The arguments used, it is argued here, are mainly prophesies about the future. This forward-looking political logic is rather different from the work undertaken by research-based inquiries where future direction is sought in past experiences. The current report is part of Nordregio's research programme, Internationalisation of regional development policies – needs and demands in the Nordic countries. The analysis of events and developments has been updated to June 2008.

    Development of an Efficient G-Quadruplex-Stabilised Thrombin-Binding Aptamer Containing a Three-Carbon Spacer Molecule2017In: ChemBioChem (Print), ISSN 1439-4227, E-ISSN 1439-7633, Vol. 18, no 8, p. 755-763Article in journal (Refereed)
    Abstract [en]

    The thrombin-binding aptamer (TBA), which shows anticoagulant properties, is one of the most studied G-quadruplex-forming aptamers. In this study, we investigated the impact of different chemical modifications such as a three-carbon spacer (spacer-C3), unlocked nucleic acid (UNA) and 3′-amino-modified UNA (amino-UNA) on the structural dynamics and stability of TBA. All three modifications were incorporated at three different loop positions (T3, T7, T12) of the TBA G-quadruplex structure to result in a series of TBA variants and their stability was studied by thermal denaturation; folding was studied by circular dichroism spectroscopy and thrombin clotting time. The results showed that spacer-C3 introduction at the T7 loop position (TBA-SP7) significantly improved stability and thrombin clotting time while maintaining a similar binding affinity as TBA to thrombin. Detailed molecular modelling experiments provided novel insights into the experimental observations, further supporting the efficacy of TBA-SP7. The results of this study could provide valuable information for future designs of TBA analogues with superior thrombin inhibition properties. © 2017 The Authors.

    Språkbarriärer och tolkanvändning i vården ur sjuksköterskans perspektiv: En litteraturöversikt2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: During 2014 over 200 different languages were spoken in Sweden, and by the end of 2017 approximately 20 % of the population was foreign born. 110 000 healthcare injuries, many of them due to failure in communication were reported by the nursing association (2017). The evident language barriers create a lack of trust and confidence between patient and nurse. To overcome the identified language barriers interpreters have become a necessary tool in order to exchange information and create a trusting relationship between patients and nurses.

    Aim: To explore the nurses experiences and perceptions of existing language barriers and the use of interpreters within healthcare.

    Method: A literature review of fifteen scientific articles. These were identified in the databases PubMed and Cinahl through searches for relevant articles with appropriate keywords.

    Results: Nurses consider language barriers to be the biggest obstacle to good communication, which often lead to misunderstandings and misinterpretations. The identified problem of communication is experienced as time consuming and the nurses perceive more planning to be needed when dealing with patients with a different mother tongue. Furthermore, it presents a severe challenge to maintain good care and establish an understanding of the patient’s story. Nurses prefer to use an interpreter on site, however interpreters by phone are more accessible. More than one underlying cause is linked to nurse’s skepticism to use interpreters. To mention one many nurses doubt the accuracy of the interpretation. Moreover, nurses acknowledge their need of further training and education in the use of interpreters.

    Conclusion: The result identified is based upon nurse’s first hand experiences of language barriers and the use of interpreters. The literature review has provided insightful knowledge and increased the understanding of language barriers and the use of interpreters in health care. The research will be an asset in future careers and provide help in overcoming set problem.

    Human Factors Approach for Maintenance Improvement2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The purpose of this research work is to explore and describe human factors affectingmaintenance execution. To achieve the purpose of this study, the influencing factors have been identified using a literature survey. They have been categorized into four main groups namely organizational, workplace, job and individual factors. The Analytical Hierarchy Process (AHP) method is employed on data questionnaires to rank the priority of the factors. The interrelationships between these factors have been recognized by theInterpretive Structural Modelling (ISM) model. In the present case studies, MICMAC1analysis technique is also implemented for identifying the driving, dependent, linkage and autonomous factors. The data was collected through a questionnaire survey involving the participation of 16 and 25 maintenance staff and 10 mining experts in Swedish and Iranian mines, respectively. Within the study, it has been identified that the temperature, work layout, tools design and tools availability are the most important factors in both mines related to these categories. However, the significant factors in the organizational and individual categories are different in the selected mines. The effect of workplace factors on the maintainability of mining equipment is discussed and thereafter a methodology for maintainability management in the design and operation phases is developed. In the thirdcase study HEART2 is applied to estimate the probability of human error occurring duringmaintenance execution in an Iranian cable company. This research supports maintenance management to gain knowledge of human factors that affect maintenance execution. Further, this understanding could be useful in the development of strategies to improve the execution of maintenance.Keywords: Human Factors, Maintenance Management, Human Reliability, HumanPerformance, AHP, ISM, MICMAC, HEART

    Human reliability assessment (HRA) in maintenance of production process: a case study2016In: International Journal of Systems Assurance Engineering and Management, ISSN 0975-6809, E-ISSN 0976-4348, Vol. 7, no 2, p. 229-238Article in journal (Refereed)
    Abstract [en]

    Human reliability makes a considerable contribution to the maintenance performance, safety, and cost-efficiency of any production process. To improve human reliability, the causes of human errors should be identified and the probability of human errors should be quantified. Analysis of human error is very case-specific; the context of the field should be taken into account. The aim of this study is to identify the causes of human errors and improve human reliability in maintenance activities in the cable manufacturing industry. The central thrust of this paper is to employ the three most common HRA techniques—human error assessment and reduction technique, standardized plant analysis risk-human reliability, and Bayesian network—for estimating human error probabilities and then to check the consistency of the results obtained. The case study results demonstrated that the main causes of human error during maintenance activities are time pressure, lack of experience, and poor procedure. Moreover, the probabilities of human error, obtained by employing the three techniques, are similar and consistent

    Abstract [en]

    As equipment becomes more complex, repair process becomes more complicated, costly and time-consuming. Maintainability principles are developed to facilitate the repair process. Maintainability principles are applied in design phase and they are characteristic that affects time, accuracy, ease and safety requirements of the repair process. Considering Maintainability principles in the design phase are critical in challenging operational conditions such as Arctic offshore. To have an effective design for maintainability a systematic management approach is required during the design phase. This paper is developed a systematic guideline for maintainability management as an engineering discipline for challenges operational condition

    Abstract [en]

    Some industries such as mining industry create complex and challenging work place for maintenance crews. For example in an underground mine, for some machines, heavy maintenance tasks must be performed on site in a limited workspace in a harsh environment, including dust and improper illumination. Such operating conditions can increase the health, safety, and environment (HSE) risk, reduce the availability of the machines and increase the life cycle cost of equipment. A review of current mining equipment design and maintenance procedure confirms that considerable reduction in HSE risk, as well as substantial cost savings, can be achieved by considering human factors. This study discusses the effect of workplace factors on the maintainability of mining equipment. It presents the results from questionnaires on the effect of work place factors on maintainability performance given to maintenance staff at two mines, one in northern Sweden and the other in Iran.

    ”Ingen gillar kyckling så mycket!": Hur en grupp ungdomar, boende på ett ungdomshem, upplever sin mat- och måltidssituation.2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: På Statens institutionsstyrelses (SiS) särskilda ungdomshem bor ungdomar med psykosociala problem, till exempel missbruk och kriminalitet. Ungdomar som är omhändertagna och får vård mot sin vilja befinner sig i en komplex situation. Då dessa människor inte har stor möjlighet att påverka sin mat- och måltidssituation kan det vara intressant att undersöka hur de upplever denna.

    Syfte: Syftet med uppsatsen var att undersöka intagna ungdomars upplevelse av sin mat- och måltidssituation vid boende på ungdomshem.

    Metod: En semistrukturerad intervjustudie med en framtagen intervjuguide genomfördes på ett statligt ungdomshem i Mellansverige. Sju personer intervjuades. Intervjuerna analyseras med hjälp av kvalitativ innehållsanalys.

    Resultat: Analysen resulterade i tre huvudsakliga teman: Maktlöshet och missnöje, Måltider – källa till gemenskap och otrygghet och Matens roll i relationen till personalen. Informanterna upplevde ett missnöje gällande maten som serverades på institutionen. De ansåg framförallt att variationen av maträtter var otillräcklig. Vidare upplevdes måltidssituationen stundtals som otrygg då den delades med andra avdelningar på institutionen. Att personalen ibland använde maten som ett verktyg för bestraffning samt ansågs vara otydliga i sin kommunikation upplevdes som problematiskt.

    Slutsats: Att vara frihetsberövad innebär en begränsning av självbestämmandet. Denna form av boendesituation kräver en struktur av rutiner och fasta tidpunkter för att fungera och det är obestridligt att självbestämmandet är mindre än vid ett liv i frihet. Dock bör myndigheten eventuellt överväga att till viss del öka graden av inflytande från ungdomarna, i syfte att skapa en bättre mat- och måltidsupplevelse för ungdomarna som bor på deras institutioner.

    Customer value creation in technology based restaurant experiences: Case study in the mobile application restaurant: Pincho’s2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the restaurant industry, there is a growing interest in applying technology as part of the service process. However, the constant development of technological innovations does not always meet the demand and therefore it would be important to empirically study how the technology based dining experiences are perceived by the customer. Accordingly, collecting information on how the service quality is perceived when technology is playing a major role during the restaurant experience is important, since such research has not been conducted before. Hereby, the aim of this research paper is to examine restaurant experiences from the customer point of view, in which the role of service personnel is reduced due to implementation of a mobile application. In order to achieve this aim, the objective is to identify what creates value for the customers in a mobile application generated dining experience. Thus, following research questions were stated: How does the customers perceive the service quality in a mobile application generated dining experience? and What are the advantages and disadvantages for the customer to use mobile application for the service delivery during the dining experience?

    The research used explanatory sequential mixed methods. Primarily, the researchers performed collection and analysis of quantitative data. Additionally, to get a profound interpretation of the research topic, qualitative data was gathered and analyzed. Thereafter, the qualitative data was used for explaining the quantitative findings more in detail. For the sake of this, the research questions were divided correspondingly one for each method. Findings from the descriptive quantitative analysis, indicated that the use of mobile application for the service delivery was mostly positively perceived. Additionally, discourse analysis was conducted from 812 Pincho’s associated TripAdvisor online reviews. The review findings provided more detailed opinions of the customers’ experiences in their own words and brought up possible advantages and disadvantages.

    The research findings can provide a small contribution to the knowledge of technology based restaurant experiences. However, as the researchers collected only a small amount of primary data, the validity of the results is limited. Additionally, using online reviews is a highly subjective method and consequently has its shortcomings. Therefore, in order to gain thorough understanding of mobile application generated dining experiences, the phenomenon should be further examined in a larger scale. Together with this, it would be intriguing to conduct a questionnaire based survey in all the Pincho’s restaurants and more specifically examine overall satisfaction of the customers.

    Women, Entrepreneurship and Social Capital: A Dialogue and Construction2008Collection (editor) (Other academic)
    Abstract [en]

    This book explores social capital as the multiple relationships between gender, management and entrepreneurship. Human resources are the social capital of a firm and business life, based on trust as well as on expertise, values and cultural diversity. This calls for cross-cultural knowledge and an understanding of gender issues and individual differences in the social capital of the firm and society. The dialogue between women entrepreneurship and social capital theory and research has its special place among other women entrepreneurship books, the number of which has lately increased. It strengthens still in some respect the fragmented voice of women entrepreneurship research by providing a landscape of women entrepreneurs as creators of, and created by, social capital. It indicates how women entrepreneurs appear to have a special position in forming, developing and reorganizing the social capital in the business world. In its eleven chapters, twenty-six researchers representing a variety of disciplines from different parts of the world are presenting findings on diverse aspects of the dialogue between women entrepreneurship and social capital. As a consequence the central concepts, social capital, entrepreneurship and gender, are given a variety of meanings. Women entrepreneurs and business owners regardless of their cultural context, branch and education provide interesting ideas to the global debate on equality and social capital.

    Incentives and Inequalities in Family and Working Life2018Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Essay I: Same-gender teachers may affect educational preferences by acting as role models for their students. I study the importance of the gender composition of teachers in math and science during lower secondary school on the likelihood to continue in math-intensive tracks in the next levels of education. I use population wide register data from Sweden and control for family fixed effects to account for sorting into schools. According to my results, the gender gap in graduating with a math-intensive track in upper secondary school would decrease by 16 percent if the share of female math and science teachers would be changed from none to all at lower secondary school. The gap in math-related university degrees would decrease by 22 percent from the same treatment. The performance is not affected by the higher share of female science teachers, only the likelihood to choose science, suggesting that the effects arise because female teachers serve as role models for female students.

    The (in)effectiveness of financial incentive on fertility behaviour: Childcare –a safety net for children?2017Licentiate thesis, monograph (Other academic)
    Abstract [en]

    Is childcare a safety net for vulnerable children? This paper investigates the role of childcare for the health outcomes of children whose parents are unemployed. Exploiting time variation in childcare access resulting from a reform requiring Swedish municipalities to provide childcare also for children with unemployed parents, we estimate causal effects on health, as measured by register data on hospitalizations. We find that access to childcare reduced hospitalizations for infections among toddlers, especially among boys. Among children in preschool age access to childcare caused a temporary increase in hospitalization for infections the year they got access to childcare.

    Childcare - A safety net for children? 2018Report (Other academic)
    Abstract [en]

    We analyze how access to childcare affects health outcomes of children with unemployed parents using a reform that increased childcare access in some Swedish municipalities. For 4–5 year olds, we find an immediate increase in infection-related hospitalization, when these children first get access to childcare. We find no effect on younger children. When children are 10–11 years of age, children who did not have access to childcare when parents were unemployed are more likely to take medication for respiratory conditions. Taken together, our results thus suggest that access to childcare exposes children to risks for infections, but that need for medication in school age is lower for children who had access.

    Automatic Probing System for PCB: Analysis of an automatic probing system for design verification of printed circuit boards2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis is to conduct an analysis of whether the printed circuit boards from Ericsson can be tested using an automatic probing system or what changes in the design are required, to be a viable solution. The main instrument used for analyzing the printed circuit board was an oscilloscope. The oscilloscope was used to get the raw data for plotting the difference between the theoretical and actual signals. Connected to the oscilloscope was a 600A-AT probe from LeCroy. The programs used for interpreting the raw data extracted from the oscilloscope included Python, Matlab and Excel. For simulations on how an extra via in the signal path would affect the end results we used HFSS and ADS. The results were extracted into different Excel sheets to get an easier overview of the results. The results showed that the design of a board must almost become completely rebuilt for the changes, and it is therefore better to implement in a new circuit board rather than in an already existing one. Some of the components have to either be smaller or placed on one side of the board, where they cannot be in the way of the probe. The size of the board will become larger since the rules of via placements will be limited compared to before. The most time demanding part was the simulations of the extra via in the signal path, and the results showed that if a single-ended signal is below two gigahertz the placing of the via does not make a big difference, but if the signal has a higher frequency the placement is mostly dependent on the type of the signal. The optimal placement is generally around four millimeters away from the receiving end.

    Kanalisering och restaurering av vattendrag påverkar mossamhällen i strandzonen: -En studie av Vindelälvens biflöden2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study compared three different types of reaches at streams and how bryophyte species richness, diversity and abundance in the riparian zone differ between them. The different types of reaches are those that have been treated by two types of restoration techniques (best practise and advanced) and streams that have still not been restored (channelized). The bryophytes were gathered from 15 tributaries to Vindelälven, which is in northern Sweden. Bryophyte species richness and diversity was highest at the streams that were still not restored, and I found numerous factors that could explain why this was the case. Fourteen environmental variables were tested against the three bryophyte factors to try to explain the variation found in the study. Time since restoration and the amount of tree biomass in the area could explain the species richness found at the different river types. The study shows that short-term effects of restoration on the riparian zone is a decrease in bryophyte species richness and diversity. However, given enough time the bryophytes are expected to recover in regards to species richness and diversity.

    Brain magnetic resonance imaging does not contribute to the diagnosis of chronic neuroborreliosis2007In: Acta Radiologica, ISSN 0284-1851, E-ISSN 1600-0455, Vol. 48, no 7, p. 755-762Article in journal (Refereed)
    Abstract [en]

    Background: Borrelia infections, especially chronic neuroborreliosis ( NB), may cause considerable diagnostic problems. This diagnosis is based on symptoms and findings in the cerebrospinal fluid but is not always conclusive. Purpose: To evaluate brain magnetic resonance imaging ( MRI) in chronic NB, to compare the findings with healthy controls, and to correlate MRI findings with disease duration. Material and Methods: Sixteen well- characterized patients with chronic NB and 16 matched controls were examined in a 1.5T scanner with a standard head coil. T1- ( with and without gadolinium), T2-, and diffusion- weighted imaging plus fluid- attenuated inversion recovery ( FLAIR) imaging were used. Results: White matter lesions and lesions in the basal ganglia were seen in 12 patients and 10 controls ( no significant difference). Subependymal lesions were detected in patients down to the age of 25 and in the controls down to the age of 43. The number of lesions was correlated to age both in patients ( rho=0.83, P < 0.01) and in controls ( rho=0.61, P < 0.05), but not to the duration of disease. Most lesions were detected with FLAIR, but many also with T2- weighted imaging. Conclusion: A number of MRI findings were detected in patients with chronic NB, although the findings were unspecific when compared with matched controls and did not correlate with disease duration. However, subependymal lesions may constitute a potential finding in chronic NB.

    Learning Playlist Representations for Automatic Playlist Generation2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Spotify is currently the worlds leading music streaming ser-vice. As the leader in music streaming the task of providing listeners with music recommendations is vital for Spotify. Listening to playlists is a popular way of consuming music, but traditional recommender systems tend to fo-cus on suggesting songs, albums or artists rather than pro-viding consumers with playlists generated for their needs.

    This thesis presents a scalable and generalizeable approach to music recommendation that performs song selection for the problem of playlist generation. The approach selects tracks related to a playlist theme by finding the charac-terizing variance for a seed playlist and projects candidate songs into the corresponding subspace. Quantitative re-sults shows that the model outperforms a baseline which is taking the full variance into account. By qualitative results the model is also shown to outperform professionally curated playlists in some cases.

    Innovation Crowdsourcing: Exploring the Use of an Innovation Intermediary2011Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: With the Open Innovation paradigm come new hopes for innovating companies. The ability to tap a global network of experts can, at least in theory, have a significant impact on an organization’s competitive strength. Before such a ‘network of experts’ can be used to its full potential however, a number of challenges related to knowledge markets seem to need solutions. About 10 years ago however, we could witness the entry of a new breed of company – calling themselves innovation intermediaries. These companies are built to profit from delivering the usefulness of knowledge networks to client (Seeker) companies. Though the use of such networks and markets have so far been uncommon outside of high-tech fields they are now starting to be seen used by companies in more mature environments.Purpose: The purpose of this thesis is to examine the collaboration between SCA (a large Swedish corporation) and the innovation intermediary InnoCentive in order to create a better understanding of what kind of benefits can be derived from the use of an innovation intermediary, and how these benefits are best utilized. We also set out to identify relevant limitations of innomediary use and to seek to better understand how using an innomediary can fit a client company’s higher-order activities such as exploration and exploitation.Completion and Results: Our findings include that SCA are using InnoCentive mainly as a tool to solve highly specific problems and/or problems with a low degree of complexity that they encounter in their everyday activities. The challenges related to knowledge markets, we find, are avoided by keeping problem complexity low and problem modularity high for the problems sent out to the network. In addition, InnoCentive’s business model seems to eliminate costly negotiations between Seekers and Solvers. Using this kind of ‘market solution’ however, we argue, will put bounds on the usefulness of the network and makes it mainly suited as a tool for improving an organization’s exploitation capacity.

    Föräldrars upplevelser av omvårdnaden av sitt sent underburna barn på BB: En intervjustudie2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Sent underburna barn vårdas ofta på BB-avdelning för fullgångna barn. De har högre frekvens av återinläggningar på sjukhus än fullgångna barn. De flesta studier kring underburna barns vistelse på sjukhus är inte gjorda specifikt på sent underburna barn. Syfte: Syftet är att utforska föräldrars upplevelser av omvårdnaden av sent underburna barn på en BB-avdelning i Sverige. I analysen användes det teoretiska begreppet empowerment. Metod: Studien är deskriptiv med en kvalitativ ansats. Telefonintervjuer användes som datainsamlingsmetod. Fem mammor och två pappor deltog i studien. Intervjuerna analyserades med innehållsanalys. Resultat/Slutsats: Föräldrarna upplevde att personalen antingen förmedlade empowerment eller inte. Omvårdnadsåtgärder kring barnet som gjorde föräldrarna mer delaktiga upplevdes mer positivt och omvårdnadsåtgärder som orsakade en separation mellan föräldrar och barn upplevdes mer negativt. Föräldrarna hade svårt att ifrågasätta personal, även om de upplevde att något kring omvårdnadsåtgärden kändes fel. Omvårdnadsåtgärder, utfördes inte alltid i enlighet med vetenskap och beprövad erfarenhet. Personalen kan utbildas mer i att främja empowerment i föräldrarollen och därmed även öka föräldradelaktigheten i barnets omvårdnad och möjligheten att se varje familjs unika behov. Mer forskning behövs om hur detta ska ske.

    Comparison of Punching Shear Design Provisions for Flat Slabs2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Abstract

    A new generation of EN 1992-1-1 (2004) also known as Eurocode 2 is under development

    and currently there is a set of proposed provisions regarding section 6.4

    about punching shear, PT1prEN 1992-1-1(2017). It was of interest to compare the

    proposal with the current punching shear design provisions.

    The aim of this master thesis was to compare the punching shear resistance obtained

    in accordance with both design codes. Furthermore the eect of some parameters

    on the resistance was to be compared. It was also of interest to evaluate the userfriendliness

    of the proposal.

    In order to meet the aim, a case study of a real  at slab with drop panels was performed

    together with a parametric study of a pure ctive  at slab. The parametric

    study was performed for inner, edge and corner columns in the cases prestressed,

    without and with shear reinforcement.

    It was concluded that the distance

    av from the column axis to the contra  exural

    location has a big in uence on the punching shear resistance. The factor

    ddg

    considering concrete type and aggregate properties also has a big impact on the resistance.

    The simplied estimation of

    av according to 6.4.3(2) in PT1prEN 1992-1-1

    (2017) may be inaccurate in some cases.

    The length

    b0 of the control perimeter has a larger eect on the resistance in EN

    1992-1-1 (2004) than in PT1prEN 1992-1-1 (2017).

    In PT1prEN 1992-1-1 (2017), studs located outside the second row has no impact

    on the resistance.

    The tensioning force in a prestressed  at slab has a larger in uence on the resistance

    in PT1prEN 1992-1-1 (2017) than in EN 1992-1-1 (2004). Furthermore,

    the reinforcement ratio is increased by the tendons, and thus aect the resistance in

    PT1prEN 1992-1-1 (2017).

    Clearer provisions for the denition of the support strip

    bs for corners and ends

    of walls are needed in PT1prEN 1992-1-1 (2017).

    It may be questionable if the reduction of the perimeter for a large supported area in

    accordance with 6.4.2(4) in PT1prEN 1992-1-1 (2017) underestimates the resistance

    v

    in some cases.

    Considering the work-load with PT1prEN 1992-1-1 (2017), more parameters are

    included. However, they may not require that much eort to obtain.

    New perspectives on climate: Earth surface processes and thermal hydrological conditions in high latitude systems2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Climate, Earth surface processes and soil thermal hydrological conditions drive landscape development, ecosystem functioning and human activities in high latitude regions. These systems are at the focal point of concurrent global change studies as the ongoing shifts in climate regimes has already changed the dynamics of fragile and highly specialized environments across pan Arctic. This thesis aimed to 1) analyze and model extreme air temperatures, soil thermal and hydrological conditions, and the main Earth surface processes (ESP) (cryoturbation, solifluction, nivation and palsa mires) controlling the functioning of high latitude systems in current and future climate conditions; 2) identify the key environmental factors driving the spatial variation of the studied phenomena; and 3) develop methodology for producing novel high quality datasets. To accomplish these objectives, spatial analyses were conducted throughout geographical scales by utilizing multiple statistical modelling approaches, such as regression, machine learning techniques and ensemble forecasting. This thesis was based on unique datasets from the northern Fennoscandia; climate station records from Finland, Sweden and Norway, state of the art climate model simulations, fine scale field measurements collected in arctic alpine tundra and remotely sensed geospatial data. In paper I, accurate extreme air temperature maps were produced, which were notably improved after incorporating the influence of local factors such as topography and water bodies into the spatial models. In paper II, the results showed extreme variation in soil temperature and moisture over very short distances, while revealing the factors controlling the heterogeneity of ground thermal and hydrological conditions. Finally, the modelling outputs in papers III and IV provided new insights into the determination of geomorphic activity patterns across arctic alpine landscapes, while stressing the need for accurate climate data for predictive geomorphological distribution mapping. Importantly, Earth surface processes were found to be extremely climatic sensitivity, and drastic changes in geomorphic systems towards the end of 21st century can be expected. The increase of current temperature conditions by 2 ˚C was projected to cause a near complete loss of active ESPs in the high latitude study area. This thesis demonstrated the applicability of spatial modelling techniques as a useful framework in multiple key challenges of contemporary physical geography. Moreover, with the utilized model ensemble approach, the modelling uncertainty can be reduced while presenting the local trends in response variables more robustly. In future Earth system studies, it is essential to further assess the dynamics of arctic alpine landscapes under changing climatic conditions and identify potential tipping points of these sensitive systems.

    The meso-scale drivers of temperature extremes in high-latitude Fennoscandia2014In: Climate Dynamics, ISSN 0930-7575, E-ISSN 1432-0894, Vol. 42, no 1, p. 237-252Article in journal (Refereed)
    Abstract [en]

    Extreme temperatures are key drivers controlling both biotic and abiotic processes, and may be strongly modified by topography and land cover. We modelled mean and extreme temperatures in northern Fennoscandia by combining digital elevation and land cover data with climate observations from northern Finland, Norway and Sweden. Multivariate partitioning technique was utilized to investigate the relative importance of environmental variables for the variation of the three temperature parameters: mean annual absolute minima and maxima, and mean annual temperature. Generalized additive modeling showed good performance, explaining 84–95 % of the temperature variation. The inclusion of remotely sensed variables improved significantly the modelling of thermal extremes in this system. The water cover variables and topography were the most important drivers of minimum temperatures, whereas elevation was the most important factor controlling maximum temperatures. The spatial variability of mean temperatures was clearly driven by geographical location and the effects of topography. Partitioning technique gave novel insights into temperature-environment relationship at the meso-scale and thus proved to be useful tool for the study of the extreme temperatures in the high-latitude setting.

    Revealing topoclimatic heterogeneity using meteorological station data2017In: International Journal of Climatology, ISSN 0899-8418, E-ISSN 1097-0088, Vol. 37, no Suppl. 1, p. 544-556Article in journal (Refereed)
    Abstract [en]

    Climate is a crucial driver of the distributions and activity of multiple biotic and abiotic processes, and thus high-quality and high-resolution climate data are often prerequisite in various environmental research. However, contemporary gridded climate products suffer critical problems mainly related to sub-optimal pixel size and lack of local topography-driven temperature heterogeneity. Here, by integrating meteorological station data, high-quality terrain information and multivariate modelling, we aim to explicitly demonstrate this deficiency. Monthly average temperatures (1981-2010) from Finland, Sweden and Norway were modelled using generalized additive modelling under (1) a conventional (i.e. considering geographical location, elevation and water cover) and (2) a topoclimatic framework (i.e. also accounting for solar radiation and cold-air pooling). The performance of the topoclimatic model was significantly higher than the conventional approach for most months, with bootstrapped mean R-2 for the topoclimatic model varying from 0.88 (January) to 0.95 (October). The estimated effect of solar radiation was evident during summer, while cold air pooling was identified to improve local temperature estimates in winter. The topoclimatic modelling exposed a substantial temperature heterogeneity within coarser landscape units (>5 degrees C/1 km(-2) in summer) thus unveiling a wide range of potential microclimatic conditions neglected by the conventional approach. Moreover, the topoclimatic model predictions revealed a pronounced asymmetry in average temperature conditions, causing isotherms during summer to differ several hundreds of metres in altitude between the equator and pole facing slopes. In contrast, cold-air pooling in sheltered landscapes lowered the winter temperatures ca. 1.1 degrees C/100m towards the local minimum altitude. Noteworthy, the analysis implies that conventional models produce biassed predictions of long-term average temperature conditions, with errors likely to be high at sites associated with complex topography.

    The Nordic Swan - From past experiences to future possibilities: The third evaluation of the Nordic ecolabelling scheme2008Book (Other academic)
    Abstract [en]

    This report presents the third evaluation of the Nordic Swan ecolabelling scheme. The evaluation is conducted from the perspective of the public administration, and it examines the role of the Nordic Swan in a policy context. Recommendations are presented for authorities in the Nordic countries and for the bodies operating the schemes on a Nordic and national level. The evaluation focuses on current opportunities and challenges in the operating environment of the scheme. It examines the relations between the Nordic Swan and the EU Eco-label in the Nordic countries, including their governance procedures, popularity and reception in the market. Other current topics addressed include the progress achieved by the Nordic marketing strategy for the Swan and some current governance issues in the scheme, including the grounds for public funding for the Nordic Swan. The report also analyses the relations between the Swan and other environmental information systems. In particular, the report investigates the opportunities and challenges ensuing from the current attention to climate issues for the Nordic Swan.

    Nervrotsblockad i kombination med fysioterapi för patienter med diskbråck - en single subject experimental design2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Diskbråck i ländryggen med symtom av ischias, bensmärta, är en vanlig orsak till specifika ryggbesvär. Konservativa behandlingsmetoder rekommenderas före kirurgi. Diagnosen diskbråck är förknippad med kraftig smärta och begränsningar och är en vanlig orsak till att söka vård och behandling. Trots detta finns det idag ingen konsensus kring vilka behandlingsmetoder som är mest effektiva vid diskbråck.

    Syfte: Att undersöka effekten av nervrotsblockad i kombination med individanpassad fysioterapi på smärta och aktivitetsförmåga för patienter med symtomgivande lumbosakralt diskbråck.

    Metod: Studiens utformning var en Single Subject Experimental Design (SSED), med en A-B design. Under baslinjefasen, A och interventionsfasen, B utfördes systematiska och upprepade mätningar av smärtintensitet och aktivitetsförmåga över tid. Totalt fem patienter med lumbosakralt diskbråck rekryterades från en klinik. Studien omfattades av två interventioner. Två patienter behandlades med nervrotsblockad (NRB) i kombination med individanpassad fysioterapi och tre patienter behandlades endast med NRB. Mätdata presenteras med grafer i linjediagram och analyserades visuellt.

    Resultat: De två patienterna som fick NRB i kombination med individanpassad fysioterapi förbättrades avseende smärta respektive aktivitetsförmåga, under nio respektive fem veckors interventionsfas. Av de tre patienter som behandlades enbart med NRB upplevde en patient en försämring avseende smärta och aktivitetsförmåga, en valde att avsluta sin medverkan och en behandlades som bortfall.

    Slutsats: NRB i kombination med individanpassad fysioterapi kan minska smärta och förbättra aktivitetsförmåga för enskilda patienter med symtomgivande lumbosakralt diskbråck.

    Nordiska goda exempel på stöd till studenter med funktionsnedsättning under utbildningen och under övergången från utbildning till arbete.

    Artikel 24 i FN:s konvention om rättigheter för personer med funktionsnedsättning, som alla nordiska länder harundertecknat, betonar rätten till utbildning på lika villkor. Den nationella funktionshinderpolitiken i de nordiska länderna betonar betydelsen av att personer med funktionsnedsättning ska få stöd under utbildningsperioden och i samband med övergången från utbildning till arbete.

    Ett syfte med detta häfte är att ge inspiration och idéer till universitet och högskolor i Norden för att underlätta för studenter med funktionsnedsättning att delta i och genomföra en högre utbildning. Ett annat syfte är att uppmärksamma övergången från utbildning till arbete.

    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.

    Jómsvíkinga Saga as a Part of Old Norse Historiography2014In: Scripta Islandica: Isländska Sällskapets Årsbok, ISSN 0582-3234, E-ISSN 2001-9416, Vol. 65, p. 33-58Article in journal (Refereed)
    Abstract [en]

    The article argues that Jómsvíkinga saga, despite its mixed modality, should be included in Old Norse historiography. A comparison with kings’ sagas and legendary sagas — in this case Yngvars saga víðfǫrla — shows how these modes were used in Jómsvíkinga saga. The saga is often grouped with Orkneyinga saga and Færeyinga saga, which were also written around the year 1200; all deal in some way with the relationship between kings and aristocrats. The reason for this may be found in contemporary events: The Scandinavian kings were strengthening their position, while the aristocracy was trying to maintain its influence. Therefore, the sagas have also been called political sagas. The oldest extant versions of Jómsvíkinga saga contain the first part of the saga, which deals with the history of the Danish Kings; this shows that the saga was intended to be perceived as history. However, a later version (AM 510 4to) omits this part, which suggests that the historicity of the saga had eroded. The fact that Jómsvíkinga saga was incorporated into manuscripts containing legendary sagas also shows that the saga may have been valued for its entertaining plot and not because of its connections to real events and historical characters.

    The Sami Representations Reflecting the Multi-Ethnic North of the Saga Literature2017In: Journal of Northern Studies, ISSN 1654-5915, Vol. 11, no 2, p. 7-30Article in journal (Refereed)
    Abstract [en]

    This article focuses on contextualizing the Sami (finnar) representations in Old Norse saga literature. The purpose is to show that the Sami representations reflect multi-layered Old Norse textual and oral traditions, and complex interaction between the Sami and the Norwegians in the Middle Ages. The stereotypes of the Sami tell us more about the society that created them than about real, historical events. We can be sure that behind them lie very mundane phenomena such as trade and marriages.

    The ultimate goal of the article is therefore to reveal the multi-ethnic North that provided the background for the saga sources, a North whose history is not as homogeneous as sources suggest and quite unlike the modified version which found its way into the histories of nation states. The literary conventions of sagas are not just imaginary tales—their use in various contexts can reveal something essential in otherwise schematic images or configurations. Even researchers of the sagas have certain personal conceptions of what the “real” lives of the Sami were like at the time, and how the sagas depict this. In fact, they participate in a continuum of saga literature that generates representations of the Sami in history.

    Les influences françaises dans la Russie tsariste: sur les réformes culturelles, sociales et politiques2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [fr]

    Le mémoire traite de l’influence des idées françaises des Lumières sur la Russie et son évolution, notamment sociale, politique et culturelle. Cette étude est concentrée sur les deux tsars les plus célèbres et leur règne respectifs, Pierre Ier le Grand et Catherine II la Grande puisqu’ils ont été à l’origine de la plupart des réformes. Une description de la Russie avant l'époque de Pierre Ier et du siècle des Lumières, ses philosophes et ses idées fondamentales, est aussi présentée. Le mémoire se termine par une brève discussion sur les réformes essentielles faites dans la Russie tsariste.

    Behöver pensionssystemet en förändring?: En studie om investmentbolag i premiepensionssystemet2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this study is evaluate if there is another investment opportunity than the current investment opportunities in the Swedish pension system. In order to do this the study will produce a portfolio of a Swedishand an international investment company with a good balance between risk and return for a comparison of today’s premium pension scheme.

    Methodology: The study is based on historical data for ten years which further is analyzed through the Pearson R model. The selection consists of investment companies in the Nordic- and the American market. Along with the quantitative study an interview will be made with a representative well familiar with savings and pension investments. Finally the credibility of the study and methodology criticism is presented.

    Theoretical Framework: The theoretical frame of reference consists of previous theories that are relevant to produce the best-suited portfolio. Markowitz modern portfolio theory is the main theory which is supplemented by additional essential measures as the Sharpe ratio. Furthermore, a developed portfolio theory by Grubel & Solnik is applied to get an international perspective.

    Result: The result consists of a presentation of the processed data as underlies the analysis being carried out.

    Conclusions: The study produces a portfolio in the form of Bure Equity AB and Berkshire Hathaway. In comparison with the pre-existing pension options the study’s portfolio shows a significantly higher nominal return. The constellation of Bure Equity AB and Berkshire Hathaway exhibits a nominal return of 19,75 % in relation to the active saver in the premium pension with a nominal return of 7 %. The passive saver assigned to AP7 Safa exhibits a nominal return of 11 %.

    Ground Monitoring using Resistivity Measurements in Glaciated Terrains2001Doctoral thesis, comprehensive summary (Other scientific)
    Abstract [en]

    The most common method of monitoring and mapping groundwatercontaminants is to extract and analyse a number of groundwatersamples from wells in the investigation area. However, thereare a number of limitations with this type of point-wiseinvestigation, as it is hard to acquire an adequate picture ofa heterogeneous and anisotropic subsurface using a fewpoints.

    To overcome the limitations of point investigations and toimprove ground monitoring investigations in a cost-effectiveway, support can be provided by direct current resistivitymeasurements, which give a characterisation of the electricalproperties of a ground volume.

    The main objective with this work was to investigate theusability of the resistivity method as a support in monitoringgroundwater contaminants in glaciated terrains and underdifferent seasons, both in long-term monitoring programmes andintracer tests.

    The work comprised field investigations at several differentsanitary landfills and four tracer tests in differentgeological environments, around the Stockholm region. The maininvestigations have been done at Högbytorp, Stockholmwhich has been used for long-term investigations of theresistivity variation, together with a field set up formonitoring and measurements on seasonal variation in soilmoisture, ground temperature and precipitation.

    It can be concluded that the use of resistivity measurementssupplies valuable information in the case of mapping andmonitoring conductive groundwater contaminants andfurthermore:

    The variation in resistivity (in shallow investigations<1 m) can be extensive between different seasons (around30 % compared to a mean value in till and clay soils) andshould be considered, so that anthropogenic affects can beseparated from natural resistivity variation. For deeperinvestigations (>5 m) the seasonal resistivity variationwas more moderate (around 15% compared to a mean value intill and clay soils).

    Soil moisture variation shows a strong relationship toresistivity variation in the investigated clay and tillsoils. Together with temperature correction 47 to 65% of thevariation has been explained.

    Three types of monitoring systems can be applied:Permanently installed, partly installed and fully mobilesystems. For the actual measurements, all three types can useeither high-density techniques such as CVES (ContinuousVertical Electrical Sounding) or low-density measuring withone or some different electrode spacings.

    The suggested evaluation tool for monitoring programmesshowed that it was possible to detect a decrease of 15 % inthe mean value at a specific site using Modified Double Masscalculations between resistivity time series and time seriesat a reference site with a comparable seasonalvariation.

    Resistivity measurements may be used as a valuablecomplement to groundwater sampling in tracer tests. Adecrease in resistivity, a minimum and a recovery phasereflect the passage of a NaCl-solution, which can be used toestimate flow velocity and flow patterns of the investigatedaquifer. The achieved recovery of NaCl in the tracer testscarried out was estimated to 20 to 70 %.

    The measurement system for long-term monitoring or tracertests, which should be chosen with regard to layout andfrequency, depends on the purpose of measurement and onsite-specific conditions and therefore no standard solutioncan be proposed.

    Key words:Resistivity, Direct Current, Monitoring,Groundwater, Contaminant, Tracer test, Geophysics.
