    Brandteknisk dimensionering av limträkonstruktion: En ekonomisk jämförelse mellan överdimensionering och brandskydd av en limträkonstruktion, för att uppnå gällande brandkrav på bärförmåga.2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study aims to determine whether it’s most efficient, in terms of cost, to over dimension a glulam construction or to fire protect it, given the current fire requirements. The intention is to simplify the choice of fire protection methods used on larger buildings, since there could be tremendous costs, depending on the methods used. The delimitations applied in this study are to neither dimension nodes nor take these into account. The labor cost for building the glulam construction was not included in the study.

     

    The survey was divided into two cases, where the first one was to over dimension the glulam construction, in order meet the fire resistance class in the SS-EN standard, up to level R240. The other case was to fire protect the glulam construction, meeting the same fire resistance class as in the first case. Furthermore the expense for materials and labor for the different cases where compared to each other. This provided a clear picture of which one of the two cases that where most efficient in terms of costs.

     

    The result shows that in terms of cost, the most efficient way to fire protect the glulam construction is to over dimension it. There are few products on the market that can meet high fire standards over R90, and the dimensions in the ultimate limit state is already reaching the standard R90, in the design fire load density.

    Dimensionering av en friidrottshall: En ekonomisk jämförelse mellan två olika lastbredder2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this work, two different load widths are compared to see which load width is the cheapest. These load widths are based on an assumed standard dimension and an optimization of the carrier plate used in the work. The chosen design solutions are checked in both the crash and the user limits and the dimensioning of a single reduced cross section for fire according to applicable laws and regulations. The fire dimensioning is to a large extent the dimensional load for load-bearing parts. The dimensioning relates only to wooden structures and tension rods in steel. Plates and couplings are not dimensioned but are discussed in the discussion. The work does not only deal with the dimensions of the construction in the sports stadium without an outline draft proposal also following a local program and a building plan over the available area. The sketch proposal is developed through IAAF:s standards for indoor facilities and miscellaneous plans for Swedish athletics facilities. The facility is constructed in wood and with drawstring in steel for the brace of wind. The roof construction consists of a support plate and a fish abdominal truss with a span of 61 meters. Roof structures rest on wooden columns, which for the last foundation, the dimensions of the building are 61x125x15 meters large. The shorter load will be cheaper and would probably be even cheaper if the costs of the plate and the clutches were included in the result. The idea for this work came from a coincidence when the athletics facility in Östersund is classified as unfit for the sake of mold and an athlete trainer who works with the municipality has started a non-profit project. The project intends to build a new, larger athletics facility within the Östersund arena area.

    Jämförelse av limträ i gran och bok: En jämförelse av två limträprodukter mot varandra ur ett konstruktions- och kostnadsperspektiv2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    When constructing constructions today, one wants to achieve large free surfaces, in wich case mostly columns and beamsystems are used. This study presents a construction built in Östersund, Sweden with two different wood materials. One of the constructions was built in Swedish glulam with strength class GL30c and the second construction was built in the German material BauBuche with strength class GL70.

    The study will present a cost and construction comparison between the two different wood materials. The constructions are adapted to the length restrictions for BauBuche, 18 meters span widths are the maximum for roof constructions and beams.

    The result of the study shows that BauBuche is economically more profitable to build with than Swedish glulam, the difference is a saving in material cost of 21.5 %. The study also shows a difference in capacity, where BauBuche has about 57.2 % higher torque capacity and about 41.4 % higher transverse capacity.

    By choosing BauBuche before glulam or combining these, one could get an optimal construction in wood where BauBuche stands for the parts that are exposed to the highest load.

    Det etiska och juridiska dilemmat: En rättssociologisk dokumentstudie om den gravida  missbrukande kvinnan och det ofödda barnet2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna rättssociologiska dokumentstudie är att analysera rättstillämpningen av LVM för missbrukande gravida kvinnor. Studiens empiriska material består av 16 förvaltningsrättsliga LVM-domar under tidsperioden 2010-2019 och utgår från ett intersektionellt perspektiv med stöd av paternalism. Vi kunde genom att studera domarna se återkommande mönster hur graviditeten och det ofödda barnet benämns, utifrån detta utarbetades tre teman som ligger till grund för vårt analysarbete; 1) könsroller och motivering till förändring, 2) hälsa och social utsatthet samt 3) risk att det ofödda barnet skadas. Studiens resultat visar bland annat att rättstillämpningen kopplar kvinnans missbruk till psykisk ohälsa samt att normer kring hur en kvinna bör och förväntas vara har en påverkan hur kvinnliga missbrukare framställs. Vidare visar studien att det ofödda barnet riskerar att skadas av kvinnans missbruk, men utifrån aktuell lagstiftning går det inte att ta hänsyn till det ofödda barnet som saknar juridiska rättigheter och inte ingår i närståendebegreppet i LVM. Utifrån detta uppstår ett etiskt och juridiskt dilemma mellan den gravida missbrukande kvinnans rättigheter och det ofödda barnets rätt till hälsa och utveckling vid en eventuell utökning av LVM.

    Principmodell för påbyggnad av tak till läktare: En jämförelse mellan limträ och stål i konstruktionen2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Jämtkraft arena is a football- and event arena in Östersund which was inaugurated in July 2007. The arena consists of four stands, of which the west and east are larger and have roofs over, while the other two, the north and south stands are easier in its design and lack roofs. The purpose of this thesis is to design a roof as an extension to the northern stand. The aim is that the roof should be attractive in its design, not obscure the view towards the field for the spectators, design the ceiling and walls to contribute to good acoustics and be economically and environmentally sustainable. Steel and glulam have been compared as framework material for the construction through a price comparison and which of the materials are preferable from an environmental point of view with respect to carbon dioxide emissions.

     

    Based on existing drawings of the arena, wishes from Östersund FK's supporter club and recommendations from acoustics, a sketch proposal has been developed for the roof which was then drawn up in Tekla Structure. Statcon Structure has been used for dimensioning and a literature study has been carried out to study the subject, compare the various materials and study the design and materials of other roof constructions for arenas.

    The study shows that both wood and steel are a good material choice when constructing a roof structure for the platform. The result of the material comparison, however, shows that glulam is preferable from the chosen parameters. The frame of glulam give a cheaper construction and emits less carbon dioxide during manufacturing.

    Framtidens teknik för arkitekter: En studie om hur VR kan integreras på arkitektkontoret2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In a construction project, many people with different levels of experienceand areas of expertise are involved. In order to maximize efficiency inprojects, mutual trust between parties and clear communication is crucial.Several research projects have shown that VR (Virtual Reality)contributes to a better and more common understanding of plannedbuildings. Using a VR headset, the viewer can move around in a buildingand experience it in 1:1 scale.The aim of this study was to investigate how VR can be implemented atan architectural office by examining whether there are any gains with theimplementation, how VR can be used at different stages, how a 3D-modelshould be designed and how a VR-simulation is carried out in the bestway. This study has been limited to using the VR system HTC Vivetogether with the BIM-software Revit and the visualization plug-inEnscape.A literature study has been conducted to map the theory around thesubject. Tests have been conducted where an architect, a design manager,users, clients and contractors have been able to carry out VR-simulations.The 3D-model that has been used for the simulations, has been adaptedwith rooms in three different detail levels. After the simulations, the testsubjects have been interviewed about the experience and their thoughts onimplementing the technology.The result of this study suggests that VR contributes to an increasedspatial understanding and gives a better understanding of the final result.According to the study, VR can be used in several different stages of theproject, both internally at the architectural office and as a communicationtool for users, clients and other consultants.The study has resulted in proposed guidelines for how a 3D-model shouldbe designed and how a VR simulation can be done.

    Undersökning av lämpliga rekommendationer att åta för minskad klimatpåverkan från byggbranschen: Hur kan projekteringen minska klimatpåverkan?2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this assignment has been to come up with recommendations ofwhich can be used in early project planning stages. The goal has been to makerecommendations who make future buildings perform better climate values. Therecommendations can be used to achieve the goals described in theGovernment's prepared roadmap for a fossil-free construction and civilengineering industry. Delimitations to the organization's four main measureshave been taken and the measures apply only to new construction of buildings.The delimitations also describe that the measures can be referred to the earlyproject planning stage. Governmenten's roadmap does not describe how theorganization need to work to establish better climate values of a building. It istherefore up to each organization to put up a plan for how to work to achieve thegoals described in the roadmap. This assignment shows that the most importantrecommendations to make is the choice of load-bearing frame system andbuilding materials, streamline and plan the transport, project and plan for flexiblebuildings and demolition, as well as project and plan for a sustainable building.These recommendations have been developed through telephone interviews withpeople who has been involved in projects that can be seen as reference projects.An order for the construction and construction industry to achieve fossil-freecompetitiveness, however, it requires common goals that can be worked out ifregulatory requirements change. A clear definition of what a building with goodclimate values is, is also necessary for all actors in the industry to be able tostamp the same goals and vision.

    Djur som en del av vården på särskilda boenden för äldre: - En kvalitativ studie om enhetschefers erfarenheter och upplevelser av djurs inverkan på boende- och arbetssituationen på särskilda boenden för äldre2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Arbetssituationen på särskilt boende för äldre är ansträngd med begränsade resurser och ökat krav på effektivitet. För att få en arbetsgrupp att känna sig tillfreds med sin arbetssituation krävs ett gott ledarskap och en fungerande arbetssituation. Det finns forskning som visar på att djur har positiv inverkan på de äldre som bor på särskilt boende men forskningen är bristfällig på hur djur påverkar andra delar av verksamheten. Den här studien har undersökt vilka erfareneheter och upplevelser enhetschefer har av att använda djur på särskilt boende för äldre. Användandet av djur har undersökts utifrån ledarskap och hur enhetscheferna tänker kring djurens påverkan på personalen och de boende. Resultatet har analyserats och jämförts med tidigare forskning inom området samt de teoretiska perspektiven socialkonstruktivism, systemisk konstruktionism och teorier om ledarskap. Resultatet i studien har visat att det är positivt för enhetschefer att inkludera djur på särskilda boenden för äldre. Slutsatsen av denna studie är att djur har en positiv inverkan på hela verksamheten med rätt ledarskap. Enhetschefer på särskilda boenden borde lägga mer tid på att använda djur för att förbättra boende- och arbetssituationen. Antingen genom att använda sig av djur som varaktigt vistas på boendena eller åtminstone mer kontinuerligt ha besök av djur.

    Evaluating the performance of a vibration energy harvester under complex excitation2020Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In recent years, vibration energy harvesting has become a research hotspot in the field of energy harvesting. Energy harvester output power is the most important parameter in a vibration energy harvesting system. Assessing the harvester output power in different vibration environments is an important study issue to study. This thesis proposed a research method for harvester output based on the complex vibration environment simulated in the laboratory, a closed-loop control experimental system for the simulated vibration environment was established, the system can simulate a vibration environment with specific vibration frequency and acceleration, and automatically measure the harvester output power. Using FFT methods to analyse the harvester output voltage waveform, research the relationship between the harvester output power and the noise vibration signal frequency. Polynomial fitting modelling method is used for the harvester output power prediction in the 62.5Hz dominant frequency vibration environment. At the same time, researching the harvester output power in different dominant frequency and same vibration acceleration vibration environment which containing noise signal. Through the analysis of harvester output power, it was found that, for the case of the vibration environment dominant frequency is 62.5Hz, all noise frequency component of the vibration signal will reduce the output power of vibration energy harvester modelD, especially when the noise frequency is around 57.5Hz and67.5Hz, the output power of vibration energy harvester modelD is quite lower than the output power of harvester under the pure sinusoidal excitation signals. For the case of the vibration environment dominant frequency is not 62.5Hz, if the noise frequency component of the vibration signal close the harvester resonance frequency, it has a great impact on output power, and the output power of harvester is higher than the output power of harvester under the pure sinusoidal excitation signals. The presented research methods apply to most such studies, which can help user to analyse the effect of vibration noise on the harvester output and helps increase the harvester's output power. Research conclusions can provide user a reference in harvester selection.

    High strength paper from high yield pulps by means of hot-pressing2020Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Abstract

    High Yield Pulp (HYP), i.e. TMP, SGW or CTMP, is normally used in printing papers (News, SC and LWC) or in a middle layer on cardboard i.e. in products that either have high demands on printability and runnability in fast printing presses or contribute to high bulk in cardboards in order to minimize pulp consumption at a certain sheet stiffness. Tensile strength as a function of density is significantly higher for HYP compared to chemical pulps such as sulphate and sulphite pulps. However, chemical pulp is mainly used in packaging materials that require very high tensile strength, while at the same time allowing the density of the paper to be high. By utilizing the softening properties of high-yielding lignin-rich fibres by hot-pressing technology, it is possible to significantly increase sheet density and thereby strength closer to the level of chemical pulps. Furthermore, due to the presence of high levels of lignin, it was shown that considerably higher wet strength can be achieved compared to chemical pulp without the addition of strengthening agents. The study focuses on the softening of stiff and lignin-rich fibres in papers based on HYP with sufficiently high moisture contents, when hot-pressing at temperature levels significantly above the softening temperature (Tg) of lignin Hot-pressing increases the density of the sheet which increases the contact surface between the fibres in the paper structure. The high pressing temperature can be said to induce a viscous flow of lignin, which also increases the potential for fibre-fibre bonding. It is conceivable that covalent bonds are obtained via condensation reactions and partly that interdiffusion between the lignin in the fibre walls can be obtained as they come close enough to each other during the hot-pressing. The research also shows that hot-pressing greatly improves properties in the form of dry and wet strength as well as hydrophobicity for HYP and for lignin-rich kraft paper. The first part of the study shows the effect of hot-pressing on strength properties of paper sheets based on CTMP, HT-CTMP, TMP, NSSC, SCPal and NBSK. The second part includes a study on how and to what extent different amounts of residual lignin in the pulp contribute to the dry and wet strength of the sheets of paper during hot-pressing as a function of increasing temperature. To demonstrate this, pilot scale cooking of unbleached pulp to various lignin levels was carried out. In all experiments in parts one and two, laboratory sheets with a surface weight of 150 g/m2 and a dry content of 50% were made with a Rapid Köthen (RK) sheet former, after which the sheets were hot-pressed in a cylinder press at temperatures up to 200°C, constant high pressure of about 7 MPa, nip pressure dwell time of 1.5 sec and production speed 1 m/min. The third part includes a study on the optimization of variables in a new design of a dynamic cylinder press for hot-pressing technology. This design is based on previous research at Mid Sweden University combined with key knowledge of steel band technology within IPCO AB. The new pilot machine is based on heating of a steel belt with infrared heat (IR) up to 300°C, a maximum line load of 15 kN/m in two press nips and a dwell time of 23-240 ms in the nip depending on the production speed which is up to 5 m/min. The experiments in part three were based on RK paper sheets with 100 g/m2 and approximately 63% dry content made by HT-CTMP. The results confirm that hot-pressed HYP-based paper sheets enable permanent densification by softening lignin, which provides a very high dry tensile strength and a remarkable improvement in wet tensile strength compared to bleached kraft pulp without the need for wet strength agents. A tensile index of 75 kNm/kg, compression strength index (SCT) of 45 kNm/kg and wet tensile strength index of 16 kNm/kg were obtained, which can be compared with the corresponding values for bleached kraft pulp based paper sheets of 85 kNm/kg, 35 kNm/kg and 5 kNm/kg respectively, all with the same density after hot-pressing at 200°C. The NSSC reached the highest tensile strength index of 92 kNm/kg. The study with the unbleached kraft pulps showed that the lignin content had a significant effect on both the dry and wet tensile strength indices. The pulps showed a linear relationship between wet strength and lignin content. The increase in lignin content from 0% to 12% improved the dry tensile index by 20% and SCT by 35% and gave a very significant increase in the wet strength index from 3 to 23 kNm/kg after hot-pressing. All lignin-rich paper samples exhibit good wet stability for at least 24 hours and an improved surface hydrophobicity by increasing the pressing temperature and lignin content.

    Optimization of the new steel belt based press machine showed that high nip pressure and two press nips had a great effect on density and strength. Whereas high temperature, well above Tg of lignin, and long pressing time were more important to achieve high wet strength. The highest wet strength index value, 27 kNm/kg, was reached when the pressing temperature was 290°C, the nip pressure about 8 MPa, the pressing time in the press nip 40 ms and the dwell time in contact with the steel belt 23.5 sec. It was also noted that no delamination occurred in these tests.

    In order to obtain both high dry and wet strength, it is important to have high lignin content, high temperature, high nip pressure and sufficiently long pressing time

    Synthesis of a NiMoO4/3D-rGO nanocomposite via starch medium precipitation method for supercapacitor performance2020In: Batteries, ISSN 2313-0105, Vol. 6, no 1, article id 5Article in journal (Refereed)
    Abstract [en]

    This paper presents research on the synergistic effects of nickel molybdate and reduced graphene oxide as a nanocomposite for further development of energy storage systems. An enhancement in the electrochemical performance of supercapacitor electrodes occurs by synthesizing highly porous structures and achieving more surface area. In this work, a chemical precipitation technique was used to synthesize the NiMoO4/3D-rGO nanocomposite in a starch media. Starch was used to develop the porosities of the nanostructure. A temperature of 350◦C was applied to transform graphene oxide sheets to reduced graphene oxide and remove the starch to obtain the NiMoO4/3D-rGO nanocomposite with porous structure. The X-ray diffraction pattern of the NiMoO4 nano particles indicated a monoclinic structure. Also, the scanning electron microscope observation showed that the NiMoO4 NPs were dispersed across the rGO sheets. The electrochemical results of the NiMoO4/3D-rGO electrode revealed that the incorporation of rGO sheets with NiMoO4 NPs increased the capacity of the nanocomposite. Therefore, a significant increase in the specific capacity of the electrode was observed with the NiMoO4/3D-rGO nanocomposite (450 Cg−1 or 900 Fg−1) when compared with bare NiMoO4 nanoparticles (350 Cg−1 or 700 Fg−1) at the current density of 1 A g−1. Our findings show that the incorporation of rGO and NiMoO4 NP redox reactions with a porous structure can benefit the future development of supercapacitors.

    Identification of (Z)-8-Heptadecene and n-Pentadecane as Electrophysiologically Active Compounds in Ophrys insectifera and Its Argogorytes Pollinator2020In: International Journal of Molecular Sciences, ISSN 1422-0067, E-ISSN 1422-0067, Vol. 21, no 2Article in journal (Refereed)
    Abstract [en]

    Sexually deceptive orchids typically depend on specific insect species for pollination, which are lured by sex pheromone mimicry. European Ophrys orchids often exploit specific species of wasps or bees with carboxylic acid derivatives. Here, we identify the specific semiochemicals present in O. insectifera, and in females of one of its pollinator species, Argogorytes fargeii. Headspace volatile samples and solvent extracts were analysed by GC-MS and semiochemicals were structurally elucidated by microderivatisation experiments and synthesis. (Z)-8-Heptadecene and n-pentadecane were confirmed as present in both O. insectifera and A. fargeii female extracts, with both compounds being found to be electrophysiologically active to pollinators. The identified semiochemicals were compared with previously identified Ophrys pollinator attractants, such as (Z)-9 and (Z)-12-C27-C29 alkenes in O. sphegodes and (Z)-9-octadecenal, octadecanal, ethyl linoleate and ethyl oleate in O. speculum, to provide further insights into the biosynthesis of semiochemicals in this genus. We propose that all these currently identified Ophrys semiochemicals can be formed biosynthetically from the same activated carboxylic acid precursors, after a sequence of elongation and decarbonylation reactions in O. sphegodes and O. speculum, while in O. insectifera, possibly by decarbonylation without preceding elongation.

    Som en oinbjuden gäst som aldrig går hem: En litteraturöversikt om hur personer upplever sin vardag med kronisk smärta2020Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Det fanns en stark koppling med långvarig kronisk smärta samt försämrad livskvalitet. Livet med kronisk smärta skapade olika begränsningar för personen. Sucidrisken är ökad för dessa personer jämförelsevis med den generella befolkningen. Smärtan kan vara svår att mäta med kliniska markörer och det fanns olika typer av smärtbehandlingar. Smärtan kan komma i olika former av livslidande som beskrevs som en teori.

    Syfte: Beskriva personers upplevelser av att leva med kronisk smärta i vardagen.

    Metod: Litteraturöversikten var av kvalitativ design med en deskriptiv ansats där 11 vetenskapliga artiklar har efter urval baserat på inklusions- och exklusionskriterier gått vidare till kvalitetsgranskning samt analys.

    Resultat: Tre kategorier framkom. ”Emotionella upplevelser”, ”Begränsningar” samt ”Hantera den kroniska smärtan”. Personer som inte blev trodda på och inte sedda upplevde ett lidande. Personer upplevde olika typer av begränsningar i vardagen relaterade till sin kroniska smärta. Familjen var främsta stödet för personen i deras hantering av den kroniska smärtan. Olika typer av behandlingar hade också betydelse i deras upplevelse av att hantera smärtan.

    Diskussion: Omvårdnaden spelade stor roll i lindringen av den kronisk smärtan som också visar sig i olika former av lidande. Personer kan uppleva smärtlindring olika och det sätter ett krav att bra kommunikation ska tillhöra omvårdnaden. Närstående är ett stort stöd för dessa personer och borde inkluderas i omvårdnaden.

    Slutsats: Det fanns fördelar för personer med kronisk smärta att omvårdnaden tog hänsyn till deras upplevelser. Vidare behövdes mer forskning för att utveckla flera metoder att mäta smärtan mer effektivt och förebygga de ökade riskerna.

    Se mig för den jag är, där jag är: En litteraturstudie om HIV-drabbade patienter2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: HIV är en immunsupprimerande sjukdom som kan drabba människor världen över. Sjukdomen är starkt förknippad med fördomar och diskriminering. HIV-drabbade individer är i behov av vård resten av livet. Det är därför viktigt att belysa deras upplevelse av bemötande och dess betydelse inom hälso- och sjukvården.

    Syfte: Syftet var att beskriva HIV/AIDS drabbade individers upplevelse av bemötandet och dess betydelse inom hälso- och sjukvården.

    Metod: En litteraturöversikt med induktiv design. De 18 artiklar som har används i resultatet är utifrån kvalitativ, kvantitativ och mixad metod.

    Resultat: Analysen resulterade i fem kategorier; ensidig kommunikation och bristfällig information, försummad sekretess, stigmatiserande beteenden, betydande faktorer för god vård och sambandet mellan tillfredställande vård och följsamhet. Resultatet visade på att hälso- och sjukvårdspersonalens förhållningssätt till HIV/AIDS hade en stor betydelse i hur bemötandet upplevdes samt en inverkan på den fortsatta vården.

    Diskussion: Då individerna inte bemöttes utifrån personcentrerad omvårdnad inom den allmänna vården blev kontrollförlust, ångest och dålig självkänsla en central del i deras upplevelse av hälso- och sjukvården. I jämförelse med kliniker med inriktning på HIV/AIDS beskrevs hälso- och sjukvårdspersonalen som kompetenta, icke-dömande och inbjudande. Slutsats: Hälso- och sjukvårdspersonalen bör arbeta utifrån personcentrerad omvårdnad för att skapa de bästa förutsättningarna för HIV-drabbade. Bemötandet har en stor betydelse för HIV- drabbades vård.

    “Making do” in rural tourism: the resourcing behaviour of tourism micro-firms2020In: Journal of Sustainable Tourism, ISSN 0966-9582, E-ISSN 1747-7646Article in journal (Refereed)
    Abstract [en]

    We propose entrepreneurial bricolage as a framework that enables the description, explanation and exploration of the modus operandi of tour- ism micro-firms. Particularly, the notion of spatial bricolage constitutes fertile ground for further research and theoretical advances of sustain- able tourism entrepreneurship. The potential for rural tourism develop- ment is conditioned by entrepreneurs’ capability to utilise local physical and non-material resources sustainably. Thus, knowledge about the resourcing behaviour of micro-firms is paramount to understanding their role in promoting sustainable tourism. This study explores how rural micro-firms interact with their spatial environment to design tour- ism value propositions. Our analysis is based on interviews with eight- een owners-managers of tourism micro-firms in rural Sweden. We portray spatial bricolage as a resourcing behaviour that builds on the re-interpretation of existing resources, the unique features of the destin- ation and community involvement. The findings suggest that resource transfer facilitates sustainable development since it enables long-term planning and validates the entrepreneurs’ operation. Moreover, their small-scale enables rural tourism firms to utilise local resources in non- exploitative ways that minimise disturbance for other stakeholders.

    Skönlitterära rum: Hur barn upplever sina läsmiljöer2020Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta är en kvalitativ intervjustudie där elevers uppfattningar av sina skönlitterära läsmiljöer undersöks. Denna studie syftar till att öka kunskapen om vilka olika synsätt elever har på de skönlitterära läsmiljöer de erbjuds, både i skolan och hemmet. Jag vill med denna studie bidra med ett elevperspektiv på läsmiljöer, där barns egna tankar, upplevelser och uppfattningar ges utrymme inom ett forskningsfält som annars till största del präglas av ett vuxenperspektiv. Undersökningen har utförts genom semistrukturerade elevintervjuer med sju stycken fjärdeklassare. Därefter har materialet transkriberats och tolkats mot bakgrund av ett antal teorier och inriktningar som på olika sätt belyst och möjliggjort ett fokus på kontexten inom vilken läsning sker. Tidigare forskning visar att den estetiska och fysiska läsmiljön har betydelse för barns motivation, engagemang och intresse för läsning. Därutöver utgör goda läsmiljöer en avgörande faktor för barns läsglädje. Vidare visar forskning att vi genom utformning och konstruering av läsmiljöer signalerar till elever vilka aktiviteter de förväntas ägna sig åt när de vistas i läsmiljön. Miljön inom vilken läsning äger rum har dessutom betydelse för barns möjlighet att leva sig in i fiktionens värld. Resultatet av studien visar att eleverna ser läsmiljön som en central och avgörande del för sin läsning. Vidare pekar eleverna ut faktorer för en god läsmiljö, så som koncentration, bekvämlighet, tilldragande atmosfär, utbud av och tillgång till skönlitteratur och specifika platser avsedda för läsning. Därutöver visar resultatet på den syn på läsning som skolan förmedlar till eleverna samt hur denna påverkar dem och deras egna syn på läsning.

    Vilken roll spelar genus när elever väljer barnlitteratur?: - En studie av grundskolans yngre år2020Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studien är att utifrån en kvalitativ metod ta reda på om pojkar och flickor gör olika bokval i skolan. I den kvalitativa studien utförs totalt två intervjuer, med en lärare och en skolbibliotekarie. I den kvalitativa studien genomförs även två observationer, den ena i ett klassrum och den andra i ett skolbibliotek. Den teoretiska utgångspunkten för arbetet har varit Lena Gemzöes genusteori utifrån feminismens grundtankar. Genusteorin genomsy-ras i hela studien som en röd tråd. Resultatet av studien visar att läraren och skolbiblioteka-rien arbetar med elevernas bokval på varsina håll och i olika utsträckning. Skolbibliotekarien är mer närvarande i elevernas bokval. Det synliggörs även att skolbibliotekarien har en större kännedom kring elevernas bokval. Läraren blir alltmer medveten kring elevernas val av böcker under intervjuns gång. Studien tar således upp möjliga faktorer som kan ligga till grund för elevernas genusbundna bokval med genusvetenskaplig bakgrund för arbetet.

    Den skönlitterära högläsningen i mellanstadiet: En aktuell undervisningsmetod2020Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att undersöka hur den skönlitterära högläsningen praktiserasi mellanstadiet enligt verksamma lärare. Studien arbetar efter frågeställningarna: “ Vad ärlärares inställning till den skönlitterära högläsningen?” , “ Vilka texter och verk föredrar lärareom de högläser för sina elever och varför ? ” samt “ Hur uppfattas möjligheterna att användadigitala verktyg vid högläsning av lärare? ” För att besvara frågorna utfördessemistrukturerade intervjuer med fyra verksamma lärare. Det är en kvalitativ studieinspirerad av hermeneutiken. Datan insamlat från de intervjuade lärarna analyseras i endiskussionsdel. Resultatet visade att alla intervjuade lärare praktiserar högläsning i sinaklassrum. Men att det skiljer sig mellan de intervjuade lärarna hur det praktiseras. Ävenvad lärarna definierade som högläsning. De intervjuade lärarna anser enhälligt atthögläsning ger ett bättre ordförråd och språkförståelse. En viktig faktor vid val av bokvar enhälligt. Den valda högläsningsboken måste fånga elevernas intresse. Val avhögläsningsbok grundades alltid på lärarens kännedom om sin klass. Digitala verktygpraktiseras olika av respondenterna och en varierande inställning till dem förekommer.Från starkt avståndstagande till full tillämpning av verktygen.

    Högläsning av skönlitteratur i grundsärskolan: En kvalitativ studie av tre lärares perspektiv på högläsning för elever med intellektuell funktionsnedsättning2020Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studie syftar till att undersöka lärares uppfattningar om barnlitteratu-rens roll i grundsärskolans verksamhet samt deras val av barnlitteratur. Tre lä-rare som är yrkesverksamma i grundsärskolan samt med inriktning tränings-skola, som är ett ämnesområde inom grundsärskolan, intervjuades från tre olika grundsärskolor, för att få en inblick i vad de ansåg om barnlitteraturen i verksamheten och dess funktion. Lärarna beskrev hur de valde böckerna, hur en lässtund ser ut, hur de upplevde att eleverna valde böcker, hur de arbetade med den lästa litteraturen samt vad de ansåg att barnlitteratur och högläsning fyller för funktion i verksamheten. I resultatdelen visas att lärarna anser littera-turen som en viktig del i verksamheten för elevernas språkutveckling, verklig-hetsuppfattning och samhörighet. Samtliga lärare sade att eleverna gärna väl-jer samma bok att läsa som t.ex. en elev som alltid valde ”Bockarna Bruse” men under intervjuerna fann jag att de tycktes ha olika förklaringar på varför detta skedde. Alla tre lärare tryckte på att det är högst individuellt i grund-särskolans verksamhet kring hur eleverna är mottaglig för vilka typer av böcker och att en stor utmaning är att kunna individanpassa. Under alla inter-vjuer särskilde samtliga lärare på den schemalagda högläsningen samt den spontana högläsningen.

    Styrsystem till avloppspumpstation: Vägledning vid val av automationsteknik2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this report the currently leading technologies for automation of sewage pump stations will be evaluated and compared. Based on this comparison a recommendation of a design will be done and the chosen control system will finally be assembled in a cabinet. The report shows that even thou there are energy savings to be done by using variable frequency drives it is rarely possible unless pumps are changed at the same time. When pumps are changed at the same time you have the opportunity to pick a pump that can handle the maximum inflow but at the same time have its best efficiency  point at lower speed. Pumps in sewage pump stations are often over dimensioned with regards to the most common inflow, lowering the speed will in this case result in lower efficiency and more losses. At one point the pump will not be able to overcome the static pressure in the system and will fail to produce any flow. Due to these reasons on/off control will be recommended which also is the most common method of today.

    Stödjande gemenskap: Utveckling och utvärdering av en intervention för livsstilsförändring bland vuxna med adhd2020Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The entire project revolves around a lifestyle intervention that has been developed, implemented and evaluated. The intervention included adults with ADHD and comorbid mental illness. ADHD (Attention Deficiency Hyperactive Disorder) is a neuropsychiatric diagnosis/disability characterized by attention problems, impulsivity and hyperactivity and can affect education, working life, social relationships and form the basis for impaired lifestyle habits. Previous research shows shortened life expectancy in adults with ADHD, which related to deteriorating lifestyle habits. In the long run, the disability may be the basis for impaired living conditions and lifestyle habits and contribute to the individual's well-being and quality of life. In the field of health sciences, it is important to alleviate suffering, promote health and prevent ill health. Thus, the overall aim of this dissertation is to analyze living conditions among people with ADHD and mental illness, as well as to develop and evaluate a lifestyle intervention for this group.

    The PhD project includes four sub-studies: Study I, a qualitative interview study (n = 20) of adults with ADHD and mental illness, aimed at describing experiences of everyday suffering in this group. The analysis showed experiences of both suffering and well-being in living with ADHD. The focus of the suffering was the experience of loneliness, both regarding relationships in life, relationships in health care, but also to ADHD diagnosis and mental illness. Well-being was experienced when diagnosed with ADHD but also in relation to supportive social relationships. Study II, a quantitative descriptive and comparative study, aimed to gain more knowledge about people withADHD and their health situation. One group of people with ADHD (n = 48)was compared to the normal population without ADHD (n = 42). The results showed poorer health outcomes regarding self-perceived general health and the group with ADHD was less weekly physical active but nevertheless had no decreased aerobic fitness compared to the normal population. Study III, aquantitative descriptive study (n = 25), aimed to examine the degree of acceptance of the intervention and its impact on lifestyle habits, health and well-being, MBI and physical fitness. The tests before and after completing intervention showed small positive effects regarding weekly physical activity, quality of life and general- and mental health. Study IV, a qualitative study(n = 15), with adults with ADHD and comorbid mental illness aimed to investigate the experience of participating in a nurse-led lifestyle intervention. The analysis, based on material from interviews, showed that the participants perceived the intervention as supportive, which is related to the interpersonal relationships that arose in the intervention. Through supportive kindship with the other participants in the intervention, lifestyle habits and health experience were improved.

    The conclusion of the thesis is that the lifestyle intervention, based on interpersonal relationships and supported kindship, can be useful for making lifestyle changes in adults with ADHD and mental illness. Such support is important because adults with ADHD and mental illness experience a lack of and a desire for social support and has an increased risk of deteriorating health and unhealthy lifestyles. However, future adjustments to the content of the intervention must be made to improve the lifestyle intervention towards more sustainable lifestyle changes. Above all, the lifestyle intervention ought to be continuous. It is also of great importance for further research that insider perspective is used, that is, investigate the professionals' experiences regarding the intervention.

    Students’ Conceptions of Assessment: A Case Study on Two Classroom-Based Tests for Student Learning in the IB (International Baccalaureate) Programme in Sweden.2020Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study examines IB (International Baccalaureate) students’ conceptions of assessment and their learning outcomes. Twenty pre-DP (Diploma Programme) students from two different classes from a Swedish school were interviewed for this research. Students were given two different tests – essay and short-answered questions – to observe possible differences in learning outcome based on test design. The findings here show that students have a positive outlook on their graded assessment but generally has negative feeling about time constraints for in-class tests. Three main conceptions on the purpose of assessment were found: assessment makes student accountable; assessment describes and measures student learning progress and historical thinking; and assessment improves the quality of their learning. They believe teachers use the information from assessment to improve their teaching. The results also show that students perceive assessment as important and has a number of different effects on their learning. Students emphasise the significance of detailed feedback for their learning. Despite doing two different tests, the students’ conceptions of their learning outcomes were similar to a great extent. Most agree on their deeper understanding of context and different perspectives on the causes of World War One. Students also concur on the improvement of their knowledge on certain concepts, cause and effect relations, and their analytical skills. The students’ results did not show significant difference between classes in the retainment of information by doing an online quiz three weeks after their test. The only slight difference in their responses is that class 1, who wrote the in-class essay, may have learned a bit more in-depth knowledge about nationalism due to their essay question. This study is one of the first in Sweden to examine students’ conceptions of assessment (SCoA) by applying Brown’s (2017) SCoA Codebook and Peterson and Irving’s (2008) model. The results provide insight to how assessment can help students learn based on the learners’ perspective and should be utilised by Swedish and IB educators. However, there are a number of improvements that can be applied for further and more robust research and results.

    Equal health at work?: Protocol for an observational study of work organisation, workload and musculoskeletal complaints among women and men in grocery retail2020In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 10, no 1, article id e032409Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Women generally report more work-related musculoskeletal complaints than men and have higher rates of sickness absence, even within occupations. One likely reason is that work tasks within the occupation are gendered, that is, women and men have different tasks, even when sharing the same job title. Retail is an appealing sector for studying working conditions and work environment in a gender context. The prevalence of work-related complaints is high, physical loads may differ considerably between tasks and the distribution of tasks is likely gendered. The overall aim of this study in retail is to examine factors at the organisational and individual level that may, in a gender perspective, explain working conditions, work tasks, workloads and musculoskeletal health. METHODS AND ANALYSES: Data will be collected in two grocery stores, each with 50-70 workers, at two occasions interspersed by about 1 year. In each of these four waves, data collection will include a web-based questionnaire to all workers addressing, for example, work tasks, psychosocial factors, fatigue and pain; semistructured interviews with managers and approximately 10 workers addressing, for example, competences and decision levels; and technical measurements of postures, movements and heart rate in about 30 workers. The study is novel in combining an organisational gender perspective addressed through qualitative methods with a quantitative analysis of tasks, workload and health. The design allows an examination of both how genders may differ, and why they may differ, as well as analyses of the extent to which gendered working conditions change over time in the two participating stores. ETHICS AND DISSEMINATION: Approval of the study by the Swedish Ethical Review Authority (reference number 2017/404) has been obtained. This work will be disseminated by publication of peer-reviewed papers in scientific journals, presentations at scientific conferences and in meetings with representatives from Swedish retail, including unions and employers' organisations.
